11. As an optional solution of the detachable filter element assembly, the first end cover body has a circular structure, the groove structure is arranged coaxially with the first end cover body, and the groove of the groove structure The area of the mouth is larger than the area of the bottom of the groove.

12. As an optional solution of the detachable filter element assembly, the groove bottom of the groove structure is a closed cover, and the end surface of the closed cover away from the first end cover body is provided with a reinforcing rib.

13. As an alternative to the detachable filter element assembly, the reinforcing ribs include first reinforcing ribs, the first reinforcing ribs are ring-shaped and coaxial with the groove structure, and/or

14. The reinforcing ribs include second reinforcing ribs, and a plurality of the second reinforcing ribs are provided, and the plurality of second reinforcing ribs extend radially outward along the radial direction of the closure cover.

15. As an optional solution of the detachable filter element assembly, the outer edge of the first end cap body is provided with a skirt structure, and the skirt structure is oriented toward the first end cap body along the axis of the first end cap body. Extend in the direction of the two end caps.

16. As an alternative to the detachable filter element assembly, the first end cover body is provided with at least one third reinforcement

Rib, the third reinforcing rib is ring-shaped and coaxial with the groove structure.

17. As an optional solution of the detachable filter element assembly, the first end cover body, the groove structure and the clip are integrally formed.

18. Another purpose of the present utility model is to provide a filter with compact internal structure and convenient assembly and disassembly, which is beneficial to the further optimization of the layout of the entire vehicle mechanism.

19. In order to achieve the above objectives, the following technical solutions are provided:

20. As an alternative to the filter, it includes a threaded main housing and an upper housing, and also includes any one of the technical solutions of a detachable filter element assembly as mentioned above. The clip can be connected to the upper housing. The shell is snapped together.

21. As an alternative to the filter, the upper housing is provided with an inverted structure, the clamping member extends along the axial direction of the groove structure and is provided with a plurality of circumferential intervals, and a plurality of The clamping member can be clamped to the inner wall surface and/or the outer wall surface of the inverted buckle structure.

22. As an alternative to the filter, a plurality of the clamping members are clamped on the inner wall surface of the inverted buckle structure, and the inner wall surface is provided with a first protrusion protruding circumferentially, and the clamping member A second protrusion is protrudingly provided along a direction away from the axis of the groove structure, and the first protrusion and the second protrusion are provided correspondingly.

23. Compared with the prior art, the detachable filter element assembly provided by the present utility model has the following beneficial effects:

24. The first end cover body is recessed in the direction of the filter element to form a groove structure, and the bottom of the groove structure is provided with a clamping piece on the end face away from the filter element, so that the detachable filter element assembly and the filter When the filter housing is opened to replace the detachable filter element assembly, the detachable filter element assembly and the housing are snapped together as a whole. When the housing is lifted, the detachable filter element assembly can be removed from the filter Take it out of the cleaner to avoid staining your hands and no need for secondary operations, which improves the replacement efficiency; the groove structure is recessed toward the filter element to avoid additional clamping pieces that will increase the installation space and realize the internal structure of the detachable filter element assembly More compact, reducing the space occupied.

25. Compared with the prior art, the beneficial effects of the filter provided by the present utility model are:

26. The first end cover body is additionally provided with a clamping piece and is recessed in the direction of the filter element to realize the clamping between the first end cover and the upper shell, which is convenient for assembly and disassembly, and has a compact internal structure, which is beneficial to the further optimization of the layout of the whole vehicle. .
