BG108560A - Vacuum cleaner water filter - Google Patents

Abstract

The filter can be used for direct building into, as well for building of new vacuum cleaner designs. It has simplified structure and it completely cleans the sucked in operating air from mechanical and dust particles and cleans any found mites, spores and smells. The cleaned air coming out of the vacuum cleaner does not contain even the finest dust particles. The filter includes centrifugal compressor (3) mounted under a cover (1) in the vacuum cleaner. Coaxially, under compressor (3), to the inner housing (12) a cyclone (16) is fitted for final air cleaning. Mixer (22) enters housing (14) in the area of its bottom. In the interior of mixer (22) there is an outlet opening (20), and around its surrounding wall there is a wedge-like opening (20) for agitating and mixing the fine dust particles. In the surrounding wall of cyclone (16) there is tangential inlet (14') which is found on the side of opening (18) of mixer (22). Inlet (14') has the same orienting to opening (18) of mixer (22).In the lower part of housing (12) there is an opening (5), and directly in it a sprayer (4) is fixed. In the lower end, along the surrounding walls of sprayer (4) a conical element (8) is externally made for subsequent spraying of water drops and bubbles. A grating-sensor (7) is mounted on the upper base of sprayer (4) on its inner side. A carpet beater can also be attached to the corrugated vacuum cleaner hose comprising external part (23), inner mobile part (31), brush (32) and electromagnets made of metal part (26) and electric windings (29). To part (31), springs (33) are fixed. The pulsing supply of the electric windings (29) is made by means of a diode (30).
