Description

Technical Field

[0001] The present application relates to the technical field of cleaning devices, and in particular to a dust cup assembly and cleaning equipment. Background Art

[0002] With the development of science and technology and the improvement of living standards, household cleaning equipment such as vacuum cleaners and floor scrubbers have become increasingly popular and have more and more functions.

[0003] In the related art, a cleaning device may include a main unit and a dust collecting component. The main unit is provided with a suction component, and the negative pressure generated by the suction component is used to collect dust and other impurities on the ground into the dust collecting component.

[0004] However, water on the ground can easily enter the main unit, thereby affecting the performance of the electrical components in the main unit. Summary of the Invention

[0005] The present application provides a dust cup assembly and a cleaning device that can prevent water from entering the host.

[0006] To achieve the above-mentioned object, the present application provides a dust cup assembly, comprising a sleeve, a cyclone assembly, a dust and vapor separation assembly, and a filter element. The side of the sleeve has an air inlet, one end of the sleeve is closed, and the other end of the sleeve forms an air outlet. The cyclone assembly is arranged in the sleeve, and the cyclone assembly and the inner wall of the sleeve form a first cyclone chamber, and the first cyclone chamber is connected to the air inlet.

[0007] The dust and vapor separation component is partially disposed in the cyclone component, and a second cyclone chamber is formed between the dust and vapor separation component and the cyclone component. The second cyclone chamber is communicated with the first cyclone chamber, and the second cyclone chamber is located above the first cyclone chamber.

[0008] The filter cover is arranged on the dust and vapor separation component. The dust and vapor separation component is communicated with the air outlet through the filter component. The dust and vapor separation component rotates relative to the cyclone component.

[0009] The dust cup assembly provided by the present application is provided with a sleeve, a cyclone assembly and a dust-vapor separation assembly. Under the action of the suction force provided by the main unit of the cleaning device, the fluid undergoes preliminary and full cyclonic separation in the first cyclone chamber formed between the inner side wall of the sleeve and the outer side wall of the cyclone assembly, and collects the liquid and particles with larger gravity that are initially cyclonically separated. The dust-vapor separation assembly rotates relative to the sleeve. Under the action of the rotation of the dust-vapor separation assembly, the lighter water vapor, dust and particles that enter the second cyclone chamber above the first cyclone chamber are separated, and the lighter water vapor, dust and particles are collected by the second cyclone chamber. The lighter dust (or smaller dust particles) and gas in the fluid are filtered by the filter element and enter the main unit. In this way, the gas entering the main unit is dry, and the frequency of replacing or cleaning the filter element can be reduced. In this way, the problem of damage to the suction assembly or circuit board and other electrical components in the main unit due to water ingress into the main unit is avoided.

[0010] In one possible implementation, the dust cup assembly provided in the present application, the cyclone assembly includes a first rotating member, the first rotating member is inserted into the sleeve, and a first cyclone chamber is formed between the inner wall of the sleeve and part of the outer wall of the first rotating member.

[0011] In one possible implementation, the dust cup assembly provided by the present application, the dust and steam separation assembly includes a spoiler and a support cylinder, the support cylinder is partially disposed in the first rotating member, the spoiler is disposed on the support cylinder, and the spoiler rotates relative to the support cylinder;

[0012] The spoiler is located within the first rotating member, and a second cyclone chamber is formed between the outer wall of the spoiler and the inner wall of the first rotating member. Thus, when fluid enters the second cyclone chamber, the spoiler rotates to stir the air flow, throwing the fluid away from the center of rotation of the spoiler. Water vapor, dust, and particles in the fluid fall into the lower part of the second cyclone chamber, where they are collected by the second cyclone chamber.

[0013] In one possible implementation, the dust cup assembly provided by the present application, wherein the cyclone assembly further includes a second rotating member, the second rotating member being inserted into the first rotating member, and a third cyclone chamber being formed between an outer side wall of the second rotating member and a portion of an inner side wall of the first rotating member;

[0014] The first cyclone chamber, the third cyclone chamber, and the second cyclone chamber are connected in sequence. The cyclone assembly of the present application forms a two-stage cyclone separation structure through the first rotating member and the second rotating member inserted into the first rotating member. In this way, the cyclone assembly has a better effect in separating fluids.

[0017] The third cyclone chamber is located below the second cyclone chamber, and the second rotating member connects the third cyclone chamber and the second cyclone chamber. The third cyclone chamber and the second cyclone chamber are arranged sequentially along the axis of the sleeve to ensure that the fluid is fully cyclonically separated in the third cyclone chamber, then guided by the second rotating member into the second cyclone chamber for separation and processing by the dust and vapor separation assembly.

The third cyclone chamber is connected to the second cyclone chamber via the second air guide channel and the first air guide channel, respectively. The guide portion is used to guide the fluid within the third cyclone chamber, thereby directing the fluid to the lower end of the rotating body. The fluid enters the lower end of the rotating body through the second air guide channel of the guide portion, and then enters the second cyclone chamber through the first air guide channel of the rotating body. This increases the fluid flow distance and effectively reduces the probability of water intrusion into the main unit.

[0022] The second air guide channel is located within the guide portion, with one end of the second air guide channel facing the guide slope of the adjacent guide portion, and the other end of the second air guide channel located on the side of the guide portion facing away from the first support portion. In this application, by providing guide slopes on the guide portions, the fluid flows along the guide slope on one guide portion and is guided by the guide slope to the second air guide channel of the other guide portion adjacent to the first guide slope.

[0023] In a possible implementation, the dust cup assembly provided by the present application has a guide portion abutting against an inner sidewall of the filter portion to separate the third cyclone chamber into an upper cyclone chamber and a lower cyclone chamber;

[0024] The upper cyclone chamber is located between the lower cyclone chamber and the second cyclone chamber. The upper and lower cyclone chambers are connected by a second air guide channel, and the lower and second cyclone chambers are connected by a first air guide channel. This allows the fluid in the upper cyclone chamber to enter the lower cyclone chamber through the cyclonic action of the second air guide channel, facilitating cyclonic separation of the fluid.

[0064] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0065] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, an indirect connection via an intermediate medium, internal communication between two components, or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0066] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0067] In the description of the present application, “plurality” means two or more than two, unless otherwise specifically and precisely defined.

[0068] The terms "first," "second," "third," "fourth," and the like in the specification and claims of this application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the application described herein can, for example, be implemented in orders other than those illustrated or described herein.

[0069] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0070] In related technologies, a cleaning device may include a main unit and a dust collecting component. The main unit has a suction component, which may be a motor. The main unit and the dust collecting component are connected, and the main unit has an air duct and an air outlet. The motor may generate negative pressure to collect dust and other impurities on the ground through the air duct into the dust collecting component, and the gas filtered by the dust collecting component is discharged from the main unit through the air outlet.

[0071] The dust collection assembly may include a filter and a dust cup. The dust cup has a conical cavity, wherein the dust collection assembly adopts the cyclone separation principle, allowing the dust and air to rotate at high speed in the conical cavity, and using the centrifugal force generated to throw the dust with higher density onto the cavity wall of the dust cup, and then collect it at the bottom of the dust cup under the action of gravity. Dust with lower density is discharged from the dust cup with the air flow, causing secondary pollution. In order to avoid secondary pollution, a filter can be provided, wherein the filter can be a filter mesh, a filter hepa, a filter cotton, etc. The smaller the aperture of the filter, the better the dust interception effect.

[0072] However, in addition to impurities such as dust and particles, there are also liquid stains on the ground. Liquid stains can be water stains, milk or juice, etc. Water stains can be water stains that are poured or accidentally spilled on the ground, or sewage generated when the cleaning equipment is wet mopped. Liquid stains are collectively referred to as sewage below. The above sewage will also enter the dust collection component through the air duct, and enter the main unit through the dust collection component, thereby affecting the performance of the electrical components in the main unit. In other words, sewage can cause damage to electrical components such as the suction component or circuit board in the main unit and make them unable to work normally.

[0073] Based on this, an embodiment of the present application provides a dust cup assembly and a cleaning device. The dust cup assembly is provided with a sleeve, a cyclone assembly, and a dust and vapor separation assembly. Under the action of the suction force provided by the main unit of the cleaning device, the fluid undergoes preliminary and full cyclonic separation in a first cyclone chamber formed between the inner side wall of the sleeve and the outer side wall of the cyclone assembly, and collects the liquid and particles with larger gravity that are initially cyclonically separated. The dust and vapor separation assembly rotates relative to the sleeve. Under the action of the rotation of the dust and vapor separation assembly, the lighter water vapor, dust, and particles that enter the second cyclone chamber above the first cyclone chamber are separated and collected by the second cyclone chamber. The lighter dust (or smaller dust particles) and gas in the fluid are filtered by the filter element and then enter the main unit. In this way, the gas entering the main unit is dry, and the frequency of replacing or cleaning the filter element can be reduced. In this way, the problem of water ingress into the main unit causing damage to the suction assembly or circuit board and other electrical components in the main unit and making them unable to function normally is avoided.

[0074] Figure 1 A schematic structural diagram of a dust cup assembly provided in an embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the internal structure of . It should be noted that, Figure 1 and Figure 2 The schematic diagram of each component in the dust cup assembly is shown. The specific structure of the remaining components in the dust cup assembly is not limited to Figure 1 and Figure 2 of examples.

[0075] The dust cup assembly provided in the embodiments of the present application is applied to a cleaning device. The cleaning device may include a main unit, in which a suction assembly is provided, and the suction assembly is used to provide suction force to the dust cup assembly. The cleaning device may be a household cleaning device such as a vacuum cleaner or a mop. When cleaning a surface to be cleaned (such as the ground), a fluid (a general term for a mixture of impurities such as gas, water stains, dust, and particles on the surface to be cleaned) enters the dust cup assembly through the suction port of the cleaning device.

[0076] See also Figure 1 and Figure 2As shown, in the present application, the dust cup assembly includes a sleeve 100, a cyclone assembly 200, a dust and vapor separation assembly 300 and a filter element 400. The side of the sleeve 100 has an air inlet 110, one end of the sleeve 100 is closed, and the other end of the sleeve 100 forms an air outlet 120. The cyclone assembly 200 is arranged in the sleeve 100, and the cyclone assembly 200 and the inner wall of the sleeve 100 form a first cyclone chamber 130, and the first cyclone chamber 130 is connected to the air inlet 110.

[0077] The dust and vapor separation assembly 300 is partially disposed in the cyclone assembly 200 , and a second cyclone chamber 210 is formed between the dust and vapor separation assembly 300 and the cyclone assembly 200 . The second cyclone chamber 210 is connected to the first cyclone chamber 130 , and the second cyclone chamber 210 is located above the first cyclone chamber 130 .

[0078] The filter 400 is covered on the dust and vapor separation assembly 300. The dust and vapor separation assembly 300 is connected to the air outlet 120 through the filter 400. The dust and vapor separation assembly 300 rotates relative to the cyclone assembly 200. The filter 400 can be a filter cotton or a filter HEPA.

[0079] In the present application, the air inlet 110 located on the side of the sleeve 100 allows the fluid to enter the sleeve 100 tangentially through the side of the sleeve 100. Because the cyclone assembly 200 is provided in the sleeve 100, the fluid entering the sleeve 100 rotates around the first cyclone chamber 130 formed between the inner wall of the sleeve 100 and the outer wall of the cyclone assembly 200. Under the action of centrifugal force, the heavier liquid and particles in the fluid fall into the lower part of the first cyclone chamber 130, and the heavier liquid and particles are collected by the first cyclone chamber 130. The first cyclone chamber 130 can also be called a sedimentation area for large particles and sewage.

[0080] Specifically, the axial length of the sleeve 100 may be greater than or equal to twice or more than twice the diameter of the sleeve 100 .

[0081] In the present application, the second cyclone chamber 210 is located above the first cyclone chamber 130, that is, the second cyclone chamber 210 and the first cyclone chamber 130 are arranged in sequence along the axial direction of the sleeve 100, which is different from the nested arrangement of the second cyclone chamber 210 and the first cyclone chamber 130 in the related art. In the present application, the volume of the first cyclone chamber 130 is larger, so that the fluid can be fully separated in the first cyclone chamber 130.

[0082] Lighter water vapor, dust, and particles in the fluid enter the second cyclone chamber 210 formed between the dust and vapor separation assembly 300 and the cyclone assembly 200. The dust and vapor separation assembly 300 rotates within the second cyclone chamber 210, causing the water vapor, dust, and particles to fall into the lower portion of the second cyclone chamber 210. The second cyclone chamber 210 collects the lighter water vapor, dust, and particles, which can also be called a small particle settling zone. The lighter dust (or smaller dust particles) and gas in the fluid are filtered by the filter element 400, then enter the main unit through the air outlet 120 and are discharged through the main unit.

[0083] The dust cup assembly provided in the embodiment of the present application is provided with a sleeve 100, a cyclone assembly 200, and a dust and vapor separation assembly 300. The cyclone assembly 200 is arranged in the sleeve 100, and the dust and vapor separation assembly 300 is partially located in the cyclone assembly 200. Under the action of the suction force provided by the main body of the cleaning device, the fluid undergoes preliminary and full cyclonic separation in the first cyclone chamber 130 formed between the inner wall of the sleeve 100 and the outer wall of the cyclone assembly 200, and the liquid and particles with relatively high gravity obtained by the preliminary cyclonic separation are collected. The dust and vapor separation assembly 300 rotates relative to the sleeve 100. Under the action of the dust and vapor separation assembly 300's rotation, the lighter water vapor, dust, and particles entering the second cyclone chamber 210 above the first cyclone chamber 130 are separated. The lighter water vapor, dust, and particles are collected by the second cyclone chamber 210. The lighter dust (or smaller dust particles) and gas in the fluid are filtered by the filter element 400 and then enter the main unit. In this way, the gas entering the main unit is dry, and the frequency of replacing or cleaning the filter element 400 can be reduced. This avoids the problem of water ingress into the main unit causing damage to the suction assembly or circuit board and other electrical components within the main unit, making them unable to function normally.

[0084] Next, the structure of the cyclone assembly 200 will be described.

[0085] Figure 3 for Figure 1 Schematic diagram of the structure of the middle cyclone component; Figure 4 for Figure 3 Exploded view of . Figures 1 to 4 As shown, the dust cup assembly provided in the embodiment of the present application, the cyclone assembly 200 includes a first rotating member 220, the first rotating member 220 is inserted into the sleeve 100, and a first cyclone chamber 130 is formed between the inner wall of the sleeve 100 and part of the outer wall of the first rotating member 220.

[0086] The upper portion of the first rotating member 220 and the upper portion of the sleeve 100 (e.g., the end near the air outlet 120) can be sealed by a filter element 400, or the upper portion of the first rotating member 220 and the upper portion of the sleeve 100 can be detachably connected. This allows a closed first cyclone chamber 130 to be formed between the outer wall of the first rotating member 220 and the inner wall of the sleeve 100. Fluid enters the first cyclone chamber 130 through the air inlet 110. Under the action of centrifugal force, heavier liquid (e.g., sewage) and particles in the fluid collide with the inner wall of the sleeve 100 or the outer wall of the first rotating member 220, settle, and fall into the lower portion of the first cyclone chamber 130.

[0087] In a specific implementation, the rotation axis of the first rotating member 220 may coincide with the axis of the sleeve 100 .

[0088] In some embodiments, the cyclone assembly 200 further includes a second rotating member 230 , which is inserted into the first rotating member 220 , and a third cyclone chamber 240 is formed between the outer wall of the second rotating member 230 and a portion of the inner wall of the first rotating member 220 ;

[0089] The first cyclone chamber 130, the third cyclone chamber 240, and the second cyclone chamber 210 are sequentially connected. The cyclone assembly 200 of the present application forms a two-stage cyclone separation structure through the first rotating member 220 and the second rotating member 230 inserted into the first rotating member 220. In this way, the cyclone assembly 200 has a better effect in separating fluids.

[0090] Next, the structures of the first rotating member 220 and the second rotating member 230 will be described.

[0091] Please continue to see Figures 2 to 4 As shown, in the dust cup assembly provided in the embodiment of the present application, the first rotating member 220 includes a first supporting portion 221 and a filtering portion 222 which are coaxially arranged.

[0092] The first support portion 221 is connected to the inner wall of the sleeve 100, and the second rotating member 230 is partially located inside the first support portion 221 and the filter portion 222, and a third cyclone chamber 240 is formed between the outer wall of the second rotating member 230 and the inner wall of the first support portion 221, as well as the inner wall of the filter portion 222. The third cyclone chamber 240 is connected to the first cyclone chamber 130 through the filter portion 222.

[0093] In some embodiments, the filter portion 222 may be a metal filter. The first support portion 221 is sleeved on the metal filter to firmly support the metal filter. The metal filter can also filter the fluid and guide the filtered fluid to the third cyclone chamber 240.

[0094] Figure 5 for Figure 2A magnified view of point A in the middle. Figure 2 and Figure 5 As shown, in another embodiment, the first rotating member 220 also includes a third support portion 224, which is sleeved on the lower portion of the filter portion 222, and supports the filter portion 222 through the third support portion 224. The third support portion 224 is connected to the first support portion 221. For example, the third support portion 224 overlaps the first support portion 221, and the third support portion 224 and the first support portion 221 are sealed at the overlap.

[0095] Please continue to see Figures 2 to 5 As shown, in the present application, the third cyclone chamber 240 is located below the second cyclone chamber 210, and the second rotating member 230 connects the third cyclone chamber 240 and the second cyclone chamber 210. In other words, the third cyclone chamber 240 and the second cyclone chamber 210 are arranged in sequence along the axis of the sleeve 100, so that the fluid is fully cyclonically separated in the third cyclone chamber 240, and then guided by the second rotating member 230 into the second cyclone chamber 210 for separation and processing by the dust and vapor separation assembly 300.

[0096] Figure 6 for Figure 3 Schematic diagram of the internal structure; Figure 7 for Figure 4 A schematic structural diagram of the second rotating member; Figure 8 for Figure 7 A structural diagram from another angle; Figure 9 for Figure 7 The main view; Figure 10 for Figure 9 Cross-sectional view of the middle BB section; Figure 11 for Figure 9 Section view of CC section. Figures 2 to 11 As shown, in the dust cup assembly provided in the embodiment of the present application, the second rotating member 230 includes a rotating member body 231 and at least one guide portion 232 , and a first air guide channel 2311 is provided in the axial direction of the rotating member body 231 .

[0097] The guide portion 232 is disposed on the outer wall of the rotating member body 231 . The guide portion 232 is provided with a second air guiding channel 2321 . The third cyclone chamber 240 and the second cyclone chamber 210 are connected via the second air guiding channel 2321 and the first air guiding channel 2311 in sequence.

[0098] In the present application, the guide portion 232 is used to guide the fluid in the third cyclone chamber 240, thereby directing the fluid to the lower end of the rotating body 231. The fluid enters the lower end of the rotating body 231 through the second air guide channel 2321 of the guide portion 232, and then enters the second cyclone chamber 210 through the first air guide channel 2311 of the rotating body 231. This increases the flow distance of the fluid and effectively reduces the possibility of water intrusion into the main unit.

[0099] In a specific implementation, the rotating member body 231 can be tubular, and the inner side wall of the rotating member body 231 forms a second air guide channel 2321 , and the second air guide channel 2321 is connected and extends from one end of the rotating member body 231 to the other end of the rotating member body 231 .

[0100] In some embodiments, there are at least two guide portions 232 , and the guide portions 232 are sequentially spaced apart in the radial direction of the rotating member body 231 .

[0101] In some embodiments, the guide portion 232 has a guide slope 2322 . The guide slope 2322 is spiral and inclined toward the first support portion 221 .

[0102] The second air guiding channel 2321 is located in the guide portion 232 , with one end of the second air guiding channel 2321 facing the adjacent guide slope 2322 of the guide portion 232 , and the other end of the second air guiding channel 2321 is located on a side of the guide portion 232 away from the first support portion 221 .

[0103] For example, the guide portion 232 can be wedge-shaped, with a wedge angle 2323 of the guide portion 232 facing away from the first support portion 221. In other words, the wedge angle 2323 faces the dust and vapor separation assembly 300. The bottom end 2324 of the guide portion 232 faces the first support portion 221. The guide slope 2322 is located between the wedge angle 2323 and the bottom end 2324. The guide slope 2322 is spirally arranged downward along the outer wall of the rotating member body 231. In other words, the distance between the guide slope 2322 and the first support portion 221 decreases from the wedge angle 2323 to the bottom end 2324.

[0104] In the present application, a guiding slope 2322 is provided on the guiding portion 232 , so that the fluid flows along the guiding slope 2322 on one guiding portion 232 and is guided to the second air guide channel 2321 of another guiding portion 232 adjacent to the guiding slope 2322 through the guiding slope 2322 .

[0105] Among them, for example Figure 5As shown, the bottom end 2324 of the guide portion 232 overlaps the first support portion 221, and the position of the guide portion 232 is limited by the first support portion 221. In addition, the bottom end 2324 and the first support portion 221 are sealed at the overlap, thereby preventing air leakage between the bottom end 2324 and the first support portion 221.

[0106] In the dust cup assembly provided in the embodiment of the present application, the guide portion 232 abuts against the inner wall of the filter portion 222 to separate the third cyclone chamber 240 into an upper cyclone chamber 241 and a lower cyclone chamber 242 .

[0107] The upper cyclone chamber 241 is located between the lower cyclone chamber 242 and the second cyclone chamber 210. The upper cyclone chamber 241 and the lower cyclone chamber 242 are connected via the second air guide channel 2321, and the lower cyclone chamber 242 and the second cyclone chamber 210 are connected via the first air guide channel 2311. In this way, the fluid in the upper cyclone chamber 241 can enter the lower cyclone chamber 242 through the cyclonic action of the second air guide channel 2321.

[0108] The second air guiding channel 2321 can form a first-stage cyclone in the third cyclone chamber 240 .

[0109] The first supporting portion 221 may be tapered, with the larger diameter end of the first supporting portion 221 facing the second rotating member 230 .

[0110] The first support portion 221 may form a second stage cyclone in the third cyclone chamber 240 .

[0111] Figure 12 for Figure 4 Schematic diagram of the structure of the first support part. Figure 2 、 Figure 5 and Figure 12 As shown, in some embodiments, the outer side of the first support portion 221 has a first support ring 2211, and the inner side wall of the sleeve 100 has a second support ring 140. The first support ring 2211 is overlapped on the second support ring 140, and the first support ring 2211 and the second support ring 140 separate the first cyclone chamber 130 into a cyclone section 131 and a collection section 132. The cyclone section 131 is connected to the third cyclone chamber 240.

[0112] An end portion of the first support portion 221 facing away from the filter portion 222 defines a communication hole 2213 , and the collecting section 132 is in communication with the third cyclone chamber 240 through the communication hole 2213 .

[0113] Specifically, such as Figure 5As shown, the first support ring 2211 has a first seal 2212 on the side facing the second support ring 140, and the first support ring 2211 and the second support ring 140 are sealed by the first seal 2212. It is understood that the first seal 2212 can also be provided on the side of the second support ring 140 facing the first support ring 2211. In this way, larger particles of liquid and heavier liquid in the fluid separated by the first cyclone chamber 130 are collected at the bottom of the cyclone section 131.

[0114] The end of the first support portion 221 facing away from the filter portion 222 can also be referred to as the small-diameter end of the first support portion 221. The communication hole 2213 is provided at the small-diameter end of the first support portion 221. Thus, the liquid containing medium particles and the slightly heavier liquid in the fluid separated by the third cyclone chamber 240 are guided by the small-diameter end of the first support portion 221 and collected at the bottom of the collection section 132 through the communication hole 2213.

[0115] Figure 13 for Figure 2 Magnified view of point D in the middle. Figure 2 and Figure 13 As shown, in order to facilitate the support of the dust and vapor separation assembly 300, in some embodiments, the first rotating member 220 also includes a second support portion 223, the second support portion 223 is coaxially arranged with the filter portion 222, and the filter portion 222 is located between the first support portion 221 and the second support portion 223, the second support portion 223 is located above the air inlet 110, and the dust and vapor separation assembly 300 is partially inserted into the second support portion 223, and a second cyclone chamber 210 is formed between the second support portion 223 and the outer wall of the second support portion 223.

[0116] In order to fix the second rotating member 230, in some embodiments, a mounting ring 2312 is provided on the outer wall of the rotating member body 231, and the mounting ring 2312 faces the dust and vapor separation assembly 300; the mounting ring 2312 is located in the second support portion 223, and the mounting ring 2312 is connected to the inner bottom surface of the second support portion 223.

[0117] In practice, the mounting ring 2312 can be detachably connected to the inner bottom surface of the second support portion 223 by overlapping or snapping. For example, the mounting ring 2312 is provided with an annular groove 2313, and the inner bottom surface of the second support portion 223 has a protrusion 2231, which is inserted into the annular groove 2313 to secure the second rotating member 230 to the second support portion 223.

[0118] It is understandable that the annular groove 2313 can be provided on the inner bottom surface of the second support portion 223 , and correspondingly, the protrusion 2231 can be located on the mounting ring 2312 .

[0119] In some embodiments, a second sealing member 2314 may be further provided in the annular groove 2313 to seal the connection between the second rotating member 230 and the second supporting portion 223 .

[0120] To facilitate fixing the second support portion 223 , in some embodiments, the outer portion of the second support portion 223 has a third support ring 2232 , the inner wall of the sleeve 100 has a fourth support ring 150 , and the third support ring 2232 overlaps the fourth support ring 150 .

[0121] The structure of the dust and steam separation assembly 300 is described below.

[0122] Figure 14 for Figure 2 Schematic diagram of the structure of the dust and steam separation component; Figure 15 for Figure 14 Exploded view of . Figure 2 、 Figures 13 and 14 As shown, in the present application, the dust and gas separation assembly 300 includes a spoiler 310 and a support cylinder 320 , the support cylinder 320 is partially disposed in the first rotating member 220 , the spoiler 310 is disposed on the support cylinder 320 , and the spoiler 310 rotates relative to the support cylinder 320 .

[0123] The spoiler 310 is located within the first rotating member 220, and the second cyclone chamber 210 is formed between the outer wall of the spoiler 310 and the inner wall of the first rotating member 220. Thus, when fluid enters the second cyclone chamber 210, the spoiler 310 rotates to agitate the air flow, throwing the fluid away from the center of rotation of the spoiler 310. Water vapor, dust, and particles in the fluid fall into the lower part of the second cyclone chamber 210, where they are collected by the second cyclone chamber 210.

[0124] In a specific implementation, the spoiler 310 can be bowl-shaped, and the side of the spoiler 310 can be set to a grid shape, specifically, an inclined grid, so that the lighter dust (or smaller dust particles) and gas after separation enter the support cylinder 320 through the grid, and then are filtered by the filter element 400. For example, the grid is inclined from the bottom of the bowl to the top of the bowl, and the application does not limit the inclination direction, and can be Figure 14 It can be tilted in the clockwise direction or counterclockwise direction.

[0125] In the present application, the support tube 320 is partially inserted into the second support portion 223, and the outer wall of the support tube 320 is detachably connected to the inner wall of the second support portion 223. In this way, the support tube 320 and the spoiler 310 can be easily removed from the second support portion 223 to dump the light water vapor, dust, and particles in the second cyclone chamber 210.

[0126] In a specific implementation, the support tube 320 and the second support portion 223 can be detachably connected by means of a snap connection or a threaded connection. For example, the outer wall of the support tube 320 can be provided with an external thread, and the inner wall of the second support portion 223 can be provided with an internal thread matching the external thread. The internal and external threads are screwed together to connect and seal the support tube 320 and the second support portion 223.

[0127] In some embodiments, the dust and vapor separation assembly 300 further includes a rotating shaft 330 and an impeller 340 . The impeller 340 is located in the support tube 320 , and the impeller 340 and the spoiler 310 are inserted on the rotating shaft 330 .

[0128] The rotating shaft 330 is rotatably connected to the supporting cylinder 320 so that the impeller 340 and the spoiler 310 rotate coaxially.

[0129] The support cylinder 320 may include a support column 323, a rotating shaft 330 may be inserted into the support column 323, a fan wheel 340 is inserted into and fixedly connected to the rotating shaft 330 located at the upper portion of the support column 323, and a spoiler 310 is inserted into and fixedly connected to the rotating shaft 330 located at the upper portion of the support column 323. At least one bearing 324 may be provided between the support cylinder 320 and the support column 323, so that the fan wheel 340, the spoiler 310, and the rotating shaft 330 can rotate smoothly relative to the support cylinder 320.

[0130] In the present application, the impeller 340 may have multiple spiral blades. The impeller 340 serves as a power component. Under the suction force of the cleaning setting, the gas separated by the spoiler 310 is blown onto the concave surface of the spiral blades of the impeller 340, thereby driving the impeller 340 to rotate, and then driving the spoiler 310 to rotate through the rotating shaft 330.

[0131] In some embodiments, the inner sidewall of the support tube 320 has a third air guide channel 321, which is located between the impeller 340 and the spoiler 310. The third air guide channel 321 can be spiral, and the gas separated by the spoiler 310 is guided through the third air guide channel 321 to smoothly enter the filter element 400 through the impeller 340.

[0132] The dust and vapor separation assembly 300 also includes a water impeller 350, which is inserted into the rotating shaft 330 and located between the impeller 340 and the spoiler 310. The water impeller 350 is provided to guide the fluid on top of the spoiler 310 to the side of the spoiler 310. The water impeller 350 may be provided with a through hole for gas circulation.

[0133] In a specific implementation, the support tube 320 has a mounting groove 322 at the end facing the spoiler 310, and the impeller 340 is positioned within the mounting groove 322. The water wheel 350 is partially embedded within the spoiler 310, sealing the gap between the water wheel 350 and the spoiler 310; the water wheel 350 is fixedly connected to the spoiler 310. In this way, the water wheel 350 forms a labyrinth seal around the edge of the spoiler 310, preventing fluid from entering the support tube 320 from the top of the spoiler 310.

[0134] In some embodiments, the dust and vapor separation assembly 300 further includes a cover 360 , which is inserted into the support tube 320 , and the impeller 340 is located between the cover 360 and the spoiler 310 .

[0135] The cover 360 may be provided with a through hole for gas circulation. One of the cover 360 and the support tube 320 may be provided with a slot, and the other may be provided with an insert block, which is inserted into the slot to connect the cover 360 and the support tube 320.

[0136] To facilitate installation of the filter element 400 , in some embodiments, the filter element 400 is partially inserted into the support cylinder 320 , and the filter element 400 abuts against the inner sidewall of the first rotating element 220 .

[0137] An embodiment of the present application also provides a cleaning device, comprising a device body and a dust cup assembly provided by any of the above embodiments, wherein the dust cup assembly is connected to the device body.

[0138] Among them, the structure and working principle of the dust cup assembly are described in detail in the above embodiments and will not be repeated here.

[0139] The device body may include a floor brush structure and a main body, and the dust cup assembly may be arranged on one of the floor brush structure and the dust cup assembly.

[0140] The cleaning device provided in the embodiment of the present application is provided with a dust cup assembly, which is provided with a sleeve 100, a cyclone assembly 200, and a dust and vapor separation assembly 300. The cyclone assembly 200 is arranged in the sleeve 100, and the dust and vapor separation assembly 300 is partially located in the cyclone assembly 200. Under the action of the suction force provided by the main body of the cleaning device, the fluid undergoes preliminary and full cyclonic separation in the first cyclone chamber 130 formed between the inner wall of the sleeve 100 and the outer wall of the cyclone assembly 200, and the liquid and particles with relatively high gravity obtained by the preliminary cyclonic separation are collected. The dust and vapor separation assembly 300 rotates relative to the sleeve 100. Under the action of the dust and vapor separation assembly 300's rotation, the lighter water vapor, dust, and particles entering the second cyclone chamber 210 above the first cyclone chamber 130 are separated. The lighter water vapor, dust, and particles are collected by the second cyclone chamber 210. The lighter dust (or smaller dust particles) and gas in the fluid are filtered by the filter element 400 and then enter the main unit. In this way, the gas entering the main unit is dry, and the frequency of replacing or cleaning the filter element 400 can be reduced. This avoids the problem of water ingress into the main unit causing damage to the suction assembly or circuit board and other electrical components within the main unit, making them unable to function normally.

[0141] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
