[0052] As shown in FIG1 , the cleaning system 10 of the present application is briefly described below.

[0053] According to the present application, the cleaning system 10 includes a base station 100 and a cleaning device 200. The cleaning device 200 can be docked at the base station 100. The base station 100 can be used to place the cleaning device 200 and can also clean the cleaning device 200 to remove the sewage in the cleaning device 200. At the same time, the cleaning device 200 can be rinsed and a sufficient amount of clean water can be stored for the cleaning device 200 for subsequent use of the cleaning device 200.

[0054] Specifically, the cleaning device 200 can be connected to the base station 100, and the base station 100 can clean or charge the cleaning device 200, such as adding water or charging. The sewage generated by the cleaning device 200 after cleaning can be discharged into the sewage tank 110 of the base station 100, or the base station 100 is used to discharge the sewage generated by cleaning the cleaning device 200 into the sewage tank 110.

[0055] In some embodiments of the present application, as shown in Figure 1, the base station 100 may include a first sewage extraction port (not shown in the figure), and the cleaning equipment 200 may include a water tank 210 and a second sewage extraction port. The water tank 210 can be used to collect dirty liquid generated during the cleaning process of the cleaning equipment 200 or store clean water for cleaning. When the cleaning equipment 200 is docked at the base station 100, the water tank 210 and the sewage tank 110 are connected through the docking of the first sewage extraction port and the second sewage extraction port, so that the sewage collected by the cleaning equipment 200 can be pumped to the sewage tank 110 of the base station 100.

[0056] The base station 100 according to an embodiment of the present application is described below with reference to Figures 1 to 4. The base station 100 can generally be used for cleaning equipment 200. The base station 100 can clean or charge the cleaning device, for example, adding water or charging the cleaning equipment 200, and the sewage generated by the cleaning equipment 200 after cleaning can be discharged into the base station 100. The base station 100 can discharge the sewage into a sewer or sewage discharge point. Furthermore, the base station 100 can have a sewage discharge module, which can be used for the discharge of sewage. The sewage discharge module can have a sewage discharge channel (not shown in the figure). The sewage in the base station 100 can be discharged through the sewage discharge channel, and the sewage discharge channel can have an open state and a closed state. When the sewage discharge channel is in the open state, the sewage can be discharged to the outside of the base station 100 through the sewage discharge channel. When the sewage discharge channel is in the closed state, the interior of the base station 100 is in a closed state and the sewage no longer flows.

[0057] In some embodiments of the present application, as shown in Figures 2 and 3, the sewage tank 110 may include a housing 111 and a soft rubber seal (not shown). The bottom end of the housing 111 may be provided with a drain port 1111. The drain port 1111 has an open state and a closed state, and the drain port 1111 may be connected to a drain channel. Specifically, a drain module may be provided below the sewage tank 110 and fixedly connected to the sewage tank 110. When the drain port 1111 is in the open state, the sewage in the sewage tank 110 may flow into the drain channel through the drain port 1111. The drain port 1111 may be provided at the bottom of the housing 111, allowing the sewage to flow to the bottom of the sewage tank 110 under the influence of gravity and be discharged. Therefore, placing the drain port 1111 in the above position facilitates the drainage of sewage. The drain channel is connected to the drain port 1111, so that the sewage in the housing 111 can be drained into the drain channel for discharge. A soft rubber seal can be set at the connection between the sewage outlet 1111 and the sewage channel. The soft rubber seal can fit the outer wall of the sewage outlet 1111. The soft rubber seal can be made of a material with high sealing properties. The provision of a soft rubber seal is beneficial to improving the sealing effect of the connection between the sewage tank 110 and the sewage channel.

[0058] In some embodiments of the present application, as shown in Figures 2 and 3, the sewage outlet 1111 can be constructed into a tubular shape extending in the up-down direction to ensure that water is guided to flow from top to bottom to the sewage channel. At the same time, the tubular shape extending in the up-down direction can increase the cross-sectional area of ​​the sewage outlet 1111 so that sewage can be discharged through the sewage outlet 1111, thereby improving the sewage discharge effect. The upper end of the sewage outlet 1111 is connected to the box body 111, which can shorten the flow path, which is beneficial to reducing the space occupied by the sewage outlet 1111 and facilitating the layout of the space.

[0059] In some embodiments of the present application, as shown in Figures 2 and 3, the cross-sectional area of ​​the inner wall of the box body 111 gradually decreases from top to bottom, and an inclined surface extending obliquely is defined on the inner wall of the box body 111. In this way, the inclined surface at the bottom of the box body 111 can guide the sewage at the bottom of the box body 111 to flow downward to the sewage outlet 1111 based on its own gravity, thereby avoiding sewage from remaining at the bottom of the box body 111 and improving the sewage discharge effect.

[0060] In some embodiments of the present application, as shown in FIG2 , the sewage tank 110 may include a cover 112 that is detachable from the sewage outlet 1111. The sewage outlet 1111 may be provided with a mating portion 1112 that mates with the cover 112. When a user needs to manually empty the sewage tank 110, the sewage tank 110 may be removed from the base station 100 and the cover 112 may be assembled onto the mating portion 1112, so that the cover 112 and the mating portion 1112 are sealed together, thereby closing the sewage outlet. When the cleaning device 200 is docked at the base station 100, the water storage tank 210 and the sewage tank 110 are connected through the docking of the first sewage extraction port and the second sewage extraction port, so that the sewage collected by the cleaning device 200 can be pumped into the sewage tank 110 of the base station 100. However, the sewage will not be automatically discharged from the sewage tank 110. In a specific embodiment, the cover body 112 and the matching portion 1112 are threadedly connected and sealed, thereby improving the sealing effect of the sewage outlet 1111 and avoiding the risk of sewage leakage.

[0061] In some embodiments of the present application, as shown in FIG3 , the sewage tank 110 may include a through-hole cover 113 that is detachably mounted from the sewage outlet 1111, and the through-hole cover 113 is adapted for use with the mating portion 1112. When the user needs to clean the sewage tank 110 using an automatic discharge method, the through-hole cover 113 can be assembled onto the mating portion 1112, so that the sewage outlet is in an open state. When the cleaning device 200 is docked at the base station 100, the water storage tank 210 and the sewage tank 110 are connected through the docking of the first sewage extraction port and the second sewage extraction port, so that the sewage collected by the cleaning device 200 can be pumped into the sewage tank 110 of the base station 100, and the sewage can be discharged from the through hole of the through-hole cover 113. By using the through-hole cover 113, the sealing between the sewage outlet 1111 and the sewage discharge module can be improved, preventing sewage from leaking from the interface between the sewage outlet 1111 and the sewage discharge module.

[0062] In some embodiments of the present application, a seal (not shown) may be movably provided inside the sewage outlet 1111, and the seal may be switched between an initial position and an open position. When the seal is in the initial position, the sewage outlet 1111 is in a closed state, and when the seal is in the open position, the sewage outlet 1111 is in an open state. In other words, the seal can open or close the sewage outlet 1111. In the open state, the sewage in the sewage tank 110 can be automatically discharged. In the closed state, the sewage in the sewage tank 110 is not automatically discharged, but can be discharged manually.

[0063] In some embodiments of the present invention, a resistance member (not shown in the figure) may be provided on the sewage discharge channel, and the sealing member may adopt a movable sealing cover body adapted to the resistance member. When the sewage tank 110 is placed on the base station 100, the resistance member abuts against the sealing member, applying a thrust to the sealing member to drive the sealing member to move toward the interior of the sewage tank 110 to an open position, thereby making the sewage discharge port in an open state. When the sewage tank 110 is removed from the base station 100, the sealing member is separated from the resistance member, and the sealing member moves to the initial position toward the exterior of the sewage tank 110 under the action of the reset force of the elastic member, so as to seal with the sewage discharge port 1111, so that the sewage discharge port is in a closed state.

[0064] In some embodiments of the present application, a blocking structure (not shown) may be provided at the position of the sewage outlet 1111 corresponding to the initial position. When the seal moves toward the exterior of the sewage tank 110 to the initial position under the action of the restoring force, the seal abuts the blocking structure and seals against the sewage outlet 1111, thereby improving the sealing stability of the seal. In one specific application, the blocking structure may be a protrusion.

[0065] In some embodiments of the present application, as shown in FIG4 , the base station 100 may further include a first engaging structure 106, and the sewage tank 110 may be provided with a second engaging structure (not shown) that is compatible with the first engaging structure 106. When the sewage tank 110 is placed on the base station 100, the first engaging structure 106 engages with the second engaging structure to lock the sewage tank 110 on the base station 100, thereby keeping the sewage tank 110 and the base station 100 relatively stationary.

[0066] In some embodiments of the present application, as shown in FIG4 , the base station 100 further includes an unlocking member 107, which is connected to the first engaging structure 106. When a user wishes to remove the sewage tank 110 from the base station 100, the user can press the unlocking member 107, which causes the unlocking member 107 to move the first engaging structure 106 under the action of an external force, releasing the engagement between the first engaging structure 106 and the second engaging structure, thereby allowing the sewage tank 110 to be removed from the base station 100.

[0067] In some embodiments of the present application, as shown in FIG1 , the base station 100 may further include a clean water tank 105. The clean water tank 105 may be connected to the sewage tank 110. The water in the clean water tank 105 may flow into the sewage tank 110 to clean the sewage tank 110, or the water in the clean water tank 105 may be used to clean the sewage channel. Specifically, the clean water in the clean water tank 105 may be used to supply the cleaning equipment 200 for cleaning the cleaning equipment 200. The clean water in the clean water tank 105 may also flow into the sewage tank 110 to clean the sewage tank 110. The above structure can fully utilize the water in the clean water tank 105. In this way, clean water can flow from the bottom of the box body 111 of the sewage tank 110 into the sewage channel through the sewage outlet 1111, and take away the sewage remaining at the bottom of the box body 111 and the sewage outlet 1111, thereby achieving the effect of cleaning the sewage tank 110. At the same time, when clean water flows into the sewage channel, it can also clean the sewage channel and the sewer, which is beneficial to improving the sewage discharge environment.

[0068] In some embodiments of the present application, the base station 100 includes a sewage discharge module (not shown in the figure) and a drainage component (not shown in the figure). The drainage component can be used to control the opening or closing of the sewage discharge channel, thereby controlling whether the sewage in the base station 100 is discharged. Furthermore, the drainage component may include a driving member and a switch member. The driving member may be arranged outside the sewage discharge channel, and the switch member may be arranged inside the sewage discharge channel. The driving member may be connected to the switch member, and the driving member may drive the switch member to perform reciprocating motion so that the switch member switches between a first position and a second position. When the switch member is in the first position, the sewage discharge channel is in an open state; when the switch member is in the second position, the sewage discharge channel is in a closed state. The sewage discharge module has a sewage discharge channel. In the open state, the sewage discharge channel is suitable for discharging dirty liquids. In the closed state, the sewage discharge channel is closed.

[0069] In some embodiments of the present application, the angle between the first position and the second position may be α, and the angle α may satisfy: 30°<α<120°. By setting the angle between the first position and the second position within the above range, the distance that the switch element moves between the first position and the second position can be shortened, thereby improving the accuracy of control, ensuring that the switch element can effectively open or close the sewage channel, and ensuring that when the switch element is in the first position, the sewage channel is in an open state, and when the switch element is in the second position, the sewage channel is in a closed state, and the switch element occupies less space when moving, which is conducive to space arrangement.

[0070] The following describes a base station 100 according to a specific embodiment of the present application with reference to Figures 1 to 4.

[0071] According to the base station 100 of the embodiment of the present application, after the cleaning device 200 is cleaned, it can be placed on the base station 100 for water replenishment, sewage extraction, self-cleaning and charging. Specifically, the base station 100 may include a base and a tray 103. The base may include a host 102, a clean water tank 105 and a sewage tank 110. The host 102 can be set at the center of the base to facilitate connection with the cleaning device 200. The clean water tank 105 and the sewage tank 110 can be set on both sides of the host 102 respectively. This structure can facilitate the layout of the space. The clean water in the clean water tank 105 can be used to clean the cleaning device 200 or supply water to the cleaning device 200. A shelf 104 can also be provided on the base. The shelf 104 can be located near one side of the base or near one side of the sewage tank 110. The shelf 104 can be used to place a brush for cleaning. The user can use the cleaning brush to clean the inside of the sewage tank 110, providing convenience for the user to clean. The tray 103 is connected to the lower portion of the base. A receiving cavity may be formed above the tray 103 . The receiving cavity may be used to place a floor brush of the cleaning device 200 to perform cleaning or drying operations on the floor brush.

[0072] In actual use, if the user manually dumps the sewage tank 110, the cover 112 can be assembled onto the mating portion 1112 to seal the drain outlet 1111, thereby closing the drain outlet 1111. The sewage tank 110 can then be removed from the base station 100 to dump the sewage in the sewage tank 110. If the user automatically dumps the sewage in the sewage tank 110, the through-hole cover 113 can be assembled onto the mating portion 1112. When the water level in the sewage tank 110 reaches a preset value, the drive assembly can control the drive member to switch from the closed state to the open state, thereby adjusting the switch member from the second position to the first position. At this time, the sewage in the sewage tank 110 can be discharged through the drain outlet 1111 into the drainage channel, and then discharged from the drainage channel to the sewer.

[0073] In addition, a pump body can be installed between the clean water tank 105 and the sewage tank 110 of the base station 100. If the user automatically cleans the sewage in the sewage tank 110, during the self-cleaning process, after the cleaning device 200 completes the cleaning, the liquid in the clean water tank 105 of the base station 100 needs to be transferred from the clean water tank 105 to the sewage tank 110 of the base station 100 via the pump body. After the water in the sewage tank 110 of the base station 100 reaches a preset level, the driving member is controlled to open the sewage discharge channel, and the water in the sewage tank 110 is flushed into the sewage discharge channel at once, completing the flushing of the sewage tank 110 and the sewage discharge channel.

[0074] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
