Mobile phone emergency charger with hand strength practice function

Abstract

The invention discloses a mobile phone emergency charger with a hand strength practice function, comprising a rubber ring, a permanent magnet, a coil, binding posts, a rectifier module, a shell A, a shell B, and the like. Users can practice the hand strength by repeatedly pressing and releasing the rubber ring. The permanent magnet and the coil connected to the rubber ring are repeatedly plugged in and pulled out, the conductor of the wire continuously cuts the magnetic lines of force of the permanent magnet, and thus, an induced current is produced in the coil. When the number of turns of the coil is enough, a voltage can be produced to charge a mobile phone. The induced current of the coil is rectified by the rectifier module and then charged into the battery of a mobile phone. The beneficial effect is that the charger achieves both functions of hand strength practice and mobile phone emergency charging.

Description

technical field [0001] The invention relates to a mobile phone emergency charger with the function of hand strength training. It belongs to both the field of sports equipment and the field of household appliances. Background technique [0002] The results of a large-scale survey in the United Kingdom show that people with strong grips are more likely to live longer than people with "no strength to restrain chickens". The results of the study show that grip strength will decrease with age. The average grip strength of middle-aged women is 27 kg, and that of middle-aged men is 40 kg. For every 1 kg increase in grip strength, the mortality rate can be reduced by 3%. It can be seen that practicing more hand strength will definitely help to increase life expectancy. The commonly used equipment for practicing hand strength is a ring grip, which has different exercise methods such as one hand, two hands, upper grip, lower grip, and double clamps. Using grip strength exercise can...

Problems solved by technology

In order to solve this problem, many people adopt the dual-battery and double-charge configuration scheme when buying mobile phones to solve the problem of large power consumption, but the second battery still faces the problem of running out of power and affecting the normal use of the mobile phone.

In order not to affect the work of the mobile phone due to the exhaustion of power, people have invented charging treasures and other emergency power sources, such as solar chargers, etc. Large size, inconvenient to carry; solar charger can only be used when the weather is sunny
