超声雾化器是一种小型医疗保健设备,对于咽炎、喉炎、鼻炎、呼吸道急慢性支气管炎,肺气肿等病症有明显的疗效,此外,还可用于面部美容。现以天津 ZS——2001A 型超声波雾化器为例,将其常见的故障及检修介绍如下:1.指示灯不亮,晶片不起振。此故障多为 BU406损坏所致。BU406起着高频振荡电路的形成及功率输出的作用。由于长时间的使用及环境湿度的影响,会造成内部电子元器件锈蚀,轻则会使其参数发生改变,严重时即造成其 ce 结击穿短路。这时只能更
Ultrasonic nebulizer is a kind of small-scale health care equipment. It has obvious curative effect on pharyngitis, laryngitis, rhinitis, respiratory tract chronic bronchitis, emphysema and other diseases. In addition, it can also be used for facial beauty. Now take the Tianjin ZS-2001A ultrasonic atomizer as an example, and introduce its common faults and repairs as follows: 1. The indicator light is off and the wafer does not start to vibrate. This fault is mostly caused by damage to the BU406. BU406 plays a role in the formation of high-frequency oscillation circuits and power output. Due to the long-term use and the influence of environmental humidity, the internal electronic components will be rusted, and the parameters will be changed from light to heavy, causing serious short circuiting of the ce junction. It can only be more
