1. An external gas detecting device, comprising:
a casing;
a gas detection module disposed in the casing and detecting a gas transported into the casing to generate a gas information; and
an external connector connected to and disposed on the casing, wherein the external connector includes a plug, and can be plugged in an external receptacle, which is used to be connected to an external power supply so as to enable the gas detection module, and is used to transmit the gas information so as to achieve the outward transmission of the gas information, wherein the gas detection module comprises a base, a piezoelectric actuator, a driving circuit board, a laser component, a particle sensor and an outer cover, wherein the base comprises:
a first surface;
a second surface opposite to the first surface; and
a gas-guiding-component loading region concavely formed from the second surface and in communication with a gas-inlet groove,
wherein the piezoelectric actuator is accommodated in the gas-guiding-component loading region, the driving circuit board covers and attached to the second surface of the base, the laser component is positioned and disposed on the driving circuit board, is electrically connected to the driving circuit board, and is accommodated in the laser loading region, the particle sensor is positioned and disposed on the driving circuit board, is electrically connected to the driving circuit board, and is disposed at an orthogonal position, and the outer cover covers the first surface of the base and comprises a side plate.
