Description

Technical Field

[0001] The invention relates to the technical field of water spray guns, and in particular to a water spray gun which is convenient for adjusting water flow. Background Art

[0002] In daily life, water spray guns are widely used as important tools for cleaning, gardening irrigation, and entertainment. Traditionally designed water spray guns usually use nuts to control the size and switch of the water flow. Users need to manually rotate the nut to adjust to the appropriate water flow rate. This process is not only time-consuming and labor-intensive, but also prone to nut wear or loss of precision in the case of frequent adjustments, affecting user experience and product life. In addition, in some special application scenarios, such as fast-response cleaning operations, the traditional nut adjustment method is not convenient enough. For tasks that require rapid changes in water flow intensity, each adjustment means additional time costs and may miss the best working time. Summary of the invention

[0003] In view of this, an object of the present invention 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 the present invention to solve the technical problem is:

[0005] A water spray gun convenient for adjusting water flow comprises a gun body and a back pressure trigger arranged at the rear side of the gun body, a water outlet cavity is formed in the gun body, and a valve stem capable of adjusting the flow rate of the water outlet cavity is arranged in the back pressure trigger;

[0006] The rear pressure trigger is hinged on the rear side of the gun body. Pressing and rotating the rear pressure trigger can pull the valve stem to control the flow rate of water in the water outlet chamber. The rear pressure trigger is provided with an adjusting piece, and the rear side of the gun body is provided with a buckling piece for abutting against the adjusting piece to lock the rear pressure trigger.

[0007] A plurality of steps are formed on the front side of the adjusting member from top to bottom, and a boss is formed on the rear side of the buckling member. When the rear compression trigger is rotated to different positions, the boss can be abutted and fixed in the corresponding steps to lock the rear compression trigger.

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

[0009] The closed groove comprises an upper abutting plane located at the upper side of the groove and a lower abutting inclined plane located at the lower side of the groove, and the adjusting step is arranged below the lower abutting inclined plane.

[0010] The boss comprises an upper surface, and the adjustment step comprises a first abutting surface for abutting against the upper surface, and a second abutting surface for abutting against the rear side surface 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 arranged in the gun body, and a water outlet hole connected with the nozzle is formed at the front end of the water outlet chamber. The valve stem includes a valve head whose front end can move in the water outlet hole along the front-to-back direction; the valve head includes a first flow port opened in the side along the front-to-back direction, and a second flow port opened on the front end surface and connected with the first flow port. The extension degree of the valve head in the front-to-back direction in the water outlet hole is used to control the flow rate of water flowing from the water outlet chamber into the water outlet hole.

[0013] The rear pressure trigger includes a trigger head and a pressure handle connected below the trigger head, and a hinge point hinged to the rear end of the gun body is arranged between the trigger head and the pressure handle; the rear end of the valve stem is connected to the trigger head, and when the pressure handle is pressed down, the trigger head can pull the valve stem to move backward.

[0014] The adjusting member is arranged at the front side of the upper end of the trigger head, and a torsion spring is arranged at the hinge point. When the trigger is pressed back without external force, the torsion spring pulls the trigger head to rotate forward so that the adjusting member is in contact with the buckling member.

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

[0016] The buckle piece is in the shape of a semicircular ring and is hinged on the gun body. A raised toggle ring is formed on the outer surface of the buckle piece.

[0017] A water inlet cavity communicated with the water outlet cavity is arranged in the handle.

[0018] The beneficial effects of the present invention are:

[0019] 1. It provides an intuitive and easy-to-use adjustment mechanism, which realizes multi-level precise flow control through the adjustment piece set on the rear pressure trigger and the buckle piece on the gun body. The different levels of adjustment step design allow users to choose the most suitable water output according to specific needs, ensuring the flexibility and accuracy of operation.

[0020] 2. The water spray gun provided by the present invention abandons the traditional nut adjustment mechanism and instead uses the cooperation between the practical buckle and the adjustment step to achieve rapid and precise adjustment of the water flow. The water flow size can be selected through simple operations without the need for cumbersome twisting movements as in the past, which greatly improves the convenience and efficiency of use. At the same time, this design can also ensure good sealing performance, ensure stable water output under different gears, and adapt to the needs of various working environments, thereby providing users with a more intelligent, efficient and safe use experience.

[0027] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention are further described below in conjunction with the accompanying drawings and through specific implementation methods. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, not all.

[0028] Reference Figure 1 , Figure 2 The present invention proposes a water spray gun that is convenient for adjusting water flow, comprising a gun body 1, a rear pressure trigger 2 arranged at the rear side of the gun body 1, a water outlet cavity 110 is formed in the gun body 1, and a valve stem 22 capable of adjusting the flow of the water outlet cavity 110 is arranged in the rear pressure trigger 2;

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

[0030] Reference Figure 2 , Figure 3 A plurality of steps are formed on the front side of the adjusting member 31 from top to bottom, and a boss 301 is formed on the rear side of the buckling member 30. When the rear compression trigger 2 rotates to different positions, the boss 301 can be abutted and fixed in the corresponding steps to lock the rear compression trigger 2.

[0031] Reference Figure 3 , Figure 5 The steps include a closed groove 310 and a plurality of adjustment steps 311. When the boss 301 cooperates with the closed groove 310, the valve stem 22 can block the water outlet cavity 110, and the water spray gun is in a closed state; when the boss 301 abuts against different adjustment steps 311, the valve stem 22 opens the water outlet cavity 110 to different degrees, and the water outlet flow rate of the water spray gun is different.

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

[0033] Specifically, when the boss 301 cooperates with the closed groove 310, the upper abutting plane 3100 can abut against the upper table surface 3010 to prevent the boss 301 from disengaging from the closed groove 310. When the adjusting member 31 rotates backward, the lower abutting slope 3101 can make the boss 301 easily disengage from the closed groove 310.

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

[0035] The adjusting member 31 is arranged at the front side of the upper end of the trigger head 20 , and a torsion spring is arranged at the hinge point 200 . When the trigger 2 is pressed back without external force, the torsion spring pulls the trigger head 20 to rotate forward so that the adjusting member 31 abuts against the buckling member 30 .

[0036] The buckle member 30 is in the shape of a semicircular ring and is hinged to the gun body 1 . A raised toggle ring 300 is formed on the outer surface of the buckle member 30 .

[0037] Furthermore, when it is necessary to open the water spray gun, the rear pressure plate 2 is pressed down, the valve stem 2 controls the flow of the water outlet chamber 110, the adjusting member 31 rotates backward, and the closing groove 310 gradually disengages from the lower abutting inclined surface 3101 of the boss 301. At this time, the toggle ring 300 is turned, and different adjustment steps 311 are selected according to the water flow rate to abut and fix with the boss 301, and the rear pressure plate 2 is released. Since the upper surface 3010 of the boss 301 is abutted by the first abutting surface 3111 and the rear side surface of the boss 301 is abutted by the second abutting surface 3110, there is a rotational dead point at the connection point of the fastening member 30 relative to the gun body 1, and under the pull of the torsion spring, the adjustment step 311 continues to abut and be fixed on the boss 301, which eventually causes the fastening member 30 and the adjusting member 31 to be in a relatively stable fastening state, and the water flow remains unchanged. When it is necessary to close the water gun or adjust the water flow, the rear pressing plate machine 2 needs to be pressed again, and the buckle member 30 needs to be properly moved so that the boss 301 is separated from the adjustment step 311 .

[0038] Furthermore, the water flow adjustment mechanism is intuitive and easy to use, and the adjustment member 31 provided on the rear pressure trigger 2 cooperates with the buckle member 30 on the gun body to achieve multi-level precise flow control. The design of different levels of adjustment steps 311 allows the user to select the most suitable water output according to specific needs, ensuring the flexibility and accuracy of operation.

[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 arranged in the gun body 11, and a water outlet hole 111 connected to the nozzle 12 is formed at the front end of the water outlet chamber 110. The valve stem 22 includes a valve head 220 whose front end can move in the water outlet hole 111 along the front-to-back direction; the valve head 220 includes a first flow port 221 opened on the side along the front-to-back direction, and a second flow port 222 opened on the front end surface and connected to the first flow port 221. The degree of expansion and contraction of the valve head 220 in the water outlet hole 111 along the front-to-back direction is used to control the flow rate of water flowing from the water outlet chamber 110 into the water outlet hole 111.

[0041] Furthermore, water flows from the water outlet cavity 110 through the first flow port 221 into the second flow port 222 of the valve head 220, and then enters the water outlet hole 111 through the second flow port 222. Finally, it is sprayed out from the nozzle 12. The forward and backward movement of the valve head 220 in the water outlet hole 111 can change the water flow rate of the water outlet cavity 110 entering the first flow port 221, thereby controlling the water flow size of the nozzle 12. The forward and backward movement of the valve head 220 is achieved by pulling the valve stem 22 by pressing the trigger 2 backward.

[0042] Reference Figure 2 , Figure 4The rear pressure trigger 2 includes a trigger head 20 and a pressure handle 21 connected to the bottom of the trigger head 20, and a hinge point 200 is provided between the trigger head 20 and the pressure handle 21, which is hinged to the rear end of the gun body 11; the rear end of the valve stem 22 is connected to the trigger head 20, and when the pressure handle 21 is pressed down, the trigger head 20 can pull the valve stem 22 to move backward.

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

[0044] A water inlet chamber 100 communicating with the water outlet chamber 110 is disposed in the handle 10 , and water flows into the water outlet chamber 110 from the water inlet chamber 100 .

[0045] Furthermore, the water spray gun provided by the present invention abandons the traditional nut adjustment mechanism and instead uses the cooperation between the practical buckle 30 and the adjustment step 311 to achieve rapid and precise adjustment of the water flow. The risk of component wear is reduced, thereby increasing the overall service life of the product and reducing maintenance costs. The water flow size can be selected through simple operations without the need for cumbersome twisting movements as in the past, which greatly improves the convenience and efficiency of use. At the same time, this design can also ensure good sealing performance, ensure stable water output under different gears, and adapt to the needs of various working environments, thereby providing users with a more intelligent, efficient and safe use experience.
