Description
Technical field
The present invention relates to auto parts field more particularly to a kind of ultrasonic air rain brush.
Background technique
On rainy day, in the process of moving, rain spatters seriously affect the sight of driver, deposit automobile on front windshield
In very big security risk.Orthodox car wiper is swung back and forth on front windshield using windscreen wiper item, refreshes glass surface rain
Drop, keeps getting a clear view for motorist open, rain is bigger, and wiper motion frequency is higher, but the work of windscreen wiper item still can
The sight of driver is influenced to a certain extent.Simultaneously as being easy to be stained with mucus for being not readily dissolved in water etc., rain on windshield
Curette can not scrape water stain on glass clean, influence the visual field, jeopardize traffic safety.
Ultrasonic wave is a kind of sound wave of the frequency higher than 20000 hertz, its good directionality, penetration capacity is strong, is easily obtained
Compared with the sound energy of concentration, propagation distance is remote in water, can be used for ranging, tests the speed, cleans, welding, rubble, sterilizing etc..
Ultrasonic wave is a kind of density interphase, the high frequency waves of radiation propagation, so that liquid at high speed be made back and forth to shake in cleaning solution
It is dynamic.Have little time to supplement due to the liquid of surrounding in the negative pressuren zone of vibration, forms countless slight vacuum bubbles, and in zone of positive pressure,
Micro-bubble is closed suddenly under stress, since mutually collision generates powerful surge waveform at most between liquid in closing course
The high instantaneous high pressure up to thousands of a atmospheric pressure, acts on cleaned article；Greasy, the impurity being adsorbed on article are connecting
Continue and be detached from rapidly under continuous Instantaneous High Pressure, to reach clean purpose；The above process is ultrasonic cavitation.
On the other hand, theoretical research show amplitude under the same conditions, the energy and vibration frequency of an object vibration
Directly proportional, when ultrasonic wave is propagated in the medium, the frequency of medium particle vibration is very high, thus energy is very big, if ultrasonic wave
It is passed through in water, violent vibration can make water be broken into many small droplets, and here it is the principles of ultrasonic humidifier.
Summary of the invention
It is an object of the invention to solve wiper in the prior art to influence driver's seat, water stain halfway technology is removed
Problem.
To achieve the goals above, technical scheme is as follows,
A kind of ultrasonic air rain brush, which is characterized in that the ultrasonic air rain brush includes ultrasonic system and air system；
The ultrasonic system includes the ultrasonic transducer positioned at front windshield two sides；The ultrasonic transducer includes
