Detailed ways

The embodiments of the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and therefore are only examples, and cannot limit the scope of protection of the patent.

As shown in FIG. 1 and FIG. 2, the embodiment of the present invention provides a visual suspension fan, including a fan head 1, a transparent rotating member 2 rotatably connected to the front end of the fan head 1, and a ring disposed on the outer periphery of the transparent rotating member 2. a plurality of fan blades 3, an annular fan grille 4 disposed around the outer circumference of the transparent rotating member and surrounding the fan blade 3, a front transparent support member 5 correspondingly disposed on the front side of the transparent rotating member 2, and correspondingly disposed in the transparent rotation The rear transparent support member 6 on the rear side of the member 2, the outer peripheral edge of the front transparent support member 5 is connected to the annular fan grill 4, and the rear transparent support member 6 is supported and connected between the fan head 1 and the annular fan grill 4.

In operation, the fan blade 3 rotates together with the transparent rotating member 2 to accelerate the air to generate air, and the transparent rotating member 2, the front transparent supporting member 5 and the rear transparent supporting member 6 in the middle of the fan are transparent materials, and the outer ring of the fan Partly adopting the structure of the conventional annular fan net cover 4 and the fan blade 3, from the user's visual experience, there is no support between the annular fan net cover 4 and the fan head 1, and the fan blade 3 and the annular fan net cover 4 seem to be in the air. Suspension, giving people a wonderful visual experience, subverting the structural shape of the traditional fan, beautiful appearance, with high ornamental and aesthetic value.

The transparent rotating member 2, the front transparent supporting member 5 and the rear transparent supporting member 6 in the middle of the fan of the present embodiment have a smooth and seamless surface structure, such that the front transparent supporting member 5, the rear transparent supporting member 6 and the transparent rotating member 2 are provided. There will be no traces when it improves the perspective. Moreover, the front transparent support member 5 is recessed inwardly with respect to the annular fan grill 4, and the rear transparent support member 6 is recessed inwardly with respect to the annular fan grill 4 so that the front transparent support member 5, the rear transparent support member 6 and the annular fan The cross-section of the structure formed by the net cover 4 is dumbbell-shaped, which makes it more three-dimensional and more beautiful in appearance.
