Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] figure 1 It is a common appearance schematic diagram of the electronic scale with self-power supply function of the present invention.

[0029] Such as figure 1 As shown, the electronic scale with self-power supply function of the present embodiment includes: a scale body 10, a measurement display unit 40 arranged in the scale body 10, and an energy storage device 50 ( figure 1 not shown) and power generation device 30. The scale body 10 includes an upper cover 2 and a bottom case 6 , and a surface case 1 may be provided on the upper cover 2 . The power generating device 30 includes: a transmission device 90 and a generator 31 . The operating part 96 of the power generating device 30 is located above the scale surface, and is used for the user to apply part of the gravity of the human body by stepping on the sole of the foot.

Abstract

The invention discloses an electronic scale with self-powered function, which comprises a scale body and a measurement display unit. The electronic scale is characterized in that the electronic scale also comprises an energy-storing device of the measurement display unit and a generating device for supplying electric energy to the energy-storing device; the generating device applies external force through human bodies, for example, pedals by use of feet or pushes by use of hands to drive a generator to generate electric energy; the generating device comprises a transmission device and the generator or a generation component in other forms; the transmission device changes small-stroke rectilinear or swinging motion into high-speed circular motion, and comprises gear transmission mechanisms from Grade 1 to Grade 10 moving along with human external force; a force-applying operation part of the transmission device is positioned above the weighing surface of the scale body or arranged around the scale body, or is an scale-body upper cover connected with the transmission device; and the energy-storing device comprises a capacitor for storing electricity, a storage battery or a rechargeable battery and other electricity-storing devices. The electronic scale has the advantages that: the electronic scale adopts the own generating device to supply power, thereby not only reducing use cost, but also avoiding producing waste batteries to pollute environment.

Description

technical field [0001] The invention relates to the field of electronic scales, in particular to an electronic scale with a self-power supply function which generates the working electric energy required by the electronic scale by itself by means of a mechanical structure inside the electronic scale while weighing. Background technique [0002] At present, the number of various electronic scales sold in the world is increasing every year. For example, the sales volume of global human health scales in 2006 is tens of millions, and all of them need to install batteries to work normally. Calculated only by the consumption of one dry battery per year by each human health scale, the number of waste batteries produced thereby is more than tens of millions. If the used batteries are not disposed of properly, or even discarded into the living environment without treatment, it will cause serious harm to the environment and human beings. The hazards of waste batteries are mainly conc...
