Abstract

A gas detection purification device is disclosed and includes a main body, a purification unit, a gas guider, a gas detection module and a controlling-driving module. The main body includes an inlet, an outlet, an external socket and a gas-flow channel disposed between the inlet and the outlet. The purification unit is disposed in the gas-flow channel for filtering gas introduced through the gas-flow channel. The gas guider is disposed in the gas channel and located at a side of the purification unit. The gas is inhaled through the inlet, flows through the purification unit and is discharged out through the outlet. The gas detection module is plugged into or detached from the external socket. The controlling driving module is disposed within the main body and electrically connected to the gas guider to control the operation of the gas guider in an enabled state and a disabled state.
