Description

Mask with sterilization function {MASK HAVING STERILIZATION FUNCTION}

The present invention relates to a mask, and more particularly, to a mask having a sterilization function capable of killing pathogens in front of the mask wearer's respiratory tract using plasma.

A mask is an object that covers the respiratory tract to prevent inhalation or scattering of germs or dust through the mouth and nose respiratory tract for health and hygiene reasons. It is used to prevent inhalation, or worn as a substitute for a kind of cold protection when caught in a cold in winter when the temperature is low, and is also used to protect the wearer from yellow dust generated in spring.

In particular, in recent years, it is recommended to wear a mask to prevent infections such as seasonal flu, avian flu, swine flu, MERS, SARS, and corona, which are acute respiratory diseases that have become a social problem. A mask having a sterilization function has been previously disclosed for preventing diseases and bacterial infections caused by infiltration of microorganisms, bacteria or viruses. However, such a mask uses a large air fan to overcome respiratory resistance, but the size, cost, noise, and power consumption of the air fan are not popularized due to various factors such as power consumption.

On the other hand, since most masks use a fiber filter to block pollutants in the air, the pressure drop of the air during intake is so severe that breathing is inconvenient, making it difficult for children and the elderly with weak breathing ability to use.

Accordingly, it is an object of the present invention to present a technology for a mask that can prevent the wearer of the mask from entering the respiratory tract, such as microorganisms, bacteria, or viruses, while allowing the wearer to breathe smoothly without discomfort.

In this case, the body 110 may include at least one plasma generator 111 and 112 for generating plasma, thereby killing pathogens in the atmosphere (or air) flowing in and out through the micro-through hole 115 .

However, since the components shown in FIGS. 1 and 2 are not essential, a mask having a sterilization function having more or fewer components may be implemented.

Hereinafter, each component will be described.

The body 110 may have a generally tubular shape having a hollow inside, and may have an approximately U-shaped appearance as a whole so that the user can closely adhere to the wearer's chin when worn. In addition, both ends of the body 110 may include earring straps 130a and 130b so that the mask according to the present invention can be worn over the wearer's ear.

The body 110 has a hollow part therein, and various components may be embedded in the body 110 .

It is preferable to be equally distributed on both the left and right sides. Of course, alternatively, a battery may be provided throughout the body 110 having an overall curved shape, and in this case, the battery is preferably a flexible battery that can be bent.

The batteries 114a and 114b are not particularly limited, but output power of a DC voltage. As will be described later, in order for the plasma generators 111 and 112 to generate plasma, the mask 100 according to an embodiment of the present invention. ) may include a high voltage DC-DC converter.

The high voltage DC-DC transformer emits a DC voltage input at a level of several volts from the batteries 114a and 114b to a high DC voltage of several thousand volts, thereby generating plasma from the asymmetric electrodes of the plasma generators 111 and 112 to be described later. can do. As an example, the high voltage DC-DC transformer may boost the low voltage of 5V or less supplied from the batteries 114a and 114b to 1.5 to 5kV and supply it to the asymmetric electrodes of the plasma generators 111 and 112 .

In addition, the inside of the body 110 may include at least one plasma generator (111, 112) for generating plasma (plasma).

Plasma generators 111 and 112 according to an embodiment generate plasma appearing as ionized air is concentrated on the surface of one of the asymmetric electrodes when high voltage electricity is supplied to an asymmetric electrode composed of a pin electrode and a plate electrode. can Depending on the asymmetric electrode, an electron or a positive electrical cloud may be generated, and the positive electrical cloud may electrically charge fine particles in the air passing therethrough. As described above, the asymmetric electrode may include a pin electrode and a plate electrode, and in general, plasma may be generated at the pin electrode. The pin electrode and the plate electrode are not particularly limited, but as an example, conductive metals such as copper, gold, aluminum, and steel, elements corresponding to group IV of the periodic table (silicon, carbon, etc.) or conductive glass and polymer etc. can be When the fine particles in the air that are negatively charged by the plasma generated from the pin electrode pass near the particle collection plate, they can move to the particle collection plate having an anode and be adsorbed on the particle collection plate. Similarly, fine particles in the air, positively charged by the microplasma, when passing near the particle collecting plate, move to the particle collecting plate having a cathode and can be adsorbed to the particle collecting plate.

On the other hand, while the plasma can electrically charge the fine particles in the air, it can generate ozone by changing oxygen in the air to ozone. Ozone at a certain concentration level may have a sterilization effect, but since an average of 0.070 ppm or more for 8 hours may cause respiratory diseases, the mask according to an embodiment of the present invention includes an ozone removing element, Ozone generated by plasma can be removed. Here, the ozone removing unit is not particularly limited as long as it can remove ozone, but may be, for example, a film or a filter made of manganese oxide (MnO) or manganese dioxide (MnO2).

As described above, the plasma generators 111 and 112 may generate plasma by applying a high voltage to the tip of the pointed metal tip. there is a problem

Therefore, in the plasma generators 111 and 112 according to another embodiment of the present invention, a dielectric is inserted between a high voltage (about 3 kV or more) electrode and a ground electrode and an alternating voltage is applied to the high voltage electrode so that electrons are generated between the two electrodes. It may be a method of generating plasma by ionizing the injected gas that is accelerated in the electric field region. That is, plasma can be generated by dielectric barrier discharge, and a detailed description thereof will be omitted as it is outside the scope of the present invention (Japanese Patent Laid-Open No. 2007-250284, Korean Patent Registration No. 1355187, etc.) See a plasma generating module).
