你說的應該是反饋的吹風機吧?
基本上直流的吹風機已經是主流很多年了
近來市場上推出很多帶反饋的吹風機,聲稱能把電壓控制在非常低的範圍.
這個概念非常好, 不過製造技術可能還要一段時間去發展成熟.
一般這種反饋的傳感器可分為外置和內置兩種.
內置的造價會比較便宜,不過因為太接近離子針,準確度比較難控制
外置的除了可以感應離子風外, 還可以同時感應帶電物件的電壓,操控吹風機加快中和
速度
不過外置的傳感器造價較高,而且安裝位置對感應有很大的影響,對技術員的要求也比
較高.

通常离子风机为交流型，其离子风在一定时间段内能达到+/-50V已经是相当不错
了。如果从中分别取几个瞬间，你可以看到其电压是一直在波动着。现在有一种新的
离子风机叫直流离子风机，它可以反馈前方工作区的电压极性，发射出相反的电荷进
行中和，能够将工作区内的电压控制在+/-5V之内！

各位好
请教大家一个问题，离子风机和离子风扇风电压的控制应该是在多少范围之内，或
者有什么相关的参考标准，请提供小妹参考，谢谢
