Description

Technical Field

[0001] This utility model relates to the field of water spray gun technology, and in particular to a water spray gun that is easy to adjust the water flow. Background Technology

[0002] In daily life, water guns are widely used as essential tools for cleaning, gardening, and recreation. Traditional water gun designs typically use a nut to control the water flow and on / off state. Users need to manually rotate the nut to adjust to the appropriate water flow rate. This process is not only time-consuming and laborious, but frequent adjustments can also lead to nut wear or loss of precision, affecting user experience and product lifespan. Furthermore, in certain specialized applications, such as rapid-response cleaning operations, the traditional nut adjustment method is inconvenient. For tasks requiring quick changes in water flow intensity, each adjustment represents additional time costs and may cause the optimal working time to be missed. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a water spray gun that is easy to adjust the water flow, which has the characteristics of convenient and quick adjustment of the water flow size.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] A water spray gun that facilitates water flow adjustment includes a gun body, a rear trigger located at the rear of the gun body, a water outlet chamber formed within the gun body, and a valve stem capable of adjusting the flow rate of the water outlet chamber located within the rear trigger.

[0006] The rear trigger is hinged to the rear side of the gun body. Pressing and rotating the rear trigger can pull the valve rod to control the flow rate of water in the outlet chamber. The rear trigger is provided with an adjustment component, and the rear side of the gun body is provided with a fastening component for abutting against the adjustment component to lock the rear trigger.

[0007] The front side of the adjusting member forms several steps from top to bottom, and the rear side of the fastening member forms a boss. When the rear trigger rotates to different positions, the boss can abut and fix in the corresponding step to lock the rear trigger.

[0008] The step includes a closed groove and several adjustable steps. When the boss is engaged with the closed groove, the valve stem can block the water outlet chamber, and the water gun is in a closed state. When the boss abuts against different adjustable steps, the valve stem opens the water outlet chamber to different degrees, and the water flow rate of the water gun is different.

[0009] The closed groove includes an upper abutting plane located at the upper edge of the groove and a lower abutting slope located at the lower edge of the groove, and the adjusting step is located below the lower abutting slope.

[0010] The boss includes an upper platform, and the adjusting step includes a first abutting surface for abutting against the upper platform and a second abutting surface for abutting against the rear side of the boss.

[0011] The gun body includes a gun body, a handle connected to the gun body, and a nozzle connected to the front side of the gun body;

[0012] The water outlet chamber is located inside the gun body, and a water outlet hole is formed at the front end of the water outlet chamber that communicates with the nozzle. The valve stem includes a valve head at the front end that can move in the front-back direction within the water outlet hole. The valve head includes a first flow port opened on the side in the front-back direction and a second flow port opened on the front end face that communicates with the first flow port. The degree of extension and retraction of the valve head in the front-back direction within the water outlet hole controls the flow rate of water flowing from the water outlet chamber into the water outlet hole.

[0013] The rear-press trigger includes a trigger head and a lever connected below the trigger head. A hinge point is provided between the trigger head and the lever to be hinged to the rear end of the gun body. The rear end of the valve stem is connected inside the trigger head. When the lever is pressed down, the trigger head can pull the valve stem to move backward.

[0014] The adjusting component is located on the front side of the upper end of the trigger head, and a torsion spring is provided at the hinge point. When the trigger is not subjected to external force, the torsion spring pulls the trigger head to rotate forward, causing the adjusting component to engage with the fastening component.

[0015] The water outlet is a cylindrical hole, the valve head is cylindrical, and an elastic sealing ring is provided on the rear side of the valve head.

[0016] The fastener is semi-circular and hinged to the gun body. A raised actuating ring is formed on the outer surface of the fastener.

[0017] The handle is provided with an inlet chamber that communicates with the outlet chamber.

[0018] The beneficial effects of this utility model are:

[0019] 1. It provides an intuitive and easy-to-use adjustment mechanism. Through the interaction between the adjustment piece on the rear trigger and the fastening piece on the gun body, multi-level precise flow control is achieved. The different adjustment steps allow users to select the most suitable water output according to specific needs, ensuring operational flexibility and accuracy.

[0020] 2. The water gun provided by this utility model abandons the traditional nut adjustment mechanism, instead utilizing the cooperation between a practical fastener and an adjusting step to achieve rapid and precise water flow adjustment. The water flow level can be selected with simple operation, eliminating the need for cumbersome twisting motions, greatly improving convenience and efficiency. Simultaneously, this design ensures good sealing performance, guaranteeing a stable water output at different settings, adapting to the needs of various working environments, and thus providing users with a more intelligent, efficient, and safe user experience.

[0027] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0028] Reference Figure 1 , Figure 2 This utility model proposes a water spray gun that is easy to adjust the water flow, including a gun body 1, a rear trigger 2 set at the rear side of the gun body 1, a water outlet chamber 110 formed inside the gun body 1, and a valve stem 22 that can adjust the flow rate of the water outlet chamber 110 inside the rear trigger 2.

[0029] The rear trigger 2 is hinged to the rear side of the gun body 1. Pressing and rotating the rear trigger 2 can pull the valve rod 22 to control the flow rate of water in the outlet chamber 110. The rear trigger 2 is provided with an adjusting part 31, and the rear side of the gun body 1 is provided with a fastening part 30 for abutting against the adjusting part 31 to lock the rear trigger 2.

[0030] Reference Figure 2 , Figure 3 The front side of the adjusting member 31 forms several steps from top to bottom, and the rear side of the fastening member 30 forms a boss 301. When the rear trigger 2 rotates to different positions, the boss 301 can abut and fix in the corresponding step to lock the rear trigger 2.

[0031] Reference Figure 3 , Figure 5 The step includes a closed groove 310 and several adjusting steps 311. When the boss 301 is engaged with the closed groove 310, the valve stem 22 can block the water outlet chamber 110, and the water spray gun is in the closed state. When the boss 301 abuts against different adjusting steps 311, the valve stem 22 opens the water outlet chamber 110 to different degrees, and the water flow rate of the water spray gun is different.

[0032] The closed groove 310 includes an upper abutting plane 3100 located on the upper side of the groove and a lower abutting slope 3101 located on the lower side of the groove, and the adjusting step 311 is disposed below the lower abutting slope 3101.

[0033] Specifically, when the boss 301 engages with the closed groove 310, the upper abutting plane 3100 abuts against the upper platform 3010, preventing the boss 301 from disengaging from the closed groove 310. When the adjusting member 31 rotates backward, the lower abutting inclined surface 3101 makes it easier for the boss 301 to disengage from the closed groove 310.

[0034] The boss 301 includes an upper platform 3010, and the adjusting step 311 includes a first abutting surface 3111 for abutting against the upper platform 3010 and a second abutting surface 3110 for abutting against the rear side of the boss 301.

[0035] The adjusting member 31 is located on the front side of the upper end of the trigger head 20, and a torsion spring is provided at the hinge point 200. When the trigger 2 is not subjected to external force, the torsion spring pulls the trigger head 20 to rotate forward, so that the adjusting member 31 is engaged with the fastening member 30.

[0036] The fastening element 30 is semi-circular and is hinged to the gun body 1. A raised actuating ring 300 is formed on the outer surface of the fastening element 30.

[0037] Furthermore, when the water gun needs to be turned on, the pressure plate 2 is pressed down, the valve stem 2 controls the flow of water in the outlet chamber 110, the adjusting member 31 rotates backward, and the closing groove 310 gradually disengages from the lower abutment inclined surface 3101 from the boss 301. At this time, the actuating ring 300 is moved to select different adjusting steps 311 to abut and fix with the boss 301 according to the water flow rate. After the pressure plate 2 is released, since the upper platform surface 3010 of the boss 301 is abutted by the first abutment surface 3111 and the rear side of the boss 301 is abutted by the second abutment surface 3110, the fastening member 30 has a rotation dead point relative to the connection point of the gun body 1. Under the pull of the torsion spring, the adjusting step 311 continues to abut and fix with the boss 301, which ultimately results in the fastening member 30 and the adjusting member 31 being in a relatively stable fastening state, and the water flow rate remains unchanged. When it is necessary to turn off the water spray gun or adjust the water flow, press the back platen 2 again and move the fastener 30 appropriately so that the boss 301 disengages from the adjustment step 311.

[0038] Furthermore, the water flow adjustment mechanism is intuitive and easy to use. Through the interaction of the adjustment piece 31 on the rear trigger 2 and the fastening piece 30 on the gun body, multi-level precise flow control is achieved. The different adjustment steps 311 allow users to select the most suitable water output according to specific needs, ensuring operational flexibility and accuracy.

[0039] Reference Figure 1 and Figure 6 The gun body 1 includes a gun body 11, a handle 10 connected to the gun body 11, and a nozzle 12 connected to the front side of the gun body 11.

[0040] The water outlet chamber 110 is located inside the gun body 11. The front end of the water outlet chamber 110 forms a water outlet hole 111 that communicates with the nozzle 12. The valve stem 22 includes a valve head 220 whose front end can move in the front-back direction within the water outlet hole 111. The valve head 220 includes a first flow port 221 opened on the side in the front-back direction, and a second flow port 222 opened on the front end face that communicates with the first flow port 221. The degree of extension and retraction of the valve head 220 in the front-back direction within the water outlet hole 111 controls the flow rate of water flowing from the water outlet chamber 110 into the water outlet hole 111.

[0041] Furthermore, water flows from the outlet chamber 110 through the first flow port 221 into the second flow port 222 of the valve head 220, and then through the second flow port 222 into the outlet hole 111. Finally, it is ejected from the nozzle 12. The back-and-forth movement of the valve head 220 within the outlet hole 111 changes the water flow rate entering the first flow port 221 from the outlet chamber 110, thereby controlling the water flow size of the nozzle 12. The back-and-forth movement of the valve head 220 is achieved by pulling the valve stem 22 using the rear trigger 2.

[0042] Reference Figure 2 , Figure 4The rear trigger 2 includes a trigger head 20 and a lever 21 connected below the trigger head 20. A hinge point 200 is provided between the trigger head 20 and the lever 21 to be hinged to the rear end of the gun body 11. The rear end of the valve stem 22 is connected inside the trigger head 20. When the lever 21 is pressed down, the trigger head 20 can pull the valve stem 22 to move backward.

[0043] Preferably, the water outlet 111 is a cylindrical hole, the valve head 220 is cylindrical, and an elastic sealing ring 223 is provided on the rear side of the valve head 220.

[0044] The handle 10 is provided with an inlet chamber 100 that communicates with the outlet chamber 110, and water flows from the inlet chamber 100 into the outlet chamber 110.

[0045] Furthermore, the water gun provided by this utility model abandons the traditional nut adjustment mechanism, instead utilizing the cooperation between the practical fastener 30 and the adjusting step 311 to achieve rapid and precise water flow adjustment. This reduces the risk of component wear, thereby increasing the overall service life of the product and reducing maintenance costs. The water flow level can be selected with simple operation, eliminating the need for cumbersome twisting motions, greatly improving ease of use and efficiency. At the same time, this design ensures good sealing performance, guaranteeing a stable water output at different settings, adapting to the needs of various working environments, and thus providing users with a more intelligent, efficient, and safe user experience.
