Description

Entrance gate type sterilization device{STERILIZING APPARATUS FOR GATE}

The following embodiments relate to an entrance gate type sterilization device.

In the case of medical facilities that require strict hygiene management and manufacturing facilities that require a high level of dustproof treatment, a lot of attention is paid to the management of the entrances and exits of workers.

Various products have been developed and used to remove and sterilize dust from visitors, but the sterilization and dust collection functions are separated or unclearly mixed, so the dust collection efficiency and the sterilization efficiency are not greatly improved.

A method of scattering dust by applying strong wind to visitors near the interior and exterior boundaries, such as an air curtain, is commonly used, but a significant amount of dust scattered inside may be attached to the body of the visitor again. When the disinfectant is sprayed in such a state, dust is more easily adhered by the disinfectant, so that the dustproof and sterilizing effect is reduced.
