In some embodiments, the junction of the guide vane 200 and the bottom plate 100 forms a connecting section 240, the connecting section 240 is curved, and the guide vane 200 is formed by extending the connecting section 240, so that the guide vane 200 is curved along the fluid flow direction, and is more adaptive to the fluid flow than a linear arrangement, and simultaneously controls the radial flow direction and the circumferential flow direction of the fluid.
In some of these embodiments, the flow guide surface 210 is optionally curved. The curved flow guide surface 210 makes the flow guide surface 210 more linear in the flow direction, so that the fluid is more smoothly transited, noise generated by collision is reduced, and flow control is realized. Referring to fig. 4 to 9, the flow guiding surface 210 is a single arc, and it can be understood that the flow guiding surface 210 may also be formed by connecting multiple arcs with different radians, multiple straight lines with different inclination directions, or a combination of multiple straight lines and arcs.

For the convenience of fluid flowing along the circumferential direction, the bottom surface to the top surface 230 of the spoiler rib 500 are generally set to be the inclined surface or the convex arc-shaped surface, so that the residence time of the fluid on the spoiler rib 500 is reduced, the fluid can continuously flow along the original direction, namely, the fluid flows along the circumferential direction, and therefore the flowing direction is not changed too much. It should be noted that the guide surface 210 is perpendicular to the bottom plate 100 to control the fluid flowing along the guide channel, so that more effective area can be reserved to enable the fluid to flow along the guide surface 210, that is, the fluid is controlled to flow in the radial direction, the circumferential flow speed of the fluid is reduced, the acoustic radiation of the fluid near the cup bottom is controlled, and the whipping noise is reduced.
Referring to fig. 4, 8 and 10, in some embodiments thereof, the top surface 230 of the vane 200 is a plane parallel to the base plate 100, and the flow guiding surface 210 extends from the connecting section 240 to the top surface 230 of the vane 200. The top surface 230 of the guide vane 200 is configured as a plane, and compared to an arc-shaped surface or other convex surfaces, more effective area can be reserved to enable the fluid to flow along the guide channel, that is, the guide surface 210 has a larger area, and the extension of the guide surface 210 from the connecting section 240 to the top surface 230 of the guide vane 200 is also for enabling the guide surface 210 to have a larger area, thereby improving the guide efficiency. It is understood that the top surface 230 and the flow guiding surface 210 may be rounded or chamfered for transition, and the flow guiding surface 210 may also be a portion between the bottom plate 100 and the top surface 230 of the guide vane 200, i.e. the flow guiding surface 210 may be at least one or a combination thereof disposed in an upper, middle or lower portion of the guide vane 200.
In some of these embodiments, the top surface 230 of stator 200 can also be provided with cutting tooth or cutting edge, and cutting tooth and cutting edge can improve stator 200's cutting ability to improve food processor's whipping performance, reduce the residue rate after the cooking, promote the effect of cooking.
Referring to fig. 4 to 11, the guide vanes 200 are uniformly distributed along the circumferential direction of the bottom plate 100, so that the stress of the flow guide structure 10 is more balanced, and the flow guide is more stable. It will be appreciated that, because the base plate 100 can be fixed to the bottom of the cup, the uneven arrangement of the guide vanes 200 can also achieve a certain noise reduction effect.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
