Description

Technical Field

[0001] This application relates to the field of floor scrubbing machine technology, and more particularly to a water-air separation component, a wastewater tank, and a floor scrubbing machine. Background Technology

[0002] A floor scrubber is a cleaning device that integrates vacuuming, mopping, and wastewater recycling. It is mainly used for cleaning floors such as ceramic tiles, marble, and epoxy flooring.

[0003] In related technologies, the blower of a floor scrubber draws air from the suction port, creating negative pressure, which draws wastewater into the scrubber's wastewater tank through pipes. To achieve water-air separation, a centrifugal separator is installed inside the wastewater tank. During operation, after the wastewater is drawn into the tank, the centrifugal separator generates strong centrifugal force through high-speed rotation, causing water and air of different densities to move along different paths, thus achieving separation.

[0004] However, the aforementioned centrifugal separation device has a relatively complex structure and high cost. Utility Model Content

[0005] This application provides a water-air separation component, a wastewater tank, and a floor scrubbing machine to address the shortcomings of related technologies.

[0006] In a first aspect, this application provides a water-air separation assembly, including a support member and a flow-dispersing member; the support member is used to be disposed inside a sewage tank and has a flow-dispersing channel inside the support member; the flow-dispersing member is disposed inside the flow-dispersing channel and is configured to guide the water-air mixture entering from one end of the flow-dispersing channel to flow around the flow-dispersing member, so as to separate into air and water at the other end of the flow-dispersing channel, and cause the separated air to flow out of the sewage tank through a first flow channel and the separated water to flow into the sewage tank through a second flow channel.

[0007] In this way, by setting up the baffle, the water-air mixture entering from one end of the baffle channel is guided to flow around the baffle, so that the water-air mixture is separated into air and water at the other end of the baffle channel. The separated air flows out of the sewage tank through the first channel, and the separated water flows into the sewage tank through the second channel. Thus, water-air separation can be achieved without relying on the high-speed rotation of the baffle. The overall structure is simple and low in cost.

[0008] In one possible implementation, the water-air separation assembly provided in this application further includes a flow guide; the flow guide is disposed on the support and is configured to guide the water-air mixture to one end of the turbulence channel.

[0009] In this way, the flow state of the water-air mixture before entering the turbulent flow channel is stabilized by the flow guide, which helps the turbulent component to more effectively change the water flow path, thereby promoting the rapid separation of gas and liquid.

[0010] In one possible implementation, the water-air separation assembly provided in this application further includes a seal; the seal is disposed on the drain member and configured to seal the gap between the drain member and the air inlet component of the sewage tank.

[0011] In this way, a physical isolation layer is formed between the drainage component and the air intake component of the sewage tank by the sealing component, which effectively fills the assembly gap between the two, reduces the leakage and seepage of the water-air mixture, and ensures that the water-air mixture can enter the turbulence channel normally.

[0012] In one possible implementation, the water-air separation component provided in this application includes a first support portion with a turbulence channel inside; the first support portion has multiple through holes at the other end near the turbulence channel, and the multiple through holes are all connected to the turbulence channel, with the through holes located at the beginning of the second channel.

[0013] In this way, the separated water is introduced into the second flow channel through the through holes under the action of inertia, and flows into the sewage tank under the action of gravity. At the same time, the design of multiple through holes can increase the drainage area, speed up the efficiency of the separated water being discharged into the sewage tank, and reduce the interference of some separated water on the flow of subsequent water-air mixture caused by some of it remaining in the turbulent flow channel.

[0014] In one possible implementation, the water-air separation assembly provided in this application further includes a second support portion, which includes an abutment section connected to the first support portion to cover the receiving cavity; the abutment section has multiple exhaust ports located at the other end of the turbulence channel; and / or, the exhaust ports are located at the beginning of the first channel.

[0015] In this way, the exhaust ports are set in the area where the separated gas flows through, so that the separated gas enters the first flow channel through these exhaust ports and flows out of the sewage tank smoothly, reducing the impact of gas retention on the flow state of the subsequent water-gas mixture.

[0016] In one possible implementation, the water-air separation assembly provided in this application further includes a guide section in the second support portion; one end of the guide section is wrapped around the periphery of the abutment portion, the other end of the guide section extends toward the inner wall of the sewage tank, and the projection of the guide section toward the periphery of the first support portion covers each through hole; the other end of the guide section is located at the tail end of the second flow channel.

[0017] In this way, the guide section guides the water flowing into the second channel from the through hole, so that the separated water can flow normally from the beginning to the end of the second channel and then into the sewage tank. The sewage tank collects the separated water, achieving a good separation effect.

[0018] In one possible implementation, the water-air separation component provided in this application further includes a third support portion connected to the second support portion, with the third support portion and the first support portion located on opposite sides of the second support portion; a HEPA assembly for placing a wastewater tank is mounted on the third support portion.

[0019] Thus, by setting the third support and the first support on both sides of the second support, the HEPA assembly is integrated on the third support, making the layout of each component more reasonable and improving the space utilization rate inside the sewage tank.

[0020] In one possible implementation, the water-air separation component provided in this application includes a body portion and at least one spiral portion wound around the body portion. Both the body portion and the spiral portion are placed within a turbulence channel, and the spiral portion extends along the axial direction of the body portion. A spiral channel for the water-air mixture to flow around the body portion is formed between the spiral portion and the turbulence channel.

[0021] Thus, the spiral channel constructed by the spiral part and the turbulence channel is used to extend the flow path of the water-air mixture, increase the separation time, and make the water-air mixture form a rotating flow mode as it flows around the main body from one end of the turbulence channel to the other end of the turbulence channel. Centrifugal force is used to make the water migrate to the second channel and get away from the airflow.

[0022] In one possible implementation, the water-air separation component provided in this application has a cylindrical body, the axis of which coincides with the axis of the first support, and a first gap between the cylinder and the wall of the turbulence channel; the first gap is equal along one end of the turbulence channel toward the other end of the turbulence channel.

[0023] Thus, by setting the main body as a cylinder, the cylinder is easy to process and manufacture, and is suitable for mass production; in addition, the smooth surface of the cylinder can reduce the flow resistance when the water-air mixture flows around the cylinder, and avoid the generation of local eddies; the alignment design of the cylinder and the first support improves the assembly consistency, which is conducive to modular production and later maintenance.

[0024] In one possible implementation, the water-air separation component provided in this application has a body that is a frustum, the axis of which coincides with the axis of the first support, and a second gap between the frustum and the wall of the turbulence channel; the second gap decreases sequentially from one end of the turbulence channel toward the other end of the turbulence channel.

[0025] This design allows the first support to be constructed as a cylindrical shell, with the frustum placed inside. This simplifies the structural design of both the first support and the main body, making manufacturing easier. Furthermore, the smooth surface of the frustum reduces flow resistance and prevents the formation of localized eddies when the water-air mixture flows around it. The alignment of the axes of the frustum and the first support improves assembly consistency and facilitates modular production and subsequent maintenance.

[0026] In one possible implementation, the water-air separation assembly provided in this application has a third gap between the side of the spiral portion away from the main body portion and the channel wall of the turbulence channel.

[0027] Thus, the third spacing provides space for the flow and separation of the water-air mixture, allowing the water separated by centrifugal force in the spiral channel to flow smoothly through the through-holes into the second flow channel and into the wastewater tank. Furthermore, the third spacing provides tolerance for errors during the installation and positioning of the baffle components, improving the assembly flexibility of the components.

[0028] In one possible implementation, the third spacing of the water-air separation component provided in this application is equal in the direction from one end of the turbulence channel to the other end of the turbulence channel.

[0029] In this way, when the main body is cylindrical, the cross-sectional area of ​​the spiral channel is equal along the flow direction of the water-air mixture from one end of the turbulent channel to the other, thus forming a uniform rotating flow field in the spiral channel. This is beneficial for improving the stability of the separation process and reducing local eddies or backflow phenomena. When the main body is frustum-shaped, a gradually narrowing spiral channel can be formed between the spiral section and the turbulent channel. That is, along the flow direction of the water-air mixture from one end of the turbulent channel to the other, the cross-sectional area of ​​the spiral channel gradually decreases. This allows the water-air mixture to gradually accelerate during flow and generate a stronger centrifugal force, achieving more efficient water-air separation.

[0030] In one possible implementation, the water-air separation component provided in this application has a third spacing greater than 0 mm and less than or equal to 0.5 mm.

[0031] This ensures the stability of the flow path of the separated water into the sewage tank, reduces the impact of the wider local spiral channel on the rotation intensity of the water-air mixture flowing around the turbulence element, and helps maintain a good centrifugal separation effect.

[0032] In one possible implementation, the water-air separation component provided in this application includes a mounting part and a flow-guiding part arranged sequentially. The mounting part is disposed on a support member, and the flow-guiding part is located at one end of the turbulence channel. The flow-guiding part has multiple flow-guiding ports that communicate with the turbulence channel, and each flow-guiding port is arranged at intervals along the circumference of the flow-guiding part.

[0033] In this way, after the water-air mixture is drawn into the sewage tank, it first passes through the diversion section and enters the turbulence channel through multiple diversion ports, which helps to improve the stability of the water-air mixture entering the turbulence channel and reduce the local pressure difference fluctuations and liquid splashing caused by the concentrated influx of the water-air mixture into the turbulence channel.

[0034] In one possible implementation, the water-air separation component provided in this application has a first connecting part on the diverting member and a second connecting part on the supporting member; the first connecting part is connected to the second connecting part.

[0035] Thus, through the connection and cooperation of the first connecting part and the second connecting part, the guide component is stably installed on the support component, which helps to reduce the vibration and deformation of the guide component during use, so as to maintain the guiding effect of the guide component on the water-air mixture and make the water-air mixture enter the turbulence channel evenly.

[0036] In one possible implementation, the water-air separation component provided in this application has one of the first connecting part and the second connecting part as a first plug-in part, and the other as a first plug-in hole that matches the first plug-in part; the first plug-in part is plugged into the first plug-in hole.

[0037] This makes it easier to assemble and disassemble the drainage components and support components, reducing operational difficulty and facilitating maintenance.

[0038] In one possible implementation, the water-air separation component provided in this application has a third connecting part on the flow guide and a fourth connecting part on the flow turbulence member; the third connecting part is connected to the fourth connecting part.

[0039] Thus, by connecting the diverting component and the supporting component, the diverting component is connected to the fourth connecting component of the turbulence-disrupting component through the third connecting part, so that the three components can be reliably assembled together, which is beneficial to improving the structural stability of the water-air separation component during use.

[0040] In one possible implementation, the water-air separation component provided in this application has one of the third connecting part and the fourth connecting part as a second insertion part, and the other as a second insertion hole that matches the second insertion part; the second insertion part is inserted into the second insertion hole.

[0041] This makes it easier to assemble and disassemble the diversion and deflection components, reducing operational difficulty and facilitating maintenance.

[0042] In one possible implementation, the water-air separation component provided in this application has at least one of the first insertion portion and the second insertion portion as a screw, and at least one of the first insertion hole and the second insertion hole as a threaded hole; the screw is threadedly connected to the corresponding threaded hole.

[0043] In this way, after screwing the screw into the threaded hole, the connection is tightened through the thread engagement, which helps to improve the connection strength. In addition, the threaded connection can meet the needs of repeated disassembly and installation, and facilitates later maintenance and replacement.

[0044] Secondly, this application provides a sewage tank, including a sewage tank body and a water-air separation component disposed on the sewage tank body as described in any of the first aspects.

[0045] Thus, a wastewater tank equipped with any of the aforementioned water-air separation components can achieve water-air separation without relying on a high-speed rotating centrifugal separation device, resulting in a simple overall structure and low cost.

[0046] In one possible implementation, the wastewater tank provided in this application further includes an air intake component, and the wastewater tank body has a wastewater chamber; the support components of the air intake component and the water-air separation component are both disposed in the wastewater chamber, and the guide component of the water-air separation component is connected to the air intake component through a seal; the turbulence channel of the support component is connected to the wastewater chamber.

[0047] In this way, a physical isolation layer is formed between the drainage component and the air intake component through the sealing component, which effectively fills the assembly gap between the two and reduces the leakage of water and air mixture into the sewage chamber due to water and air mixture not entering the turbulence channel for water and air separation.

[0048] Thirdly, this application provides a floor scrubbing machine, including a floor scrubbing machine body and a wastewater tank, as described in any of the second aspects, disposed on the floor scrubbing machine body.

[0049] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that the water-gas separation component provided by this application can solve, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0068] 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.

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.

[0069] 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 of 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.

[0070] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used 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. Therefore, they should not be construed as limitations on this application.

[0071] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific 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 a sequence other than those illustrated or described herein.

[0072] 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 apparatus 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 apparatus.

[0073] A floor scrubber is a cleaning device that integrates vacuuming, mopping, and wastewater recycling. It is mainly used for cleaning floors such as ceramic tiles, marble, and epoxy flooring.

[0074] In related technologies, the blower of a floor scrubber draws air from the suction port, creating negative pressure to draw wastewater into a wastewater tank through pipes. To achieve water-air separation, a centrifugal separator is installed inside the wastewater tank. During operation, after the wastewater is drawn into the tank, the centrifugal separator generates strong centrifugal force through high-speed rotation, causing water and air of different densities to move along different paths, thus achieving separation.

[0075] However, since the working principle of centrifugal separators relies on the centrifugal force generated by high-speed rotation, on the one hand, in order to achieve effective separation, a corresponding high-efficiency motor is required to provide sufficient speed, making the overall structure after assembly quite complex; on the other hand, high-speed rotation places extremely high demands on dynamic balance, and even a small imbalance or manufacturing error may cause the centrifugal separator to vibrate more, increase noise, or even damage the equipment during high-speed rotation. Therefore, high-precision processing equipment and technology are required, which increases manufacturing costs.

[0076] Therefore, the aforementioned centrifugal separation device has a relatively complex structure and high cost.

[0077] In view of this, embodiments of this application provide a water-air separation component, a wastewater tank, and a floor scrubbing machine. The water-air separation component includes a support member and a flow-dispersing member. The support member is disposed within the wastewater tank and has a flow-dispersing channel. The flow-dispersing member is disposed within the flow-dispersing channel and is configured to guide the water-air mixture entering from one end of the flow-dispersing channel to flow around the flow-dispersing member, so as to separate the water-air mixture into air and water at the other end of the flow-dispersing channel. The separated air flows out of the wastewater tank through a first flow channel, and the separated water flows into the wastewater tank through a second flow channel. Thus, by setting the flow-dispersing member to guide the water-air mixture entering from one end of the flow-dispersing channel to flow around the flow-dispersing member, the water-air mixture is separated into air and water at the other end of the flow-dispersing channel. The separated air flows out of the wastewater tank through the first flow channel, and the separated water flows into the wastewater tank through the second flow channel. Therefore, water-air separation can be achieved without relying on the high-speed rotation of the flow-dispersing member. The water-air separation component provided in this application embodiment has a simple overall structure and low cost.

[0078] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0079] Reference Figure 1 As shown, this application embodiment provides a floor scrubbing machine 300, including a floor scrubbing machine body 310 and a wastewater tank 200 disposed on the floor scrubbing machine body 310.

[0080] For example, the floor scrubber body 310 includes a handle assembly 311, a main unit assembly 312, a body assembly 313, and a floor brush assembly 314. The handle assembly 311 is connected to one end of the body assembly 313, and the floor brush assembly 314 is connected to the other end of the body assembly 313. The main unit assembly 312 and the wastewater tank 200 are arranged on one side of the body assembly 313 along the extending direction of the body assembly 313, and the main unit assembly 312 is located above the water tank assembly and connected to the water tank assembly.

[0081] The handle assembly 311 is used for users to hold and provide operation control functions; the main unit assembly 312 is used to provide the power and control functions required for the operation of the whole machine, and the main unit assembly 312 includes a fan (not shown in the figure); the body assembly 313 is a support and connection platform for the overall structure of the floor scrubber 300; and the floor brush assembly 314 is responsible for completing the tasks of floor cleaning and wastewater recycling.

[0082] This layout makes the overall structure of the floor scrubber 300 more slender and streamlined. The body component 313 serves as the overall support, connecting the handle component 311 and the floor brush component 314, making it easier and more effortless for users to operate it upright.

[0083] The main unit 312 and the wastewater tank 200 are distributed vertically along the extension direction of the body assembly 313 on one side of the body assembly 313, reducing the overall space occupied by the cleaning equipment, making the structure more compact and easier for users to hold and operate. Furthermore, the wastewater tank 200 is close to the floor brush assembly 314, shortening the water delivery path and improving the working efficiency of the cleaning equipment.

[0084] The specific structure of the sewage tank 200 will be described below.

[0085] Reference Figures 2 to 6 As shown, this application embodiment provides a sewage tank 200, including a sewage tank body 210 and a water-air separation component 100 disposed on the sewage tank body 210.

[0086] In some examples, the wastewater tank 200 also includes an air intake component 220, and the wastewater tank body 210 has a wastewater chamber 211; the air intake component 220 and the support member 110 of the water-air separation assembly 100 are both disposed in the wastewater chamber 211, and the guide member 150 of the water-air separation assembly 100 is connected to the air intake component 220 through a seal 160; the turbulence channel 1111 of the support member 110 is connected to the wastewater chamber 211.

[0087] For example, such as Figure 3 As shown, the air intake component 220 includes a placement part 221, a one-way valve 222, and a filter element 223. The placement part 221 is connected to the inner peripheral wall of the sewage tank body 210. The one-way valve 222 is disposed on the placement part 221. The filter element 223 is connected to the placement part 221. The flow guide 150 is connected to the valve cover of the one-way valve 222 through the sealing part 160, so that the filter element 223 is sequentially connected to the valve core of the one-way valve 222 and the turbulence channel 1111 through the placement part 221.

[0088] Furthermore, the sewage tank 200 also includes an upper cover assembly 240 and a lower cover assembly 250, which are respectively disposed on both sides of the sewage tank body 210 along the axial direction. The upper cover assembly 240 is connected to the third support part 113 of the support member 110, and the lower cover assembly 250 forms a sewage inlet pipe 251, which is hinged to a sewage inlet cover plate 252.

[0089] Overall, the wastewater chamber 211 is divided into a solid chamber 2111, a water chamber 2112, a water-air flow chamber 2113, and a gas chamber 2114. The filter element 223 connects to the valve core of the one-way valve 222 via the placement part 221 to form the water-air flow chamber 2113, which is connected to the turbulence channel 1111. The gas chamber 2114 connects to the first flow channel 130 of the water-air separation assembly 100, and the water chamber 2112 connects to the second flow channel 140 of the water-air separation assembly 100.

[0090] In practice, the wastewater tank 200 is used on the floor scrubber 300. The water-air-solid mixture, under the suction of the floor scrubber 300's fan, enters the wastewater inlet pipe 251, opening the wastewater inlet cover 252, allowing the wastewater inlet cover 252 to be opened. Figure 4 Rotate to the position shown Figure 5 The position shown connects the inlet pipe 251 and the solid chamber 2111, allowing the water-air mixture to smoothly enter the solid chamber 2111. As the water-air mixture continues to flow in the direction of the arrow shown, the solids in the water-air mixture are filtered by the filter element 223 and stored in the solid chamber 2111. The remaining water-air mixture flows into the water-air flow chamber 2113 along the arrow shown and flows towards the turbulence channel 1111, where water-air separation is completed by the turbulence element 120.

[0091] Furthermore, the separated water along Figure 5 The arrows shown indicate that the gas flows sequentially into the second flow channel 140 and the water cavity 2112, and the separated gas flows along... Figure 5 The arrow shown in the diagram flows out of the sewage tank body 210 after passing through the first flow channel 130 and the gas chamber 2114 in sequence.

[0092] Thus, the sealing element 160 forms a physical isolation layer between the drainage element 150 and the air intake element 220, effectively filling the assembly gap between the two and reducing the leakage of water-air mixture into the water chamber 2112 of the sewage chamber 211 due to water-air separation instead of properly entering the turbulence channel 1111.

[0093] The following is a detailed description of the specific structure of the water-air separation component 100.

[0094] Reference Figures 3 to 8 As shown, the water-air separation assembly 100 provided in this application embodiment includes a support member 110 and a flow-dispersing member 120. The support member 110 is used to be disposed in the sewage tank 200 and has a flow-dispersing channel 1111. The flow-dispersing member 120 is disposed in the flow-dispersing channel 1111 and is configured to guide the water-air mixture entering from one end of the flow-dispersing channel 1111 to flow around the flow-dispersing member 120 so as to separate into air and water at the other end of the flow-dispersing channel 1111. The separated air flows out of the sewage tank 200 through the first flow channel 130 and the separated water flows into the sewage tank 200 through the second flow channel 140.

[0095] Specifically, the support member 110 is used to fix the flow disruptor 120 and form a flow disruptor channel 1111. The flow disruptor channel 1111 is the channel through which the water-air mixture passes when it goes around the flow disruptor 120, and is used to ensure that the water-air separation process proceeds in an orderly manner. The flow disruptor 120 is used to provide a controllable flow path for the water-air mixture. By changing the flow direction of the water-air mixture, the flow disruptor 120 increases the relative velocity difference between water and air, causing the denser water to separate from the air under the action of inertial force, thereby achieving water-air separation.

[0096] The first flow channel 130 is used to discharge the separated gas outside the sewage tank 200, and the second flow channel 140 is used to introduce the separated water into the sewage tank 200 to complete the sewage recycling process.

[0097] In practice, the wastewater tank 200 can be applied to the floor scrubber 300. One end of the turbulence channel 1111 is opposite to the side of the wastewater tank 200 near the suction port of the floor scrubber 300, and the other end of the turbulence channel 1111 is opposite to the side of the wastewater tank 200 near the fan of the floor scrubber 300; the first channel 130 is connected to the fan of the floor scrubber 300; in use, the suction provided by the fan causes the water-air mixture entering the wastewater tank 200 to enter the turbulence channel 1111 from one end, and is separated after being guided by the turbulence element 120.

[0098] In summary, the water-air separation component 100 provided in this application embodiment, through the setting of the baffle 120, guides the water-air mixture entering from one end of the baffle channel 1111 to flow around the baffle 120, so that the water-air mixture is separated into gas and water at the other end of the baffle channel 1111. The separated gas flows out of the sewage tank 200 through the first channel 130, and the separated water flows into the sewage tank 200 through the second channel 140. Thus, water-air separation can be achieved without relying on high-speed rotation, and the overall structure is simple and low-cost.

[0099] Because the water-air mixture is often in a turbulent state and flows irregularly when entering the wastewater tank 200, direct impact on the turbulence-inducing component 120 or the turbulence-inducing channel 1111 can easily cause problems such as local pressure fluctuations and disordered separation paths, thus affecting the separation efficiency. Therefore, referring to... Figure 3 , Figure 6 and Figure 8 As shown, in some examples, the water-air separation assembly 100 also includes a guide 150; the guide 150 is disposed on the support 110 and is configured to guide the water-air mixture to one end of the turbulence channel 1111.

[0100] Thus, the flow state of the water-air mixture before entering the turbulence channel 1111 is stabilized by the flow guide 150, which helps the turbulence guide 120 to more effectively change the water flow path, thereby promoting the rapid separation of gas and liquid.

[0101] In practical implementation, when the wastewater tank 200 is applied to the floor scrubber 300, the optimized inflow state of the guide component 150 reduces water flow impact and local pressure loss, which helps to reduce the suction force required by the blower of the floor scrubber 300, thereby reducing the overall power consumption of the machine. At the same time, the more stable water flow also helps to reduce the noise generated by the floor scrubber 300 during operation, improving the user experience.

[0102] Furthermore, the water-air separation assembly 100 also includes a seal 160; the seal 160 is disposed on the drain member 150 and is configured to seal the gap between the drain member 150 and the air inlet member 220 of the sewage tank 200.

[0103] Thus, the sealing element 160 forms a physical isolation layer between the diversion element 150 and the air intake component 220 of the sewage tank 200, effectively filling the assembly gap between the two, reducing leakage and seepage of the water-air mixture, and ensuring that the water-air mixture can enter the turbulence channel 1111 normally.

[0104] For example, the sealing element 160 can be a rubber ring, silicone gasket, foam sealing strip, etc., and can be set into a ring or strip structure according to actual needs. This application embodiment does not limit this.

[0105] Reference Figure 6 and Figure 9 As shown, in some embodiments, the support member 110 includes a first support portion 111, which has a turbulence channel 1111 inside; the first support portion 111 is provided with a plurality of through holes 1112 at the other end near the turbulence channel 1111, and the plurality of through holes 1112 are all connected to the turbulence channel 1111, and the through holes 1112 are located at the beginning end of the second channel 140.

[0106] Thus, the separated water, under the influence of inertia, is introduced into the second flow channel 140 through the through hole 1112, and flows into the sewage tank 200 under the influence of gravity. At the same time, the design of multiple through holes 1112 can increase the drainage area, accelerate the efficiency of the separated water being discharged into the sewage tank 200, and reduce the interference of some separated water on the flow of subsequent water-air mixture caused by being retained in the turbulent flow channel 1111.

[0107] For example, the specific number and distribution of through holes 1112 can be reasonably set and optimized according to the separation effect of the turbulence element 120 on the water-air mixture and the flow field distribution of water at the outlet end of the turbulence channel 1111 affected by inertia; in addition, the through holes 1112 can be set as rectangular holes, circular holes, etc., and this application embodiment does not limit this.

[0108] Continue to refer to Figure 9 In some examples, the support member 110 further includes a second support portion 112, which includes an abutment section 1121 connected to the first support portion 111 to cover the turbulence channel 1111; the abutment section 1121 has a plurality of exhaust ports 1123 located at the other end of the turbulence channel 1111; and / or, the exhaust ports 1123 are located at the beginning of the first channel 130.

[0109] Thus, by placing the exhaust port 1123 in the area through which the separated gas flows in a concentrated manner, the separated gas enters the first flow channel 130 through these exhaust ports 1123 and flows smoothly out of the sewage tank 200, reducing the impact of gas retention on the flow state of the subsequent water-gas mixture.

[0110] The exhaust port 1123 can be circular, strip-shaped, grid-like, or other structures, and this application embodiment does not limit this.

[0111] Reference Figure 6 and Figure 9In some embodiments, the second support portion 112 further includes a guide section 1122; one end of the guide section 1122 is wrapped around the periphery of the abutment section 1121, one end of the guide section 1122 extends toward the inner wall of the sewage tank 200, and the projection of the guide section 1122 toward the periphery of the first support portion 111 covers each through hole 1112; the other end of the guide section 1122 is located at the tail end of the second flow channel 140.

[0112] Thus, the guide section 1122 guides the water flowing into the second flow channel 140 from the through hole 1112, so that the separated water can flow normally from the beginning to the end of the second flow channel 140 and then into the sewage tank 200. The sewage tank 200 collects the separated water, achieving a good separation effect.

[0113] Among them, such as Figure 6 and Figure 8 As shown, the guide section 1122 is an annular plate-shaped structure that wraps around the periphery of the abutment section 1121.

[0114] Continue to refer to Figure 6 and Figure 9 In a specific example, the support member 110 also includes a third support part 113, which is connected to the second support part 112. The third support part 113 and the first support part 111 are located on both sides of the second support part 112, respectively. The third support part 113 is used to place the HEPA assembly 230 of the sewage tank 200.

[0115] Thus, by setting the third support part 113 and the first support part 111 to be located on both sides of the second support part 112, the HEPA component 230 is integrated on the third support part 110, making the layout between the components more reasonable and improving the space utilization rate inside the sewage tank 200.

[0116] Among them, the HEPA component 230 is an air filtration component used to remove fine particulate matter such as dust, bacteria, and pollen from the separated air. When the wastewater tank 200 is applied to the floor scrubber 300, it can reduce the amount of dust entering the blower, thereby reducing the risk of blower wear. It can also make the air discharged into the environment cleaner, improving user comfort and health and safety.

[0117] For example, the third support 113 can be installed with the HEPA assembly 230 by plug-in or snap-on means, which facilitates the cleaning or replacement of the HEPA assembly 230 later.

[0118] In practice, the first support part 111, the second support part 112, and the third support part 113 can be integrally formed. This ensures that the support member 110 has good structural reliability and helps to improve its service life.

[0119] Reference Figure 8 and Figure 10 In some examples, the turbulence element 120 includes a body portion 121 and at least one spiral portion 122 wound around the body portion 121. Both the body portion 121 and the spiral portion 122 are placed within the turbulence channel 1111. The spiral portion 122 extends along the axial direction of the body portion 121. A spiral channel 1221 for supplying a water-air mixture to flow around the body portion 121 is formed between the spiral portion 122 and the turbulence channel 1111.

[0120] Thus, the spiral channel 1221 constructed by the spiral part 122 and the turbulence channel 1111 is used to extend the flow path of the water-air mixture and increase the separation time. As the water-air mixture flows around the body part 121 from one end of the turbulence channel 1111 to the other end of the turbulence channel 1111, a rotating flow mode is formed. Centrifugal force is used to make the water migrate to the second channel 140 and get away from the airflow.

[0121] The main body 121 serves as the basic structure of the spoiler 120, providing support and connection points for the spiral section 122; the spiral section 122 can be, for example... Figure 10 The single-headed spiral structure shown; the pitch of the spiral part 122 can be designed according to parameters such as the flow rate and velocity of the water-air mixture entering from one end of the turbulence channel 1111, and this application embodiment does not limit this.

[0122] In practice, the main body 121 and the spiral part 122 can be formed by injection molding, 3D printing, or other methods. This results in a relatively mature molding process that can meet the needs of mass production.

[0123] In some examples, the body 121 is a cylinder (not shown in the figure), the axis of the cylinder coincides with the axis of the first support 111, and there is a first gap between the cylinder and the wall of the turbulence channel 1111; the first gap is equal in all directions from one end of the turbulence channel 1111 to the other end of the turbulence channel 1111.

[0124] Thus, by setting the main body 121 as a cylinder, the cylinder is easy to process and manufacture, and is suitable for mass production; in addition, the cylinder surface is smooth, which can reduce the flow resistance and avoid the generation of local eddies when the water-air mixture flows around the cylinder; the alignment design of the cylinder and the first support part 111 improves the assembly consistency, which is beneficial to modular production and later maintenance.

[0125] In specific implementation, there is a first gap between the cylinder and the wall of the turbulence channel 1111; the first gap is equal along one end of the turbulence channel 1111 towards the other end. Therefore, the first support part 111 can be set as a cylindrical shell, and the diameter of the cylindrical shell is larger than the diameter of the cylinder, making the structural design of the first support part 111 simple, easy to process and manufacture, and suitable for mass production.

[0126] Reference Figure 8 and Figure 10 In other examples, the body 121 is a frustum, the axis of which coincides with the axis of the first support 111, and there is a second gap between the frustum and the wall of the turbulence channel 1111; the second gap decreases sequentially from one end of the turbulence channel 1111 toward the other end of the turbulence channel 1111.

[0127] This configuration allows the first support portion 111 to be designed as a cylindrical shell, with the frustum placed inside. This simplifies the structural design of the first support portion 111 and the main body portion 121, making manufacturing easier. Furthermore, the smooth surface of the frustum reduces flow resistance and prevents the generation of local eddies when the water-air mixture flows around it. The alignment of the axes of the frustum and the first support portion 111 improves assembly consistency and facilitates modular production and subsequent maintenance.

[0128] Reference Figure 8 In some embodiments, the side of the spiral portion 122 facing away from the body portion 121 has a third gap with the channel wall of the turbulence channel 1111.

[0129] Thus, the third spacing provides space for the flow and separation of the water-air mixture, allowing the water separated by centrifugal force in the spiral channel 1221 to flow smoothly through the through hole 1112 into the second flow channel 140 and into the wastewater tank 200. Furthermore, the third spacing provides tolerance for errors during the installation and positioning of the baffle 120, improving the assembly flexibility of the components.

[0130] Furthermore, the third spacing is equal in all directions from one end of the turbulence channel 1111 to the other end of the turbulence channel 1111.

[0131] In this way, when the main body 121 is a cylinder, the cross-sectional area of ​​the spiral channel 1221 along the flow direction of the water-air mixture from one end of the turbulence channel 1111 to the other end is equal, thereby forming a uniform rotating flow field in the spiral channel 1221, which is beneficial to improving the stability of the separation process and reducing local eddies or backflow phenomena.

[0132] When the main body 121 is a frustum, a gradually narrowing spiral channel 1221 can be formed between the spiral section 122 and the turbulence channel 1111. That is, along the flow direction of the water-air mixture from one end of the turbulence channel 1111 to the other end, the cross-sectional area of ​​the spiral channel 1221 gradually decreases. In this way, the water-air mixture can be gradually accelerated during the flow process and generate a stronger centrifugal force, achieving more efficient water-air separation.

[0133] In practice, the third spacing is greater than 0 mm and less than or equal to 0.5 mm.

[0134] This configuration ensures the stability of the flow path of the separated water into the sewage tank 200, reduces the impact of the wide local area of ​​the spiral channel 1221 on the rotation intensity of the water-air mixture flowing around the turbulence element 120, and helps maintain a good centrifugal separation effect.

[0135] It is understandable that when the third spacing is 0, that is, the inner wall of the spiral part 122 is in contact with the inner wall of the first support part 111, thus failing to provide space for the separated water to escape from the spiral channel 1221, affecting the water-air separation effect; when the third spacing is greater than 0.5 mm, it will cause the spiral channel 1221 to widen locally, thereby disrupting the rotational flow pattern of the water-air mixture around the turbulence member 120, reducing the rotational intensity of the water-air mixture, and weakening the centrifugal force effect.

[0136] For example, the third spacing can be 0.2 mm, 0.4 mm or 0.5 mm.

[0137] Reference Figure 8 In some embodiments, the drainage member 150 includes a mounting portion 151 and a drainage portion 152 arranged sequentially; the mounting portion 151 is disposed on the support member 110, and the drainage portion 152 is located at one end of the turbulence channel 1111. The drainage portion 152 has a plurality of drainage ports 1521 communicating with the turbulence channel 1111, and each drainage port 1521 is arranged at intervals along the circumference of the drainage portion 152.

[0138] In this way, after the water-air mixture is drawn into the sewage tank 200, it first passes through the diversion section 152 and enters the turbulence channel 1111 through multiple diversion ports 1521, which helps to improve the stability of the water-air mixture entering the turbulence channel 1111 and reduce the local pressure difference fluctuations and liquid splashing caused by the concentrated influx of the water-air mixture into the turbulence channel 1111.

[0139] The mounting part 151 is designed to achieve stable installation and positioning of the flow guide 150 on the support 110. When the mounting part 151 is set on the support 110, it is connected to the first support part 111 of the support 110. As mentioned above, the first support part 111 is a cylindrical shell. Correspondingly, the mounting part 151 can be set as a ring structure that matches the cylindrical shell. The flow guide 152 is a circular plate structure set inside the ring. When the mounting part 151 is set on the first support part 111, the flow guide 152 is located at one end of the turbulence channel 1111.

[0140] Furthermore, by providing multiple drainage ports 1521 on the drainage section 152, for example, the drainage ports 1521 are configured as follows: Figure 6 The six shown make the drainage portions 152 on both sides of any drainage port 1521 have a straight rod-like structure.

[0141] In specific implementation, the mounting part 151 and the first support part 111 can be connected by means of snap-fit, thread, plug-in, etc. The mounting part 151 and the drainage part 152 can be integrally formed, and this application embodiment does not limit this.

[0142] Reference Figure 8 and Figure 9 In some examples, the drainage member 150 has a first connecting portion 1511 and the support member 110 has a second connecting portion 1113; the first connecting portion 1511 is connected to the second connecting portion 1113.

[0143] Thus, through the connection and cooperation of the first connecting part 1511 and the second connecting part 1113, the guide member 150 is stably installed on the support member 110, which helps to reduce the vibration and deformation of the guide member 150 during use, so as to maintain the guiding effect of the guide member 150 on the water-air mixture and make the water-air mixture enter the turbulence channel 1111 evenly.

[0144] The first connecting part 1511 is disposed on the mounting part 151, and the second connecting part 1113 is disposed on the first support part 111.

[0145] For example, the first connecting part 1511 may be a snap-fit ​​structure, a plug-in structure or a threaded structure, and the second connecting part 1113 may be a connecting structure that matches the first connecting part 1511; or, the first connecting part 1511 and the second connecting part 1113 may be bonded and fixed by an adhesive, such as epoxy resin adhesive, or the first connecting part 1511 and the second connecting part 1113 may be made of metal parts and connected by magnetic attraction. In this respect, the embodiments of this application do not limit the scope of the application.

[0146] For example, one of the first connecting portion 1511 and the second connecting portion 1113 is a first plug-in portion, and the other is a first plug-in hole that matches the first plug-in portion; the first plug-in portion is plugged into the first plug-in hole.

[0147] This makes it easier to assemble and disassemble the drainage component 150 and the support component 110, reducing operational difficulty and facilitating maintenance.

[0148] For example, the first connector can be a square plug, and the first socket can be a square hole that matches the square plug; or, the first connector can be a multi-segment stepped plug, and the first socket can be a stepped socket that matches the multi-segment stepped plug. During the insertion process, one of the first connector and the first socket is pushed toward the other, and the two achieve self-locking through interference fit.

[0149] Reference Figure 8 In some embodiments, the diverting member 150 also has a third connecting portion 1522, and the deflector 120 has a fourth connecting portion 1211; the third connecting portion 1522 is connected to the fourth connecting portion 1211.

[0150] Thus, based on the connection between the diverting component 150 and the supporting component 110, the diverting component 150 is connected to the fourth connecting component 1211 of the turbulence-disrupting component 120 through the third connecting part 1522, so that the three are reliably assembled together, which is beneficial to improving the structural stability of the water-air separation component 100 during use.

[0151] The fourth connecting part 1211 is provided on the main body part 121, and the third connecting part 1522 is provided on the area of ​​the draining part 152 opposite to the main body part 121.

[0152] For example, the third connecting part 1522 may be a snap-fit ​​structure, a plug-in structure or a threaded structure, and the fourth connecting part 1211 may be a connecting structure that matches the third connecting part 1522; or, the third connecting part 1522 and the fourth connecting part 1211 may be bonded and fixed by an adhesive, such as epoxy resin adhesive, or the third connecting part 1522 and the fourth connecting part 1211 may be made of metal parts and connected by magnetic attraction. This application does not limit the embodiments in this regard.

[0153] In a specific implementation, one of the third connecting part 1522 and the fourth connecting part 1211 is a second insertion part, and the other is a second insertion hole that matches the second insertion part; the second insertion part is inserted into the second insertion hole.

[0154] This makes it easier to assemble and disassemble the flow guide 150 and the flow spoiler 120, reducing operational difficulty and facilitating maintenance.

[0155] For example, the second connector can be a square plug, and the second connector hole is a square hole that matches the square plug; or, the second connector can be a multi-segment stepped plug, and the second connector hole is a stepped connector hole that matches the multi-segment stepped plug. During the insertion process, one of the second connector and the second connector hole is pushed toward the other, and the two achieve self-locking through interference fit.

[0156] In some examples, at least one of the first and second insertion portions is a screw, and at least one of the first and second insertion holes is a threaded hole; the screw is threadedly connected to the corresponding threaded hole.

[0157] In this way, after screwing the screw into the threaded hole, the connection is tightened through the thread engagement, which helps to improve the connection strength. In addition, the threaded connection can meet the needs of repeated disassembly and installation, and facilitates later maintenance and replacement.

[0158] For example, the fourth connecting part 1211 on the main body 121 is a second insertion hole, and the third connecting part 1522 on the draining part 152 is a second insertion part. The second insertion hole is a threaded hole, and the second insertion part is a screw. The draining part 152 is provided with a receiving groove for accommodating the screw head, and the screw shank is placed outside the receiving groove. The connection can be completed by aligning the screw shank with the threaded hole on the main body 121.

[0159] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
