Problems solved by technology

[0002] With the improvement of people's living standards, electronic products are gradually popularized, and weighing tools have developed from the previous steelyards, case scales, scales, etc., which require manual reading to today's digital display type. However, in daily life, people often need to weigh Lighter objects, such as weighing dry goods, etc., or when buying vegetables or fruits, can also prevent small vendors from being short of catties. Because general weighing tools are too bulky to carry around, they cannot meet such needs

Abstract

The invention discloses a power management system of an electronic scale. The power management system includes a charging port 1, a charging management IC 2, a built-in charge battery 3, an electronic scale single-chip microprocessor circuit 4 and a display unit 5. The electronic scale single-chip microprocessor circuit 4 is also connected with a key unit 7 and a weight sensing module 8. An external power source charges the built-in charge battery through a charging port which is a USB interface. The invention also provides the electronic scale. According to the invention, by designing the electronic scale which is small in size and compact in structure and by connecting a weight sensing piece between a handle and a hook, a user can read the weight of an object directly through a display screen. At the same time, the electronic scale has the USB charging port, so that the electronic scale can be charged quickly by using a computer, a portable power source, a USB wire and the like after the battery runs out. Compared with a regular dry battery, the battery of electronic scale is long in working duration and long in cyclic use life and is also more economic, practical and environment friendly.

Description

technical field [0001] The invention relates to an electronic scale, in particular to a power management system of the electronic scale and the electronic scale. Background technique [0002] With the improvement of people's living standards, electronic products are gradually popularized, and weighing tools have developed from the previous steelyards, case scales, scales, etc., which require manual reading to today's digital display type. However, in daily life, people often need to weigh Lighter objects, such as weighing dry goods, or buying vegetables or fruits can also prevent small vendors from being short of catties. Because general weighing tools are too bulky to carry around, they cannot meet such needs. Contents of the invention [0003] In view of the deficiencies in the prior art, the invention provides a small, portable electronic scale and a power management system for the electronic scale. [0004] In order to achieve the above object, the present invention a...
