Description
Technical Field
The invention relates to the field of ultrasonic cleaning, in particular to a portable household ultrasonic transmitter for cleaning tableware and fruits and vegetables.
Background
The ultrasonic cleaner is an instrument for cleaning pollutants, and can be widely applied to the aspects of industry, national defense, biomedicine and the like by converting the acoustic energy of a power ultrasonic frequency source into mechanical vibration through a transducer to clean objects. The ultrasonic cleaning principle is that the transducer converts the acoustic energy of an ultrasonic frequency source into mechanical vibration, ultrasonic cavitation effect is generated in the propagation process of ultrasonic waves in the cleaning liquid, and micro-bubbles generated by ultrasonic cavitation generate micro-shock waves, micro-jet flow and local high temperature and high pressure when being collapsed, so that the cleaning of the solid surface immersed in the cleaning liquid is realized.
At present, most ultrasonic cleaners are of a tank type, namely, an ultrasonic transducer is fixed on the wall surface of a cleaning tank, so that ultrasonic irradiation is introduced into cleaning liquid in the tank, and the cleaner belongs to internal radiation type ultrasonic cleaning equipment. The cleaner has the advantages of high sound field intensity, good cleaning effect, large volume and unfavorable carrying and storage, so that the cleaner is mainly used in industrial production. In addition, the sound field distribution of the internal radiation type ultrasonic cleaning equipment is fixed, so that a cleaning blind area is easily formed, and the cleaning uniformity is poor.
At present, the development of portable household ultrasonic cleaning equipment is still in a starting stage, and in order to meet the requirements of the household cleaning equipment on portability, easy storage and the like, an external radiation type ultrasonic device is generally adopted, namely an ultrasonic transducer is fixed on a specific structural unit, and the ultrasonic unit is immersed in cleaning liquid to finish cleaning during cleaning. The common transducer is a piezoelectric ceramic plate or a single piezoelectric ceramic transducer, which is limited by the volume of the device. The piezoelectric ceramic plate has lower acoustoelectric conversion efficiency, so that the cleaning liquid has weaker hollow effect, and the cleaning effect is only distributed between 0 cm and 2cm away from the ultrasonic emission end face; moreover, the device needs to be manually held to be close to the stain end, so that the device is inconvenient; the cleaning efficiency is low, the time consumption is long, and the ideal cleaning effect on the surface with heavy greasy dirt is difficult to achieve. The single-piezoelectric ceramic transducer has improved sound-electricity conversion efficiency, but still needs to be manually held to clean certain dirt ends, has poor uniformity of sound field, and cannot effectively clean objects with large volume and more dirt.
In summary, although the tank type ultrasonic cleaning device has mature technology, high sound field intensity and ideal cleaning effect, the tank type ultrasonic cleaning device is difficult to meet the requirements of household cleaning devices in the aspects of portability and sound field uniformity. However, the external radiation type ultrasonic cleaning device is not mature at present, and no better solution exists in the aspects of sound field intensity, sound field uniformity, cleaning efficiency, portability and the like.
