Abstract
The present invention relates to an ultrasonic driving device with multifrequency scanning, which is applicable for driving a plurality of oscillators to vibrate by emitting ultrasonic, and including a signal generating module, an output module and an ultrasonic transduction module. The signal generating module generates and outputs an alternating first driving signal to the output module, and the frequency of the first driving signal is changed in a certain range. The output module adjusts the size of the first driving signal into a second driving signal, and outputs the second driving signal. The ultrasonic transduction module receives the second driving signal and emits ultrasonic wave which has the same frequency range with the second driving signal so as to drive the oscillators to vibrate. As the frequency of the first driving signal is changed in a certain range, the oscillators with different frequency are able to be driven to vibrate.
Description
Technical field
The present invention relates to a kind of drive unit, particularly relate to a kind of ultrasonic driving apparatus of tool multi-frequency scanning.
Background technology
Ultrasonic wave (ultra-sonic) is meant that frequency is more than 20KHz and the sound wave that can't sense of human ear.Ultrasonic wave has the purposes of many aspects, and for example supersonic wave cleaning machine is that ultrasonic wave is imported in the cleaning fluid, and makes cleaning fluid produce disturbance by ultrasonic wave, cleans the effect that is immersed in the thing to be cleaned in the cleaning fluid to reach.Even the ultrasonic hyperthermia machine that is applied to medical aspect is also arranged, the ultrasonic wave that is produced by heat therapy machine is sent to the depth layer of muscle and produces heat energy through skin, and then reaches the effect of rehabilitation thermotherapy.
Consult Fig. 1, a supersonic wave cleaning machine has a power supply device 3, a ultrasonic driving apparatus 4 and some vibration (number that should be pointed out that vibration also can be 1) that is arranged in the cleaning fluid.Ultrasonic driving apparatus 4 comprises a signal and produces module 41, an output module 42 and a ultrasonic wave transducer module (transducer) 43.Power supply device 3 is electrically connected with household AC power, and AC power is converted into the working power of a direct current and exports signal generation module 41 reception working powers, and the first driving signal Vd1 of output AC.Output module 42 receives working powers, and receives first and drive signal Vd1, and adjusts first size that drives signal Vd1 and drive signal Vd2 to become second.
Ultrasonic wave transducer module 43 receives the second driving signal Vd2 and is arranged in the cleaning fluid, and output and second drives the ultrasonic wave of signal Vd2 same frequency.The ultrasonic wave transducer module is to make with piezoelectric ceramics (piezoelectric ceramic) element.When piezoelectric ceramics receives the second driving signal Vd2, can transfer second electric energy that drives signal Vd2 to mechanical energy, and generation and second drives the vibration of signal Vd2 same frequency.
Ultrasonic wave drives vibration and produces vibration, makes the sub-disturbance cleaning fluid of vibration.Because the viscosity (viscosity) of this cleaning fluid, the disturbance of cleaning fluid makes and himself produces many tiny vacuum microvesicles.Will break when utilizing the vacuum microvesicle in cleaning fluid, to run into to adhere to the dirt that cleans on the thing and make dirt produce strong vibration, and make dirt break away from thing to be cleaned surface, to reach the effect of cleaning thing to be cleaned by this kind vibration.
Consult Fig. 2, because the ultrasonic wave that existing supersonic wave cleaning machine sends has only a fixing frequency, and the ultrasonic wave with CF drives vibration generation vibration, but because vibration is to manufacture in the mode of sintering (sintering) to form, and its driving frequency of the vibration of making in this way can't be in full accord, therefore can only correspondingly drive the preferable vibration of vibration generation of particular drive frequency with the ultrasonic wave of fixed frequency, and can't make vibration all produce preferable vibration, so also just can't produce vibration, so the clean effect of this supersonic wave cleaning machine is relatively poor relatively with the common cleaning fluid that drives of whole vibration.

The specific embodiment
The present invention is described in detail below in conjunction with drawings and Examples:
Consult Fig. 3, Fig. 4 and Fig. 5, the ultrasonic driving apparatus 1 of tool multi-frequency scanning of the present invention, be applicable to that sending ultrasonic wave produces vibration to drive plural number vibration, and comprise a signal and produce module 11, an output module 12 and a ultrasonic wave transducer module 13, and be electrically connected with a power supply device 2 in the external world, power supply device 2 is electrically connected with the AC power of family expenses, and AC power is converted into the operating power of direct current.The DC voltage of power supply device 2 outputs one 12V produces the DC voltage of module 11, a 21V and a 320V to output module 12 to signal.Because power supply device 2 is not the improved emphasis of the technology of the present invention, and industrial quarters had many existing circuit can reach function corresponding, repeats no more herein.
Signal produces the first driving signal Vd1 that module 11 output frequencies change in a particular range.Signal produces module 11 and comprises an one scan unit 111 and an oscillating unit 112.
In the present embodiment, scanning element 111 comprises first integrated circuit 1111, and oscillating unit 112 comprises that second integrated circuit, 1121, the first integrated circuits 1111 and second integrated circuit 1121 are integrated circuits of existing numbering LM556, but not as limit.
Ultrasonic wave transducer module 13 receives second and drives signal Vd2, and output and second drives the ultrasonic wave of signal Vd2 same frequency.Produce ultrasonic wave in order to drive ultrasonic wave transducer module 13, second amplitude that drives signal Vd2 is in 200～500 volt range, and this ultrasonic wave transducer module 13 is converted to the mechanical energy that drives the vibration of vibration with the electric energy of the second driving signal Vd2.
Consult Fig. 6, suppose that the value of frequency correction signal Vadj is 0V.When the voltage of triangular wave Vm was 0V, first drove the frequency of signal Vd1 at minimum; Along with the voltage linear increase of triangular wave Vm, first drives also linear the increasing of frequency of signal Vd1; When the voltage of triangular wave Vm reached maximum, the frequency of the first driving signal Vd1 also correspondence reached maximum, and second value that drives signal Vd2 is that the first driving signal Vd1 is through being amplified to about 500 volts result.
If the voltage of frequency correction signal Vadj is for negative, then first frequency that drives signal Vd1 will be as shown in Figure 7.First drives signal Vd1 and first drives the result of signal Vd1 after with the frequency correction signal Vadj modulation frequency of this negative value among Fig. 6 among Fig. 7, and first drives the frequency of signal Vd1 when corresponding triangular wave Vm is 0V and first drive the frequency of signal Vd1 when corresponding triangular wave Vm is 0V in less than Fig. 6.
It should be noted that waveform that scanning element 111 also can export other shapes to oscillating unit 112, for example sine wave or square wave.When scanning element 111 output be sine wave the time because sinusoidal wave voltage with triangular wave Vm all is slowly to change in a specific scope, therefore also can make oscillating unit 112 output frequencies drive signal Vd1 at first of a particular range.And when scanning element 111 output be square wave the time because square-wave voltage only can change between two values, therefore first drive signal Vd1 correspondence had two frequencies, so can be used for driving two vibration.
Change in specific frequency range because first drives signal Vd1, therefore the frequency of ultrasonic of ultrasonic wave transducer module 13 generations also will change in specific frequency range, so vibration of different driving frequency can be driven and the generation vibration by the ultrasonic wave of corresponding frequency.
Comprehensively above-mentioned, can only produce the ultrasonic wave of a fixed frequency compared to existing ultrasonic driving apparatus 4, the ultrasonic driving apparatus 1 of tool multi-frequency scanning of the present invention is created in the ultrasonic wave of change frequency in the particular range, therefore vibration of different driving frequency can be driven to produce vibration, so the cleaning performance of the supersonic wave cleaning machine of the ultrasonic driving apparatus 1 of tool multi-frequency scanning of the present invention is better by the ultrasonic wave of corresponding frequency.
