Problems solved by technology
[0006] In order to make up for the deficiencies of the existing technology, the No. 1 protective cover and the No. 2 protective cover are fixed by clamps and bolts in the prior art. However, when the fan fails or needs to be cleaned, the installation of the No. 2 protective cover needs to be aligned and fixed. Fastened by bolts, loose nuts are easy to fall off, requiring the cooperation of multiple people, complicated operation, and seriously reducing the maintenance efficiency of electric fans. The invention proposes a maintenance-friendly electric fan

The invention belongs to the technical field of household electrical appliances, and specifically relates to an electric fan that is convenient for maintenance, including a body and a base, a fan blade is fixedly connected to a rotating shaft on one side of the body, and a No. 1 protective cover and a fan blade are fixedly connected to the side of the body near the fan blade No. 2 protective cover; a group of fixed shells are evenly distributed on the outer edge of the No. 2 protective cover. In the fixed shell, there is a clamping plate hinged through the revolving pin. The end of the clamping plate away from the revolving pin is fixedly connected with a triangular block; the revolving pin is far away from the extension spring. The middle part of the lever on the side is fixedly connected with the No. 1 pull wire; the side of the No. 2 protective cover away from the body is fixedly connected with a slider, and a button is slidably connected in the slider, and a set of springs is fixedly connected between the button and the inner bottom of the slider. The No. 1 pull wire runs through the side wall of the slider and is fixedly connected to the button; the invention aligns the No. 2 protective cover with the No. 1 protective cover and then presses the No. 2 protective cover. The edge of the No. 1 protective cover passes through the triangular block and is clamped by the clamping plate. Fixed to increase the maintenance efficiency of electric fans.
Description
