Background technique

At present, the cross-sectional area of the suction pipe of the cleaning products on the market is mostly round or nearly rectangular. During the operation, the sewage goes up against the side wall of the suction pipe, and the air is also in the middle of the suction pipe. go. In order to ensure the intake area of the main motor, there is a certain size requirement for the cross-sectional area of the inlet pipe, which causes the flow rate of the air in the suction pipe to be further increased due to the limitation of the cross-sectional area. Therefore, when the sewage crawls to a certain height, the thrust provided by the airflow in the suction pipe is insufficient to offset the gravity of the sewage itself, and the sewage cannot be effectively sent to the recovery bin. At the same time, when the suction pipe works, the air flow on both sides of the suction pipe is required to transport the sewage and the resistance is high, and the flow velocity in the center of the suction pipe is upward due to the absence of the resistance, and the high flow rate is upward when the large flow liquid is encountered. It is very likely to cause turbulence in the pipe, which in turn affects the effect of the sewage sticking upwards.
