Filter element and water purifier

Abstract

The application discloses a filter element and a water purifier. When the filter element and the water purifier are used, the first switch element can be driven to move, so that the first switch element and the inner wall of the first installation channel form a third water flow channel which is communicated with the first water flow channel, and the second switch element and the second installation channel form a fourth water flow channel which is communicated with the second water flow channel. The first water flow channel can be a raw water channel, and the second water flow channel can be a pure water channel. Raw water can enter the first water flow channel, and then the pure water obtained by filtering the raw water through the filtering element can enter the second water flow channel and be discharged, so that the normal filtering function of the filter element is realized. When the filter element needs to be replaced, the first switch element is reset to be in sealing cooperation with the inner wall of the first installation channel, so as to block the first water flow channel. Meanwhile, the first switch element is in sealing cooperation with the second switch element, so as to block the second water flow channel. Therefore, the water in the accommodating cavity cannot be discharged, and the residual water in the filter element can be prevented from spilling out.

Claims

1. A filter element, characterized in that, include: The mounting housing has a receiving cavity and a first mounting channel communicating with the receiving cavity; A filter element, wherein the filter element is installed within the receiving cavity and the filter element is spaced apart from the inner wall of the receiving cavity to form a first water flow channel, and a second water flow channel is formed within the filter element; and A valve assembly includes a first switch element, a second switch element, and a resilient reset element. The first switch element is movably disposed in the first mounting channel and forms a third water flow channel communicating with the first water flow channel. The first switch element is provided with a second mounting channel. The first switch element is connected to the filter element through the resilient reset element. One end of the second switch element is inserted into the second mounting channel and forms a fourth water flow channel communicating with the second water flow channel. The other end of the second switch element is connected to the filter element. When the valve assembly is in the first state, the first switching element moves relative to the first mounting channel and the second switching element to open the third water flow channel and the fourth water flow channel; When the valve assembly is in the second state, the elastic reset member resets and drives the first switch member to move until the first switch member and the inner wall of the first mounting channel are sealed together to close the third water flow channel. At the same time, the first switch member and the second switch member are sealed together to block the fourth water flow channel.

2. The filter element according to claim 1, characterized in that, The outer wall of the first switch is provided with a first sealing part, and the inner wall of the second mounting channel is provided with a second sealing part; When the valve assembly is in the first state, the first switching element is subjected to force and moves relative to the first mounting channel to open the third water flow channel and the fourth water flow channel. When the valve assembly is in the second state, the elastic reset member resets and drives the first switch member to move so that the first sealing part seals against the inner wall of the first mounting channel to close the third water flow channel, and the second sealing part seals against the second switch member to close the fourth water flow channel.

3. The filter element according to claim 2, characterized in that, The first sealing part is a first stepped part, the second sealing part is a sealing surface, the first mounting channel is provided with a second stepped part that limits and seals with the first stepped part, and the second switch is provided with a sealing protrusion that seals with the sealing surface.

4. The filter element according to any one of claims 1 to 3, characterized in that, It also includes a first seal and a second seal, wherein the first seal is disposed between the first switch and the inner wall of the first mounting channel, and the second seal is disposed between the inner wall of the second mounting channel and the second switch. When the valve assembly is in the first state, the first switching element moves to separate the first seal from the first switching element or from the inner wall of the first mounting channel, and to separate the second seal from the inner wall of the second mounting channel or from the second switching element. When the valve assembly is in the second state, the elastic reset member resets and drives the first switch member to move so that the first switch member is sealed with the first mounting channel through the first seal member, and the inner wall of the second mounting channel is sealed with the second switch member through the second seal member.

5. The filter element according to claim 1, characterized in that, The filter element includes a filter body and an installation assembly. The filter body is installed in the receiving cavity through the installation assembly. The installation assembly has a first water outlet. The filter body and the inner wall of the receiving cavity form a first water flow channel. The filter body also forms a second water flow channel. The second water flow channel can communicate with the fourth water flow channel through the first water outlet. The elastic reset member abuts against the other end of the first switch member and the installation assembly. The other end of the second switch member is fixed to the installation assembly.

6. The filter element according to claim 5, characterized in that, The installation assembly includes a first mounting component, one end of the filter body is connected to the first mounting component, the first mounting component is provided with the first water outlet, and the elastic reset component abuts between the first switch component and the first mounting component.

7. The filter element according to claim 6, characterized in that, The first mounting member has a first mounting portion, the first mounting portion having a first mounting groove, and the elastic reset member being disposed within the first mounting groove.

8. The filter element according to claim 7, characterized in that, The side wall of the first mounting part forms a second mounting groove, which is located within the area enclosed by the first mounting groove. The second mounting groove is connected to the first water outlet. The fourth water flow channel is connected to the second water flow channel through the second mounting groove and the first water outlet. The other end of the second switch is inserted into the second mounting groove.

9. The filter element according to claim 8, characterized in that, It also includes a third seal, wherein the first switch extends into the first mounting groove, and the third seal is disposed between the inner wall of the first mounting groove and the first switch.

10. A water purifier, characterized in that, Includes the filter element as described in any one of claims 1 to 9.

11. The water purifier according to claim 10, characterized in that, It also includes a connector, which has a fifth water flow channel and a sixth water flow channel spaced apart. The connector causes the valve assembly to have the first state and the second state by squeezing the first switch and unsqueezing the first switch.
