At the same time, people can also replace the bottom cover 2 according to needs during assembly, and are not limited to one type of shell.

[0026] A further optimization scheme is provided. In order to facilitate the connection between the bottom cover 2 and the shell of the water purifier, ears 25 are provided on both sides of the bottom cover 2. Specifically, a groove matching the ear 25 is provided inside the shell of the water purifier to fix the ear 25, wherein the ear 25 includes a transverse section 26 and a vertical section 27, one end of the transverse section 26 is connected to one end of the vertical section 27, the ear 25 is used to be clamped on the shell of the water purifier, and the side of the vertical section 27 away from the transverse section 26 is set as a plane for fixing with the caliper, wherein the number of ears 25 is provided with at least two, so as to facilitate keeping the shell balanced.

[0027] According to a further optimized solution, in order to ensure the stability of the latch 25 , an annular step surface is provided on the outer peripheral surface of the bottom cover 2 , and the other end of the vertical section 27 is connected to the step surface.

[0028] To further optimize the solution, in order to ensure the tightness of the connection between the top cover 1 and the annular cylinder 3, a first sealing ring 9 is provided between the top cover 1 and the annular cylinder 3.

[0029] A further optimized solution is to facilitate the connection between the top cover 1 and the annular cylinder 3.

The first filter body 4 is wrapped around the outside of the double-layer annular sleeve 8, that is, the water enters the outer shell through the first water inlet 21, is filtered by the first filter body 4, and is discharged from the first water outlet, and then enters the second filter body 5 through the second water inlet 23 and the outer layer of the double-layer annular sleeve 8. After the water is filtered, it is finally discharged outward through the inner layer of the double-layer annular sleeve 8 and the second water outlet 24, thereby achieving water purification.

[0033] To further optimize the solution, the first filter body 4 includes a carbon fiber filter element and a polypropylene filter element arranged from the inside to the outside. The carbon fiber filter element is a composite depth filtration composed of cellulose and activated carbon powder, combined with a dual-function filter element material structure of activated carbon adsorption. The outer layer of the center column of the filter element is lined with a precision fiber filter material, and is surrounded by activated carbon fiber cloth. When the liquid flows through the filter material, the outer layer of the deep fiber filter material structure can block the polluting particles, and the activated carbon in the filter cloth can remove odor, odor, sediment, pigment, volatile organic compounds (VOC) and organic chemicals in the filtrate; the polypropylene filter element is a polypropylene particle that is melted and sprayed into fine fibers and tightly wound into a white tubular filter element. It is non-toxic, the fibers will not fall off during filtration, and it maintains good air permeability.

[0034] To further optimize the solution, a carbon rod filter element is set in the second filter body 5.
