DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] Example 1:

[0035] like Figures 1 to 7 As shown, a shower head with filtering function includes:

[0036] The shower body 10 has a water inlet channel 11, a water outlet channel 12 and a water outlet panel 13 which are connected in sequence;

[0037] The filter element 20 is movably arranged in the shower body 10. The filter element 20 is provided with a raw water channel 21 and a filter channel 22. The filter channel 22 is provided with filter material. The filter element 20 is also provided with a sealing portion 23. The shower body 10 is correspondingly provided with a matching portion. The preferred solution for the filter material is a carbon fiber filter element 20 or a PP cotton filter element 20.

[0038] The movable member 30 is movably mounted on the shower body 10 and is in transmission cooperation with the filter element 20;

[0039] When the movable part 30 drives the filter element 20 to move to the first position, the sealing part 23 is sealed and matched with the matching part, thereby closing the raw water channel 21, and the water in the water inlet channel 11 flows through the filter channel 22 and then flows to the water outlet channel 12. When the filter element 20 is reset to the second position, the sealing part 23 is separated from the matching part, thereby opening the raw water channel 21, and the water in the water inlet channel 11 flows through the raw water channel 21 to the water outlet channel 12.

[0040] In this embodiment, an elastic member 40 is further included to provide elastic force to the filter element 20 , and the filter element 20 can be reset to the second position under the action of the elastic member 40 .

[0041] In this embodiment, the filter element 20 includes a hollow inner shell 24 and a hollow outer shell 25. The hollow cavity of the inner shell 24 forms the raw water channel 21. An annular cavity is formed between the inner shell 24 and the outer shell 25, and the annular cavity forms the filter channel 22.

[0042] In this embodiment, a plurality of water inlet holes 26 are provided on the peripheral wall of the outer shell 25 , and both ends of the annular cavity are closed.

[0043] In this embodiment, the sealing portion 23 is arranged at one end of the filter element 20 close to the water inlet channel 11, and the matching portion is a slot 14 arranged on one side close to the water inlet channel 11. The sealing portion 23 cooperates with the slot 14 to close the end of the raw water channel 21 close to the water inlet channel 11.

[0044] In this embodiment, the movable part 30 is slidably arranged, and a rotatable rotating part 50 is further provided in the shower body 10. The rotating part 50 is provided with a driving part 51, and the movable part 30 is provided with a guide inclined surface 31. The driving part 51 cooperates with the guide inclined surface 31 to drive the movable part 30 to slide.

[0045] In this embodiment, the movable member 30 is provided with a guide groove 32 , and the shower body 10 is provided with a guide rib. The guide groove 32 and the guide rib are in guiding and sliding cooperation.

[0046] In this embodiment, a rotatable switching ring 60 is further provided on the shower body, and the switching member is circumferentially limitedly engaged with the rotating member 50 .

[0047] like Figure 6 As shown, a sealing portion 23 is provided at the rear end of the filter element 20. When the filter element 20 is in the first position, the sealing portion 23 is sealed and connected to the slot 14. At this time, water enters the water inlet channel 11 after the shower head enters. After that, since the raw water channel 21 is closed, the water flow can only be filtered by the filter element 20 to form clean water outlet.

[0048] like Figure 7 As shown, when the filter element 20 is in the second position, the sealing portion 23 is separated from the slot 14. At this time, the water enters the water inlet channel 11 after the shower head enters. After that, since the raw water channel 21 is opened, due to the effect of the filter material pipe resistance in the filter channel 22, the water flow does not need to be filtered by the filter element 20 and directly enters the raw water channel 21, forming raw water outlet.

[0049] This solution realizes the switching between raw water and purified water by driving the filter element 20 to move, which makes the structure simple, the function stable and the cost low.

[0050] Example 2:

[0051] like Figure 8 As shown, the main difference between this embodiment and the above embodiment is that a plurality of anti-fouling ribs 15 are provided on the inner wall of the shower body 10 at positions corresponding to the filter element 20. When the filter element 20 moves between the first position and the second position, the anti-fouling ribs 15 slide relative to the water inlet hole 26. By adding discontinuous anti-fouling ribs 15, when the filter element 20 moves, the anti-fouling ribs 15 can scrape off dirt on the surface of the filter element 20 to prevent the water inlet hole 26 from being blocked.

[0052] Other undescribed parts are consistent with those in the first embodiment and will not be described again here.

[0053] Example 3:

[0054] The main difference between this embodiment and the first embodiment is that the sealing portion 23 is arranged at one end of the filter element 20 close to the water outlet channel 12, and the matching portion is a slot 14 arranged on one side close to the water outlet channel 12. The sealing portion 23 cooperates with the slot 14 to close the end of the raw water channel 21 close to the water outlet channel 12.

[0055] In this embodiment, the gap between the outer shell 25 and the inner wall of the shower body 10 forms the raw water channel 21 .

[0056] like Figure 9 As shown, a sealing portion 23 is provided at the front end of the filter element 20. When the filter element 20 is in the first position, the sealing portion 23 is sealed and connected to the slot 14. At this time, water enters the water inlet channel 11 after entering the shower head. After that, since the raw water channel 21 is closed, the water flow can only be filtered by the filter element 20 to form clean water outlet.

[0057] like Figure 10 As shown, when the filter element 20 is in the second position, the sealing portion 23 is separated from the slot 14. At this time, the water enters the water inlet channel 11 after the shower head enters. After that, since the raw water channel 21 is opened, due to the effect of the filter material pipe resistance in the filter channel 22, the water flow does not need to be filtered by the filter element 20 and directly enters the raw water channel 21, forming raw water outlet.

[0058] Other undescribed parts are consistent with those in the first embodiment and will not be described again here.

[0059] The foregoing description shows and describes preferred embodiments of the present invention. As previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the inventive concept described herein by the teachings above or by techniques or knowledge in the relevant art. Modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention are intended to be within the scope of the appended claims.
