Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a dust cup structure and a cleaning device. Background Technology

[0002] As living standards continue to improve, people have higher and higher requirements for their living environment. Household cleaning equipment, such as vacuum cleaners and floor scrubbers, are gradually becoming an indispensable part of daily life.

[0003] In related technologies, cleaning equipment may include a device body and a dust cup disposed on the device body, with a filter (such as a filter screen) installed inside the dust cup. When the cleaning equipment is operating, the device body can generate negative pressure and draw air in through the air inlet of the dust cup, simultaneously bringing dust, hair, and other debris into the dust cup to achieve the cleaning of the surface to be cleaned. Air can sequentially enter the device body through the ventilation holes on the filter and the air outlet of the dust cup, while dust, hair, and other debris are blocked by the filter inside the dust cup.

[0004] However, during use, hair and other debris may clog the vents on the filter, causing poor airflow. Utility Model Content

[0005] This application provides a dust cup structure and a cleaning device to solve the problem of hair and other debris clogging the ventilation holes on the filter, causing poor airflow.

[0006] Firstly, the dust cup structure provided in this application includes:

[0007] The dust cup body has a dust collection chamber and at least two cyclone separation chambers inside. The cyclone separation chambers are connected to the dust collection chambers. An air outlet is provided on the top of the dust cup body.

[0008] At least two separators are installed in the cyclone separation chamber, with the separators positioned close to the air outlet, and the outlet of each separator is connected to the air outlet.

[0009] The separator is configured to trap debris within the cyclone separator as the airflow is guided along its circumference.

[0010] In this way, the cyclone separation chamber can guide the airflow carrying impurities along the circumference of the separator. Under the action of centrifugal force, the impurities move in a circular motion along the inner wall of the cyclone separation chamber. This prevents hair and other impurities from clogging the ventilation holes on the separator, allowing the airflow to pass through the separator more smoothly, thereby improving the dust-gas separation efficiency. Furthermore, the airflow carrying impurities is divided into multiple branches and distributed to multiple cyclone separation chambers. The amount of impurities processed by each separator in each cyclone separation chamber is reduced, thereby improving the dust-gas separation efficiency.

[0011] In one possible implementation, the dust cup structure provided in this application has the axis of the separator perpendicular to the vertical direction.

[0012] Thus, after the airflow carrying impurities enters the cyclone separator chamber, it rotates along the circumference of the separator under the guidance of the cyclone separator chamber, and this rotational motion moves in the horizontal direction to form a transverse rotating airflow. As a result, the impurities move in a transverse circular motion along the inner wall of the cyclone separator chamber under the action of centrifugal force, so that the airflow and impurities are separated more thoroughly and the dust-gas separation efficiency is improved.

[0013] In one possible implementation, the dust cup structure provided in this application has a cyclone separation chamber with a dust throwing port, the cyclone separation chamber is connected to the dust collection chamber through the dust throwing port, and the axis of the dust throwing port is perpendicular to the vertical direction.

[0014] In this way, under the action of centrifugal force, the debris makes a transverse circular motion along the inner wall of the cyclone separation chamber, and is thrown out of the cyclone separation chamber through the ash throwing port to enter the dust collection chamber.

[0015] In one possible implementation, the dust cup structure provided in this application further includes a filter element disposed on the dust cup body and covering the air outlet.

[0016] In this way, the filter intercepts the dust entering the air outlet, preventing small debris such as dust from passing through the separator's ventilation holes and entering the suction component of the cleaning equipment through the air outlet, which could damage the suction component.

[0017] In one possible implementation, the dust cup structure provided in this application further includes a separating component disposed within the dust collection chamber, the separating component forming at least two cyclone separation chambers.

[0018] Thus, two cyclone separation chambers are formed in the dust collection chamber by the separation component. The separation chambers are set on the separation component to guide the airflow along the circumference of the separator.

[0019] In one possible implementation, the dust cup structure provided in this application includes the following separating components:

[0020] The support component is located inside the dust collection chamber and is connected to the inner wall of the dust cup body.

[0021] At least two guide members are provided, each guide member is spaced apart on the support member and located inside the dust collection chamber, and the guide members and the support member form a cyclone separation chamber;

[0022] The guide is configured to guide the airflow along the circumference of the separator.

[0023] Thus, the support component connects to the inner wall of the dust cup body to provide support and ensure the stability of the separator assembly installation. Guide components are mounted on the support component to collectively form the cyclone separation chamber.

[0024] In one possible implementation, the dust cup structure provided in this application includes a guide component comprising:

[0025] A connecting part is connected to a support member, and a separator is disposed on the connecting part;

[0026] The arc-shaped part is connected to the connecting part and the support member respectively, and the arc-shaped part is arranged around the periphery of the separator.

[0027] Thus, the airflow carrying impurities enters the cyclone separator tangentially and, guided by the arc-shaped section, forms an airflow rotating around the outer circumference of the separator. Under the action of centrifugal force, the impurities press against the arc-shaped section and move along its extension direction until they reach the edge of the arc-shaped section, whereupon they are thrown out of the cyclone separator and enter the dust collection chamber.

[0028] In one possible implementation, the dust cup structure provided in this application further includes a baffle member in the separation component. The baffle member connects to each connecting part, and the baffle member and each connecting part together form an air guide channel. The outlet of each separator is connected to the air guide channel.

[0029] The support is equipped with ventilation holes, and the air guide channel is connected to the air outlet through the ventilation holes.

[0030] In this way, the enclosure and the connecting parts together form an air guide channel, which guides the airflow to the air outlet on the dust cup body. After the airflow enters the separator, it can sequentially pass through the separator outlet, the air guide channel, and the vent on the support to enter the air outlet on the dust cup body.

[0031] In one possible implementation, the dust cup structure provided in this application further includes a rotating guide, which is disposed on the dust cup body. The dust cup body is provided with an air inlet, and each cyclone separation chamber is connected to the air inlet. Part of the rotating guide extends into the space between the air inlet and the cyclone separation chamber.

[0032] The rotating guide is configured to direct some of the debris into the cyclone separation chamber.

[0033] Thus, under negative pressure, the airflow entering the inlet can be divided into at least two branches and enter the corresponding cyclone separation chambers. Part of the rotating guide extends between the inlet and the cyclone separation chamber. The rotating guide can rotate to guide long strips of debris such as hair and paper strips into one of the cyclone separation chambers, preventing these long strips of debris from being affected by the forces of multiple branches and blocking the inlet, thus affecting the dust collection efficiency of the dust cup structure.

[0034] In one possible implementation, the dust cup structure provided in this application includes a rotating guide comprising:

[0035] A rotary drive component is mounted on the dust cup body.

[0036] The guide component is connected to the rotary drive component and extends between the air inlet and the cyclone separation chamber.

[0037] The guide is configured to rotate under the action of the rotary drive to guide some of the debris into the cyclone separation chamber.

[0038] In this way, the rotary drive can drive the guide to rotate, so that long strips of debris such as hair and paper strips can be guided into one of the cyclone separation chambers by the rotation of the guide, thus avoiding blockage.

[0039] In one possible implementation, the dust cup structure provided in this application has the axis of the guide perpendicular to the axis of the separator.

[0040] In this way, the guide rotates to direct long, thin debris such as hair and paper strips into one of the cyclone separation chambers.

[0041] In one possible implementation, the dust cup structure provided in this application has at least one annular guide groove on the outer side of the guide member;

[0042] And / or, the guide is a conical part.

[0043] In this way, when long, thin objects such as hair and paper strips come into contact with the guide, they can be stuck in the annular guide groove, thus preventing them from sliding off the guide due to gravity and blocking the air inlet.

[0044] In one possible implementation, the dust cup structure provided in this application further includes a connector for the rotating guide, the connector being connected to the rotating drive, and a first plug-in portion being provided at the end of the connector away from the rotating drive.

[0045] The guide is provided with a second plug-in part, and the first plug-in part and the second plug-in part are plugged in accordingly.

[0046] Thus, the connector is used to connect the rotary drive and the guide. The connector is disposed on the rotary drive, and the first plug-in part on the connector is plugged into the second plug-in part on the guide to realize the detachable connection between the connector and the guide, so as to facilitate replacement and maintenance.

[0047] In one possible implementation, the dust cup structure provided in this application has at least one first connecting part on the rotating drive component and at least one second connecting part in the dust cup body, with the first connecting part and the second connecting part correspondingly connected.

[0048] And / or, the rotary drive is a motor or an impeller.

[0049] Thus, the rotating drive component is fixed to the dust cup body by the corresponding connection between the first connecting part and the second connecting part.

[0050] In one possible implementation, the dust cup structure provided in this application has a distance of 30mm to 50mm between the guide and the air inlet.

[0051] This ensures that the distance between the guide and the air inlet is within a suitable range, preventing them from being too close and thus obstructing debris from entering the air inlet and causing blockage. It also prevents them from being too far apart, which would prevent the guide from effectively guiding long, thin debris such as hair and paper strips.

[0052] Secondly, the cleaning equipment provided in this application includes a device body and any of the dust cup structures mentioned above, with the device body connected to the dust cup structure.

For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components.

[0074] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0075] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0076] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0077] In related technologies, cleaning equipment may include a device body and a dust cup disposed on the device body, with a filter element (such as a filter screen) installed inside the dust cup. When the cleaning equipment is operating, the device body can generate negative pressure and draw air in through the air inlet of the dust cup, simultaneously bringing dust, hair, and other debris into the dust cup to achieve the cleaning of the surface to be cleaned. Air can sequentially enter the device body through the ventilation holes on the filter element and the air outlet of the dust cup, while dust, hair, and other debris are blocked by the filter element inside the dust cup.

[0078] However, during use, hair and other debris may clog the vents on the filter, causing poor airflow.

[0079] In view of the above problems, this application provides a dust cup structure and a cleaning device. The dust cup structure includes a dust cup body and at least two separators. The dust cup body has a dust collection chamber and at least two cyclone separation chambers, which are connected to the dust collection chamber. An air outlet is provided at the top of the dust cup body. The separators are correspondingly disposed within the cyclone separation chambers, positioned close to the air outlet, and each separator's outlet is connected to the air outlet. The separators are configured to block debris within the cyclone separation chambers as the airflow is guided to move circumferentially within them. The cyclone separation chambers can guide the airflow carrying debris to move circumferentially along the separators. Under the action of centrifugal force, the debris moves in a circular motion along the inner wall of the cyclone separation chambers. This prevents debris such as hair from blocking the ventilation holes on the separators, allowing the airflow to pass through the separators more smoothly, thereby improving dust-air separation efficiency. Furthermore, the airflow containing impurities is divided into multiple branches and distributed to multiple cyclone separation chambers. The amount of impurities processed by each separator in each cyclone separation chamber is reduced, thereby improving the dust-gas separation efficiency.

[0080] The following describes in detail the specific implementation of the dust cup structure and cleaning equipment provided in the embodiments of this application, with reference to the accompanying drawings.

[0081] Reference Figures 1 to 11 As shown, the dust cup structure provided in this application includes a dust cup body 100 and at least two separators 200.

[0082] The dust cup body 100 has a dust collection chamber 101 and at least two cyclone separation chambers 102 inside, which are connected to the dust collection chamber 101. An air outlet 103 is provided at the top of the dust cup body 100. Separators 200 are correspondingly disposed within the cyclone separation chambers 102, positioned close to the air outlets 103, and the outlets of each separator 200 are connected to the air outlets 103. The separators 200 are configured to block debris within the cyclone separation chambers 102 as the airflow is guided to move circumferentially within them.

[0083] It is understood that the dust cup structure provided in this application embodiment can be used in a cleaning device, which can be a vacuum cleaner. The cleaning device has a suction component, which is connected to the air outlet 103 on the dust cup body 100. When the cleaning device is working, the suction component generates suction force to draw debris from the surface to be cleaned into the dust collection chamber 101 of the dust cup body 100.

[0084] Reference Figure 3 and Figure 4 As shown, the top of the dust collection chamber 101 has at least two cyclone separation chambers 102, and a separator 200 is correspondingly arranged in each cyclone separation chamber 102. Each separator 200 has at least one ventilation hole and can filter the airflow. (Refer to...) Figures 5 to 8 As shown, the arrows indicate the direction of airflow. The airflow sequentially enters the suction assembly through the ventilation holes of the separator 200, the outlet of the separator 200, and the air outlet 103. Debris is blocked by the separator 200 within the cyclone separation chamber 102. The separator 200 can be a conical structure.

[0085] To prevent debris from clogging the ventilation holes on separator 200 and causing airflow obstruction. (Refer to...) Figures 3 to 8 As shown, the cyclone separation chamber 102 can guide the airflow carrying debris to move circumferentially along the separator 200. Under the action of centrifugal force, the debris moves in a circle along the inner wall of the cyclone separation chamber 102 and enters the dust collection chamber 101 under the action of its own gravity, and is deposited downward to the bottom of the dust collection chamber 101. Meanwhile, the clean airflow enters the air outlet 103 through the separator 200. This can prevent hair and other debris from blocking the ventilation holes on the separator 200, so that the airflow can pass through the separator 200 more smoothly, thereby improving the dust and gas separation efficiency.

[0086] Furthermore, the separators 200 are positioned close to the air outlet 103, and the outlets of each separator 200 are connected to the air outlet 103. This shortens the distance between the outlets of each separator 200 and the air outlet 103, thereby shortening the airflow path, reducing friction loss, and increasing the airflow rate.

[0087] Specifically, refer to Figure 3 As shown, the cyclone separation chamber 102 is located at the top of the dust collection chamber 101, and the air outlet 103 is located at the top of the dust cup body 100, so that the separator 200 is located close to the air outlet 103.

[0088] The system includes at least two cyclone separation chambers 102 and at least two separators 200. This divides the airflow containing impurities into multiple branches and distributes them to the multiple cyclone separation chambers 102. Each separator 200 within each cyclone separation chamber 102 handles a reduced airflow and amount of impurities, thereby improving dust-air separation efficiency. Furthermore, this also reduces the load on the separators 200 and prevents clogging of the ventilation holes on the separators 200.

[0089] The dust cup structure provided in this embodiment guides the airflow carrying debris in the cyclone separation chamber 102 to move circumferentially along the separator 200. Under centrifugal force, the debris moves in a circular motion along the inner wall of the cyclone separation chamber 102. This prevents debris such as hair from clogging the ventilation holes on the separator 200, allowing the airflow to pass through the separator 200 more smoothly, thereby improving dust-gas separation efficiency. Furthermore, the airflow carrying debris is divided into multiple branches and distributed to multiple cyclone separation chambers 102, reducing the amount of debris processed by each separator 200 within each cyclone separation chamber 102, thus improving dust-gas separation efficiency.

[0090] Among them, reference Figure 3 As shown, the outer surface of the separator 200 is an arc-shaped surface. The smooth outer surface of the arc-shaped surface makes it difficult for hair and other debris in the airflow to get tangled on the separator 200, thus avoiding blockage. For example, the separator 200 can be conical, hemispherical, semi-ellipsoidal, or other shapes, and this application embodiment does not impose any restrictions on this.

[0091] Reference Figure 3 and Figure 9 As shown, in some embodiments, the axis of the separator 200 is perpendicular to the vertical direction.

[0092] Among them, reference Figures 3 to 5 As shown, the axis of the cyclone separation chamber 102 is perpendicular to the vertical direction.

[0093] In this way, after the airflow carrying impurities enters the cyclone separation chamber 102, it rotates along the circumference of the separator 200 under the guidance of the cyclone separation chamber 102, and this rotational motion moves in the horizontal direction to form a transverse rotating airflow. As a result, the impurities move in a transverse circular motion along the inner wall of the cyclone separation chamber 102 under the action of centrifugal force, so that the airflow and impurities are separated more thoroughly and the dust-gas separation efficiency is improved.

[0094] Reference Figure 3 , Figure 4 , Figure 5 and Figure 9 As shown, in some embodiments, the cyclone separation chamber 102 has a dust throwing port 1021, and the cyclone separation chamber 102 is connected to the dust collection chamber 101 through the dust throwing port 1021. The axis of the dust throwing port 1021 is perpendicular to the vertical direction.

[0095] In this way, under the action of centrifugal force, the debris makes a transverse circular motion along the inner wall of the cyclone separation chamber 102, and is thrown out of the cyclone separation chamber 102 through the ash throwing port 1021 to enter the dust collection chamber 101.

[0096] Reference Figure 3 , Figure 4 and Figure 9 As shown, in some embodiments, there are two cyclone separation chambers 102 and two separators 200. The two cyclone separation chambers 102 are arranged opposite to each other, and the separators 200 are correspondingly arranged in the cyclone separation chambers 102. The two separators 200 have a common first axis, and the two cyclone separation chambers 102 have a common second axis. Both the first axis and the second axis extend in the horizontal direction (i.e., perpendicular to the vertical direction).

[0097] Furthermore, the first axis coincides with the second axis.

[0098] Reference Figure 3 and Figure 4 As shown, in some embodiments, the dust cup structure provided in this application further includes a filter element 300, which is disposed on the dust cup body 100 and covers the air outlet 103.

[0099] In this way, the filter element 300 intercepts the dust entering the air outlet 103, so as to prevent small debris such as dust from passing through the ventilation holes of the separator 200 and entering the suction component of the cleaning equipment through the air outlet 103, which would damage the suction component.

[0100] For example, the filter element 300 can be HEPA, filter cotton, filter screen, etc., and the embodiments of this application do not impose too many restrictions on it.

[0101] Reference Figure 3 and Figure 4 As shown, in some embodiments, the dust cup structure provided in this application further includes a separator 400, which is disposed in the dust collection chamber 101 and forms at least two cyclone separation chambers 102.

[0102] Thus, two cyclone separation chambers 102 are formed in the dust collection chamber 101 by the separation component 400. The separation chambers are arranged on the separation component 400 to guide the airflow to flow along the circumference of the separator 200.

[0103] Among them, reference Figure 3 and Figure 4 As shown, the separator 400 is located at the top inside the dust collection chamber 101 and close to the air outlet 103. This shortens the distance between the outlet of each separator 200 and the air outlet 103, thereby shortening the airflow path, increasing the airflow rate, and further improving the dust-gas separation efficiency.

[0104] Reference Figure 3 and Figure 4 As shown, in some embodiments, the separator assembly 400 includes a support member 410 and at least two guide members 420. The support member 410 is disposed within the dust collection chamber 101 and is connected to the inner wall of the dust cup body 100. Each guide member 420 is spaced apart on the support member 410 and located within the dust collection chamber 101, forming a cyclone separation chamber 102 with the support member 410. The guide members 420 are configured to guide airflow along the circumferential direction of the separator 200.

[0105] In this way, the support member 410 is connected to the inner wall of the dust cup body 100 to provide support and ensure the stability of the separator assembly 400 during installation. The guide member 420 is disposed on the support member 410 to jointly form the cyclone separation chamber 102.

[0106] Among them, reference Figure 3 and Figure 4 As shown, the guide member 420 can be used to install the separator 200. The guide member 420 and the support member 410 form an arc-shaped cyclone separation chamber 102. The air inlet direction is tangent to the cyclone separation chamber 102. In this way, under the action of the cyclone separation chamber 102, the airflow is guided to form an airflow that rotates around the outer periphery of the separator 200, thereby generating centrifugal force and preventing debris from entering the ventilation holes of the separator 200 with the airflow and causing blockage.

[0107] It is understood that there are at least two guide members 420, and the number of guide members 420 can be two or more. This application embodiment does not impose any restrictions on this.

[0108] For example, refer to Figure 3 and Figure 4 As shown, the support member 410 can be integrally formed with the inner wall of the dust cup body 100 to ensure the stability of the two structures.

[0109] Reference Figures 3 to 8 As shown, in some embodiments, the guide 420 includes a connecting portion 421 and an arcuate portion 422. The connecting portion 421 is connected to the support member 410, the separator 200 is disposed on the connecting portion 421, and the arcuate portion 422 is connected to both the connecting portion 421 and the support member 410, and the arcuate portion 422 is disposed around the periphery of the separator 200.

[0110] The support member 410, the connecting part 421 and the arc-shaped part 422 together form the cyclone separation chamber 102.

[0111] Thus, the connecting part 421 is used to install the separator 200, and the arc-shaped part 422 is arranged around the periphery of the separator 200. After the airflow carrying impurities enters the cyclone separation chamber 102 tangentially, refer to... Figures 5 to 8 As shown, guided by the arc-shaped portion 422, an airflow is formed that rotates around the outer periphery of the separator 200. Under the action of centrifugal force, debris abuts against the arc-shaped portion 422 and moves along the extension direction of the arc-shaped portion 422 until it reaches the edge of the arc-shaped portion 422, thereby being thrown out of the cyclone separation chamber 102 and entering the dust collection chamber 101.

[0112] Reference Figure 3 and Figure 4 As shown, in some embodiments, the separator assembly 400 further includes a baffle 430, which connects to each connecting portion 421. The baffle 430 and each connecting portion 421 together form an air guide channel 431, and the outlet of each separator 200 is connected to the air guide channel 431. The support member 410 is provided with a vent 411, and the air guide channel 431 is connected to the air outlet 103 through the vent 411.

[0113] In this way, the enclosure 430 and each connecting part 421 together form an air guide channel 431, which guides the airflow to the air outlet 103 on the dust cup body 100. After the airflow enters the separator 200, it can sequentially enter the air outlet 103 on the dust cup body 100 through the outlet of the separator 200, the air guide channel 431, and the vent 411 on the support member 410.

[0114] Specifically, refer to Figure 4 and Figure 5 As shown in the figure, the arrows indicate the direction of airflow. After the airflow carrying debris enters the cyclone separation chamber 102, the debris is blocked by the separator 200 inside the cyclone separation chamber 102. The airflow enters the separator 200 through the ventilation holes on the separation chamber, and then enters the air outlet 103 on the dust cup body 100 through the outlet of the separator 200, the air guide channel 431 and the air vent 411 on the support member 410 in sequence. Finally, it enters the suction assembly of the cleaning equipment through the air outlet 103 on the dust cup body 100.

[0115] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the dust cup structure provided in this application further includes a rotating guide 500, which is disposed on the dust cup body 100. The dust cup body 100 is provided with an air inlet 104, and each cyclone separation chamber 102 is connected to the air inlet 104. Part of the rotating guide 500 extends between the air inlet 104 and the cyclone separation chamber 102. The rotating guide 500 is configured to guide some debris into the cyclone separation chamber 102.

[0116] In this way, after the airflow enters the air inlet 104 under negative pressure, it can be divided into at least two branches and enter the corresponding cyclone separation chamber 102. Part of the rotating guide 500 extends between the air inlet 104 and the cyclone separation chamber 102. The rotating guide 500 can rotate to guide long strips of debris such as hair and paper strips into one of the cyclone separation chambers 102, so as to avoid the long strips of debris such as hair and paper strips being affected by the force of multiple branches and blocking the air inlet 104, thus affecting the dust collection efficiency of the dust cup structure.

[0117] Specifically, refer to Figure 3 , Figure 4 and Figure 9 As shown, there are two guide members 420, which are arranged opposite each other to form two symmetrical cyclone separation chambers 102. The two cyclone separation chambers 102 are located on both sides of the air inlet 104, and the inlet of each cyclone separation chamber 102 is tangential to the air inlet 104 so that the branch of the airflow enters along the tangential direction of the cyclone separation chamber 102. The two separators 200 and the two cyclone separation chambers 102 are symmetrically arranged. The suction force of the two cyclone separation chambers 102 for long strips of debris such as hair and paper strips is equal. By placing part of the cyclone guide member 520 between the air inlet 104 and the inlet of the two cyclone separation chambers 102, the long strips of debris such as hair and paper strips are guided by the cyclone guide member 520 into one of the cyclone separation chambers 102, so as to avoid them blocking the air inlet 104 and the inlet of the two cyclone separation chambers 102.

[0118] In other embodiments, the two separators 200 are asymmetrically arranged (i.e., the two separators 200 are of different sizes), and the two cyclone separation chambers 102 are asymmetrically arranged (i.e., the two cyclone separation chambers 102 are of different sizes, the two ash throwing ports 1021 are of different sizes, the two arc-shaped portions 422 have different curvatures, etc.).

[0119] In this way, the two cyclone separation chambers 102 have different suction forces for long strips of debris such as hair and paper strips. Long strips of debris such as hair and paper strips can directly enter the cyclone separation chamber 102 with stronger suction force, so as to avoid them blocking the air inlet 104 and the inlet of the two cyclone separation chambers 102. Therefore, there is no need to set up a rotating guide 500, and the overall structure is simpler and more compact.

[0120] Reference Figure 3 , Figure 10 and Figure 11As shown, the rotating guide 500 includes a rotating drive 510 and a guide 520. The rotating drive 510 is disposed on the dust cup body 100, and the guide 520 is connected to the rotating drive 510, extending between the air inlet 104 and the cyclone separation chamber 102. The guide 520 is configured to rotate under the action of the rotating drive 510 to guide some debris into the cyclone separation chamber 102.

[0121] In this way, the rotary drive 510 can drive the guide 520 to rotate, so that the rotation of the guide 520 can guide long strips of debris such as hair and paper strips into one of the cyclone separation chambers 102, thus avoiding blockage.

[0122] The guide 520 can be in the shape of a cone, hemisphere, or semi-ellipsoid, so that long strips of debris such as hair and paper strips are not easily tangled on the guide 520, thus avoiding blockage.

[0123] For example, the rotary drive 510 can be electrically driven, such as a rotary motor, to drive the guide 520 to rotate, thereby improving efficiency. The rotary drive 510 can also be an air guide structure with blades, which is correspondingly arranged with the air outlet 103. When the airflow passes through the air outlet 103, it drives the rotary drive 510 to rotate, thus making the overall structure simpler and the cost lower.

[0124] Reference Figure 3 , Figure 4 and Figure 9 As shown, in some embodiments, the axis of the guide 520 is perpendicular to the axis of the separator 200.

[0125] In this way, the guide 520 rotates to guide long, strip-shaped debris such as hair and paper into one of the cyclone separation chambers 102.

[0126] Specifically, refer to Figure 3 and Figure 4 As shown, the axis of the guide 520 is parallel to the vertical direction, and the axis of the separator 200 is perpendicular to the vertical direction. The guide 520 is located between the two cyclone separation chambers 102 and between the two separators 200, making the overall structure more compact.

[0127] Reference Figure 11 As shown, in some embodiments, at least one annular guide groove 521 is provided on the outer side of the guide 520.

[0128] In this way, when long, thin objects such as hair and paper strips come into contact with the guide 520, they can be stuck in the annular guide groove 521, so as to prevent long, thin objects such as hair and paper strips from sliding off the guide 520 due to gravity and thus blocking the air inlet 104.

[0129] Specifically, refer to Figure 11 As shown, there can be multiple annular guide grooves 521, which are spaced apart. Of course, multiple annular guide grooves 521 can also be connected end to end to form a spiral groove.

[0130] Furthermore, refer to Figure 11 As shown, the guide 520 is a conical part, which makes it difficult for long strips of debris such as hair and paper to get tangled on the guide 520, thus avoiding blockage.

[0131] Reference Figure 11 As shown, the rotating guide 500 also includes a connector 530, which is connected to the rotating drive 510. The end of the connector 530 away from the rotating drive 510 is provided with a first insertion portion 531. The guide 520 is provided with a second insertion portion 522, and the first insertion portion 531 and the second insertion portion 522 are correspondingly inserted into each other.

[0132] In this way, the connector 530 is used to connect the rotary drive 510 and the guide 520. The connector 530 is disposed on the rotary drive 510, and the first plug-in portion 531 on the connector 530 and the second plug-in portion 522 on the guide 520 are plugged in to realize the detachable connection between the connector 530 and the guide 520, so as to facilitate replacement and maintenance.

[0133] For example, at least one of the second insertion portion 522 and the second insertion portion 522 is an insertion block and the other is an insertion slot. The insertion block and the insertion slot are inserted into each other to realize the detachable connection between the connector 530 and the guide 520.

[0134] Specifically, refer to Figure 11 As shown, the first plug-in part 531 is a plug-in block, and the second plug-in part 522 is a plug-in slot.

[0135] Reference Figure 3 and Figure 10 As shown, in some embodiments, the rotary drive member 510 is provided with at least one first connecting part 511, and the dust cup body 100 is provided with at least one second connecting part 412, with the first connecting part 511 and the second connecting part 412 correspondingly connected.

[0136] In this way, the rotary drive 510 is fixed on the dust cup body 100 by the corresponding connection between the first connecting part 511 and the second connecting part 412.

[0137] It is understood that there is at least one first connecting part 511 and at least one second connecting part 412. The number of first connecting parts 511 and the number of second connecting parts 412 can both be one or more, as long as the first connecting parts 511 and the second connecting parts 412 are connected in a one-to-one correspondence. This application embodiment does not impose too many restrictions on this.

[0138] For example, the first connecting part 511 may be provided with a through hole, and the second connecting part 412 may be provided with a threaded hole. The through hole and the threaded hole are correspondingly provided, so that the bolt can be threadedly connected through the through hole and the threaded hole to connect the first connecting part 511 and the second connecting part 412. In some other embodiments, either the first connecting part 511 or the second connecting part 412 may be a snap-fit, and the other may be a matching slot, connected by a snap-fit ​​method. The embodiments of this application do not impose too many limitations on this.

[0139] Specifically, refer to Figure 10 As shown, the second connecting part 412 can be disposed on the support member 410 of the separator assembly 400 inside the dust cup body 100. The support member 410 is also provided with mounting holes. Multiple second connecting parts 412 are arranged around the periphery of the mounting holes. The guide member 520 extends through the mounting holes into the space between the air inlet 104 and the inlet of the two cyclone separation chambers 102.

[0140] Among them, reference Figure 10 As shown, the rotary drive 510 is covered on the mounting hole. A sealing element can be provided between the rotary drive 510 and the support 410 to fill the gap between the rotary drive 510 and the support 410, so as to prevent debris from entering the air outlet 103 directly through the gap between the two via the air inlet 104.

[0141] For example, the seal can be made of elastic materials such as silicone gaskets, rubber gaskets, or foam, and this application embodiment does not impose specific limitations on this.

[0142] In some embodiments, the distance between the guide 520 and the air inlet 104 is 30mm to 50mm.

[0143] This ensures that the distance between the guide 520 and the air inlet 104 is within a suitable range, preventing them from being too close and causing the guide 520 to obstruct debris from entering the air inlet 104 and causing blockage. It also prevents them from being too far apart, which would prevent the guide 520 from effectively guiding long, thin debris such as hair and paper strips.

[0144] The distance between the guide 520 and the air inlet 104 is 30mm to 50mm. For example, the distance between the two can be 30mm, 32mm, 35mm, 38mm, 40mm, 42mm, 45mm, 48mm, 50mm, etc.

[0145] Reference Figure 10 As shown, the dust cup body 100 includes a cup body portion 110 and a cover portion 120. The cover portion 120 covers the top of the cup body portion 110 to form a dust collection chamber 101. A separator assembly 400 and a rotating guide 500 are both disposed within the cup body portion 110, and an air outlet 103 is disposed on the side wall of the cup body portion 110. The air outlet 103 and a filter element 300 are both disposed on the cover portion 120.

[0146] The ventilation holes on the separator 200 are spaced apart and evenly arranged, and the total ventilation area of ​​the ventilation holes is greater than or equal to the area of ​​the air inlet 104. The diameter of the ventilation holes is 1mm to 3mm.

[0147] The cleaning equipment provided in this application includes a device body and any of the dust cup structures described above, with the device body and the dust cup structure connected together.

[0148] Since the device body adopts the dust cup structure in the above embodiments, it also has the advantages and benefits brought by the dust cup structure, which will not be elaborated further here.
