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

Due to the mandatory wearing of masks to strengthen quarantine against the novel coronavirus infection (COVID-19), the demand for masks has exploded, resulting in a significant increase in the number of mask imports and manufacturers.

According to the Ministry of Food and Drug Safety's 'Registration Status of Quasi-drug Mask Imports and Manufacturers', the number of domestic quasi-drug mask imports and manufacturers increased more than threefold 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 dental mask manufacturers increased by 357.7% from 26 to 119, and the number of importers increased by 47. was found to increase to 53.

In addition, according to the Ministry of Food and Drug Safety’s ‘Monthly Production of Health Masks’ data, this year’s mask production increased by about 2.5 times from 186.32 million in February 2020 to 465.37 million as of August.

Personal life and public safety can be protected through the mandatory wearing of masks, but the KF94 mask, which is mainly worn to prevent Corona 19, has high sealing power, fine dust and virus blocking rate, but low oxygen permeability, so when worn for a long time However, carbon dioxide in the body exhaled during exhalation can accumulate inside the mask and negatively affect the respiratory system.

As an example of prior patent documents related to this, there is a “nose-mouth separation type mask (Registration No. 10-2231415, hereinafter referred to as Patent Document 1)”.

In the case of the invention according to Patent Document 1, the mask body is made of an elastic material and has ventilation holes formed at positions corresponding to the nose and mouth; Earrings made of elastic material that are connected in a ring form to both left and right ends of the mask body and have a structure in which a valley and a mountain are formed continuously; A nose covering frame that is attached near the upper end of the inner surface of the mask body and covers the nose; A replaceable nose filter inserted into the nose shield frame; A mouth covering frame attached to the inner surface of the mask body under the nose covering frame to cover the mouth; It is inserted into the mouth covering frame and is characterized by including a; replaceable mouth filter.

As an example of another patent document, “a high-performance mask that is easy to breathe (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 filter-shaped first filtering part formed through a body part in close contact with the user's face, and the first filtering part is provided in an outward direction, a first zone, and an inner side of the first zone. It is divided into a second zone located in the outer direction and having a first incision formed in the outer direction, and a third zone located in the inner direction of the second zone and the outer direction being folded so that the inner direction is located in front of the second zone. A zigzag arrangement located in front of the first and second zones is formed, and a first passage is formed by the first zone, the third zone, and the first cutout to provide a mask for moving and filtering outside air and indoor air. .

As an example of another patent document, there is a “respirator mask (Registration No. 10-2179117, hereinafter referred to as Patent Document 3)”.

In the case of the invention according to Patent Document 3, exhalation and inhalation are allowed to come in and out only through the nostril cover of the ventilation structure that can completely cover the nostril by closely fitting around the nostril and the intake and exhaust receiving part of the pocket structure provided inside the mask filter, so that the face and It prevents breathing of fine dust that is not filtered through the gaps between the masks, and at the same time expands the breathing capacity to make breathing comfortable, or exhaled air is directly discharged into the atmosphere through the exhaust passage provided in the filter, and the inhaled air is filtered after By allowing inhalation through the inhalation passage, deterioration of the function of the filter due to moisture in the exhaled breath is prevented, and the filter is provided with wavy wrinkles to greatly expand the breathing area of the mask.

The attaching unit 110 is disposed at a preset position. The preset position here is defined as a position where the user's nose and mouth can be partitioned in the inner space of the mask 1, and as shown in FIGS. 2 to 4 , it is preferable to be arranged in different positions according to preset positions.

In the case of the blocking plane portion 120, as shown in FIG. 2, it is configured to form a surface extending from the attaching portion 110 toward the face.

The blocking plane portion 120 forms an extension surface extending from the attaching portion 110 toward the other side of the air blocking unit 100 .

In addition, when the extended surface of the blocking plane portion 120 is formed, a predetermined area is formed in the inner space of the mask 1 .

The blocking plane portion 120 selectively divides the inner space of the mask 1 into predetermined areas to selectively limit the mutual exchange of air flowing in and out of the user's nose or the user's mouth.

Here, the predetermined area may be defined as an area divided into a space where the user's nose exists and a space where the user's mouth exists among the inner spaces of the mask 1 .

Since the expanded surface of the blocking plane part 120 blocks between the user's nose and the user's mouth, as shown in FIG. You cannot pass through space. Accordingly, when inhalation occurs through the user's nose, re-inhalation of exhalation can be blocked or minimized.

In addition, as shown in FIG. 5, one side of the air blocking unit 100 may be formed in a Velcro type that is selectively detachable from the inner surface 1a of the mask.

In addition, as shown in FIG. 9, the air blocking unit 100 can be partitioned by rolling a thick cloth to make the two spaces of the nose and mouth. In this case, the wire unit 200 and the wire cover unit 300 are unnecessary, and only Velcro or Velcro is required.

That is, the Velcro portion 130 is configured to attach and detach the air blocking unit 100 in a Velcro type.

In the case of the wire unit 200, as shown in FIG. 2, it is provided to the air blocking unit 100 and is selectively deformed so that the air blocking unit 100 is selectively brought into close contact with a predetermined position on the user's face. .

The wire unit 200 is present between the air blocking unit 100 and the face when the air blocking unit 100 divides a predetermined area, so that the air blocking unit 100 can be perfectly adhered to the face Thus, it performs the function of helping to limit the mutual exchange of air.

In addition, the wire unit 200 is a material such as a wire, a coated wire, a metal wire, or a rubber band for handicraft, and has a tensile strength that does not break even when pressure is applied or pulled in the longitudinal direction, and the object is not broken and deformed thinly against the pressure. It is desirable to have the property of being

In the case of the wire unit 200 of the mask system for preventing air mixing through selective blocking of the inner space of the mask according to the present invention, a rod part 210 and a rod fixing part 220 are included. . As shown in FIG. 2 and as described above, the rod part 210 and the rod fixing part 220 included in the wire unit 200 are made of rubber bands for handicrafts in consideration of production cost and user safety. Of course it can be replaced.
