Description

Technical Field

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

[0002] With the development of social productivity, people's living standards have also improved. With their material needs met, people have begun to use various tools to reduce labor and improve their quality of life, leading to the emergence of household cleaning equipment. Taking a robot vacuum and mop as an example, after completing its cleaning work, it needs to enter a cleaning station for maintenance (such as charging, dust collection, wastewater discharge, and self-cleaning).

[0003] The dust collection chamber of a base station is used to temporarily store dry dust. Under normal use, water typically does not enter the chamber, therefore, in existing technology, a drainage structure is not included. However, in actual use, the cleaning equipment may suck in liquid waste into the dust box, or moisture may seep into the dust collection chamber due to improper user operation or damage to base station components (water tank seal failure, pipe rupture, etc.). Since there is no drainage path in the dust collection chamber, water will stagnate for a long time, leading to mold growth and unpleasant odors, as well as dust adhesion and blockage, reducing dust collection efficiency. The accumulated water may also leak from the gaps in the dust collection chamber and drip onto the surface of the cleaning equipment below, making the equipment dirty and reducing the user experience.

[0004] This disclosure provides a cleaning system to address the problems existing in the prior art.

[0013] In one embodiment of this disclosure, an elastic element is also included, and the transmission segment is configured to have a tendency to drive the triggering mechanism to move toward the second position under the action of the elastic element.

[0014] In one embodiment of this disclosure, the cleaning base station further includes a receiving cavity for docking the cleaning equipment, the receiving cavity opening to the front and having at least a rear wall surface; the functional segment extends at least partially forward into the receiving cavity, and the sewage discharge channel is configured to be located on the rear wall surface.

[0015] In one embodiment of this disclosure, a docking portion is provided on the receiving cavity, and the water outlet is provided at the bottom end of the docking portion. The top end of the docking portion is connected to the dust collection cavity through a flexible hose. The water passage inside the flexible hose and the water passage inside the docking portion together constitute the sewage discharge channel.

[0016] In one embodiment of this disclosure, a cleaning tank is provided at the bottom of the cleaning base station; the outlet of the sewage discharge channel is located above the cleaning tank; when the sewage discharge channel is open, the liquid in the dust collection chamber is configured to flow into the cleaning tank under the action of gravity.

[0017] In one embodiment of this disclosure, when the cleaning device is docked at the cleaning base station, the vertical projection of the cleaning device and the water outlet does not overlap.

[0018] In one embodiment of this disclosure, the bottom surface of the inner wall of the dust collection chamber is constructed as an inclined surface, and the connection between the sewage discharge channel and the dust collection chamber is located on the relatively lower side of the inclined surface.

[0019] According to a second aspect of this disclosure, a cleaning system is also provided, comprising: Cleaning equipment used to clean the work surface; A cleaning base station is used to dock the cleaning equipment; the cleaning base station includes a dust collection chamber, a sewage discharge channel communicating with the dust collection chamber, and a triggering mechanism; During dust collection operations, the triggering mechanism seals the outlet of the sewage discharge channel; When not performing dust collection operations, or when the cleaning equipment is parked, the triggering mechanism is allowed to open the outlet of the sewage discharge channel so that the liquid in the dust collection chamber can be discharged through the sewage discharge channel.

[0020] According to a third aspect of this disclosure, a cleaning system is also provided, comprising: Cleaning equipment used to clean the work surface; A cleaning base station includes a receiving cavity for docking the cleaning equipment, a dust collection cavity, and a sewage discharge channel communicating with the dust collection cavity; a cleaning tank is provided at the bottom of the receiving cavity, and the outlet of the sewage discharge channel is located above the cleaning tank; Specifically, when the cleaning equipment docks at the cleaning base station, the vertical projections of the cleaning equipment and the water outlet do not overlap.

[0021] According to a fourth aspect of this disclosure, a cleaning system is also provided, comprising: Cleaning equipment used to clean the work surface; A cleaning base station is used to dock the cleaning equipment; the cleaning base station includes a dust collection chamber, a sewage discharge channel communicating with the dust collection chamber, and a triggering mechanism, which can move between a first position and a second position; When the cleaning equipment is parked at the cleaning base station and the triggering mechanism is in the first position, the triggering mechanism seals the outlet of the sewage discharge channel; When the triggering mechanism is in the second position, the triggering mechanism is disengaged from the outlet of the sewage discharge channel, and the liquid in the dust collection chamber can be discharged through the sewage discharge channel.

[0022] One beneficial effect of this disclosure is that by setting up a drainage channel connected to the dust collection chamber in the cleaning base station, a path for draining the dust collection chamber is formed, and the liquid in the dust collection chamber can be discharged. This avoids water accumulation in the dust collection chamber, which can lead to the growth of mold and produce odors, and also avoids dust adhesion and blockage. Water accumulation in the dust collection chamber will not drip onto the surface of the cleaning equipment below, and the cleaning equipment can be kept clean, thereby improving the user experience.

[0023] Furthermore, this disclosure achieves multi-functional coordination of sewage tank discharge, cleaning equipment dust collection, and dust collection chamber drainage by reusing the trigger mechanism. Specifically, when the trigger mechanism moves to the first position, it opens the sewage outlet, allowing the dirt in the sewage tank to be discharged into the cleaning base station; simultaneously, the trigger mechanism also seals the outlet of the sewage discharge channel, thereby ensuring that the dust collection chamber is sealed, allowing the cleaning base station to perform dust collection normally and preventing negative pressure leakage that could reduce dust collection efficiency. This allows the cleaning system to simultaneously discharge sewage and collect dust, improving the dirt collection efficiency of the cleaning base station. This disclosure eliminates the need for separate components for opening the sewage outlet and sealing the sewage discharge channel; instead, it achieves dual functions through a single trigger mechanism, thereby simplifying the structural design of the cleaning base station and reducing system costs and failure risks.

[0028] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0029] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0032] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0033] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0034] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0035] After completing their cleaning tasks, the cleaning equipment needs to be moved into the cleaning base station for maintenance, including charging, dust collection, wastewater drainage, and self-cleaning. The dust collection chamber of the cleaning base station temporarily stores dust from the cleaning equipment. During actual use, the cleaning equipment may suck in liquid waste into the dust box, or moisture may seep into the dust collection chamber due to improper user operation or damage to base station components. Since there is no drainage path in the dust collection chamber, water will stagnate for a long time, leading to mold growth and unpleasant odors, as well as dust accumulation and blockages, reducing dust collection efficiency. Water may also leak from the gaps in the dust collection chamber and drip onto the surface of the cleaning equipment below, making it dirty and reducing the user experience.

[0036] To solve the above problems, refer to Figure 2 This disclosure provides a cleaning system, including a cleaning base station 1 and a cleaning device 2. The cleaning device 2 can be a handheld cleaning machine well-known to those skilled in the art, such as a handheld cleaner, handheld vacuum cleaner, handheld floor scrubber, or handheld fabric cleaner; or it can be a self-moving cleaning robot well-known to those skilled in the art, such as a robotic vacuum cleaner or a robotic vacuum and mop combo. This embodiment uses a robotic vacuum and mop combo as an example for illustration.

[0037] The cleaning device 2 is used to clean the work surface. Specifically, the cleaning device 2 may be equipped with a traveling mechanism that can rotate under its own driving force, allowing the cleaning device 2 to move freely across the work surface and clean the entire work surface of the house. The cleaning device 2 may be equipped with a suction port and a dust box connected to the suction port. The suction port can suck in small particulate solid dirt such as dust and hair from the work surface for temporary storage. In one embodiment of this disclosure, the cleaning device 2 is also equipped with a cleaning component for cleaning the work surface. The cleaning component can be a mop tray, roller, or roller brush, etc., and its surface can be wetted and contact the work surface to be cleaned, thereby completing the mopping cleaning work. In the traveling direction of the cleaning device 2, the suction port can be located in front of the cleaning component, thus realizing the work sequence of vacuuming first and then mopping.

[0038] refer to Figure 10 The cleaning equipment 2 includes a wastewater tank 21, which is used to temporarily store dirt and grime, including garbage sucked up from the work surface and wastewater generated during the cleaning process. The wastewater tank 21 has a wastewater outlet with an openable wastewater valve 22. When the wastewater valve 22 is open, the dirt temporarily stored in the wastewater tank 21 will flow out from the wastewater outlet under gravity. It is understood that when the cleaning equipment 2 is performing normal cleaning work, the wastewater valve 22 remains closed to prevent dirt and grime from flowing out of the wastewater tank 21 and contaminating the work surface; the wastewater valve 22 will only briefly open to discharge dirt when the equipment is docked at the cleaning base station 1 and the cleaning system controls the discharge procedure. refer to Figure 1 and Figure 2 The cleaning base station 1 is used to dock the cleaning equipment 2. For example, after the cleaning equipment 2 has finished cleaning the work surface, it can drive into the cleaning base station 1 and dock there. This allows the cleaning base station 1 to perform dust collection, sewage discharge, self-cleaning, charging, and replenishment of cleaning fluid for the cleaning equipment 2 docked there, so that it can be used by the user next time.

[0039] In one embodiment of this disclosure, reference is made to Figure 1 and Figure 8 The cleaning base station 1 includes a receiving cavity 11 for docking the cleaning equipment 2, the receiving cavity 11 opening to the front and having at least a rear wall surface. Figure 8 As shown, the X1 direction is the front side, and the X2 direction is the rear side. In the horizontal plane, the Y1 and Y2 directions, perpendicular to the front and rear directions, are the left and right sides, respectively. The receiving cavity 11 is located in the bottom area of ​​the clean base station 1, as shown... Figure 1 As shown, a driving ramp 18 extending forward to the external working surface is provided at the bottom of the receiving cavity 11. The cleaning equipment 2 can automatically drive into the receiving cavity 11 through the driving ramp 18, thereby docking with the cleaning base station 1.

[0040] refer to Figure 3 and Figure 8 The cleaning base station 1 includes a dust collection chamber 12. Specifically, the cleaning base station 1 may include a body 10, on which a receiving cavity 11 and a dust collection chamber 12 are provided, wherein the receiving cavity 11 is located below the dust collection chamber 12. When the cleaning equipment 2 is docked in the cleaning base station 1, the dust collection chamber 12 can dock with the dust box of the cleaning equipment 2 to clean the dust, debris and other garbage collected by the cleaning equipment 2 during operation.

[0041] In one embodiment of this disclosure, reference is made to Figure 3 The cleaning base station 1 is equipped with a fan 101, and a negative pressure port 123 communicating with the fan 101 can be opened on the wall of the dust collection chamber 12. During dust collection, the fan 101 can draw air from the dust collection chamber 12 through the negative pressure port 123, thereby creating a negative pressure environment in the dust collection chamber 12, which draws the garbage in the dust box of the cleaning equipment 2 into the dust collection chamber 12. Furthermore, a removable and replaceable dust bag can be installed in the dust collection chamber 12. The dust bag is connected to the dust box, so that during dust collection, the garbage is directly sucked into the dust bag and does not fall into the inner wall of the dust collection chamber 12. When the dust bag is full, the user can directly replace it with a new dust bag without having to manually clean the dust collection chamber 12, thus facilitating the user's cleaning and maintenance of the cleaning base station 1.

[0042] refer to Figures 4 to 7 The cleaning base station 1 includes a sewage discharge channel 13 connected to the dust collection chamber 12. A trigger mechanism 14 is provided on the body 10, which can move relative to the body 10 between a first position and a second position. When the cleaning device 2 stops at the cleaning base station 1 and the trigger mechanism 14 is in the first position, the trigger mechanism 14 abuts against the sewage valve 22 and opens the sewage outlet, while the trigger mechanism 14 seals the outlet 130 of the sewage discharge channel 13. When the trigger mechanism 14 is in the second position, the trigger mechanism 14 is configured to disengage from the sewage valve 22 to close the sewage outlet, and the trigger mechanism 14 is disengaged from the outlet 130 of the sewage discharge channel 13, allowing the liquid in the dust collection chamber 12 to be discharged through the sewage discharge channel 13.

[0043] Specifically, the sewage discharge channel 13 is used to drain the water accumulated in the dust collection chamber 12. One end of the sewage discharge channel 13 is connected to the dust collection chamber 12, and the other end can extend to the wastewater collection area outside the cleaning base station 1. When the sewage discharge channel 13 is open (i.e. when the triggering mechanism 14 is in the second position), the liquid in the dust collection chamber 12 can be discharged, thereby preventing the accumulation of water in the dust collection chamber 12 from causing mold growth and odor, and preventing dust from sticking and causing blockage. The water accumulated in the dust collection chamber 12 will not drip onto the surface of the cleaning device 2 below, and the cleaning device 2 can be kept clean, thereby improving the user experience.

[0044] Furthermore, this disclosure achieves multi-functional coordination of sewage discharge from the sewage tank 21, dust collection from the cleaning equipment 2, and drainage from the dust collection chamber 12 by reusing the trigger mechanism 14. Specifically, when the trigger mechanism 14 moves to the first position, it abuts against the sewage valve 22 and opens the sewage outlet, allowing the dirt in the sewage tank 21 to be discharged into the cleaning base station 1; at the same time, the trigger mechanism 14 can also seal the outlet 130 of the sewage discharge channel 13, thereby ensuring that the dust collection chamber 12 is in a sealed state, and the cleaning base station 1 can perform dust collection work normally, avoiding negative pressure leakage that would reduce dust collection efficiency; thus, the cleaning system can simultaneously discharge sewage and collect dust, improving the dirt collection efficiency of the cleaning base station 1. This disclosure eliminates the need for separate components for opening the sewage valve 22 and sealing the sewage discharge channel 13, but achieves dual functions through a single trigger mechanism 14, thereby simplifying the structural design of the cleaning base station 1 and reducing system costs and failure risks.

[0045] In one embodiment of this disclosure, reference is made to Figure 5 and Figure 7 The trigger mechanism 14 is hinged to the body 10 and rotatably connected to the body 10 via a hinge shaft 140, allowing it to switch between a first position and a second position during rotation. Specifically, the trigger mechanism 14 includes a functional section 141 and a transmission section 142 located on either side of the hinge point. The functional section 141 performs the functions of opening and closing the sewage outlet and the water outlet 130, while the transmission section 142 receives power to drive the trigger mechanism 14 to rotate as a whole. This segmented design ensures that the power input and functional output of the trigger mechanism 14 do not interfere with each other. Specifically, the functional section 141 extends at least partially forward into the receiving cavity 11, thereby acting close to the sewage outlet, reducing the travel distance of the functional section 141, and improving operational efficiency.

[0046] During the rotation of the trigger mechanism 14 from the second position to the first position, the functional section 141 is configured to rise upwards to abut against the sewage valve 22, thereby opening the sewage outlet and simultaneously sealing the outlet 130 of the sewage discharge channel 13. Specifically, the trigger mechanism 14 can remain in the second position without external force, at which time the sewage valve 22 remains closed and the outlet 130 of the sewage discharge channel 13 remains open; when the trigger mechanism 14 rotates from the second position to the first position, the functional section 141 rises upwards along the rotation trajectory, and this rising action simultaneously opens the sewage outlet of the sewage tank 21 of the cleaning equipment 2 and seals the outlet 130 of the sewage discharge channel 13.

[0047] This disclosure employs a hinge shaft 140 to rotatably mount the trigger mechanism 14, thereby providing a fulcrum for the trigger mechanism 14's rotation and limiting its movement trajectory. This prevents jamming caused by deviations in the direction of movement, ensuring continuous upward lifting of the functional section 141 and high movement stability. Furthermore, during the upward lifting of the functional section 141, the opening of the sewage outlet and the sealing of the sewage discharge channel 13 can be achieved simultaneously. Both functions are triggered by the lifting action, thus ensuring their synchronicity and preventing negative pressure leakage in the dust collection chamber 12 or untimely sewage discharge due to sequential actions.

[0048] In one embodiment of this disclosure, reference is made to Figure 7 A sealing element 133 is provided at the outlet 130 of the sewage discharge channel 13. When in the first position, the top end face of the functional section 141 is configured to abut against the sealing element 133 to seal the outlet 130 of the sewage discharge channel 13. Specifically, the sealing element 133 can be a soft rubber pad located below the outlet 130 of the sewage discharge channel 13. When the functional section 141 of the triggering mechanism 14 is raised to abut against the sealing element 133, the sealing element 133 can undergo slight deformation, thereby filling the gap between the functional section 141 and the outlet 130 of the sewage discharge channel 13, thereby improving the sealing effect, preventing air leakage in the dust collection chamber 12 when maintaining negative pressure dust collection, and ensuring stable dust collection function. Even if there is a slight deviation in the rotation angle of the triggering mechanism 14, effective sealing can be achieved through deformation compensation of the sealing element 133, thereby reducing the precision requirements during the assembly of the cleaning base station 1. In addition, the flexible seal 133 can buffer the direct rigid contact between the functional section 141 and the outlet 130, avoiding wear on the top end face of the functional section 141 or deformation of the outlet 130 of the sewage channel 13 caused by long-term contact, thereby extending the service life of the triggering mechanism 14 and the sewage channel 13.

[0049] In one specific embodiment of this disclosure, reference is made to Figure 5 The seal 133 is configured to form a flared structure below the outlet 130 of the drain channel 13. In the first position, the top end face of the functional section 141 is configured to abut against the inner surface of the flared structure. Specifically, the diameter of the seal 133 gradually increases outward from top to bottom. The flared structure increases the contact area between the seal 133 and the top end face of the functional section 141, thereby improving the sealing effect. In addition, the flared structure is located below the outlet 130. When the drain channel 13 is open, residual liquid in the dust collection chamber 12 is discharged through the drain channel 13. The liquid can flow smoothly along the inner surface of the flared structure, preventing liquid from remaining at the connection between the seal 133 and the outlet 130, and reducing the risk of bacterial growth.

[0050] In one embodiment of this disclosure, reference is made to Figure 7 and Figure 11The functional segment 141 has a protrusion 1411 at its end away from the hinge point. When in the first position, the protrusion 1411 is configured to cooperate with the sewage valve 22 to open the sewage outlet. Specifically, the protrusion 1411 can be integrally formed at the end of the functional segment 141. When the triggering mechanism 14 rotates to the first position, the protrusion 1411 cooperates with the sewage valve 22 of the cleaning device 2. It should be noted that the sewage valve 22 is usually in a normally closed state (e.g., kept closed by elastic force or its own weight to prevent liquid leakage when the sewage tank 21 is not drained). The outer surface of the sewage valve 22 can be provided with a force-bearing part for cooperating with the protrusion. As the triggering mechanism 14 continues to rotate to the first position, the protrusion 1411 contacts the force-bearing part of the sewage valve 22 and gradually applies a pushing force. This pushing force can overcome the closing force of the sewage valve 22, thereby causing the sealing structure in the sewage valve 22 to move away from the sewage outlet. When the triggering mechanism 14 reaches the first position, the pushing stroke of the protrusion 1411 reaches the preset value, the sewage valve 22 is fully opened, the sewage outlet is in the open state, and the dirt in the sewage tank 21 is discharged through the sewage outlet under the action of gravity, realizing the sewage discharge action of the cleaning equipment 2.

[0051] This disclosure provides a protrusion 1411 on the functional section 141, which can precisely act on the sewage valve 22, thereby applying force to the sealing structure of the sewage outlet and preventing the functional section 141 from accidentally contacting other parts of the sewage tank 21. Furthermore, based on the lever principle, by placing the protrusion 1411 at the end of the functional section 141, the required force is reduced, and a smaller driving force is needed to open the sewage valve 22, improving opening reliability.

[0052] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 5 and Figure 7 The cleaning base station 1 also includes a drive mechanism 15, and a trigger mechanism 14 is configured to move relative to the body 10 between a first position and a second position under the drive of the drive mechanism 15; a transmission section 142 is driven by the drive mechanism 15. Specifically, the movement of the trigger mechanism 14 is powered by the drive mechanism 15, and the power of the drive mechanism 15 is transmitted to the transmission section 142 through the transmission section, thereby driving the trigger mechanism 14 to move between the first position and the second position. When a sewage discharge or dust collection procedure needs to be executed, the drive mechanism 15 drives the trigger mechanism 14 to switch to the first position based on a sewage discharge signal; after the sewage discharge or dust collection is completed, the drive mechanism 15 drives the trigger mechanism 14 to switch back to the second position based on an end signal. This disclosure realizes automated switching of the trigger mechanism 14 position without manual intervention by the user, improving ease of use.

[0053] In this embodiment, the triggering mechanism 14 is generally L-shaped, with the transmission section 142 and the functional section 141 arranged approximately perpendicularly, and the hinge shaft 140 located at the bending inflection point. This makes the movement trajectories of the transmission section 142 and the functional section 141 independent, forming two independent lever arms. The approximately perpendicularly arranged lever arms can efficiently convert the driving force into the lifting force of the functional section 141, reducing power loss. In addition, the L-shaped triggering structure is adapted to the spatial layout of the base station, effectively utilizing the corner space inside the clean base station 1, eliminating the need for additional transmission components for steering, and reducing structural complexity.

[0054] In one specific embodiment of this disclosure, reference is made to Figure 5 and Figure 7 The transmission part is a cam 151 connected to the output end of the drive mechanism 15. The cam 151 abuts against the transmission section 142. When the drive mechanism 15 drives the cam 151 to rotate in the first direction, the cam 151 pushes the trigger mechanism 14 to move to the first position. When the drive mechanism 15 drives the cam 151 to rotate in the second direction, the trigger mechanism 14 moves to the second position. The cam 151 has a protruding part with a large diameter. When the cam 151 rotates in the first direction, the protruding part can rotate to abut against the transmission section 142 and push the transmission section 142 during continued rotation, so that the trigger mechanism 14 moves to the first position. When the cam 151 rotates in the second direction opposite to the first direction, the pushing force of the protruding part on the transmission section 142 is gradually removed, and the trigger mechanism 14 can return to the second position.

[0055] Furthermore, such as Figure 5 As shown, an elastic element 16 is also provided in the cleaning base station 1. The transmission section 142 is configured to tend to drive the trigger mechanism 14 to move to the second position under the action of the elastic element 16. Specifically, the elastic element 16 can be a spring pre-compressed between the transmission section 142 and the body 10, and the spring can apply an elastic force to the transmission section 142. During the rotation of the cam 151 in the first direction, the trigger mechanism 14 rotates to the first position, causing the elastic element 16 to gradually compress; when the cam 151 rotates in the second direction, the thrust of the cam 151 on the transmission section 142 is removed, and the trigger mechanism 14 can be reset to the second position under the elastic force of the elastic element 16. This ensures that the trigger mechanism 14 will not get stuck in the first position, but can automatically reset to the second position after the sewage discharge and dust collection procedures are completed, thereby opening the outlet 130 of the sewage discharge channel 13 in time to discharge the liquid in the dust collection chamber 12.

[0056] In one embodiment of this disclosure, the sewage discharge channel 13 is configured to be located on the rear wall. The front side of the cleaning base station 1 is used to open the receiving cavity 11, reserve operating space, and set up charging interfaces, etc., the middle part is used to install the fan 101, circuit board, etc., while the rear side is relatively empty. This disclosure sets the sewage discharge channel 13 on the rear wall of the receiving cavity 11, that is, in the rear space of the cleaning base station 1, thereby making full use of the rear space of the cleaning base station 1, avoiding layout conflicts between the sewage discharge channel 13 and other core components, and shortening the connection distance between the sewage discharge channel 13 and the dust collection chamber 12, and shortening the length of the sewage discharge channel 13 to reduce liquid flow resistance.

[0057] like Figure 5 As shown, a docking part 132 is provided on the receiving cavity 11, and a water outlet 130 is provided at the bottom end of the docking part 132. Specifically, the docking part 132 is fixed in position relative to the receiving cavity 11 and can be directly installed on the body 10 of the cleaning base station 1, thereby ensuring that the docking part 132, the body 10, and the receiving cavity 11 form a stable positional relationship. This helps to ensure positioning accuracy, and the relative position of the water outlet 130 and the triggering mechanism 14 remains stable and will not shift due to factors such as vibration of the cleaning base station 1 or impact of the cleaning equipment 2 stopping. This ensures that when the triggering mechanism 14 moves to the first position, the functional section 141 can accurately seal the water outlet 130, avoiding negative pressure leakage that would reduce dust collection efficiency.

[0058] The top of the docking part 132 is connected to the dust collection chamber 12 via a flexible hose 131. The water channels inside the flexible hose 131 and the docking part 132 together form the sewage discharge channel 13. A water channel is formed throughout the docking part 132, allowing liquid from the dust collection chamber 12 to be discharged through the water channels in the flexible hose 131, the docking part 132, and the outlet 130. The flexible hose 131 is flexible, allowing its direction to be adjusted according to the position of other components inside the base station, facilitating internal structural optimization and improving the layout flexibility of the sewage discharge channel 13. Furthermore, the docking part 132 is fixed to the body 10. During assembly, it only needs to be precisely positioned and fixed to the body 10 and the receiving cavity 11, and then connected to the dust collection chamber 12 via the flexible hose 131. This eliminates the need for complex rigid pipe splicing and calibration of the entire sewage discharge channel 13, reducing assembly difficulty and labor costs. During later maintenance, the flexible hose 131 or the bracket can be disassembled separately without disassembling and cleaning other components of the base station 1, further reducing maintenance difficulty and costs.

[0059] In one embodiment of this disclosure, reference is made to Figure 3The cleaning base station 1 has a cleaning tank 17 at its bottom. When the cleaning equipment 2 is in place, its cleaning components (such as roller brushes, wiping cloth trays, etc.) can be located in the cleaning tank 17, where they can self-clean. The cleaning tank 17 can collect wastewater generated during the self-cleaning process and dripping cleaning liquid. The sewage discharge channel 13 is connected to the cleaning tank 17 to discharge liquid from the dust collection chamber 12. This disclosure reuses the cleaning tank 17 at the bottom of the receiving cavity 11 as the drainage terminal of the sewage discharge channel 13, thus eliminating the need to design a separate drain outlet or wastewater collection box for the dust collection chamber 12, thereby simplifying the overall structure of the cleaning base station 1. The water accumulated in the dust collection chamber 12 and the cleaning wastewater from the cleaning components can be discharged centrally through the same cleaning tank 17. Users only need to clean the cleaning tank 17 periodically to maintain the hygiene of the cleaning base station 1, improving ease of use.

[0060] Furthermore, the outlet 130 of the sewage discharge channel 13 is located above the cleaning tank 17. When the sewage discharge channel 13 is open, the liquid in the dust collection chamber 12 is configured to flow into the cleaning tank 17 under gravity. When the trigger mechanism 14 is in the second position, the outlet 130 is unobstructed below, allowing the liquid in the sewage discharge channel 13 to flow out naturally under gravity. The liquid flows naturally into the cleaning tank 17 by gravity, eliminating the need for power components such as water pumps, thus reducing production and maintenance costs.

[0061] In one embodiment of this disclosure, reference is made to Figure 8 and Figure 9 The bottom surface of the inner wall of the dust collection chamber 12 is constructed as an inclined surface 121, and the connection port 124 between the sewage discharge channel 13 and the dust collection chamber 12 is located on the relatively lower side of the inclined surface 121. Specifically, the inclined direction of the inclined surface 121 can be from the periphery of the dust collection chamber 12 towards the center or one side. In this embodiment, the connection port 124 is located at the right rear (X2-Y2) of the dust collection chamber 12. The inclined surface 121 gradually decreases in the Y2 direction and gradually decreases in the X2 direction. The inclination angle of the inclined surface 121 is about 5-10°. The gentle inclination angle will not affect the overall spatial layout and capacity of the dust collection chamber 12, and can also guide the flow of liquid. The inclined surface 121 can guide the liquid in the dust collection chamber 12 to flow towards the lower connection port 124, thereby avoiding the formation of local stagnation of liquid on the bottom surface of the dust collection chamber 12. Especially for a small amount of liquid, the inclined surface 121 can improve the efficiency of liquid discharge, ensuring that the liquid can flow into the connection port 124 under the action of gravity and be discharged through the sewage discharge channel 13.

[0062] In one embodiment of this disclosure, such as Figure 8As shown, multiple guide ribs 122 are provided on the inclined surface 121. The guide ribs 122 are configured to guide the liquid in the dust collection chamber 12 to the connecting port 124. Specifically, multiple guide ribs 122 are integrally formed on the inclined surface 121 of the dust collection chamber 12. The multiple guide ribs 122 are spaced apart and configured to extend from front to back, thereby forming multiple paths for guiding the liquid in the dust collection chamber 12 to the rear side of the dust collection chamber 12. Under the guidance of the inclined surface 121, the liquid flows to the connecting port 124. The flow paths formed by the guide ribs 122 can further optimize the liquid flow path in the dust collection chamber 12, avoid the liquid from spreading randomly on the inclined surface 121 (such as the liquid easily spreading irregularly on a plane due to surface tension), ensure that the liquid flows quickly to the connecting port 124 along the preset path, and improve drainage efficiency.

[0063] In one embodiment of this disclosure, such as Figure 9 As shown, a filter element 134 is installed at the connection port 124 between the sewage discharge channel 13 and the dust collection chamber 12. Specifically, the filter element 134 is used to filter solid dirt. The filter element 134 can be a filter screen, filter cotton, or other structures, which can block impurities such as dust, debris, and hair, while not affecting the passage of liquid. The filter element 134 can prevent impurities from accumulating and clogging in the sewage discharge channel 13, thereby ensuring that the sewage discharge channel 13 remains unobstructed for a long time. The filter element 134 is installed at the connection port 124 between the sewage discharge channel 13 and the dust collection chamber 12, and the edge of the filter element 134 is tightly fitted to the inner wall of the connection port 124, thereby preventing impurities from entering the sewage discharge channel 13 through the gap between the filter element 134 and the connection port 124.

[0064] In one embodiment of this disclosure, when the cleaning device 2 is docked at the cleaning base station 1, the vertical projections of the cleaning device 2 and the water outlet 130 do not overlap. The liquid discharged from the water outlet 130 can fall vertically into the cleaning tank 17, thereby preventing liquid from dripping onto the surface of the cleaning device 2. This prevents watermarks from remaining on the surface of the cleaning device 2, improving the user experience. Furthermore, by positioning the water outlet 130 at a position offset from the cleaning device 2, there is no need for additional liquid-blocking structures such as baffles or guide vanes, simplifying the structural design of the cleaning base station 1.

[0065] In one embodiment of this disclosure, reference is made to Figure 11When the cleaning device 2 docks at the cleaning base station 1, the wastewater outlet is configured to face the cleaning tank 17. When the trigger mechanism 14 opens the wastewater outlet, the liquid in the wastewater tank 21 flows into the cleaning tank 17. The wastewater outlet directly faces the cleaning tank 17, thus shortening the wastewater discharge path and achieving efficient wastewater discharge under gravity. Furthermore, the wastewater in the wastewater tank 21 and the liquid in the dust collection chamber 12 both flow into the cleaning tank 17 for collection. This eliminates the need for multiple liquid collection structures on the cleaning base station 1, simplifying its structural design. Users only need to clean the cleaning tank 17 periodically to maintain the hygiene of the cleaning base station 1, improving ease of use.

[0066] This disclosure also provides a cleaning system, including a cleaning device 2 and a cleaning base station 1. The cleaning device 2 is used to clean the work surface. The cleaning base station 1 is used to dock the cleaning device 2. The cleaning base station 1 includes a body 10, a dust collection chamber 12, and a sewage discharge channel 13 communicating with the dust collection chamber 12. A triggering mechanism 14 is movably disposed on the body 10. During dust collection operations, the triggering mechanism 14 seals the outlet 130 of the sewage discharge channel 13; during non-dust collection operations, or when the cleaning device 2 is not docked, the triggering mechanism 14 is allowed to open the outlet 130 of the sewage discharge channel 13, so that the liquid in the dust collection chamber 12 can be discharged through the sewage discharge channel 13.

[0067] This disclosure can control the movement position of the trigger mechanism 14 based on the dust collection program set in the cleaning base station 1: when dust collection is performed, the trigger mechanism 14 needs to be controlled to move to the first position to seal the outlet 130 of the sewage discharge channel 13, thereby ensuring that the dust collection chamber 12 is in a sealed state, and the cleaning base station 1 can perform dust collection work normally, avoiding negative pressure leakage that would reduce the dust collection efficiency.

[0068] In one embodiment of this disclosure, during the dust collection process, the cleaning device 2 can simultaneously discharge wastewater to the cleaning base station 1. The wastewater discharge process is very rapid (about 1 second), but dust collection usually takes a relatively long time (about 10 seconds). Therefore, the wastewater tank 21 must be empty by the time dust collection is complete. Thus, in this embodiment, the signal indicating that the fan 101 is off can be used as the end signal for wastewater discharge. The drive mechanism 15 can control the trigger mechanism 14 to reset to the second position based on the fan 101 off signal. At this time, the wastewater discharge channel 13 is open, forming a path for drainage from the dust collection chamber 12. The liquid in the dust collection chamber 12 can be discharged, thereby preventing water accumulation in the dust collection chamber 12, which could lead to mold growth and odor, and preventing dust buildup and blockage. Water in the dust collection chamber 12 will not drip onto the surface of the cleaning device 2 below, keeping the cleaning device 2 clean and improving the user experience.

[0069] This disclosure also provides a cleaning system, including a cleaning device 2 and a cleaning base station 1. The cleaning device 2 is used to clean a work surface; the cleaning base station 1 includes a receiving cavity 11 for docking the cleaning device 2, a dust collection cavity 12 located above the receiving cavity 11, and a sewage discharge channel 13 communicating with the dust collection cavity 12. A cleaning tank 17 is provided at the bottom of the receiving cavity 11, and the outlet 130 of the sewage discharge channel 13 is located above the cleaning tank 17, wherein when the cleaning device 2 is docked at the cleaning base station 1, the vertical projections of the cleaning device 2 and the outlet 130 do not overlap.

[0070] This disclosure establishes a drainage channel 13 connected to the dust collection chamber 12 within the cleaning base station 1, thereby creating a path for drainage from the dust collection chamber 12. This allows liquid within the dust collection chamber 12 to drain out, preventing water accumulation that could lead to mold growth and odor, and also preventing dust buildup and blockage. Furthermore, the liquid discharged from the outlet 130 falls vertically into the cleaning tank 17. By positioning the outlet 130 at a position offset from the cleaning device 2, liquid dripping from the outlet 130 onto the surface of the cleaning device 2 is prevented, keeping the cleaning device 2 clean and improving the user experience.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
