Fully automatic floor washing machines are already very familiar to us. They can be found everywhere in major property communities, factories, supermarkets, and stations. However, if we use them for a long time, we will find that the charger of the floor washing machine is easily damaged. So what is the reason for this? Next, our YOUNISI after-sales personnel will analyze the reasons.

1. The voltage is unstable. The charger needs a stable voltage when working, especially the switching power supply charger. This kind of charger has higher requirements for voltage. During production, some factories have a very large demand for electricity due to the production equipment, which leads to unstable voltage in the entire workshop. Sometimes the voltage will even drop below 200 volts. So if we use the charger to charge the battery at this time, it is very likely that the charger will be damaged due to the low voltage.

2. The charger's fan fails. This failure is one of the common failures of many brands of chargers. Only a very small number of chargers do not use fans for heat dissipation. The vast majority of chargers use fans for heat dissipation. If the quality of the fan is not good enough, the fan will often be damaged or not rotate. This situation is fatal to the charger. Damage to the fan will cause the temperature inside the charger to be too high, thus burning out circuit boards and other accessories.

3. The dust in the use environment is very heavy, especially the dust in some workshops also contains some metal dust. These metal dust will enter the charger's circuit board from the heat dissipation holes of the charger. Over time, it will cause short circuits on the components on the circuit board, etc., thus damaging the charger.

Based on the above reasons, users of fully automatic floor washing machines are required to maintain the equipment as much as possible and stay away from the factors mentioned above, so as to ensure the service life of the charger.
