Abstract
The utility model discloses a piezoelectric transducer for an ultrasound skin beautifying apparatus and relates to the technical filed of electronic elements. The piezoelectric transducer for the ultrasound skin beautifying apparatus comprises a piezoelectric ceramic sheet, a metal sheet, two metal electrodes and electrode wires; the metal electrode on the front surface of the piezoelectric ceramic sheet is composed of a silver layer sintered on the piezoelectric ceramic sheet; the metal electrode on the back surface of the piezoelectric ceramic sheet is composed of a silver layer sintered on the piezoelectric ceramic sheet and a metal sheet stuck on the metal layer through conductive glue; the electrode wires are respectively welded on the metal electrodes; a lug extends from the edge of the metal sheet; the electrode wire of the metal electrode on the back surface of the piezoelectric ceramic sheet is welded on the lug; and the piezoelectric ceramic sheet and the metal sheet are both in a perfect circle shape. The piezoelectric transducer for the ultrasound skin beautifying apparatus has the advantages that the piezoelectric transducer is firm and durable and is convenient to package and weld.
Description
Technical field
The utility model relates to technical field of electronic components, particularly relates to a kind of parts of ultrasonic skin makeup instrument apparatus.
Background technology
Ultrasonic skin makeup instrument probe outside is inlaid with bristle, and the frequency that produces through ultrasonic vibration realizes, reach the clean to skin of face, and the PZT (piezoelectric transducer) that is installed in the probe is the parts that are used for producing ultrasonic vibration.Its structure is a slice piezoelectric ceramic piece, and its both sides sintering one deck silvery thin layer respectively directly are connected in the circuit behind the welding lead as positive and negative electrode.Owing to be the welding electrode lead on the two sides of piezoelectric ceramic piece, lead-in wire connects inconvenient, and welding back gross thickness is bigger, be unfavorable for encapsulation and fixing of energy converter, and piezoelectric ceramic piece ruptures easily.
Summary of the invention
The purpose of the utility model is to overcome the existing defective that the firm degree of PZT (piezoelectric transducer) is relatively poor, lead packages is inconvenient, and a kind of improved PZT (piezoelectric transducer) is provided.
It comprises piezoelectric ceramic piece, sheet metal, two metal electrodes and electrode cable the utility model; Said two metal electrodes place respectively piezoelectric ceramic piece just, the back of the body two sides on; The positive metal electrode of piezoelectric ceramic piece is made up of the silver layer of sintering on piezoelectric ceramic piece; The metal electrode at the piezoelectric ceramic piece back side is made up of at silver layer on the piezoelectric ceramic piece and the sheet metal that sticks on the silver layer through conducting resinl sintering; Electrode cable is welded on respectively on the metal electrode, and said sheet metal edge is extended with a lug, and the electrode cable of piezoelectric ceramic piece back metal electrode is welded on the lug; Electrode cable is straight weldering property enamel-covered wire, and handle through tin sticky at its two; Said piezoelectric ceramic piece and sheet metal are positive circle.
The beneficial effect of the utility model is: the whole employing of PZT (piezoelectric transducer) is just round, and consistent with the skin makeup probe, an electrode of PZT (piezoelectric transducer) is a sheet metal; Electrode cable is welded on the lug of sheet metal, and the electrode bond strength improves greatly, and piezoelectric ceramic piece is in the same place through the conducting resinl glue bond with sheet metal; The fastness and the intensity of transducer have been improved; Electrode pads has reduced thickness in same direction, is convenient to encapsulation.
Description of drawings
Fig. 1 is the vertical profile sketch map of the ultrasonic skin makeup appearance of the utility model with PZT (piezoelectric transducer);
Fig. 2 is the vertical view of ultrasonic skin makeup appearance shown in Figure 1 with PZT (piezoelectric transducer).
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
Like Fig. 1, shown in Figure 2, among the figure: 1, sheet metal, 2, lug, 3, electrode cable, 4, silver layer, 5, piezoelectric ceramic piece, 6, silver layer, 7, electrode cable.
It comprises piezoelectric ceramic piece, sheet metal, two metal electrodes and electrode cable; Two metal electrodes place respectively piezoelectric ceramic piece just, the back of the body two sides on; The positive metal electrode of piezoelectric ceramic piece is made up of the silver layer of sintering on piezoelectric ceramic piece; The metal electrode at the piezoelectric ceramic piece back side is made up of at silver layer on the piezoelectric ceramic piece and the sheet metal that sticks on the silver layer through conducting resinl sintering; Electrode cable is welded on respectively on the metal electrode, and the sheet metal edge is extended with a lug, and the electrode cable of piezoelectric ceramic piece back metal electrode is welded on the lug; Electrode cable is straight weldering property enamel-covered wire, and handle through tin sticky at its two; Piezoelectric ceramic piece and sheet metal are positive circle.
During use PZT (piezoelectric transducer) is contained in the cavity of skin makeup appearance head, transducer two sides and cavity are combined closely, and electrode cable is connected on the ultrasonic circuit.
