In summary, how to avoid causing blast because of the evaporation of electrolyte, to realize the security protection to battery, be
Current those skilled in the art technical problem urgently to be resolved hurrily.
The content of the invention
In view of this, it is an object of the invention to provide a kind of maintenance-free battery, to avoid because of the evaporation of electrolyte
Cause blast, so as to realize the security protection to battery.
In order to achieve the above object, the present invention provides following technical scheme：
Filled in a kind of maintenance-free battery, including cover plate and the battery container with working cavity, the working cavity
There are electrolyte, in addition to safety valve, the safety valve has the leakage fluid dram connected with the working cavity and is in communication with the outside
Gas outlet, and the leakage fluid dram have make steam condense return flow line.
It is preferred that, in above-mentioned maintenance-free battery, the return flow line is spiral flow channel.
It is preferred that, in above-mentioned maintenance-free battery, it is provided with passage, the battery container and is provided with the cover plate
Connect the exhaust passage of the gas outlet and the passage.
It is preferred that, in above-mentioned maintenance-free battery, it is provided with what is coordinated with the passageway seals on the safety valve
Sealing shroud.
It is preferred that, in above-mentioned maintenance-free battery, the gas outlet is arranged on the valve body side of the safety valve.
It is preferred that, in above-mentioned maintenance-free battery, air filter piece is provided with the passage.
It can be seen from above-mentioned technical scheme that, the maintenance-free battery that the present invention is provided includes cover plate and with working chamber
Electrolyte is filled with the battery container of body, working cavity；Also include safety valve, safety valve has the row connected with working cavity
Liquid mouthful and the gas outlet being in communication with the outside, and leakage fluid dram has the return flow line for condensing steam.
When maintenance-free battery produces heat in charging process, when electrolyte is because of heated evaporate, electrolyte is produced
Gas-vapor mix return flow line is entered by leakage fluid dram, so most of gas-vapor mix flows through return flow line and is condensed into liquid
State, working cavity is back to from leakage fluid dram, and a small amount of gas is discharged by the gas outlet of safety valve, it is to avoid the pressure in battery
Increase, so can avoid causing blast because of the evaporation of electrolyte, so as to realize the security protection to battery.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are the present invention
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis
These accompanying drawings obtain other accompanying drawings.
Fig. 1 is the structural representation of safety valve provided in an embodiment of the present invention.
Embodiment
The embodiments of the invention provide a kind of maintenance-free battery, to avoid causing because of the evaporation of electrolyte blast, from
And realize the security protection to battery.
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Accompanying drawing 1 is refer to, maintenance-free battery provided in an embodiment of the present invention includes cover plate and the electricity with working cavity
Electrolyte is filled with pond housing, working cavity；Also include safety valve, safety valve has the leakage fluid dram 2 connected with working cavity
And the gas outlet 5 being in communication with the outside, and leakage fluid dram 2 has the return flow line 3 for condensing steam.
When maintenance-free battery produces heat in charging process, when electrolyte is because of heated evaporate, electrolyte is produced
Gas-vapor mix return flow line 3 is entered by leakage fluid dram 2, so major part gas-vapor mix flows through return flow line 3 and is condensed into
Liquid, working cavity is back to from leakage fluid dram 2, and a small amount of gas is discharged by the gas outlet 5 of safety valve, it is to avoid in battery
Pressure increases, so can avoid causing blast because of the evaporation of electrolyte, so as to realize the security protection to battery.
It is preferred that, return flow line 3 is spiral flow channel.So, gas-vapor mix can be (i.e. continuous along spiral shape
Multiple Z-shaped passages) the direction of return flow line 3 towards gas outlet 5 flow, the premise of less space-consuming can ensured
Under, make return flow line 3 long as much as possible, improve condensation effect.It is understood that above-mentioned return flow line 3 can also be other
Shape, it is such as snakelike, to reach the same effect for condensing steam.
