Abstract
The utility model belongs to fan art, is for the edge side leakage of existing fan blade, the little and a kind of edge side leakage free providing of monsoon intensity, the nested fan blade of high wind-force intensity are provided, it comprises central rotating shaft, three groups of internal fan blades, at least two external spiral blades, isolating ring, strut and cylinder, three groups of internal fan blades are distributed on the exterior circumferential of central rotating shaft, external spiral blade is distributed on the inner side of cylinder, and external spiral blade and cylinder are affixed, the inner upper end of helical blade and interior lower end are all connected with isolating ring outside, the utility model is by three groups of internal fan blades, external spiral blade is designed to closely be connected inseparable with cylinder and isolating ring, external spiral blade and cylinder are done the as a whole air motion of spinning in cylinder that is more conducive to, being unlikely to air leaks hunting from blade edge, on central rotating shaft, equally distributed three groups of internal fan blades, by coordinating external spiral blade to strengthen the spiral motion of air, strengthen flowing velocity and the efficiency of air simultaneously.
Description
Technical field
The utility model belongs to fan technical field, particularly a kind of blade of New Type of Fan.
Background technique
Blade and the shell of existing conventional fan are separated from each other, and blade rotates with respect to shell, and this structure can make air leak hunting from blade edge; And conventional fan blade only has one group, the air entering in blade is less, and the intensity of the wind blowing out is less, and noise is larger, is difficult to meet the demand in market.
Model utility content
The purpose of this utility model be for the air side leakage of existing fan blade edge, go out monsoon intensity little, only have one group of blade and an a kind of edge side leakage free providing, the nested fan blade of high wind-force intensity.
The utility model is achieved by the following technical solution:
Novel fan vane, comprise central rotating shaft, three groups of internal fan blades, at least two external spiral blades, isolating ring, strut and cylinders, three groups of described internal fan blades are distributed on the exterior circumferential of central rotating shaft, described external spiral blade is evenly distributed on the inner side of cylinder, and external spiral blade and cylinder are affixed, inner upper end and interior lower end at described external spiral blade are all connected with isolating ring, between two isolating rings and central rotating shaft, by equally distributed three struts, fix.
The diameter of described cylinder is more than or equal to 5 centimetres, and cylinder heights is more than or equal to 5 centimetres.
Described internal fan blade is three groups, and the pitch of external spiral blade is more than or equal to 5 centimetres, and thickness is more than or equal to 0.1 centimetre, and width is more than or equal to 1 centimetre.
The beneficial effects of the utility model: the utility model is designed to closely be connected inseparable by three groups of internal fan blades, external spiral blade and cylinder and isolating ring, external spiral blade and cylinder are done the as a whole air motion of spinning in cylinder that is more conducive to, and are unlikely to air and leak hunting from blade edge; On central rotating shaft, equally distributed three groups of internal fan blades, by coordinating external spiral blade to strengthen the spiral motion of air, strengthen flowing velocity and the efficiency of air simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Novel fan vane as shown in Figure 1, it should be noted that, comprise central rotating shaft 1, three groups of internal fan blades 2, at least two external spiral blades 3, isolating ring 4, strut 5 and cylinders 6, three groups of described internal fan blades 2 are distributed on the exterior circumferential of central rotating shaft 1, described external spiral blade 3 is evenly distributed on the inner side of cylinder 6, and external spiral blade 3 is affixed with cylinder 6, inner upper end and interior lower end at described external spiral blade 3 are all connected with between isolating ring 4, two isolating rings 4 and central rotating shaft 1 fixing by equally distributed three struts 5.The diameter of described cylinder is more than or equal to 5 centimetres, and cylinder heights is more than or equal to 5 centimetres.The pitch of described inside and outside two groups of helical blades is more than or equal to 5 centimetres, and thickness is more than or equal to 0.1 centimetre, and width is more than or equal to 1 centimetre.
When fan high speed rotating, the air that the enters cylinder motion of spinning under the drive of two kinds of nested blades.Because spiral motion is circular movement and straight-line synthetic, therefore, the air that enters fan is actually and moves in a circle and straight line motion simultaneously.Circular movement makes the air that enters fan do centrifugal motion around axle center; Straight line motion makes the air that enters fan be taken out of fan, and fan air pressure inside is reduced.Therefore, outside air just constantly enters fan with very high speed, forms high-speed eddy.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope, those skilled in that art's simple change and replacement are all within protection domain of the present utility model.
