Self-powered fat-measuring weight scale

Abstract

The invention relates to a self-powered fat-measuring weight scale. The self-powered fat-measuring weight scale comprises an electronic scale and a display screen. The self-powered fat-measuring weight scale is characterized in that the self-powered fat-measuring weight scale further comprises a base a, a base b, a linkage device, a slider and linkage rods; the electronic scale is fixedly connected to the upper side of the base a; a square slot is formed in the middle of the electronic scale; the display screen is fixedly connected to the upper part of the square slot and is connected with theelectronic scale; the slider is disposed in the square slot and is located below the display screen; two sides of the slider are connected with one end of one linkage rod and one end of the other linkage rod respectively through shafts; the other end of each linkage rod is connected with one end of a corresponding spiral spring; the other ends of the spiral springs are connected with fat-measuring sticks; the base b is located below the base a; and the base a and the base b are connected by the linkage device. An existing weight scale needs the power supply of a dry battery, and as a result,the problems of resource waste and environmental pollution may be brought about, while, with the self-powered fat-measuring weight scale of the invention adopted, the above problems can be solved. Theweight scale of the invention has a fat-measuring function.

Description

technical field [0001] The invention relates to the field of electronic scales, in particular to the field of self-generating weighing scales. Background technique [0002] The weight scale is mainly composed of three parts: load-bearing system, force transmission conversion system and display system. It is an electronic weighing device integrating modern sensor technology, electronic technology and computer technology. [0003] Most of the existing weight scales are based on the principle that when an object is placed on the weighing pan, pressure is applied to the sensor, and the sensor undergoes elastic deformation, thereby changing the impedance, and at the same time using the excitation voltage to change, outputting a changed analog signal; the signal After being amplified by the amplifier circuit, it is amplified and output to the analog-to-digital converter; it is converted into a digital signal that is easy to process and output to the CPU operation control, and the ...

Problems solved by technology

[0003] Most of the existing weight scales are based on the principle that when an object is placed on the weighing pan, pressure is applied to the sensor, and the sensor undergoes elastic deformation, thereby changing the impedance, and at the same time using the excitation voltage to change, outputting a changed analog signal; the signal After being amplified by the amplifier circuit, it is amplified and output to the analog-to-digital converter; it is converted into a digital signal that is easy to process and output to the CPU operation control, and the CPU outputs the result to the display according to the received digital signal; all of this is inseparable from the continuous supply of electric energy. Most of the weighing scales in the prior art are dry batteries or need to be charged, which not only consumes energy but also may bring harm to the environment, and the existing weighing scales have a single function and can only be used to measure body weight
