Abstract

A cooling band, wherein PVA-made sponges (201 to 203) expand when impregnated with water to positively contact the front side of a water induction sheet (22) and the retained water quickly permeates into the entire front side of the water induction sheet due to capillarity. The front side of the water induction sheet consists of fine fibers and has a very large microfiber surface area to allow permeated water to actively vaporize in close contact with air and absorb heat of vaporization thereby lowering the ambient temperature. The water induction sheet is very thin and has a small heat resistance so that a low temperature on the front side quickly transmits to the rear side to cool the head. If water is supplied to sponges, a cooling effect is recovered to permit many repeated uses.

Description

Description Cooling band Technical field

BACKGROUND OF THE INVENTION The present invention relates to a cooling band that is worn on the head or the like to cool a worn part when the user is active outdoors or in a fever during a hot season.

It is advisable to wear a hat during summer days, especially when working outdoors on hot days where the sun is shining strongly, to prevent direct sunlight on the head. However, wearing a hat covers the entire head, preventing heat radiation from the head and causing a lot of sweat on the head. Moreover, since the head is in close contact with the hat, sweat is difficult to evaporate, causing unpleasant phenomena such as dripping sweat on the head or sweating down the face.

At present, air conditioners have become widespread and offer a wide range of functions, from small home appliances to large ones that centrally control the temperature of each room in a building and control the entire building at an appropriate temperature. What you have is provided. However, the air conditioner can only be used indoors and cannot be used outdoors. Therefore, no matter how popular the air conditioner is, if it is necessary to work outdoors during the hot summer months, or when recreational activities such as fishing, sports such as golf, or watching sports, There has been no effective means of overcoming the heat. Disclosure of the invention

The present invention has been made based on the above circumstances, and an object of the present invention is to provide a cooling band which has a simple structure, has a high cooling effect, and can be used repeatedly.

In order to achieve the above object, the cooling band of the present invention is mounted on the side in contact with the body. A water guiding means that is made of a material that allows water to penetrate into the surroundings while being attached to the body, and a water guiding means that is provided so as to be in contact with the water guiding means, retains the water, and transfers the held water to the water guiding means. A water retention means for supplying while penetrating the front surface, and a state in which the water conduction means and the water retention means are attached such that one surface of the water conduction means contacts the head and the water retention means contacts the other surface. And a band body attached to the head.

The band body is, for example, formed by molding plastic. A sponge can be used as the water retention means. BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is a perspective view of a cooling band according to an embodiment of the present invention,

FIG. 2 is a perspective view of a state in which components constituting the cooling band in FIG. 1 are removed and viewed obliquely from behind. BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the best mode for carrying out the invention according to the present application will be described with reference to the drawings.

As shown in FIGS. 1 and 2, cooled band 1 0 of the present embodiment comprises an elongated belt-like band body 1 1, and three of the sponge 2 (^ ~ 2 0 _3, the water guide sheet 2 2 Nde contains configuration In addition, a small convex portion 12 is provided on the front side of one end of the band main body 11 and the other end has five (5 in many cases) penetrating from the front to the back. A fixing hole 13 is provided. The cooling band 10 is fixed to the head by the projections 12 and the fixing holes 13. However, the fixing method is not limited to this. For example, a rubber band may be arranged at a portion coming to the back of the head, and the elastic band may be used to fix the head to the head.

In the present embodiment, used as a three sponge 2 0 i~2 0 ₃ PVA of (Poribiniruaru call) made. PVA is highly water-absorbing and can hold significant amounts of water. However, instead of a PVA sponge, paper or cloth that easily absorbs water can be used. The band body 1 1, four vaporizing section 1 4 to 1 4 _4, also has three sponge containing portion 1 5 i-l 5 ₃ is provided between the vaporization section. Vaporizing section 1 4 E to 1 4 ₄ consists box-shaped portion of the cuboid covering the opening and its front. Thus, the vaporization section, the dimensions are different, is substantially the same as the sponge containing portion 1 5 i-l 5 ₃ in structure, the vaporizing section 1 4 ₁ to 1 4 ₄ and the sponge containing portion 1 5 ₁ to 1 5 _3, as shown in FIGS. 1 and 2, longitudinal slits are provided a number. Note that the number of the vaporizing section and the sponge accommodating section is not limited to the above numbers, but may be provided in an appropriate number according to the application.

The material of the band body 1 1 is soft plastic and is molded in a mold. Therefore, the convex portion 1 2 constituting each part of the band body 1 1, the fixing holes 1 3, air I arsenide unit 1 4丄to 1 4 _4, the sponge containing portion 1 5 to l 5 _3, and a number of slits , Are molded together.

The water guide sheet 22 is very thin, and the back side (the side in contact with the head) should be made of water-permeable cloth, for example, by waterproofing the cloth or sticking water-impermeable vinyl. On the other hand, the front side (the side not in contact with the head) of the water guide sheet 22 is made of a fibrous material, and its microscopic surface area is very large. It quickly penetrates the entire body by capillary action. However, since this water does not permeate to the back side, even if the water guide sheet 22 gets wet, the wearer's head does not get wet. However, it is not necessary to provide waterproofing or the like to prevent water from penetrating to the back side when the mounting part is used in such a way that the mounting part may be slightly wet.

Sponge 2 (^ ~ 0 ₃ is housed in the sponge containing portion 1 5 i to 1 5 ₃ corresponding band body 1 1. Then, in a state of being accommodated in the sponge accommodating portions corresponding to the sponge, the band body 1 Adhere and fix the water guide sheet 22 to the back side of 1. At this time, the front side of the water guide sheet 22 faces the back side of the band body 1 1. Bonding method of the water guide sheet 22 For example, heat bonding is performed in consideration of easiness of operation, cost, etc. As described above, the cooling band 10 of the present embodiment can be easily assembled. ₃ by keeping accommodated in the sponge containing portion 1 5 i~ 1 5 _3, can each sponge is prevented from being dried in a short time. When using a cooling band 1 0, first, each sponge revenue volume portion 1 5 i-l 5 ₃ parts of the cooling band 1 0 greatly curved, wide open there slit, by injecting water from it inclusion of water in the sponge 2 0 i~2 0 _3. Sponge 2 0丄~ 2 0 _3, since upon absorption of water the volume is expanded, to touch reliably contact with the water guide sheet one DOO 2 2, the front side of the water guide sheet 2 2, Sponge 2 0-2 0 ₃ Ensures that water is supplied.

Then, the cooling band 10 is wrapped around the head, and the projection 12 is fitted to the hole 13 at a position corresponding to the dimensions of the head, thereby mounting the head on the head. At this time, since the cooling band 10 is curved as a whole, a large number of slits are opened, from which air and water vapor can enter and exit relatively freely. However, since the slits are small, the water does not vaporize excessively from the water guide sheet 22 even when a strong wind blows outdoors. If necessary, the front face of the box-shaped portion of the vaporizing section 1 4 to 1 4 _4, a portion between the ie slit slit Bok, provided a large number of fine holes, more is left containing air and water vapor You may make it easy.

Sponge 2 (^ ~ 2 0 ₃ from the water is supplied to the water guide sheet 2 2, when the entire front side of the water guide sheet 2 2 Te cowpea capillary action water penetrates, the water is in contact with air and tightly When 1 cc of water evaporates, it absorbs about 580 calories of heat from the surroundings and lowers the temperature of the surroundings.The vaporizing sheet 22 is made thin and has low thermal resistance Therefore, the low temperature on the front side is quickly transmitted to the back side, effectively cooling the wearer's head in contact with the head, and the low thermal resistance of the water guide sheet 22 reduces the body temperature of the head. easily transmitted to the front side, the vaporization of water is promoted by the heat, but not the cooling effect further heat absorption is increased. water sponge 2 0 i~2 0 ₃ is fully vaporization, if supply of water However, the cooling effect is restored again, and Can be.

As the cooling band in this embodiment, the vaporizing section 1 4 to 1 4 _4, when the same structure as the sponge containing portion 1 E-丄5 _3, when viewed from the outside, the entire cooling band 1 0 Are unified in terms of design, and this has become a feature of the appearance, and is a factor that attracts consumers.

The embodiment of the present invention has been described above. The present invention is not limited to the embodiment, and various changes can be made within the scope of the gist described in the claims. For example, the back side of the water guide sheet 22, that is, the side in contact with the head can be covered with a metal having high thermal conductivity such as aluminum foil. This not only increases the waterproofing effect, but also makes it easier for the cold temperature on the front side to be transmitted to the head.

As described above, according to the cooling band of the present invention, the water held by the water retaining means is spread over the entire outside of the water introducing means by the material on the front side of the water introducing means, and the water is brought into direct contact with the air. As a result, the water evaporates vigorously, and as a result the water draws heat from the surroundings during the evaporation, thereby cooling the head. Also, by providing the water retention means separately from the part where the water evaporates, the water conduction means, which is the part where the water evaporates, can be made thinner, and as a result, the heat resistance decreases and the water evaporates. The low temperature cooled by the air is transmitted directly to the head, increasing the cooling effect of the head. Furthermore, if a sponge or the like is used as the water retention means, even if all the water retained is vaporized, water can be easily replenished, so that the water can be used repeatedly. In addition, it can be easily worn on the head by the band itself, and has the same function as a normal hair band, so there is no discomfort when wearing it, and it also has fashionability. Industrial applicability

As described above, according to the present invention, the side opposite to the side in contact with the body is made of a material that diffuses water, and this material is made to come into contact with the surrounding air in a state where water is contained. By evaporating water by means of this, the water takes away heat of vaporization from the surroundings during the vaporization, thereby lowering the temperature near the body surface and forcibly increasing the temperature gradient near the body surface. It cools the body and has a large cooling effect despite its simple structure.Therefore, it should be used as a cooling band to be worn on the head to cool the wearing part when working outdoors in hot weather. Can be.
