Embodiment
1-3 and technical scheme is further illustrated by embodiment below in conjunction with the accompanying drawings.
The air purifier of the present invention, including impeller assembly 5.As shown in Figures 1 to 3, impeller assembly 5 of the invention, including
Impeller body 51, impeller body 51 protrude upward and for motor to be contained in its internal boss 54 and some blades 53, leaf
Piece 53 is arranged on impeller body 51 and outwards centrifuges distribution around 54 periphery of boss, and the top of boss 54 is in cone, air-flow
Conical surface transition through boss 54 is between blade 53 and flowing out.
Specifically, boss 54 includes the cylindrical section positioned at lower end and the conical section positioned at upper end, and the top of conical section is half
Spherical, the bottom surface of conical section and the top surface of cylindrical section are adapted, and the junction of conical section and cylindrical section is to smoothly transit.
In the present embodiment, the hemispheric radius on conical section top is 7~8mm.For example, the top hemispherical of conical section
Radius can be 7mm, 7.1mm, 7.2mm, 7.3mm, 7.4mm, 7.5mm, 7.6mm, 7.7mm, 7.8mm, 7.9mm, 8mm.
In the present embodiment, a diameter of 35~45mm of cylindrical section.For example, the diameter of cylindrical section can be 35mm, 36mm,
37mm、38mm、39mm、40mm、41mm、42mm、43mm、44mm、45mm。
In the present embodiment, the top radius of conical section is 7.5mm, and the basal diameter of conical section is 40mm, conical section with
The junction of cylindrical section is smoothly transits, whole conical surface smooth transition, and guarantee leaks out smooth；Air inlet gradually expands, circle
The peak of cone section distance 6.6mm at air inlet area minimum, avoids conical section from influencing incoming air area.So set
Afterwards, influence of the raised head face to wind turbine inlet air can be effectively reduced, increases blade channel entrance air quantity, is reduced at air inlet
Sinuous flow, so as to improve fan efficiency.
As shown in Figure 1, 2, the edge that impeller assembly 5 of the invention is further included corresponding to impeller body 51 is arranged at impeller sheet
The mounting ring 52 of the top of body 51, blade 53 are connected between impeller body 51 and mounting ring 52.Two blades 53 of arbitrary neighborhood
The distance between air intake vent 55 is less than the distance between air outlet 56, air-flow from the conical surface transition of boss 54 to air intake vent 55 after from
Air outlet 56 flows out.In the present embodiment, spacing is left between one end of the close boss 54 of blade 53 and boss 54, both are not
Contact.
Further, blade 53 includes blade linkage section 531 and blade body 532, and blade linkage section 531 is away from boss 54
And mounting ring 52 is connected to, blade body 532 is close to boss 54 and is connected to mounting ring 52.In the present embodiment, blade connects
Section 531 is obliquely installed in the opposite direction with blade body 532, and blade linkage section 531 and the junction of blade body 532 form one
Angle, namely blade linkage section 531 form √ type structures with blade body 532.
The blade body 532 of the present invention is in curved arc shape, it is preferred that the bending direction of blade body 532 is towards the institute of boss 54
Side.Blade linkage section 531 is also in curved arc shape, and the bending direction of blade linkage section 531 and the bending of blade body 532
Direction is on the contrary, in the present embodiment, the overbending direction of blade linkage section 531 is in counter clockwise direction, the bending side of blade body 532
To in clockwise.The thickness of blade linkage section 531 is more than the thickness of blade body 532.
Based on said structure, the blade is using centrifugal, different from axial-flow type, the movement locus of its bending direction and gas
It is identical, thus comply with the flow direction of gas, and backward type blade be transmitted to air-flow absolute velocity it is also smaller than forward-type, air-flow with
The speed that end cap bumps against is also smaller；Spacing between two neighboring blade body is gradually widened from the inside to the outside, and expands ratio
Compared with mitigation, air-flow is also more unobstructed, and therefore, its energy loss is relatively low relative to forward-type, and then under the requirement for meeting noise
Improve the air output of air purifier.
Above in association with the specific embodiment technical principle that the invention has been described.These descriptions are intended merely to explain the present invention's
Principle, and limiting the scope of the invention cannot be construed in any way.Based on explanation herein, the technology of this area
Personnel would not require any inventive effort the other embodiments that can associate the present invention, these modes are fallen within
Within protection scope of the present invention.
