例1 故障现象:开机电源指示灯亮,风机运转正常,但不出雾。分析检修:风机运转正常,说明雾化器供电正常,保险丝完好(整机电路如附图所示)。无雾化现象应首先检查水槽内药液液位是否正常,液位不宜过高更不能过低;再检查水槽内的磁性浮于是否浮起。若两者均正常,则应打开后盖或从水槽下将雾化器拆下移开,检查雾化器内部的电路板及元器件。首先检查超声换能器是否接触不良或老化损坏。检查方法可用替换法即可判断,注意通电开机检测前,水槽内
Example 1 Symptom: power indicator light is on, the fan is operating normally, but not fog. Analysis and maintenance: fan is operating normally, indicating normal nebulizer power supply, the fuse intact (the whole circuit shown in the figure). No fog phenomenon should first check the liquid level in the tank is normal, the liquid level should not be too high can not be too low; then check the tank within the floating magnetic float. If both are normal, either open the back cover or remove the nebulizer from under the sink and inspect the circuit board and components inside the nebulizer. First check the ultrasonic transducer is bad or aging damage. Check the method can be used to determine the replacement method, pay attention to power on before testing, the sink
