The application provides an air purification method, device, equipment, system, vehicle and storage medium. The air purification method comprises the following steps: acquiring a first air quality and an oxygen concentration in a vehicle; acquiring a second air quality outside the vehicle when the first air quality is less than a first air quality threshold and the oxygen concentration is less than an oxygen concentration threshold; and closing the vehicle window and controlling a first purification unit to start working when the second air quality is greater than the first air quality, so that the external air is purified and then sucked into the vehicle, and fresh air is supplemented in time, so that the air in the vehicle can be purified in time, and the comfort of the people in the vehicle is improved.

The utility model relates to the technical field of shoe production, and discloses a toe cap thermal forming device which comprises a workbench assembly, a heating assembly, a shaping assembly and a purifying assembly, the heating assembly is installed on one side of the top of the workbench assembly, the shaping assembly is installed on the other side of the heating assembly, and the purifying assembly is installed on the workbench assembly. And the purifying assembly is mounted on the rear side of the shaping assembly. Due to the fact that the purification assembly is installed on the device, generated harmful gas can be purified in time when shoes are heated and shaped, and pollution to the air environment and influence on health of workers can be avoided.
