DETAILED DESCRIPTION OF THE INVENTION

[0017] The present invention will be further described below with reference to the drawings and specific embodiments, but it is not limited to the present invention.

[0018] As Figure 1 and Figure 2 shown, a labor-saving high-pressure water gun of a preferred embodiment is shown, including:

[0019] Gun body 1, return spring 2, trigger 3, pulley 20, gun valve push rod 4, gun valve body, water inlet pipe 5 and water outlet pipe 6. The trigger 3 is hinged inside the gun body 1. One end of the return spring 2 is installed on the inner wall of the gun body 1, and the other end of the return spring 2 is connected to one side of the trigger 3. The pulley 20 is rotatably installed on the trigger 3. The gun valve push rod 4 is hinged inside the gun body 1. The pulley 20 slides and abuts against the lower side of one end of the gun valve push rod 4. The water inlet pipe 5 and the water outlet pipe 6 are both installed on the gun body 1. One end of the water outlet pipe 6 is connected to one side of the gun valve body, and the upper end of the water inlet pipe 5 is connected to the lower end of the gun valve body. The lower side of the other end of the gun valve push rod 4 abuts against the gun valve body and drives the gun valve body to connect or close the water inlet pipe 5 and the water outlet pipe 6.

[0020] During actual use, the user presses the other side of the trigger 3. One side of the trigger 3 squeezes the return spring 2 and at the same time drives the pulley 20 to move away from the water outlet pipe 6. As a result, one end of the gun valve push rod 4 moves upward in the vertical direction. At this time, the other end of the gun valve push rod 4 moves downward in the vertical direction and squeezes the gun valve body to open the gun valve body, enabling the water inlet pipe 5 and the water outlet pipe 6 to communicate. When the user stops pressing the trigger 3, the return spring 2 extends, driving the trigger 3 to rotate. At this time, the pulley 20 moves toward the water outlet pipe 6, and at the same time the gun valve body resets, closing the water inlet pipe 5 and the water outlet pipe 6. Further, the angle between the length direction of the trigger 3 and the length direction of the gun valve push rod 4 is between 80° and 90°, making it more labor-saving for the user to press the trigger 3.

[0021] Further, as a preferred embodiment, the gun body 1 includes: a main body portion 7 and a holding portion 8. One end of the main body portion 7 is connected to one end of the holding portion 8. The water inlet pipe 5, the water outlet pipe 6, and the gun valve push rod 4 are all installed inside the main body portion 7. One end of the main body portion 7 is provided with a water outlet, and the other end of the water outlet pipe 6 extends out of the water outlet. The lower side of the main body portion 7 is provided with a water inlet, and the lower end of the water inlet pipe 5 extends out of the water inlet. One side of the holding portion 8 is provided with a pressing opening, and the trigger 3 is movably arranged inside the pressing opening. Further, during actual use, the lower end of the trigger 3 is hinged to the lower end inside the holding portion 8, and the other end of the gun valve push rod 4 is hinged inside the main body portion 7. When pressing the other side of the trigger 3, the trigger 3 rotates along the hinge, causing the upper end of the trigger 3 to rotate away from the water outlet pipe 6, thereby driving the pulley 20 away from the water outlet pipe 6, making one end of the gun valve push rod 4 move upward in the vertical direction. At this time, the other end of the gun valve push rod 4 moves downward in the vertical direction and squeezes the gun valve body to open the gun valve body.

[0022] Further, as a preferred embodiment, the gun valve body includes: a valve body 9, a valve spring 10, a valve rod 11, a sealing ring 12, and a sphere 13. The valve body 9 is installed in the main body portion 7. One end of the water outlet pipe 6 is connected to one side of the valve body 9, and the upper end of the water inlet pipe 5 is connected to the lower end of the valve body 9. A chamber 14 is formed in the valve body 9. The valve rod 11 is movably installed in the chamber 14. The lower side of the other end of the gun valve push rod 4 abuts against the upper end of the valve rod 11. The outer wall of the sphere 13 is installed at the lower end of the valve rod 11. The valve spring 10 and the sealing ring 12 are both installed in the chamber 14. The sphere 13 is arranged below the sealing ring 12, and the valve spring 10 is arranged below the sphere 13. The sphere 13 can movably control the opening or closing of the chamber 14. Further, during actual use, when the trigger 3 is pressed, one end of the gun valve push rod 4 moves upward in the vertical direction. At this time, the other end of the gun valve push rod 4 moves downward in the vertical direction and presses the valve rod 11. The valve rod 11 moves downward in the vertical direction, thereby driving the sphere 13 to compress the valve spring 10. At this time, the sphere 13 opens the chamber 14, so that the water outlet pipe 6 is communicated with the water inlet pipe 5. When the trigger 3 is no longer pressed, the valve spring 10 extends, driving the sphere 13 to move upward in the vertical direction, closing the chamber 14, and at the same time driving the valve rod 11 to move upward in the vertical direction. At this time, the other end of the gun valve push rod 4 moves upward in the vertical direction, and further causes one end of the gun valve push rod 4 to move downward in the vertical direction, and the return spring 2 extends, causing the pulley 20 to move in the direction close to the water outlet pipe 6. The pulley 20 loses the restriction on the gun valve push rod 4, and finally resets to close the water gun.

[0023] Further, as a preferred embodiment, the chamber 14 includes a first channel portion 15 and a second channel portion 16 that are connected in sequence from top to bottom. The valve rod 11 is slidably installed in the first channel portion 15 and the second channel portion 16. The sphere 13, the sealing ring 12, and the valve spring 10 are all installed in the second channel portion 16. The sealing ring 12 is arranged at the connection of the first channel portion 15 and the second channel portion 16. The inner diameter of the first channel portion 15 is smaller than the diameter of the sphere 13, and the diameter of the sphere 13 is not greater than the inner diameter of the second channel portion 16. The sphere 13 can operably open or close the first channel portion 15. Further, during actual use, when the user presses the trigger 3, it drives the gun valve push rod 4 to rotate, so that the valve rod 11 moves downward in the vertical direction, and further drives the outer wall of the sphere 13 not to contact the sealing ring 12, thereby opening the valve body 9. When the user stops pressing the trigger 3, the valve spring 10 extends so that the outer wall of the sphere 13 abuts against the sealing ring 12 to close the first channel portion 15, thereby closing the valve body 9.

[0024] Further, as a preferred embodiment, a water outlet hole is provided on the side wall of the valve body 9, the water outlet hole is communicated with the first channel portion 15, and one end of the water outlet pipe 6 is communicated with the water outlet hole.

[0025] Further, as a preferred embodiment, the included angle between the length direction of the trigger 3 and the length direction of the gun valve push rod 4 is 80° to 90°. Further, the included angle between the length direction of the trigger 3 and the length direction of the gun valve push rod 4 is between 80° and 90°, so that it is more labor-saving for the user to press the trigger 3.

[0026] Further, as a preferred embodiment, it further includes: a noise reduction soft rubber 17, which is installed in the main body portion 7, and the lower side of the gun valve push rod 4 is operably abutted against the outer wall of the noise reduction soft rubber 17. Further, during actual use, the noise reduction soft rubber 17 prevents the gun valve push rod 4 from colliding with the inner wall of the main body portion 7, reduces noise, protects the gun valve push rod 4, and at the same time, the noise reduction soft rubber 17 is made of an elastic material, such as rubber, which facilitates the reset of the gun valve push rod 4.

[0027] Further, as a preferred embodiment, one end of the gun valve push rod 4 has a bent portion 18, the outer edge of the bent portion 18 is arc-shaped, and the outer wall of the pulley 20 abuts against the outer edge of the bent portion 18.
