Abstract

The utility model discloses a rich liquid type sealed battery cover, comprising a body, lattice chambers uniformly distributed on the body, a knockout core hole between the lattice chambers, a liquid feeding hole, a liquid bolt matching with the liquid feeding hole, a pole hole, an exhaust apparatus and air filtering pieces. The rich liquid type sealed battery cover is characterized in that the utility model also comprises a labyrinth which is nested in the lattice chambers to form a condensing chamber together with the lattice chambers. The exhaust apparatus and the body are provided with an integrated structure, and the air filtering pieces are arranged in the exhaust apparatus. The utility model has reasonable design, easy machining and good sealing effect. One-off heat seal is enough in the process of production, which greatly improves the production efficiency and reduces the cost.

Description

Pregnant solution type sealed cell lid

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

Background technology is present, general pregnant solution type sealed cell is stamped two kinds of structures, a kind ofly form by big lid and tegillum, the lattice chamber and the labyrinth of big lid are structure as a whole, must be when producing through twice heat-sealing, the big lid of heat-sealing earlier adds electrolyte then for the first time, seal tegillum again, do the air-tightness experiment at last.Three big shortcomings are arranged like this: one is that the manpower and materials cost of twice heat-sealing is big, and production efficiency is low; The 2nd, the heat-sealing leak rate is higher, in case gas leakage inconvenience is done over again, wastes bigger; The 3rd, when dispatching from the factory, storage battery added electrolyte, do not need could use behind the additional electricity if sell for a long time, trouble.On the body of another kind of pregnant solution type sealed cell lid relief valve device is housed, relief valve device is made of emergency valve seat, safety valve and cover plate, when the air pressure that produces in, the storage battery undesired when charge in batteries was too high, safety valve was difficult for opening, and can cause storage battery blow-up, distortion and damaged; When the air pressure that produces is very big, also can wash air filter piece and cover plate open, acid mist is leaked.

Summary of the invention is at the defective and the deficiency of prior art, and the purpose of this utility model is to provide the pregnant solution type sealed cell lid of a kind of reasonable in design, handling ease, good sealing effect.

The technical solution of the utility model is as follows: a kind of pregnant solution type sealed cell lid, comprise the core-drawing hole between equally distributed lattice chamber, the lattice chamber, liquid filling hole, the liquid surface bolt that cooperates with liquid filling hole, pole hole, exhaust apparatus and air filter piece on body, the body, its improvements are: it also comprises the labyrinth, it is indoor that described labyrinth is embedded in lattice, and the dative chamber constitutes condensation chamber together; Exhaust apparatus and body are structure as a whole, and air filter piece is contained in the exhaust apparatus.

Beneficial effect: the utility model is reasonable in design, handling ease, good sealing effect, only needs once heat-sealing to get final product when producing, and has improved production efficiency greatly, has reduced cost.

Description of drawings is further described the utility model below in conjunction with accompanying drawing:

Fig. 1 is a front view of the present utility model.

Fig. 2 is a rearview of the present utility model.

Fig. 3 is the A-A profile of Fig. 2.

Fig. 4 is the rearview in the utility model labyrinth.

Fig. 5 is the left view in the utility model labyrinth.

Fig. 6 is the structural representation of the utility model liquid surface bolt.

Embodiment is shown in accompanying drawing 1-6, a kind of pregnant solution type sealed cell lid, comprise the core-drawing hole 3 between equally distributed lattice chamber 2, the lattice chamber 2 on body 1, the body 1, liquid filling hole 4, the liquid surface bolt 5 that cooperates with liquid filling hole 4, pole hole 6, exhaust apparatus 8 and air filter piece 10, in addition, it also comprises labyrinth 7; Described labyrinth 7 is embedded in the lattice chamber 2, and dative chamber 2 constitutes condensation chamber together; Described exhaust apparatus 8 is structure as a whole with body 1, after the valve control device 11 that is made of valve control cap 12 and valve control seat 13 is taked tight fit with air filter piece 10, is contained in the exhaust apparatus 8.The utility model can also have the aluminium foil sealing 14 that a size can cover all liquid filling holes 4.

The utility model production technology is simple, adopts once heat-sealing, does not need liquid feeding just can do the air-tightness experiment, has effectively reduced operation; But dispatch from the factory according to selling the actual conditions liquid feeding when storage battery dispatches from the factory, also liquid feeding does not dispatch from the factory.When liquid feeding dispatched from the factory, liquid filling hole 4 usefulness liquid surface bolts 5 sealed; When liquid feeding does not dispatch from the factory, cover on liquid filling hole 4, tear aluminium foil sealing 14 during use off, need not charge behind the liquid feeding and just can directly use with aluminium foil sealing 14.

Operation principle: the gas that contains moisture and acid mist that rich solution in the storage battery above the electrode group and electrode group generate rises, in the condensation chamber that dative chambers 27, labyrinth constitute, flow, fall after moisture and the acid mist cooling aggegation, the gas that partly contains moisture and acid mist is entered the lower end of exhaust apparatus 8 by core-drawing hole 3, through the filtration of air filter piece 10, moisture and acid mist continue condensation, in the storage battery that falls back, gas is then discharged outside the body 1 by exhaust duct 9, thereby has reached the purpose of not revealing acid mist.
