Description

Technical Field

[0001] The present invention relates to the technical field of elevator car disinfection, and in particular to an automatic disinfection device for a household elevator car. Background Art

[0002] The elevator car is a box-shaped space used by the elevator to carry and transport people and materials. The elevator car is generally composed of the main parts such as the car bottom, car wall, car top, and car door. It is the car body part used by the elevator to carry passengers or goods and other loads. However, during special circumstances, the interior of the elevator car is disinfected frequently, which requires the use of automatic disinfection devices.

[0003] The automatic disinfection device in the prior art can be installed inside the elevator and move with the elevator by providing a fan, an atomizer, a liquid storage tank and other devices, so as to achieve the purpose of conveniently disinfecting the elevator car.
