Thus, in a further embodiment of the present invention, as shown in fig. 2 and 7, the input terminal assembly 50 may further include: a first blocking piece 53, a first restoring piece 54, a second blocking piece 55 and a second restoring piece 56.

As shown in fig. 2 and 7, the first blocking piece 53 is movably disposed in the first slot 511, and when the output terminal part 60 is inserted into the input terminal part 50, the first blocking piece 53 can be moved inward by the pushing of the output terminal part 60, so that the slot of the first slot 511 is opened, and the output terminal part 60 can be inserted into the first slot 511. As shown in fig. 7 and 8, when the output terminal part 60 is separated from the input terminal part 50, the first reset part 54 may push the first blocking part 53 to be reset to the initial position, so that the first blocking part 53 may block the notch of the first slot 511. That is, the first reset piece 54 can drive the first blocking piece 53 to be always located at a position for blocking the notch of the first slot 511, so as to prevent a user from getting electric shock when the user extends into the first slot 511 from the notch of the first slot 511, and can automatically block the notch of the first slot 511 after the input terminal part 50 is separated from the output terminal part 60, thereby being free from manual operation and being more convenient to use.

With continued reference to fig. 2 and 7, the second blocking piece 55 is movably disposed in the second slot 512, and when the output end member 60 is inserted into the input end member 50, the second blocking piece 55 can be pushed by the output end member 60 to move inward, so that the slot of the second slot 512 is opened, and the output end member 60 can be inserted into the second slot 512. As shown in fig. 7 and 8, when the output terminal member 60 is separated from the input terminal member 50, the second restoring member 56 may push the second blocking member 55 to be restored to the initial position, so that the second blocking member 55 may block the notch of the second insertion groove 512. That is to say, the second reset piece 56 can drive the second blocking piece 55 to be located at a position for blocking the notch of the second slot 512, so as to prevent the user from getting electric shock by the second slot 512 extending into the second slot 512, and can automatically block the notch of the second slot 512 after the input terminal component 50 is separated from the output terminal component 60, without manual operation, thereby being more convenient for use.

It should be noted that, in the present invention, the input terminal component 50 may include the first blocking element 53, the first resetting element 54, the second blocking element 55 and the second resetting element 56 at the same time, or may include only the first blocking element 53 and the first resetting element 54, or only the second blocking element 55 and the second resetting element 56, which may all reduce the risk of electric shock.

In some embodiments of the present invention, as shown in fig. 2 and 7, the upper portion of the first blocking piece 53 may be provided with a first fitting groove 531, the first restoring piece 54 may be a coil spring, the coil spring may be externally sleeved on the first blocking piece 53, and the coil spring may be stopped against the first fitting groove 531 and the bottom wall surface of the first slot 511. When the output terminal part 60 is inserted into the input terminal part 50, the output terminal part 60 pushes the first blocking part 53, so that the first resetting part 54 is compressed, and when the output terminal part 60 is separated from the input terminal part 50, the restoring force of the first resetting part 54 can restore the first blocking part 53. The first fitting groove 531 and the first slot 511 may restrict the position of the coil spring, preventing the first restoring member 54 from coming out of the first slot 511 and the first fitting groove 531 or from being excessively deformed to affect the driving action of the first blocking member 53.

As shown in fig. 2 and 7, the second blocking member 55 may be provided at an upper portion thereof with a second fitting groove 551, the second returning member 56 may be a coil spring, the coil spring may be externally fitted over the second blocking member 55, and the coil spring may be stopped against the second fitting groove 551 and the bottom wall surface of the second slot 512. When the output terminal part 60 is inserted into the input terminal part 50, the output terminal part 60 pushes the second blocking part 55, so that the second resetting part 56 is compressed, and when the output terminal part 60 is separated from the input terminal part 50, the restoring force of the second resetting part 56 can restore the second blocking part 55. The second fitting groove 551 and the second slot 512 can limit the position of the coil spring, and prevent the second restoring member 56 from being disengaged from the second fitting groove 551 and the second slot 512 or from being deformed too much to affect the driving action of the second blocking member 55.

When the positive electrode sheet 322 and the negative electrode sheet 323 are energized, the voltage across the two end faces of the piezoelectric sheet 321 can be changed, and the piezoelectric sheet 321 generates high-frequency vibration under current excitation by utilizing the inverse piezoelectric effect, so that conversion from electric power to mechanical power is realized, and ultrasonic waves are generated.

In the present invention, the number of the piezoelectric sheets 321, the positive sheets 322 and the negative sheets 323 can be adjusted according to the actual requirement, the arrangement positions of the positive sheets 322 and the negative sheets 323 include but are not limited to those shown in fig. 9, and the ultrasonic vibrator device 30 can output ultrasonic waves with different intensities to meet different use requirements.

As shown in fig. 9, the lower end block 33 may be provided at a lower portion in the axial direction of the piezoelectric module 32, the ultrasonic wave emitting unit 31 may be provided at an upper portion in the axial direction of the piezoelectric module 32, the fastener 34 may be inserted into the lower end block 33, the piezoelectric module 32, and the ultrasonic wave emitting unit 31 in this order to connect the lower end block 33, the piezoelectric module 32, and the ultrasonic wave emitting unit 31 together for pretension, and the ultrasonic wave transducer device 30 is formed as a sandwich type ultrasonic wave transducer device. The piezoelectric module 32 can be fixed by the lower end block 33 and the ultrasonic wave emitting unit 31 being engaged with each other, so that the stability of the piezoelectric module 32 can be improved, and the resonance frequency of the ultrasonic transducer device 30 can be adjusted to transmit energy. The sandwich type ultrasonic vibrator device is easy to process, easy to adjust the frequency and simple in structure.

In addition, as shown in fig. 9, the ultrasonic wave emitting unit 31 may have a metal ring wall 313 extending into the through hole of the piezoelectric element 32, and the metal ring wall 313 may limit the position of the piezoelectric element 32, so that the piezoelectric element 32 is fixed more firmly. The insulating sleeve 35 can be sleeved on the metal annular wall 313 to isolate the positive plate 322 and the negative plate 323 from metal, and the inner peripheral edge of the piezoelectric assembly 32 is insulated from the metal annular wall 313 to prevent the positive plate 322 and the negative plate 323 from being short-circuited, and meanwhile, the electric energy of the piezoelectric assembly 32 is prevented from being transmitted to the ultrasonic transmitting part 31 to cause electric shock of a user, so that the safety and the reliability are higher.
