System of mask for preventing air from being mixed by selectively blocking inner space

The present invention relates to a mask system for preventing air mixing through selective blocking of an internal space. More specifically, it is a technical field related to a system capable of preventing mixing and re-suction of air entering and exiting from a user's nose or a user's mouth by dividing the inner space of the mask into a preset area.

Due to the compulsory wearing of masks to strengthen the prevention of the novel coronavirus infection (COVID-19), the demand for masks has exploded and the number of mask importers and manufacturers has increased significantly.

According to the Ministry of Food and Drug Safety's 'Quasi-drug mask imports and manufacturing establishments registration status', domestic quasi-drug mask imports and manufacturing establishments more than tripled from 188 in 2019 to 627 in September 2020. The number of health mask manufacturers increased by 225.6% from 121 to 394, the number of importers increased from 26 to 38, the number of surgical dental mask manufacturers increased by 357.7% from 26 to 119, and the number of importers increased by 47. was increased to 53.

In addition, according to the data of the Ministry of Food and Drug Safety's monthly production of health masks, this year's mask production increased about 2.5 times from 186.32 million in February 2020 to 465.37 million in August.

Although it is possible to protect personal life and public safety through the mandatory wearing of a mask, the KF94 mask, which is mainly worn to prevent COVID-19, has high airtightness, fine dust and virus blocking rate, but has low oxygen permeability, so if worn for a long time, , carbon dioxide emitted during exhalation may accumulate inside the mask and adversely affect the respiratory system.

As an example of a related prior patent document, "a nose and mouth separation mask (Registration No. 10-2231415, hereinafter referred to as Patent Document 1)" exists.

In the case of the invention according to Patent Document 1, the mask body is made of an elastic material, the ventilation hole is formed at positions corresponding to the nose and mouth; Earrings made of an elastic material connected to the left and right ends of the mask body in a ring shape and having a structure in which bones and mountains are continuously formed; a nose covering frame that is attached near the upper end of the inner surface of the mask body to cover the nose; Replaceable nasal filter inserted into the nose covering frame; a mouth covering frame attached to the inner side of the mask body under the nose covering frame to cover the mouth; It is inserted into the mouth cover frame and replaceable mouth filter; characterized in that it comprises a.

As another example of the patent document, "a high-performance mask for easy breathing (Registration No. 10-2233488, hereinafter referred to as Patent Document 2)" exists.

In the case of the invention according to Patent Document 2, it includes a first filtration part in the form of a filter that is formed through the body part in close contact with the user's face, and the first filtration part is provided toward the outside, the first zone, the inner side of the first zone It is divided into a second zone located in the direction and the first cutout is formed in the outer direction, and a third zone positioned in the inner direction of the second zone and folded in the outer direction so that the inner direction is located in front of the second zone, the third zone It forms a zigzag arrangement located in front of the first zone and the second zone, and a first passage is formed by the first and third zones and the first cutout to provide a mask for moving and filtering outside air and bet air. .

As another example of the patent document, "respiration mask (Registration No. 10-2179117, hereinafter referred to as Patent Document 3)" exists.

In the case of the invention according to Patent Document 3, exhalation and inhalation are allowed to enter and exit only through the nostril cover having a ventilation structure that can completely cover the nostril by close contact around the nostril and the intake/exhaust receiving part of the bag structure provided inside the mask filter. It prevents breathing of fine dust that is not filtered through the gap between the masks, and at the same time expands the breathing capacity to make breathing more comfortable. By allowing it to be sucked in through the intake passage, it is configured to prevent deterioration of the filter function due to moisture in the exhalation, and to greatly widen the breathing area of the mask by providing wavy folds in the filter.
