Description

Technical Field

[0001] The double-heating blanket-shaped heating element of the present invention belongs to the technical field of heating. Background Art

[0002] With the advancement of technology, the ways of heating and keeping warm have become more diverse. The existing Chinese patent CN105902079B discloses an intelligent electric blanket, which includes a heating wire unit, and the heating wire unit includes a left heating wire and a right heating wire, and the left heating wire and the right heating wire are respectively arranged to be coiled into two independent rows, and the left heating wire and the right heating wire are both connected to the control panel. The electric blanket generates heat through resistance, and although it heats up quickly and has a high temperature, it consumes too much electricity during the heating process.

[0003] The existing Chinese patent CN212921236U discloses a graphene heating foot pad and seat cushion device for automobiles, including a heating pad and a temperature control device. The heating pad includes a graphene heating film layer, the graphene heating layer is electrically connected to the temperature control switch through a power line, the power transformer and the power conversion plug are electrically connected to the power line, and the power conversion plug is connected to the automobile and is connected to the cigarette lighter of the automobile. It uses the 12V voltage of the cigarette lighter port on the automobile as power supply and uses the graphene heating film layer to achieve heating. However, in the case of low current, relying solely on the graphene heating film layer to generate heat cannot meet the heating needs. Summary of the invention

[0004] In order to solve the problems of excessive power consumption during heating and failure to meet heating needs under low voltage, the present invention proposes a double heating blanket-like heating element.

[0005] In order to solve the above technical problems, the technical solutions of the present invention are as follows:

[0006] Double heating blanket heating element, such as Figure 1 and Figure 2 As shown, it includes a heat-transmitting layer 1, a heating layer 2, a heat-insulating layer 3, an anti-slip layer 4 and an electric control component; the heat-transmitting layer 1 is placed on the uppermost layer, the heating layer 2 is fixedly adhered on the heat-transmitting layer 1, and the heating layer 2 is electrically connected to the electric control component, the heat-insulating layer 3 is fixedly adhered on the heating layer 2, and the anti-slip layer 4 is fixedly adhered on the heat-insulating layer 3;

[0007] The heating layer 2 includes a base film cloth, graphene carbon nano heating material, a metal conductive wire 2-1 and a mirror reflection film;

[0008] The graphene carbon nano heating material is evenly sprayed on the base film cloth; the metal conductive wires 2-1 with uneven sizes and continuous honeycomb shape are laid on the graphene carbon nano heating material, and the graphene carbon nano heating material is evenly coated on the metal conductive wires 2-1; a layer of mirror reflection film is pressed on the metal conductive wires 2-1, wherein the mirror reflection film on the pressing makes the graphene carbon nano heating material and the metal conductive wires 2-1 tightly combined;

[0009] The electric control assembly includes a power cord 5, a temperature control switch 6 and a power connection plug 7;

[0010] Among them, one end of the power cord 5 is electrically connected to the metal conductive wire 2-1 in the heating layer 2, and the other end of the power cord 5 is electrically connected to the power connection plug 7. A temperature control switch 6 is provided on one end of the power cord 5 and close to the power connection plug 7.

[0011] The beneficial effects of the present invention are as follows: the present invention provides a double-heating blanket-like heating element, the heating layer adopts a method of combining graphene carbon nano heating material with uneven-sized and continuous honeycomb-shaped metal conductive wires. When voltage is input, a large number of free electrons in the graphene carbon nano heating material will produce irregular motion under the excitation of electric energy, collide and rub against each other, thereby generating heat energy; the irregular-shaped metal conductive wires will also generate heat energy due to resistance, and the combination of the graphene carbon nano heating material and the metal conductive wires enables the blanket-like heating element to perform double heating, thereby enhancing the heating capacity of the heating layer and meeting the needs of heating and heating; in the process of heating by combining the graphene carbon nano heating material with the metal conductive wires, only a lower voltage of 5V needs to be input to enable the blanket-like heating element to quickly heat up and heat, meeting the need for the heating layer to generate heat with weak current input, and because the internal honeycomb-shaped metal conductive wires will form a wave-like heating effect, compared with the prior art, the heating capacity is stronger, the heating effect is clearer, and the need for rapid heating at low voltage can be met.

[0012] A heat-permeable layer with several circular holes is provided on top of the heating layer. The heat generated by the heating layer will be radiated upward through the heat-permeable layer and transferred. During this process, the cold air in the upper layer will sink downward through the breathable layer and come into contact with the heating layer. The generated heat and the sinking cold air form a vortex in the heating layer, thereby increasing the speed at which the heat is radiated upward in a wave-like manner. On the other hand, the heat-permeable layer is both flexible and flame-retardant, which improves the safety of the blanket-like heating body.

[0013] A thermal insulation layer is pasted under the heating layer. The material of the thermal insulation layer is aerogel felt. The aerogel felt has a high density and a very low thermal conductivity. During long-term radiation heating, the temperature will not penetrate the thermal insulation layer and reduce the inward erosion of cold air. Therefore, the purpose of thermal insulation can be achieved, greatly reducing the loss of heat generated by the heating layer.

[0014] The USB interface of the power connection plug of the blanket-like heating element reduces the power consumption during the heating process. According to different usage requirements, it can be equipped with a USB interface conversion head to meet the usage requirements of different plug interfaces in different usage scenarios, making the application more extensive, convenient and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 The schematic diagram of the structure of the double-heating blanket-like heating element of the present invention is also used as the abstract drawing.

[0016] Figure 2 It is a schematic diagram of the metal conductive wires in the heating layer of the double heating blanket-like heating element of the present invention. DETAILED DESCRIPTION

[0017] The present invention needs to be further defined as follows.

[0018] like Figure 1 and Figure 2 As shown, the heat-transmitting layer 1 is PU leather or PV leather, wherein a plurality of circular holes are evenly distributed on the surface of the heat-transmitting layer 1. The circular holes can transmit the heat generated by the heating layer 2 to the outside in the form of radiation, which is more conducive to the heat passing through the heat-transmitting layer 1, thereby achieving the effect of heating.

[0019] The metal conductive wire 2-1 is a copper wire, and the heating layer 2 is provided with uneven-sized and continuous honeycomb-shaped copper wires. The length of the copper wire used is longer, which increases the resistance value of the heating layer and makes the resistance of the copper wire larger. After power is turned on for heating, the temperature rises faster. As the temperature rises, the resistivity of the copper wire will also increase, causing the resistance to increase accordingly. This satisfies the requirement that the heating layer 2 can be heated at a low voltage while also meeting the requirement of rapid heating.

[0020] The temperature control switch 6 is provided with a step-down chip, which adjusts the input voltage. By adjusting the input voltage through the temperature control switch 6, the resistance of the metal conductive wire 2-1 is changed, and the heating layer 2 can be adjusted to high and low to meet different heat requirements.

[0021] The power connection plug 7 is a USB interface. Since the interfaces provided in different usage scenarios are not all USB interfaces, a commercially available USB interface conversion head can be purchased to make the blanket-shaped heating element meet the usage requirements of different interfaces in different usage scenarios, making the application more extensive, convenient and easy to operate.

[0022] The heat-insulating layer 3 is aerogel felt, which has both flexibility and heat-insulating properties, making the structure of the blanket-like heating element more stable and maintaining the heat radiated by the heating layer 2 longer-lasting.

[0023] The anti-skid layer 4 is a rubber anti-skid pad. The rubber anti-skid pad at the bottom will generate friction during the use of the blanket-like heating element to prevent it from moving at will and affecting safety.

[0024] The above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present invention.
