Battery with indication function

Abstract

The invention discloses a battery with an indication function. The battery comprises a housing, a negative plate, an electrolyte, a cell and a positive electrode terminal. The interior of the housingis divided into two cavities through a liquid sealing plate. The electrolyte is located in the cavity close to one side of the negative plate, and a transversely arranged conductive spring is arrangedin the other cavity. One end of the conductive spring makes contact with the cell, and the other end of the conductive spring is connected with a transversely arranged positive pole, wherein the positive pole is of a hollow structure, and the positive pole is connected with the positive electrode terminal through the transversely arranged spring. The positive electrode terminal is inserted into the positive pole and is in sliding connection with the positive pole. A conductive layer is arranged on the inner wall of the positive pole, a conductive sliding block is fixedly connected to the sidewall of the outer side of the positive electrode terminal, and the conductive sliding block makes contact with the conductive layer. According to the invention, the battery with the indication function can achieve the accurate indication of the use amount of the battery, and can effectively avoid an electric leakage phenomenon when the battery is not used.

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
