Elevator button separating membrane automatic winding, unwinding and sterilizing device

Abstract

The invention discloses an elevator button separating membrane automatic winding, unwinding and sterilizing device. The device comprises a human hand presence / absence photoelectric sensor, a disinfectant sprinkler head and a disinfectant feed pump which are mounted on a mounting bottom plate, a guide roller, a friction guide roller and a drive axle which are wound on the unwinding side of an unwinding position separating membrane drum, a guide roller wound on the winding side of the unwinding position separating membrane drum, and a transparent separating membrane arranged on the unwinding position separating membrane drum. The device is mounted in front of elevator buttons, and the transparent separating membrane in the device covers the front portions of the elevator buttons; a person only needs to make contact with the transparent separating membrane by hand so as to operate the elevator buttons, and accordingly, the hidden danger that the person is infected with infectious diseasesthrough the elevator buttons is avoided; each time the elevator buttons are operated, the device automatically winds up the used segment of the transparent separating membrane and replaces the used segment with an unused segment of the transparent separating membrane, and therefore, the hidden danger of infecting with infectious diseases through the transparent separating membrane is also avoided; and furthermore, the device can sterilize the used segment of the transparent separating membrane automatically, and the hidden danger that viruses on the used segment of the transparent separatingmembrane contaminate air in an elevator is avoided.

Description

technical field [0001] The invention belongs to the field of industrial automation devices, and in particular relates to an elevator button diaphragm automatic feeding and discharging and disinfection device. Background technique [0002] In recent years, due to environmental pollution and other reasons, the probability of outbreaks of infectious diseases has increased significantly. For example: the novel coronavirus infectious disease that broke out in 2020, the Middle East respiratory syndrome infectious disease that broke out in 2012, the SARS infectious disease that broke out in 2003, etc. There are many ways to spread infectious diseases, but the elevator button is an important way for the spread of infectious diseases. In order to avoid the transmission of infectious diseases by elevator buttons, people have thought of many preventive methods: for example, method (1) put some toilet paper on the side of the elevator button, and when people need to press the button, t...

Problems solved by technology

In order to avoid the transmission of infectious diseases by elevator buttons, people have thought of many preventive methods: for example, method (1) put some toilet paper on the side of the elevator button, and when people need to press the button, take a piece of toilet paper pad and place it on the elevator button to isolate it to avoid human hands. Direct contact with the elevator button; for example, method (2) sticks a piece of transparent plastic film on the elevator button to isolate to avoid direct contact between the hands and the elevator button; It is convenient; the second all does not carry out timely disinfection to the isolation medium, thus there is a hidden danger of causing secondary pollution to the air in the elevator; the third above-mentioned method (2) is often replaced by a cleaning worker a day, and it is impossible to have someone Press once to change a transparent plastic film, so there is still a hidden danger of spreading infectious diseases through contact with the transparent plastic film
