[0002] With the development of smart homes, various intelligent cleaning devices have been widely used in households, becoming helpful assistants for home cleaning. Common intelligent cleaning devices include cleaning robots, floor scrubbers, and vacuum cleaners. These devices work by using negative pressure to draw a solid-liquid mixture from the floor into a wastewater tank. Inside the tank, a filtration system divides the interior into a solid waste compartment and a liquid storage compartment. The filtration system filters the solid-liquid mixture from the wastewater, removing solid waste, while the filtered liquid is stored in the liquid storage compartment.

[0003] In related technologies, traditional cleaning equipment achieves solid-liquid separation through separators and filters fixed to the sewage tank. However, this results in a large number of internal parts and a complex structure in the sewage tank, making it difficult to thoroughly clean the internal structure, leaving residual dirt, and making filter maintenance difficult.

[0039] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0040] The following is for reference. Figures 1-9 The wastewater tank 100 according to the present utility model embodiment can, while ensuring the stable function of the solid-liquid separator 22, also facilitate the user to disassemble and replace the solid-liquid separator 22, thereby improving the ease of assembly and disassembly and cleaning efficiency.

[0041] Combination Figures 1-9 As shown, the sewage tank 100 according to the first aspect of the present invention includes a tank body 10 and a tank cover assembly 20. The tank body 10 serves as the main load-bearing structural component of the external contour of the sewage tank 100 and can be used to contain sewage. The tank cover assembly 20 typically cooperates with the tank body 10 to ensure the airtightness of the sewage tank 100 and can also provide an installation carrier for related structures.

[0042] Specifically, the lid assembly 20 is disposed on the box body 10. The lid assembly 20 includes a support member 21 and a solid-liquid separator 22. The solid-liquid separator 22 is detachably connected to the support member 21. Along the length direction of the box body 10, at least a portion of the solid-liquid separator 22 extends toward the side away from the support member 21.

[0043] Specifically, the support member 21 can provide a load-bearing support for the solid-liquid separator 22, which can be used to separate the solid-liquid mixture entering the sewage tank 100, thereby collecting the solid waste after solid-liquid separation, facilitating classification and cleaning, and improving cleaning efficiency.

[0044] Moreover, compared to the traditional separators and filters installed along the thickness of the tank body inside the sewage tank (which limit the amount of solid waste that can be contained due to the small vertical dimensions of the separators, filters, and inner walls of the tank cover), in the embodiment of this case, at least part of the solid-liquid separator 22 extends away from the support member 21 along the length of the tank body 10. This increases the vertical (i.e., the length of the tank body 10) filtration range of the solid-liquid separator 22 when separating the solid-liquid mixture, and also increases the amount of solid waste that can be contained in the sewage tank 100, thereby reducing the cleaning cycle of solid waste.

[0045] Furthermore, the solid-liquid separator 22 is detachably connected to the support 21, allowing users to easily install and remove it from the support 21 according to their cleaning needs, thereby improving cleaning thoroughness and convenience. Compared to traditional methods that use non-removable filters and dividers on the housing, where the filter cannot be removed individually and the dividers obstruct the filter, making it difficult to thoroughly clean solid waste adhering to the filter and maintain or replace it, the embodiment in this case allows for flexible installation and removal of the solid-liquid separator 22. This facilitates thorough cleaning of the separator 22, avoids cleaning dead spots, and also facilitates maintenance and replacement, thereby improving cleaning efficiency and enhancing the user's cleaning experience. In addition, the solid-liquid separator 22 in this case has a simple structure and is easy to assemble.

[0046] Therefore, by setting up the sewage tank 100, the solid-liquid separation component 22 can be easily disassembled and replaced by the user while ensuring the stable function of the solid-liquid separation component 22, thereby improving the convenience of disassembly and cleaning efficiency; moreover, the structure is simple and the assembly is easy.

[0047] According to some optional embodiments of the present invention, combined with Figures 2-5 As shown, the support member 21 is provided with a first insertion part 211, and the solid-liquid separation member 22 is provided with a second insertion part 221. The first insertion part 211 and the second insertion part 221 are inserted and fitted together along the length direction of the box body 10.

[0048] Along the length of the housing 10, the first insertion part 211 on the support member 21 and the second insertion part 221 on the solid-liquid separator 22 are interlocked. This allows users to quickly and manually complete the connection or separation without professional tools, effectively shortening the disassembly and assembly time and improving efficiency. The interlocking also naturally guides the support member 21 and the solid-liquid separator 22 to align correctly, avoiding installation deviations and ensuring connection accuracy. Furthermore, compared to screwed or adhesive connections, the interlocking connection eliminates the need for additional fasteners (such as screws) or adhesives, simplifying the production process.

[0049] Specifically, the first insertion part 211 is configured as either a rod or a slot, and the second insertion part 221 is configured as either a rod or a slot, with the rod and slot being inserted and engaged.

[0050] Alternatively, the first insertion part 211 can be a plug rod, and the second insertion part 221 can be a slot; the first insertion part 211 can also be a slot, and the second insertion part 221 can be a plug rod. For example, the first insertion part 211 is constructed as a plug rod, and the second insertion part 221 is constructed as a slot. The plug rod and the slot are inserted and fitted together as a whole along the length of the housing 10, which can achieve the effect of flexibly assembling and disassembling the solid-liquid separator 22.

[0051] According to some optional embodiments of the present invention, combined with Figures 2-4 , Figure 6 , Figure 8 and Figure 9 As shown, the support member 21 is provided with a first snap-fit ​​part 212, and the solid-liquid separation member 22 is provided with a second snap-fit ​​part 222. The first snap-fit ​​part 212 and the second snap-fit ​​part 222 are snap-fitted together along the width or thickness direction of the box body 10.

[0052] In this configuration, along the width or thickness direction of the housing 10, the first snap-fit ​​portion 212 on the support member 21 and the second snap-fit ​​portion 222 on the solid-liquid separator 22 are snap-fitted together, thus connecting the support member 21 and the solid-liquid separator 22 into a single unit. Moreover, compared to other connection methods (such as screwing, bonding, etc.), the snap-fit ​​connection does not require additional parts to connect the support member 21 and the solid-liquid separator 22 into a single unit, avoiding unnecessary material consumption. It also provides sufficient connection holding force for the support member 21 and the solid-liquid separator 22, ensuring that the solid-liquid separator 22 will not detach from the support member 21.

[0053] Moreover, the snap-fit ​​connection structure is simple and reliable, and has quick and convenient disassembly and installation functions (that is, it can realize the quick connection and separation of the support 21 and the solid-liquid separation component 22), which can effectively reduce the time and cost required for maintenance and replacement.

[0054] Specifically, the first snap-fit ​​part 212 is constructed as either a snap hook or a snap groove, and the second snap-fit ​​part 222 is constructed as either a snap hook or a snap groove, with the snap hook and snap groove engaging in a snap-fit ​​engagement.

[0055] Alternatively, the first snap-fit ​​portion 212 can be a slot, and the second snap-fit ​​portion 222 can be a hook; the first snap-fit ​​portion 212 can also be a hook, and the second snap-fit ​​portion 222 can be a slot. For example, the first snap-fit ​​portion 212 can be constructed as a slot, and the second snap-fit ​​portion 222 can be constructed as a hook. The hook and the slot are snapped together as a whole along the width or thickness direction of the housing 10, thus achieving the effect of flexibly assembling and disassembling the solid-liquid separator 22.

[0056] Alternatively, the support member 21 is provided with a first insertion part 211 and a first snap-fit ​​part 212, and the solid-liquid separator 22 is provided with a second insertion part 221 and a second snap-fit ​​part 222. The support member 21 and the solid-liquid separator 22 are inserted together through the first insertion part 211 and the second insertion part 221, and they are also snapped together through the first snap-fit ​​part 212 and the second snap-fit ​​part 222. In this way, the support member 21 and the solid-liquid separator 22 are connected into a whole through multiple connection methods. This can effectively enhance the connection contact area and force transmission path between the two, avoid the risk of failure of a single connection method, and thus effectively improve the connection reliability and force uniformity between the two.

[0057] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 2 As shown, the solid-liquid separator 22 includes a side separation part 223 and a bottom separation part 224. The side separation part 223 is detachably connected to the support member 21 and extends along the length direction of the housing 10. The bottom separation part 224 is connected to the end of the side separation part 223 away from the support member 21 and is bent relative to the side separation part 223.

[0058] Specifically, along the length of the container 10, the end of the side separation part 223 near the support member 21 is detachably connected to the support member 21. The side separation part 223 extends along the length of the container 10, thus extending the vertical dimension of the solid-liquid separator 22 within the container 10 and increasing the vertical space for solid waste within the sewage tank 100. Furthermore, the bottom separation part 224 is connected to the end of the side separation part 223 away from the support member 21, and the bottom separation part 224 is bent relative to the side separation part 223. This facilitates the bottom separation part 224 in separating the internal space of the container 10 along its length, allowing the bottom separation part 224 to support the solid waste under it during the process of the user retrieving the solid-liquid separator 22, preventing the solid waste from falling back into the sewage and making it easier for the user to clean up the solid waste.

[0059] Alternatively, when the cleaning equipment is in operation or stationary (except in a lying position), combined with Figure 1 , Figure 4 and Figure 5 As shown, two first insertion portions 211 are located on both sides of the support member 21 in the width direction, and both first insertion portions 211 are located in the middle of the support member 21. Correspondingly, two second insertion portions 221 are provided on the top of the solid-liquid separation member 22; combined with... Figure 1 , Figure 4 and Figure 6 As shown, the two first snap-fit ​​portions 212 are also located on both sides of the width direction of the support member 21, and the two first snap-fit ​​portions 212 are located at the bottom of the support member 21 and are spaced apart from the first plug-in portion 211. The solid-liquid separator 22 is correspondingly provided with two second snap-fit ​​portions 222 in the middle. This makes it easy for the support member 21 and the solid-liquid separator 22 to establish a connection relationship in different directions and heights, thereby ensuring the overall connection reliability of the two.

[0060] Alternatively, combine Figure 8 and Figure 9 As shown, two first snap-fit ​​parts 212 are provided on both sides of the support member 21 in the width direction. The two first snap-fit ​​parts 212 on each side are spaced apart along the length direction of the box body 10. The top of the solid-liquid separator 22 is provided with four second snap-fit ​​parts 222. This facilitates the establishment of a firm connection between the support member 21 and the solid-liquid separator 22, thereby ensuring the overall reliability of the connection between the two.

[0061] Furthermore, combined Figures 2-4 and Figure 7 As shown, the bottom of the bottom separation section 224 has a protruding third insertion section 2241; the sewage tank 100 also includes a deodorizing component 30, which has an insertion hole 31 that engages with the third insertion section 2241. The deodorizing component 30 can directly intercept, neutralize, or decompose odor molecules at the source of the odor through physical adsorption (such as activated carbon), chemical decomposition (such as oxidants), or biodegradation (such as microbial flora), preventing odors from spreading from the gaps and exhaust vents of the sewage tank 100 into the surrounding environment, thus ensuring the respiratory health and psychological comfort of users during their activities in the surrounding area.

[0062] Understandably, the bottom of the bottom separation part 224 protrudes towards the bottom wall of the housing 10 and has a third insertion part 2241. The third insertion part 2241 and the insertion hole 31 on the deodorizing component 30 are inserted into each other. This allows users to quickly and manually complete the connection or separation without professional tools, effectively shortening the disassembly and assembly time and improving efficiency. The insertion also naturally guides the deodorizing component 30 and the bottom separation part 224 to be aligned, avoiding installation deviations and ensuring connection accuracy. In addition, compared with screw connections and adhesive connections, the insertion connection does not require additional fasteners (such as screws) or adhesives, thus simplifying the assembly process.

[0063] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 7 As shown, the support member 21 is provided with a sewage inlet 216, and the end face of the sewage inlet 216 is an inclined surface that is inclined relative to the length direction of the box body 10.

[0064] The inlet 216 on the support member 21 is connected to the suction pipe. The inlet 216 can introduce sewage from the suction pipe into the sewage tank 100. The end face of the inlet 216 is constructed as an inclined surface relative to the length direction of the tank 10. Compared with the traditional design of the end face of the inlet as a horizontal surface, the embodiment in this case can increase the water inlet end face area of ​​the inlet 216, improve the sewage intake efficiency, and improve the end face angle of the inlet 216, making it easier to cooperate with external faucets, thereby improving the convenience and thoroughness of cleaning the sewage intake path.

[0065] Specifically, in combination Figure 1 and Figure 7 As shown, in the thickness direction of the housing 10, the lower end of the inclined surface is closer to the solid-liquid separator 22 than the upper end of the inclined surface.

[0066] Understandably, in the clean or static state (not lying flat), relative to the clean surface, in the thickness direction of the housing 10, the lower end of the inclined surface is closer to the solid-liquid separator 22 than the upper end of the inclined surface. This facilitates the improvement of the end face angle of the inlet 216, which is beneficial for users to attach the inlet 216 to the faucet and directly clean the inlet 216 with running water.

[0067] Furthermore, combined Figure 7 As shown, the inclined plane forms an angle α with the length direction of the box 10, and α satisfies the relationship: 20°≤α≤70°.

[0068] In other words, when the angle formed between the inclined plane and the length direction of the tank 10 is less than 20°, there is a risk that the angle may be too small to effectively increase the inlet area and improve the inlet angle of the sewage inlet 216. Conversely, when the angle formed between the inclined plane and the length direction of the tank 10 is greater than 70°, there is a risk that the angle may be too large to effectively increase the inlet area and improve the inlet angle of the sewage inlet 216. Therefore, controlling the angle between the inclined plane and the length direction of the tank 10 within a reasonable range can effectively ensure both the inlet area and the inlet angle of the sewage inlet 216, thereby improving the sewage intake efficiency and cleaning effect at the sewage inlet 216. For example, the angle between the inclined plane and the length direction of the tank 10 can be 20°, 30°, 45°, or 70°, and is not limited to these.

[0069] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 7 As shown, the support member 21 is provided with a sewage discharge channel 213, which includes a first sewage discharge section 214 and a second sewage discharge section 215. The first sewage discharge section 214 extends along the thickness direction of the box body 10, and the second sewage discharge section 215 extends along the length direction of the box body 10. One end of the first sewage discharge section 214 and one end of the second sewage discharge section 215 are connected. The other end of the first sewage discharge section 214 forms a sewage inlet 216, and the other end of the second sewage discharge section 215 forms a sewage outlet 217. The sewage outlet 217 is set towards the bottom wall of the box body 10.

[0070] Specifically, the first sewage discharge section 214 and the second sewage discharge section 215 are interconnected. The first sewage discharge section 214 extends along the thickness direction of the tank body 10, and the second sewage discharge section 215 extends along the length direction of the tank body 10. The sewage inlet 216 on the first sewage discharge section 214 is connected to the sewage suction pipe. This facilitates the flow of dirt along the path of the sewage suction pipe - the first sewage discharge section 214 - the second sewage discharge section 215, thereby successfully achieving the effect of sucking dirt from the clean surface into the sewage tank 100.

[0071] Furthermore, since the first drainage section 214 extends along the thickness direction of the tank 10, even when the sewage tank 100 is in a flat position, the dirt inside the sewage tank 100 must submerge the thickness of the first drainage section 214 before it can flow back into the suction pipe. Compared to the traditional structure that uses partitions to prevent sewage backflow, the embodiment in this case can effectively achieve the sewage backflow prevention effect without increasing the number of additional parts, thereby improving practicality and economy. In addition, the embodiment in this case has a simpler structure.

[0072] According to a second aspect embodiment of the present invention, a sewage tank 100 includes a tank body 10 and a tank cover assembly 20. The tank cover assembly 20 includes a support member 21 and a solid-liquid separator 22. The solid-liquid separator 22 is detachably connected to the support member 21. The support member 21 is provided with a sewage inlet 216. Along the thickness direction of the tank body 10, the solid-liquid separator 22 is located on one side of the sewage inlet 216.

[0073] In contrast to the traditional method of placing separators and filters along the thickness of the sewage tank (which limits the amount of solid waste that can be contained due to the small vertical dimensions of the separators, filters, and inner walls of the tank cover), in this embodiment, the solid-liquid separator 22 is located on one side of the inlet 216 along the thickness of the tank 10. This increases the vertical (i.e., the length of the tank 10) filtration range of the solid-liquid separator 22 when separating the solid-liquid mixture, and also increases the amount of solid waste that can be contained in the sewage tank 100, thereby reducing the cleaning cycle of solid waste.

[0074] Furthermore, the solid-liquid separator 22 is detachably connected to the support 21, allowing users to easily install and remove it from the support 21 according to their cleaning needs, thereby improving the thoroughness and convenience of cleaning. Compared to the traditional method of installing non-removable filters and separators on the housing, where the filter cannot be removed individually and the separators obstruct the filter, making it difficult to thoroughly clean solid waste adhering to the filter and maintain or replace it, the embodiment in this case allows for flexible installation and removal of the solid-liquid separator 22. This facilitates thorough cleaning of the separator 22, avoids cleaning dead spots, and makes maintenance and replacement of the separator 22 easier, thus improving cleaning efficiency and enhancing the user's cleaning experience. Moreover, the solid-liquid separator 22 in this case has a simple structure and is easy to assemble.

[0075] Specifically, in combination Figures 2-5 As shown, the support member 21 is provided with a first insertion part 211, and the solid-liquid separation member 22 is provided with a second insertion part 221. The first insertion part 211 and the second insertion part 221 are inserted and fitted together along the length direction of the box body 10.

[0076] Along the length of the housing 10, the first insertion part 211 on the support member 21 and the second insertion part 221 on the solid-liquid separator 22 are interlocked. This allows users to quickly and manually complete the connection or separation without professional tools, effectively shortening the disassembly and assembly time and improving efficiency. The interlocking also naturally guides the support member 21 and the solid-liquid separator 22 to align correctly, avoiding installation deviations and ensuring connection accuracy. Furthermore, compared to screwed or adhesive connections, the interlocking connection eliminates the need for additional fasteners (such as screws) or adhesives, simplifying the production process.

[0077] Furthermore, combined Figures 2-4 and Figure 6 As shown, the support member 21 is provided with a first snap-fit ​​part 212, and the solid-liquid separation member 22 is provided with a second snap-fit ​​part 222. The first snap-fit ​​part 212 and the second snap-fit ​​part 222 are snap-fitted together along the width or thickness direction of the box body 10.

[0078] In this configuration, along the width or thickness direction of the housing 10, the first snap-fit ​​portion 212 on the support member 21 and the second snap-fit ​​portion 222 on the solid-liquid separator 22 are snap-fitted together, thus connecting the support member 21 and the solid-liquid separator 22 into a single unit. Moreover, compared to other connection methods (such as screwing, bonding, etc.), the snap-fit ​​connection does not require additional parts to connect the support member 21 and the solid-liquid separator 22 into a single unit, avoiding unnecessary material consumption. It also provides sufficient connection holding force for the support member 21 and the solid-liquid separator 22, ensuring that the solid-liquid separator 22 will not detach from the support member 21.

[0079] Moreover, the snap-fit ​​connection structure is simple and reliable, and has quick and convenient disassembly and installation functions (that is, it can realize the quick connection and separation of the support 21 and the solid-liquid separation component 22), which can effectively reduce the time and cost required for maintenance and replacement.

[0080] The cleaning equipment according to a third aspect embodiment of the present invention includes the wastewater tank 100 of the above embodiment.
