Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric heating appliances, specifically to a uniform temperature electric blanket with a mesh heat-conducting structure. Background Technology
[0002] Currently, traditional electric blankets are widely used in people's daily lives to provide warmth in cold environments.
[0003] However, traditional electric blankets often use ordinary heating wires or heating films for heat conduction, lacking efficient heat conduction structures. This results in uneven heat distribution and a tendency for localized overheating, affecting comfort and posing a risk of burns. In terms of safety, ordinary insulation materials and protective designs are insufficient to withstand high temperatures and electrical leakage. The power cord also lacks effective protection, making it prone to damage and short circuits. Furthermore, traditional electric blankets have poor insulation, allowing heat to dissipate downwards, wasting energy and potentially causing fires due to heat buildup.
[0004] Therefore, there is an urgent need for a new type of electric blanket that can effectively solve the problem of uniform heat conduction, while improving safety in many aspects such as insulation, flame retardancy, and power cord protection. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform temperature electric blanket with a mesh-like heat-conducting structure.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a uniform temperature electric blanket with a mesh heat-conducting structure, comprising a main body, an uppermost surface layer, an insulating layer below the surface layer, the surface layer being stitched to the insulating layer, a mesh heat-conducting layer below the insulating layer, and a high-temperature resistant epoxy resin adhesive coated on the lower surface of the insulating layer, which is then heated and cured to connect the insulating layer and the mesh heat-conducting layer together. A heating layer is connected to the lower surface of the mesh heat-conducting layer by ultrasonic welding. A precision-etched serpentine circuit is provided on the surface of the heating layer for current passage. A heat insulation layer is provided below the heating layer, and the heating layer and the heat insulation layer are bonded together with silicone rubber. The heat insulation layer is stitched to the base layer.
[0007] As a further description of the above technical solution:
[0008] The surface layer uses either a soft and comfortable cotton or wool fabric to provide a tactile and comfortable feel.
[0009] As a further description of the above technical solution:
[0010] The insulating layer is made of high-temperature resistant polytetrafluoroethylene film and covers the upper surface of the mesh thermally conductive layer for insulation.
[0011] As a further description of the above technical solution:
[0012] The mesh heat-conducting layer uses a fine mesh structure made of metallic copper to uniformly transfer heat.
[0013] As a further description of the above technical solution:
[0014] The heating layer uses a graphene nanofiber heating film for generating heat and providing heat.
[0015] As a further description of the above technical solution:
[0016] The insulation layer is made of aerogel felt and is used for heat insulation to prevent heat loss downwards.
[0017] As a further description of the above technical solution:
[0018] The base layer includes an aramid fiberboard for insulation and flame retardancy. The main body is also surrounded by a wear-resistant edge strip made of a blend of polyester and aramid fibers to prevent fabric damage at the edges and exposure of the internal structure. A protective sleeve is also provided on one side of the wear-resistant edge strip. The protective sleeve is made of flame-retardant thermoplastic polyurethane elastomer to wrap the power cord and prevent damage to the power cord.
[0019] This utility model has the following beneficial effects:
[0020] First, through the fine mesh heat-conducting layer made of metallic copper, the heat generated by the graphene nano heating film can be quickly and evenly diffused to the entire surface of the electric blanket, overcoming the problems of local overheating and uneven temperature in traditional electric blankets, and providing users with a more comfortable and stable heating experience.
[0021] Second, the high-temperature resistant film insulation layer, aramid fiberboard base layer, and flame-retardant protective sleeve reduce electrical risks from multiple dimensions such as insulation, flame retardancy, and power line protection.

[0031] Example 1:
[0032] like Figures 1 to 4As shown in the figure, this embodiment provides a uniform temperature electric blanket with a mesh heat-conducting structure, including a main body 1. The uppermost layer of the main body 1 is provided with a surface layer 2. An insulating layer 3 is provided below the surface layer 2, and the surface layer 2 is connected to the insulating layer 3 by stitching. A mesh heat-conducting layer 4 is connected below the insulating layer 3, and the lower surface of the insulating layer 3 is coated with high-temperature resistant epoxy resin. After heating and curing, the insulating layer 3 and the mesh heat-conducting layer 4 are connected together. A heating layer 5 is connected to the lower surface of the mesh heat-conducting layer 4 by ultrasonic welding. A precision etched serpentine circuit is provided on the surface of the heating layer 5 for current to pass through. A heat insulation layer 6 is provided below the heating layer 5, and the heating layer 5 and the heat insulation layer 6 are bonded together by silicone rubber. The heat insulation layer 6 is connected to the base layer 7 by stitching.
[0033] In this embodiment, the insulating layer 3, the mesh heat-conducting layer 4, the heating layer 5, and the heat insulation layer 6 constitute a uniform temperature electric blanket with a mesh heat-conducting structure according to this application.
[0034] Specifically, the surface layer 2 uses either a soft and comfortable cotton or wool fabric to provide a tactile feel and comfort.
[0035] In this embodiment, the surface layer 2 provides the user with a good tactile feel and comfort, while allowing heat to be evenly transferred to the human body. The high-temperature resistant sewing thread of the surface layer 2 is sewn to the insulation layer 3 using a straight stitch or overlock stitch to ensure the strength and aesthetics of the stitch, while also paying attention to the tightness and uniformity of the stitch to prevent heat loss from the seam.
[0036] Specifically, the insulating layer 3 is made of high-temperature resistant polytetrafluoroethylene film and covers the upper surface of the mesh thermally conductive layer 4 for insulation.
[0037] As a preferred embodiment, the insulating layer 3 is made of high-temperature resistant polytetrafluoroethylene film and covers the surface of the heating wire layer. It serves to insulate and prevent the heating wire from directly contacting the human body, ensuring safe use. The insulating layer 3 and the mesh heat-conducting layer 4 are bonded together with high-temperature resistant epoxy resin adhesive. The epoxy resin adhesive has good adhesion and insulation properties and can maintain a stable bonding effect in high-temperature environments.
[0038] Example 2:
[0039] A mesh heat-conducting layer 4 is provided based on Example 1.
[0040] Specifically, the mesh heat-conducting layer 4 uses a fine mesh structure made of metallic copper to uniformly transfer heat.
[0041] In this embodiment, the mesh heat-conducting layer 4 uses a fine mesh structure made of metallic copper. Metallic copper has excellent thermal conductivity, which can quickly conduct heat to the entire surface of the electric blanket to achieve a uniform temperature effect. The mesh structure design can increase the contact area with the upper and lower layers and improve the heat transfer efficiency. The mesh heat-conducting layer 4 and the heating layer 5 are firmly connected at the edges of the mesh heat-conducting layer 4 and the heating layer 5 through ultrasonic welding technology, ensuring that heat can be quickly transferred from the heating layer to the mesh heat-conducting layer, and the connection will not loosen due to long-term use.
[0042] Specifically, the heating layer 5 is a graphene nanoheating film used for generating heat and providing heat.
[0043] With this configuration, heating layer 5 uses a graphene nano heating film, which has the characteristics of high heating efficiency, low resistivity and good flexibility. It can heat up quickly and evenly. At the same time, graphene material also has good chemical stability and oxidation resistance, and has a long service life. The surface of the heating film is provided with a precision-etched serpentine circuit to ensure that the current passes through evenly and further improve the heating uniformity. Heating layer 5 is located in the middle core layer of the entire electric blanket structure.
[0044] Example 3:
[0045] A heat insulation layer 6 is provided based on Example 2.
[0046] Specifically, the heat insulation layer 6 is made of aerogel felt and is used for heat insulation to prevent heat loss downwards.
[0047] The insulation layer is made of aerogel felt, which has excellent heat insulation performance. It can effectively prevent heat loss to the bottom layer, improve the thermal efficiency of the electric blanket, and also play a certain role in sound insulation, providing users with a quieter and more comfortable environment. The heating layer 5 and the insulation layer 6 are bonded together using high-temperature resistant silicone rubber. Silicone rubber has good elasticity and high-temperature resistance, which can ensure the bonding strength while adapting to temperature changes during the use of the electric blanket, preventing cracking at the bonding joint due to thermal expansion and contraction.
[0048] Specifically, the base layer 7 includes an aramid fiberboard for insulation and flame retardancy. The main body 1 is also provided with wear-resistant edge strips 8 around its perimeter. The wear-resistant edge strips 8 are made of a blend of polyester fiber and aramid fiber to prevent fabric damage at the edges and exposure of the internal structure. A protective sleeve 9 is also provided on one side of the wear-resistant edge strip 8. The protective sleeve 9 is made of flame-retardant thermoplastic polyurethane elastomer to wrap the power cord and prevent damage to the power cord.
[0049] In this embodiment, the base layer 7 is made of aramid fiberboard. Aramid fiberboard has excellent properties such as high strength, high temperature resistance, and flame retardancy, which can provide good safety and stability for electric blankets, and can also play a certain role in insulation.
[0050] The wear-resistant edge banding strip 8 is made of a blend of polyester and aramid fibers. The polyester fibers ensure that the edge banding strip has good wear resistance and flexibility, while the aramid fibers give it high strength and high temperature resistance. It can effectively resist friction and pulling in daily use, prevent the fabric at the edge from being damaged and the internal structure from being exposed. The edge banding strip is sewn to the fabric layer through a double-line overlocking process. The sewing thread is also made of high-temperature resistant and high-strength polyester thread to ensure that the edge banding strip is tightly bonded to the main body of the electric blanket and is not easy to come apart.
[0051] A dedicated protective sleeve 9 is installed at the power interface. The protective sleeve 9 is made of flame-retardant thermoplastic polyurethane elastomer material, which has high elasticity, high strength and good weather resistance.
[0052] In actual use, when the main body 1 is powered on, the current flows through the serpentine circuit precisely etched on the surface of the graphene nano-heating film of the heating layer 5. Under the action of the electric field, electrons in the unique two-dimensional honeycomb crystal structure of graphene gain energy and move in a directional manner. During the movement, they collide with the crystal lattice, converting electrical energy into heat energy, causing the heating layer 5 to heat up rapidly. Subsequently, the heat generated by the heating layer 5 is quickly transferred to the upper mesh heat-conducting layer 4. The mesh heat-conducting layer 4 is a fine mesh structure made of metallic copper. With its high thermal conductivity and large specific surface area, it can quickly capture heat and conduct the heat evenly to the surface layer 2 along the shortest path, achieving a uniform temperature effect. Meanwhile, the surface layer 2 uses soft and comfortable cotton or wool fabric, directly contacting the user and providing a good tactile feel and comfort. The insulation layer 3 is made of high-temperature resistant polytetrafluoroethylene film, covering the upper surface of the mesh heat-conducting layer 4, and is connected to the mesh heat-conducting layer 4 by high-temperature resistant epoxy resin. The excellent electrical insulation performance of the insulation layer 3 can effectively isolate current and prevent electric shock to the user. At this time, the heat insulation layer 6 uses aerogel felt, whose extremely low thermal conductivity can effectively prevent heat loss downwards and improve heat utilization. The aramid fiber board of the wear-resistant edge strip 8 provides insulation and flame-retardant protection, enhancing the safety and stability of the electric blanket. The wear-resistant edge strip 8 around the main body 1 is made of polyester fiber and aramid fiber blend material, connected to the main body 1 by double-line locking process to resist daily friction and pulling. The protective sleeve 9 at the edge interface is made of flame-retardant thermoplastic polyurethane elastomer material, which wraps the power cord inside to prevent the power cord from being damaged by pulling and bending, ensuring the long-term stable operation of the electric blanket.
