Technical Field

[0002] This application relates to a roller brush assembly for cleaning equipment and a cleaning equipment. Specifically, this document discloses a roller brush assembly including a roller brush having a free end. Background Technology

[0003] Cleaning equipment, such as cleaning robots, helps users clean surfaces in various environments. Most cleaning equipment is equipped with roller brush assemblies and vacuum systems to absorb debris and dust from surfaces and guide them to appropriate collectors within the cleaning device. Existing roller brushes are fixed inside the cleaning device at both ends, but this structure is complex and inefficient at collecting waste such as hair. In contrast, some cleaning equipment uses cantilevered roller brushes, which connect to the cleaning device at only one end, solving the problems of structural complexity and efficiency. As a trade-off, these cantilevered roller brushes are less stable during device operation than traditional roller brushes because they are only connected to the cleaning device through a single mounting end. Therefore, improvements to cantilevered roller brushes are worth considering. Summary of the Invention

[0031] Turning now to embodiments of this disclosure, a novel method is provided to improve the stability of a cantilever roller brush by connecting it to a cleaning device via a mounting bracket, rather than a direct connection between the cantilever roller brush and the cleaning device. The cantilever roller brush is connected to the mounting bracket via at least one bearing, such that the mounting bracket is fixed to the cleaning device while the cantilever roller brush can rotate during cleaning. As shown in this disclosure, the stability of the cantilever roller brush can be significantly improved by customizing the structure of the mounting bracket.

[0032] Additional novel features will be set forth in the following description, and in part will become apparent to those skilled in the art upon reading the following description and figures or by learning through implementing the examples provided herein. The novel features of this disclosure can be realized and obtained by practice or by using various aspects of the methods, means, and combinations set forth in the following detailed examples.

[0033] This disclosure provides a roller brush assembly and a cleaning device, which may be, for example, a handheld vacuum cleaner, a floor scrubber, a cleaning robot, a mopping robot, or a robot capable of performing at least one of mopping, cleaning, and washing operations. In this embodiment, reference is made to... Figure 1A and Figure 1BTaking cleaning equipment 100 as an example, the structure of the cantilever roller brush assembly provided in this disclosure will be described. It should be noted that the cantilever roller brush assembly can be applied to any suitable vacuum cleaning equipment with roller brush.

[0034] Cleaning device 100 removes debris or dust from a surface by agitating, lifting, and collecting it by applying negative pressure above the surface. The debris or dust described herein is not limited to solid matter but may also include hair, thread, liquid, etc. In some embodiments, cleaning device 100 includes a chassis 102 and a body 101 connected to the chassis 102. The body 101 is supported by a drive system that can manipulate the cleaning device 100 to move across a floor surface according to commands. Commands may be entered directly by a user on the cleaning device 100 or via a remote control. Commands may also be executed by the device itself via pre-installed or downloaded software instructions upon triggering an event (e.g., detecting an environmental change). The drive system may include a left drive wheel 103-1 and a right drive wheel 103-2 each having a respective drive motor, and casters 104 configured to further support the cleaning device 100. Cleaning device 100 may also include a sensor system with one or more sensors. These sensors can work independently or in conjunction to detect the environment surrounding the cleaning device 100, enabling the cleaning device 100 to make intelligent decisions about what action to take in that environment. The sensor system may include one or more of the following: obstacle detection and avoidance sensors, communication sensors, navigation sensors, etc. The cleaning device 100 may include a navigation system configured to operate the cleaning device 100. In one example, when the cleaning device 100 detects an obstacle such as a wall or furniture using the obstacle detection and avoidance sensors, the sensors send a signal to a processor executing software instructions, triggering the navigation system to bypass the obstacle.

[0035] The cleaning device 100 may also include a cleaning system, such as a dry cleaning system. The dry cleaning system includes at least one roller brush assembly and at least one side brush assembly. The roller brush assembly is typically mounted in the suction chamber of the cleaning device 100 (e.g., Figures 2A to 3The suction chamber 10 shown is located within the cleaning device 100. The suction chamber has an opening and an outlet through which dust-laden air is drawn from outside the cleaning device 100, passes through the suction chamber, and enters other components of the cleaning device 100. The dust-laden air is then conveyed to a collector (not shown) of the cleaning device 100 to separate dust, debris, or grime from the air before it is expelled from the cleaning device 100. The opening is in the form of an aperture, typically an elongated rectangular aperture defined by a base plate located at the bottom of the body 101 of the cleaning device 100. A roller brush protrudes from the aperture and can contact the surface to be cleaned through the opening. In some embodiments, the outlet is located between the two mounting ends of the roller brush, equidistant from each mounting end. In some other embodiments, when the roller brush is a cantilevered roller brush, the outlet is located off-center between the two mounting ends of the roller brush.

[0036] According to this disclosure, the roller brush of each roller brush assembly can be driven by an electric motor powered by the cleaning device 100. When the cleaning device 100 moves to the surface to be cleaned, the electric motor can rotate the roller brush at a predetermined speed. Therefore, while moving, the cleaning device 100 can sweep debris or dust scattered on the surface into its collector. When the surface to be cleaned has a high coefficient of friction, the cleaning process may consume a significant amount of energy. For example, when cleaning a carpet, the carpet fibers are simultaneously agitated, thus slowing down the rotation of the roller brush and the movement of the cleaning device 100.

[0037] During the cleaning process, in some embodiments, the bristles of the roller brush move from the front edge to the rear edge of the opening, sweeping debris or dust backward across the opening into the suction chamber. The vacuum suction function of the cleaning device 100 causes air to flow under the base plate and around the roller brush, thereby lifting debris or dust from the surface and then conveying it from the suction chamber to the collector through the outlet. As debris or dust passes through the outlet, long pieces of debris (such as hair, thread, etc.) may become entangled on the roller brush or accumulate at or near the outlet, especially at the mounting end of the roller brush. This is because the airflow through the suction chamber exerts relatively little force on these long pieces of debris, making it unlikely they will be blown or dragged into the collector even if the roller brush rotates at a speed capable of sucking in solid debris. Entangled hair or thread can increase the torque on the roller brush, slow its rotation speed, and accumulated hair or thread may partially block the air outlet or be expelled from the suction chamber by turbulent airflow, resulting in reduced cleaning efficiency and increased power consumption of the cleaning device 100.

[0038] The cantilever roller brush effectively solves the aforementioned problems by reducing the number of mounting ends from two to one and moving the outlet to one end of the suction chamber opposite the mounting end. Reducing the number of mounting ends by half reduces the amount of debris entangled on the roller brush. Since the outlet is located at one end of the suction chamber, an air passage is formed between the mounting end and the outlet, with a length similar to the length of the roller brush. This makes it easy to guide debris and dust from the suction chamber to the outlet. However, because the cantilever roller brush has only one mounting end, its stability is relatively poor.

[0039] This disclosure provides a different and novel structure for connecting a cantilever roller brush to a cleaning device 100, retaining its advantages while eliminating its disadvantages. In some embodiments, the cantilever roller brush is connected to the cleaning device 100 via a mounting bracket, rather than a conventional direct connection between the cantilever roller brush and the cleaning device. The mounting bracket is connected to the suction chamber by at least one pair of action and reaction forces applied to the mounting bracket and the suction chamber, such that the mounting bracket is fixed to the cleaning device while the cantilever roller brush can rotate during cleaning. This customized mounting bracket structure can significantly improve the stability of the cantilever roller brush. Furthermore, the cantilever roller brush according to this disclosure can be easily removed from the suction chamber in a direction toward the opening of the suction chamber, making its replacement and inspection easier than existing products. Details of the mounting bracket and its connection to the suction chamber of the cleaning device 100 will be described in detail below.

[0040] In some embodiments, please refer to Figure 1B , Figure 2A and Figure 7 The cleaning device 100 includes a suction chamber 10 disposed at the bottom of the main body 101 and a roller brush assembly 20 installed within the suction chamber 10. For example... Figures 2A to 3 As shown, the suction chamber 10 and the roller brush assembly 20 are collectively referred to as the cleaning assembly 200. In some embodiments, at least a portion of the cleaning assembly 200 can be removed from the bottom of the cleaning device 100. For example, as Figure 3 As shown, the roller brush assembly 20 can be removed from the cleaning assembly 200, thereby removing the roller brush assembly 20 from the cleaning device 100. In another embodiment, the cover can be removed from the rest of the suction chamber 10 (e.g., Figure 2B (Cover 13). This makes it easy to replace or inspect the parts of the cleaning assembly 200. The suction chamber 10 is provided with an opening 12 through which debris and dust can be picked up and guided through an outlet 14 to the collector of the cleaning device 100. At least a portion of the roller brush assembly 20 is exposed through the opening 12 and is adjacent to or in contact with the surface to collect debris and dust from the surface.

[0041] In some embodiments, such as Figure 2B and Figure 3As shown, the suction chamber 10 includes a base 11 connected to the cleaning device 100 and a cover 13 connected to the base 11. The cover 13 has an opening 12 that is close to the surface to be cleaned during cleaning, so that debris and dust can be swept into the suction chamber 10 through the opening 12. The shape of the opening 12 can be configured to match the portion of the roller brush assembly 20 facing the surface to be cleaned, so that a portion of the roller brush assembly 20 can protrude downward beyond the cover 13. With this configuration, the bristles of the roller brush can be closer to the surface than the cover 13, or even in contact with the surface, allowing the cleaning device 100 to meander above debris and dust and sweep them into the suction chamber 10 without being blocked by the cover 13. The base 11 has an outlet 14 connected to the collector of the cleaning device 100, so that debris and dust swept into the suction chamber 10 can be guided into the collector of the cleaning device 100 through the outlet 14. The cover 13 is detachably connected to the base 11. In some embodiments, the cover 13 can be directly removed from the base 11. In some embodiments, the cover 13 can be rotated relative to the base 11 in a closed state (e.g., Figure 2A (as shown) and open state (as shown) Figure 2B and 3 The brush assembly 20 can be switched between the closed and open states (as shown). When the cover 13 is closed, the brush assembly 20 can be fixedly connected to the suction chamber 10. When the cover 13 is open, the brush assembly 20 can be removed from the suction chamber 10.

[0042] In some embodiments, such as Figures 2B to 4 As shown, the roller brush assembly 20 includes a mounting bracket 21 and a roller brush 23. In this disclosure, the roller brush 23 is a cantilever roller brush, with its fixed end A connected to the mounting bracket 21, and its free end B extending from the fixed end A along a first direction (i.e., the length direction of the roller brush 23, corresponding to...). Figures 2B to 4 The X-axis (as shown) extends. It is worth noting that... Figures 2B to 5 The document includes an X-axis and a Y-axis to further illustrate the spatial relationship of the components described herein. The X-axis and Y-axis are perpendicular to each other and together form a side plane, which in some embodiments is parallel to the surface to be cleaned on the cleaning device 100. The free end B of the roller brush 23 is closer to the outlet 14 of the suction chamber 10 than the fixed end A, as shown... Figure 3 As shown. The mounting bracket 21 is detachably fixed to the suction chamber 10, and the roller brush 23 is rotatably fixed to the mounting bracket 21 via at least one bearing. With this structure, the roller brush assembly 20 can be connected to the cleaning device 100 via the mounting bracket 21. When the cleaning device 100 is operating and the roller brush 23 rotates, the position of the mounting bracket 21 relative to the cleaning device 100 remains unchanged, thereby stabilizing the rotation of the roller brush 23. Stable rotation also reduces the vibration of the roller brush 23, thereby eliminating unpleasant noise generated by the roller brush 23 contacting the surface during cleaning.

[0043] In some embodiments, the roller brush 23 is rotatably connected to the mounting bracket 21 via a pivot 40, such as... Figure 5 As shown. The rotatable connection used in this article means that when one component is connected to another component, one component can rotate relative to the other component. Figure 5 A first exploded view of a roller brush assembly 20 according to certain aspects of this disclosure is shown. The rotating shaft 40 includes a first end non-rotatably connected to the roller brush 23 and a second end rotatably connected to a mounting bracket 21. When the rotating shaft 40 rotates, it causes the roller brush 23 to rotate, while the mounting bracket 21 remains in a fixed position relative to the suction chamber 10. The roller brush 23 includes a connecting groove 30 at its fixed end A for receiving the first end of the rotating shaft 40, such as... Figure 5 and Figure 6 As shown. The first end of the rotating shaft 40 can be detachably fixed to the roller brush 23 or integrally formed with the roller brush 23. Detachable fixing can include snap-fit ​​connections, screws, pins, clips, fasteners, etc. The second end of the rotating shaft 40 can be detachably fixed to the mounting bracket 21. Detachable fixing can include snap-fit ​​connections, screws, pins, clips, fasteners, etc. In some embodiments, the first end of the rotating shaft 40 can be detachably fixed to the mounting bracket 21, or the second end of the rotating shaft 40 can be detachably fixed to the roller brush 23, or both, so that the roller brush 23 can be removed from the mounting bracket 21 for easy replacement of the roller brush 23.

[0044] In some embodiments, the connecting groove 30 is along the length direction of the roller brush 23 (corresponding to...). Figure 5 The X-axis is shown. In some other embodiments, the connecting groove 30 extends along a direction offset from the length of the roller brush 23. The connecting groove 30 may be a well-shaped cylindrical cavity inside the roller brush 23, with its opening located at or near one end of the roller brush 23, such as the fixed end A. In some embodiments, the first end of the rotating shaft 40 is located within the connecting groove 30 and extends along the extending direction of the connecting groove 30. The second end of the rotating shaft 40 extends beyond the fixed end A of the roller brush 23. After assembly, the rotating shaft 40 can be considered as inserted into the connecting groove 30, with a portion of the rotating shaft 40 protruding from the opening, such as... Figure 6 As shown.

[0045] In some embodiments, the roller brush 23 has multiple bristles or strips for removing debris and dust from a surface during rotation. In some embodiments, to keep the roller brush 23 stable during rotation, the shaft 40 and mounting bracket 21 may be made of rigid or hard materials, such as metals, alloys, etc. In some other embodiments, the shaft 40 and mounting bracket 21 may be made of lighter materials, such as polymers (e.g., plastics) or carbon fiber, to reduce the overall weight of the roller brush assembly 20 and decrease its inertia. The lower the inertia of the roller brush assembly 20, the less likely the roller brush 23 is to detach from the cleaning device 100 due to excessive inertia during rotation. In some other embodiments, the shaft 40 and mounting bracket 21 may be made of a variety of materials. For example, the mounting bracket 21 may be made of metal and the shaft 40 of plastic, or the shaft 40 of metal and the mounting bracket 21 of plastic. In some embodiments, the mounting base 212 of the mounting bracket 21 is made of carbon fiber to reduce weight, while the connector 214 of the mounting bracket is made of metal for stable support.

[0046] In some embodiments, the rotating shaft 40 is detachably connected to the drive unit of the cleaning device 100, and in most cases, additional force is required to detach the rotating shaft 40 from the drive unit. Therefore, the rotating shaft 40 may be made of one or more of metal, carbon fiber, high ultimate tensile strength (UTS) polymer materials (e.g., polycarbonate, polystyrene, polyoxymethylene, etc.), or other suitable materials with sufficient strength to prevent damage or deformation of the rotating shaft 40 during disassembly. In some embodiments, the rotating shaft 40 is integrally formed with the roller brush 23.

[0047] Please refer to Figures 4 to 6 The mounting bracket 21 may include a mounting base 212 and a connector 214. The mounting base 212 is used to secure the mounting bracket 21 to the cleaning device 100, and the connector 214 extends from the center of the mounting base 212 along the length of the roller brush 23 and is received in a connecting groove 30. In some embodiments, the center of the mounting base 212 may be one of the following: a geometric center, a center of gravity, or the center of a plane defined by one side of the mounting base 212. In some embodiments, the connector 214 is a hollow cylinder such that a second end 40-2 of the rotating shaft 40 can be positioned in the hollow cylinder. The rotating shaft 40 can be considered as being inserted into the connector 214. In some embodiments, the connector 214 is received by the connecting groove 30 of the roller brush 23. The mounting bracket 21 may also include at least one support arm 216.

[0048] Please refer to Figure 5The mounting base 212 includes a first side 212-1 and a second side 212-2 opposite to the first side 212-1. A side surface 212S is located between the first side 212-1 and the second side 212-2 and is perpendicular to the first side 212-1 and the second side 212-2. The first side 212-1 is connected to the roller brush 23. In some embodiments, the side surface 212S of the mounting base 212 does not need to contact the cleaning device 100 for the mounting base 212 to be connected to the cleaning device 100. In some embodiments, the pivot 40 passes through the connector 214 and the mounting base 212 and extends through the second side 212-2 of the mounting base 212. In some embodiments, the first side 212-1 of the mounting base 212 abuts against the fixed end A of the roller brush 23 to reduce the space required for assembly. In some other embodiments, there is a gap between the first side 212-1 of the mounting base 212 and the fixed end A of the roller brush 23 to minimize friction between the mounting base 212 and the roller brush 23 during cleaning.

[0049] In some embodiments, please refer to Figure 5 The connector 214 is located at the geometric center of the mounting base 212 and extends from the first side 212-1 of the mounting base 212 toward the roller brush 23. For example... Figure 5 As shown, connector 214 extends into connecting groove 30 and accommodates shaft 40. Shaft 40 passes through connector 214 and mounting base 212, such that a second end of shaft 40 extends beyond the second side 212-2 of mounting base 212 and connects to connecting cap 35. Connecting cap 35 and the second end of shaft 40 can be directly connected via snap-fit, screw, pin, clip, fastener, etc. Mounting base 212 is clamped between connecting cap 35 and roller brush 23. In some embodiments, connector 214 is non-removably attached to the first side 212-1 of mounting base 212 by means including gluing, riveting, welding, etc. In some embodiments, connector 214 and mounting base 212 are separately molded and therefore detachable from each other. For example, connector 214 is detachably mounted to the first side 212-1 of mounting base 212 by means including snap-fit, screw, pin, clip, fastener, etc. In some embodiments, the end of the connector 214 connected to the mounting base 212 extends into the mounting base 212. In some other embodiments, the end of the connector 214 connected to the mounting base 212 terminates at a first side 212-1 of the mounting base 212 and is therefore located outside the first side 212-1 of the mounting base 212.

[0050] In some embodiments, the connecting cap 35 is located on the second side 212-2 of the mounting base 212, and the connecting cap 35 is fixedly connected to the rotating shaft 40 (for example, as described above, the connecting cap 35 is directly connected to the second end of the rotating shaft 40), and the rotating shaft 40 can rotate together with the connecting cap 35. The connecting cap 35 can be connected between the rotating shaft 40 and the drive unit to enhance the dynamic linkage between the two, so that the drive unit can drive the rotating shaft 40 to rotate more effectively. The connecting cap 35 can also eliminate wear on the rotating shaft 40 by directly connecting the rotating shaft 40 to the drive unit. In some embodiments, the connecting cap 35 is detachably connected to the rotating shaft 40 by means of snap-fit ​​connection, screws, pins, clips, fasteners, etc. This allows for convenient replacement of the connecting cap 35 when needed. In some embodiments, the connecting cap 35 is fixedly connected to the rotating shaft 40 by means of gluing, riveting, welding, etc.

[0051] In some embodiments, when the second end of the shaft 40 does not extend beyond the mounting base 212, at least a portion of the connecting cap 35 may extend into the mounting base 212 to connect with the shaft 40. A gap exists between the connecting cap 35 and the mounting base 212 to prevent wear during rotation of the connecting cap 35. In some embodiments, at least one bearing is located between the connecting cap 35 and the mounting base 212 such that the mounting base 212 does not rotate or shift due to rotation of the connecting cap 35.

[0052] In some embodiments, such as Figure 5 and Figure 6 As shown, the connector 214 can be connected to the roller brush 23 via a bearing assembly 50. The bearing assembly 50 includes a first bearing 51 connected to a first end of the connector 214 near the mounting base 212 and a second bearing 53 connected to a second end of the connector 214 away from the mounting base 212. During rotation of the roller brush 23, the mounting base 212 and the connector 214 remain stationary relative to the suction chamber 10. The bearing assembly 50 can separate the connector 214 from the connecting groove 30 of the roller brush 23 and form a gap between them to reduce friction. In some embodiments, the first bearing 51 and the second bearing 53 are located at opposite ends of the connector 214 to maintain the stability of the connector 214 during operation. With the help of the first bearing 51 and the second bearing 53, although the connector 214 has a relatively long length along the axis of rotation of the roller brush 23, the connector 214 will not deviate from its position, for example, by colliding with the connecting groove 30, when the roller brush 23 rotates. Therefore, the stability of the roller brush assembly 20 is improved.

[0053] In some embodiments, such as Figure 5 and Figure 6As shown, the mounting bracket 21 further includes at least one support arm 216, which extends from the edge of the mounting base 212 along the length of the roller brush 23. The at least one support arm 216 is used to detachably secure the mounting bracket 21 to the suction chamber 10. In some embodiments, such as Figure 5 As shown, there can be at least two support arms 216, and the two support arms 216 are symmetrically arranged with respect to the connector 214. One end of the support arm 216 is integrally formed with the mounting base 212, and the other end extends along the length direction of the roller brush 23. The two support arms 216 can be parallel to each other, and in some embodiments, the lengths of the two support arms are equal. By providing at least one support arm 216, the contact area between the mounting bracket 21 and the suction cavity 10 can be increased, thereby enhancing the stability of the mounting bracket 21. The length of the support arm 216 should not be too long, for example, greater than the length of the roller brush 23. This not only increases the manufacturing cost but also makes the installation of the roller brush 23 and the mounting bracket 21 difficult and easily leads to the support arm 216 breaking from the mounting base 212. The length of the support arm 216 should also not be too short, for example, only one-tenth the length of the roller brush 23. This would not provide sufficient support to stabilize the roller brush 23 and prevent the roller brush 23 from deviating from its axis of rotation during rotation. In some embodiments, the ratio between the length of the support arm 216 and the length of the roller brush 23 is between 1:1 and 1:10 (inclusive), thus allowing the roller brush 23 to be mounted relatively easily onto the mounting bracket 21 while maintaining stability of the roller brush 23 during rotation. For example, this ratio can be 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, 1:10, or any value between two of the listed ratios. Figure 5 and Figure 6 In the example shown, the length of the support arm 216 is one-fifth the length of the roller brush 23.

[0054] In some embodiments, please refer to Figure 3 and Figure 7 The mounting bracket 21 is fixed between the base 11 and the cover 13 within the suction chamber 10 by at least one pair of action and reaction forces acting on the mounting bracket 21 and the suction chamber 10. Please refer to... Figure 7 The suction chamber 10 includes a first end 191 and a second end 193 located away from the first end 191 in the X direction. The roller brush 23 is connected to the suction chamber 10 through the first end 191. The outlet 14 is located near the second end 193.

[0055] Figure 8A cross-sectional view of a suction cavity 10 according to certain aspects of this disclosure is shown. The suction cavity 10 includes a first cavity 151, a second cavity 153, and a third cavity 155. The first cavity 151 is located at a first end 191 of the suction cavity 10 and is used to receive a mounting base 212. The second cavity 153 is located near the first cavity 151 and is used to receive a support arm 216. In some embodiments, the first cavity 151 and the second cavity 153 are connected to each other to integrally receive the mounting base 212 and the support arm 216. In some embodiments, the first cavity 151 and the second cavity 153 are isolated from each other to receive the mounting base 212 and the support arm 216, respectively. Figure 7 and Figure 8 As shown, the first cavity 151 and the second cavity 153 are formed within the side walls of the base 11 and the cover 13. The third cavity 155 may be significantly larger than the first cavity 151 and the second cavity 153. The third cavity 155 may be opened by the side walls of the base 11 and the cover 13 and is used to accommodate the roller brush 23. When the roller brush assembly 20 is connected to the suction chamber 10 and the cover 13 is connected to the base 11, the mounting base 212 is restricted and fixed by the first cavity 151, the support arm 216 is restricted and fixed by the second cavity 153, and the roller brush 23 is rotatably located within the third cavity 155.

[0056] In some embodiments, please refer to Figure 7 The first cavity 151 may be formed by a first portion 111 of the sidewall of the base 11 and a first portion 131 of the sidewall of the cover 13. Both sidewalls are located at or near the first end 191 of the suction cavity 10. Both the first portion 111 and the first portion 131 may be recesses that accommodate a portion of the mounting base 212 of the mounting bracket 21. When the cover 13 is closed, the first portion 111 and the first portion 131 form the first cavity 151, which may have the same shape as the mounting base 212, such that the mounting base 212 is fixed within the first cavity 151 by a first pair of action-reaction forces acting between the mounting base 212 and the suction cavity 10. For example, the shapes of the mounting base 212 and the first cavity 151 may include cylinders, ellipsoids, cubes, polyhedra, or any combination of two or more of these shapes. The first pair of action-reaction forces includes a first action force and a first reaction force. The first force is generated by the mounting base 212 and acts on at least one of the first portion 111 of the base 11 and the first portion 131 of the cover 13. The first reaction force is generated by at least one of the first portion 111 of the base 11 and the first portion 131 of the cover 13 and acts on the mounting base 212. Since the mounting base 212 is stably fixed by the first cavity 151, the mounting bracket 21 can remain stationary during the rotation of the roller brush 23.

[0057] In some embodiments, please refer to Figure 7The second cavity 153 can be formed by a second portion 113 of the sidewall of the base 11 and a second portion 133 of the sidewall of the cover 13. The second portion 113 of the base 11 is located adjacent to the first portion 111 of the base 11, and the second portion 133 of the cover 13 is located adjacent to the first portion 131 of the cover 13. In some embodiments, both the second portion 113 and the second portion 133 are recesses that accommodate a portion of the support arm 216 of the mounting bracket 21. When the cover 13 is in the closed state, the second portion 113 and the second portion 133 form the second cavity 153, which can have the same shape as the support arm 216, such that the support arm 216 can be fixed in the second cavity 153 by a second pair of action-reaction forces. For example, as Figure 7 As shown, the second portion 113 of the base 11 can be a groove with the same shape as the first side of the support arm 216. The second portion 113 includes a bottom surface 1131 located at the bottom of the groove and two side surfaces extending from the bottom surface 1131 to the top of the groove. For example, as Figure 7 As shown, the second portion 133 of the cover 13 can be a recess with the same shape as the second side of the support arm 216. The second portion 133 is as flat as the second side of the support arm 216. The second action-reaction force includes a second action force and a second reaction force. The second action force is generated by the support arm 216 and acts on at least one of the second portion 113 of the base 11 and the second portion 133 of the cover 13. The second reaction force is generated by at least one of the second portion 113 of the base 11 and the second portion 133 of the cover 13 and acts on the support arm 216. Since the support arm 216 is stably fixed by the second cavity 153, the mounting bracket 21 can be more stable during the rotation of the roller brush 23.

[0058] In some embodiments, the generation of the first pair of action-reaction forces and the second pair of action-reaction forces is due to the connection between the cover 13 and the base 11, and the detachable fixing of the support arm 216 between the base 11 and the cover 13. Please refer to... Figure 2A and Figure 2BThe base 11 is connected to the cover 13 via a connecting assembly 16. In some embodiments, the connecting assembly 16 includes a snap-fit ​​member 162 disposed on the cover 13 and a corresponding mating member 164 disposed on the base 11. In some embodiments, the snap-fit ​​member 162 may be disposed on the base 11, and the corresponding mating member 164 may be disposed on the cover 13. The relative position and number of the connecting assemblies 16 can be designed as needed and are not limited to the above embodiments. In some embodiments, multiple connecting assemblies 16 are disposed on both the first side 105 and the second side 107 of the suction cavity 10. In some embodiments, multiple connecting assemblies 16 are disposed only on one side of the suction cavity 10, while the other side of the suction cavity 10 is connected by other connecting members, such as springs, bearings, magnets, etc. In some embodiments, the latching member 162 may be a tongue extending laterally from the surface of the cover 13 for engaging with the base 11, and the mating member 164 may be an opening on the base 11 corresponding to the latching member 162. When the cover 13 is engaged with the base 11, the tongue is received and locked by the opening, preventing the cover 13 from detaching from the base 11. In some embodiments, the latching member 162 and the corresponding mating member 164 may also have other structures capable of fixing the base 11 and the cover 13, and the specific structure of the connecting assembly 16 is not limited to the above embodiments.

[0059] In some embodiments, please refer to Figure 7 The suction chamber 10 also includes at least one flexible protrusion 132, which can be disposed between the support arm 216 and the suction chamber 10 when the base 11 is connected to the cover 13. In some embodiments, the flexible protrusion 132 can be disposed on any one of the second portion 113 of the base 11, the second portion 133 of the cover 13, or the support arm 216, such that the flexible protrusion 132 can be located between the support arm 216 and the second portion 133 of the cover 13 or between the support arm 216 and the second portion 113 of the base 11. In some embodiments, two or more flexible protrusions 132 are provided on both sides of the support arm 216. The flexible protrusions 132 may include flexible materials such as silicone, rubber, polyimide, and polyester. When the cover 13 is fixedly connected to the base 11, the flexible protrusions 132 deform under the action of the second pair of action-reaction forces between the support arm 216 and the suction cavity 10. The second pair of action-reaction forces is formed by the pressure generated by the deformation of the flexible protrusions 132, which can further improve the stability of the support arm 216 in the second cavity 153.

[0060] In some embodiments, regardless of whether the cover 13 is connected to the base 11, the support arm 216 is detachably fixed to the base 11 by at least one fastening component, generating a first pair of action-reaction forces and a second pair of action-reaction forces. At least one fastening component may include a magnetic attraction component 60, such as... Figure 9 As shown. Figure 9The structure of a cleaning assembly 300 having a magnetic attraction component 60 according to certain aspects of this disclosure is shown. The magnetic attraction component 60 may include a first magnetic attraction element 611 disposed on a base 11 and a second magnetic attraction element 613 disposed on a mounting base 212. In some embodiments, one of the first magnetic attraction element 611 and the second magnetic attraction element 613 includes a magnetic material, such as a permanent magnet, electromagnet, etc., while the other includes a non-magnetic material that can be attracted by a magnetic material, such as iron, nickel, cobalt, alloys thereof, etc. In some embodiments, both the first magnetic attraction element 611 and the second magnetic attraction element 613 include magnetic materials. In some embodiments, when one of the first magnetic attraction element 611 and the second magnetic attraction element 613 includes a magnetic material, the other may be omitted when the corresponding mounting base 212 or base 11 is made of iron, nickel, cobalt, alloys thereof, etc., and is capable of attracting magnets.

[0061] In some embodiments, when the mounting base 212 is located within the first cavity 151, the first magnetic member 611 and the second magnetic member 613 attract each other. The magnetic force between the first magnetic member 611 and the second magnetic member 613 fixes the mounting base 212 and the base 11 together. The greater the magnetic force, the more stable the connection between the mounting base 212 and the base 11. When a force opposite to the direction of the magnetic force and greater than the magnetic force is applied to the mounting base 212, the mounting base 212 can be separated from the base 11. By adjusting the material and size of one or both of the first magnetic member 611 and the second magnetic member 613, the magnetic force between them can be adjusted as needed.

[0062] In some embodiments, at least one of the first magnetic attractor 611 and the second magnetic attractor 613 is an electromagnet. Please refer to... Figure 9For example, the first magnetic element 611 is an electromagnet, and the magnetic assembly 60 also includes a control circuit 63, a switch 65, and a detector 67. The control circuit 63 is coupled to the first magnetic element 611 and is used to adjust the magnetic force between the first magnetic element 611 and the second magnetic element 613 by controlling the current flowing through the first magnetic element 611. The detector 67 is used to detect the distance between the first magnetic element 611 and the second magnetic element 613. The switch 65 is used to automatically activate the control circuit 63 in response to a distance less than a threshold distance. For example, the threshold distance between the first magnetic element 611 and the second magnetic element 613 is 1 centimeter (cm). When the distance between the first magnetic element 611 and the second magnetic element 613 is less than or equal to 1 cm, the detector 67 generates a signal indicating that the switch 65 should be closed, thereby causing the control circuit 63 to generate a magnetic force between the first magnetic element 611 and the second magnetic element 613. In this way, the mounting base 212 can be fixedly connected to the base 11. When the distance between the first magnetic member 611 and the second magnetic member 613 is greater than 1 cm, the detector 67 generates a signal indicating that the switch should be turned off, thereby disabling the control circuit 63 and eliminating the magnetic force between the first magnetic member 611 and the second magnetic member 613. In this way, the mounting base 212 can be separated from the base 11.

[0063] In some embodiments, at least one fastening component includes a rotatable fastening component 70, such as Figure 10 As shown. Figure 10 A schematic block diagram of a cleaning assembly 400 having a rotatable fastening assembly 70 according to certain aspects of this disclosure is shown. Figure 10 This is a simplified version of the schematic block diagram used to illustrate the structure of the fastening assembly, and details of the cleaning assembly 400 are omitted for brevity. It is understood that, except for the rotatable fastening assembly 70, the cleaning assembly 400 may have the same or similar structure as the cleaning assembly 200. Figure 10 The dimensions and shapes of the components of the rotatable fastening assembly 70 are illustrative and should not be limited to the embodiments described herein, and any suitable structure can be applied to this embodiment under the teachings of this disclosure.

[0064] Please refer to Figure 10 The rotatable fastening assembly 70 may include a first fastener 71 rotatably disposed on the base 11 and adjacent to a first side 113A of a second portion 113 of the base 11, and a corresponding mating member 73 disposed on the base 11 and adjacent to a second side 113B of the second portion 113 of the base 11. In some embodiments, the positions of the first fastener 71 and the mating member 73 may be interchanged. It should be understood that the positions of the first fastener 71 and the mating member 73 relative to other components of the suction cavity may be changed, and should not be limited to the embodiments described above.

[0065] like Figure 10As shown, the first fastener 71 is rotatably fixed to the base 11 and can rotate freely to move closer to or further away from the mating member 73. The first fastener 71 may be made of a rigid or hard material, such as metal, alloy, etc. When the first fastener 71 is engaged with the mating member 73, the relative position between the first fastener 71 and the base 11 is fixed, and the corresponding support arm 216 is locked in the second cavity 153 by the first fastener 71. Therefore, the mounting bracket 21 can be fixed to the base 11 without attaching the cover 13 to the base 11. When the first fastener 71 is disengaged from the mating member 73, the support arm 216 can be removed from the second cavity 153. In some embodiments, each support arm 216 is provided with more than one rotatable fastening assembly 70, and the number of rotatable fastening assemblies 70 is greater than or equal to the number of support arms 216.

[0066] In some embodiments, at least one fastening component includes a slotted fastening component 80, such as Figure 11 As shown. Figure 11 A schematic block diagram of a cleaning assembly 500 having a slotted fastening assembly 80 according to certain aspects of this disclosure is shown. Figure 11 This is also a simplified version of the schematic block diagram used to illustrate the structure of the fastening assembly, and details of the cleaning assembly 500 are omitted for brevity. It should be understood that, except for the slotted fastening assembly 80, the cleaning assembly 500 may have the same or similar structure as the cleaning assembly 200. Figure 11 The dimensions and shapes of the components of the slotted fastening assembly 80 are illustrative and should not be limited to the embodiments described herein, and any suitable structure can be applied to this embodiment under the teachings of this disclosure.

[0067] Please refer to Figure 11 The slotted fastening assembly 80 may include a pair of slots 83 disposed on the base 11 and a second fastener 81 slidable into the pair of slots 83. The slots 83 extend parallel to the support arm 216, which is located between the pair of slots 83. Figure 11 As shown, the two slots 83 are of the same length, and the free end of the support arm 216 away from the mounting base 212 extends beyond the first end 83A of the slot 83 but does not reach the second end 83B of the slot 83. The second fastener 81 is provided with two connectors that are respectively connected to each slot 83, so the second fastener 81 can slide along the slot 83 and stop at any position between the first end 83A and the second end 83B.

[0068] like Figure 11As shown, the second fastener 81 can be made of a rigid or hard material, such as metal, alloy, etc. When the second fastener 81 is located at the first end 83A of the slot 83, the second fastener 81 abuts against the corresponding support arm 216 to fix the support arm 216 in the second cavity 153, thereby allowing the mounting bracket 21 to be fixed to the base 11 without connecting the cover 13 to the base 11. When the second fastener 81 is located at the second end 83B of the slot 83, the second fastener 81 is away from the corresponding support arm 216, and the support arm 216 can be separated from the second cavity 153.

[0069] In some embodiments, at least one fastening component includes a resilient fastening component 90, such as Figure 12 As shown. Figure 12 A schematic block diagram of a cleaning assembly 600 having a resilient fastening component 90 according to certain aspects of this disclosure is shown. Figure 12 This is also a simplified version of the schematic block diagram used to illustrate the structure of the fastening assembly; for the sake of brevity, details of the cleaning assembly 600 have been omitted. It should be understood that, except for the resilient fastening assembly 90, the cleaning assembly 600 may have the same or similar structure as the cleaning assembly 200. Figure 12 The dimensions and shapes of the components of the elastic fastening assembly 90 are illustrative and should not be limited to the embodiments described herein. Any suitable structure can be applied to this embodiment under the teachings of this disclosure.

[0070] Please refer to Figure 12 The resilient fastening assembly 90 may include a third fastener 95 located on the support arm 216 and an engagement member 112 located on the base 11. In some embodiments, such as Figure 12 As shown, the third fastener 95 can be located in a slot 2162 on the support arm 216. The slot 2162 extends along the Y direction and passes through the support arm 216, allowing the third fastener 95 to extend beyond the slot 2162. The engaging member 112 can be a slot on the base 11 corresponding to the third fastener 95. The engaging member 112 may include a locking portion for securing the third fastener 95 to the base 11 and an opening connected to the locking portion, allowing the third fastener 95 to move in and out of the locking portion.

[0071] Please refer to Figure 12The third fastener 95 includes a rigid portion 92 and an elastic member 94 connected to the rigid portion 92. The length of the third fastener 95 changes as the elastic member 94 deforms. For example, when the elastic member 94 is compressed, the rigid portion 92 retracts into the slot 2162 of the support arm 216; when the elastic member 94 is released, the rigid portion 92 extends out of the slot 2162 of the support arm 216 and is fixedly connected to the coupling member 112 on the base 11. In some embodiments, the rigid portion 92 includes a coupling portion 921 disposed on the top of the rigid portion 92, a connecting portion 923 for connecting the coupling portion 921 and the elastic member 94, and a sliding portion 925 located outside the slot 2162.

[0072] In some embodiments, the coupling portion 921 and the connecting portion 923 may be made of rigid or hard materials, such as metals, alloys, etc. The materials of the coupling portion 921 and the connecting portion 923 may be the same or different. See also Figure 12 Both the coupling portion 921 and the connecting portion 923 extend in the Y direction, i.e., in the same direction as the extension of the slot 2162. The diameter of the connecting portion 923 is slightly smaller than the diameter of the slot 2162 so that the third fastener 95 can slide stably and smoothly into the slot 2162. In some embodiments, the coupling portion 921 has a hook-shaped end, and the diameter of the coupling portion 921 is smaller than the diameter of the connecting portion 923. For example, as... Figure 12 As shown, the diameter of the coupling portion 921 is half the diameter of the connecting portion 923, and the coupling portion 921 is located on the side of the slot 2162 near the hook-shaped end. In some embodiments, although the coupling portion 921 is made of a rigid material, it can be slightly deformed to a certain extent and then return to its original shape.

[0073] In this embodiment, when the elastic member 94 is compressed, both the coupling portion 921 and the connecting portion 923 are located within the slot 2162, and the coupling portion 921 is in a deformed state, allowing the mounting bracket 21 to be detached from the base 11. When the elastic member 94 is released, the coupling portion 921 extends out of the slot 2162, and its hook-shaped end extends into the opening of the connector 112, engaging with the locking portion of the connector 112. Thus, the support arm 216 is fixedly connected to the base 11, and the mounting bracket 21 does not need to be connected to the base 11 to fix the cover 13 to the base 11. The sliding portion 925 is connected to the connecting portion 923 and is located outside the slot 2162. The width of the sliding portion 925 is slightly larger than the slot 2162, allowing the sliding portion 925 to slide stably on the slot 2162. By changing the position of the sliding portion 925, the elastic member 94 can be changed from a compressed state to a released state, and vice versa.

[0074] Figure 13 A schematic block diagram of a cleaning assembly 700 having another resilient fastening component 90 according to certain aspects of this disclosure is shown. Please refer to... Figure 13Similar to the resilient fastening component 90 in cleaning component 600, the resilient fastening component 90 in cleaning component 700 also includes a third fastener 95' in a slot 2164 in support arm 216 and a mating member 114 on base 11. The difference between cleaning component 700 and cleaning component 600 is that slot 2164 extends in the X direction, and its opening corresponds to the mating member 114 on base 11.

[0075] Similar to the third fastener 95, the third fastener 95' also includes a rigid portion 92 and an elastic member 94 connected to the rigid portion 92. The rigid portion 92 further includes a coupling portion 921, a connecting portion 923, and a sliding portion 925. For example... Figure 13 As shown, the coupling portion 921 is perpendicular to the connecting portion 923. When the elastic member 94 is compressed, the coupling portion 921 is located in the opening of the mating member 114, and the support arm 216 can be separated from the base 11. When the elastic member 94 is released, the coupling portion 921 moves forward, and the hook-shaped end of the coupling portion 921 extends into the locking portion of the mating member 114. Therefore, the support arm 216 is fixedly connected to the base 11, and the mounting bracket 21 can be fixed to the base 11 without connecting the cover 13 to the base 11.

[0076] In some embodiments, at least one fastening component includes a threaded component 98, such as Figure 14 As shown. Figure 14 A schematic block diagram of a cleaning assembly 800 having a threaded assembly 98 according to certain aspects of this disclosure is shown. Figure 14 This is also a simplified version of the schematic block diagram used to illustrate the structure of the fastening assembly; for the sake of brevity, details of the cleaning assembly 800 have been omitted. It should be understood that, except for the threaded assembly 98, the cleaning assembly 800 may have the same or similar structure as the cleaning assembly 200. Figure 14 The dimensions and shapes of the components of the threaded assembly 98 are exemplary and should not be limited to the embodiments described herein. Any suitable structure can be applied to this embodiment under the teachings of this disclosure.

[0077] Please refer to Figure 14 The threaded assembly 98 may include a first through hole through the support arm 216 and a second hole on the base 11 corresponding to the first through hole. The threaded assembly 98 also includes a nut that mates with the first through hole and the second hole. When the nut passes through the first through hole and the second hole, the support arm 216 is fixedly connected to the base 11. When the nut is removed from the first through hole and the second hole, the support arm 216 can be separated from the base 11.

[0078] Figures 9 to 14Six embodiments are illustrated, employing different types of fastening assemblies for securely connecting the support arm 216 to the base 11 when the cover 13 is not connected to the base 11. It should be noted that in some embodiments, the aforementioned fastening assemblies can be combined with each other. For example, the cleaning assembly may include at least two components selected from combinations of magnetic assembly 60, rotatable fastening assembly 70, slotted fastening assembly 80, fastening assembly 90, or threaded assembly 98. The fastening assembly may also include any other suitable structure capable of securely connecting the support arm 216 to the base 11. It should be understood that the specific structures of the fastening assemblies described herein should not limit the scope of this disclosure, and any fastening assembly capable of securely connecting the support arm 216 to the base 11 under the teachings of this disclosure should fall within the scope of this disclosure.

[0079] In one aspect, embodiments of this disclosure provide a suction chamber assembly for a cleaning device. The suction chamber assembly includes a suction chamber, a mounting bracket, and a roller brush. The suction chamber includes a base connected to the cleaning device and a cover connected to the base. The base includes an outlet, and the cover includes an opening. The mounting bracket is detachably secured to the suction chamber. The roller brush includes a fixed end connected to the mounting bracket and a free end extending in the opposite direction to the fixed end. The mounting bracket is secured between the base and the cover within the suction chamber by at least one pair of action and reaction forces acting between the mounting bracket and the suction chamber.

[0080] In some embodiments, the suction chamber includes a first end and a second end, a roller brush is connected to the first end, the second end is located away from the first end along a first direction, and the outlet is located near the second end.

[0081] In some embodiments, the mounting bracket includes a mounting base detachably fixed to the suction chamber and at least one support arm extending from the edge of the mounting base along a first direction.
