Abstract

The invention discloses a multifunctional power adapter. A driving motor drives a take-up wheel, a power line is wound on the take-up wheel and gradually forms a solenoid, a contact is in sliding contact with a spring piece, a signal detection unit inputs alternating test current to the solenoid through the spring piece, and the solenoid generates a first alternating magnetic field; the reference unit forms a second alternating magnetic field and changes complex impedance in a solenoid, the signal detection unit transmits the sensed complex impedance change condition to the signal processing unit and obtains a current complex impedance value, and when the current complex impedance value falls into a complex impedance interval range, the driving motor stops rotating, and take-up is finished; when the marked impedance value is detected, paying off is finished; the signal detection unit obtains the equivalent resistance value and compares the equivalent resistance value with the reference resistance value, and when the current resistance value is larger than the reference resistance value, the power line has an aging condition endangering electricity utilization safety, and a user is reminded to replace the power line. Flexible and automatic take-up and pay-off are achieved, and the aging condition of the power line is detected.

Description

technical field [0001] The invention relates to the technical field of power adapters, in particular to a multifunctional power adapter and a method for using the same. Background technique [0002] The power adapter is a power conversion device for small portable electronic equipment and electronic appliances. It is generally composed of housings, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is to convert AC mains power into available electrical appliances directly. The DC power used; according to the connection method, it can be divided into wall-plug type and desktop type, and is widely used in tablet computers, smart phones, security cameras, set-top boxes and other equipment. [0003] During the long-term use of the tablet power adapter, the power cord is repeatedly twisted due to random winding or rough winding, which is prone to mechanical fatigue and increased resistance, which will cause the power cord to a...
