Problems solved by technology

[0005] Because the probability of battery leakage is much greater than that of explosion, some manufacturers pay more attention to the problem of battery leakage. The design of the battery seal does not include an explosion-proof valve, or the design of the explosion-proof valve is unreasonable. When the explosion-proof valve needs to be opened, there is no open normally
Such a battery has good leakage resistance performance, but the explosion-proof performance is not guaranteed.
Some manufacturers pay attention to the explosion-proof performance of the battery, but the leakage resistance of the battery may be poor

Embodiment 1

[0041] In this embodiment, nylon 66 is selected as the material of the battery sealing ring, and the injection molding temperature is controlled at 200-320°C. The sealing ring explosion-proof valve adopts a "|" shape explosion-proof valve sealing ring, and the thickness of the explosion-proof valve is 0.1mm. Use this sealing ring to assemble an LR6 battery, and the battery is numbered 1#. Figure 4 It is a top view of the sealing ring of the first embodiment of the present invention.

Embodiment 2

[0043] In this embodiment, nylon 66 is selected as the material of the battery sealing ring, and the injection molding temperature is controlled at 200-320°C. The sealing ring explosion-proof valve adopts two "|" shape explosion-proof valve sealing rings, and the thickness of the explosion-proof valve is 0.1mm. Use this sealing ring to assemble an LR6 battery, and the battery is numbered 2#. Figure 5 It is a top view of the sealing ring of the second embodiment of the present invention.

Embodiment 3

[0045] In this example, the material of the battery sealing ring is nylon 66, and the injection molding temperature is controlled at 200-320°C. The sealing ring explosion-proof valve adopts three "|" shape explosion-proof valve sealing rings, and the thickness of the explosion-proof valve is 0.1mm. Use this sealing ring to assemble an LR6 battery, and the battery is coded as 3#. Image 6 It is a top view of the sealing ring of the third embodiment of the present invention.

Abstract

The invention provides an alkaline battery sealing ring, the sealing ring is located between the battery bottom cover, the central column and the battery casing, and is used to seal the alkaline battery, the central column is located at the center of the sealing ring, the An explosion-proof valve is arranged on the sealing ring; the explosion-proof valve is a weak groove on the sealing ring along the direction of the central column, and the weak groove opens on the side of the sealing ring close to the bottom cover of the battery; the explosion-proof valve is uniform or non-uniform Arranged on the sealing ring; the shape of the weak groove is "one" or "V" or "U" or "Y".

Description

technical field [0001] The invention relates to an alkaline battery, in particular to an alkaline battery sealing ring. Background technique [0002] With the development of our country, people's living standards are constantly improving, people's awareness of environmental protection is constantly increasing, and people are using more and more green and pollution-free alkaline batteries. Compared with traditional carbon batteries, alkaline batteries have the following advantages: (1) high-power discharge performance is good, and the service time of alkaline batteries is more than 5 times that of carbon batteries; (2) low-temperature discharge performance is good, at minus 20 Alkaline batteries can still work at high temperature, but carbon batteries can hardly discharge electricity at around zero degrees; (3) The utilization rate of active materials in alkaline batteries is greater than that of carbon batteries, which is conducive to the rational use of resources; (4) Alkal...
