The present invention is not limited to the embodiments described below.

First, how to attach the mask temperature variable device according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is an explanatory diagram showing an example of a wearing state of the mask temperature variable device according to the embodiment of the present invention. FIG. 1 shows a state in which a general mask 10 such as a surgical mask is attached to a human head model 90, and a mask temperature variable device 20 is attached together with a mask cover 40.

As shown in FIG. 1, the mask 10 has a mask body 11 that functions as a filter, and attachment strings 12 and 13 that are fixed to the mask body 11 to cover the mouth and nose of a person's face. The mask body 11 is fixed to the human head 90 by using the attachment strings 12 and 13. In this example, the overhead type is shown as the mounting straps 12 and 13, but the present invention is not limited to this. For example, it may be an ear strap to be hung on the ear.

As shown in FIG. 1, the mask temperature variable device 20 (indicated by the dotted line in the figure) and the mask cover 40 (indicated by the two-dot chain line in the figure) of the present embodiment are used as mounting aids. It is attached to the outside of the main body 11. The mask cover 40 is composed of a cover main body 41 that covers the mask main body 11 and mounting strings 45 and 46. The cover body 41 is attached to the human head 90 by the attachment strings 45 and 46. In the example of FIG. 1, the cover main body 41 is in a state of substantially covering the mask main body 11. In this state, the Pelche element 21 fixed to the frame 23 of the mask temperature variable device 20 is energized to cool the outside of the mask body 11. The cover body 41 is provided with a ventilation portion 44 so as not to interfere with the breathing of the user.

Next, an example of the configuration of the mask cover 40 will be described with reference to FIGS. 2 to 4. The cover body 41 has a structure corresponding to various shapes of the mask body 11 to be mounted. Specifically, as shown in FIGS. 1 to 4, the central portion is convexly bulged. This makes it possible to cover a general surgical mask, a 3D structural mask, or the like. In FIGS. 2 and 3, when viewed from the front side, the mountain folds are three-dimensionally formed so as to be gently mountain-folded in the direction indicated by the mountain fold line MF. On the other hand, as shown in FIG. 4, when viewed from the back surface side, the valley folds are three-dimensionally formed so as to gently fold in the direction indicated by the valley fold line VF.

As described above, the mask cover 40 functions as an auxiliary tool for mounting the mask temperature variable device 20 on the surface of the mask body 11. Therefore, the cover body 41 has a structure capable of covering the mask body 11 together with the mask temperature variable device 20. In this embodiment, it is formed of a material that can maintain a certain form. The material is preferably lightweight. In this embodiment, for example, it is manufactured by molding plastic such as polyethylene. Further, it may be manufactured using a paper material such as kraft paper. Depending on the mode of use, a metal material may be used.

As shown in FIG. 2, the cover main body 41 is provided with holes 42 and 43 penetrating from the front to the back. These holes 42 and 43 are provided so as to open at positions corresponding to the left and right cheeks of the user when the mask body 11 is attached. The shape is a four-sided shape in this example. Of course, it is not limited to this. Further, in the lower center portion, a ventilation portion 44 for facilitating breathing when wearing a mask is provided. The ventilation portion 44 can have various forms as described later.

The cover main body 41 is provided with mounting strings 45 and 46 on both the left and right sides. The attachment string 45 is attached to the upper side, and the attachment string 46 is attached to the lower side. The attachment strings 45 and 46 are connected from one end to the other end, respectively, and are formed so as to be fitted into the human head 90. The attachment strings 45 and 46 are made of, for example, elastic members and are formed to be stretchable. As a result, the mask temperature variable device 20 can be closely fixed to the mask body 11 by the cover body 41. The mounting strings 45 and 46 may have a structure that can be tied. Further, it may be in a band shape.

The heat sink 22 attached to the Pelche element 21 of the mask temperature variable device 20 is inserted into the holes 42 and 43 of the cover body 41 from the back surface side of the cover body 41. The Pelche element 21 and the heat sink 22 are mounted on a frame 23 (shown by a broken line in FIG. 3). A pair of left and right heat sinks 22 are provided and inserted into the corresponding holes 42 and 43, respectively, so that the heat sink 22 can be cooled on the opposite surface (front side of the cover body 41) in the holes 42 and 43. It becomes. Further, the mask temperature variable device 20 is fixed to the cover body 41. As a result, the mask temperature variable device 20 is fixed to the cover main body 41 and is held in close contact with the mask main body 11 by the mounting strings 45 and 46 of the mask cover 40.

As shown in FIGS. 3 and 4, the mask temperature variable device 20 is configured by forming a pair of a Pelche element 21 and a heat sink 22 and attaching the mask temperature variable device 20 to the frame 23. 5 and 6 show a part (one side of the pair) of the configuration of the mask temperature variable device 20. Although not shown, a similar configuration is provided on the opposite side. The frame 23 is made of a material having good thermal conductivity. For example, a pair of element mounting portions 23a on the left and right and a connecting portion 23b connecting them are integrally provided by a metal plate such as aluminum. Since the connecting portion 23b extends from one cheek portion of the user to the other cheek portion straddling the nasal bridge at the time of wearing, the connecting portion 23b is formed in a shape having a curved portion along the face surface (particularly the nasal bridge) in advance. It may be made of a material that can be flexibly bent at the time of mounting, or may be made of a material that can maintain the bent state. The cushioning material 23c is attached to the surface of the connecting portion 23b on the mask body 11 side. The cushioning material 23c is made of a material having good thermal conductivity and good shock absorption, for example, silicon rubber. On the other hand, on the surface of the connecting portion 23b on the cover body 41 side, for example, a heat insulating coating 23d made of a heat insulating paint is provided. The heat insulating coating 23d is formed by applying a resin paint containing fine beads, for example, an acrylic resin paint, for example.

As shown in FIG. 6, the mask temperature variable device 20 includes a cushioning material 23c and a frame 23 (element mounting portion 23a and connecting portion 23b) when viewed from the mask main body 11 side at a position where the Pelche element 21 is arranged. , The Pelche element 21 and the heat sink 22 are provided so as to overlap each other. The Pelche element 21 and the element mounting portion 23a, and the Pelche element 21 and the heat sink 22 are fixed to each other by a heat conductive adhesive. This can reduce the thermal loss between each. As the heat conductive adhesive, for example, an epoxy resin mixed with a heat conductive filler such as alumina or aluminum powder can be used.

FIG. 7 shows a cross section of a part of the cover main body 41. As described above, the cover body 41 is provided with a hole 42. The heat sink 22 of the mask temperature variable device 20 as shown in FIG. 6 is inserted into the hole 42. FIG. 8 shows the inserted state. In this example, in the mask temperature variable device 20, as shown in FIG. 8, the heat sink 22 faces the outside of the cover main body 41 through the hole 42. In this example, it stands out. Therefore, the heat radiated from the Pelche element 21 can be discharged to the outside through the heat sink 22.

In the examples shown in FIGS. 3 and 8, the heat sink 22 is exposed to the outside. Therefore, in consideration of design, the heat sink 22 may be covered with a louver or the like on the outside of the hole 42. Further, a small blower may be added outside the hole 42 to effectively exhaust heat.

Next, the configuration related to the operation of the mask temperature variable device of the embodiment will be described with reference to FIGS. 9 and 10. An example of a state in which the mask cover 40 and the mask temperature variable device 20 are stacked is seen from the outside of the mask cover as shown in FIG. This shows the right outer side of the cover body 41 as seen from the front side. On the other hand, when viewed from the inside of the mask cover, an example of a state in which the mask cover 40 and the mask temperature variable device 20 are overlapped is seen as shown in FIG. This shows the right inner side of the cover body 41 as seen from the back side.

As shown in FIGS. 9 and 10, the mask temperature variable device 20 of the present embodiment includes a USB terminal 28 connected to the power supply unit 60, a USB connector 26 connected to the USB terminal 28 via a cable 27, and a USB connector 26. It has a cable 25 connected to a branch port (not shown) of the USB connector 26 and connected to a connection portion 24 of a pair of left and right corresponding Pelche elements 21. The connection portion 24 is connected to the electrode of the Pelche element 21 and is connected to one end of the external cable 25 by, for example, soldering. In the present embodiment, the cable 25 is pulled out along the attachment string 45 attached to both upper ends of the cover main body 41.

As the power supply unit 60, one capable of supplying electric power corresponding to the USB standard is used. For example, in addition to a dedicated power supply device, a mobile battery, a battery box, a computer, or the like can be used as a power source.

As described above, in order to use the mask temperature variable device 20 of the present embodiment which is in close contact with the mask main body 11, the USB terminal 28 shown in FIG. 9 or 10 is connected to the power supply unit 60. As a result, for example, a current of about 1 A to 1.5 A is supplied to the pair of Pelche elements 21 via the cable 25 and the connection portion 24. As a result, the mask-side surface of the Pelche element 21 becomes an endothermic surface, and the mask body 11 is cooled via the element mounting portion 23a of the frame 23. Further, the mask main body 11 located near the nose bridge of the user is cooled via the integrated connecting portion 23b. On the other hand, the surface on the opposite side of the Pelche element 21 becomes a heat dissipation surface, and the heat released from this surface is radiated to the outside of the cover main body 41 via the heat sink 22.

FIG. 11 shows another embodiment of the present invention. FIG. 11 is a side view of an example of a state in which the mask temperature variable device of another embodiment of the present invention and the mask cover are overlapped with each other as viewed from the inside of the mask cover. The embodiment shown in FIG. 11 is an example in which the electric power from the power supply unit 60 is controlled to increase or decrease the current supplied to the Pelche element 21 to make the temperature change variable. Increasing the current increases the amount of heat absorption, and decreasing the current decreases the amount of heat absorption. By providing the function of reversing the polarity, the endothermic surface and the heat radiating surface of the Pelche element 21 can be switched. This makes it possible to switch the temperature variable for the mask body from the cooling mode to the heating mode. The control unit 29 may include a power supply unit 60.

12 to 15 show a modification of the mask cover 40, particularly a modification of the shape of the ventilation portion. In the example shown in FIG. 12, the ventilation portion 47 is provided with the lower side open, and the ventilation amount can be increased. In the example shown in FIG. 13, the height of the cover main body 41 is reduced so that the lower side is largely vacant to form the ventilation portion 48. In the example shown in FIG. 14, a plurality of slit holes are provided on the lower side of the cover main body 41 to form a ventilation portion 49. In the example shown in FIG. 15, a plurality of through holes are provided on the lower side of the cover main body 41 to form a ventilation portion 50.

FIG. 16 shows another embodiment of the mask temperature variable device 20. In this embodiment, the Pelche element can be mounted on the mask body 11 via the frame without using the mask cover 40. The basic structure is the same as that of the mask temperature variable device shown in FIGS. 5 to 8. Further, although not shown, the same applies to the point that power is supplied to the connection portion 24 via the cable 25. The difference is that the attachment strings 45 and 46 are attached to both ends of the frame 23 so that they can be attached directly to the head.

The distance between the left and right holes 42 and the length of the connecting portion 23b are not limited to the illustrated example. Further, the height positions of the left and right holes 42 are not limited to the illustrated example. For example, the left and right Pelche elements 21 may be configured to be located below the orbit and beside the nose when worn.

As described above, in each embodiment of the present invention, since the mask can be cooled by the Pelche element, the cheek portion of a person is cooled through the mask, it is hard to get stuffy even in a hot season, and the mask is comfortably worn. can do. In addition, there are no moving parts like a fan, it is lightweight and quiet.
