Detailed implementation manners
[0041] The following further describes the implementation manners of the present application in detail with reference to the drawings and embodiments. The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.
[0042] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "circumferential direction", "axial direction", "radial direction", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0043] In the description of this specification, the description referring to the term "one embodiment" means that the specific features, structures, materials or characteristics described in connection with the embodiment are included in at least one embodiment of the embodiments of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
[0044] In the related art, a dust collection device generally includes a housing and a dust suction device. When garbage is located inside the housing, the garbage is collected by the suction airflow of the dust suction device. During the operation of the dust collection device, some garbage, such as larger garbage like paper pieces and packaging bags, is likely to adhere to the inside of the housing and is not easily sucked in by the dust suction device, resulting in an unsatisfactory garbage collection ability of the dust collection device for the garbage inside the housing. When the dust collection device works for a long time, the garbage is likely to accumulate inside the housing, and it is necessary for the user to manually disassemble the housing for cleaning, which is also not conducive to the user's product usage experience.
[0045] In view of this, please refer to Figure 6 and Figure 7 , an embodiment of the present application provides a base station, including a base station body, a cleaning tray 200, and a dust collection device 100. The cleaning tray 200 is disposed on the base station body, and the dust collection device 100 is disposed on the cleaning tray 200. The dust collection device 100 can collect the garbage on the cleaning tray 200.
[0046] An embodiment of the present application provides a cleaning system, including a base station and a cleaning device. The cleaning device includes a device body and a rag. The device body can drive the rag to clean the stains attached to the ground. When the cleaning device is located on the cleaning tray 200, the base station body can clean the stains on the rag.
[0047] It should be noted that when the device body drives the rag to clean the stains attached to the ground, the stains will accumulate on the rag accordingly. When the cleaning device that has finished cleaning the ground returns to the base station and is located on the cleaning tray 200, the base station body can clean the stains adsorbed on the rag. Part of the stains that are easily soluble in water or have a small volume are mixed with water and drained away, and the other part of the stains with a larger volume will remain in the cleaning tray 200 or the dust collection device 100 and form garbage after drying. The remaining garbage will be sucked in by the dust collection device 100 to achieve self-cleaning of the base station.
[0048] Exemplarily, the cleaning device is a mopping robot, and the number of rags is two. Both rags are rotatably connected to the side of the device body close to the ground. The device body can move on the ground and drive the rags to rotate during the movement to clean the stains at various positions on the ground. The base station body includes a charging terminal and a water spray nozzle. The mopping robot can automatically stop on the cleaning tray 200. The water spray nozzle can rinse the rags of the mopping robot, and the charging terminal can charge the mopping robot. Part of the stains with a larger volume will remain on the cleaning tray 200 and form garbage after drying. The garbage remaining on the cleaning tray 200 can be sucked in by the dust collection device 100.
[0049] Please refer to Figures 1 to 5, an embodiment of the present application provides a dust collection device 100, which includes a housing 1, a dust suction device 2, and a flywheel 3.

The axial direction of the flywheel 3 intersects with the direction of the suction air flow of the dust suction device 2. The flywheel 3 can rotate to drive the garbage in the receiving cavity 13 to move towards the second opening 15.
[0050] In an embodiment of the present application, the dust suction device 2 sucks the receiving cavity 13 into a negative pressure state, so that the suction air flow of the dust suction device 2 provides a force for the garbage in the receiving cavity 13 to move towards the second opening 15. The flywheel 3 disposed in the receiving cavity 13 can rotate to disturb the garbage and drive the garbage to move towards the second opening 15.

[0061] In one embodiment, please refer to Figures 1 to 3 , the flywheel 3 is rotatably connected to the housing 1. The flywheel 3 includes a flywheel body 31 and fan blades 32 connected to the flywheel body 31. The suction air flow of the dust collection device 2 can drive the fan blades 32 to rotate to drive the garbage in the accommodation cavity 13 to move towards the second opening 15.
[0062] In the embodiment of the present application, the fan blades 32 rotate under the action of the suction air flow of the dust collection device 2. On the one hand, the fan blades 32 can disturb the garbage and drive the garbage to move towards the second opening 15. The dust collection device 2 and the flywheel 3 cooperate with each other, which is beneficial to improving the collection ability of the dust collection device 100 for the garbage in the accommodation cavity 13; on the other hand, the rotation of the fan blades 32 does not require an additional driving device and can rotate under the action of the suction air flow of the dust collection device 2, which is beneficial to reducing the power consumption of the dust collection device 100.
[0063] Exemplarily, the material of the fan blades 32 is not limited. For example, it can be plastic or rubber.
[0064] Exemplarily, the material of the flywheel body 31 is not limited. For example, it can be plastic or rubber.
[0065] Exemplarily, the connection manner between the flywheel body 31 and the fan blades 32 is not limited.
[0066] Exemplarily, the flywheel body 31 is rotatably connected to the housing 1, the fan blades 32 are fixedly connected to the flywheel body 31, and the action of the suction air flow of the dust collection device 2 on the fan blades 32 causes the fan blades 32 to drive the flywheel body 31 to rotate relative to the housing 1.
[0067] Exemplarily, the flywheel body 31 is rotatably connected to the housing 1, the fan blades 32 are rotatably connected to the flywheel body 31, the fan blades 32 can rotate along the circumferential direction of the flywheel body 31, and the action of the suction air flow of the dust collection device 2 on the fan blades 32 causes the fan blades 32 to rotate relative to the flywheel body 31.
[0068] In one embodiment, please refer to Figures 1 to 3 , the number of the fan blades 32 is multiple, and the multiple fan blades 32 are arranged at intervals along the circumferential direction of the flywheel body 31.
[0069] In the embodiments of the present application, a plurality of fan blades 32 are arranged at intervals along the circumferential direction of the flywheel body 31, so that within one rotation period of the flywheel 3, the number of times the fan blades 32 pass through the garbage can be increased, thereby increasing the frequency of the fan blades 32 disturbing the garbage and driving the garbage to move towards the second opening 15. Within one rotation period of the flywheel 3, the fan blades 32 can disturb the garbage multiple times and drive the garbage to move towards the second opening 15, which is beneficial to improving the garbage collection ability of the dust collection device 100 for the garbage in the accommodation cavity 13.
[0070] It can be understood that the number of the fan blades 32 is not limited.
[0071] Exemplarily, the number of the fan blades 32 is one. Within one rotation period of the flywheel 3, the fan blade 32 disturbs and drives the garbage to move towards the second opening 15 once.
[0072] Exemplarily, please refer to Figure 3 , the number of the fan blades 32 is three. The three fan blades 32 are evenly arranged at intervals along the circumferential direction of the flywheel body 31. Within one rotation period of the flywheel 3, each fan blade 32 can disturb and drive the garbage to move towards the second opening 15 once, so that the three fan blades 32 disturb and drive the garbage to move towards the second opening 15 three times in total.
[0073] In one embodiment, please refer to Figure 3 , the flywheel body 31 has an eccentric part 311, and the eccentric part 311 is configured to make the center of gravity of the flywheel 3 deviate from the rotation center of the flywheel body 31.
[0074] Exemplarily, the eccentric part 311 can be located at the fan blade 32.
[0075] Exemplarily, the eccentric part 311 can be located at one end of the fan blade 32 radially away from the flywheel body 31 along the flywheel body 31 to increase the weight and thickness of the root of the fan blade 32, so that the center of gravity of the flywheel 3 deviates from the rotation center of the flywheel body 31.
[0076] In the embodiments of the present application, the eccentric part 311 is configured to make the center of gravity of the flywheel 3 deviate from the rotation center of the flywheel body 31, so that when the flywheel 3 is stationary, the flywheel 3 can have a fixed posture under the action of gravity, and then it is convenient to adjust the fixed posture of the flywheel 3 in the stationary state to avoid the flywheel 3 blocking the first opening 14, and then enable the garbage to enter the accommodation cavity 13 as much as possible, which is beneficial to improving the garbage collection ability of the dust collection device 100 for the garbage in the accommodation cavity 13.
[0077] In one embodiment, please refer to Figure 3 , the flywheel 3 includes a flywheel body 31 and fan blades 32 connected to the flywheel body 31. When the flywheel 3 is stationary, the fan blades 32 are located in an area outside the position corresponding to the first opening 14.
[0078] Exemplarily, please refer toFigure 3 The flywheel 3 includes a flywheel body 31 and fan blades 32 connected to the flywheel body 31. The eccentric portion 311 is located on the flywheel body 31 and is disposed between two adjacent fan blades 32. When the flywheel 3 is stationary, the fan blades 32 are located in an area outside the corresponding position of the first opening 14. The first opening 14 is located between the fan blades 32 on both sides of the eccentric portion 311 along the circumferential direction of the flywheel 3 to prevent the fan blades 32 from blocking the first opening 14.
[0079] In the embodiment of the present application, the eccentric portion 311 of the flywheel body 31 is disposed between two adjacent fan blades 32 so that the center of gravity of the flywheel 3 deviates from the rotation center of the flywheel body 31. When the dust collection device 100 is not working and there is no suction airflow of the dust suction device 2 in the accommodation cavity 13, the eccentric portion 311 is always located below the flywheel body 31, so that the fan blades 32 on both sides of the eccentric portion 311 can maintain a large distance from the first opening 14. The first opening 14 is located between the fan blades 32 on both sides of the eccentric portion 311 along the circumferential direction of the flywheel 3 to reduce the possibility that the fan blades 32 hinder the garbage from entering the accommodation cavity 13 through the first opening 14, and then enable the garbage remaining on the cleaning tray 200 to enter the accommodation cavity 13 through the first opening 14 as much as possible. When the dust collection device 100 starts to work, under the combined action of the suction airflow of the dust suction device 2 and the rotating flywheel 3, it is convenient for the dust collection device 100 to suck more garbage located in the accommodation cavity 13. The garbage remaining on the cleaning tray 200 can enter the accommodation cavity 13 as much as possible first, and more garbage is easier to be collected by the dust collection device 100, which is conducive to improving the garbage collection ability of the dust collection device 100.
[0080] Exemplarily, please refer to Figure 3 The number of the fan blades 32 is three. The three fan blades 32 are evenly spaced along the circumferential direction of the flywheel body 31, and the included angle between two adjacent fan blades 32 is 120°. The eccentric portion 311 of the flywheel body 31 is disposed between two adjacent fan blades 32 so that the center of gravity of the flywheel 3 deviates from the rotation center of the flywheel body 31. When the dust collection device 100 is not working, the flywheel 3 always maintains the posture that the eccentric portion 311 is located directly below the flywheel body 31 under the action of the gravity of the eccentric portion 311, so that the fan blade 32 on the left side of the first opening 14 maintains a large distance from the first opening 14, and then enables the garbage remaining on the cleaning tray 200 to enter the accommodation cavity 13 through the first opening 14 as much as possible. When the dust collection device 100 starts to work, the fan blades 32 start to rotate clockwise under the action of the suction airflow of the dust suction device 2, so that the fan blades 32 start to disturb and drive more garbage in the accommodation cavity 13 to move towards the second opening 15. In one rotation cycle of the flywheel 3, each fan blade 32 can disturb and drive the garbage to move towards the second opening 15 once, so that the three fan blades 32 disturb and drive the garbage to move towards the second opening 15 three times in total.
[0081] It can be understood that the flywheel body 31 may not be provided with the eccentric part 311. Exemplarily, the mass of the flywheel body 31 is evenly distributed in the circumferential direction, the number of the fan blades 32 is three, and the three fan blades 32 are evenly spaced in the circumferential direction of the flywheel body 31.
[0082] It can be understood that the eccentric part 311 may also straddle the flywheel body 31 and the fan blade 32, and the eccentric part 311 is partially formed on the flywheel body 31 and partially formed on the fan blade 32.
[0083] In one embodiment, please refer to Figures 1 to 3 , along the axial direction of the flywheel body 31, the fan blade 32 extends from one end of the flywheel body 31 to the other end of the flywheel body 31.
[0084] In the embodiment of the present application, the fan blade 32 extends from one end of the flywheel body 31 to the other end of the flywheel body 31 along the axial direction of the flywheel body 31, increasing the area of the fan blade 32, and then increasing the contact area between the fan blade 32 and the garbage, which is beneficial to improving the efficiency of the fan blade 32 disturbing and driving the garbage in the accommodating cavity 13 to move towards the second opening 15, and then beneficial to improving the garbage collection ability of the dust collection device 100.
[0085] Exemplarily, please refer to Figure 3 , the number of the fan blades 32 is three, the three fan blades 32 are evenly spaced in the circumferential direction of the flywheel body 31, and along the axial direction of the flywheel body 31, the three fan blades 32 all extend from one end of the flywheel body 31 to the other end of the flywheel body 31 in a straight line.
[0086] Exemplarily, the number of the fan blades 32 is three, the three fan blades 32 are evenly spaced in the circumferential direction of the flywheel body 31, and along the axial direction of the flywheel body 31, the three fan blades 32 all extend from one end of the flywheel body 31 to the other end of the flywheel body 31 in a spiral shape.
[0087] It can be understood that the arrangement mode of the fan blade 32 along the axial direction of the flywheel body 31 may not be limited.
[0088] Exemplarily, the fan blade 32 includes a plurality of sub - blades, along the axial direction of the flywheel body 31, the plurality of sub - blades are spaced at intervals in a straight line, and the sub - blades corresponding to the plurality of fan blades 32 are evenly spaced in the circumferential direction of the flywheel body 31.
[0089] Exemplarily, the fan blade 32 includes a plurality of sub - blades, along the axial direction of the flywheel body 31, the plurality of sub - blades are spaced at intervals in a spiral shape, and the sub - blades corresponding to the plurality of fan blades 32 are evenly spaced in the circumferential direction of the flywheel body 31.
[0090] It can be understood that the relationship between the length of the fan blade 32 along the axial direction of the flywheel body 31 and the length of the flywheel body 31 along the axial direction may not be limited.
[0091] Exemplarily, the length of the fan blade 32 along the axial direction of the flywheel body 31 is less than the length of the flywheel body 31 along the axial direction, and the fan blades 32 are continuously arranged along the axial direction of the flywheel body 31.
[0092] In one embodiment, please refer to Figure 3 , the inclination direction of the end of the fan blade 32 away from the flywheel body 31 is opposite to the rotation direction of the flywheel body 31.
[0093] In the embodiment of the present application, the inclination direction of the end of the fan blade 32 away from the flywheel body 31 is opposite to the rotation direction of the flywheel body 31. On the one hand, it is beneficial to gather the suction airflow of the dust collection device 2 in the space surrounded by two adjacent fan blades 32 and the flywheel body 31, increasing the acting force of the suction airflow on the fan blade 32, and then increasing the acting force of the fan blade 32 to disturb and drive the garbage in the accommodation cavity 13 to move towards the second opening 15; on the other hand, the fan blade 32 is inclined towards the rotation direction away from the flywheel body 31. During the rotation of the fan blade 32, air can slide over the surface of the fan blade 32 with less resistance, which is beneficial to reducing the air resistance of the rotation of the fan blade 32. The fan blade 32 is inclined towards the rotation direction away from the flywheel body 31, which is beneficial to both increasing the acting force of the suction airflow on the fan blade 32, enabling the fan blade 32 to drive the garbage in the accommodation cavity 13 to move towards the second opening 15 with a greater force, and reducing the air resistance of the rotation of the fan blade 32, which is beneficial to increasing the rotation speed of the fan blade 32, and then beneficial to improving the garbage collection ability of the dust collection device 100.
[0094] Exemplarily, please refer to Figures 1 to 3 , the number of the fan blades 32 is three, and the three fan blades 32 are evenly arranged at intervals along the circumferential direction of the flywheel body 31. Along the axial direction of the flywheel body 31, the three fan blades 32 all extend linearly from one end of the flywheel body 31 to the other end of the flywheel body 31. Under the action of the suction airflow of the dust collection device 2, the suction airflow flows from the first opening 14 to the second opening 15, causing the flywheel 3 to rotate clockwise. Along the direction of the suction airflow, the fan blade 32 is arc-shaped, and the end of the fan blade 32 away from the flywheel body 31 is inclined towards the counterclockwise direction.
[0095] It can be understood that the setting method of the end of the fan blade 32 away from the flywheel body 31 is not limited.
[0096] Exemplarily, the fan blade 32 can be arranged along the radial direction of the flywheel body 31.
[0097] Exemplarily, the material of the fan blade 32 is relatively soft rubber, and the fan blade 32 is arranged along the radial direction of the flywheel body 31. When the fan blade 32 rotates under the action of the suction airflow of the dust collection device 2, under the action of rotational inertia, the fan blade 32 is arc-shaped, and the inclination direction of the end of the fan blade 32 away from the flywheel body 31 is opposite to the rotation direction of the flywheel body 31.
[0098] It can be understood that the relationship between the inclination direction of the end of the fan blade 32 facing away from the flywheel body 31 and the rotation direction of the flywheel body 31 need not be limited. Exemplarily, the inclination direction of the end of the fan blade 32 facing away from the flywheel body 31 may also be the same as the rotation direction of the flywheel body 31.
[0099] In one embodiment, please refer to Figure 3 , the accommodating cavity 13 includes a guiding cavity 131, a transition opening 132 and a transition cavity 133. The first opening 14, the guiding cavity 131, the transition opening 132, the transition cavity 133 and the second opening 15 are communicated in sequence. At least one cavity wall surface of the guiding cavity 131 is a first wall surface 1311. The guiding cavity 131 and the first opening 14 are both located below the first wall surface 1311. The first wall surface 1311 is arc-shaped. At least one opening wall surface of the transition opening 132 is a second wall surface 1321 connected to the first wall surface 1311. The second wall surface 1321 is arc-shaped. The second wall surface 1321 is tangent to the first wall surface 1311. At least one cavity wall surface of the transition cavity 133 is a third wall surface 1331. The third wall surface 1331 is tangent to the second wall surface 1321. The position where the first wall surface 1311 and the second wall surface 1321 are connected is the target position. The included angle between the tangent plane of the first wall surface 1311 at the target position and the third wall surface 1331 is an acute angle.
[0100] In the embodiment of the present application, the included angle between the tangent plane of the first wall surface 1311 at the target position and the third wall surface 1331 is an acute angle. The second wall surface 1321 is arc-shaped and the second wall surface 1321 is tangent to the first wall surface 1311 and the third wall surface 1331 respectively, so that the radius of the arc-shaped second wall surface 1321 is relatively smaller than the radius of the arc-shaped first wall surface 1311, and the angle corresponding to the arc of the second wall surface 1321 is larger. Consequently, the second wall surface 1321 has a larger radian. When the garbage located in the accommodating cavity 13 moves from the first opening 14 to the second opening 15 under the combined action of the suction airflow of the dust suction device 2 and the rotation of the fan blade 32, the garbage is not easily adsorbed on the second wall surface 1321 with a larger radian. When the garbage passes through the transition opening 132, the garbage can smoothly slide from the second wall surface 1321 into the transition cavity 133 along the second wall surface 1321 with a larger radian and then be sucked by the dust suction device 2, which is beneficial to improving the efficiency of the dust collection device 100 in collecting garbage.
[0101] Exemplarily, please refer to Figure 3 , the included angle shown as angle R1 in the figure is the included angle between the tangent plane of the first wall surface 1311 at the target position and the third wall surface 1331. The opening of the included angle between the tangent plane of the first wall surface 1311 at the target position and the third wall surface 1331 faces the second wall surface 1321.
[0102] Exemplarily, please refer to Figure 3Along the direction of the suction airflow of the dust collection device 2, the second wall 1321 is located on the side of the flywheel 3 close to the dust collection device 2, and the second wall 1321 is respectively connected to the arc-shaped first wall 1311 and the third wall 1331 on both sides along the direction of the suction airflow of the dust collection device 2, and the size of the transition opening 132 in the up and down direction is similar to the radial size of the flywheel body 31.
[0103] It can be understood that the relative arrangement relationship among the first wall surface 1311 , the second wall surface 1321 and the third wall surface 1331 is not limited.
[0104] Exemplarily, the first wall 1311 , the second wall 1321 , and the third wall 1331 may be located in the same plane.
[0105] In one embodiment, please refer to Figure 3 The surface below the guide cavity 131 is a guide surface 1312 . The guide surface 1312 is arc-shaped. The tangent plane of the guide surface 1312 located on the side of the flywheel 3 away from the first opening 14 intersects with the second opening 15 .
[0106] In the embodiment of the present application, the guide surface 1312 is in an arc shape, and the tangent plane of the guide surface 1312 located on the side of the flywheel 3 away from the first opening 14 intersects with the second opening 15. On the one hand, during the rotation of the fan blade 32, the fan blade 32 can cooperate with the arc-shaped guide surface 1312 for a longer distance. In the process of the fan blade 32 driving the garbage in the accommodating cavity 13 to move along the guide surface 1312 toward the second opening 15, the distance that the fan blade 32 and the guide surface 1312 abut against the garbage is longer, which is conducive to extending the distance and time that the fan blade 32 drives the garbage to move toward the second opening 15, and then is conducive to The effect of the fan blades 32 driving the garbage to move toward the second opening 15 is improved; on the other hand, the tangent plane of the guide surface 1312 located on the side of the flywheel 3 away from the first opening 14 intersects with the second opening 15. When the fan blades 32 drive the garbage to move toward the second opening 15 to the transition opening 132, the garbage is driven by the rotation of the fan blades 32 and restricted by the guide surface 1312. The direction of the speed of the movement of the garbage also intersects with the second opening 15. Under the action of the suction airflow of the dust collection device 2, the garbage can be sucked into the dust collection device 2 through the second opening 15 by the suction airflow, which is beneficial to improve the garbage collection ability of the dust collection equipment 100.
[0107] For example, see Figure 3 During the rotation of the fan blades 32, the gap between the guide surface 1312 and the fan blades 32 remains consistent. During the process of the fan blades 32 driving the garbage in the accommodating chamber 13 to move along the guide surface 1312 toward the second opening 15, the fan blades 32 and the guide surface 1312 jointly abut against the garbage, so that the garbage moves along the guide surface 1312 driven by the fan blades 32.
[0108] For example, seeFigure 3 In the figure, the plane shown by R2 is the tangent plane of the guiding surface 1312 on the side of the flywheel 3 away from the first opening 14, and the tangent plane R2 intersects with the second opening 15.
[0109] It can be understood that the shape of the guiding surface 1312 is not limited. Exemplarily, the guiding surface 1312 is a plane.
[0110] It can be understood that the positional relationship between the tangent plane of the guiding surface 1312 close to the transition cavity 133 and the second opening 15 is not limited. Exemplarily, the tangent plane of the guiding surface 1312 close to the transition cavity 133 does not intersect with the second opening 15.
[0111] In one embodiment, please refer to Figure 3 , the flywheel 3 includes a flywheel body 31 and fan blades 32 connected to the flywheel body 31. One end of the fan blades 32 along the radial direction of the flywheel body 31 away from the flywheel body 31 is attached to the guiding surface 1312 or close to the guiding surface 1312.
[0112] Exemplarily, one end of the fan blades 32 along the radial direction of the flywheel body 31 away from the flywheel body 31 is attached to the guiding surface 1312.
[0113] Exemplarily, please refer to Figure 3 , the range of the distance between one end of the fan blades 32 along the radial direction of the flywheel body 31 away from the flywheel body 31 and the guiding surface 1312 can be 0 to 7 millimeters.
[0114] In the embodiment of the present application, one end of the fan blades 32 along the radial direction of the flywheel body 31 away from the flywheel body 31 is attached to the guiding surface 1312 or close to the guiding surface 1312, so that the flywheel 3 can disturb the garbage in the accommodating cavity 13 as much as possible, facilitating the garbage to be sucked into the dust suction device 2 under the action of the suction airflow of the dust suction device 2, which is beneficial to improving the garbage collection ability of the dust collection device 100.
[0115] In one embodiment, please refer to Figures 1 to 3 , the housing 1 includes a detachable upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 enclose an accommodating cavity 13, and the flywheel 3 is rotatably connected to the upper housing 11.
[0116] In the embodiment of the present application, the upper housing 11 and the lower housing 12 are detachably connected, and the flywheel 3 is rotatably connected to the upper housing 11, so that when the upper housing 11 is detached from the lower housing 12, the flywheel 3 can also be detached together with the upper housing 11. Then, when the upper housing 11 is detached from the lower housing 12, the garbage remaining on the lower housing 12 can be directly cleaned, which is convenient for cleaning the dust collection device 100.
[0117] It can be understood that the connection position between the flywheel 3 and the housing 1 is not limited. Exemplarily, the flywheel 3 can also be rotatably connected to the lower housing 12.
[0118] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 , the lower housing 12 has a drain port 121 communicating with the accommodation cavity 13.
[0119] In the embodiment of the present application, during the cleaning process of the cleaning cloth of the cleaning device on the cleaning tray 200, the sewage formed by cleaning the cleaning cloth can flow through the cleaning tray 200 and the lower housing 12 and be discharged through the drain port 121. Part of the stains that are easily soluble in water or have a small volume follow the sewage and are discharged through the drain port 121, and another part of the stains with a larger volume can flow along the water flow into the dust collection device 100 and remain on the lower housing 12, forming garbage after air drying. The remaining garbage moves towards the second opening 15 under the combined action of the suction airflow of the dust suction device 2 and the flywheel 3 to be collected by the dust collection device 100, realizing the self-cleaning function of the base station.
[0120] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 , along the axial direction of the flywheel 3, the size of the first opening 14 is larger than the size of the second opening 15.
[0121] In the embodiment of the present application, along the axial direction of the flywheel 3, the larger first opening 14 can enable more garbage to enter the accommodation cavity 13 as much as possible first, facilitating the combined collection of the garbage located in the accommodation cavity 13 by the suction airflow of the dust suction device 2 and the flywheel 3. The smaller second opening 15 is beneficial to reducing the size of the dust suction device 2 and also beneficial to the convergence of garbage at the second opening 15, so that the garbage can enter the dust suction device 2 through the second opening 15.
[0122] Exemplarily, please refer to Figure 4 , in the figure, R3 is the size of the first opening 14 along the axial direction of the flywheel 3, R4 is the size of the second opening 15 along the axial direction of the flywheel 3, and the size R3 of the first opening 14 is larger than the size R4 of the second opening 15.
[0123] It can be understood that along the axial direction of the flywheel 3, the size relationship between the size of the first opening 14 and the size of the second opening 15 is not limited. Exemplarily, along the axial direction of the flywheel 3, the size of the first opening 14 can also be smaller than or equal to the size of the second opening 15.
[0124] In one embodiment, please refer to Figure 2 , along the direction of the suction airflow of the dust suction device 2, the size of the accommodation cavity 13 in the axial direction of the flywheel 3 gradually decreases from the first opening 14 towards the second opening 15.
[0125] In the embodiment of the present application, the dimension of the accommodation cavity 13 in the axial direction of the flywheel 3 gradually decreases from the first opening 14 towards the second opening 15. On the one hand, the relatively large first opening 14 enables more garbage to enter the accommodation cavity 13 as much as possible first, facilitating the suction air flow of the dust suction device 2 and the flywheel 3 to jointly collect the garbage located in the accommodation cavity 13. The relatively small second opening 15 is beneficial to reducing the size of the dust suction device 2 and also beneficial to the accumulation of garbage at the second opening 15, so that the garbage can enter the dust suction device 2 through the second opening 15. On the other hand, it makes the flow velocity of the suction air flow of the dust suction device 2 gradually increase, and also facilitates the garbage to enter the dust suction device 2 through the second opening 15.
[0126] In one embodiment, please refer to Figure 6 and Figure 7 , the cleaning tray 200 includes a tray body and scraping strips provided on the tray body. The housing 1 includes an upper housing 11 and a lower housing 12. The lower housing 12 is disposed on the tray body. The lower housing 12 has a drain port 121 communicating with the accommodation cavity 13. The scraping strips can scrape the garbage and sewage on the tray body, so that the accommodation cavity 13 can accommodate at least part of the garbage and the drain port 121 can discharge the sewage.
[0127] In the embodiment of the present application, the garbage and sewage on the tray body can gradually converge towards the dust collection device 100 under the disturbance of the scraping strips. The sewage is discharged through the drain port 121 on the lower housing 12, and the garbage enters the accommodation cavity 13 through the first opening 14. Under the combined action of the suction air flow of the dust suction device 2 and the flywheel 3, it is sucked into the dust suction device 2 through the second opening 15, which is beneficial to realizing the self-cleaning function of the base station.
[0128] In one embodiment, please refer to Figure 6 and Figure 7 , the number of the cleaning trays 200 is two, and the dust collection device 100 straddles the two cleaning trays 200.
[0129] In the embodiment of the present application, the garbage and sewage on the two tray bodies can gradually converge towards the same dust collection device 100 under the disturbance of the corresponding scraping strips. The two cleaning trays 200 share one dust collection device 100, which is beneficial to reducing the number of dust collection devices 100, and then beneficial to reducing the production cost of the cleaning system.

For those skilled in the art, the present application can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
