1. A gas detection and cleaning system for a vehicle, comprising:
an external modular base comprising an external power connector, a power module, at least one first external connection port, at least one second external connection port and a driving and controlling circuit, wherein the external power connector is adapted to connect with vehicle power source to provide an operation power to the power module, wherein the at least one first external connection port and the at least one second external connection port are electrically connected to the power module respectively, so as to allow the at least one first external connection port and the at least one second external connection port to connect externally and provide a power source and transmit an information datum, wherein the at least one first external connection port and the at least one second external connection port are connected through the driving and controlling circuit for communication connection, so that the information datum received by the at least one first external connection port is transmitted to the driving and controlling circuit, processed and converted into an actuation information datum, and the actuation information datum is externally outputted through the at least one second external connection port;
a gas detection module connected to the at least one first external connection port to provide the power for operations, so as to detect a gas in an inner space of the vehicle and output the information datum in regard to the gas detection to the at least one first external connection port, wherein the information datum is transmitted through the at least one first external connection port to the driving and controlling circuit, processed and converted into the actuation information datum for externally outputting through the at least one second external connection port, wherein the gas detection module comprises:
a housing;
a gas detection main body disposed within the housing for detecting gas introduced from an outside of the housing to obtain the information datum in regard to the gas detection and comprising:
a first surface;
a second surface opposite to the first surface;
a laser loading region hollowed out from the first surface to the second surface;
a gas-inlet groove recessed from the second surface and disposed adjacent to the laser loading region, wherein the gas-inlet groove comprises a gas-inlet, in fluid communication with an environment outside the base, and two lateral walls, and a transparent window is opened on the two lateral walls and is in fluid communication with the laser loading region;
a gas-guiding-component loading region recessed from the second surface and in fluid communication with the gas-inlet groove, wherein a ventilation hole penetrates a bottom surface of the gas-guiding-component loading region; and
a gas-outlet groove recessed from the first surface corresponding to the bottom surface of the gas-guiding-component loading region, and hollowed out from the first surface to the second surface in a region where the first surface is not aligned with the gas-guiding-component loading region, wherein the gas-outlet groove is in fluid communication with the ventilation hole, and a gas-outlet is disposed in the gas-outlet groove and in fluid communication with the environment outside the base;
a piezoelectric actuator accommodated in the gas-guiding-component loading region;
a driving circuit board covered and attached to the second surface of the base;
a laser component positioned and disposed on and electrically connected to the driving circuit board, and accommodated in the laser loading region, wherein a light beam path emitted from the laser component passes through the transparent window and extends in a direction perpendicular to the gas-inlet groove; and
a particulate sensor positioned and disposed on and electrically connected to the driving circuit board, and disposed at an orthogonal position where the gas-inlet groove intersects with the light beam path of the laser component, so that suspended particles passing through the gas-inlet groove and irradiated by a projecting light beam emitted from the laser component are detected;

a processor control circuit unit integrally packaged with the gas detection main body in electrical connection; and
an external connector disposed on the processor control circuit unit and integrally packaged in electrical connection; and
a cleaning device comprising an external port connected with the at least one second external connection port to receive the actuation information datum outputted from the at least one second external connection port, wherein the cleaning device is controlled to be actuated or turned off according to the actuation information datum.
