[0002] A cleaning robot is a cleaning device capable of autonomously completing cleaning tasks, designed to replace traditional manual cleaning, improve cleaning efficiency, and reduce labor intensity. Cleaning robots in this technology have both sweeping and vacuuming functions, with the vacuuming function relying on negative pressure generated within the robot's dust collection container by an internal fan. However, this technology suffers from poor separation of gas-liquid-solid mixtures drawn into the cleaning device. Utility Model Content

[0018] In some embodiments, the waste collection container further includes a waste inlet pipe, the waste inlet pipe having the waste inlet formed inside the waste inlet pipe, one end of the waste inlet pipe extending horizontally into the inner cavity along the first direction, and the end of the waste inlet pipe located in the inner cavity being spaced apart from the guide baffle.

[0019] Wherein, one end of the sewage inlet pipe located in the inner cavity extends in the first direction between the first bend and the second bend.

[0020] In some embodiments, the distance between the air outlet and the upper edge of the windbreak section away from the receiving area in the first direction is greater than the distance between the air outlet and the lower edge of the windbreak section near the receiving area in the first direction.

[0021] And / or, the end of the partition near the air outlet in the first direction is located on the upper side of the end of the partition near the sewage inlet in the first direction.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0046] This application provides a cleaning device, which can be a robot vacuum cleaner, a vacuum and mop combo machine, a sweeping vehicle, or other cleaning equipment. The cleaning device can generate negative pressure to draw in the cleaned object, including liquids or solids.

[0047] The cleaning equipment provided in this application includes a waste collection container. The waste collection container is used to separate the solid-liquid mixture from the gas in the airflow in cleaning equipment such as a robot vacuum cleaner or a sweeper-mop. The waste collection container is used for the airflow generated when the cleaning equipment sucks up the cleaned items to pass through, and to separate the solids or liquids carried in the airflow from the airflow, thereby realizing the collection of garbage and wastewater.

[0048] Please refer to the following: Figures 1 to 7 The waste collection container 100 provided in the embodiments of this application will now be described. It should be noted that the first direction in the following text is the x-direction shown in the figure, the second direction in the following text is the y-direction shown in the figure, and the height direction in the following text is the z-direction shown in the figure.

[0049] The waste collection container 100 provided in this application embodiment includes a body 10, the body 10 having an inner cavity 11, the inner cavity 11 having an air outlet 13 and a waste inlet 12 arranged along a first direction x, the waste inlet 12 extending horizontally for allowing airflow to enter the inner cavity 11 horizontally, and a receiving area 111 is formed in the portion of the inner cavity 11 below the waste inlet 12, so that solids and / or liquids in the airflow enter the receiving area 111 by their own weight.

[0050] In some embodiments, such as Figure 1 , Figure 4 and Figure 7As shown, the first direction x extends horizontally so that the air outlet 13 and the sewage inlet 12 are arranged horizontally.

[0051] In other embodiments (not shown in the figures), the first direction x has an angle with the horizontal direction, such that the air outlet 13 is above the sewage inlet 12 or below the sewage inlet 12.

[0052] like Figures 1 to 7 As shown, the body 10 has a hollow structure, and an inner cavity 11 is formed on the inner side of the body 10. One end of the inner cavity 11 in the first direction x has a sewage inlet 12, which penetrates the inner wall and the outer wall of the body 10. The sewage inlet 12 connects the inner cavity 11 with the outer side of the body 10 so that airflow can enter the inner cavity 11 from the sewage inlet 12. The other end of the inner cavity 11 in the first direction x has an air outlet 13, which penetrates the inner wall and the outer wall of the body 10. The air outlet 13 connects the inner cavity 11 with the outer side of the body 10 so that the gas in the inner cavity 11 can be discharged from the air outlet 13.

[0053] The distance between the air outlet 13 and the upper end of the inner cavity 11 is less than the distance between the air outlet 13 and the lower end of the inner cavity 11, and the distance between the sewage inlet 12 and the upper end of the inner cavity 11 is less than the distance between the sewage inlet 12 and the lower end of the inner cavity 11. A receiving area 111 is formed in the lower part of the inner cavity 11. The receiving area 111 is used to receive solid and liquid waste to prevent it from being discharged with the gas and to ensure the separation effect.

[0054] The beneficial effects of the waste collection container 100 provided in this application embodiment are as follows: the waste collection container 100 provided in this application embodiment has an inlet 12 and an outlet 13 arranged in a horizontal direction, and the inlet 12 is located on the upper side of the accommodating area 111. When the airflow enters the inner cavity 11 from the inlet 12, it flows in a horizontal direction, and the solid-liquid mixture in the airflow accumulates in the accommodating area 111 under the action of gravity, so as to achieve the separation of airflow. Thus, the waste collection container 100 provided in this application has the advantage of better separation of solid and liquid in the gas-liquid-solid mixture entering the waste collection container 100 from the inlet 12.

[0055] In some embodiments provided in this application, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the sewage inlet 12 and the air outlet 13 are connected by a first air duct 101 and a second air duct 102 arranged in parallel.

[0056] Among them, the air outlet end of the first air duct 101 and the air outlet end of the second air duct 102 are related to Figure 2 The xOz planes shown are arranged opposite each other, with the air inlet end of the first air duct 101 and the air inlet end of the second air duct 102 relative to each other. Figure 2The xOz planes shown are arranged opposite each other.

[0057] like Figure 3 As shown, the airflow flows from the inlet 12 to the inner cavity 11 and is then divided into two streams of airflow in the inner cavity 11. The two streams of airflow flow along the first air duct 101 and the second air duct 102 to the outlet end, respectively.

[0058] In some embodiments, such as Figure 2 and Figure 3 As shown, the air outlet of the first air duct 101 and the air outlet of the second air duct 102 are related to Figure 2 The xOz planes shown are arranged opposite each other so that the airflow from the first duct 101 and the airflow from the second duct 102 are arranged along... Figure 3 As shown, the airflow in the second direction y flows relative to each other, and the airflow from the first air duct 101 and the airflow from the second air duct 102 collide with each other, so that the motion inertia of the solid or liquid in the airflow from one of the first air duct 101 and the second air duct 102 is canceled out by the solid or liquid in the airflow from the other of the first air duct 101 and the second air duct 102.

[0059] Therefore, between the air outlet of the first air duct 101 and the air outlet of the second air duct 102, the solid or liquid in the airflow is only subject to gravity and settles at the bottom of the inner cavity 11, thereby separating the solid or liquid in the airflow.

[0060] like Figure 2 and Figure 3 As shown, the air inlet end of the first air duct 101 and the air inlet end of the second air duct 102 are related to Figure 2 The xOz planes shown are arranged opposite each other so that the airflow entering the inner cavity 11 is divided into two streams along the second direction y and enters the first air duct 101 and the second air duct 102 respectively. When the airflow in the inner cavity 11 is divided into two streams along the second direction y, the solid or liquid in the airflow is subjected to negative pressure force from the first air duct 101 and negative pressure force from the second air duct 102. The negative pressure force from the first air duct 101 on the solid or liquid in the airflow extends along one side of the second direction y, and the negative pressure force from the second air duct 102 on the solid or liquid in the airflow extends along the other side of the second direction y.

[0061] Therefore, the forces acting on the solids or liquids in the airflow in the second direction y cancel each other out. It can be considered that the solids and liquids in the airflow are mainly subject to gravity and settle at the bottom of the inner cavity 11, thereby separating the solids or liquids in the airflow.

[0062] In other embodiments (not shown in the figures), the air outlet of the first air duct 101 and the air outlet of the second air duct 102 are related... Figure 2The xOz planes shown are arranged opposite each other, but the air inlet of the first air duct 101 is not aligned with the air inlet of the second air duct 102. Figure 2 The xOz planes shown are arranged opposite each other.

[0063] In other embodiments, such as Figure 5 and Figure 6 As shown, the air inlet end of the first air duct 101 and the air inlet end of the second air duct 102 are related to Figure 5 The xOz planes shown are arranged opposite each other, but the air outlet of the first air duct 101 is not arranged opposite to the air outlet of the second air duct 102.

[0064] In some embodiments provided in this application, the waste collection container 100 further includes a guide baffle 30, which is disposed in the inner cavity 11. At least a portion of the guide baffle 30 is disposed between the waste inlet 12 and the air outlet 13. The guide baffle 30 is spaced apart from the inner wall of the body 10 on both sides in the second direction y. The second direction y is parallel to the horizontal direction and intersects the first direction x. One side of the guide baffle 30 in the second direction y forms the air inlet end of the first air duct 101, and the other side of the guide baffle 30 in the second direction y forms the air inlet end of the second air duct 102.

[0065] Guide baffle 30 about Figure 2 and Figure 5 The xOz plane shown is symmetrically arranged. The airflow entering the inner cavity 11 from the sewage inlet 12 passes around the guide baffle 30 and then enters the first air duct 101 or the second air duct 102 from both sides of the guide baffle 30 in the second direction y.

[0066] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the guide baffle 30 is disposed in the inner cavity 11 and fixed to the inner wall of the body 10. The guide baffle 30 is disposed on the side of the inlet 12 facing the outlet 13. When the airflow enters the inner cavity 11 from the inlet 12, the airflow impacts the surface of the guide baffle 30. The guide baffle 30 guides the airflow to flow along its surface, so that the airflow passes around the guide baffle 30 from both sides in the direction shown in the figure and enters the first air duct 101 and the second air duct 102 respectively.

[0067] Therefore, the guide baffle 30 is located between the sewage inlet 12 and the air outlet 13, which effectively extends the airflow path and increases the tortuosity of the airflow path from the sewage inlet 12 to the air outlet 13. This guides the solid-liquid mixture in the airflow to collide with each other or with the sewage collection container 100 and fall into the holding area 111, thereby improving the separation effect of the sewage collection container 100 on the airflow provided in this embodiment of the application.

[0068] In some embodiments provided in this application, such as Figure 4 and Figure 7 As shown, the angle between the guide baffle 30 and the horizontal direction is greater than or equal to 60°, and part of the guide baffle 30 is located between one end of the sewage inlet pipe 20 located in the air outlet 13 and the inner cavity 11.

[0069] In some embodiments, such as Figure 4 and Figure 7 As shown, the guide baffle 30 is arranged almost vertically. The airflow entering the inner cavity 11 from the sewage inlet 12 flows in the first horizontal direction x, so that the guide baffle 30 and the airflow entering the inner cavity 11 from the sewage inlet pipe 20 form a large angle, increasing the probability of collision between liquid and solid in the airflow and the guide baffle 30.

[0070] In other embodiments, the guide baffle 30 extends in a vertical direction.

[0071] In some embodiments provided in this application, the waste collection container 100 further includes a partition 40, which is disposed on the side of the guide baffle 30 away from the waste inlet pipe 20. The partition 40 is connected between the lower edge of the guide baffle 30 and the inner wall of the body 10, and the angle between the partition 40 and the horizontal direction is less than 30°.

[0072] In some embodiments, such as Figure 4 and Figure 7 As shown, the partition 40 is arranged almost horizontally. The partition 40 is located on the side of the guide baffle 30 away from the sewage inlet 12 in the first direction x. The partition 40 is located between the air outlet 13 and the guide baffle 30 in the first direction x, and the partition 40 is located below the guide baffle 30 and the air outlet 13, so that the airflow entering the inner cavity 11 from the sewage inlet 12 passes through the upper side of the partition 40 after being disturbed by the guide baffle 30 and enters the air outlet 13.

[0073] Thus, on the one hand, when the airflow passes over the upper side of the partition 40, the liquid and solid particles carried in the airflow settle on the upper side of the partition 40 due to gravity. The liquid and solid particles on the upper side of the partition 40 can fall into the accommodating area 111 at the bottom of the inner cavity 11 along the inclined surface of the partition 40. On the other hand, the partition 40 isolates the air outlet 13 from the accommodating area 111, preventing liquid or solid particles in the accommodating area 111 from entering the air outlet 13.

[0074] In other embodiments (not shown in the figures), the partition 40 extends in a horizontal direction.

[0075] In some embodiments provided in this application, such as Figures 2 to 7 As shown, the guide baffle 30 includes a windproof section 31, a first bending section 32, and a second bending section 33.

[0076] The windbreak section 31 is located between the air outlet 13 and the sewage inlet 12 at one end of the inner cavity 11, and the windbreak section 31 extends along the second direction y, which is a horizontal direction orthogonal to the first direction x.

[0077] The first bending segment 32 extends along the first direction x, and one end of the first bending segment 32 is connected to one end of the windbreak segment 31 in the second direction y. The other end of the first bending segment 32 extends along the first direction x toward the sewage inlet 12. The first bending segment 32 and the second bending segment 33 are arranged symmetrically about the xOz plane shown in the figure.

[0078] like Figure 2 and Figure 5 As shown, the windbreak section 31 extends along the second direction y and is located between the sewage inlet 12 and the air outlet 13. On the one hand, the airflow entering the inner cavity 11 from the sewage inlet pipe 20 can directly impact the surface of the windbreak section 31 facing the sewage inlet pipe 20, so that the liquid and solid particles in the airflow entering the inner cavity 11 settle into the accommodating area 111 on the lower side of the inner cavity 11. On the other hand, the airflow impacting the surface of the windbreak section 31 flows along the second direction y under the guidance of the windbreak section 31, with a part of the airflow flowing along one side of the second direction y and another part of the airflow flowing along the other side of the second direction y.

[0079] The first bend 32 and the second bend 33 are located at opposite ends of the windbreak section 31 in the second direction y, and both the first bend 32 and the second bend 33 bend towards the inlet 12 in the first direction x, so that the airflow entering the inner cavity 11 from the inlet pipe 20, after impacting the surface of the windbreak section 31, forms an airflow in the second direction y under the guidance of the first bend 32 and the second bend 33. Figure 3 or Figure 6 The airflow path shown increases the path length and tortuosity of the airflow from the inlet pipe 20 to the outlet 13, thereby effectively separating liquid and solid particles in the airflow.

[0080] In some embodiments provided in this application, such as Figures 1 to 7 As shown, the waste collection container 100 also includes a waste inlet pipe 20, which is located at the waste inlet 12. One end of the waste inlet pipe 20 extends along the first direction x toward the air outlet 13 into the inner cavity 11. The end of the waste inlet pipe 20 located in the inner cavity 11 is spaced apart from the guide baffle 30.

[0081] like Figures 1 to 7 As shown, the outer wall of the inlet pipe 20 is connected to the body 10. The inlet pipe 20 penetrates the body 10, connecting the outer side of the body 10 with the inner cavity 11 of the body 10. The inner wall of the inlet pipe 20 forms an inlet port 12. Airflow enters the inner cavity 11 along the inlet pipe 20. The inlet pipe 20 extends horizontally, and one end of the inlet pipe 20 located in the inner cavity 11 is arranged toward the guide baffle 30.

[0082] Thus, on the one hand, after the airflow is discharged from the inlet pipe 20 to the inner cavity 11, it impacts the surface of the guide baffle 30. By impacting the liquid and solid particles in the airflow onto the surface of the guide baffle 30, the flow rate of the liquid and solid mixture is slowed down, causing the solid-liquid mixture to settle faster under the action of gravity. On the other hand, the airflow needs to bypass the guide baffle 30 before it can reach the air outlet 13. This process further prolongs the airflow path, increases the settling time of the solid-liquid mixture, ensures better separation effect, and improves the separation effect of the waste collection container 100 provided in this application embodiment on solids and liquids in the airflow.

[0083] In addition, the airflow entering the inner cavity 11 through the sewage inlet pipe 20 flows horizontally, and the solid-liquid mixture in the airflow accumulates in the accommodating area 111 under the action of gravity, so as to achieve the separation of solids and liquids in the airflow. Thus, the sewage collection container 100 provided in this application has the advantage of better separation of solids and liquids in the gas-liquid-solid mixture entering the sewage collection container 100 from the sewage inlet 12.

[0084] In some embodiments provided in this application, such as Figures 2 to 7 As shown, one end of the sewage inlet pipe 20 located in the inner cavity 11 extends between the first bend section 32 and the second bend section 33.

[0085] like Figures 2 to 7 As shown, one end of the inlet pipe 20 extends into the inner cavity 11 and extends to the first bend section 32 on the side facing the second bend section 33 in the second direction y. Thus, reducing the distance between the inlet pipe 20 and the windbreak section 31 can increase the probability of liquid and solid particles carried in the airflow hitting the surface of the windbreak section 31, thereby improving the separation efficiency of liquid and solid particles in the gas-liquid-solid mixture.

[0086] In some embodiments provided in this application, such as Figure 4 and Figure 7 As shown, the upper edge of the guide baffle 30 is connected to the inner wall of the body 10, so that the inner wall of the body 10, the guide baffle 30, and the partition 40 together form a first air duct 101 and a second air duct 102. The first air duct 101 and the second air duct 102 are related to... Figure 2 and Figure 5 The xOz plane shown is symmetrically arranged.

[0087] The air inlet of the first air duct 101 is located on the side of the first bend section 32 away from the second bend section 33, the air inlet of the second air duct 102 is located on the side of the second bend section 33 away from the first bend section 32, and the air outlets of the first air duct 101 and the second air duct 102 are connected at the air outlet 13 on the side facing the inner cavity 11.

[0088] like Figure 4 and Figure 7 As shown, the upper edge of the guide baffle 30 is connected to the upper side of the inner wall of the body 10, the lower edge of the guide baffle 30 is connected to the side of the partition 40 facing the sewage inlet 12 in the first direction x, and the side of the partition 40 away from the sewage inlet 12 in the first direction x is connected to the inner wall of the body 10, thereby forming an air duct between the guide baffle 30, the partition 40 and the inner wall of the body 10, and the air duct is connected to the air outlet 13.

[0089] like Figures 2 to 7 As shown, a first air duct 101 and a second air inlet are provided between the guide baffle 30, the partition 40 and the inner wall of the body 10. The first air duct 101 and the second air duct 102 are independent air ducts, and the first air duct 101 is isolated from the receiving cavity, and the second air duct 102 is isolated from the receiving cavity, thereby preventing liquid or solid particles suspended in the receiving area from entering the first air duct 101 or the second air duct 102.

[0090] In some embodiments provided in this application (not shown in the figures), there are multiple first air ducts 101 and multiple second air ducts 102, and the second air ducts 102 are arranged in a one-to-one correspondence with the first air ducts 101.

[0091] In some embodiments, a plurality of first air ducts 101 are arranged along a third direction, and a plurality of second air ducts 102 are arranged along a third direction. In other embodiments, a plurality of first air ducts 101 are arranged along a second direction y, and a plurality of second air ducts 102 are arranged along a second direction y. In still other embodiments, a plurality of first air ducts 101 are arranged circumferentially around the axis of the sewage inlet 12, and a plurality of second air ducts 102 are arranged circumferentially around the axis of the sewage inlet 12.

[0092] Therefore, on the one hand, by setting multiple first air ducts 101 and second air ducts 102, the flow area between the sewage inlet 12 and the air outlet 13 is increased, thereby improving the ability of the sewage collection container 100 provided in this application embodiment to discharge airflow. On the other hand, when any one of the first air ducts 101 or the second air ducts 102 is blocked by solids in the airflow, the remaining first air ducts 101 or the second air ducts 102 can still allow airflow to pass through.

[0093] In some embodiments provided in this application, such as Figures 2 to 4 As shown, there is a single air outlet 13, so that the air inlet end of the first air duct 101 and the air inlet end of the second air duct 102 are connected, and the air outlet end of the first air duct 101 is connected to the air outlet end of the second air duct 102.

[0094] In the above embodiments, such as Figure 2 As shown, the first air duct 101 and the second air duct 102 are symmetrical about the xOz plane shown in the figure.

[0095] like Figure 2As shown, the shape of any position in the first air duct 101 is symmetrical to the shape of the corresponding position in the second air duct 102, and the axis of symmetry of the first air duct 101 and the second air duct 102 extends along the first direction x. The throttling area of ​​any position in the first air duct 101 is the same as the throttling area of ​​the corresponding position in the second air duct 102, and the path length of the airflow through the first air duct 101 is the same as the path length of the airflow through the second air duct 102.

[0096] Therefore, on the one hand, when the airflow in the inlet 12 is discharged to the outlet 13 through the first air duct 101 and the second air duct 102 respectively, the flow rate at the inlet end of the first air duct 101 and the flow rate at the inlet end of the second air duct 102 are the same. When the airflow in the inner cavity 11 is divided into two streams along the second direction y and enters the first air duct 101 and the second air duct 102 respectively, the solid or liquid in the airflow is subjected to the same negative pressure force from the first air duct 101 and the negative pressure force from the second air duct 102, and the magnitudes are the same and the directions are opposite. The forces on the solid or liquid in the airflow in the second direction y cancel each other out. It can be considered that the solid and liquid in the airflow are mainly subjected to gravity and settle at the bottom of the inner cavity 11, thereby separating the solid or liquid in the airflow.

[0097] On the other hand, when the airflow in the inlet 12 is discharged to the outlet 13 through the first air duct 101 and the second air duct 102 respectively, the flow rate at the outlet end of the first air duct 101 is the same as the flow rate at the outlet end of the second air duct 102, so that the airflow flowing out of the first air duct 101 and the airflow flowing out of the second air duct 102 are along the same path. Figure 3 In the second direction y shown, the airflows flow relative to each other and have the same flow rate. The airflows flowing out of the first air duct 101 and the airflows flowing out of the second air duct 102 collide with each other, causing the motion inertia of the solid or liquid in the airflow flowing out of one of the first air ducts 101 and the second air duct 102 to be canceled out by the solid or liquid in the airflow flowing out of the other of the first air ducts 101 and the second air duct 102.

[0098] Therefore, between the air outlet of the first air duct 101 and the air outlet of the second air duct 102, the solid or liquid in the airflow is only subject to gravity and settles at the bottom of the inner cavity 11, thereby separating the solid or liquid in the airflow.

[0099] In some embodiments provided in this application, such as Figures 5 to 7 As shown, there are multiple air outlets 13, including a first outlet 131 and a second outlet 132. The first outlet 131 is connected to the air outlet end of the first air duct 101, and the second outlet 132 is connected to the air outlet end of the second air duct 102.

[0100] like Figure 5As shown, the air inlet of the first air duct 101 and the air inlet of the second air duct 102 are connected in the inner cavity 11, but the air outlet of the first air duct 101 is not connected to the air outlet of the second air duct 102.

[0101] In the above embodiments, such as Figure 5 As shown, the first air duct 101 and the second air duct 102 are related to the passage Figure 5 The xOz plane shown is symmetric.

[0102] like Figure 6 As shown, the shape of any position in the first air duct 101 is symmetrical to the shape of the corresponding position in the second air duct 102, and the axis of symmetry of the first air duct 101 and the second air duct 102 extends along the first direction x. The throttling area of ​​any position in the first air duct 101 is the same as the throttling area of ​​the corresponding position in the second air duct 102, and the path length of the airflow through the first air duct 101 is the same as the path length of the airflow through the second air duct 102.

[0103] Therefore, when the airflow in the inlet 12 is discharged to the outlet 13 through the first air duct 101 and the second air duct 102 respectively, the flow rate at the inlet end of the first air duct 101 and the flow rate at the inlet end of the second air duct 102 are the same. When the airflow in the inner cavity 11 is divided into two streams along the second direction y and enters the first air duct 101 and the second air duct 102 respectively, the solid or liquid in the airflow is subjected to the same negative pressure force from the first air duct 101 and the negative pressure force from the second air duct 102, and the magnitudes are the same and the directions are opposite. The forces on the solid or liquid in the airflow in the second direction y cancel each other out. It can be considered that the solid and liquid in the airflow are mainly subjected to gravity and settle at the bottom of the inner cavity 11, thereby separating the solid or liquid in the airflow.

[0104] In some embodiments provided in this application, such as Figure 4 and Figure 7 As shown, the windbreak section 31 is arranged at an angle so that the distance between the air outlet 13 and the upper edge of the windbreak section 31 away from the receiving area 111 in the first direction x is greater than the distance between the air outlet 13 and the lower edge of the windbreak section 31 near the receiving area 111 in the first direction x.

[0105] like Figure 4 and Figure 7 As shown, the upper edge of the windbreak section 31 is close to the air outlet 13 in the first direction x, and the lower edge of the windbreak section 31 is far away from the air outlet 13 in the first direction x. Thus, when the airflow flows from the sewage pipe to the inner cavity 11 and impacts the surface of the windbreak section 31, the windbreak section 31 guides the airflow downward, which is beneficial for the settling of liquid and solid particles in the airflow.

[0106] In some embodiments provided in this application, such as Figure 4 and Figure 7As shown, the partition 40 is arranged at an angle so that the end of the partition 40 near the air outlet 13 in the first direction x is located on the upper side of the end of the partition 40 near the sewage inlet 12 in the first direction x.

[0107] like Figure 4 and Figure 7 As shown, the height of the baffle 40 gradually decreases along the direction from the air outlet 13 to the sewage inlet 12, so that the solids and liquids settled on the baffle 40 can flow back from the air inlet of the first air duct 101 and the air inlet of the second air duct 102 to the receiving area under the action of gravity, thus avoiding the solids and liquids settled on the baffle 40 from blocking the first air duct 101 and the second air duct 102.

[0108] In some embodiments provided in this application, the waste collection container 100 further includes a filter (not shown in the figure), the filter is disposed in the inner cavity 11, and the filter is located on the side of the air outlet 13 facing the inner cavity 11. The distance between the upper edge of the filter and the air outlet 13 in the first direction x is greater than the distance between the lower edge of the filter and the air outlet 13 in the first direction x.

[0109] The filter element is located at the air outlet 13 so that the airflow discharged from the inner cavity 11 through the air outlet 13 needs to pass through the filter element first to further filter out the liquid and solid carried in the airflow. The upper end of the filter element is far away from the air outlet 13, and the lower end of the filter element is close to the air outlet 13.

[0110] Therefore, when the airflow passes through the filter element, the filter element guides part of the airflow to flow downward along the surface of the filter element. On the one hand, this is conducive to the sedimentation of liquid and solid particles in the airflow. On the other hand, the airflow along the surface of the filter element can be used to blow away the liquid or solid particles deposited on the surface of the filter element facing the inner cavity 11, thus preventing the solids filtered out by the airflow from clogging the filter element.

[0111] In some embodiments, the filter element includes one or more of filter paper, sponge, and foam.
