Storage battery for electric tool for garden and automatic injecting device for electrolyte of storage battery

Abstract

The invention discloses a storage battery for an electric tool for a garden and an automatic injecting device for electrolyte of a storage battery. The storage battery comprises an electrolyte storing tank, a liquid delivery pipe, a peristaltic pump, an electrolyte adding cap, a vent cap and a storage battery body, wherein the storage battery body consists of an ABS (Acrylonitrile Butadiene Styrene) casing, a top cover, a positive terminal, a negative terminal, AGM separators, positive plates and negative plates; the bottom end of the positive terminal is connected with the positive plates; the bottom end of the negative terminal is connected with the negative plates; electrode lug connecting slots of which openings face upwards are separately formed inside the positive terminal and the negative terminal; the inner part of the electrode plug connecting slot of the positive terminal is in threaded connection with a positive electrode plug; the inner part of the electrode plug connecting slot of the negative terminal is in threaded connection with a negative electrode plug. Assembly and disassembly of the positive electrode lug and the negative electrode lug, injection of the electrolyte, and exhaust of air are facilitated; by means of the peristaltic pump, the electrolyte in the electrolyte storing tank is conveniently extruded forwards by the liquid delivery pipe in the rotating direction of a center wheel, and corrosion caused by contact between the electrolyte in the liquid delivery pipe and the peristaltic pump is also effectively avoided; quantitative injecting of the electrolyte is realized.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a storage battery for garden electric tools and an automatic electrolyte filling device thereof. Background technique [0002] Batteries are widely used in garden power tools, because they can store electrical energy as chemical energy when charging, and can effectively convert chemical energy into electrical energy when discharging, and have a large storage capacity and are easy to carry. Therefore, they are widely used in garden power tools It does not need the traditional external power cord to affect its mobile flexibility and difficult wiring. [0003] Existing batteries are usually packaged in the shell with clean positive plates, negative plates and electrolytes. Not only positive poles, negative poles and safety valves must be set on the battery cover, but also multiple electrolyte filling ports should be opened. During production, the electrolyte is filled into the ba...

AI Technical Summary

Problems solved by technology

[0003] Existing batteries are usually packaged in the shell with clean positive plates, negative plates and electrolytes. Not only positive poles, negative poles and safety valves must be set on the battery cover, but also multiple electrolyte filling ports should be opened. During production, the electrolyte is filled into the battery through the electrolyte filling port, but an additional cover is required to seal the electrolyte filling port

When the battery moves or shakes, once the cover is shaken off, the electrolyte will flow out, and only the electrolyte filling port is opened. The conventional filling method cannot realize the quantitative filling of the electrolyte in the battery, resulting in electrolyte injection. Insufficient or the height of the electrolyte is more than 20mm above the positive plate and the negative plate, which affects the stability of the battery during charging and discharging, and the electrolyte is easy to overflow
