Description

Technical Field

[0057] Below, refer to Figures 1 to 17 Some embodiments of this application will be described in detail.

[0058] like Figures 1 to 3 As shown, a first aspect of this application provides a roller brush assembly 100. The roller brush assembly 100 is applied to a cleaning device. The roller brush assembly includes a main brush housing 1, a main brush 2, and a baffle 3.

[0059] Cleaning equipment refers to equipment used to clean work surfaces. Cleaning equipment includes, but is not limited to, vacuum cleaners, floor scrubbers, mops, and combined sweeper and mop machines. Work surfaces to be cleaned include, but are not limited to, floors, tiles, carpets, tabletops, or the surfaces of other objects and components.

[0060] The cleaning equipment includes a main body and a roller brush assembly 100. The roller brush assembly 100 is located within the main body. The main body is the primary supporting and load-bearing component of the cleaning equipment. The cleaning equipment's movement system, sensing system, control system, drive system, energy system, human-machine interaction system, and cleaning system are all located within the main body.

[0061] The roller brush assembly 100 can move along the X-direction on the working surface under the drive of the cleaning equipment's moving system. The roller brush assembly 100 is part of the cleaning system and is a key component of the cleaning equipment in the cleaning operation.

[0062] The working surface can refer to the working surface of the roller brush assembly 100. The roller brush assembly 100 can clean the working surface. The working surface can be in contact with the roller brush assembly 100. For example, when the cleaning equipment is operating on a floor, the roller brush assembly 100 is in contact with the floor. Then the floor can be considered as the working surface. It should be noted that the working surface can be a horizontal surface or a surface inclined relative to a horizontal surface (e.g., a slope). The working surface can be a plane or a curved surface.

[0063] The direction of travel X refers to the direction in which the roller brush assembly 100 moves along the working surface during the cleaning operation. It can also be understood as the direction in which the rear end of the roller brush assembly 100 faces the front end. During the cleaning operation, the front end of the roller brush assembly 100 passes the working surface before the rear end. The direction of travel X is the forward direction of the cleaning equipment. The direction in which the cleaning equipment moves backward is the opposite direction of travel X.

[0064] The main brush housing 1 is the outer protective shell of the roller brush assembly 100. An internal cavity 10 is formed within the main brush housing 1 to house the main brush 2, the rotating shaft, and other structural components that enable the function of the roller brush assembly 100. The main brush housing 1 provides protection and support for the main brush 2. During cleaning operations, if the roller brush assembly 100 collides with furniture, walls, or other objects, the main brush housing 1 reduces the likelihood of damage to the main brush 2, thereby extending its service life and reducing replacement costs.

[0065] For example, the main brush housing 1 and the main body of the cleaning device can be separate structures, which are then assembled together. The roller brush assembly 100 is fixedly connected to the main body through the fixed connection between the main brush housing 1 and the main body.

[0066] As another example, the main brush housing 1 and the main body of the cleaning device can be an integral structural component. That is, the main brush housing 1 can be part of the main body of the cleaning device.

[0067] In this embodiment, the main brush housing 1 is generally cylindrical. In some other embodiments, the main brush housing 1 may also be in the shape of a box or an irregular shape, or any other suitable shape. This embodiment does not specifically limit the shape of the main brush housing 1. Furthermore, this embodiment does not specifically limit the material of the main brush housing 1; any suitable material such as plastic or metal is within the scope of protection of this application.

[0068] The main brush 2 is rotatably connected to the main brush housing 1 for contacting the work surface. The main brush 2 rotates to sweep debris, hair, and foreign objects from the work surface into the air duct 200, where they are then drawn into the dust box 300 by the fan, thus cleaning the work surface. The number of main brushes 2 can be one or more (two or more). This embodiment does not specifically limit the number of main brushes 2.

[0069] For example, the main brush 2 may be a brush made of materials such as nylon or polypropylene. Alternatively, the main brush 2 may be a rubber brush. This application does not specifically limit the type of the main brush 2.

[0070] In some embodiments, the main brush 1 is detachably connected to the main brush housing 1. This allows the user to replace the main brush 1 according to the different types of work surfaces to be cleaned, thereby selecting the most suitable type of main brush 1 and improving the cleaning effect.

[0071] The rotation of the main brush 2 can include forward rotation and reverse rotation. Forward rotation means that the main brush 2 travels along the X-direction from front to back across the working surface. Reverse rotation means that the main brush 2 travels along the X-direction from back to front across the working surface.

[0072] When the main brush 2 rotates in the forward direction, the airflow generated by its rotation is conducive to drawing dust and debris from the working surface into the air duct 200, thereby improving the collection efficiency of dust, debris, and other foreign objects. Because the forward rotation of the main brush 2 can more effectively push dust and foreign objects into the air duct 200, these debris are easier to collect, thus reducing the possibility of dust splashing during cleaning and lowering the risk of secondary pollution.

[0073] However, when the cleaning equipment is used on carpets or other fabrics, the cleaning power of the main brush 2 may be slightly insufficient if it can only rotate in the forward direction. This is because carpets and similar surfaces have long fibers. Hair, dust, particles, and other foreign objects can get trapped under these fibers. The airflow generated by the forward rotation of the main brush 2 may push these foreign objects deeper into the fibers, thus affecting the cleaning effect.

[0074] In this embodiment, the main brush 2 can rotate in both the forward and reverse directions. When rotating in the reverse direction, the main brush 2 can lift dust and foreign objects into the air. Therefore, when the working surface of the cleaning equipment is a lint-covered surface, the reverse rotation of the main brush 2 can lift up the dust and foreign objects hidden in the lint, thereby improving the cleaning effect of the cleaning equipment.

[0075] Although the reverse rotation of the main brush 2 can better lift dust and foreign objects hidden in fabrics and other work surfaces, if the lifted dust and foreign objects are not effectively blocked and collected in time, they may spread in the air, causing secondary pollution.

[0076] like Figure 2 and Figure 3 As shown, the roller brush assembly 100 of this embodiment further includes a baffle 3. The baffle 3 is movably connected to the main brush housing 1. The baffle 3 is disposed on the front side of the main brush 2 along the traveling direction X of the cleaning device. The baffle 3 can move between a first position and a second position. The first position can be the position where the baffle 3 is lowered. At this time, the baffle 3 can block the front side of the main brush 2. The second position can be the position where the baffle 3 is raised, at which time the baffle 3 does not block the front side of the main brush 2.

[0077] Baffle 3 is located in front of main brush 2. When main brush 2 rotates clockwise, that is, when main brush 2 passes the working surface from front to back along the travel direction X, baffle 3 rises and is in the second position. When main brush 2 rotates counterclockwise, that is, when main brush 2 passes the working surface from back to front along the travel direction X, baffle 3 falls and is in the first position. Thus, when main brush 2 rotates clockwise, the relative area between the opening of main brush housing 1 and the working surface is increased, making it easier for large particles of debris to enter the main brush housing 1 and be sucked into dust box 300. Dust and foreign objects that are thrown forward by main brush 2 rotating counterclockwise are blocked by baffle 3. The blocked dust and foreign objects can enter the dust box 300 from above main brush 2 through air duct 200 under the action of the fan. In this way, dust and foreign objects can be pushed out from the working surface and the possibility of these dust and foreign objects spreading into the air can be reduced, further improving the cleaning effect of the cleaning equipment. Moreover, the lowering of the baffle 3 can reduce the relative area between the opening of the main brush housing 1 and the working surface, thereby improving the suction efficiency and further enhancing the cleaning effect.

[0078] The baffle 3 and the main brush housing 1 can be connected in various ways, including but not limited to rotational connection and sliding connection. In some embodiments, the baffle 3 is rotatably connected to the main brush housing 1. In some embodiments, the main brush housing 1 may be provided with an arc-shaped groove. The baffle 3 is supported in the arc-shaped groove in a manner that allows it to slide within the arc-shaped groove. In some embodiments, the baffle 3 can also be disposed on the main brush housing 1 in a manner that allows it to move up and down along the height direction of the roller brush assembly 100. Those skilled in the art should understand that any suitable connection method between the baffle 3 and the main brush housing 1, as long as it allows the baffle 3 to move relative to the main brush housing 1 between a first position and a second position, is within the protection scope of this application.

[0079] When baffle 3 is in the first position, the area it covers on the main brush 2 is greater than when it is in the second position. That is, when baffle 3 is in the first position, it better covers the main brush 2, thus reducing the possibility of dust and foreign objects spreading into the air and improving suction efficiency. When baffle 3 is in the second position, it better exposes the main brush 2, reducing the possibility of interference between the main brush 2 and baffle 3, and increasing the adsorption effect on large particles.

[0080] Specifically, the occlusion area of ​​the baffle 3 can be determined by the overlapping area of ​​the main brush 2 and the baffle 3 in the same projection plane, the exposed area of ​​the main brush 2, and the distance between the lowest position of the baffle 3 and the working surface.

[0081] For example, in the same projection plane perpendicular to the direction of travel X, the overlapping area of ​​the projection of the baffle 3 and the projection of the main brush 2 when the baffle 3 is in the first position is greater than the overlapping area of ​​the projection of the baffle 3 and the projection of the main brush 2 when the baffle 3 is in the second position. Therefore, it can be shown that the baffle 3 in the first position provides a better shielding effect on the main brush 2 compared to the second position.

[0082] For example, in the same projection plane perpendicular to the direction of travel X, the projected area of ​​the main brush 2 outside the projection range of the baffle 3 when the baffle 3 is in the first position is smaller than the projected area of ​​the main brush 2 outside the projection range of the baffle 3 when the baffle 3 is in the second position. That is, in the same projection plane perpendicular to the direction of travel X, the exposed area of ​​the main brush 2 relative to the baffle 3 when the baffle 3 is in the first position is smaller than the exposed area of ​​the main brush 2 relative to the baffle 3 when the baffle 3 is in the second position. Thus, it can be shown that when the baffle 3 is in the second position, more of the main brush 2 can be exposed. When the baffle 3 is in the first position, the main brush 2 can be better concealed.

[0083] For example, along the height direction of the roller brush assembly 100, when the baffle 3 is in the first position, the distance between the lowest point of the baffle 3 and the working surface is less than the distance between the lowest point of the baffle 3 and the working surface when the baffle 3 is in the second position. Since the main brush 2 is in contact with the working surface when the cleaning equipment is performing cleaning work, the smaller the distance between the baffle 3 and the working surface, the larger the area of ​​the main brush 2 covered by the baffle 3.

[0084] In this embodiment, the working surface may include, for example, a first working surface and a second working surface. When the cleaning device operates on the first working surface, the rotation direction of the main brush 2 is opposite to that when the cleaning device operates on the second working surface. The first working surface and the second working surface are different working surfaces. Therefore, the main brush 2 of the roller brush assembly 100 in this embodiment can rotate in different directions depending on the working surface of the cleaning device. This ensures that the main brush 2 of the roller brush assembly 100 can achieve a good cleaning effect regardless of the working surface during operation, thus improving the user experience.

[0085] For example, the first working surface and the second working surface can be working surfaces with different roughness.

[0086] As another example, the first working surface and the second working surface can be working surfaces made of different materials. Specifically, the first working surface includes a hard working surface, and the second working surface includes a carpet.

[0087] Hard working surfaces include, but are not limited to, floors, tiles, walls, or other hard, smooth surfaces. For example... Figure 3 As shown, when the cleaning equipment is working on the first working surface, the main brush 2 passes through the first working surface from front to back along the travel direction X. At this time, the baffle 3 is in the second position, meaning that the baffle 3 will not cause excessive obstruction to the main brush 2. This helps improve the cleaning effect of the cleaning equipment on hard working surfaces.

[0088] like Figure 2 As shown, when the cleaning equipment is working on the second working surface, the main brush 2 passes through the second working surface from back to front along the travel direction X. At this time, the baffle 3 is in the first position. That is, the baffle 3 provides some obstruction to the front of the main brush 2. Therefore, while meeting the cleaning effect requirements for working surfaces such as carpets, it reduces the possibility of dust and foreign objects being re-spread into the air.

[0089] Of course, those skilled in the art will understand that a second working surface is not limited to carpets. In some embodiments, simulated lawns, woven mats, blankets, etc., may also be considered a second working surface.

[0090] In this embodiment, when the cleaning equipment is working on the first working surface, the baffle 3 is in the second position. When the cleaning equipment is working on the second working surface, the baffle 3 is in the first position.

[0091] In some embodiments of this application, the baffle 3 is rotatably connected to the main brush housing 1. Rotational connection offers high motion precision, smooth motion, and a compact structure, thereby improving the space utilization of the roller brush assembly 100 and promoting its miniaturization and weight reduction. Furthermore, the rotational connection requires fewer components, thus reducing production costs.

[0092] Of course, those skilled in the art will understand that the baffle 3 can also be movably connected to the main brush housing 1 by any other suitable means, such as a sliding connection.

[0093] In some embodiments of this application, such as Figure 4 As shown, the roller brush assembly 100 also includes a first drive mechanism 4 and a first transmission mechanism 5. The first drive mechanism 4 is disposed on the main brush housing 1. The first transmission mechanism 5 is circumferentially connected to the first drive mechanism 4. The first transmission mechanism 5 is circumferentially connected to the main brush 2 and the baffle 3, and the main brush 2 and the baffle 3 rotate in opposite directions.

[0094] The first drive mechanism 4 is used to drive the main brush 2 and the baffle 3 to rotate circumferentially. For example, the first drive mechanism 4 can be a drive component that outputs rotational power, such as a motor or rotary cylinder, or a drive component that outputs linear power, such as an electric telescopic cylinder or a pneumatic / hydraulic telescopic cylinder. As a specific example, the first drive mechanism 4 can be a servo motor, which has high precision and fast response speed.

[0095] The first transmission mechanism 5 transmits power from the first drive mechanism 4 to the main brush 2 and the baffle 3. The first transmission mechanism 5 can change the output torque of the first drive mechanism 4 to meet the motion requirements of the main brush 2 or the baffle 3. Alternatively, the first transmission mechanism 5 can change the motion form of the first drive mechanism 4 to meet the motion requirements of the main brush 2 or the baffle 3. For example, it can convert a drive component that outputs linear power into rotational power. The first transmission mechanism 5 includes, but is not limited to, gear transmission mechanisms, chain transmission mechanisms, pulley transmission mechanisms, friction wheel transmission mechanisms, etc.

[0096] In this embodiment, the first transmission mechanism 5 is circumferentially connected to the first drive mechanism 4. Furthermore, the first transmission mechanism 5 is circumferentially connected to the main brush 2 and the baffle 3. Circumferential transmission connection is a connection method used to transmit circumferential (i.e., rotational) force and motion.

[0097] Specifically, in this embodiment, the first driving mechanism 4 includes a motor, such as a servo motor. The output end of the first driving mechanism 4 is connected to the first transmission mechanism 5, and is used to drive the first transmission mechanism 5 to rotate. The main brush 2 includes a main brush shaft. The baffle 3 includes a baffle shaft. Both the main brush shaft and the baffle shaft are connected to the first transmission mechanism 5, so that they can rotate together under the drive of the first transmission mechanism 5.

[0098] For example, circumferential transmission connections can be achieved through methods such as key connections, spline connections, interference fits, or pin connections. This application does not specifically limit the method of circumferential transmission connection.

[0099] In this embodiment, the main brush 2 and the baffle 3 can rotate together via the first transmission mechanism 5 and a first drive mechanism 4, which helps to reduce the number of drive mechanisms and lower production costs. Furthermore, it also helps to reduce the weight and space occupancy of the roller brush assembly 100.

[0100] Furthermore, in this embodiment, when the main brush 2 rotates in the forward direction, the main body 31 of the baffle 3 (described below) needs to rotate to a second position away from the main brush 2. When the main brush 2 rotates in the reverse direction, the main body 31 of the baffle 3 needs to rotate to a first position closer to the main brush 2. Therefore, the main brush 2 and the baffle 3 rotate in opposite directions via the first transmission mechanism 5.

[0101] The structure of the first transmission mechanism 5 will be described in detail below.

[0102] The first transmission mechanism 5 includes a main brush drive component 51, an intermediate drive component 52, and a baffle drive component 53, which are connected in a circumferential direction. The main brush drive component 51 and the baffle drive component 53 rotate in opposite directions via the intermediate drive component 52. The main brush drive component 51 is connected to the main brush 2, and the baffle drive component 53 is connected to the baffle 3.

[0103] In this embodiment, the first drive mechanism 4 is connected to the main brush drive component 51 or the main brush 2.

[0104] Specifically, if the first drive mechanism 4 is connected to the main brush drive member 51, the drive end of the first drive mechanism 4 is connected to the main brush drive member 51, thereby driving the main brush drive member 51 to rotate. The main brush drive member 51 drives the main brush 2 connected to it to rotate, and also drives the intermediate drive member 52 that cooperates with it to rotate. The intermediate drive member 52 drives the baffle drive member 53 to rotate. The baffle drive member 53 drives the baffle 3 connected to it to rotate. Thus, the rotation of the main brush 2 and the baffle 3 can be driven together by a single first drive mechanism.

[0105] If the first drive mechanism 4 is connected to the main brush 2, the drive end of the first drive mechanism 4 is connected to the main brush 2 and drives the main brush 2 to rotate. The main brush 2 drives the main brush transmission component 51 connected to it to rotate. The subsequent transmission steps are the same as the transmission steps of the first drive mechanism 4 and the main brush transmission component 51 described above, and will not be described in detail here.

[0106] The main brush drive component 51, the baffle drive component 53, and the intermediate drive component 52 can transmit power to each other, for example, through friction, through fluid, or through meshing. This application does not specifically limit the method by which the main brush drive component 51, the baffle drive component 53, and the intermediate drive component 52 transmit power to each other. Any transmission method that allows the main brush drive component 51 and the baffle drive component 53 to rotate in opposite directions via the intermediate drive component 52 is within the scope of protection of this application.

[0107] In some embodiments of this application, such as Figures 4 to 6 As shown, the main brush drive component 51 includes a main brush drive gear 511. The intermediate drive component 52 includes an intermediate drive gear set 520. The baffle drive component 53 includes a baffle drive gear 531. The main brush drive gear 511, the intermediate drive gear set 520, and the baffle drive gear 531 mesh.

[0108] Therefore, the main brush drive component 51, the baffle drive component 53, and the intermediate drive component 52 can transmit circumferential power through gear meshing. During gear transmission, the tooth surfaces of each gear can mesh through surface contact, resulting in relatively low energy loss and high transmission efficiency. Moreover, gear transmission has accurate transmission ratios, strong load-bearing capacity, and long service life, which helps to reduce the production and replacement costs of parts while stably transmitting power.

[0109] Specifically, such as Figure 6 As shown, the intermediate transmission gear set 520 includes a first gear 521, a second gear 522, and a third gear 523. The first gear 521 meshes with the main brush transmission gear 511. The second gear 522 is coaxially arranged with the first gear 521. The third gear 523 meshes with the second gear 522 and also meshes with the baffle transmission gear 531.

[0110] When the main brush drive gear 511 rotates under the drive of the main brush 2 or the first drive mechanism 4, it drives the first gear 521 to rotate in the opposite direction to the rotation of the main brush drive gear 511. The first gear 521 drives the coaxially arranged second gear 522 to rotate in the same direction. The second gear 522 drives the third gear 523 to rotate in the opposite direction to the rotation of the second gear 522. The third gear 523 drives the baffle drive gear 531 to rotate in the opposite direction to the rotation of the third gear 523. Thus, the main brush drive gear 511 and the baffle drive gear 531 can rotate in opposite directions through the intermediate drive gear set 520, thereby enabling the main brush 2 and the baffle 3 to rotate in opposite directions.

[0111] Of course, those skilled in the art should understand that the intermediate transmission gear set 520 may not only include the three gears mentioned above. In some other embodiments, the intermediate transmission gear set 520 may include more or fewer gears. This application does not specifically limit this, and the design can be based on the actual required transmission ratio. The key is to ensure that the main brush drive gear 511 and the baffle drive gear 531 can rotate in opposite directions via the intermediate transmission gear set 520, and to meet the transmission ratio requirements.

[0112] In this embodiment, although the baffle 3 can rotate between a first position and a second position, it does not rotate continuously like the main brush 2 during the operation of the cleaning device. That is, when the baffle 3 moves to the first or second position, it stops rotating. Meanwhile, the main brush 2 continues to rotate. Therefore, a clutch is needed to disconnect the baffle 3 from the main brush 2 when it rotates to the first or second position. In other words, the clutch prevents the baffle 3 from rotating with the main brush 2 when it reaches the first or second position.

[0113] like Figure 6 As shown, the first gear 521 is provided with a first clutch portion. The second gear 522 is provided with a second clutch portion 5221. The first clutch portion and the second clutch portion 5221 are arranged opposite to each other. When the first clutch portion and the second clutch portion 5221 are connected, the second gear 522 and the first gear 521 are circumferentially connected. When the first clutch portion and the second clutch portion 5221 are disengaged, the second gear 522 and the first gear 521 are no longer circumferentially connected.

[0114] Therefore, when the baffle 3 moves to the first or second position, the first clutch part disengages from the second clutch part 5221, thereby disengaging the coaxially arranged second gear 522 from the first gear 521 and preventing the baffle 3 from rotating with the main brush 2. Conversely, when the baffle 3 needs to rotate from the first position to the second position, or vice versa, the first engagement part engages with the second clutch part 5221, causing the second gear 522 to circumferentially engage with the first gear 521. This allows the second gear 522 to rotate along with the first gear 521, thus enabling the baffle 3 to rotate along with the main brush 2.

[0115] Those skilled in the art will understand that although the first clutch portion is not shown in the figure, the first clutch portion and the second clutch portion have the same structure. The terms "first" and "second" are used here only to better distinguish the clutch portion provided on the first gear 521 and the clutch portion provided on the second gear 522.

[0116] In some embodiments of this application, such as Figure 6 As shown, the first clutch portion includes a first protrusion located on the side of the first gear 521 facing the second gear 522. The second clutch portion 5221 includes a second protrusion located on the side of the second gear 522 facing the first gear 521.

[0117] When the baffle 3 is located between the first and second positions, the sidewall of the first protrusion abuts against the sidewall of the second protrusion. That is, the sidewall of the first protrusion abuts against the sidewall of the second protrusion. This allows the first protrusion to push the second protrusion to move together, so that the second gear 522 can rotate together with the first gear 521.

[0118] When the baffle 3 reaches the first or second position, it can no longer move because it has reached its limit. At this time, the first protrusion and the second protrusion slide under the action of the driving force, causing the first protrusion to disengage from the second protrusion. This prevents the second protrusion from being pushed by the first protrusion, and consequently prevents the second gear 522 from rotating with the first gear 521, causing the baffle 3 to remain in the first or second position.

[0119] There can be multiple first protrusions and multiple second protrusions. The number of first protrusions and second protrusions is the same, and they are arranged alternately. This allows the first gear 521 to rotate by abutting the sidewalls of the first and second protrusions, thereby driving the second gear 522 to rotate. This application does not specifically limit the number of first and second protrusions in the embodiments.

[0120] In the embodiments of this application, such as Figure 6As shown, the sidewalls of both the first and second protrusions are inclined. That is, the cross-sectional size of the first protrusion gradually decreases from the gear surface of the first gear 521 towards the direction facing the second gear. Similarly, the cross-sectional size of the second protrusion gradually decreases from the gear surface of the second gear 522 towards the direction facing the first gear. This results in both the first and second protrusions being approximately trapezoidal in shape. The inclined sidewalls facilitate easier disengagement of the first and second clutch parts when needed. Consequently, after the baffle 3 reaches the first or second position, the first and second clutch parts can more easily disengage from each other due to the inclined sidewalls.

[0121] In some embodiments, only the sidewall of the first protrusion may be inclined, or only the sidewall of the second protrusion may be inclined, or both the sides of the first and second protrusions may be planar. This application does not specifically limit the shape of the sidewall of the first or second protrusion; any solution where the first and second protrusions can disengage when the baffle 3 reaches the first or second position is within the scope of protection of this application.

[0122] In some embodiments, the first protrusion and / or the second protrusion may also be made of a material with a certain deformation capability, so that when the baffle 3 reaches the first position or the second position, the first protrusion and / or the second protrusion deform under the action of the driving force, causing the first protrusion and the second protrusion to slide and thus separate.

[0123] The first clutch portion and the second clutch portion 5221 can also be in other forms, such as partially distributed teeth. When the baffle 3 is located between the first position and the second position, the first clutch portion and the second clutch portion 5221 are engaged. When the baffle 3 is located in the first position or the second position, the first clutch portion and the second clutch portion 5221 are no longer engaged.

[0124] In some embodiments of this application, such as Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the main brush housing 1 includes a first limiting part 11. When the baffle 3 is in the second position, it abuts against the first limiting part 11. The main brush housing 1 includes a second limiting part 12. When the baffle 3 is in the first position, it abuts against the second limiting part 12.

[0125] Therefore, when the baffle 3 reaches the first or second position, it can abut against the first limiting part 11 and the second limiting part 12, thus remaining in its current position and no longer rotating with the main brush 2. When the baffle 3 is limited by the first limiting part 11 or the second limiting part 12, the first clutch part and the second clutch part 5221 disengage from each other, so that the second gear 522 of the intermediate transmission gear set 520 no longer rotates with the first gear 521.

[0126] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, along the travel direction X, the first limiting part 11 is located in front of the main brush 2. And along the height direction of the roller brush assembly 100, the first limiting part 11 is located above the baffle 3. The baffle 3 includes a main body 31. In the second position, at least a portion of the surface of the main body 31 facing the main brush housing 1 is in contact with the surface of the first limiting part 11.

[0127] The main body 31 refers to the part of the baffle 3 that performs the shielding function. When the baffle 3 is in the first position, viewed along the travel direction X, the main body 31 at least partially shields the main brush 2, thereby allowing the main body 31 to intercept the dust stirred up by the reverse rotation of the main brush 2, reducing the possibility of secondary pollution. When the baffle 3 is in the second position, the main body 31 rotates away from the main brush 2, thereby exposing part of the main brush 2, which facilitates better cleaning of the first working surface when the main brush 2 rotates in the forward direction.

[0128] The first limiting part 11 includes a flat surface. When the baffle 3 is in the second position, a portion of the surface of the main body 31 is in surface contact with the flat surface of the first limiting part 11 for limiting. When the first limiting part 11 limits the baffle 3, the contact area is larger due to the abutting connection of two surfaces, thus achieving a more reliable limiting effect and reducing the risk of the baffle 3 continuing to rotate after reaching the second position. Furthermore, surface contact reduces the possibility of stress concentration, thereby reducing the likelihood of damage to the first limiting part 11 or the baffle 3 during the limiting process.

[0129] Of course, those skilled in the art should understand that in some other embodiments, line connection limiting, point connection limiting, snap-fit ​​connection limiting, etc., can also be used to limit the baffle 3 at the second position. Any solution that allows the baffle 3 to stop rotating when it moves to the second position is within the protection scope of this application.

[0130] In some embodiments of this application, such as Figure 7 and Figure 8 As shown, the baffle 3 also includes a stop portion 32. The stop portion 32 is located on at least one side of the main body portion 31 along its length direction. The second limiting portion 12 is located on at least one side of the first limiting portion 11 along its length direction and corresponds to the side where the stop portion 32 is located. The baffle 3 is in a first position, and a portion of the surface of the stop portion 32 is in contact with the surface of the second limiting portion 12.

[0131] The stop portion 32 is generally semi-circular and can rotate together with the main body 31. The peripheral surface of the semi-circular stop portion 32 includes a flat portion and a curved portion. When the baffle 3 rotates between the first position and the second position, the curved portion of the stop portion 32 can rotate relative to the first limiting portion 11. When the baffle 3 is in the second position, a portion of the surface of the main body 31 abuts against the first limiting portion 11 for limitation. At this time, the flat portion of the stop portion 32 does not interfere with the second limiting portion 12. When the baffle 3 is in the first position, the flat portion of the stop portion 32 contacts the surface of the second limiting portion 12, thereby limiting the baffle 3 and allowing the baffle 3 to remain in the first position.

[0132] like Figure 8 As shown, the second limiting portion 12 is generally L-shaped. Specifically, at least a portion of the second limiting portion 12 extends toward the main brush 2, forming an extension portion. When the baffle 3 is in the first position, the flat portion of the stop portion 32 makes surface contact with the extension portion of the second limiting portion 12. This surface contact method facilitates a more reliable limiting effect and can improve the service life of the second limiting portion 12 and the stop portion 32.

[0133] Of course, those skilled in the art will understand that in some other embodiments, any other suitable method can be used to limit the baffle 3 at the first position. Any solution that allows the baffle 3 to stop rotating when it moves to the first position is within the scope of protection of this application.

[0134] In the embodiment of this application, there are two second limiting portions 12. The two second limiting portions 12 are located on opposite sides of the first limiting portion 11 along its length direction. There are also two stop portions 32. The two stop portions 32 are located on opposite sides of the main body portion 31 along its length direction. By the limiting cooperation between the two stop portions 32 and the two second limiting portions 12, the baffle 3 can further increase the limiting effect on the baffle 3 in the first position and improve the limiting reliability.

[0135] Of course, in some other embodiments, only a second limiting part 12 and a stop part 32 may be provided.

[0136] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the first limiting part 11 has a groove 111. The baffle 3 also includes a protrusion 33. The baffle 3 is in the second position, and the protrusion 33 is embedded in the groove 111.

[0137] A portion of the surface of the main body 31 protrudes away from the main brush 2 to form a protrusion 33. The first limiting portion 11 is recessed away from the baffle 3 to form a groove 111. The shape of the groove 111 corresponds to the shape of the protrusion 33, so that when the baffle 3 is in the second position, the protrusion 33 can be inserted into the groove 111. Thus, the contact area between the baffle 3 and the first limiting portion 11 is further increased by the cooperation between the protrusion 33 and the groove 111, thereby playing a certain role in preventing mistaken identity. This reduces the possibility of the baffle 3 continuing to rotate after reaching the second position, which could lead to excessive deformation of the baffle 3, and improves the service life of the baffle 3.

[0138] In some embodiments of this application, such as Figure 9 As shown, the roller brush assembly 100 includes a second drive mechanism 6 and a third drive mechanism 7. The second drive mechanism 6 is located in the main brush housing 1 and is circumferentially connected to the main brush 2. The third drive mechanism 7 is located in the main brush housing 1 and is circumferentially connected to the baffle 3.

[0139] Therefore, the main brush 2 and the baffle 3 can be driven separately by different drive mechanisms, resulting in a simpler structure and better controllability.

[0140] For example, the second drive mechanism 6 can be directly connected to the main brush 2 in a circumferential drive configuration. The third drive mechanism 7 can be directly connected to the baffle 3 in a circumferential drive configuration.

[0141] As another example, the second drive mechanism 6 can be circumferentially driven connected to the second transmission mechanism 8, and the second transmission mechanism 8 is circumferentially driven connected to the main brush 2. The third drive mechanism 7 can be circumferentially driven connected to the third transmission mechanism 9, and the third transmission mechanism 9 is circumferentially driven connected to the baffle 3.

[0142] This application does not limit the transmission connection relationship between the second drive mechanism 6 and the third drive mechanism 7 and the main brush 2 and the baffle 3, respectively. Any connection method that enables the second drive mechanism 6 and the third drive mechanism 7 to drive the main brush 2 and the baffle 3 to rotate is within the protection scope of this application.

[0143] As a specific example, the second transmission mechanism 8 and the third transmission mechanism 9 can be gear transmission mechanisms.

[0144] In some embodiments of this application, although not shown in the figures, the cleaning device also includes a controller and a detection component. The controller is located in the main body and is used to detect the type of the working surface. Both the detection component and the roller brush assembly 100 are communicatively connected to the controller, which controls the rotation direction of the main brush 2 of the roller brush assembly 100 and the position of the baffle 3 based on the type of the working surface detected by the detection component.

[0145] The detection component and the roller brush assembly 100 are communicatively connected to the controller. The detection component can transmit the detected type information of the working surface to the controller in a timely manner. Based on the detected type information of the working surface, the controller controls the rotation direction of the main brush 2 and the position of the baffle 3 of the roller brush assembly 100.

[0146] Therefore, the type of working surface can be detected automatically through the controller and detection components. Furthermore, based on the detected type of working surface, the rotation direction of the main brush 2 and the position of the baffle 3 can be controlled automatically, resulting in higher automation and better reliability.

[0147] For example, the detection component and the roller brush assembly 100 can be electrically connected to the controller, connected via Bluetooth, connected via antenna signal, or connected via WiFi, etc. This application does not specifically limit the connection method between the detection component, the roller brush assembly 100, and the controller; any connection method that enables information transmission is within the scope of protection of this application.

[0148] In some embodiments of this application, the detection component includes at least one of a visual recognition component, an ultrasonic sensor, or an optical sensor.

[0149] Of course, those skilled in the art should understand that in some other embodiments, the detection component can also be any other suitable detection component, as long as the detection component can detect the type of working surface, it is within the protection scope of this application.

[0150] In some embodiments of this application, such as Figure 10 As shown, the main brush housing 1 has a receiving cavity 10 with an opening 13. The main brush 2 is disposed within the receiving cavity 10 and contacts the working surface through the opening 13. The cleaning device also includes a dust box 300 and an air duct 200. The dust box 300 has a receiving cavity 20 inside, and the air duct 200 connects the receiving cavity 10 and the receiving cavity 20. A portion of the air duct 200 is located on the side of the main brush 2 facing away from the opening 13.

[0151] The main brush 2 is housed within the receiving cavity 10 with an opening 13, and contacts the work surface through the opening 13. This structure allows the main brush 2 to more flexibly conform to the work surface for cleaning. For work surfaces of different shapes and textures, the main brush 2 can make close contact with them at the opening 13, thereby more effectively removing dust, stains, etc., and achieving a more comprehensive cleaning.

[0152] Part of the air duct 200 is located on the side of the main brush 2 facing away from the opening 13. Specifically, the air inlet of the air duct 200 is located on the side of the main brush 2 facing away from the opening. When the main brush 2 rotates forward, it passes through the working surface from front to back. Thus, the debris carried by the forward rotation of the main brush 2 enters the receiving cavity 10 from the rear of the opening 13, and then enters the dust box 300 through the air duct 200. When the main brush 2 rotates in the reverse direction, it passes through the working surface from back to front. Thus, the debris carried by the reverse rotation of the main brush 2 enters the receiving cavity 10 from the front of the opening 13, and then enters the dust box 300 through the air duct 200. In this embodiment, the air inlet position of the air duct 200 is moderate, so that whether the main brush 2 rotates forward or in the reverse direction, the path length required for dust, debris, etc., to enter the air duct 200 from the front or rear of the opening 13 is approximately the same, thereby simultaneously accommodating the debris collection of the main brush 2 during both forward and reverse rotation, which is beneficial to improving the cleaning effect.

[0153] In some embodiments of this application, such as Figure 11 As shown, the main brush housing 1 also has an air outlet 14. The air outlet 14 connects the receiving cavity 10 and the air duct 200. When the main brush 2 is in contact with the working surface, the angle θ between the location of the air outlet 14 and the working surface in a plane perpendicular to the axis of the main brush 2 is between 60° and 135°.

[0154] The air outlet 14 is positioned at a certain angle to the working surface. When the main brush 2 rotates and stirs up the dust, it can better guide the dust from the working surface upwards to the air duct 200. This allows the dust to smoothly enter the air duct 200 along the direction of the air outlet 14 and be sucked into the dust box 300, reducing the escape of dust in the receiving cavity 10 and improving the efficiency of dust collection.

[0155] In addition, the angle between the air outlet 14 and the working surface is set within a suitable range, which helps to form a more reasonable airflow field, allowing dust to flow orderly towards the air outlet 14 and the air duct 200 within the receiving cavity 10. This reduces disorderly collision and deposition of dust within the receiving cavity 10, thereby further improving the dust capture and collection capabilities of the cleaning equipment. Especially for some lighter, easily airborne dust, it can be better sucked into the dust box 300.

[0156] For example, the angle θ between the location of the air outlet 14 and the working surface can be 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130° or 135°, etc.

[0157] This application also provides a method for controlling cleaning equipment. For example... Figure 12 As shown, the control methods include:

[0158] S100: Obtain information about the type of working surface of the cleaning equipment.

[0159] For example, the cleaning equipment can acquire the type information of the working surface through a detection component set in the main body. The type information of the working surface includes, but is not limited to, image information, echo reflection information, optical reflection information, etc.

[0160] S200: Based on the type information of the working surface, control the rotation direction of the main brush 2 of the roller brush assembly 100 of the cleaning equipment.

[0161] Therefore, the cleaning equipment can control the rotation direction of the main brush 2 according to different working surface types, so that the cleaning equipment can have a good cleaning effect on different working surfaces.

[0162] In some embodiments of this application, such as Figure 13 As shown, the type information of the working surface for the cleaning equipment includes:

[0163] S101: Obtain image information of the working surface and determine the type information of the working surface based on the image information.

[0164] For example, the cleaning equipment may include a vision recognition component. The vision recognition component is used to acquire image information of the work surface. If the image information acquired by the vision recognition component satisfies a first preset image, the work surface is determined to be a first work surface. If the image information acquired by the vision recognition component satisfies a second preset image, the work surface is determined to be a second work surface.

[0165] Visual recognition components include, but are not limited to, cameras.

[0166] S102: Obtain the echo signal reflected from the working surface and determine the type information of the working surface based on the echo signal.

[0167] For example, the cleaning equipment includes an ultrasonic sensor. The ultrasonic sensor is used to send ultrasonic signals to the working surface. The controller controls the ultrasonic sensor to send ultrasonic signals to the working surface and receives the actual echo signals reflected from the current working surface. The controller compares the actual echo signals with standard echo signals to identify the working surface as a first working surface or a second working surface.

[0168] S103: Obtain optical information of the working surface and determine the type information of the working surface based on the optical information.

[0169] For example, the cleaning equipment includes an optical sensor. A controller controls the optics to emit a first light beam toward the working surface and receives a second light beam reflected from the current working surface. If the intensity of the second light beam is greater than a preset intensity, the working surface is determined to be a first working surface. If the intensity of the second light beam is less than the preset intensity, the working surface is determined to be a second working surface.

[0170] In some embodiments of this application, such as Figure 14 As shown, based on the type information of the working surface, the rotation direction of the main brush 2 of the roller brush assembly 100 of the cleaning equipment is controlled as follows:

[0171] S201: When the working surface is obtained as the first working surface, control the main brush 2 to pass through the first working surface from front to back along the X direction of travel.

[0172] S202: When the working surface is determined to be the second working surface, control the main brush 2 to pass through the second working surface from back to front along the X direction of travel.

[0173] The first working surface includes a hard working surface, and the second working surface includes a carpet.

[0174] Therefore, when the cleaning equipment is working on a hard surface, the main brush 2 can be controlled to move from front to back along the travel direction X. And when the cleaning equipment is working on a carpet, the main brush 2 can be controlled to move from back to front along the travel direction X. This ensures that the cleaning equipment can achieve good cleaning results when cleaning different surfaces, improving the user experience.

[0175] In some embodiments of this application, such as Figure 15 As shown, the control method also includes:

[0176] S300: Based on the type information of the working surface, control the position of the baffle 3 of the roller brush assembly 100 of the cleaning equipment.

[0177] Therefore, the baffle 3 can reduce the secondary diffusion of dust and garbage in the air, thereby further improving the cleaning effect of the cleaning equipment.

[0178] In some embodiments of this application, such as Figure 16 As shown, based on the type information of the working surface, the position of the baffle 3 of the roller brush assembly 100 of the cleaning equipment is controlled as follows:

[0179] S301: When the working surface is determined to be the first working surface, control the baffle 3 to move to the second position.

[0180] S302: When the working surface is determined to be the second working surface, control the baffle 3 to move to the first position.

[0181] Specifically, when the baffle 3 is in the first position, the area obstructed by the main brush 2 is greater than the area obstructed by the baffle 3 when it is in the second position. The first working surface includes a hard working surface. The second working surface includes a carpet.

[0182] Therefore, when the cleaning equipment is working on a hard surface, the baffle 3 is in the second position. This prevents interference with the main brush 2 when it rotates forward, allowing the main brush 2 to clean the hard surface more effectively. When the cleaning equipment is working on a carpet, the baffle 3 is in the first position. This allows the baffle 3 to block dust and debris raised when the main brush 2 rotates in the reverse direction, improving the cleaning effect on the carpet while reducing the risk of secondary diffusion of dust and debris.

[0183] Of course, those skilled in the art will understand that a second working surface is not limited to carpets. In some embodiments, simulated lawns, woven mats, blankets, etc., may also be considered a second working surface.

[0185] This application also provides a controller. For example... Figure 17 As shown, the controller 400 includes a processor 401 and a memory 402. The memory 402 stores machine-readable instructions 4021 that can be executed by the processor 401. When the controller 400 is running, the machine-readable instructions 4021 are executed by the processor 401 to perform the control method of the cleaning device of this application.

It should be understood that bus system 403 is used to implement communication connections between these components. In addition to a data bus, bus system 403 also includes a power bus, a control bus, and a status signal bus, etc. However, for clarity, in...

[0189] This application also provides a computer-readable storage medium. A computer program is stored on the computer-readable storage medium. When the computer program is run by a processor, it executes the control method for the cleaning device of this application.

[0190] It should be noted that the storage medium in the embodiments of this application can be implemented by any type of volatile or non-volatile storage device, or a combination thereof.

[0194] As a concrete example, the main brush module (roller brush assembly 100) of the sweeper (cleaning equipment) includes a main brush 2. The main brush 2 rotates clockwise, sweeping the ground (working surface) from front to back in the forward direction (travel direction X). The main brush 2 rotates counter-clockwise, sweeping the ground from back to front in the forward direction. Compared to counter-clockwise rotation, clockwise rotation of the main brush 2 prevents dust from being thrown around and is prevented from being hit in front of the sweeper. When the main brush 2 rotates clockwise, dust is carried to the rear of the main brush by its rotation and sucked into the suction port (air outlet 14). When the main brush 2 rotates counter-clockwise, dust is carried to the front of the main brush. A controllable baffle 3 is designed in front of the main brush module. The purpose of the baffle 3 is to lower when the main brush 2 rotates counter-clockwise, forming a complete air duct, facilitating the main brush 1 to sweep debris into the dustbin 300. The baffle control mechanism (baffle transmission component 53) and the main brush gearbox (main brush transmission component 51) are driven by the same motor (first drive mechanism 4). When the main brush 2 rotates forward, the baffle 3 retracts (in the second position), and when the main brush 2 rotates in reverse, the baffle is lowered (in the first position).

[0195] The main brush module also includes an intermediate transmission gear set 520 connected to the baffle control mechanism and the main brush gearbox. The intermediate transmission gear set 520 includes a first gear 521 and a second gear 522. The opposing sides of the first gear 521 and the second gear 522 are respectively designed with raised ribs (first clutch portion, second clutch portion 5221). Torque is transmitted between the first gear 521 and the second gear 522 through the raised ribs. When the first gear 521 rotates forward, it abuts against the raised rib of the second gear 522, thereby pushing the second gear 522 to rotate forward. The second gear 522 transmits torque to the baffle 3, thereby causing the baffle to rotate and lift. When the baffle 3 rotates to its limit position, the raised ribs will slip. At this time, the main brush 2 continues to rotate forward, but the baffle 3 no longer rotates. When the first gear 521 rotates in reverse, it abuts against the raised rib of the second gear 522, thereby pushing the second gear 522 to rotate in reverse. The second gear 522 transmits torque to the baffle 3, thereby causing the baffle 3 to rotate and descend. When baffle 3 rotates to its limit, the raised ribs will slip. At this point, main brush 2 continues to reverse, but baffle 3 stops rotating.

[0196] The air duct of the main brush module is designed to be located directly above the main brush module. This design allows for the collection of waste whether the main brush is rotating forward or backward.
