Description

Technical Field

[0001] The present disclosure relates to the technical field of cleaning equipment, and particularly to a cleaning base station. Background Art

[0002] Environmental hygiene is an important factor affecting the quality of life. Therefore, along with the continuous improvement of people's requirements for the quality of life, the corresponding requirements for environmental hygiene are also getting higher and higher. As a result, many floor cleaning devices have emerged, such as vacuum cleaners, sweepers, and floor washers. A floor washer is a cleaning machine that cleans the floor while sucking up sewage and taking the sewage away from the site.

[0003] In existing floor washers, there is generally a solution bucket for storing cleaning solution and a sewage bucket for collecting sewage after cleaning. Among them, to pour out the sewage in the sewage bucket, the user needs to personally remove the lid of the sewage bucket and then drain the sewage through the upper end of the opening of the sewage bucket. Such an operation is relatively laborious, and the user may come into contact with dirt, which greatly affects the user experience.

[0004] Therefore, a cleaning system with a cleaning base station has emerged on the market. The floor washer can cooperate with the cleaning base station to drain the sewage in the internal sewage bucket, and some cleaning base stations can also clean cleaning components such as mops of the floor washer.

[0005] However, the position of the blockage sensor in the existing cleaning base station during the sewage discharge process is not set reasonably, and frequent alarms and false alarms are likely to occur, which greatly affects the user experience. Summary of the Utility Model

[0006] The present disclosure provides a cleaning base station to solve the problems existing in the prior art.

[0007] According to a first aspect of the present disclosure, there is provided a cleaning base station configured to dock with a cleaning device. The cleaning base station includes:

[0008] A base configured to extend in the height direction;

[0009] A sewage discharge groove provided with a sewage receiving port for docking with a sewage discharge port of the cleaning device;

[0010] A blockage sensor disposed at a detection position of the sewage discharge groove, the blockage sensor being configured to be triggered when a sewage discharge blockage occurs at the detection position;

[0011] Wherein, the volume inside the base station below the detection position is configured to be greater than 80% of the volume of the sewage bucket of the cleaning device.

[0012] In one embodiment of the present disclosure, the sewage discharge tank includes a sewage holding part and a sewage receiving part communicating with the inner cavity of the sewage holding part; the detection position is located in the inner cavity of the sewage holding part; wherein, the volume of the sewage discharge tank above the detection position is configured to be greater than the volume of the sewage bucket, and the volume above the detection position includes the part of the sewage holding part above the detection position and the part of the sewage receiving part above the detection position.

[0013] In one embodiment of the present disclosure, the top of the sewage receiving part is configured to form a sewage receiving opening extending outward from the sewage holding part, the opening direction of the sewage receiving opening is configured to face upward, and is configured to be docked with the sewage discharge port of the cleaning device; the volume above the detection position includes the sewage holding part and the part of the sewage receiving part from the detection position to the sewage receiving opening.

[0014] In one embodiment of the present disclosure, the top end face of the sewage receiving opening is configured to be lower than the top of the sewage holding part.

[0015] In one embodiment of the present disclosure, the sewage receiving part is connected to one side of the sewage holding part, the sewage receiving part has a sewage discharge surface extending to communicate with the inner cavity of the sewage holding part, and at least part of the dirt flowing out of the sewage discharge port is configured to flow from the sewage discharge surface to the inner cavity of the sewage holding part; the detection position is configured to be set on the side of the sewage holding part far from the sewage discharge surface.

[0016] In one embodiment of the present disclosure, the detection position is configured to be not lower than the bottom end of the sewage discharge surface.

[0017] In one embodiment of the present disclosure, the volume of the sewage discharge tank above the detection position is configured to be greater than the volume of the sewage discharge tank below the detection position.

[0018] In one embodiment of the present disclosure, the volume of the cleaning base below the detection position is 0.8 times to 1.2 times the volume of the sewage bucket.

[0019] In one embodiment of the present disclosure, it further includes:

[0020] A control unit, which is configured to send an alarm message based on the electrical signal triggered by the blockage sensor.

[0021] In one embodiment of the present disclosure, the sewage discharge tank includes a sewage holding part, the sewage holding part includes a gradually expanding part with a gradually increasing cross-sectional area from top to bottom and a gradually shrinking part with a gradually decreasing cross-sectional area from top to bottom, the gradually expanding part is docked above the gradually shrinking part, and the detection position is located at the docking place of the bottom end of the gradually expanding part and the gradually shrinking part.

[0022] The present disclosure provides a cleaning base station configured to dock with a cleaning device, and includes a base, a sewage tank, and a blockage sensor. The base is configured to extend in the height direction. The sewage tank is provided with a sewage receiving port for docking with the sewage outlet of the cleaning device. The blockage sensor is disposed at a detection position of the sewage tank and is configured to be triggered when a sewage blockage occurs at the detection position. Wherein, the volume inside the base station below the detection position is configured to be greater than 80% of the volume of the sewage bucket of the cleaning device.

[0023] During the operation of the cleaning base station of the present disclosure, the floor brush assembly of the cleaning device is placed on the tray, the sewage outlet of the cleaning device will be docked with the sewage receiving port on the sewage tank, and the dirt in the sewage bucket will flow into the sewage tank. Since the blockage sensor is disposed in the sewage tank and can be triggered when the liquid level of the dirt in the sewage tank reaches the detection position, in this way, when the cleaning base station of the present disclosure is blocked and the liquid level of the dirt in the sewage tank reaches the detection position, the blockage sensor can be triggered in time, which is convenient for the cleaning base station of the present disclosure to accelerate sewage discharge, so as to remove the blocked dirt in the sewage pipeline or perform other subsequent steps.

[0024] And since the volume inside the cleaning base station below the detection position is greater than 80% of the volume of the sewage bucket, even when the sewage discharge volume is large, the dirt is not easy to accumulate at the detection position, thus effectively avoiding false alarms.

[0025] Other features and advantages of the present disclosure will become clear through the following detailed description of the exemplary embodiments of the present disclosure with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The present disclosure provides a cleaning base station configured to dock with a cleaning device and includes a base, a sewage discharge tank, and a blockage sensor. The base is configured to extend in the height direction; the sewage discharge tank is provided with a sewage receiving port for docking with the sewage discharge port of the cleaning device; the blockage sensor is disposed at a detection position of the sewage discharge tank and is configured to be triggered when a sewage blockage occurs at the detection position; wherein, the volume inside the base station below the detection position is configured to be greater than 80% of the volume of the sewage bucket of the cleaning device.

[0055] During the operation of the cleaning base station of the present disclosure, the floor brush assembly of the cleaning device is placed on the tray, the sewage discharge port of the cleaning device will be docked with the sewage receiving port on the sewage discharge tank, and the dirt in the sewage bucket will flow into the sewage discharge tank. Since the blockage sensor is disposed in the sewage discharge tank and can be triggered when the liquid level of the dirt in the sewage discharge tank reaches the detection position, in this way, when the cleaning base station of the present disclosure is blocked and the liquid level of the dirt in the sewage discharge tank reaches the detection position, the blockage sensor can be triggered in time, facilitating the cleaning base station of the present disclosure to accelerate sewage discharge, thereby removing the blocked dirt in the sewage pipeline or performing other subsequent steps.

[0056] Since the volume below the detection position in the cleaning base station is greater than 80% of the volume of the sewage bucket, even when the sewage discharge is large, dirt is not likely to accumulate at the detection position, thus effectively avoiding false alarms.

[0057] For ease of understanding, the following will refer to Figures 1 to 21 , and in conjunction with an embodiment, the specific structure and working principle of the cleaning base station 10 of the present disclosure will be described in detail. It should be noted that the present disclosure also provides a cleaning base station 10. For the sake of brevity, the cleaning system will be introduced together when describing the cleaning base station 10.

[0058] As Figures 1 to 6 shown, the present disclosure provides a cleaning base station 10, which is used to cooperate with a cleaning device 90 for cleaning work.

[0059] As Figure 1 and Figure 2 shown, the cleaning device 90 is used to clean work surfaces such as floors and carpets. The cleaning device 90 and the cleaning base station 10 can be docked with each other so that the cleaning device 90 can discharge sewage into the cleaning base station 10. Moreover, the cleaning base station 10 can also charge the cleaning device 90, replenish cleaning liquid, etc., which will not be elaborated here.

[0060] Specifically, as Figure 1 and Figure 2 shown, the cleaning device 90 at least includes a body 91 and a sewage bucket 92. It can be understood that the cleaning device 90 may also include a floor brush assembly 94 and a cleaning liquid bucket. Among them, the body 91 serves as a carrier for installing various functional elements required by the cleaning device 90.

[0061] The floor brush assembly 94 is arranged at the bottom end of the body 91 and is used to clean work surfaces such as floors, carpets or furniture surfaces. A rotating shaft can be provided between the floor brush assembly 94 and the body 91, and the body 91 can rotate relative to the floor brush assembly 94 through the rotating shaft. When the body 91 rotates backward to an inclined position away from the floor brush assembly 94, it is convenient for the user to drag the cleaning device 90 back and forth to achieve the purpose of cleaning the work surface; when the body 91 rotates forward from the inclined position away from the floor brush assembly 94 to an upright position, the cleaning device 90 can be parked on the work surface, or as Figure 1 , Figure 2 shown, the cleaning device 90 can be placed on the cleaning base station 10. When cleaning the work surface, the floor brush assembly 94 is always attached to the work surface. The floor brush assembly 94 may include a floor brush housing and a floor brush rotatably connected to the floor brush housing; the floor brush can rotate relative to the work surface to wipe the stains on the work surface. As shown in the figure, a sewage suction pipe is provided inside the part of the body 91 connected to the floor brush assembly 94, and the bottom end of the sewage suction pipe is communicated with the sewage suction port provided at the floor brush assembly 94.

[0062] The sewage bucket 92 is used to hold the dirt sucked from the working surface. The dirt can be the sewage generated by cleaning or can also include various kinds of garbage sucked from the working surface. A sewage discharge port 93 and a sewage inlet are provided at the bottom of the sewage bucket 92. Among them, the sewage discharge port 93 of the sewage bucket 92 is used to dock with the cleaning base station 10, so as to discharge the dirt in the inner cavity of the sewage bucket 92 into the cleaning base station 10.

[0063] Specifically, as Figures 1 to 6 shown, the cleaning base station 10 includes a base 1, a tray 2 and a sewage discharge groove 3; the base 1 is configured to extend in the height direction and is used to install various functional components required for the cleaning base station 10 such as the sewage discharge groove 3.

[0064] The tray 2 is arranged at the bottom of the base 1 and extends forward along the horizontal direction relative to the base 1. The side opposite to the front side is denoted as the rear side. The tray 2 is mainly used to carry the floor brush assembly 94 of the cleaning base station 10 when the cleaning device 90 docks with the cleaning base station 10 for sewage discharge, and can also be used to clean the floor brush assembly 94 of the cleaning device 90, etc. or charge the cleaning base station 10. That is, it can be understood that the floor brush assembly 94 is located on the tray 2 during sewage discharge.

[0065] The sewage discharge groove 3 includes a sewage holding part 31 located inside the cleaning base station 10 and a sewage receiving part 32 communicating with the inner cavity of the sewage holding part 31; the sewage receiving part 32 is located in front of the sewage holding part 31 and is configured to be connected to the side wall of the sewage holding part 31 to enclose a receiving cavity with the sewage holding part 31.

[0066] It can be understood that the cleaning base station 10 of the present disclosure is a cleaning base station that only discharges sewage by gravity; among the existing cleaning base stations, there are cleaning base stations provided with a sewage suction motor. When the dirt in the recycling bucket needs to be discharged in such cleaning base stations, the sewage suction motor is turned on to suck the dirt in the recycling bucket into the base station through negative pressure. In such cleaning base stations, the sewage discharge groove only needs to be set as a receiving box, which is different from the structural principle of the cleaning base station that discharges sewage by gravity.

[0067] During the working process of the cleaning base station 10 of the present disclosure, the cleaning device 90 is placed on the tray 2. The sewage discharge port 93 of the cleaning device 90 is located above the sewage receiving part 32, and the dirt discharged by the cleaning device 90 can be discharged into the sewage discharge groove 3. Among them, the sewage receiving part 32 is located in front of the sewage holding part 31 and is connected to the side wall of the sewage holding part 31, mainly used to receive the dirt discharged by the cleaning device 90 and guide the dirt discharged by the cleaning device 90 into the sewage holding part 31; the sewage holding part 31 is arranged in the base 1, mainly used to temporarily store the dirt and guide the dirt discharged by the cleaning device 90 into the sewage discharge pipe 6, so that the dirt is discharged to the outside.

[0068] Since the dirt - receiving part 32 is located on the front side of the dirt - containing part 31, and is connected to the side wall of the dirt - containing part 31, protruding forward from the base 1, the dirt - receiving part 32 that docks with the cleaning device 90 is located outside the cavity of the base 1 (the base 1 has a front wall surface 11 and a rear wall surface 12, the front wall surface 11 and the rear wall surface 12 are spaced apart in the second direction, the front wall surface 11, the rear wall surface 12 and the side wall connecting the front wall surface 11 and the rear wall surface 12 enclose the cavity of the base 1, and the dirt - receiving part 32 is located outside the front wall surface 11 of the base 1), and the dirt - containing part 31 is located inside the cavity of the base 1 (the dirt - containing part 31 is located inside the front wall surface 11 of the base 1). The dirt - receiving part 32 basically does not occupy the internal cavity volume of the base 1. On the one hand, it can reduce the thickness of the base 1, and on the other hand, it gives up the volume of the dirt - containing part 31 in the cavity of the base 1, effectively optimizing the layout of the cleaning base station 10 of the present disclosure, saving space, and being conducive to the miniaturization of the cleaning base station 10. Moreover, when the sewage discharge groove 3 is blocked, the dirt - receiving part 32 and the dirt - containing part 31 can jointly hold the dirt, preventing the dirt from overflowing from the sewage discharge groove 3. Compared with the existing cleaning base stations, the overall volume of the sewage discharge groove 3 of the cleaning base station 10 of the present disclosure is larger and the occupied space is smaller, effectively improving the user experience.

[0069] As Figure 6 shown, in an embodiment of the present disclosure, a roller brush groove 21 is provided on the tray 2. Taking the axial direction of the roller brush groove 21 (i.e., the length extension direction of the roller brush groove 21) as the first direction, and the direction perpendicular to the first direction as the second direction, both the first direction and the second direction are in the horizontal plane. The dirt - containing part 31 is configured to have a dimension in the first direction greater than its dimension in the second direction. Since the tray of the cleaning base station needs to receive the roller brush of the floor - brushing component of the cleaning device, the length of the cleaning base station in the first direction of the roller brush groove 21 needs to be at least greater than or equal to the length of the roller brush groove 21 in the first direction. Since the dimension of the dirt - containing part 31 in the first direction is greater than its dimension in the second direction, this design of the dirt - containing part 31 can make full use of the space in the axial direction of the roller brush groove of the base station. On the premise of ensuring the volume of the dirt - containing part 31 of the present disclosure, it can effectively reduce the thickness of the dirt - containing part 31 and the base 1 where it is located, which is conducive to the miniaturization of the base station, increasing the acceptance and favorability of users, and thus facilitating the layout of the cleaning base station 10 of the present disclosure.

[0070] As Figure 3 shown, in an embodiment of the present disclosure, the dirt - receiving part 32 is lower than the dirt - containing part 31, which can facilitate the cleaning of various parts in the sewage discharge groove 3 and prevent cleaning dead - ends from appearing in the sewage discharge groove 3.

[0071] It can be understood that in the sewage discharge groove 3 of the present disclosure, the dirt - receiving part 32 and the dirt - containing part 31 can be integrally formed, and are only distinguished as two parts with different functions, or the dirt - receiving part 32 and the dirt - containing part 31 can be separately processed and then fixedly connected together. The specific processing technology is not limited herein.

[0072] To control the operation of the cleaning base station 10 of the present disclosure, the cleaning base station 10 of the present disclosure may further include a control unit, which can be signal-connected to various components on the cleaning base station 10 of the present disclosure to control their working states.

[0073] Specifically, as Figures 7 to 10 shown, in an embodiment of the present disclosure, the top of the dirt receiving part 32 is configured to form a dirt receiving port 321 extending forward from the dirt containing part 31; the opening direction of the dirt receiving port 321 is configured to face upward and is configured to be docked with the sewage discharge port 93 of the cleaning device 90. Since the top of the dirt receiving part 32 extends forward from the dirt containing part 31 to form the dirt receiving port 321 with an upward opening, during the operation of the cleaning base station 10 of the present disclosure, when the cleaning device 90 is placed on the tray 2, it is convenient for the sewage discharge port 93 of the cleaning device 90 to be located above the dirt receiving part 32 and docked with the dirt receiving port 321; the dirt discharged by the cleaning device 90 can flow through the dirt receiving port 321 into the dirt receiving part 32 and then into the dirt containing part 31. As Figure 9 and Figure 10 shown, in an embodiment of the present disclosure, the end face where the dirt receiving port 321 is located is configured to extend obliquely downward from the position connected to the dirt containing part 31, so that the end face where the dirt receiving port 321 is located is configured to be lower than the position where the dirt receiving port 321 is connected to the dirt containing part 31 in the height direction. In this way, when the front side of the dirt receiving port 321 is inclined downward, when the user places the cleaning device 90 on the tray 2, it is convenient for the user to adjust the sewage discharge port 93 of the cleaning device 90 to be located obliquely above the dirt receiving port 321, so as to reduce interference and obstruction during docking, which is beneficial to docking the sewage discharge port 93 of the cleaning device 90 with the dirt receiving port 321, and the dirt discharged by the cleaning device 90 can flow through the dirt receiving port 321 into the dirt receiving part 32.

[0074] In another embodiment of the present disclosure, the end face where the dirt receiving port 321 is located is configured to extend on a horizontal plane from the position connected to the dirt containing part 31, so that the end face where the dirt receiving port 321 is located is configured to be flush with the position where the dirt receiving port 321 is connected to the dirt containing part 31 in the height direction. In this way, when the dirt receiving port 321 extends in the horizontal direction, after the user places the cleaning device 90 on the tray 2, the dirt receiving part 32 can effectively support the cleaning device 90 of the present disclosure, which can effectively prevent the cleaning device 90 from slipping from above the dirt receiving part 32, ensure that during the process of the cleaning device 90 discharging dirt, the sewage discharge port 93 of the cleaning device 90 is always docked with the dirt receiving port 321, and prevent the dirt discharged by the cleaning device 90 from flowing outside the cleaning base station 10 to cause pollution.

[0075] Furthermore, as Figure 10As shown, in an embodiment of the present disclosure, the plane where the sewage receiving port 321 is located is denoted as plane S, and the area of the sewage receiving part 31 on plane S is configured to be smaller than the area of the sewage receiving port 321 on plane S. Since the area of the sewage receiving part 31 on plane S is smaller than the area of the sewage receiving port 321 on plane S, it can ensure that the area of the sewage receiving port 321 can meet the requirements, so as to maximize the area of the sewage discharge port 93 of the cleaning device 90, thereby improving the sewage discharge speed of the cleaning device 90; moreover, it can also reduce the area of the sewage receiving part 31 on plane S, thereby reducing the overall area of the sewage discharge groove 3, thereby saving the space occupied by the sewage discharge groove 3 and greatly reducing the overall volume of the base 1.

[0076] Furthermore, as Figure 10 shown, in an embodiment of the present disclosure, the sewage receiving part 32 is configured as a tapered structure with a decreasing cross-sectional area from top to bottom. Since the sewage receiving part 32 is mainly used to receive the dirt discharged by the cleaning device 90, when the sewage receiving part 32 is a tapered structure with a decreasing cross-sectional area from top to bottom, it can facilitate the sewage receiving part 32 to guide the dirt discharged by the cleaning device 90 into the sewage receiving part 31 after receiving the dirt from the cleaning device 90, and effectively save the space occupied by the sewage receiving part 32.

[0077] Specifically, in one embodiment of the present disclosure, the contamination-receiving portion 32 includes an enclosing wall 322 on one side away from the contamination-receiving portion 31. The enclosing wall 322 is configured to extend obliquely downward from the top of the contamination-receiving portion 32 to dock with a corresponding position of the contamination-receiving portion 31. The distance from the top to the bottom of the enclosing wall 322 to the contamination-receiving portion 31 gradually decreases. The contamination-receiving portion 32 also includes a first side wall 323 and a second side wall 324 located on both sides of the enclosing wall 322. The first side wall 323, the second side wall 324, and the enclosing wall 322 are configured to enclose the contamination-receiving portion 32 on the contamination-receiving portion 31. The side of the contamination-receiving portion 32 opposite to the enclosing wall 322 can be open for communication with the inner cavity of the contamination-receiving portion 31. The contamination-receiving portion 32 and the contamination-receiving portion 31 enclose a receiving cavity. The dirt receiving portion 31 extends forward to form a dirt receiving port 321 of the dirt receiving portion 32. The dirt receiving portion 32 and the dirt receiving portion 31 are directly connected, facilitating modularization of the dirt receiving portion 32 and the dirt receiving portion 31. This structural continuity enhances the continuity of waste discharge, facilitating gravity-driven waste discharge. Furthermore, the dirt receiving portion 32 is primarily located outside the interior of the base 1, docking with the drain port of the cleaning device 90. The dirt receiving portion 32 substantially does not occupy the interior volume of the base 1. When blockage occurs, when dirt accumulates from bottom to top, the cavity enclosed by the dirt-receiving part 32 and the dirt-containing part 31 jointly contains the dirt, that is, when the dirt rises to a lower height, the capacity of the dirt-receiving part 32 and the dirt-containing part 31 is simultaneously utilized to contain the dirt; at the same time, since the dirt-receiving part 32 is formed by the dirt-containing part 31 extending on both sides, the two sides of the dirt-receiving part 32 need to be connected with the two sides of the dirt-containing part 31, and the shape of the dirt-containing part 31 makes the cross-sectional area of the connection between the two larger, that is, the distance between the first side wall 323 and the second side wall 324 becomes larger, as a result, the volume of the containing cavity enclosed by the dirt-receiving part 31 and the dirt-receiving part 32 is larger. Compared with the prior art that only uses the dirt-containing part to contain dirt, while ensuring the same dirt capacity, the volume of the sewage trough is greatly reduced, which is conducive to the miniaturization of the base station and increases user acceptance and favorability.

[0078] Because the enclosing wall 322 is located on a side away from the dirt receiving portion 31, and the top of the dirt receiving portion 32 extends downwardly at an angle to connect with the corresponding position of the dirt receiving portion 31, the dirt receiving portion 32 mainly receives dirt from the cleaning equipment 90 through the enclosing wall 322, and the enclosing wall 322 can guide the dirt discharged by the cleaning equipment 90 to flow along the enclosing wall 322 to the dirt receiving portion 31. The first side wall 323 and the second side wall 324 are mainly used to prevent dirt from flowing along the enclosing wall 322 and flowing out of the sewage chute 3.

[0079] Of course, it can be understood that when the first side wall 323 and the second side wall 324 are configured such that the bottom slopes towards the side closer to each other, and the enclosing wall 322, the first side wall 323, and the second side wall 324 as a whole form a square funnel shape, the first side wall 323 and the second side wall 324 can also receive the dirt from the cleaning device 90 and guide the dirt discharged by the cleaning device 90 to flow along the first side wall 323 and the second side wall 324 to the dirt storage part 31. The enclosing wall 322, the first side wall 323, and the second side wall 324 can be integrally formed, or the individual parts can be fixed together after being formed separately. The specific processing technology is not limited herein.

[0080] As Figure 5 shown, in an embodiment of the present disclosure, the side of the dirt receiving part 32 opposite to the enclosing wall 322 is open, for communicating with the inner cavity of the dirt storage part 31, and the projection of the dirt receiving part 32 towards the dirt storage part 31 does not exceed the maximum diameter of the dirt storage part 31. Since the side of the dirt receiving part 32 opposite to the enclosing wall 322 is open for communicating with the inner cavity of the dirt storage part 31, it is convenient for the dirt to flow from the dirt receiving part 32 into the dirt storage part 31. And since the projection of the dirt receiving part 32 towards the dirt storage part 31 does not exceed the maximum diameter of the dirt storage part 31, the overall projection of the dirt receiving part 32 can fall within the area of the dirt storage part 31, and there will be no left - right relative misalignment between the dirt receiving part 32 and the dirt storage part 31, which is beneficial to reducing the size of the base 1 in the axial direction of the roller brush groove 21.

[0081] As described above, the sewage discharge groove 3 includes a dirt storage part 31 located in the base 1 and a dirt receiving part 32 communicating with the inner cavity of the dirt storage part 31; the dirt receiving part 32 is configured to have a dirt receiving port 321 for receiving the sewage discharge port 93 of the cleaning device 90.

[0082] As Figures 7 to 10 shown, in an embodiment of the present disclosure, the dirt receiving part 32 has a sewage discharge surface 325, and at least part of the dirt flowing in from the dirt receiving port 321 is configured to be guided from the sewage discharge surface 325 to the inner cavity of the dirt storage part 31; the area on the sewage discharge surface 325 corresponding to the sewage discharge port 93 is configured to be a flat surface or a continuously smooth curved surface.

[0083] During the working process of the cleaning base station 10 of the present disclosure, the cleaning device 90 is placed on the tray 2, the sewage discharge port 93 of the cleaning device 90 is located above the dirt receiving part 32, and the dirt discharged by the cleaning device 90 can be discharged into the sewage discharge groove 3. Among them, the sewage discharge surface 325 of the dirt receiving part 32 can receive the dirt discharged from the sewage discharge port 93 of the cleaning device 90 and guide the dirt discharged by the cleaning device 90 to the inner cavity of the dirt storage part 31, that is, at least part of the dirt flowing out from the sewage discharge port 93 can flow from the sewage discharge surface 325 to the inner cavity of the dirt storage part 31; the dirt storage part 31 is arranged in the base 1, mainly used for temporarily storing the dirt and guiding the dirt discharged by the cleaning device 90 to the sewage discharge pipe 6 so that the dirt is discharged to the outside.

[0084] Specifically, since the area on the sewage discharge surface 325 corresponding to the sewage discharge port 93 is constructed as a flat surface or a continuous smooth curved surface, when the dirt falls from the dirt receiving port 321 onto the sewage discharge surface 325, it will flow smoothly downward, ensuring that the dirt continues to flow toward the sewage pipe 6 with greater kinetic energy. It can also prevent the dirt from splashing out of the dirt receiving port 321 when it falls onto the sewage discharge surface 325 and onto the base 1 or the tray 2 of the cleaning base station 10, eliminating the need for the user to perform secondary cleaning on the cleaning base station 10, effectively reducing the user's burden and improving the user experience.

[0085] As Figure 9 and Figure 10 shown, in an embodiment of the present disclosure, the dirt receiving part 32 is constructed to be located on the front side of the dirt containing part 31, and the top of the dirt receiving part 32 is constructed to extend from the dirt containing part 31 in the direction of the tray 2 to form the dirt receiving port 321. Since the dirt receiving part 32 is located on the front side of the dirt containing part 31 and the top of the dirt receiving part 32 extends from the dirt containing part 31 in the direction of the tray 2 to form the dirt receiving port 321, it is convenient for the sewage discharge port 93 of the cleaning device 90 to be located above the dirt receiving part 32 and dock with the dirt receiving port 321; the dirt discharged by the cleaning device 90 can pass through the dirt receiving port 321 and flow into the dirt receiving part 32, and then flow into the dirt containing part 31. Since the dirt receiving part 32 is located on the front side of the dirt containing part 31 and is connected to the side wall of the dirt containing part 31, protruding forward from the base 1, the dirt receiving part 32 is located outside the front wall surface 11 of the base 1, that is, the sewage discharge surface 325 is located outside the front wall surface 11 of the base 1, without occupying the cavity volume of the base 1.

[0086] As Figure 4 shown, in an embodiment of the present disclosure, in the front-rear direction of the base 1, one end of the sewage discharge surface 325 adjacent to the tray 2 is denoted as end A, and the end far from the tray 2 is denoted as end B; the connection line between end A and end B is constructed to form an angle less than or equal to 40° with the central axis of the sewage discharge port 93. Since the angle between the connection line between one end A of the sewage discharge surface 325 adjacent to the tray 2 and the end B far from the tray 2 and the central axis of the sewage discharge port 93 is less than or equal to 40°, it can further ensure that when the dirt falls from the sewage discharge port 93 of the cleaning device 90 onto the sewage discharge surface 325, it will not have a large impact on the sewage discharge surface 325, prevent the dirt from splashing out of the dirt receiving port 321 when it falls onto the sewage discharge surface 325 and onto the base 1 or the tray 2 of the cleaning base station 10, and can flow smoothly downward under the action of gravity, ensuring that the dirt continues to flow toward the sewage pipe 6 with greater kinetic energy, thereby improving the sewage discharge efficiency of the cleaning base station 10 of the present disclosure. As Figure 4As shown, more precisely, since the sewage discharge surface 325 is used to receive the dirt falling from the sewage discharge port 90 of the cleaning device 90, the area where the sewage discharge port 90 projects onto the sewage discharge surface 325 along the extension direction of the body of the cleaning device 90 is denoted as W. Since the sewage discharge surface 325 may be slightly curved, based on the tangent direction of the center point of W, the angle between the tangent direction of the center point of W and the vertical direction does not exceed 40°.

[0087] Further, as Figure 4 shown, in an embodiment of the present disclosure, in the front-back direction of the base 1, the end of the sewage discharge port 93 away from the base 1 is denoted as end C, and the end adjacent to the base 1 is denoted as end D; the portion between end C and end D along the orthographic projection of the central axis of the sewage discharge port 93 is configured to be located between end A and end B. Since the orthographic projection of the portion between the front end C of the sewage discharge port 93 away from the base 1 and the rear end D adjacent to the base 1 on the central axis of the sewage discharge port 93 is located between the above-mentioned end A and end B, it can be ensured that after the dirt falls from the sewage discharge port 93 of the cleaning device 90, it can fall into the area where the sewage discharge surface 325 is located, rather than directly falling into other positions such as the inner cavity of the dirt receiving part 31, thereby avoiding splashing when the dirt directly falls into the inner cavity of the dirt receiving part 31 and effectively exerting the guiding function of the sewage discharge surface 325.

[0088] Further, in an embodiment of the present disclosure, the orthographic projection of the sewage discharge port 93 on its central axis is within the orthographic projection range of the sewage discharge surface 325 on the central axis of the sewage discharge port 93. In this way, it can be further ensured that after the dirt falls from the sewage discharge port 93 of the cleaning device 90, it can fall onto the sewage discharge surface 325 and flow obliquely downward along the sewage discharge surface 325, rather than directly falling into other positions such as the inner cavity of the dirt receiving part 31 and being unable to continue flowing towards the sewage pipeline 6 using kinetic energy.

[0089] As Figure 4 shown, in an embodiment of the present disclosure, the orthographic projection of the end D of the sewage discharge port 93 along the central axis of the sewage discharge port 93 coincides with the bottom end of the dirt receiving part 32. In this way, it can not only ensure that the sewage discharge port 03 can be projected onto the sewage discharge surface 325 and effectively utilize the sewage discharge surface 325 to guide the flow of dirt, but also does not need to set a too long sewage discharge surface 325, effectively ensuring the miniaturization of the cleaning base station 10 of the present disclosure.

[0090] As Figure 7As shown, in an embodiment of the present disclosure, the dirt receiving portion 32 includes an enclosing wall 322 on a side away from the dirt containing portion 31, and the inner wall of the enclosing wall 322 is configured as a sewage discharge surface 325; the enclosing wall 322 is configured to extend obliquely downward from the top of the dirt receiving portion 32 to be docked with a corresponding position of the dirt containing portion 31; the dirt receiving portion 32 further includes a first side wall 323 and a second side wall 324 located on both sides of the enclosing wall 322, and the first side wall 323, the second side wall 324, and the enclosing wall 322 are configured to enclose the dirt receiving portion 32 on the dirt containing portion 31. Since the inner wall of the enclosing wall 322 can serve as the sewage discharge surface 325, there is no need to separately provide a sewage discharge surface 325 inside the dirt receiving portion 32, thereby effectively saving the materials required for processing the dirt receiving portion 32.

[0091] Further, in an embodiment of the present disclosure, the orthographic projection of the sewage outlet 93 on its central axis is configured to be located between the first side wall 323 and the second side wall 324. That is, the orthographic projection of the sewage outlet 93 on its central axis can be entirely located on the enclosing wall 322. In this way, it can be further ensured that after the dirt falls from the sewage outlet 93 of the cleaning device 90, it can all fall on the enclosing wall 322 and flow obliquely downward along the enclosing wall 322, rather than directly falling into other positions such as the inner cavity of the dirt containing portion 31, avoiding splashing when the dirt directly falls into the inner cavity of the dirt containing portion 31 and also preventing the dirt from continuing to flow towards the sewage pipe 6 by using kinetic energy.

[0092] As Figure 10 shown, in an embodiment of the present disclosure, the outlet of the sewage trough 3 is provided with an end E at the front side and an end F at the rear side, and the extension line of points A and B is located between the end E and the end F of the sewage trough 3. In this way, the dirt discharged from the sewage outlet 93 can directly fall onto the outlet of the sewage trough 3 after passing through the sewage discharge surface 325 of the dirt receiving portion 32, minimizing the blockage on the sewage discharge path, and the dirt discharged later can also have a gravity impact on the dirt discharged earlier, which is more conducive to the discharge of the dirt.

[0093] Further, as Figure 10 shown, in an embodiment of the present disclosure, for the center point G of the outlet of the sewage trough 3, the extension line of points A and B is located between the end E and the center point G, that is, the end B is located above the connection line of AE. In this way, the dirt discharged from the sewage outlet 93 can directly fall onto the outlet of the sewage trough 3 after passing through the sewage discharge surface 325 of the dirt receiving portion 32, minimizing the blockage on the sewage discharge path. It can be understood that the extension line of points A and B being located between the end E and the center point G includes the case of passing through the end E or the center point G.

[0094] Similarly, as Figure 10As shown, in an embodiment of the present disclosure, the intersection point H of the DF two lines and the dirt receiving part 32 or the dirt containing part 31 is located below the I point, that is, there is no obstruction on the DF connection line. In this way, it can be further ensured that the dirt discharged from the sewage outlet 93 can directly fall to the sewage tank outlet after passing through the sewage discharging surface 325 of the dirt receiving part 32, and the obstruction is minimized on the sewage discharging path.

[0095] As Figure 4 shown, in an embodiment of the present disclosure, the inclination angle of the sewage discharging surface 325 relative to the horizontal plane is configured to continuously decrease from top to bottom. It can be understood that the inclination angle of any point on the sewage discharging surface 325 relative to the horizontal plane is the included angle formed between the tangent line passing through this point and the horizontal plane, and the maximum of this included angle is a right angle, Figure 4 and the inclination angle of the sewage discharging surface 325 in

[0096] Specifically, as Figure 4 shown, in an embodiment of the present disclosure, the area of the sewage outlet 93 is configured to be smaller than the area of the dirt receiving port 321; when the cleaning device 90 is placed in the cleaning base station 10, the orthographic projection of the sewage outlet 93 on its central axis is located within the dirt receiving port 321. In this way, it can be ensured that when the cleaning device 90 is placed in the cleaning base station 10, the dirt discharged from the sewage outlet 93 of the cleaning device 90 can all fall into the dirt receiving port 321 and will not flow outside the dirt receiving port 321, causing pollution to the cleaning base station 10. Moreover, after the dirt falls into the dirt receiving part 32, even if sputtering occurs, it is not easy to sputter outside the dirt receiving port 321, preventing the dirt from splashing out of the dirt receiving port 321.

[0097] As Figure 18 shown, in an embodiment of the present disclosure, a filtering component 326 is arranged in the inner cavity of the dirt receiving part 32. The filtering component 326 is arranged within the dirt receiving port 321 and is configured to be detachable from the dirt receiving port 321. The filtering component 326 is configured to extend downward to form a filtering cavity; when the cleaning device 90 is placed in the cleaning base station 10, the orthographic projection of the sewage outlet 93 on its central axis is located within the filtering cavity.

[0098] By arranging a filtering component 326 in the inner cavity of the dirt receiving part 32, during the operation of the cleaning base station 10 of the present disclosure, all the dirt discharged by the cleaning device 90 will pass through the filtering component 326. After the solid dirt with a larger size is filtered in the filtering cavity, the remaining dirt will fall on the dirt discharging surface 325 and be discharged into the dirt discharging groove 3. Since when the cleaning device 90 is placed in the cleaning base station 10, the orthographic projection of the dirt discharging port 93 on its central axis is located in the filtering cavity, it can be ensured that all the dirt discharged by the cleaning device 90 can be filtered by the filtering component 326, and the situation where some dirt flows directly into the dirt discharging groove 3 without being filtered by the filtering component 326 will not occur.

[0099] As Figure 10 shown, in an embodiment of the present disclosure, the inclination angle of the dirt discharging surface 325 relative to the horizontal plane is configured to be less than the inclination angle of the side wall of the dirt receiving part 31 at the position below the enclosing wall 322. Since the inclination angle of the dirt discharging surface 325 relative to the horizontal plane is less than the inclination angle of the side wall of the dirt receiving part 31 at the position below the enclosing wall 322, the side wall of the dirt receiving part 31 at the position below the enclosing wall 322 will deviate downward from the path along which the dirt discharging surface 325 extends downward. When the sewage discharged by the cleaning device 90 flows downward along the dirt discharging surface 325 to the dirt receiving part 31, most of it will no longer flow downward along the side wall of the dirt receiving part 31, but will rush into the middle part of the inner cavity of the dirt receiving part 31, so as to avoid the generation of vortices or splashes when the dirt flows to the dirt receiving part 31 as much as possible, reduce the impact between the dirt, ensure the smooth flow of the dirty sewage flow, and thus effectively improve the discharging speed of the dirt from the bottom of the dirt receiving part 31.

[0100] As Figure 17 shown, in an embodiment of the present disclosure, at least one guiding rib 327 is arranged on the dirt discharging surface 325, and the guiding rib 327 is configured to extend along the dirt flowing direction on the dirt discharging surface 325. The extending direction of the guiding rib 327 can be parallel to the dirt flowing direction or can be arranged at an angle with the dirt flowing direction. In this way, after the dirt discharged by the cleaning device 90 falls on the dirt discharging surface 325, it can flow along the extending direction of the guiding rib 327, reduce the splashing of the dirt on the dirt discharging surface 325, and the dirt will not impact on the first side wall 323 and the second side wall 324, so as to effectively reduce the kinetic energy loss of the dirt and ensure that the dirt flows obliquely downward along the dirt discharging surface 325 as soon as possible.

[0101] As Figure 3 and Figure 4As shown, in an embodiment of the present disclosure, in the cleaning system of the present disclosure, the cleaning device 90 is provided with a sewage discharge port 93, and a lower cover 95 is provided at the sewage discharge port 93. The lower cover 95 has a first position for closing the sewage discharge port 93 and a second position for opening the sewage discharge port 93; the cleaning device 90 is docked with the cleaning base station 10, and the lower cover 95 can be rotated from the first position to the second position to open the sewage discharge port 93; when the lower cover 95 is in the second position, the lower cover 95 extends into the sewage receiving port 321 of the sewage receiving part 32 and is located on one side of the sewage discharge surface 325, and the opening angle range of the lower cover 95 is 90°-100°.

[0102] In this way, during the operation of the cleaning device 90 of the present disclosure, the lower cover 95 can be rotated from the first position to the second position to open the sewage discharge port 93; since when the lower cover 95 is in the second position, the lower cover 95 extends into the sewage receiving port 321 of the sewage receiving part 32 and is located on one side of the sewage discharge surface 325, and the opening angle range of the lower cover 95 is 90°-100°, the dirt inside the cleaning device 90 can flow along the lower cover 95, and the lower cover 95 will not hinder the flow of the dirt, ensuring the normal flow of the dirt in the sewage bucket 92.

[0103] As Figure 18 shown, in an embodiment of the present disclosure, the sewage receiving part 32 is located on the base 1. The base 1 is provided with a mounting port 4 adapted to the sewage receiving port 321 on one side of the tray 2, and the end faces on both sides of the mounting port 4 are configured to be higher than the end face of the sewage receiving port 321. When the user places the cleaning device 90 on the tray 2, a part of the cleaning device 90 enters the mounting port 4, and the sewage discharge port 93 is located above the sewage receiving port 321. Since the end faces on both sides of the mounting port 4 are higher than the end face of the sewage receiving port 321, it can effectively prevent the dirt from splashing out from both sides where the mounting port 4 is located when the cleaning device 90 discharges sewage, thereby avoiding polluting the outside world and improving the user experience.

[0104] Specifically, as Figure 4As shown, the lower cover 95 of the cleaning device 90 that seals the sewage outlet 93 is rotatably connected to the sewage bucket 92 at the C end through a rotating shaft. When the cleaning device 90 needs to discharge sewage, after the lower cover 95 is unlocked from the sewage bucket 92 at the D end, the lower cover 95 rotates around the rotating shaft at the C end to open, so as to open the sewage outlet 93. Therefore, during the sewage discharge process of the cleaning device 90, the lower cover 95 of the sewage bucket 92 can effectively prevent dirt from splashing out from the front side, that is, the side of the sewage receiving port 321 away from the base 1. Moreover, the rotation opening angle of the lower cover 95 of the sewage bucket 92 is greater than or equal to 90°, so that when the dirt is discharged from the sewage outlet 93, the lower cover 95 will not block the sewage on the sewage discharge path. At the same time, since the lower cover 95 extends into the sewage receiving port 321 and abuts against the sewage discharge surface 325 after rotating and opening, if the rotation opening angle of the lower cover 95 is too large, the space required at the sewage discharge surface 325 will also become larger accordingly, and the size of the entire sewage receiving part 32 exceeding the outside of the base 1 will become larger. And the cleaning device 90 needs to be placed and taken on and off the cleaning base station 10. If the size of the sewage receiving part 32 protruding outside the base 1 is too large, the floor brush assembly or the rear side of the machine body of the cleaning device 90 will interfere with the sewage receiving part 32 during the placement and taking of the cleaning device 90, resulting in the need to redesign the cleaning base station 10. Therefore, considering both sewage discharge and the placement and taking of the cleaning device 90, the rotation opening angle of the lower cover 95 of the sewage tank 92 is not greater than 100°, and it abuts against the sewage discharge surface 325 in the open state to ensure the docking and convenient taking of the cleaning device while not affecting sewage discharge.

[0105] Furthermore, when the cleaning device 90 is in an upright state, its upright body is generally at an acute angle with the floor brush assembly, the upright body is in a forward-tilted state, and generally heavy components such as a blower unit and a battery are carried on the upright body. In order to support the cleaning device 90 and prevent the cleaning device 90 from tipping forward on the base station, as Figure 18 shown, in an embodiment of the present disclosure, the end faces on both sides of the installation opening 4 are configured to extend forward to form convex ribs 41, and the convex ribs 41 are configured to engage with the bottom of the body 91 of the cleaning device 90 or the sewage bucket 92. That is, grooves can be provided at the bottom of the body 91 or the sewage bucket 92. Specifically, at least two symmetric grooves are provided at the bottom of the body 91 or the sewage bucket 92. When the user places the cleaning device 90 on the cleaning base station 10, the floor brush assembly 94 is carried on the tray 2, and the convex ribs 41 on the front side of the installation opening 4 can be engaged in the grooves at the bottom of the body 91 of the cleaning device 90 or the grooves at the bottom of the sewage bucket 92, so as to effectively prevent the cleaning device 90 from slipping off or relatively deflecting from the installation opening 4 and ensure the normal progress of the sewage discharge process. As Figure 18 shown, the convex ribs 41 on both sides of the installation opening 4 are not connected together, but a notch is formed in the middle area, so as to be used to avoid the sewage outlet 93 of the body 91 or the sewage bucket 92 and facilitate the user to place the cleaning device 90 into the installation opening 4.

[0106] AsFigure 9 As shown, in one embodiment of the present disclosure, the dirt receiving portion 31 is configured to have at least a reduced-diameter portion with an increasing size from top to bottom. The dirt holding portion 32 is configured to be at least connected to the reduced-diameter portion and is configured to be transitionally connected to the side wall of the reduced-diameter portion. The dirt drained from the dirt holding portion 32 mainly flows to the middle and lower parts of the dirt receiving portion 31 and is then drained away through the sewage discharge pipe 6. The middle and lower parts of the dirt receiving portion 31 are the effective parts for temporarily storing dirt. Designing the dirt receiving portion 31 to have at least a reduced-diameter portion with an increasing size from top to bottom can effectively expand the volume of the inner cavity of the dirt receiving portion 31 that mainly plays the role of temporarily storing dirt, so as to temporarily store the dirt discharged from the cleaning device 90. Even if a blockage occurs, the dirt mainly accumulates in the middle and lower parts of the dirt receiving portion 31, avoiding the distance between the dirty water surface and the dirt receiving opening 321 from being too close. At the same time, it can also effectively reduce the volume of the upper part of the dirt receiving portion 31 that has a relatively small effect on storing dirt. In this way, the structure of the dirt receiving portion 31 is reasonably designed to maximize the reduction of the occupied space of the dirt receiving portion 31 while ensuring sufficient capacity. And as described above, the dirt holding portion 32 is a tapered structure with a decreasing volume from top to bottom, which can ensure that the overall width of the sewage discharge groove 3 of the present disclosure will not increase significantly. Moreover, since the dirt holding portion 32 is at least connected to the reduced-diameter portion and is transitionally connected to the side wall of the reduced-diameter portion, that is, the connection position of the dirt holding portion 32 and the reduced-diameter portion is located on the extension path of the reduced-diameter portion itself, the dirt holding portion 32 does not extend into the inner cavity of the dirt receiving portion 31, and the dirt holding portion 32 will not form an obstructive portion in the inner cavity of the dirt receiving portion 31, so it will not hinder the sewage from falling. Moreover, there will be no cleaning dead angle at the connection position of the dirt holding portion 32 and the dirt receiving portion 31, which is convenient for cleaning the sewage discharge groove 3 and ensures that the sewage discharge groove 3 can be cleaned cleanly.

[0107] Specifically, as Figure 9As shown, in an embodiment of the present disclosure, the dirt - holding part 31 includes a first part 311 located above and a second part 312 located below. The first part 311 is configured to be docked with the second part 312. The size of the first part 311 is configured to be a gradually expanding structure with an increasing cross - sectional area from top to bottom. The dirt - receiving part 32 is configured to be transitionally connected with the first part 311, and the size of the second part 312 is configured to be a gradually shrinking structure with a decreasing cross - sectional area from top to bottom. Among them, the first part 311 of the dirt - holding part 31 has a gradually expanding structure with an increasing cross - sectional area from top to bottom, which can facilitate the formation of a reduced - diameter part with an increasing size from top to bottom, so as to temporarily store dirt during the process of the cleaning device 90 discharging dirt. Moreover, the cross - sectional area of the dirt - holding part 31 gradually increases from top to bottom, and the dirt - receiving part 32 is docked on both sides of the first part 311, so that the lower receiving area is further enlarged, which is beneficial to expanding the clogging capacity. And the second part 312 has a gradually decreasing cross - sectional area from top to bottom until it is docked with the sewage discharge pipe 6, so as to facilitate the dirt - holding part 31 to divert the dirt discharged by the cleaning device 90 into the sewage discharge pipe 6. After the cleaning device 90 finishes discharging dirt, it is ensured that all the dirt can be discharged into the sewage discharge pipe 6, avoiding dirt residue in the dirt - holding part 31. In addition, the first part 311 has a gradually increasing cross - sectional area from top to bottom, and the second part 312 has a gradually decreasing cross - sectional area from top to bottom, which is beneficial for the flushing water flowing out from the top of the sewage discharge tank to flow down along the inner wall of the sewage discharge tank to flush the sewage discharge tank. Further, the first part 311 has a continuous and smooth gradually expanding structure with an increasing cross - sectional area from top to bottom, and the second part 312 has a continuous and smooth gradually shrinking structure with a decreasing cross - sectional area from top to bottom. First of all, the continuous and smooth structure is beneficial to the flow of flushing water. Secondly, under the condition of being beneficial to flushing, the continuous and smooth structure further ensures that the distance between the first side wall 323 and the second side wall 324 of the dirt - receiving part 32 docked on both sides of the first part 311 is maximized, that is, the area enclosed by the dirt - receiving part 32 is the largest, the volume enclosed by the dirt - receiving part 32 and the dirt - holding part 31 is the largest, improving the clogging capacity, and being beneficial to reducing the occupied volume of the sewage discharge tank. Specifically, as Figure 9 As shown, in an embodiment of the present disclosure, the dirt - receiving part 32 is formed on the first part 311 of the dirt - holding part 31, and includes an enclosing wall 322 on the side away from the dirt - holding part 31. The enclosing wall 322 is configured to extend obliquely downward from the top of the dirt - receiving part 32 to be transitionally connected with the bottom of the first part 311. In this way, during the process of the sewage discharged by the cleaning device 90 flowing downward along the enclosing wall 322, it can directly flow to the bottom of the first part 311, that is, the position where the first part 311 is docked with the second part 312, which is also the part with the largest inner diameter of the dirt - holding part 31. In this way, it can effectively reduce the impact and sputtering of dirt on the inner wall of the dirt - holding part 31, avoid the formation of vortices in the dirt - holding part 31, reduce the residence time of dirt in the dirt - holding part 31, and improve the sewage discharge efficiency of the sewage discharge tank 3 of the present disclosure.

[0108] Further, in an embodiment of the present disclosure, the inclination angle of the enclosing wall 322 relative to the horizontal plane is configured to be less than the inclination angle of the portion of the second part 312 located below the enclosing wall 322. That is, as Figure 10 shown, the side wall at the corresponding position of the second part 312 will deviate downward from the path of the downward extension of the enclosing wall 322. When the sewage discharged by the cleaning device 90 flows downward along the enclosing wall 322 to the second part 312, most of it will no longer flow downward along the side wall of the second part 312, but will rush into the middle of the inner cavity of the sewage receiving part 31, so as to avoid the generation of vortices or splashes when the dirt flows to the second part 312 as much as possible, reduce the impact between the dirt, ensure the smooth flow of the dirty sewage flow, and thus effectively improve the discharge speed of the dirt from the bottom of the sewage receiving part 31.

[0109] It can be understood that the inclination angle of the enclosing wall 322 relative to the horizontal plane being less than the inclination angle of the portion of the second part 312 located below the enclosing wall 322 means that the inclination angle of any point on the enclosing wall 322 relative to the horizontal plane is less than the inclination angle of any point on the portion of the second part 312 located below the enclosing wall 322.

[0110] As Figure 9 shown, in an embodiment of the present disclosure, the sewage receiving port 321 is configured to extend from the position connected to the first part 311 towards the tray 2 to exceed the second part 312. Since the sewage receiving port 321 extends from the position connected to the first part 311 towards the tray 2 to exceed the second part 312, it is convenient for the sewage receiving port 321 to be docked with the cleaning device 90, thereby increasing the area of the sewage receiving port 321 within a limited space and facilitating the docking of the sewage discharge port 93 of the cleaning device 90 with the sewage receiving port 321.

[0111] As Figure 9 shown, in an embodiment of the present disclosure, the dimension of the first part 311 in the height direction is greater than the dimension of the second part 312 in the height direction.

[0112] It can be understood that since the receiving dirt portion 32 is formed on the first part 311 of the dirt receiving portion 31, the receiving dirt portion 32 is used to guide the sewage in the sewage bucket of the cleaning device towards the sewage outlet, and the first part 311 temporarily stores dirt during the process of the cleaning device 90 discharging dirt. The main function of the second part 312 is to divert the dirt discharged by the cleaning device 90 into the sewage pipeline 6 and, at the same time, jointly store dirt with the receiving dirt portion 32 when the sewage discharge groove is blocked. When the dimension of the first part 311 in the height direction is greater than that of the second part 312 in the height direction, it is beneficial for the receiving dirt portion 32 to guide the dirt to the position closest to the bottom as much as possible. At the same time, it can also effectively ensure that the volume of the first part 311 can meet the requirements, preventing dirt from overflowing from the sewage discharge groove 3 when the cleaning device 90 discharges sewage too quickly or the sewage pipeline 6 is blocked. Moreover, it can form a relatively short and plump area as a whole for the second part 312, facilitating the rapid discharge of dirt from the dirt receiving portion 31 and reducing the overall height of the dirt receiving portion 31. At the same time, when flushing the sewage discharge groove, the height of the first part 311 is greater, so the slope of the arc surface of the first part 311 is greater, which is beneficial for the cleaning water flowing out from the top of the first part 311 to flow downward along the inner wall of the arc surface of the first part 311 for flushing. In addition, since there are also some horizontal sewage pipelines inside the base station in addition to the sewage discharge groove, and the sewage pipelines have a capacity, the dimension of the second part in the height direction can be appropriately reduced to lower the overall height without affecting the capacity below the detection position 81 described below.

[0113] As shown in the Figure 10 attachment, OJ is the vertical line passing through point B, OEF is the horizontal line passing through the upper surfaces of points E and F at the bottom outlet of the sewage discharge groove 3, AJ is the horizontal line passing through point A, ABK is the line passing through points A and B, point K is the intersection of the extension line of AB and the line OEF, h1 is the vertical height from point A to point B, and h2 is the height from point B to point E, that is, the vertical height of the second part 312.

[0114] When designing the sewage discharge tank, since the sewage receiving port of the sewage receiving part needs to be docked with the body of the cleaning device, point A is the point on the sewage receiving port 321 that is farthest from the front wall surface 11 of the base 1, which is determined. The plane where the bottom outlet of the sewage discharge tank 3 is located is also basically determined, approximately the plane where the upper surface of the tray is located (because the base is located in the lower space of the upper surface of the tray and needs to accommodate the sewage pipe 6) or the plane where the charging contacts are located (to set the contraction part 34). Therefore, the vertical height |OJ| from point A to point E is also determined, which is the vertical height from point A to the bottom outlet of the sewage discharge tank 3, denoted as S2, and h1 + h2 = |OJ| = S2. Point B is the intersection point where the sewage receiving part extending outside the base extends towards the base at a certain angle (i.e., the acute angle formed by the line AB and the vertical line OJ. For the convenience of calculation and explanation, this angle is approximated as the sewage discharge angle θ) at point A and intersects with the vertical outer surface of the base. That is, the vertical line OJ is determined, basically the front vertical surface of the base, and point B is basically a point on or near the front vertical surface of the base. According to different sewage discharge angles, point B can move up and down in the direction of the vertical line OJ. Therefore, the length |AJ| of AJ is also basically determined, which is the horizontal distance from point A to the front wall surface 11 of the base or its vicinity, denoted as S1, |AJ| = S1. According to Figure 10 , tanθ = |AJ| / h1 = |OK| / h2, that is, h1 / h2 = |AJ| / |OK|. As mentioned above, it is necessary to ensure that the sewage discharge angle θ is within 40°, then h1 ≥ |AJ| / tanθ, and this is the minimum value of h1, that is, the minimum value of h1 / h2. In addition, the extension line of AB optimally falls between points E and F. When |OK| = |OE|, h1 is the maximum value, and h1 / h2 is also the maximum value. At this time, h1 / h2 ≤ |AJ| / |OE|. Since the horizontal distance from point A to point F is generally not less than the vertical height from point A to point F, when the extension line of AB passes through point F, it does not meet the requirement that the sewage discharge angle is within 40°. Therefore, the minimum value of h1 is based on meeting the sewage discharge angle. That is, (|AJ| / tanθ) / (|OJ| - |AJ| / tanθ) ≤ h1 / h2 ≤ |AJ| / |OE|, and |OE| is the horizontal distance from the point (O) where the outlet of the sewage discharge tank 3 is close to the front wall surface 11 of the base 1 to the front wall surface 11 of the base 1 or its vicinity, denoted as S3. That is, (S1 / tanθ) / (S2 - S1 / tanθ) ≤ h1 / h2 ≤ S1 / S3.

[0115] In addition, in order to prevent dirt from accumulating in the sewage discharge tank 3 and not being drained in time when the cleaning device 90 discharges sewage, the length |EF| of the outlet of the sewage discharge tank 3 is set to be not less than the length of |AJ|. At the same time, for the miniaturization of the base station, the length |EF| of the outlet of the sewage discharge tank 3 does not need to be too large. Optimally, |EF| ≈ |AJ|.

[0116] In this example, according to the general dimensions of the cleaning device 90 in this field, |OJ| ≈ 2.3|AJ|.

[0117] In this example, since the sewage discharge angle needs to be ensured to be within 40° to prevent splashing when dirt falls, when the sewage discharge angle is exactly equal to 40°, point B is at the highest allowable position. At this time, h1 has the first condition: |AJ| / h1min = tan40°, h1min = 1.2|AJ|, then h2max = 1.1|AJ|, that is, h1 / h2 ≥ 1.1.

[0118] As described above, the extension line of AB optimally falls between points E and F, so that the dirt directly falls into the range of the bottom outlet EF of the sewage discharge trough 3 after being guided by the AB section. Under this condition, point B can be located between the intersection of the AE line and the OJ line and the intersection of the AF line and the OJ line. Theoretically, the outlet E point of the sewage discharge trough 3 can be infinitely close to the front surface of the base, but |EF| is determined. The outlet of the sewage discharge trough 3 needs to be connected to the pipe orifice of the sewage discharge pipe 6. Generally, the outlet of the sewage discharge trough 3 is located at the central position of the base, and various other components need to be accommodated in the base station. In this embodiment, the distance |OE| between point E and the OJ vertical line (front surface of the base) is approximately 0.5|AJ|. When the extension line of AB passes through point E, h1 / h2 = 2, and the sewage discharge angle is 33°; when the extension line of AB passes through point F, h1 / h2 = 0.7, and at this time the sewage discharge angle is 42°, which does not meet the requirement that the sewage discharge angle is less than 40°. Therefore, considering comprehensively, the best range of h1 / h2 is 1.1 - 2.

[0119] In addition, considering comprehensively the smoothness of sewage discharge, the flushing of the sewage discharge trough, and the maximization of the volume of the sewage discharge trough, point B is set as the place where the maximum transverse diameter of the dirt-containing part is located at the same time, that is, as the boundary between the first part 311 and the second part 312. The maximum transverse diameter of the dirt-containing part is directly related to the thickness of the base station. The greater the thickness of the base station, the larger the maximum transverse diameter of the dirt-containing part can be correspondingly. It can be imagined that in order to ensure the smoothness of sewage discharge and the flushing of the sewage discharge trough, there should be only one smooth arc surface from point B to the outlet E point of the sewage discharge trough. On this basis, if the maximum transverse diameter of the dirt-containing part is above point B, imagine Figure 10If the dirt-holding part in it moves upward as a whole, then the dirt that falls down along the AB section is likely to fall onto the BE section and then be discharged, rather than directly falling between the outlet EF; and if the maximum lateral diameter of the dirt-holding part is below point B, the cross-sectional area of the cavity formed by the dirt-receiving part and the first part 311 near the upper part of point B will become smaller, resulting in a decrease in the cavity volume. And in order to ensure that there is only a smooth arc surface in the BE section, the arc surface of the original dirt-holding part needs to be retracted to the BE arc surface, and the overall volume will also decrease. Therefore, comprehensively speaking, making point B the place with the largest lateral diameter of the dirt-holding part is the optimal embodiment. That is, the intersection point of the dirt-receiving part and the dirt-holding part is the place with the largest lateral diameter of the dirt-holding part, and it is the demarcation point between the first part 311 and the second part 312. In the above analysis, in order to prevent the dirt from splashing back when it falls onto the sewage discharge surface, the sewage discharge angle is within 40°, h1 is greater than h2, and the top of the first part 311 is higher than point A, that is, the dimension of the first part 311 in the vertical direction is greater than h1. Therefore, in order to prevent the dirt from splashing back, the dimension of the first part 311 in the vertical direction should be greater than the dimension of the second part 312 in the vertical direction.

[0120] As Figures 6 to 10 shown, in an embodiment of the present disclosure, the dimension of the second part 312 in the first direction is greater than its dimension in the second direction. That is, the thickness of the dirt-holding part 31 of the present disclosure in the front-rear direction is less than the width in the left-right direction. Since the tray of the base station needs to receive the floor brush of the cleaning device, that is, the base station has a dimension in the axial direction of the roller brush groove 21 that is at least greater than or equal to the axial length of the roller brush groove 21. This design of the dirt-holding part 31 can make full use of the space in the axial direction of the roller brush groove 21 of the base station. On the premise of ensuring the volume of the dirt-holding part 31 of the present disclosure, the thickness of the dirt-holding part 31 and the base 1 where it is located can be effectively reduced, which is beneficial to the miniaturization of the base station, increases the acceptance and favorability of users, and thus facilitates the layout of the cleaning base station 10 of the present disclosure.

[0121] The sewage discharge outlets of existing cleaning base stations are mostly arranged on the back of the base station, and a horizontal extension pipe is externally connected to the sewage discharge outlet to the water outlet. In this way, the dirt discharged from the sewage discharge tank flows through a turn to reach the sewage discharge outlet of the base station, and then passes through a turn at the sewage discharge outlet of the base station and enters the external extension pipe to flow away. The dirt has gone through two 90° turns, greatly consuming the kinetic energy of the dirt and making the sewage discharge not smooth enough.

[0122] As Figure 5 shown, in an embodiment of the present disclosure, the sewage discharge pipe 6 is configured to communicate with the bottom of the sewage discharge tank 3; the sewage discharge pipe 6 at least has a sewage discharge section 62 extending in the horizontal direction, and a connection section 61 connecting the sewage discharge section 62 and the bottom of the sewage discharge tank 3. One end of the connection section 61 is configured to extend towards the bottom of the sewage discharge tank 3 to communicate with the bottom of the sewage discharge tank 3, and the other end is configured to extend towards the sewage discharge section 62 to communicate with the sewage discharge section 62, and the sewage discharge section 62 extends in the first direction.

[0123] During the operation of the cleaning base station 10 of the present disclosure, the floor brush assembly 94 of the cleaning device 90 is placed on the tray 2, and the sewage outlet 93 of the cleaning device 90 discharges dirt into the sewage tank 3 inside the base 1. The dirt will flow from the bottom of the sewage tank 3 into the connecting section 61 of the sewage pipe 6, and then flow along the sewage section 62. Since the sewage section 62 extends in the first direction, the overall width of the cleaning base station 10 can be effectively utilized to arrange the sewage section 62, thereby reducing the length of the overall cleaning base station of the present disclosure in the second direction.

[0124] Moreover, since the sewage section 62 extends in the first direction, the dirt only needs to go through one turn at the connecting section 61 during the process of flowing to the sewage section 62, and the extending direction of the sewage section 62 is consistent with that of the external extension pipe connected to the sewage outlet of the base station. Therefore, the kinetic energy loss of the dirt during the sewage discharge process can be effectively reduced, and the sewage discharge is smoother.

[0125] It can be understood that the horizontally extending sewage section 62 can extend along the horizontal direction, or not be completely parallel to the horizontal plane, or can extend gradually downward, that is, both the inclined downward extension and the horizontal extension can be the horizontal extension.

[0126] As Figure 1 、 Figure 5 、 Figure 6 shown, in an embodiment of the present disclosure, the sewage section 62 has a sewage outlet 620, and the sewage outlet 620 is located on the side surface of the base 1. The side surface of the base 1 is the surface of the base 1 in the first direction. In this way, the sewage outlet 620 of the sewage section 62 can be formed on the side surface of the base 1, that is, the surface of the base 1 in the first direction. The sewage outlet 620 is used to communicate with the sewer pipe 64. In this way, it is convenient for the cleaning base station 10 of the present disclosure to be connected to the sewer pipe 64 from the side, the overall pipeline installation is convenient, and it is also beneficial to reduce the occupied volume of the cleaning base station 10 of the present disclosure. Moreover, since the sewage outlet 620 is located on the side surface of the base 1, and the side surface of the base 1 is the surface of the base 1 in the first direction, it is convenient to make the extending direction of the sewage section 62 consistent with that of the external extension pipe connected to the sewage outlet 620 of the base station, effectively reducing the kinetic energy loss of the dirt during the sewage discharge process, and the sewage discharge is smoother.

[0127] As Figure 3 shown, in an embodiment of the present disclosure, the cleaning base station 10 further includes a contraction part 34. The second part 312 is communicated with the contraction part 34, and the contraction part 34 is communicated with the sewage pipe 6. The sewage pipe 6 forms a sewage outlet communicating with the sewer on the side surface of the cleaning base station 10. The contraction part 34 has a tapered structure with a smaller cross-sectional area from top to bottom, and the slope of the inner wall surface of the contraction part 34 is greater than that of the inner wall surface of the second part 312.

[0128] That is, the sewage discharge pipe 6 is connected to the bottom outlet of the sewage discharge tank 3 through the contraction part 34. The area of the bottom outlet of the sewage discharge tank 3 is larger than the area of the pipe orifice of the sewage discharge pipe 6. The contraction part 34 is vertically arranged in the base station, and its cross-sectional area gradually decreases from top to bottom to connect the bottom outlet of the sewage discharge tank 3 with the sewage discharge pipe 6 having a smaller pipe orifice. The slope of the arc surface of the contraction part 34 is greater than the slope of the arc surface of the second part 312, so that the dirt falling from the bottom outlet of the sewage discharge tank 3 can directly fall onto the pipe orifice of the sewage discharge pipe 6, minimizing the probability of the dirt falling on the wall surface of the contraction part 34 and reducing the potential energy loss. The contraction part 34 enables the dirt to pass through two different arc surfaces from point B to the pipe orifice of the sewage discharge pipe 6, gradually contracting, rather than directly and smoothly contracting from point B to the pipe orifice of the sewage discharge pipe 6, increasing the volume of the lower part, which is beneficial to reducing the thickness of the base station. Moreover, the slopes of the two arc surfaces gradually increase, which is beneficial to the dirt directly falling onto the pipe orifice of the sewage discharge pipe 6, increasing the smoothness of sewage discharge and avoiding potential energy loss caused by the dirt colliding with the arc surface.

[0129] As Figure 5 shown, the cleaning base station of the present disclosure further includes a sewage discharge assisting device 70. The output port 701 of the sewage discharge assisting device 70 is configured to be arranged at a position corresponding to the connection section 61, and is configured to provide a pressure source to at least the area of the connection section 61 through the output port 701.

[0130] In order to prevent solid dirt in the dirt from depositing in the sewage discharge section 62 of the sewage discharge pipe 6 and causing blockage of the sewage discharge pipe 6, the sewage discharge assisting device 70 can provide a pressure source to at least the area of the connection section 61 through the output port 701, thereby increasing the flow velocity of the dirt in the sewage discharge section 62 of the sewage discharge pipe 6 and preventing solid dirt in the dirt from depositing in the sewage discharge section 62 and causing blockage of the sewage discharge pipe 6. This not only ensures that the cleaning base station 10 of the present disclosure can normally discharge the dirt in the cleaning device 90 to the outside such as the sewer, but also can prevent blockage of the sewage discharge pipe 6, avoiding the user having to manually clean the blocked sewage discharge pipe 6, effectively reducing the user's usage burden and improving the user's usage experience.

[0131] In an embodiment of the present disclosure, the sewage discharge assisting device 70 is configured to provide a positive pressure source to the area of the connection section 61. That is, when the sewage discharge assisting device 70 provides a positive pressure source to the area of the connection section 61, it can push the dirt to accelerate the flow in the connection section 61 of the sewage discharge pipe 6, so as to accelerate the flow along the sewage discharge section 62 of the sewage discharge pipe 6 to the outside as soon as possible. It can be understood that when the sewage discharge assisting device 70 provides a positive pressure source to the area of the connection section 61, it can be arranged in the connection section 61 or at the rear side of the connection section 61 in the dirt flow direction, such as in the sewage discharge tank 3, etc.

[0132] In another embodiment of the present disclosure, the sewage discharge assisting device 70 is configured to provide a negative pressure source to the area of the connecting section 61. This can accelerate the flow of sewage within the connecting section 61 of the sewage discharge pipe 6 through the suction force generated by the negative pressure, and can also accelerate the flow of sewage along the sewage discharge section 62 of the sewage discharge pipe 6 as quickly as possible until it is discharged to the outside. It is understood that when the sewage discharge assisting device 70 provides a negative pressure source to the area of the connecting section 61, it can be disposed within the connecting section 61 or located on the front side of the connecting section 61 in the direction of sewage flow, such as within the sewage discharge section 62 or at the outlet of the sewage discharge section 62.

[0133] Specifically, such as Figure 5 As shown, in one embodiment of the present disclosure, the output port 701 of the sewage discharge assisting device 70 is configured to be located on a side of the connecting section 61 opposite the sewage discharge section 62. The pressure source provided by the sewage discharge assisting device 70 is configured to be output through the output port 701 and the connecting section 61 toward the sewage discharge section 62. Thus, during operation of the sewage discharge assisting device 70, the pressure provided by the sewage discharge assisting device 70 can be output from the connecting section 61 toward the sewage discharge section 62 through the output port 701, thereby promoting the movement of dirt from the connecting section 61 toward the sewage discharge section 62, thereby accelerating the flow of dirt within the sewage discharge pipe 6.

[0134] like Figure 5 As shown, in one embodiment of the present disclosure, the central axis of the output port 701 is configured to be parallel to the central axis of the sewage discharge section 62. Since the central axis of the output port 701 is parallel to the central axis of the sewage discharge section 62, the sewage discharge assisting device 70 can output pressure along the extension direction of the sewage discharge section 62. In the process of accelerating the flow of sewage in the sewage discharge pipe 6, the sewage is prevented from rotating in the sewage discharge section 62 as much as possible, thereby allowing the sewage to be discharged from the sewage discharge section 62 as quickly as possible.

[0135] Furthermore, in one embodiment of the present disclosure, the connecting section 61 is constructed to be arc-shaped; the orthographic projection of the output port 701 of the sewage discharge assisting device 70 in the first direction is configured to at least partially overlap with the orthographic projection of the inner cavity of the sewage discharge section 62 in the first direction.

[0136] Because the connecting section 61 is constructed in an arcuate shape, dirt can flow downward into the connecting section 61 under the action of gravity and then flow along the inner cavity of the connecting section 61 into the sewage discharge section 62. Because the orthographic projection of the output port 701 of the sewage discharge assisting device 70 in the extension direction of the sewage discharge section 62 is configured to at least partially overlap with the orthographic projection of the inner cavity of the sewage discharge section 62 in the extension direction, the pressure source output by the sewage discharge assisting device 70 can be directly applied to the dirt in the inner cavity of the sewage discharge section 62, thereby effectively improving the utilization efficiency of the pressure source output by the sewage discharge assisting device 70 and maximally accelerating the flow of dirt.

[0137] Specifically, as Figure 5 shown, in an embodiment of the present disclosure, the sewage discharge assisting device 70 is a jet assembly 7. The jet assembly 7 includes a jet member 72 having a jet outlet 71. The jet member 72 is configured to discharge pressurized fluid through the jet outlet 71. The opening direction of the jet outlet 71 is configured to face the first direction, and the fluid flowing out of the jet outlet 71 flows along the first direction. That is, during the operation of the jet assembly 7, the jet member 72 of the jet assembly 7 can discharge pressurized fluid from the jet outlet 71 in the first direction, and the pressurized fluid can flow along the first direction to push the dirt to accelerate the flow in the connection section 61 of the sewage discharge pipe 6, so as to accelerate the flow in the sewage discharge section 62 of the sewage discharge pipe 6 as soon as possible and be discharged to the outside.

[0138] It can be understood that if a jet member is added to an existing cleaning base station to assist in sewage discharge, since the jet member is directly facing the sewage discharge port on the back of the base station, the distance from the jet member to the sewage discharge outlet is very short, and the water flow ejected from the jet member is blocked by the turning part of the sewage discharge port of the base station, making it difficult to play a role in assisting sewage discharge. In the cleaning base station of the present disclosure, since the jet member 72 of the jet assembly 7 can discharge pressurized fluid from the jet outlet 71 in the first direction, the pressurized fluid can be ejected without being blocked, extending the assisting path of the pressurized fluid and maximizing the role of assisting sewage discharge.

[0139] It can be understood that, as Figure 5 shown, the pressurized fluid can be pressurized liquid. After flowing in from the jet inlet, the pressurized liquid can merge into the dirt in the connection section 61 and push the dirt to flow along the sewage discharge section 62 in the direction of the outlet of the sewage discharge section 62 under the action of its own kinetic energy. In another embodiment of the present disclosure, the pressure source can also be pressurized gas, and the pressurized gas can also push the dirt to flow along the sewage discharge section 62 in the direction of the outlet of the sewage discharge section 62 under the action of its own air pressure. The principle is similar and will not be elaborated here.

[0140] Specifically, as Figure 5 shown, in an embodiment of the present disclosure, a pipe joint 630 is provided on the side of the connection section 61 opposite to the sewage discharge section 62. The jet member 72 is configured to be installed in the pipe joint 630, and the jet outlet 71 is configured to face the directions of the connection section 61 and the sewage discharge section 62. That is, during the processing of the connection section 61, a pipe joint 630 needs to be processed on the side of the connection section 61 opposite to the sewage discharge section 62. When installing the jet member 72, install the jet member 72 in the pipe joint 630 and make the jet outlet 71 face the directions of the connection section 61 and the sewage discharge section 62, so as to ensure that after the pressurized fluid flows out of the jet outlet 71, it can flow along the pipe joint 630 to the side where the sewage discharge section 62 is located, thereby pushing the dirt to flow along the sewage discharge section 62 in the direction of the outlet of the sewage discharge section 62.

[0141] Further, as Figure 5As shown, in one embodiment of the present disclosure, the pipe joint 630 is a sleeve 63, and the jet member 72 is configured to be installed inside the sleeve 63; the bottom of the sleeve 63 is configured to be higher than the bottom of the sewage discharge section 62, and the top of the sleeve 63 is configured to be lower than the top of the sewage discharge section 62.

[0142] Since the bottom of the sleeve 63 is higher than the bottom of the sewage discharge section 62 and the top of the sleeve 63 is lower than the top of the sewage discharge section 62, after the jet member 72 is installed inside the sleeve 63, it can be ensured that the bottom of the jet outlet 71 is higher than the bottom of the sewage discharge section 62 and the top of the jet outlet 71 is lower than the top of the sewage discharge section 62. After the pressurized fluid flows out of the sleeve 63, it can directly impact the dirt in the sewage pipe 6 and push the dirt to flow along the rear section of the connection section 61 towards the sewage discharge section 62; the pressurized fluid will not impact the inner cavity wall or other positions of the connection section 61, thereby effectively avoiding the waste of the kinetic energy of the pressurized fluid, improving the effect of the jet assembly 7 in pushing the dirt to flow, and preventing the dirt from blocking the sewage pipe 6.

[0143] Further, as Figure 5 shown, in one embodiment of the present disclosure, the sleeve 63 is configured to extend away from the sewage discharge section 62 from the inner wall of the connection section 61, and the opening of the sleeve 63 on the inner wall of the connection section 61 is configured to be adapted to the shape of the inner wall of the connection section 61. Since the sleeve 63 extends away from the sewage discharge section 62 from the inner wall of the connection section 61 and the opening of the sleeve 63 on the inner wall of the connection section 61 is adapted to the shape of the inner wall of the connection section 61, the sleeve 63 will not extend into the interior of the connection section 61, and the dirt will not be blocked by the sleeve 63 during the flow along the connection section 61, thereby ensuring that the dirt can flow smoothly along the connection section 61 and, during the process of flowing through the opening of the sleeve 63, under the pushing action of the pressurized fluid, accelerate towards the sewage discharge section 62.

[0144] As Figure 5 shown, in one embodiment of the present disclosure, a fluid pipeline communicating with the jet member 72 is provided on the base 1, and the fluid is configured to flow into the jet member 72 through the fluid pipeline under the action of the power source device. In this way, during the process of the jet assembly 7, the fluid can be pressurized under the action of the power source device and then flow into the jet member 72 through the fluid pipeline, and then flow out from the jet outlet 71 of the jet member 72. It can be understood that the fluid can be a medium fluid such as tap water or cleaning liquid, and can come from an external water source such as a tap water faucet, or can come from a water tank or cleaning liquid tank inside the base station. The power source device can be a related device such as a water pump, which is not limited herein.

[0145] In another embodiment of the present disclosure, a fluid pipeline communicating with the jet member 72 is provided on the base 1. The fluid pipeline is configured to be docked with a water tap, and the fluid in the water tap is configured to flow into the jet member 72 through the fluid pipeline under the action of its own water pressure. It can be understood that since the water tap has its own water pressure, when the fluid pipeline is docked with the water tap, the fluid in the water tap can flow into the jet member 72 through the fluid pipeline under the action of its own water pressure, and then flow out from the jet outlet 71 of the jet member 72.

[0146] As Figure 5 shown, in an embodiment of the present disclosure, the jet member 72 includes a jet pipe 721, and the jet outlet 71 is arranged on the end face of the jet pipe 721; the jet member 72 further includes a Venturi tube 722 located inside the jet pipe 721, and the fluid is configured to be discharged from the jet outlet 71 after passing through the Venturi tube 722.

[0147] That is, during the operation of the jet assembly 7, when the pressurized fluid of the jet assembly 7 flows into the jet pipe 721 of the jet member 72, it will flow through the Venturi tube 722 inside the jet pipe 721, and then be discharged from the jet outlet 71. After the pressurized fluid flows through the Venturi tube 722, it can have a relatively high flow rate and good stability. Among them, when the total flow area of the jet outlet 71 is smaller than the area of the minimum flow cross-section of the Venturi tube 722, a larger flow rate can be obtained for the sewage jet, thereby improving the acceleration efficiency of the pressurized fluid on the dirt.

[0148] As Figure 5 shown, in an embodiment of the present disclosure, the jet member 72 is configured to be located on one side of the connection section 61 opposite to the sewage section 62, and the opening direction of the jet outlet 71 is configured to face the extending direction of the sewage section 62; the jet outlet 71 at least partially overlaps with the inner cavity of the sewage section 62 in the height direction.

[0149] Since the jet member 72 is located on one side of the connection section 61 opposite to the sewage section 62, and the opening direction of the jet outlet 71 faces the extending direction of the sewage section 62; the jet outlet 71 at least partially overlaps with the inner cavity of the sewage section 62 in the height direction, it can be ensured that after the pressurized fluid output by the jet assembly 7 flows out from the jet outlet 71, it can flow in the extending direction of the sewage section 62 towards the direction where the sewage section 62 is located, so as to impact the dirt in the connection section 61 and directly push the dirt to flow along the rear section of the connection section 61 towards the sewage section 62, thereby effectively improving the pressure utilization efficiency of the pressurized fluid and accelerating the flow process of the dirt as much as possible.

[0150] As Figure 5As shown, in one embodiment of the present disclosure, the central axis of the jet outlet 71 is configured to be parallel to the central axis of the sewage discharge section 62. Since the central axis of the jet outlet 71 is parallel to the central axis of the sewage discharge section 62, the pressurized fluid flowing out of the jet outlet 71 can flow along the central axis of the sewage discharge section 62. When the pressurized fluid pushes the dirt to flow in the sewage discharge pipe 6, the dirt is prevented from rotating in the sewage discharge section 62 as much as possible, thereby allowing the dirt to be discharged from the sewage discharge section 62 as quickly as possible.

[0151] It can be understood that the central axis of the jet outlet 71 refers to the axis obtained along the extension direction of the jet outlet 71 through the center point between the highest point and the lowest point of the jet outlet 71. The jet outlet 71 can be symmetrically arranged as a whole in the upper and lower parts, or it can be asymmetrically arranged, which is not limited here.

[0152] Further, such as Figure 5 As shown, in one embodiment of the present disclosure, the central axis of the jet outlet 71 is configured to be higher than the central axis of the sewage discharge section 62. It is understood that, under the influence of gravity, the pressurized fluid will fall a certain distance when flowing from the jet outlet 71 into the sewage discharge pipe 6, that is, the center position of the pressurized fluid entering the sewage discharge pipe 6 is lower than the center position of the jet outlet 71.

[0153] Therefore, when the center axis of the jet outlet 71 is higher than the center axis of the sewage section 62, the center position of the pressurized fluid entering the sewage pipe 6 can be located near the center axis of the sewage section 62, thereby ensuring that the pressurized fluid can impact the dirt into the sewage section 62 at the center position, avoiding the dirt from rotating along the axial direction of the sewage pipe 6 during the flow along the sewage pipe 6 under the action of the pressurized fluid and being retained in the sewage pipe 6 and unable to be discharged quickly, thereby accelerating the flow speed of the dirt along the sewage pipe 6, which is conducive to the discharge of dirt from the sewage pipe.

[0154] like Figure 5 As shown, in one embodiment of the present disclosure, the top of the jet outlet 71 is constructed to be lower than the top of the inner cavity of the sewage discharge section 62. Since the top of the jet outlet 71 is lower than the top of the inner cavity of the sewage discharge section 62, after the pressurized fluid flows out of the jet outlet 71, the fluid located at the upper portion of the jet outlet 71 can directly impact the dirt in the sewage discharge pipe 6 and push the dirt along the rear section of the connecting section 61 toward the inner cavity of the sewage discharge section 62, without impacting the dirt to a position on the connecting section 61 that is higher than the top of the inner cavity of the sewage discharge section 62. This effectively avoids the waste of kinetic energy of the pressurized fluid, thereby improving the effect of the jet assembly 7 in pushing the dirt to flow and preventing the dirt from clogging the sewage discharge pipe 6.

[0155] Similar, such as Figure 5As shown, in an embodiment of the present disclosure, the bottom end of the jet outlet 71 is configured to be higher than the bottom end of the inner cavity of the sewage discharge section 62. Since the bottom end of the jet outlet 71 is higher than the bottom end of the inner cavity of the sewage discharge section 62, after the pressurized fluid flows out from the jet outlet 71, the fluid located below the jet outlet 71 can directly impact the dirt in the sewage discharge pipe 6 and push the dirt to move along the rear section of the connection section 61 towards the inner cavity of the sewage discharge section 62, without impacting the dirt to a position on the connection section 61 that is lower than the bottom end of the inner cavity of the sewage discharge section 62, and can also effectively avoid the waste of the kinetic energy of the pressurized fluid, thereby improving the effect of the jet assembly 7 in pushing the dirt to flow and preventing the dirt from blocking the sewage discharge pipe 6.

[0156] As Figure 13 and Figure 14 shown, in an embodiment of the present disclosure, a plurality of jet outlets 71 are provided, and the plurality of jet outlets 71 are configured to be uniformly arranged on the end face of the jet member 72. Since a plurality of jet outlets 71 are provided and the plurality of jet outlets 71 are uniformly arranged on the end face of the jet member 72, the pressurized fluid flowing out from each jet outlet 71 can jointly push the dirt, so that the dirt in the sewage discharge pipe 6 has a larger force-bearing surface and is more evenly stressed, and can enable the dirt in all circumferential locations to be subjected to the thrust from the pressurized fluid and flow towards the outlet of the sewage discharge pipe 6, avoiding the situation where only some dirt accelerates and some dirt does not accelerate, resulting in the deposition of solid dirt in the sewage discharge pipe 6.

[0157] Specifically, as Figure 13 and Figure 14 shown, in an embodiment of the present disclosure, the jet outlet 71 includes a central outlet 711 located at the center of the jet member 72 and edge outlets 712 provided at the edge of the jet member 72. There are at least two edge outlets 712, located on at least both sides of the central outlet 711, and each edge outlet 712 is configured to surround the central outlet 711. In this way, the pressurized fluid ejected from the central outlet 711 can impact the central part of the dirt in the sewage discharge pipe 6, and the pressurized fluid ejected from the edge outlets 712 can impact the circumferential edge part of the dirt in the sewage discharge pipe 6, thereby ensuring that the dirt at the central position and the edge position in the sewage discharge pipe 6 can be pushed and accelerated by the pressurized fluid, so that the dirt in the sewage discharge pipe 6 is more evenly stressed, which is beneficial to the flow of the dirt and avoids the deposition of solid dirt in the sewage discharge pipe 6.

[0158] As Figure 13 and Figure 14As shown, in one embodiment of the present disclosure, the size of the center outlet 711 is constructed to be larger than the size of each edge outlet 712. In this way, the thrust exerted on the dirt in the center part of the sewage pipe 6 can be greater than the thrust exerted on the dirt in the edge part, so that the flow speed of the dirt in the center part can be faster than the flow speed of the dirt in the edge part, thereby effectively improving the kinetic energy utilization efficiency of the pressurized fluid and reducing kinetic energy waste.

[0159] In another embodiment of the present disclosure, the inner diameter of the central outlet 711 is constructed to be equal to the size of each edge outlet 712. In this way, the thrust exerted on the dirt in the central part of the sewage pipe 6 is relatively balanced with the thrust exerted on the dirt in the edge part, so that the dirt in the sewage pipe 6 can be accelerated as a whole to avoid the slow flow speed of some dirt and prevent the solid dirt in some dirt from being deposited in the sewage pipe 6.

[0160] It is understandable that if Figure 5 As shown, in one embodiment of the present disclosure, the central axis of the central outlet 711 is configured to be parallel to the central axis of the sewage discharge section 62. Since the central axis of the central outlet 711 is parallel to the central axis of the sewage discharge section 62, the pressurized fluid flowing out of the central outlet 711 can flow along the central axis of the sewage discharge section 62. When this pressurized fluid pushes the sewage to flow in the sewage discharge pipe 6, the sewage is prevented from rotating in the sewage discharge section 62 as much as possible, thereby allowing the sewage to be discharged from the sewage discharge section 62 as quickly as possible.

[0161] like Figure 14 As shown, in one embodiment of the present disclosure, the cross-sectional shape of the jet outlet 71 is configured as a circle. Since the cross-sectional shape of the jet outlet 71 is a circle, the pressure of the pressurized fluid is relatively balanced when it flows out of the circular jet outlet 71, and the flow rate attenuation is also minimal.

[0162] like Figure 5 As shown, in one embodiment of the present disclosure, the jet assembly 7 extends along the first direction. Since the jet assembly 7 extends along the first direction, it can be ensured that there is no kinetic energy loss when the pressurized fluid is ejected along the first direction.

[0163] In order to control the operation of the sewage discharge assisting device 70 of the present disclosure, the control unit of the present disclosure is configured to control the sewage discharge assisting device 70 to start during the process of sewage discharge from the sewage chute 3, at the beginning of sewage discharge, or before sewage discharge. In this way, during the process of sewage discharge from the sewage chute 3, at the beginning of sewage discharge, or before sewage discharge, the control unit controls the sewage discharge assisting device 70 to start. During the process of sewage discharge from the cleaning device 90, the sewage discharge assisting device 70 can continuously provide a pressure source to the area of the connecting section 61 through the output port 701, ensuring that during the process of sewage discharge from the cleaning device 90, the sewage can increase its flow speed in the sewage pipe 6 under the action of the sewage discharge assisting device 70, completely preventing solid dirt in the sewage from being deposited in the sewage discharge section 62, thereby avoiding clogging of the sewage pipe 6.

[0164] In another embodiment of the present disclosure, the control unit controls the activation of the drainage assist device 70 when the dirt in the drainage trough 3 reaches a predetermined level. Specifically, the drainage assist device 70 is activated only when the amount of dirt in the drainage trough 3 is high, the dirt is discharged slowly, and there is a risk of solid matter in the dirt being deposited in the drainage section 62. In this way, the drainage assist device 70 can be activated before a blockage in the drainage pipe 6 is likely to occur, thereby preventing blockage. When drainage is smooth, the drainage assist device 70 does not need to be activated, effectively saving the operation of the drainage assist device 70, conserving related resources, and reducing energy waste.

[0165] In a specific embodiment of the present disclosure, EV2 (the solenoid valve that controls the water supply to the jet assembly) is opened for 10 seconds. The 10 seconds is calculated based on a 1.5-meter sewer pipe with an inner diameter of 32 mm and a length of 1.5 m. The water flow of the jet component is 8 L / min (the minimum flushing flow rate for laboratory testing). The amount of water required to push dirt from the head to the tail of the sewer pipe is approximately the volume of the entire sewer pipe {3.14*(32 / 2)^2*1500}=1,205,760 mm^3. The calculation time is (1,205,760 / 8000000*60)=9.04 seconds. Considering the length of the sewer pipe, the opening time of the jet component is set to 10 seconds, that is, the single flushing time is 10 seconds, and it will be disconnected if it exceeds 12 seconds.

[0166] Open the drain plate and the jet component at the same time. If the drain plate is not opened for the first time, the jet component will be closed. At this time, the jet component will work for the first time until the drain plate is detected to be open for the second time, and continue to work for the second time. The first time + the second time = 10s.

[0167] like Figures 10 to 12As shown, in an embodiment of the present disclosure, the cleaning base station 10 includes a self-cleaning assembly 5 located in the sewage discharge tank 3, and the self-cleaning assembly 5 is configured to be located at a position higher than the end face of the sewage receiving port 321; the self-cleaning assembly 5 is configured to output cleaning liquid into the inner cavities of the sewage containing part 31 and / or the sewage receiving part 32.

[0168] In this way, during the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning device 90 is discharged into the sewage discharge tank 3 and discharged from the sewage discharge pipe 6, the self-cleaning assembly 5 can output cleaning liquid into the inner cavities of the sewage containing part 31 and / or the sewage receiving part 32, so as to clean the inner walls of the sewage containing part 31 and / or the sewage receiving part 32, and prevent dirt from remaining on the inner walls of the sewage containing part 31 and / or the sewage receiving part 32. Moreover, since the sewage discharge tank 3 mainly uses the sewage receiving part 32 to receive the dirt from the cleaning device 90, the self-cleaning assembly 5 is located at a position higher than the end face of the sewage receiving port 321, and the sewage receiving part 32 is lower than the sewage containing part 31. When the self-cleaning assembly 5 cleans the sewage discharge tank 3, the sewage receiving part 32 can be fully cleaned to prevent cleaning dead corners in the sewage discharge tank 3.

[0169] As Figure 10 shown, in an embodiment of the present disclosure, the self-cleaning assembly 5 is located at the top of the sewage discharge tank 3, and the self-cleaning assembly 5 is configured to output cleaning liquid into the inner cavity of the sewage containing part 31 from the top of the sewage containing part 31, and output cleaning liquid to the top and the inner cavity of the sewage receiving part 32 from the top of the sewage containing part 31. In this way, during the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning device 90 is discharged into the sewage discharge tank 3 and discharged from the sewage discharge pipe 6, the self-cleaning assembly 5 can output cleaning liquid into the inner cavity of the sewage containing part 31 from the top of the sewage containing part 31, and output cleaning liquid to the top and the inner cavity of the sewage receiving part 32 from the top of the sewage containing part 31, so as to clean the inner cavities of the sewage containing part 31 and the sewage receiving part 32, prevent dirt from remaining on the inner cavities of the sewage containing part 31 and the sewage receiving part 32, ensure that the sewage discharge tank 3 of the present disclosure is clean and odorless, and thus effectively improve the user experience.

[0170] Moreover, since the self-cleaning assembly 5 can output cleaning liquid into the inner cavity of the sewage containing part 31 and the inner cavity of the sewage receiving part 32 from the top of the sewage containing part 31, there is no need to separately provide a cleaning mechanism for the sewage containing part 31 and the sewage receiving part 32, which can effectively simplify the water circuit structure of the cleaning base station 10 of the present disclosure and promote the miniaturization of the cleaning base station 10 of the present disclosure.

[0171] As Figure 10 、 Figure 15 、 Figure 16 、 Figure 20As shown, in an embodiment of the present disclosure, the self-cleaning assembly 5 includes a dirt-containing cleaning member 51, a dirt-receiving cleaning member 52, and a liquid inlet pipe 53. The dirt-containing cleaning member 51 is disposed at the top of the inner cavity of the dirt-containing portion 31 and is configured to output cleaning liquid into the inner cavity of the dirt-containing portion 31. The dirt-receiving cleaning member 52 is disposed at the top of the inner cavity of the dirt-receiving portion 32 and is configured to output cleaning liquid into the inner cavity of the dirt-receiving portion 32. The liquid inlet pipe 53 is connected to the dirt-containing cleaning member 51 and the dirt-receiving cleaning member 52. The cleaning liquid flowing into the liquid inlet pipe 53 is configured to partially flow into the dirt-containing cleaning member 51 and partially flow to the dirt-receiving cleaning member 52.

[0172] Thus, during the operation of the cleaning base station 10 of the present disclosure, the cleaning liquid flowing into the liquid inlet pipe 53 is configured to partially flow into the dirt-containing cleaning member 51 and partially flow to the dirt-receiving cleaning member 52. The cleaning liquid flowing into the dirt-containing cleaning member 51 can output cleaning liquid into the inner cavity of the dirt-containing portion 31 from the top of the inner cavity of the dirt-containing portion 31, thereby cleaning the inner cavity of the dirt-containing portion 31. The cleaning liquid flowing into the dirt-receiving cleaning member 52 can output cleaning liquid into the inner cavity of the dirt-receiving portion 32 from the top of the inner cavity of the dirt-receiving portion 32, thereby cleaning the inner cavity of the dirt-containing portion 31. In this way, only one liquid inlet pipe 53 needs to be provided to supply cleaning liquid to the dirt-containing cleaning member 51 and the dirt-receiving cleaning member 52 at the same time, thereby effectively simplifying the water circuit structure of the cleaning base station 10 of the present disclosure.

[0173] Specifically, as Figure 10 shown, in an embodiment of the present disclosure, a liquid inlet cavity 54 communicating with the liquid inlet pipe 53 is provided on the outer wall of the top of the dirt-containing portion 31. Among them, the dirt-containing cleaning member 51 is configured to be disposed at a position corresponding to the liquid inlet cavity 54 and communicate with the liquid inlet cavity 54. The dirt-receiving cleaning member 52 includes a liquid discharge section 521 and a liquid inlet section 522. The liquid discharge section 521 is used to output cleaning liquid into the inner cavity of the dirt-receiving portion 32. The liquid inlet section 522 is configured to connect the liquid inlet cavity 54 and the liquid discharge section 521.

[0174] That is, during the operation of the cleaning base station 10 of the present disclosure, the cleaning liquid flowing into the liquid inlet pipe 53 will enter the liquid inlet cavity 54. Part of the cleaning liquid in the liquid inlet cavity 54 will flow into the dirt-containing cleaning member 51, and the remaining part of the cleaning liquid in the liquid inlet cavity 54 will flow along the liquid inlet section 522 to the liquid discharge section 521, thereby achieving the purpose of supplying cleaning liquid to the dirt-containing cleaning member 51 and the liquid discharge section 521 at the same time. The overall liquid inlet structure is simple, and the flow of the cleaning liquid is relatively smooth.

[0175] As Figure 10As shown, in one embodiment of the present disclosure, a cover plate 55 is provided on the outer wall of the dirt-containing part 31. The cover plate 55 is buckled on the outer wall of the dirt-containing part 31 and encloses a liquid inlet cavity 54 with the outer wall of the dirt-containing part 31. The liquid inlet pipe 53 is provided on the cover plate 55. In this way, the liquid inlet cavity 54 can be formed between the cover plate 55 buckled on the outer wall of the dirt-containing part 31 and the dirt-containing part 31, and the liquid inlet pipe 53 is provided on the cover plate 55, which can be directly communicated with the liquid inlet cavity 54 without setting other connecting pipe fittings, thus further simplifying the liquid inlet structure.

[0176] Specifically, as Figure 10 shown, in one embodiment of the present disclosure, a through hole 56 is provided on the outer wall of the dirt-containing part 31 corresponding to the position of the liquid inlet cavity 54. The liquid inlet cavity 54 is configured to be communicated with the dirt-containing and cleaning part 51 through the through hole 56. In this way, when the cleaning liquid flows from the liquid inlet pipe 53 into the liquid inlet cavity 54, it can flow to the dirt-containing and cleaning part 51 through the through hole 56, that is, to the top of the inner cavity of the dirt-containing part 31, and then clean the inner cavity of the dirt-containing part 31.

[0177] As Figure 10 shown, in one embodiment of the present disclosure, the dirt-containing part 31 includes a first part 311 located above and a second part 312 located below. The first part 311 is configured to be docked with the second part 312; the size of the first part 311 is configured to be a gradually expanding structure with an increasing cross-sectional area from top to bottom; the dirt-containing and cleaning part 51 is arranged at the central position of the inner cavity of the first part 311 of the dirt-containing part 31 and is configured to output cleaning liquid radially around.

[0178] Since the first part 311 of the dirt-containing part 31 located above is a gradually expanding structure with an increasing cross-sectional area from top to bottom, and the dirt-containing and cleaning part 51 is arranged at the central position of the inner cavity of the first part 311 of the dirt-containing part 31, when the dirt-containing and cleaning part 51 outputs cleaning liquid radially around, it can clean all circumferential parts of the inner cavity of the dirt-containing part 31, avoiding cleaning dead corners in the dirt-containing part 31.

[0179] As Figure 9 shown, in one embodiment of the present disclosure, the top of the dirt-receiving part 32 is configured to form a dirt-receiving port 321 extending outward from the dirt-containing part 31 for docking with the sewage outlet 93 of the cleaning device 90. The dirt-receiving and cleaning part 52 is configured to at least partially surround the circumferential side wall of the dirt-receiving port 321 and is configured to output cleaning liquid from at least part of the circumference of the dirt-receiving port 321. In this way, since the dirt-receiving and cleaning part 52 at least partially surrounds the circumferential side wall of the dirt-receiving port 321 and outputs cleaning liquid from at least part of the circumference of the dirt-receiving port 321, the dirt-receiving and cleaning part 52 can clean at least part of the circumferential side wall of the dirt-receiving part 32, reduce the residue of dirt on the circumferential side wall of the dirt-receiving part 32, and reduce the odor formed by the dirt residue of the cleaning base station 10 of the present disclosure.

[0180] Specifically, as Figure 7 shown, in an embodiment of the present disclosure, the sewage receiving part 32 includes an enclosing wall 322 on the side away from the sewage containing part 31, and the enclosing wall 322 is configured to extend obliquely downward from the top of the sewage receiving part 32 to dock with the corresponding position of the sewage containing part 31; the sewage receiving part 32 further includes a first side wall 323 and a second side wall 324 located on both sides of the enclosing wall 322, and the first side wall 323, the second side wall 324, and the enclosing wall 322 are configured to enclose the sewage receiving part 32 on the sewage containing part 31; the sewage receiving and cleaning member 52 is configured to be located at the top of the first side wall 323, the second side wall 324, and the enclosing wall 322, and is configured to output cleaning liquid downward from the top of the first side wall 323, the second side wall 324, and the enclosing wall 322.

[0181] In this way, the sewage receiving and cleaning member 52 can output cleaning liquid downward from the top of the first side wall 323, the second side wall 324, and the enclosing wall 322, so as to ensure that the sewage receiving and cleaning member 52 can clean the first side wall 323, the second side wall 324, and the enclosing wall 322 of the sewage receiving part 32, avoid the residue of dirt on the first side wall 323, the second side wall 324, and the enclosing wall 322 of the sewage receiving part 32, and minimize the odor formed by the dirt residue in the cleaning base station 10 of the present disclosure.

[0182] Further, as Figure 7 shown, in an embodiment of the present disclosure, the end face where the sewage receiving port 321 is located is configured to extend on a horizontal plane or obliquely downward from the position connected to the sewage containing part 31; the sewage receiving and cleaning member 52 is configured to be arranged along the end face of the sewage receiving port 321. Since the sewage receiving and cleaning member 52 is arranged along the end face of the sewage receiving port 321, the cleaning liquid output by the sewage receiving and cleaning member 52 can flow downward from the end face of the sewage receiving port 321, avoiding cleaning dead corners in the sewage receiving part 32.

[0183] As Figures 10 to 12 shown, in an embodiment of the present disclosure, the sewage discharge groove 3 includes a sewage receiving part 32 having a sewage receiving port 321, and the sewage receiving port 321 is configured to dock with the sewage discharge port 93 of the cleaning device 90; the sewage receiving and cleaning member 52 is arranged around the sewage receiving port 321 and is configured to output cleaning liquid into the inner cavity of the sewage receiving part 32; the sewage receiving and cleaning member 52 includes a liquid inlet section 522 and a liquid discharge section 521, and the liquid discharge section 521 is configured to communicate with the liquid inlet section 522 and is arranged at a position lower than the liquid inlet section 522; the cleaning liquid is configured to flow from the liquid inlet section 522 to the liquid discharge section 521 and is configured to flow from the liquid discharge section 521 into the inner cavity of the sewage receiving part 32.

[0184] In this way, during the operation of the cleaning base station 10 of the present disclosure, the dirt discharged from the sewage outlet 93 of the cleaning device 90 enters the sewage trough 3 from the sewage receiving port 321 of the sewage receiving part 32, and after being discharged from the sewage pipeline 6, the sewage receiving and cleaning member 52 can output cleaning liquid to the inner cavity of the sewage receiving part 32 to clean the inner cavity of the sewage receiving part 32. Since the sewage receiving and cleaning member 52 is arranged around the sewage receiving port 321, when the sewage receiving and cleaning member 52 outputs the cleaning liquid, it can clean the inner cavity of the sewage receiving part 32, prevent dirt from remaining on the inner cavity of the sewage receiving part 32, ensure that the inside of the sewage receiving part 32 of the present disclosure is clean and odorless, and thus effectively improve the user experience.

[0185] Moreover, since the sewage receiving and cleaning member 52 includes a liquid inlet section 522 and a liquid discharge section 521, the liquid discharge section 521 is communicated with the liquid inlet section 522 and is arranged at a position lower than the liquid inlet section 522. In this way, the cleaning liquid can naturally flow from the liquid inlet section 522 to the liquid discharge section 521 under the action of its own gravity, and then flow through the liquid discharge section 521 to the inner cavity of the sewage receiving part 32 without the need for an external power source to provide power for the flow of the cleaning liquid. Thus, the power source required for the sewage receiving and cleaning member 52 can be omitted, effectively simplifying the water circuit structure of the cleaning base station 10 of the present disclosure and promoting the miniaturization of the cleaning base station 10 of the present disclosure.

[0186] Furthermore, as Figure 12 shown, in an embodiment of the present disclosure, both ends of the liquid inlet section 522 are communicated with both ends of the liquid discharge section 521, and the liquid inlet section 522 and the liquid discharge section 521 are configured to form an annular structure. Since both ends of the liquid inlet section 522 are communicated with both ends of the liquid discharge section 521 and the liquid inlet section 522 and the liquid discharge section 521 form an annular structure, the cleaning liquid entering the liquid inlet section 522 will be divided into two parts, which flow to both ends of the liquid discharge section 521 respectively, and then flow along the liquid discharge section 521 until flowing to the middle of the liquid discharge section 521. Moreover, during the process of the cleaning liquid flowing along the liquid discharge section 521, part of the cleaning liquid will flow out from the liquid discharge section 521 to the inner cavity of the sewage receiving part 32, thereby cleaning the inner cavity of the sewage receiving part 32. Since the cleaning liquid flows into the liquid discharge section 521 from both ends, not only is the required path of the cleaning liquid the shortest, the flow time is the shortest, but also the water pressure loss of the cleaning liquid is the least.

[0187] As Figure 7 and Figure 12As shown, in an embodiment of the present disclosure, the dirt receiving portion 32 includes an enclosing wall 322. The enclosing wall 322 is configured to extend obliquely downward from the top of the dirt receiving portion 32 to form a sewage discharging surface 325. The dirt receiving portion 32 further includes a first side wall 323 and a second side wall 324 located on both sides of the enclosing wall 322. The first side wall 323, the second side wall 324, and the enclosing wall 322 are configured to enclose the dirt receiving portion 32. The liquid discharging section 521 is configured to extend along the tops of the first side wall 323, the enclosing wall 322, and the second side wall 324. The cleaning liquid is configured to flow out from positions corresponding to the first side wall 323, the enclosing wall 322, and the second side wall 324 in the liquid discharging section 521. Since the liquid discharging section 521 extends along the tops of the first side wall 323, the enclosing wall 322, and the second side wall 324, and the cleaning liquid flows out from positions corresponding to the first side wall 323, the enclosing wall 322, and the second side wall 324 in the liquid discharging section 521, after the cleaning liquid flows out from positions corresponding to the first side wall 323, the enclosing wall 322, and the second side wall 324 in the liquid discharging section 521, it can clean the first side wall 323, the enclosing wall 322, and the second side wall 324, avoiding the residue of dirt on the first side wall 323, the second side wall 324, and the enclosing wall 322 of the dirt receiving portion 32, and minimizing the odor formed by the dirt residue in the cleaning base station 10 of the present disclosure.

[0188] As Figure 9 shown, in an embodiment of the present disclosure, the sewage discharging groove 3 includes a dirt containing portion 31 located in the base 1. The dirt receiving portion 32 is provided on the side wall of the dirt containing portion 31 and is communicated with the inner cavity of the dirt containing portion 31. The top of the dirt receiving portion 32 is configured to be lower than the top of the dirt containing portion 31. The liquid discharging section 521 is configured to be provided on the top of the dirt receiving portion 32, and the liquid inlet section 522 is configured to be provided at a position on the dirt containing portion 31 adjacent to the dirt receiving portion 32. Since the top of the dirt receiving portion 32 is lower than the top of the dirt containing portion 31, the liquid discharging section 521 is provided on the top of the dirt receiving portion 32, and the liquid inlet section 522 is provided at a position on the dirt containing portion 31 adjacent to the dirt receiving portion 32, the cleaning liquid can flow naturally from the position on the dirt containing portion 31 adjacent to the dirt receiving portion 32 to the liquid discharging section 521 at the top of the dirt receiving portion 32 under the action of its own gravity, without the need for an external power source to provide power for the flow of the cleaning liquid, thereby eliminating the power source required for the dirt receiving and cleaning member 52.

[0189] As Figure 12As shown, in one embodiment of the present disclosure, a liquid inlet chamber 54 is provided at the top of the dirt storage portion 31. The liquid inlet chamber 54 is configured to communicate with the middle position of the liquid inlet section 522. The cleaning liquid in the liquid inlet chamber 54 is configured to flow from the middle of the liquid inlet section 522 to both sides thereof; a flow dividing plate 523 is provided in the flow path from the liquid inlet chamber 54 to the liquid inlet section 522. The cleaning liquid in the liquid inlet chamber 54 is configured to flow to both sides of the liquid inlet section 522 through both sides of the flow dividing plate 523 respectively. In this way, the cleaning liquid in the liquid inlet chamber 54 can flow from the middle position of the liquid inlet section 522 to both sides of the liquid inlet section 522 through both sides of the flow dividing plate 523 under the blocking action of the flow dividing plate 523, thereby naturally achieving the purpose of diverting the cleaning liquid to both ends of the liquid inlet section 522.

[0190] As Figure 10 shown, in one embodiment of the present disclosure, the liquid inlet chamber 54 and the liquid inlet section 522 are higher than the liquid discharge section 521. In this way, the self-gravity of the cleaning liquid can be utilized to make the cleaning liquid flow naturally from the liquid inlet chamber 54 and the liquid inlet section 522 to the liquid discharge section 521 without the need for an external power source to provide power for the flow of the cleaning liquid, so that the power source required for the dirt-bearing cleaning member 52 can be omitted.

[0191] Specifically, as Figure 12 shown, in one embodiment of the present disclosure, the liquid inlet section 522 is higher than the liquid discharge section 521. Both ends of the liquid inlet section 522 are configured to extend downward along the wall surface of the dirt storage portion 31 to communicate with both ends of the liquid discharge section 521. Since both ends of the liquid inlet section 522 extend downward along the wall surface of the dirt storage portion 31 to communicate with both ends of the liquid discharge section 521, the cleaning liquid entering the liquid inlet section 522 can be naturally divided into two parts and flow downward along the wall surface of the dirt storage portion 31 to both ends of the liquid discharge section 521 respectively, thereby automatically providing the cleaning liquid to both ends of the liquid discharge section 521.

[0192] As Figure 10 and Figure 12 、 Figure 21 shown, in one embodiment of the present disclosure, the liquid discharge section 521 includes a diversion groove 5211 extending circumferentially along the dirt-bearing portion 32, and a diversion plate 5212 covering the diversion groove 5211. The diversion plate 5212 and the side of the diversion groove 5211 adjacent to the inner cavity of the dirt-bearing portion 32 enclose an overflow port 5213; the cleaning liquid flowing in the diversion groove 5211 is configured to flow into the inner cavity of the dirt-bearing portion 32 through the overflow port 5213. That is, the diversion plate 5212 and the dirt-bearing portion 32 enclose the diversion groove 5211, and the diversion plate 5212 and the side of the diversion groove 5211 adjacent to the inner cavity of the dirt-bearing portion 32 enclose the overflow port 5213. In this way, during the process of the cleaning liquid flowing along the diversion groove 5211, part of the cleaning liquid can continuously flow into the inner cavity of the dirt-bearing portion 32 from the overflow port 5213, thereby cleaning the inner cavity of the dirt-bearing portion 32;

[0193] After the cleaning liquid entering from both ends of the liquid drainage section 521 converges in the middle of the liquid drainage section 521, it will also flow from the corresponding overflow port 5213 into the inner cavity of the dirt receiving part 32 to clean the inner cavity of the dirt receiving part 32. Since overflow ports 5213 are formed on both the side of the guide plate 5212 and the side of the guide groove 5211 adjacent to the inner cavity of the dirt receiving part 32, and the overflow port 5213 is an annular overflow channel surrounding the first side wall 323, the second side wall 324, and the enclosing wall 322, it can ensure that the inner cavity of the dirt receiving part 32 corresponding to the guide groove 5211 can be cleaned, avoiding cleaning dead corners and preventing dirt from remaining on the inner cavity of the dirt receiving part 32.

[0194] Specifically, in an embodiment of the present disclosure, the guide groove 5211 is arranged on the outer side of the inner wall of the dirt receiving part 32, and the side of the guide plate 5212 facing the inner cavity of the dirt receiving part 32 is configured to extend from the top of the dirt receiving part 32 towards the inner cavity of the dirt receiving part 32, so as to enclose the overflow port 5213 with the top end face of the dirt receiving part 32. That is, as Figure 10 and Figure 12 shown, the guide groove 5211 is arranged on the radially outer side of the inner wall of the dirt receiving part 32, and the side of the guide plate 5212 facing the inner cavity of the dirt receiving part 32 extends from the top of the dirt receiving part 32 towards the inner cavity of the dirt receiving part 32, so as to enclose the overflow port 5213 with the top end face of the dirt receiving part 32. In this way, after the liquid level of the cleaning liquid in the guide groove 5211 exceeds the top end face of the dirt receiving part 32, it can flow out from the overflow port 5213 with an opening towards the inner cavity of the dirt receiving part 32 at the top of the guide groove 5211, and then flow into the dirt receiving part 32 to clean the dirt receiving part 32.

[0195] It can be understood that, as Figure 10 and Figure 12 shown, the radially outer side of the guide plate 5212 can be sealed with the outer side of the guide groove 5211 to prevent the cleaning liquid from flowing out from the radially outer side of the guide groove 5211; in another embodiment of the present disclosure, it can also be that the guide plate 5212 and the outer wall surface of the dirt receiving part 32 enclose to form the guide groove 521. Further, as Figure 10 shown, in an embodiment of the present disclosure, the guide groove 5211 is arranged on the outer side of the inner wall of the dirt receiving part 32, and the side of the guide plate 5212 facing the inner cavity of the dirt receiving part 32 is configured to form a downward bending part, and the bending part and the inner wall of the dirt receiving part 32 enclose an overflow port 5213 with an opening facing downwards.

[0196] That is, as Figure 10As shown, the diversion groove 5211 is arranged on the radially outer side of the liquid receiving part 32. The radially outer side of the diversion plate 5212 is sealed with the outer side of the diversion groove 5211, which can prevent the cleaning liquid from flowing out from the radially outer side of the diversion groove 5211. A downward bending part is formed on the radially inner side of the diversion plate 5212. The bending part and the inner wall of the liquid receiving part 32 enclose an overflow port 5213 with the opening facing downward and towards the inner cavity of the liquid receiving part 32. In this way, after the liquid level of the cleaning liquid in the diversion groove 5211 exceeds the top end face of the liquid receiving part 32, it will flow to the inner side of the bending part, and then flow out from the overflow port 5213 under the blocking action of the bending part. This can ensure that the cleaning liquid flows downward along the inner wall of the liquid receiving part 32 from the top end of the inner cavity of the liquid receiving part 32. And because the diversion plate 5212 and the diversion groove 5211 are arranged on the outer side rather than the inner side of the inner wall of the liquid receiving part 32, the overflow port 5213 will not protrude from the inner wall of the liquid receiving part 32, avoiding the formation of dead corners below the connection position between the overflow port 5213 and the inner wall of the liquid receiving part 32, so that the cleaning liquid can clean all the inner walls of the liquid receiving part 32 and avoid the occurrence of cleaning dead corners in the liquid receiving part 32.

[0197] As Figure 12 shown, in an embodiment of the present disclosure, at least two spaced support parts 5214 are arranged between the diversion plate 5212 and the top end face of the liquid receiving part 32, and the diversion plate 5212 is at least configured to be supported on the support parts 5214. In this way, the support parts 5214 support the diversion part, ensuring that an overflow port 5213 can be formed between the diversion plate 5212 and the top end face of the liquid receiving part 32, and avoiding the situation where the diversion plate 5212 deforms and part of the overflow port 5213 is blocked, resulting in the abnormal flow of the cleaning liquid.

[0198] It can be understood that the above-mentioned diversion plate 5212 and the cover plate 55 that participated in enclosing the liquid inlet cavity 54 can be fixedly connected or integrally formed, which is not limited here.

[0199] As Figure 10 、 Figure 15 and Figure 16 shown, in an embodiment of the present disclosure, the cleaning base station 10 of the present disclosure further includes a dirt receiving and cleaning member 51. The dirt receiving and cleaning member 51 is arranged at the top of the inner cavity of the dirt receiving part 31 and is configured to enclose a liquid outlet channel 511 with the top wall of the dirt receiving part 31. The cleaning liquid flowing out from the liquid outlet channel 511 is configured to at least flow downward along the inner wall of the dirt receiving part 31.

[0200] In this way, during the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning device 90 is discharged into the sewage tank 3 and then discharged from the sewage pipeline 6, the dirt cleaning member 51 can output cleaning liquid from the top of the dirt containing part 31 to the inner cavity of the dirt containing part 31, so as to clean the inner cavity of the dirt containing part 31, prevent dirt from remaining on the inner cavity of the dirt containing part 31, ensure that the sewage tank 3 of the present disclosure is clean and odorless, and thus effectively improve the user experience. Moreover, since the dirt cleaning member 51 is arranged at the top of the inner cavity of the dirt containing part 31 and forms a liquid outlet channel 511 with the top wall of the dirt containing part 31, the cleaning liquid flowing out of the liquid outlet channel 511 at least flows downward along the top wall of the dirt containing part 31, so as to ensure that the dirt cleaning member 51 can clean the top of the inner cavity of the dirt containing part 31, reduce the cleaning dead corners in the dirt containing part 31, especially eliminate the cleaning dead corners at the top of the dirt containing part 31, and thus reduce the residue of dirt in the inner cavity of the dirt containing part 31.

[0201] As Figure 10 and Figure 15 shown, in an embodiment of the present disclosure, the liquid outlet of the liquid outlet channel 511 is configured to be located in the circumferential direction of the dirt cleaning member 51, and is configured to output cleaning liquid for cleaning the inner wall of the dirt containing cavity in the circumferential direction of the dirt cleaning member 51. In this way, the cleaning liquid can be output outward in the circumferential direction of the dirt cleaning member 51, and since the dirt cleaning member 51 is arranged at the top of the inner cavity of the dirt containing part 31, the cleaning liquid can be output outward in the circumferential direction from the top of the inner cavity of the dirt containing part 31, so as to ensure that the cleaning liquid can clean all circumferential parts of the inner cavity of the dirt containing part 31, avoid the occurrence of cleaning dead corners in the dirt containing part 31, especially at the top of the dirt containing part 31, prevent the residue of dirt in the inner cavity of the dirt containing part 31, and ensure that the dirt containing part 31 of the present disclosure is clean and odorless.

[0202] Specifically, as Figure 10 shown, in an embodiment of the present disclosure, the dirt containing part 31 includes a first part 311 located above and a second part 312 located below. The first part 311 is configured to be docked with the second part 312; the size of the first part 311 is configured to have a gradually expanding structure with an increasing cross-sectional area from top to bottom; the dirt cleaning member 51 is arranged at the central position of the inner cavity of the first part 311 of the dirt containing part 31 and is configured to output cleaning liquid along the circumferential direction of the dirt cleaning member 51. Since the size of the first part 311 of the dirt containing part 31 located above has a gradually expanding structure with an increasing cross-sectional area from top to bottom, when the dirt cleaning member 51 arranged at the central position of the inner cavity of the first part 311 of the dirt containing part 31 outputs cleaning liquid along the circumferential direction of the dirt cleaning member 51, it can ensure that the cleaning liquid at all circumferential parts can flow down along the inner wall of the dirt containing part 31 to clean all circumferential parts of the inner cavity of the dirt containing part 31, and further avoid the occurrence of cleaning dead corners in the dirt containing part 31.

[0203] Specifically, as Figure 10As shown, in one embodiment of the present disclosure, the end face of the dirt-containing cleaning member 51 adjacent to the top wall of the dirt-containing portion 31 is configured to form a liquid outlet channel 511 with the top wall of the dirt-containing portion 31; the circumferential edge of the dirt-containing cleaning member 51 is configured to form the liquid outlet of the liquid outlet channel 511. In this way, after the cleaning liquid flows from the through hole 56 on the top wall of the dirt-containing portion 31 into the liquid outlet channel 511 formed by the end face of the dirt-containing cleaning member 51 adjacent to the top wall of the dirt-containing portion 31 and the top wall of the dirt-containing portion 31, it will be output outward along the circumferential edge of the dirt-containing cleaning member to the inner cavity of the dirt-containing portion 31, and the overall waterway structure is relatively simple.

[0204] Specifically, as Figure 15 and Figure 16 shown, in one embodiment of the present disclosure, at least two partition portions 512 are provided on the end face of the dirt-containing cleaning member 51, and the at least two partition portions 512 are in contact with the top wall of the dirt-containing portion 31; and / or, at least two partition portions 512 are provided on the top wall of the dirt-containing portion 31, and the at least two partition portions 512 are in contact with the end face of the dirt-containing cleaning member 51; the partition portions 512 cause the end face of the dirt-containing cleaning member 51 and the top wall of the dirt-containing portion 31 to enclose the liquid outlet channel 511, and the partition portions 512 are configured to be spaced apart in the circumferential direction of the liquid outlet channel 511.

[0205] That is, the partition portion 512 is provided on one of the end face of the dirt-containing cleaning member 51 or the top wall of the dirt-containing portion 31 and is in contact with the other. Since the partition portions 512 are spaced apart in the circumferential direction of the liquid outlet channel 511, the partition portions 512 cause the end face of the dirt-containing cleaning member 51 and the top wall of the dirt-containing portion 31 to enclose the liquid outlet channel 511 and form a diversion area 5111 in the liquid outlet channel 511, so that the cleaning liquid can flow in the diversion area 5111 formed by the partition portions 512.

[0206] Specifically, as Figure 15 shown, in one embodiment of the present disclosure, the partition portion 512 is configured to extend in the radial direction of the liquid outlet channel 511; the two side walls of the partition portion 512 are configured to intersect in the direction adjacent to the liquid outlet and form the first end of the partition portion 512. Since the partition portion 512 extends in the radial direction of the liquid outlet channel 511, and the two side walls of the partition portion 512 intersect in the direction adjacent to the liquid outlet and form the first end of the partition portion 512, that is, as Figure 15 shown, the partition portion 512 is angular in the direction adjacent to the liquid outlet. When the cleaning liquid coming from the left and right sides of the partition portion 512 flows along the two wall surfaces of the partition portion 512, a confluence area will be generated, and the cleaning liquid will flow outwards in the entire circumference of the dirt-containing cleaning member 51, and there will be no cleaning dead angle due to the existence of the partition portion 512.

[0207] It can be understood that the partition portion 512 extending in the radial direction of the liquid outlet channel 511 means extending from the center of the dirt-containing cleaning member 51 to the periphery. AsFigure 15 As shown, the second end of the partition 512 may be in an arc shape, so that the partition 512 is in a teardrop shape as a whole. The second end of the partition 512 may also be in other shapes, which is not limited here.

[0208] Specifically, such as Figure 15 As shown, in one embodiment of the present disclosure, the first end of the partition 512 is constructed to not exceed the liquid outlet of the liquid outlet channel 511, and the area in the liquid outlet channel 511 between the first end of the partition 512 and the liquid outlet forms a confluence area 5112 connected to the guide area 5111.

[0209] In this way, the cleaning liquid can first flow along the guide area 5111 formed by the partition 512. After flowing out of the guide area 5111, it can flow to the confluence area 5112 located between the first end of the partition 512 and the liquid outlet in the liquid outlet channel 511, thereby merging with the cleaning liquid in the adjacent guide area 5111, ensuring that the cleaning liquid is continuously distributed around the circumference of the dirt-containing cleaning part 51 without omission, and thus no cleaning dead corners are generated.

[0210] like Figure 15 As shown, in one embodiment of the present disclosure, in the radial direction of the dirt-containing cleaning member 51, the end face of the dirt-containing cleaning member 51 includes at least a first inclined surface 515 adjacent to its edge position and configured to extend obliquely downward, and a second inclined surface 516 away from its edge position and configured to extend obliquely upward, the first inclined surface 515 is transitionally connected to the second inclined surface 516; the partition portion 512 is configured to be located within the second inclined surface 516, and the first end of the partition portion 512 does not exceed the second inclined surface 516.

[0211] In this way, as the cleaning liquid flows along the second inclined surface 516, the gap between the end face of the dirt-receiving cleaning member 51 and the inner wall of the dirt-receiving portion 31 can be continuously reduced, and the cleaning liquid will be squeezed. In this way, when the cleaning liquid flows between the guide area 5111 formed by the partition 512, the cleaning liquid will not be interrupted in any circumferential direction. After the cleaning liquid flows to the first inclined surface 515 at the edge of the dirt-receiving cleaning member 51, the first inclined surface 515 extending downwardly and conforming to the contour of the top inner wall of the dirt-receiving portion 31 can ensure that the cleaning liquid can flow toward the inner wall of the dirt-receiving portion 31 to clean the inner wall of the dirt-receiving portion 31. The end face of the dirt-receiving cleaning member 51 can be an arc-shaped curved surface or a straight sloped surface, which is not limited here.

[0212] In one embodiment of the present disclosure, the cleaning base station 10 of the present disclosure further includes an elastic member. The dirt-containing cleaning member 51 is configured to be pre-pressed against the top wall of the dirt-containing portion 31 through the elastic member. The dirt-containing cleaning member 51 is configured to move away from the top wall of the dirt-containing portion 31 when the external force acting on it is greater than a threshold value, and to move towards the top wall of the dirt-containing portion 31 under the action of the elastic member when the external force acting on it is less than the threshold value. In this way, when no cleaning liquid flows out of the through hole 56 or the water pressure of the cleaning liquid is relatively small, the dirt-containing cleaning member 51 can move towards the top wall of the dirt-containing portion 31 under the elastic force of the elastic member, so as to be pressed tightly against the top wall of the dirt-containing portion 31 to block the top wall of the dirt-containing portion 31. And when the water pressure of the cleaning liquid becomes small, the dirt-containing cleaning member 51 can move towards the top wall of the dirt-containing portion 31 under the elastic force of the elastic member, so as to narrow the liquid outlet channel 511, keep the liquid outlet channel 511 from being blocked and maintain a certain liquid outlet pressure during liquid outlet, thereby improving the flushing effect of the dirt-containing cleaning member 51.

[0213] When the water pressure of the cleaning liquid flowing out of the through hole 56 is relatively large and greater than the threshold value, under the action of the water pressure of the cleaning liquid, the dirt-containing cleaning member 51 can overcome the elastic force of the elastic member and move away from the top wall of the dirt-containing portion 31, naturally opening the liquid outlet channel 511, so that the cleaning liquid can be continuously output from all around the circumference of the dirt-containing cleaning member 51, ensuring that the water pressure of the cleaning liquid for cleaning the dirt-containing portion 31 is relatively large, so as to meet the cleaning requirements.

[0214] As Figure 7 and Figure 10 As shown in the figure, in one embodiment of the present disclosure, the sewage discharge tank 3 includes a sewage receiving portion 32 communicating with the inner cavity of the dirt-containing portion 31. The sewage receiving port 321 provided at the top of the sewage receiving portion 32 is configured to be lower than the top of the dirt-containing portion 31; a baffle 33 is provided on one side of the dirt-containing portion 31 adjacent to the sewage receiving portion 32, and the baffle 33 is configured to extend downward from the top wall of the dirt-containing portion 31 to a position adjacent to the sewage receiving port 321. Since a baffle 33 is provided on one side of the dirt-containing portion 31 adjacent to the sewage receiving portion 32, and the baffle 33 extends downward from the top wall of the dirt-containing portion 31 to a position adjacent to the sewage receiving port 321, it is possible to prevent the cleaning liquid output by the dirt-containing cleaning member 51 from flowing to the inner wall of the sewage receiving portion 32, interfering with the cleaning liquid output by the sewage receiving cleaning member 52, and also preventing the cleaning liquid from being splashed outside the sewage receiving port 321.

[0215] As Figure 3 As shown in the figure, in one embodiment of the present disclosure, the cleaning base station 10 of the present disclosure further includes a blockage sensor 8. The blockage sensor 8 is provided at the detection position 81 of the sewage discharge tank 3, and the blockage sensor 8 is configured to be triggered when a sewage discharge blockage occurs at the detection position 81; wherein, the volume of the cleaning base station 10 below the detection position 81 is configured to be greater than 80% of the volume of the sewage bucket 92.

[0216] Specifically, the blockage sensor 8 is usually an optical sensor, including a light emission end and a light reception end. When the liquid flows through the end face of the blockage sensor 8, the light emitted from the light emission end is refracted and cannot be reflected back to the light reception end, thus triggering the detection of the liquid signal.

[0217] Assume that the time required to drain the sewage bucket 92 of the cleaning device 90 when it is full and there is no blockage in the sewage discharge groove 3 is t1. During the t1 time required for this sewage discharge process, the dirt will continuously flow through the blockage sensor 8, and the maximum continuous time for the blockage sensor 8 to sense the liquid signal is t1. When a blockage occurs in the sewage discharge groove 3 and the blockage water level reaches the blockage sensor 8, and the blockage sensor 8 detects the liquid signal, if the continuous time for the liquid level sensor 8 to detect the liquid signal is greater than t1, it can be determined that a sewage discharge blockage has occurred.

[0218] In the existing cleaning base station, the volume below the detection position 81 in the sewage discharge groove 3 is small. When the sewage discharge volume is large, the dirt is likely to accumulate at the detection position 81, but in fact, there is no blockage, so false alarms will occur. During the operation of the cleaning base station 10 of the present disclosure, the floor brush assembly 94 of the cleaning device 90 is placed on the tray 2, the sewage discharge port 93 of the cleaning device 90 will be docked with the sewage receiving port 321 on the sewage discharge groove 3, and the dirt in the sewage bucket 92 will flow into the sewage discharge groove 3. Since the blockage sensor 8 is arranged in the sewage discharge groove 3 and can be triggered when the liquid level of the dirt in the sewage discharge groove 3 reaches the detection position 81, in this way, when a blockage occurs in the cleaning base station 10 of the present disclosure and the liquid level of the dirt in the sewage discharge groove 3 reaches the detection position 81, the blockage sensor 8 can be triggered in time, which is convenient for the cleaning base station 10 of the present disclosure to accelerate sewage discharge, so as to remove the blocked dirt in the sewage discharge pipeline 6 or perform other subsequent steps.

[0219] And since the volume below the detection position 81 in the cleaning base station 10 is greater than 80% of the volume of the sewage bucket 92, even when the sewage discharge volume is large, the dirt is not likely to accumulate at the detection position 81, thus effectively avoiding false alarms.

[0220] Furthermore, in an embodiment of the present disclosure, the volume above the detection position 81 in the sewage discharge groove 3 is configured to be greater than the volume of the sewage bucket 92.

[0221] Among them, after the cleaning device 90 starts to drain sewage, due to the blockage of the cleaning base station 10, the dirt in the sewage discharge tank 3 cannot be smoothly discharged. When the liquid level of the dirt reaches the detection position 81, the blockage sensor 8 can be triggered in time to facilitate the cleaning base station 10 to handle it. After the cleaning device 90 starts to drain sewage, due to the blockage of the cleaning base station 10, the dirt in the sewage discharge tank 3 cannot be smoothly discharged. When the liquid level of the dirt does not reach the detection position 81, the blockage sensor 8 will not be triggered; after the cleaning device 90 drains sewage again, the dirt in the sewage discharge tank 3 continues to accumulate. When the liquid level of the dirt in the sewage discharge tank 3 reaches the detection position 81, the blockage sensor 8 will be triggered, but the sewage discharge process of the cleaning device 90 will not stop, but will continue until the dirt in the sewage bucket 92 is emptied. At this time, since the volume above the detection position 81 in the sewage discharge tank 3 is larger than the volume of the sewage bucket 92, even when the sewage discharge tank 3 just does not reach the detection position 81 and the blockage sensor 8 is not triggered at the end of the first sewage discharge, during the second sewage discharge process, the sewage discharge tank 3 can still accommodate all the dirt in the sewage bucket 92, and the dirt will not overflow from the sewage bucket 92, thus preventing the dirt from overflowing from the sewage discharge tank 3 and polluting the cleaning base station 10, effectively reducing the user's burden and improving the user's experience.

[0222] Specifically, in an embodiment of the present disclosure, the sewage discharge tank 3 includes a dirt-containing part 31 and a dirt-receiving part 32 communicating with the inner cavity of the dirt-containing part 31; the detection position 81 is located in the inner cavity of the dirt-containing part 31; among them, the volume above the detection position 81 includes the part of the dirt-containing part 31 above the detection position 81 and the part of the dirt-receiving part 32 above the detection position 81. It can be understood that the part of the dirt-containing part 31 above the detection position 81 and the part of the dirt-receiving part 32 above the detection position 81 can both be used to temporarily store dirt, so that when the cleaning base station 10 is blocked, the dirt can be prevented from overflowing from the sewage discharge tank 3 and polluting the cleaning base station 10, and the required volume in the sewage discharge tank 3 can be effectively reduced, facilitating the miniaturization of the cleaning base station 10 of the present disclosure.

[0223] Specifically, as Figure 7 shown, in an embodiment of the present disclosure, the top of the dirt-receiving part 32 is configured to form a dirt-receiving port 321 extending outward from the dirt-containing part 31. The opening direction of the dirt-receiving port 321 is configured to face upward and is configured to be docked with the sewage discharge port 93 of the cleaning device 90; the volume above the detection position 81 includes the part of the dirt-containing part 31 and the dirt-receiving part 32 between the detection position 81 and the dirt-receiving port 321. Since the volume above the detection position 81 includes the part of the dirt-containing part 31 and the dirt-receiving part 32 between the detection position 81 and the dirt-receiving port 321, when the cleaning base station 10 is blocked, the dirt can be prevented from overflowing from the dirt-receiving port 321 of the dirt-receiving part 32 and polluting the cleaning base station 10.

[0224] As Figure 7 shown, in an embodiment of the present disclosure, the top end surface of the dirt receiving port 321 is configured to be lower than the top of the dirt containing portion 31. When the top end surface of the dirt receiving port 321 is lower than the top of the dirt containing portion 31, the detection position 81 can be set below the top end surface of the dirt receiving port 321, and in a part where the volume meets the above requirements, ensuring that the blockage sensor 8 can be normally triggered for blockage conditions.

[0225] As Figure 4 and Figure 7 shown, in an embodiment of the present disclosure, the dirt receiving portion 32 is connected to one side of the dirt containing portion 31. The dirt receiving portion 32 has a sewage discharge surface 325 extending to communicate with the inner cavity of the dirt containing portion 31. At least part of the dirt flowing out from the sewage discharge port 93 is configured to flow from the sewage discharge surface 325 to the inner cavity of the dirt containing portion 31; the detection position 81 is configured to be set on the side of the dirt containing portion 31 away from the sewage discharge surface 325.

[0226] In this way, during the working process of the cleaning base station 10 of the present disclosure, the sewage discharge surface 325 of the dirt receiving portion 32 can receive the dirt discharged from the sewage discharge port 93 of the cleaning device 90 and divert the dirt discharged from the cleaning device 90 to the inner cavity of the dirt containing portion 31. Since the detection position 81 is set on the side of the dirt containing portion 31 away from the sewage discharge surface 325, the dirt is not likely to impact the blockage sensor 8 at the detection position 81 during the flowing process along the sewage discharge surface 325, reducing the probability of false alarms of the blockage sensor 8.

[0227] Further, in an embodiment of the present disclosure, the detection position 81 is configured to be not lower than the bottom end of the sewage discharge surface 325. When the dirt flows along the sewage discharge surface 325 of the dirt receiving portion 32 into the inner cavity of the dirt containing portion 31, since the detection position 81 is not lower than the bottom end of the sewage discharge surface 325, even if the flowing speed is relatively fast during the process of the dirt flowing into the inner cavity of the dirt containing portion 31, it will not directly impact the blockage sensor 8 at the detection position 81, thereby effectively avoiding false alarms of the blockage sensor 8.

[0228] In an embodiment of the present disclosure, the volume of the sewage discharge tank 3 above the detection position 81 is configured to be larger than the volume of the sewage discharge tank 3 below the detection position 81. Since the volume of the sewage discharge tank 3 above the detection position 8 is configured to be larger than the volume of the sewage discharge tank 3 below the detection position 81, it can ensure that the volume of the sewage discharge tank 3 above the detection position 81 can meet the requirements, and on the premise that the dirt overflows from the sewage discharge tank 3 to pollute the cleaning base station 10, the required volume in the sewage discharge tank 3 is reduced, facilitating the miniaturization of the cleaning base station 10 of the present disclosure.

[0229] In another embodiment of the present disclosure, the volume below the detection position 81 in the cleaning base station 10 is 0.8 to 1.2 times the volume of the sewage bucket 92. Since the volume below the detection position 81 in the sewage discharge groove 3 is 0.8 to 1.2 times the volume of the sewage bucket 92, and since it takes a certain amount of time for the cleaning base station 10 of the present disclosure to discharge dirt, therefore, the part below the detection position 81 in the sewage discharge groove 3 can temporarily store dirt during the process of the cleaning base station 10 of the present disclosure discharging dirt. After ensuring that the dirt of the cleaning device 90 is quickly discharged into the sewage discharge groove 3, when the cleaning base station 10 is not blocked, the liquid level of the dirt will not reach the detection position 81, and thus the blockage sensor 8 will not be triggered, preventing the liquid level of the dirt from reaching the detection position 81 during each sewage discharge process, resulting in false alarms of the blockage sensor 8. It can be understood that the volume below the detection position 81 in the cleaning base station 10 includes not only the part of the sewage discharge groove 3 below the detection position 81, but also the volume in the sewage discharge pipe 6.

[0230] In one embodiment of the present disclosure, the control unit of the present disclosure is configured to send an alarm message based on the electrical signal triggered by the blockage sensor 8. In this way, when the blockage sensor 8 is triggered, the control unit can send an alarm message in a timely manner, thereby notifying the user to perform maintenance or other work.

[0231] In one embodiment of the present disclosure, if the blockage sensor 8 detects a blockage, the self-cleaning is cancelled, and a prompt and charging are performed. In another embodiment set of the present disclosure, if a blockage occurs, the jet component can first work for a period of time (for example, 3 s. During these 3 s, it can work in the manner of the original water flow size, or in the manner of increasing the water flow, so as to increase the kinetic energy of flushing dirt). This period of time is related to the volume (900 ml) of the sewage discharge groove above the blockage sensor and the flow rate (8 L / min to 15 L / min) of the jet component, and water cannot overflow. Wait for a period of time (such as 5 s. It takes a certain amount of time for the blocked dirt to be discharged). If the sewage discharge groove is still blocked, the self-cleaning is cancelled, and a prompt and charging are performed.

[0232] It can be understood that when the aforementioned jet assembly 7 is provided in the cleaning base station 10 of the present disclosure, while the cleaning base station 10 of the present disclosure sends an alarm message, the jet assembly 7 is controlled to work for a period of time to accelerate the flow of dirt in the sewage discharge pipe 6, so as to wash away the blocked dirt in the sewage discharge pipe 6. However, in the case where the blockage is relatively serious and cannot be washed away, the user can only manually clean it.

[0233] In one embodiment of the present disclosure, a sewage receiving port 321 for docking with a sewage discharge port 93 of a cleaning device 90 is provided on the sewage discharge tank 3; and the sewage discharge tank 3 is configured to rotate between a first position and a second position. When the sewage receiving port 321 is in the first position, it is located on the front side of the tray 2, and when it is in the second position, the sewage receiving port 321 is located inside the base 1. In this way, when the cleaning device 90 needs to be docked with the cleaning base station 10 for sewage discharge, the sewage discharge tank 3 can rotate to the first position, the sewage discharge port 93 of the cleaning device 90 can be docked with the sewage receiving port 321 of the sewage discharge tank 3, and the dirt in the cleaning device 90 can be discharged into the cleaning base station 10 through the sewage receiving port 321; when sewage discharge is not required, the sewage discharge tank 3 can rotate to the second position, so that the sewage receiving port 321 is received inside the base 1, thereby hiding the sewage receiving port 321 and preventing the sewage discharge tank 3 from emitting an odor, effectively improving the user experience. Specifically, a structure such as a motor or other mechanical transmission device can be used to control the rotation of the sewage discharge tank 3. The specific principle can refer to other existing technologies and will not be elaborated here. In another embodiment, the rotation of the sewage discharge tank 3 can also be achieved by the docking of the cleaning device 90 and the cleaning base station 10. Specifically, a first trigger member can be provided on the base station 10, and the first trigger member has an initial state and a first state. When the cleaning device 90 is docked with the base station 10, the cleaning device 90 abuts against the first trigger member, causing the first trigger member to change from the initial state to the first state, and then driving the sewage discharge tank 3 to rotate to the first position. When the cleaning device 90 is removed from the base station 10, the first trigger member returns from the first state to the initial state, driving the sewage discharge tank 3 to rotate to the second position.

[0234] In one embodiment of the present disclosure, a sewage receiving port 321 for docking with a sewage discharge port 93 of a cleaning device 90 is provided on the sewage discharge tank 3; and a partition is provided on the sewage receiving port 321, and the partition is configured to open or close the sewage receiving port 321. Specifically, the partition can rotate or translate relative to the sewage receiving port 321 to open or close the sewage receiving port 321, and the specific principle is not limited.

[0235] When the cleaning device 90 needs to be docked with the cleaning base station 10 for sewage discharge, the partition can be opened, and the sewage outlet 93 of the cleaning device 90 can be docked with the sewage receiving port 321 of the sewage trough 3. The dirt in the cleaning device 90 can be discharged into the cleaning base station 10 through the sewage receiving port 321. When sewage discharge is not required, the sewage receiving port 321 can be closed by using the partition, thereby hiding the sewage receiving port 321 and preventing the sewage trough 3 from emitting odors, effectively improving the user experience. Specifically, a structure such as a motor or other mechanical transmission device can be used to control the movement of the partition. The specific principle can refer to other existing technologies and will not be elaborated here. In another embodiment, the movement of the partition can also be achieved through the docking of the cleaning device 90 and the cleaning base station 10. Specifically, a second trigger member can be provided on the base station 10. The second trigger member has an initial state and a second state. When the cleaning device 90 is docked with the base station 10, the cleaning device 90 abuts against the second trigger member, causing the second trigger member to change from the initial state to the second state, thereby driving the partition to move to open the sewage receiving port 321. When the cleaning device 90 is removed from the base station 10, the second trigger member returns from the second state to the initial state, driving the partition to move to close the sewage receiving port 321.

[0236] As Figure 10 shown, in an embodiment of the present disclosure, the sewage trough 3 includes a sewage receiving part 31. The sewage receiving part 31 includes a gradually expanding part with a gradually increasing cross-sectional area from top to bottom and a gradually shrinking part with a gradually decreasing cross-sectional area from top to bottom. The gradually expanding part is docked above the gradually shrinking part. The detection position 81 is located at the docking position of the bottom end of the gradually expanding part and the gradually shrinking part. That is, the detection position 81 is located at the docking position of the bottom end of the first part 311 and the shrinking part, which can increase the volume below the detection position 81 when blockage occurs and reduce the probability of false alarms when the drainage speed is slow. At the same time, since the docking position of the bottom end of the gradually expanding part and the gradually shrinking part of the sewage receiving part 31 is very obvious, it is convenient for the staff to install the blockage sensor 8 without having to locate the detection position 81 in advance before installation.

[0237] As Figures 1 to 3 shown, the present disclosure also provides a cleaning system, which includes a cleaning device 90 and a cleaning base station 10. The cleaning device 90 includes a body 91 and a sewage outlet 93 provided on the body 91.

[0238] Application scenario

[0239] The present disclosure provides a cleaning base station 10 for cooperating with a cleaning device 90 to perform cleaning work. The cleaning base station 10 includes a base 1, a tray 2, and a sewage discharge tank 3; the base 1 is configured to extend in the height direction and is used to install various functional components required for the cleaning base station 10 such as the sewage discharge tank 3. The tray 2 is disposed at the bottom of the base 1 and extends forward horizontally relative to the base 1, and the side opposite to the front side is denoted as the rear side. The sewage discharge tank 3 includes a sewage receiving portion 31 located inside the cleaning base station 10 and a sewage bearing portion 32 communicating with the inner cavity of the sewage receiving portion 31; the sewage bearing portion 32 is located at the front side of the sewage receiving portion 31 and is configured to be connected to the side wall of the sewage receiving portion 31 to enclose a containing cavity with the sewage receiving portion 31.

[0240] During the working process of the cleaning base station 10 of the present disclosure, the cleaning device 90 is placed on the tray 2, the sewage discharge port 93 of the cleaning device 90 is located above the sewage bearing portion 32, and the dirt discharged by the cleaning device 90 can be discharged into the sewage discharge tank 3. Among them, the sewage bearing portion 32 is located at the front side of the sewage receiving portion 31 and is connected to the side wall of the sewage receiving portion 31, mainly used to receive the dirt discharged by the cleaning device 90 and guide the dirt discharged by the cleaning device 90 into the sewage receiving portion 31; the sewage receiving portion 31 is disposed inside the base 1, mainly used to temporarily store dirt and guide the dirt discharged by the cleaning device 90 into the sewage pipeline 6 so that the dirt is discharged to the outside.

[0241] Since the sewage bearing portion 32 is located at the front side of the sewage receiving portion 31 and is connected to the side wall of the sewage receiving portion 31, protruding forward from the base 1, and the sewage receiving portion 31 is located inside the base 1, the layout of the cleaning base station 10 of the present disclosure can be effectively optimized, space can be saved, which is beneficial to the miniaturization of the cleaning base station 10. And, when the sewage discharge tank 3 is blocked, the sewage bearing portion 32 and the sewage receiving portion 31 can jointly accommodate dirt to prevent the dirt from overflowing from the sewage discharge tank 3. Compared with the existing cleaning base station 10, the overall volume of the sewage discharge tank 3 of the cleaning base station 10 of the present disclosure is larger and the occupied space is smaller, effectively improving the user experience.

[0242] Application Scenario 2

[0243] The present disclosure provides a cleaning base station 10, which is used to cooperate with a cleaning device 90 for cleaning work. Specifically, the cleaning base station 10 includes a base 1, a tray 2, a sewage discharge tank 3, and a sewage discharge pipe 6; the base 1 is configured to extend in the height direction; the tray 2 is located at the bottom of the base 1 and is configured to extend in the horizontal direction. A brush roller groove 21 is provided on the tray 2 for accommodating the brush roller of the cleaning device 90, and the axis direction of the brush roller groove 21 is taken as the first direction; the sewage discharge tank 3 is arranged in the cleaning base station 10; the sewage discharge pipe 6 is configured to communicate with the bottom of the sewage discharge tank 3; the sewage discharge pipe 6 at least has a sewage discharge section 62 extending in the lateral direction and a connection section 61 connecting the sewage discharge section 62 and the bottom of the sewage discharge tank 3. One end of the connection section 61 is configured to extend towards the bottom of the sewage discharge tank 3 to communicate with the bottom of the sewage discharge tank 3, and the other end is configured to extend towards the sewage discharge section 62 to communicate with the sewage discharge section 62; the sewage discharge section 62 extends along the first direction.

[0244] During the working process of the cleaning base station 10 of the present disclosure, the floor brush assembly 94 of the cleaning device 90 is placed on the tray 2, and the sewage discharge port 93 of the cleaning device 90 discharges dirt into the sewage discharge tank 3 in the base 1. The dirt will flow into the connection section 61 of the sewage discharge pipe 6 from the bottom of the sewage discharge tank 3, and then flow along the sewage discharge section 62. Since the sewage discharge section 62 extends along the first direction, the overall width of the cleaning base station 10 can be effectively utilized to arrange the sewage discharge section 62, thereby reducing the length of the overall cleaning base station 10 of the present disclosure in the second direction. Moreover, since the sewage discharge section 62 extends along the first direction, the dirt only needs to turn once through the connection section 61 during the process of flowing to the sewage discharge section 62, and the extending direction of the sewage discharge section 62 is the same as that of the external extension pipe connected to the sewage discharge outlet of the base station, so that the kinetic energy loss of the dirt during the sewage discharge process can be effectively reduced, and the sewage discharge is smoother.

[0245] Application Scenario 3

[0246] The present disclosure provides a cleaning base station 10, including a base 1, a tray 2, and a sewage discharge tank 3. The base 1 is configured to extend in the height direction; the tray 2 is located at the bottom of the base 1 and is configured to extend in the horizontal direction; one side of the base 1 where the tray 2 is provided is denoted as the front side, and the side opposite thereto is denoted as the rear side; the sewage discharge tank 3 includes a sewage receiving part 31 located inside the base station and a sewage supporting part 32 communicating with the inner cavity of the sewage receiving part 31; the sewage supporting part 32 is configured to have a sewage receiving port 321 for docking with the sewage discharge port 93 of the cleaning device 90; the sewage supporting part 32 has a sewage discharging surface 325, and at least part of the dirt flowing in from the sewage receiving port 321 is configured to be guided from the sewage discharging surface 325 into the inner cavity of the sewage receiving part 31; the area on the sewage discharging surface 325 corresponding to the sewage discharge port 93 is configured to be a flat straight surface or a continuous smooth curved surface.

[0247] During the operation of the cleaning base station 10 of the present disclosure, the cleaning device 90 is placed on the tray 2. The sewage outlet 93 of the cleaning device 90 is located above the sewage receiving part 32, and the dirt discharged by the cleaning device 90 can be discharged into the sewage tank 3. Among them, the sewage receiving surface 325 of the sewage receiving part 32 can receive the dirt discharged from the sewage outlet 93 of the cleaning device 90 and guide the dirt discharged by the cleaning device 90 into the inner cavity of the dirt containing part 31, that is, at least part of the dirt flowing out of the sewage outlet 93 can flow from the sewage receiving surface 325 to the inner cavity of the dirt containing part 31; the dirt containing part 31 is arranged in the base 1 and is mainly used for temporarily storing dirt and guiding the dirt discharged by the cleaning device 90 into the sewage pipe 6 so that the dirt can be discharged to the outside. Specifically, since the area corresponding to the sewage outlet 93 on the sewage receiving surface 325 is configured to be a flat straight surface or a continuous smooth curved surface, when the dirt falls from the sewage receiving port 321 onto the sewage receiving surface 325, it will flow smoothly downward, ensuring that the dirt continues to flow toward the sewage pipe 6 with greater kinetic energy, and can also prevent the dirt from splashing out of the sewage receiving port 321 when it falls onto the sewage receiving surface 325 and onto the base 1 or the tray 2 of the cleaning base station 10, eliminating the need for the user to perform secondary cleaning on the cleaning base station 10, effectively reducing the user's burden of use, and improving the user's experience of use.

[0248] Application Scenario 4

[0249] The present disclosure provides a cleaning base station 10, which is used to cooperate with a cleaning device 90 for cleaning work. Specifically, the cleaning base station 10 includes a base 1, a sewage tank 3 and a self-cleaning component 5; the base 1 is configured to extend in the height direction; the sewage tank 3 includes a dirt containing part 31 located in the base 1 and a sewage receiving part 32 communicated with the inner cavity of the dirt containing part 31, and the sewage receiving part 32 is configured to be connected to the side wall of the dirt containing part 31; the self-cleaning component 5 is located at the top of the sewage tank 3 and is configured to output cleaning liquid from the top of the dirt containing part 31 into the inner cavity of the dirt containing part 31, and output cleaning liquid from the top of the dirt containing part 31 to the top of the sewage receiving part 32 and the inner cavity of the sewage receiving part 32.

[0250] During the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning device 90 is discharged into the sewage tank 3 and then discharged from the sewage pipeline 6, the self-cleaning assembly 5 can output cleaning liquid from the top of the dirt-containing part 31 to the inner cavity of the dirt-containing part 31, and output cleaning liquid from the top of the dirt-containing part 31 to the top and the inner cavity of the dirt-receiving part 32, so as to clean the inner cavities of the dirt-containing part 31 and the dirt-receiving part 32, prevent dirt from remaining on the inner cavities of the dirt-containing part 31 and the dirt-receiving part 32, ensure that the sewage tank 3 of the present disclosure is clean and odorless, and thus effectively improve the user experience. Moreover, since the self-cleaning assembly 5 can output cleaning liquid from the top of the dirt-containing part 31 to the inner cavity of the dirt-containing part 31 and the inner cavity of the dirt-receiving part 32, there is no need to separately provide a cleaning mechanism for the dirt-containing part 31 and the dirt-receiving part 32, which can effectively simplify the waterway structure of the cleaning base station 10 of the present disclosure and promote the miniaturization of the cleaning base station 10 of the present disclosure.

[0251] Application Scenario 5

[0252] The present disclosure provides a cleaning base station 10, which is used to cooperate with a cleaning device 90 for cleaning work. Specifically, the cleaning base station 10 includes a base 1, a sewage tank 3 and a dirt-receiving and cleaning member 52; the base 1 is configured to extend in the height direction; the sewage tank 3 includes a dirt-receiving part 32 having a dirt-receiving port 321, and the dirt-receiving port 321 is configured to be used for docking with the sewage outlet 93 of the cleaning device 90; the dirt-receiving and cleaning member 52 is disposed around the dirt-receiving port 321 and is configured to output cleaning liquid to the inner cavity of the dirt-receiving part 32; the dirt-receiving and cleaning member 52 includes a liquid inlet section 522 and a liquid discharge section 521, the liquid discharge section 521 is configured to communicate with the liquid inlet section 522 and is disposed at a position lower than the liquid inlet section 522; the cleaning liquid is configured to flow from the liquid inlet section 522 to the liquid discharge section 521 and is configured to flow from the liquid discharge section 521 to the inner cavity of the dirt-receiving part 32.

[0253] In this way, during the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged from the sewage outlet 93 of the cleaning device 90 is discharged into the sewage tank 3 from the dirt-receiving port 321 of the dirt-receiving part 32 and then discharged from the sewage pipeline 6, the dirt-receiving and cleaning member 52 can output cleaning liquid to the inner cavity of the dirt-receiving part 32 to clean the inner cavity of the dirt-receiving part 32. Since the dirt-receiving and cleaning member 52 is disposed around the dirt-receiving port 321, when the dirt-receiving and cleaning member 52 outputs cleaning liquid, it can clean the inner cavity of the dirt-receiving part 32, prevent dirt from remaining on the inner cavity of the dirt-receiving part 32, ensure that the dirt-receiving part 32 of the present disclosure is clean and odorless, and thus effectively improve the user experience.

[0254] Moreover, since the dirt-receiving and cleaning member 52 includes a liquid inlet section 522 and a liquid discharge section 521, the liquid discharge section 521 communicates with the liquid inlet section 522 and is arranged at a position lower than the liquid inlet section 522. In this way, the cleaning liquid can naturally flow from the liquid inlet section 522 to the liquid discharge section 521 under the action of its own gravity, and then flow to the inner cavity of the dirt-receiving part 32 through the liquid discharge section 521, without the need for an external power source to provide power for the flow of the cleaning liquid. Thus, the power source required for the dirt-receiving and cleaning member 52 can be omitted, effectively simplifying the waterway structure of the cleaning base station 10 of the present disclosure and promoting the miniaturization of the cleaning base station 10 of the present disclosure.

[0255] Application Scenario 6

[0256] The present disclosure provides a cleaning base station 10, which is used to cooperate with a cleaning device 90 for cleaning work. Specifically, the cleaning base station 10 includes a base 1, a sewage draining tank 3, and a dirt-receiving and cleaning member 51; the base 1 is configured to extend in the height direction; the sewage draining tank 3 includes a dirt-receiving part 31 located inside the base 1; the dirt-receiving and cleaning member 51 is arranged at the top of the inner cavity of the dirt-receiving part 31 and is configured to enclose a liquid outlet channel 511 with the top wall of the dirt-receiving part 31, and the cleaning liquid flowing out of the liquid outlet channel 511 is configured to flow at least downward along the inner wall of the dirt-receiving part 31.

[0257] In this way, during the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning device 90 is discharged into the sewage draining tank 3 and discharged from the sewage draining pipe 6, the dirt-receiving and cleaning member 51 can output cleaning liquid from the top of the dirt-receiving part 31 to the inner cavity of the dirt-receiving part 31, thereby cleaning the inner cavity of the dirt-receiving part 31, preventing dirt from remaining on the inner cavity of the dirt-receiving part 31, ensuring that the sewage draining tank 3 of the present disclosure is clean and odorless, and effectively improving the user experience.

[0258] Moreover, since the dirt-receiving and cleaning member 51 is arranged at the top of the inner cavity of the dirt-receiving part 31 and encloses a liquid outlet channel 511 with the top wall of the dirt-receiving part 31, the cleaning liquid flowing out of the liquid outlet channel 511 flows at least downward along the inner wall of the dirt-receiving part 31, thereby ensuring that the dirt-receiving and cleaning member 51 can clean the top of the inner cavity of the dirt-receiving part 31, reducing the cleaning dead corners in the dirt-receiving part 31, and thus reducing the dirt residue in the inner cavity of the dirt-receiving part 31.

[0259] Application Scenario 7

[0260] The present disclosure provides a cleaning base station 10 configured to dock with a cleaning device 90, and includes a base 1, a sewage discharge tank 3, and a blockage sensor 8. The base 1 is configured to extend in the height direction; a sewage receiving port 321 for docking with a sewage discharge port 93 of the cleaning device 90 is provided on the sewage discharge tank 3; the blockage sensor 8 is disposed at a detection position 81 of the sewage discharge tank 3, and the blockage sensor 8 is configured to be triggered when a sewage blockage occurs at the detection position 81; wherein, the volume inside the base station below the detection position 81 is configured to be greater than 80% of the volume of the sewage bucket 92 of the cleaning device 90.

[0261] During the operation of the cleaning base station 10 of the present disclosure, the floor brush assembly 94 of the cleaning device 90 is placed on the tray 2, the sewage discharge port 93 of the cleaning device 90 will be docked with the sewage receiving port 321 on the sewage discharge tank 3, and the dirt in the sewage bucket 92 will flow into the sewage discharge tank 3. Since the blockage sensor 8 is disposed in the sewage discharge tank 3 and can be triggered when the liquid level of the dirt in the sewage discharge tank 3 reaches the detection position 81, in this way, when the cleaning base station 10 of the present disclosure is blocked and the liquid level of the dirt in the sewage discharge tank 3 reaches the detection position 81, the blockage sensor 8 can be triggered in time, which is convenient for the cleaning base station 10 of the present disclosure to accelerate sewage discharge, so as to remove the blocked dirt in the sewage discharge pipe 6 or perform other subsequent steps.

[0262] And since the volume inside the cleaning base station 10 below the detection position 81 is greater than 80% of the volume of the sewage bucket 92, even when the sewage discharge volume is large, the dirt is not easily accumulated at the detection position 81, so that false alarms can be effectively avoided.

[0263] The above has described the embodiments of the present disclosure. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other ordinary technical personnel in the technical field to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
