Description

Technical Field

[0001] This invention relates to the field of household washing and cleaning technology, and in particular to a wastewater tank for a cleaning machine and the cleaning machine itself. Background Technology

[0002] In recent years, floor scrubbers have become a common cleaning appliance in modern households. They are equipped with a water tank to store clean water, and while the roller brushes rotate and sweep the floor, water is sprayed onto the brushes. The resulting wastewater, softened by the scrubbing, is sucked into the wastewater tank. This combines vacuuming and floor scrubbing in one appliance, capable of handling both dry and wet waste. Examples include Chinese invention patent application number CN202410021209.X (publication number CN117617834A) and Chinese utility model patent number ZL202322358969.3 (authorization announcement number CN220502742U).

[0003] Existing wastewater tank structures for floor scrubbers often feature a one-piece molded tank body with a wastewater inlet guide pipe, as seen in Chinese utility model patents ZL202320628929.3 (authorization announcement number CN219846388U) entitled "A Wastewater Tank and Cleaning Machine for a Cleaning Machine" and ZL 202222312835.3 (authorization announcement number CN218279532U) entitled "A Wastewater Tank for a Cleaning Machine." However, the guide pipe design complicates the internal structure of the tank, easily creating cleaning dead zones and hindering thorough cleaning of the tank's interior.

[0004] Furthermore, the floor scrubber has two operating modes: upright and horizontal. In the horizontal mode, the scrubber can clean under sofas, beds, and other surfaces. However, in the existing horizontal mode, when the wastewater tank is full, wastewater can enter the inlet pipe, causing water to splash as the air is blown out. This not only reduces the actual capacity of the wastewater tank but also allows wastewater to overflow and contaminate the floor. Additionally, it makes the blower more susceptible to drawing in wastewater, potentially damaging the blower and shortening its lifespan. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide a wastewater tank for a cleaning machine that has a simple structure and can separate gaseous waste from solid and liquid waste, in contrast to the prior art.

[0006] The second technical problem to be solved by the present invention is to provide a wastewater tank for a cleaning machine that has a simple structure and can separate gaseous waste, sewage and solid waste, in contrast to the prior art.

[0007] The third technical problem to be solved by the present invention is to provide a sewage tank for a cleaning machine that can prevent sewage from entering the sewage inlet channel in a flat state and can ensure the actual water capacity, in contrast to the prior art.

[0008] The fourth technical problem to be solved by the present invention is to provide a wastewater tank for a cleaning machine that can prevent wastewater from entering the blower when the machine is in a flat position, in contrast to the prior art.

[0009] The fifth technical problem to be solved by the present invention is to provide a cleaning machine having the above-mentioned sewage tank, in contrast to the prior art.

[0010] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is: a wastewater tank for a cleaning machine, comprising:

[0011] The barrel body has an opening at the first end;

[0012] The separator is sealed and installed in the opening of the barrel body, and includes a separator located in the barrel body and an air outlet exposed outside the barrel body;

[0013] An air outlet is provided on the air outlet of the aforementioned separation seat and communicates with the inner cavity of the aforementioned barrel.

[0014] Its characteristic is that it further includes:

[0015] A sludge inlet channel is located in the separation section of the aforementioned separation seat along the length of the tank body. One end opens as a sludge inlet and bends to one side, opening onto the side wall of the tank body. The other end opens as a sludge outlet facing the second end of the tank body.

[0016] An airflow channel is provided in the separation section and is respectively provided on both sides of the inlet channel along the width direction of the barrel;

[0017] Furthermore, each of the aforementioned airflow channels extends along the length of the barrel, and the air inlet port of each airflow channel is arranged in parallel with the aforementioned sewage outlet, while the air outlet port is in fluid communication with the aforementioned sewage outlet.

[0018] Furthermore, the separation section extends along the longitudinal section of the tank body and divides the inner cavity of the tank body into an airflow zone and a water flow zone when it is lying flat. The aforementioned sewage inlet channel and each airflow channel are located in the aforementioned airflow zone. On the one hand, this can prevent sewage from entering the sewage inlet channel in the water flow zone, and on the other hand, it can prevent sewage from entering the airflow zone and causing water splashing (the splashed water droplets are more easily sucked into the blower), thereby ensuring the actual water capacity of the sewage tank when it is lying flat.

[0019] Furthermore, the water flow zone is divided into a first chamber and a second chamber by a one-way valve assembly along the cross-sectional direction of the barrel. The first chamber is located at the first end of the barrel, and the second chamber is located at the second end. The one-way valve assembly controls the flow of water from the first chamber into the second chamber. This ensures that wastewater in the water flow zone can only enter the second chamber from the first chamber, effectively preventing the water level in the first chamber from becoming too high and thus preventing wastewater from entering the blower through the air outlet.

[0020] Furthermore, the upper end of the one-way valve assembly is provided with a siphon channel. The first siphon port of this siphon channel is located in the first chamber, and the second siphon port is located in the second chamber, with the height of the first siphon port being higher than that of the second siphon port. For ease of description, moving the sewage tank towards the first end of the tank in a horizontal position is considered forward, and moving it towards the second end of the tank is considered backward. In the first case: the sewage tank moves forward, and the water flows backward due to inertia. Therefore, the water flows from the first chamber to the second chamber. At this time, the one-way valve assembly opens, and the sewage enters the second chamber.

[0021] In the second state: the sewage tank moves backward, while the water flows forward due to inertia. Therefore, the water flows from the second chamber towards the first chamber. Because the one-way valve assembly is closed, sewage cannot enter the first chamber. Without the aforementioned siphon channel, the water level in the second chamber would rise higher and higher until it submerges in the airflow zone, causing airflow-driven water flow. However, by creating a siphon channel, this invention allows a small amount of sewage in both the first and second chambers to circulate between them, preventing the water level in the second chamber from becoming too high.

[0022] Furthermore, due to the different distances from the air outlet, the negative pressure in the airflow zone corresponding to the first chamber is greater than the negative pressure in the airflow zone corresponding to the second chamber. Therefore, if the water level in the second chamber is higher than the second siphon outlet, the wastewater in the second chamber will flow into the first chamber through the siphon channel under siphon action. Compared to ordinary straight holes, the siphon channel can better control the water level in the second chamber and has a faster water flow rate, thus better preventing the water level in the second chamber from becoming too high.

[0023] Furthermore, the one-way valve assembly includes a partition and a cover plate made of a soft material. The partition is positioned along the cross-sectional direction of the tank body within the water flow zone and is provided with guide holes. The cover plate is mounted on one side surface of the partition and located in the second chamber. The upper end of the cover plate is connected to the partition, and the cover plate can adhere to or detach from the partition under the action of water flow, thereby opening or closing the guide holes on the partition. Thus, when sewage flows from the first chamber to the second chamber, the water pressure pushes the cover plate, causing it to detach from the partition, opening the guide holes on the partition (i.e., opening the one-way valve assembly), and sewage enters the second chamber through the guide holes on the partition. Conversely, when water flows from the second chamber towards the first chamber, the water pressure causes the cover plate to adhere to the partition, closing the guide holes (i.e., closing the one-way valve assembly), preventing sewage from entering the first chamber through the guide holes.

[0024] Furthermore, the upper end of the partition plate on the surface of the second chamber is respectively covered with a siphon hood with an open bottom along the height direction of the partition plate, and each siphon hood and the partition plate respectively form the aforementioned siphon channel. The first siphon port of each siphon channel is respectively opened at the corresponding position of the partition plate covered by the siphon hood, and the second siphon port of each siphon channel is the opening at the bottom of each siphon hood. This simplifies the siphon channel structure and allows for better arrangement of each siphon channel on the one-way valve assembly.

[0025] Furthermore, the separation section includes a separation plate extending along the longitudinal section of the barrel, a separation cover, and a sludge inlet pipe. The sludge inlet pipe is fixed to one end of the upper surface of the separation plate along the length of the barrel and adjacent to the first end of the barrel. One end of the sludge inlet pipe is the aforementioned sludge inlet. The upper separation cover is fitted over the other end of the upper surface of the separation plate and is arranged along the width of the barrel, with one end of the separation cover facing the second end of the barrel.

[0026] Furthermore, the aforementioned separation hood is vertically partitioned with two partition plates spaced apart along the width of the barrel, and each partition plate extends along the length of the barrel. The two partition plates divide the inner cavity of the separation hood into a central channel located in the middle and airflow channels located on both sides of the central channel. A connection port located in the center of the central channel is opened at the other end of the separation hood, and air outlet ports corresponding to each airflow channel are opened on both sides of the connection port. The other end of the aforementioned sewage inlet pipe is connected to the connection port, so that the inner cavity of the sewage inlet pipe is connected to the aforementioned central channel to form the sewage inlet channel. The opening of the separation hood is divided into a sewage outlet corresponding to the sewage inlet channel and an air inlet port corresponding to each airflow channel. This makes the internal structure of the separation section simple, allowing for better placement of the sewage inlet channel in the separation section, and the design of the separation hood enables better separation of gaseous waste and solid-liquid waste at the sewage outlet.

[0027] Furthermore, the baffle is fixed to the lower surface of the separation plate, ensuring its stable installation. The separation plate has return ports on both sides of the inlet pipe, dividing it into a first plate and a second plate along the length of the tank. The side edges of each plate extend vertically downwards to form baffles. This allows a small amount of solid and liquid waste entering the airflow channel with the gaseous waste to fall back into the water flow area under its own gravity through the return ports. Additionally, the baffles provide a certain degree of wave suppression as the wastewater tank moves backwards, preventing splashing into the airflow area.

[0028] Furthermore, the air outlet is a hollow block, the inner cavity of which forms an air outlet chamber. The first end of the air outlet is fitted into the opening of the barrel body, and the outer end face of the first end extends along the cross-sectional direction of the barrel body.

[0029] One end of the aforementioned separation plate is fixed in the center to the outer end face of the air outlet, and the first end of the air outlet has a suction port located on the separation plate and in the air outlet chamber. There are two suction ports, which correspond one-to-one with the airflow channels. Each suction port is directly opposite the air outlet port of the corresponding airflow channel along the length of the barrel.

[0030] The second end of the aforementioned air outlet is located outside the barrel and has an air outlet located in the aforementioned air outlet chamber. This allows the gaseous waste entering each airflow channel to flow more effectively to the air outlet under the action of negative pressure suction.

[0031] Furthermore, each of the suction ports is respectively arranged opposite to the air outlet along the length of the barrel and staggered vertically along the width of the barrel, and the height of the air outlet is higher than the inner bottom surface of the air outlet chamber. In this way, while ensuring suction power for gaseous waste, solid and liquid waste can be prevented from entering the air outlet (even if it enters the air outlet chamber, it will fall under its own gravity and avoid entering the air outlet).

[0032] Furthermore, a filter basket for filtering water and collecting solid waste is detachably installed on the opening of the separation hood. This allows for the collection of solid waste through the filter basket, achieving the separation of sewage and solid waste.

[0033] Furthermore, the filter basket includes a basket body and a basket lid. The basket body is hood-shaped and has a first opening and a second opening that are interconnected. The first opening is detachably connected to the opening of the separation cover, while the second opening is downward-facing in a flat position. The basket lid can be closed onto the second opening of the basket body, and one end of the basket lid is rotatably connected to the bottom of the separation plate, while the other end is rotatably connected to the basket body. This facilitates the assembly and disassembly of the filter basket, making it easier for users to empty the solid waste collected in the filter basket.

[0034] The technical solution adopted to further solve the fifth technical problem mentioned above is: a cleaning machine, characterized in that it includes a sewage tank for the cleaning machine as described above.

[0035] Compared with the prior art, the advantages of the present invention are: the sewage inlet channel is set in the separation part of the separation seat, so there is no need to set up a separate pipe for garbage to enter in the barrel. This makes the sewage tank of the present invention consist of only two parts (separation seat and barrel), with a simple internal structure and convenient cleaning of the inside of the barrel.

[0036] Furthermore, airflow channels are set on both sides of the aforementioned sewage inlet channel, and the air inlet ports of each airflow channel are arranged in parallel with the aforementioned sewage outlets, while the air outlet ports are fluidly connected to the aforementioned sewage outlets. In this way, the gaseous waste at the sewage outlet can be turned under the action of negative pressure suction and enter the airflow channels on both sides respectively, and be discharged through the air outlets, while solid and liquid waste will fall into the inner cavity of the barrel, thereby achieving the separation of gaseous waste and solid and liquid waste.

[0048] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0049] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this invention can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0050] like Figures 1-11 As shown, this is a preferred embodiment of the wastewater tank in the present invention. The wastewater tank is suitable for a cleaning machine and can be detachably mounted on the body of the cleaning machine (not shown). In this embodiment, the cleaning machine refers to a floor scrubber. Furthermore, since the floor scrubber has both upright and horizontal operating states, the wastewater tank in the present invention also has both upright and horizontal operating states. Embodiments 1 and 2 describe the specific structure of the wastewater tank in the horizontal operating state.

[0051] Example 1:

[0052] like Figures 1-7 As shown, a wastewater tank for a cleaning machine includes a tank body 1, a separation seat 2, an air outlet 2202, a wastewater inlet channel 211, and an airflow channel 212. The tank body 1 has an open first end, and the separation seat 2 is sealed within the opening of the tank body 1. The separation seat 2 includes a separation portion 21 located within the tank body 1 and an air outlet 22 exposed outside the tank body 1. The air outlet 2202 is located on the air outlet 22 of the separation seat 2 and communicates with the inner cavity of the tank body 1.

[0053] Furthermore, the aforementioned sewage inlet channel 211 is disposed in the separation section 21 of the separation seat 2 along the length direction of the barrel body 1. One end opens as a sewage inlet 2111 and bends to one side to open onto the side wall of the barrel body 1, while the other end opens as a sewage outlet 2112 facing the second end of the barrel body 1. Airflow channels 212 are disposed in the separation section 21 and are respectively disposed on both sides of the sewage inlet channel 211 along the width direction of the barrel body 1. Moreover, each of the aforementioned airflow channels 212 extends along the length direction of the barrel body 1, and the air inlet port 2121 of each airflow channel 212 is arranged side by side with the sewage outlet 2112, while the air outlet port 2122 is in fluid communication with the air outlet 2202.

[0054] As can be seen from the above, in this invention, the sewage inlet channel 211 is located in the separation section 21 of the separation seat 2. This eliminates the need for a separate pipe for garbage to enter the tank 1, making the sewage tank of this invention consist of only two parts (separation seat 2 and tank 1), with a simple internal structure and convenient cleaning of the inside of the tank 1. In addition, airflow channels 212 are located on both sides of the sewage inlet channel 211, and the air inlet port 2121 of each airflow channel 212 is arranged parallel to the sewage outlet 2112, while the air outlet port 2122 is fluidly connected to the air outlet 2202. In this way, the gaseous garbage at the sewage outlet 2112 can be turned under the negative pressure suction and enter the airflow channels 212 on both sides, and be discharged through the air outlet 2202, while the solid and liquid garbage will fall into the inner cavity of the tank 1, thereby achieving the separation of gaseous garbage and solid and liquid garbage.

[0055] Furthermore, the aforementioned separation section 21 extends along the longitudinal section of the tank body 1, dividing the inner cavity of the tank body 1 into an airflow zone 101 and a water flow zone 102 when the tank body 1 is lying flat. The aforementioned sewage inlet channel 211 and each airflow channel 212 are located within the airflow zone 101. This design prevents sewage from the water flow zone 102 from entering the sewage inlet channel 211, and also prevents sewage from entering the airflow zone 101, which would cause water splashing (splashed water droplets are more easily sucked into the blower), thus ensuring the actual water capacity of the sewage tank when the tank is lying flat.

[0056] Furthermore, a one-way valve assembly 4 is provided along the cross-sectional direction of the barrel 1 in the aforementioned water flow zone 102, dividing the water flow zone 102 into a first chamber 1021 and a second chamber 1022. The first chamber 1021 is located at the first end of the barrel 1, and the second chamber 1022 is located at the second end of the barrel 1. The one-way valve assembly 4 controls the flow of water from the first chamber 1021 into the second chamber 1022. That is, sewage in the water flow zone 102 can only enter the second chamber 1022 from the first chamber 1021, thereby effectively preventing the water level in the first chamber 1021 from becoming too high, and thus preventing sewage from entering the blower through the air outlet 2202.

[0057] Furthermore, preferably, the upper end of the aforementioned one-way valve assembly 4 is provided with a siphon channel 43. The first siphon port 431 of the siphon channel 43 is located in the first chamber 1021, while the second siphon port 432 is located in the second chamber 1022, and the height of the first siphon port 431 is higher than that of the second siphon port 432. For ease of description, moving the sewage tank towards the first end of the tank body 1 in a horizontal position is forward, and moving it towards the second end of the tank body 1 is backward. In the first case: the sewage tank moves forward, and the water flows backward under the action of inertia. Therefore, the water flows from the first chamber 1021 towards the second chamber 1022. At this time, the one-way valve assembly 4 opens, and the sewage enters the second chamber 1022.

[0058] In the second state: the sewage tank moves backward, and the water flows forward due to inertia. Therefore, the water flows from the second chamber 1022 towards the first chamber 1021. Since the one-way valve assembly 4 is closed, sewage cannot enter the first chamber 1021. If the siphon channel 43 is not provided, the water level in the second chamber 1022 will rise higher and higher until it submerges in the airflow zone 101, causing the airflow to blow water. In this invention, by providing the siphon channel 43, a small amount of sewage in the first chamber 1021 and the second chamber 1022 can circulate between them through the siphon channel 43, preventing the water level in the second chamber 1022 from becoming too high. Furthermore, due to the different distances between the air outlet 2202 and the air outlet, the negative pressure in the airflow zone 101 corresponding to the first chamber 1021 is greater than the negative pressure in the airflow zone 101 corresponding to the second chamber 1022. Therefore, if the water level in the second chamber 1022 is higher than the second siphon port 432, the wastewater in the second chamber 1022 will flow into the first chamber 1021 through the siphon channel 43 under siphon action. Compared to a regular straight orifice, the siphon channel 43 can better control the water level in the second chamber 1022 and has a faster water flow rate, thus better preventing the water level in the second chamber 1022 from becoming too high.

[0059] The specific structure of the aforementioned one-way valve assembly 4 can be implemented in various ways. In this embodiment, preferably, the one-way valve assembly 4 includes a partition 41 and a cover plate 42 made of soft material. The partition 41 is disposed in the water flow zone 102 along the cross-sectional direction of the barrel 1 and is provided with guide holes 410. The cover plate 42 is installed on one side surface of the partition 41 and is located in the second chamber 1022. The upper end of the cover plate 42 is connected to the partition 41, and the cover plate 42 can adhere to or detach from the partition 41 under the action of water flow to open or close the guide holes 410 on the partition 41. In this way, when the sewage in the first chamber 1021 flows to the second chamber 1022, the water flow pressure pushes the cover plate 42 to detach from the partition 41, and the guide holes 410 on the partition 41 open (i.e., the one-way valve assembly 4 opens). The sewage enters the second chamber 1022 through the guide holes 410 on the partition 41. When the water flows from the second chamber 1022 toward the first chamber 1021, the water pressure causes the cover plate 42 to adhere to the partition plate 41, thereby closing each guide hole 410 (i.e., closing the one-way valve assembly 4), and the sewage cannot enter the first chamber 1021 through the guide hole 410.

[0060] Furthermore, specifically, the upper end of the partition 41 is covered with a siphon shroud 430 with an open bottom on the surface of the second chamber 1022 along the height direction of the partition 41, and each siphon shroud 430 and the partition 41 respectively form the siphon channel 43. The first siphon port 431 of each siphon channel 43 is opened at the corresponding position of the partition 41 covered by each siphon shroud 430, and the second siphon port 432 of each siphon channel 43 is the opening at the bottom of each siphon shroud 430. This simplifies the structure of the siphon channel 43 and allows for better arrangement of each siphon channel 43 on the one-way valve assembly 4.

[0061] Furthermore, the aforementioned separation section 21 includes a separation plate 5, a separation cover 7, and a sludge inlet pipe 6 extending along the longitudinal section direction of the barrel body 1. The sludge inlet pipe 6 is fixed to one end of the upper surface of the separation plate 5 along the length direction of the barrel body 1 and adjacent to the first end of the barrel body 1; one end of the sludge inlet pipe 6 is the aforementioned sludge inlet 2111. The upper separation cover 7 is fitted over the other end of the upper surface of the separation plate 5 and is arranged along the width direction of the barrel body 1, with the opening of one end of the separation cover 7 facing the second end of the barrel body 1. Furthermore, the separation cover 7 is vertically partitioned with two partition plates 71 spaced apart along the width direction of the barrel body 1, each partition plate 71 extending along the length direction of the barrel body 1. The two partition plates 71 divide the inner cavity of the separation cover 7 into a central channel 70 located in the middle and airflow channels 212 located on both sides of the central channel 70. The other end of the separation hood 7 has a central connection port (not shown) located in the central channel 70, and on both sides of this connection port are air outlet ports 2122 corresponding to each airflow channel 212. The other end of the aforementioned sewage inlet pipe 6 is connected to the aforementioned connection port, so that the inner cavity of the sewage inlet pipe 6 is connected to the aforementioned central channel 70 to form the sewage inlet channel 211. The opening of the separation hood 7 is divided into sewage outlet ports 2112 corresponding to the sewage inlet channel 211 and air inlet ports 2121 corresponding to each airflow channel 212. This makes the internal structure of the separation section 21 simple. On the one hand, it can better set the sewage inlet channel 211 on the separation section 21. On the other hand, the design of the separation hood 7 can better separate gaseous waste from solid and liquid waste at the sewage outlet ports 2112.

[0062] Furthermore, the aforementioned baffle 41 is fixed to the lower surface of the aforementioned separation plate 5 (in this embodiment, the two are an integral piece, thus ensuring the simplicity of the sewage tank structure), thereby ensuring the stable installation of the baffle 41. The separation plate 5 is divided into a first plate 51 and a second plate 52 along the length of the tank body 1 by backflow ports 53 opened on both sides of the aforementioned sewage inlet pipe 6, and the two side edges of each plate extend vertically downwards to form baffles 54. In this way, on the one hand, a small amount of solid and liquid waste entering the airflow channel 212 with the gaseous waste can fall back into the water flow zone 102 under its own gravity through the backflow ports 53; on the other hand, the baffles 54 can play a certain wave-suppressing role when the sewage tank is moving backwards, preventing waves from splashing into the airflow zone 101.

[0063] Furthermore, the aforementioned air outlet 22 is a hollow block, with its inner cavity forming an air outlet chamber 220. The first end of the air outlet 22 is embedded in the opening of the tank 1, and the outer end face of this end extends along the cross-sectional direction of the tank 1. Thus, when the sewage tank moves backward, the portion of the outer end face located in the first chamber 1021 can act as a wave-prevention mechanism. One end of the aforementioned separation plate 5 is centrally fixed to the aforementioned outer end face of the air outlet 22, and the end wall of the first end of the air outlet 22 has a suction port 2201 located on the separation plate 5 and in the aforementioned air outlet chamber 220. There are two suction ports 2201, each corresponding to one of the aforementioned airflow channels 212. Each suction port 2201 is directly opposite the air outlet port 2122 of the corresponding airflow channel 212 along the length direction of the tank 1. The second end of the aforementioned air outlet 22 is located outside the tank 1 and has the aforementioned air outlet 2202 located in the aforementioned air outlet chamber 220. This allows the gaseous waste entering each airflow channel 212 to flow more effectively to the outlet 2202 under the action of negative pressure suction.

[0064] Preferably, each of the above-mentioned suction ports 2201 is respectively arranged opposite to the above-mentioned air outlets 2202 along the length direction of the barrel body 1, and is staggered vertically along the width direction of the barrel body 1, and the height of the air outlets 2202 is higher than the inner bottom surface of the air outlet chamber 220. In this way, while ensuring the suction force for gaseous waste, it can prevent solid and liquid waste from entering the air outlets 2202 (even if it enters the air outlet chamber 220, it will fall under its own gravity and avoid entering the air outlets 2202).

[0065] Example 2:

[0066] like Figures 8-11 As shown, unlike Embodiment 1, in this embodiment, a filter basket 3 for filtering water and collecting solid waste is detachably installed on the opening of the separation hood 7. This allows for the collection of solid waste through the filter basket 3, achieving the separation of sewage and solid waste.

[0067] Furthermore, the aforementioned filter basket 3 includes a basket body 31 and a basket cover 32.
