Description

Technical Field

[0001] The utility model relates to the field of air purification devices, in particular to an air purification device for a cab of an engineering vehicle. Background Art

[0002] The main reasons why the engineering vehicle cab needs air purification are as follows: There is often a lot of dust and particulate matter in the engineering operation environment. Entering the cab will affect the driver's health and vision.

[0003] For this reason, engineering vehicle drivers usually install a vehicle-mounted negative ion air purifier inside the driving compartment to purify the air inside the cab. The working principle of the vehicle-mounted negative ion air purifier is: through the negative ion generator, a large number of electrons are released using technologies such as high-voltage corona. These electrons combine with molecules such as oxygen in the air to form negatively charged air negative ions. Negative ions have the function of adsorbing and neutralizing pollutants in the air. They can attract tiny particles in the air (such as dust, pollen, smoke, etc.) and condense into larger particles, making them easier to be captured by filters or naturally settle;

[0004] The vehicle-mounted negative ion air purifier is usually installed inside the cup holder inside the cab. The size of the cup holder is not compatible with the vehicle-mounted negative ion air purifier. When the engineering vehicle moves on a rugged road, the purifier shell and the inner wall of the cup holder are prone to collision, generating noise, affecting the driver's driving mood, and reducing the service life of the purifier.
