The snap-on member 220 may be disposed at any suitable location within the housing 400. In the embodiment shown in the figures, the swivel snap member 220 may be connected to the filter base 200. The bayonet member 220 is rotatable about the axis of the filter cartridge 100. That is, as shown in fig. 3, the bayonet elements 220 are rotatable about the axis of the filter cartridge 100 in the circumferential direction a-B. The direction A is a first circumferential direction, the direction B is a second circumferential direction, and the first circumferential direction A and the second circumferential direction B are opposite. The rotation member 220 has a locked position where it engages with the filter cartridge 100 and an unlocked position where it disengages from the filter cartridge 100 during rotation.

One end of the unlocking assembly 300 may be connected to the swivel snap member 220. The other end of the unlocking assembly 300 may extend out of the water purifier through a slot in the housing 400 of the water purifier. The unlocking assembly 300 is movable along the circumferential direction a-B of the filter cartridge 100 between an initial position and a dialing position. With the unlocking assembly 300 in the initial position, the rotation-blocking member 220 may be in the locked position.

In the process, the unlocking assembly 300 may rotate the rotation member 220 from the locked position to the unlocked position in the first circumferential direction a. When the rotation-locking member 220 is in the unlocked position, the second locking portion 240 and the first locking portion 110 may be offset in the circumferential direction a-B of the filter cartridge 100. At this time, the filter cartridge 100 may be moved toward the housing 400 in the first axial direction M and be inserted into the housing 400. After the unlocking assembly 300 is released, the restoring member 230 can release the elastic potential energy, so that the rotation-locking member 220 rotates from the unlocking position to the locking position along the second circumferential direction B, and the first locking portion 110 and the second locking portion 240 are engaged along the axial direction M-N of the filter element, thereby locking the filter element 100 to the housing 400. At the same time, the snap-on member 220 may allow the unlocking assembly 300 to return to the initial position from the toggle position.

When the filter cartridge 100 is removed, the unlocking assembly 300 is moved from the initial position to the dialing position by dialing. In the process, the unlocking assembly 300 may rotate the rotation member 220 from the locking position to the unlocking position along the first circumferential direction a, and when the rotation member 220 is in the unlocking position, the second locking portion 240 and the first locking portion 110 may be staggered along the circumferential direction a-B of the filter cartridge 100. At this time, the filter cartridge 100 may be withdrawn in the second axial direction N, thereby completing the detachment of the filter cartridge 100 from the housing 400. Thereafter, the unlocking assembly 300 is released, and the restoring member 230 can release the elastic potential energy to rotate the rotation-locking member 220 from the unlocking position to the locking position along the second circumferential direction B. At the same time, the snap-on member 220 may allow the unlocking assembly 300 to return to the initial position from the toggle position. And then the filter element 100 is taken out from the mounting hole 401.

Adopt the utility model provides a water purifier, filter core 100 are along the in-process that first axial direction M removed to casing 400, through stirring unblock subassembly 300 or disect insertion filter core 100, just can accomplish locking and unblock between them. In the unlocking process, only the unlocking assembly 300 needs to be directly shifted, and after the rotating and clamping member 220 rotates to the unlocking position, the filter element is reversely pulled out. Therefore, the water purifier simplifies the number of parts involved in the unlocking process of the filter element 100 and the shell 400, so that the structure of the water purifier is simplified, the number of links for mutual matching of the parts is reduced, the requirement on the processing precision is reduced, the manufacturing cost is reduced, and the high yield is ensured.

Preferably, as shown in fig. 4A to 4E, the shapes of the first locking part 110 and the second locking part 240 may be designed. Specifically, the first locking portion 110 may have a first push top surface 111 and a first locking surface 112. The first push top surface 111 may be located below the first locking surface 112. The second locking part 240 may have a second push top surface 241 and a second locking surface 242. The second push top surface 241 may be located above the second locking surface 242. The first and second push top surfaces 111 and 241 may be inclined upward in a direction from the locking position to the unlocking position (i.e., the first circumferential direction a). The first and second locking surfaces 112, 242 may extend in the circumferential direction a-B. Preferably, the first and second locking parts 110 and 240 may be wedge-shaped protrusions.

During installation of the filter cartridge 100, the filter cartridge 100 is inserted in the first axial direction M, and when the first locking portion 110 abuts against the second locking portion 240, the first push top surface 111 and the second push top surface 241 may contact each other, as shown in fig. 4A. The first locking portion 110 continues to move in the first axial direction M, urging the second locking portion 240 to rotate in the first circumferential direction a, as shown in fig. 4B. The first locking portion 110 continues to move in the first axial direction M until the first locking portion 110 is misaligned with the second locking portion 240 in the circumferential direction a-B, as shown in fig. 4C. The first locking portion 110 continues to move in the first axial direction M, at which point the first locking portion 110 no longer applies a force to the second locking portion 240, and the second locking portion 240 stops rotating in the first circumferential direction a, as shown in fig. 4D. The first locking portion 110 continues to move in the first axial direction M, the first locking portion 110 passes over the second locking portion 240, and at this time, under the action of the reset piece 230, the second locking portion 240 rotates in the second circumferential direction B, so that the first locking surface 112 can abut against the second locking surface 242, thereby completing the locking of the filter cartridge 100 to the housing 400, as shown in fig. 4E.
