The hose 13 may be connected to the lower body 410 of the handle 400 fixed as described above.

The following describes the operation process of the subject innovation combined as described above.

First, in the state where the water supplied through the water supply control valve 11 by adjusting the water supply control unit 12 is located inside the channel 411 of the lower body 410 through the hose 13, the user uses water. To press, press the pressing button 613c of the water supply member 630 as shown in Figure 8a.

At this time, the pressing force for pressing the pressing button 613c is higher than the water pressure of the water stored in the water supply piston 631, while pushing the end of the "U" shaped piston packing 612 in one direction while pressing the piston spring 620. Done.

In addition, as the inner surface of the water supply piston 631 presses the end of the "U" -shaped piston packing 612 as described above, the end of the "U" -shaped piston packing 612 does not endure hydraulic pressure and is folded. The water channel 421 of the upper body 420 is moved to the water stored in the water supply piston 631 through the portion.

When the water supply piston 631 moves in one direction as described above, the guide rib 631b of the water supply piston 631 pressurizes the pressure rod 531c of the valve rod 531 to raise the height of the guide rib 631b. As much as the valve rod 531 moves downward while pressing the valve spring 520.

When the valve disc 532 is moved downward by the pressure of the valve rod 531, the "U" shaped disk packing 534 is moved in close contact with the inner surface of the seating space 511, the valve body 510 Water stored in the seating space 511 of the) is discharged to the water channel 411 of the lower body 410 through the through-hole 512.

In addition, when the valve disc 532 moves downward according to the pressure of the valve rod 531, the disk pad packing 533 in close contact with the pressing protrusion 542 of the cover 540 is separated from the pressing protrusion 542. At the same time, water supplied to the water channel 411 of the lower body 410 flows into the inlet hole 514 of the valve body 510, and the introduced water flows between the guide ribs 531b of the valve rod 531. It is supplied to the channel 421 of the upper body 420 via.

The water thus supplied is injected to the outside through the injection hole 712 of the injection member 710, and the water to be sprayed is used for a predetermined time (for example, 30 seconds) by the user.

When water is used as described above, a part of the water supplied to the water channel 421 of the upper body 420 flows into the water supply piston 631 through the inlet hole 631a of the water supply piston 631, and is introduced therein. The water supply piston 631 is returned to its original state by the hydraulic pressure and the restoring force of the piston spring 620.

At this time, the valve rod 531 pressurized by the guide rib 631b of the water supply piston 631 is formed by the hydraulic pressure of the water flowing into the through hole 512 of the valve body 510 and the restoring force of the valve spring 520. Attempts to move to, along the inclined surface of the water supply piston 631 is moved upward.

In this way, the guide member 530 is moved upward by the hydraulic pressure of the water flowing into the through hole 512 of the valve body 510 and the restoring force of the valve spring 520, so that the disk pad packing 533 of the cover 540 When in close contact with the pressing protrusion 542, the water supplied through the water channel 411 of the lower body 410 is blocked.

Therefore, while repeating the above process, the user can use the water injected through the injection unit 700 for a predetermined time.

Here, the time for using the water injected into the injection member 710 is different depending on the size of the inlet hole 631a of the water supply piston 631, but in general, from 5 seconds to 30 seconds at least. I can regulate it.

In addition, as the user presses the water supply member 630 of the operation unit 600 to move the guide member 530 downward, the water supplied to the water channel 411 of the lower body 410 is the upper body 420 When the use of water is completed while using the water sprayed to the injection unit 700 through the water channel 421 of the, as shown in Figure 8b, the user is to put the water button cap packing 615 of the index member 610 By pressing, the water discharge button 614 is moved in the other direction.

At this time, the water button 614 presses the water supply piston 631 in the other direction through the piston spring 620, the water button 614 is separated from the end of the through hole (611a) of the fixed piston 611.

As described above, when the water button 614 is separated from the end of the through hole 611a, a part of the water supplied to the channel 421 of the upper body 420 is fixed through the inlet hole 611b of the fixing piston 611. Since the piston 611 flows into the through hole 611a, the guide member 530 moves upward as the water supply piston 631 is returned to its original state by the water pressure of the introduced water and the restoring force of the piston spring 620. By moving to pressurizing the pressing protrusion 542 of the cover 540 is to block the supply of water can not be used.

Here, it is possible to adjust the time to block the water supplied according to the size of the inlet hole (611b) of the fixed piston 611, generally 2 to 3 seconds is most suitable.

As described above, the present invention separates the body of the shower into the lower part and the upper part, and the inside of the lower body is equipped with a control unit for controlling the supply of water, the inside of the upper body to assemble by mounting the operation unit for operating the control unit respectively As a result, the production process is simplified to improve productivity, and the water injected through the shower is sprayed for a certain time and automatically shut off, thereby reducing the waste of water and reducing the cost of fuel, thereby improving economics.
