Abstract

The invention discloses an electronic scale with a self-generation system. The electronic scale comprises a scale body, an LCD (Liquid Crystal Display) display, a sensor, a master control circuit board, an electric energy storage system and the self-generation system, wherein the LCD display and the sensor are arranged on the scale body; the output end of the self-generation system is connected with the electric energy storage system to realize electric energy storage; and the electric energy storage system is connected with the master control circuit. The design of the self-generation systemis added on the basis of the traditional electronic scale, the electronic scale with the self-generation system can work normally without depending on external power supply or batteries, and a user provides electric energy required by the electronic scale only by the self-generation system, thus the electronic scale is more commendable at present nowadays with growing energy shortage. Furthermore, the electronic scale has the advantages of convenience for use, environmental protection and the like.

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 ...
