Description

Technical Field

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

[0002] With the development of floor scrubber technology, floor scrubbers can support 180° flat lying, changing the overall vertical height of the floor scrubber, allowing the floor scrubber to reach into low spaces such as under beds and sofas for cleaning.

[0003] However, in the related art, the sewage bucket on the floor scrubber is prone to cause sewage to directly enter the negative pressure source when it is lying flat, or the water surface is too close to the negative pressure port of the sewage bucket when it is lying flat, resulting in poor gas-liquid separation effect. Water vapor is more easily sucked into the negative pressure source along with the negative pressure airflow, thereby affecting the service life of the negative pressure source.

[0004] At the same time, the sewage inlet of the existing sewage barrel is generally arranged at the bottom of the sewage barrel and extends toward the top to form a sewage inlet pipe. The sewage flows out from the liquid outlet rapidly along the sewage inlet of the sewage inlet pipe and directly rushes to the wall surface inside the sewage barrel to collide with excessive water mist, thereby increasing the possibility of the negative pressure source inhaling water vapor.

[0008] Optionally, the separation element has a first bottom wall provided with a plurality of through holes, and portions of the two side walls close to the first bottom wall are provided with a plurality of through holes.

[0009] Optionally, the sewage bucket further includes a sewage inlet pipe; the liquid outlet of the sewage inlet pipe is located above the through hole.

[0010] Optionally, the separator has a first opening opposite to the sewage inlet, and the separator seals the first opening by abutting against the partition.

[0011] Optionally, the separator has a first rear wall opposite to the sewage inlet, and the separator abuts against the partition through the first rear wall.

[0012] Optionally, the sewage inlet pipe is at least partially located outside the barrel body, and the sewage inlet pipe is detachably connected to the barrel body.

[0013] Optionally, the sewage inlet pipe has at least two bends.

[0015] Optionally, the sewage inlet pipe includes a first pipe section extending from its liquid inlet and located below the separation chamber, and a third pipe section located outside the separation chamber.

[0016] To achieve the above-mentioned purpose, the present application further provides a sewage barrel, which comprises: a barrel body, having an opening at the top and a sewage inlet at the upper part of the front wall; a barrel cover, having a negative pressure port, the barrel cover is arranged at the opening and is combined with the barrel body to form a sewage holding chamber; a filter assembly connected to the barrel cover, comprising a partition and a separator, wherein the partition extends downward from the bottom of the barrel cover, the partition is arranged in the top space of the sewage holding chamber, and the two sides of the partition are sealed with the inner wall surface of the barrel body to separate the top space into a separation chamber and a liquid storage chamber isolated from each other front and back; the separator abuts against the partition and is located in the separation chamber, the separator at least partially surrounds the sewage inlet, and the separator is at least partially located between the negative pressure port and the sewage inlet, and a first air duct connected to the negative pressure port is formed between the separator and the side wall of the barrel body.

[0017] Optionally, the separator has a first side wall, a second side wall, a first top wall and a first bottom wall, wherein the first side wall, the second side wall, the first top wall and the first bottom wall are clamped front and back between the separator and the front wall of the barrel body, and the first side wall and the second side wall cooperate with their respective adjacent side walls of the barrel body to form a first air duct; the first top wall is arranged between the tops of the first side wall and the second side wall, and the first top wall is located between the negative pressure port and the sewage inlet, and is located above the first top wall and forms a second air duct with the side walls of the barrel body, and the first air duct is connected to the second air duct; the first bottom wall, and the parts of the first side wall and the second side wall adjacent to the first bottom wall are provided with a plurality of through holes.

[0018] It can be seen that the technical solution provided by the present application is to set a partition in the top space of the dirt holding chamber, and the partition is used to divide the dirt holding chamber into a separation chamber and a liquid storage chamber that are isolated from each other. In this way, when the cleaning device is in a flat state, the sewage in the sewage bucket is located below the partition under the action of gravity, and the negative pressure port is located above the partition, so that the partition separates the sewage from the negative pressure port, avoiding the possibility that the sewage in the sewage bucket flows into the negative pressure source through the negative pressure port, and the setting of the partition also extends the distance between the negative pressure port and the sewage located below the partition, thereby reducing the possibility that the sewage is adsorbed by the negative pressure and enters the negative pressure source through the negative pressure port, thereby improving the water vapor separation effect.

[0019] Moreover, by arranging a separator in the separation chamber, and surrounding the sewage inlet, the separator is at least partially located between the negative pressure port and the sewage inlet. In this way, the separator is located on the airflow path between the sewage inlet and the negative pressure port, increasing the chance of the separator colliding with water vapor, so that the separator can block the water vapor in the airflow flowing from the sewage inlet to the negative pressure port to reduce the possibility of water vapor entering the negative pressure port. At the same time, the airflow needs to avoid the separator flow, that is, the airflow needs to go through multiple turns and reversals. At each turn and reversal, due to the different masses of liquid and gas, the inertia of liquid and gas is also different, which also makes the liquid and gas separate from water vapor when turning and reversing, thereby improving the water vapor separation effect. It can be understood that multiple turns and reversals of the airflow also extend the airflow path from the sewage inlet to the negative pressure port, increasing the chance of water in the air being separated from the gas under the action of gravity, thereby improving the gas-liquid separation efficiency.

[0020] Furthermore, by forming a first air duct between the separator and the side wall of the barrel body, the cross-sectional area of ​​the first air duct formed by the side surface of the separator and the side wall of the barrel body is smaller than the cross-sectional area of ​​the air duct between the separator and the barrel cover. According to Bernoulli's principle and the continuity equation, when the flow rate is constant, the larger the cross-sectional area, the smaller the flow rate. That is to say, when the airflow flows from the air duct formed by the side surface of the separator and the two side walls to the air duct between the separator and the barrel cover, the flow rate of the airflow decreases, which increases the time of water vapor separation, thereby further increasing the chance of moisture in the air being separated from the gas under the action of gravity, thereby further improving the gas-liquid separation efficiency.

[0041] The cleaning equipment mainly sprays clean water in real time during the cleaning process and recycles the sewage into the sewage bucket to ensure that the roller brush is always clean and avoid the phenomenon of "dirty dragging dirty", thereby improving cleaning efficiency, reducing water stains, and providing a deeper cleaning effect. At the same time, considering that some low areas often need to be cleaned during actual use, such as the bottom areas of furniture such as beds and sofas. Therefore, the cleaning equipment is also equipped with a lying state, so that when it is necessary to clean the low areas, the cleaning equipment can be adjusted to a lying state to facilitate reaching into the low areas for cleaning.

[0042] However, in the related art, when the sewage bucket on the cleaning equipment is lying flat, it is easy for sewage to flow directly into the negative pressure source through the negative pressure port, or when it is lying flat, the water surface is too close to the negative pressure port of the sewage bucket, resulting in poor gas-liquid separation effect, making it easier for water vapor to be sucked into the negative pressure source along with the negative pressure airflow, thereby affecting the service life of the negative pressure source.

[0043] To this end, the present application redesigns the sewage bucket based on the discovery of the above technical problems. Specifically, by setting a downwardly extending partition at the bottom of the bucket cover of the sewage bucket, and using the partition to divide the top space in the sewage bucket into a separation cavity and a liquid storage cavity that are isolated from each other in the front and back, when the cleaning device is in a flat state, the sewage in the sewage bucket is located below the partition, and the negative pressure port is located above the partition, thereby avoiding the possibility of the sewage in the sewage bucket directly flowing into the negative pressure source through the negative pressure port. In addition, the setting of the partition also increases the distance between the negative pressure port and the sewage located below the partition, further reducing the possibility of water vapor entering the negative pressure source.

[0044] At the same time, it is also considered that the distance between the sewage flowing into the sewage inlet and the negative pressure port is too close, which will also increase the possibility of water vapor entering the negative pressure source. For this reason, the present application also adds a separation element in the separation chamber, and sets the separation element between the sewage inlet and the negative pressure port, and a preset distance is left between the separation element and the two side walls of the barrel body. In this way, not only can the airflow path from the sewage inlet to the negative pressure port be extended, but also the opportunity for the water in the air to be separated from the gas under the action of gravity is increased, thereby improving the gas-liquid separation efficiency. In addition, the above-mentioned setting can also allow the airflow from the sewage inlet to the negative pressure port to pass through the small air duct and the large air duct in sequence. In this way, the difference in the cross-sectional area of ​​the small air duct and the large air duct can be utilized. After the airflow enters the large air duct from the small air duct, according to the Bernoulli principle and the continuity equation, it can be known that because the cross-sectional area of ​​the small air duct is smaller than the cross-sectional area of ​​the large air duct, the airflow velocity entering the large air duct is reduced, and the time for water vapor separation is increased, thereby further increasing the opportunity for the water in the air to be separated from the gas under the action of gravity, improving the gas-liquid separation efficiency, and ensuring the service life of the negative pressure source.

[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0046] Please also see Figure 1 to Figure 2 The present application provides a cleaning device, which may include a floor brush 2000 and a body 3000. The body 3000 is connected to the floor brush 2000 through a pivot member. A handle 4000 is provided at the top of the body 3000 for the user to hold. The user can push the body 3000 and the floor brush 2000 to move by holding the handle 4000. The body 3000 may be provided with a detachable sewage bucket 1000. When the sewage bucket 1000 is connected to the body 3000, the sewage bucket 1000 receives and holds the dirt absorbed during the cleaning process of the cleaning device. After the sewage bucket 1000 is full, the sewage bucket 1000 can be disassembled, so as to facilitate the dumping of dirt and the cleaning of the sewage bucket 1000.

[0047] In actual application, the rear side of the body 3000 is provided with an installation position, and the sewage bucket 1000 is installed on the body 3000 through the installation position. The body 3000 can be pivoted relative to the floor brush 2000 to form an angle θ, so that the cleaning device can more easily clean under furniture or in narrow spaces, that is, the body 3000 can be tilted or even lie flat to be supported by the ground to meet the cleaning needs of different heights. In addition, it can also meet the needs of users of different heights, allowing users to use the floor scrubber more flexibly and conveniently, without bending or squatting to easily operate, and at the same time, this design also helps to reduce the physical burden of users during the cleaning process.

[0048] Regarding the specific structure of the sewage bucket 1000, as shown in FIG. Figures 3 to 7 As shown, in an achievable embodiment, the sewage barrel 1000 may include a barrel body 100 and a barrel cover 200, wherein the barrel body 100 has an opening 110 at the top and a sewage inlet 120 located at the upper part of the front wall 130. The barrel cover 200 has a negative pressure port 210, which is arranged at the opening 110 and encloses the barrel body 100 to form a sewage chamber 300, and the negative pressure port 210 is connected to the sewage chamber 300, so that negative pressure is formed in the sewage chamber 300 through the negative pressure port 210. It should be pointed out that the "front" and "rear" directions defined in this application can refer to Figure 3 Front and back views shown.

[0049] In actual application, after the sewage bucket 1000 is connected to the body 3000, the sewage inlet 120 is connected to the floor brush 2000, and the negative pressure port 210 is connected to the negative pressure source on the body 3000, so that the negative pressure source forms a negative pressure in the dirt holding chamber 300 through the negative pressure port 210, thereby using the negative pressure difference between the inside and outside to suck dirt from the floor brush 2000, and allowing the dirt to enter the sewage bucket 1000 through the sewage inlet 120. After the sewage bucket 1000 is separated from the body 3000, the user can remove the bucket cover 200 from the bucket body 100 to expose the opening 110, so that the dirt in the dirt holding chamber 300 can be poured out through the opening 110.

[0050] In this embodiment, the sewage barrel 1000 may further include a filter assembly 400 for filtering dirt entering through the sewage inlet 120. The filter assembly 400 is connected to the barrel cover 200, so that when the barrel cover 200 is removed from the barrel body 100, the filter assembly 400 can be taken out of the barrel body 100 together with the barrel cover 200, so as to facilitate the dumping of dirt in the dirt holding chamber 300.

[0051] Among them, the filter assembly 400 may include a partition 410. The partition 410 extends downward from the bottom of the barrel cover 200, and the partition 410 is arranged in the top space 330 of the dirt holding chamber 300, and the two sides of the partition 410 are sealed with the inner wall surface of the barrel body 100 to separate the top space 330 into a separation chamber 310 and a liquid storage chamber 320 isolated from each other in the front and back. In other words, the separation chamber 310 is located in front of the partition 410, and the separation chamber 310 is connected to the dirt inlet 120 and the negative pressure port 210, and the liquid storage chamber 320 is located behind the partition 410. In this way, Figure 4 As shown, when the cleaning device is in a lying state, the sewage in the sewage bucket 1000 is located below the partition 410 (in the bottom space of the liquid storage chamber 320 and the sewage holding chamber 300) under the action of gravity, and the negative pressure port 210 is located above the partition 410, so that the partition 410 isolates the sewage from the negative pressure port 210, avoiding the possibility of the sewage in the sewage bucket 1000 flowing into the negative pressure source through the negative pressure port 210, and the setting of the partition 410 also extends the distance between the negative pressure port 210 and the sewage located below the partition 410, thereby reducing the possibility of the sewage being adsorbed by the negative pressure and entering the negative pressure source through the negative pressure port 210, thereby improving the water vapor separation effect.

[0052] The filter assembly 400 may further include a separator 420, the separator 420 abuts against the partition 410 and is located in the separation chamber 310, the separator 420 at least partially surrounds the sewage inlet 120, and the separator 420 is at least partially located between the negative pressure port 210 and the sewage inlet 120. In other words, the separator 420 is located on the airflow path between the sewage inlet 120 and the negative pressure port 210, increasing the chance of the separator 420 colliding with water vapor, so that the separator 420 can block the water vapor in the airflow flowing from the sewage inlet 120 to the negative pressure port 210, so as to reduce the possibility of water vapor entering the negative pressure port 210.

[0053] At the same time, the airflow needs to avoid the separation element 420, that is, the airflow needs to go through multiple turns and reversals. At each turn and reversal, due to the different masses of the liquid and the gas, the inertia of the liquid and the gas is also different, which makes the liquid and the gas separate from each other when turning and reversing, thereby improving the water vapor separation effect. In addition, it can be understood that multiple turns and reversals of the airflow also extend the airflow path from the sewage inlet 120 to the negative pressure port 210, increasing the chance of water in the air being separated from the gas under the action of gravity, thereby improving the gas-liquid separation efficiency.

[0054] Further, such as Figure 7As shown, a first air duct 426 connected to the negative pressure port 210 is formed between the separator 420 and the side wall 140 of the barrel body 100. Specifically, a preset distance is left between the separator 420 and the side wall 140 of the barrel body 100. When the negative pressure source in the cleaning device is working, the airflow entering through the sewage inlet 120 can first flow through the first air duct 426 formed by the side of the separator 420 and the side wall 140 of the barrel body 100, and then flow through the air duct between the separator 420 and the barrel cover 200, and finally flow from the negative pressure port 210 to the negative pressure source.

[0055] It is understandable that since the separator 420 occupies part of the space between the side wall 140 of the barrel body 100, the cross-sectional area of ​​the air duct formed by the side of the separator 420 and the side wall 140 of the barrel body 100 is smaller than the cross-sectional area of ​​the air duct between the separator 420 and the barrel cover 200. According to Bernoulli's principle and the continuity equation, when the flow rate is constant, the larger the cross-sectional area, the smaller the flow rate. That is to say, when the airflow flows from the air duct formed by the side of the separator 420 and the side wall 140 of the barrel body 100 to the air duct between the separator 420 and the barrel cover 200, the flow rate of the airflow decreases, which increases the time of water vapor separation, thereby further increasing the chance of moisture in the air being separated from the gas under the action of gravity, thereby improving the gas-liquid separation efficiency. At the same time, the air duct formed between the separator 420 and the side wall 140 of the barrel body 100 fully utilizes the width of the barrel body 100, and the width of the air duct between the separator 420 and the barrel cover 200 is the width of the space formed by the side wall 140 of the barrel body 100, which fully and effectively utilizes the side wall of the barrel body 100 to maximize the cross-sectional area of ​​the air duct, effectively ensuring the effect of water vapor separation.

[0056] In actual application, when the cleaning device is working, the negative pressure source in the body 3000 works, and negative pressure is formed in the dirt holding chamber 300 through the negative pressure port 210. Under the action of negative pressure, the sewage generated during the cleaning process of the floor brush enters the dirt holding chamber 300 through the sewage inlet 120. At this time, the sewage is blocked by its own gravity and the separation member 420, and then flows along the dirt holding chamber 300. Figure 4 The arrow direction shown flows from the end of the partition 410 (i.e., the end of the partition 410 away from the barrel cover 200) to the bottom space of the liquid storage cavity 320 and the dirt holding chamber 300. Figure 7 In the direction of the arrow shown, the sucked gas flows downward under the obstruction of the separator 420 to bypass the partition 410, and then moves upward to flow through the air duct formed by the separator 420 and the side wall 140 of the barrel body 100, thereby forming an air flow shape similar to a "W" shape. Then, the airflow in the air duct formed by the separator 420 and the side wall 140 of the barrel body 100 flows into the air duct between the separator 420 and the barrel cover 200, and then gathers at the negative pressure port 210 to form an inverted "V" shaped air flow shape. Finally, it flows to the negative pressure source, and the negative pressure source discharges the gas from the cleaning device.

[0057] Regarding the specific structure of the separation member 420, Figure 7 and Figure 8 As shown, in an achievable embodiment, the separator 420 can be constructed as a generally inverted U-shaped structure. Specifically, the separator 420 has two opposite side walls and a first top wall 423 connecting the two side walls, and the two side walls and the corresponding side walls of the barrel body 100 form the above-mentioned first air duct 426. For the convenience of description, the two side walls of the separator 420 are defined as a first side wall 421 and a second side wall 422, that is, the separator 420 has a first side wall 421, a second side wall 422 and a first top wall 423. Among them, the first side wall 421, the second side wall 422 and the first top wall 423 are clamped front and back between the partition 410 and the front wall 130 of the barrel body 100, and the first side wall 421 and the second side wall 422 cooperate with their respective corresponding side walls 140 of the barrel body 100 to form a first air duct 426; the first top wall 423 is arranged between the tops of the first side wall 421 and the second side wall 422, and the first top wall 423 is located between the negative pressure port 210 and the sewage inlet 120.

[0058] The sewage bucket also includes a second air duct 427 formed by the side wall of the barrel body 100 and connected to the first air duct 426 and the negative pressure port 210. Specifically, the side wall 140 of the barrel body 100 located above the first top wall 423 constitutes the second air duct 427, that is, the air duct between the above-mentioned separator 420 and the barrel cover 200. Correspondingly, the gas entering the sewage chamber 300 through the sewage inlet 120 then flows to the negative pressure port 210 through the first air duct 426 and the second air duct 427 in sequence, thereby realizing that the air flow carrying water vapor in the above-mentioned air flow path is bent multiple times to achieve water vapor separation, and the water vapor flow speed is reduced by the change of the cross-sectional area of ​​the first air duct 426 and the second air duct 427 on the inverted "V"-shaped air flow path, thereby reducing the probability of liquid being directly sucked into the negative pressure source.

[0059] In practical applications, the connection between the outer surfaces of the first side wall 421 , the second side wall 422 and the first top wall 423 may adopt an arc transition to reduce the noise caused by the gas impacting the separator 420 .

[0060] In another optional embodiment, on the basis that the above-mentioned separator 420 is configured as an inverted "U"-shaped structure, the separator 420 can also have a first bottom wall 424, the sewage inlet 120 is located between the first bottom wall 424 and the first top wall 423, and the first bottom wall 424 is arranged between the bottoms of the first side wall 421 and the second side wall 422. In other words, the separator 420 can be configured as an annular structure. Accordingly, the first bottom wall 424, the portion of the first side wall 421 adjacent to the first bottom wall 424, and the portion of the second side wall 422 adjacent to the first bottom wall 424 are provided with a plurality of through holes 428, so that the sucked gas can flow out from the separator 410 into the first air duct 426 through the through holes 428 of the first side wall 421 and the second side wall 422, and then enter the second air duct 427, so that the above-mentioned "W"-shaped + inverted "V"-shaped specific air flow shape can also be achieved to improve the water vapor separation effect.

[0061] Furthermore, it is worth mentioning that by providing the first bottom wall 424 with the through hole 428, the liquid in the dirt entering from the sewage inlet 120 can flow through the through hole 428 of the first bottom wall 424, and continue as described above. Figure 4 The liquid flows in the direction of the arrow shown to the liquid storage chamber 320 and the bottom space. The solids in the dirt are blocked by the first bottom wall 424 and retained in the separator 420, thereby achieving the solid-liquid separation effect, avoiding the problem that the solid dirt is deposited at the bottom of the bottom space and is difficult to discharge, or the solid dirt is dumped together with the liquid dirt and blocks the sewer. In this way, the separation effect of water vapor separation can be improved through a separator 420, and solid-liquid separation can be achieved, simplifying the structure of the sewage bucket 1000 and reducing production costs.

[0062] In actual application, when cleaning the sewage bucket 1000, as the user removes the bucket cover 200, the bucket cover 200 can be detached from the sewage chamber 300 together with the separator 420. Accordingly, the solid dirt in the separator 420 is taken out from the sewage chamber 300, thereby facilitating the user to classify and clean the solid dirt and liquid dirt, and avoiding the problem of solid dirt being dumped together with liquid dirt to clog the sewer.

[0063] like Fig. 9 As shown, in a feasible embodiment, the separator 420 has a first opening 429 opposite to the sewage inlet 120, and the separator 420 seals the first opening 429 by abutting against the partition 410, so that solid dirt can be retained in the area surrounded by the separator 420, preventing the dirt from flowing out through the abutment gap between the separator 420 and the partition 410.

[0064] like Figure 6As shown, in another optional embodiment, the above-mentioned separator 420 may also have a first rear wall 425 opposite to the sewage inlet 120, and the separator 420 is abutted against the partition 410 through the first rear wall 425, so that the first side wall 421, the second side wall 422 and the first top wall 423 are connected by the first rear wall 425, or the first side wall 421, the second side wall 422, the first top wall 423 and the first bottom wall 424 are connected by the first rear wall 425, so as to improve the overall structural strength of the separator 420 and ensure the service life of the separator 420.

[0065] Furthermore, compared to the previous embodiment in which the separator 420 abuts against the partition 410 to utilize the partition 410 to seal the first opening 429, the present embodiment is equivalent to setting a first rear wall 425 to seal the first opening 429. In this way, the abutment gap between the separator 420 and the partition 410 can be isolated outside the area surrounded by the separator 420, thereby preventing dirt entering the separator 420 from the sewage inlet 120 from being blocked in the abutment gap between the separator 420 and the partition 410, thereby affecting the user experience.

[0066] like Figure 3 As shown, in an achievable embodiment, the sewage bucket 1000 further includes a sewage inlet pipe 500, which is used to connect the floor brush 2000 and the sewage inlet 120, so that the dirt from the floor brush 2000 can flow into the sewage inlet 120 through the sewage inlet pipe 500. Accordingly, the top of the sewage inlet pipe 500 extends into the separator 420 through the sewage inlet 120, and the liquid outlet 520 at the top of the sewage inlet pipe 500 is located above the through hole 428 of the first side wall 421 and the second side wall 422 in a direction parallel to the center line of the barrel body 100. In actual application, the bottom end of the sewage inlet pipe 500 is provided with a liquid inlet 510, which is connected to the floor brush 2000, so that the dirt can enter the separation chamber 310 through the floor brush 2000 and the sewage inlet pipe 500.

[0067] At the same time, it can be understood that the liquid outlet 520 is located above the through hole 428 of the first side wall 421 and the second side wall 422, not only to achieve the above-mentioned "W" shape + inverted "V" shape of the specific water vapor separation air flow shape, but also to increase the distance between the liquid outlet 520 and the first bottom wall 424, so as to increase the capacity of solid dirt to be accommodated, and avoid solid dirt clogging the liquid outlet 520 and affecting the normal dirt suction work.

[0068] Considering that in the actual use of the cleaning device, the cleaning device often encounters long dirt (such as hair, wire harness, etc.) or other dirt with high adhesion, these dirt may adhere to the inner wall of the sewage inlet pipe 500, or even block the sewage inlet pipe 500, and the sewage inlet pipe 500 is usually integrated with the barrel body 100, so it is difficult to clean the inner wall of the sewage inlet pipe 500. In order to solve the above problems, Figure 3 and Fig.10 As shown, in an achievable embodiment, the sewage inlet pipe 500 is at least partially located outside the barrel body 100, and the sewage inlet pipe 500 is detachably connected to the barrel body 100. In this way, when the inner wall surface of the sewage inlet pipe 500 needs to be cleaned, the sewage inlet pipe 500 can be removed from the barrel body 100 alone, thereby facilitating the cleaning operation.

[0069] In practical applications, a recess 600 may be provided on the outer wall of the barrel body 100, and the sewage inlet pipe 500 may be detachably connected to the recess 600, so that the sewage inlet pipe 500 is stored in the recess 600 to prevent the sewage inlet pipe 500 from being separated from the barrel body 100 and occupying additional volume. Accordingly, the first bottom wall 424 is provided with a notch to avoid the recess 600.

[0070] In order to further improve the dirty gas-liquid separation effect, such as Fig.10 As shown, in an achievable implementation, the sewage inlet pipe 500 may have at least two bends, so that the multiple bends of the sewage inlet pipe 500 can make the sucked airflow have multiple turns in the sewage inlet pipe 500, thereby utilizing the different inertia of water vapor to achieve a water vapor separation effect. In addition, the multiple bends of the sewage inlet pipe 500 can also increase the length of the flow path of the airflow in a limited space, thereby increasing the duration of the water vapor separation process and further improving the water vapor separation effect.

[0071] In this embodiment, the sewage inlet pipe 500 may have one bend, two bends, three bends, or four bends, etc. Taking the sewage inlet pipe 500 having three bends as an example, the sewage inlet pipe 500 has four pipe sections that are interconnected, namely, the first pipe section 501, the second pipe section 502, the third pipe section 503, and the fourth pipe section 504. Correspondingly, the above-mentioned recess 600 may include a first recessed portion 601, a second recessed portion 602, a third recessed portion 603, and a fourth recessed portion 604 that are sequentially connected. The first recessed portion 601 is used to accommodate the first pipe segment 501, and the first recessed portion 601 can extend upward from the bottom surface of the barrel body 100, and the first pipe segment 501 is located below the separation cavity 310. The second recessed portion 602 is used to accommodate the second pipe segment 502, and the second recessed portion 602 can be bent relative to the first recessed portion 601 and extend radially outward and upward in parallel along the barrel body 100. The third recessed portion 603 is used to accommodate the third pipe segment 503, and the third pipe segment 503 is located outside the separation cavity 310. The third recessed portion 603 can be bent relative to the second recessed portion 602 and extend upward. The fourth recessed portion 604 is used to accommodate the fourth pipe segment 504, and the fourth recessed portion 604 can be bent relative to the third recessed portion 603 and extend radially inward along the barrel body 100 into the sewage inlet 120.

[0072] In actual application, dirt from the floor brush 2000 follows the airflow and enters the first pipe section 501 from the liquid inlet 510, and passes through the second pipe section 502, the third pipe section 503 and the fourth pipe section 504 in sequence, and finally enters the separator 420 from the fourth pipe section 504 through the liquid outlet 520. There is an angle between the axis of the first pipe section 501 and the second pipe section 502, and the airflow carrying dirt flows from the first pipe section 501 into the second pipe section 502, and the airflow direction changes for the first time. There is an angle between the axis of the second pipe section 502 and the third pipe section 503, and the airflow flows from the second pipe section 502 into the third pipe section 503, and the airflow direction changes for the second time. There is an angle between the axis of the third pipe section 503 and the fourth pipe section 504, and the airflow flows from the third pipe section 503 into the fourth pipe section 504, and the airflow direction changes for the third time. By providing multiple bends, the sewage changes its flow direction three times from the liquid inlet 510 to the liquid outlet 520, that is, in the sewage inlet pipe 500, so that the liquid and gas in the air flow are fully separated.

[0073] like Figure 4 and Fig. 9As shown, in an achievable embodiment, a baffle 700 is further provided in the dirt holding chamber 300, the baffle 700 is connected to the end of the partition 410, and the baffle 700 extends to the rear of the barrel body 100, and a certain distance is left between the baffle 700 and the inner wall of the barrel body 100. In this way, when the cleaning device is in a flat state, the liquid in the liquid storage chamber 320 and the liquid in the bottom space of the dirt holding chamber 300 can flow mutually, and a certain buffering effect can be played on the liquid flowing mutually between the liquid storage chamber 320 and the dirt holding chamber 300, weakening the waves generated by the dirt moving back and forth between the liquid storage chamber 320 and the dirt holding chamber 300, so that the dirt can be stabilized faster, reducing the impact force on the sewage bucket 1000, and improving the user experience.

[0074] Furthermore, a plurality of buffer holes may be provided on the baffle 700 , so as to utilize the buffer holes to reduce the impact force of dirt on the baffle 700 , thereby ensuring the service life of the baffle 700 and reducing the impact force of dirt on the sewage bucket 1000 through the baffle 700 .

[0075] In practical applications, a gap for liquid flow may be reserved at the connection between the baffle 700 and the partition 410, and / or a gap for liquid flow may be reserved between the baffle 700 and the front wall of the barrel 100, so that the liquid separated by the separator 420 can be Figure 4 As shown, the liquid flows through the liquid gap between the baffle 700 and the partition 410 to the bottom space of the liquid storage chamber 320 and the dirt containing chamber 300 .

[0076] Based on the same inventive concept, the present application also provides a sewage bucket 1000, which can be used as a separate component, integrally installed in a cleaning device and integrally removed from the cleaning device. Specifically, the sewage bucket 1000 may at least include a barrel body 100, a barrel cover 200 and a filter assembly 400, wherein the barrel body 100 has an opening 110 at the top and a sewage inlet 120 at the upper part of the front wall 130. The barrel cover 200 has a negative pressure port 210, and the barrel cover 200 is arranged at the opening 110 and encloses the barrel body 100 to form a sewage chamber 300. The filter assembly 400 connected to the barrel cover 200 includes a partition 410 and a separator 420, wherein the partition 410 extends downward from the bottom of the barrel cover 200, and is disposed in the top space of the dirt holding chamber 300, and both sides of the partition 410 are sealed against the inner wall surface of the barrel body 100 to separate the top space into a separation chamber 310 and a liquid storage chamber 320 that are isolated from each other. The separator 420 abuts against the partition 410 and is located in the separation chamber 310, and the separator 420 at least partially surrounds the dirt inlet 120, and the separator 420 is at least partially located between the negative pressure port 210 and the dirt inlet 120, and a first air duct 426 communicating with the negative pressure port 210 is formed between the separator 420 and the side wall of the barrel body 100.

[0077] Further, the separator 420 has a first side wall 421, a second side wall 422, a first top wall 423 and a first bottom wall 424, wherein the first side wall 421, the second side wall 422, the first top wall 423 and the first bottom wall 424 are clamped between the separator 410 and the front wall 130 of the barrel body 100, and the first side wall 421 and the second side wall 422 cooperate with the side walls 140 of the barrel body 100 adjacent to each other to form a first air duct 426; The first top wall 423 is arranged between the top of the first side wall 421 and the second side wall 422, and the first top wall 423 is located between the negative pressure port 210 and the sewage inlet 120.
