and a fluid suction structure 3 including a fluid inlet disposed between the first fluid outlet and the second fluid outlet 211 for sucking the third fluid to remove the foreign matter.
The first fluid structure 1 conveys a first fluid to a part to be cleaned of a part to be cleaned so that foreign matters at the part to be cleaned can flow along with the first fluid, the second fluid structure 2 provides a second fluid, the first fluid changes the flow direction to form a third fluid, the problem that the first fluid forms a vortex at a right-angled turn of the part to be cleaned so as to cause poor foreign matter removal is prevented, and the fluid suction structure 3 provides suction force so that the third fluid completely enters the fluid suction structure 3 to sufficiently remove the foreign matters on the part to be cleaned.
The arrows in fig. 2 show the flow direction of the first fluid, the second fluid and the third fluid.
The coanda effect is the tendency of a fluid (water or air) to follow a convex object surface instead of moving away from the original direction of flow. When there is surface friction (also called fluid viscosity) between the fluid and the surface of the object over which it flows, the fluid follows the surface of the object as long as the curvature is not large.
In the cleaning device in the embodiment, the third fluid flows along the surfaces of the second fluid structure 2 and the fluid suction structure 3 to enter the fluid inlet by utilizing the coanda effect, and foreign matters on the component to be cleaned enter the fluid inlet along with the third fluid, so that the foreign matters are prevented from remaining on the component to be cleaned.
