The top cover 3 is located above the mounting groove 112. The cover plate is used to block the filter 2 from being visually observed by the user. The connecting posts 31 lift the top cover 3 to a certain height on the main body 1 so that an air duct 32 is formed between the top cover 3 and the main body 1. The design of the top cover 3 being inserted into the connecting holes 111 by the connecting posts 31 allows the top cover 3 to be removed from the main body 1, making it convenient for the user to replace the filter 2.
[0040] When the fan 14 is running, the air in the car enters the main body 1 from the top cover 3 and the air duct 32 of the main body 1. When passing through the filter 2, the filter 2 filters out dust, bacteria, odor and other pollutants in the air. The negative ion generator 126 purifies the air for the second time and then discharges it from the second vent 125, thereby achieving the task of air purification with simple components and reducing the size of the equipment.
[0041] The utility model provides a small air purifier. The main body draws air from the vehicle compartment through a fan. The air enters the space between the main body and the cover plate through the air duct and passes through the filter screen. The filter screen filters out pollutants such as dust, bacteria, and odor in the air. The fan discharges the filtered air from the second vent. The device filters the air in the vehicle compartment through the fan and the filter screen, which reduces the size of the device and reduces the space occupied in the vehicle compartment.
[0042] The cover is connected to the connection hole through the connecting column, so that the cover can be removed from the main body, allowing the user to remove the old filter and replace it with a new one, so that the device maintains efficient filtering capabilities.
