Referring to fig. 1-8, one embodiment of a cartridge assembly of the present invention is shown. The filter cartridge device includes a mounting frame 100, a filter cartridge assembly 200, and a filter cartridge locking mechanism 300. The mounting frame 100 has a receiving cavity into which the filter element assembly 200 is inserted. The filter cartridge assembly 200 includes a filter cartridge 210, a handle 220 pivotally attached to an end of the filter cartridge 210. As shown in fig. 6 and 7, the handle 220 is pivotable between a snap-fit position and a lift-up position, and is connected to the filter flask 210 by a pin. In this embodiment, the lifting position of the handle 220 is perpendicular to the end surface of the filter flask 210. The outer circumferential surface of the filter flask 210 is provided with a locking part 211, which is mainly used for fixing the filter flask 210 and preventing the filter flask 210 from separating under the action of water pressure.

When the handle 220 is located at the buckling position, the locking part and the sliding tongue 320 are locked to limit the outward axial movement of the filter bottle 210, so that the filter bottle 210 and the mounting frame 100 are in a locking state; when the handle 220 is pivoted to the lifted position, the handle 220 pushes the pressure lever 310 to move axially, the sliding tongue 320 is driven to rotate along the circumferential direction of the outer circumferential surface of the filter flask 210 through the first inclined surface structure, the locking between the locking part and the sliding tongue 320 is released, the outward axial movement of the filter flask 210 is released, and the filter flask 210 and the mounting frame 100 are in an unlocked state. In the filter element locking mechanism 300, the driving structure between the pressing rod 310 and the sliding tongue 320 adopts an inclined plane structure, so that the stability, reliability and motion continuity of the driving process can be ensured, and the size of the filter element locking mechanism 300 can be reduced, thereby the filter element locking mechanism 300 is simple and effective, and the purpose of convenience is achieved.
Specifically, the locking portion is a locking boss 211 provided on an outer side wall of the filter flask 210. The sliding tongue 320 is arranged on one side of the locking boss 211 close to the handle 220, and an unlocking groove 323 is arranged on one side of the sliding tongue 320 close to the filter bottle 210. As shown in fig. 3 and 6, when the handle 220 is located at the engaging position, the locking boss 211 abuts against the sliding tongue 320 and is disposed in a staggered manner with the unlocking groove 323 to limit the outward axial movement of the filter flask 210; as shown in FIG. 7, when handle 220 is pivoted to the lifted position, lever 310 drives tongue 320 to rotate circumferentially, causing unlocking slot 323 to oppose locking boss 211, thereby releasing filter flask 210 from outward axial movement.
Specifically, referring to fig. 2 and 5, the first inclined surface structure includes a first inclined rib 322 disposed on the sliding tongue 320, and a second inclined rib 312 disposed on the second end of the pressing rod 310; the first inclined rib 322 and the second inclined rib 312 are engaged. The second end of the pressing rod 310 is cut off to form a step part 311 on the side close to the sliding tongue 320, and the second inclined convex rib 312 is arranged on the step part 311. In this embodiment, two unlocking slots 323 are provided, and are respectively provided on two sides of the sliding tongue 320, and two locking bosses 211 are correspondingly provided, so as to enhance the locking firmness between the sliding tongue 320 and the locking bosses 211. The middle part of the sliding tongue 320 is provided with a concave groove 321, the first inclined convex rib 322 is arranged in the concave groove 321, and the arrangement of the concave groove 321 can enable the pressure rod 310 to be arranged close to the filter flask 210, so that the whole volume of the filter element device is reduced.
In order to facilitate the installation of the filter element assembly 200, a second inclined plane structure is arranged between the locking boss 211 and the inner wall of the unlocking groove 323, when the filter bottle 210 is inserted into the accommodating cavity, the locking boss 211 enables the sliding tongue 320 to rotate circumferentially through the second inclined plane structure, so that the locking boss 211 slides into the unlocking groove 323; when the locking boss 211 passes through the unlocking groove 323, the sliding tongue 320 is reset and abuts against the locking boss 211, so that the filter bottle 210 is locked in place. In the present embodiment, as shown in fig. 6, the second slope structure includes a slope a disposed at a side surface of the locking boss 211.
As shown in fig. 2 and 7, in the present embodiment, the handle 220 has a protruding portion 221 at both ends pivotally connected to the filter flask 210, and when the handle 220 is lifted, the protruding portion 221 presses the pressing rod 310 to move axially inward.

In the installation process, referring to fig. 8, when the handle 220 is located at the lifted position, the filter bottle 210 is inserted into the receiving cavity, the third inclined surface structure of the protruding portion 221 abuts against one side of the movable cushion block 350 close to the filter bottle 210, the movable cushion block 350 is pushed by the third inclined surface structure to move in the direction away from the filter bottle 210 along the radial direction of the filter bottle 210 until the protruding portion 221 of the handle 220 contacts with the first end face of the pressing rod 310, and at this time, the sliding tongue 320 has rotated around the shaft by a certain angle under the action of the locking boss 211. Then, the filter bottle 210 is inserted further inward, and the extension 221 abuts against the first end surface of the pressing rod 310 and pushes the pressing rod 310 to move axially. In this embodiment, the first inclined ribs 322 and the second inclined ribs 312 are spaced apart from each other by a distance greater than or equal to the moving distance of the pressing rod 310, so that after the pressing rod 310 moves axially, the first inclined ribs 322 and the second inclined ribs 312 are not in contact with each other. When the locking boss 211 extends out of the unlocking groove 323 of the sliding tongue 320, the sliding tongue 320 is reset under the action of the spring and is locked with the locking boss 211, and the filter element is installed in place. At this time, the first inclined rib 322 of the sliding tongue 320 contacts with the second inclined rib 312 of the pressing rod 310, and when the handle 220 is rotated, the movable pad 350 and the pressing rod 310 are reset under the action of the spring until the handle 220 is rotated and reset to the fastening position. In the embodiment, the movable cushion block 350 is used for preventing the problem that the filter flask 210 is not locked in place during installation, the locking boss 211 and the handle 220 are not simultaneously used, and a stroke difference is formed by the movable cushion block 350 so as to ensure that the sliding tongue 320 and the locking boss 211 are locked and the pressure rod 310 does not interact with the sliding tongue 320.
