Description

The present invention relates to a mask that prevents the transmission of bacteria and viruses through the air.

In this age of COVID-19, people are strongly urged to wear masks, which are said to be effective against COVID-19, to prevent the spread of infection. However, conventional masks are not designed to protect against viruses like COVID-19, and because of their structure, they cannot 100% block the penetration of the virus, so people are also strongly urged to maintain social distance.

The problems that this invention aims to solve are: 100% prevention of bacteria and viruses penetrating the mask; increasing the chances of capturing bacteria and viruses in the air that passes through the mask without causing breathing difficulties; wearing a mask improves the air environment; and it is convenient to use.

The present invention aims to solve these problems by using a material on the surface of the mask that is impermeable to air and bacteria and viruses contained in the air, by providing a new intermediate air passage inside the mask, by taking in inhaled air from above the mask and exhaling air from below the mask, by providing a new measurement card for measuring exhaled air, and by making the mask foldable.

The present invention provides a foldable isolation mask as a means for solving the problem;
It consists of:

The outer isolation layer is composed of an outer cover, which is an impermeable material that cannot be penetrated by air or bacteria or viruses contained in the air, and has a surface and an air treatment surface. The surface can be processed to capture bacteria and viruses, so that the air environment around the mask is improved, which has a positive effect on both others and yourself;

The air treatment surface is equipped with an adsorption function that can capture bacteria and viruses, and can adsorb harmful substances such as bacteria and viruses in the air flowing through the mask;

The inner isolation layer is composed of a filter, an air valve, a nose wire, a cart bag, a filter bag, and an inner cover;

The inner cover is made of an impermeable material that cannot be penetrated by air or bacteria and viruses contained in the air, has a mouth surface and an air treatment surface, and has an intake port and an exhalation port in the center. The mouth surface is soft and has a sweat absorbing function to be gentle on the face, and the air treatment surface has an adsorption function to capture bacteria and viruses, and can adsorb harmful substances such as bacteria and viruses in the air flowing into the mask;

The inlet and the outlet are provided for the passage of respiratory air, the inlet being on top and the outlet being on the bottom, and their size or number being determined according to the ease of breathing;

The filter can filter out bacteria and viruses in the air.

The filter bag is attached to the mouth surface of the intake and exhaust ports to allow easy insertion and replacement of the filter.

The air valve is a one-way passage for air to pass through the inlet and the outlet of the mask. Both the inlet and the outlet are one-way. When inhaling, the inlet is open and the outlet is closed, and when exhaling, the outlet is open and the inlet is closed;

The nose wire is attached to the center of the inner cover, allowing it to fit and stay in place according to the shape of your nose;

The cart bag is attached to the mouth surface and holds the measurement card.

Becoming a passageway;

The intermediate air layer is an air flow layer formed between the outer isolation layer and the inner isolation layer, and is open in the vertical direction to allow air flow, but is closed on both sides by the merging of the outer isolation layer and the inner isolation layer on the left and right, preventing air flow;

Ear straps are attached to either side of the mask to keep the mask in place on the face;

Since the dimension between both sides of the outer isolation layer is larger than that of the inner isolation layer, when the mask is unfolded, the space between the inner isolation layer and the outer isolation layer expands and an intermediate air layer appears, and when the mask is folded, the intermediate air layer disappears.

The measurement cart contains thin flakes of exhaust gas measurement material that can be newly placed on the mask for self-testing;

100% prevention of bacteria and viruses from penetrating the mask allows for safe close-range conversations. Air is drawn in from the top and exhausted from the bottom, eliminating the risk of cross-infection between people, so people don't have to worry about being in a movie theater or a dome. Convenient, as it can be opened when in use and folded when not in use. The mask comes equipped with a measurement card that measures the breath, allowing the wearer to easily self-test, providing countless benefits.

1 is a diagram showing an embodiment of a foldable isolating mask 1 of the present invention. Figure A shows the mask in an unfolded state, and Figure B shows the mask in a folded state. The foldable isolating mask 1 is composed of an outer isolating layer 2, an inner isolating layer 3, and ear straps 7.

Fig. 2 is a diagram showing an example of the configuration of one embodiment of the foldable isolation mask of the present invention. Fig. A is a plan view of the outer cover 23 of the outer isolation layer 2: the outer cover 23 is made of an air-impermeable material, so that air and bacteria and viruses in the air cannot penetrate the outer isolation layer 2; the outer cover 23 has a surface 21 and an air treatment surface 22: the surface 21 can 100% block droplets, so that close-range conversations can be made with peace of mind; the air treatment surface 22 has an adsorption function like an adsorbent, so it can process the air passing through the mask and adsorb harmful substances such as bacteria and viruses;

2B is a plan view of the inner cover 36 of the inner isolation layer 3. The inner cover 36 is made of an air-impermeable material and is shaped so that there is no gap between the mask and the face when the mask is worn. It has an intake port 33 and an exhalation port 34 in the center to allow respiratory air to pass through the inner cover 36;

The intake port 33 is for passing inhaled air, and may be a single hole or multiple holes as long as it allows easy inhalation. Since it is desired to take in air from the top of the mask, the intake port 33 is located above the exhalation port 34;

The exhalation port 34 is for passing exhaled air, and may be one or more holes as long as it is easy to exhale. Since it is desired to blow out the exhaled air from the bottom of the mask, the position of the intake port 34 is set lower than the exhalation port 33;

The inner cover 36 has an air treatment surface 31 and a mouth surface 32. The air treatment surface 31 has an adsorption function like an adsorbent, so it can process the air passing through the mask and adsorb harmful substances such as bacteria and viruses; the mouth surface 32 is soft and gentle on the face, and has the function of absorbing sweat;

2C is a plan view of the inner cover 36 with the filter bag 35 and filter 5 attached. The filter 5 filters harmful substances such as bacteria and viruses in the air, and since it is installed at the exhalation port 33 and the intake port 34, it may also be installed at the air inlet of the mask; the filter bag 35 is for easily attaching or replacing the filter 5.

3 is a diagram showing an example of the configuration of one embodiment of the foldable isolation mask 1 of the present invention. Figure A shows the outer cover 23 of the flat body being bonded at the outer intermediate bonding line 17 to become the outer isolation layer 2 of the three-dimensional body; Figure B shows the inner isolation layer 3 of the three-dimensional body being bonded at the inner intermediate bonding line 18, in which the filter 5 and the exhaust blocking valve 8 can be seen; Figure C shows the folded state of the foldable isolation mask 1 in which the outer isolation layer 2 and the inner isolation layer 3 are bonded at both sides at the inner and outer bonding lines 16 and the ear loops 7 are attached; Figure D is a front view of the foldable isolation mask 1 in an open state.

3E is a view showing the mouth surface of the foldable isolation mask 1 in an open state. Since the lateral size of the outer isolation layer 2 is larger than that of the inner isolation layer 3, when both sides of the mask 1 are opened, an intermediate air layer 40 is formed between the outer isolation layer 2 and the inner isolation layer 3, and the exhalation outlet 13 and the inhalation inlet 14 are visible.

4 is a diagram showing the mechanism of one embodiment of the foldable isolating mask 1 of the present invention. Figure A shows the front view of the foldable isolating mask 1 in a worn state, and cutaway views B, C and D are created to explain the state change of the mask 1 during breathing and its mechanism:

Fig. 4B shows a cross-sectional view of the mask 1 shown in Fig. 4A when the difference between the air pressure outside the mask 1 and the air pressure around the mouth is stationary, and includes an outer isolation layer 2, an inner isolation layer 3, and an exhaust blocking valve 8. In order to prevent exhaled air from coming out from the top, while allowing inhaled air to be taken in from the top, one end of the exhaust blocking valve 8 is fixed to the inner isolation layer 3 as shown in the figure, and the other end is free to move up and down by force;

The forces that move the exhaust check valve 8 include respiratory force, restoring force and friction force, among which only exhalation moves upward and the others move downward. Alternatively, the respiratory force and the restoring force occur simultaneously and in opposite directions, while the friction force occurs after the free end of the exhaust check valve 8 comes into contact with the external isolation layer 2. Ultimately, the resultant force of the upward force and the downward force determines the direction that moves the exhaust check valve 8.

Fig. 4C is a cutaway view of the mask 1 during exhalation. At first, the exhaust valve 8 is pushed upward by the resultant force, but when the free end comes into contact with the outer isolation layer 2, the resultant force becomes zero and the movement stops, and the exhaled air cannot go out upward.

FIG. 4D is a cross-sectional view of the mask 1 in the state of inhalation. The exhaust valve 8 is constantly pushed downward by the combined force, allowing the inhaled air to be taken in from both above and below.

5 is a diagram showing an example of the configuration of one embodiment of the foldable isolating mask 1 with separate breathing passages of the present invention. The foldable isolating mask 1 with separate breathing passages has the features and functions of the foldable isolating mask 1 described above, and also has a new function of separating the breathing passages. However, the mechanism of the foldable isolating mask 1 with separate breathing passages allows exhaled air to be released only downwards, eliminating the need for the exhaust valve 8.

2C is a plan view of the mouth surface 32 showing the position where the air valve 6 is attached.

6 is a diagram showing an additional configuration example of one embodiment of the foldable isolation mask 1 with separate breathing passage according to the present invention. Figure A shows the outer cover 23 of the flat body being joined at the outer intermediate joining line 17 to become the outer isolation layer 2 of the three-dimensional body; Figure B shows the inner isolation layer 3 of the three-dimensional body being joined at the inner intermediate joining line 18, where the air valve 6 attached to the exhalation port 34 under the air treatment surface 31 can be seen; Figure C shows the folded state of the foldable isolation mask 1, where the outer isolation layer 2 and the inner isolation layer 3 are joined at both sides at the inner and outer joining lines 16 and the ear loops 7 are attached; Figure D is a front view showing the foldable isolation mask 1 in an open state.

FIG. 6E shows the mouth side of the foldable isolation mask with separate breathing passage 1 in an open state, and the air valve 6 attached to the inlet 33 above the mouth side 32 can be seen; since the lateral size of the outer isolation layer 2 is larger than that of the inner isolation layer 3, when both sides of the mask 1 are opened, an intermediate air layer 40 is formed between the outer isolation layer 2 and the inner isolation layer 3, and the exhalation outlet 13 and the inhalation inlet 14 can be seen.

7 is a diagram showing the structure of one embodiment of the foldable isolating mask 1 with separate breathing passages of the present invention. FIG. 7A is a front view of the foldable isolating mask 1 with separate breathing passages in a worn state;

Connected to the isolation layer 3, the middle air layer 40 is isolated into two spaces, an upper one and an lower one. As shown in the figure, the air valve 6 is attached to the inner isolation layer 3, the upper one is fixed and the lower one is free, and can be moved by force; the forces that move the air valve 6 include breathing force and restoration force, and since the breathing force is stronger, the air valve 6 always moves in the direction of breathing.

Fig. 7C is a cross-sectional view of the mask 1 when exhaling. The exhaled air is blown out from the mouth toward the mouth surface 32, and the air valve 6 moves accordingly, so that the upper air intake 33 is closed and the exhaled air cannot come out, while the lower air intake 34 is opened wide, and the exhaled air is discharged from the exhalation outlet 13 via the exhalation port 34;

Fig. 7D is a cutaway view of the mask 1 when inhaling. Inhaled air is drawn from the mouth surface 32 toward the mouth, and the air valve 6 moves accordingly, so that the lower exhalation port 34 is closed and air cannot enter, while the upper intake port 33 is opened wide, and the inhaled air enters from the intake port 14 and is inhaled through the intake port 33;

8 is a diagram showing an example of the configuration of one embodiment of the foldable isolation mask 1 with an exhaust measurement function of the present invention. The foldable isolation mask 1 with an exhaled breath measurement function has the features and functions of the above-mentioned foldable isolation mask 1 with separate breathing passage, and further has a new exhaled breath measurement function.

The mask measurement card 12 is an air measurement agent in the form of a thin sheet. The measurement agent varies depending on the measurement target, but it is the same whether or not the measurement target is included in the exhaled breath when it is incorporated in the isolation mask 1.

The cart bag 11 is attached to the mask 1 and holds the measurement card 12 therein.

The foldable isolation mask of the present invention can contribute not only to the medical field, but also to maintaining economic activity, protecting social stability, and ensuring peace of mind in people's lives, and therefore has great industrial applicability.
