Abstract
The utility model relates to an auto-power outage charger, which comprises a power supply, a spring, a coil, a magnetic core, a switch, a diode and a rechargeable battery. The power supply, the switch and the rechargeable battery are connected in series to form an outer circuit, the coil, the diode and the rechargeable battery are connected in series to form an internal circuit, the coil is wound on the outer of the magnetic core, the middle part of the magnetic core is insulator, one end of the magnetic core is connected with the switch of the outer circuit, and another end of the magnetic core is connected with the spring. When we need charge, firstly the switch is closed, the two circuits are through, but the current does not pass through the internal circuit because of the one-way conductivity of the diode. When the battery is fully charged, the voltage of the internal circuit arrives the maximum, the diode is conductive, the current which passes through the coil greatly changes in an instant, the magnetic coil of the internal circuit generates a big enough escaping force, the switch can be auto-outage. Both of the two circuits disconnect at that time, the auto-outage purpose can be achieved. The utility model has the advantages of simple structure, easy use and resources conservation.
Description
Technical field
The utility model relates to a kind of charger, specifically a kind of charger that can cut off the power supply automatically.
Background technology
We know, existing various charger, no matter how form changes, and all has a common shortcoming, exactly after battery is full of, can't automatic disconnection, thereby make us grasp the charging interval, charging interval deficiency often, the life-span or the charging interval that reduce battery are too of a specified duration, battery is washed out, and then cause very big waste.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy to use, charger that can cut off the power supply automatically of effectively avoiding waste is provided.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of charger that can cut off the power supply automatically, it includes power supply, spring, coil, magnetic core, switch, diode and rechargeable battery, power supply, switch and rechargeable battery are composed in series external circuit, coil, diode and rechargeable battery are composed in series interior circuit, coil is around the outside of magnetic core, the magnetic core mid portion is an insulator, and magnetic core one end connects the switch on the external circuit, and the magnetic core other end connects spring.
The utility model adopts has increased an interior circuit and a switch on the basis of original charger, when we need charge, earlier switch to be closed, this moment, two circuit all led to, but in the interior circuit because the unilateral conduction of diode, so there is not electric current to pass through.After battery was full of electricity, it is maximum that the voltage of interior circuit can reach, diode conduction, and the electric current that passes through in the coil is very big in instantaneous variation, the enough big power of breaking away from of magnetic coil generation in the circuit in making, switch can automatic disconnection.At this moment two circuit all can disconnect, thereby reach the purpose of automatic outage.The utlity model has simple in structure, easy to use, advantage such as economize on resources.
Description of drawings
