Description

UVC-LED sterilizer

Technical Field

The utility model belongs to the electrical apparatus field, in particular to UVC-LED sterilizer.

Background

The disinfection cabinet is a tool for sterilizing and drying tableware, clothes, medical instruments and other articles in an ultraviolet ray, high temperature, ozone and other modes. Among them, the ultraviolet disinfection cabinet is concerned about because of its advantages of fast start, no delay and low power consumption. At present, UVC-LED disinfection cabinets are common. UVC is also called short wave sterilization ultraviolet, has the wavelength range of 200-275 nm, has the weakest penetrating power, cannot penetrate most of transparent glass and plastics, and is widely applied to various application fields.

The existing UVC-LED disinfection cabinet generally arranges UVC-LED lamps on the upper and lower inner walls, but the design has certain disadvantages. Because the common UVC-LED lamps are not waterproof, and the objects to be disinfected are mostly wet, the UVC-LED lamps on the lower inner wall are easily soaked in water, so that the reliability of the disinfection cabinet is reduced; if the lower inner wall adopts the UVC-LED lamp that possesses waterproof function, this can directly increase the design degree of difficulty to increase the cost. Particularly, when the sterilizing cabinet sterilizes and dries the dishes, especially for small-inner-diameter and high-height dishes such as baby bottles, if the UVC-LED lamps are disposed on the upper and lower inner walls of the sterilizing cabinet, the dishes need to be vertically placed. Under the condition, when the tableware is placed with the opening facing upwards, water can be gathered at the bottom of the bottle, and the effect of sterilizing and drying is poor; when the opening is placed downwards, the UVC-LED lamp on the lower inner wall of the disinfection cabinet is easily soaked by water.

In view of this, how to design a UVC-LED disinfection cabinet is a subject of the present invention to solve the above problems.
