Detailed description of the invention
See Fig. 1, Fig. 2, a kind of weighing instrument, including pedestal 2, weighing unit 1, pressure transducer 6 and weigh circuit board 3,
Pedestal 2 is provided with accommodation space, and pressure transducer 6 electrically connects with weighing circuit board 3, also includes rechargeable battery 5 and wireless charging
Device 4, rechargeable battery 5, wireless charging device 4, weigh circuit board 3 be respectively positioned in accommodation space, rechargeable battery 5 is respectively with wireless
Charging device 4 electrically connects, weigh circuit board 3 electrically connects.
The technical program uses wireless charging device 4 to be powered rechargeable battery 5, when rechargeable battery 5 electricity of weighing instrument
During power deficiency, can use wireless charging device 4 that rechargeable battery 5 is charged, easy to use.For convenience of observing weight of weighing
Amount, weighing instrument can be provided with display screen 7 or machinery instrument；In the present embodiment, use the mode of display screen 7, pedestal 2 is arranged
Display screen 7, display screen 7 electrically connects with weighing circuit board 3.Wireless charging device 4 is prior art.
Further, also including pressure switch, pressure switch is arranged at below weighing unit 1 and is electrically connected with weighing circuit board 3
Connect.
The most a lot of weighing instruments uses key switch, and key switch in use, often forgets about closedown, thus leads
Cause battery electric power is wasted；After arranging pressure switch, so that weighing instrument after a procedure, disconnects automatically.Preferably, pressure is opened
Pass is arranged at below pressure transducer 6.
Seeing Fig. 3, further, pressure switch includes two contacts 61, being provided with contact 62 and bullet between two contacts 61
Spring 63；The two ends of spring 63 are connected with contact 62 and pedestal 2 respectively.
Further, weighing circuit board 3 and be provided with signal amplification circuit 9 and processor 10, weighing instrument also includes display screen 7,
Signal amplification circuit 9 electrically connects with pressure transducer 6, processor 10 respectively with signal amplification circuit 9, rechargeable battery 5 and aobvious
Display screen 7 electrically connects.
Operationally, pressure transducer 6 is used for sensing weight, and is digital signal by the analog-signal transitions of weight and passes
Passing signal amplification circuit 9 to be amplified, be then transferred to processor 10, the digital signal of weight is analyzed by processor 10
Process, and be transferred to display screen 7 and show.So that observing.Processor 10 can be MCU, single-chip microcomputer and control IC etc..
Further, also include that sound circuit 11, sound circuit 11 are connected with processor 10 signal.
After arranging sound circuit 11, when weighing, weight signal is sent to sound circuit 11 and reports by processor 10.
To be convenient for people to obtain.
Yet further, weighing instrument also includes storing device 12, and storage device 12 is connected with processor 10 signal.
When weighing, it may be possible to some article arranged are weighed, it is therefore desirable to record.If weighed once, record
Once, then work efficiency is affected.After storage device 12 is set, can store with weighing data.Without record repeatedly.Carry
High workload efficiency.Storage device 12 can be flash memory etc..
Above-described embodiment of the present utility model is only for clearly demonstrating this utility model example, and is not
Restriction to embodiment of the present utility model.For those of ordinary skill in the field, on the basis of described above
On can also make other changes in different forms.Here without also cannot all of embodiment be given exhaustive.
All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, should be included in this reality
Within novel scope of the claims.
