The invention relate to cleaning nozzles. A suction nozzle structure and a cleaning apparatus are disclose, wherein the suction nozzle structure comprises a suction nozzle body (1), A suction pipe (2)and a nozzle (3), the suction nozzle body (1) comprises a top plate (11), the top plate (11) is provided with an air inlet (12) and an air outlet (13), The suction pipe (2) is communicated with the air outlet (13) on the outer side of the top plate (11), the nozzle (3) is communicated with the air inlet (12) on the inner side of the top plate (11), the nozzle (3) is arranged on the front side ofthe suction pipe (2), and the lower end of the nozzle (3) is inclined backward with respect to the upper end of the nozzle (3). Through the technical proposal, the nozzle can form jet airflow in the suction chamber, so that garbage on the surface to be cleaned opposite to the suction chamber is blown up, the residence time of garbage in the suction chamber is prolonged, and the ability of garbagesuction of the suction nozzle structure is improved.
