Description

Electric hand sterilizer

The present invention relates to an electric hand sterilizer, and more particularly, it is disposed in public places, restaurants, offices, etc. that require hygiene, and sprays the stored disinfectant on the hand part of the user entering the disinfection space in a fine manner. It relates to an electric hand sterilizer that sterilizes residual bacteria to ensure a stable hygiene condition of the hand area.

In modern times, the population is densely populated, group meals and meals are frequent, and the movement of the population is large due to the development of transportation.

Accordingly, there is a trend that bacterial infectious diseases are frequently occurring and widespread, and since most of the infectious diseases are transmitted through hands, most bacterial infectious diseases can be prevented by just cleaning the hands.

In general, more clean hygiene is required in facilities used by a large number of unspecified people such as restaurants, hospitals, rest areas, and convenience stores, and most germs can be removed simply by washing your hands thoroughly with soap and running water. Can, but the germs are not completely eliminated.

In addition, establishments such as restaurants provide wet towels, and customers use wet towels to wipe their hands, but it is difficult to completely remove various germs from their hands by this action.

Therefore, as described above, bacteria can be removed to a considerable extent only by wiping hands in the washroom, but it is very cumbersome, and this is not suitable for practical conditions, so most of them are simply dependent on a wet towel.

In order to solve this problem, sterilizers that quantitatively spray disinfectant water are popular, and in recent years, the disinfectant water is automatically disinfected without artificial manipulation or operation through commands from the control panel received as signals from the pumping motor, spray nozzle, and detection sensor. Electric hand sterilizers (also referred to as non-contact hand sterilizers) that spray onto the hand part that entered the space are popular.

However, a large amount of contaminated disinfectant water remains in the disinfection space where the disinfectant water is repeatedly sprayed. Since it is configured to absorb and treat disinfectant particles sprayed through a sponge in the lower part of the disinfection space, disinfection if used repeatedly for a long time Pollution may be caused in the space, and a problem that odor may occur has been pointed out.

In addition, since the conventional hand sterilizer is configured to spray the disinfectant solution at a standardized angle and direction, it has a limitation in that it cannot uniformly spray the disinfectant solution on the entire area of the hand entering at various depths and angles.
