The motor and the fan of the dust collector are the core components of the dust collector, and the quality of the performance of the motor and the fan of the dust collector plays a decisive role in the product quality of the dust collector. Because the dust removing capacity of the dust collector is required to be higher and higher, the required fan output power of the dust collector is gradually increased.

At present, the defects of the existing processing technology and the influence of material strength can not meet the strength requirement, so that the centrifugal impeller rotating at high speed is damaged when the 500-plus-700W brushless motor dust collector is used and subjected to safety tests, and meanwhile, the blades are directly embedded on the wall surface of the flow channel, and the flow channel is somewhat or even directly damaged, so that the research and design of a high-strength impeller structure has very important significance for the high-power brushless motor dust collector. In recent years, the improvement of the strength of the centrifugal impeller in China mainly adopts the modes of replacing materials, reducing the rotating speed, increasing the diameter, increasing the outlet angle of the impeller and the like, although the strength is improved, the performance of the fan is reduced, and the using effect is poor.

Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 to 2, the utility model discloses an embodiment of high power dust catcher motor fan, including impeller 1, impeller 1 is including lower blade 3, well blade 4 and the last blade 2 that sets gradually, go up blade 2 with the coaxial setting of lower blade 3, lower blade 3 outwards extends and forms limit 5 of bending, 5 combinations in limit 5 of bending form bending structure, bending structure's diameter ratio 1-3mm more of lower blade 3's diameter, bending structure's bending angle is 0-60 degrees.

When the impeller 1 is used, the strength test shows that the impeller 1 and the lower blade 3 damaged by the strength test are deformed into upward convex arc sheets from the original plane, the impeller 1 in the existing dust collector motor mainly adopts aluminum materials, the upper, middle and lower sheets of the impeller 1 are respectively subjected to die sinking and stamping, and finally, the upper, middle and lower sheets are assembled and then formed by stamping. Since the mass-produced centrifugal impeller 1 has the upper blade 2, the middle blade 4, and the lower blade 3 connected together by the rivet points, the strength of the rivet points determines the strength of the impeller 1. In the process of high-speed rotation of the impeller 1, the centrifugal force of the impeller 1 gradually increases and is constant at last, when the impeller 1 does not change, the riveting point only needs to overcome the radial shear stress of the centrifugal force on the riveting point, but once the lower blade 3 deforms, the centrifugal force becomes a combination of two forces, namely, the force along the deformation direction and the force perpendicular to the deformation direction are combined, so that the strength of the riveting point is determined by the force perpendicular to the deformation direction, the number of influencing factors is mainly two, and one is the deformation angle of the impeller; the second is the cross section, namely the volume after the riveting point is riveted and deformed, through research, the increase of the riveting point certainly has the effect of improving the strength, but has great influence on the performance of the whole impeller, so in the aspect of structural improvement, the prior consideration is not suitable, therefore, the bending edge 5 is added on the lower blade 3, the distance between the center of mass of the whole impeller and a fixed fulcrum, namely the center of the lower blade 3 can be reduced, the bending moment can be reduced, the strength of the impeller is improved, the diameter of the bending structure is 1-3mm larger than the diameter of the lower blade 3, the bending angle of the bending structure is 0-60 degrees, and through experimental analysis, the using effect of the bending edge 5 under the condition is the best.

The impeller 1 is made of aluminum materials, the cost is extremely low, the using effect is good, the upper blade 2, the middle blade 4 and the lower blade 3 are punched through die sinking and are connected together through riveting points, the structure is stable, one side, close to the upper blade 2, of the lower blade 3 is a plane, the upper blade 2 is an upward protruding arc sheet, and the upper blade 2 is provided with air guide holes 6.
