[0045] refer to Figure 1-3 , Figure 1 The present invention discloses a cleaning system 300, which includes a vacuum cleaner 100 or a base station 200 for docking with the vacuum cleaner 100, wherein the base station 200 is provided with a dust bag or dust cup for collecting dirt transferred from the vacuum cleaner 100. Figure 2 and Figure 3 Other forms of vacuum cleaners 100 were disclosed. Figure 1-3 The vacuum cleaner 100 disclosed in the paper includes a suction motor for generating suction airflow and a suction pipe for guiding the suction airflow, the suction pipe being connected to a fluid channel 13 of the cleaning assembly 102 (see reference). Figure 4 Fluid communication. Vacuum cleaner 100 can be a robotic vacuum cleaner (see reference). Figure 2 Self-cleaning equipment such as vacuum cleaners 100 and upright vacuum cleaners 100 (see reference). Figure 3 Or a handheld vacuum cleaner 100 (reference) Figure 1The vacuum cleaner 100 can be powered by its own battery pack or by connecting to a municipal power source via a power cord. When the vacuum cleaner 100 is a robotic vacuum cleaner, the cleaning component 102 can be integrated into the robotic vacuum cleaner's body 101 or detachably installed on it. When the cleaning component 102 is integrated with the robotic vacuum cleaner's body 101, the housing 1 of the cleaning component 102 is part of the robotic vacuum cleaner's body 101. When the vacuum cleaner 100 is an upright vacuum cleaner 100, the cleaning component 102 is pivotally connected to the cleaning device's body 101, and the user controls the vacuum cleaner 100 by operating the body 101. When the vacuum cleaner 100 is a handheld vacuum cleaner 100, the cleaning component 102 can be connected via a connecting rod. When the vacuum cleaner 100 is working, the cleaning device 2 is in the first cavity 110 or cleaning chamber 15 (see reference). Figure 9 The vacuum cleaner 100 (or cleaning chamber 14) operates within the chamber, and the resulting suction airflow draws the dirt from the first chamber 110 or cleaning chamber 15 into the collection box. The working principle and related structure of the vacuum cleaner 100 (excluding the cleaning component 102 disclosed in this application) are technologies familiar to those skilled in the art, and will not be described in detail here. The following focuses on describing the cleaning component 102 disclosed in this application.
[0046] refer to Figure 4-11 This section details the cleaning assembly 102 according to one embodiment. The cleaning assembly 102 includes a housing 1 and a cleaning device 2 disposed within the housing 1. The housing 1 defines a first cavity 110. The housing 1 may consist of one or more components. These components may be molded, die-cast, or manufactured using other processes, which will not be detailed here. The cleaning device 2 is used to clean the surface 400 to be cleaned. The cleaning device 2 includes a drive motor 21, a transmission structure 22, and a cleaning component 25. The cleaning component 25 is disposed within the first cavity 110. The drive motor 21 drives the cleaning component 25 to move along a motion trajectory 103 via the transmission structure 22. During operation along the motion trajectory 103, the working surface of the cleaning component 25 (the surface that can contact the surface 400 to be cleaned, such as the free end of a brush bristle or brush strip) always faces the surface 400 to be cleaned. This orientation does not necessarily mean directly facing; it can be at an angle. The cleaning assembly 102 may be provided with a flow channel that fluidly connects the first cavity 110 and the vacuum cleaner 100. Alternatively, a recycling bin can be set up directly near the first cavity 110, and the garbage can be swept directly into the recycling bin by the cleaning component 25.
[0047] refer to Figure 6-11The cleaning device 2 includes a drive motor 21, a transmission structure 22, and a cleaning component 25 (non-drum structure). The cleaning component 25 is disposed within the first cavity 110. The drive motor 21 drives the cleaning component 25 to move along a motion trajectory 103 via the transmission structure 22. The drive motor 21 can be mounted on the housing 1. The motion trajectory 103 is a closed trajectory, including a first segment and a second segment. Within the first segment (refer to...), ... Figure 11 (See Figures 2, 3, and 4 in the original text). After the cleaning component 25 leaves the surface 400 to be cleaned, within the second section (refer to Figure 1), the cleaning component 25 contacts the surface 400 to sweep the dirt onto the surface 400 towards the connecting port 16 or the collection box located on one side of the first cavity 110. The motion trajectory 103 can be a circular trajectory, an elliptical trajectory, a rectangular trajectory, or an irregular graphic trajectory. Different motion trajectories 103 can be achieved through different transmission structures 22. The wiping strip 252 (bristles or a brush strip, etc.) on the cleaning component 25 can also extend beyond the side wall 12 of the housing 1 (see Figure 2). Figure 12 This allows for the cleaning of baseboards or corners.
[0048] During the cleaning process, some hair or dust may accumulate on the upper surface of the cleaning component 25. This dirt is difficult to remove, so some improvements have been made in this area. (Reference) Figure 6-10 Specifically, a partition structure 113 is provided between the cleaning component 25 and the housing 1, which divides the first cavity 110 into a first space 114 and a second space 115 (see reference). Figure 10 Of these, some of the cleaning components 25 are located within the first space 114, while the remaining components 25 are located within the second space 115. The partition structure 113 prevents most dust or hair from entering the first space 114. The partition structure 113 can be a corrugated pipe-like structure or other forms, as long as it effectively divides the first cavity 110 into the first space 114 and the second space 115 during the movement of the cleaning components 25 along the motion trajectory 103.
[0049] In addition to its dividing function, the partition structure 113 also serves a sealing function. The partition structure 113 is generally made of a deformable material, such as soft rubber or flexible plastic. These materials are merely examples and not limitations. Other well-known materials can also be used by those skilled in the art. When a suction airflow is generated within the first cavity 110, the partition structure 113, while simultaneously sealing, can enhance the cleaning ability of the cleaning component 102 on the surface 400 to be cleaned, and prevent dust from entering the first space 114. In other embodiments, the partition structure 113 may also have ventilation holes. When the vacuum cleaner 100's suction motor is operating, airflow flows from the first space 114 to the second space 115. At this time, the flowing airflow can cool some electromechanical structures within the first space 114.
[0050] In one embodiment, the volume of the first space 114 is greater than one-quarter the volume of the first cavity 110. When the volume of the first space 114 is set relatively large, the volume of the second space 115 will be relatively small. In this case, the suction airflow will generate a relatively large suction force in the second space 115, thereby improving cleaning ability. Furthermore, the volume of the first space 114 can also be set to be greater than one-third the volume of the first cavity 110. It is even possible that the volume of the first space 114 is greater than the volume of the second space 115.
[0051] refer to Figure 6-10 In one embodiment, the housing 1 includes a first housing 111 and a second housing 112, and the partition structure 113 includes a first end 116 connected to the cleaning member 25 and a second end 117 disposed opposite to the first end 116 (see reference). Figure 6 The second end 117 of the partition structure 113 is connected to the first housing 111, or the second end 117 of the partition structure 113 is connected to the second housing 112, or the second end 117 of the partition structure 113 is fixed by both the first housing 111 and the second housing 112. Specifically, the first end 116 of the partition structure 113 can be installed to the cleaning component 25 by wrapping, gluing, or other installation methods. The second end 117 of the partition structure 113 can also be installed to the housing 1 by wrapping, gluing, or other installation methods. Figure 10 In the illustrated embodiment, the first end 116 of the partition structure 113 is fixed to the cleaning component 25 by means of adhesive coating, while the second end 117 is fixed to the housing 1 through the fit between the first housing 111 and the second housing 112. The partition structure 113 can extend or has a certain degree of elasticity to meet the movement requirements of the cleaning component 25.
[0052] Continue to refer to Figure 6-11In one embodiment, the cleaning component 25 may include a bracket 251 and a wiping strip 252 disposed on the bracket 251. The bracket 251 and the wiping strip 252 may be integrally formed or detachable. The wiping strip 252 may be a rag, scraper, or brush, etc., without detailed limitation. A partition structure 113 is provided between the bracket 251 and the housing 1. Part of the bracket 251 is located in the first space 114, and the remaining part of the bracket 251 is located in the second space 115. Specifically, the bracket 251 may include an upper surface and a lower surface disposed opposite to each other, with the upper surface of the bracket 251 located in the first space 114. The lower surface of the bracket 251 is used to install the wiping strip 252, and the lower surface is located in the second space 115. Of course, in other embodiments, the bracket 251 may also have any shape. The first end 116 of the partition structure 113 may be disposed on the bracket 251 in the manner described above, and the second end 117 of the partition structure 113 may be disposed on the housing 1 in the manner described above.
[0053] The following is in conjunction with the appendix Figure 7-10 The transmission structure 22 of the cleaning component 102 is described in detail. The housing 1 includes a first housing 111 and a second housing 112, which together define a first cavity 110. The drive motor 21 can be a common motor, which can be controlled by a controller after being powered on. The controller can be a common circuit board. The controller can control the start-up, shutdown, speed, and direction of rotation of the drive motor 21, etc. Further details are omitted here.
[0054] refer to Figure 6-10 The transmission structure 22 includes a reduction mechanism 31 and an output mechanism 32. At least part of the reduction mechanism is located within the first space 114. Placing at least part of the reduction mechanism within the first space 114 effectively reduces the space occupied by the entire cleaning assembly 102. The cleaning assembly 102 may also include a mounting bracket 271 for mounting the reduction mechanism 31 and the output mechanism 32. To further reduce the noise and vibration generated by the cleaning device 2, the mounting bracket 271 (see reference...) Figure 4 A shock-absorbing structure is provided between the mounting bracket 271 and the housing 1. The mounting bracket 271 can be a single bracket 251, or it can be composed of two separate brackets 251, one supporting the deceleration mechanism 31 and the other supporting the output mechanism 32.
[0055] refer to Figure 6-10The reduction mechanism 31 includes a primary reducer 311 and a secondary reducer 312. The input end of the primary reducer 311 is connected to the output end of the drive motor 21, and the output end of the primary reducer 311 is connected to the input end of the secondary reducer 312. The output end of the secondary reducer 312 is connected to the output mechanism 32. The primary reducer 311 can be a gear reducer, a belt reducer, or a reducer of other structures. The secondary reducer 312 can also be a gear reducer, a belt reducer, or a reducer of other structures. In the embodiment shown in the figure, the primary reducer 311 is a gear reducer, and the secondary reducer 312 is a belt reducer. The first reduction gear is mounted on the output shaft of the drive motor 21, and the second reduction gear meshes with the first reduction gear to achieve a transmission connection. The third reduction gear is coaxially arranged with the second reduction gear. The fourth reduction gear is arranged on the output mechanism 32, and the third and fourth reduction gears are connected by a belt drive. The use of at least one belt reducer in the reduction mechanism 31 can effectively block the vibration generated by the drive motor 21, thereby reducing the vibration of the output mechanism 32. The reduction mechanism also includes a mounting housing for mounting the reducer.
[0056] In the embodiment shown in the figure, the output mechanism 32 includes a first output component 321 and a second output component 322. The first output component 321 includes a first output shaft 323 and a first output member 324 and a second output member 325 located at both ends of the first output shaft 323, respectively. The second output component 322 includes a second output shaft 327 and a third output member 328 and a fourth output member 329 located at both ends of the second output shaft 327, respectively. The output end of the reduction mechanism 31 is connected to the first output shaft 323 and / or the second output shaft 327 via a drive. The first output shaft 323 and the second output shaft 327 can be synchronously connected via belts, gears, etc., to achieve synchronous rotation of the two, thereby driving the various output members to output synchronously.
[0057] Referring to the figure, to ensure the normal operation of the cleaning component 25, the transmission structure 22 also includes a first connecting rod 232 and a second connecting rod 242. The cleaning component 25 is connected to the output mechanism 32 via the first connecting rod 232 and the second connecting rod 242. The first output component 324 and the third output component 328 jointly drive the first connecting rod 232. The second output component 325 and the fourth output component 329 jointly drive the second connecting rod 242 to drive the cleaning component 25 along the motion trajectory 103 (…). Figure 11 and 16(The arrow in the diagram indicates the direction of movement). The structure of the output component is described below. The output component can be a wheel-like structure with a short shaft 244 extending from its outer surface. The short shaft 244 is offset from the rotation center of the output component, and its trajectory is a circular motion around the rotation center of the output component. The first connecting rod 232 is rotatably mounted on the short shaft 244 of the first output component 324 and the third output component 328. To improve rotational accuracy, the first connecting rod 232 and the short shaft 244 can be mounted via bearings; other common connection methods can also be used. The second connecting rod 242 is mounted on the second output component 325 and the fourth output component 329 in the same manner. Because the first output component 324, the second output component 325, the third output component 328, and the fourth output component 329 rotate synchronously, and the positions of the four short shafts 244 remain relatively consistent. When the output component rotates, it drives the first link 232 and the second link 242 to move. At this time, the movement of the first link 232 and the second link 242 drives the cleaning component 25 to move along the predetermined motion trajectory 103.
[0058] The first link 232 and the second link 242 can be T-shaped or similar to a T-shape. With this structure, when the cleaning component 25 is located within the second section (see figure), at least part of the cleaning component 25 is positioned directly below the output mechanism 32 in the vertical direction (considering only the vertical positional relationship, not the horizontal positional relationship). This arrangement effectively reduces the vibration generated by the entire cleaning device 2. To mitigate the vibration generated by the cleaning device 2, counterweights 19 are provided on the first output shaft 323 and / or the second output shaft 327 (see figure). Figure 15 ).
[0059] In other embodiments, the first link 232 and the second link 242 can also be long strip structures with curved front ends. With this structure, the motion trajectory 103 in the horizontal direction (considering only the positional relationship in the horizontal direction and not the positional relationship in the vertical direction) is located in front of the output mechanism 32, which can reduce the overall height of the cleaning assembly 102.
[0060] refer to Figure 10 When the drive motor 21 along the height direction of the cleaning component 102 is positioned above the output mechanism, in order to make the overall height of the cleaning component 102 lower, the lowest point of the drive motor 21 along the height direction of the cleaning component 102 is lower than the highest point of the first output component 321 or the second output component 322. This configuration can effectively reduce the height of the entire device, especially when installed on a robotic vacuum cleaner, making it easier for the robotic vacuum cleaner to clean low areas.
[0061] To achieve balance in the entire cleaning assembly 102 and effectively reduce vibration, the drive motor 21 is positioned at the center of the housing 1 along the length of the cleaning assembly 102. This center position is not necessarily the exact center of the feature; it can be slightly offset. Furthermore, to reduce vibration generated by the cleaning component 25 during movement, counterweights 19 can be provided on the first output shaft 323 and / or the second output shaft 327. Providing counterweights 19 on the output shafts effectively reduces overall vibration. (Continue to refer to...) Figure 9 and 10 Similarly, to further reduce vibration, when the cleaning component 25 comes into contact with the surface 400 to be cleaned, at least part of the cleaning component 25 is located directly below the output mechanism 32 in the vertical direction.
[0062] refer to Figure 12-16 As shown in the embodiment illustrated, a cleaning assembly 102 is disclosed. The cleaning assembly 102 includes a housing 1 for moving on a surface 400 to be cleaned. Multiple rollers may be mounted on the housing 1. The housing 1 may be assembled from multiple injection-molded parts. (Reference) Figure 14 The housing 1 defines a fluid channel 13 for guiding the flow of suction airflow. The housing 1 also defines a first cavity, which is in fluid communication with the fluid channel 13. The first cavity can be a single cavity. The first cavity may also include a suction cavity 14 and a cleaning cavity 15 in fluid communication. The cleaning cavity 15 and the fluid channel 13 are located on opposite sides of the suction cavity 14. Along the forward direction of the cleaning device, the cleaning cavity 15 can be located either in front of or behind the suction cavity 14, as long as the suction cavity 14 is located between the cleaning cavity 15 and the fluid channel 13. The suction cavity 14 is responsible for the fluid communication between the fluid channel 13 and the cleaning cavity 15.
[0063] The housing 1 defines a suction chamber 14 in fluid communication with the fluid channel 13 and a cleaning chamber 15 disposed in front of the suction chamber 14. The suction chamber 14 and the cleaning chamber 15 are in fluid communication through at least one connecting port 16. The connecting port 16 can be trapezoidal, and its cross-section gradually decreases along the airflow direction. This arrangement can effectively improve cleaning ability.
[0064] As shown in the embodiment, the height of the suction chamber 14 is less than the height of the cleaning chamber 15 in the vertical direction. Limiting the suction chamber 14 to a smaller size can effectively reduce suction loss and improve cleaning ability.
[0065] The cleaning assembly 102 includes a housing 1 and a cleaning device 2 disposed in the housing 1. The cleaning device 2 includes a drive motor 21, a transmission structure 22, and a cleaning component 25 (non-drum structure). The cleaning component 25 is disposed within the first cavity 110. The drive motor 21 drives the cleaning component 25 to move along a motion trajectory 103 through the transmission structure 22. The motion trajectory 103 is a closed trajectory and includes a first segment and a second segment. Within the first segment (see reference...) Figure 16 (See the first four images in the image). Cleaning component 25 is 400 mm away from the surface to be cleaned, within the second section (see reference). Figure 16 (See the third figure). The cleaning component 25 contacts the surface 400 to be cleaned, sweeping dirt from the surface 400 towards the connecting port 16 or the collection box located on one side of the first cavity 110. The motion trajectory 103 can be a circular trajectory, an elliptical trajectory, a rectangular trajectory, or an irregular graphic trajectory. Different motion trajectories 103 can be achieved through different transmission structures 22. The wiping strips 252 (bristles or brush strips, etc.) on the cleaning component 25 can also extend out of the side wall 12 of the housing 1 to clean the baseboard or corners. The cleaning component 102 in another embodiment is described below with reference to the accompanying drawings.
[0066] The housing 1 includes an upper outer shell 17 and a lower outer shell 18, with an installation space 28 defined between them. The drive motor 21 can be a common motor, which can be controlled by a controller after being powered on. The controller can be a common circuit board. The controller can control the start-up, shutdown, speed, and rotation direction of the drive motor 21, etc., which will not be described in detail here. A partition structure 113 is provided between the cleaning component 25 and the housing 1 (refer to the partition structure 113 in the above embodiment, and also refer to...). Figure 14 The partition structure 113 divides the first cavity (or cleaning cavity 15) into a first space 114 and a second space 115. Part of the cleaning component 25 is located in the first space 114, and the remaining part is located in the second space 115. The partition structure 113 can prevent most dust or hair from entering the first space 114. The partition structure 113 can be a corrugated pipe-like structure, or other forms of structure, as long as it can effectively divide the first cavity or cleaning cavity into the first space 114 and the second space 115 during the movement of the cleaning component 25 along the motion trajectory 103.
[0067] In addition to its dividing function, the partition structure 113 also serves a sealing function. The partition structure 113 is generally made of a deformable material, such as soft rubber or flexible plastic. These materials are merely examples and not limitations. Those skilled in the art can also use other known materials. When a suction airflow is generated within the first cavity 110, the partition structure 113 simultaneously acts as a seal, enhancing the cleaning ability of the cleaning component 102 on the surface 400 to be cleaned, while preventing dust from entering the first space 114. In other embodiments, the partition structure 113 may also have ventilation holes. When the vacuum cleaner 100's suction motor is operating, airflow flows from the first space 114 to the second space 115. This flowing airflow can cool some electromechanical structures within the first space 114.
[0068] In one embodiment, the volume of the first space 114 is greater than one-quarter of the volume of the first cavity 110. When the volume of the first space 114 is set to be relatively large, the volume of the second space 115 will be relatively small. In this case, the airflow will generate a greater suction force in the second space 115, thereby improving cleaning ability. Furthermore, the volume of the first space 114 can also be set to be greater than one-third of the volume of the first cavity 110. It can even be set so that the volume of the first space 114 is greater than the volume of the second space 115.
[0069] refer to Figure 12-16 The transmission structure 22 includes a reduction mechanism 31 and an output mechanism 32. A mounting bracket 271 is used to mount the reduction mechanism 31 and the output mechanism 32. To further reduce the noise and vibration generated by the cleaning device 2, a shock-absorbing structure is provided between the mounting bracket 271 and the housing 1. The mounting bracket 271 can be a single bracket 251, or it can consist of two separate brackets 251, one supporting the reduction mechanism 31 and the other supporting the output mechanism 32.
[0070] refer to Figure 12-16 The reduction mechanism 31 includes a primary reducer 311 and a secondary reducer 312. The input end of the primary reducer 311 is drive-connected to the output shaft of the drive motor 21. The output end of the primary reducer 311 is drive-connected to the input end of the secondary reducer 312. The output end of the secondary reducer 312 is drive-connected to the output mechanism 32. (Reference) Figure 7The output mechanism 32 includes a first output component 321 and a second output component 322. The first output component 321 includes a first output shaft 323 and a first output member 324 and a second output member 325 located at both ends of the first output shaft 323, respectively. The second output component 322 includes a second output shaft 327 and a third output member 328 and a fourth output member 329 located at both ends of the second output shaft 327, respectively. The output end of the two-stage reducer 312 is driveably connected to the first output shaft 323 and / or the second output shaft 327. The transmission structure 22 also includes a first connecting rod 232 and a second connecting rod 242, through which the cleaning member 25 is driveably connected to the output mechanism 32. The first output member 324 and the third output member 328 jointly drive the first connecting rod 232; the second output member 325 and the fourth output member 329 jointly drive the second connecting rod 242, so as to drive the cleaning member 25 to move along the motion trajectory 103. A reduction gear mechanism 31, especially a belt reduction gear mechanism 31, is provided upstream of the output mechanism 32. This can effectively reduce the transmission of vibration between the drive motor 21 and the output mechanism 32, thereby reducing noise and the vibration amplitude of the entire cleaning assembly 102. At the same time, by not implementing additional speed reduction within the output mechanism 32, the stability of the output mechanism 32 can be maximized.
[0071] Specifically, refer to Figure 15The first-stage reducer 311 includes a belt and gears located at both ends of the belt. This reduction mechanism initially reduces the speed output by the drive motor 21. The second-stage reducer 312 includes a belt and gears located at both ends of the belt to achieve further speed reduction. The output gear of the second-stage reducer 312 is fixedly connected to the first output shaft 323 to drive the first output shaft 323 to rotate. The first output shaft 323 drives the first output component 324 and the second output component 325 at both ends. The first output component 324 and the second output component 325 are gear structures. At the same time, the third output component 328 and the fourth output component 329 are also gear structures. The first output component 324 meshes with the third output component 328, and the second output component 325 meshes with the fourth output component 329. The structure of the output component is described below. The output component can be a wheel-shaped structure with a short shaft 244 extending from its outer surface. The short shaft 244 is offset from the rotation center of the output component, and its motion trajectory 103 is a circular motion around the rotation center of the output component. The first connecting rod 232 is rotatably mounted on the short shaft 244 of the first output component 324 and the third output component 328. To improve rotational accuracy, the first connecting rod 232 and the short shaft 244 can be connected via bearings; other common connection methods can also be used. The second connecting rod 242 is mounted on the second output component 325 and the fourth output component 329 in the same manner. Since the first output component 324, the second output component 325, the third output component 328, and the fourth output component 329 rotate synchronously, and the positions of the four short shafts 244 remain relatively consistent, when the output component rotates, it drives the first connecting rod 232 and the second connecting rod 242 to move. At this time, the movement of the first connecting rod 232 and the second connecting rod 242 drives the cleaning component 25 to move along the predetermined motion trajectory 103.
[0072] In other embodiments, the output of the two-stage reducer 312 can simultaneously drive the first output shaft 323 and the second output shaft 327 via one output shaft. Gears are mounted on the output shafts, and corresponding gear structures are mounted on the first output shaft 323 and the second output shaft 327, respectively, to achieve synchronous transmission through the combination of different gears.
[0073] refer to Figure 15 The first link 232 and the second link 242 can be T-shaped or similar to a T-shape. The first link 232 with this structure, when the cleaning component 25 is located within the second section (see reference...). Figure 16 In the vertical direction (considering only the vertical positional relationship, not the horizontal positional relationship), at least part of the cleaning component 25 is located directly below the output mechanism 32. This arrangement effectively reduces the vibration generated by the entire cleaning device 2. To mitigate the vibration generated by the cleaning device 2, counterweights 19 are provided on the first output shaft 323 and / or the second output shaft 327 (see reference). Figure 15 ).
[0074] In other embodiments, the first link 232 and the second link 242 can also be long strip structures with curved front ends. With this structure, the motion trajectory 103 in the horizontal direction (considering only the positional relationship in the horizontal direction and not the positional relationship in the vertical direction) is located in front of the output mechanism 32, which can reduce the overall height of the cleaning assembly 102.
