The invention discloses a suction
nozzle assembly, and the
assembly comprises a suction
nozzle body; a shell is arranged on the suction
nozzle body, an inclined side wall is arranged on the shell, a dust collection cavity is formed by the suction nozzle body and the shell, an air inlet is formed in the bottom face of the suction nozzle body, and an air outlet is formed in the shell;
airflow enters from the air inlet, flows through the dust collection chamber and is discharged from the air outlet, so the
airflow flowing through the dust collection chamber is uniformly distributed. The invention further discloses a cleaning
robot. The cleaning
robot comprises the suction nozzle
assembly. According to the suction nozzle assembly, the height from the air outlet to the ground is reduced, the average air speed in the dust collection cavity is increased, vortex
airflow can be generated, the entrainment effect is enhanced, and therefore, the
suction force to the ground and the negative
pressure level are improved, the
suction force below the air outlet is enhanced, and the dust particle conveying capacity is enhanced; transition areas from the two sides to the suction nozzle body are enlarged, so the
suction force level is more balanced, and dust particle leakage caused by weak suction force is reduced.
