Filter set device with replaceable three-dimensional filter paper for French press kettle

Abstract

The invention relates to a French press kettle, in particular to a filter set device with replaceable three-dimensional filter paper for the French press kettle. The device comprises a pressing rod, ametal bracket and the replaceable three-dimensional filter paper; the metal bracket is fixedly connected with the pressing rod, the replaceable three-dimensional filter paper wraps the metal bracketand can be in interference fit with the inner wall of the French press kettle body, and the friction force generated by interference fit of the replaceable three-dimensional filter paper and the innerwall of the French press kettle body is larger than or equal to the sealing force required for preventing leakage of filtered residues and smaller than the pressure from the pressing rod and the metal bracket during normal use. According to the filter set device, the replaceable three-dimensional filter paper is adopted for replacing French press kettle metal filter nets in the prior art, so thata better filtering effect is achieved; disposable convenience after use is provided, the user experience is also improved, and the convenience and the health security are greatly improved.
