Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, an ultrasonic cleaning device comprises a cleaning tank body 1 and an ultrasonic generator 2, wherein an inclined plane 3 is arranged at one side of the bottom of the cleaning tank body 1, the ultrasonic generator 2 is arranged at a position corresponding to the inclined plane 3, a water inlet valve 7 is arranged above the inclined plane 3, at least two control chambers 5 are arranged at the other side corresponding to the cleaning tank body 1, each control chamber 5 is provided with a control valve 6, a control inclined plate 4 is arranged between the control chamber 5 and the cleaning tank body 1, uniform through holes are arranged on the control inclined plate 4, the flow rate of the control chamber 5 is controlled through the control valve 6, and then the passing speed of water at different heights of the control inclined plate 4 is controlled, so that the flow rate of water in the cleaning tank body 1 is different at different heights, the control inclined plate 4 is also inclined due to the inclination of the ultrasonic direction, the ultrasonic is reflected to other directions, the influence of standing waves is reduced.

The angle between the inclined plane 3 and the horizontal plane is less than forty-five degrees, the angle between the bottom of the control inclined plate 4 and the horizontal plane is greater than forty-five degrees, and the extension section of the control inclined plate 4 and the extension line of the side wall of the cleaning tank body 1 are in intersection, so that the ultrasonic reflection direction is deviated to the right side, and the interference on cleaning workpieces is small.
