Described locking nut is provided with the staged through hole, and described nozzle piece is arranged on the middle part of described staged through hole, and described nozzle piece center is provided with one and sprays micropore;
The lower end of described cavity main body assigns in the staged through hole of described locking nut.
Preferably, be provided with the O RunddichtringO between described crystal oscillator and described cavity main body.
Preferably, be provided with the O RunddichtringO between described nozzle piece and described cavity main body.
Preferably, described nozzle piece to the distance of described crystal oscillator at 0.1mm between the 1mm.
Technique scheme is the effect of liquid by inlet opening and fluid hole, makes the formed enclosed cavity of cavity main body, crystal oscillator and nozzle piece is full of the certain pressure intensity difference with injection micropore external environment liquid.When the ultrasonic wave high speed simple harmonic motion of crystal oscillator, the pressure of the liquid between crystal oscillator and nozzle piece will produce the periodic regularity that is sine wave characteristics along with the ultrasonic wave high speed simple harmonic motion of crystal oscillator to be changed, and with the pressure reduction stack of liquid self; When the hydraulic pressure of stack reaches a certain critical value, liquid will be from spraying the micropore ejection, then along with the decline of hydraulic pressure, lowly stops during to this critical value.When the next vibration period arrives, repeat to spray the liquid of identical quantity again.The spray volume in each cycle is decided by to spray the long-pending size of lateral cross section of micropore and departs from and sprays the outer pressure difference of micropore and quantize, and the size that at every turn sprays amount of liquid can be calculated by the harmonic period number of monitoring crystal oscillator and confirm.The control ratio manually-operated of this liquid measure is accurate, and experimental result is more reliable, and production efficiency is higher, is applicable to the field such as chemical industry, biochemistry, medical and health, air brushing, high speed printing of precision, mass.
