[0020] In one implementation, a clearance through hole is formed between the upper support housing and the lower support housing. Two racks are provided on the outer surface of the upper support housing. The lifting structure includes a drive shaft that passes through the clearance through hole and is rotatably connected to the support frame at both ends. Two drive gears are provided on the drive shaft, and each drive gear meshes with a corresponding rack.

[0021] In one implementation, both the second cleaning component and the first cleaning component include cleaning elements for contacting and cleaning the ground, wherein the material hardness of the cleaning element of the second cleaning component is greater than that of the cleaning element of the first cleaning component.

[0022] In one implementation, the cleaning seat includes two roller assemblies, both of which are rotatably connected to the support frame. The two roller assemblies are spaced apart relative to each other along a first direction. A first cleaning component is spaced apart from the two roller assemblies along a second direction. The first and second directions are perpendicular to each other. The second cleaning component is disposed between one of the roller assemblies and the first cleaning component.

[0026] The beneficial effects of this application are as follows: The cleaning seat provided in this embodiment includes a first cleaning component and a second cleaning component, and the second cleaning component is height-adjustable via a lifting structure. When it is necessary to clean stubborn stains on the floor, the lifting structure moves the second cleaning component downward to a position in contact with the ground to clean the stubborn stains on the floor; when the second cleaning component is not needed, the lifting structure moves the second cleaning component upward to a position separated from the ground, and the first cleaning component cleans the floor. That is, the cleaning seat provided in this embodiment, since the second cleaning component only contacts the floor when needed, allows the cleaning seat to clean stubborn stains without affecting the floor or the operation of the cleaning seat.

[0055] Figure 1 This is a schematic diagram of the structure of the cleaning seat 100 provided in the embodiments of this application. Figure 2 This is a bottom view of the cleaning seat 100 provided in an embodiment of this application. Figure 3 This is a schematic diagram of the internal structure of the cleaning seat 100 provided in an embodiment of this application. Before describing the cleaning seat 100 provided in this embodiment, the following directional definitions are made: the cleaning seat 100 can be calibrated by the following three mutually perpendicular axes: the X-axis, the Y-axis, and the Z-axis. For details, please refer to... Figures 1-2 The Z-axis is along the height direction of the cleaning seat 100, the Y-axis is the movement direction of the cleaning seat 100 during cleaning, and the X-axis is the axial direction of the cleaning roller on the cleaning seat 100.

[0056] The cleaning seat 100 provided in this embodiment includes a support frame 1, a first cleaning unit, and a second cleaning unit.

[0057] Please see Figure 1 The image illustrates the appearance of the cleaning seat 100, which can be used in handheld cleaning devices, such as handheld floor scrubbers. The cleaning seat 100 is used to clean the surface to be cleaned as it moves across the floor.

[0058] Please see Figure 2 ,for Figure 1 A bottom view of the cleaning seat 100, i.e., along Figure 1 The view formed by projecting the direction indicated by the arrow on the Z-axis. Figure 2 The diagram illustrates the side of the cleaning seat 100 that contacts the ground. The first cleaning unit includes a first cleaning component 2 rotatably connected to the support frame 1, as shown in Figure 2. The first cleaning component 2 is supported on the support frame 1, and the two ends of the first cleaning component 2 along its length direction are... Figure 2 The two ends in the X-axis direction are rotatably connected to the support frame 1. When the first cleaning component 2 rotates, it can clean the surface to be cleaned, such as the ground.

[0059] In one example, the first cleaning unit further includes a main cleaning roller drive device connected to the first cleaning component 2. The main cleaning roller drive device is supported on the support frame 1 and is used to drive the first cleaning component 2 to rotate so that when the cleaning seat 100 moves on the surface to be cleaned, the main cleaning roller drive device drives the first cleaning component 2 to rotate to clean the surface to be cleaned.

[0060] The first cleaning component 2 can only rotate relative to the support frame 1 along its own axis. The first cleaning component 2 cannot be adjusted in height relative to the support frame 1. Figure 1 The first cleaning component 2 cannot be adjusted in the Z-axis direction. When the cleaning seat 100 is... Figure 1 When supported on the ground, the first cleaning component 2 is always in contact with the ground.

[0061] Specifically, the first cleaning component 2 typically includes a support roller and a cleaning component mounted on the support roller. The cleaning component is used to contact the ground and clean it. The support roller rotates and is supported on the support frame 1. The cleaning component of the first cleaning component 2 can be a roller brush, a cloth, or a cleaning tray, etc. Since the first cleaning component 2 is always in contact with the floor, if the material of the cleaning component on the first cleaning component 2 is a hard material, it may scratch the floor due to prolonged contact. Therefore, to protect the floor from scratches, the material of the cleaning component on the first cleaning component 2 is a soft material. Here, "soft material" refers to a material that is difficult for the cleaning seat 100 to scratch the floor during long-term use. Specifically, the material of the cleaning component on the first cleaning component 2 can be brush bristles, a cloth, or silicone, etc. For example, when the material of the cleaning component on the first cleaning component 2 is brush bristles, the bristles are soft, making it less likely to scratch the surface to be cleaned.

[0062] To protect the floor, the cleaning components on the first cleaning unit 2 are made of a soft material. However, stubborn stains occasionally appear on the floor in the home. When cleaning stubborn stains with the first cleaning unit 2, the cleaning effect is often poor and the cleaning efficiency is low. In most cases, users need to manually clean the stubborn stains.

[0063] Based on this, the cleaning seat 100 provided in this embodiment also includes a second cleaning unit, which can be used to clean stubborn stains on the floor. Specifically, the second cleaning unit includes a second cleaning component 3 and a lifting structure 4. The second cleaning component 3 is connected to the lifting structure 4, which is supported on the support frame 1. The lifting structure 4 is used to move the second cleaning component 3 up and down to change the state of contact between the second cleaning component 3 and the ground. Please refer to [link / reference]. Figure 2 This illustrates the second cleaning component 3.

[0064] Please see Figure 1 The diagram illustrates the upper housing 11 and lower housing 12 of the support frame 1. The upper housing 11 is positioned above the lower housing 12 and the two are connected. Please refer to [link / reference]. Figure 3 , Figure 3 The upper housing 11 is not shown, but the interior of the cleaning seat 100 is shown. (See diagram below.) Figure 3 As shown, the lifting structure 4 supported on the lower housing 12 is illustrated.

[0065] In this embodiment, for stubborn stains that are difficult to clean by the first cleaning component 2, the second cleaning component 3 can be used for cleaning. Specifically, when it is necessary to clean stubborn stains on the floor, the lifting structure 4 is controlled to move downwards to a position in contact with the ground, and the stubborn stains on the floor are cleaned by the second cleaning component 3; when there are no stubborn stains on the ground (or when the second cleaning component 3 is not needed), the lifting structure 4 is controlled to move upwards to a position separated from the ground. At this time, when the cleaning seat 100 moves on the floor, only the first cleaning component 2 cleans the floor, while the second cleaning component 3 does not contact the floor. Please refer to [link to relevant documentation]. Figure 4 and Figure 5 , Figure 4 and Figure 5 This is a cross-sectional view of the cleaning seat 100. Figure 4 and Figure 5 The ground is represented by a horizontal dashed line. Figure 4 This illustrates the gap between the second cleaning component 3 and the ground along the Z-axis. Figure 5 This illustrates the state of the second cleaning component 3 when it is in contact with the ground.

[0066] In this embodiment, the lifting structure 4 can be controlled manually to change the position of the second cleaning component 3 along the height direction, or the lifting structure 4 can be controlled automatically. Preferably, the lifting structure 4 is controlled automatically to change the position of the second cleaning component 3 along the height direction, so as to facilitate user operation.

[0067] The cleaning seat 100 provided in this embodiment includes a first cleaning component 2 and a second cleaning component 3. The second cleaning component 3 is height-adjustable via a lifting structure 4. When it is necessary to clean stubborn stains on the floor, the lifting structure 4 moves the second cleaning component 3 downward to a position in contact with the ground to clean the stubborn stains. When the second cleaning component 3 is not needed, the lifting structure 4 moves the second cleaning component 3 upward to a position separated from the ground, and the first cleaning component 2 cleans the floor. That is, the cleaning seat 100 provided in this embodiment, since the second cleaning component 3 only contacts the floor when needed, ensures that the cleaning seat 100 can clean stubborn stains without affecting the floor or the operation of the cleaning seat 100.

[0068] In one embodiment, the second cleaning component 3 has a stronger cleaning ability than the first cleaning component 2, so as to facilitate the use of the second cleaning component 3 to clean stubborn stains.

[0069] In one implementation scenario, for example, the cleaning element on the second cleaning component 3, used to contact and clean the floor, is made of a hard material to clean stubborn stains on the floor. Regarding the hard material, it can be understood that the hardness of the cleaning element on the second cleaning component 3 is greater than the hardness of the cleaning element on the first cleaning component 2. Because the cleaning element on the second cleaning component 3 is made of a hard material, to prevent damage to the floor from prolonged contact, a lifting structure 4 connects the second cleaning component 3 and the support frame 1. When the second cleaning component 3 is not needed, it can be moved upwards to a position separated from the floor via the lifting structure 4.

[0070] In another implementation scenario, for example, when the material of the cleaning element on the second cleaning component 3 is a rag, the lifting structure 4 can move the second cleaning component 3 downwards until it is pressed against the ground. This increases the friction between the second cleaning component 3 and the floor during movement, thereby improving the cleaning ability of the second cleaning component 3 and enabling the cleaning of stubborn stains on the floor. Because the second cleaning component 3 is pressed against the ground, the high friction is not conducive to the movement of the cleaning seat 100 along the floor. Therefore, the lifting structure 4 is used to connect the second cleaning component 3 and the support frame 1. When the second cleaning component 3 is not needed, the lifting structure 4 can move the second cleaning component 3 upwards to a position separated from the ground.

[0071] The cleaning seat 100 provided in this embodiment is configured such that the second cleaning component 3 has a stronger cleaning ability than the first cleaning component 2, so that the second cleaning component 3 can be used to clean stubborn stains on the ground.

[0072] Regarding the second cleaning unit, in one embodiment, the second cleaning unit further includes a drive structure 5, which is connected to the second cleaning component 3, and a lifting structure 4 is connected to the drive structure 5. The drive structure 5 is used to drive the second cleaning component 3 to rotate in order to clean the ground.

[0073] Please see Figure 3 The diagram illustrates the drive structure 5. In this embodiment, the second cleaning component 3 is connected to the lifting structure 4 via the drive structure 5. When the drive structure 5 is activated, it can drive the second cleaning component 3 to rotate, that is, the drive structure 5 can drive the second cleaning component 3 to rotate along its own axis. The lifting structure 4 is connected to the drive structure 5. When the lifting structure 4 is activated, it can drive the drive structure 5 and the second cleaning component 3 to move together in the height direction.

[0074] In this embodiment, the second cleaning component 3 can be a roller brush. Specifically, the second cleaning component 3 includes a rotating roller and bristles (the bristles are the cleaning parts of the second cleaning component 3). The bristles are distributed on the rotating roller, and the rotating roller is connected to the drive structure 5. Alternatively, in this embodiment, the second cleaning component 3 includes a rotating roller and a cloth (the cloth is the cleaning part of the second cleaning component 3). The cloth is wrapped around the rotating roller, and the rotating roller is connected to the drive structure 5.

[0075] In this embodiment, the second cleaning component 3 is rotated by the drive structure 5 to clean the ground, which makes it easier for the cleaning seat 100 to clean stubborn stains on the ground.

[0076] Regarding the second cleaning unit, in one embodiment, the second cleaning unit further includes a translation drive structure connected to the second cleaning component 3, and a lifting structure 4 connected to the translation drive structure. The translation drive structure is used to drive the second cleaning component 3 to move in order to clean the ground.

[0077] When the translation drive structure moves, it can drive the second cleaning component 3 to move back and forth, that is, the translation drive structure can drive the cleaning component 3 along... Figure 1 The horizontal reciprocating or translational drive structure along the X-axis can drive the cleaning component 3 along... Figure 1 The device moves horizontally back and forth along the Y-axis to clean the ground. The lifting structure 4 is connected to the translation drive structure. When the lifting structure 4 moves, it can drive the translation drive structure and the second cleaning component 3 to move together along the height direction.

[0078] In this embodiment, the second cleaning component 3 can be a scraper. The second cleaning component 3 is driven to move back and forth by a translational drive structure so as to scrape and wash the floor.

[0079] Regarding the translation drive structure, the translation drive structure can be a cylinder; or, the translation drive structure can be other linear mechanisms that can drive the second cleaning component 3 to move back and forth.

[0080] In this embodiment, the second cleaning component 3 is driven to move back and forth by the translation drive structure to clean the ground, which makes it easier for the cleaning seat 100 to clean stubborn stains on the ground.

[0081] Regarding the second cleaning unit, in one embodiment, the second cleaning component 3 is directly connected to the lifting structure 4, meaning the second cleaning unit does not include the drive structure 5. In this case, the second cleaning component 3 can be a scraper. When the second cleaning component 3 moves downward to the position in contact with the ground under the drive of the lifting structure 4, the user can push the cleaning seat 100 along... Figure 1 The device moves back and forth along the Y-axis to enable the second cleaning component 3 to scrape and clean the floor.

[0082] In this embodiment, the second cleaning component 3 is directly connected to the lifting structure 4, which simplifies the structure of the second cleaning unit and saves costs.

[0083] Please see Figures 6-9 , Figure 6 A cross-sectional schematic diagram of the second cleaning unit provided in an embodiment of this application; Figure 7 This is a schematic diagram of the structure of the drive structure 5 supported on the support housing 6 according to an embodiment of this application; Figure 8 Another schematic diagram of the drive structure 5 provided in this application embodiment being supported on the support housing 6;

[0084] Figure 9 This is a schematic diagram of the structure of the lifting structure 4 provided in the embodiment of this application, in which the transmission gear 43 and rack 44 cooperate.

[0085] To improve structural stability, in an example where the drive structure 5 is used to drive the second cleaning component 3 to rotate for cleaning the ground, in one embodiment, the second cleaning unit includes a support housing 6, the support housing 6 has a cavity 621 formed inside to accommodate the second cleaning component 3, the bottom of the support housing 6 has a bottom opening 622 that communicates with the cavity 621, the second cleaning component 3 is supported on the support housing 6 and rotatably connected to the support housing 6, and the second cleaning component 3 protrudes from the bottom opening 622.

[0086] Please see Figure 7 This illustrates the supporting shell 6. Figure 7The diagram illustrates the drive structure 5 supported on the support housing 6. Please refer to [link / reference]. Figure 6 The diagram illustrates the cavity 621 and the bottom opening 622. Figure 6 The diagram illustrates the second cleaning component 3 located within cavity 621. Please refer to [link / reference]. Figure 6 The diagram shows that the second cleaning component 3 is a roller brush. The rotating roller of the second cleaning component 3 is supported on the support housing 6, and the bristles of the second cleaning component 3 can extend out of the cavity 621 from the bottom opening 622.

[0087] In this embodiment, the second cleaning component 3 is supported on the support housing 6 and rotatably connected to the support housing 6. Preferably, both ends of the second cleaning component 3 are supported on the support housing 6 by bearings.

[0088] The second cleaning unit provided in this embodiment includes a support housing 6, which can improve the stability of the second cleaning unit structure.

[0089] In one embodiment, the drive structure 5 is supported on the support housing 6 and is connected to the second cleaning component 3 in a transmission manner, and the lifting structure 4 is connected to the support housing 6.

[0090] In this embodiment, both the drive structure 5 and the second cleaning component 3 are mounted on the support housing 6. When the lifting structure 4 is activated, it drives the support housing 6 to move along the height direction, thereby adjusting the position of the drive structure 5 and the second cleaning component 3 along the height direction.

[0091] Regarding the driving structure 5, in one embodiment, please refer to... Figure 7 The drive structure 5 includes a drive motor 51 and a first reducer 52. The shaft of the drive motor 51 is connected to the second cleaning component 3 through the first reducer 52.

[0092] Regarding the first reducer 52, it is preferably a reduction gear set structure. The reduction gear set uses a transmission method where a small gear drives a large gear. Since the large gear has more teeth than the small gear, according to the transmission ratio, the speed of the large gear will decrease. When the speed decreases, the torque will increase. By reducing the speed, the reduction gear set increases the torque of the output shaft, enabling it to drive a larger load, which facilitates the second cleaning component 3 in cleaning the ground.

[0093] The drive structure 5 provided in this embodiment is simple in structure and provides stable and accurate transmission.

[0094] In one embodiment, the drive motor 51 is located at one end of the support housing 6 away from the bottom opening 622, and the first reducer 52 is located on the same side as the drive motor 51 and the support housing 6.

[0095] Please see Figure 7The diagram illustrates that the drive motor 51 is supported on top of the support housing 6. When the drive motor 51 is activated, it can drive the second cleaning component 3 to rotate via the first reducer 52, thereby enabling the second cleaning component 3 to clean the ground.

[0096] The layout of the drive motor 51 and the first reducer 52 provided in this embodiment allows for a compact layout of the cleaning seat.

[0097] Regarding the lifting structure 4, in one embodiment, the lifting structure 4 includes a lifting motor 41, a transmission gear 43, and a rack 44. The lifting motor 41 is supported on the support frame 1, the rack 44 is fixed on the support housing 6, the transmission gear 43 meshes with the rack 44, the lifting motor 41 is connected to the transmission gear 43, and the transmission gear 43 is rotatably supported on the support frame 1. Alternatively, in one embodiment, the lifting structure 4 includes a lifting motor 41, a second reducer 42, a transmission gear 43, and a rack 44. The lifting motor 41 is supported on the support frame 1, the rack 44 is fixed on the support housing 6, the lifting motor 41 is connected to the transmission gear 43 via the second reducer 42, the transmission gear 43 meshes with the rack 44, and the transmission gear 43 is rotatably supported on the support frame 1.

[0098] Please see Figure 6 The diagram illustrates the lifting motor 41, the second reducer 42, the transmission gear 43, and the rack 44. Figure 6 The diagram shows that the rack 44 is formed on the support housing 6.

[0099] The lifting motor 41 is fixed on the support frame 1 of the cleaning seat 100. When the lifting motor 41 is activated, for example, when the lifting motor 41 rotates in the forward direction, it can drive the transmission gear 43 to rotate through the second reducer 42. Since the transmission gear 43 meshes with the rack 44, when the transmission gear 43 rotates, it can drive the rack 44 to move downward, thereby causing the support frame 1, the drive structure 5 and the second cleaning component 3 to move downward together. When the lifting motor 41 rotates in the reverse direction, it can drive the rack 44 to move upward, thereby causing the support frame 1, the drive structure 5 and the second cleaning component 3 to move upward together.

[0100] Regarding the second reducer 42, a reduction gear set structure is preferred. This reduction gear set uses a small gear to drive a large gear. Since the large gear has more teeth than the small gear, its rotational speed decreases according to the transmission ratio. As the rotational speed decreases, the torque increases. By reducing the rotational speed, the reduction gear set increases the torque on the output shaft, enabling it to drive a larger load.

[0101] The lifting structure 4 provided in this embodiment includes a lifting motor 41, a second reducer 42, a transmission gear 43, and a rack 44. It has a simple structure and stable and accurate transmission.

[0102] Regarding the stopping positions of the second cleaning component 3 when it moves upward and downward, in one embodiment, the cleaning seat 100 is provided with a first position detection sensor and a second position detection sensor. Both the first and second position detection sensors are connected to a controller. When the support housing 6 moves downward to the target low position, the first position detection sensor detects the position information of the support housing 6 and transmits the detected position information to the controller. After receiving the signal, the controller controls the lifting motor 41 to stop. When the support housing 6 moves upward to the target high position, the second position detection sensor detects the position information of the support housing 6 and transmits the detected position information to the controller. After receiving the signal, the controller controls the lifting motor 41 to stop.

[0103] Regarding the stopping positions of the second cleaning component 3 when it moves upward and downward, in another embodiment, the stopping positions of the second cleaning component 3 when it moves upward and downward are controlled by controlling the running time of the lifting motor 41. Specifically, when the lifting structure 4 drives the supporting housing 6 to move downward and the operating time of the lifting motor 41 reaches a preset value, the controller controls the lifting motor 41 to stop operating. At this time, the supporting housing 6 is located at the target low position, and the second cleaning component 3 is in contact with the ground. When the lifting structure 4 drives the supporting housing 6 to move upward and the operating time of the lifting motor 41 reaches a preset value, the controller controls the lifting motor 41 to stop operating. At this time, the supporting housing 6 is located at the target high position, and the second cleaning component 3 is separated from the ground.

[0104] In one embodiment, please refer to Figure 7 The support housing 6 includes an upper support housing 61 and a lower support housing 62. The upper support housing 61 is connected to the lower support housing 62. The lower support housing 62 has a cavity 621 and a bottom opening 622. The upper support housing 61 is located on the side of the lower support housing 62 away from the bottom opening 622. The drive structure 5 is supported on the upper support housing 61.

[0105] In this embodiment, the support housing 6 includes an upper support housing 61 and a lower support housing 62. The support housing 6 has few parts, which facilitates its assembly.

[0106] Please see Figure 7 In one embodiment, a clearance through hole 63 is formed between the upper support housing 61 and the lower support housing 62, and two toothed racks 44 are provided on the outer surface of the upper support housing 61. Please refer to [link to relevant documentation]. Figure 6 The lifting structure 4 includes a drive shaft 45, which passes through the clearance through hole 63 and is rotatably connected to the support frame 1 at both ends. Two drive gears 43 are provided on the drive shaft 45, and each drive gear 43 meshes with a corresponding rack 44.

[0107] Regarding the clearance through hole 63, the shapes of the upper support housing 61 and the lower support housing 62 can be designed so that when the upper support housing 61 and the lower support housing 62 are assembled together, a clearance through hole 63 is formed between the upper support housing 61 and the lower support housing 62.

[0108] Please see Figure 7 The diagram illustrates the rack 44, which is preferably integrally formed with the upper support housing 61. Please refer to [link / reference]. Figure 6 This illustrates that two transmission gears 43 mesh with their corresponding racks 44.

[0109] In this embodiment, both ends of the drive shaft 45 are rotatably connected to the support frame 1, and both ends of the drive shaft 45 can be supported on the support frame 1 by bearings respectively.

[0110] The structure of the support housing 6 provided in this embodiment can make the structure of the second cleaning unit compact while reasonably arranging the lifting structure 4. In addition, by setting two transmission gears 43 to mesh with the corresponding racks 44, the transmission can be stable, which is conducive to the stable rise and fall of the support frame 1, the drive structure 5 and the second cleaning component 3.

[0111] In an example where a translational drive structure is used to move the second cleaning component 3 to clean the ground, in one embodiment, the second cleaning unit includes a support housing 6, with a cavity 621 formed inside the support housing 6 to accommodate the second cleaning component 3. The bottom of the support housing 6 has a bottom opening 622 communicating with the cavity 621. The second cleaning component 3 is supported on the support housing 6, and the support housing 6 can guide the movement of the second cleaning component 3. The second cleaning component 3 protrudes from the bottom opening 622. A drive structure 5 is supported on the support housing 6 and is connected to the second cleaning component 3 in a transmission manner. A lifting structure 4 is connected to the support housing 6.

[0112] In this embodiment, the support housing 6 can guide the second cleaning component 3 to move. For example, a slide rail structure can be formed between the support housing 6 and the second cleaning component 3. When the translation drive structure is activated, the translation drive structure can drive the cleaning component 3 along... Figure 1 The horizontal reciprocating or translational drive structure along the X-axis can drive the cleaning component 3 along... Figure 1 It moves horizontally back and forth along the Y-axis to clean the ground.

[0113] In an example based on the second cleaning unit including the support housing 6, in one embodiment, please refer to... Figure 7 and Figure 8 The support housing 6 is provided with an elastic edging 7, which is arranged around the bottom opening 622 and extends out of the support housing 6.

[0114] Regarding the connection between the supporting shell 6 and the elastic edging 7, please refer to a specific example. Figure 7 Mounting slots 623 are provided on the circumferential side of the support housing 6. The mounting slots 623 are located near the bottom opening 622. Please refer to [link / reference]. Figure 6 and Figure 10 The elastic edging 7 includes a main body 71 and a mounting part 72. Please refer to the following: Figure 7 and Figure 10 The main body 71 is cylindrical, and the mounting part 72 is located near one end of the main body 71. Please refer to [link / reference]. Figure 6 The main body 71 is inserted into the cavity 621 through the bottom opening 622. The mounting part 72 is located in the mounting strip hole 623. The connecting piece is inserted from the bottom of the support housing 6 and passes through the mounting part 72 to fix the elastic edge 7 to the support housing 6.

[0115] Specifically, please see Figure 7 Two mounting holes 623 are symmetrically provided on the circumferential side of the support housing 6, and the shape of the mounting part 72 matches the shape of the mounting holes 623.

[0116] The elastic edging 7 is made of an elastic material, such as soft rubber. When the lifting structure 4 lowers the supporting housing 6 to the target low position, the elastic edging 7 contacts the ground and is compressed against the ground, undergoing a certain degree of elastic deformation; when the lifting structure 4 raises the supporting housing 6 to the target high position, the elastic edging 7 separates from the ground. Please refer to [link / reference]. Figures 11-12 , Figure 11 and Figure 12 The ground is represented by a horizontal dashed line. Figure 11 This illustrates that the elastic edging 7 has a gap between itself and the ground along the Z-axis direction, i.e. Figure 11 This illustrates the state where the elastic edging 7 is separated from the ground. Figure 12 This illustrates the state of the elastic edging 7 in contact with the ground.

[0117] The support housing 6 provided in this embodiment is provided with an elastic edge 7. When the lifting structure 4 drives the support housing 6 to descend to the target low position, the elastic edge 7 can deform to a certain extent, effectively preventing foreign objects from entering the elastic edge 7 and the cavity 621 of the support housing 6. At the same time, it also plays a role in water storage, so that there is a certain amount of moisture inside the elastic edge 7 and the cavity 621 of the support housing 6, which further improves the cleaning efficiency of stubborn stains.

[0118] Regarding the layout of the second cleaning component 3 and the first cleaning component 2 on the support frame 1, in one embodiment, please refer to [link to previous document]. Figure 1 and Figure 2The cleaning seat 100 includes two roller assemblies 8, both of which are rotatably connected to the support frame 1. The two roller assemblies 8 are arranged at intervals relative to each other along a first direction. The first cleaning component 2 is arranged at intervals with the two roller assemblies 8 along a second direction. The first and second directions are perpendicular to each other. The second cleaning component 3 is disposed between one of the roller assemblies 8 and the first cleaning component 2.

[0119] Please return to the previous page. Figure 1 and Figure 2 Two roller assemblies along 8 Figure 1 The X-axis direction is set at relative intervals, and the direction of the X-axis is the first direction. For details, please refer to [link / reference]. Figure 1 Two roller assemblies along 8 Figure 1 The X-axis is respectively set on both ends of the support frame 1. The first cleaning component 2 and the two roller assemblies 8 are along the X-axis. Figure 1 The Y-axis direction is set at intervals, and the Y-axis direction is the second direction. The first cleaning component 2 and the two roller components 8 are respectively close to the two ends of the cleaning seat 100 along the Y-axis direction.

[0120] Please see Figure 1 An clearance groove 13 is formed on the support frame 1 between two roller assemblies 8. An installation assembly is installed on the clearance groove 13 for connecting to the upright part of the cleaning equipment.

[0121] Regarding the position of the second cleaning component 3 on the support frame 1, the size of the second cleaning component 3 and its position on the support frame 1 should be appropriately determined based on the layout of the components within the support frame 1. Please refer to [link / reference needed]. Figure 2 In the example where the second cleaning component 3 is a roller brush, the axis of the second cleaning component 3 is parallel to the axis of the first cleaning component 2.

[0122] The distribution of the roller assembly 8, the second cleaning assembly 3, and the first cleaning assembly 2 on the support frame 1 provided in this embodiment makes the structure of the cleaning seat 100 compact.

[0123] This embodiment provides a cleaning device, which is a handheld floor scrubber. The cleaning device includes an upright part and a cleaning seat 100 provided in any of the above embodiments. The cleaning seat 100 is hinged to the upright part.

[0124] The cleaning seat 100 contacts the surface to be cleaned to clean it. The cleaning seat 100 is hinged to the upright part. When the cleaning seat 100 is in operation, the upright part is used to move the cleaning seat 100 to clean the surface. Specifically, the cleaning objects of the cleaning equipment include tiles, floors, cement floors, glass surfaces, etc.

[0125] Regarding the upright part, the end of the upright part away from the cleaning seat 100 is a handle assembly, which is used for user operation and gripping.

[0126] The upright part is also equipped with a controller, and the lifting structure 4 of the cleaning seat 100 is connected to the controller; at the same time, an operation interface is also formed on the upright part, and the user can control the working status of the cleaning equipment through the operation interface.

[0127] The upright unit also includes a clean water tank and a wastewater tank. The clean water tank contains cleaning fluid, such as cleaning water, which can be supplied to the first cleaning component 2 and the second cleaning component 3 of the cleaning seat 100 via a clean water pipeline. The wastewater tank is configured to contain recycled wastewater. When cleaning equipment is used to clean the floor, wastewater is generated on the surface being cleaned, and the wastewater can be recycled back to the wastewater tank via a wastewater recycling pipeline.

[0128] The cleaning equipment provided in this embodiment can select different cleaning modes according to different cleaning scenarios. For example, when it is necessary to clean stubborn stains on the floor, the powerful cleaning mode of the cleaning equipment can be activated. When the user selects the powerful cleaning mode, the controller receives a command and controls the lifting structure 4 to move downwards until the second cleaning component 3 contacts the ground. When the second cleaning component 3 reaches the target low position, the controller controls the lifting structure 4 to stop moving. The stubborn stains on the floor are then cleaned by the second cleaning component 3, realizing the powerful cleaning mode of the cleaning equipment. When the powerful cleaning mode is not needed, the user can select the normal cleaning mode. When the user selects the normal cleaning mode, the controller receives a command and controls the lifting structure 4 to move upwards until the second cleaning component 3 separates from the ground. When the second cleaning component 3 reaches the target high position, the controller controls the lifting structure 4 to stop moving. At this time, only the first cleaning component 2 cleans the floor.

[0129] The cleaning device provided in this embodiment, since the second cleaning component 3 only contacts the floor when needed, allows the cleaning seat 100 to clean stubborn stains without affecting the floor or the operation of the cleaning seat due to the second cleaning component 3.

[0130] In one embodiment, the second cleaning component 3 is directly connected to the lifting structure 4. When the second cleaning component 3 is at the target low position, the user pushes the cleaning seat 100 back on the ground via the hand handle assembly to clean stubborn stains on the ground. Alternatively, in another embodiment, the cleaning seat 100 further includes a drive structure 5, which is connected to the second cleaning component 3, and the lifting structure 4 is connected to the drive structure 5. The drive structure 5 is used to drive the second cleaning component 3 to rotate to clean the ground. Alternatively, in another embodiment, the cleaning seat 100 includes a translation drive structure, which is connected to the second cleaning component 3, and the lifting structure 4 is connected to the translation drive structure. The translation drive structure is used to drive the second cleaning component 3 to move to clean the ground.

[0131] When the drive structure 5 can rotate the second cleaning component 3, and the cleaning equipment enters the powerful cleaning mode, the controller controls the lifting structure 4 to move downwards until the second cleaning component 3 contacts the ground. When the second cleaning component 3 reaches the target low position, the controller controls the lifting structure 4 to stop. After detecting that the lifting structure 4 has stopped, the controller controls the drive structure 5 to rotate the second cleaning component 3 to clean stubborn stains on the ground. When the user cancels the powerful cleaning mode, the controller controls the drive structure 5 to stop, and simultaneously controls the lifting structure 4 to move upwards until the second cleaning component 3 separates from the ground. When the second cleaning component 3 reaches the target high position, the controller controls the lifting structure 4 to stop. Alternatively, when the cleaning equipment enters the powerful cleaning mode, the controller controls the lifting structure 4 to move downwards while also controlling the drive structure 5 to move. When the second cleaning component 3 reaches the target low position, the controller controls the lifting structure 4 to stop.

[0132] When the translational drive structure can move the second cleaning component 3, and the cleaning equipment enters the powerful cleaning mode, the controller controls the lifting structure 4 to move downwards until the second cleaning component 3 contacts the ground. When the second cleaning component 3 reaches the target low position, the controller controls the lifting structure 4 to stop. After detecting that the lifting structure 4 has stopped, the controller controls the translational drive structure to move, causing the translational drive structure to move the second cleaning component 3 along... Figure 1 The horizontal reciprocating or translational drive structure along the X-axis can drive the cleaning component 3 along... Figure 1The device moves horizontally back and forth along the Y-axis to clean stubborn stains on the ground. When the user cancels the powerful cleaning mode, the controller stops the translation drive mechanism and simultaneously controls the lifting mechanism 4 to move upwards until the second cleaning component 3 separates from the ground. When the second cleaning component 3 reaches the target high position, the controller stops the lifting mechanism 4. Alternatively, when the cleaning device enters the powerful cleaning mode, the controller controls the lifting mechanism 4 to move downwards while simultaneously controlling the translation drive mechanism. When the second cleaning component 3 reaches the target low position, the controller stops the lifting mechanism 4.
