[Technical Field]

[0001] The present invention relates to a facial cooling device and a cooling device for cooling a target area on the face. [Background technology]

[0002] For example, a cooling sheet has been developed that a user places on a fevered area to cool it down (see Patent Document 1). This cooling sheet is an eye mask sheet containing cooling gel that is attached to the face, and the heat absorption effect of the cooling gel is used to remove heat. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3240961 Summary of the Invention [Problem to be solved by the invention]

[0004] However, cooling sheets using such cooling gel lose their cooling effect in a short time, making it difficult to maintain the cooling state for a predetermined period of time. On the other hand, while increasing the volume of the cooling gel is considered to ensure a long cooling time, this increases the weight of the cooling sheet, making it difficult to wear it stably, especially on the face.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a facial cooling device and cooling device that can be attached to the face with a lightweight structure, can cool target areas of the face uniformly for a predetermined period of time, and can be reused multiple times. [Means for solving the problem]

[0006] The facial cooling device of the present invention is a facial cooling device for cooling a target area of ​​the face, and comprises a wearing belt worn on the head, at least one canister filled with a hydrogen storage alloy fixed to the wearing belt and placed on the side of the head, a cooling plate fixed to the wearing belt and in contact with the canister, and a thermally conductive sheet fixed to the wearing belt and placed on the target area in contact with the cooling plate, wherein hydrogen gas is released from the canister to cool the cooling plate, and the target area is cooled via the thermally conductive sheet.

[0007] In the facial cooling device, the wearing belt has a two-layer structure of a nylon layer and a urethane layer, and the urethane layer is placed on the face side.

[0008] In the facial cooling device, the canister comprises a metal container filled with a hydrogen storage alloy and a check valve for releasing hydrogen from the metal container.

[0009] In the facial cooling device, the cooling plate is a copper plate.

[0010] In the facial cooling device, the thermally conductive sheet is made of silicone rubber mixed with a thermally conductive filler.

[0011] In the facial cooling device, a replaceable antibacterial film is attached to the surface of the heat conductive sheet that comes into contact with the face.

[0012] The cooling device of the present invention is a cooling device for cooling a target area of ​​a user, and comprises a wearing belt that is worn on the area of ​​the user where the target area is located, at least one canister filled with a hydrogen storage alloy that is fixed to the wearing belt and placed on the side of the head, a cooling plate that is fixed to the wearing belt and in contact with the canister, and a thermally conductive sheet that is fixed to the wearing belt and placed on the target area in contact with the cooling plate, and hydrogen gas is released from the canister to cool the cooling plate, and the target area is cooled via the thermally conductive sheet. [Effects of the Invention]

[0013] The facial cooling device and cooling device of the present invention are configured to release hydrogen from a hydrogen storage alloy filled in a canister to cool a cooling plate, which then cools a target area on the face via a thermally conductive sheet, thereby enabling a lightweight configuration and enabling the target area, such as the face, to be uniformly cooled as desired. Furthermore, the canister can be refilled with hydrogen and reused multiple times, eliminating waste and causing no adverse effects on the environment. [Brief explanation of the drawings]

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of a facial cooling device according to an embodiment of the present invention attached to a face. Fig. 2 is a front view of the facial cooling device according to an embodiment of the present invention in an unfolded state. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2.

[0016] <Description of the Configuration of the Facial Cooling Device 10> The facial cooling device 10 comprises a wearing belt 14, canisters 16a and 16b, a cooling plate 20, and a heat-conductive sheet 22.

[0017] The wearing belt 14 is longer than the outer periphery of the head 12 and has a two-layer structure including a nylon layer 24 and a urethane layer 26, as shown in the cross-sectional view of FIG. 3 . The wearing belt 14 is worn on the head 12. The urethane layer 26 is positioned on the face side when the wearing belt 14 is worn on the head 12. A hook-and-loop fastener 28 is disposed at the end of the urethane layer 26. Meanwhile, the surface of the nylon layer 24 is raised. Therefore, when wearing the wearing belt 14 on the head 12, the hook-and-loop fastener 28 is pressed against the nylon layer 24 to secure the wearing belt 14 to the head 12. The center of the wearing belt 14 is formed with an opening 30 for exposing the eyes and a cutout 32 for exposing the nose.

[0018] The wearing belt 14 has curved portions 34 that are curved like bags at the portions corresponding to both sides of the head when worn on the head 12. A pair of canisters 16a, 16b (hereinafter referred to as "canisters 16") filled with a hydrogen storage alloy are fixed to each curved portion 34 using an adhesive.

[0019] As shown in FIGS. 1 and 4, the canister 16 is disposed on either side of the head and includes a metal container 36 filled with a hydrogen storage alloy, and a nozzle portion 40. The nozzle portion 40 is disposed at the end of the metal container 36 and has a check valve 38. The metal container 36 may be made of aluminum, for example. When the check valve 38 is pressed down in the direction of the arrow, hydrogen gas is released from the hydrogen storage alloy inside the canister 16. The check valve 38 prevents outside air from flowing into the metal container 36, which would deteriorate the function of the hydrogen storage alloy inside.

[0020] 5, the canister 16 may be configured so that the valve member 42 is detachable and releases hydrogen gas when the valve member 42 is pressed down in the direction of the arrow relative to the nozzle portion 40. In this case, it is desirable to connect the valve member 42 to the metal container 36 using a wire 44 to prevent it from being lost.

[0021] The cooling plate 20 is fixed to the mounting belt 14 and is connected and fixed in contact with the metal container 36 of the canister 16. The cooling plate 20 can be made of, for example, a copper plate with high thermal conductivity.

[0022] The thermally conductive sheet 22 is fixed to the wearing belt 14 and placed on the target area in contact with the cooling plate 20. For example, a material obtained by mixing a thermally conductive filler with silicone rubber can be used as the thermally conductive sheet 22. A replaceable antibacterial film 46 is attached to the face side of the thermally conductive sheet 22. Here, the target area refers to the area that the user wishes to cool.

[0023] <Instructions on how to use the facial cooling device 10> The following describes how the user wears the facial cooling device 10 on the head 12. The facial cooling device 10 is worn with the urethane layer 26 of the attachment belt 14 facing the face, with the openings 30 formed in the attachment belt 14 aligned with the eyes. The target area where the thermally conductive sheet 22 of the facial cooling device 10 is placed can be, for example, the eyes and / or the area around them. The end portions of the attachment belt 14 are then connected and secured to the head 12 by pressing the hook-and-loop fasteners 28 at the end portions of the attachment belt 14 against the nylon layer 24 of the attachment belt 14. In this case, the metal cooling plate 20 does not directly contact the target area on the face, but the thermally conductive sheet 22 contacts the target area via the antibacterial film 46, which reduces discomfort and metal allergy concerns. Furthermore, because a replaceable antibacterial film 46 is attached to the thermally conductive sheet 22, there are no hygiene issues, even if the facial cooling device 10 is reused by another user.

[0024] After the facial cooling device 10 is attached to the head 12, the check valve 38 attached to the nozzle 40 of the canister 16 located at the side of the head is pressed down, causing the hydrogen stored in the hydrogen storage alloy in the metal container 36 to gasify and be released to the outside. At this time, the temperature of the metal container 36 drops rapidly due to the release of hydrogen. When the temperature of the metal container 36 drops, this temperature drop is transmitted to the cooling plate 20 in contact with the metal container 36, and the temperature of the thermally conductive sheet 22 arranged along the cooling plate 20 drops. As a result, the target area of ​​the face in contact with the thermally conductive sheet 22 is effectively cooled via the antibacterial film 46. The urethane layer 26 on the face side of the attachment belt 14 prevents condensation from forming even if the temperature of the thermally conductive sheet 22 drops suddenly.

[0025] 6 is an explanatory diagram of an example of a measurement of temperature change over time on the thermally conductive sheet 22 that constitutes the facial cooling device 10. In this example, the temperature immediately before hydrogen was released from the canister 16 was 27.8°C, but once hydrogen release began, the temperature of the surface of the thermally conductive sheet 22 rapidly dropped to around 10.0°C. After that, the cooling state continued for nearly 30 minutes, after which the temperature slowly rose to a temperature close to that before release. It can be seen that the facial cooling device 10 maintains a cooling effect for a predetermined period of time.

[0026] As described above, the facial cooling device 10 for cooling a target area on the face comprises a mounting belt 14 attached to the head 12, a canister 16 filled with a hydrogen storage alloy that is fixed to the mounting belt 14 and placed on the side of the head, a cooling plate 20 that is fixed to the mounting belt 14 and in contact with the canister 16, and a thermally conductive sheet 22 that is fixed to the mounting belt 14 and placed on the target area in contact with the cooling plate 20; hydrogen gas is released from the canister 16 to cool the cooling plate, and the target area is cooled via the thermally conductive sheet 22.

[0027] In the facial cooling device 10, the wearing belt 14 has a two-layer structure of a nylon layer 24 and a urethane layer 26, and the urethane layer 26 is disposed on the face side.

[0028] In the facial cooling device 10, the canister 16 includes a metal container 36 filled with a hydrogen storage alloy and a check valve 38 for releasing hydrogen from the metal container 36.

[0029] In facial cooling device 10, hydrogen is released from the hydrogen storage alloy filled in canister 16 to cool cooling plate 20, which then cools the target area on the face via the thermally conductive sheet. This allows for a lightweight structure and allows for uniform cooling of the target area on the face for a predetermined period of time. Furthermore, canister 16 can be refilled with hydrogen and reused multiple times, eliminating waste and causing no adverse environmental impact. Furthermore, the use of thermally conductive sheet 22 to cool the target area enables uniform heat, rapid cooling, and tracking, allowing the cooling state to be maintained for a predetermined period of time. Furthermore, facial cooling device 10 allows for the ultimate temperature to be freely designed by adjusting the composition and amount of the storage alloy and the heat dissipation properties of the container. Furthermore, it also prevents low-temperature burns and reduces the bulkiness of insulation used to prevent condensation.

[0030] The target area for the facial cooling device 10 described above is the eyes and / or the surrounding area, but it can also be used on the arms, legs, fingers, etc. In such cases, the number of canisters can be changed appropriately, from one or more, depending on the target area. The shape of the facial cooling device 10 can also be changed depending on the target area.

[0031] Therefore, in this case, facial cooling device 10 is used as a cooling device. That is, the cooling device is a cooling device for cooling a target area of ​​a user, and includes a wearing belt worn on the area of ​​the user where the target area is located, at least one canister filled with a hydrogen storage alloy fixed to the wearing belt and placed on the temple of the head, a cooling plate fixed to the wearing belt and in contact with the canister, and a thermally conductive sheet fixed to the wearing belt and placed on the target area in contact with the cooling plate, with hydrogen gas released from the canister to cool the cooling plate and cool the target area via the thermally conductive sheet.

[0032] It should be noted that the present invention is not limited to the above-described embodiment, and various configurations can be adopted without departing from the gist of the present invention.

[0033] For example, in the above embodiment, the canisters 16 are configured as a pair of two, but they may be configured as one or three or more depending on the target site. [Explanation of symbols]
