The sewage tank generally includes a first cavity located below and a second cavity located above the first cavity. Sewage and solid waste are first entrained by the airflow and enter the second cavity.

[0009] In this way, the enclosure can surround at least part of the air inlet in the circumferential direction of the air inlet, thereby increasing the complexity of the airflow path, thereby reducing the moisture content of the airflow entering the airflow cavity. The extension portion is connected to the enclosure portion and extends to the side wall of the accommodating cavity, effectively blocking the sewage flowing along the inner wall of the box body, making it difficult for the sewage to pass over the extension portion and enter the airflow cavity.

[0010] In some embodiments, the sewage tank further includes a seal, which is disposed between the edge of the partition bracket and the cavity wall of the accommodating cavity to reduce the probability of water vapor flowing through the gap between the partition bracket and the inner wall of the tank body.

[0011] In some embodiments, the extension portion includes a mounting portion extending in a height direction of the box body, and the sealing member includes a first sealing member, which is disposed at an outer edge of the mounting portion and abuts against an inner wall of the accommodating cavity.

[0019] In some embodiments, the partition bracket also includes a bottom plate located below the shielding structure, the bottom plate divides the accommodating cavity into a first cavity and a second cavity, the bottom plate is provided with a sewage flow outlet, and the mounting portion extends from the bottom plate to the top plate.

And / or, the second end of the first seal extends to the upper surface of the third seal, and the third seal is used to seal the gap between the bottom plate and the inner wall of the box.

[0022] In some embodiments, the first seal, the second seal, and the third seal are an integrally formed structure.

[0023] On the one hand, this arrangement improves the integrity of the parts, so that the three scattered seals are integrated into an integral sealing structure, thereby improving assembly efficiency. On the other hand, the integrated arrangement of the first seal, the second seal, and the third seal can also prevent an installation gap from being generated between the two connected seals, thereby further improving the sealing effect of the seal.

[0024] In some embodiments, the extension portion further includes a second water retaining rib disposed on an outer wall of the enclosure portion, the second water retaining rib extending along a height direction of the enclosure portion, and an air flow opening is formed between the second water retaining rib and the mounting portion.

[0025] Such an arrangement can make it difficult for sewage to flow out from the gap between the first sealing member and the inner wall of the box body, thereby effectively blocking the sewage flowing along the inner wall of the box body.

[0026] In some embodiments, the extension portion further includes a reinforcement structure, which connects two opposite sides of the airflow opening. The reinforcement structure can further improve the connection stability of the mounting portion.

[0027] In some embodiments, the box body includes an outer cylinder, an inner cylinder arranged in the outer cylinder, and a box cover arranged on the top of the outer cylinder. The outer cylinder and the box cover together form a accommodating cavity. The first end of the inner cylinder extends to the bottom of the outer cylinder and is connected to the outside, and the second end of the inner cylinder passes through the bottom plate and extends to the second cavity; the port at the second end of the inner cylinder forms the air inlet of the box body, and the air outlet is arranged on the box cover.

[0030] With such arrangement, when the air flow enters the second cavity from the air inlet, the air flow flowing above the air inlet will be stopped by the top plate of the partition bracket, and the air flow flowing around the air inlet can be stopped by the first baffle or the inner wall of the box. After the air flow hits the above-mentioned point, the kinetic energy of the sewage and solid waste is reduced due to the obstruction, and they will fall under the action of gravity, thereby being separated from the gas.

[0031] In some embodiments, the enclosure portion further includes two second baffles spaced apart from each other, the first baffle is connected between the two second baffles, and the first baffle and the two second baffles together surround the outer side of the inner cylinder.

[0032] In some embodiments, the enclosure is connected by a top plate to a bottom plate.

[0033] Such an arrangement increases the length and complexity of the air flow channel, achieving a better air-water separation effect.

Since the sewage tank of the present application has the advantage of a long service life of the vacuum cleaner main unit, the cleaning device having the same also has the above-mentioned advantages.

[0035] The technical solution of this embodiment is applied, and the sewage tank includes a box assembly and a partition bracket arranged in the box assembly, and a shielding structure is arranged on the partition bracket, and the shielding structure can separate the second cavity into a sewage cavity and an airflow cavity, and the air inlet and the sewage flow port are both connected to the sewage cavity, and the sewage cavity serves as the main place for separating the airflow and sewage. The air outlet is connected to the airflow cavity, and the airflow first undergoes air-water separation in the sewage cavity and then enters the airflow cavity, and finally is discharged from the air outlet.

[0036] Specifically, the shielding structure can block part of the air inlet, and can extend from the partition bracket to the inner wall of the accommodating chamber. The shielding structure can stop the airflow entering from the air inlet. After the airflow carrying sewage and solid waste hits the shielding structure, the sewage and solid waste can stop moving and fall under the action of gravity, thereby achieving separation from the airflow. Sewage and solid waste can flow into the first cavity and gather, while the airflow continues to flow to the airflow cavity and is finally discharged from the air outlet, so that the airflow carrying sewage can achieve more complete water vapor separation in the sewage cavity. In addition, since the shielding structure extends to the inner wall of the accommodating chamber, the airflow opening connecting the sewage cavity and the airflow cavity is arranged on the shielding structure, thereby reducing the probability of water vapor flowing through the gap between the partition bracket and the box body, so as to prevent the water flow attached to the inner wall of the box body from entering the airflow cavity, thereby further reducing the moisture content of the airflow entering the airflow cavity, and further reducing the probability of water vapor entering the vacuum cleaner main unit.

[0049] 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.

[0050] In the related art, when a floor scrubber is cleaning the floor, the airflow generated by the vacuum main unit will suck sewage and solid particles into a sewage tank, and the airflow is separated from the sewage and solid waste through the sewage tank.

[0051] Specifically, a partition bracket is generally provided in the sewage tank, and the partition bracket divides the sewage tank into a second cavity and a first cavity. The first cavity is located at the bottom of the sewage tank and is used to collect sewage. The second cavity is located above the first cavity and is used to separate the airflow from sewage and solid waste. The second cavity is connected to the first cavity through a sewage flow port, and a non-return structure is generally provided at the sewage flow port to prevent the sewage in the sewage cavity from flowing back into the second cavity. 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 sewage flow port, and the solid waste remains in the second cavity. The airflow is discharged from the air outlet at the top of the second cavity to achieve the separation of liquid, solid and gas.

[0052] However, the airflow entering the vacuum cleaner main unit still carries a large amount of moisture. After research, the inventor found that there is a gap between the partition bracket and the inner wall of the sewage tank. This gap increases the flow area between the first cavity and the second cavity. When the sewage tank works by relying on negative pressure airflow, moisture will enter the second cavity from the gap, thereby increasing the moisture content of the airflow entering the vacuum cleaner main unit.

[0053] Based on the above problems, the present application provides a sewage tank for a cleaning device, which divides the accommodating cavity into a first cavity and a second cavity by arranging a partition bracket in the sewage tank, and effectively divides the second cavity by a shielding structure on the partition bracket, so that the second cavity is divided into a sewage cavity and an airflow cavity, so that the airflow carrying sewage and impurities is more thoroughly separated from water vapor in the sewage cavity, and then enters the airflow cavity and is discharged from an outlet connected to the airflow cavity, thereby reducing the water vapor content of the airflow entering the vacuum cleaner main unit.

[0054] 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.

[0055] Figure 1 A cross-sectional view of a sewage tank provided in an embodiment of the present application; Figure 2 Figure 1 An enlarged structural diagram of the sewage tank at A; Figure 3 A three-dimensional diagram of the internal structure of a sewage tank provided in an embodiment of the present application; Figure 4 Figure 3 An enlarged structural diagram of the sewage tank at B; Figure 5 A three-dimensional structural diagram of the partition bracket provided in an embodiment of the present application.

[0056] In a first aspect, the present application provides a sewage tank for a cleaning device, wherein the sewage tank comprises: a tank body 100 and a partition bracket 200 .

[0057] The box body 100 has a receiving cavity, and the receiving cavity has an air inlet 103 and an air outlet 104;

[0058] 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 partition bracket 200 has a shielding structure 220, and the shielding structure 220 surrounds at least part of the air inlet 103, and the shielding structure 220 extends to the inner wall of the accommodating cavity to separate the second cavity 102 into a sewage cavity 1021 and an airflow cavity 1022. The sewage cavity 1021 is connected to the air inlet 103, and the airflow cavity 1022 is connected to the air outlet 104; the shielding structure 220 has an airflow opening 105 connecting the sewage cavity 1021 and the airflow cavity 1022.

[0059] Using the technical solution of this embodiment, the sewage tank 10 includes a box body 100 and a partition bracket 200 disposed in the box body 100, and a shielding structure 220 is disposed on the partition bracket 200. The shielding structure 220 can separate the second cavity 102 into a sewage cavity 1021 and an airflow cavity 1022. The air inlet 103 and the sewage flow port 2111 are both connected to the sewage cavity 1021, and the sewage cavity 1021 serves as the main place for separating airflow and sewage. The air outlet 104 is connected to the airflow cavity 1022, and the airflow first undergoes air-water separation in the sewage cavity 1021 and then enters the airflow cavity 1022, and finally is discharged from the air outlet 104.

[0060] Specifically, the shielding structure 220 can shield part of the air inlet 103, and can extend from the partition bracket 200 to the inner wall of the accommodating cavity. The shielding structure 220 can stop the airflow entering from the air inlet 103. After the airflow carrying sewage and solid waste hits the shielding structure 220, the sewage and solid waste can stop moving and fall under the action of gravity, thereby achieving separation from the airflow. The sewage and solid waste can flow into the first cavity 101 and gather, while the airflow continues to flow to the airflow cavity 1022 and is finally discharged from the air outlet 104, so that the airflow carrying sewage can achieve more complete water vapor separation in the sewage cavity 1021. In addition, since the shielding structure 220 extends to the inner wall of the accommodating cavity, the airflow opening 105 connecting the sewage cavity 1021 and the airflow cavity 1022 is arranged on the shielding structure 220, thereby reducing the probability of water vapor flowing through the gap between the partition bracket 200 and the box body 100, so as to prevent the water flow attached to the inner wall of the box body from entering the airflow cavity, thereby further reducing the moisture content of the airflow entering the airflow cavity, and further reducing the probability of water vapor entering the vacuum cleaner host.

[0061] After research, the inventor found that the moisture entering the vacuum cleaner main unit comes from the following sources: 1. Since the moisture carried in the airflow is difficult to be completely separated in the second cavity, there is too much water vapor entrained in the airflow, which in turn causes the airflow entering the vacuum cleaner main unit to have a high moisture content. 2. Since the vacuum cleaner main unit provides power by forming a negative pressure, the airflow is discharged from the air outlet in a sucked manner, causing the sewage in the second cavity to easily flow into the air outlet along the inner wall of the second cavity, and then be further entrained by the airflow into the interior of the vacuum cleaner main unit.

[0062] In view of this, in the present embodiment, the shielding structure 220 includes an enclosure portion 221 and an extension portion 222, the enclosure portion 221 surrounds at least a portion of the air inlet 103 in the circumferential direction of the air inlet 103, the extension portion 222 is connected to the enclosure portion 221 and extends to the side wall of the accommodating cavity, and the airflow opening 105 is located in the extension portion 222.

[0063] In the above structure, the enclosure 221 can surround at least part of the air inlet 103 in the circumferential direction of the air inlet 103, thereby increasing the complexity of the airflow flow path. The enclosure 221 can stop the airflow entering from the air inlet 103. After the airflow carrying sewage and solid waste hits the enclosure 221, the sewage and solid waste can stop moving and fall under the action of gravity, thereby achieving separation from the airflow. The airflow needs to bypass the enclosure 221 and enter the airflow cavity from the airflow opening 105 on the extension portion 222. In this process, it continues to experience collisions with the enclosure 221 and the inner wall of the box body 100, thereby further reducing the water content in the airflow.

[0064] The extension portion 222 is connected to the enclosure portion 221 and extends to the side wall of the accommodating chamber, thereby effectively blocking the sewage flowing along the inner wall of the box body 100, making it difficult for the sewage to pass through the extension portion 222 and enter the airflow chamber, so that the gas entering the airflow chamber has a lower water content, thereby further reducing the probability of sewage flowing into the vacuum cleaner main unit, thereby ensuring the service life of the vacuum cleaner main unit.

[0065] like Figures 3 to 5 As shown, in some embodiments, the sewage tank further includes a sealing member 300, and the sealing member 300 is disposed between the edge of the partition bracket 200 and the cavity wall of the accommodating cavity.

[0066] The seal 300 can be used to seal the gap between the partition bracket 200 and the housing 100, thereby preventing water vapor from entering the airflow cavity through the gap between the partition bracket 200 and the housing 100, thereby effectively reducing the probability of water vapor entering the vacuum cleaner main unit.

[0067] Specifically, if Figures 3 to 5 As shown, in some embodiments, the extension portion 222 includes a mounting portion 2221 extending along the height direction of the box body 100, and the seal 300 includes a first seal 310, which is arranged on the outer edge of the mounting portion 2221 and abuts against the inner wall of the accommodating cavity.

[0068] In the above structure, the extension portion 222 includes a mounting portion 2221 extending along the height direction of the box body 100. The mounting portion 2221 can abut the first sealing member 310 against the inner wall of the accommodating cavity. The mounting portion 2221 can ensure the tightness of the abutment between the first sealing member 310 and the inner wall of the box body 100, so that it is difficult for sewage to flow out from the gap between the first sealing member 310 and the inner wall of the box body 100, thereby effectively blocking the sewage flowing along the inner wall of the box body 100.

[0069] It should be noted that the flow blocking effect of the mounting portion 2221 and the first sealing member 310 can be ensured by setting the distance that the mounting portion protrudes relative to the inner wall of the box body 100. For example, the distance between the inner surface of the mounting portion 2221 and the inner wall of the box body 100 can be greater than 3 mm, so that the water flow attached to the inner wall of the box body 100 is difficult to pass over the mounting portion 2221 and enter the airflow cavity.

[0070] like Figures 3 to 5 As shown, in some embodiments, a mounting groove 2221 a is disposed on the outer edge of the mounting portion 2221 , and the first sealing member 310 is disposed in the mounting groove 2221 a .

[0071] In the above structure, the mounting groove 2221a can improve the stability of the fixing of the first sealing member 310 and prevent the first sealing member 310 from moving, thereby ensuring the blocking effect on the sewage.

[0072] Specifically, refer to Figure 4 As shown, the installation groove 2221a includes two oppositely arranged groove side walls and a groove bottom wall arranged between the two groove side walls. The groove bottom wall and the inner wall of the box body 100 can produce an extrusion effect on the first seal 310 to ensure the tightness of the first seal 310 abutting against the inner wall of the box body 100. The two groove side walls can limit the first seal 310 to prevent the first seal 310 from moving with the flow of airflow, thereby ensuring the stability of the installation of the first seal 310.

[0073] It should be noted that the first sealing member 310 may be a sealing strip, which includes a sealing body inserted into the mounting groove and a sealing portion disposed on the sealing body, and the sealing portion abuts against the inner wall of the box body 100 to achieve a better sealing effect.

[0074] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the partition bracket 200 further includes a top plate 230 located above the shielding structure 220, and a gas flow port is provided on the top plate 230, and the gas flow port communicates with the air flow cavity 1022 and the air outlet 104. The top plate 230 can be sandwiched between the box body 100 and the box cover 113 to install the partition bracket 200 in the box body 100.

[0075] like Figure 3 and Figure 5 As shown, in some embodiments, the top of the enclosure portion 221 is connected to the bottom of the top plate 230, the extension portion 222 also includes a first water retaining rib 2222, the upper edge of the first water retaining rib 2222 is connected to the top plate 230, the first end of the first water retaining rib 2222 is connected to the enclosure portion 221, and the second end of the first water retaining rib 2222 is connected to the mounting portion 2221.

[0076] In the above structure, the top of the enclosure 221 is connected to the bottom of the top plate 230. When the airflow enters the second cavity 102 from the air inlet 103, the airflow flowing above the air inlet 103 will be stopped by the top plate 230 of the partition bracket 200, and the airflow flowing around the air inlet 103 can be stopped by the enclosure 221 or the inner wall of the box 100. After the airflow hits the above point, the kinetic energy of the sewage and solid waste is reduced after being blocked, and they will fall under the action of gravity, thereby achieving separation from the gas.

[0077] The top end of the enclosure 221 is connected to the bottom of the top plate 230 , and the enclosure 221 can stop the water flow attached to the top plate 230 to reduce the probability of the water flow flowing into the exhaust port 2321 along the lower surface of the top plate 230 .

[0078] like Figure 5 As shown, the first water retaining rib 2222 can further play a role in separating the sewage chamber 1021 and the airflow chamber 1022 , further reducing the probability of sewage entering the airflow chamber 1022 along the lower surface of the top plate 230 .

[0079] like Figures 1 to 5 As shown, in some embodiments, the partition bracket 200 further includes a bottom plate 210 located below the shielding structure 220, and the bottom plate 210 divides the accommodating cavity into a first cavity 101 and a second cavity 102. The bottom plate 210 is provided with a sewage flow port 2111, and the mounting portion 2221 extends from the bottom plate 210 to the top plate 230.

[0080] In the above structure, the partition bracket 200 can divide the accommodating cavity into three cavities, that is, the bottom plate 210 divides the airflow cavity into a first cavity and a second cavity distributed up and down, and the first cavity and the second cavity are connected through the sewage flow port. The shielding structure 220 of the partition bracket 200 can divide the second cavity into a sewage cavity 1021 and an airflow cavity 1022. The airflow entering from the air inlet 103 first enters the sewage cavity 1021, and after the air and water are separated in the sewage cavity 1021, it is discharged from the airflow cavity 1022. The sewage and impurities remain in the sewage cavity 1021 and finally enter the first cavity through the sewage flow port 2111 for storage.

[0081] The mounting portion 2221 extends from the bottom plate 210 to the top plate 230 so that the mounting portion 2221 can provide mounting support for the first sealing member in the height direction of the box, thereby ensuring the mounting fastness and sealing effect of the first sealing member.

[0082] like Figure 5 As shown, in some embodiments, the seal 300 further includes a second seal 320 disposed on the circumferential outer side of the top plate 230 and a third seal 330 disposed on the circumferential outer side of the bottom plate 210 .

[0083] Specifically, the second sealing member 320 is used to seal the gap between the top plate 230 and the inner wall of the box body 100 , and the third sealing member 330 is used to seal the gap between the bottom plate 210 and the inner wall of the box body 100 .

[0084] It should be noted that the top plate 230 of the partition bracket 200 has a clamping portion clamped between the box body 100 and the box cover 113 and a main body portion located in the box body 100, and the second sealing member 320 is arranged on the circumferential outer side of the main body portion of the top plate 230. When the partition bracket 200 is installed in the box body 100, the clamping portion of the top plate is located between the box body 100 and the box cover 113. Since the main body portion of the top plate is provided with the second sealing member 320, a seal can be formed between the top plate 230 and the inner wall of the box body 100. Further, since the first end of the first sealing member 310 extends to the lower surface of the second sealing member 320, it is difficult for sewage to flow into the exhaust port 2321 along the lower surface of the top plate 230.

[0085] Correspondingly, a third seal 330 is provided on the circumferential outer side of the bottom plate 210, and the third seal 330 is used to seal the gap between the bottom plate 210 and the inner wall of the box body 100. The second end of the first seal 310 can extend to the upper surface of the third seal 330, thereby making it difficult for sewage to flow into the airflow cavity along the upper surface of the bottom plate 210, which helps to reduce the moisture content of the airflow entering the airflow cavity, thereby reducing the probability of sewage entering the vacuum cleaner main unit.

[0086] like Figure 5 As shown, in some embodiments, the first seal 310, the second seal 320, and the third seal 330 are an integrally formed structure.

[0087] On the one hand, this arrangement improves the integrity of the parts, so that the three scattered seals are integrated into an integral sealing structure, thereby improving assembly efficiency. On the other hand, the integrated arrangement of the first seal 310, the second seal 320, and the third seal 330 can also prevent an installation gap from being generated between the two connected seals, thereby further improving the sealing effect of the seal.

[0088] It should be noted that when processing the integrally formed first seal 310, second seal 320 and third seal 330, the partition bracket 200 can be placed in a mold, and then the first seal 310, second seal 320, and third seal 330 can be integrally processed by injection molding.

[0089] Figure 6 A schematic diagram of the three-dimensional structure of the shielding structure provided in the embodiment of the present application is shown in FIG. Figure 6As shown, in some embodiments, the extension portion 222 further includes a second water retaining rib 2223 disposed on the outer wall of the enclosure portion 221 , the second water retaining rib 2223 extends along the height direction of the enclosure portion 221 , and an air flow opening 105 is formed between the second water retaining rib 2223 and the mounting portion 2221 .

[0090] In the above structure, the second water retaining rib 2223 can block the water flow attached to the outer surface of the enclosure 221, so that the water flow attached to the outer surface of the enclosure 221 cannot flow into the airflow cavity along the outer surface of the enclosure 221, thereby further reducing the water content of the gas entering the airflow cavity, and further reducing the probability of water vapor entering the vacuum cleaner main unit.

[0091] It should be noted that the first water retaining rib 2222 and the reinforcing structure 2224 may be disposed between the second water retaining rib 2223 and the mounting portion 2221 , so that the fixing stability of the mounting portion 2221 is better.

[0092] like Figures 3 to 5 As shown, in some embodiments, the extension portion 222 further includes a reinforcement structure 2224 , and the reinforcement structure 2224 connects two opposite sides of the air flow opening 105 .

[0093] In the above structure, the reinforcing structure 2224 can further enhance the connection stability of the mounting portion 2221 .

[0094] Specifically, the reinforcing structure 2224 may be a reinforcing rib of the enclosure portion 221 and the extension portion 222. The reinforcing rib may be one or more. Exemplarily, a plurality of reinforcing ribs are provided, and the plurality of reinforcing ribs are spaced apart in the height direction of the box body 100.

[0095] It should be noted that the setting of the reinforcement structure 2224 will occupy the space of the airflow opening 105 and affect the flow area of ​​the airflow, so the setting of the reinforcement structure 2224 should not occupy too much space of the airflow channel. For example, the flow area of ​​the airflow channel can be guaranteed to be not less than 600mm to ensure the smoothness of the airflow.

[0096] like Figures 1 to 3 As shown, in some embodiments, the box body 100 includes an outer cylinder 111, an inner cylinder 112 arranged in the outer cylinder 111, and a box cover 113 covered on the top of the outer cylinder 111, the outer cylinder 111 and the box cover 113 together form a accommodating cavity, the first end of the inner cylinder 112 extends to the bottom of the outer cylinder 111 and is connected to the outside, the second end of the inner cylinder 112 passes through the bottom plate 210 and extends to the second cavity 102; the port at the second end of the inner cylinder 112 forms the air inlet 103 of the box body 100, and the air outlet 104 is arranged on the box cover 113.

[0097] In the above structure, the inner cylinder 112 is used to circulate airflow, and the airflow can carry solid waste and sewage into the outer cylinder 111, and separate and process them in the outer cylinder 111. Specifically, the airflow can carry solid waste and sewage into the second cavity 102, and after air-water separation, the airflow can be discharged from the air outlet 104, and the solid waste and sewage are temporarily stored in the second cavity 102, and then enter the first cavity 101 through the sewage flow port for collection.

[0098] like Figures 2 to 5 As shown, in some embodiments, the enclosure 221 includes a first baffle 2211, the first baffle 2211 is connected to at least one of the bottom plate 210 and the top plate 230, and the first baffle 2211 is arranged on the side of the inner cylinder 112 away from the sewage flow port 2111. In the above structure, after the airflow enters the second cavity 102 from the air inlet 103, the airflow flowing above the air inlet 103 will be stopped by the top plate 230 of the partition bracket 200, and the airflow flowing around the air inlet 103 can be stopped by the first baffle 2211 or the inner wall of the box 100. After the airflow hits the above, the kinetic energy of the sewage and solid waste is reduced after being blocked, and they will fall under the action of gravity, thereby achieving separation from the gas.

[0099] It should be noted that the first baffle 2211 may be connected only to the bottom plate 210, or the first baffle 2211 may be connected only to the top plate 230, or the first baffle 2211 is connected to both the bottom plate 210 and the top plate 230. For example, the upper edge of the first baffle 2211 is connected to the top plate 230, and the lower edge of the first baffle 2211 is connected to the bottom plate 210, together to achieve a better separation effect.

[0100] In order to further increase the length and complexity of the air flow channel and achieve better air-water separation effect, such as Figures 3 to 5 As shown, in some embodiments, the enclosure 221 further includes two second baffles 2212 spaced apart, the first baffle 2211 is connected between the two second baffles 2212 , and the first baffle 2211 and the two second baffles 2212 together surround the outer side of the inner cylinder 112 .

[0101] In the above structure, the first baffle 2211 and the second baffle 2212 can form a "semi-enclosed" structure on the circumferential outer side of the inner cylinder 112, so that the airflow flowing out of the inner cylinder 112 can fully contact the shielding structure 220 and the inner wall of the outer cylinder 111, thereby improving the effect of air-water separation. The airflow can flow into the airflow cavity from the gap between the second baffle 2212 and the inner wall of the outer cylinder 111, effectively reducing the water content of the airflow entering the airflow cavity.

[0102] Exemplarily, the angle between the second baffle 2212 and the first baffle 2211 may be between 45° and 135°. The present embodiment does not limit the specific angle between the second baffle 2212 and the first baffle 2211 .

[0103] In some embodiments, the enclosure 221 is connected to the bottom plate 210 by the top plate 230. Exemplarily, the lower edges of the first baffle 2211 and the second baffle 2212 are connected to the bottom plate 210, and the upper edges of the first baffle 2211 and the second baffle 2212 are connected to the top plate 230. That is, the airflow cannot enter the airflow cavity from the gap between the enclosure 221 and the bottom plate or the top plate, and can only enter the airflow cavity from the outer edge of the second baffle 2212 and the inner wall of the outer cylinder 111, thereby effectively extending the flow path of the airflow, increasing the complexity of the airflow channel, and helping to improve the effect of air-water separation.

[0104] It should be noted that, in some embodiments, the top of the enclosure portion 221 is connected to the top plate 230 and separates the top plate 230 into a first top plate portion 231 and a second top plate portion 232 . The first top plate portion 231 separates the air inlet 103 and the air outlet 104 , and the exhaust port 2321 is arranged on the second top plate portion 232 .

[0105] In the above structure, the top of the enclosure 221 is connected to the top plate 230 to enhance the shielding effect of the enclosure 221 on the airflow, making it difficult for the airflow to enter the airflow cavity along the lower surface of the top plate 230. At the same time, the top plate 230 can also play the role of separating the air inlet 103 and the air outlet 104. The airflow entering from the air inlet 103 will not be discharged directly from the air outlet 104, but will pass through the airflow opening 105 between the shielding structure 220 and the extension part, and then enter the airflow cavity, and finally be discharged from the air outlet 104, which effectively reduces the water content of the airflow entering the air outlet 104.

[0106] Reference Figures 1 to 5 As shown, the bottom of the enclosure 221 is connected to the bottom plate 210, and the bottom plate 210 is divided into a first bottom plate portion 211 and a second bottom plate portion 212. The sewage flow-through port 2111 is provided on the first bottom plate portion 211, and the second bottom plate portion 212 is provided with an air pressure balance port 2121 that connects the first cavity 101 and the second cavity 102. Specifically, the bottom plate 210 can separate the box body 100 into the first cavity 101 and the second cavity 102. The first cavity 101 plays the role of collecting sewage and solid waste. The third sealing member 330 is provided on the circumferential outer side of the bottom plate 210, so that the first cavity 101 and the second cavity 102 are connected only through the sewage flow-through port 2111 and the air pressure balance port 2121.

[0107] Specifically, an anti-backflow structure may be provided at the sewage flow outlet 2111 to prevent the sewage in the first cavity 101 from flowing back from the sewage flow outlet 2111 into the second cavity.

[0108] Since the second cavity is directly connected to the air outlet 104, it is easy to cause the air pressure in the second cavity to be lower than the air pressure in the first cavity, making it difficult for sewage to flow smoothly into the first cavity. The air pressure balance port 2121 can balance the air pressure between the second cavity and the first cavity, so that sewage can flow smoothly from the second cavity into the first cavity.

[0109] It should also be noted that the sewage tank also includes a filter assembly, which is disposed in the air outlet 104 of the tank cover 113 and is used to filter the airflow to reduce the probability of impurities being carried in the airflow to ensure the cleanliness of the gas blown out from the cleaning device. Exemplarily, the filter assembly can be a HEPA filter.

[0110] In some embodiments, the sewage tank further includes a water level detection device, which can detect the water level of the sewage in the first cavity 101. When the water level exceeds a predetermined position, a signal can be sent to the controller of the cleaning device to stop the rotation of the vacuum main unit or send a signal to the user to clean the sewage tank. This arrangement can further reduce the risk of damage to the vacuum main unit.

[0111] On the other hand, the present application also provides a cleaning device, including: a cleaning component, a connecting rod and a sewage tank 10, wherein the sewage tank 10 is the above-mentioned sewage tank, the cleaning component and the sewage tank 10 are both connected to the connecting rod, and the cleaning component and the air inlet 103 of the sewage tank are connected. Since the sewage tank 10 has the advantage of preventing sewage backflow, the cleaning device having the same has the advantages of a long service life of the vacuum cleaner main unit and a good user experience.
