[0017] Specifically, the movable shell is sequentially connected with a flow guide sleeve and a pattern disc, the first water outlet hole and the second water outlet hole are arranged on the pattern disc in an interval, the first butt joint part arranged on the flow guide sleeve communicates the first water outlet hole, the second butt joint part arranged on the movable shell communicates the second water outlet hole, the overflow port on the gun core can be aligned with the first butt joint part or the second butt joint part with the movement of the movable shell, so that the water channel in the gun core can be communicated with different water outlet ports, and the sprayed water flow of the water gun head can be changed by relatively moving the gun core and the movable shell, and the water gun head provided by the application is simple to operate and convenient for users to use.

[0018] 2. The overflow port on the gun core provided by the present invention is provided with a first sealing ring and a second sealing ring on both sides. Since multiple first protrusions and multiple second protrusions are respectively arranged at intervals on the inner walls of the first docking part and the second docking part, when the overflow port is docked with the first docking part or the second docking part, one of the first sealing rings and the other of the second sealing rings will abut against the protrusion and the other against the inner wall of the movable housing. At the same time, since there is a gap between adjacent protrusions, when the sealing ring abuts against the protrusion, it will not block the water flow from the docking part, while the other sealing ring abuts against the inner wall of the movable housing can close the channel for water flow to the other docking part. This ensures that the water flow from a single channel can be ensured when the water gun head switches water flow channels, improving the functional stability of the water gun head, and also preventing the water flow from flowing out from multiple water outlets, which would reduce the water flow intensity.

[0019] 3. The movable housing provided by the present invention is sleeved on the gun core and the two are rotatably connected by external and internal threads. Rotating the movable housing can make the movable housing and the gun core move relative to each other in a direction away from or close to each other. The threads can more accurately control the relative displacement distance between the movable housing and the gun core, so as to switch and adjust the water flow channel in the water gun head.

[0020] 4. The gun core provided by the present invention includes a first gun body and a second gun body connected together. A limiting part is provided on the second gun body and a first locking block is provided at both ends of the limiting part. A second locking block is provided on the outer wall of the movable shell. When the movable shell moves and the second locking block comes into contact with the first locking block, the second locking block can lock with the first locking block. The locking of the second locking block and the first locking block can prevent the movable shell from moving too far away from the gun core and thus disengaging from the gun core, and also prevent the movable shell from moving too far towards the gun core and thus rubbing and colliding with the gun core.

[0021] 5. The water gun head provided by the present invention also includes a piston that is movably placed in the second gun body. The piston can abut against the inner wall of the second gun body to close the water channel. The water channel inside the water gun head can be opened or closed by moving the piston.

Furthermore, a pull rod is also connected to the piston. The pull rod is at least partially exposed relative to the gun core. The piston is moved by the pull rod, which facilitates user operation and use.

[0023] 7. The first water outlet provided by the present invention is located in the middle area of ​​the color plate. The guide column on the gun core passes through the first water outlet. The water flowing out of the water gun head from the first water outlet is in the shape of a water column.

[0024] 8. The present invention provides a third sealing ring between the color plate and the movable housing. The color plate and the movable housing are detachably connected. By disassembling and replacing different color plates, the water gun head can flow out water in different patterns. At the same time, the third sealing ring can prevent the disassembly of the color plate from affecting the sealing performance of the structure.

[0025] 9. The movable housing provided by the present invention has anti-slip texture on its outer wall. Since the surface of the water gun head is usually wet during use, the anti-slip texture makes it easier to rotate the movable housing during use.

[0026] 10. To solve the above-mentioned technical problems, this utility model also provides a water gun, which includes a main housing and a water gun head, with the gun core placed inside the main housing. The water gun has the same beneficial effects as the water gun head mentioned above, which will not be described in detail here. [Attached Image Description]

[0055] As an embodiment, please refer to Figure 2 and Figure 3 , the outer wall of the gun core 11 is respectively sleeved with the first sealing ring 11211 and the second sealing ring 11212 corresponding to the two sides of the overflow port 1121, the first interface part 131 includes a plurality of first protrusions 1311 arranged annularly and spaced on the inner wall of the flow guide sleeve 13, and the first sealing ring 11211 abuts on the first protrusion 1311 when the overflow port 1121 and the first interface part 131 are at least partially connected; the second interface part 121 includes a plurality of second protrusions 1211 arranged annularly and spaced on the inner wall of the movable shell 12, and the second sealing ring 11212 abuts on the second protrusion 1211 when the overflow port 1121 and the second interface part 121 are at least partially connected.

[0056] Since the inner walls of the first interface part 131 and the second interface part 121 are respectively spaced with a plurality of first protrusions 1311 and a plurality of second protrusions 1211, there are gaps between adjacent first protrusions 1311 and between adjacent second protrusions 1211, and the first interface part 131 and the second interface part 121 can be respectively communicated with the first water outlet hole 141 and the second water outlet hole 142 through the gaps.

[0077] 5、The water gun head further comprises the piston movably arranged in the second gun body, the piston can abut against the inner wall of the second gun body to close the water channel, and whether to open the water channel in the water gun head can be controlled by moving the piston.

[0078] 6. The piston and the second gun body provided by the present invention are connected by a threaded rotation. The thread makes it easy to control the relative position of the piston and the second gun body, while ensuring the sealing stability of the water channel in the second gun body by the piston. Furthermore, a pull rod is also connected to the piston. The pull rod is at least partially exposed relative to the gun core. The piston is moved by the pull rod, which facilitates user operation and use.

[0079] 7. The first water outlet provided by the present invention is located in the middle area of ​​the color plate. The guide column on the gun core passes through the first water outlet. The water flowing out of the water gun head from the first water outlet is in the shape of a water column. The guide column can better guide the water flow in the water gun head to ensure the strength of the outflowing water.

[0080] 8. The present invention provides a third sealing ring between the color plate and the movable housing. The color plate and the movable housing are detachably connected. By disassembling and replacing different color plates, the water gun head can flow out water in different patterns. At the same time, the third sealing ring can prevent the disassembly of the color plate from affecting the sealing performance of the structure.

[0081] 9. The movable housing provided by the present invention has anti-slip texture on its outer wall. Since the surface of the water gun head is usually wet during use, the anti-slip texture makes it easier to rotate the movable housing during use.

[0082] 10. To solve the above-mentioned technical problems, this utility model also provides a water gun, which includes a main housing and a water gun head, with the gun core placed inside the main housing. The water gun has the same beneficial effects as the water gun head mentioned above, which will not be described in detail here.

[0083] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
