[0046] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0047] like Figures 1 to 4As shown, this embodiment first provides a self-cleaning sewage treatment device, which includes a sewage tank 1, a self-cleaning component 2, and a sewage discharge component 3. The sewage tank 1 is used to hold sewage generated during operation, and the sewage tank 1 has a sewage discharge port 11. The self-cleaning component 2 includes a cleaning inlet pipe 21 and a spray component 22 connected to each other. The spray component 22 is disposed inside the sewage tank 1, and the outlet end of the cleaning inlet pipe 21 is connected to the spray component 22. The cleaning inlet pipe 21 is used to provide cleaning water to the spray component 22, and the spray component 22 is used to spray and clean the inside of the sewage tank 1. By spraying cleaning water into the sewage tank 1 through the spray component 22, the amount of dirt remaining in the sewage tank 1 is reduced, and the dirt that adheres to the inner wall of the sewage tank 1 after long-term use is prevented from being difficult to remove. The sewage tank 1 does not need to be manually cleaned by the user, thus improving the user's convenience. Furthermore, the sewage discharge assembly 3 includes a discharge pipe 31 connected to the sewage outlet 11, an automatic drainage pipe 32, and a manual drainage pipe 33. Both the automatic drainage pipe 32 and the manual drainage pipe 33 are connected to the discharge pipe 31. The automatic drainage pipe 32 is equipped with a sewage discharge valve 34, and the discharge end of the manual drainage pipe 33 is equipped with a removable sealing element 35. Either the discharge end of the automatic drainage pipe 32 or the discharge end of the manual drainage pipe 33 can be selectively connected to the discharge pipe 31. Automatic sewage discharge can be achieved by opening the sewage discharge valve 34, or manual sewage discharge can be achieved by opening the sealing element 35, meeting different sewage discharge needs of users. The sewage tank 1 only needs to have one sewage outlet 11, simplifying the structure of the sewage tank 1, reducing volume restrictions on the sewage tank 1, and lowering the production cost of the sewage tank 1. Moreover, it facilitates simplified pipeline layout, as only one of the automatic drainage pipe 32 and the manual drainage pipe 33 needs to be selectively connected to the discharge pipe 31, reducing the space occupied. The selective connection of the automatic drain pipe 32 or the manual drain pipe 33 is simple to operate. By removing and installing the sealing component 35 and opening and closing the drain valve 34, there will be no interference or influence between them, making the operation relatively convenient.

[0048] It should be noted that automatic sewage discharge is achieved through an external workstation, typically at a set time or after the sewage tank 1 is full. Manual sewage discharge can be performed at any time according to user habits and cleaning needs; this embodiment does not impose any restrictions on this. To ensure that as much sewage as possible is discharged, the drain outlet 11 is located at the bottom of the sewage tank 1, which can be the bottom wall of the sewage tank 1 or the bottom of the side wall of the sewage tank 1, depending on the internal space of the self-cleaning sewage treatment device.

[0049] In order to connect the discharge pipe 31 with the automatic drain pipe 32 and the manual drain pipe 33, the sewage discharge assembly 3 also includes a three-way connector 36. The three-way connector 36 includes an outlet 361, a first connecting port 362 and a second connecting port 363 that are connected to each other. The outlet 361 is connected to the discharge pipe 31, the first connecting port 362 is connected to the automatic drain pipe 32, and the second connecting port 363 is connected to the manual drain pipe 33.

[0050] The sewage discharge assembly 3 also includes a drain connector 37, which is located at the discharge end of the automatic drain pipe 32 and is configured to connect to an external workstation (not shown in the figure). Automatic sewage discharge is achieved through the connection between the drain connector 37 and the external workstation, making the sewage discharge process convenient and reliable. The specific structure of the drain connector 37 can refer to existing technologies and be configured according to the structure of the external workstation; this embodiment does not impose any limitations on this.

[0051] In one embodiment, the self-cleaning sewage treatment device further includes a housing 4, with a sewage tank 1 disposed on top of the housing 4. The housing 4 includes a chassis 41 with an installation opening. A manual drain pipe 33 passes through the installation opening and extends to the outside of the housing 4. The housing 4 can constrain the manual drain pipe 33 to prevent it from shaking. Moreover, the downward-extending manual drain pipe 33 is easy to align with a floor drain and can drain sewage by gravity.

[0052] The sealing element 35 is detachably connected to the manual drain pipe 33 and located on the outside of the chassis 41. The sealing element 35 can be a threaded plug, and the manual drain pipe 33 is provided with external or internal threads. The sealing element 35 and the manual drain pipe 33 are threadedly connected, making it easy to assemble and disassemble. Moreover, the sealing element 35 is located on the outside of the chassis 41, which facilitates manual drainage operations from the outside of the housing 4 without having to open the housing 4, making the drainage operation more convenient.

[0053] In one embodiment, the self-cleaning component 2 further includes a booster pump 23, which is disposed in the cleaning inlet pipe 21. The spray element 22 is a rotating nozzle, and the booster pump 23 is configured to drive the rotating nozzle to rotate. The booster pump 23 increases the water pressure in the cleaning inlet pipe 21, causing the rotating nozzle to rotate. The rotating nozzle forms a rotating spray, which, on the one hand, has a large spray impact force, which can clean the dirt on the inner surface of the sewage tank 1 more thoroughly, and on the other hand, the spray coverage area is large. The specific structure of the spray element 22 and the principle of rotation using water pressure can be set with reference to the prior art, which is not the focus of this application.

[0054] The spray element 22 is located at the bottom of the sewage tank 1. The upward flushing force can effectively flush and remove dirt adhering to the inner wall of the sewage tank 1. The upward spraying method can flush the inside of the top cover of the sewage tank 1, achieving a thorough cleaning of the sewage tank 1 without any dead corners.

[0055] This utility model embodiment further provides a sweeping robot device, which includes the self-cleaning wastewater treatment device as described in any of the above embodiments. The sweeping robot device also includes a clean water supply component 100 and a disc brush cleaning component 200. The clean water supply component 100 provides clean water to the disc brush cleaning component 200. The cleaning inlet pipe 21 of the self-cleaning wastewater treatment device is connected to the clean water tank 101 of the clean water supply component 100. The self-cleaning wastewater treatment device uses the clean water in the clean water tank 101 to spray and clean the wastewater tank 1, eliminating the need for an external water source and making it convenient to use. The wastewater discharge component 3 of the self-cleaning wastewater treatment device can achieve automatic wastewater discharge by opening the discharge valve 34, or manual wastewater discharge by opening the sealing component 35, meeting different wastewater discharge needs of users. The wastewater tank 1 only needs one discharge port 11, simplifying its structure, reducing volume restrictions, and lowering production costs. Furthermore, it simplifies piping layout; either the automatic drain pipe 32 or the manual drain pipe 33 can be selectively connected to the discharge pipe 31, reducing space requirements. The selective connection of the automatic or manual drain pipe 33 is simple, controlled by the removal and installation of the sealing component 35 and the opening and closing of the drain valve 34, preventing interference and improving the ease of use of the sweeping robot, thus facilitating overall miniaturization.

[0056] The specific structure and cleaning principle of the disc brush cleaning component 200 can be set with reference to existing technology, and this embodiment does not impose any limitations.

[0057] The sweeping robot also includes a first electric valve 300, which is located in the cleaning water inlet pipe 21 and is used to control the opening and closing of the cleaning water inlet pipe 21. The first electric valve 300 controls the supply of water to the self-cleaning sewage treatment device, providing clean water only when the sewage tank 1 needs to be self-cleaned.

[0058] The robotic vacuum cleaner also includes a liquid supply pipe 401 and a cleaning liquid assembly 500. The cleaning liquid assembly 500 supplies cleaning liquid to the disc brush cleaning assembly 200. The liquid supply pipe 401 is equipped with a second electric valve 402, which controls the liquid supply pipe 401 to only connect when the disc brush cleaning assembly 200 needs cleaning liquid. The inlet end of the liquid supply pipe 401 is connected to the cleaning liquid assembly 500 and the clean water supply assembly 100, and the outlet end of the liquid supply pipe 401 is connected to the disc brush cleaning assembly 200. The cleaning liquid provided by the cleaning liquid assembly 500 and the clean water provided by the clean water supply assembly 100 are mixed in the liquid supply pipe 401 and supplied to the disc brush cleaning assembly 200. The structure is relatively compact and does not require an additional mixing container.

[0059] In one embodiment, the cleaning fluid assembly 500 includes a cleaning fluid container 501 and a cleaning fluid pump 502. The cleaning fluid container 501 is connected to the inlet end of the supply pipe 401, and the cleaning fluid pump 502 is disposed on the supply pipe 401. The cleaning fluid pump 502 provides power for the flow of the cleaning fluid, and the cleaning fluid container 501 is used to hold the cleaning fluid.

[0060] In one embodiment, such as Figure 5 As shown, the cleaning fluid pump 502 includes a cleaning fluid pump housing 5021, a cleaning fluid pump head 5022 disposed inside the cleaning fluid pump housing 5021, and a cleaning fluid pump cover plate 5023 covering the cleaning fluid pump housing 5021, thereby improving the reliability of the cleaning fluid pump 502.

[0061] The sweeping robot also includes a suction assembly 600, which comprises a suction fan 601, a first filter 602, a squeegee 603, and a suction pipe 604. The air inlet of the suction fan 601 is connected to the wastewater tank 1 of the self-cleaning wastewater treatment device. The suction fan 601 creates negative pressure inside the wastewater tank 1, thereby adsorbing wastewater and other dirt. To prevent dirt or water mist from entering the suction fan 601, a first filter 602 is installed between the suction fan 601 and the wastewater tank 1. The suction fan 601 is configured to create negative pressure inside the wastewater tank 1. The squeegee 603 is located beside the disc brush cleaning assembly 200 and is used to collect wastewater. One end of the suction pipe 604 is connected to the squeegee 603, and the other end is connected to the wastewater tank 1. A second filter 605 is installed between the suction pipe 604 and the wastewater tank 1. The second filter element 605 filters solid impurities from the sewage and waste adsorbed by the squeegee 603, reducing the amount of impurities entering the sewage tank 1. The suction fan 601 maintains air pressure balance through the exhaust pipe 606.

[0062] In one embodiment, such as Figure 6 As shown, the first filter element 602 includes a filter box 6021, a HEPA filter 6023 disposed within the filter box 6021, and a filter box cover 6022 covering the filter box 6021. The HEPA filter 6023 can be replaced according to the usage time. The second filter element 605 adopts a high-efficiency particulate filter basket, and its specific structure and filtration principle can be set with reference to existing technology.

[0063] The robotic vacuum cleaner also includes a filter assembly 700, which comprises a filter 701 and a switching valve 702. The clean water supply assembly 100 further includes a first electromagnetic pump mechanism 102 and a clean water inlet pipe 103. One end of the clean water inlet pipe 103 is connected to a clean water tank 101, and the first electromagnetic pump mechanism 102 is connected to the other end of the clean water inlet pipe 103 away from the clean water tank 101. The first electromagnetic pump mechanism 102 provides power to the clean water. The filter assembly 700 is positioned between the clean water inlet pipe 103 and the first electromagnetic pump mechanism 102, along the direction of clean water flow. The switching valve 702 is located upstream of the filter 701. The filter assembly 700 filters the clean water, preventing impurities in the water from entering the first electromagnetic pump mechanism 102. The filter assembly 700 is removable for cleaning; closing the switching valve 702 disconnects the clean water inlet pipe 103, preventing leakage.

[0064] In one embodiment, the first electromagnetic pump mechanism 102 includes a housing 1021, a cover 1022, and at least two first electromagnetic pumps 1023. The housing 1021 has a mounting cavity; the cover 1022 is detachably fitted onto the housing 1021 to close the mounting cavity; the first electromagnetic pumps 1023 are disposed within the housing 1021, and at least two first electromagnetic pumps 1023 are connected in parallel. For example, as... Figure 7 As shown in the figure, the first electromagnetic pump mechanism 102 includes two first electromagnetic pumps 1023 connected in parallel. The two first electromagnetic pumps 1023 connected in parallel can increase the pumping flow of the first electromagnetic pump mechanism 102, making the water flow larger and improving the cleaning efficiency of the sweeping robot equipment.
