Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to roller brush cylinders, roller brush mechanisms, cleaning equipment and their cleaning base stations. Background Technology

[0002] In the field of home cleaning, as living standards improve, people's cleaning needs are becoming increasingly diverse. Different cleaning scenarios, such as hard floors, carpets, and tile grout, as well as various types of dirt such as solid particles, small debris, and hair, all place different demands on cleaning equipment. To meet these diverse cleaning needs, cleaning equipment needs to be equipped with and able to flexibly replace various cleaning components to achieve efficient and precise cleaning results. Cleaning equipment includes a roller brush, which effectively removes solid particles, debris, hair, and other dirt adhering to the floor through rotating combing and sweeping motions, thus ensuring the floor's cleanliness.

[0003] The cleaning equipment in the relevant technologies is not easy to disassemble, and it is time-consuming and labor-intensive to change different types of roller brushes according to different application scenarios, which reduces cleaning efficiency. Utility Model Content

[0017] The elastic element is configured to push against the limiting body, causing the limiting body and the second housing to move away from each other. The limiting body drives the first limiting support to rotate relative to the second limiting through hole, and the first limiting protrusion moves from the recessed position to the protruding position.

[0018] In one embodiment, the sidewall of the annular groove away from the second limiting support has a plurality of first inclined surfaces and a plurality of second inclined surfaces, which are alternately connected in sequence around the first limiting through hole;

[0054] First Embodiment

[0055] like Figures 1-4 As shown, a roller brush cylinder 1 is used in a roller brush mechanism to connect with the roller brush sleeve 2 in the mechanism. It shields part of the structure of the roller brush sleeve 2 to provide protection, while ensuring that the roller brush sleeve 2 can function properly to clean the floor. The roller brush cylinder 1 includes a first housing 11, a second housing 12, and a limiting component 13.

[0056] In this embodiment, as Figures 1-4 As shown, the first housing 11 is provided with a first limiting through hole 111 for installing the limiting component 13. The first housing 11 can be fixedly connected to the roller brush assembly 2, such as by welding or riveting. This connection method ensures the stability of the connection and is suitable for scenarios requiring high connection strength and where frequent disassembly is not necessary. It ensures that the first housing 11 and the roller brush assembly 2 are tightly connected during cleaning and will not separate due to vibration or other factors, thus ensuring the smooth progress of the cleaning work. Alternatively, the first housing 11 can be detachably connected to the roller brush assembly 2, such as by snap-fit ​​connection or threaded connection. When the roller brush assembly 2 needs cleaning or replacement, the operation can be carried out conveniently and quickly, improving the convenience of use and maintenance efficiency.

[0057] In this embodiment, as Figures 1-4 As shown, the second housing 12 is connected to the first housing 11, and the two together provide shielding protection for the roller brush assembly 2. At least one of the second housing 12 and the first housing 11 is provided with an avoidance opening 14, which can expose part of the structure of the roller brush assembly 2, allowing the roller brush assembly 2 to contact the ground and perform cleaning work, thus protecting the roller brush assembly 2 without affecting its cleaning function.

[0058] The second housing 12 is provided with a second limiting through hole 121 corresponding to the first limiting through hole 111. The first limiting through hole 111 and the second limiting through hole 121 are coaxially arranged, and their inner diameters are designed according to actual needs, for example, by referring to the structural dimensions of the limiting component 13, to enhance the limiting effect. The second housing 12 is detachably connected to the main body of the cleaning equipment to facilitate flexible disassembly of the roller brush mechanism. When the roller brush mechanism malfunctions or needs to be upgraded, it can be operated quickly, reducing equipment downtime and improving efficiency.

[0059] The second housing 12 is detachably connected to the first housing 11 by a limiting component 13, which facilitates the disassembly of the roller brush assembly 2 for cleaning or replacement, ensuring the cleanliness of the roller brush assembly 2, thereby extending its service life and improving the cleaning effect.

[0060] In this embodiment, as Figures 1-4 As shown, one end of the limiting component 13 passes through the first limiting through hole 111 and the second limiting through hole 121 in sequence, and extends to the side of the second housing 12 opposite to the first housing 11. The limiting component 13 can rotate relative to the second limiting through hole 121, so that the roller brush cylinder 1 has a locked state and an unlocked state.

[0061] When the roller brush cylinder 1 is in the locked state, one end of the limiting component 13 is engaged with the second housing 12 along the axial direction of the second limiting through hole 121. For example, one end of the limiting component 13 is provided with a protruding structure, and the second housing 12 is provided with a corresponding groove structure. When the limiting component 13 rotates to a certain angle, the protruding structure is engaged in the groove structure, restricting the axial movement of the limiting component 13, thereby locking the roller brush cylinder 1 on the equipment body, ensuring the stability of the roller brush mechanism during operation, and preventing the roller brush cylinder 1 from separating from the equipment body due to shaking or vibration, which would affect the normal operation of the cleaning work.

[0062] When the roller brush cylinder 1 is in the unlocked state, the limiting component 13 releases its axial limiting engagement with the second housing 12 along the second limiting through hole 121. For example, by rotating the limiting component 13 in the reverse direction, the protruding structure disengages from the groove structure. At this time, the limiting component 13 can move axially, allowing the roller brush cylinder 1 to be removed from the equipment body, facilitating the replacement, maintenance, and other operations of the roller brush cylinder 1 or the roller brush assembly 2.

[0063] In this embodiment, the roller brush cylinder 1 allows for convenient disassembly of the first housing 11 and the second housing 12 via the limiting component 13. This facilitates the cleaning and replacement of the roller brush assembly 2. The detachable connection allows users to easily remove the roller brush assembly 2 from the roller brush cylinder 1 for cleaning, maintaining its cleanliness and improving cleaning effectiveness. The limiting component 13 rotates relative to the second limiting through hole 121 to lock and unlock the roller brush cylinder 1, providing convenience and speed. When the roller brush assembly 2 is severely worn or needs to adapt to different cleaning scenarios, it can be quickly replaced, improving the adaptability and flexibility of the equipment.

[0064] Second Embodiment

[0065] like Figures 1-5 As shown, the second embodiment of this application also provides a roller brush cylinder 1. The roller brush cylinder 1 provided in the first embodiment is the same or similar in overall structure and application scenario. It is also used in a roller brush mechanism to connect with the roller brush sleeve 2 in the roller brush mechanism, to shield part of the structure of the roller brush sleeve 2 for protection, and to ensure that the roller brush sleeve 2 can perform its function of cleaning the floor normally. The roller brush cylinder 1 includes a first housing 11, a second housing 12, and a limiting component 13. The difference is that the limiting component 13 includes a limiting body 131, a first limiting support 132, and a second limiting support 133.

[0066] The first limiting support 132 and the second limiting support 133 are respectively disposed on both sides of the limiting body 131 along the axial direction of the limiting assembly 13, and are connected to the limiting body 131. The second limiting support 133 is larger than the inner diameter of the first limiting through hole 111, thus restricting the second limiting support 133 to the side of the first housing 11 opposite to the second housing 12, thereby preventing the limiting assembly 13 from detaching. The first limiting support 132 is smaller than the inner diameter of the first limiting through hole 111, allowing the first limiting support 132 to pass sequentially through the first limiting through hole 111 and the second limiting through hole 121, and extend to the side of the second housing 12 opposite to the first housing 11.

[0067] When the limiting component 13 is rotated, it drives the first limiting support 132 to rotate relative to the second limiting through hole 121, thereby allowing the limiting component 13 to switch between the unlocked state and the locked state to meet the user's needs.

[0068] When the brush cylinder 1 is in the unlocked state, the first limiting support 132 is aligned with the second limiting through hole 121, that is, the projection of the first limiting support 132 along the axial direction of the limiting component 13 coincides with the second limiting through hole 121. The axial projection direction of the limiting component 13 is consistent with the separation or assembly direction between the brush sleeve 2 and the brush cylinder 1, or the axial projection direction of the limiting component 13 is perpendicular to the plane where the brush cylinder 1 is located. At this time, the first limiting support 132 can smoothly pass through the second limiting through hole 121, allowing the user to remove the brush cylinder 1 from the equipment body for convenient replacement, maintenance, and other operations of the brush cylinder 1 or the brush sleeve 2.

[0069] When the roller brush cylinder 1 is in the locked state, that is, the projection of the first limiting support 132 along the axial direction of the limiting component 13 only partially overlaps with the second limiting through hole 121, and the first limiting support 132 and the second limiting through hole 121 are misaligned. At this time, the first limiting support 132 is restricted to one side of the second housing 12, preventing the limiting component 13 from moving axially, thereby locking the roller brush cylinder 1 on the equipment body, ensuring the stability of the roller brush mechanism during operation, and preventing the roller brush cylinder 1 from separating from the equipment body due to shaking or vibration, which would affect the normal progress of cleaning work.

[0070] In this embodiment, the roller brush cylinder 1, through the structural design of the limiting component 13, achieves a more stable and flexible detachable connection between the first housing 11 and the second housing 12. This facilitates the cleaning and replacement of the roller brush assembly 2, allowing users to easily remove the roller brush assembly 2 from the roller brush cylinder 1 for cleaning, maintaining its cleanliness and thus improving cleaning effectiveness. Simultaneously, the limiting component 13 allows for easy and quick locking and unlocking of the roller brush cylinder 1 through a simple rotation operation. When the roller brush assembly 2 is severely worn or needs to adapt to different cleaning scenarios, it can be quickly replaced, improving the adaptability and flexibility of the equipment and providing a better user experience.

[0071] Third Embodiment

[0072] like Figures 1-5 As shown, the third embodiment of this application also provides a roller brush cylinder 1. The roller brush cylinder 1 provided in the second embodiment is the same or similar in overall structure and application scenario. It is also used in a roller brush mechanism to connect with the roller brush sleeve 2 in the roller brush mechanism, to shield part of the structure of the roller brush sleeve 2 for protection, and to ensure that the roller brush sleeve 2 can perform its function of cleaning the floor normally. The roller brush cylinder 1 includes a first housing 11, a second housing 12, and a limiting component 13. The limiting component 13 includes a limiting body 131, a first limiting support 132, and a second limiting support 133. The difference is that the limiting component 13 includes an elastic element 134, and the second housing 12 is provided with a first receiving groove 122.

[0073] The first receiving groove 122 communicates with the first limiting through hole 111 and the second limiting through hole 121, providing the necessary space channel for the installation and movement of the limiting component 13. The elastic element 134 is disposed within the first receiving groove 122, and its shape and size are designed according to the dimensions of the elastic element 134 to ensure that the elastic element 134 can be stably disposed within the first receiving groove 122.

[0074] For example, the elastic element 134 is a cylindrical spring, which has good elasticity and stability, and can undergo elastic deformation when subjected to force and return to its original shape after the external force is removed. The first receiving groove 122 is a matching cylindrical groove, the inner diameter of which is larger than the outer diameter of the elastic element 134, and the depth is sufficient to accommodate the length change of the elastic element 134 in the compressed or extended state, so as to ensure that the elastic element 134 can be stably set in the first receiving groove 122 and will not shift or fall off during operation.

[0075] The elastic element 134 is configured to push the limiting body 131 to move axially along the limiting assembly 13, causing the second limiting support 133 to move away from the first housing 11. The limiting assembly 13 has a certain elastic buffering effect during installation and use, and can better adapt to different working scenarios and stress conditions.

[0076] Simultaneously, the overall stability of the limiting component 13 can be achieved, ensuring its secure placement on the first housing 11 and the second housing 12. For example, the limiting body 131 includes a first rod 1311 and a second rod 1312, which are connected. The first rod 1311 is connected to the first limiting support 132, and the second rod 1312 is connected to the second limiting support 133, enabling the limiting body 131 to engage with the first housing 11 and the second housing 12 through the first limiting support 132 and the second limiting support 133.

[0077] The outer diameter of the first rod 1311 is smaller than that of the second rod 1312. An elastic element 134 is fitted onto the first rod 1311, with one end abutting the axial surface of the second rod 1312 and the other end abutting the bottom surface of the first receiving groove 122, thus improving the overall stability of the limiting assembly 13. When the roller brush cylinder 1 is subjected to external force during operation, the elastic element 134 can support and limit the limiting body 131 through its elastic force, preventing axial movement and shaking of the limiting body 131, thereby ensuring the stability of the connection between the first housing 11 and the second housing 12.

[0078] In this embodiment, the roller brush cylinder 1 optimizes the structure of the limiting component 13 by setting the elastic element 134 and the first receiving groove 122, thereby improving the stability and adaptability of the roller brush cylinder 1 during operation and better meeting the usage requirements of the roller brush mechanism in different working scenarios.

[0079] Fourth embodiment

[0080] like Figures 1-6 As shown, the fourth embodiment of this application also provides a roller brush cylinder 1. The roller brush cylinder 1 provided in the third embodiment is the same or similar in overall structure and application scenario. It is also used in the roller brush mechanism to connect with the roller brush sleeve 2 in the roller brush mechanism, to shield part of the structure of the roller brush sleeve 2 to form protection, and at the same time to ensure that the roller brush sleeve 2 can perform its function of cleaning the ground normally. The roller brush cylinder 1 includes a first housing 11, a second housing 12 and a limiting component 13. The limiting component 13 includes a limiting body 131, a first limiting support 132, a second limiting support 133 and an elastic member 134. The difference is that the limiting component 13 also includes a first limiting protrusion 135, and the inner wall of the first limiting through hole 111 is provided with an annular groove 1111 for accommodating the first limiting protrusion 135.

[0081] Along the axial direction of the limiting component 13, the sidewall of the annular groove 1111 away from the second limiting support 133 has a recessed position 1112 and a raised position 1113. The distribution of the recessed position 1112 and the raised position 1113 on the sidewall of the annular groove 1111 can be determined according to actual design requirements. For example, the recessed position 1112 and the raised position 1113 can be evenly spaced to ensure the stability and reliability of the limiting component 13 during movement. The recessed position 1112 is recessed inward to a certain depth relative to other parts of the sidewall of the annular groove 1111, while the raised position 1113 protrudes outward to a certain height, forming a significant height difference between the two, thereby realizing the unlocking and locking functions of the limiting component 13.

[0082] For example, an external force along the axial direction of the second limiting through hole 121 can be applied to the limiting component 13 manually or by other mechanical means, i.e., pressing the second limiting support 133, causing the limiting component 13 to move along the axial direction of the second limiting through hole 121. As the limiting component 13 moves, due to the mutual resistance between the first limiting protrusion 135 and the annular groove 1111, and influenced by the height difference between the recessed position 1112 and the protruding position 1113, during the movement, this height difference will force the limiting body 131 to drive the first limiting support 132 to rotate relative to the second limiting through hole 121. Specifically, the first limiting protrusion 135 slides in the annular groove 1111. When it encounters the height difference between the protrusion position 1113 and the recessed position 1112, the limiting body 131 will rotate, thereby driving the first limiting support 132 to rotate relative to the second limiting through hole 121, and finally causing the first limiting protrusion 135 to move from the protrusion position 1113 to the recessed position 1112.

[0083] When the external force applied to the limiting component 13 is removed, the elastic element 134 is set to push against the limiting body 131, causing the limiting body 131 to move away from the second housing 12. The limiting body 131 then drives the first limiting support 132 to rotate relative to the second limiting through hole 121. As the first limiting support 132 rotates, the first limiting protrusion 135 moves within the annular groove 1111, from the recessed position 1112 to the protruding position 1113.

[0084] At this time, if the first limiting support 132 is aligned with the second limiting through hole 121, it indicates that the roller brush cylinder 1 is in the unlocked state and can be disassembled. If the first limiting support 132 is misaligned with the second limiting through hole 121, it indicates that the roller brush cylinder 1 is in the locked state.

[0085] To switch between the unlocked and locked states, press the limit component 13 again to rotate it. In practical applications, when the roller brush cylinder 1 needs cleaning or maintenance after a period of use, the operator can manually or mechanically press the second limit support 133 to unlock the roller brush cylinder 1 according to the above unlocking procedure. Then, the roller brush cylinder 1 can be easily removed from the roller brush mechanism for cleaning or maintenance. After cleaning or maintenance, reinstall the roller brush cylinder 1 into the roller brush mechanism, press the limit component 13 again to rotate the first limit support 132 until it is misaligned with the second limit through hole 121. At this time, the roller brush cylinder 1 is in the locked state, ensuring that the roller brush cylinder 1 works stably in the roller brush mechanism and performs its normal function of cleaning the floor.

[0086] In this embodiment, the limiting component 13, when moving axially, is restricted by the recessed position 1112 and the protruding position 1113 provided on the side wall of the annular groove 1111. This causes the limiting component 13 to also move circumferentially along the axial direction of the second limiting through hole 121. That is, the limiting body 131 rotates relative to the second limiting through hole 121, completing the movement of the first limiting protrusion 135 between the recessed position 1112 and the protruding position 1113, thus realizing the switching between the unlocked state and the locked state. The axis of the limiting component 13 is coaxially arranged with the axis of the second limiting through hole 121, and the circumferential movement of the limiting component 13 is circumferential around the axis of the limiting component 13 or the axis of the second limiting through hole 121.

[0087] By utilizing the interaction between the first limiting protrusion 135 and the annular groove 1111, as well as the elastic force of the elastic element 134, the roller brush cylinder 1 can be conveniently switched between the unlocked and locked states, thereby improving the ease of use and reliability of the roller brush cylinder 1.

[0088] In this embodiment, as Figures 1-6 As shown, the sidewall of the annular groove 1111 away from the first limiting support 132 has multiple first inclined surfaces 1114 and multiple second inclined surfaces 1115. The multiple first inclined surfaces 1114 and multiple second inclined surfaces 1115 are connected alternately around the first limiting through hole 111 to form an orderly arrangement structure.

[0089] Between adjacent first inclined surfaces 1114 and second inclined surfaces 1115, their inclination trends are set in opposite directions, so that the connection position between the first inclined surface 1114 and the second inclined surface 1115 alternately forms a raised position 1113 and a recessed position 1112. This alternating raised and recessed structure provides a specific track and point of action for the movement of the limiting component 13.

[0090] The limiting component 13 is provided with a first limiting protrusion 135. When the limiting component 13 switches between the unlocked state and the locked state, the first limiting protrusion 135 interferes with the first inclined surface 1114 and the second inclined surface 1115 of the side wall of the annular groove 1111.

[0091] Since the position of the annular groove 1111 on the second housing 12 is fixed, under the interference, the first limiting protrusion 135 is forced to move along the first inclined plane 1114 or the second inclined plane 1115. As the first limiting protrusion 135 moves, it will exert a force on the limiting body 131, thereby causing the limiting body 131 to rotate. This rotation is the action to realize the switching between unlocking and locking functions.

[0092] To more precisely control the rotation angle of the limiting component 13, this embodiment optimizes the distribution of the protruding positions 1113 and the recessed positions 1112. For example, the circumferential distance between two adjacent protruding positions 1113 is set to 1 / n turns of the circumference of the first limiting through hole 111. Here, n can be 4, meaning that each press of the limiting component 13 rotates it 1 / 4 turn. Similarly, the circumferential distance between two adjacent recessed positions 1112 is 1 / n turns of the circumference of the first limiting through hole 111. Here, n can be 4.

[0093] In actual operation, when the roller brush cylinder needs to be unlocked, an external force is applied to the limiting component 13. At this time, the first limiting protrusion 135 moves along the inclined surface within the annular groove 1111. Due to the alternating setting of the protrusion position 1113 and the recessed position 1112, as well as the specific circumferential distance design, the limiting body 131 will rotate at a predetermined angle (e.g., 1 / 8 turn). When the external force is removed, under the action of the elastic element 134, the limiting body 131 will continue to rotate at a predetermined angle (e.g., 1 / 8 turn). At this time, the limiting body 131 rotates to a certain position (e.g., 1 / 4 turn), thereby releasing the axial limiting constraint relationship between the first limiting support 132 and the second limiting through hole 121, and the roller brush cylinder is in the unlocked state, allowing for convenient disassembly.

[0094] After cleaning and maintenance are completed, the roller brush cylinder needs to be reinstalled and locked. The second housing 12 is then aligned with the first housing 11. Next, press the limiting component 13; the limiting body 131 will rotate at a predetermined angle (e.g., 1 / 8 turn). When the external force is removed, the elastic element 134 will cause the limiting body 131 to continue rotating at the predetermined angle (e.g., 1 / 8 turn). At this point, the limiting body 131 rotates to a certain position (e.g., 1 / 4 turn) until the first limiting support 132 and the second limiting through hole 121 re-establish a stable axial limiting constraint relationship. The roller brush cylinder 1 is then locked, ensuring stable operation and proper floor cleaning function during subsequent use.

[0095] In this embodiment, by setting alternating first inclined surfaces 1114 and second inclined surfaces 1115 on the sidewall of the annular groove 1111, alternating protruding positions 1113 and recessed positions 1112 are formed, and the circumferential distance between adjacent protruding positions 1113 and recessed positions 1112 is reasonably designed, so that the limiting component 13 can be accurately and conveniently switched between the unlocked state and the locked state, effectively improving the performance of the roller brush cylinder 1.

[0096] Fifth Embodiment

[0097] like Figures 1-8 As shown, this embodiment provides a roller brush mechanism, including a roller brush cylinder 1 and a roller brush sleeve 2 as described in any of the first to fourth embodiments above. The roller brush sleeve 2 is connected to the first housing 11 of the roller brush cylinder 1. The first housing 11 and the second housing 12 are detachably connected via a limiting component 13, greatly facilitating the operation of the roller brush cylinder 1 when cleaning, maintenance, or replacement is required, and improving the ease of equipment maintenance.

[0098] In this embodiment, as Figures 1-8 As shown, the roller brush assembly 2 includes a roller brush component 21 and a first connecting part 22. The roller brush component 21 is used to contact the ground to remove dirt. A first connecting part 22 is provided at each end along the axial direction of the roller brush component 21. The roller brush component 21 is rotatably connected to the first housing 11 through the first connecting parts 22. The roller brush component 21 can rotate around its own axis, achieving comprehensive cleaning of the ground while improving the smoothness of rotation and reducing vibration and noise during operation.

[0099] To improve the reliability of the connection, there are radial and axial limiting fits in the connection between the first connecting part 22 and the first housing 11.

[0100] For example, in terms of radial limiting, the first connecting part 22 is provided with a second limiting protrusion 221, the first housing 11 is provided with a second receiving groove 112, the second receiving groove 112 is provided with a third limiting protrusion 1121, the third limiting protrusion 1121 and the second limiting protrusion 221 mutually limit each other in the radial direction of the limiting component 13, so as to prevent the first connecting part 22 from being displaced radially when the roller brush assembly 21 rotates, and to ensure the stable operation of the roller brush assembly 21.

[0101] To further enhance the limiting effect, at least one of the second limiting protrusion 221 and the third limiting protrusion 1121 is annular. When the first connecting part 22 rotates with the roller brush assembly 21, the annular limiting protrusion can provide a continuous and stable limiting effect, preventing the first connecting part 22 from becoming loose from the first housing 11 due to rotation, thus improving structural reliability.

[0102] For example, regarding axial limiting, the first housing 11 is provided with accommodating spaces 113 on both sides along the axial direction of the roller brush mechanism. The accommodating spaces 113 are used to accommodate the first connecting part 22. The first connecting part 22 is provided with a connecting flange 222, which partially overlaps with the accommodating space 113 along the axial direction of the roller brush mechanism, forming a mutual constraint relationship. This prevents the first connecting part 22 from moving axially, prevents axial movement of the roller brush assembly 21 during operation, and ensures the stability and consistency of the cleaning effect.

[0103] The second limiting protrusion 221 can be provided on the connecting flange 222. In addition to radial limiting, it can further restrict the first connecting part 22 from moving radially, forming multi-directional limiting protection to ensure that the first connecting part 22 is stably fixed on the first housing 11 in all directions.

[0104] In this embodiment, as Figures 1-8 As shown, the roller brush assembly 21 includes a roller brush 211, a shaft 212, and a drive unit 213. The roller brush 211 is sleeved on the shaft 212, and the shaft 212 is connected to the first connecting part 22. For example, the shaft 212 is provided with a first shaft hole 2121, and the first connecting part 22 includes a first connecting shaft 223. The first connecting shaft 223 is inserted into the first shaft hole 2121 and connected by a bearing assembly. This not only ensures stable transmission between the shaft 212 and the first connecting part 22, but also effectively reduces friction, lowers energy loss, and extends the service life of the component.

[0105] Meanwhile, the first connecting part 22 also includes a second connecting shaft 225, which has a second shaft hole 2251 into which the first connecting shaft 223 is inserted. This double-insertion connection structure further enhances the connection strength and stability between the various parts of the roller brush assembly 21, ensuring that there will be no loosening or detachment during high-speed operation, thus guaranteeing the continuity and reliability of the cleaning work.

[0106] It should be noted that the number of roller brushes 211 and the number of shafts 212 can be flexibly set according to actual usage needs. For example, in simple cleaning scenarios, one roller brush 211 and one shaft 212 can be set up, with the roller brush 211 fitted onto the shaft 212, which can meet basic cleaning requirements. This setup is simple in structure and low in cost, suitable for small areas or places where cleaning efficiency requirements are not high. When higher cleaning efficiency is required or when dealing with complex cleaning environments, two roller brushes 211 and two shafts 212 can be set up, with each roller brush 211 and shaft 212 installed in a one-to-one correspondence. In this case, the movement of the shafts 212 has two options: one is separate movement, where each shaft 212 is independently controlled and can be adjusted according to the cleaning needs of different areas to achieve precise cleaning of complex floors; the other is to use a coupling to connect the two shafts 212 together to achieve synchronous movement. This synchronized motion ensures that the two rollers 211 rotate at the same speed and direction, forming a larger cleaning area and improving cleaning efficiency, making it especially suitable for cleaning large areas of flat ground.

[0107] The drive unit 213 includes a drive body 2131 and a second connecting part 2132. The drive body 2131 is connected to the second connecting part 2132, and the second connecting part 2132 is detachably connected to the first connecting part 22, which makes the installation, disassembly and maintenance of the roller brush assembly 21 more convenient and improves the maintainability of the equipment.

[0108] The drive unit 2131 is, for example, a drive motor. The number of drive motors can be adjusted according to the configuration of the shafts 212 or the driving requirements. For example, when there are two shafts 212 that need to move separately, each can be connected to a drive motor to achieve independent driving of the two shafts 212. This allows for precise control based on the working state of different roller brushes 211, meeting diverse cleaning needs.

[0109] The driving body 2131 is configured to drive the second connecting part 2132 to rotate relative to the first connecting part 22, thereby enabling the second connecting part 2132 to be assembled or separated from the first connecting part 22. For example, the second connecting part 2132 is provided with a connecting screw hole 21321, and the first connecting part 22 is provided with a connecting screw 224. The connecting screw 224 is threadedly connected to the connecting screw hole 21321, which has the advantages of firm connection and convenient disassembly, and can ensure that there will be no loosening during the driving process.

[0110] In practical operation, the connection and disassembly can be automated using a drive motor. For example, when the drive motor rotates forward, its drive shaft drives the second connecting part 2132 to rotate, causing the connecting screw hole 21321 to gradually screw onto the connecting screw 224, achieving a tight assembly between the second connecting part 2132 and the first connecting part 22. When the drive motor rotates in reverse, its drive shaft drives the second connecting part 2132 to rotate in the opposite direction, causing the connecting screw hole 21321 to disengage from the connecting screw 224, thus separating the second connecting part 2132 from the first connecting part 22. In the assembled state, when the drive shaft of the drive motor rotates, it drives the second connecting part 2132 to rotate. The second connecting part 2132 transmits driving force to the first connecting part 22, causing it to rotate synchronously. The first connecting part 22, through its shaft 212, drives the roller brush 211 to rotate, thereby cleaning the floor.

[0111] To further optimize the performance of the drive unit 213, a spring 2133 is fitted onto the drive shaft of the drive motor, with both ends of the spring 2133 abutting against the second connecting part 2132 and the housing of the drive motor, respectively. On one hand, the spring 2133 provides a certain preload, making the connection between the second connecting part 2132 and the first connecting part 22 tighter, reducing the gap at the threaded connection, and improving the stability and reliability of the transmission. On the other hand, when the drive motor rotates the second connecting part 2132 for assembly or disassembly operations, the spring acts as a buffer, reducing the impact force during rotation, protecting the components from damage, and extending the service life of the equipment.

[0112] In this embodiment, the roller brush assembly 21, through a reasonable structural design, achieves a stable connection between the roller brush 211 and the shaft 212, flexible quantity settings, and automated control and optimization of the drive unit 213, providing an efficient and reliable solution for floor cleaning.

[0113] Sixth Embodiment

[0114] like Figures 1-8 As shown, this embodiment provides a cleaning device, including a device body (not shown in the figure) and a roller brush mechanism as described in the fifth embodiment above. The device body is connected to the second housing 12 of the roller brush mechanism. The second housing 12 is provided with a connecting rod 123 for connection to the device body.

[0115] The main body of the equipment serves as the supporting component of the cleaning equipment, undertaking the important tasks of providing power and control for the entire cleaning equipment and accommodating other necessary components. The connection between the main body of the equipment and the second housing 12 of the roller brush mechanism can take various forms, such as bolt connection, snap-fit ​​connection, or welding, depending on the actual situation.

[0116] In this cleaning equipment, the roller brush mechanism, connected to the main body of the equipment, achieves efficient cleaning of the floor under the power and control provided by the main body. The power of the drive unit 2131 is transmitted to the shaft 212 through the first connecting part 22, and the shaft 212 drives the roller brush 211 sleeved on it to rotate. The bristles or cleaning structure on the surface of the roller brush 211 come into contact with the ground, and removes dust, stains and other impurities from the ground through rotational friction and tapping.

[0117] Seventh Embodiment

[0118] In related technologies, most roller brushes lack effective automated disassembly and assembly structures in their design. This means that in actual use, when different types of roller brushes need to be replaced for different scenarios, manual disassembly and installation are often required. Manual operation is not only time-consuming and labor-intensive, reducing cleaning efficiency, but also prone to damage to the roller brush or cleaning equipment due to improper operation during frequent brush changes. More importantly, these roller brushes lacking automated disassembly and assembly structures cannot be well adapted to cleaning equipment and cleaning stations with automated functions. This makes it difficult to truly achieve the goal of automatically using different roller brushes for different scenarios, failing to fully utilize the automation advantages of cleaning equipment and failing to meet the urgent needs of modern home environments for efficient and convenient cleaning.

[0119] like Figures 1-8 As shown, this embodiment provides a clean base station, including a base station body (not shown in the figure) and a drive mechanism (not shown in the figure), the drive mechanism being disposed on the base station body. The drive mechanism may be, for example, a drive cylinder or other device capable of providing linear thrust, such as an electric push rod.

[0120] The base station body is used to house the cleaning equipment as described in the sixth embodiment. The cleaning equipment includes a roller brush mechanism. The drive mechanism can push the limiting component 13 in the roller brush mechanism, causing the limiting component 13 to rotate relative to the second limiting through hole 121 in the roller brush mechanism. This realizes the automated disassembly and installation / replacement of the roller brush mechanism, effectively improving the targeting and efficiency of cleaning.

[0121] In the cleaning base station, the cleaning equipment and the drive mechanism work together. When it is necessary to replace the roller brush cylinder 1 according to the ground material and the characteristics of the dirt, the control system of the cleaning base station first analyzes and judges the current cleaning scenario to determine the type of roller brush that needs to be replaced. Then, the control system sends a command to the drive mechanism, and the drive mechanism starts to work. Taking the drive cylinder as an example, the piston rod of the drive cylinder extends and pushes against the limiting component 13. After being pushed, the limiting component 13 rotates relative to the second limiting through hole 121.

[0122] In the initial state, the limiting component 13 is in the locked position, firmly fixing the roller brush cylinder 1 to the cleaning equipment and ensuring that the roller brush cylinder 1 will not loosen or fall off during the cleaning process. When it is necessary to remove the roller brush cylinder 1, the cleaning equipment returns to the cleaning base station, and the drive mechanism pushes the limiting component 13 to move axially, causing the limiting component 13 to switch from the locked state to the unlocked state. At this time, the roller brush cylinder 1 is no longer restricted by the limiting component 13 and can be easily removed from the cleaning equipment.

[0123] When installing a new roller brush cylinder 1, the new roller brush cylinder 1 is placed in the corresponding position on the cleaning equipment. Then, the drive mechanism pushes the limiting component 13 to move axially, causing the limiting component 13 to switch from the unlocked state to the locked state, thus firmly fixing the new roller brush cylinder 1 to the cleaning equipment. This automated method enables the quick disassembly and replacement of the roller brush cylinder 1.

[0124] The automation capabilities of the cleaning base station enable the cleaning equipment to quickly switch between appropriate roller brush sets 2 according to different cleaning scenarios. For example, when cleaning wooden floors, it can automatically switch to a soft-bristled roller brush to avoid scratching the floor surface; when cleaning carpets, it can switch to a hard-bristled roller brush with stronger cleaning power to penetrate deep into the carpet fibers to remove dust and stains; when cleaning oil stains on kitchen floors, it can switch to a roller brush with special cleaning agents or a rubber roller brush with stain removal capabilities, etc.

[0125] This automatic roller brush replacement system, adapting to different scenarios, significantly improves the targeted nature and efficiency of cleaning. The elimination of manual roller brush replacement saves time and labor costs, while also preventing equipment damage caused by improper human operation. Furthermore, the cleaning base station is well-integrated with automated cleaning equipment, fully leveraging the automation advantages of such equipment to better meet the urgent needs of modern homes for efficient and convenient cleaning.

[0126] In addition, the base station body can also be equipped with cleaning and charging functions to facilitate the cleaning of the roller brush mechanism and to charge the cleaning equipment, depending on actual needs.

[0127] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0128] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
