The related art provides a filter element connecting seat 10, the filter element connecting seat 10 is used for being installed in a water purification system and is connected with a water inlet pipe and a water outlet pipe of the water purification system, and a filter element 18 is further installed on the filter element connecting seat 10.

When the filter element 18 is replaced, the filter element connecting seat 10 is provided with a corresponding water stop structure for blocking a water outlet pipe and a water inlet pipe of the water purification system and preventing water flow in the water purification system from being sprayed out. However, the filter cartridge holder 10 in the prior art is often single-waterway, that is, when the filter cartridge 18 is replaced, the water flow at the filter cartridge holder 10 is partially stopped, which may affect the normal operation of the whole water purification system. Therefore, it is desirable to provide a cartridge receptacle 10 that does not partially shut down water when replacing the cartridge 18.

Referring to fig. 1 to 3, in order to solve the above problem, the present invention provides a filter cartridge holder 10 for mounting a filter cartridge 18, wherein the filter cartridge holder 10 includes a housing 11 and a waterway switching member 12. The shell 11 is provided with a first accommodating cavity, and the shell 11 comprises a water inlet 110 and a water outlet 111 which are communicated with the first accommodating cavity; the waterway switching piece 12 is movably installed in the first accommodating cavity, the waterway switching piece 12 includes a first flow channel 121, a second flow channel 122 and a third flow channel 123, one end of the first flow channel 121 is used for communicating with the water inlet 110 of the filter element 18, and one end of the second flow channel 122 is used for communicating with the water outlet 111 of the filter element 18; the waterway switching member 12 moves relative to the housing 11 to have a first position and a second position, when the waterway switching member 12 is in the first position, the other end of the first flow channel 121 is communicated with the water inlet 110 of the housing 11, and the other end of the second flow channel 122 is communicated with the water outlet 111 of the housing 11; when the waterway switching member 12 is located at the second position, two ends of the third flow channel 123 are respectively communicated with the water inlet 110 of the housing 11 and the water outlet 111 of the housing 11. When the filter element connecting seat 10 is connected to a water purification system, an external water inlet channel is communicated with the water inlet 110 of the shell 11, and an external water outlet channel is communicated with the water outlet 111 of the shell 11. That is, the water flow from the external water inlet channel through the filter element seat 10 continues to flow into the external water outlet channel, and the water path is not interrupted by replacing the filter element 18. When water needs to be filtered, the filter element 18 is mounted on the filter element seat 10, the waterway switching member 12 is in the first position, and water flows into the filter element 18 from the first flow passage 121, is treated, and then flows out from the second flow passage 122. When the filter element 18 is replaced or the filtering is not needed, the waterway switching member 12 is only required to be switched to the second position, so that the water flowing from the water inlet 110 of the housing 11 directly passes through the third flow channel 123 without passing through the filter element 18, and flows out from the water outlet 111 of the housing 11. In a preferred embodiment, the cartridge seat 10 is provided with a third flow passage 123 in addition to the first flow passage 121 and the second flow passage 122 for communicating with the cartridge 18.

The waterway switching member 12 is movably installed in the housing 11, and there should be a gap between the waterway switching member 12 and the housing 11 for the waterway switching member 12 to move. In this way, the waterway switch 12 can rotate along the axis of the filter element 18 or move up and down along the axis of the filter element 18 in the first accommodating cavity, so as to switch the waterway switch 12 between the first position and the second position.

In an optional embodiment, the first accommodating cavity is a cavity formed by extending along the axial direction of the filter element 18, the shape of the waterway switching member 12 is adapted to the shape of the first accommodating cavity, the waterway switching member 12 is formed with a second accommodating cavity, a clamping portion for installing the filter element 18 is arranged in the second accommodating cavity, and the filter element 18 drives the waterway switching member 12 to rotate along the axial direction of the filter element 18 through the clamping portion. Specifically, the filter element 18 is mounted on the filter element connecting seat 10 through the second accommodating cavity. Further, the filter element 18 is provided with a clamping protrusion corresponding to the clamping portion. When the filter element 18 needs to be replaced, the filter element 18 only needs to be rotated, and the filter element 18 drives the waterway switching piece 12 to rotate through the clamping protrusion, so that the waterway switching piece 12 is switched between the first position and the second position.

In an alternative embodiment, a first retaining member 16 is disposed between an outer surface of the waterway switching member 12 and an inner wall of the receiving cavity, and the first retaining member 16 is used for preventing the waterway switching member 12 from moving relative to the housing 11 along the axial direction of the filter element 18. It should be noted that, in order to align the first flow passage 121, the second flow passage 122, and the third flow passage 123 with the water inlet 110 and the water outlet 111 of the housing 11, the present invention provides a method for manufacturing the same. So that the waterway switching piece 12 just achieves the switching between the first position and the second position when rotating. The first limiting member 16 is a limiting ring, the limiting ring is sleeved on the waterway switching member 12, and further, two sides of the limiting ring are respectively abutted against the inner wall of the housing 11 and the outer wall of the waterway switching member 12. In this way, the waterway switch 12 can only rotate, but cannot move up and down along the axial direction of the filter cartridge 18. This is one example of the waterway switch 12 being rotationally switched between the first position and the second position.

Referring to fig. 4 and 5, a second limiting member 17 is disposed between the waterway switching outer surface and the inner wall of the accommodating cavity, and the second limiting member 17 is used for limiting the rotation angle of the waterway switching member 12.

It should be noted that the first sealing member 13 and the third sealing member 15 are both O-ring seals, and the first sealing member 13 and the third sealing member 15 respectively seal the upper end and the lower end of the waterway switch 12, so as to prevent water in the third flow channel 123 from leaking when the waterway switch 12 is at the second position. The second sealing member 14 is a profiled sealing member, and the second sealing member 14 is used for preventing the water flow in the first flow passage 121 and the second flow passage 122 from leaking when the waterway switching member 12 is at the first position.

In an alternative embodiment, the filter cartridge holder 10 includes an elastic member disposed in the first accommodating cavity, the elastic member connects the waterway switching member 12 and the housing 11, when the filter cartridge 18 is installed, the elastic member is pressed to make the waterway switching member 12 in the first position, and when the filter cartridge 18 is removed, the elastic member is elastically deformed to make the waterway switching member 12 in the second position. In an alternative embodiment, the waterway switch 12 may also switch between the first position and the second position by moving up and down. Optionally, the elastic member is a spring. The waterway switching member 12 does not rotate, and an accommodating space is formed between the top of the waterway switching member 12 and the inner wall of the housing 11, and the spring is arranged in the accommodating space.
