Description

The present invention relates to an applied technique for daily necessities, and particularly to a phase change heat insulating pack.

Insulation packs (warming the skin) are effective health, physiotherapy, and treatment methods that have been used for a long time. Foot baths, bathtubs, saunas, insulation packs, infrared physiotherapy, etc. born from insulation packs are widely known and accepted. By warming the face, muscle tension can be relieved and inflammation and blood bleeding can be eliminated. The heat insulation pack of the essence of the skin care product can absorb the skin care product locally, achieve the purpose of bringing the skin care product directly to the desired site, and can make the therapeutic effect more direct and more effective.

When packing normally, the temperature of the face and mask is about 25 ° C to 31 ° C. When the temperature of the mask and the temperature of the face are relatively high, pores can be opened, blood circulation is promoted, and the absorption of nutrients in the mask can be enhanced. However, since the mask has a high water content, after packing it on the face, the water evaporates and a large amount of heat is taken away, the temperature of the face drops by about 3 ° C to 5 ° C, the pores shrink, and the essence of the mask Interfere with absorption. Appropriate temperature is very important for facial blood circulation and absorption of essence in the facial mask. Even without a facial mask, warming the face can promote blood circulation in the face, promote metabolism, relieve fatigue, and have a refreshing effect. In addition, by appropriately raising the temperature, the fat on the face can be consumed and the small face effect can be achieved. However, when the room temperature is low (autumn and winter), packing directly on the face not only causes cold irritation, but also worsens the skin care effect of the mask.

Various insulation packs have been developed to increase the temperature and effectiveness of facial masks. For example, an infrared heat insulating pack, a tourmaline mask, an electric mask, a disposable heat insulating pack, and the like. However, the above mask has the following problems.

Since the electric heating mask (TWM384295 etc.) is heated by electricity, it is necessary to conduct electricity during use. In addition, the heating power and temperature must be adjusted by the feedback of the measured temperature. In addition, it is not convenient to conduct electricity during use, and safety cannot be ensured.

The tourmaline mask uses water as a heat storage medium and does not use electricity, so safety can be ensured. However, this type of mask has a narrow applicable temperature range and a short heat retention time, so that the user's evaluation is bad.

Disposable eye masks mostly utilize chemical reactions as a heat source and cannot be used repeatedly. Moreover, eye masks with such a reaction cannot provide a full face pack effect. Further, when such a heat-reactive eye mask is used as a facial mask, the cost becomes high.
In summary, commercial insulation packs require improvements in terms of convenience and safety, and have the problem of being too costly.

In order to solve the above-mentioned problem of the heat insulating pack, the present invention can obtain the optimum effect by using a phase change heat storage material instead of an electric heat source as a direct heat source and packing it in a state where electricity is not conducted. ..

The following disclosures provide different embodiments or examples for practicing different structures of the invention. In order to simplify the disclosure of the present invention, the components and installation of specific embodiments of the present invention will be described below. Further, the present invention repeatedly uses numbers and / or symbols in different embodiments. It is intended to explain the present invention in a concise and clear manner, and does not show the following embodiments and / or examples. The components shown in the drawings are schematics for explaining the invention, regardless of the actual proportions. In order to avoid unnecessary restrictions on the present invention, the description of the well-known techniques and processing processes in the present invention will be omitted below.

FIG. 1 is a schematic structural diagram of a phase change heat insulating pack according to an embodiment of the present invention. The phase change heat insulating pack includes a pack body 10 and a fixing device 20.

The pack body 10 corresponds to the shape of the face, and the nose and mouth are provided with openings for breathing.

The fixing device 20 is for fixing the pack body 10 to the face, and is fixed to the pack body 10. The fixing device 20 has a band structure fixed to both ends of the pack body 10, and can be provided with a velcro (registered trademark), a buckle, or the like for fixing to the ends of the band structure. It may also be an integrated elastic band for hanging on the user's head. Further, it is preferable to increase the weight of the phase change heat insulating pack from 100 g to 300 g. By doing so, the completeness of the structure of the phase change heat insulating pack can be ensured, and the burden on the user at the time of mounting can be reduced.

As shown in FIG. 2, the pack main body 10 includes a housing 11, a heat insulating layer 12, a heat storage layer 14, a transition layer 15, and a surface layer 16 in this order from the outside to the inside.

The appearance of the pack body 10 is mainly determined by the housing 11 and has a protective function for protecting other structural layers of the pack body 10.

The heat insulating layer 12 can reduce the heat loss of the pack body 10 during heating and use, extend the heat retention time, and enhance the effect of using the phase change heat retention pack.

The heat storage layer 14 is a phase change material having a phase change point of 38 ° C to 80 ° C. Preferably, the heat storage layer 14 is a phase change material having a phase change point of 50 ° C to 60 ° C. The phase change material can quickly absorb and store heat. The heat storage layer 14 is the core layer of the phase change heat insulating pack. The phase change point of the phase change material corresponds to the thickness of the transition layer 15. If the thickness of the transition layer 15 is increased or the thermal conductivity is decreased, the heat transfer resistance of the heat storage layer 14 to the face is increased, and it is necessary to increase the temperature difference. That is, it is necessary to raise the phase change temperature point to increase the amount of heat storage. In practical applications, the required facial mask temperature is 38 ° C to 41 ° C. However, since the transition layer 15 has a predetermined thickness (for example, 3 mm), the phase change point of the phase change material is preferably 55 ° C. When the thickness of the transition layer 15 changes, the phase transition temperature point also needs to be adjusted according to the temperature of the face.

The phase change insulation pack can be heated in a microwave oven. When heating in a microwave oven, the phase change material does not need to retain its shape, but it must have the function of absorbing the heat of microwaves in the microwave oven. When heating in a microwave oven, the heating time is controlled between 20 and 40 seconds. When it is necessary to heat in a microwave oven, the phase change heat insulating pack is free from components having a higher ability to absorb microwave heat than the heat storage layer 14, such as a heating sheet containing metal, a connecting wire, and the like.

The transition layer 15 is made of a soft and porous material. Preferably, the transition layer 15 uses a sponge material having a thickness of 1 mm to 7 mm. More preferably, 3 mm to 5 mm is used. More preferably, a sponge material having a thickness of 3 mm is used. Although the sponge itself is a porous material, additional through holes may be added in the sponge in order to enhance heat exchangeability and air permeability.

In order to enhance the skin care effect, a skin care oil and / or a beauty ingredient such as Chinese medicine (for example, byakushi, pearl powder) can be added to the transition layer 15.

Further, in order to increase the efficiency of the phase change heat insulating pack, a massage device may be added between the transition layer 15 and the surface layer 16. During use, you can massage while keeping warm to enhance the effect.

The amount of heat of the heat storage layer 14 is transferred to the surface layer 16 and the face pack through the through holes of the transition layer 15. The contour and thickness of the transition layer 15 correspond to the contour of the face and its flexibility and elasticity ensure that it is suitable for different face types. Other functional ingredients, such as Chinese herbal ingredients having a health care function, can be added to the transition layer 15. Such components can be transmitted directly to the surface layer 16 so that the face can be masked directly. Alternatively, it can be combined with the effect of the facial mask to improve the effect of using the facial mask.

In addition, such a component having a health care effect can be installed between the transition layer 15 and the surface layer 16 to form a single functional layer.

The cloth of the surface layer 16 easily adheres to the facial mask, prevents moisture on the facial mask from infiltrating into the transition layer 15, and is clean and easy to wash. Preferably, the transition layer 15 and the surface layer 16 are integrally formed in order to reduce the cost. For example, the transition layer 15 uses a sponge material. Wrap the sponge with a cloth and silicone to form a soft pad. One side uses a waterproof and oil-proof silicone material for masks, and the other side is a porous and breathable cloth that is not used as a facial mask. To use.
Further, the surface layer 16 or the integrated surface layer and transition layer 15 must meet the conditions of easy cleaning and easy replacement.

Preferably, the phase change thermal insulation pack further comprises a heating layer 13, the heating layer 13 being disposed between the heat storage layer 14 and the transition layer 15, or between the heat insulating layer and the heat storage layer, or heat storage. It is placed between the two heat storage materials in layer 14. Preferably, as the heat generating layer, a PET (polyethylene terephthalate) heating sheet and / or a PI (polyimide, polyimide) heating sheet is used. The internal temperature of the heating sheet is well-balanced, and the effect of the face mask is good. A heating wire is provided in the heating layer 13, and the layout of the heating wire corresponds to the layout of the phase change material. The heating layer 13 changes electrical energy into heat energy via a heating wire and stores it in the heat storage layer. Moreover, after turning off the electricity, the heat energy can be released. Preferably, the heating layer is heated at a voltage of 36 V or less to more reliably ensure the safety of use. For example, the heating layer 13 is overheated at a low voltage of 24V or 12V.

When heating by the electric heating method, the phase change material needs to be processed into a standard material and mixed with a component having high thermal conductivity. Usually, powders such as graphene, expanded graphite, carbon fiber, alumina, silicon nitride, etc., or short-cut fibers, high thermal conductive fillers, bubble foams of copper and other high thermal conductive metals, meshes, etc. are used. For example, graphene and expanded graphite with a ratio of 3% to 20%, preferably 5% to 15% are used. By blending a component having a high thermal conductivity, the rate of heating and heat absorption of the heat generating layer 13 can be increased, and the effect of using the phase change heat insulating pack is improved.

When heated electrically, the phase change material needs to form a skeleton with other materials to retain its shape, which guarantees a solid phase change in appearance, so that the liquid transfer phenomenon has a heating guarantee effect and use. Safety can be ensured. Examples of the skeleton forming and retaining shape include oil-absorbing resin, oil-absorbing rubber, inorganic adsorbent, for example, POE (polyolefin elastomer), molecular sieve, activated carbon and the like. Preferably, HDPE (High Density Polyethylene) is used to form a skeleton and retain its shape.

Preferably, the phase change insulation pack further comprises a control device. The control device includes a power supply, a transformer and a timer. Alternatively, the transformer, timer and / or other component may be combined with an integrated circuit board. In actual applications, it is preferable to use a combination of a power supply and an integrated circuit board. The control device heats the heating layer and is used to control the heating process. Further, the heat generating layer 13 is provided with a temperature limiter. The temperature limiter ensures that the temperature of the phase change insulation pack is not too high, thereby improving safety in use.

Preferably, when heating using electricity, a thermocouple for temperature measurement is installed on one side of the surface layer 16, and the temperature of the phase change heat insulating pack is recorded in real time using the thermocouple for temperature measurement. Preferably, the phase change insulation pack further comprises a display device that displays the temperature in real time. The display device may be an LED display. Preferably, the phase change thermal insulation pack further comprises a transmission device that transmits the temperature data measured by the thermocouple in real time. The receiving device may be a mobile terminal, a PC, a cloud storage device, or the like.

The phase change thermal insulation pack provided by the present invention can overheat the mask, thereby enhancing the effect of using the mask. In addition, the phase change heat insulating pack provided by the present invention can be used even without a facial mask. If you don't have a facial mask, you can simply heat the phase change insulation pack and then apply it to your face. In order to achieve the face thinning effect, it is necessary to raise the phase change point and raise the temperature of the phase change heat insulation pack. To improve comfort, the surface layer 16 can be removed and the transition layer 15 can be made of a hydrophilic material to facilitate sweat absorption and ventilation.

When using a microwave oven as an indirect heat source, the phase change insulation pack provided by the present invention can be heated in the microwave oven for 20-40 seconds. If provided with an electric heating layer, the power is turned on, heated for 2 to 10 minutes (preferably 3 to 5 minutes) at a time, and then automatically turned off. In this process, the unopened facial mask can be heated at the same time. When packing, either pack according to the usual procedure, or spread the facial mask on the cloth on the surface layer of the pack body, and then wear the phase change insulation pack on the face. Further, the phase change heat insulating pack provided by the present invention can be used for various purposes. For example, before packing a facial mask, the phase change heat insulating pack is first applied to the face to widen the pores of the face. Detox, then wash face and pack facial mask. Subsequently, the facial mask is heated using the phase change heat insulating pack to pack the face. This achieves a good effect.

As shown in FIG. 3, by using the phase change heat insulating pack provided by the present invention, the temperature at the time of packing can be appropriately increased, the pores are widened, and the absorption of the skin care product of the facial mask is promoted. Can be done. In addition, by maintaining a temperature suitable for the temperature of the face, it is possible to improve the comfort of use by the user.

As shown in FIG. 4, in the process of packing, the phase change heat insulating pack can be kept within an appropriate temperature range for a long time.

The phase change mask provided by the present invention has accurate and reasonable temperature control, safe use, reusability and low cost, and exhibits various cosmetic effects such as face thinning effect.
