Abstract

A method of preventing air pollution in a vehicle is disclosed. Firstly, an out-car gas detection device, an in-car gas detection device and a purification device are provided to detect the air pollution and transmit a respective gas detection datum to a connection device. An in-car gas exchange system is provided for intelligently selecting and controlling a gas outside the vehicle to be introduced or not introduced into the inner space of the vehicle. The connection device receives and compares the gas detection data, so that the connection device selectively transmits a control instruction to the in-car gas exchange system and the purification device, and the air pollution in the inner space of the vehicle is exchanged and filtered, so as to provide clean, safe and breathable air.

First claim

What is claimed is:

1. A method of preventing air pollution in a vehicle for exchanging and filtering air pollution in an inner space of the vehicle and the method comprises:
a) providing an out-car gas detection device to detect the air pollution outside the vehicle and transmit an out-car gas detection datum;
b) providing an in-car gas detection device to detect the air pollution inside the vehicle and transmit an in-car gas detection datum;
c) providing an in-car gas exchange system for selecting and controlling the introduction of a gas outside the vehicle into the inner space of the vehicle;
d) providing at least one purification device, wherein the at least one purification device comprises a purification unit, a gas guider and a gas detection module, wherein the purification unit is disposed inside the at least one purification device for filtering the air pollution introduced into the at least one purification device, wherein the gas guider disposed inside the at least one purification device for inhaling the air pollution in the inner space of the vehicle to flow through the purification unit for filtering and purifying, wherein the gas detection module is configured to detect filtered air flew through the purification unit and transmit an inside-device gas detection datum for selecting and controlling an activation of filtering the air pollution in the inner space of the vehicle; and
e) providing a connection device to receive and compare the out-car gas detection datum, the in-car gas detection datum and the inside-device gas detection datum, so that the connection device selectively transmits a control instruction to the in-car gas exchange system and the gas detection module of the at least one purification device for enabling the gas guider, and the air pollution in the inner space of the vehicle is exchanged and filtered, wherein the connection device is a mobile device.

2.
