Description

Technical Field

[0001] This disclosure relates to cleaning electrical equipment, and more specifically, to cleaning components and electrical equipment. Background Technology

[0002] Floor cleaning equipment is widely used. It typically comprises one or more rollers rotating along a horizontal axis as cleaning tools. During cleaning, the rollers contact the surface to be cleaned and can be cleaned with the aid of cleaning fluid. The cleaning fluid, such as water, is applied to the surface or the rollers during the cleaning process. Subsequently, the applied cleaning fluid, along with the cleaned dirt, is transferred to a waste collection container by the rollers. Because of contact with dirt and waste fluid, the rollers often become quite dirty after surface cleaning. In existing technology, an additional base station is set up, and the cleaning equipment pauses its cleaning operation and returns to dock at the base station. The cleaning operation on the rollers is then performed using the docking position of the base station and the stored cleaning fluid. However, because the cleaning equipment needs to return and dock at the base station, cleaning the rollers becomes more cumbersome and time-consuming.

[0003] In addition, if the roller is already very dirty during the surface cleaning process and is not cleaned in time, the cleaning ability of the cleaning equipment will be greatly reduced. This makes the self-cleaning function of the roller during use an important function, which can improve the cleaning effect of the cleaning equipment to a certain extent by keeping the roller itself clean. Utility Model Content

[0004] One aspect of this disclosure provides a cleaning assembly. The cleaning assembly includes: a roller; a scraper abutting a cylindrical surface against one side of the roller; a roller cover connected to the scraper and surrounding the roller; a collection chamber formed by the cylindrical surface portion, the scraper, and the roller cover; a supply channel communicating with the collection chamber and for pouring cleaning fluid into the collection chamber or onto the surface of the roller; and a drainage mechanism communicating with the collection chamber and for allowing liquid to drain from the collection chamber. The cleaning assembly is configured such that during a roller self-cleaning operation, the drainage mechanism is closed to allow cleaning fluid to accumulate in the collection chamber and not be discharged, and the accumulated cleaning fluid can be used to clean the roller when the roller is driven to rotate in a direction toward the scraper.

[0005] According to embodiments of this disclosure, a portion of the cylindrical surface of the roller, the roller cover, and the scraper of the cleaning assembly form a collection chamber. During the self-cleaning process, cleaning fluid can be poured into the collection chamber and the roller can be driven to rotate, thereby cleaning the roller with the cleaning fluid accumulated in the collection chamber. This process can be performed anytime and anywhere, eliminating the need for electrical equipment to return to the base station, improving the cleaning effect of the roller, and saving time.

[0006] In some embodiments, the cleaning component is further configured to activate a drain mechanism during or after the roller self-cleaning operation to drain the contaminated liquid from the collection chamber. In such embodiments, draining the contaminated liquid can replace liquid that is no longer suitable for cleaning the roller, thereby improving cleaning efficiency.

[0007] In some embodiments, the draining mechanism includes: a draining channel, the liquid inlet of which communicates with a collection chamber, and a liquid outlet for draining waste liquid; and a closing part, which is positioned adjacent to the liquid outlet and configured to open or close the liquid outlet. In such embodiments, the opening and closing of the draining mechanism can be achieved by the opening and closing of the closing part and the draining channel.

[0008] In some embodiments, the system further includes a receiving cavity for accommodating the collection chamber and the roller, and a moving mechanism for moving the collection chamber. A closing part is disposed on the inner wall of the receiving cavity, and the collection chamber is configured to move between a first position and a second position under the drive of the moving mechanism. When the collection chamber is in the first position, the closing part closes the drain channel, and when the collection chamber is in the second position, the closing part is spaced apart from the liquid outlet. In such an embodiment, the opening and closing of the closing part and the drain channel can be achieved through relative movement between them.

[0009] In some embodiments, the closure includes a soft rubber capable of covering the liquid outlet. In such embodiments, the use of soft rubber provides a cushioning effect and achieves a better closure performance.

[0010] In some embodiments, the moving mechanism has a lifting member, and the cleaning assembly is configured to: lift the collection chamber to a first position to close the drainage mechanism; and lower the collection chamber to a second position to allow waste liquid to enter the waste liquid tank from the liquid outlet. In such embodiments, lifting the roller so that it is no longer in contact with the surface to be cleaned during self-cleaning operations improves self-cleaning efficiency.

[0011] In some embodiments, the moving mechanism includes a rotating shaft, and the collecting chamber further includes a support on the other side of the roller, wherein the rotating shaft is configured to drive the support to rotate the collecting chamber about the rotating shaft between a first position and a second position.

[0012] In some embodiments, the collection chamber further includes a first sidewall and a second sidewall, extending from an end of the roller cover in a direction parallel to the axis of the roller and in a direction perpendicular to the axis, respectively, wherein the roller is rotatably supported between the first sidewall and the second sidewall. In such an embodiment, the roller is fixed to the collection chamber such that the roller can move with the collection chamber.

[0013] In some embodiments, the drainage mechanism includes a pump for pumping wastewater from the collection chamber to a wastewater tank for storing wastewater.

[0014] In some embodiments, the liquid supply channel is provided on the roller cover.

[0015] A second aspect of this disclosure provides an electrical device. The electrical device includes: a main body; a cleaning component according to a first aspect of this disclosure, disposed within the main body; a waste liquid tank configured to receive waste liquid from the cleaning component; a control unit for controlling the cleaning component; and a clean liquid tank for supplying cleaning fluid to the cleaning component.

[0016] According to one or more embodiments, the electrical equipment includes any of the following: a robot vacuum cleaner, a robot mopping, a floor scrubber, a robot vacuum and mop combo, or a handheld electric mop.

[0017] The foregoing description of the various aspects and advantages of the cleaning components also applies accordingly to the electrical equipment according to this disclosure, and therefore will not be repeated here. Attached Figure Description

[0027] Figure 8 A block diagram of an example device that can be used to implement embodiments of the present disclosure is shown. Detailed Implementation

[0028] Unless otherwise specified, corresponding numbers and symbols in the different figures generally refer to corresponding areas. The figures are drawn to clearly illustrate relevant aspects of the embodiments and are not necessarily drawn to scale. The edges of features drawn in the figures do not necessarily indicate the termination of the feature range.

[0029] In the following description, various specific details are shown to provide a thorough understanding of various examples of embodiments according to the description. Embodiments may be obtained without one or more specific details, or by utilizing other methods, components, materials, etc. In other instances, known structures, materials, or operations are not shown or described in detail so as not to obscure the various aspects of the embodiments.

Therefore, phrases such as "in an embodiment," "in one embodiment," etc., that may appear in various aspects of this specification do not necessarily refer precisely to the same embodiment. Furthermore, specific configurations, structures, or features may be combined in any suitable manner in one or more embodiments.

[0031] Unless otherwise stated, when referring to two elements connected together, it means that there is no direct connection without any intermediate elements, and when referring to two elements coupled together, it means that the two elements can be connected or they can be coupled via one or more other elements.

[0032] The title / reference numerals used herein are for readability purposes only and do not limit the scope of protection or the scope of the embodiments. Identical or similar elements are identified using the same reference numerals.

[0033] As discussed above, in related technologies, electrical equipment typically needs to return to the base station after operating for a period of time, docking inside the base station to allow the rollers in the cleaning equipment to self-clean. After self-cleaning is complete, it leaves the base station to perform the cleaning operation again. This setup is inflexible, wastes time, and results in a poor user experience.

[0034] In view of this, the present disclosure provides a cleaning assembly capable of performing self-cleaning operations at any time. In this cleaning assembly, a portion of the cylindrical surface of the roller, the roller cover, and the scraper form a collection chamber. During the self-cleaning process, cleaning fluid can be poured into the collection chamber and the roller can be driven to rotate, thereby cleaning the roller using the cleaning fluid accumulated in the collection chamber. This process can be performed anytime and anywhere, eliminating the need for electrical equipment to return to the base station, improving the cleaning effect of the roller, and saving time.

[0035] Figure 1 A partial cross-sectional view of an example electrical device 1 according to an embodiment of the present disclosure is shown. Figure 1 As shown, the electrical device 1 is capable of traveling across a surface to be cleaned, such as a floor, to clean the surface. The electrical device 1 includes a main body 30. Within the main body 30 are disposed a cleaning component 10 for performing cleaning operations, a wastewater tank 20 for receiving liquid from the cleaning component 10, and a cleaning fluid tank 40 for the cleaning component 10. Furthermore, the electrical device 1 includes a control unit 50 for receiving instructions from a user and executing those instructions to control the electrical components in the electrical device 1. The control unit 50 may, for example, control the cleaning component 10 to perform a self-cleaning operation according to embodiments of this disclosure. In some embodiments, the main body 30 may include a cleaning module and a main unit module. For example, the cleaning module may include the cleaning component 10, the wastewater tank 20, and the cleaning fluid tank 40, while the main unit module may include the control unit 50 and a power supply for energizing the electrical device 1.

[0036] The cleaning assembly 10 includes a roller 100. The roller 100 is rotatable about a rotation axis A in a first rotation direction R1 to clean the surface to be cleaned. The cleaning assembly 10 also includes a scraper 210. The scraper 210 abuts against a cylindrical surface 110 of the roller 100 facing the waste tank 20. The cleaning assembly 10 also includes a roller cover 230. The roller cover 230 is connected to the scraper 210 and surrounds at least a portion of the roller 100. The roller cover 230, the scraper 210, and a portion 220 of the cylindrical surface of the roller together form a collection chamber 200 to collect cleaning fluid in the collection chamber 200.

[0037] In addition, the cleaning assembly 10 also includes a liquid supply channel 300. The liquid supply channel 300 communicates with the liquid collection chamber 200 and is used to pour cleaning liquid into the liquid collection chamber 200 or the surface of the roller 100, allowing the cleaning liquid to collect in the liquid collection chamber 200. It is understood that by pouring in cleaning liquid, such as water, the roller 100 is moistened, enabling the cleaning equipment to perform cleaning operations such as wet mopping. Simultaneously, since one end of the scraper 210 abuts against the roller 100, liquid on the roller 100 can be scraped off and collected in the aforementioned liquid collection chamber 200. The cleaning assembly 10 also includes a draining mechanism 400. The draining mechanism 400 communicates with the liquid collection chamber 200 and is used to allow liquid in the liquid collection chamber 200 to drain out. Figure 1 In the illustrated embodiment, the draining mechanism 400 is oriented toward the waste tank 20 to allow liquid in the collection chamber 200 to drain into the waste tank 20.

[0038] During the cleaning operation, the electrical device 1, which has the cleaning component 10, travels on the surface to be cleaned, for example, under the action of a drive wheel, while the roller 100 rotates in a first rotational direction R1 opposite to that of the drive wheel to perform the cleaning of the surface. Upon contact with the surface to be cleaned, the roller 100 absorbs dirt and / or liquid from the surface. As it continues to rotate, the dirt and / or liquid remaining on the roller 100 reaches the scraper 210, is scraped off, and accumulates at the point where the scraper 210 abuts against the portion 220 of the roller 100 that forms the collection chamber, and is then allowed to be discharged into the wastewater tank 20 via the drainage mechanism 400.

[0039] The real-time self-cleaning function of the roller 100 is activated when the cleaning equipment 1 automatically identifies that the dirt level of the roller reaches a certain threshold, or when the cleaning equipment 1 is performing a cleaning operation on the surface to be cleaned but there is a predetermined interval, or after the cleaning equipment 1 has completed the cleaning operation on the surface to be cleaned, or when the user determines that the roller 100 needs to perform self-cleaning.

[0040] Specifically, when the control unit 50 receives a command to perform a self-cleaning operation on the roller, the control unit 50 closes the drain mechanism 400 and pours cleaning fluid into the collection chamber 200 through the supply channel 300. After entering the collection chamber 200, the cleaning fluid is absorbed by the surface of the roller 100. The surface of the roller 100 is, for example, in an interference fit with the scraper 210, so that when the roller 100 is driven to rotate toward the scraper 210, the scraper 210 scrapes off the cleaning fluid absorbed by the surface of the roller 100, causing it to accumulate in the closed collection chamber 200. As the roller 100 rotates continuously, the cleaning fluid accumulated in the collection chamber 200 can repeatedly clean the roller 100. Thus, the roller 100 can be cleaned at any time without placing the electrical equipment 1 in a dedicated cleaning station. Afterwards, when the cleaning fluid in the collection chamber 200 is sufficiently dirty, or after a predetermined self-cleaning time or a predetermined number of roller rotations, the drain mechanism is opened, and the dirty fluid in the collection chamber 200 continues to flow into the dirty fluid tank 20. Alternatively, the cleaning fluid can be poured directly into other parts of the collection chamber 200 instead of directly onto the absorbent surface of the roller.

[0041] It should be understood that, although in Figure 1 In the illustrated embodiment, electrical device 1 is a cleaning robot. According to this disclosure, electrical device 1 can also be a mopping robot, a floor scrubber, a sweeping and mopping robot, a handheld electric mop, or any device with a cylindrical rotating part for cleaning surfaces to be cleaned. Furthermore, Figure 1 The positions of the components in the electrical device 1 shown are merely exemplary. The positions of the components may include all structures capable of enabling the self-cleaning operation of embodiments of this disclosure.

[0042] Figure 2A partial cross-sectional view of an example cleaning component 10 according to an embodiment of the present disclosure is shown. Figure 2 As shown, the cleaning assembly 10 includes a roller 100. The roller 100 is rotatable about axis A in a first rotational direction R1 to clean the surface to be cleaned. The collection chamber 200 of the cleaning assembly 10 is connected to the roller 100. The collection chamber 200 includes a scraper 210, a cylindrical portion 220 of the roller, and a roller cover 230.

[0043] The roller 100 of the cleaning assembly 10 includes a cylindrical body located in the center and a cylindrical surface 110 circumferentially disposed on the outer side of the body around axis A. In some embodiments, the cylindrical surface 110 may include a flexible absorbent material with bristles. A scraper 210 of the collection chamber 200 abuts against the cylindrical surface 110 and is used to collect liquid from the cylindrical surface 110 of the roller 100. The scraper 210 includes an outer end connected to the roller cover 230 and an inner end abutting against the cylindrical surface 110. The scraper 210 defines a portion of the bottom of the collection chamber 200. The outer end of the scraper 210 abuts against the cylindrical surface 110 at a first cylindrical surface position 111.

[0044] The roller cover 230 of the collection chamber 200 extends from the outer end of the scraper 210 about axis A in a second rotational direction opposite to the first rotational direction R1 and is spaced apart from the cylindrical surface 110. A portion of the roller cover 230 connected to the scraper 210 defines the side of the collection chamber 200, and the remaining portion defines the upper part of the collection chamber 200.

[0045] exist Figure 2 In the illustrated embodiment, a liquid supply channel 300 is formed in the roller cover 230, and the opening of the liquid supply channel 300 faces the second cylindrical position 112 on the cylindrical surface 110, such that when liquid flows from the liquid supply channel 300 onto the cylindrical surface 110, the liquid is absorbed by the cylindrical surface 110. When the roller 100 is driven to rotate toward the scraper 210, the cylindrical surface 110 of the roller 100 contacts the scraper 210, and the scraper 210 scrapes the cleaning liquid absorbed by the cylindrical surface 110 of the roller 100, causing the cleaning liquid to accumulate in the collection chamber 200 with the outlet closed. That is, the portion of the cylindrical surface 110 between the first cylindrical position 111 and the second cylindrical position 112 defines the other side of the collection chamber 200.

[0046] The cleaning assembly 10 also includes a drainage mechanism 400. The drainage mechanism 400 communicates with the collection chamber 200 and allows liquid in the collection chamber 200 to drain. Figure 2As shown, the drainage mechanism 400 includes a drainage channel 410. The drainage channel 410 includes a liquid inlet 411 and a liquid outlet 412 located at both ends. The liquid inlet 411 is located on the roller cover 230 so that the drainage channel 410 communicates with the collection chamber 200. In the assembled state, the liquid outlet 412 faces the waste liquid tank 20 so that liquid from the collection chamber 200 can be discharged into the waste liquid tank 20 via the liquid outlet 412.

[0047] In addition, the drainage mechanism 400 also includes a closing part 420. The closing part 420 is positioned adjacent to the liquid outlet 412 and configured to open or close the liquid outlet 412. In some embodiments, the closing part 420 may be hinged to the liquid outlet 412, thereby enabling the liquid outlet 412 to be opened or closed under the control of the control unit 50. It should be understood that the term "closed" here means that the closing part 420 covers the liquid outlet 412 so that the liquid in the collection chamber 200 can be stored and used to achieve the self-cleaning of the roller 100, including situations where the closing part 420 completely seals the liquid outlet 412 or does not completely seal it, causing a small amount of dirty liquid to flow out from the liquid outlet 412. When it is not completely sealed, although some dirty liquid flows out, it flows into the dirty liquid tank 20, which is still a feasible implementation.

[0048] In this embodiment, when the closing part 420 closes the liquid outlet 412, the liquid from the liquid supply channel 300 will accumulate in the collection chamber 200 formed by the portion of the cylindrical surface 110 between the first cylindrical surface position 111 and the second cylindrical surface position 112, the scraper 210, and the roller cover 230. Simultaneously, the control unit 50 controls the roller 100 to rotate in the first rotation direction, i.e., towards the scraper 210. At this time, the liquid in the collection chamber 200 ensures that a portion of the liquid is always in contact with a portion of the roller 100, thus continuously contacting the cylindrical surface 110 of the roller 100 as the roller 100 rotates, thereby cleaning the cylindrical surface 110 and achieving a self-cleaning effect for the roller.

[0049] In some embodiments, when the control unit 50 detects that the accumulated liquid has reached a predetermined volume, the control unit 50 may stop pouring cleaning fluid through the liquid supply channel 300. In other embodiments, when the control unit 50 determines that the accumulated liquid has become dirty and is no longer suitable for cleaning, or when the drum rotation cleaning has reached a certain time, the number of rotations has reached a preset threshold, or other limiting conditions, the control unit 50 may open the drain mechanism 400 to drain the dirty liquid. After determining that the dirty liquid has been drained, the control unit 50 may close the drain mechanism 400 again and re-pour cleaning fluid to clean the drum 100. Thus, the cleaning operation is repeated until the drum 100 self-cleans to the preset requirement.

[0050] Figure 3AA perspective view of a portion of an example electrical device according to an embodiment of the present disclosure is shown. Figure 3A As shown, the portion shown includes a cleaning assembly 10 according to an embodiment of the present disclosure and a waste tank 20 corresponding to the cleaning assembly 10. The waste tank 20 includes a tank opening 21. The tank opening 21 is aligned with the draining mechanism 400 of the cleaning assembly 10, such that waste liquid from the collection chamber of the cleaning assembly 10, guided by the draining mechanism 400, can enter the waste tank 20 through the tank opening 21.

[0051] exist Figure 3A The main image shows the roller cover 230 of the cleaning assembly 10. The roller cover 230 includes end caps forming a first sidewall 260 and a second sidewall 270 of the collection chamber 200. The roller 100 is rotatably supported between the first sidewall 260 and the second sidewall 270. The cleaning assembly 10 also includes a bracket 250 on the opposite side of the roller 100 opposite to the scraper. The bracket 250 is fixed to the body 30 of the electrical device 1.

[0052] The drainage channel 410 of the drainage mechanism 400 extends from the drum cover 230 in a direction away from the drum 100, such that the liquid outlet 412 of the drainage channel 410 faces the opening 21 of the waste liquid tank 20.

[0053] Figure 3B A schematic diagram of an example portion of an example scraper and roller according to an embodiment of the present disclosure is shown. Figure 3B As shown, the portion shown does not include the top of the roller cover 230; it is understood that this top portion is omitted here for clearer illustration of the drainage channel 410 and the collection chamber 200. (As shown) Figure 3B As shown, the scraper 210 is in close contact with the cylindrical surface 110. The drainage mechanism 400 is located at the center in the direction parallel to the axis of the roller 100. In some embodiments, the distance of the scraper 210 from the tangential surface A is U-shaped in the direction parallel to the axis of the roller 100, and the bottom of the U-shape is located at the center of the drainage mechanism 400, so that the sewage in the collection chamber can be guided to the drainage mechanism 400 under the action of gravity.

[0054] In some embodiments, the drain channel 410 of the drain mechanism 400 may be fixed in the electrical device 1, and the closing part 420 may move toward or away from the drain channel 410 to close or open the drain mechanism 400. In other embodiments, the closing part 420 of the drain mechanism 400 may be fixed in the electrical device 1, and the drain channel 410 may move toward or away from the closing part 420 to close or open the drain mechanism 400. For example, the cleaning assembly 10 may also include a receiving cavity for accommodating the collection chamber 200 and the roller 100, and a moving mechanism for moving the collection chamber 200. The closing part 420 is fixed to the inner wall of the receiving cavity, and the collection chamber 200 is configured to move between a first position and a second position under the drive of the moving mechanism. When the collection chamber 200 is in the first position, the closing part 420 closes the drain channel 410, and when the collection chamber 200 is in the second position, the closing part 420 is spaced apart from the liquid outlet 412.

[0055] The following will combine Figure 4 and Figure 5 This describes the solution for fixing the closing part 420. Figure 4 A schematic cross-sectional view of the cleaning component 10 according to some embodiments of the present disclosure is shown. Figure 4 As shown, the cleaning assembly 10 includes a roller 100 and a collection chamber 200. The collection chamber 200 includes a scraper 210, a cylindrical portion 220 of the roller, and a roller cover 230. The roller 100 and the collection chamber 200 move together. For example, the roller 100 can be supported between two side walls of the collection chamber 200.

[0056] The cleaning assembly 10 also includes a liquid supply channel 300 formed in the roller cover 230. The cleaning assembly 10 also includes a drain mechanism 400. The drain mechanism 400 communicates with the collection chamber 200 and allows liquid in the collection chamber 200 to drain. Figure 4 As shown, the drainage mechanism 400 includes a drainage channel 410. The drainage channel 410 is fixed to the roller cover 230 and can move with the roller cover 230. Furthermore, the drainage mechanism 400 also includes a closing part 420. The closing part 420 is disposed and fixed on the inner wall 510 of the receiving cavity 500. In some embodiments, the closing part 420 includes a soft rubber capable of covering the liquid outlet. In such embodiments, the soft rubber can cushion the contact with the drainage channel 410 and also provides better closure.

[0057] The cleaning assembly 10 also includes a moving mechanism 600 for moving the collection chamber 200 and the roller 100. The moving mechanism 600 may include a lifting member. The lifting member is capable of raising the collection chamber 200 to a first position to close the drain mechanism 400. The lifting member is also capable of lowering the collection chamber 200 to a second position to allow waste liquid to enter the waste liquid tank 20 from the liquid outlet 412.

[0058] exist Figure 4 In the illustrated embodiment, the lifting member is a rotating lifting member, which includes a rotating shaft 610. The liquid collection chamber 200 and the roller 100 are hinged to the main body of the electrical equipment via the rotating shaft 610, and can rotate around the axis of the rotating shaft 610 between a first position and a second position. In the second position, the roller 100 extends out of the receiving cavity 500 from the bottom and contacts the surface to be cleaned. At this time, the closing part 420 is spaced apart from the drain channel 410, i.e., the drain mechanism 400 is open. Conversely, in the first position, the roller 100 retracts from the bottom into the receiving cavity 500 and no longer contacts the surface to be cleaned. At this time, the closing part 420 contacts the drain channel 410 and covers the liquid outlet of the drain channel 410, i.e., the drain mechanism 400 is closed. Performing self-cleaning operation in this state can prevent the roller 100 from contacting the surface to be cleaned, thereby improving self-cleaning efficiency.

[0059] In some embodiments, the rotating lifting member may include a motor for driving the rotating shaft 610. In such an embodiment, the control unit 50 is able to control the motor to operate the rotation of the rotating shaft 610.

[0060] Figure 5 A schematic cross-sectional view of a cleaning component 10, representing another embodiment of this disclosure, is shown. Figure 5 In the illustrated embodiment, the lifting member is a translational lifting member 620. The liquid collection chamber 200 and the roller 100 are fixed to the main body of the electrical equipment via the translational lifting member 620, and can rotate vertically between a first position and a second position under the drive of the translational lifting member 620. In the second position, the roller 100 extends out of the receiving cavity 500 from the bottom and contacts the surface to be cleaned. At this time, the closing part 420 is spaced apart from the drain channel 410, that is, the drain mechanism 400 is open. Conversely, in the first position, the roller 100 retracts from the bottom into the receiving cavity 500 and no longer contacts the surface to be cleaned. At this time, the closing part 420 contacts the drain channel 410 and covers the liquid outlet of the drain channel 410, that is, the drain mechanism 400 is closed.

[0061] Figure 6 A schematic cross-sectional view of a cleaning component 10 according to yet another embodiment of the present disclosure is shown. Figure 6 In the illustrated embodiment, the cleaning assembly 10 does not include moving parts, and the drainage mechanism is not achieved by opening and closing a drainage channel. Instead, the drainage mechanism 400 of the cleaning assembly 10 includes a pump 430. The pump 430 connects the collection chamber 200 to the waste tank 20. Thus, the pump 430 can be turned on under the control of the control unit 50 to pump liquid from the collection chamber 200 into the waste tank 20. The pump 430 can also be turned off under the control of the control unit 50 to stop pumping. Figure 6 In the illustrated embodiment, the liquid in the collection chamber 200 can be controlled by opening and closing the pump.

[0062] Figure 7 A flowchart of an example self-cleaning method 700 for a cleaning assembly according to some embodiments of the present disclosure is shown. Here, the cleaning assembly may, for example, include a collection chamber for collecting cleaning fluid. A portion of the collection chamber is defined by the cylindrical surface of a roller.
