Is usually done. However, in a workplace where hot foods are cooked, workers are constantly exposed to hot air, which puts a strain on the throat and lungs and often accumulates fatigue. This problem is not limited to the food processing industry, but also occurs at work sites where it is difficult to wear a full-scale mask such as dustproof as in the invention of Patent Document 1 when working at a high temperature.

(B) Price Issues In the invention described in Cited Document 1, it is necessary to individually prepare a component that functions as a mask, and there is a problem that the cost is high. That is, there is a request to work at a high temperature or to wear a mask in a high temperature environment, but there is a problem that it cannot be adopted in terms of cost.
(C) Problems in appearance In the invention described in Cited Document 1, when a mask is worn, it often feels strange at first glance, unlike a normal mask. It is okay to wear the cooling mask described in Cited Document 1 at a work site where dust harmful to the human body such as asbestos is flying, but for example, a salesperson who sells food under the scorching sun can see FIG. 17 of Cited Document 1. It can be said that it is difficult for sales promotion to wear a mask that looks strange at first glance. In other words, it is also important that consumers and the general public do not feel uncomfortable with the water-cooled cooling mask.

(D) Countermeasures against new virus infections such as coronavirus Whether or not new virus infections such as coronavirus maintain infectivity even in hot and humid conditions such as summer in Japan is at the time of filing this patent application. Then it is unknown. However, it is clear that wearing a mask is hot and burdensome, at least in a hot environment. From the viewpoint of preventing new virus infections such as coronavirus, if the mask does not look strange to the general public, it should be easily worn when going out such as during business hours, school commuting, and commuting. Was difficult. In addition, there is no such cooling mask at present.

An object of the present invention is to provide a liquid circulation type cooling mask capable of solving each of the above-mentioned problems of the prior art.

[First Embodiment]
1 to 6 are views for explaining a liquid circulation type cooling mask 1 (hereinafter, referred to as a cooling mask 1 for convenience) according to the first embodiment of the present invention.
As shown in FIGS. 2 and 3, the cooling mask 1 basically comprises the liquid path mask portion 4 as a basic component. Further, as an additional configuration, a water absorption holding member 7 and a mask function unit 6 are provided.
Various configurations can be exemplified for the configuration of the combination of the liquid path mask unit 4 and the mask function unit 6.
Further, as an accessory of the cooling mask 1, there is a liquid circulation pipe 17 and a liquid circulation unit 20 as shown in FIG. 7.
As shown in FIG. 7, the liquid circulation unit 20 includes a bottle portion 21 containing ice, a pump portion 24 for delivering liquid, and a delivery pipe 22 for delivering liquid (usually water) in the bottle portion 21. It has a return pipe 23 for returning. The liquid circulation pipe 17 is composed of the delivery pipe 22 and the return pipe 23.
The liquid circulation unit 20 is attached to the body with a belt or the like on the waist or the like.

Further, in the present embodiment, a configuration is adopted in which the mask function unit 6 is arranged outside the liquid path mask unit 4 to cover the liquid path mask unit 4. As shown as an example in FIG. 4, the mask function unit 6 is often a simple mask made of paper, non-woven fabric, cloth, or the like, instead of a high-performance mask that prevents asbestos.
Although not described in this embodiment, a configuration in which the mask function unit 6 is arranged inside the liquid path mask unit 4 can also be adopted.

<Liquid path mask part 4>
As shown in FIG. 1, in the configuration of the present embodiment, the liquid path mask portion 4 is configured by assembling a planar synthetic resin sheet into a three-dimensional configuration.
The liquid passage mask portion 4 includes a liquid passage 3 formed by joining a plurality of synthetic resin sheets, a connecting mouthpiece portion 26 provided at an inlet and an outlet of the liquid passage 3, and a three-dimensional configuration engaging portion 8. , The nose where breathing is easy in the liquid path mask portion 4, at least one intake / exhaust opening 13 provided in the region near the mouth, and the ear hook through portion 15 through which the ear hook portion 14 of the mask function unit 6 is passed. doing.
A liquid circulation pipe 17 is connected to the connection port portion 26.

The liquid passage 4 is formed by using a plurality of synthetic resin sheet materials, and is made of a thin sheet material capable of forming a lightweight mask surface. The configuration and shape of the liquid passage 4 are not particularly limited as long as the liquid can be circulated by the pump unit 24 (see FIG. 7) of the portable liquid circulation unit 20.
In the configuration of the liquid passage 3 shown in FIG. 1, a joining region 38 is provided in the liquid passage 3. The joining regions 38 are arranged at equal intervals per unit area, and have a function of suppressing swelling between two sheets 2 which are liquid passages 3 when a liquid flows.
The liquid circulation tube 17 is generally a tube shape such as a silicon tube. However, it may be a tube of various shapes made of rubber or various synthetic resins.

As the connecting mouthpiece unit 26, the mouthpiece for liquid passages obtained by the applicant in Japanese Patent No. 6232523 can be adopted. However, it does not exclude the adoption of other connection mouthpieces.
Further, in the first embodiment, as shown in FIGS. 1 and 5, the connecting mouthpiece portion 26 is provided in the lower region of the liquid passage mask portion 4.
The three-dimensional configuration engaging portion 8 adopted in this embodiment is composed of a three-dimensional configuration hook portion 11 having a hook portion 10 and a three-dimensional configuration slit portion 12 into which the three-dimensional configuration hook portion 11 is inserted. It has been done.
However, the three-dimensional configuration engaging portion 8 can employ not only the engagement of the three-dimensional configuration slit portion 12 into which the three-dimensional configuration hook portion 11 is inserted, but also various detachable locking means.

The intake / exhaust opening 13 is an example of the intake / exhaust region portion 5.
The main point of the intake / exhaust region 5 is the liquid passage in the region where the intake / exhaust (breathing) can be performed to the extent that the wearer does not feel suffocated even if the wearer performs various operations while the mask function portion 6 having functions such as dust prevention and splash prevention is functioning. It means that it is provided in the mask portion 4. Generally, the intake / exhaust region portion 5 is often formed by means such as an opening (hole) or a notch formed facing the three-dimensional space described later.
However, if the mask function portion 6 is large enough to cover the liquid path mask portion 4, the intake / exhaust region portion 5 may be provided on the outer peripheral edge of the liquid path mask portion 4. As such a configuration, a configuration is conceivable in which an intake / exhaust gap (not shown) is provided between the outer peripheral edge of the liquid path mask portion 4 in which the mask function portion 6 is present and the mask function portion 6.
That is, the intake / exhaust region portion 5 is composed of an intake / exhaust opening 13 including a notch in the present specification, an intake / exhaust gap, and the like.
Further, a configuration having both an intake / exhaust opening 13 and an intake / exhaust gap provided on the outer peripheral edge of the liquid path mask portion 4 can be adopted as needed.

(Intake / exhaust opening 13 and ingenuity by three-dimensional space)
Hereinafter, a device for comfortable breathing will be described with reference to FIG. 6, even though the cooling mask 1 substantially overlaps the two mask portions.
When the liquid path mask portion 4 overlaps with a simple mask such as a normal non-woven fabric and is in close contact with the mask, the ventilation efficiency from the mask function portion 6 decreases, and breathing becomes difficult. Further, if the liquid path mask portion 4 is in close contact with the face 16 too much, it becomes difficult to cool the sucked air.
Therefore, in the present embodiment, as shown in FIG. 6A, the three-dimensional configuration engaging portion 8 (FIG. 1) so that the liquid passage mask portion 4 has a three-dimensional configuration in the respiratory region region 27 around the mouth and nose. (See) is provided so that a three-dimensional space sufficient for breathing is formed in the nose and mouth.

In such a configuration, the liquid path mask portion 4 itself is provided with the first three-dimensional space 28 between the liquid path mask portion 4 and the face 16.
In addition, the first three-dimensional space 28 prevents the mask from coming into close contact with the nose, mouth, and the like in the respiratory region 27.
Further, in the breathing area 27 near the nose and around the mouth, due to the presence of a pair of left and right intake / exhaust openings 13 and 13 on the seat surface of the liquid path mask portion 4, and an intake / exhaust opening 13 provided on the more oral side. The air entering and exiting the intake / exhaust opening 13 does not impair the original function of the mask function unit 6 as shown by the arrow 42 indicated by the one-point chain line in FIG. 6 (a), and most of the liquid path mask unit 4 is the sheet surface. However, it is properly dispersed and you can breathe comfortably.

As a result, even if a large area of the liquid path mask portion 4 is taken to cool the air in the mask, the intake / exhaust area of the intake / exhaust opening 13 is sufficient for breathing comfortably.
On the other hand, the mask function unit 6 also forms a second three-dimensional space 29 between the liquid path mask unit 4 and the mask function unit 6 by adopting a three-dimensional structure that protrudes more than the three-dimensional structure of the liquid path mask unit 4. be able to. By forming the second three-dimensional space 29, it becomes easier to breathe and the cold air space around the nose and mouth can be enlarged.

(Structure of ear hook through portion 15)
As shown in FIGS. 1 to 3, the liquid passage mask portion 4 has an ear hooking portion 15. The ear hooking portion 15 has a function of passing the ear hooking portion 14 of the mask function portion 6 provided so as to cover the liquid path mask portion 4 on the outside.

In this embodiment, the ear hook through portion 4 is configured by providing the ear hook through slits 31 and 31 in the seat portions extending on both sides (left and right ear sides) of the liquid passage 3. In the present embodiment, the slit portion 31 for passing through the ear can be formed only by a step of making a cut in a sheet material made of synthetic resin or the like, so that there is an advantage that it can be manufactured at low cost. Further, the ear-hooking slit portion 31 according to the present embodiment has a tear-preventing circular portion at both ends of the slit so that both ends of the ear-hooking slit portion 31 do not tear when a force is applied to the slit. 32 and 32 (see FIGS. 1 and 3) are provided, respectively.

When the cooling mask 1 is used, the ear hook portion 14 of the mask function portion 6 is passed through the ear hook passage slit portion 31 of the liquid path mask portion 4 and the ear hook portion 14 is hooked on both ears. At this time, since a normal simple mask is adopted for the mask function portion 6, the liquid path mask portion 4 naturally fits well on the face by the pulling operation of the ear hook portion 14.

<Mask function unit 6>
Next, the mask function unit 6 will be briefly described.
As described above, a normal simple mask is often used for the mask function unit 6.
Further, it is preferable to adopt a simple mask that naturally has a large three-dimensional structure when worn on the face so that the second three-dimensional space 29 can be formed as described above.
However, since the second three-dimensional space 29 shown in FIG. 6A is less important than the first three-dimensional space 28, it can be adopted even for masks such as pleated masks and cloth masks that are difficult to maintain the three-dimensional shape. It is possible.
Further, as the three-dimensional structure mask as the mask function unit 6, a so-called cup mask or the like having a cup body in advance can be satisfactorily adopted.

<Water absorption holding member 7>
As shown in FIG. 1, in the present embodiment, a water absorption holding member 7 that absorbs and retains condensed water is provided in the liquid passage mask portion 4.
For example, the water absorption holding member 7 may be simply a water absorption member placed in the inner lower region of the concave liquid path mask portion 4. Further, the water absorption holding member 7 may be detachably configured with respect to the liquid path mask portion 4 by using a detachable means 40 (see FIG. 1 (b)) such as a hook-and-loop fastener for the liquid path mask portion 4. ..
The attachment / detachment means 40 may be configured with a hook or the like that can be locked to the liquid path mask portion 4.

Further, the water absorption holding member 7 is provided in the liquid path mask portion 4, and the configuration and shape thereof are not limited as long as the configuration is removable from the liquid path mask portion 4. FIG. 1B shows an example composed of one or a plurality of water-absorbing pads such as a thin rectangular parallelepiped.
As the water absorption holding member 7, a high-performance water absorption pad capable of absorbing water up to 30 to 50 times its weight like a sponge can be exemplified. It can be said that such a water absorption pad is practically preferable as the water absorption holding member 7.
Further, although it is difficult to reuse and the cost is high, a super absorbent polymer (highly absorbent polymer) used for disposable diapers can be contained in a bag or the like. In this case, the water absorption holding member 7 has a disposable structure.

<Action>
The operation of the cooling mask 1 according to the first embodiment will be briefly described.
First, as shown in FIGS. 2 and 3, a person who intends to wear the cooling mask 1 passes the ear hook portion 14 of the mask function unit 6 through the ear hook portion 15 of the liquid path mask portion 4, and the liquid path mask portion. 4 and the mask function unit 6 are overlapped with each other. Then, the liquid circulation unit 20 (see FIG. 7) described above is attached to the body, the liquid circulation tube 17 and the connection mouthpiece portion 26 are connected, and the ear hook portion 14 of the mask function portion 6 is used as a normal simple mask. Hook on both ears of the wearer in the same manner as in the above, and complete the wearing as shown in FIG.
After that, if the pump unit 24 of the liquid circulation unit 20 is driven, it is possible to breathe with the cooled air even if a mask is attached while the ice or the like melts. It can reduce the difficulty of breathing hot air, the burden on workers who have to wear a mask in a hot workplace, and the risk of infections such as coronavirus when the mask cannot be masked due to the heat. ..

As shown in FIG. 1, when a liquid such as water flows in from the connection mouthpiece portion 26 from one of the left and right sides, the water flows into the entire liquid passage 3 and while it flows out from the connection mouthpiece portion 26 from the other side. Since the air in the first three-dimensional space 28 (see FIG. 6) and the second three-dimensional space 29 in the liquid path mask portion 4 is cooled, fatigue can be reduced even in a hot environment or by masking.
Further, when the external temperature is high, the temperature of the four surfaces of the liquid path mask portion through which the cold liquid flows is low, so that dew condensation occurs on the four surfaces of the liquid path mask portion, but the condensed water is absorbed by the water absorption holding member 7 such as the water absorption pad. Since it is retained, discomfort can be reduced.
When the amount of water retention of the water absorption holding member 7 increases, the water absorption holding member 7 is removed from the liquid path mask portion 4, for example, the water absorption holding member 7 is squeezed to remove water, and the water absorption holding member 7 is returned to the liquid path mask portion 4 for comfort again. Can be used.

The cooling mask 1 according to the present embodiment is performed by supplying the cooling mask 1 to the consumer who purchased the liquid circulation unit 20 described above. For example, there is a form in which about 10 to 100 simple masks suitable as a liquid path mask unit 4 and a mask function unit 6 of 2 to 3 are sold as a bundle.
Alternatively, a set of the liquid circulation unit 20 and the cooling mask 1 can be sold, and a simple mask of a type that can be used as the mask function unit 6 can be separately purchased from a mask maker and attached.

[Second Embodiment]
8 to 13 are diagrams for explaining the cooling mask 1 according to the second embodiment of the present invention.
As shown in FIG. 8, the features of the configuration of the second embodiment as compared with the cooling mask 1 according to the first embodiment are as follows.

First, a connection mouthpiece 26 is provided in the upper lateral region on the ear side of the liquid passage mask portion 4, a liquid circulation pipe 17 is connected to the connection mouthpiece 26, and the liquid circulation pipe 17 is placed above the cooling mask 1. It is configured to be pulled out from the lateral area. With such a configuration, as shown in FIGS. 9 and 10, the liquid circulation tube 17 can be pulled out from the ear hooking portion 15 and hung on both ears. Since the ear hook portion 14 of the mask function portion 6 is also passed through the ear hook through portion 15, the liquid circulation pipe 17 can be hidden by the ear hook portion 14 as shown in FIG. 10, and the liquid circulation pipe 17 can be hidden from the mask. It is possible to reduce the discomfort in appearance due to the appearance of.

Next, the water absorption holding member 7 is detachably supported in the liquid path mask portion 4 by engaging the strip portion 18 and the strip portion locking portion 19. Specifically, unlike the configuration of the first embodiment, since the connection port portion 26 is provided in the upper lateral region of the liquid passage mask portion 4, the band is formed in the left and right lower regions of the liquid passage mask portion 4.
