Abstract
The utility model belongs to fan art, relates to a kind of Novel fan vane, 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 double helix fan blade of high strength wind-force are provided; It comprises central rotating shaft, at least two internal helical blades, at least two external spiral blades, isolating ring, strut and cylinders, described internal helical blades is 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, the utility model is designed to closely be connected inseparable by inside and outside two groups of helical blades 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, and are unlikely to air and leak hunting from blade edge; On central rotating shaft, equally distributed internal helical blades, by coordinating external spiral blade to strengthen the spiral motion of air, strengthens 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
Helical 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 helical blade fan only has one group of blade, enter air in blade less, 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 double helix fan blade of high strength wind-force.
The utility model is achieved by the following technical solution:
Novel fan vane, comprise central rotating shaft, at least two internal helical blades, at least two external spiral blades, isolating ring, strut and cylinders, described internal helical blades is 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, fix by equally distributed three struts.
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 two groups of vane sheets of inside and outside spiral shell 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 inside and outside two groups of helical blades 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, and are unlikely to air and leak hunting from blade edge; On central rotating shaft, equally distributed internal helical blades, by coordinating external spiral blade to strengthen the spiral motion of air, strengthens flowing velocity and the efficiency of air simultaneously.
Brief description of the drawings
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, at least two internal helical blades 2, at least two external spiral blades 3, isolating ring 4, strut 5 and cylinders 6, described internal helical blades 2 is 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.
In the time of fan high speed rotating, the air that the enters cylinder motion of spinning under the drive of double helix blade.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, and the motion of spinning under the drive of two groups of helical blades 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.
