Japanese Patent No. 6714904 Patent application 2020-120350

The mask described in Patent Document 1 has a cup part that covers both the mouth and the nose, a breathing part provided in the cup part that allows the wearer to breathe, and a liquid such as water that exists in the cup part and circulates. A liquid passage for cooling and a metal liquid passage component for increasing the heat exchange area of the liquid passage. A lot of liquid steel members are used, and the weight of the cup part becomes heavy because it circulates a liquid such as water, which has a higher specific gravity than air. Since the liquid is circulated, the temperature inside the cup rises as the cup is used for a long period of time compared to when it was first used, and a constant cooling effect cannot be obtained.

The mask described in Patent Document 2 is connected to a cold bag containing a cold insulator and a tube (hollow) inserted into the mask via the cold bag and an air pump, and the tip of the tube on the mask side is sealed. Since one or more holes are provided in the vicinity of the tip of the tube inserted into the mask, the cold air discharged from the tip of the tube inserted into the mask is replaced by the outside air inhaled from the mask. There was a problem that it was diffused by merging with the air, and a certain cooling effect could not be obtained. In addition, since the mask and the pump are simply connected through the air via a tube, there is a problem that it is difficult for the user wearing the mask to move the face and body.

In order to solve the above-mentioned problems, the cool inner mask of the present invention comprises an arc-shaped flat plate, a frame bonded and fixed near the periphery of the flat plate approximately perpendicular to the flat plate, and approximately the center of one of the long sides of the frame. an inner mask body having a notch provided in the inner mask body, a cavity provided in one or more places of the frame body, and a substantially sealed cooling bag capable of generating and sending cold air and a tube connected between the hollow portion of the inner mask body and the cooling bag.

Further, in the cool inner mask of the present invention shown in claim 2, the cooling bag of the cool inner mask described above contains a cooling agent that generates cool air, and the cooling bag is provided with an exhaust port, A tube box that is connected to an air outlet and contains a fan for sending cold air, and forms a closed space with a part of the cooling bag, and a fan air outlet, a fan air outlet, and an inner mask in the tube box. The cooling chamber is a space that covers and encloses the portion of the tube connected to the main body inside the tube box, and the tube in the cooling chamber and the wall surface of the cooling chamber are connected by an elastic body.

An opening is provided in the approximate center of the arc-shaped flat plate of the inner mask body, and a slide plate covering the opening slides, thereby facilitating smooth conversation.

The cool inner mask of the present invention comprises an arc-shaped flat plate, a frame bonded and fixed near the outer periphery of the flat plate approximately perpendicular to the flat plate, and a notch provided approximately at the center of one of the long sides of the frame. an inner mask body having cavities provided at one or more locations of the frame; a nearly sealed cooling bag capable of generating and sending cool air; and a cavity of the inner mask body. and a tube connected between the cooling bags, the cooling bags contain a cooling agent that generates cold air, an exhaust port provided in the cooling bag, and an exhaust port connected to the exhaust port to send cold air. and a tube box containing a fan for cooling and forming a closed space with a part of the cooling bag, and a tube box in the tube box that includes a fan outlet and a tube connected to the fan outlet and the inner mask main body. It is characterized in that the cold insulation chamber, which is a space that covers and encloses the inner part, the tube in the cold insulation chamber, and the wall surface of the cold insulation chamber are connected by an elastic body, so that the cooling liquid as in Patent Document 1 can be circulated. Since it only supplies gas instead of air, the cool inner mask does not have a heavy load and can be worn comfortably for a long time. In addition, since the air that has come into contact with the cooling agent is sent as cold air, there is the advantage that the inside of the cool inner mask can be kept at a nearly constant temperature for a long time. Furthermore, the refrigerant has the advantage of being inexpensive because it can be easily reused many times by cooling it in a refrigerator.

Instead of directly injecting cold air into the mask by inserting a tube into the mask as in Patent Document 2, an inner mask body separate from the mask is provided under the mask, and the tube is inserted into the inner mask body. By gathering cold air through the air, breathing through the mouth and nose becomes easier, and it has the effect of suppressing the rise in body temperature. In addition, since the cooling chamber is provided, the cold air in the tube can be prevented from dropping in temperature, and the cold air can be delivered more efficiently. In addition, since the tube inside the cooling chamber and the wall of the cooling chamber are connected by an elastic material, even if the user of this cool inner mask moves their face or body, the tube does not separate from the inner mask body. There is an advantage that the user can easily move.

The inner mask main body 1 of the invention is a mask shape retainer in which the mask mounting portion can be cooled, and is used by being mounted under a normal mask.

As shown in FIG. 1, the inner mask main body 1 is used by covering the inner mask main body 1 with a generally used mask 7 (illustrated by a dotted line because it is outside the scope of the present invention).

1 to 5, the inner mask body 1 is connected to the fan exhaust port 25 in the tube box 21 by the tube 6, and the fan 23 is installed in a sealed state with the tube box 21 through the fan 23. In the cold insulation bag 11, a cold insulation agent 16 is wrapped in a heat insulating material 17 via a ventilation pipe 18 and stored below the cold insulation bag 11. The cooling bag 11 is installed above the outside air introduction pipe 12 and is connected to the outside air through the outside air introduction pipe 12 . Furthermore, below the outside air introduction pipe 12, a moisture absorbing member 15 is provided for collecting and absorbing air condensation generated by the refrigerant.
Since the tube box 21 and the cooling bag 11 installed in a sealed state are integrated, a tool bag 10 for storing them may be provided.

A fan 23 is connected to the inside of the tube box 21 as shown in FIG. Cold air is sent from the cooling chamber 22 to lower the temperature of the tubes in the cooling chamber 22 .

Further, the tube 6 inside the cold storage chamber 22 is connected to the wall surface of the cold storage chamber 22 by an elastic member 28 and protrudes from the tube 6 from the tube outlet in the guide-like tube box. As a result, when a person wearing the cool inner mask of the present invention moves their face or body, they are able to move in the space inside the cooling chamber with a so-called play distance, and the inner mask main body 1 wearing the cool inner mask can move. It will be less likely to shift. Here, rubber, spring, resin, or the like can be used as the elastic body that connects the tube 6 and the wall surface of the cold insulation chamber 22 .

Here, the inner mask main body 1 is desirably lightweight so that it can be used comfortably by the user.

Although the length of the tube 6 is not fixed, the longer the tube 6, the lower the temperature of cold air. Furthermore, since the tube 6 holds cold air, it is preferable to use a material that is suitable for low temperature. For example, a silicon tube can be used.
Further, the portion where the tube 6 is exposed is covered with a heat insulating material or subjected to a heat insulating treatment, so that the temperature drop of the cold air inside the tube 6 can be suppressed.

Although not shown, the tool bag 10 is held by a belt or the like on the back, chest or waist. Bag 10 is preferably held on the chest.

Further, as shown in FIG. 6, which is the second embodiment of the cool inner mask of the present invention, an opening is provided in the approximate center of the arc-shaped flat plate of the substrate 2 of FIG. 2 to cover the opening. Conversation is made smooth by opening the slide plate (claim 4).

As described above, in the cool inner mask of the present invention, cold air is directly supplied to the nose located directly above the inner mask body 1, and in the case of mouth breathing, the mouth is covered with the inner mask body 1, so cold air is inhaled. easy to breathe. Warm breath exhaled from the nose does not flow back into the inner mask body 1 because cool air is always exhaled from the inner mask body 1. - 特許庁Similarly, warm breath is discharged out of the inner mask main body 1 together with cold air, and at the same time, cold air is constantly supplied into the inner mask 1 .

In addition, it is connected to a cooling bag that separates water droplets that have condensed from the cooling agent in the cooling bag and can be discharged to the outside, and a tube in the tube box that is connected to the cooling bag in a sealed state via a fan, and sent by the fan. Since the cooled air is supplied to the inner mask main body 1, there is an advantage that the cooled air can be supplied for a long time with little temperature change. In addition, since the tubes in the tube box are connected to the wall surface of the cold insulation chamber by an elastic body, there is an advantage that even if the user wearing the inner mask body 1 moves, the mounting position of the inner mask body 1 does not easily shift. It has the advantage that it can be used easily by simply replacing the cooling agent in the bag.
