Abstract

The invention relates to a blade-free fan, which comprises an air cylinder. The blade-free fan is characterized in that a base is arranged under the air cylinder, the upper surface of the base is in a concave curve surface, the lower surface of a fixing plate is in a convex curve surface and is connected with the concave curve surface of the base, and a slide plate is arranged between the base and the fixing plate. The blade-free fan has the beneficial effects that the structure is simple, the safety in use is realized, the size is small, air is delivered by the air cylinder, and the air cylinder can rotate by 90 degrees forwards and backwards and rotate by 30 degrees leftwards and rightwards through the installation of the base.

Description

technical field [0001] The invention relates to a fan, in particular to a bladeless fan which can swing freely. Background technique [0002] In the prior art, the air ring of the fan can only move forward and backward, but cannot move left and right, which is inconvenient to use. Contents of the invention [0003] The purpose of the present invention is to avoid the disadvantages of the prior art and provide a fan with simple structure, the air ring can move back and forth, left and right, and a noiseless fan without blades. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a bladeless fan, including a blower, characterized in that a base is installed under the blower; the upper surface of the base is a concave curved surface; the fixing plate It is connected with the concave curved surface of the base; a slide plate is arranged between the base and the fixed plate, and the curvature of the slide plate is consiste...
