The loss of weight information output unit is connected with described central microprocessor, with the loss of weight information and the output of current weight information of described central microprocessor; And

The power circuit that is connected with described LOAD CELLS, described central microprocessor, described loss of weight information output unit.

In the utility model, central microprocessor in the electronic scales is to asking the output of difference back from the current weight weight of weighing of LOAD CELLS and the weight weight of weighing last time, thereby the subtrahend of realizing electronic scales is weighed or tired subtracting weighed, and whole electronic scales is simple in structure, easy to use, be beneficial to and apply.

Description of drawings

But subtrahend that Fig. 1 is the utility model to be provided or the tired internal module connection diagram that subtracts electronic scales.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Among the utility model embodiment, electronic scales is asked difference output to the current weight weight of weighing and the weight weight of weighing last time, thereby the subtrahend of realizing electronic scales is weighed or tired subtracting weighed.

But Fig. 1 shows subtrahend or the tired inside theory structure that subtracts electronic scales that the utility model provides, for convenience of description, only shows the part relevant with the utility model.

Electronic scales comprises base, the scale pan, scale pan support, the LOAD CELLS 11 that is connected with scale pan support is connected with central microprocessor 14, LOAD CELLS 11 is obtained weight of heavy and is converted into a weight signal, 12 pairs of these weight signals of amplifier carry out processing and amplifying, central microprocessor 14 is according to the weight signal of weight signal that obtained last time and current acquisition, with the current weight weight of weight weight subduction last time, the current loss of weight information of electron gain scale with respect to last time, and export this loss of weight information to loss of weight information output unit 15, by loss of weight information output unit 15 loss of weight information is exported, wherein central microprocessor 14 also can comprise a storer, is used to store loss of weight information.Between LOAD CELLS 11 and central microprocessor 14, also can connect an amplifier 12, be used for the weight signal of LOAD CELLS 11 is carried out processing and amplifying to satisfy the needs of central microprocessor 14, if having the function of A/D conversion, then can directly handle central microprocessor 14 weight signal, if central microprocessor 14 does not have the A/D translation function, then between amplifier 12 and central microprocessor 14, also connect an A/D converter 13, wherein electronic scales also comprises a power circuit (not shown), with LOAD CELLS 11, amplifier 12, A/D converter 13, central microprocessor 14, loss of weight information output unit 15 connects, for above-mentioned each unit provides electric energy.Further, loss of weight information output unit 15 comprises a voice module 151 that is connected with central microprocessor 14, to change the data of speech form from the loss of weight information of central microprocessor 14 into, by loudspeaker 152 outputs that are connected with voice module 151, as: loss of weight XX gram etc., thereby can report the weight of loss of weight behind each loss of weight automatically, wherein loudspeaker 152 can be installed on the front side of base.

Further, loss of weight information output unit 15 also comprises a display module 153, and it is connected with central microprocessor 14, will show output from the loss of weight information and the current weight information of central microprocessor 14, and wherein display module 14 can be installed on the front side of base.
