Description

Technical Field

[0001] This application belongs to the field of smart home technology, and in particular relates to a chassis device, a cleaning base station, and a cleaning system. Background Technology

[0002] The cleaning of the cloths on cleaning robots typically involves the robot returning to the cleaning base station, where the cloths are cleaned. However, the cleaning methods used at the cleaning base station are all unidirectional. Since most cleaning cloths used by cleaning robots are long-pile, unidirectional scraping and washing will cause a large amount of dust to accumulate on the back of the fibers, resulting in poor cleaning effectiveness. Summary of the Invention

[0003] The purpose of this application is to provide a chassis device, a cleaning base station, and a cleaning system to solve the technical problem that the cleaning robot's rag has a poor cleaning effect inside the cleaning base station.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] The first aspect of this application provides a chassis device, including a chassis assembly, a scraping assembly, and a threaded structure. The chassis assembly includes a chassis body and a cleaning disc. The cleaning disc is disposed on the chassis body, and the chassis body or the cleaning disc is connected to the scraping assembly via the threaded structure.

[0006] A limiting structure is formed between the chassis assembly and the scrubbing assembly. The limiting structure is used to limit the range of movement of the scrubbing assembly along the height direction of the chassis assembly.

[0007] When the cloth assembly in the cleaning equipment rotates bidirectionally and moves between low and high positions, the cloth assembly drives the scraping assembly to rotate and rise and fall through the threaded structure.

[0008] In one feasible implementation, the scraping assembly includes a scraping column, the chassis assembly includes a base column, the base column is disposed on the chassis body or the cleaning disc, and the scraping column and the base column are connected by a threaded structure.

[0009] The limiting structure includes a first limiting structure and a second limiting structure, which are respectively formed at opposite ends of the threaded structure along the height direction of the chassis assembly.

[0010] In one feasible implementation, the threaded structure includes a helical groove and a mating protrusion, the mating protrusion being slidable within the helical groove.

[0011] In one feasible implementation, the scraping column includes a connecting column, with a spiral groove formed on the outer circumferential side of the connecting column; the base column has a cylindrical structure, with a protrusion provided on the inner circumferential side of the base column, and the scraping column is inserted into the base column from the free end of the base column.

[0012] In one feasible implementation, one end of the connecting post inserted into the base post is the connecting post insertion end, and the end of the spiral groove away from the connecting post insertion end forms a spiral abutting end face. When the scraping assembly is in the first position, the spiral abutting end face abuts against the mating protrusion to form a first limiting structure.

[0013] In one feasible implementation, the connecting post includes a first section and a second section, the first section and the second section are connected, the first section is provided with a spiral groove, the end of the second section away from the first section is the insertion end of the connecting post, the diameter of the second section is smaller than the diameter of the first section, one end of the spiral groove is close to the end face of the second section, and the second section is provided with a limiting member. When the scraping assembly is in the second position, the limiting member abuts against the mating protrusion to form a second limiting structure.

[0014] In one feasible implementation, the limiting member includes a sleeve and an abutment protrusion, the abutment protrusion being connected to the sleeve, the sleeve being fitted onto the second section, and the abutment protrusion being disposed at one end of the spiral groove near the insertion end of the connecting post.

[0015] In one feasible implementation, there are two or more spiral grooves, and each spiral groove has one or more mating protrusions. The number of abutting protrusions is consistent with the number of spiral grooves, and the abutting protrusions are respectively disposed at the end of the corresponding spiral groove near the insertion end of the connecting post.

[0016] In one feasible implementation, the base column is provided with a base hole, the scraping column is provided with a scraping hole, the scraping column is provided with a connecting column and there is a gap between the connecting column and the scraping hole, the base column is inserted into the scraping hole, and the connecting column is inserted into the base hole.

[0017] A second aspect of this application provides a clean base station, including the chassis device provided by any of the above-described technical solutions.

[0018] A third aspect of this application provides a cleaning system, including a cleaning device and a cleaning base station provided by the above-described technical solution; the cleaning device includes a wiping cloth assembly and a wiping cloth driving assembly, the wiping cloth driving assembly is connected to the wiping cloth assembly, the wiping cloth driving assembly is used to drive the wiping cloth assembly to rotate bidirectionally and move between a low position and a high position, and drives the scraping and washing assembly to move between a first position and a second position through the wiping cloth assembly, the scraping and washing assembly stops rotating at the first position and the second position.

[0019] In one feasible implementation, the rag driving assembly includes a drive motor, a first connector, a second connector, and a rag limiting assembly. The drive motor is driven to the first connector, the first connector and the second connector are threadedly connected, the first connector is fixedly connected to the rag assembly, and the rag limiting assembly is used to limit the movement range of the first connector relative to the second connector in a first direction. The thread helix angle of the threaded structure on the chassis device is greater than the thread helix angle between the first connector and the second connector.

[0020] In one feasible implementation, the thread helix angle of the threaded structure is greater than 1.5 times the thread helix angle between the first connector and the second connector.

[0021] Compared with the prior art, this application includes at least the following beneficial effects:

[0022] In the chassis device provided in this embodiment, the threaded structure between the chassis assembly and the scraping assembly, and the limiting structure between the chassis assembly and the scraping assembly, restrict the upward movement of the scraping assembly to the second position and the downward movement to the first position, thereby achieving the scraping assembly stopping at the second position when rotating in the reverse direction and stopping at the first position when rotating in the forward direction. Furthermore, when the cloth assembly rotates in the reverse direction to the high position, it can drive the scraping assembly to the second position; when the cloth assembly rotates in the forward direction to the low position, it can drive the scraping assembly to the first position. That is, during the process of the cloth assembly moving along the height direction... The scraping component can always be in contact with the cloth component, allowing the cloth component to rotate relative to the scraping component for scraping in both high and low positions. This enables bidirectional cleaning of the cloth component, improving cleaning efficiency and effectiveness. It effectively prevents the cleaning equipment from affecting the cleaning effect on surfaces such as floors due to poor cloth cleanliness, thus enhancing the user experience. In addition, the movement of the scraping component along the height direction is passively driven by the rotation of the cloth component, meaning that no additional drive device is needed for the movement of the scraping component along the height direction, resulting in lower costs.

[0023] The clean base station and clean system provided in this application both include the aforementioned chassis device, and therefore include at least all the beneficial effects of the aforementioned chassis device, which will not be repeated here. Attached Figure Description

[0065] Figure 1 This is a schematic diagram of the chassis device 1 provided in an embodiment of this application. Figure 2 This is a schematic diagram showing the cooperation between the chassis device 1 and the wiping cloth assembly 2 provided in an embodiment of this application. Figure 3 This is an exploded view showing the chassis device 1 and the wiping cloth assembly 2 in cooperation, as provided in this embodiment. Before describing the chassis device 1 provided in this embodiment, for ease of description, the following directions are defined: the chassis device 1 can be calibrated by the following three mutually perpendicular axes: the lateral axis X, the front-rear axis Y, and the vertical axis Z. The vertical axis Z is the direction extending vertically upwards along the bottom surface of the chassis device 1.

[0066] like Figures 1-3 As shown, the chassis device 1 provided in this embodiment includes a chassis assembly 11, a scraping assembly 12, and a threaded structure 13.

[0067] The chassis unit 1 is placed in the cleaning base station, which is used in conjunction with cleaning equipment (such as a cleaning robot). The cleaning base station is used to store cleaning equipment when it is not in use, and to charge the cleaning equipment and clean the cleaning cloths. When the cleaning equipment is stored in the cleaning base station, the cleaning equipment is supported on the chassis unit 1.

[0068] Please see Figure 1 The chassis device 1 provided in this embodiment includes a chassis assembly 11 and a scraping assembly 12. The scraping assembly 12 is disposed on the chassis assembly 11. The chassis assembly 11 is used to support the scraping assembly 12. The scraping assembly 12 is used to clean the wiping cloth assembly 2 of the cleaning equipment. When the cleaning equipment is stored in the cleaning base station, the wiping cloth assembly 2 of the cleaning equipment is located above the scraping assembly 12.

[0069] In existing related technologies, the cleaning schemes used for cleaning cloths in cleaning base stations can only achieve unidirectional cloth cleaning: the cleaning equipment includes a cloth driving component 3 connected to the cloth component 2. When the cloth driving component 3 is working, it can drive the cloth component 2 to rotate. When the cleaning equipment moves into the cleaning base station, the cloth driving component 3 is activated. The cloth driving component 3 can drive the cloth component 2 to rotate in the forward direction and move the cloth component 2 downward. After moving a certain distance to the low position, the cloth driving component 3 can only drive the cloth component 2 to rotate in the forward direction and no longer drive the cloth component 2 to move downward. At this time, the cloth component 2 is in contact with the scraping component 12 on the chassis device 1. The cloth driving component 3 continues to control the cloth component 2 to rotate in the forward direction. The position of the scraping component 12 remains unchanged. The cloth component 2 rotates relative to the scraping component 12 so that the scraping component 12 can scrape and wash the cloth component 2. When the control cloth drive component 3 drives the cloth component 2 to rotate in the opposite direction, the cloth component 2 will rise. After rising to a certain height, it will reach the high position. At the high position, the cloth drive component 3 can only drive the cloth component 2 to rotate in the opposite direction and will no longer drive the cloth component 2 to move upward. Because the cloth component 2 rises after rotating in the opposite direction, it will disengage from the scraping component 12, meaning that the reverse rotation of the cloth component 2 cannot scrape and wash it. Therefore, the cleaning of the cloth component 2 in the cleaning base station can only be done in one direction, which affects the cleaning effect. In particular, since most of the cloth components 2 are made of long fibers, scraping and washing only in one direction will cause a large amount of dust to be trapped on the back of the fibers, resulting in poor cleaning effect.

[0070] Based on the above problems, this embodiment adds a threaded structure 13 between the chassis assembly 11 and the scraping assembly 12, and the chassis assembly 11 and the scraping assembly 12 are connected by the threaded structure 13.

[0071] The chassis assembly 11 and the scraping assembly 12 are connected by a threaded structure 13, meaning that a threaded connection can be achieved between the chassis assembly 11 and the scraping assembly 12. The chassis assembly 11 remains stationary, but when the scraping assembly 12 is rotated, the scraping assembly 12 can move relative to the chassis assembly 11 along the height direction. The height direction is the distribution direction of the scraping assembly 11 and the chassis assembly 12. Please refer to [link / reference]. Figure 3 The scraping assembly 11 and the chassis assembly 12 are distributed along the Z-axis, which is the height direction. In conjunction with the cleaning equipment, when a threaded connection 13 is provided between the chassis assembly 11 and the scraping assembly 12, the operation of the scraping assembly 12 is as follows:

[0072] When the cleaning equipment is located in the cleaning base station equipped with the chassis device 1 provided in this embodiment, if the wiping assembly 2 of the cleaning equipment is in contact with the scraping assembly 12 and there is a certain friction between the two, when the wiping assembly 2 rotates, under the action of the friction between the wiping assembly 2 and the scraping assembly 12, the wiping assembly 2 will drive the scraping assembly 12 to rotate together. For example, when the wiping assembly 2 rotates upward in the opposite direction, the scraping assembly 12 will also rotate upward with the wiping assembly 2, preventing the wiping assembly 2 from separating from the scraping assembly 12 when it rises, thus providing a premise for the wiping assembly 2 to still achieve scraping even when it rotates in the opposite direction.

[0073] Regarding the friction between the scraping assembly 12 and the cloth assembly 2, see Figure 3 Typically, the cloth assembly 2 includes a cloth tray 21 and a cloth 22. The cloth 22 is fixed on the cloth tray 21. The greater the squeezing force between the scraping assembly 12 and the cloth 22, the greater the friction between them. When the friction between the scraping assembly 12 and the cloth 22 is greater than a certain value, the cloth assembly 2 can rotate and drive the scraping assembly 12 to rotate together.

[0074] For a cloth 22 with a certain thickness along its height, such as a long-pile cloth 22, the following situation exists: When the scraping assembly 12 contacts the cloth 22 on the cloth assembly 2 and the distance between the scraping assembly 12 and the cloth tray 21 is d, the friction between the scraping assembly 12 and the cloth 22 is large enough that when the cloth assembly 2 rotates, it can drive the scraping assembly 12 to rotate as well. If the scraping assembly 12 continues to squeeze the cloth assembly 2, that is, further reduces the distance between the scraping assembly 12 and the cloth tray 21, the friction between the scraping assembly 12 and the cloth 22 increases further, making it easier for the cloth assembly 2 to drive the scraping assembly 12 to rotate as well. Therefore, for a cloth 22 with a certain thickness along its height, when the distance between the scraping assembly 12 and the cloth tray 21 is within a certain range, the cloth assembly 2 can drive the scraping assembly 12 to rotate as well when it rotates.

[0075] Since the scraping component 12 is expected to drive the cloth component 2 to rotate while the scraping component 12 does not rotate when the cloth drive component 3 is cleaning the cloth component 2, it is necessary to restrict the rotation of the scraping component 12 relative to the chassis component 11 when the cloth component 2 is driven to the stop position by the cloth drive component 3. In this way, when the cloth component 2 drives the scraping component 12 to the high position or low position of the cloth component 2, the cloth component 2 can rotate while the scraping component 12 does not move, so as to perform bidirectional cleaning of the cloth component 2.

[0076] In this embodiment, a limiting structure is formed between the chassis assembly 11 and the scraping assembly 12. The limiting structure limits the range of movement of the scraping assembly 12 on the chassis assembly 11 along the height direction of the chassis assembly 11. Here, the height direction of the chassis assembly 11 is as follows: Figure 3 The Z-axis shown indicates the orientation of the chassis assembly 11 and the scrubbing assembly 12 along their distribution direction. The limiting structure restricts the movement range of the scrubbing assembly 12 on the chassis assembly 11, meaning the scrubbing assembly 12 has two stopping positions during movement: the first position and the second position. When the scrubbing assembly 12 rotates in the reverse direction, it moves along the height direction towards extending out of the chassis assembly 11, meaning the height of the scrubbing assembly 12 increases. When it reaches the second position, the scrubbing assembly 12 will no longer rotate in the reverse direction. When the scrubbing assembly 12 rotates in the forward direction, it moves along the height direction towards extending into the chassis assembly 11, meaning the height of the scrubbing assembly 12 decreases. When it decreases to the first position, the scrubbing assembly 12 will no longer rotate in the forward direction. The distance between the first and second positions along the height direction is the range of motion of the scrubbing assembly 12 on the chassis assembly 11.

[0077] In this embodiment, the scraping assembly 12 is limited by a limiting structure to move upward to the second position, that is, to stop rotating in the reverse direction at the second position, and to move downward to the first position, that is, to stop rotating in the forward direction at the first position.

[0078] In this embodiment, the movement range of the scraping component 12 corresponds to the movement range of the cloth component 2 in the cleaning device along the height direction. That is, when the cloth component 2 in the cleaning device rotates bidirectionally and moves between a low position and a high position along the height direction, the cloth component 2 can drive the scraping component 12 to move between a first position and a second position. Specifically, when the cloth component 2 rotates in the opposite direction to the high position under the drive of the cloth driving component 3, the cloth component 2 can drive the scraping component 12 to move to the second position; when the cloth component 2 rotates in the forward direction to the low position under the drive of the cloth driving component 3, the cloth component 2 can drive the scraping component 12 to move to the first position.

[0079] When the scraping assembly 12 stops rotating in the reverse direction at the second position, the cloth assembly 2 can continue to rotate in the reverse direction under the drive of the cloth driving assembly 3. When the scraping assembly 12 stops rotating in the forward direction at the first position, the cloth assembly 2 can continue to rotate in the forward direction under the drive of the cloth driving assembly 3, thereby enabling the cloth assembly 2 to rotate relative to the scraping assembly 12 for scraping when in the high position and the low position.

[0080] The chassis device 1 provided in this embodiment performs the following cleaning process on the cleaning cloth assembly 2: When the cleaning equipment returns to the cleaning base station, if the scraping component 12 is in the second position, the cloth assembly 2 can be rotated in the reverse direction first. Since the scraping component 12 remains stationary, it cleans the cloth assembly 2. Then, the cloth assembly 2 is rotated in the forward direction. Under the frictional force between the cloth assembly 2 and the scraping component 12, the scraping component 12 rotates synchronously in the forward direction with the cloth assembly 2. That is, the cloth assembly 2 drives the scraping component 12 to move downward until the cloth assembly 2 descends to the low position and the scraping component 12 is in the first position. Then, the cloth assembly 2 continues to rotate in the forward direction, and the scraping component 12 remains stationary, thus cleaning the cloth assembly 2. The scraping component 12 squeezes the cloth assembly 2, removing debris from the cloth assembly 2 in a timely manner during its rotation, thereby cleaning the cloth assembly 2. In addition, the cloth assembly 2 can be rotated forward and backward repeatedly to achieve bidirectional cleaning of the cloth assembly 2 multiple times.

[0081] When cleaning the cloth assembly 2 of the cleaning equipment for the first time, the scraping component 12 can be in the second position as described above, or it can be in the first position. Of course, the scraping component 12 can also be in a position between the first and second positions. For example, when cleaning the cloth assembly 2 of the cleaning equipment for the first time, the scraping component 12 is in the first position. When the cleaning equipment returns to the cleaning base station, the cloth driving component 3 can be controlled to rotate the cloth assembly 2 forward to the low position. The cloth assembly 12 is cleaned when it is in the low position and the scraping component 12 is in the first position. Then, the cloth driving component 3 can be controlled to rotate the cloth assembly 2 in the opposite direction. The cloth assembly 12 is cleaned when it is in the high position and the scraping component 12 is in the second position.

[0082] When the cleaning equipment leaves the base station, the cloth driving assembly 3 drives the cloth assembly 2 to a high position. At this time, the cloth assembly 2 is in contact with the second position. Because the scraping assembly 12 is in the second position, it has some impact on the cleaning equipment leaving the cleaning base station. However, under the drive of the driving device, the cleaning equipment can still overcome the resistance between the cloth assembly 2 and the scraping assembly 12 and leave the cleaning base station. When the cleaning equipment returns to the cleaning base station, because the scraping assembly 12 is in the second position, it has some impact on the cleaning equipment being stored inside the cleaning base station. However, under the drive of the driving device, the cleaning equipment can still overcome the resistance between the cloth assembly 2 and the scraping assembly 12 and return to the cleaning base station.

[0083] As described above, for a cloth 22 with a certain thickness along its height, when the distance between the scraping assembly 12 and the cloth tray 21 of the cloth assembly 2 is within a certain range, the cloth assembly 2 can rotate to drive the scraping assembly 12 to rotate as well. Therefore, when the cloth 22 has a certain thickness along its height, the following three scenarios exist for the first and second positions of the scraping assembly 12, as well as the low and high positions of the cloth assembly 2:

[0084] Scenario 1: When the cloth assembly 2 is in the low position and the scraping assembly 12 is in the first position, when the cloth assembly 2 is rotated in the opposite direction to the high position, the scraping assembly 12 will also rotate to the second position.

[0085] Scenario 2: When the cloth assembly 2 is in the low position and the scraping assembly 12 is in the first position, rotating the cloth assembly 2 in the reverse direction to the high position, at this time, the scraping assembly 12 has not yet moved to the second position. Rotating the cloth assembly 2 in the reverse direction again can drive the scraping assembly 12 to move to the second position. That is, when the cloth assembly 2 is in the high position, the scraping assembly 12 can continue to rotate in the reverse direction to squeeze the cloth 22 on the cloth assembly 2 until it moves to the second position. When the cloth assembly 2 is rotated in the forward direction, it drives the scraping assembly 12 to rotate in the forward direction. When the cloth assembly 2 is rotated to the low position, at this time, the scraping assembly 12 has not yet moved to the first position. Rotating the cloth assembly 2 in the forward direction again can drive the scraping assembly 12 to move to the first position. That is, when the cloth assembly 2 is in the low position, the scraping assembly 12 continues to rotate in the forward direction to reduce the squeezing of the cloth 22 on the cloth assembly 2 until it moves to the first position.

[0086] Scenario 3: When the cloth assembly 2 is in the low position and the scraping assembly 12 is in the first position, the cloth assembly 2 is rotated in the reverse direction. Before the cloth assembly 2 reaches the high position, the scraping assembly 12 has already moved to the second position. Rotating the cloth assembly 2 in the reverse direction again will allow it to reach the high position. That is, when the scraping assembly 12 reaches the second position, the cloth assembly 2 rotates in the reverse direction to reduce the pressure of the scraping assembly 12 on the cloth assembly 2 until the cloth assembly 2 reaches the high position. Then, the cloth assembly 2 rotates forward, causing the scraping assembly 12 to rotate forward. Before the cloth assembly 2 reaches the low position, the scraping assembly 12 has already moved to the first position. Rotating the cloth assembly 2 in the forward direction again will allow it to reach the low position. That is, when the scraping assembly 12 reaches the first position, the cloth assembly 2 rotates in the forward direction to increase the pressure of the scraping assembly 12 on the cloth assembly 2 until the cloth assembly 2 reaches the low position.

[0087] The above three scenarios are mainly due to the relationship between the number of rotations of the scraping component 12 from the first position to the second position and the number of rotations of the cloth component 2 from the low position to the high position. In scenario one, the number of rotations of the scraping component 12 from the first position to the second position is the same as the number of rotations of the cloth component 2 from the low position to the high position; in scenario two, the number of rotations of the scraping component 12 from the first position to the second position is greater than the number of rotations of the cloth component 2 from the low position to the high position; and in scenario three, the number of rotations of the scraping component 12 from the first position to the second position is less than the number of rotations of the cloth component 2 from the low position to the high position.

[0088] Preferably, the number of rotations of the scraping assembly 12 from the first position to the second position is the same as the number of rotations of the wiping cloth assembly 2 from the low position to the high position. However, considering processing errors, scenarios two and three may also occur.

[0089] In addition, in this embodiment, it is preferable that the height of the scraping component 12 rising in one rotation is not less than the height of the cloth component 2 rising in one rotation. When the cloth component 2 rotates upward in the opposite direction, it drives the scraping component 12 to rotate in the opposite direction as well. If the height of the scraping component 12 rising in one rotation is greater than the height of the cloth component 2 rising in one rotation, the scraping component 12 increasingly squeezes the cloth component 2, gradually increasing the friction between them, which in turn helps the cloth component 2 to drive the scraping component 12 upward. Furthermore, since the scraping component 12 increasingly squeezes the cloth component 2 when it rotates in the opposite direction, it also helps the cloth component 2 to better remove debris during the reverse rotation when the scraping component 12 is in the second position, achieving a better cleaning effect.

[0090] In summary, the chassis device 1 provided in this embodiment restricts the upward movement of the scraping assembly 12 to the second position and the downward movement to the first position through the threaded structure 13 between the chassis assembly 11 and the scraping assembly 12, and through the limiting structure between the chassis assembly 11 and the scraping assembly 12, thereby achieving the scraping assembly 12 stopping at the second position when rotating in the reverse direction and stopping at the first position when rotating in the forward direction. Furthermore, when the cloth assembly 2 rotates in the reverse direction to the high position, it can drive the scraping assembly 12 to move to the second position; when the cloth assembly 2 rotates in the forward direction to the low position, it can drive the scraping assembly 12 to move to the first position. That is, when the cloth assembly 2 rotates along the high position... During the vertical movement, the scraping component 12 remains in constant contact with the cloth component 2, allowing the cloth component 2 to rotate relative to the scraping component 12 for scraping when in high and low positions. This enables bidirectional cleaning of the cloth component 2, improving cleaning efficiency and effectiveness. It effectively prevents poor cloth cleanliness from affecting the cleaning effect on surfaces such as floors, thus enhancing the user experience. Furthermore, the vertical movement of the scraping component 12 is passively driven by the rotation of the cloth component 2, eliminating the need for additional drive devices and reducing costs.

[0091] In this embodiment, when the scraping assembly 12 scrapes the rotating cloth assembly 2, water can be injected onto the cloth assembly 2 to facilitate the scraping and cleaning of the cloth assembly 2. Water can be injected onto the cloth assembly 2 in the following two ways: one is to inject water into the cloth assembly 2 through the water supply device of the cleaning equipment; the other is to spray water onto the cloth assembly 2 through the water spraying assembly on the chassis device 1.

[0092] For information on injecting water into the cloth assembly 2 via the water supply device of the cleaning equipment, please refer to [link to relevant documentation]. Figure 3 The diagram illustrates that the cloth tray 21 of the cloth assembly 2 has a perforation 211. A water supply device is installed within the cleaning equipment. When the water supply device is activated, clean water within the cleaning equipment flows through the perforation 211 to the cloth 22, thus wetting the cloth 22. For example, when the cloth assembly 2 is in the low position and the scraping component 12 is in the first position, the water supply device can be activated to wet the cloth 22, enabling cleaning when the cloth assembly 2 rotates forward; when the cloth assembly 2 is in the high position and the scraping component 12 is in the second position, the water supply device can be activated to wet the cloth 22, enabling cleaning when the cloth assembly 2 rotates in the reverse direction. Regarding the perforation 211, in... Figure 3 In the example, there are multiple holes 211, which are evenly spaced along the circumferential direction of the cloth tray 21.

[0093] Regarding the spraying of water onto the cloth assembly 2 via the water spraying assembly on the chassis device 1, specifically, a water spraying assembly can be installed on the chassis device 1. The water spraying assembly includes a nozzle. When the cleaning equipment is stored in the cleaning base station, the nozzle is located directly below the cloth assembly 2. When the cloth assembly 2 is in the low position and the scraping assembly 12 is in the first position, the water spraying assembly can be activated to wet the cloth 22, thus achieving cleaning when the cloth assembly 2 rotates in the forward direction. When the cloth assembly 2 is in the high position and the scraping assembly 12 is in the second position, the water spraying assembly can be activated to wet the cloth 22, thus achieving cleaning when the cloth assembly 2 rotates in the reverse direction.

[0094] The water spray assembly also includes a water pump, which is connected to the water tank of the cleaning base station via a pipe, and the nozzles are connected to the water pump via pipes.

[0095] In one specific example, the nozzle is fixed in position on the chassis device 1, meaning the nozzle is fixed to the chassis device 1. In another specific example, the height of the nozzle is adjustable. For example, when the wiping assembly 2 rotates in the opposite direction, causing the scraping assembly 12 to move upwards, the nozzle also rises, so that when the wiping assembly 2 is in the high position and the scraping assembly 12 is in the second position, the nozzle remains close to the wiping assembly 2. For the nozzle height to be adjustable, the nozzle can be connected to a linear drive structure, which can be a cylinder or a hydraulic cylinder, driving the nozzle to move along the height direction.

[0096] Please see Figures 4-6 , Figure 4 This is an exploded view of the chassis device 1 provided in the embodiments of this application. Figure 5 A top view of the chassis device 1 provided in an embodiment of this application; Figure 6 for Figure 5 Schematic diagram of the sectional view along the AA direction.

[0097] In one embodiment, please refer to Figure 4 The scraping assembly 12 includes a scraping column 121, and the chassis assembly 11 includes a base column 113. Please refer to [link / reference]. Figure 6 The scraping column 121 and the base column 113 are connected by a threaded structure 13.

[0098] In this embodiment, the scraping column 121 and the base column 113 are threadedly connected to achieve the threaded connection between the scraping assembly 12 and the chassis assembly 11. The structure is simple and simplifies the structure of the chassis device 1.

[0099] Regarding the mating relationship between the scraping column 121 and the base column 113, in one example, the scraping column 121 is inserted into the base column 113, and in another example, the base column 113 is inserted into the scraping column 121.

[0100] When the base column 113 is inserted into the scraping column 121, for example, the outer peripheral side of the base column 113 is a smooth curved surface; or, see Figure 4 The surface of the base column 113 is a non-smooth curved surface; specifically, see [link to relevant documentation]. Figure 4 A base protrusion 1133 is formed on the base column 113, and the base protrusion 1133 is distributed on the base column 113 in the circumferential direction. In this embodiment, the outer circumferential side of the base column 113 is not specifically limited, as long as the scraping column 121 can rotate relative to the base column 113.

[0101] Please see Figures 7-8 ; Figure 7 An exploded view of the chassis assembly 11 provided in an embodiment of this application; Figure 8 This is a schematic diagram of the scraping assembly 12 provided in an embodiment of this application.

[0102] Regarding chassis component 11, in one instance, please refer to Figure 7 The chassis assembly 11 includes a chassis body 111 and a cleaning plate 112. A base column 113 is provided on the chassis body 111, and a clearance hole 114 is provided on the cleaning plate 112. The cleaning plate 112 is provided on the chassis body 111, and the base column 113 passes through the clearance hole 114.

[0103] The chassis body 111 is supported on the main body of the cleaning base station (the main body is the structure of the cleaning base station excluding the base device), and the cleaning tray 112 is supported on the chassis body 111. A cleaning tank is formed within the cleaning tray 112, which can be used to hold wastewater to facilitate the cleaning of the cloth assembly 2 by the scraping component 12. Of course, a drain outlet is also provided on the cleaning tray 112. In this embodiment, the specific shapes of the chassis body 111 and the cleaning tray 112 are not limited.

[0104] In another embodiment, the chassis assembly 11 includes a chassis body 111 and a cleaning plate 112. The cleaning plate 112 is disposed on the chassis body 111, and a base column 113 is disposed on the cleaning plate 112.

[0105] For the scraping assembly 12, in one example, please refer to Figure 8 The scraping assembly 12 also includes a scraping structure 123 and a plurality of supports 122. The plurality of supports 122 are distributed at intervals along the circumferential direction of the scraping column 121 at one end of the scraping column 121 away from the chassis assembly 11. Each support 122 has a scraping structure 123 distributed on the side away from the chassis assembly 11.

[0106] In this embodiment, "multiple supports 122" refers to two or more supports 122. Preferably, the scraping assembly 12 includes multiple supports 122. However, while one support 122 can also clean the cloth assembly 2, using multiple supports 122 achieves a better cleaning effect. For example, the scraping assembly 12 may include three or four supports 122, and the supports 122 may be elongated. Please refer to [link to previous text]. Figure 8 The diagram illustrates that the scraping assembly 12 includes three supports 122, which are evenly spaced on the scraping column 121.

[0107] For example, the bracket 122 and the scraping column 121 are integrally formed; or, the bracket 122 is detachably fixed to the scraping column 121 by means of a connector.

[0108] For the scraping structure 123, by example, the scraping structure 123 is teeth or protrusions distributed on the support 122, or the scraping structure 123 is bristles. When the scraping structure 123 is teeth or protrusions distributed on the support 122, it is preferable that the support 122 and the scraping structure 123 are integrally formed. Please refer to... Figure 8 The diagram illustrates that the scraping structure 123 consists of protrusions distributed on the support 122.

[0109] Please see Figure 8 The end of the scraping column 121 away from the chassis assembly 11 is the upper end surface 124. The scraping structure 123 is higher than the upper end surface 124 of the scraping column 121. When the scraping assembly 12 abuts against the cloth assembly 2, the scraping structure 123 contacts the cloth assembly 2.

[0110] When the cloth assembly 2 rotates relative to the scraping assembly 12, the scraping structure 123 can effectively brush off the dirt adhering to the cloth, reduce the amount of dirt adhering, and improve the cleaning efficiency of the cloth.

[0111] In one example, the chassis assembly 11 is provided with two scraping components 12, each of which is connected to the chassis assembly 11 via a threaded structure 12, and each scraping component 12 forms a limiting structure with the chassis assembly 11. This is suitable for cleaning equipment with two cloth assemblies 2. In another example, the chassis assembly 11 is provided with one scraping component 12, which is suitable for cleaning equipment with one cloth assembly 2. That is, the number of scraping components 12 on the chassis assembly 11 can be reasonably set according to the actual situation.

[0112] In an embodiment based on the scraping assembly 12 including the scraping column 121 and the chassis assembly 11 including the base column 113, the limiting structure includes a first limiting structure and a second limiting structure, which are respectively formed at opposite ends of the threaded structure 13 along the height direction of the chassis assembly 11.

[0113] The first limiting structure is used to limit the scraping assembly 12 to a first position, that is, when the scraping assembly 12 rotates forward to the first position, the first limiting structure restricts the scraping assembly 12 from continuing to rotate forward; the second limiting structure is used to limit the scraping assembly 12 to a second position, that is, when the scraping assembly 12 rotates backward to the second position, the second limiting structure restricts the scraping assembly 12 from continuing to rotate backward.

[0114] For example, the first limiting structure and the second limiting structure can be set to the same structure or different structures.

[0115] See Figures 9-14 , Figure 9 A schematic diagram of the chassis assembly 11 provided in an embodiment of this application; Figure 10 for Figure 9 A magnified view of a section at point B in the middle; Figure 11 This is a top view of the cleaning scraper assembly 12 provided in an embodiment of this application; Figure 12 for Figure 11 Schematic diagram of the BB-direction section; Figure 13 A cross-sectional view showing the engagement of the spiral groove 131 and the mating protrusion 132; Figure 14 A cross-sectional view of the scraping assembly 12 in the first position.

[0116] Regarding the threaded structure 13, in one embodiment, please refer to... Figure 10 and Figure 12 The threaded structure 13 includes a helical groove 131 and a mating protrusion 132. The mating protrusion 132 is located in the helical groove 131 and can slide within the helical groove 131.

[0117] The mating protrusion 132 provided in this embodiment is not limited to being spiral in shape, which makes the structure simple and easy to process while realizing the threaded connection between the scraping column 121 and the base column 113.

[0118] For example, the scraping column 121 is provided with a spiral groove 131, and the base column 113 is provided with a mating protrusion 132; or, the scraping column 121 is provided with a mating protrusion 132, and the base column 113 is provided with a spiral groove 131.

[0119] The spiral groove 131 is spiral in shape. The spiral angle and the number of spiral turns of the spiral groove 131 need to be set reasonably according to the cooperation with the cloth assembly 2.

[0120] In an example where a spiral groove 131 is provided on the scraping column 121 and a mating protrusion 132 is provided on the base column 113, in a specific example, a spiral groove 131 is provided on the scraping column 121, and there is one or more mating protrusions 132. The mating protrusions 132 are mated to the spiral groove 131 along the length direction. When there is one mating protrusion 132, it is preferable that the length of the mating protrusion 132 is close to the length of one turn of the spiral groove 131 or the length of the mating protrusion 132 is greater than the length of one turn of the spiral groove 131. When there are two or more mating protrusions 132, the multiple mating protrusions 132 are distributed along the extension direction of the spiral groove 131. In another specific example, the scraping column 121 is provided with two or more spiral grooves 131, and each spiral groove 131 is respectively associated with one or more mating protrusions 132. For example, the scraping column 121 is provided with two spiral grooves 131, and at the same time, the base column 113 is provided with two mating protrusions 132 along the circumferential direction. Each mating protrusion 132 is located in the corresponding spiral groove 131, so as to facilitate the stable connection between the scraping column 121 and the base column 113.

[0121] For example, the cross-sectional shape of the mating protrusion 132 is triangular, or the cross-sectional shape of the mating protrusion 132 is trapezoidal.

[0122] In one embodiment, please refer to Figure 13 The scraping column 121 includes a connecting column 1212, and a spiral groove 131 is formed on the outer peripheral side of the connecting column 1212. The base column 113 has a cylindrical structure, and a protrusion 132 is provided on the inner peripheral side of the base column 113. The scraping column 121 is inserted into the base column 113 from its free end. Please refer to [link to relevant documentation]. Figure 13 ,exist Figure 13 In the middle, the free end of the base column 113 is the upper end face of the base column 113.

[0123] See Figure 12 and Figure 13 ,by Figure 10 Taking the direction of rotation of the spiral groove 131 as an example, when the scraping column 121 rotates counterclockwise, the scraping column 121 moves upward along the height direction; when the scraping column 121 rotates clockwise, the scraping column 121 moves downward along the height direction.

[0124] In an embodiment based on the scraping column 121 including the connecting column 1212, in one embodiment, see... Figure 13The base column 113 is provided with a base hole 1131, the scraping column 121 is provided with a scraping hole 1211, the scraping column 121 is provided with a connecting column 1212 and there is a gap between the connecting column 1212 and the inner wall of the scraping hole 1211, the base column 113 is inserted into the scraping hole 1211 and the connecting column 1212 is inserted into the base hole 1131.

[0125] The structure of the scraping column 121 provided in this embodiment can protect the threaded structure 13 between the base column 113 and the scraping column 121, preventing impurities from entering the threaded structure 13 and affecting the movement of the scraping column 121 relative to the base column 113 in the height direction.

[0126] For example, the outer peripheral side of the base column 113 is in contact with the hole wall of the scraping hole 1211 (the inner side of the scraping column 121) to prevent impurities from entering the threaded structure 13; or, there is a gap between the outer peripheral side of the base column 113 and the hole wall of the scraping hole 1211.

[0127] Please see Figure 12 and Figure 13 ,exist Figure 12 and Figure 13 In the example shown, steps are formed on the outer circumferential surface of the scraped column 121; steps are also formed on the inner circumferential surface of the scraped column 121, and the steps on the scraped column 121 can be called scraped steps 1215; see also Figure 13 A step is formed on the outer circumferential surface of the base column 113, which can be referred to as the base step 1134. When the scraping column 121 is in the first position, the scraping step 1215 on the inner circumferential surface of the scraping column 121 is in contact with the base step 1134 on the outer circumferential surface of the base column 113; or, the scraping step 1215 on the inner circumferential surface of the scraping column 121 is not in contact with the base step 1134 on the outer circumferential surface of the base column 113.

[0128] In one specific embodiment, please refer to Figure 13 The connecting column 1212 is provided with a guide hole 1213, and a guide column 1132 is provided inside the base column 113. The guide column 1132 is inserted into the guide hole 1213.

[0129] By inserting the guide post 1132 into the guide hole 1213, the scraping post 121 is assembled onto the base post 113, and the scraping post 121 is guided to move along the height direction.

[0130] Regarding the first limiting structure, in one embodiment, please refer to... Figure 12 and Figure 13One end of the connecting post 1212 inserted into the base post 113 is the connecting post insertion end 1214. The end of the spiral groove 131 away from the connecting post insertion end 1214 forms a spiral abutting end face 133. When the scraping assembly 12 is in the first position, the spiral abutting end face 133 abuts against the mating protrusion 132 to form a first limiting structure.

[0131] Please see Figure 12 This illustrates the end of the spiral groove 131 furthest from the scraper insertion end 1214, i.e., the spiral abutment end face 133. When the connecting post 1212 rotates and moves downwards in the forward direction, if the end face of the mating protrusion 132 contacts the spiral abutment end face 133, as... Figure 13 As shown, if the connecting column 1212 continues to rotate in the forward direction, the connecting column 1212 cannot continue to rotate because the mating protrusion 132 abuts against the spiral abutting end face 133. That is, the scraping assembly 12 cannot continue to rotate, thus realizing the formation of the first limiting structure by the mating protrusion 132 and the spiral abutting end face 133.

[0132] For example, please see Figure 13 The protrusion 132 is provided on the upper surface of the base column 113 near the base column 113, so as to ensure that the movement range of the scraping assembly 12 matches the movement range of the cloth assembly 2 in the cleaning equipment along the height direction, while reducing the length of the base column 113 along the height direction.

[0133] The first limiting structure provided in this embodiment is simple in structure, which can be achieved by one end of the spiral groove 131 cooperating with the mating protrusion 132.

[0134] Regarding the first limiting structure, in another embodiment, when the scraping assembly 12 rotates forward and moves downward, the scraping column 121 abuts against the chassis assembly 11, or the guide column 1132 inside the base column 113 abuts against the scraping column 121, preventing the base column 113 from continuing to rotate downward (at this time, in the first position, the cooperating protrusion 132 has not yet rotated to the end of the spiral groove 131), thus stopping the forward rotation of the scraping assembly 12 at the first position. Please refer to [link to previous text]. Figure 12 and Figure 13 Alternatively, the scraping step 1215 on the inner side of the scraping column 121 can contact the base step 1134 on the outer side of the base column 113, preventing the base column 113 from continuing to rotate downwards, thus stopping the forward rotation of the scraping assembly 12 at the first position.

[0135] Regarding the second limiting structure, in one embodiment, please refer to... Figure 12 and Figure 13The connecting column 1212 includes a first section 12121 and a second section 12122. The first section 12121 is connected to the second section 12122. A spiral groove 131 is provided on the first section 12121. The end of the second section 12122 away from the first section 12121 is the scraper insertion end 1214. The diameter of the second section 12122 is smaller than the diameter of the first section 12121. The spiral groove 131 is close to the end face of the first section 12121 close to the second section 12122. A limiting member 14 is sleeved on the second section 12122. When the scraping assembly 12 is in the second position, the limiting member 14 abuts against the mating protrusion 132 to form a second limiting structure.

[0136] In this embodiment, when the limiting member 14 is not provided, the reverse rotation of the scraping assembly 12, in conjunction with the protrusion 132, will cause the spiral groove 131 to rotate out; see also Figure 14 By setting the limiting member 14, when the scraping assembly 12 is in the second position, the limiting member 14 abuts against the mating protrusion 132, so that the scraping assembly 12 rotates in the opposite direction and stops in the second position.

[0137] Please see Figure 12 The first segment 12121 is provided with a spiral groove 131, and due to the spiral groove 131 on the first segment 12121, a spiral rib 12123 will be formed on the first segment 12121. The diameter of the second segment 12122 is smaller than the diameter of the first segment 12121. For example, the diameter of the second segment 12122 can be set to be equal to the diameter of the bottom surface of the spiral groove 131.

[0138] The second limiting structure provided in this embodiment is simple in structure and easy to process.

[0139] Regarding the second limiting structure, in another embodiment, it is the same as the first limiting structure, with the end of the spiral groove 131 near the insertion end 1214 of the connecting post abutting against the mating protrusion 132 to form the second limiting structure.

[0140] In an embodiment where a limiting member 14 is provided on a connecting post 1212, in one embodiment, the limiting member 14 includes a sleeve 142 and an abutting protrusion 141. The abutting protrusion 141 is connected to the sleeve 142, the sleeve 142 is fitted on the second section 12122, and the abutting protrusion 141 is disposed at one end of the spiral groove 131 near the insertion end 1214 of the connecting post.

[0141] See Figure 12 This illustrates an abutment protrusion 141 located at one end of the spiral groove 131 near the scraper insertion end 1214. Figure 14The connecting column 1212 continues to rotate in the opposite direction. Since the abutting protrusion 141 abuts against the mating protrusion 132, the connecting column 1212 is restricted from continuing to rotate in the opposite direction. In this embodiment, the abutting protrusion 141 is provided at one end of the spiral groove 131 near the scraper insertion end 1214 to achieve the limiting effect. The structure is simple and easy to process.

[0142] Please compare. Figure 13 and Figure 14 , Figure 13 and Figure 14 The diagram illustrates the two positional states of the scraping component 12. Figure 13 In the middle, the end face of the protrusion 132 contacts the spiral abutment end face 133, at which time the scraping assembly 12 is in the first position; Figure 14 In the middle, the abutting protrusion 141 on the limiting member 14 abuts against the mating protrusion 132, at which time the scraping assembly 12 is in the second position.

[0143] When there is one spiral groove 131, the number of mating protrusions 132 can be set to more than one, and the number of abutting protrusions 141 on the sleeve 142 is consistent with the number of spiral grooves 131. Taking three mating protrusions 132 as an example, the three mating protrusions 132 are the first mating protrusion, the second mating protrusion, and the third mating protrusion. The first mating protrusion, the second mating protrusion, and the third mating protrusion are distributed sequentially along the extension direction of the spiral groove 131, and from the first mating protrusion to the third mating protrusion, the extension direction of the first mating protrusion, the second mating protrusion, and the third mating protrusion gradually downwards. At this time, when the scraping assembly 12 is in the first position, one end of the first mating protrusion abuts against the spiral abutting end face 133; when the scraping assembly 12 is in the second position, one end of the third mating protrusion abuts against the abutting protrusion 141 on the limiting member 14.

[0144] When there are two or more spiral grooves 131, each spiral groove 131 has one or more mating protrusions 132. The number of abutting protrusions 141 on the sleeve 142 is consistent with the number of spiral grooves 131. The abutting protrusions 141 are respectively set at the end of the corresponding spiral groove 131 near the insertion end 1214 of the connecting post. For example, taking three spiral grooves 131 as an example, the three spiral grooves 131 are the first spiral groove, the second spiral groove, and the third spiral groove. The first spiral groove, the second spiral groove, and the third spiral groove are each mated with a mating protrusion 132. The first spiral groove, the second spiral groove, and the third spiral groove are all formed with spiral abutting end faces 133. When the scraping component 12 is in the first position, the three mating protrusions 132 are in contact with the spiral abutting end faces 133 of the first spiral groove, the second spiral groove, and the third spiral groove, respectively. When the scraping component 12 is in the second position, the three mating protrusions 132 are in contact with the three abutting protrusions 141, respectively.

[0145] For example, the limiting member 4 is tightly fitted or attached to the second section 12122; or, the limiting member 4 is tightly fitted or attached to the first section 12121, for example, the limiting member 4 is tightly fitted to the first section 12121 by means of the abutment protrusions 141 distributed along its circumferential direction.

[0146] This embodiment provides a clean base station, including the chassis device 1 provided in any of the above embodiments.

[0147] The chassis device 1 is used in the cleaning base station. The cleaning base station is used in conjunction with cleaning equipment (such as cleaning robots). The cleaning base station is used to store the cleaning equipment when it is not in use, and to charge the cleaning equipment and clean the cleaning cloth.

[0148] This embodiment provides a cleaning system, including a cleaning device and a cleaning base station; the cleaning device includes a wiping cloth assembly 2 and a wiping cloth driving assembly 3, the wiping cloth driving assembly 3 is connected to the wiping cloth assembly 2, the wiping cloth driving assembly 3 is used to drive the wiping cloth assembly 2 to rotate bidirectionally and move between a low position and a high position, and drive the scraping and washing assembly 12 to move between a first position and a second position through the wiping cloth assembly 2, the scraping and washing assembly 12 stops rotating at the first position and the second position.

[0149] The reverse rotation of the wiping assembly 2 can drive the scraping assembly 12 on the chassis device 1 to rotate and rise together. When the wiping assembly 2 reaches the high position, it can reach the second position under the drive of the scraping assembly 12. The scraping assembly 12 stops rising and reverses at the second position, and the wiping assembly 2 continues to rotate in the reverse direction to achieve reverse cleaning. The forward rotation of the wiping assembly 2 can drive the scraping assembly 12 to rotate and fall together in the forward direction. When the wiping assembly 2 reaches the low position, it can reach the first position under the drive of the scraping assembly 12. The scraping assembly 12 stops falling and rotates in the forward direction at the first position, and the wiping assembly 2 continues to rotate in the forward direction to achieve forward cleaning.

[0150] The cleaning equipment may be a floor scrubber, a sweeping robot, a mopping robot, etc., and this application does not limit the scope of the embodiments.

[0151] The cleaning system provided in this embodiment can achieve bidirectional cleaning of the cloth component 2, improving the cleaning efficiency and effect of the cloth. This effectively avoids the cleaning effect of the cleaning equipment on the surface to be cleaned, such as the floor, due to poor cloth cleanliness, thereby improving the user experience.

[0152] Please see Figures 15-18 , Figure 15 A cross-sectional schematic diagram of the base device 1, the cloth assembly 2, and the cloth driving assembly 3 provided in the embodiments of this application; Figure 16 for Figure 15 A magnified view of a section at point C; Figure 17A schematic diagram of the cloth driving component 3 provided in an embodiment of this application; Figure 18 This is a schematic diagram of the internal structure of the cloth driving component 3 provided in an embodiment of this application.

[0153] In one embodiment, please refer to Figures 15-18 The rag driving assembly 3 includes a housing 31, a drive motor 32, a first connector 34, a second connector 35, and a rag limiting assembly. The drive motor 32 is connected to the first connector 34 in a transmission manner. The first connector 34 and the second connector 35 are threadedly connected. The second connector 35 is also connected to the housing 31. The first connector 34 is connected to the rag assembly 2. The rag limiting assembly is used to limit the range of movement of the first connector 34 relative to the second connector 35 in the height direction. The thread helix angle of the thread structure 13 on the chassis device 1 is greater than the thread helix angle between the first connector 34 and the second connector 35.

[0154] Please see Figure 15 and Figure 16 The first connecting member 34 is fixedly connected to the wiping cloth assembly 2. Therefore, the movement of the first connecting member 34 is consistent with that of the wiping cloth assembly 2. Regarding the first connecting member 34 and the second connecting member 35, when the first connecting member 34 rotates forward to the low position, the first connecting member 34 rotates forward again, and the first connecting member 34 and the second connecting member 35 rotate together; when the first connecting member 34 rotates in the opposite direction to the high position, the first connecting member 34 rotates in the opposite direction again, and the first connecting member 34 and the second connecting member 35 rotate together; when the first connecting member 34 rotates in the opposite or forward direction and moves along the height direction, the second connecting member 35 remains stationary, so that the first connecting member 34 can move relative to the second connecting member 35 within a certain range along the height direction.

[0155] In this embodiment, the helix angle of the thread structure 13 on the chassis device 1 is greater than the helix angle between the first connector 34 and the second connector 35. The helix angle is the angle between the tangent to the helix and a plane perpendicular to the thread axis.

[0156] In one scenario, if the number of thread turns of the threaded structure 13 is consistent with the number of thread turns between the first connector 34 and the second connector 35, that is, when the wiping assembly 2 moves to the low position, the scraping assembly 12 is in the second position; when the wiping assembly 2 moves to the high position, the scraping assembly 12 is in the first position, then the thread helix angle of the threaded structure 13 on the chassis device 1 is set to be greater than the thread helix angle between the first connector 34 and the second connector 35. The cooperation process between the scraping assembly 12 and the wiping assembly 2 is as follows: when the wiping assembly 2 is in the low position and the scraping assembly 12 is in the second position, the wiping drive assembly 3 is driven to move the wiping assembly. 2. Reverse rotation: The cloth assembly 2 drives the scraping assembly 12 to rotate in the opposite direction. Since the thread helix angle of the thread structure 13 on the chassis device 1 is greater than the thread helix angle between the first connector 34 and the second connector 35, the height that the scraping assembly 12 rises after one rotation is greater than the height that the cloth assembly 2 rises after one rotation. Therefore, as the cloth assembly 2 drives the scraping assembly 12 to rotate in the opposite direction, the scraping assembly 12 increasingly squeezes the cloth assembly 2, which gradually increases the friction between the two. This is beneficial for the cloth assembly 2 to drive the scraping assembly 12 to rise until the cloth assembly 2 rises to the high position. At this time, the scraping assembly 12 also rises to the first position.

[0157] In this embodiment, by setting the thread helix angle of the thread structure 13 on the chassis device 1 to be greater than the thread helix angle between the first connector 34 and the second connector 35, it is beneficial for the wiping assembly 2 to drive the scraping assembly 12 to rotate together.

[0158] In one specific embodiment, the thread helix angle of the threaded structure 13 on the chassis device 1 is greater than 1.5 times the thread helix angle between the first connector 34 and the second connector 35.

[0159] By setting the thread helix angle of the thread structure 13 on the chassis device 1 to be greater than 1.5 times the thread helix angle between the first connector 34 and the second connector 35, the wiping cloth assembly 2 can stably drive the scraping assembly 12 to rotate together.

[0160] Regarding the cloth driving component 3, in one specific embodiment, please refer to... Figures 16-18 The rag drive assembly 3 also includes an intermediate transmission structure 33. A drive motor 32 is disposed on one side of the housing 31. The drive motor 32 is connected to the first connecting member 34 via the intermediate transmission structure 33. The second connecting member 35 is positioned on the housing 31. (See also...) Figure 16 The first connector 34 is threadedly connected to the second connector 35, and the first connector 34 is connected to the wiping cloth assembly 2.

[0161] In a specific example, please see Figure 18The intermediate transmission structure 33 includes a worm 331, a turbine 332, a first gear 333 and a second gear 334. The worm 331 is connected to the drive motor 32, the turbine 332 meshes with the worm 331, the first gear 333 is coaxially arranged with the turbine 332, and the second gear 334 meshes with the first gear 333.

[0162] Please see Figure 16 The second gear 334 is supported on the housing 31 by bearings 36. One end of the first connecting member 34 is inserted into the second gear 334. The axes of the first connecting member 34 and the second gear 334 are collinear. One of the first connecting member 34 and the second gear 334 has a protrusion, and the other has a groove. The protrusion is located in the groove, and the groove extends along the axial direction of the first connecting member 34. The protrusion can slide along the extension direction of the groove, so that when the second gear 334 rotates, it drives the first connecting member 34 to rotate, and the first connecting member 34 can also move relative to the second gear 334 along the axial direction. The first connecting member 34 has a mounting hole 341. The wiping assembly 2 is inserted into the mounting hole 341 on the first connecting member 34 from the side away from the second gear 334. The wiping assembly 2 is fixedly connected to the first connecting member 34. The first connecting member 34 has a threaded groove 342. The inner side of the cylindrical second connecting member 35 has a threaded protrusion (the threaded protrusion is located in...). Figure 16 (Not shown in the diagram), the threaded protrusion mates with the threaded groove 342, and the threaded protrusion and the threaded groove 342 form a threaded connection.

[0163] See Figure 16 An annular portion 351 is formed on the outer circumferential surface of the second connector 35. The annular portion 351 is added between the first component 38 and the second component 39. A spring 310 is provided below the second component 39. The spring 310 is pressed between the inner side of the housing 31 and the second component 39.

[0164] For information on the cloth limiting component, please refer to [link / reference]. Figure 16 A limiting component 37 is provided on the first connecting member 34. When the drive motor 32 drives the first connecting member 34 to rotate, the second connecting member 35 is limited on the housing 31 by the first component 38 and the second component 39, so the second connecting member 35 does not move, and the first connecting member 34 moves downward. When it moves to the point where the limiting component 37 abuts against the threaded protrusion on the second connecting member 35, the first connecting member 34 drives the second connecting member 35 to rotate. That is, the force of the first connecting member 34 acting on the second connecting member 35 overcomes the force of the first component 38 and the second component 39 on the second connecting member 35. When the first connecting member 34 and the second connecting member 35 rotate together, the first connecting member 34 no longer moves downward. When the drive motor 32 drives the first connecting member 34 to rotate in the opposite direction, the second connecting member 35 does not move, and the first connecting member 34 rotates in the opposite direction and moves upward. When the first connecting member 34 moves to the point where... Figure 16 When the position shown is reached, the threaded protrusion abuts against the end of the threaded groove 342, causing the first connector 34 to rotate in the opposite direction along with the second connector 35, and the first connector 34 no longer moves upward.

[0165] The above provides a specific embodiment of the cloth driving component 3, but the structure of the cloth driving component 3 is not limited to the content of the above specific embodiment.

[0166] In an embodiment where the number of thread turns in the threaded structure 13 is consistent with the number of thread turns between the first connector 34 and the second connector 35, when the first connector 34 rotates in the reverse direction until the threaded protrusion on the second connector 35 abuts against the end of the threaded groove 342, the first connector 34 stops rising and moves the wiping assembly 2 to a high position, while the wiping assembly 2 moves the scraping assembly 12 to a second position. When the second connector 34 rotates in the forward direction until the limiting member 37 abuts against the threaded protrusion on the second connector 35, the first connector 34 stops falling and moves the wiping assembly 2 to a low position, while the wiping assembly 2 moves the scraping assembly 12 to a first position.

[0167] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
