Description

{STERILIZING MASK WITH ELECTRIC PRECIPITATION}

The present invention relates to a mask, and more particularly, to an electric dust-collecting and sterilizing mask capable of collecting and sterilizing fine dust, germs, viruses, and the like in air sucked by a user when the mask is worn by electrostatic dusting .

Conventional general masks are products in which dust or the like in the air is blocked by using a cloth type or a dense, very small porous structure and a nonwoven fabric having an electrostatic function.

The higher the dust collection rate of the mask, the more difficult it is for the air to pass through, thus hindering the user's natural breathing. For example, the N95 grade or KF99 grade, which has a fine dust barrier effect, is very uncomfortable to use because of its very high intake resistance.

In addition, the performance of the fine dust particles (0.1um or less) substantially harmful to human body is uncertain, and most of them have a function to block fine dust, germs and viruses and can not sterilize bacteria or viruses.

There are some products that perform sterilization by coating a sterilizing material on a nonwoven fabric used for a mask. However, since the sterilizing performance varies depending on the kind of the sterilizing target, it is insufficient to perform a sterilizing function stably.

In the case of a mask using an electrostatic nonwoven fabric, the electrostatic force of the electrostatic nonwoven fabric has a disadvantage in that the performance rapidly deteriorates depending on environmental changes such as the moisture content in the atmosphere, the degree of dust collection, and the storage period. In addition, the electrostatic nonwoven fabric to be used has an electrostatic level of -300 to -600 V, which is a very low potential for blocking fine dust, and the collection efficiency is low.

5 is a state diagram showing the sterilization and collection state of the mask using electric dust collection.

5, the ground GND of the voltage generating unit 300 is connected to the metal plate 213 spaced apart from the charge unit 210 of the electric dust collector 200 at regular intervals, When a high voltage is applied to the discharge wire 215 in a state where the (-) pole of the voltage generating part 300 is connected to the discharge wire 215 which is installed at the intersection, electrons are discharged from the discharge wire 215 due to the discharge phenomenon.

At this time, if the collection object 1 such as fine dust, bacteria, virus, etc. contained in the air sucked at the time of intake by the user collides with the discharged electrons while passing through the charging part 210 of the electrostatic precipitator 200, And the collection target body 1 is negatively charged.

The collecting object 1 negatively charged through the charging unit 210 is disposed on the rear surface of the charging unit 210 so as to be perpendicular to the moving direction of the collecting object 1 and connected to the metal plate 213 to form a ground And is primarily collected by a dust collecting filter 221 having a planar structure woven with a collecting portion 221, that is, a metal fiber 221a and synthetic fibers 221b. At this time, the fabric dust collecting filter 221 primarily collects the particles of the target object 1 charged by the Coulomb force. In addition, electrons attached to bacteria or viruses are taken away by the trapping part and are killed by the rapid potential change. Unlike the chemical sterilization method, this occurs uniformly irrespective of the type (species) of the capture target 1, and thus can exhibit a uniform germicidal effect.

The collection target body 1 passing through the first collection portion 221 without being collected is collected by the second collection portion 222 provided on the rear surface of the first collection portion 221, It is collected by a car.

By using the flat type fabric dust collecting filter 221 and the nonwoven fabric dust collecting filter 222 arranged in the direction perpendicular to the moving direction of the collecting object 1, the air permeability is excellent, There is no. In addition, the dust collecting performance of the fine dust can be increased through the electric dust collector 200, and sterilization of germs and viruses as well as fine dust removal can be performed by strong static electricity. Further, sterilization and collection of fine dust, germs, viruses, and the like through the electric dust collecting unit 200 can exhibit uniform collection performance at all times regardless of environmental changes such as moisture content and temperature in the atmosphere. In addition, since the user can use only the contaminated nonwoven fabric dust collecting filter 222 after using the mask, economical benefits can be expected. The electrostatic dust collecting unit 200 including only the fabric dust collecting filter 221 except for the nonwoven fabric dust collecting filter 222 can be used as a product that can be attached to a general mask.
