With the increasing number of cars and their wider uses, the harmful substances brought by cars have also attracted attention, especially because trucks often travel in highly polluted areas, and the air quality inside the car has attracted much attention. The air quality inside the car directly affects the comfort and health of passengers. Air pollution inside the car is cumulative, long-term and diverse. Long-term inhalation of harmful substances may cause symptoms such as dizziness, nausea, sneezing, and even cause more serious diseases. Therefore, a device that can ventilate and purify the air inside the car is designed and produced to purify harmful substances and spread fresh air;

[0003] The existing ventilation air purification device is difficult to clean and maintain when in use. Long-term accumulation of impurities will cause the air sucked in by the fan of the main ventilation component to be unable to enter the cargo hold, and the rotating parts will be blocked and unable to rotate normally. In severe cases, the fan will be damaged, thereby increasing maintenance costs and usage costs. In addition, since the fan faces the outside, rainwater can easily enter the inside of the casing on rainy days and flow to the fan and motor output shaft, affecting the operation and service life of the motor.
