As a kind of enforceable mode, each axial-flow leaf 200 includes wheel hub 220 and multiple blades 230, Duo Geye
Piece 230 is circumferentially provided on along wheel hub 220 on wheel hub 220；
Multiple blades 230 are alternatively arranged, and air flow channel is formed between two neighboring blade 230, each axial-flow leaf 200
The direction of air flow channel and the direction of the air flow channel of adjacent axial-flow leaf 200 have angle；At least two axial-flow leafs 200
Air flow channel composition air passage 210.
Wherein, the blade 230 of multiple axial-flow leafs 200 can be straight blade (such as simple straight leaf shown in Fig. 2
Shape), can also be curved blade (such as complex-curved leaf shown in Fig. 1 a).Or in multiple axial-flow leafs 200, certain
A or some axial-flow leafs 200 use curved blade using straight blade 230, some or some axial-flow leaf 200 in addition
230, and the axial-flow leaf 200 using straight blade 230 can be handed over successively with the axial blade 230 using curved blade 230
It is alternately arranged in connecting shaft 100, it is of course also possible to not be to be alternately arranged successively.

Flow fan only includes two axial-flow leafs 200, and the air passage 210 that the combination of two such axial-flow leaf 200 is formed is fairly simple
(forming air passage of the tool there are one bending segment for two linear air flow channels), is similar to through type up and down, then the axial flow blower
Anti- static pressure ability it is just weaker, therefore just need to add an axial-flow leaf 200.But when rotating speed is very high, axial-flow leaf
200 anti-static pressure ability will improve, and there is no need to add an axial-flow leaf 200.
Certainly, if in two axial-flow leafs 200, one is simple leaf axial-flow leaf 200 as shown in Figure 2, separately

Design can weaken the number of blade and the leaf limitation to axial flow blower performance, when each axial-flow leaf 200 the number of blade and it is leaf not
Meanwhile the rotating speed of each axial-flow leaf 200 can obtain optimal air quantity and anti-static pressure ability as the variable adjusted.Certainly,
In other embodiments, each power source 240 can also drive each axial-flow leaf 200 with identical rotational speed respectively.
As a kind of enforceable mode, connecting shaft 100 includes the multiple shafts being mutually rotatablely connected, each power source
240 are connected with a rotating shaft transmission, and each shaft is connected with an axial-flow leaf 200.So, it can be achieved that each axis stream wind
Leaf 200 is with mutually different rotational speed.
Wherein, there are many modes that multiple shafts rotatably connect, for example, multiple shafts are rotatably arranged in one
On a main shaft, then multiple shafts can be relatively rotated while formed by main shaft and be connected.For another example, multiple shafts can be arranged successively, and
It can relatively rotate.For another example, one end of each shaft is equipped with connecting pole, and connection column outer wall sets annular protrusion, and the other end
Connecting hole is equipped with, connecting hole inner wall sets annular groove, then the end that a shaft is equipped with connecting pole is inserted into another turn
The connecting hole of axis, it is achieved thereby that shaft and shaft are rotatably connected.

110 and second shaft 120 of first rotating shaft is included, first rotating shaft 110 is rotatably sleeved on outside the second shaft 120, and the second shaft
120 both ends protrude from first rotating shaft 110；
Two axial-flow leafs 200 are separately positioned on one end of first rotating shaft 110 and one end of the second shaft 120, and two
Axial-flow leaf 200 is respectively positioned on the same side of the middle section of connecting shaft 100；
Two power sources 240 are separately positioned on the other end of first rotating shaft 110 and the other end of the second shaft 120.So
