The present invention relates to an apparatus for drying and sterilizing a mask, and more particularly, while drying and sterilizing the mask, the mask is not contaminated with fine dust or pathogens, so that hygiene and safety can be improved, and separate heat generation It relates to an apparatus for drying and sterilizing a mask, which can perform a drying operation using waste heat generated from a sterilizing light generator without any means, so that the structure is concise and simple, and the energy cost can be reduced.

In general, yellow dust imported from China or generated in Korea contains harmful fine dust including lead, which paralyzes nerves and muscles, cadmium, which causes lung cancer, as well as chromium, which increases the risk of kidney disease and bronchitis. is known

In addition, the extremely fine dust contained in yellow dust has a more serious adverse effect on the human body, so it passes through respiratory shields such as the nose and bronchial tubes and accumulates in the lungs, or directly penetrates blood vessels as well as the kidneys and liver, and the alveoli are damaged (COPD). ) or asthma patients.

Various types of masks have been developed and used as a way to prevent these problems to some extent.

On the other hand, recently, a virus such as Corona 19 has spread around the world, causing serious human casualties and economic loss.

Viruses such as COVID-19 are known to be spread over several meters by being included in droplets generated when an infected person breathes or coughs and spreads to others.

As a result, masks are being worn as a way to block the inflow and inflow of droplets, but due to the rapid increase in demand, they are in short supply in the market. If a virus or the like is attached to the surface, there is a problem that it cannot be reused.

As a method to solve this problem, a mask sterilization apparatus as disclosed in Korean Patent Laid-Open No. 10-2019-0100634 has been proposed.

Hereinafter, the operation of the apparatus for drying and sterilizing a mask according to an embodiment of the present invention will be briefly described.

The accompanying drawings, Figure 7 is a perspective view for explaining the use state of the device for drying and sterilizing a mask according to an embodiment of the present invention.

Referring to Figure 7, when the mask wearer wears the mask for a long time and the mask (m) is wet or contaminated with a virus, it is inserted into the device for drying and sterilizing the mask according to the present invention, which is carried, and drying and sterilization are performed. After that, you can wear the mask repeatedly in a clean state.

Looking at the drying and sterilization process of the mask in more detail, first, the cover case 1b is separated from the main case 1a, and the inner surface of the mask m is placed on the heating net 32, and then the cover case ( Close 1b) to seal the inner space.

In this state, when the on operation is performed by pressing the switch button 52, the light emitting diode 21 emits light while the power of the power supply unit 4 is supplied to the sterilization light generating unit 2 under the control of the control unit 5, and sterilization. After passing through the light emission port 314 of the heating body 31, ultraviolet light, which is light, is irradiated with the heating net 32 to sterilize the surface of the mask.

And, when the light emitting diode 21 of the sterilizing light generating unit 2 emits light, heat is emitted due to the electrical characteristics of the light emitting diode 21 , while the heat is naturally conducted to the LED printed circuit board 22 .

In this way, the heat emitted from the light emitting diode 21 and the heat conducted to the LED printed circuit board 22 are transferred to the heating body 31 in contact with each other, and the heating body 31 is in close contact with each other. Since the heat is transferred to the seating part 321 of the mesh 32 and subsequently conducted to the vertical connection part 322 and the transverse connection part 323, the heating mesh 32 is warmed as a whole. At this time, since the support protrusion 324 and the elastic locking part 325 are inserted through the mesh locking holes 315 and 316 and are in contact with the LED printed circuit board 22, they perform a function similar to that of a heat dissipation fin that directly conducts heat and radiates heat. . In addition, the heating temperature of the heating network 32 is configured by disposing the light emitting diodes 21 so as to be approximately 45° C. although there are differences in the type, capacity w, and quantity of the light emitting diodes 21 .

As described above, when the sterilization action by the sterilization light generating unit 2 and the drying action by the drying heating member 3 are performed for a certain period of time, the user separates the cover case 1b from the main case 1a and , can be worn by removing the mask (m) placed on the heating net (32).

As described above, the device for drying and sterilizing a mask according to the present invention is not provided with a blowing fan, so it is possible to fundamentally block the contamination of the mask with fine dust or viruses due to the inflow of contaminated external air, thereby improving hygiene and safety. can

And, the device for drying and sterilizing the mask according to the present invention can perform the drying operation by utilizing the waste heat generated from the sterilization light generating unit 2 without having a heating means, so that the structure is concise and simple, and the manufacturing cost can be reduced. not only can it reduce energy costs

Although the configuration and operation of the apparatus for drying and sterilizing a mask according to an embodiment of the present invention described above has been described, this is an example and those skilled in the art will not depart from the technical spirit of the present invention.
