Description

Technical Field

[0001] The present application relates to the technical field of cleaning appliances, and in particular to a dust cup structure and a cleaning device. 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, the cleaning device may include a main unit and a dust collecting component. The main unit has a suction component. The negative pressure generated by the suction component can collect dust and other impurities on the ground into the dust collecting component. In order to prevent water on the ground from easily entering the main unit, the dust collecting component may include a separation unit. The separation unit includes a water-blocking wind wheel. The water-blocking wind wheel can generate centrifugal force by its own rotation to separate liquid and gas in the fluid.

[0004] However, there is a gap between the water-blocking wind wheel and the corresponding fixing parts. Under the negative pressure of the main engine, the liquid on the outside of the water-blocking wind wheel can easily enter the inside of the water-blocking wind wheel through the gap, which can easily cause water to enter the main engine. Utility Model Content

[0005] Based on this, the present application provides a dust cup structure and a cleaning device, wherein the dust cup structure improves the waterproof performance of the device host.

[0006] In a first aspect, the present application provides a dust cup structure, including a dust cup, a cyclone separation assembly and a water vapor separation assembly, the dust cup having an air inlet and an air outlet, the cyclone separation assembly being arranged in the dust cup, the cyclone separation assembly having a first cyclone chamber and a first exhaust chamber, the first cyclone chamber and the first exhaust chamber being sequentially connected between the air inlet and the air outlet;

[0007] The water-gas separation component comprises a water-gas separation element and a driving unit, wherein the water-gas separation element is located in the first cyclone chamber, and the driving unit is connected to the water-gas separation element to drive the water-gas separation element to rotate;

[0008] The end of the water vapor separation element facing the air outlet has a first end face, the end of the first exhaust chamber away from the air outlet has a first bottom wall, the end of the first cyclone chamber facing the air outlet has a second bottom wall, a first gap is formed between the first end face and the first bottom wall, and a second gap is formed between the first end face and the second bottom wall.

[0009] The dust cup structure provided by the present application is configured with a water vapor separation element for generating centrifugal force through its own rotation, thereby separating gas and liquid in the fluid; a second gap is provided between the first end face and the second bottom wall to prevent the second bottom wall from interfering with the rotation of the water vapor separation element; a first gap is provided between the first end face and the first bottom wall so that the second gap is arranged away from the first bottom wall, thereby reducing the flow rate at the second gap, thereby reducing the pressure difference between the outer side of the second gap and the inner side of the second gap, thereby preventing liquid from being directly sucked into the water vapor separation element through the second gap and then entering the device host. Therefore, the dust cup structure provided by the present application improves the waterproofness of the device host.

[0010] In a possible implementation, the first interval is greater than or equal to 10 mm.

[0011] In this way, the second spacer can be arranged away from the first bottom wall, thereby effectively reducing the pressure difference between the inside and outside of the second spacer, thereby preventing liquid from leaking through the second spacer.

[0012] In a possible implementation, the first exhaust chamber is located in the first cyclone chamber, the driving unit is located in the first exhaust chamber, and the water-gas separation element is disposed around the outer peripheral side of the driving unit.

[0013] In this way, the driving unit is arranged in the first exhaust chamber, and the driving unit can be directly driven to rotate by the fluid, so that the driving unit obtains a larger rotation speed, and then the driving unit drives the water-gas separation element to rotate.

[0014] In a possible implementation, the driving unit includes a power fan blade, and the power fan blade is coaxially connected to the water-gas separation element to drive the water-gas separation element to rotate synchronously.

[0015] In this way, when the driving unit adopts power blades, the power blades can be driven to rotate by the fluid in the first exhaust chamber, and then the water vapor separation element can be driven to rotate synchronously and in the same direction by the power blades, so that the water vapor separation element can separate the gas and liquid in the fluid through its own rotation, thereby reducing the cost and energy consumption of the dust cup structure.

[0016] In a possible implementation, the water-gas separation component further includes a mounting member, which is connected to the second bottom wall, and is located at one end of the first exhaust cavity toward the air outlet, and the power fan blade is rotatably connected to the mounting member.

[0017] In this way, the power fan blades can be rotated in the first exhaust chamber, and then the power fan blades are driven to rotate by the fluid, thereby driving the water-gas separation element coaxially connected to the power fan blades to rotate synchronously to separate the gas and liquid in the fluid.

[0018] In a possible implementation, the driving unit includes a driving motor, the driving motor is located in the first exhaust chamber, and the output shaft of the driving motor extends to the first cyclone chamber to be drivingly connected to the water-gas separation element.

[0019] In this way, a driving motor is used to provide driving force for the water-gas separation element, so that the water-gas separation element can rotate continuously and stably without being limited by the size of the suction force, and the water-gas separation effect is better.

[0020] In a possible implementation, the water vapor separation assembly further includes a support member connected to the cyclone separation assembly, the support member having a motor mounting cavity, the motor mounting cavity being located in the first exhaust cavity, and the drive motor is sealably disposed in the motor mounting cavity.

[0021] In this way, the support member can be used to install the drive motor to the first exhaust cavity, and by sealing the drive motor in the motor installation cavity, the waterproof performance of the drive motor can be improved, which is beneficial to improving the operating stability of the drive motor.

[0022] In a possible implementation, the first exhaust chamber has a communication port, which is connected to the first exhaust chamber and the first cyclone chamber, and at least two communication ports are arranged at intervals along the circumference of the first exhaust chamber.

[0023] In this way, the fluid in the first cyclone chamber can enter the first exhaust chamber through the connecting port, thereby driving the power fan blades to rotate, and then the power fan blades drive the water-gas separation element to rotate, so that the water-gas separation element separates the fluid in the first cyclone chamber into gas and liquid, and this reciprocating cycle is repeated.

[0024] In a possible implementation, the cyclone separation assembly further has a second exhaust chamber, an air inlet end of the second exhaust chamber is connected to the first exhaust chamber, and an air outlet end of the second exhaust chamber is open to be connected to the air outlet.

[0025] In this way, the fluid enters the first cyclone chamber through the air inlet, then enters the first exhaust chamber through the connecting port, then enters the second exhaust chamber from the first exhaust chamber, and finally is discharged from the dust cup structure through the air outlet and enters the equipment main unit.

[0026] In a possible implementation, the second exhaust chamber and the first cyclone chamber are located on opposite sides of the second bottom wall.

[0027] In this way, the structure of the cyclone separation assembly can be made more compact, and the fluid in the first exhaust chamber can directly enter the second exhaust chamber without changing the flow direction, thereby making the flow of the fluid smoother.

[0028] In a possible implementation, the water-gas separation element includes a connecting portion and a separating portion that are coaxially connected, and the driving unit is connected to the connecting portion;

[0029] The separation part is in a cylindrical shape, one end of the separation part facing the air outlet is open, and the first end surface is located at the separation part.

[0030] In this way, the separation part is provided to generate centrifugal force through the rotation of the separation part, thereby performing gas-liquid separation on the fluid, and the connection part is provided for connecting with the driving unit, so that the driving unit drives the connection part to rotate, thereby driving the separation part to rotate.

[0031] In a possible implementation, the side wall of the separation portion has an air inlet hole, and a plurality of air inlet holes are arranged at intervals along the circumference of the separation portion;

[0032] The extending direction of the air inlet hole is consistent with the axial direction of the water-gas separation element, or the extending direction of the air inlet hole is inclined relative to the axial direction of the water-gas separation element.

[0033] In this way, after the fluid is separated into gas and liquid on the outside of the separation part, the liquid settles under the action of its own gravity, and the gas can enter the inside of the separation part through the air inlet hole.

[0034] In a possible implementation, the side wall of the separation portion further has a guide rib, which is located on the side of the air inlet facing the first end surface. The guide rib is inclined relative to the axial direction of the separation portion, and multiple guide ribs are arranged at intervals along the circumference of the separation portion.

[0035] In this way, the guide ribs can guide the fluid above the separation part to the side of the water-gas separation component, so that after the fluid is separated into gas and liquid by the separation part, the gas enters the inner side of the separation part through the air inlet hole. This can prevent the fluid from directly entering the inner side of the water-gas separation component through the second interval, thereby reducing the liquid content of the fluid entering the device host.

[0036] In one possible implementation, the cyclone separation assembly includes a first rotating member and a second rotating member connected to each other, the first cyclone chamber is located on the first rotating member, the first exhaust chamber and the second exhaust chamber are located on the second rotating member, the second cyclone chamber is formed between the first rotating member and the dust cup, and the second cyclone chamber is connected to the first cyclone chamber and the air inlet.

[0037] In this way, the fluid sucked into the dust cup structure first enters the second cyclone chamber through the air inlet for a separation. The solid particles in the fluid can be separated and deposited in the lower part of the second cyclone chamber. After that, the fluid enters the first cyclone chamber for a secondary separation. The secondary separation can separate the liquid in the fluid and settle it in the lower part of the first cyclone chamber. The lower part of the first cyclone chamber is connected to the second cyclone chamber, and the separated liquid enters the lower part of the second cyclone chamber. Finally, the fluid flows into the device main unit through the air outlet, and the fluid entering the device main unit contains less solids and liquids.

[0038] In a second aspect, the present application provides a cleaning device, including a device main body and the dust cup structure provided in the first aspect above, wherein the dust cup structure is connected to the device main body.

[0039] In addition to the technical problems solved by the embodiments of the present application described above, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions, other technical problems that can be solved by the dust cup structure and cleaning equipment provided by the present application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific implementation methods.

[0056] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment 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 construed 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 the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0057] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0058] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0059] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0060] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0061] In the related art, the cleaning device may include a main unit and a dust collecting component. The main unit has a suction component. The negative pressure generated by the suction component can collect dust and other impurities on the ground into the dust collecting component. In order to prevent water on the ground from easily entering the main unit, the dust collecting component may include a separation unit. The separation unit includes a water-blocking wind wheel. The water-blocking wind wheel can generate centrifugal force by its own rotation to separate liquid and gas in the fluid.

[0062] However, there is a gap between the water-blocking wind wheel and the corresponding fixing part. Under the negative pressure of the main engine, the liquid on the outside of the water-blocking wind wheel can easily enter the inside of the water-blocking wind wheel through the gap, which can easily cause water to enter the main engine. This is because there is a pressure difference between the inside and outside of the gap, and the inventors have found that the greater the pressure difference between the inside and outside of the gap, the easier it is for the liquid to be sucked into the main engine through the gap.

[0063] In view of this, the present application provides a dust cup structure and a cleaning device, which forms a first gap between the first end face of the water vapor separation element and the first bottom wall of the first exhaust chamber so that the first end face is arranged away from the first bottom wall, thereby reducing the flow rate at the second gap, and thereby reducing the pressure difference between the inside and outside of the second gap, thereby preventing the fluid on the outside of the water vapor separation element from being directly sucked into the inside of the water vapor separation element through the second gap and then entering the device main unit without gas-liquid separation. As a result, the dust cup structure improves the waterproof performance of the device main unit.

[0064] The specific implementation of the dust cup structure and cleaning device provided in the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0065] Reference Figure 1 and Figure 2 As shown, the cleaning device provided in the present application includes a dust cup structure 10 and a device main body 20, and the dust cup structure 10 is connected to the device main body 20.

[0066] Specifically, a negative pressure motor may be provided in the device host 20, and the negative pressure motor is used to provide suction force to the dust cup structure 10. When cleaning the surface to be cleaned, the fluid enters the dust cup structure 10 through the suction port of the cleaning device and is collected. It should be noted that under the action of the suction force, the mixture of impurities such as gas, water stains, dust and particles sucked into the dust cup structure 10 can be collectively referred to as fluid.

[0067] Among them, the cleaning device can be a vacuum cleaner or a mop, etc., which is not limited in the embodiments of the present application.

[0068] Reference Figures 2 to 8 As shown, the dust cup structure 10 provided in the present application includes a dust cup 100, a cyclone separation assembly 200 and a water vapor separation assembly 300, the dust cup 100 has an air inlet 110 and an air outlet 120, the air inlet 110 and the air outlet 120 are located on both sides of the dust cup 100, the cyclone separation assembly 200 is arranged in the dust cup 100, the cyclone separation assembly 200 has a first cyclone chamber 210 and a first exhaust chamber 220, the first cyclone chamber 210 and the first exhaust chamber 220 are connected in sequence between the air inlet 110 and the air outlet 120.

[0069] The water vapor separation assembly 300 includes a water vapor separation element 310 and a driving unit 320 . The water vapor separation element 310 is located in the first cyclone chamber 210 . The driving unit 320 is connected to the water vapor separation element 310 to drive the water vapor separation element 310 to rotate.

[0070] The end of the water vapor separation element 310 facing the air outlet 120 has a first end face 311, the end of the first exhaust chamber 220 away from the air outlet 120 has a first bottom wall 221, and the end of the first cyclone chamber 210 facing the air outlet 120 has a second bottom wall 211. Along the axial direction of the water vapor separation element 310, there is a first gap between the first end face 311 and the first bottom wall 221, and there is a second gap between the first end face 311 and the second bottom wall 211.

[0071] Specifically, the dust cup 100 can be cylindrical, and the dust cup 100 can also have a dust outlet to clean the dust collected in the dust cup 100. For example, the air inlet 110 and the air outlet 120 can be located on both sides of the dust cup 100. The air inlet 110 is located on the side wall of the dust cup 100 so that the fluid enters the dust cup 100 tangentially through the side of the dust cup 100. The air outlet 120 and the dust outlet can be located at both ends of the dust cup 100 so that the separated gas flows along one axial end of the dust cup 100 to the device host 20, and the collected dust and impurities are poured out from the other axial end of the dust cup 100.

[0072] Since the first cyclone chamber 210 and the first exhaust chamber 220 are connected in sequence between the air inlet 110 and the air outlet 120, under the action of suction force, the fluid can enter the first cyclone chamber 210 and the first exhaust chamber 220 through the air inlet 110, and then flow into the device main unit 20 through the air outlet 120.

[0073] Before entering the first cyclone chamber 210, the fluid can undergo a cyclone separation to separate the solid particles in the fluid, and then settle to the bottom of the dust cup 100 under the action of their own gravity, so as to facilitate subsequent dust cleaning.

[0074] Afterwards, the fluid continues to flow to the first cyclone chamber 210 under the action of suction force. The water vapor separation element 310 located in the first cyclone chamber 210 is driven by the driving unit 320 to rotate relative to the first cyclone chamber 210, so that the water vapor separation element 310 generates a larger centrifugal force through its own rotation, so that the liquid in the fluid is separated and then falls to the lower part of the first cyclone chamber 210 under the action of its own gravity. The lower part of the first rotating wind is connected to the dust outlet, so that the liquid can be cleaned out of the dust cup 100 together with the solid particles.

[0075] It should be noted that, since the water vapor separator 310 needs to rotate relative to the first cyclone chamber 210, in order to prevent the second bottom wall 211 of the first cyclone chamber 210 from hindering the rotation of the water vapor separator 310, a second interval needs to be set between the first end surface 311 of the water vapor separator 310 and the second bottom wall 211 of the first cyclone chamber 210. It can be understood that if there is no second interval between the first end surface 311 and the second bottom wall 211, the first end surface 311 will fit with the second bottom wall 211, and the first end surface 311 There is friction between the second bottom wall 211, which will hinder the rotation of the water vapor separator 310. However, the existence of the second interval will bring a problem. When the pressure difference between the outside of the second interval and the inside of the second interval is large, the liquid on the outside of the water vapor separator 310 is easily sucked into the inside of the water vapor separator 310 through the second interval. That is to say, part of the liquid will not be separated by the water vapor separator 310, but will be directly sucked into the device host 20 through the second interval, thereby causing water to enter the electrical components of the device host 20.

[0076] In order to solve this technical problem, it is necessary to reduce the pressure difference between the outer side of the second interval and the inner side of the second interval. When the pressure difference between the outer side of the second interval and the inner side of the second interval is reduced to a certain extent, the liquid in the fluid will not be directly sucked into the device main unit 20 through the second interval, but will be separated under the centrifugal force of the gas-liquid separation element and deposited in the lower part of the first cyclone chamber 210.

[0077] Since the first exhaust chamber 220 is the main flow channel of the dust cup structure 10 during exhaust, in the present application, the first end face 311 of the water vapor separation element 310 is arranged away from the first bottom wall 221 of the first exhaust chamber 220, so that there is a first gap between the first end face 311 and the first bottom wall 221. In this way, the second gap can be away from the mainstream channel of the first exhaust chamber 220, thereby reducing the flow rate at the second gap.

[0078] According to Bernoulli's principle, the pressure difference on both sides of the second interval is the sum of the resistance of the fluid passing through the water vapor separator 310 and the dynamic pressure on both sides of the second interval, wherein the dynamic pressure on both sides of the second interval is dominant, because the dynamic pressure is positively correlated with the fluid density and the square of the flow velocity. After the flow velocity at the second interval is reduced, the dynamic pressure on both sides of the second interval can be effectively reduced, thereby reducing the pressure difference between the outside of the second interval and the inside of the second interval, thereby preventing the liquid outside the water vapor separator 310 from being directly sucked into the inside of the water vapor separator 310 through the second interval without separation. Therefore, the dust cup structure 10 improves the waterproof performance of the device host 20.

[0079] It should be understood that the outer side of the second interval is the outer side of the water-gas separation element 310 , and the inner side of the second interval is the inner side of the water-gas separation element 310 .

[0080] The dust cup structure 10 provided in the embodiment of the present application includes a dust cup 100, a cyclone separation assembly 200 and a water vapor separation assembly 300, the dust cup 100 includes an air inlet 110 and an air outlet 120, the cyclone separation assembly 200 includes a first cyclone chamber 210 and a first exhaust chamber 220, the water vapor separation assembly 300 includes a water vapor separation element 310 and a drive unit 320, the water vapor separation element 310 includes a first end face 311, the first exhaust chamber 220 includes a first bottom wall 221, and the first cyclone chamber 210 includes a second bottom wall 211. A water vapor separator 310 is provided to generate centrifugal force through its own rotation to separate gas and liquid in the fluid; a second gap is provided between the first end face 311 and the second bottom wall 211 to prevent the second bottom wall 211 from interfering with the rotation of the water vapor separator 310; a first gap is provided between the first end face 311 and the first bottom wall 221 so that the second gap is arranged away from the first bottom wall 221, thereby reducing the flow rate at the second gap, thereby reducing the pressure difference between the outside of the second gap and the inside of the second gap, thereby preventing the liquid from being directly sucked into the water vapor separator 310 through the second gap and then entering the device main unit 20. Therefore, the dust cup structure 10 provided in the embodiment of the present application improves the waterproofness of the device main unit 20.

[0081] In a possible implementation, the first interval is greater than or equal to 10 mm. If the first interval is less than 10 mm, the pressure difference on both sides of the second interval can still drive the liquid on the outside of the water-gas separator 310 to enter the inside of the water-gas separator 310 through the second interval. Therefore, setting the first interval to be greater than 10 mm can make the second interval away from the first bottom wall 221, thereby effectively reducing the pressure difference between the inside and outside of the second interval, thereby preventing liquid from leaking through the second interval.

[0082] Exemplarily, the first interval may be any one of 10 mm, 12 mm, 15 mm, 17 mm, and 20 mm, or may be within a range of any two values.

[0083] In some embodiments, the first exhaust chamber 220 is located in the first cyclone chamber 210 , the driving unit 320 is located in the first exhaust chamber 220 , and the water-gas separation element 310 is disposed around the outer peripheral side of the driving unit 320 .

[0084] That is to say, the first cyclone chamber 210 and the first exhaust chamber 220 are arranged in an inner-outer relationship, so that the dust cup structure 10 can be made more compact to reduce the volume of the dust cup structure 10. It can be understood that since the first exhaust chamber 220 is the mainstream channel of the dust cup structure 10, the fluid flow rate of the first exhaust chamber 220 is relatively large, and the drive unit 320 is arranged in the first exhaust chamber 220, and the drive unit 320 can be directly driven to rotate by the fluid, so that the drive unit 320 obtains a relatively large rotation speed, and then the drive unit 320 drives the water vapor separator 310 to rotate.

[0085] Reference Figures 3 to 5 As shown, in some embodiments, the driving unit 320 includes a power fan blade 321, and the power fan blade 321 is coaxially connected to the water-gas separation element 310 to drive the water-gas separation element 310 to rotate synchronously.

[0086] In this way, when the driving unit 320 adopts the power fan blades 321, the power fan blades 321 can be driven to rotate by the fluid in the first exhaust chamber 220, and then the water vapor separation element 310 can be driven to rotate synchronously and in the same direction by the power fan blades 321, so that the water vapor separation element 310 can separate the gas and liquid in the fluid through its own rotation, thereby reducing the cost and energy consumption of the dust cup structure 10.

[0087] Reference Figures 3 to 5 As shown, in a possible implementation, the water vapor separation assembly 300 also includes a mounting member 330 , which is connected to the second bottom wall 211 , and the mounting member 330 is located at one end of the first exhaust chamber 220 facing the air outlet 120 , and the power fan blade 321 is rotatably connected to the mounting member 330 .

[0088] In this way, the power blade 321 can be rotated and arranged in the first exhaust chamber 220, and then the power blade 321 can be rotated under the drive of the fluid, thereby driving the water-gas separation element 310 coaxially connected to the power blade 321 to rotate synchronously to separate the gas and liquid in the fluid.

[0089] Reference Fig. 9 As shown, in other embodiments, the driving unit 320 includes a driving motor 322 , which is located in the first exhaust chamber 220 , and an output shaft of the driving motor 322 extends to the first cyclone chamber 210 to be driven and connected to the water-gas separation element 310 .

[0090] Compared with the method of using the suction force of the device main body 20 to drive the water vapor separation element 310 to rotate, in the above-mentioned setting method, a driving motor 322 is used to provide driving force for the water vapor separation element 310, so that the water vapor separation element 310 can rotate continuously and stably without being limited by the suction force, and the water vapor separation effect is better.

[0091] Reference Fig. 9 As shown, in a possible implementation, the water vapor separation assembly 300 also includes a support member 340, which is connected to the cyclone separation assembly 200, and the support member 340 has a motor installation cavity 341, which is located in the first exhaust cavity 220, and the drive motor 322 is sealed in the motor installation cavity 341.

[0092] In this way, the support member 340 can be used to install the drive motor 322 to the first exhaust cavity 220, and by sealing the drive motor 322 in the motor installation cavity 341, the waterproof performance of the drive motor 322 can be improved, which is beneficial to improving the operating stability of the drive motor 322.

[0093] In some embodiments, the first exhaust cavity 220 has a communication port 222 , which is connected to the first exhaust cavity 220 and the first cyclone cavity 210 , and at least two communication ports 222 are arranged at intervals along the circumference of the first exhaust cavity 220 .

[0094] Thus, the fluid in the first cyclone chamber 210 can enter the first exhaust chamber 220 through the connecting port 222, thereby driving the power fan blades 321 to rotate, and then the power fan blades 321 drive the water-gas separation element 310 to rotate, so that the water-gas separation element 310 separates the fluid in the first cyclone chamber 210 into gas and liquid, and the cycle repeats.

[0095] The communication port 222 is not only located at the bottom of the first exhaust cavity 220 , but also located at the side of the first exhaust cavity 220 .

[0096] Reference Figure 2 , Figure 4 , Figure 5 , Figure 7 and Fig. 9 As shown, in some embodiments, the cyclone separation assembly 200 further has a second exhaust chamber 230 , the air inlet end of the second exhaust chamber 230 is connected to the first exhaust chamber 220 , and the air outlet end of the second exhaust chamber 230 is open to communicate with the air outlet 120 .

[0097] That is to say, the fluid flow path of the dust cup structure 10 is that the fluid enters the first cyclone chamber 210 through the air inlet 110, then enters the first exhaust chamber 220 through the connecting port 222, and then enters the second exhaust chamber 230 from the first exhaust chamber 220, and finally discharges the dust cup structure 10 through the air outlet 120 and enters the equipment main unit 20.

[0098] In a possible implementation, the second exhaust chamber 230 and the first cyclone chamber 210 are located on opposite sides of the second bottom wall 211 .

[0099] In this way, when the first exhaust chamber 220 is located in the first cyclone chamber 210, and the second exhaust chamber 230 and the first cyclone chamber 210 are located on opposite sides of the second bottom wall 211, the structure of the cyclone separation assembly 200 can be made more compact, and the fluid in the first exhaust chamber 220 can directly enter the second exhaust chamber 230 without changing the flow direction, thereby making the flow of the fluid smoother.

[0100] Reference Figure 6As shown, in a specific implementation, the water vapor separator 310 includes a coaxially connected connecting portion 312 and a separating portion 313, and the driving unit 320 is connected to the connecting portion 312. The separating portion 313 is cylindrical, and one end of the separating portion 313 is open toward the air outlet 120, and the first end surface 311 is located at the separating portion 313.

[0101] In this way, the separation part 313 is provided to generate centrifugal force through the rotation of the separation part 313, thereby performing gas-liquid separation on the fluid, and the connection part 312 is provided to be connected to the driving unit 320, so that the driving unit 320 drives the connection part 312 to rotate, thereby driving the separation part 313 to rotate. After the fluid is separated into gas and liquid on the outside of the separation part 313, the liquid falls due to its own gravity, and the gas enters the inside of the separation part 313 and is discharged from the separation part 313 toward one end of the gas outlet 120 through the separation part 313.

[0102] Reference Figure 6 As shown, in a possible implementation, the side wall of the separation portion 313 has an air inlet hole 3131, and a plurality of air inlet holes 3131 are arranged at intervals along the circumference of the separation portion 313. The extending direction of the air inlet hole 3131 is consistent with the axial direction of the water-gas separation element 310, or the extending direction of the air inlet hole 3131 is inclined relative to the axial direction of the water-gas separation element 310.

[0103] With such arrangement, after the fluid is separated into gas and liquid on the outer side of the separation part 313 , the liquid settles under the action of its own gravity, and the gas can enter the inner side of the separation part 313 through the air inlet 3131 .

[0104] When the dust cup structure 10 uses a driving motor 322 to provide power for the water vapor separation element 310, since the water vapor separation element 310 can obtain a higher rotation speed through the driving motor 322, thereby generating a larger centrifugal force, at this time, the extension direction of the air inlet 3131 can be consistent with the axial direction of the water vapor separation element 310.

[0105] When the dust cup structure 10 uses the power fan blades 321 to provide power for the water vapor separation element 310, since the rotation speed of the water vapor separation element 310 depends on the suction force of the negative pressure motor, at this time, the extension direction of the air inlet 3131 can be set to be inclined relative to the axial direction of the water vapor separation element 310, thereby making the water vapor separation element 310 have a better gas-liquid separation effect.

[0106] Reference Figure 6 As shown, in some embodiments, the side wall of the separation portion 313 also has a guide rib 3132, and the guide rib 3132 is located on the side of the air inlet hole 3131 facing the first end surface 311. The guide rib 3132 is inclined relative to the axial direction of the separation portion 313, and multiple guide ribs 3132 are arranged at circumferential intervals along the separation portion 313.

[0107] In this way, the guide rib 3132 can guide the fluid above the separation part 313 to the side of the water-gas separation component 310, so that after the fluid is separated into gas and liquid by the separation part 313, the gas enters the inner side of the separation part 313 through the air inlet hole 3131. In this way, the fluid can be prevented from directly entering the inner side of the water-gas separation component 310 through the second interval, thereby reducing the liquid content of the fluid entering the device host 20.

[0108] Reference Figures 2 to 4 As shown, in a specific implementation, the cyclone separation assembly 200 includes a first rotating member 240 and a second rotating member 250 which are connected to each other, the first cyclone chamber 210 is located on the first rotating member 240, the first exhaust chamber 220 and the second exhaust chamber 230 are located on the second rotating member 250, and a second cyclone chamber is formed between the first rotating member 240 and the dust cup 100, and the second cyclone chamber is connected to the first cyclone chamber 210 and the air inlet 110.

[0109] That is, the fluid sucked into the dust cup structure 10 first enters the second cyclone chamber through the air inlet 110 for primary separation, which can separate the solid particles in the fluid and settle them in the lower part of the second cyclone chamber. After that, the fluid enters the first cyclone chamber 210 for secondary separation, which can separate the liquid in the fluid and settle it in the lower part of the first cyclone chamber 210. The lower part of the first cyclone chamber is connected to the second cyclone chamber, and then the separated liquid enters the lower part of the second cyclone chamber. Finally, the fluid flows into the device main unit 20 through the air outlet 120 and is then discharged from the device main unit 20. In this way, the fluid entering the device main unit 20 contains fewer solids and liquids.

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 replace some or all of the technical features therein with equivalents.
