AI Technical Summary
Existing water-heated blankets use ordinary PVC hoses, which have high thermal resistance, resulting in low heat conversion efficiency and an inability to effectively transfer heat from the water pipes to the human body.
Graphene tubes are used to replace ordinary PVC hoses. The graphene tubes are made by melt injection molding with 15% graphene powder added to a polyvinyl chloride PVC base to form a serpentine heat-conducting component. Combined with the hollow structure inside the blanket and the design of heat insulation cotton, the heat is evenly distributed and retained.
It improves heat transfer efficiency, provides stable and uniform heating, ensures user safety and energy saving, and has excellent thermal conductivity and durability.

Abstract
Description
Technical Field
[0001] This utility model relates to water-heated blankets, specifically a graphene heat-conducting hose water-heated blanket. Background Technology
[0002] The heating principle of water-heated blankets is that the main unit's water tank heats the water and transmits the heat to the flexible tubes arranged inside the blanket. Currently, most water-heated blankets on the market use ordinary PVC material as the tube material. However, ordinary PVC tubes have a large thermal resistance and cannot efficiently convert the heat of the water in the water pipes of the water-heated blanket into the heat that comes into contact with the person. Utility Model Content
[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a graphene thermal conductive hose water-heated blanket, which effectively solves the problem that the current water-heated blanket market mostly uses ordinary PVC material as the hose material. Ordinary PVC hoses have high thermal resistance and cannot efficiently convert the heat of the water in the water pipe of the water-heated blanket into heat when in contact with people.
[0004] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a blanket body, a heat-conducting component, and a graphene tube. The interior of the blanket body is a hollow structure, and a heat-conducting component is installed inside the blanket body. The heat-conducting component is composed of parallel tubes and arc-shaped tubes spliced together, and the parallel tubes and arc-shaped tubes are spliced together in a serpentine shape.
[0005] The heat-conducting component is made of graphene tubes.
[0006] Preferably, the graphene tube is made by melt injection molding of a polyvinyl chloride (PVC) substrate with added graphene powder.
[0007] Preferably, one end of the heat-conducting component is connected to the outlet of the external water heating unit, and the other end of the heat-conducting component is connected to the return port of the external water heating unit.
[0008] Preferably, the thickness of the graphene tube is between 0.5 mm and 1.5 mm.
[0009] Preferably, the lower and side surfaces of the blanket are provided with heat insulation cotton.
[0010] Beneficial effects: 1. Highly efficient and stable heating: Utilizing the excellent thermal conductivity of graphene composite materials, the preset temperature is quickly reached, avoiding the problems of local overheating or cooling that may occur in some traditional heating methods, providing users with a warm and comfortable sleeping environment;
[0011] 2. Safe and durable: Graphene composite materials have excellent durability and stability.

[0018] The following is in conjunction with the appendix Figure 1-3 The specific embodiments of this utility model will be described in further detail.
[0019] Example 1, by Figure 1-3 The present invention provides a graphene thermally conductive hose water-heated blanket, including a blanket body 1, a thermally conductive component 2 and a graphene tube 3. The interior of the blanket body 1 is a hollow structure, and the thermally conductive component 2 is installed inside the blanket body 1. The thermally conductive component 2 is composed of parallel tubes and arc-shaped tubes spliced together, and the parallel tubes and arc-shaped tubes are spliced together in a serpentine shape.
[0020] Blanket 1: The interior of Blanket 1 is hollow, and its lower and side surfaces are lined with heat insulation cotton. This not only effectively prevents heat loss and improves energy efficiency, but also avoids the risk of burns caused by contact with overheated surfaces, ensuring safe use.
[0021] Heat-conducting component 2: Heat-conducting component 2 is installed inside the blanket body 1 and is composed of parallel tubes and arc-shaped tubes spliced together in a serpentine shape. This unique shape design greatly increases the heat-conducting area, allowing heat to be distributed more evenly on the blanket body, providing users with all-around warm coverage.
[0022] The heat-conducting component 2 is made of graphene tube 3, which is made by melt injection molding of 15% graphene powder added to a polyvinyl chloride (PVC) base. This material combination fully utilizes the excellent thermal conductivity of graphene, while taking advantage of the stability and plasticity of PVC to ensure the durability and reliability of the graphene tube 3.
[0023] Connection method: One end of the heat-conducting component 2 is connected to the outlet of the external water heating unit, and the other end is connected to the return port of the external water heating unit, forming a complete water heating circulation system. Through the operation of the water heating unit, hot water circulates in the heat-conducting component 2 to achieve heat transfer.
[0024] Working Principle: When this utility model is in use, hot water flows from the outlet into the heat-conducting component 2 and along the serpentine graphene tube 3. The graphene tube 3, with its excellent thermal conductivity, quickly transfers the heat from the hot water to the entire blanket 1. Since the thickness of the graphene tube 3 is between 0.5mm and 1.5mm, it ensures sufficient thermal conductivity without making the blanket too thick and affecting comfort. Simultaneously, the insulation cotton on the lower and side surfaces of the blanket 1 effectively prevents heat loss downwards and to the sides, concentrating heat primarily on the upper surface of the blanket, providing users with a longer-lasting and more concentrated warmth. After flowing through the heat-conducting component 2, the hot water flows back to the water-conducting unit from the return outlet, completing one cycle. This cycle repeats continuously, providing heating to the user.
[0025] Beneficial effects: This utility model has a novel structure and utilizes the superior physical properties of graphene to composite flexible tubing material, thereby improving the heat conduction efficiency of water-heated blankets.
[0026] By utilizing the infrared emission properties of graphene material and combining it with the heat transfer function of the water-heated blanket's heat-conducting hose, heat can be transferred to the human body more effectively, achieving a certain degree of therapeutic effect.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
