Description

Functional mask {Functional mask}

The present invention relates to a functional mask, which wraps around the mouth and nose and is comfortable to wear, and is capable of inducing comfortable breathing by separating inhalation and exhaustion due to inhalation and exhalation.

Although high-performance masks currently on the market have a relatively good blocking rate of fine dust, paradoxically, it is difficult to breathe and cannot be reused repeatedly.

In addition, due to the spread of the Corona 19 virus, masks that can block not only fine dust, but also droplets and viruses are being developed, and in modern society, masks are positioned as necessities of life.

First, the standard of masks on the market is that F80 can filter out more than 80% of fine particles with an average size of 0.6㎛, and 'KF94' and 'KF99' mean that they filter 94% and 99% of particles with an average size of 0.4㎛, respectively. And, there was a problem that the higher the number, the more difficult it was to breathe due to the resistance of breathing.

In addition, the current mask was not able to provide a comfortable feeling of use due to moisture condensing on the inner surface of the mask when used for a long time due to inhalation and exhalation by simply wrapping the area around the nose and mouth with a cloth pad method.

In addition, due to moisture condensing on the inside, it was impossible to re-wear due to bacterial propagation and odor, and the static electricity filtration efficiency to filter out fine particles was lowered.

Therefore, there is a need to develop a mask that can be comfortably worn while wrapping around the nose and mouth, and can induce smooth breathing.

The filter 201 is applicable to any filter capable of purifying air, such as a HEPA filter, an activated carbon filter, and a fine dust blocking filter that blocks fine dust, foreign substances, and splashes, and products other than those mentioned in this specification are also applicable. This is possible.

The saddle unit 300 includes an intake hole 301 through which air purified due to intake air passes, and an exhaust valve 302 for discharging exhaled air to the outside. That is, when the user wearing the body 400 breathes in, the outside air passes through the filter 201 and the purified air that has passed through the filter 201 passes through the intake hole 301 and flows into the interior of the body 400 . do. And when breathing is exhaled, the exhaust valve 302 is opened and the exhaled air is discharged to the outside. At this time, the exhaust valve 302 is preferably manufactured as a check valve that is opened only during exhalation.

The body 400 is in contact so that one surface covers the face of the person, that is, the nose and mouth. At this time, an insertion hole 410 into which the saddle part 300 is fitted is further formed on one side of the main body 400 , and in this case, the insertion hole 410 preferably has an open shape on both sides. In addition, the body 400 is preferably made of a flexible and soft material, and may be made of, for example, silicon or the like.

In addition, a flow channel S through which the purified air passing through the intake hole 301 moves is further formed in the body 400 . The purified air moving through the flow channel S provides the advantage of inducing smooth nasal breathing by moving the purified air to the upper end of the main body 400, that is, to a portion adjacent to the nose.

2 to 3 , the saddle part 300 is integrated with the filter assembly 200 and is inserted into the insertion hole 410, and preferably, the saddle part 300 and the body 400 are mutually attached and detached. have This has the advantage that the main body 400 can be easily removed and washed periodically, and only the main body 400 can be removed and replaced when replacement is required due to damage or aging.

Conversely, the saddle part 300 has an embodiment that is integral with the body 400 . At this time, only the filter assembly 200 is detachable from the saddle part 300 , and when replacement of the filter assembly 200 is required, only the filter assembly 200 can be detached and replaced. When the body 400 and the saddle part 300 are integrated, there is an advantage in that the shape of the body 400 made of a soft material can be maintained.
