Abstract
A self-cleaning negative-pressure ejector at least comprises a suction chamber, a jet pipe and a flushing member. A side wall of the suction chamber has at least one suction port for communicating with a first fluid pipeline. An exit port of the jet pipe is disposed in the suction chamber and ejects a second fluid so that a negative pressure is generated in the suction chamber, a first fluid in the first fluid pipeline enters the suction chamber, and a first included angle is between a direction in which the first fluid being sucked into the suction chamber and an ejection direction of the second fluid. The flushing member optionally provides a third fluid to flush the suction chamber and/or the first fluid pipeline.
