Description

Safety sterilizing cabinet

Technical Field

The invention relates to the field of disinfection cabinets, in particular to a safe disinfection cabinet capable of avoiding ultraviolet ray misillumination.

Background

At present, the household disinfection cabinet on the market generally adopts ultraviolet irradiation and ozone for disinfection and sterilization, wherein an ultraviolet lamp is generally installed on the inner wall of the disinfection cabinet irradiated by the ultraviolet ray, and articles are irradiated and disinfected by the ultraviolet ray emitted by the ultraviolet lamp. For example, chinese utility model patent No. ZL201420813968.1 (No. CN204337348U) discloses a disinfection cabinet, which comprises a cabinet body, wherein an ultraviolet lamp is arranged on the side wall of the cabinet body. This kind of sterilizer can only open the cabinet door under the stop work state, if open the cabinet door under operating condition, then the ultraviolet ray of ultraviolet lamp transmission under operating condition can shine on one's body the user to cause the potential safety hazard. In addition, in the conventional disinfection cabinet using the ultraviolet lamp, the ultraviolet lamp is generally fixed on the inner wall of the cabinet body, so that when placing and taking disinfection articles, the ultraviolet lamp may touch the lamp tube of the ultraviolet lamp, and the lamp tube is damaged by the collision.

In addition, among traditional sterilizer, under operating condition, ultraviolet lamp all is in quiescent condition with the article of taking the disinfection, and there is the shadow face ultraviolet ray to the irradiation of tableware to there is the dead angle of disinfecting, influences the disinfection effect then. Therefore, the ultraviolet lamp can irradiate the objects to be disinfected more comprehensively by rotating the ultraviolet lamp, for example, the Chinese patent invention with the patent number ZL200510092978.6 (the publication number is CN1919349A) discloses a disinfection cabinet which comprises a shell, a box body arranged in the shell, a door body, a partition frame arranged in the box body and a control circuit, wherein a rotatable lamp holder for arranging an ultraviolet lamp tube is arranged at the top of the box body. This patent has solved the problem at disinfection dead angle through the ultraviolet lamp rotation, but solves the problem at ultraviolet irradiation dead angle through the ultraviolet lamp rotation and can arouse the following condition: the ultraviolet lamp easily causes the winding of the wires on the connecting lamp tubes in the rotating process, thereby influencing the stability of the working performance of the disinfection cabinet. Therefore, the disinfection cabinet provided with the rotatable ultraviolet lamp has higher design requirements on the internal structure and higher design difficulty.
