The face mask according to an embodiment of the present invention includes a front portion 10 covering the nose and mouth, and an upper sealing portion 20 connected to an upper side of the front portion and sealing an upper side of the front portion. The front portion 10 and the upper sealing portion 20 may be made of a separate material, it may be made of the same material integrally without a special section. On the other hand, it may further include a lower sealing portion 30 is connected to the lower side of the front portion 10, sealing the lower portion of the front portion. The lower sealing part 30 may be made of a separate material different from the front part 10, and may be made of a single material with the same material without a special compartment. Both end portions of the face mask are provided with a hook portion 40 for wearing. The shape of the hook portion is shown as a structure to be worn on the user's ear, but is not limited thereto, and may be a band form for wearing on the user's head.

The front portion 10 is provided with a separation member 50 for separating the nasal fluid space and the mouth fluid space. Separation member 50 is horizontally coupled to the inner central portion of the front portion 10, made of a membrane, and is located between the nose and mouth to separate the nasal fluid space and the mouth fluid space.

The front part 10 may be divided into the front part 11 of the nasal fluid space and the front part 12 of the mouth fluid space by the separating member 50, and the front part 11 and the mouth of the nasal fluid space. The front part 12 of the fluid space may or may not be made of the same material. The front part 12 of the nasal fluid space is a place where external air enters when inhaled through the nose, and has a filter function on all or part of the front part 12 of the nasal fluid space, thereby causing a source of contamination such as fine dust of the outside air. Can be filtered. Preferably it may be provided with a hepa filter, it may be composed of a hepa filter within the H11 to H13 grade range.

5 is a view for explaining the breathability of the separating member 50, Figure 6 is a view for explaining the breathability of the front portion 12 of the mouth fluid space.

The front part 10 may be breathable, but may have different air permeability between the front part 11 of the nasal fluid space and the front part 12 of the mouth fluid space. Meanwhile, the air permeability expressed in the present specification means air permeability, and can be quantitatively measured according to the ISO 9237 standard.

The facial mask according to an embodiment of the present invention is separated from the nasal fluid space and the mouth fluid space, it is possible to prevent inhalation of the air exhaled by the mouth again to the nose when inhaled through the nose can lead to healthy breathing.

On the other hand, the user may be able to perform a healthy breath inhaled by the nose and exhaled through the mouth completely, but sometimes also exhaled some or all of the nose. In this case, due to the front filter function of the nasal fluid space, the air exhaled by the nose is not rapidly discharged to the outside, so that the air is expelled again due to resorption or a gap is generated between the mask and the face, and the gap is forcibly discharged. This can cause problems such as the introduction of external pollutants.

In order to prevent this, the separating member 50 may satisfy the following Equation 1.

<Equation 1>

0 ≤ A <B

Here, A means the air permeability of the separating member 50 in the direction of the nasal fluid space in the mouth fluid space, B means the air permeability of the separating member 50 in the direction of the mouth fluid space in the nasal fluid space, 0 is non- Means breathable. Breathability can be quantified by measuring to the ISO 9237 standard.

That is, the separating member 50 may be smoothly ventilated from the nasal fluid space in the direction of the mouth fluid space (B) so that the air exhaled from the nose may be quickly discharged into the mouth fluid space through the separating member 50. . However, if the air flows easily from the mouth fluid space in the opposite direction to the nasal fluid space (A), air exhaled by the mouth may enter the nasal fluid space through the separating member and may be re-intake into the nose. It is better to design it as non-breathable or smaller than B. Although not limited, B may be 1.5 times or more than A, and specifically, it is preferable to be large in the range of 2 times to 100 times.

On the other hand, the front part 12 of the mouth fluid space breathability is good in the front part air permeability (D) from the mouth fluid space to the outside direction so that the air can be smoothly discharged to the outside when the mouth is exhaled. On the contrary, the breathability of the front part 12 of the mouth fluid space from the outside to the mouth fluid space is non-breathable or at least greater than the breathability C of the front part 12 of the mouth fluid space from the outside to the mouth fluid space. good. Although not limited, D may be 1.5 times or more than C, and specifically, it is preferably larger than 2 times to 100 times.

In particular, in order to induce healthy breathing, the front part 12 of the mouth fluid space may satisfy the following equation (2).

<Equation 2>

0 ≤ C <B

Here, B means the breathability of the separating member from the nasal fluid space to the mouth fluid space direction, C means the front of the mouth fluid space from the outside to the mouth fluid space direction, and 0 means non-breathability. C should be designed to be non-breathable or smaller than B. Although not limited, B may be 1.5 times or more than A, and specifically, it is preferable to be large in the range of 2 times to 100 times.

That is, the front part 12 of the mouth fluid space is made non-breathable to the air permeability (C) in the direction of the mouth fluid space from the outside, or more than the breathability (B) of the separating member 50 from the nasal fluid space to the mouth fluid space direction By making it small, it is possible to prevent or reduce the inflow of outside air through the front portion 12 of the mouth fluid space when the user inhales the mouth, thereby inducing the user to inhale into the nose. In addition, after the fresh air is introduced into the nasal fluid space through the front portion 11 of the nasal fluid space having a filter function so as to perform a filtration function of contaminants upon inhalation into the mouth, it passes through the separating member 50. (B direction in FIG. 5) may be delivered to the mouth fluid space to allow for intake.

As described above, the means for controlling the breathability of the separating member 50, the front portion 12 of the mouth fluid space is not limited. Preferably, as shown in Figures 7 to 10, it may be configured to vary the breathability of the separating member 50 in accordance with the direction. Although the separating member 50 is illustrated, the front portion 12 of the mouth fluid space may have the same structure and principle, and is not limited. That is, as shown in Figure 7, the separating member 50 corresponds to the front portion 12, A breathability corresponds to C breathability, B breathability corresponds to D breathability. The front portion 12 also includes a stretchable layer 51 and a non-stretchable support layer 52. Hereinafter, the separating member 50 will be described by way of example.

Specifically, the separating member 50 may include a stretchable layer 51 having increased porosity when stretched and a non-stretchable support layer 52 supporting the stretchable layer. With this structure, the separating member 50 has elasticity that stretches in the direction of the mouth fluid space and decreases again, and the non-stretchable support layer 52 prevents the stretchable layer 51 from stretching in the nasal fluid space direction. It is inelastic. Here, the elasticity and non-elasticity may be an absolute concept or may be a relative concept in the relationship between the elastic layer and the non-elastic support layer.

The stretchable layer 51 is a layer that substantially determines the amount of air permeation, and as shown in FIG. 8, the stretchable fibers can be woven or knitted at high density. Although not shown, the elastic fibers may be aligned in one direction, or the elastic fibers may be randomly spun and distributed using electrospinning or the like. The stretchable layer 51 may be in the form of a stretchable porous membrane that is stretched and shrinks again or in the form of a fabric, and may be in the form of a stretchable nonwoven fabric. The air permeability (breathability) of the state before stretching can be controlled by the texture of the fabric, the porosity, and the like.

Relatively, the non-stretchable support layer 52 is a support layer that inhibits the stretch of the stretchable layer 51 and may be structured at a lower density than the stretchable layer 51. As shown, non-stretchable fibers can be woven or knitted to a lower density and higher porosity relative to the stretch layer. Although not shown, the non-stretchable fibers may be aligned in one direction.

The stretchable layer 51 and the non-stretchable support layer 52 may be stacked, and may be bonded in whole or in part. Preferably, in order to increase the stretching displacement of the stretchable layer to increase the porosity and to increase the porosity and to further increase the air permeability, it is preferable to partially join the stretchable layer. The bonding method may be physically bonded or chemically bonded using an adhesive or the like.

The stretchable layer 51 may be made of stretchable fibers. Examples of the stretchable fibers include twisted fibers of elastic polyurethane resins, rubber yarns processed with natural rubber, and synthetic fiber filaments such as nylon, polyester, and acrylic. It may be a twisted yarn which is processed and wrinkled, or a conjugate thread obtained by crimping by having a component having different shrinkage ratios in one filament.

The non-stretchable support layer 52 may be made of spun yarn, non-stretchable fibers, or the like. As the non-stretchable fibers, natural fibers, regenerated fibers, or synthetic fibers may be used alone or in combination.

Referring to FIG. 9, the elastic layer expands into the mouth fluid space due to the flow of air from the nasal fluid space to the mouth fluid space to increase porosity (S), thereby improving air permeability and providing a smooth flow of air. 9 and 10 show only a part of the fabric structure of the stretchable layer 51 for convenience of explanation and understanding.

On the contrary, when the air flows from the mouth fluid space to the nasal fluid space, the non-stretchable support layer 52 is supported to prevent the elastic layer 51 from extending into the nasal fluid space, thereby preventing air permeability.

Similarly, the front portion 12 of the mouth fluid space includes a stretchable layer that increases porosity when stretched and a non-stretch support layer that supports the stretchable layer, wherein the front portion 12 of the mouth fluid space includes: It may be stretched outwards and contracted again, and may be inelastic in the direction of the mouth fluid space.

11 and 12 are face masks according to another embodiment of the present invention, wherein the upper sealing portion 20 may have a bellows structure 21 for size adjustment. Since the face structure and size of the user are different, the sealing may be effectively performed by adjusting the mask size through the bellows structure 21.

In addition, the upper sealing part may further include a close contact part 22, so that the upper sealing part may be deformed and adhered according to the shape of a face such as a nose. The close contact portion may be easily deformed and may be made of an inelastic material such as metal to maintain the deformed shape. Alternatively, the upper sealing portion may be adhered to the face by using an adhesive material such as an adhesive tape and using adhesiveness.

Figure 13 is a face mask according to another embodiment of the present invention, the front portion 12 of the mouth fluid space may be provided with at least one or more one-way valve 60, for more smooth air discharge during exhalation by mouth. have. The one-way valve 60 is not limited as long as it is a valve structure that opens in the outer direction and closes in the inner direction. As an example, the structure and details of the present applicant's Patent Publication No. 10-1914642 can be used, and various one-way valve structures can be adopted.
