Description

TECHNICAL FIELD

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

[0002] In related technologies, household cleaning devices such as vacuum cleaners can include a main machine and a dust collection assembly. The main machine has a suction assembly. The negative pressure generated by the suction assembly can collect dust and other impurities on the ground into the dust collection assembly. The dust collection assembly includes a dust cup and a filter screen. The filter screen is in the shape of a cylinder and is arranged in the dust cup. The dust cup has an air inlet and an air outlet. After the airflow enters, it rotates around the filter screen in the dust cup, and then centrifugal separation is performed. The separated airflow passes through the filter screen and is discharged from the dust air outlet. The dust and other particulate matter separated by centrifugal separation is deposited at the bottom of the dust cup.

[0003] Because the airflow in the dust cup is in a high-speed rotating state, the dust deposited at the bottom of the dust cup will also rotate and move under the influence of the high-speed airflow, thereby making it easy for the dust to be lifted, thereby reducing the dust deposition effect of the dust cup. Utility model content

[0004] Therefore, the present application provides a dust cup structure and a cleaning device, which has good dust collection effect.

[0005] In a first aspect, the present application provides a dust cup structure, which includes a first cup body, a second cup body, a cyclone cylinder, and a baffle. The first cup body has an air inlet and an air outlet, and the air outlet is located at one end of the first cup body. The second cup body is connected in the first cup body, and a dust storage cavity is defined between the first cup body and the second cup body. The second cup body has a dust throwing port.

[0006] The cyclone cylinder is connected in the second cup body, and a separation cavity is defined between the cyclone cylinder and the second cup body. The cyclone cylinder has an air outlet cavity and an air outlet. The air outlet is located at one end of the cyclone cylinder. The air inlet, the separation cavity, the air outlet cavity, the air outlet, and the air outlet are sequentially connected. The dust throwing port is connected to the separation cavity and the dust storage cavity.

[0007] The baffle is connected to one end of the second cup body away from the air outlet. One end of the baffle away from the second cup body has a first distance T1 from the bottom wall of the first cup body away from the air outlet. The first distance T1 satisfies: T1≤25mm.

[0008] The dust cup structure provided by the application is used for jointly defining the dust storage cavity by the first cup body and the second cup body, so that the dust storage cavity collects separated dust and the like solid, is used for jointly defining the separation cavity by the second cup body and the cyclone barrel, so that the fluid is centrifugally separated in the separation cavity, is used for allowing the fluid to enter the dust cup structure by the air inlet, is used for allowing the fluid to flow after being centrifugally separated by the air outlet cavity and the air outlet, is used for allowing the separated fluid to flow out of the dust cup structure by the air outlet, is used for connecting the dust storage cavity and the separation cavity by the dust discharging port, so that the dust and the like solid centrifugally separated in the separation cavity enters the dust storage cavity to be deposited, is used for preventing the dust and the like solid already deposited at the bottom of the dust storage cavity from flowing back under the influence of the airflow by the baffle, and the first distance T1 between the end of the baffle away from the second cup body and the bottom wall of the first cup body away from the air outlet satisfies T1≤25mm, so that the baffle can effectively prevent the dust and the like solid from moving towards the dust discharging port. Therefore, the dust collecting effect of the dust cup structure provided by the application is good.

[0009] In a possible implementation, the dust storage cavity includes a first dust storage cavity and a second dust storage cavity in communication with each other, the first dust storage cavity is arranged along the radial direction of the cyclone barrel with the separation cavity, and the second dust storage cavity is arranged along the axial direction of the cyclone barrel with the separation cavity. The second dust storage cavity is located at the bottom of the separation cavity away from the air outlet, and the baffle is arranged between the first dust storage cavity and the second dust storage cavity.

[0010] In this way, when the dust and the like solid are deposited at the bottom of the second dust storage cavity, the baffle arranged between the first dust storage cavity and the second dust storage cavity can effectively prevent the dust deposited in the second dust storage cavity from moving to the first dust storage cavity, thereby avoiding the dust from flowing back to the separation cavity through the dust discharging port, and improving the dust collecting effect of the dust storage cavity.

[0011] In a possible implementation, the baffle extends along the axial direction of the cyclone barrel.

[0012] In this way, the baffle and the side wall of the second cup body can be integrally formed during processing, thereby simplifying the processing process, and the baffle extends along the axial direction of the cyclone barrel, which can improve the blocking effect of the baffle on the dust.

[0013] In a possible implementation, the cyclone barrel includes a filter screen, and the filter screen is arranged at least on the peripheral wall of the cyclone barrel to communicate the separation cavity and the air outlet cavity.

[0014] In this way, when the fluid is centrifugally separated in the separation cavity, the dust and the like large-particle solid in the fluid can be separated out, the fluid after being centrifugally separated can pass through the filter screen, and then enter the air outlet cavity, and then flow along the air outlet and the air outlet in turn.

[0015] In a possible implementation, the filter screen includes a first filter screen and a second filter screen, the first filter screen is arranged on the side wall of the cyclone barrel to communicate the separation cavity and the dust storage cavity, and the second filter screen is arranged on the bottom wall of the cyclone barrel away from the air outlet to communicate the dust storage cavity and the air outlet cavity.

[0016] In this way, part of the airflow enters the air outlet cavity under the action of suction through the first filter screen, and then flows along the air outlet and the air outlet, and is discharged from the dust cup structure. Another part of the airflow can flow along the dust discharge port, the first dust storage cavity, the second dust storage cavity, the air outlet cavity, the air outlet and the air outlet in sequence under the action of suction, so that the airflow can drive the dust and other solids to flow to the bottom of the first dust storage cavity and the second dust storage cavity, and then the dust and other solids are deposited at the bottom of the second dust storage cavity, thereby improving the dust collection effect of the dust cup structure.

[0017] In a possible implementation, the ventilation area of the first filter screen is greater than the ventilation area of the second filter screen.

[0018] In this way, most of the airflow flows along the air inlet, the separation cavity, the air outlet cavity, the air outlet and the air outlet, thereby avoiding reducing the suction of the dust cup structure, and a small part of the airflow flows along the air inlet, the separation cavity, the dust discharge port, the dust storage cavity, the second dust storage cavity, the air outlet cavity, the air outlet and the air outlet, thereby improving the dust collection effect of the dust storage cavity.

[0019] In a possible implementation, the dust cup structure further includes a guide assembly, the guide assembly is arranged at the air outlet, the guide assembly includes a guide piece and a plurality of support ribs, the plurality of support ribs are arranged at intervals along the circumference of the guide piece, the support ribs are connected between the outer circumferential wall of the guide piece and the inner circumferential wall of the air outlet, and the guide piece, the support ribs and the air outlet define a guide channel.

[0020] In this way, the support ribs can be connected to the first cup body, and the guide piece, the air outlet and the plurality of support ribs define a plurality of guide channels. When the airflow passes through the plurality of guide channels, the airflow can be dispersed, thereby reducing the flow speed of the airflow. The guide piece can change the flow direction of the airflow, so that the airflow can uniformly pass through each area of the first filter assembly at a lower flow rate when flowing to the downstream first filter assembly, thereby improving the filtering effect of the first filter assembly.

[0021] In a possible implementation, the side of the guide piece away from the air outlet has a guide curved surface, and the guide curved surface is used to guide the fluid to flow along the radial direction of the cyclone barrel.

[0022] In this way, the guide curved surface can gradually change the flow direction of the airflow from the axial direction of the cyclone barrel to each radial direction of the cyclone barrel, thereby dispersing the flow direction of the airflow and uniformly reducing the flow rate of the airflow.

[0023] In a possible implementation, the flow guide member includes a first flow guide part and a second flow guide part connected to each other, the first flow guide part is in a conical shape, and an end of the first flow guide part close to the air outlet is larger than an end of the first flow guide part away from the air outlet.

[0024] The second flow guide part is connected to the end of the first flow guide part close to the air outlet and is folded towards the outside of the first flow guide part.

[0025] In this way, the side of the flow guide member away from the air outlet forms a flow guide curved surface, which can guide the flow direction of the fluid to gradually change from the axial direction of the cyclone barrel to each radial direction of the cyclone barrel, thereby gently changing the flow direction of the air flow, and in the process, the flow guide curved surface can cooperate with the air guide channel to disperse a large air flow into multiple small air flows and then flow out, thereby reducing the flow rate of the fluid.

[0026] In a possible implementation, the dust cup structure further includes a first filter assembly and a second filter assembly, the first cup body further has a mounting cavity, the mounting cavity and the dust storage cavity are separated by a partition plate, the dust storage cavity and the mounting cavity are located at two ends of the first cup body, and the air outlet is located at an end of the mounting cavity away from the dust storage cavity.

[0027] The first filter assembly and the second filter assembly are both arranged in the mounting cavity, and the first filter assembly is located on the side of the second filter assembly away from the air outlet.

[0028] In this way, the partition plate can separate the mounting cavity and the dust storage cavity to prevent dust and other solids in the dust storage cavity from entering the mounting cavity, the first filter assembly can perform a second separation and filtration on the fluid, and the second filter assembly can perform a third separation and filtration on the fluid, which is then discharged from the air outlet, so that the fluid can be filtered and separated at least three times when flowing in the dust cup structure in combination with the initial centrifugal separation of the fluid in the separation chamber, thereby effectively improving the dust and gas separation effect of the dust cup structure and preventing dust from entering the main machine or backflowing to the environment.

[0029] In a possible implementation, in the axial direction of the cyclone barrel, the first filter assembly and the flow guide member have a second spacing T2, and the second spacing T2 satisfies T2≥5mm.

[0030] In this way, the air flow can be uniformly distributed on the first filter assembly and the contact time of the air flow with the first filter assembly can be increased, thereby improving the filtration and separation effect of the first filter assembly.

[0031] In a possible implementation, the diameter d of the cyclone barrel and the diameter D of the second cup body satisfy d / D≤1 / 2, and / or the distance between the inner circumferential wall of the second cup body and the outer circumferential wall of the cyclone barrel is greater than or equal to 20mm.

[0032] Thus, when the diameter d of the cyclone cylinder and the diameter D of the second cup body satisfy d / D≤1 / 2, the rotation radius of the fluid can be increased, and the centrifugal force of the fluid can be increased, thereby improving the centrifugal separation effect of the separation cavity. When the distance between the inner circumferential wall of the second cup body and the outer circumferential wall of the cyclone cylinder is greater than or equal to 20mm, the distance between the cyclone cylinder and the second cup body in the radial direction can be increased, and thus the fluid can rotate away from the cyclone cylinder under the action of inertia after entering the separation cavity, thereby avoiding solid blockage of the filter screen.

[0033] In a second aspect, the application provides a cleaning device, comprising a main machine and the dust cup structure provided in the first aspect.

DETAILED DESCRIPTION

[0044] In order 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 detail below with reference to the drawings of the preferred embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill 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.

[0045] 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 internal communication of two elements or interaction relationship between two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0046] 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 devices or elements 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.

[0047] The terms "first", "second", "third" (if present) in the specification and claims of this application and the above drawings are used to distinguish similar objects, and do not necessarily have to be used 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, for example, in an order other than that illustrated or described herein.

[0048] 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.

[0049] In the related art, a household cleaning device such as a vacuum cleaner can include a main machine and a dust collection assembly, the main machine has a suction assembly, the negative pressure generated by the suction assembly can collect dust and other impurities on the ground into the dust collection assembly. The dust collection assembly includes a dust cup and a filter screen, the filter screen is in a cylindrical shape and is arranged in the dust cup, the dust cup has an air inlet and an air outlet, so that the airflow enters the dust cup and rotates around the filter screen, and then centrifugal separation is performed. The separated airflow passes through the filter screen and is discharged from the dust outlet. The dust and other particulate matter separated by centrifugal separation is deposited at the bottom of the dust cup.

[0050] Because the airflow in the dust cup is in a high-speed rotating state, the dust deposited at the bottom of the dust cup will also rotate and move under the influence of the high-speed airflow, thereby making the dust easy to be lifted up, thereby reducing the deposition effect of the dust cup.

[0051] Therefore, the dust cup structure and the cleaning device provided by the embodiments of the present application effectively prevent the dust and other solids that have been deposited at the bottom of the dust storage cavity from flowing back, thereby improving the dust collection effect of the dust cup structure.

[0052] The specific implementation of the dust cup structure and the cleaning device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0053] Referring to Figure 1 As shown in the drawings, the embodiments of the present application provide a cleaning device, which includes a main machine and a dust cup structure, and the dust cup structure is connected with the main machine. The main machine can provide suction force for the cleaning device, thereby sucking away dust and other particulate matter on the surface to be cleaned, and the dust cup assembly can separate, deposit and store the dust.

[0054] Among them, the cleaning device can be a household cleaning device such as a vacuum cleaner, a scrubber, etc., which is not limited by the embodiments of the present application.

[0055] Referring to Figures 1 to 3 On the basis of the above-mentioned embodiments, the dust cup structure provided by the embodiments of the present application further comprises a first cup body 100, a second cup body 200, a cyclone barrel 400 and a baffle 600. The first cup body 100 has an air inlet 110 and an air outlet 120, and the air outlet 120 is located at one end of the first cup body 100. The second cup body 200 is connected in the first cup body 100, and a dust storage cavity 300 is defined between the first cup body 100 and the second cup body 200. The second cup body 200 has an ash throwing port 210.

[0056] The cyclone barrel 400 is connected in the second cup body 200, and a separation cavity 500 is defined between the cyclone barrel 400 and the second cup body 200. The cyclone barrel 400 has an air outlet cavity 410 and an air outlet 420, and the air outlet 420 is located at one end of the cyclone barrel 400. The air inlet 110, the separation cavity 500, the air outlet cavity 410, the air outlet 420 and the air outlet 120 are sequentially communicated, and the ash throwing port 210 communicates the separation cavity 500 and the dust storage cavity 300.

[0057] The baffle 600 is connected to one end of the second cup body 200 away from the air outlet 120. One end of the baffle 600 away from the second cup body 200 has a first distance T1 from the bottom wall of the first cup body 100 away from the air outlet 120, and the first distance T1 satisfies T1≤25mm.

[0058] In the embodiments, the first cup body 100 and the second cup body 200 can be in an inner-outer nested structure, so that the dust storage cavity 300 is arranged around the outer periphery of the separation cavity 500. Alternatively, the side wall of the first cup body 100 and the side wall of the second cup body 200 can be arranged along the radial direction of the cyclone barrel 400, and the bottom wall of the first cup body 100 and the bottom wall of the second cup body 200 can be arranged along the axial direction of the cyclone barrel 400, so that the dust storage cavity 300 including a first dust storage cavity 310 and a second dust storage cavity 320 is formed between the first cup body 100 and the second cup body 200. The first dust storage cavity 310 and the separation cavity 500 are arranged side by side along the radial direction of the cyclone barrel 400, and the second dust storage cavity 320 and the separation cavity 500 are arranged side by side along the axial direction of the cyclone barrel 400, for example Figure 2 the dust cup structure shown in the drawings.

[0059] It can be understood that under the suction of the host, the fluid enters the separation cavity 500 through the air inlet 110, and rotates around the cyclone cylinder 400 with the cyclone cylinder 400 as the rotation center, and further generates centrifugal force, so as to separate the large particle solid in the fluid by the combined action of centrifugal force and gravity in the process of rotation. The large particle solid in the separation cavity 500 can enter the dust storage cavity 300 through the dust discharging port 210, and then deposit at the bottom of the dust storage cavity 300. Then, the fluid separated for the first time can flow along the air outlet cavity 410, the air outlet 420 and the air outlet 120 in turn.

[0060] Due to the action of the airflow, the dust and other solids that have been deposited at the bottom of the dust storage cavity 300 will flow back to the dust discharging port 210 under the driving of the airflow. Therefore, the dust cup structure of the present embodiment sets the baffle 600 at the end of the second cup body 200 away from the air outlet 120, which can prevent the large particle solids deposited in the dust storage cavity 300 from moving towards the dust discharging port 210, thereby avoiding the large particle solids flowing back to the separation cavity 500 through the dust discharging port 210, so as to avoid affecting the dust-air separation effect of the separation cavity 500 and the dust collection effect of the dust storage cavity 300.

[0061] It should be noted that when the distance T1 between the end of the baffle 600 away from the second cup body 200 and the bottom wall of the first cup body 100 away from the air outlet 120 is large, that is, the distance between the end of the baffle 600 away from the second cup body 200 and the bottom wall of the dust storage cavity 300 is large, when the airflow is strong, the blocking effect of the baffle 600 on the dust and other solids is effective. Therefore, in order to improve the blocking effect of the baffle 600, T1 can be less than or equal to 250㎜ in specific implementation. In this way, the dust and other solids can be effectively blocked from moving towards the dust discharging port 210, and the first spacing formed between the end of the baffle 600 away from the second cup body 200 and the bottom wall of the first cup body 100 away from the air outlet 120 can allow the airflow to drive the dust to pass through, thereby allowing the dust to deposit at the bottom of the dust storage cavity 300.

[0062] The dust cup structure provided by the embodiment of the application comprises a first cup body 100, a second cup body 200, a dust storage cavity 300, a cyclone barrel 400, a separation cavity 500 and a baffle 600. The first cup body 100 comprises an air inlet 110 and an air outlet 120. The second cup body 200 comprises a dust discharge port 210. The cyclone barrel 400 comprises an air outlet cavity 410 and an air outlet 420. The first cup body 100 and the second cup body 200 are arranged to jointly define the dust storage cavity 300, so that the dust storage cavity 300 collects separated dust and other solids. The second cup body 200 and the cyclone barrel 400 are arranged to jointly define the separation cavity 500, so that fluid is subjected to centrifugal separation in the separation cavity 500. The air inlet 110 is arranged to allow fluid to enter the dust cup structure. The air outlet cavity 410 and the air outlet 420 are arranged to allow fluid to flow after being subjected to centrifugal separation. The air outlet 120 is arranged to allow separated fluid to be discharged from the dust cup structure. The dust discharge port 210 is arranged to communicate the dust storage cavity 300 and the separation cavity 500, so that dust and other solids subjected to centrifugal separation in the separation cavity 500 enter the dust storage cavity 300 to be deposited. The baffle 600 is arranged to block the dust and other solids that have been deposited at the bottom of the dust storage cavity 300 from flowing back under the influence of air flow. The end of the baffle 600 away from the second cup body 200 is spaced apart from the bottom wall of the first cup body 100 away from the air outlet 120 by a first spacing T1, and T1≤25mm. Thus, the baffle 600 can effectively block the dust and other solids from moving towards the dust discharge port 210, and the first spacing can allow air flow to pass smoothly. Therefore, the dust cup structure provided by the embodiment of the application has good dust collection effect.

[0063] With reference to Figure 2 With reference to Figure 4 In a possible implementation, the dust storage cavity 300 comprises a first dust storage cavity 310 and a second dust storage cavity 320 that are in communication with each other. The first dust storage cavity 310 is arranged along the radial direction of the cyclone barrel 400 relative to the separation cavity 500. The second dust storage cavity 320 is arranged along the axial direction of the cyclone barrel 400 relative to the separation cavity 500. The second dust storage cavity 320 is located at the bottom of the separation cavity 500 away from the air outlet 120. The baffle 600 is arranged between the first dust storage cavity 310 and the second dust storage cavity 320.

[0064] For example, in Figure 2The first cup body 100 and the second cup body 200 share a part of the side wall, the cyclone barrel 400 and the second cup body 200 are arranged in a nested manner, the cyclone barrel 400 and the second cup body 200 share a bottom wall, the outer wall of the second cup body 200 and the inner wall of the first cup body 100 form a dust storage cavity 300, the dust storage cavity 300 includes a first dust storage cavity 310 located at the side of the second cup body 200 and a second dust storage cavity 320 located at the bottom of the second cup body 200, the first dust storage cavity 310 and the second dust storage cavity 320 are used to store separated solid particles such as dust, the outer wall of the cyclone barrel 400 and the inner wall of the second cup body 200 form a separation cavity 500, so that the mixed fluid is subjected to primary centrifugal separation in the separation cavity 500, the common side wall of the first cup body 100 and the second cup body 200 has an air inlet 110, the side wall of the second cup body 200 has a dust discharge port 210 to communicate the separation cavity 500 and the first dust storage cavity 310, the inner wall of the cyclone barrel 400 forms an air outlet cavity 410 to allow the primary separated fluid to enter the air outlet cavity 410, and one end of the cyclone barrel 400 is open to form an air outlet 420 to communicate the air outlet cavity 410 and the air outlet 120.

[0065] In this way, when dust and other solids are deposited at the bottom of the second dust storage cavity 320, the baffle 600 arranged between the first dust storage cavity 310 and the second dust storage cavity 320 can effectively prevent the dust and other solids deposited in the second dust storage cavity 320 from moving to the first dust storage cavity 310, thereby avoiding the backflow of dust and other solids to the separation cavity 500 through the dust discharge port 210, and improving the dust collection effect of the dust storage cavity 300.

[0066] In some embodiments, the baffle 600 extends along the axial direction of the cyclone barrel 400. That is, in the height direction of the dust cup structure, the extension direction of the baffle 600 is consistent with the axial direction of the cyclone barrel 400, and in the circumferential direction of the dust cup structure, the extension direction of the baffle 600 is consistent with the circumferential direction of the second cup body 200. In this way, the baffle 600 and the side wall of the second cup body 200 can be integrally formed during processing, thereby simplifying the processing process, and relative to the inclination of the baffle 600 towards the outside of the dust cup structure, the extension of the baffle 600 along the axial direction of the cyclone barrel 400 can improve the blocking effect of the baffle 600 on dust.

[0067] Referring to Figure 2 As shown, in a possible implementation, the cyclone barrel 400 includes a filter screen 430, and the filter screen 430 is arranged at least on the peripheral wall of the cyclone barrel 400 to communicate the separation cavity 500 and the air outlet cavity 410.

[0068] In this way, when the fluid is centrifugally separated in the separation chamber 500, the dust and other large-particle solids in the fluid can be separated out, and the fluid after centrifugal separation can pass through the filter screen 430 and then enter the air outlet chamber 410, and then flow along the air outlet 420 and the air outlet 120 in turn.

[0069] Referring to Figure 4 As shown in the specific implementation, the filter screen 430 includes a first filter screen 431 and a second filter screen 432. The first filter screen 431 is arranged on the side wall of the cyclone barrel 400 to communicate the separation chamber 500 and the dust storage chamber 300. The second filter screen 432 is arranged on the bottom wall of the cyclone barrel 400 facing away from the air outlet 120 to communicate the dust storage chamber 300 and the air outlet chamber 410.

[0070] In this way, when the fluid is centrifugally separated in the separation chamber 500, the dust and other large-particle solids in the fluid can be separated out, and the fluid after centrifugal separation can pass through the filter screen 430 and then enter the air outlet chamber 410, and then flow along the air outlet 420 and the air outlet 120 in turn.

[0071] At the same time, another part of the airflow flows along the dust discharge port 210, the first dust storage chamber 310, the second dust storage chamber 320, the air outlet chamber 410, the air outlet 420 and the air outlet 120 under the action of suction, and in this process, the airflow can drive the separated dust and other solids from the dust discharge port 210 into the first dust storage chamber 310, and the airflow can drive the dust and other solids to flow to the bottom of the first dust storage chamber 310 and the second dust storage chamber 320, and then make the dust and other solids deposit at the bottom of the second dust storage chamber 320, thereby improving the dust collection effect of the dust cup structure. Moreover, when the dust and other solids deposit at the bottom of the second dust storage chamber 320, the baffle 600 can effectively prevent the backflow of the dust and other solids, thereby improving the dust collection effect of the dust cup structure.

[0072] In one possible implementation, the ventilation area of the first filter screen 431 is greater than the ventilation area of the second filter screen 432.

[0073] It should be noted that, relatively speaking, the path of the airflow flowing in the air inlet 110, the separation cavity 500, the air outlet cavity 410, the air outlet 420, and the air outlet 120 in sequence is shorter, and the path of the airflow flowing in the air inlet 110, the separation cavity 500, the dust discharging port 210, the dust storage cavity 300, the second dust storage cavity 320, the air outlet cavity 410, the air outlet 420, and the air outlet 120 in sequence is longer, and therefore, considering the suction force of the cleaning device, most of the airflow can flow in the air inlet 110, the separation cavity 500, the air outlet cavity 410, the air outlet 420, and the air outlet 120, thereby avoiding reducing the suction force of the dust cup structure, and a small part of the airflow flows in the air inlet 110, the separation cavity 500, the dust discharging port 210, the dust storage cavity 300, the second dust storage cavity 320, the air outlet cavity 410, the air outlet 420, and the air outlet 120, thereby improving the dust collection effect of the dust storage cavity 300.

[0074] Referring to Figure 2 With Figure 5 As shown in FIG. 7, in a possible implementation, the dust cup structure further includes an air guide assembly 700, which is arranged in the air outlet 420. The air guide assembly 700 includes a flow guide piece 710 and a plurality of support ribs 720. The plurality of support ribs 720 are arranged at intervals along the circumference of the flow guide piece 710. The support ribs 720 are connected between the outer circumferential wall of the flow guide piece 710 and the inner circumferential wall of the air outlet 420. The flow guide piece 710, the support ribs 720, and the air outlet 420 define an air guide channel therebetween.

[0075] In this way, the flow guide piece 710 can be connected to the first cup body 100 by arranging the support ribs 720. The flow guide piece 710, the air outlet 420, and the plurality of support ribs 720 define a plurality of air guide channels therebetween. When the airflow passes through the plurality of air guide channels, the airflow can be dispersed, thereby reducing the flow speed of the airflow. In addition, the flow guide piece 710 can change the flow direction of the airflow, so that the airflow can uniformly pass through each region of the first filter assembly 800 at a lower flow rate when flowing to the downstream first filter assembly 800, thereby improving the filtering effect of the first filter assembly 800.

[0076] Referring to Figure 5 As shown in FIG. 7, in some embodiments, the side of the flow guide piece 710 away from the air outlet 120 has a flow guide curved surface 711 for guiding the fluid to flow in the radial direction of the cyclone drum 400.

[0077] It can be understood that in the process of airflow flowing from the air outlet cavity 410 to the first air outlet 420, the flow direction of the airflow is mainly along the axial direction of the cyclone barrel 400, and the flow guide curved surface 711 can guide the flow direction of the airflow to gradually change from the axial direction of the cyclone barrel 400 to each radial direction of the cyclone barrel 400. Compared with a flat surface, the curved surface has a better flow guiding effect, and then the airflow is guided to flow along each radial direction of the cyclone barrel 400 through the flow guide curved surface 711, so as to disperse the flow direction of the airflow and uniformly reduce the flow rate of the airflow.

[0078] Referring to Figure 5 In specific implementation, the flow guide member 710 includes a first flow guide part 712 and a second flow guide part 713 connected to each other, the first flow guide part 712 is conical, and the end of the first flow guide part 712 close to the air outlet 120 is larger than the end of the first flow guide part 712 away from the air outlet 120. The second flow guide part 713 is connected to the end of the first flow guide part 712 close to the air outlet 120, and the second flow guide part 713 is folded towards the outside of the first flow guide part 712.

[0079] In this way, the side of the flow guide member 710 away from the air outlet 120 forms the flow guide curved surface 711, the flow guide curved surface 711 can guide the flow direction of the airflow to gradually change from the axial direction of the cyclone barrel 400 to each radial direction of the cyclone barrel 400, so as to gently change the flow direction of the airflow, and in this process, the flow guide curved surface 711 can cooperate with the air guide channel to disperse a large airflow into multiple small airflows and then flow out, thereby reducing the flow rate of the airflow.

[0080] Referring to Figure 1 , Figure 2 With Figure 4 In a possible implementation, the dust cup structure further includes a first filter assembly 800 and a second filter assembly 900, the first cup body 100 further has a mounting cavity 130, the mounting cavity 130 and the dust storage cavity 300 are separated by a partition plate 140, the dust storage cavity 300 and the mounting cavity 130 are located at two ends of the first cup body 100, and the air outlet 120 is located at the end of the mounting cavity 130 away from the dust storage cavity 300.

[0081] The first filter assembly 800 and the second filter assembly 900 are both arranged in the mounting cavity 130, and the first filter assembly 800 is located on the side of the second filter assembly 900 away from the air outlet 120.

[0082] In this way, the partition 140 can block the installation cavity 130 and the dust storage cavity 300 to prevent dust and other solids in the dust storage cavity 300 from entering the installation cavity 130, the first filter assembly 800 can perform secondary separation filtering on the fluid, the second filter assembly 900 can perform third separation filtering on the fluid, and then the dust cup structure is discharged from the air outlet 120. In this way, in combination with the primary centrifugal separation of the fluid in the separation cavity 500, the fluid can flow through at least three times of filtering and separation in the dust cup structure, thereby effectively improving the dust-gas separation effect of the dust cup structure, so as to prevent dust and the like from entering the main machine or to prevent dust from flowing back to the environment.

[0083] Referring to Figure 2 In some embodiments, the first filter assembly 800 and the flow guide 710 have a second spacing T2 in the axial direction of the cyclone barrel 400, and the second spacing T2 satisfies T2≥5mm.

[0084] It should be understood that if the second spacing T2 is small, the airflow is easy to concentrate and flow to some areas of the first filter assembly 800, thereby easily causing the first filter assembly 800 to be not uniform in filtering the airflow, thereby reducing the filtering efficiency of the first filter assembly 800, and when the second spacing T2 is small, the contact time of the airflow when passing through the first filter assembly 800 is also not enough, thereby reducing the filtering effect of the first filter assembly 800.

[0085] Therefore, the second spacing T2 can be greater than or equal to 5mm, thereby causing the airflow to be uniformly distributed on the first filter assembly 800 and increasing the contact time of the airflow with the first filter assembly 800, thereby improving the filtering and separation effect of the first filter assembly 800.

[0086] Referring to Figure 6 In a possible implementation, the diameter d of the cyclone barrel 400 and the diameter D of the second cup body 200 satisfy d / D≤1 / 2. And / or, the distance between the inner circumferential wall of the second cup body 200 and the outer circumferential wall of the cyclone barrel 400 is greater than or equal to 20mm.

[0087] For example, the diameter d of the cyclone barrel 400 and the diameter D of the second cup body 200 satisfy d / D≤1 / 2. For another example, the distance between the inner circumferential wall of the second cup body 200 and the outer circumferential wall of the cyclone barrel 400 is greater than or equal to 20mm. For another example, the diameter d of the cyclone barrel 400 and the diameter D of the second cup body 200 satisfy d / D≤1 / 2, and the distance between the inner circumferential wall of the second cup body 200 and the outer circumferential wall of the cyclone barrel 400 is greater than or equal to 20mm.

[0088] In this way, when the diameter d of the cyclone cylinder 400 and the diameter D of the second cup body 200 satisfy d / D≤1 / 2, the rotation radius of the fluid can be increased, and the centrifugal force of the fluid can be increased, thereby improving the centrifugal separation effect of the separation cavity 500. When the distance between the inner circumferential wall of the second cup body 200 and the outer circumferential wall of the cyclone cylinder 400 is greater than or equal to 20mm, the distance between the cyclone cylinder 400 and the second cup body 200 in the radial direction can be increased, and the fluid can rotate away from the cyclone cylinder 400 under the action of inertia after entering the separation cavity 500, thereby avoiding solid blockage of the filter screen 430.
