Description

Technical Field

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

[0002] A cleaning robot is a device used to automatically clean carpets or floors awaiting cleaning, typically used in home cleaning, large venue cleaning, and other similar applications. Related technologies include a cleaning robot comprising a fan and a cleaning device, which cleans the surface to be cleaned. Generally, a cleaning robot uses a fan to draw air from the cleaning device, creating a negative pressure inside. This pressure difference then forces debris from the surface to be cleaned into the cleaning device. However, current cleaning devices often have poor airtightness, making it difficult to create negative pressure inside, thus affecting the cleaning effectiveness. Utility Model Content

[0003] This disclosure provides a cleaning device, a cleaning robot, and a cleaning system to solve at least one of the aforementioned technical problems.

[0004] In a first aspect, this disclosure provides a cleaning device for a cleaning robot, which, when performing a cleaning task, cleans debris from a surface to be cleaned using the cleaning device. The cleaning device includes a roller brush housing, a shielding assembly, and a first seal. The roller brush housing is disposed on the body of the cleaning robot and includes a roller brush cavity shell and a cover. The roller brush cavity shell has a receiving cavity and a suction port communicating with the receiving cavity. The suction port allows debris from the surface to be cleaned to enter the receiving cavity. The cover covers the suction port. The shielding assembly is movably connected to the roller brush housing and can move relative to the roller brush housing to change the opening size of the suction port. At least a portion of the first seal is flexible. The first seal is connected to the shielding assembly, and for at least a portion of a time after the shielding assembly reduces the opening size of the suction port, the first seal seals the gap between the shielding assembly and the cover.

The roller brush housing is disposed on the body of the cleaning robot and includes a roller brush cavity shell and a cover. The roller brush cavity shell has a receiving cavity and a suction port communicating with the receiving cavity. The suction port is used to allow debris on the surface to be cleaned to enter the receiving cavity. The cover is placed over the suction port. The shielding assembly is movably connected to the roller brush housing and can move relative to the roller brush housing to change the opening size of the suction port. At least a portion of the first seal is flexible. The first seal is connected to the shielding assembly, and for at least a portion of a time after the shielding assembly reduces the opening size of the suction port, the first seal seals the gap between the shielding assembly and the cover.

[0006] Thirdly, this disclosure provides a cleaning system comprising 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 and a cleaning device. The cleaning device is disposed on the body and is used to clean the surface to be cleaned. The cleaning device includes a roller brush housing, a shielding assembly, and a first seal. The roller brush housing is disposed on the body of the cleaning robot and includes a roller brush cavity shell and a cover. The roller brush cavity shell has a receiving cavity and a suction port communicating with the receiving cavity. The suction port is used to allow debris on the surface to be cleaned to enter the receiving cavity. The cover is disposed on the suction port. The shielding assembly is movably connected to the roller brush housing and can move relative to the roller brush housing to change the opening size of the suction port.

[0027] The embodiments of this disclosure will be further described below with reference to the accompanying drawings. The same or similar reference numerals in the drawings denote the same or similar elements or elements having the same or similar functions throughout. Furthermore, the embodiments of this disclosure described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this disclosure, and should not be construed as limiting this disclosure.

[0028] A cleaning robot is a device used to automatically clean surfaces such as carpets, tabletops, walls, glass, doors, or floors. It is commonly used in home cleaning and large-scale venue cleaning. Related technologies typically include a fan and a cleaning device, which cleans the surface to be cleaned. Generally, a cleaning robot uses a fan to draw air from the cleaning device, creating a negative pressure inside. This pressure difference then draws debris from the surface into the cleaning device. However, current cleaning devices often have poor airtightness, making it difficult to create negative pressure inside, thus affecting the cleaning efficiency. To address these issues, please refer to [link to relevant documentation]. Figure 1 This disclosure provides a cleaning device 100, a cleaning robot 1000, and a cleaning system 5000.

[0029] Please see Figure 1 This disclosure provides a cleaning system 5000, which includes a cleaning robot 1000 and a base station 3000. The base station 3000 is used in conjunction with the cleaning robot 1000 and includes a docking position 3100 for accommodating the cleaning robot 1000.

[0030] Specifically, the cleaning robot 1000 is an intelligent device capable of performing functions such as sweeping, vacuuming, and mopping. The cleaning robot 1000 includes, but is not limited to, sweeping robots, mopping robots, combined sweeping and mopping robots, intelligent robots, and mobile robots. It is understood that, in some embodiments, when the cleaning robot 1000 is located at its docking position 3100, the base station 3000 can perform maintenance on the cleaning robot 1000, including but not limited to charging, dust collection, cleaning of washing components, replenishment of clean water, and pumping of wastewater. This can be understood as follows: the cleaning robot 1000 can perform at least one of the following within the base station 3000: 1. The base station 3000 charges the cleaning robot 1000; 2. The base station 3000 collects the debris (e.g., debris from the cleaning robot's dust box or wastewater tank) from the cleaning robot 1000 into its dust collection container (e.g., the base station's dust bag); 3. The base station 3000 cleans the cleaning components of the cleaning robot 1000 within the base station 3000 (e.g., washes the mop, cleans the roller brush, washes the roller); 4. The base station 3000 replenishes the cleaning robot 1000's clean water tank with clean water; 5. The base station 3000 collects the dirt from the cleaning robot 1000's wastewater tank into its wastewater container (e.g., the base station's wastewater tank) and discharges it to the outside. The above maintenance types are merely illustrative descriptions and are not intended to limit this disclosure.

[0031] Since the cleaning system 5000 in this embodiment includes the cleaning robot 1000, it is understood that the cleaning system 5000 includes at least the same beneficial effects as the cleaning robot 1000. Therefore, for the beneficial effects of the cleaning system 5000, please refer to the beneficial effects of the cleaning robot 1000 described below.

[0032] Please see Figure 1 and Figure 2 This disclosure provides a cleaning robot 1000, which includes a body 300 and a cleaning device 100. The cleaning device 100 is disposed on the body 300 and is used to clean the surface to be cleaned. When performing a cleaning task, the cleaning robot 1000 uses the cleaning device 100 to sweep away debris from the surface to be cleaned.

[0033] Specifically, the body 300 is the structure of the cleaning robot 1000 used to mount and protect the cleaning device 100 and other devices of the cleaning robot 1000. The body 300 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. In one example, the body 300 can be made of both metallic and non-metallic materials, thereby increasing the structural strength of the body 300, preventing collision damage during the operation of the cleaning robot 1000, and improving the stability and reliability of the cleaning robot 1000. In another example, the body 300 can be made of non-metallic materials, for example, plastic, thereby making the body 300 lighter and contributing to the portability of the cleaning robot 1000.

[0034] The cleaning device 100 is a component of the cleaning robot 1000 that enables the robot to perform mopping or sweeping functions. That is, the cleaning device 100 can mop and / or sweep the surface to be cleaned. Specifically, 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 other objects that need cleaning, such as walls, beds, or windows.

[0035] Since the cleaning robot 1000 in this embodiment includes a cleaning device 100, it is understood that the cleaning robot 1000 has at least the same beneficial effects as the cleaning device 100. Therefore, for the beneficial effects of the cleaning robot 1000, please refer to the beneficial effects of the cleaning device 100 described below.

[0036] Please see Figure 4 This disclosure provides a cleaning device 100 for a cleaning robot 1000. The cleaning device 100 includes a roller brush housing 10, a shielding assembly 20, and a first seal 30. The roller brush housing 10 is disposed on the body 300 of the cleaning robot 1000 and includes a roller brush cavity housing 11 and a cover 13. The roller brush cavity housing 11 has a receiving cavity 111 and a suction port 113 communicating with the receiving cavity 111. The suction port 113 is used to allow debris from the surface to be cleaned to enter the receiving cavity 111. The cover 13 covers the suction port 113. The shielding assembly 20 is movably connected to the roller brush housing 10 and can move relative to the roller brush housing 10 to change the opening size of the suction port 113. At least a portion of the first seal 30 is flexible. The first seal 30 is connected to the shielding assembly 20 and seals the gap between the shielding assembly 20 and the cover 13 for at least a portion of the time period after the shielding assembly 20 reduces the opening size of the suction port 113.

[0037] The material of the roller brush housing 10 can be metallic and / or non-metallic. 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. The cover 13 is detachably connected to the roller brush chamber housing 11, and the detachable connection method includes, but is not limited to, snap-fit ​​connections or bolt connections; or, the cover 13 is non-detachably connected to the roller brush chamber housing 11, and the non-detachable connection method includes, but is not limited to, bonding or welding. It should be noted that the materials of the roller brush chamber housing 11 and the cover 13 can be the same or different. For example, both the roller brush chamber housing 11 and the cover 13 can be made of plastic; or, one of the roller brush chamber housing 11 and the cover 13 can be made of metal, and the other can be made of plastic.

[0038] In some embodiments of this disclosure, when the cleaning robot 1000 sweeps the garbage on the surface to be cleaned by the cleaning device 100, the suction port 113 is opposite to the surface to be cleaned. In the forward direction X of the cleaning robot 1000, the end of the roller brush housing 10 near the front end of the body 300 is spaced apart from (not in contact with) the surface to be cleaned, and the end of the roller brush housing 10 near the rear end of the body 300 is in contact with the surface to be cleaned. That is, in the forward direction X of the cleaning robot 1000, the end of the suction port 113 near the front end of the body 300 is not in contact with the surface to be cleaned, and the end of the suction port 113 near the rear end of the body 300 is in contact with the surface to be cleaned. In this way, as much garbage as possible can be sucked into the roller brush housing 10 through the suction port 113. Compared with the case where the side of the suction port 113 near the rear end of the body 300 is not in contact with the surface to be cleaned, the cleaning device 100 in this embodiment is less likely to miss garbage, thereby improving the cleaning effect of the cleaning device 100.

[0039] It should be noted that the orientations described in the embodiments of this disclosure are defined with the cleaning robot 1000 mounted on the surface to be cleaned. "Front end" and "rear end" are relative to the forward direction X of the cleaning robot 1000. When the cleaning robot 1000 moves forward along the forward direction X, the front end of the body 300 closest to the forward direction X is the front end of the body 300, and the rear end of the body 300 closest to the forward direction X is the rear end of the body 300.

[0040] Understandably, the size of the inlet 113 affects the suction force of the receiving cavity 111. Specifically, the larger the opening of the inlet 113, the smaller the suction force of the receiving cavity 111, the lower the cleaning efficiency of the cleaning device 100, and the more difficult it is for debris to be sucked into the receiving cavity 111; conversely, the smaller the opening of the inlet 113, the greater the suction force of the receiving cavity 111, the higher the cleaning efficiency of the cleaning device 100, and the easier it is for debris to be sucked into the receiving cavity 111. In other words, when cleaning debris on the same surface to be cleaned, the larger the opening of the inlet 11, the greater the suction force required. Therefore, in some embodiments of this disclosure, the shielding component 20 can move relative to the roller brush housing 10 to change the opening size of the suction port 113, thereby adjusting the suction force of the receiving cavity 111. Thus, the cleaning device 100 can adjust the opening size of the suction port 113 according to the different adaptability of the surface to be cleaned, ensuring that the garbage on different surfaces to be cleaned can be sucked into the receiving cavity 111, thereby improving the applicability of the cleaning device 100 and the cleaning robot 1000 and ensuring the cleaning effect of the cleaning device 100 and the cleaning robot 1000.

[0041] For example, when the surface to be cleaned is the target area, i.e., the area requiring deep cleaning (e.g., carpet area, floor mat area, foot mat area, yoga mat area, rubber mat area, straw or bamboo mat area, heavily soiled area, user-defined area, etc.), the shielding component 20 can move relative to the roller brush housing 10 to reduce the opening size of the suction port 113. When the surface to be cleaned is a non-target area, i.e., the area not requiring deep cleaning or only requiring normal cleaning, or the area to be cleaned other than the target area (e.g., an area without carpet, an open floor, etc.), the shielding component 20 can move relative to the roller brush housing 10 to increase the opening size of the suction port 113. Further, in some embodiments, the cleaning device 100 also includes a drive component 80, which is connected to the shielding component 20. When the drive component 80 is operating stably, the driving force of the drive component 80 can be transmitted to the shielding component 20 to drive the shielding component 20 to move relative to the roller brush housing 10. The drive assembly 80 can be located in the brush housing 10 or the body 300.

[0042] If a large gap exists between the shielding component 20 and the cover 13, the receiving cavity 111 will still communicate with the outside through the gap between the shielding component 20 and the cover 13 for at least a portion of the time after the shielding component 20 reduces the opening size of the suction inlet 113. This will make it difficult for the receiving cavity 111 to achieve a high vacuum, affecting the cleaning effect of the cleaning device 100. Therefore, in some embodiments of this disclosure, the first sealing member 30 can ensure the sealing effect of the receiving cavity 111 after the shielding component 20 reduces the opening size of the suction inlet 113, enabling the receiving cavity 111 to achieve a high vacuum, thereby improving the cleaning effect of the cleaning device 100. In addition, it can also prevent dust, debris, moisture, etc. from entering the interior through the gaps, affecting the jamming of the components during operation, and affecting the service life of the components. It should be noted that in some embodiments, the material of the first sealing member 30 includes, but is not limited to, rubber, silicone, and foam.

[0043] In some embodiments, one end of the first seal 30 is connected to the shielding assembly 20, and the other end of the first seal 30 is connected to the cover 13. Specifically, in one example, at least a portion of the first seal 30 is elastic, capable of elastic deformation (extension and contraction) when the first seal 30 is subjected to force. During the movement of the shielding assembly 20 relative to the brush housing 10, the first seal 30 can elastically deform, thus preventing the first seal 30 from interfering with the movement of the shielding assembly 20 relative to the brush housing 10; and ensuring that, for at least a portion of the time after the shielding assembly 20 reduces the opening size of the suction inlet 113, the first seal 30 can seal the gap between the shielding assembly 20 and the cover 13. In another example, the first seal 30 includes a pleated portion, which is a generally continuously bent curved surface structure capable of deformation under force. During the movement of the shielding component 20 relative to the roller brush housing 10, the pleats can deform. This can prevent the first seal 30 from interfering with the movement of the shielding component 20 relative to the roller brush housing 10. On the other hand, it can ensure that the first seal 30 can seal the gap between the shielding component 20 and the cover 13 for at least a part of the time after the shielding component 20 reduces the opening size of the suction port 113.

[0044] In other embodiments, one end of the first seal 30 is connected to the shielding assembly 20, while the other end is not connected to the cover 13. Specifically, for at least a portion of the time after the shielding assembly 20 reduces the opening size of the suction inlet 113, the other end of the first seal 30 can contact the cover 13, thereby sealing the gap between the shielding assembly 20 and the cover 13. Furthermore, compared to having one end of the first seal 30 connected to the shielding assembly 20 and the other end connected to the cover 13, the shielding assembly 20 is not pulled by the first seal 30 when moving relative to the brush housing 10. This ensures the stability and reliability of the movement of the shielding assembly 20 relative to the brush housing 10, and reduces the power consumption required for the cleaning device 100 to drive the shielding assembly 20 to move relative to the brush housing 10, thus increasing the battery life of the cleaning robot 1000.

[0045] In some embodiments, the cleaning device 100 further includes a roller brush 18 and a lifting assembly 90. The roller brush 18 is at least partially disposed within the roller brush housing 10 and is connected to the drive assembly 80. The shielding assembly 20 is connected to the drive assembly 80. The lifting assembly 90 is connected to the drive assembly 80 and the roller brush housing 10. The drive assembly 80 is used to drive the roller brush 18 to rotate to clean the surface to be cleaned, to drive the shielding assembly 20 to move to change the opening size of the suction inlet 113, and to drive the lifting assembly 90 to move the roller brush housing 10, thereby causing the roller brush 18 to rise and fall relative to the body 300.

[0046] For example, the roller brush 18 is disposed within the receiving cavity 111 and contacts the surface to be cleaned through the suction port 113. When the driving force generated by the drive assembly 80 is transmitted to the roller brush 18, the roller brush 18 rotates relative to the roller brush cavity housing 11 under the drive of the drive assembly 80. In this way, the roller brush 18 can sweep away the debris on the surface to be cleaned, and the debris can be sucked into the receiving cavity 111 through the suction port 113 under the action of the suction airflow, thereby achieving the cleaning of the surface to be cleaned. It should be noted that the opening size of the suction port 113 can be the size of the opening on the roller brush housing 10 for allowing debris to enter the receiving cavity 111 during the cleaning process of the cleaning device 100 sweeping the surface to be cleaned. For example, the opening size of the suction port 113 can be the height of the blocking member 21 and the surface to be cleaned in the direction perpendicular to the surface to be cleaned. That is, the greater the height of the blocking member 21 from the surface to be cleaned in the direction perpendicular to the surface to be cleaned, the larger the opening size of the corresponding suction port 113.

[0047] See Figure 2 and Figure 3The drive assembly 80 includes a drive member 81 and a transmission member 83. The transmission member 83 is connected to the output end of the drive member 81 and is used to transmit the driving force of the drive member 81 to the roller brush 18, the shielding assembly 20, or the lifting assembly 90. Specifically, in some embodiments, when the drive member 81 is operating stably, the drive member 81 can output driving force, and the driving force can be transmitted through the transmission member 83 to the roller brush 18, the shielding assembly 20, or the lifting assembly 90 to drive the roller brush 18, the shielding assembly 20, or the lifting assembly 90 to move. In some embodiments, when the output end of the drive member 81 rotates in a first rotation direction, the transmission member 83 transmits the driving force of the drive member 81 to the roller brush 18, which can drive the roller brush 18 to rotate to clean the surface to be cleaned. When the output end of the drive member 81 rotates in a second rotation direction, the transmission member 83 transmits the driving force of the drive member 81 to at least the shielding assembly 20 or the lifting assembly 90, and the first rotation direction and the second rotation direction are opposite. It should be noted that in some embodiments, when the driving member 81 is a motor, the output end of the driving member 81 is the output shaft of the driving member 81. For example, when the transmission member 83 cooperates with the blocking assembly 20, it drives the blocking assembly 20 towards... Figure 3 When the device moves in the A2 direction, the shielding assembly 20 reduces the opening size of the suction inlet 113 (the shielding member 21 moves towards the surface to be cleaned); this causes the shielding assembly 20 to move towards... Figure 3 When the device moves in the A1 direction, the shielding component 20 increases the opening size of the suction inlet 113 (the shielding component 21 moves away from the surface to be cleaned). For example, when the transmission component 83 cooperates with the lifting component 90 (the lifting component 90 moves towards...), Figure 3 When the roller brush housing 10 moves in the B2 direction, the bracket 340 of the machine body 300 applies a force (e.g., pressing the bracket 340 down toward the surface to be cleaned), causing the roller brush housing 10 to rotate around the rotating shaft 15 (the rotating arm 16 of the roller brush housing 10 is connected to the machine body 300 via the rotating shaft 15), thereby lifting the roller brush housing 10 upward, which in turn drives the roller brush 18 to rise; when the transmission component 83 is disengaged from the lifting component 90 (the lifting component 90 moves toward the B2 direction), the roller brush housing 10 rotates around the rotating shaft 15, causing the roller brush housing 10 to rotate upward, which in turn drives the roller brush 18 to rise; when the transmission component 83 is disengaged from the lifting component 90 (the lifting component 90 moves toward the B2 direction), the roller brush housing 10 rotates around the rotating shaft 15, causing the roller brush Figure 3 (Moves in the B1 direction), the roller brush housing 10 descends, causing the roller brush 18 to descend along with it.

[0048] For ease of explanation, the following embodiments will be described in the example where one end of the first sealing member 30 is connected to the shielding component 20 and the other end of the first sealing member 30 is not connected to the cover 13.

[0049] In the cleaning device 100 of this embodiment, for at least a portion of the time after the shielding component 20 reduces the opening size of the suction port 113, the first sealing member 30 seals the gap between the shielding component 20 and the cover 13. This ensures the sealing effect of the receiving cavity 111 after the shielding component 20 reduces the opening size of the suction port 113, improves the airtightness of the receiving cavity 111, and facilitates the receipt of the receiving cavity 111 to achieve a high vacuum, thereby improving the cleaning effect of the cleaning device 100.

[0050] The cleaning device 100 will be further explained below with reference to the accompanying drawings.

[0051] In some embodiments, the cleaning robot also includes a fan 40 (not shown in the figure, disposed inside the body), which communicates with the receiving cavity 111. It should be noted that in some embodiments, the fan 40 includes, but is not limited to, a centrifugal fan, an axial fan, a mixed (oblique) flow fan, and a crossflow fan.

[0052] Specifically, when the blower 40 is drawing air, it can remove air from the receiving cavity 111 to create a negative pressure state. At this time, there is a certain pressure difference between the receiving cavity 111 and the external atmospheric pressure, thereby giving the receiving cavity 111 a certain suction force to suck up the garbage on the surface to be cleaned. It can be understood that when the shielding component 20 moves relative to the roller brush housing 10 to reduce the opening size of the suction port 113, the receiving cavity 111 can more effectively achieve a high vacuum, thereby improving the cleaning effect of the cleaning device 100.

[0053] Further, see Figure 2 and Figure 3 In some embodiments, the roller brush housing 10 is further provided with a suction port 19, which communicates with the receiving cavity 111. The suction port 19 is used to allow the waste in the receiving cavity 111 to move out of the receiving cavity 111. The fan 40 is connected to the receiving cavity 111 through the suction port 19. Specifically, when waste enters the receiving cavity 111, the waste in the receiving cavity 111 can be moved out of the receiving cavity 111 through the suction port 19 under the suction action of the fan 40 and enter the waste collection container (e.g., dust box) of the cleaning robot 1000.

[0054] In some embodiments, when the fan 40 is drawing air, the first seal 30 swings toward the cover 13.

[0055] Specifically, in some embodiments, when the fan 40 is drawing air, a negative pressure state is formed in the receiving cavity 111 and a suction force is generated. At this time, the flexible part of the first sealing member 30 can swing towards the cover 13 under the action of negative pressure to seal the gap between the shielding component 20 and the cover 13. That is, the flexible part of the first sealing member 30 can deform under the action of negative pressure and contact the cover 13, thereby sealing the gap between the shielding component 20 and the cover 13. This can improve the airtightness of the receiving cavity 111 and ensure that the receiving cavity 111 can achieve a high vacuum when the fan 40 is drawing air. On the other hand, it can enable the first sealing member 30 to dynamically adjust its relative position with the cover 13 to adapt to the suction of the fan 40 and ensure that the first sealing member 30 can effectively fit the cover 13 to seal the gap between the shielding component 20 and the cover 13.

[0056] Furthermore, the first seal 30 swings toward the cover 13 to seal the gap between the shielding assembly 20 and the cover 13. Thus, compared to sealing the gap between the shielding assembly 20 and the cover 13 by using the interference fit between the first seal 30 and the shielding assembly 20 and the cover 13, the first seal 30 does not generate much resistance to the movement of the shielding assembly 20 relative to the roller brush housing 10. This reduces the power consumption required for the cleaning device 100 to drive the shielding assembly 20 to move relative to the roller brush housing 10, which helps to increase the battery life of the cleaning robot 1000. In addition, the friction between the first seal 30 and the shielding assembly 20 and / or the cover 13 is small, which reduces the possibility of the first seal 30 breaking and failing, and ensures the sealing effect of the first seal 30 on the gap between the shielding assembly 20 and the cover 13.

[0057] In some embodiments, the cover 13 includes a mating surface 131 facing the surface to be cleaned. The first seal 30 includes a connecting portion 31 and a swinging portion 33. The connecting portion 31 is connected to the shielding assembly 20. When the fan 40 draws air, the swinging portion 33 swings toward the mating surface 131 until it contacts the mating surface 131. Specifically, in some embodiments, at least a portion of the swinging portion 33 is flexible. When the fan 40 draws air, a negative pressure state is formed in the receiving cavity 111. At this time, the swinging portion 33 can swing toward the mating surface 131 under the action of negative pressure until it contacts the mating surface 131, thereby sealing the gap between the shielding assembly 20 and the cover 13.

[0058] In some embodiments, the connecting portion 31 and the swing portion 33 are an integral structure, that is, the connecting portion 31 and the swing portion 33 can be integrally molded into a single structure, thereby improving the bonding strength between the connecting portion 31 and the swing portion 33 and preventing cracking between the connecting portion 31 and the swing portion 33 during the cleaning process of the cleaning device 100, thus ensuring the effective sealing of the gap between the first sealing member 30 and the cover 13. In other embodiments, the connecting portion 31 and the swing portion 33 can be separate structures, that is, the connecting portion 31 and the swing portion 33 are two different structures. The connecting portion 31 and the swing portion 33 can be combined by a non-removable connection method or a detachable connection method, wherein the non-removable connection method includes, but is not limited to, bonding or welding; the detachable connection method includes, but is not limited to, snap-fit ​​connection or threaded connection.

[0059] In some embodiments, as the fan 40 increases its suction, the contact area between the swing part 33 and the mating surface 131 gradually increases and / or the contact tightness between the swing part 33 and the mating surface 131 gradually increases.

[0060] Specifically, when the suction of the blower 40 increases, the suction force of the receiving cavity 111 increases. In this case, since at least part of the swing part 33 is flexible, the swing part 33 can change shape under the action of the suction force, so that the contact area between the swing part 33 and the mating surface 131 gradually increases; and / or, the contact tightness between the swing part 33 and the mating surface 131 gradually increases. For example, the swing part 33 changes from partially contacting the mating surface 131 to completely contacting the mating surface 131, and the swing part 33 changes from having a gap with the mating surface 131 to having no gap with the mating surface 131. This allows the first seal 30 to more effectively seal the gap between the shielding assembly 20 and the cover 13, which is beneficial to achieving a high vacuum in the receiving cavity 111, thereby improving the cleaning effect of the cleaning device 100.

[0061] Please see Figures 3 to 4 In some embodiments, the shielding assembly 20 includes a shielding member 21, which is rotatably connected to the cover 13 and is rotatable relative to the cover 13 to a first shielding position. Figure 6 (as shown) and the second occlusion position ( Figure 5 The movement between the shielding member 21 and the second shielding member 21 is greater than the opening size of the suction port 113 when the shielding member 21 is in the first shielding position; the first sealing member 30 is connected to the shielding member 21, and when the shielding member 21 is in the second shielding position, the first sealing member 30 abuts against the mating surface 131.

[0062] Specifically, in some embodiments, when the driving force of the drive assembly 80 is transmitted to the shield 21, the shield 21 can rotate relative to the cover 13 to switch between a first shielding position and a second shielding position, and change the opening size of the suction port 113, thereby changing the suction force of the receiving cavity 111, so that the cleaning robot 1000 can be adapted to different working scenarios. The connecting portion 31 of the first seal 30 is connected to the shield 21, so that when the shield 21 is in the second shielding position, the swing portion 33 of the first seal 30 can abut against the mating surface 131, thereby sealing the gap between the shield 21 and the cover 13.

[0063] It should be noted that, in some embodiments, the cross section of the shield 21 cut by a plane perpendicular to the forward direction X of the cleaning robot 1000 is greater than or equal to the cross section of the suction port 113 cut by a plane perpendicular to the forward direction X of the cleaning robot 1000. Thus, during the process of the shield 21 switching from the first shielding position to the second shielding position, the shield 21 can effectively shield the suction port 113 to reduce the opening size of the suction port 113.

[0064] Optionally, the shielding member 21 can be made of an elastic material, including but not limited to rubber and silicone. Thus, during the cleaning process of the cleaning device 100 cleaning the surface to be cleaned, the shielding member 21 can undergo a certain elastic deformation to allow the waste to smoothly pass through the suction port 113 into the receiving cavity 111, thereby preventing the shielding member 21 from obstructing the waste and improving the cleaning effect. Furthermore, using an elastic material can prevent the shielding member 21 from rigidly colliding with harder waste, thus extending its service life and ensuring the normal operation of the shielding assembly 20. Of course, in other embodiments, the shielding member 21 can also be made of a non-elastic material.

[0065] Furthermore, please combine Figure 3 In some embodiments, the shielding component 20 may further include a connector 23, one end of which is connected to the drive component 80 and the other end of which is connected to the shielding component 21. When the driving force of the drive component 80 is transmitted to the connector 23, the connector 23 can move relative to the roller brush housing 10 in the rotation direction (A1 / A2) to drive the shielding component 21 to move relative to the cover 13. Specifically, the connector 23 moves in the A1 direction to drive the shielding component 21 to move away from the surface to be cleaned, and the connector 23 moves in the A2 direction to drive the shielding component 21 to move closer to the surface to be cleaned. This allows the shielding component 21 to switch between a first shielding position and a second shielding position to change the opening size of the suction port 113, thereby changing the suction force of the receiving cavity 111 and enabling the cleaning robot 1000 to be applicable to different working scenarios.

[0066] In some embodiments, the first seal 30 and the shield 21 are an integral structure, that is, the first seal 30 and the shield 21 can be integrally molded to form a single structure, thereby improving the bonding strength between the first seal 30 and the shield 21 and preventing the first seal 30 from falling off the shield 21 during the cleaning process of the cleaning device 100. In other embodiments, the first seal 30 and the shield 21 can be separate structures, that is, the first seal 30 and the shield 21 are two different structures. The first seal 30 and the shield 21 can be connected together using a non-detachable connection or a detachable connection.

[0067] Please see Figure 4 In some embodiments, the cover 13 further includes a ground surface 133, and the mating surface 131 is located at the front end of the cleaning robot 1000 in the forward direction X relative to the ground surface 133. At least a portion of the mating surface 131 is inclined relative to the ground surface 133. When the cleaning device 100 is cleaning the surface to be cleaned, the mating surface 131 does not contact the surface to be cleaned, while the ground surface 133 contacts the surface to be cleaned. This allows the end of the suction port 113 near the front end of the body 300 in the above embodiments to not contact the surface to be cleaned, while the end of the suction port 113 near the rear end of the body 300 contacts the surface to be cleaned. This ensures that the debris on the surface to be cleaned can enter the receiving cavity 111. Furthermore, compared to when the mating surface 131 contacts the surface to be cleaned when the cleaning device 100 is cleaning the surface, it reduces the amount of debris that the cleaning device 100 misses on the surface to be cleaned.

[0068] It should be noted that the "non-contact" described in this disclosure refers to the cleaning robot not contacting the surface to be cleaned when it is placed on a relatively flat surface. This excludes contact in other states, including but not limited to: contact between the cleaning robot and obstacles or the surface to be cleaned due to the robot's vertical movement when traversing obstacles; contact between the cleaning robot and the base station floor due to inclines or declines when entering or exiting base stations; contact caused by the robot's vertical movement when walking on uneven surfaces; contact between the cleaning robot and large or flying debris on the surface to be cleaned, or contact caused by unevenness in the surface itself, when performing cleaning tasks. For example, when the cleaning robot is stationary on a relatively flat surface to be cleaned, the mating surface does not contact the surface to be cleaned, while the grounding surface does (e.g., the mating surface is tilted relative to the grounding surface, the grounding surface rests on the surface to be cleaned, and the mating surface is suspended above the surface to be cleaned); as another example, when the cleaning robot is stationary in a relatively flat non-target area, the blocking component does not contact the non-target area (e.g., the blocking component is suspended above the non-target area); as yet another example, when the cleaning robot is stationary in a relatively flat target area, the blocking component contacts the target area (e.g., at least a portion of the blocking component contacts the target area).

[0069] Specifically, in some embodiments, when the cleaning robot 1000 is carried on the surface to be cleaned, the ground surface 133 is parallel to the surface to be cleaned, and the mating surface 131 is inclined relative to the ground surface 133. Furthermore, in the forward direction X of the cleaning robot 1000, the distance between the mating surface 131 and the surface to be cleaned gradually increases. Therefore, compared to when the mating surface 131 is parallel to the surface to be cleaned, when the fan 40 is drawing air, the first sealing member 30 can more effectively contact the mating surface 131, thereby ensuring the sealing effect of the first sealing member 30 on the gap between the shielding component 20 and the cover 13.

[0070] Please combine Figure 3 and Figure 7 In some embodiments, the shielding member 21 includes two connecting arms 211 and a shielding portion 213. One end of each of the two connecting arms 211 is rotatably connected to the cover 13. The shielding portion 213 is connected to the other end of each of the two connecting arms 211 and is disposed on the side where the mating surface 131 is located. When the connecting arms 211 rotate relative to the cover 13, the size of the gap between the shielding portion 213 and the surface to be cleaned is changed by moving the shielding portion 213, thereby changing the size of the opening of the suction port 113.

[0071] Specifically, in some embodiments, the shielding portion 213 may be flat or curved panel-shaped. In one example, when the shielding portion 213 is flat, the plane containing the shielding portion 213 is parallel to the height direction Z of the cleaning robot 1000, and in this case, the plane containing the shielding portion 213 is substantially perpendicular to the surface to be cleaned. In another example, when the shielding portion 213 is flat, the angle between the plane containing the shielding portion 213 in the direction away from the surface to be cleaned and the height direction Z of the cleaning robot 1000 is an acute angle, and the distance between the shielding portion 213 and the surface to be cleaned gradually increases in the forward direction X of the cleaning robot 1000. This facilitates the shielding portion 213 in gathering debris (such as dust or particulate matter) to the suction port 113, thereby improving the cleaning effect of the cleaning device 100.

[0072] In some embodiments, the connecting arm 211 and the shielding part 213 may be an integral structure, that is, the connecting arm 211 and the shielding part 213 may be integrally molded to form a single structure, thereby improving the bonding strength between the connecting arm 211 and the shielding part 213 and preventing cracking between the connecting arm 211 and the shielding part 213 during the cleaning process of the cleaning device 100, thereby improving the stability and reliability of the cleaning device 100 and the cleaning robot 1000. In other embodiments, the connecting arm 211 and the shielding part 213 may be separate structures, that is, the connecting arm 211 and the shielding part 213 are two different structures. The connecting arm 211 and the shielding part 213 may be combined using a non-detachable connection method or a detachable connection method, wherein the non-detachable connection method includes, but is not limited to, bonding or welding; the detachable connection method includes, but is not limited to, snap-fit ​​connection or threaded connection.

[0073] Please see Figure 3 and Figure 7 and combined Figure 3 and Figure 4 In some embodiments, the cleaning device 100 further includes a second seal 50, which is connected to the first seal 30 and disposed between the connecting arm 211 and the cover 13. The second seal 50 is used to seal the gap between the connecting arm 211 and the cover 13. This prevents external dust or sand and other impurities from entering the gap between the connecting arm 211 and the cover 13 and causing the shielding member 21 to jam, ensuring that the shielding member 21 can switch between a first shielding position and a second shielding position.

[0074] Furthermore, the second seal 50 prevents external dust, hair, and other contaminants from entering the gap between the connecting arm 211 and the cover 13, thus ensuring the cleanliness of the cleaning device 100 and improving its cleaning effect. For example, in one possible scenario, if contaminants are present in the gap between the connecting arm 211 and the cover 13, they can easily fall onto the cleaned surface, affecting the cleaning effect. Therefore, the second seal 50 enhances the cleaning effect of the cleaning device 100. It should be noted that in some embodiments, the material of the second seal 50 includes, but is not limited to, rubber, silicone, foam, and felt.

[0075] In some embodiments, the second seal 50 and the first seal 30 are an integral structure, meaning they can be integrally molded into a single structure, which facilitates their manufacturing. In other embodiments, the second seal 50 and the first seal 30 are separate structures, meaning they are two different structures. In this case, the second seal 50 and the first seal 30 can be combined using either a non-removable connection or a detachable connection. Non-removable connections include, but are not limited to, bonding or welding; detachable connections include, but are not limited to, snap-fit ​​connections or threaded connections. It is understood that in other embodiments, the second seal 50 and the first seal 30 may not be connected. In this case, the second seal 50 can be connected separately to the connecting arm 211, and the first seal 30 can be connected separately to the shielding part 213.

[0076] Please see Figure 4 In some embodiments, the body 300 is provided with a mounting housing 310 for accommodating at least a portion of the roller brush housing 10. Specifically, in some embodiments, the mounting housing 310 is provided with a mounting space 330, which is recessed from the side of the mounting housing 310 facing the surface to be cleaned in a direction away from the surface to be cleaned, and at least a portion of the roller brush housing 10 is disposed within the mounting space 330. The mounting space 330 reduces the space occupied by the cleaning device 100 and the body 300, thereby facilitating the miniaturization of the cleaning robot 1000; it also facilitates the mounting and positioning of the cleaning device 100 on the body 300, thereby improving the assembly efficiency of the cleaning device 100.

[0077] Typically, when the cleaning device 100 is installed on the mounting housing 310, a certain gap needs to be maintained between the two to prevent interference between the shielding component 20 and the mounting housing 310 during movement. However, when the cleaning device 100 is cleaning the surface to be cleaned, dust or other dirt can easily enter the gap between the shielding component 20 and the mounting housing 310, causing jamming and affecting the operation of the components, thus impacting the cleaning effect. For example, in one possible scenario, dirt in the gap between the shielding component 20 and the mounting housing 310 can easily fall onto the cleaned surface to be cleaned, affecting the cleaning effect.

[0078] In some embodiments of this disclosure, the cleaning device 100 further includes a third seal 60, which is disposed between the shield 21 and the mounting housing 310. The third seal 60 seals the gap between the shield 21 and the mounting housing 310. Therefore, the third seal 60 prevents external dust and other dirt from entering the gap between the shield 21 and the mounting housing 310, thereby ensuring the cleanliness of the cleaning robot 1000 and improving its cleaning effect. It should be noted that in some embodiments, the material of the third seal 60 includes, but is not limited to, rubber, silicone, and foam.

[0079] In some embodiments, one end of the third seal 60 is connected to the shield 21, and the other end of the third seal 60 is connected to the mounting housing 310. Specifically, in one example, at least a portion of the third seal 60 is elastic, capable of elastic deformation (extension and contraction) when the third seal 60 is subjected to force. During the movement of the shield 21 relative to the brush housing 10, the elastic deformation of the third seal 60 prevents it from interfering with the movement of the shield 21 relative to the brush housing 10 and ensures that the third seal 60 can seal the gap between the shield 21 and the mounting housing 310. In another example, the third seal 60 includes a pleated portion, which is generally a continuously bent curved surface structure capable of deformation under force. During the movement of the shielding member 21 relative to the roller brush housing 10, the pleated part can deform. This can prevent the third seal 60 from interfering with the movement of the shielding member 21 relative to the roller brush housing 10, and ensure that the third seal 60 can seal the gap between the shielding member 21 and the mounting housing 310.

[0080] In other embodiments, one end of the third seal 60 is connected to the shield 21, while the other end is not connected to the mounting housing 310. Specifically, the other end of the third seal 60 can contact the mounting housing 310, thereby sealing the gap between the shield 21 and the mounting housing 310. Furthermore, compared to having one end of the third seal 60 connected to the shield 21 and the other end connected to the mounting housing 310, the shield 21 is not affected by the third seal 60 when moving relative to the brush housing 10. This ensures the stability and reliability of the shield 21's movement relative to the brush housing 10, and reduces the power consumption required by the drive assembly 80 to drive the shield 21 relative to the brush housing 10, thus increasing the battery life of the cleaning robot 1000. For ease of explanation, the following embodiments will generally use the example of one end of the third seal 60 being connected to the shield 21 and the other end not being connected to the mounting housing 310.

[0081] Please combine Figure 5 In some embodiments, when the shielding member 21 is in the second shielding position, the third seal member 60 abuts against the inner wall of the mounting housing 310.

[0082] Specifically, in some embodiments, at least a portion of the third seal 60 is flexible. When the blocking member 21 moves relative to the cover 13 to the second blocking position, the third seal 60 can deform to abut against the inner wall of the mounting housing 310, thereby sealing the gap between the blocking member 21 and the mounting housing 310. It is understood that in some embodiments, the third seal 60 may remain abut against the inner wall of the mounting housing 310 during the movement of the blocking member 21 between the first and second blocking positions.

[0083] Furthermore, in some embodiments, the third seal 60 includes a body portion 61 and a bent portion 63. The body portion 61 is disposed on the blocking member 21. One end of the bent portion 63 is connected to the body portion 61, and the other end of the bent portion 63 is a free end. The free end has a protrusion 631 that protrudes relative to the body portion 61 toward the mounting housing 310. When the blocking member 21 is in the second blocking position, the protrusion 631 abuts against the mounting housing 310. Compared to a straight seal that is perpendicular to the compression direction, the bent portion 63 is bent and has a longer length. The deformation per unit length does not need to be large, so that when the bent portion 63 achieves a seal, its compression deformation does not require a large force, and it is not easy to get stuck. The protrusion 631 provides a tighter contact surface between the third seal 60 and the mounting housing 310, ensuring the sealing effect of the third seal 60 on the gap between the shield 21 and the mounting housing 310. On the other hand, it allows the third seal 60 to adapt to gaps of different sizes formed by assembly errors in the roller brush housing 10 on the mounting housing 310, thereby improving the reliability and stability of the seal.

[0084] In some embodiments, the third seal 60 and the first seal 30 are an integral structure, meaning they can be molded as a single unit, facilitating their manufacturing. In other embodiments, the third seal 60 and the first seal 30 are separate structures, meaning they are two distinct components. In this case, the third seal 60 and the first seal 30 can be joined together using either a non-removable or a detachable connection. Non-removable connections include, but are not limited to, bonding or welding; detachable connections include, but are not limited to, snap-fit ​​connections or threaded connections. It is understood that in other embodiments, the third seal 60 and the first seal 30 may not be connected; in this case, both the third seal 60 and the first seal 30 are individually connected to the shielding member 21.

[0085] In some embodiments, the first seal 30, the second seal 50, and the third seal 60 are an integral structure, that is, the first seal 30, the second seal 50, and the third seal 60 can be integrally molded into a single structure, which facilitates the processing and manufacturing of the first seal 30, the second seal 50, and the third seal 60. The first seal 30, the second seal 50, and the third seal 60 can be made of the same material, for example, silicone.

[0086] Please see Figure 4 and Figure 5In some embodiments, the shielding member 21 further includes a protrusion 215, which extends protruding from the shielding member 213 toward the mounting housing 310 or toward the opposite side of the cover 13. A mating portion 350 is provided on the inner wall of the mounting housing 310, extending protruding from the inner wall of the mounting housing 310 toward the center of the mounting housing 310. When the shielding member 21 is in the second shielding position, the protrusion 215 abuts against the mating portion 350 to seal the gap between the shielding member 21 and the mounting housing 310, preventing external dust and other dirt from entering the gap between the shielding member 21 and the mounting housing 310. This ensures the cleanliness of the cleaning robot 1000 and improves its cleaning effect.

[0087] Please see Figure 4 In some embodiments, the cleaning device 100 further includes a fourth seal 70, which is disposed between the roller brush chamber housing 11 and the cover 13 and is used to seal the gap between the roller brush chamber housing 11 and the cover 13. It should be noted that in some embodiments, the fourth seal 70 may include, but is not limited to, foam, felt, and sealing rings. The material of the sealing ring includes, but is not limited to, rubber or silicone.

[0088] Furthermore, please combine Figure 8 (view from above the cover) or Figure 9 (Viewed from below the brush housing) In some embodiments, the brush housing 11 has a first surface 115, and the cover 13 has a second surface 135. When the cover 13 is connected to the brush housing 11, the first surface 115 and the second surface 135 are opposite to each other. Exemplarily, the cover 13 can be connected to the brush housing 11 in a planar manner, meaning the cover 13 and the brush housing 11 are connected plane-to-plane, that is, the side of the cover 13 facing the brush housing 11 is connected to the side of the brush housing 11 facing the cover 13. Alternatively, the cover 13 can be embedded, semi-embedded, or enclosed / semi-enclosed to the brush housing 11, meaning at least a portion of the side of the cover 13 facing the brush housing 11 and its outer periphery in the thickness direction are connected to the brush housing 11. Exemplarily, the first surface 115 and the second surface 135 can be two surfaces that are vertically opposite each other in the height direction Z (see...). Figure 7 It can also be two opposite sides (see...). Figure 8 ).

[0089] Furthermore, please combine Figure 6In some embodiments, a fourth seal 70 is disposed between the first surface 115 and the second surface 135. Exemplarily, the fourth seal 70 covers at least a portion of the contact surface between the first surface 115 and the second surface 135, either completely or partially. Specifically, in some embodiments, the first surface 115 may be the connecting surface on the brush chamber housing 11 that connects to the cover 13, and the second surface 135 may be the connecting surface on the cover 13 that connects to the brush chamber housing 11. In the height direction Z of the cleaning robot 1000, the first surface 115 and the second surface 135 are opposite each other. Therefore, with the fourth seal 70 positioned between the first surface 115 and the second surface 135, the fourth seal 70 prevents the receiving cavity 111 from communicating with the outside through the gap at the connection between the roller brush housing 11 and the cover 13. This improves the airtightness of the receiving cavity 111, making it easier to form a high vacuum when the fan 40 is drawing air, thereby enhancing the cleaning effect of the cleaning device 100. It is understood that in this embodiment, the fourth seal 70 can be a sealing ring.

[0090] And / or, please combine Figure 7 In other embodiments, a fourth seal 70 is disposed between the inner wall of the receiving cavity 111 and the cover 13 to seal the gap between the first surface 115 and the second surface 135.

[0091] Specifically, in this embodiment, when the roller brush chamber shell 11 and the cover 13 are connected, at least a portion of the cover 13 is located in the receiving cavity 111. In this case, the first surface 115 can be the inner wall of the receiving cavity 111 in the direction perpendicular to the height direction Z of the cleaning robot 1000, and the second surface 135 can be the side wall of the cover 13 in the direction perpendicular to the height direction Z of the cleaning robot 1000. Thus, with the fourth seal 70 disposed between the first surface 115 and the second surface 135, the fourth seal 70 can prevent external dust or sand and other impurities from entering the gap between the inner wall of the receiving cavity 111 and the cover 13, causing the blocking member 21 to jam. This ensures that the blocking member 21 can switch between a first blocking position and a second blocking position.

[0092] Furthermore, the fourth seal 70 prevents external dust, hair, and other contaminants from entering the gap between the inner wall of the receiving cavity 111 and the cover 13, thereby ensuring the cleanliness of the cleaning device 100 and improving its cleaning effect. For example, in one possible scenario, if contaminants are present in the gap between the inner wall of the receiving cavity 111 and the cover 13, these contaminants can easily fall onto the cleaned surface, affecting the cleaning effect. Therefore, the fourth seal 70 improves the cleaning effect of the cleaning device 100. It is understood that in this embodiment, the fourth seal 70 can be a brush strip or foam, etc.

[0093] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present disclosure.
