Embodiment 1

[0028] see figure 1 , an ultrasonic air wiper, characterized in that the ultrasonic air wiper includes an ultrasonic system and an air system;

[0029] The ultrasonic system includes ultrasonic transducers 9 positioned on both sides of the front windshield; the ultrasonic transducer includes an upper metal cover plate, a negative electrode sheet, an upper piezoelectric ceramic sheet, a positive electrode sheet, and a lower piezoelectric ceramic sheet , lower metal cover plate, prestressed screw and insulating tube, upper metal cover plate, negative electrode sheet, upper piezoelectric ceramic sheet, positive electrode sheet, lower piezoelectric ceramic sheet and lower metal cover plate are arranged in sequence, and passed through the prestressed screw fixed, the insulating tube is located between the piezoelectric ceramic sheet and the prestressed screw, and the ultrasonic transducer is connected to the high-frequency oscillating voltage power supply through a wire; when raind...

Embodiment 2

[0037] see figure 2 , as an improvement of the present invention, the rain removal control system 6 of the air wiper includes a numerical input module 601 for inputting a fixed value of rainfall; a numerical comparison module 602 for judging the rainfall value fed back by the rain sensor and the fixed value The size relationship of the air outlet; the air outlet control module 603 controls the opening or closing of the upper air outlet and the lower air outlet according to the result of the numerical comparison module. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0039] As an improvement of the present invention, the outer side of the ultrasonic transducer of the ultrasonic air wiper is provided with a waterproof and heat-insulating protective shell; this ensures that the ultrasonic transducer can work normally in a humid or outdoor environment with a large temperature difference. The rest of the structures and advantages are exactly the same as in Embodiment 1.

Abstract

The invention relates to the field of auto spare parts, and particularly relates to an ultrasound air windshield wiper. The ultrasound air windshield wiper comprises an ultrasound system and an air system. Moisture in front windshield of an automobile is got ridden of by triple functions of ultrasound, wind force and high temperature. With the triple functions, the ultrasound air windshield wiper can not only remove stains in the windshield, but also have a better rainwater eliminating effect, and can remove fog in the inner side of the windshield through heated air at the same time; besides, through a rainwater eliminating control system, opening and closing of an upper air outlet and a lower air outlet are controlled according to different rainfall; meanwhile, a control valve is used to control power of an ultrasonic transducer, therefore efficiency in rainwater eliminating is improved, and energy is saved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an ultrasonic air wiper. Background technique [0002] On rainy days, when the car is driving, the raindrops hit the front windshield, which seriously affects the driver's sight and poses a great safety hazard. The traditional car wiper uses the wiper strip to swing back and forth on the front windshield to refresh the raindrops on the glass surface, so that the driver's vision is clear and wide. The heavier the rain, the higher the frequency of the wiper movement, but the work of the wiper strip will still be To a certain extent, it affects the driver's line of sight. At the same time, because the windshield is easy to stick to the mucus that is not easy to dissolve in water, etc., the wiper cannot wipe off the water stains on the glass, which affects the vision and endangers driving safety. [0003] Ultrasound is a sound wave with a frequency higher than 20,000 Hz. It has good direc...
