[0142] In this embodiment, the dirt collecting chamber 3 can be used to store dirt sucked in by the cleaning device 100 during the cleaning process, the suction device 2 can be used to generate suction force, and the air duct switching structure 4 can be used to connect the base station 200 and the suction device 2 when the cleaning device 100 is connected to the base station 200; so that when the suction device 2 is working, a negative pressure can be formed in the base station 200, and the dirt in the dirt collecting chamber 3 can be discharged from the sewage outlet 31 of the dirt collecting chamber 3 into the base station 200 to achieve self-cleaning of the dirt collecting chamber 3; moreover, the air duct switching structure 4 is arranged between the exhaust port 32 of the dirt collecting chamber 3 and the suction device 2, and the arrangement of the air duct switching structure 4, the dirt collecting chamber 3 and the suction device 2 is more compact, and the space occupied is smaller. The effect of the air duct switching structure 4 makes it unnecessary to set up a power device for discharging the cleaning device 100 in the base station 200, so that the structure of the base station 200 can be simpler and the cost can be lower.

[0143] As shown in Figures 4 to 6, 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 is connected to the exhaust port 32. The dirt inlet 33 and the exhaust port 31 are separated. A dirt suction port is also provided at the bottom of the cleaning body 1. The dirt suction port is arranged toward the outside of the cleaning body 1 so as to be suitable for facing external surfaces to be cleaned, cleaning tanks of base stations, etc., so that dirt on external surfaces to be cleaned, cleaning tanks of base stations, etc. can be sucked into the dirt suction port. The air duct switching structure 4 also includes a second channel. The air duct switching structure 4 has a second working state in which the second channel is connected to the suction device 2 and the exhaust port 32, so that external dirt can enter the dirt collecting chamber 3 from the dirt inlet 33. Specifically, when the cleaning equipment 100 performs normal cleaning work, the air duct switching structure 4 can be adjusted to the second working state, and the suction device 2 and the sewage collecting chamber 3 are connected through the air duct switching structure 4 and the exhaust port 32, so that a negative pressure is formed in the sewage collecting chamber 3 under the action of the suction device 2, and a negative pressure is also formed in the connecting pipe between the sewage suction port and the sewage inlet 33. Under the action of the suction force at the sewage suction port, external dirt can enter the connecting pipe between the sewage suction port and the sewage inlet 33, and enter the sewage collecting chamber 3 from the sewage inlet 33. A filter component can be provided at the exhaust port 32, and the air flow is filtered by the filter component. The filtered clean gas can be discharged from the exhaust port 32, enter the suction device 2 through the air duct switching structure 4, and finally be discharged from the cleaning equipment 100.

[0144] The cleaning device 100 has a sewage discharge working state connected to the base station 200, and a cleaning working state connected to the sewage collecting chamber 3, making the working mode of the cleaning device 100 more diverse. In addition, the suction device 2 on the cleaning device 100 can provide cleaning power for cleaning work and also provide sewage discharge power for its own sewage collecting chamber 3, thereby improving energy utilization. In addition, this setting method eliminates the need to set a power device for cleaning the sewage collecting chamber 3 on the base station 200 connected to the cleaning device 100, which can simplify the structure of the base station 200 and reduce the production cost of the base station 200, thereby saving users' usage costs.

[0145] The cleaning device 100 can be configured as a floor scrubber, a floor sweeper, or a vacuum cleaner, etc. Preferably, the cleaning device 100 is configured as a floor scrubber, and the cleaning device 100 further includes a floor brush mechanism provided at the bottom of the cleaning body 1, and the sewage suction port is provided at the bottom of the floor brush mechanism. The specific structure of the floor brush mechanism is not limited, and the floor brush mechanism can be a single roller floor brush, a double roller floor brush, or a replaceable mop floor brush, etc. The cleaning body 1 is roughly cylindrical in shape. When the cleaning device 100 is normally placed, the axial direction of the cleaning body 1 is provided in the up-down direction, and the floor brush mechanism is located below the cleaning body 1. The forward direction of the cleaning device 100 during normal cleaning operation is forward, and the backward direction is rearward. The description of the relevant directions in this disclosure shall refer to the above directions unless otherwise specified.

[0146] Preferably, the suction device 2, the air duct switching structure 4, and the dirt collection chamber 3 are arranged in this order from top to bottom. The dirt collection chamber 3 is detachably mounted on the cleaning body 1, and can be located at the front or rear side of the cleaning body 1. The dirt collection chamber 3 is positioned closer to the bottom of the cleaning body 1, which lowers the center of gravity of the entire cleaning device 100 and shortens the dirt suction channel, resulting in greater stability, higher cleaning efficiency, and less effort for the user.

[0147] The suction device 2 may include a fan 21 and a fan housing 22. The fan 21 may be configured as an axial flow fan or a centrifugal fan. The fan housing 22 has a receiving cavity, and the fan 21 is disposed in the receiving cavity. The fan housing 22 is connected and fixed to the cleaning body 1. The fan housing 22 has an air inlet connected to the air inlet end of the fan 21 and an air outlet connected to the air outlet end of the fan 21. The air inlet on the fan housing 22 is connected to the air duct switching structure 4, so that the suction device 2 can be connected to the sewage collecting chamber 3 and the base station 200 respectively, making the connection between the air duct switching structure 4 and the suction device 2 more convenient.

[0148] In one embodiment, as shown in Figures 3, 4, and 10, a first docking port 11 is provided on the outside of the cleaning body 1, which can be connected to the sewage extraction channel 2021 on the base station 200. Regarding the air duct switching structure 4, the air duct switching structure 4 includes a first opening 41 and a second opening 42. The first channel connects the first opening 41 and the second opening 42, and the first opening 41 is connected to the suction device 2. A suction duct 7 is formed within the cleaning body 1, and the suction duct 7 connects the second opening 42 and the first docking port 11, thereby connecting the first docking port 11 and the second opening 42. When the air duct switching structure 4 is in the first working state, the first opening 41 and the second opening 42 are connected, and the second opening 42 and the first docking port 11 are connected, so that the suction device 2 is connected to the base station 200. Under the action of the suction airflow of the suction device 2, the dirt in the sewage collecting chamber 3 can enter the sewage suction channel 2021 of the base station 200 from the sewage outlet 31, and the clean airflow filtered out of the dirt enters the first channel from the sewage suction channel 2021 through the first docking port 11, and then enters the suction device 2, and then is discharged from the cleaning equipment 100 through the suction device 2, forming an airflow circulation path during sewage discharge operation.

[0149] Furthermore, as shown in Figure 10, the air duct switching structure 4 also includes a third opening 43, which is in contact with and communicates with the exhaust port 32. The second channel connects the first opening 41 and the third opening 43. When the air duct switching structure 4 is in the second operating state, the suction device 2 is in contact with the first opening 41, and the first opening 41 and the third opening 43 are in contact. The third opening 43 is in contact with the exhaust port 32, thereby connecting the suction device 2 to the dirt collection chamber 3. The operation of the suction device 2 creates a negative pressure in the dirt collection chamber 3, allowing external dirt to enter the cleaning body 1 through the dirt suction port and then enter the dirt collection chamber 3 through the dirt inlet 33.

[0150] As for the air duct switching structure 4, preferably, in combination with Figures 9 to 11, the air duct switching structure 4 includes a reversing shell 44, a reversing body 45 and a switching drive component, wherein the above-mentioned first opening 41, second opening 42 and third opening 43 are all provided on the reversing shell 44; the reversing body 45 is rotatably provided in the reversing shell 44 and is driven and connected to the switching drive component; the switching drive component drives the reversing body 45 to rotate, so that the reversing body 45 can conduct the first channel and block the second channel to be in the first working state, and the reversing body 45 can conduct the second channel and block the first channel to be in the second working state, and the switching between the first working state and the second working state is realized by the rotation of the reversing body 45.

[0151] In one embodiment, as shown in Figure 10 , the reversing housing 44 is integrally formed with the fan housing 22. The suction duct 7 is connected to one side of the fan housing 22 and is axially opposed to the switching drive component along the reversing body 45, providing a more secure connection. The suction duct 7 extends vertically along the cleaning device 100, with the first docking port 11 exposed on the outer surface of the cleaning body 1 to facilitate docking with the base station 200.

[0152] Furthermore, the reversing body 45 is provided with a first through-hole, a second through-hole, a third through-hole, a first shielding portion, and a second shielding portion. When the air duct switching structure 4 is in the first operating state, the first through-hole is in relative communication with the first opening 41, the second through-hole is in relative communication with the second opening 42, and the first shielding portion is arranged to block the third opening 43, thereby connecting the suction device 2 to the base station 200 and the cleaning device 100 to the sewage discharge operating state. When the air duct switching structure 4 is in the second operating state, the first through-hole is in relative communication with the third opening 43, the third through-hole is in relative communication with the second opening 42, and the second shielding portion is arranged to block the second opening 42, thereby connecting the suction device 2 to the exhaust port 32 of the sewage collecting chamber 3 and the cleaning device 100 to the cleaning operating state.

[0153] In another embodiment, the reversing housing 44' is independently provided from the fan housing 22. The reversing body 45' includes a reversing baffle. A first opening 41', a second opening 42', and a third opening 43' are spaced apart along the circumference of the reversing housing 44'. The first opening 41' communicates with the suction device 2, the second opening 42' communicates with the base station 200, and the third opening 43' communicates with the sewage collecting chamber 3. The reversing baffle is rotatably disposed within the reversing housing 44'. By blocking the third opening 43', the first opening 41' and the second opening 42' are connected, thereby connecting the suction device 2 and the base station 200. By blocking the second opening 42', the first opening 41' and the third opening 43' are connected, thereby connecting the suction device 2 and the sewage collecting chamber 3, thereby switching the air duct switching structure 4 between the two working states.

[0154] Preferably, in combination with Figures 3 and 4, the above-mentioned sewage outlet 31 is also arranged on the outer surface of the cleaning body 1, and the sewage outlet 31 and the first docking port 11 are both arranged on the front side of the cleaning body 1. When the cleaning equipment 100 is placed on the base station 200, the docking operation is more convenient.

[0155] Moreover, the setting position of the first docking interface 11 is higher than the setting position of the sewage outlet 31, that is, the first docking interface 11 is located above the sewage outlet 31, so that the first docking interface 11 is closer to the suction device 2, and the sewage outlet 31 is closer to the sewage collecting chamber 3, so that the suction force formed in the base station 200 is greater and the sewage discharge effect is better.

[0156] Preferably, the sewage outlet 31 is arranged downward, and the cleaning device 100 further includes a valve structure 6 disposed at the sewage outlet 31, which can open and close the first docking port 11. When the cleaning device 100 is placed on the base station 200, the valve structure 6 can be opened by the opening portion 203 of the base station 200, so that the first docking port 11 is in an open state, thereby connecting the base station 200 and the suction duct 7.

[0157] Specifically, the valve structure 6 includes a valve body and a valve core. The valve core is retractably disposed within the valve body. When the cleaning device 100 is performing a cleaning operation, the valve core is in an extended state to block the valve body from communicating with the outside. When the cleaning device 100 is docked with the base station 200, the valve core is compressed by the push-pull action of the opening portion 203 of the base station 200 to open the opening connecting the valve body to the outside, thereby connecting the sewage extraction channel 2021 within the base station 200 to the suction duct 7 of the cleaning device 100, thereby connecting the base station 200 to the suction device 2. Furthermore, the first docking port 11 is disposed downward. When the cleaning device 100 is placed on the base station 200, the weight of the cleaning device 100 causes the opening portion 203 of the base station 200 to push against the valve core and move. The user does not need to apply an opening force, making operation more labor-saving.

[0158] As shown in Figures 3, 4, and 8, a cover structure 5 can be provided at the drain outlet 31. The cover structure 5 is movably provided on the cleaning body 1 to open and close the drain outlet 31. When the cleaning device 100 is in the cleaning operation state, the cover structure 5 is provided to close the drain outlet 31 to prevent the dirt in the dirt collecting chamber 3 from leaking out of the drain outlet 31. When the cleaning device 100 is in the draining operation state, the cover structure 5 can open the drain outlet 31, so that the dirt in the dirt collecting chamber 3 can be discharged from the drain outlet 31 and enter the base station 200.

[0159] In one embodiment, the cover structure 5 can be arranged on the cleaning body 1 in a linear reciprocating manner to open and close the sewage outlet 31. For example, the cover structure 5 can move along the up and down directions of the cleaning body 1. When the cover structure 5 moves upward, the sewage outlet 31 is opened, and when it moves downward, the sewage outlet 31 is reclosed. Alternatively, the cover structure 5 has a movable stroke along the front and back directions of the cleaning body 1. The cover structure 5 moves forward to open the sewage outlet 31, and the cover structure 5 resets backward to close the sewage outlet. In another embodiment, the cover structure 5 is configured as a telescopic sealing structure, and the opening and closing of the sewage outlet 31 is achieved by the telescopic movement of the cover structure 5. The configuration of the cover structure 5 includes but is not limited to the above.

[0160] Preferably, the cover plate structure 5 is rotatably mounted on the cleaning body 1; when the cleaning device 100 is connected to the base station 200, so that a negative pressure is formed in the base station 200, the cover plate structure 5 rotates under the action of the suction force to open the sewage outlet 31; when the suction force applied to the cover plate structure 5 is withdrawn, the cover plate structure 5 can be reset to close the sewage outlet 31. 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 withdrawn, 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 operation of moving the cover plate structure 5, which is more worry-free to use.

[0161] Specifically, the cover 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 covers the outer side of the sewage outlet 31 and can rotate toward the outside of the sewage outlet 31. When the cleaning device 100 is in the sewage discharge working state, the suction device 2 is connected to the sewage extraction channel 2021 of the base station 200 through the first docking port 11, and the sewage extraction channel 2021 is connected to the sewage outlet 31 of the sewage collecting chamber 3. When the suction device 2 creates 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 collecting chamber 3 can enter the sewage extraction channel 2021 from the sewage outlet 31. When the passage between the suction device 2 and the sewage extraction passage 2021 is blocked, the plate 51 is no longer affected by the suction force. Under the elastic restoring force of the torsion spring, the plate 51 closes the sewage outlet 31 again and automatically resets. During the entire sewage discharge operation, the user does not need to perform additional operations, making it simpler and more convenient to use.

[0162] 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 clamped on the plate body 51. When the plate body 51 is in the position of closing 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.

[0163] 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 outlet 31 are provided on the dirt collecting chamber 3. In order to prevent dirt from being discharged from the dirt outlet 31 when the cleaning device 100 is performing a cleaning operation, and to prevent dirt from being discharged from the dirt inlet 33 when the cleaning device 100 is in a dirt discharging operation state, the structure of the dirt collecting chamber 3 is specially designed in this embodiment. Preferably, the sewage collection chamber 3 includes a sewage storage chamber 36, a first sewage channel 34, and a second sewage channel 35. The sewage storage chamber 36 is suitable for storing sewage. The first sewage channel 34 and the second sewage channel 35 are respectively connected to the two sides of the sewage storage chamber 36. The two ends of the first sewage channel 34 respectively connect the sewage storage chamber 36 and the sewage outlet 31, and the two ends of the second sewage channel 35 respectively connect the sewage inlet 33 and the sewage storage chamber 36. The sewage in the sewage storage chamber 36 can be discharged into the base station 200 through the first sewage channel 34, and external sewage can be introduced into the sewage storage chamber 36 for storage through the second sewage channel 35. When the cleaning device 100 is in the cleaning working state, sewage can enter the sewage storage chamber 36 through the sewage inlet 33 and the second sewage channel 35 to be temporarily stored in the sewage 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 outlet 31 through the first sewage guide channel 34 and enter the base station 200 through the sewage outlet 31, so that the sewage in the sewage storage chamber 36 can be discharged from the cleaning device 100.

[0164] The sewage outlet 31 and the sewage inlet 33 are respectively located on different sides of the sewage collecting chamber 3 , so that the introduction and discharge of sewage can be better separated.

[0165] Preferably, the sewage inlet 33 is located at the bottom of the sewage collecting chamber 3, and is closer to the sewage suction port of the cleaning device 100, so as to achieve a better sewage suction effect. The sewage outlet 31 is located on the peripheral side of the sewage collecting chamber 3 and is close to the top of the sewage collecting chamber 3, so that the sewage outlet 31 can be arranged as far away from the sewage inlet 33 as possible, thereby preventing the sewage sucked into the sewage storage chamber 36 from the sewage inlet 33 from accidentally entering the sewage outlet 31.

[0166] Further preferably, as shown in Figures 6 to 8 , the first sewage channel 34 and the second sewage channel 35 are arranged in parallel, and the connection between the first sewage channel 34 and the sewage storage chamber 36 is located near the bottom of the sewage collection chamber 3, while the connection between the second sewage channel 35 and the sewage storage chamber 36 is located near the top of the sewage collection chamber 3. The two sewage channels can isolate the sewage outlet 31 and the sewage inlet 33 to prevent sewage from blocking the sewage outlet 31 and causing pipe blockage. Under the action of suction force, sewage moves upward from the sewage inlet 33 along the second sewage channel 35 and enters the sewage storage chamber 36 from the top of the second sewage channel 35. The connection between the first sewage channel 34 and the sewage storage chamber 36 is located near the bottom of the sewage storage chamber 36, so that sewage at the bottom of the sewage storage chamber 36 can also better enter the first sewage channel 34, and sewage is discharged more thoroughly.

[0167] The present disclosure also provides a base station 200, as shown in Figures 1 and 2, the base station 200 includes a base station body 201 and a sewage extraction structure 202 arranged on the base station body 201, wherein the base station body 201 can provide a placement area for the cleaning equipment 100, and the sewage extraction structure 202 includes a sewage extraction channel 2021. When the base station 200 and the cleaning equipment 100 are docked, the sewage extraction channel 2021 is suitable for being connected to the first channel on the cleaning equipment 100, so that the suction force generated by the suction device 2 on the cleaning equipment 100 can enter the sewage extraction channel 2021 to suck out the dirt in the sewage collecting chamber 3 of the cleaning equipment 100, so as to realize self-cleaning of the sewage collecting chamber 3 of the cleaning equipment 100.

[0168] In one embodiment, the sewage extraction structure 202 may further include a storage box 2022, which is disposed on the sewage extraction channel 2021 and communicates with the sewage extraction channel 2021. Specifically, the sewage extraction channel 2021 includes an air flow section and a sewage extraction section, which are respectively connected to two sides of the storage box 2022. The air flow section can communicate with the first docking port 11 of the cleaning device 100 and the storage box 2022, and the sewage extraction section can communicate with the storage box 2022 and the sewage outlet 31 of the cleaning device 100. 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, 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.

[0169] 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 provided on the inner side of the first end of the airflow segment. The first end of the airflow segment is provided to protrude from the base station 200, and the open mouth of the airflow segment is provided to face upward. When the cleaning device 100 is connected to the base station 200, the first end of the airflow segment can be inserted into the first docking port 11, and the opening portion 203 abuts against the valve structure 6, wherein the opening portion 203 is provided as an abutting protrusion, and the abutting protrusion abuts against the valve core of the valve structure 6, thereby opening the first docking port 11, so that the suction duct 7 is connected to the airflow segment.

[0170] The base station 200 may be provided with a clean water tank. When the cleaning device 100 is docked with the base station 200, clean water can be supplied to the clean water tank of the cleaning device 100 through the clean water tank. Alternatively, the base station 200 may not need to be provided with a clean water tank. Instead, the base station 200 may be provided with a three-way valve structure. When the cleaning device 100 needs to be replenished with water, the three-way valve structure connects the tap water pipe and the clean water tank on the cleaning device 100, thereby replenishing the clean water tank of the cleaning device 100. This makes the base station 200 structure simpler and lighter.

[0171] In one embodiment, a cleaning tank may be provided on the base station 200. The cleaning tank may be used to accommodate and clean the cleaning components (such as a roller brush, a rag, etc.) of the cleaning device 100. The cleaning tank may be connected to the storage box 2022. The wastewater generated during the cleaning process in the cleaning tank may be sucked out of the cleaning tank when the base station 200 cleans the sewage collecting chamber 3, making cleaning of the cleaning tank more convenient.

[0172] The present disclosure also provides a cleaning system 1000, as shown in Figures 1 and 2, the cleaning system 1000 includes the above-mentioned cleaning device 100 and the above-mentioned base station 200. Cleaning work can be performed through the cleaning device 100, and clean water, electricity, and cleaning of the dirt collection chamber 3 can be provided to the cleaning device 100 through the base station 200. 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, thereby sucking out the dirt in the dirt collection chamber 3 of the cleaning device 100 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.

[0173] The present disclosure provides another cleaning system, as shown in FIG13 . The cleaning system 1000 includes a cleaning device 100 and a base station 200 . As shown in FIG14 to FIG17 , the cleaning device 100 includes a body 110 and a floor brush mechanism 8 pivotally connected to the bottom of the body 110 . A handle 190 for the user to hold is provided at the top of the body 110 . The handle 190 is provided with function keys (not shown). The function keys include an on / off key, a cleaning mode key, a self-cleaning key, etc. These keys can be independent keys, or any number of them can be the same key. A cleaning roller brush 81 and a suction port 82 (not shown) are provided at the bottom of the floor brush mechanism 8 . The cleaning roller brush 81 contacts the surface to be cleaned and is used to wet-wipe the surface to be cleaned and collect dust on the surface to be cleaned to the suction port 82 . When performing a cleaning task, the user holds the handle 190 and pushes the body 110 and floor brush mechanism 8 forward or backward on the surface to be cleaned, thereby completing the cleaning operation of the surface to be cleaned.

[0174] The body 110 also includes a dirt collection chamber 3, a cleaning liquid tank 9, and a suction device 2, located between the handle 190 and the floor brush mechanism 8. The dirt collection chamber 3 is detachably mounted on the body 110, allowing the user to manually empty the dirt within. The cleaning liquid tank 9 is also detachably mounted on the body 110, allowing the user to manually add cleaning liquid.

[0175] The suction device 2 is located near the handle 190 and is used to generate a suction airflow. A fluid passage is formed between the suction port 82 of the floor brush mechanism 8, the dirt collecting chamber 3, and the suction device 2. When the suction device 2 is working, the suction airflow generated by the suction device 2 can cause the suction port 82 of the floor brush mechanism 8 to be in a negative pressure state, thereby being able to suck the dirt at the suction port 82 into the dirt collecting chamber 3, and the airflow flowing out of the dirt collecting chamber 3 is sucked into the suction device 2 and finally discharged through the air outlet of the suction device 2 (not shown).

[0176] A liquid passage is formed between the cleaning liquid tank 9 and the floor brush mechanism 8, and the cleaning liquid tank 9 and the floor brush mechanism 8 are selectively connected. Thus, the cleaning liquid tank 9 can supply liquid to the cleaning roller brush 81 through the liquid passage to wet the cleaning roller brush 81. The liquid in the cleaning liquid tank 9 can be clean water, a mixture of detergent and clean water, or other functional liquid.

[0177] Furthermore, a liquid passage may be formed between the cleaning liquid tank 9 and the dirt collecting chamber 3, and the cleaning liquid tank 9 and the dirt collecting chamber 3 are selectively connected. Thus, the cleaning liquid tank 9 can supply liquid to the dirt collecting chamber 3 through the liquid passage for cleaning the dirt collecting chamber 3. Specifically, a cleaning nozzle (not shown) or a liquid uniformity structure (not shown) is provided at the top of the dirt collecting chamber 3. The cleaning nozzle or the liquid uniformity structure can evenly spray the liquid onto the inner wall of the dirt collecting chamber 3, flushing downward from the top along the inner wall of the dirt collecting chamber 3, thereby cleaning the dirt collecting chamber 3.

[0178] In this embodiment, the dirt collection chamber 3 is selectively connected to the suction device 2. A first docking port 11 is provided on the outer wall of the housing 110, which selectively connects to the suction device 2. "Selective connection" means that the dirt collection chamber 3 and the suction device 2 are connected, but not always. Similarly, the first docking port 11 is connected, but not always, to the suction device 2.

[0179] The body 110 has an internal air duct switching structure 4, which is connected to the suction device 2, the sewage collecting chamber 3, and the first docking port 11, respectively, and is located between the suction device 2 and the sewage collecting chamber 3. The air duct switching structure 4 is used to achieve selective connection between the suction device 2 and the sewage collecting chamber 3, and selective communication between the suction device 2 and the first docking port 11.

[0180] Specifically, when the suction device 2 is connected to the dirt collection chamber 3, the suction device 2 and the first docking port 11 are disconnected. At this time, the cleaning device 100 performs cleaning, self-cleaning and other tasks, and the dirt on the surface to be cleaned and the dirt generated by self-cleaning are stored in the dirt collection chamber 3 under the action of the suction airflow of the suction device 2. When the suction device 2 is connected to the first docking port 11, the suction device 2 and the dirt collection chamber 3 are disconnected. At this time, the cleaning device 100 is in a sewage discharge state, and the suction device 2 provides a suction airflow to the first docking port 11, so that the first docking port 11 is in a negative pressure state.

[0181] As shown in Figures 19 to 21, the air duct switching structure 4 includes a reversing housing 44 and a reversing body 45 rotatably disposed within the reversing housing 44. The reversing housing 44 has a first opening 41, a second opening 42, and a third opening 43, each of which communicates with the inner cavity of the reversing housing 44. The first opening 41 communicates with the suction device 2, the second opening 42 communicates with the sewage collecting chamber 3, and the third opening 43 communicates with the first docking port 11.

[0182] The reversing body 45 is housed within the inner cavity of the reversing housing 44 and is used to adjust the opening and closing states of the second opening 42 and the third opening 43. The first opening 41 is normally open. The first, second, and third openings 42, 43 are connected in the following states: In the first state, the reversing body 45 closes the third opening 43, connecting the first opening 41 with the second opening 42. In this state, the air duct switching structure 4 connects the suction device 2 with the sewage collection chamber 3. In the second state, the reversing body 45 closes the second opening 42, connecting the first opening 41 with the third opening 43. In this state, the air duct switching structure 4 connects the suction device 2 with the first docking port 11.

[0183] In one embodiment, as shown in Figures 15 and 16, the third opening 43 is connected to an intermediate air duct 130, which is accommodated in the body 110. The intermediate air duct 130 has an air inlet end and an air outlet end, wherein the air inlet end of the intermediate air duct 130 is the first docking port 11, and the air outlet end of the intermediate air duct 130 is connected to the third opening 43. A avoidance opening 101 for avoiding the first docking port 11 is provided on the outer wall of the cleaning device 100, and the first docking port 11 is located at the avoidance opening 101. In another embodiment, the third opening 43 is not provided with an intermediate air duct 130, and the third opening 43 is the first docking port 11, which is directly accommodated in the avoidance opening on the outer wall of the body 110.

[0184] Preferably, the first docking port 11 is distributed close to the suction device 2 , thereby shortening the airflow path between the first docking port 11 and the suction device 2 to reduce wind resistance and increase the negative pressure value at the first docking port 11 .

[0185] The outer wall of the body 110 is also provided with a liquid inlet 12 that selectively communicates with the cleaning liquid tank 9, and a sewage outlet 31 that selectively communicates with the sewage collection chamber 3. It is worth noting that the liquid inlet 12 is selectively connected via a pump (not shown); the sewage outlet 31 is selectively connected via a cover 182 located thereon. When the cleaning device 100 is docked with the base station 200, the cover 182 is activated by the base station 200 to switch from a closed state to an open state.

[0186] In this embodiment, the first docking port 11 and the liquid injection port 12 are located on the same side of the outer wall of the body 110. Furthermore, the sewage collection chamber 3, the first docking port 11, and the liquid injection port 12 are located on the same side of the body 110, and the first docking port 11, the liquid injection port 12, and the sewage discharge port 31 are located on the same side of the outer wall of the body 110. Therefore, when designing the docking structure between the cleaning device 100 and the base station 200, only the alignment relationship between the wall surface on one side of the outer wall of the body 110 and the base station 200 needs to be considered. This can effectively simplify the docking structure between the cleaning device 100 and the base station 200 and facilitate docking.

[0187] In order to improve the aesthetics of the cleaning device 100, as shown in Figures 15 and 18, the avoidance port 101 of the body 110 has a receiving cavity 160 connected thereto, and the liquid filling port 12 and the first docking port 11 are accommodated in the receiving cavity 160. Therefore, the first docking port 11 and the liquid filling port 12 cannot be directly seen from the outside, which is beautiful and elegant.

[0188] In this embodiment, the liquid inlet 12 and the first docking port 11 are cylindrical and extend in the vertical direction, with the avoidance port 101 facing downward. The "upper and lower directions" mentioned above refer to the upper and lower directions of the cleaning device 100 when in use, with the handle 190 located at the top and the floor brush mechanism 8 located at the bottom. The "upper and lower directions" mentioned above can also be understood as the direction from the handle 190 to the floor brush mechanism 8, or the direction of gravity.

[0189] In order to make the docking structure between the cleaning equipment 100 and the base station 200 simpler and more compact, preferably, the liquid injection port 12 is distributed close to the first docking port 11. As shown in Figures 15 and 16, the first distribution form between the liquid injection port 12 and the first docking port 11: the liquid injection port 12 is located inside the first docking port 11. As shown in Figures 17 and 18, the second distribution form between the liquid injection port 12 and the first docking port 11: the liquid injection port 12 is adjacent to the first docking port 11 and is distributed side by side. Of course, the distribution form between the liquid injection port 12 and the first docking port 11 is not limited to the above two forms, and can also be other forms, for example, the liquid injection port 12 and the first docking port 11 are in a diagonal distribution form, etc., which will not be described one by one here.

[0190] In this embodiment, the cross-section of the first docking port 11 is runway-shaped, comprising a pair of parallel straight edges, and a pair of arc segments located at opposite ends of the pair of straight edges and used to connect the ends of the pair of straight edges on the same side, wherein the pair of straight edges and the pair of arc segments enclose a closed shape. The aforementioned "cross-section" refers to a cross-section perpendicular to the vertical direction. The cross-section of the first docking port 11 described below also refers to a cross-section perpendicular to the vertical direction. The runway-shaped cross-section facilitates manufacturing and docking.

[0191] The cross-sectional dimension of the first interface 11 is larger than that of the liquid injection port 12. The purpose of setting the cross-sectional dimension of the first interface 11 larger than that of the liquid injection port 12 is to improve the suction efficiency of the first interface 11.

[0192] The sidewalls of the liquid injection port 12 and the first docking port 11 are provided with a seal 150. This seal 150 improves the sealing performance of the connection between the cleaning device 100 and the base station 200. The seal 150 is annular and made of a flexible material. When the liquid injection port 12 is located within the first docking port 11, the seal 150 is provided on at least one of the outer sidewall of the liquid injection port 12 and the inner sidewall of the first docking port 11. When the liquid injection port 12 and the first docking port 11 are adjacent and arranged side by side, the seal 150 is provided on the outer sidewall of the liquid injection port 12 and the outer sidewall of the first docking port 11.

[0193] In this embodiment, the cleaning device 100 can be docked onto the base station 200 along an installation direction. The "installation direction" refers to a top-to-bottom direction, i.e., the direction of gravity. Once the cleaning device 100 is docked onto the base station 200, the suction device 2 of the cleaning device 100 can provide negative suction pressure to the base station 200 through the first docking port 11. This eliminates the need for a separate negative pressure drive source on the base station 200, effectively simplifying the structure of the base station 200.

[0194] Specifically, the base station 200 is provided with a second docking port 2100 for docking with the first docking port 11, a liquid infusion port 204 for docking with the liquid infusion port 12, and a sewage extraction channel 2021 for docking with the sewage outlet 31. The second docking port 2100 and the liquid infusion port 204 extend along the installation direction.

[0195] The positional relationship between the second docking port 2100 and the fluid infusion port 204 is determined by the positional relationship between the first docking port 11 and the fluid injection port 12. When the fluid injection port 12 is located within the first docking port 11, as shown in FIG23 , the fluid infusion port 204 is located within the second docking port 2100; when the fluid infusion port 12 is adjacent to and side by side with the first docking port 11, as shown in FIG22 , the fluid infusion port 204 is adjacent to and side by side with the second docking port 2100. Regardless of whether the fluid infusion port 12 is located within the first docking port 11 or adjacent to and side by side with the first docking port 11, the close proximity of the second docking port 2100 and the fluid infusion port 204 effectively reduces the space occupied by the docking structure and makes the overall structure compact.

[0196] Regarding the structure of the base station 200, in one embodiment, as shown in FIG22 , the base station 200 is provided with a storage box 2022, but is not provided with a liquid storage container 205, wherein the storage box 2022 is used to accommodate the dirt in the dirt collecting chamber 3, and the liquid storage container 205 is used to replenish the cleaning liquid tank 9. The sewage extraction channel 2021 and the second docking port 2100 are respectively connected to the storage box 2022. When the cleaning device 100 is docked with the base station 200, the first docking port 11 is connected to the storage box 2022 through the second docking port 2100. At this time, the suction negative pressure generated by the suction device 2 acts on the storage box 2022, causing the storage box 2022 to be in a negative pressure state. Under the action of the above-mentioned negative pressure, the dirt in the dirt collecting chamber 3 can enter the storage box 2022 through the sewage outlet 31 and the sewage extraction channel 2021.

[0197] In another embodiment, the base station 200 does not include either the storage tank 2022 or the liquid storage container 205. In this case, the sewage extraction channel 2021 is connected to the sewage discharge pipe, and the negative pressure of the second docking port 2100 acts on the sewage discharge pipe, causing the sewage in the sewage collection chamber 3 to enter the sewage discharge pipe through the sewage discharge port 31 and be discharged. The liquid replenishment port 204 is connected to the municipal water source. When the cleaning liquid tank 9 needs to be replenished, municipal water is added to the cleaning liquid tank 9 through the liquid replenishment port 204 and the liquid filling port 12.

[0198] In another embodiment, as shown in FIG23 , the base station 200 is provided with both a storage box 2022 and a liquid storage container 205, and the liquid inlet 204 is selectively connected to the liquid storage container 205. When the cleaning device 100 is docked with the base station 200, the liquid inlet 204 is connected to the liquid storage container 205 via the liquid injection port 12; when the cleaning device 100 is separated from the base station 200, the liquid inlet 204 and the liquid storage container 205 are disconnected.

[0199] The present disclosure discloses another cleaning system, as shown in Figures 24 and 25, the cleaning system includes a cleaning device 100 and a base station 200, the cleaning device 100 can be docked on the base station 200, and the base station 200 is used to adapt to the cleaning device 100. In one application scenario, the cleaning device 100 is a floor scrubber, and the base station 200 is a base station suitable for a floor scrubber. In another application scenario, the cleaning device 100 is a vacuum cleaner, and the base station 200 is a base station suitable for a vacuum cleaner. Of course, the cleaning device 100 includes but is not limited to floor scrubbers and vacuum cleaners, and can also be other devices with cleaning functions, which are not described one by one here. Similarly, the base station 200 includes but is not limited to base stations suitable for floor scrubbers and vacuum cleaners, and can also be other base stations adapted to cleaning equipment.

[0200] The following description will be made by taking the cleaning device 100 as a floor scrubber and the base station 200 as a base station suitable for a floor scrubber as an example. However, based on the above description, it can be seen that the protection scope of the present disclosure is not limited thereby.

[0201] As shown in Figures 26 to 28, the floor scrubber is provided with a suction device 2, a dirt collecting chamber 3, and a cleaning liquid tank 9. The suction device 2 is used to generate a suction force. Under the action of the suction force, external dirt can be sucked into the dirt collecting chamber 3 through the suction port 82 of the floor brush mechanism 8 at the bottom of the floor scrubber, and the airflow through the dirt collecting chamber 3 is discharged from the floor scrubber by the suction device 2, thereby achieving tasks such as cleaning the surface to be cleaned and self-cleaning. Specifically, the suction device 2 is a fan. When the fan is working, it can generate a suction airflow (suction force), and the suction airflow causes the suction port 82 and the dirt collecting chamber 3 to be in a negative pressure state.

[0202] The cleaning liquid tank 9 is used to store cleaning liquid. A fluid channel is formed between the cleaning liquid tank 9 and the roller brush 81 of the floor brush mechanism 8. The liquid in the cleaning liquid tank 9 can moisten the roller brush 81 through the fluid channel to achieve wet cleaning of the surface to be cleaned, self-cleaning of the roller brush and other tasks.

[0203] The floor scrubber's housing is equipped with a first docking port 11 that connects to the suction device 2, a drain port 31 that communicates with the dirt collection chamber 3, and a liquid replenishment port 204 that selectively connects to the cleaning liquid tank 9. The liquid replenishment port 204 is located near the first docking port 11, which is in turn located near the suction device 2. The drain port 31 is used to provide an opening for waste in the dirt collection chamber 3 to be discharged to the base station 200 after the floor scrubber is docked with the base station 200.

[0204] A cover 182 is pivotally connected to the drain outlet 31. The cover 182 has a first state, covering the drain outlet 31, and a second state, leaving the drain outlet 31 open. When the scrubber is docked with the base station 200, the base station 200 activates the cover 182 to switch from the first state to the second state. At this point, the negative pressure suction force of the base station 200 draws waste from the sump chamber 3 into the base station 200.

[0205] In this embodiment, the suction device 2 is connected to either the dirt collecting chamber 3 or the first docking port 11. The above-mentioned "connection with either one" is achieved by a valve structure 130 built into the floor scrubber. When the floor scrubber performs the task of sucking dirt during cleaning of the surface to be cleaned, self-cleaning, etc., the suction device 2 is connected to the dirt collecting chamber 3. At this time, the suction device 2 is not connected to the first docking port 11. Under the action of the suction force generated by the suction device 2, external dirt is sucked into the dirt collecting chamber 3. When the floor scrubber is docked to the base station 200, the suction device 2 is connected to the first docking port 11. There is no connection between the suction device 2 and the dirt collecting chamber 3. At this time, the suction force generated by the suction device 2 acts on the first docking port 11, and the first docking port 11 acts on the base station 200. As a result, the base station 200 does not need to be provided with a negative pressure drive source, thereby simplifying the overall structure of the cleaning system, facilitating installation and maintenance, and also reducing the production cost of the cleaning system.

[0206] As shown in Figures 29 to 32, the base station 200 includes a base station body, which is provided with a base station air duct opening 210 and a sewage extraction channel 2021. The base station air duct opening 210 is used to connect with the first docking port 11, and the sewage extraction channel 2021 is used to connect with the sewage outlet 31 of the sewage collecting chamber 3. When the floor scrubber is docked with the base station 200, the first docking port 11 and the base station air duct opening 210 are connected, and the sewage outlet 31 of the sewage collecting chamber 3 is connected with the sewage extraction channel 2021. Under the action of negative pressure, the dirt in the sewage collecting chamber 3 can be sucked into the base station 200.

[0207] Specifically, as shown in Figures 33 and 34 , a sealing structure 400 is provided on at least one of the base station air duct opening 210 and the first docking port 11. The sealing structure 400 is used to form a sealed connection between the base station air duct opening 210 and the first docking port 11 when the scrubber is docked with the base station 200. In other words, when the scrubber is docked with the base station 200, the connection between the first docking port 11 and the base station air duct opening 210, and the connection between the sewage outlet 31 of the sewage collecting chamber 3 and the sewage extraction channel 2021, are in a sealed state.

[0208] Among them, the sealing structure 400 is a sealing ring fixedly installed on the inner wall or outer wall of the base station air duct opening 210 and the first docking interface 11; or, the sealing structure 400 includes ribs (not shown) and sealing grooves (not shown), one of the ribs and the sealing grooves is arranged at the base station air duct opening 210, and the other is arranged at the first docking interface 11. When the floor scrubber is docked with the base station 200, the ribs are accommodated in the sealing groove to form a labyrinth sealing structure.

[0209] In response to the docking of the scrubber and the base station, the base station air duct opening 210 communicates with the suction device 2 via the first docking port 11, creating a negative pressure in the sewage extraction channel 2021. In other words, after the scrubber is docked with the base station 200, the suction device 2 communicates with the base station air duct opening 210 via the first docking port 11. With the negative pressure in the sewage extraction channel 2021, waste within the sewage collection chamber 3 is drawn through the sewage outlet 31 and the sewage extraction channel 2021 into the base station 200, thereby automatically cleaning the waste within the sewage collection chamber 3.

[0210] The air duct opening 210 of the base station is closer to the suction device 2 than the sewage extraction channel 2021. Herein, closer can be judged by a preset direction, a straight-line distance, etc. The preset direction can be the docking direction between the floor scrubber and the base station body. For example, if the floor scrubber is docked to the base station in a downward plug-in manner, the preset direction is the vertical direction up and down. If the floor scrubber is docked to the base station horizontally, the preset direction is the horizontal direction. The preset direction can also be a specified direction, such as a specified direction parallel to the bottom surface of the base station. The straight-line distance can be the distance between the center of the air duct opening 210 of the base station and the center of the suction device 2, and the distance between the center of the sewage extraction channel 2021 and the center of the suction device 2.

[0211] Alternatively, in the docking direction between the floor scrubber and the base station body, the base station air duct opening 210 is arranged between the sewage extraction channel 2021 and the suction device 2. The above arrangement of the base station air duct opening 210 can shorten the airflow path between the base station air duct opening 210 and the suction device 2, thereby reducing wind resistance, maximizing the suction force acting on the base station 200, and improving sewage extraction efficiency. The above "docking direction" can refer to: the direction from top to bottom. Specifically, the base station air duct opening 210 is arranged upward, and the first docking port 11 is arranged downward.

[0212] As shown in Figures 30 and 32, the base station 200 has a raised portion 230 on its housing. The base station air duct opening 210 is formed at the top of the raised portion 230 and faces upward. In one embodiment, as shown in Figure 32, a sewage extraction channel 2021 is also provided on the raised portion 230, extending toward the sewage collection chamber 3. The raised portion 230 can be understood as the structure on the base station 200 for docking with the floor scrubber. The raised portion 230 extends in the docking direction and can be block-shaped or columnar, with no particular limitation on shape.

[0213] The base station body is equipped with a storage box 2022, which is connected to the base station air duct opening 210 and the sewage extraction channel 2021. When the base station air duct opening 210 is connected to the suction device 2, the storage box 2022 connected to the base station air duct opening 210 also experiences a negative pressure state, which in turn causes the sewage extraction channel 2021 connected to the storage box 2022 to also experience a negative pressure state. As a result, the negative pressure allows waste within the sewage collection chamber 3 to enter the storage box 2022, completing the automatic cleaning of the waste.

[0214] To ensure effective drainage and the sewage storage capacity of the storage box 2022, the connection points between the base station air duct opening 210 and the storage box 2022, and the connection points between the sewage extraction channel 2021 and the storage box 2022, are respectively located near the top of the storage box 2022. Specifically, the base station air duct opening 210 is connected to the storage box 2022 through a first channel 211, and the sewage extraction channel 2021 is connected to the storage box 2022 through a second channel 221. The first channel 211 is shorter than the second channel 221.

[0215] Furthermore, a filtering structure (not shown) is provided on the base station body, and the base station air duct opening 210 is connected to the storage box 2022 through the filtering structure. The filtering structure has the function of filtering the air flow, preventing the dirt in the storage box 2022 from entering the first docking port 11 through the base station air duct opening 210, thereby isolating the dirt in the storage box 2022.

[0216] The filter structure is disposed on the top of the storage box 2022 and is in communication with the storage box 2022. This prevents the filter structure from occupying the volume of the storage box 2022 and facilitates replacement of the filter structure. The filter structure may be HEPA, activated carbon, or the like.

[0217] The base station body is also provided with a sewage pipe (not shown) connected to the storage box 2022, and the sewage pipe is connected to the underground pipeline (not shown) for sewage discharge. When the dirt in the sewage collecting chamber 3 enters the storage box 2022, it is discharged from the base station 200 through the sewage pipe. In one embodiment, in order to simplify the structure of the base station 200, the base station body is not provided with a storage box 2022, and the sewage extraction channel 2021 on the base station body is connected to the sewage pipe. The base station air duct opening 210 is connected to the sewage pipe. After the floor scrubber is docked with the base station 200, the sewage pipe responds to the suction airflow of the base station air duct opening 210 and is in a negative pressure state, thereby causing the sewage extraction channel 2021 to be in a negative pressure state. The dirt in the sewage collecting chamber 3 enters the sewage pipe through the sewage outlet 31 and the sewage extraction channel 2021 and is discharged through the sewage pipe.

[0218] The base station body is also equipped with a liquid injection port 12 that cooperates with the liquid replenishment port 204. Liquid injection port 12 is used to replenish liquid in the cleaning liquid tank 9. When the floor scrubber is docked with the base station 200, if the cleaning liquid tank 9 is low on liquid or empty, the liquid injection port 12 will replenish the cleaning liquid tank 9. The liquid injection port 12 can be connected to a municipal water source or a liquid storage container 205. When the liquid injection port 12 is connected to the liquid storage container 205, the base station body must also be equipped with the liquid storage container 205.

[0219] The liquid injection port 12 is provided on the outer protrusion 230. Regarding the position of the liquid injection port 12, as shown in Figure 29, in one case, the liquid injection port 12 is located inside the base station air duct opening 210. At this time, the liquid replenishing port 204 is correspondingly located inside the first docking port 11; in another case, as shown in Figure 32, the liquid injection port 12 is located outside the base station air duct opening 210 and is adjacent to the base station air duct opening 210. At this time, the liquid replenishing port 204 is located outside the first docking port 11 and is adjacent to the first docking port 11.

[0220] FIG30 is a schematic diagram of base station 200 equipped with both storage box 2022 and liquid storage container 205; FIG31 is a schematic diagram of base station 200 equipped with only storage box 2022. Of course, base station 200 may also be equipped without storage box 2022 and liquid storage container 205, and only with sewage extraction channel 2021 and liquid injection port 12. In this case, sewage extraction channel 2021 is connected to the sewage pipe, and liquid injection port 12 is connected to the municipal water source.

[0221] In this embodiment, a first charging terminal 270 is provided on the housing of the base station 200. The first charging terminal 270 is located near or on the protruding portion 230. The housing of the floor scrubber is also provided with a second charging terminal 170 that cooperates with the first charging terminal 270. When the floor scrubber is docked with the base station 200, the first charging terminal 270 and the second charging terminal 170 abut and conduct electricity.

[0222] The above are only preferred embodiments of the present disclosure and are not intended to limit the patent scope of the present disclosure. Any equivalent structures made using the contents of the present disclosure and the drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present disclosure.
