Recently, many people suffer from fine dust more harmful to the human body than yellow dust.

In general, fine dust refers to the dust of a fairly fine particles having a particle size of 10㎛ or less, and has a great effect when inhaled by the human body. Fine dust is a problem because it causes serious diseases such as heart attack, asthma, bronchitis, pneumonia and lung cancer.

Accordingly, long-term exposure to fine dust may cause respiratory and cardiovascular diseases, and mortality has also been reported to increase significantly.

Therefore, although the performance of filtering the dust varies according to the density of the fiber through which the air passes, there is a limit in preventing the fine dust that is lethal to the human body even if the tissue of the fiber is dense.

The mask body 10 has an inlet 15 through which air is introduced. The inlet port 15 is equipped with an inlet air filter 17. The inlet air filter 17 is formed in a mesh shape to allow air to pass therethrough, and filters the air introduced into the inlet 15. In addition, the inlet air filter 17 may be mounted to the inlet 15 so that replacement is possible.

In addition, the mask body 10 is formed with an outlet 19 through which air introduced into the inlet 15 is discharged toward the wearer's nose.

In the mask body 10, chambers 21a and 21b having a predetermined volume space are formed between the inlet 15 and the outlet 19. These chambers 21a and 21b also provide thermal insulation in winter.

Meanwhile, the chambers 21a and 21b of the mask body 10 are divided into two chambers, for example, the first chamber 21a and the second chamber 21b, based on the center line of the nose. For example, the bent portion 25 is formed along the center line of the nose of the mask body 10, and the chamber of the mask body 10 is based on the bent portion 25 and has a first chamber 21a and a second chamber. It is divided into 21b. Accordingly, the mask body 10 can be folded along the bent portion 25, and thus the mask body 10 can be folded and conveniently carried. Here, the bent portion 25 is preferably made of a silicon material which is harmless to the human body and excellent in elasticity.

Hereinafter, since the respective components accommodated in the first chamber 21a and the second chamber 21b are the same, each component in the first chamber 21a is illustrated in FIGS. 3 and 4 for convenience of description. do.

The pocket 30 has a hollow pocket shape, and may be formed of a synthetic resin material having excellent breathability and waterproofness.

In addition, the pocket 30 is provided corresponding to the quantity of the chambers 21a and 21b. In this embodiment, as the chamber is divided into the first chamber 21a and the second chamber 21b, the pockets 30 are also provided in pairs. Each pocket 30 is airtight and is accommodated in the first chamber 21a and the second chamber 21b of the mask body 10, respectively.

The inside of the pocket 30 is divided into a water reservoir 31 for storing water and an air reservoir 41 for passing the water reservoir 31 and the filtered air to stay and flow toward the outlet 19. It is.

The water reservoir 31 and the air reservoir 41 are disposed up and down inside the pocket 30.

One side of the water storage unit 31 is equipped with a drain plug 33 for draining the water of the water storage unit 31. The drain plug 33 maintains airtightness so that water in the water storage part 31 does not leak, and is penetrated through the pocket 30 and the mask body 10.

On the other hand, the drain plug 33 is provided with a plug filter 35 for contacting water in the water storage unit 31 and filtering water stored in the water storage unit 31.

The air retention portion 41 is partitioned off by a plurality of partitions 43. The plurality of partition walls 43 are arranged to be inclined upward toward the discharge port 19 in a zigzag form at intervals between the air retention portions 41. Thereby, the air retention part 41 is provided with the zigzag-shaped air flow path 45 by the some partition 43. As shown in FIG. In this way, as the plurality of partition walls 43 are inclined upwardly in a zigzag form toward the outlet 19, even if the wearer's face is inclined below a certain inclination angle while the wearer wears the mask 1, The water stored in the water storage unit 31 is prevented from being discharged to the outlet 19 through the air flow path 45.

On the other hand, the drain hole 47 is formed in the lower end of each partition 43. The drain hole 47 naturally drains the water introduced into the air flow path 45 to the water storage part 31 according to the inclination of the partition wall 43.

In addition, the drain hole 47 is provided with a plate-shaped partition wall flap 49. The partition flap 49 is rotatably provided by being blocked by the partition 43 so as to open and close the drain hole 47.

When the water in the water storage unit 31 flows into the air flow path 45, the water flows along the partition wall 43 from the upper side to the lower side of the partition wall 43, and the partition flap 49 is the weight of the water. By rotating by opening the drain hole 47, the water is drained to the water storage unit (31). On the contrary, when the pocket 30 is inclined, the partition flap 49 is rotated so that the water in the water storage part 31 does not flow into the air flow path 45 through the drain hole 47, and the drain hole 47 is provided. To close it. Thus, by providing the partition flap 49, it is possible to prevent the water in the storage unit 31 flows back to the air flow path 45 through the drain hole 47 of each partition 43. .

The air inlet tube 50 has a hollow pipe shape and guides the air introduced into the inlet 15 to the water storage unit 31.

The air inlet tube 50 is airtightly connected to the inlet 15 of the mask body 10, extends downwardly toward the water reservoir 31, and then extends to be accommodated in the water reservoir 31. It is. That is, the air inlet tube 50 is accommodated in the chambers 21a and 21b of the mask body 10, and one end thereof is connected to the inlet 15, and the other end thereof is the water reservoir 31 of the pocket 30. It is immersed in and accommodated.

On the other hand, a plurality of nozzle holes 51 are formed in the air inflow tube 50 located in the water storage portion 31 of the pocket 30. The outside air flowing into the inlet 15 and flowing along the air inlet tube 50 is dispersed and discharged into the water of the water storage unit 31 through the plurality of nozzle holes 51 to discharge the water and the air. This can be increased to improve the removal efficiency of pollutants contained in the air.

In addition, the feed inlet tube 50 located in the water reservoir 31 is surrounded by an air filter 55 for the tube.

The air filter 55 for the tube is made in the form of a mesh to allow the air to pass through, by bursting the air bubbles formed by the air discharged into the water through the air inlet tube 50, to differentiate the air into the water As a result, contaminants can be filtered while flowing through the water to the upper region of the water.

Here, the outer diameter of the tube air filter 55 is preferably smaller than the outer diameter of the drain plug 33. Thereby, as the drain plug 33 is removed, the tube air filter 55 can be replaced easily. In addition, instead of the air filter 55 for a tube, the same effect as the air filter 55 for a tube can also be obtained as the circumference | surroundings of the air inflow tube 50 are wrapped with a cotton or cloth, and these materials are soaked in water. have.

In addition, the water filter mask 1 according to an embodiment of the present invention includes a valve 60 in which the outlet 19 is opened and closed by inhalation of the wearer. The valve 60 includes a valve body 61 and a valve flap 63.

The valve body 61 has a hollow sleeve shape and is connected to the air retention portion 41 of the pocket 30 and the discharge port 19 of the mask body 10 with airtightness.

The valve flap 63 has a plate shape and is coupled to one side of the valve body 61 by a blockage so as to be rotatable with respect to the valve body 61. The valve flap 63 rotates by the inhalation of the wearer to open the outlet 19, and closes the outlet 19 when the inhalation of the wearer does not work. Therefore, the valve flap 63 has a check valve function to prevent the air from flowing backward from the outlet port 19 toward the air reservoir 41.

Moreover, the air filter 65 for valves is provided in the inner periphery of the valve main body 61. As shown in FIG. The air filter 65 for the valve is formed in a mesh form to allow air to pass therethrough, and is primarily filtered through the water storage unit 31 to filter the air introduced into the valve 60 through the air reservoir 41 again. do. In this way, by adding the valve air filter 65, it is possible to maximize the filtering power of the air flowing into the nose.

Here, reference numeral 27, which is not described, is provided to the mask body 10, and is a exhalation exhaust port through which the exhalation of the wearer is discharged. Exhalation exhaust port 27 is made of a mesh form to allow air to pass through. Although not shown in the exhalation exhaust port 27, a plate-shaped check valve may be provided. At this time, the check valve and the exhalation exhaust port 27 allows the air exhaled by the wearer to be discharged to the outside of the mask body 10, but the outside air is inside the mask body 10 through the check valve and the exhalation exhaust port 27. That is, a function of preventing the wearer from flowing in the direction of the face part may be performed.

By this configuration, in a state in which the wearer wears the water filter mask 1 according to an embodiment of the present invention and looks at the front while standing on the ground, the water storage part 31 of the pocket 30 is located below, The air reservoir 41 is located above the water reservoir 31.

As the wearer breathes through the nose, a negative pressure is generated inside the pocket 30, and as shown by arrows in FIG. 2, contaminated air containing fine dust and harmful gases is introduced into the inlet 15 and the air inflow. At the same time as it flows into the water storage part 31 of the pocket 30 via the tube 50, the valve flap 63 of the valve 60 is opened, and the outlet 19 of the mask main body 10 is opened.

On the other hand, the outside contaminated air introduced into the water storage unit 31 is discharged into the water of the water storage unit 31 through the plurality of nozzle holes 51 of the air inlet tube 50 is discharged, contaminated air After contaminants such as fine dust and harmful gas contained in the reaction react with the water and are adsorbed and removed, the purified air flows into the air reservoir 41 of the pocket 30. At this time, the air bubbles formed by the air discharged into the water through the air inlet tube 50 is burst by the air filter 55 for the tube and micronized into the water, flows through the water to the upper region of the water In addition, the filtration rate of contaminants can be maximized.

The purified air introduced into the air reservoir 41 through the water reservoir 31 flows along the air flow path 45, passes through the air filter 65 for the valve, and the remaining contaminants are filtered again. In addition, the valve 60 is sucked into the wearer's nose through the outlet 19 of the mask body 10.

The exhalation exhaled by the wearer through the nose or mouth is discharged to the outside through the exhalation exhaust port 27 formed in the mask body 10.

As a result, the fine dust and harmful gas contained in the air are purged through the pocket 30 which functions as a water filter, so that the wearer of the water filter mask 1 according to an embodiment of the present invention can drink the purified air. Will be.

On the other hand, even if the wearer's face is inclined to less than a certain inclination angle in the state in which the wearer wears the mask 1, the water is prevented by the plurality of partitions 43 arranged to be inclined upwardly in a zigzag form toward the outlet 19. Water stored in the storage unit 31 is prevented from being discharged to the outlet 19 through the air flow path (45).

As described above, according to the present invention, the fine dust and harmful gas contained in the air are filtered through the water by inhalation of the wearer, and the purified air can be sucked in by wearing the mask.

In the above, embodiments of the present invention have been described with reference to the accompanying drawings, but those skilled in the art to which the present invention pertains may realize the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
