Description

Technical Field

[0001] The present invention relates to a mask that prevents the transmission of bacteria and viruses through the air.

Background Art

[0002] In this era when the novel coronavirus infection is raging, in order to prevent the spread of infection, wearing a mask that is said to be effective against the novel coronavirus is strongly required. However, conventional masks are not intended to deal with viruses such as the novel coronavirus, and even if one wants to deal with them, it is impossible to completely block the penetration of the virus structurally, so it is also strongly required to maintain social distance.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The problems to be solved by the present invention are as follows: being able to completely block the penetration of bacteria and viruses through the mask, increasing the chance of collecting bacteria and viruses in the air passing through the mask without causing dyspnea, improving the air environment by wearing the mask, and being convenient to use.

Means for Solving the Problems

[0004] The means for solving the problems of the present invention include using a material that does not allow air or bacteria and viruses contained in the air to pass through on the mask surface, newly providing an intermediate air passage in the mask, taking in the air inhaled from above the mask and exhaling the exhaled air from below the mask, newly providing a measurement card for measuring exhalation, and being foldable.

[0005] The present invention provides a foldable isolation mask as a means for solving the problems; TIFF0007710643000001.tif8160ーd, composed of ear straps:

[0006] The outer isolation layer is composed of an outer cover. The outer cover is a non-breathable material that air or bacteria and viruses contained in the air cannot penetrate, and it has a surface and an air treatment surface. If the surface is processed so that it can collect bacteria and viruses, the air environment around the mask will be improved, which will have a positive effect on both others and oneself;

[0007] The air treatment surface is equipped with an adsorption function capable of collecting bacteria and viruses, and can adsorb harmful substances such as bacteria and viruses in the air flowing into the mask;

[0008] The inner isolation layer is composed of a filter, an air valve, a nose wire, a cart-containing bag, a filter bag, and an inner cover;

[0009] The inner cover is a non-breathable material that air or bacteria and viruses contained in the air cannot penetrate, and it has a mouthpiece surface and an air treatment surface, and is equipped with an air inlet and an air outlet at the central part. The mouthpiece surface has a soft function of absorbing sweat and is gentle on the face. The air treatment surface is equipped with an adsorption function capable of collecting bacteria and viruses, and can adsorb harmful substances such as bacteria and viruses in the air flowing into the mask;

[0010] The air inlet and the air outlet are provided for passing respiratory air. The air inlet is above and the air outlet is below, and their sizes or numbers depend on the ease of breathing;

[0011] The filter can filter bacteria and viruses contained in the air

[0012] The filter bag is attached to the mouthpiece surface of the air inlet and the air outlet, and is for facilitating the insertion and replacement of the filter

[0013] The air valve allows air to pass through only one side of the air inlet and the air outlet of the mask. Both the air inlet and the air outlet are one-way. When inhaling, the air inlet is open and the air outlet is closed. When exhaling, the air outlet is open and the air inlet is closed;

[0014] The nose wire is attached above the center of the inner cover and can fit and be fixed to the shape of the nose;

[0015] The cart-containing bag is attached to the mouth surface and is for inserting the measurement card.

[0016] TIFF0007710643000002.tif becomes the 13159 passage;

[0017] The intermediate air layer is an air flow layer formed between the outer isolation layer and the inner isolation layer. It is open in the vertical direction for air flow, but in the horizontal direction, it is closed by the merger of the outer isolation layer and the inner isolation layer on both sides, and air cannot flow through. It is an intermediate air layer;

[0018] The ear loops are attached to both sides of the mask to keep the mask in place on the face;

[0019] 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, a space is formed between the inner isolation layer and the outer isolation layer, and the intermediate air layer appears. When the mask is folded, the intermediate air layer disappears, so it can be folded like this.

[0020] The measurement card is an exhaust measurement agent in the form of a thin sheet of measurement agent, and it is for newly installing on the mask for self-checking;

Advantages of the Invention

[0021] It can completely prevent bacteria and viruses from penetrating through the mask, so that people can have close conversations with confidence. By inhaling from above and exhaling from below, the risk of cross-infection between people is eliminated. Therefore, people don't have to worry whether they are in a movie theater or in a dome. It is convenient because it can be opened when in use and folded when not in use. By equipping the mask with a measurement card for measuring exhalation, the wearer can easily conduct self-checks, so there are countless advantages.

Mode for Carrying Out the Invention

Examples

[0023] FIG. 1 is a diagram showing an embodiment of the foldable isolation mask 1 of the present invention. FIG. A shows the unfolded state, and FIG. B shows the folded state. The foldable isolation mask 1 is composed of an external isolation layer 2, an internal isolation layer 3, and ear loops 7.

[0024] FIG. 2 is a diagram showing a configuration example of an embodiment of the foldable isolation mask of the present invention. FIG. A is a schematic plan view of the outer cover 23 of the external isolation layer 2: the outer cover 23 is composed of an outer cover 23 made of an airtight material, and air, bacteria, and viruses in the air cannot penetrate the external isolation layer 2; the outer cover 23 has a surface 21 and an air treatment surface 22: the surface 21 can reject 100% of droplets, so you can feel at ease even when having a short-distance conversation; since the air treatment surface 22 has an adsorption function like an adsorbent, it can treat the air passing through the mask and adsorb harmful substances such as bacteria and viruses.

[0025] Figure B in Fig. 2 is a schematic plan view of the inner cover 36 of the internal isolation layer 3. The inner cover 36 is made of an airtight material and is shaped so that there is no gap between it and the face when the mask is worn. In order to allow breathing air to pass through the inner cover 36, an air intake port 33 and an exhalation port 34 are provided in the central part;

[0026] The air intake port 33 is for allowing air intake. As long as air can be easily taken in, it can be a single hole or multiple holes. And since it is desired to take in air from above the mask, the position of the air intake port 33 is installed above the exhalation port 34;

[0027] The exhalation port 34 is for allowing exhalation. As long as exhalation can be easily done, it can be a single hole or multiple holes. And since it is desired to exhale from below the mask, the position of the exhalation port 34 is installed below the air intake port 33;

[0028] The inner cover 36 has an air treatment surface 31 and a mouth area surface 32: The air treatment surface 31 has an adsorption function like an adsorbent, so it can treat the air passing through the mask and adsorb harmful substances such as bacteria and viruses; The mouth area surface 32 is soft and gentle on the face and has the function of absorbing sweat;

[0029] Figure C in Fig. 2 is a schematic plan view of the inner cover 36 with the filter bag 35 and the filter 5 attached. The filter 5 is for filtering harmful substances such as bacteria and viruses in the air. Besides being installed at the exhalation port 33 and the air intake port 34, it can also be installed at the air inlet of the mask, etc.; The filter bag 35 is for easily mounting or replacing the filter 5.

[0030] Figure 3 is a diagram showing a configuration example of an embodiment of the foldable isolation mask 1 of the present invention. Figure A shows the state where the outer cover 23 of the flat body becomes the external isolation layer 2 of the three-dimensional body by being joined at the outer intermediate connection line 17; Figure B shows the state of the internal isolation layer 3 of the three-dimensional body by being joined at the inner intermediate connection line 18, and the filter 5 and the exhaust prevention valve 8 can be seen; Figure C shows the folded state of the foldable isolation mask 1 where the external isolation layer 2 and the internal isolation layer 3 are joined by the inner and outer connection lines 16 on both lateral sides and the ear loop 7 is attached; Figure D is a diagram showing the front view of the open state of the foldable isolation mask 1.

[0031] Figure E in Figure 3 is a diagram showing the mouth area surface of the open state of the foldable isolation mask 1. Since the lateral size of the external isolation layer 2 is larger than that of the internal isolation layer 3, when both sides of the mask 1 are widened, an intermediate air layer 40 is formed between the external isolation layer 2 and the internal isolation layer 3, and the exhalation outlet 13 and the inhalation inlet 14 can be seen.

[0032] Figure 4 is a diagram showing the mechanism of an embodiment of the foldable isolation mask 1 of the present invention. Figure A is a front schematic view of the foldable isolation mask 1 in the worn state. In order to explain the state change of the mask 1 and its mechanism during breathing, the cross-sectional schematic diagrams in Figures B, C, and D were created:

[0033] Figure B in Figure 4 is a cross-sectional schematic view of the mask 1 in the static state in Figure A, showing the difference between the external air pressure and the mouth area pressure of the mask 1, with the external isolation layer 2, the internal isolation layer 3, and the exhaust prevention valve 8. Since exhalation cannot come out from above while inhalation can be taken in from above, one end of the exhaust prevention valve 8 is fixed to the internal isolation layer 3 as shown in the figure, and the other end is free and can move up and down by force;

[0034] The forces that move the exhaust prevention valve 8 include the breathing force, the restoring force to the original state, and the frictional force. Only exhalation is in the upward direction and the others are in the downward direction. Or the breathing force and the restoring force to the original state occur simultaneously and are forces in opposite directions, while the frictional force occurs after the free end of the exhaust prevention valve 8 comes into contact with the external isolation layer 2. Eventually, the resultant force of the upward force and the downward force determines the direction and moves the exhaust prevention valve 8.

[0035] Figure C in Figure 4 is a schematic cross-sectional view of the inhalation mask 1 during exhalation. Initially, the exhaust prevention valve 8 is pushed upward by the resultant force and rises. However, after the free end comes into contact with the outer isolation layer 2, the resultant force becomes zero and the movement stops, indicating that exhaled air cannot escape upward;

[0036] Figure D in Figure 4 is a schematic cross-sectional view of the inhalation mask 1 during inhalation. The exhaust prevention valve 8 is constantly pushed downward by the resultant force, allowing inhalation from both above and below;

[0037] Figure 5 is a diagram showing a configuration example of an embodiment of the respiratory passage separation type foldable isolation mask 1 of the present invention. The respiratory passage separation type foldable isolation mask 1 has the characteristics and functions of the foldable isolation mask 1 described above, and in addition, a new respiratory passage separation function is added. However, in the mechanism of the respiratory passage separation type foldable isolation mask 1, since exhaled air can only escape downward, the exhaust prevention valve 8 is no longer necessary.

[0038] It is a schematic plan view of TIFF0007710643000003.tif13159; Figure C in Figure 2 is a schematic plan view of the mouth surface 32 showing the mounting position of the air valve 6.

[0039] Figure 6 is a diagram additionally showing a configuration example of an embodiment of the respiratory passage separation type foldable isolation mask 1 of the present invention. Figure A shows the state in which the outer cover 23 of the flat body becomes the outer isolation layer 2 of the three-dimensional body by being joined at the outer intermediate joining line 17; Figure B shows the state of the inner isolation layer 3 of the three-dimensional body by being joined at the inner intermediate joining line 18, and the air valve 6 attached to the exhalation port 34 below the air treatment surface 31 can be seen; Figure C shows the state of the folded isolation mask 1 in the folded state where the outer isolation layer 2 and the inner isolation layer 3 are joined by the inner and outer joining lines 16 on both lateral sides and the ear loop 7 is attached; Figure D is a front view showing the open state of the foldable isolation mask 1.

[0040] Figure E in Fig. 6 is a view showing the mouthpiece surface of the foldable isolation mask 1 with separated breathing passages in an open state, and the air valve 6 attached to the air intake port 33 above the mouthpiece surface 32 can be seen; since the lateral size of the external isolation layer 2 is larger than that of the internal isolation layer 3, when both sides of the mask 1 are spread, an intermediate air layer 40 is formed between the external isolation layer 2 and the internal isolation layer 3, and the exhalation outlet 13 and the air intake and inlet 14 can be seen.

[0041] Fig. 7 is a view showing the mechanism of an embodiment of the foldable isolation mask 1 with separated breathing passages of the present invention. Fig. A is a front schematic view of the foldable isolation mask 1 with separated breathing passages in a worn state;

[0042] TIFF0007710643000004.tif7159 is connected to the isolation layer 3 to separate the intermediate air layer 40 into two upper and lower spaces. As shown in the figure, the air valve 6 is attached to the internal isolation layer 3, with the upper part fixed and the lower part free and able to move by force; the forces for moving the air valve 6 include the breathing air force and the restoring force to the original state, and since the breathing air force is stronger, the air valve 6 always moves according to the breathing direction.

[0043] Fig. C in Fig. 7 is a cross-sectional schematic view of the mask 1 in Fig. A during exhalation. Exhalation blows out from the mouth towards the mouthpiece surface 32, and the air valve 6 also moves accordingly. Therefore, the upper air intake port 33 is closed and exhalation cannot come out, while the lower exhalation port 34 is widely opened, and exhalation is discharged from the exhalation outlet 13 through the exhalation port 34;

[0044] Fig. D in Fig. 7 is a cross-sectional schematic view of the mask 1 in Fig. A during inhalation. Inhalation is drawn from the mouthpiece surface 32 towards the mouth, and the air valve 6 also moves accordingly. Therefore, the lower exhalation port 34 is closed and air cannot enter, while the upper air intake port 33 is widely opened, and inhalation enters from the air intake and inlet 14 and is sucked in through the air intake port 33;

[0045] FIG. 8 is a diagram showing a configuration example of an embodiment of the foldable isolation mask 1 having the exhaust measurement function of the present invention. The foldable isolation mask 1 having the exhalation measurement function has the features and functions of the above-described foldable isolation mask 1 of the respiratory passage separation type, and further adds a new exhalation measurement function.

[0046] The measurement card 12 for the mask is an air measuring agent formed into a thin sheet. Although the measuring agent varies depending on the measurement target, it is the same regarding whether the measurement target is included in the exhaled air when incorporated in the isolation mask 1.

[0047] The bag 11 with a cart is for attaching to the mask 1 and inserting the measurement card 12.
