Fig. 2 is the schematic diagram of air bleeding valve；
Fig. 3 is the bottom schematic view of air bleeding valve.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Referring to shown in Fig. 1-3, a kind of cylindrical alkaline battery, including cylindrical box hat 1, the diaphragm tube being placed in box hat
2nd, the positive electrode 3 that is placed between diaphragm tube and box hat, the negative material 4 being placed in diaphragm tube, the negative cover 6 in " several " word shape
And the sealing ring 7 of plastic production, the negative cover connect negative current collector 5, the sealing ring includes newel 10, described negative
Pole collector 5 is stretched out through the through hole at the center of the newel, and the outside of negative cover and sealing ring is born in outer bending structure
Sealing ring is pressed on the inner wall of box hat by polar cap, and box hat has interior bending part, the free end of sealing ring and negative cover is covered close
It seals, part-structure noted earlier, is the general technology structure of existing cylindrical alkaline battery, to this, it will not be described, this
The creation of utility model is, at least one air bleeding valve 8 is equipped between the sealing ring and negative cover, the air bleeding valve
Exhaust side is connected with the negative cover, air inlet side is connected with the sealing ring, can discharge the gas of inside battery in outside battery
Portion, the air bleeding valve include valve body 80, and the air inlet side of the valve body is equipped with inlet channel 88, the inlet channel and valve inner
Valve chamber be connected, the taper air inlet of the valve chamber is equipped with taper valve core 81, the taper valve core connecting spring 82, the bullet
The other end of spring is connected with the spring base 84 in adjusting screw 85, and the adjusting screw is connected with the inner thread of the valve body,
Exhaust outlet 86 is formed between the inner wall of the adjusting screw and the valve body.
The bottom connection stop collar 82 of the taper valve core, by portion including the spring subpackage.
