[0050] The floor brush assembly includes a limit release component, and the base station includes a trigger component.

[0055] The technical solution provided in this work can achieve the following beneficial effects:

[0056] The floor brush assembly provided in this invention includes: a roller brush body, a scraper, a drive unit, and a limiting member. The roller brush body is used to clean the surface to be cleaned, the drive unit is used to drive the scraper to switch between a first working position, a second working position, and a self-cleaning position, and the limiting member has a first state and a second state.

[0057] When the limiting component is in the first state, the scraper can only switch from the first working position to the second working position, but cannot switch from the second working position to the self-cleaning position. This design prevents the scraper from being driven to the self-cleaning position during operation, which would affect the cleaning effect. It also ensures that the scraper can accurately move to the second working position when driven by the driver, further guaranteeing the cleaning effect. Simultaneously, this design also prevents the scraper from being impacted by obstacles during operation, thus avoiding excessive force when switching to the self-cleaning position. This prevents the scraper from colliding with other structural components and causing damage, thereby increasing the service life of the scraper and other structural components, and improving the overall reliability of the floor brush assembly.

[0058] When the limiting member is in the second state, the scraper can switch between the second working position and the self-cleaning position. This design allows the scraper to be released by the limiting member when it is not working and self-cleaning is required, ensuring a smooth transition to the self-cleaning position. Furthermore, since the scraper is not working at this time, it is generally not subjected to significant impact, resulting in less force when switching to the self-cleaning position. This prevents the scraper from colliding with other structural components, thus extending the lifespan of the scraper and other components and ensuring the overall reliability of the floor brush assembly.

[0073] As shown in Figures 1 to 8, this invention first provides a floor brush component 1. The floor brush component 1 can be installed on a cleaning device 01, which may include, but is not limited to, a robot vacuum cleaner, a floor scrubber, or a sweeping machine.

[0074] The floor brush assembly 1 may include: a roller brush body 10, a scraper 11, a drive member 19, and a limiting member 12. The roller brush body 10 is used to clean the surface to be cleaned. The scraper 11 may be disposed adjacent to the roller brush body 10, and the end of the scraper 11 may have a first working position spaced apart from the surface to be cleaned, a second working position in contact with the surface to be cleaned, and a self-cleaning position in contact with the roller brush body 10. The drive shaft of the drive member 19 may be drively connected to the scraper 11 to drive the scraper 11 to switch between the first working position, the second working position, and the self-cleaning position. The limiting member 12 may be selectively located on the movement path of the scraper 11, and the limiting member 12 may have a first state and a second state.

[0075] When the limiting member 12 is in the first state, the scraper 11 can be driven to switch from the first working position to the second working position, but cannot switch from the second working position to the self-cleaning position. When the limiting member 12 is in the second state, the scraper 11 can be driven to switch from the second working position to the self-cleaning position.

[0076] It should be noted that when the end of the scraper 11 is in the first working position, the end of the scraper 11 does not contact the roller brush body 10.

[0077] When the limiting member 12 is in the first state, the scraper 11 can only switch from the first working position to the second working position, but cannot switch from the second working position to the self-cleaning position. This setting can prevent the scraper 11 from being driven by the drive member 19 to switch to the self-cleaning position during operation, thus affecting the cleaning effect of the scraper 11. It can also ensure that the scraper 11 can accurately move to the second working position when driven by the drive member 19, thereby further ensuring the cleaning effect of the scraper 11. At the same time, this setting can also prevent the scraper 11 from being impacted by obstacles during operation and switching to the self-cleaning position. This can also prevent the scraper 11 from being subjected to excessive force when switching to the self-cleaning position, thereby preventing the scraper 11 from colliding with other structural components and causing damage to the scraper 11 or other structural components. This improves the service life of the scraper 11 and other structural components, and enhances the reliability of the entire floor brush assembly 1.

[0078] When the limiting member 12 is in the second state, the scraper 11 can switch between the second working position and the self-cleaning position. This configuration allows the scraper 11 to be released by the limiting member 12 when it is not working and needs self-cleaning, ensuring that the scraper 11 can smoothly switch to the self-cleaning position for self-cleaning. Furthermore, since the scraper 11 is not working at this time, it is generally not subjected to significant impact force, resulting in less force when switching to the self-cleaning position. This prevents the scraper 11 from colliding with other structural components, thus extending the service life of the scraper 11 and other structural components, and ensuring the overall reliability of the floor brush assembly 1.

[0079] Optionally, as shown in Figures 1 to 7, the scraper 11 may include a first limiting structure 111. The limiting member 12 may include a second limiting structure 121. When the limiting member 12 is in the first state, the first limiting structure 111 and the second limiting structure 121 can cooperate to limit the scraper 11 so that it cannot switch from the second working position to the self-cleaning position.

[0080] In one embodiment, the first limiting structure 111 may include a limiting groove 112, and the second limiting structure 121 may include an extension plate 122 and a limiting hook 123 disposed at the end of the extension plate 122. When the limiting member 12 is in the first state, the limiting hook 123 can extend into the limiting groove 112. If the scraper 11 tends to switch to the self-cleaning position, the limiting hook 123 and the inner wall of the limiting groove 112 will abut against each other, so as to generate a self-locking torque, thereby preventing the scraper 11 from switching to the self-cleaning position. In this way, the limiting member 12 can be used to limit the scraper 11.

[0081] Meanwhile, when the first limiting structure 111 includes a limiting groove 112 and the second limiting structure 121 includes a limiting hook 123, the cooperation of the limiting groove 112 and the limiting hook 123 can reduce the probability of disengagement when the first limiting structure 111 and the second limiting structure 121 are engaged, thereby ensuring the stability of the limiting member 12 in limiting the scraper 11.

[0082] Optionally, when the inner walls of the limiting hook 123 and the limiting groove 112 abut against each other, the direction of the self-locking torque generated between the limiting hook 123 and the inner walls of the limiting groove 112 can be a first direction X, which can be the direction in which the scraper 11 points towards the surface to be cleaned. Since the end of the scraper 11 needs to move away from the surface to be cleaned when the scraper 11 switches from the second working position to the self-cleaning position, and the direction of the self-locking torque is the direction in which the scraper 11 points towards the surface to be cleaned, the movement direction of the end of the scraper 11 is opposite to the direction of the self-locking torque. Therefore, the movement of the end of the scraper 11 can be restricted by the self-locking torque, thereby effectively preventing the scraper 11 from switching from the second working position to the self-cleaning position.

[0083] Optionally, the extension plate 122 may have an extension portion to allow the limiting groove 112 to have a movable space relative to the limiting hook 123 when the limiting member 12 is in the first state. That is, it can be understood that when the limiting member 12 is in the first state, the scraper 11 can use this movable space to make a small-amplitude movement, so that the scraper 11 can switch from the first working position to the second working position, or from the second working position to the first working position, so that the floor brush assembly 1 can arbitrarily switch the scraper 11 between the first working position and the second working position according to the cleaning needs. That is, when cleaning is not required using the scraper 11, the scraper 11 can be switched to the first working position without the restriction of the limiting member 12; when cleaning is required using the scraper 11, the scraper 11 can also be switched to the second working position without the restriction of the limiting member 12. At the same time, when the scraper 11 is working in the second working position, if it encounters an obstacle, it can also use the impact force of the obstacle to switch back to the first working position, thereby reducing the probability of damage to the scraper 11.

[0084] Optionally, as shown in Figures 1 to 7, the floor brush assembly 1 may further include a limit release member 13. The limit release member 13 may be connected to the limit member 12, and the limit release member 13 may be configured to disengage the limit hook 123 from the limit groove 112 after being subjected to force, so that the limit member 12 switches to the second state.

[0085] Optionally, as shown in Figures 1 to 5, the floor brush assembly 1 may further include a floor brush cover 14. A scraper 11 may be mounted on the floor brush cover 14, and the scraper 11 may be rotatable relative to the floor brush cover 14 to switch between a first working position, a second working position, and a self-cleaning position.

[0086] For example: when the scraper 11 needs to switch from the first working position to the second working position, the drive member 19 can drive the scraper 11 to rotate towards the roller brush body 10, so that the end face of the scraper 11 contacts the surface to be cleaned, thereby performing cleaning work using the scraper 11. When the scraper 11 needs to switch from the second working position to the self-cleaning position, the drive member 19 can continue to drive the scraper 11 to rotate towards the roller brush body 10, so that the roller brush body 10 cleans the scraper 11. When the scraper 11 needs to switch from the self-cleaning position to the second working position, the drive member 19 can drive the scraper 11 to rotate away from the roller brush body 10, so that the end of the scraper 11 contacts the surface to be cleaned. When the scraper 11 does not need to work or self-clean, the drive member 19 can drive the scraper 11 to continue to rotate away from the roller brush body 10, so that the scraper 11 switches from the second working position to the first working position, so that the end of the scraper 11 moves away from the surface to be cleaned.

[0087] The aforementioned limiting member 12 can be installed on the brush cover 14, and the limiting member 12 can rotate relative to the brush cover 14 to switch between a first state and a second state. For example, when the limiting member 12 needs to limit the scraper blade 11, the limiting member 12 can rotate relative to the brush cover 14, causing the limiting member 12 to switch to the first state, at which time the first limiting structure 111 and the second limiting structure 121 are engaged in limiting cooperation. When the limiting member 12 needs to release the scraper blade 11, the limiting member 12 can rotate in the opposite direction, causing the limiting member 12 to switch to the second state, at which time the first limiting structure 111 and the second limiting structure 121 separate to release the scraper blade 11.

[0088] Optionally, the extension plate 122 can be installed on the brush cover plate 14 and can be positioned adjacent to the scraper strip 11. The extension plate 122 can rotate relative to the brush cover plate 14 so that the limiting hook 123 can extend into the limiting groove 112. For example, when the limiting member 12 needs to limit the scraper strip 11, the extension plate 122 can rotate relative to the brush cover plate 14 so that the limiting hook 123 extends into the limiting groove 112. When the limiting member 12 needs to release the scraper strip 11, the extension plate 122 can rotate in the opposite direction so that the limiting hook 123 disengages from the limiting groove 112.

[0089] Optionally, when the scraper blade 11 rotates from the first working position to the second working position, the extension plate 122 can rotate to allow the limiting hook 123 to extend into the limiting groove 112, thereby limiting the scraper blade 11. When the scraper blade 11 rotates from the self-cleaning position to the second working position, the extension plate 122 can rotate to allow the limiting hook 123 to extend into the limiting groove 112, thereby limiting the scraper blade 11.

[0090] The limit release member 13 can be installed on the brush cover plate 14 and can be set adjacent to the limit member 12. The limit release member 13 can rotate relative to the brush cover plate 14, and the limit release member 13 can be configured to rotate relative to the brush cover plate 14 after being subjected to force, and drive the extension plate 122 to rotate, so that the limit hook 123 disengages from the limit groove 112. That is, it can be understood that when it is necessary to limit the scraper blade 11, the extension plate 122 can rotate so that the limit hook 123 extends into the limit groove 112, thereby limiting the scraper blade 11. When the scraper blade 11 needs to switch from the second working position to the self-cleaning position, the limit release member 13 can be operated to rotate in the opposite direction, thereby using the limit release member 13 to drive the extension plate 122 to rotate in the opposite direction, so that the limit hook 123 disengages from the limit groove 112, so that the scraper blade 11 can rotate from the second working position to the self-cleaning position.

[0091] Optionally, as shown in Figures 1 to 7, the floor brush assembly 1 may further include a rotating shaft 16. The rotating shaft 16 can be rotatably connected to the floor brush cover plate 14, and the extension plate 122 and the limit release member 13 can both be fixedly connected to the rotating shaft 16. With this configuration, the limit release member 13 can drive the extension plate 122 to rotate synchronously through the rotating shaft 16.

[0092] Optionally, the limit release member 13 can be directly connected to the extension plate 122 so that the limit release member 13 can drive the extension plate 122 to rotate synchronously.

[0093] Optionally, as shown in Figures 2 and 5, the floor brush cover 14 may include a cover portion 141 and a first mounting plate 142. The scraper blade 11 can be rotatably connected to the cover portion 141; the first mounting plate 142 can be disposed on the cover portion 141, and the rotating shaft 16 can be rotatably connected to the first mounting plate 142. In this embodiment, by setting the first mounting plate 142, a stable mounting and support position can be provided for the rotating shaft 16.

[0094] The rotating shaft 16 can pass through the first mounting plate 142, and the limiting member 12 and the limiting release member 13 can be respectively installed on both sides of the first mounting plate 142. In this way, the first mounting plate 142 can be used to separate the limiting member 12 and the limiting release member 13, so as to avoid positional interference between the limiting member 12 and the limiting release member 13, and also to avoid the limiting release member 13 affecting the limiting operation of the limiting member 12.

[0095] The projection of the limit release member 13 in the first direction X may not overlap with the projection of the wiper strip 11 in the first direction X. That is, it can be understood that there is a gap between the projection of the limit release member 13 in the first direction X and the projection of the wiper strip 11 in the first direction X. This arrangement allows the limit release member 13 to be closer to the edge of the floor brush assembly 1, thereby avoiding positional interference between the limit release member 13 and the wiper strip 11, and facilitating the operation of the limit release member 13.

[0096] Optionally, the floor brush cover 14 may further include a second mounting plate 143. The second mounting plate 143 may be disposed on the cover portion 141 and opposite to the first mounting plate 142. The rotating shaft 16 may pass through the first mounting plate 142 and the second mounting plate 143 and be rotatably connected to the first mounting plate 142 and the second mounting plate 143. The limiting member 12 may be located between the first mounting plate 142 and the second mounting plate 143. With this arrangement, the first mounting plate 142 and the second mounting plate 143 can provide two support positions for the rotating shaft 16, making the installation of the rotating shaft 16 more stable. At the same time, this arrangement can use the first mounting plate 142 and the second mounting plate 143 to protect the limiting member 12 from damage caused by impacts from obstacles.

[0097] As shown in Figures 1 to 7, the floor brush assembly 1 may further include a reset member 15. The reset member 15 can be connected to or abut against the extension plate 122, and can be configured to provide a force to switch the limiting member 12 from a second state to a first state, thereby switching the limiting member 12 from the second state to the first state. For example, when it is necessary to limit the scraper 11, the reset member 15 can apply a reset force to the extension plate 122 to rotate the extension plate 122, thereby causing the limiting hook 123 to extend into the limiting groove 112. Thus, by providing the limiting release member 13 and the reset member 15, this invention allows the limiting member 12 to switch arbitrarily between the first state and the second state.

[0098] Optionally, the aforementioned reset element 15 can be an elastic element, which can have a restoring force when the limiting element 12 is in the second state. Thus, the restoring force inside the elastic element can be applied to the limiting element 12, causing the limiting element 12 to automatically switch from the second state to the first state. However, this is not a limitation; the reset element 15 may not be an elastic element, but may be other components, which can be selected and set according to actual needs, all of which are within the scope of protection of this invention.

[0099] Optionally, the reset member 15 can be a torsion spring. The torsion spring may include a body portion 153, a connecting portion 154, and a reset portion 155. The body portion 153 can be sleeved on the rotating shaft 16 and located between the limiting release member 13 and the extension plate 122. This arrangement allows the rotating shaft 16 to provide a stable position for the body portion 153 of the torsion spring, thus limiting the torsion spring and preventing positional displacement or detachment during deformation or recovery.

[0100] The connecting part 154 can be located at one end of the main body 153, and the connecting part 154 can be connected to the floor brush cover 14. The reset part 155 can be located at the other end of the main body 153, and the reset part 155 can be connected to or abut against the extension plate 122. Thus, when the limiting member 12 is switched to the second state, the torsion spring can twist, so that the torsion spring has a restoring force inside. When it is necessary to switch the limiting member 12 to the first state, the torsion spring can return to the initial state, so that its internal restoring force is applied to the extension plate 122, thereby driving the extension plate 122 to rotate, so that the limiting member 12 switches from the second state to the first state.

[0101] The torsion spring can be disposed between the first mounting plate 142 and the second mounting plate 143, and the connecting part 154 of the torsion spring can be connected to the first mounting plate 142 and / or the second mounting plate 143. This arrangement provides a stable mounting position and support point for the torsion spring using the first mounting plate 142 and / or the second mounting plate 143.

[0102] Optionally, as shown in Figures 2 and 4, the torsion spring may include a first torsion spring 151 and a second torsion spring 152. The first torsion spring 151 and the second torsion spring 152 may be located on both sides of the extension plate 122, respectively. With this configuration, the first torsion spring 151 and the second torsion spring 152 can simultaneously apply restoring forces to the extension plate 122 from both sides, making the movement of the limiting member 12 more stable when switching states and improving the accuracy of the limiting member 12 in switching states.

[0103] The body portion 153 of the first torsion spring 151 and the body portion 153 of the second torsion spring 152 can both be sleeved on the rotating shaft 16. Furthermore, the body portion 153 of the first torsion spring 151 and the body portion 153 of the second torsion spring 152 can both be located between the first mounting plate 142 and the second mounting plate 143, so that the first torsion spring 151 and the second torsion spring 152 can be connected or abutted against the extension plate 122, and so that the first torsion spring 151 and the second torsion spring 152 can easily apply a restoring force to the extension plate 122.

[0104] Optionally, the connecting portion 154 of the first torsion spring 151 can be connected to the first mounting plate 142, and the connecting portion 154 of the second torsion spring 152 can be connected to the second mounting plate 143. This arrangement allows the first mounting plate 142 and the second mounting plate 143 to provide a stable mounting position and support point for the first torsion spring 151 and the second torsion spring 152 respectively, and avoids positional interference between the first torsion spring 151 and the second torsion spring 152 during installation.

[0105] The reset portion 155 of the first torsion spring 151 and the reset portion 155 of the second torsion spring 152 can be an integral structure. The reset portions 155 of the first torsion spring 151 and the reset portions 155 of the second torsion spring 152 can be connected to each other. This can further ensure that the restoring force applied by the first torsion spring 151 and the second torsion spring 152 to the extension plate 122 can reach the extension plate 122 at the same time, so as to further improve the stability of the movement of the limiting member 12 when switching states and further improve the accuracy of the limiting member 12 when switching states.

[0106] However, it is not limited to this. The reset part 155 of the first torsion spring 151 and the reset part 155 of the second torsion spring 152 can also be a separate structure, and the reset part 155 of the first torsion spring 151 and the reset part 155 of the second torsion spring 152 can be connected to or abut against the limiting member 12 respectively.

[0107] In addition, the reset element 15 may not be a torsion spring, but may be other elastic elements. This invention does not limit this and can be selected and set according to actual needs, all of which are within the protection scope of this invention.

[0108] Optionally, as shown in Figures 1, 2, and 7, the floor brush assembly 1 may further include a first stop 17 and a second stop 18. The first stop 17 can be connected to the rotating shaft 16 and is located on the side of the limiting release member 13 opposite to the second mounting plate 143; the second stop 18 can be connected to the rotating shaft 16 and is located on the side of the second mounting plate 143 opposite to the limiting release member 13. This configuration allows the first stop 17 and the second stop 18 to stop the lateral movement of the rotating shaft 16, preventing it from detaching from the first mounting plate 142 and the second mounting plate 143, thus improving the stability of the floor brush assembly 1.

[0109] At least one of the aforementioned limiting member 12, limiting release member 13, and reset member 15 may be located between the first stop member 17 and the second stop member 18, so as to stop it using the first stop member 17 and the second stop member 18 to prevent it from falling off.

[0110] Optionally, the first stop 17 and the second stop 18 can be nuts, which can be threadedly connected to the rotating shaft 16 to facilitate the installation and removal of the first stop 17 and the second stop 18. However, they are not limited to this; the first stop 17 and the second stop 18 can also be stop plates or the like connected to the rotating shaft 16, and can be selected and set according to actual needs.

[0111] This invention also provides a cleaning device 01. The cleaning device 01 may include, but is not limited to, a robotic vacuum cleaner, a floor scrubber, or a sweeping machine. As shown in Figures 1 to 8, the cleaning device 01 may include: a cleaning main unit 222 and a floor brush assembly 1. The floor brush assembly 1 may be the aforementioned floor brush assembly 1, and the floor brush assembly 1 may be installed on the cleaning main unit.

[0112] It should be noted that the specific structure and beneficial effects of the floor brush component 1 have been described in detail in this work. Therefore, the specific structure and beneficial effects of the floor brush component 1 will not be repeated here. Please refer to the detailed description in the preceding content. All of this is within the protection scope of this work.

[0113] The cleaning device 01 provided by this invention may include the aforementioned floor brush assembly 1, which includes: a roller brush body 10, a scraper 11, a drive member 19, and a limiting member 12. The roller brush body 10 is used to clean the surface to be cleaned, the drive member 19 is used to drive the scraper 11 to switch between a first working position, a second working position, and a self-cleaning position, and the limiting member 12 has a first state and a second state.

[0114] When the limiting member 12 is in the first state, the scraper 11 can only switch from the first working position to the second working position, but cannot switch from the second working position to the self-cleaning position. This design prevents the scraper 11 from being driven by the drive member 19 to switch to the self-cleaning position during operation, thus affecting its cleaning effect. It also ensures that the scraper 11 can accurately move to the second working position when driven by the drive member 19, further guaranteeing its cleaning effect. Simultaneously, this design also prevents the scraper 11 from being impacted by obstacles during operation, thus avoiding excessive force when switching to the self-cleaning position. This prevents the scraper 11 from colliding with other structural components and causing damage, thereby increasing the service life of the scraper 11 and other structural components, and improving the overall reliability of the cleaning equipment.

[0115] When the limiting member 12 is in the second state, the scraper 11 can switch between the second working position and the self-cleaning position. This configuration allows the scraper 11 to be released by the limiting member 12 when it is not working and needs self-cleaning, ensuring that the scraper 11 can smoothly switch to the self-cleaning position for self-cleaning. Furthermore, since the scraper 11 is not working at this time, it is generally not subjected to significant impact force, resulting in less force when switching to the self-cleaning position. This prevents the scraper 11 from colliding with other structural components, thus extending the service life of the scraper 11 and other structural components, and ensuring the overall reliability of the floor brush assembly 1.

[0116] This invention also provides a cleaning system 03. As shown in Figure 8, the cleaning system 03 may include a base station 02 and a cleaning device 01. The cleaning device 01 may be the cleaning device described above, and the cleaning device 01 may be connected to the base station 02 to charge or clean the cleaning device 01 using the base station 02.

[0117] It should be noted that the specific structure and beneficial effects of the cleaning equipment 01 have been described in detail in this work, so the specific structure and beneficial effects of the cleaning equipment 01 will not be repeated here. Please refer to the specific description in the preceding content, which are all within the protection scope of this work.

[0118] The cleaning system 03 provided by this invention includes the aforementioned cleaning device 01, as shown in Figures 1 to 8. The cleaning device 01 includes a floor brush assembly 1, which includes a roller brush body 10, a scraper 11, a drive unit 19, and a limiting member 12. The roller brush body 10 is used to clean the surface to be cleaned, the drive unit 19 is used to drive the scraper 11 to switch between a first working position, a second working position, and a self-cleaning position, and the limiting member 12 has a first state and a second state.

[0119] When the limiting member 12 is in the first state, the scraper 11 can only switch from the first working position to the second working position, but cannot switch from the second working position to the self-cleaning position. This design prevents the scraper 11 from being driven by the drive member 19 to switch to the self-cleaning position during operation, thus affecting the cleaning effect of the scraper 11. It also ensures that the scraper 11 can accurately move to the second working position when driven by the drive member 19, further guaranteeing the cleaning effect of the scraper 11. Simultaneously, this design also prevents the scraper 11 from being impacted by obstacles during operation, thus avoiding excessive force when switching to the self-cleaning position. This prevents the scraper 11 from colliding with other structural components and causing damage, thereby increasing the service life of the scraper 11 and other structural components, and improving the overall reliability of the cleaning system.

[0120] When the limiting member 12 is in the second state, the scraper 11 can switch between the second working position and the self-cleaning position. This configuration allows the scraper 11 to be released by the limiting member 12 when it is not working and self-cleaning is required, ensuring that the scraper 11 can smoothly switch to the self-cleaning position for self-cleaning. Furthermore, since the scraper 11 is not working at this time, it is generally not subjected to significant impact force, resulting in less force when switching to the self-cleaning position. This prevents the scraper 11 from colliding with other structural components, thus extending the service life of the scraper 11 and other structural components, and ensuring the reliability of the entire cleaning system.

[0121] Optionally, as shown in Figures 1, 2, and 4, the floor brush assembly 1 may include a limit release member 13. The base station may include a trigger member 2. When the cleaning equipment is connected to the base station, the trigger member 2 can contact the limit release member 13 and apply an unlocking force to the limit release member 13, so as to cause the limit release member 13 to switch the limit member 12 from the first state to the second state. This configuration can improve the automation level of the cleaning system, eliminating the need for operators to manually operate the limit release member 13, thereby freeing up manpower.

[0122] The drive unit 19 can be configured to switch the scraper 11 between a second working position and a self-cleaning position in response to the docking status of the cleaning equipment and the base station. That is: when the cleaning equipment is docked with the base station, the drive unit 19 can respond to the signal that the cleaning equipment has successfully docked with the base station, at which time the drive unit 19 can drive the scraper 11 to switch from the second working position to the self-cleaning position; when the cleaning equipment is disconnected from the base station, the drive unit 19 can respond to the signal that the cleaning equipment has been disconnected from the base station, at which time the drive unit 19 can drive the scraper 11 to switch from the self-cleaning position to the second working position.

[0123] Optionally, one of the trigger 2 and the limit release member 13 has a Hall sensor, and the other has a magnet. When the cleaning device is docked with the base station, the magnet contacts the Hall sensor and generates a first trigger signal. The drive member 19 can respond to the first trigger signal and drive the scraper 11 to move from the second working position to the self-cleaning position; and / or when the cleaning device is separated from the base station, the magnet separates from the Hall sensor and generates a second trigger signal. The drive member 19 can respond to the second trigger signal and drive the scraper 11 to move from the self-cleaning position to the second working position.
