Description

The present invention relates to the field of automobile parts technology, and specifically is a cleaning device for license plates for automobiles.

When driving a car in the rain or on a muddy road, it is often the case that the license plate number is not clearly visible due to too much sludge, and when driving the vehicle, the pressure at the tail of the car is low. In addition, there is a "Wake Vortex", which makes it easy for dust to stick to the rear part of the car, and existing license plate cleaning devices are generally mounted on the outside of the car, affecting the appearance of the car. By adopting the water wiping method, the license plate after cleaning is moist, and dust is more likely to adhere to the license plate.
