During the use of the humidifier, it is often encountered in faults such as powerlessness, the humidifier does not have fog, and the water vapor regulating knob cannot work. It effectively solves these problems. We need to explore the working principle of the drill.
The reasons and solutions of the humidifier do not have fog
1.The moisturizer atomizer faults.Solution: Open the bottom cover and check if it is burning. If the insurance is good, try to adjust the potentiometer on the circuit board. Try it in a quarter of the circle clockwise. If it is a humidifier or no fog, it does not spray.Then consider replacing the atomized tablet. Generally, the atomizer of the humidifier is a metal round sheet with a diameter of about 20-30 mm under the spray port.It will not work properly, and it will cause the humidifier to not fog.
2.Generally, the humidifier work has two conditions: 1. The ceramic oscillator vibrates to produce water mist.2. The fan rotates and sends out the water mist.If the humidifier can operate but no water mist sprays, it may be a fan fault.Solution: It ’s too long to cause the fan card to die. Add a little lubricant to lightly pat it twice to let the fan turn again.
3.If the humidifier does not spray, no spray, no gas, the biggest reason is that the humidifier is not regularly cleaned and maintained.Generally speaking, it is better to clean the humidifier about once a week.
4.If the humidifier has wind and no fog, it may be used for a long time to use tap water. The stops of the stains cause the shocking tablet to condense the water and alkali. It cannot operate normally.Solution: Use household white vinegar to add some salt to effectively dissolve water and alkali.
Many of the faults of the humidifier are caused by scale. Therefore, the water storage tank and liquid level detection part of the humidifier should be cleaned frequently to prevent dirt from depositing. If possible, you can consider using pure water as a humidifier water.
Common fault maintenance
The atomized water vapor cannot blow out the shell
Maintenance: Open the heating device, plug in the power, and find that the fan does not turn.After removing the fan, the output of the switching power supply is 12V. Normal, then judge the fans of the fan. After replacing the fan, the fault is excluded.
There is no response to power.
Maintenance: The power supply is connected, and the measurement of 36V and 12V has no output. It is judged that it is a switching power failure.After disassembling the power supply of the switch, the rectifier part was dark. After measurement, the rectifier diode (1N4007) damaged one. After replacement, the fault was excluded.
Water vapor atomization is weak, and the adjustment knob can not work
Maintenance: After the measurement of 36V and 12V, the output of 36V and 12V, Q2 has no breakdown, each resistance container is not black, but it is found that there are more dirt in water storage tanks.Layer -layer scale, wash the meals and power on, power, and the atomization effect returns to normal.
Working principle of adding drills
After connecting the power supply, the switching power output 36V and 12V.When the water storage tank has not been placed in the base or water storage tank, the magnet is far from the cooker, the dry reservation bounces. QL is turned on, the lack of water is bright, the work indicator D2 is destroyed;Voltage, ultrasonic circuit does not afford.When the water storage tank is added with an appropriate amount of water, the magnet is close to the scouts, and the cooker is sucked and combined. The QI is cut off because its base becomes high.After R6, the circuit of the ultrasonic occurrence was sent to the ultrasonic circuit through the R5 and RT1, and the ultrasonic circuit vibration was vibrated to produce fog. The fan was blown out of the shell to achieve the effect of indoor humidification air.
