Battery liquid-filling valve

Abstract

The invention discloses a battery liquid-filling valve, comprising a body, a valve core, a rotating shaft, a lever, a buoy and a water inlet channel. The battery liquid-filling valve is characterized in that the body (2) is internally provided with a fixed rotating shaft (7); the water inlet channel (3) is arranged at one axial side of the rotating shaft; the upper end of the water inlet channel is connected with a water inlet interface assembly (1); the valve core (4) is assembled at the lower end of the water inlet channel to form a valve device; the rotating shaft is provided with the lever (8) capable of rotating around the rotating shaft; one end of the lever is movably connected with the valve core; and the other end of the lever is movably connected with the body (6). By introducing a lever structure principle, the valve is controlled to be opened and closed under the action of the buoyancy provided by liquid in a storage battery to prompt a user whether the storage battery is lack of liquid or not and when to stop filling the liquid. The invention can effectively avoid the liquid lack of the battery, insufficient liquid filling, excessive liquid feeding and overflowing to damage the storage battery.

Description

technical field [0001] The invention relates to a liquid injection device for a battery, in particular to a liquid injection valve for providing lead-acid battery liquid shortage warning, liquid filling protection and visual prompts. Background technique [0002] At present, most of the liquid filling inlets on the battery are simple liquid injection caps. When the liquid is closed, it is impossible to know whether the battery is short of liquid. Stop adding liquid, and add liquid manually and visually, it is difficult to accurately control the amount of liquid added, and it is easy to cause battery shortage, insufficient liquid, or excessive liquid and overflow to damage the battery. Contents of the invention [0003] In order to overcome the fact that the existing battery liquid filling cap cannot know whether the battery is short of liquid when it is closed, it cannot provide a visual reminder of whether it is full or not, and it cannot automatically stop the liquid fil...

[0003] In order to overcome the fact that the existing battery liquid filling cap cannot know whether the battery is short of liquid when it is closed, it cannot provide a visual reminder of whether it is full when adding liquid, and also It is impossible to automatically stop adding liquid when it is full, and it is easy to cause insufficient liquid or excessive liquid and overflow to damage the battery. The invention provides a liquid-short warning by introducing the principle of a lever structure, and stops when the liquid is full. Injection valve that dispenses liquid and provides visual cues
