An electronic scale is a kind of weighing apparatus, and is a tool for measuring the mass of objects based on the Hooke's law or the lever balance principle of force. An electronic scale is mainly composed of three parts: a weight bearing system (such as a scale plate or a scale body), a force transfer and conversion system (such as a lever force transfer system or a sensor), and a value display system (such as a dial or an electronic display instrument). According to the structure principle, there are mechanical scales, electronic scales and electromechanical scales. At present, the electronic scale products are developing towards the direction of smart home products, and the function of the products is not limited to weighing. The existing electronic scales are very similar in model andbasically adopt an immutable shape, and occupy large space in a room. In order to meet the needs of more convenient storage and space saving, we hope to design a handheld electronic scale. When the handle of the electronic scale is held by a hand, an object is lifted, and the weight of the object is displayed on the display screen.
