Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a separator, a wastewater tank, and a cleaning device. Background Technology

[0002] As living standards improve, people have increasingly higher requirements for floor cleaning. Currently, the market offers a variety of surface cleaning equipment, such as vacuum cleaners, floor scrubbers, and steam mops, to meet diverse needs. Floor scrubbers, in particular, are convenient and quick, as they can both collect dirt and perform wet cleaning on the surface.

[0003] There are many types of surface cleaning equipment on the market, among which floor scrubbers are attracting more and more attention. They can not only suck up dirt from the ground, but also use running water to clean the surface, resulting in good cleaning effect. However, users have also discovered new problems during the use of floor scrubbers. When cleaning equipment with a wastewater tank is used for gas-liquid separation, the separation is not clean. Wastewater will enter the machine body with the airflow, causing pollution inside the cleaning equipment and damaging the circuit board and battery. Summary of the Invention

[0004] To address the shortcomings of the aforementioned technologies, this invention provides a separator, a wastewater tank, and a cleaning device. The separator is mainly used in the cleaning device and can perform gas-liquid separation on the airflow of the cleaning device, resulting in good gas-liquid separation and improving the service life of the cleaning device.

[0005] On one hand, this application provides a separator disposed at the air outlet of a cleaning device, from which airflow flows out. It includes a separator body, a first filter structure and a second structure, the first filter structure defining a first filter port, the separator body being disposed near the air outlet and being rotatable relative to the air outlet; wherein, airflow enters from the first filter port and flows toward the air outlet, and the second structure is configured to prevent at least a portion of the airflow from the location of the second structure to the air outlet when the separator body rotates.

[0006] The first filter structure includes a plurality of first blades, the separator body is provided with a first support and a second support, the plurality of first blades are disposed between the first support and the second support, and the second structure is disposed on the first support.

[0007] A first annular surface is formed between the inner and outer rings of the first support member, and the plane containing the outer ring of the first support member is higher than the plane containing the inner ring of the first support member.

[0008] The second structure includes a plurality of second blades extending between the outer ring and the inner ring of the first support member; and / or, the thickness h of the second blades gradually increases as they extend from the outer ring to the inner ring.

[0009] A first annular surface is formed between the inner and outer rings of the first support member. The second structure includes a plurality of second blades, which are disposed on the first annular surface. An arc-shaped channel is formed between two adjacent second blades. During the rotation of the separator, the arc-shaped channel is used for airflow to flow from the inside of the separator to the outside, preventing at least part of the airflow from entering the separator from the second blade.

[0010] The second structure includes a plurality of second blades, the upper surface of which is in the same plane or parallel to the surface of the outer ring of the first support member; and / or, at least part of the surface of the upper surface of the second blades coincides with the surface of the outer ring of the first support member.

[0011] A wastewater tank includes, as described above, a wastewater tank body, an internally defined first cavity, the first cavity having a wastewater inlet and an air outlet, a driving member for driving the separating member to rotate, and a bracket disposed on the wastewater tank body for supporting the separating member; wherein, the separating member is at least partially disposed within the first cavity, rotates under the drive of the driving member, performs gas-liquid separation on waste entering the first cavity from the wastewater inlet, throws at least a portion of the liquid off the separating member, and the airflow enters the air outlet from the first filter port.

[0012] The bracket is provided with an annular baffle, the separator is located outside the annular baffle and rotates relative to the annular baffle, the annular baffle at least partially blocks the first filter port, or the suspended end of the annular baffle is lower than the upper surface of the second structure.

[0013] During the rotation of the separator, the annular baffle blocks at least part of the airflow entering from the first filter port. At least part of the blocked airflow enters the location of the second structure. As the separator rotates, the second structure generates airflow flowing to the outside of the separator to prevent airflow from flowing from the location of the second blade to the air outlet.

[0014] The annular baffle has a first surface and a second surface that are perpendicular to each other. The first surface is close to the second structure, and the second surface is close to the inner surface of the separator.

[0015] The annular baffle has a sealed cavity defined by a connecting block. The driving member is disposed within the sealed cavity, and its drive shaft passes through the bottom of the sealed cavity and is connected to the separating member for transmission, driving the separating member to rotate. The second structure includes a plurality of second blades, the extension direction of which is substantially oriented towards the rotation direction of the separating member.

[0016] A cleaning device includes, as described above, a wastewater tank, a floor brush assembly, a floor brush housing, a roller brush assembly for cleaning the surface to be cleaned provided at the front of the floor brush housing, and the wastewater tank is located on the opposite side of the floor brush housing and the roller brush assembly.

[0017] The separator provided by this invention has the following beneficial effects: The separator has a separator body, which itself has a first blade and a second blade. A first filter opening is formed between two adjacent first blades. Airflow enters through the first filter opening, and the separator can rotate under the action of the airflow. Gas-liquid separation is achieved through the first filter opening, resulting in better separation. The separator body is located near the air outlet and can rotate relative to the air outlet. After separation at the first filter opening, the airflow can enter the air outlet and be discharged, improving the gas-liquid separation efficiency. The airflow enters from the first filter opening and flows towards the air outlet. When the second blade rotates with the separator body, the airflow flows out of the separator from the second blade, preventing at least part of the airflow from the location of the second blade to the air outlet, thus improving the separation effect of the separator.

[0024] This embodiment provides a separator 11, as shown in the attached document. Figure 1-16 It is mainly used at the air outlet of cleaning equipment to perform gas-liquid separation, with the airflow exiting from the outlet. The separator 11 includes a separator body 110. (See attached document for reference.) Figure 3 Appendix Figure 11 and attached Figure 12 The separator body 110 is provided with a first filter structure and a second structure. In the embodiment shown in the figure, the first filter structure includes first blades 111. In other embodiments, the first filter structure can also be other structures that can achieve gas-liquid separation during rotation, such as a filter screen structure, etc., which are not limited here. In the embodiment shown in the figure, the second structure includes a plurality of second blades 113. In other embodiments, the second structure can also be other structures that can prevent airflow from the second structure to the air outlet 104 during rotation, that is, structures that can generate airflow in the opposite direction to the flow direction of the suction airflow. A first filter opening 112 is formed between two adjacent first blades 111.

[0025] The separator body 110 is located near the air outlet 104. The separator body 110 is rotatable relative to the air outlet 104. Airflow enters through the first filter port 112 and flows towards the air outlet 104. As the separator body 113 rotates, it prevents at least a portion of the airflow from flowing towards the air outlet 104 from the location of the second blade 113. The separator body 110 can be directly located near the air outlet 104. Alternatively, the separator body 110 can be indirectly located near the air outlet 104, forming a sealed exhaust channel 22 between the separator body 110 and the air outlet 104, thus the separator body 110 is considered to be located near the air outlet 104.

[0026] In this embodiment, the separator body 110 rotates around the air outlet 104 to prevent airflow from directly entering the air outlet 104 from the point where the separator body 110 is close to the air outlet 104. The separator body 110 is provided with a second blade 113. When the separator body 110 rotates, the airflow flows outward from the inside of the separator body 110. After flowing out of the separator body 110, the airflow re-enters through the first filter port 112, thus forming an internal circulation. This prevents at least some water vapor from directly entering the air outlet 104, improving the gas-liquid separation effect and thereby extending the service life of the cleaning equipment.

[0027] Please refer to the appendix again. Figure 11 and attached Figure 12 The separator body 110 may be provided with a first support 114 and a second support 115. Multiple first blades 111 are disposed between the first support 114 and the second support 115. Second blades 113 are disposed on the first support 114. Both the first support 114 and the second support 115 are annular structures. The centers of the first support 114 and the second support 115 are on a straight line. The inner ring diameter of the first support 114 is greater than or equal to the outer ring diameter of the second support 115. A first filter opening 112 is formed between any two first blades 111 at intervals. The first filter opening 112 may be a strip-shaped opening. The first filter opening 112 extends from the first support 114 to the second support 115. The first filter openings 112 are of substantially the same size. The first support 114 is provided with a first annular surface 118. The first annular surface 118 has a slope.

[0028] A first annular surface 118 is formed between the inner ring 116 and the outer ring 117 of the first support member 114. The plane containing the outer ring 117 of the first support member 114 is higher than the plane containing the inner ring 116 of the first support member 114. The first annular surface 118 is formed as an inclined surface or a curved surface. A second blade 113 is disposed on the first annular surface 118. In one embodiment, the first blade 111 extends along the inner ring 116 of the first support member 114 toward the second support member 115. The first blade 111 extends upward along the outer ring 117 of the second support member 115 and connects with the inner ring of the first support member 114.

[0029] A second blade 113 is provided on the first annular surface 118. The second blade 113 extends between the outer ring 117 and the inner ring 116 of the first support member 114. The second blade 113 may have one end located on the outer ring 117 and the other end located on the inner ring 116. The thickness h of the second blade 113 gradually increases as it extends from the outer ring 117 to the inner ring 116. The thickness h of the second blade 113 gradually decreases as it extends from the inner ring 116 to the outer ring 117. An arc-shaped channel 119 is formed between any two adjacent second blades 113. The arc-shaped channels 119 are of approximately the same size. The sidewalls of the arc-shaped channels 119 may be triangular. The upper surface 1131 of the second blade 113 is on the same plane or parallel to the surface of the outer ring 117. At least part of the surface of the upper surface 1131 of the second blade 113 coincides with the surface of the outer ring 117. The upper surface 1131 is planar and is on the same plane or parallel to the surface of the outer ring 117. The surface where the upper surface 1131 and the outer ring 117 are located can also be a continuous surface. This can reduce the gap between the separator and the air outlet 104, reduce the amount of airflow entering through the gap, and improve the gas-liquid separation effect.

[0030] This embodiment provides a sewage tank 1. (See attached document.) Figure 1-7 The wastewater tank 1 is used for filtering and storing dirt in cleaning equipment. The wastewater tank 1 includes the separator 11 described in the above embodiment. The wastewater tank 1 includes a wastewater tank body 101. A first cavity 102 is defined inside the wastewater tank body 101. A removable top cover 108 is provided on the top of the first cavity 102. The first cavity 101 has a wastewater inlet 103 and an air outlet 104. A drive member 6 and a bracket 2 are also provided inside the first cavity 102. The drive member 6 has a drive shaft 61. The drive shaft 61 is connected to the separator 11 and drives the separator 11 to rotate. The drive member 6 is located inside the bracket 2. The drive shaft 61 passes through the bracket 2 and is connected to the separator 11 in a transmission manner.

[0031] Reference Appendix Figure 6 and attached Figure 7The separator 11 is at least partially disposed within the first cavity 102. The separator 11 may be entirely disposed within the first cavity 102. Alternatively, the separator 11 may be entirely disposed outside the first cavity 102 but connected to it. The separator 11 rotates under the drive of the drive unit 6. The separator 11 separates contaminants entering the first cavity 102 from the inlet 103, throwing out small solid particles and liquids. Airflow enters the outlet 104 from the first filter port 112. The drive unit 6 can be started together with the cleaning equipment; that is, when the cleaning equipment is started, the drive unit 6 drives the separator 11 to rotate, separating the contaminants entering the first cavity 102. In other embodiments, the drive unit 6 can be controlled to start and stop independently. That is, when the cleaning equipment is turned on, the drive unit does not start. When the cleaning equipment is running normally, the drive unit is started only when needed, and the separator 11 rotates to separate the contaminants in the first cavity 102.

[0032] Reference Appendix Figure 12-16 The bracket 2 is provided with an annular baffle 21. The bracket 2 is provided with an exhaust channel 22. The annular baffle 21 and the exhaust channel 22 are respectively located on opposite sides of the bracket 2. The exhaust channel 22 is connected to the air outlet 104. The separator 11 is located outside the annular baffle 21 and rotates relative to the annular baffle 21. The annular baffle 21 at least partially blocks the first filter port 112. The suspended end of the annular baffle 21 is lower than the upper surface of the second structure. During the rotation of the separator 11, the annular baffle 21 blocks at least part of the airflow entering from the first filter port 112. At least part of the blocked airflow enters the location of the second structure. As the separator 11 rotates, the second structure generates airflow flowing outward from the separator 11 to prevent airflow from the location of the second blade 113 to the air outlet 104.

[0033] The annular baffle 21 may have a first surface and a second surface perpendicular to the first surface. The first surface is located on the upper part of the first annular surface. The second surface is located on the inner surface of the separator 11. The first and second surfaces of the annular baffle 21 are not sealed with the separator 11. In one embodiment, refer to the attached drawing. Figure 16 The bracket 2 and the top cover 108 can be integrated into one unit. The one-piece molding of the bracket 2 and the top cover 108 can reduce the possibility of water entering through gaps between disassembled parts.

[0034] In one embodiment, a sealing cavity 23 is defined inside the annular baffle 21 by connecting blocks 24. Air holes 25 are defined between the connecting blocks 24. A drive member 6 is installed within the sealing cavity 23. A drive shaft 6 passes through the bottom of the sealing cavity 23 and is drive-connected to the separator 11. This drive-connection includes direct or indirect connection between the drive shaft of the drive member and the separator; any connection that drives the separator 11 to rotate via the drive member 6 falls within the scope of this application.

[0035] In a preferred embodiment, a first filter screen is spaced apart on the outside of the separator 11. The first filter screen filters the airflow entering the first filter port of the separator 11. The separator 11 is driven to rotate. The extension direction of the second blade 113 is substantially oriented towards the rotation direction of the separator 11.

[0036] Reference Appendix Figure 1-7 This embodiment also provides a wastewater tank 1 for use in cleaning equipment. The wastewater tank 1 includes a wastewater tank body 101. The wastewater tank body 101 internally defines a first cavity 102. The first cavity 102 is provided with a wastewater inlet 103 and an air outlet 104. The first cavity 102 is used to store dirt. Dirt enters the first cavity 102 through the wastewater inlet 103, and the airflow entering the first cavity 102 is separated and flows out through the air outlet 104.

[0037] Reference Appendix Figure 5-7 In this embodiment, the length of the sewage tank body 101 is greater than its height. The width is defined by the direction in which the sewage tank 1 moves forward. A filter device 4 is disposed within the first cavity 102. The filter device 4 includes a shielding portion 41 and a filter portion 42, which are arranged side-by-side along the length of the sewage tank body 101. The filter portion 42 has multiple filter baffles 43. A second filter opening 44 is defined between two adjacent filter baffles 43. The second filter opening 44 allows sewage to pass through while preventing large solid particles from passing through.

[0038] The sewage tank 1 provided in this embodiment has a lower height than the sewage tanks commonly found on the market, and its center of gravity is lower. The filter device 4 is located in the first cavity 102 of the sewage tank body 101. It has a simple structure, is easy to install, has a good filtration effect, and can effectively reduce the problem of sewage backflow in the sewage tank 1.

[0039] Reference Appendix Figure 8-10 The filter device 4 can be integrally formed, with the shielding part 41 and the filter part 44 disposed on essentially the same plane. Here, "one plane" means that the shielding part 41 and the filter part 44 are on the same plane. The shielding part 41 and the filter part 44 can also be stepped or other shaped structures; anything that can be considered to be on the same plane as a whole falls within the scope of this example.

[0040] In the filter device 4, filter baffles 43 extend from one side of the filter section 42 to the other. As the filter baffles 43 extend from one side of the filter section 42 to the other, a recessed area 46 is formed downwards. The recessed area 46 is recessed downwards relative to the side of the filter section 42, forming a space. The recessed area 46 can be used to store solid waste, increasing the storage capacity and preventing solid waste from spilling when the filter device 4 is removed. The size and structure of the multiple filter baffles 43 may not be exactly the same. The width of the filter baffles 43 near the center in its extending direction may be greater than or equal to the width of its two sides. In other embodiments, the width of the filter baffles 43 in its extending direction is substantially the same. At least some of the filter baffles 43 may be arranged parallel to the filter section. At least some of the second filter openings 44 are of different sizes.

[0041] Reference Appendix Figure 5-10 The wastewater tank body 101 is also equipped with a partition plate 5, which is located inside the filter device 4 or the first cavity 102. The partition plate 5, located at the bottom of the first cavity 102, divides and blocks the liquid stored at the bottom of the first cavity 102. During the movement of the cleaning equipment, the wastewater tank 1 reduces the sloshing of the liquid inside the first cavity 102, reducing the damage caused by wastewater backflow to the cleaning equipment. The partition plate 5 can be directly installed inside the first cavity 102. Alternatively, the partition plate 5 can be directly installed on the filter device 4, installed or removed together with the filter device 4 within the first cavity 102. In other embodiments, the partition plate 5 can be a separate, detachable structure within the first cavity 102.

[0042] Reference Appendix Figure 9 The partition plate 5 forms an angle α with the forward direction of the filter device 4. The angle α ranges from 60 to 120 degrees. This angle between the partition plate 5 and the forward direction of the filter device 4 improves the blocking effect of the partition plate 5 on liquid in the forward direction of the wastewater tank 1. When the angle α is 90 degrees in the forward direction of the filter device 4, the partition plate 5 has an even better effect on preventing wastewater sloshing.

[0043] Reference Appendix Figure 6-10 The first chamber 102 is divided into multiple compartments 51 by the partition plate 5, and the compartments 51 are interconnected. This interconnection between compartments 51 improves the liquid storage efficiency within the first chamber 102. The compartments 51 may be interconnected at the bottom, or they may be interconnected through the partition plates 5. The filter device 4 is also equipped with a handle 45, symmetrically positioned on both sides of the filter device 4 body. The handle 45 facilitates the installation or removal of the filter device 4 from the first chamber 102 of the wastewater tank body 101.

[0044] Reference Appendix Figure 1 and attached Figure 2The filter device 4 divides the first chamber 102 into a first receiving chamber 105 and a second receiving chamber 106. The first receiving chamber 105 is located above the second receiving chamber 106. A protruding edge 107 is formed at the connection between the second receiving chamber 106 and the first receiving chamber 105. The protruding edge 107 supports the filter device 4. The first receiving chamber 105 is used to store solid dirt, and the second receiving chamber 106 is used to store liquid dirt.

[0045] In other embodiments, the protrusion 107 may also be formed when the first accommodating cavity 105 and the second accommodating cavity 106 are connected. The inner diameter of the second accommodating cavity 106 is smaller than the inner diameter of the first accommodating cavity 105.

[0046] This embodiment provides a wastewater tank 1 for use in cleaning equipment. (See attached document.) Figure 1 The wastewater tank 1 includes a wastewater tank body 101. The wastewater tank body 101 internally defines a first cavity 102. The first cavity 102 has a wastewater inlet 103 and an air outlet 104. Waste enters the first cavity 102 through the wastewater inlet 103. Filtered airflow is discharged through the air outlet 104. The length of the wastewater tank body 101 is greater than its height. The wastewater tank body 101 includes a separator 11, a support 2, and a baffle 3. The separator 11 has first blades 111. A first filter opening 112 is formed between any two first blades 111. The separator 11 is located within the first cavity 102 and is used for gas-liquid separation of the dirt entering the first cavity 102. The support 2 is located within the first cavity 102 and is used to support the separator 11. The baffle 3 is suspended above the wastewater inlet 103, and an airflow channel 31 is formed on the inner wall of the baffle 3, which guides the dirt entering from the wastewater inlet 103. The opening direction of the airflow channel 31 is away from the separator 11.

[0047] In one embodiment, the separator 11 is further provided with a second blade 113. The separator 11 rotates around the air outlet 104. This prevents airflow from directly entering the air outlet 104 from the point where the separator 11 is close to the air outlet 104. The second blade 113 causes airflow to flow outward from the inside of the separator 11 as the separator 11 rotates, and then re-enter through the first filter port 112, thus forming an internal circulation. This prevents at least some water vapor from entering the air outlet 104, improving the gas-liquid separation effect and extending the service life of the cleaning equipment. The wastewater tank body 101 may also have a top opening. A top cover 108 is provided at the opening. The air outlet 104 is located on the top cover 108. A bracket 2 may be located on the top cover 108. The bracket 2 may be detachably installed on the top cover 108. Alternatively, the bracket 2 may be integrally formed with the top cover 108.

[0048] Dirt enters the first chamber 102 through the inlet 103 and, under the action of the baffle 3, is guided by the airflow channel to flow away from the separator 11. This prevents moisture in the dirt from directly entering the separator 11 and the outlet 104 with the airflow, thus preventing damage to the cleaning equipment.

[0049] Reference Appendix Figure 11-15 The support 2 is equipped with an annular baffle 21. The annular baffle 21 is positioned near the first filter port 112 of the separator 11. The first filter port 112 is at least partially blocked by the annular baffle 21. The separator 11 can rotate around the annular baffle. The sewage tank 1 is also equipped with a drive component 6. The drive component 6 is connected to the separator 11 and drives the separator 11 to rotate. The drive component 6 can be directly connected to the separator 11 through its drive shaft 61 to drive the separator 11 to rotate. The drive component 6 can also drive the separator to rotate through other transmission methods, such as gear sets, swing arms, etc., to separate the gas and liquid in the first cavity 102.

[0050] Reference Appendix Figure 14-16 A sealing cavity 23 may be defined on the bracket 2. The drive member 6 is disposed within the sealing cavity 23. The sealing cavity 23 supports and seals the drive member 6, preventing airflow from entering the drive member 6 and causing damage. In a preferred embodiment, the drive shaft 61 of the drive member 6 passes through the sealing cavity 23 and is connected to the separator 11. The separator 11 rotates under the drive of the drive member 6, separating the gas and liquid in the first cavity 102. The separated liquid is stored at the bottom of the first cavity 102, and the separated gas is discharged from the outlet 104 into the sewage tank 1.

[0051] The wastewater tank 1 also includes a filter device 4. (See attached document for reference.) Figure 7-10 The filtering device 4 includes a shielding portion 41 and a filtering portion 42 arranged horizontally. The shielding portion 41 and the filtering portion 42 can be integrally formed. Alternatively, the shielding portion 41 and the filtering portion 42 can be two independent or interconnected structures arranged in a nearly coplanar manner within the first cavity 102. The filtering device 4 is located within the first cavity 102. The filtering device 4 is located below the separating member 11 and the baffle 3. The separating member 11 and the baffle 3 are substantially on the same plane. The filtering portion 42 is provided with a second filter port 44, which is used for solid-liquid separation of dirt entering the first cavity 102. The separating member 11 is located near the shielding portion 41. The baffle 3 is located near the filtering portion 42.

[0052] The wastewater tank body 101 is also provided with a dividing plate 5, which is substantially perpendicular to the forward direction of the wastewater tank body 101. The dividing plate 5 is located inside the filter device 4 or the first cavity 102. By dividing the liquid stored at the bottom of the first cavity 102, the dividing plate 5 reduces the sloshing of liquid within the first cavity 102 during the movement of the wastewater tank 1 with the cleaning equipment, thus reducing damage to the cleaning equipment caused by upward backflow of wastewater. The dividing plate 5 can be directly installed inside the first cavity 102. Alternatively, the dividing plate 5 can be directly installed on the filter device 4, installed or removed together with the filter device 4 within the first cavity 102. In other embodiments, the dividing plate 5 can be a separate, detachable structure within the first cavity 102.

[0053] Reference Appendix Figure 8-10 The partition plate 5 forms an angle α with the forward direction of the filter device 4. The angle α ranges from 60 to 120 degrees. This angle between the partition plate 5 and the forward direction of the filter device 4 improves the blocking effect of the partition plate 5 on liquid in the forward direction of the wastewater tank 1. When the angle α is 90 degrees in the forward direction of the filter device, the partition plate 5 has an even better effect on preventing wastewater sloshing.

[0054] Reference Appendix Figure 6 The first chamber 102 is divided into multiple compartments 51 by the partition plate 5, and the compartments 51 are interconnected. This interconnection between compartments 51 improves the liquid storage efficiency within the first chamber 102. The compartments 51 may be interconnected at the bottom, or they may be interconnected through the partition plates 5. The filter device 4 is also equipped with a handle 45, symmetrically positioned on both sides of the filter device 4. The handle 45 facilitates the installation or removal of the filter device 4 from the first chamber 102 of the wastewater tank body 101.

[0055] Reference Appendix Figure 10 , 13 and attached Figure 16 The shielding part 41 is provided with a groove 411, and a water level detector 412 is provided in the groove 411 for detecting the water level in the groove 411. The groove 411 is a groove extending downward on the shielding part 41, and the groove 411 can collect at least part of the liquid separated from the separator 11. When the liquid in the groove 411 reaches a specified water level, the water level detector 412 alarms.

[0056] On the other hand, this embodiment also provides another floor brush assembly 100. The floor brush assembly 100 includes a wastewater tank 1. The floor brush assembly 100 also includes a floor brush housing 7. A roller brush assembly 8 for cleaning the surface to be cleaned is provided on the front side of the floor brush housing 7. The wastewater tank 1 is located on the opposite side of the floor brush housing 7 and the roller brush assembly 8. A suction port is provided on the floor brush housing 7 near the roller brush assembly 8, and the suction port is connected to the inlet 103. When the roller brush assembly 8 cleans the surface to be cleaned, the dirt is sucked in by the airflow from the suction port and enters the first cavity 102 of the wastewater tank 1 through the inlet 103. In the first cavity 102, the dirt is separated into solid and liquid by the filter device 4, and the gas and liquid of the airflow are separated by the separator 11. The separated gas is discharged from the air outlet 104, and the liquid is stored at the bottom of the wastewater tank 1.

[0057] The floor brush housing 7 is also equipped with a clean water tank 9, which is located on one side of the waste water tank 1. The clean water tank 9 is removed from or installed on the floor brush housing 7 together with the waste water tank 1. The clean water tank 9 is used to provide clean water to the roller brush assembly 8.

[0058] This embodiment also provides a cleaning device, including, as described above, a wastewater tank 1, a floor brush assembly 100, the floor brush assembly 100 having a floor brush housing 7, the front of the floor brush housing 7 having a roller brush assembly 8 for cleaning the surface to be cleaned, and the wastewater tank 1 being located on the opposite side of the floor brush housing 7 and the roller brush assembly 8.
