【摘要】 本文根据超声波雾化原理,在测得压电换能器振子谐振频率情况下,直接给换能器两端加上该频率下的振荡信号,测得的雾化效果作为一个参考量,然后通过Multisim 10仿真软件对雾化电路进行仿真,大致确定元件参数。在此基础上,通过实际电路调试,得到雾化能力在200-250mL/h的超声波雾化电路。更多还原

【Abstract】 The paper is based on the ultrasonic atomization mechanism,and the experiment loads the oscillation signal directly on the both ends of piezoelectric transducer at the same frequency and gets a reference about the atomization result after resonance frequency of the piezoelectric transducer has measured.Followed by a simulation of Multisim 10 simulation software for the atomization circuit and identify the main impact parameters.Finally,we get the ultrasonic atomization circuit with atomization ability about 200-250mL/h by debugging the actual circuit.更多还原
