In the internal circulation state, the ventilation channels inside and outside the car are closed, forming an air flow circulation inside the vehicle. When the fan is turned on, the inhaled air flow only comes from inside the car. The function of the internal circulation device is to effectively remove dust, odor and harmful substances in the air, improve the air quality, and maintain a stable temperature in the car. The internal circulation device can ensure the continuous purification and circulation of the air. These devices help reduce resource waste and improve system stability and service life. The on-board air purifier uses internal circulation technology to not only improve the air quality in the car, but also ensure the health of the passengers and driving comfort.

The first motor 205 drives the first fan blade 202 to rotate through the connecting rod 204 to form suction, and air is sucked in from the first fan 2. The function of the first fin 301 is to increase the temperature conversion area between the first U-shaped tube 303 and the air.

[0025] Among them, the evaporator 3 includes a first fin 301, a first fixed plate 302, a first U-shaped tube 303, an expansion valve 304, and a compressor 305.

The evaporator 3 converts liquid refrigerant into gas, absorbs heat in the vehicle, and the flowing air passes through the evaporator 3 and undergoes heat conversion with the refrigerant in the first U-shaped tube 303, and the air becomes cold. At the same time, the cold air passes through the dust collecting hood 4 and the air outlet pipe 404 into the interior of the vehicle, and the dust and impurities in the air will be blocked by the dust collecting hood 4 and accumulate over time. In addition, the vibrator 405 can be started regularly to shake off the dust attached to the inner wall of the air outlet pipe 404.
