[0002] A water spray gun is a commonly used water spraying tool that can be widely used in vehicle washing, building cleaning, garden and lawn watering, etc.

[0003] In the existing technology, portable or wireless water spray guns are generally powered by batteries. Some water spray guns also store electrical energy through batteries and charging sockets. When the water spray gun has a power supply problem, the conventional method is to take the entire water spray gun for repair. This troubleshooting method is relatively inconvenient and may even damage other functional modules of the water spray gun. It is highly uncontrollable. In fact, to solve this problem, in the existing technology, the power supply device is often integrated into the handle of the water spray gun. When the user needs to test the power supply device, the handle can be disassembled and tested separately. However, in order to ensure the stability of the connection between the handle and other structures of the water spray gun, the handle and the gun body of the water spray gun are generally integrated or assembled very stably, which is inconvenient for users to replace or disassemble, and the difficulty of testing is also increased. Therefore, there is room for improvement. Utility Model Content

[0025] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] The present utility model provides a water gun with an easily replaceable energy supply device. Please refer to Figures 1-9 , the water gun includes a gun body 1, a water gun handle 2, and other components that meet the normal operation of the structure, such as a liquid storage bottle, a nozzle, and a water pipe, etc. The gun body 1 includes a gun body module 11 and a holding module 12 inclined outside the gun body module 11. At least one clamping portion 13 is provided on the circumferential side of the bottom end of the holding module 12. A battery is provided inside the water gun handle 2 for supplying energy. At least one engaging portion 23 is provided at the top end of the water gun handle 2. An insertion pin 1231 that can rotate around the axis direction of the gun body module 11 is provided at the bottom end of the gun body module 11. A socket hole 22 for inserting the insertion pin 1231 is provided at the top end of the water gun handle 2.

[0027] Among them, after the socket hole 22 of the water gun handle 2 is inserted into the insertion pin 1231, rotate the water gun handle 2 to make the clamping portion 13 engage with the matching engaging portion 23, so as to achieve the rapid assembly of the water gun handle 2 and the gun body 1. The above setting makes the assembly of the water gun handle 2 and the gun body 1 convenient, and for the cleaning personnel, the assembly steps are few, and the cleaning personnel can quickly replace the water gun handle 2.

[0028] Regarding the above-mentioned structures involved, the following will be described in detail.

[0029] In this embodiment, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 , a ring-shaped shaft 121 with a shaft hole is provided along a straight line at the bottom end of the holding module 12. The shaft hole is used for inserting the structure on the top end of the water gun handle 2. Among them, an installation channel 122 coaxial with and communicating with the shaft hole is provided at the bottom end of the holding module 12. An annular groove 1221 is recessed on the inner wall surface of the installation channel 122. An insulating structure body 123 that can rotate by itself is fitted in the annular groove 1221. The insertion pin 1231 is provided on the insulating structure body 123. A socket for fitting with the hole of the ring-shaped shaft 121 is provided at the top end of the water gun handle 2. The socket hole 22 is provided at the top end of the socket, and the socket hole 22 and the insertion pin 1231 can be inserted.

[0030] Regarding the insertion of the pin 1231 into the socket 22, the socket is inserted into the shaft hole on the annular shaft 121, so that the pin 1231 on the insulating structure 123 is inserted into the matching socket 22. In this embodiment, the insulating structure 123 is in the shape of a circular sheet, and the insulating structure 123 can rotate self - sufficiently within the annular channel 1221. Therefore, when the cleaning personnel rotate the water gun handle 2, the insulating structure 123 rotates within the annular channel 1221 under the influence of the pin 1231 being driven to rotate by the socket 22, thereby adjusting the positions of the engaging portion 23 on the water gun handle 2 and the engaging portion 13 on the holding module 12 so that they can be engaged.

[0031] To accurately and quickly engage the engaging portion 23 with the corresponding engaging portion 13, a limiting arc channel 1222 is recessed on the side surface of a part of the inner wall of the annular channel 1221, and a limiting shaft 1232 is provided on the outer peripheral surface of the insulating structure 123. The end of the limiting shaft 1232 is located within the limiting arc channel 1222. That is, the limiting arc channel 1222 restricts the movement path of the limiting shaft 1232, thereby restricting the number of turns of the insulating structure 123. In this embodiment, when the insulating structure 123 rotates less than half a turn, the engaging portion 23 can be adaptively engaged with the engaging portion 13. This setting greatly reduces the assembly steps and does not require rotating multiple turns to thread - assemble the water gun handle 2 as in the prior art.

[0032] Regarding the engagement between the engaging portion 23 and the engaging portion 13, the following will be further described.

[0033] In this embodiment, the number of both the engaging portion 13 and the engaging portion 23 is two. Of course, in other embodiments, the number of the engaging portion 13 and the engaging portion 23 can be three, four, etc.

[0034] Specifically, please refer to Figure 5 and Figure 6 , the engaging portion 13 includes a first arc - shaped convex strip 131 and a second arc - shaped convex strip 132. The first arc - shaped convex strip 131 and the second arc - shaped convex strip 132 are arranged at intervals along the axial direction of the annular shaft 121 on the outer peripheral surface of the annular shaft 121, so that the interval between the first arc - shaped convex strip 131 and the second arc - shaped convex strip 132 forms a channel for engaging with the structural element in the engaging portion 23. Among them, a engaging member 1321 is provided on the surface of the second arc - shaped convex strip 132 facing the first arc - shaped convex strip 131 to ensure the stability of the engagement after the engaging portion 13 and the engaging portion 23 are engaged.

[0035] Further, please refer to Figure 7 and Figure 8, a clamping groove 21 is recessed at the top end of the water gun handle 2 along the inner direction of the water gun handle 2. The clamping portion 23 includes a clamping block 231 and a limiting column 232. One end of the limiting column 232 is connected to the bottom surface of the clamping groove 21, and the other end is connected to the bottom surface of the end of the clamping block 231, so as to suspend the clamping block 231 in the clamping groove 21. Among them, the side surface of the clamping block 231 is connected to or integrally formed with the inner wall surface of the clamping groove 21, so that a clamping slideway capable of accommodating the sliding of the second arc-shaped convex strip 132 is arranged between the bottom surface of the clamping block 231 and the bottom surface of the clamping groove 21. This clamping slideway restricts the second arc-shaped convex strip 132, and at the same time, the clamping block 231 is also restricted in the groove, thereby realizing the clamping and fixing of the clamping portion 13 and the clamping portion 23.

[0036] In this embodiment, please refer to Figure 6 and Figure 8 , the outer peripheral surface of the limiting column 232 includes a first side surface 2321, the first side surface 2321 is arranged facing the outer side surface of the socket, an inclined second side surface 2322 is arranged at the side of the first side surface 2321, and the side of the second side surface 2322 far from the first side surface 2321 is connected to the inner wall surface of the clamping slideway. This second side surface 2322 is used to fit and abut against the end of the second arc-shaped convex strip 132 sliding into the clamping slideway to restrict the position of the second arc-shaped convex strip 132.

[0037] In this embodiment, please refer to Figures 5-8 , a discharge slideway communicating with the clamping slideway is arranged between the clamping portions 23 along the inner wall surface direction of the clamping groove 21. This discharge slideway is used to accommodate the second arc-shaped convex strip 132, so that when the water gun handle 2 rotates, the second arc-shaped convex strip 132 can slide into the clamping slideway.

[0038] A specific description is made on how the clamping portion 13 and the clamping portion 23 are clamped. When the pin 1231 is inserted into the jack 22, the second arc-shaped convex strip 132 is located in the inclined slideway. Then, the cleaning personnel slightly rotate the water gun handle 2. At this time, the second arc-shaped convex strip 132 enters the clamping slideway. When the end of the second arc-shaped convex strip 132 abuts against the second side surface 2322 on the limiting column 232, the water gun handle 2 cannot be rotated anymore, and the second arc-shaped convex strip 132 is restricted in the clamping slideway. At the same time, the clamping block 231 is also restricted in the groove, thereby completing the clamping of the clamping portion 13 and the clamping portion 23, and the water gun handle 2 is stably connected to the holding module 12; when the water gun handle 2 needs to be replaced, the cleaning personnel only need to rotate the water gun handle 2 in the opposite direction of the original rotation direction, the second arc-shaped convex strip 132 slides into the inclined slideway, and then the pin 1231 is pulled out. At this time, the water gun handle 2 is separated from the holding module 12. The above operation steps are few, and the cleaning personnel do not need to use much force, so that the water gun handle 2 can be quickly replaced.

[0039] Substantially, to ensure that the second arc-shaped protrusion 132 is stably restricted within the engaging slideway, a boss that fits with the engaging member 1321 is provided at the bottom end of the engaging block 231. Through the cooperation of the boss and the engaging member 1321, the stability of the assembly of the water gun handle 2 and the holding module 12 is further enhanced.

[0040] In this embodiment, the cross-section of the engaging member 1321 is triangular. One side surface of the engaging member 1321 is connected to or integrally formed with the outer peripheral surface of the annular shaft 121, and the other side surface of the engaging member 1321 is an arc surface, which fits with the bottom surface of the boss.

[0041] Furthermore, in the present utility model, please refer to Figure 9 , the water gun handle 2 includes a handle shell, and a rubber pad 24 is provided on the outer side of the handle shell. This setting facilitates the cleaning personnel to hold and enhances the comfort of the cleaning personnel's hand grip.

[0042] Specifically, the water gun handle 2 further includes a button assembly 25. A keyhole is provided on the outside of the handle shell, and the keyhole is located below the rubber pad 24. The button assembly 25 is installed in the keyhole. This setting prevents the cleaning personnel from accidentally touching the button when holding the water gun handle 2, causing unnecessary working conditions.

[0043] In this embodiment, a limiting protrusion 26 extends along the outer direction at the bottom end of the handle shell. On the one hand, the limiting protrusion 26 prevents the cleaning personnel from having the situation of the water gun handle 2 slipping out of the hand, and on the other hand, it also ensures the position where the cleaning personnel holds the water gun handle 2.

[0044] Finally, in this embodiment, a USB socket is provided at the bottom end of the water gun handle 2 for charging and supplying energy to the battery inside the water gun handle 2. Secondly, this design also prevents the USB socket from being immersed in water, causing safety accidents.

[0045] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; under the idea of the present utility model, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other variations in different aspects of the present utility model as described above. For the sake of simplicity, they are not provided in detail; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
