Technical Field
[0001] This utility model relates to the field of graphene heating element technology, and in particular to a wearable graphene heating element. Background Technology
[0002] Graphene heating pads are flexible thin-film heating elements made using the electrothermal conversion properties of graphene materials. They efficiently convert electrical energy into heat energy by passing electricity through them. When worn, graphene heating clothing made from graphene heating pads can quickly warm the body and promote blood circulation, metabolism, regulate bodily functions, and enhance the body's immunity.
[0003] Patent CN212416692U discloses a graphene-heated top, including sleeves, a front panel, and a back panel. An upper graphene heating element is located on the shoulders and back of the back panel, and a lower graphene heating element is located on the waist and back of the back panel. Wires are mounted on both the upper and lower graphene heating elements. This patent proposes using graphene sheets to provide far-infrared therapy to the shoulders, neck, waist, and back, enabling health maintenance during active work and daily life. However, this patent still has some problems in its use. Because the graphene heating elements in the patent are covered by cotton layers on both sides, with the outer layer of the cotton layer being the fabric layer of the garment, the graphene heating elements are prone to mechanical damage during wear, affecting their heating effect.
[0004] Therefore, it is necessary to design a wearable graphene heating element with a protective structure. Utility Model Content
[0005] In order to overcome the shortcomings of the above-mentioned patent, where the graphene heating element is covered by a cotton layer on both the top and bottom sides, and the outer side of the cotton layer is the fabric layer of the clothing, which makes the graphene heating element prone to mechanical damage during wear and affects the heating effect of the graphene heating element, the technical problem of this utility model is to provide a wearable graphene heating element with a protective structure.
[0006] A wearable graphene heating element includes a vest and a zipper. The vest has a zipper on the front and includes a PET composite protective layer, a polyimide film, a graphene heating element, a first hook and loop fastener, a first hook and loop fleece, a second hook and loop fastener, a second hook and loop fleece, and a power module. The first hook and loop fleece is installed on the back of the vest's interior, and two second hook and loop fleece are installed on the front of the vest's interior. The graphene heating element is attached to the inside of the PET composite protective layer, and a polyimide film is attached to the inside of the graphene heating element. The first hook and loop fastener is installed on the back of the PET composite protective layer and is attached to the first hook and loop fleece. The second hook and loop fastener is installed on both sides of the front of the PET composite protective layer and is attached to the second hook and loop fleece. The power module is installed on the back of the vest, and a control switch is installed on the power module. The graphene heating element is electrically connected to the power module.
[0007] Further explanation: It also includes a miniature fan, elastic fixing straps, and a flow guide tube. Multiple elastic fixing straps are installed on the lower part of the vest, and a flow guide tube is installed between the multiple elastic fixing straps. Multiple flow guide holes are opened on the flow guide tube, and a miniature fan is installed on the rear side of the flow guide tube. The miniature fan is electrically connected to the power module.
[0008] To further explain, the vest has a first heat dissipation hole at the bottom, a second heat dissipation hole on the PET composite protective layer, and a third heat dissipation hole on the polyimide film.
[0009] To further explain, it also includes protective strips; multiple protective strips are installed on one side of the front of the vest, covering the zipper.
[0010] To further explain, the flow guide hole is positioned facing the center of the vest.
[0011] To further explain, it also includes a protective net; a protective net is installed on the side of the miniature fan away from the guide tube.
[0012] Compared with the prior art, the present invention has the following advantages: 1. After the user wears the vest, the switch is turned on to turn on the graphene sheet to generate heat. The polyimide film transfers the heat to prevent the user from overheating in a localized area. The PET composite protective layer covers the outside of the graphene heating sheet to protect the heating sheet from external wear, liquid infiltration and other damage.
[0013] 2. By turning on the miniature fan, air flows into the guide tube, then is blown out evenly through the guide hole, and then discharged through the third heat dissipation hole, the second heat dissipation hole, and the first heat dissipation hole in sequence. This helps to remove the heat and water vapor from the patient when wearing the vest, keeping the patient comfortable. Attached Figure Description

Detailed Implementation
[0020] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.
[0021] Example 1: A wearable graphene heating element, see 1- Figure 4As shown, the vest includes a vest 1, a PET composite protective layer, and a zipper 2. The zipper 2 is sewn onto the front of the vest 1. Four protective strips 16 are sewn onto the right front of the vest 1, covering the zipper to prevent the metal parts of the zipper from directly contacting the skin and causing discomfort or allergies, and also improving aesthetics. The vest also includes a PET composite protective layer 3, a polyimide film 4, a graphene heating element 5, a first hook and loop fastener 6, a first hook and loop fastener 601, a second hook and loop fastener 7, a second hook and loop fastener 701, and a power module 8. The first hook and loop fastener 601 is sewn onto the back inside of the vest 1. The front inside of the vest 1... Two second hook and loop fasteners 701 are installed by sewing. A graphene heating element 5 is attached to the inside of the PET composite protective layer 3. A polyimide film 4 is attached to the inside of the graphene heating element 5. A first hook and loop fastener 6 is installed on the back of the PET composite protective layer 3. The first hook and loop fastener 6 is attached to the first hook and loop fastener 601. Second hook and loop fasteners 7 are installed on both sides of the front of the PET composite protective layer 3 by sewing. The second hook and loop fasteners 7 are attached to the second hook and loop fasteners 701. A power module 8 is installed on the back of the vest 1 by sewing. A control switch 801 is installed on the power module 8. The graphene heating element 5 is electrically connected to the power module 8.
[0022] When wearing this device, the user puts on vest 1, then tightens zipper 2, and activates graphene heating element 5 via control switch 801. After power module 8 supplies power, current flows through graphene heating element 5, utilizing the resistive effect of graphene to convert electrical energy into heat energy. The heating element heats the body evenly through polyimide film 4, avoiding localized overheating. When vest 1 needs to be cleaned, the first hook and loop fastener 6 is separated from the first hook and loop fastener 601, and the second hook and loop fastener 7 is separated from the second hook and loop fastener 701, thus removing the polyimide film 4 and P... The PET composite protective layer and graphene heating element 5 can be removed from the vest 1, allowing the vest 1 to be washed separately. The PET composite protective layer covers the outside of the graphene heating element 5, protecting it from external wear and liquid infiltration, while also reflecting and transferring heat towards the human body. When wearing this device, the user can adjust the position of the graphene heating element 5 up and down, and then attach the first hook and loop fastener 6 to the first hook and loop fastener 601, and the second hook and loop fastener 7 to the second hook and loop fastener 701, thereby improving the applicability of this device.
[0023] Example 2: Based on Example 1, refer to 1 and Figure 5As shown, it also includes a miniature fan 9, elastic fixing straps 10, and a guide tube 11. Four elastic fixing straps 10 are installed on the lower part of the vest 1, and a guide tube 11 is installed between the multiple elastic fixing straps 10. Multiple guide holes 12 are opened on the guide tube 11, and the guide holes 12 are set towards the center of the vest 1. The miniature fan 9 is installed on the rear side of the guide tube 11 by bolts. The miniature fan 9 is electrically connected to the power module 8. The lower part of the vest 1 has a first heat dissipation hole 13 along the circumference. The PET composite protective layer 3 has a second heat dissipation hole 14 along the circumference. The polyimide film 4 has a third heat dissipation hole 15. A protective net 17 is installed on the rear side of the miniature fan 9 away from the guide tube 11 by bolts. The protective net 17 prevents clothing, hair, or foreign objects from being sucked into the blades of the miniature fan 9.
[0024] When the user feels overheated, the miniature fan 9 is turned on. The miniature fan 9 draws in outside air through the guide tube 11. After the air flows into the guide tube 11, it is blown out evenly through multiple guide holes 12 set on the tube wall facing the center of the vest 1. The airflow direction is towards the center of the vest 1. The airflow is then discharged through the third heat dissipation hole 15, the second heat dissipation hole 14 and the first heat dissipation hole 13 in sequence. This helps to remove the heat and water vapor from the patient when wearing the vest 1, so that the patient can stay comfortable when wearing the vest 1.
