DETAILED DESCRIPTION OF THE INVENTION

[0040] Before describing the present invention in detail, it is to be understood that the invention is not limited to specific separation devices or types of analytical instrumentation, as such may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

[0041] In addition, as used in this specification and the appended claims, the singular article forms "a," "an," and "the" include both singular and plural referents unless the context clearly dictates otherwise. Thus, for example, reference to "a fan" includes a plurality of fans as well as a single fan, reference to a "solar panel" includes a single solar panel as well as a combination of solar panels, and the like. [0042] Furthermore, terminology indicative or suggestive of a particular spatial relationship between elements of the invention is to be construed in a relative sense rather an absolute sense unless the context of usage clearly dictates to the contrary. For example, the terms "over" and "on" as used to describe the spatial orientation of a first item relative to a second item does not necessarily indicate that the first item is located above the second item. Thus, in a cooler that includes a holder placed on or over a smart device, the holder may be located above, at the same level as, or below the smart device depending on the cooler's orientation. Similarly, an "upper" surface of a smart device may lie above, at the same level as, or below other portions of the device depending on the orientation of the device.

[0043] In this specification and in the claims that follow, reference will be made to a number of terms that shall be defined to have the following meanings, unless the context in which they are employed clearly indicates otherwise:

[0044] The terms "electronic," "electronically," and the like are used in their ordinary sense and relate to structures, e.g., semiconductor microstructures, that provide controlled conduction of electrons, holes and/or other charge carriers.

[0045] "Optional" or "optionally" means that the subsequently described

circumstance may or may not occur, so that the description includes instances where the circumstance occurs and instances where it does not.

[0046] The term "smart device" is used herein in its ordinary sense and refers to an electronic device, generally connected to other devices or networks via different wireless protocols such as Bluetooth, NFC, Wi-Fi, 3G, etc. , that can operate to some extent interactively and autonomously. Exemplary smart devices include

[0047] The term "solar panel" is used herein in its ordinary sense and refers to a panel designed to absorb sunlight and/or other photonic radiation as a source of energy for generating electricity.

[0048] In general, the invention provides an easily carriable or portable cooler that includes a fan powered by with one or more solar panels. The fan directs air toward a holder for a smart device such as a smart phone or a smart tablet, thereby cooling the smart device. The cooler can be used outdoors with no power supply, and overcomes the shortcomings of the prior art. That is, a solar powered smart device fan is provided with a much broader spectrum of both portable and fixed operating applications, whereas prior art is application specific.

[0049] Turning now descriptively to the drawings, in which like reference numbers denote like elements throughout the several views, various embodiments of the invention are depicted. With regard to the reference numerals used, the following numbering is used throughout the various drawing figures for single fan embodiments of the invention.

FIG. 7 illustrates the smart device wherein a single fan solar powered cooler is magnetically connected to smart device holder 78. The air flow within and parallel to smart device such as a smartphone or smart tablet wherein the single fan solar powered cooler is magnetically connected to smart device holder 78 is blown vertically by the fan blade 20 coupled to the fan motor spindle 50 for the front fan motor 60. The smart device such as a smartphone or smart tablet is cooled by the air flow produced by the fan blade 20 coupled to the fan motor spindle 50 for the front fan motor 60.

[0054] The single fan solar powered cooler for a smart device addresses specific portions of the bottom surface of the smart device which are to be cooled. That is, the air blown up by the fan blade 20 coupled to the fan motor spindle 50 for the front fan motor 60, which are axial fans, into the smart device holder 78 is directly discharged horizontally through air flow grooves 95 which are long narrow shapes coupled with the circular air passage opening 94. Accordingly, the entire area of the bottom surface of the smart device such as a smartphone or smart tablet is cooled.

[0055] Referring to FIG. 2, FIG. 3, FIG. 4, FIG. 6, FIG. 7 and FIG. 8, air exiting smart device air flow passage 40 and circular vent holes 42 is moved along the bottom surface of the smart device contained within the smart device holder 78, thereby cooling the bottom surface of the smart device. Heat dissipation is carried out at portions of the bottom surface of the smart device with which the air collides. As a result, desired cooling is achieved.

[0056] That is, as shown in FIG. 2, the smart device may be magnetically connected to smart device holder 78 which incorporates air passage opening 94 corresponding in position and size to the location of the protective grille 18 for fan blade 20 coupled to the fan motor spindle 50 for the front fan motor 60 facilitates the continuous vertical alignment of air passage opening 94 with the corresponding protective grille 18 for fan blade 20 coupled to the fan motor spindle 50 for the front fan motor 60. The air passage opening 94 acts as a conduit for guiding air drawn by the fan blade 20 coupled to the fan motor spindle 50 for the front fan motor. The front fan motor 60 are not limited to their positions and number as long as they can blow air into the air passage opening 94. Additionally, a reduction in the height of the front fan motor 60 and the fan motor spindle 50 can reduce the total height of the single fan solar powered cooler for a smart device.

[0057] The single fan solar powered cooler for a smart device constructed as described above can cool the entire bottom surface area of the smart device such as a smartphone or smart tablet by magnetically connecting to smart device holder 78 to the upper fan casing 58.

FIG. 9 provides a perspective view of certain assembled components of the due fan solar powered cooler for a smart device. FIG. 10 and FIG. 16 are exploded perspective views of a dual fan solar powered cooler for a smart device. The device is magnetically connected to smart device holder 278. The holder 278 incorporates air passage opening 294 corresponding in position and size to the location of the front protective grille 218 for front fan blade 220. The holder 278 incorporates air passage opening 298 corresponding in position and size to the location of and rear protective grille 228 for rear fan blade 214. Blade 220 are coupled to the fan motor spindle 250 for the front fan motor 260. The front protective grille 218 and rear protective grille 228 are attached to the upper fan casing 258 using protective grille insertion pegs 224. Air flow is distributed over the bottom surface of smart device by air flow grooves 295 which are long narrow shapes coupled with the circular air passage opening 294 incorporated in the upper surface of smart device holder 278.

[0061] FIG. 10 and FIG. 16 show a dual fan solar powered cooler which includes an upper fan casing 258 for a pair of motors, i.e., front fan motor 260 and rear fan motor 266. Also shown housed by the casing 258 is a front protective grille 218 for front fan blade 220 and a rear protective grille 228 for rear fan blade 214, respectively. Additionally, provided are magnet holders for upper fan casing 234 and magnets for connecting the smart device holder 236, which are held in place by magnet holder placement pegs 237.

As shown in FIG. 10, the bottom fan casing 274 also incorporates upper snap fastener 286, lower snap fastener insert 288, and bottom fan casing air inlets 290. Circular vent holes 242 are formed in the upper fan casing 258 for front fan motor 260 and rear fan motor 266. Smart device air flow passage 240 and circular vent holes 242 for front fan motor 260 and rear fan motor 266 correspond in position and size to the location of the front protective grille 218 for front fan blade 220 and rear protective grille 228 for rear fan blade 214, which are coupled to the fan motor spindle 250 for front fan motor 260 and rear fan motor 266, respectively.

[0063] FIG. 15 is a side sectional view along cut line XIII-XIII of FIG. 11 illustrates the smart device wherein the dual fan solar powered cooler is magnetically connected to smart device holder 278. Air flow within and parallel to smart device wherein the dual fan solar powered cooler is magnetically connected to smart device holder 278 is forced perpendicular to the front fan blade 220 and rear fan blade 214 coupled to their fan motor spindle 250 for front fan motor 260 and rear fan motor 266, respectively. The smart device is thereby cooled by the air flow produced by the front fan blade 220 and rear fan blade 214 coupled to their fan motor spindle 250 for front fan motor 260 and rear fan motor 266, respectively.

[0064] As shown FIG. 10 and FIG. 16, the dual fan solar powered cooler for a smart device addresses specific portions of the bottom surface of the smart device which are to be cooled. That is, the air is blown upward by the front fan blade 220 and rear fan blade 214, which are coupled to their fan motor spindle 250 for the front fan motor 260 and rear fan motor 266, respectively. Air from these axial fans is introduced into the smart device holder 278 and directly discharged upward flowing air through air flow grooves 295 which are long narrow shapes coupled with the circular air passage opening 294. Accordingly, the entire area of the bottom surface of the smart device such as a smartphone or smart tablet is cooled.

[0065] Referring to FIG. 11, FIG. 12, FIG. 14, and FIG. 15, the air exiting smart device air flow passage 240 and circular vent holes 242 is moved along the bottom surface of the smart device such as a smartphone or smart tablet contained within the smart device holder 278, thereby cooling the bottom surface of the smart device such as a smartphone or smart tablet. Portions of the bottom surface of the smart device with which the air collides are cooled via heat dissipation. That is, magnetically connected to smart device holder 278 which incorporates air passage opening 294 corresponding in position and size to the location of the front protective grille 218 for front fan blade 220 and rear protective grille 228 for rear fan blade 214. Fan motor spindle 250 for the front fan motor 260 facilitates the continuous vertical alignment of air passage opening 294 with the corresponding front protective grille 218 and rear protective grille 228 coupled to their fan motor spindle 250, respectively. The air passage opening 294 acts as a conduit for guiding air drawn by the front fan blade 220 and rear fan blade 214 coupled to their fan motor spindle 250 for the front fan motor, respectively. The front fan motor 260 and rear fan motor 266, are not limited to their positions and number as long as they can blow air into the air passage opening 294.

Additionally, a reduction in the height of the front fan motor 260 and rear fan motor 266, and their respective fan motor spindle 250 can reduce the total height of the dual fan solar powered cooler for a smart device.

[0066] The dual fan solar powered cooler for a smart device constructed as described above can cool the entire bottom surface area of the smart device such as a smartphone or smart tablet by magnetically connected to smart device holder 278 to the upper fan casing 258. All of the individual components are glued to their corresponding connecting parts to remain in place, respectively.

[0067] In sum, air suction openings for dual fan solar powered cooler for smart device are shown as smart device air flow passage 240. Circular vent holes 242 are formed on top surface of a housing upper fan casing 258 for front fan motor 260 and rear fan motor 266. Bottom fan casing air inlet 290 is located in bottom fan casing 274. An exhaust opening is formed on the top surface of a housing upper fan casing 258 through front protective grille 218 for front fan blade 220 and through rear protective grille 228 for rear fan blade 214, each circulating air flow through a smart device holder 278 with dual air passage openings 294 and 298 with air flow grooves 295 in smart device holder 278 for cooling the bottom surface of the smart device. The solar panel 270 for front fan motor 260 and rear fan motor 266 is connected to positive terminal point 271 and negative terminal point 272 using electric connector wiring 268 so that the fan motors may be driven by means of its power generation output. Thus, this portable type solar powered fan can be used simply without any place restrictions.

[0068] As described above, the invention allows air to uniformly collide with a bottom surface of a smart device such as a smartphone or smart tablet. As a result, the invention provides more effectively cooling of the smart device when compared conventional implementations of fans in combination with smart devices.

[0069] The invention may exhibit a number of other advantages as well. For example, wind produced by the fan is typically effective to cool excessive temperatures, and may be directly and personally used by individual away from their usual premises and without any power mains supply available (for example train compartment etc.). That is, individuals may wish to protect themselves from or to alleviate excessive temperatures or their unpleasant attendant manifestations (including perspiration) through the use of the invention. Prior art fans are fundamentally unsuitable for this because they are generally too large and bulky and/or because they do not have an independent power supply. That is, they are tied to buildings.

[0070] In contrast, the invention provides a light, handy design and is equipped with built-in and independent power supply facilities. These independent electrical energy sources in particular may comprise an accumulator, with a charging device and a mains connection, a storage battery, also with a charging device and a mains connection, a dry battery and last but not least solar power on the basis of the photo-voltaic effect.

[0071] The invention may also help prevent smart devices from overheating, or catching on fire. Some prior art devices are fundamentally unsuitable for extemal use outside of a motor vehicles air conditioning vent.

[0072] Variations of the invention are possible. For example, multiple solar panels can be used for two or more fan motors, in series, parallel or in the combination of these. Such panels may be formed from a plurality of photovoltaic cells immobilized relative to the smart device. The cells form a solar panel that converts sunlight and other photonic radiant energy electric power. Similarly, in some embodiments, at least one blowing fan and at least one exhaust fan and electrically connected to the output terminals of the electric connector.

[0073] It is to be understood that, while the invention has been described in conjunction with the preferred specific embodiments thereof, the foregoing description merely illustrates and does not limit the scope of the invention. Numerous alternatives and equivalents exist which do not depart from the invention set forth above. For example, any particular embodiment of the invention, e.g., those depicted in any drawing herein, may be modified to include or exclude features of other embodiments. Other aspects, advantages, and modifications within the scope of the invention will be apparent to those skilled in the art to which the invention pertains.
