Description

Cleaning base station, cleaning device and cleaning system

[0001] The present application claims priority to the Chinese Patent Application No. 202411296230.7, filed on September 14, 2024, and entitled "Cleaning Base Station and Cleaning System", and the Chinese Patent Application No. 202411295640.X, filed on September 14, 2024, and entitled "Cleaning Device", the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of cleaning devices, in particular to a cleaning base station, a cleaning device, and a cleaning system. BACKGROUND

[0003] Environmental sanitation is an important factor affecting the quality of life, therefore, with the continuous improvement of people's requirements for the quality of life, the corresponding requirements for environmental sanitation are also getting higher and higher, so there are many ground cleaning devices, commonly used are dust collectors, sweeping machines and scrubbers, etc. The scrubber is a cleaning machine that cleans the ground, dries the sewage and takes the sewage away from the scene.

[0004] The existing scrubber generally has a solution tank for storing cleaning solution and a sewage tank for collecting sewage after cleaning. In order to pour out the sewage in the sewage tank, the user needs to remove the tank cover of the sewage tank by himself, and then pour out the sewage through the upper end of the opening of the sewage tank. This operation is relatively laborious, and the user may be exposed to dirt, greatly affecting the user's experience.

[0005] Therefore, a cleaning system with a cleaning base station appears on the market. The scrubber can realize the discharge of the sewage in the internal sewage tank by cooperating with the cleaning base station. Some cleaning base stations can also clean the cleaning components such as the scrubber and the cleaning cloth.

[0006] However, the overall layout of the existing cleaning base station is not reasonable enough. In order to be able to dock with the cleaning device, a large space is occupied, which is easy to cause space waste.

[0007] In the existing cleaning base station, a guide part is usually arranged above the dirt containing part and is connected with the discharge port of the recycling barrel of the cleaning equipment, and the dirt containing part is a semi-spherical shape gradually shrinking from top to bottom. When blockage occurs, the dirt fills the dirt containing part from bottom to top. Since the volume of the bottom of the dirt containing part is very small, in order to achieve sufficient dirt containing capacity, the radial dimension of the dirt containing part needs to be set very large. At the same time, since the guide part is located above the dirt containing part, the guide part and the dirt containing part are limited in the height direction when the guide part needs to be connected with the bottom of the recycling barrel of the cleaning machine. Moreover, the space of the guide part and the dirt containing part are independent of each other, and the guide part basically only plays a guiding role and cannot contain dirt when blockage occurs. Therefore, the volume of the existing sewage discharge groove is large, the space occupied by the base station is large, and the blockage capacity of the sewage discharge groove is also small, which seriously affects the user experience.

[0008] In addition, after the existing cleaning equipment discharges the dirt in the sewage barrel, part of the dirt remains in the sewage barrel, which needs to be cleaned by the user, causing inconvenience to the user and easily causing hygiene problems, affecting the user experience. SUMMARY

The tray is arranged at the bottom of the base and extends to the front side in the horizontal direction relative to the base, and the side opposite to the front side is referred to as the rear side. The sewage discharge tank comprises a sewage containing part located in the cleaning base station and a sewage receiving part in communication with the inner cavity of the sewage containing part; the sewage receiving part is located at the front side of the sewage containing part and is configured to be connected to the side wall of the sewage containing part to form a containing cavity together with the sewage containing part.

[0109] In the working process of the cleaning base station of the present disclosure, the cleaning device is placed on the tray, the sewage discharge port of the cleaning device is located above the sewage receiving part, and the sewage discharged by the cleaning device can be discharged into the sewage discharge tank. The sewage receiving part is located at the front side of the sewage containing part and is connected to the side wall of the sewage containing part, mainly used for receiving the sewage discharged by the cleaning device and guiding the sewage discharged by the cleaning device to the sewage containing part; the sewage containing part is arranged in the base and is mainly used for temporarily storing the sewage and guiding the sewage discharged by the cleaning device to the sewage discharge pipeline to discharge the sewage to the outside.

[0110] Since the sewage receiving part is located at the front side of the sewage containing part and is connected to the side wall of the sewage containing part and protrudes to the front side from the base, and the sewage containing part is located in the base, the layout of the cleaning base station of the present disclosure can be effectively optimized, the space is saved, and the miniaturization of the cleaning base station is facilitated. Moreover, when the sewage discharge tank is blocked, the sewage receiving part and the sewage containing part can jointly accommodate the sewage to prevent the sewage from overflowing from the sewage discharge tank. Compared with the existing cleaning base station, the overall volume of the sewage discharge tank of the cleaning base station of the present disclosure is larger and occupies less space, which effectively improves the user experience.

[0111] For the convenience of understanding, the specific structure and working principle of the cleaning base station 10 of the present disclosure will be described in detail below with reference to FIGS. 1-24 in combination with an embodiment. It should be noted that the present disclosure also provides a cleaning base station 10, and in order to keep the text concise, the cleaning system is introduced together when the cleaning base station 10 is described herein.

[0112] As shown in FIGS. 1-6, the present disclosure provides a cleaning base station 10 for cleaning work in cooperation with a cleaning device 90.

[0113] As shown in FIGS. 1 and 2, the cleaning device 90 is used to clean the working surface such as the ground and the carpet, and the cleaning device 90 and the cleaning base station 10 can be mutually docked so that the cleaning device 90 can discharge sewage into the cleaning base station 10, and the cleaning base station 10 can also charge the cleaning device 90, supplement cleaning liquid, etc., which will not be described here.

[0114] Specifically, as shown in FIG. 1 and FIG. 2, the cleaning device 90 at least includes a machine body 91 and a sewage tank 92, and it can be understood that the cleaning device 90 can also include a floor brush assembly 94, a cleaning liquid tank. Among them, the machine body 91 serves as a carrier for mounting various functional elements required by the cleaning device 90.

[0115] The floor brush assembly 94 is arranged at the bottom end of the machine body 91 and is used to clean the working surface such as the ground, carpet or furniture surface. A rotating shaft can be arranged between the floor brush assembly 94 and the machine body 91, and the machine body 91 can rotate relative to the floor brush assembly 94 through the rotating shaft. When the machine body 91 is rotated backward to an inclined position away from the floor brush assembly 94, the user can drag the cleaning device 90 back and forth to clean the working surface. When the machine body 91 is rotated forward from the inclined position away from the floor brush assembly 94 to the upright position, the cleaning device 90 can be parked on the working surface, or as shown in FIG. 1 and FIG. 2, the cleaning device 90 can be placed on the cleaning base station 10. When cleaning the working surface, the floor brush assembly 94 is always attached to the working surface. The floor brush assembly 94 can include a floor brush housing and a floor brush rotatingly connected to the floor brush housing. The floor brush can rotate relative to the working surface to wipe the stains on the working surface. As shown, a sewage suction pipe is arranged in the part of the machine body 91 connected to the floor brush assembly 94, and the bottom end of the sewage suction pipe is in communication with a sewage suction port arranged at the floor brush assembly 94.

[0116] The sewage tank 92 is used to contain the dirt sucked from the working surface, which can be sewage generated during cleaning, or can include various garbage sucked from the working surface. The bottom of the sewage tank 92 is provided with a sewage discharge port 93 and a sewage inlet port. The sewage discharge port 93 of the sewage tank 92 is used to dock with the cleaning base station 10, so as to discharge the dirt in the inner cavity of the sewage tank 92 to the cleaning base station 10.

[0117] Specifically, as shown in FIG. 1 to FIG. 6, the cleaning base station 10 includes a base 1, a tray 2 and a sewage discharge groove 3. The base 1 is configured to extend in the height direction and is used to mount various functional elements required by the cleaning base station 10 such as the sewage discharge groove 3.

[0118] The tray 2 is arranged at the bottom of the base 1 and extends forward relative to the base 1 in the horizontal direction. The side opposite to the front side is referred to as the rear side. The tray 2 is mainly used to carry the floor brush assembly 94 of the cleaning base station 10 when the cleaning device 90 docks with the cleaning base station 10 for sewage discharge, and can also be used to clean the floor brush assembly 94 of the cleaning device 90 and charge the cleaning base station 10. That is, it can be understood that the floor brush assembly 94 is located on the tray 2 when discharging sewage.

[0119] The sewage discharge groove 3 comprises a sewage containing part 31 located in the cleaning base station 10 and a sewage receiving part 32 in communication with the inner cavity of the sewage containing part 31; the sewage receiving part 32 is located at the front side of the sewage containing part 31 and is configured to be connected to the side wall of the sewage containing part 31 to form a containing cavity together with the sewage containing part 31.

[0120] It can be understood that the cleaning base station 10 of the present disclosure is a cleaning base station for sewage discharge by gravity only; in existing cleaning base stations, there are cleaning base stations provided with a sewage suction motor, and when the dirty in the recycling bucket needs to be discharged, the sewage suction motor is started to suck the dirty in the recycling bucket into the base station through negative pressure, in such a cleaning base station, the sewage discharge groove needs to be provided as a containing box, which is different from the structural principle of the cleaning base station for sewage discharge by gravity.

[0121] In the working process of the cleaning base station 10 of the present disclosure, the cleaning equipment 90 is placed on the tray 2, the sewage discharge port 93 of the cleaning equipment 90 is located above the sewage receiving part 32, and the dirty discharged by the cleaning equipment 90 can be discharged into the sewage discharge groove 3. The sewage receiving part 32 is located at the front side of the sewage containing part 31 and is connected to the side wall of the sewage containing part 31, mainly used for receiving the dirty discharged by the cleaning equipment 90 and guiding the dirty discharged by the cleaning equipment 90 into the sewage containing part 31; the sewage containing part 31 is arranged in the base 1 and mainly used for temporarily storing the dirty and guiding the dirty discharged by the cleaning equipment 90 into the sewage discharge pipeline 6 to discharge the dirty to the outside.

[0122] Since the sewage receiving part 32 is located at the front side of the sewage containing part 31 and is connected to the side wall of the sewage containing part 31, it protrudes from the base 1 to the front side, so that the sewage receiving part 32 which is in butt joint with the cleaning equipment 90 is located outside the cavity of the base 1 (the base 1 has a front wall 11 and a rear wall 12, the front wall 11 and the rear wall 12 are arranged in the second direction, the front wall 11, the rear wall 12 and the side wall connecting the front wall 11 and the rear wall 12 form the cavity of the base 1, and the sewage receiving part 32 is located outside the front wall 11 of the base 1), and the sewage containing part 31 is located inside the cavity of the base 1 (the sewage containing part 31 is located inside the front wall 11 of the base 1), so that the sewage receiving part 32 basically does not occupy the inner cavity of the base 1, on the one hand, it can reduce the thickness of the base 1, on the other hand, it releases the volume of the sewage containing part 31 in the cavity of the base 1, effectively optimizes the layout of the cleaning base station 10 of the present disclosure, saves space and is conducive to the miniaturization of the cleaning base station 10. Moreover, in the case of blockage of the sewage discharge groove 3, the sewage receiving part 32 and the sewage containing part 31 can jointly contain the dirty, avoiding the dirty overflowing from the sewage discharge groove 3. Compared with the existing cleaning base station, the overall volume of the sewage discharge groove 3 of the cleaning base station 10 of the present disclosure is larger and occupies less space, effectively improving the user experience.

[0123] As shown in FIG. 6, in one embodiment of the present disclosure, the tray 2 is provided with a rolling brush groove 21, the axial direction of the rolling brush groove 21 (i.e. the length extension direction of the rolling brush groove 21) is the first direction, the direction perpendicular to the first direction is the second direction, the first direction and the second direction are both in the horizontal plane, and the dirt containing part 31 is configured to have a size in the first direction greater than its size in the second direction. Since the tray of the cleaning base station needs to accommodate the rolling brush of the floor brush assembly of the cleaning device, the length of the cleaning base station in the first direction of the rolling brush groove 21 needs to be at least greater than or equal to the length of the rolling brush groove 21 in the first direction. Since the size of the dirt containing part 31 in the first direction is greater than its size in the second direction, this design of the dirt containing part 31 can make full use of the space of the base station in the axial direction of the rolling brush groove, effectively reduce the thickness of the dirt containing part 31 and the base 1 where it is located, and facilitate the miniaturization of the base station, increase the user acceptance and favorability, so as to facilitate the arrangement of the cleaning base station 10 of the present disclosure.

[0124] As shown in FIG. 3, in one embodiment of the present disclosure, the dirt receiving part 32 is lower than the dirt containing part 31, which can facilitate cleaning of various parts of the dirt discharging groove 3 and prevent the occurrence of cleaning dead angles in the dirt discharging groove 3.

[0125] It can be understood that in the dirt discharging groove 3 of the present disclosure, the dirt receiving part 32 and the dirt containing part 31 can be integrally formed, and are only distinguished as two parts with different functions, or the dirt receiving part 32 and the dirt containing part 31 can be separately processed and then fixedly connected together, and the specific processing process is not limited herein.

[0126] In order to control the operation of the cleaning base station 10 of the present disclosure, the cleaning base station 10 of the present disclosure can further include a control unit, which can be signal connected with various components on the cleaning base station 10 of the present disclosure to control the working state thereof.

[0127] Specifically, as shown in FIGS. 7-10, in one embodiment of the present disclosure, the top of the dirt receiving portion 32 is configured to extend forward from the dirt containing portion 31 to form a dirt receiving opening 321; the opening direction of the dirt receiving opening 321 is configured to be upward, and is configured to be used for docking with the dirt outlet 93 of the cleaning device 90. Since the top of the dirt receiving portion 32 extends forward from the dirt containing portion 31 to form the dirt receiving opening 321 with the opening direction upward, during the operation of the cleaning base station 10 of the present disclosure, when the cleaning device 90 is placed on the tray 2, the dirt outlet 93 of the cleaning device 90 can be conveniently located above the dirt receiving portion 32 and docked with the dirt receiving opening 321; the dirt discharged by the cleaning device 90 can flow into the dirt receiving portion 32 through the dirt receiving opening 321, and then flow into the dirt containing portion 31. As shown in FIGS. 9 and 10, in one embodiment of the present disclosure, the end face of the dirt receiving opening 321 is configured to extend downward from the position connected with the dirt containing portion 31, so that the end face of the dirt receiving opening 321 is configured to be lower than the position connected with the dirt containing portion 31 in the height direction. In this way, in the state that the front side of the dirt receiving opening 321 is inclined downward, when the user places the cleaning device 90 on the tray 2, the user can conveniently adjust the dirt outlet 93 of the cleaning device 90 to be located obliquely above the dirt receiving opening 321, so as to reduce the interference and obstruction during docking, which is conducive to docking the dirt outlet 93 of the cleaning device 90 with the dirt receiving opening 321, and the dirt discharged by the cleaning device 90 can flow into the dirt receiving portion 32 through the dirt receiving opening 321.

[0128] In another embodiment of the present disclosure, the end face of the dirt receiving opening 321 is configured to extend horizontally from the position connected with the dirt containing portion 31, so that the end face of the dirt receiving opening 321 is configured to be flush with the position connected with the dirt containing portion 31 in the height direction. In this way, in the state that the dirt receiving opening 321 extends horizontally, after the user places the cleaning device 90 on the tray 2, the dirt receiving portion 32 can effectively lift the cleaning device 90 of the present disclosure, which can effectively prevent the cleaning device 90 from sliding off from above the dirt receiving portion 32, and ensure that the dirt outlet 93 of the cleaning device 90 is always docked with the dirt receiving opening 321 during the process of discharging dirt by the cleaning device 90, so as to prevent the dirt discharged by the cleaning device 90 from flowing out of the cleaning base station 10 to cause pollution.

[0129] Further, as shown in FIG. 10, in one embodiment of the present disclosure, the plane where the pollution-accepting opening 321 is located is denoted as plane S, and the area of the pollution-accepting portion 31 on the plane S is configured to be smaller than the area of the pollution-accepting opening 321 on the plane S. Since the area of the pollution-accepting portion 31 on the plane S is smaller than the area of the pollution-accepting opening 321 on the plane S, it can be ensured that the area of the pollution-accepting opening 321 can meet the demand, so as to make the area of the pollution-discharging opening 93 of the cleaning device 90 as large as possible, thereby improving the pollution-discharging speed of the cleaning device 90; and moreover, the area of the pollution-accepting portion 31 on the plane S can be reduced, thereby reducing the overall area of the pollution-discharging groove 3, thereby saving the space occupied by the pollution-discharging groove 3, and greatly reducing the overall volume of the base 1.

[0130] Further, as shown in FIG. 10, in one embodiment of the present disclosure, the pollution-accepting portion 32 is configured to have a tapered structure with a decreasing cross-sectional area from top to bottom. Since the pollution-accepting portion 32 is mainly used to accept the dirt and pollution discharged by the cleaning device 90, when the pollution-accepting portion 32 has a tapered structure with a decreasing cross-sectional area from top to bottom, it can be convenient for the pollution-accepting portion 32 to guide the dirt and pollution discharged by the cleaning device 90 into the pollution-accepting portion 31 after accepting the dirt and pollution from the cleaning device 90, and effectively save the space occupied by the pollution-accepting portion 32.

[0131] Specifically, in one embodiment of the present disclosure, the pollution-accepting portion 32 includes a surrounding wall 322 located away from the pollution-containing portion 31, the surrounding wall 322 is configured to extend downward from the top of the pollution-accepting portion 32 to the corresponding position of the pollution-containing portion 31, the distance from the top end to the bottom end of the surrounding wall 322 to the pollution-containing portion 31 gradually decreases; the pollution-accepting portion 32 further includes a first side wall 323 and a second side wall 324 located on both sides of the surrounding wall 322, the first side wall 323, the second side wall 324, and the surrounding wall 322 are configured to form the pollution-accepting portion 32 on the pollution-containing portion 31. The side of the pollution-accepting portion 32 opposite to the surrounding wall 322 can be open for communication with the inner cavity of the pollution-containing portion 31, and the pollution-accepting portion 32 and the pollution-containing portion 31 form a containing cavity. The pollution-containing portion 31 extends to the front side to form a pollution-accepting opening 321 of the pollution-accepting portion 32, and the pollution-accepting portion 32 and the pollution-containing portion 31 are directly communicated, which is beneficial to the modularization of the pollution-accepting portion 32 and the pollution-containing portion 31, and the continuity of the structure is beneficial to the continuity of the pollution discharge, and is beneficial to the gravity discharge of the dirt. Moreover, the pollution-accepting portion 32 is mainly located outside the inner cavity of the base 1 for docking with the pollution discharge opening of the cleaning equipment 90, and the pollution-accepting portion 32 does not occupy the inner cavity volume of the base 1. When the pollution-accepting portion 32 and the pollution-containing portion 31 form a cavity together, the cavity can contain the dirt when the dirt is accumulated from bottom to top, that is, the dirt can be contained by the capacity of the pollution-accepting portion 32 and the pollution-containing portion 31 when the dirt rises to a lower height. At the same time, since the pollution-accepting portion 32 is extended from both sides of the pollution-containing portion 31, the two sides of the pollution-accepting portion 32 need to be docked with the two sides of the pollution-containing portion 31, and the shape of the pollution-containing portion 31 makes the cross-sectional area of the docking position larger, that is, the distance between the first side wall 323 and the second side wall 324 is larger, and as a result, the containing cavity formed by the pollution-containing portion 31 and the pollution-accepting portion 32 has a larger volume. Compared with the prior art which only uses the pollution-containing portion to contain the dirt, the same dirt capacity can be ensured while the volume of the pollution discharge groove is greatly reduced, which is beneficial to the miniaturization of the base station, and increases the acceptance and favorability of users.

[0132] In the pollution-accepting portion 32, the surrounding wall 322 is located away from the pollution-containing portion 31, and the top of the pollution-accepting portion 32 extends downward to the corresponding position of the pollution-containing portion 31, the pollution-accepting portion 32 mainly receives the dirt from the cleaning equipment 90 by the surrounding wall 322, and the surrounding wall 322 can guide the dirt discharged by the cleaning equipment 90 to flow along the surrounding wall 322 to the pollution-containing portion 31. The first side wall 323 and the second side wall 324 are mainly used to prevent the dirt from flowing out of the pollution discharge groove 3 during the process of flowing along the surrounding wall 322.

[0133] Of course, it can be understood that, in the case where the first side wall 323 and the second side wall 324 are configured to be inclined towards the side close to the other side, and the enclosing wall 322, the first side wall 323 and the second side wall 324 as a whole are in the shape of a square funnel, the first side wall 323 and the second side wall 324 can also receive the dirt from the cleaning device 90 and guide the dirt discharged by the cleaning device 90 to flow along the first side wall 323 and the second side wall 324 to the dirt storage portion 31. The enclosing wall 322, the first side wall 323 and the second side wall 324 can be integrally formed, or can be separately formed and then fixedly connected together. The specific processing technology is not limited here.

[0134] As shown in FIG. 5, in one embodiment of the present disclosure, the side of the dirt receiving portion 32 opposite to the enclosing wall 322 is open for communication with the inner cavity of the dirt storage portion 31, and the projection of the dirt receiving portion 32 towards the dirt storage portion 31 does not exceed the maximum diameter of the dirt storage portion 31. Since the side of the dirt receiving portion 32 opposite to the enclosing wall 322 is open for communication with the inner cavity of the dirt storage portion 31, it is convenient for the dirt to flow from the dirt receiving portion 32 to the dirt storage portion 31, and since the projection of the dirt receiving portion 32 towards the dirt storage portion 31 does not exceed the maximum diameter of the dirt storage portion 31, the overall projection of the dirt receiving portion 32 can fall between the regions of the dirt storage portion 31, and the dirt receiving portion 32 and the dirt storage portion 31 will not be relatively misplaced left and right, which is conducive to reducing the size of the base 1 in the axial direction of the roller brush groove 21.

[0135] As described above, the dirt discharge groove 3 includes the dirt storage portion 31 located in the base 1 and the dirt receiving portion 32 in communication with the inner cavity of the dirt storage portion 31; the dirt receiving portion 32 is configured to have a dirt receiving opening 321 for receiving the dirt discharge opening 93 of the cleaning device 90.

[0136] As shown in FIGS. 7 to 10, in one embodiment of the present disclosure, the dirt receiving portion 32 has a dirt discharge surface 325, and at least part of the dirt flowing into the dirt receiving opening 321 is configured to be guided from the dirt discharge surface 325 to the inner cavity of the dirt storage portion 31; the region of the dirt discharge surface 325 corresponding to the dirt discharge opening 93 is configured to be a flat surface or a continuously smooth curved surface.

[0137] In the working process of the cleaning base station 10 of the present disclosure, the cleaning device 90 is placed on the tray 2, the dirt discharge opening 93 of the cleaning device 90 is located above the dirt receiving portion 32, and the dirt discharged by the cleaning device 90 can be discharged into the dirt discharge groove 3. Among them, the dirt discharge surface 325 of the dirt receiving portion 32 can receive the dirt discharged by the dirt discharge opening 93 of the cleaning device 90, and guide the dirt discharged by the cleaning device 90 to flow into the inner cavity of the dirt storage portion 31, that is, at least part of the dirt flowing out of the dirt discharge opening 93 can flow from the dirt discharge surface 325 to the inner cavity of the dirt storage portion 31; the dirt storage portion 31 is arranged in the base 1, mainly for temporarily storing dirt, and guiding the dirt discharged by the cleaning device 90 to flow into the dirt discharge pipeline 6, so that the dirt is discharged to the outside.

[0138] Specifically, since the area on the dirt discharging surface 325 corresponding to the dirt discharging port 93 is configured as a flat surface or a continuous and smooth curved surface, when the dirt falls from the dirt receiving port 321 to the dirt discharging surface 325, it will flow smoothly downward, ensuring that the dirt continues to flow to the dirt discharging pipeline 6 with greater kinetic energy, and can also avoid splashing out of the dirt receiving port 321 when the dirt falls on the dirt discharging surface 325, falling on the base 1 or the tray 2 of the cleaning base station 10, so that the user does not need to clean the cleaning base station 10 again, effectively reducing the user's use burden and improving the user's use experience.

[0139] As shown in FIGS. 9 and 10, in an embodiment of the present disclosure, the dirt receiving part 32 is configured to be located on the front side of the dirt containing part 31, and the top of the dirt receiving part 32 is configured to extend from the dirt containing part 31 to the direction in which the tray 2 is located to form the dirt receiving port 321. Since the dirt receiving part 32 is located on the front side of the dirt containing part 31, and the top of the dirt receiving part 32 extends from the dirt containing part 31 to the direction in which the tray 2 is located to form the dirt receiving port 321, it can be convenient for the dirt discharging port 93 of the cleaning equipment 90 to be located above the dirt receiving part 32 and be connected with the dirt receiving port 321; the dirt discharged by the cleaning equipment 90 can flow into the dirt receiving part 32 through the dirt receiving port 321, and then flow into the dirt containing part 31. Since the dirt receiving part 32 is located on the front side of the dirt containing part 31 and is connected to the side wall of the dirt containing part 31, it protrudes to the front side from the base 1, so that the dirt receiving part 32 is located outside the front wall surface 11 of the base 1, that is, the dirt discharging surface 325 is located outside the front wall surface 11 of the base 1, without occupying the cavity volume of the base 1.

[0140] As shown in FIG. 4, in an embodiment of the present disclosure, in the front-rear direction of the base 1, one end of the dirt discharging surface 325 adjacent to the tray 2 is denoted as end A, and the other end away from the tray 2 is denoted as end B; the line connecting the end A and the end B is configured to have an angle with the central axis of the dirt discharging port 93 less than or equal to 40°. Since the line connecting the end A adjacent to the tray 2 and the end B away from the tray 2 of the dirt discharging surface 325 has an angle with the central axis of the dirt discharging port 93 less than or equal to 40°, it can further ensure that when the dirt falls from the dirt discharging port 93 of the cleaning equipment 90 to the dirt discharging surface 325, it will not have a large impact with the dirt discharging surface 325, avoiding the dirt splashing out of the dirt receiving port 321 when it falls on the dirt discharging surface 325, falling on the base 1 or the tray 2 of the cleaning base station 10, and smoothly flowing downward under the action of gravity, ensuring that the dirt continues to flow to the dirt discharging pipeline 6 with greater kinetic energy, thereby improving the dirt discharging efficiency of the cleaning base station 10 of the present disclosure. As shown in FIG. 4, more specifically, since the dirt discharging surface 325 is used to receive the dirt falling from the dirt discharging port 90 of the cleaning equipment 90, the area of the dirt discharging port 90 projected on the dirt discharging surface 325 in the extension direction of the cleaning equipment 90 is denoted as W, since the dirt discharging surface 325 may be slightly curved, the tangent direction of the center point of W is taken as the reference, and the tangent direction of the center point of W and the vertical direction have an angle not more than 40°.

[0141] Further, as shown in FIG. 4, in one embodiment of the present disclosure, in the front-rear direction of the base 1, the end of the sewage outlet 93 away from the base 1 is denoted as end C, and the end adjacent to the base 1 is denoted as end D; wherein the part between the end C and the end D along the normal projection of the central axis of the sewage outlet 93 is configured to be located between the end A and the end B. Since the normal projection of the part between the front end C away from the base 1 and the rear end D adjacent to the base 1 of the sewage outlet 93 on the central axis of the sewage outlet 93 is located between the above-mentioned end A and end B, it can be ensured that the dirt falling from the sewage outlet 93 of the cleaning device 90 can fall into the area where the sewage surface 325 is located, and will not directly fall into the inner cavity of the sewage holding portion 31 or other positions, thereby avoiding the splashing of the dirt directly falling into the inner cavity of the sewage holding portion 31, and effectively playing the role of the flow guide of the sewage surface 325.

[0142] Further, in one embodiment of the present disclosure, the normal projection of the sewage outlet 93 on the central axis thereof is located within the normal projection range of the sewage surface 325 on the central axis of the sewage outlet 93, so that it can be further ensured that the dirt falling from the sewage outlet 93 of the cleaning device 90 can fall onto the sewage surface 325 and flow obliquely downward along the sewage surface 325, and will not directly fall into the inner cavity of the sewage holding portion 31 or other positions to continue flowing to the sewage pipeline 6 by using kinetic energy.

[0143] As shown in FIG. 4, in one embodiment of the present disclosure, the end D of the sewage outlet 93 along the normal projection on the central axis of the sewage outlet 93 coincides with the bottom end of the sewage receiving portion 32, so that it can not only ensure that the sewage outlet 03 can be projected on the sewage surface 325 to effectively guide the flow of dirt by the sewage surface 325, but also there is no need to set an excessively long sewage surface 325, thereby effectively ensuring the miniaturization of the cleaning base station 10 of the present disclosure.

[0144] As shown in FIG. 7, in one embodiment of the present disclosure, the sewage receiving portion 32 includes a surrounding wall 322 away from the side of the sewage holding portion 31, the inner wall of the surrounding wall 322 is configured as the sewage surface 325; the surrounding wall 322 is configured to extend obliquely downward from the top of the sewage receiving portion 32 to be in abutment with the corresponding position of the sewage holding portion 31; the sewage receiving portion 32 further includes a first side wall 323 and a second side wall 324 located on both sides of the surrounding wall 322, and the first side wall 323, the second side wall 324 and the surrounding wall 322 are configured to surround the sewage receiving portion 32 on the sewage holding portion 31. Since the inner wall of the surrounding wall 322 can be used as the sewage surface 325, it is not necessary to separately provide the sewage surface 325 in the sewage receiving portion 32, thereby effectively saving the materials required for processing the sewage receiving portion 32.

[0145] Further, in one embodiment of the present disclosure, the central axis of the pollution outlet 93 is configured to be located between the first side wall 323 and the second side wall 324. That is, the central axis of the pollution outlet 93 can be entirely located on the enclosing wall 322, so that it can be further ensured that the dirt falling from the pollution outlet 93 of the cleaning device 90 can all fall on the enclosing wall 322 and flow obliquely downward along the enclosing wall 322, without directly falling into the inner cavity of the dirt container 31 or other positions, avoiding splashing of the dirt directly falling into the inner cavity of the dirt container 31, and also avoiding the dirt from flowing further to the pollution pipeline 6 by kinetic energy.

[0146] As shown in FIG. 10, in one embodiment of the present disclosure, the outlet of the pollution groove 3 is provided with an end E located at the front side and an end F located at the rear side, and the extension line of the AB two points is located between the end E and the end F of the pollution groove 3. In this way, the dirt discharged from the pollution outlet 93 can directly fall on the outlet of the pollution groove 3 after passing through the pollution surface 325 of the dirt receiving portion 32, so as to minimize the obstruction on the pollution path, and the dirt discharged later can also impact the dirt discharged earlier by gravity, which is more conducive to the discharge of the dirt.

[0147] Further, as shown in FIG. 10, in one embodiment of the present disclosure, the outlet center point G of the pollution groove 3, and the extension line of the AB two points is located between the end E and the center point G, that is, the end B is located above the AE line. In this way, the dirt discharged from the pollution outlet 93 can directly fall on the outlet of the pollution groove 3 after passing through the pollution surface 325 of the dirt receiving portion 32, so as to minimize the obstruction on the pollution path. It can be understood that the extension line of the AB two points between the end E and the center point G includes the case of passing through the end E or the center point G.

[0148] Similarly, as shown in FIG. 10, in one embodiment of the present disclosure, the intersection H of the DF line and the dirt receiving portion 32 or the dirt container 31 is located below the I point, that is, there is no obstruction on the DF line. In this way, it can be further ensured that the dirt discharged from the pollution outlet 93 can directly fall on the outlet of the pollution groove after passing through the pollution surface 325 of the dirt receiving portion 32, so as to minimize the obstruction on the pollution path.

[0149] As shown in FIG. 4, in one embodiment of the present disclosure, the inclination angle of the dirt discharging surface 325 relative to the horizontal plane is configured to decrease continuously from top to bottom. It can be understood that the inclination angle of any point of the dirt discharging surface 325 relative to the horizontal plane is the included angle between the tangent line passing through the point and the horizontal plane, which is at most a right angle. In the embodiment shown in FIG. 4, the inclination angle of the dirt discharging surface 325 relative to the horizontal plane is always an acute angle. In this way, during the process of the dirt discharged by the cleaning device 90 falling onto the dirt discharging surface 325 and flowing along the dirt discharging surface 325, the dirt can be guided to the bottom of the dirt discharging groove 3 under the action of the dirt discharging surface 325, so that the dirt can flow to the bottom of the dirt discharging groove 3 as soon as possible when the dirt flows from the dirt discharging surface 325 to the inner cavity of the dirt containing portion 31, and the dirt will not impact other positions in the inner cavity of the dirt containing portion 31, thereby effectively utilizing the kinetic energy of the dirt and promoting the dirt to be discharged as soon as possible.

[0150] Specifically, as shown in FIG. 4, in one embodiment of the present disclosure, the area of the dirt discharging port 93 is configured to be smaller than the area of the dirt receiving port 321; and in the state that the cleaning device 90 is placed in the cleaning base station 10, the orthogonal projection of the dirt discharging port 93 on the central axis thereof is located in the dirt receiving port 321. In this way, it can be ensured that in the state that the cleaning device 90 is placed in the cleaning base station 10, the dirt discharged by the dirt discharging port 93 of the cleaning device 90 can all fall into the dirt receiving port 321, and will not flow out of the dirt receiving port 321 to pollute the cleaning base station 10, and even if splashing occurs after the dirt falls into the dirt containing portion 32, the dirt is not easy to splash out of the dirt receiving port 321, thereby preventing the dirt from splashing out of the dirt receiving port 321.

[0151] As shown in FIG. 18, in one embodiment of the present disclosure, a filter assembly 326 is arranged in the inner cavity of the dirt containing portion 32, the filter assembly 326 is arranged in the dirt receiving port 321 and is configured to be detachable from the dirt receiving port 321, and the filter assembly 326 is configured to extend downward to form a filter cavity; and in the state that the cleaning device 90 is placed in the cleaning base station 10, the orthogonal projection of the dirt discharging port 93 on the central axis thereof is located in the filter cavity.

[0152] Referring to FIGS. 20 to 22, the filter assembly 326 includes an inlet 3261, a filter portion 3262, and a handle 3263. The inlet 3261 is located at the top end of the filter portion 3262, the filter portion 3262 is annular and surrounds the filter cavity. The inlet 3261 is arranged obliquely, and the plane on which the inlet 3261 is located forms an acute angle with the filter portion 3262. The filter portion 3262 is provided with filter through holes, and the filter portion 3262 includes a bottom wall 3262a, the outer wall surface of the bottom wall 3262a is provided with support ribs 3262b, the support ribs 3262b are provided with at least two support ribs for balance, and the inner wall surface of the bottom wall 3262a is provided with a plurality of guide ribs 3262c.

[0153] The filtering assembly 326 is installed into the dirt discharging groove 3 from the dirt receiving port 321, the inlet 3261 corresponds to the dirt receiving port 321, after the filtering assembly 326 is installed, the plane of the inlet 3261 is parallel to (or coincides with) the plane where the dirt receiving port 321 is located, and the filtering part 3262 which is at an acute angle with the plane where the inlet 3261 is located is installed to adapt to the inclination angle of the dirt discharging surface 325, the bottom wall 3262a is supported on the dirt discharging surface 325, and the support rib 3262b is supported on the dirt discharging surface 325, so as to ensure that the filtering assembly 326 is located at the correct position in the dirt discharging groove 3. In order not to interfere with the guide rib 327 on the dirt discharging surface 325 and to prevent the support rib 3262b from blocking the flow of dirt, the support rib 3262b is formed by extending from the top to the bottom on the outer wall surface of the bottom wall 3262a, after the filtering assembly 326 is installed in the dirt discharging groove 3, the extension direction of the support rib 3262b is consistent with the flow direction of the dirt. 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 dirt discharging surface 325, so that the water flow can easily enter the gap between the bottom wall 3262a and the dirt discharging surface 325 when the dirt discharging groove 3 is flushed, and no dead angle is left for flushing.

[0154] In addition, the plurality of guide ribs 3262c on the inner wall surface of the bottom wall 3262a are formed by extending from the top to the bottom on the inner wall surface of the bottom wall 3262a, which has the same effect as the guide rib 327 on the dirt discharging surface 325, after the filtering assembly 326 is installed in the dirt discharging groove 3, the extension direction of the guide rib 3262c is consistent with the flow direction of the dirt, which guides the flow of the dirt and helps to reduce the rebound kinetic energy of the dirt after falling.

[0155] The top end of the bottom wall 3262a is also provided with a notch 3262d on each side. When the cleaning equipment 90 discharges dirt, the wastewater discharged from the cleaning equipment 90 will spread to both sides, if the water discharge on both sides is not enough, the wastewater will rebound, and the notches 3262d on both sides play a role in quickly discharging the dirt and reducing the rebound of the wastewater.

[0156] The handle 3263 is arranged adjacent to the inlet 3261, and the handle 3263 is rotatably arranged at the inlet 3261. When the handle 3263 is rotated to the plane where the inlet 3261 is located or below the plane where the inlet 3261 is located, the handle 3263 is in a storage state. When the user needs to take out the filtering assembly 326 from the dirt discharging groove 3, the handle 3263 is rotated, and the filtering assembly 326 can be taken out from the base station 10.

[0157] By arranging the filter assembly 326 in the inner cavity of the pollution-accepting part 32, during the operation of the cleaning base station 10 of the present disclosure, the dirt discharged by the cleaning device 90 can all pass through the filter assembly 326, wherein the solid dirt with a larger size is filtered in the filter cavity, and the remaining dirt falls on the dirt-discharging surface 325 and is discharged into the dirt-discharging groove 3. Since the central axis of the dirt-discharging port 93 is projected onto the filter cavity when the cleaning device 90 is placed in the cleaning base station 10, it can be ensured that all the dirt discharged by the cleaning device 90 can be filtered by the filter assembly 326, and the situation that part of the dirt is not filtered by the filter assembly 326 and directly flows into the dirt-discharging groove 3 does not occur.

[0158] As shown in FIG. 10, in an embodiment of the present disclosure, the inclination angle of the dirt-discharging surface 325 relative to the horizontal plane is configured to be smaller than the inclination angle of the side wall of the pollution-accepting part 31 at the position below the enclosing wall 322. Since the inclination angle of the dirt-discharging surface 325 relative to the horizontal plane is smaller than the inclination angle of the side wall of the pollution-accepting part 31 at the position below the enclosing wall 322, the side wall of the pollution-accepting part 31 at the position below the enclosing wall 322 deviates downward from the path in which the dirt-discharging surface 325 extends downward, and when the dirty water discharged by the cleaning device 90 flows downward along the dirt-discharging surface 325 to the pollution-accepting part 31, most of the dirty water does not continue to flow downward along the side wall of the pollution-accepting part 31, but rushes into the middle part of the inner cavity of the pollution-accepting part 31, thereby avoiding the vortex or splashing of the dirty water when the dirty water flows to the pollution-accepting part 31, reducing the impact between the dirt, and ensuring the smooth flow of the dirty water, thereby effectively improving the discharge speed of the dirt from the bottom of the pollution-accepting part 31.

[0159] As shown in FIG. 17, in an embodiment of the present disclosure, at least one guide rib 327 is arranged on the dirt-discharging surface 325, and the guide rib 327 is configured to extend on the dirt-discharging surface 325 in the direction of the flow of the dirt. The extension direction of the guide rib 327 can be parallel to the flow direction of the dirt, or can be arranged at an angle to the flow direction of the dirt. In this way, after the dirt discharged by the cleaning device 90 falls on the dirt-discharging surface 325, the dirt can flow in the extension direction of the guide rib 327, reducing the splashing of the dirt on the dirt-discharging surface 325, and the dirt does not impact on the first side wall 323 and the second side wall 324, thereby effectively reducing the kinetic energy loss of the dirt and ensuring that the dirt flows downward along the dirt-discharging surface 325 as soon as possible.

[0160] As shown in FIG. 3 and FIG. 4, in one embodiment of the present disclosure, the cleaning device 90 is provided with a dirt outlet 93, and a lower cover 95 is arranged at the dirt outlet 93, the lower cover 95 has a first position for closing the dirt outlet 93 and a second position for opening the dirt outlet 93; when the cleaning device 90 is docked with the cleaning base station 10, the lower cover 95 can be rotated from the first position to the second position to open the dirt outlet 93; when the lower cover 95 is in the second position, the lower cover 95 extends into the dirt receiving opening 321 of the dirt receiving part 32 and is located on one side of the dirt discharging surface 325, and the opening angle of the lower cover 95 ranges from 90° to 100°.

[0161] In this way, during the operation of the cleaning device 90 of the present disclosure, the lower cover 95 can be rotated from the first position to the second position to open the dirt outlet 93; when the lower cover 95 is in the second position, the lower cover 95 extends into the dirt receiving opening 321 of the dirt receiving part 32 and is located on one side of the dirt discharging surface 325, and the opening angle of the lower cover 95 ranges from 90° to 100°, so that the dirt in the cleaning device 90 can flow along the lower cover 95, and the lower cover 95 does not hinder the flow of the dirt, thereby ensuring the normal flow of the dirt in the sewage tank 92.

[0162] As shown in FIG. 18, in one embodiment of the present disclosure, the dirt receiving part 32 is arranged on the base 1, and the base 1 is arranged on one side of the tray 2 and provided with a mounting opening 4 for fitting with the dirt receiving opening 321, and the end faces on both sides of the mounting opening 4 are configured to be higher than the end face of the dirt receiving opening 321. When the user places the cleaning device 90 on the tray 2, the cleaning device 90 partially enters the mounting opening 4, and the dirt outlet 93 is located above the dirt receiving opening 321, and since the end faces on both sides of the mounting opening 4 are higher than the end face of the dirt receiving opening 321, the dirt can be effectively prevented from splashing out from both sides of the mounting opening 4 when the cleaning device 90 discharges the dirt, thereby avoiding the pollution of the dirt to the outside and improving the user experience.

[0163] Specifically, as shown in FIG. 4, the lower cover 95 of the sewage outlet 93 of the cleaning device 90 is rotatably connected to the sewage tank 92 at the C end, and when the cleaning device 90 needs to be discharged, the lower cover 95 is unlocked at the D end from the sewage tank 92, and then the lower cover 95 rotates around the rotating shaft at the C end to open the sewage outlet 93. Therefore, during the sewage discharge process of the cleaning device 90, the lower cover 95 of the sewage tank 92 can effectively prevent the dirt from splashing out from the front side, i.e., the side of the sewage tank 92 away from the base 1. Moreover, the lower cover 95 of the sewage tank 92 is rotated and opened by an angle greater than or equal to 90°, so that when the dirt is discharged from the sewage outlet 93, the lower cover 95 will not block the sewage in the sewage discharge path. At the same time, since the lower cover 95 extends into the sewage receiving opening 321 and abuts against the sewage discharge surface 325 after being rotated and opened, if the rotation opening angle of the lower cover 95 is too large, the space required at the sewage discharge surface 325 will also be large, and the overall size of the sewage receiving portion 32 protruding from the outside of the base 1 will be large. Since the cleaning device 90 needs to be placed on the cleaning base 10, if the size of the sewage receiving portion 32 protruding from the outside of the base 1 is too large, the floor brush assembly or the rear side of the body of the cleaning device 90 will interfere with the sewage receiving portion 32 when the cleaning device 90 is placed or taken, which will cause the cleaning base 10 to be redesigned. Therefore, in order to discharge the sewage and facilitate the placement and taking of the cleaning device 90, the rotation opening angle of the lower cover 95 of the sewage tank 92 is not greater than 100°, and the lower cover 95 abuts against the sewage discharge surface 325 in the opened state, so as to ensure the connection and taking of the cleaning device 90 without affecting the sewage discharge.

[0164] Further, in the upright state of the cleaning device 90, the upright body generally forms an acute angle with the floor brush assembly, and the upright body is in a forward-leaning state, and the upright body generally carries components with large weight such as the fan unit and the battery. In order to carry the cleaning device 90 and prevent the cleaning device 90 from leaning forward on the base, as shown in FIG. 18, in an embodiment of the present disclosure, the end faces on both sides of the mounting opening 4 are configured to extend forward to form protrusions 41, and the protrusions 41 are configured to engage the bottom of the body 91 of the cleaning device 90 or the bottom of the sewage tank 92. That is, recesses can be arranged on the bottom of the body 91 or the bottom of the sewage tank 92. Specifically, the bottom of the body 91 or the bottom of the sewage tank 92 is provided with at least two symmetrical recesses. When the user places the cleaning device 90 on the cleaning base 10, the floor brush assembly 94 is carried on the tray 2, and the protrusions 41 on the front side of the mounting opening 4 can be engaged in the recesses on the bottom of the body 91 of the cleaning device 90 or the recesses on the bottom of the sewage tank 92, thereby effectively preventing the cleaning device 90 from sliding off or relatively deflecting from the mounting opening 4, and ensuring the normal discharge of the sewage. As shown in FIG. 18, the protrusions 41 on both sides of the mounting opening 4 are not connected together, but form a gap in the middle region, so as to avoid the protrusions 41 interfering with the sewage outlet 93 of the body 91 or the sewage tank 92, and facilitate the user to place the cleaning device 90 in the mounting opening 4.

[0165] As shown in FIG. 9, in one embodiment of the present disclosure, the dirt containing part 31 is configured to have at least a variable diameter part with size increasing from top to bottom, the dirt receiving part 32 is configured to be connected to at least the variable diameter part and configured to be connected to the side wall of the variable diameter part in transition. The dirt flowing from the dirt receiving part 32 mainly flows to the middle and lower part of the dirt containing part 31, and then is discharged through the dirt discharge pipeline 6. The middle and lower part of the dirt containing part 31 is the effective part for temporarily storing the dirt. The design of the dirt containing part 31 as having at least a variable diameter part with size increasing from top to bottom can effectively expand the volume of the inner cavity of the dirt containing part 31 which mainly temporarily stores the dirt, so as to temporarily store the dirt discharged from the cleaning equipment 90. Even if the dirt containing part 31 is blocked, the dirt mainly accumulates in the middle and lower part of the dirt containing part 31, avoiding the water surface of the dirt being too close to the dirt receiving opening 321. At the same time, the volume of the upper part of the dirt containing part 31 which has less effect on storing dirt can be effectively reduced. In this way, the structure of the dirt containing part 31 is reasonably designed, so that the dirt containing part 31 can maximize the reduction of the occupied space while ensuring sufficient capacity. As mentioned above, the dirt receiving part 32 has a tapered structure with volume decreasing from top to bottom, so as to ensure that the overall width of the dirt discharge groove 3 of the present disclosure will not be greatly increased. Moreover, since the dirt receiving part 32 is connected to at least the variable diameter part and connected to the side wall of the variable diameter part in transition, the connection position of the dirt receiving part 32 and the variable diameter part is located on the extension path of the variable diameter part itself. The dirt receiving part 32 does not extend into the inner cavity of the dirt containing part 31, so the dirt receiving part 32 does not form an obstruction in the inner cavity of the dirt containing part 31, and thus does not hinder the falling of the dirt water. Moreover, the connection position of the dirt receiving part 32 and the dirt containing part 31 does not have a cleaning dead angle, so as to facilitate the cleaning of the dirt discharge groove 3 and ensure that the dirt discharge groove 3 can be cleaned thoroughly.

[0166] Specifically, as shown in FIG. 9, in one embodiment of the present disclosure, the dirt containing part 31 includes a first part 311 located at the top and a second part 312 located at the bottom, the first part 311 is configured to be in butt joint with the second part 312; the size of the first part 311 is configured to be in a diverging structure with the cross-sectional area increasing from top to bottom; the dirt containing part 32 is configured to be in transition connection with the first part 311, and the size of the second part 312 is configured to be in a converging structure with the cross-sectional area decreasing from top to bottom. Wherein, the first part 311 of the dirt containing part 31 is in a diverging structure with the cross-sectional area increasing from top to bottom, which can facilitate the formation of a variable diameter part with the size increasing from top to bottom, thereby temporarily storing dirt during the discharge of the cleaning device 90, and the cross-sectional area of the dirt containing part 31 gradually increases from top to bottom, and the dirt containing part 32 is butt jointed on both sides of the first part 311, so that the containing area at the bottom is further expanded, thereby facilitating the expansion of the blockage capacity; and the second part 312 gradually decreases in cross-sectional area from top to bottom to butt joint with the drain pipe 6, thereby facilitating the dirt containing part 31 to guide the dirt discharged by the cleaning device 90 into the drain pipe 6, and ensuring that all the dirt can be discharged into the drain pipe 6 after the cleaning device 90 completes the discharge, thereby avoiding the residual of dirt in the dirt containing part 31. In addition, the first part 311 is in a diverging structure with the cross-sectional area gradually increasing from top to bottom, and the second part 312 is in a converging structure with the cross-sectional area gradually decreasing from top to bottom, which is conducive to the flow of washing water flowing down the inner wall of the drain groove from the top of the drain groove. Further, the first part 311 is in a continuous and smooth diverging structure with the cross-sectional area gradually increasing from top to bottom, and the second part 312 is in a continuous and smooth converging structure with the cross-sectional area gradually decreasing from top to bottom. First, the continuous and smooth structure is conducive to the flow of washing water, and second, under the condition of facilitating washing, the continuous and smooth structure further ensures that the distance between the first side wall 323 and the second side wall 324 of the dirt containing part 32 butt jointed on both sides of the first part 311 is maximized, that is, the area surrounded by the dirt containing part 32 is maximized, the volume surrounded by the dirt containing part 32 and the dirt containing part 31 is maximized, the blockage capacity is improved, and the occupied volume of the drain groove is reduced. Specifically, as shown in FIG. 9, in one embodiment of the present disclosure, the dirt containing part 32 is formed on the first part 311 of the dirt containing part 31, and includes a surrounding wall 322 away from one side of the dirt containing part 31, which is configured to extend obliquely downward from the top of the dirt containing part 32 to the transition connection with the bottom of the first part 311. In this way, the sewage discharged by the cleaning device 90 can flow directly to the bottom of the first part 311, that is, the position where the first part 311 and the second part 312 are butt jointed, which is the part with the largest inner diameter of the dirt containing part 31, thereby effectively reducing the impact and splashing of the dirt on the inner wall of the dirt containing part 31, avoiding the formation of vortex in the dirt containing part 31, reducing the residence time of the dirt in the dirt containing part 31, and improving the drainage efficiency of the drain groove 3 of the present disclosure.

[0167] Further, in one embodiment of the present disclosure, the inclined angle of the enclosing wall 322 relative to the horizontal plane is configured to be smaller than the inclined angle of the portion of the second portion 312 located below the enclosing wall 322. That is, as shown in FIG. 10, the sidewall of the second portion 312 corresponding to the position deviates downward from the path in which the enclosing wall 322 extends downward, and when the sewage discharged by the cleaning device 90 flows downward along the enclosing wall 322 to the second portion 312, most of the sewage will not continue to flow downward along the sidewall of the second portion 312, but will flow into the middle part of the inner cavity of the sewage container 31, so as to avoid vortex or splashing of the sewage when the sewage flows to the second portion 312, reduce the impact between the sewage, and ensure the smooth flow of the sewage, thereby effectively improving the discharge speed of the sewage from the bottom of the sewage container 31.

[0168] It can be understood that the inclined angle of the enclosing wall 322 relative to the horizontal plane is smaller than the inclined angle of the portion of the second portion 312 located below the enclosing wall 322 refers to that the inclined angle of any point of the enclosing wall 322 relative to the horizontal plane is smaller than the inclined angle of any point of the portion of the second portion 312 located below the enclosing wall 322.

[0169] As shown in FIG. 9, in one embodiment of the present disclosure, the sewage receiving port 321 is configured to extend beyond the second portion 312 from the position connected with the first portion 311 to the direction of the tray 2. Since the sewage receiving port 321 extends beyond the second portion 312 from the position connected with the first portion 311 to the direction of the tray 2, the sewage receiving port 321 can be conveniently connected with the cleaning device 90, so as to increase the area of the sewage receiving port 321 in the limited space, and facilitate the connection between the sewage discharge port 93 of the cleaning device 90 and the sewage receiving port 321.

[0170] As shown in FIG. 9, in one embodiment of the present disclosure, the size of the first portion 311 in the height direction is greater than the size of the second portion 312 in the height direction.

[0171] It can be understood that, since the dirt receiving portion 31 has the first portion 311 on which the dirt receiving portion 32 is formed, the dirt receiving portion 32 is used to guide the dirty water in the dirty water tank of the cleaning device to the dirt outlet, and the first portion 311 temporarily stores the dirt during the process of the cleaning device 90 discharging the dirt, the main role of the second portion 312 is to guide the dirt discharged by the cleaning device 90 into the dirt discharge pipeline 6 while temporarily storing the dirt together with the dirt receiving portion 32 when the dirt discharge groove is blocked; when the size of the first portion 311 in the height direction is greater than the size of the second portion 312 in the height direction, it is beneficial for the dirt receiving portion 32 to guide the dirt to the position closest to the bottom as much as possible, and at the same time, it can effectively ensure that the volume of the first portion 311 can meet the requirements, prevent the dirty water from overflowing from the dirt discharge groove 3 when the cleaning device 90 discharges the dirt too fast or the dirt discharge pipeline 6 is blocked, and the second portion 312 forms a relatively short and fat area, which is beneficial for guiding the dirt to be quickly discharged from the dirt receiving portion 31, reducing the overall height of the dirt receiving portion 31, and at the same time, when flushing the dirt discharge groove, the height of the first portion 311 is greater, and the slope of the arc surface of the first portion 311 is greater, which is beneficial for the cleaning water flowing out of the top of the first portion 311 to flow downward along the inner wall of the arc surface of the first portion 311. In addition, since the base station has a part of the transverse dirt discharge pipeline in addition to the dirt discharge groove, the dirt discharge pipeline has a capacity, therefore, the size of the second portion in the height direction can be appropriately reduced to reduce the overall height without affecting the capacity below the detection position 81 described below.

[0172] As shown in FIG. 10, OJ is a vertical line passing through point B, OEF is a horizontal line passing through two points E and F on the upper surface of the bottom outlet of the dirt discharge groove 3, AJ is a horizontal line passing through point A, ABK is a straight line passing through two points A and B, K is the intersection of the extension line of AB and the line OEF, h1 is the vertical height from point A to point B, and h2 is the height from point B to point E, that is, the vertical height of the second portion 312.

[0173] In the design of the drain groove, the pollution-accepting opening of the pollution-accepting part needs to be connected with the body of the cleaning device, and A point is the point on the pollution-accepting opening 321 farthest from the front wall surface 11 of the base 1, which is determined. The plane on which the bottom outlet of the drain groove 3 is located is also basically determined, which is approximately the plane on which the upper surface of the tray is located (because the base is located in the space below the upper surface of the tray to accommodate the drain pipeline 6) or the plane on which the charging contact is located (to set the contraction part 34). Therefore, the vertical height |OJ| of A point to E point is also determined, which is the vertical height of A point to the bottom outlet of the drain groove 3, denoted as S2, and h1+h2=|OJ|=S2. B point is the intersection point of the pollution-accepting part extending outward from the base at a certain angle (i.e., the acute angle formed by the AB line and the vertical line OJ, which is approximately the drain angle θ for the convenience of calculation and description) to the base and the vertical outer surface of the base, that is, the vertical line OJ is determined, which is basically the front vertical surface of the base, and B point is basically a point on or near the front vertical surface of the base. According to the different drain angles, B point can move up and down in the direction of the vertical line OJ. Therefore, the length |AJ| of AJ is basically determined, which is the horizontal distance of A point to the front wall surface 11 of the base or its vicinity, denoted as S1, and |AJ|=S1. According to FIG. 10, tan θ = |AJ| / h1 = |OK| / h2, that is, h1 / h2 = |AJ| / |OK|. As described above, it is necessary to ensure that the drain angle θ is within 40°, and then h1 ≥ |AJ| / tan θ, which is the minimum value of h1, that is, the minimum value of h1 / h2. In addition, the extension line of AB is preferably located between the two points of EF, and when |OK|=|OE|, h1 is the maximum value, and h1 / h2 is also the maximum value, at this time, h1 / h2 ≤ |AJ| / |OE|. Since the horizontal distance of A point to F point is generally not less than the vertical height of A point to F point, when the extension line of AB passes through F point, it does not meet the requirement that the drain angle is within 40°. Therefore, the minimum value of h1 is subject to the requirement of the drain angle. That is, (|AJ| / tan θ) / (S2-S1 / tan θ) ≤ h1 / h2 ≤ S1 / S3. |OE| is the horizontal distance of the point (O) of the outlet of the drain groove 3 close to the front wall surface 11 of the base 1 to the front wall surface 11 of the base 1 or its vicinity, denoted as S3. That is, (S1 / tan θ) / (S2-S1 / tan θ) ≤ h1 / h2 ≤ S1 / S3.

[0174] In addition, in order to prevent the dirt in the drain groove 3 from accumulating and not being able to be drained away when the cleaning device 90 is draining, the length of the outlet |EF| of the drain groove 3 is set to be not less than the length of |AJ|, and at the same time, in order to miniaturize the base station, the length of the outlet |EF| of the drain groove 3 also does not need to be too large, and optimally, |EF| ≈ |AJ|.

[0175] In the present example, according to the general size of the cleaning device 90 in the art, |OJ| ≈ 2.3|AJ|.

[0176] In the present example, since the angle of discharge needs to be ensured within 40° to prevent splashing when the dirt falls, when the angle of discharge is exactly equal to 40°, the B point is located at the highest position allowed, 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.

[0177] As described above, the extension line of AB is optimally between the two points of EF, so that the dirt guided through the AB section directly falls within the range of the bottom outlet EF of the dirt groove 3, under this condition, the B point can be located between the intersection of the AE line and the OJ line and the intersection of the AF line and the OJ line. In theory, the outlet E point of the dirt groove 3 can be infinitely close to the front surface of the base, but |EF| is determined, the outlet of the dirt groove 3 needs to communicate with the pipeline opening of the dirt pipeline 6, the outlet of the dirt groove 3 is generally located at the central position of the base, and the base needs to accommodate various other components, in the present embodiment, the distance |OE| between the E point and the OJ vertical line (the front surface of the base) is approximately 0.5|AJ|. When the extension line of AB passes through the E point, h1 / h2=2, the angle of discharge is 33°; when the extension line of AB passes through the F point, h1 / h2=0.7, at this time the angle of discharge is 42°, which does not meet the requirement that the angle of discharge is less than 40°. Therefore, in consideration of the above, the optimal range of h1 / h2 is 1.1-2.

[0178] In addition, considering the smoothness of the sewage, the flushing of the sewage tank, and the maximization of the volume of the sewage tank, the point B is also provided as the maximum transverse diameter of the sewage tank, that is, the boundary between the first part 311 and the second part 312. The maximum transverse diameter of the sewage tank is directly related to the thickness of the base station. The greater the thickness of the base station, the greater the maximum transverse diameter of the sewage tank can be. It can be envisaged that, in order to ensure the smoothness of the sewage and the flushing of the sewage tank, there should only be a smooth arc from the point B to the outlet E of the sewage tank. On this basis, if the maximum transverse diameter of the sewage tank is above the point B, it is assumed that the entire sewage tank in FIG. 10 is moved upward. The dirt falling through the AB section is likely to fall to the BE section and then be discharged, rather than directly falling between the outlet EF. If the maximum transverse diameter of the sewage tank is below the point B, the cross-sectional area of the cavity formed by the sewage-accepting part and the first part 311 above the point B will decrease, resulting in a decrease in the volume of the cavity. In order to ensure that there is only a smooth arc in the BE section, the original arc of the sewage tank needs to be inwardly retracted to the BE arc, and the overall volume will also decrease. Therefore, in summary, the point B is the maximum transverse diameter of the sewage tank, that is, the intersection of the sewage-accepting part and the sewage tank is the maximum transverse diameter of the sewage tank, and is the boundary between the first part 311 and the second part 312. In the above analysis, in order to prevent the dirt from splashing out when it falls onto the sewage surface, the sewage angle is within 40°, h1 is greater than h2, and the top of the first part 311 is higher than the point A, that is, the size of the first part 311 in the vertical direction is greater than h1. Therefore, in order to prevent the dirt from splashing, the size of the first part 311 in the vertical direction is greater than the size of the second part 312 in the vertical direction.

[0179] As shown in FIGS. 6-10, in one embodiment of the present disclosure, the size of the second part 312 in the first direction is greater than the size thereof in the second direction. That is, the thickness of the sewage tank 31 of the present disclosure in the front-rear direction is less than the width thereof in the left-right direction. Since the tray of the base station needs to accommodate the floor brush of the cleaning device, that is, the base station has a size in the axial direction of the rolling brush groove 21 that is at least greater than or equal to the axial length of the rolling brush groove 21, the design of the sewage tank 31 can make full use of the space of the base station in the axial direction of the rolling brush groove 21. Under the premise of ensuring the volume of the sewage tank 31 of the present disclosure, the thickness of the sewage tank 31 and the base station 1 is effectively reduced, which is conducive to the miniaturization of the base station, increases the acceptance and favorability of users, and thus facilitates the arrangement of the cleaning base station 10 of the present disclosure.

[0180] The sewage outlet of the existing cleaning base station is usually arranged on the back surface of the base station, and an external transverse extension pipeline is connected to the sewage outlet to reach the drain. In this way, the dirt discharged from the sewage tank flows through a turning to the sewage outlet of the base station, and then flows into the external extension pipeline through a turning at the sewage outlet of the base station. The dirt passes through two 90° turnings, which greatly consumes the kinetic energy of the dirt, and makes the sewage not smooth enough.

[0181] As shown in FIG. 5, in one embodiment of the present disclosure, the drain pipe 6 is configured to communicate with the bottom of the drain groove 3; the drain pipe 6 at least has a drain section 62 extending in the transverse direction, and a connecting section 61 connecting the drain section 62 with the bottom of the drain groove 3, one end of the connecting section 61 is configured to extend to the bottom of the drain groove 3 in the direction of the bottom of the drain groove 3, and the other end is configured to extend to the drain section 62 in the direction of the drain section 62, and the drain section 62 extends in the first direction.

[0182] In the working process of the cleaning base station 10 of the present disclosure, the brush assembly 94 of the cleaning device 90 is placed on the tray 2, the drain outlet 93 of the cleaning device 90 discharges the dirt into the drain groove 3 in the base 1, and the dirt flows into the connecting section 61 of the drain pipe 6 from the bottom of the drain groove 3, and then flows along the drain section 62, since the drain section 62 extends in 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 length of the cleaning base station 10 of the present disclosure in the second direction.

[0183] In addition, since the drain section 62 extends in the first direction, the dirt only needs to experience one turn of the connecting section 61 in the process of flowing to the drain section 62, the extension direction of the external extension pipe connected to the drain outlet of the base station is consistent with the drain section 62, thereby effectively reducing the kinetic energy loss of the dirt in the process of draining, and the draining is more smooth.

[0184] It can be understood that the transversely extending drain section 62 can extend in the horizontal direction, can not be completely parallel to the horizontal plane, or can be gradually inclined downward, that is, both inclined downward and horizontally.

[0185] As shown in FIG. 1, FIG. 5 and FIG. 6, in one embodiment of the present disclosure, the drain section 62 has a drain outlet 620, the drain outlet 620 is located on the side of the base 1, and the side of the base 1 is the face of the base 1 in the first direction, so that the drain outlet 620 of the drain section 62 can be formed on the side of the base 1, that is, the face of the base 1 in the first direction, and the drain outlet 620 is used to communicate with the sewer pipe 64, so that the cleaning base station 10 of the present disclosure is convenient to connect with the sewer pipe 64 from the side, the overall pipeline installation is convenient, and the occupied volume of the cleaning base station 10 of the present disclosure is also reduced. In addition, since the drain outlet 620 is located on the side of the base 1, and the side of the base 1 is the face of the base 1 in the first direction, the extension direction of the external extension pipe connected to the drain outlet 620 of the base station is consistent with the drain section 62, thereby effectively reducing the kinetic energy loss of the dirt in the process of draining, and the draining is more smooth.

[0186] As shown in FIG. 3, in one embodiment of the present disclosure, the cleaning base station 10 further comprises a contraction section 34, the second section 312 is in communication with the contraction section 34, the contraction section 34 is in communication with the drain pipe 6, the drain pipe 6 forms a drain opening to the sewer on the side of the cleaning base station 10, and the contraction section 34 has a tapered structure with a gradually decreasing cross-sectional area from top to bottom, and the slope of the inner wall surface of the contraction section 34 is greater than the slope of the inner wall surface of the second section 312.

[0187] That is, the drain pipe 6 is connected to the bottom outlet of the drain tank 3 through the contraction section 34, the area of the bottom outlet of the drain tank 3 is greater than the area of the pipe opening of the drain pipe 6, the contraction section 34 is vertically arranged in the base station, and the cross-sectional area gradually decreases from top to bottom to connect the bottom outlet of the drain tank 3 to the drain pipe 6 with 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 section 312, so that the dirt falling from the bottom outlet of the drain tank 3 can directly fall into the pipe opening of the drain pipe 6, thereby maximizing the reduction of the probability of dirt falling on the wall surface of the contraction section 34 and reducing the potential energy loss. The contraction section 34 makes the dirt pass through two different arc surfaces from point B to the pipe opening of the drain pipe 6, gradually contracts, rather than directly and smoothly contracts from point B to the pipe opening of the drain pipe 6, increases the volume of the lower part, is beneficial to reduce the thickness of the base station, and the slope of the two arc surfaces gradually increases, which is beneficial to the dirt directly falling into the pipe opening of the drain pipe 6, increases the smoothness of the drain, and avoids the potential energy loss caused by the collision of the dirt with the arc surface.

[0188] As shown in FIG. 5, the cleaning base station of the present disclosure further comprises a drain assisting device 70, and the output port 701 of the drain assisting device 70 is arranged 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.

[0189] In order to avoid the solid dirt in the dirt from depositing in the drain section 62 and causing the drain pipe 6 to be blocked, the drain assisting device 70 can provide a pressure source to at least the area of the connecting section 61 through the output port 701, thereby increasing the flow speed of the dirt in the drain section 62 of the drain pipe 6, preventing the solid dirt in the dirt from depositing in the drain section 62 and causing the drain pipe 6 to be blocked, not only ensuring that the cleaning base station 10 of the present disclosure can normally drain the dirt in the cleaning equipment 90 to the sewer and the like outside, but also preventing the drain pipe 6 from being blocked, avoiding the user from manually cleaning the blocked drain pipe 6, effectively reducing the user's use burden, and improving the user's use experience.

[0190] In one embodiment of the present disclosure, the pollution discharge assisting device 70 is configured to provide a positive pressure source to the area of the connecting section 61. That is, when the pollution discharge assisting device 70 provides a positive pressure source to the area of the connecting section 61, the pollution discharge assisting device 70 can push the dirt to accelerate the flow of the dirt in the connecting section 61 of the pollution discharge pipeline 6, so as to accelerate the flow of the dirt in the pollution discharge section 62 of the pollution discharge pipeline 6 as soon as possible and then discharge the dirt to the outside. It can be understood that when the pollution discharge assisting device 70 provides a positive pressure source to the area of the connecting section 61, the pollution discharge assisting device 70 can be arranged in the connecting section 61, or can be located at the rear side of the connecting section 61 in the flow direction of the dirt, such as in the pollution discharge groove 3 or the like.

[0191] In another embodiment of the present disclosure, the pollution discharge assisting device 70 is configured to provide a negative pressure source to the area of the connecting section 61. The suction force formed by the negative pressure can accelerate the flow of the dirt in the connecting section 61 of the pollution discharge pipeline 6, and can also accelerate the flow of the dirt in the pollution discharge section 62 of the pollution discharge pipeline 6 as soon as possible and then discharge the dirt to the outside. It can be understood that when the pollution discharge assisting device 70 provides a negative pressure source to the area of the connecting section 61, the pollution discharge assisting device 70 can be arranged in the connecting section 61, or can be located at the front side of the connecting section 61 in the flow direction of the dirt, such as in the pollution discharge section 62 or at the outlet of the pollution discharge section 62 or the like.

[0192] Specifically, as shown in FIG. 5, in one embodiment of the present disclosure, the output port 701 of the pollution discharge assisting device 70 is configured to be located on the side of the connecting section 61 opposite to the pollution discharge section 62, and the pressure source provided by the pollution discharge assisting device 70 is configured to be output in the direction from the connecting section 61 to the pollution discharge section 62 through the output port 701. In this way, during the working process of the pollution discharge assisting device 70, the pressure provided by the pollution discharge assisting device 70 can be output in the direction from the connecting section 61 to the pollution discharge section 62 through the output port 701, so as to promote the movement of the dirt from the connecting section 61 to the side of the pollution discharge section 62, thereby accelerating the flow of the dirt in the pollution discharge pipeline 6.

[0193] As shown in FIG. 5, in one embodiment of the present disclosure, the central axis of the output port 701 is configured to be parallel to the central axis of the pollution discharge section 62. Since the central axis of the output port 701 is parallel to the central axis of the pollution discharge section 62, the pollution discharge assisting device 70 can output the pressure in the extension direction of the pollution discharge section 62, so as to avoid the rotation of the dirt in the pollution discharge section 62 as much as possible during the process of pushing and accelerating the flow of the dirt in the pollution discharge pipeline 6, thereby enabling the dirt to be discharged from the pollution discharge section 62 as soon as possible.

[0194] Further, in one embodiment of the present disclosure, the connecting section 61 is configured to be arc-shaped; and the front projection of the output port 701 of the pollution discharge assisting device 70 in the first direction is configured to at least partially overlap with the front projection of the inner cavity of the pollution discharge section 62 in the first direction.

[0195] Since the connecting section 61 is configured in an arc shape, the dirt flowing downward into the connecting section 61 under the action of gravity can flow along the inner cavity of the connecting section 61 into the dirt discharging section 62. Since the orthographic projection of the output port 701 of the dirt discharging assisting device 70 in the extension direction of the dirt discharging section 62 is configured to at least partially overlap the orthographic projection of the inner cavity of the dirt discharging section 62 in the extension direction thereof, it can be ensured that the pressure source output by the dirt discharging assisting device 70 can directly act on the dirt in the inner cavity of the dirt discharging section 62, thereby effectively improving the utilization efficiency of the pressure source output by the dirt discharging assisting device 70 and accelerating the flow process of the dirt as much as possible.

[0196] Specifically, as shown in FIG. 5, in an embodiment of the present disclosure, the dirt discharging assisting device 70 is a jet assembly 7, which includes a jet member 72 having a jet outlet 71, the jet member 72 being configured to flow out pressurized fluid through the jet outlet 71; the opening direction of the jet outlet 71 is configured to face the first direction, and the fluid flowing out of the jet outlet 71 flows along the first direction. That is, in the working process of the jet assembly 7, the jet member 72 of the jet assembly 7 can flow out pressurized fluid in the first direction from the jet outlet 71, and the pressurized fluid can flow along the first direction to push the dirt to accelerate the flow in the connecting section 61 of the dirt discharging pipeline 6 and then accelerate the flow in the dirt discharging section 62 of the dirt discharging pipeline 6 as soon as possible and be discharged to the outside.

[0197] It can be understood that if a jet member is added to the existing cleaning base station to assist in dirt discharging, since the jet member faces the dirt discharging port on the back of the base station, the distance from the jet member to the dirt discharging outlet is short, and the water flow sprayed by the jet member is blocked by the curved part of the dirt discharging port of the base station, it is difficult to play a role in assisting dirt discharging. However, in the cleaning base station of the present disclosure, since the jet member 72 of the jet assembly 7 can flow out pressurized fluid in the first direction from the jet outlet 71, the pressurized fluid can be sprayed without being blocked, the assisting path of the pressurized fluid is prolonged, and the role of assisting dirt discharging is maximized.

[0198] It can be understood that, as shown in FIG. 5, the pressurized fluid can be pressurized liquid, which can flow into the dirt in the connecting section 61 after flowing into the jet inlet, and push the dirt to flow along the dirt discharging section 62 to the outlet direction of the dirt discharging section 62 under the action of its own kinetic energy. In another embodiment of the present disclosure, the pressure source can also be pressurized gas, which can also push the dirt to flow along the dirt discharging section 62 to the outlet direction of the dirt discharging section 62 under the action of its own gas pressure. The principle is similar and will not be described here.

[0199] Specifically, as shown in FIG. 5, in one embodiment of the present disclosure, a pipe joint 630 is arranged on the side of the connection section 61 opposite to the blowdown section 62; the jet element 72 is configured to be installed in the pipe joint 630, and the jet outlet 71 is configured to face the direction of the connection section 61 and the blowdown section 62. That is, during the processing of the connection section 61, the pipe joint 630 needs to be processed on the side of the connection section 61 opposite to the blowdown section 62; when the jet element 72 is installed, the jet element 72 is installed in the pipe joint 630, and the jet outlet 71 faces the direction of the connection section 61 and the blowdown section 62, so that after the pressurized fluid flows out of the jet outlet 71, it can flow along the pipe joint 630 to the side of the blowdown section 62, thereby pushing the dirt to flow along the blowdown section 62 to the outlet direction of the blowdown section 62.

[0200] Further, as shown in FIG. 5, in one embodiment of the present disclosure, the pipe joint 630 is a sleeve 63, and the jet element 72 is configured to be installed in the sleeve 63; the bottom of the sleeve 63 is configured to be higher than the bottom of the blowdown section 62, and the top of the sleeve 63 is configured to be lower than the top of the blowdown section 62.

[0201] Since the bottom of the sleeve 63 is higher than the bottom of the blowdown section 62, and the top of the sleeve 63 is lower than the top of the blowdown section 62, after the jet element 72 is installed in the sleeve 63, the bottom of the jet outlet 71 is higher than the bottom of the blowdown section 62, and the top of the jet outlet 71 is lower than the top of the blowdown section 62, so that after the pressurized fluid flows out of the sleeve 63, it can directly impact on the dirt in the blowdown pipeline 6 and push the dirt to flow along the rear section of the connection section 61 to the blowdown section 62; the pressurized fluid will not impact on the inner wall of the connection section 61 or other positions, thereby effectively avoiding the waste of kinetic energy of the pressurized fluid, improving the effect of the jet assembly 7 in pushing the dirt to flow, and preventing the dirt from blocking the blowdown pipeline 6.

[0202] Further, as shown in FIG. 5, in one embodiment of the present disclosure, the sleeve 63 is configured to extend from the inner wall of the connection section 61 to the direction away from the blowdown section 62, and the opening of the sleeve 63 on the inner wall of the connection section 61 is configured to be adapted to the shape of the inner wall of the connection section 61. Since the sleeve 63 extends from the inner wall of the connection section 61 to the direction away from the blowdown section 62, and the opening of the sleeve 63 on the inner wall of the connection section 61 is adapted to the shape of the inner wall of the connection section 61, the sleeve 63 will not extend into the connection section 61, and the dirt flowing along the connection section 61 will not be hindered by the sleeve 63, thereby ensuring that the dirt can smoothly flow along the connection section 61 and be accelerated to flow to the blowdown section 62 under the pushing action of the pressurized fluid when passing through the opening of the sleeve 63.

[0203] As shown in FIG. 5, in one embodiment of the present disclosure, a fluid pipe is arranged on the base 1 and communicates with the jetting member 72, and the fluid is configured to flow into the jetting member 72 through the fluid pipe under the action of the power source device. In this way, during the operation of the jetting assembly 7, the fluid can be pressurized under the action of the power source device and then flow into the jetting member 72 through the fluid pipe, and then flow out from the jetting outlet 71 of the jetting member 72. It can be understood that the fluid can be tap water or cleaning liquid, which can come from an external water source such as a tap, or from a water tank or a cleaning liquid tank inside the base station, and the power source device can be a water pump or the like, which is not limited here.

[0204] In another embodiment of the present disclosure, a fluid pipe is arranged on the base 1 and communicates with the jetting member 72, and the fluid pipe is configured to be connected to a tap, and the fluid in the tap is configured to flow into the jetting member 72 through the fluid pipe under the action of the water pressure of the tap itself. It can be understood that since the tap has its own water pressure, when the fluid pipe is connected to the tap, the fluid in the tap can flow into the jetting member 72 through the fluid pipe under the action of the water pressure of the tap itself, and then flow out from the jetting outlet 71 of the jetting member 72.

[0205] As shown in FIG. 5, in one embodiment of the present disclosure, the jetting member 72 includes a jetting pipe 721, and the jetting outlet 71 is arranged on the end face of the jetting pipe 721; the jetting member 72 further includes a Venturi tube 722 located in the jetting pipe 721, and the fluid is configured to flow out from the jetting outlet 71 after passing through the Venturi tube 722.

[0206] That is, during the operation of the jetting assembly 7, when the pressurized fluid of the jetting assembly 7 flows into the jetting pipe 721 of the jetting member 72, it will flow through the Venturi tube 722 in the jetting pipe 721, and then flow out from the jetting outlet 71. The pressurized fluid flowing through the Venturi tube 722 can have a high flow rate and good stability. In the case where the total flow area of the jetting outlet 71 is smaller than the area of the minimum flow cross section of the Venturi tube 722, the sewage jetting can obtain a greater flow rate, thereby improving the acceleration efficiency of the pressurized fluid on the dirt.

[0207] As shown in FIG. 5, in one embodiment of the present disclosure, the jetting member 72 is configured to be located on the side of the connecting section 61 opposite to the sewage section 62, and the opening direction of the jetting outlet 71 is configured to be directed to the extension direction of the sewage section 62; the jetting outlet 71 at least partially overlaps with the inner cavity of the sewage section 62 in the height direction.

[0208] Since the jet flow piece 72 is located on the side of the connecting section 61 opposite to the dirt discharging section 62, and the opening direction of the jet flow outlet 71 is towards the extending direction of the dirt discharging section 62, the jet flow outlet 71 at least partially overlaps the inner cavity of the dirt discharging section 62 in the height direction, which can ensure that the pressurized fluid output by the jet flow assembly 7 can flow along the extending direction of the dirt discharging section 62 after flowing out of the jet flow outlet 71, so as to impact the dirt in the connecting section 61 and directly push the dirt to flow along the rear section of the connecting section 61 to the dirt discharging 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.

[0209] As shown in FIG. 5, in one embodiment of the present disclosure, the central axis of the jet flow outlet 71 is configured to be parallel to the central axis of the dirt discharging section 62. Since the central axis of the jet flow outlet 71 is parallel to the central axis of the dirt discharging section 62, the pressurized fluid flowing out of the jet flow outlet 71 can flow along the central axis of the dirt discharging section 62, which can avoid the dirt rotating in the dirt discharging section 62 as much as possible during the process of the pressurized fluid pushing the dirt to flow in the dirt discharging pipeline 6, so that the dirt can be discharged from the dirt discharging section 62 as soon as possible.

[0210] It can be understood that the central axis of the jet flow outlet 71 refers to the axis obtained by the central point between the highest point and the lowest point of the jet flow outlet 71 along the extending direction of the jet flow outlet 71, and the jet flow outlet 71 can be symmetrically arranged up and down as a whole or asymmetrically arranged, which is not limited herein.

[0211] Further, as shown in FIG. 5, in one embodiment of the present disclosure, the central axis of the jet flow outlet 71 is configured to be higher than the central axis of the dirt discharging section 62. It can be understood that the pressurized fluid will fall a certain distance during the process of flowing into the dirt discharging pipeline 6 from the jet flow outlet 71, i.e., the central position of the pressurized fluid entering the dirt discharging pipeline 6 is lower than the central position of the jet flow outlet 71.

[0212] Therefore, in the case that the central axis of the jet flow outlet 71 is higher than the central axis of the dirt discharging section 62, the central position of the pressurized fluid entering the dirt discharging pipeline 6 can be located near the central axis of the dirt discharging section 62, so as to ensure that the pressurized fluid can impact the dirt in the central position of the dirt discharging section 62, avoid the dirt rotating along the axial direction of the dirt discharging pipeline 6 during the process of flowing along the dirt discharging pipeline 6 under the action of the pressurized fluid and being retained in the dirt discharging pipeline 6, thereby accelerating the flow speed of the dirt along the dirt discharging pipeline 6 and facilitating the dirt to be discharged from the dirt discharging pipeline.

[0213] ​​​​​As shown in FIG. 5, in one embodiment of the present disclosure, the top end of the jet outlet 71 is configured to be lower than the top end of the inner cavity of the drain section 62. Since the top end of the jet outlet 71 is lower than the top end of the inner cavity of the drain section 62, the fluid located at the upper part of the jet outlet 71 can directly impact on the dirt in the drain pipe 6 and push the dirt to move along the rear section of the connecting section 61 to the inner cavity of the drain section 62 after the pressurized fluid flows out of the jet outlet 71, without impacting the dirt to the position on the connecting section 61 which is higher than the top end of the inner cavity of the drain section 62, effectively avoiding the waste of kinetic energy of the pressurized fluid, thereby improving the effect of the jet assembly 7 in pushing the dirt to flow and preventing the dirt from blocking the drain pipe 6.

[0214] Similarly, as shown in FIG. 5, in one embodiment of the present disclosure, the bottom end of the jet outlet 71 is configured to be higher than the bottom end of the inner cavity of the 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, the fluid located at the lower part of the jet outlet 71 can directly impact on the dirt in the drain pipe 6 and push the dirt to move along the rear section of the connecting section 61 to the inner cavity of the drain section 62 after the pressurized fluid flows out of the jet outlet 71, without impacting the dirt to the position on the connecting section 61 which is lower than the bottom end of the inner cavity of the drain section 62, also effectively avoiding the waste of kinetic energy of the pressurized fluid, thereby improving the effect of the jet assembly 7 in pushing the dirt to flow and preventing the dirt from blocking the drain pipe 6.

[0215] As shown in FIG. 13 and FIG. 14, in one embodiment of the present disclosure, the jet outlet 71 is provided in plurality, and the plurality of jet outlets 71 are configured to be uniformly arranged on the end face of the jet member 72. Since the jet outlet 71 is provided in plurality and the plurality of jet outlets 71 are uniformly arranged on the end face of the jet member 72, the pressurized fluid flowing out of each jet outlet 71 can collectively push the dirt, so that the force receiving surface of the dirt in the drain pipe 6 is larger and the force is more balanced, which can make the dirt at all circumferential positions be able to receive the thrust from the pressurized fluid to flow to the outlet of the drain pipe 6, avoiding the situation that only part of the dirt accelerates to flow and part of the dirt does not accelerate to flow, resulting in the solid dirt in the dirt depositing in the drain pipe 6.

[0216] Specifically, as shown in FIG. 13 and FIG. 14, in one embodiment of the present disclosure, the jet flow outlet 71 comprises a center outlet 711 located at the center of the jet flow piece 72 and edge outlets 712 arranged at the edges of the jet flow piece 72, the edge outlets 712 are arranged at least two on at least two sides of the center outlet 711, and each edge outlet 712 is configured to surround the center outlet 711. In this way, the pressurized fluid sprayed from the center outlet 711 can impact the central part of the dirt in the blowdown pipe 6, and the pressurized fluid sprayed from the edge outlet 712 can impact the circumferential edge part of the dirt in the blowdown pipe 6, so as to ensure that the dirt in the center and edge positions of the blowdown pipe 6 can be accelerated by the pressurized fluid, so that the stress of the dirt in the blowdown pipe 6 is more balanced, which is beneficial to the flow of the dirt and avoids the deposition of solid pollutants in the blowdown pipe 6.

[0217] As shown in FIG. 13 and FIG. 14, in one embodiment of the present disclosure, the size of the center outlet 711 is configured to be larger than the size of each edge outlet 712, so that the thrust of the dirt in the central part of the blowdown pipe 6 can be greater than the thrust of the dirt in the edge part, so that the flow speed of the dirt in the central part can be faster than the flow speed of the dirt in the edge part, thereby effectively improving the kinetic energy utilization efficiency of the pressurized fluid and reducing the waste of kinetic energy.

[0218] In another embodiment of the present disclosure, the inner diameter of the center outlet 711 is configured to be equal to the size of each edge outlet 712, so that the thrust of the dirt in the central part of the blowdown pipe 6 is balanced compared with the thrust of the dirt in the edge part, so that the dirt in the blowdown pipe 6 can flow as a whole, avoiding the flow speed of part of the dirt being too slow and preventing the deposition of solid pollutants in the blowdown pipe 6.

[0219] As shown in FIG. 5, in one embodiment of the present disclosure, the center axis of the center outlet 711 is configured to be parallel to the center axis of the blowdown section 62. Since the center axis of the center outlet 711 is parallel to the center axis of the blowdown section 62, the pressurized fluid flowing out of the center outlet 711 can flow along the center axis of the blowdown section 62, which can avoid the rotation of the dirt in the blowdown section 62 during the process of the pressurized fluid pushing the dirt to flow in the blowdown pipe 6, so that the dirt can be discharged from the blowdown section 62 as soon as possible.

[0220] As shown in FIG. 14, in one embodiment of the present disclosure, the cross-sectional shape of the jet flow outlet 71 is configured to be circular. Since the cross-sectional shape of the jet flow outlet 71 is circular, the pressure of the pressurized fluid flowing out of the circular jet flow outlet 71 is balanced, and the flow speed decay is also minimal.

[0221] As shown in FIG. 5, in one embodiment of the present disclosure, the jet flow assembly 7 extends along the first direction. Since the extension direction of the jet flow assembly 7 itself extends along the first direction, it can be ensured that the pressurized fluid has no kinetic energy loss when being ejected along the first direction.

[0222] In order to control the operation of the blowdown assisting device 70 of the present disclosure, the control unit of the present disclosure is configured to control the blowdown assisting device 70 to start during the discharge of the dirty in the blowdown tank 3, or at the same time as starting the discharge of the dirty, or before the discharge of the dirty. In this way, during the discharge of the dirty in the blowdown tank 3, or at the same time as starting the discharge of the dirty, or before the discharge of the dirty, the control unit controls the blowdown assisting device 70 to start, and during the discharge of the dirty by the cleaning device 90, the blowdown assisting device 70 can continuously provide a pressure source to the area of the connecting section 61 through the output port 701, so as to ensure that during the discharge of the dirty by the cleaning device 90, the flow speed of the dirty in the blowdown pipeline 6 can be increased under the action of the blowdown assisting device 70, and the solid pollutants in the dirty can be completely prevented from being deposited in the blowdown section 62, thereby avoiding the blockage of the blowdown pipeline 6.

[0223] In another embodiment of the present disclosure, the control unit of the present disclosure controls the blowdown assisting device 70 to start when the dirty in the blowdown tank 3 reaches a predetermined liquid level. That is, the blowdown assisting device 70 only starts to work in the case that the amount of dirty in the blowdown tank 3 is large, the discharge of the dirty is slow, and the solid pollutants in the dirty are likely to be deposited in the blowdown section 62. In this way, the blowdown assisting device 70 can be started to work before the blockage of the blowdown pipeline 6 is likely to occur, thereby avoiding the blockage of the blowdown pipeline 6. In the case of smooth blowdown, the blowdown assisting device 70 does not need to be driven, thereby effectively saving the work of the blowdown assisting device 70, saving relevant resources and reducing energy waste.

[0224] In one specific embodiment of the present disclosure, the EV2 (electromagnetic valve for controlling the water supply of the jet flow assembly) is opened for 10s. The 10s is calculated according to a 1.5m sewer pipe with an inner diameter of 32mm and a length of 1.5m. The water flow of the jet flow assembly is 8L / min (the minimum flushing flow rate in the laboratory). The water required to push the dirty from the head of the sewer pipe to the tail is approximately the volume of the entire sewer pipe {3.14*(32 / 2)^2*1500} = 1,205,760mm^3. The calculation time (1,205,760 / 8000000*60) = 9.04s. Considering the length of the sewer pipeline, the jet flow assembly is opened for 10s, that is, the single flushing time is 10s, and the opening time is more than 12s.

[0225] The water discharge plate is opened, and the jetting member is opened. If the water discharge plate is not opened for the first time, the jetting member is closed. At this time, the jetting member works for a first time length. Until the water discharge plate is opened for the second time, the jetting member continues to work for a second time length. The first time length + the second time length = 10 s.

[0226] As shown in FIGS. 10-12, in one embodiment of the present disclosure, the cleaning base station 10 comprises a base station self-cleaning assembly 5 located at the sewage tank 3, the base station self-cleaning assembly 5 is configured to be located at a position higher than the end face of the sewage receiving port 321; the base station self-cleaning assembly 5 is configured to output cleaning liquid to the inner cavity of the sewage containing part 31 and / or the sewage receiving part 32.

[0227] In this way, during the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning equipment 90 is discharged from the sewage pipe 6 into the sewage tank 3, the base station self-cleaning assembly 5 can output cleaning liquid to the inner cavity of the sewage containing part 31 and / or the sewage receiving part 32, thereby cleaning the inner wall of the sewage containing part 31 and / or the sewage receiving part 32, preventing dirt from remaining on the inner wall of the sewage containing part 31 and / or the sewage receiving part 32. Moreover, since the sewage tank 3 mainly uses the sewage receiving part 32 to receive the dirt from the cleaning equipment 90, the base station self-cleaning assembly 5 is located at a position higher than the end face of the sewage receiving port 321, the sewage receiving part 32 is lower than the sewage containing part 31, and the base station self-cleaning assembly 5 can fully clean the sewage receiving part 32 when cleaning the sewage tank 3, preventing cleaning dead angles in the sewage tank 3.

[0228] As shown in FIG. 10, in one embodiment of the present disclosure, the base station self-cleaning assembly 5 is located at the top of the sewage tank 3, and the base station self-cleaning assembly 5 is configured to output cleaning liquid to the inner cavity of the sewage containing part 31 from the top of the sewage containing part 31, and to the top of the sewage receiving part 32 and the inner cavity of the sewage receiving part 32 from the top of the sewage containing part 31. In this way, during the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning equipment 90 is discharged from the sewage pipe 6 into the sewage tank 3, the base station self-cleaning assembly 5 can output cleaning liquid to the inner cavity of the sewage containing part 31 from the top of the sewage containing part 31, and to the top of the sewage receiving part 32 and the inner cavity of the sewage receiving part 32 from the top of the sewage containing part 31, thereby cleaning the inner cavity of the sewage containing part 31 and the sewage receiving part 32, preventing dirt from remaining on the inner cavity of the sewage containing part 31 and the sewage receiving part 32, ensuring that the sewage tank 3 of the present disclosure is clean and odorless, thereby effectively improving the user experience.

[0229] Moreover, since the base station self-cleaning assembly 5 can output cleaning liquid to the inner cavity of the sewage containing part 31 and the inner cavity of the sewage receiving part 32 from the top of the sewage containing part 31, it is not necessary to separately provide a cleaning mechanism for the sewage containing part 31 and the sewage receiving part 32, which can effectively simplify the waterway structure of the cleaning base station 10 of the present disclosure, and promote the miniaturization of the cleaning base station 10 of the present disclosure.

[0230] As shown in FIG. 10, FIG. 15, FIG. 16 and FIG. 23, in one embodiment of the present disclosure, the base station self-cleaning assembly 5 comprises a dirt-containing cleaning element 51, a dirt-accepting cleaning element 52 and a liquid inlet pipe 53, the dirt-containing cleaning element 51 is arranged at the top of the inner cavity of the dirt-containing part 31 and is configured to output cleaning liquid to the inner cavity of the dirt-containing part 31, the dirt-accepting cleaning element 52 is arranged at the top of the inner cavity of the dirt-accepting part 32 and is configured to output cleaning liquid to the inner cavity of the dirt-accepting part 32; the liquid inlet pipe 53 is in communication with the dirt-containing cleaning element 51 and the dirt-accepting cleaning element 52, and the cleaning liquid flowing into the liquid inlet pipe 53 is configured to flow partially into the dirt-containing cleaning element 51 and partially to the dirt-accepting cleaning element 52.

[0231] In this way, during the operation of the cleaning base station 10 of the present disclosure, the cleaning liquid flowing into the liquid inlet pipe 53 is configured to flow partially into the dirt-containing cleaning element 51 and partially to the dirt-accepting cleaning element 52, the cleaning liquid flowing into the dirt-containing cleaning element 51 can output cleaning liquid from the top of the inner cavity of the dirt-containing part 31 to the inner cavity of the dirt-containing part 31, thereby cleaning the inner cavity of the dirt-containing part 31, and the cleaning liquid flowing into the dirt-accepting cleaning element 52 can output cleaning liquid from the top of the inner cavity of the dirt-accepting part 32 to the inner cavity of the dirt-accepting part 32, thereby cleaning the inner cavity of the dirt-accepting part 32, so that only one liquid inlet pipe 53 is needed to provide cleaning liquid to the dirt-containing cleaning element 51 and the dirt-accepting cleaning element 52 at the same time, thereby effectively simplifying the waterway structure of the cleaning base station 10 of the present disclosure.

[0232] Specifically, as shown in FIG. 10, in one embodiment of the present disclosure, an outer wall at the top of the dirt-containing part 31 is provided with a liquid inlet cavity 54 in communication with the liquid inlet pipe 53; wherein the dirt-containing cleaning element 51 is configured to be arranged at a position corresponding to the liquid inlet cavity 54 and in communication with the liquid inlet cavity 54; the dirt-accepting cleaning element 52 comprises a liquid discharge section 521 and a liquid inlet section 522, the liquid discharge section 521 is used to output cleaning liquid to the inner cavity of the dirt-accepting part 32; the liquid inlet section 522 is configured to connect the liquid inlet cavity 54 and the liquid discharge section 521.

[0233] That is, during the operation of the cleaning base station 10 of the present disclosure, the cleaning liquid flowing into the liquid inlet pipe 53 will enter the liquid inlet cavity 54, part of the cleaning liquid in the liquid inlet cavity 54 will flow into the dirt-containing cleaning element 51, and the remaining part of the cleaning liquid in the liquid inlet cavity 54 will flow along the liquid inlet section 522 to the liquid discharge section 521, thereby achieving the purpose of simultaneously providing cleaning liquid to the dirt-containing cleaning element 51 and the liquid discharge section 521, and the overall liquid inlet structure is simple and the flow of cleaning liquid is also relatively smooth.

[0234] As shown in FIG. 10, in one embodiment of the present disclosure, a cover plate 55 is arranged on the outer wall of the dirt holding portion 31, the cover plate 55 is buckled on the outer wall of the dirt holding portion 31, and the cover plate 55 and the outer wall of the dirt holding portion 31 form the liquid inlet cavity 54, and the liquid inlet pipe 53 is arranged on the cover plate 55. In this way, the liquid inlet cavity 54 can be formed between the cover plate 55 buckled on the outer wall of the dirt holding portion 31 and the dirt holding portion 31, and the liquid inlet pipe 53 is arranged on the cover plate 55, which can directly communicate with the liquid inlet cavity 54, without the need to arrange other communication pipe fittings, thereby further simplifying the liquid inlet structure.

[0235] Specifically, as shown in FIG. 10, in one embodiment of the present disclosure, the outer wall of the dirt holding portion 31 is provided with a through hole 56 corresponding to the position of the liquid inlet cavity 54, and the liquid inlet cavity 54 is configured to communicate with the dirt holding and cleaning member 51 through the through hole 56. In this way, after the cleaning liquid flows into the liquid inlet cavity 54 from the liquid inlet pipe 53, it can flow to the dirt holding and cleaning member 51 through the through hole 56, i.e. to the top of the inner cavity of the dirt holding portion 31, and then clean the inner cavity of the dirt holding portion 31.

[0236] As shown in FIG. 10, in one embodiment of the present disclosure, the dirt holding portion 31 includes a first portion 311 located above and a second portion 312 located below, and the first portion 311 is configured to be butted against the second portion 312; the size of the first portion 311 is configured to be a gradually expanding structure with the cross-sectional area increasing from top to bottom; and the dirt holding and cleaning member 51 is arranged at the center position of the inner cavity of the first portion 311 of the dirt holding portion 31, and is configured to output cleaning liquid radially to the periphery.

[0237] Since the first portion 311 of the dirt holding portion 31 located above is a gradually expanding structure with the cross-sectional area increasing from top to bottom, and the dirt holding and cleaning member 51 is arranged at the center position of the inner cavity of the first portion 311 of the dirt holding portion 31, when the dirt holding and cleaning member 51 outputs cleaning liquid radially to the periphery, it can clean the entire circumference of the inner cavity of the dirt holding portion 31, avoiding the occurrence of cleaning dead angles in the inner cavity of the dirt holding portion 31.

[0238] As shown in FIG. 9, in one embodiment of the present disclosure, the top of the dirt receiving portion 32 is configured to extend outward from the dirt holding portion 31 to form a dirt receiving port 321 for butting against the dirt outlet 93 of the cleaning equipment 90, and the dirt receiving and cleaning member 52 is configured to at least partially surround the circumferential side wall of the dirt receiving port 321 and is configured to output cleaning liquid from at least part of the circumference of the dirt receiving port 321. In this way, since the dirt receiving and cleaning member 52 at least partially surrounds the circumferential side wall of the dirt receiving port 321 and outputs cleaning liquid from at least part of the circumference of the dirt receiving port 321, the dirt receiving and cleaning member 52 can clean at least part of the circumferential side wall of the dirt receiving portion 32, reduce the residue of dirt on the circumferential side wall of the dirt receiving portion 32, and reduce the odor formed by the residue of dirt in the cleaning base station 10 of the present disclosure.

[0239] Specifically, as shown in FIG. 7, in one embodiment of the present disclosure, the pollution-accepting part 32 comprises a surrounding wall 322 away from the side of the pollution-accepting part 32 connected to the pollution-containing part 31, the surrounding wall 322 is configured to extend downward from the top of the pollution-accepting part 32 to the corresponding position of the pollution-containing part 31; the pollution-accepting part 32 further comprises a first side wall 323 and a second side wall 324 on both sides of the surrounding wall 322, the first side wall 323, the second side wall 324, and the surrounding wall 322 are configured to form the pollution-accepting part 32 on the pollution-containing part 31; the pollution-accepting cleaning element 52 is configured to be located at the top of the first side wall 323, the second side wall 324, and the surrounding wall 322, and is configured to output the cleaning liquid downward from the top of the first side wall 323, the second side wall 324, and the surrounding wall 322.

[0240] In this way, the pollution-accepting cleaning element 52 can output the cleaning liquid downward from the top of the first side wall 323, the second side wall 324, and the surrounding wall 322, so as to ensure that the pollution-accepting cleaning element 52 can clean the first side wall 323, the second side wall 324, and the surrounding wall 322 of the pollution-accepting part 32, avoid the dirt remaining on the first side wall 323, the second side wall 324, and the surrounding wall 322 of the pollution-accepting part 32, and minimize the odor caused by the dirt remaining in the cleaning base station 10 of the present disclosure.

[0241] Further, as shown in FIG. 7, in one embodiment of the present disclosure, the end face where the pollution-accepting port 321 is located is configured to extend horizontally or downwardly from the position connected to the pollution-containing part 31; the pollution-accepting cleaning element 52 is configured to be arranged along the end face of the pollution-accepting port 321. Since the pollution-accepting cleaning element 52 is arranged along the end face of the pollution-accepting port 321, the cleaning liquid output by the pollution-accepting cleaning element 52 can flow downward from the end face of the pollution-accepting port 321, avoiding the occurrence of cleaning dead angles in the pollution-accepting part 32.

[0242] As shown in FIGS. 10-12, in one embodiment of the present disclosure, the pollution-accepting part 32 comprises a pollution-accepting part 32 having a pollution-accepting port 321 configured to be connected to the pollution-accepting port 93 of the cleaning equipment 90; the pollution-accepting cleaning element 52 is arranged around the pollution-accepting port 321 and is configured to output the cleaning liquid to the inner cavity of the pollution-accepting part 32; the pollution-accepting cleaning element 52 comprises a liquid inlet section 522 and a liquid outlet section 521, the liquid outlet section 521 is configured to communicate with the liquid inlet section 522 and is arranged at a position lower than the liquid inlet section 522; the cleaning liquid is configured to flow from the liquid inlet section 522 to the liquid outlet section 521, and is configured to flow from the liquid outlet section 521 to the inner cavity of the pollution-accepting part 32.

[0243] Thus, during the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged from the dirt discharge port 93 of the cleaning device 90 is discharged from the dirt receiving port 321 of the dirt receiving part 32 into the dirt discharge groove 3 and then discharged from the dirt discharge pipeline 6, the dirt receiving cleaning member 52 can output the cleaning liquid to the inner cavity of the dirt receiving part 32 to clean the inner cavity of the dirt receiving part 32. Since the dirt receiving cleaning member 52 is arranged around the dirt receiving port 321, the dirt receiving cleaning member 52 can clean the inner cavity of the dirt receiving part 32 when it outputs the cleaning liquid, preventing the dirt from remaining on the inner cavity of the dirt receiving part 32 and ensuring that the inner cavity of the dirt receiving part 32 of the present disclosure is clean and odor-free, thereby effectively improving the user experience.

[0244] Moreover, since the dirt receiving cleaning member 52 includes the liquid inlet section 522 and the liquid outlet section 521, the liquid outlet section 521 is in communication with the liquid inlet section 522 and is arranged at a position lower than the liquid inlet section 522, so that the cleaning liquid can naturally flow from the liquid inlet section 522 to the liquid outlet section 521 under the action of its own gravity and then to the inner cavity of the dirt receiving part 32 through the liquid outlet section 521, without the need for external power to drive the flow of the cleaning liquid, thereby eliminating the need for a power source for the dirt receiving cleaning member 52, effectively simplifying the waterway structure of the cleaning base station 10 of the present disclosure and promoting the miniaturization of the cleaning base station 10 of the present disclosure.

[0245] Further, as shown in FIG. 12, in an embodiment of the present disclosure, the two ends of the liquid inlet section 522 are in communication with the two ends of the liquid outlet section 521, and the liquid inlet section 522 and the liquid outlet section 521 are configured to form a ring-shaped structure. Since the two ends of the liquid inlet section 522 are in communication with the two ends of the liquid outlet section 521 and the liquid inlet section 522 and the liquid outlet section 521 form a ring-shaped structure, the cleaning liquid entering the liquid inlet section 522 will be divided into two parts and flow to the two ends of the liquid outlet section 521, and then flow along the liquid outlet section 521 until it flows to the middle of the liquid outlet section 521, and during the flow of the cleaning liquid along the liquid outlet section 521, part of it will flow out of the liquid outlet section 521 to the inner cavity of the dirt receiving part 32, thereby cleaning the inner cavity of the dirt receiving part 32. Since the cleaning liquid flows into the liquid outlet section 521 from both ends, not only is the path of the cleaning liquid the shortest and the flow time the shortest, but also the water pressure loss of the cleaning liquid is the least.

[0246] As shown in FIG. 7 and FIG. 12, in one embodiment of the present disclosure, the dirt receiving part 32 comprises an enclosing wall 322 configured to form a dirt discharging surface 325 by extending downwardly from the top of the dirt receiving part 32, and a first side wall 323 and a second side wall 324 located on both sides of the enclosing wall 322, the first side wall 323, the second side wall 324 and the enclosing wall 322 are configured to enclose the dirt receiving part 32; the liquid discharging section 521 is configured to extend along the top of the first side wall 323, the enclosing wall 322 and the second side wall 324, and the cleaning liquid is configured to flow out of the liquid discharging section 521 from the positions corresponding to the first side wall 323, the enclosing wall 322 and the second side wall 324. Since the liquid discharging section 521 extends along the top of the first side wall 323, the enclosing wall 322 and the second side wall 324, the cleaning liquid flows out of the liquid discharging section 521 from the positions corresponding to the first side wall 323, the enclosing wall 322 and the second side wall 324, and after the cleaning liquid flows out of the liquid discharging section 521 from the positions corresponding to the first side wall 323, the enclosing wall 322 and the second side wall 324, the first side wall 323, the enclosing wall 322 and the second side wall 324 can be cleaned, avoiding the dirt remaining on the first side wall 323, the enclosing wall 322 and the second side wall 324 of the dirt receiving part 32, and avoiding the odor caused by the dirt remaining on the dirt receiving part 10 as much as possible.

[0247] As shown in FIG. 9, in one embodiment of the present disclosure, the dirt discharging groove 3 comprises a dirt containing part 31 located in the base 1, and a dirt receiving part 32 disposed on the side wall of the dirt containing part 31 and communicating with the inner cavity of the dirt containing part 31, the top of the dirt receiving part 32 is configured to be lower than the top of the dirt containing part 31; the liquid discharging section 521 is configured to be disposed on the top of the dirt receiving part 32, and the liquid inlet section 522 is configured to be disposed on the dirt containing part 31 adjacent to the dirt receiving part 32. Since the top of the dirt receiving part 32 is lower than the top of the dirt containing part 31, the liquid discharging section 521 is disposed on the top of the dirt receiving part 32, and the liquid inlet section 522 is disposed on the dirt containing part 31 adjacent to the dirt receiving part 32, the cleaning liquid can flow naturally from the position adjacent to the dirt receiving part 32 on the dirt containing part 31 to the liquid discharging section 521 on the top of the dirt receiving part 32 under the action of its own gravity, without the need for external power to provide power for the flow of the cleaning liquid, thereby the power source required by the dirt receiving cleaning member 52 can be saved.

[0248] As shown in FIG. 12, in one embodiment of the present disclosure, the top of the pollution-containing part 31 is provided with a liquid inlet cavity 54, which is configured to communicate with the middle part of the liquid inlet section 522, and the cleaning liquid in the liquid inlet cavity 54 is configured to flow from the middle part of the liquid inlet section 522 to both sides thereof; a flow distribution plate 523 is arranged in the flow path from the liquid inlet cavity 54 to the liquid inlet section 522, and the cleaning liquid in the liquid inlet cavity 54 is configured to flow to both sides of the liquid inlet section 522 through both sides of the flow distribution plate 523, respectively. In this way, the cleaning liquid in the liquid inlet cavity 54 can flow from the middle part of the liquid inlet section 522 to both sides of the liquid inlet section 522 through both sides of the flow distribution plate 523 under the blocking action of the flow distribution plate 523, thereby naturally achieving the purpose of distributing the cleaning liquid to both ends of the liquid inlet section 522.

[0249] As shown in FIG. 10, in one embodiment of the present disclosure, the liquid inlet cavity 54 and the liquid inlet section 522 are higher than the liquid outlet section 521, so that the cleaning liquid can naturally flow from the liquid inlet cavity 54 and the liquid inlet section 522 to the liquid outlet section 521 by using the self-gravity of the cleaning liquid, without the need for external power to provide power for the flow of the cleaning liquid, thereby saving the power source required by the pollution-bearing cleaning member 52.

[0250] Specifically, as shown in FIG. 12, in one embodiment of the present disclosure, the liquid inlet section 522 is higher than the liquid outlet section 521, and both ends of the liquid inlet section 522 are configured to extend downward along the wall of the pollution-containing part 31 to communicate with both ends of the liquid outlet section 521. Since both ends of the liquid inlet section 522 extend downward along the wall of the pollution-containing part 31 to communicate with both ends of the liquid outlet section 521, the cleaning liquid entering the liquid inlet section 522 can be naturally distributed into two parts and flow downward along the wall of the pollution-containing part 31 to both ends of the liquid outlet section 521, thereby automatically providing cleaning liquid to both ends of the liquid outlet section 521.

[0251] As shown in FIGS. 10, 12 and 24, in one embodiment of the present disclosure, the liquid outlet section 521 includes a flow guide groove 5211 extending circumferentially along the pollution-bearing part 32, and a flow guide plate 5212 covering the flow guide groove 5211, and the flow guide plate 5212 and the flow guide groove 5211 adjacent to one side of the inner cavity of the pollution-containing part 32 enclose an overflow port 5213; the cleaning liquid flowing in the flow guide groove 5211 is configured to flow into the inner cavity of the pollution-containing part 32 through the overflow port 5213. That is, the flow guide plate 5212 and the pollution-containing part 32 enclose the flow guide groove 5211, and the flow guide plate 5212 and the flow guide groove 5211 adjacent to one side of the inner cavity of the pollution-containing part 32 enclose the overflow port 5213, so that during the flow of the cleaning liquid along the flow guide groove 5211, part of the cleaning liquid can continuously flow into the inner cavity of the pollution-containing part 32 through the overflow port 5213, thereby cleaning the inner cavity of the pollution-containing part 32;

[0252] And the cleaning liquid entering from both ends of the liquid discharge section 521 will also flow into the inner cavity of the pollution receiving part 32 from the overflow port 5213 corresponding to the position after converging in the middle of the liquid discharge section 521, so as to clean the inner cavity of the pollution receiving part 32. Since the overflow port 5213 is formed on the side of the flow guide plate 5212 and the flow guide groove 5211 adjacent to the inner cavity of the pollution receiving part 32, and the overflow port 5213 is a ring-shaped overflow channel surrounding the first side wall 323, the second side wall 324 and the enclosing wall 322, it can be ensured that the inner cavity of the pollution receiving part 32 corresponding to the flow guide groove 5211 can be cleaned, and the cleaning dead angle can be avoided, and the dirt can be prevented from remaining on the inner cavity of the pollution receiving part 32.

[0253] Specifically, in one embodiment of the present disclosure, the flow guide groove 5211 is arranged on the outer side of the inner wall of the pollution receiving part 32, and the side of the flow guide plate 5212 facing the inner cavity of the pollution receiving part 32 is configured to extend from the top of the pollution receiving part 32 to the inner cavity of the pollution receiving part 32, so as to form the overflow port 5213 with the top end face of the pollution receiving part 32. That is, as shown in FIGS. 10 and 12, the flow guide groove 5211 is arranged on the radial outer side of the inner wall of the pollution receiving part 32, and the side of the flow guide plate 5212 facing the inner cavity of the pollution receiving part 32 extends from the top of the pollution receiving part 32 to the inner cavity of the pollution receiving part 32, so as to form the overflow port 5213 with the top end face of the pollution receiving part 32. In this way, when the liquid level of the cleaning liquid in the flow guide groove 5211 exceeds the top end face of the pollution receiving part 32, the cleaning liquid can flow out of the overflow port 5213 opening from the top of the flow guide groove 5211 to the inner cavity of the pollution receiving part 32, and then flow into the pollution receiving part 32 to clean the pollution receiving part 32.

[0254] It can be understood that, as shown in FIGS. 10 and 12, the radial outer side of the flow guide plate 5212 can be sealed with the outer side of the flow guide groove 5211, so as to avoid the cleaning liquid flowing out of the radial outer side of the flow guide groove 5211; and in another embodiment of the present disclosure, the flow guide plate 5212 can be formed with the outer wall of the pollution receiving part 32 to form the flow guide groove 521. Further, as shown in FIG. 10, in one embodiment of the present disclosure, the flow guide groove 5211 is arranged on the outer side of the inner wall of the pollution receiving part 32, and the side of the flow guide plate 5212 facing the inner cavity of the pollution receiving part 32 is configured to form a downward bending portion, and the bending portion and the inner wall of the pollution receiving part 32 form the overflow port 5213 opening downward.

[0255] That is, as shown in FIG. 10, the flow guide groove 5211 is arranged at the radially outer side of the pollution receiving part 32, and the radially outer side of the flow guide plate 5212 is sealed with the outer side of the flow guide groove 5211, so that the cleaning liquid can be prevented from flowing out from the radially outer side of the flow guide groove 5211; the radially inner side of the flow guide plate 5212 forms a downward bending part, and the bending part and the inner wall of the pollution receiving part 32 enclose an overflow port 5213 which is downwardly open and faces the inner cavity of the pollution receiving part 32, so that when the liquid level of the cleaning liquid in the flow guide groove 5211 exceeds the top end surface of the pollution receiving part 32, the cleaning liquid will flow to the inner side of the bending part, and then flow out from the overflow port 5213 under the blocking action of the bending part, so that the cleaning liquid can flow downward along the inner wall of the pollution receiving part 32 from the top end of the inner cavity of the pollution receiving part 32, and since the flow guide plate 5212 and the flow guide groove 5211 are arranged at the outer side of the inner wall of the pollution receiving part 32 rather than the inner side, the overflow port 5213 will not protrude from the inner wall of the pollution receiving part 32, so that a dead angle will not be formed below the connection position of the overflow port 5213 and the inner wall of the pollution receiving part 32, thereby enabling the cleaning liquid to clean all the inner walls of the pollution receiving part 32 and avoiding the formation of a cleaning dead angle in the pollution receiving part 32.

[0256] As shown in FIG. 12, in one embodiment of the present disclosure, at least two spaced-apart support parts 5214 are arranged between the flow guide plate 5212 and the top end surface of the pollution receiving part 32, and the flow guide plate 5212 is at least configured to be supported on the support parts 5214. In this way, the support parts 5214 support the flow guide part, so as to ensure that the overflow port 5213 can be formed between the flow guide plate 5212 and the top end surface of the pollution receiving part 32, and avoid the deformation of the flow guide plate 5212 and the blocking of part of the overflow port 5213, so that the cleaning liquid can normally flow.

[0257] It can be understood that the flow guide plate 5212 and the aforementioned cover plate 55 which participates in enclosing the liquid inlet cavity 54 can be fixedly connected or integrally formed, which is not limited herein.

[0258] As shown in FIGS. 10, 15 and 16, in one embodiment of the present disclosure, the cleaning base station 10 of the present disclosure further comprises a pollution containing cleaning part 51 which is arranged at the top of the inner cavity of the pollution containing part 31 and is configured to enclose a liquid outlet passage 511 with the top wall of the pollution containing part 31, and the cleaning liquid flowing out from the liquid outlet passage 511 is configured to flow downward at least along the inner wall of the pollution containing part 31.

[0259] Thus, during the operation of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning device 90 is discharged from the dirt discharge pipe 6 and into the dirt discharge tank 3, the dirt-containing cleaning member 51 can output the cleaning liquid from the top of the dirt-containing portion 31 to the inner cavity of the dirt-containing portion 31, thereby cleaning the inner cavity of the dirt-containing portion 31, preventing dirt from remaining on the inner cavity of the dirt-containing portion 31, ensuring that the dirt discharge tank 3 of the present disclosure is clean and odor-free, thereby effectively improving the user experience. Moreover, since the dirt-containing cleaning member 51 is arranged at the top of the inner cavity of the dirt-containing portion 31 and forms a liquid outlet passage 511 with the top wall of the dirt-containing portion 31, the cleaning liquid flowing out of the liquid outlet passage 511 flows downward along the top wall of the dirt-containing portion 31, thereby ensuring that the dirt-containing cleaning member 51 can clean the top of the inner cavity of the dirt-containing portion 31 and reducing the cleaning dead angle in the dirt-containing portion 31, especially eliminating the cleaning dead angle at the top of the dirt-containing portion 31, thereby reducing the dirt remaining in the inner cavity of the dirt-containing portion 31.

[0260] As shown in FIGS. 10 and 15, in an embodiment of the present disclosure, the liquid outlet of the liquid outlet passage 511 is arranged in the circumferential direction of the dirt-containing cleaning member 51 and is configured to output the cleaning liquid for cleaning the inner wall of the dirt-containing cavity in the circumferential direction of the dirt-containing cleaning member 51. In this way, the cleaning liquid can be output outwardly in the circumferential direction of the dirt-containing cleaning member 51, and since the dirt-containing cleaning member 51 is arranged at the top of the inner cavity of the dirt-containing portion 31, the cleaning liquid can be output outwardly in the circumferential direction of the top of the inner cavity of the dirt-containing portion 31, thereby ensuring that the cleaning liquid can clean everywhere in the circumferential direction of the inner cavity of the dirt-containing portion 31, avoiding the cleaning dead angle in the dirt-containing portion 31, especially at the top of the dirt-containing portion 31, preventing dirt from remaining in the inner cavity of the dirt-containing portion 31, and ensuring that the dirt-containing portion 31 of the present disclosure is clean and odor-free.

[0261] Specifically, as shown in FIG. 10, in an embodiment of the present disclosure, the dirt-containing portion 31 includes an upper first portion 311 and a lower second portion 312, the first portion 311 is configured to be in abutment with the second portion 312; the size of the first portion 311 is configured to be in a gradually expanding structure with the cross-sectional area increasing from top to bottom; the dirt-containing cleaning member 51 is arranged at the center of the inner cavity of the first portion 311 of the dirt-containing portion 31 and is configured to output the cleaning liquid in the circumferential direction of the dirt-containing cleaning member 51. Since the size of the upper first portion 311 of the dirt-containing portion 31 is in a gradually expanding structure with the cross-sectional area increasing from top to bottom, when the dirt-containing cleaning member 51 arranged at the center of the inner cavity of the first portion 311 of the dirt-containing portion 31 outputs the cleaning liquid in the circumferential direction of the dirt-containing cleaning member 51, it can ensure that the cleaning liquid everywhere in the circumferential direction can flow down along the inner wall of the dirt-containing portion 31 and clean everywhere in the circumferential direction of the inner cavity of the dirt-containing portion 31, further avoiding the cleaning dead angle in the dirt-containing portion 31.

[0262] Specifically, as shown in FIG. 10, in one embodiment of the present disclosure, the end face of the dirt-containing cleaning member 51 adjacent to the top wall of the dirt-containing portion 31 is configured to form an outflow channel 511 with the top wall of the dirt-containing portion 31; and the circumferential edge of the dirt-containing cleaning member 51 is configured to form an outflow port of the outflow channel 511. In this way, the cleaning liquid flowing from the through hole 56 on the top wall of the dirt-containing portion 31 into the outflow channel 511 formed by the end face of the dirt-containing cleaning member 51 adjacent to the top wall of the dirt-containing portion 31 and the top wall of the dirt-containing portion 31 will be output outward along the circumferential edge of the dirt-containing cleaning member 51 into the inner cavity of the dirt-containing portion 31, and the overall waterway structure is relatively simple.

[0263] Specifically, as shown in FIGS. 15 and 16, in one embodiment of the present disclosure, at least two partition portions 512 are arranged on the end face of the dirt-containing cleaning member 51, and the at least two partition portions 512 abut against the top wall of the dirt-containing portion 31; and / or at least two partition portions 512 are arranged on the top wall of the dirt-containing portion 31, and the at least two partition portions 512 abut against the end face of the dirt-containing cleaning member 51; the partition portions 512 cause the end face of the dirt-containing cleaning member 51 and the top wall of the dirt-containing portion 31 to form an outflow channel 511, and the partition portions 512 are configured to be arranged in the circumferential direction of the outflow channel 511.

[0264] That is, the partition portions 512 are arranged on one of the end face of the dirt-containing cleaning member 51 or the top wall of the dirt-containing portion 31 and abut against the other. Since the partition portions 512 are arranged in the circumferential direction of the outflow channel 511, the partition portions 512 cause the end face of the dirt-containing cleaning member 51 and the top wall of the dirt-containing portion 31 to form an outflow channel 511 and form a flow guide area 5111 in the outflow channel 511, so that the cleaning liquid can flow in the flow guide area 5111 formed by the partition portions 512.

[0265] Specifically, as shown in FIG. 15, in one embodiment of the present disclosure, the partition portions 512 are configured to extend in the radial direction of the outflow channel 511; and the two side walls of the partition portions 512 are configured to intersect in the direction adjacent to the outflow port and form a first end of the partition portions 512. Since the partition portions 512 extend in the radial direction of the outflow channel 511, and the two side walls of the partition portions 512 intersect in the direction adjacent to the outflow port and form a first end of the partition portions 512, that is, as shown in FIG. 15, the partition portions 512 are angular in the direction adjacent to the outflow port, and when the cleaning liquid from the left and right sides of the partition portions 512 flows along the two walls of the partition portions 512, a confluence area is formed, and the cleaning liquid will flow outward in the entire circumferential direction of the dirt-containing cleaning member 51, and no cleaning dead angle will be caused by the presence of the partition portions 512.

[0266] It can be understood that the extension of the partition portion 512 in the radial direction of the liquid outlet channel 511 refers to the extension from the center of the dirt-containing cleaning piece 51 to the periphery. As shown in FIG. 15, the second end of the partition portion 512 can be circular arc-shaped, so that the partition portion 512 as a whole is in the shape of a water droplet. The second end of the partition portion 512 can also be in other shapes, which are not limited herein.

[0267] Specifically, as shown in FIG. 15, in one embodiment of the present disclosure, the first end of the partition portion 512 is configured not to exceed the liquid outlet of the liquid outlet channel 511, and the region of the liquid outlet channel 511 between the first end of the partition portion 512 and the liquid outlet forms a confluence area 5112 that communicates with the flow guide area 5111.

[0268] In this way, the cleaning liquid can first flow along the flow guide area 5111 formed by the partition portion 512, and after flowing out of the flow guide area 5111, the cleaning liquid can flow to the confluence area 5112 of the liquid outlet channel 511 between the first end of the partition portion 512 and the liquid outlet, so as to converge with the cleaning liquid in the adjacent flow guide area 5111, thereby ensuring that the cleaning liquid is continuously distributed at each position of the periphery of the dirt-containing cleaning piece 51, without omission, and thus without a cleaning dead angle.

[0269] As shown in FIG. 15, in one embodiment of the present disclosure, in the radial direction of the dirt-containing cleaning piece 51, the end surface of the dirt-containing cleaning piece 51 at least includes a first inclined surface 515 adjacent to the edge position thereof and configured to extend downwardly and obliquely, and a second inclined surface 516 away from the edge position thereof and configured to extend upwardly and obliquely, the first inclined surface 515 and the second inclined surface 516 being transitionally connected; the partition portion 512 is configured to be located in the second inclined surface 516, and the first end of the partition portion 512 does not exceed the second inclined surface 516.

[0270] In this way, during the flow of the cleaning liquid along the second inclined surface 516, the gap between the end surface of the dirt-containing cleaning piece 51 and the inner wall of the dirt-containing portion 31 can be continuously reduced, and the cleaning liquid can be squeezed, so that when the cleaning liquid flows between the flow guide areas 5111 formed by the partition portion 512, the cleaning liquid will not be interrupted at each position of the periphery; after the cleaning liquid flows to the first inclined surface 515 at the edge position of the dirt-containing cleaning piece 51, since the first inclined surface 515 extending downwardly and obliquely matches the profile of the top inner wall of the dirt-containing portion 31, it can be ensured that the cleaning liquid can flow toward the direction of the inner wall of the dirt-containing portion 31 to clean the inner wall of the dirt-containing portion 31. The end surface of the dirt-containing cleaning piece 51 can be an arc-shaped curved surface or a flat slope, which is not limited herein.

[0271] In one embodiment of the present disclosure, the cleaning base station 10 of the present disclosure further comprises an elastic member, the dirt-containing cleaning member 51 is configured to be pre-pressed on the top wall of the dirt-containing part 31 by the elastic member, the dirt-containing cleaning member 51 is configured to move away from the top wall of the dirt-containing part 31 when an external force greater than a threshold value is applied, and to move towards the top wall of the dirt-containing part 31 under the action of the elastic member when the external force is less than the threshold value. In this way, when no cleaning liquid flows out of the through hole 56 or the water pressure of the cleaning liquid is small, the dirt-containing cleaning member 51 can move towards the top wall of the dirt-containing part 31 under the action of the elastic force of the elastic member, thereby being pressed on the top wall of the dirt-containing part 31 to block the top wall of the dirt-containing part 31. And when the water pressure of the cleaning liquid becomes small, the dirt-containing cleaning member 51 can move towards the top wall of the dirt-containing part 31 under the action of the elastic force of the elastic member, thereby narrowing the liquid outlet channel 511, keeping the liquid outlet channel 511 continuously flowing and maintaining a certain liquid outlet pressure during liquid outlet, thereby improving the flushing effect of the dirt-containing cleaning member 51.

[0272] When the water pressure of the cleaning liquid flowing out of the through hole 56 is large, greater than the threshold value, the dirt-containing cleaning member 51 can move away from the top wall of the dirt-containing part 31 under the action of the water pressure of the cleaning liquid, naturally opening the liquid outlet channel 511, so that the cleaning liquid can be continuously output along the circumference of the dirt-containing cleaning member 51, to ensure that the water pressure of the cleaning liquid for cleaning the dirt-containing part 31 is large, thereby meeting the cleaning demand.

[0273] As shown in FIGS. 7 and 10, in one embodiment of the present disclosure, the dirt discharge groove 3 comprises a dirt receiving part 32 communicating with the inner cavity of the dirt-containing part 31, and a dirt receiving opening 321 provided at the top of the dirt receiving part 32 is configured to be lower than the top of the dirt-containing part 31; the dirt-containing part 31 is provided with a baffle 33 adjacent to one side of the dirt receiving part 32, and the baffle 33 is configured to extend downward from the top wall of the dirt-containing part 31 to a position adjacent to the dirt receiving opening 321. Since the dirt-containing part 31 is provided with the baffle 33 adjacent to one side of the dirt receiving part 32, and the baffle 33 extends downward from the top wall of the dirt-containing part 31 to a position adjacent to the dirt receiving opening 321, it can avoid the cleaning liquid output by the dirt-containing cleaning member 51 from flowing to the inner wall of the dirt receiving part 32, interfering with the cleaning liquid output by the dirt receiving cleaning member 52, and also preventing the cleaning liquid from being splashed out of the dirt receiving opening 321.

[0274] As shown in FIG. 3, in one embodiment of the present disclosure, the cleaning base station 10 of the present disclosure further comprises a blockage sensor 8, the blockage sensor 8 is arranged at a detection position 81 of the dirt discharge groove 3, and the blockage sensor 8 is configured to be triggered when blockage occurs at the detection position 81; wherein the volume of the cleaning base station 10 below the detection position 81 is configured to be greater than 80% of the volume of the sewage bucket 92.

[0275] Specifically, the blockage sensor 8 is usually an optical sensor, including a light emitting end and a light receiving end. When the 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 the liquid signal.

[0276] Assuming that the sewage tank 92 of the cleaning device 90 is full, and the required time for discharging sewage from the sewage slot 3 without blockage is t1, during the t1 time required for the sewage discharge process, the dirt will continue to flow through the blockage sensor 8, and the blockage sensor 8 will detect the liquid signal for a maximum of t1. When blockage occurs in the sewage slot 3, and the blockage water level reaches the blockage sensor 8, the blockage sensor 8 detects the liquid signal. If the continuous time of the liquid signal detected by the liquid level sensor 8 is greater than t1, it can be determined that the sewage blockage occurs.

[0277] In the existing cleaning base station, the volume below the detection position 81 in the sewage slot 3 is small, and when the sewage amount is large, the dirt is easy to accumulate at the detection position 81, but in fact no blockage occurs, so false positives may occur. In the working process of the cleaning base station 10 of the present disclosure, the floor brush assembly 94 of the cleaning device 90 is placed on the tray 2, and the sewage outlet 93 of the cleaning device 90 is connected with the sewage receiving port 321 of the sewage slot 3, and the dirt in the sewage tank 92 will flow into the sewage slot 3. Since the blockage sensor 8 is arranged in the sewage slot 3 and can be triggered when the liquid level of the dirt in the sewage slot 3 reaches the detection position 81, when the cleaning base station 10 of the present disclosure is blocked, the liquid level of the dirt in the sewage slot 3 reaches the detection position 81, the blockage sensor 8 can be triggered in time, which facilitates the cleaning base station 10 of the present disclosure to accelerate the sewage discharge, thereby removing the dirt blocked in the sewage pipeline 6, or performing other subsequent steps.

[0278] Since the volume below the detection position 81 in the cleaning base station 10 is greater than 80% of the volume of the sewage tank 92, even when the sewage amount is large, the dirt is not easy to accumulate at the detection position 81, thereby effectively avoiding false positives.

[0279] Further, in an embodiment of the present disclosure, the volume above the detection position 81 in the sewage slot 3 is configured to be greater than the volume of the sewage tank 92.

[0280] When the cleaning device 90 starts to discharge sewage, if the cleaning base station 10 is blocked, the sewage in the sewage discharge groove 3 cannot be smoothly discharged, and the liquid level of the sewage reaches the detection position 81, the blockage sensor 8 can be triggered in time, so that the cleaning base station 10 can be processed. When the cleaning device 90 starts to discharge sewage, if the cleaning base station 10 is blocked, the sewage in the sewage discharge groove 3 cannot be smoothly discharged, and the liquid level of the sewage does not reach the detection position 81, the blockage sensor 8 will not be triggered. When the cleaning device 90 discharges sewage again, the sewage in the sewage discharge groove 3 continues to accumulate, and the liquid level of the sewage in the sewage discharge groove 3 reaches the detection position 81, and the blockage sensor 8 is triggered. However, the sewage discharge process of the cleaning device 90 will not stop, but will continue until the sewage bucket 92 is empty. At this time, since the volume above the detection position 81 in the sewage discharge groove 3 is greater than the volume of the sewage bucket 92, even if the sewage discharge groove 3 does not reach the detection position 81 at the end of the first sewage discharge, and the blockage sensor 8 is not triggered, the sewage discharge groove 3 can continue to accommodate all the sewage in the sewage bucket 92 during the second sewage discharge, and the sewage will not overflow from the sewage bucket 92. Therefore, the situation that the sewage in the sewage discharge groove 3 pollutes the cleaning base station 10 is prevented, the use burden of the user is effectively reduced, and the use experience of the user is improved.

[0281] Specifically, in an embodiment of the present disclosure, the sewage discharge groove 3 comprises a sewage containing part 31 and a sewage receiving part 32 in communication with the inner cavity of the sewage containing part 31; the detection position 81 is located in the inner cavity of the sewage containing part 31; wherein the volume above the detection position 81 comprises the part above the detection position 81 in the sewage containing part 31 and the part above the detection position 81 in the sewage receiving part 32. It can be understood that the part above the detection position 81 in the sewage containing part 31 and the part above the detection position 81 in the sewage receiving part 32 can be used to temporarily store sewage, so that when the cleaning base station 10 is blocked, the sewage in the sewage discharge groove 3 can be prevented from overflowing to pollute the cleaning base station 10, and the required volume in the sewage discharge groove 3 can be effectively reduced, thereby facilitating the miniaturization of the cleaning base station 10 of the present disclosure.

[0282] Specifically, as shown in FIG. 7, in an embodiment of the present disclosure, the top of the sewage receiving part 32 is configured to extend outward from the sewage containing part 31 to form a sewage receiving opening 321, the opening direction of the sewage receiving opening 321 is configured to be upward, and is configured to be used for docking with the sewage discharge opening 93 of the cleaning device 90; the volume above the detection position 81 comprises the part from the detection position 81 to the sewage receiving opening 321 in the sewage containing part 31 and the sewage receiving part 32. Since the volume above the detection position 81 comprises the part from the detection position 81 to the sewage receiving opening 321 in the sewage containing part 31 and the sewage receiving part 32, when the cleaning base station 10 is blocked, the sewage in the sewage receiving part 32 can be prevented from overflowing to pollute the cleaning base station 10.

[0283] As shown in FIG. 7, in one embodiment of the present disclosure, the top end surface of the pollution receiving port 321 is configured to be lower than the top of the pollution receiving portion 31. In the case that the top end surface of the pollution receiving port 321 is lower than the top of the pollution receiving portion 31, the detection position 81 can be arranged below the top end surface of the pollution receiving port 321, and the portion of the volume that meets the above requirements ensures that the blockage sensor 8 can normally trigger the blockage.

[0284] As shown in FIG. 4 and FIG. 7, in one embodiment of the present disclosure, the pollution receiving portion 32 is connected to one side of the pollution receiving portion 31, and the pollution receiving portion 32 has a pollution discharging surface 325 extending to communicate with the inner cavity of the pollution receiving portion 31, and at least part of the dirty discharged from the pollution discharging port 93 is configured to flow from the pollution discharging surface 325 to the inner cavity of the pollution receiving portion 31; the detection position 81 is configured to be arranged on the side of the inner cavity of the pollution receiving portion 31 away from the pollution discharging surface 325.

[0285] In this way, during the operation of the cleaning base station 10 of the present disclosure, the pollution discharging surface 325 of the pollution receiving portion 32 can receive the dirty discharged from the pollution discharging port 93 of the cleaning device 90, and guide the dirty discharged from the cleaning device 90 to flow into the inner cavity of the pollution receiving portion 31. Since the detection position 81 is arranged on the side of the inner cavity of the pollution receiving portion 31 away from the pollution discharging surface 325, the dirty flowing along the pollution discharging surface 325 is less likely to impact the blockage sensor 8 on the detection position 81, thereby reducing the probability of false positives of the blockage sensor 8.

[0286] Further, in one embodiment of the present disclosure, the detection position 81 is configured to be not lower than the bottom end of the pollution discharging surface 325. When the dirty flows along the pollution discharging surface 325 of the pollution receiving portion 32 to the inner cavity of the pollution receiving portion 31, since the detection position 81 is not lower than the bottom end of the pollution discharging surface 325, even if the flow speed is fast, the dirty flowing into the inner cavity of the pollution receiving portion 31 will not directly impact the blockage sensor 8 on the detection position 81, thereby effectively avoiding false positives of the blockage sensor 8.

[0287] In one embodiment of the present disclosure, the volume of the pollution discharging groove 3 above the detection position 81 is configured to be greater than the volume of the pollution discharging groove 3 below the detection position 81. Since the volume of the pollution discharging groove 3 above the detection position 81 is configured to be greater than the volume of the pollution discharging groove 3 below the detection position 81, it can be ensured that the volume of the pollution discharging groove 3 above the detection position 81 meets the requirements, and under the premise that the dirty overflows from the pollution discharging groove 3 to pollute the cleaning base station 10, the required volume of the pollution discharging groove 3 is reduced, thereby facilitating the miniaturization of the cleaning base station 10 of the present disclosure.

[0288] In another embodiment of the present disclosure, the volume of the cleaning base station 10 below the detection position 81 is 0.8 to 1.2 times the volume of the sewage tank 92. Since the volume of the sewage tank 3 below the detection position 81 is 0.8 to 1.2 times the volume of the sewage tank 92, and since it takes a certain period of time for the cleaning base station 10 of the present disclosure to discharge the dirt, the portion of the sewage tank 3 below the detection position 81 can temporarily store the dirt during the process of discharging the dirt in the cleaning base station 10 of the present disclosure, so that after the dirt in the cleaning equipment 90 is quickly discharged into the sewage tank 3, the liquid level of the dirt does not reach the detection position 81, and the clogging sensor 8 is not triggered, preventing the liquid level of the dirt from reaching the detection position 81 during each discharge process, which may cause the clogging sensor 8 to malfunction. It can be understood that the volume of the cleaning base station 10 below the detection position 81 not only includes the portion of the sewage tank 3 below the detection position 81, but also includes the volume of the sewage pipe 6.

[0289] In an embodiment of the present disclosure, the control unit of the present disclosure is configured to send an alarm information based on the electrical signal triggered by the clogging sensor 8. In this way, when the clogging sensor 8 is triggered, the control unit can timely send an alarm information to inform the user to perform maintenance or other work.

[0290] In an embodiment of the present disclosure, if the clogging sensor 8 detects clogging, the self-cleaning is cancelled, and a prompt and charging are performed. In another embodiment of the present disclosure, if clogging occurs, the jet flow component can be allowed to work for a period of time (for example, 3s), and the jet flow component can work in the original water flow size or in an increased water flow size to increase the dirt flushing power. The period of time is related to the volume of the sewage tank above the clogging sensor (900ml) and the flow rate of the jet flow component (8L / min to 15L / min), and water cannot overflow. After waiting for a period of time (for example, 5s), if the sewage tank is still clogged, the self-cleaning is cancelled, and a prompt and charging are performed.

[0291] It can be understood that in the case where the cleaning base station 10 of the present disclosure is provided with the aforementioned jet flow assembly 7, the cleaning base station 10 of the present disclosure controls the jet flow assembly 7 to work for a period of time to accelerate the flow of dirt in the sewage pipe 6 and flush away the clogged dirt in the sewage pipe 6 while sending an alarm information. However, in the case where the clogging is too serious to be flushed away, the user can only manually clean it up.

[0292] In one embodiment of the present disclosure, the dirt discharging groove 3 is provided with a dirt receiving port 321 for docking with the dirt discharging port 93 of the cleaning device 90; and the dirt discharging groove 3 is configured to rotate between a first position and a second position, the dirt receiving port 321 is located at the front side of the tray 2 in the first position, and the dirt receiving port 321 is located in the base 1 in the second position. In this way, when the cleaning device 90 needs to be docked with the cleaning base station 10 for dirt discharging, the dirt discharging groove 3 can be rotated to the first position, the dirt discharging port 93 of the cleaning device 90 can be docked with the dirt receiving port 321 of the dirt discharging groove 3, and the dirt in the cleaning device 90 can be discharged into the cleaning base station 10 through the dirt receiving port 321; and when dirt discharging is not needed, the dirt discharging groove 3 can be rotated to the second position, so that the dirt receiving port 321 is accommodated in the base 1, thereby hiding the dirt receiving port 321 and preventing the dirt discharging groove 3 from having a return smell, effectively improving the user experience. Specifically, the rotation of the dirt discharging groove 3 can be controlled by using a motor or other mechanical transmission device, and the specific principle can refer to other existing technologies, which will not be described here. In another embodiment, the rotation of the dirt discharging groove 3 can also be achieved by docking the cleaning device 90 with the cleaning base station 10. Specifically, a first trigger member can be provided on the base station 10, and the first trigger member has an initial state and a first state. When the cleaning device 90 is docked with the base station 10, the cleaning device 90 abuts against the first trigger member, so that the first trigger member changes from the initial state to the first state, thereby driving the dirt discharging groove 3 to rotate to the first position. When the cleaning device 90 is removed from the base station 10, the first trigger member returns to the initial state from the first state, thereby driving the dirt discharging groove 3 to rotate to the second position.

[0293] In one embodiment of the present disclosure, the dirt discharging groove 3 is provided with a dirt receiving port 321 for docking with the dirt discharging port 93 of the cleaning device 90; and the dirt receiving port 321 is provided with a partition plate configured to open or close the dirt receiving port 321. Specifically, the partition plate can rotate or translate relative to the dirt receiving port 321 to open or close the dirt receiving port 321, and the specific principle is not limited.

[0294] When the cleaning device 90 needs to be connected with the cleaning base station 10 for sewage discharge, the partition plate can be opened, and the sewage discharge port 93 of the cleaning device 90 can be connected with the sewage receiving port 321 of the sewage discharge groove 3, so that the dirt in the cleaning device 90 can be discharged into the cleaning base station 10 through the sewage receiving port 321; when no sewage discharge is needed, the sewage receiving port 321 can be closed by the partition plate, so as to hide the sewage receiving port 321 and prevent the sewage discharge groove 3 from returning, thereby effectively improving the user experience. Specifically, the movement of the partition plate can be controlled by using a motor or other mechanical transmission device, and the specific principle can refer to other prior art, which will not be described here. In another embodiment, the movement of the partition plate can also be realized by connecting the cleaning device 90 with the cleaning base station 10. Specifically, a second trigger member can be arranged on the base station 10, and the second trigger member has an initial state and a second state. When the cleaning device 90 is connected with the base station 10, the cleaning device 90 abuts against the second trigger member, so that the second trigger member changes from the initial state to the second state, thereby driving the partition plate to move to open the sewage receiving port 321. When the cleaning device 90 is removed from the base station 10, the second trigger member returns to the initial state from the second state, thereby driving the partition plate to move to close the sewage receiving port 321.

[0295] As shown in FIG. 10, in one embodiment of the present disclosure, the sewage discharge groove 3 includes a sewage containing portion 31, which includes a gradually expanding portion with gradually increasing cross-sectional area from top to bottom and a gradually reducing portion with gradually decreasing cross-sectional area from top to bottom. The gradually expanding portion is connected above the gradually reducing portion, and the detection position 81 is located at the bottom end of the gradually expanding portion and the connection position of the gradually reducing portion. That is, the detection position 81 is located at the bottom end of the first portion 311 and the connection position of the gradually reducing portion, which can increase the volume below the detection position 81 when the blockage occurs, thereby reducing the probability of false alarm when the sewage speed is slow. At the same time, since the bottom end of the gradually expanding portion of the sewage containing portion 31 and the connection position of the gradually reducing portion are very obvious, the staff can easily install the blockage sensor 8 without positioning the detection position 81 before installation.

[0296] As shown in FIGS. 1 to 3, the present disclosure also provides a cleaning system, which includes a cleaning device 90 and a cleaning base station 10. The cleaning device 90 includes a machine body 91, and a sewage discharge port 93 arranged on the machine body 91.

[0298] The present disclosure provides a cleaning base station 10 used in combination with a cleaning device 90 for cleaning work. The cleaning base station 10 comprises a base 1, a tray 2 and a sewage tank 3; the base 1 is configured to extend in the height direction and is used to install various functional elements required by the cleaning base station 10 such as the sewage tank 3. The tray 2 is arranged at the bottom of the base 1 and extends to the front side in the horizontal direction relative to the base 1, and the side opposite to the front side is referred to as the rear side. The sewage tank 3 comprises a sewage containing part 31 located in the cleaning base station 10 and a sewage receiving part 32 communicating with the inner cavity of the sewage containing part 31; the sewage receiving part 32 is located at the front side of the sewage containing part 31 and is configured to be connected to the side wall of the sewage containing part 31 to form a containing cavity together with the sewage containing part 31.

[0299] During the operation of the cleaning base station 10 of the present disclosure, the cleaning device 90 is placed on the tray 2, the sewage outlet 93 of the cleaning device 90 is located above the sewage receiving part 32, and the sewage discharged by the cleaning device 90 can be discharged into the sewage tank 3. Among them, the sewage receiving part 32 is located at the front side of the sewage containing part 31 and is connected to the side wall of the sewage containing part 31, mainly used for receiving the sewage discharged by the cleaning device 90, and guiding the sewage discharged by the cleaning device 90 into the sewage containing part 31; the sewage containing part 31 is arranged in the base 1, mainly used for temporarily storing sewage, and guiding the sewage discharged by the cleaning device 90 into the sewage pipeline 6 to discharge the sewage to the outside.

[0300] Since the sewage receiving part 32 is located at the front side of the sewage containing part 31 and is connected to the side wall of the sewage containing part 31, it protrudes forward from the base 1, and the sewage containing part 31 is located in the base 1, which can effectively optimize the layout of the cleaning base station 10 of the present disclosure, save space, and facilitate the miniaturization of the cleaning base station 10. Moreover, when the sewage tank 3 is blocked, the sewage receiving part 32 and the sewage containing part 31 can jointly contain the sewage to prevent the sewage from overflowing from the sewage tank 3. Compared with the existing cleaning base station 10, the overall volume of the sewage tank 3 of the cleaning base station 10 of the present disclosure is larger and occupies less space, effectively improving the user experience.

[0301] Application scenario 2

[0302] The present disclosure provides a cleaning base station 10 for cleaning work in combination with a cleaning device 90, specifically, the cleaning base station 10 comprises a base 1, a tray 2, a sewage tank 3 and a sewage pipeline 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, and the tray 2 is provided with a rolling brush groove 21 for accommodating the rolling brush of the cleaning device 90, and the axis direction of the rolling brush groove 21 is the first direction; the sewage tank 3 is arranged in the cleaning base station 10; the sewage pipeline 6 is configured to communicate with the bottom of the sewage tank 3; the sewage pipeline 6 at least has a sewage section 62 extending in the transverse direction, 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 towards 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 towards the sewage section 62 to communicate with the sewage section 62; the sewage section 62 extends along the first direction.

[0303] In the working process of the cleaning base station 10 of the present disclosure, the floor brush assembly 94 of the cleaning device 90 is placed on the tray 2, and the sewage outlet 93 of the cleaning device 90 discharges dirt into the sewage tank 3 in the base 1, and the dirt flows into the connecting section 61 of the sewage pipeline 6 from the bottom of the sewage tank 3, and then flows along the sewage section 62, since the sewage section 62 extends along the first direction, the overall width of the cleaning base station 10 can be effectively utilized to arrange the sewage section 62, thereby reducing the length of the cleaning base station 10 of the present disclosure in the second direction. Moreover, since the sewage section 62 extends along the first direction, the dirt only needs to experience one turn in the connecting section 61 during the flowing process to the sewage section 62, the extension direction of the sewage section 62 is consistent with that of the external extension pipe connected to the sewage outlet of the base, thereby effectively reducing the kinetic energy loss of the dirt during the sewage process, and the sewage is more smooth.

[0304] Application scenario 3

[0305] The present disclosure provides a cleaning base station 10, comprising a base 1, a tray 2 and a sewage tank 3, the base 1 is configured to extend in the height direction; the tray 2 is located at the bottom of the base 1 and is configured to extend in the horizontal direction; one side of the base 1 where the tray 2 is arranged is recorded as the front side, and the side opposite to it is recorded as the rear side; the sewage tank 3 comprises a sewage containing part 31 located in the base and a sewage receiving part 32 communicating with the inner cavity of the sewage containing part 31; the sewage receiving part 32 is configured to have a sewage receiving opening 321 for docking with the sewage outlet 93 of the cleaning device 90; the sewage receiving part 32 has a sewage discharge surface 325, and at least part of the dirt flowing from the sewage receiving opening 321 is configured to be guided from the sewage discharge surface 325 to the inner cavity of the sewage containing part 31; the area of the sewage discharge surface 325 corresponding to the sewage outlet 93 is configured to be a flat surface or a continuous and smooth curved surface.

[0306] In the working process of the cleaning base station 10 of the present disclosure, the cleaning device 90 is placed on the tray 2, the pollution discharge port 93 of the cleaning device 90 is located above the pollution receiving portion 32, and the dirt discharged by the cleaning device 90 can be discharged into the pollution discharge groove 3. Among them, the pollution discharge surface 325 of the pollution receiving portion 32 can receive the dirt discharged from the pollution discharge port 93 of the cleaning device 90, and guide the dirt discharged by the cleaning device 90 to flow into the inner cavity of the pollution receiving portion 31, that is, at least part of the dirt flowing out of the pollution discharge port 93 can flow from the pollution discharge surface 325 to the inner cavity of the pollution receiving portion 31; the pollution receiving portion 31 is arranged in the base 1, mainly used for temporarily storing dirt, and guiding the dirt discharged by the cleaning device 90 to flow into the pollution discharge pipeline 6, so that the dirt is discharged to the outside. Specifically, since the area of the pollution discharge surface 325 corresponding to the pollution discharge port 93 is configured as a flat surface or a continuous and smooth curved surface, when the dirt falls from the pollution receiving port 321 to the pollution discharge surface 325, it will flow smoothly downward, ensuring that the dirt continues to flow to the pollution discharge pipeline 6 with a large kinetic energy, and can also avoid the dirt splashing out of the pollution receiving port 321 when falling on the pollution discharge surface 325, falling on the base 1 or the tray 2 of the cleaning base station 10, without the need for the user to clean the cleaning base station 10 twice, effectively reducing the user's use burden, and improving the user's use experience.

[0307] Application scenario 4

[0308] The present disclosure provides a cleaning base station 10 for cleaning work with a cleaning device 90, specifically, the cleaning base station 10 includes a base 1, a pollution discharge groove 3 and a base station self-cleaning assembly 5; the base 1 is configured to extend in the height direction; the pollution discharge groove 3 includes a pollution receiving portion 31 located in the base 1 and a pollution receiving portion 32 communicating with the inner cavity of the pollution receiving portion 31, the pollution receiving portion 32 is configured to be connected to the side wall of the pollution receiving portion 31; the base station self-cleaning assembly 5 is located at the top of the pollution discharge groove 3, and the base station self-cleaning assembly 5 is configured to output cleaning liquid from the top of the pollution receiving portion 31 to the inner cavity of the pollution receiving portion 31, and output cleaning liquid from the top of the pollution receiving portion 31 to the top of the pollution receiving portion 32 and the inner cavity of the pollution receiving portion 32.

[0309] In the working process of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning equipment 90 is discharged into the dirt discharging groove 3 and discharged from the dirt discharging pipeline 6, the base station self-cleaning assembly 5 can output cleaning liquid from the top of the dirt containing part 31 to the inner cavity of the dirt containing part 31, and output cleaning liquid from the top of the dirt containing part 31 to the top of the dirt receiving part 32 and the 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 from remaining on the inner cavities of the dirt containing part 31 and the dirt receiving part 32, ensuring that the dirt discharging groove 3 of the present disclosure is clean and odorless, thereby effectively improving the user experience. Moreover, since the base station self-cleaning assembly 5 can output cleaning liquid from the top of the dirt containing part 31 to the inner cavities of the dirt containing part 31 and the dirt receiving part 32, it is not necessary to separately provide a cleaning mechanism for the dirt containing part 31 and the dirt receiving part 32, which can effectively simplify the waterway structure of the cleaning base station 10 of the present disclosure and promote the miniaturization of the cleaning base station 10 of the present disclosure.

[0310] Application scenario 5

[0311] The present disclosure provides a cleaning base station 10 for cleaning work in combination with a cleaning equipment 90, specifically, the cleaning base station 10 comprises a base 1, a dirt discharging groove 3 and a dirt receiving cleaning piece 52; the base 1 is configured to extend in the height direction; the dirt discharging groove 3 comprises a dirt receiving part 32 having a dirt receiving port 321, the dirt receiving port 321 is configured to be connected to the dirt discharging port 93 of the cleaning equipment 90; the dirt receiving cleaning piece 52 is arranged around the dirt receiving port 321 and is configured to output cleaning liquid to the inner cavity of the dirt receiving part 32; the dirt receiving cleaning piece 52 comprises a liquid inlet section 522 and a liquid outlet section 521, the liquid outlet section 521 is configured to communicate with the liquid inlet section 522 and is arranged at a position lower than the liquid inlet section 522; the cleaning liquid is configured to flow from the liquid inlet section 522 to the liquid outlet section 521 and is configured to flow from the liquid outlet section 521 to the inner cavity of the dirt receiving part 32.

[0312] In this way, in the working process of the cleaning base station 10 of the present disclosure, after the dirt discharged by the dirt discharging port 93 of the cleaning equipment 90 is discharged into the dirt discharging groove 3 and discharged from the dirt discharging pipeline 6, the dirt receiving cleaning piece 52 can output cleaning liquid to the inner cavity of the dirt receiving part 32 to clean the inner cavity of the dirt receiving part 32. Since the dirt receiving cleaning piece 52 is arranged around the dirt receiving port 321, the dirt receiving cleaning piece 52 can clean the inner cavity of the dirt receiving part 32 when outputting cleaning liquid, preventing dirt from remaining on the inner cavity of the dirt receiving part 32, ensuring that the dirt receiving part 32 of the present disclosure is clean and odorless, thereby effectively improving the user experience.

[0313] Moreover, since the pollution-accepting cleaning member 52 comprises the liquid-inlet section 522, the liquid-discharge section 521, the liquid-discharge section 521 is in communication with the liquid-inlet section 522, and is arranged at a position lower than the liquid-inlet section 522, thus the cleaning liquid can flow from the liquid-inlet section 522 to the liquid-discharge section 521 under the action of its own gravity, and then flow from the liquid-discharge section 521 to the inner cavity of the pollution-accepting section 32, without the need for external power to provide the flow of the cleaning liquid, thus the power source required by the pollution-accepting cleaning member 52 can be omitted, so as to effectively simplify the waterway structure of the cleaning base station 10 of the present disclosure, and promote the miniaturization of the cleaning base station 10 of the present disclosure.

[0314] Application scenario 6

[0315] The present disclosure provides a cleaning base station 10 for cleaning work in combination with a cleaning device 90, specifically, the cleaning base station 10 comprises a base 1, a pollution discharge tank 3 and a pollution-accepting cleaning member 51; the base 1 is configured to extend in the height direction; the pollution discharge tank 3 comprises a pollution-accepting section 31 located in the base 1; the pollution-accepting cleaning member 51 is arranged at the top of the inner cavity of the pollution-accepting section 31, and is configured to surround an outlet passage 511 with the top wall of the pollution-accepting section 31, and the cleaning liquid flowing out of the outlet passage 511 is configured to flow downward at least along the inner wall of the pollution-accepting section 31.

[0316] Thus, during the working process of the cleaning base station 10 of the present disclosure, after the dirt discharged by the cleaning device 90 is discharged from the pollution discharge pipeline 6 and then discharged into the pollution discharge tank 3, the pollution-accepting cleaning member 51 can output cleaning liquid from the top of the pollution-accepting section 31 to the inner cavity of the pollution-accepting section 31, so as to clean the inner cavity of the pollution-accepting section 31, prevent dirt from remaining on the inner cavity of the pollution-accepting section 31, and ensure that the pollution discharge tank 3 of the present disclosure is clean and odorless, thus effectively improving the user experience.

[0317] Moreover, since the pollution-accepting cleaning member 51 is arranged at the top of the inner cavity of the pollution-accepting section 31, and surrounds the outlet passage 511 with the top wall of the pollution-accepting section 31, and the cleaning liquid flowing out of the outlet passage 511 flows downward at least along the inner wall of the pollution-accepting section 31, thus ensuring that the pollution-accepting cleaning member 51 can clean the top of the inner cavity of the pollution-accepting section 31, reduce the cleaning dead angle in the pollution-accepting section 31, and thus reduce the remaining of dirt in the inner cavity of the pollution-accepting section 31.

[0318] Application scenario 7

[0319] The present disclosure provides a cleaning base station 10 configured to be docked with a cleaning device 90, and comprising a base 1 configured to extend in a height direction, a sewage tank 3 provided with a sewage receiving port 321 configured to be docked with a sewage outlet 93 of the cleaning device 90, and a blockage sensor 8 provided at a detection position 81 of the sewage tank 3 and configured to be triggered when the detection position 81 is blocked by sewage, wherein a volume of the base station below the detection position 81 is configured to be greater than 80% of a volume of a sewage tank 92 of the cleaning device 90.

[0320] During the operation of the cleaning base station 10 of the present disclosure, the floor brush assembly 94 of the cleaning device 90 is placed on the tray 2, the sewage outlet 93 of the cleaning device 90 is docked with the sewage receiving port 321 of the sewage tank 3, and the dirt in the sewage tank 92 flows into the sewage tank 3. Since the blockage sensor 8 is provided in the sewage tank 3 and can be triggered when the liquid level of the dirt in the sewage tank 3 reaches the detection position 81, the blockage sensor 8 can be triggered in time when the cleaning base station 10 of the present disclosure is blocked and the liquid level of the dirt in the sewage tank 3 reaches the detection position 81, so that the cleaning base station 10 of the present disclosure can accelerate the sewage discharge to remove the blocked dirt in the sewage pipeline 6 or perform other subsequent steps.

[0321] Since the volume of the cleaning base station 10 below the detection position 81 is greater than 80% of the volume of the sewage tank 92, even when the sewage volume is large, the dirt is not easy to accumulate at the detection position 81, thereby effectively avoiding false alarms.

[0322] The present disclosure also provides a cleaning device comprising a body and a sewage tank, the sewage tank comprising a tank body, a self-cleaning assembly, and a cover; wherein the tank body is configured to enclose an inner cavity with an opening; the self-cleaning assembly is configured to be detachably mounted on the upper part of the tank body and is configured to output cleaning liquid to at least clean the inner wall of the tank body; the cover is provided with a gas pipeline and a gas-liquid separation assembly; and the cover is detachably mounted on the opening of the tank body and is located in the dismounting path of the self-cleaning assembly.

[0323] In this way, in the cleaning device of the present disclosure, the inner cavity in the tank body can be used to contain dirt, and during operation, the gas pipeline on the cover of the sewage tank can be in communication with the fan unit, and the fan unit can form a negative pressure in the inner cavity of the tank body, thereby sucking the dirt on the working surface into the inner cavity. Since the gas-liquid separation assembly is provided on the cover, the dirt droplets can be prevented from entering the fan unit from the cover.

[0324] When the cleaning device of the present disclosure is used with the cleaning base station capable of automatically discharging sewage, the cleaning device of the present disclosure can be placed on the cleaning base station, and then the dirt in the sewage tank is automatically discharged into the cleaning base station. After the discharge of the dirt is completed, the self-cleaning assembly can be used to output cleaning liquid to clean at least the inner wall of the barrel body, thereby cleaning the residual dirt on the inner wall of the sewage tank, without the need for the user to manually clean the inside of the sewage tank, which helps to reduce the user's use burden and greatly improves the user's use experience.

[0325] Moreover, since the self-cleaning assembly is detachably installed on the upper part of the barrel body, and the cover is detachably installed on the opening of the barrel body and located in the dismounting path of the self-cleaning assembly, when assembling the sewage tank of the present disclosure, only the self-cleaning assembly needs to be placed on the upper part of the barrel body, and then the cover is installed on the opening of the barrel body.

[0326] When there is stubborn dirt in the barrel body that is difficult to remove, the user can dismount the sewage tank from the machine, and then dismount the cover and the self-cleaning assembly from the barrel body in sequence, and flush the barrel body, the cover and the self-cleaning assembly respectively to remove the stubborn dirt on the inner cavity of the sewage tank, thereby achieving deep cleaning of each part of the sewage tank, preventing bacteria from breeding in the sewage tank and effectively avoiding hygiene problems.

[0327] For ease of understanding, the specific structure of the cleaning device of the present disclosure and its working principle will be described in detail below with reference to FIGS. 25-35 in combination with an embodiment.

[0328] As shown in FIGS. 25-27 and 34, the present disclosure provides a cleaning device 90, which includes a body 91 and a sewage tank 92, the sewage tank 92 including a tank body 921, a self-cleaning assembly 923, and a cover body 922; the tank body 921 is configured to enclose an inner cavity 9211 with an opening; the self-cleaning assembly 923 is configured to be detachably mounted on the upper portion of the tank body 921 and is configured to output cleaning liquid to at least clean the inner wall of the tank body 921; the cover body 922 is provided with a gas pipeline 9221 and a gas-liquid separation assembly 9222; the cover body 922 is detachably mounted on the opening of the tank body 921 and is located in the dismounting path of the self-cleaning assembly 923. It can be understood that the cleaning device 90 of the present disclosure can clean the work surface such as the ground and the carpet, and the cleaning device 90 and the cleaning base station 10 can be mutually docked so that the cleaning device 90 discharges sewage into the cleaning base station 10, and the cleaning base station 10 can also charge the cleaning device 90, supplement the cleaning liquid, and the like, which will not be described here. The cleaning device 90 can also include a cleaning liquid tank, a floor brush assembly 94, and a fan unit 96. The cleaning liquid tank is used to provide cleaning liquid to the cleaning member or also can provide cleaning liquid to the self-cleaning assembly 923. The floor brush assembly 94 is arranged at the bottom end of the body 91 and is used to clean the work surface such as the ground, the carpet, or the surface of furniture; a rotating shaft can be arranged between the floor brush assembly 94 and the body 91, and the floor brush assembly 94 can rotate relative to the body 91 through the rotating shaft, so that the user can drag the cleaning device 90 back and forth to clean the work surface. When cleaning the work surface, the floor brush assembly 94 is always attached to the work surface, and the floor brush assembly 94 can include a floor brush housing and a cleaning member rotatably connected to the floor brush housing; the cleaning member can rotate relative to the work surface to wipe the stains on the work surface, and the cleaning member can be a roller brush. As shown, a sewage suction pipeline is arranged in the part of the body 91 connected with the floor brush assembly 94, the bottom end of the sewage suction pipeline is in communication with a sewage suction port arranged at the floor brush assembly 94, and the sewage suction pipeline is in communication with the inner cavity 9211 of the sewage tank 92. The fan unit 96 is used to form negative pressure in the sewage tank 92, so that the dirt on the work surface is sucked into the sewage tank 92. The gas-liquid separation assembly 9222 can isolate the gas outlet and the liquid inlet in the sewage tank 92, and after the dirt on the work surface enters the sewage tank 92, the liquid will fall to the lower portion of the sewage tank 92 under the action of gravity under the blockage of the gas-liquid separation assembly 9222, and the gas will be sucked out of the sewage tank 92 from the gas outlet on the cover body 922, so that the liquid remains in the tank body 921.

[0329] In this way, in the cleaning device 90 of the present disclosure, the inner cavity 9211 in the barrel 921 can be used to contain dirt, and during operation, the gas pipeline 9221 on the cover 922 of the sewage barrel 92 can be in communication with the fan unit 96, and the fan unit 96 can form a negative pressure in the inner cavity 9211 of the barrel 921, so as to suck the dirt on the working surface into the inner cavity 9211 from the dirt suction pipeline. Since the gas-liquid separation assembly 9222 is arranged on the cover 922, dirt droplets can be prevented from entering the fan unit 96 from the cover 922.

[0330] When the cleaning device 90 of the present disclosure is used in combination with the cleaning base station 10 capable of automatically discharging dirt, the cleaning device 90 of the present disclosure can be placed on the cleaning base station 10, and then the dirt in the sewage barrel 92 is automatically discharged into the cleaning base station 10. After the dirt is discharged, the cleaning base station 10 can provide cleaning liquid to the self-cleaning assembly 923 to at least clean the inner wall of the barrel 921, so as to clean the residual dirt on the inner wall of the sewage barrel 92, without the need for the user to manually clean the inside of the sewage barrel 92, which helps to reduce the user's use burden and greatly improves the user's use experience.

[0331] In addition, since the self-cleaning assembly 923 is detachably installed on the upper part of the barrel 921, and the cover 922 is detachably installed on the opening of the barrel 921 and located in the dismounting path of the self-cleaning assembly 923, when assembling the sewage barrel 92 of the present disclosure, only the self-cleaning assembly 923 needs to be placed on the upper part of the barrel 921, and then the cover 922 is installed on the opening of the barrel 921.

[0332] When there is stubborn dirt in the barrel 921 that is difficult to remove, the user can detach the sewage barrel 92 from the body 91, and then detach the cover 922 and the self-cleaning assembly 923 from the barrel 921 in sequence, and flush the barrel 921, the cover 922 and the self-cleaning assembly 923 respectively to remove the stubborn dirt on the inner cavity 9211 of the sewage barrel 92, so as to realize deep cleaning of each component of the sewage barrel 92, prevent bacteria from breeding in the sewage barrel 92, and effectively avoid hygiene problems.

[0333] In order to control the operation of the cleaning device 90 of the present disclosure, the cleaning base station 10 of the present disclosure can further include a control unit capable of being signal-connected with various components on the cleaning base station 10 of the present disclosure to control the working state thereof.

[0334] As shown in FIG. 26 and FIG. 35, in one embodiment of the present disclosure, the top of the self-cleaning assembly 923 is configured to be adjacent to and abut against the bottom of the cover 922. In the case that the top of the self-cleaning assembly 923 is adjacent to and abut against the bottom of the cover 922, the self-cleaning assembly 923 can be arranged at a higher position in the inner cavity 9211 of the sump 92, so that the self-cleaning assembly 923 can output the cleaning liquid to a higher position of the inner wall of the tub 921, thereby increasing the cleaning area of the cleaning liquid on the inner wall of the tub 921 and avoiding the occurrence of cleaning dead angles as much as possible. Moreover, in the case that the top of the self-cleaning assembly 923 abuts against the bottom of the cover 922, in addition to enabling the self-cleaning assembly 923 to output the cleaning liquid to a higher position of the inner wall of the tub 921, the cover 922 and the tub 921 can also jointly fix the self-cleaning assembly 923, so as to prevent the self-cleaning assembly 923 from shaking up and down in the sump 92 during use of the cleaning device 90 of the present disclosure.

[0335] However, in another embodiment of the present disclosure, due to mechanical or manufacturing tolerances and the like, the top of the self-cleaning assembly 923 cannot completely abut against the bottom of the cover 922, but has a certain gap, which can be understood by those skilled in the art. That is, the top of the self-cleaning assembly 923 is adjacent to the bottom of the cover 922, and the gap between the top of the self-cleaning assembly 923 and the bottom of the cover 922 is less than a predetermined threshold. In this way, the self-cleaning assembly 923 can also be arranged at a higher position in the inner cavity 9211 of the sump 92, so that the self-cleaning assembly 923 can output the cleaning liquid to a higher position of the inner wall of the tub 921, thereby increasing the cleaning area of the cleaning liquid on the inner wall of the tub 921 and avoiding the occurrence of cleaning dead angles as much as possible.

[0336] Specifically, as shown in FIG. 28 to FIG. 32, in one embodiment of the present disclosure, the self-cleaning assembly 923 comprises a component body 9231 provided with a flow guide channel 92311, and at least two first nozzles 9232 arranged on the component body 9231 and in communication with the flow guide channel 92311; the at least two first nozzles 9232 are configured to be sequentially and spacedly distributed along the circumference of the component body 9231, and are configured to spray the cleaning liquid at least to the inner wall of the tub 921.

[0337] In this way, during the operation of the self-cleaning assembly 923 of the present disclosure, the flow guide channel 92311 in the component body 9231 can provide the cleaning liquid to each first nozzle 9232, and the at least two first nozzles 9232 sequentially and spacedly distributed along the circumference of the component body 9231 can spray the cleaning liquid to each part of the circumference of the inner wall of the tub 921, thereby cleaning each part of the circumference of the inner wall of the tub 921.

[0338] Specifically, as shown in FIG. 28 and FIG. 32, in one embodiment of the present disclosure, the first nozzle 9232 has a spray channel 92321, which forms a spray opening 92322 at its free end; the cleaning liquid is configured to flow out of the spray opening 92322 along the central axis of the spray channel 92321; wherein the central axis of the spray channel 92321 is configured to form an angle of 40° to 50° with the central axis of the tub 921.

[0339] In the working process of the self-cleaning assembly 923 of the present disclosure, the cleaning liquid flows out of the spray opening 92322 along the central axis of the spray channel 92321 to the inner wall of the tub 921. Since the central axis of the spray channel 92321 forms an angle of 40° to 50° with the central axis of the tub 921, i.e. in the vertical plane, the angle between the flow direction of the cleaning liquid and the inner wall of the tub 921 is suitable, which can ensure that the cleaning liquid can cover most of the area in the height direction of the inner wall of the tub 921, and the cleaning liquid does not lose too much kinetic energy when flowing onto the inner wall of the tub 921. The cleaning liquid still has a lot of kinetic energy during the process of flowing down along the inner wall of the tub 921, so as to effectively improve the cleaning effect of the cleaning liquid on the inner wall of the tub 921, and facilitate the cleaning liquid to remove stubborn stains on the inner wall of the tub 921.

[0340] In one specific embodiment of the present disclosure, the central axis of the spray channel 92321 is configured to form an angle of 45° with the central axis of the tub 921, thereby effectively improving the cleaning effect of the cleaning liquid on the inner wall of the tub 921.

[0341] Further, as shown in FIG. 30 and FIG. 31, in one embodiment of the present disclosure, the intersection of the central axis of the spray channel 92321 and the inner wall of the inner cavity 9211 is marked as point A, the normal projection of the central axis B of the spray channel 92321 on the cross section of the tub 921, and the tangent line C at the position of point A on the tub 921 form an angle of 40° to 50°.

[0342] In the working process of the self-cleaning assembly 923 of the present disclosure, the cleaning liquid flows out from the nozzle 92322 along the central axis of the spray flow channel 92321 to the inner wall in the tub 921. The intersection of the central axis of the spray flow channel 92321 and the inner wall of the inner cavity 9211 is marked as point A. When the angle between the normal projection of the central axis of the spray flow channel 92321 on the cross section of the tub 921 and the tangent line at the position of point A on the tub 921 is 40° to 50°, that is, in the horizontal plane, the angle between the flow direction of the cleaning liquid and the inner wall of the tub 921 is also relatively appropriate. When the cleaning liquid flows onto the inner wall of the tub 921, it will not lose too much kinetic energy, and it can continue to rotate along the inner wall of the tub 921 during the downward flow along the inner wall of the tub 921, thereby increasing the area of the corresponding cleaning area of each first nozzle 9232, reducing the cleaning dead angle, and improving the cleaning effect. In an embodiment of the present disclosure, the intersection of the central axis of each spray flow channel 92321 on the inner wall of the inner cavity 9211 is configured to be located on the same cross section of the tub 921. Since the intersection of the central axis of each spray flow channel 92321 on the inner wall of the inner cavity 9211 is located on the same cross section of the tub 921, the cleaning liquid sprayed by each first nozzle 9232 can be sprayed to the same height of the inner wall of the inner cavity 9211, thereby forming a uniform water curtain of cleaning liquid on the inner wall of the inner cavity 9211. The kinetic energy of the cleaning liquid sprayed by each first nozzle 9232 can be uniformly superimposed on the inner wall of the tub 921, thereby maximizing the use of the kinetic energy of the cleaning liquid and improving the cleaning effect. This avoids the situation that the height of the cleaning liquid sprayed by some of the first nozzles 9232 is inconsistent, causing the flow rate of the cleaning liquid in some areas of the inner wall of the tub 921 to be inconsistent, and the kinetic energy of the cleaning liquid being easily lost when superimposed. The cleaning liquid at the lower part of the inner wall of the tub 921 becomes a relatively weak water flow, and the cleaning effect is poor.

[0343] As shown in FIG. 31, in an embodiment of the present disclosure, the central axis of each spray flow channel 92321 is configured to extend obliquely in the same deflection direction in the circumferential direction of the tub 921. Here, the same deflection direction refers to the oblique direction of the central axis of each spray flow channel 92321 corresponding to the arrangement direction thereof. For example, when a plurality of spray flow channels 92321 are arranged in a ring shape, the central axis of each spray flow channel 92321 can be inclined in the clockwise direction or the counterclockwise direction of the ring. Further, the central axis of each spray flow channel 92321 extends obliquely in the same deflection direction with the same deflection angle. As shown in FIG. 31, it can be understood that the central axis of each spray flow channel 92321 can be inclined in the clockwise direction in the circumferential direction of the tub 921; or the central axis of each spray flow channel 92321 can be inclined in the counterclockwise direction in the circumferential direction of the tub 921, which is not limited herein.

[0344] Since the central axis of each ejection channel 92321 extends along the same deflection direction and is inclined in the circumferential direction of the barrel 921, the cleaning liquid sprayed by each first nozzle 9232 can form a spiral cleaning liquid curtain on the inner wall of the barrel 921, so that the cleaning liquid sprayed by each first nozzle 9232 can cover the circumferential direction of the inner wall of the barrel 921, and avoid the occurrence of cleaning dead angles in the circumferential direction of the inner wall of the barrel 921.

[0345] As shown in FIG. 32, in an embodiment of the present disclosure, the end face where the nozzle 92322 is located is configured to be perpendicular to the central axis of the ejection channel 92321, and the end face where the nozzle 92322 is located is configured to have an included angle with the cross section of the barrel 921. This makes the end face where the nozzle 92322 is located be inclined, and the inclined face faces the inner wall of the inner cavity 9211. Since the end face where the nozzle 92322 is located is perpendicular to the central axis of the ejection channel 92321, it can be ensured that the cleaning liquid is uniformly sprayed from the nozzle 92322 along the ejection channel 92321, the cleaning liquid is not easily disturbed at the nozzle 92322, the flow direction does not change, and the kinetic energy loss of the cleaning liquid flowing through the ejection channel 92321 is also small. The end face where the nozzle 92322 is located has an included angle with the cross section of the barrel 921, and the inclined face of the nozzle 92322 faces the wall of the barrel 921, which facilitates the cleaning liquid to flow onto the inner wall of the barrel 921 at an angle to reduce the kinetic energy loss of the cleaning liquid on the inner wall of the barrel 921.

[0346] Further, as shown in FIG. 32, in an embodiment of the present disclosure, the first nozzle 9232 includes a nozzle body 92323 having a liquid channel, the nozzle body 92323 is configured to extend in the central axis direction of the barrel 921, and the ejection channel 92321 is configured to communicate with the liquid channel of the nozzle body 92323. In this way, during the working process of the self-cleaning assembly 923 of the present disclosure, the flow guide channel 92311 in the component body 9231 can provide cleaning liquid to the nozzle body 92323 of each first nozzle 9232, the cleaning liquid can flow along the liquid channel of the nozzle body 92323 to the ejection channel 92321, and be sprayed from the nozzle 92322. Since the nozzle body 92323 of each first nozzle 9232 extends in the central axis direction of the barrel 921, the first nozzle 9232 can be conveniently installed and arranged, and after the self-cleaning assembly 923 is installed in the barrel 921, the first nozzle 9232 can also be as close as possible to the inner wall of the barrel 921 to reduce the kinetic energy loss of the cleaning liquid during the process of being sprayed from the nozzle 92322 to the inner wall of the barrel 921.

[0347] As shown in FIG. 26 and FIG. 28, in one embodiment of the present disclosure, a pipe joint 9213 for interfacing with the machine body 91 is arranged on the side of the barrel body 921 facing the machine body 91, and a first interface 9214 in the inner cavity 9211 of the barrel body 921 and in communication with the pipe joint 9213; a second interface 9234 extending downward and in communication with the flow guide channel 92311 is arranged on the component body 9231, and the first interface 9214 is configured to connect and conduct with the second interface 9234. In this way, during the installation of the sewage barrel 92 of the present disclosure, the pipe joint 9213 on the outside of the barrel body 921 can be interfaced with the water injection head in the installation slot of the machine body 91, and during the operation of the self-cleaning assembly 923, the machine body 91 can provide cleaning liquid to the flow guide channel 92311 of the self-cleaning assembly 923 through the pipe joint 9213, the first interface 9214 and the second interface 9234. Moreover, the second interface 9234 can cooperate with the first interface 9214 to position the bottom of the component body 9231, and the top of the cover body 922 after installation forms the top positioning of the component body 9231, ensuring that the self-cleaning assembly 923 can be positioned at a predetermined position.

[0348] Further, in one embodiment of the present disclosure, the pipe joint 9213 and the top end face of the cover body 922 are both configured to extend downwardly and obliquely, the pipe joint 9213 and the top end face of the cover body 922 have the same oblique direction, and the angle of the oblique pipe joint 9213 is greater than or equal to the angle of the oblique top end face of the cover body 922. Because the pipe joint 9213 and the top end face of the cover body 922 both extend downwardly and obliquely, and have the same oblique direction, during the installation of the sewage barrel 92 of the present disclosure, the sewage barrel 92 can be first placed at the bottom of the installation slot of the machine body 91, and then turned upward to push the sewage barrel 92, the pipe joint 9213 is interfaced with the water injection head in the installation slot of the machine body 91, and the top end face of the cover body 922 is interfaced with the fan unit 96 to complete the installation of the sewage barrel 92. Because the angle of the oblique pipe joint 9213 is greater than or equal to the angle of the oblique top end face of the cover body 922, the pipe joint 9213 can be first interfaced with the water injection head in the installation slot of the machine body 91, and the top end face of the cover body 922 can be then interfaced with the fan unit 96, so that the installation of the sewage barrel 92 is more convenient and the problem of poor interfacing between the pipe joint 9213 and the water injection head in the installation slot of the machine body 91 is prevented.

[0349] As shown in FIG. 25, in one embodiment of the present disclosure, the dirty inlet pipe 9212 is arranged on the barrel 921, and the dirty inlet pipe 9212 has a transverse portion 92312 extending in a transverse direction above the barrel 921. Since the dirty inlet pipe 9212 is arranged on the barrel 921, and the dirty inlet pipe 9212 has the transverse portion 92312 extending in a transverse direction above the barrel 921, it is convenient for the dirt to enter the inner cavity 9211 of the sewage tank 92 along the dirty inlet pipe 9212.

[0350] Further, as shown in FIG. 28, in one embodiment of the present disclosure, the component body 9231 is configured in a ring structure extending circumferentially along the barrel 921, and the component body 9231 is provided with a recessed portion 92313 for avoiding at the position of the transverse portion 92312; the first nozzle 9232 is arranged at the bottom of the component body 9231, so that the recessed portion 92313 for avoiding arranged at the position of the transverse portion 92312 of the component body 9231 does not affect the overall arrangement of the dirty inlet pipe 9212, and the component body 9231 configured in a ring structure extending circumferentially along the barrel 921 also does not affect the overall structural strength of the component body 9231, while the first nozzle 9232 arranged at the bottom of the component body 9231 can effectively reduce the cleaning dead angle of the inner wall of the barrel 921.

[0351] Further, as shown in FIG. 28, in one embodiment of the present disclosure, the component body 9231 is provided with a positioning portion 9235 extending downward; the inner cavity 9211 of the barrel 921 is provided with a cooperating portion 9215 cooperating with the positioning portion 9235; wherein the positioning portion 9235 and the second abutting portion 9234 are configured to be located on both sides of the transverse portion 92312. In this way, the positioning portion 9235 on the component body 9231 and the cooperating portion 9215 on the inner cavity 9211 of the barrel 921 can cooperate with each other, and the second abutting portion 9234 cooperates with the first abutting portion 9214, which can further realize the positioning of the component body 9231 from both sides of the transverse portion 92312, so as to ensure that the self-cleaning assembly 923 can be installed at the predetermined position.

[0352] In one embodiment of the present disclosure, at least two second nozzles 9233 are arranged on the component body 9231 and communicate with the flow guide channel 92311, and the at least two second nozzles 9233 are configured to at least spray the cleaning liquid to the gas-liquid separation assembly 9222. In this way, in the working process of the self-cleaning assembly 923 of the present disclosure, the flow guide channel 92311 can provide cleaning liquid to each second nozzle 9233, and the at least two second nozzles 9233 can at least spray cleaning liquid to the gas-liquid separation assembly 9222, so as to clean the gas-liquid separation assembly 9222.

[0353] Specifically, as shown in FIG. 28, in one embodiment of the present disclosure, the component body 9231 is configured in a ring structure extending circumferentially along the barrel 921, and the at least two second nozzles 9233 are configured to be spaced apart on the inner circumferential wall of the component body 9231. Since the at least two second nozzles 9233 are spaced apart on the inner circumferential wall of the component body 9231, the at least two second nozzles 9233 spaced apart on the inner circumferential wall of the component body 9231 can spray cleaning liquid to each part of the circumference of the gas-liquid separation assembly 9222, thereby cleaning each part of the circumference of the gas-liquid separation assembly 9222.

[0354] As shown in FIG. 28 and FIG. 33, in one embodiment of the present disclosure, the X-axis and Y-axis are defined in the same plane and perpendicular to each other, wherein the X-axis direction is the front-rear direction of the cleaning equipment 90; the component body 9231 is provided with a flow partition plate 92314 extending downward, and the two sides of the flow partition plate 92314 are configured to extend to the corresponding inner wall of the barrel 921 in the Y-axis direction. The two sides of the flow partition plate 92314 extend to the corresponding inner wall of the barrel 921 on both sides, so that the two sides of the flow partition plate 92314 can form a seal with the corresponding inner wall of the barrel 921. When the user uses the cleaning equipment 90 of the present disclosure, when the machine body 91 as a whole is inclined to the rear side of the user or even lies flat, the flow partition plate 92314 can isolate the upper rear side of the inner cavity 9211 of the sewage barrel 92 from the upper front side of the inner cavity 9211 where the gas outlet is located. When there is a lot of dirt, the user pushes and pulls the cleaning equipment 90, even if the dirt repeatedly shakes, it will be blocked by the flow partition plate 92314, thereby avoiding the situation that the dirt droplets enter the fan unit 96 through the gas outlet, causing damage to the fan unit 96. At the same time, the flow partition plate 92314 is arranged on the component body 9231, and when the component body 9231 is disassembled, the flow partition plate 92314 can be synchronously disassembled with the component body 9231. Preferably, the flow partition plate 92314 is arc-shaped, and the distance between the two sides of the flow partition plate 92314 abutting against the inner wall of the barrel 921 from the machine body 91 is less than the distance between the middle position of the flow partition plate 92314 from the machine body 91. In this way, when the machine body 91 is rotated to the lying position, the end of the barrel 921 away from the machine body 91 is located below, and the end of the barrel 921 towards the machine body 91 is located above, the space below the two sides of the flow partition plate 92314 abutting against the inner wall of the barrel 921 is greater than the space below the middle position of the flow partition plate 92314, and when the machine body 91 is pulled back to drag the cleaning, the larger space on both sides is beneficial to reduce the inrush current.

[0355] Further, as shown in FIG. 33, in another embodiment of the present disclosure, the gas-liquid separation assembly 9222 includes a baffle plate 9223 extending downward from the cover 922, and the baffle plates 92314 on the component body 9231 are provided with two baffle plates 92314 respectively located on opposite sides of the baffle plate 9223; the baffle plates 92314 are configured to extend from the position of the baffle plate 9223 to the inner wall corresponding to the barrel 921 in the Y-axis direction. Since the gas-liquid separation assembly 9222 includes the baffle plate 9223 extending downward from the cover 922, and the baffle plates 92314 are respectively located on opposite sides of the baffle plate 9223 and extend from the position of the baffle plate 9223 to the inner wall corresponding to the barrel 921 in the Y-axis direction, it can be ensured that the baffle plate 9223 and the baffle plates 92314 form an integral baffle member in the Y-axis direction, thereby isolating the rear side of the upper portion of the inner cavity 9211 of the sewage tank 92 from the front side of the upper portion of the inner cavity 9211 where the gas outlet and the dirty inlet are located, which can prevent dirty droplets from entering the fan unit 96 through the gas outlet, causing damage to the fan unit 96, and can also ensure that the dirt flows along the baffle plate 9223 to the inner cavity 9211 of the sewage tank 92.
