Description

Technical Field

[0001] The utility model discloses a double-heating blanket-shaped heating element, which belongs to the technical field of heating. Background Art

[0002] With technological advancements, heating methods have become more diverse. Existing Chinese patent CN105902079B discloses a smart electric blanket that includes a heating wire unit, which includes left and right heating wires, each coiled in two separate rows. Both the left and right heating wires are connected to a control panel. This electric blanket generates heat through resistance, which heats quickly and reaches high temperatures, but consumes a significant amount of power during the heating process.

[0003] Existing Chinese patent CN212921236U discloses a graphene heating foot and seat cushion device for automobiles, comprising a heating pad and a temperature control device. The heating pad includes a graphene heating film layer, which is electrically connected to a temperature control switch via a power cord. A power transformer and a power conversion plug are also electrically connected to the power cord. The power conversion plug is connected to the automobile and, in turn, to the automobile's cigarette lighter. The device uses the 12V voltage from the automobile's cigarette lighter port as power and utilizes the graphene heating film layer to achieve heating. However, in the presence of low current, relying solely on the graphene heating film layer to generate heat cannot meet heating needs. Utility Model Content

[0004] In order to solve the problems of excessive power consumption in the heating process and the inability to meet the heating needs under low voltage, the utility model proposes a double heating blanket-shaped heating element.

[0005] In order to solve the above technical problems, the technical solutions of the present utility model 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 electronic control component; the heat-transmitting layer 1 is placed on the top layer, the heating layer 2 is fixedly adhered above the heat-transmitting layer 1, and the heating layer 2 is electrically connected to the electronic control component, the heat-insulating layer 3 is fixedly adhered above the heating layer 2, and the anti-slip layer 4 is fixedly adhered above the heat-insulating layer 3;

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

[0008] Graphene carbon nano heating material is evenly sprayed on the base film; unevenly sized and continuous honeycomb-shaped metal conductive wires 2-1 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 reflective film is pressed on the metal conductive wires 2-1, wherein the mirror reflective film on the pressing layer tightly combines the graphene carbon nano heating material and the metal conductive wires 2-1;

[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 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 combination of graphene carbon nano heating material and 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. 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; when the graphene carbon nano heating material is combined with the metal conductive wires for heating, only a low voltage of 5V is required to be input to enable the blanket-like heating element to quickly heat up and heat, meeting the need for weak current input to enable the heating layer to generate heat, and because the internal honeycomb-shaped metal conductive wires will form a wave-like heating effect, compared with the existing technology, the heating capacity is stronger, the heating effect is clearer, and it can meet the need for rapid heating at low voltage.

[0012] A heat-permeable layer with several circular holes is provided above the heating layer. The heat generated by the heating layer will be radiated upward through the heat-permeable layer. 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 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 element.

[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 the long-term radiation heating process, 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 This is a schematic structural diagram of the double-heating blanket-like heating element of the present invention, and is also used as an abstract drawing.

[0016] Figure 2 This 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 made of PU leather or PV leather, with a number of circular holes evenly distributed on its surface. The circular holes can transmit the heat generated by the heating layer 2 outward in the form of radiation, which facilitates the heat to pass through the heat-transmitting layer 1, thereby achieving the heating effect.

[0019] The metal conductive wire 2-1 is a copper wire, and the heating layer 2 is provided with unevenly 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 demand for rapid heating.

[0020] The temperature control switch 6 is equipped 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 or 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, you can buy a commercially available USB interface conversion head to make the blanket-like heating element meet the usage requirements of different interfaces in different usage scenarios, making it more widely used, 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 the heat radiated by the heating layer 2 more durable.

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

[0024] The above embodiments are merely examples for clarity of explanation and are not intended to limit the embodiments. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
