Third: the invention patent of application number 91101403.9 and the tooth cleaning mobile phone in the current domestic products are integrated with the outer cable. This structure cannot be sterilized by high temperature and high pressure (saturated steam)
Once the seal of the O-shaped rubber ring leaks under high temperature and high pressure environment, it is not easy to maintain the dental cleaning handpiece
In addition, judging from the current configuration of a tooth cleaning machine and a tooth cleaning mobile phone, it is obviously difficult to achieve high temperature and high pressure disinfection for one person at a time, and the configuration of more than one tooth cleaning mobile phone is expensive

Embodiment Construction
[0007] Embodiments of the present invention are described below in conjunction with accompanying drawings, wherein the transducer machine of the present invention is constituted by horn 8, four piezoelectric ceramics 6, insulating sleeve 5, horn sleeve 9, wire 12 and five pole pieces 7. core. Put the insulating sleeve 5 on the elastic rod 19 of the horn 8, and heat shrink it tightly, put the pole piece 7 and the piezoelectric ceramic 6 into the boss 20 of the horn in turn, screw the horn sleeve 9, Press the pole piece and the piezoelectric ceramic between the boss 20 of the horn and the end face of the horn sleeve 9, connect the pole piece with the lead wire to connect the piezoelectric ceramic into a parallel form, and lead out the lead wire 12, adjust the horn 8 and the tightness of the luffing sleeve 9, in order to obtain a suitable prestress parameter and resonance frequency, set the O-ring 10 on the rear of the luffing sleeve 9, and put the assembled core into the transdu...

The safe long-life ultrasonic dental cleaner hand drill for removing dental calculus, smoking patch and dental plaque is characterized by adopting a new structure, its transducer can be arbitrary dismounted from said dental cleaner hand drill or mounted on it, its external exposed component can be disinfected at high temp. and high pressure, its amplitude-changing lever is a tubular body whose middle is perforated, and its middle portion possesses an elastic bar and screw-thread part for connecting amplitude-changing sleeve, the outside diameter of the elastic bar is less than inside diameter of thread of screw-thread part, and the elastic bar has an enough length so as to make the ratio of its amplitude and the length of elastic bar be less than 1%. The service life is greatly raised, it can implement one man once high-temp. high-pressure disinfection, and can prevent cross infection.
Description
technical field [0001] The invention relates to an ultrasonic tooth cleaning device, in particular to an ultrasonic tooth cleaning mobile phone. Background technique [0002] Relying on mechanical vibration to generate ultrasonic waves to remove tartar, soot and bacteria is a very popular method for dental cleaning. Among them, the mobile phone with piezoelectric ceramics as the vibration source is the simplest and occupies a dominant position in the mobile phone. At present, in addition to the products of several domestic companies, there are also many products imported from France, the United States and Switzerland in the market. Users generally reflect that the service life of domestic mobile phones is too short and the temperature of mobile phones rises. More typical in the prior art has application number to be 91101403.9, the name is called the Chinese invention patent of " ultrasonic dental scaler ". This invention patent discloses an ultrasonic ...
