Background Art In general, a bidet is a machine that is fixed to one side of a toilet bowl, and injects washing water under high pressure to the genitals or the posterior parts of a human body in order to bathe or massage the parts according to a user's operation.

The machine has an advantage of leaving the user with a feeling of freshness and cleanness by getting rid of foreign matter or pollution after stool, and has a high

remedial effect of reducing the frequency of many ailments common to the perianal area. Thus, it is gradually popularized.

The bidet, however, has a drawback in that it can be used only in places where it is installed. Therefore, if a person goes out or takes a trip and eases himself at a toilet where a bidet is not installed, he should wipes the parts with a toilet paper. The acting fails to leave the user with a feeling of freshness and cleanness and makes him unpleasant. Disadvantageously, there are cases where waste matters remain in the anuses and bad bacteria parasitic on the waste matters infiltrate into the genital organs, thereby causing the bacterial infections in the reproductive system.

Further, a menstruating woman or a sufferer from piles complains of great unpleasantness and discomfort.

To solve the above problems, a portable bidet has recently been developed and a conventional bidet will be explained hereinafter with reference to FIGs. 1 and 2.

The conventional portable bidet, as shown in FIGs. 1 and 2, is provided with a body 10 which includes a motor pump (not shown) activated by using an electric power of a battery 11, a switch 12 for activating the motor pump, and a nozzle 13 for injecting washing water to the outside by virtue of the actuation of the switch 12, and a washing water case 20 which includes a washing water receiving space 21 defining the body 10 and adapted to contain the washing water in such a manner as to be vertically moved along the body 10, and an inlet 22 formed at one side of the washing water receiving space 21 and adapted to make the washing water flowing into the washing water receiving space 21.

To use the conventional portable bidet constructed above, the washing water case 20 is slidably moved so as to be mounted on one end of the body 10 in a state where the electric power of the battery 11 is supplied, and thereafter the

washing water is poured into the washing water receiving space 21 through the inlet 22.

Next, a user places the nozzle 13 at a position to be washed and then presses the switch 12 to activate the motor pump (not shown).

At this time, the washing water contained in the washing water receiving space 21 of the washing water case 20 is injected to the outside owing to the actuation of the motor pump (not shown), thereby performing a washing process.

Herein, to increase the pressure of the washing water injected to the outside, the portable bidet is used in a state where the switch 12 for increasing the pressure is pressed and the output of the motor pump (not shown) is increased.

The conventional portable bidet is forced to have a large size since the washing water case is slidably moved in the body to form the washing water receiving space.

The conventional portable bidet has another problem in that it is weighty since the motor pump is activated by virtue of the electric power of the battery to automatically inject the washing water and the bidet needs many elements therein.

The conventional portable bidet has a further problem in that it is inconvenient to use it since the motor pump makes a loud noise.

The conventional portable bidet has still another problem in that when the battery is used up quickly, it is difficult to use it, there is required much cost of maintenance, and financial burden is increased.

Meantime, in using the conventional portable bidet constructed as described above, if the user gives an excessive force to rotate the nozzle toward the upper portion of the body in his or her hands, the connecting portion of the nozzle is so weak that it may be broken. Additionally, if the user moves the portable bidet in a state where the nozzle is placed toward the upper portion of the body, the user may touch the nozzle on a part of his or her body and the nozzle

may be broken. Once the nozzle is broken, the compatibility of the nozzle is so poor that the user should buy a new nozzle, thereby increasing financial burden.

Disclosure of Invention Accordingly, the present invention is directed to a portable bidet that substantially obviates one or more problems due to limitations and disadvantages of the related art.

An object of the present invention is to provide a portable bidet which is small in size and light in weight by simplifying the elements mounted therein, easing a noise by manually injecting washing water, achieving an ease utilization by pressing and moving a waterproofing member due to the elasticity of a spring to maintain uniform pressure of washing water injected through an injection nozzle, reduce the cost of maintenance by virtue of manual operation without electric power, and decrease financial burden thanks to a low price.

Another object of the present invention is to provide a nozzle structure of a portable bidet which can be safely used by automatically moving an injection nozzle due to the hydraulic pressure of washing water and injecting the washing water through an injection cap, and prevent the injection nozzle from being damaged and reduce financial burden by using the portable bidet at a position to be washed and preventing the injection nozzle from being touched by a user's body.

Next, a process of assembling the portable bidet constructed as mentioned above will be explained as follows.

First, the first gear 210 in which one side of the pulling member 250 is connected to the first mounting hole 211 is mounted on the first U-shaped mounting groove 115 of the body 110, and both the ends of the first gear 210 are mounted on the rotating groove 117 of the fixing extension 116. Thereafter, the spring 220 is mounted on the spring mounting groove 118 of the body 110.

Further, the other side of the pulling member 250 is coupled to the second mounting hole 243 of the connecting member 240, and the connecting member 240 is put in the connecting piece 232 of the waterproofing member 230. When the connecting member 240 is pressed, the fitting protrusions 242 of the connecting member 240 are fixedly fitted into the fitting holes 233 of the waterproofing member 230.

After the second spring 311 is mounted on the protrusion 114 of the fixed

body 110, the actuation button 310 is slidably moved along the slide groove 113 by virtue of compression force of the second spring 311 when depressing the actuation button 310.

Meantime, the first rotating ring 271 and the second rotating ring 272 are coupled to the rotating member 260 in such a manner that the second gear 262 is inserted into the first rotating ring 271 and the second rotating ring 272, such that the first lug 271 a of the first rotating ring 271 contacts the stopper 264.

The rotating hole 261 of the coupled rotating member 260 is coupled to the coupling protrusion llla of the body 110. At this time, the second gear 262 of the rotating member 260 is engaged with the first gear 210, and the stop protrusion 312 of the actuation button 310 is received in one of the stop recesses 263 of the rotating member 260.

The washer 281 contacts the coupling protrusion 111 a placed on the rotating hole 261 of the rotating member 260 which is coupled to the lower portion of the body 110, and then the washer 281 is coupled to the screw 280, such that the washer 281 closely contacts one end of the rotating hole 261, thereby preventing detachment of the rotating member 260 from the body 110.

The protective cap 290 is mounted on the outside of the rotating member 260.

Furthermore, the rubber ring 322 is mounted on the upper portion of the guide rod 320, and the injection nozzle 330 is slidably fitted into the guide rod 320 through the injection nozzle receiving hole 122 of the coupling member 120. An injection cap 331 is coupled to an end of the injection nozzle 330 and then the coupling member 120 is coupled to the upper portion of the body 110.

At this time, the guide rod 320 fixed to the coupling member 120 passes through the first through-hole 231 of the waterproofing member 230 and the second through-hole 241 of the connecting member 240. The fixing groove 121

of the coupling member 120 receives the fixing section 112 of the body 110 such that the coupling member 120 is coupled to the body 110.

The opening/closing lid 124 is fixed to the opening/closing hole 123 of the coupling member 120, thereby completing the assembling process.

An operation of the portable bidet assembled as above according to the present invention will be explained hereinbelow.

First, if a user wants to use the portable bidet, as shown in FIG. 6a, he or she rotates the protective cap 290 clockwise. At this point, the stop protrusion 312 of the actuation button 310, which is received in the one of the stop recesses 263 of the rotating member 260, is upwardly moved along the upper surface of the stop recesses 263 and then received in one of the stop recesses 263 again.

At the same time when the rotating member 260 is rotated, the second gear 262 is rotated, and the first gear 210 engaged with the second gear 262 is rotated while winding the pulling member 250 fixed to the first mounting hole 211.

When the first gear 210 is rotated while winding the pulling member 250, the connecting member 240 to which the pulling member 250 is connected and the waterproofing member 230 fixed to the connecting member 240 press the first spring 220 while being moved along the guide rod 320. As a result, the connecting piece 232 of the waterproofing member 230 is mounted on the second mounting groove 119.

At this time, when the rotating member 260 is rotated, the stopper 264 is rotated and accordingly the first rotating ring 271 is rotated such that the rotating member 260 is rotated once. When the rotating member 260 is rotated once again, the first lug 271a of the first rotating ring 271 which contacts the stopper 264 is rotated once more along with the second lug 272a of the second rotating ring 272. After the rotating member 260 is rotated twice, the second lug 272a is caught by the fixing jaw 1 lib of the body 110, whereby the rotating member 260

cannot be rotated any more.

The maximum angle of rotation of the rotating member 260 is 720 degrees, namely, two rounds.

Next, the opening/closing lid 124 of the coupling member 120 is separated from the opening/closing hole 123 and then the washing water is poured into the washing water receiving space 111.

To perform a sanitary washing or a partial washing using the washing water contained in the washing water receiving space, as illustrated in FIG. 6b, the injection nozzle 330 is forwardly moved and located at the place to be washed and thereafter the actuation button 310 is forwardly moved along the slide groove 113.

At this point, the actuation button 310 is moved while pressing the second spring 311, and the stop protrusion 312 of the actuation button 310 is separated from the stop recesses 263 of the rotating member 260.

After the stop protrusion 312 is separated from the stop recesses 263, the connecting member 240 and the waterproofing member 230 are moved to the upper end of the washing water receiving space 111 due to the elasticity of the first spring 220. At this time, the hydraulic pressure of the washing water is constantly kept, and the washing water contained in the washing water receiving space 111 is moved to the guide hole 321 of the guide rod 320 such that the washing water is injected to the outside through the injection nozzle 330, thereby enabling to perform the washing process.

In the meanwhile, when the connecting member 240 is upwardly moved, the pulling member 250 wound on the first gear 210 is loosened and upwardly moved along with the connecting member 240. As a result, the first gear 210 is rotated in the opposite direction to the direction in which the first gear 210 is rotated when the pulling member 250 is wound on the first gear 210.

When the first gear 210 is rotated in the opposite direction, the rotating

member 260 is also rotated along with the second gear 262 engaged with the first gear 210 in the opposite direction to the direction in which the rotating member 260 is rotated when the pulling member 250 is wound on the first gear 210.

At this time when the rotating member 260 is rotated, the first lug 271a of the first rotating ring 270 which contacts the stopper 264 is rotated once, namely, 360 degrees in the opposite direction. When the rotating member 260 is rotated once again, the first lug 271a is rotated once again, namely, 720 degrees along with the second lug 272a, such that the second lug 272a is caught by the fixing jaw 111b of the body 110. Thus, the rotating member cannot be rotated any more.

To stop the washing process, the pressure applied to the actuation button 310 is ceased. At this time, the actuation button 310 is downwardly moved along the slide groove 113 due to the elasticity of the second spring 311, and the stop protrusion 312 is received in one of the stop recesses 263 of the rotating member 260, whereby the rotating member 260 cannot be rotated and thus the washing process is stopped.

The sanitary washing and partial washing can be conducted by repeating the above steps. If there is no washing water in the washing water receiving space 111, the portable bidet is used after carrying out the following steps of: separating the opening/closing lid 124 of the coupling member 120 from the opening/closing hole 123, pouring the washing water into the opening/closing hole 123 so as to contain the same in the washing water receiving space 111, and fixing the opening/closing lid 124 to the opening/closing hole 123.

Further, after the portable bidet is used, the injection nozzle 330 is moved to the inside of the guide rod 320, and the portable bidet is put into a bag or a pack to carry.

Further, string or lace W may be attached to the outside of the housing 100 so that the user can hold the string or lace W in hand to carry the portable bidet.

A nozzle structure of the portable bidet according to the present invention will be explained in detail. FIG. 7 is an exploded perspective view of a nozzle according to the present invention, FIG. 8 is a cross-sectional view of the nozzle according to the present invention, and FIG. 9 is a cross-sectional view illustrating a state in which the nozzle is mounted on a portable bidet according to the present invention.

one end thereof, the injection nozzle 1420 being smaller in diameter than the stepped through-hole 1411; an O-ring 1430 fitted around the outer peripheral surface of the injection nozzle 1420 and mounted on the seating member 1414 of the housing 1410; a packing 1440 coupled to one side of the O-ring 1430 and adapted to prevent leakage of the washing water; an injection cap 1450 having a fixing groove 1451 formed at the outer peripheral surface thereof for receiving the end of the injection nozzle 1420 and allowing the fixing protrusion 1423 to be coupled thereto, and an injection hole 1452 for injecting the washing water flowing into the perforated hole 1421 of the injection nozzle 1420 to the outside; and a fixture 1460 coupled to one end of the stepped through-hole 1411.

A process of assembling the nozzle structure constructed as described above will be explained hereinbelow.

First, the injection nozzle 1420 is inserted into the O-ring 1430 and the packing 1440 such that the O-ring 1430 and the packing 1440 are fitted around the outer peripheral surface of the injection nozzle 1420, and the guide protrusion 1423 of the injection nozzle 1420 is placed in the slide groove 1413 of the housing 1410 so that the injection nozzle420 is slidably moved through the stepped through-hole 1411.

At this time, the injection nozzle 1420 that is inserted into the O-ring 1430 and the packing 1440 is guided to the inside of the stepped through-hole 1411, and the 0-ring 1430 and the packing 1440 are mounted on the seating member 1414.

When the housing 1410 having the injection nozzle 1420 formed in the inside thereof contacts an injection nozzle receiving hole 1122 of a coupling member 1120, an end of the injection nozzle 1420 is projected to the outside of the injection nozzle receiving hole 1122, and the packing 1440 fixedly contacts one side of the coupling member 1120.

Furthermore, when the injection cap 1450 is coupled to the end of the

injection nozzle 1420, which is projected beyond the injection nozzle receiving hole 1122 of the coupling member 1120, the fixing groove 1451 of the injection cap 1450 is fitted to the fixing protrusion 1423 of the injection nozzle 1420.

After that, the fixture 1460 is mounted on an end of the stepped through- hole 1411 of the housing 1410 so that the housing can be sealed.

The coupling member 1120 is fixedly placed on the upper end of the housing 1100.

After that, to use the portable bidet with the nozzle structure according to the present invention, as depicted in FIG. 10a, a protective cap 1290 of the compression part 1200 is rotated clockwise. Herein, when a second gear 1262 mounted inside the protective cap 1290 is rotated, a first gear 1210 engaged with the second gear 1262 is rotated while a pulling member 1250 is wound on the first gear 1210.

When the pulling member 1250 is wound on the first gear 1210 in this way, a connecting member 1240 and the waterproofing member 1230 are downwardly moved along the housing 1100 while pressing a first spring 1220 until they cannot be downwardly moved any more.

At this moment, a stop protrusion 1312 of an operating member 1310 is received in one of stop recesses 1263 such that the connecting member 1240 and the waterproofing member 1230 are not moved.

After the compression part 1200 is downwardly moved along the washing water receiving space 1111 of the housing 1100, an opening/closing lid 1124 of the coupling member 1120 is separated from an opening/closing hole 1123, and then washing water is poured into the opening/closing hole 1123 to be contained in the washing water receiving space 1111.

A process of injecting the washing water through the injection cap 1450, as shown in FIG. 10b, is performed by the following steps of: pressing the actuation

button 1310, separating the stop protrusion 1312 from the one of the stop recesses 1263, and allowing the connecting member 1240 and the waterproofing member 1230 to be moved toward the coupling member 1120 due to the elasticity of the first spring 1220.

At this time, as the hydraulic pressure of the washing water is increased, the washing water flows into the two facing inlet holes 1412 and further flows into the perforated hole 1421 of the injection nozzle 1420. The injection nozzle 1420 is forwardly moved along the slide groove 1413 of the housing 1410 due to the hydraulic pressure of the washing water. When the guide protrusion 1422 of the injection nozzle 1420 contacts an end of the 0-ring 1430, the washing water is injected to the outside through the injection hole 1452 of the injection cap 1450, thereby enabling to perform a sanitary washing or a partial washing.

Besides, a user may use the injection nozzle 1420 by forwardly moving the injection nozzle 1420 and placing the injection nozzle at a position to be washed.

Meantime, when the washing process is completed by the above steps, as illustrated in FIG. 10c, the user inwardly moves the injection nozzle 1420 along the slide groove 1413 of the housing 1410.

Industrial Applicability As described above, the portable bidet according to the present invention has advantages in that it is small in size and light in weight because the internal elements are simplified, causes no noise because the washing water is manually injected, is easy to use because the hydraulic pressure of the washing water injected through the injection nozzle is constantly kept by pressing and moving the waterproofing member due to the elasticity of the first spring, and reduces financial burden because maintenance costs are not incurred and the portable bidet

is manually operated.

Furthermore, the nozzle structure according to the present invention has advantages in that it is safely used because an injection nozzle is automatically moved to inject the washing water through the injection cap due to the hydraulic pressure of the washing water, and prevented from being damaged because the portable bidet is used at the place to be washed and the injection nozzle is prevented from being caught on the user's body, thereby reducing financial burden.

While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
