The operation unit 200 is composed of a control body 210, the switch button 250 and the close contact 230.

The adjusting body 210 is rotated by the rear adjusting knob 290 to adjust the amount received and passed from the handle tube pipe 320, the outlet of the handle tube pipe 320 and the control opening and closing 218 The amount of water is adjusted while overlapping as shown in FIG.

The adjusting body 210 is formed by dividing the decompression chamber 280 and the acquisition chamber 270, and a bellows 240 is formed between the decompression chamber 280 and the acquisition chamber 270.

The close contact 230 of the switch button 250 is inserted into the center of the bellows 240 is coupled to the front of the opening and closing port 220, the opening and closing hole 220 is a spring formed inside the rear of the decompression chamber 280 It is fixed by the opening and closing spring 225 fixed to the seating groove 215.

The acquisition room 270 is a place for determining the path of the water to be obtained through the control opening and closing 218 is in communication with the water spray pipe line 140, the bellows 240 is raised to open the access jaw 212, the water is obtained The water is discharged to the water injection pipe line 140 through the chamber 270.

The bellows 240 is composed of a rubber material having an elastic force, the center is formed with a crimping portion (240a) is formed thick, the outer periphery is a '∩' shaped elastic portion 240b, the elastic portion 240b ) And a fixing portion 240c fixed to the inner circumference of the adjusting body 210 is integrally formed.

The crimping part 240a of the bellows 240 has a contact hole through the center (240d) is formed larger than the diameter of the contact table 230, the front is in close contact with the end of the intake jaw (212).

The elastic part 240b is formed with a fine flow path 240e at the upper end of the '∩' shape, and the fine flow path 240e communicates with the control opening and closing 218 to decompress water obtained from the handle pipe line 320. It becomes a passage flowing into the interior of the seal 280.

The switch button 250 is coupled to the close contact 230, the button 257 has a plurality of teeth formed; A guide 253 formed to insert the button 257 and having an operation groove 253b and an insertion hole 253a formed therein; It consists of a button lock 259 is formed with a plurality of teeth and a height adjustment jaw (259a) is formed with a slanted inclined surface (259b) to the rear of the guide 253.

A connection part 340 is formed at an end of the handle part pipe path 320 of the handle part 300, and a hose connector 400 is inserted into the connection part 340, and the hose connector 400 is a connection part 340. It is formed to be in close contact with the inner periphery of the rotation.

In another embodiment of the present invention, as shown in Figures 9 to 12, the switch-type button 250 of the operating unit 200 is removed, and the shape of the decompression chamber 280 is changed to the operating lever 500. It is formed to open and close.

An operating lever 500 is formed at the adjusting knob 290 of the operating unit 200, and the opening of the operating inlet hole 540 in the decompression chamber 280 is opened at the end of the operating lever 500. Opening and closing regulator 520 is composed of a spring 565 and the sealing ball 560 is coupled.

The control chamber 580 of a predetermined space is formed so as to communicate with the operation inlet hole 540 in the decompression chamber 280, the control chamber 580 is in communication with the water spray pipe passage 140.

In the center of the bellows 240 formed between the acquisition chamber 270 and the decompression chamber 280, a hole such as the close contact hole 240d is not formed.

In another embodiment of the present invention, as shown in Figure 13, to change the conduit of the acquisition room 270, the 'b' shaped conduit to the rear of the access jaw 212 is the control opening and closing 218 and In communication with each other, a fine flow path 240e is formed in the center of the bellows 240.

When the size of the micro channel 240e is the same as the size of the close contact hole 240d except for the contact table 230, the micro channel 240e may operate with the smallest force. The force at the time of operation is required to be smaller than the size of the close contact through-hole (240d) except for). Similarly, the relationship between the size of the micro channel 240e and the operation inlet hole 540 is the same.

Hereinafter, the operation method of the water sprayer composed of the embodiments of the present invention will be described.

When the hose is connected to the hose connector 400 of the handle part 300 and water is introduced into the hose, the water passes through the micro-channel 240e through the handle part pipe path 320 and the control opening and closing 218, and then the decompression chamber 280. Flows into.

At this time, the close contact through hole (240d) is blocked by the opening and closing hole 220, when the pressure in the decompression chamber 280 is increased to equal to the pressure of the handle pipe line 320, the bellows 240 is a water supply jaw (212) ), So that no more water enters.

The operation inlet hole 540 of the water sprayer of another embodiment of the present invention serves as a close contact hole 240d.

When operating the operation knob 380 in the above state, the switch type button 250 is pushed to the close contact 230 connected to the opening and closing 220, the water in the decompression chamber 280 is close to the through hole ( A small amount of water flows out through 240d) and the pressure of the water inlet chamber 270 communicating with the handle pipe line 320 becomes relatively greater than the pressure of the decompression chamber 280. It pushes up and flows out to the water injection pipe line 140 beyond the water supply jaw (212).

The actuating lever 500 plays the same role as the actuating handle 380. When the actuating lever 100 is lowered downward, a small amount of water in the decompression chamber 280 enters the actuation inlet hole 540. The bellows 240 is opened by exiting the water and the water on the handle part pipe 320 flows out.

As described above, by rotating the control knob 290 of the water sprayer when the water is sprayed, it is possible to adjust the amount of water sprayed, it can be sprayed by direct or sprinkling by rotating the rotating body 160 of the water sprayer 100 It is.

If, in order to spray water in the form of water, when rotating the rotating body 160 by rotating the rotating body 160, the rear opening hole 146b is closed, the front discharge hole 146a is opened The water is injected through the direct injection hole 145.

If, in order to spray water in the form of water spray, by rotating the rotating body 160 to move the rotating body 160 to the front, the front opening hole 146a is closed, the rear opening hole 146b is a space portion Open to 162 is injected into the water spraying hole 120 of the water.

In order to stop the operation of the water sprayer, by operating the operation knob 380 to close contact 230 connected to the switch-type button 250 to move the opening and closing 220 to the front to block the close-through passage (240d) When the water flows into the decompression chamber 280 through the micro channel 240e, the pressure inside the decompression chamber 280 increases, and if the pressure in the decompression chamber 280 is equal to the pressure of the handle pipe 140. If the same, the bellows 240 closes the entrance jaw 212 to stop the operation.

As the operation knob 380 is operated, when the operation lever 500 of the water sprayer of another embodiment of the present invention is raised upward, the sealing ball 560 closes the operation inlet hole 540 to stop the operation.

As described above, according to the pressure-sensitive water sprayer of the present invention, the following effects are generated.

(1) water is sprayed when the switch button is pressed by forming a switch button in front of the operation unit, and when pressed again, the water can be shut off, which is convenient for use.

(2) It is convenient to form a decompression chamber inside the operating part so that it can be operated with a small force to lower the pressure inside the decompression chamber.
