When the frame needs to be installed, the frame is reset, the frame drives the support frame to move, the support frame drives the limit block and the clamping block to reset, the limit rod passes through the limit hole into the inner cavity of the limit block, the clamping rod enters the inner cavity of the clamping block, and then the limit block is fixed by the fixing mechanism to complete the installation, which solves the problem that most of the existing water purifier installation methods use screws and screws to cooperate with the mounting plate, and when the filter cartridge of the water purifier needs to be disassembled, cleaned or assembled, it is also necessary to use matching tools.

[0004] However, the new water purification device provided in the above technical solution still has many disadvantages in actual use. For example, when in use, it is necessary to manually clean out the wastewater in each filter and clean the filter element in the filter regularly, which makes cleaning more troublesome.
