Abstract

The utility model discloses a lid of a storage battery with abundant liquid, which comprises a lid body which is provided with a liquid filling hole and a liquid opening plug, wherein the liquid opening plug is provided with a through hole, the upper end of the through hole is led out through a duct, and the inner of an exhaust passage of the liquid opening plug which is formed from the through hole and the duct is provided with an air filtering piece; the upper surface of the lid body is provided with a groove which is communicated with the upper part of the liquid filling hole; the duct is arranged in the groove. The utility model has the advantages of reasonable design and simple structure, since the liquid opening plug is additionally provided with the through hole, the inner of the exhaust passage of the liquid opening plug is provided with the air filtering piece, and electrolyte is not easy to overflow, enhances safety, the upper end of the utility model is led out by the duct, the duct is arranged in different grooves according to requirements, even if the storage battery is placed obliquely, the liquid level of the electrolyte is always below an outlet of the duct, and the electrolyte can also not overflow, and thus, the scope of application of the storage battery with the abundant liquid is enlarged.

Description

The pregnant solution type battery cap

Technical field the utility model relates to a kind of storage battery, particularly the pregnant solution type battery cap.

Background technology is present, and general maintenance free cell is divided into two kinds of lean solution formula and pregnant solution types.Lean solution formula storage battery generally adopts absorption type dividing plate or colloidal electrolyte, electrolyte is less, in use want dehydration inevitably owing to discharging and recharging, battery performance is descended too early, and in use, also will add water midway, not so battery can be ended the life-span in advance, but when this Jia Shui, add how much water and be difficult to judge that water is untimely to be easy to cause battery to break down if add.And the pregnant solution type storage battery has more electrolyte, is not afraid of dehydration, and placement is used but it can not tilt, and overflows corrosion vehicle and article otherwise just have electrolyte.Need the occasion that tilts to place storage battery at electric bicycle etc., all can only adopt lean solution formula storage battery now basically, poor-performing not only, useful life is short, but also will often add water, uses very inconvenience.

Summary of the invention is at the defective and the deficiency of prior art, technical scheme to be solved in the utility model is to provide a kind of pregnant solution type battery cap reasonable in design, simple in structure, it and pregnant solution type cell jar are combined closely, and make the pregnant solution type storage battery also can not overflow electrolyte when tilting to use.

The technical solution of the utility model is as follows: a kind of pregnant solution type battery cap, comprise the lid and the liquid surface bolt that have liquid filling hole, have through hole on the described liquid surface bolt, draw by conduit the upper end of this through hole, is provided with air filter piece in the liquid surface bolt exhaust passage of through hole and conduit formation; The upper surface of described lid is provided with the groove that connects with liquid filling hole top, and conduit places groove.

The described groove that connects with liquid filling hole top can be skewed slot, also can be cannelure.

Described air filter piece places the through hole lower end of liquid surface bolt, and air filter piece can be structure as a whole with liquid surface bolt, also a stopper can be set below air filter piece, and this stopper front end and corresponding with it liquid surface bolt side all have pore.

Described air filter piece places the exit of conduit.

The cover plate that hides liquid surface bolt and groove also is housed on the described lid.

The utility model is reasonable in design, simple in structure, owing to increase through hole on liquid surface bolt, and this through hole lower end is provided with air filter piece, makes electrolyte be not easy to overflow and comes, and strengthened fail safe; Draw by conduit its upper end, and conduit places different grooves as required, even storage battery tilts to place, the liquid level of electrolyte is lower than the outlet of conduit all the time, and electrolyte can not overflow, thereby has enlarged the range of application of pregnant solution type storage battery greatly.
