Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example one

Fig. 1 is a schematic structural diagram of a stirring assembly according to an embodiment of the present invention; fig. 2 is an exploded view of a stirring assembly according to an embodiment of the present invention; FIG. 3 is a cross-sectional view taken at A-A of FIG. 1; fig. 4 is a cross-sectional view at B-B in fig. 1.

As shown in fig. 1 to 4, the present embodiment provides a stirring assembly including a stirring main body 10 and an elastic coating sleeve 20. Specifically, the stirring body 10 includes a central shaft 11 and a stirring blade 12 connected to the central shaft 11. Illustratively, the number of the stirring vanes 12 may be one, two, three, four or more, and the central shaft 11 is connected to the rotation center of the stirring vanes 12. The central shaft 11 and the stirring blades 12 can be connected together through fasteners; or, the central shaft 11 and the stirring blades 12 can be connected together by welding or bonding; alternatively, the central shaft 11 and the stirring blades 12 may be an integral piece.

Further, the middle shaft 11 is used for connecting a driving component, for example, a non-circular connecting groove may be disposed at one end of the middle shaft 11, so that the middle shaft and an output shaft of the driving component are sleeved together, and the driving component can drive the stirring blade 12 to rotate and complete a stirring action by driving the middle shaft 11.
