Technical field

The present invention relates to oral health technical fields, more particularly to a kind of sound vibration toothbrush.

Background technique

Electric toothbrush currently on the market is all using direct current generator as vibration source, in addition eccentric wheel reaches increase vibration The effect of amplitude, as a result, entire toothbrush includes that handle portion is all vibrating, poor user experience while cost of manufacture is high, vibration Dynamic rail mark is indefinite, and often in vibration processes, product structure itself absorbs a part of amplitude, and vibrating effect is poor, cleaning effect It is unobvious, it is based on disadvantages described above and deficiency, it is necessary to be improved the prior art, design a kind of sound vibration toothbrush.

Summary of the invention

The invention mainly solves the technical problem of providing a kind of sound vibration toothbrushs, and structure is simple, at low cost, with direct current Motor is higher compared to frequency, has the effect that preferably cleans one's teeth, and hand-held part generates micron-sized vibration, and human body is difficult to feel, improves User experience.

In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of sound vibration toothbrush is provided, it should Kind sound vibration toothbrush includes handle, brush handle, brush head and sound wave vibration generating arrangement, and the brush head connects handle by brush handle, The handle is built-in with acoustic vibration generating device, the acoustic vibration generating device include acoustic wave transducer, drive module and Battery module, acoustic wave transducer, which is located at, is embedded in handle and brush handle junction, and drive module and battery module are located in handle, described Drive module connects acoustic wave transducer and battery module by signal.

Preferably, the acoustic wave transducer includes metal framework and piezoelectric ceramics, and metal framework is close to one end of handle Rectangular, rectangular-shaped place is closely embedded with piezoelectric ceramics, and piezoelectric ceramics generates vibration, metal framework under the driving of alternating current One end close to brush head is in long strip, and piezoelectric ceramic vibration drives strip portion to vibrate up and down, so that brushhead vibration is driven, strip Shape extension end, which is vibrated up and down, amplifies amplitude by lever principle, works at the resonant frequency fx, and frequency is between 300~800Hz, pottery Porcelain position generates micron-sized vibration.

Preferably, the metal framework uses metal alloy or engineering plastics, including aluminium alloy and stainless steel.

Preferably, the piezoceramic material is PZT base, barium titanate or potassium niobate sodium-based leadless piezoelectric ceramic, piezoelectricity Ceramics are using epoxy glue bonding block or monolithic structure.

Preferably, the battery module exports alternating current, and battery module output voltage is ± 3.0V~± 30V.

Preferably, this kind of sound vibration toothbrush further includes holding rubber sleeve, holds rubber sleeve and is set on handle.

Compared with prior art, at low cost the beneficial effects of the present invention are: structure is simple, the frequency compared with direct current generator It is higher, there is the effect that preferably cleans one's teeth, hand-held part generates micron-sized vibration, and human body is difficult to feel, improves user experience.
