When the cleaning equipment is used in a flat state, the sewage in the sewage tank will be stirred, and the sewage will have a high probability of being stirred into the air outlet channel and finally entering the fan module, thereby damaging the fan module and other components. SUMMARY

[0010] By adopting the above technical solution, the space in the tank body is divided into the temporary storage cavity, the barrier cavity and the liquid storage cavity by two partitions, and at the same time, the main body of the support forms two negative pressure channels to meet the corresponding space area division.

[0011] In some embodiments, in the second direction, the bottom end of the temporary storage cavity is communicated with the bottom end of the barrier cavity, and the top end of the barrier cavity is communicated with the top end of the liquid storage cavity.

[0012] By adopting the above technical solution, the bottom end of the temporary storage cavity is communicated with the bottom end of the barrier cavity to realize that the sewage is quickly sucked into the barrier cavity, and the top end of the barrier cavity is communicated with the top end of the liquid storage cavity to meet that the sewage flows into the liquid storage cavity in the conventional working posture.

[0013] In some embodiments, the first partition is provided with a first water passing structure for connecting the temporary storage cavity and the barrier cavity; the second partition is provided with a second water passing structure for connecting the liquid storage cavity and the barrier cavity; the first water passing structure and the second water passing structure form a height difference, and the height position of the first water passing structure is lower than that of the second water passing structure.

[0014] By using the above technical scheme, the water passing structures meet the corresponding space connection requirements, and the two water passing structures form a height difference, that is, the spaces inside the box are connected in a staggered manner, so as to reduce the probability of sewage entering the temporary storage cavity due to agitation.

[0015] In some embodiments, one end of the first partition is inclined away from the air outlet with the first water passing structure; and / or,

The two parts of the gas are combined at the air outlet end or before reaching the air outlet end. The baffle is used to block the second air outlet, so as to reduce or avoid the sewage from entering the second negative pressure channel due to surging and then flowing along the second negative pressure channel to the negative pressure source.

[0055] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which like reference numerals refer to like elements or elements having similar functions. The embodiments described below are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0056] In the description of the present application, it should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0057] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0058] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0059] The washing and mopping integrated cleaning device can simultaneously meet the requirements of collecting sewage and sundries, so the main body of the washing and mopping integrated cleaning device is provided with a sewage tank, and the sewage and sundries collected by the brush module under the negative pressure action of the fan module are transported through the sewage inlet pipeline and collected in the sewage tank for temporary storage.

[0060] Due to the characteristics that the washing and mopping integrated cleaning device can be used in dry and wet scenes, the structure of the sewage tank needs certain waterproof sealing to reduce the invasion of water vapor into the fan module and cause damage to the fan motor. During normal cleaning, the main body of the cleaning device is usually in an upright or approximately upright posture, so only a certain sealing is needed at the position of the air outlet at the top of the sewage tank, which can greatly reduce the probability of water vapor entering the fan.

[0061] However, in some special use scenarios, the main body of the cleaning device needs to be placed flat to clean some sanitary dead angles, such as cleaning the bottom of the bed, the bottom of the wardrobe, etc., or the main body of the cleaning device is passively placed flat in the water storage state, and when the main body of the cleaning device is used in a flat state, the sewage in the sewage tank will appear a phenomenon of splashing, so the sewage has a great probability of splashing into the fan module, causing damage to the fan module.

[0062] Therefore, the sewage tank provided by the application can greatly reduce the probability of sewage entering the negative pressure source after being stirred.

[0063] Please refer to Figures 1 to 6 In a first aspect, the embodiments of the application provide a sewage tank 100 comprising a tank body 10. The tank body 10 has an air inlet end 10a and an air outlet end 10b arranged oppositely, and the air outlet end 10b is used to be connected to a negative pressure source. In a first direction X, the tank body 10 has a temporary storage cavity 101, a barrier cavity 102 and a liquid storage cavity 103 connected in sequence. In a second direction Y, the tank body 10 further has a first negative pressure channel 104 and a second negative pressure channel 105 arranged in a stack from bottom to top. The temporary storage cavity 101 is connected to the air outlet end 10b through the first negative pressure channel 104. The barrier cavity 102 is connected to the air outlet end 10b through the second negative pressure channel 105.

[0064] In the tank body 10, a part of the gas entering from the air inlet end 10a passes through the temporary storage cavity 101, the first negative pressure channel 104 and the air outlet end 10b in sequence, and another part of the gas passes through the temporary storage cavity 101, the barrier cavity 102, the second negative pressure channel 105 and the air outlet end 10b in sequence. The two parts of the gas are combined at the air outlet end 10b or before reaching the air outlet end 10b. The sewage entering the tank body 10 with the gas is separated from the gas in the temporary storage cavity 101, and is stored in the liquid storage cavity 103 after passing through the barrier cavity 102.

[0065] It can be understood that the box 10 is the main part of the sewage tank 100, and the box 10 should have a space for accommodating sewage. The air inlet end 10a and the air outlet end 10b are two ends of the box 10 arranged opposite to each other in the length direction of the box 10. The air inlet end 10a is the end through which sewage, gas and solid impurities enter the inside of the box 10. The air inlet end 10a should be provided with an air inlet, and a sewage inlet pipeline is usually arranged at the air inlet. One end of the sewage inlet pipeline is communicated with the air inlet, and the other end extends towards the air outlet end, that is, the sewage, gas and solid impurities enter from the air inlet end 10a and are transported to the temporary storage cavity 101 through the sewage inlet pipeline. The air outlet end 10b should also be provided with an air outlet communicated with a negative pressure source such as a fan module and a motor. When the negative pressure source works, the gas enters from the air inlet end 10a and flows out from the air outlet end 10b. In addition, the first direction X is the direction from the air outlet end 10b to the air inlet end 10a, and the second direction Y is the upside-down direction of the box.

[0066] The temporary storage cavity 101 is a chamber in the internal space of the box 10, and the temporary storage cavity 101 is close to the air outlet end 10b. The temporary storage cavity 101 can be used to realize solid-liquid separation of the sewage entering the chamber, that is, the solid such as particulate matter and impurities is stored in the temporary storage cavity 101, the sewage flows into the blocking cavity 102 and is finally stored in the liquid storage cavity 103, and the temporary storage cavity 101 can also be used for temporary storage of the sewage. The blocking cavity 102 is a chamber between the temporary storage cavity 101 and the liquid storage cavity 103. The blocking cavity 102 is used to separate the temporary storage cavity 101 and the liquid storage cavity 103, to reduce or avoid the sewage in the liquid storage cavity 103 from entering the temporary storage cavity 101 or the second negative pressure channel 105 due to agitation, thereby affecting the negative pressure source. At the same time, the blocking cavity 102 can also have the function of gas-liquid separation. The liquid storage cavity 103 is a chamber for storing sewage, and is close to the air inlet end 10a.

[0067] The first negative pressure channel 104 and the second negative pressure channel 105 are used for the gas to enter the box 10 from the outside and then enter the negative pressure source from the inside of the box 10. Here, the negative pressure channel can be formed by the inner wall of the box 10 or can be realized by arranging a pipeline. For example, a support 20 is arranged in the box 10, the first negative pressure channel 104 is formed by using the internal space of the support 20, and the second negative pressure channel 105 is formed by surrounding the support 20 with the inner wall of the box 10.

[0068] The first negative pressure channel 104 and the second negative pressure channel 105 are two independent gas passing channels, that is, the gas entering the box 10, one part of which passes through the temporary storage cavity 101 and the first negative pressure channel 104 to the gas outlet end 10b, and the other part of which passes through the temporary storage cavity 101, the blocking cavity 102 and the second negative pressure channel 105 to the gas outlet end 10b. In this way, the second negative pressure channel 105 can further increase the negative pressure in the blocking cavity 102, so that the sewage can enter the blocking cavity 102 more quickly. As shown in the figure, the path of the gas flowing in the first negative pressure channel 104 is indicated by the arrow a, and the path of the gas flowing in the second negative pressure channel 105 is indicated by the arrow b.

[0069] It should be understood that the sewage tank 100 should be in a normal working posture and a prone posture, wherein when the sewage tank 100 is in the working posture, the length direction of the sewage tank 100 is at an angle to the ground to be cleaned, as shown in the figure a. Figure 1 As shown in the figure, the gas enters the box 10 along with the sewage from the gas inlet end 10a, and first enters the temporary storage cavity 101, and the solid such as particulate matter and impurities is left in the temporary storage cavity 101, and the sewage flows into the blocking cavity 102 and is finally stored in the liquid storage cavity 103; part of the gas enters the gas outlet end 10b through the temporary storage cavity 101 and the first negative pressure channel 104 to suck the dirt on the ground to be cleaned into the temporary storage cavity 101, and the other part of the gas enters the gas outlet end 10b through the temporary storage cavity 101, the blocking cavity 102 and the second negative pressure channel 105 to maintain the negative pressure of the temporary storage cavity 101, further improving the flow rate of the sewage into the blocking cavity 102 and the liquid storage cavity 103. When the sewage tank 100 is in the prone posture, the blocking cavity 102 is in communication with the temporary storage cavity 101, and under the action of the second negative pressure channel 105, the negative pressure in the negative pressure environment formed by the blocking cavity 102 and the liquid storage cavity 103 is greater than the negative pressure in the temporary storage cavity 101. Therefore, the sewage entering the temporary storage cavity 101 can be pressed into the blocking cavity 102 under the action of the pressure, and under the action of the first negative pressure channel 104, the sewage tank can also suck the sewage in the prone posture state. In this way, the horizontal suction force of the sewage surface of the temporary storage cavity 101 can be effectively formed to improve the splashing phenomenon of the sewage caused by the splashing, and the probability of the sewage entering the negative pressure source from the gas outlet end 10b when the sewage tank 100 is in the prone state can be effectively reduced.

[0070] The sewage tank 100 provided by the application, in the normal working posture, gas enters the tank body 10 from the gas inlet end 10a, and part of the gas enters the gas outlet end 10b from the temporary storage cavity 101, the blocking cavity 102 and the second negative pressure channel 105 in turn, so that a negative pressure is formed in the blocking cavity 102, the sewage in the temporary storage cavity 101 is stored in the blocking cavity 102, and then is stored in the liquid storage cavity 103 through the blocking cavity 102, thereby increasing the gas-liquid separation effect. In the prone posture, the sewage, which originally has a small amount of liquid, is still stored in the liquid storage cavity 103, and the blocking cavity 102 between the temporary storage cavity 101 and the liquid storage cavity 103 can minimize or avoid water splashing into the negative pressure source; until the storage amount of the sewage triggers the liquid level detection device to prompt the user to pour the sewage, and in the prone posture, the newly entered sewage in the tank body 10 is also sucked into the blocking cavity 102, and the sewage can also enter the liquid storage cavity 103 from the blocking cavity 102 when the sewage tank is turned to the normal working posture, and the second negative pressure channel 105 can also form a negative pressure in the blocking cavity 102 to form a suction force on the sewage, so that the sewage quickly enters the blocking cavity 102 from the temporary storage cavity 101, further reducing the water splashing phenomenon, and in the prone posture, the blocking cavity 102 can also be directly used for storing sewage, that is, after the second negative pressure channel 105 forms a negative pressure environment in the blocking cavity 102, the sewage in the temporary storage cavity 101 can also be sucked into the blocking cavity 102 and temporarily stored in the blocking cavity 102 in the prone posture, here, the prone posture refers to a smaller angle between the tank body and the ground to be cleaned, and in the normal working posture, the sewage flows from the blocking cavity 102 into the liquid storage cavity 103, here, the normal working posture refers to a larger angle between the tank body and the ground to be cleaned, and the posture of the tank body can also be judged by whether the sewage can be temporarily stored in the blocking cavity 102, for example, when the sewage can be stored in the blocking cavity 102, the tank body 10 is in the prone posture, and when the sewage cannot be stored in the blocking cavity 102, the tank body 10 is in the normal working posture. The sewage tank 100 provided by the application can greatly reduce the probability of sewage splashing into the negative pressure source, especially when the sewage tank 100 changes from the normal working posture to the prone posture, the added blocking cavity 102 can avoid the sewage in the liquid storage cavity 103 from immediately entering the temporary storage cavity 101, and can also reduce the size of water splashing caused by sewage splashing, and the continuous negative pressure formed in the two sets of negative pressure channels in the temporary storage cavity 101 can minimize the impact of sewage splashing.

[0071] Please refer to Figure 1 、 Figures 4 to 9In some embodiments, the sewage tank 100 further comprises a support 20 and a second partition 30 arranged in the tank body 10. The support 20 comprises a main body 21 and a first partition 22 connected to the main body 21. The first partition 22 and the second partition 30 are arranged in the first direction X to divide the internal space of the tank body 10 into a temporary storage cavity 101, a barrier cavity 102, and a liquid storage cavity 103. In the second direction Y, the main body 21 has a first negative pressure channel 104 and a second negative pressure channel 105 arranged in layers from bottom to top.

[0072] It can be understood that each partition is used to divide the internal space of the tank body 10. The partition can be a plate structure such as a baffle or a barrier, or a part of another structure that plays a partitioning role. As shown in Figure 1 , Figure 8 and Figure 9 , the first partition 22 is a bottom plate structure of the support 20. The main body 21 is connected to the bottom plate structure. The side walls of the bottom plate structure abut the inner wall of the tank body 10. At this time, the bottom plate structure, the side walls of the main body 21, and the inner wall of the tank body 10 form the temporary storage cavity 101. Of course, in order for external sewage and airflow to enter the temporary storage cavity 101 first, the sewage tank 100 further comprises a sewage inlet pipeline 70. One end of the sewage inlet pipeline 70 is connected to the air inlet end 10a, and the other end extends into the temporary storage cavity 101. In this way, external gas or sewage can first enter the temporary storage cavity 101 under the conduction of the sewage inlet pipeline 70. Of course, the main body 21 of the support 20 can also be provided with a corresponding shielding structure to enclose or cover the end of the sewage inlet pipeline 70 in the temporary storage cavity 101, so as to prevent the sewage or liquid droplets from being directly sprayed towards the air outlet end 10b. At the same time, the side of the main body 21 away from the sewage inlet pipeline 70 abuts the inner wall of the tank body 10 to form the second negative pressure channel 105, and the side of the main body 21 towards the sewage inlet pipeline 70 abuts the inner wall of the tank body 10 to form the temporary storage cavity 101. The temporary storage cavity 101 is connected to the air outlet end 10b to form the first negative pressure channel 104. The two negative pressure channels are independent of each other. The first negative pressure channel 104 is in communication with the temporary storage cavity 101, and the second negative pressure channel 105 is in communication with the barrier cavity 102.

[0073] In this way, the space in the tank body 10 is divided into the temporary storage cavity 101, the barrier cavity 102, and the liquid storage cavity 103 by the two partitions. At the same time, the main body 21 of the support 20 forms two negative pressure channels to meet the corresponding space area division.

[0074] Please refer to Figure 6 In some embodiments, in the second direction Y, the bottom end of the temporary storage cavity 101 is in communication with the bottom end of the barrier cavity 102, and the top end of the barrier cavity 102 is in communication with the top end of the liquid storage cavity.

[0075] It can be understood that, in the embodiment, the box 10 needs to be placed in a prone position, then the bottom end of the temporary cavity 101 is close to the end of the ground to be cleaned, and the bottom end of the blocking cavity 102 is also close to the end of the ground to be cleaned. Conversely, the top end of the blocking cavity 102 is the end opposite to the bottom end, and the top end is away from the ground to be cleaned. Similarly, the top end of the liquid storage cavity 103 is also away from the ground to be cleaned.

[0076] The bottom end of the temporary cavity 101 is communicated with the bottom end of the blocking cavity 102, so that the sewage can be quickly sucked into the blocking cavity 102, and the top end of the blocking cavity 102 is communicated with the top end of the liquid storage cavity, so that the sewage can flow into the liquid storage cavity in the normal working position.

[0077] Please refer to Figures 4 to 6 In some embodiments, the first partition 22 is provided with a first water passing structure 20a for communicating the temporary cavity 101 with the blocking cavity 102, and the second partition 30 is provided with a second water passing structure 30a for communicating the liquid storage cavity 103 with the blocking cavity 102, and the first water passing structure 20a and the second water passing structure 30a form a height difference, and the height position of the first water passing structure 20a is lower than that of the second water passing structure 30a.

[0078] It can be understood that the first water passing structure 20a is used to communicate the temporary cavity 101 with the blocking cavity 102, and the structure of the first water passing structure 20a includes but is not limited to a through hole, a notch, and a combination of the two. And the second water passing structure 30a is used to communicate the blocking cavity 102 with the liquid storage cavity 103. The structure of the second water passing structure 30a includes but is not limited to a through hole, a notch, and a combination of the two.

[0079] When the sewage tank 100 is in a prone state, the box 10 should have a first side wall 10c facing the ground to be cleaned and a second side wall 10d away from the ground to be cleaned, then the first water passing structure 20a is formed on the end of the first partition 22 close to the first side wall 10c of the box 10, so that the temporary cavity 101 is communicated with the blocking cavity 102, so that the sewage and airflow enter the blocking cavity 102 from the temporary cavity 101, and the second water passing structure 30a is formed on the end of the second partition 30 facing the second side wall 10d of the box 10, so that when the sewage tank 100 is in a prone state, the first water passing structure 20a and the second water passing structure 30a have a height difference, that is, the first water passing structure 20a is closer to the ground to be cleaned than the second water passing structure 30a.

[0080] When the sewage tank 100 is in a normal working state, sewage enters the blocking cavity 102 from the temporary cavity 101 through the first water passing structure 20a, and flows into the liquid storage cavity 103 from the second water passing structure 30a under the guidance of the second partition 30. When the sewage tank 100 is in an inverted state, if the amount of sewage is relatively small, the sewage is blocked by the second partition 30 and remains in the liquid storage cavity 103. When the amount of sewage is relatively large, the sewage can enter the blocking cavity 102 through the second water passing structure 30a, and then enter the temporary cavity 101 through the first water passing structure 20a. Since the first water passing structure 20a is located at a low position, the liquid level in the temporary cavity 101 and the blocking cavity 102 remains the same or similar when the tank 10 is kept in a horizontal state. In addition, at least part of the gas in the temporary cavity 101 can pass through the liquid storage cavity 103 and the second negative pressure channel 105 to the gas outlet 10b in sequence. In the case that the blocking cavity 102 is connected to the temporary cavity 101, a negative pressure can be generated in the blocking cavity 102 during the process that the gas passes through the blocking cavity 102 and the second negative pressure channel 105 to the gas outlet 10b, so that the sewage in the temporary cavity 101 can be sucked into the blocking cavity 102. At this time, only solid waste and a small amount of sewage are left in the temporary cavity 101, so that the liquid in the temporary cavity 101 can be effectively prevented from surging into the negative pressure source.

[0081] In this way, the water passing structures meet the corresponding space communication requirements, and the two water passing structures form a height difference, that is, the spaces inside the tank 10 are connected in a staggered manner, and the blocking cavity 102 is used to provide a buffer space.

[0082] Please refer to Figure 6 In some embodiments, one end of the first partition 22 is inclined away from the gas outlet 10b, that is, one end of the first partition 22 is inclined toward the gas inlet 10a.

[0083] It can be understood that when the sewage tank 100 is in an inverted state, the tank 10 should have a first side wall 10c facing the ground to be cleaned and a second side wall 10d away from the ground to be cleaned. The first partition 22 has a first end facing the first side wall 10c and a second end facing the second side wall 10d. The first partition 22 is in an inclined state, and the first end is away from the gas outlet 10b, and the second end is close to the gas outlet 10b. The first water passing structure 20a is located at the first end, that is, when the sewage tank 100 is in a normal working state, the first water passing structure 20a is located at the lowest position of the current position of the temporary cavity 101, so that the sewage in the temporary cavity 101 can be discharged into the blocking cavity 102 as much as possible.

[0084] In some embodiments, the second partition 30 is inclined to form one end of the second water passage structure 30a towards the air inlet end 10a.

[0085] Likewise, the second partition 30 should be inclined to have a third end towards the first side wall 10c and a fourth end towards the second side wall 10d, the third end being away from the air inlet end 10a and the fourth end being close to the air inlet end 10a, and the second water passage structure 30a being formed by the fourth end of the second partition 30 and the inner wall of the box 10. In this way, when the sewage tank 100 is in the normal working position, the sewage can quickly flow into the storage cavity 103 under the guidance of the second partition 30, reducing or avoiding the sewage remaining in the blocking cavity 102 when the box 10 is in the normal working position.

[0086] In some embodiments, in the second direction Y, the first partition 22 is inclined to form one end of the first water passage structure 20a away from the air outlet end 10b, and the second partition 30 is inclined to form one end of the second water passage structure 30a towards the air inlet end 10a.

[0087] In this way, when the first partition 22 is inclined in the normal working position, the sewage in the temporary cavity 101 can quickly enter the blocking cavity 102, and the inclined second partition 30 can guide the sewage entering the blocking cavity 102 to enter the storage cavity 103; at the same time, if the sewage in the storage cavity 103 enters the blocking cavity 102 due to agitation, it will also flow back into the storage cavity 103 along the second partition 30 due to the inclination of the second partition 30. In addition, due to the inclination of the second partition 30, the side of the second partition 30 towards the air inlet end 10a forms a certain buffer area with the first side wall 10c, thereby reducing the probability of sewage entering the temporary cavity 101 or the second negative pressure channel 105 due to agitation.

[0088] Please refer to Figure 5 In some embodiments, the sewage tank 100 comprises a filter 40, which is arranged on the first partition 22 and covers the first water passage structure 20a.

[0089] It can be understood that the filter 40 is used to block solid particles, impurities and the like in the sewage, and the filter 40 can be filter cotton, filter screen, or a combination of filter cotton and filter screen.

[0090] For example, the filter 40 can be a structural member adapted to the contour of the first partition 22, the support 20 has a pivoting section, and the filter 40 is installed on the support 20 in a pivoting manner, and the filter 40 covers the first water passage structure 20a. The pivoting manner facilitates the user to remove the support 20 for cleaning.

[0091] Thus, the filter 40 is used to separate the particulate matters, impurities, etc. in the sewage, and to keep the particulate matters, impurities, etc. in the temporary storage cavity 101, so as to reduce the difficulty of cleaning the liquid storage cavity 103 and the blocking cavity 102 to a certain extent.

[0092] In other embodiments, the filter 40 is only covered on the first water passing structure 20a. For example, similar to a cover, the filter is sleeved on the first water passing structure 20a.

[0093] Of course, in other embodiments, the filter can also be arranged on the second partition 30, and the filter is also used to block the second water passing structure 30a. Similarly, the filter is used to separate the particulate matters, impurities, etc. in the sewage, and to keep the particulate matters, impurities, etc. in the blocking cavity 102, so as to reduce the difficulty of cleaning the liquid storage cavity 103 to a certain extent.

[0094] Please refer to Figure 2 and Figure 4 In some embodiments, in the second direction Y, the second negative pressure channel 105 is arranged above the first negative pressure channel 104, and the second negative pressure channel 105 is arranged away from the first water passing structure 20a, the first negative pressure channel 104 has a first air outlet 106 which is in communication with the air outlet end 10b, and the second negative pressure channel 105 has a second air outlet 107 which is in communication with the blocking cavity 102.

[0095] It can be understood that the second negative pressure channel 105 and the first negative pressure channel 104 should be separated by an entity structure. Here, the two negative pressure channels can be formed by corresponding pipelines, or can be formed by the inner wall of the box 10.

[0096] When the box 10 is in the prone position, the second negative pressure channel 105 is at the second side wall 10d of the box 10 and is arranged away from the first water passing structure 20a, so as to reduce or avoid the probability that the sewage flowing from the first water passing structure 20a into the blocking cavity enters the second negative pressure channel 105.

[0097] When the negative pressure source works and the air outlet end 10b performs suction, part of the gas entering the box 10 enters the temporary storage cavity 101, is then transmitted through the first negative pressure channel 104, and is finally discharged from the first air outlet 106 to the air outlet end 10b. Another part of the gas enters the temporary storage cavity 101, enters the blocking cavity 102 through the first water passing structure 20a, enters the second negative pressure channel 105 through the second air outlet 107, and is finally also discharged to the air outlet end 10b.

[0098] Thus, the gas entering the box 10 from the air inlet end 10a, one part sequentially passes through the temporary storage cavity 101, the first negative pressure passage 104, and then is discharged from the first air outlet 106 to the air outlet end 10b, and the other part sequentially passes through the temporary storage cavity 101 and the blocking cavity 102, and then is discharged from the second air outlet 107 into the second negative pressure passage 105, and finally reaches the air outlet end 10b. The two parts of the gas are combined at the air outlet end 10b or before reaching the air outlet end 10b.

[0099] Please refer to Figures 4 to 7 In some embodiments, the sewage tank 100 comprises a baffle 50, which is arranged in the blocking cavity 102 and located at the second air outlet 107.

[0100] The baffle 50 is arranged on the first partition 22, or the baffle 50 is arranged on the second partition 30.

[0101] It can be understood that the baffle 50 is used to block the second air outlet 107, so that the gas can enter the second negative pressure passage 105, and the water splashes or water vapor are prevented from entering the second negative pressure passage 105.

[0102] In actual use, the baffle 50 can be arranged on the first partition 22 or the second partition 30. For example, the baffle 50 can be integrally formed on the first partition 22 or the second partition 30. Of course, it can also be arranged on the first partition 22 or the second partition 30 by other connection methods.

[0103] Thus, the baffle 50 is used to block the second air outlet 107, so that the gas can enter the second negative pressure passage 105, and the water splashes or water vapor are prevented from entering the second negative pressure passage 105.

[0104] Please refer to Figure 7 In some embodiments, the baffle 50 is arranged to be inclined towards the direction away from the second air outlet 107 at the opposite ends along the length direction of the baffle 50.

[0105] Thus, the baffle 50 is arranged to be inclined towards the direction away from the second air outlet 107 at the opposite ends along the length direction of the baffle 50.

[0106] Please refer to Figures 4 to 6 In some embodiments, the second partition 30 comprises a partition plate 31 and a surrounding edge 32 arranged on the partition plate 31, the partition plate 31 is detachably connected to the inner wall of the box 10, and the surrounding edge 32 is formed by extending the side of the partition plate 31 towards the air inlet end 10a.

[0107] It can be understood that the partition plate 31 is the main part of the second partition 30, mainly plays a partitioning role, and the partition plate 31 can be directly or indirectly arranged on the inner wall of the box body 10 to divide the inside of the box body 10 into the blocking cavity 102 and the liquid storage cavity 103. The detachable connection form of the partition plate 31 and the box body 10 can be clamping, plug-in, and threaded connection, etc.

[0108] The enclosing edge 32 should be enclosed on the edge side of the partition plate 31 to form a pressure relief space with the partition plate 31, so that the surge phenomenon can be effectively reduced.

[0109] Please refer to Figures 4 to 6 In some embodiments, the second partition 30 further comprises a support column 33 arranged on the partition plate 31, the support column 33 is connected to the main body 21, the sewage tank 100 comprises a liquid level detection piece 60, the liquid level detection piece 60 has a first liquid level detection position 61, the liquid level detection piece 60 is inserted into the support main body and penetrates the partition plate 31, and the first liquid level detection position 61 is located in the liquid storage cavity 103.

[0110] It can be understood that the partition can be connected with the first partition 22 through the support column 33, or connected with the inner wall of the box body 10, so as to maintain the stability of the arrangement of the partition in the box body 10.

[0111] For example, as Figures 4 to 7 shown, the number of support columns 33 is two, and the number of liquid level detection pieces 60 is also two. When the first liquid level detection position 61 of the two liquid level detection pieces 60 is in contact with the sewage, a power circuit is formed to obtain the storage condition of the current sewage in the liquid storage cavity 103. In addition, when the box body 10 is in a prone position, the height of the first liquid level detection position 61 should be lower than the height of the second water passing structure 30a. Here, the height refers to the height from the ground when the box body 10 is in the prone position. When the liquid surface of the sewage in the liquid storage cavity 103 approaches the second water passing structure 30a, the first liquid level detection position 61 is submerged by the sewage to form a power circuit, so as to prompt the user to pour the sewage through sound, light or combination of sound and light.

[0112] In this way, the liquid detection piece is fixed through the support column 33, and the first liquid level detection position 61 of the liquid detection piece is used to detect the liquid level of the sewage in the liquid storage cavity 103, so as to remind the user to pour the sewage in time.

[0113] In other embodiments, the first liquid level detection piece 61 is arranged close to the second water passing structure 30a on the second partition 30.

[0114] In this way, when the sewage tank is used, the wall surface of the box body 10 away from the second water passing structure 30a is inclined relative to the surface to be cleaned, that is, the sewage tank is in an inclined state. It is more appropriate to arrange the first liquid level detection position 61 at the end away from the surface to be cleaned, and the liquid level detection is more accurate.

[0115] Please refer to Figure 6 and Figure 7 In some embodiments, the liquid level detection piece 60 further has a second liquid level detection position 62, and the support column 33 is provided with a notch 33a, and the second liquid level detection position 62 is exposed in the blocking cavity 102 through the notch 33a.

[0116] It can be understood that the second liquid level detection position 62 is exposed in the blocking cavity 102, and is used to detect the sewage storage condition in the blocking cavity 102, that is, when the sewage in the blocking cavity 102 submerges the second liquid level detection position 62, an energized circuit is also formed.

[0117] Here, the first liquid level detection position 61 and the second liquid level detection position 62 can be at the same horizontal height, or can be at different horizontal heights, and compared with the blocking cavity 102, the sewage is preferentially stored in the liquid storage cavity 103, so that the logic of the liquid level detection piece 60 for prompting the user to pour the sewage can be to prompt when the first liquid level detection position 61 is in the energized circuit, or can be to prompt when both the first liquid level detection position 61 and the second liquid level detection position 62 are in the energized circuit.

[0118] In this way, the second liquid level detection position 62 is mainly used to detect the liquid level condition of the sewage in the blocking cavity 102 in the prone state, so as to remind the user to pour the sewage in time.

[0119] In other embodiments, when the sewage tank is in the prone attitude position, the blocking cavity 102 can also be directly used to store sewage, that is, after the negative pressure environment in the blocking cavity 102 is formed by using the second negative pressure channel 105, the sewage in the temporary cavity 101 can also be sucked into the blocking cavity 102 and temporarily stored in the blocking cavity 102 in the prone attitude position. At this time, the second liquid level detection position 62 is used to detect the liquid level condition in the blocking cavity 102, that is, when the storage amount of the sewage exceeds the second liquid level detection position 62, the user is prompted that the blocking cavity 102 has reached the water storage limit at present and needs to be poured. Then, the user can choose to place the sewage tank in the normal working attitude position state, so that the sewage flows from the blocking cavity 103 into the liquid storage cavity 103, thereby satisfying that the sewage tank can continue to be used in the prone attitude position until the first liquid level detection position 61 detects that the storage of the liquid storage cavity 103 reaches the limit.

[0120] In a second aspect, the embodiments of the present application also provide a cleaning device, which comprises a cleaning main body and the above-mentioned sewage tank 100, and the sewage tank 100 is arranged on the cleaning main body.

[0121] Specifically, the sewage tank 100 is detachably installed on the cleaning body. Of course, the cleaning device also comprises a floor brush assembly arranged on the cleaning body and a fan assembly arranged on the cleaning body, the fan assembly is started to form a negative pressure, and the sewage and fixed impurities are sucked into the sewage tank 100 through the floor brush assembly for temporary storage. Then, the sewage tank 100 is detached from the cleaning body, the inner wall of the tank body 10 of the sewage tank 100 is cleaned, and then the sewage tank 100 is reinstalled in the cleaning body for next use. Of course, the cleaning device can also be used with a cleaning base station to realize automatic sewage discharge of the sewage tank 100, self-cleaning of the floor brush assembly, charging of the cleaning device and the like through the cleaning base station.

[0122] The cleaning device provided in the application has higher use safety of the fan module on the basis of the sewage tank 100.

[0123] The above is only a preferred embodiment of the application, and is not used to limit the application. Any modification, equivalent replacement and improvement within the spirit and principle of the application shall be included in the protection scope of the application.
