Description

Technical Field

[0001] The present application relates to the technical field of cleaning devices, and in particular to a sewage collection mechanism, cleaning equipment and a base station. Background Art

[0002] At present, cleaning equipment such as floor scrubbers and floor mops are usually used to clean garbage and stains on the floor or desktop. The sewage generated by the floor brushes of some cleaning equipment (such as floor mops) during the cleaning process will be sucked into the sewage tank (also called a sewage bucket) on the cleaning equipment. After the cleaning equipment returns to the base station, the sewage will be recycled into the sewage tank of the base station. Since there will be a lot of stains and garbage in the sewage, after the sewage enters the sewage tank, the stains and garbage in the sewage are easy to stick to the inner wall of the sewage tank. When the stains and garbage accumulate, the sewage tank needs to be removed from the cleaning equipment or base station for cleaning, which makes the cleaning of the sewage tank very troublesome and inconvenient to operate.

[0047] Since the sewage tank 10 of the existing cleaning equipment 01 or base station 02 usually needs to be removed for manual cleaning, the cleaning of the sewage tank 10 is very troublesome and inconvenient. In order to solve the above problems, the first embodiment of the present invention provides a sewage collection mechanism. Figures 1 to 14 The sewage collection mechanism includes a sewage tank 10 and a suction member 20. The sewage tank 10 is provided with a receiving chamber 101, a tangential water inlet 102 and an air extraction port 103. The tangential water inlet 102 is an inlet opened on the outer peripheral wall of the sewage tank 10 along the tangential direction of the inner wall surface of the receiving chamber 101. Therefore, when sewage enters the receiving chamber 101 through the tangential water inlet 102, it will enter the receiving chamber 101 along the tangential direction of the inner wall surface of the receiving chamber 101. The air extraction port 103 is provided on the sewage tank 10 along the first direction (the first direction is Figure 5 The tangential water inlet 102 is located on a side of the sewage tank 10 near the air extraction port 103 and is in communication with the accommodating chamber 101. Specifically, the tangential water inlet 102 is located on the outer peripheral wall of the sewage tank 10 near the top thereof. After the sewage enters the accommodating chamber 101 through the tangential water inlet 102, the sewage, under the action of the suction member 20, generates centrifugal force to flow in a spiral from the top of the accommodating chamber 101 near the air extraction port 103 toward the bottom of the accommodating chamber 101. This spiral flow of sewage can flush and clean various portions of the inner wall of the accommodating chamber 101.

[0048] The suction member 20 is mounted on one side of the sewage tank 10 and communicates with the air inlet 103. The suction member 20 is used to apply negative pressure to the receiving chamber 101 through the air inlet 103, causing sewage to enter the tangential water inlet 102 and then flow spirally along the inner wall of the receiving chamber 101. The flow force or flushing force generated by the spiral flow of sewage can flush away dirt and debris from the inner wall of the receiving chamber 101, thereby achieving a self-cleaning operation of the sewage tank 10. In other words, while the sewage tank 10 of this embodiment collects sewage visually under the negative pressure of the suction member 20, it can also spirally enter the receiving chamber 101 through the tangential water inlet 102 provided on the sewage tank 10 and clean the inner wall of the receiving chamber 101. This allows the sewage tank 10 to self-clean without the need for an additional power source, making the cleaning operation convenient and energy-efficient.

[0049] As can be seen, in this embodiment, the sewage tank 10 of the sewage collection mechanism is provided with a tangential water inlet 102, which is located on the side of the sewage tank 10 near the air extraction port 103 and is connected to the receiving chamber 101. When the sewage to be sucked in enters the receiving chamber 101 tangentially along the tangential water inlet 102 under the suction action of the suction member 20, the sewage generates a centrifugal force and, under the action of the centrifugal force, flows spirally from top to bottom along the inner wall of the receiving chamber 101 into the receiving chamber 101. During this process, the flow force or flushing force generated by the spirally flowing sewage on the inner wall of the receiving chamber 101 can remove stains, garbage, etc. on the inner wall of the receiving chamber 101, achieving the purpose of cyclonic flushing self-cleaning of the receiving chamber 101 of the sewage tank 10, eliminating the need for users to frequently clean the sewage tank 10, thereby improving the cleaning convenience of the sewage tank 10.

[0050] In order to make the sewage have a better cleaning effect on the inner wall surface of the accommodating chamber 101, Figure 7 and Figure 8 As shown, a diversion channel 104 is also provided in the sewage tank 10 in this embodiment. The diversion channel 104 is recessed in the inner wall surface of the accommodating chamber 101 and is connected to the tangential water inlet 102, and the diversion channel 104 extends along the circumference of the outer peripheral wall of the sewage tank 10. The diversion channel 104 can divert the sewage entering the accommodating chamber 101 from the tangential water inlet 102 along the circumference of the outer peripheral wall of the sewage tank 10 to a position of the accommodating chamber 101 away from the tangential water inlet 102, thereby increasing the contact area between the sewage and the inner wall surface of the accommodating chamber 101 when the sewage flows in a spiral shape, thereby improving the cleaning coverage and cleaning efficiency of the accommodating chamber 101. The diversion channel 104 can also help the sewage form a more uniform and stable vortex, thereby improving the cleaning strength and cleaning effect of the spirally flowing sewage on the accommodating chamber 101.

[0051] In this embodiment, the diversion channel 104 has a longitudinal section along a first direction, and the area of the longitudinal section gradually decreases in the direction away from the tangential water inlet 102. In other words, the area of the longitudinal section of the diversion channel 104 on the side away from the tangential water inlet 102 is smaller than the area on the side close to the tangential water inlet 102. After a certain flow rate of sewage enters the diversion channel 104 from the tangential water inlet 102, the flow rate of the sewage will gradually increase under the action of the diversion channel 104 (this is because when passing through the smaller longitudinal section of the diversion channel 104 in the same time, the sewage of a predetermined flow rate must flow at a faster speed to maintain the same volume flow rate). During the spiral flow of the sewage after the flow rate has increased, the cleaning force on the inner wall surface of the accommodating chamber 101 will be increased, so that the sewage has a better cleaning effect on the accommodating chamber 101.

[0052] Among them, the depression depth of the diversion channel 104 gradually decreases in the direction away from the tangential water inlet 102. The depression depth and the depth of the diversion channel 104 radially depressed along the accommodating chamber 101. The gradual decrease in the depression depth not only has a positive effect on increasing the flow rate of sewage, but also ensures that the sewage can flow smoothly to the inner wall surface of the accommodating chamber 101, reducing the kinetic energy loss generated when the sewage passes through the diversion channel 104. Preferably, the side of the diversion channel 104 away from the tangential water inlet 102 is flush with the inner wall surface of the accommodating chamber 101 (that is, the depression depth of the diversion channel 104 here is equivalent to zero), thereby enabling the diversion channel 104 to divert the mainstream water column of the sewage to the inner wall surface of the accommodating chamber 101 more smoothly, so that the sewage flows in a spiral shape at high speed, thereby improving the cleaning effect of the accommodating chamber 101.

[0053] The diversion channel 104 in this embodiment is an arc-shaped channel structure, and both the longitudinal section and the cross section of the arc-shaped channel structure are arc-shaped. The arc-shaped channel structure can reduce the flow resistance of the diversion channel 104 to the sewage, thereby improving the cleaning effect of the sewage on the accommodating chamber 101. A chamfered corner 1041 is provided between the diversion channel 104 and the inner wall surface of the accommodating chamber 101, and the chamfered corner 1041 is located at least on the side of the diversion channel 104 close to the bottom of the accommodating chamber 101 along the first direction. Providing the chamfered corner 1041 on the side of the diversion channel 104 close to the bottom of the accommodating chamber 101 along the first direction can further reduce the resistance encountered by the sewage during the flow process, which has a positive effect on improving the cleaning effect of the sewage on the accommodating chamber 101.

[0054] See Figures 3 to 7 The sewage tank 10 in this embodiment includes a box body 11 and a box cover 12. A receiving tank 110 is provided in the box body 11. The inner wall surface of the receiving tank 110 is a cylindrical surface. The tangential water inlet 102 is provided on the side wall of the box body 11 along the tangent direction of the inner wall surface of the receiving tank 110 and is connected to the receiving tank 110. The diversion channel 104 is provided on the inner wall surface of the receiving tank 110. When the inner wall surface of the receiving tank 110 is a cylindrical surface, the sewage will encounter less resistance during its spiral flow, which will increase the cleaning force of the sewage on the inner wall surface of the receiving tank 110, so that the stains and garbage on the inner wall surface can be quickly washed away by the sewage, thereby making the self-cleaning effect of the sewage tank 10 better. The box cover 12 is buckled onto the receiving tank 110 and is surrounded by the inner wall surface of the receiving tank 110 to form a receiving cavity 101. The sewage tank 10, consisting of the tank body 11 and the tank cover 12, is not only easy to install, but also facilitates the processing of the tangential water inlet 102 and the diversion channel 104. In this embodiment, the tangential water inlet 102 and the diversion channel 104 are first processed on the tank body 11 before the tank cover 12 and the tank body 11 are fastened together. This improves the processing convenience of the tangential water inlet 102 and the diversion channel 104 and reduces the processing difficulty.

[0055] See Figures 8 to 10In order to further reduce the difficulty of processing the tangential water inlet 102, the box body 11 in this embodiment includes a first column section 111 and a second column section 112. The first column section 111 is provided with a first groove 1111 and a water pipe 1112. The first groove 1111 is recessed in the first direction in the first column section 111. The water pipe 1112 is located on the outer side of the first column section 111. Along the tangential direction of the inner wall of the first groove 1111, the water pipe 1112 is connected to the side of the first groove 1111 close to the box cover 12 and forms the tangential water inlet 102 at the connection point. The second column section 112 is connected between the first column section 111 and the box cover 12 and covers the pipe opening of the water pipe 1112 close to the box cover 12, so that sewage can enter the tangential water inlet 102. The second column segment 112 is provided with a through hole 1121 extending along the first direction. The through hole 1121 is connected to the first groove 1111 and forms a receiving groove 110 with the first groove 1111. In this embodiment, the housing 11 is composed of the first column segment 111 and the second column segment 112. By connecting the water pipe 1112 on the first column segment 111 tangentially to the first groove 1111, a tangential water inlet 102 is formed, which reduces the manufacturing difficulty. The sewage tank 10 is then assembled by connecting the second column segment 112 between the first column segment 111 and the lid 12, achieving efficient and convenient assembly.

[0056] The water supply pipe 1112 in this embodiment can be connected to the sewage suction pipe of the cleaning device 01, so that the sewage generated by the cleaning components of the cleaning device 01 during cleaning of floors, countertops, walls, etc. can flow through the sewage suction pipe and enter the holding tank 110 from the water supply pipe 1112. The water supply pipe 1112 can be laid in a curved shape on the outer side of the first column segment 111. However, this may create significant resistance to the sewage entering the holding tank 110, which would reduce the centrifugal force generated by the sewage entering the holding tank 110. To ensure that the centrifugal force generated by the sewage entering the holding tank 110 is greater, the water supply pipe 1112 in this embodiment is laid straight along the first direction on the outer side of the first column segment 111, thereby reducing the resistance encountered by the sewage before entering the holding tank 110.

[0057] To further reduce the difficulty of processing the guide channel 104. Figure 9 As shown, the first column segment 111 of this embodiment is further provided with a second groove 1113. Along the radial direction of the receiving groove 110, the second groove 1113 is recessed in the inner wall surface of the first groove 1111, and the second groove 1113 is located in the first groove 1111 near the notch of the second column segment 112 and is connected to the tangential water inlet 102. When the second groove 1113 is recessed in the inner wall surface of the first groove 1111, the groove wall of the second groove 1113 along the radial direction of the receiving groove 110 can protrude from the outer side surface of the first column segment 111 (as shown in FIG. Figure 9In the structure shown in FIG, when the outer peripheral wall of the first groove 1111 is thicker, the groove wall of the second groove 1113 along the radial direction of the accommodating groove 110 may not be set to protrude from the outer side surface of the first column segment 111. The specific concave form of the second groove 1113 may be determined according to the actual situation and is not limited to the present embodiment. Figure 10 As shown, along the radial direction of the receiving groove 110, the inner wall surface of the through hole 1121 near the first cylindrical section 111 is recessed with a third groove 1122. The inner wall surface of the third groove 1122 covers the pipe opening of the water delivery pipe 1112 and the second groove 1113, and together with the second groove 1113, forms a diversion channel 104. Specifically, the third groove 1122 and the second groove 1113 are mirror images of each other, so that when the third groove 1122 and the second groove 1113 are engaged with each other through the groove walls, they not only do not block the tangential water inlet 102, but also form a diversion channel 104.

[0058] Therefore, in this embodiment, by setting the second groove 1113 on the first column segment 111 and the third groove 1122 on the second column segment 112, the second groove 1113 and the third groove 1122 are set correspondingly and the first column segment 111 and the second column segment 112 are connected together to obtain the guide channel 104, thereby improving the processing convenience of the guide channel 104.

[0059] In order to make the assembly between the first column segment 111 and the second column segment 112 more efficient and convenient. Figure 6 and Figures 9 and 10 As shown, this embodiment further comprises a snap-fit structure 113 between the first column segment 111 and the second column segment 112. The snap-fit structure comprises a snap-fit groove 131 and a snap-fit flange 132. The snap-fit groove 131 is provided on at least one of the first column segment 111 and the second column segment 112, while the snap-fit flange 132 is provided on at least the other of the first column segment 111 and the second column segment 112. Thus, when assembling the first column segment 111 and the second column segment 112, it is sufficient to ensure that the snap-fit flange 132 snaps into the snap-fit groove 131. This makes assembly efficient and convenient, and reduces the risk of assembly deviation, significantly improving the assembly accuracy between the first column segment 111 and the second column segment 112.

[0060] Specifically, if Figure 9 and Figure 10As shown, in this embodiment, the engaging flange 132 is projected from the outer circumferential wall of the second column segment 112, near the end of the first column segment 111, and extends along the outer contours of the through-hole 1121 and the third groove 1122. The engaging groove 131 is recessed into the outer circumferential wall of the first column segment 111, near the end of the second column segment 112, and extends along the outer contours of the first groove 1111 and the second groove 1113. When assembling the first and second column segments 111, 112, the engaging flange 132 is simply engaged with the engaging groove 131, achieving precise and efficient assembly while also ensuring the sealing of the receiving groove.

[0061] The air extraction port 103 in this embodiment is located on the side of the box cover 12 away from the box body 11. After the sewage enters the accommodating chamber 101 along the tangential water inlet 102, it is mixed with a large amount of airflow. If the garbage in the sewage enters the corresponding suction device or suction pipe with the airflow, it will cause the suction device, pipe and other equipment to be blocked or even damaged. Figure 5 As shown, the sewage collection mechanism provided in this embodiment also includes a water-gas separation assembly 30. The water-gas separation assembly 30 is mounted on the housing cover 12 and located between the tangential water inlet 102 and the air extraction port 103. The water-gas separation assembly 30 is used to separate the sewage from the airflow and discharge the airflow through the air extraction port 103 to the suction member 20. After the sewage enters the accommodating chamber 101 through the tangential water inlet 102, the water-gas separation assembly 30 separates the sewage from the airflow and discharges the airflow through the air extraction port 103 to the suction member 20, which then removes the airflow, thereby improving the structural stability and reliability of the sewage collection mechanism.

[0062] A connecting hole is provided in the box cover 12, which connects the accommodating chamber 101 and the air extraction port 103. To improve the water vapor separation effect of the water vapor separation component 30, the water vapor separation component 30 in this embodiment includes a driving member 31 and a separation impeller 32. The driving member 31 is installed on the side of the box cover 12 close to the box body 11. The driving member 31 includes a first output shaft 310, which is rotatable around its own axis. The separation impeller 32 is connected to the first output shaft 310. The separation impeller 32 is provided with a ventilation gap 320 connected to the connecting hole, and at least a portion of the separation impeller 32 along the first direction is arranged opposite to the tangential water inlet 102. The driving member 31 is capable of driving the first output shaft 310 to rotate the separation impeller 32. During rotation, the separation impeller 32 separates the sewage and waste in the sewage from the airflow. The sewage and waste in the sewage enter the receiving chamber 101 for temporary storage. The airflow flows along the ventilation gap 320 of the separation impeller 32 to the communication hole, then flows from the communication hole along the air outlet 103 to the suction member 20, where it is discharged. Because at least a portion of the separation impeller 32 along the first direction is disposed opposite the tangential water inlet 102, when sewage enters the receiving chamber 101 through the tangential water inlet 102, the sewage and airflow are quickly and promptly separated by the separation impeller 32. The separated airflow then flows out of the receiving chamber 101 along the ventilation gap 320 of the separation impeller 32, resulting in efficient and timely water-gas separation.

[0063] The drive member 31 in this embodiment can be a combination of a motor and a transmission component, or it can be a single motor. When the motor and transmission component are combined, the transmission component is connected between the motor and the first output shaft 310. In this case, the transmission component may specifically include a pulley, a transmission belt, and other structures. Pulleys are mounted on the motor's rotating shaft and the first output shaft 310, and the transmission belt is mounted on the pulleys on the motor and the first output shaft 310. When the motor starts, the pulleys and transmission belt drive the first output shaft 310 to rotate. However, this method is relatively complex and will occupy a larger installation space of the tank cover 12. Therefore, the drive member 31 in this embodiment is preferably a motor. The motor directly drives the first output shaft 310 to rotate the separation impeller 32 to perform the water-gas separation operation. This makes the structure of the water-gas separation component 30 more concise and easy to assemble, saves installation space of the tank cover 12, and improves the compactness and reliability of the overall structure of the sewage tank 10.

[0064] The separation impeller 32 in this embodiment is specifically a columnar hollow structure. Figure 8As shown, a first mounting groove 321 is provided on the side of the separation impeller 32 close to the driving member 31. The outer peripheral wall and the bottom of the first mounting groove 321 are both provided with ventilation gaps 320 connected to the first mounting groove 321, and the portion between two adjacent ventilation gaps 320 constitutes the blades of the separation impeller 32. The first mounting groove 321 connects the ventilation gap 320 and the connecting hole, so that the air flow can enter the first mounting groove 321 from the ventilation gap 320 and then be discharged from the connecting hole to the air outlet 103. The first output shaft 310 is connected to the bottom of the first mounting groove 321. When the driving member 31 is started, the first output shaft 310 can be driven to drive the separation impeller 32 to rotate. This assembly method not only reduces the assembly difficulty, but also makes the structural strength of the driving member 31 and the separation impeller 32 better, more stable and reliable after assembly. Preferably, along the radial direction of the receiving tank 110, the projected outer contours of the tangential water inlet 102 and the diversion channel 104 are both located within the projected outer contour of the separation impeller 32, so that the separation impeller 32 can more promptly and effectively separate the sewage and airflow. The side of the separation impeller 32 away from the tank cover 12 can extend to the lower portion of the tangential water inlet 102 near the bottom of the receiving chamber 101, so that the separation impeller 32 can promptly discharge the airflow separated from the spiral flow to the communication hole.

[0065] At the same time, in order to improve the assembly convenience between the water-gas separation component 30 and the box cover 12, please refer to Figure 7 as well as Figures 11 to 13In this embodiment, the box cover 12 includes a main body 121 and a mounting portion 122. The communicating holes include a first communicating hole 1211 and a second communicating hole 1222. The mounting portion 122 is connected between the box body 11 (specifically, the second column section 112 of the box body 11) and the main body 121. The air exhaust port 103 is provided on the side of the main body 121 away from the mounting portion 122. The first communicating hole 1211 is provided through the main body 121 and is connected to the air exhaust port 103. The mounting portion 122 is connected to the main body 121. A second mounting groove 1221 is provided on the side of the mounting portion 122 close to the main body 121. The part of the second mounting groove 1221 away from the main body 121 extends from an end of the mounting portion 122 away from the main body 121. The second communicating hole 1222 is provided through the mounting portion 122 along the first direction, and the second communicating holes 1222 are arranged around the outer periphery of the second mounting groove 1221 and are connected to the first communicating hole 1211 and the accommodating cavity 101. The motor, serving as the driving element 31, is mounted within the second mounting slot 1221, with the first output shaft 310 extending through the bottom of the second mounting slot 1221 and connected to the separation impeller 32. A relief groove 1223 is provided on the side of the mounting portion 122 near the housing 11, adapted to mate with the end of the separation impeller 32 near the mounting portion 122. The relief groove 1223 surrounds the outer periphery of the second connecting hole 1222, with the end of the separation impeller 32 near the mounting portion 122 positioned within the relief groove 1223 and having a clearance fit within the relief groove 1223. This ensures that the ventilation gap 320 of the separation impeller 32 communicates with the second connecting hole 1222 and that the separation impeller 32, driven by the first output shaft 310, can rotate relative to the mounting portion 122.

[0066] As can be seen from the above, this embodiment divides the tank cover 12 into a main body 121 and a mounting portion 122. After the main body 121 is provided with the air extraction port 103 and the first communication hole 1211, the motor is installed in the second mounting groove 1221 of the mounting portion 122 and connected to the separation impeller 32. The mounting portion 122 is then installed between the main body 121 and the housing 11 to assemble the sewage tank 10. This structure of the tank cover 12 in this embodiment not only improves the assembly convenience between the water-gas separation assembly 30 and the tank cover 12, but also makes the structure between the water-gas separation assembly 30 and the tank cover 12 more compact and reliable. The outer peripheral surface of the mounting portion 122 is nested with the housing 11. To improve the assembly seal between the tank cover 12 and the housing 11, this embodiment may also provide a sealing member 123 between the mounting portion 122 and the housing 11. The sealing member 123 seals the assembly gap between the mounting portion 122 and the housing 11. A sealing ring is also provided between the mounting portion 122 and the main body 121 to seal the assembly gap therebetween, thereby improving the sealing of the sewage tank 10 and, in turn, enhancing the suction efficiency of the suction member 20 when applying negative pressure to the sewage tank 10. The sealing member 123 can be, for example, a sealing rubber ring, a sealing silicone ring, or the like.

[0067] In addition, in order to further filter the liquid and garbage in the air flow and prevent the liquid and / or garbage from still existing in the air flow and thus damaging the suction member 20, the sewage tank 10 in this embodiment further includes a filter member 40. At this time, a third mounting groove 1212 is provided on the side of the main body 121 away from the mounting portion 122 in this embodiment, and the air suction port 103 is a groove of the third mounting groove 1212 away from the mounting portion 122. Figure 11 As shown, the first connecting hole 1211 is provided along the first direction through the bottom of the third mounting groove 1212. Figure 5 As shown, the filter element 40 is installed in the third installation groove 1212. Therefore, after the airflow separated by the separation impeller 32 enters the first communication hole 1211 through the second communication hole 1222, it first passes through the filter element 40 to further filter out moisture and garbage in the airflow. The filtered, purer airflow is discharged through the suction element 20 without causing damage to the suction element 20, thereby extending the service life of the sewage collection mechanism.

[0068] The filter element 40 in this embodiment may specifically include a HEPA filter, a fiber filter element, an activated carbon filter, or the like. A HEPA filter is preferred in this embodiment. The HEPA filter is a high-efficiency particulate air filter (HEPA, short for High Efficiency Particulate Air Filter). The HEPA filter is a filter that efficiently filters out airborne particles, including dust, pollen, viruses, bacteria, mold spores, and other particles, down to a minimum of 0.3 microns. The filter efficiency is at least 99.97%, preventing particles from contaminating the suction element 20 and effectively improving the reliability and service life of the suction element 20.

[0069] The suction member 20 in this embodiment may specifically include a fan or a vacuum pump. Figure 2 As shown, when the sewage collection mechanism is installed in the cleaning device 01 (the cleaning device 01 can specifically be the main unit of the floor brush), the suction member 20 can be a fan. The fan is installed in the cleaning device 01 and the air outlet of the fan is aligned with the air outlet 103 of the sewage tank 10 to perform a negative pressure operation on the sewage tank 10. The installation is simple and convenient. When the sewage collection mechanism is installed in the base station 02, the suction member 20 can be a vacuum pump. The vacuum pump is connected to the air outlet 103 of the sewage tank 10 through a connecting pipe to achieve a negative pressure operation on the sewage tank 10. The specific structure and form of the suction member 20 can be determined according to the installation environment and actual needs, and this embodiment does not make the sole limitation here.

[0070] The second embodiment of the present invention provides a cleaning device 01, which includes a sewage collection mechanism. The structure of the sewage collection mechanism can be found in the first embodiment of the present invention, and will not be described in detail in this embodiment.

[0071] During the process of collecting sewage by the sewage collection mechanism of the cleaning device 01 (the source of the sewage can be the sewage generated by the cleaning parts of the cleaning device 01 during the cleaning process of the surface to be cleaned, or the sewage generated in the cleaning tank of the base station 02 when the cleaning parts return to the base station 02 for cleaning), the sewage enters the receiving chamber 101 tangentially along the tangential water inlet 102 of the sewage tank 10 under the suction action of the suction part 20. Then, under the action of centrifugal force, the sewage will flow into the receiving chamber 101 in a spiral shape from top to bottom along the inner wall surface of the receiving chamber 101. In this process, the flow force or flushing force generated by the spirally flowing sewage on the inner wall surface of the receiving chamber 101 can remove stains, garbage, etc. on the inner wall surface of the receiving chamber 101, thereby achieving the purpose of cyclonic flushing self-cleaning of the receiving chamber 101 of the sewage tank 10, eliminating the need for users to frequently clean the sewage tank 10 of the cleaning device 01, thereby improving the cleaning convenience of the sewage tank 10.

[0072] The third embodiment of the present utility model provides a base station 02, such as Figure 14 As shown, the base station 02 includes a sewage collection mechanism. The structure of the sewage collection mechanism can be found in the content provided in the first embodiment of the present invention, and will not be described in detail in this embodiment.

[0073] When base station 02 collects sewage through the sewage collection mechanism, the sewage, under the suction action of the suction member 20, enters the receiving chamber 101 tangentially along the tangential water inlet 102 of the sewage tank 10. Then, under the action of centrifugal force, the sewage flows in a spiral shape from top to bottom along the inner wall of the receiving chamber 101. During this process, the flow force or scouring force generated by the spirally flowing sewage on the inner wall of the receiving chamber 101 can remove stains, garbage, etc. on the inner wall of the receiving chamber 101, achieving the purpose of cyclonic scouring self-cleaning of the receiving chamber 101 of the sewage tank 10. This eliminates the need for users to frequently clean the sewage tank 10 of base station 02, thereby improving the cleaning convenience of the sewage tank 10.

[0074] The fourth embodiment of the present invention provides a cleaning system, comprising a cleaning device 01 and a base station 02, each of which includes a sewage collection mechanism. The structure of the sewage collection mechanism is described in detail in the first embodiment of the present invention and will not be further described in detail in this embodiment. After the cleaning device 01 returns to the base station 02, the sewage tank 10 of the cleaning device 01 will be connected to the sewage tank 10 within the base station 02 via a sewage collection pipe provided within the base station 02, so that the sewage tank 10 of the base station 02, under the suction action of the suction member 20, will collect the sewage in the sewage tank 10 of the cleaning device 01, and ultimately discharge the collected sewage into a sewer or sewage treatment system.

[0075] That is to say, in the process of the base station 02 and the cleaning equipment 01 in this embodiment collecting sewage through the sewage collection mechanism provided by the first embodiment of the utility model, the sewage tank 10 of the base station 02 and the cleaning equipment 01 can both achieve self-cleaning, thereby improving the user experience of the cleaning system.

[0076] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0077] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0078] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
