Problems solved by technology

Ordinary chair cushions are only filled with cotton wool in the cushion cover to keep warm. When the weather is cold, ordinary chair cushions cannot meet people's needs. Chair cushions with heating function can meet people's needs in winter.
[0003] However, the existing chair cushions with heating function require a higher power supply voltage. On the one hand, once the high voltage leaks, it will cause an electric shock, and the safety performance is not good. demanding

preparation example Construction

[0106] The preparation method of the above-mentioned heating film 210 is relatively simple, saving time and material cost. At the same time, the electrode layer is prepared by using metal foil, which has good conductivity and is beneficial to control the uniformity of the temperature of the heating film.

[0107] Preferably, the thickness of the first adhesive layer 213 and the second adhesive layer 217 is 25-75 μm.

[0108] see Figure 5 , the structure of another embodiment of the chair pad is substantially the same as that of the chair pad 10, the difference is that in the illustrated embodiment, the heating film 410 of the chair pad includes a first insulating layer 412, a conductive layer 414, and an electrode stacked in sequence. layer 416 , a second adhesive layer 417 and a second insulating layer 418 . The second insulating layer 418 is bonded to the electrode layer 416 through the second insulating layer 418 . Preferably, the material of the second adhesive layer 41...

Embodiment 1

[0125] Please also see image 3 and Figure 4 , single-layer graphene is used as the conductive layer of the heating film, and the electrode layer is printed with silver paste.

[0126] 1. Transfer a layer of graphene on the PET (first insulating layer) with an area of ​​150mm×150mm and a thickness of 125μm. The graphene has been doped and the square resistance is 250Ω / □;

[0127] 2. Use screen printing equipment to print the silver paste electrode pattern on the transferred graphene, the shape of the pattern is as follows: image 3 As shown, the distance between the positive inner electrode and the negative inner electrode is 6mm, the length of the positive inner electrode and the negative inner electrode is 108mm, and the width is 1mm, a total of 15, the width of the positive bus bar and the negative bus bar is 8mm, and the thickness of the silver paste is 25μm;

[0128] 3. Bake the printed electrode layer in an oven to solidify the silver paste. The baking temperature is ...

Embodiment 2

[0139] In this embodiment, two layers of graphene are used as the conductive layer of the heating film, and the electrode layer is printed with silver paste.

[0140] 1. Transfer two layers of graphene as the conductive layer on the PET (first insulating layer) with an area of ​​120mm×120mm and a thickness of 125μm. The graphene has been doped and the square resistance is 120Ω / □;

[0141] 2. Use screen printing equipment to print the silver paste electrode layer on the transferred conductive layer, and the pattern shape is as follows: Figure 9 As shown, the outer diameter of the bus bar is 96mm, the inner electrode spacing is 6mm, the width is 1mm, the width of the bus bar is 8mm, and the thickness of the silver paste is 25μm;

[0142] 3. Bake the printed electrode pattern in an oven to solidify the silver paste. The baking temperature is 130°C for 40 minutes.

[0143] In this case, connect the lead wires to the positive and negative poles of the 5V power supply respectively...

Abstract

The invention relates to a chair cushion. A chair cushion, comprising: a heating film including a first insulating layer; a conductive layer formed on the surface of the first insulating layer; an electrode layer formed on the surface of the conductive layer and electrically connected to the conductive layer, The electrode layer includes a positive electrode and a negative electrode. The positive electrode includes a positive bus bar and a plurality of positive internal electrodes extending from the positive bus bar. The negative electrode includes a negative bus bar and a plurality of positive inner electrodes extending from the negative bus bar. a plurality of negative internal electrodes extending from the strip, the positive internal electrodes and the negative internal electrodes are alternately arranged and spaced apart from each other; and a second insulating layer is formed on the surface of the electrode layer; a chair cushion cover, the heating The film is accommodated in the chair cushion cover; and the power switch is electrically connected with the electrode layer of the heating film. The above-mentioned chair cushion has a heating function and can be powered by a lower voltage.

Description

technical field [0001] The invention relates to a chair cushion. Background technique [0002] With the development of society, people's requirements for quality of life are getting higher and higher. For example, chairs are often equipped with cushions for added comfort. Ordinary chair cushions are only filled with cotton batting in the cushion cover to keep warm. When the weather is cold, ordinary chair cushions cannot meet people's needs, but chair cushions with heating function can meet people's needs in winter. [0003] However, the existing chair cushions with heating function require a higher power supply voltage. On the one hand, once the high voltage leaks, it will cause an electric shock, and the safety performance is not good. demanding. Contents of the invention [0004] Based on this, it is necessary to provide a chair cushion with a heating function that can be powered by a lower voltage. [0005] A chair cushion, comprising: [0006] Heating film, inclu...
