A kind of fatty scale
[technical field]
This utility model relates to a kind of fatty scale.
[background technology]
The fat scale be a kind of employing be that human-body biological resistance is analyzed (Bioelectric Impedance Analysis) technology, its principle is body fluid, muscle of health simply being divided into conduction etc., and the poor fatty tissue of conduction, send atomic little electric current through health by electrode during measurement, if fat ratio is high, measured biologic resistance is larger, otherwise less.Due to fatty scale analytical calculation body fat rate fast and accurately, therefore substitute gradually traditional common scale with body weight and Stature estimation method.
Existing fatty scale is with the bridge of electrode as human body and measuring circuit, its performance quality directly has influence on the accuracy of measurement, yet electrode sticks on scale foundation, in use easily come off, the problem such as wearing and tearing, affect service life, accuracy and the speed of fat is measured in impact, and electrode affect the comfort that the user both feet contact when being located on the scale body or raised or sunken.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of simple in structure, long service life, and accuracy of measurement is high, measures fatty scale efficiently.
The purpose of this utility model is achieved in that
A kind of fatty scale, it is characterized in that it comprises base, the bottom of base is provided with a plurality of feets, be provided with sensing element in feet, described base is provided with display and control unit and face glass, described face glass is provided with at least one pair of for the conducting film, conducting film and the display and control unit conducting that are contacted respectively by the user both feet.
A kind of fatty scale as above is characterized in that described conducting film is nesa coating.
A kind of fatty scale as above is characterized in that described conducting film is strip, and this is symmetrically distributed in the arranged on left and right sides on face glass surface to conducting film.
A kind of fatty scale as above, it is characterized in that described base comprises the base head, the left and right two ends of the first side of base respectively are provided with a base leg, the tail end of these two base legs respectively is provided with a foot, feet is arranged on the bottom of base head and foot, and described display and control unit is arranged on the base head.
A kind of fatty scale as above is characterized in that described display and control unit comprises control circuit board and display.
This utility model is with the fatty scale design science of nesa coating, and is rational in infrastructure, and it overcomes existing like product scale surface because of the raised or sunken defective that installing electrodes causes, and has improved the comfort of testee's both feet contact in the use procedure.This nesa coating both can make the scale foundation surfacing, cracky not, and be arranged on organic being laminated with on transparent scale surface of ELD on transparent scale foundation surface, form a complete transparent scale, make the outward appearance of product and moulding exquisiter and attractive in appearance, and simple in structure, accuracy of measurement is high, measure fast conducting film difficult drop-off, long service life.

[specific embodiment]
A kind of fatty scale, it comprises base 1, the bottom of base 1 is provided with a plurality of feets 2, be provided with sensing element in feet 2, described base 1 is provided with display and control unit 3 and face glass 4, described face glass 4 is provided with at least one pair of for the conducting film 5 that is contacted respectively by the user both feet, conducting film 5 and display and control unit 3 conductings.Conducting film 5 is nesa coating, and described conducting film 5 is strip, and preferably left side upper/lower terminal is each three, each three of the right upper/lower terminals, and left and right both sides are symmetrically distributed in the arranged on left and right sides on face glass 4 surfaces.Operation principle of the present utility model is: after user stands on scale, the foot of user is connected the pair of conductive film at least, measure human body impedance, calculate body fat by display and control unit 3 according to body weight, human body resistance and the subscriber data (as height, age, sex etc.) measured again, and show, this utility model has overcome existing like product scale surface because of the raised or sunken defective that installing electrodes causes, and has improved the comfort of testee's both feet contact in the use procedure.This nesa coating both can make the scale foundation surfacing, cracky not, and be arranged on organic being laminated with on transparent scale surface of ELD on transparent scale foundation surface, and form a complete transparent scale, make the outward appearance of product and moulding exquisiter and attractive in appearance,
Base 1 comprises base head 101, the left and right two ends of base head 101 1 sides respectively are provided with a base leg 102, the tail end of these two base legs 102 respectively is provided with a foot 103, feet 2 is arranged on the bottom of base head 101 and foot 103, and described display and control unit 3 is arranged on base head 101.
Wherein base head 101 comprises again bottom 1011 and cover 1012.
Display and control unit 3 comprises phase control circuit board 31 and display 32 all, sensing element and conducting film 5 and control circuit board 31 conductings, also be provided with control knob assembly 104 on described base head 101, control knob assembly 104 and control circuit board 31 conductings.
