A miniature gas detection and purification device is disclosed for a user to carry with him, and includes a main body, a purification module, a gas guider and a gas detection module. The gas detection module detects the gas in the environment surrounding the user to obtain a gas detection datum, and controls the gas guider to be operated according to the gas detection datum, so that gas is inhaled into the main body and flows through the purification module for filtration and purification, and the gas purified is finally guided to an area nearby the user. 1. A miniature gas detection and purification device , comprising:a main body for a user to carry with him, comprising at least one inlet, at least one outlet, a detecting inlet, a detecting outlet and a gas-flow channel, wherein the gas-flow channel is disposed between the at least one inlet and the at least one outlet;a purification module disposed in the gas-flow channel of the main body;a gas guider disposed in the gas-flow channel of the main body and located at a side of the purification module, wherein gas is inhaled by the gas guider through the at least one inlet, flows through the purification module for filtration and purification, and is discharged out through the at least one outlet;a gas detection module disposed in the main body, spatially corresponding to the detecting inlet and the detecting outlet for detecting the gas to obtain a gas detection datum, and comprising a gas detection main part, a microprocessor and a communicator, wherein the gas detection main part detects the gas introduced from the outside of the main body to obtain the gas detection datum, the microprocessor receives the gas detection datum to calculate, process and control the enablement and disablement of the gas guider, and the communicator receives the gas detection datum from the microprocessor;wherein the microprocessor controls operations the enablement of the gas guider according to the gas detection datum detected by ...
