Description

Mask {mask}

The present invention relates to a mask, and more particularly, to a water treatment structure in which foreign substances including yellow sand or fine dust remaining in the air flowing into a wearer's respiratory tract by the water film formed by the filtered water and the adsorption action of the stored filtered water. It is directed to a mask that is filtered through to enable the inhalation of clean air free of debris.

In general, a mask refers to an object covering the nose and mouth to prevent inhalation and scattering of germs and dust for health and hygiene, and is commonly referred to as 'cotton mask' because it is made of gauze, which is a coarse woven fabric made of single yarn. It is called '

Its origin was used as a concept to prevent colds in 1919 when the Spanish flu, or influenza, became popular.However, inhaling cold air directly weakened the resistance in the nasal cavity and oral cavity. Although it may be difficult to catch a cold, due to the nature of the plain weaving cotton fabric, the virus or bacteria smaller than the pores formed between the tissues of the cotton fabric pass through a cotton mask and many enter the human body through the nose or mouth, or conversely, those with respiratory diseases In the process of breathing, coughing, sneezing, etc., harmful particles such as viruses or bacteria discharged through the nose and mouth are scattered to the outside through the mask, so filtering of the particles using the mask is not effective. .

In addition, in Korea, due to the topography, small sands, loess or dust of deserts and ocher areas in the centers of Asian continents such as China and Mongolia, which float in the sky, are introduced to Korea in a large amount of western dust every year. In addition, it is frequently observed in the period of 3-6 days in March-May, and due to China's rapid industrialization, ultra-fine dust from many factories in China is flowing into the country in a western style.

The yellow sand is fine dust having a diameter of less than 10 μm, and in the case of ultra fine dust having a smaller diameter than the fine dust, the diameter is less than 25 μm, and it is impossible to filter fine dust or ultra fine dust with a general mask.

However, fine dust or ultra fine dust (hereinafter referred to as fine dust) penetrates to the deepest part of the respiratory tract when it enters the respiratory tract of the human body and penetrates into the blood vessels. WHO is known to be exposed to various diseases such as cardiovascular disease, skin disease, eye disease, as well as respiratory diseases such as asthma and bronchitis. There is a great interest in fine dust, such as designating black carbon as a primary carcinogen.

Accordingly, various measures to protect the human body by preventing the influx of fine dust as well as viruses and bacteria in health and hygiene have been known. The most common method is to use harmful masks such as viruses, bacteria and fine dust. To prevent particles from entering the body by filtering the particles.

However, conventional cotton masks are difficult to filter out harmful particles such as viruses, bacteria, and fine particles smaller than pores formed between the tissues of cotton fabrics because of the characteristics of flat cotton fabrics with sparse tissue. Developed to improve the lack of filtering performance, a fine dust mask made by mixing a nonwoven fabric and a filter is often called a yellow dust mask.

There have been various proposals regarding the yellow sand mask, but a typical conventional technology is as follows.

Hereinafter, a mask proposed as a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the external configuration of a mask having a water film filter structure proposed as a preferred embodiment in the present invention, Figure 2 is a cross-sectional configuration of the mask having a water film filter structure proposed as a preferred embodiment in the present invention 3 and 4 show the action state of the mask by the wearer's breath, respectively, FIG. 3 shows the action state according to inhalation, and FIG. 4 shows the action state according to exhalation.

Mask (1) proposed as a preferred embodiment in the present invention, as shown in Figures 1 to 4 is worn on the face of the wearer to cover the mask body 10 for covering the respirator including the mouth and nose with a ventilation structure It includes, the left and right sides of the mask body 10, the ear attachment portion 20 for attaching the wearer's mask body 10 to the wearer's ear, respectively, are formed.

Thus, the mask 1 is attached to both sides of the wearer's ear through the ear abutment 20, respectively, to cover the respirator including the mouth and nose formed on the wearer's face.

At this time, an inner pad edge of the mask main body 10 facing the wearer's face is provided with an adhesion pad 15 for elastically contacting the mask main body 10 and the wearer's face so that the outside air is provided with the mask main body 10. Prevents entry into the respiratory tract through gaps formed between the face and the face.

On the other hand, in the present invention, by providing a unique filtering structure for filtering foreign matter such as yellow dust or fine dust remaining in the air to be breathed in the mask body 10 to cover the breather of the wearer, the dust and fine dust Along with the stable filtration of foreign substances, it is possible to use repeatedly through the exchange of filtrate.

The mask body 10 includes an outer hood part 11 formed on an outer wall; An inner hood part 12 formed on the inner wall; And a suction pipe path 13 providing a communication path between the outer hood part 11 and the inner hood part 12.

Therefore, when the wearer inhales (inhales), the air introduced through the outer hood portion 11 flows into the wearer's respirator through the suction pipe 13 and the inner hood portion 12, and the wearer breathes out. (Exhalation) The air discharged from the respirator passes through the inner hood part 11, the suction pipe passage 13, and the outer hood part 12 sequentially and is discharged to the outside.

In this case, a pre-filter 16 is disposed in the outer hood part 12 to primaryly filter the foreign matter remaining in the air flowing into the suction pipe line 13 through the outer hood part 13.

The prefilter 16 may be made of ACF (Activated Carbon Fiber or Activated Carbon Felt).

The ACF is an adsorption material that develops micropores of molecular size through an activation process using carbonaceous material. ACF has 15 to 10 times larger adsorption capacity and 100 to 1,000 times faster adsorption rate than activated carbon used in general filters, which is excellent for exhaust gas removal.

Therefore, in the present invention, by using the ACF in the form of a non-woven fabric or fabric in combination with the electrostatic filter (Melt Blown) used in the existing mask, it can maximize the effect as a filter suitable for blocking yellow dust, fine dust and exhaust gas. .

Particularly, in the present invention, the foreign matter remaining in the air drawn into the inner hood part 11 through the suction pipe path 13 by being sucked in the outer hood part 12 in the suction pipe path 13 which is the movement path of inhalation and exhalation. The water treatment filter unit 30 is adsorbed through the stored filtered water.

The water treatment filter unit 30 according to the present embodiment includes a filtrate reservoir 31 mounted on the mask body 10 to store filtrate, and more preferably, absorbs the filtrate stored in the filtrate reservoir 31. It further comprises a water film forming filter 32 to form a water film in the suction pipe (13).

In addition, the water treatment filter unit 30 may be integrally mounted to the mask body 10 and configured to filter the air by water treatment. Preferably, the water treatment filter unit 30 communicates with the suction pipe passage 13 under the mask body 10. And to form an assembling slot 14 for inserting the filtered water reservoir 31, the filtered water reservoir 31 is entered and fixed in the assembly slot 14 to communicate with the suction pipe passage (13).

Further, the filtered water reservoir 31 may be a liquid medium including distilled water, or a gel-like adsorbent material that gradually evaporates to a liquid state and vaporizes while maintaining a state of being cured in a gel state.

In addition, the water film forming filter 32 forms a state in which the lower half of the filtered water reservoir 31 is infiltrated with filtered water, and the upper half is formed of a coil type exposed to the suction pipe passage 13, thereby forming the suction pipe passage 13. The air passing through is increased in contact frequency and contact time with the filtrate stored in the filtrate water storage tank 31 due to the interference with the coil-shaped water film forming filter 32, thereby achieving better adsorption of the remaining foreign matter.

Here, the coil-type water film forming filter 32 can be implemented with a solidified material such as plastic, but more preferably, it is composed of a nonwoven fabric having a water absorption function, and the water film itself with air interference. It is preferable to configure to perform a filtering function, which is also intended to be the scope of the present invention.

Therefore, the air inhaled through the outer hood part 12 by the breathing of the wearer wearing the mask 1 according to the present invention is introduced into the respirator through the suction pipe passage 13 and the inner hood part 11. In the process, the air passes through the water treatment filter unit 30 disposed in the suction pipe passage 13, and by adsorbing the foreign matter by the contact with the surface of the filtered water, and by the adsorption of the foreign matter by the contact with the coiled water film forming filter, A large amount of foreign matter including residual fine dust or yellow dust is removed.

Thus, a wearer wearing a mask according to the present invention can always inhale clean air from which foreign substances have been removed, and in particular, the water treatment filter unit 30 removes contaminated filtered water and fills new filtered water without any replacement or replacement. It has a feature that ensures continuous filtration through the mouth.

In addition, in the present invention, in implementing the mask 1, the bypass part 17 communicates with each other without passing through the intake pipe path 13 between the inner hood part 11 and the outer hood part 11. And the non-return valves 18 and 19 are disposed between the bypass portion 17 and the intake pipe passage 13 and the inner hood portion 12, respectively.

Here, the non-return valve 18 disposed on the bypass part 17 closes the bypass part 17 by air that is sucked into the inner hood part 12 through the outer hood part 11, and The non-return valve 18 disposed between the tracheal passage 13 and the inner hood portion 12 is disposed between the inner hood portion 12 and the intake pipe passage 13 by air exhausted by the inner hood portion 12. To close it.

Accordingly, in the intake process of the outside air by the wearer, as shown in FIG. 3, the bypass unit 17 is closed by the non-return valve 18, and the outer hood 11 and the inner hood 12 are connected to the intake pipe ( By communicating with each other through 13, the intake air through the outer hood part 11 is introduced into the inner hood part 12 through the intake pipe path 13 in which the water treatment filter part 30 is formed.

In the process of exhausting air by the wearer, the bypass unit 17 is opened as shown in FIG. 4, and the intake pipe path 13 is shielded from the internal hood unit 12 by the backflow prevention valve 19 to exhaust the air. The air to be discharged to the outside through the bypass unit 17 without passing through the intake pipe passage 13 in which the water treatment filter unit 30 is formed.

In this way, the water treatment filter part can be prevented from being contaminated by secretions such as saliva remaining in the breathing air during the exhausting process of the wearer's breathing air, which makes it possible to wear more hygienicly.
