The traditional disinfection technology adopts chloride, alcohol or ozone, and the disinfectant is a highly toxic, flammable and explosive substance. The use of these substances poses a potential threat to field operators as well as to the surrounding environment and to residential safety. The ultraviolet disinfection device has the characteristics of high intelligence, safe and reliable operation, simple maintenance, low cost and the like. The single chip microcomputer of the controller collects information of the human body induction sensor, the acceleration sensor and the image sensor to be analyzed and judged, once the elevator car is in an unmanned state, the UVC ultraviolet lamp or the light shield is started to be opened for disinfection, and once the elevator car is analyzed and judged that a person enters, the UVC lamp or the light shield is closed to stop disinfection, and only by selecting proper power of the UVC ultraviolet lamp, viruses can be killed within a few minutes, so that safe, convenient and quick disinfection is realized.

The degassing unit of this application embodiment only needs 5 to 10 minutes accumulatively, can be in order to kill about 99% virus in the elevator, and this patent can open ultraviolet lamp or lens hood automatically and disinfect under the unmanned state of elevator, goes into to go out the lamp until someone. Therefore, the actual virus killing time of the general elevator, particularly the residential elevator, every day is longer than the riding time of the elevator. Therefore, the full-automatic all-weather uninterrupted ultraviolet disinfection lamp has high intelligentization, can replace artificial disinfection and automatically control disinfection. High safety and high disinfection efficiency.

Finally, the contactless key interface of the embodiment of the application also has a wireless local area network monitoring function and an alarm device, so that a user can timely turn off the ultraviolet lamp in an emergency state, and harm caused by the wrong operation of the device is prevented.
