The principle of the car seat heater is to heat the seat through the resistance wire inside the seat, so that the seat gradually heats up in a short period of time. There are no safety hazards in the use of seat heating, and the internal materials are not easy to cause short circuits, open circuits and aging even in harsh use environments. Improves the discomfort caused by the cold seat after not opening the seat for a long time in winter. The basic structure of the seat heater is: the lower layer is a layer of non-woven fabric, the heating wire is arranged on the non-woven fabric, the heating wire is fixed on the non-woven fabric with a fixed belt, the knitted fabric is covered on the fixed belt, and the knitted fabric is sewn into a shape similar to the heating place of the seat, and sewn in the seat cover. In order to improve the comfort of passengers in the car, the heating temperature of the seat is adjusted within the necessary range, and two temperature regulators are arranged in the seat heating pad: (1) 505 off, 305 on; (2) 435 off, 235 open. The backrest heater is connected to the seat heater's power supply via a connector. The seat cushion heater is powered by a connector to the dash harness and then to the battery power via the seat heating switch, fuse, and ignition. Things to keep in mind when using a heated seat: 1. The seat heating device can only work when the ignition switch is turned on; 2. In order to ensure the heating part of the seat heating device, please do not kneel on the seat or apply spot load to the seat surface and backrest; 3. If the on-board voltage decreases, the seat heating device will automatically turn off to ensure that sufficient electrical energy is supplied to the engine adjustment system; 4. Turn off the heating or ventilation of the seat immediately after stopping to avoid the next start and excessive power load; 5. Do not install too thick cushions on the heated seat, so as to avoid overheating and low temperature of the seat, which will affect the failure; 6. Turn on the seat heating switch after starting the engine, which can effectively save battery energy and prolong battery life. The main projects are divided into three categories: various electric heating heating sheets, mobile electric heating and warmth series, and mobile electric heating physiotherapy and health care series. First, various high and low voltage heating sheet product categories include automobile cushion heating sheet, automobile steering wheel electric sheet, automobile battery heating sheet, and various difficult heating sheets for automobile exhaust treatment; Second, the types of mobile electric heating series products include: electric gloves, electric heating clothing, electric heating shoes, electric heating insoles, etc.; Escort you in the cold winter, whether you go to work or play outdoor sports, you can radiate heat energy with you. Third, the mobile electrothermal physiotherapy health care series includes: electrothermal physiotherapy health care waist support, electric physiotherapy knee pads, electric physiotherapy health care neck support, electric physiotherapy health care shoulder pads and so on...
