1. A purification device of a baby carriage applied in the baby carriage, and comprising:
a main body mounted on the baby carriage and comprising at least one inlet and at least one outlet;
a purification unit disposed in the main body for filtering a gas introduced into the main body through the at least one inlet;
a gas guider disposed in the main body and adjacent to the at least one outlet, wherein the gas outside the main body is inhaled by the gas guider and flows through the purification unit for filtering and purifying, so that a purified gas is generated by filtering and is discharged out through the at least one outlet; and
a gas detection module disposed in the main body for detecting a particle concentration of suspended particles contained in the purified gas filtered through the purification unit, wherein the gas detection module comprises a gas detection main part, and the gas detection main part comprises:
a base comprising:
a first surface;
a second surface opposite to the first surface; and
a gas-guiding-component loading region concavely formed from the second surface;
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, and electrically connected to the driving circuit board;
a particle sensor positioned and disposed on the driving circuit board, and electrically connected to the driving circuit board; and
an outer cover covering the first surface of the base;
wherein the main body is a directional gas-guiding device, which is fixedly combined with a fixed frame of the baby carriage, wherein a directional guiding element is disposed in the at least one outlet of the main body, so that a purified gas generated by directional filtering is discharged from the at least one outlet, and the gas guider is constantly controlled to operate and export the gas at an airflow rate within 3 minutes to reduce the particle concentration of the suspended particles contained in the purified gas to less than 0.75 μg/m3, so that the purified gas is provided by filtration to a baby breathing in the baby carriage.
