The utility model is a motor vehicle heater with a dustproof function. By providing a heater assembly and a dustproof assembly, the device can improve the heat output effect of the heater, effectively ensure the air circulation and heating inside the motor vehicle, and has a good dustproof effect. Dust can be collected in a centralized manner to prevent dust from affecting the normal use of the heater, thereby increasing the service life of the heater. However, the existing motor vehicle heater still has the following shortcomings: 1. The installation operation between the existing motor vehicle heater and the motor vehicle is relatively cumbersome, and most of them need to be completed with the help of external tools and bolts.
