Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 3, a fan blade capable of increasing an air supply amount includes a fixing ring 1 and blades 2, the blades 2 are seven and are fixedly connected to an outer side of the ring body of the fixing ring 1 in a centrosymmetric manner, the blades 2 include a protruding portion 21, one side of the protruding portion 21 is fixedly connected with a corrugated portion 22, one side of the corrugated portion 22 away from the protruding portion 21 is fixedly connected with a blade edge 23, and a bottom of the blade edge 23 is fixedly connected with a protrusion tip 24.
Specifically, the protruding portion 21, the corrugated portion 22, the blade edge 23 and the protruding tip 24 are integrally formed.
In this embodiment, the integrated into one piece structure can make the structure of blade 2 more firm, increases life.
Specifically, the shape of the blade edge 23 is a butterfly wing shape.
In the embodiment, the air output is increased by utilizing the bionic shape of the butterfly wing.
The utility model discloses a theory of operation and use flow: when the fan is used, the fixing ring 1 is fixed on a rotating shaft of the motor, the blades 2 rotate, the protruding tips 24 and the blade edges 23 of the blades 2 are designed to be butterfly wing shapes in bionic shapes, the air supply amount is increased, the three tracks of the protruding portions 21 of the blades 2 are increased, the air supply amount is increased, and the corrugated portions 22 are designed to enable the fan blades to supply uniform air from the centers of the fan blades.
In summary, in the fan blade capable of increasing the air supply volume, the convex tip 24 and the blade edge 23 of the blade 2 are designed into a butterfly wing shape, so that seven blades 2 correspond to the air supply volume of fourteen blades 2, the corrugated part 22 of the blade 2 is designed to supply air from the center of the blade, the wind power is uniform, and the three tracks of the convex part 21 of the blade 2, which correspond to the air supply volume of twenty-one blade 2, greatly increase the air supply volume of the fan.
It should be noted that, in this document, terms such as "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
