At this time, the elastic component drives the switch handle to be in the closed state. By holding the spray gun body with one hand and pressing the switch handle at the same time to switch it from the closed state to the open state, the thumb is used to turn the rotary dial to rotate it from the release position to the holding position, so that the second limit portion of the rotary dial is aligned with the first limit portion of the switch handle, and the compressive stress on the switch handle is released.

An elastic reset member 5 is arranged between the rotating dial 4 and the spray gun body 1; and the spray gun body 1 is provided with a mounting cavity 11. The elastic reset member 5 always has a movement tendency to drive the rotating dial 4 to reset to the release position. When the rotating dial 4 is in the holding position, the elastic reset member 5 is compressed to accumulate elastic potential energy, and the switch handle 2 is pressed to rotate toward the open state. At this time, the elastic reset member 5 is used to release the elastic potential energy, so that the elastic reset member 5 automatically resets to the release position, and the step of manually resetting the rotating dial 4 can be removed.

[0035] like Figure 3 , Figure 4 As shown, the elastic component 3 includes a spring 31, a pull rod 32, a stopper sleeve 33 fixed to the end of the pull rod 32, and an auxiliary elastic structure 34. The end of the pull rod 32 is provided with a sealing end 35. The auxiliary elastic structure 34 includes a first elastic member group 36 connected to the inner wall of the installation cavity 11 and a second elastic member group 37 connected to the sealing end 35. As the sealing end 35 moves, the second elastic member group 37 continuously resists the first elastic member group 36 and guides the water to flow out. The first elastic member group 36 includes multiple groups of first elastic members 361, which are connected to the inner wall of the installation cavity 11 through a first connecting rod 362, and a resisting ring 363 is installed at the end of the first elastic member 361. A slide groove 38 is provided on one side of the installation cavity 11 close to the sealing end head 35, and the second elastic member group 37 includes a second elastic member 371, a second connecting rod 372 and a third connecting rod 373, the second connecting rod 372 is connected to the outer edge of the sealing end head 35, and a slide rod 374 is installed at the bottom of the slide groove 38, and the second connecting rod 372 and the third connecting rod 373 are respectively connected to the two sides of the slide rod 374; after the first elastic member 361 is bent, it contacts the second elastic member 371 through the contact ring 363.

[0036] like Figure 6 As shown, in one embodiment, the first elastic member 361 is an arched elastic sheet, and the second elastic member 371 adopts a plurality of arched elastic sheets, and the middle part of the elastic sheet is arched inward. The projections of the plurality of first elastic members 361 and the plurality of second elastic members 371 on the radial cross section of the installation cavity are alternately staggered in sequence. In another embodiment, the second elastic member 371 can also adopt a bucket-shaped structure, where the bucket-shaped structure is integrally formed, and the middle part of the second elastic member 371 is arched inward.

[0037] like Figure 4 As shown, the elastic return member 5 is configured as a torsion spring, the spray gun body 1 is provided with an installation cavity 11, the torsion spring is installed in the installation cavity 11, and the spray gun body 1 and the rotating dial 4 are provided with limiting grooves 10 corresponding to the pins 51 at both ends of the torsion spring, the pins at both ends of the torsion spring are limited in the corresponding limiting grooves 10, and the two pins of the torsion spring can only rotate in the limiting grooves 10 corresponding to the spray gun body 1 and the rotating dial 4. When the pin on one side of the limiting groove 10 rotates to the other side position, the rotation angle of the rotating dial 4 can be limited by utilizing the stopping effect of the pin and the side wall of the limiting groove 10. The switch handle 2 is rotatably arranged on the spray gun body 1 through the rotating shaft 12. The switch handle 2 includes a driving end 21 and an execution end 22 located at both ends of the rotating shaft 12. The first limit portion 221 is arranged at the execution end 22. The second limit portion 41 is symmetrically arranged on both sides of the rotating dial 4, and the second limit portion 41 extends toward the execution end 22. Pressing the driving end 21 can drive the execution end 22 at the other end of the rotating shaft to rotate, and the second limit portion 41 is symmetrically arranged; the side parts of the second limit portions 41 on both sides extend outward along the axial direction of the rotating dial 4, and the circular arc transition between the rotating dial 4 and the second limit portion 41 can increase the toggling feel of the second limit portion 41.

[0038] like Figure 4 As shown, the abutting surface between the first limiting portion 221 and the second limiting portion 41 is set as a plane. When the switch handle 2 is in the open state and the rotating dial 4 is rotated to the holding position, the abutting surface of the first limiting portion 221 is in parallel contact with the abutting surface of the second limiting portion 41. The plane setting method can increase the abutting area between the first limiting portion 221 and the second limiting portion 41, thereby improving the abutting stability between the two. The execution end 22 also includes a third limiting portion 222 adjacent to the first limiting portion 221. The abutting surface between the third limiting portion 222 and the rotating dial 4 is set as a plane, and the abutting surface of the first limiting portion 221 is inclined relative to the abutting surface of the third limiting portion 222. When the rotating dial 4 is rotated to the release position, the abutting surface of the third limiting portion 222 is in contact with The abutting surfaces of the rotating dial 4 are in parallel contact. During the rotation of the switch handle 2 relative to the spray gun body 1, the abutting surface of the inclined end face of the third limiting portion 222 can play an effective avoidance effect, and the abutting surface of the third limiting portion 222 is set as a plane. When the rotating dial 4 is rotated to the holding position, the abutting surfaces between the third limiting portion 222 and the rotating dial 4 that are set parallel to each other can be used to press against each other to improve the abutment firmness between the two; the rotating dial 4 is provided with a protruding positioning block 42 between the second limiting portions 41 on both sides, and the switch handle 2 is provided with a positioning groove 220 corresponding to the positioning block 42. When the rotating dial 4 is in the release position, the positioning block 42 is positioned and matched with the positioning groove 220, which can prevent the rotating dial 4 in the release position from accidentally rotating.

[0039] like Figure 5As shown, the spring 31 pushes the pull rod 32 to pull the stop sleeve 33 to move, so that the stop sleeve 33 pushes the execution end 22 toward the rotary dial 4; the execution end 22 is provided with a through hole 223, and the pull rod 32 is movably inserted into the through hole 223. The spring 31 and the stop sleeve 33 are respectively arranged on both sides of the execution end 22, and a movable gap is left between the side wall of the through hole 223 and the pull rod 32. The execution end 22 is symmetrically provided with arc-shaped sliding parts 224 on both sides of the through hole 223. When the switch handle 2 rotates and switches between the holding position and the release position relative to the spray gun body 1, the switch handle 2 slides with the stop sleeve 33 through the arc-shaped sliding part 224, which is conducive to improving the switch handle 2. When the switch handle 2 flips and switches between the holding position and the release position relative to the spray gun body 1, the switch handle 2 can effectively avoid through the movable gap. At the same time, the sliding cooperation between the arc-shaped sliding part 224 and the stop sleeve 33 can effectively prevent the switch handle 2 from getting stuck when rotating.

[0040] When this embodiment is implemented, the second elastic member group 37 of the sealing end 35 moves continuously against the first elastic member group 36 and guides the water to flow out. The first elastic member group 36 and the second elastic member group 37 provide elasticity to limit the movement of the sealing end 35, which can reduce the size of the spring, further make the water flow rate smoother, increase the water flow rate and flow rate, and reduce the resistance to the water flow. The sealing end 35 moves, driving the slide bar 374 to move, and driving the second elastic member 371 to move toward the first elastic member 361. The first elastic member 361 pushes the second elastic member 371 to bend, and the two form a bucket-shaped diversion channel. According to the Bernoulli principle, it increases the water flow rate and flow rate and reduces the resistance to the water flow.

[0041] When the switch handle 2 is in the open state and the rotary dial 4 is rotated to the holding position, the first limit portion 221 and the second limit portion 41 are limited and stopped, and when the rotary dial 4 is rotated to the release position, the first limit portion 221 and the second limit portion 41 are avoided and matched, and the elastic component 3 drives the switch handle 2 to return to the closed state. As the second elastic member group 37 moves with the sealing end 35, it continuously resists the first elastic member group 36 and guides the water to flow out. A rotary dial 4 and a switch handle 2 are rotatably arranged on the spray gun body 1, and the rotary dial 4 is located between the spray gun body 1 and the switch handle 2. In addition, the spray gun body 1 and the switch handle 2 are elastically connected via an elastic component 3. A torsion spring is arranged between the rotary dial 4 and the spray gun body 1. In the initial state, the rotary dial 4 is in a released position relative to the spray gun body 1. At this time, the elastic component 3 drives the switch handle 2 to be in a closed state. The spray gun body 1 is held with one hand and the switch handle 2 is pressed at the same time to switch it from the closed state to the open state. Then, the rotary dial 4 is turned by the thumb to rotate it from the released position to the held position, so that the second limit portion 41 of the rotary dial 4 is aligned with the first limit portion 221 of the switch handle. At this time, the torsion spring is compressed, and then the compressive stress on the switch handle 2 is released. The elastic component 3 drives the switch handle 2 toward the spray gun body 1 by its own elastic force. The switch handle 2 moves to the closed state, so that the first limit portion 221 and the second limit portion 41 are stopped and positioned. At this time, the switch handle 2 cannot continue to move back to the closed state, so that the switch handle 2 is positioned in the open position. When the switch handle 2 needs to be closed, it can be pressed to rotate it toward the open state, and the first limit portion 221 and the second limit portion 41 are separated from each other. The elastic force of the torsion spring in the compressed state is used to drive the rotary dial 4 to automatically rotate from the holding position to the release position. At this time, the first limit portion 221 and the second limit portion 41 are in the avoidance state, and the elastic component 3 can drive the switch handle 2 to reset to the closed state. The rotary dial 4 of the present invention can be controlled by one hand by the thumb, which has the effect of improving the operability through one-hand operation and being able to lock and position the switch handle 2 to keep it in the open state.
