Anti-electric-leakage battery special for toy

Abstract

The invention discloses an anti-electric-leakage battery special for a toy. The anti-electric-leakage battery comprises a cylindrical casing, an inner core, a positive electrode and a negative electrode, wherein the inner core comprises a positive electrode material and a negative electrode material. The anti-electric-leakage battery is characterized in that a conductive plate is in sealed and fixed connection to the inner wall of the casing; the conductive plate separates the housing into a core cavity and a sealed cavity; the inner core is located inside the core cavity; and a conductive rodis electrically connected to a side of the conductive plate close to the negative electrode. The anti-electric-leakage battery has an advantage that after the toy is used, a coil is de-energized suchthat a magnetic field disappears and a magnetorheological fluid restores to a normal liquid phase property, at this time, a second piston moves away from a communicating pipe under the effect of a return spring to slowly pump the magnetorheological fluid in a middle cylinder back to a side cylinder, and a first piston in the middle cylinder also moves away from the conductive rod so that the battery cannot supply power to the outside, thereby avoiding the electric leakage of the toy caused by long-time standing.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a special anti-leakage battery for toys. Background technique [0002] In daily life, cylindrical batteries are the most widely used batteries, such as No. 5 batteries and No. 7 batteries; and such batteries are generally used for daily necessities such as remote controls and toys; and for electronic circuits, due to the gap between components The coupling is very tight, even if there is no output at the output end, a weak leakage current will be generated at the input end; since the working time of this kind of daily necessities is much shorter than the idle time, from a long-term perspective, this kind of leakage current will add up and will account for The relatively considerable proportion of the entire battery power leads to a significant reduction in the service life of the battery; for this reason, in the actual use process, some users will put the positive and negative poles of t...

AI Technical Summary

Problems solved by technology

[0004] After analysis, although the above-mentioned prior art can solve the phenomenon that the battery does not leak electricity when the electrical appliance is not in use, it cannot be well applied to toys. The toy may run at various angles for a certain period of time during use, and may be reused at any time. In the prior art, the user needs to twist the battery to reach a certain angle to ensure the normal use of the battery and power off, while the toy uses During the process, it may be deflected to the power-off angle, so that the battery in the prior art cannot provide a better user experience
