[0024] Example

[0025] See also Figure 1-3 , the utility model provides a technical solution:

[0026] A screwdriver with a heating function, wherein a screwdriver rod 2 is installed below the main body 1, a screwdriver head 3 is installed below the screwdriver rod 2, a screwdriver tip 4 is installed below the screwdriver head 3, a repair interface 5 is installed at the rear of the main body 1, a temperature sensor 6 is installed inside the main body 1, a heating wire 7 is installed inside the main body 1, a current sensor 8 is installed inside the main body 1, a relay 9 is installed inside the main body 1, a resistor 10 is installed inside the main body 1, and an LED lamp bead 11 is installed below the main body 1.

[0027] In this embodiment, first, the heating wire is the core component of the device. The heating wire converts electrical energy into thermal energy by means of resistance heating. When power is supplied to the heating wire, the resistance of the heating wire generates heat, causing it to heat up. By controlling the current and power supply time of the heating wire, the heating control of the device can be achieved. The temperature sensor is a component used to measure the surface temperature of the device. It can monitor the temperature changes on the surface of the device in real time and transmit these data to the control system. By comparing with the set target temperature, the control system can determine whether it is necessary to continue heating or stop heating. The current sensor is used to monitor the current changes of the heating wire. It can measure the current size of the heating wire in real time and transmit these data to the control system. By monitoring the current, the control system can understand the working state of the heating wire and make corresponding control decisions as needed. The relay is an electrical switch device used to control the on and off of the power supply. When the control system determines that heating is required, the relay will turn on the power supply to start heating the heating wire. Conversely, when the control system determines that heating is no longer required, the relay will cut off the power supply and stop heating the heating wire. LED lamp beads can be used as status indicators. Through the control of relays and switch circuits, the LED lamp beads can be turned on and off according to the working status of the equipment, providing visual information. The switch circuit plays the role of connecting and disconnecting the circuit. It is connected to the relay and can control the on and off of the LED lamp beads and the control of the power supply by the relay. The device is equipped with the SL-AI31□-A□5N single-phase AC current isolation transmitter of the Shangliang brand. The input range of the device is 0.1A~10A, the product accuracy is 0.5 level, the output signal is 0-5Vac, and the auxiliary power supply is +12Vdc, +15Vdc, +24Vdc, 220Vac.
