In some embodiments, the ratio of the first radius R1 and the second radius R2 are R1/R2=1.25-1.75.Preferably,
The ratio of first radius R1 and the second radius R2 are 1.5.
It is appreciated that the first air guide ring 12 is bent to the direction far from axis Z, the area of air intake vent 122 is increased to permit
Perhaps more air enter air-ducting ring 10.Second air guide ring 14 is bent to the direction far from axis Z, and one increases air outlet
For 142 area so that air is easier to flow out air-ducting ring 10 from air outlet 142, two carry out air can be along the second air guide ring 14
Fusiform inner wall gradually mixed with outside air, the vortex that generates when reducing air outflow, and then reduce noise.
In some embodiments, axial-flow windwheel 20 and air-ducting ring 10 are coaxially disposed, axial-flow windwheel 20 and air-ducting ring 10
The distance between inner wall is 7-10 millimeters.
In this way, preventing air-ducting ring 10 in use from interfering with the rotation of axial-flow windwheel 20, while being produced by 20 edge of axial-flow windwheel
Raw air-flow can be wrapped up by air-ducting ring 10 to increase air output.
In a comparative experiments, compare under different voltages, the air-supply assembly 100 and control group of embodiment of the present invention
Air-supply assembly (the first air guide ring is identical as the crooked process radius of the second air guide ring, and axial-flow windwheel is not provided with baffle) noise
And air quantity, obtain experimental data as shown in Table 1.
Table 1:
It can be obtained from upper table, under identical driving voltage, air-supply assembly 100 and the control group of embodiment of the present invention
Air-supply assembly is compared, and also reduces noise while improving air quantity.
Fig. 5 and Fig. 6 are please referred to, the axial-flow windwheel 20 of embodiment of the present invention further includes wheel hub 24, and multiple blades 22 are arranged
In the side of wheel hub 24.
Blade 22 includes leaf leading edge 222 and leaf rear 224.Leaf leading edge 222 is formed in the windward side of blade 22, Ye Houyuan
224 are formed in the leeward end of blade 22.Leaf rear 224 forms jagged 25, and notch 25 extends to leaf leading edge 222.Baffle 30
It is correspondingly arranged with the position of notch 25.
Specifically, in some embodiments, multiple blades 22 are in the side of wheel hub 24 in circumferential equiangularly spaced setting.
In this way, the rotation of axial-flow windwheel 20 is more stable, and the fluctuation of 20 air output of axial-flow windwheel is smaller.
In actual use, blade 22 can be designed using curved sweep structure, when axial-flow windwheel 20 rotates, be in blade 22
The leaf leading edge 222 of windward side cut air, air is divided into two parts by blade 22, and the pressure face 221 of blade 22 is by air
Local pressure increase and by air toward air supply direction push.The face opposite with pressure face 221 is suction surface 223 on blade 22,
The local pressure of air is reduced and attracts air toward air supply direction by suction surface 223.The sky of pressure face 221 and suction surface 223
Gas mixes at leaf rear 224.
In embodiments of the present invention, baffle 30 is arranged on pressure face 221, and baffle 30 can be by pressure face 221
Air flow, to prevent blade 22 from deforming under the pressure of air.And baffle 30 prevents the air of pressure face 221 in Ye Houyuan
224 certain positions are excessively intensively mixed with the air of suction surface 223, are reduced the generation of vortex and then are reduced noise.
Notch 25 and the position of baffle 30 are correspondingly arranged, and notch 25 extends to the direction of leaf leading edge 222, so that part
The air of pressure face 221 mixes at notch 25 in advance with the air of suction surface 223, can reduce the vortex of generation.
In another comparative experiments, compare under different rotating speeds, 20 control group of axial-flow windwheel of embodiment of the present invention
Axial-flow windwheel (not set baffle and notch) noise, obtain experimental data as shown in Table 2.
Table 2:
It can be obtained from upper table, in the case where same rotational speed, axial-flow windwheel 20 and the control group of embodiment of the present invention
Axial-flow windwheel is compared, and can be reduced noisiness.
In certain certain embodiments, blade 22 includes the blade root 226 connecting with wheel hub 24 and the leaf far from wheel hub 24
The thickness edge of outer rim 227, blade 22 is gradually increased from leaf outer rim 227 to the direction of blade root 226.
In this way, improving the strength and stiffness of blade 22, increase the intrinsic frequency of blade 22 in order to avoid generating resonance, and can enhance
The diversion effect of blade 22 avoids leaf leading edge 222 from being vortexed.
In embodiments of the present invention, the junction of blade root 226 and wheel hub 24 is smooth excessively equipped with rounded corner, to increase leaf
The intensity that root 226 is connect with wheel hub 24 avoids the occurrence of stress concentration.
In some embodiments, Ye Houyuan 224 includes interior rear 2242 and outer rear 2244.Interior rear 2242 connects leaf
Root 226 and notch 25.Outer 2244 connection breach 25 of rear and leaf outer rim 227.
In this way, pressure face 221 can be mixed in interior rear 2242 and outer rear 2244 respectively with the air of suction surface 223, lead to
The different shape for crossing rear 2242 and outer rear 2244 in being arranged, can make pressure face 221 from the air of suction surface 223 with different
Gradient is mixed, to meet the different air-supply demand of axial-flow windwheel 20.
In embodiments of the present invention, Ye Qianyuan 222 is arc-shaped, and interior rear 2242 and outer rear 2244 are also in circular arc
Shape.
In some embodiments, the intersection point of leaf outer rim 227 and leaf rear 224 is leaf exterior point C, on baffle 30 near
The point of leaf leading edge 222 is front end 32, and baffle 30 is in leaf outer rim 227 along the side of front end 32 and the line of the center Z of wheel hub 24

Flow block 30 thickness and reinforce area 228 thickness ratio be 0.4-0.6, preferably 0.5.
In this way, baffle 30 has enough thickness effectively to shunt the air of pressure face 221 and increases blade 22
Intensity, while the thickness of baffle 30 is not too large, avoids influencing the stability that axial-flow windwheel 20 rotates.
It should be noted that the thickness for reinforcing area 228 can not be it is equal everywhere, such as in embodiment of the present invention
In, the thickness edge for reinforcing area 228 is gradually increased from leaf outer rim 227 to the direction of blade root 226, accordingly, the thickness of baffle 30
It may not be equal everywhere.
In some embodiments, baffle 30 in crescent and is convex to leaf leading edge 222.
In this way, air is gradually directed into the both sides of baffle 30, air and baffle 30 by the baffle 30 of crescent
It is less to collide the vortex generated, more effectively to shunt air and reduce noise.
In some embodiments, notch 25 is arc-shaped.
In this way, notch 25 is less prone to the point of stress concentration, blade 22 is avoided to crack at notch 25, and in notch 25
Place, the air of pressure face 221 are gradually mixed with the air of suction surface 223, reduce the generation of vortex.
