The invention provides an ultrasonic transducer, aiming at avoiding electrification of a cover body, namely avoiding electric leakage of the cover body part, so that the ultrasonic transducer can adapt to various liquid application occasions, such as washing occasions, operation occasions, welding occasions and the like, reduce the potential safety hazard of the ultrasonic transducer and improve user experience.
Specifically, as shown in fig. 1, the ultrasonic transducer of the present invention includes a cover 1, a first piezoelectric ceramic 2, a second piezoelectric ceramic 3, a positive electrode plate 4, a first negative electrode plate 5, a second negative electrode plate 6, a ground electrode plate 7, an ultrasonic vibration head 8, a first alumina ceramic 9 and a second alumina ceramic 10, where the cover 1, the first alumina ceramic 9, the first negative electrode plate 5, the first piezoelectric ceramic 2, the positive electrode plate 4, the second piezoelectric ceramic 3, the second negative electrode plate 6, the second alumina ceramic 10, the ground electrode plate 7 and the ultrasonic vibration head 8 are connected in sequence, and an outer contour of the first alumina ceramic 9 is larger than an outer contour of the first piezoelectric ceramic 2. An electromagnetic field is formed between the positive electrode plate 4 and the first negative electrode plate 5, an electromagnetic field is also formed between the positive electrode plate 4 and the second negative electrode plate 6, and mechanical vibration is generated by utilizing the piezoelectric effect of the first piezoelectric ceramic 2 and the second piezoelectric ceramic 3, so that the ultrasonic vibration head 8 vibrates. The first alumina ceramics 9 can prevent voltage breakdown to charge the cap body 1, and the second alumina ceramics 10 can prevent voltage breakdown to charge the ultrasonic vibration head 8, and at the same time, the ground electrode provides a more powerful guarantee that even if there is charge moving to the ultrasonic vibration head 8, it will be absorbed by the ground electrode. The fact that the outer contour of the first alumina ceramic 9 is larger than the outer contour of the first piezoelectric ceramic 2 means that along the connection direction of the components, a part of the first alumina ceramic 9 extends outwards relative to the first piezoelectric ceramic 2, i.e. if the first piezoelectric ceramic 2 projects towards the first alumina ceramic 9, the projected part is entirely within the first alumina ceramic 9, which is advantageous in that the electric charge of the electromagnetic field does not bypass the first alumina ceramic 9 to charge the cover body 1, thereby ensuring that the cover body 1 is not charged and the leakage situation occurs. In practical applications, the first piezoelectric ceramic 2 may be in a disk shape, or may be in other shapes, and the first alumina ceramic 9 may be in a disk shape, of course, the first alumina ceramic 9 may also be in a square block shape, or other cases, and a person skilled in the art may flexibly set the shapes of the first piezoelectric ceramic 2 and the first alumina ceramic 9 in practical applications as long as the outer contour of the first alumina ceramic 9 is ensured to be larger than the outer contour of the first piezoelectric ceramic 2.

Similarly to the foregoing, the fact that the outer contour of the second aluminum oxide ceramic 10 is larger than the outer contour of the second piezoelectric ceramic 3 means that along the connection direction of the components, a part of the second aluminum oxide ceramic 10 extends outward relative to the second piezoelectric ceramic 3, that is, if the second piezoelectric ceramic 3 projects toward the second aluminum oxide ceramic 10, the projected part is entirely within the second aluminum oxide ceramic 10, which has the advantage that the electric charge of the electromagnetic field does not cross and bypass the second aluminum oxide ceramic 10 to electrify the ultrasonic vibration head 8, thereby ensuring that the ultrasonic vibration head 8 is not electrified, and through the combination of the second aluminum oxide ceramic 10 and the grounding electrode, it can be ensured that the ultrasonic vibration head 8 is not electrified all the time, even if the ultrasonic vibration head 8 is extended into the environment with liquid, the electric shock condition can not occur, and the safety risk is greatly reduced. In practical application, the second piezoelectric ceramic 3 may be disc-shaped, or may be in other shapes, and the second alumina ceramic 10 may be disc-shaped, and certainly, the second alumina ceramic 10 may also be in a square block shape or other situations, and a person skilled in the art may flexibly set the shapes of the second piezoelectric ceramic 3 and the second alumina ceramic 10 in practical application as long as it is ensured that the outer contour of the second alumina ceramic 10 is larger than the outer contour of the second piezoelectric ceramic 3.

The water containing component 200 and the mounting component 300 can slide relative to the shell, the mounting component 300 can drive the ultrasonic transducer 100 to slide relative to the shell in the process of sliding relative to the shell, the ultrasonic transducer 100 can emit ultrasonic waves into the water containing component 200, specifically, the ultrasonic vibration head emits the ultrasonic waves into the water containing component 200, and a user can put articles into the water containing component 200 for ultrasonic washing. In the above, the water containing member 200 may be a water containing tank, a water containing tray, a water containing box, or the like, and the mounting member 300 may be a mounting bracket, a mounting plate, a mounting seat, or the like.
