Abstract
The invention discloses an axial flow fan. The axial flow fan comprises a motor connection part, wherein an extension part is arranged on the motor connection part; a plurality of fan blades with larger thickness are centrally symmetrically distributed at the periphery of the extension part; a plane is arranged at the tail end of each fan blade; the fan blades have radian and are of a hollow structure. According to the axial flow fan, the blades which are centrally symmetrically distributed on the main body as a whole body, and each blade is in the hollow structure with the larger thickness and has a certain radian, so that the intensity of the fan blades can be greatly improved through the design. Therefore, the fan blades of the axial flow fan are difficult to transform during working and have higher stability.
Description
Technical field
The present invention relates to a kind of flabellum, or rather, is a kind of axial flow fan blade.
Background technique
Axial-flow blower a kind ofly in industrial production, uses commonplace industry equipment, has comparatively wide application prospect.But the flabellum of the axial-flow blower generally used at present can be out of shape because of long-time use, affects fan work efficiency.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of on-deformable axial flow fan blade.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of axial flow fan blade, comprise a motor coupling portion, described motor coupling portion is provided with an extension part, some flabellum blades are provided with in centrosymmetric distribution in the periphery of described extension part, described each flabellum blade has comparatively heavy thickness, is provided with a plane at the end of described each flabellum blade.
As preferred embodiment of the present invention, described flabellum blade has radian.
As preferred embodiment of the present invention, described flabellum blade is hollow structure.
Due to axial flow fan blade of the present invention be provided with on body entirety be centrosymmetric distribution blade, each blade is arranged to have the hollow structure compared with heavy thickness, and each flabellum is arranged to have certain radian, this design can increase the intensity of flabellum blade greatly, thus make axial flow fan blade not yielding in the course of the work, there is higher stability.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of axial flow fan blade of the present invention;
Fig. 2 is the perspective view of the axial flow fan blade in Fig. 1, is now another visual angle.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides a kind of on-deformable axial flow fan blade.
As shown in Figure 1 and Figure 2, a kind of axial flow fan blade 1, comprise a motor coupling portion 2, described motor coupling portion 2 is provided with an extension part 3, some flabellum blades 4 are provided with in centrosymmetric distribution in the periphery of described extension part 3, described each flabellum blade 4 has comparatively heavy thickness, is provided with a plane 5 at the end of described each flabellum blade 4.
As shown in Figure 1 and Figure 2, described flabellum blade 4 has radian.
As shown in Figure 1 and Figure 2, described flabellum blade 4 is hollow structure.
The axial flow fan blade of this invention is provided with entirety and is centrosymmetric the blade of distribution on body, each blade is arranged to have the hollow structure compared with heavy thickness, and each flabellum is arranged to have certain radian, this design can increase the intensity of flabellum blade greatly, thus make axial flow fan blade not yielding in the course of the work, there is higher stability.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more function module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
