Purification device of exercise environment

A purification device of exercise environment, comprising:

• a main body having at least one gas inlet and at least one gas outlet;
• and
• a purification unit, a gas guider and a gas detection module disposed in the main body, wherein the gas detection module comprises a gas detection main part, the gas detection main part comprises a base, a piezoelectric actuator, a driving circuit board, a laser component, a particle sensor and an outer cover, wherein the base comprising:
• a first surface;
• a second surface opposite to the first surface;
• a gas-guiding-component loading region concavely formed from the second surface;
• the piezoelectric actuator accommodated in the gas-guiding-component loading region;
• the 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;
• the particle sensor positioned and disposed on the driving circuit board, electrically connected to the driving circuit board, and disposed at an orthogonal position and
• an outer cover covering the first surface of the base and comprising a side plate,
• wherein a gas in an exercise environment is introduced through the at least one gas inlet and filtered by the purification unit, the gas in the exercise environment is continuously transported by the gas guider, passed through the at least one gas inlet, flowed through the purification unit, and provided to a breathing region around a nose of an exerciser, wherein the gas detection module detects a gas information and a particulate cleanliness of the air in the exercise environment, and the particulate cleanliness of the gas in the breathing region of the exerciser reaches 0˜20 μg/m3 accordingly.
