Description

Technical Field

[0001] This application relates to the field of cleaning technology, and more specifically, to a cleaning device. Background Technology

[0002] Cleaning robots include robotic vacuum cleaners, floor mops (robots with mopping functions but no sweeping function), dual-disc robotic vacuum cleaners, and floor scrubbers. In mopping mode, cleaning robots wet-clean surfaces (such as floors and tabletops) by contacting the mop with the surface to be cleaned. During the cleaning process, the mop can swing between inward and outward positions relative to the robot body to reduce cleaning dead spots and improve cleaning effectiveness.

[0003] During the wet cleaning process of cleaning equipment, water needs to be supplied to the mop to ensure its moisture level. Currently, the mop's movement trajectory is cumbersome and some areas are not cleaned thoroughly, resulting in many cleaning blind spots due to missed areas. This makes it difficult to guarantee the cleaning effect and leads to a poor user experience. Utility Model Content

[0004] The main objective of this application is to provide a cleaning device to solve the problems mentioned in the background art, such as the cumbersome movement trajectory of the mop and the inadequate cleaning of some areas during the process of supplying water to the mop.

Along the height direction of the body, at least one outlet is located at the bottom of the water supply channel and communicates with the water supply channel.

[0026] Furthermore, when at least one of the outlets is provided in the body, the fluid supply component includes:

[0027] A fluid supply component, wherein the fluid supply component is disposed on the body and electrically connected to the controller;

In other words, the cleaning device provided in this application can provide fluid to the cleaning component through the fluid supply component in the retracted position, outward expansion position, and transition position, and can continue to provide fluid even when the cleaning component is in the transition position due to an obstacle. During this process, since the cleaning component does not need to return to a designated position to provide fluid, the movement trajectory of the cleaning component is simplified, and the working process of the cleaning component is more natural and smooth. The cleaning component will not miss cleaning areas due to the need to move to a designated position to replenish fluid, thus reducing or even eliminating cleaning blind spots. At the same time, since the cleaning component does not need to be in a designated position to provide fluid, the cleaning device does not need to have a position detection device to detect when the cleaning component is in a designated position to provide fluid, reducing the installation of position detection devices and lowering the cost and energy consumption of the cleaning device.

Detailed Implementation

[0051] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

[0054] Currently, cleaning equipment requires the mop to be switched to an inward-retracted position when water is supplied to the mop for wetting. If the mop was in an outward-expanded position or a transitional position between the outward and inward positions before water supply, cleaning along obstacles such as walls, pillars, sofas, cabinets, table legs, chair legs, corners, and right angles (both inside and outside) will remain uncleaned during water supply, creating blind spots. Furthermore, the cleaning equipment needs at least two position detection devices to check if the mop has moved to the inward or outward position, increasing the equipment cost. In edge cleaning scenarios, the need for the mop to return to its pre-water supply position (outward or transitional) after water supply results in a cumbersome movement trajectory and higher energy consumption. For example, if the mop of the cleaning equipment can be passively retracted, when it encounters an obstacle and is passively retracted from the outward position to the transition position or the retracted position, water is not supplied at this time. Water needs to be supplied only after the mop is retracted to the retracted position, which makes the movement trajectory of the outward-expanding mop cumbersome and causes missed mopping.

[0055] To address the aforementioned problems, the first embodiment of this utility model provides a cleaning method, which is applied to cleaning equipment. Please refer to [link to relevant documentation]. Figure 1 The cleaning method includes the following steps:

[0056] Step S11: The cleaning component 20 located at the bottom of the cleaning device is moved forward by the cleaning device to clean the surface to be cleaned. The cleaning component 20 has an inward position, a transition position and an outward position. When the cleaning component 20 is in the outward position, the part outside the edge contour of the cleaning device is larger than the part outside the edge contour of the cleaning device when the cleaning component 20 is in the inward position. The transition position is located between the inward position and the outward position.

[0057] When the cleaning component 20 is in the retracted position, it can be entirely located outside the edge contour of the cleaning device body 10, or at least partially located outside and at least partially located inside the edge contour of the body 10. This embodiment does not limit this to a single specific location. When the cleaning component 20 is in the outward-expanded position, it can increase the cleaning coverage of the corner area between the outer edge of the obstacle and the body 10.

[0058] Step S12: When the cleaning component 20 is in the retracted position, the transition position, or the outward expansion position, fluid can be supplied to the cleaning component 20 in response to the received first trigger signal to wet the cleaning component 20. The fluid in this embodiment may include at least one of water, a mixture of water and cleaning agent.

[0059] In other words, during the cleaning process, the cleaning component 20 can replenish fluid whenever needed, regardless of its current position, without requiring it to move from its current location (e.g., an outward-expanding position) to a designated location (e.g., an inward-retracting position) for fluid replenishment. This simplifies the movement trajectory of the cleaning component 20 during cleaning. Therefore, the cleaning component 20 can replenish fluid at any time during its movement, avoiding excessive repositioning and preventing jamming or disruption, while also saving energy. Furthermore, since fluid can be replenished at any time, no cleaning is missed. Especially when the cleaning component 20 is cleaning along obstacles, it can maintain its outward-expanding position or, when encountering an obstacle, its transition position while replenishing fluid and cleaning along the edge, avoiding blind spots and improving the cleaning ability and effect, significantly enhancing 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 eliminated, reducing the production and operating costs of the cleaning equipment.

[0060] As can be seen, in the cleaning method provided in this embodiment, during the process of cleaning the surface to be cleaned by moving the cleaning component 20 with the cleaning equipment, fluid is supplied to the cleaning component 20 in response to the received first trigger signal when the cleaning component 20 is in the retracted position, transition position, and outward expansion position, so as to wet the cleaning component 20. That is to say, the cleaning method provided in this application can supply fluid to the cleaning component 20 in the retracted position, outward expansion position, and transition position, and can continue to supply fluid to the cleaning component 20 even when it encounters an obstacle and is in the transition position. In this process, since the cleaning component 20 does not need to return to a designated position to supply 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 cleaning areas because it needs to move to a designated position to replenish fluid, which can reduce or even eliminate the cleaning blind spots of the cleaning equipment. At the same time, since the cleaning component 20 does not need to be in a designated position to provide fluid, the cleaning equipment does not need to have a position detection device to detect when the cleaning component 20 is in a designated position to provide fluid. This reduces the position detection process and the detection device, making the fluid supply control process more efficient and direct, and reducing costs and energy consumption.

[0061] In this embodiment, the first trigger signal includes a signal received when the cleaning component 20 reaches a preset fluid supply condition and / or a trigger signal input by the user. That is, this embodiment can determine when to replenish fluid to the cleaning component 20 based on preset fluid supply conditions, or it can replenish fluid to the cleaning component 20 by receiving a trigger signal input by the user when the user deems it necessary. Therefore, as long as it ensures that the cleaning component 20 can clean the surface to be cleaned in a relatively moist state, this embodiment does not limit the generation of the first trigger signal to a single specific condition.

[0062] In this embodiment, the fluid supply conditions may include: the distance traveled by the cleaning device after the last fluid replenishment of the cleaning component 20 is greater than or equal to a set distance; or, the duration of travel by the cleaning component 20 after the last fluid replenishment reaches a set duration. Alternatively, if the cleaning device was in a first position when the fluid supply component 30 was last opened to replenish fluid to the cleaning component 20, during the cleaning process of the cleaning component 20 in the outward position cleaning the outer edge of the object, the first travel distance between the current position of the cleaning device and the first position is obtained, and the ratio between the first travel distance and the set distance is used to determine whether the fluid supply component 30 needs to be opened to replenish fluid to the cleaning component 20. For example, if the ratio is less than a set value, the fluid supply component 30 is not opened; if it is not less than a set value, the fluid supply component 30 is opened. Alternatively, during the cleaning process of the cleaning component 20 in the outward position, a second travel distance between the current position of the cleaning device and the first position is determined. If the second travel distance is not less than a set upper limit distance, the cleaning component 20 is controlled to switch from the outward position to the inward position, and the fluid supply component 30 is opened. The main purpose of setting the fluid supply conditions in this embodiment is to replenish the cleaning component 20 with fluid, so that the cleaning component 20 can always clean the surface to be cleaned in a relatively moist state, while also ensuring that the cleaning component 20 is not too wet, causing the cleaned area to become excessively wet, thus preventing obvious water stains or marks from being left on the surface and improving the cleaning effect. Secondly, it can also reduce damage to the surface to be cleaned of different materials (such as swelling, foaming, and deformation of wooden surfaces), and even reduce the growth of bacteria and mold, thereby improving air quality.

[0063] In step S12, the step of providing fluid to the cleaning assembly 20 in response to the received first trigger signal includes:

[0064] When the cleaning component 20 is in a first cleaning state or a second cleaning state, fluid is supplied to the cleaning component 20 in response to a first trigger signal. The first cleaning state is when the cleaning component 20 is held in one of three positions: an inward position, a transition position, or an outward position. The second cleaning state is when the cleaning component 20 moves from one of the three positions to another, such as moving from the inward position to the transition position, moving directly from the inward position to the outward position, moving from the transition position to the outward position, moving from the outward position to the transition position, moving directly from the outward position to the inward position, or moving from the transition position to the inward position.

[0065] Therefore, regardless of whether the cleaning component 20 is in the first cleaning state and maintaining its position to clean the surface to be cleaned, or in the second cleaning state and switching between different positions to perform cleaning work, as long as the cleaning component 20 needs to be replenished with fluid, this embodiment can replenish the cleaning component 20 with fluid. This ensures that the cleaning component 20 can be replenished with fluid in a timely manner when it is in the corresponding position and when it switches positions during the movement of the cleaning equipment, thus avoiding the situation where the cleaning component 20 is dry due to untimely fluid replenishment, which would reduce the cleaning effect.

[0066] In some embodiments, the step of providing fluid to the cleaning assembly 20 in response to a first trigger signal includes:

[0067] During the process of controlling the cleaning component 20 to move from one of the retracted position and the expanded position to the other, fluid is supplied to the cleaning component 20 in response to a first trigger signal. This scenario primarily occurs when the cleaning component 20 needs to move from an open area away from an obstacle to a location requiring edge cleaning along the outer edge of an obstacle. The cleaning component 20 expands from the retracted position to the expanded position to perform edge cleaning around the obstacle. Therefore, before the cleaning component 20 moves to the expanded position, once the fluid replenishment opportunity is reached (e.g., user-driven fluid replenishment, or fluid replenishment when conditions are met), fluid can be supplied to the cleaning component 20 regardless of whether it has reached its position or is still in motion. This prevents the cleaning component 20 from causing dry cleaning in certain areas, improving cleaning effectiveness while avoiding the creation of cleaning blind spots.

[0068] In some embodiments, when the cleaning component 20 needs to switch from an expanded position to an inward position to replenish fluid, the process of the cleaning component 20 moving to the inward position and the process of replenishing fluid in the inward position will result in some areas of the outer edge of the obstacle not being cleaned properly, thus creating more cleaning blind spots. To address this, the method provided in this embodiment further includes the step of providing fluid to the cleaning component 20 in response to the first trigger signal:

[0069] The cleaning component 20 is kept in the extended position so that, during the edge cleaning process along the obstacle, fluid is supplied to the cleaning component 20 in response to a first trigger signal. When cleaning the obstacle along its edge, the cleaning component 20 can clean along the outer edge of the obstacle, or it can clean when the distance between the cleaning component 20 and the outer edge of the obstacle is no greater than a predetermined distance value, such as when the distance between the cleaning component 20 and the outer edge of the obstacle is approximately 4 mm. The predetermined distance value can be determined according to the actual usage environment; this embodiment does not impose a unique limitation.

[0070] Therefore, in this embodiment, when the cleaning component 20 is in the outward position and is cleaning the obstacle along the edge, since the cleaning component 20 does not need to switch from the outward position to a designated position (such as the inward position) to replenish the fluid, this not only ensures that the cleaning component 20 is always kept in a relatively moist state during the edge cleaning process to improve the cleaning effect of the edge cleaning area, but also avoids the creation of cleaning blind spots due to the need to switch positions to replenish fluid. After the fluid replenishment is completed, the cleaning component 20 can continue to clean along the edge in the outward position until it leaves the obstacle. The fluid replenishment process does not require position switching movement, and the energy consumption of the cleaning equipment is low.

[0071] In this embodiment, the step of providing fluid to the cleaning assembly 20 in response to the first trigger signal further includes:

[0072] During the process of cleaning component 20 moving towards the inward position while cleaning along the edge of an obstacle in its outward position and being resisted by the obstacle, fluid is supplied to cleaning component 20 in response to a first trigger signal. In other words, when cleaning component 20 is in its outward position cleaning along the edge and being resisted by an obstacle, fluid can be supplied to cleaning component 20 at any time as long as the opportunity for fluid replenishment is reached. This improves the cleaning effect of the edge cleaning process and avoids the generation of cleaning blind spots. The fluid replenishment process does not require position switching or reset operations, and the cleaning action appears natural and smooth. There is no situation where the cleaning component 20 cannot replenish fluid due to being passively retracted by the obstacle, making the timing of fluid replenishment more flexible and timely.

[0073] The step of supplying fluid to the cleaning component 20 during the process of cleaning along the edge of the obstacle in the outward position and moving towards the inward position due to the resistance force of the obstacle includes:

[0074] When the cleaning component 20 moves from the outward expansion position to the state of being held in the transition position or the inward retraction position under the squeezing action of the abutment force, fluid is supplied to the cleaning component 20 in response to the first trigger signal.

[0075] Therefore, when the cleaning component 20 is passively moved from the outward position to the transition position or the inward position due to the resistance force of the obstacle, as long as the cleaning component 20 needs to be replenished with fluid, it can be replenished with fluid in a timely manner in response to the first trigger signal, so that the cleaning component 20 can clean the surface to be cleaned in a relatively moist state in the transition position or the inward position, thereby improving the cleaning effect when the cleaning component 20 is passively retracted.

[0076] 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:

[0077] During the process of cleaning component 20 contacting the obstacle and cleaning along the edge of the obstacle, if the contact force applied by the obstacle to cleaning component 20 is removed, fluid can be supplied to cleaning component 20 in response to the first trigger signal during the time period when cleaning component 20 returns from the inward position or transition position to the outward position or when it returns to the outward position.

[0078] Therefore, the cleaning component 20 will not fail to replenish fluid in time when returning to a designated position (such as an outward expansion position or an inward retraction position), ensuring that the cleaning component 20 is always kept in a relatively moist state, thereby improving the moisture level and cleaning effect of the cleaning component 20 from the passive inward retraction position to the outward expansion position.

[0079] 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:

[0080] When the cleaning component 20 is located in an open area away from obstacles and is kept in an inward position, fluid is supplied to the cleaning component 20 in response to a first trigger signal. That is, in this embodiment, even when the cleaning component 20 is not moving along obstacles to clean along the edges, fluid can be supplied to the cleaning component 20 whenever the opportunity to replenish fluid arises, ensuring the humidity and cleaning effect of the cleaning component 20 during the cleaning process in the open area. Specifically, the open area can be an area whose area is larger than the projected outer contour area of ​​the cleaning device along its own height direction by a predetermined value, so that the cleaning device can move freely within this open area without encountering obstacles.

[0081] When the cleaning component 20 is located in an open area away from obstacles, the cleaning device is in a non-edge cleaning state, or a free cleaning state. The non-edge cleaning state or 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 mentioned above.

[0082] In this embodiment, the cleaning component 20 moves from one of the three positions—inward, transition, and outward—to another position by performing a first movement. This first movement can be linear or curvilinear, depending on the drive mechanism that drives the cleaning component 20 to swing; this embodiment does not impose a single limitation. Before the cleaning device drives the cleaning component 20, located at the bottom of the cleaning device, to clean the surface to be cleaned, the method provided in this embodiment further includes the following steps:

[0083] A fluid supply component 30 is provided in the cleaning equipment, and at least one outlet 301 of the fluid supply component 30 is provided on the moving part 50, so that in response to a first trigger signal, the fluid supply component 30 is opened to supply fluid to the cleaning component 20 through at least one outlet 301, wherein the moving part 50 is a structural component provided in the cleaning equipment and capable of performing a first movement action with the cleaning component 20.

[0084] Therefore, in this embodiment, the outlet 301 for the fluid to flow to the cleaning component 20 is located on the moving part 50. Since the moving part 50 can perform the first movement action with the cleaning component 20, that is, the outlet 301 can move with the cleaning component 20. During the process of the cleaning component 20 performing the 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. The fluid flowing out of the outlet 301 can flow directly onto the cleaning component 20, and is not easily thrown out by the collision action of the cleaning component 20 due to dripping to other positions of the cleaning component 20. This prevents the liquid from splashing outside the cleaning component 20 onto the ground, walls, furniture, and other objects, avoiding obvious water stains on the ground, or damage to the walls and furniture by the liquid.

[0085] As can be seen from the above, in this embodiment, when the cleaning component 20 needs to be replenished with fluid, regardless of the position of the cleaning component 20 or the transition between two positions, fluid can be provided to the cleaning component 20 (by opening the fluid supply component 30 to provide the required fluid to the cleaning component 20), so that the cleaning component 20 can be wetted when it is held in the corresponding position or in the transition phase from one position to another.

[0086] When the cleaning component 20 moves along an obstacle to perform edge cleaning, it is controlled to be in an outward or transitional position. Based on a received first trigger signal, fluid is replenished to the cleaning component 20 during edge cleaning, thereby wetting the flexible cleaning element 22 (i.e., the mop). Therefore, during edge cleaning, there is no need to switch to an inward position for fluid replenishment. Fluid replenishment does not require position switching, avoiding blind spots and improving cleaning effectiveness.

[0087] When the cleaning component 20 is pressed against an obstacle, causing it to passively retract under the force of the obstacle, fluid can be replenished to the cleaning component 20 during edge cleaning in response to the received first trigger signal. This wets the cleaning component 20, ensuring it is wetted even when in contact, improving cleaning effectiveness and preventing blind spots. When the cleaning component 20 detaches from the obstacle, fluid can be replenished to the cleaning component 20 in its outward position in response to the received first trigger signal. This wets the cleaning component 20, ensuring cleaning effectiveness and efficiency during edge cleaning and preventing blind spots. When the cleaning component 20 is not moving along the outer edge of the obstacle for edge cleaning, it can be controlled to retract to an inward position. During normal cleaning in the inward position, fluid can be replenished to the cleaning component 20 in response to the received first trigger signal, improving the cleaning effect during normal cleaning.

[0088] The second embodiment of this utility model also provides a cleaning device for performing a cleaning method, the details of which are provided in the first embodiment of this utility model. Figures 2 to 11 The cleaning device includes a body 10, a cleaning component 20, a fluid supply component 30, and a controller 40. The cleaning component 20 is located at the bottom of the body 10 so that it can clean the surface to be cleaned. The fluid supply component 30 is located on the body 10, and the fluid stored in the fluid supply component 30 can be supplied to the cleaning component 20 to wet it.

[0089] The controller 40 is electrically connected to the fluid supply component 30. The controller 40 is configured to open the fluid supply component 30 to supply fluid to the cleaning component 20 in response to a received first trigger signal when the cleaning component 20 is in the retracted position, transition position, or extended position. The controller 40 may include a microcontroller, a single-chip microcomputer, or a central processing unit. The controller 40 may be integrated into a circuit board and mounted within the body 10. The controller 40 may be installed between the fixed housing 11 and the bottom housing 12 of the body 10 to prevent interference and damage from the external environment, thereby improving the safety and reliability of the controller 40.

[0090] In this embodiment, during the cleaning process of the cleaning device moving the cleaning component 20 to clean the surface to be cleaned, the controller 40 can respond to the received first trigger signal to open the fluid supply component 30 to supply fluid to the cleaning component 20 when the cleaning component 20 is in the retracted position, transition position, and outward expansion position, so as to wet the cleaning component 20. That is to say, the cleaning device provided by this application can supply fluid to the cleaning component 20 through the fluid supply component 30 in the retracted position, outward expansion position, and transition position, and can continue to supply fluid to the cleaning component 20 even when it encounters an obstacle and the cleaning component 20 is in the transition position. In this process, since the cleaning component 20 does not need to return to a designated position to supply 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 cleaning areas because it needs to move to a designated position to replenish fluid, and can reduce or even eliminate cleaning blind spots. At the same time, since the cleaning component 20 does not need to be in a designated position to supply fluid, the cleaning device does not need to have a position detection device to detect when the cleaning component 20 is in a designated position to supply fluid, reducing the installation of position detection devices and making the cost and energy consumption of the cleaning device lower.

[0091] The cleaning component 20 moves from one of three positions—an inward-retracting position, a transition position, and an outward-expanding position—to another position by performing a first movement. The fluid supply component 30 includes at least one outlet 301. Figure 3 As shown, the cleaning device also includes a moving part 50, which is disposed on the body 10 and can perform a first movement action with the cleaning component 20. At least one of the moving part 50 and the body 10 is provided with at least one outlet 301. The fluid supply component 30 supplies fluid to the cleaning component 20 through at least one outlet 301.

[0092] In other words, in this embodiment, the outlet 301 for fluid to flow to the cleaning assembly 20 can be provided on the moving part 50 or the body 10, or at least one outlet 301 can be provided on both the moving part 50 and the body 10. So that when the controller 40 opens the fluid supply assembly 30, the fluid supply assembly 30 can flow fluid to the cleaning assembly 20 through at least one outlet 301 on the moving part 50 and / or the body 10 to wet the cleaning assembly 20.

[0093] In this embodiment, when the outlet 301 is located on the moving component 50, the moving component 50 can perform the first movement action with the cleaning component 20, meaning the outlet 301 can move with the cleaning component 20. During the process of the cleaning component 20 performing the first movement action and switching positions, the outlet 301 and the cleaning component 20 can move synchronously. Along the height direction of the cleaning equipment, the outlet 301 remains stationary relative to the cleaning component 20. The fluid flowing out of the outlet 301 can flow directly onto the cleaning component 20, and is less likely to be splashed out by the collision action of the cleaning component 20 due to dripping to other positions, thus preventing liquid from splashing outside the cleaning component 20 onto the ground, walls, furniture, and other objects, avoiding obvious water stains on the ground, or damage to walls and furniture by liquid immersion.

[0094] In this embodiment, when at least one outlet 301 is disposed on the body 10, the cleaning component 20 is provided with a flow guiding structure 213. When the cleaning component 20 is respectively located in the inward position, the transition position, and the outward position, along the height direction of the body 10, the flow guiding structure 213 has an inward vertical projection area, a transition vertical projection area, and an outward vertical projection area at the bottom of the body 10. At least a portion of the outlet 301 is located in a first overlapping area where the inward vertical projection area, the transition vertical projection area, and the outward vertical projection area overlap. The first overlapping area is... Figure 4 The outlet is located in the shaded area. Therefore, regardless of whether the cleaning component 20 is in the inward, transitional, or outward position, since the outlet 301 is at least partially located in the vertical projection area at the bottom of the body 10, fluid can flow along the outlet 301 to the cleaning component 20 in any position to wet it. Of course, it is preferable that the outlet 301 is entirely located in the vertical projection area of ​​the corresponding position, which reduces fluid waste and ensures adequate wetting of the cleaning component 20.

[0095] In this embodiment, the cleaning assembly 20 includes a support 21 and a flexible cleaning element 22. Along the height direction of the body 10 (e.g., ... Figure 6 (In the direction indicated by the middle arrow Y), the flexible cleaning element 22 is disposed on the surface of the support 21 away from the body 10. The flow guiding structure 213 is disposed on the support 21, such as... Figure 3As shown, the flow guiding structure 213 in this embodiment may include a plurality of first through holes 132. Along the height direction of the body 10, the plurality of first through holes 132 are disposed on the side of the bracket 21 near the body 10 and arranged circumferentially along the bracket 21. Therefore, when the cleaning component 20 is in the retracted position, transition position, and outward expansion position, it is sufficient to ensure that at least a portion of the outlet 301 is located within the vertical projection area of ​​at least one first through hole 132 on the body 10. This ensures that at least a portion of the outlet 301 is always aligned with the first through hole 132. If the fluid includes water, the water can fall directly into at least one first through hole 132 along the outlet 301, thereby contacting the flexible cleaning component 22 and wetting it. The flow guiding structure 213 may also include a flow guiding groove 131, which is disposed on the side of the bracket 21 near the body 10. The bottom of the flow guiding groove 131 may be provided with a first through hole 132. Therefore, when the cleaning component 20 is in the retracted position, transition position, and outward expansion position, it is only necessary to ensure that at least a portion of the outlet 301 is located in the vertical projection area of ​​the guide channel 131 on the body 10. This ensures that at least a portion of the outlet 301 can always be aligned with the groove and guide the fluid to the guide channel 131, and then flow to the flexible cleaning component 22 through the first through hole 132 at the bottom of the guide channel 131. When the bracket 21 is connected to the drive shaft 62 of the drive component 60, the guide channel 131 can be arranged circumferentially around the drive shaft 62, thereby further ensuring that at least a portion of the outlet 301 can always be aligned with the guide channel 131. Moreover, the guide channel 131 is simple and convenient to start, and can reduce the weight of the bracket 21, thereby reducing the difficulty of driving the bracket 21 by the drive component 60.

[0096] The first through hole 132 may not be located at the bottom of the guide channel 131, but may be located on the bracket 21 at a position offset from the guide channel 131. The first through hole 132 and the guide channel 131 can be connected by a connecting pipe or a channel opened on the bracket 21.

[0097] When at least one outlet 301 is provided on the moving member 50, the cleaning assembly 20 is provided with a flow guiding structure 213. Along the height direction of the body 10, at least a portion of the projected outer contour of the outlet 301 is located within the projected outer contour of the flow guiding structure 213. Therefore, during the initial movement of the moving member 50 along with the cleaning assembly 20, at least a portion of the outlet 301 can correspond to the flow guiding structure 213, thereby ensuring that fluid can flow from the outlet 301 into the flow guiding structure 213 and thus wet the cleaning assembly 20. Regardless of the location of the cleaning assembly 20, fluid replenishment can be achieved through the outlet 301.

[0098] like Figure 6As shown, the main body 10 includes a top shell 11 and a bottom shell 12, with the bottom shell 12 located at the bottom of the top shell 11. Along the height direction of the main body 10, the cleaning component 20 is located at the bottom of the bottom shell 12, and the bottom shell 12 is provided with a first clearance hole 121. The moving component 50 includes a sealing plate 51, and the cleaning device also includes a drive component 60.

[0099] The drive assembly 60 includes a drive component 61 and a drive shaft 62. Along the height direction of the body 10, the drive component 61 is located on the side of the bottom shell 12 away from the cleaning assembly 20 and can perform a first movement relative to the bottom shell 12 with the cleaning assembly 20. The drive shaft 62 is connected to the drive component 61 and can move in a first clockwise direction (e.g., ...) under the drive of the drive component 61. Figure 6 Rotate in the direction indicated by arrow S, with the first clockwise direction being either clockwise or counterclockwise.

[0100] A sealing plate 51 is disposed between the cleaning assembly 20 and the drive component 61 and covers the first clearance hole 121. One end of the drive shaft 62, away from the drive component 61, passes through the first clearance hole 121 and the sealing plate 51 and connects to the cleaning assembly 20, enabling the drive shaft 62 to drive the cleaning assembly 20 to rotate in a first clockwise direction for cleaning. At least one outlet 301 is located on the sealing plate 51 relative to the first clearance hole 121. The drive component 61 can be electrically connected to a controller 40 to control the drive component 61 to start driving the cleaning assembly 20 to rotate. The drive component 61 can also be electrically connected to another control circuit. Specifically, the drive component 61 may include a housing, a gear transmission system, and a motor. The gear transmission system is installed in the mounting space within the housing, and the motor is mounted on the housing. The gear transmission system is drively connected between the motor's rotating shaft and the drive shaft 62.

[0101] like Figures 6 to 9 As shown, in this embodiment, when the moving component 50 includes a sealing plate 51, during the first movement of the cleaning assembly 20, the sealing plate 51 can dynamically seal the space between the inner circumferential surface of the first clearance hole 121 and the drive shaft 62, preventing liquid from splashing into the body 10 through the first clearance hole 121. This avoids short circuits or even burnout of the drive component 61 and other electronic components inside the body 10 due to contact with liquid, thus extending the service life of the cleaning equipment. Specifically, the sealing plate 51 can be fixedly connected to the drive component 61 and / or rotatably connected to the bottom shell 12, allowing the sealing plate 51 to move with the drive component 61 and the cleaning assembly 20. Dynamic setting of the outlet 301 can be achieved without adding additional components, ensuring that the outlet 301 is always aligned with the guide structure 213, making the overall structure of the cleaning equipment more compact and reliable.

[0102] Specifically, when the flow guiding structure 213 includes at least one first through hole 132, the cleaning assembly 20 includes a bracket 21 and a flexible cleaning element 22. The bracket 21 is connected to the drive shaft 62. At least one first through hole 132 is disposed through the bracket 21 along the height direction of the body 10. The flexible cleaning element 22 is disposed on the surface of the bracket 21 away from the body 10. When the cleaning assembly 20 is in the retracted position, the first through hole 132 has a first projected outer contour on the sealing plate 51 along the height direction of the body 10; when the cleaning assembly 20 is in the expanded position, the first through hole 132 has a second projected outer contour on the sealing plate 51 along the height direction of the body 10. The first projected outer contour and the second projected outer contour have a second overlapping area (e.g., ...). Figure 5 (The shaded area in the image), Exit 301 is located in the second overlapping area.

[0103] Therefore, when the cleaning component 20 is in any of the following positions—the inward position, the transition position, and the outward position—or during the process of moving from one position to another (such as during the movement between the inward and outward positions), the fluid can accurately enter the first through hole 132 through the outlet 301 and flow onto the flexible cleaning component 22. This allows for the replenishment of liquid to the cleaning component 20 at any time, while preventing the liquid from flowing to rigid structural positions on the support 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 support 21, etc.) and splashing onto the ground. This effectively prevents the ground that has already been cleaned by the cleaning equipment from being contaminated by the liquid, achieving an ideal cleaning effect and providing a better user experience.

[0104] In this embodiment, during the first movement of the cleaning component 20, while the cleaning component 20 is also performing a first rotational movement in the first clockwise direction, to ensure that the outlet 301 is always located within the second overlapping area, the flow guiding structure 213 (such as the first through hole 132) has a length L1 in the first clockwise direction. When the cleaning component 20 moves from the inward position to the outward position or from the outward position to the inward position, the arc distance generated by the flow guiding structure 213 along the first clockwise direction as the cleaning component 20 performs its first rotational movement is L2, such as... Figure 5 As shown, L1 is greater than L2. It can be understood that the length L1 of the flow guiding structure 213 along the first clockwise direction is the length of the first through hole 132.

[0105] Therefore, during the first movement and rotation of the cleaning component 20, since L1 is greater than L2, after the outlet 301 moves to the inward or outward position with the sealing plate 51, the outlet 301 can always be located in the second overlapping area, thereby effectively preventing liquid from splashing onto the ground during the first movement of the cleaning component 20.

[0106] When the fluid includes liquids (such as water or a mixture of water and detergent), and the cleaning component 20 in this embodiment includes a support 21 and a flexible cleaning element 22, the moving component 50 may also include the support 21, with at least one outlet 301 disposed on the support 21. Therefore, during the first movement of the cleaning component 20, at least one outlet 301 on the support 21 will move along with the movement of the cleaning component 20. Thus, the position of the outlet 301 supplying liquid to the flexible cleaning element 22 relative to the flexible cleaning element 22 remains constant, and the liquid flowing from the outlet 301 can flow directly onto the flexible cleaning element 22 without dripping onto other parts of the cleaning component 20, preventing liquid splashing onto the floor, walls, furniture, etc., and ensuring the water content of the flexible cleaning element 22, reducing liquid waste.

[0107] Specifically, the outlet 301 on the support 21 can be at least one of a nozzle, spray head, water pipe connector, etc., provided on the support 21 and capable of aligning with the flexible cleaning element, with the nozzle directly communicating with the fluid supply assembly 30. The outlet 301 may also include a through-hole structure that extends through the support 21. Thus, liquid from the fluid supply assembly 30 can flow directly along the through-hole structure to the flexible cleaning element 22, fully wetting it. Furthermore, the outlet 301 of this through-hole structure is easy to manufacture and can reduce the overall weight of the support 21, avoiding overload or high failure rates due to fatigue of the power source driving the support 21 (such as the drive assembly 60 mentioned herein).

[0108] In this embodiment, when the outlet 301 on the support 21 is a through-hole structure, another outlet 301 can be provided on the sealing plate 51 as mentioned above to correspond to the through-hole structure. This allows the liquid provided by the fluid supply component 30 to flow through the outlet 301 on the sealing plate 51 to the through-hole structure on the support 21. This eliminates the need for operations during the rotational connection between the through-hole structure and the fluid supply component 30, and avoids increasing the complexity of the cleaning component 20 structure.

[0109] In some implementations, such as Figure 8 and Figure 9 As shown, the cleaning device also includes a drive assembly 60, which includes a drive component 61 and a transmission shaft 62. Along the height direction of the body 10, the drive component 61 is disposed on the body 10 and can perform a first movement relative to the body 10 with the cleaning assembly 20. The transmission shaft 62 is connected to the drive component 61 and can rotate in a first clockwise direction under the drive of the drive component 61. The end of the transmission shaft 62 away from the drive component 61 is connected to the cleaning assembly 20 and can perform the first movement. The moving component 50 may also include the transmission shaft 62, and at least one outlet 301 is disposed on the transmission shaft 62.

[0110] Therefore, in this embodiment, at least one outlet 301 of the fluid supply component 30 can also be provided on the drive shaft 62. The fluid supply component 30 flows fluid to the cleaning component 20 along at least one outlet 301. During the first movement of the cleaning component 20, since the drive shaft 62 can move along with the first movement of the cleaning component 20, the outlet 301 will also move along with the movement of the drive shaft 62 and the cleaning component 20. Therefore, the position of the outlet 301 relative to the cleaning component 20 remains unchanged, and the fluid flowing out of the outlet 301 can flow directly onto the cleaning component 20 without flowing to places other than the cleaning component 20. Especially when the fluid includes liquid, it can prevent liquid from splashing onto the ground, walls, furniture, etc., further improving the cleaning effect when replenishing the cleaning component 20 with fluid at any time, as well as the user experience.

[0111] like Figure 8 As shown, the drive shaft 62 in this embodiment may include a first shaft segment 621 and a second shaft segment 622. The first shaft segment 621 is drively connected to the drive component 61 and can rotate around its own axis under the drive of the drive component 61. The second shaft segment 622 is connected to the end of the first shaft segment 621 away from the drive component 61. To ensure that the fluid from the fluid supply component 30 can flow into the outlet 301 on the drive shaft 62 and to reduce the complexity of the connecting pipes, the second shaft segment 622 may include a rotating connector 221 and a shaft body 222. The rotating connector 221 is a cylindrical structure. Figure 8 and Figure 9 As shown, the rotary connector 221 is provided with a first inlet 231, which communicates with the fluid supply assembly 30. Specifically, it can be connected to the heater 313 or the water pump 312 of the fluid supply assembly 30 via a hose. Along the axial direction of the first shaft segment 621, the rotary connector 221 is provided with a second through hole 232. The second through hole 232 is sleeved on the outer periphery of the shaft body 222 and surrounds the shaft body 222 to form a mounting groove 241 (e.g., ...). Figure 9 (As shown). The rotating connector 221 is rotatable relative to the shaft body 222 about the axis of the shaft body 222. At least one outlet 301 is provided on the shaft body 222, and the mounting groove 241 communicates between the first inlet 231 and at least one outlet 301.

[0112] The rotating connector 221 has a first state of movement relative to the body 10 and a second state of being stationary relative to the body 10. In the first state, the rotating connector 221 can perform a first movement action with the cleaning assembly 20. When the cleaning assembly 20 is held in an inward position, a transition position, or an outward position, the rotating connector 221 is held in the second state, and the shaft body 222 can rotate relative to the rotating connector 221 under the drive of the drive component 61. Thus, after the fluid enters the first inlet 231, it flows along the mounting groove 241 into at least one outlet 301 on the shaft body 222. By connecting this outlet 301 to the guide structure 213 on the support 21 of the cleaning assembly 20, during the first rotational movement of the cleaning assembly 20 driven by the drive shaft 62 for cleaning, the fluid can dynamically flow into the outlet 301 and then through the outlet 301 to the guide structure 213, achieving wetting of the cleaning assembly 20. In this structure, since the rotating connector 221 and the shaft body 222 are rotatably connected, dynamic fluid transmission is achieved, and the overall structure is compact and reliable. Secondly, to improve the sealing performance during dynamic fluid transfer, such as Figure 8 As shown, along the axial direction of the shaft body 222, a seal 623 can be respectively provided on both sides of the mounting groove 241. The seal 623 and the inner wall of the mounting groove 241 form a sealed flow guiding space. At this time, the fluid can be safely and reliably guided to the cleaning component 20 without leakage. The seal 623 may include at least one of the following: a flexible rubber ring, a silicone ring, or a fluororubber ring.

[0113] like Figure 8 and Figure 9 As shown, a stop structure 70 can be provided between the rotating connector 221 and the body 10 to hold the rotating connector 221 in a second state, such as when the drive shaft 62 needs to pass through the sealing plate 51 to connect with the cleaning assembly 20. The stop structure 70 can be provided between the sealing plate 51 and the rotating connector 221. The stop structure 70 may include a stop groove 71, a second clearance hole 72, and a stop protrusion 73. The second clearance hole 72 is provided through the sealing plate 51 along the axial direction of the drive shaft 62 so that the shaft body 222 of the drive shaft 62 can pass through the second clearance hole 72 to connect with the cleaning assembly 20. Along the radial direction of the drive shaft 62, the stop groove 71 is recessed into the inner wall surface of the second clearance hole 72. The stop protrusion 73 is provided on the side of the rotating connector 221 near the stop groove 71 and is at least partially located within the stop groove 71. The stop protrusion 73 can be integrally formed with the rotating connector 221 or welded to the rotating connector 221. When the drive shaft 62 moves with the cleaning component 20, the sealing plate 51 and the rotating connector 221 move synchronously with the drive shaft 62. At this time, the rotating connector 221 moves relative to the body 10 (i.e., it is in the first state).

[0114] When the drive shaft 62 moves with the cleaning assembly 20 to the inward, transition, or outward position, the stop groove 71 and the stop protrusion 73 abut together along the circumference of the drive shaft 62. At this time, the rotating connector 221 is stationary relative to the body 10 and remains in the second state, while the shaft body 222 rotates relative to the rotating connector 221 under the drive of the drive component 61, so that the fluid can enter the mounting groove 241 from the first inlet 231 and be dynamically transferred 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, low complexity, and convenient assembly.

[0115] like Figure 8 As shown, a connector 731 can be installed on the side of the stop protrusion 73 near the top shell 11. The first inlet 231 is located inside the connector 731, and a guide channel 732 connecting the first inlet 231 and the mounting groove 241 is provided inside the stop protrusion 73. Thus, by simply connecting the connector 731 and the heater 313 or the water pump 312 through a pipe, fluid can enter the outlet 301 along the first inlet 231, the guide channel 732, and the mounting groove 241, and then flow from the outlet 301 to the cleaning component 20, making assembly efficient and convenient. Figure 6 The arrows in the diagram illustrate the flow path of the fluid to the cleaning component 20.

[0116] When the outlet 301 is mounted on the drive shaft 62, the bracket 21 may include a top cover 211 and a chassis 212. The flow guiding structure 213 also includes a flow guiding cavity. The top cover 211 and the chassis 212 enclose a flow guiding cavity communicating with the outlet 301, and a first through hole 132 may be provided at the bottom of the flow guiding cavity. After the fluid enters the flow guiding cavity from the outlet 301, it flows directly from the first through hole 132 to the flexible cleaning component 22, further ensuring the fluid transmission sealing and avoiding fluid leakage. A groove may be provided on at least one side of the chassis 212 and the top cover 211 near the other side, so that the flow guiding cavity is formed after the chassis 212 and the top cover 211 are fastened together, making the assembly convenient and efficient. The chassis 212 may include a main body and a flexible outer ring. The flexible outer ring is located on the outer periphery of the main body and is used to mitigate the impact force of the bracket 21 on obstacles, preventing the bracket 21 and / or obstacles (such as furniture or walls) from being damaged. Both the main body and the flexible outer ring can be equipped with a flow guiding structure 213.

[0117] In some embodiments, the body 10 includes a top shell 11 and a bottom shell 12, the bottom shell 12 being disposed at the bottom of the top shell 11 and enclosing the top shell 11 to form an installation space, and at least one outlet 301 being disposed in the bottom shell 12. Figure 3 and Figure 10It is understood that the fluid supply component 30 includes a fluid supply part 31 and a connecting part 32. The fluid supply part 31 is disposed within the installation space and electrically connected to the controller 40. The connecting part 32 includes a water inlet 321 and a cover plate 322. The cover plate 322 covers the bottom shell 12 on the side near the top shell 11 and forms a water supply channel 220 with the bottom shell 12. The water inlet 321 is disposed on the cover plate 322 and communicates 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 communicate with the heater 313. Along the height direction of the body 10, at least one outlet 301 is located at the bottom of the water supply channel 220 and communicates with the water supply channel 220. After the controller 40 opens the fluid supply part 31, fluid flows through the connecting part 32 into at least one outlet 301 and then reaches the cleaning component 20. In this embodiment, the outlet 301 is disposed at the bottom of the water supply channel 220, which is convenient and simple to process. Furthermore, since the water supply channel 220 is formed by the cover plate 322 that is fastened to the bottom shell 12, it is easy to assemble and has low cost.

[0118] In some embodiments, when at least one outlet 301 is provided on the body 10, the fluid supply assembly 30 includes a fluid supply component 31 and a communication component 32. The fluid supply component 31 is provided on the body 10 and electrically connected to the controller 40. Figure 11 As shown, the connecting component 32 includes a connecting element 323 and a connecting pipe 324. The connecting element 323 is disposed on the body 10 and communicates with at least one outlet 301. One end of the connecting pipe 324 is communicated with the fluid supply component 31, and the other end is communicated with the connecting element 323. After the controller 40 opens the fluid supply component 31, fluid flows into the connecting element 323 through the connecting pipe 324, and is then guided to the outlet 301 through the connecting element 323. The connecting pipe 324 can be a flexible hose or a rigid pipe, and the connecting element 323 can be a two-way connector or a three-way connector, etc. This structure of the connecting component 32 is convenient to assemble and inexpensive.

[0119] like Figure 6As shown, 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 a controller 40, enabling the controller 40 to control the opening and closing of the water pump 312 to allow water in the water tank 311 to flow to the outlet 301. The heater 313 is connected to a connecting component 32. The heater 313 may be electrically connected to the controller 40, allowing the controller 40 to also control the heater 313 to heat the water from the water tank 311 to warm or hot water. When the fluid includes at least one of warm or hot water, in addition to wetting the cleaning component 20, it also enhances the cleaning component 20's ability to dissolve stubborn stains (such as grease), thereby better cleaning stubborn stains. Secondly, due to the higher temperature of the hot water, it can also effectively kill bacteria and mites on the cleaning component 20, achieving the purpose of disinfection and sterilization.

[0120] At least one outlet 301 is configured to correspond to at least two sets of cleaning components 20, so that water can be supplied to at least two sets of cleaning components 20 simultaneously through at least one outlet 301. Alternatively, at least two outlets 301 can be configured to correspond one-to-one with at least two sets of cleaning components 20, that is, each set of cleaning components 20 can correspond to at least one outlet 301. In addition, at least one set of cleaning components 20 can be configured to correspond to at least two outlets 301, that is, a cleaning component 20 can be supplied with water simultaneously through at least two outlets 301, further improving the efficiency of wetting the cleaning component 20.

[0121] In some embodiments, when the cleaning component 20 has an inward position, a transition position, and an outward position, the cleaning device further includes a drive component 60 and a stop component 80, wherein the drive component 60 is connected to the cleaning component 20 to drive the cleaning component 20 to rotate. For example... Figure 12 A stop component 80 is disposed on the drive assembly 60. The stop component 80 is configured such that, during the process of cleaning the cleaning assembly 20 in the outward position and cleaning along the edge of an obstacle, when the stop component 80 is subjected to a reaction force (or abutment force) exerted by the obstacle, it drives the cleaning assembly 20 to move towards the inward position. Obstacles include walls, inner corners, outer corners, furniture corners, etc. If the cleaning equipment drives the cleaning assembly 20 from one side of an inner corner (such as a corner greater than 60 degrees) to another side, and if the stop component 80 is subjected to a reaction force exerted by the wall surface where the other side of the inner corner is located, the stop component 80 will drive the cleaning assembly 20 from the outward position to the inward position under the action of the reaction force. When the reaction force is removed, the cleaning assembly 20 can return to the outward position and continue cleaning along the edge.

[0122] Therefore, in this embodiment, by providing a stop member 80, when the cleaning component 20 extends outward to its outermost edge protruding from the body 10 in a predetermined direction to clean the edges of obstacles such as walls and furniture, if the cleaning component 20 is relatively close to the obstacle, the stop member 80 can contact the obstacle, thereby preventing the cleaning component 20 from making hard contact with the obstacle and avoiding scratching it. At the same time, the stop member 80, under the force exerted by the obstacle, can cause the entire drive component 60 to swing, so that the drive component can drive the cleaning component 20 to move towards the inward position to achieve inward retraction. It can be seen that the cleaning device in this embodiment not only facilitates edge cleaning of obstacles, but also does not easily scratch the obstacles.

[0123] When the drive assembly 60 includes a drive component 61 and a drive shaft 62, and the housing of the drive component 61 extends at least partially along the axial direction of the drive shaft 62 to a position near the cleaning assembly 20, then the stop component 80 can be connected to the side of the housing of the drive component 61 near the cleaning assembly 20.

[0124] When the cleaning assembly 20 includes a support 21 and a flexible cleaning element 22, the stop member 80 includes a stop plate 81, which at least partially protrudes from the outer edge of the support 21 within the projection of the body 10 in the height direction. Thus, when the cleaning assembly 20 expands to its expanded position, the stop plate 81 can contact the obstacle before the rigid support 21 on the cleaning assembly 20, preventing the rigid support 21 from abrading the obstacle during the cleaning operation.

[0125] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0126] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0127] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
