[0015] Compared with the prior art, the water gun provided by the embodiment of the present invention has the following advantages:

[0016] 1. In the water gun provided by the embodiment of the present invention, a self-locking area is provided on the trigger, and a self-locking structure is provided in the self-locking area. The first end of the labor-saving hook assembly is located in the self-locking area. When the trigger is pulled, the first end of the labor-saving hook assembly can move in the self-locking area. When the trigger is released, the first end of the labor-saving hook assembly is locked with the self-locking structure to achieve self-locking of the trigger. When the trigger is pulled and released again, the first end of the labor-saving hook assembly is unlocked from the self-locking structure. This solves the problem that traditional water guns are very laborious to use and may even hurt fingers, and that users may easily get hand fatigue due to pressing the trigger for a long time, resulting in poor user experience. Through the cooperation between the labor-saving hook assembly and the trigger, the water gun has a self-locking function, thereby avoiding hand fatigue caused by users pressing the trigger for a long time. The user does not need to pull the trigger hard, but only needs to hold the water gun to spray water, thereby achieving the purpose of saving effort.

[0017] 2. In the water gun provided by the embodiment of the present invention, the water gun also includes a gear assembly, which can be switched between the first state and the second state under the action of external force. When the gear assembly switches to the first state, there is an active gap between the second end of the labor-saving hook assembly and the gear assembly, and the first end of the labor-saving hook assembly moves in the self-locking area; the trigger is also provided with an active area, and when the gear assembly switches to the second state, the second end of the labor-saving hook assembly abuts the gear assembly and makes the first end of the labor-saving hook assembly located in the active area. When the trigger is pulled and released, the first end of the labor-saving hook assembly can move freely in the active area. It allows the user to freely switch between the labor-saving state and the normal state, so that the user can choose the normal state to spray water when operating for a short time, which greatly improves the convenience and practicality of the water gun and enhances the user experience.

[0018] 3. In the water gun provided in the embodiment of the present invention, a limited position area is also provided on the trigger, and the shift assembly can be switched between the first state, the second state and the third state under the action of external force. When the shift assembly switches to the third state, the second end of the labor-saving hook assembly abuts against the shift assembly and makes the first end of the labor-saving hook assembly located in the limited position. The first end of the labor-saving hook assembly abuts against the trigger so that the trigger is fixed relative to the shell and the trigger cannot be pulled, which provides a layer of insurance for the water gun, can prevent the user from accidentally triggering the water gun and causing water spraying and causing injury, and improves the safety of the water gun.

[0019] 4. In the water gun provided by the embodiment of the present invention, the shift assembly includes a sliding member, a slider and a slide rail, the slide rail is fixed in the housing, the slider is slidably connected to the slide rail, the sliding member is clamped on the slider and exposed to the housing, and the user can move the slider by operating the sliding member. A movable groove is provided on the slide rail, and the second end of the labor-saving hook assembly is located in the movable groove. The sliding member can drive the slider to approach or move away from the second end of the labor-saving hook assembly under the action of external force, and then switch between the first state, the second state and the third state; in the first state, there is an active gap between the second end of the labor-saving hook assembly and the slider, and the second end of the labor-saving hook assembly can move in the active groove. In the second state and the third state, the second end of the labor-saving hook assembly abuts the slider. The first state, the second state and the third state are quickly switched by the cooperation of a simple sliding member, a slider and a slide rail, which is easy to understand and easy to operate, can avoid user misoperation, and is also convenient for assembly and disassembly of the water gun.

[0020] 5. In the water gun provided by the embodiment of the present invention, the labor-saving hook assembly includes a supporting column, a rotating shaft, a movable hook and a tension spring. The first end of the labor-saving hook assembly is a movable hook, and the second end of the labor-saving hook assembly is a supporting column. The two ends of the rotating shaft are movably arranged on the inner wall of the shell so that the rotating shaft can rotate around the central axis. The supporting column and the movable hook are arranged on the side of the rotating shaft. One end of the tension spring is connected to the movable hook, and the other end of the tension spring is connected to the inner wall of the shell. Under the action of the supporting column, the rotating shaft, the movable hook and the tension spring, the trigger and the gear assembly that are not in the same plane are matched, thereby completing the change of the water spraying state of the water gun in the first state, the second state and the third state. In addition, the labor-saving hook assembly has a simple structure, is easy to mass produce and assemble, and is convenient for later maintenance.

[0021] 6. In the water gun provided by the embodiment of the present invention, a groove is provided on the trigger, and the groove is divided into a limit area, a movable area and a self-locking area from top to bottom. Since the abutting column and the movable hook are arranged on the side of the rotating shaft, the shift assembly gradually approaches the abutting column in the first state, the second state and the third state, and the position of the movable hook changes from bottom to top. Therefore, by limiting the order of the limit area, the movable area and the self-locking area, it can be matched with the state change of the shift assembly, so as to adapt to the change of the water spraying state of the water gun in the three states.

[0022] In addition, the smooth corner transition between the groove edge of the limiting area and the groove edge of the active area can achieve a natural switch between the second state and the third state, avoiding jamming when pulling the trigger.

[0023] In addition, the edge of the groove in the limiting zone is closer to the movable hook than the edge of the groove in the movable zone. In the third state, the movable hook abuts against the edge of the groove in the limiting zone. The switching between the second state and the third state is achieved by limiting the distance between the edge of the groove in the limiting zone and the edge of the groove in the movable zone and the movable hook. No other components need to be coordinated, making the overall structure of the water gun simpler.

[0024] 7. In the water gun provided by the embodiment of the present invention, the smooth transition between the groove edge of the self-locking area and the groove edge of the active area can make the switching between the first state and the second state smoother.

[0025] 8. The water gun provided by the embodiment of the present invention has a self-locking structure including an arc-shaped bayonet and a step. The step is arranged corresponding to the opening of the arc-shaped bayonet. In the first state, there is a movable gap between the supporting column and the shift assembly. When the trigger is pulled, the movable hook hooks the arc-shaped bayonet under the action of the tension spring and the step. When the trigger is released, the movable hook is locked with the arc-shaped bayonet to realize the self-locking of the trigger. When the trigger is pulled and released again, the movable hook is separated from the arc-shaped bayonet under the action of the tension spring and the step to release the lock. The locking and releasing of the trigger is realized by forming a self-locking structure with the arc-shaped bayonet and the step. The structure is simple, the manufacturing cost is reduced, the failure rate is reduced, and the reliability of the water gun as a whole is improved.

[0026] 9. In the water gun provided in the embodiment of the present invention, the step is located on the center line of the arc-shaped bayonet. Through such a design, it can be ensured that when the trigger is pulled and released again, the trigger is successfully released from self-locking.

[0027] 10. In the water gun provided by the embodiment of the present invention, the water inlet pipe and the water outlet pipe are both installed on the shell, one end of the water outlet pipe is connected to one side of the valve body, the upper end of the water inlet pipe is connected to the lower end of the valve body, the lower side of one end of the trigger abuts against one end of the pressure spring, and the other end of the pressure spring is connected to the upper end of the valve body. When the trigger is pulled, the pressure spring is pressed and the valve body is driven to connect the water inlet pipe with the water outlet pipe. When the trigger is released, the pressure spring restores its deformation and drives the valve body to close the water inlet pipe and the water outlet pipe. The embodiment of the present invention facilitates opening the valve body by pressing the trigger to connect the water inlet pipe and the water outlet pipe through the cooperation of the trigger, the pressure spring and the valve body, thereby reducing the burden on the user's hands. At the same time, when the user releases the trigger, the pressure spring restores its deformation to return the trigger to a normal state. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Please combine Figure 1-Figure 3 As shown, an embodiment of the present invention provides a water gun 1, which includes a housing 11, a gear assembly 12, a labor-saving hook assembly 13 and a trigger 14. The labor-saving hook assembly 13 is arranged in the housing 11 and can rotate relative to the housing 11, the gear assembly 12 is partially exposed to the housing 11 and can move relative to the housing 11, one end of the trigger 14 is rotatably connected to the housing 11, and the other end of the trigger 14 is exposed to the housing 11 and can move relative to the housing 11. The gear assembly 12 can be switched between the first state, the second state and the third state under the action of external force,

[0047] Please continue reading Figure 2 and Figure 3As shown, further, the water gun 1 also includes a water inlet pipe 15, a water outlet pipe 16, a valve body 17 and a pressure spring 18, and the water inlet pipe 15 and the water outlet pipe 16 are both installed in the housing 11. One end of the water outlet pipe 16 is connected to one side of the valve body 17, the upper end of the water inlet pipe 15 is connected to the lower end of the valve body 17, the lower side of one end of the trigger 14 abuts against one end of the pressure spring 18, and the other end of the pressure spring 18 is connected to the upper end of the valve body 17. When the trigger 14 is pulled, the pressure spring 18 is pressed and the valve body 17 is driven to connect the water inlet pipe 15 with the water outlet pipe 16, and when the trigger 14 is released, the pressure spring 18 recovers its deformation and drives the valve body 17 to close the water inlet pipe 15 and the water outlet pipe 16.

[0048] In the embodiment of the present invention, through the cooperation of the trigger 14, the pressure spring 18 and the valve body 17, it is convenient to open the valve body 17 by pressing the trigger 14 to connect the water inlet pipe 15 and the water outlet pipe 16, thereby reducing the burden on the user's hands. At the same time, when the user releases the trigger 14, the pressure spring 18 recovers its deformation so that the trigger 14 returns to a normal state to close the water inlet pipe 15 and the water outlet pipe 16.

[0049] It should be noted that the valve body 17 controlling the connection or closing of the water inlet pipe 15 and the water outlet pipe 16 is a prior art and will not be described in detail in the embodiment of the present invention.

[0050] Please combine Figure 3 and Figure 4 As shown, specifically, the shift assembly 12 includes a sliding member 121, a slider 122 and a slide rail 123. The slide rail 123 is fixed in the housing 11, the slider 122 is slidably connected to the slide rail 123, the sliding member 121 is clamped on the slider 122 and exposed to the housing 11, and the user can move the slider 122 by operating the sliding member 121. A movable groove 1231 is provided on the slide rail 123, and the labor-saving hook assembly 13 includes a first end and a second end, wherein the second end of the labor-saving hook assembly 13 is located in the movable groove 1231, and the sliding member 121 can drive the slider 122 to approach or move away from the second end of the labor-saving hook assembly 13 under the action of external force, and then switch between the first state, the second state and the third state.

[0051] It can be understood that in the first state, there is a movable gap between the second end of the labor-saving hook component 13 and the slider 122, and the second end of the labor-saving hook component 13 can move in the movable groove 1231. In the second state and the third state, the second end of the labor-saving hook component 13 abuts the slider 122.

[0052] More specifically, the acting force between the effort-saving hook assembly 13 and the slider 122 in the third state is greater than the acting force between the effort-saving hook assembly 13 and the slider 122 in the second state.

[0053] In the embodiment of the present invention, the first state, the second state and the third state are quickly switched by simply cooperating with the sliding member 121, the slider 122 and the slide rail 123. This is easy to understand and operate, can avoid user misoperation, and is also convenient for assembly and disassembly of the water gun 1.

[0054] Please combine Figure 2 , Figure 5 and Figure 6 As shown, specifically, the labor-saving hook assembly 13 includes a supporting column 131, a rotating shaft 132, a movable hook 133 and a tension spring 134. Among them, the first end of the labor-saving hook assembly 13 is the movable hook 133, the second end of the labor-saving hook assembly 13 is the supporting column 131, the two ends of the rotating shaft 132 are movably arranged on the inner wall of the housing 11 so that the rotating shaft 132 can rotate around the central axis, the supporting column 131 and the movable hook 133 are arranged on the side of the rotating shaft 132, one end of the tension spring 134 is connected to the movable hook 133, and the other end of the tension spring 134 is connected to the inner wall of the housing 11.

[0055] Optionally, the angle between the abutting column 131 and the movable hook 133 is 30° to 90°. For example, the angle is 30°, 45°, 90°, etc. By limiting the angle between the abutting column 131 and the movable hook 133, the limited space inside the shell 11 of the water gun 1 can be utilized to the maximum extent, thereby improving the space occupancy rate of the shell 11.

[0056] In the embodiment of the present invention, under the action of the supporting column 131, the rotating shaft 132, the movable hook 133 and the tension spring 134, the trigger 14 and the shift assembly 12 which are not in the same plane are matched, thereby completing the change of the water spraying state of the water gun in the first state, the second state and the third state. In addition, the labor-saving hook assembly 13 has a simple structure, is easy to mass produce and assemble, and is convenient for later maintenance.

[0057] Please combine Figure 7 and Figure 8 As shown, specifically, a groove 141 is provided on the trigger 14, and the groove 141 is divided into a limit area 142, a movable area 143 and a self-locking area 144 from top to bottom (the direction from top to bottom refers to the direction from the groove 141 close to the gear assembly 12 to the groove 141 away from the gear assembly 12), wherein the self-locking area is provided with a self-locking structure 19.

[0058] It can be understood that, since the abutting column 131 and the movable hook 133 are arranged on the side of the rotating shaft 132, the gear assembly 12 gradually approaches the abutting column 131 in the first state, the second state and the third state, and the position of the movable hook 133 changes from bottom to top (the direction from bottom to top refers to the direction from the groove 141 away from the gear assembly 12 to the groove 141 close to the gear assembly 12). Therefore, by limiting the order of the limiting area 142, the movable area 143 and the self-locking area 144, it can be matched with the state change of the gear assembly 12, so as to adapt to the change of the water spraying state of the water gun 1 in the three states.

[0059] More specifically, in the third state, the movable hook 133 abuts against the edge of the groove 141 of the limiting area 142 .

[0060] Preferably, the edges of the groove 141 of the limiting area 142 and the groove 141 of the active area 143 are smoothly transitioned at the corners. By setting in this way, a natural switch between the second state and the third state can be achieved, and a jamming when the trigger 14 is pulled can be avoided.

[0061] In the embodiment of the present invention, the switching between the second state and the third state is achieved by limiting the distance between the edge of the groove 141 of the limiting area 142 and the edge of the groove 141 of the movable area 143 and the movable hook 133, without the need for cooperation of other components, making the overall structure of the water gun 1 simpler.

[0062] Preferably, the edge of the groove 141 of the limiting area 142 is closer to the movable hook 133 than the edge of the groove 141 of the movable area 143 .

[0063] Preferably, there is a smooth transition between the edge of the groove 141 of the self-locking area 144 and the edge of the groove 141 of the active area 143. By such an arrangement, the switching between the first state and the second state can be made smoother.

[0064] Specifically, when the shift assembly 12 switches to the first state, there is an active gap between the second end of the labor-saving hook assembly 13 and the shift assembly 12, and the first end of the labor-saving hook assembly 13 is located in the self-locking area 144. When the trigger 14 is pulled, the first end of the labor-saving hook assembly 13 can move in the self-locking area 144 due to the existence of the active gap. When the trigger 14 is released, the first end of the labor-saving hook assembly 13 is locked with the self-locking structure 19 to achieve the self-locking of the trigger 14. When the trigger 14 is pulled and released again, the first end of the labor-saving hook assembly 13 is unlocked from the self-locking structure 19. The problem that the traditional water gun is very laborious to use and even easy to hurt the fingers, and the user's hand fatigue is easy to cause by pressing the trigger for a long time, and the user experience is poor is solved. Through the cooperation between the shift assembly 12, the labor-saving hook assembly 13 and the trigger 14, the water gun 1 has a self-locking function, thereby avoiding the user's hand fatigue caused by pressing the trigger for a long time. The user does not need to pull the trigger 14 hard, but only needs to hold the water gun 1 to spray water, thereby achieving the purpose of labor saving.

[0065] Specifically, when the shift assembly 12 switches to the second state, the second end of the labor-saving hook assembly 13 abuts against the shift assembly 12 and makes the first end of the labor-saving hook assembly 13 located in the activity area 143. When the trigger 14 is pulled or released, the first end of the labor-saving hook assembly 13 can move freely in the activity area 143. The user can freely switch between the labor-saving state and the normal state, and can realize water spraying by pressing the trigger 14 and stopping when releasing the trigger 14, so that the user can select the normal state to spray water when operating for a short time, which greatly improves the convenience and practicality of the water gun 1 and enhances the user experience.

[0066] Specifically, when the shift assembly 12 switches to the third state, the second end of the effort-saving hook assembly 13 abuts against the shift assembly 12 and makes the first end of the effort-saving hook assembly 13 located in the limit area 142, and the first end of the effort-saving hook assembly 13 abuts against the trigger 14 to fix the trigger 14 relative to the housing 11, thereby making the trigger 14 unable to be pulled, providing a layer of insurance for the water gun 1, which can prevent the user from accidentally triggering the water gun 1 and causing water spraying and causing injury, thereby improving the safety of the water gun 1.

[0067] It can be understood that the first state is a labor-saving state, in which the user can use the water gun 1 with great labor-saving. The second state is a normal state, in which the user uses the water gun 1, and sprays water when the trigger 14 is pulled, and stops spraying water when the trigger 14 is released. The third state is a locked state, in which the trigger 14 cannot be pulled, and the water gun 1 cannot spray water.

[0068] Please continue to combine Figure 7 and Figure 8 As shown, specifically, the self-locking structure 19 includes an arc-shaped bayonet 1441 and a step 1442 , and the step 1442 is arranged corresponding to the opening of the arc-shaped bayonet 1441 .

[0069] In the first state, there is a movable gap between the supporting column 131 and the shift assembly 12. When the trigger 14 is pulled, the movable hook 133 hooks the arc-shaped bayonet 1441 under the action of the tension spring 134 and the step 1442. When the trigger 14 is released, the movable hook 133 is locked with the arc-shaped bayonet 1441 to achieve self-locking of the trigger 14. When the trigger 14 is pulled and released again, the movable hook 133 is disengaged from the arc-shaped bayonet 1441 under the action of the tension spring 134 and the step 1442 to release the lock. The locking and release of the trigger 14 are achieved by forming a self-locking structure 19 through the arc-shaped bayonet 1441 and the step 1442. The structure is simple, the manufacturing cost is reduced, the failure rate is reduced, and the overall reliability of the water gun 1 is improved.

[0070] Specifically, the arc-shaped bayonet 1441 and the step 1442 are integrally formed on the trigger 14 , which can make the water gun 1 have higher structural strength and durability.

[0071] Preferably, the arc-shaped bayonet 1441 is crescent-shaped, which can ensure that the locking and releasing of the trigger 14 are smoother and reduce jamming.

[0072] Preferably, the step 1442 is located on the center line of the arc-shaped bayonet 1441. Through such a design, it can be ensured that when the trigger 14 is pulled and released again, the trigger 14 is successfully released from self-locking.

[0073] More specifically, the step 1442 is a sharp triangle protrusion on the edge of the groove 141 of the self-locking area 144. Through the setting of the sharp triangle, it is possible to avoid the self-locking failure of the trigger 14 due to excessive pressing when performing the self-locking operation, thereby improving the self-locking success rate of the trigger 14.

[0074] Furthermore, an auxiliary slope 1443 may be provided on the self-locking area 144, and the auxiliary slope is provided near the arc-shaped bayonet 1441. By providing the auxiliary slope 1443, the height of the movable hook 133 can be raised and the movable hook 133 can be guided into the arc-shaped bayonet 1441 for locking, thereby improving the accuracy of the self-locking of the trigger 14.

[0075] For ease of understanding, the operating process of the water gun 1 is described in the embodiment of the present invention, but this should not be construed as a limitation.

[0076] When using the water gun 1, if the user needs to operate for a long time, the sliding member 121 can be moved to the first state, i.e., the labor-saving state. At this time, there is an active gap between the abutting column 131 and the sliding block 122, and the abutting column 131 can move in the movable groove 1231, and the movable hook 133 is located on the self-locking area 144. Pull the trigger 14, and with the cooperation of the step 1442, the movable hook 133 is pulled into the arc-shaped bayonet 1441 by the tension spring 134 and hooked to achieve the self-locking of the trigger 14. At this time, there is no need for the human hand to keep holding the trigger 14, and the water gun 1 can achieve continuous water spraying. If it is necessary to stop spraying water, it is only necessary to pull the trigger 14 again. With the cooperation of the step 1442, the movable hook 133 will be pulled out of the arc-shaped bayonet 1441 by the tension spring 134. At this time, the human hand releases the trigger 14, and the trigger 14 is pushed to the non-working state by the pressure spring 18, and the water spraying stops.

[0077] If the user only needs to operate for a short time, the sliding member 121 can be moved to the second state, i.e., the normal state, at which the abutting column 131 abuts against the sliding block 122, and the movable hook 133 is located on the movable area 143 and does not hook the trigger 14. When the trigger 14 is pulled, the water gun 1 sprays water, and when the trigger 14 is released, the water gun 1 stops spraying water.

[0078] If the user does not need to use the water gun 1, the sliding member 121 can be moved to the third state, i.e., the locked state, in which the abutting column 131 abuts against the sliding block 122, and the movable hook 133 is located on the limiting area 142 and abuts against the edge of the groove 141 of the groove 141. In this state, the trigger 14 cannot be pulled, and the water gun 1 cannot spray water.

[0079] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
