The beneficial effects of the utility model are: by the prompting electric weight what, avoid running in use the situation that does not have electricity suddenly.
Description of drawings
Figure one is the utility model flashlight schematic diagram
Figure two is the utility model flashlight liquid crystal display piece circuit diagrams.
Wherein, Reference numeral is as follows:
1, power supply 2, switch 3, liquid crystal display piece 4, pocket lamp bulb
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is described in further detail:
Referring to Fig. 1, liquid crystal display piece 3 is installed in the surface of flashlight, so that observe.
Referring to Fig. 2, liquid crystal display piece 3 is in parallel with pocket lamp bulb, the voltage that is added in their two ends is the same, when electric weight was enough, the full lattice of displaying block showed, when voltage descends, the lattice number that displaying block shows reduces, if the lattice number has only lattice even when not had, then point out the voltage block of bulb side not much of that, promptly power supply has exhausted soon.
