Abstract

The utility model relates to a ceiling fan comprising a motor and blades, wherein, the blades are shaped like a propeller, a connection plate is arranged on the rotor of the motor, the roots of the blades are matched with the outline of the connection plate, a lug boss is arranged on the inner side of the root of each blade, and a blade fixing structure is arranged between the connection plate and the lug boss. To install the blades, all that is needed is to place the roots of the blades in the corresponding positions on the connection plate and lock the roots up using the fixing structures. The ceiling fan has the advantages of more reasonable structure, convenient installation and easy day-to-day assembly, disassembly and transport. Moreover, due to the fact that the blades are installed on the connection plate of the rotor instead of being assembled through a blade rack, the chances of the blades being vibrated are reduced, thereby ensuring that the ceiling fan works more stably with lower noise. At the same time, due to the fact that the blades are shaped like the propeller and that the roots of all the blades basically conceal the entire motor and the connection plate thereon from vision, the ceiling fan enjoys attractive external appearance and 3D streamlined design, and can produce more natural and gentler breezes.

Description

Ceiling fan

[technical field]

The utility model relates to a kind of ceiling fan.

[background technique]

We know, ceiling fan mainly is made up of motor and several blade, wherein motor includes stator and rotor, present stage, each blade is to pass through stamping part---vane frame is connected to epitrochanterian, the vane frame two ends use screw to fixedly connected with root of blade with rotor respectively when mounted, this not only install loaded down with trivial details, operation is more, causes the cost of production height; And, easily cause blade swing when rotating, make ceiling fan work not too steady, when high speed rotating, can produce bigger noise.

[model utility content]

The purpose of this utility model is to be to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, easy for installation, working stability and noise is little, the ceiling fan of beautiful shape.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:

A kind of ceiling fan includes motor and blade, and wherein said blade is the oar shape in the shape of a spiral, on the rotor of described motor, be provided with land, described root of blade is corresponding with the land profile phase, is provided with boss in this root of blade inboard, is provided with the vanes fixed structure between described land and boss.

In the improvement project to above-mentioned ceiling fan, described land profile is circular; The boss of described root of blade and Qi Nei and this circle land are right mutually.

Land described in the improvement project of above-mentioned ceiling fan is being had upper and lower two, and boss has two-layer up and down.

In the improvement project to above-mentioned ceiling fan, described vanes fixed structure includes at least two pairs of attachment posts and jack and is tightened in screw on the attachment post, and described attachment post and jack are separately positioned on this land and this boss.

In the improvement project to above-mentioned ceiling fan, described vanes fixed structure includes at least two pairs of attachment posts and jack and is tightened in screw on the attachment post, and described attachment post and jack are separately positioned on this boss and this land.

Prior art is compared, the beneficial effects of the utility model are: when blade is installed, need only the corresponding position that root of blade is put into land, being locked with fixed structure gets final product again, its more reasonable structure, easy for installation all is very easy in daily dismounting, transportation; In addition, because blade is to be directly installed on the land of rotor, rather than install, can reduce the possibility that blade rocks like this, thereby make the work of ceiling fan more stable and noise is little by vane frame; Meanwhile, blade is the oar shape in the shape of a spiral, and the root of all blades basically with whole motor and on land coat, can't see motor and land in the external world, can make the beautiful shape of ceiling fan, three-dimensional streamline sense strong like this, the blowing effect is soft more naturally.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Fig. 2 is the worm's eye view of Fig. 1;

Fig. 3 is the utility model embodiment's a motor stereogram;

Fig. 4 is the utility model embodiment's a blade stereogram;

Fig. 5 is the utility model embodiment's an assembling schematic representation (with individual blade).

[embodiment]

The utility model is a kind of ceiling fan, and shown in Fig. 1,2,5, it includes motor 1 and several blades 2, and wherein said blade 2 is the oar shape in the shape of a spiral, can make whole ceiling fan profile more attractive in appearance like this, and the blowing effect is soft more naturally; Be provided with land 3 on the rotor of described motor 1, described blade 2 roots 21 are corresponding with the land profile phase, because land 3 appearance profiles are generally circle, at this moment root of blade 21 is curved; Be provided with boss 22 in these root of blade 21 inboards, between described land 3 and boss 22, be provided with vanes fixed structure 4.Land 3 generally is directly to be locked on rotor, when blade is installed, as long as root of blade is put into the corresponding position of land, be locked with fixed structure 4 again and get final product, as can be seen, more reasonable structure of the present utility model, easy for installation all is very easy in daily dismounting, transportation.In addition, because blade is to be directly installed on the land of rotor, rather than install, can reduce the possibility that blade rocks like this, thereby make the work of ceiling fan more stable and noise is little by vane frame; Meanwhile, the root of all blades (is arc at this) basically with whole motor and on land coat, can't see motor and land in the external world, can make the beautiful shape of ceiling fan, three-dimensional streamline sense strong like this.

In the present embodiment, as shown in Figure 3, land 3 appearance profiles are circular, and the boss 22 curved (as shown in Figure 4) of described blade 2 roots 21 and Qi Nei is promptly right mutually with this circle land.

Vanes fixed structure 4 can be different structure, in the present embodiment, it includes at least two pairs of attachment posts 41 and jack 42 and is tightened in screw 43 on the attachment post 41, at this three pairs of attachment posts and jack are arranged, and attachment post 41 and jack 42 are separately positioned on this land 3 and the boss 22, when mounted, and as shown in Figure 5, the attachment post 41 back covers that jack 42 on the boss 22 of blade is aimed on the lands 3 force up, and get final product with screw 43 lockings again.In the present embodiment, land 3 has upper and lower two, and boss also has two-layer up and down, and the installation that can make blade like this is safety more firmly, rotates more steady, common in lower floor attachment post and jack between just screw down.Certainly, attachment post 41 and jack 42 also can be separately positioned on boss and the land conversely.

Lampshade 5 auxiliary devices such as grade can also be set on ceiling fan.
