[0025] When the defoaming agent enters the one end of the main body 1 from the inlet pipe 9, it will slide along the obliquely arranged sliding pipe 11 to the other end of the main body 1, in this process, the sliding pipe 11 not only plays a role in guiding the flow of the defoaming agent, but also uniformly distributes the sliding holes 12 at the bottom end, so that the defoaming agent is scattered into the cutting fluid in a uniform manner, which not only ensures that the defoaming agent can quickly cover every corner of the cutting fluid, but also greatly increases the contact area between the defoaming agent and the cutting fluid, thereby accelerating the reaction speed between the two.

[0028] The difference in diameter between the gear disc 3 and the driving gear 5 forms a speed reduction mechanism, which can make the gear disc 3 rotate at a relatively slow and stable speed under the drive of the driving gear 5, avoid the stirring speed being too fast, and the cutting fluid being subjected to too strong shear force, which not only accelerates the oxidation and deterioration of the cutting fluid, but also may produce additional foam due to the violent disturbance of the liquid surface, thereby weakening the effect of the defoaming agent and affecting the final defoaming effect, the speed reduction mechanism enables the stirring blades 7 to stir the cutting fluid at a moderate and uniform speed, which not only avoids the problems that may be caused by the too fast flow rate of the cutting fluid, but also ensures that all components in the cutting fluid can be fully mixed, thereby providing favorable conditions for the full contact and reaction between the defoaming agent and the cutting fluid.
