Description

Technical Field

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

[0002] Environmental sanitation is a crucial factor affecting the quality of life. Consequently, as people's expectations for quality of life continue to rise, so too do their demands for environmental sanitation. Consequently, a wide range of floor cleaning equipment has emerged, including vacuum cleaners, sweepers, and floor scrubbers. A floor scrubber is a cleaning machine that cleans the floor while simultaneously sucking up wastewater and removing it from the site.

[0003] Existing floor scrubbers are generally provided with a solution bucket for storing cleaning solution and a sewage bucket for collecting sewage after cleaning. In order to pour out the sewage in the sewage bucket, the user needs to personally remove the bucket cover of the sewage bucket and then discharge the sewage through the open upper end of the sewage bucket. This operation is 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 appeared on the market. The floor scrubber can discharge the sewage in the internal sewage bucket by cooperating with the cleaning base station. Some cleaning base stations can also clean cleaning parts such as rags of the floor scrubber.

[0005] However, existing cleaning base stations require users to manually clean the sewage trough, which greatly affects the user experience. Utility Model Content

Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints, but also several sub-ranges contained therein.

[0053] The present disclosure provides a cleaning base station, which is used to perform cleaning work in conjunction with cleaning equipment. Specifically, the cleaning base station includes a base, a drain trough and a self-cleaning component; the base is constructed to extend in the height direction; the drain trough includes a dirt storage part located in the base and a dirt receiving part connected to the inner cavity of the dirt storage part, and the dirt receiving part is constructed to be connected to the side wall of the dirt storage part; the self-cleaning component is located at the top of the drain trough, and the self-cleaning component is constructed to output cleaning liquid from the top of the dirt storage part to the inner cavity of the dirt storage part, and to output cleaning liquid from the top of the dirt storage part to the top of the dirt receiving part and the inner cavity of the dirt receiving part.

[0054] During the operation of the cleaning base station disclosed herein, the dirt discharged by the cleaning equipment is discharged into the drain trough and then discharged from the drain pipe. The self-cleaning component can output cleaning liquid from the top of the dirt holding part to the inner cavity of the dirt holding part, and output cleaning liquid from the top of the dirt holding part to the top of the dirt receiving part and the inner cavity of the dirt receiving part, thereby cleaning the dirt holding part and the inner cavity of the dirt receiving part, preventing dirt from remaining on the dirt holding part and the inner cavity of the dirt receiving part, and ensuring that the drain trough disclosed herein is clean and odorless, thereby effectively improving the user experience. Moreover, since the self-cleaning component can output cleaning liquid from the top of the dirt holding part to the inner cavity of the dirt holding part and the inner cavity of the dirt receiving part, there is no need to set up a cleaning mechanism for the dirt holding part and the dirt receiving part separately, which can effectively simplify the waterway structure of the cleaning base station disclosed herein and promote the miniaturization of the cleaning base station disclosed herein.

[0055] For ease of understanding, refer to Figures 1 to 21 , the specific structure and working principle of the cleaning base station 10 of the present disclosure are described in detail with reference to an embodiment. It should be noted that the present disclosure also provides a cleaning base station 10. To keep the text concise, this article will introduce the cleaning system together with the cleaning base station 10.

[0056] like Figures 1 to 6 As shown, the present disclosure provides a cleaning base station 10, which is used to perform cleaning work in conjunction with a cleaning device 90.

[0057] like Figure 1 and Figure 2 As 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 fluid, etc., which will not be repeated here.

[0058] Specifically, such as Figure 1 and Figure 2 As shown, the cleaning device 90 comprises at least a body 91 and a sewage bucket 92. It is understood that the cleaning device 90 may further comprise a floor brush assembly 94 and a cleaning liquid bucket. The body 91 serves as a carrier for mounting various functional components required by the cleaning device 90.

[0059] The floor brush assembly 94 is arranged at the bottom end of the machine body 91 and is used to clean work surfaces such as the floor, carpet or furniture surface; a rotating shaft can be set between the floor brush assembly 94 and the machine body 91, and the machine body 91 can rotate relative to the floor brush assembly 94 through the rotating shaft. When the machine body 91 is rotated 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 machine body 91 is rotated 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 shown in FIG. Figure 1 、 Figure 2 As shown, the cleaning device 90 can be placed on the cleaning base station 10. When cleaning a work surface, the floor brush assembly 94 remains in contact with the work surface. The floor brush assembly 94 can 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 away stains on the work surface. As shown in the figure, a sewage suction pipe is installed within the portion where the body 91 connects to the floor brush assembly 94. The bottom end of the sewage suction pipe is connected to the sewage suction port provided on the floor brush assembly 94.

[0060] The wastewater bucket 92 is used to hold dirt sucked from the work surface. This dirt can be wastewater generated during cleaning or various types of garbage sucked from the work surface. The bottom of the wastewater bucket 92 is provided with a wastewater outlet 93 and a wastewater inlet. The wastewater outlet 93 of the wastewater bucket 92 is used to connect to the cleaning base station 10, thereby discharging the dirt in the interior of the wastewater bucket 92 into the cleaning base station 10.

[0061] Specifically, such as Figures 1 to 6 As shown, the cleaning base station 10 includes a base 1, a tray 2 and a drainage chute 3; the base 1 is constructed to extend in the height direction and is used to install various functional elements required for the cleaning base station 10, such as the drainage chute 3.

[0062] Tray 2 is disposed at the bottom of base 1 and extends horizontally forward relative to base 1. The side opposite the front is designated as the rear side. Tray 2 is primarily used to support the floor brush assembly 94 of cleaning base station 10 when cleaning device 90 docks with cleaning base station 10 for waste removal. It can also be used to clean the floor brush assembly 94 of cleaning device 90 or charge cleaning base station 10. In other words, it can be understood that the floor brush assembly 94 is located on tray 2 during waste removal.

[0063] The sewage trough 3 includes a sewage receiving portion 31 located in the cleaning base station 10 and a sewage receiving portion 32 connected to the inner cavity of the sewage receiving portion 31; the sewage receiving portion 32 is located on the front side of the sewage receiving portion 31 and is constructed to be connected to the side wall of the sewage receiving portion 31 to enclose a receiving cavity with the sewage receiving portion 31.

[0064] It can be understood that the cleaning base station 10 disclosed in the present invention is a cleaning base station that only uses gravity to discharge sewage; among the existing cleaning base stations, there are cleaning base stations equipped with a sewage suction motor. When the dirt in the recycling bucket of this type of cleaning base station needs to be discharged, the sewage suction motor is turned on to suck the dirt in the recycling bucket into the base station through negative pressure. In this type of cleaning base station, the sewage trough only needs to be set as a holding box, which is different from the structural principle of the cleaning base station that uses gravity to discharge sewage.

[0065] During operation of the cleaning base station 10 of the present disclosure, the cleaning device 90 is placed on the tray 2, and the sewage outlet 93 of the cleaning device 90 is located above the sewage receiving portion 32, and the sewage discharged by the cleaning device 90 can be discharged into the sewage trough 3. The sewage receiving 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. It is mainly used to receive the sewage discharged by the cleaning device 90 and guide the sewage discharged by the cleaning device 90 into the sewage receiving portion 31; the sewage receiving portion 31 is set in the base 1, mainly used to temporarily store sewage and guide the sewage discharged by the cleaning device 90 into the sewage pipe 6 so that the sewage is discharged to the outside.

[0066] Since the dirt receiving portion 32 is located at the front side of the dirt receiving portion 31 and is connected to the side wall of the dirt receiving portion 31, protruding from the base 1 to the front side, the dirt receiving portion 32 docked 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, and 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 form the cavity of the base 1, and the dirt receiving portion 32 is located outside the front wall surface 11 of the base 1), and the dirt receiving portion 31 is located in the cavity of the base 1 (the dirt receiving portion 31 is located inside the front wall surface 11 of the base 1). The dirt receiving portion 32 basically does not occupy the inner 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 receiving portion 31 in the cavity of the base 1, effectively optimizing the layout of the cleaning base station 10 disclosed in the present invention, saving space, and being conducive to the miniaturization of the cleaning base station 10. Furthermore, when the drainage trough 3 is clogged, the dirt receiving portion 32 and the dirt receiving portion 31 can jointly contain the dirt to prevent the dirt from overflowing from the drainage trough 3. Compared with existing cleaning base stations, the drainage trough 3 of the cleaning base station 10 disclosed herein has a larger overall volume and occupies less space, effectively improving the user experience.

[0067] like Figure 6As shown, in one embodiment of the present disclosure, a roller brush groove 21 is provided on the tray 2, with 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. The first direction and the second direction are both located in the horizontal plane, and the dirt holding portion 31 is constructed so that its size in the first direction is greater than its size in the second direction. Since the tray of the cleaning base station needs to accommodate the roller brush of the floor brush assembly of the cleaning equipment, 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 size of the dirt holding portion 31 in the first direction is greater than its size in the second direction, this design of the dirt holding portion 31 can make full use of the space of the base station in the axial direction of the roller brush groove. On the premise of ensuring the volume of the dirt holding portion 31 of the present disclosure, the thickness of the dirt holding portion 31 and the base 1 on which it is located is effectively reduced, which is conducive to the miniaturization of the base station, increases user acceptance and favorability, and thus facilitates the layout of the cleaning base station 10 of the present disclosure.

[0068] like Figure 3 As shown, in one embodiment of the present disclosure, the dirt receiving portion 32 is lower than the dirt containing portion 31 , which can facilitate cleaning of various locations in the drain trough 3 and prevent the occurrence of cleaning dead corners in the drain trough 3 .

[0069] It can be understood that in the sewage trough 3 disclosed in the present invention, the sewage receiving part 32 and the sewage containing part 31 can be integrally formed and only distinguished as two parts with different functions. The sewage receiving part 32 and the sewage containing part 31 can also be processed separately and then fixedly connected together. The specific processing technology is not limited here.

[0070] In order 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. The control unit can be connected to various components on the cleaning base station 10 of the present disclosure through signals to control their operating states.

[0071] Specifically, such as Figures 7 to 10 As shown, in one embodiment of the present disclosure, the top of the dirt-receiving portion 32 is constructed to extend from the dirt-receiving portion 31 to the front side to form a dirt-receiving port 321; the opening direction of the dirt-receiving port 321 is constructed to face upward, and is constructed to be docked with the dirt outlet 93 of the cleaning device 90. Since the top of the dirt-receiving portion 32 extends from the dirt-receiving portion 31 to the front side to form the dirt-receiving port 321 with the opening facing upward, during the operation of the cleaning base station 10 of the present disclosure, when the cleaning device 90 is placed on the tray 2, the dirt outlet 93 of the cleaning device 90 can be located above the dirt-receiving portion 32 and docked 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 portion 32, and then flow into the dirt-receiving portion 31. Figure 9 and Figure 10As shown, in one embodiment of the present disclosure, the end surface of the sewage receiving port 321 is constructed to extend obliquely downward from the position where it is connected to the sewage receiving portion 31, so that the end surface of the sewage receiving port 321 is constructed to be lower in height than the position where the sewage receiving port 321 is connected to the sewage receiving portion 31. In this way, when the front side of the sewage receiving port 321 is tilted downward, when the user places the cleaning device 90 on the tray 2, it is convenient for the user to adjust the sewage outlet 93 of the cleaning device 90 to be located obliquely above the sewage outlet 321, so as to reduce interference and obstruction during docking, and facilitate the docking of the sewage outlet 93 of the cleaning device 90 with the sewage receiving port 321, so that the dirt discharged by the cleaning device 90 can pass through the sewage receiving port 321 and flow into the sewage receiving portion 32.

[0072] In another embodiment of the present disclosure, the end face of the sewage receiving port 321 is constructed to extend in the horizontal plane from the position connected to the sewage receiving portion 31, so that the end face of the sewage receiving port 321 is constructed to be flush with the position where the sewage receiving port 321 is connected to the sewage receiving portion 31 in the height direction. In this way, when the sewage receiving port 321 extends in the horizontal direction, after the user places the cleaning device 90 on the tray 2, the sewage receiving portion 32 can effectively hold up the cleaning device 90 of the present disclosure, and can effectively prevent the cleaning device 90 from sliding off from above the sewage receiving portion 32, ensuring that the sewage discharge port 93 of the cleaning device 90 is always docked with the sewage receiving port 321 during the process of the cleaning device 90 discharging dirt, thereby preventing the dirt discharged by the cleaning device 90 from flowing outside the cleaning base station 10 and causing pollution.

[0073] Further, such as Figure 10 As shown, in one embodiment of the present disclosure, the plane where the sewage receiving port 321 is located is denoted as surface S, and the area of ​​the sewage receiving portion 31 on surface S is constructed to be smaller than the area of ​​the sewage receiving port 321 on surface S. Since the area of ​​the sewage receiving portion 31 on surface S is smaller than the area of ​​the sewage receiving port 321 on surface S, it can be ensured that the area of ​​the sewage receiving port 321 can meet the demand, thereby expanding the area of ​​the sewage outlet 93 of the cleaning device 90 as much as possible, thereby improving the sewage discharge speed of the cleaning device 90; it can also reduce the area of ​​the sewage receiving portion 31 on surface S, thereby reducing the overall area of ​​the sewage trough 3, thereby saving the space occupied by the sewage trough 3 and greatly reducing the overall volume of the base 1.

[0074] Further, such as Figure 10 As shown, in one embodiment of the present disclosure, the dirt receiving portion 32 is constructed as a tapered structure with a decreasing cross-sectional area from top to bottom. Since the dirt receiving portion 32 is primarily used to receive dirt discharged by the cleaning device 90, a tapered structure with a decreasing cross-sectional area from top to bottom facilitates the dirt receiving portion 32 to direct the dirt discharged from the cleaning device 90 into the dirt receiving portion 31 after receiving the dirt, effectively saving the space occupied by the dirt receiving portion 32.

[0075] 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 consistency of waste discharge, facilitating gravity-driven waste discharge. Furthermore, the dirt receiving portion 32 is primarily located outside the inner cavity of the base 1, connecting to the drain port of the cleaning device 90. The dirt receiving portion 32 substantially does not occupy the inner cavity 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.

[0076] 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.

[0077] Of course, it is understandable that when the first side wall 323 and the second side wall 324 are configured so that their bottoms are inclined toward each other, and the enclosing wall 322, the first side wall 323, and the second side wall 324 are in the shape of a square funnel as a whole, the first side wall 323 and the second side wall 324 can also receive dirt from the cleaning device 90 and guide the dirt discharged by the cleaning device 90 along the first side wall 323 and the second side wall 324 to flow to the dirt receiving portion 31. The enclosing wall 322, the first side wall 323, and the second side wall 324 can be integrally formed, or can be formed as separate parts and then fixedly connected together, and the specific processing technology is not limited here.

[0078] like Figure 5 As shown, in one embodiment of the present disclosure, the side of the dirt-receiving portion 32 opposite to the enclosing wall 322 is open and used to communicate with the inner cavity of the dirt-receiving portion 31, and the projection of the dirt-receiving portion 32 toward the dirt-receiving portion 31 does not exceed the maximum diameter of the dirt-receiving portion 31. Since the side of the dirt-receiving portion 32 opposite to the enclosing wall 322 is open and used to communicate with the inner cavity of the dirt-receiving portion 31, it is convenient for dirt to flow from the dirt-receiving portion 32 into the dirt-receiving portion 31, and since the projection of the dirt-receiving portion 32 toward the dirt-receiving portion 31 does not exceed the maximum diameter of the dirt-receiving portion 31, the overall projection of the dirt-receiving portion 32 can fall between the areas of the dirt-receiving portion 31, and there will be no left-right relative misalignment between the dirt-receiving portion 32 and the dirt-receiving portion 31, which is conducive to reducing the size of the base 1 in the axial direction of the roller brush groove 21.

[0079] As mentioned above, the sewage trough 3 includes a sewage receiving portion 31 located in the base 1 and a sewage receiving portion 32 communicating with the inner cavity of the sewage receiving portion 31 ; the sewage receiving portion 32 is constructed to have a sewage receiving port 321 for receiving the sewage outlet 93 of the cleaning device 90 .

[0080] like Figures 7 to 10 As shown, in one embodiment of the present disclosure, the sewage receiving portion 32 has a sewage discharge surface 325, and at least part of the dirt flowing in from the sewage receiving port 321 is constructed to be guided from the sewage discharge surface 325 to the inner cavity of the sewage receiving portion 31; 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.

[0081] During 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 portion 32, and the dirt discharged by the cleaning device 90 can be discharged into the sewage trough 3. Among them, the sewage surface 325 of the sewage receiving portion 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 sewage receiving portion 31, that is, at least part of the dirt flowing out of the sewage outlet 93 can flow from the sewage surface 325 to the inner cavity of the sewage receiving portion 31; the sewage receiving portion 31 is arranged in the base 1, mainly for temporarily storing dirt, and guiding the dirt discharged by the cleaning device 90 into the sewage pipe 6, so that the dirt is discharged to the outside.

[0082] Specifically, since the area on the sewage discharge surface 325 corresponding to the sewage outlet 93 is constructed as a flat surface or a continuous smooth curved surface, the dirt will flow downward smoothly when it falls from the sewage outlet 321 to the sewage discharge surface 325, ensuring that the dirt continues to flow to the sewage pipe 6 with greater kinetic energy. It can also prevent the dirt from splashing out of the sewage outlet 321 when it falls on the sewage discharge surface 325 and falling onto the base 1 or tray 2 of the cleaning base station 10. There is no need for the user to perform secondary cleaning of the cleaning base station 10, which effectively reduces the user's usage burden and improves the user's usage experience.

[0083] like Figure 9 and Figure 10 As shown, in one embodiment of the present disclosure, the dirt-receiving portion 32 is configured to be located in front of the dirt-receiving portion 31, and the top of the dirt-receiving portion 32 is configured to extend from the dirt-receiving portion 31 toward the location of the tray 2 to form a dirt-receiving opening 321. Since the dirt-receiving portion 32 is located in front of the dirt-receiving portion 31 and the top of the dirt-receiving portion 32 extends from the dirt-receiving portion 31 toward the location of the tray 2 to form the dirt-receiving opening 321, it is convenient for the sewage outlet 93 of the cleaning device 90 to be located above the sewage-receiving portion 32 and docked with the sewage outlet 321; dirt discharged by the cleaning device 90 can flow through the sewage outlet 321 into the dirt-receiving portion 32, and then into the sewage-receiving portion 31. Since the sewage receiving portion 32 is located on the front side of the sewage containing portion 31 and is connected to the side wall of the sewage containing portion 31, it protrudes from the base 1 toward the front side, so that the sewage receiving portion 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, and does not occupy the cavity volume of the base 1.

[0084] like Figure 4 As shown, in one embodiment of the present disclosure, in the front-to-back direction of the base 1, the end of the sewage discharge surface 325 adjacent to the tray 2 is recorded as end A, and the end away from the tray 2 is recorded as end B; the line connecting end A and end B is constructed so that the angle between them and the central axis of the sewage outlet 93 is less than or equal to 40°. Since the angle between the line connecting the end A of the sewage discharge surface 325 adjacent to the tray 2 and the end B away from the tray 2 and the central axis of the sewage outlet 93 is less than or equal to 40°, it can be further ensured that when the dirt falls from the sewage outlet 93 of the cleaning equipment 90 to the sewage discharge surface 325, it will not have a large impact on the sewage discharge surface 325, thus preventing the dirt from splashing out of the sewage receiving port 321 when it falls on the sewage discharge surface 325 and falling onto the base 1 or tray 2 of the cleaning base station 10, and it can flow smoothly downward under the action of gravity, ensuring that the dirt continues to flow to 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 shown Figure 4As shown, more precisely, since the drainage surface 325 is used to receive the dirt falling from the drainage outlet 90 of the cleaning equipment 90, the area projected on the drainage surface 325 along the extension direction of the body of the cleaning equipment 90 with the drainage outlet 90 is recorded as W. Since the drainage surface 325 may be slightly curved, the tangent direction of the center point of W is used as a reference, and the angle between the tangent direction of the center point of W and the vertical direction does not exceed 40°.

[0085] Further, such as Figure 4 As shown, in one embodiment of the present disclosure, in the front-to-back direction of the base 1, the end of the sewage outlet 93 away from the base 1 is denoted as end C, and the end adjacent to the base 1 is denoted as end D; wherein the portion between ends C and D is configured to be located between ends A and B along the orthographic projection of the central axis of the sewage outlet 93. Since the orthographic projection of the portion of the sewage outlet 93 between the front end C away from the base 1 and the rear end D adjacent to the base 1 on the central axis of the sewage outlet 93 is located between the aforementioned ends A and B, it is ensured that after falling from the sewage outlet 93 of the cleaning device 90, the dirt can fall into the area where the sewage discharge surface 325 is located, and will not fall directly into other locations such as the inner cavity of the sewage receiving portion 31, thereby preventing the dirt from falling directly into the inner cavity of the sewage receiving portion 31 and splashing, and effectively exerting the diversion function of the sewage discharge surface 325.

[0086] Furthermore, in one embodiment of the present disclosure, the orthographic projection of the sewage outlet 93 on its central axis is located within the orthographic projection range of the sewage surface 325 on the central axis of the sewage outlet 93. In this way, it can further ensure that after the dirt falls from the sewage outlet 93 of the cleaning equipment 90, it can fall on the sewage surface 325 and flow obliquely downward along the sewage surface 325, instead of falling directly into other positions such as the inner cavity of the sewage receiving part 31 and being unable to use kinetic energy to continue to flow to the sewage pipe 6.

[0087] like Figure 4 As shown, in one embodiment of the present disclosure, the end D of the sewage outlet 93 is projected along the central axis of the sewage outlet 93 and coincides with the bottom end of the sewage receiving part 32. In this way, it can ensure that the sewage outlet 03 can be projected on the sewage surface 325, effectively utilizing the sewage surface 325 to guide the flow of dirt, and there is no need to set an excessively long sewage surface 325, thereby effectively ensuring the miniaturization of the cleaning base station 10 disclosed in the present disclosure.

[0088] like Figure 7As shown, in one embodiment of the present disclosure, the pollution-receiving portion 32 includes an enclosing wall 322 on a side away from the pollution-containing portion 31, and the inner wall of the enclosing wall 322 is configured as a pollution discharge surface 325; the enclosing wall 322 is configured to extend obliquely downward from the top of the pollution-receiving portion 32 to dock with the corresponding position of the pollution-containing portion 31; the pollution-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, and the first side wall 323, the second side wall 324, and the enclosing wall 322 are configured to enclose the pollution-receiving portion 32 on the pollution-containing portion 31. Since the inner wall of the enclosing wall 322 can serve as the pollution discharge surface 325, there is no need to separately set up the pollution discharge surface 325 in the pollution-receiving portion 32, thereby effectively saving the materials required for the processing of the pollution-receiving portion 32.

[0089] Furthermore, in one 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. This further ensures that after dirt falls from the sewage outlet 93 of the cleaning device 90, it can all fall onto the enclosing wall 322 and flow obliquely downward along the enclosing wall 322, rather than directly falling into other locations such as the inner cavity of the sewage receiving portion 31. This prevents the dirt from directly falling into the inner cavity of the sewage receiving portion 31 and being splashed, and from being unable to utilize kinetic energy to continue flowing toward the sewage pipe 6.

[0090] like Figure 10 As shown, in one embodiment of the present disclosure, the outlet of the drain chute 3 is provided with an end E located at the front side and an end F located at the rear side, and the extension line of point AB is located between ends E and F of the drain chute 3. In this way, the dirt discharged from the drain outlet 93 can directly fall onto the outlet of the drain chute 3 after passing through the drain surface 325 of the dirt receiving portion 32, thereby minimizing obstruction on the drainage path. In addition, the dirt discharged later can also have a gravity impact on the dirt discharged earlier, which is more conducive to the discharge of dirt.

[0091] Further, such as Figure 10 As shown, in one embodiment of the present disclosure, the outlet center point G of the drain chute 3 is positioned such that the extension line of points AB lies between end E and center G, meaning that end B is located above the line connecting AE. This allows waste discharged from the drain outlet 93 to pass through the drainage surface 325 of the waste receiving portion 32 and then directly fall onto the outlet of the drain chute 3, minimizing obstruction in the drainage path. It should be understood that the extension line of points AB lying between end E and center G includes the case where it passes through either end E or center G.

[0092] Similar, such as Figure 10As shown, in one embodiment of the present disclosure, the intersection H of lines DF and the dirt-receiving portion 32 or the dirt-receiving portion 31 is located below point I, that is, there is no obstruction on the DF connecting line. This further ensures that the dirt discharged from the drain outlet 93 can directly fall into the drain chute outlet after passing through the drain surface 325 of the dirt-receiving portion 32, minimizing obstruction in the drain path.

[0093] like Figure 4 As shown, in one embodiment of the present disclosure, the inclination angle of the drainage surface 325 relative to the horizontal plane is configured to decrease continuously from top to bottom. It can be understood that the inclination angle of any point of the drainage surface 325 relative to the horizontal plane is the angle formed by the tangent line passing through the point and the horizontal plane, and the maximum angle is a right angle. Figure 4 The inclination angle of the drainage surface 325 relative to the horizontal plane is always acute. In this way, when the dirt discharged by the cleaning device 90 falls on the drainage surface 325 and flows along the drainage surface 325, it can be guided toward the bottom of the drainage trough 3 under the action of the drainage surface 325. As a result, when the dirt flows from the drainage surface 325 to the inner cavity of the dirt receiving portion 31, it can flow to the bottom of the drainage trough 3 as quickly as possible without impacting other locations in the inner cavity of the dirt receiving portion 31. This effectively utilizes the dirt's own kinetic energy and promotes the quickest possible removal of the dirt.

[0094] Specifically, such as Figure 4 As shown, in one embodiment of the present disclosure, the area of ​​the sewage outlet 93 is constructed to be smaller than the area of ​​the sewage receiving port 321; when the cleaning device 90 is placed on the cleaning base station 10, the orthographic projection of the sewage outlet 93 on its central axis is located within the sewage receiving port 321. In this way, it can be ensured that when the cleaning device 90 is placed on the cleaning base station 10, the dirt discharged from the sewage outlet 93 of the cleaning device 90 can all fall into the sewage receiving port 321 and will not flow outside the sewage receiving port 321 and cause pollution to the cleaning base station 10. Moreover, after the dirt falls into the sewage receiving portion 32, even if splashing occurs, it is unlikely to splash outside the sewage receiving port 321, thereby preventing the dirt from splashing out of the sewage receiving port 321.

[0095] like Figure 18 As shown, in one embodiment of the present disclosure, a filter assembly 326 is provided in the inner cavity of the sewage receiving portion 32, the filter assembly 326 is provided in the sewage receiving port 321, and is constructed to be removable from the sewage receiving port 321, and the filter assembly 326 is constructed to extend downward to form a filter cavity; when the cleaning equipment 90 is placed on the cleaning base station 10, the sewage outlet 93 has its positive projection on its central axis located in the filter cavity.

[0096] By disposing a filter assembly 326 within the inner cavity of the dirt-receiving portion 32, during operation of the cleaning base station 10 of the present disclosure, all dirt discharged by the cleaning device 90 will pass through the filter assembly 326. Larger solid dirt will be filtered within the filter cavity, while the remaining dirt will fall onto the discharge surface 325 and be discharged into the drain trough 3. Since the orthographic projection of the drain outlet 93 on its central axis is located within the filter cavity when the cleaning device 90 is placed within the cleaning base station 10, it is ensured that all dirt discharged by the cleaning device 90 is filtered by the filter assembly 326, and there will be no situation where some dirt is not filtered by the filter assembly 326 and directly flows into the drain trough 3.

[0097] like Figure 10 As shown, in one embodiment of the present disclosure, the inclination angle of the drainage surface 325 relative to the horizontal plane is configured to be smaller than the inclination angle of the side wall of the sewage receiving portion 31 located below the enclosing wall 322. Since the inclination angle of the drainage surface 325 relative to the horizontal plane is smaller than the inclination angle of the side wall of the sewage receiving portion 31 located below the enclosing wall 322, the side wall of the sewage receiving portion 31 located below the enclosing wall 322 will deviate downward from the downward extension path of the drainage surface 325. When the sewage discharged by the cleaning equipment 90 flows downward along the drainage surface 325 to the sewage receiving portion 31, most of it will no longer continue to flow downward along the side wall of the sewage receiving portion 31, but will rush into the middle of the inner cavity of the sewage receiving portion 31, thereby minimizing the generation of vortexes or splashing when the sewage flows into the sewage receiving portion 31, reducing the impact between the sewage, ensuring the smooth flow of the sewage flow, and effectively increasing the discharge speed of the sewage from the bottom of the sewage receiving portion 31.

[0098] like Figure 17 As shown, in one embodiment of the present disclosure, at least one guide rib 327 is provided on the drainage surface 325. The guide rib 327 is configured to extend along the direction of dirt flow on the drainage surface 325. The extension direction of the guide rib 327 can be parallel to the dirt flow direction, or can be arranged at an angle to the dirt flow direction. In this way, after the dirt discharged by the cleaning device 90 falls on the drainage surface 325, it can flow along the extension direction of the guide rib 327, reducing the splashing of dirt on the drainage surface 325 and preventing the dirt from impacting the first side wall 323 and the second side wall 324. This can effectively reduce the kinetic energy loss of the dirt and ensure that the dirt flows diagonally downward along the drainage surface 325 as quickly as possible.

[0099] like Figure 3 and Figure 4As shown, in one embodiment of the present disclosure, in the cleaning system of the present disclosure, the cleaning equipment 90 is provided with a sewage outlet 93, and a lower cover 95 is provided at the sewage outlet 93, and the lower cover 95 has a first position of closing the sewage outlet 93 and a second position of opening the sewage outlet 93; the cleaning equipment 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 outlet 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 the side of the sewage discharge surface 325, and the opening angle range of the lower cover 95 is 90°-100°.

[0100] In this way, during the operation of the cleaning device 90 disclosed herein, the lower cover 95 can be rotated from the first position to the second position to open the sewage outlet 93; because 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 the side of the sewage discharge surface 325, the opening angle range of the lower cover 95 is 90°-100°, and the dirt in the cleaning device 90 can flow along the lower cover 95, and the lower cover 95 will not hinder the flow of dirt, thereby ensuring the normal flow of dirt in the sewage bucket 92.

[0101] like Figure 18 As shown, in one embodiment of the present disclosure, the dirt-receiving portion 32 is located on the base 1. The base 1 is provided with a mounting opening 4 on one side of the tray 2 for adapting to the dirt-receiving opening 321. The end surfaces on both sides of the mounting opening 4 are constructed to be higher than the end surfaces of the dirt-receiving opening 321. When the user places the cleaning device 90 on the tray 2, the cleaning device 90 partially enters the mounting opening 4, and the sewage outlet 93 is located above the sewage outlet 321. Since the end surfaces on both sides of the mounting opening 4 are higher than the end surfaces of the sewage outlet 321, it can effectively prevent dirt from splashing out from the two sides of the mounting opening 4 when the cleaning device 90 is discharging dirt, thereby preventing the dirt from contaminating the outside world and improving the user experience.

[0102] Specifically, such as Figure 4As shown, the lower cover 95 of the cleaning device 90, which blocks the sewage outlet 93, is rotatably connected to the sewage bucket 92 at the C end via a rotating shaft. When the cleaning device 90 needs to discharge sewage, the lower cover 95 is unlocked from the sewage bucket 92 at the D end and then rotated open about the rotating shaft at the C end 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 outlet 321 away from the base 1. Moreover, the angle of rotation of the lower cover 95 of the sewage bucket 92 is greater than or equal to 90 degrees, so that when the dirt is discharged from the sewage outlet 93, the lower cover 95 will not block the sewage in 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 being rotated and opened, if the rotation opening angle of the lower cover 95 is too large, the space required at the sewage discharge surface 325 will also be correspondingly larger, and the overall size of the sewage receiving portion 32 that protrudes beyond the outside of the base 1 will have to be larger, and the cleaning equipment 90 needs to be taken and placed on the cleaning base station 10. The size of the sewage receiving portion 32 protruding from the outside of the base 1 is too large, and when the cleaning equipment 90 is taken and placed, its floor brush assembly or the rear side of the body will interfere with the sewage receiving portion 32, resulting in the need to redesign the cleaning base station 10. Therefore, considering the sewage discharge and the placement of the cleaning equipment 90, the rotation opening angle of the lower cover 95 of the sewage tank 92 is not greater than 100°, and in the open state, it abuts against the sewage discharge surface 325, so as to ensure that the cleaning equipment can be docked and taken conveniently without affecting the sewage discharge.

[0103] Furthermore, when the cleaning device 90 is in an upright state, its upright body generally forms an acute angle with the floor brush assembly, and the upright body is tilted forward. In addition, the upright body generally carries heavy components such as a fan unit and a battery. In order to carry the cleaning device 90 and prevent the cleaning device 90 from tipping forward on the base station, Figure 18 As shown, in one embodiment of the present disclosure, the end faces on both sides of the mounting port 4 are constructed to extend toward the front thereof to form ribs 41, and the ribs 41 are constructed to engage with the bottom of the cleaning device 90 body 91 or the sewage bucket 92. That is, a groove can be provided at the bottom of the body 91 or the bottom of the sewage bucket 92. Specifically, at least two symmetrical grooves are provided at the bottom of the body 91 or the bottom of 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 ribs 41 on the front side of the mounting port 4 can be engaged with the grooves at the bottom of the cleaning device 90 body 91 or the grooves at the bottom of the sewage bucket 92, thereby effectively preventing the cleaning device 90 from sliding off the mounting port 4 or relatively deflecting, thereby ensuring the normal progress of the sewage discharge process. As shown Figure 18 As shown, the ribs 41 on both sides of the mounting port 4 are not connected together, but a gap is formed in the middle area, which can be used to avoid the sewage outlet 93 of the fuselage 91 or the sewage bucket 92, making it convenient for the user to place the cleaning equipment 90 in the mounting port 4.

[0104] like Figure 9 As shown, in one embodiment of the present disclosure, the dirt receiving portion 31 is constructed to have at least a variable diameter portion whose size increases from top to bottom, and the dirt receiving portion 32 is constructed to be at least connected to the variable diameter portion and is constructed to be transitionally connected to the side wall of the variable diameter portion. The dirt discharged from the sewage receiving portion 32 mainly flows to the middle and lower part of the sewage receiving portion 31 and is then discharged through the sewage discharge pipe 6. The middle and lower part of the sewage receiving portion 31 is an effective part for temporarily storing dirt. The sewage receiving portion 31 is designed to have at least a variable diameter portion that increases in size from top to bottom, which can effectively expand the volume of the inner cavity in the sewage receiving portion 31 that plays the main role of temporarily storing dirt, thereby temporarily storing dirt discharged by the cleaning equipment 90. Even if blockage occurs, the dirt is mainly accumulated in the middle and lower part of the sewage receiving portion 31, avoiding the distance between the dirty water surface and the sewage receiving port 321 being too close; at the same time, it can also effectively reduce the volume of the upper part of the sewage receiving portion 31 that has a smaller role in storing dirt. In this way, the structure of the sewage receiving portion 31 is reasonably designed, so that the sewage receiving portion 31 can maximize the reduction of the space occupied by the sewage receiving portion 31 while ensuring sufficient capacity; and as mentioned above, the sewage receiving portion 32 is a tapered structure with a smaller volume from top to bottom, which can ensure that the overall width of the sewage trough 3 disclosed in the present invention will not be significantly increased. Moreover, since the sewage receiving part 32 is at least connected to the variable diameter part and is transitionally connected to the side wall of the variable diameter part, that is, the connection position of the sewage receiving part 32 and the variable diameter part is located on the extension path of the variable diameter part itself, the sewage receiving part 32 does not extend into the inner cavity of the sewage containing part 31, and the sewage receiving part 32 will not form an obstruction in the inner cavity of the sewage containing part 31, and will not hinder the falling of sewage; moreover, there will be no cleaning dead corners at the connection position of the sewage receiving part 32 and the sewage containing part 31, thereby facilitating the cleaning of the sewage trough 3 and ensuring that the sewage trough 3 can be cleaned.

[0105] Specifically, such as Figure 9As shown, in one embodiment of the present disclosure, the dirt holding portion 31 includes a first portion 311 located at the top and a second portion 312 located at the bottom, and the first portion 311 is constructed to dock with the second portion 312; the size of the first portion 311 is constructed to have a gradually expanding structure with the cross-sectional area increasing from top to bottom; the dirt holding portion 32 is constructed to be transitionally connected to the first portion 311, and the size of the second portion 312 is constructed to have a gradually shrinking structure with the cross-sectional area decreasing from top to bottom. The first portion 311 of the dirt holding portion 31 has a gradually expanding structure with a larger cross-sectional area from top to bottom, which can facilitate the formation of a variable diameter portion that increases in size from top to bottom, thereby temporarily storing dirt during the process of the cleaning device 90 discharging dirt. The cross-sectional area of ​​the dirt holding portion 31 gradually increases from top to bottom, and the dirt holding portion 32 docks on both sides of the first portion 311, thereby further expanding the storage area below, which is conducive to expanding the blockage capacity; while the cross-sectional area of ​​the second portion 312 gradually decreases from top to bottom until it docks with the sewage pipe 6, thereby facilitating the dirt holding portion 31 to guide the dirt discharged by the cleaning device 90 into the sewage pipe 6. After the cleaning device 90 completes the sewage discharge, it is ensured that all dirt can be discharged into the sewage pipe 6, avoiding the residue in the dirt holding portion 31. In addition, the cross-sectional area of ​​the first portion 311 gradually increases from top to bottom, while the cross-sectional area of ​​the second portion 312 gradually decreases from top to bottom, which is conducive to the flushing water flowing out of the top of the sewage trough flowing down along the inner wall of the sewage trough to flush the sewage trough. Furthermore, the first part 311 is a continuously smooth and gradually expanding structure with a cross-sectional area gradually increasing from top to bottom, and the second part 312 is a continuously smooth and gradually contracting structure with a cross-sectional area gradually decreasing from top to bottom. First, the continuous and smooth structure is conducive to the flow of flushing water. Secondly, under the condition of being conducive 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 sewage receiving part 32 docked with both sides of the first part 311 is maximized, that is, the area enclosed by the sewage receiving part 32 is maximized, and the volume enclosed by the sewage receiving part 32 and the sewage receiving part 31 is maximized, thereby increasing the blockage capacity and helping to reduce the occupied volume of the sewage trough. Specifically, as Figure 9 As shown, in one embodiment of the present disclosure, the sewage receiving portion 32 is formed on the first portion 311 of the sewage receiving portion 31 and includes an enclosure wall 322 on one side away from the sewage receiving portion 31. The enclosure wall 322 is constructed to extend obliquely downward from the top of the sewage receiving portion 32 to transitionally connect with the bottom of the first portion 311. In this way, the sewage discharged by the cleaning equipment 90 can flow directly to the bottom of the first portion 311, that is, the position where the first portion 311 and the second portion 312 are connected, which is the part with the largest inner diameter of the sewage receiving portion 31. This can effectively reduce the impact and splashing of dirt on the inner wall of the sewage receiving portion 31, avoid the formation of vortexes in the sewage receiving portion 31, reduce the residence time of dirt in the sewage receiving portion 31, and improve the sewage discharge efficiency of the sewage trough 3 of the present disclosure.

[0106] Furthermore, in one embodiment of the present disclosure, the inclination angle of the enclosing wall 322 relative to the horizontal plane is configured to be smaller than the inclination angle of the portion of the second portion 312 located below the enclosing wall 322. Figure 10 As shown, the side walls 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 equipment 90 flows downward along the enclosing wall 322 to the second part 312, most of it will no longer continue to flow downward along the side walls of the second part 312, but will rush into the middle of the inner cavity of the sewage holding portion 31, thereby avoiding as much as possible the generation of vortexes or splashing when the sewage flows to the second part 312, reducing the impact between the sewage, ensuring the smooth flow of the sewage flow, and effectively improving the discharge speed of the sewage from the bottom of the sewage holding portion 31.

[0107] It can be understood that the inclination angle of the enclosing wall 322 relative to the horizontal plane is smaller than the inclination angle of the part of the second part 312 located below the enclosing wall 322, which means that the inclination angle of any point of the enclosing wall 322 relative to the horizontal plane is smaller than the inclination angle of any point of the part of the second part 312 located below the enclosing wall 322.

[0108] like Figure 9 As shown, in one embodiment of the present disclosure, the sewage receiving port 321 is configured to extend from the position connected to the first portion 311 toward the tray 2 to extend beyond the second portion 312. Since the sewage receiving port 321 extends from the position connected to the first portion 311 toward the tray 2 to extend beyond the second portion 312, it is possible to facilitate docking of the sewage receiving port 321 with the cleaning device 90, thereby increasing the area of ​​the sewage receiving port 321 within a limited space, and facilitating docking of the sewage outlet 93 of the cleaning device 90 with the sewage receiving port 321.

[0109] like Figure 9 As shown, in one embodiment of the present disclosure, the dimension of the first portion 311 in the height direction is greater than the dimension of the second portion 312 in the height direction.

[0110] It can be understood that since the first part 311 of the dirt holding part 31 is formed with the dirt holding part 32, the dirt holding part 32 is used to guide the sewage in the sewage bucket of the cleaning equipment to the sewage outlet, and the first part 311 temporarily stores the dirt in the process of the cleaning equipment 90 discharging the dirt, and the second part 312 mainly functions to guide the dirt discharged by the cleaning equipment 90 into the sewage pipe 6 and temporarily store the dirt together with the dirt holding part 32 when the sewage trough is blocked; when the height of the first part 311 is greater than the height of the second part 312, it is beneficial for the dirt holding part 32 to guide the dirt 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, prevent the dirt from overflowing from the sewage trough 3 when the cleaning equipment 90 discharges the sewage too quickly or the sewage pipe 6 is blocked, and can form an overall shorter and fatter area in the second part 312, which is convenient for guiding the dirt to be quickly discharged from the sewage receiving part 31 and reducing the overall height of the sewage receiving part 31. At the same time, when flushing the sewage trough, the height of the first part 311 is greater, and the slope of the arc surface of the first part 311 is greater, which is conducive to 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 the base station is provided with a partial horizontal sewage pipe in addition to the sewage trough, the sewage pipe has a capacity. Therefore, the height of the second part can be appropriately reduced to reduce the overall height without affecting the capacity below the detection position 81 recorded below.

[0111] As attached Figure 10 As shown, OJ is a vertical line passing through point B, OEF is a horizontal line passing through points E and F on the upper surface of the bottom outlet of the sewage trough 3, AJ is a horizontal line passing through point A, ABK is a straight line passing through points AB, point K is the intersection of the AB extension line and the OEF line, 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.

[0112] When designing the sewage trough, since the sewage receiving port of the sewage receiving part needs to be docked with the body of the cleaning equipment, point A is the point on the sewage receiving port 321 that is farthest from the front wall 11 of the base 1, and is determined. The plane where the bottom outlet of the sewage trough 3 is located is also basically determined, which is similar to 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 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 trough 3, recorded as S2, and h1+h2=|OJ|=S2. Point B is the intersection of the sewage receiving part extending out of the base at point A at a certain angle (i.e., the acute angle formed by line AB and the vertical line OJ. For the convenience of calculation and explanation, this angle is approximated as the sewage discharge angle θ) to the base and intersects with the vertical outer surface of the base. That is, the vertical line OJ is fixed, which is basically the vertical surface of the front side of the base. Point B is basically a point on or near the vertical surface of the front side of the base. According to the different sewage discharge angles, point B can move up and down in the direction of the vertical line OJ. Therefore, the length of AJ |AJ| is also basically fixed, 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, which 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 EF. 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, the requirement that the sewage discharge angle is within 40° is not met. Therefore, the minimum value of h1 is based on the requirement to meet the sewage discharge angle. That is, (|AJ| / tanθ) / (|OJ|-|AJ| / tanθ) ≤ h1 / h2 ≤ |AJ| / |OE|, where |OE| is the horizontal distance from point (O) where the outlet of the drain chute 3 is close to the front wall 11 of the base 1 to the front wall 11 of the base 1 or its vicinity, denoted as S3. That is, (S1 / tanθ) / (S2-S1 / tanθ) ≤ h1 / h2 ≤ S1 / S3.

[0113] In addition, in order to prevent the dirt from accumulating in the sewage trough 3 when the cleaning equipment 90 is discharging sewage and cannot be discharged in time, the length of the outlet |EF| of the sewage trough 3 is set to be no less than the length |AJ|. At the same time, in order to miniaturize the base station, the length of the outlet |EF| of the sewage trough 3 does not need to be too large. Optimally, |EF|≈|AJ|.

[0114] In this example, according to the general size of the cleaning device 90 in the art, |OJ|≈2.3|AJ|.

[0115] In this example, since the sewage discharge angle needs to be guaranteed to be within 40° to prevent dirt from splashing out when it falls, when the sewage discharge angle is exactly equal to 40°, point B is at the highest allowable position. At this time, h1 meets the first condition: |AJ| / h1min=tan40°, h1min=1.2|AJ|, then h2max=1.1|AJ|, that is, h1 / h2≥1.1.

[0116] As mentioned above, the extension line of AB optimally falls between the two points EF, so that the dirt, after being guided by the AB section, falls directly into the range of the bottom outlet EF of the drain trough 3. 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. In theory, the outlet point E of the drain trough 3 can be infinitely close to the front surface of the base, but |EF| is determined. The outlet of the drain trough 3 needs to be connected to the pipe opening of the sewage pipe 6. The outlet of the drain trough 3 is generally located in the center of the base, and various other components need to be accommodated in the base station. In this embodiment, the distance between point E and the vertical line OJ (front surface of the base) is |OE|≈0.5|AJ|. When the extension line of AB passes through point E, h1 / h2=2, and the drainage angle is 33°; when the extension line of AB passes through point F, h1 / h2=0.7, and the drainage angle is 42°, which does not meet the requirement that the drainage angle is less than 40°. Therefore, taking all factors into consideration, the optimal range of h1 / h2 is 1.1-2.

[0117] In addition, taking into account the smoothness of sewage discharge, the flushing of the sewage trough, and the maximization of the volume of the sewage trough, point B is set as the maximum transverse diameter of the sewage holding part, that is, as the boundary between the first part 311 and the second part 312. The maximum transverse diameter of the sewage holding part is directly related to the thickness of the base station. The thicker the base station, the larger the maximum transverse diameter of the sewage holding part can be. It can be imagined that in order to ensure the smoothness of sewage discharge and the flushing of the sewage trough, there should be only one smooth arc surface from point B to the outlet point E of the sewage trough. On this basis, if the maximum transverse diameter of the sewage holding part is above point B, imagine that Figure 10If the dirt receiving portion in the structure moves upward as a whole, the dirt guided by the AB section will most likely fall into the BE section and then be discharged, rather than falling directly between the outlets EF. If the maximum transverse diameter of the dirt receiving portion is below point B, the cross-sectional area of ​​the cavity surrounded by the dirt receiving portion and the first part 311 above point B will become smaller, resulting in a reduction in the volume of the cavity. In order to ensure that the BE section has only one smooth arc surface, the arc surface of the original dirt receiving portion needs to be retracted to the BE arc surface, and the overall volume will also be reduced. Therefore, in general, taking point B as the point with the maximum transverse diameter of the dirt receiving portion is the optimal embodiment. That is, the intersection of the dirt receiving portion and the dirt receiving portion is the point with the maximum transverse diameter of the dirt receiving portion, which is the dividing point between the first part 311 and the second part 312. In the above analysis, in order to prevent dirt from splashing back when it falls on the discharge surface, the 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 vertical dimension of the first part 311 is greater than h1. Therefore, in order to prevent dirt from splashing back, the vertical dimension of the first portion 311 is larger than the vertical dimension of the second portion 312 .

[0118] like Figures 6 to 10 As shown, in one embodiment of the present disclosure, the size of the second portion 312 in the first direction is greater than its size in the second direction. That is, the thickness of the dirt holding portion 31 in the front-to-back direction is less than the width in the left-to-right direction. Since the tray of the base station needs to accommodate the floor brush of the cleaning equipment, that is, the base station has a size 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 portion 31 can fully utilize the space of the base station in the axial direction of the roller brush groove 21. Under the premise of ensuring the volume of the dirt holding portion 31 of the present disclosure, the thickness of the dirt holding portion 31 and the base 1 on which it is located is effectively reduced, which is conducive to the miniaturization of the base station, increases user acceptance and favorability, and thus facilitates the layout of the cleaning base station 10 of the present disclosure.

[0119] The sewage outlet of existing cleaning base stations is mostly set at the back of the base station, and the sewage outlet is then connected to a horizontal extension pipe to the sewer outlet. In this way, the dirt discharged from the sewage trough flows through a turn to the sewage outlet of the base station, and then passes through another turn at the sewage outlet of the base station to enter the external extension pipe and flow away. The dirt has made two 90-degree turns, which greatly consumes the kinetic energy of the dirt and makes the sewage discharge not smooth enough.

[0120] like Figure 5 As shown, in one embodiment of the present disclosure, the sewage pipe 6 is constructed to be connected to the bottom of the sewage trough 3; the sewage pipe 6 has at least a sewage section 62 extending in the transverse direction, and a connecting section 61 connecting the sewage section 62 with the bottom of the sewage trough 3, one end of the connecting section 61 is constructed to extend toward the bottom of the sewage trough 3 until it is connected to the bottom of the sewage trough 3, and the other end is constructed to extend toward the direction of the sewage section 62 until it is connected to the sewage section 62, and the sewage section 62 extends along the first direction.

[0121] 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 trough 3 in the base 1. The dirt will flow from the bottom of the sewage trough 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 along the first direction, the sewage section 62 can be effectively arranged using the overall width of the cleaning base station 10, thereby reducing the overall length of the cleaning base station of the present disclosure in the second direction.

[0122] Moreover, since the sewage discharge section 62 extends along the first direction, the dirt only needs to go through one turn in the connecting section 61 when flowing to the sewage discharge section 62. The sewage discharge section 62 is consistent with the extension direction of the external extension pipe connected to the sewage outlet of the base station, thereby effectively reducing the kinetic energy loss of the dirt during the sewage discharge process and making the sewage discharge smoother.

[0123] It can be understood that the laterally extending sewage discharge section 62 may extend in the horizontal direction, may not be completely parallel to the horizontal plane, or may extend gradually downward, that is, both the downward extension and the horizontal extension may be laterally extended.

[0124] like Figure 1 、 Figure 5 、 Figure 6 As shown, in one embodiment of the present disclosure, the sewage discharge section 62 has a sewage discharge outlet 620, and the sewage discharge outlet 620 is located on the side of the base 1, and the side of the base 1 is the surface of the base 1 in the first direction. In this way, the sewage discharge outlet 620 of the sewage discharge section 62 can be formed on the side of the base 1, that is, the surface of the base 1 in the first direction. The sewage discharge outlet 620 is used to connect to 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, and the overall pipeline installation is convenient, which is also conducive to reducing the occupied volume of the cleaning base station 10 of the present disclosure. In addition, because the sewage discharge outlet 620 is located on the side of the base 1, and the side of the base 1 is the surface of the base 1 in the first direction, it is convenient to make the sewage discharge section 62 and the external extension pipe connected to the sewage discharge outlet 620 of the base consistent in extension direction, effectively reducing the kinetic energy loss of dirt during the sewage discharge process, and sewage discharge is smoother.

[0125] like Figure 3 As shown, in one embodiment of the present disclosure, the cleaning base station 10 also includes a contraction portion 34, the second portion 312 is connected to the contraction portion 34, the contraction portion 34 is connected to the sewage pipe 6, and the sewage pipe 6 forms a sewage outlet connected to the sewer on the side of the cleaning base station 10, and the contraction portion 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 portion 34 is greater than the slope of the inner wall surface of the second portion 312.

[0126] Specifically, the sewage pipe 6 is connected to the bottom outlet of the sewage trough 3 through the constriction 34. The area of ​​the bottom outlet of the sewage trough 3 is larger than the area of ​​the outlet of the sewage pipe 6. The constriction 34 is vertically arranged within the base station, and its cross-sectional area gradually decreases from top to bottom, thereby connecting the bottom outlet of the sewage trough 3 with the sewage pipe 6 with a smaller outlet. The slope of the curved surface of the constriction 34 is greater than the slope of the curved surface of the second portion 312, allowing dirt falling from the bottom outlet of the sewage trough 3 to fall directly onto the outlet of the sewage pipe 6, minimizing the probability of dirt landing on the wall of the constriction 34 and reducing potential energy loss. The contraction portion 34 causes the passage from point B to the pipe opening of the sewage pipe 6 to pass through two different arc surfaces and contract gradually, rather than directly contracting smoothly from point B to the pipe opening of the sewage pipe 6. This increases the volume of the lower part, which is beneficial to reducing the thickness of the base station. The slope of the two arc surfaces gradually increases, which is beneficial to allowing dirt to fall directly to the pipe opening of the sewage pipe 6, increasing the smoothness of sewage discharge and avoiding potential energy loss caused by dirt colliding with the arc surface.

[0127] like Figure 5 As shown, the cleaning base station disclosed herein further includes a sewage discharge assisting device 70 , the output port 701 of which is configured to be set at a position corresponding to the connecting section 61 , and is configured to provide a pressure source at least to the area of ​​the connecting section 61 through the output port 701 .

[0128] In order to prevent solid dirt in the dirt from being deposited in the sewage discharge section 62 and causing blockage of the sewage pipe 6, the sewage discharge assisting device 70 can provide a pressure source to at least the area of ​​the connecting section 61 through the output port 701, thereby increasing the flow speed of dirt in the sewage discharge section 62 of the sewage pipe 6, and preventing solid dirt in the dirt from being deposited in the sewage discharge section 62 and causing blockage of the sewage pipe 6. This not only ensures that the cleaning base station 10 of the present disclosure can normally discharge the dirt in the cleaning equipment 90 to the sewer and other external environments, but also prevents the sewage pipe 6 from being blocked, avoiding the need for users to manually clean the blocked sewage pipe 6, effectively reducing the user's usage burden and improving the user's usage experience.

[0129] In one embodiment of the present disclosure, the sewage discharge assisting device 70 is configured to provide a positive pressure source to the area of ​​the connecting section 61. Specifically, when the sewage discharge assisting device 70 provides a positive pressure source to the area of ​​the connecting section 61, it can accelerate the flow of sewage within the connecting section 61 of the sewage pipe 6, thereby accelerating the flow of sewage along the sewage section 62 of the sewage pipe 6 as quickly as possible and discharging it to the outside world. It is understood that when the sewage discharge assisting device 70 provides a positive pressure source to the area of ​​the connecting section 61, it can be located within the connecting section 61 or at the rear of the connecting section 61 in the direction of sewage flow, such as within the sewage trough 3.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] Specifically, such as Figure 5 As shown, in one embodiment of the present disclosure, the sewage discharge assisting device 70 is a jet assembly 7, which includes a jet component 72 having a jet outlet 71. The jet component 72 is configured to discharge a pressurized fluid through the jet outlet 71; the opening direction of the jet outlet 71 is configured to face a first direction, and the fluid discharged from the jet outlet 71 flows along the first direction. That is, during the operation of the jet assembly 7, the jet component 72 of the jet assembly 7 can discharge a pressurized fluid from the jet outlet 71 in the first direction, and the pressurized fluid can flow along the first direction, pushing the dirt to accelerate the flow in the connecting section 61 of the sewage pipe 6, thereby accelerating the flow along the sewage discharge section 62 of the sewage pipe 6 as quickly as possible to be discharged to the outside.

[0136] It is understandable that if a jet component is added to an existing cleaning base station to assist in sewage discharge, since the jet component is directly opposite the sewage outlet on the back of the base station, the distance from the jet component to the sewage outlet is very short, and the water flow ejected by the jet component is blocked by the bend of the sewage outlet of the base station, it is difficult to play the role of assisting sewage discharge. In the cleaning base station disclosed herein, since the jet component 72 of the jet assembly 7 can flow pressurized fluid from the jet outlet 71 in the first direction, the pressurized fluid will not be blocked after being ejected, extending the assist path of the pressurized fluid and maximizing the role of assisting sewage discharge.

[0137] It is understandable that if Figure 5 As shown, the pressurized fluid can be a pressurized liquid. After flowing into the jet inlet, the pressurized liquid can be collected into the dirt in the connecting section 61 and, under the action of its own kinetic energy, push the dirt along the drainage section 62 toward the outlet of the drainage section 62. In another embodiment of the present disclosure, the pressure source can also be a pressurized gas. The pressurized gas can also push the dirt along the drainage section 62 toward the outlet of the drainage section 62 under the action of its own gas pressure. The principle is similar and will not be repeated here.

[0138] Specifically, such as Figure 5 As shown, in one embodiment of the present disclosure, a pipe joint 630 is provided on the side of the connecting section 61 opposite to the sewage discharge section 62; the jet component 72 is configured to be installed in the pipe joint 630, and the jet outlet 71 is configured to face the direction of the connecting section 61 and the sewage discharge section 62. That is, during the processing of the connecting section 61, it is necessary to process the pipe joint 630 on the side of the connecting section 61 opposite to the sewage discharge section 62; when the jet component 72 is installed, it is installed in the pipe joint 630, and the jet outlet 71 is configured to face the direction of the connecting section 61 and the sewage discharge section 62. This ensures that after the pressurized fluid flows out of the jet outlet 71, it can flow along the pipe joint 630 toward the side where the sewage discharge section 62 is located, thereby pushing the dirt to flow along the sewage discharge section 62 toward the outlet of the sewage discharge section 62.

[0139] Further, such 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 constructed to be installed in the sleeve 63; the bottom of the sleeve 63 is constructed to be higher than the bottom of the sewage discharge section 62, and the top of the sleeve 63 is constructed to be lower than the top of the sewage discharge section 62.

[0140] 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 component 72 is installed in the sleeve 63, it can ensure 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 discharge pipe 6 and push the dirt along the rear section of the connecting section 61 to flow toward the sewage discharge section 62; the pressurized fluid will not impact the inner cavity wall or other positions of the connecting section 61, thereby effectively avoiding the waste of kinetic energy of the pressurized fluid, thereby improving the effect of the jet component 7 in pushing the flow of dirt and preventing the dirt from clogging the sewage discharge pipe 6.

[0141] Further, such as Figure 5 As shown, in one embodiment of the present disclosure, the sleeve 63 is constructed to extend from the inner wall of the connecting section 61 in a direction away from the sewage discharge section 62, and the opening of the sleeve 63 on the inner wall of the connecting section 61 is configured to match the shape of the inner wall of the connecting section 61. Since the sleeve 63 extends from the inner wall of the connecting section 61 in a direction away from the sewage discharge section 62, and the opening of the sleeve 63 on the inner wall of the connecting section 61 matches the shape of the inner wall of the connecting section 61, the sleeve 63 does not extend into the interior of the connecting section 61, and the flow of dirt along the connecting section 61 is not hindered by the sleeve 63, thereby ensuring that the dirt can flow smoothly along the connecting section 61 and, in the process of flowing through the opening of the sleeve 63, is accelerated by the pressurized fluid to flow toward the sewage discharge section 62.

[0142] like Figure 5 As shown, in one embodiment of the present disclosure, a fluid pipeline connected to the jet component 72 is provided on the base 1, and the fluid is configured to flow into the jet component 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 component 72 through the fluid pipeline, and then flow out from the jet outlet 71 of the jet component 72. It is understandable that the fluid can be a medium fluid such as tap water or cleaning liquid, which can come from an external water source such as a tap, or from a water tank or cleaning liquid tank inside the base station. The power source device can be a water pump or other related device, which is not limited here.

[0143] In another embodiment of the present disclosure, a fluid conduit is provided on the base 1 and is connected to the jet element 72. The fluid conduit is configured to be connected to a water faucet. The fluid in the water faucet is configured to flow into the jet element 72 through the fluid conduit under the action of its own water pressure. It is understood that since the water faucet has its own water pressure, when the fluid conduit is connected to the water faucet, the fluid in the water faucet can flow into the jet element 72 through the fluid conduit under the action of its own water pressure, and then flow out of the jet outlet 71 of the jet element 72.

[0144] like Figure 5 As shown, in one embodiment of the present disclosure, the jet component 72 includes a jet tube 721, and the jet outlet 71 is arranged on the end surface of the jet tube 721; the jet component 72 also includes a venturi tube 722 located in the jet tube 721, and the fluid is constructed to be discharged from the jet outlet 71 after passing through the venturi tube 722.

[0145] That is, during the operation of the jet assembly 7, when the pressurized fluid of the jet assembly 7 flows into the jet tube 721 of the jet element 72, it flows through the venturi tube 722 within the jet tube 721, and is then discharged from the jet outlet 71. After flowing through the venturi tube 722, the pressurized fluid can have a high flow rate and good stability. In particular, if the total flow area of ​​the jet outlet 71 is smaller than the minimum flow cross-section of the venturi tube 722, the wastewater jet can achieve a higher flow rate, thereby improving the efficiency of the pressurized fluid in accelerating the waste.

[0146] like Figure 5 As shown, in one embodiment of the present disclosure, the jet member 72 is constructed to be located on a side of the connecting section 61 opposite to the sewage discharge section 62, and the opening direction of the jet outlet 71 is constructed to be toward the extension direction of the sewage discharge section 62; the jet outlet 71 at least partially overlaps with the inner cavity of the sewage discharge section 62 in the height direction.

[0147] Since the jet component 72 is located on the side of the connecting section 61 opposite to the sewage discharge section 62, and the opening direction of the jet outlet 71 is toward the extension direction of the sewage discharge section 62; the jet outlet 71 at least partially overlaps with the inner cavity of the sewage discharge section 62 in the height direction, it can be ensured that the pressurized fluid output by the jet component 7 can flow along the extension direction of the sewage discharge section 62 toward the direction of the sewage discharge section 62 after flowing out of the jet outlet 71, thereby impacting the dirt in the connecting section 61 and directly pushing the dirt to flow along the rear section of the connecting section 61 toward the sewage discharge 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.

[0148] like 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 minimized from rotating in the sewage discharge section 62, thereby allowing the dirt to be discharged from the sewage discharge section 62 as quickly as possible.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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.

[0153] Similar, such as Figure 5As shown, in one embodiment of the present disclosure, the bottom end of the jet outlet 71 is constructed 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 of the jet outlet 71, the fluid located at the lower 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 lower than the bottom end of the inner cavity of the sewage discharge section 62. This can also effectively avoid wasting 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 clogging the sewage discharge pipe 6.

[0154] like Figure 13 and Figure 14 As shown, in one embodiment of the present disclosure, a plurality of jet outlets 71 are provided, and the plurality of jet outlets 71 are configured to be evenly arranged on the end surface of the jet member 72. Since a plurality of jet outlets 71 are provided and the plurality of jet outlets 71 are evenly arranged on the end surface of the jet member 72, the pressurized fluid flowing out of each jet outlet 71 can jointly push the dirt, so that the force-bearing surface of the dirt in the sewage pipe 6 is larger and the force is more balanced. This can enable dirt at all circumferential locations to be pushed toward the outlet of the sewage pipe 6 by the thrust from the pressurized fluid, thereby avoiding the situation where only part of the dirt is accelerated while other parts are not, resulting in solid dirt in the dirt being deposited in the sewage pipe 6.

[0155] Specifically, such as Figure 13 and Figure 14 As shown, in one embodiment of the present disclosure, the jet outlet 71 includes a central outlet 711 located at the center of the jet member 72 and an edge outlet 712 provided at the edge of the jet member 72. At least two edge outlets 712 are provided, located on at least two 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 portion of the dirt in the sewage pipe 6, and the pressurized fluid ejected from the edge outlet 712 can impact the circumferential edge portion of the dirt in the sewage pipe 6, thereby ensuring that the dirt at the central position and the edge position in the sewage pipe 6 can be pushed and accelerated by the pressurized fluid, so that the force on the dirt in the sewage pipe 6 is more balanced, which is conducive to the flow of dirt and prevents solid dirt in the dirt from being deposited in the sewage pipe 6.

[0156] like 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] 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.

[0164] 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.

[0165] like Figures 10 to 12As shown, in one embodiment of the present disclosure, the cleaning base station 10 includes a self-cleaning component 5 located in the sewage trough 3, and the self-cleaning component 5 is constructed to be located at a position higher than the end face of the sewage receiving port 321; the self-cleaning component 5 is constructed to output cleaning liquid to the inner cavity of the sewage receiving part 31 and / or the sewage receiving part 32.

[0166] In this way, during the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning equipment 90 is discharged into the sewage trough 3 and discharged from the sewage pipe 6, the self-cleaning component 5 can output cleaning liquid to the inner cavity of the sewage receiving part 31 and / or the sewage holding part 32, thereby cleaning the inner wall of the sewage receiving part 31 and / or the sewage holding part 32, and preventing dirt from remaining on the inner wall of the sewage receiving part 31 and / or the sewage holding part 32. Moreover, since the sewage trough 3 mainly uses the sewage holding part 32 to receive the dirt from the cleaning equipment 90, the self-cleaning component 5 is located at a position higher than the end face of the sewage holding port 321, and the sewage holding part 32 is lower than the sewage receiving part 31. When the self-cleaning component 5 cleans the sewage trough 3, it can fully clean the sewage holding part 32, and prevent the occurrence of cleaning dead corners in the sewage trough 3.

[0167] like Figure 10 As shown, in one embodiment of the present disclosure, the self-cleaning component 5 is located at the top of the sewage trough 3, and the self-cleaning component 5 is configured to output cleaning liquid from the top of the sewage receiving part 31 to the inner cavity of the sewage receiving part 31, and output cleaning liquid from the top of the sewage receiving part 31 to the top of the sewage holding part 32 and the inner cavity of the sewage holding part 32. In this way, during the operation of the cleaning base station 10 of the present disclosure, the dirt discharged by the cleaning device 90 is discharged into the sewage trough 3 and discharged from the sewage pipe 6. The self-cleaning component 5 can output cleaning liquid from the top of the sewage receiving part 31 to the inner cavity of the sewage receiving part 31, and output cleaning liquid from the top of the sewage receiving part 31 to the top of the sewage holding part 32 and the inner cavity of the sewage holding part 32, thereby cleaning the inner cavities of the sewage receiving part 31 and the sewage holding part 32, preventing dirt from remaining in the inner cavities of the sewage receiving part 31 and the sewage holding part 32, and ensuring that the sewage trough 3 of the present disclosure is clean and odorless, thereby effectively improving the user experience.

[0168] Moreover, since the self-cleaning component 5 can output cleaning liquid from the top of the dirt holding portion 31 to the inner cavity of the dirt holding portion 31 and the inner cavity of the dirt receiving portion 32, there is no need to set up separate cleaning mechanisms for the dirt holding portion 31 and the dirt receiving portion 32, which can effectively simplify the water channel structure of the cleaning base station 10 disclosed in the present invention and promote the miniaturization of the cleaning base station 10 disclosed in the present invention.

[0169] like Figure 10 、 Figure 15 、 Figure 16 、 Figure 20As shown, in one embodiment of the present disclosure, the self-cleaning component 5 includes a dirt-containing cleaning member 51, a dirt-containing cleaning member 52 and a liquid inlet pipe 53. The dirt-containing cleaning member 51 is arranged at the top of the inner cavity of the dirt-containing portion 31, and is constructed to output cleaning liquid to the inner cavity of the dirt-containing portion 31. The dirt-containing cleaning member 52 is arranged at the top of the inner cavity of the dirt-containing portion 32, and is constructed to output cleaning liquid to the inner cavity of the dirt-containing portion 32; the liquid inlet pipe 53 is connected to the dirt-containing cleaning member 51 and the dirt-containing cleaning member 52, and the cleaning liquid flowing into the liquid inlet pipe 53 is constructed to partially flow into the dirt-containing cleaning member 51 and partially flow to the dirt-containing cleaning member 52.

[0170] In this way, during the operation of the cleaning base station 10 of the present disclosure, the cleaning liquid flowing into the liquid inlet pipe 53 is constructed to partially flow into the dirt-containing cleaning part 51 and partially flow into the dirt-holding cleaning part 52. The cleaning liquid flowing into the dirt-holding cleaning part 51 can output the cleaning liquid from the top of the inner cavity of the dirt-holding part 31 to the inner cavity of the dirt-holding part 31, thereby cleaning the inner cavity of the dirt-holding part 31. The cleaning liquid flowing into the dirt-holding cleaning part 52 can output the cleaning liquid from the top of the inner cavity of the dirt-holding part 32 to the inner cavity of the dirt-holding part 32, thereby cleaning the inner cavity of the dirt-holding part 31. In this way, only one liquid inlet pipe 53 is required to provide cleaning liquid to the dirt-holding cleaning part 51 and the dirt-holding cleaning part 52 at the same time, thereby effectively simplifying the waterway structure of the cleaning base station 10 of the present disclosure.

[0171] Specifically, such as Figure 10 As shown, in one embodiment of the present disclosure, a liquid inlet cavity 54 connected to the liquid inlet pipe 53 is provided on the outer wall of the top of the dirt holding portion 31; wherein, the dirt holding cleaning member 51 is constructed to be arranged at a position corresponding to the liquid inlet cavity 54 and connected to the liquid inlet cavity 54; the dirt holding 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 to the inner cavity of the dirt holding portion 32; the liquid inlet section 522 is configured to connect the liquid inlet cavity 54 and the liquid discharge section 521.

[0172] 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 chamber 54, part of the cleaning liquid in the liquid inlet chamber 54 will flow into the dirt-containing cleaning member 51, and the remaining cleaning liquid in the liquid inlet chamber 54 will flow along the liquid inlet section 522 to the liquid discharge section 521, thereby achieving the purpose of simultaneously providing cleaning liquid to the dirt-containing cleaning member 51 and the liquid discharge section 521. The overall liquid inlet structure is simple and the flow of the cleaning liquid is relatively smooth.

[0173] like Figure 10As shown, in one embodiment of the present disclosure, a cover plate 55 is provided on the outer wall of the dirt-receiving portion 31. The cover plate 55 is fastened to the outer wall of the dirt-receiving portion 31 and, together with the outer wall of the dirt-receiving portion 31, forms a liquid inlet cavity 54. The liquid inlet pipe 53 is provided on the cover plate 55. In this way, the liquid inlet cavity 54 is formed by fastening the cover plate 55 on the outer wall of the dirt-receiving portion 31 to the dirt-receiving portion 31. Moreover, the liquid inlet pipe 53 is provided on the cover plate 55 and can be directly connected to the liquid inlet cavity 54 without the need for other connecting pipes, thereby further simplifying the liquid inlet structure.

[0174] Specifically, such as Figure 10 As shown, in one embodiment of the present disclosure, a through hole 56 is provided on the outer wall of the dirt-receiving portion 31 at a position corresponding to the liquid inlet cavity 54. The liquid inlet cavity 54 is configured to communicate with the dirt-receiving cleaning member 51 through the through hole 56. In this way, after the cleaning liquid flows from the liquid inlet pipe 53 into the liquid inlet cavity 54, it can flow through the through hole 56 to the dirt-receiving cleaning member 51, that is, to the top of the inner cavity of the dirt-receiving portion 31, thereby cleaning the inner cavity of the dirt-receiving portion 31.

[0175] like Figure 10 As shown, in one embodiment of the present disclosure, the dirt-containing portion 31 includes a first portion 311 located at the top and a second portion 312 located at the bottom, and the first portion 311 is configured to dock with the second portion 312; the size of the first portion 311 is configured to have a gradually expanding structure with the cross-sectional area increasing from top to bottom; the dirt-containing cleaning member 51 is arranged at the center position of the inner cavity of the first portion 311 of the dirt-containing portion 31, and is configured to output cleaning liquid radially to all sides.

[0176] Since the first portion 311 located at the top of the dirt-receiving portion 31 has a gradually expanding structure with an increasing cross-sectional area from top to bottom, the dirt-receiving cleaning member 51 is arranged at the center of the inner cavity of the first portion 311 of the dirt-receiving portion 31. When the dirt-receiving cleaning member 51 outputs cleaning liquid radially in all directions, it can clean all circumferential locations of the inner cavity of the dirt-receiving portion 31, avoiding the occurrence of cleaning dead corners in the dirt-receiving portion 31.

[0177] like Figure 9 As shown, in one embodiment of the present disclosure, the top of the dirt-receiving portion 32 is constructed to extend outward from the dirt-receiving portion 31 to form a dirt-receiving port 321 for docking with the dirt outlet 93 of the cleaning device 90. The dirt-receiving cleaning member 52 is constructed to at least partially surround the circumferential sidewalls of the dirt-receiving port 321 and is configured to output cleaning liquid from at least a portion of the circumference of the dirt-receiving port 321. In this way, because the dirt-receiving cleaning member 52 at least partially surrounds the circumferential sidewalls of the dirt-receiving port 321 and outputs cleaning liquid from at least a portion of the circumference of the dirt-receiving port 321, the dirt-receiving cleaning member 52 can clean at least a portion of the circumferential sidewalls of the dirt-receiving portion 32, reducing the amount of dirt remaining on the circumferential sidewalls of the dirt-receiving portion 32 and reducing the odor caused by the dirt residue in the cleaning base station 10 of the present disclosure.

[0178] Specifically, such as Figure 7 As shown, in one embodiment of the present disclosure, the dirt-receiving portion 32 includes an enclosing wall 322 away from the side of the dirt-containing portion 31, and the enclosing wall 322 is constructed to extend obliquely downward from the top of the dirt-receiving portion 32 to dock with the corresponding position of the dirt-containing portion 31; the dirt-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, and the first side wall 323, the second side wall 324, and the enclosing wall 322 are constructed to enclose the dirt-receiving portion 32 on the dirt-containing portion 31; the dirt-receiving cleaning member 52 is constructed to be located on the top of the first side wall 323, the second side wall 324, and the enclosing wall 322, and is constructed to output cleaning liquid downward from the top of the first side wall 323, the second side wall 324, and the enclosing wall 322.

[0179] In this way, the dirt-receiving cleaning component 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, thereby ensuring that the dirt-receiving cleaning component 52 can clean the first side wall 323, the second side wall 324, and the enclosing wall 322 of the dirt-receiving part 32, avoiding dirt from remaining on the first side wall 323, the second side wall 324, and the enclosing wall 322 of the dirt-receiving part 32, and trying to avoid the odor formed by the dirt residue of the cleaning base station 10 disclosed in the present invention.

[0180] Further, such as Figure 7 As shown, in one embodiment of the present disclosure, the end surface of the sewage receiving port 321 is configured to extend horizontally or obliquely downward from the location where it connects to the sewage receiving portion 31; the sewage receiving cleaning member 52 is configured to be arranged along the end surface of the sewage receiving port 321. Since the sewage receiving cleaning member 52 is arranged along the end surface of the sewage receiving port 321, the cleaning liquid output by the sewage receiving cleaning member 52 can flow downward from the end surface of the sewage receiving port 321, avoiding the formation of cleaning dead corners in the sewage receiving portion 32.

[0181] like Figures 10 to 12 As shown, in one embodiment of the present disclosure, the sewage trough 3 includes a sewage receiving portion 32 having a sewage receiving port 321, and the sewage receiving port 321 is configured to be used for docking with the sewage outlet 93 of the cleaning equipment 90; the sewage receiving cleaning member 52 is arranged around the sewage receiving port 321, and is constructed to output cleaning liquid to the inner cavity of the sewage receiving portion 32; the sewage receiving cleaning member 52 includes a liquid inlet section 522 and a liquid discharge section 521, and the liquid discharge section 521 is constructed to be connected to 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 to the liquid discharge section 521 through the liquid inlet section 522, and is configured to flow to the inner cavity of the sewage receiving portion 32 through the liquid discharge section 521.

[0182] Thus, 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 is discharged from the sewage outlet 321 of the sewage receiving part 32 into the sewage trough 3 and then discharged from the sewage pipe 6. Then, the dirt-receiving 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 dirt-receiving cleaning member 52 is arranged around the sewage outlet 321, the dirt-receiving cleaning member 52 can clean the inner cavity of the sewage receiving part 32 when outputting the cleaning liquid, preventing dirt from remaining in the inner cavity of the sewage receiving part 32, ensuring that the interior of the sewage receiving part 32 of the present disclosure is clean and odor-free, thereby effectively improving the user experience.

[0183] Moreover, since the dirt-carrying cleaning component 52 includes a liquid inlet section 522 and a liquid discharge section 521, the liquid discharge section 521 is connected to 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 flow to the inner cavity of the dirt-carrying part 32 through the liquid discharge section 521. There is no need for external power to supply power to the flow of the cleaning liquid, thereby eliminating the power source required for the dirt-carrying cleaning component 52, thereby effectively simplifying the water channel structure of the cleaning base station 10 disclosed in the present invention and promoting the miniaturization of the cleaning base station 10 disclosed in the present invention.

[0184] Further, such as Figure 12 As shown, in one embodiment of the present disclosure, the two ends of the liquid inlet section 522 are respectively connected to the two ends of the liquid discharge section 521, and the liquid inlet section 522 and the liquid discharge section 521 are constructed to form an annular structure. Since the two ends of the liquid inlet section 522 are respectively connected to the two ends of the liquid discharge section 521, the liquid inlet section 522 and the liquid discharge section 521 form an annular structure, and the cleaning liquid entering the liquid inlet section 522 will be divided into two parts, flowing to the two ends of the liquid discharge section 521 respectively, and then flowing along the liquid discharge section 521 until it flows to the middle of the liquid discharge section 521, and in the process of the cleaning liquid flowing along the liquid discharge section 521, part of it will flow out from the liquid discharge section 521 to the inner cavity of the dirt holding part 32, thereby cleaning the inner cavity of the dirt holding part 32. Since the cleaning liquid flows into the liquid discharge section 521 from both ends, not only is the required path for the cleaning liquid the shortest, the flow time is the shortest, but the water pressure loss of the cleaning liquid is also the least.

[0185] like Figure 7 and Figure 12As shown, in one embodiment of the present disclosure, the pollution-receiving portion 32 includes an enclosing wall 322, and the enclosing wall 322 is constructed to extend obliquely downward from the top of the pollution-receiving portion 32 to form a pollution discharge surface 325. The pollution-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 constructed to enclose the pollution-receiving portion 32; the drainage section 521 is constructed to extend along the top of the first side wall 323, the enclosing wall 322, and the second side wall 324, and the cleaning liquid is configured to flow out from the position of the drainage section 521 corresponding to the first side wall 323, the enclosing wall 322, and the second side wall 324. Since the drainage section 521 extends along the top of the first side wall 323, the enclosing wall 322, and the second side wall 324, the cleaning liquid flows out from the positions of the drainage section 521 corresponding to the first side wall 323, the enclosing wall 322, and the second side wall 324. After the cleaning liquid flows out from the positions of the drainage section 521 corresponding to the first side wall 323, the enclosing wall 322, and the second side wall 324, the first side wall 323, the enclosing wall 322, and the second side wall 324 can be cleaned, thereby avoiding dirt from remaining on the first side wall 323, the second side wall 324, and the enclosing wall 322 of the dirt receiving part 32, and trying to avoid the odor formed by the dirt residue of the cleaning base station 10 disclosed in the present invention.

[0186] like Figure 9 As shown, in one embodiment of the present disclosure, the sewage trough 3 includes a sewage receiving portion 31 located in the base 1, a sewage receiving portion 32 is arranged on the side wall of the sewage receiving portion 31 and is in communication with the inner cavity of the sewage receiving portion 31, and the top of the sewage receiving portion 32 is configured to be lower than the top of the sewage receiving portion 31; a liquid discharge section 521 is configured to be arranged at the top of the sewage receiving portion 32, and a liquid inlet section 522 is configured to be arranged at a position adjacent to the sewage receiving portion 32 on the sewage receiving portion 31. Since the top of the sewage receiving portion 32 is lower than the top of the sewage receiving portion 31, the liquid discharge section 521 is arranged at the top of the sewage receiving portion 32, and the liquid inlet section 522 is arranged at a position adjacent to the sewage receiving portion 32 on the sewage receiving portion 31, the cleaning liquid can flow naturally from a position adjacent to the sewage receiving portion 32 on the sewage receiving portion 31 to the liquid discharge section 521 at the top of the sewage receiving portion 32 under the action of its own gravity, without the need for external power to supply power to the flow of the cleaning liquid, thereby eliminating the power source required for the sewage receiving cleaning member 52.

[0187] like Figure 12As shown, in one embodiment of the present disclosure, a liquid inlet cavity 54 is provided at the top of the dirt-receiving portion 31. The liquid inlet cavity 54 is configured to communicate with the middle of the liquid inlet section 522. The cleaning liquid in the liquid inlet cavity 54 is configured to flow from the middle of the liquid inlet section 522 to both sides thereof. A diverter plate 523 is provided in the flow path from the liquid inlet cavity 54 to the liquid inlet section 522. The cleaning liquid in the liquid inlet cavity 54 is configured to flow to both sides of the liquid inlet section 522 via both sides of the diverter plate 523. In this way, the cleaning liquid in the liquid inlet cavity 54 can flow from the middle of the liquid inlet section 522 via both sides of the diverter plate 523 to both sides of the liquid inlet section 522 under the blocking effect of the diverter plate 523, thereby naturally achieving the purpose of diverting the cleaning liquid to both ends of the liquid inlet section 522.

[0188] like Figure 10 As 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 gravity of the cleaning liquid itself can be used 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 external power to flow the cleaning liquid, thereby eliminating the power source required for the dirt-carrying cleaning component 52.

[0189] Specifically, such as Figure 12 As shown, in one embodiment of the present disclosure, the liquid inlet section 522 is higher than the liquid discharge section 521, and both ends of the liquid inlet section 522 are configured to extend downward along the wall of the dirt-receiving portion 31 to communicate with both ends of the liquid discharge section 521. Because both ends of the liquid inlet section 522 extend downward along the wall of the dirt-receiving portion 31 to communicate with both ends of the liquid discharge section 521, cleaning liquid entering the liquid inlet section 522 can be naturally split into two parts, flowing downward along the wall of the dirt-receiving portion 31 to both ends of the liquid discharge section 521, thereby automatically providing cleaning liquid to both ends of the liquid discharge section 521.

[0190] like Figure 10 and Figure 12 、 Figure 21 As shown, in one embodiment of the present disclosure, the liquid discharge section 521 includes a guide groove 5211 extending circumferentially along the dirt-receiving portion 32, and a guide plate 5212 covering the guide groove 5211. The guide plate 5212 and the guide groove 5211 on one side adjacent to the inner cavity of the dirt-receiving portion 32 form an overflow port 5213. The cleaning liquid flowing in the guide groove 5211 is configured to flow into the inner cavity of the dirt-receiving portion 32 through the overflow port 5213. That is, the guide groove 5211 is formed between the guide plate 5212 and the dirt-receiving portion 32, and the guide plate 5212 and the guide groove 5211 on one side adjacent to the inner cavity of the dirt-receiving portion 32 form the overflow port 5213. In this way, during the process of the cleaning liquid flowing along the guide groove 5211, a portion of the cleaning liquid can continue to flow from the overflow port 5213 into the inner cavity of the dirt-receiving portion 32, thereby cleaning the inner cavity of the dirt-receiving portion 32.

[0191] Furthermore, after the cleaning liquid entering from both ends of the drainage section 521 converges in the middle of the drainage section 521, it will also flow from the corresponding overflow port 5213 into the inner cavity of the dirt-receiving portion 32 to clean the inner cavity of the dirt-receiving portion 32. Since the overflow port 5213 is formed on the side of the guide plate 5212 and the guide groove 5211 adjacent to the inner cavity of the dirt-receiving portion 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 portion 32 corresponding to the guide groove 5211 can be cleaned, avoiding the occurrence of cleaning blind spots and preventing dirt from remaining in the inner cavity of the dirt-receiving portion 32.

[0192] Specifically, in one embodiment of the present disclosure, the guide groove 5211 is provided on the outer side of the inner wall of the sewage receiving portion 32, and the guide plate 5212 on the side facing the inner cavity of the sewage receiving portion 32 is configured to extend from the top of the sewage receiving portion 32 toward the inner cavity of the sewage receiving portion 32 to form an overflow port 5213 with the top end surface of the sewage receiving portion 32. Figure 10 and Figure 12 As shown, the guide groove 5211 is arranged on the radially outer side of the inner wall of the pollution-receiving part 32, and the guide plate 5212 extends from the top of the pollution-receiving part 32 toward the inner cavity of the pollution-receiving part 32 on the side facing the inner cavity of the pollution-receiving part 32, so as to form an overflow port 5213 with the top end face of the pollution-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 pollution-receiving part 32, it can flow out from the overflow port 5213 opened at the top of the guide groove 5211 toward the inner cavity of the pollution-receiving part 32, and then flow into the pollution-receiving part 32 to clean the pollution-receiving part 32.

[0193] It is understandable that if Figure 10 and Figure 12 As shown, the radial 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 of the radial outer side of the guide groove 5211; in another embodiment of the present disclosure, the guide plate 5212 and the outer wall surface of the dirt receiving portion 32 can also be enclosed to form the guide groove 521. Figure 10 As shown, in one embodiment of the present disclosure, the guide groove 5211 is arranged on the outer side of the inner wall of the sewage receiving part 32, and the side of the guide plate 5212 facing the inner cavity of the sewage receiving part 32 is constructed to form a downward bending portion, and the bending portion and the inner wall of the sewage receiving part 32 form an overflow port 5213 with an opening facing downward.

[0194] That is Figure 10As shown, the guide groove 5211 is arranged on the radial outside of the dirt holding part 32, and the radial outside of the guide plate 5212 is sealed with the outside of the guide groove 5211, which can prevent the cleaning liquid from flowing out from the radial outside of the guide groove 5211; the radial inside of the guide plate 5212 forms a downward bending portion, and the bending portion and the inner wall of the dirt holding part 32 form an overflow port 5213 with an opening facing downward and toward the inner cavity of the dirt holding part 32. In this way, after the liquid level of the cleaning liquid in the guide groove 5211 exceeds the top end surface of the dirt holding part 32, it will flow to the inside of the bending portion, and then The cleaning liquid flows out from the overflow port 5213 under the blocking effect of the overflow port 5213, which can ensure that the cleaning liquid flows downward from the top of the inner cavity of the dirt-receiving part 32 along the inner wall of the dirt-receiving part 32, and because the guide plate 5212 and the guide groove 5211 are arranged on the outside rather than the inside of the inner wall of the dirt-receiving part 32, the overflow port 5213 will not protrude from the inner wall of the dirt-receiving part 32, avoiding the formation of a dead angle below the connection position between the overflow port 5213 and the inner wall of the dirt-receiving part 32, so that the cleaning liquid can clean all the inner walls of the dirt-receiving part 32, avoiding the occurrence of cleaning dead angles in the dirt-receiving part 32.

[0195] like Figure 12 As shown, in one embodiment of the present disclosure, at least two spaced apart support portions 5214 are provided between the guide plate 5212 and the top end surface of the dirt receiving portion 32, and the guide plate 5212 is at least configured to be supported on the support portions 5214. Thus, the support portions 5214 support the guide portion, ensuring that an overflow opening 5213 can be formed between the guide plate 5212 and the top end surface of the dirt receiving portion 32, thereby preventing deformation of the guide plate 5212 and partial blockage of the overflow opening 5213, which could prevent the cleaning liquid from flowing normally.

[0196] It is understandable that the guide plate 5212 and the cover plate 55 forming the liquid inlet cavity 54 may be fixedly connected or integrally formed, which is not limited here.

[0197] like Figure 10 、 Figure 15 and Figure 16 As shown, in one embodiment of the present disclosure, the cleaning base station 10 of the present disclosure further includes a dirt-containing cleaning member 51, which is arranged at the top of the inner cavity of the dirt-containing portion 31 and is constructed to form a liquid outlet channel 511 with the top wall of the dirt-containing portion 31. The cleaning liquid flowing out of the liquid outlet channel 511 is configured to flow downward at least along the inner wall of the dirt-containing portion 31.

[0198] Thus, 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 drain trough 3 and discharged from the drain pipe 6, the dirt-receiving cleaning member 51 can output cleaning liquid from the top of the dirt-receiving portion 31 to the inner cavity of the dirt-receiving portion 31, thereby cleaning the inner cavity of the dirt-receiving portion 31 and preventing dirt from remaining in the inner cavity of the dirt-receiving portion 31, ensuring that the drain trough 3 of the present disclosure is clean and odor-free, thereby effectively improving the user experience. Moreover, since the dirt-receiving cleaning member 51 is arranged at the top of the inner cavity of the dirt-receiving portion 31 and forms a liquid outlet channel 511 with the top wall of the dirt-receiving portion 31, the cleaning liquid flowing out of the liquid outlet channel 511 flows downwardly along the top wall of the dirt-receiving portion 31, thereby ensuring that the dirt-receiving cleaning member 51 can clean the top of the inner cavity of the dirt-receiving portion 31, reducing the cleaning dead angles in the dirt-receiving portion 31, especially eliminating the cleaning dead angles at the top of the dirt-receiving portion 31, thereby reducing the dirt remaining in the inner cavity of the dirt-receiving portion 31.

[0199] like Figure 10 and Figure 15 As shown, in one 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-receiving cleaning member 51, and is configured to output the cleaning liquid for cleaning the inner wall of the dirt-receiving cavity in the circumferential direction of the dirt-receiving cleaning member 51. In this way, the cleaning liquid can be output outward from the circumference of the dirt-receiving cleaning member 51, and because the dirt-receiving cleaning member 51 is arranged at the top of the inner cavity of the dirt-receiving portion 31, the cleaning liquid can be output outward from the circumferential top of the inner cavity of the dirt-receiving portion 31, thereby ensuring that the cleaning liquid can clean all circumferential locations of the inner cavity of the dirt-receiving portion 31, avoiding the occurrence of cleaning dead corners in the dirt-receiving portion 31, especially at the top of the dirt-receiving portion 31, preventing dirt from remaining in the inner cavity of the dirt-receiving portion 31, and ensuring that the dirt-receiving portion 31 of the present disclosure is clean and odorless.

[0200] Specifically, such as Figure 10 As shown, in one embodiment of the present disclosure, the dirt-receiving portion 31 includes a first portion 311 located at the top and a second portion 312 located at the bottom. The first portion 311 is configured to interface with the second portion 312. The first portion 311 is configured to have a gradually expanding structure with a larger cross-sectional area from top to bottom. The dirt-receiving cleaning member 51 is disposed at the center of the inner cavity of the first portion 311 of the dirt-receiving portion 31 and is configured to output cleaning liquid along the circumference of the dirt-receiving cleaning member 51. Because the size of the first portion 311 located at the top of the dirt-receiving portion 31 is configured to have a gradually expanding structure with a larger cross-sectional area from top to bottom, when the dirt-receiving cleaning member 51, disposed at the center of the inner cavity of the first portion 311 of the dirt-receiving portion 31, outputs cleaning liquid along the circumference of the dirt-receiving cleaning member 51, it is ensured that the cleaning liquid at all circumferential locations can flow down along the inner wall of the dirt-receiving portion 31 to clean all circumferential locations of the inner cavity of the dirt-receiving portion 31, further avoiding the occurrence of cleaning dead corners within the dirt-receiving portion 31.

[0201] Specifically, such as Figure 10As shown, in one embodiment of the present disclosure, the end surface of the dirt-receiving cleaning member 51 adjacent to the top wall of the dirt-receiving portion 31 is configured to form a liquid outlet channel 511 with the top wall of the dirt-receiving portion 31; and the circumferential edge of the dirt-receiving cleaning member 51 is configured to form a liquid outlet of the liquid outlet channel 511. In this way, cleaning liquid flows from the through-hole 56 on the top wall of the dirt-receiving portion 31 into the liquid outlet channel 511 formed by the end surface of the dirt-receiving cleaning member 51 adjacent to the top wall of the dirt-receiving portion 31 and the top wall of the dirt-receiving portion 31. It is then discharged outward along the circumferential edge of the dirt-receiving cleaning member into the inner cavity of the dirt-receiving portion 31, resulting in a relatively simple overall water channel structure.

[0202] Specific examples Figure 15 and Figure 16 As shown, in one embodiment of the present disclosure, at least two partitions 512 are provided on the end face of the dirt-containing cleaning member 51, and at least two partitions 512 abut against the top wall of the dirt-containing portion 31; and / or, at least two partitions 512 are provided on the top wall of the dirt-containing portion 31, and at least two partitions 512 abut against the end face of the dirt-containing cleaning member 51; the partitions 512 make the end face of the dirt-containing cleaning member 51 and the top wall of the dirt-containing portion 31 enclose a liquid outlet channel 511, and the partitions 512 are constructed to be arranged at intervals in the circumferential direction of the liquid outlet channel 511.

[0203] That is, the partition 512 is disposed on one of the end surface of the dirt-receiving cleaning member 51 or the top wall of the dirt-receiving portion 31, and abuts the other. Because the partitions 512 are spaced apart in the circumferential direction of the liquid outlet channel 511, the partitions 512 form the liquid outlet channel 511 between the end surface of the dirt-receiving cleaning member 51 and the top wall of the dirt-receiving portion 31, and form a guide area 5111 within the liquid outlet channel 511, thereby allowing the cleaning liquid to flow within the guide area 5111 formed by the partition 512.

[0204] Specifically, such as Figure 15 As shown, in one embodiment of the present disclosure, the partition 512 is configured to extend in the radial direction of the liquid outlet channel 511; the two side walls of the partition 512 are configured to intersect in the direction adjacent to the liquid outlet and constitute the first end of the partition 512. Since the partition 512 extends in the radial direction of the liquid outlet channel 511, and the two side walls of the partition 512 intersect in the direction adjacent to the liquid outlet and constitute the first end of the partition 512, that is, Figure 15 As shown, the partition 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 512 flows along the two walls of the partition 512, an intersection area will be generated. Cleaning liquid will flow outward along the entire circumference of the dirt-containing cleaning part 51, and no cleaning dead corner will be generated due to the existence of the partition 512.

[0205] It can be understood that the extension of the partition 512 in the radial direction of the liquid outlet channel 511 refers to the extension from the center of the dirt-receiving cleaning member 51 to the surrounding areas. Figure 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.

[0206] 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.

[0207] 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.

[0208] 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.

[0209] 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.

[0210] In one embodiment of the present disclosure, the cleaning base station 10 of the present disclosure further includes an elastic member. The dirt-receiving cleaning member 51 is configured to be pre-pressed against the top wall of the dirt-receiving portion 31 by the elastic member. The dirt-receiving cleaning member 51 is configured to move away from the top wall of the dirt-receiving portion 31 when subjected to an external force greater than a threshold value, and to move toward the top wall of the dirt-receiving portion 31 under the action of the elastic member when subjected to an external force less than a 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 low, the dirt-receiving cleaning member 51 can be moved toward the top wall of the dirt-receiving portion 31 under the elastic force of the elastic member, thereby pressing against the top wall of the dirt-receiving portion 31 to block the top wall of the dirt-receiving portion 31. Furthermore, when the water pressure of the cleaning liquid decreases, the dirt-receiving cleaning member 51 can be moved toward the top wall of the dirt-receiving portion 31 under the elastic force of the elastic member, thereby narrowing the liquid outlet channel 511, maintaining continuous flow through the liquid outlet channel 511 and maintaining a certain liquid outlet pressure during liquid discharge, thereby improving the flushing effect of the dirt-receiving cleaning member 51.

[0211] When the water pressure of the cleaning liquid flowing out of the through hole 56 is relatively large and exceeds 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 in the direction away from the top wall of the dirt-containing portion 31, and naturally open the liquid outlet channel 511, so that the cleaning liquid can be continuously output at various locations along the circumference of the dirt-containing cleaning member 51, so as to ensure that the water pressure of the cleaning liquid for cleaning the dirt-containing portion 31 is relatively high, thereby meeting the cleaning requirements.

[0212] like Figure 7 and Figure 10 As shown, in one embodiment of the present disclosure, the sewage trough 3 includes a sewage receiving portion 32 that is in communication with the inner cavity of the sewage receiving portion 31. The sewage receiving port 321 provided at the top of the sewage receiving portion 32 is constructed to be lower than the top of the sewage receiving portion 31. A baffle 33 is provided on the side of the sewage receiving portion 31 adjacent to the sewage receiving portion 32. The baffle 33 is constructed to extend downward from the top wall of the sewage receiving portion 31 to a position adjacent to the sewage receiving port 321. Since the baffle 33 is provided on the side of the sewage receiving portion 31 adjacent to the sewage receiving portion 32 and extends downward from the top wall of the sewage receiving portion 31 to a position adjacent to the sewage receiving port 321, the cleaning liquid output by the sewage receiving cleaning member 51 can be prevented from flowing to the inner wall of the sewage receiving portion 32 and interfering with the cleaning liquid output by the sewage receiving cleaning member 52, and the cleaning liquid can also be prevented from being splashed out of the sewage receiving port 321.

[0213] like Figure 3 As shown, in one embodiment of the present disclosure, the cleaning base station 10 of the present disclosure further includes a blockage sensor 8, which is arranged at a detection position 81 of the sewage trough 3, and the blockage sensor 8 is configured to be triggered when sewage blockage occurs at the detection position 81; wherein, the volume below the detection position 81 in the cleaning base station 10 is constructed to be greater than 80% of the volume of the sewage bucket 92.

[0214] Specifically, the blockage sensor 8 is usually a light sensor, including a light emitting end and a light receiving end. When liquid flows through the end face of the blockage sensor 8, the light emitted from the light emitting end is refracted and cannot be reflected back to the light receiving end, thereby triggering the detection of a liquid signal.

[0215] Assuming that the wastewater bucket 92 of cleaning equipment 90 is full and there is no blockage in drain chute 3, the time required to drain from drain chute 3 is t1. During this time t1 required for this drainage process, dirt will continue to flow through blockage sensor 8. The maximum continuous time that blockage sensor 8 senses the liquid signal is t1. When a blockage occurs in drain chute 3 and the blockage water level reaches blockage sensor 8, blockage sensor 8 detects the liquid signal. If the continuous time that liquid level sensor 8 detects the liquid signal exceeds t1, it is determined that a blockage has occurred.

[0216] In existing cleaning base stations, the volume of the sewage trough 3 below the detection position 81 is relatively small. When the amount of sewage discharged is large, the dirt is easily accumulated at the detection position 81, but in fact no blockage has occurred, so a false alarm will occur. During the operation of the cleaning base station 10 disclosed in the present invention, 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 will dock with the sewage receiving port 321 on the sewage trough 3, and the dirt in the sewage bucket 92 will flow into the sewage trough 3. Since the blockage sensor 8 is arranged in the sewage trough 3 and can be triggered when the liquid level of the dirt in the sewage trough 3 reaches the detection position 81, when the cleaning base station 10 disclosed in the present invention is blocked, causing the liquid level of the dirt in the sewage trough 3 to reach the detection position 81, the blockage sensor 8 can be triggered in time, which facilitates the cleaning base station 10 disclosed in the present invention to accelerate sewage discharge, thereby removing the dirt blocked in the sewage pipe 6, or performing other subsequent steps.

[0217] 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 easy to accumulate at the detection position 81, thereby effectively avoiding false alarms.

[0218] Furthermore, in one embodiment of the present disclosure, the volume of the sewage chute 3 above the detection position 81 is configured to be larger than the volume of the sewage bucket 92 .

[0219] Among them, after the cleaning device 90 starts to discharge sewage, due to the blockage of the cleaning base station 10, the sewage in the sewage trough 3 cannot be discharged smoothly. When the sewage level reaches the detection position 81, the blockage sensor 8 can be triggered in time, which facilitates the cleaning base station 10 to process. After the cleaning device 90 starts to discharge sewage, due to the blockage of the cleaning base station 10, the sewage in the sewage trough 3 cannot be discharged smoothly. The blockage sensor 8 will not be triggered until the sewage level reaches the detection position 81. After the cleaning device 90 discharges sewage again, the sewage in the sewage trough 3 continues to accumulate. As a result, the blockage sensor 8 will not be triggered until the sewage level reaches the detection position 81. However, the sewage discharge process of the cleaning device 90 will not stop, but will continue until the sewage bucket 92 is emptied. At this time, since the volume of the sewage trough 3 above the detection position 81 is larger than the volume of the sewage bucket 92, even at the end of the first sewage discharge, the sewage trough 3 has not reached the detection position 81 and has not triggered the blockage sensor 8. During the second sewage discharge, the sewage trough 3 can continue to accommodate all the dirt in the sewage bucket 92, and the dirt will not overflow from the sewage bucket 92, thereby preventing the dirt from overflowing from the sewage trough 3 and polluting the cleaning base station 10, effectively reducing the user's usage burden and improving the user's usage experience.

[0220] Specifically, in one embodiment of the present disclosure, the sewage trough 3 includes a sewage receiving portion 31 and a sewage holding portion 32 connected to the inner cavity of the sewage receiving portion 31; the detection position 81 is located in the inner cavity of the sewage receiving portion 31; wherein, the volume above the detection position 81 includes the portion of the sewage receiving portion 31 located above the detection position 81, and the portion of the sewage holding portion 32 located above the detection position 81. It is understandable that the portion of the sewage receiving portion 31 located above the detection position 81 and the portion of the sewage holding portion 32 located above the detection position 81 can both be used to temporarily store sewage, thereby preventing sewage from overflowing from the sewage trough 3 and contaminating the cleaning base station 10 in the event of a blockage in the cleaning base station 10, and effectively reducing the required volume in the sewage trough 3, thereby facilitating the miniaturization of the cleaning base station 10 of the present disclosure.

[0221] Specifically, such as Figure 7 As shown, in one embodiment of the present disclosure, the top of the dirt-receiving portion 32 is configured to extend outward from the dirt-receiving portion 31 to form a dirt-receiving port 321. The opening direction of the dirt-receiving port 321 is configured to face upward and is configured to be connected to the sewage outlet 93 of the cleaning device 90. The volume above the detection position 81 includes the dirt-receiving portion 31 and the portion of the dirt-receiving portion 32 located from the detection position 81 to the dirt-receiving port 321. Because the volume above the detection position 81 includes the dirt-receiving portion 31 and the portion of the dirt-receiving portion 32 located from the detection position 81 to the dirt-receiving port 321, if a blockage occurs in the cleaning base station 10, it can prevent dirt from overflowing from the dirt-receiving port 321 of the dirt-receiving portion 32 and contaminating the cleaning base station 10.

[0222] like Figure 7 As shown, in one embodiment of the present disclosure, the top end surface of the sewage receiving port 321 is configured to be lower than the top of the sewage receiving portion 31. In the case where the top end surface of the sewage receiving port 321 is lower than the top of the sewage receiving portion 31, the detection position 81 can be set below the top end surface of the sewage receiving port 321, and the volume meets the above requirements to ensure that the blockage sensor 8 can be normally triggered when a blockage occurs.

[0223] like Figure 4 and Figure 7 As shown, in one embodiment of the present disclosure, the dirt-receiving portion 32 is connected to one side of the dirt-containing portion 31, and the dirt-receiving portion 32 has a dirt discharge surface 325 extending to communicate with the inner cavity of the dirt-containing portion 31, and at least part of the dirt flowing out of the dirt discharge port 93 is constructed to flow from the dirt discharge surface 325 to the inner cavity of the dirt-containing portion 31; the detection position 81 is constructed to be arranged on a side of the dirt-containing portion 31 away from the dirt discharge surface 325.

[0224] Thus, during operation of the cleaning base station 10 of the present disclosure, the discharge surface 325 of the dirt receiving portion 32 can receive dirt discharged from the discharge port 93 of the cleaning device 90 and direct the dirt discharged by the cleaning device 90 into the inner cavity of the dirt receiving portion 31. Since the detection position 81 is located on a side of the dirt receiving portion 31 away from the discharge surface 325, dirt flowing along the discharge surface 325 is less likely to impact the clogging sensor 8 at the detection position 81, thereby reducing the probability of false alarms from the clogging sensor 8.

[0225] Furthermore, in one embodiment of the present disclosure, the detection position 81 is configured to be no lower than the bottom end of the drainage surface 325. When dirt flows along the drainage surface 325 of the dirt receiving portion 32 into the inner cavity of the dirt receiving portion 31, because the detection position 81 is no lower than the bottom end of the drainage surface 325, the dirt will not directly impact the clogging sensor 8 at the detection position 81 during the process of flowing into the inner cavity of the dirt receiving portion 31, even if the flow speed is relatively fast, thereby effectively preventing the clogging sensor 8 from false alarms.

[0226] In one embodiment of the present disclosure, the volume of the sewage trough 3 above the detection position 81 is configured to be larger than the volume of the sewage trough 3 below the detection position 81. Since the volume of the sewage trough 3 above the detection position 81 is configured to be larger than the volume of the sewage trough 3 below the detection position 81, it can be ensured that the volume of the sewage trough 3 above the detection position 81 can meet the requirements. Under the premise that dirt overflows from the sewage trough 3 and contaminates the cleaning base station 10, the required volume of the sewage trough 3 is reduced, thereby facilitating the miniaturization of the cleaning base station 10 of the present disclosure.

[0227] In another embodiment of the present disclosure, the volume of the cleaning base station 10 below the detection position 81 is 0.8 to 1.2 times the volume of the sewage bucket 92. Since the volume of the sewage trough 3 below the detection position 81 is 0.8 to 1.2 times the volume of the sewage bucket 92, and since it takes some time for the cleaning base station 10 of the present disclosure to discharge the dirt, the portion of the sewage trough 3 below the detection position 81 can temporarily store the dirt during the discharge process of the cleaning base station 10 of the present disclosure, ensuring that the dirt from the cleaning equipment 90 is quickly discharged into the sewage trough 3. If the cleaning base station 10 is not blocked, the dirt level will not reach the detection position 81, and the blockage sensor 8 will not be triggered. This prevents the dirt level from reaching the detection position 81 during each sewage discharge process, causing the blockage sensor 8 to falsely alarm. It can be understood that the volume of the cleaning base station 10 below the detection position 81 includes not only the portion of the sewage trough 3 below the detection position 81, but also the volume of the sewage pipe 6.

[0228] In one embodiment of the present disclosure, the control unit of the present disclosure is configured to issue an alarm based on the electrical signal triggered by the clogging sensor 8. In this way, when the clogging sensor 8 is triggered, the control unit can promptly issue an alarm, thereby notifying the user to perform maintenance or other work.

[0229] In one embodiment of the present disclosure, if the blockage sensor 8 detects a blockage, self-cleaning is canceled, a prompt is given, and charging is performed. In another embodiment of the present disclosure, if a blockage occurs, the jet element can be operated for a period of time (e.g., 3 seconds, during which time it can operate at the original water flow rate or at an increased water flow rate, thereby increasing the kinetic energy of flushing). This period of time is related to the volume of the drain tank above the blockage sensor (900 ml) and the flow rate of the jet element (8L / min to 15L / min). Water cannot overflow, and a period of time is waited (e.g., 5 seconds, as it takes a certain amount of time for the blocked dirt to drain away). If the drain tank is still blocked, self-cleaning is canceled, a prompt is given, and charging is performed.

[0230] It is understood that when the cleaning base station 10 of the present disclosure is provided with the aforementioned jet assembly 7, the cleaning base station 10 of the present disclosure controls the jet assembly 7 to operate for a period of time while issuing an alarm message to accelerate the flow of dirt in the sewage pipe 6 to flush away the dirt clogged in the sewage pipe 6. However, if the blockage is more serious and cannot be flushed away, the user can only clean it manually.

[0231] In one embodiment of the present disclosure, the drain chute 3 is provided with a sewage receiving port 321 for docking with the sewage outlet 93 of the cleaning device 90; and the drain chute 3 is constructed to rotate between a first position and a second position. When the sewage receiving port 321 is in the first position, it is located in front 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 dock with the cleaning base station 10 for sewage discharge, the drain chute 3 can be rotated to the first position, and the sewage outlet 93 of the cleaning device 90 can dock with the sewage receiving port 321 of the drain chute 3, and the dirt in the cleaning device 90 can be discharged into the cleaning base station 10 through the sewage receiving port 321; and when sewage discharge is not required, the drain chute 3 can be rotated to the second position, so that the sewage receiving port 321 is stored in the base 1, thereby hiding the sewage receiving port 321, preventing the sewage chute 3 from having a odor, and effectively improving the user experience. Specifically, the rotation of the drain chute 3 can be controlled by a motor or other mechanical transmission device. The specific principle can be referred to other existing technologies and will not be repeated here. In another embodiment, the rotation of the drain chute 3 can also be achieved by docking the cleaning device 90 with 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 the first trigger member, causing the first trigger member to change from the initial state to the first state, thereby driving the drain chute 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 drain chute 3 to rotate to the second position.

[0232] In one embodiment of the present disclosure, the sewage trough 3 is provided with a sewage receiving port 321 for docking with the sewage outlet 93 of the cleaning device 90. 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 thereto.

[0233] 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 outlet 321 of the sewage trough 3, and the dirt in the cleaning device 90 can be discharged into the cleaning base station 10 through the sewage outlet 321; and when sewage discharge is not required, the sewage outlet 321 can be closed by using the partition, thereby hiding the sewage outlet 321, and also preventing the sewage trough 3 from having a odor, thereby effectively improving the user experience. Specifically, the movement of the partition can be controlled by using a structure such as a motor or other mechanical transmission device. The specific principle can be referred to other existing technologies and will not be repeated here. In another embodiment, the movement of the partition can also be achieved by docking the cleaning device 90 with the cleaning base station 10. Specifically, a second trigger can be set on the base station 10, and the second trigger 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 an initial state to a 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.

[0234] like Figure 10 As shown, in one embodiment of the present disclosure, the sewage trough 3 includes a sewage holding portion 31, which includes a gradually expanding portion whose cross-sectional area gradually increases from top to bottom and a gradually contracting portion whose cross-sectional area gradually decreases from top to bottom. The gradually expanding portion is connected to the top of the gradually contracting portion, and the detection position 81 is located at the junction of the bottom end of the gradually expanding portion and the gradually contracting portion. That is, the detection position 81 is located at the junction of the bottom end of the first portion 311 and the contracting portion, which can increase the volume below the detection position 81 when blockage occurs and reduce the probability of false alarms when the water discharge speed is slow. At the same time, since the junction of the bottom end of the gradually expanding portion and the gradually contracting portion of the sewage holding portion 31 is very obvious, it is convenient for workers to install the blockage sensor 8, and there is no need to locate the detection position 81 before installation.

[0235] like Figures 1 to 3 As shown, the present disclosure further 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 .

[0236] Application Scenario 1

[0237] The present disclosure provides a cleaning base station 10, which is used to perform cleaning work in conjunction with a cleaning device 90. The cleaning base station 10 includes a base 1, a tray 2 and a drain chute 3; the base 1 is constructed to extend in the height direction, and is used to install various functional elements required for the cleaning base station 10, such as the drain chute 3. The tray 2 is arranged at the bottom of the base 1, and extends horizontally toward the front side relative to the base 1, and the side opposite to the front side is recorded as the rear side. The drain chute 3 includes a dirt-receiving portion 31 located in the cleaning base station 10 and a dirt-receiving portion 32 connected to the inner cavity of the dirt-receiving portion 31; the dirt-receiving portion 32 is located on the front side of the dirt-receiving portion 31, and is constructed to be connected to the side wall of the dirt-receiving portion 31 to enclose a receiving cavity with the dirt-receiving portion 31.

[0238] During operation of the cleaning base station 10 of the present disclosure, the cleaning device 90 is placed on the tray 2, and the sewage outlet 93 of the cleaning device 90 is located above the sewage receiving portion 32, and the sewage discharged by the cleaning device 90 can be discharged into the sewage trough 3. The sewage receiving 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. It is mainly used to receive the sewage discharged by the cleaning device 90 and guide the sewage discharged by the cleaning device 90 into the sewage receiving portion 31; the sewage receiving portion 31 is set in the base 1, mainly used to temporarily store sewage and guide the sewage discharged by the cleaning device 90 into the sewage pipe 6 so that the sewage is discharged to the outside.

[0239] Since the dirt-receiving portion 32 is located in front of the dirt-receiving portion 31 and is connected to the side wall of the dirt-receiving portion 31, protruding from the base 1 toward the front, and the dirt-receiving portion 31 is located within the base 1, the layout of the cleaning base station 10 of the present disclosure can be effectively optimized, saving space, and facilitating the miniaturization of the cleaning base station 10. Moreover, when the sewage trough 3 becomes clogged, the dirt-receiving portion 32 and the sewage-receiving portion 31 can jointly accommodate the dirt to prevent the dirt from overflowing from the sewage trough 3. Compared to the existing cleaning base station 10, the overall volume of the sewage trough 3 of the cleaning base station 10 of the present disclosure is larger and occupies less space, effectively improving the user experience.

[0240] Application Scenario 2

[0241] The present disclosure provides a cleaning base station 10, which is used to perform cleaning work in conjunction with a cleaning device 90. Specifically, the cleaning base station 10 includes a base 1, a tray 2, a drain trough 3 and a drain pipe 6; the base 1 is constructed to extend in the height direction; the tray 2 is located at the bottom of the base 1 and is constructed to extend in the horizontal direction, and a roller brush groove 21 is provided on the tray 2 for accommodating a roller brush of the cleaning device 90, with the axial direction of the roller brush groove 21 as the first direction; the drain trough 3 is provided on the cleaning base station 10; the drain pipe 6 is constructed to be connected to the bottom of the drain trough 3; the drain pipe 6 has at least a drain section 62 extending in the transverse direction, and a connecting section 61 connecting the drain section 62 with the bottom of the drain trough 3, one end of the connecting section 61 is constructed to extend toward the bottom of the drain trough 3 until it is connected to the bottom of the drain trough 3, and the other end is constructed to extend toward the drain section 62 until it is connected to the drain section 62; the drain section 62 extends along the first direction.

[0242] 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 trough 3 in the base 1. The dirt will flow from the bottom of the sewage trough 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 along the first direction, the sewage section 62 can be effectively arranged using the entire width of the cleaning base station 10, thereby reducing the overall length of the cleaning base station 10 in the second direction of the present disclosure. In addition, since the sewage section 62 extends along the first direction, the dirt only needs to go through the connecting section 61 once when flowing to the sewage section 62. The sewage section 62 is consistent with the extension direction of the external extension pipe connected to the sewage outlet of the base station, thereby effectively reducing the kinetic energy loss of the dirt during the sewage discharge process, and the sewage discharge is smoother.

[0243] Application Scenario 3

[0244] The present disclosure provides a cleaning base station 10, comprising a base 1, a tray 2 and a sewage trough 3, wherein the base 1 is constructed to extend in the height direction; the tray 2 is located at the bottom of the base 1 and is constructed to extend in the horizontal direction; the side of the base 1 on which the tray 2 is provided is recorded as the front side, and the side opposite thereto is recorded as the rear side; the sewage trough 3 comprises a sewage receiving portion 31 located in the base station and a sewage receiving portion 32 connected to the inner cavity of the sewage receiving portion 31; the sewage receiving portion 32 is constructed to have a sewage receiving port 321 for docking with the sewage outlet 93 of the cleaning equipment 90; the sewage receiving portion 32 has a sewage discharge surface 325, and at least part of the dirt flowing in from the sewage receiving port 321 is constructed to be guided from the sewage discharge surface 325 to the inner cavity of the sewage receiving portion 31; the area on the sewage discharge surface 325 corresponding to the sewage outlet 93 is constructed to be a flat surface or a continuous smooth curved surface.

[0245] During 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 portion 32, and the dirt discharged by the cleaning device 90 can be discharged into the sewage trough 3. Among them, the sewage surface 325 of the sewage receiving portion 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 sewage receiving portion 31, that is, at least part of the dirt flowing out of the sewage outlet 93 can flow from the sewage surface 325 to the inner cavity of the sewage receiving portion 31; the sewage receiving portion 31 is arranged in the base 1, mainly for temporarily storing dirt, and guiding the dirt discharged by the cleaning device 90 into the sewage pipe 6, so that the dirt is discharged to the outside. Specifically, since the area on the sewage discharge surface 325 corresponding to the sewage outlet 93 is constructed as a flat surface or a continuous smooth curved surface, the dirt will flow downward smoothly when it falls from the sewage outlet 321 to the sewage discharge surface 325, ensuring that the dirt continues to flow to the sewage pipe 6 with greater kinetic energy. It can also prevent the dirt from splashing out of the sewage outlet 321 when it falls on the sewage discharge surface 325 and falling onto the base 1 or tray 2 of the cleaning base station 10. There is no need for the user to perform secondary cleaning of the cleaning base station 10, which effectively reduces the user's usage burden and improves the user's usage experience.

[0246] Application Scenario 4

[0247] The present disclosure provides a cleaning base station 10, which is used to perform cleaning work in conjunction with a cleaning device 90. Specifically, the cleaning base station 10 includes a base 1, a drain trough 3 and a self-cleaning component 5; the base 1 is constructed to extend in the height direction; the drain trough 3 includes a dirt-receiving portion 31 located in the base 1 and a dirt-receiving portion 32 connected to the inner cavity of the dirt-receiving portion 31, and the dirt-receiving portion 32 is constructed to be connected to the side wall of the dirt-receiving portion 31; the self-cleaning component 5 is located at the top of the drain trough 3, and the self-cleaning component 5 is constructed to output cleaning liquid from the top of the dirt-receiving portion 31 to the inner cavity of the dirt-receiving portion 31, and to output cleaning liquid from the top of the dirt-receiving portion 31 to the top of the dirt-receiving portion 32 and the inner cavity of the dirt-receiving portion 32.

[0248] During the operation of the cleaning base station 10 of the present disclosure, the dirt discharged by the cleaning device 90 is discharged into the drain trough 3 and discharged from the drain pipe 6. The self-cleaning component 5 can output cleaning liquid from the top of the dirt holding part 31 to the inner cavity of the dirt holding part 31, and output cleaning liquid from the top of the dirt holding part 31 to the top of the dirt holding part 32 and the inner cavity of the dirt holding part 32, thereby cleaning the inner cavities of the dirt holding part 31 and the dirt holding part 32, preventing dirt from remaining on the inner cavities of the dirt holding part 31 and the dirt holding part 32, and ensuring that the drain trough 3 of the present disclosure is clean and odorless, thereby effectively improving the user experience. Moreover, since the self-cleaning component 5 can output cleaning liquid from the top of the dirt holding part 31 to the inner cavities of the dirt holding part 31 and the dirt holding part 32, there is no need to set up a separate cleaning mechanism for the dirt holding part 31 and the dirt holding 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.

[0249] Application Scenario 5

[0250] The present disclosure provides a cleaning base station 10, which is used to perform cleaning work in conjunction with a cleaning device 90. Specifically, the cleaning base station 10 includes a base 1, a drain trough 3 and a dirt-receiving cleaning member 52; the base 1 is constructed to extend in the height direction; the drain trough 3 includes a dirt-receiving portion 32 having a dirt-receiving port 321, and the dirt-receiving port 321 is configured to dock with the dirt-receiving port 93 of the cleaning device 90; the dirt-receiving cleaning member 52 is arranged around the dirt-receiving port 321, and is constructed to output cleaning liquid to the inner cavity of the dirt-receiving portion 32; the dirt-receiving cleaning member 52 includes a liquid inlet section 522 and a liquid discharge section 521, and the liquid discharge section 521 is constructed to be connected to 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 to the liquid discharge section 521 through the liquid inlet section 522, and is configured to flow to the inner cavity of the dirt-receiving portion 32 through the liquid discharge section 521.

[0251] Thus, 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 is discharged from the sewage outlet 321 of the sewage receiving part 32 into the sewage trough 3 and then discharged from the sewage pipe 6. Then, the dirt-receiving 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 dirt-receiving cleaning member 52 is arranged around the sewage outlet 321, the dirt-receiving cleaning member 52 can clean the inner cavity of the sewage receiving part 32 when outputting the cleaning liquid, preventing dirt from remaining in the inner cavity of the sewage receiving part 32, ensuring that the interior of the sewage receiving part 32 of the present disclosure is clean and odor-free, thereby effectively improving the user experience.

[0252] Moreover, since the dirt-carrying cleaning component 52 includes a liquid inlet section 522 and a liquid discharge section 521, the liquid discharge section 521 is connected to 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 flow to the inner cavity of the dirt-carrying part 32 through the liquid discharge section 521. There is no need for external power to supply power to the flow of the cleaning liquid, thereby eliminating the power source required for the dirt-carrying cleaning component 52, thereby effectively simplifying the water channel structure of the cleaning base station 10 disclosed in the present invention and promoting the miniaturization of the cleaning base station 10 disclosed in the present invention.

[0253] Application Scenario 6

[0254] The present disclosure provides a cleaning base station 10, which is used to perform cleaning work in conjunction with a cleaning device 90. Specifically, the cleaning base station 10 includes a base 1, a drain trough 3 and a dirt-receiving cleaning member 51; the base 1 is constructed to extend in the height direction; the drain trough 3 includes a dirt-receiving portion 31 located in the base 1; the dirt-receiving cleaning member 51 is arranged at the top of the inner cavity of the dirt-receiving portion 31, and is constructed to form a liquid outlet channel 511 with the top wall of the dirt-receiving portion 31, and the cleaning liquid flowing out of the liquid outlet channel 511 is configured to flow downward at least along the inner wall of the dirt-receiving portion 31.

[0255] In this way, during the operation of the cleaning base station 10 of the present invention, the dirt discharged by the cleaning equipment 90 is discharged into the sewage trough 3 and discharged from the sewage pipe 6. The dirt-containing cleaning member 51 can output cleaning liquid from the top of the sewage-containing part 31 to the inner cavity of the sewage-containing part 31, thereby cleaning the inner cavity of the sewage-containing part 31 and preventing dirt from remaining on the inner cavity of the sewage-containing part 31, ensuring that the sewage trough 3 of the present invention is clean and odor-free, thereby effectively improving the user experience.

[0256] Moreover, since the dirt-containing cleaning member 51 is arranged at the top of the inner cavity of the dirt-containing portion 31 and forms a liquid outlet channel 511 with the top wall of the dirt-containing portion 31, the cleaning liquid flowing out of the liquid outlet channel 511 flows downward at least along the inner wall of the dirt-containing portion 31, thereby ensuring that the dirt-containing cleaning member 51 can clean the top of the inner cavity of the dirt-containing portion 31, reducing the cleaning dead corners in the dirt-containing portion 31, and thus reducing the residual dirt in the inner cavity of the dirt-containing portion 31.

[0257] Application Scenario 7

[0258] The present disclosure provides a cleaning base station 10, which is configured to be docked with a cleaning device 90 and includes a base 1, a drain chute 3 and a blockage sensor 8. The base 1 is configured to extend in a height direction; the drain chute 3 is provided with a sewage receiving port 321 for docking with a sewage outlet 93 of the cleaning device 90; the blockage sensor 8 is provided at a detection position 81 of the drain chute 3, and the blockage sensor 8 is configured to be triggered when a sewage blockage occurs at the detection position 81; wherein the volume within 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.

[0259] During 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 outlet 93 of the cleaning device 90 will dock with the sewage receiving port 321 on the sewage trough 3, and the dirt in the sewage bucket 92 will flow into the sewage trough 3. Since the blockage sensor 8 is disposed in the sewage trough 3 and can be triggered when the liquid level of the dirt in the sewage trough 3 reaches the detection position 81, when the cleaning base station 10 of the present disclosure is blocked and the liquid level of the dirt in the sewage trough 3 reaches the detection position 81, the blockage sensor 8 can be triggered in time, facilitating the cleaning base station 10 of the present disclosure to accelerate sewage discharge, thereby removing the dirt blocked in the sewage pipe 6, or performing other subsequent steps.

[0260] 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 easy to accumulate at the detection position 81, thereby effectively avoiding false alarms.

[0261] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terms used herein are selected to best explain the principles of the embodiments, their practical applications, or technical improvements in the marketplace, or to enable other persons skilled in the art to understand the embodiments disclosed herein. The scope of the present disclosure is defined by the appended claims.
