[0031] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] Example

[0033] The specific implementation of the utility model is as follows Figures 1 to 7 As shown, a cleaning water gun comprises a housing 1, which includes a body 12, a handle 11, and a handguard 13. Handle 11 houses a water inlet pipe 4, while body 12 houses an on / off valve 2 and a water outlet pipe 5. A water pattern adjustment nozzle 6 is located at the front end of body 12. The inlet pipe 4, on / off valve 2, water outlet pipe 5, and water pattern adjustment nozzle 6 are sequentially connected. A trigger 3 is hingedly connected to body 12 and is linked to on / off valve 2. A trigger normally-open fixing structure and a trigger normally-closed fixing structure are located between handguard 13 and trigger 3.

[0034] The trigger normally open fixing structure includes a first protrusion 15 and a first rotating clamp 32. The first protrusion 15 is fixedly arranged on the inner side of the upper part of the hand guard 13. One end of the first rotating clamp 32 is rotatably connected to the upper part of the trigger 3, and the other end of the first rotating clamp 32 is engaged with the first protrusion 15.

[0035] The trigger normally closed fixing structure includes a second protrusion 14 and a second rotating clamp 33. The second protrusion 14 is fixedly arranged on the inner side of the lower portion of the hand guard 13. One end of the second rotating clamp 33 is rotatably connected to the lower portion of the trigger 3 via a first rotating shaft 331, and the other end of the second rotating clamp 33 is engaged with the second protrusion 14.

[0036] A groove 34 is provided on the rear side of the trigger 3 , and the second rotating clamp 33 is embedded in the groove 34 when in the folded state.

[0037] The switch valve 2 includes a valve core 22 and a valve seat 21 that slide together. The valve seat 21 is provided with a first channel 211, a first inner cavity 212, and a second channel 213 that are connected in sequence. One end of the valve core 22 extends from the connection between the first inner cavity 212 and the second channel 213 into the first inner cavity 212 and is connected to the valve core pressure cover 23. The other end of the valve core 22 extends out of the valve seat 21 and is linked to the trigger 3. A first sealing ring 24 is provided between the valve core pressure cover 23 and the output port of the first inner cavity 212. In this embodiment, the first sealing ring 24 is installed on the valve core pressure cover 23, and the first sealing ring 24 contacts and cooperates with the outer edge of the output port of the first inner cavity 212. A return spring 25 is also provided in the first inner cavity 212. The return spring 25 and the first sealing ring 24 are respectively located on both sides of the valve core pressure cover 23, and the return spring 25 is in a compressed state. The valve core 22 is provided with an opening communicating with the first inner cavity 212, and a cover 26 is installed at the opening, which is pressed on one end of the return spring 25. After opening the cover 26, the return spring 25, the valve core 21 and the valve core gland 23 can be removed for easy maintenance.

[0038] In this embodiment, a pressure-applying portion 35 is provided on the trigger 3 , and the pressure-applying portion 35 contacts and cooperates with an end of the valve core 22 extending out of the valve seat 21 .

[0039] During use, the person holds the handle 11 with his hand and pulls the trigger 3 with his finger. The trigger 3 applies pressure to the valve core 22 and overcomes the elastic force of the return spring 25. The valve core 22 moves relative to the valve seat 21 along its length direction, and the first sealing ring 24 leaves the output port of the first inner cavity 212. At this time, the high-pressure water passes through the water inlet pipe 4, the switch valve 2, the water outlet pipe 5 in sequence and is sprayed out from the water outlet mode adjustment nozzle 6.

[0040] When it is necessary to use the trigger normally open fixing structure, first press the trigger 3 toward the handle 11 with your finger, and then fix the relative position of the trigger 3 and the handle 11 by allowing one end of the first rotating clamping member 32 to engage with the first protrusion 15, so that the switch valve 2 is in a continuously open state. At this time, the water outlet mode of the cleaning water gun adjusts the nozzle 6 to continuously spray water.

[0041] When the trigger normally closed fixing structure is needed, the second rotating clamping member 33 is folded downward relative to the trigger 3 so that one end of the second rotating clamping member 33 is engaged with the second protrusion 14. At this time, even if pressure is applied to the trigger 3 with a finger, the trigger 3 cannot be pulled, thereby preventing the trigger 3 from being accidentally touched and causing the cleaning water gun to spray water accidentally, making it safer to use.

[0042] The input end of the water inlet pipe 4 is equipped with a water supply pipe connector 41, located on the outside of the bottom of the handle 11, for easy connection to an external water supply pipe. The output end of the water inlet pipe 4 is threadedly connected to the first channel 211 of the valve seat 21, and the second channel 213 of the valve seat 21 is threadedly connected to the input end of the water output mode adjustment nozzle 6.

[0043] The water pattern adjustment nozzle 6 includes an inner cylinder 61, the rear end of which is connected to the water outlet pipe 5 via a connecting sleeve 65. A water outlet hole 611 is provided on the front sidewall of the inner cylinder 61. A conical surface 612 and a T-shaped block 613 are sequentially connected to the front end of the inner cylinder 61. An adjustment cap 62 is provided on the outer side of the front end of the inner cylinder 61. The adjustment cap 62 and the inner cylinder 61 are threadedly connected via a threaded structure 64. The inside of the adjustment cap 62 is provided with a second inner cavity 621, a conical channel 622, a third channel 623, and a conical water outlet 624, which are sequentially connected. The conical surface 612 of the inner cylinder 61 is adapted to fit the conical channel 622 of the adjustment cap 62, and the T-shaped block 613 passes through the third channel 623. When the water impacts the T-shaped block 613, it tends to diffuse outward.

[0044] The water flow mode can be changed by operating the water flow mode adjustment nozzle. By turning the adjustment cap 62, the distance between the conical surface 612 of the inner cylinder 61 and the conical channel 622 of the adjustment cap 62 is changed to adjust the water flow rate. At the same time, by changing the position of the head of the T-shaped block 613 within the third channel 623 and the conical water outlet 624, the diffusion angle of the water flow after impacting the T-shaped block 613 is adjusted, thereby achieving a variety of water flow modes.

[0045] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
