Water gun with adjustable water flow

Abstract

A water gun for easy water flow adjustment has a main body, a handle, and a tube. A water channel extending to the front end of the tube is formed within the handle. A positioning buckle is pivotally mounted at the top of the tube. A valve stem extends into the tube, with its end protruding outside the tube. A control lever is pivotally mounted behind the handle and connected to the valve stem. The control lever has multiple positioning slots corresponding to the positioning buckle. A nozzle assembly is also assembled at the front end of the tube. A guide hole, gradually widening axially towards the front end of the valve stem, is provided at the front end of the valve stem and is obscured by the nozzle assembly. Moving the valve stem with the control lever changes the position of the obscured guide hole, thereby achieving the effect of water flow adjustment.

Claims

1. A water spray gun for easy adjustment of water flow, comprising: a body having a handle and a tube body disposed at the top of the handle, wherein a water channel is provided inside the handle and extends to the front end of the tube body, and a through hole communicating with the water channel is provided at the rear end of the tube body; a positioning buckle pivotally disposed at the top of the tube body; a valve stem extending into the tube body and having its end extending outside the through hole, and a return spring sleeved on the valve stem; a control lever pivotally disposed at the rear side of the handle, the control lever being connected to the end of the valve stem and being pulled by the control lever to move within the tube body, the control lever also having a plurality of positioning grooves corresponding to the positioning buckle, wherein the control lever is fixed in a corresponding pivoting position by the positioning buckle pivoting to engage with one of the positioning grooves; A nozzle assembly includes a nozzle with an internal hollow flow channel and an adjusting cap. The nozzle is connected to the front end of a pipe body, and a valve stem is inserted into the water inlet of the nozzle to open and close the water channel. The adjusting cap is screwed onto the water outlet of the nozzle to adjust the water pattern. The valve stem has an axial opening at its front end facing the nozzle cavity, and at least one guide hole is radially provided through it, which is blocked by the water inlet end of the nozzle. The guide hole gradually expands along the axial direction of the valve stem towards the front end of the valve stem to form a narrow end and a wide end close to the front end of the valve stem. By pressing the control lever, the valve stem is moved in the direction of the control lever, changing the position where the guide hole is blocked, thereby adjusting the water flow rate from the water channel into the cavity.

2. The water spray gun as described in claim 1, wherein, The nozzle is inserted into and screwed to the front end of the pipe body with its water inlet end. The water inlet end has a large diameter section and a small diameter section for connecting water channels. The front end of the valve stem passes through the large diameter section and is inserted into the small diameter section, thereby shielding the guide hole through the small diameter section.

3. The water gun as described in claim 2, which allows for easy adjustment of the water flow, wherein, The valve stem is also fitted with a water-stop ring behind the guide hole to seal the small diameter section.

4. The water gun as described in claim 2, which allows for easy adjustment of the water flow, wherein, The valve stem has a plurality of guide blocks protruding at intervals on its outer peripheral wall, which are used to guide the movement direction of the valve stem in conjunction with the large diameter section.

5. A water spray gun as described in claim 4, wherein, A groove is recessed at the connection between the water channel inside the pipe and the through hole. A sealing ring is fitted onto the valve stem and placed in the groove to seal the through hole. The return spring presses against the sealing ring with one end and against the guide blocks with the other end.

6. A water gun as described in claim 1, wherein, The control lever has a joint portion facing the rear end of the tube body. The joint portion is also provided with a mounting hole for the valve stem to pass through. The end of the valve stem passes through the mounting hole and is connected to a limiting ring, so that its end is connected to the control lever. Two outwardly protruding ears are symmetrically provided on both sides of the mounting hole. The two ears abut against the limiting ring as the control lever pivots.

7. A water spray gun as described in claim 6, wherein, The joint has a protrusion above the mounting hole that protrudes toward the rear end of the tube body, and a plurality of positioning grooves are provided on the side of the protrusion opposite to the rear end of the tube body.

8. A water gun as described in claim 6, wherein, The joint is also fitted with a cap to seal the end of the valve stem.

9. A water gun as described in claim 1, wherein, The positioning buckle is curved and has two symmetrical legs. The two legs are pivotally connected to the two sides of the tube body. The positioning buckle has a locking tooth facing the positioning grooves. The positioning buckle is swung to the locking tooth and engages with one of the positioning grooves to fix the control lever.
