Abstract
The utility model relates to an ultrasonic transducer which comprises a shell, a vibration piece, a mounting seat, a ceramic crystal and a transmission line. A connecting portion of the transmission line and the mounting seat is sealed by the aid of a rubber ring, and an opening is formed in the bottom of the shell and sealed by the aid of a rubber ring. The ultrasonic transducer has the advantages that the ultrasonic transducer is waterproof, dustproof, simple in structure and easy to implement.
Description
Technical field
The utility model relates to a kind of equipment that utilizes piezo-electric effect work, particularly relates to a kind of ultrasonic transducer.
Background technology
Thereby ultrasonic transducer is to utilize ceramic piezo-electric effect that the mechanical oscillation of ultrasonic wave generation are changed into the signal of telecommunication or under electric field driven, produce mechanical oscillation to send hyperacoustic device.Because the transducing characteristic that it is good, is widely used in ultrasound examination field.Conventional ultrasonic transducer comprises housing, be placed in ceramic crystal in housing, be close to the vibrating reed that the ultrasonic wave receiving is amplified of being used for of ceramic crystal.Its structure as shown in Figure 1, Figure 2 shown in, in cylindrical housings, comprise mount pad, placing ceramic crystal on mount pad, housing top is sealed by the vibrating reed of being close to ceramic crystal.The lower housing portion of this ultrasonic transducer does not seal, if be 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 work of ultrasonic transducer.
Utility model content
The technical problem that the utility model solves is to provide a kind of ultrasonic transducer of simple in structure, good seal performance.
A kind of ultrasonic transducer, comprises 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 flying saucer shape, and placing ceramic crystal on the mount pad in described upper space, places 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 utility model utilizes mount pad and encapsulant that ceramic crystal is sealed in housing, has avoided water and dust to enter the possibility that affects ultrasonic transducer work in housing, makes the sealing property of ultrasonic transducer better.Simple in structure, be easy to carry out.
Accompanying drawing explanation
Fig. 1 is the structural representation of ultrasonic transducer of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the upward view of Fig. 1.
The specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, ultrasonic transducer of the present utility model 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.
In the bottom of lower space, be provided with opening 7, transmission line 9 enters lower space by opening 7, and access mount pad 2.At opening 7 places, with rubber ring 8, seal.At transmission line 9 with the link position of mount pad 2 with also using rubber ring 8 to seal.
Ultrasonic transducer of the present utility model, when transmitting excusing from death ripple, is connected transmission line 9 and electrical signal line on pottery
There are mechanical oscillation in crystal 3, after the ultrasonic wave that this mechanical oscillation form is amplified by vibrating reed 4, outwards launches.This
The ultrasonic transducer of utility model is when receiving ultrasonic wave, and ceramic crystal 3 receives the ultrasonic wave being amplified by vibrating reed 4, by it
Mechanical oscillation are exported by transmission line 9 after being converted into the signal of telecommunication.
