It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0047] As mentioned in the background technology, when the sewage in the sewage bucket of the existing floor scrubber accumulates to a certain extent, the floor scrubber needs to be put back into the base station to discharge the sewage in the sewage bucket into the sewage tank of the base station, but the sewage tank of the existing base station has a poor sewage pumping effect, and it is difficult to discharge the sewage pumped into the sewage tank. To this end, the inventor of the present application has designed a new base station, which can improve the sewage tank's effect on sewage suction and discharge. The base station of the present 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 through the vent 111 and the reversing component 22 in sequence 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 transports gas to the accommodating chamber through the vent 111 under the action of the exhaust part 21 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 washing and mopping machine, or a sweeping machine). The base station 50 can not only be used to clean the cleaning parts (roller brush, mop, etc.) on the cleaning robot 60, but also can be used to add water or charge the cleaning robot 60, and 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 the sewer or sewage discharge place, etc., wherein the dirty liquid can be the 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 the substances sucked from the cleaning robot 60, and the vent 111 of the sewage tank 11 is used for air intake or air outlet.

[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 is 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 with the sewer or sewage discharge. When it is necessary to pump the sewage on the cleaning robot 60 into the sewage tank 11, the reversing component 22 is in the first state, the air extraction part 21 extracts the gas in the accommodating chamber through the vent 111, and discharges the gas through the reversing component 22, so as to vacuum the accommodating chamber to form a negative pressure in the accommodating chamber, so that the sewage on the cleaning robot 60 can be quickly pumped into the accommodating chamber; when it is necessary to discharge the sewage from the accommodating chamber, the reversing component 22 is in the second state, the air extraction part 21 inhales the gas through the reversing component 22, and transmits the gas to the accommodating chamber through the vent 111, so as to pressurize the accommodating chamber and discharge the sewage in the accommodating chamber quickly to the sewer or sewage discharge, etc. The overall structure is simple, and rapid suction and rapid discharge of sewage can be achieved by switching the connection between the reversing component 22 and the sewage tank 11, which effectively improves the suction effect and discharge capacity of the sewage tank 11 of the base station 50 for sewage, and does not require human intervention. It is easy to use and has a high degree of intelligence, 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 under the conception of the present application, it is within the protection scope of the present 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 disposed on the base 23 so that the reversing assembly 22 can be switched between a first state and a second state; the pumping component 25 is disposed on the base 23 and connected between the air extraction 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, so that the reversing assembly 22 can be switched between the first state and the second state, thereby vacuuming or pressurizing the accommodating chamber; the pumping component 25 can, under the suction action of the air extraction 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 which time the air pumping unit 21 draws the gas in the accommodating chamber into the pumping and discharging unit 25 through the vent 111, and then discharges it to the outside through the pumping and discharging unit 25, so that negative pressure is formed in the accommodating chamber, and then the sewage on the cleaning robot 60 can be sucked into the accommodating chamber; when the reversing component 24 moves to the second position, the reversing assembly 22 is in the second state, at which time the air pumping unit 21 draws the outside gas into the accommodating chamber through the pumping and discharging unit 25, and then discharges it into the accommodating chamber through the pumping and discharging unit 25 and the vent 111, so that the accommodating chamber is pressurized, and then the sewage in the accommodating chamber can be discharged to the sewer or sewage discharge place, etc. The overall structure is simple, which effectively improves the sewage suction effect and discharge capacity of the sewage tank 11 of the base station 50, and improves the flexibility of the reversing assembly 22 to a certain extent, 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 part 21 in this embodiment has an air extraction port 211 and an exhaust port 212, and the exhaust component 25 includes a first pipeline group 251 and a second pipeline group 252, and 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 exhaust port 212. When the reversing component 22 is in the first state, the reversing component 24 is pressed against the second pipeline group 252 to make the second pipeline group 252 in a disconnected state, and the first pipeline group 251 in a connected state; when the reversing component 22 is in the second state, the reversing component 24 is pressed against the first pipeline group 251 to make the first pipeline group 251 in a disconnected state, and the second pipeline group 252 in a connected state.

[0057] Specifically, the reversing assembly 22 in this embodiment is in the first state, which means that the reversing component 24 moves to the first position to press the second pipeline group 252, so that the second pipeline group 252 is disconnected, and the first pipeline group 251 is not pressed by the reversing component 24 and can connect the air extraction port 211 and the exhaust port 212. At this time, the cooperation between the air extraction part 21 and the first pipeline group 251 can be used to evacuate the accommodating chamber, that is, when the air extraction part 21 is working, the gas in the accommodating chamber is sucked into the first pipeline group 251 through the vent 111, and 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 by the first pipeline group 251.

[0058] Specifically, the reversing assembly 22 in this embodiment is in the second state, which means that the reversing component 24 moves to the second position to press the first pipeline group 251, so that the first pipeline group 251 is disconnected, and the second pipeline group 252 is not pressed by the reversing component 24 and can connect the air extraction port 211 and the exhaust port 212. At this time, the cooperation between the air extraction part 21 and the second pipeline group 252 can be used to pressurize the accommodating chamber, that is, when the air extraction part 21 is working, the external gas is sucked into the second pipeline group 252, and then transported to the exhaust port 212 through the air extraction port 211, and then discharged to the second pipeline 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 group 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 respectively connected to the vent 111 and the air extraction port 211, and the opposite ends of the first exhaust pipe 2512 are respectively connected to the exhaust port 212 and the outside. When the reversing assembly 22 is in the first state, the first pipeline group 251 is in a connected state, and the gas in the accommodating chamber is discharged to the outside 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, so as to vacuum the accommodating chamber. In this way, a negative pressure can be formed in the accommodating chamber, so that the sewage in the cleaning robot 60 can be quickly sucked into the accommodating chamber, effectively improving the suction effect of the sewage 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 pipeline group 252 in this embodiment includes a second air inlet pipe 2521 and a second exhaust pipe 2522, and the opposite ends of the second air inlet pipe 2521 are respectively connected to the air extraction port 211 and the outside, and the opposite ends of the second exhaust pipe 2522 are respectively connected to the exhaust port 212 and the vent 111. When the reversing assembly 22 is in the second state, the second pipeline group 252 is in a connected state, and the external gas passes through the second air inlet pipe 2521, the air extraction port 211, the exhaust port 212, the second exhaust pipe 2522 and the vent 111 in sequence to enter the accommodating chamber to pressurize the accommodating chamber. In this way, the pressure in the accommodating chamber can be increased, so that the sewage in the accommodating chamber can be quickly discharged to the sewer or sewage discharge place, etc., effectively improving the drainage capacity of the sewage tank 11 of the base station 50, and to a certain extent, avoiding the sewage from flowing back into the sewage tank 11, thereby increasing the sewage discharge efficiency of the base station 50.

[0061] Further, see Figures 1 to 4 As shown, in this embodiment, the first pipeline group 251 includes a first air inlet pipe 2511 and a first exhaust pipe 2512, and the second pipeline group 252 includes a second air inlet pipe 2521 and a second exhaust pipe 2522. The base 23 is covered with a cover plate 40, and the cover plate 40 has an inlet and outlet pipe 41, an air extraction pipe 42 and an exhaust pipe 43. Among them, one end of the first air inlet pipe 2511 connected to the air vent 111 and one end of the second exhaust pipe 2522 connected to the air vent 111 are connected to the air vent 111 through the inlet and outlet pipe 41; one end of the first air inlet pipe 2511 connected to the air extraction port 211 and one end of the second air inlet pipe 2521 connected to the air extraction port 211 are connected to the air extraction port 211 through the air extraction pipe 42; one end of the first exhaust pipe 2512 connected to the exhaust port 212 and one end of the second exhaust pipe 2522 connected to the exhaust port 212 are connected to the exhaust port 212 through the 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 driving motor 242. The transmission wheel 241 is rotatably disposed on the base 23; the driving motor 242 is disposed on the base 23 and is drivingly connected to the transmission wheel 241, so as to drive the transmission wheel 241 to press against the second pipeline group 252 to put the reversing component 22 in the first state, or to press against the first pipeline group 251 to put the reversing component 22 in the second state.

[0063] Specifically, the drive motor 242 can serve as a power source for 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, thereby making the second intake pipe 2521 and the second exhaust pipe 2522 in a disconnected state, while the first intake pipe 2511 and the first exhaust pipe 2512 are in a connected state, or making the transmission wheel 241 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, thereby making the first intake pipe 2511 and the first exhaust pipe 2512 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 driving motor 242 is working, the driving 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 can eccentrically rotate around the eccentric shaft 2411 under the drive of the driving motor 242 and press 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 accurately moved to different positions under the drive of the driving motor 242, so as to be pressed against the first pipeline group 251 or the second pipeline group 252, effectively ensuring the stable switching of the reversing component 22 between the first state and the second state. At the same time, the provision of the eccentric shaft 2411 enables the transmission wheel 241 to move quickly, which improves the response speed of the reversing component 24 to a certain extent, so that the reversing component 22 can complete the switching between the first state and the second state in a relatively short time.

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

[0067] In combination with the above-mentioned 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 a disconnected state. At this time, the suction part 21 is opened, and the gas in the accommodating chamber is extracted from the vent 111 and sucked into the first air inlet pipe 2511 under the suction action of the suction part 21, and then transported to the exhaust port 212 through the suction port 211, and then discharged to the first exhaust pipe 2512 through the exhaust port 212, and finally the gas is discharged to the outside by the first exhaust pipe 2512, and finally the vacuum operation of the accommodating chamber is realized, 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 suction part 21 is opened, and the external gas enters from the second air inlet pipe 2521 under the suction action of the suction part 21 and is pumped to the suction port 211, and then is transported to the exhaust port 212 through the suction port 211, and then is discharged to the second exhaust pipe 2522 through the exhaust port 212, and finally the second exhaust pipe 2522 transports the gas to the accommodating chamber through the vent 111, and finally realizes 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, which effectively improves the suction effect and discharge capacity of the sewage tank 11 of the base station 50. It does not require human intervention, is easy to use, and has a high degree of intelligence, which helps to improve the user experience.

[0070] On the other hand, see Fig. 9 As shown, the embodiment of the present application further provides a cleaning system, which includes the above-mentioned base station, and 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.

[0071] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. 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 figure. For example, if the device in the accompanying 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 only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
