Description
Technical field
The utility model belongs to ultrasonic technology field, specifically, relates to a kind of ultrasonic transducer and throw-in type ultrasonic cleaning equipment.
Background technology
Existing piezoelectric ceramic transducer is of a great variety, but the problems such as ubiquity resonant frequency is higher, piezoelectric ceramics is frangible, transducing product heat conduction efficiency difference.
Existing Ultrasonic Cleaning rod scheme is as the utility model " throw-in ultrasonic cleaning rod " of CN201516427U, it can only use single-frequency, but in actual life, different dirts and different purposes are needed to different ultrasonic frequencies to process, existing scheme lacks regulating frequency device, do not reach best cleaning effect, do not realize multiple use.
Utility model content
The purpose of this utility model is to overcome the weak point existed in above-mentioned technology, provides a kind of lower resonant frequency and piezoelectric ceramics not breakable transducer, and a kind of frequency-adjustable of this transducer designs supporting, multi-purpose ultrasonic wave rod.To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of ultrasonic transducer, as shown in Figure 1, is made up of metal electric polar ring, piezoelectric ceramic piece, metal biography energy block, bolt.Metal electric polar ring, metal pass can all have two by block, piezoelectric ceramic piece is ring-type, there are three, first metal passes can have a bolt hole in block axle center, second metal passes and block can be provided with the nut matched with bolt, above-mentioned parts pass the sequential combination of energy block, first piezoelectric ceramic piece, first metal electric polar ring, second piezoelectric ceramic piece, second metal electric polar ring, the 3rd piezoelectric ceramic piece, second metal biography energy block according to first metal, and by bolt through with the axle center of upper-part, each parts being fixed as a whole.
Because the main scope of application of domestic ultrasonic Multifunctional stick is in water, certain this expanding function is even operated in hot environment, and therefore, the waterproof heat-resisting design of domestic ultrasonic Multifunctional stick is very crucial.So on the basis of such scheme, ultrasonic transducer can also comprise shell, connecting rod, sealing device.Described shell can have various shape, it the preceding paragraph is fallen described in ultrasonic transducer be wrapped in wherein, the shape of shell is preferably a cylindrical hollow housing.Connect for the ease of circuit and hand-held, it also comprises a connecting rod, and connecting rod and shell are connected by bolt mode or as a whole with housing, and connecting rod is preferably cavity bar.In order to waterproof, also comprise sealing device, it is a packing ring, preferred double-layer seal rings, and described double-layer seal rings is placed in shell and metal passes between energy block, and when connecting rod is connected by bolt mode with shell, sealing device also comprises a small sealing ring.
A kind of multifunction ultrasonic rod, be made up of above-mentioned ultrasonic transducer and ultrasonic drive circuit, two output electrodes of drive circuit are connected with second metal electric polar ring with first metal electric polar ring of transducer respectively, and drive circuit is fixed on connecting rod or is placed in connecting rod or independent placement.Ultrasonic drive circuit is made up of power unit, pulse oscillation circuit, impedance matching circuit.
Power unit is dc source, and it can be adopted powered battery or use by after the filtering of family expenses 220V AC rectification;
Power control circuit, because different cleaning loads needs different ultrasonic powers, so we are by regulating the demand realizing different cleaning loads to the power output of ultrasonic power.Power adjusting adopts step power regulation.During piezoceramic resonance, as long as change the voltage magnitude at its two ends and adjustable output power of power supply.In order to obtain the voltage signal of many grades, pressure regulation can be realized by rectifier transformer or high frequency transformer.Directly select the different number of turn coil tap in high frequency transformer secondary limit by switching device, obtain the different voltage magnitudes being supplied to load, reach the object of regulating power.
Purposes of the present utility model has two kinds, and one is for cleaning of objects, as the incrustation scale etc. of teacup.Supersonic wave cleaning machine is based on the general principle work of cavitation effect, and compared to traditional craft cleaning or mechanical cleaning method, the cleaning of using ultrasound ripple has power saving, water saving, easy to use, cleaning performance unanimously, not stay the advantages such as dead angle.The second purposes is that ultrasonic extraction reduces the active force between target extract and sample matrices mainly through the Quick mechanical vibration wave that PZT (piezoelectric transducer) produces thus realizes solid, liquid extract and separate for extraction, it
, that recovery rate high, extraction time short advantage low with Extracting temperature is used to the extraction of Chinese medicine and various animal and plant effective content, is to substitute tradition to shear the modern high technology means that process realizes efficiently, energy-saving and environmental protection formula is extracted.
The beneficial effects of the utility model are:
(1) project organization of ultrasonic transducer both make use of the longitudinal effect of piezoelectric ceramic vibrator, and lower resonant frequency of having got back, achieves the optimization of performance;
(2) ultrasonic transducer is by adopting left and right biography energy block and pre-stressed bolt to piezoelectric ceramic wafer Shi Hanzhang, piezoelectric ceramic wafer is made to be in compressive state all the time when strong vibration, thus breaking of piezoelectric ceramic piece can be avoided, reach the object improving power capacity and change frequency;
(3) the large-area metal of ultrasonic transducer passes and can the heat conductivility of transducer is very significantly improved block;
(4) frequency-adjustable of multifunction ultrasonic rod, can regulate different ultrasonic frequencies according to different dirts and different purposes, thus reaches best effect;
(5) multifunction ultrasonic rod water-proof sealing, can be used for multiple environment.
