The utility model has the advantages of powerful air outlet, simple and easy processing and the like.
Description
The technical field is as follows:
the utility model belongs to the technical field of the fan, refer in particular to a fan blade.
Background art:
at present, traditional electric fan adopts the motor to drive a plurality of flabellums and carries out the mode of rotation and continuously supply air, to the processing of flabellum, often comparatively difficult to there is certain wind-force to run off in traditional flabellum rotation process, makes electric fan work efficiency low.
The invention content is as follows:
the utility model aims at providing a fan blade that wind-force is powerful and easily processing.
The utility model discloses a realize like this:
the utility model provides a fan blade, includes the pivot mounting disc, and the center of pivot mounting disc is provided with the mounting hole, the outside circumference shaping of pivot mounting disc has a plurality of flabellum mounting panels that outwards extend, and the below shaping of flabellum mounting panel has the flabellum of downwardly extending.
The utility model discloses further set up to, the outside shaping of flabellum mounting panel has annular retaining ring, and the shaping has the blow vent between adjacent flabellum mounting panel and the annular retaining ring.
The utility model discloses further set up to, the blow vent is the same with the size of flabellum.
The utility model discloses further set up to, the blow vent comprises long limit, minor face and arc limit, the flabellum is by long limit downwardly extending and shaping.
The utility model discloses further set up to, the shaping has the recess of downward arch on the flabellum mounting panel.
The utility model discloses further set up to, the flabellum with the flabellum mounting panel is connected perpendicularly.
The utility model discloses further set up to, the quantity of flabellum is nine
Compared with the prior art, the utility model outstanding advantage is:
1. the fan blade provided by the utility model adopts an integrated forming mode, and depends on the fan blade formed at the lower end of the fan blade mounting plate, so that the whole processing process is simpler, the angle of the fan blade does not need to be adjusted, and meanwhile, the design mode can be provided with more fan blades than the traditional design mode, so that the air outlet effect is stronger;
2. the utility model further enables the annular retainer ring formed at the outer side of the fan blade mounting plate to reinforce the connection strength between the fan blade mounting plate and the fan blade, thus ensuring the high-efficiency use in the rotating process;
3. the size of the vent and the size of the fan blade in the utility model are the same, so that the air output and the resistance overcome when the fan blade rotates are balanced, and the maximization of the air-out efficiency is realized;
4. the air vent designed by the utility model is of a polygonal structure, so that the ventilation efficiency is indirectly optimized;
5. the utility model has the advantages that the downward convex groove formed on the fan blade mounting plate can effectively distinguish the front and back sides of the fan blade, thereby providing convenience for mounting;
6. the fan blade and the fan blade mounting plate of the utility model are vertically connected, so that the fan blade can be maximally contacted with air when rotating, and larger wind power is provided;
7. the utility model discloses the quantity of well flabellum is preferred nine, for having higher air output in fact.
Description of the drawings:
fig. 1 is a first schematic structural diagram of the present invention;
FIG. 2 is a second schematic structural diagram of the present invention;
in the figure:
1-a rotating shaft mounting disc; 2-mounting holes; 3-a fan blade mounting plate; 31-a groove; 4-fan blades; 5-a vent; 51-long side; 52-short side; 53-arc edge; 6-annular retainer ring.
The specific implementation mode is as follows:
the invention will now be further described with reference to specific embodiments, see fig. 1 and 2:
the utility model provides a fan blade, includes pivot mounting disc 1, and the center of pivot mounting disc 1 is provided with mounting hole 2, the outside circumference shaping of pivot mounting disc 1 has a plurality of outside extension's flabellum mounting panel 3, and the below shaping of flabellum mounting panel 3 has downwardly extending's flabellum 4, through integrated into one piece, saves process time to adopt downwardly extending's mode, can the shaping more flabellums, provide bigger amount of wind.
Preferably, an annular retainer ring 6 is formed on the outer side of the fan blade mounting plate 3, and an air vent 5 is formed between the adjacent fan blade mounting plate 3 and the annular retainer ring 6.
It should be mentioned that the fan blade with the rotating shaft mounting plate 1, the fan blade mounting plate 3, the fan blades 4 and the annular retainer ring 6 can be formed in one step by injection molding, and if the fan blade is made of metal, the fan blade can be formed in one step by stamping.
Preferably, the size of vent 5 is the same with flabellum 4, makes the resistance that air output and flabellum overcome when rotating reach the balance, realizes the maximize of air-out efficiency.
Preferably, the vent 5 is composed of a long side 51, a short side 52 and an arc-shaped side 53, and the fan blade 4 is extended and formed downward from the long side 51.
It should be noted that, in the above-mentioned manner of stamping the fan blade, the short side and the arc side of the whole metal material can be cut in advance, and the fan blade 4 formed by pressing down along the long side 51 is the same size as the ventilation opening 5, and the processing is simple.
Preferably, a groove 31 protruding downwards is formed on the fan blade mounting plate 3. The formed groove 31 can be used for conveniently distinguishing the front side and the back side of installation in the installation process.
Preferably, flabellum 4 with flabellum mounting panel 3 is connected perpendicularly, rotates the in-process, because flabellum 4 perpendicular to flabellum mounting panel 3, flabellum 4 can furthest with the air contact, promoted the air output.
Preferably, the number of the fan blades 4 is nine.
The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so: all equivalent changes made according to the shape, structure and principle of the utility model are covered within the protection scope of the utility model.
