[0002] Cleaning equipment refers to mechanical devices used for cleaning various places and items. Taking robotic vacuum cleaners as an example, most robotic vacuum cleaner base stations on the market currently adopt a boiling and washing drum design.

However, this design has certain limitations, especially when solid debris adheres to the surface of the drum. This debris can easily remain inside the cleaning tank, requiring manual intervention from the user for cleaning and maintenance. This design still needs improvement in terms of cleaning efficiency and user experience. Therefore, seeking a more efficient solution to these problems is particularly necessary.

[0051] Most robotic vacuum cleaner base stations on the market currently use a boiling and washing drum design. The specific operation involves adding water to the cleaning tank of the base station's cleaning disc assembly, and then heating the cleaning components (such as the drum) placed inside via a PTC heater located at the bottom of the tank, thereby raising the water temperature to achieve the cleaning purpose. How to handle the heated wastewater is a problem that urgently needs to be solved.

[0052] This invention proposes a cleaning tray assembly, which aims to solve the problem that existing cleaning equipment's cleaning tray assemblies cannot automatically discharge solid waste.

[0053] Please see Figures 1 to 3In one embodiment of the present invention, the cleaning tray assembly 100 has a water inlet a, and the cleaning tray assembly 100 includes a base 1 and a cleaning tray 2. The base 1 is used to connect to a base station. The upper end of the cleaning tray 2 is recessed with a cleaning groove 2a, which is connected to the water inlet a. The cleaning tray 2 is rotatably connected to the base 1 about a rotation axis extending in a first horizontal direction. The cleaning tray 2 has a first working position and a second working position during its rotation stroke. In response to the cleaning tray 2 switching from the first working position to the second working position, the sewage in the cleaning groove 2a is driven to flow.

[0054] Understandably, the base 1 is used to connect with the base station of the cleaning equipment to achieve stable fixation of the overall structure and functional cooperation. The cleaning tray 2 is set on the base 1, and a cleaning groove 2a is recessed at its upper end. The cleaning groove 2a is connected to the water inlet a so that external water can flow into the cleaning groove 2a through the water inlet a for subsequent rinsing of the cleaning objects such as the roller.

[0055] The cleaning disc 2 is rotatably connected to the base 1 about a rotation axis extending in a first horizontal direction. This rotation axis is arranged in a horizontal direction. The rotation axis of the cleaning disc 2 can be located in the middle region of the cleaning disc 2, or near one end of the cleaning disc 2, or near the bottom of the cleaning disc 2, to ensure that the cleaning disc 2 can effectively drive the liquid in the cleaning tank 2a to flow during rotation.

[0056] It should be noted that the "first horizontal direction" refers to a direction parallel to the ground, which constitutes the axis of rotation of the cleaning disc 2. Further, the first horizontal direction can be understood as the transverse or longitudinal direction in the overall structural layout of the cleaning equipment; for example, it can be left-right (i.e., the width of the equipment) or front-back (i.e., the depth of the equipment), depending on the internal spatial arrangement of the base station and the installation position and functional requirements of the cleaning disc assembly 100.

[0057] The "first horizontal direction" is not limited to a fixed direction, but can be flexibly adjusted according to the actual product design requirements, as long as the cleaning disc 2 can rotate around this direction as a reference and effectively drive the sewage in the cleaning tank 2a to flow. Therefore, whether the cleaning disc 2 rotates around a horizontal axis in the left-right or front-back direction, it falls within the protection scope of the technical solution described in this utility model.

[0058] The cleaning disc 2 has two working positions during its rotation stroke: a first working position and a second working position. The first working position is the initial stationary state of the cleaning disc 2, at which time the cleaning tank 2a is in a relatively stationary state, which facilitates water intake or other operations. When the cleaning disc 2 switches from the first working position to the second working position, the cleaning disc 2 rotates at a certain angle, which drives the sewage in the cleaning tank 2a to flow, thereby discharging the sewage carrying solid waste from the tank.

[0059] Specifically, after a cleaning task is completed, for example, the roller is placed in the cleaning tank 2a for rinsing, at which point sewage and solid waste remain in the cleaning tank 2a. The control system activates the drive mechanism (not shown) or controls the movement of the cleaning components being cleaned, thereby causing the cleaning disc 2 to rotate around the aforementioned axis of rotation, moving it from the first working position to the second working position. Because the cleaning tank 2a rotates synchronously with the cleaning disc 2, the liquid inside the tank flows due to gravity and inertia, allowing larger particles in the sewage to be smoothly discharged under the influence of the water flow, preventing them from settling at the bottom of the cleaning tank 2a. This process requires no manual intervention, achieving automatic discharge of solid waste.

[0060] In addition, the rotation angle of the cleaning plate 2 can be set according to actual needs, for example, it can be controlled between 15° and 45° to ensure the effectiveness of liquid flow and avoid excessive rotation that could cause structural interference.

[0061] By rotating the cleaning disc 2 around a rotation axis extending in the first horizontal direction, the cleaning tank 2a rotates in a specific direction under the influence of the cleaning disc 2. This changes the static distribution of the liquid within the cleaning tank 2a, causing the wastewater to form local eddies or directional flow. This allows larger solid waste to be carried away by the water flow in a timely manner, preventing blockages or residue. Furthermore, by making full use of the spatial layout, the rotational movement of the cleaning disc 2 achieves dynamic control of the liquid inside the cleaning tank 2a without increasing the size of the base station, meeting the efficient drainage requirements of the compact space of the robotic vacuum cleaner base station.

[0062] Furthermore, the cleaning tray assembly 100 also has a first drain outlet b and a second drain outlet c; in the first working position, the cleaning tank 2a is connected to the water inlet a and the first drain outlet b; in the second working position, the cleaning tank 2a is connected to the water inlet a and the second drain outlet c.

[0063] Thus, the cleaning disc 2 is rotatably connected to the base 1 around a rotation axis extending in the first horizontal direction, and can switch to two important working positions during its rotation stroke: a first working position and a second working position. When the cleaning disc 2 is in the first working position, the cleaning tank 2a is in fluid communication with the water inlet a and the first drain outlet b. At this time, water can be injected into the cleaning tank 2a for the initial normal rinsing operation of the cleaning objects such as the drum, and the residual sewage can be discharged through the first drain outlet b. When the cleaning disc 2 rotates to the second working position, the cleaning tank 2a deflects relative to the initial position, causing the liquid inside to flow due to gravity and inertia. At the same time, the cleaning tank 2a is connected to the water inlet a and the second drain outlet c, so that the sewage containing solid waste can be concentrated and discharged into the subsequent sewage treatment system or recycling container through the second drain outlet c.

[0064] In this embodiment, the first drain outlet b and the second drain outlet c are both integrated on the cleaning tray assembly 100 itself. Unlike designs that place the drain outlets on the base station body or other external structures, this utility model not only simplifies the pipeline connection of the overall system, but also improves the controllability and sealing of the drainage path.

[0065] In addition, since the sewage outlet is directly set on the cleaning tray assembly 100, it can more accurately match the liquid distribution state of the cleaning tank 2a at different working positions, so as to achieve effective classification, discharge and collection of sewage at different stages.

[0066] Preferably, the first discharge outlet b is used to discharge relatively clean initial flushing wastewater, such as clean water containing only a small amount of suspended particles, while the second discharge outlet c is used to discharge later wastewater containing larger solid waste.

[0067] By setting the drain outlet on the structure of the cleaning tray assembly 100 itself, it can respond more flexibly to changes in the liquid distribution of the cleaning tank 2a at different working positions, so that the sewage can be discharged at the required time and along the optimal path.

[0068] Furthermore, in order to achieve automatic reset of the cleaning disc 2, in this embodiment, the cleaning disc assembly 100 also includes a reset member 3, which is used to reset the cleaning disc 2 from the second working position to the first working position.

[0069] It is understandable that the reset element 3 can be an elastic element, such as a torsion spring, tension spring or rubber pad, which has the ability to store and release energy.

[0070] In a preferred embodiment of this utility model, the reset member 3 adopts a rectangular spring structure. The rectangular spring has a large contact area and is disposed between the bottom of the cleaning tray 2 and the base 1. The rectangular spring extends along the first horizontal direction, and its width direction is adapted to the overall width of the cleaning tray 2, covering as much of the bottom area of ​​the cleaning tray 2 as possible, reducing shaking or jamming caused by uneven force, so as to achieve uniform force and stable reset.

[0071] Specifically, one end of the reset member 3 is fixedly connected to the base 1, and the other end acts on the cleaning disc 2. When the cleaning disc 2 is pressed down by the roller and rotates from the first working position to the second working position, the reset member 3 is compressed or twisted and stores a certain amount of elastic potential energy. When the roller rises away from the cleaning disc 2, the reset member 3 releases the stored energy and pushes the cleaning disc 2 to rotate in the opposite direction around the rotation axis extending in the first horizontal direction, so that it returns to the initial first working position.

[0072] By setting a reset component 3, the cleaning disc 2 can automatically return to its initial state after each sewage discharge operation without the need for additional drive devices or manual intervention.

[0073] Furthermore, in order to facilitate the collection of sewage and solid waste, in this embodiment, the cleaning pan assembly 100 also includes a water receiving pan 4, the upper end of which is open to form a second sewage outlet c; the water receiving pan 4 is located below the cleaning pan 2 and is used to receive sewage poured from the cleaning tank 2a when the cleaning pan 2 switches from the first working position to the second working position and is in the second working position.

[0074] It is understandable that the water receiving tray 4 is fixedly connected to the support structure of the base 1 or the cleaning equipment base station. When the cleaning tray 2 is in the first working position, the cleaning tank 2a remains initially stationary and the liquid inside is still. When the cleaning tray 2 rotates to the second working position around the rotation axis extending in the first horizontal direction, the cleaning tank 2a tilts, and the sewage in the tank flows to the lower side due to gravity and is discharged from the second drain port c. Since the water receiving tray 4 is set directly below the cleaning tray 2, it can collect the sewage poured out from the cleaning tank 2a. The discharged sewage can be accurately received and orderly discharged to prevent liquid from splashing or leaking to other component areas and avoid secondary pollution problems caused by sewage overflow, splashing or residue.

[0075] Furthermore, in order to ensure the sealing performance of the cleaning disc 2 when it is in the first working position, in this embodiment, the base 1 includes a bottom 10 and a side enclosure 20 connected to the outer periphery of the bottom 10. The cleaning disc 2 has a first end 21 that rotates about its rotation axis. A sealing member 5 is provided between the first end 21 of the cleaning disc 2 and the side enclosure 20. When the cleaning disc 2 is in the first working position, the sealing member 5 is used to seal between the first end 21 of the cleaning disc 2 and the side enclosure 20. When the cleaning disc 2 is in the second working position, the first end 21 of the cleaning disc 2 is offset from the sealing member 5 and is located below the sealing member 5, so as to form a drain gap d between the cleaning disc 2 and the sealing member that communicates with the second drain outlet c.

[0076] Understandably, the base 1 consists of a bottom 10 and a side circumference 20 connected to the outer periphery of the bottom 10, forming an overall ring or semi-ring structure, which provides support and limit for the cleaning tray 2.

[0077] The first end 21 of the cleaning disc 2 is a side edge region near its rotation axis. A sealing element 5 is provided between this region and the side enclosure 20. Specifically, the sealing element 5 can be made of a flexible material, such as a rubber ring, silicone strip or a flexible material with elasticity, so that it has good adaptability and compensation ability in the sealed state, and avoids leakage caused by minor deformation of the cleaning disc 2 due to manufacturing errors or assembly deviations.

[0078] When the cleaning disc 2 is in the first working position, that is, the cleaning tank 2a is initially stationary, the first end 21 of the cleaning disc 2 is in close contact with the sealing element 5, forming a good sealing effect to ensure that water will not leak from the connection between the cleaning disc 2 and the base 1 during the water intake process.

[0079] When the cleaning disc 2 rotates to the second working position around its first horizontal axis of rotation, the cleaning disc 2 tilts, and its first end 21 rises and gradually disengages from the seal 5, moving below the seal 5, thus forming a drain gap d between the cleaning disc 2 and the seal 5. This drain gap d, as part of a fluid channel, connects the interior of the cleaning tank 2a and the second drain outlet c, allowing wastewater to pass smoothly through the gap and drain into the receiving tray 4 or other subsequent drainage structures under gravity.

[0080] Preferably, the shape of the seal 5 is adapted to at least a portion of the contour of the cleaning disc 2 to ensure a close fit in the first working position; at the same time, when the cleaning disc 2 rotates to the second working position, the seal 5 also avoids interfering with its movement, thereby ensuring smooth operation.

[0081] Specifically, in one embodiment, the sealing member 5 includes a main body 51 and an overlapping portion 52, the overlapping portion 52 protruding from the side of the main body 51 facing the cleaning tray 2; when the cleaning tray 2 is in the first working position, the first end 21 of the cleaning tray 2 overlaps with the overlapping portion 52.

[0082] When the cleaning disc 2 is in the first working position, that is, the cleaning tank 2a is kept horizontal, the first end 21 of the cleaning disc 2 overlaps downward on the surface of the overlapping part 52, so that the two are tightly fitted, thereby forming a good seal between the cleaning disc 2 and the base 1.

[0083] When the cleaning disc 2 rotates to the second working position around the rotation axis extending in the first horizontal direction, the cleaning disc 2 tilts, and the first end 21 descends and disengages from the overlapping part 52, instead being located below the overlapping part 52. At this time, a sewage discharge gap d is formed between the cleaning disc 2 and the overlapping part 52. Sewage can flow out through this gap and is eventually discharged through the second sewage outlet c.

[0084] Furthermore, in order to ensure the smoothness of the cleaning disc 2 during rotation, in this embodiment, the upper end face of the overlapping part 52 includes a guide slope 521. The guide slope 521 is inclined downward in the direction close to the cleaning disc 2, so that the first end 21 of the cleaning disc 2 can slide smoothly along the guide slope 521 during the rotation from the first working position to the second working position, avoiding the problems of jamming or excessive frictional resistance.

[0085] It should be noted that the tilt angle of the guide slope 521 is designed according to the rotation trajectory and movement path of the cleaning disc 2 to ensure that when the cleaning disc 2 rotates, the contact between its edge and the overlapping part 52 is gradual rather than abrupt.

[0086] When the cleaning disc 2 is in the first working position, its first end 21 is stably attached to the upper end surface of the overlapping part 52, and the guide slope 521 participates in the sealing at this time; while the cleaning disc 2 is triggered to rotate to the second working position, the first end 21 gradually slides down along the guide slope 521 and eventually leaves the contact area of ​​the overlapping part 52, entering the state of forming the sewage discharge gap d.

[0087] With this configuration, the guide slope 521 not only provides support and guidance, but also effectively reduces the frictional resistance between the cleaning disc 2 and the seal 5, improving the smoothness and response speed of the overall movement.

[0088] Furthermore, in order to ensure that the seal 5 can effectively make way when the cleaning disc 2 rotates and to ensure the smooth rotation of the cleaning disc 2, in this embodiment, the cleaning disc assembly 100 also includes an elastic member 6. The seal 5 is elastically installed on the base 1 through the elastic member 6 so that when the cleaning disc 2 rotates toward the second working position, the seal makes way to form a sewage discharge gap d between it and the cleaning disc 2.

[0089] It should be noted that the elastic element 6 can be a compression spring, torsion spring, or rubber pad, etc., with one end connected to the bottom 10 of the base 1 and the other end acting on the bottom area of ​​the sealing element 5, providing an upward pre-tightening force to the sealing element 5. This arrangement ensures that the sealing element 5 is always in an upward-push-up state when not subjected to external force, thereby stably forming a contact fit with the first end 21 of the cleaning disc 2.

[0090] Specifically, when the cleaning disc 2 is in the first working position, its first end 21 overlaps the upper end face of the overlapping part 52, forming a limiting fit in the vertical direction. At this time, under the action of the elastic member 6, the overlapping part 52 is subjected to an upward pre-tightening force, and the first end 21 of the cleaning disc 2 is pressed tightly by the pre-tightening force.

[0091] When the cleaning disc 2 rotates to the second working position around the rotation axis extending in the first horizontal direction, the cleaning disc 2 tilts, and its first end 21 gradually separates from the initial position and from the overlapping part 52. Because the sealing member 5 is supported by the elastic member 6, it is compressed downwards under the pressure applied by the cleaning disc 2, thereby automatically generating a certain clearance space, forming a sewage discharge gap d between the cleaning disc 2 and the overlapping part 52. Sewage can be smoothly discharged through this gap and finally exited through the second sewage outlet c.

[0092] By setting the elastic element 6, it can cooperate with the overlapping part 52, so that the sealing element 5 can actively adjust and automatically make way when the cleaning plate 2 switches to the second working position, thereby forming a sewage discharge gap d between the two, so that sewage can be discharged smoothly and the risk of residue can be reduced.

[0093] Since the water receiving tray 4 comes into direct contact with sewage containing solid waste, it is prone to dirt accumulation or odor after long-term use. Furthermore, in order to facilitate users or equipment maintenance personnel to clean or replace the water receiving tray 4 that receives sewage regularly, in this embodiment, the water receiving tray 4 is detachably connected to the base 1.

[0094] There are various ways to achieve detachable connection. The water tray 4 can be detachably installed on the bottom 10 of the base 1 or the base station support structure through snap-fit, sliding rail, magnetic or threaded connection. Specifically, the outer periphery of the water tray 4 is provided with a positioning flange or limiting structure, which cooperates with the corresponding groove or limiting slot on the base 1 to realize quick assembly and separation operations, making it convenient for users to remove it regularly for thorough cleaning or to replace the water tray 4 with a new one.

[0095] Preferably, the water tray 4 is made of a corrosion-resistant and easy-to-clean material, such as plastic or stainless steel, and its inner wall is provided with a guide slope or drainage channel to improve liquid discharge efficiency and reduce residue.

[0096] In this embodiment, the base 1 includes a first base body 11 for connection with a base station, and a first drain outlet b is provided on the first base body 11; a cleaning tray is provided on the periphery of the first base body 11, and a water inlet a is provided on the cleaning tray; a rib structure 111 is provided between the cleaning tray and the first base body 11, and the rib structure 111 defines a water inlet channel 2b and a drain channel 11a that are connected. The water inlet channel 2b is formed on the cleaning tray to connect the water inlet a and the cleaning tank 2a, and the drain channel 11a is formed on the first base body 11 to discharge the sewage from the cleaning tank 2a to the first drain outlet b.

[0097] It is understood that a rib structure 111 is provided between the cleaning tray 2 and the first base 11. This rib structure 111 extends from either the first base 11 or the cleaning tray 2, and is preferably located in the top edge region of the first base 11 and extends circumferentially thereafter. When the cleaning tray 2 is installed in place, an isolation space is formed between the rib structure 111 and the bottom surface of the cleaning tray 2, thereby defining two independent and interconnected channels: a water inlet channel 2b and a drain channel 11a.

[0098] The water inlet channel 2b is formed on the outer wall surface of the cleaning pan 2, connected to the water inlet a, and ultimately leads to the cleaning tank 2a, so as to realize the process of external water source entering the cleaning tank 2a; the drainage channel 11a is formed on the outer wall surface of the first base 11, one end of which is connected to the cleaning tank 2a through the space defined by the rib structure 111, and the other end is connected to the first sewage outlet b, which is used to guide the cleaned sewage to the subsequent drainage system inside the base station.

[0099] In this way, the water inlet and drainage paths can be divided and isolated only by the rib structure 111 between the cleaning plate 2 and the first seat 11, without the need for additional complex pipes or seals to complete the flow channel arrangement, thus simplifying the overall structural complexity.

[0100] Furthermore, in this embodiment, the cleaning tray 2 has a first end 21 and a second end 22 located in a second horizontal direction, and the second horizontal direction is intersecting the first horizontal direction; the second end 22 of the cleaning tray 2 is rotatably connected to the base 1, and the cleaning tank 2a is located closer to the first end 21 of the cleaning tray 2 than the second end 22 of the cleaning tray 2.

[0101] It should be noted that the first horizontal direction refers to the direction of the axis around which the cleaning disc 2 rotates, which is a horizontal straight line and is the center line of the rotation of the cleaning disc 2; while the second horizontal direction refers to the direction of the cleaning disc 2 extending from one end to the other, forming a 90° angle with its axis of rotation, constituting the width or length direction of the cleaning disc 2.

[0102] It is understood that the second end 22 of the cleaning disc 2 is fixedly connected to the base 1 via a rotating structure, serving as the fulcrum for the rotation of the entire cleaning disc 2; while the cleaning tank 2a is located closer to the first end 21 of the cleaning disc 2, i.e., on the side away from the fulcrum. This causes the water in the cleaning tank 2a near the first end 21 to generate a larger amplitude of motion and acceleration due to the larger radius of rotation, resulting in a larger displacement amplitude and a higher fluid turbulence velocity, thereby causing solid waste to move and be discharged more quickly with the water flow.

[0103] Therefore, during use, when the cleaning plate 2 switches from the first working position to the second working position, since the cleaning tank 2a is far from the axis of rotation, the centrifugal force and gravity acting on the liquid inside it are more obvious at the same rotation angle, thus generating a stronger flow tendency, which makes it easier to discharge the sewage containing solid waste in the cleaning tank 2a more effectively and reduce residue.

[0104] This utility model also proposes a cleaning equipment base station, which includes a clean water tank, a wastewater tank, and a cleaning tray assembly 100. The specific structure of the cleaning equipment base station is as described in the above embodiments. Since the cleaning tray assembly 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0105] This utility model also proposes a cleaning system, wherein the cleaning equipment can be a vacuum cleaner, a robotic vacuum cleaner, or a vacuum and mop combo, etc. The cleaning system includes a cleaning device and a cleaning device base station. The specific structure of the cleaning system is as described in the above embodiments. Since this cleaning device base station adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0106] Specifically, in some embodiments, the cleaning system further includes a cleaning device, which includes a cleaning component that is movable in the vertical direction to be movably disposed in the direction of approaching and moving away from the cleaning tank 2a. When the roller moves downward, it drives the cleaning disc 2 to move from a first working position to a second working position.

[0107] It should be noted that the cleaning equipment is located near the base station or is movably connected to the base station. It includes a cleaning component that is movably installed in the vertical direction and can reciprocate in directions close to and away from the cleaning tank 2a. The cleaning component may include a roller, a mop assembly, a rotating brush roller, or a composite cleaning module. The following description uses a cleaning component including a roller as an example.

[0108] Specifically, after completing the ground cleaning task, the roller in the cleaning assembly returns to the base station and enters the cleaning tank 2a for rinsing; then, under the command of the control system, the roller moves downward and applies pressure to the cleaning disc 2 in the vertical direction.

[0109] As the roller moves downward, its bottom edge or dedicated pressing structure contacts the first end 21 area of ​​the cleaning disc 2 and applies a downward force to it. Since the cleaning disc 2 is rotatably connected to the base 1 about a rotation axis extending in the first horizontal direction, and its second end 22 is the pivot point, the cleaning disc 2 begins to rotate from the first working position to the second working position under the continuous downward pressure of the roller.

[0110] At this point, the cleaning tank 2a tilts, and the residual sewage in the tank flows due to gravity, carrying solid waste out of the cleaning tank 2a. This process requires no additional drive mechanism; the up-and-down movement of the roller itself triggers the switching of the cleaning disc 2, achieving automatic sewage discharge.

[0111] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
