背景技术Background technique
近几年来，随着科学技术的快速发展，手机的不断换代，人们对手机的依赖不断增加，同时在手机上花费的时间也在不断增加。目前手机在充电过程中需要人工去插上USB接口，同时只能显示充电电量，但不能自动充断电和断开输出端的USB接口，因此时常会造成手机工作在断续充电状态，这样不仅消耗电能，而且手机电池的寿命将大大减少。在手机电池充电包括降阻、降压和整流三个环节。而降阻实际上就是电池储存能量的过程。手机工作时电池输出能量，电池电阻不断增加直至显示没电。降压将输入的交流电的110V或220V电压降至手机的工作电压5V、9V或12V。而整流将输入的交流电转换成直流电。当手机结束充电后，充电的降阻环节已经完成，而充电器降压和滤波环节继续工作，然而这样工作电路本身就有能量的消耗，而且长时间在通电状态下将减少充电器内部元器件的使用寿命。此外，充电器内的铁芯也会在工作中发热、轻微振动和释放电磁波。因此，过量充电不仅会对手机的性能和使用寿命产生影响，而且还会造成能源浪费和环境污染。In recent years, with the rapid development of science and technology and the continuous replacement of mobile phones, people's dependence on mobile phones has been increasing, and the time spent on mobile phones has also been increasing. At present, the mobile phone needs to be plugged into the USB interface manually during the charging process, and at the same time, it can only display the charging power, but it cannot automatically charge and disconnect the USB interface of the output end, so the mobile phone often works in an intermittent charging state, which not only consumes power, and the battery life of the mobile phone will be greatly reduced. Charging the mobile phone battery includes three links: resistance reduction, voltage reduction and rectification. The resistance reduction is actually the process of storing energy in the battery. When the mobile phone is working, the battery outputs energy, and the battery resistance continues to increase until it shows no power. The step-down reduces the 110V or 220V voltage of the input AC power to the mobile phone's working voltage of 5V, 9V or 12V. And rectification converts the incoming alternating current into direct current. When the mobile phone finishes charging, the charging resistance reduction link has been completed, and the charger step-down and filtering links continue to work. However, the working circuit itself has energy consumption, and the internal components of the charger will be reduced when it is powered on for a long time. service life. In addition, the iron core in the charger will also generate heat, vibrate slightly and release electromagnetic waves during operation. Therefore, overcharging will not only affect the performance and service life of the mobile phone, but also cause energy waste and environmental pollution.
目前国内这只有自动断电的充电器有的采用时间继电器、继电器、发光二极管或电磁铁等原理制作的。而采用时间继电器或电磁铁原理制作的自动断电充电器具有不灵活、非智能的缺点，比如时间继电器通过预先设定时间，当规定时间达到后就切断开电路，而不能自我识别手机电池是否充满电，因此未在手机上获得普及应用，而发光二极管则多用在电动车等大型充电器中。在手机等产品在整个寿命周期中，电池电能的消耗有三分之二来自于手机充电器的消耗，即手机在充满电后充电器仍插在插座上的电力消耗。因此，充电器长时间接通电源时将减少元器件的使用寿命，并且元器件易发热，由此还会埋下火灾安全隐患。At present, there are only chargers with automatic power-off in China, which are made by the principles of time relay, relay, light-emitting diode or electromagnet. However, the automatic power-off charger made by the principle of time relay or electromagnet has the disadvantages of being inflexible and non-intelligent. It is fully charged, so it has not been widely used in mobile phones, and light-emitting diodes are mostly used in large chargers such as electric vehicles. During the entire life cycle of products such as mobile phones, two-thirds of the battery power consumption comes from the consumption of the mobile phone charger, that is, the power consumption of the mobile phone when the charger is still plugged into the socket after it is fully charged. Therefore, when the charger is powered on for a long time, the service life of the components will be reduced, and the components are prone to heat, which will also bury a fire safety hazard.
