Description

Mask sterilizer {mask sterilizer}

The present invention relates to a mask sterilizing device, and more specifically, to a portable mask sterilizing device that can sterilize masks using UV-LEDs that emit ultraviolet rays (UV).

In general, many countries have been using masks for a long time to block pollutants such as smoke, pollen, and fine dust remaining in the atmosphere from entering the respiratory tract along with the air, and to allow clean, purified air to enter the respiratory tract. I have been using it.

In addition, in recent years, the use of masks has become widespread due to ultrafine dust that causes serious diseases in the human body, and due to the outbreak of SARS, MERS, and especially COVID-19, masks has become a daily necessity that must be worn all year round.

These masks are made of cotton fabric that can be reused by washing, or recently, disposable masks made of non-woven fabric are widely used to be discarded after use.

However, due to the characteristics of masks made of various materials, moisture is easily formed in the mask even when used for a short period of time, and bacteria, viruses, etc. proliferate.

Therefore, if moisture, bacteria, and viruses are not quickly removed immediately after use, it can have a negative impact on health and cause discomfort in use due to bad odor.

In particular, if masks that have been used only for a short time are easily discarded due to lack of management, it will cause not only economic losses but also major environmental problems in times of frequent mask use, such as the present.

In 2020, 1,674.63 million masks were produced in Korea alone, and most of them were disposable masks. The masks are made of plastic, including polypropylene and polyethylene vinyl, and even if discarded correctly, some are treated as medical waste, which poses a social risk. Significantly increases economic costs.

Therefore, prior art has been proposed to solve the above problems.

A prior art tray-type ultraviolet sterilizer (Patent Publication No. 10-2011-0098394) has a bottom surface that can be placed on a structure including a desk, table, and shelf, and the upper side of the bottom surface has an upper surface, The sides of the bottom surface and the upper surface are composed of side surfaces, the back part is treated as the back side, the front part has a mask surface with a sliding space opened, and the casing body has an interior as a storage space, and the front part of the casing main body. A tray that is coupled to slide along the sliding space 17 formed on the mask surface to seat the sterilizing object in the internal storage space, and a reflector installed on the inner upper wall of the casing body to reflect ultraviolet rays irradiated from the ultraviolet lamp. It is characterized by consisting of.

In the prior art, the management means of the mask is limited to simple sterilization, and in particular, it lacks the function of removing moisture and odor caused by the user's droplets, etc., so it is difficult to solve the above problems. There are many shortcomings.

Therefore, when using a mask, it is possible to easily and efficiently sterilize the mask regardless of place and time, and the mask sterilization device is implemented to efficiently remove moisture, odor, etc. by simultaneously deodorizing and drying through ventilation. is being demanded.
