[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. Generally, a cleaning robot consists of a cleaning unit, which includes cleaning components (such as roller brushes) capable of cleaning the surface. However, the cleaning unit can only perform a simple cleaning, resulting in limited applicability and inability to meet user needs. Utility Model Content

[0003] This disclosure provides a cleaning device, a cleaning robot, and a cleaning system, which at least address the problem of poor applicability of the aforementioned cleaning robot.

[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 roller brush assembly is at least partially disposed within the roller brush housing and is connected to the drive assembly. The shielding assembly is connected to the drive assembly. The lifting assembly is connected to the drive assembly and the roller brush housing. The drive assembly is used to drive the roller brush assembly to rotate to clean the surface to be cleaned, drive the shielding assembly to move to change the opening size of the suction inlet, and drive the lifting assembly to move to drive the roller brush housing to move, thereby causing the cleaning device to rise and fall relative to the body.

[0007] The cleaning device, cleaning robot, and cleaning system disclosed herein include a roller brush assembly, a shielding assembly, and a lifting assembly. A driving assembly is used to drive the roller brush assembly to rotate to clean the surface to be cleaned, to drive the shielding assembly to move to change the opening size of the suction inlet, and to drive the lifting assembly to move the roller brush housing, thereby causing the cleaning device to rise and fall relative to the main body. Thus, compared with related technologies, the cleaning device can not only clean the surface to be cleaned, but also use the roller brush assembly, shielding assembly, and lifting assembly to perform other functions, thereby improving the applicability of the cleaning robot, meeting the user's needs, and improving the cleaning effect.

Detailed Implementation

[0038] 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.

[0039] 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. Generally, a cleaning robot includes a cleaning device, which in turn includes cleaning components (such as a roller brush assembly) capable of cleaning the surface to be cleaned. However, the cleaning device can only perform basic cleaning, resulting in limited applicability and failing to meet user needs. To address this issue of limited applicability, this disclosure provides a cleaning device 100 (… Figure 1 , Figure 12 or Figure 15 (as shown), 1000 cleaning robots ( Figure 20 (as shown) and cleaning system 4000 ( Figure 21 (As shown).

[0040] Please see Figures 1 to 3 and combined Figure 20 This disclosure provides a cleaning device 100 for use with a cleaning robot 1000. When performing a cleaning task, the cleaning robot 1000 uses the cleaning device 100 to clean debris from a surface to be cleaned. The cleaning device 100 includes a roller brush housing 10, a drive assembly 20, a roller brush assembly 40, a shielding assembly 50, and a lifting assembly 60. The roller brush housing 10 is disposed on the body 200 of the cleaning robot 1000 and has a suction port 11. The suction port 11 faces the surface to be cleaned and is used to allow debris from the surface to be cleaned to enter the roller brush housing 10. The drive assembly 20 is disposed on the roller brush housing 10 or the body 200. The roller brush assembly 40 is at least partially disposed within the roller brush housing 10 and is connected to the drive assembly 20. The shielding assembly 50 is connected to the drive assembly 20. The lifting assembly 60 is connected to the drive assembly 20 and the roller brush housing 10. The drive assembly 20 is used to drive the roller brush assembly 40 to rotate to clean the surface to be cleaned, drive the shielding assembly 50 to move to change the opening size of the suction port 11, and drive the lifting assembly 60 to move to drive the roller brush housing 10 to move, thereby causing the roller brush assembly 40 to rise and fall relative to the body 200.

[0041] It should be noted that, in some embodiments, 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. The body 200 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 200 can be made of both metallic and non-metallic materials, thereby increasing the structural strength of the body 200, preventing collision damage during operation, and improving the stability and reliability of the cleaning robot 1000. In another example, the body 200 can be made of non-metallic materials, such as plastic, thereby reducing its weight and making the cleaning robot 1000 more portable.

[0042] The cleaning device 100 is a device that enables the cleaning robot 1000 to perform mopping or sweeping functions. That is, the cleaning device 100 can mop 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 also be the surface of other objects that need cleaning, such as walls, beds, windows, etc.

[0043] The material of the roller brush housing 10 can be a metallic material and / or a non-metallic material, wherein the metallic material includes, but is not limited to, aluminum, iron, steel or aluminum alloy, and the non-metallic material includes, but is not limited to, plastic. 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 11 is opposite to the surface to be cleaned, and 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 200 is spaced apart from (not in contact with) the surface to be cleaned, while the end of the roller brush housing 10 near the rear end of the body 200 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 11 near the front end of the body 200 is not in contact with the surface to be cleaned, while the end of the suction port 11 near the rear end of the body 200 is in contact with the surface to be cleaned. This ensures that as much garbage as possible can be sucked into the roller brush housing 10 through the suction port 11. Compared to the case where the side of the suction port 11 near the rear end of the body 200 is in contact with the surface to be cleaned, the cleaning device 100 in this embodiment can clean up large garbage and is less likely to miss garbage, thereby improving the cleaning effect of the cleaning device 100.

[0044] Furthermore, in some embodiments, see Figure 7The roller brush housing 10 includes a cover 12 that covers the suction port 11. The cover 12 includes a first side 103 and a second side 105, with the first side 103 being closer to the front end of the cleaning robot 1000 than the second side 105. When the cleaning robot 1000 performs a cleaning task, the first side 103 does not contact the surface to be cleaned, while the second side 105 does. For example, at least a portion of the first side 103 may be tilted relative to the second side 105. This allows the end of the suction port 11 near the front end of the body 200 in the above embodiment to not contact the surface to be cleaned, while the end of the suction port 11 near the rear end of the body 200 contacts the surface to be cleaned.

[0045] 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 200 closest to the forward direction X is the front end of the body 200, and the rear end of the body 200 closest to the forward direction X is the rear end of the body 200.

[0046] The drive assembly 20 is a structure in the cleaning device 100 that can provide power to some of its components. In some embodiments of this disclosure, when the drive assembly 20 is moving stably, the driving force generated by the drive assembly 20 can act on the roller brush assembly 40, the shielding assembly 50, and the lifting assembly 60 to drive the roller brush assembly 40 to rotate to clean the surface to be cleaned, drive the shielding assembly 50 to move to change the opening size of the suction port 11, and drive the lifting assembly 60 to move to drive the roller brush housing 10 to move, thereby causing the roller brush assembly 40 to rise and fall relative to the body 200.

[0047] In some embodiments, see Figure 3 The roller brush housing 10 also includes a roller brush cavity housing 14 and a cover 12. The roller brush cavity housing 14 has a receiving cavity 18 and a suction port 11 communicating with the receiving cavity 18. The cover 12 is detachably connected to the roller brush cavity housing 14. The cover 12 can be connected to the roller brush cavity housing 14 by a detachable connection method such as snap-fit ​​connection or bolt connection.

[0048] The roller brush assembly 40 includes a roller brush 41, which is disposed within the receiving cavity 18 and contacts the surface to be cleaned through the suction port 11. When the driving force generated by the drive assembly 20 is transmitted to the roller brush 41, the roller brush 41 rotates relative to the roller brush cavity housing 14 under the drive of the drive assembly 20. In this way, the roller brush 41 can sweep away the debris on the surface to be cleaned, and the debris can be sucked into the receiving cavity 18 through the suction port 11 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 11 can be the size of the opening on the roller brush housing 10 for allowing debris to enter the receiving cavity 18 during the cleaning process of the cleaning device 100 sweeping the surface to be cleaned.

[0049] Furthermore, in some embodiments, see Figure 1-2 The roller brush housing 10 is also provided with a suction port 19, which is connected to the receiving cavity 18. The suction port 19 is used to allow the waste in the receiving cavity to move out of the receiving cavity 18. Specifically, when waste enters the receiving cavity 18, the waste in the receiving cavity 18 can be moved out of the receiving cavity 18 through the suction port 19 under the action of the suction airflow and enter the waste collection container (e.g., dust box) of the cleaning robot 1000.

[0050] Since the size of the suction port 11 has a certain impact on the vacuum between the surface to be cleaned and the receiving cavity 18, specifically, the larger the opening of the suction port 11, the smaller the suction force of the receiving cavity 18, the lower the cleaning efficiency of the cleaning device 100, and the more difficult it is for the garbage to be sucked into the receiving cavity 18; the smaller the opening of the suction port 11, the greater the suction force of the receiving cavity 18, the higher the cleaning efficiency of the cleaning device 100, and the easier it is for the garbage to be sucked into the receiving cavity 18. In other words, when cleaning the garbage on the same surface to be cleaned, the larger the opening of the suction port 11, the greater the suction force required. Therefore, in some embodiments of this disclosure, the drive component 20 can drive the blocking component 50 to move to change the opening size of the suction port 11, thereby adjusting the cleaning efficiency of the cleaning device 100. Thus, the cleaning device 100 can adjust the opening size of the suction port 11 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 18, 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.

[0051] In some implementations, the surface to be cleaned includes target areas and non-target areas. Target areas can refer to areas requiring deep cleaning, such as carpeted areas, floor mat areas, foot mat areas, yoga mat areas, rubber mat areas, straw or bamboo mat areas, heavily soiled areas, user-defined areas, etc. Non-target areas can refer to areas that do not require deep cleaning, or can be other areas besides the target areas, such as areas without carpets or open ground. For example, the target area is a carpeted area, and the non-target area is a non-carpeted area. Since debris (such as dust or small impurities) in the target area is easily hidden in the carpet fibers, it can be understood that the carpet has a strong adsorption capacity for debris. Therefore, when cleaning the target area, a large suction force is required, and the opening of the suction inlet 11 needs to be in a smaller state to increase the vacuum between the surface to be cleaned and the receiving cavity 18, thus ensuring the cleaning effect. On the other hand, since non-target areas are usually smoother, when cleaning non-target areas, the opening of the suction inlet 11 can be in a larger state, so that the suction force of the receiving cavity 18 can meet the cleaning requirements. Furthermore, having a larger opening of the suction inlet 11 can also ensure that debris can enter the receiving cavity 18 through the suction inlet 11, preventing large debris from being blocked outside the suction inlet 11.

[0052] Therefore, please combine Figure 21 In some embodiments of this disclosure, when the current position of the cleaning robot 1000 is a target area, and the cleaning process switches from cleaning a target area to cleaning a non-target area, the drive component 20 drives the blocking component 50 to move to increase the opening size of the suction inlet 11, and drives the roller brush assembly 40 to rotate to clean the non-target area. And / or, when the current position of the cleaning robot 1000 is a non-target area, and the cleaning process switches from cleaning a non-target area to cleaning a target area, the drive component 20 drives the blocking component 50 to move to decrease the opening size of the suction inlet 11, and drives the roller brush assembly 40 to rotate to clean the target area. And / or, during at least a portion of the time that the cleaning robot 1000 is crossing an obstacle or entering / exiting the base station 3000 or mopping, the drive component 20 drives the lifting component 60 to move so as to raise the roller brush component 40 relative to the body 200; and / or, after the cleaning robot 1000 has crossed an obstacle or entered / exited the base station 3000 or during at least a portion of the time that it is sweeping, the drive component 20 drives the lifting component 60 to move so as to lower the roller brush component 40 relative to the body 200.

[0053] For the cleaning robot 1000, since the brush assembly 40 needs to contact the surface to be cleaned when the cleaning device 100 is used to perform the sweeping function, it is desirable that the brush assembly 40 of the cleaning device 100 is raised or not in contact with the surface to be cleaned when the cleaning robot 1000 encounters obstacles, enters or exits the base station 3000, or is used to perform the mopping function. This is to facilitate overcoming obstacles, climbing slopes when entering or exiting the base station 3000, or preventing the brush assembly 40 from getting wet and affecting the cleaning effect during mopping. Therefore, in some embodiments of this disclosure, during at least a portion of the time when the cleaning robot 1000 is crossing obstacles, entering or exiting the base station 3000, or mopping, the drive assembly 20 drives the lifting assembly 60 to move so as to raise the brush assembly 40 relative to the body 200. For example, when there are obstacles on the surface to be cleaned, the drive component 20 drives the lifting component 60 to move, causing the roller brush component 40 to rise relative to the body 200. This facilitates the cleaning robot 1000 in overcoming obstacles, improving its passability; it also helps the cleaning robot 1000 adapt to different cleaning environments, improving its cleaning effect. It is understood that in some embodiments, after the cleaning robot 1000 has overcome an obstacle, entered or exited the base station 3000, or during at least a portion of the sweeping period, the drive component 20 drives the lifting component 60 to move, causing the roller brush component 40 to descend relative to the body 200. This ensures that the roller brush component 40 cleans the surface to be cleaned properly.

[0054] In the cleaning device 100 of this embodiment, the cleaning device 100 includes a roller brush assembly 40, a shielding assembly 50, and a lifting assembly 60. The driving assembly 20 is used to drive the roller brush assembly 40 to rotate to clean the surface to be cleaned, drive the shielding assembly 50 to move to change the opening size of the suction port 11, and drive the lifting assembly 60 to move to drive the roller brush housing 10 to move, thereby causing the roller brush assembly 40 to rise and fall relative to the body 200. Thus, compared with related technologies, the cleaning device 100 can not only clean the surface to be cleaned, but also use the roller brush assembly 40, the shielding assembly 50, and the lifting assembly 60 to perform other functions, thereby improving the applicability of the cleaning robot 1000, meeting the user's needs, and improving the cleaning effect.

[0055] The cleaning device 100 will be further explained below with reference to the accompanying drawings.

[0056] Please see Figure 1 and Figure 2In some embodiments, the drive assembly 20 includes a drive member 21, which drives the roller brush assembly 40 to rotate to clean the surface to be cleaned, drives the shielding assembly 50 to move to change the opening size of the suction port 11, and drives the lifting assembly 60 to move to drive the roller brush housing 10 to move, thereby causing the roller brush assembly 40 to rise and fall relative to the body 200.

[0057] Specifically, in some embodiments, when the driving component 21 is operating stably, the driving component 21 can output driving force, and the driving force can be transmitted to the roller brush assembly 40, the blocking assembly 50, and the lifting assembly 60 to drive the roller brush assembly 40, the blocking assembly 50, and the lifting assembly 60 to move. The driving component 21 can be disposed on the roller brush housing 10 or the body 200. The driving component 21 and the roller brush housing 10 or the body 200 can be connected together using a detachable or non-detachable connection method. Non-detachable connection methods include, but are not limited to, bonding or welding; detachable connection methods include, but are not limited to, snap-fit ​​connections or threaded connections. It should be noted that in some embodiments, the driving component 21 can be a motor or an electric actuator, wherein the motor includes, but is not limited to, a DC servo motor, an AC servo motor, and a stepper motor.

[0058] More specifically, in some embodiments, the drive assembly 20 includes at least two drive members 21. For example, the drive assembly 20 includes two drive members 21. In this case, both drive members 21 can drive the roller brush assembly 40 to rotate to clean the surface to be cleaned, drive the shielding assembly 50 to move to change the opening size of the suction inlet, and drive the lifting assembly 60 to move the roller brush housing 10, thereby causing the roller brush assembly 40 to rise and fall relative to the body 200. For instance, one of the two drive members 21 can drive the roller brush assembly 40 to rotate to clean the surface to be cleaned, drive the shielding assembly 50 to move to increase the opening size of the suction inlet 11, and drive the lifting assembly 60 to move to raise the roller brush assembly 40 relative to the body 200; the other of the two drive members 21 can drive the roller brush assembly 40 to rotate to clean the surface to be cleaned, drive the shielding assembly 50 to move to decrease the opening size of the suction inlet 11, and drive the lifting assembly 60 to move to lower the roller brush assembly 40 relative to the body 200. For example, one of the two drive components 21 can drive the movement of one of the roller brush assembly 40, the blocking assembly 50, and the lifting assembly 60, while the other can drive the remaining two movements of the roller brush assembly 40, the blocking assembly 50, and the lifting assembly 60.

[0059] In some embodiments, the drive assembly 20 includes only one drive member 21. That is, one drive member 21 can simultaneously drive the roller brush assembly 40, the blocking assembly 50, and the lifting assembly 60 to move. Therefore, the movement of the roller brush assembly 40, the blocking assembly 50, and the lifting assembly 60 can be achieved with only one power source, such as a motor. This reduces the size of the cleaning device 100 and the cleaning robot 1000. Figure 20 The reduced production cost (as shown) helps improve the competitiveness of the cleaning robot 1000. Furthermore, due to the smaller number of power sources, the space occupied by the cleaning robot 1000 can be minimized, resulting in fewer components in both the cleaning device 100 and the cleaning robot 1000, and easier disassembly, assembly, and maintenance, thus facilitating the miniaturization of both. For ease of explanation, the following embodiment will only use a single drive component 21 included in the drive assembly 20 as an example.

[0060] Please continue reading. Figure 1 and Figure 2 Furthermore, in some embodiments, the drive assembly 20 further includes a transmission component 23. The transmission component 23 is connected to the output end of the drive member 21 and is used to transmit the driving force of the drive member 21 to the roller brush assembly 40, the blocking assembly 50, and the lifting assembly 60. Specifically, in some embodiments, when the drive member 21 is operating stably, the drive member 21 can output a driving force, and the driving force can be transmitted through the transmission component 23 to the roller brush assembly 40, the blocking assembly 50, and the lifting assembly 60 to drive the roller brush assembly 40, the blocking assembly 50, and the lifting assembly 60 to move.

[0061] In some embodiments, when the output end of the drive member 21 rotates in a first rotation direction, the transmission member 23 transmits the driving force of the drive member 21 to the roller brush assembly 40, which can drive the roller brush 41 to rotate to clean the surface to be cleaned. When the output end of the drive member 21 rotates in a second rotation direction, the transmission member 23 transmits the driving force of the drive member 21 to at least the shielding assembly 50 or the lifting assembly 60, and the first rotation direction and the second rotation direction are opposite. It should be noted that in some embodiments, when the drive member 21 is a motor, the output end of the drive member 21 is the output shaft of the drive member 21.

[0062] Specifically, in some embodiments, when the output shaft of the drive member 21 rotates in the first rotation direction, the transmission member 23 can transmit the driving force of the drive member 21 to the roller brush assembly 40 to drive the roller brush assembly 40 to move and clean the surface to be cleaned. In this case, the transmission member 23 will not transmit the driving force of the drive member 21 to the shielding assembly 50 and the lifting assembly 60, that is, the shielding assembly 50 and the lifting assembly 60 remain in a stopped state. When the output shaft of the drive member 21 rotates in the second rotation direction, the transmission member 23 can transmit the driving force of the drive member 21 to the shielding assembly 50 to drive the shielding assembly 50 to move and change the opening size of the suction port 11; or, transmit the driving force of the drive member 21 to the lifting assembly 60 to drive the lifting assembly 60 to move and drive the roller brush assembly 40 to rise and fall relative to the body 200; or, transmit the driving force of the drive member 21 to the roller brush assembly 40 to drive the roller brush assembly 40 to rotate. Therefore, the cleaning device 100 can achieve different functions by controlling the rotation direction of the output end of the drive unit 21, thereby improving the cleaning robot 1000 ( Figure 20 (As shown) Applicability.

[0063] In some embodiments, as the output end of the drive member 21 rotates in a first rotation direction, the roller brush assembly 40 rotates in a first direction. As the output end of the drive member 21 rotates in a second rotation direction, the roller brush assembly 40 rotates in a second direction, and the cleaning device 100 includes at least one of a first state, a second state, and a third state, where the first direction is opposite to the second direction. Specifically: in the first state, the drive member 21 drives the blocking assembly 50 to move to change the opening size of the suction inlet 11; in the second state, the drive member 21 does not drive the blocking assembly 50 to move, nor does it drive the lifting assembly 60 to move; in the third state, the drive member 21 drives the lifting assembly 60 to move to raise and lower the roller brush assembly 40 relative to the body 200.

[0064] Specifically, the cleaning device 100 includes the following states: In a first state, the drive member 21 drives the blocking assembly 50 to move, thereby reducing or increasing the opening size of the suction inlet 11; in a second state, the drive member 21 does not drive the blocking assembly 50 to move, nor does it drive the lifting assembly 60 to move; in a third state, the drive member 21 drives the lifting assembly 60 to move, thereby causing the roller brush assembly 40 to rise or fall relative to the body 200. For example, the cleaning robot 1000 includes a deep cleaning mode, a normal cleaning mode, and a lifting mode. Specifically, during the process of the cleaning robot 100 switching from deep cleaning mode to normal cleaning mode, the drive component 21 drives the shielding component 50 to move, thereby increasing the opening size of the suction inlet 11; during the process of the cleaning robot 1000 switching from normal cleaning mode to lifting mode, the drive component 21 drives the lifting component 60 to move, thereby causing the roller brush component 40 to rise relative to the body 200; during the process of the cleaning robot 1000 switching from lifting mode to normal cleaning mode, the drive component 21 drives the lifting component 60 to move, thereby causing the roller brush component 40 to fall relative to the body 200; during the process of the cleaning robot 1000 switching from normal cleaning mode to deep cleaning mode, the drive component 21 drives the shielding component 50 to move, thereby increasing the opening size of the suction inlet 1 ... 0. Movement to reduce the opening size of the suction inlet 11; During the process of the cleaning robot 1000 switching from deep cleaning mode to lifting mode, the drive component 21 drives the shielding component 50 to move to increase the opening size of the suction inlet 11, and drives the lifting component 60 to move to drive the roller brush component 40 to rise relative to the body 200, so as to drive the roller brush component 40 to rise relative to the body 200; During the process of the cleaning robot 1000 switching from lifting mode to deep cleaning mode, the drive component 21 drives the shielding component 50 to move to reduce the opening size of the suction inlet 11, and drives the lifting component 60 to move to drive the roller brush component 40 to fall relative to the body 200, so as to drive the roller brush component 40 to fall relative to the body 200.

[0065] Specifically, in some embodiments, as the output end of the drive unit 21 rotates along the first rotation direction, the roller brush assembly 40 rotates along the first direction. At this time, the roller brush assembly 40 can clean the surface to be cleaned, and the cleaning device 100 can realize the sweeping function of the cleaning robot 1000. More specifically, the opening size of the suction port 11 in the normal cleaning mode and the lifting mode is larger than the opening size of the suction port 11 in the deep cleaning mode; the height of the roller brush assembly 40 relative to the body 200 in the deep cleaning mode and the normal cleaning mode is smaller than the height of the roller brush assembly 40 relative to the body 200 in the lifting mode. Thus, in the deep cleaning mode, the roller brush assembly 40 can perform deep cleaning of the surface to be cleaned (e.g., the target area); in the normal cleaning mode, the roller brush assembly 40 can perform routine cleaning of the surface to be cleaned (e.g., the non-target area); in the lifting mode, the roller brush assembly 40 can be lifted relative to the body 200 to facilitate obstacle crossing, entering and exiting the base station, or performing mopping tasks, etc. During the rotation of the output end of the drive unit 21 along the second rotation direction, the cleaning device 100 can switch between deep cleaning mode, normal cleaning mode and lifting mode, so that the cleaning device 100 can be used in different working scenarios, improve the applicability of the cleaning device 100 and ensure the cleaning effect of the cleaning device 100.

[0066] Please see Figures 1 to 3 In some embodiments, the transmission component 23 includes a first output end. The blocking assembly 50 includes a blocking component 501, which is connected to the first output end of the transmission component 23. The blocking component 501 is movable relative to the roller brush housing 10 to change the opening size of the suction port 11. It should be noted that in some embodiments, the first output end of the transmission component 23 may be a portion of the transmission component 23 that cooperates with the blocking component 501 and is capable of transmitting the driving force of the drive member 21 to the blocking component 50.

[0067] Specifically, in some embodiments, when the output end of the drive member 21 rotates in the second rotation direction, the driving force of the drive member 21 can be transmitted to the blocking member 501 through the first output end of the transmission member 23, and drive the blocking member 501 to move relative to the roller brush housing 10 to change the opening size of the suction port 11, thereby enabling the cleaning robot 1000 to be adapted to different working scenarios. That is, whether the current position of the cleaning robot 1000 is in the target area or a non-target area, the cleaning robot 1000 can effectively clean the surface to be cleaned, thereby improving the cleaning effect of the cleaning robot 1000.

[0068] Furthermore, please combine Figure 3 and Figure 4In some embodiments, the blocking member 501 includes a blocking member 51 and a connecting member 53. The blocking member 51 is connected to the roller brush housing 10 and is used to block the opening of the suction port 11. One end of the connecting member 53 is connected to the first output end of the transmission member 23, and the other end of the connecting member 53 is connected to the blocking member 51. When the connecting member 53 moves along the first direction (A1 / A2), the blocking member 51 moves relative to the roller brush housing 10 to a first blocking position ( Figure 3 (as shown) and the second occlusion position ( Figure 4 The size of the inlet 11 when the shielding member 51 is in the first shielding position is greater than the size of the inlet 11 when the shielding member 51 is in the second shielding position.

[0069] Specifically, in some embodiments, when the output end of the drive member 21 rotates in the second rotation direction, the driving force of the drive member 21 can be transmitted to the connector 53 through the first output end of the transmission member 23, and drive the connector 53 to move relative to the roller brush housing 10 in the first direction (A1 / A2), so as to drive the blocking member 51 to move relative to the roller brush housing 10, thereby switching the blocking member 51 between the first blocking position and the second blocking position to change the opening size of the suction port 11, thereby changing the vacuum degree between the surface to be cleaned and the receiving cavity 18 during operation, so that the cleaning robot 1000 can be adapted to different working scenarios and improve the cleaning effect.

[0070] It should be noted that, in some embodiments, the cross section of the shielding member 51 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 11 cut by a plane perpendicular to the forward direction X of the cleaning robot 1000. Thus, during the process of the shielding member 51 switching from the first shielding position to the second shielding position, the shielding member 51 can effectively shield the suction port 11 to reduce the opening size of the suction port 11.

[0071] Optionally, the shielding member 51 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 debris from the surface to be cleaned, the shielding member 51 can undergo a certain elastic deformation to allow the debris to smoothly pass through the suction port 11 into the receiving cavity 18, thereby preventing the shielding member 51 from obstructing the debris and improving the cleaning effect. Furthermore, using an elastic material also prevents the shielding member 51 from rigidly colliding with harder debris or the surface to be cleaned, thus extending its service life and ensuring the normal operation of the shielding assembly 50. Of course, in other embodiments, the shielding member 51 can also be made of a non-elastic material.

[0072] Please see Figure 2In some embodiments, the roller brush housing 10 is provided with a guide 15 for guiding the connector 53 to move along a first direction (A1 / A2). One of the guide 15 and the connector 53 has a guide groove, and the other has a guide post, at least a portion of which is received within the guide groove, and the two are slidably connected. Exemplarily, the guide 15 has a guide groove, the connector 53 has a guide post, the guide 15 receives at least a portion of the connector 53, and guides the connector 53 to move along the first direction (A1 / A2).

[0073] Specifically, in some embodiments, the guide member 15 is provided with a guide groove, and the connector 53 is provided with a guide post. The guide member 15 can be recessed from the outer side wall of the roller brush housing 10 toward the receiving cavity 18 of the roller brush housing 10. At least a portion of the connector 53 is disposed in the guide member 15. Thus, while guiding the connector 53 to move along the first direction (A1 / A2), the guide member 15 can also limit the moving direction and travel of the connector 53 relative to the roller brush housing 10. This prevents the moving direction and travel of the connector 53 in the first direction (A1 / A2) from being unrestricted when the program of the drive member 21 malfunctions, which could lead to the connector 53 colliding and being damaged with other structures of the cleaning device 100. This ensures the stability and reliability of the cleaning device 100.

[0074] Please combine Figure 5 In some embodiments, in a direction perpendicular to the first direction (A1 / A2), the guide member 15 includes opposing first guide sidewalls 151 and second guide sidewalls 153, and the connector 53 includes opposing first connecting sidewalls 535 and second connecting sidewalls 536. The first connecting sidewall 535 and the first guide sidewall 151 are slidably engaged, and the second connecting sidewall 536 and the second guide sidewall 153 are also slidably engaged. Further, in some embodiments, one of the first connecting sidewall 535 and the first guide sidewall 151 is provided with a guide groove, and the other with a guide post; one of the second connecting sidewall 536 and the second guide sidewall 153 is provided with a guide groove, and the other with a guide post. For example, the first connecting sidewall 535 is provided with a guide post, and the first guide sidewall 151 is provided with a guide groove; the second connecting sidewall 536 is provided with a guide post, and the second guide sidewall 153 is provided with a guide groove. This reduces the resistance of the connector 53 sliding in the guide 15, reduces the power consumption required for the drive assembly 20 to drive the shielding component 501, and increases the battery life of the cleaning robot 1000. On the other hand, it reduces the possibility of the connector 53 getting stuck in the guide 15, ensures the normal movement of the connector 53 along the first direction (A1 / A2), and improves the stability and reliability of the shielding component 501.

[0075] Furthermore, in some embodiments, a first protruding structure 537 is provided on the first connecting sidewall 535. The first protruding structure 537 extends from the first connecting sidewall 535 in a direction away from the second connecting sidewall 536 and abuts against the first guiding sidewall 151.

[0076] Specifically, the first protruding structure 537 may include multiple spaced protrusions. The protrusions extend from the first connecting sidewall 535 in a direction away from the second connecting sidewall 536. When the connector 53 is disposed in the guide member 15, the protrusions abut against the first guide sidewall 151. Thus, compared to the first connecting sidewall 535 directly abutting against the first guide sidewall 151, the arrangement of the first protruding structure 537 can reduce the contact area between the first connecting sidewall 535 and the first guide sidewall 151, thereby reducing the friction between the connector 53 and the guide member 15. This can reduce the power consumption required for the drive assembly 20 to drive the blocking member 501 to move, increasing the battery life of the cleaning robot 1000. On the other hand, it can reduce the possibility of the connector 53 getting stuck in the guide member 15, ensuring the normal movement of the connector 53 along the first direction (A1 / A2), and improving the stability and reliability of the blocking member 501.

[0077] It is understood that in other embodiments, a first protruding structure 537 may be provided on the first guide sidewall 151. The first protruding structure 537 protrudes from the first guide sidewall 151 toward the direction close to the second guide sidewall 153, and abuts against the first connecting sidewall 535. The structure of the first protruding structure 537 in this embodiment is basically the same as that in the above embodiments, and will not be described in detail here.

[0078] In some embodiments, a second protruding structure is provided on the second connecting sidewall 536. The second protruding structure extends from the second connecting sidewall 536 in a direction away from the first connecting sidewall 535 and abuts against the second guiding sidewall 153.

[0079] Specifically, the second protruding structure may include multiple spaced protrusions. The protrusions extend from the second connecting sidewall 536 in a direction away from the first connecting sidewall 535. When the connector 53 is disposed in the guide 15, the protrusions abut against the second guide sidewall 153. Thus, compared to the second connecting sidewall 536 directly abutting against the second guide sidewall 153, the second protruding structure can reduce the contact area between the second connecting sidewall 536 and the second guide sidewall 153, thereby reducing the friction between the connector 53 and the guide 15. This can reduce the power consumption required for the drive assembly 20 to drive the blocking component 501 to move, increasing the battery life of the cleaning robot 1000. On the other hand, it can reduce the possibility of the connector 53 getting stuck in the guide 15, ensuring the normal movement of the connector 53 along the first direction (A1 / A2), and improving the stability and reliability of the blocking component 501.

[0080] It is understood that in other embodiments, a second protruding structure is provided on the second guide sidewall 153. The second protruding structure extends from the second guide sidewall 153 toward the first guide sidewall 151 and abuts against the second connecting sidewall 536. The structure of the second protruding structure in this embodiment is basically the same as that in the above embodiments, and will not be described in detail here.

[0081] Please see Figures 1 to 4 In some embodiments, the shielding member 51 is rotatably connected to the cover 12. The shielding member 51 does not contact the surface to be cleaned in the first shielding position, and the shielding member 51 contacts the surface to be cleaned in the second shielding position.

[0082] Specifically, in some embodiments, when the driving force output by the drive member 21 is transmitted to the blocking member 51 at the first output end of the transmission member 23, the blocking member 51 can rotate relative to the cover 12 to move between a first blocking position and a second blocking position. In the first blocking position, the blocking member 51 is not in contact with the surface to be cleaned; at this time, the opening of the suction inlet 11 is relatively large, and the current position of the cleaning robot 1000 can be a non-target area. In the second blocking position, the blocking member 51 is in contact with the surface to be cleaned; at this time, the opening of the suction inlet 11 is relatively small, and the current position of the cleaning robot 1000 can be the target area.

[0083] Furthermore, please combine Figure 5In some embodiments, the shielding member 51 includes two connecting arms 511 and a shielding portion 513. One end of each connecting arm 511 is rotatably connected to the cover 12, and the shielding portion 513 is connected to the other end of each connecting arm 511. For example, the shielding member 51 is U-shaped. The shielding portion 513 is located on the side of the first side 103 of the cover 12. When the connecting arms 511 rotate relative to the cover 12, the size of the gap between the shielding portion 513 and the surface to be cleaned is changed by moving the shielding portion 513, thereby changing the opening size of the suction port 11. For example, the opening size of the suction port 11 can be the height of the shielding portion 513 and the surface to be cleaned in a direction perpendicular to the surface to be cleaned. That is, the greater the height of the shielding portion 513 from the surface to be cleaned in a direction perpendicular to the surface to be cleaned, the larger the opening size of the corresponding suction port 13.

[0084] Specifically, in some embodiments, the shielding portion 513 may be flat or curved. In one example, when the shielding portion 513 is flat, the plane on which the shielding portion 513 is located is parallel to the height direction of the cleaning robot 1000, and in this case, the plane on which the shielding portion 513 is located is substantially perpendicular to the surface to be cleaned. In another example, when the shielding portion 513 is flat, the angle between the plane on which the shielding portion 513 is located and the height direction of the cleaning robot 1000 is an acute angle, and the distance between the shielding portion 513 and the surface to be cleaned gradually increases in the forward direction X of the cleaning robot 1000. This facilitates the shielding portion 513 in gathering debris (such as dust or particulate matter) to the suction port 11, thereby improving the cleaning effect of the cleaning device 100.

[0085] In some embodiments, the connecting arm 511 and the shielding part 513 may be an integral structure, that is, the connecting arm 511 and the shielding part 513 may be integrally molded to form a single structure, thereby improving the bonding strength between the connecting arm 511 and the shielding part 513 and preventing cracking between the connecting arm 511 and the shielding part 513 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 511 and the shielding part 513 may be separate structures, that is, the connecting arm 511 and the shielding part 513 are two different structures. The connecting arm 511 and the shielding part 513 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.

[0086] Please see Figure 2 and Figure 5In some embodiments, the shielding member 51 further includes a supporting portion 515, which is disposed on the side opposite to the shielding member 513 and the connector 53, and the supporting portion 515 is connected to the connector 53.

[0087] Specifically, in some embodiments, the abutment portion 515 may protrude from the blocking portion 513 toward the connector 53, and when the cleaning device 100 is assembled, the abutment portion 515 can abut against the connector 53. Thus, when the connector 53 moves relative to the roller brush housing 10 in the opposite direction (A1 / A2) along the first direction (A1 / A2), the connector 53 can apply force to the blocking portion 51 through the abutment portion 515, thereby causing the blocking portion 51 to switch from a first blocking position to a second blocking position. Furthermore, the abutment portion 515 facilitates the installation and positioning of the blocking portion 51 and the connector 53, thereby improving the assembly efficiency of the cleaning device 100.

[0088] Please combine Figure 1 In some embodiments, the blocking assembly 50 further includes a second elastic member 505 disposed between the blocking member 51 and the roller brush housing 10, the second elastic member 505 being used to provide a force that moves the blocking member 51 toward the first blocking position.

[0089] Specifically, in some embodiments, when the connector 53 moves in the opposite direction (A2) of the first direction (A1 / A2), the connector 53 applies a force to the blocking member 51, causing the blocking member 51 to move relative to the brush housing 10 towards the second blocking position. In this case, the second elastic member 505 generates an elastic force. When the connector 53 moves in the forward direction (A1) of the first direction (A1 / A2), the connector 53 does not apply a force to the blocking member 51. In this case, the elastic force generated by the second elastic member 505 can cause the blocking member 51 to move towards the first blocking position. Thus, the provision of the second elastic member 505 facilitates the movement of the blocking member 51 relative to the brush housing 10 to switch between the first blocking position and the second blocking position, reducing the power consumption of the drive member 21 during the movement of the blocking member 51. That is, when the blocking member 51 moves relative to the brush housing 10 towards the first blocking position, the drive member 21 can be used without driving, thereby increasing the battery life of the cleaning robot 1000.

[0090] It should be noted that in some embodiments, the second elastic element 505 may be a tension spring or a torsion spring, etc. For example, when the second elastic element 505 is a torsion spring, the second elastic element 505 is disposed between the connecting arm 511 and the brush housing 10. Wherein, when the connecting member 53 moves in the opposite direction A2 along the first direction (A1 / A2), the torsion spring is compressed to generate an elastic force; when the connecting member 53 moves in the forward direction A1 along the first direction (A1 / A2), the elastic force generated by the torsion spring can cause the blocking member 51 to move toward the first blocking position.

[0091] In one example, the second elastic element 505 includes one such element, in which case the second elastic element 505 can be connected to the blocking element 51 in a direction perpendicular to both the forward direction X and the height direction Z of the cleaning robot 1000 (e.g., Figure 2 The shield 51 is positioned at the middle of the direction C), thus ensuring the stability of the movement of the shield 51 relative to the brush housing 10. In another example, the second elastic member 505 includes two members, which can be disposed at opposite ends of the shield 51 in a direction perpendicular to both the forward direction X and the height direction Z of the cleaning robot 1000.

[0092] Please see Figure 1 and Figure 2 In some embodiments, the transmission component 23 includes a second output end. The lifting assembly 60 includes a connecting shaft 61 and a lifting member 63. The connecting shaft 61 is fixedly mounted on the roller brush housing 10. The lifting member 63 is rotatably sleeved on the connecting shaft 61 and can engage or disengage with the second output end of the transmission component 23. When the second output end of the transmission component 23 engages with the lifting member 63, the lifting member 63 rotates about the connecting shaft 61 in the positive direction B2 of the second direction (B1 / B2) to switch from a first lifting position to a second lifting position. When the second output end of the transmission component 23 disengages from the lifting member 63, the lifting member 63 rotates about the connecting shaft 61 in the opposite direction B1 of the second direction (B1 / B2) to switch from the second lifting position to the first lifting position. When the lifting member 63 is in the first lifting position, the distance between the roller brush assembly 40 and the surface to be cleaned is less than the distance between the roller brush assembly 40 and the surface to be cleaned when the lifting member 63 is in the second lifting position.

[0093] In some embodiments, the lifting assembly 60 further includes a restoring member 64, which is connected to the connecting shaft 61 and the lifting member 63. When the second output end of the transmission component 23 is disengaged from the lifting member 63, the restoring member 64 provides a force to the lifting member 63, causing the lifting member 63 to rotate about the connecting shaft 61 in the opposite direction (B1 / B2) B1 to switch from the second lifting position to the first lifting position. That is, the force provided by the restoring member 64 can restore the lifting member 63 to its original position without requiring the driving assembly 20 to output power, thus saving power. For example, the restoring member 64 can be a torsion spring, which can be sleeved on the connecting shaft 61 and abut against the lifting member 63. When the lifting member 63 moves from the first lifting position to the second lifting position, the torsion spring deforms under force. When the second output end of the transmission component 23 is disengaged from the lifting member 63, the torsion spring returns to its original shape to provide a force to the lifting member 63, causing it to return from the second lifting position to the first lifting position.

[0094] It should be noted that, in some embodiments, the second output end of the transmission component 23 can be a portion of the transmission component 23 that can cooperate with the lifting assembly 60 and transmit the driving force of the driving component 21 to the lifting component 63. For example, when the second output end of the transmission component 23 cooperates with the lifting component 63, the lifting component 63 rotates about the connecting shaft 61 in the positive direction B2 of the second direction (B1 / B2) to switch from the first lifting position to the second lifting position. The lifting component 63 applies a force to the bracket 210 of the machine body 200 (e.g., pressing the bracket 210 downwards towards the surface to be cleaned), causing the roller brush housing 10 to rotate about the rotating shaft 220 (the rotating arm 16 of the roller brush housing 10 is connected to the machine body 200 via the rotating shaft 220), thereby lifting the roller brush housing 10 upwards and driving the roller brush assembly 40 upwards. It is understandable that when the second output end of the transmission component 23 is engaged with the lifting component 60, the roller brush housing 10 can be raised or lowered. Since the roller brush component 40 is connected to the roller brush housing 10, it will be raised or lowered along with it.

[0095] Specifically, in some embodiments, when the output end of the drive member 21 rotates in the second rotation direction, the driving force of the drive member 21 can be transmitted to the lifting member 63 through the second output end of the transmission member 23, and drive the lifting member 63 to rotate around the connecting shaft 61 to switch between the first lifting position and the second lifting position, and drive the roller brush assembly 40 to rise and fall relative to the body 200. This facilitates the cleaning robot 1000 to overcome obstacles and improves its passability. On the other hand, it helps the cleaning robot 1000 adapt to different cleaning environments and improves its cleaning effect.

[0096] Please see Figures 1 to 3In some embodiments, the transmission component 23 includes a third output end, which is connected to the roller brush 41. The roller brush 41 rotates relative to the roller brush cavity shell 14 under the drive of the drive member 21. It should be noted that, in some embodiments, the third output end of the transmission component 23 can be a portion of the transmission component 23 that can cooperate with the roller brush 41 and transmit the driving force of the drive member 21 to the roller brush 41.

[0097] Specifically, in some embodiments, when the output end of the drive member 21 rotates in the first rotation direction, the driving force of the drive member 21 can be transmitted to the roller brush 41 through the third output end of the transmission member 23, so as to drive the roller brush 41 to rotate relative to the roller brush cavity shell 14 in the first direction, thereby achieving cleaning of the surface to be cleaned. When the output end of the drive member 21 rotates in the second rotation direction, the driving force of the drive member 21 can be transmitted to the roller brush 41 through the third output end of the transmission member 23, so as to drive the roller brush 41 to rotate relative to the roller brush cavity shell 14 in the second direction. When the output end of the drive member 21 rotates in the second rotation direction, the driving force of the drive member 21 can be transmitted to the roller brush 41, the shielding member 51, or the lifting member 63 through the transmission member 23 to adjust the position of the shielding member 51 or the lifting member 63. The process is relatively short, and the rotation of the roller brush 41 is also short, resulting in limited cleaning of the surface to be cleaned. Therefore, after adjusting the position of the shielding member 51 or the lifting member 63, the output end of the drive member 21 can be controlled to rotate in the first rotation direction to drive only the roller brush 41 to rotate and perform the cleaning work. At this time, the shielding member 51 or the lifting member 63 will not change.

[0098] Please see Figure 6 In some embodiments, the cleaning device 100 further includes a detection component 80 disposed on the roller brush housing 10 and the transmission component 23. The detection component 80 is used to detect the position of the moving part 2352 in the transmission component 23 relative to the roller brush housing 10.

[0099] The detection component 80 enables the cleaning device 100 to obtain the current position of the moving part 2352 and obtain the position of the shielding component 50 and the lifting component 60 relative to the roller brush housing 10 based on the current position of the moving part 2352. This facilitates the cleaning device 100 to adjust the position of the moving part 2352 in a timely and accurate manner, thereby adjusting the position of the shielding component 50 and the lifting component 60 and ensuring the stability and reliability of the cleaning device 100.

[0100] Furthermore, in some embodiments, the detection component 80 includes a first detection element 81 and a second detection element 83, one of which is disposed on the brush housing 10 and the other is disposed on the moving element 2352. The first detection element 81 and the second detection element 83 cooperate to detect the position of the moving element 2352 relative to the brush housing 10.

[0101] Specifically, in some embodiments, one of the first detection element 81 and the second detection element 83 may be an electromagnetic sensor (e.g., a Hall sensor), a photoelectric sensor (e.g., a laser sensor), or an ultrasonic sensor, and the other of the first detection element 81 and the second detection element 83 may be a component that can cooperate with an electromagnetic sensor (e.g., a Hall sensor), a photoelectric sensor (e.g., a laser sensor), or an ultrasonic sensor. Thus, the first detection element 81 and the second detection element 83 can cooperate to jointly detect the movement position of the moving element 2352 relative to the brush housing 10.

[0102] For example, one of the first detection element 81 and the second detection element 83 is a light emitter and the other is a light receiver. The light emitter is used to emit light (laser or infrared light, etc.) and the light receiver is used to receive light and indicate the position of the moving element 2352 relative to the brush housing 10 according to the received light.

[0103] In other embodiments, the cleaning device 100 further includes a detection component 80 disposed in the brush housing 10 and at least one of the blocking component and the lifting component, the detection component 80 being used to detect the position of the blocking member 51 of the blocking component 50 relative to the brush housing 10 and / or the position of the lifting member 63 of the lifting component 60 relative to the brush housing 10.

[0104] The detection component 80 enables the cleaning device 100 to directly obtain the position of the shielding component 51 and / or the lifting component 63 relative to the roller brush housing 10, which is beneficial for the cleaning device 100 to adjust the position of the shielding component 50 and the lifting component 60, and ensures the stability and reliability of the cleaning device 100 in operation.

[0105] Furthermore, in some embodiments, the detection component 80 includes a first detection element 81 and a second detection element 83. One of the first detection element 81 and the second detection element 83 is disposed in the brush housing 10, and the other is disposed in the blocking component 50 and / or the lifting component 60. The first detection element 81 and the second detection element 83 cooperate to detect the position of the connecting member 53 relative to the brush housing 10 and / or the position of the lifting member 63 relative to the brush housing 10. It is understood that the first detection element 81 and the second detection element 83 in this embodiment are substantially the same as those in the above embodiments, and will not be described again here.

[0106] Please see Figure 1 , Figure 12 or Figure 15 In some embodiments, the cleaning device 100 may further include a protective cover 91, which is disposed on the roller brush housing 10 and together with the roller brush housing 10 forms an installation space. At least a portion of the transmission component 23 is located within the installation space. Thus, the protective cover 91 can prevent external water, dust, sand, or other impurities from contacting the transmission component 23, thereby preventing impurities from damaging the transmission component 23 and preventing the risk of impurities causing jamming in the operation of the transmission component 23, ensuring the stability and reliability of the cleaning device 100.

[0107] It should be noted that, in some embodiments, the protective cover 91 and the roller brush housing 10 can be connected together by a detachable connection or a non-detachable connection. The detachable connection includes, but is not limited to, snap-fit ​​connection or threaded connection; the non-detachable connection includes, but is not limited to, bonding or welding.

[0108] Please see Figure 1 , Figure 2 , Figure 3 and Figure 19 In some embodiments, the cleaning device 100 further includes a fan connected to the receiving cavity 18. When the fan draws air, a negative pressure state can be formed in the receiving cavity 18. At this time, there is a certain pressure difference between the receiving cavity 18 and the external atmospheric pressure, thereby giving the receiving cavity 18 a certain suction force to achieve the suction of garbage on the surface to be cleaned. It can be understood that when the blocking component 50 moves to reduce the opening size of the suction port 11, the receiving cavity 18 can more effectively achieve a high vacuum, thereby effectively improving the cleaning effect of the cleaning device 100.

[0109] However, if there is a large gap between the shielding component 50 and the cover 12, even when the shielding component 50 moves to reduce the opening size of the suction port 11, the receiving cavity 18 can still communicate with the outside through the gap between the shielding component 50 and the cover 12, which will make it difficult for the receiving cavity 18 to achieve a high vacuum and affect the cleaning effect of the cleaning device 100.

[0110] Please combine Figure 19In some embodiments of this disclosure, the cleaning device 100 further includes a first seal 93 connected to the shielding assembly 50. During at least a portion of the time period when the shielding assembly 50 reduces the opening size of the suction inlet 11, the first seal 93 seals the gap between the shielding assembly 50 and the cover 12. Thus, the first seal 93 ensures the sealing effect of the receiving cavity 18 after the shielding assembly 50 reduces the opening size of the suction inlet 11, enabling the receiving cavity 18 to achieve a high vacuum, thereby improving the cleaning effect of the cleaning device 100. It should be noted that in some embodiments, the material of the first seal 93 includes, but is not limited to, rubber, silicone, and foam.

[0111] Specifically, in some embodiments, the first sealing member 93 may be disposed on the blocking portion 513 of the blocking member 51 and cooperate with the first side 103 of the cover 12. When the blocking assembly 50 reduces the opening size of the suction port 11 and the fan draws air, the first sealing member 93 can swing toward the cover 12 and abut against the cover 12 to seal the gap between the blocking assembly 50 and the cover 12.

[0112] Please see Figure 1 and Figure 19 In some embodiments, the body 200 is provided with a mounting housing 230 for accommodating at least a portion of the roller brush housing 10. Specifically, in some embodiments, the mounting housing 230 is provided with a mounting space 250, which is recessed from the side of the mounting housing 230 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 250. The mounting space 250 reduces the space occupied by the cleaning device 100 and the body 200, thereby facilitating the miniaturization of the cleaning robot; it also facilitates the mounting and positioning of the cleaning device 100 on the body 200, thereby improving the assembly efficiency of the cleaning device 100.

[0113] Usually, please combine Figure 2 and Figure 3 When the cleaning device 100 is installed on the mounting housing 230, a certain gap needs to be maintained between the two to prevent interference between the shielding component 50 and the mounting housing 230 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 50 and the mounting housing 230, thus affecting the cleaning effect. For example, in one possible scenario, dirt in the gap between the shielding component 50 and the mounting housing 230 can easily fall onto the cleaned surface to be cleaned, affecting the cleaning effect.

[0114] In some embodiments of this disclosure, the cleaning device 100 further includes a second seal 95, which is disposed between the shielding member 51 of the shielding assembly 50 and the mounting housing 230. The second seal 95 seals the gap between the shielding member 51 and the mounting housing 230. Therefore, the second seal 95 prevents external dust and other dirt from entering the gap between the shielding member 51 and the mounting housing 230, thereby ensuring the cleanliness of the cleaning robot and improving its cleaning effect. It should be noted that in some embodiments, the material of the second seal 95 includes, but is not limited to, rubber, silicone, and foam.

[0115] Specific Implementation Method 1 of this Application

[0116] Please see Figure 1 , Figure 2 and Figure 5 In Embodiment 1, the connecting member 53 of the shielding assembly 50 includes a first sub-component 531 and a second sub-component 532. The first sub-component 531 is connected to the shielding member 51. The second sub-component 532 is provided with a matching member 56, which is connected to the first output end of the transmission member 23. The second sub-component 532 is connected to the first sub-component 531. When the connecting member 53 moves along the first direction (A1 / A2), the second sub-component 532 and the first sub-component 531 are either relatively stationary or relatively moving.

[0117] In cases where the shielding member 51 is subjected to an external force (e.g., the force generated when the shielding member 51 collides with an obstacle or a protrusion on the surface to be cleaned during the operation of the cleaning device 100), and the shielding member 51 cannot move relative to the surface to be cleaned to release the external force, the shielding member 51 will be damaged, affecting the service life of the shielding assembly 50 and the normal operation of the cleaning device 100. Therefore, in this embodiment, the second sub-component 532 and the first sub-component 531 can move relative to each other, allowing the shielding member 51 to move away from the surface to be cleaned when subjected to an external force to release the external force, thereby reducing the possibility of damage to the shielding assembly 50, extending the service life of the shielding assembly 50, and ensuring the normal operation of the cleaning device 100. In addition, when the external force on the shielding member 51 disappears, the second sub-component 532 and the first sub-component 531 can move relative to each other to allow the shielding member 51 to return to its previous position.

[0118] In this embodiment, one of the first sub-component 531 and the second sub-component 532 is provided with a protrusion 5301, and the other is provided with an accommodating space 5303. The bottom of the accommodating space 5303 is provided with a groove 5305 extending along a first direction (A1 / A2). The protrusion 5301 extends into the groove 5305 and can move within the groove 5305 along the first direction (A1 / A2). It should be noted that in some embodiments, the quantitative relationship between the protrusion 5301 and the groove 5305 can be one-to-one; or many-to-one, that is, one protrusion 5301 corresponds to one groove 5305; or, multiple protrusions 5301 correspond to one groove 5305.

[0119] The accommodating space 5303 serves two purposes: firstly, it guides the relative movement of the first sub-component 531 and the second sub-component 532, ensuring the stability of their relative movement; secondly, it reduces the space occupied by the first sub-component 531 and the second sub-component 532, which is beneficial for miniaturizing the cleaning device 100; and thirdly, it facilitates the installation and positioning of the first sub-component 531 and the second sub-component 532, thereby improving the assembly efficiency of the connector 53.

[0120] Specifically, in some embodiments, the first sub-component 531 is provided with a protrusion 5301, and the second sub-component 532 is provided with an accommodating space 5303. In this case, when the first sub-component 531 extends into the accommodating space 5303, the protrusion 5301 can extend into the groove 5305. Thus, the cooperation of the protrusion 5301 and the groove 5305 can restrict the direction of relative movement of the first sub-component 531 and the second sub-component 532, that is, restrict the first sub-component 531 and the second sub-component 532 to only be able to move relative to each other along a first direction (A1 / A2).

[0121] In one example, the groove 5305 can be a through groove, meaning that the groove 5305 extends through the bottom of the accommodating space 5303. This allows for quick troubleshooting when the relative movement of the first sub-component 531 and the second sub-component 532 is obstructed. For example, when the first sub-component 531 and the second sub-component 532 cannot move relative to each other, it facilitates observation of whether the protrusion 5301 is stuck in the groove 5305, thus ensuring the stability and reliability of the shielding assembly 50. In another example, the groove 5305 can be a blind groove, meaning that the groove 5305 is recessed from the bottom of the accommodating space 5303 towards the direction away from the center of the accommodating space 5303, but the groove 5305 does not extend through the bottom of the accommodating space 5303. This prevents external water or dust and other impurities from entering the accommodating space 5303 and contaminating the shielding assembly 50, thereby ensuring the cleanliness of the cleaning device 100.

[0122] In this embodiment, in the first direction (A1 / A2), the groove 5305 includes opposing first side surface 5307 and second side surface 5309, with the first side surface 5307 being closer to the mating member 56 than the second side surface 5309. The blocking member 501 also includes a first elastic member 55, which is disposed between the first sub-member 531 and the second sub-member 532. When the connecting member 53 moves in the positive direction A1 of the first direction (A1 / A2), the protrusion 5301 abuts against the first side surface 5307. When the connecting member 53 moves in the opposite direction A2 of the first direction (A1 / A2), the first elastic member 55 keeps the first sub-member 531 and the second sub-member 532 relatively stationary. When the force on the blocking member 51 exceeds a preset force threshold, the first elastic member 55 is compressed, the first sub-member 531 and the second sub-member 532 move relative to each other, and the protrusion 5301 moves between the first side surface 5307 and the second side surface 5309.

[0123] Specifically, in some embodiments, when the connector 53 moves in the forward direction A1 along the first direction (A1 / A2), the protrusion 5301 abuts against the first side surface 5307. In this case, the connector 53 can drive the shielding member 51 to move away from the surface to be cleaned, for example, driving the shielding member 51 to switch from the second shielding position to the first shielding position. When the connector 53 moves in the reverse direction A2 along the first direction (A1 / A2), the elastic force of the first elastic member 55 can keep the first sub-member 531 and the second sub-member 532 relatively stationary. In this case, the protrusion 5301 still abuts against the first side surface 5307, and the connector 53 can drive the shielding member 51 to move closer to the surface to be cleaned, for example, driving the shielding member 51 to switch from the first shielding position to the second shielding position. Furthermore, when the force exerted on the shielding member 51 exceeds the preset force threshold, that is, when the external force exerted on the shielding member 51 exceeds the preset force threshold, the first elastic member 55 is compressed. In this case, the first sub-member 531 and the second sub-member 532 move relative to each other, that is, the shielding member 51 moves relative to the connecting member 53. This can buffer the force exerted on the shielding member 51, prevent the shielding member 51 from rigidly colliding with obstacles or protrusions on the surface to be cleaned, and ensure the normal operation of the cleaning device 100.

[0124] For example, when the first elastic member 55 includes a compression spring, the opposite ends of the compression spring are connected to the first sub-member 531 and the second sub-member 532, respectively. When the protrusion 5301 abuts against the first side 5307, the compression spring can be in a compressed state with a certain compression margin, or it can be in an extended state. The second sub-member 532 can push the first sub-member 531 to move through the compression spring, thereby causing the blocking member 51 to move relative to the brush housing 10. When the force on the blocking member 51 exceeds a preset force threshold, the compression spring is compressed to cause the first sub-member 531 and the second sub-member 532 to move relative to each other, and can absorb the force on the blocking member 51. When the force on the blocking member 51 disappears, the elastic force generated by the compression of the spring can restore the blocking member 51 to its previous position.

[0125] It is understandable that when the protrusion 5301 abuts against the first side 5307, the blocking member 51 is not subjected to any force (the force refers to any force other than the force applied to the blocking member 51 by the first elastic member 55); or, the force on the blocking member 51 is less than a preset force threshold.

[0126] In some embodiments, a protruding structure may be provided on the sidewalls opposite to the first sub-component 531 and the second sub-component 532; or, a protruding structure may be provided on the sidewalls opposite to the first sub-component 531. Therefore, compared to the direct contact between the first sub-component 531 and the second sub-component 532, the protruding structure reduces the friction between the first sub-component 531 and the second sub-component 532, resulting in smoother relative movement between them. The protruding structure in this embodiment is essentially the same as the first protruding structure 537 in the aforementioned embodiments, and will not be described in detail here.

[0127] Please see Figure 1 and Figure 2 In this embodiment, the lifting assembly 60 further includes a sliding member 65, which is slidably mounted on the roller brush housing 10 and rotatably connected to the lifting member 63. The second output end of the transmission component 23 engages or disengages with the lifting member 63 via the sliding member 65. Specifically, when the second output end of the transmission component 23 engages with the lifting member 63 via the sliding member 65, the driving force of the drive member 21 can be transmitted to the lifting member 63, causing the lifting member 63 to move between a first lifting position and a second lifting position, thereby driving the cleaning device 100 to rise and fall relative to the body 200. When the second output end of the transmission component 23 disengages from the lifting member 63, the driving force of the drive member 21 is not transmitted to the lifting member 63, and at this time, the lifting member 63 can be located in the first lifting position.

[0128] Furthermore, in some embodiments, the slider 65 includes a sliding portion 651 and a sliding protrusion 653, the sliding protrusion 653 being able to engage with the second output end of the transmission component 23. The roller brush housing 10 is provided with a guide groove 17, which is used to accommodate at least a portion of the sliding portion 651 and to guide the sliding portion 651 to move relative to the roller brush housing 10.

[0129] Specifically, in some embodiments, the guide groove 17 is recessed from the outer wall of the roller brush housing 10 toward the center of the roller brush housing 10, and at least a portion of the sliding part 651 is disposed in the guide groove 17. Thus, the guide groove 17 restricts the movement direction of the sliding part 651 relative to the roller brush housing 10, preventing the sliding part 651 from shifting during movement and causing the lifting assembly 60 to fail to drive the cleaning device 100 to rise and fall relative to the body 200, thereby ensuring the stability and reliability of the cleaning device 100's operation.

[0130] Please see Figure 2 In some embodiments, on the third direction C, the guide groove 17 includes opposing first guide sidewalls 171 and second guide sidewalls 173, and the sliding part 651 is slidably engaged with both the first guide sidewalls 171 and the second guide sidewalls 173. The third direction C is perpendicular to the forward direction X of the cleaning robot 1000. This reduces the friction between the sliding part 651 and the guide groove 17, thereby preventing excessive friction between the sliding part 65 and the guide groove 17 from preventing the sliding part 65 from moving relative to the brush housing 10, thus ensuring the normal operation of the lifting assembly 60. On the other hand, it reduces the power consumption required by the drive assembly 20 to drive the sliding part 65, increasing the battery life of the cleaning robot 1000.

[0131] Furthermore, in some embodiments, a protrusion structure may be provided on the sliding portion 651 or the first guide sidewall 171, with the protrusion structure located between the sliding portion 651 and the first guide sidewall 171; and / or, a protrusion structure may be provided on the sliding portion 651 or the second guide sidewall 173, with the protrusion structure located between the sliding portion 651 and the second guide sidewall 173. Thus, compared to the direct contact between the sliding portion 651 and the sidewalls of the guide groove 17 (including the first guide sidewall 171 and the second guide sidewall 173), the protrusion structure reduces the friction between the sliding portion 651 and the sidewalls of the guide groove 17, making the movement of the sliding portion 651 in the guide groove 17 smoother. The structure of the protrusion structure in this embodiment is basically the same as the structure of the first protruding structure 537 in the above embodiments, and will not be described in detail here.

[0132] Please see Figure 2In some embodiments, the transmission component 23 includes a first transmission unit 231, a second transmission unit 233, a third transmission unit 235, and a clutch unit 237. The input end of the first transmission unit 231 is connected to the output end of the drive member 21. The input end of the second transmission unit 233 is connected to the first output end of the first transmission unit 231, and the output end of the second transmission unit 233 (i.e., the third output end of the transmission component 23) is connected to the roller brush assembly 40. The output end of the third transmission unit 235 (i.e., the first and second output ends of the transmission component 23) is connected to the shielding assembly 50 or the lifting assembly 60. One end of the clutch unit 237 is connected to the second output end of the first transmission unit 231, and the other end of the clutch unit 237 is connected to the input end of the third transmission unit 235. The clutch unit 237 is used to connect or disconnect the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235.

[0133] Specifically, in some embodiments, when the output end of the drive member 21 rotates in the first rotation direction, the driving force of the drive member 21 can be transmitted to the first transmission unit 231, and then sequentially transmitted to the roller brush assembly 40 through the first output end of the first transmission unit 231 and the second transmission unit 233, so as to drive the roller brush assembly 40 to move; when the output end of the drive member 21 rotates in the second rotation direction, the driving force of the drive member 21 can be transmitted to the first transmission unit 231, and then sequentially transmitted to the roller brush assembly 40, the blocking assembly 50 or the lifting assembly 60 through the second output end of the first transmission unit 231, the clutch unit 237 and the third transmission unit 235, so as to drive the roller brush assembly 40, the blocking assembly 50 or the lifting assembly 60 to move. Understandably, when the output end of the drive unit 21 rotates in the first rotation direction, the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is disconnected; when the output end of the drive unit 21 rotates in the second rotation direction, the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is connected. This prevents the lifting component 60 and the blocking component 50 from moving during the movement of the roller brush assembly 40, thus affecting the cleaning of the surface to be cleaned by the roller brush assembly 40, thereby ensuring the normal operation of the cleaning device 100.

[0134] Further, in some embodiments, the first transmission unit 231 includes a first rotating shaft 2311 rotatably mounted on the brush housing 10, and the third transmission unit 235 includes a second rotating shaft 2351 rotatably mounted on the brush housing 10. The clutch unit 237 includes a first transmission member 2371, a second transmission member 2373, and a third transmission member 2375. The first transmission member 2371 is fixedly mounted on the first rotating shaft 2311. The second transmission member 2373 is slidably mounted on the second rotating shaft 2351, and engages with the first transmission member 2371. The third transmission member 2375 is fixedly mounted on the second rotating shaft 2351. When the first rotating shaft 2311 rotates, the first transmission member 2371 rotates and drives the second transmission member 2373 to rotate, thereby switching the second transmission member 2373 between a first sliding position and a second sliding position. When the second transmission member 2373 is in the first sliding position, the second transmission member 2373 and the third transmission member 2375 are disengaged, and the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is disconnected; when the second transmission member 2373 is in the second sliding position, the second transmission member 2373 and the third transmission member 2375 are engaged, and the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is connected.

[0135] It should be noted that, in some embodiments, the first transmission member 2371 and the second transmission member 2373 can both be helical gears, and the third transmission member 2375 can be a ratchet. Along the extending direction of the second rotation shaft 2351, the second transmission member 2373 has teeth on its end face facing the third transmission member 2375, and the third transmission member 2375 also has teeth on its end face facing the second transmission member 2373. Specifically, when the second transmission member 2373 is in the first sliding position, the teeth on the end face of the second transmission member 2373 are spaced apart from the third transmission member 2375, and the second transmission member 2373 cannot drive the third transmission member 2375 to rotate. Thus, the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is disconnected. When the second transmission member 2373 is in the second sliding position, the teeth on the end face of the second transmission member 2373 can mesh with the teeth on the ratchet, and the second transmission member 2373 can drive the third transmission member 2375 to rotate. Thus, the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is connected.

[0136] Furthermore, in some embodiments, the output end of the drive member 21 rotates in a first rotation direction to move the second transmission member 2373 to or in a first sliding position. The output end of the drive member 21 rotates in a second rotation direction to move the second transmission member 2373 to or in a second rotation position, wherein the first rotation direction is opposite to the second rotation direction.

[0137] Specifically, in some embodiments, when the output end of the drive member 21 rotates in the first rotation direction, the first rotating shaft 2311 rotates relative to the brush housing 10 in the first rotation direction and drives the first transmission member 2371 to rotate in the first rotation direction. The rotation of the first transmission member 2371 can drive the second transmission member 2373 to rotate relative to the second rotating shaft 2351, and drive the second transmission member 2373 to move relative to the second rotating shaft 2351 towards the first sliding position, for example, driving the second transmission member 2373 to move from the second sliding position to the first sliding position. In this case, the power transmission between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is... The power transmission path is disconnected. When the output end of the drive unit 21 rotates in the second rotation direction, the first rotating shaft 2311 rotates relative to the brush housing 10 in the second rotation direction and drives the first transmission member 2371 to rotate in the second rotation direction. The rotation of the first transmission member 2371 can drive the second transmission member 2373 to rotate relative to the second rotating shaft 2351, and drive the second transmission member 2373 to move relative to the second rotating shaft 2351 towards the second sliding position. For example, it can drive the second transmission member 2373 to move from the first sliding position to the second sliding position. In this case, the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is connected. It should be noted that in some embodiments, the first rotation direction and the second rotation direction are opposite.

[0138] Please see Figure 2 and Figure 6 In some embodiments, the third transmission unit 235 includes a moving member 2352 connected to the clutch unit 237. When the driving force of the drive member 21 is transmitted to the moving member 2352, the moving member 2352 moves relative to the roller brush housing 10 to drive the shielding assembly 50 or the lifting assembly 60 to operate.

[0139] Furthermore, in some embodiments, when the driving force of the drive member 21 is transmitted to the moving member 2352, the moving member 2352 moves relative to the roller brush housing 10 along a fourth direction (Y1 / Y2) to drive the shielding assembly 50 or the lifting assembly 60 to operate. For example, the fourth direction (Y1 / Y2) is perpendicular to the forward direction X of the cleaning robot 1000.

[0140] Specifically, in some embodiments, the third transmission unit 235 may further include a gear linkage unit 2350, one end of which is connected to the clutch unit 237, and the other end is connected to the moving member 2352. When the second transmission member 2373 and the third transmission member 2375 are engaged, so that the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is connected, the gear linkage unit 2350 can convert the rotational driving force of the third transmission member 2375 into a kinetic driving force, thereby driving the moving member 2352 to move relative to the brush housing 10 along the fourth direction (Y1 / Y2), thereby driving the blocking assembly 50 or the lifting assembly 60. It should be noted that in some embodiments, the fourth direction (Y1 / Y2) may be the same as the third direction C.

[0141] In some embodiments, the moving member 2352 includes a moving body 2354 and a protrusion 2356, the protrusion 2356 extending protruding from the moving body 2354. When the clutch unit 237 transmits the driving force of the drive member 21 to the moving member 2352, the moving member 2352 moves relative to the brush housing 10 in the fourth direction (Y1 / Y2) to drive the lifting assembly 60 to operate. It should be noted that in some embodiments, the protrusion 2356 is the second output end of the transmission member 23.

[0142] Specifically, please combine Figure 13 In some embodiments, the protrusion 2356 includes a bump, which has a first surface 23561 and a second surface 23563 facing away from each other in the fourth direction (Y1 / Y2). The first surface 23561 is the side of the bump that corresponds to and engages with the sliding protrusion 653. For example, the bump is trapezoidal, and the first surface 23561 and the second surface 23563 are the two sides of the trapezoid. The first surface 23561 is inclined, and the distance between the first surface 23561 and the moving body 2354 gradually increases in the direction from the first surface 23561 to the second surface 23563. Therefore, compared to when the first surface 23561 is not inclined, the power consumption required for the drive member 21 to drive the moving member 2352 to move the sliding protrusion 653 along the protrusion 2356 is smaller in this embodiment. In addition, the inclined setting of the first surface 23561 can prevent jamming when the sliding protrusion 653 abuts against the protrusion 2356, which could lead to failures such as burnout of the drive component 21, thereby improving the safety of the drive component 20 and extending its service life.

[0143] In some embodiments, the moving body 2354 and the protrusion 2356 may be an integral structure, that is, the moving body 2354 and the protrusion 2356 may be integrally molded to form a single structure, thereby improving the bonding strength between the moving body 2354 and the protrusion 2356 and preventing the protrusion 2356 from falling off the moving body 2354 when the moving component 2352 engages with the lifting assembly 60, thereby improving the stability and reliability of the cleaning device 100. In other embodiments, the moving body 2354 and the protrusion 2356 may be separate structures, that is, the moving body 2354 and the protrusion 2356 are two different structures. The moving body 2354 and the protrusion 2356 may be connected together using a non-removable connection method or a detachable connection method. 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.

[0144] In some embodiments, when the protrusion 2356 engages with the lifting assembly 60, the lifting assembly 60 is in a second lifted position and the roller brush assembly 40 is at a first height relative to the body 200. When the protrusion 2356 is disengaged from the lifting assembly 60, the lifting assembly 60 is in the first lifted position and the roller brush assembly 40 is at a second height relative to the body 200, with the first height being greater than the second height.

[0145] Specifically, in some embodiments, the engagement between the protrusion 2356 and the lifting component 60 can be such that the sliding protrusion 653 is supported on the protrusion 2356 and moves on the protrusion 2356; the disengagement between the protrusion 2356 and the lifting component 60 can be such that the sliding protrusion 653 is not supported on the protrusion 2356. When the moving part 2352 moves along the fourth direction (Y1 / Y2) to engage (abut) the protrusion 2356 with the sliding protrusion 653, the sliding protrusion 653 can move relative to the brush housing 10 along the first surface 23561 toward the top of the protrusion 2356 (the side of the protrusion 2356 away from the moving body 2354) until the sliding protrusion 653 moves to the top of the protrusion 2356. At this time, the lifting assembly 60 is in the second lifting position, and the brush assembly 40 is at the first height relative to the body 200. When the moving part 2352 moves along the fourth direction (Y1 / Y2) to disengage the protrusion 2356 from the sliding protrusion 653, the sliding protrusion 653 disengages from the first surface 23561. At this time, the lifting assembly 60 is in the first lifting position, and the brush assembly 40 is at the second height relative to the body 200. Therefore, the drive component 20 can drive the lifting component 60 to move, so that the roller brush component 40 can switch between a first height and a second height, thereby improving the obstacle-crossing ability of the cleaning device 100 and ensuring the normal operation of the cleaning device 100.

[0146] Understandably, when the roller brush assembly 40 is at a first height relative to the body 200, the blocking member 51 of the blocking assembly 50 is in the first blocking position. At this time, the cleaning device 100 can overcome obstacles to ensure the normal operation of the cleaning device 100. When the roller brush assembly 40 is at a second height relative to the body 200, the blocking member 51 of the blocking assembly 50 is in the second blocking position. At this time, the opening of the suction port 11 is smaller, the suction force of the receiving cavity 18 is larger, and the cleaning device 100 can clean the target area. When the roller brush assembly 40 is at a second height relative to the body 200, the blocking member 51 of the blocking assembly 50 is in the first blocking position. At this time, the opening of the suction port 11 is larger, the suction force of the receiving cavity 18 is smaller, and the cleaning device 100 can clean non-target areas.

[0147] In some embodiments, one of the moving part 2352 and the roller brush housing 10 is provided with a guide part 101, and the other of the moving part 2352 and the roller brush housing 10 is provided with a mating part 2357. The guide part 101 and the mating part 2357 cooperate to guide the moving part 2352 to move along the fourth direction (Y1 / Y2).

[0148] Specifically, see Figure 6 In some embodiments, one of the guide portion 101 and the mating portion 2357 may be a protrusion, and the other may be a groove. When the moving member 2352 is disposed on the roller brush housing 10, the protrusion can engage with the groove to guide the moving member 2352 to move relative to the roller brush housing 10 in the fourth direction (Y1 / Y2). Furthermore, the engagement of the protrusion with the groove can also limit the travel distance of the moving member 2352 relative to the roller brush housing 10, preventing the moving member 2352 from being unrestricted in the fourth direction (Y1 / Y2) when the drive assembly 20 program malfunctions, thus preventing the moving member 2352 from colliding and being damaged with the roller brush housing 10 or other structures on the roller brush housing 10, thereby ensuring the stability and reliability of the cleaning device 100 operation.

[0149] Please see Figure 2 and Figure 6 In some embodiments, the moving member 2352 is provided with a moving groove 2353, and the blocking assembly 50 includes a matching member 56 that mates with the moving groove 2353. The matching member 56 is housed in the moving groove 2353. The moving member 2352 moves relative to the brush housing 10 in a fourth direction (Y1 / Y2) so that the blocking assembly 50 moves relative to the brush housing 10 in a first direction (A1 / A2) via the matching member 56. It should be noted that in some embodiments, the moving groove 2353 is the first output end of the transmission member 23.

[0150] Specifically, in some embodiments, when the cleaning device 100 is assembled, the mating member 56 is located in the moving groove 2353 and can move within the moving groove 2353 to allow the shielding assembly 50 to move relative to the roller brush housing 10 along a first direction (A1 / A2). In one example, the moving member 2352 includes a first side and a second side facing away from each other, with the first side of the moving member 2352 opposite to the roller brush housing 10. The moving groove 2353 can be a through groove, that is, the moving groove 2353 passes through the first side and the second side of the moving member 2352. Thus, when the movement of the mating member 56 in the moving groove 2353 is obstructed, the cause of the fault can be quickly identified. For example, when the mating member 56 cannot move, it is easy to observe whether the mating member 56 is stuck in the moving groove 2353, thereby ensuring the stability and reliability of the cleaning device 100.

[0151] In another example, the moving groove 2353 can be a blind groove, that is, the moving groove 2353 is recessed from the first side of the moving member 2352 toward the second side of the moving member 2352, but the moving groove 2353 does not penetrate through the second side of the moving member 2352. This prevents external water or dust and other impurities from entering and accumulating in the moving groove 2353, thereby preventing the cleaning device 100 from being contaminated and preventing impurities from affecting the movement of the mating member 56, ensuring the normal operation of the shielding assembly 50. In yet another example, the moving groove 2353 can be a blind groove, that is, the moving groove 2353 is recessed from the second side of the moving member 2352 toward the first side of the moving member 2352, but the moving groove 2353 does not penetrate through the first side of the moving member 2352.

[0152] Please combine Figure 2 and Figure 6 In some embodiments, the movable groove 2353 includes an elongated groove. The elongated groove allows the shielding assembly 50 to move relative to the roller brush housing 10 along a first direction (A1 / A2) to change the opening size of the suction port 11, thereby improving the applicability of the cleaning device 100 and enhancing its cleaning effect. It should be noted that in some embodiments, the cross-sectional shape of the elongated groove may include, but is not limited to, a racetrack shape or a rectangle.

[0153] In other embodiments, the movable slot 2353 includes a first sub-slot 23531, a second sub-slot 23533, and a third sub-slot 23535. The first sub-slot 23531 extends along a fourth direction (Y1 / Y2). The second sub-slot 23533 extends along the fourth direction (Y1 / Y2) and is offset from the first sub-slot 23531 in a first direction (A1 / A2). The third sub-slot 23535 is located between the first sub-slot 23531 and the second sub-slot 23533 and connects the first sub-slot 23531 and the second sub-slot 23533. The angle between the inner surfaces of the first sub-slot 23531 and the third sub-slot 23535 is an obtuse angle, and the angle between the inner surfaces of the second sub-slot 23533 and the third sub-slot 23535 is also an obtuse angle. For example, the movable slot 2353 is Z-shaped. It should be noted that, in the height direction of the cleaning device 100, the distance between the first sub-slot 23531 and the surface to be cleaned is greater than the distance between the second sub-slot 23533 and the surface to be cleaned.

[0154] In this embodiment, the matching component 56 reciprocates more smoothly between the first sub-slot 23531, the second sub-slot 23533, and the third sub-slot 23535, reducing the possibility of the matching component 56 getting stuck in the moving slot 2353, thereby ensuring the normal operation of the shielding component 50. It should be noted that the settings can be adjusted according to actual needs; for example, the angle between the inner surface of the first sub-slot 23531 and the inner surface of the third sub-slot 23535 can be less than or equal to 90°, and the angle between the inner surface of the second sub-slot 23533 and the inner surface of the third sub-slot 23535 can be less than or equal to 90°.

[0155] In one example, the mating part 56 can be a protrusion. In another example, the mating part 56 can be a pulley. When the mating part 56 is a pulley, the outer periphery of the mating part 56 is a convex arc surface. The convex arc surface contacts the moving groove 2353, and the contact area is small, which can reduce the friction of the mating part 56 in the moving groove 2353, making the movement of the mating part 56 smoother.

[0156] It is understood that in some embodiments, the inner surfaces of the first sub-slot 23531 and the third sub-slot 23535 are smoothly connected, and the inner surfaces of the second sub-slot 23533 and the third sub-slot 23535 are smoothly connected. This can further reduce the movement resistance of the matching member 56 in the moving slot 2353 and reduce the power consumption required for the drive member 21 to drive the blocking assembly 50 to move along the first direction (A1 / A2) through the moving member 2352.

[0157] In some embodiments, the included angle between the inner surface of the first sub-groove 23531 and the inner surface of the third sub-groove 23535 can be in the range of (90°, 180°), that is, the included angle between the inner surface of the first sub-groove 23531 and the inner surface of the third sub-groove 23535 can be any value between 90° and 180°, such as 95°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170° and 180°. 75°; the angle between the inner surface of the second sub-slot 23533 and the inner surface of the third sub-slot 23535 can be (90°, 180°), that is, the angle between the inner surface of the second sub-slot 23533 and the inner surface of the third sub-slot 23535 can be any value between 90° and 180°, such as 95°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170° and 175°.

[0158] In this embodiment, the moving slot 2353 includes a first sub-slot 23531, a second sub-slot 23533, and a third sub-slot 23535 as an example for explanation.

[0159] Please combine Figures 9 to 11 In some embodiments, when the matching member 56 is in a first matching position in the moving groove 2353, the moving member 2352 is in a first moving position, and the blocking member 51 of the blocking assembly 50 is in a first blocking position relative to the brush housing 10. When the matching member 56 is in a second matching position in the moving groove 2353, the moving member 2352 is in a second moving position, and the blocking member 51 of the blocking assembly 50 is in a first blocking position relative to the brush housing 10. When the matching member 56 is in a third matching position in the moving groove 2353, the moving member 2352 is in a third moving position, and the blocking member 51 of the blocking assembly 50 is in a second blocking position relative to the brush housing 10. The opening size of the suction inlet 11 when the blocking member 51 is in the first blocking position is larger than the opening size of the suction inlet 11 when the blocking member 51 is in the second blocking position.

[0160] Specifically, in some embodiments, when the matching member 56 is in the first matching position in the moving groove 2353, the matching member 56 is located at one end of the first sub-groove 23531 near the third sub-groove 23535. In this case, the blocking member 51 is in the first blocking position relative to the roller brush housing 10, and the cleaning device 100 can clean the non-target area. Figure 9(As shown); When the matching member 56 is in the second matching position in the moving slot 2353, the matching member 56 is located at the end of the first sub-slot 23531 away from the third sub-slot 23535. In this case, the blocking member 51 is in the first blocking position relative to the brush housing 10, the sliding protrusion 653 matches the protrusion 2356, the lifting assembly 60 is in the second lifting position, and the brush assembly 40 is at the first height relative to the body 200. The brush assembly 40 can be lifted to perform obstacle crossing, mopping, or entering and exiting the base station, etc. Figure 10 (As shown); When the matching member 56 is in the third matching position in the moving groove 2353, the matching member 56 is located in the second sub-groove 23533. In this case, the blocking member 51 is in the second blocking position relative to the roller brush housing 10, and the cleaning device 100 can clean the target area. Figure 11 As shown). Thus, when the moving part 2352 reciprocates along the fourth direction (Y1 / Y2), the blocking part 51 can switch between a first blocking position and a second blocking position relative to the roller brush housing 10, thereby changing the opening size of the suction port 11. This allows the cleaning device 100 to be adapted to different working scenarios, improving the cleaning robot 100 (as shown). Figure 20 (As shown) Applicability.

[0161] In some embodiments, where one of the first detection element 81 and the second detection element 83 is a light emitter and the other is a light receiver, the light emitter may include a first emitter, a second emitter, and a third emitter, and the light receiver may include a first receiver, a second receiver, and a third receiver. Specifically, when the moving element 2352 is in a first moving position, the first emitter and the first receiver correspond; when the moving element 2352 is in a second moving position, the second emitter and the second receiver correspond; and when the moving element 2352 is in a third moving position, the third emitter and the third receiver correspond.

[0162] Compared to Figure 8 The embodiment shown, Figure 2 In the embodiment shown, the clutch unit 237 is positioned closer to the first transmission unit 231, making the transmission component 23 more compact, simpler, and with a shorter transmission distance, which facilitates its disassembly, assembly, and maintenance. At the same time, it is convenient to cover the entire transmission component 23 with a protective shell to prevent dust, moisture, etc. from entering and damaging its service life.

[0163] Specific Implementation Method Two of this Application

[0164] Please see Figure 12The shielding component 50 in the second embodiment also includes a limiting member 503, which is disposed between the connector 53 and the roller brush housing 10. The limiting member 503 provides resistance to the reverse movement of the connector 53 relative to the roller brush housing 10 in the first direction (A1 / A2) along the first direction (A1 / A2) in the opposite direction A2.

[0165] Specifically, in some embodiments, when the driving force of the driving member 21 is transmitted to the connecting member 53 through the transmission component, and the connecting member 53 moves in the opposite direction (A1 / A2) A2, the limiting member 503 can exert a force on the connecting member 53, the direction of which is approximately the same as the positive direction (A1) of the first direction (A1 / A2). When the driving force of the driving member 21 disappears, the force generated by the limiting member 503 can cause the connecting member 53 to move in the positive direction (A1 / A2) A1 of the first direction to return to its previous position. Thus, the limiting member 503 facilitates the movement of the connecting member 53 relative to the brush housing 10 in the first direction (A1 / A2), reducing the power consumption of the driving member 21 during the movement of the connecting member 53. That is, when the connecting member 53 moves in the positive direction (A1 / A2) A1 of the first direction (A1 / A2) relative to the brush housing 10, no driving force from the driving member 21 is required. Furthermore, the limiting member 503 can prevent the connecting member 53 from falling off the roller brush housing 10, thereby ensuring the stability and reliability of the shielding assembly 50 in operation.

[0166] In some embodiments, the roller brush housing 10 is provided with two mounting slots 13. The connector 53 includes a connecting body 533 and a connecting protrusion 534. The connecting body 533 is movably mounted on the roller brush housing 10, and the connecting protrusion 534 extends protruding from the connecting body 533. The limiting member 503 includes a limiting body 5031 and two opposing connecting ends 5033. The two connecting ends 5033 are respectively installed in the two mounting slots 13, and the limiting body 5031 is sleeved on the connecting protrusion 534.

[0167] Specifically, in some embodiments, the connecting body 533 includes a first side and a second side facing away from each other, with the first side of the connecting body 533 opposite to the brush housing 10. A connecting protrusion 534 extends from the second side of the connecting body 533 in a direction away from the first side of the connecting body 533. The limiting member 503 may be a torsion spring. When the connecting member 53 moves in the opposite direction (A1 / A2) along the first direction (A1 / A2) in the opposite direction (A2), the torsion spring generates an elastic restoring force, the direction of which is approximately the same as the positive direction (A1 / A2) of the first direction (A1 / A2). When the driving force of the driving member 21 disappears, the elastic restoring force generated by the limiting member 503 enables the connecting member 53 to move along the positive direction (A1 / A2) along the first direction (A1 / A2) in the positive direction (A1 / A2) to return to its previous position.

[0168] In some embodiments, the connecting end 5033 may be installed in the mounting groove 13 using a detachable or non-detachable connection method. 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.

[0169] It is understood that the specific structure of the lifting component 60 in this embodiment is exactly the same as that of the lifting component 60 in Embodiment 1, and will not be described again here; the specific structure of the driving component 20 in this embodiment is roughly the same as that of the driving component 20 in Embodiment 1. The difference between the driving component 20 in this embodiment and the driving component 20 in Embodiment 1 is that:

[0170] Please see Figure 2 and Figure 13 In this embodiment, the moving component 2352 includes a moving body 2354 and a linkage part 2355, which is connected to the moving body 2354. The blocking component 50 includes a matching part 56 that cooperates with the linkage part 2355. During the movement of the moving component 2352 along the fourth direction (Y1 / Y2), the linkage part 2355 causes the blocking component 50 to move relative to the brush housing 10 through the matching part 56.

[0171] Specifically, in some embodiments, during the movement of the moving member 2352 along the fourth direction (Y1 / Y2), the linkage 2355 and the moving body 2354 can move together along the fourth direction (Y1 / Y2), and the linkage 2355 can abut against the mating member 56, and drive the blocking assembly 50 to move relative to the roller brush housing 10 along the first direction (A1 / A2) through the mating member 56. For example, during the movement of the moving member 2352 in the forward Y1 direction of the fourth direction (Y1 / Y2), the linkage 2355 can drive the blocking assembly 50 to move relative to the roller brush housing 10 in the reverse A2 direction of the first direction (A1 / A2); during the movement of the moving member 2352 in the reverse Y2 direction of the fourth direction (Y1 / Y2), the blocking assembly 50 can move relative to the roller brush housing 10 in the reverse A2 direction of the first direction (A1 / A2); during the movement of the moving member 2352 in the reverse Y2 direction of the fourth direction (Y1 / Y2), the blocking assembly 50 can move relative to the second elastic member 505 (… Figure 1 Under the influence of (as shown), it moves along the positive direction A1 in the first direction (A1 / A2).

[0172] Furthermore, please combine Figure 14In some embodiments, the linkage 2355 includes a linkage sub-part 23551 and an elastic element 23553. The linkage sub-part 23551 is movably connected to the motion body 2354. The elastic element 23553 is disposed between the motion body 2354 and the linkage sub-part 23551. When the motion body 2354 moves along the fourth direction (Y1 / Y2), the linkage sub-part 23551 moves along the fourth direction (Y1 / Y2) with the motion body 2354. When the linkage sub-part 23551 engages with the mating member 56, the elastic element 23553 provides a restoring force. When the linkage sub-part 23551 disengages from the mating member 56, the restoring force is used to reset the linkage sub-part 23551.

[0173] Specifically, in some embodiments, when the moving member 2352 moves along the fourth direction (Y1 / Y2) and the linkage sub-part 23551 engages (abuts) with the matching member 56, the linkage sub-part 23551 can drive the matching member 56 to move along the first direction (A1 / A2) so that the blocking assembly 50 moves along the first direction (A1 / A2). In this case, the elastic element 23553 generates a restoring force, which can return the linkage sub-part 23551 to its previous position when the linkage sub-part 23551 and the matching member 56 are disengaged.

[0174] In cases where the shielding member 51 is subjected to an external force (e.g., the force generated when the shielding member 51 collides with an obstacle or a protrusion on the surface to be cleaned during the operation of the cleaning device 100), and the shielding member 51 cannot move relative to the surface to be cleaned to release the external force, the shielding member 51 will be damaged, affecting the service life of the shielding assembly 50 and the normal operation of the cleaning device 100. Therefore, in this embodiment, the linkage sub-part 23551 and the moving body 2354 can move relative to each other, thereby enabling the shielding member 51 to move away from the surface to be cleaned when subjected to an external force to release the external force, thus preventing damage to the shielding assembly 50 and ensuring the normal operation of the cleaning device 100. In addition, when the force on the shielding member 51 disappears, the shielding member 51 can return to its position before movement.

[0175] Specifically, when the shielding member 51 moves away from the surface to be cleaned, the elastic element 23553 deforms so that the linkage sub-part 23551 can move relative to the moving body 2354 in the opposite direction (Y1 / Y2) Y2, thereby allowing the shielding member 51 to move away from the surface to be cleaned to release the external force, prevent damage to the shielding assembly 50, and ensure the normal operation of the cleaning device 100; when the force on the shielding member 51 disappears, the shielding member 51 can return to its position before movement, and at the same time, the restoring force generated by the elastic element 23553 can cause the linkage sub-part 23551 to move relative to the moving body 2354 in the positive direction (Y1 / Y2) Y1, so that the linkage sub-part 23551 is reset.

[0176] In some embodiments, the linkage sub-part 23551 includes a first side and a second side facing away from each other, with the first side of the linkage sub-part 23551 correspondingly engaging with the mating member 56. The elastic element 23553 may be a compression spring, with its opposite ends connected to the second side of the linkage sub-part 23551 and the moving body 2354, respectively. When the linkage sub-part 23551 engages with the mating member 56, the compression spring is in a compressed state with a certain compression margin. The elastic force generated by the compression spring allows the linkage sub-part 23551 to drive the mating member 56 to move along a first direction (A1 / A2). When the force on the blocking member 51 exceeds a preset force threshold, the compression spring is compressed, causing the linkage sub-part 23551 to move relative to the moving body 2354 and absorbing the force on the blocking member 51. When the force on the blocking member 51 disappears, the elastic force generated by the compression spring allows the blocking member 51 to return to its previous position.

[0177] In some embodiments, when the blocking member 51 is in the second blocking position, the linkage sub-part 23551 engages with the matching member 56. The linkage sub-part 23551 includes a mating surface 23555 for engaging with the matching member 56, and the mating surface 23555 is inclined relative to the fourth direction (Y1 / Y2). It should be noted that in some embodiments, the mating surface 23555 may be the first side of the linkage sub-part 23551 in the above embodiments.

[0178] Specifically, in some embodiments, the distance between the mating surface 23555 and the surface to be cleaned gradually decreases in the direction from the first side to the second side of the linkage sub-part 23551. Therefore, the inclined arrangement of the mating surface 23555 prevents jamming when it mates with the matching part 56, which could lead to malfunctions such as burnout of the drive component 21. This improves the safety of the drive assembly 20 and extends its service life.

[0179] Specific Implementation Method 3 of this Disclosure

[0180] Please see Figure 15 The specific structure of the shielding component 50 and the cooperation relationship between the shielding component 50 and the roller brush housing 10 in Embodiment 3 are basically the same as those in Embodiment 1, and will not be described again here.

[0181] Please see Figure 15 and Figure 16 In this embodiment, the lifting member 63 includes a sleeve portion 631 and a hook portion 633. The sleeve portion 631 is rotatably sleeved on the connecting shaft 61. The hook portion 633 is connected to the sleeve portion 631 and extends from the sleeve portion 631 by bending. The hook portion 633 is used to engage the bracket 210 in the machine body 200. Figure 2 (as shown) A force is applied to cause the support 210 to exert a reaction force on the cleaning device 100 relative to the lifting of the support 210.

[0182] In some embodiments, the sleeve portion 631 and the hook portion 633 may be an integral structure, that is, the sleeve portion 631 and the hook portion 633 may be integrally molded to form a single structure, thereby improving the bonding strength between the sleeve portion 631 and the hook portion 633 and preventing breakage of the sleeve portion 631 and the hook portion 633 when the lifting member 63 is engaged with the bracket 210, thereby improving the stability and reliability of the cleaning device 100. In other embodiments, the sleeve portion 631 and the hook portion 633 may be separate structures, that is, the sleeve portion 631 and the hook portion 633 are two different structures. The sleeve portion 631 and the hook portion 633 may 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.

[0183] Furthermore, in some embodiments, the socket portion 631 is provided with a socket protrusion 6311, which can cooperate with the second output end of the transmission component 23.

[0184] Specifically, in some embodiments, when the driving force of the drive member 21 is transmitted to the sleeve protrusion 6311 through the second output end of the transmission member 23, the sleeve protrusion 6311 can drive the sleeve portion 631 to rotate relative to the connecting shaft 61, so that the hook portion 633 applies a force to the bracket 210 in the body 200, thereby causing the bracket 210 to apply a reaction force relative to the lifting of the bracket 210 to the cleaning device 100 through the lifting member 63.

[0185] Please combine Figure 17In some embodiments, the transmission component 23 includes a first transmission unit 231, a second transmission unit 233, a third transmission unit 235, and a clutch unit 237. The input end of the first transmission unit 231 is connected to the output end of the drive member 21. The input end of the second transmission unit 233 is connected to the first output end of the first transmission unit 231, and the output end of the second transmission unit 233 (i.e., the third output end of the transmission component 23) is connected to the roller brush assembly 40. The output ends of the third transmission unit 235 (i.e., the first and second output ends of the transmission component 23) are connected to the shielding assembly 50 and the lifting assembly 60. One end of the clutch unit 237 is connected to the second output end of the first transmission unit 231, and the other end of the clutch unit 237 is connected to the input end of the third transmission unit 235. The clutch unit 237 is used to connect or disconnect the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235.

[0186] Specifically, in some embodiments, when the output end of the drive member 21 rotates in the first rotation direction, the driving force of the drive member 21 can be transmitted to the first transmission unit 231, and then sequentially transmitted to the roller brush assembly 40 through the first output end of the first transmission unit 231 and the second transmission unit 233, so as to drive the roller brush assembly 40 to move; when the output end of the drive member 21 rotates in the second rotation direction, the driving force of the drive member 21 can be transmitted to the first transmission unit 231, and then sequentially transmitted to the roller brush assembly 40, the blocking assembly 50 or the lifting assembly 60 through the second output end of the first transmission unit 231, the clutch unit 237 and the third transmission unit 235, so as to drive the roller brush assembly 40, the blocking assembly 50 or the lifting assembly 60 to move. Understandably, when the output end of the drive unit 21 rotates in the first rotation direction, the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is disconnected; when the output end of the drive unit 21 rotates in the second rotation direction, the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 is connected. This prevents the lifting component 60 and the blocking component 50 from moving during the movement of the roller brush assembly 40, thus affecting the cleaning of the surface to be cleaned by the roller brush assembly 40, thereby ensuring the normal operation of the cleaning device 100.

[0187] In some embodiments, the clutch unit 237 includes a one-way clutch 2377, which includes a first sub-part and a second sub-part that are rotatably connected. The first sub-part is connected to the second output end of the first transmission unit 231, and the second sub-part is connected to the input end of the third transmission unit 235. The first sub-part and the second sub-part cooperate to connect or disconnect the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235.

[0188] Specifically, in some embodiments, the one-way clutch 2377 may include a one-way bearing, with one of the first sub-parts and the second sub-parts being the inner ring of the one-way bearing, and the other being the outer ring of the one-way bearing. The first sub-part can only rotate freely relative to the second sub-part in either a clockwise or counterclockwise direction. For example, the first sub-part can rotate freely relative to the second sub-part in a clockwise direction and lock in a counterclockwise direction; or, the first sub-part can rotate freely relative to the second sub-part in a counterclockwise direction and lock in a clockwise direction. Thus, when the first sub-part is connected to the second output end of the first transmission unit 231, and the second sub-part is connected to the input end of the third transmission unit 235, the first and second sub-parts can control the connection or disconnection of the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235 according to the rotation direction of the second output end of the first transmission unit 231.

[0189] Furthermore, in some embodiments, the output end of the drive member 21 rotates in a first rotation direction to disconnect the transmission between the first sub-part and the second sub-part, thus disconnecting the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235. The output end of the drive member 21 rotates in a second rotation direction to connect the transmission between the first sub-part and the second sub-part, thus connecting the power transmission path between the second output end of the first transmission unit 231 and the input end of the third transmission unit 235. The first rotation direction is opposite to the second rotation direction.

[0190] Please see Figures 15 to 17 In some embodiments, when the driving force of the drive member 21 is transmitted to the moving member 2352, the moving member 2352 rotates relative to the roller brush housing 10 to drive the shielding assembly 50 or the lifting assembly 60 to operate.

[0191] Furthermore, in some embodiments, the moving component 2352 includes a main transmission unit 23580, a first transmission unit 2358, and a second transmission unit 2359. The main transmission unit 23580 is connected to the clutch unit 237. When the driving force of the driving component 21 is transmitted to the main transmission unit 23580, the main transmission unit 23580 drives the first transmission unit 2358 and the second transmission unit 2359 to rotate together relative to the brush housing 10. The first transmission unit 2358 drives the lifting assembly 60 to operate; the second transmission unit 2359 drives the blocking assembly 50 to operate. Exemplarily, the main transmission unit 23580, the first transmission unit 2358, and the second transmission unit 2359 can be coaxially connected, that is, the main transmission unit 23580, the first transmission unit 2358, and the second transmission unit 2359 are connected on the same shaft.

[0192] Furthermore, in some embodiments, the first transmission section 2358 is provided with a protrusion 23581. When the driving force of the driving member 21 is transmitted to the first transmission section 2358, the first transmission section 2358 rotates relative to the brush housing 10, causing the protrusion 23581 to drive the lifting assembly 60 to move. The second transmission section 2359 is provided with a connecting portion 23591, which is eccentrically disposed relative to the second transmission section 2359. When the second transmission section 2359 rotates relative to the brush housing 10 together with the first transmission section 2358, the connecting portion 23591 drives the blocking assembly 50 to operate.

[0193] Specifically, in some embodiments, the first transmission part 2358 may include a first main body part 23583, which may be fixedly disposed on the second rotating shaft 2351. A protrusion 23581 extends from the outer peripheral wall of the first main body part 23583 in a direction away from the central axis of the first main body part 23583. For example, the cross-sectional shape of the first transmission part 2358 may be designed as a teardrop shape. The second transmission part 2359 includes a second main body part 23593, which may be fixedly disposed on the second rotating shaft 2351. A connecting part 23591 extends from the second main body part 23593 in a direction away from the first main body part 23583. The central axes of the first main body part 23583 and the second main body part 23593 may coincide. It should be noted that in some embodiments, the cross-sectional shape of the protrusion 23581 may be approximately triangular.

[0194] In some embodiments, when the protrusion 23581 engages with the lifting assembly 60, the lifting assembly 60 can be moved to or located in a second lifting position, and the roller brush assembly 40 is at a first height relative to the body 200. When the protrusion 23581 disengages from the lifting assembly 60, the lifting assembly 60 can be moved to or located in the first lifting position, and the roller brush assembly 40 is at a second height relative to the body 200, with the first height being greater than the second height.

[0195] Specifically, in some embodiments, the engagement of the protrusion 23581 with the lifting component 60 can be such that the sleeve protrusion 6311 abuts against the protrusion 23581; the disengagement of the protrusion 23581 from the lifting component 60 can be such that the sleeve protrusion 6311 does not abut against the protrusion 23581. Specifically, when the moving component 2352 rotates relative to the roller brush housing 10 to engage the protrusion 23581 with the sleeve protrusion 6311, the sleeve protrusion 6311 can drive the sleeve portion 631 and the hook portion 633 to rotate around the connecting shaft 61, so that the lifting component 60 is in the second lifted position and the roller brush assembly 40 is at the first height relative to the body 200. When the moving component 2352 rotates relative to the roller brush housing 10 to disengage the protrusion 23581 from the sleeve protrusion 6311, the sleeve portion 631 and the hook portion 633 can rotate in the opposite direction around the connecting shaft 61, so that the lifting component 60 is in the first lifted position and the roller brush assembly 40 is at the second height relative to the body 200. Thus, the drive component 20 can drive the lifting component 60 to move, so that the roller brush assembly 40 can switch between the first height and the second height, thereby improving the obstacle-crossing ability of the cleaning device 100 and ensuring the normal operation of the cleaning device 100.

[0196] In some embodiments, when the connecting portion 23591 rotates relative to the roller brush housing 10 to a first position, the blocking member 51 of the blocking assembly 50 is in a first blocking position relative to the roller brush housing 10. When the connecting portion 23591 rotates relative to the roller brush housing 10 to a second position, the blocking member 51 of the blocking assembly 50 is in a second blocking position relative to the roller brush housing 10. When the blocking member 51 is in the first blocking position, the opening size of the suction inlet 11 is larger than when the blocking member 51 is in the second blocking position. Therefore, when the connecting portion 23591 rotates relative to the roller brush housing 10, the blocking member 51 can switch between the first blocking position and the second blocking position relative to the roller brush housing 10, thereby switching the opening size of the suction inlet 11. This allows the cleaning device 100 to be adapted to different working scenarios, improving the cleaning robot 1000 (…). Figure 20 (As shown) Applicability.

[0197] In some embodiments, when the roller brush assembly 40 is at a first height relative to the body 200, the blocking member 51 of the blocking assembly 50 is in a first blocking position. At this time, the cleaning device 100 can cross obstacles to ensure the normal operation of the cleaning device 100. When the roller brush assembly 40 is at a second height relative to the body 200, the blocking member 51 of the blocking assembly 50 is in a second blocking position. At this time, the opening of the suction port 11 is smaller, the suction force of the receiving cavity 18 is larger, and the cleaning device 100 can clean the target area. When the roller brush assembly 40 is at a second height relative to the body 200, the blocking member 51 of the blocking assembly 50 is in a first blocking position. At this time, the opening of the suction port 11 is larger, the suction force of the receiving cavity 18 is smaller, and the cleaning device 100 can clean non-target areas.

[0198] Please combine Figure 18 In some embodiments, the cleaning device 100 further includes a functional component 2360. When the driving force of the drive member 21 is transmitted to the main transmission unit 23580, the main transmission unit 23580 drives the first transmission unit 2358, the second transmission unit 2359, and the functional component 2360 to rotate together relative to the roller brush housing 10. Exemplarily, the main transmission unit 23580, the first transmission unit 2358, the second transmission unit 2359, and the functional component 2360 can be coaxially connected, that is, the main transmission unit 23580, the first transmission unit 2358, the second transmission unit 2359, and the functional component 2360 are connected on the same shaft. The functional component 2360 can perform functions different from those of the roller brush assembly 40, the shielding assembly 50, and the lifting assembly 60. Exemplarily, when the functional component 2360 moves, it can drive the roller brush assembly 40 to rise and fall relative to the surface to be cleaned. For example, the functional component 2360 lowers the roller brush assembly 40 by pressing down the roller brush housing 10. When the functional component 2360 releases the roller brush housing 10, the roller brush housing 10 drives the roller brush assembly 40 to return to its original state, that is, to rise back to its original position.

[0199] Please see Figure 1 , Figure 3 This disclosure provides a cleaning robot 1000, which includes a body 200 and a cleaning device 100 as described in any of the above embodiments. The cleaning device 100 is disposed on the body 200 and is used to clean the surface to be cleaned.

[0200] In the cleaning robot 1000 of this embodiment, the cleaning device 100 includes a roller brush assembly 40, a shielding assembly 50, and a lifting assembly 60. The drive assembly 20 drives the roller brush assembly 40 to rotate to clean the surface to be cleaned, drives the shielding assembly 50 to move to change the opening size of the suction inlet 11, and drives the lifting assembly 60 to move the roller brush housing 10, thereby causing the roller brush assembly 40 to rise and fall relative to the robot body 200. Therefore, compared to related technologies, the cleaning device 100 can not only clean the surface to be cleaned, but also perform other functions using the roller brush assembly 40, shielding assembly 50, and lifting assembly 60, thereby improving the applicability of the cleaning robot 1000, meeting user needs, and improving cleaning effectiveness, such as deep cleaning of carpets, obstacle crossing, entering and exiting base stations, or roller brush lifting during mopping. Furthermore, by using a single drive assembly, the above-mentioned cleaning functions for different needs can be achieved, saving costs and reducing the installation space of components, making the overall structure of the cleaning robot compact and miniaturized.

[0201] It is understood that the specific structure of the cleaning robot 1000 in this embodiment is exactly the same as that of the cleaning robot 1000 in the above embodiments, and will not be described again here.

[0202] Please see Figure 1 , Figure 3 and Figure 21 This disclosure provides a cleaning system 4000, which includes a cleaning robot 1000 and a base station 3000 as described above. The base station 3000 is used in conjunction with the cleaning robot 1000 and includes a docking position for accommodating the cleaning robot 1000. It is understood that in some embodiments, when the cleaning robot 1000 is located in its docking position, the base station 3000 can perform maintenance on the cleaning robot 1000, including but not limited to charging, dust collection, cleaning of cleaning 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; 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, etc.); 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 and discharges it to the outside. The above maintenance types are merely illustrative descriptions and are not intended to limit this disclosure.

[0203] In the cleaning system 4000 of this embodiment, the cleaning device 100 includes a roller brush assembly 40, a shielding assembly 50, and a lifting assembly 60. The driving assembly 20 is used to drive the roller brush assembly 40 to rotate to clean the surface to be cleaned, drive the shielding assembly 50 to move to change the opening size of the suction port 11, and drive the lifting assembly 60 to move to drive the roller brush housing 10 to move, thereby causing the roller brush assembly 40 to rise and fall relative to the body 200. Thus, compared with related technologies, the cleaning device 100 can not only clean the surface to be cleaned, but also use the roller brush assembly 40, the shielding assembly 50, and the lifting assembly 60 to perform other functions, thereby improving the applicability of the cleaning robot 1000, meeting the user's needs, and improving the cleaning effect.

[0204] 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 placed at rest on a relatively flat surface to be cleaned, the first side does not contact the surface, while the second side does (e.g., the first side is tilted relative to the second side, the second side rests on the surface to be cleaned, and the first side is suspended above the surface); as another example, when the cleaning robot is placed at rest on a relatively flat non-target area, the shielding component does not contact the non-target area (e.g., the shielding component is suspended above the non-target area); as yet another example, when the cleaning robot is placed at rest on a relatively flat target area, the shielding component contacts the target area (e.g., at least a portion of the shielding component contacts the target area).
