Abstract

The invention provides a metering device, the device comprises a scale pan and an operation machine, wherein the operation machine comprises a display screen connected to a power supply, a control key group connected to the power supply and the display screen, a goods key group connected to the control key group, a number key group connected to the control key group and the goods key group, and the power supply. According to the invention, the power supply of the metering device has very high conversion efficiency, only 1-2 dry batteries can supply the electric power to the system, so that the volume and weight of an electronic scale are greatly reduced, and the portable design is realized.

Description

technical field [0001] The invention relates to the field of electronic appliances, in particular to a metering device. 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 a metering device 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 a metering device, which solves the problems of large volume and heavy weight of the existing metering device. [0005] Technical scheme of the present invention is realized like this: [0006] A metering device, c...
