Description

360 ° of annular air supply electric fans

The utility model relates to electric fan.

A few days ago, though the application of air-conditioning and ceiling fan is very general, stand fan and desk fan class because its mobility, on market, still have can not be replaced the status.

As everyone knows, stand fan and desk type electric fan class are since the city of torturing sb. during interrogation, and only tube shape is ever-changing, but the structural type of its most basic flabellum remains the same from beginning to end, and promptly are approximately " plane ".The wind that the rotation of this " plane " flabellum produces has very strong directionality.Thereby bring very big restriction to use.Appearing at of head oscillating structure enlarged wind direction to a certain extent, but its maximum wind direction also has only 90 °.Simultaneously, because the existence of commutation position " dead angle " in the swing process causes wind-force inhomogeneous, bring discomfort to the user.Moreover, during the broiling summer, " swing " itself also made us having the fidgets.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and 360 ° of annular air supply electric fans of a kind of nothing " swing " are provided.

The purpose of this utility model is achieved through the following technical solutions:

Structural feature of the present utility model is the flabellum shape, and described flabellum is to be pedestal with the solid of rotation, and flabellum is presented the wind heliconid at the surface of revolution of solid of rotation, and flabellum is the air draught volute casing in the upper/lower terminal portion of solid of rotation; Its running shaft is the flabellum rotating shaft.

The utility model has been realized 360 ° of annular air supplies of electric fan with specific flabellum shape.Compared with the prior art, the qualification of the utility model in use directionless, do not have swing, wind-force is even, easy to use comfortable.Its novelty rational in infrastructure has thoroughly changed traditional form.Have very strong ornamental.

Embodiment:

Referring to Fig. 1, flabellum 1 is to be pedestal with solid of rotation 2, and flabellum 1 is presented the wind heliconid at the surface of revolution of solid of rotation 2, and flabellum 1 is the air draught volute casing in the upper/lower terminal portion of solid of rotation 2.Running shaft is flabellum rotating shaft 4.

In order to improve intensity, as shown in Figure 1, can be provided with dividing plate 3 at the middle part of flabellum 1 as stiffening rib.

Referring to Fig. 2, in the rotary course of flabellum, air-flow sucks from the upper/lower terminal air draught volute casing place of flabellum 1, quickens operation along the air channel that is formed by flabellum and solid of rotation to the dividing plate direction, and the place is thrown out of at dividing plate, forms wind.Because the annular of flabellum is arranged, the wind of formation also is annular.

Flabellum 1 in the present embodiment is at least two leaves.

Referring to Fig. 3, flabellum 1 is for being distributed on the trilobed structure of solid of rotation 2 peripheries.

Referring to Fig. 4, flabellum 1 also can be four impeller structures that are distributed on solid of rotation 2 peripheries.

Referring to Fig. 5, flabellum 1 can also be six impeller structures that are distributed on solid of rotation 2 peripheries etc.The quantity of blade can be decided according to the size of electric fan itself.

Referring to Fig. 6, present embodiment adopts spherical guard shield 5.Concrete enforcement can adopt two semiglobe snappings to form.Guard shield 5 can be fixed form as shown in figure 10, also can adopt as Fig. 7, Fig. 8 and rotatable structure shown in Figure 9.

Referring to Fig. 7, the bearing 6 that is used to support flabellum rotating shaft 4 is fixedly installed on the corresponding position of guard shield 5.In guard shield 5 inboards, the aerofoil 7 of angle adjustable is installed, aerofoil 7 promptly drives guard shield 5 rotations after the wind-force that is subjected to from flabellum, by adjust aerofoil 7 towards, changing the stressed size of aerofoil 7, thereby change the rotational velocity of guard shield 5.

Referring to Fig. 8, adopt the friction transmission.In the axis hole of rotating shaft 4, embolism 8 is set, and has rubber pad 9 to be pressed on the axle head of rotating shaft 4.The adjustment of embolism 8 compaction degrees can change the rotational velocity of guard shield 5.

Referring to Fig. 9, adopt the spider gear transmission that constitutes by central gear 10, intermediate gear 11 and internal-gear 12.Wherein, the wheel shaft of central gear 10 connects firmly the axle head in rotating shaft 4, and internal-gear 12 is fixedly installed on guard shield 5 corresponding positions.

Referring to Figure 10, adopt fixed guard shield 5, between guard shield 5 and flabellum rotating shaft 4, be sliding fit.

Referring to Figure 11, in order to make wind-force and to more natural, soft, in the inboard of guard shield 5, be provided with adjustable perfect square to wind-guiding loose-leaf board 14.There is connecting rod 15 to connect between the every loose-leaf board, and regulating handle 16 is arranged.

Support 13 forms of the present utility model can be varied, Square seat bracket 13 as shown in figure 12, and round seat support 13 as shown in figure 13, curved support 13 as shown in figure 14, elephant support 13 as shown in figure 15, and sea dog support 13 as shown in figure 16 or the like.

Referring to Figure 17, because the utility model is an annular air supply, do not limit position and direction in putting, as shown in figure 16, be placed in indoor central authorities.
