Summary of the Invention
[0003] In view of the above defects existing in the prior art, the utility model provides a dust suction air duct system of a floor washing machine, and the specific technical solutions are as follows:
[0004] A dust suction air duct system of a floor washing machine includes a housing assembly, a dust suction nozzle, a filter screen, a sewage pipe, a sewage tank pipe, and an exhaust pipe. The dust suction nozzle is installed inside the housing assembly, and a dust suction port is formed by an opening below the dust suction nozzle. A first dust suction air duct is arranged inside the dust suction nozzle, and a second dust suction air duct is arranged inside the housing assembly. The first dust suction air duct communicates with the second dust suction air duct. A transition passage and a filtering chamber are arranged inside the housing assembly. The second dust suction air duct communicates with the filtering chamber through the transition passage. The filter screen is installed inside the filtering chamber. The filtering chamber communicates with the sewage pipe, and the sewage pipe communicates with the sewage tank pipe. The sewage tank pipe is installed inside the sewage tank. A blower is installed above the sewage tank, and an exhaust pipe is installed behind the blower. The blower drives the gas inside the sewage tank to be discharged from the exhaust pipe.
[0005] As a preferred solution of the utility model, when the blower is started, the gas flow direction is successively the dust suction port, the first dust suction air duct, the second dust suction air duct, the transition passage, the filtering chamber, the sewage pipe, the sewage tank pipe, and the exhaust pipe.
[0006] As a preferred solution of the utility model, the dust suction nozzle communicates with the second dust suction air duct through a sealant joint.
[0007] As a preferred solution of the utility model, the filter screen is provided with a plurality of mesh holes.
[0008] As a preferred solution of the utility model, a filter cotton is arranged between the blower and the sewage tank.
[0009] As a preferred solution of the utility model, the upper opening of the sewage tank pipe is higher than the bottom surface of the sewage tank.
[0010] Beneficial effects: When the fan starts, hair and large particles of garbage are sucked in turn from the suction port, pass through the dust suction port, the first dust suction air duct, the second dust suction air duct, and the transition channel to reach the filter chamber. The large particles of dirt are intercepted by the filter screen, and the small particles of dirt enter the sewage tank pipeline through the sewage pipeline, so that the dry garbage is sucked into the filter chamber through the suction port before contacting the roller, and the roller mopping can clean the ground more deeply.

[0017] The following further describes the detailed embodiments of the present utility model in conjunction with the drawings:
[0018] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.
[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0020] As Figures 1 to 6As shown in the figure, a dust suction air duct system of a floor washer includes a housing assembly 1, a dust suction nozzle 2, a filter screen 3, a sewage pipe 4, a sewage tank pipe 5, and an exhaust pipe 6. The dust suction nozzle 2 is installed inside the housing assembly 1. An opening is formed at the bottom of the dust suction nozzle 2 to form a dust suction port 7. A first dust suction air duct 8 is provided inside the dust suction nozzle 2. A second dust suction air duct 9 is provided inside the housing assembly 1. The first dust suction air duct 8 communicates with the second dust suction air duct 9. A transition channel 10 and a filter chamber 11 are provided inside the housing assembly 1. The second dust suction air duct 9 communicates with the filter chamber 11 through the transition channel 10. The filter screen 3 is installed inside the filter chamber 11. The filter chamber 11 communicates with the sewage pipe 4. The sewage pipe 4 communicates with the sewage tank pipe 5. The sewage tank pipe 5 is installed inside the sewage tank 12. A blower 13 is installed above the sewage tank 12. The exhaust pipe 6 is installed behind the blower 13. The blower 13 drives the gas in the sewage tank to be discharged from the exhaust pipe 6 to generate negative pressure. The gas flow direction is successively the dust suction port 7, the first dust suction air duct 8, the second dust suction air duct 9, the transition channel 10, the filter chamber 11, the sewage pipe 4, the sewage tank pipe 5, and the exhaust pipe 6, so as to complete the collection of garbage and dirt.
