[0019] In one exemplary embodiment of this disclosure, the limiting release member is installed on the floor brush cover and disposed adjacent to the limiting member. The limiting release member is configured to rotate relative to the floor brush cover after being subjected to force, and drive the extension plate to rotate, so that the limiting hook disengages from the limiting groove.

[0020] In one exemplary embodiment of this disclosure, the floor brush assembly further includes:

[0021] The rotating shaft is rotatably connected to the floor brush cover, and the extension plate and the limiting release component are both fixedly connected to the rotating shaft.

[0022] In one exemplary embodiment of this disclosure, the floor brush assembly further includes:

[0023] A reset member, connected to or abutting the extension plate, is configured to provide a force to switch the limiting member from the second state to the first state.

[0024] In one exemplary embodiment of this disclosure, the reset member is a torsion spring, the torsion spring comprising:

[0025] The main body is sleeved on the rotating shaft and located between the limiting release member and the extension plate;

[0026] A connecting part is located at one end of the main body, and the connecting part is connected to the floor brush cover plate;

[0027] A reset part is located at the other end of the main body, and the reset part is connected to or abuts against the extension plate.

[0028] In one exemplary embodiment of this disclosure, the torsion spring includes:

[0029] First torsion spring component;

[0030] The second torsion spring is located on both sides of the extension plate, and the first torsion spring and the second torsion spring are located on both sides of the extension plate, respectively.

[0031] Wherein, the reset part of the first torsion spring and the reset part of the second torsion spring are separate structures, and the reset parts of the first torsion spring and the reset parts of the second torsion spring are respectively connected to or abut against the limiting member; or, the reset parts of the first torsion spring and the reset parts of the second torsion spring are integral structures, and the reset parts of the first torsion spring and the reset parts of the second torsion spring are interconnected.

[0033] The scraper is rotatably connected to the cover plate portion;

[0034] A first mounting plate is disposed on the cover plate portion; the rotating shaft is rotatably connected to the first mounting plate.

[0035] The second mounting plate is disposed on the cover plate and is opposite to the first mounting plate. The rotating shaft passes through the first mounting plate and the second mounting plate and is rotatably connected to the first mounting plate and the second mounting plate. The limiting member is located between the first mounting plate and the second mounting plate.

[0036] In one exemplary embodiment of this disclosure, the limiting release member is located on the side of the first mounting plate opposite to the second mounting plate.

[0037] In an exemplary embodiment of this disclosure, the projection of the limiting release member in the first direction and the projection of the scraper in the first direction do not overlap;

[0038] Wherein, the first direction is the direction in which the scraper points toward the surface to be cleaned.

[0039] In one exemplary embodiment of this disclosure, the torsion spring is disposed between the first mounting plate and the second mounting plate, and the connecting portion of the torsion spring is connected to the first mounting plate and / or the second mounting plate.

[0040] In one exemplary embodiment of this disclosure, the floor brush assembly further includes:

[0041] The first stop is connected to the rotating shaft and is located on the side of the limit release member away from the second mounting plate;

[0042] The second stop is connected to the rotating shaft and is located on the side of the second mounting plate opposite to the limit release member.

[0043] Another aspect of this disclosure provides a cleaning device, the cleaning device comprising:

[0044] Clean the main unit;

[0045] A floor brush assembly, wherein the floor brush assembly is any one of the floor brush assemblies described above, and the floor brush assembly is installed on the cleaning host.

[0046] This disclosure further provides a cleaning system, characterized in that it includes:

[0047] Base station;

[0048] The cleaning equipment is the cleaning equipment described above, and the cleaning equipment is capable of interfacing with the base station;

[0049] The floor brush assembly includes a limit release component, and the base station includes a trigger component. When the cleaning device is connected to the base station, the trigger component contacts the limit release component and applies an unlocking force to the limit release component to switch the limit component from the first state to the second state.

[0050] In one exemplary embodiment of this disclosure, the drive is configured to drive the scraper to switch between the second working station and the self-cleaning station in response to the docking state of the cleaning device and the base station.

[0051] In one exemplary embodiment of this disclosure, one of the trigger and the limit release member has a Hall sensor and the other has a magnet;

[0052] When the cleaning equipment is connected to the base station, the magnet contacts the Hall sensor and generates a first trigger signal. The driving component responds to the first trigger signal and drives the scraper to move from the second working station to the self-cleaning station.

[0053] 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, and the driving component responds to the second trigger signal to drive the scraper to move from the self-cleaning station to the second working station.

[0054] The technical solution provided in this disclosure can achieve the following beneficial effects:

[0055] The floor brush assembly disclosed herein 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.

[0056] 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 its cleaning effect. It also ensures that the scraper can accurately move to the second working position when driven by the driver, further guaranteeing its cleaning performance. 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.

[0057] When the limiting member is in the second state, the scraper blade can switch between the second working position and the self-cleaning position. This design allows the scraper blade 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 blade 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 blade from colliding with other structural components, thus extending the lifespan of the scraper blade and other structural components, and ensuring the overall reliability of the floor brush assembly.

[0058] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0070] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0071] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0072] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0073] like Figures 1 to 7 As shown, this disclosure first provides a floor brush assembly 1. The floor brush assembly 1 can be installed in a cleaning device, which may include, but is not limited to, a robotic vacuum cleaner, a floor scrubber, a sweeping machine, etc.

[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 connected to the scraper 11 for driving 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 station to the second working station, but cannot switch from the second working station to the self-cleaning station. When the limiting member 12 is in the second state, the scraper 11 can be driven to switch from the second working station to the self-cleaning station.

[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 overall reliability of the floor brush assembly 1.

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

[0079] In one embodiment of this disclosure, such as Figures 1 to 7 As shown, 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 station to the self-cleaning station.

[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 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] In one embodiment, 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] In one embodiment, 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 utilize this movable space to make a small-amplitude movement, allowing the scraper 11 to switch from the first working position to the second working position, or vice versa, so that the floor brush assembly 1 can arbitrarily switch the scraper 11 between the first and second working positions according to cleaning needs. Specifically, when cleaning is not required using the scraper 11, it can switch to the first working position without the restriction of the limiting member 12; when cleaning is required using the scraper 11, it can also switch to the second working position without the restriction of the limiting member 12. Simultaneously, if the scraper 11 encounters an obstacle while working in the second working position, it can 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] In one embodiment of this disclosure, such as Figures 1 to 7 As shown, 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] In one embodiment of this disclosure, such as Figures 1 to 5 As shown, 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 rotate relative to the floor brush cover 14 to switch between a first working station, a second working station, and a self-cleaning station.

[0086] For example: when the scraper 11 needs to switch from the first working position to the second working position, the drive unit 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 unit 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 unit 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 is not needed for work or self-cleaning, the drive unit 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. 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] In one embodiment, the extension plate 122 can be mounted on the brush cover plate 14 and can be disposed 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 extends 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 groove 112 disengages from the limiting groove 112.

[0089] In one embodiment, when the scraper blade 11 rotates from the first working station to the second working station, 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 station to the second working station, 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] In one embodiment of this disclosure, such as Figures 1 to 7 As shown, 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] In another embodiment, 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] In one embodiment, such as Figure 2 and Figure 5As shown, 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 arrangement, 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 blade 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 blade 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 blade 11, and facilitating the operation of the limit release member 13.

[0096] In one embodiment, 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] like Figures 1 to 7As shown, 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 disclosure enables the limiting member 12 to switch arbitrarily between the first state and the second state.

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

[0099] In one embodiment, 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, thereby limiting the torsion spring and preventing positional displacement or detachment during deformation or recovery.

[0100] The connecting portion 154 can be located at one end of the main body 153, and the connecting portion 154 can be connected to the floor brush cover 14. The reset portion 155 can be located at the other end of the main body 153, and the reset portion 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] In one embodiment, such asFigure 2 and Figure 4 As shown, 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 arrangement, 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] In one embodiment, 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 disclosure does not limit this, and the elements may be selected and set according to actual needs, all of which are within the protection scope of this disclosure.

[0108] In one embodiment of this disclosure, such as Figure 1 , Figure 2 and Figure 7 As shown, 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 arrangement 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] In one embodiment, 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, this is not a limitation; 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 disclosure also provides a cleaning device. This cleaning device may include, but is not limited to, robotic vacuum cleaners, floor scrubbers, and sweeping machines. Figures 1 to 7 As shown, the cleaning equipment may include a cleaning main unit and a floor brush assembly 1. The floor brush assembly 1 may be the floor brush assembly 1 described above, 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 the previous embodiment. Therefore, in this embodiment, the specific structure and beneficial effects of the floor brush component 1 will not be described again. Please refer to the specific description in the previous embodiment. All of these are within the protection scope of this disclosure.

[0113] The cleaning equipment provided in this disclosure may include the floor brush assembly 1 described above. The floor brush assembly 1 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 avoiding any impact on 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 performance. 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, thus 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 blade 11 can switch between the second working position and the self-cleaning position. This configuration allows the scraper blade 11 to be released by the limiting member 12 when it is not working and needs self-cleaning, ensuring that the scraper blade 11 can smoothly switch to the self-cleaning position for self-cleaning. Furthermore, since the scraper blade 11 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 blade 11 from colliding with other structural components, thus extending the service life of the scraper blade 11 and other structural components, and ensuring the overall reliability of the floor brush assembly 1.

[0116] This disclosure also provides a cleaning system. The cleaning system may include a base station and cleaning equipment. The cleaning equipment may be the cleaning equipment described above, and the cleaning equipment may interface with the base station to charge or clean the cleaning equipment using the base station.

[0117] It should be noted that the specific structure and beneficial effects of the cleaning equipment have been described in detail in the previous embodiment. Therefore, the specific structure and beneficial effects of the cleaning equipment will not be described again in this embodiment. Please refer to the specific description in the previous embodiment. All of these are within the protection scope of this disclosure.

[0118] The cleaning system provided in this disclosure includes the cleaning equipment described above, such as... Figures 1 to 7 As shown, the cleaning equipment described above 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 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 system.

[0120] When the limiting member 12 is in the second state, the scraper 11 can switch between the second working station and the self-cleaning station. 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 station for self-cleaning. Furthermore, since the scraper 11 is not working at this time, it is generally not subjected to significant impact, resulting in less force when switching to the self-cleaning station. 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] In one embodiment of this disclosure, such as Figure 1 , Figure 2 and Figure 4 As shown, 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 the second working station and the self-cleaning station 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 station to the self-cleaning station; 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 station to the second working station.

[0123] In one embodiment, 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 docks 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 station to the self-cleaning station; and / or when the cleaning device separates 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 station to the second working station.

[0124] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
