Detailed Description

In order to make the technical solution of the present invention more apparent, the present invention is further described in detail with reference to the following examples, and it should be understood that the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.

Referring to the attached drawings, the plastic shell of the storage battery with the separated exhaust backflow hole plug comprises a shell body 1 and a hole plug, the upper end of the shell 1 is provided with a vent hole 2, two sides of the vent hole 2 are provided with inclined steps 3, the plug is arranged on the vent hole 2 and is attached to the surface of the inclined step 3, the plug comprises a plug body 4, the top of the plug body 4 is provided with a first hole, a filter screen 5 which is aerated but not crossed is arranged in the first hole, a gas passing cavity 6 is arranged in the plug body 4, a frustum 7 is arranged at the top of the gas passing cavity 6, a gas outlet hole 8 is arranged at the topmost part of the frustum 7, the bottom of the air passing cavity 6 is communicated with the vent hole 2 of the shell 1, a backflow channel 9 is arranged at the bottom side of the frustum 7 in the plug body 4, a backflow hole 10 connected with the backflow channel 9 is arranged at the bottom of the frustum 7, and the backflow channel 9 is communicated with the backflow hole 10.

Novel battery plastic casing of structure, at first put into air vent 2 with the stopple, when needs are carminative, gaseous direct through passing gas cavity 6 from 8 discharges of venthole, because can have certain liquid in the gas, consequently, can be in the filtration of advancing filter screen 5 from 8 combustion gas of venthole, filter screen 5 adopts the setting that the gas is not crossed the water, simple saying is very little exactly the mesh number that sets up, liquid just is kept apart, flow down along frustum 7 behind the liquid backward flow, and flow into return channel 9 from return hole 10, and finally flow back to venthole 8.
