摘要
该文基于亥姆霍兹共振腔设计了一个香味自动排放装置,可以应用到洗手间的香味自动排放。当检测到有人使用洗手间后,光电开关会自动触发单片机,启动正弦信号发生器,产生亥姆霍兹共振腔的共振频率信号,此时共振腔就会排放出香味,净化空气。
The paper introduced the design of fragrance automatic discharge device based on the Helmholtz resonance cavity,which can be applied to automatic smell discharge in the washroom.After the detection of the people using the washroom,the photoelectric switch triggers the microprocessor automatically to start the sinusoidal signal generator and produce the signal which frequency is same as the Helmholtz resonance cavity resonance frequency,then the resonance cavity emits fragrance for air purifi cation.
