[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] This utility model provides the following technical solution:

[0017] As attached Figure 1 As shown, this utility model discloses a shower head, including a shower head base 1 and a water spray element 2. A water inlet channel 3 is formed within the shower head base 1, and a water spray channel 4 is formed on the water spray element 2. One end of the water spray element 2 extends into the water inlet channel 3 and connects to the shower head base 1. A through hole 5 is formed at the end of the water spray element 2 extending into the water inlet channel 3, and the through hole 5 connects the water inlet channel 3 and the water spray channel 4 respectively. The water inlet channel 3 has a water inlet 6, and a filter assembly is disposed on the side of the water inlet channel 3 near the water inlet 6. The filter assembly includes a filter element. 7. Filter element mounting base 8 and filter element retaining ring 9. The water inlet channel 3 has a filter element mounting part 10. The cross-section of the filter element mounting part 10 is arranged in a two-stage stepped shape. The filter element retaining ring 9, filter element 7, and filter element mounting base 8 are arranged sequentially from the water inlet 6 towards the center of the shower head seat 1. The filter element 7 is fixed on the filter element mounting base 8. The filter element mounting base 8 is sealed to the inner wall of the water inlet 6. The filter element retaining ring 9 is interference-fitted with the inner wall of the water inlet 6. One side of the filter element retaining ring 9 limits the position of the filter element 7 on the filter element mounting base 8. Specifically, in this design, by setting a filter assembly in the water inlet channel 3 of the shower head seat 1, the water entering the shower head can be filtered, effectively removing impurities and particles from the water, ensuring the cleanliness of the sprayed water, preventing impurities from clogging the spray channel 4, and improving the spraying effect and service life of the shower head. Meanwhile, the two-stage stepped design of the filter element mounting section 10 ensures that the filter element retaining ring 9, filter element 7, and filter element mounting base 8 are securely installed in the water inlet channel 3, preventing them from falling off or loosening, thus guaranteeing the stability and reliability of the filtration assembly. Furthermore, the interference fit between the filter element retaining ring 9 and the inner wall of the water inlet 6 further enhances the sealing performance of the filtration assembly, preventing water from bypassing the filter element 7 and directly entering the water spray channel 4, ensuring the filtration effect.

[0018] Furthermore, the filter element mounting base 8 has a mounting groove 11, and the filter element 7 is disposed in the mounting groove 11. The cross-sectional shape of the filter element 7 is T-shaped. A sealing ring groove 12 is formed between the filter element 7 and the inner wall of the mounting groove 11. A sealing ring 13 is disposed in the sealing ring groove 12. The sealing ring 13 is in sealing contact with both the filter element 7 and the filter element mounting base 8. The mounting groove 11 has an opening 14 connecting to the water inlet channel 3 and a mounting opening 15 connecting to the water inlet 6. An annular limiting part 16 protrudes from the inner wall of the mounting groove 11 near the mounting opening 15, and the annular limiting part 16 limits the axial position of the filter element 7 in the mounting groove 11. Specifically, in this embodiment, by opening a mounting groove 11 on the filter element mounting base 8 and placing the filter element 7 in the mounting groove 11, the filter element 7 can be effectively fixed, preventing it from shaking or shifting during operation. Meanwhile, the filter element 7 has a T-shaped cross-section. This design not only increases the contact area between the filter element 7 and the mounting groove 11, improving the stability of the filter element 7 installation, but also allows the filter element 7 to be more firmly positioned within the mounting groove 11. Furthermore, by forming a sealing ring groove 12 between the filter element 7 and the inner wall of the mounting groove 11, and placing a sealing ring 13 within this sealing ring groove 12, the sealing performance between the filter element 7 and the filter element mounting base 8 is further enhanced, preventing water leakage from the gap between the filter element 7 and the mounting groove 11, thus ensuring the sealing performance and filtration effect of the filter assembly. In addition, the mounting groove 11 has an opening 14 connecting to the water inlet channel 3 and an installation port 15 connecting to the water inlet 6. This design facilitates the installation and removal of the filter element 7, making it easier for users to replace the filter element 7 and maintain the normal operation of the shower head. The annular limiting part 16 protruding on the inner wall of the mounting groove 11 near the mounting port 15 can limit the axial position of the filter element 7 in the mounting groove 11, preventing the filter element 7 from moving axially during installation, and further ensuring the stability and reliability of the filter element 7 installation.

[0019] Furthermore, a limiting end 17 protrudes from the outer ring of the filter element 7 near the water inlet 6, forming a stepped structure between the limiting end 17 and the portion of the filter element 7 near the water inlet 6. An annular limiting part 16 protrudes from the portion of the inner wall of the mounting groove 11 corresponding to the stepped structure, and the annular limiting part 16 is engaged and fixed with the limiting end 17. Specifically, in this embodiment, the engaging fit between the limiting end 17 and the annular limiting part 16 limits the position of the filter element 7, ensuring that the filter element 7 will not shift or loosen within the mounting groove 11 due to water flow impact or other external forces.

[0020] Furthermore, the filter element mounting part 10 has a primary mounting part 18 and a secondary mounting part 19. The filter element mounting base 8 and the filter element 7 are disposed in the secondary mounting part 19, and the filter element retaining ring 9 is disposed in the primary mounting part 18. The inner diameter of the filter element retaining ring 9 is smaller than the outer diameter of the filter element 7. Specifically, in this embodiment, this hierarchical design of the filter element mounting part 10 can better fix the filter element 7 and improve the stability of the filter element 7 installation. The filter element retaining ring 9 in the primary mounting part 18 has an inner diameter smaller than the outer diameter of the filter element 7. This design allows the filter element retaining ring 9 to tightly hold the filter element 7, preventing the filter element 7 from slipping or loosening during installation. The secondary mounting part 19 provides sufficient space for the filter element mounting base 8 and the filter element 7 to be placed, ensuring that the filter element 7 can perform its filtering function normally. At the same time, this hierarchical design also makes the replacement of the filter element 7 more convenient. Users only need to open the primary mounting part 18 to easily remove the filter element 7 for replacement without disassembling the entire shower head, greatly improving the convenience of use.

[0021] Furthermore, a sealing positioning seat 20 is provided between the spray nozzle 2 and the water inlet channel 3. The sealing positioning seat 20 is sealed to both the spray nozzle 2 and the water inlet channel 3 using sealing rings. A positioning end 21 protrudes from the spray nozzle 2, and a positioning hole 22 is provided on the inner wall of the water inlet channel 3. The positioning end 21 extends into the positioning hole 22 and connects with the inner wall of the water inlet channel 3. Specifically, in this embodiment, the design of the sealing positioning seat 20 further enhances the sealing performance of the shower head. The use of the sealing ring 13 ensures that there is no leakage at the connection between the spray nozzle 2 and the water inlet channel 3, guaranteeing stable water pressure during showering. Simultaneously, the cooperation between the positioning end 21 and the positioning hole 22 not only achieves precise positioning of the spray nozzle 2 but also increases the stability of the connection, preventing loosening or displacement caused by water flow impact. This design not only improves the durability of the shower head but also ensures that users can obtain a stable and comfortable showering experience during use.

[0022] Furthermore, the shower head holder 1 has an arc-shaped surface 23, on which a seat positioning through hole 24 is formed. Specifically, in this embodiment, a screw is installed in the seat positioning through hole 24 to fix the shower head holder 1 to the wall. This design makes the installation of the shower head more stable and less prone to shaking. The arc-shaped surface 23 reduces the sharp edges on the shower head holder 1, avoiding injury to the user during installation and use, and improving product safety and user experience.
