Abstract
Description
technical field
[0001] The invention relates to a weighing device, in particular to an electronic scale equipped with a self-generating system. Background technique
[0002] Electronic scale is a common weighing device in daily life. Because of its simple operation and intuitive display, it is widely used. The existing electronic scale mainly includes the main body of the scale, display device, sensor and other components, and needs to be powered by an external power supply or battery. Power supply, at present, there are two main power supply methods for existing electronic scales: one is battery power supply; the other is solar power supply. Battery power supply is the most common way, but the service life of the battery is short, there are problems such as self-discharge and environmental pollution; although solar energy has the advantages of environmental protection, its high cost, low efficiency and high dependence on the surrounding environment cannot meet the needs of ...
