[0002] A robotic vacuum cleaner is a type of smart home appliance that uses artificial intelligence to automatically clean floors in a room. The automatic water supply and drainage module is a crucial component for this function, and is often installed as an optional accessory within the main unit. When the robotic vacuum cleaner returns to the base station, it draws water from the clean water tank of the automatic water supply and drainage module through a pipe; simultaneously, it transfers wastewater from inside the robot to the wastewater tank of the same module, thus achieving automatic cleaning.

[0003] During use, the dirt, garbage, and debris collected by the robot vacuum cleaner will enter the wastewater tank of the automatic water supply and drainage module. In order to ensure that large particles of garbage and debris do not clog the pipes, a dirt collection and filtration device is generally required to filter the corresponding garbage and debris.

[0004] However, in the existing technology, the automatic water supply and drainage module is not easy to disassemble after being installed inside the base station. Therefore, the filter module installed in the sewage tank is difficult to remove quickly for cleaning, which will greatly affect the sewage collection efficiency of the sewage tank.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0035] To address the technical problem in existing automatic water supply and drainage modules where the filter module is difficult to disassemble and assemble quickly, affecting the cleaning of the filter module and consequently significantly impacting the wastewater collection efficiency, this application provides a wastewater collection and filtration device and an automatic water supply and drainage module. This device effectively filters large particles of debris and residue in wastewater while facilitating the disassembly of the filter screen, making it easy to remove the filter screen and clean the debris and residue inside.

[0036] Please see Figure 1 , Figure 2 The present application provides a sludge collection and filtration device, including a sludge collection tank 11 and a filter screen 2. The sludge collection tank 11 is located at the top edge of the sewage tank 1. A sludge collection port is provided on one side wall of the sludge collection tank 11. Slots 111 are provided on both sides of the sludge collection port. The filter screen 2 is movably inserted into the slots 111. The opening of the filter screen 2 is connected to the sludge collection port.

[0037] During the wastewater recycling process of the robotic vacuum cleaner, the base station uses a vacuum pump to draw air from the wastewater tank 1, creating negative pressure within the tank. This negative pressure is then used to draw wastewater from the cleaning tray inside the base station through a pipe connected to the outlet 112 located inside the collection tank 11. The wastewater collected from the robotic vacuum cleaner by the cleaning tray is then sent into the collection tank 11. Under gravity, the wastewater passes through the collection port and enters the filter screen 2, where it is filtered and flows back into the wastewater tank 1 for recycling. Meanwhile, large particles and large-volume debris cannot pass through the mesh of the filter screen 2 and remain inside. Over time, a large amount of debris accumulates inside the filter screen 2. Since the filter screen 2 is movably inserted into the slot 111 of the collection port, it can be easily removed for cleaning.

[0038] In this application, the sludge collection tank 11 and the filter screen 2 are located at the top edge of the sewage tank 1. Therefore, during actual operation, the filter screen 2 is always positioned above the highest water level of the sewage inside the sewage tank 1, separating the filtered waste residue from the sewage inside the tank 1 and suspending it at the top of the tank 1. This allows the waste residue inside the filter screen 2 to drain, preventing bacterial growth and unpleasant odors caused by prolonged moisture retention or immersion in sewage. Furthermore, positioning the filter screen 2 at the top of the sewage tank 1 facilitates its removal, eliminating the need to drain the sewage from the tank 1 before removing it. This significantly improves the efficiency of cleaning the filter screen 2 and allows for easy installation and removal at any time.

[0039] In some embodiments, please refer to Figure 3 The filter screen 2 includes an insert plate 21 and a mesh bag 22. The mesh bag 22 is disposed around the opening in the center of the insert plate 21. The two sides of the insert plate 21 are respectively inserted into the slots 111 on both sides of the sludge collection port. By inserting the two sides of the insert plate 21 into the slots 111 of the sludge collection tank 11, the filter screen 2 is connected and fixed to the sludge collection tank 11.

[0040] In some optional embodiments, the outlet 112 is positioned at a height higher than the bottom surface of the sludge collection tank 11. Simultaneously, a conical pedestal structure 113 is provided between the outlet 112 and the bottom surface of the sludge collection tank 11, allowing the wastewater discharged from the outlet 112 to flow downwards along the conical surface of the pedestal structure 113. The wastewater is then filtered through the mesh bag 22 of the filter screen 2 before flowing into the wastewater tank 1. In some optional embodiments, the outlet 112 faces the filter screen 2, ensuring that the wastewater, after being discharged from the outlet 112, enters the filter screen 2 via the shortest path, preventing debris and residue from accumulating inside the sludge collection tank 11 and hindering effective debris removal.

[0041] In some embodiments, the insert plate 21 is made of a rigid material, which facilitates a rigid connection between the insert plate 21 and the slot 111 of the sludge collection tank 11. This prevents the insert plate 21 from deforming and detaching from the slot 111 due to the impact of sewage flow or the negative pressure suction of a vacuum pump, thereby improving the overall structural stability and ensuring effective filtration of sewage. In some optional embodiments, rigid plastic is used as the material for the insert plate 21, which effectively ensures the structural stability of the insert plate 21 while reducing production and processing costs.

[0042] In some embodiments, the insert plate 21 is provided with a lifting structure, which is located at the top of the insert plate 21 when the insert plate 21 is inserted into the slot 111. By providing a lifting structure at the top of the insert plate 21, it is convenient to pull the filter screen 2 out of the slot 111 by gripping the lifting structure, facilitating the application of force on the insert plate 21. The lifting structure allows users to quickly grasp and remove the filter screen 2, improving the efficiency of filter screen 2 installation and removal.

[0043] In some alternative embodiments, the lifting structure is a strip-shaped hole, which allows the user to insert their fingernail into the strip-shaped hole to pinch the insert plate 21 and easily remove the filter screen 2 from the slot 111.

[0044] In some optional embodiments, the lifting structure is a bent structure 23, forming a latch that allows the user to hook the bent structure 23 with their fingers to remove the filter screen 2 from the slot 111. Simultaneously, when inserting the insert plate 21 of the filter screen 2 into the slot 111 of the sludge collection tank 11, the insert plate 21 can be pushed into the slot 111 by pressing the top of the bent structure 23. During the pushing of the insert plate 21, the bent structure 23 increases the contact area, thereby reducing the pressure exerted on the user's fingers and minimizing discomfort.

[0045] Secondly, please refer to Figure 1 , Figure 4 , Figure 5This application provides an automatic water supply and drainage module, including the sludge collection and filtration device described above, a sludge tank 1, and a cover structure 3, which covers the top of the sludge tank 1. The cover structure 3 covers the sludge tank 1, thereby preventing sludge overflow or splashing and thus preventing sludge pollution near the base station. In some embodiments, the sludge tank 1 for collecting sludge and the clean water tank 12 for supplying clean water are integrated into one structure, separated by a partition, thus forming an integrated automatic water supply and drainage module. The cover structure 3 effectively prevents sludge or dirt from falling into the clean water tank 12 and polluting the water body.

[0046] In some embodiments, the upper cover structure 3 is provided with a water-retaining frame 31 corresponding to the sludge collection tank 11, and the water-retaining frame 31 corresponds to each side wall of the sludge collection tank 11. The water-retaining frame 31 provides water protection above the sludge collection tank 11, preventing sewage entering the sludge collection tank 11 by vacuum pump from splashing and directly entering the sewage tank 1 without being filtered by the filter screen 2. This meets the requirement of effective sewage filtration, prevents sewage from carrying large particles of garbage residue into the sewage tank 1, and avoids the situation where sewage affects subsequent drainage, thus ensuring the stability of subsequent drainage work.

[0047] In some embodiments, the upper cover structure 3 is provided with an observation hole 32 corresponding to the sewage tank 1. By providing an observation hole 32 on the upper cover structure 3, it is convenient for users to observe the sewage level in the sewage tank 1. At the same time, it is also convenient for users to remove and assemble the filter screen 2 through the observation hole 32, and to clean up the garbage residue filtered out by the filter screen 2, so as to avoid the accumulation of garbage residue in the filter screen 2, which may cause odor or affect the water flow performance of the filter screen 2.

[0048] In some embodiments, a flip cover 4 is rotatably provided on the upper cover structure 3. One side of the flip cover 4 is hinged to the edge of the observation hole 32, and the flip cover 4 closes onto the observation hole 32. Under normal conditions, by closing the flip cover 4 onto the observation hole 32, the sewage tank 1 is sealed, which facilitates the suction of sewage into the collection tank 11 by the negative pressure generated by the vacuum pump, and prevents the negative pressure suction from leaking due to the open observation hole 32, thereby affecting the effect of sewage suction.

[0049] In some optional embodiments, a resilient snap-fit ​​structure 41 is provided on the end of the flip cover 4 away from the hinge position. When the flip cover 4 is closed on the observation hole 32, the resilient snap-fit ​​structure 41 is embedded in the groove on the side wall of the observation hole 32, thereby fixing the flip cover 4 on the observation hole 32 and ensuring the closing effect.

[0050] In some optional embodiments, a sealing groove 33 is provided around the outer side of the observation hole 32, and a sealing ring 34 is provided in the sealing groove 33. When the flip cover 4 is closed on the observation hole 32, the flip cover 4 presses against the sealing ring 34, causing the sealing ring 34 to deform under pressure, thereby filling the gap between the flip cover 4 and the upper cover structure 3, thus achieving a sealing effect. The sealing effect of the sealing ring 34 ensures that the negative pressure generated by the vacuum pump can effectively draw in sewage, allowing the sewage to enter the sludge collection tank 11, and then filter out the garbage residue in the sewage through the filter screen 2. At the same time, the sealing ring 34 ensures the sealing effect between the flip cover 4 and the upper cover structure 3, thereby preventing the odor generated in the sewage tank from spreading to the outside environment and causing discomfort to the user.

[0051] In some embodiments, a drain outlet is provided at the bottom of the sewage tank 1, and the drain outlet is connected to a sewage pump 5 via a pipe. When discharging sewage from the sewage tank 1, the sewage pump 5 is started, and a one-way valve is opened simultaneously to open the drain pipe, allowing the sewage to be discharged out of the sewage tank 1. Since the filter screen 2 is located at the top of the sewage tank 1 and effectively filters large particles of debris in the sewage, there is no problem of debris clogging the drain pipe, effectively improving the stability of the drainage operation.

[0052] In some optional embodiments, the bottom surface of the sewage tank 1 is provided with an inclined surface or arc surface that slopes towards the drain outlet, so that the drain outlet is located at the lowest point in the cavity of the sewage tank 1. This allows the sewage in the sewage tank 1 to flow along the inclined surface or arc surface to the drain outlet, facilitating the complete discharge of sewage from the sewage tank 1. This arrangement avoids the situation where sewage cannot be completely discharged during drainage, and residual sewage will breed bacteria, scale, etc. in the sewage tank 1, resulting in an odor. In the embodiments provided in this application, by setting the sludge collection tank and filter screen at the top edge of the sewage tank, effective filtration of sewage is ensured while preventing the garbage residue filtered out of the filter screen from coming into contact with the sewage in the sewage tank. This facilitates the draining of garbage residue and prevents the emission of odor due to prolonged soaking in sewage. At the same time, inserting the filter screen into the slot of the sludge collection tank at the top edge of the sewage tank also makes it easy for users to remove and install the filter screen from the sludge collection tank, making it convenient to remove the filter screen for cleaning, ensuring that the efficiency of sewage filtration through the filter screen is not affected by the accumulation of garbage residue.
