Description

Technical Field

[0001] The present disclosure relates to a self-cleaning system of a cleaning robot, and a mopping and sweeping system comprising the self-cleaning system and a corresponding cleaning robot. Background Art

[0002] Autonomous mobile devices refer to intelligent mobile devices that can autonomously perform preset tasks. Currently, autonomous mobile devices generally include but are not limited to cleaning robots (such as intelligent sweepers, intelligent floor scrubbers, window cleaning robots), companion mobile robots (such as intelligent electronic pets, nanny robots), service mobile robots (such as reception robots in hotels, inns, and meeting places), industrial inspection intelligent devices (such as power inspection robots, intelligent forklifts, etc.), and security robots (such as home or commercial intelligent guard robots).

[0003] Cleaning robots with dry cleaning components (such as a main brush and a dust box, etc.) and wet cleaning components (such as a rag and a cleaning box, etc.) are increasingly widely used. They can run on the surface to be cleaned and then perform dry cleaning and wet cleaning on the surface to be cleaned. However, after the existing cleaning robots perform cleaning operations on the surface to be cleaned, they need to manually clean the dry cleaning components and the wet cleaning components to clean and remove the dirt collected by the cleaning robots during the cleaning operation. Even if there is a supporting system for automatic cleaning of the cleaning robot, only the dust box of the dry cleaning component is cleaned. In this case, it will be time-consuming and labor-intensive to use manual labor to clean the cleaning robot, and the use of an automated supporting system cannot take into account the simultaneous cleaning of the dry cleaning component and the wet cleaning component.

[0062] The following describes the embodiments of the present disclosure with reference to the accompanying drawings. For ease of understanding, the elements shown in the drawings may include elements whose sizes and scales are different from the actual sizes and scales.

[0063] In the present disclosure, unless otherwise specified, "front (front side)", "rear (rear side)", "left (left side)", "right (right side)", "upper (upper side)", and "lower (lower side)" are all relative to the normal operating state of the cleaning robot in the mopping and sweeping system according to the present disclosure. Specifically, the cleaning robot has a positive direction of motion (i.e., positive direction) when in normal operating state, and the so-called "normal operating state" refers to the moving state of the cleaning robot when performing a task, which is distinguished from the non-normal operating states such as retreat and swing of the cleaning robot in the escape mode. "Front (front side)" and "rear (rear side)" refer to the front and rear sides of the cleaning robot in the positive forward direction when the cleaning robot is in normal operating state on the surface to be cleaned, "left (left side)" and "right (right side)" refer to the left and right sides when viewed from the front side in the positive forward direction, and "upper (upper side)" and "lower (lower side)" refer to the upper and lower sides in the height direction perpendicular to the surface to be cleaned when the cleaning robot is in normal operating state on the surface to be cleaned.

[0064] In the present disclosure, the cleaning robot can move autonomously according to the control scheme preset in its processing unit, and the surface to be cleaned where the cleaning robot moves autonomously can be a plane or a curved surface with a large radius of curvature, typically, for example, the floor in each room in a building. In addition, in the present disclosure, the processing unit is a general term, and the type, quantity and form of the processing unit are not limited. Specifically, the processing unit can be one or more of MCU, DSP, FPGA, GPU, or other types of hardware chips, processors or software algorithms with data processing and computing capabilities. Further, the processing unit can be a unified and unique processor of the cleaning robot, or it can be a collection of multiple processing units, and the connection mode, function and computing power distribution of multiple processing units can be adjusted as needed. For example, in an optional scheme, a first processing unit and a second processing unit can be included. In this case, the first processing unit and the second processing unit as a whole realize the various functions of the above-mentioned processing units. In addition, the processing unit of the cleaning robot of the present disclosure can receive parameters from the sensing component, and can perform relevant control on the cleaning robot through a preset program stored in a storage unit. In the present disclosure, the data, information, and programs required by the processing unit during the processing process can be stored in the storage unit and obtained from the storage unit as needed. The processing unit can store the processed data, information, etc. in the storage unit again. The storage unit can be a RAM, ROM, etc., or a device and / or equipment with storage function such as a cloud / server / mobile terminal connected via a wired / wireless network.

[0065] The mopping and sweeping system according to the first embodiment of the present disclosure is described below in conjunction with the accompanying drawings.

[0066] like Figures 1A to 1E As shown, the mopping and sweeping system according to the first embodiment of the present disclosure includes a cleaning robot MS and a self-cleaning system AC. After cleaning the surface to be cleaned, the cleaning robot MS can autonomously move to the position where the self-cleaning system AC is located and dock to the self-cleaning system AC in a predetermined posture, so that the self-cleaning system AC can automatically clean the dry and wet dirt of the cleaning robot MS at the same time.

[0067] In this embodiment, if Figures 1A to 1E As shown, the self-cleaning system AC of the mopping and sweeping system according to the first embodiment of the present disclosure includes a suction device 1, a first passage 2, a second passage 3, a first collecting container 4, a second collecting container 5, a cleaning component 6 and a selection valve 7 assembled together.

[0068] In this embodiment, if Figures 1A to 1CAs shown, the suction device 1 may include a motor and a suction pump connected in a transmission manner. When the motor is powered on, it can drive the suction pump to perform a suction operation, and a typical example of the suction pump is a vacuum pump.

[0069] In this embodiment, if Figures 1A to 1C As shown, the first passage 2 can be formed by a pipe with a rectangular cross-section through multiple bends. The first end of the first passage 2 is connected to the suction device 1, and the second end of the first passage 2 is formed as a first interface 2p, which is used to be connected to the exhaust port of the dust box 8 of the cleaning robot MS. Further, the first passage 2 includes a first suction pipeline 21 and a first connecting pipeline 22, the first end of the first suction pipeline 21 (that is, the first end of the first passage 2) is connected to the suction device 1 and the second end is connected to the first shell 41 of the first collecting container 4. The first end of the first connecting pipeline 22 is connected to the first shell 41 of the first collecting container 4 and the second end (that is, the second end of the first passage 2) is formed as a first interface 2p. The first suction pipeline 21 and the first connecting pipeline 22 are both connected to the first shell 41 of the first collecting container 4, so that the opening of the second end of the first suction pipeline 21 and the opening of the first end of the first connecting pipeline 22 are configured in a manner separated by the first filter 42 of the first collecting container 4. In this way, not only the first suction pipeline 21 and the first connecting pipeline 22 are connected to each other via the first collecting container 4, but also all dry dirt in the airflow flowing through the first collecting container 4 is collected into the first collecting container 4. When the suction device 1 is working, under the action of the selection valve 7, negative pressure is generated in the first suction pipeline 21, the first connecting pipeline 22, the first collecting container 4 and the dust box 8. The waste in the dust box 8 is sucked into the first shell 41 of the first collecting container 4, and is intercepted by the first filter 42 and remains in the first shell 41.

[0070] Furthermore, if Figure 1B and Figure 1CAs shown, at a portion of the first suction pipeline 21 close to the suction device 1, the side wall of the first passage 2 is formed with a first sealed portion 2s protruding toward the inside of the first passage 2. When the first passage 2 is closed, the selection valve 7 is driven so that the first sealing portion 71 abuts against the first sealed portion 2s, and then the first sealing portion 71 further abuts against the first sealed portion 2s through the suction of the suction device 1. Thus, when the first passage 2 is closed, the suction effect of the suction device 1 is used to form a negative pressure inside the passage, and further the first sealing portion 71 and the first sealed portion 2s are more tightly abutted to form a better sealing state, thereby enabling the first passage 2 to be more reliably closed. Similarly, when the second passage 3 is closed, the suction effect of the suction device 1 is used to form a negative pressure inside the passage, and further the second sealing portion 72 and the second sealed portion 3s are more tightly abutted to form a better sealing state, thereby enabling the second passage 3 to be more reliably closed.

[0071] In this embodiment, if Figures 1A to 1C As shown, the second passage 3 can be formed by a pipe with a rectangular cross-section through multiple bends. The first end of the second passage 3 is connected to the suction device 1, and the second end of the second passage 3 is formed as a second interface 3p, and the second interface 3p is connected to the suction port 621o of the tray 62 of the cleaning assembly 6, so that the suction device 1 can be used to perform suction through the suction port 621o. Further, the second passage 3 includes a second suction pipeline 31 and a second connecting pipeline 32, the first end of the second suction pipeline 31 (that is, the first end of the second passage 3) is connected to the suction device 1 and the second end extends into the second shell 51 of the second collecting container 5, the first end of the second connecting pipeline 32 extends into the second shell 51 of the second collecting container 5 and the second end (that is, the second end of the second passage 3) is formed as a second interface 3p. As shown Figure 1B and Figure 1CAs shown, the opening of the second end of the second suction pipeline 31 and the opening of the first end of the second connecting pipeline 32 are open in opposite directions, and the opening of the second end of the second suction pipeline 31 and the opening of the first end of the second connecting pipeline 32 are always located at a position higher than the liquid level in the second shell 51, and the opening of the second end of the second suction pipeline 31 is always located at a position higher than the opening of the first end of the second connecting pipeline 32. During the suction process, since the opening (inlet) of the second end of the second suction pipeline 31 is higher, it is not easy for water vapor to enter the suction device 1 from the opening. Therefore, the greater the difference in height between the openings of the second suction pipeline 31 and the second connecting pipeline 32 in the second shell 51, the better the effect. In addition, the second filter 52 of the second collection container 5 is arranged in the second suction pipeline 31. In this way, not only the second suction pipeline 31 and the second connecting pipeline 32 are connected to each other via the second collecting container 5, but also all wet dirt in the airflow flowing through the second collecting container 5 is collected into the second collecting container 5, and wet dirt and excessive humid air can be fully prevented from entering the second suction pipeline 31, thereby reducing the risk of failure of the suction device 1. When the suction device 1 is working, under the action of the selection valve 7, negative pressure is generated in the second suction pipeline 31, the second connecting pipeline 32, the second collecting container 5 and the cleaning assembly 6. The waste of the wet cleaning element 9 is sucked into the second housing 51 of the second collecting container 5, and is intercepted by the second filter 52 and remains in the second housing 51.

[0072] Furthermore, if Figure 1B and Figure 1C As shown, at a portion of the second suction pipeline 31 close to the suction device 1, the side wall of the second passage 3 is formed with a second sealed portion 3s protruding toward the inside of the second passage 3. When the second passage 3 is closed, the selection valve 7 is driven so that the second sealing portion 72 abuts against the second sealed portion 3s, and then the second sealing portion 72 further abuts against the second sealed portion 3s through the suction of the suction device 1. Thus, when the second passage 3 is closed, the suction effect of the suction device 1 is used to form a negative pressure inside the passage, further causing the second sealing portion 72 to abut more tightly against the second sealed portion 3s to form a better sealing state, thereby enabling the second passage 3 to be more reliably closed. Similarly, when the first passage 2 is closed, the suction effect of the suction device 1 is used to form a negative pressure inside the passage, further causing the first sealing portion 71 to abut more tightly against the first sealed portion 2s to form a better sealing state, thereby enabling the first passage 2 to be more reliably closed.

[0073] In this embodiment, if Figures 1A to 1CAs shown, the first collection container 4 is used to collect dry dirt and is arranged in the first passage 2. The airflow entering the first passage 2 through the first interface 2p flows through the first collection container 4 by suction of the suction device 1. The first collection container 4 includes a first shell 41 and a first filter 42. The first filter 42 may be a filter net capable of collecting dry dirt such as fine dust and hair, and the first filter 42 is arranged in the first shell 41 and the shape and size of the first filter 42 are configured to match the shape and size of the cross section of the first shell 41. As described above, the first suction line 21 and the second suction line 31 of the first passage 2 are both connected to the first shell 41 of the first collection container 4, and the opening of the second end of the first suction line 21 and the opening of the first end of the first connecting line 22 are configured in a manner separated by the first filter 42. As a result, all dry dirt in the airflow flowing through the first collection container 4 can be collected into the first shell 41 of the first collection container 4 mainly by using the first filter 42.

[0074] In this embodiment, if Figures 1A to 1C As shown, the second collecting container 5 is used to collect wet dirt and is arranged in the second passage 3. The airflow entering the second passage 3 through the second interface 3p flows through the second collecting container 5 by the suction of the suction device 1. The second collecting container 5 includes a second shell 51 and a second filter 52. The second filter 52 can be a sponge block, and the second filter 52 mainly prevents wet dirt and excessive humid air from entering the suction device 1 through the second passage 3. The second filter 52 is not only arranged in the second shell 51, but also filled in the second suction pipeline 31. Further, in conjunction with the relative positional relationship between the second end of the second suction pipeline 31 and the first end of the second connecting pipeline 32 described above, all wet dirt in the airflow flowing through the second collecting container 5 can be collected in the second shell 51 of the second collecting container 5, which is conducive to the wet dirt and sewage entering the second collecting container 5 settling to the bottom, reducing the risk of them being sucked into the second suction pipeline 31.

[0075] In this embodiment, if Figure 1A , Figure 1D and Figure 1E As shown, the cleaning assembly 6 includes a base 61, a tray 62 and a power assembly, and the tray 62 is arranged on the base 61 in a manner that it can move relative to the base 61 through the power assembly. The tray 62 is formed with a suction port 621o connected to the second interface 3p of the second passage 3, so that the suction device 1 can perform suction through the suction port 621o.

[0076] like Figure 1D and Figure 1EAs shown, the base 61 is formed into a concave shape that is open toward the upper side. The tray 62 has a first top wall 621, a first bottom wall 622, and a first side wall 623, and the first top wall 621, the first bottom wall 622, and the first side wall 623 surround and form a hollow cavity. When the self-cleaning system AC is placed on a horizontal plane and installed in place, the first top wall 621 is arranged along the horizontal plane. Figure 1F , a plurality of suction ports 621o are formed in the first top wall 621, and the plurality of suction ports 621o are arranged in an array on the first top wall 621, and the overall shape formed by the array may be similar to the shape of the wet cleaning member 9. The second interface 3p of the second passage 3 is connected to the internal space of the tray 62 via the interface formed by the first side wall 623, so that the suction device can provide negative pressure to the suction port 621o via the second interface 3p, the interface of the first side wall 623, and the internal space of the tray 62. In this way, the wet dirt sucked from the wet cleaning member 9 can be smoothly sucked into the second passage 3 via the suction port 621o, the internal space of the tray 62, the interface of the first side wall 623, and the second interface 3p, and then enter the second collection container 5. In addition, the first bottom wall 622 is arranged tilted toward the second interface 3p relative to the horizontal plane, which can minimize the probability of the generated sewage remaining in the hollow cavity of the tray 62.

[0077] like Figure 1D and Figure 1E As shown, the power assembly includes a power source, a lead screw 63 and a nut 64. The power source can be a driving motor. The lead screw 63 is mounted on the base 61 and can rotate relative to the base 61, and the nut 64 is fixed to the first bottom wall 623 of the tray 62 and is threadedly connected with the lead screw 63. The power source can drive the lead screw 63 to rotate, so that the nut 64 drives the tray 62 to perform reciprocating linear relative motion relative to the base 61. It can be understood that the lead screw 63 with different lead pitches can be selected as needed, so that the relative motion relationship between the rotation of the lead screw 63 and the nut 64 can be adjusted. Thus, the wet cleaning member can perform stable reciprocating linear motion relative to the base 61 with a relatively simple structure, so that the suction port 621o and the wet cleaning member 9 produce relative motion. In this way, the suction port 621o can be opposite to as many parts of the wet cleaning member 9 as possible, thereby improving the cleaning effect of the wet cleaning member 9. At the same time, the edge of the suction port 621o and the wet cleaning member 9 can scrape left and right, which can also enhance the cleaning of the wet cleaning member 9 such as a mop from a physical effect.

[0078] In this embodiment, the cleaning component 6 having the above-mentioned structure is conducive to the adaptation of the self-cleaning system AC to the wet cleaning element 9 of the cleaning robot MS, such as a flat rag, and the suction effect of the suction device 1 can clean the dirt on the flat rag as fully as possible.

[0079] In another embodiment, the wet cleaning parts on some cleaning robots (mopping machines) can utilize the structure of the cleaning robot itself to achieve vibration to enhance the mopping effect. In this case, the power component can be omitted based on the above embodiment and only a fixed tray is required to clean the wet cleaning parts.

[0080] In this embodiment, if Figure 1A and Figure 1B As shown, the selection valve 7 is arranged in the first passage 2 and the second passage 3, and is used to selectively connect the first passage 2 and the second passage 3 in a selective manner or to connect the first passage 2 and the second passage 3 at the same time. Further, the selection valve 7 is installed in the first passage 2 and the second passage 3 and can rotate relative to the first passage 2 and the second passage 3, and the selection valve 7 includes a first sealing portion 71 and a second sealing portion 72. During the rotation of the selection valve 7, the first sealing portion 71 can abut against the first sealed portion 2s in the first passage 2 to close the first passage 2, and the second sealing portion 72 can abut against the second sealed portion 3s in the second passage 3 to close the second passage 3. Therefore, in addition to the mode of simultaneously realizing the suction of dry waste and wet waste (the selection valve 7 does not close the first passage 2 or the second passage 3), when only one of the first passage 2 and the second passage 3 is connected, the suction of dry waste and wet waste can be realized in a selective manner. In addition, when the suction effect of the suction device 1 acts only on a single passage, a motor with a smaller power can be used to better close one passage and form a larger negative pressure in the other passage. In this way, a suction device 1 with lower power can achieve an ideal suction cleaning effect, which is conducive to further reducing the cost of the suction device 1 and the entire system. Moreover, realizing multiple working modes through one suction device 1 can simplify the system structure and reduce costs.

[0081] By adopting the above scheme, when the dust box 8 of the cleaning robot MS is connected to the first interface 2p and the wet cleaning member 9 such as a rag is placed on the cleaning assembly 6, the same suction device 1 can be used to suck dry dirt such as dust in the dust box 8 into the first collection container 4, thereby cleaning the dust box 8; on the other hand, wet dirt such as a mixture of dust and water attached to the wet cleaning member 9 can be sucked into the second collection container 5, thereby cleaning the wet cleaning member 9 and making the wet cleaning member 9 dry faster. Thus, a self-cleaning system AC with a simple structure and low cost for automatically cleaning dry and wet dirt is realized.

[0082] In this embodiment, if Figure 1A , Figure 1D and Figure 1EAs shown, the cleaning robot MS of the mopping and sweeping system according to the first embodiment of the present disclosure is a self-moving cleaning device having a dry cleaning component and a wet cleaning component. The cleaning robot MS includes a main body, a wheel component, a dry cleaning component and a wet cleaning component assembled together.

[0083] In this embodiment, the main body may include a housing having a generally cylindrical shape as a whole. The shape of the housing is not limited thereto, and in other optional schemes, the housing may also have other shapes, such as a D-shape, an ellipse, a square, etc. When the cleaning robot MS is in a normal operating state, the bottom surface of the housing is opposite to the surface to be cleaned, and the bottom surface of the housing is parallel to the surface to be cleaned. Here, "parallel" not only includes that the bottom surface of the housing and the surface to be cleaned have a geometric parallel relationship, but also includes the situation that the two are roughly parallel. The above "roughly" means that within the reasonable error range recognized by those skilled in the art, it can be determined that the parallel relationship between the two is established. In addition, other components of the cleaning robot MS can be arranged in the housing, and in order to support and protect other components, most of the structures of the cleaning robot MS are installed inside or on the surface of the housing, or have a connection relationship with the housing. The cleaning robot MS may also be provided with a processing unit and a sensing component in the housing. The processing unit can obtain environmental parameters through the sensing component, and the processing unit can control the wheel component to drive the entire autonomous mobile device to move autonomously on the surface to be cleaned based on the environmental parameters obtained, and then in this process, the dry cleaning component and the wet cleaning component are used to clean the surface to be cleaned. In different working modes, cleaning operations include but are not limited to one or more of sweeping, mopping, vacuuming, and the like.

[0084] Further, the two wheel assemblies are located at the left and right sides of the main body and arranged side by side, and the two wheel assemblies are located in the middle of the main body in the front-to-back direction. Each wheel assembly may include a travel motor and a wheel assembled together. The wheel axle of the wheel is connected to the travel motor in a transmission manner so that the torque from the travel motor can be transmitted to the wheel via the reduction mechanism to drive the wheel to rotate with the wheel axle as the rotation center. It can be understood that the wheel always extends relative to the bottom surface of the housing so as to roll in contact with the surface to be cleaned, so that the wheel assembly can drive the entire cleaning robot MS to move on the surface to be cleaned under the control of the processing unit. In addition, by rotating the wheels (main drive wheels) of the two wheel assemblies in the same direction at the same speed (for example, rotating clockwise or counterclockwise at the same time), the autonomous mobile device can be driven to move in a straight line along the forward direction; by rotating the drive wheels of the two wheel assemblies at different speeds and / or different directions (for example, one drive wheel rotates clockwise and the other drive wheel rotates counterclockwise), the cleaning robot MS can be driven to turn in a direction different from the forward direction. In addition, the cleaning robot MS is also provided with universal wheels, so no matter how the driving wheels roll on the surface to be cleaned, the universal wheels can support the entire autonomous moving device.

[0085] Furthermore, if Figure 1D and Figure 1E As shown, the dry cleaning assembly includes a dust box 8. The dust box 8 is formed with a first docking interface, and the first docking interface can be communicated with the first interface 2p. Thus, the dust box 8 is sucked by the suction device 1 via the first interface 2p and the first docking interface, and then the dry dirt is sucked and collected into the first collection container 4. The wet cleaning assembly includes a wet cleaning member 9 such as a rag and a cleaning box 10, and the wet cleaning member 9 is located at the bottom of the dust box 8 and the wet cleaning member 9 can be cleaned by the cleaning assembly 6. The cleaning box 10 can accommodate a cleaning fluid and the cleaning box 10 is formed with a drain port corresponding to the wet cleaning member 9, thereby supplying the cleaning fluid to the rag. Thus, the wet cleaning assembly is sucked by the suction device 1 via the cleaning assembly 6, and then the wet dirt is sucked and collected into the second collection container 5, and the wet cleaning member 9 can be dried faster.

[0086] The mopping and sweeping system according to the second embodiment of the present disclosure is described below with reference to the accompanying drawings.

[0087] like FIG. 2A to FIG. 2C As shown, the structure of the mopping and sweeping system according to the second embodiment of the present disclosure is substantially the same as the structure of the mopping and sweeping system according to the first embodiment of the present disclosure, and the differences between the two are mainly described below.

[0088] In this embodiment, if FIG. 2A to FIG. 2CAs shown, the cleaning assembly 6' includes a base 61', and the base 61' is connected to the second interface 3p. The base 61' is formed with two circular grooves 611c', and the base 61 is formed with a suction port 611o1' at the bottom of each groove 611c', so that the suction device 1 can be used to suck through the suction port 611o1'. The base 61' is formed with an injection port 611o2' at the bottom of the groove 611c', and the base 61' can supply a cleaning fluid through the injection port 611o2'.

[0089] Furthermore, if Figure 2C As shown, the base 61' has a second top wall 611', a second bottom wall 612' and a second side wall 613', and the second top wall 611', the second bottom wall 612' and the second side wall 613' surround and form a hollow cavity. The above-mentioned groove 611c', the suction port 611o1' and the injection port 611o2' are formed on the second top wall 611'. When the self-cleaning system AC is placed on a horizontal plane and installed in place, the second top wall 611' is arranged along the horizontal plane, the second interface 3p is connected to the hollow cavity of the base 61' via the interface of the second side wall 613', and the suction device 1 is connected to the suction port 611o1' via the second interface 3p, the interface of the second side wall 613' and the hollow cavity of the base 61', thereby providing negative pressure for the suction port 621o. In addition, the second bottom wall 612' is arranged tilted toward the second interface 3p relative to the horizontal plane. By adopting the above solution, the wet dirt sucked from the wet cleaning member 9 can be smoothly sucked into the second passage 3 through the suction port 611o1', the internal space of the base 61', the interface of the second side wall 613' and the second interface 3p, and then enter the second collection container 5. In addition, the probability of the generated sewage remaining in the hollow cavity of the base 61' can be reduced as much as possible.

[0090] Furthermore, if Figure 2C As shown, the second side wall 613' is also formed with an inlet 613o' for the cleaning fluid to enter, and the cleaning fluid entering the base 61' through the inlet 613o' can reach the injection port 611o2' after passing through a predetermined flow path. In addition, by utilizing the function of the cleaning robot MS itself, the wet cleaning member 9 can be rotated in the groove 611c', so that all parts of the wet cleaning member 9 can be opposite to the suction port 611o1' and the injection port 611o2'.

[0091] By adopting the above solution, the self-cleaning system AC is advantageously adapted to other types of wet cleaning parts 9 of the cleaning robot MS, such as a rotating rag, and the suction effect of the suction device 1 can clean the wet dirt of the wet cleaning part 9 in the groove 611c' as fully as possible.

[0092] It should be understood that the above embodiments are merely exemplary and are not intended to limit the present disclosure. Those skilled in the art may make various modifications and changes to the above embodiments under the guidance of the present disclosure without departing from the scope of the present disclosure. The following supplementary explanation is provided for the technical solution of the present disclosure.

[0093] i. It can be understood that in order to facilitate the arrangement of the selection valve 7 in the first passage 2 and the second passage 3, a common part of the two passages 2 and 3 is formed at the position of the first passage 2 and the second passage 3 close to the suction device 1, and the first passage 2 and the second passage 3 are connected to each other at the common part. The selection valve 7 can be driven by an additional motor to achieve different gears, so that the first passage 2 and the second passage 3 can achieve different conduction states as described above. In other variations, the first passage 2 and the second passage 3 may not form a common part, that is, the first passage 2 and the second passage 3 are independent of each other. Correspondingly, the selection valve 7 can be arranged in the first passage 2 and the second passage 3 in the form of a component. For example, the selection valve 7 may include a first valve core extending into the first passage 2 and a second valve core extending into the second passage 3. The same effect can be achieved by controlling the first valve core and the second valve core.

[0094] ii. In a variation of the first embodiment, the number of the plurality of suction ports 621o and the arrangement of the array can be adjusted as needed so that the plurality of suction ports 621o can be opposite to as many parts of the wet cleaning element 9 as possible during the relative movement of the tray 62 relative to the base.

[0095] iii. In a variation of the first embodiment, the tray 62 may be formed with a plurality of limiting posts, thereby being able to limit the relative movement range of the tray 62 relative to the base.
