[0047] Since the sewage tank 10 of the existing cleaning device 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 to operate. In view of 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 suction port 103. The tangential water inlet 102 is an inlet opened on the outer peripheral wall of the sewage tank 10 along the tangent 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 tangent direction of the inner wall surface of the receiving chamber 101. The air suction 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 at one side of the sewage tank 10 close to the air suction port 103 and is connected to the accommodating chamber 101, that is, the tangential water inlet 102 is located at a position near the top of the sewage tank 10 itself on the outer peripheral wall. After the sewage enters the accommodating chamber 101 along the tangential water inlet 102, the sewage can generate centrifugal force under the action of the suction member 20 to flow in a spiral shape from the top of the accommodating chamber 101 close to the air suction port 103 to the bottom of the accommodating chamber 101, so that the sewage flowing in a spiral shape can flush and clean various parts of the inner wall surface of the accommodating chamber 101.

[0048] The suction piece 20 is installed on one side of the sewage tank 10 and is connected to the air suction port 103. The suction piece 20 is used to perform a negative pressure operation on the receiving chamber 101 through the air suction port 103, so that the sewage enters the tangential water inlet 102 and flows into the receiving chamber 101 in a spiral shape along the inner wall surface of the receiving chamber 101. The flow force or flushing force generated during the spiral flow of the sewage can flush away the stains and garbage on the inner wall surface of the receiving chamber 101, thereby realizing the self-cleaning operation of the sewage tank 10. In other words, the sewage tank 10 in this embodiment can collect sewage through the line of sight under the negative pressure operation of the suction piece 20, and can make the sewage enter the receiving chamber 101 in a spiral shape through the tangential water inlet 102 set on the sewage tank 10 and clean the inner wall surface of the receiving chamber 101, so that the sewage tank 10 can be self-cleaned without an additional power source, and the cleaning operation is convenient and energy-saving.

[0049] It can be seen that in this embodiment, the sewage tank 10 of the sewage collection mechanism is provided with a tangential water inlet 102, which is located on one side of the sewage tank 10 close to the air suction port 103 and is connected to the receiving chamber 101. After the sewage to be sucked enters the receiving chamber 101 tangentially along the tangential water inlet 102 under the suction action of the suction member 20, the sewage will generate a centrifugal force, and under the action of the centrifugal force, it 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 take away the stains, garbage, etc. on the inner wall surface of the receiving chamber 101, thereby achieving the purpose of cyclone flushing self-cleaning of the receiving chamber 101 of the sewage tank 10, without the need for the user 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 receiving 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 communicated with 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 the position of the accommodating chamber 101 away from the tangential water inlet 102, which can increase 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 the present embodiment, the diversion channel 104 has a longitudinal section along the first direction, and the area of ​​the longitudinal section gradually decreases in the direction away from the tangential water inlet 102. That is to say, 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 of sewage enters the diversion channel 104 from the tangential water inlet 102, the flow speed 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 the predetermined flow must flow at a faster speed to maintain the same volume flow rate). In the process of the sewage flowing in a spiral shape after the flow rate is 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 more smoothly divert the mainstream water column of sewage to the inner wall surface of the accommodating chamber 101, 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 receiving chamber 101. A chamfer 1041 is provided between the diversion channel 104 and the inner wall surface of the receiving chamber 101, and the chamfer 1041 is at least located on one side of the diversion channel 104 close to the bottom of the receiving chamber 101 along the first direction. The chamfer 1041 is provided on one side of the diversion channel 104 close to the bottom of the receiving chamber 101 along the first direction to 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 receiving chamber 101.

[0054] See also Figures 3 to 7 The sewage tank 10 in this embodiment includes a box body 11 and a box cover 12. A receiving groove 110 is arranged in the box body 11, and the inner wall surface of the receiving groove 110 is a cylindrical surface. The tangential water inlet 102 is arranged on the side wall of the box body 11 along the tangent direction of the inner wall surface of the receiving groove 110 and is connected with the receiving groove 110. The diversion channel 104 is arranged on the inner wall surface of the receiving groove 110. When the inner wall surface of the receiving groove 110 is a cylindrical surface, since the resistance encountered by the sewage in the spiral flow process is smaller, the cleaning force of the sewage on the inner wall surface of the receiving groove 110 will be increased, 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 on the receiving groove 110 and is surrounded by the inner wall surface of the receiving groove 110 to form a receiving cavity 101. When the sewage tank 10 is composed of the box body 11 and the box cover 12, it is not only easy to install, but also convenient to process the tangential water inlet 102 and the diversion flow channel 104. In this embodiment, before the box cover 12 and the box body 11 are buckled together, the tangential water inlet 102 and the diversion flow channel 104 are first processed on the box body 11, which can improve the processing convenience of the tangential water inlet 102 and the diversion flow channel 104, and the processing difficulty is low.

[0055] See also Figures 8 to 10In order to further reduce the processing difficulty of 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, and the first groove 1111 is recessed in the first direction and arranged in the first column section 111. The water pipe 1112 is located on the outer side of the first column section 111. Along the tangent direction of the inner wall surface of the first groove 1111, the water pipe 1112 is connected with a side of the first groove 1111 close to the box cover 12 and forms a 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 side of 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 along the first direction, and the through hole 1121 is connected with the first groove 1111 and surrounded by the first groove 1111 to form a receiving groove 110. When the box body 11 in this embodiment is composed of the first column segment 111 and the second column segment 112, the tangential water inlet 102 can be obtained by connecting the water pipe 1112 on the first column segment 111 with the first groove 1111 along the tangential direction of the first groove 1111, and the processing difficulty is low. Then the second column segment 112 is connected between the first column segment 111 and the box cover 12 to assemble the sewage tank 10, and the assembly is efficient and convenient.

[0056] The water delivery 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 parts of the cleaning device 01 in the process of cleaning the floor, table, wall, etc. can enter the receiving tank 110 from the water delivery pipe 1112 along the sewage suction pipe. The water delivery pipe 1112 can be laid on the outer side of the first column section 111 in a bent shape, but at this time, it may cause greater resistance when the sewage enters the receiving tank 110, which will reduce the centrifugal force generated when the sewage enters the receiving tank 110. In this regard, in order to ensure that the centrifugal force generated when the sewage enters the receiving tank 110 is greater, the water delivery pipe 1112 in this embodiment is laid straight along the first direction on the outer side of the first column section 111, thereby reducing the resistance before the sewage enters the receiving tank 110.

[0057] To further reduce the difficulty of processing the flow guide channel 104. Fig. 9 As shown, the first column segment 111 in 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 and arranged on the inner wall surface of the first groove 1111, and the second groove 1113 is located at the notch of the first groove 1111 close to the second column segment 112 and is connected to the tangential water inlet 102. When the second groove 1113 is recessed and arranged on 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 (such as Fig. 9In the structure shown in the figure, 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 this embodiment does not make a sole limitation. Fig.10 As shown, along the radial direction of the accommodating groove 110, the inner wall surface of the through hole 1121 close to the first column section 111 is recessed with a third groove 1122, and 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 is surrounded with the second groove 1113 to form a diversion channel 104. Specifically, the third groove 1122 and the second groove 1113 are mirror structures to each other, so that after the two are buckled together through each other's groove walls, not only will the tangential water inlet 102 not be blocked, but the diversion channel 104 will also be surrounded.

[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, so that the guide channel 104 can be obtained, 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, in this embodiment, a snap-fit ​​structure 113 is further provided between the first column segment 111 and the second column segment 112, and the snap-fit ​​structure includes a snap-fit ​​groove 131 and a snap-fit ​​flange 132. The snap-fit ​​groove 131 is matched with the snap-fit ​​flange 132, and the snap-fit ​​groove 131 is provided on at least one of the first column segment 111 and the second column segment 112, and the snap-fit ​​flange 132 is provided on at least the other of the first column segment 111 and the second column segment 112. Therefore, when assembling the first column segment 111 and the second column segment 112 together, it is only necessary to ensure that the snap-fit ​​flange 132 is snap-fitted into the snap-fit ​​groove 131, and the assembly is efficient and convenient, and it is not easy to have assembly deviation, which greatly improves the assembly accuracy between the first column segment 111 and the second column segment 112.

[0060] Specifically, Fig. 9 and Fig.10As shown, the engaging flange 132 in this embodiment is convexly arranged on the end side of the outer peripheral wall of the second column segment 112 close to the first column segment 111, and the engaging flange 132 is arranged and extended along the outer contour of the through hole 1121 and the third groove 1122. The engaging groove 131 is recessed and arranged on the end side of the outer peripheral wall of the first column segment 111 close to the second column segment 112, and the engaging groove 131 is arranged and extended along the outer contour of the first groove 1111 and the second groove 1113. When assembling the first column segment 111 and the second column segment 112, the engaging flange 132 can be embedded in the engaging groove 131, so that the two can be assembled accurately and efficiently, and the sealing of the receiving groove can be ensured.

[0061] The air suction port 103 in this embodiment is arranged 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, a large amount of airflow is mixed in the sewage. 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 further includes a water-gas separation component 30. The water-gas separation component 30 is installed on the box cover 12 and is located between the tangential water inlet 102 and the air suction port 103. The water-gas separation component 30 is used to separate the sewage from the airflow and discharge the airflow to the suction member 20 along the air suction port 103. After the sewage enters the accommodating chamber 101 from the tangential water inlet 102, the water-gas separation component 30 separates the sewage from the airflow and discharges the airflow from the air suction port 103 to the suction member 20, and the suction member 20 discharges 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, and the connecting hole connects the accommodating chamber 101 and the air extraction port 103. In order to improve the water-gas separation effect of the water-gas separation component 30, the water-gas 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, and the driving member 31 includes a first output shaft 310, and the first output shaft 310 can rotate around its own axis. The separation impeller 32 is connected to the first output shaft 310, and a ventilation gap 320 connected to the connecting hole is provided on the separation impeller 32, 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 can drive the first output shaft 310 to drive the separation impeller 32 to rotate. The separation impeller 32 separates the sewage and the garbage in the sewage from the airflow during the rotation process. The sewage and the garbage in the sewage enter the accommodating chamber 101 for temporary storage. The airflow flows to the connecting hole along the ventilation gap 320 of the separation impeller 32, and then flows from the connecting hole along the air suction port 103 to the suction member 20 and is discharged by the suction member 20. Since at least a portion of the separation impeller 32 along the first direction is arranged opposite to the tangential water inlet 102, when the sewage enters the accommodating chamber 101 from the tangential water inlet 102, the sewage and the airflow can be separated quickly and timely under the action of the separation impeller 32, and the separated airflow flows out of the accommodating chamber 101 along the ventilation gap 320 of the separation impeller 32, and the water-gas separation is efficient and timely.

[0063] The driving member 31 in this embodiment can be a combination of a motor and a transmission component, or a motor alone. When it is a combination of a motor and a transmission component, the transmission component is connected between the motor and the first output shaft 310. At this time, the transmission component may specifically include structures such as pulleys and transmission belts. The motor shaft and the first output shaft 310 are both provided with pulleys, and the transmission belt is provided on the pulleys on the motor and the first output shaft 310. When the motor is started, the first output shaft 310 is driven to rotate through the transmission of the pulley and the transmission belt. However, this method has a relatively complex structure and will occupy a larger installation space of the box cover 12. In this regard, the driving member 31 in this embodiment is preferably a motor, which directly drives the first output shaft 310 through the motor to drive the separation impeller 32 to rotate to perform the water-gas separation operation, so that the structure of the water-gas separation component 30 is more concise and easy to assemble, saving the installation space of the box cover 12, and improving 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 one side of the separation impeller 32 close to the driving member 31. The outer peripheral wall and the groove 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 airflow can enter the first mounting groove 321 from the ventilation gap 320 and then be discharged from the connecting hole to the air suction port 103. The first output shaft 310 is connected to the groove 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 has low 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 groove 110, the projected outer contours of the tangential water inlet 102 and the guide channel 104 are both located within the projected outer contour of the separation impeller 32, so that the separation impeller 32 can separate the sewage and the airflow more timely and effectively. The side of the separation impeller 32 away from the box cover 12 can extend to the lower part of the side of the tangential water inlet 102 close to the bottom of the receiving chamber 101, so that the separation impeller 32 can discharge the airflow separated from the spiral flow to the connecting hole in a timely manner.

[0065] At the same time, in order to improve the assembly convenience between the water-gas separation assembly 30 and the box cover 12, see Figure 7 as well as Figures 11 to 13, the box cover 12 in this embodiment 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 extraction port 103 is arranged on the side of the main body 121 away from the mounting portion 122, and the first communicating hole 1211 is arranged through the main body 121 and communicates with the air extraction port 103. The mounting portion 122 is connected to the main body 121, and a second mounting groove 1221 is arranged on a side of the mounting portion 122 close to the main body 121, and a portion of the second mounting groove 1221 away from the main body 121 extends out of an end of the mounting portion 122 away from the main body 121, and the second communicating hole 1222 is arranged through the mounting portion 122 along the first direction, and the second communicating hole 1222 is arranged around the outer periphery of the second mounting groove 1221 and communicates with the first communicating hole 1211 and the accommodating chamber 101. The motor as the driving member 31 is installed in the second installation groove 1221 and the first output shaft 310 passes through the bottom of the second installation groove 1221 and is connected to the separation impeller 32. A side of the installation portion 122 close to the housing 11 is provided with an avoidance groove 1223 adapted to one end of the separation impeller 32 close to the installation portion 122. The avoidance groove 1223 is arranged around the outer periphery of the second connecting hole 1222. One end of the separation impeller 32 close to the installation portion 122 is located in the avoidance groove 1223 and is gap-matched with the avoidance groove 1223. Thus, not only the ventilation gap 320 of the separation impeller 32 can be connected to the second connecting hole 1222, but also the separation impeller 32 can rotate relative to the installation portion 122 driven by the first output shaft 310.

[0066] As can be seen from the above, in this embodiment, the box cover 12 is divided into a main body 121 and a mounting portion 122. After the air extraction port 103 and the first connecting hole 1211 are set on the main body 121, the motor is installed in the second mounting groove 1221 of the mounting portion 122 and connected to the separation impeller 32, and then the mounting portion 122 is installed between the main body 121 and the box body 11 to assemble the sewage tank 10. In this embodiment, the assembly convenience between the water-gas separation component 30 and the box cover 12 is improved through such a box cover 12 structure, and the structure between the water-gas separation component 30 and the box cover 12 is made more compact and reliable. The outer peripheral surface of the mounting portion 122 is sleeved with the box body 11. At this time, in order to improve the assembly sealing between the box cover 12 and the box body 11, in this embodiment, a sealing member 123 can also be set between the mounting portion 122 and the box body 11, so that the assembly gap between the mounting portion 122 and the box body 11 is sealed by the sealing member 123. 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 performance of the sewage tank 10 and further improving the suction efficiency of the suction member 20 when performing a negative pressure operation on the sewage tank 10. The sealing member 123 may be at least one of a sealing rubber ring and a sealing silicone ring.

[0067] In addition, in order to further filter the liquid and garbage in the airflow and prevent the liquid and / or garbage in the airflow from still existing in the airflow and thus causing damage to 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, such as Fig.11 As shown, the first connecting hole 1211 is arranged to penetrate the bottom of the third installation groove 1212 along the first direction. 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 from the second communication hole 1222, it first passes through the filter element 40 to further filter the water vapor and garbage in the airflow, and the filtered purer airflow is discharged through the suction element 20 without causing damage to the suction element 20, thereby improving the service life of the sewage collection mechanism.

[0068] The filter element 40 in this embodiment may specifically include one of a HEPA filter, a fiber filter element, an activated carbon filter, etc. In this embodiment, a HEPA filter is preferred, which is a high-efficiency particulate air filter (HEPA for short, full name High Efficiency Particulate Air Filter). The HEPA filter is a filter that can efficiently filter particles in the air, and can effectively filter out dust, pollen, viruses, bacteria, mold spores and other particles in the air, with a minimum of 0.3 micron particles, and a filtration efficiency of at least 99.97%, which can prevent particles from contaminating the suction piece 20, thereby effectively improving the reliability and service life of the suction piece 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 be specifically the main unit of the floor brush), the suction member 20 can be a fan, which 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 negative pressure extraction on the sewage tank 10, which is simple and convenient to install. When the sewage collection mechanism is installed in the base station 02, the suction member 20 can be a vacuum pump, which is connected to the air outlet 103 of the sewage tank 10 through a connecting pipe to achieve negative pressure extraction 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 is not limited to this.

[0070] The second embodiment of the present invention provides a cleaning device 01, and the cleaning device 01 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.

[0071] During the process of the cleaning device 01 collecting sewage through the sewage collection mechanism (the source of the sewage can be the sewage generated by the surface to be cleaned during the cleaning process of the cleaning parts of the cleaning device 01, 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, and then 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 under the action of centrifugal force. 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 take away the 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, without the need for the user to frequently clean the sewage tank 10 of the cleaning device 01, thereby improving the cleaning convenience of the sewage tank 10.

[0072] A third embodiment of the present invention provides a base station 02, such as Fig.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 this embodiment will not be repeated here.

[0073] When the base station 02 collects sewage through the sewage collection mechanism, the sewage enters the receiving chamber 101 tangentially along the tangential water inlet 102 of the sewage tank 10 under the suction of the suction member 20, and then the sewage flows into the receiving chamber 101 in a spiral shape from top to bottom along the inner wall surface of the receiving chamber 101 under the action of centrifugal force. 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 the stains, garbage, etc. on the inner wall surface of the receiving chamber 101, thereby achieving the purpose of cyclone flushing self-cleaning of the receiving chamber 101 of the sewage tank 10, and there is no need for the user to frequently clean the sewage tank 10 of the 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, which includes a cleaning device 01 and a base station 02, and the cleaning device 01 and the base station 02 both include a sewage collection mechanism. For the structure of the sewage collection mechanism, please refer to the content provided in the first embodiment of the present invention, and this embodiment will not be repeated here. 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 in the base station 02 through the sewage collection pipe provided in the base station 02, so that the sewage tank 10 of the base station 02 can collect the sewage in the sewage tank 10 of the cleaning device 01 under the suction action of the suction member 20, and finally discharge the collected sewage into the sewer or sewage treatment system.

[0075] That is to say, during the process of the base station 02 and the cleaning device 01 in this embodiment collecting sewage through the sewage collection mechanism provided by the first embodiment of the present invention, the sewage tank 10 of the base station 02 and the cleaning device 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 here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. 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 figure.
