Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric appliance manufacturing, and specifically relates to an anti-impact dust cover for electric appliance manufacturing. BACKGROUND

[0002] The economic development and the technical progress have remarkably improved the living standards of ordinary people, and one of the most intuitive performances is that household appliances are more and more abundant and popular. In order to make the appearance clean and beautiful and have certain strength, the shells of the existing household appliances are mostly made of PP plastic. The PP plastic is polypropylene, which is light, non-toxic and odorless, and has good chemical resistance, heat resistance and electrical insulation. However, a considerable amount of dust is generated in the process of processing the household appliance shell made of PP plastic. In order to ensure the cleanliness of the processing environment and the health of the workers, necessary dust removal equipment needs to be set up. The dust cover is an important structure on the dust removal equipment. It is generally designed with a large opening to suck as much dust as possible. However, this design, combined with the fact that it is often made of thin sheet metal material, directly leads to low impact resistance of the dust cover. When subjected to accidental impact, not only is the dust cover itself prone to deformation, but also the connection position with the upper structure is prone to undesirable displacement, which even affects the normal operation of the dust removal work. Based on this situation, how to improve the impact resistance of the dust cover has become an urgent problem for relevant technical personnel. SUMMARY
