[0044] The working principle of this utility model:

[0045] When the filter element needs to be installed, the filter element 2 is inserted into the filter element cavity 11 of the middle frame body 1, and the filter element 2 is pushed inward. When the push rod matching portion 6 on the filter element 2 contacts the push rod 5, the movement stops. At this time, the door cover 4 is turned upward, and the door cover 4 pushes the filter element 2 to move into the filter element cavity 11 until the male buckle 72 contacts the female buckle 31, and the male buckle 72 moves inward and locks with the female buckle 31. The door cover 4 reaches the locked state, and the filter element 2 is installed. At this time, the filter element 2 is connected to the waterway, and the water purifier can work normally;

[0046] When the filter element needs to be removed, press the male buckle 72, and the male buckle 72 will be separated from the female buckle 31. At this time, turn the door cover 4 downward, the push rod matching part 6 on the filter element 2 contacts the push rod 5, and continuously pull the filter element 2 outward until the filter element 2 is separated from the water channel. When the filter element 2 reaches the predetermined position, the filter element is taken out by pulling the handle 24, thereby achieving the effect of removing the filter element.
