[0001] The present invention relates to a contact type mask having an intake port and an exhaust port,

The present invention relates to a contact type mask having an inlet and an outlet, and more particularly, to a contact type mask having an inlet and an outlet, and more particularly, It has a suction port that can be easily replaced with a filter, and an exhaust port that allows efficient exhaustion at the time of exhalation. It has an intake port and an exhaust port that can be used for simple cleaning by changing the material of the mask body The present invention relates to a contact type mask having the above-

Generally, a face mask and mask covering the nose and mouth are commonly used to prevent contaminants from entering the wearer ' s respiratory system and to protect others or items from exposure to pathogens and other contaminants emitted by wearers It is worn on the person's respiratory passages for two common purposes.

In the first condition, the face mask is worn in an environment where the air contains harmful substances to the wearer, such as for example in an automotive paint shop. In the second condition, the face mask is used in a different environment, It is worn in environments where there is a high risk of infection or contamination of people or goods.

As industrial pollution continues to increase, the level of hygiene equipment is required as the threat of various viruses increases.

Recently, new viruses such as coronaviruses of severe acute respiratory syndrome (SARS), swine influenza (SI), avianinfluenza (AI) have appeared, and a mask Demand is increasing.

Recently, it is necessary to wear a mask that can prevent a disease such as a respiratory disease to harmful substances by wearing a mask on a day when the atmospheric dust is particularly badly generated. And the like.

It is true that when wearing a mask practically, it is inconvenient to inhale or expel more than when the mask is not worn.

In addition, the inner surface of the mask is breathed, and the inner fabric of the mask is gradually moistened, and the breathability is deteriorated due to the wetting. In addition, the breath is raised through the horn between the nose and the face protruding from the face, In this case, fogging occurs in the spectacles to blur the field of view, and ultimately external air flows through the excited region to lose the function of the mask.

In order to overcome the above-mentioned problems, the patent document related to the mask is disclosed in Korean Patent Laid-Open Publication No. 10-2017-0114826 (name: filter replacement type dust mask, published on Oct. 16, 2017, Patent Document 1 ') and Registration No. 10-1801828 (name: Dust mask, registered on November 21, 2017, hereinafter referred to as Patent Document 2).

Vertical supports made of silicone are vertically installed on both sides of the filter unit lid unit to reduce deformation of the filter unit lid unit On the upper side of the body, a flexible sealing device is mounted, It is configured to block the dust.

That is, in the filter unit in Patent Document 1, a well-known filter composed of a silicon slime filter, a main filter and a nonwoven filter is used on the rear side of the body, and an exhaust valve in which an annular silicone is guided therein is mounted. The air is circulated through the filter unit at the time of inhalation and through the exhaust valve at the time of exhalation.

However, the filter cover part for replacing the filter part has a structure in which the air can be circulated, but the filter part and the filter part cover part made up of a plurality of layers are further padded and the air circulation is not smooth at the time of inhalation, The flexible sealing member is also difficult to adhere to the curved line extending from the nose of the wearer to the face. As described above, there is a problem in that external air is introduced into the mask through the excited portion of the sealing member.

As a result, the air is exhausted at the time of exhalation through the exhaust valve, but the inflow is not smooth or the air can not flow through the filter part and the lid part, and flows into the hermetically sealed part of the sealing device.

And a sealing part coated with a nano coating material on the inner side of the main body part. Therefore, it is possible to prevent the makeup from being erased from the wearer's face, improve the adhesion to the face, So that the feeling of adhesion can be further improved.

However, the configuration of the mask as described above is very expensive in the portion where the general purchaser purchases, and in addition to the inaccurate measurement of the dust and the yellow dust concentration applied by the sensor, And it is only possible to carry information on whether or not the dust masks are worn. Also, since the structure for replacing the replaceable filters is not disclosed, There are several problems pointed out.
