Description

Technical Field

[0001] The present application relates to the field of cleaning devices, and in particular to a sewage tank and a cleaning device. Background Art

[0002] With the advancement of technology, floor scrubbers have become a commonly used cleaning device in households.

[0003] The floor scrubber in the related art includes components such as cleaning parts and a sewage recovery system; the sewage recovery system includes a sewage tank. The sewage tank is divided into a second cavity and a first cavity. The first cavity is used to collect sewage, and the second cavity is used to separate the airflow from sewage and solid impurities. A sewage flow port is generally provided between the second cavity and the first cavity, and the sewage flow port is connected through a one-way flat valve to reduce the probability of sewage backflow.

[0004] However, since the one-way flat-mouth valve does not close the sewage flow outlet, when the angle between the cleaning device and the ground is small, the sewage can easily flow back from the one-way flat-mouth valve into the second cavity and then be sucked into the fan, affecting the service life of the fan. Utility Model Content

[0005] The present application provides a sewage tank and a cleaning device, which are used to solve the problem that sewage in the sewage tank in the related art is easy to flow back.

[0006] On the one hand, the present application provides a sewage tank for a cleaning device, the sewage tank comprising a box body and a partition bracket, the box body having a receiving cavity, the receiving cavity having an air inlet and an air outlet;

[0007] The partition structure includes a partition bracket and a stopper; the partition bracket is arranged in the accommodating cavity, the partition bracket divides the accommodating cavity into a first cavity and a second cavity, the air inlet and the air outlet are both connected to the second cavity, and a sewage flow port connecting the second cavity and the first cavity is arranged on the partition bracket;

[0008] The stopper is arranged on the side of the partition bracket facing the first cavity and blocks at least part of the sewage flow outlet. A water-blocking cavity is provided between the stopper and the partition bracket. The water-blocking cavity has a drain outlet connected to the first cavity. When the cleaning device is in a non-upright working state, the height of the drain outlet is higher than the height of at least part of the sewage flow outlet.

[0009] According to the technical solution of this embodiment, a check piece is provided at the sewage flow outlet of the sewage tank, and the check piece can form a water-blocking cavity connected with the sewage flow outlet, and the water-blocking cavity has a drain outlet connected with the first cavity. When the cleaning device is in a non-upright working state, the height of the drain outlet is higher than the height of at least part of the sewage flow outlet to block the sewage, thereby reducing the risk of sewage backflow when the cleaning device is in a tilted state at a large angle.

[0010] In some embodiments, when the cleaning device is in a non-upright working state, the drainage outlet and the sewage flow outlet blocked by the stopper are respectively located on opposite sides of the air inlet in the vertical direction.

[0011] Such an arrangement can increase the height difference between the drain outlet and the sewage flow outlet, so that the first cavity has a larger sewage storage capacity.

[0012] In some embodiments, at least part of the stopper is spaced apart from the partition bracket to form a drain outlet between the stopper and the partition bracket. This arrangement makes the structure of the stopper simple, and the drain outlet is naturally formed by the structure of the stopper; or, the stopper is provided with a drain outlet, which connects the water-blocking cavity and the first cavity, so that the stopper can block part of the sewage flow outlet while ensuring smooth discharge of sewage, so as to reduce the probability of sewage backflow in the sewage tank when it is not in an upright working state.

[0013] In some embodiments, the sewage flow outlet includes a first sewage flow outlet, the stopper blocks the first sewage flow outlet, and when the cleaning device is in a non-upright working state, the height of the drain outlet is higher than the height of the first sewage flow outlet.

[0014] The above structure enables sewage to flow into the first cavity in a timely manner, thereby reducing the probability of sewage accumulating in the second cavity.

[0015] In some embodiments, the stopper includes a partition plate spaced apart from the partition bracket and a connecting portion provided on the partition plate, wherein the connecting portion is connected to at least one of the partition bracket and the inner wall of the box body to form a water blocking cavity.

[0016] In the above structure, the partition and the partition bracket are spaced apart to form a channel for sewage to flow into the first cavity. The connecting part can fix the partition so that the partition and the partition bracket can maintain a spaced apart arrangement so that sewage can flow smoothly into the first cavity.

[0017] In some embodiments, the connecting portion is disposed around the side of the partition and connected to the partition bracket, and the partition bracket, the connecting portion, and the partition form a water-blocking cavity.

[0018] In the above structure, the connecting part can connect the partition and the partition bracket, and can form a water-blocking cavity together with the partition bracket and the partition, so that the sewage can flow out from between the partition bracket and the partition. At the same time, when the cleaning device is in a non-upright working state, the stopper can also have a good stopping effect.

[0019] In some embodiments, the partition has a first side close to the sewage flow outlet and a second side away from the first sewage flow outlet, the connecting portion is surrounded by the first side of the partition, and the second side of the partition is spaced apart from the inner wall of the box to form a drain outlet between the edge of the second side of the partition and the inner wall of the box.

[0020] The above structure enables the position of the drain outlet to be higher than the position of the sewage flow outlet, thereby ensuring the stopping effect of the stopper.

[0021] In some embodiments, the connecting portion includes a surrounding plate, which includes a first side wall, a second side wall and a third side wall. The first side wall and the second side wall are spaced apart, and the third side wall connects the first end of the first side wall and the first end of the second side wall. The second end of the first side wall, the second end of the second side wall and the edge of the second side of the partition form a drainage outlet.

[0022] Such arrangement makes the stopper simple in structure and convenient in processing. In addition, the drain port has a large flow area, so that sewage can flow smoothly into the first cavity.

[0023] In some embodiments, the partition gradually tilts away from the partition bracket in the direction from the first sewage flow outlet to the drain outlet.

[0024] With such a configuration, when the cleaning device is in an upright state, the side of the partition close to the sewage flow outlet has a higher height, while the side close to the drain outlet has a lower height, so that the sewage can flow to the drain outlet under the diversion effect of the partition, so that the sewage can be discharged into the first cavity in time. When the cleaning device is in a non-upright working state, the inclination direction of the partition can push the sewage liquid surface away from the drain outlet, reducing the probability of sewage pouring into the drain outlet.

[0025] In some embodiments, heights of the first sidewall and the second sidewall gradually increase in a direction from the first end to the second end.

[0026] Such an arrangement enables the partition to be tilted in a predetermined tilting direction after the stopper is installed at the bottom of the partition bracket, without the need to laboriously adjust the tilting angle of the partition.

[0027] In some embodiments, the sewage tank further comprises a support plate disposed in the drain port, wherein the support plate is disposed on one of the partition bracket and the partition plate and contacts and cooperates with the other one.

[0028] Such an arrangement enables the stopper to be more stably installed at the bottom of the partition bracket to reduce the probability of the second end of the stopper fitting against the bottom end of the partition bracket, thereby ensuring the flow area of ​​the drain port and the tilt posture of the partition.

[0029] In some embodiments, the sewage flow outlet further includes a second sewage flow outlet, and when the cleaning device is in a non-upright working state, the height of the second sewage flow outlet is higher than or equal to the height of the drain outlet.

[0030] In the above structure, the sewage flow outlet includes a first sewage flow outlet and a second sewage flow outlet, so that the sewage can flow into the first cavity in time, reducing the probability of sewage accumulation in the second cavity.

[0031] In some embodiments, the box body includes an outer cylinder and an inner cylinder arranged in the outer cylinder, the outer cylinder forms a accommodating cavity, the first end of the inner cylinder extends to the bottom of the outer cylinder and is connected to the outside; the partition bracket includes a guide cylinder and a base frame located on the circumferential outside of the guide cylinder, the guide cylinder is connected to the second end of the inner cylinder, and the end of the guide cylinder away from the inner cylinder forms an air inlet of the sewage tank, the base frame divides the accommodating cavity into a first cavity and a second cavity, and the sewage flow hole is arranged on the base frame.

[0032] In the above structure, the airflow can carry solid waste and sewage into the inner cylinder, enter the guide cylinder from the inner cylinder, and then enter the second cavity from the air inlet. After air-water separation in the second cavity, it is discharged from the air outlet on the box cover.

[0033] In some embodiments, the partition bracket also includes a shielding structure arranged above the base frame, the shielding structure divides the second cavity into a sewage cavity and an airflow cavity, the air inlet and the sewage flow outlet are both connected to the sewage cavity, and the sewage cavity and the airflow cavity are connected through an airflow channel.

[0034] In the above structure, the shielding structure can improve the air-water separation effect in the second cavity, reduce the water content of the airflow entering the fan, and thus ensure the service life of the fan.

[0035] In some embodiments, the sewage flow outlet includes a first sewage flow outlet and a second sewage flow outlet, the stopper blocks the first sewage flow outlet, the base frame includes a first flat plate portion, a second flat plate portion, and a step portion arranged between the first flat plate portion and the second flat plate portion, the first sewage flow outlet is arranged on the first flat plate portion, and the second sewage flow outlet is arranged on the step portion.

[0036] In the above structure, the second sewage flow outlet can not only be used to circulate sewage, but also bears the function of balancing the air pressure of the first cavity and the second cavity and the function of circulating clean water when the sewage tank is self-cleaning. The second sewage flow outlet is arranged on the step portion so that the clean water can be more easily circulated when the sewage tank is self-cleaning.

[0037] On the other hand, the present application provides a cleaning device, comprising a cleaning assembly, a connecting rod and the above-mentioned sewage tank, wherein the cleaning assembly and the sewage tank are both connected to the connecting rod, and the cleaning assembly and the sewage tank are in communication. The cleaning device of the present application has the advantages of long service life and good user experience due to the sewage tank being provided.

[0038] The sewage tank provided by the present application includes a box body, a receiving cavity is provided in the box body, a partition bracket is provided in the receiving cavity, the partition bracket divides the receiving cavity into a first cavity and a second cavity, the second cavity is connected with the air inlet and the air outlet, the first cavity is used to collect sewage and impurities, and the second cavity is used to separate the airflow from the sewage, impurities, etc. A sewage flow port is also provided between the partition bracket and the inner wall of the box body, and sewage can flow from the second cavity into the first cavity through the sewage flow port. A stopper is provided on the side of the partition bracket facing the first cavity and blocks at least part of the sewage flow port, and a water blocking cavity is provided between the stopper and the partition bracket, and the water blocking cavity can connect the sewage flow port and the first cavity, so that the sewage can smoothly flow into the first cavity for collection.

[0039] During the use of the cleaning device, the cleaning component of the cleaning device is in contact with the ground, and the operator holds the handle of the cleaning device to control the movement of the cleaning component. If the cleaning device is in an upright state, the sewage tank is also in an upright state following the posture of the cleaning device, and at this time, the sewage can flow out from the sewage flow outlet, pass through the water blocking cavity, and enter the first cavity from the drain outlet to be collected.

[0040] When the cleaning device is in a non-upright working state, the sewage tank also follows the posture of the cleaning device and is in a non-upright working state. At this time, since the height of the drain outlet is higher than the height of at least part of the sewage flow outlet, the stopper can block the main sewage, making it difficult for the sewage to enter the sewage flow outlet, thereby preventing the sewage from flowing back.

[0053] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0054] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] In the related art, when a floor scrubber is cleaning the floor, the airflow generated by the fan will suck sewage and solid particles into a sewage tank, and the sewage, solid waste and airflow will be separated through the sewage tank.

[0056] Specifically, the sewage tank is generally divided into a second cavity and a first cavity. The bottom of the second cavity is connected to the first cavity through a one-way flat valve, and the top of the second cavity is connected to the air outlet of the sewage tank. When the floor scrubber is working, the airflow carries sewage and solid waste into the second cavity, the sewage flows into the first cavity through the one-way flat valve, and the solid waste remains in the second cavity. The airflow is discharged from the air outlet at the top of the second cavity, realizing the separation of liquid, solid and gas.

[0057] The one-way flat-mouth valve is a structure with a large inlet and a small outlet. When sewage flows from the large-mouth end to the small-mouth end, the sewage can flow out smoothly from the one-way flat-mouth valve. However, during the operation of the floor scrubber, the longer the working time, the more sewage will be collected in the sewage tank. Although the one-way flat-mouth valve can reduce the probability of sewage backflow to a certain extent, the small-mouth end still has a certain flow area, and the sewage is easy to flow back from the one-way flat-mouth valve into the second cavity. In particular, when the cleaning device cleans gaps such as the bottom of the sofa, it needs to be in a tilted state at a large angle. The sewage is more likely to flow back from the one-way flat-mouth valve, affecting the service life of the fan.

[0058] To solve the above-mentioned problem, the present application provides a sewage tank for a cleaning device, wherein a check member is arranged at the sewage flow outlet of the sewage tank, and the check member can form a water-blocking cavity connected with the sewage flow outlet, and the water-blocking cavity has a drain outlet connected with the first cavity. When the cleaning device is in a non-upright working state, the height of the drain outlet is higher than the height of at least part of the sewage flow outlet to block the sewage, thereby ensuring that the cleaning device has a lower risk of sewage backflow even when it is in a tilted state at a large angle.

[0059] The sewage tank provided in the embodiment of the present application is described below in conjunction with the accompanying drawings. It should be noted that the sewage tank provided in the embodiment of the present application can be applied to a cleaning device, and illustratively, the cleaning device can be a floor scrubber.

[0060] Figure 1 A cross-sectional view of a sewage tank provided in an embodiment of the present application, wherein: Figure 1 A schematic diagram of the structure of the sewage tank when the cleaning device is in an upright state is shown; Figure 2 A cross-sectional view of a sewage tank provided in an embodiment of the present application, wherein: Figure 2 The schematic diagram of the structure of the sewage tank when the cleaning device is in a non-upright working state is shown.

[0061] like Figure 1 and Figure 2 As shown, the sewage tank of this embodiment is used for a cleaning device, and the sewage tank includes a box body 100 and a partition foot bone, the box body 100 has a receiving cavity, and the receiving cavity has an air inlet 103 and an air outlet 104;

[0062] The partition structure includes a partition bracket 200 and a stopper 300; the partition bracket 200 is arranged in the accommodating cavity, and the partition bracket 200 divides the accommodating cavity into a first cavity 101 and a second cavity 102, the air inlet 103 and the air outlet 104 are both connected to the second cavity 102, and the partition bracket 200 is provided with a sewage flow port 214 connecting the second cavity 102 and the first cavity 101;

[0063] The stopper 300 is disposed on a side of the partition bracket 200 facing the first cavity 101 and blocks at least part of the sewage flow outlet 214. A water-blocking cavity 301 is provided between the stopper 300 and the partition bracket 200. The water-blocking cavity 301 has a drain outlet 302 connected to the first cavity 101. When the cleaning device is in a non-upright working state, the height of the drain outlet 302 is higher than the height of at least part of the sewage flow outlet 214.

[0064] Using the technical solution of this embodiment, the sewage tank 10 includes a box body 100, the box body 100 has a receiving cavity, and a partition bracket 200 is arranged in the receiving cavity. The partition bracket 200 divides the receiving cavity into a first cavity 101 and a second cavity 102. The second cavity 102 is connected with an air inlet 103 and an air outlet 104. The first cavity 101 is used to collect sewage and impurities, and the second cavity 102 is used to separate airflow from sewage, impurities, etc. A sewage flow port 214 is also arranged between the partition bracket 200 and the inner wall of the box body 100, and sewage can flow from the second cavity 102 into the first cavity 101 through the sewage flow port 214. The stopper 300 is disposed on the side of the partition bracket 200 facing the first cavity 101 and blocks at least part of the sewage flow outlet 214. A water-blocking cavity 301 is provided between the stopper 300 and the partition bracket 200. The water-blocking cavity 301 can connect the sewage flow outlet 214 and the first cavity 101, so that the sewage can smoothly flow into the first cavity 101 and be collected.

[0065] During the use of the cleaning device, the cleaning component of the cleaning device (such as a floor brush) is in contact with the ground, and the operator holds the handle of the cleaning device to control the movement of the cleaning component. If the cleaning device is in an upright state, the sewage tank 10 is also in an upright state following the posture of the cleaning device (such as Figure 1 As shown), at this time, the sewage can flow out from the sewage flow outlet 214, pass through the water blocking cavity 301, and then enter the first cavity 101 from the drain outlet 302 and collect.

[0066] When the cleaning device is in a non-upright working state, the sewage tank 10 also follows the posture of the cleaning device and is in a non-upright working state (such as Figure 2As shown), at this time, since the height of the drain outlet 302 is higher than the height of at least part of the sewage flow outlet 214, the stopper 300 can block the sewage, making it difficult for the sewage to enter the sewage flow outlet 214, thereby preventing the sewage from flowing back.

[0067] It should be noted that the "upright state" refers to the axis of the sewage tank being in the vertical direction, and the axis of the sewage tank is also perpendicular or approximately perpendicular to the ground (or other plane to be cleaned). The "non-upright working state" mainly refers to the state in which the cleaning device is in working state, and there is an angle between the axis of the sewage tank and the vertical direction. At this time, the cleaning device is tilted relative to the ground or other plane to be cleaned, and the angle between the axis of the sewage tank and the ground is less than 90°, so as to facilitate cleaning in a space with limited height or to facilitate reaching under furniture.

[0068] For example, Figure 2 As shown, when the accumulated amount of sewage in the first cavity 101 is between the first sewage liquid level a and the second sewage liquid level b, the sewage can be stopped by the stopper 300. It can be seen that when the cleaning device is in a non-upright working state, the greater the height difference between the drain port 302 and the sewage flow port 214, the greater the amount of sewage that can be stored in the first cavity 101.

[0069] In order to ensure the storage capacity of sewage in the first chamber 101, Figure 1 and Figure 2 As shown, in some embodiments, when the cleaning device is in a non-upright working state, the drainage port 302 and the sewage flow port 214 blocked by the stopper 300 are respectively located on opposite sides of the air inlet 103 in the vertical direction.

[0070] The above arrangement can increase the height difference between the drain port 302 and the sewage flow port 214, so that the first cavity 101 has a larger sewage storage capacity.

[0071] Figure 3 for Figure 2 An enlarged structural diagram of a sewage tank at C; Figure 4 This is a schematic diagram of the three-dimensional structure of the stopper of the sewage tank provided in an embodiment of the present application.

[0072] like Figures 1 to 3 As shown, in some embodiments, at least a portion of the stopper 300 is spaced apart from the partition bracket 200 to form a drain port 302 between the stopper 300 and the partition bracket 200 .

[0073] In the above structure, since the sewage flow opening 214 is arranged on the partition bracket 200, at least part of the stopper 300 is arranged at a distance from the partition bracket 200, so that the distance can form a sewage flow channel and a drain outlet 302. This arrangement makes the structure of the stopper 300 simple, and the drain outlet 302 is naturally formed by the structure of the stopper 300.

[0074] In other embodiments, a drain outlet may also be provided on the stopper, and the drain outlet connects the water-blocking cavity and the first cavity, so that the stopper can block part of the sewage flow outlet while ensuring smooth discharge of sewage, so as to reduce the probability of sewage backflow when the sewage tank is in a non-upright working state.

[0075] like Figures 1 to 3 As shown, in some embodiments, the sewage flow outlet 214 includes a first sewage flow outlet 2141, the stopper 300 blocks the first sewage flow outlet 2141, and when the cleaning device is in a non-upright working state, the height of the drain outlet 302 is higher than the height of the first sewage flow outlet 2141.

[0076] In addition, the sewage flow outlet 214 further includes a second sewage flow outlet 2142 . When the cleaning device is in a non-upright working state, the height of the second sewage flow outlet 2142 is higher than or equal to the height of the drain outlet 302 .

[0077] In the above structure, the sewage flow port 214 includes a first sewage flow port 2141 and a second sewage flow port 2142, so that the sewage can flow into the first cavity 101 in time, reducing the probability of sewage accumulation in the second cavity 102. At the same time, when the cleaning device is in a non-upright working state, the height of the first sewage flow port 2141 is the lowest, the drain port 302 is higher than the first sewage flow port 2141, and the second sewage flow port 2142 is higher than the drain port 302. Therefore, the stopper 300 only needs to block the first sewage flow port 2141 when the cleaning device is in a non-upright working state. Since the height of the second sewage flow port 2142 is higher, there is no need to stop the second sewage flow port 2142.

[0078] like Figures 1 to 4 As shown, in some embodiments, the stopper 300 includes a partition 310 spaced apart from the partition bracket 200 and a connecting portion disposed on the partition 310 connected to at least one of the partition bracket 200 and the inner wall of the box body 100 to form a water blocking cavity 301.

[0079] In the above structure, the partition 310 and the partition bracket 200 are spaced apart to form a channel for sewage to flow into the first cavity 101. The connecting portion can fix the partition 310 so that the partition 310 and the partition bracket 200 can maintain a spaced apart arrangement so that sewage can flow smoothly into the first cavity 101.

[0080] Specifically, Figure 3 and Figure 4 As shown, the connecting portion is disposed around the side of the partition 310 and connected to the partition bracket 200 , and the partition bracket 200 , the connecting portion, and the partition 310 form a water blocking cavity 301 .

[0081] In the above structure, the connecting part can connect the partition 310 and the partition bracket 200, and can form a water-blocking cavity 301 together with the partition bracket 200 and the partition 310, so that the sewage can flow out from between the partition bracket 200 and the partition 310. At the same time, when the cleaning device is in a non-upright working state, the stopper 300 can also have a good stopping effect.

[0082] In other embodiments not shown in the figures, the connection portion can also connect the partition to the inner wall of the box body, so that the partition and the partition bracket can also maintain a distance to facilitate the flow of sewage.

[0083] like Figures 1 to 4 As shown, in some embodiments, the partition 310 has a first side close to the sewage flow outlet 214 and a second side away from the first sewage flow outlet 2141, the connecting portion is surrounded by the first side of the partition 310, and the second side of the partition 310 is spaced apart from the inner wall of the box body 100 to form a drain outlet 302 between the edge of the second side of the partition 310 and the inner wall of the box body 100.

[0084] In the above structure, the connection part is located on the first side of the partition 310, and the first side is closer to the sewage flow outlet 214. When the cleaning device is in a non-upright working state, the partition 310 and the connection part contact with the sewage first, and together play a shielding effect on the sewage flow outlet 214. The drain port 302 is formed between the second side of the partition 310 and the inner wall of the box body 100, so that the position of the drain port 302 is higher than the position of the sewage flow outlet 214, ensuring the stopping effect of the stopper 300.

[0085] Specifically, Figure 4 As shown, in some embodiments, the connecting portion includes a surrounding plate 320, the surrounding plate 320 includes a first side wall 321, a second side wall 322 and a third side wall 323, the first side wall 321 and the second side wall 322 are spaced apart, the third side wall 323 connects the first end of the first side wall 321 and the first end of the second side wall 322, the second end of the first side wall 321, the second end of the second side wall 322 and the edge of the second side of the partition 310 form a drain outlet 302.

[0086] In this way, the stopper 300 has a simple structure and is easy to process. In addition, the second end of the first side wall 321, the second end of the second side wall 322 and the edge of the second side of the partition 310 form a drain port 302, so that the drain port 302 has a large flow area, so that sewage can flow smoothly into the first cavity 101.

[0087] In some embodiments, the partition 310 gradually tilts away from the partition bracket 200 in the direction from the first sewage flow opening 2141 to the drain opening 302 .

[0088] With such a configuration, when the cleaning device is in an upright state, the side of the partition 310 close to the sewage flow outlet 214 has a higher height, while the side close to the drain outlet 302 has a lower height, so that the sewage can flow toward the drain outlet 302 under the diversion effect of the partition 310, so that the sewage can be discharged into the first cavity 101 in time. When the cleaning device is in a non-upright working state, the inclination direction of the partition 310 can push the sewage liquid surface away from the drain outlet 302, reducing the probability of sewage pouring into the drain outlet 302.

[0089] Specifically, in some embodiments, the heights of the first side wall 321 and the second side wall 322 gradually increase in a direction from the first end to the second end.

[0090] Such an arrangement enables the partition plate 310 to be tilted in a predetermined tilting direction after the stopper 300 is installed at the bottom of the partition bracket 200 , without the need to laboriously adjust the tilting angle of the partition plate 310 .

[0091] In some embodiments, the sewage tank further includes a support plate 330 disposed in the drain port 302 . The support plate 330 is disposed on one of the partition bracket 200 and the partition plate 310 and contacts and cooperates with the other one.

[0092] Such an arrangement enables the stopper 300 to be more stably installed at the bottom of the partition bracket 200 to reduce the probability of the second end of the stopper 300 being in contact with the bottom end of the partition bracket 200 , thereby ensuring the flow area of ​​the drain port 302 and the tilt posture of the partition 310 .

[0093] For example, the support plate 330 may be disposed on the partition plate 310 and abut against the bottom of the partition bracket 200 .

[0094] Figure 5 A schematic diagram of the three-dimensional structure of the partition bracket of the sewage tank provided in an embodiment of the present application.

[0095] like Figures 1 to 5As shown, in some embodiments, the box body 100 includes an outer cylinder 110, an inner cylinder 120 arranged in the outer cylinder 110, and a box cover 130. The outer cylinder 110 and the box cover 130 form a accommodating cavity. The first end of the inner cylinder 120 extends to the bottom of the outer cylinder 110 and is connected to the outside; the partition bracket 200 includes a guide cylinder 220 and a base frame 210 located on the circumferential outside of the guide cylinder 220. The guide cylinder 220 is connected to the second end of the inner cylinder 120, and the end of the guide cylinder 220 away from the inner cylinder 120 forms an air inlet 103 of the sewage tank. The base frame 210 divides the accommodating cavity into a first cavity 101 and a second cavity 102, and the sewage flow hole is arranged on the base frame 210.

[0096] In the above structure, the airflow can carry solid waste and sewage into the inner cylinder 120, enter the guide cylinder 220 from the inner cylinder 120, and then enter the second cavity 102 from the air inlet 103. After air-water separation in the second cavity 102, it is discharged from the air outlet 104 on the box cover 130.

[0097] like Figures 1 to 5 As shown, in some embodiments, the partition bracket 200 also includes a shielding structure 230 arranged above the base frame 210, and the shielding structure 230 divides the second cavity 102 into a sewage cavity 1021 and an airflow cavity 1022. The air inlet 103 and the sewage flow port 214 are both connected to the sewage cavity 1021, and the sewage cavity 1021 and the airflow cavity 1022 are connected through the airflow channel 105.

[0098] In the above structure, the shielding structure 230 divides the second cavity 102 into a sewage cavity 1021 and an airflow cavity 1022. When the cleaning device is working, sewage and solid waste can be carried by the airflow into the sewage cavity 1021 first. Due to the obstruction of the shielding structure 230, the sewage and solid waste can be concentrated in the sewage cavity 1021, and enter the first cavity 101 from the sewage cavity 1021. After entering the sewage cavity 1021, the airflow enters the airflow cavity 1022 from the airflow channel 105 between the edge of the shielding structure 230 and the inner wall of the outer cylinder 110, and finally discharged from the air outlet 104.

[0099] like Figures 1 to 5 As shown, the sewage flow outlet 214 includes a first sewage flow outlet 2141 and a second sewage flow outlet 2142, the stopper 300 blocks the first sewage flow outlet 2141, the base frame 210 includes a first flat plate portion 211, a second flat plate portion 212 and a step portion 213 arranged between the first flat plate portion 211 and the second flat plate portion 212, the first sewage flow outlet 2141 is arranged on the first flat plate portion 211, and the second sewage flow outlet 2142 is arranged on the step portion 213.

[0100] In the above structure, the second sewage flow opening 2142 can not only be used to circulate sewage, but also bears the function of balancing the air pressure of the first cavity and the second cavity and the function of circulating clean water when the sewage tank is self-cleaning. The second sewage flow opening 2142 is arranged on the step portion 213 so that the clean water can be more easily circulated when the sewage tank is self-cleaning.

[0101] It should be noted that the second sewage flow opening 2142 includes a plurality of second sewage flow openings 2142 , and the plurality of second sewage flow openings 2142 are arranged at intervals on the step portion 213 .

[0102] On the other hand, the present application provides a cleaning device (not shown in the figure), which includes a cleaning component, a connecting rod and the above-mentioned sewage tank 10, wherein the cleaning component and the sewage tank are both connected to the connecting rod, and the cleaning component is in communication with the sewage tank 10. Since the sewage tank 10 has the advantage of preventing sewage from flowing back, the cleaning device having the same has the advantages of a long service life of the fan and a good user experience.
