Description

Phase-change warm-keeping mask

Technical Field

The utility model belongs to the technical field of daily necessities are used, specifically speaking relates to a phase transition heat preservation face guard.

Background

Hot compress (heating the skin) is an old and effective method of health care, physical therapy, and even treatment. Foot bath, bathing, sauna, hot compress, infrared physiotherapy and the like derived from hot compress are widely known and widely accepted. The hot compress on the face can relieve muscle tension, promote inflammation and eliminate blood stasis. The hot compress of the skin care product can also lead the skin care product to achieve the purpose of directly reaching the required position through local absorption, thus leading the curative effect to be more direct and effective.

Typically, when applying the mask, the face and face mask temperatures are about 25 ℃ to about 31 ℃. When the temperature of the mask and the temperature of the face are higher, pores can be promoted to be opened, blood circulation is accelerated, and the effect of absorbing essence of the mask is improved. However, because the facial mask has a large water content, after the facial mask is applied to the face, a large amount of heat can be taken away when the water is volatilized, so that the temperature of the face is reduced by 3-5 ℃, pores are shrunk, and the essence absorption in the facial mask is not facilitated. The proper temperature is critical to the blood circulation of the face and the absorption of the essence inside the mask. Even if the facial mask is not used, if the facial temperature is increased, the facial mask can also accelerate the blood circulation of the face and promote the metabolism, thereby further playing the roles of relieving fatigue and refreshing; in addition, the temperature is moderately raised, the face fat consumption can be accelerated, and the face slimming effect is achieved. When the room temperature is low (autumn and winter), the mask is directly applied to the face, so that the face is stimulated by cold, and the skin care effect of the mask is not good.

In order to raise the temperature of the mask in order to achieve a better application, a number of heated masks are currently on the market, for example: infrared heating face mask, tourmaline face mask, electric heating face mask, disposable heating face mask, etc. However, each of the above-mentioned masks has certain drawbacks.

Electric heating face masks (such as TWM 384295) use electricity for heating, need to be electrified all the time when in use, and then adjust heating power and temperature through temperature measurement feedback. Due to the particularity and importance of the face, if the power is plugged all the time during use, the operation is inconvenient, and absolute safety cannot be guaranteed.

The tourmaline mask uses water as a heat storage medium, can be used without electricity, and can ensure safety. But because the face is very sensitive to the temperature, the mask has the advantages of narrow proper temperature range, short heat preservation time and poor user experience.

The disposable eyeshade mostly adopts the heat effect of chemical reaction as a heat source and cannot be reused; and the eye mask does not provide effective hot compress to the face. If the thermal reaction eye mask is made into a mask, the cost of the thermal reaction eye mask is increased linearly, and the thermal reaction eye mask is not beneficial to popularization and use.

In conclusion, hot compress mask products in the market need to be improved in the aspects of convenience and safety and are too high in cost.

Detailed Description

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and processes are omitted so as to not unnecessarily limit the invention.

Referring to fig. 1, fig. 1 is a schematic structural view of a specific embodiment of a phase change thermal mask according to the present invention. This cold-proof face guard of phase transition includes: a mask body 10 and a fastening device 20.

The mask body 10 is matched with the shape of the face, and openings are reserved in nostrils and the mouth, so that breathing is facilitated.

The fixing device 20 is disposed on the mask body 10, and is used for fixing the mask body 10 to the face. The fixing device 20 can be fixed to the belt-shaped structures at the two ends of the mask body 10, and a hook and loop fastener, etc. is arranged at the tail of the belt-shaped structure for fixing; or an integrated elastic band which is directly sleeved on the head of the user. Preferably, the weight of the phase-change thermal mask is kept between 100g and 300 g. Therefore, the phase-change thermal mask can be ensured to have a complete structure, and the burden of a user when the phase-change thermal mask is worn can be reduced.

Referring to fig. 2, the mask body 10 includes, in order from outside to inside: the heat-insulating layer comprises a shell 11, a heat-insulating layer 12, a heat storage layer 14, a transition layer 15 and a surface layer 16.

The appearance of the mask body 10 is mainly determined by the shell 11, and the mask body has a protection function to protect the rest of the structural layers of the mask body 10.

The heat insulation layer 12 is used for reducing heat loss of the mask body 10 during heating and use, prolonging the heat preservation time and enhancing the use effect of the phase-change heat insulation mask.

The heat storage layer 14 is a phase change material with a phase change point of 38-80 ℃, and the phase change material is packaged in cloth or a plastic film bag. Preferably, the heat storage layer 14 is a phase change material having a phase change point of 50 to 60 ℃. The phase-change material can quickly absorb and store heat. The heat storage layer 14 is the core layer of the phase-change thermal mask. The phase change point of the phase change material is matched to the thickness of the transition layer 15. When the thickness of the transition layer 15 is increased or the thermal conductivity is decreased, the thermal resistance of the heat storage layer 14 to the face or the mask is increased, and it is necessary to increase the temperature difference, that is, to increase the phase transition temperature point and to increase the heat storage amount. In practice, although the temperature of the mask required for the face is 38 ℃ to 41 ℃, since the transition layer 15 has a certain thickness (e.g. 3mm), it is preferable that the phase change point of the phase change material is 55 ℃. If the thickness of the transition layer 15 is changed, the phase transition temperature point also needs to be adjusted accordingly so that it is adapted to the face temperature.

The phase-change heat-insulating mask can be heated by a microwave oven, and when the phase-change heat-insulating mask is heated by the microwave oven, the phase-change material can be of a non-dimensional type, but the material of the heat storage layer 14 must have a functional component for absorbing microwaves. When the microwave oven is used for heating, the heating time is controlled between 20s and 40 s. It should be noted that if microwave heating is required, components that absorb microwaves more easily than the heat storage layer 14, such as metal-containing heating sheets, connecting wires, and the like, must not be included in the phase-change thermal mask.

The transition layer 15 is made of a flexible porous material. Preferably, the transition layer 15 is made of sponge material with a thickness of 1mm to 7mm, preferably 3mm to 5 mm. More preferably, a sponge material with a thickness of 3mm is selected. Although the sponge is made of porous materials, in order to facilitate heat exchange and air exchange, a plurality of through holes can be additionally arranged between the sponges.

In order to improve the effects of beauty and skin care, the transition layer 15 may be added with skin care essential oil and/or Chinese medicinal materials (such as radix Paeoniae alba, pearl powder, etc.).

Furthermore, in order to increase the efficacy of the phase-change thermal insulation mask, a massage device can be added between the transition layer 15 and the surface layer 16. When in use, the utility model can be applied with hot compress and massaged and vibrated at the same time, thereby improving the efficacy.

The heat of the heat storage layer 14 is transferred to the surface layer 16 and the surface film through the pores of the transition layer 15. The profile and thickness of the transition layer 15 are matched with the facial contour, and the flexible and compressible characteristics of the transition layer can ensure that the phase-change thermal mask is suitable for various facial shapes. Other functional components, such as certain traditional Chinese medicine components with health care functions, can be added into the transition layer 15, and can be directly transmitted to the surface layer 16 and directly applied to face application; or the composition is combined with the efficacy of the facial mask to improve the using effect of the facial mask.

In addition, these components with health-care effect can also be independently used as a functional layer and arranged between the transition layer 15 and the surface layer 16.

The cloth of the surface layer 16 is easy to be attached to the mask, so that water on the mask is prevented from entering the transition layer 15, and the mask is easy to clean. Preferably, the transition layer 15 and the face layer 16 are integrally formed for cost reduction. The transition layer 15 is exemplified by a sponge material. Wrapping sponge with cloth and silica gel to form a soft pad, and applying waterproof and oilproof face pack on one side of the soft pad; the other side adopts cloth, keeps porous and breathable, and is used without a mask for hot face.

In addition, the surface layer 16 or the integrated surface layer and the transition layer 15 need to meet the detachable condition, so that the cleaning and the replacement are convenient.

Preferably, the phase-change thermal mask further comprises a heat-producing layer 13, wherein the heat-producing layer 13 is arranged between the heat-storing layer 14 and the transition layer 15; alternatively, the heat-producing layer 13 is interposed between two heat storage materials of the heat storage layer 14. Preferably, the heating layer adopts a PET heating sheet and/or a PI heating sheet. The heating plate has balanced internal temperature field and good face applying effect. The heat production layer 13 is provided with heating wires, and the layout of the heating wires is matched with that of the phase-change material. The heat generating layer 13 converts electric energy into heat energy through the heating wire, and releases the heat energy after power failure. Preferably, for better guarantee of using safety, the heat production layer is heated by a voltage not higher than 36V, for example, the heat production layer 13 is heated by a low voltage of 24V or 12V.

When the electric heating mode is adopted for heating, the phase-change material needs to be processed into a shaping material, and a high-heat-conductivity component is blended. High thermal conductivity fillers in the form of powders or chopped fibers of graphene, expanded graphite, carbon fibers, alumina, silicon nitride, etc., open-cell foams, meshes, etc., of high thermal conductivity metals such as copper, etc., are generally used. By way of example, graphene and expanded graphite are used in a proportion of 3% to 20%, preferably 5% to 15%. The high-thermal-conductivity component is blended, so that the heating and heat absorption speed of the heat production layer 13 can be increased, and the service efficiency of the phase-change thermal mask is improved.

When the electric heating is used, other materials are needed to be used as the skeleton dimensional type of the phase-change material, so that solid-solid phase change is ensured during appearance, the liquid migration phenomenon is avoided, and the heating effect and the use safety are effectively guaranteed. The skeleton dimension type can be made of oil absorption resin, oil absorption rubber, inorganic adsorption materials and the like, such as: POE, molecular sieve, active carbon and the like. Most preferably, HDPE (High density polyethylene) is used for the skeletal profiling.

Preferably, the phase-change heat-preservation mask further comprises a control device; the control device includes: a power supply, a transformer and a timer. Alternatively, the transformer, timer and/or other components may be combined into an integrated circuit board. In practice, a combination of power supply and integrated circuit board is preferably used. The control device is used for heating the heating layer and controlling the heating process. Further, the heat producing layer 13 includes a temperature limiter. The temperature limiter can ensure that the temperature of the phase-change heat-preservation mask is not too high, and the use safety of the phase-change heat-preservation mask is improved.

Preferably, when electric heating is adopted, a temperature thermocouple is arranged on one side of the surface layer 16; and the temperature thermocouple is used for recording the temperature of the phase change heat-insulating mask in real time. Preferably, the phase-change thermal mask comprises a display device for displaying the temperature in real time. The display device may be an LED display screen. Preferably, the phase-change thermal mask further comprises a transmission device for transmitting the temperature data measured by the temperature thermocouple in real time. The receiving device may be a mobile terminal, a PC, a cloud storage device, or the like.
