The air flow channels in the existing sewage collection box are mostly arranged smoothly, so that the sewage pumping efficiency of the sewage collection box can be improved due to the fact that the sewage pumping air flow velocity in the sewage collection box is higher. However, the garbage collected by the cleaning device is generally mixed with sewage, the sewage water vapor is carried in the air flow discharged from the air outlet of the sewage collection box by the sewage pumping air flow flowing at high speed, and then the sewage water vapor is easy to accumulate in a subsequent air duct in the base station to generate mildewing and generate peculiar smell, or is easy to enter a fan of the base station to influence the service life of the fan. In view of the above problems, the present application proposes a sewage collection tank 100.

Referring to fig. 1 to 10, in the embodiment of the present application, the sewage collection tank 100 includes a first collection tank 10 and a second collection tank 30, a solid-liquid separation chamber 11 is formed in the first collection tank 10, the first collection tank 10 is provided with a sewage inlet 13 communicating with the solid-liquid separation chamber 11, and the solid-liquid separation chamber 11 is used for performing solid-liquid separation on a solid-liquid mixture; the second collecting box 30 is formed with a containing cavity 311 communicated with the solid-liquid separation cavity 11, the containing cavity 311 is used for collecting liquid separated by the solid-liquid separation cavity 11, the second collecting box 30 is provided with a first airflow channel 313, a second airflow channel 3315 and an air outlet 3311, the first airflow channel 313 is communicated with the containing cavity 311 and is bent to be communicated with the second airflow channel 3315, and the air outlet 3311 is communicated with the second airflow channel 3315 and is arranged on one side of the second airflow channel 3315.

It will be appreciated that the sewage collection tank 100 may be applied to a base station which may be formed with a docking chamber for docking a cleaning device (also referred to as a floor sweeping robot or a floor washing machine, etc.), so that the base station may provide clean water for cleaning to the cleaning device, clean cleaning tools of the cleaning device within the docking chamber, and recycle and temporary store garbage collected by the cleaning device. When the base station recovers the garbage collected by the cleaning device, the sewage suction pipeline of the base station can be accurately connected to the main machine sewage collection cavity of the cleaning device for storing the garbage after the cleaning device is stopped in the butt joint cavity, so that the sewage inlet 13 of the sewage collection box 100 arranged at the base station can be communicated with the main machine sewage collection cavity of the cleaning device through the sewage suction pipeline, at the moment, a fan of the base station is started, a sewage suction flow which flows through the sewage collection box 100 from the main machine sewage collection cavity and then flows into the fan can be formed, the flow speed of the sewage suction flow flowing into the sewage collection box 100 in the main machine sewage collection cavity is high, a strong negative pressure effect can be formed between the sewage inlet 13 and the main machine sewage collection cavity of the cleaning device, and the garbage in the main machine sewage collection cavity of the cleaning device can be well extracted and enters the solid-liquid separation cavity 11 of the first collection box 10 of the sewage collection box 100 through the sewage inlet 13. At this time, the solid garbage can be temporarily stored in the first collecting box 10 under the action of the solid-liquid separation cavity 11, and the liquid garbage passes through the first collecting box 10 and is collected in the accommodating cavity 311 of the second collecting box 30, so that the base station can effectively collect the garbage in the main machine dirt collecting cavity, and the purpose of recycling and temporarily storing is achieved.

In the process of recycling the garbage of the cleaning device by the base station, the sewage suction airflow sequentially passes through the main machine sewage collecting cavity of the cleaning device, the solid-liquid separation cavity 11 of the first collecting box 10 and the accommodating cavity 311 of the second collecting box 30, and then enters the air outlet 3311 on the second collecting box 30 to discharge the sewage collecting box 100 to flow back to the fan of the base station (refer to fig. 3 and 10, the dotted line with arrows in fig. 3 and 10 is the trend of the air path of the sewage suction airflow in the sewage collecting box 100), at this time, when the sewage suction airflow flowing at high speed and the liquid garbage enter the accommodating cavity 311 together from the solid-liquid separation cavity 11, part of the liquid garbage is easy to form sewage vapor under the action of the high-speed sewage suction airflow to be mixed into the sewage suction airflow, and flow along with the sewage suction airflow towards the fan of the base station. By arranging the first airflow channel 313 and the second airflow channel 3315 in the second collecting box 30, which are communicated with the accommodating cavity 311, and bending the first airflow channel 313 to be communicated with the second airflow channel 3315, the sewage pumping airflow needs to be bent in the first airflow channel 313 to flow into the second airflow channel 3315, which is beneficial to speed reduction of the sewage pumping airflow, at the moment, due to the fact that the weight of the sewage water vapor is large, the sewage water vapor is easy to be subjected to inertia effect after the flow rate of the sewage pumping airflow is reduced, and cannot be bent well to flow into the second airflow channel 3315, and then part of the sewage water vapor is blocked to be stored on the inner wall of the first airflow channel 313, and is gradually collected and refluxed into the accommodating cavity 311 under the action of gravity. Meanwhile, by arranging the air outlet 3311 communicated with the second air flow channel 3315 at one side of the second air flow channel 3315, the sewage pumping air flow needs to be bent when flowing into the air outlet 3311 from one side of the second air flow channel 3315 in the second air flow channel 3315 so as to be discharged out of the sewage collecting box 100, and then the sewage pumping air flow can be slowed down again, at the moment, residual sewage and water vapor in the sewage pumping air flow is easy to be retained on the inner wall of the second air flow channel 3315 under the inertia effect so as not to be bent well and enter the air outlet 3311, and is gradually collected and refluxed into the accommodating cavity 311 under the gravity effect. Through the arrangement, the sewage suction airflow can be bent and slowed down in the process of discharging the sewage collection box 100, so that the mixed sewage vapor in the sewage suction airflow can be blocked in the first airflow channel 313 and the second airflow channel 3315 and gradually collected and returned into the accommodating cavity 311 under the action of gravity, the sewage vapor carried in the sewage suction airflow discharged from the sewage collection box 100 through the air outlet 3311 is effectively reduced, the problem that the sewage vapor is collected and accumulated in a subsequent air channel of a base station fan to cause mildew in the subsequent air channel to generate peculiar smell is avoided, the garbage collected by the temporary storage cleaning device can be well and completely recovered by the sewage collection box 100, and the practicability and reliability of the sewage collection box 100 are further improved.

According to the technical scheme of the application, the first collecting tank 10 and the second collecting tank 30 are arranged in the sewage collecting tank 100, so that the solid-liquid mixture can enter the solid-liquid separation cavity 11 from the sewage inlet 13 of the first collecting tank 10 by using suction airflow, the solid-liquid mixture can be subjected to solid-liquid separation in the solid-liquid separation cavity 11, solids are reserved in the solid-liquid separation cavity 11, and liquid flows into the accommodating cavity 311 of the second collecting tank 30. By providing the first air flow channel 313 and the second air flow channel 3315 which are communicated with each other on the second collecting tank 30 and making the first air flow channel 313 communicate with the accommodating chamber 311, the suction air flow which enters the accommodating chamber 311 from the solid-liquid separation chamber 11 can flow through the first air flow channel 313 and the second air flow channel 3315 in sequence and be discharged from the air outlet holes 3311 which are communicated with the second air flow channel 3315, thereby realizing the recovery and temporary storage function of the sewage collecting tank 100. The first airflow channel 313 is bent and communicated with the second airflow channel 3315, and the air outlet holes 3311 are formed in one side of the second airflow channel 3315, so that the suction airflow can be bent in the first airflow channel 313 and flows into the second airflow channel 3315, and the suction airflow can be bent in the second airflow channel 3315 and flows out of the air outlet holes 3311 from one side of the second airflow channel 3315, so that the flow speed of the airflow can be effectively reduced by bending the suction airflow at two places, the water vapor carried in the airflow is reduced, and the water vapor carried in the airflow is easily and inertly thrown on the inner walls of the first airflow channel 313 and the second airflow channel 3315 when the airflow is bent and flows, thereby effectively reducing the water vapor carried in the suction airflow discharged from the sewage collecting box 100 through the air outlet holes 3311, reducing the odor generated in a base station and ensuring the normal operation of the base station, and improving the practicability of cleaning equipment.

Further, referring to fig. 8 to 11, in an embodiment of the present application, the second collecting box 30 is provided with two first air flow channels 313, the two first air flow channels 313 are respectively bent to communicate with two ends of the second air flow channel 3315, and the air outlet 3311 is provided between the two ends of the second air flow channel 3315.

At this time, when the two sewage pumping air flows in the second air flow channel 3315 to the air outlet 3311, the two sewage pumping air flows can mutually impact and reduce the speed, and flow out from the air outlet 3311, and the sewage water vapor mixed in the two sewage pumping air flows collide with each other due to the action of inertia and are thrown onto the inner wall of the channel of the second air flow channel 3315, so that the sewage water vapor carried in the sewage pumping water flow can be better blocked and trapped in the sewage collecting box 100, the sewage water vapor carried in the sewage pumping air flow discharged out of the sewage collecting box 100 through the air outlet 3311 is further reduced, and the practicability of the sewage collecting box 100 is improved. Second, by providing two first air flow channels 313 in the second collecting tank 30, the air outlet efficiency of the sewage collecting tank 100 can be further improved.

Meanwhile, by arranging the first air flow channel 313 in the tank body 31 and arranging the second air flow channel 3315 on the cover plate 33, the cleaning of the first air flow channel 313 and the second air flow channel 3315 by a user can be facilitated, the long-term accumulation of sewage water vapor in the first air flow channel 313 and the second air flow channel 3315 is reduced, and the practicability and the reliability of the sewage collection tank 100 are further improved.
