Vacuum cleaner filter assembly

摘要

A filter assembly for utility type vertical axis vacuum cleaner comprising three separate members- a substantially cup-like fabric filter including a resilient upper peripheral edge, a rigid hoop about which the upper edge of the filter is fitted, a polyvinylchloride seal fitted about the upper rim of the hoop. Also disclosed is a wet/dry utility vacuum cleaner having an open top dirt receptacle and a power suction module including a housing supporting a motor-blower unit in the receptacle and having a liquid sensing air shut-off device depending from the housing. An embodiment of the filter assembly is mounted in the receptacle with the seal interposed between mating peripheral edges of the receptacle and the housing, and includes a hole in the bottom of the filter through which the sensing element protrudes.
