Fig. 2 is embodiment two structural representations of the present utility model.
Fig. 3 is the A place enlarged drawing of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Embodiment one:
As shown in Figure 1, the utility model comprises table top 5 and frame 6, table top 5 lower devices have at least one excess sound pressure electric tachometer indicator 1 and at least one magnetostrictive vibrator 2, in the present embodiment, device has two excess sound pressure electric tachometer indicators 1 and a magnetostrictive vibrator 2, and the quantity of excess sound pressure electric tachometer indicator 1 and magnetostrictive vibrator 2 can determine according to actual needs.Excess sound pressure electric tachometer indicator 1 connects ultrasonic-frequency power supply 7 by ultrasonic cable link 9, and magnetostrictive vibrator 2 connects magnetostriction power supply 8 by cable link 10.Excess sound pressure electric tachometer indicator 1 is formed (enlarged drawing is referring to Fig. 3) by coupling block 12, two piezoelectric ceramic pieces 13, two plate electrode sheets 14, match block 15, prestressing force screw 16 and hold-down screws 3, excess sound pressure electric tachometer indicator 1 arrives table top 5 times by hold-down screw 3 and glue fixture, and the ultrasonic cable link 9 that connects ultrasonic-frequency power supply 7 is connected on the two plate electrode sheets 14.Magnetostrictive vibrator 2 is made up of vibration pedestal 4, line bag 20, magnetic core 21 and vibration ring 22, and magnetostrictive vibrator 2 is by vibrating mode device that pedestal 4 casts by bonding, welding or one below table top 5.Because the low frequency magnetostriction vibration of vibration of the high frequency piezoelectric ceramic of excess sound pressure electric tachometer indicator 1 and magnetostrictive vibrator 2 acts on table top 5 simultaneously, makes the utility model possess the complex vibration of little amplitude of high-frequency and low frequency large-amplitude vibration simultaneously.On the table top 5 above excess sound pressure electric tachometer indicator 1 and the magnetostrictive vibrator 2, be provided with the groove 501 that to take liquid in, in groove 501, can pour liquid into, the low-frequency vibration of the dither of excess sound pressure electric tachometer indicator 1 and magnetostrictive vibrator 2 and changes of magnetic field, can produce cavitation and magnetization to the liquid in the groove 501, thereby possessed functions such as cleaning, dispersion, homogeneous, atomizing, catalysis, alcoholization, magnetization, extended use category of the present utility model greatly.In the present embodiment, table top 5 is made by metal material, because the dither energy more easily transmits in metal material, and is difficult for transmitting in nonmetallic materials.
Embodiment two:
As Fig. 2, shown in Figure 3, on the basis of embodiment one, through hole 502 is set on table top 5, weld or be provided with the set bolt 19 of one with it on the radiant panel 11, radiant panel 11 is connected with the coupling block 12 of excess sound pressure electric tachometer indicator 1 by hold-down screw 3, and by seal washer 17 and hold-down nut 18 with set bolt 19 with excess sound pressure electric tachometer indicator 1 sealing device in through hole 502, identical among the mounting means of magnetostrictive vibrator 2 and the embodiment one.Adopt that excess sound pressure electric tachometer indicator 1 and radiant panel 11 are by the mounting structure of through hole 502 in the present embodiment, table top 5 can be made by metal material or nonmetallic materials, the energy loss in the time of can reducing the dither transmission like this and pass table top 5.
