DETAILED DESCRIPTION

[0028] Further embodiments of the present disclosure are described below with reference to the accompanying drawings. The same or similar components have the same or similar reference numbers throughout the drawings and the detailed description. In addition, the embodiments of the present disclosure described below with reference to the accompanying drawings are exemplary and are for the purpose of explaining the embodiments of the present disclosure, and should not be understood as limiting the present disclosure.

[0029] A cleaning robot is a device for automatically cleaning a surface to be cleaned such as a carpet, a table top, a wall, a glass, a door, or a floor. The cleaning robot is generally used for cleaning a room in a house, cleaning a large place, and the like. In general, the cleaning robot includes a cleaning device including a cleaning assembly (e.g., a roller brush assembly) that cleans the surface to be cleaned. However, the cleaning device can simply clean the surface to be cleaned, and thus the cleaning robot can have poor applicability and can not satisfy a user's demand. To solve the problem of poor applicability of the cleaning robot, the present disclosure provides a cleaning device 100 (shown in Figure 1 , a cleaning robot 1000 (shown in Figure 9 ), and a cleaning system 4000 (shown in Figure 10 ).

[0030] Referring to Figures 1 to 3 , in conjunction with Figure 9 , the present disclosure provides a cleaning device 100 for a cleaning robot 1000. The cleaning robot 1000 cleans a surface to be cleaned by the cleaning device 100 when performing a cleaning task. The cleaning device 100 includes a roller brush housing 10, a driving assembly 20, a roller brush assembly 40, a shielding assembly 50, a lifting assembly 60, and a pressing assembly 70. The roller brush housing 10 is disposed on a body 200 of the cleaning robot 1000 and has a suction inlet 11 for allowing the surface to be cleaned to enter the roller brush housing 10. The driving assembly 20 is disposed on the roller brush housing 10 or the body 200. The roller brush assembly 40 is at least partially disposed in the roller brush housing 10, and the roller brush assembly 40 is connected to the driving assembly 20. The shielding assembly 50 is connected to the driving assembly 20. The lifting assembly 60 is connected to the driving assembly 20 and the roller brush housing 10. The pressing assembly 70 is connected to the driving assembly 20 and the roller brush housing 10. The driving assembly 20 is configured to drive the roller brush assembly 40 to rotate to clean the surface to be cleaned, to drive the shielding assembly 50 to move to change an opening size of the suction inlet 11, and to drive the lifting assembly 60 or the pressing assembly 70 to move to drive the roller brush housing 10 to move, thereby driving the roller brush assembly 40 to move up and down relative to the body 200.

[0031] It should be noted that in some embodiments, the cleaning robot 1000 is an intelligent device capable of realizing functions such as sweeping, dusting, and mopping. The cleaning robot 1000 includes but is not limited to a sweeping robot, a mopping robot, a sweeping and mopping integrated robot, an intelligent robot, and a mobile robot, etc. The material of the machine body 200 can be a metal material and / or a non-metal material. The metal material includes but is not limited to aluminum, iron, steel, or aluminum alloy, etc. The non-metal material includes but is not limited to plastic, etc. In one example, the machine body 200 can be made of metal material and non-metal material together, so that the structural strength of the machine body 200 is higher, preventing the machine body 200 from being damaged by collision during the working process of the cleaning robot 1000, and improving the stability and reliability of the working of the cleaning robot 1000. In another example, the machine body 200 can be made of non-metal material, for example, the machine body 200 can be made of plastic material, so that the weight of the machine body 200 is lighter, thereby facilitating the lightness of the cleaning robot 1000.

[0032] The cleaning device 100 is a device capable of realizing the sweeping or mopping function of the cleaning robot 1000. 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 ground in a building. In another example, the surface to be cleaned can also be the surface of other objects that need to be cleaned, such as a wall, a bed, a window, etc.

[0033] The material of the roller brush housing 10 can be a metal material and / or a non-metal material. The metal material includes but is not limited to aluminum, iron, steel, or aluminum alloy, etc. The non-metal material includes but is not limited to plastic, etc. Please refer to the description of the material of the machine body 200 for more details. Figure 5 In some embodiments of the present 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 advancing direction X of the cleaning robot 1000, one end of the roller brush housing 10 close to the front end of the machine body 200 is spaced apart from (not in contact with) the surface to be cleaned, and one end of the roller brush housing 10 close to the rear end of the machine body 200 is in contact with the surface to be cleaned. That is, in the advancing direction X of the cleaning robot 1000, one end of the suction port 11 close to the front end of the machine body 200 is not in contact with the surface to be cleaned, and one end of the suction port 11 close to the rear end of the machine body 200 is in contact with the surface to be cleaned. In this way, it can be ensured that as much garbage as possible can be sucked into the roller brush housing 10 through the suction port 11. Compared with the case that one side of the suction port 11 close to the rear end of the machine body 200 is not in contact with the surface to be cleaned, the cleaning device 100 in this embodiment can sweep large garbage, and is not easy to miss sweeping garbage, thereby improving the cleaning effect of the cleaning device 100.

[0034] Further, in some embodiments, the rolling brush housing 10 comprises a cover 12 covering the suction port 11, the cover 12 comprises a first side 103 and a second side 105, and the first side 103 is closer to the front end of the cleaning robot 1000 than the second side 105. When the cleaning device 100 cleans the surface to be cleaned, the first side 103 does not contact the surface to be cleaned, and the second side 105 contacts the surface to be cleaned. For example, at least a part of the first side 103 can be arranged obliquely relative to the second side 105. In this way, the end of the suction port 11 close to the front end of the body 200 does not contact the surface to be cleaned, and the end of the suction port 11 close to the rear end of the body 200 contacts the surface to be cleaned, as described in the above embodiments.

[0035] It should be noted that the orientations described in the embodiments of the present disclosure are defined when the cleaning robot 1000 is carried on the surface to be cleaned. The "front end" and the "rear end" are relative to the advancing direction X of the cleaning robot 1000. When the cleaning robot 1000 moves forward along the advancing direction X, the front end of the body 200 closest to the advancing direction X is the front end of the body 200, and the rear end of the body 200 closest to the advancing direction X is the rear end of the body 200.

[0036] The driving assembly 20 is a structure for providing power in the cleaning device 100. In some embodiments of the present disclosure, when the driving assembly 20 moves stably, the driving force generated by the driving assembly 20 can act on the rolling brush assembly 40, the shielding assembly 50, the lifting assembly 60, and the pressing assembly 70 to drive the rolling 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 or the pressing assembly 70 to move to drive the rolling brush housing 10 to move, thereby driving the rolling brush assembly 40 to lift relative to the body 200.

[0037] In some embodiments, the rolling brush housing 10 further comprises a rolling brush cavity shell 14 and a cover 12, the rolling brush cavity shell 14 has a containing cavity 18 and a suction port 11 communicating with the containing cavity 18, and the cover 12 is detachably connected to the rolling brush cavity shell 14. The cover 12 can be connected to the rolling brush cavity shell 14 in a detachable connection manner such as a buckle connection or a bolt connection.

[0038] The rolling brush assembly 40 comprises a rolling brush 41 arranged in the accommodation cavity 18 and in contact with the surface to be cleaned through the suction port 11. When the driving force generated by the driving assembly 20 is transmitted to the rolling brush 41, the rolling brush 41 rotates relative to the rolling brush cavity shell 14 under the driving of the driving assembly 20. In this way, the rolling brush 41 can sweep the garbage on the surface to be cleaned, and the garbage can be sucked into the accommodation cavity 18 through the suction port 11 under the action of the suction airflow, thereby realizing the cleaning of the surface to be cleaned. It should be noted that the opening size of the suction port 11 can be: the opening size of the rolling brush shell 10 for allowing the garbage to enter the accommodation cavity 18 during the sweeping of the surface to be cleaned.

[0039] Further, in some embodiments, the rolling brush shell 10 is further provided with a dust suction port 19 in communication with the accommodation cavity 18, and the dust suction port 19 is used for allowing the garbage in the accommodation cavity to move out of the accommodation cavity 18. Specifically, when the garbage enters the accommodation cavity 18, the garbage in the accommodation cavity 18 can move out of the accommodation cavity 18 through the dust suction port 19 under the action of the suction airflow and enter the garbage collection container (for example, a dust box) of the cleaning robot 1000.

[0040] Since the opening size of the suction port 11 will have a certain influence on the vacuum degree suction force between the surface to be cleaned and the accommodation cavity 18, specifically, the larger the opening of the suction port 11, the smaller the suction force of the accommodation 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 accommodation cavity 18; the smaller the opening of the suction port 11, the greater the suction force of the accommodation 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 accommodation cavity 18, that is, when sweeping the garbage on the same surface to be cleaned, the larger the opening size of the suction port 11, the greater the suction force required. Therefore, in some embodiments of the present disclosure, the driving assembly 20 can drive the shielding assembly 50 to move to change the opening size of the suction port 11 to adjust the cleaning efficiency of the accommodation cavity 18 of the cleaning device 1000, so that the cleaning device 100 can adaptively adjust the opening size of the suction port 11 according to different surfaces to be cleaned, ensuring that the garbage on different surfaces to be cleaned can be sucked into the accommodation 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.

[0041] In some embodiments, the surface to be cleaned includes a target area and a non-target area. The target area can refer to an area that needs to be cleaned deeply, such as a carpet area, a floor mat area, a foot mat area, a yoga mat area, a rubber mat area, a straw or bamboo mat area, a dirtier area detected, a user-defined area, etc. The non-target area can refer to an area that does not need to be cleaned deeply, or can be an area other than the target area, such as an area without a carpet, an open floor. For example, the target area is a carpet area, and the non-target area is a non-carpet area. Since the garbage (such as dust or fine impurities, etc.) in the target area is easy to hide in the carpet gap, the opening of the suction port 11 needs to be in a smaller state when cleaning the target area, so as to increase the suction force of the containing cavity 18 and ensure the cleaning effect; and / or when cleaning the target area, the roller brush assembly 40 is lowered relative to the body 200, so as to increase the cleaning intensity of the roller brush assembly 40 on the target area, and when the target area is a carpet area, the roller brush assembly 40 can extend into the carpet fibers to clean, thereby ensuring the cleaning effect; since the non-target area is usually smooth, the opening of the suction port 11 can be in a larger state when cleaning the non-target area, so as to make the suction force of the containing cavity 18 meet the cleaning demand, and the opening of the suction port 11 in a larger state can also ensure that the garbage can enter the containing cavity 18 through the suction port 11, preventing the problem that larger garbage is blocked outside the suction port 11.

[0042] Therefore, in some embodiments of the present disclosure, during at least part of the time period when the cleaning robot 1000 cleans the target area, the driving assembly 20 drives the shielding assembly 50 to move to reduce the opening size of the suction port 11 and / or drives the lower pressing assembly 70 to move to drive the roller brush assembly 40 to lower relative to the body 200, and drives the roller brush assembly 40 to rotate to clean the target area. During at least part of the time period when the cleaning robot 1000 cleans the non-target area, the driving assembly 20 drives the roller brush assembly 40 and / or the wiping member 270 of the cleaning robot 1000 to move to clean the target area, and / or drives the shielding assembly 50 to move to increase the opening size of the suction port 11.

[0043] For the cleaning robot 1000, since the rolling brush assembly 40 of the cleaning device 100 needs to be in contact with the surface to be cleaned when the cleaning device 100 is used to implement the sweeping function, and when the cleaning robot 1000 encounters an obstacle, enters or exits the base station 3000, or the cleaning device 100 is used to implement the mopping function, it is desirable that the rolling brush assembly 40 of the cleaning device 100 is lifted or does not contact the surface to be cleaned, so as to facilitate the cleaning robot 1000 to climb over the obstacle when encountering the obstacle, to climb the slope when entering or exiting the base station 3000, or to prevent the rolling brush assembly 40 from being wet and affecting the cleaning effect when mopping. Therefore, in some embodiments of the present disclosure, during at least part of the time when the cleaning robot 1000 crosses the obstacle or enters or exits the base station 3000 or mops, the driving assembly 20 drives the lifting assembly 60 to move to drive the rolling brush assembly 40 to rise relative to the body 200. For example, in the case that the surface to be cleaned has an obstacle, the driving assembly 20 drives the lifting assembly 60 to move to drive the rolling brush assembly 40 to rise relative to the body 200, which on the one hand facilitates the cleaning robot 1000 to climb over the obstacle, thereby improving the passing performance of the cleaning robot 1000, and on the other hand facilitates the cleaning robot 1000 to adapt to different cleaning environments, thereby improving the cleaning effect of the cleaning robot 1000. It can be understood that in some embodiments, during at least part of the time when the cleaning robot 1000 crosses the obstacle or enters or exits the base station or sweeps, the driving assembly 20 drives the lifting assembly 60 to move to drive the rolling brush assembly 40 to descend relative to the body 200. Thus, the normal cleaning of the rolling brush assembly 40 on the surface to be cleaned can be ensured.

[0044] In the cleaning device 100 of the embodiments of the present disclosure, the cleaning device 100 comprises the rolling brush assembly 40, the shielding assembly 50, the lifting assembly 60 and the pressing assembly 70, and the driving assembly 20 is used to drive the rolling 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 11, and drive the lifting assembly 60 or the pressing assembly 70 to move to drive the rolling brush housing 10 to move, thereby driving the rolling brush assembly 40 to rise or descend relative to the body 200. Thus, compared with the related art, the cleaning device 100 not only can clean the surface to be cleaned, but also can perform other functions by the rolling brush assembly 40, the shielding assembly 50, the lifting assembly 60 and the pressing assembly 70, thereby improving the applicability of the cleaning robot 1000, meeting the use requirements of the user, and improving the cleaning effect.

[0045] The cleaning device 100 will be further explained below in combination with the drawings.

[0046] Please refer to Figures 1 to 3In some embodiments, the driving assembly 20 includes a driving member 21, and the driving assembly 20 drives the rolling brush assembly 40 to rotate for cleaning the surface to be cleaned, drives the shielding assembly 50 to move for changing the opening size of the suction port 11, and drives the lifting assembly 60 or the pressing assembly 70 to move for driving the rolling brush housing 10 to move, thereby driving the rolling brush assembly 40 to move relative to the body 200 (as shown in the figure) to lift or press. Figure 9

[0047] Specifically, in some embodiments, when the driving member 21 is stably operated, the driving member 21 can output a driving force, and the driving force can be transmitted to the rolling brush assembly 40, the shielding assembly 50, the lifting assembly 60 or the pressing assembly 70 to drive the rolling brush assembly 40, the shielding assembly 50, the lifting assembly 60 or the pressing assembly 70 to move. The driving member 21 can be arranged on the rolling brush housing 10 or the body 200. The driving member 21 and the rolling brush housing 10 or the body 200 can be combined together by a detachable connection manner or a non-detachable connection manner, and the non-detachable connection manner includes but is not limited to bonding or welding, etc. The detachable connection manner includes but is not limited to buckle connection or screw connection, etc. It should be noted that, in some embodiments, the driving member 21 can be a driving structure such as a motor or an electric push rod, wherein the motor includes but is not limited to a direct current servo motor, an alternating current servo motor and a stepping motor, etc.

[0048] ​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 or the pressing assembly 70 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. For example, one of the two drive components 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 or the pressing assembly 70 to move to raise the roller brush assembly 40 relative to the body 200; the other of the two drive components 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 or the pressing assembly 70 to move to lower the roller brush assembly 40 relative to the body 200. Alternatively, one of the two drive components 21 can drive the roller brush assembly 40, the shielding assembly 50, the lifting assembly 60, or the pressing assembly 70 to move, while the other can drive the remaining three of the roller brush assembly 40, the shielding assembly 50, the lifting assembly 60, or the pressing assembly 70 to move. For example, one of the two drive components 21 can drive two movements of the roller brush assembly 40, the blocking assembly 50, the lifting assembly 60, and the pressing assembly 70, while the other can drive the remaining two movements of the roller brush assembly 40, the blocking assembly 50, the lifting assembly 60, and the pressing assembly 70.

[0049] In some embodiments, the drive assembly 20 includes only one drive member 21. That is, one drive member 21 can drive the roller brush assembly 40, the shielding assembly 50, the lifting assembly 60, and the pressing assembly 70 to move. Therefore, the movement of the roller brush assembly 40, the shielding assembly 50, the lifting assembly 60, and the pressing assembly 70 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 10 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.

[0050] Please continue reading. Figures 1 to 3Further, in some embodiments, the driving assembly 20 further comprises a transmission component 23. The transmission component 23 is connected with the output end of the driving member 21, and the transmission component 23 is configured to transmit the driving force of the driving member 21 to the rolling brush assembly 40, the shielding assembly 50, the lifting assembly 60 or the pressing assembly 70. Specifically, in some embodiments, when the driving member 21 is in stable operation, the driving member 21 can output the driving force, and the driving force can be transmitted to the rolling brush assembly 40, the shielding assembly 50, the lifting assembly 60 or the pressing assembly 70 through the transmission component 23 to drive the rolling brush assembly 40, the shielding assembly 50, the lifting assembly 60 or the pressing assembly 70 to move.

[0051] In some embodiments, when the output end of the driving member 21 rotates in a first rotation direction, the transmission component 23 transmits the driving force of the driving member 21 to the rolling brush assembly 40. When the output end of the driving member 21 rotates in a second rotation direction, the transmission component 23 transmits the driving force of the driving member 21 to at least the shielding assembly 50, the lifting assembly 60 or the pressing assembly 70, and the first rotation direction and the second rotation direction are opposite. It should be noted that, in some embodiments, when the driving member 21 is a motor, the output end of the driving member 21 is the output shaft of the driving member 21.

[0052] Specifically, in some embodiments, when the output shaft of the driving member 21 rotates in a first rotation direction, the transmission component 23 can transmit the driving force of the driving member 21 to the rolling brush assembly 40 to drive the rolling brush assembly 40 to move to clean the surface to be cleaned, in which case the transmission component 23 does not transmit the driving force of the driving member 21 to the shielding assembly 50, the lifting assembly 60 or the pressing assembly 70, i.e., the shielding assembly 50, the lifting assembly 60 and the pressing assembly 70 remain in a state of stopping working; when the output shaft of the driving member 21 rotates in a second rotation direction, the transmission component 23 can transmit the driving force of the driving member 21 to the shielding assembly 50 to drive the shielding assembly 50 to move to change the opening size of the suction inlet 11; or, the transmission component 23 can transmit the driving force of the driving member 21 to the lifting assembly 60 to drive the lifting assembly 60 to move and drive the rolling brush assembly 40 to ascend or descend relative to the body 200; or, the transmission component 23 can transmit the driving force of the driving member 21 to the pressing assembly 70 to drive the pressing assembly 70 to move and drive the rolling brush assembly 40 to ascend or descend relative to the body 200; or, the transmission component 23 can transmit the driving force of the driving member 21 to the rolling brush assembly 40 to drive the rolling brush assembly 40 to rotate. In this way, the cleaning device 100 can control the rotation direction of the output end of the driving member 21 to control the cleaning device 100 to realize different functions, thereby improving the applicability of the cleaning robot 1000 (as shown). Figure 9

[0053] Please refer to Figure 9 ​In some embodiments, during rotation of the output end of the driving member 21 in a first rotation direction, the roller brush assembly 40 rotates in a first direction, and during rotation of the output end of the driving member 21 in a second rotation direction, the roller brush assembly 40 rotates in a second direction, and the cleaning device 100 comprises at least one of a first state, a second state, a third state, a fourth state and a fifth state, the first direction being opposite to the second direction. In the first state, the driving member 21 drives the shielding assembly 50 to change the opening size of the suction inlet 11; in the second state, the driving member 21 does not drive the shielding member 51 of the shielding assembly 50 to move, does not drive the lifting assembly 60 to move, and does not drive the pressing-down assembly 70 to move; in the third state, the driving member 21 drives the lifting assembly 60 to move to drive the roller brush housing 10 to lift and lower, thereby driving the roller brush assembly 40 to lift and lower relative to the machine body 200; in the fourth state, the driving member 21 drives the pressing-down assembly 70 to move to drive the roller brush housing 10 to lift and lower, thereby driving the roller brush assembly 40 to lift and lower relative to the machine body 200; in the fifth state, the driving member 21 drives the shielding assembly to change the opening size of the suction inlet 11, and drives the pressing-down assembly 70 to move to drive the roller brush housing 10 to lift and lower, thereby driving the roller brush assembly 40 to lift and lower relative to the machine body 200.

[0054] Specifically, the cleaning device 100 is in a first state, the driving member 21 drives the shielding assembly 50 to move to reduce or increase the opening size of the suction port 11; the cleaning device 100 is in a second state, the driving member 21 does not drive the shielding member 51 of the shielding assembly 50 to move, nor does it drive the lifting assembly 60 and the pressing-down assembly 70 to move; the cleaning device 100 is in a third state, the driving member 21 drives the lifting assembly 60 to move to drive the rolling brush assembly 40 to ascend or descend relative to the body 200; the cleaning device 100 is in a fourth state, the driving member 21 drives the pressing-down assembly 70 to move to drive the rolling brush assembly 40 to ascend or descend relative to the body 200; the cleaning device 100 is in a fifth state, the driving member 21 drives the shielding assembly 50 to move to reduce or increase the opening size of the suction port 11, and drives the pressing-down assembly 70 to move to drive the rolling brush assembly 40 to ascend or descend relative to the body 200. Exemplarily, the cleaning robot 1000 includes a deep cleaning mode, a deep cleaning enhanced mode, a normal cleaning mode, a pressing-down mode, and a lifting mode.Specifically, in the process of switching the cleaning robot 1000 from the deep cleaning mode to the normal cleaning mode, the driving member 21 drives the shielding assembly 50 to move to increase the opening size of the suction port 11; in the process of switching the cleaning robot 1000 from the normal cleaning mode to the lifting mode, the driving member 21 drives the lifting assembly 60 to move to drive the rolling brush assembly 40 to ascend relative to the body 200; in the process of switching the cleaning robot 1000 from the lifting mode to the normal cleaning mode, the driving member 21 drives the lifting assembly 60 to move to drive the rolling brush assembly 40 to descend relative to the body 200; in the process of switching the cleaning robot 1000 from the normal cleaning mode to the deep cleaning mode, the driving member 21 drives the shielding assembly 50 to move to decrease the opening size of the suction port 11; in the process of switching the cleaning robot 1000 from the deep cleaning mode to the lifting mode, the driving member 21 drives the shielding assembly 50 to move to increase the opening size of the suction port 11, and drives the lifting assembly 60 to move to drive the rolling brush assembly 40 to ascend relative to the body 200; in the process of switching the cleaning robot 1000 from the lifting mode to the deep cleaning mode, the driving member 21 drives the shielding assembly 50 to move to decrease the opening size of the suction port 11, and drives the lifting assembly 60 to move to drive the rolling brush assembly 40 to descend relative to the body 200; in the process of switching the cleaning robot 1000 from the deep cleaning mode to the deep cleaning enhanced mode, the driving member 21 drives the pressing assembly 70 to move to drive the rolling brush assembly 40 to descend relative to the body 200; in the process of switching the cleaning robot 1000 from the deep cleaning enhanced mode to the deep cleaning mode, the driving member 21 drives the pressing assembly 70 to move to drive the rolling brush assembly 40 to ascend relative to the body 200; in the process of switching the cleaning robot 1000 from the normal cleaning mode to the pressing mode, the driving member 21 drives the pressing assembly 70 to move to drive the rolling brush assembly 40 to descend relative to the body 200; in the process of switching the cleaning robot 1000 from the pressing mode to the normal cleaning mode, the driving member 21 drives the pressing assembly 70 to move to drive the rolling brush assembly 40 to ascend relative to the body 200.

[0055] It should be noted that the above modes of the cleaning robot 1000 are only exemplary descriptions, and other modes can be added as needed.

[0056] Specifically, in some embodiments, during the process that the output end of the driving member 21 rotates in the first rotation direction, the roller brush assembly 40 rotates in the first direction, at this time, the roller brush assembly 40 can sweep 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 greater than the opening size of the suction port 11 in the deep cleaning mode or the deep cleaning enhanced mode; the height of the roller brush assembly 40 relative to the machine body 200 in the deep cleaning mode and the normal cleaning mode is less than the height of the roller brush assembly 40 relative to the machine body 200 in the lifting mode, or greater than the height of the roller brush assembly 40 relative to the machine body 200 in the depression mode, so that in the deep cleaning mode or the deep cleaning enhanced mode, the roller brush assembly 40 can perform deep cleaning on the surface to be cleaned (for example, the target area); in the normal cleaning mode, the roller brush assembly 40 can perform daily cleaning on the surface to be cleaned (for example, the non-target area); in the lifting mode, the roller brush assembly 40 can be lifted relative to the machine body 200 to facilitate obstacle crossing, entry and exit of the base station or execution of the mopping task, etc.; in the depression mode, the roller brush assembly 40 can be depressed relative to the machine body 200 to facilitate strong cleaning of stubborn stains on the surface to be cleaned. Wherein, during the process that the output end of the driving member 21 rotates in the second rotation direction, the cleaning device 100 can switch between the deep cleaning mode, the deep cleaning enhanced mode, the normal cleaning mode, the depression mode and the lifting mode, so that the cleaning device 100 can be suitable for different working scenes, improve the applicability of the cleaning device 100, and ensure the cleaning effect of the cleaning device 100. It should be noted that in some embodiments, during the process that the output end of the driving member 21 rotates in the second rotation direction, the cleaning device 100 can switch between the first state, the third state, the second state, the fourth state and the fifth state in turn.

[0057] Please refer to Figures 1 to 3 In some embodiments, the transmission member 23 comprises a first output end. The shielding assembly 50 comprises a shielding member 501 connected with the first output end of the transmission member 23, and the shielding member 501 can move 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 member 23 can be a part of the transmission member 23 that cooperates with the shielding member 501 and can transmit the driving force of the driving member 21 to the shielding member 50.

[0058] Specifically, in some embodiments, when the output end of the driving member 21 rotates in the second rotation direction, the driving force of the driving member 21 can be transmitted to the shielding member 501 through the first output end of the transmission member 23, and drive the shielding member 501 to move relative to the roller brush housing 10 to change the opening size of the suction port 11, so that the cleaning robot 1000 can be suitable for different working scenes, that is, the cleaning robot 1000 can effectively clean the surface to be cleaned when the current position of the cleaning robot 1000 is located in the target area or the non-target area, thereby improving the cleaning effect of the cleaning robot 1000.

[0059] Further, please refer to Figure 3 In some embodiments, the shielding member 501 includes a shielding piece 51 and a connecting piece 53. The shielding piece 51 is connected with the roller brush housing 10, and the shielding piece 51 is used to shield the opening of the suction port 11. One end of the connecting piece 53 is connected with the first output end of the transmission member 23, and the other end of the connecting piece 53 is connected with the shielding piece 51. When the connecting piece 53 moves in the first direction (A1 / A2), the shielding piece 51 moves relative to the roller brush housing 10 to switch between the first shielding position and the second shielding position. The opening size of the suction port 11 when the shielding piece 51 is in the first shielding position is larger than the opening size of the suction port 11 when the shielding piece 51 is in the second shielding position.

[0060] Specifically, in some embodiments, when the output end of the driving member 21 rotates in the second rotation direction, the driving force of the driving member 21 can be transmitted to the connecting piece 53 through the first output end of the transmission member 23, and drive the connecting piece 53 to move relative to the roller brush housing 10 in the first direction (A1 / A2) to drive the shielding piece 51 to move relative to the roller brush housing 10, so that the shielding piece 51 switches between the first shielding position and the second shielding position to change the opening size of the suction port 11, thereby changing the vacuum degree between the surface to be cleaned and the accommodation cavity 18 during working, so that the cleaning robot 1000 can be suitable for different working scenes and improve the cleaning effect.

[0061] It should be noted that, in some embodiments, the cross section of the shielding piece 51 cut by a plane perpendicular to the advancing 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 advancing direction X of the cleaning robot 1000. Thus, during the process of switching the shielding piece 51 from the first shielding position to the second shielding position, the shielding piece 51 can effectively shield the suction port 11 to reduce the opening size of the suction port 11.

[0062] Optionally, the shielding member 51 can be made of an elastic material, including but not limited to rubber, silica gel, and the like. Thus, during the process in which the cleaning device 100 cleans the garbage on the surface to be cleaned, the shielding member 51 can be elastically deformed to allow the garbage to smoothly enter the containing cavity 18 through the suction port 11, thereby preventing the shielding member 51 from blocking the garbage and improving the cleaning effect. In addition, the use of an elastic material can prevent the shielding member 51 from being damaged due to a rigid collision with hard garbage, thereby prolonging the service life of the shielding member 51 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.

[0063] Please refer to Figure 1 , Figure 2 and Figure 6 In some embodiments, the connecting member 53 includes a first sub-member 531 and a second sub-member 532. The first sub-member 531 is connected with the shielding member 51. The second sub-member 532 is provided with a matching member 56 connected with the first output end of the transmission member 23, and the second sub-member 532 is connected with the first sub-member 531. When the connecting member 53 moves in the first direction (A1 / A2), the second sub-member 532 is relatively stationary or moves relative to the first sub-member 531.

[0064] In some embodiments, the connecting member 53 includes a first sub-member 531 and a second sub-member 532. The first sub-member 531 is connected with the shielding member 51. The second sub-member 532 is provided with a matching member 56 connected with the first output end of the transmission member 23, and the second sub-member 532 is connected with the first sub-member 531. When the connecting member 53 moves in the first direction (A1 / A2), the second sub-member 532 is relatively stationary or moves relative to the first sub-member 531.

[0065] In this embodiment, one of the first sub-piece 531 and the second sub-piece 532 is provided with the protrusion 5301, and the other is provided with the accommodation space 5303, the bottom of the accommodation space 5303 is provided with the groove 5305 extending along the first direction (A1 / A2), the protrusion 5301 extends into the groove 5305 and can move along the first direction (A1 / A2) in the groove 5305. It should be noted that in some embodiments, the number relationship between the protrusion 5301 and the groove 5305 can be one-to-one; or multiple-to-one, that is, one protrusion 5301 corresponds to one groove 5305; or, multiple protrusions 5301 correspond to one groove 5305.

[0066] The accommodation space 5303 can guide the relative movement of the first sub-piece 531 and the second sub-piece 532, ensure the stability of the relative movement of the first sub-piece 531 and the second sub-piece 532, reduce the space occupied by the first sub-piece 531 and the second sub-piece 532, facilitate the installation and positioning of the first sub-piece 531 and the second sub-piece 532, and thus improve the assembly efficiency of the connecting piece 53.

[0067] Specifically, in some embodiments, the first sub-piece 531 is provided with the protrusion 5301, and the second sub-piece 532 is provided with the accommodation space 5303. In this case, when the first sub-piece 531 extends into the accommodation space 5303, the protrusion 5301 can extend into the groove 5305, so that the cooperation of the protrusion 5301 and the groove 5305 can limit the direction of the relative movement of the first sub-piece 531 and the second sub-piece 532, that is, limit the first sub-piece 531 and the second sub-piece 532 to only move relative to each other along the first direction (A1 / A2).

[0068] In one example, the groove 5305 can be a through groove, that is, the groove 5305 penetrates the bottom of the accommodation space 5303, so that when the relative movement of the first sub-piece 531 and the second sub-piece 532 is blocked, the cause of the failure can be quickly found out, for example, when the first sub-piece 531 and the second sub-piece 532 cannot move relative to each other, it can be convenient to observe whether the protrusion 5301 is stuck in the groove 5305, so as to ensure the stability and reliability of the working of the shielding assembly 50. In another example, the groove 5305 can be a blind groove, that is, the groove 5305 is recessed from the bottom of the accommodation space 5303 to a direction away from the center of the accommodation space 5303, but the groove 5305 does not penetrate the bottom of the accommodation space 5303, so that it can prevent impurities such as water or dust from the outside from entering the accommodation space 5303 to cause the shielding assembly 50 to be contaminated, so that the cleanliness of the cleaning device 100 can be ensured.

[0069] In the present embodiment, in the first direction (A1 / A2), the recess 5305 comprises opposite first and second side faces 5307, 5309, the first side face 5307 being closer to the matching piece 56 than the second side face 5309. The shielding member 501 further comprises a first elastic member 55 arranged between the first and second sub-members 531, 532. In the case where the connecting member 53 moves in the direct A1 of the first direction (A1 / A2), the protrusion 5301 abuts against the first side face 5307. In the case where the connecting member 53 moves in the reverse A2 of the first direction (A1 / A2), the first elastic member 55 is configured to keep the first and second sub-members 531, 532 relatively stationary. In the case where the force applied to the shielding member 51 exceeds a predetermined force threshold, the first elastic member 55 is compressed, the first and second sub-members 531, 532 move relatively, and the protrusion 5301 moves between the first and second side faces 5307, 5309.

[0070] In particular, in certain embodiments, in the case where the connecting member 53 moves in the direct A1 of the first direction (A1 / A2), the protrusion 5301 abuts against the first side face 5307, in which case the connecting member 53 can move the shielding member 51 in a direction away from the surface to be cleaned, for example, to switch the shielding member 51 from the second shielding position to the first shielding position; in the case where the connecting member 53 moves in the reverse A2 of the first direction (A1 / A2), the elastic force of the first elastic member 55 is configured to keep the first and second sub-members 531, 532 relatively stationary, in which case the protrusion 5301 still abuts against the first side face 5307, and the connecting member 53 can move the shielding member 51 in a direction towards the surface to be cleaned, for example, to switch the shielding member 51 from the first shielding position to the second shielding position. Also, in the case where the force applied to the shielding member 51 exceeds a predetermined force threshold, i.e., in the case where the external force applied to the shielding member 51 exceeds a predetermined force threshold, the first elastic member 55 is compressed, in which case the first and second sub-members 531, 532 move relatively, i.e., the shielding member 51 moves relatively to the connecting member 53, which can thus cushion the force applied to the shielding member 51, preventing the shielding member 51 from rigidly colliding with obstacles or protrusions on the surface to be cleaned, which can cause damage, and ensuring normal operation of the cleaning device 100.

[0071] Exemplarily, in the case that the first elastic member 55 comprises a compression spring, opposite ends of the compression spring are connected with the first sub-member 531 and the second sub-member 532 respectively. In the case that the protrusion 5301 abuts against the first side surface 5307, the compression spring is in a compressed state and has a certain compression allowance. The compression spring can also be in an extended state. The second sub-member 532 can push the first sub-member 531 to move to drive the shielding member 51 to move relative to the rolling brush shell 10. In the case that the shielding member 51 is subjected to an action force exceeding a preset action force threshold, the compression spring is compressed to enable the relative movement of the first sub-member 531 and the second sub-member 532, and the compression spring can absorb the action force to which the shielding member 51 is subjected. In the case that the action force to which the shielding member 51 is subjected disappears, the elastic force generated by the compression of the compression spring can enable the shielding member 51 to return to the position before the movement.

[0072] It can be understood that, in the case that the protrusion 5301 abuts against the first side surface 5307, the shielding member 51 is not subjected to an action force (the action force refers to a force other than the force applied to the shielding member 51 by the first elastic member 55); or, the action force to which the shielding member 51 is subjected is less than the preset action force threshold.

[0073] In some embodiments, the side wall opposite to the first sub-member 531 of the second sub-member 532 can be provided with a protruding structure; or, the side wall opposite to the second sub-member 532 of the first sub-member 531 can be provided with a protruding structure. Thus, compared with the direct abutment of the first sub-member 531 and the second sub-member 532, the setting of the protruding structure can reduce the friction between the first sub-member 531 and the second sub-member 532, so that the relative movement of the first sub-member 531 and the second sub-member 532 is more smooth. The protruding structure in the present embodiment is basically the same as the first protruding structure 537 in the above-mentioned embodiments, and thus will not be described herein.

[0074] Please refer to Figure 2 In some embodiments, the rolling brush shell 10 is provided with a guide member 15, and the guide member 15 is used to guide the movement of the connecting member 53 along the first direction (A1 / A2). One of the guide member 15 and the connecting member 53 is provided with a guide groove, and the other is provided with a guide column. At least part of the guide column is accommodated in the guide groove, and the guide column and the guide groove are in sliding connection. Exemplarily, the guide member 15 is provided with the guide groove, the connecting member 53 is provided with the guide column, at least part of the connecting member 53 is accommodated in the guide member 15, and the guide member 15 guides the movement of the connecting member 53 along the first direction (A1 / A2).

[0075] Specifically, in some embodiments, the guide member 15 is provided with a guide slot, the connecting member 53 is provided with a guide post, the guide member 15 is recessed from the outer side wall of the roller brush housing 10 towards the center of the roller brush housing 10, and at least part of the connecting member 53 is arranged in the guide member 15. Thus, the guide member 15 can limit the movement direction and stroke of the connecting member 53 relative to the roller brush housing 10 while guiding the movement of the connecting member 53 in the first direction (A1 / A2), preventing the movement direction and stroke of the connecting member 53 in the first direction (A1 / A2) from being unlimited when the driving member 21 malfunctions, which can cause the connecting member 53 to collide with other structures of the cleaning device 100 and be damaged, thereby ensuring the stability and reliability of the operation of the cleaning device 100.

[0076] Please refer to Figure 6 In some embodiments, in a direction perpendicular to the first direction (A1 / A2), the guide member 15 includes opposite first and second guide side walls 151 and 153, and the connecting member 53 includes opposite first and second connecting side walls 535 and 536, the first connecting side wall 535 and the first guide side wall 151 are in sliding fit, and the second connecting side wall 536 and the second guide side wall 153 are in sliding fit. Further, in some embodiments, one of the first connecting side wall 535 and the first guide side wall 151 is provided with a guide slot, and the other is provided with a guide post; one of the second connecting side wall 536 and the second guide side wall 153 is provided with a guide slot, and the other is provided with a guide post. For example, the first connecting side wall 535 is provided with a guide post, and the first guide side wall 151 is provided with a guide slot; the second connecting side wall 536 is provided with a guide post, and the second guide side wall 153 is provided with a guide slot. In this way, on the one hand, the sliding resistance of the connecting member 53 in the guide member 15 can be reduced, the power consumption required for the driving assembly 20 to drive the movement of the shielding member 501 can be reduced, and the endurance time of the cleaning robot 1000 can be increased; on the other hand, the possibility of the connecting member 53 being stuck in the guide member 15 can be reduced, the normal movement of the connecting member 53 in the first direction (A1 / A2) can be ensured, and the stability and reliability of the operation of the shielding member 501 can be improved.

[0077] Further, in some embodiments, the first connecting side wall 535 is provided with a first protruding structure 537 protruding and extending away from the second connecting side wall 536, and the first protruding structure 537 abuts against the first guide side wall 151.

[0078] Specifically, the first protruding structure 537 can include a plurality of spaced protrusions, the protrusions protruding from the first connecting sidewall 535 towards a direction away from the second connecting sidewall 536, and in the case that the connecting member 53 is arranged in the guide member 15, the protrusions abut against the first guide sidewall 151. Thus, compared with the case that the first connecting sidewall 535 directly abuts 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 connecting member 53 and the guide member 15, and in turn, on the one hand, the power consumption required for the driving assembly 20 to drive the movement of the shielding member 501 can be reduced, and the endurance time of the cleaning robot 1000 can be increased; on the other hand, the possibility of the connecting member 53 being stuck in the guide member 15 can be reduced, the normal movement of the connecting member 53 in the first direction (A1 / A2) can be ensured, and the stability and reliability of the shielding member 501 in operation can be improved.

[0079] It can be understood that in other embodiments, the first guide sidewall 151 can be provided with a first protruding structure 537, the first protruding structure 537 protruding from the first guide sidewall 151 towards a direction close to the second guide sidewall 153, and the first protruding structure 537 abutting against the first connecting sidewall 535. In this embodiment, the structure of the first protruding structure 537 is basically the same as that of the first protruding structure 537 in the above-mentioned embodiment, and will not be described here.

[0080] In some embodiments, the second connecting sidewall 536 is provided with a second protruding structure, the second protruding structure protruding from the second connecting sidewall 536 towards a direction away from the first connecting sidewall 535, and the second protruding structure abutting against the second guide sidewall 153.

[0081] Specifically, the second protruding structure can include a plurality of spaced protrusions, the protrusions protruding from the second connecting sidewall 536 towards a direction away from the first connecting sidewall 535, and in the case that the connecting member 53 is arranged in the guide member 15, the protrusions abut against the second guide sidewall 153. Thus, compared with the case that the second connecting sidewall 536 directly abuts against the second guide sidewall 153, the arrangement of 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 connecting member 53 and the guide member 15, and in turn, on the one hand, the power consumption required for the driving assembly 20 to drive the movement of the shielding member 501 can be reduced, and the endurance time of the cleaning robot 1000 can be increased; on the other hand, the possibility of the connecting member 53 being stuck in the guide member 15 can be reduced, the normal movement of the connecting member 53 in the first direction (A1 / A2) can be ensured, and the stability and reliability of the shielding member 501 in operation can be improved.

[0082] It can be understood that, in other embodiments, the second guide side wall 153 is provided with a second protruding structure, the second protruding structure protrudes from the second guide side wall 153 towards the first guide side wall 151, and the second protruding structure is in abutment with the second connecting side wall 536. The structure of the second protruding structure in the embodiment is basically the same as that of the second protruding structure in the above embodiment, and will not be described here.

[0083] Referring to Figure 2 and Figure 4 In some embodiments, the shielding member 51 is rotatably connected to the cover 12, the shielding member 51 is not in contact with the surface to be cleaned in the first shielding position, and the shielding member 51 is in contact with the surface to be cleaned in the second shielding position.

[0084] Specifically, in some embodiments, the first output end of the transmission member 23 transmits the driving force output by the driving member 21 to the shielding member 51, and the shielding member 51 can rotate relative to the cover 12 to move between the first shielding position and the second shielding position. In the first shielding position, the shielding member 51 is not in contact with the surface to be cleaned, at this time, the opening of the suction port 11 is larger, and the cleaning robot 1000 can clean the non-target area; in the second shielding position, the shielding member 51 is in contact with the surface to be cleaned, at this time, the opening of the suction port 11 is smaller, and the cleaning robot 1000 can clean the target area.

[0085] Further, referring to Figure 6 In some embodiments, the shielding member 51 includes two connecting arms 511 and a shielding portion 513. One end of the two connecting arms 511 is rotatably connected to the cover 12. The shielding portion 513 is connected to the other end of the two connecting arms 511, for example, the shielding member 51 is in the shape of U. The shielding portion 513 is arranged on the side of the first edge 103 of the cover 12, and in the case of rotating the connecting arms 511 relative to the cover 12, the gap between the shielding portion 513 and the surface to be cleaned is changed by driving the shielding portion 513 to move, so as to change the opening size of the suction port 11. Exemplarily, the opening size of the suction port 11 can be the height of the shielding portion 513 relative to the surface to be cleaned in the direction perpendicular to the surface to be cleaned, that is, in the direction perpendicular to the surface to be cleaned, the greater the height of the shielding portion 513 relative to the surface to be cleaned, the greater the opening size of the suction port 13.

[0086] Specifically, in some embodiments, the shielding portion 513 can be in a flat plate shape or an arc plate shape, etc. In one example, in the case where the shielding portion 513 is in a flat plate shape, the plane where the shielding portion 513 is located is parallel to the height direction of the cleaning robot 1000, in which case, the plane where the shielding portion 513 is located is substantially perpendicular to the surface to be cleaned. In another example, in the case where the shielding portion 513 is in a flat plate shape, the angle between the plane where the shielding portion 513 is located and the height direction of the cleaning robot 1000 is an acute angle, and in the advancing direction X of the cleaning robot 1000, the distance between the shielding portion 513 and the surface to be cleaned gradually increases. In this way, the shielding portion 513 can gather garbage (such as dust or particulate matter, etc.) to the suction port 11, thereby improving the cleaning effect of the cleaning device 100.

[0087] In some embodiments, the connecting arm 511 and the shielding portion 513 can be an integral structure, that is, the connecting arm 511 and the shielding portion 513 can be formed in an integral manner to form an integral structure, thereby improving the bonding strength between the connecting arm 511 and the shielding portion 513, preventing the problem of cracking between the connecting arm 511 and the shielding portion 513 during the cleaning process of the cleaning device 100, and 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 portion 513 can be a split structure, that is, the connecting arm 511 and the shielding portion 513 are two different structures. The connecting arm 511 and the shielding portion 513 can be combined together in a non-detachable connection manner or a detachable connection manner, wherein the non-detachable connection manner includes but is not limited to bonding or welding, etc.; the detachable connection manner includes but is not limited to snap connection or threaded connection, etc.

[0088] Please refer to Figure 2 and Figure 6 In some embodiments, the shielding member 51 further includes an abutting portion 515, which is disposed on the side of the shielding portion 513 opposite to the connecting member 53, and the abutting portion 515 is connected with the connecting member 53.

[0089] Specifically, in some embodiments, the abutting portion 515 can protrude and extend from the shielding portion 513 towards the connecting member 53, and in the case where the cleaning device 100 is assembled, the abutting portion 515 can abut against the connecting member 53. In this way, in the case where the connecting member 53 moves in the reverse direction A2 relative to the roller brush housing 10 along the first direction (A1 / A2), the connecting member 53 can apply a force to the shielding member 51 through the abutting portion 515 to drive the shielding member 51 to switch from the first shielding position to the second shielding position. Moreover, the provision of the abutting portion 515 can facilitate the installation and positioning of the shielding member 51 and the connecting member 53, thereby improving the assembly efficiency of the cleaning device 100.

[0090] Please refer to Figure 1In some embodiments, the shielding assembly 50 further comprises a second elastic member 505 arranged between the shielding member 51 and the roller brush housing 10, and the second elastic member 505 is configured to provide a force to move the shielding member 51 towards the first shielding position.

[0091] Specifically, in some embodiments, when the connecting member 53 moves in the reverse direction A2 of the first direction (A1 / A2), the connecting member 53 exerts a force on the shielding member 51 to move the shielding member 51 relative to the roller brush housing 10 towards the second shielding position, and in this case, the second elastic member 505 generates an elastic force; when the connecting member 53 moves in the forward direction A1 of the first direction (A1 / A2), the connecting member 53 does not exert a force on the shielding member 51, and in this case, the elastic force generated by the second elastic member 505 can move the shielding member 51 towards the first shielding position. Thus, the arrangement of the second elastic member 505 can facilitate the movement of the shielding member 51 relative to the roller brush housing 10 to switch between the first shielding position and the second shielding position, and reduce the power consumption of the driving member 21 during the movement of the shielding member 51, i.e., the driving of the driving member 21 can not be needed when the shielding member 51 moves relative to the roller brush housing 10 towards the first shielding position, thereby facilitating the increase of the endurance time of the cleaning robot 1000.

[0092] It should be noted that, in some embodiments, the second elastic member 505 can be a tension spring or a torsion spring, etc. For example, when the second elastic member 505 is a torsion spring, the second elastic member 505 is arranged between the connecting arm 511 and the roller brush housing 10. In this case, when the connecting member 53 moves in the reverse direction A2 of 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 of the first direction (A1 / A2), the elastic force generated by the torsion spring can move the shielding member 51 towards the first shielding position.

[0093] In one example, the second elastic member 505 comprises one, and in this case, the second elastic member 505 can be connected to the middle position of the shielding member 51 in the direction perpendicular to the advancing direction X and the height direction Z of the cleaning robot 1000, thereby ensuring the stability of the movement of the shielding member 51 relative to the roller brush housing 10. In another example, the second elastic member 505 comprises two, and the two second elastic members 505 can be arranged at the opposite ends of the shielding member 51 in the direction perpendicular to the advancing direction X and the height direction Z of the cleaning robot 1000.

[0094] Please refer to Figure 1 and Figure 2In some embodiments, the transmission component 23 comprises a second output end. The lifting assembly 60 comprises a connecting shaft 61 and a lifting member 63. The connecting shaft 61 is fixedly installed on the brush housing 10. The lifting member 63 is rotatably sleeved on the connecting shaft 61 and can be engaged with or disengaged from the second output end of the transmission component 23. When the second output end of the transmission component 23 is engaged with the lifting member 63, the lifting member 63 rotates around 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. When the second output end of the transmission component 23 is disengaged from the lifting member 63, the lifting member 63 rotates around the connecting shaft 61 in the reverse direction B1 of the second direction (B1 / B2) to switch from the second lifting position to the first lifting position. The distance between the brush assembly 40 and the surface to be cleaned when the lifting member 63 is in the first lifting position is less than the distance between the brush assembly 40 and the surface to be cleaned when the lifting member 63 is in the second lifting position. It should be noted that, in some embodiments, the second output end of the transmission component 23 can be a part of the transmission component 23 that can be engaged with the lifting assembly 60 and can transmit the driving force of the driving member 21 to the shielding component 501.

[0095] In some embodiments, the lifting assembly 60 further comprises a restoring member 64 connected with 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 to make the lifting member 63 rotate around the connecting shaft 61 in the reverse direction B1 of the second direction (B1 / B2) to switch from the second lifting position to the first lifting position. That is, the lifting member 63 can be restored to the original position by the force provided by the restoring member 64 without the need of the driving assembly 20 to output power to drive, which can save power. Exemplarily, the restoring member 64 can be a torsional spring. The torsional spring 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 torsional spring is deformed under force. When the second output end of the transmission component 23 is disengaged from the lifting member 63, the torsional spring restores to the original state to provide a force to the lifting member 63 to make it restore to the first lifting position from the second lifting position.

[0096] Exemplarily, when the second output end of the transmission component 23 cooperates with the lifting member 63, the lifting member 63 rotates around 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, and the lifting member 63 exerts a force (for example, presses the support 210 of the machine body 200 downward in the direction of the surface to be cleaned) on the support 210 of the machine body 200, so that the rolling brush housing 10 rotates around the rotating shaft 220 (the rotating arm 16 of the rolling brush housing 10 is connected to the machine body 200 through the rotating shaft 220), so as to realize the upward lifting of the rolling brush housing 10, thereby driving the rolling brush assembly 40 to rise. It can be understood that when the second output end of the transmission component 23 cooperates with the lifting assembly 60, the rolling brush housing 10 can be lifted or lowered, and since the rolling brush assembly 40 is connected to the rolling brush housing 10, it is driven to rise or fall together with the rolling brush housing 10.

[0097] Specifically, in some embodiments, when the output end of the driving member 21 rotates in the second rotation direction, the driving force of the driving member 21 can be transmitted to the lifting member 63 through the second output end of the transmission component 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 rolling brush assembly 40 to rise and fall relative to the machine body 200, which on the one hand can facilitate the cleaning robot 1000 to overcome obstacles, and improve the passing performance of the cleaning robot 1000; on the other hand, it is beneficial to adapt the cleaning robot 1000 to different cleaning environments, and improve the cleaning effect of the cleaning robot 1000.

[0098] Please refer to Figure 1 In this embodiment, the lifting member 63 includes a sleeving portion 631 and a clamping portion 633. The sleeving portion 631 is rotatably sleeved on the connecting shaft 61. The clamping portion 633 is connected with the sleeving portion 631 and extends from the sleeving portion 631, and the clamping portion 633 is used to exert a force on the support 210 in the machine body 200, so as to make the support 210 exert a reaction force on the cleaning device 100 to lift the support 210.

[0099] In some embodiments, the sleeve portion 631 and the hook portion 633 can be an integral structure, i.e., the sleeve portion 631 and the hook portion 633 can be formed in an integral manner, thereby improving the bonding strength between the sleeve portion 631 and the hook portion 633, preventing the sleeve portion 631 and the hook portion 633 from being broken when the lifting member 63 is engaged with the bracket 210, and thus improving the stability and reliability of the cleaning device 100.

[0100] Further, in some embodiments, the sleeve portion 631 is provided with a sleeve protrusion 6311, which is capable of being engaged with the second output end of the transmission member 23.

[0101] Specifically, in some embodiments, when the driving force of the driving 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 exerts a force on the bracket 210 in the machine body 200, thereby causing the bracket 210 to exert a reaction force on the cleaning device 100 through the lifting member 63 to lift the cleaning device 100 relative to the bracket 210.

[0102] Please refer to Figures 1 to 5 In some embodiments, the transmission member 23 comprises a third output end, which is connected with the roller brush 41. The roller brush 41 is driven to rotate relative to the roller brush cavity shell 14 by the driving member 21. It should be noted that, in some embodiments, the third output end of the transmission member 23 can be a part of the transmission member 23, which is capable of being engaged with the roller brush 41 and transmitting the driving force of the driving member 21 to the roller brush 41.

[0103] Specifically, in some embodiments, when the output end of the driving member 21 rotates in the first rotation direction, the driving force of the driving 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 the cleaning of the surface to be cleaned.

[0104] In some embodiments, the transmission component 23 comprises a fourth output end; the pressing assembly 70 comprises a pressing member 71, the pressing member 71 is connected with the fourth output end of the transmission component 23, the pressing member 71 is driven by the driving member 21 to cooperate or disengage with the brush housing 10, when the pressing member 71 moves to cooperate with the brush housing 10, the pressing member 71 switches from the second pressing position to the first pressing position, when the pressing member 71 moves to disengage with the brush housing 10, the pressing member 71 switches from the first pressing position to the second pressing position, the distance between the brush assembly 40 and the surface to be cleaned when the pressing member 71 is in the first pressing position is smaller than the distance between the brush assembly 40 and the surface to be cleaned when the pressing member 71 is in the second pressing position. It should be noted that, in some embodiments, the fourth output end of the transmission component 23 can be a part of the transmission component 23 which can cooperate with the pressing member 71 and can transmit the driving force of the driving member 21 to the pressing member 71. It should be noted that, the first pressing position and the second pressing position are not fixed positions, but are position intervals which allow adjustment within a certain range.

[0105] Specifically, in some embodiments, when the output end of the driving member 21 rotates in the second rotation direction, the driving force of the driving member 21 can be transmitted to the pressing member 71 through the fourth output end of the transmission component 23 to drive the pressing member 71 to cooperate or disengage with the brush housing 10, so as to lift or lower the brush assembly 40 relative to the body 200.

[0106] Please refer to Figure 2 and Figure 3 In some embodiments, the transmission component 23 comprises 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 with the output end of the driving member 21. The input end of the second transmission unit 233 is connected with 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 with the brush assembly 40. The output end of the third transmission unit 235 (i.e. the first output end of the transmission component 23 and the second output end of the transmission component 23) is connected with the shielding assembly 50, the lifting assembly 60, or the pressing assembly 70. One end of the clutch unit 237 is connected with the second output end of the first transmission unit 231, and the other end of the clutch unit 237 is connected with the input end of the third transmission unit 235, and the clutch unit 237 is used to make 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 communicate or disconnect.

[0107] Specifically, in some embodiments, when the output end of the driving member 21 rotates in the first rotation direction, the driving force of the driving member 21 can be transmitted to the first transmission unit 231, and then transmitted to the rolling brush assembly 40 through the first output end of the first transmission unit 231 and the second transmission unit 233 in sequence, so as to drive the rolling brush assembly 40 to move; when the output end of the driving member 21 rotates in the second rotation direction, the driving force of the driving member 21 can be transmitted to the first transmission unit 231, and then transmitted to the shielding assembly 50, the lifting assembly 60 or the pressing-down assembly 70 through the second output end of the first transmission unit 231, the clutch unit 237 and the third transmission unit 235 in sequence, so as to drive the shielding assembly 50, the lifting assembly 60 or the pressing-down assembly 70 to move.

[0108] It can be understood that, when the output end of the driving member 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 driving member 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, so as to prevent the lifting assembly 60, the shielding assembly 50 and the pressing-down assembly 70 from moving and affecting the cleaning of the rolling brush assembly 40 to the surface to be cleaned during the movement of the rolling brush assembly 40, thereby ensuring the normal operation of the cleaning device 100.

[0109] Further, in some embodiments, the first transmission unit 231 comprises a first rotation shaft 2311 rotatably mounted on the rolling brush housing 10, and the third transmission unit 235 comprises a second rotation shaft 2351 rotatably mounted on the rolling brush housing 10. For example, the first transmission unit 231, the second transmission unit 233 and the third transmission unit 235 in the embodiments of the present disclosure are all gear and transmission shaft structures, which can be adjusted to other transmission modes according to actual needs.

[0111] Specifically, in some embodiments, the one-way clutch 2377 can include a one-way bearing, one of the first sub-portion and the second sub-portion is an inner ring of the one-way bearing, and the other of the first sub-portion and the second sub-portion is an outer ring of the one-way bearing. Wherein, the first sub-portion is only free to rotate in a clockwise direction or a counterclockwise direction relative to the second sub-portion, for example, the first sub-portion is free to rotate in the clockwise direction relative to the second sub-portion, and is locked in the counterclockwise direction; or, the first sub-portion is free to rotate in the counterclockwise direction relative to the second sub-portion, and is locked in the clockwise direction. Thus, in the case that the first sub-portion is connected with the second output end of the first transmission unit 231, and the second sub-portion is connected with the input end of the third transmission unit 235, the first sub-portion and the second sub-portion can control 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 to be connected or disconnected according to the rotation direction of the second output end of the first transmission unit 231.

[0112] Further, in some embodiments, in the case that the output end of the driving member 21 rotates in a first rotation direction, the transmission between the first sub-portion and the second sub-portion is disconnected, 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. In the case that the output end of the driving member 21 rotates in a second rotation direction, the transmission between the first sub-portion and the second sub-portion is connected, 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, the first rotation direction is opposite to the second rotation direction.

[0113] Please refer to Figure 2 and Figure 3 In some embodiments, the third transmission unit 235 includes a moving member 2352, the moving member 2352 is connected with the clutch unit 237, in the case that the driving force of the driving member 21 is transmitted to the moving member 2352, the moving member 2352 moves relative to the roller brush housing 10 to drive the roller brush assembly 40, the shielding assembly 50, the lifting assembly 60 or the pressing-down assembly 70 to operate.

[0114] Further, in some embodiments, the moving member 2352 includes a general transmission portion 2355, a first transmission portion 2358, a second transmission portion 2359 and the pressing-down assembly 70, the general transmission portion 2355 is connected with the clutch unit 237, in the case that the driving force of the driving member 21 is transmitted to the general transmission portion 2355, the first transmission portion 2358, the second transmission portion 2359 and the pressing-down assembly 70 simultaneously rotate relative to the roller brush housing 10. Exemplarily, the general transmission portion 2355, the first transmission portion 2358, the second transmission portion 2359 and the pressing-down assembly 70 can be coaxially connected, that is, the general transmission portion 2355, the first transmission portion 2358, the second transmission portion 2359 and the pressing-down assembly 70 are connected on the same shaft (for example, the second rotation shaft 2351).

[0115] Further, in some embodiments, the first transmission part 2358 is provided with a protruding part 23581, in the case that the driving force of the driving member 21 is transmitted to the first transmission part 2358, the first transmission part 2358 rotates relative to the rolling brush shell 10 to drive the protruding part 23581 to drive the lifting assembly 60 to move. The second transmission part 2359 is provided with a connecting part 23591, the connecting part 23591 is eccentrically arranged relative to the second transmission part 2359, in the case that the second transmission part 2359 rotates relative to the rolling brush shell 10 together with the first transmission part 2358, the connecting part 23591 drives the shielding assembly 50 to operate. The pressing-down assembly 70 is provided with a pressing-down member 71, in the case that the pressing-down assembly 70 rotates relative to the rolling brush shell 10, the pressing-down member 71 moves to drive the rolling brush shell 10 to move. Exemplarily, one end of the pressing-down member 71 can be fixedly arranged on the second rotating shaft 2351 (rotatably mounted on the rolling brush shell 10) to rotate with the second rotating shaft 2351. The cross-sectional shape of the pressing-down member 71 can be substantially fan-shaped.

[0116] Specifically, in some embodiments, the first transmission part 2358 can include a first body part 23583, the first body part 23583 can be fixedly arranged on the second rotating shaft 2351 (rotatably mounted on the rolling brush shell 10), the protruding part 23581 extends outwardly from the peripheral wall of the first body part 23583 away from the central axis of the first body part 23583, for example, the cross-sectional shape of the first transmission part 2358 can be designed as a water droplet shape; the second transmission part 2359 can include a second body part 23593, the second body part 23593 can be fixedly arranged on the second rotating shaft 2351, the connecting part 23591 extends outwardly from the second body part 23593 away from the first body part 23583. Wherein, the central axes of the first body part 23583 and the second body part 23593 can coincide. It should be noted that, in some embodiments, the cross-sectional shape of the protruding part 23581 can be substantially triangular.

[0117] Please refer to Figure 1 , Figure 5 and Figure 8 , in some embodiments, in the case that the driving force of the driving member 21 is transmitted to the total transmission part 2355, the first transmission part 2358, the second transmission part 2359 and the pressing-down assembly 70 rotate together relative to the rolling brush shell 10, so that the moving member 2352 includes at least one of the first movement state, the second movement state, the third movement state and the fourth movement state, wherein: referring to the area A (smaller fan-shaped on the left side) in a, in the first movement state, the connecting part 23591 cooperates with the shielding member 51 of the shielding assembly 50 to drive the shielding member 51 of the shielding assembly 50 to move to change (including increase or decrease) the opening size of the suction port 11; correspondingly, Figure 8 Figure 8 ​In area a except area A, the connecting part 23591 is disengaged from the shield piece 51 of the shield assembly 50, i.e. does not drive the shield piece 51 of the shield assembly 50 to move; see Figure 8 In area B (the upper sector, i.e. the area except areas A, C, D) in b, in the second movement state, the connecting part 23591 is disengaged from the shield piece 51 of the shield assembly 50, the protruding part 23581 is disengaged from the lifting assembly 60, and the pressing piece 71 is disengaged from the brush housing 10, i.e. does not drive the shield piece 51 of the shield assembly 50 to move, does not drive the lifting assembly 60 to move, and does not drive the pressing assembly 70 to move; see Figure 8 In area C (the right sector) in c, in the third movement state, the protruding part 23581 is engaged with the lifting assembly 60 to drive the lifting assembly 60 to move to drive the brush housing 10 to lift (including rising or falling), thereby driving the brush assembly 40 to lift (including rising or falling) relative to the machine body 200; correspondingly, Figure 8 In area c except area C, the protruding part 23581 is disengaged from the lifting assembly 60, i.e. does not drive the lifting assembly 60 to move; see Figure 8 In area D (the lower sector) in d, in the fourth movement state, the pressing piece 71 is engaged with the brush housing 10 to drive the brush housing 10 to lift (including rising or falling) to drive the brush assembly 40 to lift (including rising or falling) relative to the machine body 200; correspondingly, Figure 8 In area d except area D, the pressing piece 71 is disengaged from the brush housing 10, i.e. does not drive the pressing piece 71 to move.

[0118] At a certain moment, two or more of the above four movement states of the moving part 2352 can coexist, for example, in the deep cleaning enhanced mode, the first movement state and the fourth movement state can coexist (see Figure 8 The shaded area E in e, i.e. the intersection area of areas A and D, i.e. the connecting part 23591 is engaged with the shield piece 51 of the shield assembly 50 to drive the shield piece 51 of the shield assembly 50 to move to reduce the opening size of the suction port 11, and the pressing piece 71 is engaged with the brush housing 10 to drive the brush housing 10 to fall to drive the brush assembly 40 to fall relative to the machine body 200.

[0119] It should be noted that, Figure 9 The sizes and positions of areas A, B, C, and D in a-e are only exemplary and can be adjusted as needed, for example, by adjusting the positions, sizes, and shapes of the first transmission part 2358, the second transmission part 2359, and the pressing assembly 70 to adjust the sizes and positions of areas A, B, C, and D and the sizes and positions of the intersection areas of areas A, B, C, and D.

[0120] It can be understood that, when the moving part 2352 is in the first movement state, the cleaning device 100 is in the first state; when the moving part 2352 is in the second movement state, the cleaning device 100 is in the second state; when the moving part 2352 is in the third movement state, the cleaning device 100 is in the third state; when the moving part 2352 is in the fourth movement state, the cleaning device 100 is in the fourth state; and when the moving part 2352 is in the fourth movement state and the fifth movement state at the same time, the cleaning device 100 is in the fifth state.

[0121] In some embodiments, when the protrusion 23581 cooperates with the lifting assembly 60, the lifting assembly 60 is located at the second lifting position, and the rolling brush assembly 40 is at the first height relative to the machine body 200; and when the protrusion 23581 is disengaged from the lifting assembly 60, the lifting assembly 60 is located at the first lifting position, and the rolling brush assembly 40 is at the second height relative to the machine body 200. The first height is greater than the second height.

[0122] Specifically, in some embodiments, the cooperation of the protrusion 23581 with the lifting assembly 60 can be that the sleeving protrusion 6311 abuts against the protrusion 23581; and the disengagement of the protrusion 23581 from the lifting assembly 60 can be that the sleeving protrusion 6311 does not abut against the protrusion 23581. Wherein, when the moving part 2352 rotates relative to the rolling brush housing 10 to make the protrusion 23581 cooperate with the sleeving protrusion 6311, the sleeving protrusion 6311 can drive the sleeving part 631 and the hook part 633 to rotate about the connecting shaft 61, so that the lifting assembly 60 is located at the second lifting position, and the rolling brush assembly 40 is at the first height relative to the machine body 200; and when the moving part 2352 rotates relative to the rolling brush housing 10 to make the protrusion 23581 disengage from the sleeving protrusion 6311, the sleeving part 631 and the hook part 633 can rotate reversely about the connecting shaft 61, so that the lifting assembly 60 is located at the first lifting position, and the rolling brush assembly 40 is at the second height relative to the machine body 200. Thus, the driving assembly 20 can drive the lifting assembly 60 to move, so as to switch the rolling brush assembly 40 between the first height and the second height, thereby improving the obstacle-crossing ability of the cleaning device 100 and ensuring the normal work of the cleaning device 100.

[0123] In some embodiments, the coupling portion 23591 is configured to rotate relative to the roller brush housing 10 to a first orientation, and the coupling portion 23591 is disengaged from the blocking member 51 of the blocking assembly 50, and the blocking member 51 of the blocking assembly 50 is in the first blocking position relative to the roller brush housing 10; the coupling portion 23591 is configured to rotate relative to the roller brush housing 10 to a second orientation, and the coupling portion 23591 is engaged with the blocking member 51 of the blocking assembly 50, and the blocking member 51 of the blocking assembly 50 is in the second blocking position relative to the roller brush housing 10; the opening size of the suction inlet 11 when the blocking member 51 is in the first blocking position is greater than the opening size of the suction inlet 11 when the blocking member 51 is in the second blocking position. Thus, the blocking member 51 can be switched between the first blocking position and the second blocking position relative to the roller brush housing 10 when the coupling portion 23591 rotates relative to the roller brush housing 10, so as to switch the opening size of the suction inlet 11, thereby enabling the cleaning device 100 to be suitable for different working scenarios and improving the applicability of the cleaning robot 1000. Figures 1 to 3 It should be noted that the first orientation and the second orientation are not fixed positions, but are position intervals that allow adjustment within a certain range.

[0124] In some embodiments, the pressing member 71 is configured to be engaged with the roller brush housing 10 when the pressing member 71 is in the first pressing position, and the roller brush assembly 40 is in the third height relative to the body 200; the pressing member 71 is disengaged from the roller brush housing 10 when the pressing member 71 is in the second pressing position, and the roller brush assembly 40 is in the fourth height relative to the body 200, and the third height is less than the fourth height. Thus, the pressing member 71 can be selectively engaged with the roller brush housing 10 to switch the roller brush assembly 40 between the third height and the fourth height relative to the body 200, thereby enabling the cleaning device 100 to be suitable for different working scenarios and improving the applicability of the cleaning robot 1000. For example, the cleaning device 100 can clean the target area when the roller brush assembly 40 is in the third height relative to the body 200.

[0125] Please refer to Figure 1 In some embodiments, the cleaning device 100 further comprises a detection assembly 80, which is arranged on the roller brush housing 10 and the transmission member 23, and is configured to detect the position of the moving member 2352 in the transmission member 23 relative to the roller brush housing 10.

[0126] The detection assembly 80 is arranged to enable the cleaning device 100 to obtain the current position of the moving part 2352, and to obtain the positions of the shielding assembly 50, the lifting assembly 60 and the pressing assembly 70 relative to the brush housing 10 according to the current position of the moving part 2352, thereby facilitating the timely and accurate adjustment of the position of the moving part 2352 by the cleaning device 100, and achieving the adjustment of the position of the shielding assembly 50, and ensuring the stability and reliability of the operation of the cleaning device 100.

[0127] Further, in some embodiments, the detection assembly 80 comprises a first detection part 81 and a second detection part 83, one of the first detection part 81 and the second detection part 83 is arranged on the brush housing 10, and the other is arranged on the moving part 2352, and the first detection part 81 and the second detection part 83 cooperate to detect the position of the moving part 2352 relative to the brush housing 10.

[0128] Specifically, in some embodiments, one of the first detection part 81 and the second detection part 83 can be an electromagnetic sensor (such as a Hall sensor, etc.), an optoelectronic sensor (such as a laser sensor, etc.) or an ultrasonic sensor, etc., and the other can be a component capable of cooperating with the electromagnetic sensor (such as a Hall sensor, etc.), the optoelectronic sensor (such as a laser sensor, etc.) or the ultrasonic sensor, etc., whereby the first detection part 81 and the second detection part 83 can cooperate to jointly detect the moving position of the moving part 2352 relative to the brush housing 10.

[0129] For example, one of the first detection part 81 and the second detection part 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 the light, and to indicate the position of the moving part 2352 relative to the brush housing 10 according to the received light.

[0130] In other embodiments, the cleaning device 100 further comprises a detection assembly 80 arranged on the brush housing 10 and at least one of the shielding assembly 50, the lifting assembly 60 and the pressing assembly 70, the detection assembly 80 is used to detect the position of the shielding part 51 of the shielding assembly 50 relative to the brush housing 10, the position of the lifting part 63 of the lifting assembly 60 relative to the brush housing 10, and / or the position of the brush of the brush assembly 40 relative to the brush housing 10.

[0131] The detection assembly 80 is arranged to enable the cleaning device 100 to directly obtain the positions of the shielding part 51, the lifting part 63 and / or the pressing part 71 relative to the brush housing 10, thereby facilitating the adjustment of the positions of the shielding assembly 50, the lifting assembly 60 and the pressing assembly 70 by the cleaning device 100, and ensuring the stability and reliability of the operation of the cleaning device 100.

[0132] Further, in some embodiments, the detection assembly 80 comprises a first detection member 81 and a second detection member 83, one of which is arranged on the roller brush housing 10, and the other of which is arranged on the shielding assembly 50, the lifting assembly 60 and / or the pressing assembly 70, the first detection member 81 and the second detection member 83 cooperate to detect the position of the connecting member 53 relative to the roller brush housing 10, the position of the lifting member 63 relative to the roller brush housing 10, and / or the position of the roller brush 41 of the roller brush assembly 40 relative to the roller brush housing 10. It can be understood that the first detection member 81 and the second detection member 83 in the present embodiment are substantially the same as the first detection member 81 and the second detection member 83 in the above-mentioned embodiments, and will not be repeated here.

[0133] Referring to Figure 2 and Figure 1 In some embodiments, the cleaning device 100 can further comprise a protective cover 91 arranged on the roller brush housing 10 and cooperated with the roller brush housing 10 to form a mounting space in which at least part of the transmission member 23 is located. Thus, the arrangement of the protective cover 91 can prevent water or dust or sand and other impurities from the outside from contacting the transmission member 23, thereby preventing the impurities from the outside from damaging the transmission member 23 and preventing the impurities from causing the transmission member 23 to be stuck, so as to ensure the stability and reliability of the cleaning device 100.

[0134] It should be noted that in some embodiments, the protective cover 91 and the roller brush housing 10 can be combined together by a detachable connection or a non-detachable connection, wherein the detachable connection includes but is not limited to buckle connection or threaded connection, etc.; and the non-detachable connection includes but is not limited to bonding or welding, etc.

[0135] Referring to Figure 2 , Figure 5 , Figure 7 and Figure 7 In some embodiments, the cleaning device 100 further comprises a fan which is in communication with the containing cavity 18. When the fan is running, a negative pressure state can be formed in the containing cavity 18, at this time, the containing cavity 18 and the outside atmospheric pressure have a certain pressure difference, so that the containing cavity 18 has a certain suction force, so as to realize the suction of the garbage on the surface to be cleaned. It can be understood that when the shielding assembly 50 moves to reduce the opening size of the suction inlet 11, the containing cavity 18 more effectively realizes high vacuum degree, thereby effectively improving the cleaning effect of the cleaning device 100.

[0136] 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.

[0137] Please combine Figure 1 In 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.

[0138] 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.

[0139] Please see Figure 7 and Figure 2 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.

[0140] Usually, please combine Figure 1, the cleaning device 100 needs to have a certain gap with the installation housing 230 when installed in the installation housing 230 to prevent interference with the installation housing 230 when the shielding assembly 50 moves. However, in the case that the cleaning device 100 cleans the to-be-cleaned surface, dust or other dirt is likely to enter the gap between the shielding assembly 50 and the installation housing 230, thereby affecting the cleaning effect. For example, in a possible scenario, the dirt in the gap between the shielding assembly 50 and the installation housing 230 is likely to fall onto the cleaned to-be-cleaned surface, affecting the cleaning effect.

[0141] In some embodiments of the present disclosure, the cleaning device 100 further includes a second sealing member 95, which is arranged between the shielding member 51 of the shielding assembly 50 and the installation housing 230, and is configured to seal the gap between the shielding member 51 and the installation housing 230. Thus, the arrangement of the second sealing member 95 can prevent dust and other dirt from the outside from entering the gap between the shielding member 51 and the installation housing 230, thereby ensuring the cleanliness of the cleaning robot and improving the cleaning effect of the cleaning robot. It should be noted that, in some embodiments, the material of the second sealing member 95 includes but is not limited to rubber, silicone, and foam.

[0142] Please refer to Figure 2 , Figure 9 and Figure 1 , the present disclosure provides a cleaning robot 1000, which includes a body 200 and the cleaning device 100 of any of the above embodiments. The cleaning device 100 is arranged on the body 200 and is configured to clean a to-be-cleaned surface.

[0143] In the cleaning robot 1000 of the present disclosure, the cleaning device 100 includes the rolling brush assembly 40, the shielding assembly 50, the lifting assembly 60, and the pressing assembly 70, and the driving assembly 20 is configured to drive the rolling brush assembly 40 to rotate to clean the to-be-cleaned surface, drive the shielding assembly 50 to move to change the opening size of the suction port 11, and drive the lifting assembly 60 or the pressing assembly 70 to move to drive the rolling brush housing 10 to move, thereby driving the rolling brush assembly 40 to ascend or descend relative to the body 200. Thus, compared with the related art, the cleaning device 100 can not only clean the to-be-cleaned surface, but also perform other functions by the rolling brush assembly 40, the shielding assembly 50, the lifting assembly 60, and the pressing assembly 70, thereby improving the applicability of the cleaning robot 1000, meeting the use requirements of users, improving the cleaning effect, such as deep cleaning of a carpet, obstacle crossing, lifting of the rolling brush when entering or leaving a base station, or strong cleaning of stubborn stains. On the other hand, the cleaning functions of different requirements can be realized by one driving assembly, thereby saving cost and reducing the installation space of components, making the overall structure of the cleaning robot compact and achieving miniaturization.

[0144] It can be understood that the specific structure of the cleaning device 100 and the cleaning robot 1000 in the embodiment is completely same as that of the cleaning device 100 and the cleaning robot 1000 in the above embodiment, and no repeated description is made herein.

It can be understood that in some embodiments, the base station 3000 can realize maintenance of the cleaning robot 1000 when the cleaning robot 1000 is located in the parking position of the cleaning robot 1000, and the types of maintenance include but are not limited to charging, dust collection, cleaning and washing of cleaning parts, replenishment of clean water, and sewage extraction. It can be understood that the cleaning robot 1000 can complete at least one of the following in the base station 3000: 1. the base station 3000 charges the cleaning robot 1000; 2. the base station 3000 recycles garbage (for example, garbage in the dust box or sewage tank of the cleaning robot) on the cleaning robot 1000 into its dust collection container; 3. the base station 3000 washes the cleaning parts (for example, washes the mop, cleans the roller brush, and washes the roller) of the cleaning robot 1000; 4. the base station 3000 replenishes clean water to the clean water box of the cleaning robot 1000; 5. the base station 3000 recycles dirt in the sewage tank of the cleaning robot 1000 into its dirt container and discharges to the outside. The above types of maintenance are only exemplary descriptions, and are not limited by the present disclosure.

[0146] It can be understood that the specific structure of the cleaning robot 1000 in the embodiment is completely same as that of the cleaning robot 1000 in the above embodiment, and no repeated description is made herein.

[0147] In the cleaning system 4000 of the embodiment of the present disclosure, the cleaning device 100 comprises the roller brush assembly 40, the shielding assembly 50, the lifting assembly 60, and the pressing assembly 70, and 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 inlet 11, and drive the lifting assembly 60 or the pressing assembly 70 to move to drive the roller brush housing 10 to move, so as to drive the roller brush assembly 40 to ascend or descend relative to the body 200. Therefore, compared with the related art, the cleaning device 100 can not only clean the surface to be cleaned, but also perform other functions by using the roller brush assembly 40, the shielding assembly 50, the lifting assembly 60, and the pressing assembly 70 together, so as to improve the applicability of the cleaning robot 1000 and meet the use requirements of the user.

[0148] It should be noted that the "non-contact" described in the present disclosure can be that the cleaning robot is placed on a relatively flat surface to be cleaned, and is not in contact with the surface to be cleaned. Here, some other states of contact are excluded, that is, the following states of contact cannot be regarded as contact, including but not limited to: the contact of the cleaning robot with the obstacle or the surface to be cleaned caused by the up-down movement of the robot when the robot is climbing over the obstacle; the contact of the cleaning robot with the base surface of the base station caused by the up-down slope when the robot is entering or leaving the base station; the contact caused by the up-down movement of the robot when the robot is walking on the uneven surface to be cleaned; the contact of the cleaning robot with the garbage caused by the relatively large or flying garbage on the surface to be cleaned, or the contact of the cleaning robot with the surface to be cleaned caused by the uneven part of the surface to be cleaned, and the like. For example, when the cleaning robot is placed on a relatively flat surface to be cleaned, the first side is not in contact with the surface to be cleaned, and the second side is in contact with the surface to be cleaned (for example, the first side is inclined relative to the second side, the second side is placed on the surface to be cleaned, and the first side is suspended above the surface to be cleaned); for another example, when the cleaning robot is placed on a relatively flat non-target area, the shielding member is not in contact with the non-target area (for example, the shielding member is suspended above the non-target area); for another example, when the cleaning robot is placed on a relatively flat target area, the shielding member is in contact with the target area (for example, at least part of the shielding member is in contact with the target area).
