Sterilizing device, sterilizing button and elevator

Technical Field

The utility model relates to a disinfection field, more specifically say, relate to a degassing unit, disinfection button and elevator.

Background

Ultraviolet radiation is a mode widely applied to virus elimination at present, and the traditional ultraviolet light source is a low-pressure mercury lamp, the main wavelength of which is 185nm and 254nm, the traditional ultraviolet light source has the defects of high working voltage, large volume, difficulty in frequent switching and the like, and the traditional ultraviolet light source cannot be applied to the interior of a key. Light Emitting Diodes (LEDs) have the advantages of small size, low power consumption, low cost, low operating voltage, and capability of being frequently switched at high speed. In recent years, LED chip technology has been developed to realize mass production of LED chips in the deep ultraviolet band (less than 300nm), especially in the wavelength range of 260nm to 285nm, and the ultraviolet light of this wavelength is easily absorbed by DNA and RNA, and can destroy the DNA and RNA structures of microorganisms such as viruses and bacteria, and cause them to break, crosslink or form photochemical products, so that they cannot proliferate, replicate or directly die.

The elevator is used as an important tool for urban vertical traffic, and due to frequent contact of people, the elevator buttons and other positions have higher risks of cross infection of viruses and pathogenic bacteria. Generally speaking, people mainly spray and wipe the mode of disinfectant to elevator button disinfection mode, comparatively waste time and energy, and the antiseptic solution is gone deep into elevator button inside damage circuit easily.

Although some elevators adopt non-touch elevator control modes, such as face recognition for selecting floors, mobile phone control for elevators and the like, the modes are difficult to be suitable for public places and meet the use habits of people of different ages. The button is still the mainstream scheme of the current elevator control, so that the real-time rapid disinfection of the surface of the elevator button is an urgent need for guaranteeing public safety.

In the existing elevator button application with disinfection function, the disinfection mode mainly adopted mainly comprises the steps that a single disinfection device is arranged on the surface of a button, or the disinfection device is arranged below a button panel, and the button is conveyed or rotated to the panel through a crawler belt to be disinfected.

Chinese patent application for disinfected elevator passenger interface, application No. CN200480044025.6, published 2009, 7.29, discloses a passenger interface device comprising at least one passenger interface device having an input member adapted to be touched by a human. A disinfectant is present on the contact surface, the disinfectant comprising a material activated by radiation. The radiation source irradiates a disinfectant to disinfect the passenger interface device. In one example, titanium dioxide is used as a photocatalyst for disinfecting the contact surface in response to ultraviolet radiation, and the invention activates the disinfectant by light irradiation for disinfection, and has a complicated structure, a short life of the disinfectant on the contact surface, and low practicality when the disinfectant is not easily added with light.
