Ultrasonic washing device

Abstract

An ultrasonic cleaning device that sprays washing liquid from the tip of the nozzle to the object to be washed or the place to be washed for washing. In order to efficiently transmit the ultrasonic vibration generated by the ultrasonic vibrator to the washing liquid, the ultrasonic transmission body combined with the ultrasonic vibrator A part protrudes toward the cavity of the nozzle filled with washing liquid. In addition, its cross-sectional area gradually becomes smaller toward the tip portion of the ultrasonic transmitting body, so that ultrasonic vibrations are converged to the end surface of the ultrasonic transmitting body. In addition, the length of the ultrasonic vibrator and the ultrasonic transmission body is equal to an integer multiple of the half-wavelength length of the ultrasonic standing wave vibration, and the end face of the ultrasonic transmission body that radiates ultrasonic waves to the cleaning liquid is arranged at the position of the abdomen of the ultrasonic standing wave vibration with the largest amplitude. superior.

Description

technical field [0001] The present invention relates to a washing device using ultrasonic vibration, and more particularly, to an ultrasonic washer for washing objects to be washed or places to be washed by spraying washing liquid (washing) propagating ultrasonic vibration energy from nozzles. Background technique [0002] For example, in the Japanese Patent Application Publication No. 6-218337, it is proposed that Figure 37 The illustrated ultrasonic cleaning device 520 is an ultrasonic cleaning device 520 that sprays cleaning liquid given energy of ultrasonic vibration from a nozzle to clean the object to be washed or the place to be washed. [0003] Existing ultrasonic cleaning device 520 is by drive circuit 521, by the ultrasonic vibrator 522 driven by drive circuit 521, is used to transmit the ultrasonic transmission body 523 of the ultrasonic vibration that ultrasonic vibrator 522 produces, the cone (cone) that is connected with ultrasonic transmission body 523 ) 524,...

AI Technical Summary

Problems solved by technology

Therefore, since the transmission efficiency of ultrasonic vibration is low, if the output of the ultrasonic vibrator 522 is small, sufficient air bubbles will not be generated in the washing liquid sprayed from the nozzle 525, and sufficient washing by cavitation may not be obtained. force

On the other hand, if the output of the ultrasonic vibrator 522 is too high, as in the ultrasonic humidifier, the cleaning liquid becomes misty, and there is a high possibility that sufficient cleaning power cannot be obtained.

[0005] In addition, the existing ultrasonic cleaning device 520, as described in the above publication, is, for example, a large ultrasonic cleaning device for cleaning the side wall of a building, and the driving circuit 521 is separately provided from the main body, etc., and is not suitable for the user to hold it.
