The fluid refers to airflow sucked from the outside by the suction cavity of the suction nozzle body, and as the vortex formed by the airflow in the suction cavity is stronger, the capacity of the airflow for carrying garbage from the outside into the suction cavity and the capacity for further discharging the garbage from the suction cavity to the garbage collection device are stronger, so that the garbage suction capacity of the suction nozzle is improved.
The flow directing structure may be of any suitable form as long as it cooperates with the suction cavity to direct the gas into a stronger vortex. For example, the flow directing structure may be part of a scroll structure. To facilitate full utilization of the suction chamber, it is preferred that the flow directing structure extends from the inlet 10 to the rear side of the nozzle body to divide the suction chamber into a first suction chamber and a second suction chamber, as shown in figure 2, the outlets comprising a first outlet 17 communicating with the first suction chamber and a second outlet 18 communicating with the second suction chamber.

As shown in fig. 2, after the gas and the garbage enter the nozzle body from the inlet 10, because the two flow guide surfaces are connected at an angle at a position close to the inlet 10, the fluid can enter the first suction cavity and the second suction cavity respectively along the two flow guide surfaces of the first flow guide part, and the second flow guide part 15 extends from the rear end of the flow guide surfaces to the rear side of the nozzle body, thereby dividing the suction cavity into the first suction cavity and the second suction cavity. With reference to the configuration shown in figure 1, the first outlet 17 and the second outlet 18 are connected to one end of a suction pipe 7, and the other end of the suction pipe 7 can be connected to a device for generating negative pressure, so as to discharge the fluid in the first suction chamber and the second suction chamber to a waste collection device via the suction pipe 7.
