Abstract

The invention discloses a combined impeller. At least one impeller is arranged in an annular seat body, wherein the annular seat body is provided with a guide surface and is also provided with at least one annular body hole group, the annular body hole group comprises a plurality of concave clamping grooves and a concave annular body hole, and each clamping groove is communicated with the annularbody hole and the guide surface; and the impeller is provided with an annular body which is embedded into the annular body hole of the annular seat body, a plurality of blades encircle the periphery of the annular body, reinforcing sheets for connecting the annular body and the blades are arranged between the inner edges of the blades and the periphery of the annular body, the reinforcing sheets are correspondingly embedded into the clamping grooves, the inner edges of the blades and the guide surface have the same shape and are matched, and air passages are formed between the two adjacent blades and in a section formed by the annular seat body. Through the design, the weak sections formed between the annular body and the blades can be eliminated, so the impeller is not easy to deform, andaccurate positioning and combination between the impeller and the annular seat body are favorable.

Description

technical field [0001] The invention relates to a combined impeller, in particular to a combined impeller which overcomes the interference of mold release by using a combined method, increases the strength of the impeller component, prevents deformation, and precisely positions to improve product quality. Background technique [0002] Please refer to Chinese Patent No. ZL01268180.6 "Combined Cooling Fan" for existing cooling fans (please refer to Figure 11 ), the combined cooling fan 4 includes a lower fan body 41 and an upper fan body 42, the lower fan body 41 has a body 411 whose top surface protrudes into a cone shape, and a sleeve shaft 412 protrudes from the center of the top surface of the body 411, A plurality of lower blades 413 protrude from the outer periphery of the main body 411, and the top surface of the main body 411 extends outward from the periphery of the sleeve shaft 412 to have a number of locking grooves 414 corresponding to the lower blades 413.
