The installation of the mounting plate 7 can be limited by the limiting component. After the limiting component no longer limits the mounting plate 7, the mounting plate 7 can drive the coarse filter 18, the fine filter 19 and the activated carbon layer 20 to move up and out of the inner cavity of the filter box 3, which is convenient for subsequent cleaning.
