1、 Common troubleshooting
No atomization or low atomization amount
Power and circuit inspection: Confirm that the power indicator light is on and the voltage is stable. If the indicator light is not on, check whether the power cord, fuse, and switch are normal. If there are burn marks or component detachment on the circuit board, it is necessary to contact a professional for repair.
Water level and reed switch malfunction: Low water level can cause the reed switch to fail to conduct and the oscillation circuit to malfunction. Check if the water level in the sink submerges the sound transmitting membrane, if the float is stuck or damaged, and replace the reed switch if necessary.
Transducer (chip) issues: Aging of the chip, accumulation of scale, or surface corrosion can lead to a decrease in atomization efficiency. Use a multimeter to check the resistance of the chip. If the resistance of the inner and outer rings is zero or infinite, the chip needs to be replaced; If there is scale on the surface, soak it in a special cleaning agent and wipe it off.
Oscillatory circuit fault: Check whether the transistor, capacitor, inductor and other components are damaged. For example, if the amplification factor of the transistor is close to zero, it is necessary to replace the same type of component; If the capacitor fails, it will cause the oscillation frequency to shift, and the matching capacitor needs to be replaced.
The fan does not rotate or the air volume is insufficient
Check if the resistance of the fan coil is normal. If the resistance is abnormal or if you smell a burnt smell, replace the fan.
Confirm if the 12V power output is normal. If the switch power supply is faulty (such as damaged MOSFET), repair or replace the power module.
Abnormal indicator light or alarm
If the water level light is not on but the power light is normal, it may be due to a broken circuit in the reed switch circuit or the float not floating.
When the overheat protection alarm is triggered, it is necessary to stop the machine for 15 minutes and replace the cold water in the sink to avoid prolonged continuous use.
2、 Key maintenance points for transducers
Regular cleaning: Clean the surface of the chip every two weeks with a soft cloth or specialized cleaning agent to avoid scratching with hard objects. If the water quality is poor (such as in hard water areas), the cleaning cycle needs to be shortened.
Water quality management: Use pure water or distilled water, and prohibit direct addition of chemical solutions to prevent scaling or corrosion on the surface of the chip.
Storage environment: When not in use for a long time, empty the sink and store in a dry, ventilated place, avoiding direct sunlight.
Replacement cycle: Chips are consumables, and if there is a significant decrease in atomization efficiency or abnormal heating, they need to be replaced in a timely manner.
