Cleaning and sterilizing apparatus combined with an ultra-violet lamp

Abstract

A cleaning or sterilizing apparatus combined with UV lamp consisting of an upright compact vacuum cleaner (26) comprising a dust container (27) with a transparent bottom (28) and a suction nozzle (34) incorporated in the bottom (28) and a protective housing (31) which covers the dust container (27) and which incorporates a fan (53) with a centrifugal dust filter (54) and UV germicidal lamp fixture (14) for destroying micro-organisms on cleaning surface and inside the dust container (27). The dust filter (54), which consists of a cylindrical grating (62) with or without a cylindrical paper filter (63), is mounted to the cylindrical opening (59) of the fan's impeller (53a) and located partly outside of the fan's casing (60) but inside the dust container (27). Rotating at high speed, the fan's impeller (53a) sucks in the air through the dust filter (54), which throws of dust particles outward toward the space inside the dust container (27) preventing clogging, separating particles from the air and obtaining purification of the air.

Description

technical field [0001] The present invention relates to conventional vacuum cleaners or electrically or mechanically driven brooms (sweepers) incorporating ultraviolet lamps, and in particular to those having a germicidal effect capable of killing bacteria, viruses and other primitive organisms or destroying their infectivity during cleaning UV germicidal lamps and UV black light lamps that enhance the visibility of white, glowing, fluorescent ions and substances during vacuum cleaning. Background technique [0002] According to the prior art, there are two types of ultraviolet lamps, UV lamps with germicidal effect or UV germicidal lamps and UV lamps with black light effect or UV black light lamps, which are related to the invention disclosed in this application. The UV germicidal lamp is a low-pressure mercury vapor discharge lamp with a tubular glass package, which emits short-wave ultraviolet rays with a peak value of 253.7nm (UV-C) for killing bacteria, viruses and othe...

AI Technical Summary

Problems solved by technology

Because the structure of any UV germicidal lamp cannot be constructed of any fluorescent material, the UV lamps disclosed in this patent cannot provide a black light effect that makes fluorescent particles and substances glow or become visible and makes white visible particles and substances more readily visible. See, therefore the light cannot be used to increase the visibility of said particles on the cleaning surface during cleaning

[0014] According to the prior art, UV black light lamps with black light effects cannot be used in combination with vacuum cleaners or electric or mechanically driven brooms (with or without UV germicidal lamps) to make white visible particles and substances more visible and to make Fluorescent particles and substances glow and are more easily seen even though they are invisible under normal light and therefore cannot be used to enhance the visibility and visual detection of said particles and substances during cleaning
