It relates to a cold air functional cap that can last for a long time.

In addition, it is equipped with a cooling function to keep the head cool for a long time when worn in an indoor sauna, a bath or a high temperature outdoor workplace, and the outer layer 10 and the inner layer 20 are injected with air 11 and coolant 21. One or more air inlet 12, air outlet 13, coolant inlet 22, and coolant outlet 23 are respectively provided, thereby injecting and using air 11 and coolant 21 during use. When not in use, the air 11 and the coolant 21 may be discharged to reduce the volume, thereby increasing portability and ease of storage.

Air is a material with very low thermal conductivity, which has excellent thermal insulation effect and can be easily obtained from the surrounding area, and thus has a high useful value as a thermal insulator. When it is confined in a small space so that convection does not occur because it is lower than the thermal conductivity of glass fiber, 0.03k, it shows ideal insulation effect.

Here k usually means thermal conductivity indicating the thermal conductivity of a material, and kcal / mhr ° C unit, which represents the ratio of heat transmitted through an hour when the temperature difference between two sides of the material thickness (m) is 1 ° C, is mainly used. do.

This air insulation effect can be easily seen in the warmth of wearing thin clothes rather than wearing thick clothes in winter as experienced in everyday life.Thermal insulation, double glazing of buildings, and building insulation of porous materials It is widely used where insulation is required.

When air is added, each tube 3 expands and expands, so each shading cloth 5 expands to form a hat, and when not in use, the air of the tube 3 can be removed and carried or stored. Although it is configured to be easy, it does not utilize the insulation function of air and is only used for the purpose of maintaining the shape of the cap by the air pressure by injecting air.

In addition, in the case of the second conventional technology (Registration Utility Model No. 20-254485) for cooling purposes, as shown in FIG. 2, after opening by the zipper 4 ′ between the outer shell 5 ′ and the inner shell 6 ′ of the hat. Inserted, cold water or ice-filled plastic container (1) is inserted between the inner and outer shell of the cap, but there is a problem that the cooling effect by the ice can be maintained for a relatively short time because no separate insulation function is secured .

An object of the present invention is to provide a cold air functional cap capable of maintaining the cooling effect of the coolant inserted into the cap by using the thermal insulation effect of the air to be devised to improve the above problems.

It is preferable that the cooling flow path 26 is provided.

And the outer surface of the outer layer 10 is made of an outer layer of the UV protection material 14, the inner surface of the inner layer 20 is a thinner than the outer layer 10 or the fiber layer 28 or outer layer 10 of waterproof or water repellent material. If the endothelial 27 is formed to be further included it can double the thermal insulation effect.

In addition, the inner layer 20 may further include a fibrous layer 28 that easily absorbs the coolant 21 therein to achieve a comfortable fit, and an inner circumference of the inner layer 20 is connected to the outer layer 10. An additionally sized air layer 30 having an air passage 32 is formed, and an air opening / closing control valve 31 is inserted into the air passage 32 and is operated by operation of the control valve 31. The air 11 introduced into the outer layer 10 is introduced into the size control air layer 30 via the air flow path 32.

On the other hand, the cold air functional cap is the air cap 100 is made of a material having a waterproof or water-repellent material on the inner surface of the inner layer 20 to form the inner space further comprises the endothelial Adjacent to the entire side or attached to be spaced apart from the inner surface and a predetermined space, or through the inner layer and the outer layer further comprises a vent for introducing the outside air, the vent is so that the outside air can be easily introduced It is possible to provide a cold air functional cap having a high wearing comfort.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, like reference numerals refer to like elements, and the size of each element may be exaggerated for clarity and convenience of description.

3 is a perspective view of a cold air functional cap 100 according to a preferred embodiment of the present invention.

As shown in the outer layer 10, the air inlet 12 and the air inlet 12 is injected and discharged to the air outlet 13 and the coolant inlet 22 and the coolant 21 is injected and discharged to the inner layer 20 and The coolant discharge ports 23 are formed to protrude outward, respectively, and the outer layer 10 has an insertion hole 15 formed at a corresponding position to insert the coolant injection hole 22.

In addition, the shape of the cap itself can be applied to various hat shapes such as 'baseball cap' or 'sun cap' in addition to the 'bunger' shape as shown in Figure 1, the cold functional air cap of the present invention itself is a high temperature, high temperature work site The function may be expressed by being used as the endothelial of other hats, such as the helmet used in.

Figure 4 is a side cross-sectional view of the cold air functional cap 100 according to an embodiment of the present invention.

Referring to the drawings, the internal structure of the cold air functional cap 100 is basically composed of an outer layer 10 filled with air 11, which is a heat insulating material, and an inner layer 20 into which the coolant 21 is injected.

Cooling functional air cap 100 having such a structure has a laminated structure in which the outer layer surrounds the inner layer 20 from the outside, the coolant in which the air 11 filled in the outer layer 10 is injected into the inner layer 20. The heat transfer between (21) and the outside air is blocked.

Therefore, the cool air by the coolant 21 is mainly transmitted only to the inside of the hat, and the transfer to the outside of the hat is blocked so that the inner space where the wearer's head is located can preserve the cold air for a longer time.

On the other hand, the heat insulating material can replace the air (11) used in the present embodiment, organic insulating materials including styrofoam, pink board, urethane foam and other plastic materials and inorganic insulating materials such as pearlite, calcium silicate-based, glass surface can be used, but self-weight and portable In consideration of convenience and the like, it is preferable to use the air 11 as in the above embodiment. In addition, the coolant 21 is preferably used to obtain the water commonly available in the surroundings, and of course, the gel of the polymer (gel) may be used to maintain the cooling effect for a long time.

In the method of using the cold air functional cap 100 having the above-described configuration, the wearer first injects the air 11 through the air inlet 12 and fills the air 11 with the outer layer 10. The shape of the cap is completed by the air pressure formed by the air), and then the coolant 21 is injected through the coolant inlet 22 or the coolant functional air cap in the state in which the coolant 21 is injected into the inner layer 20. 100) in the freezer to freeze the coolant 21 to wear it as it is or may be used as the endothelial of another hat.

In addition, the cool air functional air cap 100 filled with the air 11 and the coolant 21 is used for a certain time, and thus, when the temperature of the coolant 21 is increased, it is difficult to expect a cooling effect, so that the wearer only the coolant 21. By discharging the coolant 21 of the cool liquid provided separately to the inner layer 20 or by simultaneously discharging the coolant 21 and the air 11 through the coolant discharge port 23 and the air discharge port 13 It can be reduced to a form that is easy to carry.

In addition, the inner structure of the inner layer 20 is composed of a plurality of zones 25 formed with a partition wall 24, as shown in Figure 5a, the narrow wall 24 so that the coolant 21 can communicate with each other narrow Since the flow path 26 is provided, it is preferable to have a structure capable of minimizing the heat transfer phenomenon due to convection generated by the temperature difference between the coolant 21 and more sustaining the cooling effect.

In addition, as shown in FIG. 5B, the air cap penetrates the air vent 16 through which the outside air flows through the inner layer 20 and the outer layer 10 at the boundary portion of the partition wall 24 through which the coolant 21 is not communicated. It is preferable to be provided additionally, and thus, the air permeability of the air hat is greatly improved, thereby enabling a more comfortable wearing comfort.

On the other hand, such a vent need not be formed only at the boundary of the partition as described above, of course can be modified in various forms in other embodiments without departing from the scope of the invention.

6 is a side cross-sectional view of the cold functional air cap 100 formed by adding an outer skin 14 of the ultraviolet ray preventing material to the outer surface of the outer layer 10 of the cold functional functional hat 100.

The UV-resistant material may be a material capable of absorbing ultraviolet rays by a polymer such as PVC or a knitted fabric of an inorganic-containing material having an effect of radiating solar rays, and the surface of the outer layer 10 itself may block ultraviolet rays. It can be processed to bring about UV protection effect.

On the other hand, thermal insulation in the sense of blocking heat transfer generally includes not only cold insulation but also the concept of heat retention. Therefore, the air 11 filled in the outer layer 10 may be utilized as a heat retention function in addition to the cold retention function as described in the above-described embodiment.

That is, in winter, the wearer may inject air only into the outer layer 10 without injecting the coolant 21 into the inner layer 20 or inject the air 11 into the inner layer and the outer layer, respectively, to use the 'cold' of the present invention. Functional air cap 100 may be implemented to be transformed into a 'thermal insulation' functional air cap.

As shown, the fiber layer 28 such as the absorbent nonwoven fabric inserted into the inner layer 20 easily absorbs the coolant 21 and reduces the surface area that the coolant 21 contacts with the outside air, thereby reducing the heat transfer surface area. Accordingly, the temperature increase time of the absorbed coolant 21 is increased so that the cooling effect can be maintained for a longer time. Accordingly, the fiber layer 28 may be formed of synthetic fibers such as polyester, acrylic, polypropylene, or other natural fibers such as wool, cotton, and hemp, in addition to the absorbent nonwoven fabric, and may be formed by mixing the synthetic fibers and natural fibers. It is okay.

On the other hand, the fiber layer 28 has a porous structure in which a plurality of vent holes are formed so that mold and the like can be generated and propagated due to residual moisture or the like, and the antimicrobial agent is mixed with the coolant 21. desirable.

Therefore, the air cap 100 is preferably formed by adding the inner shell 27 formed of a material having waterproof or water repellent to the inner surface of the inner layer 20 forming the inner space to increase the wearing comfort. In addition, the endothelium 27 may be attached adjacent to the entire inner surface, or may be attached spaced apart from the inner surface and a predetermined space.

On the other hand, by adding the endothelial 27 having an air layer having a thickness relatively thinner than the thickness of the outer layer 10 instead of the endothelial 27, to increase the heat insulation effect, to extend the cooling time, to prevent the condensation of water vapor to achieve a comfortable wearing feeling. It may be.
