Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to a cleaning module and cleaning equipment. Background Technology

[0002] With the iterative updates and development of technology, cleaning equipment has entered ordinary household life and gradually become widespread. However, cleaning equipment typically has a single, fixed cleaning range, which affects cleaning efficiency. Utility Model Content

[0003] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This section of the application is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] An embodiment of the first aspect of this application provides a cleaning module, including: a cleaning component; a connector; and a driving component. One end of the driving component is connected to the cleaning component via the connector to drive the cleaning component to rotate, and the other end of the cleaning component is a free end. When the driving component drives the cleaning component to rotate in a first direction, the distance between the free end of the cleaning component and the rotation center of the cleaning component is a first distance. When the driving component drives the cleaning component to rotate in a second direction, the distance between the free end of the cleaning component and the rotation center is a second distance. The first distance and the second distance are different, and the first direction is opposite to the second direction.

[0005] For example, the cleaning component includes at least a first segment and a second segment. One end of the first segment is connected to a drive assembly, and the other end of the first segment is movably connected to the second segment. The other end of the second segment is a free end. When the cleaning component switches from rotating in a first direction to rotating in a second direction and / or from rotating in a second direction to rotating in a first direction, the second segment moves relative to the first segment.

[0006] For example, the other end of the first segment is rotatably connected to the second segment.

[0007] For example, the cleaning component also includes a connecting seat, one side of which is connected to the first segment, and the other side of which is rotatably connected to the second segment. The side of the connecting seat facing the second segment is provided with a first limiting surface and a second limiting surface.

[0008] For example, the drive assembly includes: a fixed frame; a power assembly mounted on the fixed frame; a rotating shell connected to the power assembly and rotating under the drive of the power assembly; a lifting member dampedly connected to the fixed frame and spirally connected to the rotating shell; one end of a cleaning component located inside the rotating shell and connected to the lifting member, and the other end of the cleaning component protruding outside the rotating shell; the power assembly drives the rotating shell to rotate in a first direction, and the rotating shell drives the lifting member to descend to a first position; when the power assembly drives the rotating shell to rotate in a second direction, the rotating shell drives the lifting member to rise from the first position to the second position.

[0009] For example, the fixed frame is provided with a first limiting part, and the lifting component is provided with a second limiting part;

[0010] When the power component drives the rotating shell to rotate in the second direction, the rotating shell causes the lifting component to rise from the first position or the second position to the third position. In the third position, the first limiting part and the second limiting part abut against each other to restrict the rotation of the lifting component. The second position is between the first position and the third position.

[0011] For example, the distance between the first position and the third position is 3 to 5 times the distance between the first position and the second position.

[0012] For example, the cleaning component is a soft component, and the rotating shell rotates in the second direction, which can drive the lifting component to continue to rise from the third position to the fourth position, and at least a part of the cleaning component is brought into the rotating shell.

[0013] For example, the cleaning component is a soft component, the lifting component is in the third position, and the power component drives the rotating shell to continue rotating in the second direction so that at least a portion of the cleaning component is brought into the rotating shell.

[0014] For example, the first section includes a fixed section and a transition section, the fixed section is connected to the lifting component, the second section is connected to the transition section, and the second section has a height difference with the fixed section.

[0015] For example, a first locking part is formed on the rotating shell and / or the lifting member. When the lifting member descends to the first position, the first locking part locks the lifting member and the rotating shell so that the lifting member rotates synchronously with the rotating shell.

[0016] For example, a second locking part is formed on the rotating shell and / or the lifting member. When the lifting member rises to the second position, the second locking part locks the lifting member and the rotating shell so that the lifting member rotates synchronously with the rotating shell.

[0017] For example, the rotating shell includes a convex ring and an outer shell portion connected to the outer periphery of the convex ring. The convex ring is sleeved on the power assembly. The lifting component includes a cylinder, which is sleeved between the convex ring and the outer shell portion. The outer wall of the convex ring is provided with at least one protruding post, and the inner wall of the cylinder is provided with a spiral groove. Alternatively, the convex ring is provided with a spiral groove, and the cylinder is provided with at least one protruding post, which is movable along the spiral groove.

[0018] For example, a first locking portion is formed at the first end of the spiral groove, and when the lifting member descends to the first position, at least one protrusion abuts against the first end.

[0019] For example, a second locking part is formed at the second end of the spiral groove. When the lifting member rises to the second position, at least one protrusion abuts against the second end so that the lifting member rotates synchronously with the rotating shell.

[0020] For example, the second locking part includes a steering block rotatably disposed on the rotating shell and a limiting part disposed on the lifting member, or the second locking part includes a steering block rotatably disposed on the lifting member and a limiting part disposed on the rotating shell; when the lifting member rises to the second position, the steering block abuts against the limiting part so that the lifting member and the rotating shell rotate synchronously.

[0021] For example, a first actuating part is also provided on the rotating shell or lifting component, the lifting component is in a second position, the power component drives the rotating shell to rotate in a first direction, the first actuating part contacts the steering block, and the steering block turns.

[0022] For example, when the rotating shell drives the lifting component to descend from the second position to the first position or during the process of descending to the first position, the first actuating part contacts the steering block, and the steering block turns.

[0023] For example, a first limiting part is provided on the fixed frame, and a second limiting part is provided on the lifting component; the power component drives the rotating shell to rotate in the second direction, and the steering block turns after contacting the limiting part, and the lifting component continues to rise to the third position; or the power component drives the rotating shell to rotate in the second direction, and the rotating shell drives the lifting component to rise to the third position; in the third position, the first limiting part and the second limiting part abut against each other, and the second position is between the first position and the third position.

[0024] For example, the cleaning component is a soft component, and the rotating shell rotates in the second direction, which can drive the lifting component to continue to rise from the third position to the fourth position, and at least a part of the cleaning component is brought into the rotating shell.

[0025] For example, a second actuating part is also provided on the rotating shell or lifting component. When the lifting component is in the fourth position or rising to the fourth position, the second actuating part contacts the steering block, and the steering block turns.

[0026] For example, the first actuating part, the limiting part and the second actuating part are formed on the outer peripheral surface of the cylinder, and the steering block is rotatably disposed on the inner wall of the rotating shell.

[0027] For example, a first guide opening is provided on the outer casing.

[0028] For example, the rotating shell also includes an outer shell body detachably connected to the outer shell portion. The outer shell body has a second guide opening corresponding to the first guide opening. The first guide opening and the second guide opening together form a guide groove, through which the cleaning component extends out of the rotating shell.

[0029] For example, the drive assembly also includes a friction element disposed between the fixed frame and the lifting component and connected to the lifting component, and a second limiting portion is disposed on the friction element.

[0030] For example, the mounting bracket includes a base and a boss disposed on the base. The friction member has a first through hole, the boss passes through the first through hole, and at least one protrusion is provided on the inner wall of the first through hole. The protrusion is dampedly connected to the outer periphery of the boss.

[0031] For example, a second through hole is provided on the boss, and the output shaft of the power assembly is connected to the rotating housing through the second through hole.

[0032] For example, the cleaning component is a side brush.

[0033] An embodiment of the second aspect of this application provides a cleaning device, including a device body and a cleaning module as described above, the cleaning module being disposed on the device body.

[0034] The cleaning module provided in this application embodiment has a first distance between the free end of the cleaning component and the rotation center when the driving component drives the cleaning component to rotate in a first direction, and a second distance when the driving component drives the cleaning component to rotate in a second direction. Since the first distance and the second distance are different, and the first direction is opposite to the second direction, the driving component drives the cleaning component to rotate in different directions, resulting in different distances between the free end of the cleaning component and the rotation center, and thus different contact areas between the cleaning component and the surface to be cleaned, resulting in different cleaning ranges. This diversifies the cleaning range of the cleaning equipment, meets the needs of different cleaning ranges, expands the scope of use, and helps to improve the cleaning effect and user satisfaction. Furthermore, different cleaning ranges can be obtained by using the same driving component to drive the cleaning component to rotate in different directions, which simplifies the structure and expands the function of the cleaning equipment without adding parts, which helps to save production costs.

Detailed Implementation

[0062] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided in this application. However, it will be apparent to those skilled in the art that the technical solutions provided in this application can be implemented without one or more of these details.

[0063] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0064] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0065] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an embodiment of the first aspect of this application provides a cleaning module, including: a cleaning component 100; a connector; and a driving component 200. One end of the driving component 200 is connected to the cleaning component 100 via the connector to drive the cleaning component 100 to rotate, and the other end of the cleaning component 100 is a free end 121. When the driving component 200 drives the cleaning component 100 to rotate in a first direction, the distance between the free end 121 of the cleaning component 100 and the rotation center of the cleaning component 100 is a first distance. When the driving component 200 drives the cleaning component 100 to rotate in a second direction, the distance between the free end 121 of the cleaning component 100 and the rotation center is a second distance. The first distance and the second distance are different, and the first direction is opposite to the second direction.

[0066] Among them, the cleaning module is applied to cleaning equipment, which can be a sweeping robot, a mopping robot, a sweeping and mopping robot, or other cleaning equipment that meets the requirements.

[0067] Specifically, cleaning equipment includes, but is not limited to, a machine body, a cleaning system, and a mobility system. These systems coordinate with each other, enabling the cleaning equipment to move autonomously to perform its cleaning function. The functional components constituting these systems are integrated within the machine body. The machine body is used to install and support other parts of the cleaning equipment. It is understood that the cleaning equipment can be a self-moving cleaning device, where a self-moving device automatically performs cleaning operations in a designated area without user intervention.

[0068] The drive assembly 200 and the cleaning component 100 are connected via a connector, allowing one end of the cleaning component 100 to be fixed to the drive assembly 200. This enables the drive assembly 200 to move, thereby moving the cleaning component 100. It is understood that one end of the cleaning component 100 can be connected to a portion of the drive assembly 200, such as connecting one end of the cleaning component 100 to the lifting component 240 mentioned later. Specifically, the connector can be a detachable structure, such as at least one of bolt, plug-in, snap-fit, tenon, or magnetic structures, to achieve a detachable connection between the cleaning component 100 and a portion of the drive assembly 200 (such as the lifting component 240 mentioned later). This facilitates the individual replacement of a damaged cleaning component 100, or replacement with a cleaning component 100 of a different specification or material. Alternatively, the connector can also achieve a fixed connection between the cleaning component 100 and the drive assembly 200. For example, one end of the cleaning component 100 and a part of the structure of the drive assembly 200 (such as the lifting component 240 mentioned later) can be fixedly connected by injection molding. That is, the connector is injection molded, thereby further improving the fixing effect between the cleaning component 100 and the lifting component 240.

[0069] The cleaning component 100 is driven to rotate by the driving component 200, causing the cleaning component 100 to interfere with the surface to be cleaned, thereby achieving the cleaning operation on the surface to be cleaned. For example, Figure 2 and Figure 4As shown, the rotation center O of the cleaning component 100 can be understood as the center at which the driving component 200 drives the cleaning component 100 to rotate, and the free end 121 of the cleaning component 100 can be understood as the end of the cleaning component 100 away from the driving component 200. During the cleaning operation, at least the free end 121 of the cleaning component 100 is in interference contact with the surface to be cleaned. It can be understood that the distance between the free end 121 of the cleaning component 100 and the rotation center of the cleaning component 100 is related to the cleaning range of the cleaning component 100. For example, a longer distance between the free end 121 of the cleaning component 100 and the rotation center of the cleaning component 100 results in a larger contact area between the cleaning component 100 and the surface to be cleaned, thus having a larger cleaning range; a shorter distance between the free end 121 of the cleaning component 100 and the rotation center of the cleaning component 100 results in a smaller contact area between the cleaning component 100 and the surface to be cleaned, thus having a smaller cleaning range.

[0070] In this embodiment, as Figure 2 As shown, when the drive assembly 200 drives the cleaning component 100 to rotate in the first direction, the distance between the free end 121 of the cleaning component 100 and the rotation center of the cleaning component 100 is the first distance, such as... Figure 2 As shown in H1, as Figure 4 As shown, when the drive assembly 200 drives the cleaning component 100 to rotate in the second direction, the distance between the free end 121 of the cleaning component 100 and the center of rotation is the second distance, as shown. Figure 4 As shown in H2, due to the difference between the first distance and the second distance, the first direction is opposite to the second direction. Therefore, the drive assembly 200 drives the cleaning component 100 to rotate in different directions, resulting in different distances between the free end 121 of the cleaning component 100 and the center of rotation. This results in different contact areas between the cleaning component 100 and the surface to be cleaned, and thus different cleaning ranges. This diversifies the cleaning range of the cleaning equipment, meets the needs of different cleaning ranges, expands the scope of use, and helps improve the cleaning effect and user satisfaction. Furthermore, different cleaning ranges can be obtained by using the same drive assembly 200 to drive the cleaning component 100 to rotate in different directions, which simplifies the structure and expands the function of the cleaning equipment without adding parts, thus helping to save production costs.

[0071] Among them, such as Figures 1 to 5 As shown, the first direction S and the second direction R refer to the direction of rotation. The first direction S can be either clockwise or counterclockwise, and the second direction R can be either clockwise or counterclockwise. For example, please refer to... Figures 1 to 5 As shown, when the first direction S is clockwise, the second direction R is counterclockwise.

[0072] The first distance can be greater than the second distance, or the first distance can be less than the second distance.

[0073] Furthermore, the cleaning system may include a dry cleaning system, i.e., the cleaning equipment can be a robot vacuum cleaner; or, the cleaning system may include both wet and dry cleaning systems, i.e., the cleaning equipment can be a robot vacuum and mop combo, etc.

[0074] The wet cleaning system may include a mopping module, which can be used for mopping, washing, etc., and the cleaning components may include a mop, cleaning roller, etc.

[0075] The dry cleaning system can include a sweeping module, a dustbin, and a vacuum fan. The sweeping module, which has some interference with the ground, sweeps up the debris on the ground and brings it to the suction port between the sweeping module and the dustbin. Then, the suction fan generates and draws the debris into the dustbin with the suction gas. The sweeping module can be a brush plate, roller brush, etc.

[0076] Furthermore, the dry cleaning system may also include a side brush module, which is rotatably connected to the main body of the machine and is used to move debris and other objects outside the sweeping module area to the sweeping module area of ​​the cleaning system.

[0077] The cleaning module provided in this application embodiment can be a side brush module, that is, the cleaning component 100 is a side brush. It can be understood that the cleaning module can also be a mopping module or a sweeping module, such as the cleaning component 100 being a brush plate, a mop plate, etc.

[0078] like Figure 6 As shown, in some possible embodiments provided in this application, the cleaning component 100 includes at least a first segment 110 and a second segment 120. One end of the first segment 110 is connected to the drive assembly 200, and the other end of the first segment 110 is movably connected to the second segment 120. The other end of the second segment 120 is a free end 121. When the cleaning component 100 switches from rotating along a first direction to rotating along a second direction and / or from rotating along a second direction to rotating along a first direction, the second segment 120 is movable relative to the first segment 110.

[0079] In this embodiment, the first segment 110 and the second end of the cleaning component 100 are movably connected, making the connection between the end of the cleaning component 100 connected to the drive assembly 200 and the free end 121 a movable structure; that is, the entire cleaning component 100 is a movable structure. When the cleaning component 100 switches from rotating along a first direction to rotating along a second direction, and / or when the cleaning component 100 switches from rotating along a second direction to rotating along a first direction, the second segment 120 moves relative to the first segment 110. This causes the distance between the free end 121 of the cleaning component 100 and the rotation center to change, switching between the first distance and the second distance to achieve a switching of the cleaning range. Therefore, by setting the connection between the end of the cleaning component 100 connected to the drive assembly 200 and the free end 121 as a movable structure, and cooperating with the drive assembly 200 rotating in different directions, the switching of the cleaning range can be achieved. This configuration is simple in structure and easy to implement.

[0080] like Figure 6 As shown, in some possible embodiments provided in this application, the other end of the first segment 110 is rotatably connected to the second segment 120.

[0081] This embodiment discloses a specific method for the movable connection of the first segment 110 and the second segment 120. The movable connection between the first segment 110 and the second segment 120 of the cleaning member 100 is achieved by rotatably connecting them. This rotatable connection is easy to implement and has a simple structure. It is understood that the first segment 110 and the second segment 120 can also be movably connected by extension or extension, or by other means.

[0082] like Figure 6 As shown, in some possible embodiments provided in this application, the cleaning component 100 further includes a connecting seat 130. One side of the connecting seat 130 is connected to the first segment 110, that is, one side of the connecting seat 130 is fixed to the end of the first segment 110 facing the second segment 120. The first segment 110 and the second segment 120 are rotatably connected through the other side of the connecting seat 130 to the second segment 120. Specifically, the second segment 120 can be hinged to the connecting seat 130 by a pin to achieve a rotatable connection with the fixed seat. This arrangement is simple in structure, easy to implement, and has a low cost.

[0083] like Figure 2 , Figure 4 , Figure 7 As shown, further, the connecting seat 130 is provided with a first limiting surface 131 and a second limiting surface 132 on the side facing the second segment 120. The provision of the first limiting surface 131 and the second limiting surface 132 limits the rotation range of the second segment 120 relative to the first segment 110, so that during the cleaning process of the cleaning component 100 rotating in the first direction, such as... Figure 2As shown, the second segment 120 can abut against the first limiting surface 131. At this time, the distance between the free end 121 of the cleaning component 100 and the center of rotation is the first distance. As the cleaning component 100 continues to rotate in the first direction, under the limiting action of the first limiting surface 131, the entire cleaning component 100 is considered a fixed structure, ensuring a good cleaning effect. Figure 4 As shown, during the cleaning process of the cleaning component 100 rotating in the second direction, the second segment 120 can abut against the second limiting surface 132. At this time, the distance between the free end 121 of the cleaning component 100 and the rotation center is the second distance. As the cleaning component 100 continues to rotate in the second direction, under the limiting action of the second limiting surface 132, the entire cleaning component 100 is regarded as a fixed structure, ensuring a good cleaning effect.

[0084] Understandably, to ensure a good limiting effect, the structure and shape of the first limiting surface 131 and the second limiting surface 132 can be reasonably set. For example, the first limiting surface 131 can be arranged individually or in pairs, and the second limiting surface 132 can be arranged individually or in pairs. The first limiting surface 131 can be a plane, a curved surface, an irregular surface, etc., and the second limiting surface 132 can be a plane, a curved surface, an irregular surface, etc.

[0085] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some possible embodiments provided in this application, the drive assembly 200 includes a fixed frame 210, a power assembly 220, a rotating shell 230, and a lifting member 240. The power assembly 220 is mounted on the fixed frame 210, which provides support for the power assembly 220. For example, the entire drive assembly 200 can be fixed to the main body of the cleaning equipment via the fixed frame 210. The rotating shell 230 is connected to the power assembly 220 and rotates under the drive of the power assembly 220. The lifting member 240 is dampedly connected to the fixed frame 210 and helically connected to the rotating shell 230. One end of the cleaning component 100 is located inside the rotating shell 230 and connected to the lifting member 240, while the other end of the cleaning component 100 protrudes outside the rotating shell 230, i.e., the free end 121 of the cleaning component 100 protrudes outside the rotating shell 230. The power component 220 drives the rotating shell 230 to rotate in the first direction, and the rotating shell 230 drives the lifting component 240 to descend to the first position. When the power component 220 drives the rotating shell 230 to rotate in the second direction, the rotating shell 230 drives the lifting component 240 to rise from the first position to the second position.

[0086] The spiral connection refers to the helical engagement between the lifting component 240 and the rotating shell 230, such as a threaded engagement, a helical groove 2421, and a protrusion 2311, to enable the power component 220 to drive the cleaning component 100 to rotate. For example, when the circumferential rotation of the lifting component 240 is not limited, the power component 220 drives the rotating shell 230 to rotate, and the lifting component 240 can move up and down relative to the rotating shell 230 in a spiral manner along the rotation axis of the rotating shell 230. When the circumferential rotation of the lifting component 240 is limited, the power component 220 drives the rotating shell 230 to rotate, and the lifting component 240 can move up and down relative to the rotating shell 230 in a linear manner along the rotation axis of the rotating shell 230.

[0087] Damping connection refers to a resistance to the relative movement of the lifting component 240 and the fixed frame 210. When the power component 220 drives the rotating housing 230 to rotate, the lifting component 240 moves relative to the fixed frame 210 under the influence of the rotating housing 230. The damping connection applies a force to the movement of the lifting component 240 relative to the fixed frame 210, creating a speed difference between the rotational speed of the lifting component 240 and the rotating housing 230. For example, the lifting component 240 may stop rotating or rotate at a lower speed than the rotating housing 230, thus enabling the lifting component 240 to lift and lower under the helical connection with the rotating housing 230. Specifically, the method of achieving a damping connection between the lifting component 240 and the fixed frame 210 is not limited. For example, it can be achieved by increasing the coefficient of friction of the contact surface between the lifting component 240 and the fixed frame 210.

[0088] In this embodiment, one end of the cleaning component 100 is fixedly connected to the lifting component 240, the lifting component 240 is dampedly connected to the fixed frame 210, the rotating shell 230 is spirally connected to the lifting component 240, and the power component 220 is drivenly connected to the rotating shell 230. When the power component 220 drives the rotating shell 230 to rotate, there is friction between the power component 220 and the fixed frame 210, which causes the rotation of the lifting component 240 to stop or the rotation speed to be less than the rotation speed of the rotating shell 230. As a result, the lifting component 240 rises or falls along the rotation axis of the rotating shell 230 in a spiral or linear manner.

[0089] Among them, such as Figure 2 and Figure 3 As shown, the power component 220 drives the rotating shell 230 to rotate in the first direction. The rotating shell 230 drives the lifting component 240 to descend to the first position. The cleaning component 100 falls to contact the surface to be cleaned. At this time, the distance between the free end 121 of the cleaning component 100 and the rotation center of the cleaning component 100 is the first distance. The cleaning component 100 performs cleaning operations in the first direction under the drive of the power component 220.

[0090] like Figure 4 and Figure 5As shown, the power component 220 drives the rotating shell 230 to rotate in the second direction. The rotating shell 230 drives the lifting component 240 to rise from the first position to the second position. The cleaning component 100 is still in contact with the surface to be cleaned. At this time, the distance between the free end 121 of the cleaning component 100 and the rotation center of the cleaning component 100 is the second distance. The cleaning component 100 performs cleaning operations in the second direction under the drive of the power component 220.

[0091] In other words, the cleaning component 100 is in a cleaning position in both the first and second positions. In the first position, the cleaning component 100 rotates along a first direction under the drive of the power component 220, the rotating shell 230, and the lifting component 240. The distance between the free end 121 of the cleaning component 100 and the center of rotation of the cleaning component 100 is a first distance, and the cleaning range is a first cleaning range. In the second position, the cleaning component 100 rotates along a second direction under the drive of the power component 220, the rotating shell 230, and the lifting component 240. The distance between the free end 121 of the cleaning component 100 and the center of rotation of the cleaning component 100 is a second distance, and the cleaning range is a second cleaning range. Thus, the needs of different cleaning ranges of the cleaning equipment are met, the scope of use is expanded, and the cleaning effect is improved.

[0092] like Figure 8 , Figure 9 and Figure 10 As shown, in some possible embodiments provided in this application, the fixed frame 210 is provided with a first limiting part 211, and the lifting member 240 is provided with a second limiting part 241; when the power component 220 drives the rotating shell 230 to rotate in the second direction, the rotating shell 230 drives the lifting member 240 to rise from the first position or the second position to the third position. In the third position, the first limiting part 211 and the second limiting part 241 abut against each other to restrict the rotation of the lifting member 240. The second position is between the first position and the third position.

[0093] In the embodiments provided in this application, the directions corresponding to rising and falling can be understood as the directions of the rotation axis of the cleaning component 100. The contact surfaces of the first limiting part 211 and the second limiting part 241 have a preset height along the direction of the rotation axis of the cleaning component 100.

[0094] In this embodiment, since at least one of the contact surfaces of the first limiting part 211 and the second limiting part 241 has a preset height along the direction of the rotation axis of the cleaning member 100, when the lifting member rises to the third position, after the first limiting part 211 and the second limiting part 241 abut, the circumferential rotation of the lifting member 240 is limited. Thus, when the power assembly 220 drives the rotating shell 230 to rotate in the second direction, the rotating shell 230 drives the lifting member 240 to rise from the first position to the third position, or from the second position to the third position, so that after the first limiting part 211 and the second limiting part 241 abut, starting from the third position, since the second limiting part 241 and the first limiting part 211 remain in contact, the circumferential rotation of the lifting member 240 is continuously limited. In this posture, the power component 220 drives the rotating shell 230 to continue rotating in the second direction. The lifting component 240 can rise linearly relative to the rotating shell 230 along its rotation axis, thereby causing the cleaning component 100 to rise linearly relative to the rotating shell 230 along its rotation axis. This allows the cleaning component 100 to gradually separate from the surface to be cleaned, thus enabling it to detach from the surface. In other words, the third position ensures that driving the rotating shell 230 to continue rotating in the second direction guarantees that the cleaning component 100 can smoothly detach from the surface to be cleaned, preparing for subsequent storage of the cleaning component 100.

[0095] It is understandable that the rotating shell 230 can drive the lifting component 240 to rise directly from the first position to the third position, or the rotating shell 230 can drive the lifting component 240 to rise directly from the second position to the third position. The third position can be understood as the starting position for storing the cleaning component 100.

[0096] In some possible embodiments provided in this application, the distance between the first position and the third position is 3 to 5 times the distance between the first position and the second position. For example, the distance between the third position and the first position is L1, and the distance between the second position and the first position is L2. L1 can be 3L2, 3.5L2, 4L2, 4.5L2, or 5L2, etc. In this way, there is sufficient distance between the third position and the second position for the lifting member 240 to move upward, so that the cleaning member 100 is pulled further into the rotating housing 230, allowing the cleaning member 100 to be fully lifted off the ground.

[0097] When the cleaning component 100 is a soft component, it is pulled into the rotating housing 230. The portion of the cleaning component 100 fixed to one end of the lifting member 30 gradually deforms. As the rotating housing 230 continues to rotate, the deformation of the cleaning component 100 creates a stalling effect, thus stopping the rotation of the rotating housing 230. Alternatively, the lifting member 240 rises to contact the power component 220, thereby stopping the rotation of the rotating housing 230. Alternatively, the power component 220 can be stopped by a preset control program when the cleaning component 100 reaches the required lifting height.

[0098] For example, when the lifting member 240 rotates and rises from the first position to the third position, the lifting member 240 moves upward 0.5 mm axially. When the lifting member 240 is stopped by the first limiting part 211 and the second limiting part 241 and continues to rise linearly to the second position, the lifting member 240 continues to move upward 2.0 mm in the direction of the rotation axis of the cleaning member 100.

[0099] It should be noted that when the first limiting part 211 and the second limiting part 241 abut, there is a certain distance between the lifting member 240 and the base 212 of the fixed frame 210. Thus, when the lifting member 240 reaches the third position and can no longer rotate, under the driving action of the power component 220, the rotating shell 230 continues to rotate to drive the lifting member 240 to move upward, and at the same time drive the cleaning component 100 to continue to move upward. The free end 121 of the cleaning component 100 can move upward as a whole, further separating from the ground.

[0100] like Figure 8 and Figure 9 As shown, in some possible embodiments provided in this application, the cleaning component 100 is a soft component, and the rotating shell 230 rotates in the second direction, which can drive the lifting component 240 to continue to rise from the third position to the fourth position, and at least a portion of the cleaning component 100 is brought into the rotating shell 230.

[0101] When the cleaning component 100 is in the third position, the first limiting part 211 and the second limiting part 241 abut against each other, limiting the circumferential rotation of the lifting component 240. Therefore, the rotating shell 230 continues to rotate in the second direction, which can drive the lifting component 240 to continue to rise. The lifting component 240 continues to rise from the third position to the fourth position, so that at least a portion of the soft cleaning component 100 is brought into the rotating shell 230 to realize the storage operation of the cleaning component 100. This also increases the height of the cleaning component 100 off the ground, reduces the possibility of soiling the cleaned ground due to the cleaning component 100 contacting the surface to be cleaned, or the possibility of wear due to the cleaning component 100 contacting the ground in a non-working state, and improves the service life of the cleaning component 100.

[0102] The second position is located between the first and third positions. That is, the axial height of the second position relative to the ground is less than that of the third position relative to the ground, and the axial height of the second position relative to the ground is greater than that of the first position relative to the ground.

[0103] Thus, by setting the first limiting part 211 and the second limiting part 241, when the lifting member 240 rotates and rises to the third position, the second limiting part 241 abuts against the first limiting part 211, and the rotation of the lifting member 240 is restricted. At this time, if the rotating shell 230 continues to rotate, the lifting member 240 will rise linearly to the fourth position. During the linear rise of the lifting member 240, since the rotating shell 230 continues to rotate, and one end of the cleaning member 100 is fixed to the lifting member 240 and does not rotate with the rotating shell 230, a part of the cleaning member 100 will be dragged into the rotating shell 230, thereby partially storing it in the rotating shell 230, so that the other end of the cleaning member 100 is suspended at a higher position from the ground.

[0104] The fourth position can be understood as the termination position of the cleaning component 100, where the cleaning component 100 is in a non-cleaning state, detached from the surface to be cleaned. At least a portion of the cleaning component 100 is brought into the rotating housing 230; this could mean the entire cleaning component 100 is brought into the rotating housing 230, or a portion of the cleaning component 100 is brought into the rotating housing 230 while another portion remains outside the rotating housing 230. This is understandable. Figure 8 The cleaning component 100 has been stored inside the rotating shell, which can be understood as the lifting component being in any position between the third and fourth positions, or it can be understood as the lifting component being in the fourth position.

[0105] In some embodiments, the rotating housing 230 drives the lifting member 240 to rise from a first position or a second position to a third position. The first limiting part 211 and the second limiting part 241 abut against each other, limiting the circumferential rotation of the lifting member 240. At this time, in this posture, the power component 220 drives the rotating housing 230 to continue rotating in the second direction, forcing the soft rubber cleaning part 100 around the lifting member 240 to deform, achieving the effect of the bristles lifting off the ground. Thus, at least a portion of the cleaning part 100 can be brought into the rotating housing 230, realizing the storage of the cleaning part 100. When the cleaning part 100 reaches the deformation limit, the power component 220 stalls and stops working to complete the storage operation of the cleaning part 100. It can be understood that when the power component 220 stalls and stops working, the entire cleaning part 100 can be brought into the rotating housing 230, or a portion of the cleaning part 100 can be brought into the rotating housing 230, while another portion of the cleaning part 100 remains outside the rotating housing 230. Figure 6As shown, in some possible embodiments provided in this application, the first segment 110 includes a fixed segment 111 and a transition segment 112. The fixed segment 111 is connected to the lifting member 240, and the second segment 120 is connected to the transition segment 112. The second segment 120 and the fixed segment 111 have a height difference. That is, the transition segment 112 is provided such that the fixed segment 111 and the second segment 120 form a height difference, i.e., the free end 121 of the cleaning member 100 and the end connected to the lifting member 240 have a height difference. Specifically, the height of the second segment 120 is lower than that of the fixed segment 111. By suspending at least part of the second segment 120 outside the rotating housing 230, when the lifting member 240 descends to the first position and rises to the second position, the second segment 120 suspended outside the rotating housing 230 can contact the surface to be cleaned, such as the free end 121 of the second segment 120 can contact the surface to be cleaned, so as to perform cleaning operations. When the cleaning operation is completed and the cleaning component 100 needs to be lifted, the power component 220 drives the rotating shell 230 to rotate in the second direction. The rotating shell 230 drives the lifting component 240 to rise from the first position or the second position to the third position. The first limiting part 211 and the second limiting part 241 abut against the circumferential movement limit of the lifting component 240. The lifting component 240 drives the cleaning component 100 to rise in a straight line along the rotation axis of the rotating shell 230 relative to the rotating shell 230. At this time, the cleaning component 100 is put away. The rotating shell 230 continues to rotate in the second direction, and the lifting component 240 drives the cleaning component 100 to continue to rise. The lifting component 240 continues to rise from the third position to the fourth position. The transition section 112 is dragged into the rotating shell 230. The space inside the rotating shell 230, such as the guide groove 234, is limited. The fixed section 111 and the transition section 112 will be squeezed and deformed. The transition section 112 will twist during the deformation process, rotating the second section 120 upward by a certain angle, so that the second section 120 achieves an upward tilting effect, thereby greatly increasing the ground clearance of the cleaning component 100.

[0106] like Figure 10 As shown, in some possible embodiments provided in this application, a first locking portion 2422 is formed on the rotating shell 230 and / or the lifting member 240. When the lifting member 240 descends to the first position, the first locking portion 2422 locks the lifting member 240 and the rotating shell 230 so that the lifting member 240 and the rotating shell 230 rotate synchronously. In this way, the rotating shell 230 rotates along the first direction under the drive of the power component 220, so that the cleaning member 100 connected to the lifting member 240 can rotate along the first direction and reliably and stably contact the surface to be cleaned, thereby realizing the cleaning operation and ensuring a good cleaning effect.

[0107] The first locking part 2422 can be provided on the rotating shell 230, or the first locking part 2422 can be provided on the lifting member 240, or the first locking part 2422 can be provided on both the rotating shell 230 and the lifting member 240.

[0108] In some possible embodiments provided in this application, a second locking portion is formed on the rotating shell 230 and / or the lifting member 240. When the lifting member 240 rises to the second position, the second locking portion locks the lifting member 240 and the rotating shell 230 so that the lifting member 240 and the rotating shell 230 rotate synchronously. In this way, the rotating shell 230 rotates in the second direction under the drive of the power component 220, so that the cleaning member 100 connected to the lifting member 240 can rotate in the second direction and reliably and stably contact the surface to be cleaned, thereby realizing the cleaning operation and ensuring a good cleaning effect.

[0109] The second locking part can be provided on the rotating shell 230, or the second locking part can be provided on the lifting member 240, or the second locking part can be provided on both the rotating shell 230 and the lifting member 240.

[0110] like Figure 10 , Figure 11 and Figure 12 As shown, in some possible embodiments provided in this application, the rotating shell 230 includes a convex ring 231 and an outer shell portion 232 connected to the outer periphery of the convex ring 231. The convex ring 231 is sleeved on the power assembly 220, so that the power assembly 220 is connected to the rotating shell 230. The lifting member 240 includes a cylindrical body 242, which is sleeved between the convex ring 231 and the outer shell portion 232. The outer wall of the convex ring 231 is provided with at least one protruding post 2311, and the inner wall of the cylindrical body 242 is provided with a spiral groove 2421. The at least one protruding post 2311 can move along the spiral groove 2421, so that the lifting member 240 and the rotating shell 230 are spirally connected. Alternatively, the convex ring 231 is provided with a spiral groove, and the cylindrical body 242 is provided with at least one protruding post. The at least one protruding post can move along the spiral groove, so that the lifting member 240 and the rotating shell 230 are spirally connected.

[0111] In other words, a protruding post 2311 can be provided on one of the protruding ring 231 and the cylinder 424, and a spiral groove 2421 can be provided on the other of the protruding ring 231 and the cylinder 424. The lifting component 240 and the rotating shell 230 are spirally connected by the movement of the protruding post 2311 along the spiral groove 2421.

[0112] Furthermore, the number of protrusions 2311 and spiral grooves 2421 is the same, both being multiple, for example, three each. Exemplarily, the spiral grooves 2421 gradually extend towards the ground along the first direction.

[0113] like Figure 10 As shown, in some possible embodiments provided in this application, a first locking part 2422 is formed at the first end of the spiral groove 2421, and when the lifting member 240 descends to the first position, at least one protrusion 2311 abuts against the first end.

[0114] The spiral groove 2421 includes a first end and a second end. The first end of the spiral groove 2421 is located near the upper end of the cylinder 242, but does not extend through the upper end of the cylinder 242. A first locking part 2422 is formed at the first end of the spiral groove 2421. When the lifting member 240 descends to the first position, the protrusion 2311 abuts against the first end, so that the lifting member 240 and the rotating shell 230 rotate synchronously, driving the cleaning member 100 to rotate for cleaning operations.

[0115] The second end of the spiral groove 2421 is located at the lower end of the cylinder 242. The second end of the spiral groove 2421 is located near the lower end of the cylinder 242. The second locking part is formed at the second end of the spiral groove 2421. When the lifting member 240 rises to the second position, at least one protrusion 2311 abuts against the second end so that the lifting member 240 and the rotating shell 230 rotate synchronously, driving the cleaning member 100 to rotate for cleaning operations.

[0116] It is understood that in some embodiments, the second end of the spiral groove 2421 extends through the lower end of the cylinder 242 for the protrusion 2311 to be inserted into the spiral groove 2421. It is inconvenient to provide a second locking part. In this case, the second locking part can also be presented by other structures.

[0117] like Figures 13 to 16 As shown, in some possible embodiments provided in this application, the second locking part includes a steering block 233 rotatably disposed on the rotating shell 230 and a limiting part 243 disposed on the lifting member 240, or the second locking part includes a steering block 233 rotatably disposed on the lifting member 240 and a limiting part 243 disposed on the rotating shell 230; when the lifting member 240 rises to the second position, the steering block 233 abuts against the limiting part 243 so that the lifting member 240 and the rotating shell 230 rotate synchronously.

[0118] In other words, the steering lever 233 is rotatably mounted on one of the rotating housing 230 and the lifting member 240, and the limiting part 243 is mounted on the other of the rotating housing 230 and the lifting member 240. When the lifting member 240 rises to the second position, such as Figure 16 As shown, the lifting component 240 and the rotating shell 230 are locked by the abutting of the steering block 233 and the limiting part 243, so that the lifting component 240 and the rotating shell 230 rotate synchronously, driving the cleaning component 100 to rotate for cleaning operation.

[0119] like Figure 11, Figure 17 As shown, in some possible embodiments provided in this application, a first actuating part 244 is also provided on the rotating shell 230 or the lifting member 240. The lifting member 240 is in a second position. The power component 220 drives the rotating shell 230 to rotate in a first direction. The first actuating part 244 contacts the steering block 233, and the steering block 233 turns.

[0120] like Figure 16 As shown, when the lifting member 240 is in the second position, the power component 220 drives the rotating shell 230 to rotate in the first direction, causing the steering block 233 to abut against the limiting part 243, locking the lifting member 240 and the rotating shell 230, so that the lifting member 240 and the rotating shell 230 rotate synchronously. In this posture, the power component 220 drives the rotating shell 230 to rotate in the first direction, as... Figure 17 As shown, the first actuating part 244 on the rotating shell 230 or the lifting component 240 contacts the steering block 233, and the steering block 233 turns. If the steering block 233 rotates by a first preset angle, the subsequent steering block 233 can turn at the preset angle, without interfering with or affecting the subsequent movement of the lifting component 240 and the rotating shell 230, so as to ensure that the cleaning component 100 can run according to the preset trajectory.

[0121] like Figure 18 As shown, in some possible embodiments provided in this application, when the rotating shell 230 drives the lifting component 240 to descend from the second position to the first position or during the process of descending to the first position, the first actuating part 244 contacts the steering block 233, and the steering block 233 turns.

[0122] In other words, such as Figure 17 As shown, after the steering lever 233 turns, the power assembly 220 drives the rotating housing 230 to continue rotating in the first direction. When the rotating housing 230 drives the lifting component 240 to descend from the second position to the first position, or during the process of descending to the first position, as shown... Figure 18 As shown, the first actuating part 244 contacts the steering block 233, and the steering block 233 turns again. If the steering block 233 rotates to a second preset angle, this operation allows the subsequent steering block 233 to turn at the preset angle without interfering with or affecting the subsequent movement of the lifting member 240 and the rotating shell 230, thus ensuring that the cleaning member 100 can run along the preset trajectory. If the problem of the subsequent drive assembly 200 rotating in the second direction causing the steering block 233 to abut against the limiting part 243 again, locking the lifting member 240 and the rotating shell 230 and preventing the lifting member 240 from rising smoothly can be avoided, it is thus ensured that during the subsequent drive assembly 200 rotating in the second direction, the steering block 233 and the limiting part 243 will not abut against each other, and the lifting member 240 can smoothly reach the third position.

[0123] like Figure 8 , Figure 9 , Figure 10 , Figure 19 , Figure 20 As shown, in some possible embodiments provided in this application, the fixed frame 210 is provided with a first limiting part 211, and the lifting member 240 is provided with a second limiting part 241; the power component 220 drives the rotating shell 230 to rotate in the second direction, and the steering block 233 turns after contacting the limiting part 243, and the lifting member 240 continues to rise to the third position; or the power component 220 drives the rotating shell 230 to rotate in the second direction, and the rotating shell 230 drives the lifting member 240 to rise to the third position; in the third position, the first limiting part 211 and the second limiting part 241 abut against each other, and the second position is between the first position and the third position.

[0124] The contact surfaces of the first limiting part 211 and the second limiting part 241 have a preset height in the vertical direction. When the first limiting part 211 and the second limiting part 241 come into contact, the circumferential rotation of the lifting member 240 is limited. At this time, driven by the rotating shell 230, the lifting member 240 can rise in a straight line along the rotation axis of the rotating shell 230 relative to the rotating shell 230, thereby driving the cleaning part 100 to rise in a straight line along the rotation axis of the rotating shell 230 relative to the rotating shell 230.

[0125] In this embodiment, during the rotation of the aforementioned rotating shell 230 in the second position along the first direction, the first actuating part 244 contacts the steering block 233, causing the steering block 233 to turn; and during the process of the rotating shell 230 driving the lifting member 240 to descend from the second position to the first position, the first actuating part 244 contacts the steering block 233, causing the steering block 233 to turn. In both of these cases, the steering block 233 turns. Therefore, during the process of the power assembly 220 driving the rotating shell 230 to rotate and rise in the second direction to the third position (either from the second position to the third position or from the first position to the third position), the steering block 233, having already turned, will not abut against the limiting part 243. Figure 19 and Figure 20 As shown, after the steering lever 233 contacts the limiting part 243, steering will not lock the lifting member 240 and the rotating shell 230, or, as Figure 20 As shown, the steering block 233 and the limiting part 243 will not contact each other and will not lock the lifting member 240 and the rotating shell 230, so as to ensure that the lifting member 240 can rise smoothly to the third position.

[0126] like Figure 8 and Figure 9As shown, in the third position, the first limiting part 211 and the second limiting part 241 abut against each other, limiting the circumferential rotation of the lifting member 240. In this posture, the power component 220 drives the rotating shell 230 to continue rotating in the second direction. The lifting member 240 can rise in a straight line along the rotation axis of the rotating shell 230 relative to the rotating shell 230, thereby driving the cleaning component 100 to rise in a straight line along the rotation axis of the rotating shell 230 relative to the rotating shell 230. This allows the cleaning component 100 to gradually separate from the surface to be cleaned, thus enabling the cleaning component 100 to detach from the surface to be cleaned. In other words, the setting of the third position ensures that driving the rotating shell 230 to continue rotating in the second direction can ensure that the cleaning component 100 can smoothly detach from the surface to be cleaned, preparing for the subsequent storage of the cleaning component 100.

[0127] It is understandable that the rotating shell 230 can drive the lifting component 240 to rise directly from the first position to the third position, or the rotating shell 230 can drive the lifting component 240 to rise directly from the second position to the third position. The third position can be understood as the starting position for storing the cleaning component 100.

[0128] like Figure 9 and Figure 10 As shown, in some possible embodiments provided in this application, the cleaning component 100 is a soft component, and the rotating shell 230 rotates in the second direction, which can drive the lifting component 240 to continue to rise from the third position to the fourth position, and at least a portion of the cleaning component 100 is brought into the rotating shell 230.

[0129] When the cleaning component 100 is in the third position, the first limiting part 211 and the second limiting part 241 abut against each other, limiting the circumferential rotation of the lifting component 240. Therefore, the rotating shell 230 continues to rotate in the second direction, which can drive the lifting component 240 to continue to rise. The lifting component 240 continues to rise from the third position to the fourth position, so that at least a portion of the soft cleaning component 100 is brought into the rotating shell 230 to realize the storage operation of the cleaning component 100. This also increases the height of the cleaning component 100 off the ground, reduces the possibility of soiling the cleaned ground due to the cleaning component 100 contacting the surface to be cleaned, or the possibility of wear due to the cleaning component 100 contacting the ground in a non-working state, and improves the service life of the cleaning component 100.

[0130] The fourth position can be understood as the termination position of the cleaning component 100, where the cleaning component 100 is in a non-cleaning state, detached from the surface to be cleaned. At least a portion of the cleaning component 100 is brought into the rotating housing 230; this could mean the entire cleaning component 100 is brought into the rotating housing 230, or a portion of the cleaning component 100 is brought into the rotating housing 230 while another portion remains outside the rotating housing 230. This is understandable. Figure 8The cleaning component 100 has been stored inside the rotating shell, which can be understood as the lifting component being in any position between the third and fourth positions, or it can be understood as the lifting component being in the fourth position.

[0131] like Figure 11 and Figure 21 As shown, in some possible embodiments provided in this application, a second actuating part 245 is further provided on the rotating shell 230 or the lifting member 240. During the process of the lifting member 240 being in the fourth position or rising to the fourth position, the second actuating part 245 contacts the steering block 233, and the steering block 233 turns. If the steering block 233 rotates by a preset angle to reset the steering block 233 to the initial position, the steering block 233 and the limiting part 243 will not lock the lifting member 240 and the rotating shell 230 when the rotating shell 230 rotates along the first direction to drive the lifting member 240 to the first position or during the process of descending to the first position. This ensures that the lifting member 240 can descend smoothly to the first position. When the rotating shell 230 rotates along the second direction to drive the lifting member 240 to the second position, the steering block 233 and the limiting part 243 lock the lifting member 240 and the rotating shell 230 to ensure that cleaning operations can be performed.

[0132] like Figure 11 As shown, in some possible embodiments provided in this application, the first actuating part 244, the limiting part 243, and the second actuating part 245 are formed on the outer peripheral surface of the cylinder 242, which has a simple structure and is easy to implement.

[0133] Among them, such as Figure 11 As shown, the first actuating part 244 and the second actuating part 245 can be protrusions or recesses formed on the outer peripheral surface of the cylinder 242, and the limiting part 243 can be a protrusion or recess formed on the outer peripheral surface of the cylinder 242. Specifically, as Figure 11 As shown, a lateral and top opening groove is formed on the outer periphery of a portion of the cylinder 242. A protrusion is provided at one end of the groove to form a first actuating part 244, and a protrusion is provided at the other end of the groove to form a second actuating part 245. A groove is formed on the side wall of the groove near the first end, and a limiting part 243 is formed at the end of the groove near the second actuating part 245. During the relative rotation of the rotating shell 230 and the lifting member 240, the steering block 233 can move within the groove to contact, collide with, or abut against the limiting part 243, the first actuating part 244, and the second actuating part 245, respectively, to achieve steering or limiting functions.

[0134] Among them, such as Figures 13 to 21As shown, the steering block 233 is rotatably disposed on the inner wall of the rotating housing 230, such as the steering block 233 being rotatably connected to the rotating housing 230 via a rotating shaft. The steering block 233 may have multiple limiting surfaces in its circumferential direction to facilitate contact, collision, or abutment with the limiting part 243, the first actuating part 244, and the second actuating part 245, thereby achieving steering or limiting functions.

[0135] Specifically, the steering block 233 is roughly a hexahedral structure, including a first set of opposite faces, a second set of opposite faces, and a third set of opposite faces, with each set of opposite faces having a roughly identical structure. The first set of opposite faces is arranged perpendicular to the rotating shaft, which passes through at least one face of the first set of opposite faces and is rotatably connected to the steering block 233. It can be understood that the other end of the rotating shaft can be fixed to the rotating housing 230. The second and third sets of opposite faces of the steering block 233 are distributed around the rotating shaft; the second set of opposite faces is concave arc-shaped, and the third set of opposite faces is concave V-shaped. Thus, during the relative rotation of the rotating housing 230 and the lifting component 240, the limiting faces on the second and third sets of opposite faces of the steering block 233 can contact, collide with, or abut against the limiting part 243, the first actuating part 244, and the second actuating part 245, achieving steering or limiting functions. Specifically, when the steering block 233 abuts against the limiting part 243, a V-shaped structure on one of the opposite sides of the third group can be engaged with the end of the groove near the second actuating part 245 to form a limiting part 243, thereby achieving the limiting effect when the steering block 233 abuts against the limiting part 243. It is understood that this application does not limit the specific shape and structure of the steering block 233, as long as it can satisfy the function of the embodiments of this application.

[0136] like Figure 12 As shown, in some possible embodiments provided in this application, the outer shell portion 232 is provided with a first guide opening. The rotating shell 230 also includes an outer shell body 235 detachably connected to the outer shell portion 232. The outer shell body 235 is provided with a second guide opening corresponding to the first guide opening. The first guide opening and the second guide opening together form a guide groove 234, through which the cleaning component 100 extends out of the rotating shell 230. That is, one end of the cleaning component 100 is disposed in the guide groove 234 and connected to the lifting component 240, and the other end of the cleaning component 100 extends out of the rotating shell 230 through the guide groove 234. The provision of the guide groove 234 allows the cleaning component 100 to pass through the guide groove 234, with one end of the cleaning component 100 connected to the lifting component 240 inside the rotating shell 230, and the other end of the cleaning component 100 extending out of the rotating shell 230 through the guide groove 234, facilitating contact with the surface to be cleaned. It is understandable that at least part of the cleaning component 100 can be stored inside the rotating shell 230 through the guide groove 234, or extend outside the rotating shell 230.

[0137] like Figure 12As shown, in some possible embodiments provided in this application, the first guide opening of the outer shell 232 and the second guide opening of the outer shell 235 form a guide groove 234. Thus, the outer shell 232 and the outer shell 235 can be disassembled and separated, and the cleaning component 100 can be disassembled, assembled, and repaired, thereby improving the disassembly and assembly efficiency and repair efficiency of the cleaning component 100.

[0138] The outer shell portion 232 and the outer shell body 235 can be distributed vertically, such as the outer shell body 235 being located above the outer shell portion 232. The outer shell portion 232 and the outer shell body 235 can be detachably connected by at least one of the following structures: screw structure, snap-fit ​​structure, plug-in structure, tenon and mortise structure, and magnetic structure.

[0139] like Figure 22 As shown, in some possible embodiments provided in this application, the drive assembly 200 further includes a friction element 250 disposed between the fixed frame 210 and the lifting component 240 to dampen the movement of the lifting component 240. The lifting component 240 is dampedly connected to the fixed frame 210 by mounting the friction element 250, which facilitates adjustment of the friction coefficient of the contact surface between the lifting component 240 and the fixed frame 210, and facilitates maintenance and replacement when the friction element 250 is damaged. The friction element 250 can be sheet-shaped, strip-shaped, or ring-shaped.

[0140] Furthermore, the friction component 250 is connected to the lifting component 240. For example, after the friction component 250 and the lifting component 240 are fixed by adhesive, bolt structure, plug structure, tenon structure, etc., the friction component 250 and the lifting component 240 can be regarded as a moving whole. By setting the second limiting part 241 on the friction component 250, it can be understood that the second limiting part 241 is indirectly set on the lifting component 240. It has no impact on the limiting function of the second limiting part 241 and the first limiting part 211. At the same time, since the second limiting part 241 is set on the friction component 250, it is convenient to process and easy to implement, and it can simplify the setting of some structures of the lifting component 240, which is conducive to reducing the manufacturing cost of the lifting component 240.

[0141] like Figure 3 , Figure 5 , Figure 9 , Figure 22As shown, in some possible embodiments provided in this application, the fixing frame 210 includes a base 212 and a boss 213 disposed on the base 212. The friction member 250 has a first through hole 252, that is, the friction member 250 is an annular structure. The boss 213 passes through the first through hole 252, that is, the friction member 250 is sleeved on the outer periphery of the boss 213. At least one protrusion 251 is provided on the inner wall of the first through hole 252. The protrusion 251 is dampedly connected to the outer periphery of the boss 213. The friction member 250 is mounted on the lifting member 240. In this way, when the lifting member 240 rotates, it drives the friction member 250 to rotate synchronously with the lifting member 240. The protrusion 251 of the friction member 250 is dampedly connected to the outer periphery of the boss 213, applying a force to the relative motion of the two, so that there is a speed difference between the rotation speed of the lifting member 240 and the rotation speed of the rotating shell 230.

[0142] In some possible embodiments provided in this application, a second through hole is provided on the boss 213, and the output shaft 221 of the power assembly 220 is connected to the rotating housing 230 through the second through hole, so that the power assembly 220 can drive the rotating housing 230 to rotate synchronously. Specifically, as shown in the following embodiments... Figure 3 As shown, the rotating housing 230 and the output shaft 221 can be detachably connected via a fastener 300 to facilitate the assembly and disassembly of the rotating housing 230 and the output shaft 221. It is understood that the fastener 300 can be a bolt; in other examples, the rotating housing 230 and the output shaft 221 can be connected via at least one of a tenon-and-mortise structure, a magnetic structure, or a snap-fit ​​structure.

[0143] This application also provides a cleaning device, including a device body and a cleaning module as described in any of the foregoing embodiments, the cleaning module being disposed on the device body. For example, a mounting bracket 210 for the cleaning module is connected to the device body to connect the cleaning module to the device body. The cleaning device provided in this application has the same beneficial effects as the aforementioned cleaning module.

[0144] Based on the relevant structures of the above embodiments, the working process of the cleaning module will be explained by way of example.

[0145] When the cleaning equipment is not performing cleaning operations, the cleaning component 100 is in a non-cleaning state detached from the surface to be cleaned, and the lifting component 240 can be in the fourth position. At this time, at least a part of the cleaning component 100 is brought into the rotating shell 230.

[0146] like Figure 2 and Figure 3As shown, when the cleaning equipment needs to perform a cleaning operation, the output shaft 221 of the power component 220 rotates in the first direction (clockwise as an example), driving the rotating shell 230 to rotate in the first direction. The lifting component 240 descends to the first position under the influence of the rotating shell 230, and the cleaning component 100 contacts the surface to be cleaned. The lifting component 240 continues to rotate in the first direction, thus completing the cleaning operation. During the descent of the lifting component 240, it stops rotating under the action of the friction component (or the rotational speed of the lifting component 240 is lower than the rotational speed of the rotating shell 230). This speed difference is used to rotate and drive the cleaning component 100 out of the rotating shell 230 until it contacts the surface to be cleaned. When the lifting component 240 reaches the bottom surface, that is, descends to the first position, one end of the spiral groove 2421 on the cylinder 242 of the lifting component 240 abuts against the protrusion 2311 of the rotating shell 230. The first locking part 2422 locks the lifting component 240 and the rotating shell 230. The lifting component 240 and the rotating shell 230 rotate synchronously. The lifting component 240 continues to rotate in the first direction, so that the cleaning component 100 achieves the cleaning effect. At this time, the distance between the free end 121 of the cleaning component 100 and the rotation center of the cleaning component 100 is the first distance, which has a first cleaning range.

[0147] The rotating housing 230 is rotatably connected to a steering block 233, and the lifting member 240 is provided with a first actuating part 244. When the rotating housing 230 rotates in a first direction, it drives the steering block 233 to rotate circumferentially. During the descent of the lifting member 240, the first actuating part 244 on the lifting member 240 contacts the steering block 233, causing the steering block 233 to turn. This can be achieved by reducing the relative angle of inclination of the steering block 233 (e.g., ...). Figure 13 As shown, the steering lever 233 is in the first position. When the rotating housing 230 descends to the first position, the rotating housing 230 will drive the steering lever 233 to collide with the first actuating part 244, so that the steering lever 233 rotates to a specified angle (e.g., Figure 14 As shown, the steering lever 233 is in the second posture. Simultaneously, during the synchronous rotation of the rotating housing 230 and the lifting component 240 along the first direction, the rotational connection point of the first section 110 and the second section 120 of the cleaning component 100, under the action of the lifting component 240 and inertia, causes the free end 121 of the cleaning component 100 to point towards the rotation center of the cleaning component 100, achieving normal cleaning. At this time, as... Figure 2 As shown, the distance between the free end 121 of the cleaning component 100 and the rotation center of the cleaning component 100 is the first distance H1.

[0148] When the environmental information captured by the cleaning equipment's sensors includes information related to corners, it indicates that the cleaning equipment has moved to a corner of the room or a wall junction, and the cleaning component 100, with its initial cleaning range, is unable to thoroughly clean the corner area. Therefore, as... Figure 4 and Figure 5 As shown, the output shaft 221 of the power assembly 220 rotates in the second direction (taking counterclockwise as an example), causing the rotating housing 230 to rotate in the second direction. At the same time, the steering block 233 installed on the rotating housing 230 will also slide and collide with the limiting part 243 provided on the lifting component 240 (e.g., Figure 15 As shown, the steering lever 233 is in the third posture), causing the steering lever 233 to rotate to a specified angle and abut against the limiting part 243 on the lifting member 240 (as shown). Figure 16 As shown, the steering lever 233 is in the fourth posture, locking the lifting component 240 and the rotating shell 230, achieving synchronous rotation of the two in the second direction. During the synchronous rotation of the rotating shell 230 and the lifting component 240 in the second direction, the rotation connection point of the first section 110 and the second section 120 of the cleaning component 100, under the action of the lifting component 240 and inertia, causes the free end 121 of the cleaning component 100 to point away from the rotation center of the cleaning component 100, achieving the purpose of normal cleaning, so as to clean the corners of the room. At this time, as Figure 4 As shown, the distance between the free end 121 of the cleaning component 100 and the rotation center of the cleaning component 100 is the second distance H2, which increases the cleaning area.

[0149] When the rotating housing 230 and the lifting component 240 rotate synchronously in the second direction for a preset time to complete the cleaning of the corners of the room, the output shaft 221 of the power component 220 rotates in the first direction (taking clockwise as an example), driving the rotating housing 230 to rotate in the first direction. At the same time, the steering block 233 installed on the rotating housing 230 will also contact the first actuating part 244 provided on the lifting component 240 (e.g., Figure 17 As shown, the steering block 233 is in the fifth posture) and slides against the first actuating part 244 provided on the lifting member 240, causing the steering block 233 to rotate to a specified angle (e.g., Figure 18As shown, the steering block 233 is in the sixth posture to ensure that the angle of the steering block 233 will not hinder the subsequent rotation of the rotating shell 230 to the third position in the second direction. When the lifting member 240 descends to the first position, one end of the spiral groove 2421 on the cylinder 242 of the lifting member 240 abuts against the protrusion 2311 of the rotating shell 230, and the first locking part 2422 locks the lifting member 240 and the rotating shell 230. The lifting member 240 and the rotating shell 230 rotate synchronously to achieve the purpose of synchronous rotation in the first direction for cleaning. During the synchronous rotation of the rotating shell 230 and the lifting member 240 in the first direction, the rotation connection point of the first section 110 and the second section 120 of the cleaning member 100 is caused by the lifting member 240 and inertia, and the free end 121 of the cleaning member 100 points to the rotation center of the cleaning member 100 to achieve the purpose of normal cleaning. At this time, the distance between the free end 121 of the cleaning member 100 and the rotation center of the cleaning member 100 is the first distance.

[0150] When the cleaning equipment does not need to perform cleaning operations, based on the lifting component 240 being in the aforementioned first position, the output shaft 221 of the power component 220 rotates in the second direction (taking counterclockwise as an example), causing the rotating housing 230 to rotate in the second direction. Simultaneously, the steering block 233 mounted on the rotating housing 230 also slides and contacts the limiting part 243 provided on the lifting component 240 (e.g., ...). Figure 19 As shown, the steering lever 233 is in the seventh posture), and it impacts the limiting part 243 provided on the lifting component 240, causing the steering lever 233 to rotate to a specified angle (e.g., Figure 20As shown, the steering lever 233 is in the eighth posture, allowing the lifting member 240 and the rotating shell 230 to rotate relative to each other within a specified angle. During the relative rotation, since the rotating shell 230 and the lifting member 240 are spirally connected, and a friction element 250 is provided between the lifting member 240 and the fixed frame 210, the rotation of the rotating shell 230 will drive the lifting member 240 to rise. When the lifting member 240 rises to the third position, the first limiting part 211 on the fixed frame 210 and the second limiting part 241 on the lifting member 240 abut, limiting the circumferential rotation of the lifting member 240. At this time, as the rotating shell 230 continues to rotate in the second direction, the lifting member 240 can move relative to the rotating shell 230 at a straight angle. The cleaning component 100 rises linearly along the rotation axis of the rotating housing 230, thereby causing the cleaning component 100 to rise linearly relative to the rotating housing 230 along the rotation axis of the rotating housing 230. Since the cleaning component 100 is a soft component, the continued rotation of the rotating housing 230 forces the cleaning component 100 to deform within the guide groove 234 of the rotating housing 230, so that at least a portion of the cleaning component 100 is drawn into the rotating housing 230, thus detaching it from the surface to be cleaned. When the deformation limit is reached, the power component 220 stalls and stops working. At this time, the cleaning component 100 is in a non-cleaning state detached from the surface to be cleaned, the lifting component 240 is in the fourth position, the steering block 233 abuts against the second actuating part 245 on the lifting component 240, and is in the ninth posture (e.g. Figure 21 As shown, the steering lever 233 is in the ninth posture, which can also be understood as the initial posture of the steering lever 233, thus completing a cycle.
