Abstract
A base structure of a fan without blades comprises a base and a head provided with an air outlet ring. The top surface of the base is in sphere sliding fit with the bottom surface of the head, a downwards concave sphere is arranged on the top surface of the base, and a downwards convex sphere which matches with the downwards concave sphere is disposed on the bottom surface of the head. A limiting plate is arranged at the bottom of the downwards concave sphere and in sphere sliding fit with the bottom surface of the downwards concave sphere, the middle of the top surface of the limiting plate is fixedly connected with the middle of the downwards convex sphere of the head by a cushion block, and the downwards concave sphere is clamped between the limiting plate and the downwards convex sphere. The top surface of the base is in sphere sliding fit with the bottom surface of the head, so that the head and the air outlet ring can horizontally rotate and swing in the circumferential directions of the spheres in a multidirectional manner, and practicality level of a product is greatly improved. In addition, a positioning mechanism is additionally arranged between the downwards concave sphere and the downwards convex sphere and/or between the downwards concave sphere and the limiting plate so as to avoid the problem that the spheres cannot be positioned after long-term friction. The base structure of a fan without blades is simple and reasonable, and is safe and convenient in operation and long in service life.
