Description

Technical Field

[0001] This utility model relates to liquid spraying equipment, specifically to a water sprayer. Background Technology

[0002] Handheld water sprayers, or handheld cleaning machines, are equipped with a push-button handle. When the user presses the handle, it pushes against the valve core of the water valve via a push rod, opening the water valve and allowing water to spray from the spray nozzle. A return spring is installed between the handle and the sprayer. When the user presses the handle, the return spring is compressed, accumulating spring potential energy. To maintain the spraying state, the user needs to continuously press the handle. This continuous pressing of the handle can cause user fatigue, making the sprayer inconvenient to use. Furthermore, the push-button handle does not prevent children from operating it, and accidental operation by children could cause discomfort to surrounding objects and people. Utility Model Content

[0003] The technical problem solved by this utility model is that the handheld water sprayer with a push-button handle causes fatigue to the user when the handle is pressed continuously, making the water sprayer inconvenient to use; moreover, the push-button handle does not prevent children from operating it.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a locking device for a handheld water sprayer valve, including a handle hinged to the water sprayer body, a return spring disposed between the handle and the water sprayer body, the free end of the handle abutting against the handle limiting structure of the water sprayer body, the handle having a top pressure part capable of opening the water valve, the handle having a sliding groove, a locking member movably fitted in the sliding groove, the locking member having a locking block, the locking block having a locking port, and the water sprayer body having a locking protrusion; the locking member, which moves along the sliding groove, has its locking block abutting against the locking protrusion, or the locking port of the locking block engaging with the locking protrusion.

[0005] The main body of the water sprayer consists of all parts except the locking device. This part includes the sprayer housing, internal components installed within the housing, and a water inlet connector connected to the bottom of the housing. The internal components include a water valve, piping connecting the water valve to the nozzle, and piping connecting the water valve to the inlet. The water inlet connector connects to the inlet.

[0006] The hinge shaft for the hinged handle is located on the part where the water inlet is located, and the handle limiting structure is located on the part where the spray nozzle is located. The spring seat for mounting the return spring is located on the pipeline between the water valve and the part where the spray nozzle is located. The handle has a corresponding spring seat on its inner side, and the two ends of the return spring are respectively mounted on the two spring seats.

[0007] When the user presses the handle, the return spring is compressed, the locking block moves closer to the locking protrusion, and the locking port aligns vertically with the locking protrusion. The user then slides the locking piece down, engaging the locking port with the locking protrusion. When the user releases the handle, it does not return to its original position; the handle remains pressed down, and the pressing part of the handle holds the push rod, keeping the water valve open. To close the water valve, the user slides the locking piece up, and the return spring returns the handle to its original position, closing the water valve.

[0008] When the handle is not pressed, the user slides the locking mechanism downwards. The end of the locking block near the locking protrusion aligns with the front and back of the locking protrusion. At this point, when the user presses the handle, the locking block abuts against the locking protrusion, preventing the water valve from opening. In this way, the water sprayer can prevent children from using it.

[0009] Alternatively, the opening direction of the locking port is parallel to the displacement direction of the locking element along the slide groove. For example, the opening of the locking port faces downwards, and the displacement direction of the locking element is vertical.

[0010] The handle has a pair of locking limiting structures on its inner side, located on the left and right sides of the slide groove. Each locking element has a pair of hook structures located between the locking limiting structures, with the hooks engaging the inner ends of the locking limiting structures. When the locking element slides in the slide groove, the hooks slide between the locking limiting structures, with the hooks sliding along the inner ends of the locking limiting structures while maintaining their engagement with the inner ends.

[0011] Each locking component's limiting structure has two positioning grooves, and each hook structure has a positioning protrusion. The positioning protrusion, moving with the locking component, can engage with the two positioning grooves respectively. When the locking component slides upward, the positioning protrusion engages with the upper positioning groove, at which point the locking block disengages from the locking protrusion and does not obstruct the handle's pressure. When the locking component slides downward, the positioning protrusion engages with the lower positioning groove, at which point the locking block engages with the locking protrusion, or the locking block obstructs the handle's pressure. The positioning grooves and protrusions allow the locking block to move accurately to the desired position and achieve effective positioning. Simultaneously, they improve the user's feel when manipulating the locking component.

[0012] The slide rail has a recessed structure, and the locking element has a sliding block. The sliding block fits into the recessed structure and can slide along the recessed structure. The recessed structure makes the surface of the handle flat, preventing the locking element from malfunctioning. In addition, the recessed structure can limit the displacement of the locking element.

[0013] A locking protrusion is mounted on a locking protrusion base. A pair of guide structures are located on the inside of the handle. When the handle rotates around the hinge axis, the pair of guide structures move to the left and right sides of the locking protrusion base. The locking protrusion base is located on the pipe between the water valve and the spray nozzle. When the user presses the handle, the cooperation between the pair of guide structures and the locking protrusion base guides the rotation of the handle, preventing it from tilting.

[0014] The locking device of this invention can lock the handle when the user releases it, keeping the water valve continuously open for convenient use. Furthermore, it can lock the handle even when it is not pressed, preventing children from using the sprinkler and improving its safety. Attached Figure Description
