Claim 2:
3. The gas detection and cleaning system for the vehicle according to claim 2, wherein the gas detection main body comprises:
the base comprising:
the gas-guiding-component loading region having four positioning protrusions disposed at four corners thereof; and
an outer cover covering the first surface of the base and comprising a side plate, wherein the side plate has an inlet opening spatially corresponding to the gas-inlet and an outlet opening spatially corresponding to the gas-outlet respectively,
wherein the first surface of the base is covered with the outer cover, and the second surface of the base is covered with the driving circuit board, so that an gas-inlet path is defined by the gas-inlet groove, and an gas-outlet path is defined by the gas-outlet groove, wherein the gas is inhaled from the environment outside the base by the piezoelectric actuator, transported into the gas-inlet path defined by the gas-inlet groove through the inlet opening, and passes through the particulate sensor to detect the concentration of the suspended particles contained in the gas, and the gas transported through the piezoelectric actuator is transported out of the gas-outlet path defined by the gas-outlet groove through the ventilation hole and then discharged through the outlet opening.
