Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, an automatic power-off charging device for mobile phone temperature rise over-limit comprises a circuit system and peripheral equipment; the peripheral comprises a power line 1, a metal supporting plate 2 and a plastic box 3; the circuit system is positioned in the plastic box 3 and comprises a power supply module, a control circuit and a relay; a first power socket 4, a second power socket 5, an indicator light 6 and a buzzer 7 are arranged on the shell of the plastic box 3; the end part of the power line 1 is provided with a three-phase plug, the grounding contacts of the first power socket 4 and the second power socket 5 are connected with the ground wire inside the power line 1 through wires, the zero line contact is in short circuit with each other and is connected with the ground wire inside the power line 1, and the live wire contact is in short circuit with each other and is connected with a normally open output end of the relay; the other normally open output end of the relay is connected with a live wire of the power line 1; the input end of the power supply module is connected between the live wire and the zero line of the power supply line 1; the output end of the power supply module supplies power to the control circuit; the input end of the control circuit is connected with the temperature sensor; three output ends of the control circuit are respectively connected with the buzzer 7, the indicator lamp 6 and the relay control end.
The metal supporting plate 2 is made of stainless steel, and the ground wire of the power line 1 is in short circuit with the metal supporting plate 2.
The temperature sensor is arranged on the metal supporting plate 2.
As shown in fig. 1, a power line 1 is plugged, and a power module converts 220V alternating current into low-voltage direct current; providing direct current electric energy for the control circuit, and starting the control circuit to work; the output end of the control circuit controls the normally open contact of the relay to be closed; the first power outlet 4 and the second power outlet 5 are connected to an external power source. The output end of the control circuit also controls the indicator lamp to be turned off; and controlling the buzzer to mute.
