The beneficial effects of the invention are as follows:
the invention provides an ultrasonic treatment effect detection device which comprises a detection plate, a detection part and a restoration plate. Wherein, the pick-up plate adopts the platy structure, and the middle part of pick-up plate is provided with the recess. The detection part is embedded in a groove arranged on the detection plate and is made of a memory material. The restoring plate is connected to one end of the detecting plate through a hinge, and when the restoring plate is folded with the detecting plate, the restoring part on the restoring plate is in close contact fit with the detecting part, so that the detecting part restores the original flat appearance. When the ultrasonic effect detection is carried out, the ultrasonic treatment effect detection device is placed at a position to be detected (for example, when ultrasonic cleaning is carried out, the ultrasonic treatment effect detection device is placed in cleaned water), cavitation is caused by ultrasonic waves (a large amount of small bubbles can be generated when the ultrasonic waves act on liquid), one reason is that the liquid locally generates tensile stress to form negative pressure, gas originally dissolved in the liquid is supersaturated and escapes from the liquid to form the small bubbles, and the other reason is that the strong tensile stress "tears" the liquid into a cavity, namely, cavitation, liquid vapor or another gas dissolved in the liquid, and even vacuum, the small bubbles formed by the cavitation continuously move, grow or suddenly break along with the vibration of surrounding media, and the surrounding liquid suddenly rushes into the bubbles to generate high temperature and high pressure during the break, and shock waves are generated at the same time. Therefore, a plurality of pits formed by cavitation are generated on the surface of a detection part (the detection part is made of a memory material which is not automatically restored after being stressed by a tin sheet or a memory sponge) with memory by ultrasonic waves, and then after the detection of the ultrasonic treatment effect detection device is completed, the detection device is taken out, and the effect of ultrasonic treatment can be intuitively judged by observing the size of the pits on the surface of the detection device. After the detection is finished once, the detection plate and the recovery plate are folded, so that the recovery part on the recovery plate is pressed on the detection part, and under the flattening effect of the recovery part, the pits on the surface of the original detection part are flattened, so that the detection part can continue to carry out the next measurement without being influenced by the last detection result. In summary, the ultrasonic treatment effect detection device disclosed by the invention has the function of intuitively detecting the ultrasonic treatment effect, so that a worker can timely find the problems of ultrasonic equipment and adjust, maintain or replace the ultrasonic equipment, and the quality of products is ensured. And the ultrasonic treatment effect detection can be continuously and repeatedly performed.
By arranging the magnetic attraction parts on the detection plate and the recovery plate, when the detection plate and the recovery plate are folded, the detection part can be restored to the original flat shape only by giving smaller force. The force for recovering the original shape of the detection part is saved.
Through setting up the recess into the structure that reduces gradually from bottom to top area for the firm card of detection portion is in the recess, when carrying out ultrasonic detection, can not make detection portion drop from the recess inside because of the influence of ultrasonic wave.
