Description
Technical field
This utility model relates to the applications of ultrasound technical field, especially a kind of interchangeability ultrasonic transduction output block circuit.
Background technology
At the ultrasonic therapeutic technology, owing to need ultrasonic accurately output, but because being connected of the parameter difference opposite sex that causes of piezoelectric transducer manufacturing process and piezoelectric transducer and other device, the bonding parameters of operating part diversity that causes, make under same incentive condition, to obtain identical ultrasonic output or one permissible variation scope accurately.Traditional method is to come the permissible variation scope accurately with the identical ultrasonic output of the acquisition that obtains or according to the driving voltage that different ultrasonic transduction parts are adjusted drive circuits.Circuit debugging is complicated and increase circuit cost like this, does not satisfy the interchangeability of parts, is not suitable for batch production requirements.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of interchangeability ultrasonic transduction output block circuit is provided.
A kind of interchangeability ultrasonic transduction output block circuit comprises controllable impedance, piezoelectric transducer, and controllable impedance and piezoelectric transducer are composed in series interchangeability ultrasonic transduction output block circuit.
The interchangeability ultrasonic transduction output block circuit that described controllable impedance and piezoelectric transducer are composed in series is connected in the driving exciting circuit.
Described controllable impedance is a HF-01 type controllable impedance, and inductance range is 12～16uH.
The specification of described piezoelectric transducer device is P-8 material, φ 30mm, 1MHz.
Interchangeability ultrasonic transduction output block circuit can be used for the treatment head member of sonicator.
The beneficial effects of the utility model are:
Interchangeability ultrasonic transduction output block circuit of the present utility model, the precision height makes ultrasonic output that under same incentive condition acquisition is identical or one permissible variation scope accurately.With simplification testing and measuring technology and saving cost, and the replacing problem of solution after-sale service parts.
Description of drawings
Fig. 1 is an interchangeability ultrasonic transduction output block circuit diagram of the present utility model.
Fig. 2 is the equivalent circuit diagram of ultrasonic transducer.
Fig. 3 is an interchangeability ultrasonic transduction output block work wave sketch map.
The specific embodiment
Fig. 1 is an interchangeability ultrasonic transduction output block circuit diagram of the present utility model.
Fig. 2 is the equivalent circuit diagram of ultrasonic transducer.
When equivalent capacity 4 resonance of controllable impedance 1 and equivalent circuit during in the excitation operating frequency, its excitation voltage waveform and current waveform respectively shown among Fig. 36 and 7, driving voltage and electric current homophase, circuit efficiency is the highest.The little perceptual off resonance of forming when controllable impedance 1 and equivalent capacity 4 of circuit is during in the excitation operating frequency, its voltage waveform and current waveform are respectively shown among Fig. 36 and 8, the little excitation voltage waveform that lags behind of current waveform, circuit efficiency also realizes treating the change of an output with regard to being implemented under the identical excitation by changing inductance value with top described different.According to this principle, same type piezoelectric transducer is owing to being connected of the parameter difference opposite sex that causes of manufacturing process and piezoelectric transducer and other device, the bonding parameters of operating part diversity that causes can make each ultrasonic transduction output block export identical power under identical incentive condition by adjusting its series inductance.The 5th, the damping resistance of equivalence.
Described controllable impedance is a HF-01 type controllable impedance, and inductance range is 12～16uH.
The specification of described piezoelectric transducer device is P-8 material, φ 30mm, 1MHz.
10 EMP-5000 sonicator complete machines that our company produces are according to said method debugged with the treatment head member, exchange test through complete machine and treatment head member, when 20W shelves output, deviation range is in ± 0.5W, realize intended purposes, also verify effectiveness of the present utility model.
More than describing only is concrete application example of the present utility model, be not in order to limit the application range of this patent, under the spirit that does not break away from this patent announcement, present embodiment is changed, but these changes are interpreted as being included in the scope of present patent application.
