[0053] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the structure of a cleaning device 100 provided in some embodiments of this application. Figure 2 Schematic diagram of the structure of the cleaning equipment provided in some embodiments of this application Figure 2 , Figure 3 This is a schematic diagram illustrating the movement of a cleaning device 100 provided in some embodiments of this application. For ease of description, please refer to... Figure 2 In this embodiment of the application, the length direction of the cleaning device 100 is defined as the X-axis direction, the width direction of the cleaning device 100 is defined as the Y-axis direction, and the height direction of the cleaning device 100 is defined as the Z-axis direction, wherein the X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other.

[0054] It is worth noting that the qualifying terms for parallel and / or perpendicular positional relationships mentioned in this embodiment are all relative to the current technological level, and not absolute and strict definitions in a mathematical sense.

Figure 1 The orientation of the display is described as follows: the positive direction of the X-axis is "right", the negative direction of the X-axis is "left", the positive direction of the Y-axis is "front", the negative direction of the Y-axis is "back", the positive direction of the Z-axis is "top", and the negative direction of the Z-axis is "bottom".

[0055] Please see Figure 1 The cleaning equipment 100 provided in this application embodiment can be a window cleaning machine or other types of automatic cleaning equipment, and this application does not limit it.

[0056] In some embodiments, see Figure 1 The cleaning device 100 includes a housing 20, a first suction cup 30, and a second suction cup 40. The first suction cup 30 and the second suction cup 40 are used to attach the cleaning device 100 to the surface to be cleaned. The first suction cup 30 and the second suction cup 40 are vacuum suction cups. By extracting the air between the suction cup and the surface to be cleaned, the suction cup can be firmly attached to the surface to be cleaned.

[0057] In one exemplary scenario, please refer to Figure 3 The first suction cup 30 is controlled to enter the adsorption state, while the second suction cup 40 remains in the non-adsorption state. At this time, the first suction cup 30 is adsorbed onto the surface to be cleaned, and the second suction cup 40 is in a movable state. By controlling the cleaning device 100 to rotate around the axis of the first suction cup 30, the second suction cup 40 can rotate and swing around the axis of the first suction cup 30. For convenience, the second suction cup 40 after swinging is referred to as the second suction cup 40'. Then, the second suction cup 40' is switched to the adsorption state, and the adsorption state of the first suction cup 30 is released. At this time, the second suction cup 40' is fixed to the surface to be cleaned, and the first suction cup 30 is in a movable state. By controlling the cleaning device 100 to rotate around the axis of the second suction cup 40', the first suction cup 30 can rotate and swing around the axis of the second suction cup 40'. For convenience, the first suction cup 30 after swinging is referred to as the first suction cup 30'. By repeating the above process, the cleaning device 100 can move on the surface to be cleaned.

[0058] Please see Figure 1The cleaning device 100 provided in this application embodiment also includes a cleaning module 10, which is used to clean the surface to be cleaned. That is, when the cleaning device 100 moves on the surface to be cleaned, the surface to be cleaned can be cleaned by the cleaning module 10.

[0059] Please see Figures 4-6 , Figure 4 Schematic diagram of the structure of the cleaning module 10 provided in some embodiments of this application Figure 1 , Figure 5 This is a schematic diagram illustrating the movement of existing related cleaning equipment 100. Figure 6 This is a schematic diagram illustrating the movement of a cleaning device 100 provided in some embodiments of this application.

[0060] Please see Figure 4 The cleaning module 10 provided in this application embodiment includes a support 1, a cleaning unit 2 and an elastic mechanism 3. The elastic mechanism 3 connects the support 1 and the cleaning unit 2. The cleaning unit 2 is used to clean the surface to be cleaned.

[0061] The elastic mechanism 3 includes a first elastic part 31, the elastic deformation direction of the first elastic part 31 is along the first direction, so as to allow the cleaning unit 2 to abut against the surface to be cleaned. That is, the first elastic part 31 can make the cleaning unit 2 fit tightly against the surface to be cleaned, which is beneficial to improving the cleaning effect of the cleaning unit 2 on the surface to be cleaned.

[0062] See some examples. Figure 4 The first direction can be set to be parallel to the Z-axis direction of the cleaning module 10; or, in other examples, the first direction can be set to be intersecting the Z-axis direction of the cleaning module 10.

[0063] In some examples, the first elastic part 31 includes a spring, a damper, or an elastomer, etc.

[0064] In this embodiment, the elastic mechanism 3 may be slidably connected to the cleaning unit 2, and / or the elastic mechanism 3 may be slidably connected to the support 1. That is, only the elastic mechanism 3 may be slidably connected to the cleaning unit 2; or only the elastic mechanism 3 may be slidably connected to the support 1; or both the elastic mechanism 3 and the support 1 may be slidably connected.

[0065] In some examples, at least the elastic mechanism 3 is slidably connected to the cleaning unit 2 in the horizontal direction, and / or at least the elastic mechanism 3 is slidably connected to the support 1 in the horizontal direction, so that the cleaning unit 2 can move horizontally relative to the support 1.

[0066] In the embodiments of this application, please refer to Figure 4The elastic mechanism 3 also includes a second elastic part 32, the elastic deformation direction of the second elastic part 32 is along the second direction, so as to reset the cleaning unit 2 in the horizontal direction, wherein the horizontal direction refers to the direction parallel to the surface to be cleaned.

[0067] See some examples. Figure 4 The second direction can be set to be parallel to the X-axis direction of the cleaning module 10; or, in other examples, the second direction can be set to be intersecting the X-axis direction of the cleaning module 10.

[0068] In some examples, the second elastic part 32 includes a spring, a damper, or an elastomer.

[0069] In some examples, the elastic mechanism 3 includes one or more first elastic parts 31 and one or more second elastic parts 32.

[0070] Assuming that the cleaning unit 2 cannot move horizontally relative to the support 1 and the elastic mechanism 3 does not include the second elastic part 32, please refer to Figure 5 The first suction cup 30 is controlled to enter the suction state, while the second suction cup 40 is controlled to remain in the non-suction state. The second suction cup 40 is positioned close to the window frame 200. Since one end of the cleaning unit 2 is in contact with the window frame 200, the second suction cup 40 is at its closest possible position to the window frame 200, with a distance D between it and the window frame 200. The cleaning device 100 is then controlled to rotate around the axis of the first suction cup 30, allowing the second suction cup 40 to rotate and swing around the axis of the first suction cup 30. The second suction cup 40 after swinging is denoted as the second suction cup 40'. Based on the movement trajectory of the second suction cup 40... Figure 5 The area marked by the cross-section line is the area not cleaned by the cleaning unit 2. That is, when the cleaning unit 2 cannot move horizontally relative to the bracket 1 and the elastic mechanism 3 does not include the second elastic part 32, the cleaning device 100 has difficulty cleaning the area of ​​the glass near the window frame 200, thus affecting the cleaning effect of the cleaning device 100.

[0071] In this embodiment, since the cleaning unit 2 can move horizontally relative to the support 1, and the elastic mechanism 3 further includes a second elastic part 32 for resetting the cleaning unit 2 horizontally, please refer to [link to relevant documentation]. Figure 6The cleaning unit 2 controls the first suction cup 30 to enter the adsorption state while simultaneously controlling the second suction cup 40 to remain in the non-adsorption state. The second suction cup 40 is closer to the window frame 200 than the first suction cup 30. One end of the cleaning unit 2 can abut against the window frame 200 under the action of the second elastic part 32, thus allowing the second suction cup 40 to be as close to the window frame 200 as possible. The cleaning device 100 is controlled to rotate around the axis of the first suction cup 30, allowing the second suction cup 40 to rotate and swing around the axis of the first suction cup 30. During the rotation of the second suction cup 40, the cleaning unit 2 moves towards the side closer to the window frame 200 under the action of the second elastic part 32. The second suction cup 40 after swinging is denoted as the second suction cup 40'. In some exemplary scenarios, during the swinging of the second suction cup 40, the cleaning unit 2 remains in contact with the window frame 200 under the action of the second elastic part 32, ensuring that the cleaning unit 2 can effectively clean the area of ​​the glass near the window frame 200.

[0072] In this embodiment, the elastic mechanism 3 connects the bracket 1 and the cleaning unit 2. The elastic mechanism 3 includes a first elastic part 31, which allows the cleaning unit 2 to be tightly attached to the surface to be cleaned, thereby improving the cleaning effect of the cleaning unit 2 on the surface to be cleaned. The cleaning unit 2 can move horizontally relative to the bracket 1, and the elastic mechanism 3 also includes a second elastic part 32 for the cleaning unit 2 to reset horizontally, so that the cleaning unit 2 can clean the area of ​​the glass near the window frame 200, further improving the cleaning effect of the cleaning unit 2 on the surface to be cleaned.

[0073] In some embodiments, there is one or more elastic mechanisms 3. When there are two elastic mechanisms 3, each elastic mechanism 3 is connected to the bracket 1 and the cleaning unit 2 respectively.

[0074] According to the length of the cleaning unit 2, a reasonable number of elastic mechanisms 3 can be set. For example, when the length of the cleaning unit 2 is relatively small, the number of elastic mechanisms 3 can be one to simplify the structure of the cleaning module 10; when the length of the cleaning unit 2 is relatively long, the number of elastic mechanisms 3 can be two or more to help the cleaning unit 2 be stably supported on the bracket 1.

[0075] In some examples, there is one elastic mechanism 3, which includes one or more first elastic parts 31 and one or more second elastic parts 32. For example, the elastic mechanism 3 may be configured to include two or more first elastic parts 31 and one second elastic part 32, or it may be configured to include two or more second elastic parts 32 and one first elastic part 31.

[0076] In some examples, there are at least two elastic mechanisms 3, which are spaced apart along the length of the cleaning unit 2 to ensure stable support of the cleaning unit 2 on the bracket 1. In this example, each elastic mechanism 3 may include one or more first elastic parts 31 and one or more second elastic parts 32. For some examples, please refer to... Figure 4 There are two elastic mechanisms 3, each located near the corresponding end of the cleaning unit 2, to ensure stable support of the cleaning unit 2 on the bracket 1. In this example, please refer to... Figure 4 Each elastic mechanism 3 can be configured to include a first elastic part 31 and a second elastic part 32.

[0077] See some examples. Figure 4 The cleaning module 10 also includes a reinforcing rod 4, which is connected to two adjacent elastic mechanisms 3 to improve the strength of the cleaning device 100.

[0078] In some embodiments, see Figure 4 The cleaning unit 2 includes a scraper 22, which can be used to clean the surface to be cleaned. The scraper 22 is a long strip design, and it moves with the cleaning device 100 on the surface to be cleaned. A single scrape can remove stains over a large area, making the cleaning device 100 highly efficient.

[0079] In some examples, the scraper 22 is made of elastic material such as rubber or silicone, which can clean the surface to be cleaned while also protecting it.

[0080] Please see Figure 4 The cleaning unit 2 also includes a cleaning frame 21, on which a scraper 22 is supported. The cleaning frame 21 is connected to the bracket 1 via a flexible mechanism 3. In some examples, the scraper 22 is detachably connected to the cleaning frame 21 for easy replacement.

[0081] See some examples. Figure 4 The cleaning frame 21 is provided with rollers 7 at both ends along its length. The axis of the rollers 7 is along the height of the cleaning frame 21. The rollers 7 protrude from the ends of the cleaning frame 21. When the cleaning equipment 100 approaches the window frame 200, the rollers 7 come into contact with the window frame 200, reducing the resistance when the cleaning equipment 200 moves forward.

[0082] Please see Figures 7-11 , Figure 7 Schematic diagram of the structure of the cleaning module 10 provided in some embodiments of this application Figure 2 , Figure 8 for Figure 7 A magnified view of a portion of point A in the middle. Figure 9This is an exploded view of the cleaning module 10 provided in some embodiments of this application. Figure 10 for Figure 9 A magnified view of a section at point B. Figure 11 This is a schematic diagram of the structure of a cleaning frame provided in some embodiments of this application.

[0083] In some embodiments, see Figure 7 The elastic mechanism 3 also includes a connecting frame 33, which is slidably connected to the cleaning unit 2. The first elastic part 31 connects the bracket 1 and the connecting frame 33, and the second elastic part 32 connects the connecting frame 33 and the cleaning unit 2.

[0084] Please see Figure 8 The first elastic part 31 connects the bracket 1 and the connecting frame 33. In some examples, when the connecting frame 33 moves upward, the length of the first elastic part 31 extends and the first elastic part 31 provides a downward elastic tension on the connecting frame 33; or, in other examples, when the connecting frame 33 moves upward, the length of the first elastic part 31 decreases, that is, the first elastic part 31 provides a downward elastic compression on the connecting frame 33.

[0085] The connecting bracket 33 is slidably connected to the cleaning unit 2, and the cleaning unit 2 can slide along the length of the cleaning unit 2 relative to the connecting bracket 33. Please refer to [link / reference]. Figure 7 The second elastic part 32 connects the connecting frame 33 and the cleaning unit 2. When the cleaning unit 2 is in the initial position, the second elastic part 32 does not exert a force on the cleaning unit 2 along the length direction parallel to the cleaning unit 2. When the cleaning unit 2 slides from the initial position along the length direction of the cleaning unit 2, the second elastic part 32 is compressed or stretched, so that the second elastic part 32 exerts a force on the cleaning unit 2 along the length direction parallel to the cleaning unit 2. The second elastic part 32 is used to reset the cleaning unit 2 to the initial position in the horizontal direction.

[0086] See some examples. Figure 7 Two connecting frames 33 are provided on the cleaning unit 2. The two connecting frames 33 are spaced apart along the length direction of the cleaning unit 2. Each connecting frame 33 is provided with one or more first elastic parts 31 between itself and the support 1, and each connecting frame 33 is provided with one or more second elastic parts 32 between itself and the cleaning unit 2.

[0087] See some examples. Figure 7 The cleaning module 10 also includes a reinforcing rod 4, which is connected to two adjacent connecting frames 33 to improve the strength of the cleaning module 10.

[0088] In some examples, the connecting bracket 33 is plugged into the reinforcing rod 4 to facilitate the installation of the connecting bracket 33 and the reinforcing rod 4.

[0089] See some examples. Figure 8 An mounting ring 334 is formed on the connecting frame 33, and one end of the reinforcing rod 4 of the mounting ring 334 is inserted into the mounting ring 334 and the two are tightly fitted together.

[0090] In this embodiment, by setting the connecting frame 33 to slide the cleaning unit 2, the cleaning unit 2 can move horizontally relative to the support 1, while also simplifying the structural layout of the cleaning module 10.

[0091] It is worth noting that the above embodiment describes the sliding connection between the connecting frame 33 and the cleaning unit 2, the first elastic part 31 connecting the support 1 and the connecting frame 33, and the second elastic part 32 connecting the connecting frame 33 and the cleaning unit 2. In other embodiments, the elastic mechanism 3 may also include a sliding frame, which is slidably connected to the support 1, the second elastic part 32 connecting the sliding frame and the support 1, and the first elastic part 31 connecting the sliding frame and the cleaning unit 2.

[0092] The sliding frame is slidably connected to the support 1, and the sliding frame can slide relative to the support 1 along the length direction of the cleaning unit 2. The second elastic part 32 connects the sliding frame and the support 1, so that the cleaning unit 2 can move horizontally relative to the support 1. When the cleaning unit 2 is in the initial position, the second elastic part 32 does not exert a force on the sliding frame along the length direction parallel to the cleaning unit 2. When the cleaning unit 2, the first elastic part 31, and the sliding frame slide from the initial position along the length direction of the cleaning unit 2, the second elastic part 32 is compressed or stretched, so that the second elastic part 32 exerts a force on the sliding frame along the length direction parallel to the cleaning unit 2. The second elastic part 32 is used to reset the sliding frame in the horizontal direction, thereby allowing the cleaning unit 2 to reset to the initial position.

[0093] The first elastic part 31 connects the sliding frame and the cleaning unit 2. In some examples, when the cleaning unit 2 moves upward, the length of the first elastic part 31 extends, and the first elastic part 31 provides a downward elastic pulling force to the cleaning unit 2; or, in other examples, when the cleaning unit 2 moves upward, the length of the first elastic part 31 decreases, that is, the first elastic part 31 provides a downward elastic squeezing force to the cleaning unit 2.

[0094] The following description mainly uses the example of the elastic mechanism 3 including the connecting frame 33, the connecting frame 33 being slidably connected to the cleaning unit 2, the first elastic part 31 connecting the bracket 1 and the connecting frame 33, and the second elastic part 32 connecting the connecting frame 33 and the cleaning unit 2 to further describe the elastic mechanism 3.

[0095] In some embodiments, the elastic mechanism 3 further includes a guide structure for guiding the connecting frame 33 to move along a first direction.

Figure 7 When the second connecting frame 337 moves in the direction indicated by the X-axis arrow to abut against the first limiting baffle 2141, the first limiting baffle 2141 will restrict the first connecting frame 336 from continuing to move in the direction indicated by the X-axis arrow. Figure 7When the second connecting frame 337 moves in the direction indicated by the X-axis arrow to abut against the second limiting baffle 2142, the second limiting baffle 2142 will restrict the second connecting frame 337 from continuing to move away from the direction indicated by the X-axis arrow, thereby limiting the range of movement of the first connecting frame 336 and the second connecting frame 337 on the locking part 212.

[0127] In some examples, the two snap-fit ​​parts 212 have mounting slots at their opposite ends; please refer to [reference needed]. Figure 11 The diagram shows the mounting slot, in which the roller is installed.

[0128] See some examples. Figure 11 Along the width direction of the main frame 211 (i.e. Figure 11 A connecting plate 215 is provided on one side (in the Y-axis direction).

Along the direction from the slot opening 3334 to the third slot side 3333, the distance between the first slot side 3331 and the second slot side 3332 increases.

[0132] See some examples. Figure 10The first groove side 3331 is positioned above the second groove side 3332. Along the direction from the groove opening 3334 to the third groove side 3333, the first groove side 3331 is inclined upwards, and the second groove side 3332 is inclined downwards. Alternatively, in other examples, the first groove side 3331 is positioned above the second groove side 3332, and the first groove side 3331 is a plane. Along the direction from the groove opening 3334 to the third groove side 3333, the second groove side 3332 is inclined downwards. Alternatively, in other examples, the first groove side 3331 is positioned above the second groove side 3332, and along the direction from the groove opening 3334 to the third groove side 3333, the first groove side 3331 is inclined upwards, and the second groove side 3332 is a plane.

[0133] In this embodiment, the distance between the first groove side 3331 and the second groove side 3332 is set to increase along the direction from the groove opening 3334 to the third groove side 3333, so as to facilitate the connection frame 33 to be snapped onto the cleaning unit 2.

[0134] It is worth noting that the above embodiment describes the slot 333 as including a first slot side 3331, a second slot side 3332, and a third slot side 3333, with the third slot side 3333 facing the slot opening 3334 of the slot 333.

[0136] See some examples. Figure 9 The first detection component 5 is installed on the snap-fit ​​part 212 and located above the frame body 211.

[0137] In some examples, each snap-fit ​​portion 212 is provided with a first detection component 5; or, in other examples, only one snap-fit ​​portion 212 is provided with a first detection component 5.

[0138] In some examples, the first detection component 5 is a sensor or a trigger switch.

[0139] In some examples, when the cleaning unit 2 is in the initial position (i.e., the second elastic part 32 does not exert a horizontal force on the cleaning unit 2), the first detection component 5 is triggered by the connecting frame 33, and the signal triggered by the first detection component 5 is transmitted to the control device of the cleaning device 100, and the control device determines that the cleaning unit 2 is in the initial position; when the cleaning unit 2 slides relative to the connecting frame 33 so that the first detection component 5 moves away from the connecting frame 33, the first detection component 5 is not triggered by the connecting frame 33, and the control device determines that the cleaning unit 2 is not in the initial position, that is, the control device determines that the cleaning unit 2 has moved in the horizontal direction.

[0140] In this embodiment, the cleaning module 10 is further provided with a first detection component 5 for detecting the position of the elastic mechanism 3 on the cleaning unit 2, so that the cleaning device 100 can determine the operation of the cleaning module 10.

[0141] In some embodiments, see Figure 9 The cleaning module 10 also includes a second detection component 6, which is disposed on the cleaning unit 2 and is used to detect obstacles located in front of the cleaning unit 2.

[0146] In some examples, the second detection component 6 is a sensor or a trigger switch.

[0147] When the cleaning equipment 100 cleans the glass on the window, if the second detection component 6 comes into contact with the window frame 200, or if the second detection component 6 sends the detected distance signal to the control device of the cleaning equipment 100, the control device determines that the second detection component 6 is too close to the window frame 200, and then the control device can control and change the movement path of the cleaning equipment 100.

[0148] In this embodiment, the cleaning module 10 also includes a second detection component 6, so that the cleaning device 100 can determine the position of obstacles such as window frames 200 in front, so as to adjust the route in time.
