Description

Technical Field

[0001] This utility model relates to the field of water gun technology, and in particular to a water gun. Background Technology

[0002] With the improvement of living standards, household pressure washers have become popular as a very effective cleaning tool. The water gun is the main component of a pressure washer. It is a machine that uses a power unit to drive a high-pressure plunger pump to generate high-pressure water to rinse the surface of objects. It can peel off and wash away dirt, thus achieving the purpose of cleaning the surface of objects.

[0003] However, most high-pressure washer water guns on the market currently use a movable trigger as a switch. Since the water pressure of high-pressure washer ranges from 50 kg to over 200 kg, users need to overcome the extremely high pressure of the water flow when pulling the trigger, which is very strenuous and can even easily injure their fingers. Furthermore, prolonged pressing of the trigger can cause hand fatigue, resulting in a poor user experience. Utility Model Content

[0004] To address the problems of traditional water guns being very laborious to use, potentially causing finger injuries, and resulting in hand fatigue and a poor user experience due to prolonged trigger pressing, this utility model provides a water gun.

[0005] To solve the above-mentioned technical problems, one technical solution adopted by this utility model is to provide a water gun, which includes a housing, a force-saving hook assembly, and a trigger. The force-saving hook assembly is disposed inside the housing and can rotate relative to the housing. The trigger part is exposed outside the housing and can move relative to the housing. The trigger has a self-locking area, and the self-locking area is provided with a self-locking structure. The first end of the force-saving hook assembly is located in the self-locking area. When the trigger is pulled, the first end of the force-saving hook assembly moves within the self-locking area. When the trigger is released, the first end of the force-saving hook assembly locks with the self-locking structure to achieve trigger self-locking. When the trigger is pulled and released again, the first end of the force-saving hook assembly is unlocked from the self-locking structure.

[0006] In one embodiment, the water gun further includes a stop assembly that can switch between a first state and a second state under external force. When the stop assembly switches to the first state, there is a movable gap between the second end of the effort-saving hook assembly and the stop assembly, and the first end of the effort-saving hook assembly moves within the self-locking zone. The trigger also has a movable zone. When the stop assembly switches to the second state, the second end of the effort-saving hook assembly abuts against the stop assembly, causing the first end of the effort-saving hook assembly to be located in the movable zone. When the trigger is pulled and released, the first end of the effort-saving hook assembly can move freely within the movable zone.

[0007] In one embodiment, the trigger is further provided with a limiting area. The stop assembly can be switched between a first state, a second state, and a third state under the action of an external force. When the stop assembly switches to the third state, the second end of the force-saving hook assembly abuts against the stop assembly and the first end of the force-saving hook assembly is located in the limiting area. The first end of the force-saving hook assembly abuts against the trigger so that the trigger is fixed relative to the housing.

[0008] In one embodiment, the stop assembly includes a slider, a slider, and a slide rail. The slide rail is fixed inside the housing, the slider is slidably connected to the slide rail, and the slider is engaged with the slider and exposed outside the housing. A movable groove is provided on the slide rail, and the second end of the force-saving hook assembly is located in the movable groove. When the slider is subjected to external force, it can drive the slider to move closer to or further away from the second end of the force-saving hook assembly, thereby switching between the first state, the second state, and the third state. In the first state, there is a movable gap between the second end of the force-saving hook assembly and the slider, and the second end of the force-saving hook assembly can move in the movable groove. In the second and third states, the second end of the force-saving hook assembly abuts against the slider.

[0009] In one embodiment, the effort-saving hook assembly includes a supporting post, a rotating shaft, a movable hook, and a tension spring. The first end of the effort-saving hook assembly is the movable hook, and the second end of the effort-saving hook assembly is the supporting post. The two ends of the rotating shaft are movably disposed on the inner wall of the housing so that the rotating shaft can rotate around a central axis. The supporting post and the movable hook are disposed 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 housing.

[0010] In one embodiment, the trigger has a groove, which is divided from top to bottom into a limiting area, a movable area, and a self-locking area; the groove edge of the limiting area and the groove edge of the movable area have a smooth corner transition, and the groove edge of the limiting area is closer to the movable hook than the groove edge of the movable area; in the third state, the movable hook abuts against the groove edge of the limiting area.

[0011] In one embodiment, the groove edge of the self-locking region and the groove edge of the active region have a smooth transition.

[0012] In one embodiment, the self-locking structure includes an arc-shaped latch and a step, with the step corresponding to the opening of the arc-shaped latch. In the first state, when the trigger is pulled, the movable hook engages with the arc-shaped latch under the action of the tension spring and the step. When the trigger is released, the movable hook locks with the arc-shaped latch to achieve trigger self-locking. When the trigger is pulled and released again, the movable hook disengages from the arc-shaped latch under the action of the tension spring and the step to release the lock.

[0013] In one embodiment, the step is located on the center line of the arc-shaped bayonet.

[0014] In one embodiment, the water gun further includes an inlet pipe, an outlet pipe, a valve body, and a pressure spring. The inlet pipe and the outlet pipe are both installed in the housing. One end of the outlet pipe is connected to one side of the valve body, and the upper end of the 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 inlet pipe and the outlet pipe. When the trigger is released, the pressure spring returns to its original deformation and drives the valve body to close the inlet pipe and the outlet pipe.

[0015] Compared with the prior art, the water gun provided in this embodiment of the utility model has the following advantages:

[0016] 1. In the water gun provided by this utility model embodiment, 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 effort-saving hook assembly is located in the self-locking area. When the trigger is pulled, the first end of the effort-saving hook assembly can move within the self-locking area. When the trigger is released, the first end of the effort-saving hook assembly locks with the self-locking structure to achieve trigger self-locking. When the trigger is pulled and released again, the first end of the effort-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 injure fingers. Furthermore, prolonged use of the trigger can cause hand fatigue and a poor user experience. Through the cooperation between the effort-saving hook assembly and the trigger, the water gun has a self-locking function, thereby avoiding hand fatigue caused by prolonged use of the trigger. Users do not need to pull the trigger forcefully; they only need to hold the water gun to spray water, thus achieving the purpose of saving effort.

[0017] 2. The water gun provided in this embodiment of the utility model further includes a stop assembly. The stop assembly can switch between a first state and a second state under external force. When the stop assembly switches to the first state, there is a movable gap between the second end of the effort-saving hook assembly and the stop assembly, and the first end of the effort-saving hook assembly moves within the self-locking zone. The trigger also has a movable zone. When the stop assembly switches to the second state, the second end of the effort-saving hook assembly abuts against the stop assembly, causing the first end of the effort-saving hook assembly to be located in the movable zone. Pulling and releasing the trigger allows the first end of the effort-saving hook assembly to move freely within the movable zone. This allows the user to freely switch between the effort-saving state and the normal state, enabling the user to choose the normal state for spraying water during short-term operation, greatly improving the convenience and practicality of the water gun and enhancing the user experience.

[0018] 3. In the water gun provided in this embodiment of the utility model, a limiting area is also provided on the trigger. The stop assembly can switch between the first state, the second state and the third state under the action of external force. When the stop assembly switches to the third state, the second end of the force-saving hook assembly abuts against the stop assembly and makes the first end of the force-saving hook assembly located in the limiting area. The first end of the force-saving hook assembly abuts against the trigger so that the trigger is fixed relative to the housing and thus the trigger cannot be pulled. This adds a layer of safety to the water gun and can prevent the user from accidentally triggering the water gun and causing water spray and injury, thereby improving the safety of the water gun.

[0019] 4. In the water gun provided by this utility model embodiment, the stop assembly includes a slider, a slider, and a slide rail. The slide rail is fixed inside the housing, the slider is slidably connected to the slide rail, and the slider is engaged with the slider and exposed outside the housing. The user can move the slider by operating the slider. A movable groove is provided on the slide rail, and the second end of the effort-saving hook assembly is located in the movable groove. When the slider is subjected to external force, it can drive the slider to move closer to or further away from the second end of the effort-saving hook assembly, thereby switching between the first state, the second state, and the third state. In the first state, there is a movable gap between the second end of the effort-saving hook assembly and the slider, and the second end of the effort-saving hook assembly can move in the movable groove. In the second and third states, the second end of the effort-saving hook assembly abuts against the slider. The quick switching between the first, second, and third states is achieved through the simple cooperation of the slider, slider, and slide rail, which is easy to understand and operate, avoids user misoperation, and facilitates the assembly and disassembly of the water gun.

[0020] 5. In the water gun provided by this embodiment, the effort-saving hook assembly includes a supporting post, a rotating shaft, a movable hook, and a tension spring. The first end of the effort-saving hook assembly is the movable hook, and the second end is the supporting post. The two ends of the rotating shaft are movably disposed on the inner wall of the housing so that the rotating shaft can rotate around the central axis. The supporting post and the movable hook are disposed 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 housing. Under the action of the supporting post, the rotating shaft, the movable hook, and the tension spring, the trigger and the stop assembly, which are not in the same plane, are able to cooperate, thereby completing the water spray state changes of the water gun in the first, second, and third states. In addition, the effort-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 in this embodiment of the utility model, a groove is provided on the trigger, which is divided into a limiting area, a movable area, and a self-locking area from top to bottom. Since the supporting post and the movable hook are located on the side of the rotating shaft, the stop assembly gradually approaches the supporting post in the first, second, and third states, and the position of the movable hook changes from bottom to top. Therefore, by limiting the order of the limiting area, the movable area, and the self-locking area, it can be matched with the state changes of the stop assembly to adapt to the changes in the water spray 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 enables a natural switch between the second and third states, avoiding jamming when the trigger is pulled.

[0023] In addition, the edge of the groove in the limiting area is closer to the movable hook than the edge of the groove in the active area. In the third state, the movable hook abuts against the edge of the groove in the limiting area. The switching between the second and third states is achieved by limiting the distance between the edge of the groove in the limiting area and the edge of the groove in the active area and the movable hook. No other parts are required, making the overall structure of the water gun simpler.

[0024] 7. In the water gun provided by this utility model embodiment, the groove edge of the self-locking area and the groove edge of the active area have a smooth transition, which makes the switching between the first state and the second state smoother.

[0025] 8. The water gun provided in this embodiment of the utility model has a self-locking structure including an arc-shaped latch and a step. The step is set corresponding to the opening of the arc-shaped latch. In the first state, there is a movable gap between the holding post and the stop assembly. When the trigger is pulled, the movable hook hooks onto the arc-shaped latch under the action of the tension spring and the step. When the trigger is released, the movable hook locks with the arc-shaped latch to achieve trigger self-locking. When the trigger is pulled and released again, the movable hook disengages from the arc-shaped latch under the action of the tension spring and the step to release the lock. The self-locking structure formed by the arc-shaped latch and the step realizes the locking and releasing of the trigger. The structure is simple, reduces manufacturing costs, reduces the failure rate, and improves the overall reliability of the water gun.

[0026] 9. In the water gun provided in this embodiment of the utility model, the step is located on the center line of the arc-shaped bayonet. This design ensures that when the trigger is pulled and released again, the trigger is successfully released from its self-locking mechanism.

[0027] 10. In the water gun provided by this embodiment of the utility model, both the inlet pipe and the outlet pipe are installed in the housing. One end of the outlet pipe is connected to one side of the valve body, and the upper end of the 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 inlet pipe and the outlet pipe. When the trigger is released, the pressure spring returns to its original deformation and drives the valve body to close the inlet pipe and the outlet pipe. This embodiment of the utility model, through the cooperation of the trigger, the pressure spring, and the valve body, facilitates opening the valve body by pressing the trigger to connect the inlet pipe and the outlet pipe, reducing the user's hand burden. At the same time, when the user releases the trigger, the pressure spring returns to its original deformation, allowing the trigger to return to its normal state. Attached Figure Description

[0046] Please combine Figures 1-3 As shown, this embodiment of the present invention provides a water gun 1, which includes a housing 11, a stop assembly 12, a force-saving hook assembly 13, and a trigger 14. The force-saving hook assembly 13 is disposed within the housing 11 and can rotate relative to the housing 11. The stop assembly 12 is partially exposed outside 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 outside the housing 11 and can move relative to the housing 11. The stop assembly 12 can switch between a first state, a second state, and a third state under the action of external force.

[0047] Please continue reading. Figure 2 and Figure 3As shown, the water gun 1 further includes an inlet pipe 15, an outlet pipe 16, a valve body 17, and a pressure spring 18. Both the inlet pipe 15 and the outlet pipe 16 are installed within the housing 11. One end of the outlet pipe 16 is connected to one side of the valve body 17, and the upper end of the 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, driving the valve body 17 to connect the inlet pipe 15 and the outlet pipe 16. When the trigger 14 is released, the pressure spring 18 returns to its original deformation and drives the valve body 17 to close the inlet pipe 15 and the outlet pipe 16.

[0048] In this embodiment of the invention, the coordination of the trigger 14, the pressure spring 18, and the valve body 17 facilitates opening the valve body 17 by pressing the trigger 14 to connect the inlet pipe 15 and the outlet pipe 16, reducing the user's hand strain. Simultaneously, when the user releases the trigger 14, the pressure spring 18 returns to its normal deformation, causing the trigger 14 to close the inlet pipe 15 and the outlet pipe 16.

[0049] It should be noted that the valve body 17 controlling the connection or closure of the inlet pipe 15 and the outlet pipe 16 is existing technology, and this utility model embodiment will not be described in detail here.

[0050] Please combine Figure 3 and Figure 4 As shown, specifically, the stop assembly 12 includes a slider 121, a slider 122, and a slide rail 123. The slide rail 123 is fixed inside the housing 11, the slider 122 is slidably connected to the slide rail 123, and the slider 121 is engaged with the slider 122 and exposed outside the housing 11. The user can move the slider 122 by operating the slider 121. The slide rail 123 has a movable groove 1231. The force-saving hook assembly 13 includes a first end and a second end, wherein the second end of the force-saving hook assembly 13 is located in the movable groove 1231. When the slider 121 is subjected to external force, it can cause the slider 122 to move closer to or further away from the second end of the force-saving hook assembly 13, thereby switching between the first, second, and third states.

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

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

[0053] In this embodiment of the utility model, the first state, the second state and the third state are quickly switched by the cooperation of a simple slider 121, a slider 122 and a slide rail 123. It is easy to understand and convenient to operate, which can avoid user misoperation and facilitate the assembly and disassembly of the water gun 1.

[0054] Please combine Figure 2 , Figure 5 and Figure 6 As shown, specifically, the effort-saving hook assembly 13 includes a supporting post 131, a rotating shaft 132, a movable hook 133, and a tension spring 134. The first end of the effort-saving hook assembly 13 is the movable hook 133, and the second end is the supporting post 131. Both ends of the rotating shaft 132 are movably disposed on the inner wall of the housing 11 so that the rotating shaft 132 can rotate around its central axis. The supporting post 131 and the movable hook 133 are disposed 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 included angle between the supporting post 131 and the movable hook 133 is 30° to 90°. For example, the included angle is 30°, 45°, 90°, etc. By limiting the included angle between the supporting post 131 and the movable hook 133, the space can be utilized to the maximum extent within the limited space inside the housing 11 of the water gun 1, thereby improving the space occupancy rate of the housing 11.

[0056] In this embodiment of the invention, under the action of the supporting post 131, the rotating shaft 132, the movable hook 133, and the tension spring 134, the trigger 14 and the stop assembly 12, which are not in the same plane, are made to cooperate, thereby completing the water spray state changes of the water gun in the first, second, and third states. 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, the trigger 14 has a groove 141, which is divided into a limiting area 142, an active 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 near the stop assembly 12 to the groove 141 away from the stop assembly 12). The self-locking area is provided with a self-locking structure 19.

[0058] It is understandable that, since the abutment post 131 and the movable hook 133 are located on the side of the rotating shaft 132, the stop assembly 12 gradually approaches the abutment post 131 in the first, second, and third states. At this time, 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 stop assembly 12 to the groove 141 approaching the stop assembly 12). Therefore, by defining the order of the limiting area 142, the movable area 143, and the self-locking area 144, it can be coordinated with the state changes of the stop assembly 12 to adapt to the water spray state changes 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 edge of the groove 141 in the limiting area 142 and the edge of the groove 141 in the moving area 143 have a smooth corner transition. This configuration allows for a natural transition between the second and third states, preventing jamming when the trigger 14 is pulled.

[0061] In this embodiment of the utility model, 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 active area 143 and the active hook 133, without the need for the cooperation of other parts, making the overall structure of the water gun 1 simpler.

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

[0063] Preferably, the edge of the groove 141 in the self-locking region 144 and the edge of the groove 141 in the active region 143 have a smooth transition. This arrangement makes the switching between the first and second states smoother.

[0064] Specifically, when the gear shift assembly 12 switches to the first state, there is a play between the second end of the effort-saving hook assembly 13 and the gear shift assembly 12. The first end of the effort-saving hook assembly 13 is located in the self-locking zone 144. When the trigger 14 is pulled, the first end of the effort-saving hook assembly 13 can move within the self-locking zone 144 due to the play. When the trigger 14 is released, the first end of the effort-saving hook assembly 13 locks with the self-locking structure 19 to achieve self-locking of the trigger 14. Pulling and releasing the trigger 14 again releases the first end of the effort-saving hook assembly 13 from the self-locking structure 19. This solves the problem that traditional water guns are very laborious to use, and may even injure fingers. Furthermore, prolonged trigger pressing can cause hand fatigue and a poor user experience. Through the cooperation between the gear shift assembly 12, the effort-saving hook assembly 13, and the trigger 14, the water gun 1 achieves a self-locking function, thus preventing hand fatigue caused by prolonged trigger pressing. The user does not need to forcefully pull the trigger 14; they only need to hold the water gun 1 to spray water, thereby achieving the purpose of saving effort.

[0065] Specifically, when the gear shift assembly 12 switches to the second state, the second end of the effort-saving hook assembly 13 abuts against the gear shift assembly 12, causing the first end of the effort-saving hook assembly 13 to be located in the movable area 143. When the trigger 14 is pulled and released, the first end of the effort-saving hook assembly 13 can move freely within the movable area 143. This allows the user to freely switch between the effort-saving state and the normal state, enabling water spraying when the trigger 14 is held down and stopping when released. This allows users to choose the normal state for water spraying during short-term operation, greatly improving the ease of use and practicality of the water gun 1 and enhancing the user experience.

[0066] Specifically, when the gear shift assembly 12 switches to the third state, the second end of the effort-saving hook assembly 13 abuts against the gear shift assembly 12, causing the first end of the effort-saving hook assembly 13 to be located in the limiting area 142. The first end of the effort-saving hook assembly 13 abuts against the trigger 14, so that the trigger 14 is fixed relative to the housing 11, thereby preventing the trigger 14 from being pulled. This provides an extra layer of safety for the water gun 1, preventing accidental triggering by the user that could cause the water gun 1 to spray water and cause injury, thus improving the safety of using the water gun 1.

[0067] It is understandable that the first state is the effort-saving state, in which the user uses water gun 1 with very little effort. The second state is the normal state, in which the user uses water gun 1, pulling trigger 14 sprays water, and releasing trigger 14 stops spraying water. The third state is the locked state, in which trigger 14 cannot be pulled, and 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, with the step 1442 corresponding to the opening of the arc-shaped bayonet 1441.

[0069] In the first state, there is a play between the holding post 131 and the stop assembly 12. When the trigger 14 is pulled, the movable hook 133, under the action of the tension spring 134 and the step 1442, hooks onto the arc-shaped latch 1441. When the trigger 14 is released, the movable hook 133 locks onto the arc-shaped latch 1441 to achieve self-locking of the trigger 14. When the trigger 14 is pulled and released again, the movable hook 133, under the action of the tension spring 134 and the step 1442, disengages from the arc-shaped latch 1441 to release the lock. The self-locking structure 19 formed by the arc-shaped latch 1441 and the step 1442 achieves the locking and releasing of the trigger 14. The structure is simple, reduces manufacturing costs, reduces the failure rate, and improves the overall reliability of the water gun 1.

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

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

[0072] Preferably, the step 1442 is located on the center line of the arc-shaped latch 1441. This design ensures that when the trigger 14 is pulled and released again, the trigger 14 successfully disengages from its self-locking mechanism.

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

[0074] Furthermore, an auxiliary ramp 1443 can be provided on the self-locking zone 144, with the auxiliary ramp positioned close to the arc-shaped latch 1441. By providing the auxiliary ramp 1443, the height of the movable hook 133 can be raised and guided to the arc-shaped latch 1441 for locking, thereby improving the accuracy of the trigger 14's self-locking.

[0075] For ease of understanding, the operation process of the water gun 1 is described in this embodiment of the present invention, and should not be construed as limiting.

[0076] When using water gun 1, if the user needs to operate it for a long time, the slider 121 can be moved to the first state, i.e., the effort-saving state. At this time, there is a movable gap between the holding post 131 and the slider 122, and the holding post 131 can move in the movable groove 1231. The movable hook 133 is located on the self-locking area 144. Pulling the trigger 14, with the cooperation of the step 1442, the movable hook 133 is pulled into the arc-shaped latch 1441 by the tension spring 134 and hooked to achieve self-locking of the trigger 14. At this time, there is no need for the user to keep the trigger 14 pulled, and the water gun 1 can spray water continuously. If it is necessary to stop spraying water, simply pull the trigger 14 again. With the cooperation of the step 1442, the movable hook 133 will be pulled out of the arc-shaped latch 1441 by the tension spring 134. At this time, the user 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 slider 121 can be moved to the second state, i.e., the normal state. At this time, the abutment post 131 abuts against the slider 122, and the movable hook 133 is located on the movable area 143 and will not hook the trigger 14. Pulling the trigger 14 will cause the water gun 1 to spray water, and releasing the trigger 14 will stop the water gun 1 from spraying water.

[0078] If the user does not need to use the water gun 1, the slider 121 can be moved to the third state, i.e., the locked state. At this time, the abutment post 131 abuts against the slider 122, and the movable hook 133 is located on the limiting area 142 and abuts against the edge 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 can be combined in any way. For the sake of brevity, 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 embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
