At present, there are more than 2 billion mobile phones in the world, and more than billions of other small electronic products (digital products, notebook computers, etc.), and most people use these products to avoid trouble. The charging power supply is plugged into the power socket for a long time, and it is directly plugged into the mobile phone or electronic product when it needs to be used. This will inevitably cause the power consumption of the charger when it is not in use. According to the analysis of normal living habits, the actual daily use time of the charging power supply is not enough. More than 8 hours, and the other 16 hours are completely in the waste of electric energy that is not used. According to the current international energy saving requirements, the static loss of charging power supply is 0.3W per hour, and the charging of 2 billion mobile phones or electronic products per hour The static power loss of the power supply is 600,000 kilowatts, and the wasted power for 16 hours is: 9.6 million kilowatts. The waste of charging power supply power is extremely huge; and the product has a high safety risk. If there is a problem with the quality of the charger, plug it in for a long time There will be safety hazards such as temperature rise and fire during work, and if it is plugged into the power supply for a long time, the internal parts of the charger power supply will work for a long time, and the life of the parts will gradually decrease, which will greatly reduce the life of the charger, resulting in waste of resources and damage to the environment.

Utility model content

The technical problem to be solved by the utility model is to provide a standby zero power consumption, which can stop the charging power supply in the state of zero loss when there is no charging load, automatically start the power supply when in use, and can detect the actual current and actual temperature of the equipment , Accurately determine where the fault is, carry out detection records, and generate a static zero-power energy-saving charging power supply with charging protection function displayed by the data.

In order to solve the above technical problems, the utility model is realized by the following scheme: a static zero-power consumption energy-saving charging power supply with charging protection function, including a power interface, a power rectifier module, a charging protection module, and a charging interface.

The processing unit compares the preset information with the detection information, generates data, and then sends it to the display unit. The temperature comparison result is displayed through the display unit. The first The second alarm unit sends out a second alarm signal according to the temperature comparison result; the charging interface is connected to a corresponding electronic product.

Compared with the prior art, the beneficial effect is that the energy-saving control module can identify the load supplied by the power supply. As long as the load is connected, the energy-saving control module sends a control signal to the energy-saving switch module, and the energy-saving switch module is controlled according to the received control signal. When the power interface is connected, the power supply will automatically stop working after the load is removed to save power. It can detect the actual current and temperature of the equipment, accurately determine where the fault is, send an alarm signal in time, carry out detection records, and display the generated data, which is convenient. People check the charging status of the lithium battery to avoid unnecessary losses, safe and stable.
