automatic disinfection door handle

technical field

The invention relates to a door handle, in particular to an automatic disinfection door handle.

Background technique

Contact infection is one of the ways of spreading infectious diseases. In order to avoid contact infection, people need to wash their hands after touching public objects, such as handrails, elevator buttons, and public touch screens (such as ATMs, tour guides, etc.). Virus. In areas where hand washing is not convenient, alcohol, dry hand sanitizer or disinfectant that can kill viruses or make viruses 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 water for disinfection is quite labor-intensive, and thus the cost is high. 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 demand, such as China Publication No. CN 112459614A, CN 103015791 A, CN 112334159 A and other patents, disclose various technologies for disinfection using ultraviolet lamps. However, these disinfection methods are likely to have the problem of insufficient disinfection due to too long a distance or improper exposure of users to ultraviolet rays.

Contents of the invention

The main purpose of the present invention is to disclose an automatic disinfection doorknob, which can automatically disinfect and avoid the problems of insufficient disinfection or improper exposure of the user 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 fits on the handle straight rod to be able to move directly on the handle slide on the rod, and the sliding ring has an accommodating space, the accommodating space surrounds and is adjacent to the straight handle rod, the disinfection lamp is arranged in the accommodating space, and the disinfection lamp surrounds the straight handle rod, the The transmission element is arranged on the sliding ring, and drives the sliding ring to slide relative to the straight rod of the handle.

According to this, the sliding ring of the present invention can slide on the straight rod of the handle, so as long as it is driven by the transmission element, it can slide relative to the straight rod of the handle, and then use the ring that is arranged in the accommodating space and surrounds the straight rod of the handle The disinfection lamp on the handle automatically disinfects the straight rod of the handle, which can meet the needs of automatic disinfection, and because the disinfection lamp is arranged in the accommodating space, and the disinfection lamp surrounds the straight rod of the handle, the disinfection lamp In order to sterilize the straight bar of the handle with the shortest distance, there is no problem of incomplete disinfection, and there is no problem of ultraviolet exposure when it is covered by the sliding ring during disinfection.

Detailed ways

Relevant detailed description and technical content of the present invention, now just explain as follows with respect to matching figure:

Please refer to "Fig. 1", "Fig. 2" and "Fig. 3", which is the first embodiment of the present invention, which provides an automatic disinfection door handle, including a handle straight rod 10, a sliding ring 20, and a disinfection lamp 30 and a transmission element 40, wherein the sliding ring 20 fits on the handle straight rod 10 and can slide on the handle straight rod 10, and in order to reduce friction, the sliding ring 20 is provided with multiple The straight rod 10 contacts the ball screw 21 .

The sliding ring 20 can be assembled by an upper ring 201 and a lower ring 202. The sliding ring 20 has an accommodating space 22. The accommodating space 22 surrounds and is adjacent to the straight handle 10. The disinfection lamp 30 It is arranged in the accommodating space 22 , and the disinfection lamp 30 surrounds the straight handle 10 .

In order to automatically start the disinfection operation, the present invention includes at least one infrared sensor 23, the at least one infrared sensor 23 is arranged on the sliding ring 20, and the at least one infrared sensor 23 is aligned with the handle bar 10, it can be judged Whether someone touches the straight handle 10 , in a preferred embodiment, there are two at least one infrared sensor 23 , which are respectively arranged on the upper and lower sides of the sliding ring 20 .

In the first embodiment, the transmission element 40 is arranged on the sliding ring 20, and drives the sliding ring 20 to slide relative to the straight handle 10.
