The smokeless barbecue car works the same as the lampblack purifier, except that there is an extra fan. The fan is installed under the grill of the smokeless barbecue car. Under the suction of the fan, the smoke generated by barbecue enters the barbecue car through the smoke collecting plate above the barbecue grill, and there is a high-voltage electrostatic field in the barbecue car to absorb the smoke. After being purified by high-voltage electric field, the oil fume is separated by electrolysis, then filtered to the oil absorption tray, and the purified air is exhausted.

Ordinary barbecue cars simply do not have the above functions.
