[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are preferred embodiments of the present utility model and should not be considered as excluding other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] like Figures 1-4 As shown, this utility model provides an anti-tamper shower head, including a shower head body 100, the shower head body 100 including a shower head 110, a handle portion 120 and a connector portion 130, the connector portion 130 having an external thread and a limiting groove 131; a connecting sleeve 200, one end of the connecting sleeve 200 being adapted to connect to the shower head body 100, and the other end of the connecting sleeve 200 being adapted to connect to a water pipe 300; the connecting sleeve 200 having an internal thread corresponding to the external thread on the connector portion 130, and a limiting hole 210 corresponding to the limiting groove 131 on the side wall of the connecting sleeve 200; a limiting screw 220 being threaded into the limiting hole 210, a portion of the limiting screw 220 being adapted to insert into the limiting groove 131.

[0023] like Figure 1 As shown, the shower head body 100 includes a shower head 110, a handle portion 120, and a connector portion 130. The shower head 110 has a water outlet panel as the terminal for water flow output. The handle portion 120 connects the shower head 110 and the connector portion 130, and is suitable for the user to hold. The connector portion 130 is connected to the water pipe 300 through a connecting sleeve 200. Both the handle portion 120 and the connector portion 130 have hollow water passages to guide water flow from the water pipe 300 to the shower head 110. Figure 2 As shown, the connecting sleeve 200 is hollow inside, and includes an upper section suitable for connecting to the shower head body 100 and a lower section suitable for connecting to the water pipe 300; the connector 130 is provided with an external thread, and the connecting sleeve 200 is provided with an internal thread corresponding to the external thread on the connector 130. By inserting the connector 130 into the connecting sleeve 200 and rotating the shower head body 100, the threaded connection between the shower head body 100 and the connecting sleeve 200 can be achieved.

[0024] like Figure 3As shown, the connecting sleeve 200 also includes a water pipe connector 230. The water pipe connector 230 is hollow inside. One end of the water pipe connector is a water pipe insertion part 231, and the other end is provided with a first limiting protrusion 232. The connecting sleeve 200 has a limiting step 240 corresponding to the limiting protrusion. At the limiting step 240, the inner diameter of the connecting sleeve 200 is smaller than the diameter of the limiting protrusion. The water pipe insertion part 231 is suitable for insertion into the water pipe 300, such as... Figure 3 As shown, during installation, the water pipe 300 is inserted through the bottom opening of the connecting sleeve 200, and the water pipe connector 230 is inserted through the top of the connecting sleeve 200 and into the water pipe 300. The first limiting protrusion 232 on the water pipe connector 230 is restricted by the limiting step 240 inside the connecting sleeve 200, preventing the water pipe connector 230 from detaching from the bottom opening of the connecting sleeve 200, thus connecting the water pipe 300 to the connecting sleeve 200. Then, the shower head body 100 is inserted through the top opening of the connecting sleeve 200, connecting the shower head body 100 to the connecting sleeve 200. This completes the connection between the shower head body 100, the connecting sleeve 200, and the water pipe 300, allowing water to flow from the water pipe 300 through the shower head body 100.

[0025] like Figure 3 and Figure 4 As shown, a limiting groove 131 is also provided on the connector portion 130. In this embodiment, the limiting groove 131 is formed on the outer wall of the connector portion 130 and located outside the external thread area. A limiting hole 210 corresponding to the limiting groove 131 is provided on the side wall of the connecting sleeve 200. In this embodiment, the limiting hole 210 penetrates the cylinder wall of the connecting sleeve 200 radially. In other embodiments, the limiting through hole may also penetrate the cylinder wall of the connecting sleeve 200 in a non-radial direction. A limiting screw 220 is internally threaded into the limiting hole 210. The end of the limiting screw 220 is adapted to be inserted into the limiting groove 131, thereby interfering with the connector portion 130 in the direction in which the shower body 100 disengages from the connecting sleeve 200, so as to prevent the shower body 100 from disengaging from the connecting sleeve 200.

[0026] Compared with the prior art, the anti-disassembly shower head provided in this utility model embodiment, by setting a limiting screw 220 to connect the shower head body 100 and the connecting sleeve 200, prevents the shower head body 100 from moving relative to the connecting sleeve 200 in the disassembly direction when the limiting screw 220 is not disengaged from the limiting groove 131, thereby preventing the shower head body 100 from separating from the connecting sleeve 200. Therefore, it can prevent the user from arbitrarily removing the shower head body 100 from the connecting sleeve 200, and can effectively prevent the loss of the shower head body 100 and small parts inside the shower head.

[0027] In some preferred embodiments, a first sealing gasket 250 and a second sealing gasket 260 are provided between the connector 130 and the water pipe connector 230. By providing the first sealing gasket 250 and the second sealing gasket 260, the sealing performance when the connector 130 is connected to the water pipe connector 230 is improved, ensuring that water will not leak out from the gap between the water pipe connector 230, the connecting sleeve 200 and the connector 130.

[0028] In some preferred embodiments, a filter screen 270 is also included, which is located between the first sealing gasket 250 and the second sealing gasket 260, or the filter screen 270 is located inside the first sealing gasket 250. By providing the filter screen 270, the water flow input to the shower head body 100 can be filtered to prevent impurities from entering the shower head body 100 and clogging the water outlet holes on the water outlet panel.

[0029] In some preferred embodiments, the outer side of the water pipe connector 231 is provided with several annular protrusions. When the water pipe connector 231 is inserted into the water pipe 300, the annular protrusions can make the water pipe connector 231 and the water pipe 300 more tightly connected, increasing the difficulty of the water pipe connector 231 being separated from the water pipe 300.

[0030] In some preferred embodiments, a protective member 280 is further included, which is sleeved outside the water pipe connector 230, and one end of the protective member 280 is provided with a second limiting protrusion 281 corresponding to the limiting step 240. For example... Figure 3 and Figure 4 As shown, a protective element 280 is also provided inside the connecting sleeve 200. The protective element 280 is located outside the water pipe connector 230 so as to clamp the water pipe 300 together with the water pipe connector 230. On the one hand, it can further increase the difficulty of the water pipe 300 detaching from the water pipe connector 230. On the other hand, it can protect the connection between the water pipe 300 and the water pipe connector 230 to prevent this part from being damaged due to repeated bending during use.

[0031] In some preferred embodiments, a protrusion is formed on the first limiting protrusion 232 on the side opposite to the insertion portion, and the second sealing gasket 260 is sleeved on the protrusion.

[0032] In some preferred embodiments, the limiting joint portion 130 has multiple limiting grooves 131, which are arranged around the joint portion 130. By providing multiple limiting grooves 131, the limiting hole 210 and the limiting groove 131 can be matched at multiple angles, so that the limiting screw 220 can be inserted into the limiting groove 131 without requiring the shower body 100 and the connecting sleeve 200 to be at a specific angle, thus facilitating the installation of the shower head.

[0033] In some other preferred embodiments, the limiting groove 131 surrounds the connector portion 130 to form an annular groove on the outer wall of the connector portion 130. By setting the limiting groove 131 as an annular groove, the limiting hole 210 and the limiting groove 131 can form a corresponding relationship at any angle so that the limiting screw 220 can be inserted into the limiting groove 131, which facilitates the installation of the shower head.

[0034] In some preferred embodiments, the limiting screw 220 is a countersunk hexagonal screw. By selecting an unconventional screw model, the anti-tamper shower head provided by this application can only be disassembled with professional disassembly tools, which can further prevent users from disassembling it at will.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
