[0063] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0064] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0065] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0066] like Figures 1 to 6 As shown, this disclosure first provides a cleaning device, which may include a carrier device and a cleaning device. The cleaning device may be a robotic vacuum cleaner, a floor scrubber, a vacuum cleaner, a combined sweeper and mop, a window cleaning robot, etc. The cleaning device may include a cleaning unit, which may be a roller brush, a side brush, a water outlet, a mopping component, a window cleaning component, etc., for cleaning the surface to be cleaned.

[0067] like Figure 1 As shown, the supporting device may include: a main body 1 and a rotating mechanism 2. Wherein, as... Figure 2 As shown, the main body 1 may be provided with a receiving cavity 11 and a first cleaning through hole 12. The receiving cavity 11 can accommodate the cleaning device, and the first cleaning through hole 12 can expose the cleaning part of the cleaning device. The main body 1 may also be provided with a walking assembly for movement and climbing. It is understood that climbing mentioned in this application includes moving from a lower surface to a higher surface and / or moving from a higher surface to a lower surface.

[0068] The rotating mechanism 2 can be installed on the main body 1, and at least a portion of the rotating mechanism 2 can be located within the receiving cavity 11, or at least a portion of the rotating mechanism 2 can be located within the first cleaning through hole 12, or at least a portion of the rotating mechanism 2 can be located simultaneously within the receiving cavity 11 and the first cleaning through hole 12, and at least a portion of the rotating mechanism 2 can contact the cleaning device. The rotating mechanism 2 can be configured to drive the cleaning device to rotate relative to the main body 1 in a first direction X or in a direction opposite to the first direction X, where the first direction X can be the direction surrounding the central axis of the first cleaning through hole 12. That is, it can be understood that the rotating mechanism 2 can drive the cleaning device to rotate relative to the main body 1 in a first direction X or in a direction opposite to the first direction X through the portion that contacts the cleaning device. The first direction X can be clockwise, and the direction opposite to the first direction X can be counterclockwise; or, the first direction X can be counterclockwise, and the direction opposite to the first direction X can be clockwise.

[0069] It should be noted that the "contact" mentioned above should be understood as: the surfaces of two structures are in contact with each other, or there is a connection between the two structures, or the two structures abut against each other, or the two structures are engaged with each other, or the two structures are locked together, etc.

[0070] In the cleaning apparatus, the cleaning device can be located within the receiving cavity 11 and can contact the rotating mechanism 2. The cleaning part of the cleaning device can be exposed through the first cleaning through hole 12 of the main body 1, so as to clean the surface to be cleaned using the exposed cleaning part.

[0071] The carrier device provided in this disclosure is equipped with a receiving cavity 11 capable of accommodating cleaning equipment. This allows the cleaning equipment to be transported to different floors, enabling it to clean various surfaces and increasing its cleaning range. Simultaneously, the main body 1 is also provided with a first cleaning through-hole 12 that exposes the cleaning part of the cleaning equipment. This allows the cleaning equipment to continue cleaning surfaces such as steps and railings within the receiving cavity 11 while the carrier device is moving and climbing, further expanding its cleaning range. Furthermore, the cleaning equipment can complete the cleaning work without leaving the receiving cavity 11, saving time and steps associated with leaving and re-entering the carrier device, thereby improving cleaning efficiency and the climbing efficiency of the carrier device.

[0072] Secondly, by incorporating a rotating mechanism 2 within the carrier device, the cleaning equipment can be rotated within the housing cavity 11 of the carrier device. Therefore, when the cleaning equipment is cleaning the surface to be cleaned, rotating the cleaning equipment via the rotating mechanism 2 further increases the cleaning range, thereby improving the cleaning effect.

[0073] In some embodiments, such as Figure 3 As shown, the rotating mechanism 2 may include a tray 21. The tray 21 is rotatably mounted within the first cleaning through-hole 12 and is configured to support the cleaning equipment. This arrangement allows the second tray 21 to support the cleaning equipment, increasing its support and preventing it from falling. Simultaneously, the tray 21 also protects the bottom surface of the cleaning equipment, preventing damage from hard objects on the surface to be cleaned.

[0074] The tray 21 may be provided with a second cleaning through-hole 211, through which the cleaning part of the cleaning equipment is exposed. For example, the second cleaning through-hole 211 may expose the bristles of the roller brush or side brush of the cleaning equipment. This arrangement can prevent the tray 21 from obstructing the cleaning part, thereby ensuring the cleaning effect of the cleaning equipment located in the carrier equipment.

[0075] Furthermore, when the cleaning device includes multiple cleaning parts, the second cleaning through-hole 211 can be divided into multiple sub-through-holes, each of which can expose one type of cleaning part. For example, when the cleaning device includes a roller brush and a side brush, the second cleaning through-hole 211 can be divided into two sub-through-holes: a first sub-through-hole 2111 and a second sub-through-hole 2112. The first sub-through-hole 2111 can be used to expose the roller brush, and the second sub-through-hole 2112 can be used to expose the bristles of the side brush, etc. This arrangement allows for the use of spaced sub-through-holes to expose the corresponding cleaning parts when the cleaning device includes multiple cleaning parts, avoiding the need to use a single second cleaning through-hole 211 with a large opening area to expose all cleaning parts. Therefore, the opening area of ​​the second through hole can be reduced, and the area ratio of the second cleaning through hole 211 on the tray 21 can be reduced, thereby providing a larger support area for the solid structure on the tray 21, which can improve the load-bearing capacity and structural strength of the tray 21, further prevent the cleaning equipment from falling off, and further prevent hard objects on the surface to be cleaned from damaging the cleaning equipment.

[0076] The rotating mechanism 2 may further include a drive unit 22. The drive unit 22 may be mounted on the main body 1 and contact the tray 21 for driving the tray 21 to rotate relative to the main body 1 in a first direction X or in a direction opposite to the first direction X.

[0077] The drive unit 22 may include a transmission member 221 and a drive member 222. The transmission member 221 may contact the tray 21 to drive the tray 21 to rotate. The drive member 222 may be connected to the transmission member 221 to drive the transmission member 221 to rotate relative to the main body 1 in a first direction X or in a direction opposite to the first direction X. This arrangement, by using the transmission member 221 to transmit the driving force provided by the drive member 222, improves the flexibility of the drive member 222's placement within the receiving cavity 11 and reduces the difficulty of arranging various components within the supporting equipment. The drive member 222 may be a drive motor, and the drive shaft of the drive motor may be connected to the transmission member 221 to output driving force to the transmission member 221.

[0078] In some embodiments, a portion of the outer peripheral surface of the transmission member 221 may contact a portion of the outer peripheral surface of the tray 21 to drive the tray 21 to rotate. The drive member 222 may be located on the end face side of the transmission member 221, and the drive member 222 may be connected to the end face of the transmission member 221. Because there are many components arranged in the length and / or width direction of the receiving cavity 11, the space for arranging components in the length and / or width direction of the receiving cavity 11 is relatively crowded. However, there are fewer components arranged in the height direction of the receiving cavity 11. In this embodiment, the drive member 222 is arranged on the end face side of the transmission member 221, which allows the drive member 222 and the transmission member 221 to be arranged in the height direction of the receiving cavity 11, thereby saving space in the length or width direction of the receiving cavity 11, reducing the length and / or width of the supporting device, and reducing the difficulty of arranging the various components in the supporting device.

[0079] In some embodiments, such as Figure 3 As shown, the tray 21 may include a supporting portion 212 and a first toothed portion 213. The supporting portion 212 can be used to support cleaning equipment, and a second cleaning through-hole 211 may be located in the supporting portion 212. The first toothed portion 213 may be disposed on at least a portion of the outer peripheral surface of the supporting portion 212. The first toothed portion 213 may include multiple teeth, and the spacing between any two adjacent teeth may be the same, but is not limited thereto.

[0080] At least a portion of the outer peripheral surface of the transmission member 221 may be provided with a second tooth 2211, and the first tooth 213 may mesh with the second tooth 2211, thereby realizing the transmission of force between the transmission member 221 and the tray 21, enabling the transmission member 221 to drive the tray 21 to rotate. Simultaneously, by providing the first tooth 213 and the second tooth 2211, the stability of the contact between the transmission member 221 and the tray 21 can be improved, ensuring that the transmission member 221 can stably transmit driving force to the tray 21, and improving the smoothness and continuity of the tray 21's rotation. The second tooth 2211 may also include multiple teeth, and the spacing between any two adjacent teeth may be the same, but is not limited to this.

[0081] In other embodiments, the tray 21 may not have the first tooth 213, and the transmission member 221 may not have the second tooth 2211. For example, the outer peripheral surface of the supporting part 212 and the outer peripheral surface of the transmission member 221 may be configured as surfaces with high friction. By contacting the two outer peripheral surfaces with high friction, the driving force can be transmitted through friction, which can also achieve the purpose of the transmission member 221 driving the tray 21 to rotate. Alternatively, a transmission belt or transmission chain may be sleeved on the outer peripheral surface of the supporting part 212 and the outer peripheral surface of the transmission member 221. The transmission member 221 can drive the transmission belt or transmission chain to move, so as to drive the supporting part 212 to rotate through the transmission belt or transmission chain. This can also achieve the purpose of the transmission member 221 driving the tray 21 to rotate, but it is not limited to this.

[0082] In some embodiments, such as Figure 3 As shown, the support portion 212 may further include a support ring 2121 and a support plate 2122. The first tooth 213 may be disposed on at least a portion of the outer peripheral surface of the support ring 2121.

[0083] The first tooth 213 and the bearing ring 2121 can be an integral structure, meaning they can be manufactured using a single process without the need for bonding, welding, riveting, or screw connections. This design reduces the number of connection points between the outer surfaces of the first tooth 213 and the bearing ring 2121, increasing the connection strength and thus improving the structural strength of the support 212. This further enhances the stability of the driving force transmission and extends the service life of the rotating mechanism 2 and the entire supporting device.

[0084] However, this is not the only option. The first tooth 213 and the bearing ring 2121 can also be separate structures, meaning that the first tooth 213 and the bearing ring 2121 can be manufactured separately and then connected as one unit by bonding, welding, riveting, screw connection, or other connection methods. This design can reduce the manufacturing difficulty of the first tooth 213 and the bearing ring 2121.

[0085] The support plate 2122 can be disposed on the side of the support ring 2121 away from the receiving cavity 11, and the support plate 2122 can be connected to the support ring 2121. The second cleaning through hole 211 can be located on the support plate 2122 so as to support the cleaning equipment using the support plate 2122.

[0086] like Figure 3 and Figure 4As shown, the projection of the support plate 2122 in the second direction Y can be located within the area enclosed by the projection of the support ring 2121 in the second direction Y, where the second direction Y can be the extension direction of the central axis of the support ring 2121. That is, it can be understood that the area of ​​the projection of the support plate 2122 in the second direction Y is smaller than the area enclosed by the projection of the support ring 2121 in the second direction Y. This arrangement ensures that the support plate 2122 has sufficient support force and structural strength while minimizing its area, thereby reducing the manufacturing cost of the support plate 2122. Simultaneously, this arrangement also avoids the problem of obstruction or positional interference to the moving parts of the cleaning equipment due to an excessively large area of ​​the support plate 2122.

[0087] In some embodiments, the bearing ring 2121 may also have a reinforcing plate, which may be disposed on a portion of the inner circumferential surface of the bearing ring 2121 to improve the structural strength of the bearing ring 2121. Simultaneously, the orthographic projection of the reinforcing plate in the second direction Y and the orthographic projection of the support plate 2122 in the second direction Y may overlap. The support plate 2122 may be connected to the reinforcing plate to achieve the purpose of connecting the support plate 2122 and the bearing ring 2121. This increases the connection area between the support plate 2122 and the bearing ring 2121, improves the connection strength between the support plate 2122 and the bearing ring 2121, and reduces the difficulty of connecting the support plate 2122 and the bearing ring 2121.

[0088] The support plate 2122 and the reinforcing plate can be connected by screws, which facilitates the disassembly and installation of the support plate 2122. When the support plate 2122 or the bearing ring 2121 is damaged, the support plate 2122 and the bearing ring 2121 can be separated, and only the damaged parts can be replaced, thereby reducing the maintenance cost of the bearing equipment. However, it is not limited to this; the support plate 2122 and the reinforcing plate can also be connected by bonding, welding, or other connection methods, which are also within the scope of protection of this disclosure.

[0089] In some embodiments, such as Figure 3 and Figure 4 As shown, the carrying device may further include a position detector 3. The position detector 3 can be installed on the main body 1 and located within the receiving cavity 11. The position detector 3 can be configured to detect the rotational position of the tray 21. With this configuration, the position detector 3 can accurately determine the rotational position of the tray 21 at this time, thereby accurately determining the rotational orientation of the cleaning equipment. The position detector 3 can be connected to the drive unit 22, and when the tray 21 is detected to rotate to a preset position, the tray 21 can stop rotating.

[0090] The carrier device may also include a controller, which may be a processor, but is not limited thereto. The controller may be located in the main body or the rotating mechanism, and the controller may be connected to the position detector 3. For example, the controller may be connected to the position detector 3 via a signal transmission line, or the controller may wirelessly connect to the position detector 3 via Bluetooth, wireless network, mobile network, or other communication methods.

[0091] The controller can be configured to stop the tray 21 from rotating when the position detector 3 detects that the tray 21 has rotated to a preset position. This setting allows for precise control of the rotation position of the tray 21, and also allows the position detector 3 and the controller to accurately control the orientation of the cleaning equipment. This avoids the cleaning equipment failing to rotate to the optimal cleaning angle due to excessive or insufficient rotation of the tray 21, thus ensuring the cleaning effect of the cleaning equipment on the surface to be cleaned.

[0092] The tray 21 may include at least one position mark 214, and the position detector 3 may be configured to detect the position of the position mark 214. When the position detector 3 detects that the position mark 214 has rotated to a preset position, the tray 21 stops rotating.

[0093] Furthermore, the controller can be configured to stop the tray 21 from rotating when the position detector 3 detects that the position mark 214 has rotated to a preset position. In this embodiment, by setting the position mark 214, the accuracy of the position detector 3 can be improved, which in turn can improve the accuracy of the rotation angle of the tray 21 and the cleaning equipment, thereby further improving the cleaning effect of the cleaning equipment on the surface to be cleaned.

[0094] like Figure 4 As shown, the tray 21 may include a first position mark 2141 and a second position mark 2142, which are spaced apart along the circumferential direction of the tray 21. When the position detector 3 detects the first position mark 2141, the controller can control the tray 21 to stop rotating, so that the cleaning device rotates to the first cleaning position to clean the surface to be cleaned. When the position detector 3 detects the second position mark 2142, the controller can control the tray 21 to stop rotating, so that the cleaning device rotates to the second cleaning position to clean the surface to be cleaned. With this configuration, by setting multiple position marks 214, the different rotation positions of the tray 21 can be accurately controlled according to cleaning needs, thereby accurately controlling the cleaning device's position and improving the cleaning effect.

[0095] The minimum included angle α between the first position mark 2141 and the second position mark 2142 can be greater than or equal to 10° and less than or equal to 180°. For example, the minimum included angle α between the first position mark 2141 and the second position mark 2142 can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 180°, etc. This setting ensures that the cleaning equipment can have a large cleaning range.

[0096] In some embodiments, the controller and the drive unit 22 can be connected in communication. For example, the controller can be connected in communication with the drive unit 22 through a signal transmission line, or the controller can be connected in communication with the drive unit 22 through Bluetooth, wireless network, mobile network or other communication methods to control the drive unit 22 to turn on or off.

[0097] When the position detector 3 detects that the position mark 214 has rotated to the preset position, the controller can control the drive unit 22 to stop applying driving force to the tray 21, thereby automatically controlling the tray 21 to stop rotating. That is, when the position detector 3 detects that the position mark 214 has rotated to the preset position, the controller can send a control signal to the drive unit 22. After receiving the control signal, the drive unit 22 can immediately stop working, thereby achieving the purpose of controlling the tray 21 to stop rotating.

[0098] Furthermore, when the tray 21 is equipped with a first tooth 213 and the transmission component 221 is equipped with a second tooth 2211, when the drive component 222 stops working, the transmission component 221 will immediately stop rotating. At this time, because the first tooth 213 and the second tooth 2211 are meshed, the second tooth 2211 on the transmission component 221 will immediately block the movement of the first tooth 213 on the tray 21, thereby immediately stopping the rotation of the tray 21. Therefore, when the tray 21 is equipped with a first tooth 213 and the transmission component 221 is equipped with a second tooth 2211, the rotation position of the tray 21 can be controlled more precisely, and thus the rotation direction of the cleaning equipment can be controlled more precisely.

[0099] The position detector 3 can be a photoelectric switch, and the position mark 214 can be a light-blocking plate or a reflector. The light-blocking plate can block the light, and the reflector can reflect the light emitted by the photoelectric switch.

[0100] When position marker 214 acts as a light-blocking plate, it will block external light. When the photoelectric switch cannot receive external light or the amount of light received by the photoelectric switch decreases, it can be determined that position marker 214 has rotated to a preset position. At this time, the controller can control the drive unit 22 to stop applying driving force to the tray 21.

[0101] When position marker 214 acts as a reflector, the light-blocking plate reflects the light emitted by the photoelectric switch. When the photoelectric switch receives the reflected light, it can be determined that position marker 214 has rotated to a preset position. At this time, the controller can control the drive unit 22 to stop applying driving force to the tray 21.

[0102] However, this is not the only possibility. The position detector 3 may not be a photoelectric switch; it may be other types of sensors, such as a vision sensor. The position mark 214 may not be a light-blocking plate or a reflector; it may be other types of position marks 214, such as position markers. The selection and setting can be made according to the actual situation, and all of this is within the scope of protection of this disclosure.

[0103] In some embodiments, such as Figure 3 and Figure 4 As shown, the position detector 3 can be set at a preset position of the rotation of the position mark 214 in order to improve the accuracy of the rotation position detection of the position mark 214.

[0104] In some embodiments, the position mark 214 may be disposed on the support ring 2121, thereby improving the integration of the tray 21. When the position mark 214 is a light-blocking plate or a reflector, the position mark 214 may be disposed on the end face of the support ring 2121.

[0105] The light-blocking plate or reflector and the supporting ring 2121 can be a single integrated structure. That is, the light-blocking plate or reflector and the supporting ring 2121 can be manufactured using an integrated process, without the need for bonding, welding, riveting, or screw connections. This design reduces the number of connection points between the light-blocking plate or reflector and the supporting ring 2121, thereby increasing the connection strength between them.

[0106] However, this is not the only option. The light-blocking plate or reflector and the supporting ring 2121 can also be separate structures. That is, the light-blocking plate or reflector and the supporting ring 2121 can be manufactured separately and then connected into one unit by bonding, welding, riveting, screw connection or other connection methods. This design can reduce the manufacturing difficulty of the light-blocking plate or reflector and the supporting ring 2121.

[0107] In some embodiments, the cleaning unit may include a side brush, and the second cleaning through-hole of the tray 21 may expose the bristles of the side brush of the cleaning device. The side brush may be configured to rotate the bristles during the cleaning process to clean the surface to be cleaned.

[0108] like Figure 4 and Figure 5As shown, the carrier device may further include a guide structure 4, which may be disposed on the main body 1 or the tray 21, and at least a portion of the guide structure 4 may be located on the side of the second cleaning through-hole away from the center of the main unit of the cleaning device, and on the rotation path of the bristles. The guide structure 4 may be configured to squeeze the bristles during the rotation of the side brush to guide the bristles to the surface to be cleaned, ensuring that the bristles are always in contact with the surface. This configuration allows the cleaning device to continue cleaning the surface using the side brush even when it is on the carrier device. This enables the cleaning device to simultaneously clean surfaces such as stairs and railings while the carrier device is moving or climbing. This further increases the cleaning range of the cleaning device, thereby improving the cleaning effect and the user experience.

[0109] In some embodiments, the rotation path of the bristles may include a first rotation path and a second rotation path. When the bristles rotate along the first rotation path, they gradually move away from the center of the cleaning device's main unit. When the bristles rotate along the second rotation path, they gradually move closer to the center of the cleaning device's main unit. It can be understood that the first and second rotation paths are each part of the bristle's rotation path, and the bristles need to rotate along both paths for one complete rotation.

[0110] The aforementioned guide structure 4 can be located on the first rotation path so that when the bristles rotate away from the center of the main unit of the cleaning device, the guide structure 4 can squeeze the bristles so that the bristles can sweep the dirt on the surface to be cleaned to the bottom of the cleaning main unit, thereby improving the cleaning effect.

[0111] The guide structure 4 may include a guide surface 42. The guide surface 42 may be located on the first rotation path, and the guide surface 42 may be configured to squeeze the bristles as the bristles rotate along the first rotation path to guide the bristles to the surface to be cleaned.

[0112] The guide surface 42 may have a first end and a second end. The distance between the first end of the guide surface 42 and the rotation axis of the bristles may be less than or equal to the rotation radius of the bristles, and the second end of the guide surface 42 is closer to the rotation axis of the bristles than the first end. During rotation, the bristles initially contact the guide surface 42 from the first end and separate from it from the second end. This arrangement ensures that the distance between the second end of the guide surface 42 and the rotation axis of the bristles is less than the rotation radius of the bristles, thereby ensuring that the guide surface 42 can continuously compress the bristles and improve its guiding effect.

[0113] The distance between the guide surface 42 and the rotation axis of the bristles can gradually decrease from the first end to the second end. This arrangement allows the guide surface 42 to gradually increase the amount of pressure applied to the bristles, enabling the bristles to gradually bend to the required bending angle, thus preventing damage to the bristles due to excessively rapid changes in bending angle.

[0114] Between the first end and the second end, the guide surface 42 can be an arc surface, which makes the change in the amount of pressure exerted by the guide surface 42 on the bristles smoother and improves the guiding effect of the guide surface 42 on the bristles. However, it is not limited to this; the guide surface 42 can also be a plane between the first end and the second end, which is also within the protection scope of this disclosure.

[0115] In some embodiments, the distance between the end of the guide surface 42 near the surface to be cleaned and the rotation axis of the bristles can be less than or equal to the rotation radius of the bristles. The end of the guide surface 42 away from the surface to be cleaned is closer to the rotation axis of the bristles than the end of the guide surface 42 near the cleaning surface. This arrangement allows the shape of the guide surface 42 to better match the setting angle of the bristles, further improving the smoothness of the guide surface 42 guiding the bristles.

[0116] The distance between the guide surface 42 and the rotation axis of the bristles gradually decreases from the end of the guide surface 42 away from the surface to be cleaned to the end of the guide surface 42 closer to the surface to be cleaned, so as to further match the setting angle of the bristles, thereby further improving the smoothness of the guide surface 42 in guiding the bristles and further improving the guiding effect.

[0117] Furthermore, between the end of the guide surface 42 furthest from the surface to be cleaned and the end of the guide surface 42 closest to the surface to be cleaned, the guide surface 42 can be a curved surface. This allows for a smoother change in the amount of pressure exerted by the guide surface 42 on the bristles, further improving the guiding effect of the guide surface 42 on the bristles. However, this is not a limitation; between the end of the guide surface 42 furthest from the surface to be cleaned and the end of the guide surface 42 closest to the surface to be cleaned, the guide surface 42 can also be a flat surface, which is also within the scope of protection of this disclosure.

[0118] In some embodiments, the distance between the end of the brush bristles closest to the surface to be cleaned and the surface to be cleaned can be less than the distance between the end of the guide surface 42 closest to the surface to be cleaned and the surface to be cleaned. This arrangement further ensures that the guide surface 42 can guide the side brush to the surface to be cleaned.

[0119] When the guide surface 42 is not pressing the bristles, the distance between the end of the bristle closest to the surface to be cleaned and the surface to be cleaned can be less than or equal to 2 cm. This setting further ensures that the guide surface 42 can guide the bristles to the surface to be cleaned.

[0120] In some embodiments, the distance between the end of the guide surface 42 away from the surface to be cleaned and the surface to be cleaned can be greater than the distance between most of the bristles and the surface to be cleaned, thereby providing a more stable guiding effect.

[0121] The guide structure 4 can be set on the bearing ring 2121, but is not limited thereto. The guide structure 4 can also be set on the support plate 2122, or the guide structure 4 can be set on both the bearing ring 2121 and the support plate 2122 at the same time, so as to provide a stable setting position for the guide structure 4.

[0122] Furthermore, the guide structure 4 can be disposed on the inner circumferential surface of the bearing ring 2121 so that the guide surface 42 is located on the rotation path of the bristles.

[0123] In some embodiments, the guide structure 4 can be a guide block 41, but it is not limited to this. The guide structure 4 can also be a guide plate or other structures, as long as the guide structure 4 has a guide surface.

[0124] In some embodiments, when the bristles are squeezed by the guide structure 4, the bending angle of the bristles can be greater than or equal to 10° and less than or equal to 120°. Examples include: 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, etc. This configuration ensures that the bristles can contact the surface to be cleaned after being squeezed.

[0125] In some embodiments, the carrier device may further include a guide structure 5. The guide structure 5 may have a guide surface 52, one end of which may be connected to a first end of a guide surface 42, and the distance between the end of the guide surface 52 away from the first end of the guide surface 42 and the rotation axis of the bristles may be greater than the rotation radius of the bristles.

[0126] In other words, since the distance between the first end of the guide surface 42 and the rotation axis of the bristles is less than or equal to the rotation radius of the bristles, the distance between the end of the guide surface 52 connected to the first end of the guide surface 42 and the rotation axis of the bristles can also be less than or equal to the rotation radius of the bristles. Since the distance between the end of the guide surface 52 away from the guide surface 42 and the rotation axis of the bristles can be greater than the rotation radius of the bristles, the guide surface 52 can smoothly receive the rotating bristles, guiding them smoothly to the first end of the guide plate. This provides better guidance and protection for the bristles.

[0127] Furthermore, the projection of the end of the guide surface 52 away from the guide surface 42 in the second direction Y can be located on the support plate 2122, so as to ensure that the distance between the end of the guide surface 52 away from the guide surface 42 and the rotation axis of the bristles can be greater than the rotation radius of the bristles.

[0128] The guide structure 5 can be connected to the guide structure 4 so that the guide surface 52 can be connected to the guide surface 42. The guide structure 5 can be a guide block 51, but is not limited to this. The guide structure 5 can also be a guide plate or other structures, as long as the guide structure 5 has a guide surface 52.

[0129] In some embodiments, the carrying device may further include a limiting structure 6, which may be disposed on the main body 1 or the tray 21. The limiting structure 6 may have a limiting surface 61, which is close to the rotation axis of the bristles relative to the wall of the second cleaning through hole 211, and one end of the limiting surface 61 may be connected to the second end of the guide surface 42. With this configuration, the limiting surface 61 can continuously squeeze the bristles after they have separated from the guide surface 42 to ensure the bending shape of the bristles, thereby ensuring that the bristles can still contact the surface to be cleaned after separating from the guide surface 42, thus improving the cleaning effect of the cleaning device.

[0130] In some embodiments, the end of the limiting surface 61 near the surface to be cleaned can be away from the surface to be cleaned relative to the end of the guide surface near the surface to be cleaned, so as to ensure the limiting effect of the limiting surface 61 on the bristles.

[0131] The limiting structure 6 can be set on the bearing ring 2121, but is not limited thereto. The limiting structure 6 can also be set on the support plate 2122, or the limiting structure 6 can be set on both the bearing ring 2121 and the support plate 2122 at the same time, so as to provide a stable setting position for the limiting structure 6.

[0132] Furthermore, the limiting structure 6 can be disposed on the inner circumferential surface of the bearing ring 2121 so that the limiting surface 61 is close to the rotation axis of the bristles relative to the hole wall of the second cleaning through hole 211.

[0133] In some embodiments, the limiting structure 6 can be a limiting block, but it is not limited to this. The limiting structure 6 can also be a limiting plate or other structures, as long as the limiting structure 6 has a limiting surface 61.

[0134] In some embodiments, the bearing ring 2121, guide structure 4, guide structure 5, and limiting structure 6 can be an integral structure, meaning that the bearing ring 2121, guide structure 4, guide structure 5, and limiting structure 6 can be manufactured using an integrated process, without the need for bonding, welding, riveting, screw connections, or other connection methods to integrate the various parts. This design reduces the number of connection points between the guide structure 4, limiting structure 6, and the inner circumferential surface of the bearing ring 2121, increasing the connection strength between them and reducing the probability of detachment, thereby extending their service life. Simultaneously, this design also reduces the number of connection points between the guide structure 4 and guide structure 5, increasing their connection strength and reducing the probability of separation.

[0135] However, this is not the only option. The load-bearing ring 2121, guide structure 4, guide structure 5, and load-bearing ring 2121 can also be separate structures. That is, the load-bearing ring 2121, guide structure 4, guide structure 5, and load-bearing ring 2121 can be manufactured separately and then connected into one unit by bonding, welding, riveting, screw connection, or other connection methods. This arrangement can reduce the manufacturing difficulty of the load-bearing ring 2121, guide structure 4, guide structure 5, and load-bearing ring 2121.

[0136] In some embodiments, such as Figure 6 As shown, the inner wall of the first cleaning through hole 12 may be provided with a first connecting portion 13, and the tray 21 may be provided with a second connecting portion 215. The tray 21 and the main body 1 can be slidably connected through the first connecting portion 13 and the second connecting portion 215, and the second connecting portion 215 can rotate relative to the first connecting portion 13, so that the tray 21 can rotate relative to the main body 1. By providing the first connecting portion 13 and the second connecting portion 215, the connection strength between the tray 21 and the main body 1 can be improved, and the stability of the tray 21 can be improved, reducing the probability of the tray 21 falling off.

[0137] The second connecting part 215 may be located on the supporting part 212 of the tray 21. For example, the first connecting part 13 may be provided on at least part of the outer peripheral surface of the carrying ring 2121 so that the carrying ring 2121 is slidably connected to the main body 1.

[0138] The first connecting part 13 can be a slider, and the second connecting part 215 can be a groove, with the slider extending into the groove and slidably connected to it. Alternatively, the first connecting part 13 can be a groove, and the second connecting part 215 can be a slider, with the slider extending into the groove and slidably connected to it. However, this is not a limitation; the first connecting part 13 and the second connecting part 215 may not be sliders and grooves, but other structures capable of slidable connection, such as pulleys. This disclosure does not specifically limit this, and the selection and setting can be made according to the actual situation, all of which are within the protection scope of this disclosure.

[0139] like Figures 7 to 9 As shown, some embodiments of this disclosure provide a control method for a carrier device, which can be used to control the carrier device described above.

[0140] It should be noted that the specific structure and beneficial effects of the carrier device have been described in detail in the above embodiments. Therefore, in this embodiment, the specific structure and beneficial effects of the carrier device will not be described again. Please refer to the specific description in the above embodiments, which are all within the protection scope of this disclosure.

[0141] like Figure 7 As shown, the control method for the carrier equipment may include:

[0142] Step S10: Obtain cleaning requirement information.

[0143] Step S20: Generate cleaning instructions based on cleaning requirement information. The cleaning instructions include rotation cleaning instructions.

[0144] Step S30: The controller responds to the rotation cleaning command and controls the rotation mechanism 2 to drive the cleaning equipment to rotate along the first direction X.

[0145] By controlling the carrier equipment using this control method, the cleaning range of the cleaning equipment can be increased, thereby further improving the cleaning effect.

[0146] In step S10, the cleaning requirement information includes: the location information of the carrier equipment, the dirt status information of the surface to be cleaned, etc. The location information of the carrier equipment may include whether the carrier equipment has climbed to a new location, etc.

[0147] In step S20, the position information of the carrier equipment can be identified; when the carrier equipment climbs to a new position, a rotation cleaning command can be generated.

[0148] In step S30, when the controller responds to the rotation cleaning command, the controller can control the drive unit 22 to work, so as to drive the tray 21 to rotate, thereby using the rotation of the tray 21 to drive the rotation of the cleaning equipment.

[0149] Furthermore, when the drive unit 22 includes a drive member 222 and a transmission member 221, the controller can control the drive member 222 to work so that the drive member 222 drives the transmission member 221 to rotate, and the transmission member 221 drives the tray 21 to rotate.

[0150] In some embodiments, the cleaning instructions described above may further include: a reset instruction. For example... Figure 8 As shown, the control method for the carrier equipment may further include:

[0151] Step S40: The controller responds to the reset command and controls the rotating mechanism 2 to rotate the cleaning equipment in the opposite direction to the first direction X. Thus, the controller can be used to return the cleaning equipment to its initial position for the next cleaning step.

[0152] In some embodiments, such as Figure 9 As shown, the control method for the carrier equipment may further include:

[0153] Step S50: Position detector 3 detects the rotational position of tray 21.

[0154] Step S60: When the position detector 3 detects that the tray 21 has rotated to the preset position, the controller controls the tray 21 to stop rotating.

[0155] Specifically, when the tray 21 includes at least one position mark 214, the position detector 3 can detect the position of the position mark 214; when the position detector 3 detects that the position mark 214 has rotated to a preset position, it can be considered that the tray 21 has rotated to the preset position, and at this time the controller can control the tray 21 to stop rotating.

[0156] For example, when the position detector 3 detects that the tray 21 has rotated to a preset position, the controller can send a control signal to the drive unit 22. After receiving the control signal, the drive unit 22 can immediately stop working, thereby achieving the purpose of controlling the tray 21 to stop rotating.

[0157] In some embodiments, such as Figure 10 As shown, prior to step S20, the control method for the carrier device may further include:

[0158] Step S70: Detect the position of the cleaning equipment.

[0159] Step S80: When the cleaning equipment is located in the receiving cavity 11, proceed with the following steps.

[0160] Furthermore, in step S80, if the cleaning device is not located within the receiving cavity 11, subsequent steps are stopped. This configuration prevents the rotating mechanism 2 from idling when the cleaning device is not within the receiving cavity 11, thereby saving energy consumption of the supporting equipment. Simultaneously, this configuration also prevents the rotating mechanism 2 from rotating before the cleaning device is fully inside the receiving cavity 11, thus avoiding damage to the cleaning device.

[0161] Furthermore, in step S80, when the cleaning equipment is not located within the receiving cavity 11, a reminder that the cleaning equipment is not in place can be issued. This reminder can be an audible alarm, a visual alarm, or a text message reminder, etc.

[0162] In some embodiments, a computer-readable storage medium is also provided, on which at least one piece of program code is stored, the at least one piece of program code being loadable and executed by a processor to implement the control method of the bearer device described in the above embodiments.

[0163] The computer program product may be a portable compact disc read-only storage medium (CD-ROM) and include at least one line of program code, and may run on a terminal device, such as a personal computer. However, the program product in this embodiment is not limited to this. In this embodiment, the computer-readable storage medium may be any tangible medium that contains or stores the computer program product, which may be used or used in conjunction with an instruction execution system, apparatus, or device.

[0164] Computer program products may be stored using one or more computer-readable storage media. Computer-readable storage media may be readable signal media or readable storage media. Readable storage media may be, for example, but not limited to, electrical, magnetic, optical, electromagnetic, infrared, or semiconductor systems, apparatuses, or devices, or any combination thereof. More specific examples of readable storage media (a non-exhaustive list) include: electrical connections having one or more wires, portable disks, hard disks, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or flash memory), optical fibers, portable compact disk read-only memory (CD-ROM), optical storage devices, magnetic storage devices, or any suitable combination thereof.

[0165] A readable signal medium may include a data signal propagated in baseband or as part of a carrier wave, carrying readable program code. This propagated data signal may take various forms, including but not limited to electromagnetic signals, optical signals, or any suitable combination thereof. A readable signal medium may also be any readable medium other than a readable storage medium, capable of sending, propagating, or transmitting a program for use by or in conjunction with an instruction execution system, apparatus, or device.

[0166] Program code contained on a computer-readable storage medium may be transmitted using any suitable medium, including but not limited to wireless, wired, optical fiber, RF, etc., or any suitable combination thereof.

[0167] Program code for performing the operations of this utility model can be written in any combination of one or more programming languages, including object-oriented programming languages.

[0168] In some embodiments, a bearer device is provided. The bearer device may include, but is not limited to, one or more processors and one or more memories. The one or more memories store at least one line of program code, which can be loaded and executed by the one or more processors to implement the various steps of the control method for the bearer device described in the above embodiments.

[0169] The memory may include readable media in the form of volatile memory, such as random access memory (RAM) and / or cache memory, and may further include read-only memory (ROM).

[0170] A cleaning system is also provided in some embodiments of this disclosure. For example... Figures 1 to 6 As shown, the cleaning system includes a base station and a cleaning device. The cleaning device can be the cleaning device described above, and the carrier device and / or the cleaning device itself can interface with the base station. The base station can charge and clean the carrier device, and / or charge, replenish water, and clean the cleaning device, or suck up dirt stored in the cleaning device.

[0171] It should be noted that the specific structure and beneficial effects of the cleaning device have been described in detail in the above embodiments. Therefore, in this embodiment, the specific structure and beneficial effects of the cleaning device will not be described again. Please refer to the specific description in the above embodiments, which are all within the protection scope of this disclosure.

[0172] The cleaning system provided in this disclosure includes the cleaning device described above, which includes a carrier device and a cleaning device. The carrier device may include a main body 1, which has a receiving cavity 11 capable of accommodating the cleaning device. This allows the cleaning device to be transported to different floors, enabling it to clean different floors and increasing its cleaning range. Simultaneously, the main body 1 also has a first cleaning through-hole 12 that exposes the cleaning part of the cleaning device. This allows the cleaning device to simultaneously clean surfaces such as steps and railings within the receiving cavity 11 while the carrier device is moving and climbing, further increasing its cleaning range. Furthermore, the cleaning device can complete the cleaning work without leaving the receiving cavity 11 of the carrier device, saving time and steps associated with leaving and re-entering the carrier device, thereby improving cleaning efficiency and the climbing efficiency of the carrier device.

[0173] Secondly, the carrier device provided in this disclosure is equipped with a rotating mechanism 2, which can contact the cleaning device and drive the cleaning device to rotate relative to the main body 1 in the first direction X. This allows the cleaning device to turn within the receiving cavity 11 of the carrier device. Therefore, when the cleaning device is cleaning the surface to be cleaned, rotating the cleaning device by the rotating mechanism 2 can further increase the cleaning range of the cleaning device, thereby further improving the cleaning effect.

[0174] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
