Description

Technical Field

[0001] The utility model relates to the technical field of glove box dust removal, in particular to an atmosphere glove box dust removal device. Background Art

[0002] A glove box is a laboratory device that fills the chamber with high-purity inert gas and circulates it to filter out active substances, primarily removing oxygen, carbon dioxide, and organic gases. It is widely used in ultra-pure environments that are water-free, oxygen-free, and dust-free, such as for lithium-ion batteries and materials, semiconductors, supercapacitors, specialty lamps, laser welding, and brazing. Many laboratory operations require a highly clean environment, especially for microscopic and delicate experiments. Dust and debris inside the glove box may contaminate experimental samples or affect the accuracy of experimental results. The glove box is a closed environment, but if there is dust and particles inside, they may be carried out of the glove box by experimental samples or operators, causing cross-contamination and affecting the results of other experiments. Therefore, it is important to ensure that the interior of the box is in a dust-free environment.

[0003] In the prior art, after searching, it was found that a Chinese patent disclosed "a downward-pressure dust removal device for a glove box", and its application number is "202022111454.X".
