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, is a type of cleaning machinery suitable for cleaning hard floors while simultaneously sucking up and removing wastewater from the site. It has advantages such as being environmentally friendly, energy-saving, and highly efficient.

[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 assembly along with the gas, causing damage to the suction assembly. 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 assembly along with the gas, causing damage to the suction assembly.

[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 a first through hole and is configured to rotate to separate a water-air mixture.

[0008] A first seal is disposed on the rotary separation assembly and covers the first through hole. The first seal is configured to open the first through 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 first through hole.

[0009] Thus, when the rotary separator rotates, the first seal can open the first through hole on the rotary separator under the impact of centrifugal force and the water-air mixture. Under the action of centrifugal force, the liquid in the water-air mixture moves circumferentially along the inner wall of the rotary separator and is thrown into the storage chamber through the first through hole, thus preventing the liquid in the water-air mixture from entering the suction assembly. When the rotary separator is not rotating, the first seal can block the first through hole to prevent the liquid in the storage chamber of the wastewater tank 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 wastewater tank under the drive of the drive component, thereby separating the gas and liquid in the water-gas mixture.

[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 main body and an elastic part, with the main body disposed on the outside of the rotary separation assembly;

[0017] An elastic part is provided on the main body. The elastic part is configured to move relative to the main body under the action of the rotating separation component and the water-air mixture to open the first through hole.

[0018] Thus, when the rotary separator rotates, it drives the main body and the elastic part to rotate as well. Under the action of centrifugal force and the water-air mixture, the elastic part moves relative to the main body and extends, thereby opening the first through hole. After the rotary separator stops rotating, the elastic part can rely on its own elasticity to cover the first through hole again, thereby closing the first through hole.

[0019] In one possible implementation, the rotary separation structure provided in this application has a first sealing element that is an elastic element, a main body that is sleeved on the outside of the rotary separation assembly, and an elastic element that is a slit provided on the main body, with the slit corresponding to one side of the first through hole.

[0020] The slit is configured to expand under the action of the rotating separation component and the water-air mixture to open the first through hole.

[0021] Thus, both the main body and the elastic part are made of elastic material, with the elastic part being a slit that can expand or close. When the rotary separation assembly rotates, the elastic part (i.e., the slit) expands under the action of centrifugal force and the water-air mixture, forming a flow channel between itself and the first through hole. Liquid in the water-air mixture can then enter the storage chamber through this flow channel. After the rotary separation assembly stops rotating, the elastic part (i.e., the slit) can contract and close using its own elasticity to close the first through hole, thereby preventing liquid in the storage chamber from re-entering the rotary separation assembly.

[0022] In one possible implementation, the rotary separation structure provided in this application includes a first gap portion and at least one second gap portion communicating with the first gap portion. The main body portion surrounded by the first gap portion and the second gap portion forms an elastic blade, and the elastic blade covers the first through hole.

[0023] Thus, the main body portion enclosed by the first and second slits forms an elastic blade. This elastic blade can unfold under the action of centrifugal force and the water-air mixture, thereby opening the first through-hole. When the rotating separation assembly stops rotating, the elastic blade returns to its original position using its own elasticity and covers the first through-hole again, thus closing the first through-hole.

[0024] In one possible implementation, the rotary separation structure provided in this application has a separation chamber within the rotary separation component, a first through hole communicating with the separation chamber, and the rotary separation component is configured to rotate to separate a water-air mixture within the separation chamber.

[0025] 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 first through hole.

[0026] In one possible implementation, the rotary separation structure provided in this application includes a rotary component having a separation cavity and a first through hole disposed on the periphery of the rotary component.

[0027] The rotating element is configured to rotate to separate the water-gas mixture within the separation chamber and to discharge the gas from the water-gas mixture.

[0028] Thus, as the rotating component rotates, the water-air mixture can be separated within the separation chamber. The liquid in the water-air mixture moves circumferentially along the inner wall of the separation chamber under centrifugal force and is thrown out of the separation chamber through the first through-hole on the circumference of the rotating component, thereby entering the storage chamber of the wastewater tank. The gas in the water-air mixture is discharged from the separation chamber under the negative pressure generated by the suction assembly.

[0029] In one possible implementation, the rotary separation structure provided in this application has a guide member on the rotating component, and a gas guiding channel on the guide member. The gas guiding channel is connected to the separation chamber to guide the gas in the water-gas mixture to be discharged from the separation chamber through the gas guiding channel.

[0030] In this way, the gas in the water-air mixture is guided by the guide element and discharged from the separation chamber through the gas guide channel on the guide element, so as to optimize the gas flow rate and reduce turbulence.

[0031] In one possible implementation, the rotary separation structure provided in this application includes a flow guide comprising:

[0032] The main shaft is mounted on the rotating part, and the main shaft portion is located inside the separation chamber.

[0033] Multiple blade sections are circumferentially arranged on the main shaft and connected to the rotating component, forming an air guide channel between two adjacent blade sections.

[0034] In this way, the main shaft can rotate with the rotating parts and drive the blades to rotate, so as to guide the gas in the water-air mixture to pass through the gas guide channel quickly.

[0035] In one possible implementation, the rotary separation structure provided in this application has a first inclined surface on the end face of the blade portion facing the separation chamber, and the first inclined surface is inclined toward the rotating component.

[0036] Thus, a guiding structure is formed by the first inclined surface to guide the water-air mixture into the air guiding channel along the first inclined surface.

[0037] In one possible implementation, the rotary separation structure provided in this application has a second inclined surface on the side of the blade portion, which is used to guide the airflow in the water-air mixture to the air guide channel.

[0038] In this way, the second inclined surface of the blade can act as a guide to further guide the gas in the water-air mixture into the air guide channel along the second inclined surface, thereby reducing turbulence.

[0039] In one possible implementation, the rotary separation structure provided in this application further includes a turbulence-inducing element connected to the rotary component, with a portion of the turbulence-inducing element located within the separation chamber. The turbulence-inducing element is configured to rotate with the rotary component, guide the water-air mixture into the separation chamber, and guide the water-air mixture to move circumferentially along the separation chamber.

[0040] Thus, when the rotating component rotates, the turbulence-inducing component can rotate with it. When the water-air mixture enters the separation chamber through the turbulence-inducing component, the turbulence-inducing component can change the flow direction of the water-air mixture, so as to guide the water-air mixture to move circumferentially along the inner wall of the separation chamber, thereby causing the liquid in the water-air mixture to be thrown into the storage chamber of the sewage tank through the first through hole under the action of centrifugal force.

[0041] In one possible implementation, the rotary separation structure provided in this application includes the following baffle:

[0042] The connecting part is connected to the rotating part;

[0043] The turbulence part is disposed on the connecting part and is located in the separation cavity. The turbulence part has a flow guiding channel, which is connected to the separation cavity and is correspondingly disposed with the first through hole.

[0044] The flow channel is configured to guide the water-air mixture to move circumferentially along the separation chamber.

[0045] Thus, when the water-air mixture enters the guide channel, the rotating component rotates and drives the turbulence-inducing component to rotate through the connecting part, guiding the water-air mixture to perform circumferential motion through the guide channel. This allows the water-air mixture to flow tangentially from the guide channel into the separation chamber, causing it to move circumferentially along the separation chamber. Under the centrifugal force of the rotating component, the gas and liquid in the water-air mixture are separated. The liquid in the water-air mixture is thrown into the liquid storage chamber, while the gas in the water-air mixture flows through the separation chamber to the gas guide channel.

[0046] In one possible implementation, the rotary separation structure provided in this application has a first flow guiding cavity in the turbulence part, and at least two first baffles are provided in the first flow guiding cavity. The turbulence part and the two adjacent first baffles together form a flow guiding channel.

[0047] Thus, the flow channel is formed by the inner wall of the first flow cavity and the first baffle located within the first flow cavity. The water-air mixture enters through the first flow cavity and flows into the flow channel, where it undergoes circumferential movement under the guidance of the flow channel.

[0048] In one possible implementation, the rotary separation structure provided in this application has at least two second baffles on the turbulence section, and the second baffles are located outside the first guide cavity.

[0049] The turbulence section and the two adjacent second baffles together form a flow guide groove, which is set in accordance with the first through hole.

[0050] Thus, the second baffle and the guide groove are located inside the separation chamber and come into contact with the water-air mixture inside the separation chamber. When the turbulence part rotates under the action of the rotating component, it can drive the second baffle and the guide groove to rotate, so as to further guide the water-air mixture to move circumferentially along the separation chamber, so that the gas and liquid in the water-air mixture are separated more thoroughly, and the liquid is prevented from flowing out of the separation chamber through the gas guide channel.

[0051] In one possible implementation, the rotary separation structure provided in this application includes a first through hole and a second through hole that are connected to each other, and the projection of the first through hole toward the turbulence member is located inside the turbulence member.

[0052] The cross-sectional area of ​​the first through hole is smaller than that of the second through hole.

[0053] Thus, the first through hole is correspondingly arranged with the turbulence-disrupting element, and the cross-sectional area of ​​the first through hole is smaller than that of the second through hole, so as to ensure that the liquid in the separation chamber can be discharged from the separation chamber in a timely manner through the second through hole under the action of centrifugal force.

[0054] In one possible implementation, the rotary separation structure provided in this application has an arc-shaped guide portion provided in the first guide cavity, one end of the first baffle is connected to the arc-shaped guide portion, and the other end is connected to the inner wall of the first guide cavity.

[0055] In this way, after the water-air mixture enters the first guide cavity, it can enter the guide channel formed by the first baffle under the action of the arc-shaped guide part, so as to reduce turbulence.

[0056] In one possible implementation, the rotary separation structure provided in this application further includes a guide portion on the connecting portion, the guide portion having a second guide cavity, the second guide cavity being in communication with the first guide cavity;

[0057] The guide section is configured to receive a water-air mixture from the sewage tank via a second guide cavity.

[0058] In this way, the guide section 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 chamber, the first guide chamber and the guide channel.

[0059] In one possible implementation, the rotary separation structure provided in this application further includes a second seal, which is sleeved on the outside of the guide portion.

[0060] Thus, the second seal is positioned between the guide section and the sewage tank to fill the gap between the solid-liquid mixing chamber and the storage chamber of the sewage tank.

[0061] In one possible implementation, the rotary separation structure provided in this application has at least one first insertion part on the rotating member and at least one second insertion part on the deflector member, with the first insertion part and the second insertion part correspondingly inserted into each other.

[0062] Thus, the first and second plug-in parts are plugged into each other to achieve a detachable connection between the rotating part and the aerodynamic part. The structure is simple and convenient for disassembly and maintenance.

[0063] In one possible implementation, the rotary separation structure provided in this application has a first enclosure portion on the outer side of the rotating component, a second enclosure portion on the outer side of the turbulence component, and a first sealing component disposed between the first enclosure portion and the second enclosure portion.

[0064] Thus, the first seal is installed together by the first enclosure and the second enclosure to prevent the first seal from falling off the rotating separation assembly due to centrifugal force.

[0065] In one possible implementation, the rotary separation structure provided in this application has at least one first limiting part on the outer side of the rotating member and at least one second limiting part on the first sealing member, with the first limiting part and the second limiting part correspondingly inserted into each other.

[0066] Thus, by correspondingly inserting the first limiting part and the second limiting part, the rotation of the first sealing member relative to the rotating member is restricted, causing the first sealing member to be unable to open the first through hole.

[0067] 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.

[0068] 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.

[0069] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] However, some of the sewage in the sewage tank will enter the suction assembly along with the gas, causing damage to the suction assembly.

[0104] 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 moves back and forth, the water in the wastewater tank vibrates, causing some wastewater to re-enter the water-air separation component through the drain outlet. Alternatively, when the wastewater tank is in a horizontal position, water may flow back and re-enter 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.

[0105] 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 a first seal. The rotary separation assembly is disposed within the wastewater tank of the cleaning device. The rotary separation assembly has a first through-hole, and the first seal is disposed on the rotary separation assembly and covers the first through-hole. When the rotary separation assembly rotates, the first seal can open the first through-hole under the impact of centrifugal force and the water-air mixture. 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 first through-hole, thus preventing the liquid in the water-air mixture from entering the suction assembly. When the rotary separation assembly is not rotating, the first seal can block the first through-hole to prevent the liquid in the storage chamber of the wastewater tank from entering the suction assembly.

[0106] 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.

[0107] Reference Figures 3 to 15 As shown, the rotary separation structure 10 provided in this application embodiment includes a rotary separation component 100 and a first sealing member 200.

[0108] A rotary separator 100 is installed inside the wastewater tank 20 of a cleaning device. The rotary separator 100 has a first through-hole 101 and is configured to rotate to separate a water-air mixture. A first seal 200 is provided on the rotary separator 100 and covers the first through-hole 101. The first seal 200 is configured to open the first through-hole 101 under the action of the rotary separator 100 and the water-air mixture, so that the water separated by the rotary separator 100 is thrown out through the first through-hole 101.

[0109] 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, the suction component generates suction force to suck debris and wastewater from the surface to be cleaned into the wastewater tank 20.

[0110] 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 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.

[0111] Reference Figure 3 , Figure 4 and Figure 9 As shown, the rotary separation structure 10 includes a rotary separation component 100 and a first sealing element 200. The rotary separation component 100 is connected to the connecting channel 203 and the suction component, respectively. A first through hole 101 on the rotary separation component 100 is connected to the liquid storage chamber 202, and the first sealing element 200 covers the first through hole 101. After the water-air mixture enters the cyclone separation component 100, the rotary separation component 100 rotates, and the water-air mixture moves circumferentially under the action of centrifugal force, impacting the first sealing element 200 through the first through hole 101. Thus, under the impact of centrifugal force and the water-air mixture, the first sealing element 200 opens the first through hole 101. Under the action of centrifugal force, the water-air mixture separates into gas and liquid. The liquid moves circumferentially along the inner wall of the rotary separation component and is thrown into the liquid storage chamber 202 through the first through hole 101, while the gas in the water-air mixture enters the suction component under negative pressure. This prevents the liquid in the water-air mixture from entering the suction component.

[0112] Among them, reference Figure 9 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.

[0113] Reference Figure 3 and Figure 10 As shown, when the rotary separation assembly 100 is not rotating (i.e., not working), the first seal 200 can block the first through 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 first through hole 101, thereby preventing liquid from entering the suction assembly.

[0114] In summary, the rotary separation structure provided in this application embodiment allows the first sealing member 200 to open the first through hole 101 on the rotary separation member 100 under the impact of centrifugal force and the water-air mixture when the rotary separation assembly 100 rotates. 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 liquid storage chamber 202 through the first through hole 101, thus preventing the liquid in the water-air mixture from entering the suction assembly. When the rotary separation assembly 100 is not rotating, the first sealing member 200 can block the first through hole 101 to prevent the liquid in the liquid storage chamber 202 of the sewage tank 20 from entering the suction assembly.

[0115] Reference Figure 3 , Figure 8 and Figure 9 As shown, in some embodiments, the rotation separation structure provided in this application further includes a driving component 300, which is connected to the rotation separation component 100 to drive the rotation separation component 100 to rotate.

[0116] In this way, the rotary separation component 100 can rotate relative to the sewage tank 20 under the drive of the drive component 300, thereby separating the gas and liquid in the water-gas mixture.

[0117] Among them, reference Figure 3 As shown, the drive assembly 300 can be an electric drive (e.g., a rotary motor). The rotation separation assembly 100 is connected to the rotation shaft of the electric drive and is driven to rotate by electric drive to improve efficiency.

[0118] 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.

[0119] Reference Figure 4 , Figure 8 and Figure 9 As shown, in some embodiments, the rotational separation structure provided in this application further includes a support component 400, and the rotational separation component 100 is rotatably disposed on the support component 400.

[0120] 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.

[0121] Among them, reference Figure 4 , Figure 8 and Figure 9 As shown, the support assembly 400 includes a support frame 410 and a bracket cover 420. The support frame 410 has a mounting cavity 411. The rotary separation assembly 100 is disposed on the support frame 410, and a portion of the rotary separation assembly 100 is located within the mounting cavity 411. The bracket cover 420 covers the support frame 410, and the bracket cover 420 and the rotary 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 wastewater tank 20. The bracket cover 420 is provided with a vent hole 421. In this way, after the gas in the water-air mixture is separated by the rotary separation assembly 100, the gas can enter the mounting cavity 411 and be discharged from the wastewater tank 20 through the vent hole 421.

[0122] Furthermore, refer to Figure 8 and Figure 9 As shown, the drive assembly 300 is disposed in the mounting cavity 411 of the support frame 410 to avoid the drive assembly 300 from contacting the liquid in the liquid storage cavity 202, which would damage the drive assembly 300 and affect the rotation of the drive assembly 300.

[0123] Among them, reference Figure 4 and Figure 10 As shown, a bearing 412 is provided on the support frame 410, and the rotating separation assembly 100 is connected to the inner ring of the bearing 412. In this way, the rotating separation assembly 100 can rotate more smoothly relative to the support frame 410 under the drive of the drive assembly 300, so as to avoid jamming.

[0124] Reference Figure 4 , Figure 8 and Figure 9 As shown, in some embodiments, the rotary separation structure 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.

[0125] The filter element 500 is mounted on the upper cover 420 of the bracket and covers the vent 421.

[0126] 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.

[0127] 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.

[0128] Reference Figures 3 to 6 As shown, in some embodiments, the first seal 200 includes a main body 210 and an elastic part 220, with the main body 210 disposed on the outside of the rotary separation assembly 100.

[0129] An elastic part 220 is provided on the main body 210. The elastic part 220 is configured to move relative to the main body 210 under the action of the rotating separation assembly 100 and the water-air mixture to open the first through hole 101.

[0130] When the rotary separation assembly 100 rotates, it drives the main body 210 and the elastic part 220 to rotate as well. Under the action of centrifugal force and the water-air mixture, the elastic part 220 moves and extends relative to the main body 210, thereby opening the first through hole 101. After the rotary separation assembly 100 stops rotating, the elastic part 220 can re-cover the first through hole 101 by its own elasticity, thereby closing the first through hole 101.

[0131] For example, in some embodiments, the main body 210 may be made of metal, hard plastic or other materials, and the main body 210 is fixed on the rotating separation assembly 100. The elastic part 220 may be made of silicone, rubber or other materials with elastic deformation.

[0132] In other embodiments, both the main body 210 and the elastic part 220 can be made of elastic material, and the main body 210 is sleeved on the outside of the rotating separation assembly 100.

[0133] Reference Figure 5 As shown, in some embodiments, the first sealing member 200 is an elastic member, the main body 210 is sleeved on the outside of the rotating separation assembly 100, and the elastic part 220 is a gap provided on the main body 210, which is correspondingly provided on one side of the first through hole 101.

[0134] The slit is configured to expand under the action of the rotating separation component 100 and the water-air mixture to open the first through hole 101.

[0135] The first sealing element 200 is an elastic element, and the main body 210 and the elastic part 220 are both made of elastic material. The main body 210 is sleeved on the outside of the rotating separation assembly 100.

[0136] Thus, both the main body 210 and the elastic part 220 are made of elastic material, and the elastic part 220 is a slit that can be expanded or closed. When the rotating separation assembly 100 rotates, the elastic part 220 (i.e., the slit) expands under the action of centrifugal force and the water-air mixture, forming a flow channel between itself and the first through hole 101, through which the liquid in the water-air mixture can enter the liquid storage chamber 202. After the rotating separation assembly 100 stops rotating, the elastic part 220 (i.e., the slit) can contract and close itself by its own elasticity to close the first through hole 101, thereby preventing the liquid in the liquid storage chamber 202 from re-entering the rotating separation assembly 100.

[0137] The gap is provided on one side of the first through hole 101 to prevent the gap from directly communicating with the first through hole 101 when the rotating separation assembly 100 stops rotating, which would cause the liquid in the liquid storage chamber 202 to directly enter the first through hole 101 through the gap.

[0138] Reference Figure 5 As shown, in some embodiments, the gap includes a first gap portion 221 and at least one second gap portion 222 communicating with the first gap portion 221. The portion of the main body 210 enclosed by the first gap portion 221 and the second gap portion 222 forms an elastic blade 211, which covers the first through hole 101.

[0139] Thus, the portion of the main body 210 enclosed by the first slit 221 and the second slit 222 forms an elastic blade 211. The elastic blade 211 can unfold under the action of centrifugal force and the water-air mixture, thereby opening the first through hole 101. When the rotating separation assembly 100 stops rotating, the elastic blade 211 returns to its original position by its own elastic force and covers the first through hole 101 again, thereby closing the first through hole 101.

[0140] Specifically, refer to Figure 5 As shown, there are two second slits 222, each communicating with the end of the first slit 221. The first slit 221 and the second slit 222 are intersecting each other to form an elastic blade 211 on the main body 210. Preferably, the first slit 221 and the second slit 222 are arranged perpendicularly.

[0141] Reference Figures 8 to 10 As shown, in some embodiments, the rotary separation assembly 100 has a separation chamber 102, and a first through hole 101 communicates with the separation chamber 102. The rotary separation assembly 100 is configured to rotate to separate a water-air mixture within the separation chamber 102.

[0142] In this way, after the water-air mixture enters the separation chamber 102, the rotating separation component 100 rotates to separate the water-air mixture in the separation chamber 102, and the liquid in the water-air mixture can be thrown into the storage chamber 202 of the sewage tank 20 through the first through hole 101.

[0143] Among them, reference Figure 8 As shown, the separation chamber 102 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 102, the mounting chamber 411 of the support frame 410, and the vent 421 of the bracket cover 420, and enter the suction assembly.

[0144] Reference Figures 8 to 12 As shown, in some embodiments, the rotating separation assembly 100 includes a rotating member 110, the rotating member 110 having a separation cavity 102, and a first through hole 101 disposed on the periphery of the rotating member 110.

[0145] The rotating element 110 is configured to rotate to separate the water-gas mixture within the separation chamber 102 and to discharge the gas in the water-gas mixture.

[0146] Thus, when the rotating component 110 rotates, the water-air mixture can be separated within the separation chamber 102. Under the action of centrifugal force, the liquid in the water-air mixture moves circumferentially along the inner wall of the separation chamber 102 and is thrown out of the separation chamber 102 through the first through-hole 101 on the circumference of the rotating component 110, thereby entering the storage chamber 202 of the wastewater tank 20. The gas in the water-air mixture is discharged from the separation chamber 102 under the negative pressure generated by the suction assembly.

[0147] Reference Figure 10 and Figure 12 As shown, in some embodiments, the rotating member 110 has a guide member 112. The rotating member 110 is provided with the guide member 112, and the guide member 112 is provided with a gas guiding channel 111. The gas guiding channel 111 is connected to the separation chamber 102 to guide the gas in the water-gas mixture to be discharged from the separation chamber 102 through the gas guiding channel 111.

[0148] In this way, the gas in the water-air mixture is guided by the guide member 112 and discharged from the separation chamber 102 through the gas guide channel 111 on the guide member 112, so as to optimize the gas flow rate and reduce turbulence.

[0149] Among them, reference Figures 8 to 10 As shown, the gas in the water-gas mixture is discharged from the separation chamber 102 through the gas guide channel 111 on the guide member 112 and then directly enters the mounting chamber 411 of the support frame 410.

[0150] Reference Figures 10 to 12As shown, in some embodiments, the flow guide 112 includes a main shaft portion 1121 and a plurality of blade portions 1122. The main shaft portion 1121 is disposed on the rotating member 110, and a portion of the main shaft portion 1121 is located within the separation chamber 102. The plurality of blade portions 1122 are circumferentially disposed on the main shaft portion 1121 and connected to the rotating member 110, and an air guide channel 111 is formed between two adjacent blade portions 1122.

[0151] In this way, the main shaft 1121 can rotate with the rotating member 110 and drive the blade 1122 to rotate, so as to guide the gas in the water-air mixture to pass quickly through the gas guide channel 111.

[0152] Among them, reference Figure 10 As shown, the main shaft 1121 of the guide member 112 extends into the mounting cavity 411 of the support frame 410 and is connected to the drive assembly 300. A bearing member 412 is provided in the mounting cavity 411, and the rotating member 110 is connected to the inner ring of the bearing member 412. This allows the drive assembly 300 to drive the rotating member 110 to rotate relative to the support frame 410 through the guide member 112.

[0153] Furthermore, refer to Figure 10 As shown, one end of the main shaft 1121 extends into the separation chamber 102, and part of the blade 1122 is located in the separation chamber 102. In this way, the blade 1122 rotates to further guide the water-air mixture in the separation chamber 102 to move circumferentially, so that the gas and liquid in the water-air mixture are separated more thoroughly, and the liquid is prevented from flowing out of the separation chamber 102 through the gas guide channel 111.

[0154] Reference Figure 11 and Figure 12 As shown, in some embodiments, the end face of the blade portion 1122 facing the separation chamber 102 is a first inclined surface 1123, and the first inclined surface 1123 is inclined toward the rotating member 110.

[0155] In this way, a guiding structure is formed by the first inclined surface 1123 to guide the water-air mixture into the air guiding channel 111 along the first inclined surface 1123.

[0156] The blade portion 1122 is an arc-shaped blade, and the inclination angle between the first inclined surface 1123 and the rotating component 110 is greater than 0° and less than 90°. This application embodiment does not impose specific limitations on this.

[0157] Reference Figure 11 and Figure 12 As shown, in some embodiments, the side of the blade portion 1122 is a second inclined surface 1124, which is used to guide the airflow in the water-air mixture to the air guide channel 111.

[0158] In this way, the second inclined surface 1124 of the blade section 1122 can act as a guide to further guide the gas in the water-air mixture into the air guide channel 111 along the second inclined surface 1124, thereby reducing turbulence.

[0159] The second inclined surface 1124 is inclined toward the drive component 300, and the inclination angle between the second inclined surface 1124 and the drive component 300 is greater than 0° and less than 90°. This application embodiment does not impose specific limitations on this.

[0160] Reference Figure 5 , Figure 8 and Figure 10 As shown, in some embodiments, the rotating separation assembly 100 further includes a baffle 120 connected to the rotating assembly 110, and a portion of the baffle 120 is located within the separation chamber 102. The baffle 120 is configured to rotate with the rotating assembly 110, guide the water-air mixture into the separation chamber 102, and guide the water-air mixture to move circumferentially along the separation chamber 102.

[0161] In this way, when the rotating member 110 rotates, the turbulence-disrupting member 120 can rotate with the rotating member 110. When the water-air mixture enters the separation chamber 102 through the turbulence-disrupting member 120, the turbulence-disrupting member 120 can change the flow direction of the water-air mixture to guide the water-air mixture to move circumferentially along the inner wall of the separation chamber 102, so that the liquid in the water-air mixture is thrown into the liquid storage chamber 202 of the sewage tank 20 through the first through hole 101 under the action of centrifugal force.

[0162] Reference Figure 10 and Figure 13 As shown, in some embodiments, the flow-disrupting component 120 includes a connecting portion 121 and a flow-disrupting portion 122. The connecting portion 121 is connected to the rotating component 110, and the flow-disrupting portion 122 is disposed on the connecting portion 121. The flow-disrupting portion 122 is located inside the separation cavity 102 and has a flow-guiding channel 1221 that communicates with the separation cavity 102. The flow-guiding channel 1221 is correspondingly disposed with the first through hole 101.

[0163] The flow channel 1221 is configured to guide the water-air mixture toward the first through hole 101.

[0164] Thus, when the water-air mixture enters the guide channel 1221, the rotating member 110 rotates and drives the turbulence-inducing member 122 to rotate through the connecting part 121, so as to guide the water-air mixture to perform circumferential motion through the guide channel 1221. In this way, the water-air mixture can flow tangentially from the guide channel 1221 into the separation chamber 102, so that the water-air mixture moves circumferentially along the separation chamber 102, and under the action of the centrifugal force of the rotating member 110, the gas and liquid in the water-air mixture are separated. The liquid in the water-air mixture is thrown into the liquid storage chamber 202, while the gas in the water-air mixture flows through the separation chamber 102 to the gas guide channel 111.

[0165] Among them, reference Figure 9 and Figure 10 As shown, the plane of the guide channel 1221 is perpendicular to the flow direction of the water-air mixture, which serves to change the flow direction of the water-air mixture and guide the water-air mixture to move in a circumferential direction.

[0166] Reference Figure 10 and Figure 13 As shown, in some embodiments, the turbulence portion 122 has a first flow guiding cavity 1222, and at least two first baffles 123 are provided in the first flow guiding cavity 1222. The turbulence portion 122 and the two adjacent first baffles 123 together form a flow guiding channel 1221.

[0167] Thus, the flow channel 1221 is formed by the inner wall of the first flow cavity 1222 and the first baffle 123 located within the first flow cavity 1222. The water-air mixture enters through the first flow cavity 1222 and flows into the flow channel 1221, where it undergoes circumferential movement under the guidance of the flow channel 1221.

[0168] Among them, reference Figure 13 As shown, there can be two or more first baffles 123, with multiple first baffles 123 spaced circumferentially to form multiple circumferentially distributed guide channels 1221. Multiple first through holes 101 are circumferentially arranged on the circumferential side of the rotating member 110, and the guide channels 1221 are correspondingly arranged with the first through holes 101. Furthermore, multiple first slits are provided on the elastic portion 220 of the first sealing member 200. Thus, after the water-air mixture enters the first guide cavity 1222, it can be diverted through the multiple guide channels 1221, and then the liquid in the water-air mixture can be discharged into the separation cavity 102 through the multiple first through holes 101, thereby increasing the discharge path of the liquid in the water-air mixture and improving the separation efficiency of gas and liquid in the water-air mixture.

[0169] Furthermore, refer to Figure 13 and Figure 14 As shown, the first baffle 123 is an arc-shaped baffle to guide the water-air mixture more smoothly.

[0170] Reference Figure 13 and Figure 15 As shown, in some embodiments, at least two second baffles 124 are provided on the flow-dispersing portion 122, and the second baffles 124 are located outside the first flow-guiding cavity 1222. The flow-dispersing portion 122 and the two adjacent second baffles 124 together form a flow-guiding groove 1241, and the flow-guiding groove 1241 is correspondingly provided with the first through hole 101.

[0171] Among them, reference Figure 10 and Figure 13 As shown, the second baffle 124 is located outside the first guide cavity 1222 and is positioned close to the guide member 112.

[0172] Thus, the second baffle 124 and the guide groove 1241 are located inside the separation chamber 102 and are in contact with the water-air mixture inside the separation chamber 102. When the turbulence part 122 rotates under the action of the rotating member 110, it can drive the second baffle 124 and the guide groove 1241 to rotate, so as to further guide the water-air mixture to move circumferentially along the separation chamber 102, so that the gas and liquid in the water-air mixture are separated more thoroughly, and the liquid is prevented from flowing out of the separation chamber 102 through the air guide channel 111.

[0173] Among them, reference Figure 15 As shown, there can be two or more second baffles 124, with multiple second baffles 124 arranged circumferentially to form multiple circumferentially distributed guide channels 1241. Furthermore, the second baffles 124 can be arc-shaped baffles to more smoothly guide the water-air mixture.

[0174] Furthermore, refer to Figure 10 and Figure 15 As shown, the second baffle 124 is arranged opposite to the blade portion 1122 of the guide member 112. In this way, the two rotate together to further guide the water-air mixture to move circumferentially along the separation chamber 102, so that the gas and liquid in the water-air mixture are separated more thoroughly.

[0175] Reference Figure 7 and Figure 10 As shown, in some embodiments, the first through hole 101 includes a first through hole portion 1011 and a second through hole portion 1012 that are connected to each other. The projection of the first through hole portion 1011 toward the baffle 120 is located inside the baffle 120, and the cross-sectional area of ​​the first through hole portion 1011 is smaller than the cross-sectional area of ​​the second through hole portion 1012.

[0176] In this way, the first through hole 1011 is correspondingly arranged with the turbulence member 120, and the cross-sectional area of ​​the first through hole 1011 is smaller than the cross-sectional area of ​​the second through hole 1012, so as to ensure that the liquid in the separation chamber 102 can be discharged from the separation chamber 102 in a timely manner through the second through hole 1012 under the action of centrifugal force.

[0177] The first through-hole 1011 is correspondingly arranged with the first baffle 123, and the second through-hole 1012 is correspondingly arranged with the second baffle 124. The water-air mixture in the separation chamber 102 undergoes gas-liquid separation mainly at the position of the second baffle 124. The amount of liquid passing through the first through-hole 1011 is less than the amount of liquid passing through the second through-hole 1012. In this way, the cross-sectional area of ​​the first through-hole 1011 is smaller than the cross-sectional area of ​​the second through-hole 1012, ensuring that the liquid at the position of the second baffle 124 can be discharged from the separation chamber 102 in a timely manner under the action of centrifugal force.

[0178] Reference Figures 8 to 10 As shown, in some embodiments, an arc-shaped guide portion 126 is provided inside the first guide cavity 1222, one end of the first baffle 123 is connected to the arc-shaped guide portion 126, and the other end is connected to the inner wall of the first guide cavity 1222.

[0179] In this way, after the water-air mixture enters the first guide cavity 1222, it can enter the guide channel 1221 formed by the first baffle 123 under the action of the arc-shaped guide part 126, so as to reduce turbulence.

[0180] Among them, reference Figure 13 and Figure 14 As shown, there are two or more first baffles 123, each of which is arranged circumferentially along the arc-shaped guide portion 126, so that the formed guide channels 1221 are arranged circumferentially along the arc-shaped guide portion 126. After the water-air mixture enters the first guide cavity 1222, under the action of the arc-shaped guide portion 126, the water-air mixture is diverted into each guide channel 1221.

[0181] Reference Figure 2 and Figure 5 As shown, in some embodiments, the baffle 120 further includes a guide portion 125 disposed on the connecting portion 121. The guide portion 125 has a second guide cavity 1251 communicating with a first guide cavity 1222. The guide portion 125 is configured to receive a water-air mixture from the wastewater tank 20 via the second guide cavity 1251.

[0182] In this way, the guide section 125 can receive the water-air mixture from the sewage tank 20, so that the water-air mixture enters the separation chamber 102 of the rotating member 110 along the second guide chamber 1251, the first guide chamber 1222 and the guide channel 1221.

[0183] Specifically, refer to Figure 2 and Figure 9As 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 entering the connecting channel 203 of the sewage tank 20, the water-gas mixture flows sequentially through the second guide cavity 1251 of the guide part 125, the first guide cavity 1222 of the turbulence part 122, the guide channel 1221 of the turbulence part 122, and the separation cavity 102 of the rotating part 110. The gas and liquid in the water-gas mixture are separated in the separation cavity 102. The liquid is thrown out of the separation cavity 102 through the first through hole 101 and enters the liquid storage cavity 202 of the sewage tank 20. The gas flows along the air guide channel 111 on the rotating part 110 to the mounting cavity 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.

[0184] Reference Figure 2 , Figure 4 and Figure 10 As shown, in some embodiments, the rotation separation structure provided in this application further includes a second seal 600, which is sleeved on the outside of the guide portion 125.

[0185] Thus, the second seal 600 is disposed between the guide portion 125 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.

[0186] 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.

[0187] Reference Figures 11 to 15 As shown, in some embodiments, the rotating member 110 is provided with at least one first insertion portion 114, and the deflector 120 is provided with at least one second insertion portion 128, with the first insertion portion 114 and the second insertion portion 128 correspondingly inserted.

[0188] In this way, the first plug-in part 114 and the second plug-in part 128 are plugged into each other to realize the detachable connection between the rotating part 110 and the turbulence part 120. The structure is simple and convenient for disassembly and maintenance.

[0189] It is understood that there is at least one first plug-in portion 114 and at least one second plug-in portion 128. The number of the first plug-in portion 114 and the second plug-in portion 128 can be one or more, as long as the first plug-in portion 114 and the second plug-in portion 128 are plugged in correspondingly. This application embodiment does not impose too many restrictions on this.

[0190] For example, either the first insertion portion 114 or the second insertion portion 128 is a snap-fit, and the other is a matching slot. (See reference...) Figure 12 and Figure 15As shown, the first insertion part 114 can be a snap-fit, and the second insertion part 128 can be a matching slot. The first insertion part 114 is disposed on the side of the rotating member 110 near the spoiler member 120, and the second insertion part 128 is disposed on the connecting part 121 of the spoiler member 120.

[0191] Reference Figure 5 As shown, in some embodiments, a first enclosure portion 113 is provided on the outer side of the rotating member 110, a second enclosure portion 127 is provided on the outer side of the deflector 120, and a first sealing member 200 is disposed between the first enclosure portion 113 and the second enclosure portion 127.

[0192] In this way, the first sealing element 200 is installed together by the first enclosure part 113 and the second enclosure part 127 to prevent the first sealing element 200 from falling off the rotating separation assembly 100 due to centrifugal force.

[0193] Specifically, refer to Figure 5 As shown, the main body 210 of the first sealing member 200 is disposed between the first enclosure portion 113 and the second enclosure portion 127, and the main body 210 of the first sealing member 200 is disposed on the main body 210 and covers the first through hole 101.

[0194] Reference Figure 5 As shown, in some embodiments, at least one first limiting part 115 is provided on the outer side of the rotating member 110, and at least one second limiting part 230 is provided on the first sealing member 200, with the first limiting part 115 and the second limiting part 230 correspondingly inserted into each other.

[0195] In this way, by correspondingly inserting the first limiting part 115 and the second limiting part 230, the rotation of the first sealing member 200 relative to the rotating member 110 is restricted, so that the first sealing member 200 cannot open the first through hole 101.

[0196] For example, either the first limiting part 115 or the second limiting part 230 is a limiting post, and the other is a matching limiting groove. (Refer to...) Figure 5 As shown, the first limiting part 115 can be a limiting post, and the second limiting part 230 can be a matching limiting groove. The first limiting part 115 is disposed on the outer side of the rotating member 110, and the second limiting part 230 is disposed on the inner side of the first sealing member 200.

[0197] It is understood that at least one first limiting part 115 and at least one second limiting part 230 are provided.
