Vehicle-mounted fresh air system
Technical Field
The invention belongs to the field of air purification and the field of automobile accessories, and particularly relates to a vehicle-mounted fresh air system.
Background
The air pollution in the automobile is substantially higher than the indoor pollution degree, materials such as seats in the automobile can release substances such as formaldehyde which are harmful to human bodies for a long time, although most of the release amount does not exceed the standard, the substances can be enriched in the human bodies under the environment for a long time, and thus the substances can cause unrecoverable harm to the human bodies. The existing vehicle-mounted air purification system sucks gas in a vehicle, discharges the gas after passing through a filtering membrane, can only filter and adsorb tiny dust in the vehicle by the treatment, cannot remove harmful gas, can not change the gas composition in the vehicle by the purification of the internal circulation mode in the vehicle, and can cause oxygen deficiency of people in the vehicle by the long-term internal circulation. At present, some automobiles are also provided with vehicle-mounted fresh air systems, but the fresh air systems are only provided with filtering membranes at the inlets of the air conditioning systems to filter the externally-entering gases, and the purification effect of the fresh air systems is questionable.
