The width of the buckling part 22422 is smaller than that of the connecting part 22421. Before buckling, the connecting part 22421 and the buckling part 22422 are located on the same plane and are perpendicular to the limiting part 2241. After the rotating support 222 is installed with the fixed support 221, the buckling part 22422 is bent and makes the buckling part 22422 and the connecting part 22421 perpendicular as much as possible. After being completely bent, the buckling part 22422 is embedded in the containing groove 2214. The recessed parts 22423 are arranged to make the buckling part 22422 more easily bent. After the buckling part 22422 is embedded in the containing groove 2214, it can play a certain limiting role and can also prevent the buckling part 22422 from being too high above the end surface of the fixed support 221. In order to better install the fixing part 224, four first buckles 2242 are arranged, and the limiting part 2241 is sleeved outside the rotating part 2222 of the rotating support 222.

[0077] For details, please refer to Figure 8 、 9 The fixing part 224 further includes a second buckle 2243 for installing the first circuit board 242. Specifically, the second buckle 2243 can be bent after passing through the first circuit board 242. The fixed support 221 is provided with a plurality of support tables 2215 for supporting the first circuit board 242 and a plurality of positioning columns 2216 for positioning the installation of the first circuit board 242. The positioning column 2216 includes a supporting part 22161 and a positioning part 22162 arranged on the supporting part 22161. After the first circuit board 242 is installed, the support tables 2215 and the supporting parts 22161 play a supporting role, and the positioning parts 22162 play a positioning role. Specifically, four support tables 2215 and three positioning columns 2216 are arranged to better support and position the first circuit board 242.

[0078] For details, please refer to Figure 3 After the magnetic ring 223 is installed, it is fixed by arranging a clamping protrusion 22213 on the mounting part 2221. Specifically, the clamping protrusion 22213 is formed by melting in a hot pressing manner, and a plurality of clamping protrusions 22213 can be arranged according to needs.

[0079] The faucet body further comprises a faucet shell, a mounting piece arranged on the faucet shell, and the mounting piece is used for mounting the control device 20, that is, the mounting position 11 is arranged on the mounting piece, specifically, a limiting step is arranged on the outer circumference of the mounting piece, a limiting groove for cooperating with the limiting step is arranged on the faucet shell, three mounting pieces are arranged in the utility model, a fifth clamping hook is arranged on the mounting piece, a clamping groove for cooperating with the fifth clamping hook is arranged on the faucet shell, when the control device 20 is mounted to the mounting piece, the control device 20 can be mounted on the faucet shell, modular installation is realized, installation efficiency is improved, and a sealing ring is arranged between the outer side of the mounting piece and the rotary support seat 231 to achieve a sealing effect.

[0080] In summary, the faucet control structure can control water temperature through the encoder, can flow out drinking water with a required temperature, and meets more requirements. Specifically, the rotary assembly is rotated to control the encoder to work, and the encoder can correspondingly output a specific temperature, and drinking water with the required temperature can be correspondingly output when rotating to a specified position.

[0081] The utility model is described above in combination with the drawings, obviously, the utility model is not limited by the above-mentioned mode in the specific implementation, and various non-essential improvements adopting the method concept and technical scheme of the utility model or directly applying the concept and technical scheme of the utility model to other occasions without improvement are all within the protection scope of the utility model.
