[0001] The present invention relates to the technical field of air purification equipment, and in particular to a vehicle-mounted air purification system start-stop control method. Background Art

[0002] As cars gradually become a consumer product in every household, people's requirements for the in-car environment are becoming higher and higher. The air circulation is poor due to the small and closed space in the car. Especially when the air conditioner is used in the car, this situation will be aggravated, causing harmful gases such as particulate pollutants, formaldehyde, TVOC in the air, and formaldehyde, benzene and other harmful gases emitted by plastics and leather products in the car to exist in the car for a long time, which will seriously endanger the health of passengers.

[0003] At present, most of the methods for starting the vehicle air purifier device are to manually turn it on or off by the driver or passengers, that is, the user needs to pay attention to the changes in the air quality outside the vehicle at all times to manually turn on the vehicle air purifier device. However, people generally cannot judge the quality of the air well with their eyes, so the method of manually operating the air purifier device cannot play a good role in protecting human health. In addition, in daily life, this method of manually operating the air purifier device generally causes people to turn on the air purifier device and start the purification work after getting in the car, and cannot provide a clean in-car environment before getting in the car, resulting in purification while driving, and people will still inhale a large amount of harmful substances, threatening health. Summary of the invention

[0004] The purpose of the present invention is to provide a control method for the start-stop of a vehicle-mounted air purification system, using a vehicle-mounted ECU to record the status log of the start button, and sending the status log to the control MCU of the air purification device through the communication connection of the vehicle-mounted Bluetooth and the control Bluetooth. And the control MCU can also identify the status log of the start button, wherein the status log includes two states of start and close. When the control MCU recognizes the start state of the start button, a switch closing instruction will be sent to the switch of the control circuit, and the switch closing instruction is an instruction to close the switch immediately; when the control MCU recognizes the closed state of the start button, a switch disconnection instruction will be sent to the switch of the control circuit, and the switch disconnection instruction is an instruction to disconnect the switch after 30 minutes, which solves the inconvenience of the manual operation method of the air purification device, and the problem that it cannot protect human health well, and solves the problem that people cannot have a clean in-vehicle environment before getting on the car, which leads to purification while driving, so that people still breathe in a large amount of harmful substances.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:
