[0029] The technical solution of the present invention will be further explained and illustrated below through specific embodiments. Example 1

[0030] Referring to the attached drawings, a switch valve for a toy water gun includes a switch valve housing 1; the switch valve housing 1 includes a valve core 2, a spring 3, and a rear plug 4; the rear plug 4 is installed on the rear side of the switch valve housing 1, and a water outlet channel 5 is provided inside the switch valve housing 1; the water outlet channel 5 is a notch opened at intervals on the inner wall of the switch valve housing 1; the rear plug 4 forms an installation cavity, and the spring 3 is installed in the installation cavity; the valve core 2 is installed inside the switch valve housing 1; a sealing ring is fitted on the valve core 2; a water outlet 7 and a water inlet 8 are formed on the upper side of the switch valve housing 1; a water gun trigger 9 is in contact with the switch valve housing 1; the valve core 2 is provided with a sealing ring 6.1 and a sealing ring 6.2; and when the trigger 9 is not pulled, the sealing ring 6.2 is on the side of the water outlet channel 5 and in contact with the inner wall of the switch valve housing 1; the water inlet 8 is located between the sealing ring 6.1 and the sealing ring 6.2. Example 2

[0031] Based on the structure of Embodiment 1, the switch valve is connected to the valve body 10; the rear side of the valve body 10 is configured as a water inlet 11, and the front side is connected to a pressurizing device; on the valve body 10, a pipeline is connected downward to form a back pressure port 12, and at another location, a pipeline is connected downward to form a second water inlet 13, and a pipeline is connected on the pipeline formed by the second water inlet 13 to form a pressurized back pressure port 14; two one-way valves are also installed inside the valve body 10, namely one-way valve 17 and one-way valve 2 18. One-way valve 17 is located between the back pressure port 12 pipeline and the second water inlet 13 pipeline; one-way valve 2 18 is located in the second water inlet 13 pipeline.

[0032] The switch valve housing 1 is connected to the valve body 10, and the back pressure port 12 is connected to the outlet 7; the inlet 1 8 is connected to the inlet 2 13.

[0033] The one-way valve includes a valve seat 15, which is cylindrical. Multiple through holes are provided on the valve seat 15, and an umbrella-shaped sealing gasket 16 is installed thereon. A sealing ring is fitted onto the valve seat 15. The umbrella-shaped sealing gasket 16 includes a mounting post and an umbrella gasket, with the mounting post mounted on the valve seat 15. Example 3

[0034] Based on the structure of Embodiment 2, the pressurizing device includes a water pump 19 and a pull rod 20. A sealing ring is installed at the end of the pull rod 20, and the pull rod 20 is installed inside the water pump 19.

[0035] When in use, to draw water, pull the pull rod 20, one-way valve 17 opens, and water is drawn into the water pump 19; push the pull rod 20 back, one-way valve 17 closes and one-way valve 18 opens, and the water flows through the pressure return port 14 of the valve body 10 to the water gun pump body, and also enters between sealing ring 6.1 and sealing ring 6.2 along the water inlet. The water in the water gun pump body and between sealing ring 6.1 and sealing ring 6.2 is high-pressure water, and the water in the water gun pump body is ready to be sprayed; it can be seen that the trigger 9 can be pulled with relatively little force;

[0036] Pulling trigger 9 compresses sealing ring 2 6.2 and spring 3, placing sealing ring 2 6.2 in the water outlet channel 5, allowing water to return from outlet 7 to the water storage tank; other high-pressure water is sprayed out; after releasing trigger 9, the spring causes valve core 2 to return to its original position.
