Abstract

The invention relates to an ultrasonic transducer, which comprises a casing, a vibration piece, an installing seat, a ceramic crystal and a transmission wire, wherein the connecting parts of the transmission wire and the installing seat are sealed by a rubber ring, an opening is formed at the bottom of the casing, and the opening part is sealed by the rubber ring. The ultrasonic transducer provided by the invention has the advantage of waterproof and dustproof functions. In addition, the structure is simple, and the implementation is easy.

Description

Ultrasonic transducer
Technical field
The present invention relates to a kind of equipment that utilizes piezo-electric effect work, particularly relate to a kind of ultrasonic transducer.
Background technology
Thereby ultrasonic transducer is to utilize ceramic piezo-electric effect to change the mechanical oscillation of ultrasonic wave generation into the signal of telecommunication or produce mechanical oscillation under electric field driven to send hyperacoustic device.Because the transducing characteristic that it is good, be widely used in the ultrasound examination field.Ultrasonic transducer commonly used comprises housing, be placed in ceramic crystal in housing, be close to the vibrating reed that the ultrasonic wave that is used for receiving of ceramic crystal amplifies.Its structure as shown in Figure 1, Figure 2 shown in, comprise mount pad in cylindrical housings, placing ceramic crystal on mount pad, housing top is by the vibrating reed sealing of being close to ceramic crystal.The lower housing portion of this ultrasonic transducer is sealing not, if it is installed on ultrasonic flowmeter, in actual measurement, water enters in housing 1 from the bottom of housing 1 with regard to being easy to, thereby affects the normal operation of ultrasonic transducer.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of ultrasonic transducer of simple in structure, good seal performance.
A kind of ultrasonic transducer, comprise housing, mount pad, vibrating reed and ceramic crystal, and housing is divided into upper space, lower space, between described upper space and lower space, is provided with mount pad, and an opening is arranged at described lower space bottom.
Further, described housing becomes the flying saucer shape, and placing ceramic crystal on the mount pad in described upper space, place vibrating reed on described ceramic crystal, and transmission line is by the opening access mount pad of lower space.
Further, described opening part is used seal with elastometic washer.
Further, described transmission line and mount pad connecting portion are used anti-seal with elastometic washer.
Further, the thickness of described vibrating reed is 0.5 millimeter.
Further, described vibrating reed is shaped as truncated conical shape.
Ultrasonic transducer of the present invention utilizes mount pad and encapsulant that ceramic crystal is sealed in housing, has avoided water and dust to enter in housing the possibility that affects ultrasonic transducer work, makes the sealing property of ultrasonic transducer better.Simple in structure, be easy to carry out.
The accompanying drawing explanation
The structural representation that Fig. 1 is ultrasonic transducer of the present invention;
The top view that Fig. 2 is Fig. 1;
The upward view that Fig. 3 is Fig. 1.
The specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, ultrasonic transducer of the present invention comprises housing 1, ceramic crystal 3 and vibrating reed 4.Housing 1 comprises mount pad 2, upper space 5 and lower space 6, and lower space 6 has an opening 7.
In upper space 5, top of space is equipped with vibrating reed 4, and vibrating reed 4 is truncated conical shape, and thickness is 0.5 millimeter, and ceramic crystal 3 is placed on mount pad 2, and vibrating reed 4 is close at the top of ceramic crystal 3.
Be provided with opening 7 in the bottom of lower space, transmission line 9 enters lower space by opening 7, and access mount pad 2.At opening 7 places, with rubber ring 8, seal.At the link position of transmission line 9 and mount pad 2 with also using rubber ring 8 to seal.
Ultrasonic transducer of the present invention, when emission excusing from death ripple, is connected transmission line 9 and electrical signal line on pottery
Mechanical oscillation occur in crystal 3, and the ultrasonic wave that this mechanical oscillation form is outwards launched after being amplified by vibrating reed 4.This
The ultrasonic transducer of invention is when receiving ultrasonic wave, and ceramic crystal 3 receives the ultrasonic wave amplified by vibrating reed 4, by it
Mechanical oscillation are exported by transmission line 9 after being converted into the signal of telecommunication.
