[0069] Combination Figures 4 to 6 As shown, the dirt collecting chamber 3 also includes a dirt inlet 33, which is connected to the inner cavity of the dirt collecting chamber 3, and the dirt inlet 33 is connected to the exhaust port 32, and the dirt inlet 33 and the dirt exhaust port 31 are separated. A dirt suction port is also provided at the bottom of the cleaning body 1, and the dirt suction port is arranged toward the outside of the cleaning body 1, so as to be suitable for facing the external surface to be cleaned, the cleaning tank of the base station, etc., so that the dirt on the external surface to be cleaned, the cleaning tank of the base station, etc. can be sucked into the dirt suction port.

Under the action of the suction force formed by the suction device 2, the sewage outlet 31 is automatically opened, and when the suction force is cancelled, the cover plate structure 5 can be automatically reset. It can be seen that there is no need to set a power device to drive the cover plate structure 5 to move, making the cover plate structure 5 simpler, and the user does not need to perform the movement operation of the cover plate structure 5, which is more worry-free to use.

[0087] Specifically, the cover plate structure 5 includes a plate body 51 and an elastic reset member. A rotating shaft is protruded from one end of the plate body 51, and the rotating shaft is rotatably connected to the cleaning body 1. The elastic reset member is configured as a torsion spring, which is disposed on the rotating shaft. The plate body 51 is disposed on the outer side of the sewage outlet 31 and can rotate toward the direction outside the sewage outlet 31. When the cleaning device 100 is in the sewage discharge working state, the suction device 2 is connected with the sewage extraction channel 2021 of the base station 200 through the first docking port 11, and the sewage extraction channel 2021 is connected with the sewage outlet 31 of the sewage collection chamber 3. When the suction device 2 forms a negative pressure in the sewage extraction channel 2021, the plate body 51 is driven to rotate toward one side of the sewage extraction channel 2021 under the action of the suction force to open the sewage outlet 31, so that the sewage in the sewage collection chamber 3 can enter the sewage extraction channel 2021 from the sewage outlet 31. When the channel between the suction device 2 and the sewage extraction channel 2021 is blocked, the plate 51 is no longer affected by the suction force, and under the elastic restoring force of the torsion spring, the plate 51 closes the sewage outlet 31 again to automatically reset. During the entire sewage discharge operation, the user does not need to perform additional operations, which is simpler and more convenient to use.

[0088] Among them, a sealing member can also be provided on the side of the plate body 51 facing the sewage outlet 31. The sealing member is arranged in an annular shape to be snapped onto the plate body 51. When the plate body 51 is in a position to close the sewage outlet 31, the sealing member is arranged around the mouth of the sewage outlet 31 to seal the sewage outlet 31 and better prevent the sewage in the sewage collecting chamber 3 from leaking out.

[0089] Since the dirt collecting chamber 3 is used to both suck in and discharge dirt, an air outlet 32, a dirt inlet 33 and a dirt discharge outlet 31 are provided on the dirt collecting chamber 3, in order to prevent dirt from being discharged from the dirt discharge outlet 31 when the cleaning device 100 is performing cleaning work, and to prevent dirt from being discharged from the dirt inlet 33 when the cleaning device 100 is in a dirt discharge working state. In this embodiment, the structure of the dirt collecting chamber 3 is specially designed. Preferably, the dirt collecting chamber 3 includes a dirt storage chamber 36, a first dirt guide channel 34 and a second dirt guide channel 35. The dirt storage chamber 36 is suitable for storing dirt. The first dirt guide channel 34 and the second dirt guide channel 35 are respectively connected to both sides of the dirt storage chamber 36. The two ends of the first dirt guide channel 34 are respectively connected to the dirt storage chamber 36 and the dirt outlet 31, and the two ends of the second dirt guide channel 35 are respectively connected to the dirt inlet 33 and the dirt storage chamber 36. The dirt in the dirt storage chamber 36 can be led out through the first dirt guide channel 34 to be discharged into the base station 200, and the external dirt can be introduced into the dirt storage chamber 36 for storage through the second dirt guide channel 35. When the cleaning device 100 is in the cleaning working state, the dirt can enter the dirt storage chamber 36 through the dirt inlet 33 along the second dirt guide channel 35 to be temporarily stored in the dirt storage chamber 36. When the cleaning device 100 is in the sewage discharge working state, the sewage in the sewage storage chamber 36 can be transported toward the sewage discharge port 31 through the first sewage guide channel 34 and enter the base station 200 through the sewage discharge port 31, so that the sewage in the sewage storage chamber 36 can be discharged from the cleaning device 100.

[0090] The sewage outlet 31 and the sewage inlet 33 are respectively located at different sides of the sewage collecting chamber 3, so that the introduction and discharge of sewage can be better separated.

When the cleaning device 100 is placed on the base station 200, the dirt in the dirt collecting chamber 3 can be discharged from the sewage outlet 31 under the action of the suction airflow, so as to enter the sewage suction section and flow into the storage box 2022. A filtering structure can be provided at the opening where the storage box 2022 is connected to the airflow section. The filtering structure allows the dirt to be retained in the storage box 2022, and the clean airflow filtered out by the filtering structure can flow to the suction device 2 through the airflow section, and then be discharged from the cleaning device 100 through the suction device 2, thereby forming a sewage airflow circulation, so that the dirt collecting chamber 3 can be self-cleaned under the action of the suction device 2 of the cleaning device 100, so that the structure of the base station 200 is simpler and easier to maintain.

[0095] Furthermore, the first end of the airflow segment is connected to the first docking port 11, the second end of the airflow segment is connected to the storage box 2022, and the opening portion 203 is arranged on the inner side of the first end of the airflow segment.

The structure of the base station 200 is simpler and the base station 200 is lighter.

[0097] In one embodiment, a cleaning tank may be provided on the base station 200, and the cleaning tank may be used to accommodate cleaning parts (such as roller brushes, rags, etc.) of the cleaning device 100 and clean the cleaning parts. The cleaning tank may be connected to the storage box 2022, and the sewage generated in the cleaning tank during the cleaning process may be sucked out when the base station 200 cleans the dirt collecting chamber 3, making the cleaning of the cleaning tank more convenient.

[0098] The utility model also provides a cleaning system 1000, combined with Figure 1 and Figure 2 As shown, the cleaning system 1000 includes the above-mentioned cleaning device 100 and the above-mentioned base station 200. The cleaning work can be performed through the cleaning device 100, and the base station 200 can provide the cleaning device 100 with clean water, electric energy, and cleaning of the dirt collection chamber 3. Specifically, when the cleaning device 100 is placed on the base station 200, a docking channel and / or an electrical connection can be formed between the cleaning device 100 and the base station 200. The cleaning device 100 can be charged through the base station 200, and a negative pressure is formed in the base station 200 through the suction device 2 on the cleaning device 100, so that the dirt in the dirt collection chamber 3 of the cleaning device 100 is sucked out to achieve self-cleaning of the cleaning device 100. The base station 200 has a simpler structure and lower cost. The entire cleaning system 1000 does not require the user to manually clean the cleaning device 100 during the cleaning process, and the cleaning effect is better. In addition, the base station 200 has a simpler structure and lighter weight, so it is more convenient to use.
