[First Embodiment]
Hereinafter, embodiments of the present invention will be described with reference to the drawings and the like.
1A and 1B are views showing the mask 1A according to the first embodiment, where FIG. 1A is a front view, FIG. 1B is an IB-IB end view, and FIG. 1C is an IC-IC arrow view.
The mask 1A according to the first embodiment has a mask main body 2A that covers the face such as the nose and mouth of the mask wearer, and ear hook portions 3 attached to both end edges of the mask main body 2A.
In the following description, in the mask body 2A, the innermost (innermost layer) surface that comes into contact with the face when the mask is worn is referred to as the "inner surface", and the outermost (outermost) surface that comes into contact with the outside air on the opposite side of the "inner surface". The surface of the outer layer) is called the "outer surface".

The mask body 2A has a four-layer structure in which a protective filter 23, an elastic filter 24, a collection filter 22, and a conductive filter 21 are arranged in this order from the outside to the inside when the mask is worn. Each of these filters 21 to 24 is formed in a sheet shape having substantially the same size, and is arranged adjacent to each other. Further, another filter similar to the protection filter 23 may be provided inside the conductive filter 21.
The above filter name is expressed by the function of the filter, and the order of arranging the filters is arbitrary. However, it is desirable that the collection filter 22 and the conductive filter 21 are arranged adjacent to each other. Further, the filter may be a filter having multiple functions from the viewpoint of cost and the like, for example, by integrating the protection filter 23 and the elastic filter 24 into an integrated structure.

The ear hook 3 is fixed to the left and right edge portions of the mask body 2A by welding or the like. The ear hook portion 3 is formed in a string shape, for example, with elongated rubber or the like, and fixes the mask body 2A at the position of the face. Further, the ear hook portion 3 can be formed of the same fiber material as the mask body 2A, and in this case, a fiber material having elasticity is preferable.
The ear hook portion 3 may be a type that hangs on the ear or a type that circulates the head.

Next, each member constituting the mask main body 2A will be described.
[Conductive filter]
The conductive filter 21 is conductive, has excellent elasticity and breathability, and for example, knitted fabric, woven fabric, non-woven fabric and the like can be used. As the conductive filter 21, for example, a fiber material in which a metal material such as silver, copper, nickel or the like or a semiconductor material such as graphite or silicon carbide is attached to or contained in the fiber can be used, and electric resistance can be used. It is selected in consideration of conductivity and the like.

The conductive filter 21 is arranged on the inner layer side when the mask is worn. Further, since the conductive filter 21 is electrically connected to the piezoelectric member 4 described later, the voltage generated by the piezoelectric member 4 can be applied over almost the entire surface of the conductive filter 21.
The conductive filter 21 can inactivate micropathogens adhering to the mask body 2A by utilizing the voltage generated by the piezoelectric effect of the piezoelectric member 4.
As a result, by using the conductive filter 21, the antibacterial performance and the like are less likely to vary as compared with the case of using a fiber containing an antibacterial agent in which metal ions are supported on solid particles such as zeolite. There are merits.

The effect of inactivating micropathogens according to the present embodiment (hereinafter referred to as inactivating effect) includes an antibacterial effect of suppressing the growth of micropathogens, a sterilizing effect of reducing the number of micropathogens, and a complete elimination of micropathogens. It includes at least one of a sterilizing effect that kills micropathogens, a bactericidal effect that kills micropathogens, a disinfecting effect that kills or eliminates micropathogens to reduce the risk of infection, and an anti-infective effect that eliminates the infectivity of micropathogens.

[Collecting filter]
The collection filter 22 is a member that collects minute pathogen dust, and is arranged adjacent to the outside (middle side) of the conductive filter 21 when the mask is worn.
The fiber used for the collection filter 22 is preferably a fiber having a filter function and easily charged, and examples thereof include non-woven fabrics such as polypropylene fiber and polyester fiber. For this non-woven fabric, for example, it is preferable to use ultrafine fibers produced by the melt blow method.

The collection filter 22 is charged during the manufacturing process. The collection filter 22 that has been charged in this way enables adsorption of minute pathogens by static electricity. Examples of the method used for the charging process include a known method of injecting ions such as corona discharge, triboelectric charging, and pulse voltage to charge the battery. The charged collection filter 21 can adsorb micropathogens by the charged static electricity.
In general, the electric charge of the charged collection filter is discharged with the passage of time. On the other hand, the collection filter 22 according to the present embodiment can be recharged by the voltage charged by the conductive filter 21, so that the charging effect can be maintained.

[Protective filter]
The protective filter 23 has a function of protecting the conductive filter 21, the collection filter 22, and the elastic filter 24 from rubbing and abrasion during use, in addition to improving the shape retention and reinforcing properties of the mask body 2A.
As the protective filter 23, one having good breathability and water absorption, for example, a non-woven fabric of polyester fiber can be used. The protective filter 23 is arranged on the outermost layer when the mask is worn.
When the protective filter 23 is arranged on the inner surface, it is preferable to select a material that does not cause discomfort when touching the face, has less fluffing, and is soft to the touch.

[Elastic filter]
The elastic filter 24 is a thin plate-like body that can be elastically deformed by external stress. As the elastic filter 24, a porous one can be used, and can be formed of, for example, metal, resin, paper or the like.
The elastic filter 24 may have a mesh shape.

The elastic filter 24 is arranged in an intermediate layer inside the protective filter 23 of the outermost layer. The piezoelectric member 4 can exert a greater effect by coupling with the elastic filter 24.
When a mesh-like filter made of thin metal or resin is used as the protective filter 23, the piezoelectric member 4 may be coupled to the inside of the protective filter 23 to integrate the protective filter 23 and the elastic filter 24.

[Piezoelectric member]
When the piezoelectric member 4 is bent due to an external stress, the piezoelectric effect (piezo effect) generates positive and negative charges on the upper and lower surfaces polarized in the thickness direction according to the stress. Since this charge is generated according to the magnitude of the stress, the larger the stress on the piezoelectric member 4, the larger the potential difference (voltage) is generated. Therefore, the piezoelectric member 4 can be formed by joining the above-mentioned elastic filter 24 in addition to being composed of a single piece of piezoelectric material or a combination of a plurality of piezoelectric materials, so that the deflection can be increased even if the same external force is applied, and a large potential difference ( Voltage) can be obtained.

The piezoelectric member 4 is a member made of a piezoelectric material that is formed in a thin plate shape and has flexibility. The piezoelectric member 4 is obtained by mixing piezoelectric particles in, for example, piezoelectric ceramics such as lead zirconate titanate (PZT), piezoelectric resins such as polyvinylidene fluoride (PVDF), piezoelectric single crystals such as quartz and crystal, and rubber materials. It can be formed by using a thinned piezoelectric material such as a piezoelectric rubber or a piezoelectric mineral.

As shown in FIG. 1B, the piezoelectric member 4 is provided on the surface of the elastic filter 24 of the mask body 2A, but it can also be provided inside the elastic filter 24.
Then, the mask 1A can generate a voltage on the surface of the conductive filter 21 electrically connected to the piezoelectric member 4 by utilizing the piezoelectric effect of the piezoelectric member 4.

The piezoelectric member 4 has a unimorph structure bonded to the surface of the elastic filter 24 made of the above-mentioned porous metal thin plate or the like (FIG. 1 (B)), and a potential difference larger than that of the unimorph structure can be obtained. A bimorph structure in which two piezoelectric members 4 are joined can be formed.
Further, an elastic filter 24 may be sandwiched between the bimorph structures in order to increase the strength and the life. As a result, the piezoelectric member 4 can generate a large potential difference (voltage) even with bending due to a slight stress.

[Nose fit member]
The nose fit member 5 is provided on the outermost member when the mask is worn, and is arranged along the upper edge portion of the protective filter 23 in the present embodiment. The nose-fitting member 5 is made of a deformable metal material so that the shape can be changed along the contour of the nose muscle of the mask wearer.
The nose-fitting member 5 can prevent a gap from being formed between the face and the mask body 2A when the mask is worn, and can prevent the invasion of micropathogens through the gap.

When the air flow caused by the conversation or breathing of the mask wearer occurs, the mask body 2A of the first embodiment expands or contracts along the air flow. At this time, since stress is also applied to the mask body 2A according to the flow of air, when the mask is worn, the piezoelectric member 4 provided on the mask body 2A applies a voltage due to the piezoelectric effect every time conversation or breathing is performed. By generating a voltage, a voltage can be generated on the surface of the conductive filter 21 electrically connected to the piezoelectric member 4, and the voltage can be used to inactivate the micropathogens adhering to the mask body 2A. can.

As described above, according to the first embodiment, there are the following effects.
(1) In the mask 1A of the present embodiment, a voltage is applied to the surface of the mask body 2A because the piezoelectric member 4 having a power generation function provided in the mask body 2A bends due to the movement and breathing of the mask wearer's face. Can occur. Therefore, the mask 1A can inactivate the micropathogen attached to the mask body 2A for a long period of time. Therefore, according to the mask 1A, the inactivating effect is less likely to deteriorate over time.

(2) The mask 1A of the present embodiment is capable of applying a voltage generated from the piezoelectric member 4 over almost the entire surface of the mask body 2A by a collection filter 22 electrically connected to the piezoelectric member 4. It is configured in. Therefore, as compared with the conventional mask using an antibacterial agent, the inactivating effect can be uniformly applied on the surface of the mask body 2A without variation.
Further, since the collection filter 22 according to the present embodiment can be recharged by the voltage charged by the conductive filter 21, the charging effect can be maintained.

[Second Embodiment]
2A and 2B are views showing the mask 1B according to the second embodiment, where FIG. 2A is a front view and FIG. 2B is an end view of IIB-IIB.
In the following description, the same reference numerals are used for the members having the same functions as the mask 1A according to the first embodiment already described, and the description thereof will be omitted as appropriate.

In the mask 1B according to the second embodiment, the piezoelectric member 4B is provided not on the mask main body 2B but on the ear hook portion 3.
When the piezoelectric member 4 is provided on the ear hook portion 3, it is preferable to use a piezoelectric material such as piezoelectric rubber or a piezoelectric resin because the ear hook portion 3 has a thin string shape and is flexible.
In this case, as shown in FIG. 2C, the elastic sheet 24B may be arranged on the ear hook portion 3 and the piezoelectric member 4 may be joined thereto. In this case, it is preferable that the ear hook portion 3 is made of the same fiber material as the mask body 2B.

The mask body 2B has a laminated structure in which two collection filters 22 and two conductive filters 21 are alternately superposed. Each filter has a four-layer structure in which a collection filter 22, a conductive filter 21, a collection filter 22, and a conductive filter 21 are laminated in this order from the outside to the inside when the mask is worn. Therefore, the collecting effect and the inactivating effect can be doubled. Further, it may have a two-layer structure of a collection filter 22 and a conductive filter 21. Further, the protective filter 23 may be provided on the inner surface or the outer surface.

As described above, in the mask 1B of the second embodiment, stress is applied to the piezoelectric member 4 provided on the ear hook portion 3 in accordance with the movement of the face of the mask wearer during conversation or the like. Voltage is generated by the piezoelectric effect. Since the conductive filter 21 is electrically connected to the piezoelectric element 4, a voltage is uniformly applied over almost the entire surface.
Therefore, the mask 1B has an advantage that the inactivating effect is unlikely to decrease because a voltage is always applied to the conductive filter 21.

[Third Embodiment]
3A and 3B are views showing the mask 1C according to the third embodiment, where FIG. 3A is a front view and FIG. 3B is a rear view.
4A and 4B are views showing a valve unit of the mask main body 2C according to the third embodiment, FIG. 4A is a sectional view taken along line IVA-IVA, and FIG. 4B is a view showing a modified example of the valve body.

The masks 1A and 1B of the first and second embodiments are provided with piezoelectric members 4A and 4B on the mask main body 2A or the ear hook portion 3, respectively, whereas the mask 1C of the third embodiment is provided on the mask main body 2C. The difference is that the piezoelectric member 4 is provided on the valve body 62 of the provided valve unit 6.

The mask 1C has a planar (substantially hemispherical cup shape) mask body 2C that is convex toward the front side of the paper surface in FIG. 3 (A) and convex toward the back side of the paper surface in FIG. 3 (B), an ear hook portion 3, and a nose fit. It has a member 5 and the like. As shown in FIG. 4A, the mask main body 2C is laminated in the order of the collection filter 22, the conductive filter 21, and the collection filter 22 from the outside to the inside when the mask is worn. The collection filter 22 uses a hard member capable of maintaining the surface shape of the mask body 2C.

The mask main body 2C is formed with an opening 2a, and the valve unit 6 is mounted in the opening 2a.
[Valve unit]
As shown in FIG. 4, the valve unit 6 includes an exhaust port main body 61, a valve body 62, a detachable member 63, a relay member 64, a cover member 65, a load adjusting member 66, and the like.

The exhaust port main body 61 is detachably attached to the opening 2a formed in the center of the mask main body 2C. The valve unit 6 is attached to the mask main body 2C by using a removable member 63a such as a hook-and-loop fastener provided on the brim portion 61c formed in the exhaust port main body 61.

The reason for making the mask body 2C removable is that the valve unit 6 can be attached to the mask body 2C only by joining with the removable member 63b provided around the opening 2a of the mask body 2C, so that the mask body 2C becomes dirty. This is because sometimes the mask body 2C can be easily replaced.
Further, since the valve unit 6 can be reused, the mask body 2C can be kept economically and hygienically.
Further, since the valve unit 6 can be mounted at a predetermined position only by joining the detachable members 63 (63a, 63b) to each other, the alignment with the mask main body 2C is easy.

The exhaust port main body 61 is attached to the mask main body 2C so as to surround the opening 2a of the mask main body 2C, and since the inside is a hollow and square tubular member, the inside of the exhaust port main body 61 is for the mask wearer. It forms a flow path through which exhaled air and inspiratory air pass.

(Valve body)
The valve body 62 is fixed to the upper side of the valve seat 61b of the exhaust port main body 6 and elastically deformed so that a gap is created between the lower side and the left and right sides of the valve seat 61b to open and close the valve. can. The valve body 62 is made of a flexible material and is formed into a flat rectangular plate shape. The size of the valve body 62 is formed to be substantially the same as the opening of the exhaust port main body 61, and the opening of the exhaust port main body 61 is opened or closed.

(Piezoelectric member)
When stress acts on the piezoelectric member 4 due to elastic deformation of the valve body 62 to cause bending, the piezoelectric effect (piezo effect) generates positive and negative charges on both surfaces polarized in the thickness direction according to the stress. It is a member to be provided, and is provided on the surface of the valve body 62. For the piezoelectric member 4, for example, a piezoelectric material having a thickness of about 0.1 to 1.0 mm, such as piezoelectric ceramics or polyvinylidene fluoride (PVDF), can be used. The piezoelectric member 4 is electrically connected to the relay member 64 by a lead wire 4a.

(Relay member)
The relay member 64 (64a, 64b) is a connector for detachably relaying between the piezoelectric member 4 and the conductive filter 21. The relay member 66 is for electrically connecting the piezoelectric member 4 and the conductive filter 21 when the valve unit 6 is detachably attached to the mask body 2C.

(Cover member)
The cover member 65 is formed so as to cover the periphery of the exhaust port main body 61 and the valve body 62, and is for protecting the cover member 65 from an external physical impact. The cover member 65 has a plurality of openings formed in a grid pattern, so that the exhaled air and the inspiratory air of the mask wearer flow smoothly.

(Load adjustment member)
The load adjusting member 66 is provided between the valve body 62 and the cover member 65, and is a coil spring or the like that urges the valve body 62 to close the opening of the exhaust port main body 61 (hereinafter referred to as a valve closed state). It is an urging member of. As described above, the load adjusting member 66 can maintain the valve closed state even when the mask wearer is not breathing, that is, the air flow is not generated.
As a result, it is possible to prevent an unstable state in which a gap is formed between the opening of the exhaust port main body 61 and the valve body 62, and the mask wearer passes the collection filter 22, the conductive filter 21, and the like. It is possible to prevent inhalation of no air.

(Validation example of valve body)
FIG. 4B is a diagram showing a modified example of the valve body (load adjusting member) of the valve unit according to the third embodiment.
The valve body 62-2 is configured to provide a load adjusting member 66-2 such as a weight at the tip of the valve body. As a result, the valve body 62-2 is in a closed state due to the rotational moment generated by the weight of the load adjusting member 66-2 even when the mask wearer is not breathing. Can be maintained.

(Use of load adjustment member)
The load adjusting members 66, 66-2 can make adjustments to further reduce or weight the exhaled air volume when the valve bodies 62, 62-2 are moved in the valve opening direction.
As a result, the mask wearer can apply a load to the cardiopulmonary function by repeatedly breathing, so that the cardiopulmonary function training such as recovery, maintenance, and enhancement of the respiratory function can be performed.

(Another use of nose fit member)
In the third embodiment, the nose fit member 5 is arranged in the outermost layer and the innermost layer of the mask body 2C. By arranging in this way, the mask 1C can form a capacitor structure in which a dielectric is sandwiched, with two nose-fitting members 5 (5a, 5b) serving as electrode plates on both sides. Therefore, the electric charge generated by the piezoelectric effect of the piezoelectric material 5 can be stored between the nose fit members 5a and 5b. Then, when the piezoelectric effect is not working, the mask body 2C can discharge the stored charge, so that the continuity of the inactivating effect and the collecting effect of the mask 1C can be improved.
Further, when the piezoelectric effect is not working, the mask body 2C can discharge the stored charge, so that the collection filter 22 can be recharged, thereby improving the continuity of the collection function. be able to.
Further, it can be used as a storage battery for the power supply processing unit of the mask side device 7, which will be described later.

According to the mask 1C of the third embodiment described above, when the mask wearer exhales, the valve body 62 moves in the valve opening direction by exhalation to open the opening of the exhaust port main body 61. On the other hand, when the mask wearer inhales, the valve body 62 moves in the valve closing direction by the intake air and closes the opening of the exhaust port main body 61.
Therefore, when the mask wearer exhales, the exhaled breath is discharged through the mask body 2C and the valve body 62, and when the mask wearer inhales, air can be inhaled through the mask body 2C.
That is, when the mask wearer inhales, the air that has passed through the collection filter 22 or the conductive filter 21 of the mask body 2C is inhaled, so that the filter effect can be maintained.

According to the mask 1C of the third embodiment, there are the following effects.
(1) In addition to the effects of the first and second masks 1A and 1B, since the exhaust valve 62 is provided, the exhaled air is smoothly exhausted from the exhaust valve 62, heat is not trapped, and it is comfortable to use.
(2) Since the valve unit 6 can be attached to and detached from the mask body 2C, when the mask body 2C becomes dirty, it can be easily replaced, so that the valve unit 6 can be reused and the mask body 2C can be reused. 2C can be kept economical and hygienic.
(3) Due to the elastic deformation of the valve body 62, the deformation is concentrated on the valve body, so that the power generation efficiency of the piezoelectric member 4 is good.

In S130, the control unit 86 acquires respiratory data.
Based on the respiration data transmitted from the communication unit 73 of the mask 1C, the control unit 86 acquires the respiration data together with the time information capable of specifying the time at which the respiration data was acquired. As a result, the specified respiratory data display mode can specify and display the behavior of the mask wearer during daily life (normal time), sleep time, work time, exercise time, and the like.

In S140, the control unit 86 calculates and processes the acquired respiratory data to generate a signal capable of observing a change in the physical condition of the mask wearer.

In S150, the control unit 86 generates a respiration-related graph in which changes in physical condition can be easily observed visually or audibly by using images and sounds such as time-series graphs so that the user can easily see them.

In S160, the control unit 86 stores the data generated by arithmetically processing the acquired respiratory data in the storage unit 82.

In S170, the control unit 86 converts the respiratory data transmitted from the mask 1C, stores it in the storage unit 810, outputs the converted signal after the fact, and displays it on the display unit 83.

In S180, the control unit 86 determines whether or not to end the measurement of the respiratory data. The control unit 86 determines that the measurement of the respiratory data is terminated when the predetermined measurement termination condition is satisfied. As the measurement end condition here, for example, it is performed by the user performing an end operation of the operation unit 84 or the like.
The control unit 850 proceeds to the process of S190 when it is determined that the measurement end condition is satisfied (S180: Yes), and when it is determined that the measurement end condition is not satisfied (S180: No), S130. Return to the processing of.

In S190, the control unit 86 extracts the respiratory data in the selected display mode from the storage unit 82, displays it on the display unit 83, and ends the process.

When the calculated respiratory data detects an abnormal value in S140, it is preferable that the signal indicating the abnormal state is output to the display unit 83 in S170.
For example, the standard breathing rate for adults is 12 to 18 breaths / minute, although it varies slightly depending on the age. Therefore, if the breathing rate is not within this range, the control unit 86 may drive the display unit 83 so that the display unit 83 displays an alarm with a color or sound different from the normal state.

As described above, according to the third embodiment, there are the following effects.
(1) In the mask 1C of the present embodiment, the valve body 62 opens and closes each time the mask wearer breathes, and the piezoelectric member 4 provided on the valve body 62 bends accordingly. Therefore, the piezoelectric member 4 Can generate voltage. Therefore, every time the mask wearer breathes, a voltage can be generated on the surface of the mask body 2C electrically connected to the piezoelectric member 4, so that micropathogens adhering to the mask body 2C are inactivated for a long period of time. Can be made to.

(2) Since the mask 1C of the present embodiment is provided with the valve unit 6 on the mask main body 2C, the mask wearer can easily breathe and reduce discomfort such as stuffiness and suffocation. Since the valve unit 6b is detachably attached to the mask body 2C, the mask body 2C can be easily replaced even if the mask body 2C becomes dirty, and the valve unit 6 is reused. Therefore, it is economical and the mask body 2C can be kept hygienic.

(3) In the mask 1C of the present embodiment, the detection unit 71 can detect respiratory data such as the respiratory frequency, the respiratory depth, and the respiratory state of the mask wearer. Since the detection unit 71 is supplied with electric power from the piezoelectric member 4 having a power generation function provided in the valve body 62, a small battery can be used without requiring a large capacity battery or the like, and the mask body 2C can be made small. It can be made lighter and lighter.
Further, since the mask 1C and the respiratory information processing apparatus 8 communicate with each other by wireless communication, even the respiratory data when the mask wearer is exercising can be easily remoted by using images and voices such as a time series graph. Can be observed.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications and modifications can be made within the scope of the present invention.
(1) For example, in the above-described embodiment, the shape of the exhaust port main body 6 has been described as an example in which the inside is formed in the shape of a hollow square cylinder, but the inside may be formed in the shape of a hollow cylinder.
Further, if the signal processing unit 72, the communication unit 73, and the power supply processing unit 74 are added to the valve unit 6, the reusability thereof is improved.
(2) The order in which the members constituting the mask main bodies 2A, 2B, and 2C are arranged may be other than the above-mentioned order, and the functions such as flexibility and breathability of the masks 1A, 1B, and 1C must be impaired. For example, the number of members can be changed as appropriate.
For example, the mask body 2A can be laminated by sandwiching the elastic filter 24 to which the piezoelectric member 4 is bonded between the conductive filters 21. As a result, wiring between the conductive filter 21 and the piezoelectric member 4 is unnecessary or the wiring length can be shortened.
