A motor 201 is fixed to the top surface of the cover plate 101, and a rotating shaft 202 with a stepped shaft structure is fixed on the output shaft of the motor 201. A sleeve 203 is slidingly provided on the upper limit of the rotating shaft 202, and an impeller 204 is welded on the sleeve 203 in a linear array.

[0037] Among them, a spring 206 is sleeved on the rotating shaft 202, and the lower end of the spring 206 elastically contacts the step of the rotating shaft 202, and the upper end of the spring 206 elastically contacts the bottom end surface of the sleeve 203. The spring 206 is used to reset the sleeve 203 upward.

[0038] Among them, the bottom end surface of the cover plate 101 is welded with a protrusion 207 in a circular array, and the protrusion 207 is a hemispherical structure; the top surface of the uppermost impeller 204 is welded with a force rod 208, and the upper end of the force rod 208 is in elastic contact with the protrusion 207. During mixing, the motor 201 is controlled to rotate, and the motor 201 drives the rotating shaft 202, the sleeve 203 and the impeller 204 to rotate. During the rotation of the impeller 204, the liquid can be mixed. At the same time, under the extrusion of the protrusion 207, the force rod 208 and the impeller 204 reciprocate up and down. During the rotation of the impeller 204, the liquid can be better mixed through the up and down reciprocating movement of the impeller 204.

[0039] Among them, each impeller 204 is provided with through holes 205 in a circular array.
