(5) embodiment:
Extremely shown in Figure 9 as Fig. 1, a kind of inflatable electronic scale of the present invention, comprise scale body 1, pressure transducer 12 and electronic scales control circuit, the electronic scales control circuit comprises metering circuit, central control unit and display 3, described scale body 1 is the inflation body of built-in enclosed air chamber 13, pressure transducer 12 is installed in the outer or air chamber 13 of air chamber 13, air pressure in the pressure transducer 12 induction air chambers 13 also utilizes metering circuit to convert electric signal to be input to central control unit, the central control unit computing and handle after the weight data that obtains is shown by display 3.Air chamber 13 the insides of scale body 1 are provided with some the drawstrings 14 that connect end faces 101 and bottom surface 103, and drawstring 14 makes scale body 1 inflation rear top surface 101 and bottom surface 103 more flat.Scale body 1 is provided with gusset band 102, and the top of shroud 102 is connected with bottom surface 103 with end face 101 respectively with bottom margin and seals.Central control unit is carried on the wiring board 4, and wiring board 4 and display 3 are installed on the housing 2.Metering circuit also is arranged on the wiring board 4.Housing 2 is connected with scale body 1 by two conduits 8,9.One of them conduit 8 is to be communicated with the air chamber 13 of scale body 1 the inside, and air pump 6 is set on housing 2, and air pump 6 is communicated with an end of conduit 8.Setting pressure sensor 12 on another conduit 9, pressure transducer 12 is connected with wiring board 4 by lead-in wire.Two installation feet 11 are set on the housing 2, a contact-making switch 7 that is used for energized is set on the installation foot 11.Disappointing gas is set on the scale body 1 chews, on the conduit 8 retaining valve can be set, leak in the time of can preventing to inflate.
A kind of electronic scales is measured the method for weight, and it is made of following steps: A) scale body 1 is inflated, measured the air pressure P1 of sealed gas chamber 13 in the scale body 1 by pressure transducer 12 and metering circuit; When B) article being placed on the scale body 1, measure the air pressure P2 of sealed gas chamber 13 in the scale body 1 by pressure transducer 12 and metering circuit; C) central control unit according to after not putting the air pressure P1 before the object and placing object air pressure P2 obtain draught head P0, calculate weight of object, and deliver to display 3 and show readings.
Principle of work of the present invention is: during work, scale body 1 is launched, thereby two installation feet 11 on the housing 2 are pressed closed contact-making switch 7 energized, 6 work of electronic scales control circuit control air pump, begin scale body 1 inflation, after the air pressure of the airtight air chamber 13 of scale body 1 the inside reached certain value, pressure transducer 12 and metering circuit passed the signal to electronic scales control circuit control air pump 6 and quit work, on the conduit 8 retaining valve is set, therefore can produce gas leakage.When object being placed on the scale body 1, because the object action of gravity is compressed air chamber 13, thereby cause air pressure to raise, pressure transducer 12 and metering circuit are sent to the electronic scales control circuit with measuring-signal, the electronic scales control circuit according to after not putting the air pressure P1 before the object and placing object air pressure P2 calculate weight of object, and deliver to display 3 and show readings.After using up, can open the gas that loses heart on the scale body 1 and chew the air of air chamber 13 is emitted, roll collection then.The present invention can shrink be convenient to the collection, light and be convenient for carrying, cost is low and interesting strong, simple in structure novelty.
