[0032] In this embodiment, the utility model is specifically an electronic scale that dynamically displays a weight value QR code. When in use, the goods to be weighed are placed on the weighing pan 9 of the device, and the internal sensor 12 transmits the weighing data to the microprocessor. The microprocessor converts the weighing data into an electrical signal and transmits it to the encoder. The encoder generates the final QR code image from the electrical signal and displays it on the display screen 2. Customers can scan the QR code to obtain the weighing information using a PDA mobile phone or a barcode scanner.

A sensor platform 11 is arranged at the bottom position of the weighing plate 9, and a microprocessor is arranged at the bottom position of the sensor platform 11. A compiler is arranged at the rear side of the display screen 2, and the display screen 2 and the control component 3 are fixedly connected to the microprocessor.

[0034] Preferably, the electronic scale is turned on and adjusted to the standby mode through the adjustment button 4 in the control component 3. The sensor platform 11 arranged at the bottom of the weighing plate 9 transmits the weighing data to the microprocessor. The microprocessor converts the weighing data into an electrical signal and transmits it to the encoder. The encoder generates the final QR code image from the electrical signal and displays it on the display screen 2.

The support member 14 is connected to the sensor cavity 12 to support the upper weighing pan 9. The positioning member 15 is connected to the positioning cavity 13 to prevent the upper weighing pan 9 from rotating and affecting the weighing result. At the same time, the internal sensor 16 measures the pressure or force applied by the object on the scale and converts it into electrical signals. These electrical signals are sent to the internal microprocessor for digital processing. The outer support ring 10 ensures that the device is stable during weighing, prevents one side of the weighing pan 9 from tilting and damaging the internal sensor 16, and provides more accurate and faster weighing results.
