Description

UVC LED elevator button sterilizer

Technical Field

The utility model relates to an ultraviolet sterilization disinfection field especially relates to a UVC LED elevator button sterilizer is applied to the elevator button and disinfects.

Background

Relevant studies have shown that new coronavirus can survive for hours on the surface of smooth objects such as elevator buttons. Under the large environment of epidemic situation normality, if the elevator button is disinfected in time, viruses on the fingers of a patient can be remained on the button and transmitted to other people, and the probability of virus cross infection can be greatly increased. UVC LED is a novel environmental protection deep ultraviolet light source, is the ideal choice that the elevator button disinfected. However, the current UVC LED elevator button sterilization scheme has drawbacks in cost, versatility, and ease of operation.

The existing scheme has two main ways of ultraviolet irradiation sterilization:

(1) direct irradiation: namely, the ultraviolet light source is opposite to the elevator button, and the front side irradiates. However, the button cannot be fully closed, so that the UVC LED is required to be installed on the lamp shade, and the lamp shade can be opened and closed like book page turning, so that the button can be guaranteed to be unaffected in use. The turnover mechanism of the lampshade is easy to damage, and the lampshade must be manually turned over before the button is used each time, which is a disadvantage that the scheme is difficult to avoid.

Please refer to CN 202020246851-a sterilizing and disinfecting device for elevator buttons, the UVC LED of the patent is mounted on a lamp cover, and sterilizes the elevator buttons in a turning manner.

And when the elevator buttons are more and the arrangement is more intensive, the internal structure of the sterilizing device becomes very complicated, and the assembly cost of the device is greatly increased. Meanwhile, more than 3 UVC LEDs are required to be used in each hole for uniform irradiation, and the cost of the device is further increased.

Please refer to CN 202022517995-an elevator button sterilization device: this patent is placed UVC LED in the sterilizing equipment of trompil in, and the accuracy is disinfected to the button position.
