A kind of battery with indication function

Abstract

The invention discloses a battery with an indicating function, which includes a casing, a negative plate, an electrolyte, a cell and a positive terminal. The casing is divided into two chambers by a liquid sealing plate, and the electrolyte is located close to the The chamber on one side of the negative plate, wherein the other chamber is provided with a horizontally arranged conductive spring, one end of the conductive spring is in contact with the battery core, and the other end of the conductive spring is connected to a horizontally arranged positive pole. The positive pole is a hollow structure, and the positive pole is connected to the positive end through a spring arranged laterally in the positive pole. The positive end is inserted in the positive pole and is slidably connected to it. A conductive layer is provided on the inner wall of the positive pole. A conductive slider is fixedly connected to the outer side wall of the positive terminal, and the conductive slider is in contact with the conductive layer. In the present invention, the battery with an indicating function can accurately indicate the battery usage, and can effectively avoid leakage when the battery is not in use.

Description

technical field [0001] The invention relates to the technical field of energy storage components, in particular to a battery with an indicating function. Background technique [0002] The battery is an energy storage element that is used in every household. It is small in size and easy to use. A small dry battery is used in remote controls, toys, etc. After understanding, it leads to inoperable situation during use. After searching the Chinese patent number: CN105591167B energy-concentrating indicating battery, by setting the indicating liquid in the battery, it can be an electrorheological fluid or an organic color-changing liquid. According to the usage of the power, the The state of the electrorheological fluid changes, and the color of the latter organic color-changing liquid changes to estimate the battery power, but the estimation accuracy is low; in addition, after searching the Chinese patent number: CN104701480B anti-leakage battery, the application document In thi...

[0002] The battery is an energy storage element that is used in every household. It is small in size and easy to use. A small dry battery is used in remote controls, toys, etc. After understanding, it leads to inoperable situation during use. After searching the Chinese patent number: CN105591167B energy-concentrating indicating battery, by setting the indicating liquid in the battery, it can be an electrorheological fluid or an organic color-changing liquid. According to the usage of the power, the The state of the electrorheological fluid changes, and the color of the latter organic color-changing liquid changes to estimate the battery power, but the estimation accuracy is low; in addition, after searching the Chinese patent number: CN104701480B anti-leakage battery, the application document In this method, a conductive liquid is set in the sealed cavity, and under the action of the gravity of the conductive liquid, the conductive liquid moves at both ends of the sealed cavity, so that when it moves to one end with a conductive contact piece, the battery is energized, and at the other end, it is realized. Power off, but because it is a conductive liquid, it will inevitably adhere to the inner wall of the sealed cavity when moving, and there is a possibility of conducting the battery
