Technical field
A kind of mute centrifugal blower of big flow of the utility model refers to a kind of centrifugal blower, has low noise and air quantity
Big advantage.
Background technology
Centrifugal blower is widely used in life, but existing fan noise is big, and wind flow is not big enough, and
And existing wind turbine has spiral helicine shell, thickness is also larger, in actual use, the more demanding occasion of some sizes
It cannot use, it is therefore necessary to design a kind of new product to meet actual use demand.
Invention content
The utility model has good using effect in view of this, providing a kind of mute centrifugal blower of big flow.
A kind of mute centrifugal blower of big flow is made of motor, impeller and the crust of weathering；Being provided in the crust of weathering can rotate
Impeller, axle center and the motor of impeller carry out be connected by power, and motor is fixedly mounted on the crust of weathering.
The crust of weathering is along the full symmetric round pie of the center line of air outlet or so（With traditional centrifugal blower volute
Using the difference of spiral of Archimedes spiral case）, the following table face closure of the crust of weathering, upper surface offers the air inlet for air inlet,
Air outlet is offered in the side of the crust of weathering；
The air inlet is circle.
The outer most edge cross section of the air outlet is round, ellipse or kidney-shaped, air outlet stretch out the crust of weathering and with by
Tapered small taper.
The taper α of the air outlet is 30 °（Taper is angle of the blowing mouth compared to crust of weathering bottom surface）.
The impeller has the blade of collection leaf dish and multi-disc equidimension, integrates leaf dish as disc-shaped, in the upper table of collection leaf dish
Face surrounds the center of circle, and equidistant arrangement has more blades.
The blade tip is further fixedly arranged on secondary collection leaf dish, and pair collection leaf dish is ring-type, the centre point of pair collection leaf dish with
Collect the coordinate of the center of circle of leaf dish in same axle center.
The blade is formed by three sections of flat sheet dog-ears, and three sections of sheet lengths of blade are from most inner side successively to extension
It is long, length ratio 1:1.5~2.5：3~4；Preferably 1:1.8~2.2:3.2~3.8；It is further preferably 1:2:3.5.
The width of the blade is gradually reduced outward by most inner side, and the bottom end of blade is plane, and top continuously decreases；Most
Ratio between the height and outermost height of inside is 1:0.5 ~ 0.9, preferably 1:0.75.
The blade quantity is 5 ~ 20, and preferably 8 ~ 15, be further preferably 9 ~ 12, most preferably 10.
The motor is fixedly mounted on the back side of the crust of weathering.
The plastic shell that the crust of weathering is integrally formed has structural strength height, the low feature of processing cost.
The impeller is compared to existing fan leaf, due to being provided with the fan blade of multiple protrusions in collection leaf dish, is turning
The rotation and cutting of high speed, and the air-flow that will be cut under the influence of centrifugal force can be effectively carried out when dynamic to the air-flow of sucking
The outer most edge to crust of weathering inner wall is got rid of, and is exported by the air outlet of taper, and due to being additionally provided with secondary collection leaf dish on the top of fan blade,
It can effectively prevent the air-flow of sucking from being thrown out of air inlet, invalid turbulent flow be formed, to improve the efficiency of blowing；And
Since collection leaf dish and secondary collection leaf dish pool together multi-disc fan blade in the application, a cake for having larger thickness is formd
Shape structure, compared to the prior art in common fan blade, structural strength will be higher by very much, be not easily formed shake at runtime
Quiver, to effectively reduce noise, and smoothness is high when due to operation, rotating speed can relative to existing equipment height, to
Improve discharge quantity of fan and noise want it is low go out it is very much, and it is also low to consume energy, and has good using effect.
The utility model is simple in structure, is skillfully constructed, is easy to use, and low noise, low energy consumption, thickness are low, and air output
Greatly, the use of all trades and professions can be suitble to, the hair-dryer being particularly suitable as on car washer uses.
