[0031] The technical solutions of various embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments described in this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] An embodiment of this utility model provides a switch adjustment mechanism for a thumb gun, such as... Figure 1-7The water gun comprises a gun body, a nozzle assembly, and a switch assembly. The gun body includes a water gun housing 200 and a water channel 800, with the front end of the housing 200 engaging with the nozzle assembly. The switch assembly is rotatably mounted on the housing 200. The water channel 800 connects to the interior of the gun body and is used to deliver water to the nozzle assembly. Specifically, the front end of the water channel 800 is threadedly connected to an elbow 300, the elbow 300 having an arc-shaped aperture, and the front end of the elbow 300 is snapped and fixed to the nozzle assembly. The bottom of the water channel 800 also has a connecting port for connecting to a water pipe outlet.

[0033] The nozzle assembly includes a nozzle 100 and a connector 110. The nozzle 100 is snapped and fixed to the front end of the connector 110, and the connector 110 is snapped and fixed inside the elbow 300. The nozzle of the nozzle 100 is in communication with the connector 110.

[0034] The switch assembly includes a switch adjustment mechanism and a seal, such as Figure 8-10 The aforementioned switch adjustment mechanism is used to control the flow of water within the water gun, thereby controlling the on / off state of the water flow. The switch adjustment mechanism includes a switch gear 500, a push-button rack 410, a synchronization gear 510, and a push button 400. The switch gear 500 is connected to a rotating shaft, which is rotatably fitted onto the gun body and perpendicularly passes through the water passage within the gun body. An adjustment protrusion is provided on the rotating shaft, and a water-sealing gasket 700 is engaged within the adjustment protrusion. The water-sealing gasket 700 forms a rotating opening and closing state with the cross-section of the water passage within the gun body. Specifically, the water-sealing gasket 700 forms a rotational obstruction at its connection point with the through-hole within the elbow 300. Rotary holes are provided on both side walls of the elbow 300, and rotating annular grooves are provided on both sides of the rotating shaft, which is rotatably fitted onto the elbow 300.

[0035] The sealing element is an O-ring 600, and an O-ring 600 is provided at the contact point between the rotating shaft and the rotating hole to ensure water tightness.

[0036] The push button rack 410 is arc-shaped and conforms to the elbow 300. Two rows of push button teeth are symmetrically arranged on the push button rack 410, forming an arc-shaped structure similar to a partial toothed ring. The push button rack 410 meshes with the switch gear 500. A protrusion is formed at the upper bend of the water gun housing 200, and this protrusion has a curved hole that matches the arc of the push button rack 410. A buckle is provided at the bottom of the push button 400, and a locking interface is provided on the back of the push button rack 410. The push button 400 is locked to the back of the push button rack 410, assisting in sliding the push button rack 410 and facilitating the identification of the water circuit switch status within the gun body through its relative position to the sliding groove.

[0037] A synchronizing gear 510 is provided on the side of the rotating shaft away from the switching gear 500. The synchronizing gear 510 is correspondingly provided to the switching gear 500, and the synchronizing gear 510 is synchronously engaged with the push button rack 410.

[0038] During use, the bottom of the gun body is connected to a water pipe. By pushing the push button 400 and the push button rack 410 relative to the gun body, the push button rack 410 engages and transmits power to the switch gear 500. The switch gear 500 coaxially drives the water-sealing gasket 700 to rotate, causing the water-sealing gasket 700 to rotate and connect the water passage inside the gun body, thus ensuring unobstructed water flow. Figure 6 .

[0039] After use, push the push button rack 410 back to reset it, so that the water-sealing gasket 700 re-seals the water passage.

[0040] This solution controls a large-diameter local gear ring to drive a small gear, and forms a force-saving structure by setting the transmission ratio. When in use, the push button rack 410 is actively adjusted to move a small angle, and the small gear meshing with it can rotate a large range of angles. The switch adjustment effect is intuitive and easy to adjust. The push button rack 410 is arc-shaped, and the pushing method conforms to human operating habits, making it convenient to operate. Compared with the existing adjustment structure, it saves the space required for the control components.
