The one end of the feeding shaft 120 is connected with the motor 130, and the other end of the feeding shaft 120 is connected with the extraction tank 210, and the feeding shaft 120 is at a certain angle relative to the ground, so as to drive the centella asiatica powder entering from the inlet into the extraction tank 210.
