Abstract

The invention provides an electronic weighing instrument comprising a scale tray and an operating machine. The operating machine comprises a display screen which is connected with a power supply; a control key group which is connected with the power supply and the display screen; an object key group which is connected with the control key group; a number key group which is connected with the control key group and the object key group; and the power supply. With application of the electronic weighing instrument, the power supply has extremely high conversion efficiency and can realize power supply to the system by only 1-2 dry batteries so that the size and the weight of the electronic weighing instrument can be greatly reduced and the portable design can be realized.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to an electronic weighing instrument. Background technique [0002] Electronic scales can be seen everywhere in people's daily life. For example, electronic scales are required to weigh items in supermarkets, fruit stores and other places. In these places, there are various kinds of articles, and the existing electronic scales are large in volume and weigh 2-3 kilograms. The volume and weight are mainly occupied by batteries, and 4-6 batteries are often needed to meet the power supply needs. [0003] How to provide an electronic scale with a small battery size and energy saving is an urgent problem to be solved at present. Contents of the invention [0004] The invention provides an electronic weighing instrument, which solves the problems of large volume and heavy weight of the existing electronic weighing instrument. [0005] Technical scheme of the present invention is rea...
