Keeping the air in the room fresh is the premise of people's healthy life. People are more and more focused on health and therefore more willing to invest in health while maintaining normal daily life. As a result, air purifiers have quietly entered people's lives, but how to use them correctly to prolong their life is confusing to most people. Below, the editor will answer the obstacles that you may encounter in the process of using air purifiers in daily life. Learn how to maintain it and let us breathe fresh air from time to time.
working principle:
Air purifiers are usually composed of high-voltage circuits, negative ion generators, fans, air filters and other systems. When the purifier is running, the fan in the machine circulates the air in the room and the car. After the polluted air is filtered by the air filter in the machine, various pollutants are removed or adsorbed, and then generated by the negative ions installed in the air outlet. The device ionizes the air continuously, and generates a large amount of negative ions, which are sent out by the micro-fan to form a negative ion flow to achieve the purpose of cleaning and purifying the air.
common problem:
1. The high voltage indicator light does not light up, and the fan does not rotate. Please check in the following order:
(1) Check whether the fuse is blown. If it is broken, find out the reason and then replace it.
(2) Check whether the coil of the step-up transformer is burnt out. Use a multimeter to measure its resistance. If the coil is open or short-circuited, the transformer of the same type should be replaced.
(3) Check whether the rectifier tube and capacitor of the voltage doubler rectifier circuit are damaged, and whether the oscillator stops vibrating. Use a multimeter to test the relevant components one by one, and replace the burned components to eliminate the fault.
2. The high voltage indicator light is on, but the fan does not rotate.
First, check whether the fan blade is stuck by foreign objects and whether the bearing is seriously worn. If there is no abnormality, then check whether the motor lead is open and whether the winding is damaged. It can be measured with a multimeter. If the windings are open or short-circuited, the fan motor of the same specification should be replaced.
3. The negative ion generator ignites between the poles.
Use tweezers to correct the pole piece first, if it still fires, you can move the air purifier to a dry place to try it out, and the fault can generally be eliminated.
4. The negative ion output concentration is low.
First remove the dirt on the filter screen and electrode, correct the positive and negative plates, if it is invalid, then check the high-voltage generating circuit. Check the step-up transformer, rectifier tube, capacitor, etc. with a multimeter.
