1. Power supply type
Household ventilator power supply is mainly divided into internal power supply and external power adapter two kinds.
Built-in power supply: Some home ventilators use a built-in power supply design, that is, the power module is directly integrated inside the machine. This design simplifies the external connection and reduces the clutter of cables, but it is necessary to pay attention to the heat dissipation and maintenance of the machine to avoid damage to the internal power supply due to overheating.
External power adapter: Most home ventilators use an external power adapter, which converts mains power to the voltage and current required by the ventilator through a stand-alone power adapter. This kind of power adapter technology is mature, practical work, low failure rate, and easy to replace and maintain.
2. Using precautions
Correctly connect the power supply: Before use, ensure that the power cable is firmly connected without damage or aging. At the same time, the power socket that meets the requirements of the ventilator should be selected, and the use of inferior sockets or extension cords should be avoided.
Avoid leaving the power supply unplugged for a long time: Although the technology of the power adapter is mature and durable, leaving the power supply unplugged for a long time may cause the aging of internal components to accelerate, increasing the risk of failure. Therefore, it is recommended to unplug the ventilator when it is not in use.
Use backup power: In response to unexpected situations such as power outages, it is recommended to equip home ventilators with backup power (such as batteries or UPS uninterruptible power supply) to ensure continuity of treatment
3. Common problems and solutions
If the power indicator is off, first check whether the power plug is plugged in and whether the socket has power. If yes, the power adapter may be faulty and you need to replace it with a new one.
