As shown in Figures 2 and 3, the axial flow blower that one embodiment of the invention provides, including：Connecting shaft 100 and at least two
Axial-flow leaf 200, at least two axial-flow leafs 200 are parallel to each other；Connecting shaft 100 is connected with least two axial-flow leafs 200, is used
In driving at least two axial-flow leafs 200 coaxial and rotate in the same direction；
Along the axially arranged of connecting shaft 100, at least two axial-flow leafs 200 are formed along even at least two axial-flow leafs 200
The axial direction of spindle 100 is in the air channel 210 with least one bending segment (as shown in the continuous arrow in Fig. 2).
Wherein, each axial-flow leaf 200 can be separate that connecting shaft 100 is connected with each axial-flow leaf 200,
Connecting shaft 100 is rotated to drive each axial-flow leaf 200 to rotate.Certainly, in other embodiments, each axial-flow leaf 200
Can be connected with each other integrally, connecting shaft 100 is connected with one of axial-flow leaf 200, and connecting shaft 100, which rotates, also can
Each axial-flow leaf 200 is driven to rotate.
And air channel 210, when it has a bending segment, its shape can be with substantially v-shaped or U-shaped, when it has two
During individual or three and the above bending segment, its shape can be it is substantially S-shaped or substantially Z-shape, either

Also can be different, it can specifically be designed according to being actually needed.
The axial flow blower of the present embodiment, when the air stream outlet static pressure of blower fan is bigger, such as air duct, air channel block, air-flow
When not smooth, because air channel 210 has bending segment, the air-flow of blower fan discharge is not easy to flow back along the air channel 210 with bending segment,
Therefore not interfering with air-flow enters blower fan, so as to improve the anti-static pressure ability of axial flow blower.
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 wheel hub 220 along wheel hub 220；
Multiple blades 230 are spaced, 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 channel 210.
Wherein, the blade 230 of multiple axial-flow leafs 200 can be straight blade (such as the simple straight leaf shown in Fig. 2
Shape), can also be curved blade (such as complex-curved leaf shown in Fig. 1).Or in multiple axial-flow leafs 200, certain
Individual 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
Alternately it is arranged in connecting shaft 100, it is of course also possible to not be to be alternately arranged successively.
In each axial-flow leaf 200, air flow channel is formed between adjacent two blades 230, when an axial-flow leaf 200
Blade 230 when being straight blade, the substantially rectilinear shape of air flow channel of formation；When the blade 230 of an axial-flow leaf 200

During 100 axially stacking setting, the air flow channel direction per two adjacent axial-flow leafs 200 has angle, two air streams
The junction section in road forms a foregoing bending segment, and multiple axial-flow leafs 200 can form the wind with multiple bending segments
Road 210.
The number of blade of multiple axial-flow leafs 200 can be it is consistent, can also be different.When the number of blade is more, anti-static pressure
Ability is relatively good, but air quantity is smaller, anti-static pressure ability when the number of blade is few, but air quantity is preferable, can be based on unit during specific design
Requirement and environment selected.
As a kind of enforceable mode, the number of blade of each axial-flow leaf 200 of axial flow blower is consistent.
Or the blade shape of each axial-flow leaf 200 of axial flow blower is consistent.
Or the number of blade of each axial-flow leaf 200 of axial flow blower is consistent and blade shape is also consistent.
Further, the number of the axial-flow leaf 200 of axial flow blower can by the specific leaf of each axial-flow leaf 200 and
The parameters such as the rotating speed of axial-flow leaf 200 determine.For example, axial-flow leaf 200 as shown in Figure 2 is leaf relatively simple, it is assumed that axle
Flow fan only includes two axial-flow leafs 200, the air channel 210 that the combination of two such axial-flow leaf 200 is formed it is fairly simple (for
Two linear air flow channels form the air channel with a bending segment), it is similar to through type up and down, then the axial flow blower is anti-
Static pressure ability is just weaker, therefore just needs 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 avoid the need for adding 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
One is complex-curved leaf axial-flow leaf 200 as shown in Figure 1, then the air channel that the combination of two such axial-flow leaf 200 is formed
210 shape matchings distort so that the anti-static pressure ability of axial flow blower will not weaken.Thus, the leaf and axle stream of axial-flow leaf 200
The number of fan blade 200, or the leaf combination of axial-flow leaf 200 determine air channel form, in order to improve anti-static pressure ability, axle stream
The number of the axial-flow leaf 200 of blower fan must be according to leaf reasonable selection.

Different axial-flow leafs 200 rotate, and realize that the classification to air-flow accelerates, can greatly improve air velocity, lift the wind of unit
Amount.
Wherein, each power source 240 can control each axial-flow leaf 200 respectively with mutually different rotational speed, so
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 of regulation.Certainly,
In other embodiments, each power source 240 can also drive each axial-flow leaf 200 respectively with identical rotational speed.
As a kind of enforceable mode, connecting shaft 100 includes the multiple rotating shafts being mutually rotatablely connected, each power source
240 are connected with a rotating shaft transmission, and each rotating shaft is connected with an axial-flow leaf 200.So, each axle stream wind can be achieved
Leaf 200 is with mutually different rotational speed.
Wherein, the mode that multiple rotating shafts rotatably connect have it is a variety of, for example, multiple rotating shafts are rotatably arranged in one
On individual main shaft, then multiple rotating shafts can be relatively rotated while formed by main shaft and be connected.And for example, multiple rotating shafts can be arranged successively, and
It can relatively rotate.For another example, one end of each rotating 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 inwall sets annular groove, then the end that a rotating shaft is provided with connecting pole is inserted into another turn
The connecting hole of axle, it is achieved thereby that rotating shaft and rotating shaft are rotatably connected.
Referring to Fig. 3, Fig. 4 and Fig. 5, illustrate so that axial flow blower has two axial-flow leafs 200 as an example.
As a kind of enforceable mode, axial-flow leaf 200 is two, and power source 240 is also two；Connecting shaft 100 is wrapped
The rotating shaft 120 of first rotating shaft 110 and second is included, first rotating shaft 110 is rotatably sleeved on outside the second rotating shaft 120, and the second rotating 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 rotating 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 rotating shaft 120.So
Set, the gap between two axial-flow leafs 200 can be made smaller, make the air channel 210 to be formed relatively more continuous, while so setting makes
The structure for obtaining axial flow blower is more compact.
The axial flow blower of the embodiment of the present invention, not only anti-static pressure ability effectively improve, and due to multiple axial-flow leafs,
It can be driven respectively using multiple power sources, so as to greatly promote the air quantity of unit.
