A Portable Multipurpose Ultrasonic Transducer Based on Ellipsoid Shell

Abstract

The invention discloses a portable multi-purpose ultrasonic transducer based on an ellipsoidal shell, which mainly includes an ellipsoidal radiation head, etc., a front cover, a piezoelectric ceramic sheet, an electrode sheet, a back cover, and a back cover nut. The upper part is connected in series to form a transducer vibrator. The transducer vibrator is connected with the ellipsoidal radiation head through the protruding part of the screw to form the whole transducer. The whole transducer is connected with the stepped slender tool head to form an ultrasonic transducer. The device is placed in the ellipsoid shell and the two are sealed and supported through the sealing ring and the thread on the ellipsoidal radiation head. The bottom of the ellipsoid shell is connected with the watertight plug to ensure its overall watertight characteristics. The invention improves the ability of the transducer to apply electric power; greatly reduces the noise radiated by the transducer through the water tank; makes the transducer both portable and aesthetically pleasing; has cavitation corrosion resistance; collects partial cleaning of clothes and cleaning of the water tank , small diameter cup cleaning and other purposes in one.

Description

technical field [0001] The invention relates to the field of ultrasonic transducer technology, in particular to a portable multipurpose ultrasonic transducer based on an ellipsoidal shell. 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 sealed box before they can be put into 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 co...

AI Technical Summary

Problems solved by technology

Ordinary transducers and other embedded transducers need to be attached to a carrier such as a sealed 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 addition, 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 they have small active radiation surface, weak ability to apply electric power, no corrosion resistance, and simple appearance, etc. question

[0006] More, the ellipsoidal portable ultrasonic transducer without a stepped tool head has the disadvantage of a relatively single use method, which limits the overall value of the transducer
