Description

[0002] Mask capable of intake and exhalation air filtering,

The present invention relates to an air purifying mask having an exhaust purifying function, and more particularly, to an air purifying mask having an exhaust purifying function, and more particularly, Or prevent respiratory disease transmission due to respiration of suspect patients.

Particularly, according to the present invention, since the air intake portion into which the outside air is introduced into the mask is opened when the air intake is performed, and is closed when the air is exhausted, The present invention relates to an air cleaning mask capable of filtering an inspiration and an expiration so as to be prevented from being counted.

The easiest and most common way to block airborne contaminants, dust, or bacterial bacteria or viruses is to wear a mask.

In particular, Korea is exposed to yellow dust in the spring or fall season, causing many respiratory diseases such as allergies and asthma. In addition, the influenza A (H1N1) and the Middle East respiratory syndrome (MERS) The mask is becoming more important as it is known to be transmitted through the mouth.

Conventional masks generally consist of a body covering the nose and mouth of the wearer and a wear band for wearing the mask on the ear.

The conventional mask body as described above is manufactured by sewing and sewing mainly a simple surface or a fiber material, and there is a limit in blocking microbial bacteria and virus as well as fine dust and noxious gas contained in the air.

In view of such a problem, a dust mask or a respiratory mask or the like using a metal or synthetic resin filter is used so as to have a sufficient filtering and purifying function, but it has a disadvantage that it can only filter and purify the outside air and can not purify the wearer's exhalation .

In the case of the Middle East Respiratory Syndrome (MERS), which is popular in Korea recently, people who have taken care of a confirmed or suspected patient, patients and suspected patients can stay in the same place while they are having symptoms. A mask having an exhalation filtration and purifying function of a patient who has been confirmed or suspected is indispensable.

Korean Utility Model Publication No. 20-2016-0001206 " Dust mask "

In order to solve the above-mentioned problems, the present invention is to solve the above-mentioned problems by allowing various germs and minute foreign substances contained in the exhalation to be filtered and purified when sucking the outside air into the mask, And an air cleaning mask capable of filtering inhalation and exhalation that can prevent the transmission of respiratory diseases in advance.

Further, according to the present invention, it is possible to provide an air conditioner in which the outside air is introduced into the mask at the time of intake, and is closed at the time of exhaustion, and the gap of the intake portion, And an air cleaning mask capable of filtering the air and breathing that can prevent the air from being counted.

Particularly, it is an object of the present invention to provide an air cleaning mask capable of effectively filtering and purifying expiration and expiration by diffusing and discharging expiration that can be concentrated in a specific portion of the filter portion during exhausting.

In order to achieve the above object, an air cleaning mask capable of performing intake and exhaust filtering according to the present invention is characterized in that an air intake filter unit for filtering and introducing outside air is connected, And an expiration opening portion that is opened at the time of exhalation and closes at the time of exhalation.

The intake filter unit may include at least one intake filter for filtering the outside air, an intake filter assembly having the intake filter coupled to one side and the opposite side connected to an intake port formed on one side of the mask, At least one exhaust filter for filtering the exhalation, an exhaust filter combination in which the exhaust filter is coupled to one side and the opposite side is connected to an exhaust port formed on the other side of the mask.

Wherein the intake filter includes an intake air pre-filter for firstly filtering ambient air and an intake air filter for secondarily filtering ambient air firstly filtered by the intake air pre-filter, wherein the exhaust air filter includes an exhaust air filter Filter and an exhaust HEPA filter for secondarily filtering the primary filtered air in the exhaust pre-filter.

In addition, the inspiratory opening may include an intake manifold body formed with at least one intake hole through which the outside air filtered by the intake filter section passes, and an intake valve body that opens the intake hole at the time of exhalation and closes the intake hole at the time of exhalation, The venting opening may include an exhaust venting body having at least one vent hole through which the vent is passed to the vent filter portion side, and an exhaust valve body which opens the vent hole at the time of exhalation and closes the vent hole at the time of inspiration.

In addition, the intake valve body may include a valve cover formed by bending an edge toward the intake flow body side or by stepping.

It is preferable that the inspiration opening portion has a plate film adhesion layer formed along the edge of any one of the intake flow body and the intake hole or a plate film adhesion layer formed in a contact portion of the intake air flow body in close contact with the intake valve body .

In addition, the air cleaning mask capable of performing the intake and exhaust filters according to the present invention may further include a face-to-face contact member formed at least in part in contact with the face.

The present invention has the advantage of being able to filter and purify various kinds of germs and fine foreign substances contained in the exhalation even when the outside air is sucked into the inside of the mask as well as when the exhalation is discharged.

Thus, it is possible to prevent the transmission of respiratory diseases due to the respiration of a carrier or suspected patient.

Further, in the present invention, the air intake portion into which the outside air is introduced into the mask is opened when the air intake is performed, and the air intake portion, which may be generated during the exhausting operation, is closed.

Thereby, it is possible to prevent the expiration of the patient of the carrier or suspicious patient from being counted as the intake part which can not be filtered out.

In addition, there is an advantage that filtration and purification of exhalation can be efficiently performed by diffusing and discharging the exhalation that can be concentrated in a specific portion of the filter portion at the time of exhausting.

Accordingly, it is possible to improve reliability and competitiveness in the field of disease management, particularly in the mask and gas mask areas as well as in similar or related fields.
