Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of environmental cleaning appliances, and in particular to a dust cup assembly and a cleaning device. BACKGROUND

[0002] In related technologies, household cleaning devices such as vacuum cleaners and floor washing machines can include a main machine and a dust collection assembly. The main machine has a suction assembly, and the negative pressure generated by the suction assembly can collect dust and other impurities on the ground into the dust collection assembly.

[0003] However, water on the ground is easily sucked into the dust collection assembly along with the airflow, and then enters the main machine, thereby affecting the performance of the electrical components in the main machine. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the present application provides a dust cup assembly and a cleaning device, which has good gas-liquid separation effect and can avoid failure of the main machine of the cleaning device due to water entering.

[0005] In a first aspect, the present application provides a dust cup assembly, which includes a cup body and a cyclone separation piece. The cup body has an air inlet and an air outlet. The cyclone separation piece is arranged in the cup body. The cyclone separation piece includes a connecting portion, a first rotary separation portion, and a water blocking portion. The connecting portion is connected to the cup body. The first rotary separation portion and the water blocking portion are both connected to the connecting portion. The first rotary separation portion has a plurality of filter holes.

[0006] The water blocking portion includes an arc surface plate. The arc surface plate is curved towards the first rotary separation portion. The arc surface plate is arranged around the outside of the first rotary separation portion. At least part of the arc surface plate is arranged between the air inlet and the first rotary separation portion.

[0007] The dust cup assembly provided by the present application is used for making the fluid enter the cup body through the air inlet, making the separated fluid exit the cup body through the air outlet, connecting the cup body through the connecting portion, and then installing the cyclone separation piece into the cup body, intercepting the solid in the fluid through the first rotary separation portion, and then separating the solid, so as to avoid the main machine from being stuck due to the solid entering the main machine. The arc surface plate curved towards the center of the first rotary separation portion is arranged between the air inlet and the first rotary separation portion, so that the airflow entering from the air inlet first rotates around the circumference of the arc surface plate instead of directly passing through the filter holes. In this way, the liquid in the fluid is separated, and then the solid in the fluid is separated through the first rotary separation portion, thereby avoiding the liquid from entering the main machine along with the gas, so that the failure of the main machine due to water entering can be avoided. In a possible implementation manner, the water blocking portion further includes a flat plate. The flat plate is connected to the arc surface plate and located at the end of the arc surface plate away from the air inlet.

[0008] Thus, in the process of rotational separation, part of the liquid will be separated from the arc panel under the combined action of centrifugal force and gravity, and deposited in the cup, and part of the liquid will be attached to the arc panel and move to the end of the arc panel with the airflow. Since the flat panel changes the movement trend of the liquid, the liquid can be more easily separated from the flat panel, so that this part of the liquid can be settled under the action of gravity.

[0009] In a possible implementation, the end of the arc panel away from the air inlet has a water guide groove extending along the axial direction of the first rotational separation part.

[0010] Thus, in the process of rotational separation, part of the liquid will be separated from the arc panel under the combined action of centrifugal force and gravity, and deposited in the cup, and part of the liquid will be attached to the arc panel and move to the end of the arc panel with the airflow. Since the flat panel changes the movement trend of the liquid, the liquid can be more easily separated from the flat panel, so that this part of the liquid can be settled under the action of gravity.

[0011] In a possible implementation, the central angle of the arc panel is greater than or equal to 90° and less than or equal to 150°.

[0012] Thus, the arc panel can have a large enough outer surface, so that after the arc panel is arranged between the air inlet and the first rotational separation part, the arc panel can completely block the air inlet, and the fluid can also rotate around the circumference of the arc panel after being fully rotated, and then pass through the filter hole into the first rotational separation part, thereby improving the gas-liquid separation effect of the arc panel.

[0013] In a possible implementation, the projection of the arc panel on the reference plane covers the projection of the air inlet on the reference plane; wherein the reference plane is perpendicular to the extension direction of the air inlet.

[0014] Thus, the mixed fluid of the mixed gas, liquid and solid can first contact the arc panel, thereby preventing the mixed fluid from entering the space between the arc panel and the first rotational separation part, so that the fluid is fully rotated around the circumference of the arc panel to fully separate the liquid in the fluid.

[0015] In a possible implementation, the side of the arc panel facing the air inlet has a first side edge, a transition edge and a second side edge, the first side edge extends along the axial direction of the first rotational separation part, the second side edge extends along the circumferential direction of the first rotational separation part, the transition edge is arc-shaped, and the transition edge is connected between the first side edge and the second side edge.

[0016] In this way, the transition edge is not easy to get caught on objects, so that when the mixed fluid enters the cup body from the air inlet, the solids in the mixed fluid will not be caught by the arc panel, and the mixed fluid can smoothly rotate and separate around the circumference of the first rotating separation part.

[0017] In a possible implementation, both ends of the curved plate along the axial direction of the first rotary separation portion extend beyond both ends of the axial direction of the first rotary separation portion.

[0018] In this way, the projection of the arc panel on the outer peripheral wall of the first rotating separation part can completely cover the axial ends of the first rotating separation part, thereby preventing the mixed fluid from directly passing through the filter hole without gas-liquid separation when entering the cup body from the air inlet, thereby improving the gas-liquid separation effect of the arc panel.

[0019] In a possible implementation, the air inlet is located at one circumferential side of the first rotary separation portion, and the air outlet is located at one axial end of the first rotary separation portion.

[0020] In this way, the fluid can move radially along the first rotary separation portion, enter the cup body from the air inlet, then be tangential to the arc panel and rotate around the circumference of the first rotary separation portion for separation. It can then move axially along the first rotary separation portion and flow out of the cup body from the air outlet at one axial end of the first rotary separation portion, thereby making the flow of the fluid smoother. In one possible implementation, the cyclone separator also includes a second rotary separation portion, which is coaxially connected to the first rotary separation portion and is located at the end of the first rotary separation portion that is away from the air outlet.

[0021] In this way, the filter holes of the first rotary separation part can intercept and filter out larger particles of solids, and the second rotary separation part further separates the solids in the fluid to separate small particles of solids in the fluid. The second rotary separation part can improve the gas-solid separation effect of the cyclone separator.

[0022] In a possible implementation, the end of the connecting portion facing the air outlet has a first positioning portion, the end of the cup body facing the air outlet has a second positioning portion, and the first positioning portion is connected to the second positioning portion.

[0023] In this way, through the cooperation between the first positioning part and the second positioning part, after the cyclone separator is installed in the cup body, the arc panel can be blocked between the air inlet and the first rotary separation part. Moreover, the first positioning part and the second positioning part can improve the installation accuracy and efficiency of the cyclone separator.

[0024] In a second aspect, the present application provides a cleaning device, comprising a main unit and the dust cup assembly provided in the first aspect, wherein the dust cup assembly is connected to the main unit.

[0025] Therefore, the dust cup assembly can avoid the host from malfunctioning due to water absorption.

[0026] In a possible implementation, the host includes a shell and a fan assembly, the cup body is connected to the shell, the fan assembly is arranged in the shell, and the fan assembly is communicated with the air outlet.

[0027] Therefore, the fan assembly can generate negative pressure when working, so that the host can provide suction force for the dust cup assembly to suck the dirt into the cup body and make the clean gas enter the fan assembly after sufficient rotational separation in the cup body, and then the clean gas is discharged from the fan assembly, so as to avoid the solid and liquid from affecting the normal work of the fan assembly.

[0042] To make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more details below with reference to the drawings in the preferred embodiments of the present application. In the drawings, the same or similar notations represent the same or similar parts or parts having the same or similar functions throughout. The described embodiments are part of the embodiments of the present application, rather than all the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0043] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, can be fixed connection, can be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0044] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the drawings, and are only intended to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0045] The terms "first", "second", "third" (if any) in the description and claims of this application and the above drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the application described herein can be implemented in an order other than that illustrated or described herein.

[0046] In addition, the terms "include" and "have" and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or display that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products, or displays.

[0047] In the related art, household cleaning equipment such as a vacuum cleaner, a scrubber, etc. can include a main machine and a dust collection assembly, the main machine has a suction assembly, and the negative pressure generated by the suction assembly can collect dust and other impurities on the ground into the dust collection assembly.

[0048] However, water on the ground is easy to be sucked into the dust collection assembly along with the airflow, and then into the main machine, thereby affecting the performance of the electrical devices in the main machine. For a scrubber, it not only needs to perform dry suction operation on the ground, but also needs to perform wet mopping operation on the ground. Therefore, the scrubber is usually provided with a mopping functional assembly. Although the water content of the mopping functional assembly can be reduced by controlling the water spraying amount of the mopping functional assembly, thereby reducing the water amount on the ground, a large amount of water is needed to quickly wet the dry mop at the initial stage of use. Thus, after multiple starts, the water content of the mopping functional assembly is high, and the reciprocating push-pull in the same area also increases the water amount on the ground, thereby causing the main machine to suck water.

[0049] In the related art, a sewage tank is added to the floor brush to preliminarily separate the sucked water, thereby reducing the water suction amount of the rear-end dust collection assembly and the water inlet probability of the main machine. However, due to the volume limitation of the floor brush, the volume of the sewage tank arranged on the floor brush is small, and the gas-liquid separation effect is limited. Meanwhile, the increased volume limits the use scene of the scrubber. In addition, after use, not only the dust collection assembly needs to be cleaned, but also the sewage tank of the floor brush needs to be cleaned, thereby increasing the workload of the user and the cost of the scrubber motor.

[0050] Therefore, the present application provides a dust cup assembly and a cleaning equipment. A water blocking part is arranged between the air inlet of the dust cup assembly and the first rotary separation part. The water blocking part can block the liquid from directly entering the first rotary separation part through the filter hole of the first rotary separation part. The water blocking part can fully separate the gas and liquid in the fluid, and then make the gas enter the first rotary separation part. The gas-liquid separation effect is good, and the main machine of the cleaning equipment can be prevented from being waterlogged and malfunctioning.

[0051] The specific embodiments of the dust cup assembly and the cleaning device provided by the present application are described in detail below with reference to the accompanying drawings.

[0052] Referring to Figure 1 With Figure 2 As shown in the accompanying drawings, the present application provides a cleaning device, which comprises a dust cup assembly 10 and a main machine 20, the dust cup assembly 10 is connected to the main machine 20, the main machine 20 can provide suction force for the cleaning device, so as to suck away dirt on the surface to be cleaned, and the dust cup assembly 10 can collect the dirt.

[0053] Among them, the cleaning device can be a household cleaning device such as a vacuum cleaner or a scrubber, and the present application is not limited thereto.

[0054] Referring to Figures 1 to 7 Based on the above embodiments, the present application further provides a dust cup assembly 10, which comprises a cup body 100 and a cyclone separation piece 200, the cup body 100 has an air inlet 110 and an air outlet 120. The cyclone separation piece 200 is arranged in the cup body 100, and the cyclone separation piece 200 comprises a connecting part 210, a first rotary separation part 220 and a water blocking part 230, the connecting part 210 is connected to the cup body 100, the first rotary separation part 220 and the water blocking part 230 are both connected to the connecting part 210, and the first rotary separation part 220 has a plurality of filter holes.

[0055] The water blocking part 230 comprises an arc surface plate 231, the arc surface plate 231 is curved towards the first rotary separation part 220, the arc surface plate 231 is arranged on the outer side of the first rotary separation part 220, and at least part of the arc surface plate 231 is arranged between the air inlet 110 and the first rotary separation part 220.

[0056] It can be understood that under the action of the suction force, the mixture of gas, water stains, dust and particles and other impurities sucked into the dust cup assembly 10 can be collectively referred to as fluid.

[0057] In the present embodiment, the cup body 100 is used to connect with the main machine 20, so that the dust cup assembly 10 is installed on the main machine 20 as a whole, and the cup body 100 can be used to collect dirt, that is, the fluid enters the cup body 100 from the air inlet 110, and then flows out of the cup body 100 from the air outlet 120, in this process, the cyclone separation piece 200 can separate gas-liquid and gas-solid in the fluid, and the liquid dirt and the solid dirt can be deposited in the cup body 100, while the gas continues to flow and enters the main machine 20, and then is discharged out of the main machine 20.

[0058] In a specific implementation, the cyclone separation piece 200 can include a connecting portion 210 for connecting with the cup body 100, and further mounting the cyclone separation piece 200 as a whole into the cup body 100, wherein the cyclone separation piece 200 can be detachably connected with the cup body 100, and further facilitating the cyclone separation piece 200 to be detached for cleaning. The filtering holes of the first rotary separation portion 220 can intercept large-particle solids in the fluid, and further achieve gas-solid separation. The water-blocking portion 230 can prevent liquid in the fluid from entering the first rotary separation portion 220 through the filtering holes, and further achieve gas-liquid separation. In this way, the cyclone separation piece 200 can effectively separate solids and liquids in the fluid, thereby avoiding the liquid from causing the main machine 20 to short circuit, and avoiding the solids from causing the main machine 20 to jam.

[0059] It should be understood that the first rotary separation portion 220 can be a rotary structure, for example, a cylindrical shape, and the water-blocking portion 230 has an arc surface plate 231 curved towards the center of the first rotary separation portion 220, that is, the arc surface plate 231 can be arranged around the outer peripheral wall of the first rotary separation portion 220, and the center of the arc surface plate 231 and the center of the first rotary separation portion 220 are located on the same side. The arc surface plate 231 and the first rotary separation portion 220 can partially overlap, and the arc surface plate 231 can be arranged between the air inlet 110 and the first rotary separation portion 220.

[0060] In this way, when the fluid enters the cup body 100 from the air inlet 110, the fluid first contacts the outer surface of the arc surface plate 231, and rotates around the circumferential direction of the arc surface plate 231 under the action of the suction force. In this process, the liquid moves towards the outside of the arc surface plate 231 under the action of centrifugal force, and moves towards the bottom of the cup body 100 under the action of its own gravity, and further deposits in the cup body 100. In this way, the liquid in the fluid can be separated out.

[0061] When the fluid continues to move to the end of the water-blocking portion 230 away from the air inlet 110 under the action of the suction force, the fluid moves along the radial direction of the first rotary separation portion 220 while moving along the circumferential direction of the first rotary separation portion 220, so as to pass through the filtering holes and enter the first rotary separation portion 220. The solids in the fluid are intercepted outside the first rotary separation portion 220, so as to achieve gas-solid separation.

[0062] After that, the clean gas can be discharged from the air outlet 120 of the dust cup assembly 10 and enter the main machine 20, and the clean gas will not adversely affect the main machine 20.

[0063] The water-blocking portion 230 is arranged in the cup body 100, and can effectively achieve gas-liquid separation. When cleaning later, the user only needs to clean the dust cup assembly 10, without additional burden on the user, and the structure is relatively simple, thereby reducing the cost of the cleaning equipment.

[0064] The dust cup assembly 10 provided by the embodiment of the present application comprises a cup body 100 and a cyclone separating piece 200. The cup body 100 comprises an air inlet 110 and an air outlet 120. The cyclone separating piece 200 is arranged in the cup body 100. The cyclone separating piece 200 comprises a connecting portion 210, a first rotary separating portion 220 and a water blocking portion 230. The water blocking portion 230 comprises an arc panel 231. The air inlet 110 is arranged to allow fluid to enter the cup body 100 through the air inlet 110. The air outlet 120 is arranged to allow the separated fluid to exit the cup body 100 through the air outlet 120. The connecting portion 210 is arranged to connect with the cup body 100, and then the cyclone separating piece 200 is integrally installed in the cup body 100. The first rotary separating portion 220 is arranged to intercept the solid in the fluid, and then separate the solid, so as to avoid the main machine 20 from being stuck due to the solid entering the main machine 20. The arc panel 231 is arranged between the air inlet 110 and the first rotary separating portion 220 and is curved towards the center of the first rotary separating portion 220, so that the airflow entering from the air inlet 110 firstly rotates around the circumference of the arc panel 231 instead of directly passing through the filter hole. In this way, the liquid in the fluid is separated, and then the solid in the fluid is separated by the first rotary separating portion 220, so as to avoid the liquid entering the main machine 20 with the gas, thereby avoiding the main machine 20 from being malfunctioned due to water entering.

[0065] Referring to Figure 4 With Figure 5 As shown in the figure, in some embodiments, the water blocking portion 230 further comprises a flat panel 232. The flat panel 232 is connected with the arc panel 231, and the flat panel 232 is located at the end of the arc panel 231 away from the air inlet 110.

[0066] It can be understood that the flat panel 232 is arranged at the end of the arc panel 231, and the flat panel 232 can be tangent to the arc panel 231. In the process of rotary separation, part of the liquid will separate from the arc panel 231 under the combined action of the centrifugal force and the gravity of the liquid itself, and deposit in the cup body 100. Part of the liquid will adhere to the arc panel 231 and move to the end of the arc panel 231 with the airflow. Since the flat panel 232 changes the movement trend of the liquid, the liquid can more easily separate from the flat panel 232, so that this part of the liquid can settle under the action of the gravity of the liquid itself.

[0067] Referring to Figure 6 With Figure 7 As shown in the figure, in a possible implementation, the end of the arc panel 231 away from the air inlet 110 has a water guide groove 233. The water guide groove 233 extends along the axial direction of the first rotary separating portion 220.

[0068] That is, in the process of rotary separation, part of the liquid will be separated from the arc panel 231 under the combined action of centrifugal force and gravity, and deposited in the cup 100, and part of the liquid will be attached to the arc panel 231 and move to the end of the arc panel 231 with the airflow. The water guide groove 233 can prevent the liquid attached to the arc panel 231 from continuing to flow, and converge the liquid, so that the liquid flows along the extension direction of the water guide groove 233 under the action of gravity and is deposited at the bottom of the cup 100. In this way, the water guide groove 233 can improve the gas-liquid separation effect of the water blocking part 230.

[0069] In some embodiments, the central angle of the arc panel 231 is greater than or equal to 90° and less than or equal to 150°.

[0070] In this way, the arc panel 231 can have a large enough outer surface, so that after the arc panel 231 is arranged between the air inlet 110 and the first rotary separation part 220, the arc panel 231 can completely block the air inlet 110, and the fluid can also rotate around the circumference of the arc panel 231 after being sufficiently rotated, and then pass through the filter hole into the first rotary separation part 220, thereby improving the gas-liquid separation effect of the arc panel 231.

[0071] The central angle of the arc panel 231 can refer to the angle α in the Figure 5 .

[0072] In a possible implementation, the projection of the arc panel 231 on the reference plane covers the projection of the air inlet 110 on the reference plane. The reference plane is perpendicular to the extension direction of the air inlet 110.

[0073] That is, the arc panel 231 can be completely arranged between the air inlet 110 and the first rotary separation part 220, so that the mixed fluid of the mixed gas, liquid and solid first contacts the arc panel 231, thereby preventing the mixed fluid from entering the space between the arc panel 231 and the first rotary separation part 220, so that the fluid is rotated around the circumference of the arc panel 231 to sufficiently separate the liquid in the fluid.

[0074] Referring to Figure 3 In some embodiments, the side of the arc panel 231 facing the air inlet 110 has a first side edge 2311, a transition edge 2312 and a second side edge 2313. The first side edge 2311 extends along the axial direction of the first rotary separation part 220, the second side edge 2313 extends along the circumferential direction of the first rotary separation part 220, the transition edge 2312 is arc-shaped, and the transition edge 2312 is connected between the first side edge 2311 and the second side edge 2313.

[0075] In this way, the transition edge 2312 is less likely to catch objects, and the mixed fluid can flow smoothly into the cup 100 from the air inlet 110 without being caught by the arc panel 231, so that the mixed fluid can rotate and separate along the circumferential direction of the first rotating separation part 220.

[0076] In one possible implementation, the arc panel 231 extends beyond both axial ends of the first rotating separation part 220.

[0077] In this way, the projection of the arc panel 231 on the outer circumferential wall of the first rotating separation part 220 can completely cover both axial ends of the first rotating separation part 220, so that the mixed fluid can not directly pass through the filter hole without being separated into gas and liquid when flowing into the cup 100 from the air inlet 110. In this way, the gas-liquid separation effect of the arc panel 231 can be improved.

[0078] In some embodiments, the air inlet 110 is located at one side of the circumferential direction of the first rotating separation part 220, and the air outlet 120 is located at one axial end of the first rotating separation part 220.

[0079] In this way, the fluid can flow along the radial direction of the first rotating separation part 220, enter the cup 100 from the air inlet 110, be tangent to the arc panel 231, and rotate and separate along the circumferential direction of the first rotating separation part 220, and then flow along the axial direction of the first rotating separation part 220, and then flow out of the cup 100 from the air outlet 120 at one axial end of the first rotating separation part 220, so that the fluid can flow more smoothly.

[0080] Referring to Figure 3 In one possible implementation, the cyclone separation piece 200 further includes a second rotating separation part 240, the second rotating separation part 240 is coaxially connected with the first rotating separation part 220, and the second rotating separation part 240 is located at one end of the first rotating separation part 220 away from the air outlet 120.

[0081] It can be understood that the filter hole of the first rotating separation part 220 can intercept and filter out larger particles of solid, and after entering the first rotating separation part 220, the solid in the fluid needs to be further separated by the second rotating separation part 240 to separate smaller particles of solid in the fluid, so that the second rotating separation part 240 can improve the gas-solid separation effect of the cyclone separation piece 200.

[0082] Referring to Figure 2 With Figure 3As shown, in some embodiments, the end of the connecting portion 210 facing the air outlet 120 has a first positioning portion 211, and the end of the cup body 100 facing the air outlet 120 has a second positioning portion 130, and the first positioning portion 211 is connected with the second positioning portion 130.

[0083] In this way, through the cooperation between the first positioning portion 211 and the second positioning portion 130, after the cyclone separating piece 200 is installed to the cup body 100, the arc panel 231 can be arranged between the air inlet 110 and the first rotary separating portion 220, and the first positioning portion 211 and the second positioning portion 130 can improve the installation accuracy and efficiency of the cyclone separating piece 200.
