Description

Folding optical care device {FOLDING OPTICAL CARE DEVICE}

The present invention relates to a folding type light care device, and more particularly, to a folding type light care device in the shape of a portable pouch that provides sterilization and drying functions as well as wrinkle-free storage of not only a health mask but also a corresponding product. It's about the device.

In general, a mask refers to an object made of a special material to cover the nose and mouth in order to prevent inhalation and scattering of germs, dust, etc. for health and hygiene reasons.

Masks block viruses by using static electricity to make viruses adhere to the filter surface, but when exposed to moisture from saliva or weather, viruses or bacteria multiply easily on the mask, and when such a mask is used, it is harmful to the skin. It can have a bad effect.

On the other hand, in an atmosphere where a mask must be used frequently or every day, such as when performing work in an environment with a lot of fine dust or during a period during which viral infections are spreading, it is necessary for the person concerned to use one mask hygienically for a maximum period of time. can This is because if a large number of people need a large number of masks in a short period of time, a problem in supply and demand of masks may occur.

In this case, if the mask is disinfected with alcohol or washed with water to reuse the mask, the material is damaged and the function of the filter that causes static electricity is significantly deteriorated. It reduces the function of the mask, and as a result, the virus blocking effect is also reduced.

On the other hand, there is an opinion that sterilization using an ultraviolet sterilizer is a way to effectively remove viruses or bacteria attached to the mask without damaging the filter, and some experts say that if reuse is inevitable, it is possible to sterilize the mask without physically or chemically deforming it. It is believed that a UV sterilizer that can be used may be an alternative.
