Between be circumferentially with sealing element.
Preferably, the upper cover body by integral forming, first connecting portion and filter material filling cavity clamping.
Preferably, the filter flask ontology is equipped with first annular boss close to bottom, and filter material filling cavity corresponding position is equipped with
Second annular convex platform of adaptation, first annular boss and the second annular convex platform abut.
Preferably, the upper outlet body water outlet is bolted with connector, is bolted with knob on the connector.
Preferably, the lower cover bottom is equipped with sewage draining exit, and the sewage draining exit is equipped with blowdown valve.
The beneficial effects of the utility model are: filling filter material in filter material filled cavity body when utility model works, water passes through
Water inlet enters water inlet flow channel, proceeds to filter material by lower cover and fills inside cavity, water is after filtering or adsorbing contaminant by upper
Lid outflow；A confined space is formed after upper and lower cover body and filter material the filling cavity cooperation of the utility model, is placed among it
Filtering material；Upper and lower cover body designs for porous type, and the aperture in hole is less than the minimum grain size of filtering material, guarantees filtering material not
Outflow.The structure design of the utility model is reasonable, and installation, disassembly or replacement are easy, easy to use.
