Description

Phase change thermal mask

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a field of application in daily necessities, and more specifically, to a phase change thermal mask.

Hot skin (skin heating) is an old and effective way to treat health, physical therapy, and even illness. Foot baths, baths, saunas, hot tubs, and infrared physical therapies, which are derived from warm skin, are already known to many people and are recognized by many people. Applying heat to the face area can relieve muscle tension and promote inflammation and hemorrhage. The warming of skin care products can also be intended to absorb skin care products locally and reach the site directly, and the treatment effect is more direct and more effective.

Generally, when the mask pack is attached, the temperature of the face and the mask pack is about 25 ° C to 31 ° C. When the temperature and the face temperature of the mask pack are relatively high, the opening of the pores and the blood circulation are promoted, thereby increasing the absorption effect of the mask pack essence. However, since the mask pack has a large amount of moisture, it absorbs a large amount of heat when moisture evaporates after adhering to the face, so that the temperature of the face portion is lowered by 3 ° C. to 5 ° C. and the pores contract to absorb the essence of the mask pack It is disadvantageous. A suitable temperature is very important for circulation of the face area and absorption of the essence inside the mask pack. Even if there is no mask pack, raising the temperature of the face area accelerates blood circulation on the face and promotes metabolism, thereby relieving fatigue and making the patient feel better. Also, if the temperature is increased moderately, the consumption of the face fat is accelerated, and the effect of slimming the face can be obtained. However, when the room temperature is low (autumn or winter), attaching the mask pack directly to the face not only gives a cold stimulus, but also the skin care effect of the mask pack is poor.

In order to increase the temperature of the mask pack and obtain a better facial pack effect, various thermal masks such as an infrared thermal mask, a tourmaline mask, an electric warm mask, and a disposable thermal mask are currently on the market. However, the masks each have some disadvantages.

Electric heat masks (eg TWM384295, etc.) all generate electric heat and must be continuously energized during use, and the heat output and temperature must be regulated through the feedback of the temperature meter. Due to the specificity and importance of the facial area, it is difficult to guarantee not only inconvenience but also absolute safety if the user needs to keep the electricity in use.

The tourmaline mask uses water as a heat storage medium and can be used without electricity to ensure safety. However, since the face area is very sensitive to temperature, these masks have a narrow temperature range, a short warm-up time, and a poor user experience.

Most disposable eye masks use chemical reaction heat effect as a heat source and can not be used repeatedly. Eye masks also can not provide effective warming of the face area. If such a heat-reactive eye mask is manufactured from a mask pack, the cost may rise vertically, which is disadvantageous for widespread use.

Taken together, the hot mask products on the market need to be improved in terms of both convenience and safety, and the cost is too high.

In order to solve the problem existing in the conventional warming mask, the present invention uses a phase change heat storage material as a direct heat source of the face portion in place of the heating wire, thereby attaching the mask pack or attaching it to the face So that an optimum effect can be obtained.

The following disclosure provides many different embodiments or examples for implementing the different structures of the present invention. In order to simplify the disclosure of the present invention, the following is a description of the absence and installation of specific examples. In addition, the present invention can also refer to numbers and / or characters in duplicate among different examples. Such duplication is for the sake of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or installations. It should be noted that the members shown in the accompanying drawings are not made to scale. The present invention has been described so that it does not unnecessarily restrict the present invention and the description of known assemblies, processing techniques and processes.

Referring to FIG. 1, FIG. 1 is a structural view of a specific embodiment of a phase change insulating mask provided by the present invention.

The mask body 10 conforms to the shape of the face portion, and an opening is preliminarily provided in the nostrils and mouths to facilitate breathing.

The fixing device 20 is installed in the mask body 10 to fix the mask body 10 to the face portion. The fixing device 20 has a belt-like structure that can be fixed to both ends of the mask body 10, and a velcro, a knot, and the like for fixing are provided on the end of the belt-like structure. It may also be an integrated elastic band that can be worn directly on the user's head. The weight of the phase change thermal insulation mask is preferably maintained between 100 g and 300 g. By doing so, not only can the phase change mask structure be completely ensured, but also the burden on the wearer when worn can be reduced.

Referring to FIG. 2, the mask body 10 includes a housing 11, a heat fault layer 12, a heat storage layer 14, a transition layer 15, and a face layer 16 sequentially from the outside to the inside.

The outer appearance of the mask body 10 is determined mainly by the housing 11 having a protective function for protecting the remaining structural layers of the mask body 10. [

 The heat fault layer 12 serves to reduce the heat energy loss of the mask body 10 during heating and use, extend the keeping time, and reinforce the use effect of the phase change thermal insulating mask.

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 to 60 ° C. The phase change material can quickly absorb and store thermal energy, and the heat storage layer 14 is a core layer of the phase change thermal insulation mask. The phase change point of the phase change material coincides with the thickness of the transition layer 15. When the thickness of the transition layer 15 increases or the thermal conductivity decreases, the heat resistance of the heat storage layer 14 to transfer heat to the face or mask pack increases, and it is necessary to increase the temperature difference, Increase the temperature point and increase the heat capacity. In practical applications, although the temperature of the mask pack required for the face region is 38 ° C to 41 ° C, the transition layer 15 has a constant thickness (eg, 3 mm)

Lt; 0 > C. When changing the thickness of the transition layer 15, the phase change temperature point also needs to be adjusted according to the corresponding value so as to match the face temperature.

The phase change thermal mask may be heated through a microwave oven. When heated by a microwave oven, the phase change material may not maintain its shape, but the heat storage layer 14 material must have a functional ingredient that absorbs microwaves. When heating with a microwave oven, the heating time is controlled to be between 20 s and 40 s. It should be noted that when the microwave oven is to be heated, the phase change insulating mask should not include a member that absorbs microwaves more easily than the heat storage layer 14, for example, a metal heating plate, a connecting wire, and the like.

The transition layer 15 is made of a flexible porous material. Preferably, the transition layer 15 is a sponge material having a thickness of 1 mm to 7 mm, preferably 3 mm to 5 mm, and more preferably a sponge material having a thickness of 3 mm. Although the sponge itself is a porous material, some additional apertures may be added between the sponges to facilitate heat exchange and ventilation.

Beauty health ingredients such as skin care essence and / or herbal medicines (for example, albicans, pearl powder, etc.) can be added to the transition layer 15 to place beauty and skin care effects.

In addition, a massage device may be added between the transition layer 15 and the face layer 16 in order to enhance the effectiveness of the phase change thermal mask. During the use process, The effect can be enhanced.

 Thermal energy of the heat storage layer 14 is transferred to the face layer 16 and the mask pack through the hole passage of the transition layer 15. The morphology and thickness of the transition layer 15 are matched to the outline of the facial region, and the flexibility and compressibility of the morphology allows the phase change thermal mask to be applied to various facial models. Other functional ingredients, such as herbal ingredients with some health function, may be added to the transition layer 15, which may be delivered directly to the face layer 16 and used as a face pack; Or in combination with the function of the mask pack, the effect of using the mask pack can be enhanced.

In addition, components with such health benefits can be independently provided between the transition layer 15 and the face layer 16 by forming one functional layer.

The fabric of the face layer 16 is easily adhered to the mask pack to prevent moisture on the mask pack from entering the transfer layer 15 and also to facilitate cleaning and cleaning. In order to reduce the cost, the transition layer 15 and the face layer 16 are preferably integrally formed. For example, the transition layer 15 employs a sponge material. A soft pad is formed by wrapping a sponge with a fabric and silicone, and one side is used for attaching a mask pack using a waterproof and oil repellent silicone material; The other side uses a fabric that maintains the air permeability of the pores, and is used for the face padding without the mask pack.

In addition, the face layer 16 or the integrated face layer and the transition layer 15 must both satisfy the detachable condition to facilitate cleaning and replacement.

Preferably, the phase change thermal mask further comprises a heating layer 13, and the heating layer 13 is disposed between the heat storage layer 14 and the transition layer 15 or between the heating layer 14 13 are provided between the two-layer heat storage material of the heat storage layer 14. Preferably, the heating layer uses a PET (polyethyleneterephthalate) heating film and / or a PI (polyimide) heating film. The temperature field inside the heating film is balanced, and the effect of padding on the face is excellent. The heating layer (13) is provided with heating wires, and the arrangement of the heating wires is matched with the arrangement of the phase change material. The heating layer 13 converts electric energy into heat energy through a heat line and stores the heat energy in the heat storage layer, and also dissipates thermal energy after the electricity is cut off. Preferably, the heating layer is heated to a voltage of 36 V or less in order to further ensure safety of use, and the heating layer 13 is heated by using a low voltage of, for example, 24 V, 12 V.

When heated by an electric heating method, the phase change material needs to be processed into a molding material, and a component having a high thermal conductivity must be mixed. In general, open cell foams and meshes of metals with high thermal conductivity, such as graphene, expanded graphite, carbon fiber, aluminum oxide, silicon nitride, etc., or high thermal conductivity fillers of short cut fiber type are adopted. For example, the ratio of graphite to expanded graphite is 3% to 20%, preferably 5% to 15%. Addition of a component having a high thermal conductivity can increase the heating and endothermic speed of the heating layer 13, thereby improving the use efficiency of the phase change insulating mask.

When heated in an electric furnace, the phase change material must maintain its shape by using other materials as a frame so as to ensure a phase change of the solid-solid at the time of appearance and to prevent the transition of the liquid. The frame shape retention can be carried out using inorganic adsorbing materials such as oil absorbing resin, oil absorbing rubber, POE (polyolefin elastomer), molecular sieve, activated carbon, etc. and it can be used as HDPE (High Density Polyethylene) It is most desirable to maintain the shape of the frame.

Preferably, the phase change thermal mask further comprises a control device. The control device includes a power source, a transformer, and a timer. Or the transformer, timer, and / or other components may be combined into an integrated circuit substrate. In practical applications it is desirable to employ a combination of power supply and integrated circuit board. The control device is for heating the heating layer and for controlling the heating process. In addition, the heating layer 13 includes a temperature limiter. The temperature limiter ensures that the temperature of the phase change thermal mask does not become too high, thus increasing the safety of use.

Preferably, when electric furnace is heated, a temperature measuring thermocouple is installed on one side of the face layer (16). The temperature measuring thermocouple is for recording the temperature of the phase change insulating mask in real time. Preferably, the phase change thermal mask includes a display device for displaying temperature in real time. The display device may be an LED screen. Preferably, the phase change thermal mask further comprises a transfer device for transferring temperature data measured by a temperature measurement 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 mask provided by the present invention not only can enhance the effect of using the mask pack by heating the mask pack, but also can be used without the mask pack. In the absence of a mask pack, warming of the face can be performed only by heating the phase change warming mask. In order to obtain the face slimming effect, the phase change point may be further raised to raise the temperature of the phase change thermal insulation mask. In order to enhance the comfort, the face layer 16 is removed, and the transition layer 15 is advantageous in sweat absorption and breathability when a hydrophilic material is used.

In the phase change insulating mask provided in the present invention, when the microwave is used as an indirect heat source, it may be heated in a microwave oven for 20 to 40 seconds. When the electric heating layer is provided, the electric power is automatically turned off after being heated for 2 to 10 minutes (preferably 3 to 5 minutes) at a time when the electric power is turned on. In this process, unmasked mask packs can be heated simultaneously. Attach the mask pack to the face according to the general procedure for the face pack, or place the mask pack on the face layer of the mask body, and then wear a phase change thermal mask on the face. In addition, the phase change insulating mask provided by the present invention has various uses. For example, before attaching the mask pack, the present phase change warming mask is worn on the face for a short period of time to enlarge the pores to release the toxin, wash it, and attach the mask pack, , It is possible to obtain the optimum effect finally.

As shown in FIG. 3, the phase change thermal mask provided by the present invention can raise the temperature at the time of attaching the mask pack so that the pores are opened, and absorption of nutrients of the mask pack is promoted. At the same time, the temperature suitable for the face part significantly raises the comfort feeling of the user.

4, in the face pack process, the temperature of the phase change insulating mask can be maintained within a suitable temperature range for a long time.

The phase change thermal mask provided by the present invention can provide various beauty and face slimming effects with temperature control being precise and reasonable, safe to use, reusable, low cost, and various.
