preparation example Construction

[0109] 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.

[0110] Preferably, the thickness of the first adhesive layer 213 and the second adhesive layer 217 is 25-75 μm.

[0111] see Figure 6 , the structure of the waist support in another embodiment is substantially the same as that of the waist support 1, the difference is that in the illustrated embodiment, the heating film 410 of the waist support 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 adhesi...

Abstract

The invention relates to a waist support. The waist support comprises a waist support body, a heating film arranged on the waist support body and a connecting wire. The heating film comprises a first insulating layer, a conducting layer, electrode layers and a second insulating layer. The conducting layer is formed on the surface of the first insulating layer. The electrode layers are formed on the surface of the conducting layer and electrically connected with the conducting layer. The electrode layers comprise positive electrodes and negative electrodes. The positive electrodes comprise positive bus bars and a plurality of positive internal electrodes extending from the positive bus bars. The negative electrodes comprise negative bus bars and a plurality of negative internal electrodes extending from the negative bus bars. The positive internal electrodes and the negative internal electrodes are arranged alternatively in a spaced mode. The second insulating layer is formed on the surface of one electrode layer. The connecting wire is electrically connected with the electrode layers of the heating film. The waist support has a heating function and can be powered up through low voltage.

Description

technical field [0001] The invention relates to a waist support. Background technique [0002] At present, waist protectors are mostly made of materials with good heat resistance such as cotton, velvet or fur to keep the waist warm. When in use, these waist protectors cannot release heat by themselves, but rely on accumulating the heat emitted by the human body to keep warm. When used in a cold environment, these waist protectors have a very limited effect on keeping the waist warm, and it is difficult to resist external cold. invasion. When the waist is injured, it is also necessary to apply heat to the waist to promote blood circulation and relieve pain, so a waist support with heating function is very necessary. [0003] Heating waist protectors generally have resistance wires installed on the body of the waist protector to generate heat. However, metal heating wires as resistance wires require a higher power supply voltage. Once leakage occurs, it will endanger life an...
