Description

Technical Field

[0001] The utility model relates to the technical field of dustproof equipment, in particular to a dustproof equipment and a control box. Background Art

[0002] At present, the outer shell of the control box is bulky. When in use, the heat generated by the internal electrical components will make the temperature inside the box higher, and dust will enter the box from the vents, accelerating the aging of the electrical components in the control box and reducing the service life of the electrical components. In severe cases, too much dust may cause short circuits in the electrical components and even cause fires and other accidents. It is necessary to dissipate heat inside the control box while also preventing dust. The existing dust-proof structure is relatively simple, generally filtering close to the filter, but when there is a lot of dust on the filter for a long time, it will cause flow plugging, and it needs to be replaced at this time. In areas with heavy dust, it needs to be replaced frequently, which is cumbersome. Utility Model Content
