Domestic portable ultraviolet sterilizing lamp

Abstract

The invention discloses a domestic portable ultraviolet sterilizing lamp, which comprises a shell, wherein four universal wheels are arranged at the bottom of the shell; a cavity is kept in the shell;a protective door is arranged in an opening of the cavity; by virtue of the protective door, the cavity can be opened or closed; a base is arranged in the cavity; a supporting rod is arranged on thebase; an ultraviolet sterilizing lamp body is arranged on the supporting rod; the base and the supporting rod are connected via a fixed shaft; the supporting rod can rotate around the fixed shaft; a push handle is arranged at the upper end of the supporting rod; a tightening knob is arranged on the fixed shaft, so that the supporting rod can be located; the supporting rod and the ultraviolet sterilizing lamp body are connected by virtue of a cage-type universal joint; a control cabinet is arranged in the cavity; and a timer, a circuit control board and a switch are arranged in the control cabinet. The sterilizing lamp provided by the invention is small in occupied space and convenient to use, and sterilizing time can be set; in addition, the ultraviolet sterilizing lamp, which adopts a storage battery, can continue working in the case of power failure.

Description

technical field [0001] The invention relates to a sterilizing device, in particular to a household portable ultraviolet sterilizing lamp. Background technique [0002] The ultraviolet germicidal lamp is actually a low-pressure mercury lamp. The low-pressure mercury lamp emits ultraviolet light by being intensified by the lower mercury vapor pressure (<10-2Pa). There are two main emission lines: one is 253.7nm wavelength; the other is 185nm wavelength, both of which are visible to the naked eye. Invisible ultraviolet light. [0003] The only artificial amalgam (alloy) lamp sources capable of outputting sufficient UVC intensity for engineered disinfection. The lamp tube of the ultraviolet germicidal lamp is made of quartz glass. The mercury lamp is divided into three types according to the difference in the mercury vapor pressure in the lamp tube after lighting and the difference in the output intensity of ultraviolet light: low-pressure low-intensity mercury lamp, medium...

AI Technical Summary

Problems solved by technology

[0004] The vehicle-mounted ultraviolet germicidal lamp of the prior art takes up a large space, is inconvenient to move, and is extremely inconvenient to use at home, and because the center of gravity of the vehicle-mounted ultraviolet germicidal lamp of the prior art is relatively high, the stability is poor, and there is a problem Larger safety hazard, not suitable for home use

Moreover, the ultraviolet germicidal lamps in the prior art are generally directly powered by 220 volts of alternating current, and cannot be used during a power outage or power outage, and are not suitable for home use.
