Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more particularly, to a cleaning method and a cleaning device. Background Art

[0002] Cleaning robots include floor-sweeping robots, mopping machines (robots with mopping functions but without sweeping functions), double-rotating floor-sweeping machines, floor washing machines, etc. The cleaning robot can perform wet cleaning on the surface to be cleaned (such as the ground or the tabletop) by contacting the mop with the surface to be cleaned in the mopping mode. During the process of the mop cleaning the surface to be cleaned, the mop can swing between the retracted position and the extended position relative to the main body of the cleaning robot device to reduce the cleaning dead corners on the ground and improve the cleaning effect on the ground.

[0003] During the process of the cleaning device performing wet cleaning on the surface to be cleaned, in order to ensure the humidity of the mop, water needs to be supplied to the mop. Currently, during the process of supplying water to the mop, the movement trajectory of the mop is cumbersome and some areas cannot be cleaned properly, resulting in many cleaning blind spots due to missed mopping, and it is difficult to guarantee the cleaning effect, and the user experience is poor. Summary of the Invention

[0006] Driving a cleaning component located at the bottom of the cleaning device by the cleaning device to travel, so that the cleaning component cleans the surface to be cleaned. The cleaning component has a retracted position, a transition position, and an extended position. When the cleaning component is in the extended position, the part located outside the edge contour of the cleaning device is larger than the part located outside the edge contour of the cleaning device when the cleaning component is in the retracted position. The transition position is between the retracted position and the extended position;

[0007] When the cleaning component is in the retracted position, the transition position, and the extended position, a fluid can be provided to the cleaning component in response to a received first trigger signal to wet the cleaning component.

[0012] Further, the step of providing the fluid to the cleaning component in response to the first trigger signal further includes:

[0013] The cleaning component is controlled to be maintained at the expanded position, so that during the process of the cleaning component performing edge cleaning along the obstacle, the fluid is provided to the cleaning component in response to the first trigger signal.

[0014] Further, the step of providing the fluid to the cleaning component in response to the first trigger signal further includes:

[0015] During the process of the cleaning component located at the expanded position performing edge cleaning along the obstacle and moving in the direction close to the retracted position under the resistance force of the obstacle, the fluid is provided to the cleaning component in response to the first trigger signal.

[0016] Further, during the process of the cleaning component located at the expanded position performing edge cleaning along the obstacle and moving in the direction close to the retracted position under the resistance force of the obstacle, the step of providing the fluid to the cleaning component includes:

[0017] When the cleaning component moves from the expanded position to the state of being maintained at the transition position or the retracted position under the extrusion of the resistance force, the fluid is provided to the cleaning component in response to the first trigger signal.

[0018] Further, the step of providing the fluid to the cleaning component in response to the first trigger signal further includes:

[0019] When the cleaning component is in contact with an obstacle and performs edge cleaning along the obstacle, if the contact force exerted by the obstacle on the cleaning component is withdrawn, then within the time period when the cleaning component returns from the retracted position or the transition position to the expanded position or when it returns to the expanded position, the fluid can be provided to the cleaning component in response to the first trigger signal.

[0020] Further, the step of providing the fluid to the cleaning component in response to the first trigger signal further includes:

[0021] When the cleaning component is in an open area away from the obstacle and the cleaning component is controlled to remain in the retracted position, the fluid is provided to the cleaning component in response to the first trigger signal.

[0022] Further, the first trigger signal includes a signal received when the cleaning component reaches a preset fluid supply condition and / or a trigger signal input by the user; and / or,

[0023] Before the cleaning component moves from one of the retracted position, the transition position, and the expanded position to another one by performing a first motion action, and before the cleaning device drives the cleaning component located at the bottom of the cleaning device to travel to clean the surface to be cleaned, the method further includes:

[0024] A fluid supply component is provided in the cleaning device, and at least one outlet of the fluid supply component is provided on a moving member, so as to, in response to the first trigger signal, open the fluid supply component so that the fluid supply component provides the fluid to the cleaning component through at least one of the outlets, wherein the moving member is a structural member provided in the cleaning device and capable of performing the first motion action along with the cleaning component.

[0025] On the other hand, the present application further provides a cleaning device for performing the cleaning method, and the cleaning device includes:

[0026] A main body;

[0027] A cleaning component provided at the bottom of the main body;

[0028] A fluid supply component provided in the main body;

[0030] During the process of cleaning a surface to be cleaned by driving a cleaning component to move forward through a cleaning device provided in this application, fluid can be provided to the cleaning component in response to a received first trigger signal when the cleaning component is in the retracted position, the transition position, and the expanded position, so as to wet the cleaning component. That is to say, the cleaning method provided in this application can provide fluid to the cleaning component in the retracted position, the expanded position, and the transition position. Even when an obstacle causes the cleaning component to be in the transition position, fluid can still be continuously provided to the cleaning component. During this process, since the cleaning component does not need to return to a specified position to provide fluid, the movement trajectory of the cleaning component can be simplified, and the working process of the cleaning component becomes more natural and smooth. The cleaning component will not miss a cleaning area because it needs to move to a specified position to replenish fluid, and cleaning blind spots can be reduced or even eliminated. At the same time, since fluid does not need to be provided only when the cleaning component is in a specified position, the cleaning device does not need to be equipped with a position detection device to detect when the cleaning component is in the specified position to provide fluid, reducing the position detection process and detection device. The control process for providing fluid is more efficient and direct, with lower costs and energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0049] Currently, when a cleaning device needs to supply water to a mop to wet the mop, it is necessary to switch the mop to the retracted position. If the mop is in the extended position or in a transition position between the extended position and the retracted position before water supply and is performing edge cleaning along an obstacle such as a wall, when it returns to the retracted position for water supply, since it can only return to the transition position or the extended position to continue cleaning after the water supply is completed. During the water supply to the mop, there will be some areas at the outer edge of the obstacle that cannot be cleaned, forming a cleaning blind spot. Obstacles include walls, columns, sofas, cabinets, table legs, chair legs, corners, inner right angles, outer right angles, etc. Moreover, the cleaning device also needs to be equipped with at least two in-place detection devices to detect whether the mop moves to the retracted position or the extended position, resulting in a relatively high cost of the cleaning device. In the scenario of edge cleaning, since the mop needs to return to the extended position or the transition position before water supply after the water supply is completed, the movement trajectory of the mop is relatively cumbersome and the energy consumption is high. For example, if the mop of the cleaning device can be retracted passively, when it encounters an obstacle and is retracted passively from the extended position to the transition position or the retracted position, no water is supplied at this time, and it is necessary to retract the mop to the retracted position and then supply water, resulting in a cumbersome movement trajectory of the extended mop and causing missed cleaning.

[0050] In view of the foregoing problems, the first embodiment of the present invention provides a cleaning method, which is applied to a cleaning device. Please refer to Figure 1 , and the cleaning method includes the following steps:

[0051] Step S11: Drive a cleaning assembly 20 located at the bottom of the cleaning device by the cleaning device to travel, and use the cleaning assembly 20 to clean a surface to be cleaned. The cleaning assembly 20 has a retracted position, a transition position, and an extended position. When the cleaning assembly 20 is in the extended position, the part located outside the edge contour of the cleaning device is larger than the part located outside the edge contour of the cleaning device when the cleaning assembly 20 is in the retracted position. The transition position is located between the retracted position and the extended position.

[0052] Among them, when the cleaning component 20 is in the retracted position, the cleaning component 20 can be entirely located outside the edge contour of the cleaning device body 10, or at least partially located outside the edge contour of the body 10 and at least partially located inside the edge contour of the body 10. In this regard, this embodiment does not make a unique limitation. When the cleaning component 20 is in the expanded position, it can increase the cleaning coverage rate of the corner area between the outer edge of the obstacle and the body 10.

[0053] Step S12: When the cleaning component 20 is in the retracted position, the transition position, and the expanded position, fluid can be provided to the cleaning component 20 in response to the received first trigger signal to wet the cleaning component 20. The fluid in this embodiment can include at least one of water and a mixture of water and a cleaning agent.

[0054] That is to say, during the cleaning process of the cleaning component 20, no matter which position the cleaning component 20 is currently in, as long as fluid needs to be replenished, it can be replenished at any time without having to move from the current position (such as the expanded position) to a designated position (such as the retracted position) for fluid replenishment. This simplifies the movement trajectory generated by the cleaning component 20 during the cleaning operation. Therefore, the cleaning component 20 can replenish fluid at any time during the traveling process, avoiding excessive position-changing movements of the cleaning component 20, preventing jamming and unsmoothness caused by the need for position-changing, and saving energy consumption. Moreover, since fluid can be replenished to the cleaning component 20 at any time, there will be no missed cleaning situation. Especially during the edge cleaning of the cleaning component 20 along an obstacle, since the cleaning component 20 can always remain in the expanded position or remain in the transition position under the abutment of the obstacle to replenish fluid while performing edge cleaning, the generation of cleaning blind spots is avoided, making the cleaning ability and cleaning effect of the cleaning device better and greatly improving the user experience. In addition, since there is no need to return to a designated position for fluid replenishment, the installation of a position detection device can be omitted, enabling the production and use costs of the cleaning device to be lower.

[0055] It can be seen that in the cleaning method provided in this embodiment, during the process of driving the cleaning component 20 to travel by the cleaning device to clean the surface to be cleaned, when the cleaning component 20 is in the retracted position, the transition position, and the expanded position, fluid can be provided to the cleaning component 20 in response to the received first trigger signal to moisten the cleaning component 20. That is to say, the cleaning method provided in this application can provide fluid to the cleaning component 20 in the retracted position, the expanded position, and the transition position. Even when an obstacle causes the cleaning component 20 to be in the transition position, fluid can be continuously provided to the cleaning component 20. During this process, since the cleaning component 20 does not need to return to a specified position to provide fluid, the movement trajectory of the cleaning component 20 can be simplified, and the working process of the cleaning component 20 can be made more natural and smooth. The cleaning component 20 will not miss the cleaning area because it needs to move to a specified position to replenish fluid, and the cleaning blind area of the cleaning device can be reduced or even eliminated. At the same time, since it is not necessary for the cleaning component 20 to provide fluid only at a specified position, the cleaning device does not need to be equipped with a position detection device to provide fluid when it detects that the cleaning component 20 is in the specified position. The process of providing fluid is more efficient and direct, with lower costs and energy consumption.

[0056] The first trigger signal in this embodiment includes the signal received when the cleaning component 20 reaches the preset fluid supply condition and / or the trigger signal input by the user. That is to say, in this embodiment, the fluid supply condition can be set in advance to determine when to replenish fluid to the cleaning component 20, or the trigger signal input by the user can be received when the user deems it necessary to replenish fluid to replenish the cleaning component 20 with fluid. In this regard, as long as it can be ensured that the cleaning component 20 can clean the surface to be cleaned in a relatively moist state, this embodiment does not make a unique limitation on the generation of the first trigger signal.

[0057] Among them, the fluid supply conditions in this embodiment may include that when the distance traveled by the cleaning device after a fluid replenishment on the cleaning component 20 is greater than or equal to the set distance, or when the duration of the cleaning device's travel after the last fluid replenishment on the cleaning component 20 reaches the set duration. Or, if the cleaning device was located at the first position when the fluid supply component 30 was last opened to replenish fluid for the cleaning component 20, during the process of cleaning the outer edge of the object when the cleaning component 20 is in the expanded position, obtain the first travel distance between the current position of the cleaning device and the first position, so as to determine whether to open the fluid supply component 30 to replenish fluid for the cleaning component 20 based on the ratio between the first travel distance and the set distance. For example, if the ratio is less than the set value, the fluid supply component 30 is not opened; if it is not less than the set value, the fluid supply component 30 is opened. Or, during the process of cleaning when the cleaning component 20 is in the expanded position, determine the second travel distance between the current position of the cleaning device and the first position. If the second travel distance is not less than the set upper limit distance, control the cleaning component 20 to switch from the expanded position to the retracted state and open the fluid supply component 30. The main purpose of setting the fluid supply conditions in this embodiment is to replenish fluid for the cleaning component 20, so that the cleaning component 20 can always clean the surface to be cleaned in a relatively moist state. At the same time, it can also ensure that the cleaning component 20 will not cause the area of the surface to be cleaned to be overly moist due to excessive wetness, and it is not easy to leave obvious water stains or water marks on the surface to be cleaned, improving the cleaning effect. Secondly, it can also reduce the damage to the surfaces to be cleaned of different materials (such as swelling, foaming, deformation, etc. of the wooden surface to be cleaned), and even reduce the growth of bacteria and molds, improving air quality.

[0058] In step S12, the step of supplying fluid to the cleaning component 20 in response to the received first trigger signal includes:

[0059] When the cleaning component 20 is in the first cleaning state or the second cleaning state, supply fluid to the cleaning component 20 in response to the first trigger signal. The first cleaning state is a state where the cleaning component 20 remains in one of the retracted position, the transition position, and the expanded position. The second cleaning state is a state where the cleaning component 20 moves from one of the retracted position, the transition position, and the expanded position to another, such as the cleaning component 20 moving from the retracted position to the transition position, directly moving from the retracted position to the expanded position, moving from the transition position to the expanded position, moving from the expanded position to the transition position, directly moving from the expanded position to the retracted position, moving from the transition position to the retracted position, etc.

[0060] Thus, whether the cleaning assembly 20 is in the first cleaning state and remains at the corresponding position to clean the surface to be cleaned, or is in the second cleaning state and switches between different positions to perform cleaning work, as long as the cleaning assembly 20 needs to be replenished with fluid, in this embodiment, fluid can be replenished to the cleaning assembly 20 to ensure that when the cleaning assembly 20 remains at the corresponding position and travels with the cleaning device and when the cleaning assembly 20 switches positions during travel, fluid can be replenished in a timely manner, avoiding the situation where the cleaning effect is reduced due to untimely fluid replenishment resulting in dry cleaning of the cleaning assembly 20.

[0061] In some embodiments, the step of providing fluid to the cleaning assembly 20 in response to a first trigger signal includes:

[0062] During the process of controlling the cleaning assembly 20 to move from one of the retracted position and the extended position to the other, fluid is provided to the cleaning assembly 20 in response to the first trigger signal. In this regard, this scenario mainly exists when the cleaning assembly 20 needs to travel with the cleaning device from an open area away from obstacles to perform edge cleaning along the outer edge of an obstacle. The cleaning assembly 20 expands from the retracted position to the extended position to perform edge cleaning on the area around the obstacle. Thus, before the cleaning assembly 20 moves to the extended position, once the cleaning assembly 20 reaches the timing of fluid replenishment (such as when the user drives fluid replenishment or when the fluid supply condition is met), regardless of whether the cleaning assembly 20 has moved in place or is still in the process of moving, fluid can be replenished to the cleaning assembly 20, avoiding the situation of dry cleaning of the cleaning assembly 20 in some areas, improving the cleaning effect, and not causing the generation of cleaning blind spots.

[0063] In some embodiments, when the cleaning assembly 20 needs to switch from the extended position to the retracted position to replenish fluid, the process of the cleaning assembly 20 moving to the retracted position and the process of replenishing fluid in the retracted position will both result in some areas on the outer edge of the obstacle not being cleaned properly, thus generating more cleaning blind spots. In the method provided in this embodiment, the step of providing fluid to the cleaning assembly 20 in response to the first trigger signal further includes:

[0064] Controlling the cleaning assembly 20 to remain in the extended position so that during the process of the cleaning assembly 20 performing edge cleaning along the obstacle, fluid is provided to the cleaning assembly 20 in response to the first trigger signal. When the cleaning assembly 20 performs edge cleaning on the obstacle, the cleaning assembly 20 can perform edge cleaning along the outer edge of the obstacle, or can perform a cleaning method when the distance between the cleaning assembly 20 and the outer edge of the obstacle is not greater than a predetermined distance value, such as performing edge cleaning when the distance between the cleaning assembly 20 and the outer edge of the obstacle is about 4 mm. The size of the predetermined distance value can be specifically determined according to the actual use environment, and this embodiment does not make a unique limitation.

[0065] Therefore, during the process of the cleaning component 20 performing edge cleaning on an obstacle in the expanded position, since the cleaning component 20 does not need to switch from the expanded position to a designated position (such as the retracted position) for fluid replenishment, this can not only ensure that the cleaning component 20 always remains in a relatively wet state during edge cleaning to improve the cleaning effect of the edge cleaning area, but also avoid the cleaning blind area where cleaning is missed due to the need to switch positions for fluid replenishment. After the fluid replenishment is completed, the cleaning component 20 can continue to perform edge cleaning in the expanded position until it leaves the obstacle. The fluid replenishment process does not require a position switching movement, and the energy consumption generated by the cleaning device is low.

[0066] In this embodiment, the step of supplying fluid to the cleaning component 20 in response to the first trigger signal further includes:

[0067] During the process that the cleaning component 20 is performing edge cleaning along an obstacle in the expanded position and moves in the direction close to the retracted position under the abutting force of the obstacle, fluid is supplied to the cleaning component 20 in response to the first trigger signal. That is to say, when the cleaning component 20 is performing edge cleaning in the expanded position and is abutted by the obstacle, as long as the cleaning component 20 reaches the timing of fluid replenishment, fluid can be supplied to the cleaning component 20 at any time, so as to improve the cleaning effect during the edge cleaning process of the cleaning component 20 and avoid the generation of cleaning blind areas. The fluid replenishment process does not require position switching or reset operations, and the cleaning action looks natural and smooth. There will be no situation where the cleaning component 20 cannot replenish fluid due to being passively retracted by the extrusion of the obstacle, making the timing of fluid replenishment for the cleaning component 20 more flexible and timely.

[0068] Among them, during the process that the cleaning component 20 is performing edge cleaning along an obstacle in the expanded position and moves in the direction close to the retracted position under the abutting force of the obstacle, the step of supplying fluid to the cleaning component 20 includes:

[0069] When the cleaning component 20 moves from the expanded position to a state of remaining in the transition position or the retracted position under the extrusion of the abutting force, fluid is supplied to the cleaning component 20 in response to the first trigger signal.

[0070] Therefore, when the cleaning component 20 is passively moved from the expanded position to the transition position or the retracted position due to the abutting force of the obstacle, as long as the cleaning component 20 needs fluid replenishment, fluid can be supplied to the cleaning component 20 in time in response to the first trigger signal, so that the cleaning component 20 can clean the surface to be cleaned in a relatively wet state in the transition position or the retracted position, improving the cleaning effect when the cleaning component 20 is passively retracted.

[0071] In the method provided by this embodiment, the step of supplying fluid to the cleaning component 20 in response to the first trigger signal further includes:

[0072] During the process that the cleaning component 20 abuts against an obstacle and performs edge cleaning along the obstacle, if the abutting force exerted by the obstacle on the cleaning component 20 is withdrawn, then within the time period when the cleaning component 20 returns from the retracted position or the transition position to the expanded position or when it returns to the expanded position, fluid can be provided to the cleaning component 20 in response to a first trigger signal.

[0073] Thereby, the cleaning component 20 will not cause the situation that the cleaning component 20 cannot be replenished with fluid in time due to returning to a specified position (such as the expanded position or the retracted position), ensuring that the cleaning component 20 always remains in a relatively wet state, and improving the wetness degree and cleaning effect of the cleaning component 20 during the period from passive retraction to returning to the expanded position.

[0074] In the method provided in this embodiment, the step of providing fluid to the cleaning component 20 in response to the first trigger signal further includes:

[0075] When the cleaning component 20 is located in an open area away from the obstacle and the cleaning component 20 is controlled to remain in the retracted position, fluid is provided to the cleaning component 20 in response to the first trigger signal. That is to say, in this embodiment, when the cleaning component 20 does not travel along the obstacle for edge cleaning, as long as the cleaning component 20 reaches the timing of replenishing fluid, fluid can be provided to the cleaning component 20 to ensure the wetness degree and cleaning effect of the cleaning component 20 during the cleaning process in the open area. The open area can specifically be an area whose area size is larger than a predetermined value than the projected outer contour area of the cleaning device in the height direction of itself, so that the cleaning device will not encounter an obstacle during the process of freely traveling in this open area.

[0076] When the cleaning component 20 is cleaning in an open area away from the obstacle, the cleaning device is in a non-edge cleaning state or a free cleaning state. The non-edge cleaning state or the free cleaning state is the state in which the cleaning device performs cleaning work when the distance between the cleaning device and the outer edge of the obstacle is greater than a second preset distance. Here, the second preset distance is greater than the predetermined distance value described above.

[0077] In this embodiment, the cleaning component 20 moves from one of the retracted position, the transition position, and the expanded position to another through a first motion action. The first motion action can be a linear motion or a curved motion, which specifically depends on the driving mechanism that drives the cleaning component 20 to swing, and this embodiment does not make a unique limitation. Before driving the cleaning component 20 located at the bottom of the cleaning device to travel to clean the surface to be cleaned, the method provided in this embodiment further includes the following steps:

[0078] A fluid supply component 30 is provided in the cleaning device, and at least one outlet 301 of the fluid supply component 30 is provided on the moving member 50. In response to the first trigger signal, the fluid supply component 30 is opened so that the fluid supply component 30 supplies fluid to the cleaning component 20 through at least one outlet 301, wherein the moving member 50 is a structural member provided in the cleaning device and capable of making a first movement action along with the cleaning component 20.

[0079] Thus, in this embodiment, the outlet 301 through which the fluid flows to the cleaning component 20 is provided on the moving member 50. Since the moving member 50 can make a first movement action along with the cleaning component 20, that is, the outlet 301 can move along with the cleaning component 20. During the process of the cleaning component 20 making a first movement action and switching positions, the outlet 301 and the cleaning component 20 can move synchronously. Along the height direction of the cleaning device, the outlet 301 remains stationary relative to the cleaning component 20, and the fluid flowing out of the outlet 301 can directly flow onto the cleaning component 20, and is not easily thrown out under the impact of the cleaning component 20 due to dripping to other positions of the cleaning component 20, preventing the liquid from splashing outside the cleaning component 20 and splashing onto objects such as the ground, walls, and furniture, and avoiding obvious water stains on the ground or the walls and furniture being wet and damaged by the liquid.

[0080] As can be seen from the above, in this embodiment, when the cleaning component 20 needs to be supplemented with fluid, no matter which position the cleaning component 20 is in or between which two positions it switches its movement, fluid can be supplied to the cleaning component 20 (by opening the fluid supply component 30 to supply the required fluid to the cleaning component 20), so that the cleaning component 20 can be wetted when it remains in the corresponding position or is in the transition stage from one position to another.

[0081] When the cleaning component 20 walks along an obstacle for edge cleaning, the cleaning component 20 is controlled to be in an expanded position or a transition position, and the cleaning component 20 in edge cleaning is supplemented with fluid according to the received first trigger signal, thereby wetting the flexible cleaning member 22 (i.e., the mop) of the cleaning component 20. Thus, during the edge cleaning process of the cleaning component 20, there is no need to switch to the retracted position for fluid supplementation, and the fluid supplementation does not require a position switching operation, avoiding the generation of cleaning blind spots and making the cleaning effect better.

[0082] When the cleaning component 20 is abutted by an obstacle, causing the cleaning component 20 to be passively adducted under the action of the abutting force of the obstacle, fluid can also be supplied to the cleaning component 20 in the edge cleaning in response to the received first trigger signal, so as to moisten the cleaning component 20, enabling the cleaning component 20 in the abutting state to also be moistened, improving the cleaning effect and avoiding the generation of cleaning blind spots. When the cleaning component 20 is separated from the obstacle, fluid can also be supplied to the cleaning component 20 in the outward expansion position in response to the received first trigger signal, so as to moisten the cleaning component 20, ensuring the cleaning effect and cleaning efficiency during the edge cleaning process of the cleaning component 20 and avoiding the generation of cleaning blind spots. When the cleaning component 20 does not walk along the outer edge of the obstacle for edge cleaning, the cleaning component 20 can be controlled to adduct to the adducted position, and during the normal cleaning process when the cleaning component 20 is in the adducted position, fluid can be supplied to the cleaning component 20 in response to the received first trigger signal, improving the cleaning effect during the normal cleaning of the cleaning component 20.

[0083] The second embodiment of the present invention also provides a cleaning device, which is used to execute the cleaning method. For the cleaning method, please refer to the content provided in the first embodiment of the present invention. Please refer to Figures 2 to 11 , the cleaning device includes a main body 10, a cleaning component 20, a fluid supply component 30, and a controller 40. The cleaning component 20 is provided at the bottom of the main body 10 so that the cleaning component 20 can clean the surface to be cleaned. The fluid supply component 30 is provided on the main body 10, and the fluid stored in the fluid supply component 30 can be supplied to the cleaning component 20 to moisten the cleaning component 20.

[0084] The controller 40 is electrically connected to the fluid supply component 30, and the controller 40 is configured to open the fluid supply component 30 to supply fluid to the cleaning component 20 in response to the received first trigger signal when the cleaning component 20 is in the adducted position, the transition position, and the outward expansion position. The controller 40 may include a single-chip microcomputer, a microcontroller, and a central processing unit. The controller 40 can be integrated on a circuit board and installed inside the main body 10. The controller 40 can be installed between the fixed shell 11 and the bottom shell 12 of the main body 10 to avoid the controller 40 from being interfered with and damaged by the external environment, improving the safety and reliability of the controller 40.

[0085] During the process of the cleaning device provided in this embodiment driving the cleaning assembly 20 to travel for cleaning the surface to be cleaned, when the cleaning assembly 20 is in the retracted position, the transition position, and the expanded position, the controller 40 can respond to the received first trigger signal to open the fluid supply assembly 30 to supply fluid to the cleaning assembly 20 to wet the cleaning assembly 20. That is to say, the cleaning device provided in this application can supply fluid to the cleaning assembly 20 through the fluid supply assembly 30 at the retracted position, the expanded position, and the transition position. Even when an obstacle causes the cleaning assembly 20 to be in the transition position, fluid can still be continuously supplied to the cleaning assembly 20. During this process, since the cleaning assembly 20 does not need to return to a specified position to supply fluid, the movement trajectory of the cleaning assembly 20 can be simplified, and the working process of the cleaning assembly 20 can be made more natural and smooth. The cleaning assembly 20 will not miss the cleaning area because it needs to move to a specified position to replenish fluid, and the cleaning blind area can be reduced or even eliminated. At the same time, since it is not necessary for the cleaning assembly 20 to supply fluid only at a specified position, there is no need for the cleaning device to be equipped with a position detection device to supply fluid when it detects that the cleaning assembly 20 is in the specified position, reducing the installation of the position detection device and making the cost and energy consumption of the cleaning device lower.

[0086] Among them, the cleaning assembly 20 moves from one of the retracted position, the transition position, and the expanded position to another through a first motion action. The fluid supply assembly 30 includes at least one outlet 301. As Figure 3 shown, the cleaning device further includes a moving member 50. The moving member 50 is arranged on the main body 10 and can perform the first motion action along with the cleaning assembly 20. At least one of the moving member 50 and the main body 10 is respectively provided with at least one outlet 301, and the fluid supply assembly 30 supplies fluid to the cleaning assembly 20 through the at least one outlet 301.

[0087] That is to say, in this embodiment, the outlet 301 for the fluid to flow to the cleaning assembly 20 can be arranged on the moving member 50 or the main body 10, or at least one outlet 301 can be arranged on both the moving member 50 and the main body 10. When the controller 40 opens the fluid supply assembly 30, the fluid supply assembly 30 can supply the fluid to the cleaning assembly 20 through the at least one outlet 301 on the moving member 50 and / or the main body 10 to wet the cleaning assembly 20.

[0088] When the outlet 301 is arranged on the moving part 50 in this embodiment, since the moving part 50 can perform a first movement action along with the cleaning component 20, that is, the outlet 301 can move along with the cleaning component 20. During the process of the cleaning component 20 switching positions by performing the first movement action, the outlet 301 and the cleaning component 20 can move synchronously. Along the height direction of the cleaning device, the outlet 301 remains stationary relative to the cleaning component 20, and the fluid flowing out of the outlet 301 can directly flow onto the cleaning component 20, and is not easily thrown out under the collision action of the cleaning component 20 due to dripping to other positions of the cleaning component 20, preventing the liquid from splashing outside the cleaning component 20 and splashing onto objects such as the ground, walls, and furniture, avoiding obvious water marks on the ground, or the walls and furniture being damaged by being soaked in the liquid.

[0089] When at least one outlet 301 in this embodiment is arranged on the main body 10, the cleaning component 20 is provided with a diversion structure 213. When the cleaning component 20 is respectively located at the retracted position, the transition position, and the expanded position, along the height direction of the main body 10, the diversion structure 213 respectively has a retracted vertical projection area, a transition vertical projection area, and an expanded vertical projection area at the bottom of the main body 10. At least part of the outlet 301 is located in the first overlapping area where the retracted vertical projection area, the transition vertical projection area, and the expanded vertical projection area overlap. The first overlapping area is Figure 4 the shaded part where the outlet is located in the figure. Thus, regardless of whether the cleaning component 20 is located at the retracted position, the transition position, or the expanded position, since at least part of the outlet 301 is located in the vertical projection area of the corresponding position at the bottom of the main body 10, it can be ensured that the fluid can flow along the outlet 301 to the cleaning component 20 at any position to moisten the cleaning component 20. Of course, it is better that the whole outlet 301 is located in the vertical projection area of the corresponding position, which can reduce the waste of fluid and ensure the moistening degree of the cleaning component 20.

[0090] In this embodiment, the cleaning component 20 includes a bracket 21 and a flexible cleaning member 22. Along the height direction of the main body 10 (such as Figure 6 the direction indicated by the arrow Y in the figure), the flexible cleaning member 22 is arranged on the surface of the bracket 21 away from the main body 10. The diversion structure 213 is arranged on the bracket 21, such as Figure 3As shown, the diversion structure 213 in this embodiment may include a plurality of first through holes 132. Along the height direction of the main body 10, the plurality of first through holes 132 are arranged on the side of the bracket 21 close to the main body 10 and are arranged circumferentially along the bracket 21. Then, when the cleaning assembly 20 is in the retracted position, the transition position, and the expanded position, it is only necessary to ensure that at least a part of the outlet 301 is located in the vertical projection area of at least one first through hole 132 on the main body 10, so as to ensure that at least a part of the outlet 301 can always be aligned with the first through hole 132. When the fluid includes water, the water can directly fall into at least one first through hole 132 along the outlet 301, and then contact the flexible cleaning member 22 to wet the flexible cleaning member 22. The diversion structure 213 may further include a diversion groove 131. The diversion groove 131 is arranged on the side of the bracket 21 close to the main body 10, and the bottom of the diversion groove 131 may be provided with the first through hole 132. Thus, when the cleaning assembly 20 is in the retracted position, the transition position, and the expanded position, it is only necessary to ensure that at least a part of the outlet 301 is located in the vertical projection area of the diversion groove 131 on the main body 10, so as to ensure that at least a part of the outlet 301 can always be aligned with the diversion groove 131 and direct the fluid to the diversion groove 131, and then flow to the flexible cleaning member 22 through the first through hole 132 at the bottom of the diversion groove 131. When the bracket 21 is connected to the transmission shaft 62 of the driving assembly 60, the diversion groove 131 may be arranged to surround the transmission shaft 62 circumferentially, so as to further ensure that at least a part of the outlet 301 can always be aligned with the diversion groove 131, and the start of the diversion groove 131 is simple and convenient, and can reduce the weight of the bracket 21, thereby reducing the driving difficulty of the driving assembly 60 for the bracket 21.

[0091] The first through hole 132 may not be arranged at the bottom of the diversion groove 131, but at a position on the bracket 21 that is offset from the diversion groove 131. The first through hole 132 and the diversion groove 131 can be connected through a connecting pipe or a channel opened on the bracket 21.

[0092] When at least one outlet 301 is arranged on the moving member 50, the cleaning assembly 20 is provided with a diversion structure 213. Along the height direction of the main body 10, at least a part of the projected outer contour of the outlet 301 is located within the projected outer contour of the diversion structure 213. Thus, during the process of the moving member 50 performing the first movement action along with the cleaning assembly 20, at least a part of the outlet 301 can correspond to the diversion structure 213, so as to ensure that the fluid can flow from the outlet 301 into the diversion structure 213 and then wet the cleaning assembly 20. No matter which position the cleaning assembly 20 is in, the cleaning assembly 20 can be replenished with fluid through the outlet 301.

[0093] Such as Figure 6As shown, the body 10 includes a top shell 11 and a bottom shell 12, and the bottom shell 12 is arranged at the bottom of the top shell 11. Along the height direction of the body 10, the cleaning assembly 20 is located at the bottom of the bottom shell 12, and the bottom shell 12 is penetrated by a first avoidance hole 121, the moving part 50 includes a sealing plate 51, and the cleaning device also includes a driving assembly 60.

[0094] The driving assembly 60 includes a driving component 61 and a transmission shaft 62. Along the height direction of the body 10, the driving component 61 is disposed on a side of the bottom shell 12 away from the cleaning component 20 and can perform a first motion relative to the bottom shell 12 along with the cleaning component 20. The transmission shaft 62 is connected to the driving component 61 and can be driven by the driving component 61 to move in a first clockwise direction (such as Figure 6 The first clockwise direction is clockwise or counterclockwise.

[0095] The sealing plate 51 is arranged between the cleaning component 20 and the driving component 61 and covers the first avoidance hole 121. The end of the transmission shaft 62 away from the driving component 61 passes through the first avoidance hole 121 and the sealing plate 51 and is connected to the cleaning component 20, so that the transmission shaft 62 can drive the cleaning component 20 to rotate and clean along the first clockwise direction. At least one outlet 301 is located at the position of the sealing plate 51 relative to the first avoidance hole 121. The driving component 61 can be electrically connected to the controller 40 to control the driving component 61 to start driving the cleaning component 20 to rotate through the controller 40. The driving component 61 can also be electrically connected to another control circuit. The driving component 61 can specifically include a housing, a gear transmission system and a motor, the gear transmission system is installed in the installation space in the housing, the motor is installed on the housing, and the gear transmission system is transmission-connected between the rotating shaft of the motor and the transmission shaft 62.

[0096] like Figures 6 to 9 As shown, when the moving part 50 in this embodiment includes a sealing plate 51, when the sealing plate 51 performs the first movement action with the cleaning component 20, the sealing plate 51 can dynamically seal the space between the inner circumference of the first avoidance hole 121 and the transmission shaft 62 to prevent the liquid from passing through the first avoidance hole 121 and splashing into the inside of the body 10, thereby avoiding the driving component 61 and other electronic devices inside the body 10 from short-circuiting or even burning due to contact with the liquid, thereby extending the service life of the cleaning device. The sealing plate 51 can be specifically fixedly connected to the driving component 61 and / or rotatably connected to the bottom shell 12, so that the sealing plate 51 can move with the movement of the driving component 61 and the cleaning component 20, and the dynamic setting of the outlet 301 can be realized without adding additional components, ensuring that the outlet 301 can always be aligned with the guide structure 213, making the overall structure of the cleaning device more compact and reliable.

[0097] Specifically, when the diversion structure 213 includes at least one first through hole 132, the cleaning assembly 20 includes a bracket 21 and a flexible cleaning member 22. The bracket 21 is connected to the transmission shaft 62. Along the height direction of the main body 10, at least one first through hole 132 is disposed through the bracket 21. The flexible cleaning member 22 is disposed on the surface of the bracket 21 away from the main body 10. Wherein, when the cleaning assembly 20 is in the retracted position, along the height direction of the main body 10, the first through hole 132 has a first projected outer contour on the sealing plate 51. When the cleaning assembly 20 is in the expanded position, along the height direction of the main body 10, the first through hole 132 has a second projected outer contour on the sealing plate 51. The first projected outer contour and the second projected outer contour have a second overlapping area (such as Figure 5 the shaded part in

[0098] ), and the outlet 301 is located within the second overlapping area.

[0099] Thus, when the cleaning assembly 20 is in any one of the retracted position, the transition position, and the expanded position, or during the process of moving from one position to another (such as during the movement between the retracted position and the expanded position), the fluid can accurately enter the first through hole 132 along the outlet 301 and flow to the flexible cleaning member 22. While being able to replenish the cleaning assembly 20 with liquid at any time, the liquid will not flow to the rigid structure positions on the bracket 21 (such as the area between two adjacent first through holes 132, the area between the first through hole 132 and the outer edge of the bracket 21, etc.) and splash to the ground, which can effectively prevent the ground that has been cleaned by the cleaning device from being contaminated by the liquid and achieve an ideal cleaning effect, and the user experience is better.

[0099] In this embodiment, during the process of the cleaning assembly 20 performing the first movement action, when the cleaning assembly 20 also performs a first rotational movement in the first clockwise direction, to ensure that the outlet 301 can always be located within the second overlapping area, the diversion structure 213 (such as the first through hole 132) has a length L1 in the first clockwise direction. When the cleaning assembly 20 moves from the retracted position to the expanded position or from the expanded position to the retracted position, along the first clockwise direction, the arc distance generated by the diversion structure 213 following the first rotational movement of the cleaning assembly 20 is L2, as Figure 5 shown, L1 is greater than L2. It can be understood that the length L1 of the diversion structure 213 in the first clockwise direction is the length of the first through hole 132.

[0100] Thus, during the process of the cleaning assembly 20 performing the first movement action and also performing the first rotational movement, since L1 is greater than L2, after the outlet 301 moves to the retracted or expanded position along with the sealing plate 51, the outlet 301 can always be located within the second overlapping area, thereby effectively preventing the liquid from splashing to the ground during the process of the cleaning assembly 20 performing the first movement action.

[0101] When the fluid includes a liquid (such as clean water or a mixture of clean water and a cleaning agent), and when the cleaning component 20 in this embodiment includes a bracket 21 and a flexible cleaning member 22, the moving member 50 may further include the bracket 21, and at least one outlet 301 is provided on the bracket 21. Thus, during the first movement action of the cleaning component 20, at least one outlet 301 on the bracket 21 will move along with the movement of the cleaning component 20. Therefore, the position of the outlet 301 that supplies liquid to the flexible cleaning member 22 remains unchanged relative to the flexible cleaning member 22, and the liquid flowing out of the outlet 301 can directly flow onto the flexible cleaning member 22 without dripping to other positions of the cleaning component 20, avoiding liquid splashing onto the ground, walls, furniture, etc., and ensuring the water content of the flexible cleaning member 22, reducing the waste of liquid resources.

[0102] Specifically, the outlet 301 on the bracket 21 may be at least one of a nozzle, a spray head, a water pipe joint, etc. provided on the bracket 21 that can be aligned with the flexible cleaning member, and the nozzle is directly connected to the fluid supply component 30. The outlet 301 may also include a through-hole structure penetrating through the bracket 21. Thus, the liquid from the fluid supply component 30 can directly flow along the through-hole structure onto the flexible cleaning member 22 to fully soak the flexible cleaning member 22. Moreover, the outlet 301 of the through-hole structure is convenient to process and can reduce the overall weight of the bracket 21, avoiding situations such as overload of the power source (such as the driving component 60 mentioned in this article) that drives the bracket 21 or a large failure rate due to fatigue work.

[0103] Among them, when the outlet 301 on the bracket 21 is a through-hole structure, in this embodiment, another outlet 301 may be provided on the sealing plate 51 as mentioned above to correspond to the through-hole structure, so as to realize the flow of the liquid provided by the fluid supply component 30 through the outlet 301 on the sealing plate 51 to the through-hole structure on the bracket 21. This can save the operation of setting a rotating connection between the through-hole structure and the fluid supply component 30 and avoid increasing the complexity of the structure of the cleaning component 20.

[0104] In some embodiments, such as Figure 8 and Figure 9 shown, the cleaning device further includes a driving component 60, and the driving component 60 includes a driving part 61 and a transmission shaft 62. Along the height direction of the main body 10, the driving part 61 is provided on the main body 10 and can move relative to the main body 10 along with the cleaning component 20 to perform the first movement action. The transmission shaft 62 is connected to the driving part 61 and can rotate in the first clockwise direction under the drive of the driving part 61. One end of the transmission shaft 62 away from the driving part 61 is connected to the cleaning component 20 and can perform the first movement action. The moving member 50 may further include the transmission shaft 62, and at least one outlet 301 is provided on the transmission shaft 62.

[0105] Accordingly, in this embodiment, at least one outlet 301 of the fluid supply assembly 30 may also be provided on the drive shaft 62, and the fluid supply assembly 30 causes the fluid to flow along the at least one outlet 301 onto the cleaning assembly 20. During the process of the cleaning assembly 20 performing the first motion action, since the drive shaft 62 can perform the first motion action along with the cleaning assembly 20, the outlet 301 will also move along with the movement of the drive shaft 62 and the cleaning assembly 20. Therefore, the position of the outlet 301 relative to the cleaning assembly 20 always remains unchanged, and the fluid flowing out of the outlet 301 can directly flow onto the cleaning assembly 20 without flowing to places other than the cleaning assembly 20. Especially when the fluid includes liquid, it can avoid the liquid splashing onto the ground, walls, furniture, etc., further improving the cleaning effect and user experience when replenishing the cleaning assembly 20 with fluid at any time.

[0106] As Figure 8 shown, the drive shaft 62 in this embodiment may include a first shaft section 621 and a second shaft section 622. The first shaft section 621 is in transmission connection with the driving component 61 and can rotate around its own axis under the drive of the driving component 61. The second shaft section 622 is connected to one end of the first shaft section 621 away from the driving component 61. Among them, to ensure that the fluid of the fluid supply assembly 30 can flow into the outlet 301 on the drive shaft 62 and reduce the complexity of the connecting pipeline. The second shaft section 622 may include a rotary connector 221 and a shaft body 222, and the rotary connector 221 is a cylindrical structure. As Figure 8 and Figure 9 shown, a first inlet 231 is provided on the rotary connector 221, and the first inlet 231 is in communication with the fluid supply assembly 30, and specifically may be in communication with the heater 313 or the water pump 312 of the fluid supply assembly 30 through a hose. Along the axial direction of the first shaft section 621, a second through hole 232 is provided through the rotary connector 221, and the second through hole 232 is sleeved on the outer periphery of the shaft body 222 and forms an installation groove 241 with the shaft body 222 (as Figure 9 shown). And the rotary connector 221 can rotate relative to the shaft body 222 around the axis of the shaft body 222. At least one outlet 301 is provided on the shaft body 222, and the installation groove 241 is in communication between the first inlet 231 and the at least one outlet 301.

[0107] The rotary connector 221 has a first state of moving relative to the main body 10 and a second state of being stationary relative to the main body 10. When the rotary connector 221 is in the first state, it can perform a first movement action along with the cleaning assembly 20. When the cleaning assembly 20 is held in the retracted position, or the transition position, or the expanded position, the rotary connector 221 is held in the second state, and the shaft body 222 can rotate relative to the rotary connector 221 under the drive of the drive member 61. Thus, after the fluid enters the first inlet 231, it flows into at least one outlet 301 on the shaft body 222 along the mounting groove 241. By connecting the outlet 301 to the diversion structure 213 on the bracket 21 of the cleaning assembly 20, during the process of the drive shaft 62 driving the cleaning assembly 20 to perform a first rotational movement for cleaning, the fluid can dynamically flow into the outlet 301 and then flow through the outlet 301 to the diversion structure 213, realizing the wetting of the cleaning assembly 20. In this structure, since the rotary connection between the rotary connector 221 and the shaft body 222 realizes the dynamic transmission of the fluid, the overall structure is compact and reliable. Secondly, to improve the sealing performance during the dynamic transmission of the fluid, as Figure 8 shown, along the axial direction of the shaft body 222, a sealing member 623 can be respectively arranged on the opposite sides of the mounting groove 241. Then, the sealing member 623 and the inner wall surface of the mounting groove 241 enclose a sealed diversion space. At this time, the fluid can be safely and reliably diverted to the cleaning assembly 20 without fluid leakage. The sealing member 623 can include at least one of a flexible rubber ring, a silica gel ring, a fluororubber ring, etc.

[0108] As Figure 8 and Figure 9 shown, a stop structure 70 can be arranged between the rotary connector 221 and the main body 10 to keep the rotary connector 221 in the second state. For example, when the drive shaft 62 needs to pass through the sealing plate 51 to be connected to the cleaning assembly 20, the stop structure 70 can be arranged between the sealing plate 51 and the rotary connector 221. The stop structure 70 can include a stop groove 71, a second avoidance hole 72, and a stop protrusion 73. The second avoidance hole 72 is axially penetrated through the sealing plate 51 along the drive shaft 62, so that the shaft body 222 of the drive shaft 62 can pass through the second avoidance hole 72 to be connected to the cleaning assembly 20. Along the radial direction of the drive shaft 62, the stop groove 71 is recessed on the inner wall surface of the second avoidance hole 72. The stop protrusion 73 is arranged on the side of the rotary connector 221 close to the stop groove 71 and at least partially located in the stop groove 71. The stop protrusion 73 and the rotary connector 221 can be integrally formed or welded to the rotary connector 221. When the drive shaft 62 performs a first movement action along with the cleaning assembly 20, the sealing plate 51 and the rotary connector 221 synchronously perform the first movement action along with the drive shaft 62. At this time, the rotary connector 221 moves relative to the main body 10 (i.e., in the first state).

[0109] When the drive shaft 62 moves with the cleaning assembly 20 to be held in the retracted position, or the transition position, or the expanded position, the stop groove 71 and the stop projection 73 are in circumferential abutment along the drive shaft 62. At this time, the rotary connector 221 is relatively stationary with respect to the main body 10 and held in the second state, while the shaft body 222 rotates relative to the rotary connector 221 under the drive of the drive member 61, so that the fluid can enter the installation groove 241 from the first inlet 231 and be dynamically transmitted to the outlet 301, and then flow from the outlet 301 to the cleaning assembly 20. The overall structure is compact and reliable, with high integration and low complexity, and is convenient to assemble.

[0110] As Figure 8 shown, a socket pipe 731 can be provided on the side of the stop projection 73 close to the top shell 11. The first inlet 231 is provided in the socket pipe 731, and a diversion channel 732 communicating the first inlet 231 and the installation groove 241 is provided in the stop projection 73. Thus, it is only necessary to connect the socket pipe 731 and the heater 313 or the water pump 312 through a pipe to enable the fluid to enter the outlet 301 along the first inlet 231, the diversion channel 732, and the installation groove 241, and then flow from the outlet 301 to the cleaning assembly 20, and the assembly is efficient and convenient. Figure 6 The arrow in

[0111] When the outlet 301 is provided on the drive shaft 62, the bracket 21 can include two parts, a top cover 211 and a chassis 212. The diversion structure 213 further includes a diversion cavity. The top cover 211 and the chassis 212 enclose to form a diversion cavity communicating with the outlet 301, and a first through hole 132 can be provided at the bottom of the diversion cavity. After the fluid enters the diversion cavity from the outlet 301, it directly flows to the flexible cleaning member 22 from the first through hole 132, further ensuring the transmission sealing performance of the fluid and avoiding the problem of fluid leakage. Among them, a groove can be provided on at least one of the chassis 212 and the top cover 211 on the side close to at least the other of them, so as to enclose a diversion cavity after the chassis 212 and the top cover 211 are buckled together, and the assembly is convenient and efficient. The chassis 212 can include a main body portion and a flexible outer ring portion. The flexible outer ring portion is provided on the outer periphery of the main body portion, and the flexible outer ring portion is used to relieve the impact force of the bracket 21 on the obstacle, and avoid the bracket 21 and / or the obstacle (such as furniture, wall) from being damaged. The diversion structure 213 can be provided on both the main body portion and the flexible outer ring portion.

[0112] In some embodiments, the main body 10 includes a top shell 11 and a bottom shell 12. The bottom shell 12 is provided at the bottom of the top shell 11 and encloses an installation space with the top shell 11, and at least one outlet 301 is provided on the bottom shell 12. Combining Figure 3 and Figure 10It can be seen that the fluid supply component 30 includes a fluid supply part 31 and a connection component 32. The fluid supply part 31 is arranged in the installation space and is electrically connected to the controller 40. The connection component 32 includes a water inlet 321 and a cover plate 322. The cover plate 322 is buckled on one side of the bottom shell 12 close to the top shell 11 and encloses a water supply channel 220 with the bottom shell 12. The water inlet 321 is arranged on the cover plate 322 and is communicated with the fluid supply part 31 and the water supply channel 220. When the fluid supply part 31 includes a heater 313, the water inlet 321 can be communicated with the heater 313. Along the height direction of the main body 10, at least one outlet 301 is located at the bottom of the water supply channel 220 and is communicated with the water supply channel 220. After the controller 40 turns on the fluid supply part 31, the fluid flows into at least one outlet 301 through the connection component 32, and then reaches the cleaning component 20. In this embodiment, the outlet 301 is arranged at the bottom of the water supply channel 220, which is convenient and simple to process. And since the water supply channel 220 is formed by the cover plate 322 buckled on the bottom shell 12 and the bottom shell 12, the assembly is convenient and the cost is low.

[0113] In some embodiments, when at least one outlet 301 is arranged on the main body 10, the fluid supply component 30 includes a fluid supply part 31 and a connection component 32. The fluid supply part 31 is arranged on the main body 10 and is electrically connected to the controller 40. As Figure 11 shown, the connection component 32 includes a connection piece 323 and a connecting pipe 324. The connection piece 323 is arranged on the main body 10 and is communicated with at least one outlet 301. One end of the connecting pipe 324 is communicated with the fluid supply part 31, and the other end is communicated with the connection piece 323. After the controller 40 turns on the fluid supply part 31, the fluid flows into the connection piece 323 through the connecting pipe 324, and then is diverted to the outlet 301 through the connection piece 323. The connecting pipe 324 can be a hose or a rigid pipe structure, and the connection piece 323 can be a two-way joint or a three-way joint, etc. The connection component 32 with this structure is convenient to assemble and has a low cost.

[0114] As Figure 6As shown in the figure, the fluid supply component 31 in this embodiment may include a water tank 311, a water pump 312, and a heater 313. The water pump 312 is connected between the water tank 311 and the heater 313 and is electrically connected to the controller 40, so that the controller 40 can control the opening and closing of the water pump 312 to make the water in the water tank 311 flow to the outlet 301. The heater 313 is connected to the connection component 32. The heater 313 may be electrically connected to the controller 40, so that the controller 40 can also control the heater 313 to heat the water from the water tank 311 into warm water or hot water. When the fluid includes at least one of warm water and hot water, in addition to being able to infiltrate the cleaning component 20, it can also improve the dissolving ability of the cleaning component 20 for stubborn stains (such as grease), so as to better clean the stubborn stains. Secondly, because the temperature of the hot water is relatively high, it can also effectively kill the bacteria and mites on the cleaning component 20, achieving the purpose of disinfection and sterilization.

[0115] At least one outlet 301 is correspondingly arranged with at least two groups of cleaning components 20 to supply water to at least two groups of cleaning components 20 through at least one outlet 301 at the same time. It is also possible to arrange at least two outlets 301 in one-to-one correspondence with at least two groups of cleaning components 20, that is, each group of cleaning components 20 corresponds to at least one outlet 301 respectively. In addition, it is also possible to arrange at least one group of cleaning components 20 in correspondence with at least two outlets 301, that is to say, one cleaning component 20 can be supplied with water through at least two outlets 301 at the same time, further improving the wetting efficiency of the cleaning component 20.

[0116] In some embodiments, when the cleaning component 20 has an inward retracted position, a transition position, and an outward expanded position, the cleaning device further includes a driving component 60 and a stop component 80. The driving component 60 is connected to the cleaning component 20 to drive the cleaning component 20 to rotate. As Figure 12 shown, the stop component 80 is arranged on the driving component 60. The stop component 80 is configured to drive the cleaning component 20 to move in the direction close to the inward retracted position when the stop component 80 receives the reaction force (or abutting force) exerted by the obstacle during the process of the cleaning component 20 performing edge cleaning in the outward expanded position. Obstacles are areas such as walls, internal wall corners, external wall corners, furniture corners, etc. For example, when the cleaning device drives the cleaning component 20 to travel from one side of an internal wall corner (such as a wall corner greater than sixty degrees) to the other side, if the stop component 80 receives the reaction force exerted by the wall surface where the other side of the internal wall corner is located, the stop component 80 will drive the cleaning component 20 to move from the outward expanded position to the inward retracted position under the action of the reaction force. When the reaction force is cancelled, the cleaning component 20 can return to the outward expanded position to continue edge cleaning.

[0117] In this embodiment, by providing a stop member 80, when the cleaning assembly 20 expands outward to protrude beyond the outermost edge of the main body 10 in a predetermined direction to clean the edges of obstacles such as walls and furniture, if the cleaning assembly 20 is relatively close to the obstacle, the stop member 80 can contact the obstacle, thereby avoiding hard contact between the cleaning assembly 20 and the obstacle and preventing the obstacle from being scratched. At the same time, the stop member 80 is subjected to the force exerted by the obstacle, which can cause the entire drive assembly 60 to swing, so that the drive assembly can drive the cleaning assembly 20 to move in the direction of the inner retracted position to achieve retraction. It can be seen that the cleaning device in this embodiment is not only convenient for edge cleaning of obstacles, but also not easy to scratch the obstacles.

[0118] When the drive assembly 60 includes a drive member 61 and a transmission shaft 62, along the axial direction of the transmission shaft 62, at least a part of the housing of the drive member 61 extends to a position close to the cleaning assembly 20 of the transmission shaft 62, then the stop member 80 can be connected to the side of the housing of the drive member 61 close to the cleaning assembly 20.

[0119] When the cleaning assembly 20 includes a bracket 21 and a flexible cleaning member 22, the stop member 80 includes a stop plate 81. Within the projection in the height direction of the main body 10, at least a part of the stop plate 81 protrudes beyond the outer edge of the bracket 21. In this way, when the cleaning assembly 20 expands to the expanded position, the stop plate 81 can contact the obstacle prior to the rigid bracket 21 on the cleaning assembly 20, preventing the rigid bracket 21 from scratching the obstacle during the process of rotating to perform the cleaning operation.

[0120] For ease of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the figure. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations are made for the spatial relative descriptions used here.

[0121] In addition, it should be noted that using words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without further statement, the above words have no special meaning, so it cannot be understood as a limitation on the protection scope of this application.

[0122] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
