Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] The button battery 10 provided by the embodiment of the present invention is used to provide electric energy, especially for powering wearable electronic devices; of course, in other embodiments of the present invention, the button battery 10 can also be used to supply power for other electronic devices, here Not uniquely limited.

[0027] please combine Figure 1 to Figure 10 , the button battery 10 provided by the present invention will now be described. A button battery 10 includes a casing 100 and a battery body 200 . In this embodiment, the battery body 200 generates electrical energy through electrochemical action. Specifically, the housing 100 includes a first housing 110, a second housing 120 and an insulator 130 electrically isolating the first housing 110 and the second housing 120, the first housing 110, the second housing 120 and t...

Abstract

The invention provides a button battery and electronic equipment. A button battery includes a casing, the casing has a first accommodating cavity; and a battery body, the battery body is accommodated in the first accommodating cavity. The shell is provided with a first through hole communicating with the first accommodating cavity, and a cover is provided in the first accommodating cavity, the cover is used to seal the first through hole, the cover is provided with a second through hole, and the second through hole is arranged on the cover. The two through holes are sealed by an explosion-proof membrane, which can be melted at a preset temperature or broken at a preset pressure, so that the first accommodating cavity is connected to the first through hole through the second through hole, and the first through hole is along its axis The projection of the direction on the cover does not coincide with the explosion-proof membrane. The explosion-proof membrane can be melted at a preset temperature or broken at a preset pressure to ensure that the explosion-proof membrane is melted or broken when the button battery is abnormally charged and discharged or the positive and negative electrodes are short-circuited, and the gas in the first accommodating cavity can pass through the second through hole And discharged by the first through hole.

Description

【Technical field】 [0001] The invention relates to the technical field of batteries, in particular to a button battery and electronic equipment with safety air holes. 【Background technique】 [0002] With the development of electronic devices, especially wearable electronic devices, batteries are required to be more miniaturized. Therefore, the frequency of use of button batteries as miniaturized batteries is increasing. [0003] A button battery is also called a button battery, which includes a casing and a battery body housed in the casing. When the button battery is abnormally charged and discharged or the positive and negative electrodes are short-circuited, the temperature inside the casing will rise sharply, and the gas generated by the battery body will cause the internal pressure of the casing to increase, the casing will expand, and eventually the button battery will explode and cause a safety accident. [0004] Therefore, it is necessary to provide a button battery ...
