Embodiment
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, pawl formula Wind Volume impeller, it includes wheel disc 1 and wheel cap 2, and blade 3, described leaf
Piece 3 includes the blade body 31 of arc, and the upper and lower ends of blade body 31 have a vertical component effect 32, right on the wheel disc 1 and wheel cap 2
Mounting hole 4 should be provided with, the vertical component effect 32 of the upper and lower ends of blade body 31 inserts in the mounting hole 4 that wheel disc and wheel cover respectively
And the surface of mounting hole 4 is exposed to, vertical component effect 32 bends and is attached to wheel disc or the surface of wheel cap, the vertical component effect at the both ends
The direction of bending is identical.
The utility model is fixedly connected after devising a kind of bending using vertical component effect with wheel disc and wheel cap, is that a kind of physics connects
The mode connect, high-temperature soldering need not be carried out in fixation procedure, reduce the possibility of deformable blade, further, this practicality is new
The direction that type is bent to vertical component effect is defined, and the directions of two bendings are thought simultaneously, the active force of wheel disc and wheel cap to blade
Direction it is identical, reduce the influence of precision that mismachining tolerance positions to blade, at the same decrease blade can in fixation procedure
Can caused by deform, when both are in opposite direction, wheel cap and wheel disc are in opposite direction to the active force of blade, and blade there may be
The problem of torsional deformation, while also the mismachining tolerance of mounting hole is amplified, there is larger shadow to the positioning precision of blade
Ring.
Further, the thickness of described blade 3 is 0.5 ± 0.02mm, and blade described in the utility model uses aluminium
Plate compacting forms, and the thickness of above-mentioned blade reduces the quality of blade, then dropped as far as possible under the intensity requirement for meeting air output
The low quality of whole impeller, is advantageous to the work of impeller.
Further, described mounting hole 4 is in arcuation waist hole, using the design of arcuation waist hole, is easy to the installation of blade,
The requirement to processing mold is also reduced simultaneously, and production cost is controlled.
Further, described blade body 31 has the first arc sections 311, the second arc sections 312 and three-arc portion
313 are formed, and the radiuses of first arc sections is 7.5mm, and the radiuses of the second arc sections is 7.56mm, the radius in three-arc portion
For 7.6mm, blade body of the present utility model uses the structure design of variable diameters, increases the air output of whole impeller.
In summary, the utility model has the advantages that：
The utility model is improved the connected mode of blade and wheel disc and wheel cap, using physics mode make blade with
Wheel disc and wheel cap link together, the problem of avoiding deformable blade caused by being welded to connect, meanwhile, vertical component effect in the utility model
The direction of bending is identical, caused by avoiding overbending direction opposite the problem of blade lean.
Further, the utility model is improved the structure of blade, and blade uses multistage different-diameter arc sections
Form, increase the intake of impeller.
The utility model is not limited to described embodiment, those skilled in the art do not depart from it is of the present utility model
In the i.e. open scope of spirit, it can still make some amendments or change, therefore rights protection scope of the present utility model is with claims
