Description

Mist Shower Device for Sterilization and Disinfection with Adjustable Spray Condition }

The present invention relates to a mist shower device for sterilization and disinfection capable of controlling the spray state, and more particularly, it is installed in a place where a large number of people enter and exit, and sprays a sterilizing mist to a person passing through the inside, It can remove various viruses and bacteria.

Recently, as the Corona-19 virus spreads around the world, it has a great impact on daily life, and effective quarantine measures for a large number of people who enter and exit a specific place in daily life are more urgent than anything else.

Unlike the livestock epidemic, COVID-19 spreads from person to person throughout the region, so it is necessary to prevent entry and exit from most places where people come and go.

In this regard, the conventional disinfection room that is installed in a limited place such as a livestock barn and performs whole-body disinfection and sterilization for visitors is not easy to install and is cumbersome to use, so it is difficult to efficiently use it in many places.

In addition, since a large number of visitors cannot wear protective clothing individually, sterilization and disinfection must be performed while wearing everyday clothes. In this process, depending on the composition or condition of the material used for sterilization, it may be harmful to the human body. There should not be any side effects such as harming or contaminating clothes.

Regarding the sterilization and disinfection device for visitors, the 'outdoor walking-through sterilizer' of Korean Patent Registration No. 10-2191093 is installed outdoors and forms an atmosphere of disinfectant water as a person passes through it, thereby sterilizing the entire body of a passer by virus. make it possible

However, most of the conventional sterilization and disinfection apparatuses such as Patent Registration No. 10-2191093 use sterilization water that is separately manufactured and distributed in individual containers.

For example, since the disinfection water used in Patent Registration No. 10-2191093 is distributed while being stored in the disinfection water storage unit (canister), the contents must be periodically refilled or the entire barrel must be refilled before use.

In this way, when the disinfection water distributed in individual containers is used, the supply and management of disinfection water is very inconvenient. It takes a lot of time and manpower to periodically supply sterilization water to sterilization devices installed in multiple places, and inevitably it is costly.

With respect to the technology for generating sterile water that can be used for sterilization, an electrolysis method may be used.

For example, Republic of Korea Patent Registration No. 10-2161372 discloses a 'portable beauty hydrogen sterilizing water mist device' that generates sterilizing water by discharging raw water underwater and discharging it to the outside in the form of mist.

However, as in Patent Registration No. 10-2161372, the conventional technology of generating sterilizing water using electrolysis is mainly used for generating small-scale sterilization water such as for cosmetic purposes, and sterilizing a large amount of sterilization such as prevention of a large number of people It is not actively used in fields that require numbers.

Since the electrolysis method can conveniently and economically supply sterilizing water, it is necessary to properly utilize it according to the situation in which quarantine is performed in daily life due to the pandemic of COVID-19.

On the other hand, a mist shower device that performs sterilization and disinfection by spraying mist to a target for quarantine in a specific area needs to spray the mist in an optimal state to the person to be quarantined according to various situations.

The straightness of the mist can be strengthened to increase the mist spraying efficiency, but if only the straightness is strengthened, the spread of the mist will be weakened, and the mist may not be able to sufficiently contact the body of the person to be quarantined.

If the mist is not sprayed properly and evenly, the sterilization and disinfection power does not reach the entire body of the person to be quarantined, and the prevention effect may be reduced.
