Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, specifically to a cleaning base station; this disclosure also relates to a cleaning system. Background Technology

[0002] Environmental sanitation is a crucial factor affecting quality of life. Therefore, as people's demands for quality of life continue to rise, so too do their requirements for environmental sanitation. This has led to the development of various floor cleaning devices, commonly including vacuum cleaners, sweepers, and floor scrubbers. A floor scrubber is a cleaning machine that simultaneously cleans the floor, vacuums up wastewater, and removes the wastewater from the site.

[0003] Existing floor scrubbers typically have a solution tank for storing cleaning solutions and a wastewater tank for collecting wastewater after cleaning. To empty the wastewater from the wastewater tank, the user needs to manually remove the lid and drain the wastewater through the top opening of the tank. This operation is laborious, and the user may come into contact with dirt, significantly impacting the user experience.

[0004] Therefore, a cleaning system with a cleaning base station has emerged on the market. By working with the cleaning base station, the floor scrubber can discharge the wastewater in its internal wastewater tank. Some cleaning base stations can also clean the cleaning components of the floor scrubber, such as the rags.

[0005] However, the overall layout of existing cleaning base stations is not reasonable. In order to connect with cleaning equipment, they occupy a lot of space, which can easily lead to wasted space.

[0006] In existing cleaning base stations, a guide section is typically installed above the dirt-holding section, which connects to the drain outlet of the cleaning equipment's recycling bin. The dirt-holding section is a hemispherical shape that tapers from top to bottom. When blockage occurs, dirt fills the dirt-holding section from bottom to top. Because the bottom volume of the dirt-holding section is very small, the radial dimension above the dirt-holding section needs to be very large to achieve sufficient dirt holding capacity. Simultaneously, because the guide section is located above the dirt-holding section, both the guide section and the dirt-holding section are limited in height when the guide section needs to connect to the bottom of the cleaning machine's recycling bin. Furthermore, the spaces of the guide section and the dirt-holding section are independent; the guide section primarily serves only a guiding function and cannot effectively contain dirt when blockage occurs. Therefore, the existing technology results in a large drainage tank, a large space occupied by the base station, and a small blockage capacity, severely impacting the user experience.

[0035] According to a second aspect of this disclosure, a cleaning system is provided, comprising:

[0036] A cleaning device, comprising a body and a drain outlet disposed on the body;

[0037] The aforementioned clean base station.

[0038] This disclosure provides a cleaning base station for use with cleaning equipment to perform cleaning operations. The cleaning base station includes a base, a tray, and a drain trough; the base is configured to extend in the height direction and is used to install various functional components required for the cleaning base station, such as the drain trough.

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

[0073] This disclosure provides a cleaning base station for use with cleaning equipment to perform cleaning operations. The cleaning base station includes a base, a tray, and a drain trough; the base is configured to extend in the height direction and is used to install various functional components required for the cleaning base station, such as the drain trough. The tray is disposed at the bottom of the base and extends forward horizontally relative to the base, with the side opposite to the front side referred to as the rear side. The drain trough includes a dirt-containing portion located within the cleaning base station and a dirt-receiving portion communicating with the inner cavity of the dirt-containing portion; the dirt-receiving portion is located in front of the dirt-containing portion and is configured to connect to the side wall of the dirt-containing portion to form a receiving cavity with the dirt-containing portion.

[0074] During the operation of the cleaning base station disclosed herein, the cleaning equipment is placed on a tray, with its drain outlet located above the dirt-receiving part, and the dirt discharged by the cleaning equipment can be discharged into a drain trough. The dirt-receiving part is located in front of the dirt-holding part and connected to its side wall; it primarily receives the dirt discharged by the cleaning equipment and guides it into the dirt-holding part. The dirt-holding part is located within the base and primarily serves to temporarily store the dirt and guide it into a drain pipe for discharge to the outside.

[0075] Because the contaminant-collecting part is located on the front side of the contaminant-holding part and connected to the side wall of the contaminant-holding part, protruding forward from the base, and the contaminant-holding part is located inside the base, the layout of the cleaning base station of this disclosure can be effectively optimized, saving space and facilitating the miniaturization of the cleaning base station. Furthermore, when the drain trough becomes clogged, the contaminant-collecting part and the contaminant-holding part can jointly contain the dirt, preventing dirt from overflowing from the drain trough. Compared to existing cleaning base stations, the overall volume of the drain trough of the cleaning base station of this disclosure is larger, occupying less space, effectively improving the user experience.

[0076] For ease of understanding, please refer to the following: Figures 1 to 24 The specific structure and working principle of the cleaning base station 10 of this disclosure are described in detail with reference to one embodiment. It should be noted that this disclosure also provides a cleaning base station 10. To keep the text concise, the cleaning system is also described in conjunction with the cleaning base station 10.

[0077] like Figures 1 to 6 As shown, this disclosure provides a cleaning base station 10, which is used in conjunction with cleaning equipment 90 to perform cleaning work.

[0078] 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 connected to each other so that the cleaning device 90 can discharge sewage into the cleaning base station 10. In addition, the cleaning base station 10 can also charge the cleaning device 90, replenish cleaning fluid, etc., which will not be described in detail here.

[0079] Specifically, such as Figure 1 and Figure 2 As shown, the cleaning device 90 includes at least a body 91 and a wastewater tank 92. It can be understood that the cleaning device 90 may also include a floor brush assembly 94 and a cleaning solution tank. The body 91 serves as a carrier for mounting various functional components required by the cleaning device 90.

[0080] The floor brush assembly 94 is located at the bottom of the body 91 and is used to clean work surfaces such as floors, carpets, or furniture surfaces. A pivot can be installed between the floor brush assembly 94 and the body 91, allowing the body 91 to rotate relative to the floor brush assembly 94. When the body 91 rotates backward to an inclined position away from the floor brush assembly 94, the user can easily drag the cleaning device 90 back and forth to clean the work surface. When the body 91 rotates forward from the inclined position away from the floor brush assembly 94 to an upright position, the cleaning device 90 can be placed on the work surface, or... Figure 1 , Figure 2 As shown, the cleaning device 90 can be placed on the cleaning base station 10. When cleaning the work surface, the floor brush assembly 94 remains in contact with the work surface. The floor brush assembly 94 may include a floor brush housing and a floor brush rotatably connected to the floor brush housing; the floor brush can rotate relative to the work surface to wipe away stains. As shown, a suction pipe is provided within the portion of the body 91 connected to the floor brush assembly 94, and the bottom end of the suction pipe is connected to a suction port located on the floor brush assembly 94.

[0081] The wastewater tank 92 is used to hold dirt sucked from the work surface. The dirt can be wastewater generated during cleaning, or it can include various types of garbage sucked from the work surface. The bottom of the wastewater tank 92 is provided with a drain port 93 and a drain inlet. The drain port 93 of the wastewater tank 92 is used to dock with the cleaning base station 10, so as to discharge the dirt in the inner cavity of the wastewater tank 92 into the cleaning base station 10.

[0082] Specifically, such as Figures 1 to 6 As shown, the cleaning base station 10 includes a base 1, a tray 2, and a drain trough 3; the base 1 is configured to extend in the height direction and is used to install various functional components required for the cleaning base station 10, such as the drain trough 3.

[0083] The tray 2 is located at the bottom of the base 1 and extends forward horizontally relative to the base 1; the side opposite to the front side is referred to as the rear side. The tray 2 is primarily used to support the floor brush assembly 94 of the cleaning base station 10 when the cleaning equipment 90 docks with the cleaning base station 10 for waste removal. It can also be used to clean the floor brush assembly 94 of the cleaning equipment 90 or to charge the cleaning base station 10. In other words, the floor brush assembly 94 is located on the tray 2 during waste removal.

[0084] The sewage trough 3 includes a dirt-containing part 31 located within the clean base station 10 and a dirt-receiving part 32 communicating with the inner cavity of the dirt-containing part 31; the dirt-receiving part 32 is located on the front side of the dirt-containing part 31 and is configured to be connected to the side wall of the dirt-containing part 31 so as to form a receiving cavity with the dirt-containing part 31.

[0085] It is understood that the cleaning base station 10 disclosed herein 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 sewage in the recycling bin inside such a cleaning base station needs to be discharged, the sewage suction motor is turned on to suck the sewage in the recycling bin into the base station through negative pressure. In this type of cleaning base station, the sewage discharge tank only needs to be set up as a container box, which is different from the structural principle of the cleaning base station that uses gravity to discharge sewage.

[0086] During the operation of the cleaning base station 10 disclosed herein, the cleaning device 90 is placed on the tray 2, and the drain outlet 93 of the cleaning device 90 is located above the dirt-receiving part 32, and the dirt discharged by the cleaning device 90 can be discharged into the drain trough 3. The dirt-receiving part 32 is located in front of the dirt-containing part 31 and is connected to the side wall of the dirt-containing part 31. It is mainly used to receive the dirt discharged by the cleaning device 90 and guide the dirt discharged by the cleaning device 90 into the dirt-containing part 31. The dirt-containing part 31 is set in the base 1 and is mainly used to temporarily store dirt and guide the dirt discharged by the cleaning device 90 into the drain pipe 6 so that the dirt can be discharged to the outside.

[0087] Since the contaminant 32 is located on the front side of the contaminant 31 and is connected to the side wall of the contaminant 31, protruding forward from the base 1, the contaminant 32 that docks with the cleaning device 90 is located outside the cavity of the base 1 (the base 1 has a front wall surface 11 and a rear wall surface 12, the front wall surface 11 and the rear wall surface 12 are spaced apart in the second direction, the front wall surface 11, the rear wall surface 12 and the side wall connecting the front wall surface 11 and the rear wall surface 12 form the cavity of the base 1, and the contaminant 32 is located outside the front wall surface 11 of the base 1), and the contaminant 31 is located inside the cavity of the base 1 (the contaminant 31 is located inside the front wall surface 11 of the base 1), the contaminant 32 basically does not occupy the internal cavity volume of the base 1. On the one hand, it can reduce the thickness of the base 1, and on the other hand, it makes way for the volume of the contaminant 31 inside the cavity of the base 1, effectively optimizing the layout of the cleaning base station 10 of this disclosure, saving space, and facilitating the miniaturization of the cleaning base station 10. Furthermore, when the drain trough 3 becomes clogged, the dirt-receiving part 32 and the dirt-containing part 31 can jointly contain the dirt, preventing it from overflowing from the drain trough 3. Compared to existing cleaning base stations, the drain trough 3 of the cleaning base station 10 disclosed in this invention has a larger overall volume and occupies less space, effectively improving the user experience.

[0088] like Figure 6As shown, in one embodiment of this disclosure, a roller brush groove 21 is provided on the tray 2. The axial direction of the roller brush groove 21 (i.e., the length extension direction of the roller brush groove 21) is taken as the first direction, and the direction perpendicular to the first direction is taken as the second direction. Both the first and second directions are located in a horizontal plane. The dirt-holding part 31 is constructed such that its size in the first direction is larger than its size in the second direction. Since the tray of the cleaning base station needs to support 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 must 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 part 31 in the first direction is larger than its size in the second direction, this design of the dirt-holding part 31 can make full use of the space of the base station in the axial direction of the roller brush groove. Under the premise of ensuring the volume of the dirt-holding part 31 of this disclosure, the thickness of the dirt-holding part 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 goodwill, and thus facilitates the arrangement of the cleaning base station 10 of this disclosure.

[0089] like Figure 3 As shown, in one embodiment of this disclosure, the dirt-receiving part 32 is lower than the dirt-holding part 31, which facilitates cleaning of all parts of the drain trough 3 and prevents cleaning dead corners from appearing in the drain trough 3.

[0090] It is understood that in the sewage tank 3 disclosed herein, the dirt-receiving part 32 and the dirt-holding part 31 can be integrally formed and distinguished only as two parts with different functions. Alternatively, the dirt-receiving part 32 and the dirt-holding part 31 can be processed separately and then fixedly connected together. The specific processing technology is not limited here.

[0091] In order to control the operation of the clean base station 10 of this disclosure, the clean base station 10 of this disclosure may further include a control unit, which is capable of signal connecting to various components on the clean base station 10 of this disclosure in order to control their operating status.

[0092] Specifically, such as Figures 7 to 10 As shown, in one embodiment of this disclosure, the top of the soil-receiving portion 32 is configured to extend forward from the soil-containing portion 31 to form a soil-receiving opening 321; the opening direction of the soil-receiving opening 321 is configured to face upward, and it is configured to connect with the drain outlet 93 of the cleaning device 90. Since the top of the soil-receiving portion 32 extends forward from the soil-containing portion 31 to form an upward-facing soil-receiving opening 321, during the operation of the cleaning base station 10 of this disclosure, when the cleaning device 90 is placed on the tray 2, it is convenient for the drain outlet 93 of the cleaning device 90 to be located above the soil-receiving portion 32 and to connect with the soil-receiving opening 321; the dirt discharged by the cleaning device 90 can flow through the soil-receiving opening 321 into the soil-receiving portion 32, and then into the soil-containing portion 31. Figure 9 and Figure 10As shown, in one embodiment of this disclosure, the end face of the dirt-collecting port 321 is configured to extend downward at an angle from the position where it connects to the dirt-containing portion 31, so that the end face of the dirt-collecting port 321 is configured to be lower in the height direction than the position where the dirt-collecting port 321 connects to the dirt-containing portion 31. Thus, with the front side of the dirt-collecting port 321 tilted downward, when the user places the cleaning device 90 on the tray 2, it is convenient for the user to adjust the drain port 93 of the cleaning device 90 to be located obliquely above the dirt-collecting port 321, reducing interference and obstruction during docking. This facilitates docking of the drain port 93 of the cleaning device 90 with the dirt-collecting port 321, allowing the dirt discharged by the cleaning device 90 to flow through the dirt-collecting port 321 into the dirt-collecting portion 32.

[0093] In another embodiment of this disclosure, the end face of the dirt-collecting port 321 is configured to extend horizontally from the position where it connects to the dirt-containing part 31, so that the end face of the dirt-collecting port 321 is flush with the position where it connects to the dirt-containing part 31 in the height direction. Thus, with the dirt-collecting port 321 extending horizontally, after the user places the cleaning device 90 on the tray 2, the dirt-collecting part 32 can effectively support the cleaning device 90, effectively preventing the cleaning device 90 from slipping off the dirt-collecting part 32. This ensures that during the process of the cleaning device 90 discharging dirt, the drain port 93 of the cleaning device 90 is always connected to the dirt-collecting port 321, preventing the dirt discharged by the cleaning device 90 from flowing outside the cleaning base station 10 and causing pollution.

[0094] Furthermore, such as Figure 10 As shown, in one embodiment of this disclosure, the plane where the dirt-collecting port 321 is located is denoted as plane S, and the area of ​​the dirt-containing part 31 on plane S is constructed to be smaller than the area of ​​the dirt-collecting port 321 on plane S. Since the area of ​​the dirt-containing part 31 on plane S is smaller than the area of ​​the dirt-collecting port 321 on plane S, it can be ensured that the area of ​​the dirt-collecting port 321 can meet the requirements, thereby maximizing the area of ​​the drain port 93 of the cleaning equipment 90, thereby increasing the draining speed of the cleaning equipment 90; moreover, it can reduce the area of ​​the dirt-containing part 31 on plane S, thereby reducing the overall area of ​​the drain trough 3, thereby saving the space occupied by the drain trough 3 and greatly reducing the overall volume of the base 1.

[0095] Furthermore, such as Figure 10 As shown, in one embodiment of this disclosure, the soil-receiving portion 32 is configured as a tapered structure with a decreasing cross-sectional area from top to bottom. Since the soil-receiving portion 32 is mainly used to receive the dirt discharged from the cleaning equipment 90, the tapered structure with a decreasing cross-sectional area from top to bottom facilitates the diversion of the dirt discharged from the cleaning equipment 90 to the soil-containing portion 31 after receiving the dirt, and effectively saves the space occupied by the soil-receiving portion 32.

[0096] Specifically, in one embodiment of this disclosure, the soil-receiving portion 32 includes an enclosing wall 322 on the side away from the soil-containing portion 31. The enclosing wall 322 is configured to extend obliquely downward from the top of the soil-receiving portion 32 to abut against a corresponding position of the soil-containing portion 31. The distance between the top and bottom of the enclosing wall 322 and the soil-containing portion 31 gradually decreases. The soil-receiving portion 32 also includes a first sidewall 323 and a second sidewall 324 located on both sides of the enclosing wall 322. The first sidewall 323, the second sidewall 324, and the enclosing wall 322 are configured to enclose the soil-receiving portion 32 on the soil-containing portion 31. The side of the soil-receiving portion 32 opposite to the enclosing wall 322 can be open for communication with the inner cavity of the soil-containing portion 31. The soil-receiving portion 32 and the soil-containing portion 31 enclose a receiving cavity. The dirt-holding part 31 extends forward to form the dirt-receiving port 321 of the dirt-collecting part 32. The dirt-collecting part 32 and the dirt-holding part 31 are directly connected, which facilitates the modularization of the dirt-collecting part 32 and the dirt-holding part 31. The structural continuity enhances the continuity of sewage discharge and facilitates the discharge of dirt by gravity. Moreover, the dirt-collecting part 32 is mainly located outside the inner cavity of the base 1 and is used to connect with the sewage outlet of the cleaning equipment 90. The dirt-collecting part 32 basically does not occupy the inner cavity volume of the base 1. When a blockage occurs, as dirt accumulates from bottom to top, the cavity formed by the dirt-receiving part 32 and the dirt-containing part 31 jointly accommodates the dirt. That is, when the dirt rises to a lower height, the capacity of both the dirt-receiving part 32 and the dirt-containing part 31 is utilized to accommodate it. At the same time, since the dirt-receiving part 32 is formed by extending the dirt-containing part 31 on both sides, the two sides of the dirt-receiving part 32 need to connect with the two sides of the dirt-containing part 31. The shape of the dirt-containing part 31 makes the cross-sectional area at the connection point 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 accommodating cavity formed by the dirt-containing part 31 and the dirt-receiving part 32 is larger. Compared with the prior art that only uses the dirt-containing part to accommodate dirt, the volume of the drain trough is greatly reduced while ensuring the same dirt capacity. This is conducive to the miniaturization of the base station and increases user acceptance and goodwill.

[0097] Since the enclosing wall 322 is located on the side away from the dirt-holding part 31, and the top of the dirt-receiving part 32 extends downward at an angle to connect with the corresponding position of the dirt-holding part 31, the dirt-holding part 32 is mainly supported by the enclosing wall 322 to receive dirt from the cleaning equipment 90, 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-holding part 31. The first side wall 323 and the second side wall 324 are mainly used to prevent dirt from flowing outside the drain tank 3 during the process of flowing along the enclosing wall 322.

[0098] Of course, it is understandable that when the first sidewall 323 and the second sidewall 324 are constructed with their bottoms sloping towards each other, and the enclosing wall 322, the first sidewall 323, and the second sidewall 324 are collectively in the shape of a square funnel, the first sidewall 323 and the second sidewall 324 can also receive dirt from the cleaning device 90 and guide the dirt discharged by the cleaning device 90 to flow along the first sidewall 323 and the second sidewall 324 to the dirt-holding part 31. The enclosing wall 322, the first sidewall 323, and the second sidewall 324 can be integrally formed, or they can be separate parts and then fixedly connected together; the specific processing technology is not limited here.

[0099] like Figure 5 As shown, in one embodiment of this disclosure, the side of the dirt-receiving portion 32 opposite to the enclosing wall 322 is open, for communicating with the inner cavity of the dirt-containing portion 31. The projection of the dirt-receiving portion 32 toward the dirt-containing portion 31 does not exceed the maximum diameter of the dirt-containing portion 31. Since the side of the dirt-receiving portion 32 opposite to the enclosing wall 322 is open, for communicating with the inner cavity of the dirt-containing portion 31, it is convenient for dirt to flow from the dirt-receiving portion 32 into the dirt-containing portion 31. Furthermore, since the projection of the dirt-receiving portion 32 toward the dirt-containing portion 31 does not exceed the maximum diameter of the dirt-containing portion 31, the overall projection of the dirt-receiving portion 32 can fall within the area of ​​the dirt-containing portion 31, and there will be no left-right misalignment between the dirt-receiving portion 32 and the dirt-containing portion 31, which is beneficial to reducing the size of the base 1 in the axial direction of the brush groove 21.

[0100] As mentioned above, the drain trough 3 includes a dirt-containing part 31 located in the base 1 and a dirt-receiving part 32 communicating with the inner cavity of the dirt-containing part 31; the dirt-receiving part 32 is configured to have a dirt-receiving port 321 for receiving the drain outlet 93 of the cleaning equipment 90.

[0101] like Figures 7 to 10 As shown, in one embodiment of this disclosure, the soil-receiving portion 32 has a drain surface 325, and at least a portion of the dirt flowing in from the soil-receiving port 321 is configured to be guided from the drain surface 325 to the inner cavity of the soil-receiving portion 31; the area on the drain surface 325 corresponding to the drain port 93 is configured as a flat surface or a continuous smooth curved surface.

[0102] During the operation of the cleaning base station 10 disclosed herein, the cleaning device 90 is placed on the tray 2, the drain port 93 of the cleaning device 90 is located above the dirt-receiving part 32, and the dirt discharged by the cleaning device 90 can be discharged into the drain trough 3. The drain surface 325 of the dirt-receiving part 32 can receive the dirt discharged from the drain port 93 of the cleaning device 90 and guide the dirt discharged by the cleaning device 90 into the inner cavity of the dirt-containing part 31. That is, at least a portion of the dirt flowing out from the drain port 93 can flow from the drain surface 325 into the inner cavity of the dirt-containing part 31. The dirt-containing part 31 is disposed within the base 1 and is mainly used for temporarily storing dirt and guiding the dirt discharged by the cleaning device 90 into the drain pipe 6 so that the dirt can be discharged to the outside.

[0103] Specifically, since the area on the drain surface 325 corresponding to the drain outlet 93 is constructed as a flat surface or a continuous smooth curved surface, dirt will flow smoothly downwards when it falls from the drain outlet 321 onto the drain surface 325, ensuring that the dirt continues to flow towards the drain pipe 6 with greater kinetic energy. It can also prevent dirt from splashing out of the drain outlet 321 when it falls onto the drain surface 325 and onto the base 1 or tray 2 of the cleaning base station 10. This eliminates the need for users to perform secondary cleaning on the cleaning base station 10, effectively reducing the user's burden and improving the user experience.

[0104] like Figure 9 and Figure 10 As shown, in one embodiment of this disclosure, the soil-receiving portion 32 is configured to be located in front of the soil-containing portion 31, and the top of the soil-receiving portion 32 is configured to extend from the soil-containing portion 31 toward the tray 2 to form a soil-receiving opening 321. Since the soil-receiving portion 32 is located in front of the soil-containing portion 31, and the top of the soil-receiving portion 32 extends from the soil-containing portion 31 toward the tray 2 to form a soil-receiving opening 321, it is convenient for the drain outlet 93 of the cleaning device 90 to be located above the soil-receiving portion 32 and to connect with the soil-receiving opening 321; the dirt discharged by the cleaning device 90 can flow through the soil-receiving opening 321 into the soil-receiving portion 32, and then into the soil-containing portion 31. Since the soil-receiving part 32 is located on the front side of the soil-containing part 31 and is connected to the side wall of the soil-containing part 31, protruding from the base 1 to the front side, the soil-receiving part 32 is located outside the front wall surface 11 of the base 1, that is, the drain 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.

[0105] like Figure 4 As shown, in one embodiment of this disclosure, in the front-rear direction of the base 1, the end of the drain surface 325 adjacent to the tray 2 is denoted as end A, and the end away from the tray 2 is denoted as end B; the line connecting end A and end B is configured such that the angle between the line connecting end A and end B and the central axis of the drain outlet 93 is less than or equal to 40°. Since the angle between the line connecting end A of the drain surface 325 adjacent to the tray 2 and end B of the drain surface 325 and the central axis of the drain outlet 93 is less than or equal to 40°, it can be further ensured that when dirt falls from the drain outlet 93 of the cleaning device 90 onto the drain surface 325, it will not have a large impact on the drain surface 325, preventing dirt from splashing out of the receiving port 321 and onto the base 1 or tray 2 of the cleaning base station 10 when it falls onto the drain surface 325. Furthermore, it can flow smoothly downwards under gravity, ensuring that the dirt continues to flow towards the drain pipe 6 with greater kinetic energy, thereby improving the draining efficiency of the cleaning base station 10 of this disclosure. Figure 4As shown, more precisely, since the drain surface 325 is used to receive dirt falling from the drain port 90 of the cleaning equipment 90, the area of ​​the drain port 90 projected onto the drain surface 325 along the extension direction of the cleaning equipment 90 body is denoted as W. Since the drain surface 325 may be slightly curved, the angle between the tangent direction at the center point of W and the vertical direction does not exceed 40°, with the tangent direction at the center point of W as the reference.

[0106] Furthermore, such as Figure 4 As shown, in one embodiment of this disclosure, in the front-rear direction of the base 1, the end of the drain 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 end C and end D is configured to be located between end A and end B along the orthogonal projection of the central axis of the drain outlet 93. Since the orthogonal projection of the portion of the drain outlet 93 away from the front end C of the base 1 and the rear end D adjacent to the base 1 on the central axis of the drain outlet 93 is located between the aforementioned end A and end B, it can be ensured that after dirt falls from the drain outlet 93 of the cleaning device 90, it can fall into the area where the drain surface 325 is located, and will not fall directly into other positions such as the inner cavity of the dirt holding part 31, thereby avoiding the splashing of dirt directly into the inner cavity of the dirt holding part 31, and effectively exerting the guiding function of the drain surface 325.

[0107] Furthermore, in one embodiment of this disclosure, the orthographic projection of the drain outlet 93 on its central axis is located within the orthographic projection range of the drain surface 325 on the central axis of the drain outlet 93. This ensures that after the dirt falls from the drain outlet 93 of the cleaning device 90, it can fall onto the drain surface 325 and flow obliquely downward along the drain surface 325, instead of falling directly into other locations such as the inner cavity of the dirt-holding part 31, where it cannot continue to flow into the drain pipe 6 using kinetic energy.

[0108] like Figure 4 As shown, in one embodiment of this disclosure, the orthographic projection of the end D of the drain outlet 93 along the central axis of the drain outlet 93 coincides with the bottom end of the dirt-receiving part 32. In this way, it can be ensured that the drain outlet 03 can be projected on the drain surface 325, effectively utilizing the drain surface 325 to guide the flow of dirt, and there is no need to set an excessively long drain surface 325, which effectively ensures the miniaturization of the cleaning base station 10 of this disclosure.

[0109] like Figure 7As shown, in one embodiment of this disclosure, the soil-receiving portion 32 includes an enclosing wall 322 on the side away from the soil-containing portion 31, and the inner wall of the enclosing wall 322 is configured as a drain surface 325. The enclosing wall 322 is configured to extend obliquely downward from the top of the soil-receiving portion 32 to abut against a corresponding position of the soil-containing portion 31. The soil-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 soil-receiving portion 32 on the soil-containing portion 31. Since the inner wall of the enclosing wall 322 can serve as the drain surface 325, it is not necessary to separately provide a drain surface 325 within the soil-receiving portion 32, thereby effectively saving the materials required for processing the soil-receiving portion 32.

[0110] Furthermore, in one embodiment of this disclosure, the orthographic projection of the drain outlet 93 on its central axis is configured to be located between the first sidewall 323 and the second sidewall 324. That is, the orthographic projection of the drain outlet 93 on its central axis can be entirely located on the enclosing wall 322. This further ensures that after dirt falls from the drain 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, instead of falling directly into other locations such as the inner cavity of the dirt-holding part 31. This avoids dirt splashing directly into the inner cavity of the dirt-holding part 31 and prevents it from continuing to flow into the drain pipe 6 using kinetic energy.

[0111] like Figure 10 As shown, in one embodiment of this disclosure, the outlet of the sewage trough 3 is provided with an end E located on the front side and an end F located on the rear side, and the extension line of points A and B is located between ends E and F of the sewage trough 3. In this way, the dirt discharged from the sewage outlet 93 can fall directly onto the outlet of the sewage trough 3 after passing through the sewage discharge surface 325 of the dirt receiving part 32, minimizing obstruction in the sewage discharge path, and the dirt discharged later can also exert a gravitational impact on the dirt discharged earlier, which is more conducive to the discharge of dirt.

[0112] Furthermore, such as Figure 10 As shown, in one embodiment of this disclosure, the extension lines of points A and B at the outlet center point G of the sewage tank 3 are located between end E and center point G, meaning end B is located above the line connecting A and B. This allows the waste discharged from the sewage outlet 93 to fall directly onto the outlet of the sewage tank 3 after passing through the sewage discharge surface 325 of the receiving part 32, minimizing obstruction in the sewage discharge path. It is understood that the extension lines of points A and B being located between end E and center point G includes cases where the extension lines pass through either end E or center point G.

[0113] Similarly, such as Figure 10As shown, in one embodiment of this disclosure, the intersection H of the two lines DF with the dirt-receiving part 32 or the dirt-holding part 31 is located below point I, that is, there is no obstruction on the DF line. In this way, it can be further ensured that the dirt discharged from the drain outlet 93 can fall directly into the drain outlet after passing through the drain surface 325 of the dirt-receiving part 32, minimizing obstruction on the drain path.

[0114] like Figure 4 As shown, in one embodiment of this disclosure, the inclination angle of the sewage discharge surface 325 relative to the horizontal plane is configured to decrease progressively from top to bottom. It can be understood that the inclination angle of any point on the sewage discharge surface 325 relative to the horizontal plane is the angle formed between the tangent at that point and the horizontal plane, and this angle is at most a right angle. Figure 4 The angle of inclination of the drain surface 325 relative to the horizontal plane is always acute. In this way, as the dirt discharged by the cleaning device 90 falls onto the drain surface 325 and flows along the drain surface 325, it can be guided towards the bottom of the drain trough 3 under the action of the drain surface 325. This allows the dirt to flow to the bottom of the drain trough 3 as quickly as possible when it flows from the drain surface 325 to the inner cavity of the dirt holding part 31, without impacting other parts of the inner cavity of the dirt holding part 31. This effectively utilizes the kinetic energy of the dirt itself and promotes the rapid removal of dirt.

[0115] Specifically, such as Figure 4 As shown, in one embodiment of this disclosure, the area of ​​the drain outlet 93 is configured to be smaller than the area of ​​the receiving outlet 321; when the cleaning device 90 is placed in the cleaning base station 10, the orthographic projection of the drain outlet 93 on its central axis is located inside the receiving outlet 321. In this way, it can be ensured that when the cleaning device 90 is placed in the cleaning base station 10, all the dirt discharged from the drain outlet 93 of the cleaning device 90 can fall into the receiving outlet 321 and will not flow outside the receiving outlet 321, causing pollution to the cleaning base station 10. Moreover, after the dirt falls into the receiving outlet 321, even if splashing occurs, it is not easy to splash outside the receiving outlet 321, preventing dirt from splashing out of the receiving outlet 321.

[0116] like Figure 18 As shown, in one embodiment of this disclosure, a filter assembly 326 is provided in the inner cavity of the dirt-receiving part 32. The filter assembly 326 is disposed in the dirt-receiving port 321 and is configured to be detachable from the dirt-receiving port 321. The filter assembly 326 is configured to extend downward to form a filter chamber. When the cleaning device 90 is placed in the cleaning base station 10, the orthogonal projection of the drain port 93 on its central axis is located in the filter chamber.

[0117] refer to Figures 20 to 22The filter assembly 326 includes an inlet 3261, a filter section 3262, and a handle 3263. The inlet 3261 is located at the top of the filter section 3262, which is annular and forms a filter chamber. The inlet 3261 is inclined, and the plane containing the inlet 3261 forms an acute angle with the filter section 3262. The filter section 3262 has filter through holes and includes a bottom wall 3262a. The outer wall surface of the bottom wall 3262a has supporting ribs 3262b, with at least two supporting ribs 3262b for balance. The inner wall surface of the bottom wall 3262a has multiple guide ribs 3262c.

[0118] The filter assembly 326 is installed into the drain tank 3 from the sludge inlet 321. The inlet 3261 corresponds to the sludge inlet 321. After installation, the plane of the inlet 3261 is parallel (or coincides) with the plane of the sludge inlet 321. The filter part 3262, which forms an acute angle with the plane of the inlet 3261, is installed at an angle adapted to the inclination of the drain surface 325. The bottom wall 3262a is aligned with the drain surface 325, and the support rib 3262b is supported on the drain surface 325 to ensure that the filter assembly 326 is in the correct position within the drain tank 3. To avoid interference with the guide rib 327 on the drain surface 325 and to prevent the support rib 3262b from obstructing the flow of dirt, the support rib 3262b extends from top to bottom on the outer wall of the bottom wall 3262a. After the filter assembly 326 is installed in the drain tank 3, the extension direction of the support rib 3262b is consistent with the direction of dirt flow. The height of the support rib 3262b is set to be greater than or equal to the height of the guide rib 327, so that a certain gap is maintained between the bottom wall 3262a and the drain surface 325, so that the water flow can easily enter the gap between the bottom wall 3262a and the drain surface 325 when rinsing the drain tank 3, so that no dead corners are left during rinsing.

[0119] In addition, similar to the function of the guide ribs 327 on the drain surface 325, multiple guide ribs 3262c on the inner wall surface of the bottom wall 3262a extend from top to bottom. After the filter assembly 326 is installed in the drain trough 3, the extension direction of the guide ribs 3262c is consistent with the direction of dirt flow, guiding the dirt flow and helping to reduce the back splash kinetic energy after the dirt falls.

[0120] The top of the bottom wall 3262a is also provided with a notch 3262d on each side. When the cleaning equipment 90 discharges sewage, the sewage will spread to both sides after being discharged from the cleaning equipment 90. If the drainage on both sides is insufficient, the sewage will splash back. The notches 3262d on both sides play a role in quickly removing dirt and reducing the back splashing of sewage.

[0121] A handle 3263 is positioned adjacent to the inlet 3261 and is rotatably mounted across the inlet 3261. When the handle 3263 is rotated to the plane of the inlet 3261 or to a plane lower than the inlet 3261, the handle 3263 is in a retracted state. When the user needs to remove the filter assembly 326 from the drain tank 3, rotating the handle 3263 will remove the filter assembly 326 from the base station 10.

[0122] By installing a filter assembly 326 inside the contaminant receiving part 32, during the operation of the cleaning base station 10 of this disclosure, all the dirt discharged by the cleaning equipment 90 will pass through the filter assembly 326. Larger solid dirt will be filtered into the filter chamber, while the remaining dirt will fall onto the discharge surface 325 and be discharged into the discharge tank 3. Since the discharge port 93 is positioned in the cleaning base station 10, its orthogonal projection on its central axis is located inside the filter chamber, it can be ensured that all the dirt discharged by the cleaning equipment 90 can be filtered by the filter assembly 326, and there will be no situation where some dirt is not filtered by the filter assembly 326 and flows directly into the discharge tank 3.

[0123] like Figure 10 As shown, in one embodiment of this disclosure, the inclination angle of the drain surface 325 relative to the horizontal plane is configured to be smaller than the inclination angle of the side wall of the dirt-holding portion 31 located below the enclosing wall 322. Because the inclination angle of the drain surface 325 relative to the horizontal plane is smaller than the inclination angle of the side wall of the dirt-holding portion 31 located below the enclosing wall 322, the side wall of the dirt-holding portion 31 located below the enclosing wall 322 will deviate downwards from the downward path of the drain surface 325. When the wastewater discharged by the cleaning device 90 flows downwards along the drain surface 325 to the dirt-holding portion 31, most of it will not continue to flow downwards along the side wall of the dirt-holding portion 31, but will instead rush into the middle of the inner cavity of the dirt-holding portion 31. This minimizes the risk of vortexing or splashing when dirt flows to the dirt-holding portion 31, reduces the impact between dirt particles, ensures a smooth flow of dirty wastewater, and effectively increases the discharge speed of dirt from the bottom of the dirt-holding portion 31.

[0124] like Figure 17 As shown, in one embodiment of this disclosure, at least one guide rib 327 is provided on the drain surface 325. The guide rib 327 is configured to extend along the direction of dirt flow on the drain surface 325. The extension direction of the guide rib 327 can be parallel to the direction of dirt flow or at an angle to the direction of dirt flow. In this way, after the dirt discharged by the cleaning device 90 falls onto the drain surface 325, it can flow along the extension direction of the guide rib 327, reducing the splashing of dirt on the drain surface 325. The dirt will also not impact the first sidewall 323 and the second sidewall 324, thereby effectively reducing the kinetic energy loss of the dirt and ensuring that the dirt flows diagonally downward along the drain surface 325 as quickly as possible.

[0125] like Figure 3 and Figure 4 As shown, in one embodiment of this disclosure, in the cleaning system of this disclosure, the cleaning device 90 is provided with a drain outlet 93, and a lower cover 95 is provided at the drain outlet 93. The lower cover 95 has a first position with the drain outlet 93 closed and a second position with the drain outlet 93 open. The cleaning device 90 is connected to the cleaning base station 10, and the lower cover 95 can be rotated from the first position to the second position to open the drain outlet 93. When the lower cover 95 is in the second position, the lower cover 95 extends into the dirt-receiving port 321 of the dirt-receiving part 32 and is located on the side of the drain surface 325. The opening angle range of the lower cover 95 is 90°-100°.

[0126] Thus, 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 drain outlet 93. Since the lower cover 95 is in the second position, when it is in the second position, it extends into the drain outlet 321 of the dirt-receiving part 32 and is located on the side of the drain surface 325. The opening angle of the lower cover 95 is 90°-100°. Dirt inside the cleaning device 90 can flow along the lower cover 95, and the lower cover 95 will not obstruct the flow of dirt, ensuring the normal flow of dirt inside the sewage tank 92.

[0127] like Figure 18 As shown, in one embodiment of this disclosure, the soil-receiving part 32 is located on the base 1. The base 1 is provided with a mounting port 4 on one side of the tray 2 for adapting to the soil-receiving port 321. The end faces on both sides of the mounting port 4 are configured to be higher than the end faces of the soil-receiving port 321. When the user places the cleaning device 90 on the tray 2, the cleaning device 90 partially enters the mounting port 4, and the drain port 93 is located above the soil-receiving port 321. Since the end faces on both sides of the mounting port 4 are higher than the end faces of the soil-receiving port 321, it can effectively prevent dirt from splashing out from both sides of the mounting port 4 when the cleaning device 90 drains, thereby preventing dirt from polluting the outside world and improving the user experience.

[0128] Specifically, such as Figure 4As shown, the lower cover 95 of the cleaning device 90, which seals the drain outlet 93, is rotatably connected to the sewage tank 92 at end C via a rotating shaft. When the cleaning device 90 needs to discharge sewage, the lower cover 95 is unlocked from the sewage tank 92 at end D, and then rotates around the rotating shaft at end C to open the drain outlet 93. Therefore, during the sewage discharge process of the cleaning device 90, the lower cover 95 of the sewage tank 92 can effectively prevent dirt from splashing out from the front side, i.e., the side of the sewage inlet 321 away from the base 1. Moreover, the lower cover 95 of the sewage tank 92 rotates open at an angle greater than or equal to 90°, so that when dirt is discharged from the drain outlet 93, the lower cover 95 will not obstruct the sewage in the discharge path. Meanwhile, since the lower cover 95 extends into the sewage inlet 321 and abuts against the sewage discharge surface 325 after being rotated open, if the rotation angle of the lower cover 95 is too large, the space required at the sewage discharge surface 325 will also increase accordingly. The overall size of the sewage receiving part 32 extending beyond the outer side of the base 1 will also increase. Since the cleaning equipment 90 needs to be placed and removed on the cleaning base station 10, if the size of the sewage receiving part 32 protruding beyond the base 1 is too large, the floor brush assembly or the rear side of the cleaning equipment 90 will interfere with the sewage receiving part 32 when it is placed or removed, resulting in the need to redesign the cleaning base station 10. Therefore, considering both sewage discharge and the placement and removal of the cleaning equipment 90, the rotation angle of the lower cover 95 of the sewage tank 92 should not exceed 100°, and it should abut against the sewage discharge surface 325 when open, so as to ensure convenient docking and removal of the cleaning equipment without affecting sewage discharge.

[0129] Furthermore, in its upright position, the cleaning equipment 90 typically forms an acute angle with the floor brush assembly, resulting in a forward-leaning posture. This upright body generally supports heavy components such as the fan unit and battery. To support the cleaning equipment 90 and prevent it from tipping forward on the base station, [further details are needed]. Figure 18 As shown, in one embodiment of this disclosure, the end faces on both sides of the mounting port 4 are configured to extend forward to form ribs 41. The ribs 41 are configured to engage with the bottom of the cleaning device 90 body 91 or the wastewater tank 92. Specifically, a groove can be provided at the bottom of the body 91 or the bottom of the wastewater tank 92. At least two symmetrical grooves are provided at the bottom of the body 91 or the bottom of the wastewater tank 92. When the user places the cleaning device 90 on the cleaning base station 10, the floor brush assembly 94 is supported on the tray 2. The ribs 41 on the front side of the mounting port 4 can engage with the grooves at the bottom of the cleaning device 90 body 91 or the bottom of the wastewater tank 92, thereby effectively preventing the cleaning device 90 from slipping off the mounting port 4 or relatively deflecting, ensuring the normal operation of the sewage discharge process. 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 drain port 93 of the body 91 or the sewage tank 92, making it convenient for the user to place the cleaning equipment 90 in the mounting port 4.

[0130] like Figure 9 As shown, in one embodiment of this disclosure, the soil-holding portion 31 is configured to have at least a variable-diameter portion whose dimensions increase from top to bottom, and the soil-receiving portion 32 is configured to be at least connected to the variable-diameter portion and is configured to transitionally connect with the sidewall of the variable-diameter portion. The dirt flowing from the dirt-receiving section 32 mainly flows to the lower middle part of the dirt-holding section 31 and is then discharged through the drain pipe 6. The lower middle part of the dirt-holding section 31 is an effective part for temporarily storing dirt. Designing the dirt-holding section 31 to have at least a variable diameter section with an increasing size from top to bottom can effectively expand the volume of the inner cavity in the dirt-holding section 31 that plays the main role in temporarily storing dirt, thereby temporarily storing the dirt discharged by the cleaning equipment 90. Even if a blockage occurs, the dirt will mainly accumulate in the lower middle part of the dirt-holding section 31, avoiding the distance between the dirty water surface and the dirt-receiving port 321 being too close. At the same time, it can also effectively reduce the volume of the upper part of the dirt-holding section 31, which has a smaller role in storing dirt. Thus, the structure of the dirt-holding section 31 is reasonably designed so that the dirt-holding section 31 can maximize the reduction of the space occupied by the dirt-holding section 31 while ensuring sufficient capacity. Furthermore, as mentioned above, the dirt-receiving section 32 has a tapering structure with a decreasing volume from top to bottom, which can ensure that the overall width of the drain tank 3 of this disclosure will not increase significantly. Furthermore, since the soil-collecting part 32 is at least connected to the variable diameter part and transitionally connected to the side wall of the variable diameter part, that is, the connection position between the soil-collecting part 32 and the variable diameter part is located on the extension path of the variable diameter part itself, the soil-collecting part 32 does not extend into the inner cavity of the soil-containing part 31, and the soil-collecting part 32 will not form an obstruction in the inner cavity of the soil-containing part 31, thus not hindering the sewage from falling; moreover, there will be no cleaning dead corner at the connection position between the soil-collecting part 32 and the soil-containing part 31, thereby facilitating the cleaning of the sewage tank 3 and ensuring that the sewage tank 3 can be cleaned thoroughly.

[0131] Specifically, such as Figure 9As shown, in one embodiment of this disclosure, the soil-holding portion 31 includes a first portion 311 located above and a second portion 312 located below. 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 a cross-sectional area increasing from top to bottom. The soil-holding portion 32 is configured to be transitionally connected to the first portion 311, and the size of the second portion 312 is configured to have a gradually shrinking structure with a cross-sectional area decreasing from top to bottom. The first part 311 of the dirt-holding section 31 has a gradually expanding cross-sectional area from top to bottom, which facilitates the formation of a variable-diameter section with increasing dimensions from top to bottom. This allows for temporary storage of dirt during the discharge of dirt by the cleaning equipment 90. The gradually increasing cross-sectional area of ​​the dirt-holding section 31, coupled with the dirt-receiving section 32 connecting to both sides of the first part 311, further expands the lower storage area, thus increasing the blockage capacity. The second part 312, with a gradually decreasing cross-sectional area from top to bottom, connects to the drain pipe 6, facilitating the diversion of dirt discharged by the cleaning equipment 90 into the drain pipe 6. This ensures that all dirt is discharged into the drain pipe 6 after the cleaning equipment 90 has finished discharging, preventing dirt residue in the dirt-holding section 31. Furthermore, the gradually increasing cross-sectional area of ​​the first part 311 and the gradually decreasing cross-sectional area of ​​the second part 312 facilitate the flow of rinsing water from the top of the drain tank down the inner wall of the drain tank, effectively rinsing it. Furthermore, the first part 311 has a continuously smooth, expanding structure with a cross-sectional area gradually increasing from top to bottom, while the second part 312 has a continuously smooth, contracting structure with a cross-sectional area gradually decreasing from top to bottom. Firstly, the continuously smooth structure facilitates the flow of flushing water. Secondly, under the condition of facilitating flushing, the continuously smooth structure further ensures that the distance between the first sidewall 323 and the second sidewall 324 of the dirt-receiving part 32, which connects to both sides of the first part 311, is maximized. This means that the area enclosed by the dirt-receiving part 32 is maximized, and the volume enclosed by the dirt-receiving part 32 and the dirt-containing part 31 is maximized, increasing the blockage capacity and helping to reduce the volume occupied by the drain tank. Specifically, as shown... Figure 9 As shown, in one embodiment of this disclosure, the soil-receiving portion 32 is formed on the first portion 311 of the soil-containing portion 31, and includes a surrounding wall 322 on the side away from the soil-containing portion 31. The surrounding wall 322 is configured to extend obliquely downward from the top of the soil-receiving portion 32 to transitionally connect with the bottom of the first portion 311. In this way, as the wastewater discharged by the cleaning device 90 flows downward along the surrounding wall 322, it 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 meet, which is the part with the largest inner diameter of the soil-containing portion 31. This can effectively reduce the impact and splashing of dirt on the inner wall of the soil-containing portion 31, avoid the formation of vortices in the soil-containing portion 31, reduce the residence time of dirt in the soil-containing portion 31, and improve the sewage discharge efficiency of the sewage discharge tank 3 of this disclosure.

[0132] Furthermore, in one embodiment of this 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. That is, as... Figure 10 As shown, the side wall of the second part 312 will deviate downward from the path of the enclosing wall 322 extending downward. When the sewage discharged by the cleaning device 90 flows downward along the enclosing wall 322 to the second part 312, most of it will not continue to flow downward along the side wall of the second part 312, but will rush into the middle of the inner cavity of the dirt holding part 31. This will minimize the generation of vortices or splashes when the dirt flows to the second part 312, reduce the impact between dirt, ensure the smooth flow of dirty sewage, and thus effectively improve the discharge speed of dirt from the bottom of the dirt holding part 31.

[0133] It is understandable that the angle of inclination of the enclosing wall 322 relative to the horizontal plane is less than the angle of inclination of the part of the second part 312 located below the enclosing wall 322. This means that the angle of inclination of any point of the enclosing wall 322 relative to the horizontal plane is less than the angle of inclination of any point of the part of the second part 312 located below the enclosing wall 322.

[0134] like Figure 9 As shown, in one embodiment of this disclosure, the waste collection port 321 is configured to extend beyond the second portion 312 in the direction of the tray 2 from the location connected to the first portion 311. Since the waste collection port 321 extends beyond the second portion 312 in the direction of the tray 2 from the location connected to the first portion 311, it facilitates docking of the waste collection port 321 with the cleaning device 90, thereby increasing the area of ​​the waste collection port 321 within a limited space, and facilitating docking of the waste discharge port 93 of the cleaning device 90 with the waste collection port 321.

[0135] like Figure 9 As shown, in one embodiment of this 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.

[0136] Understandably, since the first part 311 of the dirt-holding section 31 has a dirt-receiving section 32, which is used to guide the wastewater in the wastewater tank of the cleaning equipment to the drain outlet, and the first part 311 temporarily stores dirt during the process of the cleaning equipment 90 discharging dirt, the main function of the second part 312 is to guide the dirt discharged by the cleaning equipment 90 into the drain pipe 6, and at the same time, it temporarily stores dirt together with the dirt-receiving section 32 when the drain tank is blocked; when the dimension of the first part 311 in the height direction is larger than the dimension of the second part 312 in the height direction, it is beneficial for the dirt-receiving section 32 to guide the dirt as close to the bottom as possible. The location also effectively ensures that the volume of the first part 311 meets the requirements, preventing dirt from overflowing from the drain trough 3 when the cleaning equipment 90 discharges wastewater too quickly or when the drain pipe 6 becomes blocked. The second part 312 also forms a relatively low and wide area, facilitating the rapid discharge of dirt from the dirt-holding part 31 and reducing the overall height of the dirt-holding part 31. Furthermore, when rinsing the drain trough, the greater height of the first part 311 results in a steeper slope of its arc surface, which facilitates the downward flow of cleaning water from the top of the first part 311 along its inner arc surface. In addition, since the base station also has some horizontal drain pipes inside besides the drain trough, and these drain pipes have a capacity, the height of the second part can be appropriately reduced, lowering the overall height without affecting the capacity below the detection position 81 described below.

[0137] As attached Figure 10 As shown, OJ is the vertical line passing through point B, OEF is the horizontal line passing through points E and F on the upper surface of the bottom outlet of the sewage tank 3, AJ is the horizontal line passing through point A, ABK is the straight line passing through points A and B, point K is the intersection of the extension of AB and line OEF, h1 is the vertical height from point A to point B, and h2 is the height from point B to point E, which is also the vertical height of the second part 312.

[0138] When designing the drain trough, since the drain outlet of the drain section needs to be connected to the body of the cleaning equipment, point A is the point on the drain outlet 321 that is farthest from the front wall 11 of the base 1, which is fixed. The plane where the bottom outlet of the drain trough 3 is located is also basically fixed, approximately the plane where the upper surface of the tray is located (because the space below the upper surface of the base of the tray needs to accommodate the drain pipe 6) or the plane where the charging contacts are located (to set the shrinkage part 34). Therefore, the vertical height |OJ| from point A to point E is also fixed, which is the vertical height from point A to the bottom outlet of the drain trough 3, denoted as S2, and h1+h2=|OJ|=S2. Point B is the intersection point where the soil-receiving part extending from point A into the base at a certain angle (the acute angle formed by line AB and the vertical line OJ; for ease of calculation and explanation, this angle is approximated as the discharge angle θ) and intersects the vertical outer surface of the base. In other words, the vertical line OJ is fixed, essentially the front vertical surface of the base, and point B is essentially a point on or near the front vertical surface of the base. Depending on the discharge angle, point B can move up and down along the vertical line OJ. Therefore, the length of AJ, |AJ|, is also essentially fixed, representing the horizontal distance from point A to or near the front wall surface 11 of the base, denoted as S1, where |AJ| = S1. Figure 10 tanθ = |AJ| / h1 = |OK| / h2, that is, h1 / h2 = |AJ| / |OK|. As mentioned before, to ensure the sewage discharge angle θ is within 40°, h1 ≥ |AJ| / tanθ, which is the minimum value of h1, and also the minimum value of h1 / h2. Furthermore, the extension of AB ideally falls between points E and F. When |OK| = |OE|, h1 is at its maximum value, and h1 / h2 is also at its maximum value. In this case, 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 of AB passes through point F, the requirement of a sewage discharge angle within 40° is not met. Therefore, the minimum value of h1 is determined by satisfying the sewage discharge angle. That is, (|AJ| / tanθ) / (|OJ|-|AJ| / tanθ)≤h1 / h2≤|AJ| / |OE|, where |OE| is the horizontal distance from point (O) near the front wall 11 of the base 1 to the front wall 11 or its vicinity of the outlet of the sewage trough 3, denoted as S3. Also, (S1 / tanθ) / (S2-S1 / tanθ)≤h1 / h2≤S1 / S3.

[0139] In addition, to prevent dirt from accumulating in the sewage tank 3 during the sewage discharge of the cleaning equipment 90 and not being able to be discharged in time, the outlet length |EF| of the sewage tank 3 is set to be no less than the length |AJ|. At the same time, in order to minimize the size of the base station, the outlet length |EF| of the sewage tank 3 does not need to be too large. Optimally, |EF|≈|AJ|.

[0140] In this example, based on the general dimensions of cleaning equipment 90 in the art, |OJ|≈2.3|AJ|.

[0141] In this example, since the sewage discharge angle needs to be kept within 40° to prevent dirt from splashing out when it falls, point B is at the highest position allowed when the sewage discharge angle is exactly 40°. At this time, h1 has the first condition: |AJ| / h1min=tan40°, h1min=1.2|AJ|, then h2max=1.1|AJ|, that is, h1 / h2≥1.1.

[0142] As mentioned above, the extension of AB should ideally fall between points E and F, allowing the contaminant to be guided by segment AB and fall directly into the bottom outlet EF of the drainage trough 3. Under this condition, point B can be located between the intersection of line AE and line OJ and the intersection of line AF and line OJ. Theoretically, the outlet E of the drainage trough 3 can be infinitely close to the front surface of the base, but |EF| is fixed. The outlet of the drainage trough 3 needs to be connected to the pipe opening of the drainage pipe 6. The outlet of the drainage trough 3 is generally located in the center of the base, and the base station needs to accommodate various other components. In this embodiment, the distance between point E and the vertical line of OJ (front surface of the base) is |OE|≈0.5|AJ|. When the extension of AB passes through point E, h1 / h2=2, and the drainage angle is 33°; when the extension 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 for h1 / h2 is 1.1-2.

[0143] Furthermore, considering the smoothness of sewage discharge, the flushing of the sewage trough, and maximizing the volume of the sewage trough, point B is simultaneously designated as the point with the largest lateral diameter of the sewage-holding part, which is also the boundary between the first part 311 and the second part 312. The maximum lateral diameter of the sewage-holding part is directly related to the thickness of the base station; the greater the thickness of the base station, the larger the maximum lateral diameter of the sewage-holding part can be. It can be envisioned that, to ensure smooth sewage discharge and flushing of the sewage trough, there should only be a smooth arc surface from point B to the outlet point E of the sewage trough. Based on this, if the maximum lateral diameter of the sewage-holding part is above point B, imagine... Figure 10If the overall contaminant holding section is moved upwards, the dirt falling through section AB will most likely fall into section BE before being discharged, rather than falling directly into the outlet EF. However, if the maximum lateral diameter of the contaminant holding section is below point B, the cross-sectional area of ​​the cavity formed by the contaminant receiving section and the first part 311 near point B will decrease, resulting in a smaller cavity volume. Furthermore, to ensure that section BE has only one smooth arc surface, the arc surface of the original contaminant holding section needs to be shrunk inwards to the BE arc surface, further reducing the overall volume. Therefore, considering all factors, using point B as the point of maximum lateral diameter of the contaminant holding section is the optimal embodiment. That is, the intersection of the contaminant receiving section and the contaminant holding section is the point of maximum lateral diameter of the contaminant holding section, and it is the boundary point between the first part 311 and the second part 312. In the above analysis, to prevent dirt from splashing back out when it falls onto 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, meaning 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 part 311 is larger than the vertical dimension of the second part 312.

[0144] like Figures 6 to 10 As shown, in one embodiment of this disclosure, the second part 312 has a larger dimension in the first direction than in the second direction. That is, the thickness of the dirt-holding part 31 in the front-back direction is less than its width in the left-right direction. Since the base station tray needs to support the floor brush of the cleaning equipment, the base station has a dimension in the axial direction of the roller brush groove 21 that is at least greater than or equal to the axial length of the roller brush groove 21. This design of the dirt-holding part 31 can make full use of the space of the base station in the axial direction of the roller brush groove 21. While ensuring the volume of the dirt-holding part 31 of this disclosure, the thickness of the dirt-holding part 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 goodwill, and thus facilitates the arrangement of the cleaning base station 10 of this disclosure.

[0145] The sewage outlets of existing clean base stations are mostly located at the back of the base station. The sewage outlet is then connected to a horizontal extension pipe to the drain. In this way, the dirt discharged from the sewage tank flows through a bend to the sewage outlet of the base station, and then through another bend at the sewage outlet of the base station before flowing away into the external extension pipe. The dirt goes through two 90° bends, which greatly consumes the kinetic energy of the dirt and makes the sewage discharge not smooth.

[0146] like Figure 5 As shown, in one embodiment of this disclosure, the sewage pipe 6 is configured to communicate with the bottom of the sewage tank 3; the sewage pipe 6 has at least a sewage section 62 extending laterally, and a connecting section 61 connecting the sewage section 62 and the bottom of the sewage tank 3, one end of the connecting section 61 is configured to extend toward the bottom of the sewage tank 3 to communicate with the bottom of the sewage tank 3, and the other end is configured to extend toward the sewage section 62 to communicate with the sewage section 62, and the sewage section 62 extends in a first direction.

[0147] During the operation of the cleaning base station 10 of this disclosure, the floor brush assembly 94 of the cleaning device 90 is placed on the tray 2, and the drain port 93 of the cleaning device 90 discharges dirt into the drain trough 3 inside the base 1. The dirt flows from the bottom of the drain trough 3 into the connecting section 61 of the drain pipe 6, and then flows along the drain section 62. Since the drain section 62 extends along the first direction, the overall width of the cleaning base station 10 can be effectively utilized to arrange the drain section 62, thereby reducing the overall length of the cleaning base station of this disclosure in the second direction.

[0148] Furthermore, since the sewage discharge section 62 extends along the first direction, the sewage only needs to go through one turn in the connecting section 61 during the process of flowing to the sewage discharge section 62. The sewage discharge section 62 extends in the same direction as the external extension pipe connected to the sewage discharge outlet of the base station, which can effectively reduce the kinetic energy loss of the sewage during the sewage discharge process and make the sewage discharge smoother.

[0149] It is understandable that the horizontally extending sewage section 62 can extend horizontally, or it can not be completely parallel to the horizontal plane, or it can gradually extend downwards. That is, both downward extension and horizontal extension can be considered horizontal extension.

[0150] like Figure 1 , Figure 5 , Figure 6 As shown, in one embodiment of this disclosure, the sewage discharge section 62 has a sewage discharge outlet 620 located on the side of the base 1. The side of the base 1 is the surface of the base 1 in the first direction. Thus, the sewage discharge outlet 620 of the sewage discharge section 62 can be formed on the side of the base 1, i.e., the surface of the base 1 in the first direction. The sewage discharge outlet 620 is used to connect to the sewer pipe 64. This facilitates the connection of the cleaning base station 10 of this disclosure to the sewer pipe 64 from the side, making the overall pipeline installation convenient and reducing the volume occupied by the cleaning base station 10 of this disclosure. Furthermore, since 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 align the extension direction of the sewage discharge section 62 with that of the external extension pipe connected to the sewage discharge outlet 620 of the base station, effectively reducing the kinetic energy loss of dirt during sewage discharge and making sewage discharge smoother.

[0151] like Figure 3 As shown, in one embodiment of this disclosure, the cleaning base station 10 further includes a shrinkage portion 34, the second portion 312 is connected to the shrinkage portion 34, the shrinkage portion 34 is connected to the sewage pipe 6, the sewage pipe 6 forms a sewage outlet connected to the sewer on the side of the cleaning base station 10, the shrinkage portion 34 has a gradually shrinking structure with a cross-sectional area decreasing from top to bottom, and the slope of the inner wall surface of the shrinkage portion 34 is greater than the slope of the inner wall surface of the second portion 312.

[0152] The sewage pipe 6 is connected to the bottom outlet of the sewage trough 3 via the contraction section 34. The area of ​​the bottom outlet of the sewage trough 3 is larger than the area of ​​the pipe opening of the sewage pipe 6. The contraction section 34 is vertically installed inside the base station, and its cross-sectional area gradually decreases from top to bottom, so as to connect the bottom outlet of the sewage trough 3 with the sewage pipe 6, which has a smaller pipe opening. The slope of the arc surface of the contraction section 34 is greater than the slope of the arc surface of the second part 312, so that the dirt falling from the bottom outlet of the sewage trough 3 can fall directly onto the pipe opening of the sewage pipe 6, minimizing the probability of dirt falling onto the wall of the contraction section 34 and reducing potential energy loss. The contraction section 34 causes the pipe opening from point B to the sewage pipe 6 to pass through two different arc surfaces, gradually contracting instead of directly and smoothly contracting from point B to the sewage pipe 6 opening. This increases the volume of the lower part, which helps to reduce the thickness of the base station. Furthermore, the slope of the two arc surfaces gradually increases, which helps the dirt to fall directly to the sewage pipe 6 opening, increasing the smoothness of sewage discharge and avoiding potential energy loss caused by dirt colliding with the arc surface.

[0153] like Figure 5 As shown, the clean base station of this disclosure also includes a sewage discharge assist device 70, the output port 701 of which is configured to be located at a position corresponding to the connecting section 61, and is configured to provide a pressure source to at least the area of ​​the connecting section 61 through the output port 701.

[0154] To prevent solid waste from accumulating in the drainage section 62 and causing blockage in the drainage pipe 6, the drainage assist device 70 provides a pressure source to at least the area of ​​the connecting section 61 through the output port 701. This increases the flow rate of the dirt in the drainage section 62 of the drainage pipe 6, preventing solid waste from accumulating in the drainage section 62 and causing blockage in the drainage pipe 6. This not only ensures that the cleaning base station 10 of this disclosure can normally discharge the dirt from the cleaning equipment 90 to the sewer or other external environment, but also prevents the drainage pipe 6 from becoming blocked, avoiding the need for users to manually clean the blocked drainage pipe 6. This effectively reduces the user's burden and improves the user experience.

[0155] In one embodiment of this disclosure, the sewage discharge assist device 70 is configured to provide a positive pressure source to the area of ​​the connecting section 61. That is, when the sewage discharge assist device 70 provides a positive pressure source to the area of ​​the connecting section 61, it can accelerate the flow of dirt within the connecting section 61 of the sewage pipe 6, thereby accelerating its flow along the sewage discharge section 62 of the sewage pipe 6 to be discharged to the outside as quickly as possible. It is understood that when the sewage discharge assist device 70 provides a positive pressure source to the area of ​​the connecting section 61, it can be disposed within the connecting section 61, or it can be located on the rear side of the connecting section 61 in the direction of dirt flow, such as within the sewage trough 3.

[0156] In another embodiment of this disclosure, the sewage discharge assist device 70 is configured to provide a negative pressure source to the area of ​​the connecting section 61. This negative pressure creates suction, accelerating the flow of dirt within the connecting section 61 of the sewage pipe 6. It can also accelerate the flow of dirt along the sewage discharge section 62 of the sewage pipe 6 until it is discharged to the outside. It is understood that when the sewage discharge assist device 70 provides a negative pressure source to the area of ​​the connecting section 61, it can be located within the connecting section 61 or at the front side of the connecting section 61 in the direction of dirt flow, such as within the sewage discharge section 62 or at the outlet of the sewage discharge section 62.

[0157] Specifically, such as Figure 5 As shown, in one embodiment of this disclosure, the output port 701 of the sewage assist device 70 is configured to be located on the side of the connecting section 61 opposite to the sewage discharge section 62, and the pressure source provided by the sewage assist device 70 is configured to output through the output port 701 and the connecting section 61 towards the sewage discharge section 62. Thus, during the operation of the sewage assist device 70, the pressure provided by the sewage assist device 70 can be output through the output port 701 from the connecting section 61 towards the sewage discharge section 62, thereby promoting the movement of dirt from the connecting section 61 towards the sewage discharge section 62, and thus accelerating the flow of dirt within the sewage pipe 6.

[0158] like Figure 5 As shown, in one embodiment of this disclosure, the central axis of the output port 701 is configured to be parallel to the central axis of the drain section 62. Because the central axis of the output port 701 is parallel to the central axis of the drain section 62, the drain assist device 70 can output pressure along the extension direction of the drain section 62. While accelerating the flow of dirt within the drain pipe 6, this minimizes the rotation of dirt within the drain section 62, thereby allowing the dirt to be discharged from the drain section 62 as quickly as possible.

[0159] Furthermore, in one embodiment of this disclosure, the connecting segment 61 is configured to be arc-shaped; the orthographic projection of the output port 701 of the sewage discharge assist 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 segment 62 in the first direction.

[0160] Because the connecting section 61 is constructed in an arc shape, dirt flowing downwards into the connecting section 61 under gravity can then flow along the inner cavity of the connecting section 61 into the drain section 62. Since the orthographic projection of the output port 701 of the drain assist device 70 in the extending direction of the drain section 62 is configured to at least partially overlap with the orthographic projection of the inner cavity of the drain section 62 in its extending direction, it can be ensured that the pressure source output by the drain assist device 70 can directly act on the dirt in the inner cavity of the drain section 62, thereby effectively improving the utilization efficiency of the pressure source output by the drain assist device 70 and accelerating the flow of dirt as much as possible.

[0161] Specifically, such as Figure 5 As shown, in one embodiment of this disclosure, the sewage discharge assist device 70 is a jet assembly 7. The jet assembly 7 includes a jet element 72 with a jet outlet 71. The jet element 72 is configured to discharge 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 flowing out of the jet outlet 71 flows along the first direction. That is, during the operation of the jet assembly 7, the jet element 72 of the jet assembly 7 can discharge pressurized fluid from the jet outlet 71 in the first direction. The pressurized fluid can flow along the first direction, pushing the dirt to flow faster in the connection section 61 of the sewage pipe 6, thereby accelerating the flow along the sewage discharge section 62 of the sewage pipe 6 to be discharged to the outside as quickly as possible.

[0162] Understandably, if a jetting element is added to an existing clean base station to assist in wastewater discharge, the distance from the jetting element to the wastewater outlet is very short because it faces the outlet directly behind the base station, and the water flow from the jetting element is blocked by the bend in the outlet, making it difficult to effectively assist in wastewater discharge. However, in the clean base station disclosed herein, because the jetting element 72 of the jetting assembly 7 can discharge pressurized fluid from the jetting outlet 71 in the first direction, the pressurized fluid is not blocked after being ejected, extending the assisting path of the pressurized fluid and maximizing its role in assisting in wastewater discharge.

[0163] It is understandable that, such as Figure 5 As shown, the pressurized fluid can be a pressurized liquid. After flowing in from the jet inlet, the pressurized liquid can merge into the dirt in the connecting section 61 and, under its own kinetic energy, push the dirt along the discharge section 62 towards the outlet of the discharge section 62. In another embodiment of this disclosure, the pressure source can also be pressurized gas. The pressurized gas can also push the dirt along the discharge section 62 towards the outlet of the discharge section 62 under its own pressure. The principle is similar and will not be described again here.

[0164] Specifically, such as Figure 5 As shown, in one embodiment of this disclosure, a pipe joint 630 is provided on the side of the connecting section 61 opposite to the sewage discharge section 62; the jetting element 72 is configured to be installed inside 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, the pipe joint 630 needs to be processed on the side of the connecting section 61 opposite to the sewage discharge section 62; when installing the jetting element 72, the jetting element 72 is installed inside the pipe joint 630, and the jet outlet 71 is made to face the direction of the connecting section 61 and the sewage discharge section 62. This ensures that after the pressurized fluid flows out from the jet outlet 71, it can flow along the pipe joint 630 towards the side where the sewage discharge section 62 is located, thereby pushing the dirt along the sewage discharge section 62 towards the outlet direction of the sewage discharge section 62.

[0165] Furthermore, such as Figure 5As shown, in one embodiment of this disclosure, the pipe connector 630 is a sleeve 63, and the jetting element 72 is configured to be installed inside the sleeve 63; the bottom of the sleeve 63 is configured to be higher than the bottom of the drain section 62, and the top of the sleeve 63 is configured to be lower than the top of the drain section 62.

[0166] Since the bottom of the sleeve 63 is higher than the bottom of the drain section 62 and the top of the sleeve 63 is lower than the top of the drain section 62, after the jet component 72 is installed inside the sleeve 63, it can be ensured that the bottom of the jet outlet 71 is higher than the bottom of the drain section 62 and the top of the jet outlet 71 is lower than the top of the drain section 62. After the pressurized fluid flows out from the sleeve 63, it can directly impact the dirt in the drain pipe 6 and push the dirt along the rear section of the connecting section 61 to the drain section 62. The pressurized fluid will not impact the inner wall of the connecting section 61 or other positions, thereby effectively avoiding the waste of the kinetic energy of the pressurized fluid, thereby improving the effect of the jet component 7 in pushing the dirt to flow and preventing the dirt from clogging the drain pipe 6.

[0167] Furthermore, such as Figure 5 As shown, in one embodiment of this disclosure, the sleeve 63 is configured to extend from the inner wall of the connecting section 61 in a direction away from the drain section 62, and the opening of the sleeve 63 on the inner wall of the connecting section 61 is configured to fit the shape of the inner wall of the connecting section 61. Because the sleeve 63 extends from the inner wall of the connecting section 61 in a direction away from the drain section 62, and the opening of the sleeve 63 on the inner wall of the connecting section 61 fits 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. Dirt does not flow along the connecting section 61 and is not obstructed by the sleeve 63, thus ensuring that dirt can flow smoothly along the connecting section 61. Furthermore, during the flow through the opening of the sleeve 63, it is accelerated towards the drain section 62 by the pressure of the pressurized fluid.

[0168] like Figure 5 As shown, in one embodiment of this disclosure, a fluid conduit communicating with the jetting element 72 is provided on the base 1. The fluid is configured to flow into the jetting element 72 through the fluid conduit under the action of a power source device. Thus, during the jetting assembly 7 process, the fluid can be pressurized under the action of the power source device and flow into the jetting element 72 through the fluid conduit, and then flow out from the jetting outlet 71 of the jetting element 72. It is understood that the fluid can be tap water or cleaning fluid, etc., and can come from external water sources such as tap water faucets, or from water tanks or cleaning fluid tanks inside the base station. The power source device can be a water pump or related device, and is not limited thereto.

[0169] In another embodiment of this disclosure, a fluid conduit communicating with the jetting element 72 is provided on the base 1. The fluid conduit is configured to connect to a tap, and the fluid in the tap is configured to flow into the jetting element 72 through the fluid conduit under its own water pressure. It is understood that, since the tap has its own water pressure, when the fluid conduit is connected to the tap, the fluid in the tap can flow into the jetting element 72 through the fluid conduit under its own water pressure, and then flow out from the jetting outlet 71 of the jetting element 72.

[0170] like Figure 5 As shown, in one embodiment of this disclosure, the jetting element 72 includes a jetting tube 721 and a jetting outlet 71 disposed on the end face of the jetting tube 721; the jetting element 72 also includes a venturi tube 722 located within the jetting tube 721, and the fluid is configured to be discharged from the jetting outlet 71 after passing through the venturi tube 722.

[0171] During the operation of the jet assembly 7, when the pressurized fluid flows into the jet tube 721 of the jet component 72, it passes through the venturi tube 722 inside the jet tube 721 and then exits from the jet outlet 71. The pressurized fluid, after passing through the venturi tube 722, achieves a high flow velocity and good stability. Specifically, when the total flow area of ​​the jet outlet 71 is less than the minimum flow cross-sectional area of ​​the venturi tube 722, the discharge jet can achieve a higher flow velocity, thereby improving the efficiency of the pressurized fluid in accelerating the removal of contaminants.

[0172] like Figure 5 As shown, in one embodiment of this disclosure, the jet member 72 is configured to be located on the side of the connecting section 61 opposite to the drain section 62, and the opening direction of the jet outlet 71 is configured to extend toward the drain section 62; the jet outlet 71 at least partially overlaps with the inner cavity of the drain section 62 in the height direction.

[0173] Since the jet component 72 is located on the side of the connecting section 61 opposite to the drain section 62, and the opening direction of the jet outlet 71 faces the extension direction of the drain section 62; the jet outlet 71 overlaps at least partially with the inner cavity of the drain section 62 in the height direction, it can ensure that the pressurized fluid output by the jet component 7 flows out from the jet outlet 71 and can flow along the extension direction of the drain section 62 towards the drain section 62, thereby impacting the dirt in the connecting section 61 and directly pushing the dirt along the rear section of the connecting section 61 towards the drain 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.

[0174] like Figure 5As shown, in one embodiment of this disclosure, the central axis of the jet outlet 71 is configured to be parallel to the central axis of the drain section 62. Because the central axis of the jet outlet 71 is parallel to the central axis of the drain section 62, the pressurized fluid flowing from the jet outlet 71 can flow along the central axis of the drain section 62. During the process of the pressurized fluid pushing the dirt through the drain pipe 6, the dirt is prevented from rotating within the drain section 62 as much as possible, thereby allowing the dirt to be discharged from the drain section 62 as quickly as possible.

[0175] It is understood that the central axis of the jet outlet 71 refers to the axis obtained by extending the jet outlet 71 along the direction of its extension through the center point between the highest and lowest points of the jet outlet 71. The jet outlet 71 can be set symmetrically above and below as a whole, or it can be set asymmetrically, without any restrictions here.

[0176] Furthermore, such as Figure 5 As shown, in one embodiment of this 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, due to gravity, the pressurized fluid will fall a certain distance as it flows from the jet outlet 71 into the sewage discharge pipe 6, meaning that the center position of the pressurized fluid entering the sewage discharge pipe 6 is lower than the center position of the jet outlet 71.

[0177] Therefore, when the central axis of the jet outlet 71 is higher than the central axis of the sewage discharge section 62, the center position of the pressurized fluid entering the sewage discharge pipe 6 can be located near the central axis of the sewage discharge section 62. This ensures that the pressurized fluid can impact the dirt in the sewage discharge section 62 from the center position, preventing the dirt from rotating along the axial direction of the sewage discharge pipe 6 under the action of the pressurized fluid and remaining in the sewage discharge pipe 6 and unable to be discharged quickly. This speeds up the flow of dirt along the sewage discharge pipe 6 and facilitates the discharge of dirt from the sewage discharge pipe.

[0178] like Figure 5 As shown, in one embodiment of this disclosure, the top of the jet outlet 71 is configured to be lower than the top of the inner cavity of the drain section 62. Because the top of the jet outlet 71 is lower than the top of the inner cavity of the drain section 62, after the pressurized fluid flows out from the jet outlet 71, the fluid located above the jet outlet 71 can directly impact the dirt inside the drain pipe 6 and push the dirt along the rear section of the connecting section 61 towards the inner cavity of the drain section 62, without impacting the dirt to a position on the connecting section 61 higher than the top of the inner cavity of the drain section 62. This effectively avoids wasting the kinetic energy of the pressurized fluid, thereby improving the effect of the jet assembly 7 in driving the dirt flow and preventing dirt from clogging the drain pipe 6.

[0179] Similarly, such as Figure 5As shown, in one embodiment of this disclosure, the bottom end of the jet outlet 71 is configured to be higher than the bottom end of the inner cavity of the drain section 62. Since the bottom end of the jet outlet 71 is higher than the bottom end of the inner cavity of the drain section 62, after the pressurized fluid flows out from the jet outlet 71, the fluid located below the jet outlet 71 can directly impact the dirt in the drain pipe 6 and push the dirt along the rear section of the connecting section 61 towards the inner cavity of the drain 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 drain section 62. This also effectively avoids the waste of the kinetic energy of the pressurized fluid, thereby improving the effect of the jet assembly 7 in pushing the dirt to flow and preventing the dirt from clogging the drain pipe 6.

[0180] like Figure 13 and Figure 14 As shown, in one embodiment of this disclosure, multiple jet outlets 71 are provided, and the multiple jet outlets 71 are configured to be uniformly arranged on the end face of the jet member 72. Since multiple jet outlets 71 are provided and the multiple jet outlets 71 are uniformly arranged on the end face of the jet member 72, the pressurized fluid flowing out from each jet outlet 71 can jointly push the dirt, making the dirt in the drain pipe 6 have a larger force-bearing surface and more balanced force. This allows dirt in all circumferential directions to be pushed by the pressurized fluid to flow towards the outlet of the drain pipe 6, avoiding the situation where only some dirt accelerates the flow while others do not, resulting in the deposition of solid dirt in the drain pipe 6.

[0181] Specifically, such as Figure 13 and Figure 14 As shown, in one embodiment of this disclosure, the jet outlet 71 includes a central outlet 711 located at the center of the jet member 72 and edge outlets 712 disposed at the edge of the jet member 72. At least two edge outlets 712 are provided, located at least on both sides of the central outlet 711, and each edge outlet 712 is configured to surround the central outlet 711. Thus, the pressurized fluid ejected from the central outlet 711 can impact the central portion of the dirt inside the drain pipe 6, and the pressurized fluid ejected from the edge outlets 712 can impact the circumferential edge portion of the dirt inside the drain pipe 6. This ensures that the dirt at both the center and edge positions inside the drain pipe 6 can be pushed and accelerated by the pressurized fluid, resulting in a more balanced force on the dirt inside the drain pipe 6, which is beneficial for dirt flow and prevents solid waste from depositing inside the drain pipe 6.

[0182] like Figure 13 and Figure 14As shown, in one embodiment of this disclosure, the size of the central outlet 711 is configured to be larger than the size of each edge outlet 712. In this way, the thrust on the dirt in the central part of the sewage pipe 6 can be greater than the thrust on the dirt in the edge part, thereby making the flow velocity of the dirt in the central part faster than that of the dirt in the edge part, thereby effectively improving the kinetic energy utilization efficiency of the pressurized fluid and reducing kinetic energy waste.

[0183] In another embodiment of this disclosure, the inner diameter of the central outlet 711 is configured to be equal to the size of each edge outlet 712. In this way, the thrust on the dirt in the central part of the sewage pipe 6 is more balanced with the thrust on the dirt in the edge part, thereby enabling the dirt in the sewage pipe 6 to flow faster as a whole, avoiding the slow flow speed of some dirt, and preventing solid dirt in some dirt from depositing in the sewage pipe 6.

[0184] It is understandable that, such as Figure 5 As shown, in one embodiment of this disclosure, the central axis of the central outlet 711 is configured to be parallel to the central axis of the drain section 62. Because the central axis of the central outlet 711 is parallel to the central axis of the drain section 62, the pressurized fluid flowing out of the central outlet 711 can flow along the central axis of the drain section 62. During the process of this pressurized fluid propelling the dirt through the drain pipe 6, the dirt is prevented from rotating within the drain section 62 as much as possible, thereby allowing the dirt to be discharged from the drain section 62 as quickly as possible.

[0185] like Figure 14 As shown, in one embodiment of this disclosure, the cross-sectional shape of the jet outlet 71 is configured as circular. Because the cross-sectional shape of the jet outlet 71 is circular, the pressure is more uniform when the pressurized fluid flows out of the circular jet outlet 71, and the flow velocity attenuation is also minimal.

[0186] like Figure 5 As shown, in one embodiment of this disclosure, the jet assembly 7 extends along a first direction. Since the jet assembly 7 itself 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.

[0187] To control the operation of the wastewater discharge assist device 70 of this disclosure, the control unit of this disclosure is configured to activate the wastewater discharge assist device 70 during the process of wastewater discharge from the wastewater tank 3, at the same time as the start of wastewater discharge, or before wastewater discharge. Thus, when the control unit activates the wastewater discharge assist device 70 during the process of wastewater discharge from the wastewater tank 3, at the same time as the start of wastewater discharge, or before wastewater discharge, the wastewater discharge assist device 70 can continuously provide a pressure source to the area of ​​the connecting section 61 through the output port 701. This ensures that during the process of wastewater discharge from the cleaning equipment 90, the flow velocity of the wastewater in the wastewater discharge pipe 6 is increased under the action of the wastewater discharge assist device 70, completely preventing solid waste from accumulating in the wastewater discharge section 62 and avoiding blockage of the wastewater discharge pipe 6.

[0188] In another embodiment of this disclosure, the control unit activates the drainage assist device 70 when the dirt in the drainage tank 3 reaches a predetermined level. That is, the drainage assist device 70 only activates when there is a large amount of dirt in the drainage tank 3, the dirt discharge is slow, and solid waste may accumulate in the drainage section 62. This allows the drainage assist device 70 to be activated before potential blockage occurs in the drainage pipe 6, preventing blockage. When drainage is smooth, the drainage assist device 70 is not needed, effectively saving its operation, conserving resources, and reducing energy waste.

[0189] In a specific embodiment of this disclosure, EV2 (the solenoid valve controlling the water supply to the jet assembly) is opened for 10 seconds. The 10 seconds is calculated based on a 1.5m drain pipe with an inner diameter of 32mm and a length of 1.5m. The water flow rate of the jet assembly is 8L / min (the minimum flushing flow rate for laboratory testing). The amount of water required to push the dirt from the head to the tail of the drain pipe is approximately the volume of the entire drain pipe {3.14*(32 / 2)^2*1500}=1,205,760mm^3. The calculation time is (1,205,760 / 8000000*60)=9.04s. Considering the length of the drain pipe, the opening time of the jet assembly is set to 10 seconds, that is, the single flushing time is 10 seconds. It is disconnected after 12 seconds.

[0190] Open the drain plate and simultaneously open the jet component. If the drain plate is not detected to be open on the first attempt, close the jet component. At this time, the jet component works for the first duration. It continues to work for the second duration until the drain plate is detected to be open on the next two attempts. The first duration + the second duration = 10 seconds.

[0191] like Figures 10 to 12As shown, in one embodiment of this disclosure, the cleaning base station 10 includes a self-cleaning component 5 located in the drain trough 3. The self-cleaning component 5 is configured to be located at a position higher than the end face of the dirt-receiving port 321. The self-cleaning component 5 is configured to output cleaning fluid into the inner cavity of the dirt-receiving portion 31 and / or the dirt-receiving portion 32.

[0192] Thus, during the operation of the cleaning base station 10 disclosed herein, after the dirt discharged by the cleaning equipment 90 is discharged into the drain trough 3 and then discharged from the drain pipe 6, the self-cleaning component 5 can output cleaning fluid into the inner cavity of the dirt-containing part 31 and / or the dirt-receiving part 32, thereby cleaning the inner wall of the dirt-containing part 31 and / or the dirt-receiving part 32 and preventing dirt from remaining on the inner wall of the dirt-containing part 31 and / or the dirt-receiving part 32. Moreover, since the drain trough 3 mainly uses the dirt-receiving part 32 to receive dirt from the cleaning equipment 90, and the self-cleaning component 5 is located above the end face of the dirt-receiving port 321, and the dirt-receiving part 32 is lower than the dirt-containing part 31, when the self-cleaning component 5 cleans the drain trough 3, it can thoroughly clean the dirt-receiving part 32, preventing cleaning dead corners from appearing in the drain trough 3.

[0193] like Figure 10 As shown, in one embodiment of this disclosure, the self-cleaning component 5 is located at the top of the drain tank 3. The self-cleaning component 5 is configured to output cleaning fluid from the top of the dirt-containing part 31 to the inner cavity of the dirt-containing part 31, and to output cleaning fluid from the top of the dirt-containing part 31 to the top and inner cavity of the dirt-receiving part 32. Thus, during the operation of the cleaning base station 10 of this disclosure, after the dirt discharged by the cleaning device 90 is discharged into the drain tank 3 and then discharged from the drain pipe 6, the self-cleaning component 5 can output cleaning fluid from the top of the dirt-containing part 31 to the inner cavity of the dirt-containing part 31, and from the top of the dirt-containing part 31 to the top and inner cavity of the dirt-receiving part 32, thereby cleaning the inner cavities of the dirt-containing part 31 and the dirt-receiving part 32, preventing dirt residue from remaining on the inner cavities of the dirt-containing part 31 and the dirt-receiving part 32, ensuring that the drain tank 3 of this disclosure is clean and odorless, thereby effectively improving the user experience.

[0194] Furthermore, since the self-cleaning component 5 can output cleaning fluid from the top of the dirt-containing part 31 to the inner cavity of the dirt-containing part 31 and the inner cavity of the dirt-collecting part 32, there is no need to set up separate cleaning mechanisms for the dirt-containing part 31 and the dirt-collecting part 32. This can effectively simplify the water channel structure of the cleaning base station 10 of this disclosure and promote the miniaturization of the cleaning base station 10 of this disclosure.

[0195] like Figure 10 , Figure 15 , Figure 16 , Figure 23As shown, in one embodiment of this disclosure, the self-cleaning component 5 includes a dirt-containing cleaning element 51, a dirt-receiving cleaning element 52, and an inlet pipe 53. The dirt-containing cleaning element 51 is disposed at the top of the inner cavity of the dirt-containing portion 31 and is configured to output cleaning liquid into the inner cavity of the dirt-containing portion 31. The dirt-receiving cleaning element 52 is disposed at the top of the inner cavity of the dirt-receiving portion 32 and is configured to output cleaning liquid into the inner cavity of the dirt-receiving portion 32. The inlet pipe 53 communicates with the dirt-containing cleaning element 51 and the dirt-receiving cleaning element 52. The cleaning liquid flowing into the inlet pipe 53 is configured to partially flow into the dirt-containing cleaning element 51 and partially flow into the dirt-receiving cleaning element 52.

[0196] Thus, during the operation of the cleaning base station 10 of this disclosure, the cleaning fluid flowing into the inlet pipe 53 is configured such that part of it flows into the contaminant-containing cleaning component 51 and part of it flows into the contaminant-receiving cleaning component 52. The cleaning fluid flowing into the contaminant-containing cleaning component 51 can be output from the top of the inner cavity of the contaminant-containing part 31 to the inner cavity of the contaminant-containing part 31, thereby cleaning the inner cavity of the contaminant-containing part 31. The cleaning fluid flowing into the contaminant-receiving cleaning component 52 can be output from the top of the inner cavity of the contaminant-receiving part 32 to the inner cavity of the contaminant-receiving part 32, thereby cleaning the inner cavity of the contaminant-containing part 31. In this way, only one inlet pipe 53 is needed to provide cleaning fluid to both the contaminant-containing cleaning component 51 and the contaminant-receiving cleaning component 52, thereby effectively simplifying the water circuit structure of the cleaning base station 10 of this disclosure.

[0197] Specifically, such as Figure 10 As shown, in one embodiment of this disclosure, an inlet chamber 54 communicating with an inlet pipe 53 is provided on the outer wall of the top of the dirt-containing part 31; wherein, the dirt-containing cleaning member 51 is configured to be disposed at a position corresponding to the inlet chamber 54 and communicate with the inlet chamber 54; the dirt-containing cleaning member 52 includes a drain section 521 and an inlet section 522, the drain section 521 is used to output cleaning liquid into the inner cavity of the dirt-containing part 32; the inlet section 522 is configured to communicate with the inlet chamber 54 and the drain section 521.

[0198] During the operation of the cleaning base station 10 disclosed herein, the cleaning fluid flowing into the inlet pipe 53 will enter the inlet chamber 54. Part of the cleaning fluid in the inlet chamber 54 will flow into the dirt-containing cleaning component 51, and the remaining part of the cleaning fluid in the inlet chamber 54 will flow along the inlet section 522 to the outlet section 521, thereby achieving the purpose of simultaneously providing cleaning fluid to the dirt-containing cleaning component 51 and the outlet section 521. The overall inlet structure is simple, and the flow of cleaning fluid is relatively smooth.

[0199] like Figure 10As shown, in one embodiment of this disclosure, a cover plate 55 is provided on the outer wall of the dirt-containing part 31. The cover plate 55 is fastened to the outer wall of the dirt-containing part 31 and forms a liquid inlet cavity 54 with the outer wall of the dirt-containing part 31. The liquid inlet pipe 53 is provided on the cover plate 55. In this way, the liquid inlet cavity 54 can be formed between the cover plate 55 fastened to the outer wall of the dirt-containing part 31 and the dirt-containing part 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.

[0200] Specifically, such as Figure 10 As shown, in one embodiment of this disclosure, a through hole 56 is provided on the outer wall of the dirt-containing part 31 at the position corresponding to the liquid inlet chamber 54. The liquid inlet chamber 54 is configured to communicate with the dirt-containing cleaning member 51 through the through hole 56. In this way, when the cleaning liquid flows from the liquid inlet pipe 53 into the liquid inlet chamber 54, it can flow through the through hole 56 to the dirt-containing cleaning member 51, that is, to the top of the inner cavity of the dirt-containing part 31, thereby cleaning the inner cavity of the dirt-containing part 31.

[0201] like Figure 10 As shown, in one embodiment of this disclosure, the dirt-containing portion 31 includes a first portion 311 located above and a second portion 312 located below. 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 a cross-sectional area increasing from top to bottom. The dirt-containing cleaning member 51 is disposed at the center 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.

[0202] Since the first part 311 of the dirt-containing part 31 has a gradually expanding structure with a cross-sectional area increasing from top to bottom, and the dirt-containing cleaning component 51 is located at the center of the inner cavity of the first part 311 of the dirt-containing part 31, when the dirt-containing cleaning component 51 outputs cleaning liquid radially to all directions, it can clean all circumferential areas of the inner cavity of the dirt-containing part 31, avoiding cleaning dead corners in the dirt-containing part 31.

[0203] like Figure 9 As shown, in one embodiment of this disclosure, the top of the dirt-receiving portion 32 is configured to extend outward from the dirt-containing portion 31 to form a dirt-receiving port 321 for docking with the drain port 93 of the cleaning device 90. The dirt-receiving cleaning member 52 is configured to at least partially surround the circumferential sidewall of the dirt-receiving port 321 and to output cleaning fluid circumferentially from at least a portion of the dirt-receiving port 321. In this way, since the dirt-receiving cleaning member 52 at least partially surrounds the circumferential sidewall of the dirt-receiving port 321 and outputs cleaning fluid circumferentially from at least a portion of the dirt-receiving port 321, the dirt-receiving cleaning member 52 can clean at least a portion of the circumferential sidewall of the dirt-receiving portion 32, reducing dirt residue on the circumferential sidewall of the dirt-receiving portion 32 and reducing the odor formed by dirt residue in the cleaning base station 10 of this disclosure.

[0204] Specifically, such as Figure 7 As shown, in one embodiment of this disclosure, the soil-receiving portion 32 includes an enclosing wall 322 on the side away from the soil-containing portion 31. The enclosing wall 322 is configured to extend obliquely downward from the top of the soil-receiving portion 32 to abut against a corresponding position of the soil-containing portion 31. The soil-receiving portion 32 also includes a first sidewall 323 and a second sidewall 324 located on both sides of the enclosing wall 322. The first sidewall 323, the second sidewall 324, and the enclosing wall 322 are configured to enclose the soil-receiving portion 32 on the soil-containing portion 31. The soil-receiving cleaning member 52 is configured to be located on the top of the first sidewall 323, the second sidewall 324, and the enclosing wall 322, and is configured to output cleaning fluid downward from the top of the first sidewall 323, the second sidewall 324, and the enclosing wall 322.

[0205] In this way, the dirt-receiving cleaning component 52 can output cleaning fluid 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 residue on the first side wall 323, the second side wall 324, and the enclosing wall 322, and minimizing the odor caused by dirt residue in the cleaning base station 10 of this disclosure.

[0206] Furthermore, such as Figure 7 As shown, in one embodiment of this disclosure, the end face of the dirt-collecting port 321 is configured to extend horizontally or inclined downward from the position connected to the dirt-collecting portion 31; the dirt-collecting cleaning member 52 is configured to be arranged along the end face of the dirt-collecting port 321. Because the dirt-collecting cleaning member 52 is arranged along the end face of the dirt-collecting port 321, the cleaning fluid output by the dirt-collecting cleaning member 52 can flow downward from the end face of the dirt-collecting port 321, avoiding cleaning dead corners in the dirt-collecting portion 32.

[0207] like Figures 10 to 12 As shown, in one embodiment of this disclosure, the drain tank 3 includes a dirt-receiving portion 32 with a dirt-receiving port 321, which is configured to connect to a drain port 93 of a cleaning device 90; a dirt-receiving cleaning component 52 is disposed around the dirt-receiving port 321 and is configured to output cleaning fluid into the inner cavity of the dirt-receiving portion 32; the dirt-receiving cleaning component 52 includes an inlet section 522 and a drain section 521, which is configured to communicate with the inlet section 522 and is disposed at a position lower than the inlet section 522; the cleaning fluid is configured to flow through the inlet section 522 to the drain section 521 and is configured to flow through the drain section 521 to the inner cavity of the dirt-receiving portion 32.

[0208] Thus, during the operation of the cleaning base station 10 of this disclosure, the dirt discharged from the drain port 93 of the cleaning device 90 is discharged from the drain port 321 of the dirt-receiving part 32 into the drain tank 3, and then discharged from the drain pipe 6. The dirt-receiving cleaning component 52 can then output cleaning fluid into the inner cavity of the dirt-receiving part 32 to clean it. Since the dirt-receiving cleaning component 52 is arranged around the drain port 321, it can clean the inner cavity of the dirt-receiving part 32 when outputting cleaning fluid, preventing dirt from remaining on the inner cavity of the dirt-receiving part 32, ensuring that the dirt-receiving part 32 of this disclosure is clean and odorless, thereby effectively improving the user experience.

[0209] Furthermore, since the contamination-collecting cleaning component 52 includes an inlet section 522 and a drain section 521, with the drain section 521 connected to the inlet section 522 and positioned below the inlet section 522, the cleaning fluid can naturally flow from the inlet section 522 to the drain section 521 under its own gravity, and then flow through the drain section 521 to the inner cavity of the contamination-collecting part 32. No external power is required for the flow of the cleaning fluid, thus eliminating the need for a power source for the contamination-collecting cleaning component 52. This effectively simplifies the water path structure of the cleaning base station 10 of this disclosure and promotes the miniaturization of the cleaning base station 10 of this disclosure.

[0210] Furthermore, such as Figure 12 As shown, in one embodiment of this disclosure, the two ends of the inlet section 522 are respectively connected to the two ends of the outlet section 521, and the inlet section 522 and the outlet section 521 are constructed to form a ring structure. Since the two ends of the inlet section 522 are respectively connected to the two ends of the outlet section 521, and the inlet section 522 and the outlet section 521 form a ring structure, the cleaning fluid entering the inlet section 522 will be divided into two parts, flowing to the two ends of the outlet section 521 respectively, and then flowing along the outlet section 521 until it reaches the middle of the outlet section 521. Furthermore, during the flow of the cleaning fluid along the outlet section 521, a portion will flow out from the outlet section 521 into the inner cavity of the dirt-collecting part 32, thereby cleaning the inner cavity of the dirt-collecting part 32. Because the cleaning fluid flows into the outlet section 521 from both ends, not only is the required path of the cleaning fluid shortest and the flow time shortest, but the water pressure loss of the cleaning fluid is also minimal.

[0211] like Figure 7 and Figure 12As shown, in one embodiment of this disclosure, the soil-receiving portion 32 includes an enclosing wall 322, which is configured to extend downward at an angle from the top of the soil-receiving portion 32 to form a drain surface 325. The soil-receiving portion 32 also includes a first sidewall 323 and a second sidewall 324 located on both sides of the enclosing wall 322. The first sidewall 323, the second sidewall 324, and the enclosing wall 322 are configured to enclose the soil-receiving portion 32. The drain section 521 is configured to extend along the top of the first sidewall 323, the enclosing wall 322, and the second sidewall 324. The cleaning liquid is configured to flow out from the drain section 521 at positions corresponding to the first sidewall 323, the enclosing wall 322, and the second sidewall 324. Since the drainage section 521 extends along the top of the first sidewall 323, the enclosing wall 322, and the second sidewall 324, the cleaning liquid flows out from the drainage section 521 at the positions corresponding to the first sidewall 323, the enclosing wall 322, and the second sidewall 324. After the cleaning liquid flows out from the drainage section 521 at the positions corresponding to the first sidewall 323, the enclosing wall 322, and the second sidewall 324, it can clean the first sidewall 323, the enclosing wall 322, and the second sidewall 324, avoiding the residue of dirt on the first sidewall 323, the second sidewall 324, and the enclosing wall 322 of the dirt-bearing part 32, and minimizing the odor caused by dirt residue in the cleaning base station 10 of this disclosure.

[0212] like Figure 9 As shown, in one embodiment of this disclosure, the drain trough 3 includes a dirt-containing portion 31 located within the base 1, and a dirt-receiving portion 32 disposed on the side wall of the dirt-containing portion 31 and communicating with the inner cavity of the dirt-containing portion 31. The top of the dirt-receiving portion 32 is configured to be lower than the top of the dirt-containing portion 31. A drain section 521 is configured to be disposed on the top of the dirt-receiving portion 32, and an inlet section 522 is configured to be disposed on the dirt-containing portion 31 adjacent to the dirt-receiving portion 32. Because the top of the dirt-receiving portion 32 is lower than the top of the dirt-containing portion 31, and the drain section 521 is disposed on the top of the dirt-receiving portion 32, and the inlet section 522 is disposed on the dirt-containing portion 31 adjacent to the dirt-receiving portion 32, the cleaning fluid can flow naturally from the position on the dirt-containing portion 31 adjacent to the dirt-receiving portion 32 to the drain section 521 at the top of the dirt-receiving portion 32 under its own gravity, without the need for external power to flow the cleaning fluid, thereby eliminating the need for a power source for the dirt-receiving cleaning component 52.

[0213] like Figure 12As shown, in one embodiment of this disclosure, an inlet chamber 54 is provided at the top of the dirt-containing portion 31. The inlet chamber 54 is configured to communicate with the middle position of the inlet section 522. The cleaning fluid in the inlet chamber 54 is configured to flow from the middle of the inlet section 522 to both sides. A diverter plate 523 is provided in the flow path from the inlet chamber 54 to the inlet section 522, and the cleaning fluid in the inlet chamber 54 is configured to flow to both sides of the inlet section 522 via both sides of the diverter plate 523. In this way, the cleaning fluid in the inlet chamber 54 can flow from the middle position of the inlet section 522 to both sides of the inlet section 522 via both sides of the diverter plate 523 under the obstruction of the diverter plate 523, thereby naturally achieving the purpose of diverting the cleaning fluid to both ends of the inlet section 522.

[0214] like Figure 10 As shown, in one embodiment of this disclosure, the inlet chamber 54 and the inlet section 522 are higher than the outlet section 521. In this way, the cleaning liquid can be used to flow naturally from the inlet chamber 54 and the inlet section 522 to the outlet section 521 by its own gravity, without the need for external power to flow the cleaning liquid, thereby eliminating the need for a power source for the contaminated cleaning component 52.

[0215] Specifically, such as Figure 12 As shown, in one embodiment of this disclosure, the inlet section 522 is higher than the outlet section 521, and both ends of the inlet section 522 are configured to extend downward along the wall of the dirt-holding portion 31 to communicate with both ends of the outlet section 521. Since both ends of the inlet section 522 extend downward along the wall of the dirt-holding portion 31 to communicate with both ends of the outlet section 521, the cleaning fluid entering the inlet section 522 can be naturally divided into two parts, which flow downward along the wall of the dirt-holding portion 31 to both ends of the outlet section 521, thereby automatically providing cleaning fluid to both ends of the outlet section 521.

[0216] like Figure 10 and Figure 12 , Figure 24 As shown, in one embodiment of this disclosure, the drainage section 521 includes a guide channel 5211 extending circumferentially along the soil-receiving portion 32, and a guide plate 5212 covering the guide channel 5211. The guide plate 5212 and the side of the guide channel 5211 adjacent to the inner cavity of the soil-receiving portion 32 form an overflow port 5213. The cleaning fluid flowing in the guide channel 5211 is configured to flow into the inner cavity of the soil-receiving portion 32 through the overflow port 5213. That is, the guide plate 5212 and the soil-receiving portion 32 form the guide channel 5211, and the side of the guide plate 5212 and the guide channel 5211 adjacent to the inner cavity of the soil-receiving portion 32 forms the overflow port 5213. In this way, as the cleaning fluid flows along the guide channel 5211, a portion of the cleaning fluid can continuously flow into the inner cavity of the soil-receiving portion 32 from the overflow port 5213, thereby cleaning the inner cavity of the soil-receiving portion 32.

[0217] Furthermore, the cleaning fluid entering from both ends of the drainage section 521 converges in the middle of the drainage section 521 and flows from the overflow port 5213 at the corresponding position into the inner cavity of the soil-collecting part 32 to clean the inner cavity of the soil-collecting part 32. Since the guide plate 5212 and the guide channel 5211 both have overflow ports 5213 on the side adjacent to the inner cavity of the soil-collecting part 32, and the overflow ports 5213 form 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 soil-collecting part 32 corresponding to the guide channel 5211 can be cleaned, avoiding cleaning dead corners and preventing dirt from remaining on the inner cavity of the soil-collecting part 32.

[0218] Specifically, in one embodiment of this disclosure, the guide channel 5211 is disposed on the outer side of the inner wall of the dirt-receiving portion 32, and the guide plate 5212 is configured to extend from the top of the dirt-receiving portion 32 toward the inner cavity of the dirt-receiving portion 32, so as to form an overflow port 5213 with the top end face of the dirt-receiving portion 32. That is, as Figure 10 and Figure 12 As shown, the guide channel 5211 is located on the radially outer side of the inner wall of the dirt-receiving part 32, and the guide plate 5212 extends from the top of the dirt-receiving part 32 toward the inner cavity of the dirt-receiving part 32 on the side facing the inner cavity of the dirt-receiving part 32, so as to form an overflow port 5213 with the top end face of the dirt-receiving part 32. In this way, after the liquid level of the cleaning liquid in the guide channel 5211 exceeds the top end face of the dirt-receiving part 32, it can flow out from the overflow port 5213 that opens from the top of the guide channel 5211 toward the inner cavity of the dirt-receiving part 32, and then flow into the dirt-receiving part 32 to clean the dirt-receiving part 32.

[0219] It is understandable that, such as Figure 10 and Figure 12 As shown, the radially outer side of the guide plate 5212 can be sealed with the outer side of the guide groove 5211, which can prevent the cleaning liquid from flowing out from the radially outer side of the guide groove 5211; in another embodiment of this disclosure, the guide plate 5212 and the outer wall surface of the dirt-receiving part 32 can also form the guide groove 521. Further, as... Figure 10 As shown, in one embodiment of this disclosure, the guide channel 5211 is disposed on the outer side of the inner wall of the dirt-receiving portion 32, and the guide plate 5212 is configured to form a downward bending portion on the side facing the inner cavity of the dirt-receiving portion 32. The bending portion and the inner wall of the dirt-receiving portion 32 form an overflow port 5213 with the opening facing downward.

[0220] That is, Figure 10As shown, the guide channel 5211 is located radially outside the dirt-receiving portion 32. The radially outer side of the guide plate 5212 is sealed to the outer side of the guide channel 5211, which can prevent the cleaning fluid from flowing out radially outside the guide channel 5211. The radially inner side of the guide plate 5212 forms a downward bend. The bend and the inner wall of the dirt-receiving portion 32 form an overflow port 5213 with the opening facing downward and towards the inner cavity of the dirt-receiving portion 32. In this way, after the liquid level of the cleaning fluid in the guide channel 5211 exceeds the top end face of the dirt-receiving portion 32, it will flow to the inner side of the bend, and then in the bend... Under the obstruction of the overflow port 5213, the cleaning fluid flows out from the top of the inner cavity of the soil-receiving part 32 and down the inner wall of the soil-receiving part 32. Since the guide plate 5212 and the guide groove 5211 are located on the outside rather than the inside of the inner wall of the soil-receiving part 32, the overflow port 5213 will not protrude from the inner wall of the soil-receiving part 32, thus avoiding the formation of a dead corner below the connection between the overflow port 5213 and the inner wall of the soil-receiving part 32. This allows the cleaning fluid to clean all the inner walls of the soil-receiving part 32 and avoids the formation of cleaning dead corners in the soil-receiving part 32.

[0221] like Figure 12 As shown, in one embodiment of this disclosure, at least two spaced-apart support portions 5214 are provided between the guide plate 5212 and the top end face of the dirt-collecting portion 32, and the guide plate 5212 is at least configured to be supported on the support portions 5214. In this way, the support portions 5214 support the guide portion, ensuring that an overflow port 5213 can be formed between the guide plate 5212 and the top end face of the dirt-collecting portion 32, preventing the guide plate 5212 from deforming and partially blocking the overflow port 5213, thus preventing the cleaning fluid from flowing normally.

[0222] It is understood that the aforementioned guide plate 5212 and the cover plate 55 that participates in forming the liquid inlet cavity 54 can be fixedly connected or integrally formed, and no restriction is imposed here.

[0223] like Figure 10 , Figure 15 and Figure 16 As shown, in one embodiment of this disclosure, the cleaning base station 10 further includes a dirt-containing cleaning component 51, which is disposed at the top of the inner cavity of the dirt-containing portion 31 and is configured to form a liquid outlet channel 511 with the top wall of the dirt-containing portion 31. The cleaning liquid flowing out from the liquid outlet channel 511 is configured to flow downward at least along the inner wall of the dirt-containing portion 31.

[0224] Thus, during the operation of the cleaning base station 10 of this disclosure, after the dirt discharged by the cleaning equipment 90 is discharged into the drain tank 3 and then discharged from the drain pipe 6, the dirt-containing cleaning component 51 can output cleaning fluid from the top of the dirt-containing part 31 into the inner cavity of the dirt-containing part 31, thereby cleaning the inner cavity of the dirt-containing part 31, preventing dirt residue from remaining on the inner cavity of the dirt-containing part 31, ensuring that the drain tank 3 of this disclosure is clean and odorless, thereby effectively improving the user experience. Moreover, since the dirt-containing cleaning component 51 is set at the top of the inner cavity of the dirt-containing part 31 and forms a liquid outlet channel 511 with the top wall of the dirt-containing part 31, the cleaning fluid flowing out from the liquid outlet channel 511 flows down at least along the top wall of the dirt-containing part 31, thereby ensuring that the dirt-containing cleaning component 51 can clean the top of the inner cavity of the dirt-containing part 31, reducing cleaning dead corners in the dirt-containing part 31, especially eliminating cleaning dead corners at the top of the dirt-containing part 31, thereby reducing dirt residue in the inner cavity of the dirt-containing part 31.

[0225] like Figure 10 and Figure 15 As shown, in one embodiment of this disclosure, the outlet of the liquid outlet channel 511 is configured to be located in the circumferential direction of the dirt-holding and cleaning member 51. It is constructed to output cleaning fluid for cleaning the inner wall of the dirt-holding cavity in the circumferential direction of the dirt-holding and cleaning member 51. In this way, the cleaning fluid can be output outward from the circumferential direction of the dirt-holding and cleaning member 51. Furthermore, since the dirt-holding and cleaning member 51 is located at the top of the inner cavity of the dirt-holding portion 31, the cleaning fluid can be output outward from the top circumferential direction of the inner cavity of the dirt-holding portion 31. This ensures that the cleaning fluid can clean all circumferential areas of the inner cavity of the dirt-holding portion 31, avoiding cleaning dead zones, especially at the top of the dirt-holding portion 31, preventing dirt residue in the inner cavity of the dirt-holding portion 31, and ensuring that the dirt-holding portion 31 of this disclosure is clean and odorless.

[0226] Specifically, such as Figure 10 As shown, in one embodiment of this disclosure, the dirt-containing 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 dock with the second portion 312. The size of the first portion 311 is configured to have a gradually expanding structure with an increasing cross-sectional area from top to bottom. The dirt-containing cleaning member 51 is disposed at the center of the inner cavity of the first portion 311 of the dirt-containing portion 31 and is configured to output cleaning liquid along the circumference of the dirt-containing cleaning member 51. Since the size of the first portion 311 of the dirt-containing portion 31 has a gradually expanding structure with an increasing cross-sectional area from top to bottom, when the dirt-containing cleaning member 51 disposed at the center of the inner cavity of the first portion 311 of the dirt-containing portion 31 outputs cleaning liquid along the circumference of the dirt-containing cleaning member 51, it can be ensured that the cleaning liquid at all locations in the circumference can flow down along the inner wall of the dirt-containing portion 31 to clean all locations in the circumference of the inner cavity of the dirt-containing portion 31, further avoiding cleaning dead corners in the dirt-containing portion 31.

[0227] Specifically, such as Figure 10As shown, in one embodiment of this disclosure, the end face of the dirt-holding cleaning member 51 adjacent to the top wall of the dirt-holding portion 31 is configured to form a liquid outlet channel 511 with the top wall of the dirt-holding portion 31; the circumferential edge of the dirt-holding cleaning member 51 is configured to form the outlet of the liquid outlet channel 511. In this way, after the cleaning liquid flows from the through hole 56 on the top wall of the dirt-holding portion 31 into the liquid outlet channel 511 formed by the end face of the dirt-holding cleaning member 51 adjacent to the top wall of the dirt-holding portion 31 and the top wall of the dirt-holding portion 31, it will be output outward along the circumferential edge of the dirt-holding cleaning member into the inner cavity of the dirt-holding portion 31, and the overall water channel structure is relatively simple.

[0228] Specific examples Figure 15 and Figure 16 As shown, in one embodiment of this disclosure, at least two partitions 512 are provided on the end face of the dirt-holding cleaning member 51, and the at least two partitions 512 abut against the top wall of the dirt-holding part 31; and / or, at least two partitions 512 are provided on the top wall of the dirt-holding part 31, and the at least two partitions 512 abut against the end face of the dirt-holding cleaning member 51; the partitions 512 cause the end face of the dirt-holding cleaning member 51 and the top wall of the dirt-holding part 31 to form a liquid outlet channel 511, and the partitions 512 are configured to be spaced apart in the circumferential direction of the liquid outlet channel 511.

[0229] The partition 512 is disposed on either the end face of the dirt-holding cleaning member 51 or the top wall of the dirt-holding part 31, and abuts against the other. Since the partitions 512 are spaced apart in the circumferential direction of the liquid outlet channel 511, the partitions 512 cause the end face of the dirt-holding cleaning member 51 and the top wall of the dirt-holding part 31 to form the liquid outlet channel 511, and form a guide area 5111 in the liquid outlet channel 511, thereby enabling the cleaning liquid to flow within the guide area 5111 formed by the partitions 512.

[0230] Specifically, such as Figure 15 As shown, in one embodiment of this disclosure, the partition 512 is configured to extend radially in the liquid outlet channel 511; the two sidewalls of the partition 512 are configured to intersect in the direction adjacent to the liquid outlet and form the first end of the partition 512. Since the partition 512 extends radially in the liquid outlet channel 511, and the two sidewalls of the partition 512 intersect in the direction adjacent to the liquid outlet and form the first end of the partition 512, i.e., as... Figure 15 As shown, the direction of the partition 512 near the liquid outlet is angular. When the cleaning liquid from the left and right sides of the partition 512 flows along the two walls of the partition 512, a confluence area is generated. The cleaning liquid will flow outward in the entire circumference of the dirt-containing cleaning component 51, and no cleaning dead corner will be generated due to the presence of the partition 512.

[0231] It is understandable that the radial extension of the partition 512 in the liquid outlet channel 511 refers to its extension from the center of the dirt-holding and cleaning member 51 outwards. For example... Figure 15 As shown, the second end of the partition 512 can be arc-shaped, so that the partition 512 as a whole is teardrop-shaped. The second end of the partition 512 can also be other shapes, which are not limited here.

[0232] Specifically, such as Figure 15 As shown, in one embodiment of this disclosure, the first end of the partition 512 is configured to not extend beyond the outlet of the liquid outlet channel 511, and the region in the liquid outlet channel 511 located between the first end of the partition 512 and the outlet forms a confluence region 5112 that communicates with the guide region 5111.

[0233] In this way, the cleaning fluid can first flow along the guide zone 5111 formed by the partition 512, and after flowing out of the guide zone 5111, it can flow to the confluence zone 5112 located between the first end of the partition 512 and the outlet in the liquid outlet channel 511, thereby merging with the cleaning fluid in the adjacent guide zone 5111, ensuring that the cleaning fluid is continuously distributed in all directions of the dirt-containing cleaning component 51 without any leakage, and thus no cleaning dead corners are generated.

[0234] like Figure 15 As shown, in one embodiment of this 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 that is located adjacent to its edge and is configured to extend downward at an incline, and a second inclined surface 516 that is located away from its edge and is configured to extend upward at an incline, the first inclined surface 515 and the second inclined surface 516 being transitionally connected; 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 extend beyond the second inclined surface 516.

[0235] In this way, as the cleaning fluid flows along the second inclined surface 516, the gap between the end face of the stain-holding cleaning component 51 and the inner wall of the stain-holding portion 31 continuously decreases, and the cleaning fluid is compressed. Thus, when the cleaning fluid flows to the guide zone 5111 formed by the partition 512, there will be no interruption of the cleaning fluid flow in the circumference. After the cleaning fluid flows to the first inclined surface 515 at the edge of the stain-holding cleaning component 51, because the downwardly extending first inclined surface 515 conforms to the contour of the top inner wall of the stain-holding portion 31, it ensures that the cleaning fluid can flow towards the inner wall of the stain-holding portion 31 to clean the inner wall of the stain-holding portion 31. The end face of the stain-holding cleaning component 51 can be an arc-shaped curved surface or a straight slope surface; there is no limitation here.

[0236] In one embodiment of this disclosure, the cleaning base station 10 further includes an elastic element. The dirt-holding cleaning element 51 is configured to be pre-pressed against the top wall of the dirt-holding portion 31 by the elastic element. The dirt-holding cleaning element 51 is configured to move away from the top wall of the dirt-holding portion 31 when subjected to an external force greater than a threshold, and to move closer to the top wall of the dirt-holding portion 31 under the action of the elastic element when subjected to an external force less than the threshold. Thus, when no cleaning fluid flows out of the through-hole 56 or the water pressure of the cleaning fluid is low, the dirt-holding cleaning element 51 can move closer to the top wall of the dirt-holding portion 31 under the elastic force of the elastic element, thereby pressing it firmly against the top wall of the dirt-holding portion 31 to seal it. Furthermore, when the water pressure of the cleaning fluid decreases, the dirt-holding cleaning element 51 can move closer to the top wall of the dirt-holding portion 31 under the elastic force of the elastic element, thereby narrowing the liquid outlet channel 511, maintaining continuous flow in the liquid outlet channel 511, and maintaining a certain liquid outlet pressure during liquid outlet, thereby improving the flushing effect of the dirt-holding cleaning element 51.

[0237] When the water pressure of the cleaning fluid flowing out of the through hole 56 is large, exceeding the threshold, the cleaning component 51 can overcome the elastic force of the elastic component and move away from the top wall of the dirt-holding part 31 under the action of the water pressure of the cleaning fluid, naturally opening the liquid outlet channel 511, so that the cleaning fluid can be continuously output along the circumference of the cleaning component 51, so as to ensure that the cleaning fluid water pressure of the dirt-holding part 31 is large, thereby meeting the cleaning needs.

[0238] like Figure 7 and Figure 10 As shown, in one embodiment of this disclosure, the drain tank 3 includes a dirt-receiving portion 32 communicating with the inner cavity of the dirt-receiving portion 31. The dirt-receiving port 321 at the top of the dirt-receiving portion 32 is configured to be lower than the top of the dirt-receiving portion 31. A baffle 33 is provided on the side of the dirt-receiving portion 31 adjacent to the dirt-receiving portion 32. The baffle 33 is configured to extend downward from the top wall of the dirt-receiving portion 31 to a position adjacent to the dirt-receiving port 321. Since the baffle 33 is provided on the side of the dirt-receiving portion 31 adjacent to the dirt-receiving portion 32, and the baffle 33 extends downward from the top wall of the dirt-receiving portion 31 to a position adjacent to the dirt-receiving port 321, the cleaning liquid output by the dirt-receiving cleaning member 51 can be prevented from flowing to the inner wall of the dirt-receiving portion 32 and interfering with the cleaning liquid output by the dirt-receiving cleaning member 52. It can also prevent the cleaning liquid from being splashed out of the dirt-receiving port 321.

[0239] like Figure 3 As shown, in one embodiment of this disclosure, the cleaning base station 10 further includes a blockage sensor 8, which is disposed at the detection position 81 of the sewage tank 3. The blockage sensor 8 is configured to be triggered when a sewage blockage occurs at the detection position 81. The volume of the cleaning base station 10 located below the detection position 81 is configured to be greater than 80% of the volume of the sewage tank 92.

[0240] 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 by the light emitting end is refracted and cannot be reflected back to the light receiving end, thus triggering the detection of liquid signal.

[0241] Assuming the wastewater tank 92 of the cleaning equipment 90 is full and there is no blockage in the drain tank 3, the time required for the wastewater to be drained from the drain tank 3 is t1. During this time t1, the dirt will continuously flow through the blockage sensor 8, and the maximum continuous time for the blockage sensor 8 to sense the liquid signal is t1. When a blockage occurs in the drain tank 3 and the blockage level reaches the blockage sensor 8, the blockage sensor 8 detects the liquid signal. If the continuous time for the liquid level sensor 8 to detect the liquid signal is greater than t1, it can be determined that a blockage has occurred.

[0242] In existing cleaning base stations, the volume of the sewage tank 3 below the detection position 81 is relatively small. When the sewage discharge volume is large, dirt easily accumulates at the detection position 81, but no blockage actually occurs, leading to false alarms. In the operation of the cleaning base station 10 of this 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 connects with the sewage receiving port 321 on the sewage tank 3, allowing dirt from the sewage tank 92 to flow into the sewage tank 3. Since the blockage sensor 8 is located within the sewage tank 3 and can be triggered when the level of dirt in the sewage tank 3 reaches the detection position 81, when the cleaning base station 10 of this disclosure experiences a blockage, causing the level of dirt in the sewage tank 3 to reach the detection position 81, the blockage sensor 8 can be triggered promptly. This allows the cleaning base station 10 to accelerate sewage discharge, thereby removing the dirt blocking the sewage pipe 6 or performing other subsequent steps.

[0243] Since the volume of the cleaning base station 10 located below the detection position 81 is greater than 80% of the volume of the sewage tank 92, even when the sewage discharge is large, dirt is not likely to accumulate at the detection position 81, thus effectively avoiding false alarms.

[0244] Furthermore, in one embodiment of this disclosure, the volume of the drain trough 3 located above the detection position 81 is configured to be greater than the volume of the sewage tank 92.

[0245] In this process, after the cleaning equipment 90 begins to discharge wastewater, if the cleaning base station 10 becomes blocked, the wastewater in the wastewater tank 3 cannot be discharged smoothly. When the wastewater level reaches the detection position 81, the blockage sensor 8 will be triggered in time, allowing the cleaning base station 10 to handle the situation. However, if the cleaning equipment 90 begins to discharge wastewater, and the cleaning base station 10 becomes blocked, the wastewater in the wastewater tank 3 will not be discharged smoothly until the wastewater level reaches the detection position 81. When the cleaning equipment 90 discharges wastewater again, the wastewater in the wastewater tank 3 continues to accumulate, and the blockage sensor 8 will only be triggered when the wastewater level in the wastewater tank 3 reaches the detection position 81. However, the wastewater discharge process of the cleaning equipment 90 will not stop but will continue until the wastewater tank 92 is emptied. At this time, since the volume of the sewage tank 3 above the detection position 81 is greater than the volume of the sewage tank 92, even if the sewage tank 3 just does not reach the detection position 81 at the end of the first sewage discharge and does not trigger the blockage sensor 8, the sewage tank 3 can continue to contain all the dirt in the sewage tank 92 during the second sewage discharge process, and there will be no situation where dirt overflows from the sewage tank 92. This prevents dirt from overflowing from the sewage tank 3 and contaminating the cleaning base station 10, effectively reducing the user's burden and improving the user experience.

[0246] Specifically, in one embodiment of this disclosure, the drain trough 3 includes a dirt-containing portion 31 and a dirt-receiving portion 32 communicating with the inner cavity of the dirt-containing portion 31; the detection position 81 is located in the inner cavity of the dirt-containing portion 31; wherein, the volume above the detection position 81 includes the portion of the dirt-containing portion 31 located above the detection position 81 and the portion of the dirt-receiving portion 32 located above the detection position 81. It is understood that the portion of the dirt-containing portion 31 located above the detection position 81 and the portion of the dirt-receiving portion 32 located above the detection position 81 can both be used to temporarily store dirt, thereby preventing dirt from overflowing from the drain trough 3 and contaminating the cleaning base station 10 in the event of blockage within the cleaning base station 10, and effectively reducing the required volume within the drain trough 3, facilitating the miniaturization of the cleaning base station 10 of this disclosure.

[0247] Specifically, such as Figure 7 As shown, in one embodiment of this disclosure, the top of the dirt-receiving portion 32 is configured to extend outward from the dirt-containing 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 connect with the drain port 93 of the cleaning device 90. The volume above the detection position 81 includes the portion of the dirt-containing portion 31 and the portion of the dirt-receiving portion 32 located from the detection position 81 to the dirt-receiving port 321. Since the volume above the detection position 81 includes the portion of the dirt-containing portion 31 and the portion of the dirt-receiving portion 32 located from the detection position 81 to the dirt-receiving port 321, in the event of a blockage within the cleaning base station 10, it is possible to prevent dirt from overflowing from the dirt-receiving port 321 of the dirt-receiving portion 32 and contaminating the cleaning base station 10.

[0248] like Figure 7 As shown, in one embodiment of this disclosure, the top end face of the sludge receiving port 321 is configured to be lower than the top of the sludge-containing portion 31. When the top end face of the sludge receiving port 321 is lower than the top of the sludge-containing portion 31, the detection position 81 can be set below the top end face of the sludge receiving port 321, and the volume of the position can meet the above requirements, ensuring that the blockage sensor 8 can be triggered normally in case of blockage.

[0249] like Figure 4 and Figure 7 As shown, in one embodiment of this disclosure, the dirt-receiving portion 32 is connected to one side of the dirt-containing portion 31. The dirt-receiving portion 32 has a drain surface 325 extending into communication with the inner cavity of the dirt-containing portion 31. At least a portion of the dirt flowing out from the drain port 93 is configured to flow from the drain surface 325 into the inner cavity of the dirt-containing portion 31. The detection position 81 is configured to be located on the side of the dirt-containing portion 31 away from the drain surface 325.

[0250] Thus, during the operation of the cleaning base station 10 disclosed herein, the discharge surface 325 of the contaminant-receiving section 32 can receive the dirt discharged from the discharge port 93 of the cleaning equipment 90 and guide the dirt discharged from the cleaning equipment 90 into the inner cavity of the contaminant-containing section 31. Since the detection position 81 is located on the side of the contaminant-containing section 31 away from the discharge surface 325, the dirt is less likely to impact the blockage sensor 8 on the detection position 81 during the flow of dirt along the discharge surface 325, thereby reducing the probability of false alarms from the blockage sensor 8.

[0251] Furthermore, in one embodiment of this disclosure, the detection position 81 is configured to be no lower than the bottom end of the drain surface 325. When dirt flows along the drain surface 325 of the dirt-receiving portion 32 into the inner cavity of the dirt-holding portion 31, since the detection position 81 is no lower than the bottom end of the drain surface 325, even if the flow speed is relatively fast during the process of dirt flowing into the inner cavity of the dirt-holding portion 31, it will not directly impact the blockage sensor 8 at the detection position 81, thereby effectively avoiding false alarms from the blockage sensor 8.

[0252] In one embodiment of this 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. Because 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 meets the requirements. This reduces the required volume of the sewage trough 3, facilitating the miniaturization of the cleaning base station 10 of this disclosure, while preventing dirt from overflowing from the sewage trough 3 and contaminating the cleaning base station 10.

[0253] In another embodiment of this 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 tank 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 tank 92, and since the cleaning base station 10 requires a period of time to discharge dirt, the portion of the sewage trough 3 below the detection position 81 can temporarily store dirt during the discharge process. This ensures that after the dirt from the cleaning equipment 90 is quickly discharged into the sewage trough 3, the level of dirt will not reach the detection position 81 if the cleaning base station 10 is not blocked, thus preventing the blockage sensor 8 from being triggered. This prevents the level of dirt from reaching the detection position 81 during each discharge, thus avoiding false alarms from the blockage sensor 8. It is 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.

[0254] In one embodiment of this disclosure, the control unit is configured to issue an alarm message based on an electrical signal triggered by the blockage sensor 8. Thus, when the blockage sensor 8 is triggered, the control unit can promptly issue an alarm message, thereby notifying the user to perform maintenance or other work.

[0255] In one embodiment of this disclosure, if the blockage sensor 8 detects a blockage, self-cleaning is canceled, and a prompt and charging are initiated. In another embodiment of this disclosure, if a blockage occurs, the jet element can be allowed to operate for a period of time (e.g., 3 seconds; within 3 seconds, it can operate at the original water flow rate or by increasing the water flow rate to increase the flushing kinetic energy). This time is related to the volume of the drain tank above the blockage sensor (900 ml) and the flow rate of the jet element (8 L / min to 15 L / min). Water must not overflow. Wait for a period of time (e.g., 5 seconds, as it takes time for the blockage dirt to be drained). If the drain tank is still blocked, self-cleaning is canceled, and a prompt and charging are initiated.

[0256] Understandably, when the cleaning base station 10 of this disclosure is equipped with the aforementioned jet component 7, the cleaning base station 10, while issuing an alarm message, controls the jet component 7 to operate for a period of time to accelerate the flow of dirt in the sewage pipe 6, thereby flushing away the dirt blocking the sewage pipe 6. However, if the blockage is severe and cannot be flushed away, the user must clean it manually.

[0257] In one embodiment of this disclosure, the drain trough 3 is provided with a dirt-receiving port 321 for docking with the drain outlet 93 of the cleaning device 90; and the drain trough 3 is configured to rotate between a first position and a second position. When in the first position, the dirt-receiving port 321 is located on the front side of the tray 2, and when in the second position, the dirt-receiving port 321 is located inside the base 1. Thus, when the cleaning device 90 needs to dock with the cleaning base station 10 for drainage, the drain trough 3 can rotate to the first position, allowing the drain outlet 93 of the cleaning device 90 to dock with the dirt-receiving port 321 of the drain trough 3, and allowing dirt inside the cleaning device 90 to be discharged into the cleaning base station 10 through the dirt-receiving port 321; when drainage is not required, the drain trough 3 can rotate to the second position, allowing the dirt-receiving port 321 to be housed inside the base 1, thereby concealing the dirt-receiving port 321, preventing odor backflow from the drain trough 3, and effectively improving the user experience. Specifically, the rotation of the drain trough 3 can be controlled by a motor or other mechanical transmission device; the specific principle can be found in other existing technologies and will not be elaborated here. In another embodiment, the rotation of the sewage tank 3 can also be achieved by docking the cleaning device 90 with the cleaning base station 10. Specifically, a first trigger can be provided on the base station 10, which has an initial state and a first state. When the cleaning device 90 docks with the base station 10, the cleaning device 90 abuts against the first trigger, causing the first trigger to change from the initial state to the first state, thereby driving the sewage tank 3 to rotate to the first position. When the cleaning device 90 is removed from the base station 10, the first trigger returns from the first state to the initial state, driving the sewage tank 3 to rotate to the second position.

[0258] In one embodiment of this disclosure, the drain trough 3 is provided with a wastewater receiving port 321 for docking with the wastewater outlet 93 of the cleaning equipment 90; and a partition is provided on the wastewater receiving port 321, the partition being configured to open or close the wastewater receiving port 321. Specifically, the partition can rotate or translate relative to the wastewater receiving port 321 to open or close the wastewater receiving port 321, and the specific principle is not limited.

[0259] When the cleaning device 90 needs to dock with the cleaning base station 10 for sewage discharge, the partition can be opened, allowing the sewage outlet 93 of the cleaning device 90 to dock with the sewage receiving outlet 321 of the sewage tank 3. Dirt inside the cleaning device 90 can then be discharged into the cleaning base station 10 through the sewage receiving outlet 321. When sewage discharge is not required, the partition can be used to close the sewage receiving outlet 321, thus concealing it and preventing odor backflow from the sewage tank 3, effectively improving the user experience. Specifically, the movement of the partition can be controlled by a motor or other mechanical transmission device; the specific principle can be found in other existing technologies and will not be elaborated here. In another embodiment, the movement of the partition can also be achieved through the docking of the cleaning device 90 with the cleaning base station 10. Specifically, a second trigger can be installed on the base station 10, having an initial state and a second state. When the cleaning device 90 is connected to the base station 10, the cleaning device 90 abuts against the second trigger, causing the second trigger to change from the initial state to the second state, thereby driving the partition to move to open the dirt receiving port 321. When the cleaning device 90 is removed from the base station 10, the second trigger returns from the second state to the initial state, driving the partition to move to close the dirt receiving port 321.

[0260] like Figure 10 As shown, in one embodiment of this disclosure, the sewage tank 3 includes a dirt-holding section 31, which includes an expanding section with a gradually increasing cross-sectional area from top to bottom and a contracting section with a gradually decreasing cross-sectional area from top to bottom. The expanding section is connected to the top of the contracting section, and the detection position 81 is located at the bottom end of the expanding section where it connects with the contracting section. That is, the detection position 81 is located at the bottom end of the first section 311 where it connects with the contracting section. This can increase the volume below the detection position 81 when a blockage occurs, reducing the probability of false alarms when the drainage speed is slow. At the same time, since the bottom end of the expanding section of the dirt-holding section 31 where it connects with the contracting section is very obvious, it is convenient for staff to install the blockage sensor 8 without having to locate the detection position 81 before installation.

[0261] like Figures 1 to 3 As shown, this disclosure also provides a cleaning system, which includes a cleaning device 90 and a cleaning base station 10. The cleaning device 90 includes a body 91 and a drain outlet 93 disposed on the body 91.

[0262] Application Scenario 1

[0263] This disclosure provides a cleaning base station 10 for use in conjunction with a cleaning device 90 for cleaning operations. The cleaning base station 10 includes a base 1, a tray 2, and a drain trough 3. The base 1 is configured to extend in the height direction and is used to install various functional components required for the cleaning base station 10, such as the drain trough 3. The tray 2 is disposed at the bottom of the base 1 and extends forward horizontally relative to the base 1; the side opposite to the front side is referred to as the rear side. The drain trough 3 includes a dirt-containing portion 31 located within the cleaning base station 10 and a dirt-receiving portion 32 communicating with the inner cavity of the dirt-containing portion 31. The dirt-receiving portion 32 is located in front of the dirt-containing portion 31 and is configured to connect to the side wall of the dirt-containing portion 31 to form a receiving cavity with the dirt-containing portion 31.

[0264] During the operation of the cleaning base station 10 disclosed herein, the cleaning device 90 is placed on the tray 2, and the drain outlet 93 of the cleaning device 90 is located above the dirt-receiving part 32, and the dirt discharged by the cleaning device 90 can be discharged into the drain trough 3. The dirt-receiving part 32 is located in front of the dirt-containing part 31 and is connected to the side wall of the dirt-containing part 31. It is mainly used to receive the dirt discharged by the cleaning device 90 and guide the dirt discharged by the cleaning device 90 into the dirt-containing part 31. The dirt-containing part 31 is set in the base 1 and is mainly used to temporarily store dirt and guide the dirt discharged by the cleaning device 90 into the drain pipe 6 so that the dirt can be discharged to the outside.

[0265] Since the dirt-collecting part 32 is located on the front side of the dirt-holding part 31 and is connected to the side wall of the dirt-holding part 31, protruding forward from the base 1, and the dirt-holding part 31 is located inside the base 1, the layout of the cleaning base station 10 of this disclosure can be effectively optimized, saving space and facilitating the miniaturization of the cleaning base station 10. Furthermore, when the drain trough 3 becomes clogged, the dirt-collecting part 32 and the dirt-holding part 31 can jointly contain the dirt, preventing dirt from overflowing from the drain trough 3. Compared to existing cleaning base stations 10, the overall volume of the drain trough 3 of the cleaning base station 10 of this disclosure is larger, occupying less space, effectively improving the user experience.

[0266] Application Scenario 2

[0267] This disclosure provides a cleaning base station 10 for use with a cleaning device 90 for cleaning operations. 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 configured to extend in the height direction. The tray 2 is located at the bottom of the base 1 and is configured to extend in the horizontal direction. The tray 2 is provided with a roller brush groove 21 for accommodating the 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 disposed on the cleaning base station 10. The drain pipe 6 is configured to communicate with the bottom of the drain trough 3. The drain pipe 6 has at least a drain section 62 extending in the horizontal direction and a connecting section 61 connecting the drain section 62 and the bottom of the drain trough 3. One end of the connecting section 61 is configured to extend towards the bottom of the drain trough 3 to communicate with the bottom of the drain trough 3, and the other end is configured to extend towards the drain section 62 to communicate with the drain section 62. The drain section 62 extends along the first direction.

[0268] During the operation of the cleaning base station 10 of this disclosure, the floor brush assembly 94 of the cleaning device 90 is placed on the tray 2. The drain outlet 93 of the cleaning device 90 discharges dirt into the drain trough 3 inside the base 1. The dirt flows from the bottom of the drain trough 3 into the connecting section 61 of the drain pipe 6, and then flows along the drain section 62. Since the drain section 62 extends along the first direction, the overall width of the cleaning base station 10 can be effectively utilized to arrange the drain section 62, thereby reducing the overall length of the cleaning base station 10 in the second direction. Furthermore, since the drain section 62 extends along the first direction, the dirt only needs to go through one turn at the connecting section 61 during its flow to the drain section 62. The drain section 62 extends in the same direction as the external extension pipe connected to the drain outlet of the base station, thereby effectively reducing the kinetic energy loss of the dirt during the draining process and making the draining smoother.

[0269] Application Scenario 3

[0270] This disclosure provides a cleaning base station 10, including a base 1, a tray 2, and a drain trough 3. The base 1 is configured to extend in the height direction; the tray 2 is located at the bottom of the base 1 and is configured to extend in the horizontal direction; the side of the base 1 on which the tray 2 is located is referred to as the front side, and the side opposite to it is referred to as the rear side; the drain trough 3 includes a dirt-containing part 31 located within the base station and a dirt-receiving part 32 communicating with the inner cavity of the dirt-containing part 31; the dirt-receiving part 32 is configured to have a dirt-receiving port 321 for docking with the drain port 93 of a cleaning device 90; the dirt-receiving part 32 has a drain surface 325, and at least a portion of the dirt flowing in from the dirt-receiving port 321 is configured to be guided from the drain surface 325 to the inner cavity of the dirt-containing part 31; the area on the drain surface 325 corresponding to the drain port 93 is configured to be a flat surface or a continuously smooth curved surface.

[0271] During the operation of the cleaning base station 10 disclosed herein, the cleaning device 90 is placed on the tray 2, the drain port 93 of the cleaning device 90 is located above the dirt-receiving part 32, and the dirt discharged by the cleaning device 90 can be discharged into the drain trough 3. The drain surface 325 of the dirt-receiving part 32 can receive the dirt discharged from the drain port 93 of the cleaning device 90 and guide the dirt discharged by the cleaning device 90 into the inner cavity of the dirt-containing part 31. That is, at least a portion of the dirt flowing out from the drain port 93 can flow from the drain surface 325 into the inner cavity of the dirt-containing part 31. The dirt-containing part 31 is disposed within the base 1 and is mainly used for temporarily storing dirt and guiding the dirt discharged by the cleaning device 90 into the drain pipe 6 so that the dirt can be discharged to the outside. Specifically, since the area on the drain surface 325 corresponding to the drain outlet 93 is constructed as a flat surface or a continuous smooth curved surface, dirt will flow smoothly downwards when it falls from the drain outlet 321 onto the drain surface 325, ensuring that the dirt continues to flow towards the drain pipe 6 with greater kinetic energy. It can also prevent dirt from splashing out of the drain outlet 321 when it falls onto the drain surface 325 and onto the base 1 or tray 2 of the cleaning base station 10. This eliminates the need for users to perform secondary cleaning on the cleaning base station 10, effectively reducing the user's burden and improving the user experience.

[0272] Application Scenario 4

[0273] This disclosure provides a cleaning base station 10 for use in conjunction with a cleaning device 90 for cleaning operations. Specifically, the cleaning base station 10 includes a base 1, a drain trough 3, and a self-cleaning component 5. The base 1 is configured to extend in the height direction. The drain trough 3 includes a dirt-containing portion 31 located within the base 1 and a dirt-receiving portion 32 communicating with the inner cavity of the dirt-containing portion 31. The dirt-receiving portion 32 is configured to be connected to the side wall of the dirt-containing portion 31. The self-cleaning component 5 is located at the top of the drain trough 3 and is configured to output cleaning fluid from the top of the dirt-containing portion 31 to the inner cavity of the dirt-containing portion 31, and to output cleaning fluid from the top of the dirt-containing portion 31 to the top of the dirt-receiving portion 32 and the inner cavity of the dirt-receiving portion 32.

[0274] During the operation of the cleaning base station 10 of this disclosure, the dirt discharged by the cleaning device 90 is discharged into the drain tank 3 and then discharged from the drain pipe 6. The self-cleaning component 5 can output cleaning fluid from the top of the dirt-containing part 31 into the inner cavity of the dirt-containing part 31, and from the top of the dirt-containing part 31 into the top and inner cavity of the dirt-receiving part 32, thereby cleaning the inner cavities of the dirt-containing part 31 and the dirt-receiving part 32, preventing dirt residue from remaining on the inner cavities of the dirt-containing part 31 and the dirt-receiving part 32, ensuring that the drain tank 3 of this disclosure is clean and odorless, thus effectively improving the user experience. Furthermore, since the self-cleaning component 5 can output cleaning fluid from the top of the dirt-containing part 31 into the inner cavity of the dirt-containing part 31 and the inner cavity of the dirt-receiving part 32, there is no need to set up separate cleaning mechanisms for the dirt-containing part 31 and the dirt-receiving part 32, which can effectively simplify the water circuit structure of the cleaning base station 10 of this disclosure and promote the miniaturization of the cleaning base station 10 of this disclosure.

[0275] Application Scenario 5

[0276] This disclosure provides a cleaning base station 10 for use in conjunction with a cleaning device 90 for cleaning operations. Specifically, the cleaning base station 10 includes a base 1, a drain trough 3, and a cleaning component 52. The base 1 is configured to extend in the height direction. The drain trough 3 includes a dirt-receiving portion 32 with a dirt-receiving port 321, which is configured to connect to a drain port 93 of the cleaning device 90. The cleaning component 52 is disposed around the dirt-receiving port 321 and is configured to output cleaning fluid into the inner cavity of the dirt-receiving portion 32. The cleaning component 52 includes an inlet section 522 and a drain section 521. The drain section 521 is configured to communicate with the inlet section 522 and is located at a position lower than the inlet section 522. The cleaning fluid is configured to flow from the inlet section 522 to the drain section 521 and is configured to flow from the drain section 521 to the inner cavity of the dirt-receiving portion 32.

[0277] Thus, during the operation of the cleaning base station 10 of this disclosure, the dirt discharged from the drain port 93 of the cleaning device 90 is discharged from the drain port 321 of the dirt-receiving part 32 into the drain tank 3, and then discharged from the drain pipe 6. The dirt-receiving cleaning component 52 can then output cleaning fluid into the inner cavity of the dirt-receiving part 32 to clean it. Since the dirt-receiving cleaning component 52 is arranged around the drain port 321, it can clean the inner cavity of the dirt-receiving part 32 when outputting cleaning fluid, preventing dirt from remaining on the inner cavity of the dirt-receiving part 32, ensuring that the dirt-receiving part 32 of this disclosure is clean and odorless, thereby effectively improving the user experience.

[0278] Furthermore, since the contamination-collecting cleaning component 52 includes an inlet section 522 and a drain section 521, with the drain section 521 connected to the inlet section 522 and positioned below the inlet section 522, the cleaning fluid can naturally flow from the inlet section 522 to the drain section 521 under its own gravity, and then flow through the drain section 521 to the inner cavity of the contamination-collecting part 32. No external power is required for the flow of the cleaning fluid, thus eliminating the need for a power source for the contamination-collecting cleaning component 52. This effectively simplifies the water path structure of the cleaning base station 10 of this disclosure and promotes the miniaturization of the cleaning base station 10 of this disclosure.

[0279] Application Scenario 6

[0280] This disclosure provides a cleaning base station 10 for use in conjunction with a cleaning device 90 for cleaning operations. Specifically, the cleaning base station 10 includes a base 1, a drain trough 3, and a dirt-holding cleaning component 51. The base 1 is configured to extend in the height direction. The drain trough 3 includes a dirt-holding portion 31 located within the base 1. The dirt-holding cleaning component 51 is disposed at the top of the inner cavity of the dirt-holding portion 31 and is configured to form a liquid outlet channel 511 with the top wall of the dirt-holding portion 31. The cleaning liquid flowing out from the liquid outlet channel 511 is configured to flow downward at least along the inner wall of the dirt-holding portion 31.

[0281] Thus, during the operation of the cleaning base station 10 disclosed herein, the dirt discharged by the cleaning equipment 90 is discharged into the sewage tank 3 and then discharged from the sewage pipe 6. The dirt-containing cleaning component 51 can output cleaning fluid from the top of the dirt-containing part 31 into the inner cavity of the dirt-containing part 31, thereby cleaning the inner cavity of the dirt-containing part 31, preventing dirt from remaining on the inner cavity of the dirt-containing part 31, ensuring that the sewage tank 3 of this disclosure is clean and odorless, thereby effectively improving the user experience.

[0282] Furthermore, since the dirt-holding cleaning component 51 is located at the top of the inner cavity of the dirt-holding part 31 and forms an outlet channel 511 with the top wall of the dirt-holding part 31, the cleaning liquid flowing out from the outlet channel 511 flows downward along the inner wall of the dirt-holding part 31, thereby ensuring that the dirt-holding cleaning component 51 can clean the top of the inner cavity of the dirt-holding part 31, reducing cleaning dead corners in the dirt-holding part 31, thereby reducing the residue of dirt in the inner cavity of the dirt-holding part 31.

[0283] Application Scenario 7

[0284] This disclosure provides a cleaning base station 10 configured to interface with a cleaning device 90, and includes a base 1, a drain trough 3, and a blockage sensor 8. The base 1 is configured to extend in the height direction. The drain trough 3 is provided with a receiving port 321 for interface with a drain outlet 93 of the cleaning device 90. The blockage sensor 8 is disposed at a detection position 81 of the drain trough 3 and is configured to be triggered when a blockage occurs at the detection position 81. The volume of the base station located below the detection position 81 is configured to be greater than 80% of the volume of the wastewater tank 92 of the cleaning device 90.

[0285] During the operation of the cleaning base station 10 of this disclosure, the floor brush assembly 94 of the cleaning device 90 is placed on the tray 2, and the drain outlet 93 of the cleaning device 90 is connected to the collection port 321 on the drain trough 3, allowing the dirt in the wastewater tank 92 to flow into the drain trough 3. Since the blockage sensor 8 is located inside the drain trough 3 and can be triggered when the level of dirt in the drain trough 3 reaches the detection position 81, the blockage sensor 8 can be triggered promptly when the cleaning base station 10 of this disclosure becomes blocked, causing the level of dirt in the drain trough 3 to reach the detection position 81. This facilitates accelerated drainage of the cleaning base station 10, thereby removing the dirt blocking the drain pipe 6 or performing other subsequent steps.

[0286] Since the volume of the cleaning base station 10 located below the detection position 81 is greater than 80% of the volume of the sewage tank 92, even when the sewage discharge is large, dirt is not likely to accumulate at the detection position 81, thus effectively avoiding false alarms.

[0287] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are 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 terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein. The scope of this disclosure is defined by the appended claims.
