Compared with the prior art, the utility model discloses the benefit that block with exhaust apparatus has lies in: 1 ) simple structure, it is convenient to make, 2 )Ventilative device is not integrated into one piece with the block, can change ventilative device at any time, 3 )The through hole can reduce the processing degree of difficulty directly as annotating the liquid hole.
Description
[technical field]
This utility model relates to cell safety technical field, particularly relates to a kind of block with exhaust apparatus.
[background technology]
Lithium ion battery has high-energy-density and various excellent properties, therefore applies more and more universal.Cylinder
Shape lithium ion battery is due to its standardized size, ripe technique and equipment, in lithium ion battery market
Occupy important share.
The extensive application of lithium ion battery so that it is safety increasingly becomes the problem that people pay close attention to, study.
At present cylindrical lithium ion battery high power charging-discharging, overcharge when, internal temperature of battery is drastically gone up
Rising, now, electrolyte decomposition produces substantial amounts of gas, and along with the increase of gas, inner pressure of battery increases, when
Intrinsic pressure reach certain value it is possible to can set off an explosion, cause potential safety hazard.
To this end, Chinese patent literature notification number CN201904383U discloses a kind of battery cap, described electricity
Basin lid cap includes that cover plate, screening glass and orifice plate, described cover plate are provided with cover board hole, and described orifice plate is provided with
Air-vent, described screening glass is provided with protecting film, and described cover plate, screening glass and orifice plate are tightly connected successively,
Described cover plate is provided with the destruction parts for destroying protecting film, the position of described destruction parts and protecting film
Position is corresponding.Along with the increase of inner pressure of battery, excessive air pressure may break through protecting film or protecting film exists
Under excessive air pressure, deforming contact is to cover plate, is finally punctured by the destruction parts of cover plate, gives battery in this way
Internal pressure relief.
When discharging excess air, at least there is following defect in existing battery cap: 1) use of protecting film is
Disposably, relatively costly；2) capping structure is complicated, makes and mounting process is loaded down with trivial details；3) it is not easy to greatly
Promoting the use of of batch.
It is necessary that providing a kind of has the block of exhaust apparatus to overcome the deficiencies in the prior art in consideration of it, real.
[utility model content]
It is low that the purpose of this utility model is to provide a kind of cost of manufacture, replaceable gas permeable devices, mounting process letter
Single block with exhaust apparatus.
To achieve these goals, this utility model provides a kind of block with exhaust apparatus, described lid
Offer at least pass through aperture on cap, the gas permeable devices communicated with through hole, institute are installed in described through hole
Being equiped with gas permeable material in stating gas permeable devices, this gas permeable material has unidirectional gas penetration ability and liquid can not
Passing through, gas permeable devices is further opened with gas outlet.
Have a kind of improvement of the block of exhaust apparatus as this utility model, described through hole cross section is platform
Scalariform, is provided with female thread in it, gas permeable devices is provided with the external screw thread combined with it.
There is a kind of improvement of the block of exhaust apparatus, described gas permeable devices and through hole as this utility model
Between be equipped with annular sealing ring.
Have a kind of improvement of the block of exhaust apparatus as this utility model, described gas permeable devices includes fastening
Upper-lower casing together, described gas permeable material is installed between upper-lower casing.
Compared with prior art, this utility model has the block of exhaust apparatus and has the advantage that: 1) knot
Structure is simple, easily manufactured；2) gas permeable devices is the most one-body molded with block, can change gas permeable devices at any time；
3) through hole can be directly used as liquid injection hole, reduces difficulty of processing.
[accompanying drawing explanation]
Fig. 1 is the structural representation that this utility model has the block of exhaust apparatus.
[detailed description of the invention]
In order to make the purpose of this utility model, technical scheme and Advantageous Effects become apparent from understanding, below
In conjunction with the drawings and specific embodiments, this utility model is further elaborated.It should be appreciated that
Detailed description of the invention described in this specification is only used to explain this utility model, is not intended to limit
This utility model.
Refer to shown in Fig. 1, this utility model provides a kind of block 100 with exhaust apparatus, described lid
The rounded shape of cap 100, it is for covering the housing at cylindrical battery.One is offered horizontal in block 100
Cross section is step-like through hole 10, and through hole is provided with female thread near one end of battery container, described in run through
The gas permeable devices 20 communicated with through hole is installed in hole.
The cross section of gas permeable devices 20 is consistent with the cross section of through hole 10, and it is upper that it includes snapping together
Lower house, is equiped with gas permeable material 30 between upper-lower casing, this gas permeable material 30 has unidirectional gas penetration energy
Power and liquid can not pass through.Gas permeable devices 20 is further opened with gas outlet 21, in order to by gas permeable devices 20 with pass through
Perforation 10 combines, and gas permeable devices 20 is provided with the external screw thread combined with it.
It is so to assemble and work that this utility model has the block of exhaust apparatus: first pass through through hole 10
Fluid injection, after fluid injection completes, then puts into the sealing ring 40 of annular on the step of through hole, then by gas permeable devices
In precession through hole.High power charging-discharging, overcharge when, if internal temperature of battery steeply rises,
Electrolyte decomposition produces substantial amounts of gas, and along with the increase of gas, inner pressure of battery increases, reaches one when intrinsic pressure
During definite value, other will enter the upper of gas permeable devices by the passage that through hole 10 communicates with gas permeable devices 20
In lower house, finally, gas can be discharged into outside from penetrating gas permeable material from the gas outlet 21 of gas permeable devices.
This utility model has the block of exhaust apparatus, is not restricted in description and embodiment be retouched
State, for the personnel of familiar field, be therefore easily achieved additional advantage and amendment, therefore do not carrying on the back
In the case of the spirit and scope of the general concept limited from claim and equivalency range, this utility model
Be not limited to specific details, representational equipment and shown here as with describe examples shown.
