Claim 0:
1. A method for preventing and handling in-car air pollution, applicable for dealing with air pollutant by gas exchanging and filtering of a polluted gas in an interior space of a car, wherein the method comprises:
providing an out-car gas detector to detect a polluted gas outside the car and transmit an out-car gas detection data;
providing an in-car gas detector to detect the polluted gas in the interior space of the car and transmit an in-car gas detection data;
providing an in-car gas exchange system for controlling and determining if it is needed to introduce a gas outside the car into the interior space of the car, wherein the in-car gas exchange system comprises a cleaning unit and a control driving circuit; the cleaning unit is provided for filtering and purifying the polluted gas in the interior space of the car, and the control driving circuit receives the out-car gas detection data and the in-car gas detection data and compares the out-car gas detection data with the in-car gas detection data; and
providing an intelligent selection conducted by the control driving circuit for introducing the gas outside the car by the in-car gas exchange system after the control driving circuit compares the out-car gas detection data with the in-car gas detection data;
wherein the in-car gas exchange system has at least one gas inlet and at least one gas outlet the gas outside the car enters into the in-car gas exchange system through the at least one gas inlet and passes through the cleaning unit for filtering and purifying, and then the gas is introduced into the interior space of the car through the at least one gas outlet;
the at least one gas inlet is connected to an inlet channel and comprises an inlet valve for opening or closing the at least one gas inlet; the in-car gas exchange system further comprises a gas-exchange inlet, a gas-exchange channel, and a gas-exchange outlet; the gas-exchange inlet is connected to the gas-exchange channel, the gas-exchange channel is in communication with the gas-exchange outlet and the inlet channel; the gas-exchange outlet comprises an outlet valve for opening or closing the gas-exchange outlet; and
the polluted gas in the interior space of the car leaving from the outlet valve does not pass through the at least one gas outlet.
