Description

A kind of dynamical flabellum component

Technical field

The utility model relates to fan apparatus field more particularly to a kind of dynamical flabellum components.

Background technique

Ceiling fan, which can be hung, blows on the ceiling for indoor environment, is that one kind is relieved summer heat better function, energy saving, and has both The product of decorative effect, it is very popular on the market.

The flabellum of ceiling fan drives rotation that surrounding air flowing can be allowed to generate wind by motor, in the current market often In the structure for the flabellum component seen, a tilt angle, the process of flabellum rotation are formed between flabellum main body and the rotary shaft of motor It is middle to push air-flow downwards, but since flabellum main body is a block piece plate, partial air can be along the surface of flabellum towards margin location Loss is set, causes the air quantity pushed downwards that can reduce, and then causes the efficiency of fan lower, and flabellum main body intensity is insufficient, It is easy to happen deformation, influences the stability of flabellum component outlet air.

In addition, flabellum component is made of the leaf fork and flabellum being detachably connected, leaf fork is connected on the rotation section of motor, is fanned Leaf directly passes through screw lock solid structure and is installed on leaf fork, to realize the transmission connection with motor；Such structure both increased The cost of flabellum component, but the production installation effectiveness for resulting in fan is lower, and in use, between flabellum and leaf fork Connection structure be easy to happen loosening, there are the flabellum risks isolated with leaf fork.

Utility model content

For overcome the deficiencies in the prior art, the utility model provides a kind of dynamical flabellum component.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of dynamical flabellum component is pitched including leaf and pitches the blade being connected with leaf, and the surface of the blade is downward Bending forms a fold line, and the both ends of the fold line extend respectively to blade close to rotation center one end and blade far from rotation Blade is divided into the first wind face and the second wind face by the two sides of the other end of the heart, the fold line, and first wind face and leaf are pitched Substantially maintain an equal level, forms the angle tilted down between the second wind face and the first wind face.

As preferred embodiments of the present invention, the fold line is overlapped with a wherein diagonal line for blade.

Further preferably, first wind face, fold line, between the second wind face cambered surface transition to form wind gathering space.

Further preferably, the leaf fork is formed with blade integrated punching.

Preferably, the leaf pitches the dowel that upper punch forming has at least one to extend along the length direction of blade.

Preferably, punch forming has V-type reinforcing rib between the leaf fork and blade, which is located at the connection The one end of muscle far from rotation center.

The beneficial effects of the utility model are: surface downward bending formation and leaf of the flabellum component of the above structure by blade The first substantially fair wind face of fork and opposite first wind inclined second wind face downwards, air-flow below blade is from first Wind face enters, and is then discharged diagonally downward along the second wind face by fold line, is conducive to increase what flabellum component was discharged downwards Air quantity；Further, first wind face, fold line, to form wind gathering space, air-flow is passing through for cambered surface transition between the second wind face The whirlpool that air-flow can be generated when the wind gathering space, the air-flow for avoiding the first wind face and the second wind face straight transitions and generating damage It loses, to further increase the air quantity that flabellum component is discharged downwards, improves the efficiency of fan.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples:

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

Utility model will be further described in detail below with reference to the attached drawings and specific embodiments, however, it is desirable to say Bright, the explanation to following implementation is schematically, not constitute the specific restriction to the utility model.

Referring to Fig.1, a kind of dynamical flabellum component, including leaf fork 1 and the blade 2 being connected with leaf fork 1, the blade 2 surface downward bending forms a fold line 3, the both ends of the fold line 3 extend respectively to blade close to rotation center one end and Blade 2 is divided into the first wind face 21 and the second wind face by the two sides of the other end of the blade far from rotation center, the fold line 3 22, first wind face 21 and leaf fork 1 substantially maintain an equal level, and form the folder tilted down between the second wind face 22 and the first wind face 21 Angle, herein, the angle that the opposite first wind face 21 in the second wind face 22 tilts down is about 4 °.The flabellum component of the above structure is by leaf The surface downward bending of piece 2 forms the first wind face 21 substantially fair with leaf fork 1 and opposite first wind face 21 tilts down the Two wind faces 22, the air-flow positioned at 2 lower section of blade enter from the first wind face 21, then incline along the second wind face 22 by fold line 3 It is discharged obliquely, is conducive to increase the air quantity that flabellum component is discharged downwards.

In the present embodiment, the fold line 3 is overlapped with a wherein diagonal line for blade 2, the first wind face 21 and second Wind face 22 all forms the shape of triangle.

First wind face 21, fold line 3, to form wind gathering space, air-flow is being passed through for cambered surface transition between the second wind face 22 The whirlpool that air-flow can be generated when crossing the wind gathering space avoids the first wind face 21 and 22 straight transitions of the second wind face and generates Windage loss improves the efficiency of fan to further increase the air quantity that flabellum component is discharged downwards.

In the present embodiment, the leaf fork 1 is formed with 2 integrated punching of blade, and leaf fork 1 forms energy with 2 integrated punching of blade It enough ensures that the intensity of flabellum component entirety, the process for reducing production assembly improve production efficiency, reduces the cost of flabellum component.

Preferably, the dowel 11 that punch forming has at least one to extend along the length direction of blade 2 on the leaf fork 1, In the present embodiment, as shown, the quantity of dowel 11 is set as three, three dowels 11 are distributed in leaf evenly and at intervals On fork 1, dowel ensure that the mechanical strength of leaf fork 1；Wherein, also punch forming has V-type to add between the leaf fork 1 and blade 2 Strengthening tendons 12, the V-type reinforcing rib 12 are located at the described one end of dowel 11 far from rotation center, and V-type reinforcing rib 12 ensure that leaf fork 1 With the stiffness and strength of 2 link position of blade.

The preferred embodiments of the present invention have been specifically described above, certainly, the utility model can also using with The different form of above embodiment, those skilled in the art are made without departing from the spirit of the present invention Equivalent transformation or corresponding modification, all should belong in the protection scope of the utility model.
