Ultrasonic generator

Abstract

The present invention discloses an ultrasonic generator and relates to the field of ultrasonic cleaning. The ultrasonic generator mainly comprises an electronic box, a water storage tank, a cleaning tank, a jolting plate disposed at the bottom of the cleaning tank, and a water level control device. The water level control device comprises a siphon, a floater disposed in the cleaning tank, a waterlevel raising part and a control knob. The water level raising part comprises a sleeve having an upper end communicating with the siphon, a piston in the sleeve, and a crank. The piston is connected to the crank by means of a connecting rod. A water inlet pluggable by a sidewall of the piston is arranged on the sidewall of the sleeve. A first one-way valve is arranged on the piston and a second one-way valve is arranged on a lower portion of the sleeve. A valve core capable of blocking the siphon is disposed in a bent section of the siphon. The floater is located below the valve core and capable of pressing against the valve core upwards. A push switch is disposed on the control knob. The push switch changes over once per revolution of the control knob. A contact switch is disposed at thebottom of the valve core. The push switch, the contact switch and the electronic box are connected in series. The ultrasonic generator is capable of avoiding misoperation.

Description

technical field [0001] The invention relates to the field of ultrasonic cleaning, in particular to an ultrasonic generator. Background technique [0002] Compared with other cleaning methods, ultrasonic cleaning has shown great advantages. Especially in specialized and group production enterprises, ultrasonic cleaning machines have gradually replaced traditional immersion cleaning, brush cleaning, pressure washing, vibration cleaning and steam cleaning. The high efficiency and high cleanliness of ultrasonic cleaning benefit from the penetration and cavitation shock waves generated when the sound waves propagate in the medium. Therefore, it is easy to clean parts with complex shapes, inner cavities and fine holes. For general degreasing, rust prevention, phosphating and other processes, it only takes two or three minutes to complete under the action of ultrasonic waves. Compared with the traditional method, it can be improved several times to dozens of times, and the cleanl...

AI Technical Summary

Problems solved by technology

[0004] It is pointed out in the rules of use of the ultrasonic generator that before turning on the ultrasonic generator, it must be ensured that there is water with a depth of at least 10cm in the cleaning tank, but since there is no protective device, its operation is completely guaranteed by the operator's care and operating habits. The process is correct; therefore, operating errors often occur, thereby increasing and reducing the maintenance cost and service life of the ultrasonic generator
