[0020] By providing a purification structure, the first purification layer is a photocatalyst filter element layer, which can use photocatalyst materials to decompose harmful substances in the air such as formaldehyde and benzene, improving air quality. The photocatalyst can produce a catalytic effect under light conditions and decompose harmful substances in the air into harmless substances. The second purification layer is an activated carbon layer, which has excellent adsorption performance and can effectively remove pollutants such as odors, harmful gases, and volatile organic compounds in the air, realizing the functions of purifying air and performing secondary treatment on the air of the device and improving the working efficiency of the air exchange device during use;

[0021] By providing an exhaust structure, after the clean air enters the workshop body, the dirty air inside the workshop body can blow the baffle under the action of wind. The baffle and the workshop body are hinged through a connecting shaft. When the baffle is blown by the wind, a gap will be formed between its bottom end and the workshop body, and the dirty air can be discharged to the outside of the workshop body through the gap. Since the baffle can only rotate outwards, it can prevent gas from flowing back into the workshop body, realizing the functions of facilitating exhaust and preventing air from flowing back of the device and improving the working efficiency of the air exchange device during use.
