Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of human health protector, especially to a flexible heating support sheet. BACKGROUND

[0002] With people's increasing attention to health and sports safety, the protector has become an important tool to protect the key parts of the human body from injury, usually including neck protection, shoulder protection, elbow protection, wrist protection, waist protection, knee protection, waist protection, etc., which are widely used in sports, daily activities and medical rehabilitation fields, and in order to effectively provide support and protection, the support sheet is an indispensable key component in the design of these protectors, which can reduce the impact of movement or external force on joints and muscles, thereby preventing or reducing injury, and the support sheet in most protectors on the market currently has a single function and does not have a heating function, so heating sheets need to be additionally added to achieve the heating effect, which increases the complexity of the structure design of the protector and the manufacturing cost, and needs to be solved urgently. SUMMARY

[0003] In view of the above deficiencies in the prior art, the present application provides a flexible heating support sheet.

[0004] The above invention purpose of the present application is realized by the following technical scheme:

[0005] The support sheet body comprises a heat storage surface layer, a heating layer, a support framework layer and a heat insulation layer from top to bottom, the heat storage surface layer is made of polyethylene fiber, the heating layer comprises infrared absorber and ultraviolet light reflector, the support framework layer is made of hollow microbead layer, and the heat insulation layer is made of porous silicon material.

[0006] By adopting the above technical scheme, the polyethylene fiber has a good heat conduction rate, and the structure has a plurality of concave points for heat aggregation, which is used as a heat storage surface layer. When it is attached to the human body, it can quickly absorb the heat of the heat-absorbing layer and conduct the heat to the human body. Moreover, it has high mechanical strength and can withstand external force and pressure when attached to the human body, thereby ensuring the durability of the heat storage effect. By adding the infrared absorber and the ultraviolet light emitter, the heat-absorbing layer can continuously absorb the infrared radiation emitted by the human body when it is in close contact with the human body. After the superposition and oscillation process, new infrared radiation is generated and continuously fed back to the human body, thereby completing the heating and maintaining a relatively stable temperature. At the same time, the far infrared radiation penetrates into the human body, which can promote blood vessel dilation, blood circulation and other health effects. The ultraviolet light reflector can effectively reflect the ultraviolet light harmful to the human body, thereby reducing the harm to the human body. The spherical hollow microsphere structure in the hollow microsphere layer is densely arranged and has a plurality of contact points and can be arbitrarily bent. As a support skeleton layer, the plurality of contact points can meet the compression strength when attached to the human body, and the arbitrarily bendable characteristic can provide flexible support to the human body, thereby improving the comfort of the human body when wearing. The porous silicon has high porosity, making it difficult for heat to pass through. As a heat insulation layer, it can exhibit excellent heat insulation performance. Moreover, the porous silicon has the characteristics of lightweight, which can reduce the weight of the product and is suitable for use in close contact with the human body. The above four-layer structure design can provide flexible support to the human body while improving its heating and warming performance. Without the need to additionally add heating sheets in the protective gear, the design of the protective gear is simplified, the manufacturing cost is reduced, and the practicality and comfort of the support sheet are improved.

[0007] In a preferred example, the hollow microsphere layer is made of hollow microspheres and a slightly foamed adhesive.

[0008] By adopting the above technical scheme, the hollow microspheres and the adhesive form a light and strong support network that can disperse pressure and provide stable support. Moreover, it is convenient to stably connect the support skeleton layer between the heat storage surface layer and the heat insulation layer. At the same time, through slight foaming, the adhesive can form a micro-bubble structure inside, making the support skeleton layer more lightweight and elastic, thereby improving the comfort of the human body when wearing.

[0009] In a preferred example, the heat insulation layer is formed by slightly foaming the porous silicon material into a multi-network structure.

[0010] By adopting the above technical scheme, the heat insulation performance of the porous silicon is combined with the micro-bubble structure formed by slight foaming, which can further slow down the heat transfer efficiency and achieve efficient heat insulation.

[0011] In a preferred example, the polyethylene fiber used in the heat storage surface layer has a thickness of 0.1-0.5 mm, the heating layer has a thickness of 0.01-0.05 mm, the hollow microsphere layer used in the support framework layer has a thickness of 0.5-2 mm, the porous silicon material used in the heat insulation layer has a thickness of 0.5-0.8 mm, and the total thickness of the heat storage surface layer, the heating layer, the support framework layer and the heat insulation layer is not more than 3 mm.

[0012] By using the above technical solution, the heat storage surface layer, the heating layer, the support framework layer and the heat insulation layer are stacked in the thickness range, which can complete the complementary structure design to provide flexible support to the human body and improve the heating and warming performance.

[0013] In summary, the present application has at least one of the following beneficial technical effects:

[0014] 1. The complementary structure design of the above four layers can provide flexible support to the human body while improving the heating and warming performance, without the need to additionally add heating sheets in the protective gear, thereby simplifying the design of the protective gear, reducing the manufacturing cost, and improving the practicality and comfort of the support sheet.

[0015] 2. The hollow microspheres mixed with the adhesive form a light and strong support network, which can disperse pressure and provide stable support, and facilitate the stable connection of the support framework layer between the heat storage surface layer and the heat insulation layer. At the same time, through slight foaming, the adhesive can form a micro-bubble structure inside, making the support framework layer more lightweight and elastic, and improving the comfort of the human body when wearing.

[0016] 3. The heat insulation performance of the porous silicon combined with the micro-bubble structure formed by slight foaming can further slow down the heat transfer efficiency and achieve high-efficiency heat insulation. BRIEF DESCRIPTION OF DRAWINGS

[0023] A flexible heat-generating support sheet of the present application is described below with reference to the accompanying drawings.

[0024] As Figure 1 and Figure 2As shown, the flexible heating support sheet includes a support sheet body 1, which sequentially includes a heat storage surface layer 2, a heating layer 3, a support framework layer 4 and a heat insulation layer 5 from top to bottom, the heat storage surface layer 2 is made of polyethylene fiber, the heating layer 3 includes infrared absorber and ultraviolet light reflector, the support framework layer 4 is made of hollow microsphere layer, and the heat insulation layer 5 is made of porous silicon material, wherein the polyethylene fiber has good heat conduction rate and the structure has a plurality of concave points for heat aggregation, and is used as the heat storage surface layer 2, when being attached to the human body, can quickly absorb the heat of the heating layer 3 and dredge the heat to the human body, and has high mechanical strength, can withstand external force and pressure when being attached to the human body, and ensures the durability of the heat storage effect; by adding infrared absorber and ultraviolet light reflector, the heating layer 3 can continuously absorb the infrared radiation emitted by the human body when being attached to the human body, then after the superposition and oscillation process, new infrared radiation is generated and continuously fed back to the human body, the heating is completed and the relative stable temperature is maintained, at the same time, the far infrared penetrates into the human body, which can promote blood vessel expansion, blood circulation and other health effects of the human body, and the ultraviolet light reflector can effectively reflect the ultraviolet light harmful to the human body, reducing the harm to the human body; the spherical hollow microsphere structure in the hollow microsphere layer is densely arranged, has a plurality of contact points and can be arbitrarily bent, which is used as the support framework layer 4, the plurality of contact points can meet the compression strength of the human body, and the arbitrarily bendable characteristic can provide flexible support force to the human body, improving the comfort of the human body wearing; the porous silicon has high porosity, so that heat is difficult to pass through, which is used as the heat insulation layer 5, can exhibit excellent heat insulation performance, and the porous silicon has the characteristics of lightweight, which can reduce the weight of the product, and is suitable for the use condition of being attached to the human body, the above four layer complementary structure design can provide flexible support to the human body while improving the heating and warming performance, without additionally adding heating sheet in the protector 6, to simplify the design of the protector 6, reduce the manufacturing cost, and improve the practicality and comfort of the support sheet.

[0025] It should be noted that the infrared absorber and the ultraviolet reflector are mainly composed of nano ATO, nano titanium dioxide, nano zirconium oxide, etc. Nano ATO is a kind of nanometer material with excellent conductivity and light transmission. In terms of infrared absorption, it can effectively absorb infrared rays in a specific wavelength range. Nano titanium dioxide is a widely used nanometer material with good ultraviolet reflection and photocatalytic performance. It can effectively reflect ultraviolet rays and reduce the harm of ultraviolet rays to the human body. Nano zirconium oxide is a nanometer material with high hardness and high stability, which has good thermal stability and chemical stability. In combination with nano ATO and nano titanium dioxide, it can assist in playing the functions of infrared absorption and ultraviolet light reflection. The functions of the above components, the heating layer 3 of the present application can absorb the infrared rays emitted by the human body at a specific wavelength, and then sequentially superimpose, oscillate and feedback inside the material. Then, according to the blackbody radiation theory, the infrared rays generated by superposition and oscillation have a wavelength greater than the received infrared rays. Due to the close contact with the human body, the far infrared feedback penetrates, which can maintain a sustained temperature (40°), promote blood circulation in the human body, and accelerate the movement of water molecules in the human body, so as to achieve the promotion of various human health effects. Among them, the composition of the infrared absorber and the ultraviolet reflector is a conventional configuration on the market. The infrared absorber and the ultraviolet reflector can be added between the heat storage surface layer 2 and the support framework layer 4 in a coating manner. The blackbody radiation theory is common knowledge for those skilled in the art, and will not be described here.

[0026] Further, the hollow microsphere layer is made of slightly foamed hollow microspheres and adhesive. The hollow microspheres and the adhesive form a light and strong support network that can disperse pressure and provide stable support. It is convenient for the support framework layer 4 to be stably connected between the heat storage surface layer 2 and the thermal insulation layer 5. At the same time, through slight foaming, the adhesive can form a micro-bubble structure inside, so that the support framework layer 4 is more lightweight and elastic, which can improve the comfort of the human body wearing.

[0027] Further, the thermal insulation layer 5 forms a multi-network structure by slightly foaming the porous silicon material. The heat insulation performance of the porous silicon in combination with the micro-bubble structure formed by slight foaming can further slow down the heat transfer efficiency and achieve high-efficiency thermal insulation.

[0028] In addition, in the embodiment, the polyethylene fiber used in the heat storage surface layer 2 has a thickness of 0.1-0.5 mm, the heating layer 3 has a thickness of 0.01-0.05 mm, the hollow microsphere layer used in the support framework layer 4 has a thickness of 0.5-2 mm, the porous silicon material used in the heat insulation layer 5 has a thickness of 0.5-0.8 mm, and the total thickness of the heat storage surface layer 2, the heating layer 3, the support framework layer 4 and the heat insulation layer 5 is not more than 3 mm.

[0029] It should be noted that the flexible heating support sheet of the present application can be applied to various health protection devices 6 for the human body, such as neck protection, shoulder protection, elbow protection, wrist protection, waist protection, uterus warming, knee protection, ankle protection, etc. The flexible heating support sheet can be arranged in the protection device 6 for contacting the human body, or can be directly attached to the part of the human body that needs support, such as the waist, the shoulder, the elbow, the wrist, etc.

[0030] The above detailed description does not constitute a limitation on the protection scope of the present application. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors.
