Best Mode for Carrying Out the Invention

[0009] Typical embodiments embodying the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can be subject to various changes without departing from the scope of the present disclosure, and the description and the accompanying drawings therein are used essentially for the purpose of explanation and are not intended to limit the present disclosure.

[0010] Different exemplary embodiments of the present disclosure are described as follows with reference to the accompanying drawings, which form a part of the present disclosure and exemplarily show different exemplary structures, systems and steps of multiple aspects capable of implementing the present disclosure. It should be understood that other specific solutions of members, structures, exemplary devices, systems and steps can be used, and structural and functional changes can be made without departing from the scope of the present disclosure. Further, terms such as "above", "between", "inside" etc. are used in this specification to describe different exemplary features and elements of the present disclosure, and these terms are used for convenience in this specification, for example, following the exemplary directions in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional direction of the structure for falling within the scope of the present disclosure.

[0011] As shown in FIGS. 1 to 33, the cleaning system of the embodiment of the present disclosure includes a cleaning robot and a cleaning base station.

[0012] As shown in FIGS. 1 to 29, the cleaning robot includes a main body 20, a dust box 10, a cleaning module 30, a fan assembly 40, a drive system 50, a sensing system, a control module, an energy system and a man-machine interactive system.

[0013] As shown in FIG. 1, the main body 20 includes a front portion 26 and a rear portion 27. The cleaning robot has a generally circular shape (circular both front and rear), and may have other shapes, including but not limited to a generally D-shaped shape with a square front and a circular rear, and a shape with a rectangular or square front and rear. The cleaning operation direction of the cleaning robot can be considered as the direction from the rear portion 27 towards the front portion 26.

[0014] As shown in FIGS. 1 to 3, the sensing system may include a positioning device 21 provided on the main body 20, a collision sensor provided on a buffer 25 of a front portion 26 of the main body 20, a proximity sensor, a cliff sensor provided at a lower portion of the device main body, and a sensing device such as a magnetometer, an accelerometer, a gyroscope, and an odometer provided inside the device main body, and is used to provide various position information and motion state information of the device to the control module. The positioning device 21 includes, but is not limited to, a camera and a laser distance sensor (LDS).

[0015] As shown in FIGS. 1 and 3, a buffer 25 may be mounted on the front portion 26 of the main body 20. During the cleaning process, when the drive system 50 propels the cleaning robot to travel on the floor, the buffer 25 detects one or more events in the travel path of the cleaning robot through a sensor system provided thereon, such as an infrared sensor. The cleaning robot responds to the events detected by the buffer 25, such as obstacles and walls, and controls the drive system 50 so that the cleaning robot responds to the events, for example, moves away from the obstacles.

[0016] The control module is provided on a circuit board within the main body 20 and includes a computing processor that communicates with a NAND non-volatile memory, such as a hard disk, flash memory, and random access memory, for example, a central processing unit, an application processor. The application processor uses a positioning algorithm, such as simultaneous localization and mapping (SLAM), to draw an instant map of the cleaning robot's location environment based on the obstacle information fed back from the laser distance measuring device. Together with the distance information and speed information fed back from the sensing devices such as the sensors provided on the buffer 25, cliff sensors, magnetometers, accelerometers, gyroscopes, and travel distance meters, the control module comprehensively determines the current working state, current position, and current posture of the cleaning robot, such as crossing a threshold, climbing on a carpet, being on a cliff, being caught above or below, the dust box being full, being unable to be lifted, etc., and gives specific next action strategies according to different situations, so that the cleaning performance and user experience of the cleaning robot are better.

[0017] As shown in FIGS. 3 and 4, the drive system 50 can steer the main body 20 to travel on the floor surface based on drive commands having distance and angle information (e.g., x, y, and θ components). The drive system 50 includes a first drive wheel module 51 and a second drive wheel module 52. The first drive wheel module 51 and the second drive wheel module 52 are provided along the horizontal axis defined by the main body 20. In order for the cleaning robot to move more stably on the floor surface or have stronger movement ability, the cleaning robot may include one or more driven wheels 53, and the driven wheels include, but are not limited to, universal wheels. The drive wheel module includes a traveling wheel, a drive motor, and a control circuit for controlling the drive motor, and a circuit for measuring the drive current and an odometer may be further connected to the drive wheel module. The drive wheel module may be detachably attached to the main body 20 for easy detachment and maintenance. The drive wheels may have a biased drop suspension system, be movably fixed, for example, rotatably attached to the main body 20, and receive a spring bias biased downward away from the main body 20. The spring bias enables the drive wheels to maintain contact and traction with the floor surface with a certain ground contact force, and at the same time enables the cleaning elements of the cleaning robot to contact the floor surface with a certain pressure.

[0018] The main body 20 defines a horizontal axis and a vertical axis, the horizontal axis and the vertical axis are perpendicular to each other, and the horizontal axis and the vertical axis are understood as the horizontal center line and the vertical center line of the main body 20, respectively.

[0019] The energy system includes rechargeable batteries such as nickel-metal hydride batteries and lithium batteries. A charge control circuit, a battery pack charging temperature detection circuit, and a battery voltage shortage monitoring circuit may be connected to the rechargeable battery, and the charge control circuit, the battery pack charging temperature detection circuit, and the battery voltage shortage monitoring circuit are connected to the microcomputer control circuit. The host computer is connected to the charging pile for charging through charging electrodes provided on the side or below the main body.

[0020] The man-machine interactive system includes buttons on the host computer panel. The buttons are used for the user to make function selections and may further include a display screen and / or an indicator lamp and / or a speaker. The display screen, indicator lamp and speaker are used to display the current state of the device or function options to the user, and may further include a mobile phone client program. In the case of a path navigation type automatic cleaning device, the mobile phone client can display a map of the device's location environment and the location of the device to the user, and provide richer and more user-friendly function items to the user.

[0021] In the cleaning robot according to the embodiment of the present disclosure, the dust box 10 is provided on the main body 20, and at least a part of the positioning device 21 protrudes from the main body 20. Since the top end of the dust box 10 is not lower than at least a part of the top end of the main body 20, and the top end of the positioning device 21 is higher than the top end of the dust box 10, after setting the height of the dust box 10 to be as high as possible, it can be ensured that the positioning device 21 triggers an obstacle first, thereby indirectly protecting the dust box 10 or the main body 20 from being caught by the obstacle.

[0022] In addition, since the top end of the dust box 10 is not lower than at least a part of the top end of the main body 20, compared with the height of the main body of the cleaning robot in the related art, without changing the original height of the main body, the height of the dust box 10 can be set as high as possible, thereby improving the dust collection capacity of the dust box 10 without increasing the height of the cleaning robot.

[0023] In an embodiment of the present disclosure, as shown in FIGS. 1 and 2, the main body 20 has a top main surface 22, at least a part of the positioning device 21 is provided to protrude from the top main surface 22, and the top end of the dust box 10 is higher than the top main surface 22. The top main surface 22 is a large surface on the upper part of the cleaning robot. By providing at least a part of the positioning device 21 to protrude from the top main surface 22, it is ensured that the positioning device 21 can accurately identify obstacles. By the top end of the dust box 10 being higher than the top main surface 22, it is ensured that the dust box 10 has sufficient dust collection capacity.

[0024] In an embodiment of the present disclosure, as shown in FIGS. 1 and 2, the main body 20 further has a top protruding surface 23, the top protruding surface 23 is higher than the top main surface 22 and lower than the top end of the positioning device 21. Here, at least a part of the dust box 10 is located below the top protruding surface 23. The top protruding surface 23 is a small surface on the upper part of the cleaning robot. By the top end of the positioning device 21 being higher than the top protruding surface 23, it is ensured that the positioning device 21 can accurately identify obstacles. By at least a part of the dust box 10 being located below the top protruding surface 23, it is prevented that the height size of the cleaning robot is too high due to the dust box 10, and the main body 20 also plays a role in protecting the dust box 10.

[0025] In an embodiment of the present disclosure, as shown in FIGS. 1 and 2, the main body 20 further has a transition surface 24, the transition surface 24 connects the top main surface 22 and the top protruding surface 23. Here, the top main surface 22 is substantially parallel to the top protruding surface 23, and the transition surface 24 is inclined with respect to the top protruding surface 23. It not only has a more aesthetic appearance design, but also facilitates the main body 20 to pass through low obstacles and avoids the cleaning robot from being caught. Specifically, the transition surface 24 can effectively avoid the cleaning robot from being caught by an obstacle having a height between the top end of the positioning device 21 and the top main surface 22.

[0026] In an embodiment of the present disclosure, a part of the dust box 10 is located below the top main surface 22, and a part of the dust box 10 is located below the top protruding surface 23. Thereby, the height of a part of the dust box 10 becomes higher, other structures can be conveniently arranged, or the local dust collection space can even be increased, and other parts of the dust box 10 can be adjusted to the height of the main body of the cleaning robot. The main body 20 can effectively protect the dust box 10 and avoid problems such as damage to the dust box 10.

[0027] As an alternative embodiment of the present disclosure, the top end of the positioning device 21 is 0.2 mm to 10 mm higher than the top end of the dust box 10, thereby ensuring that the positioning device 21 can trigger an obstacle first, and the height of the dust box 10 can be relatively high, which contributes to the improvement of the dust collection ability.

[0028] In an embodiment of the present disclosure, along the cleaning operation direction of the cleaning robot, the dust box 10 is arranged behind the positioning device 21. The positioning device 21 is arranged at the middle position of the cleaning robot, the dust box 10 is arranged behind the cleaning robot, and the vertical projections of the positioning device 21 and the dust box 10 may not have an overlapping area. The height of at least a part of the dust box 10 can be made larger than the top main surface 22, and the height of the dust box 10 can be further ensured without considering the interference between the positioning device 21 and the dust box 10.

[0029] The embodiment of the present disclosure provides a cleaning robot that cooperates with a cleaning base station and discharges internal dust to the cleaning base station. The cleaning robot includes a dust storage chamber 11 having an opening, and a door body 12 that is movably provided with respect to the dust storage chamber 11 and opens and closes the opening. Here, after the cleaning robot is aligned with the cleaning base station, the door body 12 can open the opening and communicate the opening with the dust inlet of the cleaning base station.

[0030] In the cleaning robot according to an embodiment of the present disclosure, a door body 12 is provided at the opening of the dust storage chamber 11. The door body 12 is provided movably with respect to the dust storage chamber 11. After the cleaning robot is aligned with the cleaning base station, the door body 12 opens the opening, communicates the opening with the dust inlet of the cleaning base station, discharges the dust in the dust storage chamber 11 to the cleaning base station, improves the dust discharge efficiency of the cleaning robot, and can improve the use performance of the cleaning robot.

[0031] The dust storage chamber 11 according to an embodiment of the present disclosure may be formed by the main body 20. That is, a cavity is formed inside the main body 20. This cavity collects dust and is used as the dust storage chamber 11. By providing the door body 12 on the main body 20, the opening of the dust storage chamber 11 can be closed to avoid dust leakage. When discharging the dust in the dust storage chamber 11, the door body 12 is opened to open the opening of the dust storage chamber 11 and discharge the dust in the dust storage chamber 11. For example, the dust in the dust storage chamber 11 can be discharged to the cleaning base station.

[0032] The dust storage chamber 11 according to an embodiment of the present disclosure may be formed by a dust box 10 on the main body 20. The dust box 10 is provided on the main body 20. The dust box 10 and the main body 20 form the robot main body. By providing the door body 12 on the dust box 10, the opening of the dust storage chamber 11 can be opened and closed.

[0033] The dust box 10 provided according to an embodiment of the present disclosure includes a dust storage chamber 11. The dust storage chamber 11 includes a first cavity 111 having a dust inlet 1112, a second cavity 112 having an air outlet 1123, and a transfer passage 113. The first cavity 111 communicates with the second cavity 112 through the transfer passage 113.

[0034] Referring also to FIGS. 7 to 16, the dust box 10 of the embodiment of the present disclosure includes a separately provided first cavity 111 and a second cavity 112. The first cavity 111 communicates with the second cavity 112 through a transfer passage 113, achieving initial separation of dust in the first cavity 111, thereby reducing the probability of dust clogging the transfer passage 113, ensuring dust collection, and improving the dust collection ability of the dust box 10.

[0035] The dust entering from the cleaning module 30 enters the first cavity 111 through the dust inlet 1112 for initial separation, and then enters the second cavity 112 through the transfer passage 113, thereby realizing effective recovery of dust. The filtered gas is discharged into the dust box 10 through the air outlet 1123.

[0036] In the embodiment of the present disclosure, the transfer passage 113 is substantially in contact with the second cavity 112, so that dust can surely enter the second cavity 112 from the transfer passage 113, which is beneficial to the flow of gas, thereby improving the fluidity of dust in the dust storage chamber 11 and improving the dust collection ability of the dust box 10.

[0037] As an alternative embodiment of the present disclosure, the transfer passage 113 is substantially in contact with the first cavity 111, so that dust can surely enter the transfer passage 113 from the first cavity 111, which is beneficial to the flow of gas, thereby improving the fluidity of dust in the dust storage chamber 11.

[0038] A cyclone separator 13 is provided in the second cavity 112. The gas entering in contact with the second cavity 112 passes through the cyclone separator 13 to separate fine dust and gas, ensuring the cleanliness of the screen. The cyclone separator 13 may be a conical tube for cyclone separation.

[0039] In the embodiment of the present disclosure, the side wall of the transfer passage 113 includes a curved surface, so that dust can flow smoothly in the transfer passage 113, thereby avoiding problems such as dust clogging.

[0040] In an embodiment of the present disclosure, the extension length of the transfer passage 113 is greater than the minimum wall thickness between the first cavity 111 and the second cavity 112, thereby enabling the airflow to carry dust through the transfer passage 113 for a longer time, and thereby avoiding problems such as blockage of the transfer passage 113 caused by the accumulation of a large amount of dust.

[0041] Note that the extension length of the transfer passage 113 is considered to be the distance of the airflow flowing in the transfer passage 113. Since the first cavity 111 and the second cavity 112 are separated by the wall surface of the dust box 10, the extension length of the transfer passage 113 being greater than the minimum wall thickness between the first cavity 111 and the second cavity 112 can avoid the problem of blockage of the transfer passage 113 due to the accumulation of dust.

[0042] In an embodiment of the present disclosure, the door body 12 is rotatably provided on the dust box 10, so that the door body 12 can easily open and close the opening of the dust storage chamber 11.

[0043] A drive mechanism may be connected to the door body 12 to drive the door body 12 to rotate with respect to the dust box 10. Alternatively, after the cleaning robot is combined with the cleaning base station, the opening and closing of the door body 12 may be driven by using the airflow generated by the fan assembly 40 of the cleaning robot. Alternatively, after the cleaning robot is combined with the cleaning base station, the opening and closing of the door body 12 may be driven by using the suction force generated by the power assembly of the cleaning base station.

[0044] As an alternative embodiment of the present disclosure, the door body 12 is movably provided with respect to the dust box 10. The door body 12 is driven by a drive mechanism to achieve the horizontal movement of the door body 12. For example, the drive mechanism may be an electric push rod, and the electric push rod drives the door body 12 to move horizontally with respect to the dust box 10.

[0045] In an embodiment of the present disclosure, at least a part of the dust box 10 is located outside the main body 20. When the door body 12 opens the opening, the opening directly communicates with the dust inlet, so that the dust in the dust box 10 can be easily discharged into the cleaning base station.

[0046] After the door body 12 opens the opening, a part of the door body 12 extends inside the dust inlet and can be stored. Therefore, the opening of the dust storage chamber 11 and the dust inlet are reliably docked, ensuring that dust is effectively collected into the cleaning base station.

[0047] Since the dust box 10 and the main body 20 form at least a part of the outer surface of the cleaning robot, after the cleaning robot and the cleaning base station are combined, by directly aligning the dust box 10 with the cleaning base station, after the door body 12 is opened, the opening of the dust storage chamber 11 is reliably aligned with the dust inlet.

[0048] In an embodiment of the present disclosure, as shown in FIGS. 11 to 13, the dust storage chamber 11 includes a first cavity 111 and a second cavity 112. The door body 12 selectively opens the first cavity 111 and the second cavity 112, so that the first cavity 111 and the second cavity 112 selectively communicate with the dust inlet. Therefore, the dust in the dust storage chamber 11 can be discharged step by step, avoiding problems such as clogging when a large amount of dust is discharged, and improving the dust collection efficiency.

[0049] The first cavity 111 and the second cavity 112 are provided independently. Dust may be stored in both the first cavity 111 and the second cavity 112, but the dust in the first cavity 111 and the second cavity 112 may be dust at different stages. For example, during the cleaning process of the cleaning robot, dust first enters the first cavity 111, and then some dust enters the second cavity 112. Therefore, the sizes of the dust in the first cavity 111 and the second cavity 112 may not be the same.

[0050] As an optional embodiment of the present disclosure, there may be one door body 12, and the door body 12 may be movably provided with respect to the dust box 10, whereby the door body 12 can selectively open the first cavity 111 and the second cavity 112.

[0051] In an embodiment of the present disclosure, as shown in FIGS. 8 and 9, the door body 12 includes a first door body member 121 and a second door body member 122. The first door body member 121 and the second door body member 122 are separated from each other. The first door body member 121 and the second door body member 122 respectively correspond to the first cavity 111 and the second cavity 112. By opening the first door body member 121 and the second door body member 122 respectively, the first cavity 111 and the second cavity 112 can be easily opened.

[0052] The first door body member 121 and the second door body member 122 are respectively rotatably provided on the dust box 10. By controlling the opening of the first door body member 121 and the second door body member 122 respectively, the opening of the first cavity 111 and the second cavity 112 can be controlled respectively. For example, by driving the operation of the first door body member 121 and the second door body member 122 by two different driving mechanisms, the opening time of the first door body member 121 and the second door body member 122 can be controlled.

[0053] In an embodiment of the present disclosure, as shown in FIG. 12, the dust box 10 further includes a cyclone separator 13, and the cyclone separator 13 is provided in the second cavity 112. It should be noted that the cyclone separator 13 may be a known cyclone separator in related art. The working principle of the cyclone separator is that when the particles rotate at a high speed in the airflow due to the tangential airflow introduction, the centrifugal force is much larger than the gravity, and the higher the speed, the greater the centrifugal sedimentation speed of the particles. When the solid particles enter the conical cylinder from the tangential direction together with the gas and rotate in the cylinder, the airflow collides with the tube wall, and the particles collide with the tube wall and descend while rotating, thereby achieving the purpose of separating the solid and the gas.

[0054] As shown in FIGS. 18 and 19, the cyclone separator 13 is composed of a primary separation cyclone 131 and a secondary separation cyclone 132. The secondary separation cyclone 132 includes a plurality of cyclone separators. The cyclone separator body is conical with a large upper end and a small lower end, and is distributed around the axis of the secondary separation cyclone 132 respectively. By installing a plurality of sets of cyclone separators, the dust separation efficiency of the secondary separation cyclone can be improved, and the dust collection capacity of the cleaning base station can be further improved. The number of secondary cyclone separators may be 9, 12, or 15. The higher the number, the higher the separation efficiency.

[0055] The outer periphery of the secondary separation cyclone 132 is a separation screen 133. Together with the outer surface of the primary separation cyclone 131, the inner surface of the dust box 10, and the outer surface of the separation screen 133, a primary cyclone is formed. After the air is separated by the primary cyclone, large particle dust is separated from the air flow and falls outside the primary separation cyclone 131. The separation screen 133 is used to allow the air flow that enters the secondary separation cyclone 132 after being separated by the primary cyclone to pass through. The separation screen 133 is preferably a metal filter, which can extend the service life and improve the filtration effect. The separation screen 133 is an annular mesh. The support rack of the primary separation cyclone 131 is used to support the bottom of the separation screen 133. The particulate dust filtered by the separation screen 133 is collected below the support rack of the primary separation cyclone 131. The outer edge of the support rack of the primary separation cyclone 131 extends downward to form a skirt shape, which can prevent the particulate dust separated by the primary cyclone from moving to the outside. Each secondary separation cyclone 132 forms one gas-solid separation cyclone, and the separated solid particle dust falls inside the primary separation cyclone 131.

[0056] In an embodiment of the present disclosure, as shown in FIGS. 9 to 11, the first cavity 111 has a first opening 1111, the second cavity 112 has a second opening 1121 and a third opening 1122 separated from each other, the second opening 1121 communicates with a portion of the second cavity 112 disposed outside the cyclone separator 13, the third opening 1122 communicates with a portion of the second cavity 112 disposed inside the cyclone separator 13. Here, the first door member 121 opens and closes the first opening 1111, and the second door member 122 opens and closes the second opening 1121 and the third opening 1122 simultaneously.

[0057] Dust enters the second cavity 112 from the first cavity 111, and the dust that has passed through the cyclone separator 13 falls inside the primary separation cyclone 131. After the first door member 121 opens the first opening 1111, the dust in the first cavity 111 can be discharged. By simultaneously opening the second opening 1121 and the third opening 1122, the second door member 122 can discharge the dust in the second cavity 112. That is, the dust that has fallen outside the primary separation cyclone 131 and the dust that has fallen inside the primary separation cyclone 131 can be discharged through the second opening 1121 and the third opening 1122, respectively. The dust may include solid waste. The primary separation cyclone 131 separates coarse particles, and the secondary separation cyclone 132 separates fine particles, thereby ensuring the separation effect of the cyclone separator 13.

[0058] In an embodiment of the present disclosure, the dust storage chamber 11 includes a first cavity 111 and a second cavity 112. The first cavity 111 and the second cavity 112 have a first opening 1111 and a second opening 1121, respectively. The door body 12 includes a first door member 121 and a second door member 122. The first door member 121 and the second door member 122 correspond to the first opening 1111 and the second opening 1121, respectively. By opening and closing the first opening 1111 and the second opening 1121, after the cleaning robot is combined with the cleaning base station, the first door member 121 and the second door member 122 open the first opening 1111 and / or the second opening 1121 to communicate the first opening 1111 and / or the second opening 1121 with the dust inlet of the cleaning base station, so that the dust in the dust storage chamber 11 can be discharged to the cleaning base station.

[0059] In an embodiment of the present disclosure, the dust storage chamber 11 includes a first cavity 111 and a second cavity 112. The first cavity 111 and the second cavity 112 each have a first opening 1111 and a second opening 1121 respectively. The door body 12 includes a first door body member 121 and a second door body member 122. The first door body member 121 and the second door body member 122 correspond to the first opening 1111 and the second opening 1121 respectively. By opening and closing the first opening 1111 and the second opening 1121, when the cleaning robot is separated from the cleaning base station, the first door body member 121 and the second door body member 122 can close the first opening 1111 and the second opening 1121, thereby avoiding dust from flowing out of the dust storage chamber 11. For example, during the cleaning process of the cleaning robot, it is necessary for the first door body member 121 and the second door body member 122 to close the first opening 1111 and the second opening 1121.

[0060] In an embodiment of the present disclosure, the area of the first opening 1111 may be larger than the area of the second opening 1121, and the area of the second opening 1121 may be larger than the area of the third opening 1122.

[0061] As an alternative embodiment of the present disclosure, the area of the first opening 1111 may be greater than or equal to the area of the second opening 1121, and the area of the second opening 1121 may be less than or equal to the area of the third opening 1122.

[0062] In an embodiment of the present disclosure, as shown in FIGS. 7 and 8, the dust box 10 further includes a base 14 and a bottom cover 15 provided on the base 14. The bottom cover 15 and the base 14 form the first cavity 111 and the second cavity 112. The door body 12 is movably provided on the bottom cover 15 to open and close the first cavity 111 and the second cavity 112.

[0063] At least one of the base 14 and the bottom cover 15 is connected to the main body 20, so that a fixed connection between the dust box 10 and the main body 20 is realized. The bottom cover 15 forms a part of the outer surface of the bottom of the cleaning robot. The base 14 and the bottom cover 15 form a closed first cavity 111 and a second cavity 112. The transfer passage 113 is formed inside the base 14 and is used to communicate the first cavity 111 and the second cavity 112.

[0064] At least one of the base 14 and the bottom cover 15 is connected to the main body 20. Here, at least a part of the base 14 and the bottom cover 15 form a part of the outer surface of the cleaning robot, and together with the main body 20, form at least a part of the outer surface of the cleaning robot.

[0065] The base 14 may have an integral structure, that is, the bottom opening of the base 14 may be closed by the bottom cover 15. Alternatively, the base 14 may include a main body structure and a top cover. The top cover is provided opposite to the bottom cover 15, and the top cover and the bottom cover 15 may respectively close the top opening and the bottom opening of the base 14.

[0066] As shown in FIGS. 8 to 11, by providing a first opening 1111, a second opening 1121, and a third opening 1122 in the bottom cover 15, the first door body member 121 can open and close the first opening 1111, and the second door body member 122 can simultaneously open and close the second opening 1121 and the third opening 1122.

[0067] In an embodiment of the present disclosure, the first door body member 121 and the second door body member 122 are rotatably provided on the bottom cover 15. For example, when the cleaning robot returns to the cleaning base station and the door body 12 is aligned with the dust inlet of the cleaning base station, the first door body member 121 and / or the second door body member 122 can rotate relative to the bottom cover 15 to open the first opening 1111 and / or the second opening 1121 and the third opening 1122.

[0068] In an embodiment of the present disclosure, the bottom cover 15 is detachably provided on the base 14, so that the inside of the base 14 can be cleaned or maintained. After the bottom cover 15 is removed from the base 14, the internal space of the base 14 is opened, so that dust can be cleaned, the members inside the base 14 can be maintained and cleaned. For example, the cyclone separator 13 in the second cavity 112 can be maintained.

[0069] The bottom cover 15 may be locked to the base 14. The bottom cover 15 may be connected to the base 14 by a structural member.

[0070] In an embodiment of the present disclosure, as shown in FIGS. 7 and 17, the dust box further includes a locking member 16. The locking member 16 is provided on the base 14 and is movably provided with respect to the bottom cover 15. By moving away from or connecting to the bottom cover 15, fixing or opening of the bottom cover 15 is achieved.

[0071] As shown in FIG. 17, the locking member 16 includes a toggle portion 161, a first locking portion 162 and a second locking portion 163. Both sides of the toggle portion 161 are respectively connected to the first locking portion 162 and the second locking portion 163. The toggle portion 161 is movably provided on the base 14, and a part of the toggle portion 161 is exposed outside the base 14, so that the toggle portion 161 drives the first locking portion 162 and the second locking portion 163 to move with respect to the bottom cover 15. When the first locking portion 162 and the second locking portion 163 are connected to the bottom cover 15, the bottom cover 15 is fixed on the base 14. When the first locking portion 162 and the second locking portion 163 are disengaged from the bottom cover 15, the bottom cover 15 is removed from the base 14.

[0072] It should be noted that the bottom cover 15 may be removed from the base 14 as a whole, or the bottom cover 15 may be hinged to the base 14. After the first locking portion 162 and the second locking portion 163 are disengaged from the bottom cover 15, the bottom cover 15 can rotate with respect to the base 14, so that the bottom cover 15 can open the internal space of the base 14.

[0073] In an embodiment of the present disclosure, the dust box 10 is detachably provided on the main body 20, so that the dust box 10 can be easily cleaned or maintained.

[0074] Since at least a part of the dust box 10 is located outside the main body 20, not only can the attachment and detachment of the dust box 10 be facilitated, but also the specific structure of the dust box 10 can be adaptively adjusted, the dust box 10 can be easily installed, and the maximum dust collection capacity of the dust box 10 can be satisfied.

[0075] In an embodiment of the present disclosure, as shown in FIGS. 7 and 8, a retraction space 141 is provided on the base 14, and the retraction space 141 is provided adjacent to the bottom cover 15, so as to avoid the hand rest space and prevent direct contact of the hand with the bottom cover 15, and the operation during the attachment or detachment of the dust box 10 can be facilitated.

[0076] In an embodiment of the present disclosure, as shown in FIG. 10, a rolling part 151 is provided on the bottom cover 15, so as to prevent excessive wear of the bottom cover 15, and the rolling part 151 can reduce the contact resistance between the bottom cover 15 and the floor surface or the cleaning base station. The rolling part 151 is rotatably provided on the bottom cover 15. Here, since the bottom end of the rolling part 151 protrudes from the bottom surface of the bottom cover 15, the rolling part 151 can form contact with the floor surface or the cleaning base station and reduce the contact resistance.

[0077] The rolling part 151 may be a roller, and the rolling part 151 may be one or more.

[0078] As an alternative embodiment of the present disclosure, the bottom cover 15 may be fixed on the base 14, and further, the bottom cover 15 is non-removable from the base 14.

[0079] As an alternative embodiment of the present disclosure, the dust box 10 may be fixed on the main body 20, and further, the dust box 10 may be non-removable from the main body 20.

[0080] As an alternative embodiment of the present disclosure, the dust box 10 may be disposed entirely inside the main body 20.

[0081] In the cleaning robot provided by the embodiment of the present disclosure, the cleaning module 30 is provided on the main body 20, and the cleaning module 30 realizes the cleaning of the surface to be cleaned.

[0082] In an embodiment of the present disclosure, the cleaning module 30 may be a dry cleaning module, and the dry cleaning system may include a roller brush. The roller brush having a certain interference with the floor surface sweeps up the dust on the floor surface and rolls it up in front of the dust inlet 1112 between the roller brush and the dust box 10, and then is sucked into the dust box 10 by the gas generated by the fan assembly 40 and having a suction force passing through the dust box 10. The dust removal ability of the cleaning robot is characterized by the dust cleaning efficiency (DPU, Dust pickup efficiency). The cleaning efficiency DPU is affected by the roller brush structure and material, and is affected by the wind utilization rate of the air duct composed of the dust inlet 1112, the dust box 10, the fan 41, the air outlet and the connecting members among the four, and is affected by the type and power of the fan, which is a problem in complex system design. Compared with ordinary plug-in vacuum cleaners, the improvement of the dust removal ability has great significance for the energy-limited cleaning automatic cleaning device. The improvement of the dust removal ability can directly reduce the energy requirement. That is, a device that can clean a floor area of 80 square meters with one charge can be evolved to be able to clean a floor area of more than 180 square meters with one charge. In addition, by reducing the number of charges, the service life of the battery is greatly extended, and the frequency of battery replacement by the user is also reduced. More intuitively and importantly, the improvement of the dust removal ability is the most obvious and important user experience, and the user can directly conclude whether the cleaning / wiping is clean. The cleaning robot may further include a side brush 37 having a rotating shaft, and the rotating shaft forms a certain angle with the floor surface to move the dust to the roller brush area of the cleaning system.

[0083] As an optional embodiment of the present disclosure, the cleaning module 30 may be a wet cleaning module. The wet cleaning module may include a wet cleaning head. The cleaning module 30 may further include a liquid supply unit. The liquid supply unit sends cleaning liquid to the wet cleaning head, and the wet cleaning head wet-cleans the plane to be cleaned. In other embodiments of the present disclosure, the cleaning liquid inside the liquid supply unit may be directly sprayed onto the plane to be cleaned, and the wet cleaning head achieves the cleaning of the plane by spreading the cleaning liquid evenly. Exemplarily, the wet cleaning module can be assembled and applied to other types of cleaning devices, but it is not particularly limited in the present disclosure.

[0084] Here, the cleaning head is used to clean the surface to be cleaned, and the drive system 50 is used to drive the cleaning head to basically reciprocate along the target surface. The target surface is a part of the surface to be cleaned. The cleaning head reciprocates along the surface to be cleaned, and a cleaning cloth or a cleaning plate is provided on the contact surface between the cleaning head and the surface to be cleaned, generating high-frequency friction with the surface to be cleaned by the reciprocating movement, thereby removing the dirt on the surface to be cleaned. The cleaning head may be a mopping roller brush.

[0085] The higher the friction frequency, the more friction times per unit time. The high-frequency reciprocating movement is also called reciprocating vibration. The cleaning ability is much higher than that of normal reciprocating movement, such as rotation and friction cleaning. Optionally, the friction frequency is close to that of sound waves, and the cleaning effect is much greater than that of rotational friction cleaning at dozens of revolutions per minute. In another aspect, since the clusters of hairs on the surface of the cleaning head extend in the same direction more neatly under the sway of high-frequency vibration, the overall cleaning effect is not to improve the cleaning effect by simply increasing the strong pressing friction force in the case of low-frequency rotation, but is more uniform. Even with strong pressing alone, multiple sets of hair clusters do not extend in almost the same direction. Effectively, the water marks on the surface to be cleaned after being cleaned by high-frequency vibration become more uniform without being chaotic.

[0086] The reciprocating movement may be a reciprocating motion along any one or more directions within the surface to be cleaned, or may be a vibration perpendicular to the surface to be cleaned, but is not strictly limited. Optionally, the reciprocating movement direction of the cleaning module is substantially perpendicular to the device traveling direction. This is because a reciprocating movement direction parallel to the device traveling direction will cause instability to the device itself during traveling. The driving wheels are prone to slipping due to the thrust and resistance in the traveling direction. When a wet cleaning module is provided, the slipping effect is more prominent. The wetness of the surface to be cleaned increases the slipping risk. Slipping not only affects the stable traveling and cleaning of the device, but also makes the measurements of sensors such as the odometer and gyroscope inaccurate, preventing the navigation-type automatic cleaning device from accurately positioning and mapping. In the case of frequent slipping, the impact on SLAM cannot be ignored, so it is necessary to avoid the slipping movement of the device as much as possible. In addition to slipping, due to the cleaning head movement component in the device traveling direction, the device will receive forward and backward driving forces while traveling, so the traveling of the device will be irregular and smooth at one time.

[0087] As shown in FIGS. 4 to 6, in the cleaning robot according to the embodiment of the present disclosure, at least a part of the cleaning module 30 is provided to be vertically movable relative to the main body 20. The dust box 10 communicates with the cleaning module 30. The cyclone separator 13 is provided in the dust box 10. By communicating the fan assembly 40 with the dust box 10, the cleaning module 30 can surely clean the surface to be cleaned. At least a part of the cleaning module 30 is provided to be vertically movable relative to the main body 20. By installing the cyclone separator 13, during the cleaning process of the cleaning robot, the current can be prevented from being too high, and the cleaning time of the cleaning robot can be prolonged.

[0088] Note that the cyclone separator 13 has a large air volume and a high negative pressure. When the cleaning robot cleans the carpet, at least a part of the cleaning module 30 is provided so as to be movable up and down with respect to the main body 20, thereby reducing the current of the cleaning module 30, reducing the burden on the cleaning module 30, and enabling the cleaning robot to clean the carpet more durably.

[0089] In the embodiments of the present disclosure, the cleaning robot further includes a lifting structure. The lifting structure is connected to the cleaning module 30 and is configured to move at least a part of the cleaning module 30 up and down with respect to the main body 20. Actually, the lifting structure is independently connected to the cleaning module 30, and the cleaning module 30 is moved up and down with respect to the main body 20. An additional power device may be added to the lifting structure to give the lifting structure the ability to actively lift and lower, so that at least a part of the cleaning module 30 can actively move up and down with respect to the main body 20.

[0090] As an alternative embodiment of the present disclosure, the lifting structure may be an elastic assembly, and at least a part of the cleaning module 30 can actively move up and down.

[0091] In the embodiments of the present disclosure, as shown in FIGS. 20A and 21, the cleaning module 30 includes a cleaning cover 31 and a roller brush provided in the cleaning cover 31. Here, the lifting structure is connected to the cleaning cover 31 and can drive the roller brush to move up and down, so that the roller brush can clean the surface to be cleaned and adapt to different surfaces to be cleaned.

[0092] The lifting structure is connected to the main body 20, the lifting structure is connected to the cleaning cover 31, and the roller brush is connected to the cleaning cover 31. Thus, the lifting structure can drive the roller brush to move up and down with respect to the main body 20 via the cleaning cover 31.

[0093] In an embodiment of the present disclosure, as shown in FIGS. 20D and 20E, the lifting structure includes a first connection assembly 60 with both ends connected to the main body 20 and the cleaning cover 31 respectively, and a second connection assembly 70 provided at an interval from the first connection assembly 60 with both ends connected to the main body 20 and the cleaning cover 31 respectively. The first connection assembly 60 and the second connection assembly 70 can firmly connect the cleaning cover 31 onto the main body 20, and when the cleaning module 30 is pushed under its own weight and there are unevenness on the surface to be cleaned, the cleaning module 30 can be lifted up and down, thereby ensuring the cleaning performance of the cleaning module 30.

[0094] In an embodiment of the present disclosure, as shown in FIGS. 20D and 20E, the first connection assembly 60 includes a first connecting rod 61 and a second connecting rod 62. The first connecting rod 61 and the second connecting rod 62 are parallel to each other. Both ends of the first connecting rod 61 and the second connecting rod 62 are hingedly connected to the main body 20 and the cleaning cover 31 respectively. The second connection assembly 70 includes a third connecting rod 71 and a fourth connecting rod 72. The third connecting rod 71 and the fourth connecting rod 72 are parallel to each other. Both ends of the third connecting rod 71 and the fourth connecting rod 72 are hingedly connected to the main body 20 and the cleaning cover 31 respectively. Here, the first connecting rod 61 and the third connecting rod 71 are parallel to each other. The lifting structure is a four-link mechanism. With the four-link mechanism, not only can the cleaning module 30 be lifted up and down to ensure the cleaning performance of the cleaning module 30, but also the limitation of the degree of freedom of the cleaning module 30 can be realized, and the cleaning module 30 can be made to operate according to requirements.

[0095] In an embodiment of the present disclosure, as shown in FIG. 20D, a protection cover 28 may be provided on the main body 20. The cleaning module 30 is provided inside the protection cover 28, and the first connection assembly 60 and the second connection assembly 70 are connected on the protection cover 28. The protection cover 28 is detachably connected to the main body 20.

[0096] As a selectable embodiment of the present disclosure, the lifting structure is connected to the main body 20, and the lifting structure is connected to the roller brush, so that the lifting structure can drive the roller brush to move up and down, that is, the roller brush can move up and down with respect to the cleaning cover 31. At this time, the cleaning cover 31 can be fixedly connected to the main body 20. Alternatively, the cleaning cover 31 is fixedly connected to the main body 20, the lifting structure is connected to the cleaning cover 31, and the lifting structure is connected to the roller brush, so that the lifting structure can drive the roller brush to move up and down, that is, the roller brush can move up and down with respect to the cleaning cover 31.

[0097] The lifting structure includes a first connection assembly 60 with both ends respectively connected to the roller brush and the cleaning cover 31, and a second connection assembly 70 provided at an interval from the first connection assembly 60 with both ends respectively connected to the roller brush and the cleaning cover 31. Here, the cleaning cover 31 is fixedly connected to the main body 20. The first connection assembly 60 and the second connection assembly 70 securely connect the roller brush onto the cleaning cover 31. When the roller brush is pushed under its own weight and there are unevenness on the surface to be cleaned, the roller brush can move up and down, thereby ensuring the cleaning performance of the cleaning module 30.

[0098] The first connection assembly 60 is connected to the roller brush via the driving structure 36, and the second connection assembly 70 is connected to the roller brush via the driving structure 36, that is, both the first connection assembly 60 and the second connection assembly 70 are connected to the driving structure 36, and the driving structure 36 is connected to the roller brush. When the roller brush and the driving structure 36 are pushed under their own weight and there are unevenness on the surface to be cleaned, the roller brush can move up and down, thereby ensuring the cleaning performance of the cleaning module 30.

[0099] The first connection assembly 60 and the second connection assembly 70 in this embodiment are the same as the structures shown in FIGS. 20D and 20E except that the connection positions are different.

[0100] In an embodiment of the present disclosure, the roller brush realizes the cleaning of the surface to be cleaned by rotation. The cyclone separator 13 has a large air volume and a high negative pressure. When the cleaning robot cleans the carpet, at least a part of the cleaning module 30 is provided to be movable up and down with respect to the main body 20, so that the driving current of the roller brush can be reduced, the driving burden of the roller brush can be reduced, and the cleaning robot can clean the carpet more durably.

[0101] In an embodiment of the present disclosure, as shown in FIGS. 21, 24, and 25, the cleaning module 30 further includes a driving structure 36. The driving structure 36 includes a power part 361 and a transmission assembly. The power part 361 drives the roller brush to rotate through the transmission assembly, so that the surface to be cleaned can be surely cleaned.

[0102] In an embodiment of the present disclosure, there are a plurality of roller brushes. The power part 361 drives the plurality of roller brushes to rotate synchronously through the transmission assembly, so as to reduce the installation of the power part 361, but ensure the synchronous cleaning of the plurality of roller brushes, thereby improving the cleaning ability of the cleaning robot.

[0103] In an embodiment of the present disclosure, as shown in FIGS. 20A, 22, and 23, the cleaning cover 31 has a mounting chamber 311, and the mounting chamber 311 may include a main air duct 3111 and a sub-air duct 3112.

[0104] As shown in FIGS. 22 and 23, in the cleaning robot according to the embodiment of the present disclosure, the cleaning cover 31 includes a main air duct 3111 and a sub-air duct 3112. The sub-air duct 3112 communicates with the dust storage chamber 11. The roller brush is provided in the main air duct 3111. At least a part of the sub-air duct 3112 is left empty, so that the dust in the cleaning cover 31 enters the dust storage chamber 11 from the sub-air duct 3112, preventing a large amount of dust from being caught by the roller brush, and ensuring the cleaning ability of the cleaning robot.

[0105] In addition, a main air duct 3111 and a sub-air duct 3112 are provided inside the cleaning cover 31. The roller brush is provided inside the main air duct 3111, and at least a part of the sub-air duct 3112 is left empty, so that dust can move inside the sub-air duct 3112, thereby making it difficult for the dust to be caught by the roller brush.

[0106] In an embodiment of the present disclosure, the main air duct 3111 and the sub-air duct 3112 are arranged along the width direction of the cleaning cover 31, so that the length of the roller brush inside the main air duct 3111 can be ensured, and the cleaning area of the roller brush can be ensured.

[0107] As an alternative embodiment of the present disclosure, the main air duct 3111 and the sub-air duct 3112 may be arranged along the length direction of the cleaning cover 31.

[0108] In an embodiment of the present disclosure, the volume of the main air duct 3111 is larger than the volume of the sub-air duct 3112, so that the roller brush can be effectively accommodated, and it is not necessary for the volume of the cleaning cover 31 to be too large. On the premise of ensuring the cleaning ability of the cleaning robot, it is possible to avoid the cleaning module 30 occupying too much space of the cleaning robot.

[0109] In the cleaning robot provided by the embodiment of the present disclosure, the cleaning module 30 has an air duct opening 312. The cleaning module 30 communicates with the dust storage chamber 11 through the air duct opening 312. The air duct opening 312 is provided away from the central position in the length direction of the cleaning module 30, so that the cleaning module 30 can timely discharge dust into the dust storage chamber 11, avoid dust clogging, and improve the cleaning ability of the cleaning robot.

[0110] In an embodiment of the present disclosure, as shown in FIG. 21, an air duct opening 312 is provided on the cleaning cover 31, and the secondary air duct 3112 and the dust storage chamber 11 communicate with each other through the air duct opening 312. Here, the air duct opening 312 is provided offset from the central position in the length direction of the cleaning cover 31, thereby avoiding dust clogging and ensuring the cleaning ability of the cleaning robot.

[0111] The air duct opening 312 may be connected to the dust inlet 1112 of the dust box 10.

[0112] In an embodiment of the present disclosure, along the length direction of the cleaning cover 31, the minimum vertical distance between the air duct opening 312 and the central position of the cleaning cover 31 is greater than the minimum vertical distance between the air duct opening 312 and the inner wall of the cleaning cover 31. Therefore, the air duct opening 312 is provided as much as possible offset from the central position of the cleaning cover 31, thereby ensuring that dust can be discharged reliably.

[0113] As an alternative embodiment of the present disclosure, the air duct opening 312 may be provided at the central position in the length direction of the cleaning cover 31.

[0114] In an embodiment of the present disclosure, as shown in FIGS. 22 and 23, the secondary air duct 3112 includes a first air duct segment 3113 and a second air duct segment 3114. The first air duct segment 3113 and the second air duct segment 3114 are provided along the length direction of the cleaning cover 31. One end of the second air duct segment 3114 away from the first air duct segment 3113 communicates with the air duct opening 312, thereby providing the air duct opening 312 offset from the central position in the length direction of the cleaning cover 31.

[0115] Note that the first air duct segment 3113 and the second air duct segment 3114 are provided along the length direction of the cleaning cover 31. Importantly, the auxiliary air duct 3112 extends along the length direction of the cleaning cover 31. Along the length direction of the cleaning cover 31, the auxiliary air duct 3112 can be divided into the first air duct segment 3113 and the second air duct segment 3114. One end of the second air duct segment 3114 away from the first air duct segment 3113 communicates with the air duct opening 312. That is, the air duct opening 312 is substantially located at the end side of the auxiliary air duct 3112. Thereby, the air duct opening 312 is provided away from the central position in the length direction of the cleaning cover 31.

[0116] In the embodiment of the present disclosure, the extending direction of the first air duct segment 3113 and the extending direction of the second air duct segment 3114 are not parallel. The gas flow direction in the first air duct segment 3113 may be the extending direction of the first air duct segment 3113. The extending direction of the first air duct segment 3113 may be the length direction of the cleaning cover 31. The gas flow direction in the second air duct segment 3114 may be the extending direction of the second air duct segment 3114. The extending direction of the second air duct segment 3114 may be offset from the length direction of the cleaning cover 31. Thereby, the air flow direction in the auxiliary air duct 3112 forms a curved passage. On the premise that dust can be surely discharged into the dust box 10, the layout of the air duct can be made more reasonable.

[0117] In the embodiment of the present disclosure, the extending direction of the first air duct segment 3113 and the extending direction of the second air duct segment 3114 may be substantially perpendicular. That is, the second air duct segment 3114 forms an air duct segment protruding from the first air duct segment 3113.

[0118] As an alternative embodiment of the present disclosure, the extending direction of the first air duct segment 3113 and the extending direction of the second air duct segment 3114 overlap. At this time, the air duct opening 312 is provided on the bottom wall of the second air duct segment 3114.

[0119] In an embodiment of the present disclosure, since there is an arc-shaped transition portion between the first air duct segment 3113 and the second air duct segment 3114, it is ensured that dust smoothly enters from the first air duct segment 3113 into the second air duct segment 3114. Thereby, the dust discharging capacity of the auxiliary air duct 3112 can be improved.

[0120] As an alternative embodiment of the present disclosure, there may be a right-angled transition portion between the first air duct segment 3113 and the second air duct segment 3114.

[0121] In an embodiment of the present disclosure, there are at least two main air ducts 3111, and the auxiliary air duct 3112 is arranged between adjacent main air ducts 3111, so that the dust in the main air duct 3111 surely enters the auxiliary air duct 3112, and the dust in the auxiliary air duct 3112 enters the dust box 10 through the air duct opening 312.

[0122] In an embodiment of the present disclosure, as shown in FIG. 23, there are two main air ducts 3111, and one auxiliary air duct 3112 is arranged between the two main air ducts 3111, and the volume of the main air duct 3111 is larger than the volume of the auxiliary air duct 3112.

[0123] In an embodiment of the present disclosure, along the length direction of the cleaning cover 31, a part of the main air duct 3111 is left empty, so that the dust on the roller brush enters the auxiliary air duct 3112 from the empty position of the main air duct 3111 and is discharged, and the cleaning ability of the cleaning robot can be improved.

[0124] As an alternative embodiment of the present disclosure, along the length direction of the cleaning cover 31, the length of the main air duct 3111 coincides with the length of the roller brush.

[0125] In addition, the horizontal axis of the cleaning robot is substantially parallel to the roller brush. At this time, the length direction of the cleaning cover 31 can be regarded as the horizontal axis parallel to the cleaning robot. The width direction of the cleaning cover 31 can be regarded as the vertical axis parallel to the cleaning robot.

[0126] As an alternative embodiment of the present disclosure, the horizontal axis of the cleaning robot forms a predetermined angle with the roller brush. When the cleaning robot passes horizontally through a floor environment such as a tile joint, the probability that the roller brush gets caught on the joint is reduced, the cleaning efficiency of the cleaning robot is improved, and the performance of the cleaning robot can be improved. The predetermined angle between the horizontal axis and the roller brush may be an acute angle, and the range of the predetermined angle may be from 5 degrees to 70 degrees.

[0127] The cleaning module 30 may include a roller brush. The roller brush has a boom structure, and the boom structure is a conical structure. The first end of the conical structure is connected to the cleaning cover 31, the second end of the conical structure is the boom end, and the diameter of the first end is larger than the diameter of the second end.

[0128] As shown in FIG. 20A, the cleaning module 30 includes a first cleaning set and a second cleaning set. The first cleaning set includes a first roller brush 32 and a second roller brush 33. The second cleaning set includes a third roller brush 34 and a fourth roller brush 35. The first roller brush 32 and the second roller brush 33 may be the same roller brush, or the first roller brush 32 and the second roller brush 33 may be different roller brushes. The third roller brush 34 and the fourth roller brush 35 may be the same roller brush, or the third roller brush 34 and the fourth roller brush 35 may be different roller brushes. The first roller brush has a conical structure, and / or the second roller brush has a conical structure.

[0129] A first gap is formed between the first roller brush 32 and the second roller brush 33 of the first cleaning group, and a second gap is formed between the third roller brush 34 and the fourth roller brush 35 of the second cleaning group. When the first roller brush 32 and the second roller brush 33 are arranged along the length direction of the cleaning cover 31, the third roller brush 34 and the fourth roller brush 35 are arranged along the length direction of the cleaning cover 31, and the first cleaning group and the second cleaning group are arranged along the width direction of the cleaning cover 31, the first gap and the second gap can be arranged along the width direction of the cleaning cover 31.

[0130] As an alternative embodiment of the present disclosure, when the first roller brush 32 and the second roller brush 33 are arranged along the width direction of the cleaning cover 31, the third roller brush 34 and the fourth roller brush 35 are arranged along the width direction of the cleaning cover 31, and the first cleaning group and the second cleaning group are arranged along the length direction of the cleaning cover 31, the first gap and the second gap can be arranged along the length direction of the cleaning cover 31.

[0131] In an embodiment of the present disclosure, the roller brush may include a first roller brush 32, a second roller brush 33, a third roller brush 34, and a fourth roller brush 35.

[0132] The second roller brush 33 is provided at a distance from the first roller brush 32. Here, since the second roller brush 33 and the first roller brush 32 are provided along the length direction of the cleaning cover 31, a first gap is formed between the second roller brush 33 and the first roller brush 32, and dust can easily enter the secondary air duct 3112 through the first gap, ensuring the cleaning ability of the first roller brush 32 and the second roller brush 33 and being able to timely discharge the dust on the first roller brush 32 and the second roller brush 33.

[0133] The third roller brush 34 and the first roller brush 32 are provided along the width direction of the cleaning cover 31. The fourth roller brush 35 and the third roller brush 34 are provided at intervals along the length direction of the cleaning cover 31, and together with the second roller brush 33, they are provided along the width direction of the cleaning cover 31. By forming a two-row and two-column roller brush within the cleaning cover 31, the cleaning ability of the cleaning module 30 can be improved.

[0134] The fourth roller brush 35 and the third roller brush 34 are provided at intervals along the length direction of the cleaning cover 31, whereby a second gap is formed between the fourth roller brush 35 and the third roller brush 34. Dust can easily enter the secondary air duct 3112 through the second gap, ensuring the cleaning ability of the fourth roller brush 35 and the third roller brush 34, and enabling timely discharge of the dust on the fourth roller brush 35 and the third roller brush 34.

[0135] As an alternative embodiment of the present disclosure, the first roller brush 32 and the second roller brush 33 may have a conical structure, and the third roller brush 34 and the fourth roller brush 35 may have a cylindrical structure. The conical structure is used to entangle hairs, and the cylindrical structure has a good cleaning effect and can reduce costs. The first roller brush 32 and the second roller brush 33 may have a cylindrical structure, and the third roller brush 34 and the fourth roller brush 35 may have a conical structure.

[0136] As an alternative embodiment of the present disclosure, the first roller brush 32, the second roller brush 33, the third roller brush 34, and the fourth roller brush may all have a conical structure or a cylindrical structure.

[0137] In an embodiment of the present disclosure, along the width direction of the cleaning cover 31, the third roller brush 34 and the first roller brush 32 may be in contact with each other, or the third roller brush 34 and the first roller brush 32 may be in at least point contact, thereby improving the cleaning ability of the third roller brush 34 and the first roller brush 32.

[0138] In an embodiment of the present disclosure, along the width direction of the cleaning cover 31, the fourth roller brush 35 and the second roller brush 33 may be in contact with each other, and the fourth roller brush 35 and the second roller brush 33 may be at least in point contact, whereby the cleaning capabilities of the fourth roller brush 35 and the second roller brush 33 can be improved.

[0139] The roller brush includes vanes for achieving cleaning in the circumferential direction. By installing the first roller brush 32, the second roller brush 33, the third roller brush 34, and the fourth roller brush 35, during the cleaning process of the cleaning robot, the rear roller brush increases the contact line speed and contact time between the vanes and the carpet, thereby improving the cleaning ability. Compared with a single brush in the related art, the present disclosure includes a rear roller brush, which has a rotation direction opposite to that of the front roller brush and is driven to move dust such as hair forward, thereby improving the cleaning effect on carpets and the like.

[0140] In an embodiment of the present disclosure, since the axis of the second roller brush 33 is not parallel to the axis of the first roller brush 32, an angle is formed between the end of the second roller brush 33 and the end of the first roller brush 32 to facilitate the discharge of dust.

[0141] Since the axis of the fourth roller brush 35 is not parallel to the axis of the third roller brush 34, an angle is formed between the end of the fourth roller brush 35 and the end of the third roller brush 34 to facilitate the discharge of dust.

[0142] By setting the angle formed between the end of the second roller brush 33 and the end of the first roller brush 32 to be opposite to the angle formed between the end of the fourth roller brush 35 and the end of the third roller brush 34, on the premise of facilitating the discharge of dust, the problem of cleaning leakage of the roller brush can be prevented.

[0143] In an embodiment of the present disclosure, as shown in FIG. 20A, a first gap 38 is formed between the second roller brush 33 and the first roller brush 32, and a second gap 39 is formed between the fourth roller brush 35 and the third roller brush 34. By alternately setting the first gap 38 and the second gap 39, the first roller brush 32, the second roller brush 33, the third roller brush 34, and the fourth roller brush 35 form a closed cleaning space during the cleaning process, avoiding the problem of cleaning leakage and ensuring that dust is discharged from the first gap 38 and the second gap 39.

[0144] In an embodiment of the present disclosure, as shown in FIG. 20A, the length of the first roller brush 32 is smaller than the length of the second roller brush 33, and the length of the third roller brush 34 is larger than the length of the fourth roller brush 35. Therefore, a first gap is formed between the second roller brush 33 and the first roller brush 32, a second gap is formed between the fourth roller brush 35 and the third roller brush 34, and the first gap and the second gap are alternately set.

[0145] As an alternative embodiment of the present disclosure, a first gap is formed between the second roller brush 33 and the first roller brush 32, a second gap is formed between the fourth roller brush 35 and the third roller brush 34, and the first gap and the second gap are provided opposite to each other. However, the angle formed between the end of the second roller brush 33 and the end of the first roller brush 32 is set opposite to the angle formed between the end of the fourth roller brush 35 and the end of the third roller brush 34, thereby avoiding the problem of cleaning leakage of the roller brush on the premise of facilitating the discharge of dust.

[0146] As an alternative embodiment of the present disclosure, the length of the first roller brush 32 is approximately the same as the length of the third roller brush 34, and the length of the second roller brush 33 is approximately the same as the length of the fourth roller brush 35. However, the angle formed between the end of the second roller brush 33 and the end of the first roller brush 32 is set opposite to the angle formed between the end of the fourth roller brush 35 and the end of the third roller brush 34.

[0147] In an embodiment of the present disclosure, at least one of the first roller brush 32, the second roller brush 33, the third roller brush 34, and the fourth roller brush 35 has a conical structure. On the premise that the roller brush can be reliably cleaned, dust can be easily removed from the roller brush.

[0148] In an embodiment of the present disclosure, the first end of the conical structure is connected to the cleaning cover 31, and the second end of the conical structure is the boom end. As a result, a gap is formed between adjacent conical structures, and dust can be easily removed from the roller brush. The dust enters the secondary air duct 3112 through the gap and is finally discharged into the dust box 10.

[0149] In an embodiment of the present disclosure, the first roller brush 32, the second roller brush 33, the third roller brush 34, and the fourth roller brush 35 rotate synchronously, so that the roller brush can quickly clean the surface to be cleaned and improve the cleaning ability of the cleaning module 30.

[0150] In an embodiment of the present disclosure, the first roller brush 32 and the second roller brush 33 are provided in one main air duct 3111, the third roller brush 34 and the fourth roller brush 35 are provided in another main air duct 3111, and a secondary air duct 3112 is arranged between the two main air ducts 3111.

[0151] The rotation directions of the first roller brush 32 and the second roller brush 33 are opposite to the rotation directions of the third roller brush 34 and the fourth roller brush 35, so that dust can be quickly collected into the cleaning module 30, and the dust can enter the dust box 10 through the secondary air duct 3112.

[0152] As an alternative embodiment of the present disclosure, the rotation directions of the first roller brush 32 and the second roller brush 33 are the same as the rotation directions of the third roller brush 34 and the fourth roller brush 35.

[0153] Note that the rotation directions may be opposite, i.e., one is clockwise and the other is counterclockwise.

[0154] As shown in FIG. 20F, in the air duct device provided by the embodiment of the present disclosure, the air duct device includes a cleaning module 30, a dust storage chamber 11, and a dust suction air duct 73. Here, the cleaning module 30 includes a cleaning cover 31, and the cleaning module 30 further includes a roller brush, and the roller brush is provided in the cleaning cover 31. Here, the dust storage chamber 11 may be a dust storage chamber 11 formed in the dust box 10, or may be a dust storage chamber 11 formed in the device main body 20. The dust suction air duct 73 communicates the cleaning cover 31 and the dust storage chamber 11, and the dust suction air duct 73 includes a communicating air inlet end and an air outlet end 733. The air inlet end is connected to the cleaning cover 31, and the air outlet end 733 is connected to the dust storage chamber 11. That is, in the present disclosure, the air flow passes through the cleaning cover 31 of the cleaning module 30, the dust suction air duct 73, and the dust storage chamber 11 and flows to the external environment, constituting the air duct device. The third air duct 731 is provided inclined with respect to the horizontal plane. Due to the inclined dust suction air duct 73, the air flow flowing through the cleaning cover 31 is shunted in the dust suction air duct 73 provided inclined with respect to the horizontal plane, thereby reducing the air flow noise, and thus reducing the noise generated during the working process of the cleaning robot, and improving the comfort of the user.

[0155] Here, when the dust suction air duct 73 is provided inclined with respect to the horizontal plane, the dust suction air duct 73 may be provided inclined upward with respect to the horizontal plane from the side closer to the cleaning cover 31 toward the side away from the cleaning cover 31, or the dust suction air duct 73 may be provided inclined downward with respect to the horizontal plane from the side closer to the cleaning cover 31 toward the side away from the cleaning cover 31. Specifically, an air duct opening 312 is provided on the cleaning cover 31, and the air duct opening 312 communicates with the dust suction air duct 73. After the gas is discharged from the air duct opening 312 of the cleaning cover 31, a part of the air flow acts on the inner wall of the dust suction air duct 73 facing the air duct opening 312. Since the dust suction air duct 73 is provided inclined with respect to the horizontal plane, that is, the inner wall of the dust suction air duct 73 facing the air duct opening 312 is provided inclined with respect to the horizontal plane, the air flow is diverted after acting on the inner wall of the dust suction air duct 73 facing the air duct opening 312, so that the purpose of reducing the air flow noise can be achieved.

[0156] As shown in FIG. 20F, the air duct device provided by the present disclosure includes a third air duct 731 and a fourth air duct 732 that are in communication with each other. Here, an air duct opening 312 is formed in the cleaning cover 31. The third air duct 731 is connected to the cleaning cover 31 through the air duct opening 312, and the fourth air duct 732 is connected to the dust storage chamber 11. Here, the third air duct 731 is provided inclined with respect to the air duct opening 312 or vertically. After the gas is discharged from the air duct opening 312 of the cleaning cover 31, it is diverted by the third air duct 731 provided inclined with respect to the horizontal plane, and then flows into the dust storage chamber 11 through the fourth air duct 732, thereby achieving the purposes of gas flow and noise reduction.

[0157] Here, since the dust suction air duct 73 includes a third air duct 731 and a fourth air duct 732, the third air duct 731 is provided inclined or vertically with respect to the air duct opening 312, and then, according to the connection position between the third air duct 731 and the dust storage chamber 11, by reasonably setting the structure of the fourth air duct 732, the third air duct 731 is connected to the dust storage chamber 11, and the communication between the cleaning cover 31 and the dust storage chamber 11 is realized. With the setting of the fourth air duct 732, when it is ensured that the third air duct 731 and the cleaning cover 31 have a sufficient inclination angle to reduce the airflow noise, the transient communication between the third air duct 731 and the dust storage chamber 11 contributes to the reduction of the overall height of the dust suction air duct 73, meeting the design requirements of miniaturization and compact structure of the cleaning robot.

[0158] Furthermore, the angle between the third air duct 731 and the air duct opening 312 may be less than 90°, equal to 90°, or greater than 90° to meet the requirement that the third air duct 731 is provided along different directions with respect to the air duct opening 312. Specifically, by setting the angle between the third air duct 731 and the air duct opening 312 to be greater than 90°, the airflow flowing through the cleaning cover 31 can flow through the third air duct 731 quickly and smoothly, ensuring a good air flow effect. At the same time, since the airflow is diverted within the third air duct 731, the airflow noise can be reduced, further ensuring a good cleaning efficiency, reducing the noise generated during the working process of the cleaning robot, and improving the comfort of the user.

[0159] Here, the third air duct 731 and the fourth air duct 732 may be of an integral structure or a separate structure. The integral third air duct 731 and fourth air duct 732 enable mass production and improve production efficiency, while the separate third air duct 731 and fourth air duct 732 can reduce maintenance and replacement costs. Specifically, the separate third air duct 731 and fourth air duct 732 may be inserted and connected, or connected by other fasteners such as bolts. In order to ensure the connection sealing performance between the third air duct 731 and the fourth air duct 732, a sealing member may be provided at their connection position.

[0160] Here, the third air duct 731 and the cleaning cover 31 may be of an integral structure or a separate structure. When the third air duct 731 and the cleaning cover 31 are of an integral structure, mass production is possible, contributing to the improvement of production efficiency. When the third air duct 731 and the cleaning cover 31 are of a separate structure, the maintenance and replacement costs can be reduced. Specifically, the separate third air duct 731 and cleaning cover 31 are connected by other fasteners such as bolts. In order to ensure the connection sealing performance between the third air duct 731 and the cleaning cover 31, a sealing member may be provided at their connection position.

[0161] Specifically, the third air duct 731, the fourth air duct 732, and the cleaning cover 31 may be of an integral structure, or they may be of a separate structure. Or, the third air duct 731 and the fourth air duct 732 may be of an integral structure, and the two as a whole may be of a separate structure from the cleaning cover 31. Or, the third air duct 731 and the cleaning cover 31 may be of an integral structure, and the two as a whole may be of a separate structure from the fourth air duct 732.

[0162] The third air duct 731 provided by the present disclosure is provided upward, inclined with respect to the horizontal plane, from a direction close to the cleaning cover 31 toward a direction away from the cleaning cover 31, so that the design requirement of a small bottom space of the cleaning robot can be satisfied. The third air duct 731 and the cleaning cover 31 have a sufficient inclination angle to reduce the airflow noise and have a good air flow effect, thereby ensuring good cleaning efficiency of the cleaning robot.

[0163] Furthermore, the third air duct 731 has an arc-shaped structure. Due to the arc-shaped third air duct 731, gas smoothly enters from the cleaning cover 31 into the fourth air duct 732, passes through the fourth air duct 732 and enters the dust storage chamber 11, thereby improving the ventilation capacity and ventilation efficiency of the dust suction air duct 73, reducing problems such as dust clogging, and ensuring the cleaning efficiency of the cleaning robot. Specifically, the arc-shaped air duct is provided upward, inclined in the direction from the cleaning cover 31 toward the fourth air duct 732.

[0164] Here, the side wall surface of the third air duct 731 includes a curved surface, so that the air flow smoothly flows inside the third air duct 731, thereby reducing problems such as dust clogging and contributing to the improvement of the air flow efficiency and smoothness of the air flow.

[0165] In the embodiment provided by the present disclosure, the fourth air duct 732 is substantially a horizontal air duct. Due to the substantially horizontal air duct, the vertical height of the air duct device is not increased, and the design requirements of a small cleaning robot volume and a compact structure can be satisfied. At the same time, good air flow efficiency can be ensured, and the cleaning efficiency of the cleaning robot can be ensured.

[0166] In addition, in some realizable embodiments, the fourth air duct 732 may be provided downward, inclined in the direction from the third air duct 731 toward the dust storage chamber 11, or, when not considering the overall height of the air duct device, the fourth air duct 732 may be provided upward, inclined in the direction from the third air duct 731 toward the dust storage chamber 11.

[0167] Here, since the side wall surface of the fourth air duct 732 includes a curved surface, the airflow smoothly flows through the fourth air duct 732, thereby reducing problems such as dust clogging and contributing to the improvement of the air flow efficiency and smoothness of the air flow.

[0168] Optionally, the fourth air duct 732 is a flexible air duct and may be made of a material such as flexible rubber or silicone. The cleaning cover (including a roller brush inside) has an effect of floating up and down with respect to the main body. When there are obstacles on the surface to be cleaned, the up and down floating of the floating main brush structure reduces the interaction between the roller brush and the obstacles, thereby assisting in easily realizing the obstacle crossing of the automatic cleaning device. The dust suction air duct is arranged between the dust storage chamber and the cleaning cover structure, and the dust suction air duct needs to have flexibility because a rigid air duct cannot absorb the floating change of the roller brush. When the fourth air duct is made of a flexible material such as flexible rubber, during the obstacle crossing process, the dust suction air duct can be pressed and deformed through the floating bracket to smoothly realize the upward "floating". The third air duct (inclined part) in the dust suction air duct is made of a rigid material (to obtain a smoother air flow), and the fourth air duct is made of a flexible material.

[0169] In an embodiment of the present disclosure, as shown in FIG. 21, the cleaning module further includes a drive structure 36. The drive structure 36 includes a power unit 361 and a transmission assembly. The power unit 361 drives the first roller brush 32, the second roller brush 33, the third roller brush 34, and the fourth roller brush 35 to rotate synchronously through the transmission assembly, thereby realizing reliable cleaning of the surface to be cleaned. The power unit 361 drives the plurality of roller brushes to rotate synchronously by the transmission assembly, thereby ensuring the synchronous cleaning of the plurality of roller brushes while reducing the power unit 361 and improving the cleaning ability of the cleaning robot.

[0170] In an embodiment of the present disclosure, as shown in FIGS. 24 and 25, the transmission assembly includes a first wheel body 362, a second wheel body 363, a third wheel body 364, a fourth wheel body 365, a fifth wheel body 366, a sixth wheel body 367, a seventh wheel body 368, an eighth wheel body 369, a transmission rod 3610, a ninth wheel body 3611, a tenth wheel body 3612, an eleventh wheel body 3613, a twelfth wheel body 3614, and a thirteenth wheel body 3615.

[0171] The power unit 361 may be connected to the first wheel body 362, and the power unit 361 drives the first wheel body 362 to rotate. The first wheel body 362 meshes with the second wheel body 363 and drives the third wheel body 364 connected to the second wheel body 363 to rotate. The third wheel body 364 and the fourth wheel body 365 mesh with each other. The fourth wheel body 365 meshes with the fifth wheel body 366, the sixth wheel body 367, and the eighth wheel body 369 at the same time. As a result, the sixth wheel body 367 drives the third roller brush 34 to rotate along the first direction. The eighth wheel body 369 drives the transmission rod 3610 to rotate. Correspondingly, the fifth wheel body 366 can drive the seventh wheel body 368, so that the seventh wheel body 368 drives the first roller brush 32 to rotate along the second direction. The rotation direction of the first roller brush 32 is opposite to the rotation direction of the third roller brush 34.

[0172] The transmission rod 3610 drives the ninth wheel body 3611 connected thereto to rotate. The ninth wheel body 3611 and the tenth wheel body 3612 mesh with each other. The tenth wheel body 3612 meshes with the eleventh wheel body 3613 and the twelfth wheel body 3614. The eleventh wheel body 3613 drives the fourth roller brush 35 to rotate along the first direction. The twelfth wheel body 3614 and the thirteenth wheel body 3615 mesh with each other. The thirteenth wheel body 3615 drives the second roller brush 33 to rotate along the second direction. The rotation direction of the second roller brush 33 is opposite to the rotation direction of the fourth roller brush 35.

[0173] It should be noted that each of the above wheel bodies may be a gear, and the power unit 361 may be a motor.

[0174] As a selectable embodiment of the present disclosure, the cleaning module 30 includes at least two motors, and each motor can be driven to rotate one or two roller brushes. For example, there may be four motors, and the four motors can be driven to easily rotate the first roller brush 32, the second roller brush 33, the third roller brush 34, and the fourth roller brush 35. The rotation speeds of the first roller brush 32, the second roller brush 33, the third roller brush 34, and the fourth roller brush 35 may be the same or different.

[0175] In an embodiment of the present disclosure, the roller brush is detachably provided on the cleaning cover 31. By detachably providing at least one of the first roller brush 32, the second roller brush 33, the third roller brush 34, and the fourth roller brush 35 on the cleaning cover 31, the roller brush can be easily replaced and maintained.

[0176] In an embodiment of the present disclosure, the second roller brush 33 is provided so as to be movable in its axial direction, and thus can be removed from the cleaning cover 31. The second roller brush 33 is connected to the cleaning cover 31 by a specific member. Under normal use conditions, the second roller brush 33 is securely fixed to the cleaning cover 31. When it is necessary to maintain or replace the second roller brush 33, by adjusting the position of the second roller brush 33, removal from the cleaning cover 31 can be achieved.

[0177] As shown in FIGS. 20A to 20C, the second roller brush 33 will be described as an example.

[0178] As shown in FIGS. 20B and 20C, the cleaning module includes a main body support member 331 provided on the cleaning cover 31, and an adapter member 332 to which the second roller brush 33 is connected. The adapter member 332 is movably provided with respect to the main body support member 331, and has a first position connected to the main body support member 331 and a second position separated from the main body support member 331. The adapter member 332 is further provided with an elastic member 334 connected to the adapter member 332 and arranged along the axial direction of the second roller brush 33. Here, the second roller brush 33 moves along its axial direction together with the adapter member 332. When the elastic member 334 is compressed, the adapter member 332 moves from the first position to the second position. When the adapter member 332 is rotated, the second roller brush 33 can be separated from the main body support member 331 along its axial direction together with the adapter member 332.

[0179] An engagement groove 3311 is provided on the main body support member 331, and a snap fit 333 is provided on the adapter member 332. When the adapter member 332 moves from the first position to the second position, the snap fit 333 can be disengaged from the engagement groove 3311. Here, when the adapter member 332 is in the second position, when the adapter member 332 is rotated, the snap fit 333 is disengaged from the engagement groove 3311.

[0180] The second roller brush 33 is connected to the adapter member 332, a snap fit 333 is provided on the adapter member 332, an elastic member 334 is connected to one end of the adapter member 332, the main body support member 331 is connected to the cleaning cover 31 via a power adapter 335, the adapter member 332 is connected to the main body support member 331 via the snap fit 333, the elastic member 334 is sandwiched between the adapter member 332 and the power adapter 335, and by driving the adapter member 332 to move along the length direction of the second roller brush 33, that is, to move the adapter member 332 along the axial direction of the second roller brush 33, the locking between the snap fit 333 and the main body support member 331 is released, and the adapter member 332 and the second roller brush 33 can be rotated. At this time, the snap fit 333 disengages from the engaging groove 3311, whereby the adapter member 332 can be removed from the main body support member 331, and the second roller brush 33 can be removed from the cleaning cover 31.

[0181] A part of the adapter member 332 is inserted and provided in the main body support member 331, and the snap fit 333 is provided in the engaging groove 3311, so that locking with the main body support member 331 is realized. At this time, the second roller brush 33 is firmly fixed to the cleaning cover 31. By compressing the elastic member 334, the locking between the snap fit 333 and the main body support member 331 is released, so that by rotating the adapter member 332, the snap fit 333 disengages from the engaging groove 3311. At this time, the main body support member 331 can press the snap fit 333, and no locking relationship is formed between the snap fit 333 and the main body support member 331, and the adapter member 332 can be pulled out from the main body support member 331, and the second roller brush 33 can be removed from the cleaning cover 31.

[0182] Since the body support member 331 has a conical tube structure, by compressing the elastic member 334, the locking between the snap fit 333 and the body support member 331 is released. When the adapter member 332 is rotated, the snap fit 333 disengages from the engagement groove 3311. Since the snap fit 333 has already entered from a position with a smaller diameter to a position with a larger diameter, it can disengage from the engagement groove 3311.

[0183] A plurality of snap fits 333 are provided on the adapter member 332, and the snap fits 333 may be elastically deformed. The elastic member 334 may have a structure such as a spring or a rubber ring. The 13th wheel body 3615 may be connected to the power adapter 335 and drive the second roller brush 33 to rotate.

[0184] Note that the axial direction of the second roller brush 33 may include the direction from left to right and the direction from right to left.

[0185] As an alternative embodiment of the present disclosure, the roller brush of the cleaning module may include only the first roller brush 32 and the second roller brush 33, that is, the cleaning robot may be a two-brush cleaning robot. The first roller brush 32 and the second roller brush 33 may be provided on the cleaning cover 31 at intervals along the length direction of the cleaning cover 31.

[0186] As an alternative embodiment of the present disclosure, the roller brush of the cleaning module may include only the first roller brush 32, the second roller brush 33 and the third roller brush 34, that is, the cleaning robot may be a three-brush cleaning robot. The first roller brush 32 and the second roller brush 33 may be provided on the cleaning cover 31 at intervals along the length direction of the cleaning cover 31, and the third roller brush 34 and the first roller brush 32 may be provided on the cleaning cover 31 along the width direction of the cleaning cover 31. Both ends of the third roller brush 34 may be substantially flush with the end of the first roller brush 32 and the end of the second roller brush 33. Or the length of the third roller brush 34 may be smaller than the sum of the lengths of the first roller brush 32 and the second roller brush 33.

[0187] As a selectable embodiment of the present disclosure, as shown in FIG. 26, the cleaning module 30 includes a cleaning cover 31, a first roller brush structure 301, and a second roller brush structure 302. The first roller brush structure 301 and the second roller brush structure 302 are provided within the cleaning cover 31. Both the first roller brush structure 301 and the second roller brush structure 302 extend along the length direction of the cleaning cover 31. By arranging the first roller brush structure 301 and the second roller brush structure 302 along the width direction of the cleaning cover 31, the first roller brush structure 301 and the second roller brush structure 302 can surely clean the surface to be cleaned.

[0188] The lengths of the first roller brush structure 301 and the second roller brush structure 302 may be substantially the same.

[0189] The rotation directions of the first roller brush structure 301 and the second roller brush structure 302 may be opposite, whereby dust can be quickly collected into the cleaning module 30. The first roller brush structure 301 and the second roller brush structure 302 can be driven to rotate by two independent drive mechanisms. Alternatively, the first roller brush structure 301 and the second roller brush structure 302 can be driven to rotate by one drive mechanism. The specific structure of the drive mechanism is not limited. For example, by being driven by a motor and a drive wheel assembly, synchronous driving of the first roller brush structure 301 and the second roller brush structure 302 can be realized by one motor. Alternatively, the rotation of the first roller brush structure 301 and the second roller brush structure 302 can be conveniently driven by two motors.

[0190] As shown in FIGS. 27A to 29, for the cleaning robot according to an embodiment of the present disclosure, the fan assembly 40 includes a fan 41, an air duct 42, and a filtration unit 43. One end of the air duct 42 communicates with the fan 41, the other end of the air duct 42 communicates with the dust storage chamber 11, and the filtration unit 43 is disposed between the dust storage chamber 11 and the air duct 42, so that the filtration unit 43 can reliably filter the gas discharged into the room. Since the air duct 42 communicates the fan 41 and the filtration unit 43, not only can the gas be reliably discharged into the room, but also the air duct 42 is arranged according to the internal space of the cleaning robot, maximizing the utilization rate of the internal space of the cleaning robot and improving the performance of the cleaning robot.

[0191] In an embodiment of the present disclosure, the dust box 10 includes a first cavity 111 and a second cavity 112 that communicate with each other. The first cavity 111 communicates with the cleaning module 30, the cyclone separator 13 is provided in the second cavity 112, and the fan assembly 40 communicates with the second cavity 112. Therefore, the fan assembly 40 can reliably collect the dust on the surface to be cleaned into the dust box 10 through the cleaning module 30.

[0192] In an embodiment of the present disclosure, the dust box 10 is provided adjacent to the fan assembly 40, and the dust box 10 and the fan assembly 40 are provided along the circumferential direction of the main body 20, so that not only the structural distribution is reasonable, but also the communication path between the dust box 10 and the fan assembly 40 can be shortened.

[0193] It should be noted that the air duct 42 is used as an air flow path connecting the fan 41 and the filtration unit 43, and the structure can be adjusted according to the member distribution situation of the internal space of the cleaning robot, so it can adapt to the position and structural form of the internal space of the cleaning robot. For example, the fan 41 and the filtration unit 43 are provided in a staggered manner, and the fan 41 and the filtration unit 43 are arranged along the circumferential direction of the cleaning robot. At this time, the air duct 42 can effectively adapt to the layout of the fan 41 and the filtration unit 43, and the internal space of the cleaning robot can be utilized to the maximum extent.

[0194] The air outlet 1123 of the dust storage chamber 11 communicates with the filtering part 43, and the filtering part 43 is provided by being pressed between the air duct 42 and the dust box 10. Under the action of the fan 41, dust enters from the cleaning module 30 into the dust inlet 1112 of the dust storage chamber 11, enters the dust storage chamber 11 for particle separation, and finally the gas enters the filtering part 43 from the air outlet 1123 for filtering, then passes through the air duct 42, enters the fan 41, and is discharged from the cleaning robot, thereby realizing the collection of dust.

[0195] In an embodiment of the present disclosure, the wall surface of the air duct 42 is composed of at least one of a curved surface and a flat surface. By including a curved surface in the wall surface of the air duct 42, not only can the gas flow be promoted, but also the mounting positions of the fan 41 and the filtering part 43 can be utilized, so that the space adaptability of the air duct 42 can be improved.

[0196] In an embodiment of the present disclosure, as shown in FIGS. 27A to 28, the air duct 42 has a first air duct opening 421 and a second air duct opening 422. The first air duct opening 421 communicates with the fan 41, and the second air duct opening 422 communicates with the dust storage chamber 11. Here, since the second air duct opening 422 is a curved surface opening, it can adapt to the curved surface filtering part 43, thereby ensuring a reliable adaptation of the structure, increasing the filtering area of the filtering part 43, and improving the filtering ability of the filtering part 43.

[0197] In an embodiment of the present disclosure, since the area of the first air duct opening 421 is smaller than the area of the second air duct opening 422, the air flow in the dust storage chamber 11 can quickly enter the filtering part 43 for filtering, and the air flow entering speed into the fan 41 can be increased.

[0198] In an embodiment of the present disclosure, as shown in FIG. 29, the filtering part 43 includes a plurality of stacked filtering layers 431. The filtering layer 431 has a sheet-like structure. By stacking a plurality of sheet-like structures, not only can the filtering ability of the filtering part 43 be enhanced, but also it is not necessary to increase the size of the filtering part 43 in the thickness direction, and the internal space occupancy rate of the cleaning robot can be reduced.

[0199] As shown in FIG. 29, the filter layer 431 may be three layers, the thicknesses of the respective filter layers 431 may be the same, or the thicknesses of the respective filter layers 431 may be different. The areas of the respective filter layers 431 may be the same, or the areas of the respective filter layers 431 may be different.

[0200] In an embodiment of the present disclosure, the plurality of filter layers 431 are prepared from different materials, whereby the filtering ability of the filter unit 43 can be improved.

[0201] The filter layer 431 may be three layers, and the three filter layers 431 may be an electrostatic cotton, a filter cotton, and a sponge structure.

[0202] As an alternative embodiment of the present disclosure, the plurality of filter layers 431 are prepared from the same material.

[0203] In an embodiment of the present disclosure, as shown in FIG. 29, the filter unit 43 further includes a frame 432, the filter layer 431 is provided within the frame 432, and the frame 432 is sandwiched between the air duct 42 and the dust storage chamber 11, whereby the filter unit 43 can be securely fixed, avoiding the filter unit 43 from being crushed, and reliable filtering of the filter unit 43 can be achieved.

[0204] In an embodiment of the present disclosure, the filter layer 431 is three layers, and the area of the middle filter layer 431 is the largest, so that the fixing to the frame 432 can be ensured. The three filter layers 431 may be an electrostatic cotton, a filter cotton, and a sponge structure, increasing the dust holding amount of the filter unit 43. Since the frame 432 has a soft rubber structure, it is effectively pressed by the air duct 42 and the dust storage chamber 11, and reliable filtering can be achieved.

[0205] In an embodiment of the present disclosure, as shown in FIGS. 27A to 28, the fan assembly 40 further includes a sound-damping portion 44. The sound-damping portion 44 is provided on a side away from the air duct 42 of the fan 41 and communicates with the air outlet of the fan 41. Here, the sound-damping portion 44 includes a sound duct through-hole 441 and a sound-absorbing hole 442, and can also reduce the noise of the fan 41 and the gas flow noise.

[0206] After the gas exits the fan 41 and enters the sound-damping portion 44, a part of it is directly radiated from the sound duct through-hole 441 to the environment, and another part enters the sound-damping portion 44 through the sound-absorbing hole 442 on the wall surface of the sound duct through-hole 441 and is sound-absorbed, so that the purpose of noise reduction can be achieved. The sound-damping portion 44 may be sound-damping cotton or a porous material.

[0207] In an embodiment of the present disclosure, there are a plurality of sound duct through-holes 441. The plurality of sound duct through-holes 441 are provided at intervals along the height direction of the sound-damping portion 44, so that the gas can be reliably discharged into the room, and the purpose of the sound-damping portion 44 reducing noise can be reliably achieved.

[0208] In an embodiment of the present disclosure, the sound duct through-hole 441 has a first port and a second port. The aperture of the first port is smaller than the aperture of the second port. The first port of the sound duct through-hole 441 communicates with the air outlet of the fan 41, and the second port of the sound duct through-hole 441 communicates with the outside. Therefore, not only can effective exhaust be realized, but also the noise reduction effect can be reliably realized. Here, the aperture of the first port may be smaller than the aperture of the second port.

[0209] In an embodiment of the present disclosure, as shown in FIGS. 27B and 28, the fan assembly 40 further includes a filtering member 45 and a shield 46. The filtering member 45 is provided at an end of the sound-damping portion 44 away from the fan 41, so that the gas discharged from the sound-damping portion 44 can be filtered again. The shield 46 is connected to the main body 20, so that the fan assembly 40 can be effectively protected. The shield 46 may have a mesh structure to ensure reliable exhaust.

[0210] As shown in FIGS. 30 to 33, the cleaning base station includes a pile body 1, a dust barrel 4, a fan structure 7, a stop member 9, and a drive member 93.

[0211] The pile body 1 includes a dust inlet passage 2, the dust inlet passage 2 has a dust inlet 3, the dust inlet 3 communicates with an opening of the dust storage chamber 11, and is used to allow the dust in the dust storage chamber 11 to enter the dust inlet passage 2 through the dust inlet 3. The dust barrel 4 is provided on the pile body 1, and since the dust barrel 4 communicates with the dust inlet passage 2, the dust barrel 4 is used to collect the dust in the dust box 10 of the cleaning robot.

[0212] In an embodiment of the present disclosure, the stop member 9 is provided on the pile body 1, and since the stop member 9 can be in contact with or separated from the door body 12, when the stop member 9 contacts the door body 12, the door body 12 can be prevented from opening the dust storage chamber 11, and when the stop member 9 separates from the door body 12, the door body 12 can open the dust storage chamber 11.

[0213] The stop member 9 may simultaneously contact the first door body member 121 and the second door body member 122 of the door body 12, or the stop member 9 may contact one of the first door body member 121 and the second door body member 122 and separate from the other.

[0214] In an embodiment of the present disclosure, the fan structure 7 is provided on the pile body 1, and since the fan structure communicates with the dust barrel 4, the fan structure 7 can suck the dust in the dust box 10 into the dust barrel 4.

[0215] The fan structure 7 is provided on the pile body 1. The air inlet of the fan structure 7 communicates with the air flow outlet end of the dust barrel 4. The fan structure 7 generates negative pressure, enabling the dust in the dust box 10 to enter the dust inlet passage 2 through the dust inlet 3 and form an air flow circulation. Here, the dust in the dust box 10 includes the dust in the dust box. The fan structure 7 can suck and open the door body 12 of the dust box 10.

[0216] Specifically, when the cleaning robot completes cleaning, its battery power is insufficient, or it is triggered that its dust box is full of dust, the cleaning robot can return to the cleaning base station to charge or empty the dust in the dust box into the cleaning base station.

[0217] During the process of the cleaning robot returning to the cleaning base station, the cleaning robot constantly searches for the dust collection device by the signal receiving device. The cleaning base station is equipped with a signal transmitting device. For example, the signal transmitting device constantly transmits communication signals within a certain angle range for the cleaning robot to capture the signal. When the cleaning robot captures the communication signal, it determines the position of the cleaning base station and moves to the cleaning base station through the navigation function.

[0218] Furthermore, when the cleaning robot starts cleaning and departs from the cleaning base station, the position of the cleaning base station can be recorded on the map. Thus, during the process of returning to the cleaning base station, it preferentially goes to the position of the cleaning base station recorded on the map, determines the position of the cleaning base station by the signal transmitting device of the cleaning base station, and moves to the cleaning base station through the navigation function, thereby shortening the time to search for the cleaning base station and improving the efficiency of returning to the cleaning base station.

[0219] In an embodiment of the present disclosure, the stop member 9 is provided on the pile body 1. The stop member 9 is provided movably with respect to the pile body 1 and has a first position and a second position. Here, when the stop member 9 is in the first position, the stop member 9 prevents the door body 12 from opening the dust storage chamber 11. When the stop member 9 is in the second position, the door body 12 can open the opening so that the dust inlet 3 communicates with the opening. The door body 12 can open the opening, that is, the dust storage chamber 11 can be opened to an open state.

[0220] The stop member 9 can control the opening time of the door body 12. After the cleaning robot is combined with the cleaning base station, the stop member 9 can move from the first position in contact with the door body 12 to the second position separated from the door body 12, that is, the stop member 9 can move from the position where the door body 12 is blocked from opening the dust storage chamber 11 to the position where the door body 12 is not blocked from opening the dust storage chamber 11. At this time, by starting the fan structure 7, the door body 12 opens the dust storage chamber 11, whereby the dust in the dust box 10 is sucked into the dust barrel 4.

[0221] In an embodiment of the present disclosure, as shown in FIGS. 32 and 33, the stop member 9 includes a first stop member 91 and a second stop member 92. Since the first stop member 91 and the second stop member 92 respectively correspond to the first door body member 121 and the second door body member 122, the first door body member 121 and the second door body member 122 can independently open the first opening 1111 of the first cavity 111, the second opening 1121 of the second cavity 112, and the third opening 1122.

[0222] After the cleaning robot is combined with the cleaning base station, when the first stop member 91 moves from the first position to the second position and the second stop member 92 is held at the first position, by activating the fan structure 7, the first door body member 121 can open the first cavity 111 and discharge the dust in the first cavity 111 into the dust barrel 4. When the second stop member 92 moves from the first position to the second position and the first stop member 91 moves from the second position to the first position, the fan structure 7 causes the second door body member 122 to open the second cavity 112, thereby allowing the dust in the second cavity 112 to be discharged into the dust barrel 4.

[0223] By alternately opening the first cavity 111 and the second cavity 112, it is possible to easily ensure that the dust in the cleaning robot is sucked into the dust barrel 4.

[0224] In an embodiment of the present disclosure, as shown in FIGS. 32 and 33, the cleaning base station further includes a driving member 93. The driving member 93 is drivably connected to the first stop member 91 and the driving member 93 is drivably connected to the second stop member 92. When the first stop member 91 is in the first position, the second stop member 92 is in the second position, or when the first stop member 91 is in the second position, the second stop member 92 is in the first position. Thereby, the first cavity 111 and the second cavity 112 can be alternately opened, facilitating reliably sucking the dust in the cleaning robot into the dust barrel 4.

[0225] The drive member 93 may include a motor 931, a first gear 932, and a second gear 933. The motor 931 is connected to the first gear 932 and the second gear 933 via a drive shaft. The first gear 932 is engaged with the first rack 911 of the first stop member 91, and the second gear 933 is engaged with the second rack 921 of the second stop member 92. When the motor 931 operates, the first gear 932 and the second gear 933 rotate along the same direction, and the first rack 911 and the second rack 921 rotate along different directions. Thereby, when the first stop member 91 is in the first position, the second stop member 92 is in the second position, or when the first stop member 91 is in the second position, the second stop member 92 is in the first position.

[0226] The motor 931 is connected to the first gear 932 and the second gear 933 simultaneously. The first stop member 91 includes the first rack 911, and the second stop member 92 includes the second rack 921. The first gear 932 and the second gear 933 are respectively engaged with the first rack 911 and the second rack 921. When the first stop member 91 contacts the first door body member 121, the second stop member 92 separates from the second door body member 122, or when the first stop member 91 separates from the first door body member 121, the second stop member 92 contacts the second door body member 122. Thereby, the first stop member 91 and the second stop member 92 respectively correspond to the first door body member 121 and the second door body member 122, and can selectively open the first cavity 111 and the second cavity 112 of the dust storage chamber 11.

[0227] In an embodiment of the present disclosure, the dust storage chamber 11 includes a first cavity 111 and a second cavity 112. The first cavity 111 has a first opening 1111, and the second cavity 112 has a second opening 1121 and a third opening 1122 that are separated from each other. The second opening 1121 communicates with a portion of the second cavity 112 outside the cyclone separator 13, and the third opening 1122 communicates with a portion of the second cavity 112 inside the cyclone separator 13. That is, the dust storage chamber 11 is regarded as having three cavities. The door body 12 includes a first door body member 121 and a second door body member 122. The first door body member 121 corresponds to the first opening 1111, and the second door body member 122 corresponds to the second opening 1121 and the third opening 1122 simultaneously.

[0228] After the cleaning robot is combined with the cleaning base station, when the first stop member 91 abuts against the first door body member 121, the cleaning base station can suck the dust in the second cavity 112 into the dust barrel 4. When the motor 931 operates and the second stop member 92 abuts against the second door body member 122, the cleaning base station can suck the dust in the first cavity 111 into the dust barrel 4. Alternatively, after the cleaning robot is combined with the cleaning base station, when the second stop member 92 abuts against the second door body member 122, the cleaning base station can suck the dust in the first cavity 111 into the dust barrel 4. When the motor 931 operates and the first stop member 91 abuts against the first door body member 121, the cleaning base station can suck the dust in the second cavity 112 into the dust barrel 4. Since the first cavity 111 and the second cavity 112 are each open, the area is relatively small. When the negative pressure does not change, the suction force increases, and the cleaning base station can collect the dust in the cleaning robot more cleanly.

[0229] In an embodiment of the present disclosure, the stop member 9 may include a first microswitch and a second microswitch. The first microswitch and the second microswitch are provided on the pile body 1. When the first stop member 91 moves to a predetermined position, that is, when the first stop member 91 moves to the first position, the first stop member 91 activates the first microswitch to stop the operation of the motor 931. When the first stop member 91 moves to the second position, the first stop member 91 activates the second microswitch to stop the operation of the motor 931. Thereby, the stop member 9 can reliably open and close the door body 12. Alternatively, the second stop member 92 may correspond to the first microswitch and the second microswitch, but is not particularly limited thereto.

[0230] As an alternative embodiment of the present disclosure, the first stop member 91 and the second stop member 92 may be driven by two independent drive mechanisms.

[0231] In an embodiment of the present disclosure, as shown in FIGS. 30 and 31, the suction member 94 is provided on the pile body 1. After the door body 12 opens the dust storage chamber 11, the suction member 94 sucks the door body 12 to fix the door body 12, so that the dust box 10 can be reliably opened.

[0232] In an embodiment of the present disclosure, the suction member 94 is used to magnetically adsorb the door body 12 to fix the door body 12. A magnetic structure may be provided on the door body 12, or the door body 12 itself may be a magnetic structure. There may be at least two suction members 94, and the first door body member 121 and the second door body member 122 can conveniently correspond to at least one suction member 94.

[0233] The dust box, the cleaning device, and the cleaning system provided by the embodiments of the present disclosure can improve the dust collection performance of the dust box and the cleaning effect of the cleaning device.

[0234] According to one aspect of the present disclosure, a dust box is provided, a first cavity having a dust inlet, A second cavity having an air outlet, and a transfer passage, wherein the first cavity communicates with the second cavity through the transfer passage.

[0244] According to another aspect of the present disclosure, a dust box is provided, a first cavity having a dust inlet, and a second cavity having an air outlet, a transition passage, the first cavity communicating with the second cavity through the transition passage, and a cyclone separator provided in the second cavity. Here, the extended length of the transition passage is greater than the minimum wall thickness between the first cavity and the second cavity.

[0245] In some embodiments, the transition passage substantially abuts the second cavity.

[0246] In some embodiments, the side wall of the transition passage includes a curved surface.

[0247] In some embodiments, the dust box includes a base, a bottom cover provided on the base and forming the first cavity and the second cavity together with the base, and a door body movably provided on the bottom cover to open and close the first cavity and the second cavity.

[0248] In some embodiments, the bottom cover is detachably provided on the base.

[0249] In some embodiments, the dust box further includes a locking member provided on the base and movably provided with respect to the bottom cover to be spaced apart from or connected to the bottom cover.
