Self-suction stirrer

The utility model provides a self-suction stirrer which comprises a power device, a hollow shaft, a stirring paddle, an air inlet and an air outlet device, wherein an air transmission channel is formed in the hollow shaft, and the power device is in transmission connection with the hollow shaft through a shaft coupling; the stirring paddle is mounted at the end part of the hollow shaft, and the air inlet is formed in the hollow shaft; the air outlet device is arranged between the air inlet and the stirring paddle and can take rotate by taking the axis of the hollow shaft as a rotation center; an air outlet is formed in the air outlet device, and the air inlet is communicated with the air outlet of the air outlet device through the air transmission channel. The self-suction stirrer improves the original direct-insertion type air feeding mode, the weight of a stirring shaft is reduced, and transmission load is reduced. Bubbles entering into liquid are tiny and fill up a groove body, so that the use ratio of wind is greatly improved, a medium-pressure blower for supplying air in the current design is removed, and the operating cost of the blower and the material consumption of an air pipe and an air nozzle are reduced.
