Figure 3 shows a perspective view and an exploded perspective view of a breathing guide device according to an embodiment according to the present invention.

1 to 3, the breathing guide device 100 according to the present invention is mounted inside the filter unit 410 of the mask 400 for air filtration and used, and for exhaling the mask 400 ) The exhalation air supply member 110 disposed in front of the wearer's mouth, the exhalation flow path member 120 connected to the exhalation air supply member 110 and extending in the left and right direction of the filter unit 410, the exhalation flow path member 120 ) may include at least one exhalation exhaust member 130 in close contact with the inner circumferential surface of the filter unit 410 so that the exhalation is discharged through the inner circumferential surface of the filter unit 410 .

And, the present invention is provided in the breathing guide device 100, the exhalation exhaust member 130 of the breathing guide device 100 is provided in the filter unit 410 for air filtration in close contact with the inner peripheral surface, and the filter unit 410, It includes a mask for purifying air including a wearing member 430 to be worn on the wearer's ear or head, exhaled through the breathing guide device 100 and the filter unit 410, and breathing in through the filter unit A mask system capable of inhalation through an area in which the breathing guide device 100 is not mounted among ( 410 ) is provided.

Recently, the air quality is deteriorated due to fine dust or yellow dust, and the number of people wearing the mask 400 is increasing to protect health due to the emergence of a new virus. And, in order to more effectively block the fine particles in the air, the demand for a mask with a high dust blocking rate (eg, KF, N, KN) is increasing day by day, but as the dust blocking rate increases, the exhaust resistance of exhalation is also increased. tends to

The filter unit 410 constituting the mask 400 of the present invention may be composed of a MB (melt blown) filter or a combination of a nano filter and an additional nonwoven filter or a functional filter, and forms about 1 to 5 layers. and can be configured.

When the exhaled breath is not smoothly discharged during exhalation and the exhausted exhalation is re-inhaled while remaining inside the mask, there is a problem in that the air containing carbon dioxide or bad breath remaining in the exhalation is re-inhaled by the inhalation.

In addition, glasses users suffer from difficulties in securing vision as part of the exhalation exhaust is leaked through the gap between the mask and the skin, and moisture contained in the leaked exhalation is condensed on the spectacle lens due to the temperature difference between the outside air and the exhalation. In order to solve this problem, a mask equipped with an exhaust valve without a filter is also introduced so that the exhaled breath is discharged without exhaust resistance. Local laws prohibit the use of masks equipped with these exhaust valves.

According to the breathing guide device 100 and the mask system having the same according to the present invention, the mask 400 wearer exhales with the breathing guide device 100 mounted inside the filter unit 410 of the mask 400 for air purification. It can be configured to be exhausted so that exhalation and inhalation do not mix.

Specifically, the exhalation air supply member 110 is disposed in front of the mouth of the mask wearer, the exhalation flow path member 120 is connected to both sides of the exhalation air supply member 110, exhalation at each end of the exhalation air supply member 110 An exhaust member 130 is provided, and as shown in FIG. 3 , when the mask is worn, the exhalation air supply member 110 is disposed in front of the mask 400 wearer's mouth, and the exhalation exhaust member 130 is the wearer's Since it is in close contact with the filter unit 410 in a state where it is located in the concave pressed region on the outside of the molars between the cheekbones and the jawbone of the wearer, specifically, when the wearer of the mask 400 exhales, the carbon dioxide and the breath are the exhaled air. The member 110, via the exhalation passage member 120, the exhalation exhaust member 130 may be exhausted to the outside of the mask 400 by passing through the filter unit 410 corresponding to the inner peripheral surface region.

As shown in FIG. 1, in general, the filter part 410 of the mask extends up to between the cheekbones and the ears of the wearer, and is configured to cover the left and right jawbones below, so that the filter part 410 left and right ends A region The wearing member 430 is fixed to the ear and the like so as to be in close contact with the wearer's cheeks to prevent the inflow of external air and the leakage of exhaled air, and may be configured to have elasticity.

Therefore, the exhalation exhaust member 130 of the breathing guide device of the present invention is disposed in the concavely pressed area on the outside of the molar between the cheekbones and the jawbone of the wearer so as to be disposed just inside the area A where the filter unit and the skin are in close contact, It is possible to minimize pain or foreign body sensation due to interference between the member and the cheekbones or jawbone, and to minimize the inflow of external air without passing through the filter unit or leakage of exhaled air through the filter unit by preventing the filter unit from being lifted.

The exhalation air supply member 110 is at least one branch for transferring the air supplied through the air supply port 111 and the air supply port 111 disposed in front of the mask wearer's mouth to the exhalation flow path member (120) (113) may be provided.

The air supply port 111 of the exhalation air supply member 110 may be of a structure having a step on the outer rim so that the breathing guide device can be easily bitten with the teeth for a while with the wearer's teeth when the breathing guide device is first worn.

In addition, although not shown, the air inlet 111 is formed in a cone shape and may be configured in a form that can collect the exhaled breath as much as possible, but it may be configured in a form that is depressed inwardly or a form that is depressed after raising to minimize interference with the lips. may be

The air inlet 111 may be variously modified as long as the structure is arranged in front of the wearer's mouth in a state where the breathing guide device is mounted and the exhalation is supplied.

In addition, the exhalation air supply member 110 may be disposed in front of the mouth, may be configured to extend to the vicinity of the lips to be disposed in a contact state, may be configured in the form of a mouthpiece biting with the lips.

Here, the wearer may exhaust the exhalation by blowing the exhalation air supply member 110 disposed in front of the mouth. As described above, since the exhalation air supply member 110 is disposed in front of the wearer's mouth, most of the exhalation flows to the exhalation flow path member 120 connected to the exhalation air supply member 110 and through the exhalation exhaust member 130 . can be exhausted.

On the other hand, the exhalation exhaust member 130 is closely fixed to the inside of the mask filter unit 410 by various fixing means as will be described later, and the gap between the exhalation exhaust member 130 and the filter unit 410 is blocked. Minimize the phenomenon that the exhalation flowing through the exhalation air supply member 110 to the exhalation passage member 120 is discharged from the exhalation exhaust member 130 and flows into the inner space of the mask 400 . can do.

And, in the breathing guide device 100, the exhalation air supply member 110 is disposed in front of the wearer's mouth, and the exhalation passage member 120 is connected in the left and right opposite directions of the exhalation air supply member 110, the The exhalation exhaust member 130 may be configured to be in close contact with the inner surface of the filter unit 410 in the left and right regions spaced apart from the filter unit.

Therefore, the sum of the area of the exhaust port 131 of the pair of exhalation exhaust members 130 is greater than the area of the air supply port of the exhalation air supply member 110 to minimize the exhaust resistance during exhalation.

In addition, when the wearer exhales, not only carbon dioxide, but also moisture, saliva, etc. may be introduced into the exhalation passage member 120 through the exhalation air supply member 110 disposed in front of the mouth, and thus the exhalation exhaust member 130 . Since moisture is concentrated only on the filter unit 410 in the area corresponding to the exhaust port 131 of the wearer and contact with the wearer's mouth or skin near the mouth is prevented by the breathing guide device 100, discomfort to the wearer can be minimized.

Moisture or moisture continuously condensed on such a mask may accompany an odor, but the area where moisture is collected is the mask area between the mouth and nose, which is an intake area, so that the wearer can relieve moisture or odor.

As shown in Figure 3 (a), the exhalation channel member 120 and the exhalation exhaust member 130 is provided with a pair, respectively, can be connected in the left and right directions of the exhalation air supply member 110, respectively, and , The exhalation exhaust member 130 is configured in the form of a concave bowl (bowl), the exhalation passage member 120 may be connected to the side direction of the exhalation exhaust member (130).

As shown in the exploded perspective view of Figure 3 (b), the exhalation passage member 120 may have a structure that is mounted through the exhalation exhaust member (130).

That is, the breathing guide device may be configured to include one exhalation air supply member 110 , two exhalation passage members 120 and two exhalation exhaust members 130 , each of which may be assembled and mounted.

And, the exhalation channel member 120 may be mounted through the exhalation exhaust member 130 or the exhalation air supply member 110 during assembly.

The exhalation exhaust member 130 is configured to have a shape that decreases in thickness toward the direction opposite to the connection portion to which the exhalation flow path member 120 is connected, so that even when mounted in a mask, it is possible to minimize the occurrence of a region protruding or protruding to the outside.

Corresponding to the shape of the exhalation exhaust member 130, the inner end that penetrates or is inserted into the inner side of the exhalation air supply member 110 among both ends of the exhalation flow path member 120 is not limited in shape, but the exhalation exhaust member 130 ), the outer end penetrating inward may be inclinedly processed or cut to prevent interference with the inner circumferential surface of the filter unit 410 of the mask 400 .

In addition, the exhaust port 131 of the exhalation exhaust member 130 may be configured in a curved shape in consideration of the curve of the face so as to be in close contact with the inner circumferential surface of the filter unit 410 of the mask 400 .

And, as shown in Fig. 3 (a) and Fig. 3 (b), the exhalation air supply member 110, the exhalation flow path member 120 and the exhalation exhaust member 130 are each assembled in a separate configuration. Since the exhalation flow path member is mounted to be inserted or withdrawn through the exhalation exhaust member 130, the exhalation exhaust member 130 has a certain degree of sliding or position adjustment on the exhalation flow path member. It is possible.

Therefore, the interval between the exhalation exhaust member 130 and the exhalation air supply member 110 can be adjusted so that the exhalation exhaust member 130 is disposed immediately inside the A region of FIG. 1 even when the face shape or size is different. Position or connection angle can be adjusted. A description related thereto will be described later with reference to FIG. 7 .

Figure 3 (c) shows another embodiment of the breathing guide device of the present invention. As shown in FIG. 3( c ), the exhalation flow path member 120 has a ring shape in the circumferential direction for preventing separation or sealing when fastened to the exhalation air supply member 110 and the exhalation exhaust member 130 at both ends. of the projection 127 may be provided.

The protrusion may be formed integrally with the exhalation channel member 120 or separately made of a material such as rubber, resin, or silicone.

The exhalation channel member 120 may be made of a polyvinyl chloride (Polyvinyl Chloride, PVC) material, polypropylene (PP), polyethylene (PE) or low density polyethylene (LDPE) material.

In addition, the exhalation air supply member 110 or the exhalation exhaust member 130 is also polyvinyl chloride (Polyvinyl Chloride, PVC) material, polypropylene (Polypropylene, PP), polyethylene (polyethylene, PE) or low density polyethylene (Low density polyethylene) , LDPE) material.

In addition, the exhalation air supply member, the exhalation flow path member or the exhalation exhaust member may be made of a silicone material for the human body.

When polyvinyl chloride (PVC) is applied, the use of plasticizers known to contain environmental hormones for flexibility may be strictly restricted.

In addition, an adhesive material for attaching or sealing the filter unit 410 of the mask 400 to the edge of the exhaust port 131 of the exhalation exhaust member 130 may be coated.

The adhesive material is not for the purpose of inseparably bonding the exhaust port 131 and the filter unit, but the exhalation exhaust member 130 and the filter unit 410 of the mask 400 are in contact with the inner circumferential surface of the filter unit 410 to be maintained to some extent even when shaking. It is sufficient to have enough adhesive strength. The adhesive material may be a material such as double-sided tape or silicone in a gel or sol state.

4 is an example in which a plurality of fixing pins 133 are provided as fixing means for fixing the inner circumferential surface of the filter unit 410 of the mask 400 to the edge of the exhaust port 131 of the exhalation exhaust member 130. shows

In the example shown in FIG. 3 and the like, an example in which an adhesive material is added along the edge of the exhaust port 131 of the exhalation exhaust member 130 is illustrated, but the fixing means of the embodiment shown in FIG. 4 is the exhalation exhaust member 130 . It may be a plurality of fixing pins 133 provided integrally with the exhaust port 131 of the mask 400 and protruding in a direction toward the filter unit 410 of the mask 400 .

Here, the fixing pin 133 may pass through the filter unit 410 to closely fix the filter unit 410 to the exhalation exhaust member 130 . Here, the number, size, and shape of the fixing pins 133 can be freely manufactured. For example, as shown in FIG. 4 , the fixing pins 133 are integrally configured, and the filter unit 410 is formed. One end may have a pointed shape to facilitate penetration.

And, although not shown in FIG. 4 , the fixing pin 133 has an end in a wedge or arrow shape, so that the fixing pin easily penetrates the filter unit, but may be configured in various shapes to provide a locking function in the separation direction.

In addition, when the exhalation exhaust member 130 is made of a PVC material or LDPE, etc., when the thickness of the fixing pin 133 integrally configured with the exhalation exhaust member 130 is sufficiently thin to have a certain degree of flexibility It is possible to secure a level of rigidity that can penetrate the filter unit without being easily broken.

And, as shown in Figure 4 (b), the exhaust port filter 200 for exhalation filtration exhausted through the exhaust port 131 of the exhalation exhaust member 130 may be further provided.

The exhaust port filter 200 may be fixed to the exhaust port 131 in the same manner as in the case where the fixing pin is provided or an adhesive material is provided, as in the method of being fixed to the filter unit 410 of the mask 400 . .

The exhaust filter 200 may also be composed of a MB (melt blown) filter or a combination of a nano filter and an additional nonwoven filter or a functional filter, and the mask ( 400) is the same as the filter unit.

In addition, when the exhaust port filter 200 is added to the breathing guide device 100 according to the present invention, in addition to the essential effect of additionally filtering the exhalation, the exhaust port filter 200 has a small area and a simple structure compared to the mask. Therefore, if several sheets (eg, 2 to 10) of the exhaust filter 200 are provided together with the breathing guide device 100 as a package, the mask wearer can only use the exhaust filter 200 that is wet or contaminated with the moisture of the exhalation. Since it is possible to increase the usable time of a mask having a relatively large area by replacing it, an economic effect of minimizing the cost associated with the mask can be obtained as a result.

The exhaust port filter 200 may have a shape and size corresponding to the exhaust port 131 of the exhalation exhaust member 130 of the breathing guide device because the flow path of the inhalation is not interfered, and is provided to additionally filter only the exhalation, and the exhaust port filter The size of (200) is preferably configured to have a slightly larger size than the exhalation exhaust member 130 to facilitate the mounting of the fixing pin.

When the mask system user is infected with an infectious disease, the filter unit 200 can help the wearer's breathing and has the effect of mitigating the spread of the disease to nearby people.

The filter unit 200 is worn on the wearer's face and has an effect of effectively filtering out fine dust or yellow dust introduced from the outside during breathing, while the filter unit removes pathogens contained in droplet particles when the wearer coughs or sneezes. (410) By blocking the discharge to the outside, it is possible to promote public hygiene.

In addition, the exhaust filter 200 may be detachably mounted to the breathing guide device 100, and when only the exhaust filter 200 in which the moisture or contaminants of the exhaled breath is concentrated is replaced again, the mask replacement cycle is increased cost can be reduced.

The area of the exhaust filter 200 is preferably configured to be larger than the area of the exhalation exhaust member 130 of the breathing guide device 100, and is penetrated by a fixing pin when the breathing guide device 100 is mounted to the mask It may be closely fixed to the inner circumferential surface of the filter unit 410 of 400 .

In addition, since the exhaust filter 200 can be mounted on almost any mask other than a mask for filtering fine dust together with a breathing guide device, if there is concern about the spread of pathogens by the exhalation of a person infected with a virus disease or a suspected infection, the general mask also has a disease. It can be worn and used for the purpose of diffusion.

And, by a method of mounting the exhaust port filter 200 to the exhalation exhaust member 130 or the exhaust port 131 constituting the breathing guide device 100, a mask on the edge of the exhaust port 131 of the exhalation exhaust member 130 ( 400) In addition to the method of coating the inner peripheral surface of the filter unit 410 with an adhesive material for attachment or sealing, the edge of the exhaust port filter 200, that is, on the part in contact with the edge of the exhaust port 131 of the exhalation exhaust member 130 A method in which an adhesive material is coated may also be used. In this case, the exhaust filter 200 may be provided in the form of a sticker to improve usability.

Figure 5 shows a wearing state of the mask system provided with a breathing guide device according to another embodiment of the present invention.

In addition to the method in which the above-described fixing pin 133 passes through the filter unit to fix the exhaust port 131 to the filter unit, a method for fixing using a separate fixing member 300 is also possible.

As shown in FIG. 5 , the fixing member 300 may further include a fixing member 300 having a fine fixing hole through which the fixing pin 133 passed through the filter part 410 and exposed to the front of the filter part passes. The fixing member 300 may be made of an elastic material such as silicone or rubber, and may have a ring shape with an open center, so that it may correspond to the shape of the exhaust port 131 of the exhalation exhaust member 130 . Therefore, the filter unit 410 can be firmly fixed between the exhalation exhaust member 130 and the fixing member 300, and by the through hole generated when the mask is penetrated by the fixing pin 133. The outflow of exhalation can be minimized.

In addition, since the fixing member 300 can seal the fixing pin 133 protruding through the filter unit 410 from the outside, the skin is not punctured by the fixing pin 133 and the breathing guide device ( 100) can improve the convenience of use.

In this case, in order to prevent the fixing pin 133 from protruding further to the outside of the fixing member 300 , the through hole provided in the fixing member 300 may be configured in the form of a through hole instead of a hole.
