Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a cleaning robot and cleaning system. Background Technology

[0002] Currently, in most homes, carpets and other fabric products are commonly used on the floor. While these fabric products can enhance the comfort and aesthetics of the living environment, they also easily trap dirt, bacteria, and other pollutants, leading to unpleasant odors. Therefore, these fabric products require users to actively clean them after a period of use.

[0003] Traditional cleaning methods mainly rely on manual washing by users, which is not only time-consuming and laborious, but also often yields unsatisfactory cleaning results. Therefore, how to clean fabric products efficiently and conveniently has become an urgent problem to be solved. Summary of the Invention

[0004] This application provides a cleaning robot and cleaning system that can automatically clean fabric products, saving time and effort while achieving good cleaning results.

[0006] Secondly, this application also provides a cleaning system, comprising:

[0007] Such as any of the cleaning robots mentioned above; and

[0008] A base station is used to interface with the cleaning robot and to charge the cleaning robot.

[0009] The beneficial effects of this application are as follows: the cleaning robot can perform wet cleaning of fabric products. When the cleaning robot is on the surface of the fabric product, it sprays the cleaning liquid in the clean water chamber onto the fabric product through the spray nozzle, so that the cleaning liquid mixes with the dirt on the fabric product. The suction component can provide suction to the suction port to suck the dirt into the wastewater chamber. As the cleaning robot moves on the surface of the fabric product, it can perform a comprehensive wet cleaning of the fabric product, ensuring the cleaning effect of the fabric product. Moreover, the whole process does not require user intervention, saving time and effort. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0033] This application provides a cleaning robot, specifically, such as Figure 1 and Figure 2As shown, the cleaning robot includes a body 10 and drive wheels 12. The drive wheels 12 are located at the bottom of the body 10 and are used to drive the body 10 to move. It can be understood that the body 10 is the main structure of the cleaning robot, providing installation space and support for components such as the drive wheels 12. The body 10 can be disc-shaped, square-shaped, or other shapes, and the outer shell of the body 10 can be made of plastic, metal, or other materials. The drive wheels 12 are the walking wheels of the cleaning robot. When the cleaning robot moves, the drive wheels 12 provide driving force, enabling the cleaning robot to move automatically without requiring manual pushing from the user.

[0034] More specifically, such as Figure 2 and Figure 3 As shown, the cleaning robot also includes a cloth wet cleaning component 30, a water tank component 50, and a suction component 60.

[0035] The fabric wet cleaning component 30 is connected to the main body 10. The fabric wet cleaning component 30 is used for wet cleaning of fabric products and has a spray nozzle 321 and a suction port 322. The water tank component 50 has a clean water chamber and a wastewater chamber 51 that are separated from each other (e.g., ...). Figure 15 The clean water chamber is connected to the spray hole 321, and the sewage chamber 51 is connected to the suction port 322. The clean water chamber is used to store clean water or a mixture of clean water and detergent, etc. The sewage chamber 51 can be used to temporarily store liquid waste, such as urine, sewage, etc., or mixed wet and dry waste. The suction assembly 60 includes a suction source 61 installed on the body 10. The suction source 61 is used to communicate with the sewage chamber 51 so that the waste can be sucked from the suction port 322 into the sewage chamber 51. The suction source 61 can be a fan or pump or other device that can provide suction to the suction port 322.

[0036] It is worth mentioning that the fabric products in this application mainly refer to soft decorative items laid on the ground, such as carpets and floor mats. For these types of fabric products, the cleaning robot can automatically walk onto the surface of the fabric product. In other embodiments, fabric products may also include items that are at a certain height from the ground, such as fabric sofas and mattresses. For these types of fabric products, the cleaning robot can climb onto the surface of the fabric product by itself using a climbing structure or the user can carry it to the surface of the fabric product.

[0037] The cleaning robot of this application can perform wet cleaning of fabric products. When the cleaning robot is on the surface of the fabric product, it sprays the cleaning liquid in the clean water chamber onto the fabric product through the spray nozzle 321, so that the cleaning liquid mixes with the dirt on the fabric product. The suction component 60 can provide suction to the suction port 322 to suck the dirt into the wastewater chamber 51 through the suction port 322. As the cleaning robot moves on the surface of the fabric product, it can perform a comprehensive wet cleaning of the fabric product, ensuring the cleaning effect of the fabric product. Moreover, the whole process does not require user intervention, saving time and effort.

[0038] In one embodiment, the cloth wet cleaning component 30 is detachably connected to the body 10. The cleaning robot also includes a mopping component detachably connected to the body 10. The body 10 has a first mounting area for mounting either the cloth wet cleaning component 30 or the mopping component. As the name suggests, the mopping component is used for cleaning floors, primarily for hard surfaces such as wooden floors, tiles, or marble. In this embodiment, the cloth wet cleaning component 30 and the mopping component are interchangeable, but they share the same mounting area. When the cloth wet cleaning component 30 is needed, it is installed in the first mounting area, at which point the mopping component is detached. When the mopping component needs to be used, the cloth wet cleaning component 30 is detached from the body 10, and then the mopping component can be installed in the first mounting area.

[0039] In another embodiment, the cleaning robot can simultaneously install a mopping component and a cloth wet cleaning component 30. Specifically, the body 10 has a first installation area and a second installation area. The first installation area is used to install the cloth wet cleaning component 30, and the second installation area is used to install the mopping component. The first installation area can be located in front of or behind the second installation area. It is understood that in this embodiment, the cloth wet cleaning component 30 and the mopping component are two independent components, and their installation areas are different. When the cloth wet cleaning component 30 is needed, it is installed in the first installation area. At this time, the mopping component can be either detached or installed. When the mopping component is installed, it can be controlled to be in a non-working state. When the mopping component is needed, it is installed in the second installation area. At this time, the cloth wet cleaning component 30 can be either detached or installed. When the cloth wet cleaning component 30 is installed, it can be controlled to be in a non-working state. Of course, in some embodiments, the mopping component may be omitted, depending on the application scenario of the cleaning robot.

[0040] In one embodiment of this application, the mopping assembly includes a roller for rotatable connection with the main body 10. The axis of the roller extends along the left-right direction of the cleaning robot. The mopping assembly has a liquid outlet and a liquid inlet. The liquid outlet communicates with a clean water chamber, the roller receives clean water output from the liquid outlet, and the liquid inlet communicates with a wastewater chamber. A suction source is also used to draw debris from the liquid inlet into the wastewater chamber. It is understood that the roller can rotate relative to the main body to clean the floor. The liquid outlet can communicate with the clean water chamber. During mopping, the liquid outlet can output clean water to the roller, and the liquid inlet draws debris into the wastewater chamber. In this embodiment, the mopping assembly and the cloth wet cleaning assembly 30 share the water tank assembly 50 and the suction source 61 to simplify the structure of the cleaning robot and reduce its overall size. In other embodiments, the mopping assembly may also be configured with a separate water tank assembly and suction source.

[0041] In addition, in some embodiments, the mopping assembly may also adopt other mop structures, such as a rotating mop that is rotatably connected to the body and whose rotation axis is perpendicular to the ground, or a flat fan-shaped mop. In these embodiments, the liquid inlet of the mopping assembly may be omitted.

[0042] In some embodiments of this application, the cleaning robot may further include a dry cleaning component 20, which is disposed at the bottom of the body 10 and connected to the body. As the name suggests, the dry cleaning component 20 is a component used for dry cleaning of the surface to be cleaned. The surface to be cleaned can be the hard floor mentioned above, or the fabric product mentioned above. It is understood that in this embodiment, the cleaning robot has at least two cleaning states: a dry cleaning state and a fabric cleaning state. When the cleaning robot is in the dry cleaning state, it can use the dry cleaning component 20 for cleaning; when the cleaning robot is in the fabric cleaning state, it can use the fabric wet cleaning component 30, or use both the fabric wet cleaning component 30 and the dry cleaning component 20 for cleaning, so that the cleaning robot can be applied to more cleaning scenarios.

[0043] The dry cleaning component 20 can be arranged in front of the fabric wet cleaning component 30. It should be noted that, in the cleaning robot's direction of travel XX, the cleaning robot typically has a head (or front part) and a tail (or rear part). The forward direction of the cleaning robot is from the tail to the head, and the backward direction is from the head to the tail. The dry cleaning component 20 is arranged in front of the fabric wet cleaning component 30, meaning the direction from the fabric wet cleaning component 30 to the dry cleaning component 20 is parallel to the cleaning robot's forward direction. When the cleaning robot moves in the forward direction to clean fabric products, it can first use the dry cleaning component 20 to perform dry cleaning, removing some of the debris, and then use the fabric wet cleaning component 30 to perform wet cleaning, which can further improve the cleaning effect of the carpet. Of course, in other embodiments, the dry cleaning component 20 can also be omitted, depending on the actual functional requirements of the cleaning robot.

[0044] In one embodiment, the fabric wet cleaning assembly 30 includes a fabric cleaning component 31, which is either a first roller brush or a first flat brush. The first roller brush is rotatably connected to the machine body, and the first flat brush is fixed relative to the machine body. It is understood that when using the first roller brush, it is located at the bottom of the machine body and can rotate relative to the machine body. The first roller brush can be a brush with bristles or a rubber roller brush without bristles. When using the first flat brush, it is fixed to the bottom of the machine body and can have bristles or a rubber brush strip. In this embodiment, it should be explained that the fabric wet cleaning assembly 30 may include both a first roller brush and a first flat brush, with one of them connected to the machine body depending on the type of fabric product. In other embodiments, the fabric wet cleaning assembly 30 may consist of only one of the first roller brush and the first flat brush; no specific limitation is made here.

[0045] In one embodiment, the dry cleaning component 20 includes a dry cleaning element 21 rotatably connected to the main body, and the fabric cleaning element 31 includes a first bristle 311 and a second bristle. The first bristle 311 has a higher hardness than the second bristle. It is understood that both the dry cleaning component 20 and the fabric cleaning element 31 have bristles. The first bristle 311 of the fabric cleaning element 31 is made of a harder material, giving it good friction and poor water absorption. When the cleaning robot walks on the surface of fabric products, the fabric cleaning element 31 can vigorously rub against the surface of the fabric product, causing dirt to separate from the fabric product. This makes it easier for the dirt to be sucked into the wastewater chamber 51. Especially for carpets with a certain thickness of pile, the first bristle 311 of the fabric cleaning element 31 can penetrate into the pile to clean out dirt deep within the carpet. Meanwhile, the first brush bristles 311, made of a stiffer material, do not easily adhere to liquids and dirt, preventing secondary contamination of the carpet when the fabric cleaning unit 31 cleans the carpet, and also reducing the frequency of washing the fabric cleaning unit 31 by the user. The second brush bristles of the dry cleaning unit 21 are made of a softer material, which can prevent the dry cleaning unit 21 from scratching hard surfaces when cleaning hard surfaces.

[0046] It is worth mentioning that in other embodiments, the dry cleaning component 21 may also be a rubber roller brush without bristles, or the dry cleaning component 21 may be omitted, and the dry cleaning assembly 20 sucks in dry waste through a suction port formed at the bottom of the body.

[0047] Furthermore, the length of the fabric cleaning component 31 is greater than the length of the dry cleaning component 21, giving the fabric cleaning component 31 a larger cleaning area and improving carpet cleaning efficiency. The length of the fabric cleaning component 31 refers to its length in the left-right direction of the cleaning robot; the same applies to the length of the dry cleaning component 21. Moreover, the drive wheel 12 is located between the dry cleaning component 21 and the fabric cleaning component 31, increasing the distance between them and preventing interference. This also keeps the robot's center of gravity closer to the middle, preventing it from tilting its head or tail.

[0048] In one embodiment, the fabric cleaning component 31 is located between the spray nozzle 321 and the suction port 322, with the spray nozzle 321 positioned in front of the fabric cleaning component 31. This allows the cleaning robot to first spray water through the spray nozzle 321, then clean the fabric using the fabric cleaning component 31, and finally suck the debris into the wastewater chamber 51 through the suction port 322 when it moves forward to clean the fabric. It is easy to understand that for a cleaning robot that omits the fabric cleaning component 31, the spray nozzle 321 is located in front of the suction port 322.

[0049] In some embodiments of this application, the fuselage has a dust collection chamber 41 (e.g., Figure 12 The system includes a suction port 11 connected to the dust collection chamber 41; the suction source 61 is also connected to the dust collection chamber 41 to draw debris from the suction port 11 into the dust collection chamber 41. It is understood that in this embodiment, the suction source 61 can be a fan. When the cleaning robot is in dry cleaning mode, the suction source 61 can also provide suction to the suction port 11, drawing dry debris from the ground into the dust collection chamber 41. One suction source 61 can meet the suction requirements of both the suction port 11 and the dirt suction port 322, thus enabling the cleaning robot to perform dirt suction in both dry cleaning and fabric cleaning modes. This reduces the number of suction sources 61 in the cleaning robot, thereby reducing the production cost and overall size of the cleaning robot. Of course, in other embodiments, a separate fan for dry cleaning can be configured.

[0050] In one embodiment, the cleaning robot may further include a dust collection box 40, which is detachably mounted on the body 10. The dust collection box 40 has a dust collection chamber 41. When the dust collection chamber needs to be cleaned, the dust collection box 40 can be disassembled for cleaning, making the cleaning of the dust collection chamber more convenient. In other embodiments, the dust collection chamber 41 can also be directly formed inside the body 10 by setting a partition or other structure inside the body 10.

[0051] like Figure 3 As shown, the body 10 may include a body 13, a cover 14 and a face cover 15. The dry cleaning component 20 and the cloth wet cleaning component 30 are installed at the bottom of the body 13. The cover 14 is placed on the body 13. The dust collection box 40, the suction component 60 and the water tank component 50 are all installed in the space formed by the connection between the body 13 and the cover 14. The face cover 15 is stacked on the cover 14 to serve a decorative and protective function.

[0052] like Figures 3 to 5 As shown, in some embodiments of this application, the dust collection chamber 41 and the water tank assembly 50 are arranged along the traveling direction XX of the cleaning robot, and the suction assembly 60 is located between the dust collection box 40 and the water tank assembly 50, making the arrangement of the dust collection box 40, the water tank assembly 50 and the suction assembly 60 more compact, which can reduce the overall size of the cleaning robot and make the connection between the suction assembly 60 and the dust collection box 40 and the water tank assembly 50 more convenient.

[0053] In this embodiment, the suction source 61 is used to selectively connect to the wastewater chamber 51. It can be understood that when the cleaning robot is in dry cleaning mode, the suction source 61 is connected to the dust collection chamber 41, and at this time, the suction source 61 can be disconnected from the wastewater chamber 51 to increase the suction power at the suction port 11. When the cleaning robot needs to use wet cleaning functions, such as mopping hard floors or wet washing fabric products, the suction source 61 can be connected to the wastewater chamber 51, so that one suction source 61 can meet the suction power requirements for both dry cleaning and wet washing.

[0054] like Figures 6 to 11 As shown, in some embodiments of this application, the suction assembly 60 further includes an air collector 62. The air collector 62 has a ventilation channel 624 and a first air inlet 621, a second air inlet 622 and an air collector 623 connected to the ventilation channel 624. The first air inlet 621 and the second air inlet 622 are both connected to the air collector 623. The first air inlet 621 is connected to the dust collection chamber 41, the second air inlet 622 is selectively connected to the sewage chamber 51, and the air collector 623 is connected to the suction source 61.

[0055] At least when the cleaning robot is in fabric cleaning mode, the second air inlet 622 is connected to the wastewater chamber 51, allowing the suction source 61 to provide suction to the suction port 322 through the wastewater chamber 51. It is understood that the air concentrator 62 connects the suction source 61 to the dust collection box 40 and the water tank assembly 50, allowing the suction source 61 to meet the suction requirements of both the dust suction port 11 and the wastewater suction port 322. When the cleaning robot is in dry cleaning mode, the first air inlet 621 is connected to the dust collection chamber 41. The airflow generated by the suction source 61 passes sequentially through the dust suction port 11, the dust collection chamber 41, the first air inlet 621, the ventilation channel 624, the air concentrator 623, and the suction port 611 of the suction source 61, thus ensuring suction at the dust suction port 11. A negative pressure is generated at point 1, causing the garbage to be sucked into the dust collection chamber 41 through the suction port 11. When the cleaning robot is in the fabric cleaning state, the second air inlet 622 is connected to the sewage chamber 51. The suction source 61 generates two airflows. One airflow flows from the suction port 11 to the suction source 61, and the other airflow passes through the sewage suction port 322, the sewage chamber 51, the second air inlet 622, the ventilation channel 624, the air converging port 623, and the suction port 611 in sequence, thereby generating a negative pressure at the sewage suction port 322, causing the garbage to be sucked into the sewage chamber 51 through the sewage suction port 322.

[0056] See also Figures 6 to 11As shown, in some embodiments of this application, the suction assembly 60 further includes an opening and closing structure 63, which includes an opening and closing plate 631. The opening and closing plate 631 is movably connected to the air collector 62. The opening and closing plate 631 is used to open and close the second air inlet 622 to achieve selective communication between the second air inlet 622 and the sewage chamber 51. It can be understood that the opening and closing of the second air inlet 622 can be controlled by the opening and closing plate 631, thereby realizing the connection and disconnection between the ventilation channel 624 and the sewage chamber 51. When the wet cleaning function is required, the opening and closing plate 631 opens the second air inlet 622, connecting the ventilation channel 624 and the sewage chamber 51; when wet cleaning is not required, the opening and closing plate 631 closes the second air inlet 622, thereby isolating the ventilation channel 624 and the sewage chamber 51.

[0057] In some specific embodiments, when the cleaning robot is in dry cleaning mode, the opening and closing plate 631 closes the second air inlet 622; when the cleaning robot is in fabric cleaning mode, the opening and closing plate 631 opens the dust inlet.

[0058] In some embodiments, the opening and closing structure 63 further includes a driving member, which is connected to the opening and closing plate 631 in a transmission manner. The driving member is used to drive the opening and closing plate 631 to move relative to the air collector 62 to open and close the second air inlet 622. The driving member can be a device such as a motor, electric motor or electric cylinder. The opening and closing of the second air inlet 622 is realized by driving the opening and closing plate 631 to move through the driving member.

[0059] In other embodiments, the opening and closing plate 631 is configured to open the second air inlet 622 under the suction action of the suction source 61. It should be noted that the opening and closing plate 631 can be rotatably connected to the air collector 62. When the cleaning robot is in dry cleaning mode, the opening and closing plate 631 closes the second air inlet 622; when the cleaning robot needs to use the wet cleaning function, the opening and closing plate 631 opens the second air inlet 622 under the action of the airflow generated by the suction source 61. Understandably, the suction force of the suction source 61 can be adjusted to regulate the suction force of the airflow generated by the suction source 61 on the opening and closing plate 631. When the cleaning robot is in dry cleaning mode, the suction force of the suction source 61 is relatively small, and the suction force on the opening and closing plate 631 is less than the preset suction force threshold. At this time, the opening and closing plate 631 remains stationary, keeping the second air inlet 622 closed. When the cleaning robot needs to use the wet cleaning function, the suction force of the suction source 61 is relatively large, and the suction force of the opening and closing plate 631 is greater than the preset suction force threshold. The opening and closing plate 631 rotates under the action of suction to automatically open the second air inlet 622. There is no need to set up an additional driving component to drive the opening and closing plate 631 to rotate, which can reduce the production cost of the cleaning robot. The specific value of the preset suction threshold can be selected according to actual needs. For example, the preset suction threshold can be 8 kPa. When the cleaning robot is in dry cleaning mode, the suction power generated by the suction source 61 is 4 kPa. When the cleaning robot is in wet cleaning mode, the suction power generated by the suction source 61 is 10 kPa.

[0060] In some embodiments of this application, the opening and closing plate 631 has a first connecting end and a first movable end disposed opposite to the first connecting end. The first connecting end is rotatably connected to the air collector 62. The suction assembly 60 also includes an elastic member 632, which is connected to the first connecting end and the air collector 62. The elastic member 632 is used to apply a force to the opening and closing plate 631 to close the second air inlet 622.

[0061] In the dry cleaning mode, the first movable end keeps the second air inlet 622 closed under the elastic force of the elastic element 632. When the cleaning robot is in wet cleaning mode, the first movable end rotates away from the second air inlet 622 under the airflow generated by the suction source 61, thus opening the second air inlet 622. It can be understood that the elastic element 632 can be a torsion spring, providing rotational resistance to the opening and closing plate 631. When the first movable end of the opening and closing plate 631 rotates away from the second air inlet 622, it needs to overcome the resistance of the elastic element 632. By designing the elastic force of the elastic element 632, the magnitude of the resistance provided by the elastic element 632 to the opening and closing plate 631 can be designed, and a preset suction threshold can be designed.

[0062] In one embodiment, the first connecting end can be rotatably connected to the air collector 62 via a rotating shaft, the elastic member 632 can be sleeved on the rotating shaft, and the swing arm of the elastic member 632 abuts against the inner wall of the air collector 62.

[0063] In other embodiments, the suction source 61 can also be used to selectively connect to the dust collection chamber 41. When the cleaning robot only needs to use the wet cleaning function, the suction source 61 can be disconnected from the dust collection chamber 41; when the cleaning robot needs to use the dry cleaning function, the suction source 61 can be connected to the dust collection chamber 41. In this embodiment, the opening and closing structure 63 can be set at the first air inlet 621. Alternatively, in yet another embodiment, the suction source 61 can also selectively connect to both the dust collection chamber 41 and the wastewater chamber 51. In this embodiment, the cleaning robot can have an opening and closing structure set at the first air inlet 621 and the second air inlet 622 respectively. The working principle and structure of the opening and closing structure will not be described again here.

[0064] In some embodiments of this application, a partition structure 625 is further provided within the ventilation channel 624, dividing the ventilation channel 624 into a first air inlet channel 626 and a second air inlet channel 627. A first air inlet 621 communicates with the first air inlet channel 626, and a second air inlet 622 communicates with the second air inlet channel 627. The partition structure 625 has a first ventilation opening 625a, which connects the first air inlet channel 626 and the second air inlet channel 627. A converging air outlet 623 communicates with the first ventilation opening 625a. Specifically, the converging air outlet 623 can be disposed within the partition structure 625, and one of the first air inlet channel 626 and the second air inlet channel 627 is connected to the suction port 611 of the suction source 61 through the converging air outlet 623. Understandably, compared to the entire ventilation channel 624, the first air intake channel 626 and the second air intake channel 627 are narrower, which makes the airflow velocity in the first air intake channel 626 and the second air intake channel 627 faster, thereby enhancing the suction power of the dust suction port 11 and the dirt suction port 322.

[0065] In some embodiments, the dust collection box 40 has a dust collection outlet 42 communicating with the dust collection chamber 41 on the side near the air collector 62 (e.g., ...). Figure 4 The first air inlet 621 is located on the side of the air collector 62 near the dust collection box 40, and the first air inlet 621 is attached to the dust collection box 40 and connected to the dust collection outlet 42, thereby realizing the connection between the first air inlet 621 and the dust collection chamber 41, and at the same time making the arrangement of the suction component 60 and the dust collection box 40 more compact.

[0066] In some embodiments, the suction assembly 60 further includes a first connector 64, which has a first air guide channel 641, a first pair of interfaces 642, and a second pair of interfaces 643. The first air guide channel 641 connects the first pair of interfaces 642 and the second pair of interfaces 643. The first pair of interfaces 642 is attached to the air collector 62 and communicates with the second air inlet 622. The water tank assembly 50 is provided with a first opening 52 communicating with the sewage chamber 51 (e.g., ...). Figure 13 The second pair of interfaces 643 are attached to the water tank assembly 50 and connected to the first opening 52, making the arrangement of the suction assembly 60 and the water tank assembly 50 more compact, and at the same time making the connection of the air guide connection between the suction assembly 60 and the water tank assembly 50 more tight.

[0067] A first sealing element 71, which can be a sealing gasket, can be provided between the first pair of interfaces 642 and the air collector 62 to improve the sealing performance at the connection point. A second sealing element 72, which can also be a sealing gasket, can be provided between the second pair of interfaces 643 and the water tank assembly 50 to improve the sealing performance at the connection point. A third sealing element 73, which can be a sealing gasket, can be provided on the side of the opening and closing plate 631 near the second air inlet 622. The third sealing element 73 can improve the sealing performance between the opening and closing plate 631 and the air collector 62 when the opening and closing plate 631 closes the second air inlet 622.

[0068] In some embodiments, the suction assembly 60 further includes a second connector 65, which is connected to the air collector 62 and together with the air collector 62 forms a receiving cavity 66. The suction source 61 is housed in the receiving cavity 66, and the second connector 65 has an air outlet 651. The exhaust port 612 of the suction source 61 communicates with the air outlet 651. It is understood that the second connector 65 can be connected to the air collector 62 by means of adhesive bonding or screw connection. The second connector 65 can be used to hide the suction source 61 in the receiving cavity 66, thereby providing protection for the suction source 61 and making the airflow generated by the suction source 61 more concentrated, thus providing greater suction for the dust suction port 11 and the dirt suction port 322. Furthermore, the second connector 65 can guide the airflow discharged from the suction source 61, so that the airflow discharged from the suction source 61 is discharged out of the cleaning robot in a preset direction.

[0069] A fourth sealing element 74, which can be a sealing gasket, can be provided between the air intake 611 and the air collection port 623 of the suction source 61. The fourth sealing element 74 can improve the sealing performance between the air intake 611 and the air collection port 623 and also play a noise reduction role, reducing the wind noise generated when the suction source 61 starts up. A fifth sealing element 75, which can also be a sealing gasket, can be provided between the exhaust port 612 and the second connecting member 65 of the suction source 61. The fifth sealing element 75 can also be a sealing gasket. The fifth sealing element 75 can improve the sealing performance between the exhaust port 612 and the second connecting member 65 and also play a noise reduction role, reducing the wind noise generated when the suction source 61 starts up.

[0071] like Figures 13 to 16 As shown, in some embodiments of this application, the water tank assembly 50 includes a wastewater tank 53 and a clean water tank 54. The wastewater tank 53 has a wastewater chamber 51, and the clean water tank 54 has a clean water chamber. It is understood that by providing two independent water tanks (wastewater tank 53 and clean water tank 54), with each having its own independent wastewater chamber 51 and clean water chamber, mixing of the liquid in the clean water chamber with the liquid in the wastewater chamber 51 can be prevented during the cleaning robot's operation. Furthermore, the replenishment of water to the clean water chamber and the removal of dirt from the wastewater chamber 51 can be performed separately. In other embodiments, the wastewater chamber 51 and the clean water chamber can also be housed in the same enclosure, separated by a partition; that is, the wastewater tank 53 and the clean water tank 54 can be designed as a single enclosure.

[0072] The wastewater tank 53 is detachably connected to the machine body 10 to make cleaning the wastewater tank 53 more convenient. Specifically, the wastewater tank 53 can be connected to the machine body 10 by snap-fit, magnetic connection, etc.

[0073] In one embodiment, the water tank 54 can be detachably connected to the body 10, allowing the user to add water or cleaning agent to the water tank 54. Specifically, the water tank 54 can be connected to the body 10 via a snap-fit, magnetic connection, or other means.

The buckle 532d is slidably connected to the connecting frame 532c and can slide along the depth direction of the installation groove. The body 10 is provided with a slot that cooperates with the buckle 532d. The buckle 532d is engaged in the slot to realize the detachable connection between the buckle 532d and the body 10. Furthermore, connecting components 532 can be provided at both opposite ends of the sewage tank 53.

[0075] In one embodiment, the wastewater tank 53 is provided with a receiving groove 533, and at least a portion of the structure of the clean water tank 54 is located within the receiving groove 533 to reduce the overall volume of the cleaning robot.

[0076] In some embodiments of this application, a first opening 52 is provided in a sewage tank 53. A drain outlet 55 is provided on one side of the tank body 531 where a receiving groove 533 is provided. The drain outlet 55 is connected to the receiving groove 533 and the sewage chamber 51. Dirt in the sewage tank 53 can be discharged through the drain outlet 55. The drain outlet 55 is equipped with a sealing cover 56 to control its opening and closing. The sealing cover 56 is detachably connected to the tank body 531. The sealing cover 56 can close the drain outlet 55 to prevent dirt from being discharged from the drain outlet 55 during the operation of the cleaning robot. In addition, when the clean water tank 54 is installed in the receiving groove 533, it can cover and squeeze the sealing cover 56, thereby preventing the sealing cover 56 from falling off the tank body 531 due to vibration or other factors during the operation of the cleaning robot.

[0077] In one embodiment, the sewage tank 53 also has a second opening 57, which is connected to the sewage chamber 51 and to the suction port 322, so as to realize the connection between the suction port 322 and the sewage chamber 51.

[0078] In one embodiment, the cleaning robot also includes a water pump 80 (e.g., Figure 5 The water pump 80 is connected to the clean water tank and the spray nozzle 321. The water pump 80 is used to draw the cleaning liquid from the clean water tank to the spray nozzle 321 and spray it out through the spray nozzle 321. In other embodiments, the cleaning robot may also use an air pump to apply positive pressure to the clean water tank to discharge the cleaning liquid from the clean water tank.

[0079] like Figures 17 to 19As shown, in some embodiments of this application, the fabric wet cleaning component 30 further includes a mounting bracket 32, which is located at the bottom of the body 10 and connected to the body 10.

The spray chamber 326 and the suction chamber 327 are both isolated from the receiving tank 323. It is understandable that by setting independent suction chambers 327 and spray chambers 326 on the mounting bracket 32, the dirt sucked by the suction port 322 can be sucked into the sewage chamber 51 through the suction chamber 327, and the cleaning liquid in the clean water chamber can flow to the spray hole 321 through the spray chamber 326 and be sprayed out through the spray hole 321, so that the cleaning liquid and dirt do not interfere with each other, preventing dirt from remaining in the spray chamber 326 and causing secondary pollution, and also preventing dirt from clogging the spray hole 321.

[0081] Furthermore, the spray chamber 326 and the suction chamber 327 are located on opposite sides of the receiving tank 323, the spray hole 321 is opposite to the spray chamber 326, and the suction port 322 is opposite to the suction chamber 327, so that the spray hole 321 and the suction port 322 maintain a sufficient distance to prevent the spray hole 321 and the suction port 322 from interfering with each other.

[0082] In one embodiment, multiple spray holes 321 may be provided, and the multiple spray holes 321 are arranged at intervals along the axial direction of the fabric cleaning member 31 to improve spray efficiency and spray effect.

The cover plate 329 is detachably connected to the frame body 328 and is used to open and close the cleaning port 328a. When the spray hole 321 becomes blocked, the cover plate 329 can be removed, and the spray chamber 326 and the spray hole 321 can be cleaned through the cleaning port 328a. The detachable connection between the cover plate 329 and the frame body 328 includes, but is not limited to, snap-fit, threaded connection, or latching connection. In other embodiments, at least one of the spray hole 321 and the suction port 322 can also be directly provided on the machine body 10.
