At least the sewage tank 24 is made of a transparent material, such as transparent plastic or transparent glass, to facilitate sterilization by light. The technology sterilizes the sewage collected in the sewage tank 24.

By restricting the clean water tank 22 and the sewage tank 24 to be stacked up and down, when the water levels in the clean water tank 22 and the sewage tank 24 change, the center of gravity of the water tank 20 installed on the base 10 only changes in the vertical direction, and does not change in the vertical direction. The horizontal plane is offset, thereby making the center of gravity of the cleaning device 100 more stable, and avoiding the risk of the cleaning device 100 overturning due to the offset of the center of gravity due to changes in liquid levels in each compartment of the water tank 20, and the relative wear of the running wheel on a certain side.

The fan 50 is connected to the second airflow port 202. The fan 50 is used to generate The airflow carries the dirt on the cleaning assembly 30 into the sewage tank 24 .

Among them, the first air flow port 201 and the second air flow port 202 are both connected to the inner space of the sewage bin 24. The first air flow port 201 and the second air flow port 202 can be provided in the clean water bin 22 and/or the sewage bin 24. The fan 50 pumps When the air flow generated by suction passes through the sewage tank 24, gas-liquid separation is performed in the sewage tank 24. The liquid containing dirt can be collected into the sewage tank 24, and the air flow is discharged through the exhaust port of the fan 50 after passing through the sewage tank 24.

In this embodiment, the first airflow port 201 and the second airflow port 202 are both disposed in the clean water tank 22, so that the airflow channel from the first airflow port 201 to the second airflow port 202 can be relatively located on the upper layer of the sewage tank 24, so as to Avoid the liquid accumulation area located below the sewage tank 24 (the sewage tank 24 forms a liquid accumulation area due to the collection of sewage), thereby effectively reducing the probability that the air flow directly impacts the liquid accumulation area and causes the sewage in the liquid accumulation area to splash, and can The sewage tank 24 can have a relatively larger volume and can collect more sewage containing dirt, and the depth of the sewage tank 24 can be relatively deep, so that even if the cleaning device 100 vibrates during the cruise cleaning operation, it can Because the sewage tank 24 has a large depth and an airflow port 201 and a second airflow port 202 are provided in the clean water tank 22, the risk of the sewage in the sewage tank 24 splashing out can be effectively reduced.

The air flow channel flowing through the first air flow port 201 and the second air flow port 202 passes through the sewage tank 24 and the filtrate assembly 26, and in the sewage tank 24 To perform gas-liquid separation, the filtrate assembly 26 is used to separate water vapor in the air flow to prevent the air flow from carrying water vapor into the fan 50 .

Specifically, the clean water bin 22 and the sewage bin 24 are stacked up and down. The clean water bin 22 is covered at the entrance of the sewage bin 24. The clean water bin 22 includes a separated water storage area 220 and a flow-through area 222. The water storage area 220 is used for In order to store cleaning liquid such as clean water, the flow area 222 is used to pass air flow, and the second air flow port 202 is connected to the flow area 222 .

The flow-passing area 222 is provided with a filter port 204. The filtrate component 26 is connected to the clean water tank 24 and covers the filter port 204. The airflow passes from the sewage tank 24 through the filtrate component 26, the filter port 204 and the flow-passing area 222 to the second airflow port 202. .

Specifically, the sewage tank 24 has a cavity structure, and the clean water tank 22 includes a diverter plate 221. The diverter plate 221 is disposed between the first airflow port 201 and the filtrate assembly 26 to break up the filtrate flowing through the first airflow port 201 to the filtrate assembly 26. The airflow changes from a relatively concentrated state when entering through the first airflow port 201 to a dispersed state after being dispersed by the splitter plate 221, so as to reduce the impact intensity of the airflow, that is, the impact intensity of the dispersed airflow becomes smaller, so it can Effectively reduce the probability of sewage splashing caused by airflow impacting the liquid accumulation area.

The manifold plate 221 is arranged symmetrically, and the distance between the lower edge of the manifold plate 221 and the bottom wall of the sewage tank 24 gradually decreases from the symmetrical center to the edge, so that the airflow can be dispersed along the manifold plate 221 along its various directions. The lower edge flows toward the filtrate assembly 26.

The first airflow port 201 is arranged corresponding to the symmetrical center of the splitter plate 221. The distance between the lower edge of the splitter plate 221 at the symmetrical center position and the bottom wall of the sewage tank 24 is the largest, so as to facilitate the flow to the filtrate assembly through the lower edge here. The airflow of 26 can flow into the filtrate assembly 26 more quickly, avoiding impact on the liquid accumulation area; and the airflow after detouring along the splitter plate 221 has a reduced flow rate, and is drawn by the suction of the fan 50 to bypass the splitter plate 221 and then directly towards the filtrate assembly. 26 flow, so that the probability of impacting the liquid accumulation area is smaller, the flow rate is gentler, and it is also conducive to gas-liquid separation.

The flow of air into the guide plate 223 also facilitates the separation of gas and liquid, thereby facilitating the collection of sewage in the sewage bin 24. Since the splitter plate 221 and the guide plate 223 are plate structures, they have a smaller probability of retaining sewage, which allows almost all the sewage to be collected. Collected in sewage tank 24.
