Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a rotary separation structure, a wastewater tank, and a cleaning device. Background Technology

[0002] Cleaning equipment, such as floor scrubbers, are household cleaning appliances that combine vacuuming, mopping, and self-cleaning functions. They can handle mixed solid and liquid waste in one go, significantly improving cleaning efficiency.

[0003] In related technologies, cleaning equipment may include a main unit and a wastewater tank connected together, with the main unit equipped with a suction component. When the cleaning equipment is working, the negative pressure generated by the suction component can suck debris and wastewater from the ground into the wastewater tank.

[0004] However, some of the sewage in the sewage tank will enter the suction component of the main unit along with the gas, causing damage to the suction component. Utility Model Content

[0005] This application provides a rotary separation structure, a wastewater tank, and a cleaning device to solve the problem that some wastewater in the wastewater tank enters the suction component along with the gas, causing damage to the suction component.

[0006] In a first aspect, the rotational separation structure provided in this application includes:

[0007] A rotary separation assembly is used to be installed in the wastewater tank of a cleaning device. The rotary separation assembly has at least one drain hole and is configured to rotate to separate a water-air mixture.

[0008] At least one first seal is disposed on the rotary separation assembly corresponding to the drain hole, and the first seal covers the drain hole. The first seal is configured to move relative to the rotary separation assembly to open the drain hole under the action of the rotary separation assembly and the water-air mixture, so that the rotary separation assembly separates the liquid in the water-air mixture and throws it into the sewage tank through the drain hole.

[0009] Thus, in the rotary separation structure provided in this application embodiment, when the rotary separation assembly rotates, the first sealing member can move relative to the rotary separation assembly under the impact of centrifugal force and the water-air mixture, and open the drain hole. Under the action of centrifugal force, the liquid in the water-air mixture moves circumferentially along the inner wall of the rotary separation assembly and is thrown into the liquid storage chamber through the drain hole, thereby preventing the liquid in the water-air mixture from entering the suction assembly.

[0010] In one possible implementation, the rotational separation structure provided in this application further includes a driving component connected to the rotational separation component to drive the rotational separation component to rotate.

[0011] In this way, the rotary separation component can rotate relative to the sewage tank under the drive of the drive component, thereby separating the water-air mixture into gas and liquid under the action of centrifugal force.

[0012] In one possible implementation, the rotary separation structure provided in this application further includes a support component, which is rotatably mounted on the support component.

[0013] Thus, the rotating separation assembly can be installed inside the sewage tank via a support assembly and can rotate relative to the sewage tank.

[0014] In one possible implementation, the rotary separation structure provided in this application further includes a filter element disposed on a support assembly, the filter element being used to filter the gas in the water-gas mixture separated by the rotary separation assembly.

[0015] In this way, the filter element can filter the gas in the water-gas mixture separated by the rotating separation component, so as to prevent small debris, dust and other particles from entering the suction component with the gas and causing damage to the suction component.

[0016] In one possible implementation, the rotary separation structure provided in this application includes a first sealing member comprising a first elastic part and at least one covering part disposed on the first elastic part, the covering part covering the drain hole, and the first elastic part being connected to the rotary separation assembly through the drain hole.

[0017] The first elastic part is configured to deform under the action of the rotating separation component and the water-air mixture, so that the cover part moves relative to the rotating separation component and opens the drain hole; when the rotating separation component stops rotating, it is reset so that the cover part closes the drain hole again.

[0018] Thus, when the rotary separator rotates, the first elastic part undergoes elastic deformation (e.g., elastic extension) under the action of the rotary separator and the water-air mixture, and the cover moves relative to the rotary separator and opens the drain hole. When the rotary separator stops rotating, the first elastic part resets itself by its own elastic force and drives the cover to close the drain hole again.

[0019] In one possible implementation, the rotational separation structure provided in this application has a covering portion that is a second elastic portion.

[0020] Thus, the cover is an elastic structure that can block the drain hole through its own deformation, thereby increasing the sealing performance of the drain hole.

[0021] In one possible implementation, the rotational separation structure provided in this application has the first elastic part and the covering part integrally formed.

[0022] In this way, the first elastic part and the covering part are integrally molded, resulting in a tighter connection and higher structural strength, thus reducing fatigue damage. Furthermore, the integrally molded structure also reduces production costs.

[0023] In one possible implementation, the rotary separation structure provided in this application has at least one mounting groove on the rotary separation component, a drain hole correspondingly disposed in the mounting groove, and a cover correspondingly disposed in the mounting groove.

[0024] In this way, the cover can be installed on the rotary separation assembly through the mounting groove. The mounting groove can play a certain guiding and limiting role, so that the cover can be aligned with and cover the drain hole under the action of the first elastic part, avoiding misalignment between the cover and the drain hole, and preventing the cover from completely blocking the drain hole, which would cause the liquid in the storage chamber to enter the rotary separation assembly.

[0025] In one possible implementation, the rotary separation structure provided in this application has multiple drainage holes and a cover, with the drainage holes spaced circumferentially around the rotary separation assembly.

[0026] Thus, by setting multiple drainage holes at circumferential intervals on the periphery of the rotary separation component, the discharge path of liquid in the water-gas mixture is increased, thereby improving the gas-liquid separation efficiency of the rotary separation component for the water-gas mixture.

[0027] In one possible implementation, the rotary separation structure provided in this application has at least two covering portions on the first elastic portion, and a portion of the first elastic portion abuts against the sidewall between two adjacent drainage holes.

[0028] Thus, when the rotary separation assembly rotates, the portion of the first elastic part connected to the two covering parts deforms respectively, and the remaining portion of the first elastic part straddles the side wall between two adjacent drainage holes, and is supported by the side wall between the two adjacent drainage holes to prevent the first seal from falling off the rotary separation assembly.

[0029] In one possible implementation, the rotary separation structure provided in this application further includes an operating part in the first seal, which is disposed on the side of the cover portion away from the first elastic portion.

[0030] The operating part is configured to extend outward from the outside of the rotary separation assembly through the drain hole.

[0031] Thus, when installing the first seal, the first seal can be placed inside the rotary separation assembly, and the operating part can be extended out of the rotary separation assembly through the drain hole. By applying force to the operating part, the cover part can be made to pass through the drain hole and enter the mounting groove located on the outside of the rotary separation assembly due to its own elastic deformation.

[0032] In one possible implementation, the rotary separation structure provided in this application has a separation chamber within the rotary separation component, and a drain hole communicates with the separation chamber. The rotary separation component is configured to rotate to separate a water-air mixture within the separation chamber.

[0033] Thus, after the water-air mixture enters the separation chamber, the rotating separation component rotates to separate the water-air mixture within the separation chamber, and the liquid in the water-air mixture can be thrown into the storage chamber of the sewage tank through the drain hole.

[0034] In one possible implementation, the rotary separation structure provided in this application includes a rotary component having a separation chamber, a drain hole disposed on the periphery of the rotary component, and at least one first airflow channel disposed at the end of the rotary component, the first airflow channel communicating with the separation chamber.

[0035] The rotating element is configured to rotate to separate a water-gas mixture within a separation chamber, with the gas in the water-gas mixture flowing out of the separation chamber through a first airflow channel.

[0036] Thus, as the rotating component rotates, the water-air mixture is subjected to centrifugal force within the separation chamber, separating into gas and liquid. The liquid in the water-air mixture moves circumferentially along the inner wall of the separation chamber under the action of centrifugal force and is thrown out of the separation chamber through the drain holes on the circumference of the rotating component, thereby entering the storage chamber of the wastewater tank. The gas in the water-air mixture flows out of the separation chamber through the first airflow channel under the negative pressure generated by the suction assembly.

[0037] In one possible implementation, the rotary separation structure provided in this application further includes a turbulence-inducing element connected to the rotary component and disposed within the separation chamber. The turbulence-inducing element is configured to rotate with the rotary component to guide the water-air mixture to move circumferentially along the separation chamber.

[0038] Thus, when the rotating component rotates, the turbulence-inducing component can rotate with it. After the water-air mixture enters the separation chamber, the turbulence-inducing component can change the flow direction of the water-air mixture to guide the liquid in the water-air mixture to move circumferentially along the inner wall of the separation chamber. As a result, the liquid in the water-air mixture is thrown into the storage chamber of the sewage tank through the drain hole under the action of centrifugal force.

[0039] In one possible implementation, the rotating separation structure provided in this application includes a main body and multiple turbulence baffles, with the main body connected to the rotating component.

[0040] Multiple turbulence-deflecting ribs are arranged at least one layer around the main body in a circumferential interval;

[0041] Alternatively, multiple turbulence baffles are arranged circumferentially around the main body, and the turbulence baffles extend from one end of the main body along the axial direction of the main body to the other end of the main body.

[0042] In this way, the main body can rotate with the rotating component, thereby driving the turbulence baffles to rotate. After the water-air mixture enters the separation chamber, the liquid in the water-air mixture comes into contact with the turbulence baffles and, under the action of centrifugal force, is thrown onto the inner wall of the rotating component by the turbulence baffles. Some of the gas in the water-air mixture flows out of the separation chamber from the gap between two adjacent turbulence baffles under the negative pressure of the suction component.

[0043] In one possible implementation, the rotary separation structure provided in this application has multiple layers of turbulence baffles spaced around the main body in a circumferential manner, with the turbulence baffles of adjacent layers staggered in the axial direction of the main body.

[0044] In this way, the liquid in the water-air mixture can be fully blocked by the staggered baffles, preventing the liquid in the water-air mixture from moving directly along the axial direction of the main body under negative pressure, thus ensuring more thorough gas-liquid separation of the water-air mixture in the separation chamber.

[0045] In one possible implementation, the rotary separation structure provided in this application has an arc-shaped baffle, with both ends of the arc-shaped baffle connected to both ends of the main body.

[0046] Thus, when the arc-shaped baffles rotate, the angular velocities of the baffles are the same, and the radius of the middle part of the baffles (i.e. the arc-shaped protrusion) is larger. Therefore, the centrifugal force of the middle part of the baffles is larger, thereby guiding the liquid in the water-air mixture to be thrown from the middle part of the baffles to the inner wall of the rotating part, avoiding the liquid from splashing everywhere.

[0047] In one possible implementation, the cross-sectional area of ​​the main body of the rotational separation structure provided in this application gradually increases from both ends to the middle.

[0048] This extends the movement path of the water-air mixture on the main body, further improving the water-air separation effect.

[0049] In one possible implementation, the rotary separation structure provided in this application further includes a guide member connected to the rotary member, and the guide member is provided with at least one second airflow channel, which is in communication with the separation chamber.

[0050] The guide is configured to receive a water-air mixture from the sewage tank via a second airflow channel.

[0051] In this way, the guide can receive the water-air mixture from the sewage tank, so that the water-air mixture enters the separation chamber of the rotating component along the second guide airflow channel.

[0052] In one possible implementation, the rotary separation structure provided in this application has a connecting part on the rotating component, a portion of which is located inside the separation cavity, and a first airflow channel is located on the connecting part.

[0053] The turbulence-inducing component is sleeved on the outside of the connecting part, and the guide component is detachably connected to the part of the connecting part located in the separation cavity.

[0054] Thus, during the rotational separation assembly, the turbulence-inducing component can be first inserted into the separation cavity of the rotating component and fitted onto the outside of the connecting part. Then, the guide component can be placed on the rotating component, and the guide component can be fixed to the connecting part inside the separation cavity. The overall structure is simple and easy to install.

[0055] In one possible implementation, the rotary separation structure provided in this application has a first positioning part on the rotating part and a second positioning part on the guide part, with the first positioning part and the second positioning part being inserted into each other.

[0056] In this way, the first positioning part and the second positioning part are inserted into each other to ensure accurate docking of the guide and the rotating part, so as to facilitate subsequent installation and fixing.

[0057] In one possible implementation, the rotary separation structure provided in this application further includes a bearing component, with the connecting portion connected to the inner ring of the bearing component, and the bearing component located outside the separation cavity.

[0058] Thus, by incorporating bearing components, the rotation of rotating parts can be made smoother, preventing jamming.

[0059] In one possible implementation, the rotary separation structure provided in this application has an arc-shaped guide section on the side of the guide member away from the rotating member, for guiding the water-air mixture into the second guide flow channel.

[0060] In this way, the arc-shaped guide section can guide the water-air mixture into the second guide flow channel to reduce turbulence.

[0061] In one possible implementation, the rotational separation structure provided in this application further includes a second seal, which is sleeved on the outside of the guide.

[0062] Thus, the second seal is positioned between the guide and the sewage tank to fill the gap between the solid-liquid mixing chamber and the storage chamber of the sewage tank.

[0063] Secondly, the sewage tank provided in this application includes a tank body and any of the above-mentioned rotating separation structures, wherein the rotating separation structure is disposed within the tank body.

[0064] In one possible implementation, the wastewater tank provided in this application has a solid-liquid mixing chamber and a liquid storage chamber, and a rotating separation structure is disposed in the liquid storage chamber and communicates with the solid-liquid mixing chamber.

[0065] Thirdly, the cleaning equipment provided in this application includes the equipment body and the wastewater tank as described above, with the equipment body connected to the wastewater tank.

[0095] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0096] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0097] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0098] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0099] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0100] In related technologies, cleaning equipment may include a main unit and a wastewater tank connected together, with a suction component installed on the main unit. When the cleaning equipment is working, the negative pressure generated by the suction component can suck debris and wastewater from the ground into the wastewater tank.

[0101] However, some of the sewage in the sewage tank will enter the suction assembly along with the gas, causing damage to the suction assembly.

[0102] In this technology, a water-air separation component is installed inside the wastewater tank. This component has a drain outlet and is connected to a suction component. The water-air separation component separates the water-air mixture into gas and liquid. The liquid flows back into the wastewater tank through the drain outlet, while the gas enters the suction component. However, when the floor scrubber is moved back and forth, the water in the wastewater tank vibrates, causing some wastewater to splash into the water-air separation component through the drain outlet. Alternatively, when the wastewater tank is in a horizontal position, water may flow back into the water-air separation component through the drain outlet. Both of these issues lead to incomplete gas-liquid separation, allowing some liquid to enter the suction component and potentially damage it.

[0103] In view of the above problems, this application provides a rotary separation structure, a wastewater tank, and a cleaning device. The rotary separation structure includes a rotary separation assembly and at least one first seal. The rotary separation assembly is disposed within the wastewater tank of the cleaning device and has at least one drain hole. The first seal is disposed on the rotary separation assembly through the drain hole and covers the drain hole. When the rotary separation assembly rotates, the first seal can move relative to the rotary separation assembly under the impact of centrifugal force and the water-air mixture, thus opening the drain hole. Under the action of centrifugal force, the liquid in the water-air mixture moves circumferentially along the inner wall of the rotary separation assembly and is thrown into the storage chamber through the drain hole, thereby preventing the liquid in the water-air mixture from entering the suction assembly.

[0104] The following describes in detail, with reference to the accompanying drawings, the specific implementation methods of the rotary separation structure, sewage tank, and cleaning equipment provided in the embodiments of this application.

[0105] Reference Figures 3 to 16As shown in the embodiment of this application, the rotary separation structure 10 includes a rotary separation assembly 100 and at least one first seal 200. The rotary separation assembly 100 is disposed within the wastewater tank 20 of a cleaning device. The rotary separation assembly 100 has at least one drain hole 101 and is configured to rotate to separate a water-air mixture. The first seal 200 is disposed on the rotary separation assembly 100 corresponding to the drain hole 101 and covers the drain hole 101. The first seal 200 is configured to move relative to the rotary separation assembly 100 under the action of the rotary separation assembly 100 and the water-air mixture to open the drain hole 101, so that the liquid separated from the water-air mixture by the rotary separation assembly 100 is thrown into the wastewater tank 20 through the drain hole 101.

[0106] It is understood that the rotating separation structure 10 provided in this application embodiment can be installed inside the wastewater tank 20 of a cleaning device, which can be a floor scrubber. The cleaning device has a suction component that is connected to the rotating separation structure 10. When the cleaning device is working, a negative pressure is generated by the suction component to suck debris and wastewater from the surface to be cleaned into the wastewater tank 20.

[0107] Reference Figure 2 As shown, the wastewater tank 20 has a solid-liquid mixing chamber 201 and a storage chamber 202, which are connected by a connecting channel 203. A rotary separation structure 10 is disposed within the storage chamber 202 and is also connected to the connecting channel 203. Thus, under the action of the suction assembly, debris and wastewater are drawn into the solid-liquid mixing chamber 201, while the water-air mixture can enter the rotary separation structure 10 through the connecting channel 203. Under the action of the rotary separation structure 10, the gas and liquid in the water-air mixture are separated; the liquid enters the storage chamber 202, and the gas enters the suction assembly.

[0108] Reference Figures 3 to 5 As shown, the rotary separation structure 10 includes a rotary separation assembly 100 and at least one first sealing member 200. The rotary separation assembly 100 is connected to the connecting channel 203 and the suction assembly, respectively. A drain hole 101 on the rotary separation assembly 100 is connected to the liquid storage chamber 202. The first sealing member 200 is disposed on the rotary separation assembly 100 through the drain hole 101 and correspondingly covers the drain hole 101. (Refer to...) Figure 6As shown, after the water-air mixture enters the cyclone separator assembly, the rotating separator assembly 100 rotates, and the water-air mixture undergoes circumferential motion under the action of centrifugal force, impacting the first seal 200 through the drain hole 101. Thus, under the impact of centrifugal force and the water-air mixture, the first seal 200 moves relative to the rotating separator assembly 100 and opens the drain hole 101. Under the action of centrifugal force, the water-air mixture separates into gas and liquid. The liquid undergoes circumferential motion along the inner wall of the rotating separator assembly 100 and is thrown into the liquid storage chamber 202 through the drain hole 101, while the gas enters the suction assembly under negative pressure. This prevents the liquid in the water-air mixture from entering the suction assembly.

[0109] Reference Figure 6 As shown, the solid arrows indicate the direction of gas flow in the water-air mixture, and the dashed arrows indicate the direction of liquid flow in the water-air mixture.

[0110] Reference Figure 3 and Figure 5 As shown, when the rotary separation assembly 100 stops rotating (i.e., when it is not working), the first seal 200 can block the drain hole 101. In this way, even if the cleaning equipment is moved back and forth, causing the water in the wastewater tank 20 to vibrate, or when the wastewater tank 20 is in a flat position, the liquid in the storage chamber 202 will not enter the rotary separation assembly 100 through the drain hole 101, thereby preventing liquid from entering the suction assembly.

[0111] The first sealing element 200 is disposed on the rotary separation assembly 100 through the drain hole 101. Part of the first sealing element 200 is located inside the rotary separation assembly 100 through the drain hole 101. This facilitates the installation of the first sealing element 200 with the rotary separation assembly 100, improves the stability of the installation of the first sealing element 200, and prevents the first sealing element 200 from falling off the rotary separation assembly 100 due to centrifugal force, thus failing to cover the drain hole 101.

[0112] It is understood that at least one drain hole 101 and at least one first seal 200 are provided, and the number of drain holes 101 and first seals 200 can both be one. Alternatively, there can be multiple drain holes 101 and one first seal 200, with the first seal 200 simultaneously covering multiple drain holes 101. Or, there can be multiple drain holes 101 and multiple first seals 200, with each first seal 200 corresponding to one drain hole 101. This application does not impose excessive limitations on these aspects.

[0113] In summary, the rotary separation structure 10 provided in this application embodiment allows the first sealing member 200 to move relative to the rotary separation assembly 100 under the impact of centrifugal force and the water-air mixture, thus opening the drain hole 101. Under the action of centrifugal force, the liquid in the water-air mixture moves circumferentially along the inner wall of the rotary separation assembly 100 and is thrown into the storage chamber 202 through the drain hole 101, thereby preventing the liquid in the water-air mixture from entering the suction assembly.

[0114] Reference Figures 4 to 6 As shown, in some embodiments, the rotary separation structure 10 provided in this application further includes a driving component 300, which is connected to the rotary separation component 100 to drive the rotary separation component 100 to rotate.

[0115] In this way, the rotating separation component 100 can rotate relative to the sewage tank 20 under the drive of the drive component 300, thereby separating the water-air mixture into gas and liquid under the action of centrifugal force.

[0116] Among them, reference Figure 4 As shown, in one specific embodiment, the drive component 300 can be an electric drive (e.g., a rotary motor), and the rotation separation component 100 is connected to the rotation shaft of the electric drive. The rotation separation component 100 is driven to rotate by electric drive to improve efficiency.

[0117] In another embodiment, the driving component 300 can also be an air guide structure with blades. The air guide structure is positioned in the gas flow path and rotates under the influence of the gas, thereby driving the rotating separation component 100 to rotate. This results in a simpler overall structure and lower cost. This application does not impose excessive limitations on this aspect.

[0118] Reference Figures 3 to 6 As shown, in some embodiments, the rotary separation structure 10 provided in this application further includes a support component 400, and the rotary separation component 100 is rotatably disposed on the support component 400.

[0119] In this way, the rotating separation assembly 100 can be installed inside the sewage tank 20 by the support assembly 400 and can rotate relative to the sewage tank 20.

[0120] Among them, reference Figures 3 to 6As shown, the support assembly 400 includes a support frame 410 and a bracket cover 420. The support frame 410 has a mounting cavity 411, and a portion of the rotating separation assembly 100 is located within the mounting cavity 411 and rotatably connected to the inner wall of the mounting cavity 411. The rotating separation assembly 100 also communicates with the mounting cavity 411. The bracket cover 420 is placed on the support frame 410, and the bracket cover 420 and the rotating separation assembly 100 are located on opposite sides of the support frame 410. The bracket cover 420 can also serve as the cover of the sewage tank 20. The bracket cover 420 is provided with a vent hole 421, which communicates with the mounting cavity 411. In this way, after the gas in the water-air mixture is separated by the rotating separation assembly 100, the gas can enter the mounting cavity 411 and be discharged from the sewage tank 20 through the vent hole 421, entering the suction assembly.

[0121] Furthermore, refer to Figure 5 and Figure 6 As shown, the drive assembly 300 is disposed in the mounting cavity 411 of the support frame 410. The drive assembly 300 is connected to the part of the rotating separation assembly 100 located in the mounting cavity 411. This is to avoid the drive assembly 300 coming into contact with the liquid in the storage cavity 202 of the sewage tank 20, which would damage the drive assembly 300 and affect its rotation.

[0122] Reference Figure 4 As shown, in some embodiments, the rotary separation structure 10 provided in this application further includes a filter element 500, which is disposed on the support assembly 400 and is used to filter the gas in the water-gas mixture separated by the rotary separation assembly 100.

[0123] The filter element 500 is mounted on the upper cover 420 of the bracket and covers the vent 421.

[0124] In this way, the filter element 500 can filter the gas in the water-gas mixture separated by the rotary separation component 100, so as to prevent small debris, dust and other small objects from entering the suction component with the gas and causing damage to the suction component.

[0125] For example, the filter element 500 can be HEPA, filter cotton, filter screen, etc., and the embodiments of this application do not impose too many restrictions on it.

[0126] Reference Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments, the first seal 200 includes a first elastic portion 210 and at least one covering portion 220 disposed on the first elastic portion 210, the covering portion 220 covering the drain hole 101, and the first elastic portion 210 being connected to the rotary separation assembly 100 through the drain hole 101.

[0127] The first elastic part 210 is configured to deform under the action of the rotating separation assembly 100 and the water-air mixture, so that the cover part 220 moves relative to the rotating separation assembly 100 and opens the drain hole 101; when the rotating separation assembly 100 stops rotating, it is reset so that the cover part 220 closes the drain hole 101 again.

[0128] Thus, when the rotary separator 100 rotates, the first elastic part 210 undergoes elastic deformation (e.g., elastic extension) under the action of the rotary separator 100 and the water-air mixture, and the cover part 220 moves relative to the rotary separator 100 and opens the drain hole 101. When the rotary separator 100 stops rotating, the first elastic part 210 resets itself by its own elastic force and drives the cover part 220 to close the drain hole 101 again.

[0129] The first elastic part 210 is connected to the inner wall of the rotary separation assembly 100 via the drainage hole 101 to facilitate the installation of the first seal 200 and the rotary separation assembly 100. It also ensures that when the first elastic part 210 is reset, its elastic force causes the cover part 220 to press against the outer wall of the rotary separation assembly 100, thereby increasing the sealing performance of the cover part 220 against the drainage hole 101.

[0130] For example, the first elastic part 210 can be a spring; or a structure formed of a material with elastic deformation such as silicone or rubber.

[0131] For example, in one embodiment, the cover portion 220 can be made of metal, plastic, or other materials, as long as the shape of the cover portion 220 matches the shape of the drainage hole 101 and can seal the cover portion 220. Of course, a silicone gasket, rubber gasket, or other sealing ring can be fitted onto the cover portion 220 to increase sealing performance. In another embodiment, the cover portion 220 can also be an elastic structure, for example, formed of a material with elastic deformation such as silicone or rubber, to seal the drainage hole 101 through deformation.

[0132] Reference Figure 8 As shown, in some specific embodiments, the covering portion 220 is a second elastic portion.

[0133] Thus, the cover 220 is an elastic structure that can seal the drain hole 101 through its own deformation, thereby increasing the sealing performance of the drain hole 101.

[0134] For example, the second elastic part can be formed of a material with elastic deformation, such as silicone or rubber.

[0135] Reference Figure 8 As shown, in some specific embodiments, the first elastic part 210 and the covering part 220 are integrally formed.

[0136] In this way, the first elastic part 210 and the covering part 220 are integrally formed, resulting in a tighter connection and higher structural strength, thus reducing fatigue damage. Furthermore, the integrally formed structure also reduces production costs.

[0137] Reference Figure 3 , Figure 8 and Figure 9 As shown, in some embodiments, the rotary separation assembly 100 is provided with at least one mounting groove 102, the drain hole 101 is correspondingly provided in the mounting groove 102, and the cover part 220 is correspondingly provided in the mounting groove 102.

[0138] In this way, the cover 220 can be mounted on the rotary separation assembly 100 through the mounting groove 102. The mounting groove 102 can play a certain guiding and limiting role, so that the cover 220 can be aligned with and cover the drain hole 101 under the action of the first elastic part 210, avoiding misalignment between the cover 220 and the drain hole 101, and preventing the cover 220 from completely blocking the drain hole 101, which would cause the liquid in the storage chamber 202 to enter the rotary separation assembly 100.

[0139] The mounting groove 102 can be quadrilateral, circular, elliptical, or oblong, as long as it matches the shape of the cover portion 220. (See reference...) Figure 9 As shown, the shape of the drain hole 101 can be similar to the shape of the mounting groove 102, and the size of the drain hole 101 is smaller than the size of the mounting groove 102, so as to ensure that the cover 220 can completely block the drain hole 101.

[0140] Reference Figure 4 and Figure 9 As shown, in some embodiments, there are multiple drainage holes 101 and multiple cover portions 220, and the drainage holes 101 are arranged circumferentially around the rotating separation assembly 100.

[0141] In this way, by providing multiple drainage holes 101 at circumferential intervals on the periphery of the rotary separation component 100, the discharge path of liquid in the water-gas mixture is increased, thereby improving the gas-liquid separation efficiency of the rotary separation component 100 for the water-gas mixture.

[0142] Among them, reference Figure 4 , Figure 8 and Figure 9 As shown, there are multiple drainage holes 101, cover parts 220 and mounting grooves 102. The drainage holes 101 and the mounting grooves 102 are arranged in a one-to-one correspondence, and the cover parts 220 are arranged in a one-to-one correspondence within the mounting grooves 102.

[0143] Reference Figure 8As shown, in some embodiments, the first elastic portion 210 is provided with at least two covering portions 220, and a portion of the first elastic portion 210 abuts against the sidewall between two adjacent drainage holes 101.

[0144] Two covering portions 220 are respectively disposed in corresponding mounting grooves 102, and a portion of the first elastic portion 210 is located inside the rotary separation assembly 100 and abuts against the inner wall of the rotary separation assembly 100 between two adjacent drainage holes 101.

[0145] In this way, when the rotary separation assembly 100 rotates, the portion of the first elastic part 210 connected to the two covering parts 220 deforms respectively, and the remaining portion of the first elastic part 210 spans the side wall between the two adjacent drainage holes 101, and is supported by the side wall between the two adjacent drainage holes 101 to prevent the first seal 200 from falling off the rotary separation assembly 100.

[0146] Furthermore, this design simplifies the overall structure and facilitates the installation of the first seal 200 on the rotary separation assembly 100. During installation, the first seal 200 can be inserted entirely into the rotary separation assembly 100. Since the cover portion 220 itself is the second elastic portion, the two cover portions 220 can rely on their own elastic deformation to pass through the drain hole 101 and enter the mounting groove 102 located on the outside of the rotary separation assembly 100. Meanwhile, the first elastic portion 210 abuts against the inner wall of the rotary separation assembly 100 between two adjacent drain holes 101, thus completing the overall installation.

[0147] It is understood that the rotary separation structure 10 provided in this application embodiment includes at least one first seal 200, and the first seal 200 is provided with at least two covering portions 220. In some embodiments, refer to Figure 4 and Figure 8 As shown, there are multiple first sealing elements 200, each including a first elastic portion 210 and two covering portions 220, so that each first sealing element 200 can block two drainage holes 101. In some embodiments, there are multiple first sealing elements 200, each including a first elastic portion 210 and two or more covering portions 220, such as 3, 4, or 5, so that each first sealing element 200 can block two or more drainage holes 101, such as 3, 4, or 5. In some embodiments, there is only one first sealing element 200, including a first elastic portion 210 and multiple covering portions 220, so that all drainage holes 101 can be blocked by this first sealing element 200.

[0148] Reference Figure 3 and Figure 8As shown, in some embodiments, the first seal 200 further includes an operation portion 230, which is disposed on the side of the cover portion 220 opposite to the first elastic portion 210.

[0149] The operating part 230 is configured to extend out of the outside of the rotary separation assembly 100 through the drain hole 101.

[0150] In this way, when the first seal 200 is installed, the first seal 200 can be placed inside the rotary separation assembly 100, and the operating part 230 can be extended out of the outside of the rotary separation assembly 100 through the drain hole 101. By applying force to the operating part 230, the covering part 220 can pass through the drain hole 101 by its own elastic deformation and enter the mounting groove 102 located on the outside of the rotary separation assembly 100.

[0151] The size of the operating part 230 is smaller than the size of the drain hole 101. The material of the operating part 230 can be metal, plastic, elastic, etc. This application embodiment does not impose too many restrictions on this.

[0152] Specifically, the operating part 230 is made of elastic material, and the first elastic part 210, the covering part 220 and the operating part 230 are integrally formed.

[0153] Reference Figures 5 to 7 As shown, in some embodiments, the rotary separation assembly 100 has a separation chamber 103, and the drain hole 101 communicates with the separation chamber 103. The rotary separation assembly 100 is configured to rotate to separate a water-air mixture within the separation chamber 103.

[0154] In this way, after the water-air mixture enters the separation chamber 103, the rotating separation component 100 rotates to separate the water-air mixture in the separation chamber 103, and the liquid in the water-air mixture can be thrown into the storage chamber 202 of the sewage tank 20 through the drain hole 101.

[0155] Among them, reference Figure 5 and Figure 6 As shown, the separation chamber 103 is connected to the mounting chamber 411 of the support frame 410. The gas in the water-gas mixture can flow out of the sewage tank 20 in sequence through the separation chamber 103, the mounting chamber 411 of the support frame 410, and the vent 421 of the bracket cover 420, and enter the suction assembly.

[0156] Reference Figures 5 to 7 As shown, in some embodiments, the rotary separation assembly 100 includes a rotary member 110, the rotary member 110 having a separation chamber 103, a drain hole 101 disposed on the periphery of the rotary member 110, and at least one first airflow channel 111 disposed at the end of the rotary member 110, the first airflow channel 111 communicating with the separation chamber 103.

[0157] The rotating element 110 is configured to rotate to separate the water-gas mixture within the separation chamber 103, with the gas in the water-gas mixture flowing out of the separation chamber 103 via the first airflow channel 111.

[0158] Thus, when the rotating component 110 rotates, the water-air mixture is subjected to centrifugal force within the separation chamber 103, separating it into gas and liquid. Under the action of centrifugal force, the liquid in the water-air mixture moves circumferentially along the inner wall of the separation chamber 103 and is thrown out of the separation chamber 103 through the drain hole 101 on the periphery of the rotating component 110, thereby entering the storage chamber 202 of the wastewater tank 20. The gas in the water-air mixture flows out of the separation chamber 103 through the first airflow channel 111 under the negative pressure generated by the suction assembly.

[0159] The first airflow channel 111 is connected to the mounting cavity 411 of the support frame 410, and the gas in the water-gas mixture flows from the separation cavity 103 to the mounting cavity 411 through the first airflow channel 111.

[0160] Reference Figures 5 to 7 As shown, in some embodiments, the rotating separation assembly 100 further includes a baffle 120 connected to the rotating member 110 and disposed within the separation chamber 103. The baffle 120 is configured to rotate with the rotating member 110 to guide the water-air mixture to move circumferentially along the separation chamber 103.

[0161] In this way, when the rotating member 110 rotates, the turbulence-disrupting member 120 can rotate with the rotating member 110. After the water-air mixture enters the separation chamber 103, the turbulence-disrupting member 120 can change the flow direction of the water-air mixture to guide the liquid of the water-air mixture to move circumferentially along the inner wall of the separation chamber 103, so that the liquid in the water-air mixture is thrown into the storage chamber 202 of the sewage tank 20 through the drain hole 101 under the action of centrifugal force.

[0162] Reference Figure 12 and Figure 13 As shown, in some embodiments, the deflector 120 includes a main body 121 and a plurality of deflector ribs 122, the main body 121 being connected to the rotating member 110. The plurality of deflector ribs 122 are arranged at least one layer around the main body 121 in a circumferentially spaced manner.

[0163] Alternatively, multiple turbulence baffles 122 are arranged circumferentially around the main body 121, and the turbulence baffles 122 extend from one end of the main body 121 along the axial direction of the main body 121 to the other end of the main body 121.

[0164] In this way, the main body 121 can rotate with the rotating component 110, thereby driving the turbulence baffle 122 to rotate. After the water-air mixture enters the separation chamber 103, the liquid in the water-air mixture comes into contact with the turbulence baffle 122 and, under the action of centrifugal force, is thrown onto the inner wall of the rotating component 110 by the turbulence baffle 122. Some of the gas in the water-air mixture flows out of the separation chamber 103 from the gap between two adjacent turbulence baffles 122 under the negative pressure of the suction component.

[0165] Reference Figure 12 As shown, multiple turbulence baffles 122 can be arranged in multiple layers around the circumference of the main body 121, which can block the liquid in the water-air mixture to a certain extent and ensure more thorough gas-liquid separation.

[0166] Reference Figure 13 As shown, the turbulence baffle 122 extends from one end of the main body 121 along the axial direction of the main body 121 to the other end of the main body 121, thereby increasing the contact area with the liquid in the water-air mixture. When rotating, the turbulence baffle 122 can generate a strong centrifugal force to separate the gas and liquid in the water-air mixture, and generate a double centrifugal effect with the rotating part 110 to improve the gas-liquid separation effect.

[0167] Reference Figure 12 and Figure 13 As shown, two adjacent turbulence baffles 122 and the main body 121 together form a gas flow channel for gas to pass through.

[0168] Reference Figure 12 As shown, in some embodiments, multiple layers of turbulence baffles 122 are arranged circumferentially around the main body 121, and the turbulence baffles 122 of adjacent layers are staggered in the axial direction of the main body 121.

[0169] In this way, the liquid in the water-air mixture can be fully blocked by the staggered baffles 122, preventing the liquid in the water-air mixture from moving directly along the axial direction of the main body 121 under the action of negative pressure, so as to ensure that the water-air mixture in the separation chamber 103 is separated into gas and liquid more thoroughly.

[0170] Furthermore, refer to Figure 12 As shown, the turbulence baffle 122 extends radially along the main body 121 to increase the contact area with the liquid in the water-air mixture and enhance the guiding effect on the liquid. When the turbulence baffle 122 rotates, it guides the liquid in the water-air mixture to be thrown radially along the main body 121 onto the inner wall of the rotating member 110.

[0171] Reference Figure 13 As shown, in some embodiments, the turbulence baffle 122 is an arc-shaped component, and the two ends of the arc-shaped component are respectively connected to the two ends of the main body 121.

[0172] In this way, when the arc-shaped baffle 122 rotates, the angular velocity of the baffle 122 is the same, and the radius of the middle part of the baffle 122 (i.e. the arc-shaped protrusion) is larger. Therefore, the centrifugal force of the middle part of the baffle 122 is larger, thereby guiding the liquid in the water-air mixture to be thrown from the middle part of the baffle 122 to the inner wall of the rotating part 110, avoiding the liquid from splashing everywhere.

[0173] Reference Figure 13 As shown, in some embodiments, the cross-sectional area of ​​the main body 121 gradually increases from both ends to the middle.

[0174] This extends the movement path of the water-air mixture on the main body 121, further improving the water-air separation effect.

[0175] Specifically, refer to Figure 13 As shown, the main body 121 is lantern-shaped, which, in conjunction with the arc-shaped baffle 122, can generate a strong centrifugal force to separate the liquid in the water-air mixture when rotating.

[0176] Reference Figure 4 , Figure 7 and Figure 14 As shown, in some embodiments, the rotary separation structure 10 provided in this application further includes a guide 130, which is connected to the rotary member 110. The guide 130 is provided with at least one second airflow channel 131, which communicates with the separation chamber 103. The guide 130 is configured to receive a water-air mixture from the sewage tank 20 via the second airflow channel 131.

[0177] In this way, the guide 130 can receive the water-air mixture from the sewage tank 20, so that the water-air mixture enters the separation chamber 103 of the rotating member 110 along the second guide flow channel 131.

[0178] Specifically, refer to Figure 6 As shown, the solid arrows indicate the flow direction of the gas in the water-gas mixture, and the dashed arrows indicate the flow direction of the liquid in the water-gas mixture. After the water-gas mixture enters the connecting channel 203 of the sewage tank 20, it flows sequentially through the second airflow channel 131 of the guide member 130 and the separation chamber 103 of the rotating member 110. The gas and liquid in the water-gas mixture are separated in the separation chamber 103. The liquid is thrown out of the separation chamber 103 through the drain hole 101 and enters the liquid storage chamber 202 of the sewage tank 20. The gas flows along the first airflow channel 111 on the rotating member 110 to the mounting chamber 411 of the support frame 410, and flows out of the sewage tank 20 through the vent hole 421 of the support cover 420, thereby entering the suction assembly.

[0179] Reference Figure 7 , Figures 9 to 11As shown, in some embodiments, the rotating member 110 has a connecting portion 112, a portion of which is located within the separation cavity 103, and a first airflow channel 111 is located on the connecting portion 112. A baffle member 120 is sleeved on the outside of the connecting portion 112, and a guide member 130 is detachably connected to the portion of the connecting portion 112 located within the separation cavity 103.

[0180] In this way, during the rotational separation assembly, the turbulence-dispersing component 120 can be first inserted into the separation cavity 103 of the rotating component 110 and sleeved on the outside of the connecting part 112. Then, the guide component 130 can be placed on the rotating component 110 and fixed to the connecting part 112 inside the separation cavity 103. The overall structure is simple and easy to install.

[0181] Among them, reference Figure 12 and Figure 13 As shown, the main body 121 of the spoiler 120 is provided with a connecting hole 1211, and the main body 121 of the spoiler 120 is sleeved on the connecting part 112 of the rotating member 110 through the connecting hole 1211. The shape of the connecting hole 1211 can be rectangular, elliptical, etc., to prevent the spoiler 120 and the rotating member 110 from rotating relative to each other.

[0182] The guide 130 and the connecting part 112 are detachably connected. For example, the guide 130 has a connecting through hole, and the connecting part 112 has a threaded hole. A bolt passes through the connecting through hole and is threaded into the threaded hole to achieve a detachable connection between the guide 130 and the connecting part 112. Alternatively, the guide 130 has a connecting through hole, and the connecting part 112 has a slot. A fastener passes through the connecting through hole and engages with the slot to achieve a detachable connection between the guide 130 and the connecting part 112.

[0183] Reference Figure 9 and Figure 10 As shown, in some embodiments, the rotating member 110 is provided with a first positioning part 113, and the guide member 130 is provided with a second positioning part 132, and the first positioning part 113 and the second positioning part 132 are correspondingly inserted into each other.

[0184] In this way, by correspondingly inserting the first positioning part 113 and the second positioning part 132, the guide 130 and the rotating part 110 are accurately connected, so as to facilitate subsequent installation and fixing.

[0185] In this configuration, one of the first positioning part 113 and the second positioning part 132 can be a positioning protrusion ring, and the other is a matching positioning ring groove. For example, see... Figure 9 and Figure 14 As shown, the first positioning part 113 is a positioning protrusion ring, and the second positioning part 132 is a positioning ring groove.

[0186] Reference Figure 4 and Figure 7 As shown, in some embodiments, the rotary separation structure 10 provided in this application further includes a bearing member 700, and the connecting portion 112 is connected to the inner ring of the bearing member 700. The bearing member 700 is located outside the separation cavity 103.

[0187] In this way, by setting the bearing component 700, the rotation of the rotating component 110 is made smoother, and jamming is avoided.

[0188] Specifically, refer to Figure 1 As shown, the bearing component 700 is disposed in the mounting cavity 411 of the support frame 410, and the portion of the connecting part 112 extending into the mounting cavity 411 is connected to the inner ring of the bearing component 700.

[0189] Reference Figure 7 , Figure 14 and Figure 16 As shown, in some embodiments, the guide member 130 is provided with an arc-shaped guide portion 133 on the side opposite to the rotating member 110, so as to guide the water-air mixture into the second guide flow channel 131.

[0190] In this way, the arc-shaped guide section 133 can guide the water-air mixture into the second guide flow channel 131 to reduce turbulence.

[0191] Among them, reference Figure 7 and Figure 16 As shown, there are multiple second airflow channels 131, which are spaced apart around the periphery of the arc-shaped guide section 133. The water-air mixture from the connection channel 203 of the sewage tank 20 is diverted into each second airflow channel 131 under the action of the arc-shaped guide section 133.

[0192] Reference Figure 2 , Figure 4 and Figure 7 As shown, in some embodiments, the rotary separation structure 10 provided in this application further includes a second seal 600, which is sleeved on the outside of the guide 130.

[0193] Thus, the second seal 600 is disposed between the guide 130 and the connection channel 203 of the sewage tank 20 to fill the gap between the solid-liquid mixing chamber 201 and the liquid storage chamber 202 of the sewage tank 20.

[0194] For example, the second seal 600 can be made of elastic materials such as silicone gaskets or rubber gaskets, and this application embodiment does not impose too many restrictions on this.

[0195] Reference Figure 2As shown, the sewage tank 20 provided in this application embodiment includes a tank body and any of the above-mentioned rotating separation structures 10, with the rotating separation structure 10 disposed within the tank body.

[0196] In this embodiment, since the sewage tank 20 adopts the rotary separation structure 10 in the above embodiment, it also has the advantages and benefits brought by the rotary separation structure 10, which will not be elaborated here.

[0197] Reference Figure 2 As shown, in some embodiments, the water tank body has a solid-liquid mixing chamber 201 and a liquid storage chamber 202, and the rotating separation structure 10 is disposed in the liquid storage chamber 202 and communicates with the solid-liquid mixing chamber 201.

[0198] The structure of the sewage tank 20 has been described above and will not be repeated here.

[0199] Specifically, the solid-liquid mixing chamber 201 is used to collect solid debris and sewage, and the liquid storage chamber 202 is used to collect the liquid separated by the rotating separation structure 10.
