Abstract
A stirring blade group structure comprises a stirring blade base and at least three groups of stirring blades attached to the stirring blade base. Each stirring blade group includes a stirring shaft, a lower stirring blade, and an upper stirring blade. The upper stirring blade and the lower stirring blade cross and are attached to one end of the stirring shaft. The upper stirring blade is U-shaped.

A stirring blade group structure, comprising:
- a stirring blade base;
- and
- at least three groups of stirring blades attached to the stirring blade base, each stirring blade group including:
- a stirring shaft;
- a lower stirring blade having a lower hole formed on the lower stirring blade through which the stirring shaft extends, each lower stirring blade including a first lower stirring segment and a second lower stirring segment symmetrically to each other with respect to a centerline of the stirring shaft, a line going through the first stirring segment and a line going through the second lower stirring segment forming a lower bending angle, wherein the lower bending angle of the lower stirring blade in one group is different than that of the lower stirring blade in any of another two groups, wherein the lower stirring blade in the one group further includes a first end segment extending from the first lower stirring segment and a second end segment extending from the second lower stirring segment, a line going through the first end segment and the first lower stirring segment forming an end-stirring segment angle, a line going through the second end segment and the second lower stirring segment forming the end-stirring segment angle,
- wherein the end-stirring segment angle of the lower stirring blade in the one group is different than that of the lower stirring blade in at least one of the another two groups;
- and
- an upper stirring blade having an upper hole formed on the upper stirring blade through which the stirring shaft extends, the upper stirring blade including a first upper stirring segment and a second upper stirring segment asymmetrically to each other with respect to the centerline of the stirring shaft, a line going through the first stirring segment and a line going through the stirring shaft forming a first upper stirring angle, a line going through the second stirring segment and the line going through the stirring shaft forming a second upper stirring angle, wherein the first upper stirring angle is different than the second upper stirring angle, and wherein the first upper stirring segment and the second upper stirring segment form a U-shape.

A stirring device, comprising:
- a drive unit, a transmission assembly coupled to the drive unit and a stirring blade group structure coupled to the transmission assembly, the transmission assembly configured to transmit power from the drive unit to the stirring blade group structure, the stirring blade group structure including:
- a stirring blade base;
- and
- at least three groups of stirring blades, each stirring blade group including:
- a stirring shaft;
- a lower stirring blade having a lower hole formed on the lower stirring blade through which the stirring shaft extends, each lower stirring blade including a first lower stirring segment and a second lower stirring segment symmetrically to each other with respect to a centerline of the stirring shaft, a line going through the first stirring segment and a line going through the second lower stirring segment forming a bending angle, wherein the lower bending angle of the lower stirring blade in one group is different than that of the lower stirring blade in any of another two groups, wherein the lower stirring blade in the one group further includes a first end segment extending from the first lower stirring segment and a second end segment extending from the second lower stirring segment, a line going through the first end segment and the first lower stirring segment forming an end-stirring segment angle, a line going through the second end segment and the second lower stirring segment forming the end-stirring segment angle,
- wherein the end-stirring segment angle of the lower stirring blade in the one group is different than that of the lower stirring blade in at least one of the another two groups;
- and
- an upper stirring blade having an upper hole formed on the upper stirring blade through which the stirring shaft extends, the upper stirring blade including a first upper stirring segment and a second upper stirring segment asymmetrically to each other with respect to the centerline of the stirring shaft, a line going through the first stirring segment and a line going through the stirring shaft forming a first upper angle, a line going through the second stirring segment and the line going through the stirring shaft forming a second upper angle, wherein the first upper angle is different than the second upper angle, and wherein the first upper stirring blade and the second upper stirring segment form a U-shape.
