Preferably, described first vane group 2 and described second vane group 3 form along the axis centre cross section of described impeller shaft 1 and arrange axisymmetrically.This is a kind of preferred structure and mode of execution, can not only ensure like this to realize Bidirectional outlet air when vane rotary, two vane group produce force and moment equal and opposite in direction on impeller shaft, direction is contrary, offset, play the effect of extra additional force and moment when reducing rotation suffered by impeller shaft.
Preferably, described first vane group 2 and described second vane group 3 are separately positioned on the position near axial different end face of described impeller shaft 1.Described impeller shaft comprises left end and right-hand member particularly, preferably the first impeller sets is arranged on the position near left end, the second impeller shaft is arranged on the position near right-hand member.The region in the middle of two vane group can be made so large as much as possible, ensure that air intake region large as far as possible, thus effectively increase the flowing of air-flow, and then add air output.
Preferably, multiple described first blade comprises the first identical blade of at least 3 sizes (be preferably 4, as shown in Figure 1-2), multiple described first blade is all arranged on the same cross section of described impeller shaft 1.Adopt the identical blade of size that air-out speed and air output and air-out region can be made more even, it is guide and then formation air-out the order of air-flow to ensure can be formed when rotated that multiple blade is arranged on the same cross section of impeller shaft.
Preferably, multiple described second blade comprises second blade identical with multiple described first blade number (be preferably 4, as shown in Figure 1-2), multiple described second blade is also all arranged on the same cross section of described impeller shaft 1.Can ensure that the air output of two different direction is all identical with air-out speed so as much as possible, achieve the effect of even air-out, and blade is arranged on same cross section and can ensures to form the order guiding to air-flow and then formation air-out when rotated, by the second vane group number of blade being set to identically with the first vane group number two vane group can also be made to produce force and moment equal and opposite in direction on impeller shaft, direction is contrary, plays the effect of extra additional force and moment when reducing to rotate suffered by impeller shaft as far as possible.
Preferably, multiple described first blade is evenly arranged along the circumferencial direction of impeller shaft 1.Effectively can ensure that the first vane group realizes air-out equably like this, avoid air-flow and spatially guide the situation of the uneven air-out of uneven generation to occur in diverse location place.
Preferably, multiple described second blade is also evenly arranged along the circumferencial direction of impeller shaft 1.Effectively can ensure that the second vane group realizes and the rightabout air-out equably of the first vane group like this, avoid air-flow and spatially guide the situation of the uneven air-out of uneven generation to occur in diverse location place.
Preferably, the axle center of described impeller shaft 1 is provided with the axis hole 4 that axial direction extends.Can effectively motor shaft be stretched into wherein by this axis hole, the final effect rotarily driving impeller shaft rotation realized by motor shaft.The through hole that preferably can be disposed through further, also can be arranged to blind hole.
Preferably, the interior sidewall surface of described axis hole 4 is provided with the limit structure (not shown) in circumferential direction.Effectively can carry out circumferential direction to the motor shaft inserting this axis hole by this limit structure and carry out position-limiting action, make motor shaft this motor shaft can be driven to be rotated by this limit structure when rotated, and then reach the effect of air-out.Further preferably this limit structure can be arranged to the structure of the such as keyway commonly used.
The utility model also provides a kind of fan or air-conditioning, and it comprises aforesaid axial-flow blower.The Bidirectional outlet air (i.e. two different direction axial air-out simultaneously) of axial-flow leaf can be realized by these two vane group by comprising the aforementioned axial-flow blower with two vane group, make to sweep demeanour to enclose and expand original 2 times to, effectively improve the situation that original axial-flow leaf air-out direction is single, increase and sweep wind angular range, 360 degree of omnibearing air-out can be realized, improve travelling comfort.
Preferably, also comprise motor, described motor comprises motor shaft, and when having the axis hole on axle center when described impeller shaft, described motor shaft is connected with described impeller shaft through described axis hole.
Impeller shaft and motor shaft match, and by the rotation of electrical power rear motor axle, pass to impeller shaft, impeller shaft being rotated, by rotating, affecting wind field, realize the movement of air towards fixed-direction, for fan or air-conditioning provide the power of rotation, realize air-out effect.
Preferably, when described impeller shaft has limit structure, described motor shaft is provided with the cooperating structure matched with the limit structure on described axis hole madial wall, makes it possible to be rotated by the rotating shaft of motor shaft impeller.Further preferably this cooperating structure can be arranged to the structures such as the such as flat key commonly used.
With reference to Fig. 2, describe the working principle when fan with this axial-flow blower or air-conditioning work below: when after electrical power, motor shaft can rotate, thus impeller rotating shaft rotates counterclockwise, at this moment in figure, the vane group in left side will outwards air draft, air-out on the left of realizing.Because left and right sides vane group is all on same blade shaft, so right side vane group also can be rotated, and due to right side leaf-group structure and left side vane group symmetrical, so right side vane group will air draft to the right, realize two-way simultaneous air-out.
The all outwards air draft of the fan blade left and right sides, the partial air in the middle of the vane group of the left and right sides will be made thin, and air pressure reduces, air natural and right meeting is assembled to centre, with supplementary air, thus middle can continuous air intake.Thus realize air intake in the middle of fan blade, the effect of left and right sides Bidirectional outlet air.
This axial-flow blower can be applied on multiple rotating mechanism, realizes Bidirectional outlet air.Especially can be used on above electric fan, enable the people be in both direction enjoy blowing, not only travelling comfort is good simultaneously, and can save the cost of an electric fan, increases economic efficiency, kills two birds with one stone.
Those skilled in the art will readily understand, under the prerequisite of not conflicting, above-mentioned each advantageous manner freely can combine, superpose.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
