Cleaning robots and cleaning systems

[0001] Cross-reference to related applications

[0002] This disclosure claims priority to Chinese Patent Application No. 202423192912.1, filed on October 20, 2024, entitled "Cleaning Robot and Cleaning System", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of cleaning technology, and more specifically, to a cleaning robot and a cleaning system. Background Technology

[0004] A cleaning robot is a device used to automatically clean carpets or floors, typically used in home cleaning and large-scale venue cleaning. In related technologies, some components of a cleaning robot generate heat during operation, such as control and drive components. The control component regulates the robot's operation, while the drive component moves its moving parts. If the cleaning robot cannot dissipate heat from these components in a timely manner, the heat will accumulate, causing overheating and damage, thus affecting the robot's normal operation.

[0005] Utility Model Content

[0006] This disclosure provides a cleaning robot and cleaning system to solve at least one of the aforementioned technical problems.

[0007] In a first aspect, this disclosure provides a cleaning robot. The cleaning robot includes a body, a first air duct, heat dissipation holes, a suction component, a control module, and a cleaning module. Along the forward direction of the cleaning robot, the body includes opposing front and rear sides, and along the width direction of the body, it includes opposing left and right sides. The first air duct is located on the left side of the body. The heat dissipation holes are located on the body and behind the first air duct, communicating with the first air duct. The suction component is located between the left side and the rear side of the body, communicating with the first air duct. The control module is located on the body and to the right of the first air duct. The control module controls the operation of the cleaning robot and includes a control component and a heat dissipation component. The heat dissipation component is connected to the control component and at least partially extends into the first air duct. The cleaning module is located on the rear side of the body. The cleaning module includes a cleaning component and a driving component. The driving component drives the cleaning component to move relative to the surface to be cleaned, and is located behind the heat dissipation holes. When the suction component is operating and generating a suction airflow in the first air duct, the suction airflow passes through the portion of the heat dissipation component extending into the first air duct to dissipate heat from the control components. The suction airflow also flows through the heat dissipation holes to the driving component to dissipate heat from the driving component.

[0008] In some embodiments, the first air duct includes an air inlet duct and an air outlet duct. The air inlet duct is connected to the air inlet of the suction member and is located on the front side of the suction member. The air outlet duct is connected to the air outlet of the suction member and is located on the rear side of the suction member. The heat dissipation hole is connected to the air outlet duct. At least a portion of the driving member corresponds to the heat dissipation hole. At least a portion of the heat dissipation member is disposed in the air inlet duct.

[0009] In some embodiments, the control component includes a main control board and a chip disposed on the main control board. The heat sink includes a heat sink body and a shielding portion connected to the heat sink body. The shielding portion protrudes from the heat sink body toward the main control board and abuts against the main control board. The chip is located within the shielded space formed by the heat sink body, the shielding portion, and the main control board.

[0010] In some embodiments, a shielding element is provided on the outer peripheral wall of the shielding portion, the shielding element being used to prevent electromagnetic radiation from entering or leaving the shielding space.

[0011] In some embodiments, the heat sink further includes a support portion connected to the heat sink body, the support portion extending protruding from the heat sink body toward the main control board and connected to the main control board.

[0012] In some embodiments, the heat sink further includes a heat dissipation portion connected to the heat sink body, the heat dissipation portion being disposed in the air inlet duct and extending protruding from the heat sink body toward the air inlet duct.

[0013] In some embodiments, a sealing element is provided between the heat sink and the air inlet duct, the sealing element being used to seal the gap between the heat sink and the air inlet duct.

[0014] In some embodiments, the housing includes a mid-frame and a first housing. At least a portion of the cleaning module, the suction component, the control module, and the heat dissipation holes are disposed on the mid-frame. The first housing is connected to the mid-frame and together form the first air duct.

[0015] In some embodiments, a mounting slot is provided on the rear side of the robot body, with the slot opening facing the rear of the robot body. A radar is installed in the mounting slot, and the radar is used to detect the surrounding environment of the cleaning robot. The robot body also has a second air duct, which is connected to the mounting slot and the heat dissipation holes. When the suction component is working and generating a suction airflow, the suction airflow flows through the heat dissipation holes and the second air duct to the mounting slot to dissipate heat from the radar.

[0016] In some embodiments, the housing includes a mid-frame and a second housing. At least a portion of the cleaning module, the suction component, the control module, and the heat dissipation holes are disposed on the mid-frame. The second housing is connected to the mid-frame and together form the second air duct.

[0017] Secondly, this disclosure provides a cleaning system. The cleaning system includes a cleaning robot and a base station. The base station is used in conjunction with the cleaning robot and includes a docking position for accommodating the cleaning robot. The cleaning robot includes a body, a first air duct, heat dissipation holes, a suction component, a control module, and a cleaning module. Along the forward direction of the cleaning robot, the body includes opposing front and rear sides; along the width direction of the body, the body includes opposing left and right sides. The first air duct is located on the left side of the body. The heat dissipation holes are located on the body and behind the first air duct, communicating with the first air duct. The suction component is located between the left side and the rear side of the body and communicates with the first air duct. The control module is located on the body and to the right of the first air duct. The control module controls the operation of the cleaning robot and includes a control component and a heat dissipation component. The heat dissipation component is connected to the control component and at least partially extends into the first air duct. The cleaning module is located on the rear side of the body. The cleaning module includes a cleaning component and a driving component. The driving component drives the cleaning component to move relative to the surface to be cleaned, and is located behind the heat dissipation holes. When the suction component is operating and generating a suction airflow in the first air duct, the suction airflow passes through the portion of the heat dissipation component extending into the first air duct to dissipate heat from the control components. The suction airflow also flows through the heat dissipation holes to the driving component to dissipate heat from the driving component.

[0018] In the cleaning robot and cleaning system of this disclosure, when the suction component is working and generating a suction airflow in the first air duct, the suction airflow passes through the portion of the heat sink extending into the first air duct to dissipate heat from the control component. Furthermore, the suction airflow can also flow through the heat dissipation holes to the drive component to dissipate heat from the drive component. That is, the suction component can simultaneously dissipate heat from both the control component and the drive component. This prevents overheating damage to the control component or drive component due to heat accumulation, ensuring the stability and reliability of the cleaning robot's operation. On the other hand, it eliminates the need for additional heat dissipation devices for the control component or drive component, thereby reducing production costs, decreasing the number of parts in the cleaning robot, and simplifying its structural design.

[0036] In related technologies, during the operation of a cleaning robot, some components generate heat, such as control components and drive components. The control components control the operation of the cleaning robot, and the drive components drive the movement of the cleaning robot's moving parts. However, if the cleaning robot cannot dissipate heat from these components in a timely manner, the heat will accumulate, causing the components to overheat and become damaged, thus affecting the normal operation of the cleaning robot. To solve this problem, this disclosure provides a cleaning robot 100 (shown in FIG. 1) and a cleaning system 1000 (shown in FIG. 8).

[0037] Referring to Figures 1 and 2, and in conjunction with Figures 3 and 4, this disclosure provides a cleaning robot 100. The cleaning robot 100 includes a body 10, a first air duct 106, a heat dissipation hole 107, a suction component 60, a control module 70, and a cleaning module 30. Along the forward direction X of the cleaning robot 100, the body 10 includes a front side 101 and a rear side 102 opposite to each other. Along the width direction Y of the body 10, the body 10 includes a left side 103 and a right side 104. The first air duct 106 is disposed on the left side 103 of the body 10. The heat dissipation hole 107 is disposed on the body 10 and located behind the first air duct 106, and the heat dissipation hole 107 communicates with the first air duct 106. The suction component 60 is disposed between the left side 101 and the rear side 102 of the body 10, and the suction component 60 communicates with the first air duct 106. A control module 70 is disposed on the body 10 and located on the right side of the first air duct 106. The control module 70 is used to control the operation of the cleaning robot 100. The control module 70 includes a control component 71 and a heat sink 73. The heat sink 73 is connected to the control component 71 and extends at least partially into the first air duct 106. A cleaning module 30 is disposed on the rear side 102 of the body 10. The cleaning module 30 includes a cleaning component 33 and a driving component 35. The driving component 35 is used to drive the cleaning component 33 to move relative to the surface to be cleaned to clean the surface. The driving component 35 is located behind the heat dissipation hole 107. When the suction component 60 is working and generates a suction airflow in the first air duct 106, the suction airflow is used to dissipate heat from the heat sink 73 to dissipate heat from the control component 71. The suction airflow flows through the heat dissipation hole 107 to the driving component 35 to dissipate heat from the driving component 35.

[0038] It is understood that a cleaning robot 100 is an intelligent device capable of performing functions such as sweeping, vacuuming, and mopping. Cleaning robots 100 include, but are not limited to, sweeping robots, mopping robots, combined sweeping and mopping robots, intelligent robots, and mobile robots. Mopping robots can be used to wipe and clean surfaces, while combined sweeping and mopping robots can be used to both sweep and wipe surfaces. It should be noted that, in one example, the surface to be cleaned can be the floor inside a building. In another example, the surface to be cleaned can be the surface of an object such as a wall, window, bed, floor, marble, or carpet.

[0039] The body 10 is a component of the cleaning robot 100 used to load and protect other components (including but not limited to the suction component 60, control module 70, and cleaning module 30). The body 10 can be made of metallic and / or non-metallic materials. Metallic materials include but are not limited to aluminum, iron, steel, or aluminum alloys, while non-metallic materials include but are not limited to plastics.

[0040] The orientations described in this embodiment are defined with the cleaning robot 100 mounted on the surface to be cleaned. "Front side 101", "Rear side 102", "Left side 103", and "Right side 104" are all relative to the forward direction X of the cleaning robot 100. When the cleaning robot 100 moves forward along the forward direction X, the frontmost point of the body 10 closest to the forward direction X is the front side 101 of the body 10, or, with the center point of the body 10 as the dividing line, the area on the body 10 closest to the frontmost point of the forward direction X is the front side 101 of the body 10; the rearmost point of the body 10 closest to the forward direction X is the rear side 102 of the body 10, or, with the center point of the body 10 as the dividing line, the area on the body 10 closest to the rearmost point of the forward direction X is the rear side 102 of the body 10; when the cleaning robot 100 moves forward along the forward direction X, viewed from above... For robot 100, the leftmost point of the body 10 closest to the leftmost point in the width direction is the left side 103 of the body 10. Alternatively, with the center point of the body 10 as the dividing line, the area of ​​the body 10 closest to the leftmost point in the width direction is the left side 103 of the body 10. When the cleaning robot 100 moves forward in the forward direction X, looking down at the cleaning robot 100, the rightmost point of the body 10 closest to the rightmost point in the width direction is the right side 104 of the body 10. Alternatively, with the center point of the body 10 as the dividing line, the area of ​​the body 10 closest to the rightmost point in the width direction is the right side 103 of the body 10. In other words, "front side 101", "rear side 102", "left side 103" and "right side 104" can be either a side wall or an end of the body 10 of the cleaning robot 100 in the corresponding position, or a region of the body 10 of the cleaning robot 100 in the corresponding position.

[0041] For example, for a cleaning robot 100 with a regular shape, the center point of the body 10 can be the center point of that regular shape; for example, the center of a circular body 10 is the center of the circle. For a cleaning robot 100 with an irregular shape, the center point of the body 10 can be the location of the center of gravity of the cleaning robot 100. It should be noted that the shape of the cleaning robot 100 defined in this disclosure is a shape that is approximately close to a certain shape (such as approximately circular), and is not an absolutely standard geometric shape.

[0042] Similarly, taking the forward direction X of the cleaning robot 100 as a reference direction, the rear side of the first air duct 106 can be the area located behind the first air duct 106, or it can be the rearmost end of the first air duct 106 that is closest to the forward direction X of the cleaning robot 100; the right side of the first air duct 106 can be the area located on the right side of the first air duct 106, or it can be the rightmost end of the first air duct 106 that is closest to the width direction of the cleaning robot 100 when facing the front side 101 of the body 10.

[0043] The suction component 60 is a part of the cleaning robot 100 used to extract dirt by generating suction or negative pressure. In some embodiments of this disclosure, the cleaning robot 100 also includes a dirt collection chamber 47 (e.g., a dust box), which is disposed on the body 10 and is used to collect dirt swept by the roller brush module 41 (shown by dashed lines in FIG. 2, for example, the roller brush module 41 is located below the body 10 to contact the surface to be cleaned). The dirt can be liquid, solid (such as paper scraps or dust), or a mixture of solid and liquid, etc., and is not limited in this disclosure. Specifically, the first air duct 106 is in communication with the dirt collection chamber 47. While the roller brush module 41 is cleaning the surface to be cleaned, the suction component 60 operates and generates a suction airflow in the first air duct 106, enabling the roller brush module 41 to sweep dirt from the surface to be cleaned into the dirt collection cavity 47. The dirt collection cavity 47 collects and stores the dirt swept by the roller brush module 41, thereby preventing dirt from falling onto the cleaned surface and causing contamination, thus ensuring the cleaning effect of the cleaning robot 100. It should be noted that in some embodiments, the suction component 60 may be a fan, including but not limited to centrifugal fans, axial fans, and crossflow fans. In some embodiments of this disclosure, the fan may be an axial fan.

[0044] For example, a filter screen is provided between the first air duct 106 and the waste collection chamber 47. The filter screen can filter out dirt and grime to prevent dirt and grime from entering the first air duct 106 and causing damage to the suction component 60, thereby improving the stability and reliability of the suction component 60.

[0045] In the embodiments of this disclosure, the cleaning robot 100 can perform right-side edge cleaning, that is, the right side 104 of the robot body 10 can clean the edge of a wall or furniture. It is understood that when the cleaning robot 100 performs right-side edge cleaning, its center of gravity may shift to the right, potentially affecting its stability. Therefore, in some embodiments of the disclosure, the suction member 60 is positioned between the left side 103 and the rear side 102 of the robot body 10. This ensures that the center of gravity of the cleaning robot 100 is approximately centered when performing right-side edge cleaning, resulting in more even pressure from the cleaning member 33 on the surface to be cleaned, preventing localized overpressure or missed areas, and improving the stability and cleaning effect of the cleaning robot 100.

[0046] In addition, in some embodiments of this disclosure, the first air duct 106 is disposed on the left side 103 of the body 10. This facilitates the connection between the suction component 60 and the first air duct 106, shortens the flow formation of the suction airflow, reduces suction resistance, thereby improving the suction efficiency of the suction component 60 and ensuring the cleaning effect of the cleaning robot 100. On the other hand, it can prevent the cleaning module 30 from interfering with the first air duct 106 when the cleaning robot 100 cleans along the right side, ensuring the normal operation of the cleaning robot 100.

[0047] The control component 71 is a part 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, backward, and turning), plan and execute cleaning paths, and monitor the operating status of the cleaning robot 100. Referring to Figure 5, in some embodiments of this disclosure, the control component 71 includes a main control board 711 and a chip 713 disposed 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 achieve functions such as autonomous navigation, obstacle avoidance, and cleaning path planning, ensuring that the cleaning robot 100 can operate normally and efficiently and complete various cleaning tasks. Multiple chips 713 may be included. These multiple chips 713 may be sensor chips, storage chips, and drive control chips, etc., and are not limited thereto.

[0048] The heat sink 73 is a component capable of conducting, convection, or radiating heat from a heat source to the surrounding environment. The materials of the heat sink 73 include, but are not limited to, copper, aluminum, thermal grease, and thermal silicone. In some embodiments of this disclosure, the heat sink 73 is connected to the control component 71 and extends at least partially into the first air duct 106. Thus, the heat sink 73 can conduct heat from the control component 71 to the first air duct 106 through thermal conduction and remove heat using the suction airflow, thereby achieving heat dissipation for the control component 71 and ensuring that the control component 71 does not overheat and become damaged due to heat accumulation. The heat dissipation method for the control component 71 in the embodiments of this disclosure is relatively simple and can fully utilize the suction function of the suction component 60, achieving efficient resource utilization. This makes the heat sink 73 more efficient at dissipating heat from the control component 71, thereby reducing production costs, decreasing the number of parts in the cleaning robot 100, and simplifying the structural design of the cleaning robot 100.

[0049] Understandably, since chip 713 is a highly integrated electronic component containing a large number of transistors, resistors, capacitors, and other circuit elements, it generates a significant amount of heat during operation. This heat is difficult to dissipate effectively, potentially leading to overheating and damage. Therefore, in this disclosure, heat sink 73 can be connected to chip 713. This allows heat sink 73 to directly dissipate heat from chip 713, thereby improving heat dissipation efficiency and enhancing its heat dissipation effect on control component 71.

[0050] The cleaning module 30 is a module in the cleaning robot 100 that participates in cleaning the surface to be cleaned by providing dragging force. The cleaning component 33 is a part in the cleaning module 30 that specifically provides dragging force to clean the surface to be cleaned. In some embodiments of this disclosure, the cleaning component 33 is disposed on the body 10 and located at the bottom of the body 10 (the side of the body 10 facing the surface to be cleaned when the cleaning robot 100 is supported on it). Thus, when the cleaning robot 100 is in normal cleaning state, the cleaning component 33 can adhere closely to the surface to be cleaned to achieve the dragging function.

[0051] In one embodiment, the cleaning component 33 is a tracked cleaning component, in which case the cleaning robot 100 is a tracked cleaning robot. In another embodiment, the cleaning component 33 is a roller-type cleaning component, in which case the cleaning robot 100 is a roller-type cleaning robot. In still some embodiments, the cleaning component 33 can be a flatbed mop-type cleaning component or a disc-type cleaning component, in which case the cleaning robot 100 is a flatbed mop-type cleaning robot or a disc-type cleaning robot. Regardless of the type of cleaning component 33, when the cleaning component 33 cleans the surface to be cleaned, the cleaning component 33 is in contact with the surface to be cleaned and cleans the surface by means of rotation, vibration, etc. During the rotation of the cleaning component 33, the cleaning component 33 can move relative to the surface to be cleaned, so that the cleaning component 33 can roll away or wipe away the dirt on the surface to be cleaned, so that the surface to be cleaned remains clean. The dirt here can include liquid dirt, solid dirt, and solid-liquid mixture dirt.

[0052] The driving component 35 is a structure in the cleaning module 30 used to drive the cleaning component 33 to move. Specifically, in some embodiments, the driving component 35 can be connected to the cleaning component 33. When the driving component 35 is operating normally, the driving force of the driving component 35 can be transmitted to the cleaning component 33, causing the cleaning component 33 to rotate relative to the body 10. It should be noted that the driving component 35 may include a motor or an electric actuator, etc. The motor includes, but is not limited to, a DC servo motor, an AC servo motor, and a stepper motor.

[0053] It is understandable that when the cleaning component 33 is a tracked cleaning component, the driving component 35 can use a higher-power motor to ensure the stability of the cleaning component 33's rotation during cleaning. However, a higher-power motor generates more heat during operation, making it more prone to heat accumulation and damage to the driving component 35. Therefore, in some embodiments of this disclosure, at least a portion of the driving component 35 corresponds to the heat dissipation hole 107. Thus, the suction airflow flows from the first air duct 106 through the heat dissipation hole 107 to the driving component 35, carrying away the heat from the surface of the driving component 35, thereby achieving heat dissipation of the driving component 35 and ensuring that the driving component 35 will not be damaged by overheating due to heat accumulation. Among them, the heat dissipation method of the driving component 35 in the embodiments of this disclosure is relatively simple and can make full use of the suction function of the suction component 60, achieving efficient use of resources. There is no need to set up a separate heat dissipation device to dissipate heat from the driving component 35, thereby reducing production costs while reducing the number of parts in the cleaning robot 100 and simplifying the structural design of the cleaning robot 100.

[0054] In the cleaning robot 100 of this embodiment, when the suction component 60 is working and generates a suction airflow in the first air duct 106, the suction airflow passes through the portion of the heat dissipation component 73 that extends into the first air duct 106 to dissipate heat from the control component 71. The suction airflow can also flow through the heat dissipation hole 107 to the drive component 35 to dissipate heat from the drive component 35. That is, the suction component 60 can simultaneously dissipate heat from both the control component 71 and the drive component 35. This prevents the control component 71 or the drive component 35 from overheating and being damaged due to heat accumulation, ensuring the stability and reliability of the cleaning robot 100. On the other hand, there is no need to provide additional heat dissipation devices for the control component 71 or the drive component 35, thereby reducing production costs, reducing the number of parts in the cleaning robot 100, and simplifying the structural design of the cleaning robot 100.

[0055] The cleaning robot 100 will be described in detail below with reference to the accompanying drawings.

[0056] Referring to Figures 2 to 4, in some embodiments, the first air duct 106 includes an inlet air duct 1061 and an outlet air duct 1063. The inlet air duct 1061 communicates with the air inlet of the suction member 60 and is located on the front side of the suction member 60, that is, the inlet air duct 1061 is located in the front region of the suction member 60. The outlet air duct 1063 communicates with the air outlet of the suction member 60 and is located on the rear side of the suction member 60, that is, the outlet air duct 1063 is located in the rear region of the suction member 60. The heat dissipation hole 107 communicates with the outlet air duct 1063, at least a portion of the drive member 35 corresponds to the heat dissipation hole 107, and at least a portion of the heat dissipation member 73 is disposed in the inlet air duct 1061.

[0057] For example, at least a portion of the drive member 35 corresponds to the heat dissipation hole 107, including but not limited to the following situations:

[0058] The heat dissipation hole 107 is directly opposite the overall structure of the drive component 35. In this way, when the suction air flows through the heat dissipation hole 107 to the drive component 35, the suction air can come into contact with most of the structure of the drive component 35, thereby achieving uniform heat dissipation of the drive component 35 and improving the heat dissipation effect.

[0059] The heat dissipation hole 107 is directly opposite to a part of the structure of the drive component 35. For example, the main heat source of the drive component 35 (when the drive component 35 is a motor, it may be the motor winding, etc.) is directly opposite to the heat dissipation hole 107. This allows the suction airflow to specifically dissipate heat from the drive component 35 and improve heat dissipation efficiency.

[0060] The heat dissipation hole 107 corresponds to the side of the drive member 35 (for example, in the height direction Z of the body 10, the top or bottom of the drive member 35, or in the front-back direction or left-right direction Y of the body 10, one end or one side wall of the drive member 35). When the suction airflow flows to the drive member 35 through the heat dissipation hole 107, the suction airflow can carry away the heat dissipated around the drive member 35, thereby achieving heat dissipation of the drive member 35.

[0061] The drive unit 35 may include a heat transfer section, which corresponds to the heat dissipation hole 107. When the suction airflow flows to the heat transfer section through the heat dissipation hole 107, the suction airflow can carry away the heat on the heat transfer section, thereby achieving heat dissipation for the drive unit 35. The provision of the heat transfer section allows the drive unit 35 to be adapted to the structural layout of the cleaning robot 100, facilitating the compact arrangement of other components. The heat transfer section may be made of materials with good thermal conductivity, such as aluminum, copper, aluminum nitride, and silicon carbide.

[0062] Therefore, the heat sink 73 is located at the air inlet duct 1061, while the heat dissipation hole 107 is located at the air outlet duct 1063. Thus, compared to the case where both the heat sink 73 and the heat dissipation hole 107 are located at the air inlet duct 1061 or both at the air outlet duct 1063, the heat sink 73 and the heat dissipation hole 107 in this disclosure are far apart. The heat from the airflow brought in by the heat sink 73 will not flow directly to the heat dissipation hole 73, thereby preventing the suction airflow from conducting too much heat from the heat sink 73 to the drive component 35 through the heat dissipation hole 107, and thus ensuring the heat dissipation effect of the suction airflow on the drive component 35.

[0063] Furthermore, in some embodiments, the body 10 is provided with an air vent 19, which communicates with the air outlet duct 1063, so that the suction airflow can flow out to the outside through the air vent 19 to dissipate the carried heat to the external environment. Exemplarily, the air vent 19 is located on the side wall between the left and rear sides of the body 10. In some embodiments of this disclosure, the air vent 19 includes at least one. In one example, the air vent 19 includes one, in which case a filter is provided at the air vent 19, thereby ensuring the flow of suction airflow while preventing external impurities from entering the first air duct 106 through the air vent 19 and causing damage to the suction component 60 or other structures, ensuring the stability and reliability of the suction component 60's operation. In another example, the air vent 19 includes multiple air vents, which are arranged at intervals and jointly used to allow the suction airflow to flow out to the outside.

[0064] Referring to Figure 5, in some embodiments, a sealing element 77 is provided between the heat sink 73 and the air inlet duct 1061. The sealing element 77 is used to seal the gap between the heat sink 73 and the air inlet duct 1061. It should be noted that in some embodiments, the sealing element 77 includes, but is not limited to, rubber, silicone, or foam.

[0065] The sealing element 77 prevents the suction airflow from flowing out of the first air duct 106 through the gap between the heat sink 73 and the air inlet duct 1061, thereby ensuring the suction force of the suction element 60 on the dirt swept by the roller brush module 41 and ensuring the cleaning effect of the cleaning robot 100 on the surface to be cleaned.

[0066] Please refer to Figures 2, 3, and 5, and in conjunction with Figures 6 and 7. In some embodiments, the heat sink 73 includes a heat sink body 731 and a shielding portion 733 connected to the heat sink body 731. The shielding portion 733 extends protruding from the heat sink body 731 toward the main control board 711 and abuts against the main control board 711. The chip 713 is located within the shielding space 710 formed by the heat sink body 731, the shielding portion 733, and the main control board 711. A shielding member 75 is provided on the outer peripheral wall of the shielding portion 733. The shielding member 75 is used to prevent electromagnetic radiation from entering or leaving the shielding space 710.

[0067] Specifically, in some embodiments, the heat sink 731, the shielding part 733, and the main control board 711 can together form a closed shielding space 710, with the chip 713 located within the shielding space 710. Thus, the shielding space 710 protects the chip 713, reducing the possibility of damage. Furthermore, the shielding element 75 enables the shielding space 710 to have electromagnetic shielding effects, blocking electromagnetic radiation from entering and exiting the shielding space 710, protecting components such as the chip 713 from electromagnetic interference, and improving the stability and reliability of the control component 71. It should be noted that in some embodiments, the shielding element 75 can be conductive cloth, etc. Conductive cloth is a material based on fiber cloth (such as cotton, polyester, etc.) that has undergone special treatment to make its surface conductive. Of course, in other embodiments, the shielding element 75 can also be any other structure with electromagnetic shielding function; this disclosure does not impose any limitations.

[0068] It is understood that in this disclosure, there is no need to set up an additional shielding device 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 production costs.

[0069] In some embodiments of this disclosure, a heat-conducting component may be provided between the chip 713 and the heat sink 731. The heat-conducting component can improve the heat conduction efficiency between the chip 713 and the heat sink 731, thereby improving the heat dissipation effect. It should be noted that in some embodiments, the heat-conducting component may be a component with good thermal conductivity, such as thermal grease, and this disclosure does not impose any limitations.

[0070] Referring to Figures 6 and 7, in some embodiments, the heat sink 73 further includes a support portion 735 connected to the heat sink body 731. The support portion 735 protrudes from the heat sink body 731 toward the main control board 711 and is connected to the main control board 711. The support portion 735 and the main control board 711 can be joined together by welding or bolting, thus achieving the connection between the heat sink 73 and the main control board 711. In some embodiments of this disclosure, at least two support portions 735 may be included, spaced apart from each other on the heat sink body 731, thereby improving the stability of the connection between the heat sink 73 and the main control board 711.

[0071] And / or, referring to Figure 7, in some embodiments, the heat sink 73 further includes a heat dissipation portion 737 connected to the heat sink body 731. The heat dissipation portion 737 is disposed in the air inlet duct 1061 and extends protrudingly from the heat sink body 731 toward the air inlet duct 1061. The heat dissipation portion 737 increases the contact area between the heat sink 73 and the suction airflow, thereby improving heat dissipation efficiency and enhancing the heat dissipation effect of the heat sink 73 on the control component 71. It is understood that in some embodiments, multiple heat dissipation portions 737 are included, and the multiple heat dissipation portions 737 are spaced apart on the heat sink body 731.

[0072] Referring to Figures 1 to 3, in some embodiments, the air inlet duct 1061 is disposed between the left side 103 and the front side 101 of the body 10, that is, the air inlet duct 1061 is disposed in the area between the left and front sides of the body 10. This ensures that the air inlet duct 1061 can connect the dirt collection cavity 47 and the air inlet of the suction component 60, ensuring that the suction component 60 can suck the dirt cleaned by the roller brush module 41 into the dirt collection cavity 47. In addition, compared to the air inlet duct 1061 being disposed between the right side 104 and the front side 101 of the body 10, the arrangement of the air inlet duct 1061 in this disclosure can shorten the flow path of the suction airflow, thereby improving the suction efficiency of the suction component 60 and ensuring the cleaning effect of the cleaning robot 100.

[0073] In some embodiments, the exhaust duct 1063 is located between the left side 103 and the rear side 102 of the body 10, that is, in the area between the left and rear sides of the body 10. This ensures that the exhaust duct 1063 can connect the air outlet of the suction component 60 to the outside atmosphere, guaranteeing the normal operation of the suction component 60. Furthermore, compared to the exhaust duct 1063 being located between the right side 104 and the rear side 102 of the body 10, the arrangement of the inlet duct 1061 in this disclosure reduces the flow path of the suction airflow, thereby improving the suction efficiency of the suction component 60 and ensuring the cleaning effect of the cleaning robot 100.

[0074] In some embodiments, the housing 10 includes a middle frame 11 and a first housing 13. At least a portion of the cleaning module 30, the suction component 60, the control module 70, and the heat dissipation vents 107 are disposed on the middle frame 11. The first housing 13 is connected to the middle frame 11 and together they form a first air duct 106. Exemplarily, the first housing 13 covers the middle frame 11 so that the suction airflow flows within the space between the first housing 13 and the middle frame 11.

[0075] Compared to the design without a first housing 13, the first air duct 106 can be formed by the top cover 17 and the middle frame 11 of the cleaning robot, or by some housing structures located between the middle frame 11 and the top cover 17 and the middle frame 11. The first air duct 106 formed in this way is a relatively diffuse space without a fixed shape. The flow path of the suction airflow flowing in it is also relatively diffuse and has no fixed direction. It is also easy to leak from the gaps in it, which is not conducive to the heat dissipation function of the suction airflow. The first housing 13 allows the suction airflow generated when the suction component 60 is working to flow along a predetermined path, which makes it easier to control the direction of the suction airflow and prevent it from spreading to the surroundings. This enables the suction airflow to effectively dissipate heat from the control component 71 and the drive component 35, extends the service life of the control component 71 and the drive component 35, and ensures the normal operation of the cleaning robot 100.

[0076] In some embodiments of this disclosure, a sealing member may be provided between the first housing 13 and the middle frame 11. The sealing member can seal the gap between the first housing 13 and the middle frame 11, so that the first housing 13 and the middle frame 11 can jointly form a closed first air duct 106, preventing leakage of suction airflow. This ensures the suction function of the suction component 60 in removing dirt and improves the cleaning effect of the cleaning robot 100. On the other hand, it prevents noise caused by leakage of suction airflow, improving the user experience. It should be noted that the first air duct 106 in this disclosure can be an irregular shape as shown in Figure 3, which can adapt to the structural layout of the cleaning robot 100 and facilitate the compact arrangement of other components.

[0077] For example, the middle frame 11 may be provided with a groove, which is recessed from the top of the middle frame 11 (the side of the middle frame 11 opposite to the surface to be cleaned when the cleaning robot 100 is supported on the surface to be cleaned) toward the surface to be cleaned. The first housing 13 is covered at the opening of the groove and together with the middle frame 11 forms the first air duct 106. The first housing 13 can have a decorative effect on the body 10, reduce visual defects of the body 10, and improve the aesthetics of the body 10.

[0078] In some embodiments, the first housing 13 may be an integral structure, connected to the middle frame 11, and together forming the first air duct 106. In other embodiments, the first housing 13 may be a split structure; for example, the first housing 13 may include a first sub-shell and a second sub-shell. The first sub-shell is connected to the middle frame 11 and together forms the air inlet duct 1061, and the second sub-shell is connected to the middle frame 11 and together forms the air outlet duct 1063.

[0079] In some embodiments, the middle frame 11 and the first housing 13 can be an integral structure, that is, the middle frame 11 and the first housing 13 are an integral structure manufactured by an integral molding process. This can improve the bonding strength between the middle frame 11 and the first housing 13, ensure the sealing of the first air duct 106, prevent the middle frame 11 and the first housing 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 housing 13 can be separate structures, that is, the middle frame 11 and the first housing 13 are two different structures. This can facilitate the assembly of structures such as the suction component 60 on the middle frame 11 and improve assembly efficiency. The middle frame 11 and the first housing 13 can be connected together by a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​or bolt connection; non-detachable connection methods include, but are not limited to, adhesive or welding.

[0080] Please refer to Figures 1 and 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. A radar 25 is provided in the mounting groove 105. The detection signal of the radar 25 is emitted through the opening of the mounting groove 105. The radar 25 is used to detect the surrounding environment of the cleaning robot 100.

[0081] Specifically, in some embodiments, the mounting groove 105 may be a recess formed by the side wall of the rear side 102 of the body 10 inwards into 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 or assembly process errors.

[0082] In some embodiments of this disclosure, the edge of the mounting groove 105 is rounded, which on the one hand reduces scratches to the user when installing the radar 25 or other structural components, and facilitates the assembly of the radar 25 and other structural components in the mounting groove 105; on the other hand, it reduces visual defects at the opening of the mounting groove 105 and improves the aesthetics of the cleaning robot 100.

[0083] In some embodiments of this disclosure, the opening angle of the mounting slot 105 is greater than the field of view of the radar 25. This avoids the detection range of the radar 25 being limited due to an excessively small opening angle of the mounting slot 105, thereby reducing the possibility of blind spots in the cleaning robot 100 and improving the stability and reliability of its operation. Furthermore, it allows for the effective utilization of the radar 25, reducing resource waste. It should be noted that the radar 25 in this embodiment may be a radar without a 360° field of view.

[0084] In some embodiments of this disclosure, the opening angle of the mounting groove 105 is less than 240°. This ensures the detection range of the cleaning robot 100 on the rear side 102 of the body 10 while preventing the mounting groove 105 from being too large, which would result in insufficient structural strength of the body 10, reducing the possibility of deformation and damage to the body 10, and extending the service life of the body 10. It should be noted that the radar 25 in this embodiment can be a radar without a 360° field of view or a radar with a 360° field of view.

[0085] Radar 25 is a component in the cleaning robot 100 used to acquire information about the surrounding environment of the rear side 102 of the robot body 10. Radar 25 includes, but is not limited to, lidar, pulse radar, and continuous wave radar. Compared to radar 25 being located on the top of the cleaning robot 100 and protruding from the robot body 100, the arrangement of radar 25 in this disclosure does not occupy space in the height Z direction of the cleaning robot 100. This reduces the height of the cleaning robot 100, allowing it to enter small spaces such as under beds or sofas for cleaning, improving its applicability and effectively meeting user needs.

[0086] Furthermore, since the cleaning movement of the cleaning robot 100 typically includes forward movement and rotation, when the radar 25 is placed on the rear side 102 of the body 10, the cleaning robot 100 will generally not encounter obstacles colliding with the radar 25 during the cleaning process. This eliminates the need for a protective mechanism for the radar 25, thereby reducing production costs, enhancing the industry competitiveness of the cleaning robot 100, and also reducing the space occupied by the body 10, facilitating the size design of other structural components of the cleaning robot 100. Moreover, compared to the radar 25 being located on the front side 101 or the right side 104 of the body 10, when the radar 25 is placed on the rear side 102 of the body 10, there is no blind spot for detection on the rear side 102, effectively reducing the possibility of collisions when the cleaning robot 100 moves backward.

[0087] For example, when the radar 25 is located on the top of the body 10, when the cleaning robot 100 needs to enter the base station 300 (shown in FIG. 8) for maintenance, the cleaning robot 100 can enter the base station 300 in a backward posture. The cleaning robot 100 needs to rely on an infrared sensor to locate itself entering and exiting the base station 300. That is, the cleaning robot 100 is equipped with an infrared sensor, and the base station 300 is equipped with reflective stickers or other structural components that can cooperate with the infrared sensor, which leads to higher costs. However, in some embodiments of this disclosure, the radar 25 is located on the rear side 102 of the body 10. Thus, when the cleaning robot 100 needs to enter the base station 300, it can directly use the radar 25 to locate itself entering and exiting the base station 300. Compared to adding an infrared sensor, this is less costly and helps improve industry competitiveness.

[0088] Referring to Figures 3 and 4, in some embodiments, the fuselage 10 is also provided with a second air duct 108. The second air duct 108 is connected to the mounting groove 105 and the heat dissipation hole 107. When the suction component 60 is working and generates suction airflow, the suction airflow flows through the heat dissipation hole 107 and the second air duct 108 to the mounting groove 105 to dissipate heat from the radar 25.

[0089] Specifically, in some embodiments, the heat dissipation hole 107 is connected to the air outlet duct 1063. When the suction component 60 is working and generates a suction airflow in the first air duct 106, the suction airflow can not only dissipate heat from the control component 71 and the drive component 35, but also flow through the heat dissipation hole 107 and the second air duct 108 to the mounting groove 105 to dissipate heat from the radar 25 in the mounting groove 105. This prevents the heat generated by the radar 25 from accumulating and causing overheating damage, and prevents the heat from the radar 25 from adversely affecting other structural components of the cleaning robot 100, thereby extending the service life of the radar 25 and improving the stability and reliability of the radar 25's operation. In addition, using the suction airflow generated by the suction component 60 to dissipate heat from the radar 25 is a relatively simple heat dissipation method, which can make full use of the suction function of the suction component 60 and achieve efficient resource utilization. There is no need to set up a separate heat dissipation device to dissipate heat from the radar 25. This can reduce production costs while reducing the number of parts in the cleaning robot 100 and simplifying the structural design of the cleaning robot 100.

[0090] In some embodiments, the housing 10 includes a middle frame 11 and a second housing 15. At least a portion of the cleaning module 30, the suction component 60, the control module 70, and the heat dissipation vents 107 are disposed on the middle frame 11. The second housing 15 is connected to the middle frame 11 and together they form a second air duct 108. Exemplarily, the second housing 15 covers the middle frame 11 so that the suction airflow flows within the space between the second housing 15 and the middle frame 11.

[0091] Compared to the design without a second housing 15, the second air duct 108 can be formed by the top cover 17 and the middle frame 11 of the cleaning robot, or by some housing structures located between the middle frame 11 and the top cover 17 and the middle frame 11. The resulting second air duct 108 is a relatively diffuse space without a fixed shape. The flow path of the suction airflow flowing in it is also relatively diffuse and has no fixed direction. It is also easy to leak from the gaps in it, which is not conducive to the heat dissipation function of the suction airflow. The second housing 15 allows the suction airflow generated when the suction component 60 is working to flow along a preset path, thereby achieving effective heat dissipation of the radar 25 by the suction airflow, extending the service life of the radar 25, and ensuring the normal operation of the cleaning robot 100.

[0092] In some embodiments of this disclosure, a sealing element may be provided between the second housing 15 and the middle frame 11. The sealing element can seal the gap between the second housing 15 and the middle frame 11 so that the second housing 15 and the middle frame 11 can jointly form a closed second air duct 108 to prevent leakage of the suction airflow. This can prevent noise caused by the leakage of the suction airflow and improve the user experience.

[0093] In some embodiments, the middle frame 11 and the second housing 15 can be an integral structure, that is, the middle frame 11 and the second housing 15 are a single structure manufactured using an integral molding process. This can improve the bonding strength between the middle frame 11 and the second housing 15, prevent the middle frame 11 and the second housing 15 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 second housing 15 can be separate structures, that is, the middle frame 11 and the second housing 15 are two different structures. This facilitates the assembly of structures such as the suction component 60 onto the middle frame 11, improving assembly efficiency. The middle frame 11 and the second housing 15 can be joined together using a detachable connection method or a non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​or bolted connections; non-detachable connection methods include, but are not limited to, adhesive or welding.

[0094] Please refer to Figures 1, 2 and 8. This disclosure also provides a cleaning system 1000, including a cleaning robot 100 as described in any of the above embodiments and a base station 300 used in conjunction with the cleaning robot 100. The base station 300 includes a docking position 301 for accommodating the cleaning robot 100.

[0095] The base station 300 is a device capable of maintaining the cleaning robot 100. It is understood that, in some embodiments, when the cleaning robot 100 is located at its docking position 301 on the base station 300, the base station 300 can perform maintenance on the cleaning robot 100, including but not limited to charging, dust collection, cleaning of the cleaning components, replenishing clean water, and pumping out wastewater. Specifically, the cleaning robot 100 can perform at least one of the following within the base station 300: 1. Charging the cleaning robot 100; 2. Recycling debris (e.g., debris from the cleaning robot 100's dust box or wastewater tank) into its dust collection container; 3. Cleaning the cleaning components 33 of the cleaning robot 100 within the base station 300 (e.g., washing the mop, cleaning the roller brush, washing the roller); 4. Replenishing the cleaning robot 100's clean water tank with clean water; 5. Recycling dirt from the cleaning robot 100's wastewater tank into its wastewater container and discharging it externally. The maintenance types described above are merely illustrative and are not intended to limit this disclosure.

[0096] Since the cleaning system 1000 in this embodiment includes the cleaning robot 100, it is understood that the cleaning system 1000 includes at least the same beneficial effects as the cleaning robot 100. Therefore, the beneficial effects of the cleaning system 1000 can be referred to the beneficial effects of the cleaning robot 100 above, and will not be repeated here.

[0097] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. Furthermore, other implementation methods can be derived from the above embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0098] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the scope of protection of this disclosure. Therefore, the scope of protection of this patent should be determined by the appended claims.
