Gas exchange device

A gas exchange device for filtering a gas, comprising:

• a gas-intake channel comprising a gas-intake-channel inlet and a gas-intake-channel outlet;
• a gas-exhaust channel disposed at one side of the gas-intake channel and comprising a gas-exhaust-channel inlet and a gas-exhaust-channel outlet;
• a purification unit disposed in the gas-intake channel for filtering the gas passing through the gas-intake channel;
• a gas-intake guider disposed between the gas-intake-channel inlet and the purification unit for guiding and transporting the gas from the gas-intake channel inlet to the gas-intake-channel outlet;
• a gas-exhaust guider disposed in the gas-exhaust channel near the gas-exhaust-channel outlet for guiding and transporting the gas from the gas-exhaust-channel inlet to the gas-exhaust-channel outlet;
• a driving controller disposed in the gas-intake channel near the gas-intake guider for controlling enablement and disablement of the purification unit, the gas-intake guider and the gas-exhaust guider;
• and
• a gas detection main body disposed in the gas-intake channel near the gas-intake-channel inlet for detecting the gas introduced through the gas-intake-channel inlet and generating detection data.
