Abstract

The invention relates to a charger with an automatic power-off function. When a plug is inserted into a power source socket, the charger is connected with press springs of an internal housing and an external housing; an internal housing stopping hook hooks up an external housing stopping hook; a metallic spring plate fixed on the internal housing is connected with metallic contact points fixed onthe external housing to enable a charging circuit to charge a battery; when the battery is fully charged, a switch control circuit is conducted, an electric magnet is magnetized to suck the tail end of the external housing stopping hook for separating the internal housing stopping hook from the external housing stopping hook; and simultaneously, the metallic spring plate is disconnected with the metallic contact points. When the plug is inserted into the power source socket, the charger can automatically conduct the power supply, and automatically switch off the power supply after the batteryis fully charged, so that the energy waste is avoided; and the battery is prevented from being damaged due to long-time charging.

Description

technical field [0001] The invention relates to a charger, in particular to a charger with an automatic power-off function. Background technique [0002] At present, the commonly used chargers on the market only rely on the indicator light to remind the battery that the battery is fully charged after the battery is fully charged, but the internal circuit of the charger is not turned off. Due to various reasons, we cannot cut off the power supply of the charger in time after the battery is fully charged, which will cause a great waste of energy. Taking the mobile phone charger as an example, the mobile phone charger is 100mw per hour, and it consumes an extra hour per day. There are 10 million mobile phones consuming electricity, so the country will lose 1 million watts of electricity every day. In addition, if the battery is fully charged and then continues to charge, the battery will be in a floating charge state, which will cause part of the electric energy not to be full...
