Abstract
The utility model discloses an anti-explosion battery. The anti-explosion battery comprises a case, wherein two contacts are arranged on the case, a battery raw material is arranged in the case, a positive electrode and a negative electrode of the battery raw material are respectively connected with the two contacts, a bleeder hole is formed in the shell, a flexible stopper is arranged in the bleeder hole in an interference fit manner, a chuck is arranged at one side of the stopper, one side of the chuck is attached to the case, the other side of the chuck is attached to the battery raw material, an air channel is arranged on the chuck, an air hole is formed in the side wall of the stopper, the air channel and the air hole are communicated, and the distance from the air hole to the chuck is less than the wall thickness of the case. According to the anti-explosion battery, the explosion of the battery can be effectively prevented.
Description
Technical field
The utility model relates to the battery technology field, relates in particular to anti-explosion battery.
Background technology
Recently, Zhejiang industrial and commercial bureau has circulated a notice of the sampling result to 36 sections of mobile phones, wherein qualification rate is only 25%, the hidden danger that most of mobile phones all exist battery easily to blast, its reason is that the battery in mobile phone may be because of the short circuit heat-dissipating, the gas of battery point is led off nowhere and is blasted, lithium battery in conventional mobile phone generally is connected the both positive and negative polarity of the former material of battery with the contact on battery container, there is an aspirating hole on battery container, after packing battery container into, the former material of battery, by aspirating hole, the gap between battery container and the former material of battery is vacuumized to injected material, and then aspirating hole is sealed.If this battery is when battery short circuit, battery is subject to the pyrogen material to discharge a large amount of gas, and these gases can't be excreted to the outside of battery, and therefore this battery is easy to blast, and affects user's life security.
Summary of the invention
The utility model, for the prior art deficiency, provides anti-explosion battery, and this kind of anti-explosion battery can reduce the possibility of battery explosion, improves the fail safe that battery is used.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: anti-explosion battery, comprise housing, be provided with two contacts on described housing, be provided with the former material of battery in described housing, the both positive and negative polarity of the former material of described battery connects respectively two described contacts, on described housing, aspirating hole is set, in described aspirating hole, interference is provided with soft stopper, described stopper one side is chuck, the described chuck one side described housing opposite side former material of described battery of fitting of fitting, be provided with air flue on described chuck, be provided with pore on described plug end wall, described air flue communicates with described pore, described pore is less than the wall thickness of described housing to the distance of described chuck.Aspirating hole is set for the state that is evacuated of the space by between housing and the former material of battery, then injected material between housing and the former material of battery, stopper is blocked aspirating hole by interference fit under normal circumstances, when battery short circuit or collision, enclosure interior produces a large amount of gas, enclosure interior air pressure increases can be by stopper toward external pressure, when the past external pressure of stopper, pore will communicate with outside, thereby the gas in housing will flow out to by air flue the air pressure reduction of outside enclosure interior, after air pressure reduces, because stopper is flexible material, therefore aspirating hole is blocked in the position that originally stopper is returned to again, so just effectively prevented battery explosion.
In technique scheme, preferred, described housing comprises upper shell and the lower house that complements each other to form confined space.For convenient processing, housing is divided into to upper shell and lower house.
The utility model compared with prior art, have following beneficial effect: the utility model arranges aspirating hole for the state that is evacuated of the space by between housing and the former material of battery, then injected material between housing and the former material of battery, stopper is blocked aspirating hole by interference fit under normal circumstances, when battery short circuit or collision, enclosure interior produces a large amount of gas, enclosure interior air pressure increases can be by stopper toward external pressure, when the past external pressure of stopper, pore will communicate with outside, thereby the gas in housing will flow out to by air flue the air pressure reduction of outside enclosure interior, aspirating hole is blocked in the position that originally stopper is returned to again after air pressure reduces, so just effectively prevented battery explosion.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment.
The structural representation that Fig. 2 is stopper in the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1 to Fig. 2, anti-explosion battery, comprise housing 1, be provided with two contacts on described housing 1, be provided with the former material 2 of battery in described housing 1, the both positive and negative polarity of the former material 2 of described battery connects respectively two described contacts, on described housing 1, aspirating hole 3 is set, the interior interference of described aspirating hole 3 is provided with soft stopper 4, described stopper 4 one sides are chuck 41, the described chuck 41 1 sides described housing 1 opposite side former material 2 of described battery of fitting of fitting, be provided with air flue 411 on described chuck 41, be provided with pore 42 on described stopper 4 sidewalls, described air flue 411 communicates with described pore 3, described pore 3 is less than the wall thickness of described housing 1 to the distance of described chuck 41, for convenient processing, described housing 1 comprises upper shell 11 and the lower house 12 that complements each other to form confined space.
Aspirating hole 3 is set for the state that is evacuated of the space by between housing 1 and the former material 2 of battery, then injected material between housing 1 and the former material 2 of battery, stopper 4 is blocked aspirating hole 3 by interference fit under normal circumstances, when battery short circuit or collision, the a large amount of gas of housing 1 inner generation, housing 1 air pressure inside increases can be by stopper 4 toward external pressure, when stopper 4 during toward external pressure pore 42 will with housing 1 exterior, thereby the gas in housing 1 will flow out to by air flue 411 the air pressure reduction of housing 1 outside housing 1 inside, aspirating hole 3 is blocked in the position that originally stopper 4 is returned to again after air pressure reduces, so just effectively prevented battery explosion.
