摘　　要：微网雾化器核心器件是雾化片,基于雾化片的工作原理和电路谐振相关知识,设计了驱动雾化片工作的各部分电路。在Multisim仿真软件中配置升压振荡电路各元件参数的基础上,完成了硬件电路设计,并通过追频检测电路确定谐振频率(110±5)kHz雾化片的最佳驱动频率为110 kHz。对雾化颗粒的粒径和雾化速率的检测证实了驱动谐振频率(110±5)kHz雾化片的合适谐振频率为110 kHz。在该频率驱动下,雾化器中粒径低于5μm的颗粒占比为67.97%,雾化速率为0.39 mL/min。The core component of the micro-mesh atomizer is an atomizing sheet.Based on the working principle of the atomizing sheet and the related knowledge of circuit resonance,the present paper designs various parts of the circuit to drive the atomizer.The components of the boost oscillator circuit are configured and simulated by the Multisim software.On the basis of the simulation,the hardware circuit design is completed,and the optimal driving frequency of the atomizer with a resonance frequency of(110± 5) kHz is determined to be 110 kHz through the frequency tracing detection circuit.By detecting the particle sizes of the atomized particles and the atomization rate,it can be verified that the appropriate resonance frequency of the atomizing sheet with a driving resonance frequency of(110±5) kHz is 110 kHz.Driven by this frequency,the proportion of the particles with the diameters less than 5 μm is 67.97 %,and the atomization rate is 0.39 mL/min.
