Mask for preventing inhalation of pollutants

Abstract

A mask for preventing inhalation of pollutants according to the present invention comprises: a mask main body which covers a user's face and forms a breathing space between the inner surface and the user's face; an air pocket which is installed at one side of the breathing space and in which air, which has passed through the mask main body from the outside, is filled; and an air-guide member which, during inhalation, supplies the air inside the air pocket to the breathing space, and, during exhalation, is operated so as to externally discharge the air inside the breathing space.

Description

technical field [0001] The present invention relates to a mask for preventing the inhalation of pollutants, and more particularly, to a mask for preventing the inhalation of pollutants, which is constructed between a mask body whose edge is closely attached to the user's face and the user's face or between the user's face The outer side of the main body of the mask is provided with an air bag filled with external air, which supplies the external air to the user when inhaling, and discharges the generated air to the outside when exhaling. Therefore, it can prevent the inhalation of external pollutants while breathing, It can also minimize the shortness of breath caused by wearing a mask. Background technique [0002] Generally speaking, masks are used to prevent harmful pollutants such as dust, sand, and fine dust contained in the air from being inhaled into respiratory organs, and have various structures according to the applicable environment and purpose of use.

Problems solved by technology

[0003] Masks based on the prior art mainly utilize pollutant filtering cloth to form a structure covering the user's face. This mask has difficulty in breathing because the filtering cloth is close to the user's mouth or nose and other respiratory organs, and pollutants are easy to wear. Disadvantages of transparency

[0004] As a solution to the above problems, a mouth mask with an inner skin such as a non-woven fabric for filtration has been developed in an outer skin formed in a cap form of a synthetic resin material. The air in the inner skin flows into the multiple through holes of the mask, and then the exhaled air is discharged into the mask. Therefore, the inhaled air and the discharged air are mixed with each other, so that not only the oxygen concentration inside the mask is reduced, but also the oxygen concentration cannot be smoothly discharged. The exhaled air is exhausted to the outside of the mask, so there is a problem that it is difficult to keep breathing smoothly

[0005] Therefore, in order to solve this problem in the prior art, in recent years, as disclosed in the following [Document 1], a dustproof filter has been developed by installing a dustproof filter near the front surface or side surface of the mask so that the user only inhales The dust-proof mask with the structure of the air filtered by the filter for dust-proof, but, as far as the dust-proof mask is concerned, it is not only complicated in structure, expensive, but also similar in shape itself to a gas mask. Therefore, although it can be used in industrial However, when ordinary users wear it to enjoy outdoor activities or sports, there is a problem that the practicality is greatly reduced due to excessive restrictions on mobility
