Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments.
As shown in fig. 1, 2 and 3, in the embodiment of the present utility model: the long-life battery comprises a shell 110, a cover 120 and a body 130, wherein the cover 120 is connected above the shell 110, the body 130 is installed inside the shell 110, a pressure release channel 200 is formed inside the cover 120, the inside and the outside of the shell 110 are communicated through the pressure release channel 200, the pressure release channel 200 comprises a backflow prevention section 210, a straight-through section 220 and a flaring section 230 which are communicated with each other, the diameter of the flaring section 230 is larger than that of the straight-through section 220, a pressure release mechanism is arranged inside the pressure release channel 200 and comprises a supporting plate 221, an inserting rod 222, a limiting plate 223, a spring 224 and a sealing plate 231, the inner wall of the straight-through section 220 is connected with the supporting plate 221, the inserting rod 222 penetrates through the supporting plate 221, the limiting plates 223 and the sealing plate 231 are respectively connected at the two ends of the inserting rod 222, the sealing plate 231 is inserted at the joint of the straight-through section 220 and the flaring section 230, the spring 224 is connected between the supporting plate 221 and the limiting plate 223, and the spring 224 is wound on the outer wall of the inserting rod 222.
In a specific operation, when the internal pressure of the housing 110 is greater than the external pressure, the pressure pushes the sealing plate 231, the inserting rod 222 and the limiting plate 223 to slide at this time, so that the sealing plate 231 moves towards the flared section 230, the sealing of the straight-through section 220 is released, the spring 224 is extruded and deformed, at this time, the inside and the outside of the housing 110 are communicated through the pressure release channel 200, the inside of the housing 110 is rapidly released, after the pressure is balanced, the inserting rod 222, the limiting plate 223 and the sealing plate 231 can be driven to rapidly reset through the elastic action of the spring 224, and therefore the sealing plate 231 seals the straight-through section 220, and the inside and the outside of the housing 110 are different.
The backflow prevention section 210 is of an "S" shaped design.
Through the above design, when the inside and the outside of the housing 110 are communicated, the gas needs to circulate along the S-shaped track to intercept the dust and the water vapor outside, so as to avoid flowing back into the housing 110.
The support plate 221 is hollow.
In other embodiments, the support plate 221 is of a "cross" design.
By the design, the support plate 221 is prevented from sealing the through section 220, and smooth gas circulation is ensured.
The inner diameter of the flared section 230 is gradually increased in a direction that the straight-through section 220 is outside the housing 110.
With the above design, when the sealing plate 231 gradually moves toward the flared section 230, the gap between the sealing plate 231 and the flared section 230 gradually increases, and the pressure release speed increases.
The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting.
