Description
Affiliated technical field
The utility model relates to counter, a kind of counter that can the display power supply electric weight of more specifically saying so.
Background technology
The counter that tradition is known is not because the user knows in use how many electricity the inside has, and can run into the situation that does not have electricity suddenly, brings many inconvenience to the user.
Summary of the invention
The purpose of this utility model provides a kind of counter of energy display power supply electric weight, thereby allows the user know the service time of counter, has avoided in use running into the trouble that does not have electricity suddenly.
The purpose of this utility model can realize in the following manner: show the counter of electric weight, the liquid crystal display piece of display power supply electric weight is installed in the counter the inside.
The beneficial effects of the utility model are: by reminding what of electric weight, thereby allow the user know the service time of counter, avoid running in use the situation that does not have electricity suddenly.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is circuit diagrams of the present utility model
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail:
Referring to accompanying drawing 2, liquid crystal display piece 1 is in parallel with liquid crystal display piece 2, the voltage that is added in their two ends is the same, when electric weight was enough, displaying block 2 full lattice showed, when voltage descends, the lattice number that displaying block 2 shows reduces, if the lattice number has only lattice even when not had, then point out voltage not much of that soon, promptly power supply has exhausted soon.
