Description

Automatic disinfection door handle

This creation relates to a doorknob, especially an automatic disinfection doorknob.

Contact transmission is one of the ways of spreading infectious diseases. In order to avoid contact transmission, people need to wash their hands to remove after touching public items, such as handrails, elevator buttons, and public touch screens (such as ATMs, navigation machines, etc.). Virus. In areas where it is not convenient to wash hands, alcohol, hand sanitizer or sanitizer that can kill or make the virus inactive will be used to disinfect hands. For public use, such as handrails, elevator buttons, and public touch screens, they are regularly disinfected by wiping with diluted bleach.

However, the method of regularly wiping with diluted bleach for disinfection is labor-intensive and expensive. Moreover, the disinfection method of manual wiping is prone to omissions, and it is difficult to ensure the sanitation and safety of the environment.

In order to reduce the manpower requirement, for example, Chinese Patent Publication Nos. CN 112459614A, CN 103015791 A, CN 112334159 A, etc., disclose various technologies for disinfection by ultraviolet lamps. However, these disinfection methods are prone to problems that the distance is too long and the disinfection is insufficient or the user is improperly exposed to ultraviolet rays.

The main purpose of this new model is to disclose an automatic disinfection door handle, which can be automatically disinfected and can avoid the problem of insufficient disinfection or improper exposure of users to ultraviolet rays.

In order to achieve the above purpose, the present invention provides an automatic disinfection door handle, which includes a handle straight rod, a sliding ring, a disinfection lamp and a transmission element, wherein the sliding ring is sleeved on the handle straight rod and can be connected to the handle straight rod.
