Description

Technical Field

[0001] The utility model relates to a health-care patch, and more particularly to a heating patch capable of applying heat and releasing essential oil. Background Art

[0002] The relevant patent documents about health care patches are as follows:

[0003] CN209048421U heating patch includes: a dressing layer and a heating layer, and generates heat energy through a heating structure of the heating layer. Therefore, when the dressing layer is attached to human skin, the heat energy of the heating layer can heat the dressing layer to achieve a hot compress effect.

[0004] The CN215193943U health care patch comprises a base material and an adhesive coating. The adhesive coating is coated on one surface of the base material. The adhesive coating contains far infrared powder, methylsulfonylmethane, glucosamine and herbal essential oil. The components contained in the adhesive coating are used to relieve the muscle soreness of the user, and the fragrant aroma released by the herbal essential oil is used to exert the deodorizing and antibacterial effects, thereby achieving the substantial benefit of improving the comfort of the patch when applied.

[0005] CN217219619U nano-drug loaded graphene patch includes a base layer and a graphene heating layer; the graphene heating layer includes a plurality of graphene heating components, and the top surface of the graphene heating layer is bonded with an adhesive bonding layer; the top surface of the adhesive bonding layer is bonded with a drug loading layer, and the drug loading layer carries nano-drugs; the base layer is connected with a cover plate, and the cover plate is provided with a hot compress switch; a micro-battery, a micro-controller and a micro-temperature monitor are detachably installed in the base layer. The patch is mainly used to accelerate the diffusion and release of drugs, and can also heat different parts at different time periods.

[0006] The disadvantages of the above-mentioned existing patch are:

[0007] The patch directly mixes essential oils with its adhesive covering layer, which directly contacts the skin and can easily cause skin irritation, allergies and other discomforts.

[0008] When the patch is first used, due to the high concentration of essential oils, it is very irritating and acts quickly, but the essential oils also evaporate quickly, so the effect of the patch is too short-lived.

[0009] The hot compress patch with a heating component uses electronic components, which makes the patch structure too complicated. Utility Model Content

[0010] In order to solve the shortcomings of the existing patch, the utility model provides a heating patch structure.

[0011] The solution of the utility model:

[0012] A heating patch includes a first base fabric, a microcapsule layer, a spacer layer, a heating layer, and a second base fabric;

[0013] The first base fabric is a fabric with a plurality of pores; two surfaces of the first base fabric are respectively defined as a first fabric surface and a second fabric surface;

[0014] The microcapsule layer comprises a glue layer and a plurality of capsule particles; the glue layer is a sheet-shaped glue; the two surfaces of the glue layer are respectively defined as a first glue surface and a second glue surface; the first glue surface is combined with the second fabric surface; the capsule particles are microparticles composed of biological colloids coated with essential oils; the plurality of capsule particles are distributed and mixed in the glue layer;

[0015] The spacing layer is a cloth with a plurality of pores; two surfaces of the spacing layer are respectively defined as a first spacing surface and a second spacing surface; the first spacing surface is combined with the second adhesive surface;

[0016] The heating layer is a sheet structure composed of iron oxide powder, and the two surfaces of the heating layer are respectively defined as a first surface and a second surface, and the first surface is combined with the second spacing surface;

[0017] The second base cloth is a cloth with a plurality of pores; the two surfaces of the second base cloth are respectively defined as a first base surface and a second base surface; the first base surface is combined with the second surface of the heating layer.

[0018] Furthermore, the first fabric surface of the first base fabric is provided with an adhesive layer that can be attached to the skin surface of the user.

[0019] Furthermore, a fixing structure for adhering to the user's skin is arranged on the second base surface of the second base cloth.

[0020] Furthermore, the fixing structure includes a plurality of flexible fixing sheets, and each of the flexible fixing sheets is provided with a covering layer.

[0021] The utility model has the following effects:

[0022] When in use, the first surface of the first base fabric contacts the skin, and air passes through the pores of the second base fabric, causing the heating layer to generate heat when encountering the air, and the heat causes the capsule particles to melt, and the essential oil therein is released and transferred to the user's skin through the first base fabric and its pores.

[0023] The advantage of the heating patch of the utility model is that due to the pores of the second base cloth, a small amount of air is continuously infiltrated into the heating layer, the heating layer is heated up gradually and the warming effect is long-lasting, and the heating patch plays a hot compress role.

[0024] The essential oil is coated in the biological colloid. The essential oil is released only when the biological colloid is melted by heat. The biological colloid controls the release speed of the essential oil.

[0025] The mild heat of the heating layer causes the capsule particles to melt slowly, and the essential oil is released slowly and continuously in small amounts, which can extend the effectiveness of the patch and prevent irritation or discomfort caused by excessive contact of the skin with essential oil at one time.
