Description:
Cigarette Lighter with a New Fuel Release System

Yuzo Ochiai

Attorney Docket No. 19-07-8469

BACKGROUND

[0001] 1. Field

[0002] This specification relates to a cigarette lighter. More specifically, this specification relates to a cigarette lighter with a new fuel release system.

G0003] 2. Description of the Related Art

[0004] Cigarette lighters that are equipped with a pre-mixing burner flame generating unit, such as jet flame or turbo flame lighters, offer numerous advantages over other forms of lighters. The biggest advantages include a more windproof flame as well as a more complete combustion of the combustible fuel. However, most cigarette lighters that are equipped with a pre -mixing burner flame generating unit use a piezoelectric ignition to ignite the combustible fuel (i.e. butane). While piezoelectric ignitions are generally reliable they do not offer the simplicity of manufacturing and increased reliability that traditional flint ignitions are able to inherently offer. [0005] What is needed is a cigarette lighter that combines the enhanced burning characteristics of the pre-mixing burner flame generating unit with the simplicity and reliability of traditional flint ignitions. However, traditional flint ignitions are not used with pre-mixing burner flame generating units because of inherent functional reliability issues. The main culprit behind these functional reliability issues lie in the improper timing between the release of the combustible fuel and the sparks emitted by traditional flint ignitions. More specifically, the sparks emitted by traditional flint ignitions are generated too early to reliably ignite the gas. For example, when a user actuates the friction wheel assembly with their thumb, sparks are generated before their thumb has a chance to actuate the gas lever. This results in unreliable combustion of the combustible fuel and frustration for the user.

[0006] Previous cigarette lighters that attempted to address the above issues, for example the Wind Master and Wind Master 2 cigarette lighters by Windmill, resulted in increased complexity of both the design and function of the cigarette lighter as well as the associated manufacturing. Additional cigarette lighters, for example the AM7101 and AM369 by Wenzhou Zhibo Light Industrial Products Co., LTD, resulted in cigarette lighters that pose increased safety risks to the user to the user.

[0007] Therefore, there exists a need for a cigarette lighter that combines a pre -mixing burner flame generating unit with a traditional flint ignition without the above-mentioned drawbacks.

DETAILED DESCRIPTION

[00027] In the following detailed description, numerous specific details are set forth to provide an understanding of the present disclosure. It will be apparent however, to one of ordinary skill in the art that elements of the present disclosure may be practiced without some of these specific details. In other instances, well-known structures and techniques have not been shown in detail to avoid unnecessarily obscuring the present disclosure. [00028] FIG. 1 illustrates a cross sectional view of a cigarette lighter 100 according to an embodiment of the invention. The cigarette lighter 100 includes a body extending along an axis and having a first end 102 and a second end 104 opposite the first end 102. The cigarette lighter 100 is depicted as rectangular in shape. However, other shapes may be used interchangeably according to various embodiments. For example, the cigarette lighter 100 may be square, cylindrical, hexagonal, or spherical in shape. The body of the cigarette lighter 100 may be formed from plastic, metal, or a combination of plastic and metal.

[00029] The cigarette lighter 100 includes a fuel reservoir 101 located within the body. In other embodiments, the fuel reservoir 101 may form part of the body of the cigarette lighter 100. For example, the fuel reservoir 101 may be in the form of a casing that allows a user to grip the surface. In some embodiments, the fuel reservoir 101 may be detachable from the other components of the cigarette lighter 100. The fuel reservoir 101 may be configured to contain a combustible fuel. For example, the fuel reservoir 101 may be configured to contain butane. [00030] The cigarette lighter 100 includes a pre-mixing burner flame generating unit 103. The pre-mixing burner flame generating unit 103 may be located adjacent to the first end 102 of the body. In other embodiments, the pre-mixing burner flame generating unit 103 may be located elsewhere on the body of the cigarette lighter 100. For example, the pre-mixing burner flame generating unit 103 may be located between the first end 102 and the second end 104 of the body. The pre-mixing burner flame generating unit 103 may be configured to mix the combustible fuel with air and at least partially contain a flame.

[00031] The cigarette lighter 100 includes a valve 105 in fluidic communication with the fuel reservoir 101 and the pre-mixing burner flame generating unit 103. The valve 105 may be configured to facilitate the combustible fuel to enter the pre-mixing burner flame generating unit 103 when the valve 105 is actuated. The valve 105 may be in mechanical communication with an adjustor 121. The adjustor 121 may allow a user to adjust the amount of combustible fuel released into the pre-mixing burner flame generating unit 103 when the valve 105 is actuated. The adjustor 121 may be configured to allow continuous adjustment through a range of settings similar to the function of a volume knob on a stereo. In other embodiments, the adjustor 121 may be configured to allow only incremental adjustments. For example, the adjustor 121 may be configured to allow a user to select a low, medium, and high setting. However, other forms of adjusting may be used interchangeably according to various embodiments.

[00032] The cigarette lighter 100 may include a bracket 107. The bracket 107 may be in mechanical communication with the valve 105 and configured to actuate the valve 105 when a force is applied to the bracket 107 by a user. The cigarette lighter 100 may further include a gas lever 113 in mechanical communication with the valve 105 and the bracket 107. The gas lever 113 may be configured to facilitate actuation of the valve 105 when a force is applied to the bracket 107 by a user. In some embodiments, the gas lever 113 may rotate about a gas lever fulcrum 115. For example, when the bracket 107 is pushed down along the A” axis, the portion of the gas lever 113 immediately adjacent to the bracket 107 is also pushed down. The gas lever 113 rotates about the gas lever fulcrum 115 such that the portion of the gas lever 113 immediately adjacent to the valve 105 pushes up on the valve 105. When the valve 105 is pushed up, the valve 105 is actuated which releases the combustible fuel into the pre-mixing burner flame generating unit 103.

[00033] In some embodiments, the bracket 107 and the gas lever 113 may be mechanically coupled together. For example, the bracket 107 and the gas lever 113 may be pinned, screwed, or glued together. In other embodiments, the bracket 107 and the gas lever 113 may be a single integrated component. Still in other embodiments, the bracket 107 and the gas lever 113 may be separate components in mechanical communication with each other.

[00034] The cigarette lighter 100 may include a thumb ledge 119 mechanically coupled to the bracket 107. For example, the bracket 107 and the thumb ledge 119 may be pinned, screwed, or glued together. Tn other embodiments, the bracket 107 and the thumb ledge 119 may be a single integrated component. The thumb ledge 119 may be configured to allow a user to exert a force on the bracket 107.

[00035] The cigarette lighter 100 may include a friction wheel assembly 109. The friction wheel assembly 109 may be in mechanical communication with the bracket 107 and may be configured to rotate about an axis. For example, the friction wheel assembly 109 may rotate about an axis A’.

[00036] The cigarette lighter 100 may include a flint 111. The flint 111 may be in mechanical communication with the friction wheel assembly 109 and may be configured to emit sparks when the friction wheel assembly 109 is rotated about the axis by a user. For example, the flint 111 may emit sparks when the friction wheel assembly 109 is rotated about the axis A’ by a user.

[00037] The cigarette lighter 100 may include a spring 117. The spring 117 may be placed adjacent to the flint 111 such that the flint 111 is located between the friction wheel assembly 109 and the spring 117. The spring 117 may be configured to apply a spring force on the flint 111 to force the flint 111 against the friction wheel assembly 109. This may allow for a more reliable generation of sparks due to the flint 111 being forced against the friction wheel assembly 109. In some embodiments, the spring force may lie along an axis that is perpendicular to the axis of rotation of the friction wheel assembly 109. For example, the spring force may lie along an axis that is perpendicular to axis A’. In some embodiments, the bracket 107 may be configured to actuate along an axis parallel to the axis of the spring force. For example, the bracket 107 may be configured to actuate along axis A”.

[00038] In some embodiments, the spring 117 and the flint 111 may be located within the bracket 107. For example, the bracket 107 may have a cavity where the flint 111 and the spring 117 are located. In some embodiments, the friction wheel assembly 109 may be coupled to the bracket 107. In other embodiments, the friction wheel assembly 109 may be coupled to the body of the cigarette lighter 100 via a flexible coupler. For example, the friction wheel assembly 109 may be coupled to the first end 102 of the body and positioned such that the flint 111 and the spring 117 are prevented from leaving the cavity of the bracket 107.

[00039] FIG. 2 illustrates a cross sectional view of the cigarette lighter 100 from FIG. 1 according to an embodiment of the invention. More specifically, FIG. 2 illustrates the actuation of the cigarette lighter 100 by a user.

[00040] To actuate the cigarette lighter 100, a user may first initiate a gas discharge operation. According to various embodiments, the gas discharge operation is as follows. A user may first apply a downward force on the friction wheel assembly 109. The downward force causes the friction wheel assembly 109 and the bracket 107 to move down under the downward force from the user. As the bracket 107 moves down it causes the gas lever 113 to rotate about the gas lever fulcrum 115. As the gas lever 113 rotates a portion of the gas lever 113 actuates the valve 105. When the valve 105 is actuated, the combustible fuel is released from the fuel reservoir 101 and enters the pre-mixing burner flame generating unit 103.

[00041] Next a user may then initiate an ignition operation. According to various embodiments, the ignition operation is as follows. While the user is applying a downward force on the friction wheel assembly 109, the user may apply a rotational force to the friction wheel assembly 109. When the friction wheel assembly 109 receives the rotational force by the user, the friction wheel assembly 109 rotates against a surface of the flint 111 to cause the flint 111 to emit sparks 123. When the sparks 123 contact the combustible fuel in the pre -mixing burner flame generating unit 103 a flame 125 is produced. The pre -mixing burner flame generating unit 103 will continue to hold the flame 125 for as long as the combustible fuel is being supplied to it. For example, the pre-mixing burner flame generating unit 103 will continue to hold the flame 125 as long as the user keeps applying a downward force to the friction wheel assembly 109 or the bracket 107.

[00042] In some embodiments, the gas discharge operation and the friction operation may be performed simultaneously by a user. For example, a user may simultaneously apply a downward force on the friction wheel assembly 109 while also applying a rotational force to the friction wheel assembly 109. Under this scenario, the user causes sparks 123 to be generated at the same time the combustible fuel is being supplied to the pre-mixing burner flame generating unit 103 which produces the flame 125.

[00043] In other embodiments, a user may simultaneously apply a downward force on the friction wheel assembly 109 while also applying a rotational force to the friction wheel assembly 109 before the user shifts to a downward force to the bracket 107. Under this scenario, the user causes sparks 123 to be generated at the same time the combustible fuel is being supplied to the pre-mixing burner flame generating unit 103. After the flame 125 is generated the user shifts the downward force to bracket 107 to continue supplying the combustible fuel to the pre-mixing burner flame generating unit 103 which ensures an uninterrupted flame 125.

[00044] FIG. 3 illustrates a cross sectional view of a cigarette lighter 300 according to an embodiment of the invention. The cigarette lighter 300 includes a body extending along an axis and having a first end 302 and a second end 304 opposite the first end 302.

For example, the cigarette lighter 300 may be square, cylindrical, hexagonal, or spherical in shape. The body of the cigarette lighter 300 may be formed from plastic, metal, or a combination of plastic and metal.

[00045] The cigarette lighter 300 includes a fuel reservoir 301 located within the body. In other embodiments, the fuel reservoir 301 may form part of the body of the cigarette lighter 300. For example, the fuel reservoir 301 may be in the form of a casing that allows a user to grip the surface. In some embodiments, the fuel reservoir 301 may be detachable from the other components of the cigarette lighter 300. The fuel reservoir 301 may be configured to contain a combustible fuel.

[00047] The cigarette lighter 300 includes a valve 305 in fluidic communication with the fuel reservoir 301 and the pre-mixing burner flame generating unit 303. The valve 305 may be configured to facilitate the combustible fuel to enter the pre-mixing burner flame generating unit 303 when the valve 305 is actuated. The valve 305 may be in mechanical communication with an adjustor 321.

The adjustor 321 may be configured to allow continuous adjustment through a range of settings similar to the function of a volume knob on a stereo. In other embodiments, the adjustor 321 may be configured to allow only incremental adjustments. For example, the adjustor 321 may be configured to allow a user to select a low, medium, and high setting.

[00049] In some embodiments, the gas discharge and ignition operating unit 327 may include a gas lever 313, a bracket 307, a friction wheel assembly 309, and a flint 302. The gas lever 313 may be in mechanical communication with the valve 305 and configured to rotate about a gas lever fulcrum 315. The gas lever 313 may be configured to facilitate actuation of the valve 305 when the gas lever 313 is actuated. The bracket 307 may be in mechanical communication with the gas lever 313. The bracket 307 may be configured to actuate the gas lever 313 when a force parallel to the axis of the body is applied to the bracket 307 by a user.

[00052] The cigarette lighter 300 may include a spring 317. The spring 317 may be placed adjacent to the flint 311 such that the flint 311 is located between the friction wheel assembly 309 and the spring 317. The spring 317 may be configured to apply a spring force on the flint 311 to force the flint 311 against the friction wheel assembly 309. This may allow for a more reliable generation of sparks due to the flint 311 being forced against the friction wheel assembly 309. In some embodiments, the spring force may lie along an axis that is perpendicular to the axis of rotation of the friction wheel assembly 309. For example, the spring force may lie along an axis that is perpendicular to axis A’. In some embodiments, the bracket 307 may be configured to actuate along an axis parallel to the axis of the spring force. For example, the bracket 307 may be configured to actuate along axis A”.

[00053] In some embodiments, the spring 317 and the flint 311 may be located within the bracket 307. For example, the bracket 307 may have a cavity where the flint 311 and the spring 317 are located. In some embodiments, the friction wheel assembly 309 may be coupled to the bracket 307. In other embodiments, the friction wheel assembly 309 may be coupled to the body of the cigarette lighter 300 via a flexible coupler. For example, the friction wheel assembly 309 may be coupled to the first end 302 of the body and positioned such that the flint 311 and the spring 317 are prevented from leaving the cavity of the bracket 307.

[00054] FIG. 4A illustrates a cross sectional view of a cigarette lighter 400 according to an embodiment of the invention. The cigarette lighter 400 includes a body extending along an axis and having a first end 402 and a second end 404 opposite the first end 402. The cigarette lighter 400 is depicted as rectangular in shape. However, other shapes may be used interchangeably according to various embodiments. For example, the cigarette lighter 400 may be square, cylindrical, hexagonal, or spherical in shape. The body of the cigarette lighter 400 may be formed from plastic, metal, or a combination of plastic and metal.

[00055] The cigarette lighter 400 includes a separate fuel reservoir 401 that forms at least part of the body. The fuel reservoir 401 may be configured to contain a combustible fuel. For example, the fuel reservoir 401 may be configured to contain butane.

[00056] The cigarette lighter 400 includes a pre-mixing burner flame generating unit 403. The pre-mixing burner flame generating unit 403 may be located adjacent to the first end 402 of the body. In other embodiments, the pre-mixing burner flame generating unit 403 may be located elsewhere on the body of the cigarette lighter 400. For example, the pre-mixing burner flame generating unit 403 may be located between the first end 402 and the second end 404 of the body. The pre-mixing burner flame generating unit 403 may be configured to mix the combustible fuel with air and at least partially contain a flame.

[00057] The cigarette lighter 400 includes a valve 405 in fluidic communication with the fuel reservoir 401 and the pre-mixing burner flame generating unit 403. The valve 405 may be configured to facilitate the combustible fuel to enter the pre-mixing burner flame generating unit 403 when the valve 405 is actuated. The valve 405 may be in mechanical communication with an adjustor 421. The adjustor 421 may allow a user to adjust the amount of combustible fuel released into the pre-mixing burner flame generating unit 403 when the valve 405 is actuated. The adjustor 421 may be configured to allow continuous adjustment through a range of settings similar to the function of a volume knob on a stereo. In other embodiments, the adjustor 421 may be configured to allow only incremental adjustments. For example, the adjustor 421 may be configured to allow a user to select a low, medium, and high setting. However, other forms of adjusting may be used interchangeably according to various embodiments.

[00058] The cigarette lighter 400 may include a bracket 407. The bracket 407 may be in mechanical communication with the valve 405 and configured to actuate the valve 405 when a force is applied to the bracket 407 by a user. The cigarette lighter 400 may further include a gas lever 413 in mechanical communication with the valve 405 and the bracket 407. The gas lever 413 may be configured to facilitate actuation of the valve 405 when a force is applied to the bracket 407 by a user. In some embodiments, the gas lever 413 may rotate about a gas lever fulcrum 415. For example, when the bracket 407 is pushed down, the portion of the gas lever 413 immediately adjacent to the bracket 407 is also pushed down. The gas lever 413 rotates about the gas lever fulcrum 415 such that the portion of the gas lever 413 immediately adjacent to the valve 405 pushes up on the valve 405. When the valve 405 is pushed up, the valve 405 is actuated which releases the combustible fuel into the pre-mixing burner flame generating unit 403.

[00059] In some embodiments, the bracket 407 and the gas lever 413 may be mechanically coupled together. For example, the bracket 407 and the gas lever 413 may be pinned, screwed, or glued together. Tn other embodiments, the bracket 407 and the gas lever 413 may he a single integrated component. Still in other embodiments, the bracket 407 and the gas lever 413 may be separate components in mechanical communication with each other.

[00060] The cigarette lighter 400 may include a thumb ledge 419 mechanically coupled to the bracket 407. For example, the bracket 407 and the thumb ledge 419 may be pinned, screwed, or glued together. In other embodiments, the bracket 407 and the thumb ledge 419 may be a single integrated component. The thumb ledge 419 may be configured to allow a user to exert a force on the bracket 407.

[00061] The cigarette lighter 400 may include a friction wheel assembly 409. The friction wheel assembly 409 may be in mechanical communication with the bracket 407 and may be configured to rotate about an axis . The cigarette lighter 400 may include a flint 411. The flint 411 may be in mechanical communication with the friction wheel assembly 409 and may be configured to emit sparks when the friction wheel assembly 409 is rotated about the axis by a user.

[00062] The cigarette lighter 400 may include a spring 417. The spring 417 may be placed adjacent to the flint 411 such that the flint 411 is located between the friction wheel assembly 409 and the spring 417. The spring 417 may be configured to apply a spring force on the flint 411 to force the flint 411 against the friction wheel assembly 409. This may allow for a more reliable generation of sparks due to the flint 411 being forced against the friction wheel assembly 409. In some embodiments, the spring force may lie along an axis that is perpendicular to the axis of rotation of the friction wheel assembly 409. In some embodiments, the bracket 407 may be configured to actuate along an axis parallel to the axis of the spring force.

[00063] In some embodiments, the spring 417 and the flint 411 may be located within the bracket 407. For example, the bracket 407 may have a cavity where the flint 411 and the spring 417 are located. In some embodiments, the friction wheel assembly 409 may be coupled to the bracket 407. In other embodiments, the friction wheel assembly 409 may be coupled to the body of the cigarette lighter 400 via a flexible coupler. For example, the friction wheel assembly 409 may be coupled to the first end 402 of the body and positioned such that the flint 411 and the spring 417 are prevented from leaving the cavity of the bracket 407.

[00064] FIG. 4B illustrates a cross sectional view of the cigarette lighter 400 from FIG. 4A according to an embodiment of the invention. More specifically, FIG. 4B illustrates the actuation of the cigarette lighter 400 by a user.

[00065] To actuate the cigarette lighter 400, a user may first initiate a gas discharge operation. According to various embodiments, the gas discharge operation is as follows. A user may first apply a downward force on the friction wheel assembly 409. The downward force causes the friction wheel assembly 409 and the bracket 407 to move down under the downward force from the user. As the bracket 407 moves down it causes the gas lever 413 to rotate about the gas lever fulcrum 415. As the gas lever 413 rotates a portion of the gas lever 413 actuates the valve 405. When the valve 405 is actuated, the combustible fuel is released from the fuel reservoir 401 and enters the pre-mixing burner flame generating unit 403.

[00066] Next a user may then initiate an ignition operation. According to various embodiments, the ignition operation is as follows. While the user is applying a downward force on the friction wheel assembly 409, the user may apply a rotational force to the friction wheel assembly 409. When the friction wheel assembly 409 receives the rotational force by the user, the friction wheel assembly 409 rotates against a surface of the flint 411 to cause the flint 411 to emit sparks. When the sparks contact the combustible fuel in the pre-mixing burner flame generating unit 403 a flame is produced. The pre-mixing burner flame generating unit 403 will continue to hold the flame for as long as the combustible fuel is being supplied to it. For example, the pre mixing burner flame generating unit 403 will continue to hold the flame as long as the user keeps applying a downward force to the friction wheel assembly 409 or the bracket 407.

[00067] In some embodiments, the gas discharge operation and the friction operation may be performed simultaneously by a user. For example, a user may simultaneously apply a downward force on the friction wheel assembly 409 while also applying a rotational force to the friction wheel assembly 409. Under this scenario, the user causes sparks to be generated at the same time the combustible fuel is being supplied to the pre-mixing burner flame generating unit 403 which produces the flame.

[00068] In other embodiments, a user may simultaneously apply a downward force on the friction wheel assembly 409 while also applying a rotational force to the friction wheel assembly 409 before the user shifts to a downward force to the bracket 407. Under this scenario, the user causes sparks to be generated at the same time the combustible fuel is being supplied to the pre mixing burner flame generating unit 403. After the flame is generated the user shifts the downward force to bracket 407 to continue supplying the combustible fuel to the pre -mixing burner flame generating unit 403 which ensures an uninterrupted flame.

[00069] FIG. 5A illustrates a cross sectional view of a cigarette lighter 500 according to an embodiment of the invention. The cigarette lighter 500 includes a body extending along an axis and having a first end 502 and a second end 504 opposite the first end 502. The cigarette lighter 500 is depicted as rectangular in shape. However, other shapes may be used interchangeably according to various embodiments. For example, the cigarette lighter 500 may be square, cylindrical, hexagonal, or spherical in shape. The body of the cigarette lighter 500 may be formed from plastic, metal, or a combination of plastic and metal.

[00070] The cigarette lighter 500 includes an integral fuel reservoir 501 within the body. The fuel reservoir 501 may be configured to contain a combustible fuel. For example, the fuel reservoir 501 may be configured to contain butane.

[00071] The cigarette lighter 500 includes a pre-mixing burner flame generating unit 503. The pre-mixing burner flame generating unit 503 may be located adjacent to the first end 502 of the body. In other embodiments, the pre-mixing burner flame generating unit 503 may be located elsewhere on the body of the cigarette lighter 500. For example, the pre-mixing burner flame generating unit 503 may be located between the first end 502 and the second end 504 of the body. The pre-mixing burner flame generating unit 503 may be configured to mix the combustible fuel with air and at least partially contain a flame.

[00072] The cigarette lighter 500 includes a valve 505 in fluidic communication with the fuel reservoir 501 and the pre-mixing burner flame generating unit 503. The valve 505 may be configured to facilitate the combustible fuel to enter the pre-mixing burner flame generating unit 503 when the valve 505 is actuated.

[00073] The cigarette lighter 500 may include a bracket 507. The bracket 507 may be in mechanical communication with the valve 505 and configured to actuate the valve 505 when a force is applied to the bracket 507 by a user. The cigarette lighter 500 may further include a gas lever 513 in mechanical communication with the valve 505 and the bracket 507. The gas lever 513 may be configured to facilitate actuation of the valve 505 when a force is applied to the bracket 507 by a user. In some embodiments, the gas lever 513 may rotate about a gas lever fulcrum. For example, when the bracket 507 is pushed down, the portion of the gas lever 513 immediately adjacent to the bracket 507 is also pushed down. The gas lever 513 rotates about the gas lever fulcrum such that the portion of the gas lever 513 immediately adjacent to the valve 505 pushes up on the valve 505. When the valve 505 is pushed up, the valve 505 is actuated which releases the combustible fuel into the pre-mixing burner flame generating unit 503.

[00074] In some embodiments, the bracket 507 and the gas lever 513 may be mechanically coupled together. For example, the bracket 507 and the gas lever 513 may be pinned, screwed, or glued together. In other embodiments, the bracket 507 and the gas lever 513 may be a single integrated component. Still in other embodiments, the bracket 507 and the gas lever 513 may be separate components in mechanical communication with each other.

[00075] The cigarette lighter 500 may include a thumb ledge 519 mechanically coupled to the bracket 507. For example, the bracket 507 and the thumb ledge 519 may be pinned, screwed, or glued together. In other embodiments, the bracket 507 and the thumb ledge 519 may be a single integrated component. The thumb ledge 519 may be configured to allow a user to exert a force on the bracket 507.

[00076] The cigarette lighter 500 may include a friction wheel assembly 509. The friction wheel assembly 509 may be in mechanical communication with the bracket 507 and may be configured to rotate about an axis. The cigarette lighter 500 may include a flint 511. The flint 511 may be in mechanical communication with the friction wheel assembly 509 and may be configured to emit sparks when the friction wheel assembly 509 is rotated about the axis by a user.

[00077] The cigarette lighter 500 may include a spring 517. The spring 517 may be placed adjacent to the flint 511 such that the flint 511 is located between the friction wheel assembly 509 and the spring 517. The spring 517 may be configured to apply a spring force on the flint 511 to force the flint 511 against the friction wheel assembly 509. This may allow for a more reliable generation of sparks due to the flint 511 being forced against the friction wheel assembly 509. In some embodiments, the spring force may lie along an axis that is perpendicular to the axis of rotation of the friction wheel assembly 509. Tn some embodiments, the bracket 507 may be configured to actuate along an axis parallel to the axis of the spring force.

[00078] In some embodiments, the spring 517 and the flint 511 may be located within the bracket 507. For example, the bracket 507 may have a cavity where the flint 511 and the spring 517 are located. In some embodiments, the friction wheel assembly 509 may be coupled to the bracket 507. In other embodiments, the friction wheel assembly 509 may be coupled to the body of the cigarette lighter 500 via a flexible coupler. For example, the friction wheel assembly 509 may be coupled to the first end 502 of the body and positioned such that the flint 511 and the spring 517 are prevented from leaving the cavity of the bracket 507.

[00079] FIG. 5B illustrates a cross sectional view of the cigarette lighter 500 from FIG. 5A according to an embodiment of the invention. More specifically, FIG. 5B illustrates the actuation of the cigarette lighter 500 by a user.

[00080] To actuate the cigarette lighter 500, a user may first initiate a gas discharge operation. According to various embodiments, the gas discharge operation is as follows. A user may first apply a downward force on the friction wheel assembly 509. The downward force causes the friction wheel assembly 509 and the bracket 507 to move down under the downward force from the user. As the bracket 507 moves down it causes the gas lever 513 to rotate about the gas lever fulcrum. As the gas lever 513 rotates a portion of the gas lever 513 actuates the valve 505. When the valve 505 is actuated, the combustible fuel is released from the fuel reservoir 501 and enters the pre-mixing burner flame generating unit 503. [00081] Next a user may then initiate an ignition operation. According to various embodiments, the ignition operation is as follows. While the user is applying a downward force on the friction wheel assembly 509, the user may apply a rotational force to the friction wheel assembly 509. When the friction wheel assembly 509 receives the rotational force by the user, the friction wheel assembly 509 rotates against a surface of the flint 511 to cause the flint 511 to emit sparks. When the sparks contact the combustible fuel in the pre-mixing burner flame generating unit 503 a flame is produced. The pre-mixing burner flame generating unit 503 will continue to hold the flame for as long as the combustible fuel is being supplied to it. For example, the pre- mixing burner flame generating unit 503 will continue to hold the flame as long as the user keeps applying a downward force to the friction wheel assembly 509 or the bracket 507.

[00082] In some embodiments, the gas discharge operation and the friction operation may be performed simultaneously by a user. For example, a user may simultaneously apply a downward force on the friction wheel assembly 509 while also applying a rotational force to the friction wheel assembly 509. Under this scenario, the user causes sparks to be generated at the same time the combustible fuel is being supplied to the pre-mixing burner flame generating unit 503 which produces the flame.

[00083] In other embodiments, a user may simultaneously apply a downward force on the friction wheel assembly 509 while also applying a rotational force to the friction wheel assembly 509 before the user shifts to a downward force to the bracket 507. Under this scenario, the user causes sparks to be generated at the same time the combustible fuel is being supplied to the pre- mixing burner flame generating unit 503. After the flame is generated the user shifts the downward force to bracket 507 to continue supplying the combustible fuel to the pre -mixing burner flame generating unit 503 which ensures an uninterrupted flame. [00084] FIG. 6A illustrates a cross sectional view of a cigarette lighter 600 according to an embodiment of the invention. The cigarette lighter 600 includes many of the same features as cigarette lighters 100, 200, 300, 400, and 500, and have been similarly numbered accordingly. [00085] Cigarette lighter 600 includes a slide lock 627 that may be actuated by a user to prevent accidental discharge of the combustible fuel. As depicted in FIG. 6A, the slide lock 627 is in the actuated “locked” position. In some embodiments, the slide lock 627 may prevent the gas lever 613 from being unintentionally actuated. In other embodiments, the slide lock 627 may prevent the thumb ledge 619 from being depressed.

[00086] FIG. 6B illustrates a cross sectional view of the cigarette lighter 600 from FIG. 6A according to an embodiment of the invention. As depicted in FIG. 6B, the slide lock 627 is in the “unlocked” position which allows a user to operate the cigarette lighter 600.

The cigarette lighter 700 includes many of the same features as cigarette lighters 100, 200, 300, 400, and 500, and have been similarly numbered accordingly. [00088] Cigarette lighter 700 includes a resistance spring 729 to help prevent accidental discharge of the combustible fuel. The resistance spring 729 provides a resisting force against the actuation of the cigarette lighter 700 that a user must overcome in order to operate the cigarette lighter 700.

[00089] FIGS. 8A-8C illustrate a cross sectional view of a cigarette lighter 800 according to an embodiment of the invention. The cigarette lighter 800 includes many of the same features as cigarette lighters 100, 200, 300, 400, and 500, and have been similarly numbered accordingly. [00090] As depicted in FIGS . 8A-8C, the gas discharge assembly which includes the bracket

807, the gas lever 813, and the thumb ledge 819 are separate from the ignition assembly which includes the friction wheel 809, the flint 811, and the spring 817. For example, a user may be able to actuate the gas discharge assembly and the ignition assembly independently of the other. [00091] FIG. 8A illustrates the resting “initial” state of the cigarette lighter 800. FIG. 8B illustrates the ignition operation (e.g. actuation of the gas discharge assembly and the ignition assembly by a user). FIG. 8C illustrates the continuous state where a flame has been generated and the user is continuously actuating the gas discharge assembly for a continuous flame.
