1. A mobile power device capable of detecting gas, comprising:
a main body having a ventilation opening, at least one connection port and an accommodation chamber, wherein the ventilation opening is in communication with the accommodation chamber to allow gas to be introduced into the accommodation chamber;
at least one gas detection module disposed within the accommodation chamber of the main body, and configured to transport the gas into an interior thereof, so as to detect a particle size and a concentration of suspended particles contained in the gas and output detection information;
a driving and controlling board disposed within the accommodation chamber of the main body, wherein the gas detection module is positioned and disposed on the driving and controlling board and electrically connected to the driving and controlling board;
a power module positioned and disposed on the driving and controlling board, electrically connected to the driving and controlling board and capable of storing an electric energy and outputting the electric energy outwardly; and
a microprocessor positioned and disposed on the driving and controlling board and electrically connected to the driving and controlling board, wherein the microprocessor enables the gas detection module to detect and operate by controlling a driving signal to be transmitted to the gas detection module, and converts the detection information of the gas detection module into a detection data, wherein the detection data is stored, externally transmitted to an mobile device for processing and application, and externally transmitted to an external device for storing

a base 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 concavely formed from the second surface and disposed adjacent to the laser loading region, wherein the gas-inlet groove comprises a gas-inlet and two lateral walls, the gas-inlet is in communication with an environment outside the base, and a transparent window is opened on the lateral wall and is in fluid communication with the laser loading region;
a gas-guiding-component loading region concavely formed from the second surface and in 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 concavely formed from the first surface, spatially 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 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 covering and attached to the second surface of the base;
a laser component positioned and disposed on the driving circuit board, 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, thereby forming an orthogonal direction with the gas-inlet groove;
a particle sensor positioned and disposed on the driving circuit board, electrically connected to the driving circuit board, and disposed at an orthogonal position where the gas-inlet groove intersects the light beam path of the laser component in the orthogonal direction, so that suspended particles passing through the gas-inlet groove and irradiated by a projecting light beam emitted from the laser component are detected; 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 inlet path is collaboratively defined by the gas-inlet groove and the driving circuit board, and an outlet path is collaboratively defined by the gas-outlet groove, the outer cover and the driving circuit board, so that the gas is inhaled from the environment outside base by the piezoelectric actuator, transported into the inlet path through the inlet opening, and passes through the particle 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 outlet path through the ventilation hole and then discharged through the outlet opening.
