Description

The present invention relates to a mask, and more particularly to a mask capable of sterilizing a virus bacterium.

Generally, it is said that commercially available masks have a certain effect on the scattering of droplets containing bacteria, but they only have the function of eliminating virus bacteria and actively kill the bacteria. It does not have a function to make it, and in terms of sterilization, it has no effect and includes problems that it cannot be used with complete peace of mind. In addition, masks with disinfectant and bactericidal functions are sometimes used in a small part, but the fact is that they are not sufficiently effective against highly infectious target viruses such as the new coronavirus. Is. In addition, wearing a mask during the hot summer months can cause the skin in contact with the mask to become stuffy and uncomfortable, and in some cases, there is a risk of heat stroke.

Utility Model Registration No. 3223707 Gazette Japanese Unexamined Patent Publication No. 2012-139478

In the case of Patent Document 1, the sterilizing mask includes a sterilizing layer 110 containing silver-containing fibers and bamboo fibers, a first filter layer 120, and further includes a second filter layer 130 and an outer surface layer 140. The first filter layer 120 is a nanofiber fiber. The sterilizing layer 110 contains a plurality of silver ions, particularly nano-order silver ions. The first filter layer 120 further includes a nanofiber layer and a non-woven fabric. In this case, the mask appeals for a filter function for excluding bacteria, and only has a function for excluding existing bacteria, and does not include a function for actively killing virus bacteria and the like. Further, in the case of Patent Document 2, a structure in which the lighting device can be easily attached and detached separately from the mask 4, a small light bulb or LED lighting that generates purple lighting is installed, and the power supply 2 is set so that the purple light is lit. Is docked on the surface of the mask 4. The surface of the mask 4 is irradiated with ultraviolet wavelengths of purple visible light and invisible light by purple illumination. The virus on the surface of the mask 4 is sterilized by applying the characteristics of the wavelength of ultraviolet rays. The back side of the mask 4 has a structure in which the color neutralized by the ultraviolet rays or a material such as gauze or cloth that the wavelength does not reach is covered in consideration of the influence of the ultraviolet rays and the harmful effects on the skin. The mask 4 and the lighting device have a structure that can be easily attached and detached by themselves, and if the mask 4 becomes dirty, it can be separated and washed, so that it can always be used cleanly. However, the function of the above j-mask is to sterilize the bacteria adhering to the surface of the mask with purple lighting using LEDs with ultraviolet wavelengths of purple visible light and invisible light, so it irradiates the skin directly from the LED. There is also the problem that it cannot be denied that the irradiated light may hit the skin and affect the skin. In addition, sterilization of virus bacteria cannot be sterilized instantaneously and requires a certain amount of time, and the time-killing effect and the passage of time are also considered to be one of the issues. Further, since the purple illumination irradiates the front surface of the mask with the irradiation of the ultraviolet wavelengths of the purple visible light and the invisible light toward the front surface of the mask, there is a possibility that the surroundings may be affected.

An object of the present invention has been made in view of the above, and to provide a mask that allows sufficiently sterilized safe air to move toward the face in the mask and breathe safe air. It is to be. In addition, the mask can give a refreshing feeling to the skin of the person wearing the mask by a series of air flows from the intake of air into the mask to the discharge of air.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a mask that allows sufficiently sterilized safe air to move toward the face in the mask and inhale the safe air.

It is a side sectional view of the sterilization mask by embodiment of this invention. It is a front view of the sterilization mask according to the embodiment of the invention.

Hereinafter, the sterilizing mask according to the embodiment of the present invention will be described with reference to FIGS. 1 and 2.
In all the drawings below, the dimensions and ratios of the components are shown differently as appropriate for the sake of easy understanding.

As shown in FIGS. 1 to 2, the sterilization mask according to the present embodiment includes a mask main body 1, a hanging string 2, an air tank 3, a filter 4, a fan 5, an ultraviolet LED 6, a battery 7, and ventilation. It is composed of a unit 8, exhaust units 9a and 9b, and a switch unit 10. The ultraviolet LED 6 is preferably an LED having a peak wavelength in deep ultraviolet rays (UV-C: 100 to 280 nm), but may be an LED having a peak wavelength in near ultraviolet rays (about 300 to 400 nm), or 280 to. It may be an LED having a peak wavelength at 315 nm, or it may be an LED having a peak wavelength at 315 to 400 nm.

In the sterilization mask according to the present embodiment, the mask body 1 is hung on both ears with a hanging string 2. Next, the air from the outside of the mask is taken into the air tank 3 in the mask by the blowing function of the fan 5 through the filter 4. The air tank 3 is a closed air space, and the upper wall inside the air tank 3 is irradiated toward the air in the air tank by the ultraviolet LED 6. This air tank has a structure that does not allow light to leak to the outside. A porous member 8 is provided on the face side of the air tank so that the sterilized air gradually comes out and reaches the nose and mouth of the face to allow breathing. The air exhaled by a person's breath is discharged to the outside of the mask from the exhaust portions 9a and 9b on both sides of the mask body. The switch is a manual switch for activating or not activating the ultraviolet LED 6 and the fan 5. With the above functions and configurations, the air taken in from the outside to the inside of the mask is a mask that can sterilize virus bacteria with an ultraviolet LED and safely inhale the sterilized air.

The mask body 1 is preferably made of a material having a high sealing property, for example, a synthetic resin such as plastic is preferable, but a synthetic resin or a natural resin made of a material having a low rigidity may be used, or a normal mask. The cloth used for the above may be used. Further, the filter 4 is preferably a non-woven fabric of chemical fibers such as polypropylene or polyester, but a cloth such as gauze, paper, an activated carbon filter or the like may be used, or a filter other than these may be used. good. Further, as the porous material provided in the ventilation portion 8, polyurethane foam, styrofoam, or the like may be used, activated carbon or bamboo charcoal may be finely crushed to ensure breathability, or other materials may be used. Materials may be used. In addition, the porous material may not be provided in the ventilation portion 8, or the filter 4 may not be provided.

According to this embodiment, for example, a short-wavelength deep ultraviolet LED capable of killing bacteria up to 99.9% against a highly infectious new corona virus is aired in an air tank inside a mask for a certain period of time. The air is sterilized by irradiating it, and the air is taken out around the nose and mouth on the face side through the ventilation part 8, and the person wearing the mask can safely inhale the sterilized air. It provides a mask that can be used. This is not just a mask that has the function of simply preventing the conventional splashes, but has the function of sterilizing the bacteria that have invaded the mask, amid concerns about the spread of the new coronavirus infection. It is an invention of a sterilizing mask.

INDUSTRIAL APPLICABILITY The present invention is a mask worn as a countermeasure against viruses in daily life in industry, and can be used as a sterilizing mask capable of inhaling air in which virus bacteria in the inhaled air are also killed. In addition, it is a mask that can give a refreshing feeling to the skin of the person wearing the mask without getting stuffy even in hot weather by a series of air flow from the intake of air to the inside of the mask to the discharge.
