Description

CROSS-REFERENCE TO PRIOR APPLICATION

Priority is claimed to Chinese Patent Application No. 202323090516.3, filed on Nov. 15, 2023, the entire disclosure of which is hereby incorporated by reference herein.

FIELD

The present utility model relates to the field of electronic atomization technologies, and specifically, to a battery assembly and an electronic atomization device.

BACKGROUND

An electronic atomization device generally includes key components such as a battery, a circuit board, and a heating element. Battery cores in the components generally include valuable materials such as lithium, cobalt, and nickel. This means that these valuable resources may be wasted or cannot be recovered when the electronic atomization device is discarded. In addition, if the discarded electronic atomization device is treated properly, harmful substances in the battery may pollute soil and water sources.

With increasing global awareness of sustainability and environmental protection, countries and regions have formulated a series of environmental regulations and policies to reduce adverse environmental impacts of discarded electronic products. As one of the environmental regulations and policies, the European Environmental Protection Act defines requirements for easy disassembling of electronic products with battery cores for consumers. A core objective of this initiative is to promote sustainable lifecycle management of the electronic products and reduce the burden of discarded electronic devices on an environment.

However, existing disposable electronic atomization devices do not have a quick-disassembling function of a battery core. Generally, a battery housing can be decomposed only through a professional means, and then a battery core is taken out, which causes inconvenience for subsequent classification and recovery of the battery core.

SUMMARY

In an embodiment, the present invention provides a battery assembly to mount a battery core, comprising: a holder configured to mount the battery core; a battery protection tube; and a bottom cover located on one end of the battery protection tube, wherein the battery protection tube is sleeved on the holder and covers the battery core, wherein a first buckle part is arranged on the bottom cover, and a second buckle part configured to the first buckle part is arranged on the holder, wherein the bottom cover is rotated relative to the holder, and wherein the first buckle part is in a buckle connection with the second buckle part, or the first buckle part is separated from the second buckle part.
