Environment-friendly noise-reducing ultrasonic cleaning device

Abstract

The invention discloses an environment-friendly noise-reducing ultrasonic cleaning device. The ultrasonic cleaning device comprises a mounting box, wherein the top face of the mounting box is connected with a sound insulation part through a first connecting mechanism, the first connecting mechanism is arranged at the joint of the sound insulation part and the mounting box, a mounting groove is dug in the middle of the top face of the mounting box, an inner cavity of the mounting groove is connected with a protective mechanism through a second connecting mechanism, an ultrasonic cleaner body is arranged in an inner cavity of the protective mechanism, the sound insulation plate is arranged on the top face of the mounting box through a first connecting mechanism, the sound insulation plate is filled with a sound absorption sponge layer, a protective frame is arranged in the inner cavity of the mounting groove through a second connecting mechanism, a containing groove is dug in the top face of the protective frame, a noise-reducing sponge block is arranged in an inner cavity of the containing groove, and a groove is dug in the middle of the top face of the protective frame. The ultrasonic cleaning device is simple in structure and convenient to mount and dismount, noise generated by an ultrasonic body is well adsorbed, and the hearing comfort of a user is improved.

Description

technical field [0001] The invention relates to an environment-friendly and noise-reducing ultrasonic cleaning device, which belongs to the technical field of ultrasonic cleaning. Background technique [0002] With the development of science and technology and the progress of society, there are various cleaning tools and methods. At the same time, the ultrasonic cleaning method is effective and easy to operate. For the principle of ultrasonic cleaning machine, the high-frequency oscillation signal sent by the ultrasonic generator passes through the transducer. It is converted into high-frequency mechanical vibration and propagated to the medium—cleaning solvent.

[0002] With the development of science and technology and the progress of society, there are various cleaning tools and methods. At the same time, the ultrasonic cleaning method is effective and easy to operate. For the principle of ultrasonic cleaning machine, the high-frequency oscillation signal sent by the ultrasonic generator passes through the transducer. Converted into high-frequency mechanical vibration and propagated to the medium——cleaning solvent, the ultrasonic wave radiates forward in the cleaning liquid, making the liquid flow and generating tens of thousands of tiny bubbles with a diameter of 50-500 μm, which exist in the The tiny bubbles in the liquid vibrate under the action of the sound field. These bubbles form and grow in the negative pressure zone where the ultrasonic wave propagates longitudinally. In the positive pressure zone, when the sound pressure reaches a certain value, the bubbles increase rapidly, then suddenly close, and Shock waves are generated when the bubbles are closed, and thousands of atmospheric pressures are generated around them, destroying insoluble dirt and making them disperse in the cleaning liquid. When the group particles are wrapped in oil and adhere to the surface of the cleaning parts, the oil is emulsified, and the solid particles And detachment, so as to achieve the purpose of purifying the cleaning parts. In this process called "cavitation" effect, the bubble closure can form a high temperature of several hundred degrees and an instantaneous high pressure of more than 1000 air pressure. In the prior art, due to Ultrasound generates vibration, which makes the box where the ultrasonic body is placed make noise, causing users to produce harsh sounds in the hearing
