Description

TECHNICAL FIELD

[0001] The utility model relates to a filter element assembly and water purifier. BACKGROUND

[0002] The traditional filter element assembly is of screw type, and the filter element is fixed by rotating the bottom buckle and the lock catch structure on the waterway plate. When disassembling, the filter element is rotated counterclockwise and pulled out. The filter element assembly of screw type has the following disadvantages: firstly, the waterway plate is one of the main pressure points of the water purifier in use, and the rotating disc cooperating with the filter element in the waterway plate will be deformed under pressure. The traditional filter element replacement method needs to align the water inlet and outlet of the filter element with the waterway plate and then rotate, and after multiple rotations, the sealing ring between the rotating disc and the waterway plate will be dislocated, which will cause water leakage and seriously affect the user experience. Secondly, the existing replacement method is laborious and needs to be twisted, and cannot realize self-replacement of every user. Thirdly, for the user who uses the water purifier for the first time, the replacement structure is unfamiliar, and cannot realize self-replacement of every user. Finally, if the rotation is not in place after the filter element and the rotating disc in the waterway plate are well matched, it will also cause the phenomenon of reduced water quantity. SUMMARY

One end of the locking starting part 31 is connected to the elastic assembly 33, and the other end of the locking starting part 31 is exposed to the opening 11. When the locking starting part 31 is pressed downward, the locking starting part 31 drives the elastic buckle 32 to move downward to the first position, and the second end 325 of the elastic buckle 32 is clamped in the clamping groove 13. When the filter core 2 is pressed downward, the trigger part 21 drives the second end 325 of the elastic buckle 32 to move away from the clamping groove 13 and out of the clamping groove 13.

The inclined surface is arranged on the side of the filter core 2 away from the clamping groove 13, forming a structure of small at the bottom and large at the top. When the filter core 2 is pressed down, the inclined surface of the filter core 2 will push the buckle part 323, so that the second end 325 of the buckle part 323 moves away from the clamping groove 13, and the second end 325 of the buckle part 323 is out of the clamping groove 13. When the filter core 2 is released, under the action of the second elastic element 333, the filter core 2 and the shell 1 are unlocked.
