Abstract
Present invention design discloses a kind of mini formula electronic scale, mainly by support object iron plate, spring (two), slide rheostat, fixed value resistance, ammeter, switch, power supply, conducting wire composition.Wherein, the support object iron plate is connected with slide rheostat；Spring is connected in support object iron plate both sides；Ammeter is connected with slide rheostat；Fixed value resistance is connected with slide rheostat；Switch is connected with power supply；Rest part is connected again with conducting wire.In this way, just constitute a kind of novel simple self-control electronic scale.When the weight of object to be weighed, first closure switch；Not during weighing object, slide rheostat resistance value is very big, electric current very little on ammeter；When there is weight to be placed on support object iron plate, under pressure, it can change the resistance value of slide rheostat, so that electric current becomes larger；By the changing value of electric current, it just can easily know the quality of weight, so not only facilitate but also quick, and accuracy is high, lives to people highly advantageous.
Description
Technical field
Present invention design is a kind of electronic scale, especially designs a kind of mini formula electronic scale.
Background technology
With the development of society, people’s lives level is not continuously improved, people’s lives mode is also changing, Ren Menxi
The problem of hoping in life can more efficiently solve, it is desirable to do things more efficient.Electronic scale is higher and higher in the status of life, people
Live in be required for using electronic scale everywhere, but electronic scale currently on the market is not only heavy, and accuracy is not high, often
People is allowed to complain.In order to adapt to the development in market, I thinks that it is necessary to invent a kind of more accurate, convenient electronic scale, Ke Yigeng
Good is that people solve problem concerning life.
The content of the invention
Present invention design is problem to solve is that provide a kind of mini formula electronic scale.Its production method is simple, valency
Lattice are very cheap, use also easily, offer convenience for life at home.
For solution more than technical problem, the technical solution that the present invention designs is as follows：
A kind of mini formula electronic scale, mainly by support object iron plate, spring (two), slide rheostat, fixed value resistance, electric current
Table, switch, power supply, conducting wire are formed.Wherein, the support object iron plate is connected with slide rheostat；Spring is connected in support object iron plate both sides；
Ammeter is connected with slide rheostat；Fixed value resistance is connected with slide rheostat；Switch is connected with power supply；Rest part is again with leading
Line connects.Thus constitute a kind of mini formula electronic scale.
The advantageous effect that the present invention designs is：Simple in structure, easy to make, at low cost, when use, is simple to operate, is
Life offers convenience at home.
Description of the drawings
Attached drawing is the design principle schematic diagram of a mini formula electronic scale.
Specific embodiment
Present invention design is described further with reference to the accompanying drawings and examples：
As shown in drawings, present invention design is mainly by 1 support object iron plate, 2,3 springs (two), 4 slide rheostats, 5 definite values
Resistance, 6 ammeters, 7 switches, 8 power supplys, 9 conducting wires are formed.Wherein, the 1 support object iron plate is connected with 4 slide rheostats；2,3 bullets
Spring is connected in 1 support object iron plate both sides；6 ammeters are connected with 4 slide rheostats；5 fixed value resistances are connected with 4 slide rheostats；7 switches
It is connected with 8 power supplys；Rest part is connected again with 9 conducting wires.In this way, just constitute a kind of mini formula electronic scale.
Present invention design so uses：
When the weight of object to be weighed, first closure switch；Not during weighing object, slide rheostat resistance value is very big, ammeter
Upper electric current very little；When there is weight to be placed on support object iron plate, it under pressure, can change the resistance value of slide rheostat, from
And electric current is made to become larger；By the changing value of electric current, it just can easily know the quality of weight, so not only facilitate but also quick, and
Accuracy is high, lives to people highly advantageous.
