Detailed ways

Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.

An overcharge protection smart socket, comprising a housing 1, a plug 2 and a control chip 3 disposed inside the housing 1, wherein the control chip 3 includes a current sensor, a switch circuit and a control circuit, and the current sensor is connected to the The switch circuit and the plug 2 are connected to the control circuit, and the switch circuit is connected to the control circuit and the power supply through lines respectively.

The control principle of the present utility model is:

1. Solve the problem of overcharging

When the mobile phone battery is not saturated, the control chip is in the open state, and the current can be charged through the smart socket. After reaching the current range of the trickle charge, it will be detected by the current sensor, and the command will be sent to the control unit after the judgment. The control unit transmits the corresponding instructions to the switch circuit, and then through the switch circuit, the state of the on-circuit is changed to the state of the off-circuit, and the mobile phone will no longer be charged at this time;

2. Solve the problem of using charging while charging

When the mobile phone is charging while using it, the charging current is greater than the practical current consumption in most cases. However, the trickle charging current of the mobile phone at this time will be greater than the trickle current when the mobile phone is not in use. At this time, the smart socket judges that the mobile phone is charging at this time. When it is not in use, the normal trickle current is reached. The control chip in the smart socket receives instructions and changes from the on-circuit state to the off-circuit state. When the use consumes a certain amount of power, the battery is no longer In a saturated state, when an instruction is issued at this time, the control chip in the smart socket receives the instruction and switches from the disconnected state to the connected state to continue charging;

3. Solving the problem of energy waste

When the mobile phone battery is saturated, the smart socket automatically cuts off the power through the control chip to avoid unnecessary energy waste;

4. Solve the problem of battery loss

After the battery of the mobile phone is in a saturated state, continuing to charge will make the battery in an oversaturated state, which will shorten the battery life of the mobile phone. Using a smart socket can prevent damage to the battery of the mobile phone.

The above embodiments are only to illustrate the technical ideas of the utility model, and cannot limit the protection scope of the utility model with this. Any changes made on the basis of the technical solutions according to the technical ideas proposed by the utility model all fall into the scope of the utility model. within the scope of the new protection.
