Abstract
The utility model relates to a simple highly air permeable acid spray preventing lead acid battery cover, which belongs to the storage battery technology field, and is used for solving the problem of acid spray when the storage battery is over charged. The lead acid battery cover is composed of a big cover and a gas exhausting cover. The butting surfaces of the big cover and the gas exhausting cover are heat sealed, and gas exhausting positions are symmetrically arranged at the two sides of the gas exhausting cover. The lead acid battery cover is characterized in that each gas exhausting structure is composed of a gas filtering sheet cover and first and second gas filtering sheets, the two gas filtering sheets are mutually parallel and arranged in parallel with the heat sealing surface of the gas exhausting cover, the gas filtering sheet cover is positioned on the two gas filtering sheets, and a gas channel is formed between the two gas filtering sheets and the gas filtering sheet cover. By adopting the design of the gas chamber formed by two gas filtering sheets and the gas filtering sheet cover, gas water separation can be completely performed to the acid liquor when passing through the gas filtering sheets and the gas channel, through the condensation of the gas chamber, water and the acid liquor are separated, the liquid is blocked, and the gas can be smoothly exhausted out of the storage battery, therefore, the functions of gas filtering sheets with large gas permeation amount and prevention of acid liquor overflow can be achieved. Through the improvement, the internal pressure of the storage battery can be reduced and acid spray of the storage battery can be prevented after the lead acid battery cover is installed on the storage battery.
Description
Technical field
It is good and have a lead-acid battery lid that prevents to spray acid function that the utility model relates to a kind of vehicle battery parts, particularly permeability, belongs to the battery technology field.
Background technology
Lead acid accumulator generally is made up of a plurality of single lattice batteries, in each single lattice battery sulfuric acid electrolyte is housed, in battery charging process, except that normal electrochemical reaction, battery also can generate heat, follow the reaction of brine electrolysis, the steam of generation is carrying sulfuric acid secretly and hydrogen or oxygen gas is discharged by the steam vent on the battery cap together.Air filter piece all is equipped with in the one or both sides of general battery cap, and it can allow unnecessary gas discharge the sour water liquid filtering, keeps the scope of inner pressure of battery a safety.But at present the design of battery cap all is a slice air filter piece, and its is difficult to effective filter acid water vapor body, and under extreme conditions when overcharging (as) can not satisfy exhaust filter acid function simultaneously.If the unobstructed acid solution that has of exhaust is overflowed, and, acid solution can cause exhaust not smooth if not overflowed.Usually way is to adopt low Air permenbility air filter piece, and its result can cause inner pressure of battery to rise and produce potential safety hazard.So need a kind of novel exhaust structure, use the air filter piece of big Air permenbility to take into account exhaust and both contradiction of filter acid simultaneously.
Summary of the invention
The utility model is used to overcome the defective of prior art and provides a kind of unobstructed high ventilative blowout prevention lead plumbate acid accumulator of simple type that can prevent effectively that acid solution from leaking of exhaust that can keep under the charge in batteries condition to cover.
The alleged problem of the utility model solves with following technical proposals:
The high ventilative blowout prevention lead plumbate acid accumulator lid of a kind of simple type, form by big lid and exhaust cap, the two interface heat-sealing, described exhaust cap bilateral symmetry is provided with exhaust structure, its special feature is: described each exhaust structure is made of air filter piece lid 2 and first, second air filter piece 3,4, described two air filter pieces are parallel to each other and be arranged in parallel with the exhaust cap heat cover, and the air filter piece lid places on two air filter pieces, form gas passage 5 between two air filter pieces and the air filter piece lid.
The high ventilative blowout prevention lead plumbate acid accumulator lid of above-mentioned simple type, described first air filter piece 3 connect air admission hole 6, the second air filter pieces 4 that communicate with the internal storage battery air flue and are communicated with the steam vent 8 that leads to the storage battery outside on the exhaust cap.
The utility model improves at the problem that spray acid easily takes place when overcharging existing storage battery, it adopts the design that is made of gas passage two air filter pieces and air filter piece lid, and gas must could be discharged storage battery through first air filter piece, gas passage, second air filter piece.Said process makes acid solution fully carry out gas-water separation, condenses, divides dried up and acid solution, holds back liquid, makes outside the smooth and easy discharge storage battery of gas, reaches when using big Air permenbility air filter piece effectively to prevent the purpose that acid solution is overflowed.Through this improvement, after being installed in the utility model on the storage battery, can reduce when overcharging accumulator internal pressure and prevent storage battery spray acid, make storage battery than prior art significant progress arranged on blowout prevention acid ability, storage battery safety in utilization and durability are greatly improved.

Fig. 3 is the A-A cutaway view of Fig. 2;
Fig. 4 is the big lid structural representation of the utility model (after removing exhaust cap).
Each parts label is expressed as follows among the figure: 1. exhaust cap; 2. air filter piece covers; 3. first air filter piece; 4. second air filter piece; 5. gas passage; 6. air admission hole; 7. big lid; 8. steam vent; 9. exhaust structure.
Embodiment
Referring to Fig. 1, Fig. 4, the utility model is made up of big lid 7 and exhaust cap 1, and the two interface heat-sealing back forms battery cap.
Referring to Fig. 1～Fig. 3, be provided with exhaust structure 9 in the exhaust cap bilateral symmetry, each exhaust position comprises 2 and two air filter pieces 3,4 of air filter piece lid.Two air filter pieces are circular, and they are parallel to each other and be arranged in parallel with exhaust cap 1 heat cover, and the air filter piece lid places on two air filter pieces, form gas passage 5 between two air filter pieces and the air filter piece lid.First air filter piece 3 connects air admission hole 6, the second air filter pieces 4 that communicate with the internal storage battery air flue and is communicated with the steam vent 8 that leads to the storage battery outside on the exhaust cap.Like this, the gas in the storage battery must be discharged storage battery through steam vent 8 again by air admission hole 6 through air filter piece 3, gas passage 5, air filter piece 4.
Structure of the present utility model can prevent spray acid and guarantee that exhaust is smooth and easy under the extreme condition of work of storage battery, its principle is: speed rapid drawdown after the acid solution of sweeping along the gas ejection in the storage battery is being passed through the aperture of first air filter piece 3, acid solution is condensed and is trapped in the gas passage 5, gas is then discharged in the storage battery by second air filter piece 4, two air filter pieces all use the air filter piece of big Air permenbility, thereby accumulator internal pressure is reduced, eliminate safe hidden trouble.
