An ellipsoid portable ultrasonic transducer

Abstract

The invention discloses an ellipsoid-shaped portable ultrasonic transducer, which mainly includes an ellipsoid-shaped radiation head, etc., a front cover plate, a piezoelectric ceramic sheet, an electrode sheet, a back cover, and a back cover nut through a screw mechanically connected in series to form a transducer. The vibrator, the vibrator of the transducer is connected with the ellipsoidal radiation head through the protruding part of the screw to form the whole transducer. The sealing support connection, the connection between the ellipsoid shell and the watertight plug ensures its overall watertight characteristics, and the transducer as a whole is in contact with the water and radiates sound energy to it. The radiation head of the present invention uses an ellipsoid instead of a common cylinder or a circular table, and uses an ellipsoid as a whole to radiate instead of a plane or a cylinder, which can significantly increase the radiation surface of the transducer and improve the ability of the transducer to apply electric power; Into the water, which greatly reduces the noise radiated by the transducer through the water tank; it has the characteristics of cavitation corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of ultrasonic transducers, in particular to an ellipsoidal portable ultrasonic transducer. Background technique [0002] The longitudinal vibration type ultrasonic cleaning transducer widely used at present has the remarkable characteristics of simple structure, low cost, stable and reliable performance, etc. Ordinary transducers and other embedded transducers need to be attached to a carrier such as a vibrating box before they can be put into the water, which has the disadvantage of being unfavorable for the overall movement and portability of the device. [0003] In order to solve the shortcomings of the transducer, such as weak ability to apply electric power and inconvenient portability, domestic and foreign transducer experts have invented methods such as push-pull transducers by increasing the number of ceramic pieces, increasing the length of the tool head, and increasing the contact area with water. ...

AI Technical Summary

Problems solved by technology

Ordinary transducers and other embedded transducers need to be attached to a carrier such as a vibrating box before they can be put into the water, which is not conducive to the overall movement and portability of the device

[0003] In order to solve the shortcomings of the transducer, such as weak ability to apply electric power and inconvenient portability, domestic and foreign transducer experts have invented methods such as push-pull transducers by increasing the number of ceramic pieces, increasing the length of the tool head, and increasing the contact area with water. Transducers, etc., but these transducers need to be installed from top to bottom, which has obvious disadvantages such as loud noise and large space occupation, which is not conducive to home use or business people to carry

[0004] Whether it is an ultrasonic vibrating box composed of multiple vibrators, or an ultrasonic wand with a push-pull tool head, for household applications, there are significant shortcomings such as high noise, large volume, and not compact and beautiful appearance.

Embedded transducers have the disadvantage of being inconvenient to move and carry

[0005] In order to solve the problem of transducer immersion in water, some products at home and abroad put ordinary longitudinal vibration transducers into water as appropriate watertight, but there are problems such as small active radiation surface, weak ability to apply electric power, no corrosion resistance, and simple appearance.
