Abstract
The utility model provides an electronic scale with a film covering membrane type inductive switch, which comprises an inductive touch panel, a bottom cover matched with the inductive touch panel, a circuit board arranged between the inductive touch panel and the bottom cover, two electric conducting media and two electric conductors, wherein the two electric conducting media are printed on one side of the inductive touch panel; and one end of each electric conductor in the two electric conductors is connected with one electric conducting medium, and the other end of each electric conductor is connected with the circuit board. Therefore, the uniformity of the sensitivity is kept, the occurrence of false operation is prevented, and the cost is also reduced.
Description
Technical field
The utility model relates to a kind of electronic scales, relates in particular to a kind of electronic scales that has the film covering type inductive switch.
Background technology
At present, the normal electronic scales that uses comprises an induction type touch panel, is covered on a bottom of described induction type touch panel top, is arranged on the main circuit board between described bottom and the described induction type touch panel, an and little circuit board that is fitted in described induction type touch panel lower surface, described little circuit board is fitted in after the described induction type touch panel below, can directly hand be placed on described induction type touch panel top and respond to, make numeral to occur on the display screen of electronic scales.Yet, because this electronic scales has used described main circuit board and two circuit boards of described little circuit board, so the cost height; In addition, because described little circuit board is fitted in described induction type touch panel below, if described little circuit one end warpage or flexural deformation, it is bad then to make described little circuit board fit easily, thereby makes that this electronic scales is insensitive, causes misoperation easily.
Therefore, be necessary to design a kind of new electronic scales, to improve above-mentioned defective.
The utility model content
Thereby the purpose of this utility model provides a kind of electronic scales that has the film covering type inductive switch that relative environment is consistent keep the sensitivity unanimity.
The purpose of this utility model is achieved through the following technical solutions: a kind of film covering type inductive switch comprises: two conducting mediums are printed on a side of an induction type touch panel.
A kind of electronic scales, comprise an induction type touch panel, a bottom that cooperates with described induction type touch panel and be arranged at a circuit board between described induction type touch panel and the described bottom, further comprise two conducting mediums and two electric conductors, described two conducting mediums are printed on a side of described induction type touch panel, each described electric conductor one end connects a described conducting medium in described two electric conductors, and the other end connects described circuit board.
The electronic scales that the utility model has the film covering type inductive switch has following advantage:
(1) because two conducting mediums are printed on a side of an induction type touch panel, is consistent with the relative environment of described two conducting mediums, thereby keeps the sensitivity unanimity, prevent that misoperation from occurring so can guarantee described induction type touch panel.
(2) owing to print two conducting mediums, only use a circuit board, so provide cost savings in a side of an induction type touch panel.
Description of drawings
Fig. 1 has the partial schematic diagram of the electronic scales of film covering type inductive switch for the utility model.
The implication of each Reference numeral sees the following form among the figure:
Embodiment
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
As shown in Figure 1, the utility model has the electronic scales of film covering type inductive switch, comprises an induction type touch panel 1, a bottom (not shown) that cooperates with described induction type touch panel 1, is arranged at a circuit board 2, two conducting mediums 3, two electric conductors 4 and two leads 5 between described induction type touch panel 1 and the described bottom.Fig. 1 only shows a conducting medium 3 one electric conductors and a lead 5.
Described induction type touch panel 1 is made by glass or plastics.The side that described two conducting mediums 3 are printed on described induction type touch panel 1 is a lower surface 11.Each described electric conductor 4 electrically connects a described conducting medium 3 to described circuit board 2 in described two electric conductors 4.
Described two conducting mediums 3 are conductive carbon or conductive silver paste.Described conductive carbon comprises graphite and printing ink.Described conductive silver paste comprises silver powder and printing ink.Described electric conductor 4 is spring or electric silica gel.Described spring one end is welded with described lead 5, and the end that described spring connects described lead 5 connects described conducting medium 3, and described lead 5 is connected to described circuit board 2.During use, directly touch the position that described induction type touch panel 1 correspondence is provided with described two conducting mediums 3, promptly relative with described lower surface 11 upper surface 12 can make that the display screen 13 on the described induction type touch panel 1 demonstrates numeral.
Because described two conducting mediums 3 are printed on the lower surface of described induction type touch panel 1, be consistent with described two conducting mediums, 3 relative environment so can guarantee described induction type touch panel 1, thereby keep the sensitivity unanimity, prevent that misoperation from occurring.And owing to only use a described circuit board 2, so provide cost savings.
To sum up, the utility model electronic scales of having a film covering type inductive switch has following advantage:
(1) because two conducting mediums are printed on a side of an induction type touch panel, is consistent with the relative environment of described two conducting mediums, thereby keeps the sensitivity unanimity, prevent that misoperation from occurring so can guarantee described induction type touch panel.
(2) owing to print two conducting mediums, only use a circuit board, so provide cost savings in a side of an induction type touch panel.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
