[0044] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0047] As mentioned in the background technology, when the wastewater in the wastewater bucket of an existing floor scrubber accumulates to a certain level, the floor scrubber needs to be returned to the base station to drain the wastewater in the wastewater bucket into the base station's wastewater tank. However, the wastewater pumping efficiency of the existing base station's wastewater tank is poor, and it is difficult to discharge the wastewater pumped into the tank. To address this issue, the inventors of this application have designed a new base station that can improve the wastewater suction and discharge efficiency of the wastewater tank. The base station of this application will be described in detail below with reference to the accompanying drawings.

[0048] See also Figures 1 to 8 As shown, according to an embodiment of the present application, a base station 50 is provided, which includes a base 10 and an exhaust mechanism 20.

[0049] Specifically, the base 10 is provided with a sewage tank 11, which has a accommodating cavity (not shown in the drawings) and a vent 111, and the accommodating cavity is communicated with the vent 111; the exhaust mechanism 20 is provided on the base 10 and connected to the vent 111, and the exhaust mechanism 20 includes an exhaust part 21 and a reversing component 22, and the exhaust part 21 is connected to the vent 111 through the reversing component 22.

[0050] Among them, the reversing component 22 has a first state and a second state. When the reversing component 22 is in the first state, the gas in the accommodating chamber is discharged in sequence through the vent 111 and the reversing component 22 under the action of the exhaust part 21 to vacuum the accommodating chamber; when the reversing component 22 is in the second state, the reversing component 22 is under the action of the exhaust part 21 to transport gas to the accommodating chamber through the vent 111 to pressurize the accommodating chamber.

[0051] In this embodiment, the base station 50 is used in conjunction with a cleaning robot 60 (such as a floor scrubber, a washer-mop machine, or a sweeper). The base station 50 can not only be used to clean the cleaning components (roller brush, mop, etc.) on the cleaning robot 60, but can also perform operations such as adding water or charging the cleaning robot 60. In addition, the dirty liquid generated by the cleaning robot 60 after performing the cleaning operation can be discharged into the sewage tank 11 of the base station 50. The sewage tank 11 of the base station 50 can discharge the dirty liquid into a sewer or sewage discharge area, etc., wherein the dirty liquid can be sewage generated by the cleaning robot 60 after cleaning or a mixture of sewage and detergent. At the same time, the accommodating cavity of the sewage tank 11 in this embodiment is used to temporarily store substances sucked from the cleaning robot 60, and the vent 111 of the sewage tank 11 is used for air intake or exhaust.

[0052] When the base station 50 is actually used, the cleaning robot 60 can be placed on the base station 50, and the sewage outlet of the cleaning robot 60 can be docked with the inlet of the sewage tank 11 of the base station 50, so that the outlet of the sewage tank 11 of the base station 50 is connected to a sewer or sewage discharge. When the sewage from the cleaning robot 60 needs to be pumped into the sewage tank 11, the reversing assembly 22 is in a first state, and the air extraction unit 21 extracts the gas in the accommodating chamber through the vent 111 and discharges the gas through the reversing assembly 22, thereby vacuuming the accommodating chamber and forming a negative pressure in the accommodating chamber, thereby quickly pumping the sewage from the cleaning robot 60 into the accommodating chamber. When the sewage needs to be discharged from the accommodating chamber, the reversing assembly 22 is in a second state, and the air extraction unit 21 draws gas through the reversing assembly 22 and delivers the gas into the accommodating chamber through the vent 111, thereby pressurizing the accommodating chamber and quickly discharging the sewage in the accommodating chamber to the sewer or sewage discharge. The overall structure is simple, and rapid suction and discharge of sewage can be achieved by switching the connection between the reversing component 22 and the sewage tank 11, effectively improving the suction effect and discharge capacity of the sewage tank 11 of the base station 50 for sewage, without the need for human intervention, easy to use, and highly intelligent, which helps to improve the user experience.

[0053] Optionally, the exhaust part 21 in this embodiment includes an air pump. Of course, in other embodiments of the present application, the exhaust part 21 may also include other devices with exhaust functions, such as a blower, 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.

[0054] Further, see Figures 1 to 5 As shown, the reversing assembly 22 in this embodiment includes a base 23, a reversing component 24, and a pumping component 25. The base 23 is mounted on the base 10; the reversing component 24 is rotatably mounted on the base 23 to switch the reversing assembly 22 between a first state and a second state; the pumping component 25 is mounted on the base 23 and connected between the exhaust portion 21 and the vent 111. In other words, the base 23 provides a mounting platform for the reversing component 24 and the pumping component 25; the reversing component 24 rotates relative to the base 23, enabling the reversing assembly 22 to switch between the first state and the second state, thereby evacuating or pressurizing the accommodating chamber; and the pumping component 25 can, under the suction action of the exhaust portion 21, suck the gas in the accommodating chamber and discharge it to the outside, or suck the gas from the outside and discharge it into the accommodating chamber.

[0055] Specifically, when the reversing component 24 moves to the first position, the reversing assembly 22 is in the first state. At this time, the air extraction unit 21 draws the gas in the accommodating chamber into the exhaust component 25 through the vent 111, and then discharges it to the outside through the exhaust component 25, thereby forming a negative pressure in the accommodating chamber, thereby sucking the sewage on the cleaning robot 60 into the accommodating chamber. When the reversing component 24 moves to the second position, the reversing assembly 22 is in the second state. At this time, the air extraction unit 21 draws the outside gas into the accommodating chamber through the exhaust component 25, and then discharges it into the accommodating chamber through the exhaust component 25 and through the vent 111, thereby pressurizing the accommodating chamber and discharging the sewage in the accommodating chamber into a sewer or sewage discharge point. The overall structure is simple, effectively improving the sewage suction effect and discharge capacity of the sewage tank 11 of the base station 50, and to a certain extent improving the flexibility of the reversing assembly 22, ensuring the reliability of the sewage suction and discharge process of the base station 50.

[0056] Further, see Figure 1 as well as Figure 8 As shown, the air extraction portion 21 in this embodiment has an air extraction port 211 and an air exhaust port 212, and the air extraction component 25 includes a first pipeline group 251 and a second pipeline group 252. The first pipeline group 251 and the second pipeline group 252 are both connected to the vent 111, the air extraction port 211, and the air exhaust port 212. When the reversing assembly 22 is in the first state, the reversing component 24 abuts against the second pipeline group 252 to disconnect the second pipeline group 252 and connect the first pipeline group 251; when the reversing assembly 22 is in the second state, the reversing component 24 abuts against the first pipeline group 251 to disconnect the first pipeline group 251 and connect the second pipeline group 252.

[0057] Specifically, the reversing assembly 22 in this embodiment is in the first state when the reversing component 24 moves to the first position to press against the second pipeline group 252, thereby disconnecting the second pipeline group 252, while the first pipeline group 251 is not pressed by the reversing component 24 and can communicate with the air extraction port 211 and the exhaust port 212. At this time, the cooperation between the air extraction unit 21 and the first pipeline group 251 can be used to evacuate the accommodating chamber. That is, when the air extraction unit 21 is in operation, the gas in the accommodating chamber is sucked into the first pipeline group 251 through the vent 111, then transported to the exhaust port 212 through the air extraction port 211, and then discharged to the first pipeline group 251 through the exhaust port 212, and finally discharged to the outside through the first pipeline group 251.

[0058] Specifically, the reversing assembly 22 in this embodiment is in the second state when the reversing component 24 moves to the second position to press against the first pipe group 251, thereby disconnecting the first pipe group 251 and allowing the second pipe group 252 to communicate with the air extraction port 211 and the exhaust port 212 without being pressed by the reversing component 24. At this time, the cooperation between the air extraction unit 21 and the second pipe group 252 can be utilized to pressurize the accommodating chamber. That is, when the air extraction unit 21 is in operation, external gas is sucked into the second pipe group 252, then transported to the exhaust port 212 through the air extraction port 211, and then discharged to the second pipe group 252 through the exhaust port 212, and finally enters the accommodating chamber through the vent 111.

[0059] Further, see Figure 1 、 Figure 2 、 Figure 5 as well as Figure 8 As shown, the first pipeline assembly 251 in this embodiment includes a first air inlet pipe 2511 and a first exhaust pipe 2512. The opposite ends of the first air inlet pipe 2511 are connected to the vent 111 and the air extraction port 211, respectively. The opposite ends of the first exhaust pipe 2512 are connected to the exhaust port 212 and the outside world, respectively. When the reversing assembly 22 is in the first state, the first pipeline assembly 251 is in a connected state. Gas within the accommodating chamber is discharged to the outside world through the vent 111, the first air inlet pipe 2511, the air extraction port 211, the exhaust port 212, and the first exhaust pipe 2512 in sequence, thereby evacuating the accommodating chamber. This creates a negative pressure within the accommodating chamber, allowing wastewater in the cleaning robot 60 to be quickly drawn into the accommodating chamber, effectively improving the suction efficiency of the wastewater tank 11 of the base station 50.

[0060] Further, see Figure 1 、 Figure 2 、 Figure 5 as well as Figure 8 As shown, the second pipe assembly 252 in this embodiment includes a second air inlet pipe 2521 and a second air outlet pipe 2522. The opposite ends of the second air inlet pipe 2521 are connected to the air extraction port 211 and the outside world, respectively. The opposite ends of the second air outlet pipe 2522 are connected to the air outlet port 212 and the vent 111, respectively. When the reversing assembly 22 is in the second state, the second pipe assembly 252 is in a connected state. External air passes through the second air inlet pipe 2521, the air extraction port 211, the air outlet port 212, the second air outlet pipe 2522, and the vent 111, sequentially entering the accommodating chamber to pressurize the accommodating chamber. This increases the pressure within the accommodating chamber, allowing wastewater within the accommodating chamber to be quickly discharged to a sewer or sewage outlet, effectively improving the drainage capacity of the sewage tank 11 of the base station 50 and, to a certain extent, preventing wastewater from flowing back into the sewage tank 11, thereby increasing the sewage drainage efficiency of the base station 50.

[0061] Further, see Figures 1 to 4 As shown, in this embodiment, the first pipe assembly 251 includes a first air inlet pipe 2511 and a first air outlet pipe 2512, and the second pipe assembly 252 includes a second air inlet pipe 2521 and a second air outlet pipe 2522. A cover plate 40 is provided on the base 23. The cover plate 40 has an inlet and outlet pipe 41, an air extraction pipe 42, and an air exhaust pipe 43. The first air inlet pipe 2511 and the second air outlet pipe 2522 are both connected to the air vent 111 via the inlet and outlet pipe 41. The first air inlet pipe 2511 and the second air outlet pipe 2521 are both connected to the air extraction port 211 via the air extraction pipe 42. The first air outlet pipe 2512 and the second air outlet pipe 2522 are both connected to the air exhaust port 212 via the air exhaust pipe 43.

[0062] Further, see Figure 1 、 Figure 5 as well as Figure 7 As shown, the reversing component 24 in this embodiment includes a transmission wheel 241 and a drive motor 242. The transmission wheel 241 is rotatably mounted on the base 23; the drive motor 242 is mounted on the base 23 and is drivingly connected to the transmission wheel 241, so as to drive the transmission wheel 241 to abut against the second pipeline assembly 252 to place the reversing assembly 22 in the first state, or to abut against the first pipeline assembly 251 to place the reversing assembly 22 in the second state.

[0063] Specifically, the drive motor 242 can serve as the power source of the reversing component 24, providing power for the transmission wheel 241, so that the transmission wheel 241 can be pressed against the second intake pipe 2521 and the second exhaust pipe 2522 of the second pipeline group 252 to put the reversing component 22 in the first state, and then the second intake pipe 2521 and the second exhaust pipe 2522 are in a disconnected state, while the first intake pipe 2511 and the first exhaust pipe 2512 are in a connected state, or the transmission wheel 241 can be pressed against the first intake pipe 2511 and the first exhaust pipe 2512 of the first pipeline group 251 to put the ventilation component in the second state, and then the first intake pipe 2511 and the first exhaust pipe 2512 are in a disconnected state, while the second intake pipe 2521 and the second exhaust pipe 2522 are in a connected state. That is to say, when the drive motor 242 is working, the drive motor 242 drives the transmission wheel 241 to rotate, thereby driving the transmission wheel 241 to switch between pressing against the second pipeline group 252 and pressing against the first pipeline group 251, so as to realize the opening or closing of the first pipeline group 251 and the second pipeline group 252, effectively improving the reliability and stability of the reversing component 24.

[0064] Further, see Figure 5 as well as Figure 7 As shown, an eccentric shaft 2411 is provided on the transmission wheel 241 in this embodiment. The eccentric shaft 2411 is set away from the geometric center of the transmission wheel 241. The eccentric shaft 2411 is connected to the output shaft of the driving motor 242, so that the transmission wheel 241 rotates eccentrically around the eccentric shaft 2411 under the drive of the driving motor 242 and presses against the first pipeline group 251 or the second pipeline group 252.

[0065] Specifically, the transmission wheel 241 in this embodiment is provided with an eccentric shaft 2411, which enables the transmission wheel 241 to be precisely moved to different positions under the drive of the drive motor 242, thereby abutting against the first pipeline group 251 or the second pipeline group 252, effectively ensuring stable switching between the first and second states of the reversing assembly 22. Furthermore, the provision of the eccentric shaft 2411 enables rapid movement of the transmission wheel 241, which, to a certain extent, improves the response speed of the reversing component 24, allowing the reversing assembly 22 to complete the switching between the first and second states in a relatively short period of time.

[0066] Further, see Figure 3 As shown, the base 23 in this embodiment is provided with a position recognition unit 30, which is connected to the transmission wheel 241 to identify the position of the transmission wheel 241. Specifically, the position recognition unit 30 can detect the position or motion state of the transmission wheel 241. When the transmission wheel 241 is driven by the drive motor 242 to rotate to the first position to abut against the second pipeline group 252 or to rotate to the second position to abut against the first pipeline group 251, the position recognition unit 30 is triggered, thereby sending a corresponding signal to identify the position of the transmission wheel 241. Exemplarily, the position recognition unit 30 in this embodiment includes a micro switch.

[0067] In combination with the above embodiments, it can be known that in the present application, when it is necessary to pump the sewage on the cleaning robot 60 into the sewage tank 11, the reversing assembly 22 is in the first state, and the driving motor 242 drives the transmission wheel 241 to rotate to press against the second pipeline group 252 so that the second air inlet pipe 2521 and the second exhaust pipe 2522 are in the disconnected state. At this time, the air extraction part 21 is opened, and the gas in the accommodating chamber is extracted from the vent 111 under the suction action of the air extraction part 21 and is sucked into the first air inlet pipe 2511, and then transported to the exhaust port 212 through the air extraction port 211, and then discharged to the first exhaust pipe 2512 through the exhaust port 212, and finally discharged to the outside by the first exhaust pipe 2512, thereby finally realizing the vacuum operation of the accommodating chamber, thereby forming a negative pressure in the accommodating chamber, and then the sewage on the cleaning robot 60 can be quickly sucked into the accommodating chamber.

[0068] When it is necessary to discharge the sewage from the accommodating chamber, the reversing assembly 22 is in the second state, and the driving motor 242 drives the transmission wheel 241 to rotate to press against the first pipeline group 251 so that the first air inlet pipe 2511 and the first exhaust pipe 2512 are in a disconnected state. At this time, the exhaust part 21 is opened, and the external gas enters from the second air inlet pipe 2521 under the suction action of the exhaust part 21 and is pumped to the exhaust port 211, and then transported to the exhaust port 212 through the exhaust port 211, and then discharged to the second exhaust pipe 2522 through the exhaust port 212, and finally the second exhaust pipe 2522 transports the gas into the accommodating chamber through the vent 111, finally realizing the pressurization operation of the accommodating chamber, thereby increasing the pressure in the accommodating chamber, and then the sewage in the accommodating chamber can be quickly discharged to the sewer or sewage discharge.

[0069] The overall structure of the base station 50 of the present application is simple. By switching the connection state between the reversing component 22 and the sewage tank 11, rapid suction and rapid discharge of sewage can be achieved, effectively improving the suction effect and discharge capacity of the sewage tank 11 of the base station 50 for sewage, without the need for human intervention, easy to use, and highly intelligent, which helps to improve the user experience.

[0070] On the other hand, see Figure 9 As shown, the embodiment of the present application further provides a cleaning system, which includes the above-mentioned base station. Therefore, the cleaning system includes all the technical effects of the above-mentioned base station. Since the technical effects of the base station have been described in detail above, they will not be repeated here.

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.

[0072] 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.

[0073] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
