Description
【Technical field】
The utility model is related to a kind of flabellum, also relates to a kind of centrifugal fan with the flabellum.
【Background technology】
It is known that flabellum is the important composition composition of ceiling fan, it is driven by motor rotates, to produce the part of wind,
Therefore, the design of flabellum is an important ring in the global design of ceiling fan, and the design of flabellum is made with the hydrodynamics of Bernoulli Jacob
For its Main Basis.
It is desirable that adjustment and design by carrying out structure to flabellum, in the running of ceiling fan, produce more
Many downward wind-force, and gather the wind-force produced in flabellum rotary course is greater concentration of downwards, while by air gas
The influence of stream allows flabellum in rotary course, secondarily promotes the rotation of flabellum, allows the rotation of flabellum more to save power, this
Sample can just reach the purpose for improving ceiling fan operational efficiency.
In view of the above-mentioned problems, we have proposed a solution.
【Utility model content】
The purpose of this utility model is to be to overcome the deficiencies in the prior art to gather wind-force more greatly there is provided one kind,
More Wind Volume is produced, and the flabellum of flabellum motive force can be saved；Additionally provide a kind of centrifugal fan simultaneously.
In order to solve above-mentioned technical problem, the utility model uses following technical proposals：
A kind of flabellum, it includes installation butt, and the vane region stretched out from installation butt；Described vane region
Include the leaf exhibition portion on the inside of it and the pushing part on the outside of it according to the direction of rotation of flabellum；Described leaf exhibition portion is one
Sheet tiltler, and its incline direction is sloped downwardly setting from inside facing outward；Bending is connected to leaf exhibition downwards for the pushing part
The outside in portion.
In to a kind of above-mentioned improvement project of flabellum, bending angle between the pushing part and leaf exhibition portion for 90 °~
180°。
In to a kind of above-mentioned improvement project of flabellum, the cross section in the leaf exhibition portion is the upward arch shape of radian.
In to a kind of above-mentioned improvement project of flabellum, described vane region is prolonged to it from installing head end that butt is connected
The extension tail end stretched is in arc-shaped.
In to a kind of above-mentioned improvement project of flabellum, provided with decoration lateral expansion portion on the outside of the pushing part.
A kind of centrifugal fan, includes suspension rod, leaf dish, motor, also includes some above-mentioned flabellums, all fans
Leaf is distributed along leaf dish even circumferential and the installation butt of each flabellum is all connected in leaf dish.
In to a kind of above-mentioned improvement project of centrifugal fan, one is passed through between the installation butt and leaf dish of described flabellum
Rotating shaft is connected.
Compared with prior art, the beneficial effects of the utility model are：The utility model passes through the leaf exhibition portion in vane region
Outside sets pushing part, will bend connection between pushing part and leaf exhibition portion, and one causes the vane region in pushing part and leaf exhibition portion
Formed below to gather region, so after flabellum rotation, air draught more will intensively be gathered below flabellum, produce more
Many downward wind-force, improves the operating efficiency of flabellum, and two to form a side away from the side of its direction of rotation in flabellum
Plate, so after flabellum rotates, the air draught behind flabellum direction of rotation is driven, to flabellum away from its rotation
Play a motive force in the side for turning direction so that pushing part turns into the stress surface for bearing air draught effect, increases flabellum
To the lifting surface area of air draught motive force, the auxiliary pushing power rotated to flabellum is further increased, so as to save flabellum
Power supply required for rotation, further increasing the operating efficiency of flabellum.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：

【Embodiment】
A kind of flabellum 60, as shown in the embodiment one and embodiment two shown in Fig. 1,2,5,6, it includes installation butt
10, and the vane region 20 stretched out from installation butt 10；Described vane region 20 is from installing the head end that butt 10 is connected
Extension tail end to its extension is in arc-shaped；Described vane region 20 includes on the inside of it according to the direction of rotation of flabellum 60
Leaf exhibition portion 21 and the pushing part 22 on the outside of it；Described leaf exhibition portion 21 is a sheet tiltler, and its incline direction is from interior
