Referring to fig. 1 and 2, the present invention provides a water purifier, which includes a housing 10, a waterway unit 20, a pump unit 30, a bracket 40 and a filter element 50, all of which are fixed in the housing 10. The bracket 40 is connected to the inner wall of the housing 10. The waterway unit 20 is located between the inner wall of the housing 10 and the bracket 40, and is communicated with the filter element 50. The waterway unit 20 is connected to the outside of the housing 10. The filter element 50 is fixedly arranged at one side of the bracket 40, and the water pump unit 20 is fixedly arranged at the other side of the bracket 40. The water pump unit 20 is connected to the waterway unit 20. An external water source flows into the filter element 50 from the outside of the housing 10 through the waterway unit 20, and filtered water reenters the waterway unit 20 and flows out of the housing 10, thereby completing filtration. The water pump unit 20 pressurizes the water flowing in the waterway unit 20 to directionally accelerate the flow.

Referring to fig. 3 and 4, the filter element 50 is inserted into the water purifier in a certain linear direction as an installation direction a. The cartridge 50 includes a body 51, a cartridge cover 52, a locking assembly 53, and a filter material 54. In this embodiment, the main body 51 is a hollow cylinder, and an opening is provided at one axial end thereof. The filter element cover 52 is closed to the opening of the body 51 to form a sealed space (not labeled), and the filter element 54 is sealed in the sealed space. The locking member 53 is connected to the cartridge cover 52, and the locking member 53 is extended and contracted in a direction not parallel to the mounting direction a. A groove (not shown) corresponding to the locking member 53 is formed on the inner wall of the housing 10 or the bracket 40. The outer side surface of the side of the filter element cover 52 facing away from the main body 51 is parallel to the radial direction of the main body 51, the locking assembly 53 is arranged on the outer side surface of the filter element cover 52 and can be extended and retracted along the radial direction of the main body 51 so as to be inserted into the inner wall of the shell 10 or the groove of the bracket 40 and fixed with the inner wall or the groove, and the filter element 50 can be prevented from moving along the installation direction A by the locking assembly 53, so that the positioning of the filter element 50 in the shell 10 is realized.
