[0077] As mentioned in the background technology, existing cleaning systems generally include a host and a base station. The host is used to clean and store dirt on the ground, and the base station can transfer and collect the dirt stored by the host during the cleaning operation. However, the existing base station is not convenient for transferring and collecting the dirt stored by the host, and it is difficult to discharge the dirt in the base station smoothly. To this end, the inventors of this application have designed a new cleaning system, which can solve the problem of the existing base station being inconvenient for transferring and collecting the dirt stored by the host, and difficult to discharge the dirt in the base station smoothly. The cleaning system of this application will be described in detail below with reference to the accompanying drawings.

[0078] See also Figures 1 to 21 As shown, according to an embodiment of the present application, a cleaning system is provided, which includes a host 10 and a base station 20.

[0079] Specifically, the host 10 has a sewage tank 11 and a sewage outlet 12, and the sewage outlet 12 is used to communicate with the sewage tank 11. The base station 20 includes a base station body 21, which has a sewage injection port 211, a sewage discharge port 212, and an installation cavity 201. The installation cavity 201 is provided with a sewage collection box 22 and a gas extraction mechanism 30, and the sewage injection port 211, the sewage discharge port 212, and the gas extraction mechanism 30 are all connected to the sewage collection box 22. The gas extraction mechanism 30 has a first state and a second state. When the host 10 is docked with the base station body 21, the sewage outlet 12 is connected to the sewage injection port 211. When the gas extraction mechanism 30 is in the first state, the gas extraction mechanism 30 is used to vacuum the sewage collection box 22 to form a negative pressure in the sewage collection box 22. When the gas extraction mechanism 30 is in the second state, the gas extraction mechanism 30 is used to pressurize the sewage collection box 22 to increase the gas pressure in the sewage collection box 22.

[0080] In this embodiment, see Figures 5 and 6 As shown, the base station 20 is used in conjunction with a host 10 (such as a floor scrubber, a washing and mopping machine, or a sweeping machine). The base station 20 can not only be used to clean the cleaning parts 14 (roller brush, mop, etc.) on the host 10, but also to add water or charge the host 10. The dirty liquid generated after the host 10 performs the cleaning operation can be discharged into the dirt collection tank 22 of the base station 20. The base station 20 can discharge the dirty liquid from the dirt collection tank 22 into a sewer or sewage discharge area, etc., wherein the dirty liquid can be sewage generated after the host 10 is cleaned or a mixture of sewage and detergent. At the same time, the sewage tank 11 of the host 10 in this embodiment is used to store dirt on the ground, and the sewage collection tank 22 of the base station 20 is used to temporarily store dirt sucked from the host 10.

[0081] When the cleaning system is actually used, the host 10 can be placed on the base station 20, and the sewage outlet 12 of the host 10 can be docked with the sewage injection port 211 of the base station 20, so that the sewage tank 11 is connected to the sewage collecting tank 22, and then the sewage outlet 212 of the base station 20 is connected to the sewer or sewage discharge point, so that the sewage collecting tank 22 is connected to the sewer or sewage discharge point. When it is necessary to pump the sewage in the sewage tank 11 of the main unit 10 into the sewage collecting box 22, the gas pumping mechanism 30 is in the first state, and the gas pumping mechanism 30 pumps out the gas in the sewage collecting box 22 to perform a vacuum operation on the sewage collecting box 22 to form a negative pressure in the sewage collecting box 22, so that the sewage in the sewage tank 11 can enter the sewage injection port 211 from the sewage outlet 12, and then be quickly pumped into the sewage collecting box 22 through the sewage injection port 211; when it is necessary to discharge the sewage in the sewage collecting box 22, the gas pumping mechanism 30 is in the second state, and the gas pumping mechanism 30 inhales gas from the outside and transports the gas into the sewage collecting box 22 to pressurize the sewage collecting box 22 and increase the gas pressure in the sewage collecting box 22, so that the sewage in the sewage collecting box 22 can be quickly discharged to the sewer or sewage discharge point through the sewage outlet 212. The overall structure is simple. The vacuum operation or pressurization operation in the sewage collecting box 22 can be realized by connecting the gas extraction mechanism 30 with the sewage collecting box 22, thereby realizing the rapid suction of sewage on the host 10 by the base station 20 and the rapid and smooth discharge of sewage in the base station 20, effectively improving the suction effect and discharge capacity of the sewage collecting box 22 of the base station 20, and no human intervention is required. It is easy to use and has a high degree of intelligence, which helps to improve the user experience.

[0082] Further, see Figures 7 to 10 As shown, the gas extraction mechanism 30 in this embodiment includes a first base 31, an extraction component 32, a reversing component 33, and an extraction unit 34. The first base 31 is disposed within the mounting cavity 201; the extraction component 32 is disposed within the first base 31 and communicates with the dirt collection box 22; the reversing component 33 is rotatably disposed within the first base 31 to press against the extraction component 32 to switch the gas extraction mechanism 30 between a first state and a second state; and the extraction unit 34 is disposed within the mounting cavity 201 and communicates with the extraction component 32. That is to say, the first base 31 provides a mounting platform for the exhaust component 32 and the reversing component 33; the reversing component 33 rotates relative to the first base 31, so that the gas exhaust mechanism 30 can be switched between the first state and the second state, thereby performing a vacuum operation or a pressurization operation on the dirt collecting box 22; the exhaust component 32 can, under the suction action of the exhaust part 34, suck the gas in the dirt collecting box 22 and discharge it to the outside, or draw the outside gas into the dirt collecting box 22.

[0083] Specifically, when the reversing component 33 presses the pumping component 32 and the gas pumping mechanism 30 is in the first state, the exhaust part 34 extracts the gas in the sewage collecting box 22 and sucks it into the pumping component 32, and then discharges it to the outside through the pumping component 32, thereby forming a negative pressure in the sewage collecting box 22, and then the sewage in the sewage tank 11 of the main unit 10 can be quickly sucked into the sewage collecting box 22; when the reversing component 33 presses the pumping component 32 and the gas pumping mechanism 30 is in the second state, the exhaust part 34 draws the outside gas in through the pumping component 32, and then discharges it into the sewage collecting box 22 through the pumping component 32, so that the sewage collecting box 22 can be pressurized to increase the gas pressure in the sewage collecting box 22, and then the sewage in the sewage collecting box 22 can be discharged to the sewer or sewage discharge point through the sewage outlet 212. The overall structure is simple, which effectively improves the suction capacity of the base station 20 to transfer and collect the waste stored in the host 10 and effectively ensures that the waste in the base station 20 can be discharged smoothly, ensuring the reliability and stability of the base station 20's sewage suction and discharge process.

[0084] Optionally, the exhaust part 34 in this embodiment includes an air pump. Of course, in other embodiments of the present application, the exhaust part 34 may also include other devices with exhaust functions, such as a blower 71, etc. As long as it is other deformation methods based on the conception of this application, it is within the protection scope of this application.

[0085] Further, see Figure 10 As shown, the air extraction portion 34 in this embodiment has an air extraction port 341 and an air exhaust port 342 , and the air extraction and exhaust component 32 includes a first air inlet pipe 321 , a first air exhaust pipe 322 , a second air inlet pipe 323 and a second air exhaust pipe 324 . The first and second exhaust pipes 322 are connected to the exhaust port 342 and the outside world respectively; the second and second exhaust pipes 323 are connected to the exhaust port 341 and the outside world respectively; the second and second exhaust pipes 324 are connected to the exhaust port 342 and the dirt collecting box 22 respectively; when the gas extraction mechanism 30 is in the first state, the reversing component 33 presses against the second air intake pipe 323 and the second exhaust pipe 324 to disconnect the second air intake pipe 323 and the second exhaust pipe 324, and connects the first air intake pipe 321 and the first exhaust pipe 322; when the gas extraction mechanism 30 is in the second state, the reversing component 33 presses against the first air intake pipe 321 and the first exhaust pipe 322 to disconnect the first air intake pipe 321 and the first exhaust pipe 322, and connects the second air intake pipe 323 and the second exhaust pipe 324.

[0086] Specifically, the gas exhaust mechanism 30 in this embodiment is in the first state, which means that the reversing component 33 moves to the second air inlet pipe 323 and the second exhaust pipe 324 and presses the second air inlet pipe 323 and the second exhaust pipe 324, so that the second air inlet pipe 323 and the second exhaust pipe 324 are disconnected, while the first air inlet pipe 321 and the first exhaust pipe 322 are not pressed by the reversing component 33 and can connect the air extraction port 341 and the exhaust port 342. At this time, the vacuum operation of the dirt collecting box 22 can be performed by utilizing the cooperation of the vacuum section 34, the first air inlet pipe 321 and the first exhaust pipe 322. That is, when the vacuum section 34 is working, the gas in the dirt collecting box 22 is sucked into the first air inlet pipe 321, and then enters the vacuum section 34 and is transported to the exhaust port 342 through the vacuum port 341, and then discharged into the first exhaust pipe 322 through the exhaust port 342, and finally discharged through the first exhaust pipe 322, thereby finally realizing the vacuum operation of the dirt collecting box 22, and effectively improving the suction effect of the dirt collecting box 22 of the base station 20.

[0087] Specifically, the gas exhaust mechanism 30 in this embodiment is in the second state, which means that the reversing component 33 moves to the first air inlet pipe 321 and the first exhaust pipe 322 and presses the first air inlet pipe 321 and the first exhaust pipe 322, so that the first air inlet pipe 321 and the first exhaust pipe 322 are disconnected, while the second air inlet pipe 323 and the second exhaust pipe 324 are not pressed by the reversing component 33 and can connect the air extraction port 341 and the exhaust port 342. At this time, the exhaust section 34 can be used in conjunction with the second air inlet pipe 323 and the second exhaust pipe 324 to pressurize the sewage collecting box 22. That is, when the exhaust section 34 is working, the external gas is sucked into the second air inlet pipe 323, and then enters the exhaust section 34 and is transported to the exhaust port 342 through the exhaust port 341, and then discharged into the second exhaust pipe 324 through the exhaust port 342, and finally discharged into the sewage collecting box 22 through the second exhaust pipe 324, thereby finally realizing the pressurization operation of the sewage collecting box 22 and effectively improving the discharge capacity of the sewage collecting box 22 of the base station 20.

[0088] Further, see Figures 8 and 9 As shown, the reversing component 33 in this embodiment includes a transmission wheel 331 and a first driving unit 332. The transmission wheel 331 is rotatably mounted on the first base 31. The first driving unit 332 is mounted on the first base 31 and is drivingly connected to the transmission wheel 331 to drive the transmission wheel 331 to press against the second air inlet pipe 323 and the second air outlet pipe 324 to place the gas extraction mechanism 30 in the first state, or to press against the first air inlet pipe 321 and the second air outlet pipe 324 to place the gas extraction mechanism 30 in the second state. In this embodiment, the first driving unit 332 illustratively includes a drive motor.

[0089] Specifically, the first driving part 332 can serve as the power source of the reversing component 33, providing power for the transmission wheel 331, so that the transmission wheel 331 can be pressed against the second air inlet pipe 323 and the second exhaust pipe 324 to put the gas pumping mechanism 30 in the first state, thereby putting the second air inlet pipe 323 and the second exhaust pipe 324 in a disconnected state, and putting the first air inlet pipe 321 and the first exhaust pipe 322 in a connected state, or, the rotating wheel can be pressed against the first air inlet pipe 321 and the first exhaust pipe 322 to put the gas pumping mechanism 30 in the second state, thereby putting the first air inlet pipe 321 and the first exhaust pipe 322 in a disconnected state, and putting the second air inlet pipe 323 and the second exhaust pipe 324 in a connected state. That is to say, when the first driving part 332 is working, the first driving part 332 drives the transmission wheel 331 to rotate, thereby driving the transmission wheel 331 to switch between pressing against the first air intake pipe 321, the first exhaust pipe 322 and pressing against the second air intake pipe 323, the second exhaust pipe 324, so as to realize the opening or closing of the first air intake pipe 321 and the first exhaust pipe 322, or the second air intake pipe 323 and the second exhaust pipe 324, thereby effectively improving the reliability and stability of the reversing component 33.

[0090] Further, see Figure 8 As shown, an eccentric shaft 3311 is provided on the transmission wheel 331 in this embodiment. The eccentric shaft 3311 is set away from the geometric center of the transmission wheel 331. The eccentric shaft 3311 is connected to the output shaft of the first driving part 332, so that the transmission wheel 331 rotates eccentrically around the eccentric shaft 3311 under the drive of the first driving part 332 and presses against the first intake pipe 321 and the first exhaust pipe 322 or the second intake pipe 323 and the second exhaust pipe 324.

[0091] Specifically, the transmission wheel 331 in this embodiment is provided with an eccentric shaft 3311. This allows the transmission wheel 331 to be precisely moved to different positions under the drive of the first drive unit 332, thereby pressing against the first air inlet pipe 321 and the first air outlet pipe 322 or the second air inlet pipe 323 and the second air outlet pipe 324, effectively ensuring stable switching between the first and second states of the gas extraction mechanism 30. Furthermore, the provision of the eccentric shaft 3311 enables rapid movement of the transmission wheel 331, which, to a certain extent, improves the response speed of the reversing component 33, allowing the gas extraction mechanism 30 to complete the switching between the first and second states in a relatively short period of time.

[0092] Furthermore, the first base 31 in this embodiment is provided with a position recognition unit (not shown in the drawings), which is connected to the transmission wheel 331 to identify the position of the transmission wheel 331. Specifically, the position recognition unit can detect the position or movement state of the transmission wheel 331. When the transmission wheel 331 is driven by the first driving unit 332 to rotate to the second air inlet pipe 323 and the second exhaust pipe 324 to abut against the second air inlet pipe 323 and the second exhaust pipe 324, or rotates to the first air inlet pipe 321 and the first exhaust pipe 322 to abut against the first air inlet pipe 321 and the first exhaust pipe 322, the position recognition unit will be triggered, thereby sending a corresponding signal to identify the position of the transmission wheel 331. Exemplarily, the position recognition unit in this embodiment includes a micro switch.

[0093] Further, see Figure 5 、 Figure 11 as well as Figure 12 As shown, in this embodiment, a sewage injection pipe 23 and a sewage discharge pipe 24 are provided within the installation cavity 201. The sewage injection pipe 23 is connected between the sewage injection port 211 and the sewage collection box 22. A first on-off mechanism 40 is provided on the sewage injection pipe 23. The sewage discharge pipe 24 is connected between the sewage discharge port 212 and the sewer. A second on-off mechanism 50 is provided on the sewage discharge pipe 24. When the gas extraction mechanism 30 is in a first state, the first on-off mechanism 40 is in a connected state, allowing sewage in the sewage tank 11 to be pumped into the sewage collection box 22 via the sewage discharge port 12, the sewage injection port 211, and the sewage injection pipe 23, while the second on-off mechanism 50 is in a disconnected state. When the gas extraction mechanism 30 is in a second state, the second on-off mechanism 50 is in a connected state, allowing sewage in the sewage collection box 22 to be discharged into the sewer via the sewage discharge port 212 and the sewage discharge pipe 24, while the first on-off mechanism 40 is in a disconnected state.

[0094] Specifically, before using the gas extraction mechanism 30 to vacuum the sewage collection box 22, it is necessary to first close the first on-off mechanism 40 and the second on-off mechanism 50 so that the first on-off mechanism 40 and the second on-off mechanism 50 are both in the off state, and then open the gas extraction mechanism 30, so that the gas extraction mechanism 30 can be in the first state under the mutual cooperation of the extraction component 32, the reversing component 33 and the suction part 34, and then the sewage collection box 22 can be vacuumed to form a negative pressure in the sewage collection box 22. Subsequently, the first on-off mechanism 40 can be opened to quickly suck the sewage in the sewage tank 11 of the host 10 into the sewage collection box through the sewage outlet 12, the sewage injection port 211 and the sewage injection pipe 23. The first on-off mechanism 40 only needs to be closed, and the gas extraction mechanism 30 and the second on-off mechanism 50 are turned on. The gas extraction mechanism 30 can be in the second state with the cooperation of the extraction component 32, the reversing component 33 and the air extraction part 34, thereby pressurizing the sewage collecting box 22 and increasing the gas pressure in the sewage collecting box 22. Finally, the sewage in the sewage collecting box 22 is quickly discharged to the sewer or sewage discharge through the sewage outlet 212 and the sewage pipe 24, thereby effectively improving the discharge capacity of the sewage collecting box 22 of the base station 20 and ensuring the smooth discharge of sewage.

[0095] In other words, by providing the sewage injection pipe 23 and sewage discharge pipe 24, this embodiment ensures that the cleaning system effectively manages the collection and discharge of sewage. When needed, sewage can be quickly pumped from the sewage tank 11 of the main unit 10 to the sewage collection tank 22 of the base station 20, or discharged into a sewer or sewage outlet, thereby improving sewage treatment efficiency. Furthermore, the provision of the second on-off mechanism 50 in this embodiment ensures that sewage in the sewage collection tank 22 does not flow out when discharge is not required, thereby preventing environmental pollution to a certain extent.

[0096] Further, see Figures 13 and 14As shown, the first on-off mechanism 40 in this embodiment includes a second base 41, a slide rail 42, a clamping block 43, a cam 44 and a second driving part 45. The second base 41 is arranged in the installation cavity 201, and the second base 41 has a through hole 401 for the sewage injection pipe 23 to pass through; the slide rail 42 is arranged on the second base 41 and extends along the length direction of the second base 41; the clamping block 43 is movably mounted on the slide rail 42; the cam 44 is rotatably arranged on the second base 41 and is rotatably connected to the clamping block 43; the second driving part 45 is arranged on the second base 41 and is driven and connected to the cam 44. The second driving part 45 drives the cam 44 to rotate to drive the clamping block 43 to reciprocate along the length direction of the slide rail 42, so that the clamping block 43 has a first position of closing the sewage injection pipe 23 and a second position of opening the sewage injection pipe 23. Exemplarily, the second driving part 45 in this embodiment includes a driving motor. It should be noted that the "length direction of the second base 41" in this embodiment refers to the attached Figure 14 The direction indicated by the letter X

[0097] Specifically, when the first on-off mechanism 40 needs to be closed to enable the gas extraction mechanism 30 to be in the first state or the second state, the second driving unit 45 is activated, and the second driving unit 45 drives the cam 44 to rotate clockwise or counterclockwise. The rotation of the cam 44 drives the pressing block 43 to slide on the slide rail 42, thereby driving the pressing block 43 to the first position, thereby pressing the sewage injection pipe 23 to disconnect the sewage injection pipe 23. When the first on-off mechanism 40 needs to be opened to pump sewage from the sewage tank 11 of the host 10 into the sewage collection tank 22 of the base station 20, the second driving unit 45 is activated and driven to rotate counterclockwise or clockwise. The rotation of the cam 44 drives the pressing block 43 to slide on the slide rail 42, thereby driving the pressing block 43 to the second position, thereby moving away from the sewage injection pipe 23 to open the sewage injection pipe 23. It can be seen that the first on-off mechanism 40 in this embodiment has a simple structure and is convenient for opening and closing the sewage injection pipe 23.

[0098] It should be noted that, in this embodiment, the second driving part 45 may drive the cam 44 to rotate clockwise so that the clamping block 43 is in the first position, and the second driving part 45 drives the cam 44 to rotate counterclockwise so that the clamping block 43 is in the second position. Alternatively, the second driving part 45 drives the cam 44 to rotate counterclockwise so that the clamping block 43 is in the first position, and the second driving part 45 drives the cam 44 to rotate clockwise so that the clamping block 43 is in the second position. This application does not make specific limitations here.

[0099] Optionally, the cam 44 in this embodiment includes an Archimedean spiral cam 44 , which has a simple structure, is easy to assemble and disassemble, and reduces manufacturing costs. At the same time, the setting of the Archimedean spiral cam 44 facilitates driving the pressing block 43 to switch between the first position and the second position.

[0100] Further, see Figures 15 to 17 As shown, the second on-off mechanism 50 in this embodiment includes a cover plate 51, a first transmission bracket 53 and a third driving part 55. The cover plate 51 is rotatably arranged on the sewage collecting box 22 through a rotating shaft 52, and the cover plate 51 has a third position of rotating around the rotating shaft 52 to close the sewage outlet 212 and a fourth position of opening the sewage outlet 212; the first transmission bracket 53 is movably arranged on the sewage collecting box 22, and the first transmission bracket 53 has a mounting groove 503, in which a rack 531 extending along the first direction and a gear 54 meshing with the rack 531 and sleeved on the rotating shaft 52 are arranged; the third driving part 55 is arranged on the sewage collecting box 22 and is drivingly connected to the first transmission bracket 53 to drive the first transmission bracket 53 to reciprocate along the first direction, so that the cover plate 51 switches between the third position and the fourth position. Exemplarily, the third driving part 55 in this embodiment includes a linear motor. It should be noted that the "first direction" in this embodiment refers to the attached Figure 16 The direction indicated by the letter Y

[0101] Specifically, since the cover plate 51 in this embodiment is sleeved on the rotating shaft 52, and the rotating shaft 52 is sleeved with a gear 54 that meshes with the rack 531, when it is necessary to close the second on-off mechanism 50 to place the gas extraction mechanism 30 in the first state or to pump the sewage in the sewage tank 11 of the host 10 into the sewage collection tank 22, the third driving unit 55 is turned on, and the third driving unit 55 drives the first transmission bracket 53 to move in the first direction, thereby driving the gear 54 to rotate clockwise or counterclockwise under the movement of the rack 531, and then driving the rotating shaft 52 to rotate, and then driving the cover plate 51 to rotate around the rotating shaft 52 to be in the third position, thereby closing the sewage outlet 212. At this time, the sewage in the sewage collection box 22 cannot be discharged from the sewage outlet 212; when it is necessary to open the second on-off mechanism 50 to discharge the sewage in the sewage collection box 22, the third driving part 55 is opened, and the third driving part 55 drives the first transmission bracket 53 to move in the first direction, thereby driving the gear 54 to rotate counterclockwise or clockwise under the movement of the rack 531, and then driving the rotating shaft 52 to rotate, and then driving the cover plate 51 to rotate about the rotating shaft 52 to be in the fourth position and open the sewage outlet 212. At this time, the sewage in the sewage collection box 22 can be quickly discharged from the sewage outlet 212 to the sewer or sewage discharge point under the pressurized action of the gas extraction mechanism 30. It can be seen that the second on-off mechanism 50 in this embodiment has a simple structure and is convenient for opening and closing the sewage outlet 212.

[0102] It should be noted that, in this embodiment, the third driving part 55 may drive the first transmission bracket 53 to move to drive the gear 54 to rotate clockwise so that the cover 51 is in the third position, and the third driving part 55 drives the first transmission bracket 53 to move to drive the gear 54 to rotate counterclockwise so that the cover 51 is in the fourth position. Alternatively, the third driving part 55 drives the first transmission bracket 53 to move to drive the gear 54 to rotate counterclockwise so that the cover 51 is in the third position, and the third driving part 55 drives the first transmission bracket 53 to move to drive the gear 54 to rotate clockwise so that the cover 51 is in the fourth position. This application does not make specific limitations here.

[0103] Further, see Figures 16 and 17 As shown, in this embodiment, the first transmission bracket 53 is provided with at least one first limiting protrusion 532. The second on-off mechanism 50 also includes a second transmission bracket 56, which is movably mounted on the third driving portion 55. The second transmission bracket 56 is provided with at least two second limiting protrusions 561 spaced apart along the first direction, with at least one first limiting protrusion 532 engaging between two adjacent second limiting protrusions 561. The third driving portion 55 drives the second transmission bracket 56 to reciprocate in the first direction, thereby driving the first transmission bracket 53 to reciprocate in the first direction, thereby switching the cover plate 51 between the third position and the fourth position.

[0104] Specifically, in this embodiment, a first limiting protrusion 532 is engaged between two limiting protrusions. When the third driving portion 55 drives the second transmission bracket 56 to reciprocate in the first direction, the second limiting protrusion 561 applies an external force to the first limiting protrusion 532, causing the first transmission bracket 53 to move in the same direction as the second transmission bracket 56. This causes the rack 531 on the first transmission bracket 53 to cooperate with the gear 54, thereby driving the rotation of the rotating shaft 52. It can be seen that the arrangement of the first limiting protrusion 532 and the second limiting protrusion 561 in this embodiment facilitates the movement of the first transmission bracket 53, thereby enabling the opening and closing of the cover plate 51 and ultimately the opening and closing of the sewage outlet 212. The overall structure is simple and the operation is convenient and quick.

[0105] Further, see Figure 3 、 Figure 5 、 Figure 6 as well as Figure 12 As shown, the host 10 in this embodiment has a first clean water tank 15 and a water inlet 13, which is used to communicate with the first clean water tank 15. The base station body 21 has a water injection port 213 and a cleaning tank 26. A second clean water tank 25 is provided in the installation cavity 201. The water injection port 213 and the cleaning tank 26 are both used to communicate with the second clean water tank 25. When the host 10 and the base station body 21 are docked, the water injection port 213 is connected to the water inlet 13.

[0106] Specifically, in this embodiment, the second clean water tank 25 can be connected to the outside world (e.g., a tap water pipe), so that clean water from the outside can be input into the second clean water tank 25. The clean water in the second clean water tank 25 flows in two ways. One way of clean water enters the water inlet 13 through the water inlet 213 to automatically replenish the first clean water tank 15, ensuring that there is sufficient water in the first clean water tank 15 for the main unit 10 to perform floor cleaning or other operations. The other way of clean water is transported from the second clean water tank 25 to the cleaning tank 26 for soaking and cleaning the main unit 10 in the cleaning tank 26, effectively ensuring the cleaning effect of the cleaning tank 26.

[0107] Specifically, see Figure 5 As shown, in this embodiment, a pressure reducing valve 80 and a solenoid valve 90 are provided on the pipeline connecting the second clean water tank 25 to the outside world, wherein the pressure reducing valve 80 is used to reduce the pressure of the fluid in the pipeline, that is, no matter how the inlet pressure of the pressure reducing valve 80 changes, the pressure reducing valve 80 can ensure that the outlet pressure is within a stable range, effectively ensuring the stability of the cleaning system; the solenoid valve 90 is used to control the flow rate, pressure and flow direction of the fluid in the pipeline, thereby realizing the control and regulation of water inlet to the base station 20 in the cleaning system.

[0108] Specifically, as shown in the figure, the second clean water tank 25 in this embodiment is equipped with a floating member 100 and a water level detector 110. The floating member 100 includes a mechanical float, a common liquid level control device that controls the liquid level through the principle of buoyancy. As the liquid level rises or falls, the mechanical float rises or falls accordingly, activating the corresponding switch or valve, thereby controlling the amount of water entering the second clean water tank 25. The water level detector 110 helps monitor the water level in the second clean water tank 25, allowing for timely water replenishment and ensuring normal water supply for the cleaning system.

[0109] Further, see Figure 5 As shown, at least one water inlet channel 27 is provided in the base station body 21 in this embodiment, and at least one water inlet channel 27 is connected to the second clean water tank 25 and / or the cleaning tank 26. A heating element 28 is provided on at least one water inlet channel 27, and the heating element 28 is at least used to heat the fluid in the at least one water inlet channel 27. Such a configuration facilitates increasing the temperature of the fluid, so that the higher temperature fluid can better dissolve grease or stains, effectively improving the cleaning effect of the base station 20 on the host 10. By way of example, the heating element 28 in this embodiment includes a heating wire or a heating plate and other structures, which are not specifically limited in this application. As long as they are other variations based on the concept of this application, they are within the scope of protection of this application.

[0110] Optionally, the water inlet channel 27 in this embodiment can be set to one, or can be set to two or more, which is not specifically limited in this application.

[0111] Understandably, see Figure 5 As shown, in the embodiment shown in the present application, at least one water inlet channel 27 can connect the second clean water tank 25 and the cleaning tank 26, so as to facilitate the fluid in the second clean water tank 25 to be transported to the cleaning tank 26; of course, in an embodiment not shown in the present application, at least one water inlet channel 27 can connect the second clean water tank 25 with the external pipeline, so as to facilitate the external pipeline to directly transport fluid to the second clean water tank 25; in addition, in an embodiment not shown in the present application, at least one water inlet channel 27 can connect the cleaning tank 26 with the external pipeline, so as to facilitate the external pipeline to directly transport fluid to the cleaning tank 26.

[0112] Further, see Figure 2 as well as Figure 18 As shown, in this embodiment, at least two air inlets 261 are provided in the cleaning tank 26, and the at least two air inlets 261 are respectively located on two opposite sides of the cleaning tank 26 along the second direction; a ventilation component 60 and a drying component 70 are provided in the base station body 21, and a ventilation duct 61 is provided in the ventilation component 60, and the ventilation duct 61 is connected to the air inlet 261. The drying component 70 is installed in the ventilation duct 61 so that the drying airflow generated by the drying component 70 is transmitted to the air inlet 261 along the ventilation duct 61. It should be noted that the "second direction" in this embodiment refers to the attached Figure 2 The direction indicated by the letter Z.

[0113] Specifically, after the host 10 returns to the base station 20, the cleaning member 14 (such as a roller or mop, etc.) of the host 10 is located in the cleaning tank 26. After the cleaning member 14 is cleaned in the cleaning tank 26, a drying airflow (i.e., hot airflow) is provided to at least two air inlets 261 in the cleaning tank 26 through the drying component 70, and air can be blown and baked on two opposite sides of the cleaning member 14 along the second direction at the same time, thereby fully drying the cleaning member 14 in a short time, effectively improving the drying efficiency of the cleaning member 14. At the same time, this embodiment can install the drying component 70 in the ventilation duct 61, so that the drying airflow generated by the drying component 70 can be transmitted along the ventilation duct 61 to the air inlet 261, making assembly efficient and convenient. Optionally, the direction of the ventilation duct 61 in this embodiment only needs to be reasonably arranged according to the position of the corresponding air inlet 261.

[0114] Further, see Figure 2 as well as Figure 12As shown, the base station body 21 in this embodiment includes a base 214 and a cover 215. The base 214 is provided with a receiving groove 202, and the ventilation component 60 is installed in the receiving groove 202. The cover 215 is buckled on the receiving groove 202, and the cleaning groove 26 is provided on the outer side of the cover 215 away from the receiving groove 202. In this embodiment, the cleaning groove 26 can be obtained by punching out a pit matching the shape of the cleaning member 14 at the position where the cleaning groove 26 is required to be provided on the cover 215, which is convenient for processing. When assembling the base station 20 in this embodiment, the ventilation component 60 equipped with the drying component 70 is installed in the receiving groove 202, and the cover 215 is connected to the installation groove 503 to complete the assembly of the base station 20, which is efficient and convenient to assemble.

[0115] Furthermore, the air inlet 261 in this embodiment includes a first air inlet 2611 and a second air inlet 2612, and the first air inlet 2611 and the second air inlet 2612 are respectively located on two opposite sides of the cleaning tank 26 along the second direction. Figures 20 to 21 As shown, the ventilation duct 61 in this embodiment includes a first ventilation section 611, a second ventilation section 612 and a third ventilation section 613. Among them, the ventilation component 60 includes a first shell 62, a first partition 63 and a second shell 64. A groove is provided on the first shell 62 (not shown in the drawings), the first partition 63 is provided on the side of the groove close to the cleaning tank 26, the second shell 64 is buckled on the groove, and the second shell 64 and the inner wall surface of the groove and the first partition 63 are surrounded to form the first ventilation section 611, the second ventilation section 612 and the third ventilation section 613. Secondly, a notch is respectively provided on the side of the second ventilation section 612 and the third ventilation section 613 close to the cover body 215. After the second shell 64 is buckled on the groove, it is surrounded with the corresponding notch to form an air outlet 601. Specifically, in order to enable the ventilation component 60 to be socketed with the connecting protrusion 2151 on the cover body 215, the first shell 62 and the second shell 64 are both provided with a socket flange 66 on the outer peripheral wall close to the cover body 215, and the socket flange 66 on the second shell 64 and the socket flange 66 on the first shell 62 are arranged to form an air outlet 601, which is convenient for assembly.

[0116] The second ventilation section 612 and the third ventilation section 613 are closer to the washing tank 26 than the first ventilation section 611 and are respectively connected to the first ventilation section 611. The drying component 70 is mounted on the first ventilation section 611, with the second ventilation section 612 connected to the first air outlet 2611, and the third ventilation section 613 connected to the second air outlet 2612. Thus, after generating a dry air flow in the first ventilation section 611, the drying component 70 in this embodiment splits the generated dry air flow into two paths, entering the second ventilation section 612 and the third ventilation section 613, respectively, and then transmitting the dry air flow to the first air outlet 2611 and the second air outlet 2612 through the second ventilation section 612 and the third ventilation section 613, respectively. It can be seen that the ventilation component 60 in this embodiment has three ventilation sections, and the drying airflow is respectively transmitted to the corresponding air inlet 261 through two ventilation sections (i.e., the second ventilation section 612 and the third ventilation section 613). Compared with the method of simultaneously supplying air to the air inlet 261 through a larger channel, this structure of supplying air to the corresponding air inlet 261 through two smaller ventilation sections will make the transmission speed of the drying airflow faster when the volume flow rate of the airflow generated by the drying component 70 is constant, so that the airflow entering the air inlet 261 and blowing onto the cleaning component 14 is stronger, and the drying effect on the cleaning component 14 is better.

[0117] Furthermore, a vent 6101 is provided on one side of the first ventilation section 611 away from the cleaning tank 26. Figure 21 As shown, the drying component 70 may specifically include a fan 71 and a heating element 72. The fan 71 is installed at the vent 6101 so that the fan 71 can guide the outside air into the ventilation duct 61. The fan 71 includes an air supply port (not shown in the drawings), which is located on the side of the fan 71 close to the cleaning tank 26. The heating element 72 is installed between the air supply port and the first partition 63. The heating element 72 is used to heat the air blown by the fan 71 and transmit the heated air flow to the second ventilation section 612 and the third ventilation section 613. Since the heating element 72 is located between the air supply port of the fan 71 and the first partition 63, that is, located at the connection between the second ventilation section 612 and the third ventilation section 613 and the first ventilation section 611, the heating element 72 can promptly transmit the heated air flow to the second ventilation section 612 and the third ventilation section 613.

[0118] Specifically, see Figure 21As shown, the length of the heating element 72 in this embodiment extends along the second direction and blocks the connection between the second and third ventilation sections 612 and 613 and the first ventilation section 611. To ensure that the air delivered to the heating element 72 by the fan 71 is more uniform, thereby enabling the heating element 72 to efficiently and fully heat the air from the fan 71, the ventilation component 60 in this embodiment also includes a second baffle 65. The second baffles 65 comprise at least three of them. The at least three second baffles 65 are installed spaced apart along the second direction within the first ventilation section 611 and between the air outlet and the heating element 72. Multiple flow paths are formed between adjacent second baffles 65 and between the second baffles 65 and the inner wall of the recess of the first housing 62. The fan 71 delivers air along these multiple flow paths to the heating element 72, ensuring that all portions of the heating element 72 along the second direction receive and heat the air promptly, thereby improving the heating efficiency of the heating element 72.

[0119] The heating element 72 in this embodiment may include at least one of a resistance wire heater, a ceramic heater, a quartz heater, and a positive temperature coefficient thermistor heater. Among them, the resistance wire heater uses a metal wire (usually a nickel-chromium alloy or an iron-chromium-aluminum alloy) as a heating element, and an electric current passes through these metal wires to generate heat during the heating period. The ceramic heater is a device that uses the resistance characteristics of ceramic materials to generate heat by heating ceramic elements with electric current. Ceramic heaters have the characteristics of fast heating and high efficiency. The quartz heater contains a resistance wire or other heating element inside and is enclosed in a quartz tube. They can heat up quickly and reach a very high temperature. The positive temperature coefficient thermistor heater is referred to as a PTC heater (PTC is the abbreviation of Positive Temperature Coefficient). The PTC heater uses a special ceramic material. The resistance of this material increases as the temperature rises, thereby automatically adjusting the power output to avoid overheating. Optionally, the heating element 72 in this embodiment is preferably a PTC heater.

[0120] When the air in the sewage tank 11 of the main unit 10 is exhausted, the air in the sewage tank 22 is exhausted to the outside.

[0121] When it is necessary to discharge sewage from the sewage collecting box 22, the gas exhaust mechanism 30 is in the second state, and the first driving part 332 drives the transmission wheel 331 to rotate to press against the first air inlet pipe 321 and the first exhaust pipe 322 so that the first air inlet pipe 321 and the first exhaust pipe 322 are in a disconnected state. At this time, the exhaust part 34 is opened, and the external gas enters from the second air inlet pipe 323 under the suction action of the exhaust part 34 and is pumped to the exhaust port 341, and then transported to the exhaust port 342 through the exhaust port 341, and then discharged to the second exhaust pipe 324 through the exhaust port 342, and finally the gas is transported to the sewage collecting box 22 by the second exhaust pipe 324, and finally the gas is transported to the sewage collecting box 22, thereby realizing the pressurization operation of the sewage collecting box 22, thereby increasing the pressure in the sewage collecting box 22, and then the sewage in the sewage collecting box 22 can be quickly discharged to the sewer or sewage discharge.

[0122] The overall structure of the base station 20 of the present application is simple. By switching the connection state between the gas extraction mechanism 30 and the sewage collecting box 22, rapid suction and rapid discharge of sewage can be achieved, which effectively improves the suction effect and discharge capacity of the sewage collecting box 22 of the base station 20. It does not require human intervention, is easy to use, and has a high degree of intelligence, which helps to improve the user experience.

[0123] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0124] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
