[0038] In the related art, during the working process of the cleaning robot, some components of the cleaning robot generate heat, such as a control assembly and a driving assembly. The control assembly can control the working of the cleaning robot, and the driving assembly can drive the movement of the moving components of the cleaning robot. However, if the cleaning robot cannot dissipate the heat of the heat-generating components in time, the heat will continue to accumulate, causing the heat-generating components to overheat and be damaged, thereby affecting the normal working of the cleaning robot. In order to solve this problem, the present disclosure provides a cleaning robot 100 (shown in FIG. 1) and a cleaning system 1000 (shown in FIG. 2). Figure 1 Figure 8

[0039] Please refer to Figure 1 and Figure 2 , and combine Figure 3 and Figure 4 ​​The present disclosure provides a cleaning robot 100. The cleaning robot 100 comprises a body 10, a first air duct 106, a heat dissipation hole 107, a suction member 60, a control module 70 and a cleaning module 30. The body 10 comprises opposite front and rear sides 101 and 102 along a forward direction X of the cleaning robot 100, and comprises left and right sides 103 and 104 along a width direction Y of the body 10. The first air duct 106 is arranged on the left side 103 of the body 10. The heat dissipation hole 107 is arranged on the body 10 and located at the rear side of the first air duct 106, and the heat dissipation hole 107 is in communication with the first air duct 106. The suction member 60 is arranged between the left side 101 of the body 10 and the rear side 102 of the body 10, and the suction member 60 is in communication with the first air duct 106. The control module 70 is arranged on the body 10 and located at the right side of the first air duct 106, and the control module 70 is used for controlling the working of the cleaning robot 100. The control module 70 comprises a control assembly 71 and a heat dissipation member 73, the heat dissipation member 73 is connected with the control assembly 71 and at least partially extends into the first air duct 106. The cleaning module 30 is arranged on the rear side 102 of the body 10, and the cleaning module 30 comprises a cleaning member 33 and a driving member 35. The driving member 35 is used for driving the cleaning member 33 to move relative to a surface to be cleaned so as to clean the surface to be cleaned, and the driving member 35 is located at the rear side of the heat dissipation hole 107. In the case that the suction member 60 works and generates a suction air flow in the first air duct 106, the suction air flow is used for dissipating heat of the heat dissipation member 73 to achieve heat dissipation of the control assembly 71, and the suction air flow flows to the driving member 35 through the heat dissipation hole 107 to dissipate heat of the driving member 35.

[0040] It can be understood that the cleaning robot 100 is an intelligent device capable of realizing functions such as sweeping, dust collecting and mopping. The cleaning robot 100 includes but is not limited to a sweeping robot, a mopping robot, a sweeping and mopping integrated robot, an intelligent robot and a mobile robot, etc. The mopping robot can be used for wiping and cleaning the surface to be cleaned. The sweeping and mopping integrated robot can be used for sweeping and wiping and cleaning the surface to be cleaned. It should be noted that in one example, the surface to be cleaned can be the ground in a building. In another example, the surface to be cleaned can also be the surface of an object to be cleaned such as a wall surface, a window surface or a bed surface, a floor, a marble surface, a carpet, etc.

[0041] The body 10 is a component for loading and protecting elements other than the body 10, including but not limited to the suction member 60, the control module 70 and the cleaning module 30, etc. The material of the body 10 can be a metal material and / or a non-metal material. The metal material includes but is not limited to aluminum, iron, steel or aluminum alloy, etc. The non-metal material includes but is not limited to plastic, etc.

[0042] The orientations described in the embodiments of the present disclosure are defined with the cleaning robot 100 being carried on a surface to be cleaned. The "front side 101", "rear side 102", "left side 103" and "right side 104" are all relative to the advancing direction X of the cleaning robot 100. When the cleaning robot 100 moves forward along the advancing direction X, the front end of the body 10 closest to the advancing direction X is the front side 101 of the body 10, or, with the center point of the body 10 as a dividing line, the area of the body 10 closest to the front end of the advancing direction X is the front side 101 of the body 10; the rear end of the body 10 closest to the advancing direction X is the rear side 102 of the body 10, or, with the center point of the body 10 as a dividing line, the area of the body 10 closest to the rear end of the advancing direction X is the rear side 102 of the body 10; when the cleaning robot 100 moves forward along the advancing direction X, the left end of the body 10 closest to the width direction of the cleaning robot 100 is the left side 103 of the body 10, or, with the center point of the body 10 as a dividing line, the area of the body 10 closest to the left end of the width direction is the left side 103 of the body 10; when the cleaning robot 100 moves forward along the advancing direction X, the right end of the body 10 closest to the width direction of the cleaning robot 100 is the right side 104 of the body 10, or, with the center point of the body 10 as a dividing line, the area of the body 10 closest to the right end of the width direction is the right side 103 of the body 10. That is, the "front side 101", "rear side 102", "left side 103" and "right side 104" can be a side wall or an end of the corresponding orientation of the body 10 of the cleaning robot 100, or a region of the corresponding orientation of the body 10 of the cleaning robot 100.

[0043] For example, for a cleaning robot 100 of a regular shape, the center point of the body 10 can be the center point of the regular shape, for example, the center of a circular body 10 is the center; for a cleaning robot 100 of an irregular shape, the center point of the body 10 can be where the center of gravity of the cleaning robot 100 is located. It should be noted that the shape of the cleaning robot 100 defined in the present disclosure is approximately close to a certain shape (e.g., approximately close to a circle), not an absolute standard geometric figure.

[0044] Similarly, with the advancing direction X of the cleaning robot 100 as the reference direction, the rear side of the first air duct 106 can be the area located behind the first air duct 106, or the rear end of the first air duct 106 closest to the advancing direction X of the cleaning robot 100; the right side of the first air duct 106 can be the area located to the right of the first air duct 106, or the right end of the first air duct 106 closest to the width direction of the cleaning robot 100 when facing the front side 101 of the body 10.

[0045] The suction member 60 is a component of the cleaning robot 100 for extracting dirt by generating suction force or negative pressure. In some embodiments of the present disclosure, the cleaning robot 100 further comprises a dirt receiving cavity 47 (e.g., a dust box) disposed in the body 10, which is used to collect the dirt swept by the roller brush module 41 (e.g., the roller brush module 41 is located below the body 10 to contact the surface to be cleaned, as indicated by the dashed line). Figure 2 The dirt can be liquid, solid (e.g., paper or dust), or a mixture of solid and liquid, which is not limited in the present disclosure. Specifically, the first air duct 106 is in communication with the dirt receiving cavity 47. When the roller brush module 41 sweeps the surface to be cleaned, the suction member 60 works and generates suction airflow in the first air duct 106, so that the roller brush module 41 can sweep the dirt on the surface to be cleaned into the dirt receiving cavity 47, which can collect and store the dirt swept by the roller brush module 41, thereby preventing the dirt from falling onto the cleaned surface to be cleaned and causing pollution to the surface to be cleaned, and further ensuring the cleaning effect of the cleaning robot 100. It should be noted that, in some embodiments, the suction member 60 can be a fan, including but not limited to a centrifugal fan, an axial fan, and a cross-flow fan. In some embodiments of the present disclosure, the fan can be an axial fan.

[0046] For example, a filter screen is provided between the first air duct 106 and the dirt receiving cavity 47, which can filter the dirt to prevent the dirt from entering the first air duct 106 and damaging the suction member 60, thereby improving the stability and reliability of the operation of the suction member 60.

[0047] In the embodiments of the present disclosure, the cleaning robot 100 can realize right-side edge cleaning, i.e., the right side 104 of the body 10 can clean the edge of a wall or furniture. It can be understood that when the cleaning robot 100 performs right-side edge cleaning, the center of gravity of the cleaning robot 100 can be offset to the right, which can affect the stability of the cleaning robot 100. Therefore, in some embodiments of the present disclosure, the suction member 60 is disposed between the left side 103 of the body 10 and the rear side 102 of the body 10. Thus, the center of gravity of the cleaning robot 100 can be approximately centered when the cleaning robot 100 performs right-side edge cleaning, so that the cleaning member 33 of the cleaning robot 100 can press the surface to be cleaned more uniformly, preventing the occurrence of adverse phenomena such as local overpressure or local leakage gaps, and improving the stability of the operation of the cleaning robot 100 and the cleaning effect.

[0048] In addition, in some embodiments of the present disclosure, the first air duct 106 is arranged on the left side 103 of the body 10, so that on the one hand, the suction member 60 can be connected to the first air duct 106, the flow formation of the suction air flow is shortened, the suction resistance is reduced, and thus the suction efficiency of the suction member 60 can be improved, and the cleaning effect of the cleaning robot 100 is ensured; on the other hand, the cleaning module 30 can be prevented from interfering with the first air duct 106 when the right side of the cleaning robot 100 is cleaned along the edge, and the normal operation of the cleaning robot 100 is ensured.

[0049] The control assembly 71 is a component capable of controlling the operation of the cleaning robot 100. For example, the control module 70 can control the movement of the cleaning robot 100 (including forward movement, backward movement, turning, etc.), plan and execute a cleaning path, monitor the operating state of the cleaning robot 100, and the like. For more details, please refer to the description of the cleaning robot 100. Figure 5 In some embodiments of the present disclosure, the control assembly 71 includes a main control board 711 and a chip 713 arranged on the main control board 711. The main control board 711 and the chip 713 cooperate with each other to enable the cleaning robot 100 to effectively realize functions such as autonomous navigation, obstacle avoidance, and planning of a cleaning path, so as to ensure that the cleaning robot 100 can normally and efficiently operate and complete various cleaning tasks. The chip 713 can include multiple chips. Among them, the multiple chips 713 can be sensor chips, storage chips, and drive control chips, etc., which are not limited herein.

[0050] The heat dissipation member 73 is an element capable of conducting, convecting or radiating heat from a heat source to the surrounding environment. The material of the heat dissipation member 73 includes but is not limited to copper, aluminum, heat-conducting silicone grease, and heat-conducting silica gel, etc. In some embodiments of the present disclosure, the heat dissipation member 73 is connected to the control assembly 71 and at least partially extends into the first air duct 106, so that the heat dissipation member 73 can conduct the heat of the control assembly 71 to the first air duct 106 by heat conduction, and the heat is taken away by the flow of the suction air flow, so as to realize heat dissipation of the control assembly 71, and ensure that the control assembly 71 will not be damaged due to overheating caused by heat accumulation. In the embodiments of the present disclosure, the heat dissipation method of the control assembly 71 is relatively simple, and the suction function of the suction member 60 can be fully utilized, which realizes efficient use of resources, so that the heat dissipation efficiency of the heat dissipation member 73 on the control assembly 71 is higher, thereby reducing the number of parts of the cleaning robot 100 while reducing the production cost, and simplifying the structural design of the cleaning robot 100.

[0051] It can be understood that, since the chip 713 is a highly integrated electronic component, a large number of transistors, resistors, capacitors and other circuit elements are contained in the chip 713, and a large amount of heat is generated during the operation of the chip 713, and the heat of the chip 713 is difficult to effectively dissipate, and is easy to cause overheating damage. Therefore, in the present disclosure, the heat dissipation member 73 can be connected with the chip 713, so that the heat dissipation member 73 can directly dissipate heat for the chip 713, thereby improving the heat dissipation efficiency and improving the heat dissipation effect of the heat dissipation member 73 on the control assembly 71.

[0052] The cleaning module 30 is a module in the cleaning robot 100 that participates in cleaning the to-be-cleaned surface by providing mopping force. The cleaning member 33 is a component in the cleaning module 30 that specifically provides mopping force to clean the to-be-cleaned surface. In some embodiments of the present disclosure, the cleaning member 33 is arranged on the body 10 and located at the bottom of the body 10 (the side of the body 10 facing the to-be-cleaned surface when the cleaning robot 100 is carried on the to-be-cleaned surface), so that in the case that the cleaning robot 100 is in a normal cleaning state, the cleaning member 33 can be tightly attached to the to-be-cleaned surface to achieve the mopping function.

[0053] In one embodiment, the cleaning member 33 is a track-type cleaning member, and in this case, the cleaning robot 100 is a track-type cleaning robot. In another embodiment, the cleaning member 33 is a roller-type cleaning member, and in this case, the cleaning robot 100 is a roller-type cleaning robot. In still some embodiments, the cleaning member 33 can be a flat mop-type cleaning member or a disc-type cleaning member, and in this case, the cleaning robot 100 is a flat mop-type cleaning robot or a disc-type cleaning robot. Regardless of the type of the cleaning member 33, in the case that the cleaning member 33 cleans the to-be-cleaned surface, the cleaning member 33 is in contact with the to-be-cleaned surface and cleans the to-be-cleaned surface by rotating, vibrating or the like. In the process of rotating the cleaning member 33, the cleaning member 33 can move relative to the to-be-cleaned surface, so that the cleaning member 33 can roll or wipe away the dirt on the to-be-cleaned surface to keep the to-be-cleaned surface clean. The dirt herein can include liquid dirt, solid dirt and solid-liquid mixed dirt.

[0054] The driving member 35 is a structure in the cleaning module 30 for driving the cleaning member 33 to move. Specifically, in some embodiments, the driving member 35 can be connected with the cleaning member 33, and in the case that the driving member 35 normally operates, the driving force of the driving member 35 can be transmitted to the cleaning member 33 to make the cleaning member 33 rotate relative to the body 10. It should be noted that the driving member 35 can include a driving structure such as a motor or an electric push rod. The motor includes but is not limited to a direct current servo motor, an alternating current servo motor, a stepper motor and the like.

[0055] It can be understood that, in the case that the cleaning member 33 is a track-type cleaning member, the driving member 35 can adopt a motor with larger power to ensure the stability of the rotation cleaning of the cleaning member 33. However, the motor with larger power generates more heat during operation, and is more likely to cause heat accumulation to damage the driving member 35. Thus, in some embodiments of the present disclosure, at least part of the driving member 35 corresponds to the heat dissipation hole 107, so that the suction airflow flows from the first air duct 106 to the driving member 35 through the heat dissipation hole 107, and carries away the heat on the surface of the driving member 35, thereby achieving heat dissipation of the driving member 35 and ensuring that the driving member 35 will not be damaged due to overheating caused by heat accumulation. In the embodiments of the present disclosure, the heat dissipation mode of the driving member 35 is relatively simple, and the suction function of the suction member 60 can be fully utilized, thereby achieving efficient use of resources, and the heat dissipation device for the driving member 35 does not need to be separately arranged, so that the production cost can be reduced, the number of components of the cleaning robot 100 can be reduced, and the structural design of the cleaning robot 100 can be simplified.

[0056] In the cleaning robot 100 of the embodiments of the present disclosure, in the case that the suction member 60 works and generates the suction airflow in the first air duct 106, the suction airflow passes through the part of the heat dissipation member 73 extending into the first air duct 106 to achieve heat dissipation of the control assembly 71, and the suction airflow can also flow to the driving member 35 through the heat dissipation hole 107 to achieve heat dissipation of the driving member 35, that is, the suction member 60 can simultaneously achieve heat dissipation of the control assembly 71 and the driving member 35, thereby on the one hand, preventing the control assembly 71 or the driving member 35 from being damaged due to overheating caused by heat accumulation, and ensuring the stability and reliability of the working of the cleaning robot 100; on the other hand, the heat dissipation device for the control assembly 71 or the driving member 35 does not need to be additionally arranged, so that the production cost can be reduced, the number of components of the cleaning robot 100 can be reduced, and the structural design of the cleaning robot 100 can be simplified.

[0057] The cleaning robot 100 will be described in detail below with reference to the accompanying drawings.

[0058] Please refer to Figures 2 to 4 In some embodiments, the first air duct 106 includes an air inlet duct 1061 and an air outlet duct 1063, the air inlet duct 1061 is in communication with the air inlet of the suction member 60 and is located at the front side of the suction member 60, that is, the air inlet duct 1061 is located in the front region of the suction member 60, the air outlet duct 1063 is in communication with the air outlet of the suction member 60 and is located at the rear side of the suction member 60, that is, the air outlet duct 1063 is located in the rear region of the suction member 60. The heat dissipation hole 107 is in communication with the air outlet duct 1063, at least part of the driving member 35 corresponds to the heat dissipation hole 107, and at least part of the heat dissipation member 73 is arranged in the air inlet duct 1061.

[0059] Exemplarily, at least part of the driving member 35 corresponds to the heat dissipation hole 107, including but not limited to the following cases:

[0060] The heat dissipation hole 107 is opposite to the overall structure of the driving member 35, so that in the case that the suction airflow flows to the driving member 35 through the heat dissipation hole 107, the suction airflow can contact most of the structure of the driving member 35, thereby achieving uniform heat dissipation of the driving member 35 and improving the heat dissipation effect;

[0061] The heat dissipation hole 107 is opposite to part of the structure of the driving member 35, for example, the main heat source (when the driving member 35 is a motor, it can be the winding of the motor, etc.) of the driving member 35 is opposite to the heat dissipation hole 107, so that the suction airflow can be targeted to the driving member 35 for heat dissipation, thereby improving the heat dissipation efficiency;

[0062] The heat dissipation hole 107 corresponds to the side part (for example, the top or bottom of the driving member 35 in the height direction Z of the machine body 10, and for example, one end or one side wall of the driving member 35 in the front-rear direction or the left-right direction Y of the machine body 10) of the driving member 35, and in the case that the suction airflow flows to the driving member 35 through the heat dissipation hole 107, the suction airflow can carry away the heat emitted around the driving member 35, thereby achieving heat dissipation of the driving member 35;

[0063] The driving member 35 can include a heat transfer part corresponding to the heat dissipation hole 107, and in the case that the suction airflow flows to the heat transfer part through the heat dissipation hole 107, the suction airflow can carry away the heat on the heat transfer part to achieve heat dissipation of the driving member 35. The heat transfer part can be made of materials with good heat conductivity, such as aluminum, copper, aluminum nitride, silicon carbide, etc.

[0064] Therefore, the heat dissipation member 73 is arranged at the air inlet duct 1061, and the heat dissipation hole 107 is arranged at the air outlet duct 1063, so that compared with the case that the heat dissipation member 73 and the heat dissipation hole 107 are both arranged at the air inlet duct 1061 or both arranged at the air outlet duct 1063, the heat dissipation member 73 and the heat dissipation hole 107 in the present disclosure are far apart, so that the airflow heat from the heat dissipation member 73 cannot directly flow to the heat dissipation hole 73, thereby avoiding that the suction airflow excessively conducts the heat of the heat dissipation member 73 to the driving member 35 through the heat dissipation hole 107, and further ensuring the heat dissipation effect of the suction airflow on the driving member 35.

[0065] Further, in some embodiments, the body 10 is provided with an air outlet 19, which is in communication with the air outlet air duct 1063, so that the suction air flow can flow out of the air outlet 19 to the outside, so as to dissipate the heat carried to the outside environment. For example, the air outlet 19 is arranged on the side wall between the left side and the rear side of the body 10. In some embodiments of the present disclosure, the air outlet 19 includes at least one. In one example, the air outlet 19 includes one, and a filter screen is arranged at the air outlet 19, so as to prevent impurities from the outside from entering the first air duct 106 through the air outlet 19 to damage the suction member 60 or other structures, and ensure the stability and reliability of the operation of the suction member 60. In another example, the air outlet 19 includes a plurality of air outlets 19, which are arranged at intervals and are used together to allow the suction air flow to flow out to the outside.

[0066] Please refer to Figure 5 In some embodiments, a sealing member 77 is arranged between the heat dissipation member 73 and the air inlet air duct 1061, and the sealing member 77 is used to seal the gap between the heat dissipation member 73 and the air inlet air duct 1061. It should be noted that, in some embodiments, the sealing member 77 includes but is not limited to rubber, silicone or foam, etc.

[0067] The arrangement of the sealing member 77 can prevent the suction air flow from flowing out of the first air duct 106 through the gap between the heat dissipation member 73 and the air inlet air duct 1061, so as to ensure the suction force of the suction member 60 on the dirt cleaned by the roller brush module 41, and ensure the cleaning effect of the cleaning robot 100 on the surface to be cleaned.

[0068] Please refer to Figure 2 、 Figure 3 and Figure 5 , and combine Figure 6 and Figure 7 In some embodiments, the heat dissipation member 73 includes a heat dissipation body 731 and a shielding portion 733 connected to the heat dissipation body 731, the shielding portion 733 protrudes and extends from the heat dissipation body 731 towards the main control board 711, and abuts against the main control board 711, the chip 713 is located in a shielding space 710 surrounded by the heat dissipation body 731, the shielding portion 733 and the main control board 711, and a shielding member 75 is arranged on the outer peripheral wall of the shielding portion 733, and the shielding member 75 is used to prevent electromagnetic radiation from entering and exiting the shielding space 710.

[0069] Specifically, in some embodiments, the heat dissipation body 731, the shielding part 733 and the main control board 711 can jointly form a closed shielding space 710, and the chip 713 is located in the shielding space 710. In this way, the shielding space 710 can protect the chip 713 and reduce the possibility of damage to the chip 713. In addition, the shielding part 75 can make the shielding space 710 have the effect of electromagnetic shielding, block electromagnetic radiation in and out of the shielding space 710, protect the chip 713 and other elements from electromagnetic interference, and improve the stability and reliability of the working of the control assembly 71. It should be noted that, in some embodiments, the shielding part 75 can be a conductive cloth or the like. The conductive cloth is a material that uses fiber cloth (such as cotton, polyester, etc.) as the basis and is specially treated to have conductive properties on the surface. Of course, in other embodiments, the shielding part 75 can also be any structure having an electromagnetic shielding function, and the present disclosure does not make any limitation.

[0070] It can be understood that, in the present disclosure, no additional separate shielding device is needed to shield the chip 713, thereby reducing the number of parts of the cleaning robot 100 and simplifying the structural design of the cleaning robot 100 while reducing the production cost.

[0071] In some embodiments of the present disclosure, a heat conduction part can be arranged between the chip 713 and the heat dissipation body 731. The heat conduction part can improve the heat conduction efficiency between the chip 713 and the heat dissipation body 731, thereby improving the heat dissipation effect. It should be noted that, in some embodiments, the heat conduction part can be a heat-conducting silicone grease or other element with good heat conduction performance, and the present disclosure does not make any limitation.

[0072] Please refer to Figure 6 and Figure 7 In some embodiments, the heat dissipation part 73 further includes a support part 735 connected to the heat dissipation body 731. The support part 735 extends outward from the heat dissipation body 731 towards the main control board 711 and is connected to the main control board 711. The support part 735 and the main control board 711 can be combined together by welding or bolt connection, etc. In this way, the connection between the heat dissipation part 73 and the main control board 711 can be achieved. In some embodiments of the present disclosure, the support part 735 can include at least two support parts 735 which are arranged at intervals on the heat dissipation body 731. In this way, the stability of the connection between the heat dissipation part 73 and the main control board 711 can be improved.

[0073] and / or, please refer to Figure 7In some embodiments, the heat dissipation member 73 further comprises a heat dissipation portion 737 connected to the heat dissipation body 731. The heat dissipation portion 737 is arranged in the air inlet air duct 1061 and protrudes from the heat dissipation body 731 towards the air inlet air duct 1061. The arrangement of the heat dissipation portion 737 can increase the contact area between the heat dissipation member 73 and the suction air flow, thereby improving the heat dissipation efficiency and enhancing the heat dissipation effect of the control assembly 71 on the heat dissipation member 73. It can be understood that, in some embodiments, the heat dissipation portion 737 comprises a plurality of heat dissipation portions 737 arranged on the heat dissipation body 731 at intervals.

[0074] Referring to Figures 1 to 3 In some embodiments, the air inlet air duct 1061 is arranged between the left side 103 of the machine body 10 and the front side 101 of the machine body 10, i.e., the air inlet air duct 1061 is arranged in the region between the left side and the front side of the machine body 10. In this way, it can be ensured that the air inlet air duct 1061 can communicate with the air inlet of the suction member 60 and the dirt storage cavity 47, so that the suction member 60 can suck the dirt cleaned by the roller brush module 41 into the dirt storage cavity 47. In addition, compared with the arrangement of the air inlet air duct 1061 between the right side 104 of the machine body 10 and the front side 101 of the machine body 10, the arrangement of the air inlet air duct 1061 in the present disclosure can shorten the flow distance of the suction air flow, thereby improving the suction efficiency of the suction member 60 and ensuring the cleaning effect of the cleaning robot 100.

[0075] In some embodiments, the air outlet air duct 1063 is arranged between the left side 103 of the machine body 10 and the rear side 102 of the machine body 10, i.e., the air outlet air duct 1063 is arranged in the region between the left side and the rear side of the machine body 10. In this way, it can be ensured that the air outlet air duct 1063 can communicate with the air outlet of the suction member 60 and the external atmosphere, so as to ensure the normal operation of the suction member 60. In addition, compared with the arrangement of the air outlet air duct 1063 between the right side 104 of the machine body 10 and the rear side 102 of the machine body 10, the arrangement of the air inlet air duct 1061 in the present disclosure can shorten the flow distance of the suction air flow, thereby improving the suction efficiency of the suction member 60 and ensuring the cleaning effect of the cleaning robot 100.

[0076] In some embodiments, the machine body 10 comprises a middle frame 11 and a first housing 13. At least part of the cleaning module 30, the suction member 60, the control module 70 and the heat dissipation hole 107 are arranged on the middle frame 11. The first housing 13 is connected to the middle frame 11 and forms a first air duct 106 together with the middle frame 11. For example, the first housing 13 is arranged on the middle frame 11, so that the suction air flow flows in the space between the first housing 13 and the middle frame 11.

[0077] Compared with the scheme without the first shell 13, the first air duct 106 can be formed by the upper cover 17 and the middle frame 11 of the cleaning robot together, or by some shell structure located between the middle frame 11 and the upper cover 17 and the middle frame 11 together, the first air duct 106 formed thereby is a relatively divergent space without a fixed shape, the flow path of the suction airflow flowing therein is also relatively divergent without a fixed direction, and is also easy to leak from the gaps existing therein, which is not conducive to the heat dissipation function of the suction airflow; wherein, the setting of the first shell 13 can make the suction airflow formed when the suction member 60 works flow along a predetermined path, facilitate the control of the direction of the suction airflow and avoid its diffusion to the surroundings, so as to achieve effective heat dissipation of the suction airflow to the control assembly 71 and the driving member 35, prolong the service life of the control assembly 71 and the driving member 35, and ensure the normal work of the cleaning robot 100.

[0078] In some embodiments of the present disclosure, a closure can be provided between the first shell 13 and the middle frame 11, which can seal the gap between the first shell 13 and the middle frame 11, so that the first shell 13 and the middle frame 11 can jointly form a closed first air duct 106 to prevent the suction airflow from leaking, thereby on the one hand, the suction function of the suction member 60 to the dirt can be ensured, and the cleaning effect of the cleaning robot 100 can be improved; on the other hand, the noise generated by the leakage of the suction airflow can be prevented, and the user experience can be improved. It should be noted that the first air duct 106 in the present disclosure can be irregularly shaped as shown, which can adapt to the structural layout of the cleaning robot 100, and facilitate the compact arrangement of other components. Figure 3

[0079] For example, a recess can be provided on the middle frame 11, the recess is recessed from the top of the middle frame 11 (the side of the middle frame 11 away from the cleaning surface when the cleaning robot 100 is carried on the cleaning surface) towards the cleaning surface, and the first shell 13 is provided at the opening of the recess and jointly forms the first air duct 106 with the middle frame 11. Wherein, the setting of the first shell 13 can play a decorative effect on the body 10, reduce the visual defects of the body 10, and improve the aesthetic appearance of the body 10.

[0080] In some embodiments, the first shell 13 can be an integral structure, the first shell 13 is connected with the middle frame 11 and jointly forms the first air duct 106. In other embodiments, the first shell 13 can be a split structure, for example, the first shell 13 can include a first sub-shell and a second sub-shell. Wherein, the first sub-shell is connected with the middle frame 11 and jointly forms the air inlet duct 1061, and the second sub-shell is connected with the middle frame 11 and jointly forms the air outlet duct 1063.

[0081] ​In some embodiments, the middle frame 11 and the first shell 13 can be an integral structure, i.e., the middle frame 11 and the first shell 13 are an integral structure made by an integral molding process, so as to improve the bonding strength of the middle frame 11 and the first shell 13, ensure the sealing of the first air duct 106, prevent the middle frame 11 and the first shell 13 from separating during the cleaning process of the cleaning robot 100, and ensure the normal operation of the cleaning robot 100. In other embodiments, the middle frame 11 and the first shell 13 can be a split structure, i.e., the middle frame 11 and the first shell 13 are two different structures, so as to facilitate the assembly of structures such as the suction member 60 on the middle frame 11 and improve assembly efficiency. The middle frame 11 and the first shell 13 can be combined together by a detachable connection or a non-detachable connection. The detachable connection includes but is not limited to clamping or bolt connection, etc.; the non-detachable connection includes but is not limited to bonding or welding, etc.

[0082] Please refer to Figure 1 and Figure 2 In some embodiments, the rear side 102 of the body 10 is provided with a mounting groove 105, the opening of the mounting groove 105 faces the rear side 102 of the body 10, and the radar 25 is arranged in the mounting groove 105. The detection signal of the radar 25 is emitted through the opening of the mounting groove 105, and the radar 25 is used to detect the surrounding environment of the cleaning robot 100.

[0083] Specifically, in some embodiments, the mounting groove 105 can be a groove recessed from the side wall of the rear side 102 of the body 10 to the inside of the body 10, and the mounting groove 105 is spaced apart from the top wall of the body 10 in the height direction Z of the body 10. It should be noted that the forward direction X of the cleaning robot 100 is substantially perpendicular to the height direction Z of the body 10. "Substantially perpendicular" means that the angle between the two is 90°±5° within the allowable range of manufacturing process or assembly process error.

[0084] In some embodiments of the present disclosure, the edge of the opening of the mounting groove 105 is provided with a rounded corner, which can reduce the scratch on the user when installing the radar 25 or other structural members, and facilitate the assembly of the radar 25 and other structural members in the mounting groove 105. On the other hand, it can reduce the visual defects of the opening of the mounting groove 105 and improve the aesthetics of the cleaning robot 100.

[0085] In some embodiments of the present disclosure, the opening angle of the slot of the mounting slot 105 is greater than the field of view angle of the radar 25, so that on the one hand, the detection range of the radar 25 can be prevented from being limited due to the opening angle of the slot of the mounting slot 105 being too small, thereby reducing the possibility of the cleaning robot 100 having a detection blind area and improving the stability and reliability of the cleaning robot 100; on the other hand, the radar 25 can be effectively utilized, and resource waste can be reduced. It should be noted that the radar 25 in the present embodiment can be a radar without a 360° field of view angle.

[0086] In some embodiments of the present disclosure, the opening angle of the slot of the mounting slot 105 is less than 240°, so that the detection range of the cleaning robot 100 on the rear side 102 of the body 10 can be ensured, while the size of the mounting slot 105 is prevented from being too large to cause the structural strength of the body 10 to be too small, thereby reducing the possibility of the body 10 being deformed and damaged and prolonging the service life of the body 10. It should be noted that the radar 25 in the present embodiment can be a radar without a 360° field of view angle or a radar with a 360° field of view angle.

[0087] The radar 25 is a component of the cleaning robot 100 for obtaining the surrounding environment information of the rear side 102 of the body 10. The radar 25 includes but is not limited to a laser radar, a pulse radar, a continuous wave radar, etc. Compared with the radar 25 being arranged on the top of the cleaning robot 100 and protruding from the body 10 of the cleaning robot 100, the arrangement manner of the radar 25 in the present disclosure does not occupy the space in the height direction Z of the cleaning robot 100, so that the height of the cleaning robot 100 can be reduced, the cleaning robot 100 can enter a narrow space such as the bottom of a bed or a sofa to clean, the applicability of the cleaning robot 100 is improved, and the use requirements of the user can be effectively met.

[0088] In addition, since the cleaning motion of the cleaning robot 100 usually includes advancing and rotating, when the radar 25 is placed on the rear side 102 of the body 10, the cleaning robot 100 will not collide with obstacles during the cleaning process, and a protection mechanism does not need to be arranged for the radar 25, so that not only the production cost can be reduced and the industry competitiveness of the cleaning robot 100 can be improved, but also the space occupation of the body 10 can be reduced, and the size design of other structural components of the cleaning robot 100 is facilitated. Moreover, compared with the radar 25 being arranged on the front side 101 of the body 10 or the right side 104 of the body 10, when the radar 25 is placed on the rear side 102 of the body 10, the rear side 102 of the body 10 does not have a detection blind area, and the possibility of collision of the cleaning robot 100 when retreating is effectively reduced.

[0089] For example, when the radar 25 is arranged on the top of the body 10, if the cleaning robot 100 needs to enter the base station 300 (as shown in FIG. 4), the radar 25 can be placed on the rear side 102 of the body 10, so that the radar 25 does not need to be removed, and the cleaning robot 100 can enter the base station 300 without any obstacles. Figure 8When the cleaning robot 100 needs to enter the base station 300 for maintenance, the cleaning robot 100 can enter the base station 300 in a backward posture, and the cleaning robot 100 needs to rely on the infrared sensor to realize positioning of entering and exiting the base station 300, that is, the cleaning robot 100 is provided with an infrared sensor, and the base station 300 is provided with a reflective sticker or other structural member capable of cooperating with the infrared sensor, thereby resulting in a relatively high cost. In some embodiments of the present disclosure, the radar 25 is arranged at the rear side 102 of the body 10, so that when the cleaning robot 100 needs to enter the base station 300, the cleaning robot 100 can directly use the radar 25 to realize positioning of entering and exiting the base station 300, which is lower in cost than adding an infrared sensor, and is helpful to improve the competitiveness of the industry.

[0090] Please refer to Figure 3 and Figure 4 In some embodiments, the body 10 is further provided with a second air duct 108, which is in communication with the mounting groove 105 and the heat dissipation hole 107. In the case that the suction member 60 works and generates a suction air flow, the suction air flow flows to the mounting groove 105 through the heat dissipation hole 107 and the second air duct 108, so as to dissipate heat of the radar 25.

[0091] Specifically, in some embodiments, the heat dissipation hole 107 is in communication with the air outlet air duct 1063. In the case that the suction member 60 works and generates a suction air flow in the first air duct 106, the suction air flow can not only dissipate heat of the control assembly 71 and the driving member 35, but also flow to the mounting groove 105 through the heat dissipation hole 107 and the second air duct 108, so as to dissipate heat of the radar 25 in the mounting groove 105. Therefore, it is possible to prevent the heat generated by the radar 25 from being accumulated to cause overheating damage, and prevent the heat of the radar 25 from adversely affecting other structural members of the cleaning robot 100, thereby prolonging the service life of the radar 25 and improving the stability and reliability of the operation of the radar 25. In addition, the heat dissipation of the radar 25 by the suction air flow generated by the suction member 60 is a relatively simple heat dissipation mode, which can fully utilize the suction function of the suction member 60, realize efficient use of resources, and does not need to separately arrange a heat dissipation device to dissipate heat of the radar 25. Therefore, it is possible to reduce the production cost while reducing the number of parts of the cleaning robot 100 and simplifying the structural design of the cleaning robot 100.

[0092] In some embodiments, the body 10 includes a middle frame 11 and a second housing 15. At least part of the cleaning module 30, the suction member 60, the control module 70, and the heat dissipation hole 107 are arranged in the middle frame 11. The second housing 15 is connected with the middle frame 11 and forms the second air duct 108 together. For example, the second housing 15 is arranged on the middle frame 11, so that the suction air flow flows in the space between the second housing 15 and the middle frame 11.

[0093] Compared with the scheme without the second shell 15, the second air duct 108 can be formed by the upper cover 17 and the middle frame 11 of the cleaning robot jointly, or be formed by some shell structure located between the middle frame 11 and the upper cover 17 and the middle frame 11 jointly, the second air duct 108 formed thereby is a relatively divergent space without fixed shape, the flow path of the suction airflow flowing therein is also relatively divergent without fixed direction, and is also easy to leak from the gaps existing therein, which is not conducive to the heat dissipation function of the suction airflow; wherein, the arrangement of the second shell 15 can make the suction airflow formed when the suction member 60 works flow along the preset path, thereby being able to realize effective heat dissipation of the suction airflow to the radar 25, prolong the service life of the radar 25, and ensure the normal work of the cleaning robot 100.

[0094] In some embodiments of the present disclosure, a sealing member can be arranged between the second shell 15 and the middle frame 11, the sealing member being capable of sealing the gap between the second shell 15 and the middle frame 11, so that the second shell 15 and the middle frame 11 can jointly form a closed second air duct 108 to prevent the suction airflow from leaking, thereby being able to prevent noise caused by the leakage of the suction airflow, and improving the user experience.

[0095] In some embodiments, the middle frame 11 and the second shell 15 can be an integral structure, that is, the middle frame 11 and the second shell 15 are an integral structure made by using an integral molding process, so that the bonding strength of the middle frame 11 and the second shell 15 can be improved, the separation of the middle frame 11 and the second shell 15 during the cleaning process of the cleaning robot 100 can be prevented, and the normal work of the cleaning robot 100 can be ensured. In other embodiments, the middle frame 11 and the second shell 15 can be a split structure, that is, the middle frame 11 and the second shell 15 are two different structures, so that the assembly of the suction member 60 and other structures on the middle frame 11 can be facilitated, and the assembly efficiency can be improved. The middle frame 11 and the second shell 15 can be combined together by using a detachable connection mode or a non-detachable connection mode. The detachable connection mode includes but is not limited to clamping or bolt connection, etc.; the non-detachable connection mode includes but is not limited to bonding or welding, etc.

[0096] Please refer to Figure 1 , Figure 2 and Figure 8 , the present disclosure also provides a cleaning system 1000, comprising the cleaning robot 100 according to any one of the above embodiments and the base station 300 cooperating with the cleaning robot 100, the base station 300 comprising a parking position 301 for accommodating the cleaning robot 100.

[0097] The base station 300 is a device capable of maintaining the cleaning robot 100. It can be understood that, in some embodiments, the base station 300 can implement maintenance of the cleaning robot 100 when the cleaning robot 100 is located at the docking position 301 of the base station 300, and the type of maintenance includes but is not limited to charging, dust collection, cleaning and washing of cleaning components, replenishment of clean water, and extraction of dirty water.
