[0042] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0043] The present invention provides a cleaning robot 100. Please refer to Figures 1 to 5 , the cleaning robot 100 includes a robot main body 30, a dust box assembly 10, and a power assembly 20.

[0044] The robot main body 30 includes components such as a chassis (not marked), two drive wheels (not marked), a universal wheel (not marked), a suction device (not shown in the figure), etc. The two drive wheels are respectively arranged on the left and right sides of the chassis and are used to drive the autonomous movement of the robot main body. The universal wheel is arranged at the front or the tail of the robot main body 30, and the suction device is installed on the chassis and is used to drive the flow of air.

[0045] The dust box assembly 10 includes a dust box main body 11. The dust box main body 11 is provided with a dust inlet 117, a dust outlet 111, and a dust collection cavity 112 that communicates with both the dust inlet 117 and the dust outlet 111. The dust collection cavity 112 is also communicated with the suction device so that external dust, paper scraps and other sundries can enter the dust collection cavity 112 through the dust inlet 117.

[0046] It should be noted that the dust box assembly 10 and the suction device are both installed on the chassis. The dust collection chamber 112 in the dust box assembly 10 is communicated with the suction device. The suction device drives the air flow in the dust collection chamber 112 to drive the dust inlet 117 to continuously suck in external dust, paper scraps and other sundries.

[0047] The cleaning robot 100 further includes a filter screen. The filter screen is located at the connection between the suction device and the dust collection chamber 112. It can be installed in the dust collection chamber 112 or at the suction end of the suction device. Here, they will not be listed one by one. The suction device sucks air through the filter screen to prevent external dust, paper scraps and other sundries from entering the suction device. It should be noted that the filter screen cannot be installed at the connection between the dust inlet 117 and the dust outlet 111, that is, during the process of dust, paper scraps and other sundries being discharged from the dust inlet 117 to the dust outlet 111, they do not pass through the filter screen, so as to ensure that the dust, paper scraps and other sundries entering from the dust inlet 117 can be smoothly discharged from the dust outlet 111.

[0048] There are many positional relationships among the dust inlet 117, the dust outlet 111 and the filter screen. For example, both the dust inlet 117 and the dust outlet 111 are provided at the bottom of the dust box body 11, and the filter screen is provided at the top of the dust box body 11; another example is that the dust inlet 117 is provided on one side of the dust box body 11, and the dust outlet 111 and the filter screen are both provided on the other side of the dust box body 11.

[0049] The dust box assembly 10 further includes a movable plate 12. The movable plate 12 is rotatably installed on the dust box body 11 and can open or cover the dust outlet 111.

[0050] There are many ways for the movable plate 12 to be rotatably connected to the dust box body 11. For example, the movable plate 12 is rotatably connected to the dust box body 11 through a shaft; another example is that the movable plate 12 is rotatably connected to the dust box body 11 through a hinge.

[0051] There are many positions for the rotation axis of the movable plate 12. It can be located in the middle of the movable plate 12 or on one side of the movable plate 12. Preferably, the rotation axis of the movable plate 12 is located on one side of the movable plate 12.

[0052] When the movable plate 12 rotates relative to the dust box body 11, it can rotate towards the inside of the dust collection chamber 112 or towards the outside of the dust collection chamber 112. Preferably, the movable plate 12 rotates towards the outside of the dust collection chamber 112, so as to prevent the movable plate 12 from blocking the discharge of dust in the dust collection chamber 112.

[0053] The movable plate 12 is provided with an operating part 122, and the operating part 122 is used to receive the drive of the power assembly 20 to drive the movable plate 12 to flip relative to the dust box body 11 to an open or closed state of the dust discharge port 111. The operating part 122 can be a rod-like structure connected to the movable plate 12, or the operating part 122 can also be a gear-like structure connected to the movable plate 12, which can be set according to actual needs.

[0054] The power assembly 20 can be installed on the robot main body 30 or the dust box body 11. The power assembly 20 can be used to drive the operating part 122 on the movable plate 12 so that the movable plate 12 can be switched between the positions of opening the dust discharge port 111 and closing the dust discharge port 111.

[0055] The power assembly 20 can be a component composed of a motor and a transmission rod, or the power assembly 20 can also be a component composed of a pneumatic pump, a cylinder, a piston, and a piston rod. The power assembly 20 can also be other components capable of generating driving force, which will not be listed one by one here.

[0056] The power assembly 20 can be installed on the robot main body 30 or the dust box body 11. Preferably, the power assembly 20 is installed on the robot main body 30, so that the space of the dust collection cavity 112 of the dust box body 11 can be maximally set, and thus more dust can be stored.

[0057] The above-mentioned cleaning robot 100 has two states, namely a dust suction state and a dust discharge state.

[0058] When the cleaning robot 100 is in the dust suction state, the cleaning robot 100 travels on the ground under the action of the driving wheels. At this time, the dust discharge port 111 is covered by the movable plate 12. The suction device drives the air in the environment to pass through the dust inlet 117, the dust collection cavity 112, and the suction device in sequence and then discharges it to the environment. When the air is inhaled into the dust collection cavity 112, dust, paper scraps and other sundries on the ground also enter the dust collection cavity 112 together with the air, thereby realizing the cleaning of the ground. At the same time, the dust, paper scraps and other sundries in the dust collection cavity 112 are blocked by the filter screen and temporarily stay in the dust collection cavity 112.

[0059] When the cleaning robot 100 is in the dust discharge state, please refer to Figure 2 , the power assembly 20 drives the operating part 122, and the movable plate 12 starts to rotate under the action of the operating part 122, thereby opening the dust discharge port 111. The dust, paper scraps and other sundries in the dust collection cavity 112 are sucked out from the dust discharge port 111 by the garbage collection base station 200, thereby completing the evacuation of the dust, paper scraps and other sundries in the dust collection cavity 112.

[0060] In other embodiments, the user can also manually apply an external drive to the operation part 122 to cause the movable plate 12 to flip relative to the dust box body 11. When the user needs to empty the garbage in the dust box body 11, the user can manually operate the operation part 122 to drive the movable plate 12 to rotate to a position where the dust discharge port 111 is opened, so that there is no need to open the dust box cover, and the operation of emptying the garbage is simpler and more convenient. Among them, the dust discharge port 111 can be designed with a suitable shape and a sufficiently large size according to the need of emptying the garbage. The movable plate 12 and the dust discharge port 111 are both located at the bottom or side or top of the dust box body 11.

[0061] In an embodiment of the present invention, please refer to Figure 1 , the movable plate 12 includes a cover main body 121 and a swing rod 122a. The cover main body 121 is rotatably connected to the dust box body 11. The rotation shaft 121a of the cover main body 121 is located on one side of the dust discharge port 111. One end of the swing rod 122a is fixed to the rotation shaft 121a of the cover main body 121, and the other end is spaced from the cover main body 121. The swing rod 122a forms the operation part 122. With such a setting, when the cover main body 121 is rotated by the same angle, compared with the swing rod 122a connected to the end of the cover main body 121 far from the rotation shaft 121a, the movement distance of the swing rod 122a connected to the rotation shaft 121a of the cover main body 121 by the push rod 22 is reduced, thereby reducing the space for the swing rod 122a to move and increasing the utilization rate of the space.

[0062] The cover main body 121 and the swing rod 122a can be integrally formed, and the two can be fixedly connected by bolts, and the two can also be fixedly connected by welding, which will not be listed one by one here.

[0063] There are many connection positions between the swing rod 122a and the cover main body 121. For example, the swing rod 122a is connected to the middle of the cover main body 121, which will not be listed one by one here.

[0064] Further, the extending direction of the swing rod 122a is perpendicular to the rotation shaft 121a of the cover main body 121, and the extending direction of the swing rod 122a is set at an acute angle with the plane where the cover main body 121 is located. With such a setting, the force required for the cover main body 121 to rotate is the force perpendicular to the rotation shaft 121a of the cover main body 121. The extending direction of the swing rod 122a is perpendicular to the rotation shaft 121a of the cover main body 121, which is more convenient to receive the force perpendicular to the rotation shaft 121a of the cover main body 121.

[0065] In order to provide a force for the movable plate 12 to switch from the state of opening the dust discharge port 111 to the state of covering the dust discharge port 111, in an embodiment of the present invention, please refer to Figure 3, the dust box assembly 10 further includes an elastic reset member 13, and the elastic reset member 13 is elastically connected to the movable plate 12 and the dust box main body 11. There are many types of elastic reset members 13, which can be components that can provide elastic force such as torsion springs and elastic ropes. There are many positions for the elastic reset member 13. For example, one end of the elastic reset member 13 is connected to the dust box main body 11, and the other end is connected to the end of the movable plate 12 away from the rotating shaft 121a; another example is that one end of the elastic reset member 13 is connected to the dust box main body 11, and the other end is connected to the rotating shaft 121a of the cover main body 121. There are many connection methods between the elastic reset member 13 and the dust box main body 11 and the movable plate 12, which can be bonding, snap connection, etc.

[0066] When the movable plate 12 is switched from the state of covering the dust discharge port 111 to the state of opening the dust discharge port 111, the elastic reset member 13 is gradually stretched or compressed, so as to provide a force for the movable plate 12 to switch from the state of opening the dust discharge port 111 to the state of covering the dust discharge port 111. Of course, the elastic reset member 13 can still have elastic force when the movable plate 12 is in the state of covering the dust discharge port 111, so as to provide a force for the movable plate 12 to maintain the state of covering the dust discharge port 111.

[0067] In other embodiments, the extending direction of the swing rod 122a is parallel to the rotating shaft 121a of the cover main body 121, or the extending direction of the swing rod 122a is arranged at an angle with the rotating shaft 121a of the cover main body 121, which can be set according to actual needs.

[0068] Furthermore, in order to better cover the dust discharge port 111, please refer to Figure 1 , Figure 4 and Figure 5 , the dust box main body 11 is provided with a protruding portion 113 surrounding the periphery of the dust discharge port 111 on the outside, the movable plate 12 is provided with a sealing layer 123, and the movable plate seals the dust discharge port by adapting the sealing layer to the protruding portion. There are many materials for the sealing layer, which can be silicone, sponge, plastic, etc.

[0069] Optionally, the sealing layer 123 forms a groove on the surface, and the sealing layer 123 is in sealing contact with the protruding portion 113 by adapting the groove to the protruding portion 113. There are many shapes of the groove, which can be trapezoidal, quadrilateral and other shapes.

[0070] Of course, it can also be that the dust box main body 11 is provided with a groove surrounding the axial side of the dust discharge port 111 on the outside, and the movable plate 12 is provided with a protrusion cooperating with the groove to be in sealing contact with the groove.

[0071] In order to better maintain the state of the movable plate 12 covering the dust discharge port 111, in an embodiment of the present invention, please refer to Figure 5, a first magnetic part 14 is arranged on the periphery of the dust outlet 111 of the dust box main body 11, and a second magnetic part 124 is correspondingly arranged on one side of the movable plate 12 close to the dust outlet 111. The second magnetic part 124 and the first magnetic part 14 are magnetically attracted to each other. The first magnetic part 14 and the second magnetic part 124 can be magnets that are magnetically attracted to each other respectively, or the first magnetic part 14 can be a metal and the second magnetic part 124 can be a magnet that cooperates with the metal. Here, they will not be listed one by one.

[0072] For better dust removal effect, in an embodiment of the present invention, please refer to Figure 1 and Figure 3 , the dust box main body 11 has a bottom surface 114 and a first side surface 116 adjacent to the bottom surface 114. The dust inlet 117 is arranged on the first side surface 116, and the dust outlet 111 is arranged on the bottom surface 114. With such a setting, the dust entering from the dust inlet 117 will move towards the position close to the dust outlet 111 under the action of gravity, so that it is more convenient for the dust outlet 111 to completely remove the dust in the dust collection cavity 112.

[0073] Furthermore, please refer to Figure 1 , Figure 3 and Figure 4 , in order to facilitate the movement of the operation part 122 and limit the movement range of the operation part 122, the dust box main body 11 has a second side surface 115 connecting the bottom surface 114 and the first side surface 116. An activity groove 1151 is recessed on the second side surface 115 of the dust box main body 11. The operation part 122 is received in the activity groove 1151, allowing the operation part 122 to swing within a preset angle range.

[0074] Furthermore, please refer to Figure 1 and Figure 4 , in order to facilitate the installation of the power assembly 20, the activity groove 1151 extends towards the bottom surface 114 and penetrates the bottom surface 114, so that the activity groove 1151 has an installation port 1151a formed on the bottom surface 114, so as to access the power assembly 20 through the installation port 1151a, or remove the power assembly 20 through the installation port 1151a.

[0075] In an embodiment of the present invention, please refer to Figure 2 and Figure 3 , the power assembly 20 includes a driving device 21 and a push rod 22 connected to the driving device 21. The driving device 21 is installed on the robot main body 30. The free end of the push rod 22 can be abutted against or separated from the operation part 122. The driving device 21 drives the push rod 22 to rotate, so as to apply a driving force to the operation part 122 and drive the movable plate 12 to flip relative to the dust box main body 11.

[0076] When the driving device 21 does not transmit power, the user can freely take out the dust box assembly 10, remove the power assembly 20 through the installation port 1151a, and separate the dust box assembly 10 from the power assembly 20; the user can also reinstall the dust box assembly 10, and reconnect the dust box assembly 10 to the power assembly 20 by reconnecting the installation port 1151a to the power assembly 20. Moreover, the power assembly 20 does not need to be placed inside the dust box body 11, and there is no need to provide a conductive connection member, which does not occupy the volume of the dust box body 11 and facilitates washing the dust box body 11.

[0077] It should be noted that the driving device 21 can drive the push rod 22 to switch between the initial position and the final position. When the push rod 22 is in the initial position, the movable plate 12 is in the position of covering the dust discharge port 111; when the push rod 22 is in the final position, the movable plate 12 is in the position of opening the dust discharge port 111. The initial position of the push rod 22 is located outside the movable slot 1151, and the push rod 12 is separated from the operation part 122, so that the push rod 12 will not interfere with the dust box assembly 10, and the user can freely take out or install the dust box assembly 10; the initial position of the push rod 22 is located inside the movable slot 1151, and the driving device 21 can drive the push rod 22 to move from the initial position to the final position, that is, drive the push rod 22 to turn into the movable slot 1151 through the driving device 21, so as to push the swing rod 122a to swing relative to the dust box body 11, and then drive the movable plate 12 to rotate to the state of opening the dust discharge port 111.

[0078] Of course, there are many installation positions and movement directions of the driving device 21. For example, the driving device 21 is installed in the dust collection cavity 112 of the dust box assembly 10 to rotate the movable plate 12 towards the outside of the dust collection cavity 112; or the driving device 21 is installed in the dust collection cavity 112 of the dust box assembly 10 to drive the movable plate 12 inside the dust collection cavity 112.

[0079] The driving device 31 is used to provide power for the rotation of the movable plate 12. It can be composed of a motor and a reduction box, or can be composed of a hydraulic system. The driving device 31 can also be composed of other structures.

[0080] Furthermore, please refer to Figure 2 and Figure 3 , the rotation axis of the push rod 22 and the rotation axis of the movable plate 12 are perpendicular to each other, and the rotation axis of the push rod 22 and the rotation axis of the movable plate 12 are offset from each other. The force driving the movable plate 12 to rotate around the rotation axis is the force perpendicular to the rotation axis of the movable plate 12. If the force acting on the movable plate 12 is not perpendicular to the rotation axis of the movable plate 12, a component force in other directions will be generated, squeezing or stretching the movable plate 12, which is likely to reduce the service life of the movable plate 12.

[0081] The present invention also proposes a cleaning robot 100', please refer toFigures 6 to 10 , the cleaning robot 100' includes: a robot main body 20', a dust box main body 30', a movable plate 40', and a power assembly 10'.

[0091] The power assembly 10' can be a component composed of a motor and a transmission rod. The power assembly 10' can also be a component composed of a pneumatic pump, a cylinder, a piston and a piston rod. The power assembly 10' can also be other components capable of generating driving force, and will not be listed one by one here.

[0092] It should be noted that there are many ways for the power assembly 10' to drive the movable plate 40'. For example, please refer to Figure 10, the power assembly 10' includes a motor and a reduction gear fixedly connected to the output shaft of the motor. The output section of the reduction gear is coaxially arranged with the rotating shaft of the movable plate 40'. On one side of the rotating shaft of the movable plate 40' close to the output section, a quadrilateral clamping groove is recessed. At one end of the output section close to the movable plate 40', a quadrilateral clamping protrusion matching the clamping groove is protruded. The motor drives the reduction gear to rotate, and the shaft of the movable plate 40' is driven to rotate by the reduction gear through the clamping connection, so as to realize the rotation of the movable plate 40'; for another example, the power assembly 10' includes a motor and a transmission rod fixedly connected to the output section of the motor. The transmission rod protrudes with a rotation protrusion arranged in a circular shape. On one side surface of the movable plate 40', a rotation groove arranged in a circular shape and matching the rotation protrusion is recessed. The rotation protrusion of the transmission rod extends into the rotation groove of the movable plate 40' to realize the rotational connection between the transmission rod and the movable plate 40'. The rotation of the output section of the motor drives the transmission rod to rotate, and the transmission rod drives the movable plate 40' to rotate through the cooperation of the rotation protrusion and the rotation groove.

[0093] In an embodiment of the present invention, please refer to Figure 6 , the cleaning robot further includes a controller 50', and the controller 50' is electrically connected to the power assembly 10'.

[0094] There are many types of the controller 50', which can be a single-chip microcomputer, a Bluetooth device, etc. When the controller 50' receives the start dust removal instruction, the controller 50' controls the power assembly 10' to drive the movable plate 40' to unfold relative to the dust box body 30'; when the controller 50' receives the end dust removal instruction, the controller 50' controls the power assembly 10' to drive the movable plate 40' to close relative to the dust box body 30'.

[0095] It should be noted that the start dust removal instruction can be an instruction sent by the user to the controller 50', or an instruction sent by a position detection device, such as a Hall sensor, a photoelectric sensor and other sensors with the function of detecting positions, to the controller 50'. The end dust removal instruction can be an instruction sent by the user to the controller 50', or an instruction sent by the photoelectric sensor installed at the dust removal port 32'.

[0096] Further, please refer to Figure 9 and Figure 10 , the power assembly 10' includes a driving device 11' and a push rod 12' connecting the driving device 11'. The driving device 11' is installed on the robot body 20'. The push rod 12' can be linked or separated from the movable plate 40'. The driving device 11' drives the push rod 12' to rotate, so as to drive the movable plate 40' to flip relative to the dust box body 30'.

[0097] The driving device 11' is installed on the robot main body 20'. The push rod 12' and the movable plate 40' can be linked or separated, which enables the detachable connection between the dust box main body 30' and the robot main body 20'. Since the driving device 11' is not provided on the dust box assembly, the waterproof requirement for the dust box assembly is not high. The dust box assembly can be directly immersed in water for cleaning after being detached from the robot main body 20'. At the same time, the driving device 11' is installed on the robot main body 20' without occupying the space inside the dust collection cavity 33', making the space of the dust collection cavity 33' larger.

[0098] Further, please refer to Figure 9 , the rotation axis of the push rod 12' and the rotation axis of the movable plate 40' are perpendicular to each other, and the rotation axis of the push rod 12' and the rotation axis of the movable plate 40' are staggered from each other. The force driving the movable plate 40' to rotate around the rotation axis is the force perpendicular to the rotation axis of the movable plate 40'. If the force acting on the movable plate 40' is not perpendicular to the rotation axis of the movable plate 40', it will generate a component force in other directions, squeezing or stretching the movable plate 40', which is likely to reduce the service life of the movable plate 40'.

[0099] The present invention also proposes a cleaning system 1000. Please refer to Figure 11 , the cleaning system 1000 includes a garbage collection base station 200 and a cleaning robot 100.

Among them, the garbage collection base station 200 is provided with a dust collection port 201, and the dust collection port 201 is used to dock with the dust discharge port 111 of the cleaning robot 100.

[0100] When the cleaning robot 100 needs to discharge dust, the cleaning robot 100 moves towards the garbage collection base station 200 and docks with the dust collection port 201 of the garbage collection base station 200. After the dust discharge port 111 is docked with the dust collection port 201 of the garbage collection base station 200, the controller controls the power assembly 20 to work. The power assembly 20 directly drives the movable plate 12 to open the dust discharge port 111 or drives the operating part 122 to drive the movable plate 12 to open the dust discharge port 111. The garbage collection base station 200 starts to work, and the dust is discharged from the dust collection cavity 112, through the dust discharge port 111 of the dust box main body 11 to the dust collection port 201 of the garbage collection base station 200, and then enters the garbage collection base station 200, completing the cleaning of the dust collection cavity 112 of the cleaning robot 100. This setting can avoid the user from manually cleaning the dust collection cavity 112. At the same time, it can avoid the dust spillage caused by the user manually cleaning the dust collection cavity 112, which not only pollutes the environment again but also has an adverse impact on the user's breathing.
