[0032] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] The present application provides a cleaning robot. Specifically, as Figure 1 and Figure 2As shown, the cleaning robot includes a body 10 and drive wheels 12. The drive wheels 12 are arranged 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. The body 10 is used to provide an installation space and support for components such as the drive wheels 12. The overall shape of the body 10 can be disc-shaped, square-plate-shaped or other shapes. The material of the outer shell of the body 10 can be plastic, metal or other materials. The drive wheels 12 of the cleaning robot are the walking wheels of the cleaning robot. When the cleaning robot walks, the drive wheels 12 provide driving force, enabling the cleaning robot to walk automatically without the need for manual thrust from the user.

[0034] More specifically, as Figure 2 and Figure 3 shown, the cleaning robot further includes a fabric wet cleaning assembly 30, a water tank assembly 50 and a suction assembly 60.

[0035] Among them, the fabric wet cleaning assembly 30 is connected to the body 10. The fabric wet cleaning assembly 30 is used for wet cleaning of fabric products. The fabric wet cleaning assembly 30 has a liquid spraying hole 321 and a dirt suction port 322. The water tank assembly 50 has a separated clean water chamber and a sewage chamber 51 (as Figure 15 ), the clean water chamber is communicated with the liquid spraying hole 321, and the sewage chamber 51 is communicated with the dirt suction port 322. The clean water chamber is used to store cleaning liquids such as clean water or a mixture of clean water and a cleaning agent. The sewage chamber 51 can be used to temporarily store liquid garbage such as urine and sewage, or dry-wet mixed garbage. 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 garbage is sucked from the dirt suction port 322 into the sewage chamber 51. The suction source 61 can be a device such as a blower or a pump that can provide suction for the dirt suction port 322.

[0036] It is worth mentioning that the fabric products in this application mostly refer to soft decorations laid on the ground, such as carpets and floor mats. For such fabric products, the cleaning robot can automatically walk to the surface of the fabric products. In other embodiments, the fabric products can also include items such as fabric sofas and mattresses that are at a certain height from the ground. For such fabric products, the cleaning robot can climb to the surface of the fabric products by means of a climbing structure or be carried to the surface of the fabric products by the user.

[0037] The cleaning robot of the present application can perform wet cleaning on fabric products. When the cleaning robot is located on the surface of the fabric product, the cleaning liquid in the clean water chamber is sprayed onto the fabric product through the liquid spraying holes 321, so that the cleaning liquid is mixed with the dirt on the fabric product. The suction component 60 can be used to provide suction for the dirt suction port 322, so as to suck the dirt into the sewage chamber 51 through the dirt suction port 322. As the cleaning robot moves automatically on the surface of the fabric product, the cleaning robot can perform a comprehensive wet cleaning on the fabric product to ensure the cleaning effect of the fabric product, and the whole process does not require user participation, saving time and effort.

[0038] In one embodiment, the fabric wet cleaning component 30 is detachably connected to the body 10. The cleaning robot further includes a mopping component detachably connected to the body 10. The body 10 has a first installation area for installing the fabric wet cleaning component 30 or the mopping component. It can be understood that, as the name implies, the mopping component is a component for mopping and cleaning the ground, mainly used for cleaning hard floors, such as floors paved with wooden floors, tiles or marble. In this embodiment, the fabric wet cleaning component 30 and the mopping component are two interchangeable components, but the installation areas of the fabric wet cleaning component 30 and the mopping component are the same. When the fabric wet cleaning component 30 is needed, the fabric wet cleaning component 30 is installed in the first installation area, and at this time the mopping component is in a disassembled state; when it is necessary to replace it with the mopping component, the fabric wet cleaning component 30 is disassembled from the body 10, and then the mopping component can be installed in the first installation area.

[0039] In another embodiment, the cleaning robot can be installed with both the mopping component and the fabric wet cleaning component 30. Specifically, the body 10 has a first installation area and a second installation area. The first installation area is used for installing the fabric wet cleaning component 30, and the second installation area is used for installing the mopping component. The first installation area can be located in front of or behind the second installation area. It can be understood that, in this embodiment, the fabric wet cleaning component 30 and the mopping component are two non-interfering components, and the installation areas of the fabric wet cleaning component 30 and the mopping component are different. When the fabric wet cleaning component 30 is needed, the fabric wet cleaning component 30 is installed in the first installation area. At this time, the mopping component can be in a disassembled state or an installed state. When the mopping component is in the installed state, the mopping component can be controlled to be in a non-working state; when the mopping component is needed, the mopping component is installed in the second installation area. At this time, the fabric wet cleaning component 30 can be in a disassembled state or an installed state. When the fabric wet cleaning component 30 is in the installed state, the fabric wet cleaning component 30 can be controlled to be in a non-working state. Of course, in some embodiments, the mopping component can also be omitted, which can be determined according to the application scenario of the cleaning robot.

[0040] In an embodiment of the present application, the mopping assembly includes a roller rotatably connected to the 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 is communicated with the clean water chamber. The roller is used to receive the clean water output from the liquid outlet. The liquid inlet is communicated with the sewage chamber. The suction source is further used to suck the garbage from the liquid inlet into the sewage chamber. It can be understood that the roller can rotate relative to the body to clean the ground. The liquid outlet can be communicated with the clean water chamber. During the mopping process, the liquid outlet can output clean water to the roller, and the liquid inlet sucks the garbage into the sewage chamber. In this embodiment, the mopping assembly and the fabric 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 the overall volume of the cleaning robot. In other embodiments, the mopping assembly can also be configured with a separate water tank assembly and a suction source.

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

[0042] In some embodiments of the present application, the cleaning robot may further include a dry cleaning assembly 20. The dry cleaning assembly 20 is disposed at the bottom of the body 10 and connected to the body. As the name implies, the dry cleaning assembly 20 is a component for dry cleaning the surface to be cleaned. The surface to be cleaned mentioned here can be the hard ground mentioned above or the fabric product mentioned above. It can be 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, the dry cleaning assembly 20 can be used for cleaning; when the cleaning robot is in the fabric cleaning state, the fabric wet cleaning assembly 30 or the fabric wet cleaning assembly 30 and the dry cleaning assembly 20 can be used for cleaning, so that the cleaning robot can be applied to more cleaning scenarios.

[0043] Among them, the dry cleaning assembly 20 can be arranged on the front side of the fabric wet cleaning assembly 30. It should be noted that in the traveling direction XX of the cleaning robot, the cleaning robot usually has a head (or the front part) and a tail (or the rear part). The forward direction of the cleaning robot is from the tail to the head, and the backward direction of the cleaning robot is from the head to the tail. The dry cleaning assembly 20 is arranged on the front side of the fabric wet cleaning assembly 30, that is, the direction from the fabric wet cleaning assembly 30 to the dry cleaning assembly 20 is parallel to the forward direction of the cleaning robot. When the cleaning robot travels in the forward direction to clean the fabric product, the dry cleaning assembly 20 can first perform dry cleaning on the fabric product to remove some of the garbage on the fabric product, and then the fabric wet cleaning assembly 30 can perform wet cleaning on the fabric product, which can further improve the cleaning effect of the carpet. Of course, in other embodiments, the dry cleaning assembly 20 can also be omitted, which can be determined according to the actual functional requirements of the cleaning robot.

[0044] In one embodiment, the fabric wet cleaning assembly 30 includes a fabric cleaning member 31. The fabric cleaning member 31 is a first roller brush or a first flat brush. The first roller brush is used for rotatably connecting to the body, and the first flat brush is used for being relatively fixed to the body. It can be understood that when using the first roller brush, the first roller brush is disposed at the bottom of the body and can rotate relative to the body. The first roller brush can be a roller brush with bristles or a rubber roller brush without bristles; when using the first flat brush, the first flat brush is fixed to the bottom of the body, and the first flat brush can have bristles or rubber brush strips. In this embodiment, it should be explained that the fabric wet cleaning assembly 30 can include both the first roller brush and the first flat brush, and the first roller brush and the first flat brush are selectively connected to the body according to the category of the fabric product. In other embodiments, the fabric wet cleaning assembly 30 can be only one of the first roller brush and the first flat brush, and no specific limitation is made here.

[0045] In one embodiment, the dry cleaning assembly 20 includes a dry cleaning member 21 rotatably connected to the body. The fabric cleaning member 31 includes first bristles 311, and the dry cleaning member 21 includes second bristles. The hardness of the first bristles 311 is greater than that of the second bristles. It can be understood that both the dry cleaning assembly 20 and the fabric cleaning member 31 have bristles. The first bristles 311 of the fabric cleaning member 31 are made of a harder material, so that the fabric cleaning member 31 has good friction and poor water absorption. When the cleaning robot walks on the surface of the fabric product, the fabric cleaning member 31 can vigorously rub the surface of the fabric product, so that the dirt is separated from the fabric product, and then the dirt is more easily sucked into the sewage chamber 51. Especially for carpets with a certain thickness of fluff, the first bristles 311 of the fabric cleaning member 31 can penetrate into the fluff and clean the dirt deep in the carpet. At the same time, for the relatively hard first bristles 311, liquid and dirt are not easily attached, which can prevent the fabric cleaning member 31 from causing secondary pollution to the carpet when cleaning the carpet, and can also reduce the frequency of the user cleaning the fabric cleaning member 31. The second bristles of the dry cleaning member 21 are made of a softer material, which can prevent the dry cleaning member 21 from scratching the hard floor when cleaning the hard floor.

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

[0047] Furthermore, the length of the fabric cleaning member 31 is greater than the length of the dry cleaning member 21, so that the fabric cleaning member 31 has a larger cleaning area, which can improve the cleaning efficiency of the carpet. The length of the fabric cleaning member 31 mentioned here refers to the length of the fabric cleaning member 31 in the left-right direction of the cleaning robot, and the length of the dry cleaning member 21 is the same. Further, the drive wheel 12 is located between the dry cleaning member 21 and the fabric cleaning member 31, which can increase the distance between the dry cleaning member 21 and the fabric cleaning member 31, prevent the dry cleaning member 21 and the fabric cleaning member 31 from interfering with each other, and can also make the center of gravity of the cleaning robot close to the middle part of the cleaning robot, preventing the cleaning robot from tipping forward or tipping backward.

[0048] In one embodiment, the fabric cleaning member 31 is located between the liquid spraying hole 321 and the sewage suction port 322, and the liquid spraying hole 321 is located on the front side of the fabric cleaning member 31. When the cleaning robot moves forward to clean the fabric product, it can first spray water through the liquid spraying hole 321, then clean the fabric product through the fabric cleaning member 31, and then suck the garbage into the sewage chamber 51 through the sewage suction port 322. It is not difficult to understand that for a cleaning robot that omits the fabric cleaning member 31, the liquid spraying hole 321 is located on the front side of the sewage suction port 322.

[0049] In some embodiments of the present application, the body has a dust collection chamber 41 (such as Figure 12 ), and a dust suction port 11 communicating with the dust collection chamber 41; wherein, the suction source 61 is also used to communicate with the dust collection chamber 41 to suck garbage from the dust suction port 11 into the dust collection chamber 41. It can be understood that in this embodiment, the suction source 61 can be a fan. When the cleaning robot is in the dry cleaning state, the suction source 61 can also be used to provide suction for the dust suction port 11, and suck the dry garbage on the ground into the dust collection chamber 41 through the dust suction port 11. The suction requirement of the dust suction port 11 and the sewage suction port 322 can be met by one suction source 61, so as to realize the sewage suction requirement of the cleaning robot in the dry cleaning state and the fabric cleaning state, reduce the number of suction sources 61 in the cleaning robot, and thus reduce the production cost and overall volume of the cleaning robot. Of course, in other embodiments, a fan for dry cleaning can be separately configured.

[0050] In one embodiment, the cleaning robot may further include a dust collection box 40, which is detachably installed 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, a dust collection chamber 41 can also be directly formed in the body 10 by setting a partition plate or other structures in the body 10.

[0051] As Figure 3 shown, the body 10 may include a body 13, a frame cover 14 and a face cover 15. The dry cleaning assembly 20 and the fabric wet cleaning assembly 30 are installed at the bottom of the body 13. The frame cover 14 covers the body 13. The dust collection box 40, the suction assembly 60 and the water tank assembly 50 are all installed in the space formed by the connection of the body 13 and the frame cover 14. The face cover 15 is stacked on the frame cover 14 to play a role of decoration and protection.

[0052] As Figures 3 to 5 shown, in some embodiments of the present application, the dust collection chamber 41 and the water tank assembly 50 are arranged along the traveling direction XX of the cleaning robot. The suction assembly 60 is located between the dust collection box 40 and the water tank assembly 50, so that the arrangement of the dust collection box 40, the water tank assembly 50 and the suction assembly 60 is more compact, the overall volume of the cleaning robot can be reduced, and the connection between the suction assembly 60 and the dust collection box 40 and the water tank assembly 50 is more convenient.

[0053] In this embodiment, the suction source 61 is used to selectively communicate with the sewage chamber 51. It can be understood that when the cleaning robot is in the dry cleaning state, the suction source 61 communicates with the dust collection chamber 41. At this time, the suction source 61 can be disconnected from the sewage chamber 51 to increase the suction force at the dust suction port 11; when the cleaning robot needs to use the wet cleaning function, such as mopping a hard floor or wet cleaning a fabric product, the suction source 61 can be communicated with the sewage chamber 51, so that one suction source 61 can meet the suction requirements for both dry cleaning and wet cleaning.

[0054] As Figures 6 to 11 shown, in some embodiments of the present application, the suction assembly 60 further includes a wind collecting member 62. The wind collecting member 62 has a ventilation passage 624 and a first air inlet 621, a second air inlet 622 and an air collecting outlet 623 that communicate with the ventilation passage 624. The first air inlet 621 and the second air inlet 622 both communicate with the air collecting outlet 623. The first air inlet 621 communicates with the dust collection chamber 41, the second air inlet 622 is selectively communicated with the sewage chamber 51, and the air collecting outlet 623 communicates with the suction source 61.

[0055] Among them, at least when the cleaning robot is in the fabric cleaning state, the second air inlet 622 communicates with the sewage chamber 51, so that the suction source 61 can provide suction force for the sewage suction port 322 through the sewage chamber 51 at this time. It can be understood that the wind collecting member 62 is used to connect the suction source 61 with the dust collection box 40 and the water tank assembly 50. By using the wind collecting member 62, one suction source 61 can meet the suction requirements of the dust suction port 11 and the sewage suction port 322. When the cleaning robot is in the dry cleaning state, the first air inlet 621 communicates with the dust collection chamber 41. The airflow generated by the suction source 61 sequentially passes through the dust suction port 11, the dust collection chamber 41, the first air inlet 621, the ventilation passage 624, the air collecting outlet 623 and the air suction port 611 of the suction source 61, so as to generate negative pressure at the dust suction port 11, so that the garbage is sucked into the dust collection chamber 41 through the dust suction port 11; when the cleaning robot is in the fabric cleaning state, the second air inlet 622 communicates with the sewage chamber 51, and the suction source 61 generates two airflows. One airflow flows from the dust suction port 11 to the suction source 61, and the other airflow sequentially passes through the sewage suction port 322, the sewage chamber 51, the second air inlet 622, the ventilation passage 624, the air collecting outlet 623 and the air suction port 611, so as to generate negative pressure at the sewage suction port 322, so that the garbage is sucked into the sewage chamber 51 through the sewage suction port 322.

[0056] Continue to refer to Figures 6 to 11As shown, in some embodiments of the present application, the suction assembly 60 further includes an opening and closing structure 63, which includes an opening and closing plate 631, which is movably connected to the wind collecting member 62, and 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, so as to achieve the connection and disconnection of 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 to connect the ventilation channel 624 with the sewage chamber 51; when the wet cleaning function is not required, the opening and closing plate 631 closes the second air inlet 622, so as to separate the ventilation channel 624 from the sewage chamber 51.

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

[0058] In some embodiments, the opening and closing structure 63 also includes a driving member, which is transmission-connected to the opening and closing plate 631, and is used to drive the opening and closing plate 631 to move relative to the wind collecting member 62 to open and close the second air inlet 622; wherein the driving member can be a device such as a motor, a motor or an electric cylinder, and the opening and closing plate 631 is driven by the driving member to move, thereby realizing the opening and closing of the second air inlet 622.

[0059] In some 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 collecting member 62. When the cleaning robot is in the dry cleaning state, 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. It can be understood that the suction force of the suction source 61 can be adjusted to adjust 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 the dry cleaning state, the suction force of the suction source 61 is small, and the suction force on the opening and closing plate 631 is less than the preset suction threshold value. At this time, the opening and closing plate 631 remains stationary, so that the second air inlet 622 remains closed. When the cleaning robot needs to use the wet cleaning function, the suction force of the suction source 61 is large, and the suction force on the opening and closing plate 631 is greater than the preset suction threshold value. The opening and closing plate 631 rotates under the suction force to automatically open the second air inlet 622, and there is no need to set an additional driving member to drive the opening and closing plate 631 to rotate, which can reduce the production cost of the cleaning robot. Among them, the specific value of the preset suction threshold value can be selected according to actual needs. For example, the preset suction threshold value can be 8 kPa. When the cleaning robot is in the dry cleaning state, the suction force generated by the suction source 61 is 4 kPa. When the cleaning robot is in the wet cleaning state, the suction force generated by the suction source 61 is 10 kPa.

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

[0061] Among them, when the cleaning robot is in the dry cleaning state, the first movable end keeps the second air inlet 622 closed under the elastic force of the elastic member 632; when the cleaning robot is in the wet cleaning state, the first movable end rotates away from the second air inlet 622 under the action of the airflow generated by the suction source 61 to open the second air inlet 622. It can be understood that the elastic member 632 can be a torsion spring. The elastic member 632 is used to provide a rotational resistance for 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 member 632. By designing the elastic force of the elastic member 632, the magnitude of the resistance provided by the elastic member 632 for the opening and closing plate 631 can be designed, and the preset suction threshold value can be designed.

[0062] In one embodiment, the first connection end can be rotatably connected to the air collecting member 62 through 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 collecting member 62.

[0063] In other embodiments, the suction source 61 can also be used to selectively communicate with the dust collecting cavity 41. When the cleaning robot only needs to use the wet cleaning function, the suction source 61 can be disconnected from the dust collecting cavity 41; when the cleaning robot needs to use the dry cleaning function, the suction source 61 is communicated with the dust collecting cavity 41. In this embodiment, the opening and closing structure 63 can be arranged at the first air inlet 621. Or, in yet another embodiment, the suction source 61 can also be selectively communicated with both the dust collecting cavity 41 and the sewage cavity 51. In this embodiment, the cleaning robot can be provided with an opening and closing structure 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 in detail here.

[0064] In some embodiments of the present application, a partition structure 625 is further arranged in the ventilation channel 624.

The first air inlet 621 is communicated with the first air inlet channel 626, the second air inlet 622 is communicated with the second air inlet channel 627. The partition structure 625 has a first ventilation opening 625a, and the first ventilation opening 625a communicates the first air inlet channel 626 with the second air inlet channel 627. The air collecting opening 623 is communicated with the first ventilation opening 625a. Specifically, the air collecting opening 623 can be arranged on the partition structure 625, and one of the first air inlet channel 626 and the second air inlet channel 627 is communicated with the suction port 611 of the suction source 61 through the air collecting opening 623. It can be understood that, compared with the entire ventilation channel 624, the first air inlet channel 626 and the second air inlet channel 627 are narrower, so that the air flow velocity in the first air inlet channel 626 and the second air inlet channel 627 is faster, thereby enhancing the suction force of the dust suction port 11 and the sewage suction port 322.

[0065] In some embodiments, one side of the dust collecting box 40 close to the air collecting member 62 has a dust collecting air outlet 42 (such as Figure 4 ) communicating with the dust collecting cavity 41. The first air inlet 621 is arranged on the side of the air collecting member 62 close to the dust collecting box 40, and the first air inlet 621 is attached to the dust collecting box 40 and communicated with the dust collecting air outlet 42, so as to realize the communication between the first air inlet 621 and the dust collecting cavity 41, and at the same time make the arrangement of the suction assembly 60 and the dust collecting box 40 more compact.

[0066] In some embodiments, the suction assembly 60 further includes a first connecting member 64. The first connecting member 64 has a first air guiding channel 641, a first pair of interfaces 642, and a second pair of interfaces 643.

A first opening 52 communicating with the sewage chamber 51 is provided on the water tank assembly 50 (such as Figure 13 ). The second pair of interfaces 643 is attached to the water tank assembly 50 and communicates with 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 at the air guiding connection between the suction assembly 60 and the water tank assembly 50 tighter.

[0067] Wherein, a first sealing member 71 may be provided between the first pair of interfaces 642 and the air collecting member 62.

A second sealing member 72 may be provided between the second pair of interfaces 643 and the water tank assembly 50. The second sealing member 72 may be a sealing rubber pad, which can improve the sealing performance at the docking portion between the second pair of interfaces 643 and the water tank assembly 50. A third sealing member 73 may be provided on the side of the opening and closing plate 631 close to the second air inlet 622. The third sealing member 73 may be a sealing rubber pad, and the third sealing member 73 can improve the sealing performance between the opening and closing plate 631 and the air collecting member 62 when the opening and closing plate 631 closes the second air inlet 622.

The air outlet 612 of the suction source 61 communicates with the air outlet 651. It can be understood that the second connecting member 65 can be connected to the air collecting member 62 by means of gluing or screw connection. The second connecting member 65 can hide the suction source 61 in the receiving cavity 66 to provide protection for the suction source 61, and make the airflow generated by the suction source 61 more concentrated, so that a greater suction force can be provided for the dust suction port 11 and the sewage suction port 322. And the second connecting member 65 can guide the airflow discharged by the suction source 61, so that the airflow discharged by the suction source 61 is discharged outside the cleaning robot in a preset direction.

[0069] Among them, a fourth seal 74 can be provided between the suction port 611 of the suction source 61 and the air collecting port 623.

It can be understood that by providing two independent water tanks (the sewage tank 53 and the clean water tank 54), and the sewage tank 53 and the clean water tank 54 respectively have independent sewage cavities 51 and clean water cavities, it is possible to prevent the liquid in the clean water cavity from mixing with the liquid in the sewage cavity 51 during the operation of the cleaning robot, and the work of replenishing water to the clean water cavity and discharging the dirt in the sewage cavity 51 can be carried out separately. In other embodiments, the sewage cavity 51 and the clean water cavity can also be arranged in the same box body and separated by a partition board, that is, the sewage tank 53 and the clean water tank 54 can be designed as one box body.
