Because the top of blade housing 3 is equipped with the pressure release hole 4 that runs through, liquid can supply negative pressure zone automatically to discharge from pressure release hole 4, reduce the vortex formation in the cup, and then avoid blade housing 3 to be adsorbed in the container bottom, the laborsaving operation is of value to and improves work efficiency, and user experience is better.

The following describes in detail the specific structure of each part of the stirring device according to the embodiment of the present invention with reference to the drawings.

The top end of the stirring rod 1 may be provided with a driving means, or a connecting mechanism for connecting with an external driving means may be provided at the top end of the stirring rod 1, as shown in fig. 4. A cutter support 7 is arranged in the stirring rod 1, an oil-containing bearing 8 is arranged in the cutter support 7, and the cutter shaft 2 penetrates through the oil-containing bearing 8 and the cutter support 7 so as to rotatably connect the cutter shaft 2 in the stirring rod 1, as shown in fig. 2.

In some embodiments, the blade cover 3 may be cylindrical, the bottom end of the cylindrical shape is open, the top surface of the cylindrical shape is fixedly connected with the stirring rod 1, and the pressure relief hole 4 is arranged on the top surface of the cylindrical shape, so that the shape can ensure that the pressure relief hole 4 is positioned at the uppermost part of the blade cover 3, and a negative pressure area is prevented from being formed in the cavity of the cover. Of course, the blade housing 3 may also have a hemispherical, conical or other shape.

In the specific implementation process, the number of the pressure relief holes 4 is multiple, and the pressure relief holes 4 are annularly arranged around the stirring rod 1. For example, join in fig. 4, puddler 1 fixed connection can be in the top surface center department of cylinder, and the quantity of pressure release hole 4 can be four, and four pressure release holes 4 can be the annular around puddler 1 and evenly lay, so can make the liquid stream of cover intracavity evenly flow out through a plurality of pressure release holes 4, can make agitating unit atress balanced at each angle, are of value to improving this agitating unit's stability.
