[0037] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0038] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0039] Current cleaning equipment typically uses a rotating or reciprocating motion of the cleaning module to clean stains on the floor. While this method is effective for cleaning ordinary stains, the unidirectional movement of the rotating or reciprocating motion makes it difficult for current cleaning equipment to effectively remove stubborn stains.

[0040] In view of the above-mentioned technical problems, this application provides a cleaning module and a cleaning device, which aims to improve the cleaning effect of the cleaning device and can clean stubborn stains such as dried stains and heavy oil stains.

[0041] Specific technical solutions will now be described in detail with reference to the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different figures. The use of similar or identical reference numerals in different figures does not mean that all figures including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this application in a generalized, illustrative, and not restrictive manner.

[0042] Figure 1 is a schematic diagram of the structure of a cleaning device 1000 according to an embodiment of this application. Referring to Figure 1, the cleaning device 1000 can be a sweeping robot, a floor scrubber, etc. The cleaning device 1000 includes a main unit 200 and a cleaning module 100 installed on the main unit 200. The main unit 200 is equipped with a walking device 300, capable of automatic movement or being pushed by the user to move on the surface to be cleaned (e.g., floor, step, table, etc.). For ease of description, the direction of movement of the cleaning device 1000 is defined as the X direction. A rotating brush 400 may also be configured on the main unit 200 to clean larger debris. The cleaning module 100 is provided with a cleaning component 110. The cleaning module 100 is installed on the main unit 200, and at least the cleaning component 110 extends beyond the outside of the main unit 200; for example, at least a portion of the cleaning component 110 is located at the bottom of the main unit 200 and exposed to the outside. The cleaning component 110 can come into contact with the surface to be cleaned, and the cleaning component 110 moves relative to the surface to be cleaned, thereby wiping away the stains on the surface to be cleaned.

[0043] The movement of the cleaning component 110 relative to the surface to be cleaned directly affects the cleaning effect of the cleaning device 1000. In the cleaning module 100 provided in the first aspect embodiment of this application, the cleaning component 110 can move in different directions relative to the surface to be cleaned, effectively removing stubborn stains from the surface. The cleaning module 100 provided in the first aspect embodiment of this application will be described in detail below with reference to the accompanying drawings.

[0044] Please refer to Figure 2, which shows a schematic diagram of the structure of a cleaning module 100 according to an embodiment of this application. The cleaning module 100 includes a drive member 140, a vibrating member 120, and a cleaning member 110. The drive member 140 has an output shaft 141 for outputting rotational power, and the vibrating member 120 is rotatably connected to the output shaft 141 in an eccentric manner relative to the axis of rotation A of the output shaft 141. That is, the torque output by the output shaft 141 is not transmitted to the vibrating member 120, and the vibrating member 120 itself does not rotate actively and its posture remains unchanged. Because the power input point of the vibrating member 120 is eccentrically positioned relative to the axis of rotation A of the output shaft 141, when the output shaft 141 rotates around its own axis, the vibrating member 120, eccentrically positioned relative to the output shaft 141, will perform planar rotary vibration about the axis of rotation A of the output shaft 141. It is understandable that the plane of the rotary vibration element 120, which performs planar rotary vibration, cannot be interpreted restrictively as a horizontal plane, but should be understood as a plane perpendicular to the rotation axis A of the output shaft 141. When the rotation axis A of the output shaft 141 is set vertically, the rotary vibration element 120 rotates on the horizontal plane accordingly.

[0045] The radius of the planar gyroscopic vibration of the vibrating element 120 is the eccentricity between the vibrating element 120 and the output shaft 141, which is the distance between the power input point of the vibrating element 120 and the rotation axis A of the output shaft 141. Each point on the vibrating element 120 undergoes planar gyroscopic vibration with the eccentricity as the radius. The trajectory of each point on the vibrating element 120 is circular, but the rotation center of the planar gyroscopic vibration of each point on the vibrating element 120 is different. For ease of description, the motion mode of the vibrating element 120, "not rotating itself, but undergoing planar gyroscopic vibration as a whole," is defined as gyroscopic vibration.

[0046] When the vibrating element 120 performs planar rotary vibration, its position on the plane perpendicular to the output shaft 141 (rotation shaft A) changes, and the direction of position change can be any direction on that plane, thus generating vibration through rapid planar rotary vibration. The cleaning element 110 is connected to the vibrating element 120. The cleaning element 110 vibrates in different directions along with the rapid planar rotary vibration of the vibrating element 120. When the cleaning element 110 contacts the surface to be cleaned, it vibrates in different directions relative to the surface, disturbing the stains on the surface in different directions and accelerating the separation of stains from their attachment. This allows for faster and more efficient stain cleaning, and it also has a good cleaning effect on dried stains, heavy oil stains, and other stubborn stains. Compared to conventional rotation or reciprocating motion, which is unidirectional and disturbs stains in a unidirectional direction, the cleaning effect on stubborn stains is weaker. The cleaning module 100 provided in this application can agitate stains from different directions, thereby achieving a better cleaning effect.

[0047] A cleaning module according to one or more embodiments of this application includes a drive unit, a rotating vibrator, and a cleaning unit. The output shaft of the drive unit outputs rotational power, and the rotating vibrator is rotatably connected to the output shaft in a manner eccentric to the output shaft's axis of rotation. Because the power input point of the rotating vibrator is eccentrically positioned relative to the output shaft's axis of rotation, when the output shaft rotates about its own axis, the rotating vibrator, eccentrically positioned relative to the output shaft, will perform planar rotary vibration about the output shaft's axis of rotation. Furthermore, because the rotating vibrator is rotatably connected to the output shaft, its own posture remains unchanged while performing planar rotary vibration; the rotating vibrator does not rotate. Thus, vibration is generated through rapid planar rotary vibration, and the direction of this vibration can be any direction in a plane perpendicular to the output shaft's axis of rotation. The cleaning component is connected to the vibrating component. As the vibrating component performs rapid planar rotational vibration, it generates vibrations in different directions. When the cleaning component comes into contact with the surface to be cleaned, it vibrates in different directions relative to the surface to be cleaned, thus cleaning the surface. It can remove stubborn stains such as dried stains and heavy oil stains, improving the cleaning effect. Therefore, the cleaning equipment equipped with this cleaning module can meet different cleaning needs.

[0048] Referring to Figure 2, in some embodiments, to facilitate the installation of the cleaning module 100, the cleaning module 100 also includes a fixing bracket 130. The fixing bracket 130 serves as a support base for mounting the drive component 140 and the vibrating component 120. The entire cleaning module 100 is connected to the main unit 200 of the cleaning equipment 1000 via the fixing bracket 130.

[0049] Please refer to Figures 3 and 4, which show a bottom view and a front view of the cleaning module 100 according to an embodiment of this application. In this embodiment, the vibrating element 120 includes a first vibrating part 121 and a second vibrating part 122 spaced apart. Both the first vibrating part 121 and the second vibrating part 122 are provided with cleaning elements 110, which can be cleaning cloths, bristles, brushes, etc. The cleaning elements 110 on the first vibrating part 121 and the second vibrating part 122 can be an integral cleaning element or two independent cleaning elements; this application does not impose any limitations.

[0050] In some embodiments, to ensure cleaning effectiveness, the cleaning components 110 should all be parallel to the ground, tabletop, or other surfaces to be cleaned. Correspondingly, the motion planes of the first and second vibrating parts 121 and 122 are also parallel to the surfaces to be cleaned, and the rotating shaft A extends vertically. For ease of description, the extension direction of the rotating shaft A of the output shaft 141 is defined as the Z-direction, as shown in Figure 4. In some embodiments, both the first and second vibrating parts 121 and 122 are parallel to the fixed bracket 130, meaning the fixed bracket 130 is also parallel to the surfaces to be cleaned. A certain gap should exist between any two of the first vibrating part 121, the second vibrating part 122, and the fixed bracket 130. This gap includes a gap c in the direction of the motion plane (as shown in Figure 3) and a gap d perpendicular to the motion plane (gap d is along the Z-direction, as shown in Figure 4), to prevent interference with the movement of the first and second vibrating parts 121 and 122. Furthermore, the gap d can also prevent the first rotating part 121 and the second rotating part 122 from colliding with each other or with the fixed bracket 130 during rotation, thus preventing noise.

[0051] The first rotating part 121 and the second rotating part 122 can be located on the same plane, in which case a sufficient gap should be provided between them. The first rotating part 121 and the second rotating part 122 can also be located on different planes. If the first rotating part 121 and the second rotating part 122 have a height difference and do not overlap in the height direction, then the projections of the first rotating part 121 and the second rotating part 122 on the plane of motion can overlap.

[0052] Please refer to Figures 5, 5A, and 6, which respectively show a structural schematic diagram, a cross-sectional view, and a motion trajectory diagram of the rotary vibrator 120 eccentrically positioned relative to the output shaft 141 in a cleaning module 100 according to an embodiment of this application. The first rotary vibrator 121 and the second rotary vibrator 122 are each rotatably connected to the output shaft 141 in a manner eccentrically positioned relative to the axis of rotation A of the output shaft 141. Therefore, both the first rotary vibrator 121 and the second rotary vibrator 122 can perform planar rotary vibration with the axis of rotation A of the output shaft 141 as the axis. The motion trajectory generated by the planar rotary vibration of the first rotary vibrator 121 and the second rotary vibrator 122 is shown in Figure 6.

[0053] Referring to Figures 5A and 6, each point on the first rotary vibration section 121 undergoes planar rotary vibration with an eccentricity a1 as the radius, and each point on the second rotary vibration section 122 undergoes planar rotary vibration with an eccentricity a2 as the radius. The interval c between the first rotary vibration section 121 and the second rotary vibration section 122 should at least ensure that the first rotary vibration section 121 and the second rotary vibration section 122 do not collide during their rotary vibrations. Since both the first rotary vibration section 121 and the second rotary vibration section 122 only undergo planar rotary vibration and do not rotate themselves, the required motion space is small, which is beneficial for the miniaturization of the cleaning equipment. The maximum distance between the farthest end of this motion space and the current position of the first rotary vibration section 121 and the second rotary vibration section 122 is the diameter of the eccentric circle, that is, twice the eccentricity. In other words, by setting the interval c to be greater than twice the eccentricity, collisions between the first rotary vibration section 121 and the second rotary vibration section 122 can be avoided.

[0054] In some embodiments, the first vibrating part 121 and the second vibrating part 122 have different motion trajectories. That is, the first vibrating part 121 and the second vibrating part 1222 have relative motion, and the first vibrating part 121 and the second vibrating part 122 can generate disturbances to the stains in different directions, further improving the cleaning effect. The different motion trajectories of the first vibrating part 121 and the second vibrating part 122 can be achieved by setting different eccentricities and / or different phases between them.

[0055] In some embodiments, the first vibrating section 121 and the second vibrating section 122 may be configured to have a phase difference. That is, the phase angle of the first vibrating section 121 relative to the output shaft 141 is different from the phase angle of the second vibrating section 122 relative to the output shaft 141. Referring to Figures 5A and 6A, in some embodiments, the phase difference between the first vibrating section 121 and the second vibrating section 122 is 180°. That is, the line connecting the power input point N of the first vibrating section 121 and the power input point M of the second vibrating section 122 passes through the rotation axis A of the output shaft 141 (point O represents the intersection of the rotation axis A and the motion plane of the first vibrating section 121 and the second vibrating section 122).

[0056] Taking the output shaft 141 rotating in the direction indicated by the arrow in Figure 6A as an example, both the first rotating section 121 and the second rotating section 122 undergo planar rotary vibration in the direction indicated by the arrow. At the current moment, the power input point N of the first rotating section 121 moves downwards, while the power input point M of the second rotating section 122 moves upwards; their directions of motion are opposite. By setting the phase difference between the first rotating section 121 and the second rotating section 122 to 180°, a portion of the eccentric force during rotation can cancel each other out, reducing rotational noise and vibration transmitted from the first rotating section 121 and the second rotating section 122 to the fixed bracket 130. Furthermore, since the directions of motion of the first rotating section 121 and the second rotating section 122 are opposite at any given moment, the cleaning effect can be further improved.

[0057] Referring to Figures 5A and 6A, in some embodiments, both the first vibrating section 121 and the second vibrating section 122 may be eccentrically positioned relative to the rotation axis A of the output shaft 141, but the eccentricity a1 and a2 of the first vibrating section 121 may differ. The eccentricity can be set according to the shape and position of the first vibrating section 121 and the second vibrating section 122, as well as the material and type of the cleaning component 110 to which they are connected. It is understood that the larger the eccentricity, the larger the amplitude of the vibration when the cleaning component 120 performs rotational vibration.

[0058] Referring to Figure 7, in some embodiments, the first rotating part 121 is closer to the center of the main unit 200 of the cleaning device 1000 than the second rotating part 122. That is, the projection of the first rotating part 121 on the motion plane is closer to the center of the main unit 200 of the cleaning device 1000 than the projection of the second rotating part 122 on the motion plane, and the second rotating part 122 is closer to the edge of the main unit 200 of the cleaning device 1000.

[0059] Therefore, in some embodiments, the eccentricity a1 of the first rotating part 121 relative to the rotating shaft A can be further set to be not less than the eccentricity a2 of the second rotating part 122 relative to the rotating shaft A, i.e., a1≥a2. The first rotating part 121 has a larger eccentricity value. Combined with the foregoing, the larger the radius of the planar rotary vibration of the first rotating part 121, the larger the amplitude of the rotation, and the better the cleaning effect of the cleaning component 110 connected to the first rotating part 121. The second rotating part 122 has a smaller amplitude of rotation, resulting in relatively lighter water stains, and the mopping effect of the cleaning component 110 connected to the second rotating part 122 is better.

[0060] Figure 8 shows a schematic diagram of the structure of the cleaning component 110 in one embodiment of this application. Referring to Figure 8, in this embodiment, the cleaning component 110 includes a first cleaning part 111 and a second cleaning part 112 disposed at intervals. The first cleaning part 111 is connected to the first rotating part 121, and the second cleaning part 112 is connected to the second rotating part 122. The type or material of the first cleaning part 111 and the second cleaning part 112 may be the same or different, and this application does not impose any restrictions.

[0061] Referring to Figures 7 and 8, in some embodiments, the first cleaning part 111 and the second cleaning part 112 are respectively disposed on the side of the first vibrating part 121 and the second vibrating part 122 away from the driving member 140, so that the driving member 140 is closer to the main unit 200 of the cleaning device 1000, and the first cleaning part 111 and the second cleaning part 112 are exposed. To improve the cleaning effect, the first cleaning part 111 and the second cleaning part 112 are coplanar, specifically, the side that contacts the surface to be cleaned is coplanar.

[0062] Referring to Figure 7, in some embodiments, the projection of the first rotating part 121 on the motion plane is closer to the center of the cleaning device 1000 than the projection of the second rotating part 122 on the motion plane, and the second rotating part 122 is closer to the edge of the cleaning device 1000. Therefore, the second cleaning part 112 connected to the second rotating part 122 is also closer to the edge of the cleaning device 1000 than the first cleaning part 111, and the second cleaning part 112 is located outside the first cleaning part 111.

[0063] When the cleaning module 100 is in operation, the first cleaning section 111 vibrates relative to the surface to be cleaned, quickly wiping away stains. Some stains may not separate from the surface, or although they may separate, they may not adhere to the first cleaning section 111. The second cleaning section 112, located outside the first cleaning section 111, can wipe away residual stains and water stains generated during the cleaning process of the first cleaning section 111 from the surface to be cleaned during its vibration, improving the cleaning effect. Along the travel direction of the cleaning device 1000, the second cleaning section 112 is located behind the first cleaning section 111. The first cleaning section 111 first cleans the surface to be cleaned, and then the second cleaning section 112 mops the cleaned area, realizing a "wash first, then mop" cleaning mode.

[0064] Therefore, in some embodiments, the first cleaning part 111 can use a material with a rougher surface and greater friction, such as a brush, to efficiently scrape away stains; the second cleaning part 112 can use a material with a finer surface and better water absorption, such as a brush, to wipe away water stains and residual stains. In some embodiments, the eccentricity a1 of the first rotating part 121 can be further set to be greater than the eccentricity a2 of the second rotating part 122, for example, a1 is 3mm and a2 is 1mm. The larger eccentricity of the first rotating part 121, combined with the foregoing, the larger the radius of the planar rotary vibration of the first rotating part 121, the larger the amplitude of the vibration, thus improving the cleaning effect of the first cleaning part 111. The smaller amplitude of the second rotating part 122 results in lighter water stains and better mopping effect, achieving efficient cleaning in conjunction with the "wash first, mop later" cleaning mode.

[0065] To avoid interference between the first cleaning section 111 and the second cleaning section 112, they are also spaced apart. Referring to Figures 7 and 8, in some embodiments, the cleaning component 110 further includes a flexible component 113, which connects the first cleaning section 111 and the second cleaning section 112, allowing them to form a single unit during installation for ease of assembly. The flexible component 113 can be made of elastic rope, flexible cloth, or other similar materials; this application does not impose any limitations. Furthermore, in some embodiments, the flexible component 113 is made of flexible cloth, which covers the gap between the first cleaning section 111 and the second cleaning section 112, preventing foreign objects from entering between the first cleaning section 111 and the second cleaning section 112, or even inside the cleaning module 100, during operation.

[0066] Referring to Figures 7 and 8, in some embodiments, the cleaning module 100 further includes a threading wire 153 for mounting wire harnesses and conduits. The threading wire 153 is mounted on the second vibrating section 122, and a fixing groove for fixing the threading wire 153 can be provided on the second vibrating section 122. The flexible member 113 connects the first cleaning section 111, the second cleaning section 112, and the threading wire 153. The flexible member 113 is connected around the outer periphery of the first cleaning section 111, and the outer periphery of the flexible member 113 connects the second cleaning section 112 and the threading wire 153. The second cleaning section 112 and the threading wire 153 enclose both the flexible member 113 and the first cleaning section 111 within the flexible member 113.

[0067] The specific shape and quantity of the first cleaning unit 111 and the second cleaning unit 112 can be determined according to the shape and size of the cleaning equipment 1000 to which they are installed. For example, the specific shape of the first cleaning unit 111 and the second cleaning unit 112 can be a long strip, a rectangle, an arc, a circle, etc., and this application does not impose any restrictions.

[0068] Taking the most common round robotic vacuum cleaner on the market as an example, the cleaning module 100 is located at the rear of the main unit 200 of the robotic vacuum cleaner, occupying an area smaller than a semi-circular region, as shown in Figure 7. The outer edge of the second cleaning part 112 coincides with the outer contour of the robotic vacuum cleaner, and the second cleaning part 112 is C-shaped. The first cleaning part 111 is D-shaped, and the C-shaped second cleaning part 112 semi-encloses the D-shaped first cleaning part 111, as shown in Figure 8.

[0069] In some embodiments, the second rotating part 122 is located between the fixed bracket 130 and the first rotating part 121, and the projection of the first rotating part 121 along the rotation axis A is located in the projection of the second rotating part 122 along the rotation axis A. This ensures that both the first rotating part 121 and the second rotating part 122 are driven by a single output shaft 141, and also facilitates the installation of the first rotating part 121 and the second rotating part 122.

[0070] The specific structures of the first vibrating section 121 and the second vibrating section 122 can be plates or brackets, as long as they meet the installation requirements of the cleaning components; this application does not impose any limitations. Figures 9 and 10 respectively show schematic diagrams of the structures of the second vibrating section 122 and the first vibrating section 121 in some embodiments. Referring to Figure 9, the second vibrating section 122 includes a second vibrating plate 1221 and a second active eccentric shaft 1222. The second active eccentric shaft 1222 is connected to the output shaft 141 in a manner eccentric relative to the rotation axis A of the output shaft 141, and the second active eccentric shaft 1222 is directly connected to the output shaft 141. The second active eccentric shaft 1222 is rotatably engaged with at least one of the second vibrating plate 1221 and the output shaft 141; that is, at least one end of the second active eccentric shaft 1222 is rotatably engaged with the connected parts, thereby achieving the rotatable engagement between the second vibrating section 122 and the output shaft 141.

[0071] Referring to Figure 10, the first rotating vibration unit 121 includes a first rotating vibration plate 1211 and a first active eccentric shaft 1212. The first active eccentric shaft 1212 is connected to a second active eccentric shaft 1222 in a manner eccentric to the rotation axis relative to the output shaft 141. The first active eccentric shaft 1212 is dynamically coupled to the output shaft 141 through the second active eccentric shaft 1222. The first active eccentric shaft 1212 is rotatably engaged with at least one of the first rotating vibration plate 1211 and the second active eccentric shaft 1222. That is, at least one end of the first active eccentric shaft 1212 is rotatably engaged with a connected component, thereby achieving the rotatable engagement between the first rotating vibration unit 121 and the output shaft 141.

[0072] In other embodiments, two eccentric shafts can be provided on the output shaft 141. One end of each eccentric shaft is connected to the output shaft 141, and the other end is connected to the first oscillating part 121 and the second oscillating part 122 respectively. Then, at least one end of the eccentric shaft is rotatably connected to the connected parts, thereby realizing the rotatable connection between the oscillating part 120 and the output shaft 141.

[0073] To achieve a larger cleaning area, the cleaning module 100 requires a larger area for the first cleaning section 111 and the second cleaning section 112. To ensure stable installation of the first cleaning section 111 and the second cleaning section 112, the vibrating element 120 should also have a large mounting surface. Clearly, the area of ​​the vibrating element 120 is much larger than the output shaft 141. Single-point fixing may lead to instability during movement of the vibrating element 120, or even noise. Therefore, referring to Figure 11, in some embodiments, the fixed bracket 130 is provided with at least one auxiliary hanging point shaft 131. The auxiliary hanging point shaft 131 is rotatably connected to the fixed bracket 130 and simulates the function of the output shaft 141, but does not output power. Since both the output shaft 141 and the auxiliary hanging point shaft 131 rotate, to improve rotational stability, in some embodiments, bearings 132 are fitted onto both the output shaft 141 and the auxiliary hanging point shaft 131. The outer ring of the bearing 132 is connected to the fixed bracket 130. Referring to Figure 11, in some embodiments, the auxiliary mounting point shaft 131 and its bearing 132 are fixed to the fixed bracket 130 by a mounting bracket 133. The fixed bracket 130 has a through hole for the output shaft 141 and the auxiliary mounting point shaft 131 to pass through.

[0074] Referring to Figure 11, in some embodiments, vibration damping components 152 are provided at the mounting points of both the output shaft 141 and the auxiliary mounting point shaft 131. The vibration damping components 152 are made of flexible, elastically deformable materials, such as rubber or silicone. The vibration damping components 152 ensure flexible connections between the output shaft 141 and the fixed bracket 130, as well as between the auxiliary mounting point shaft 131 and the fixed bracket 130, thereby reducing vibration transmission and thus noise.

[0075] Referring to Figures 12 and 13, the second rotary vibration unit 122 further includes at least one second driven eccentric shaft 1223, which is connected to the auxiliary hanging point shaft 131 in a manner eccentric to the shaft of rotation relative to the auxiliary hanging point shaft 131, and the second driven eccentric shaft 1223 is rotatably engaged with the second rotary vibration plate 1221 and / or the auxiliary hanging point shaft 131; the first rotary vibration unit 121 further includes at least one first driven eccentric shaft 1213, which is connected to the second driven eccentric shaft 1223 in a manner eccentric to the shaft of rotation relative to the auxiliary hanging point shaft 131, and the first driven eccentric shaft 1213 is rotatably engaged with the first rotary vibration plate 1211 and / or the second driven eccentric shaft 1223.

[0076] It is understandable that the driven eccentric shafts 1213 and 1223 have the same function as the driving eccentric shafts 1212 and 1222 but do not transmit power. The eccentricity b between the driven eccentric shafts 1213 and 1223 and the auxiliary mounting point shaft 131 is equal to the eccentricity a between the corresponding driving eccentric shafts 1212 and 1222 and the output shaft 141, as shown in Figure 13. That is, the eccentricity b2 of the second driven eccentric shaft 1223 relative to the axis of the auxiliary mounting point shaft 131 is equal to the eccentricity a2 of the second driving eccentric shaft 1222 relative to the axis A of the output shaft 141, and the eccentricity b1 of the first driven eccentric shaft 1213 relative to the axis of the auxiliary mounting point shaft 131 is equal to the eccentricity a1 of the first driving eccentric shaft 1212 relative to the axis A of the output shaft 141. By setting driven eccentric shafts 1213 and 1223 and auxiliary hanging point shaft 131, both the first rotary vibration part 121 and the second rotary vibration part 122 have multiple fixed points. The multiple fixed points ensure that the first rotary vibration part 121 and the second rotary vibration part 122 move smoothly.

[0077] In other embodiments, the driven eccentric shaft can also be used as part of the auxiliary hanging point shaft 131. One end of the driven eccentric shaft is connected to the auxiliary hanging point shaft 131, and the other end is connected to the corresponding rotating vibration part. Then, at least one end of the driven eccentric shaft is rotatably connected to the connected part, thereby realizing the rotatable connection between the corresponding rotating vibration part and the auxiliary hanging point shaft 131.

[0078] To further reduce noise during the movement of the vibrating element 120, please refer to Figures 14 and 15. In some embodiments, wear-resistant elements 151 are provided between at least two of the fixed bracket 130, the first vibrating plate 1211, and the second vibrating plate 1221. For example, if the second vibrating part 122 is located between the fixed bracket 130 and the first vibrating part 121, then wear-resistant elements 151 are provided between the second vibrating part 122 and the fixed bracket 130, and between the second vibrating part 122 and the first vibrating part 121. The provision of wear-resistant elements 151 ensures that there is a certain gap between any two of the fixed bracket 130, the first vibrating plate 1211, and the second vibrating plate 1221 in the axial direction of the rotating shaft A. The wear-resistant elements 151 can reduce collisions and noise between the two plates. Multiple wear-resistant elements 151 can be provided, with multiple wear-resistant elements 151 spaced apart, so that each pair of the fixed bracket 130, the first vibrating plate 1211, and the second vibrating plate 1221 remains parallel.

[0079] The wear-resistant part 151 is made of metal, such as plastic or rubber. It is fixed to the fixed bracket 130 and the second rotary vibrating plate 1221 by several support members 137, as shown in Figures 14 and 15. To prevent excessive friction between the wear-resistant part 151 and the rotary vibrating plate during relative movement, hindering the movement of the plate, the first rotary vibrating plate 1211 and the second rotary vibrating plate 1221 should be installed in contact with the plate but not compressed.

[0080] In other embodiments, the collision and noise between the two plates can be reduced by providing an elastic element between at least two of the fixed bracket 130, the first rotating plate 1211, and the second rotating plate 1221. The elastic element can be a silicone pad, a rubber pad, a wire spring, a metal sheet, or similar structure.

[0081] Referring to Figure 16, a structural schematic diagram of the second rotating plate 1221 in some embodiments is shown. The second rotating plate 1221 includes a rotating body 12211 and a rotating edge 12212. The rotating edge 12212 is disposed on the periphery of the rotating body 12211 and is used to mount the second cleaning part 112. To reduce the Z-axis height of the cleaning module 100, in some embodiments, the rotating body 12211 has a rotating cavity 12213 for accommodating the first rotating plate 1211. The rotating edge 12212 is connected to the rotating body 12211 and located at the periphery of the opening of the rotating cavity 12213, thereby forming a layout in which the first cleaning part 111 is inside and the second cleaning part 112 is outside. Based on the above structure of the second rotary vibrating plate 1221, wear-resistant parts 151 need to be provided between the rotary vibrating body 12211 and the fixed bracket 130, between the rotary vibrating body 12211 and the first rotary vibrating plate 1211, and between the rotary vibrating edge 12212 and the fixed bracket 130. In some embodiments, the second rotary vibrating plate 1221 is provided with a fixing groove 12214 for fixing the threaded wire, as shown in FIG16.

[0082] Please refer to Figures 17 and 18, which show a schematic diagram and an exploded view of a cleaning module 100 according to another embodiment of this application. The cleaning module 100 includes a fixed bracket 130a, a drive component 140, a vibrating component 120, and a cleaning component 110. The fixed bracket 130a serves as a support base for mounting the drive component 140 and the vibrating component 120. The entire cleaning module 100 is connected to the main unit 200 of the cleaning device 1000 via the fixed bracket 130a. The cleaning component 110 still includes a first cleaning section 111 and a second cleaning section 112 spaced apart. Other undescribed structures of the cleaning component 110 can be referred to the relevant descriptions above. The drive component 140 has an output shaft 141 for outputting rotational power. Unlike the embodiments described above, the rotating vibrator 120 includes only one rotating vibrating part 121a. The rotating vibrating part 121a is rotatably connected to the output shaft 141 in an eccentric manner relative to the axis A of the output shaft 141. The rotating vibrating part 121a performs planar rotary vibration about the axis A of the output shaft 141. The installation position of the rotating vibrating part 121a is the same as that of the first rotating vibrating part 121. More detailed information about the rotating vibrating part 121a can be found in the above description of the first rotating vibrating part 121. The first cleaning part 111 is connected to the rotating vibrating part 121a, and the second cleaning part 112 is connected to the fixed bracket 130a. The structure and installation position of the fixed bracket 130a are similar to those of the second rotating vibrating part 122, but the fixed bracket 130a is fixed and does not rotate.

[0083] Referring to Figure 19, the fixed bracket 130a includes a bracket body 134 and an extension edge 135. The bracket body 134 is used to mount the drive component 140, and the extension edge 135 is disposed on the periphery of the bracket body 134 for mounting the second cleaning part 112. The bracket body 134 has a rotary vibration cavity 12213a for accommodating the first rotary vibration part 121. The extension edge 135 is connected to the bracket body 134 and located at the periphery of the opening of the rotary vibration cavity 12213a, thereby forming a layout in which the first cleaning part 111 is inside and the second cleaning part 112 is outside.

[0084] In this embodiment, the first cleaning section 111 rotates with the rotating section 121a, while the second cleaning section 112 remains stationary relative to the fixed bracket 130a. The second cleaning section 112 is also located outside the first cleaning section 111 and behind the first cleaning section 111 along the travel direction of the cleaning device 1000. The first cleaning section 111 first cleans the surface to be cleaned, and then the second cleaning section 112 wipes the cleaned area, thus achieving the "wash first, then mop" cleaning mode.

[0085] When the cleaning module 100 is in operation, it needs to wet the ground with water. The water can be sprayed from the main unit 200 of the cleaning device 1000, spraying it in front of the first cleaning unit 111 and the second cleaning unit 112. In some embodiments, water can also be directly supplied to the first cleaning unit 111 and / or the second cleaning unit 112, so that the first cleaning unit 111 and / or the second cleaning unit 112 are wetted, thereby improving the cleaning effect.

[0086] Referring to Figure 20, the cleaning module 100 also includes at least one pump 160 and a liquid outlet 170 connected to the pump 160 via a pipe (not shown in the figure). Both the pump 160 and the pipe are mounted on a fixed bracket 130 and are used to pump liquid to the cleaning component 110. This liquid can be water, cleaning agent, or a mixture of both. The downstream end of the pipe is the liquid outlet 170, used to discharge liquid to the cleaning component 110. The liquid outlet 170 can directly contact the cleaning component 110, or a through hole can be formed in a component located below the liquid outlet 170 to allow liquid to flow to the cleaning component 110.

[0087] The cleaning module 100 shown in Figure 21 includes four liquid outlets 170, which supply liquid to different positions of the first cleaning section 111 and the second cleaning section 112, respectively. Multiple outlets ensure that the first cleaning section 111 and the second cleaning section 112 are evenly wetted. The fixed bracket 130 is provided with four fixing parts 136, and the four liquid outlets 170 are respectively mounted on the four fixing parts 136 with their openings facing downwards. In some embodiments, because a wear-resistant member 151 is provided between the fixed bracket 130 and the vibrating member 120, there is a gap between the fixed bracket 130 and the vibrating member 120. This gap can be used to arrange the liquid outlets 170, that is, the liquid outlets 170 are fixed to the surface of the fixed bracket 130 facing the vibrating member 120, as shown in Figure 21. Correspondingly, each of the vibrating components 120 is provided with a through hole through which a liquid outlet nozzle 170 passes. The nozzle 170 passes through the through hole of the vibrating component 120 and sprays liquid directly into the first cleaning section 111 and the second cleaning section 112. Considering that the vibrating component 120 needs to rotate, the through hole size should be larger than the liquid outlet nozzle 170 to avoid the liquid outlet nozzle 170 interfering with the movement of the vibrating component 120.

[0088] The pumping force of pump 160 originates from the rotation of the rotor. The rotor's operating power can come from an independently installed motor or from the drive unit 140. Essentially, the drive unit 140 simultaneously drives the vibrating element 120 to rotate and the pump 160 to operate. Referring to Figures 22 and 23, in some embodiments, the drive unit 140 includes a drive section 142, a transmission section 143, and an output shaft 141. The drive section 142 outputs rotational power and can be a motor. The transmission section 143 is power-coupled with the drive section 142 to transmit the power of the drive section 142. The transmission section 143 includes at least two output gears 1431 for outputting power. One output gear 1431 is connected to the output shaft 141 to transmit power to the vibrating element 120, causing it to rotate. At least one of the remaining output gears 1431 is connected to the pump 160 to drive the pump 160 and pump liquid to the outlet 170. In some embodiments, the transmission unit 143 may also include a plurality of transmission gears, which can perform functions such as deceleration and reversal.

[0089] In this cleaning module 100, the drive unit 142, transmission unit 143, and pump 160 all rotate, generating operating noise. In particular, the drive unit 142 and pump 160, when their axes of rotation are not collinear, will exert an eccentric force on the fixed bracket 130. Therefore, it is necessary to arrange the drive unit 142 and pump 160 coaxially, or to use multiple pumps 160 symmetrically distributed relative to the drive unit 142.

[0090] In some embodiments, the number of pumps is even, such as 2, 4, 6, etc. The even number of pumps are coaxially arranged and symmetrically distributed on both sides of the connected output gear 1431. Referring to Figure 23, the specific distribution of the pumps 160 in a cleaning module 100 in one embodiment is shown. Four pumps 160 are provided, arranged in pairs and symmetrically distributed on both sides of the connected output gear 1431. That is, the four pumps 160 are symmetrically distributed with respect to the drive unit 142 and the output gear 1431 used to drive the pump 600.

[0091] In some embodiments, four pumps 160 may be arranged coaxially, with the pumps 160 distributed on both sides of the output gear 1431 canceling out some of the eccentric force, reducing noise and vibration of the fixed bracket 130. The four pumps 160 correspond to four liquid outlets 170, and each liquid outlet 170 dispenses liquid independently.

[0092] The cleaning module 100 is mounted on the main unit 200. It can be installed inside the main unit 200, with only the first cleaning part 111 and the second cleaning part 112 exposed at the bottom of the main unit 200. Alternatively, a clearance area can be provided on one side of the main unit 200, with the entire cleaning module 100 located within this clearance area. The cleaning module 100 can be fixedly connected to the main unit 200 of the cleaning equipment 1000 via threaded fasteners, snap-fit ​​structures, etc., and the relative position of the cleaning module 100 and the main unit 200 remains unchanged after installation. It can also be movably connected to the main unit 200 of the cleaning equipment 1000 via hinges, connectors, pull ropes, etc., meaning the cleaning module 100 can move with the main unit 200 and can simultaneously rotate and / or rise and fall relative to the main unit 200.

[0093] Referring to Figure 24, in some embodiments, the cleaning module 100 includes a pulling member 190. One end of the pulling member 190 is connected to the fixed bracket 130 or the driving member 140, and the other end is used to connect to the main unit 200 of the cleaning device 1000. In some embodiments, the pulling member 190 can be driven to swing or wrap around a certain part by the driving member provided in the main unit 200; in other embodiments, the driving member 140 can also be used as the driving member for the swinging or wrapping of the pulling member 190. The driving member drives the pulling member 190 to swing or wrap around a certain part, thereby changing the length of the pulling member 190 exposed between the fixed bracket 130 and the main unit 200, thereby allowing the fixed bracket 130 and the driving member 140 to rise and fall relative to the main unit 200.

[0094] The fixed bracket 130 serves as the mounting base for the cleaning module 100. The drive unit 140 is mounted on the fixed bracket 130. The raising and lowering of the fixed bracket 130 relative to the main unit 200 is equivalent to the raising and lowering of the cleaning module 100 relative to the main unit 200. Since the cleaning equipment is always in contact with the ground through its walking mechanism, the raising and lowering of the cleaning module 100 relative to the main unit 200 manifests as a change in the overall ground clearance of the cleaning module 100. When the ground clearance of the cleaning module 100 increases, it will not interfere with obstacles, thus improving the obstacle-crossing height, escape capability, and adaptability to different road surfaces of the equipment equipped with the cleaning module 100.

[0095] In some embodiments, at least a portion of the pulling member 190 is made of a flexible material. The pulling member 190 can be a flexible cable such as a steel wire rope or nylon rope; it can also be a combination structure of a flexible cable and a rigid connector, such as a combination structure of a flexible cable and a tie rod. That is to say, the pulling member 190 is at least partially a flexible structure. Using a flexible structure as a power transmission medium can solve the spatial arrangement problem of the cleaning module 100 to a certain extent. By using some fixed pulley structures, the driving component can be arranged at any position of the cleaning equipment, thereby achieving optimal space utilization.

[0096] In some embodiments, the drive member 140 drives the tension member 190 to swing or wrap around a component, thereby changing the length of the tension member 190 exposed between the fixed bracket 130 and the main unit 200. The drive member 140 may be provided with a turntable, one end of the tension member 190 being constrained by the turntable, which rotates when the drive member 140 is running, thereby causing the tension member 190 to wrap around the turntable.

[0097] Please refer to Figure 25, which illustrates the connection structure between the pulling member 190 and the driving member 140 in some embodiments. The driving member 140 includes an output shaft 141, a driving part 142, and a one-way motion part 144, which is dynamically coupled to the driving part 142. When the driving part 142 rotates in a first direction (hereinafter referred to as forward rotation), it drives the output shaft 141 to rotate. At this time, the one-way motion part 144 does not output power, so the exposed length of the pulling member 190 does not change. When the driving part 142 rotates in a second direction opposite to the first direction (hereinafter referred to as reverse rotation), it drives the output shaft 141 and the one-way motion part 144 to rotate together. The rotation of the one-way motion part 144 changes the exposed length of the pulling member 190. The one-way motion part 144 is a device that moves only in a single direction. The one-way motion part 144 can adopt various types of ratchet mechanisms, which are not limited in this application.

[0098] Furthermore, in some embodiments where the drive unit 140 also includes a transmission unit 143, the one-way motion unit 144 is dynamically coupled to the transmission unit 143. Referring to FIG25, the one-way motion unit 144 includes two coupling members, one of which is fixedly connected to the transmission unit 143, and the other extends to a winding shaft 1441. One end of the pulling member 190 is fixed to the winding shaft 1441 so as to wind around the winding shaft 1441 when the winding shaft 1441 rotates.

[0099] When the drive unit 142 rotates forward and reverse, the transmission unit 143 rotates in opposite directions. The corresponding output shaft 141 can drive the vibrating element 120 to vibrate. The difference is that the vibrating direction of the vibrating element 120 is also opposite when the drive unit 142 rotates forward and reverses. When the drive unit 142 rotates in reverse, the coupling member fixedly connected to the transmission unit 143 rotates in reverse with the transmission unit 143. At this time, the anti-return surfaces of the two coupling members abut against each other. The reverse torque of the transmission unit 143 is transmitted to the winding shaft 1441 by the two coupling members, driving the winding shaft 1441 to rotate. One end of the pulling member 190 is wound around the winding shaft 1441, which shortens the length of the pulling member 190 exposed between the transmission unit 143 and the main unit 200, causing the fixed bracket 130 to move closer to the main unit 200, and the cleaning module 100 rises relative to the ground.

[0100] Referring to Figure 26, in some embodiments, the cleaning module 100 further includes a connector 180, which is hinged to the fixed bracket 130 and the main unit 200 of the cleaning device 1000, allowing the cleaning module 100 to rotate and / or rise relative to the main unit 200. To facilitate the installation of the connector 180, in some embodiments, the fixed bracket 130 is provided with an upwardly protruding mounting seat 138, and the connector 180 is hinged to the mounting seat 138. A pulling member 190 or a lifting rod extends from the main unit 200 and connects to the fixed bracket 130. By changing the length of the pulling member 190 or the lifting rod exposed outside the main unit 200, the cleaning module 100 can be moved relative to the main unit 200, and the connector 180 undergoes adaptive deformation, enabling the cleaning module 100 to rotate and / or rise relative to the main unit 200, achieving functions such as obstacle avoidance and adjustment of cleaning pressure.

[0101] Referring to Figures 26 and 27, in some embodiments, the cleaning device 1000 further includes a side brush module 500, which is located at the edge of the cleaning device 1000 and can be integrated into the cleaning module 100. As shown in Figures 26 and 27, in some embodiments, the side brush module 500 is mounted on a fixed bracket 130 and located at the corner of the fixed bracket 130. The side brush module 500 can clean the corners of the room and areas that the cleaning device 1000 cannot fully access. In some embodiments, the side brush module 500 has a built-in swing mechanism, which allows the brush head of the side brush module 500 to swing to the outside of the area covered by the cleaning device 1000, facilitating cleaning of corner areas or narrow areas. More detailed information about the side brush module 500 can be found in relevant prior art disclosures, and will not be repeated here.

[0102] Therefore, the cleaning device 1000 provided in this application has a rotary cleaning and a washing-then-mopping cleaning mode. The first cleaning section 111 of the cleaning module 100 agitates the stains on the surface to be cleaned in different directions, accelerating the separation of stains from their adhered surfaces, thus enabling faster and more efficient stain cleaning. The second cleaning section 112 of the cleaning module 100 removes water stains and residual stains left by the first cleaning section 111. The drive unit 140 of the cleaning module 100 synchronously drives the pump 160 to directly supply liquid to the first cleaning section 111 and the second cleaning section 112, improving the cleaning effect. Furthermore, the cleaning module 100 has a more compact structure, resulting in a smaller overall size of the cleaning device 1000. The flexible component 190 or the lifting rod of the cleaning device 1000 can drive the cleaning module 100 to rotate and / or rise and fall relative to the main unit 200, avoiding obstacles on the ground or preventing the wet cleaning component 110 from contacting the carpet, and adjusting the contact pressure of the first cleaning section 111 and the second cleaning section 112, further improving the cleaning effect.
