As described in detail below, the face mask system 1 of the present embodiment includes an ultraviolet irradiation mechanism that irradiates ultraviolet rays for inactivating viruses and the like contained in the aerosol collected by the mask filter.

FIG. 2 is a partial cross-sectional view for explaining an example of the internal configuration of the face mask system according to the embodiment of the present invention. Further, FIG. 3 is an exploded perspective view for explaining an example of the configuration of the face mask system according to the embodiment of the present invention, and FIG. 4 is a mask main body of the face mask system according to the embodiment of the present invention. It is an exploded perspective view for demonstrating an example of a part. In the example of FIG. 2, the mask main body 10, the filter 30 attached to the front surface of the mask main body 10, and the cover 20 removed from the mask main body 10 are shown. In the example of FIG. 3, the mask main body is shown. For the portion 10, a housing portion 12 and an electric fan 13 separated from the housing portion 12 are shown.

The housing portion 12 defines a substantially appearance configuration of the mask main body portion 10 and has a cup-shaped concave portion. The mask body portion 10 (housing portion 12) has a first opening 12a on the rear side, that is, on the side that comes into contact with the user's face when the face mask system 1 is worn, and the first opening on the front side thereof. It has a second opening 12b that communicates with the portion 12a. Communication means that a path as a fluid path is secured. As a result, when the face mask system 1 is attached to the user's face, the mask body% has a concave portion that covers the mouth and nose along the shape of the user's face through the first opening 12a. It is configured to get. The housing portion 12 may be provided with an elastic sealing portion such as silicon so that the mask main body portion 10 is in close contact with the user's face along the first opening portion 12a. Further, although not shown, the housing portion 12 may be provided with an external interface such as a power supply operation switch or a USB interface.

A filter 30 is detachably attached to the second opening 12b formed in the housing portion 12. Further, a plurality of first connecting members 141 are provided around the second opening 12b on the front surface of the housing portion 12. The first coupling member 141 is a magnetic material such as a neodymium magnet or a ferrite magnet. In this example, four first connecting members 141 are provided around the second opening 12b. As will be described later, the first coupling member 141 integrally constitutes the coupling portion 14 with the second coupling member 142 (see FIG. 5) provided at the corresponding positions on the inner surface of the cover 20. That is, the coupling portion 14 couples the mask main body portion 10 and the cover 20 by the magnetic coupling force between the pair of the first coupling member 141 and the second coupling member 142. In the present disclosure, the particular coupling portion 14 may be further configured to function as an electrical contact (electrode) portion. As an example, at least some of the pair of first coupling members 141 and second coupling members 142 may themselves be conductive and may be configured as a first electrode and a second electrode, respectively. More specifically, the first coupling member 141 and the second coupling member% are formed by plating on the above-mentioned neodymium magnet, ferrite magnet, or the like, and the conducting wire is connected. As another example, the pair of the first coupling member 141 and the second coupling member 142 are provided with a pair of first electrodes and a second electrode constituting the electric contact portion, and the pair of the first electrodes and the pair of first electrodes are provided. The second electrode is electrically connected to the mask main body 10 when the cover 20 is coupled to the second electrode. As yet another example, the electrical contact portion may be provided independently of the coupling portion 14.

The housing portion 12 houses the power supply 15 inside the housing portion 12. The power source 15 is, for example, a lithium battery or the like. In this example, the power source 15 includes, but is not limited to, a first power source 15a for rotationally driving the electric fan 13 and a first power source 15b for emitting light from the ultraviolet light emitting element 40. For example, the electric fan 13 and the ultraviolet light emitting element 40 may be configured to receive electric power from one power source 15. Alternatively or additionally, the face mask system 1 may be configured to receive power from an external mobile power source, for example via a USB interface. This enables the face mask system 1 to be used for a long time. The USB power cable connected to this USB interface may be made of, for example, a material having an expansion / contraction function. As a result, it is easy to handle, and the USB power cable expands and contracts according to the movement of the user, so that the troublesomeness at the time of mounting is reduced. Further, the housing portion 12 houses the electric fan 13 so as to face the second opening portion 12b, thereby forming the mask main body portion 10. The electric fan 13 is fixed to the housing portion 12 by, for example, a fastening member such as a screw. In the present disclosure, the electric fan 13 is in the form of a blade called a so-called radial fan, but the electric fan 13 is not limited to this, and various types can be applied. The electric fan 13 and the power supply 15 are electrically connected by, for example, a flexible cable 16. The electric fan 13 is supplied with electric power from the power supply 15 when the power switch (not shown) provided in the mask main body 10 is turned on, the fan (blades) rotates, an air flow is generated, and a filter is generated. Inhale outside air through 30.

A protective wall 17 that reflects ultraviolet rays is provided on the back surface of the electric fan 13 so that the ultraviolet rays emitted from the ultraviolet light emitting element 40 and passing through the filter do not reach the surface of the user's face (see FIG. 6). .. Alternatively, the protective wall 17 may be made of a material that absorbs ultraviolet rays.

The mask main body 10 includes a control unit 18 including an LED driver (not shown) for driving the ultraviolet light emitting element 40 described later. The control unit 18 is provided, for example, in an arbitrary space inside the housing portion 12. As an example, the control unit 18 is mounted on the flexible cable 16 and housed in the housing portion 12. The control unit 18 operates using the electric power supplied from the power source 15 and controls the LED driver that drives the plurality of ultraviolet light emitting elements 40. The LED driver generates and outputs a drive signal for driving the ultraviolet light emitting element 40 under the control of the control unit 18. The drive signal can be, for example, a pulse width modulation (PWM) signal. The drive signal is supplied to the ultraviolet light emitting element 40 via the coupling portion 14 that functions as an electrical junction portion. The control unit 18 controls the LED driver, for example, so that the ultraviolet light emitting element 40 emits light intermittently at a predetermined cycle.

The filter 30 is a filter that adsorbs and adheres fine particles and the like in the air existing as an aerosol and collects them, and known ones can be used. In the present disclosure, the filter 30 is a filter having a two-layer structure including a pre-filter 30a and a main filter 30b (see FIG. 2), but the filter 30 is not limited to this and may have a single-layer structure. When the pre-filter 30a is used, it is possible to suppress the acceleration of deterioration of the collection performance of fine particles and the like of the main filter 30b and suppress the replacement frequency of the main filter 30b. The filter 30 may be, for example, a non-woven fabric obtained by molding polypropylene (PP) or polyethylene terephthalate (PEP) by a melt blown manufacturing method, but the filter 30 is not limited thereto. Further, the filter 30 may be a material that reflects ultraviolet rays. For example, in the case of the above-mentioned polypropylene non-woven fabric, the ultraviolet reflectance is about 97%. In this way, when the filter 30 is made of an ultraviolet reflective material, it is possible to effectively reflect the ultraviolet rays emitted from the ultraviolet light emitting element 40 and effectively inactivate the virus or the like collected by the filter 30. can.

The cover 20 is configured to be coupled to the front surface of the mask body 10 in order to protect the filter 30 and to give the appearance decoration of the face mask system 1. As will be described later, an ultraviolet light emitting element 40 for irradiating the filter 30 with ultraviolet rays is provided on the inner surface of the cover 20, that is, the surface facing the filter 30. A predetermined space is formed between the mask main body 10 and the cover 20 so that the ultraviolet rays emitted from the ultraviolet light emitting element can efficiently irradiate the filter.

Further, when the cover 20 is connected to the front surface of the mask main body 10, a slit-shaped outside air interface 20a for passing the breathing gas of the user is formed between the mask main body 10 and the cover 20. It is composed of. That is, the user's breathing gas is ventilated through the slit-shaped outside air interface 20a formed in at least a part of the outer edge portion of the cover 20.

The cover 20 is formed in a curved three-dimensional shape along the contours of the bridge of the nose and the cheek, for example. Such a curved three-dimensional shape contributes to the appearance decoration of the face mask system 1 and prevents the user from directly looking at the ultraviolet light emitting element 40 that emits ultraviolet rays from the outside air interface 20a. Further, an absorbent material that absorbs ultraviolet rays may be provided on the mask main body 10 and / or the cover 20 that forms the outside air interface. With such a configuration, the leakage of the ultraviolet rays emitted from the ultraviolet light emitting element 40 to the outside is effectively prevented.

FIG. 5 is a rear perspective view for explaining an example of the cover of the face mask system according to the embodiment of the present invention. That is, the figure shows the inner surface of the cover 20 facing the front surface of the mask main body 10.

A reflective material 21 is provided on the inner surface of the cover 20, and an ultraviolet light emitting element 40 for irradiating the filter 30 with ultraviolet rays when the cover 20 is bonded to the mask main body 10 is provided in the substantially center thereof. .. From the viewpoint of inactivating viruses and the like, the ultraviolet light emitting element 40 is a UVC-LED that emits ultraviolet rays having a wavelength of, for example, 220 to 450 nm, more preferably 220 to 290 nm, and even more preferably a wavelength in the vicinity of 265 nm. be. In the present disclosure, only one ultraviolet light emitting element 40 is used, but a plurality of ultraviolet light emitting elements 40 may be used, and each of the plurality of ultraviolet light emitting elements 40 has an ultraviolet ray having a different wavelength (for example, an ultraviolet ray having a different wavelength). UVB and UVC) may be emitted.

The reflective material 21 is a material that reflects ultraviolet light emitted from the ultraviolet light emitting element 40 so as to be able to be condensed on the surface of the filter 30. The curved three-dimensional shape of the reflective material 21 is formed substantially along the inner surface of the cover 20, and a predetermined space is formed between the mask main body 10 and the cover 20 to emit light from the ultraviolet light emitting element 40. Ultraviolet rays can efficiently inactivate viruses and the like while being focused on the surface of the filter 30 and reflected by the filter 30.

Further, on the inner surface of the cover 20, a plurality of second coupling members 142 are provided so as to correspond to the plurality of first coupling members 141 provided in the housing portion 12. As a result, the pair of the first coupling member 141 and the second coupling member 142 form the coupling portion 14. The second coupling member 142 is also a magnetic material such as a neodymium magnet or a ferrite magnet, and is plated so as to function as an electric contact (second electrode). The second coupling member 142 that functions as an electrical contact is electrically connected to the ultraviolet light emitting element 40 by a conducting wire (not shown). Alternatively, the pair of first coupling member 141 and the second coupling member 142 may be separately provided with a pair of first electrodes and second electrodes constituting the electric contact portion. Alternatively, the electrical contact portion may be provided independently of the coupling portion 14. As described above, since the coupling portion 14 composed of the first coupling member and the second coupling member also serves as an electrical contact portion, when the cover 20 is removed from the mask main body portion 10, the electrical connection is established. It will be disconnected and the supply of the drive signal to the ultraviolet light emitting element 40 will be cut off. Therefore, even if the cover 20 is unintentionally removed during the light emission of the ultraviolet light emitting element 40, the ultraviolet light emitting element 40 is turned off at the same time, so that the user is not irradiated with the ultraviolet rays.

When the face mask system 1 is attached, the internal space formed by the surface of the user's face and the inner surface of the mask body 10 is the air exhaled by the user's breathing motion and the air generated by the electric fan 13. It can be exhausted to the outside through the outside air interface 20a against the flow. Alternatively, the mask main body portion 10 may be provided with an exhaust valve for exhausting the exhaled air exhaled by the user's breathing motion to the outside in a part of the housing portion 12 (not shown). The exhaust valve opens when the internal space formed by the surface of the user's face and the inner surface of the mask body 10 becomes positive pressure due to the exhaled breath exhaled by the user's breathing motion, and the exhaled air is released to the outside. Exhaust to. As a result, the internal space of the mask main body 10 is maintained at an appropriate atmospheric pressure, and fresh air from the outside flows in, so that the user does not feel stuffy.

Next, the operation of the face mask system 1 configured as described above will be described. FIG. 6 is a diagram for explaining a usage example of the face mask system 1 according to the embodiment of the present invention.

As shown in the figure, the user wears the face mask system 1 so as to cover the mouth and nose, turns on the power, and operates the face mask system 1. As a result, the electric fan 13 rotates, the face mask system 1 starts sucking air through the outside air interface 20a, and under the control of the control unit 18, the ultraviolet light emitting element 40 is intermittently connected at a predetermined cycle. Starts emitting light.

The air flowing in from the outside air interface 20a passes through the space between the mask main body 10 and the cover 20, and further passes through the filter 30 through the second opening 12b, and the aerosol AS in the air passes through the filter 30. Adsorbed to, adhered to, and collected. In the present disclosure, the filter 30 includes a pre-filter 30a and a main filter 30b, each of which can collect aerosol AS according to its characteristics.

Under the control of the control unit 18, the ultraviolet rays emitted from the ultraviolet light emitting element 40 irradiate the filter 30. In the present disclosure, since the filter 30 has a high ultraviolet reflectance, the ultraviolet rays applied to the filter 30 can inactivate viruses and the like while repeating diffuse reflection as shown in FIG. 7. Further, a part of the diffusely reflected ultraviolet rays reaches the reflective material 21 provided on the inner surface of the cover 20 and is reflected toward the filter 30 there, so that the ultraviolet rays are effectively reused for inactivating viruses and the like. At this time, all or most of the ultraviolet rays are not reflected toward the outside air interface 20a, and even if the ultraviolet rays are reflected toward the outside air interface 20a, the ultraviolet absorber provided in the vicinity of the outside air interface 20a. It is absorbed by the surface and does not leak to the outside or is small enough to be ignored. On the other hand, a part of the ultraviolet rays emitted from the ultraviolet light emitting element 40 passes through the filter 30, reaches the protective wall 17, and is reflected toward the filter 30.

By the action of the electric fan 13, the air flowing in from the outside air interface 20a is purified by the filter 30 and reaches the first opening 12a. This allows the user to breathe purified air. Further, when the user exhales in the breathing motion, the space inside the mask main body 10 becomes positive pressure, whereby the user's exhaled air is discharged from the outside air interface 20a against the air flow by the electric fan 13. To.

As described above, according to the present embodiment, the face mask system 1 captures the aerosol in the air taken in through the outside air interface when the user wears it by the filter 30 provided in the mask main body 10. On the other hand, since the filter 30 is irradiated with the ultraviolet rays emitted from the ultraviolet light emitting element 40, the viruses and the like contained in the aerosol collected by the filter 30 are exposed to the ultraviolet rays and are thereby inactivated. In particular, according to the present embodiment, since the filter 30 is made of a material having a high ultraviolet reflectance and the reflective material 21 is provided on the inner surface of the cover 20, the ultraviolet rays emitted from the ultraviolet light emitting element 40 are filtered. While repeating diffuse reflection inside 30, a part of it reaches the reflective material 21 and the protective wall 17 on the inner surface of the cover 20 and further reflects toward the filter 30, so that viruses and the like collected by the filter 30 and the like are collected. Can be effectively inactivated.

Further, according to the present embodiment, the electric power (drive signal) supplied from the power supply 15 of the mask main body 10 to the ultraviolet light emitting element 40 on the cover 20 is supplied via the coupling portion 14 which also serves as an electrical contact portion. Therefore, even if the cover 20 is unintentionally removed during the light emission of the ultraviolet light emitting element 40, the electrical connection is cut off and the supply of the drive signal to the ultraviolet light emitting element 40 is cut off. Therefore, even if the cover 20 is unintentionally removed during the light emission of the ultraviolet light emitting element 40, the ultraviolet light emitting element 40 is turned off at the same time, so that the user is not exposed to the ultraviolet rays and is safe. Sex can be ensured.

Further, according to the present embodiment, since the electric fan 13 is provided in the mask main body 10, the breathing gas necessary for the user's breathing is taken in through the filter 30, and the user does not feel stuffy. do not have.
