Micro electronic scale

Abstract

The invention relates to the field of electronic scales, in particular to a micro electronic scale which comprises an outer shell, anti-skid blocks, suckers, an inner shell, a weighing sensor, air holes, dustproof nets, a lithium battery, a single chip microcomputer, a Bluetooth transceiving module, an alarm lamp, a buzzer, a supporting seat, supporting rods, sleeves, sliding blocks, scale pans, aloudspeaker, sliding grooves, movable blocks, connecting rods and movable grooves. According to the invention, through the air holes and the dustproof nets in the air holes, internal heat dissipationof the outer shell is enhanced, and dust is prevented from entering; the single chip microcomputer controls the loudspeaker to sound to read out the weight of a weighed object; connection and transmission with a mobile phone are facilitated through the Bluetooth transceiving module; the single chip microcomputer controls flickering of the alarm lamp and sounding of the buzzer, so that the micro electronic scale is convenient to find; fixing and moving are convenient through the antiskid blocks and the suckers; and the two scale pans are separated, the scale pans slide through the sliding grooves and the sliding blocks at the top ends of the supporting rods, the scale pans slide through the movable grooves and the sliding blocks at the two ends of the connecting rods, the supporting rangeof the scale pans is adjusted, and use is convenient.

Description

technical field [0001] The invention relates to the field of electronic scales, in particular to a microelectronic scale. Background technique [0002] Electronic scale is a kind of weighing instrument, which is a tool to measure the quality of objects by using Hooke's law or the principle of lever balance of force. According to the structural principle, it can be divided into three categories: mechanical scale, electronic scale, and electromechanical combination scale. (such as weighing pan, scale body), force transmission conversion system (such as lever force transmission system, sensor) and display system (such as dial, electronic display instrument) consists of 3 parts. [0003] At present, the existing microelectronic scales make the load cells vulnerable to damage in harsh working environments, which easily reduces the weighing accuracy and service life, and the existing microelectronic scales do not protect the load cells, and the existing microelectronic scales Whe...

Problems solved by technology

[0003] At present, the existing microelectronic scales make the load cells vulnerable to damage in harsh working environments, which easily reduces the weighing accuracy and service life, and the existing microelectronic scales do not protect the load cells, and the existing microelectronic scales When weighing, the scale cannot adapt to weighing items of different volumes, which is inconvenient to use. The microelectronic scale is small in size, easy to lose, and difficult to find
