Description

Technical Field

[0001] The utility model belongs to the field of control cabinets, and specifically relates to a dust-proof and heat-dissipating device for a control cabinet. Background Technique

[0002] A control cabinet is an enclosed electrical device used to install, protect, and connect electrical equipment, instruments, and control components. Control cabinets are usually made of metal or plastic materials, with a sturdy shell and appropriate sealing performance to protect the internal equipment from the external environment. They play a crucial role in fields such as industrial automation, power systems, and mechanical equipment;

[0003] According to the application number: 202321480785.8, a dust-proof and heat-dissipating device for a control cabinet is disclosed. This dust-proof and heat-dissipating device for a control cabinet includes a control cabinet body, a first heat dissipation window, and a second heat dissipation window. The first heat dissipation window is arranged on one side of the control cabinet body, and the second heat dissipation window is arranged on the other side of the control cabinet body. A second filter screen is installed inside the second heat dissipation window, and a dust cleaning component for cleaning foreign objects is arranged on one side of the second filter screen inside the second heat dissipation window. The dust cleaning component includes a movable bracket, and a cleaning brush is installed on the movable bracket. When in use, the movable bracket can be moved through a mobile end, so that it moves along the guide groove as a path through the guide block, and the cleaning brush is driven by the movable bracket to clean the dust and fluff adhered to the second filter screen, avoiding the phenomenon of poor air flow caused by the blockage of the filter holes;

[0004] The prior art has well solved the problem that the filter screen filters dust, fluff, and other impurities in the air. As the filtering time prolongs, dust and fluff will adhere to the surface of the filter screen, affecting the air circulation. However, due to the soft material of the fluff, it is easy to wind around the surface of the brush, and the brush cannot be disassembled, cleaned, or replaced. After long-term use, a large amount of fluff will wind around the surface of the brush, thus affecting the cleaning effect on the filter screen.
