[0029] like Figures 1 to 9As shown, the utility model provides a shower head that is easy to replace the filter element, which includes a mounting frame 1, a shell 2, a filter element 3, a water outlet assembly 4, two semicircular clamping rings 5 ​​and two elastic reset parts 6. The shell 2 is slidably sleeved on the outside of the mounting frame 1. The mounting frame 1 is provided with a channel 7, a first installation cavity 8 and a second installation cavity 9 that are connected in sequence. One end of the filter element 3 is detachably mounted in the first installation cavity 8, and the water outlet assembly 4 is detachably mounted in the second installation cavity 9. The top of the water outlet assembly 4 is sleeved on the outside of the other end of the filter element 3. The two ports of 3 are respectively connected to the water outlet of the channel 7 and the water outlet flow channel of the water outlet assembly 4. The inner end outer wall of the water outlet assembly 4 is recessed with an annular groove 10. The top of the inner wall of the second installation cavity 9 is provided with an annular sliding groove 11. The annular groove 10 is provided corresponding to the annular sliding groove 11. The two semicircular snap rings 5 ​​are symmetrically slidably provided in the annular sliding groove 11. The two elastic reset members 6 are respectively provided in a one-to-one correspondence with the two semicircular snap rings 5. The two ends of the elastic reset member 6 are respectively provided with the middle outer wall of the semicircular snap ring 5 and the annular sliding groove 1 1 elastically interferes with the inner wall of the housing 2, and the outer wall of the mounting frame 1 is symmetrically provided with two opening and closing through holes 12 connected to the annular sliding groove 11. An opening and closing rod 13 is provided at both ends of the semicircular snap ring 5. The opening and closing rod 13 on one end of each semicircular snap ring 5 extends out of the mounting frame 1 through one opening and closing through hole 12, and the opening and closing rod 13 on the other end of each semicircular snap ring 5 extends out of the mounting frame 1 through another opening and closing through hole 12. The inner wall of the housing 2 is symmetrically provided with two opening and closing drive blocks 14, each opening and closing drive block 14 is clamped between the two Between the adjacent opening and closing rods 13 on the semicircular snap rings 5, the opening and closing drive block 14 can move between the adjacent opening and closing rods 13, and opening and closing drive inclined surfaces 15 are provided on both sides of the opening and closing drive block 14. The opening and closing drive inclined surfaces 15 on both sides of the opening and closing drive block 14 respectively slide and contact with the adjacent opening and closing rods 13; the elastic reset member 6 is used to apply a force to the semicircular snap ring 5 to extend into the annular groove 10; the opening and closing drive inclined surfaces 15 can drive the adjacent opening and closing rods 13 away from each other, so that the two semicircular snap rings 5 ​​move away from the annular groove 10.

[0030] In actual application, the filter element 3 and the water outlet assembly 4 are assembled in the first mounting cavity 8 and the second mounting cavity 9 of the mounting frame 1 in sequence, and the two semicircular snap rings 5 ​​are respectively extended into the annular groove 10 under the elastic force of the corresponding elastic reset parts 6, so that the semicircular snap rings 5 ​​are engaged with the annular groove 10. At this time, the two semicircular snap rings 5 ​​are close to each other (closed) to lock the water outlet assembly 4 on the mounting frame 1, and the adjacent opening and closing rods 13 are against the minimum distance position between the two opening and closing drive inclined surfaces 15 on the opening and closing drive block 14. When the filter element 3 and the water outlet assembly 4 need to be removed, the driving housing 2 slides relative to the mounting frame 1 (specifically: the driving housing 2 moves upward relative to the mounting frame 1), so that the opening and closing driving block 14 moves relative to the adjacent opening and closing rods 13, and the opening and closing driving inclined surfaces 15 on the opening and closing driving block 14 drive the adjacent opening and closing rods 13 away from each other, so that the two semicircular snap rings 5 ​​move away from each other (open) and compress the corresponding elastic reset parts 6 until the adjacent opening and closing rods 13 contact the maximum distance position between the two opening and closing driving inclined surfaces 15 on the opening and closing driving block 14, and the semicircular snap ring 5 moves out of the annular groove 10 to unlock the water outlet assembly 4. At this time, the water outlet assembly 4 and the filter element 3 can be removed from the mounting frame 1 in turn. In addition, after reinstalling the filter element 3 and the water outlet assembly 4, the rebound force of the elastic reset member 6 will drive the semicircular retaining ring 5 to extend into the annular retaining groove 10, and at the same time, the adjacent opening and closing rods 13 will resist the opening and closing driving inclined surface 15 of the opening and closing driving block 14, so that the adjacent opening and closing rods 13 close to each other will resist and slide against the opening and closing driving inclined surface 15 to drive the housing 2 to reset and move relative to the mounting frame 1, so that the utility model is stably in use. The utility model only needs to drive the housing 2 to slide relative to the mounting frame 1 to achieve the disassembly and assembly of the filter element 3 and the water outlet assembly 4. The operation is convenient and efficient, and the filter element 3 is easy to replace. The housing 2 has good integrity and beautiful appearance.

[0031] In this embodiment, the housing 2 and mounting frame 1 are slidably connected via a guide structure. Specifically, the guide structure comprises a guide post 16 and a guide sleeve 17. The guide post 16 is disposed on the inner wall of the housing 2 and / or the outer wall of the mounting frame 1. Correspondingly, the guide sleeve 17 is disposed on the outer wall of the mounting frame 1 and / or the inner wall of the housing 2. As the housing 2 slides relative to the mounting frame 1, the guide post 16 and guide sleeve 17 slide together, providing guidance. This not only improves the stability of the sliding movement of the housing 2 relative to the mounting frame 1 but also facilitates the proper positioning and assembly of the housing 2 and the mounting frame 1.

[0032] In this embodiment, a ball head cover 18 is externally threadedly connected to the end of the mounting frame 1 away from the water outlet assembly 4. A sliding travel space 19 is formed between the ball head cover 18 and the mounting frame 1. A limit plate 20 is provided on the inner wall of the housing 2, and the limit plate 20 is movably disposed within the sliding travel space 19. The ball head cover 18 is used to lock the external ball head to the mounting frame 1, so that the external ball head is connected to the channel 7. When the housing 2 slides relative to the mounting frame 1, the limit plate 20 moves within the sliding travel space 19. The sliding travel space 19 limits the movement of the limit plate 20, preventing the housing 2 from separating from the mounting frame 1, thereby improving the stability of the sliding of the housing 2 relative to the mounting frame 1.

[0033] In this embodiment, positioning posts 21 are protruding from the peripheral sidewalls of the water outlet assembly 4, and positioning slots 22 are formed on the peripheral sidewalls of the mounting frame 1, communicating with the second mounting cavity 9. The positioning posts 21 and the positioning slots 22 are adapted to fit together. When the water outlet assembly 4 is assembled on the mounting frame 1, the positioning posts 21 and the positioning slots 22 cooperate to improve the assembly position accuracy and stability of the water outlet assembly 4 and the mounting frame 1, preventing relative rotation between the water outlet assembly 4 and the mounting frame 1.

[0034] In this embodiment, a tapered guide groove 23 is formed on the peripheral sidewall of the mounting frame 1 and communicates with the positioning groove 22. The tapered guide groove 23 communicates with the second mounting cavity 9, and the positioning post 21 moves into the positioning groove 22 via the tapered guide groove 23. During the assembly of the water outlet assembly 4 on the mounting frame 1, the tapered guide groove 23 guides and corrects the positioning post 21, allowing the positioning post 21 to move accurately into the positioning groove 22, thereby achieving accurate installation of the water outlet assembly 4 and the mounting frame 1.

[0035] In this embodiment, a mounting post 24 is provided on the central outer wall of the semicircular retaining ring 5, and a guide hole 25 is provided on the peripheral side wall of the mounting frame 1. The mounting post 24 slides with the inner wall of the guide hole 25. As the semicircular retaining ring 5 reciprocates within the annular sliding groove 11, the mounting post 24 slides with the guide hole 25, thereby improving the operating stability of the semicircular retaining ring 5.

[0036] In this embodiment, the elastic reset member 6 is a spring, and the spring is sleeved outside the mounting post 24. The mounting post 24 plays a positioning role for the spring, facilitates the disassembly and assembly of the spring, and ensures the working stability of the spring.

[0037] In this embodiment, a tip portion 26 is provided at the free end of the opening and closing driving block 14. The provision of the tip portion 26 facilitates the insertion of the opening and closing driving block 14 between adjacent opening and closing rods 13, thereby facilitating the assembly of the housing 2 and the mounting frame 1.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
