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 improve, people have higher requirements for the quality of their living environment, and household dust removal devices such as cleaning equipment (e.g., vacuum cleaners, floor scrubbers) are increasingly appearing in people's lives.

[0003] In related technologies, cleaning equipment may include a connected equipment body and a dust cup, with a separation cone installed inside the dust cup. When the cleaning equipment is operating, a negative pressure is created within the equipment body, drawing air in through the air inlet of the dust cup, simultaneously bringing dust, hair, and other debris into the dust cup. Air can then enter the equipment body sequentially through the ventilation holes on the separation cone and the air outlet of the dust cup, while dust, hair, and other debris are trapped inside the dust cup by the separation cone.

[0004] However, during use, hair and other debris may block the ventilation holes on the separation cone, causing poor airflow. Utility Model Content

[0005] This application provides a dust cup structure and a cleaning device to solve the problem in the related art where hair and other debris block the ventilation holes on the separation cone, causing poor airflow.

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

[0007] The dust cup body has a dust collection chamber inside.

[0008] The first separation cone is disposed inside the dust collection chamber;

[0009] An air guide assembly is rotatably mounted inside the dust collection chamber.

[0010] The scraper assembly is located inside the dust collection chamber and is sleeved on the outside of the first separation cone. The scraper assembly is connected to the air guide assembly.

[0011] The scraper assembly is configured to rotate relative to the first separation cone when the air guide assembly is rotated by the airflow in the dust collection chamber, so as to clean the debris on the first separation cone.

[0012] In this way, the air guide assembly can rotate under the influence of airflow, thereby driving the scraper assembly to move. The rotation effect is good and the motor can be omitted, reducing costs. The scraper assembly rotates relative to the first separation cone while adhering to the outer circumference of the first separation cone to clean the debris attached to the first separation cone, thereby preventing debris from blocking the ventilation holes and allowing airflow to pass through the first separation cone more smoothly.

[0013] In one possible implementation, the dust cup structure provided in this application further includes a mounting bracket, which is disposed inside the dust collection chamber, and the first separation cone is disposed on the mounting bracket.

[0014] In this way, the mounting bracket can play a supporting role, and the first separation cone can be positioned and installed by the mounting bracket to prevent the first separation cone from shifting due to vibration or suction during use.

[0015] In one possible implementation, the dust cup structure provided in this application has a mounting bracket that divides the dust collection chamber into a first separation chamber and a second separation chamber that are connected to each other. The scraping assembly and part of the first separation cone are disposed in the first separation chamber, and the air guide assembly is rotatably disposed on the first separation cone and located in the second separation chamber. The first separation cone is used to filter the airflow entering the second separation chamber.

[0016] The dust cup body is provided with an air inlet and an air outlet. The air inlet is connected to the first separation chamber, and the air outlet is connected to the second separation chamber.

[0017] Thus, when the suction component of the cleaning equipment is working, the airflow enters the first separation chamber through the air inlet, then enters the second separation chamber through the first separation cone, and finally enters the suction component through the air outlet. The first separation chamber can collect debris blocked by the first separation cone.

[0018] In one possible implementation, the dust cup structure provided in this application further includes a second separation cone, which is disposed in a second separation chamber and is used to filter the airflow entering the outlet.

[0019] Thus, by setting a second separation cone in the second separation chamber, a two-stage separation system is formed with the first separation cone. The first separation cone initially blocks larger debris in the first separation chamber, and the second separation cone further blocks smaller debris in the second separation chamber, thereby effectively improving the filtration effect on the airflow.

[0020] In one possible implementation, the dust cup structure provided in this application further includes a filter element disposed at the air outlet.

[0021] In this way, the filter intercepts dust entering the air outlet, preventing dust from entering the suction component of the cleaning equipment through the air outlet and causing damage to the suction component.

[0022] In one possible implementation, the dust cup structure provided in this application has a seal between the first separation cone and the mounting bracket.

[0023] In this way, the gap between the first separation cone and the mounting bracket is filled by the seal to prevent debris from entering the second separation chamber through the gap between the two from the first separation chamber.

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

[0025] A support frame is fitted onto the outside of the first separation cone and is connected to the air guide assembly;

[0026] At least one scraper is provided on the support frame and abuts against the outer periphery of the first separation cone. The scraper is used to clean debris from the first separation cone.

[0027] Thus, the support frame is fitted onto the outside of the first separation cone to support the scraper strip. Under the action of the air guide assembly, the support frame can rotate relative to the first separation cone, thereby allowing the scraper strip to clear debris from the first separation cone.

[0028] In one possible implementation, the dust cup structure provided in this application includes a support frame comprising:

[0029] The support ring is sleeved on the outside of the first separation cone;

[0030] The first connecting part passes through the first separation cone and is connected to the air guide assembly;

[0031] The scraper is positioned between the support ring and the first connecting part.

[0032] Thus, by placing the scraper between the support ring and the first connecting part, it is ensured that the scraper always abuts against the outside of the first separating cone during rotation, thereby improving cleaning efficiency and preventing the scraper from detaching from the outside of the first separating cone due to centrifugal force.

[0033] In one possible implementation, the dust cup structure provided in this application has a scraping film on the side of the scraping strip facing the first separation cone.

[0034] In this way, the scraping film elastically abuts against the outer side of the first separating cone, and its flexibility allows it to fit tightly against the outer surface of the first separating cone, thereby improving cleaning efficiency.

[0035] In one possible implementation, the dust cup structure provided in this application has the air guide assembly disposed inside the first separation cone.

[0036] Thus, the scraper assembly and the air guide assembly are respectively located on the inner and outer sides of the first separation cone. The air guide assembly, the scraper assembly and the first separation cone are integrated together, making the overall structure more compact and reducing the space occupied in the dust collection chamber.

[0037] In one possible implementation, the dust cup structure provided in this application includes an air guide component comprising:

[0038] A connector is rotatably disposed within the first separating cone and is connected to the scraper assembly.

[0039] Impeller component, the impeller component is connected to the connecting component, and the end of the impeller component away from the connecting component is rotatably connected to the dust cup body;

[0040] The impeller is configured to rotate under the influence of the airflow in the dust collection chamber, and drive the scraper assembly to rotate via the connecting parts.

[0041] Thus, the impeller rotates relative to the first separation cone under the influence of the airflow, and drives the scraper assembly to rotate through the connecting parts, thereby cleaning the debris on the outside of the first separation cone.

[0042] In one possible implementation, the dust cup structure provided in this application further includes a flow guide component, which connects the impeller component and the connecting component.

[0043] The flow guide is configured to direct airflow onto the impeller.

[0044] In this way, the airflow is concentrated by the guide and directed toward the impeller, thereby increasing the force of the airflow on the impeller and thus increasing the speed and output power of the impeller.

[0045] In one possible implementation, the dust cup structure provided in this application has a first bearing component on the first separation cone, and a connecting component is connected to the inner ring of the first bearing component;

[0046] And / or, a second bearing component is provided on the dust cup body, and the impeller component is connected to the inner ring of the second bearing component.

[0047] Thus, by incorporating a first bearing component, the rotational resistance of the connecting component is reduced. By incorporating a second bearing component, the rotational resistance of the impeller component is reduced.

[0048] In one possible implementation, the dust cup structure provided in this application has a mounting part on the first separation cone, and a mounting through hole is provided on the mounting part, through which the scraping assembly and the air guiding assembly are connected.

[0049] In this way, the scraper assembly and the air guide assembly can be connected through the mounting holes to make the overall structure more compact.

[0050] In one possible implementation, the dust cup structure provided in this application includes a first separation cone comprising:

[0051] The main body has an air guide assembly rotatably mounted on the inner side of the main body, a scraper assembly sleeved on the outer side of the main body, and a mounting part mounted on the main body.

[0052] The second connecting part is provided on the main body and is detachably connected to the mounting bracket.

[0053] In this way, the airflow entering the second separation chamber can be filtered through the main body, while debris is blocked in the first separation chamber. The second connecting part is used to fix the main body to the mounting bracket.

[0054] 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.

[0079] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0080] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. 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. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] In related technologies, cleaning equipment may include a connected equipment body and a dust cup, with a separation cone installed inside the dust cup. When the cleaning equipment is operating, a negative pressure is created within the equipment body, drawing air in through the air inlet of the dust cup, simultaneously bringing dust, hair, and other debris into the dust cup. Air can sequentially enter the equipment body through the ventilation holes on the separation cone and the air outlet of the dust cup, while dust, hair, and other debris are trapped inside the dust cup by the separation cone.

[0085] However, during use, hair and other debris may block the ventilation holes on the separation cone, causing poor airflow.

[0086] 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, a first separating cone, an air guide assembly, and a scraper assembly. The dust cup body has a dust collection chamber inside, and the first separating cone, air guide assembly, and scraper assembly are all disposed within the dust collection chamber. The air guide assembly is rotatably disposed within the dust collection chamber, and the scraper assembly is sleeved on the outside of the first separating cone, connected to the air guide assembly. The scraper assembly is configured such that, when the air guide assembly rotates under the influence of airflow within the dust collection chamber, it rotates relative to the first separating cone to clean debris from the first separating cone. Both the air guide assembly and the scraper assembly are integrated onto the first separating cone, resulting in a simple, compact, and low-cost overall structure. The air guide assembly can rotate under the influence of airflow, thereby driving the scraper assembly to move, resulting in good rotational performance and eliminating the need for a motor, thus reducing costs. The scraper assembly rotates relative to the first separating cone along its outer periphery to clean debris adhering to the first separating cone, thereby preventing debris from clogging the ventilation holes and allowing airflow to pass more smoothly through the first separating cone.

[0087] 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.

[0088] Reference Figures 1 to 13 As shown in the embodiment of this application, the dust cup structure includes a dust cup body 100, a first separation cone 200, an air guide assembly 300, and a scraper assembly 400.

[0089] The dust cup body 100 has a dust collection chamber 101 inside, and the first separating cone 200, the air guide assembly 300, and the scraper assembly 400 are all disposed inside the dust collection chamber 101. The air guide assembly 300 is rotatably disposed inside the dust collection chamber 101, and the scraper assembly 400 is sleeved on the outside of the first separating cone 200 and connected to the air guide assembly 300. The scraper assembly 400 is configured to rotate relative to the first separating cone 200 under the influence of the airflow in the dust collection chamber 101 when the air guide assembly 300 is rotated, so as to clean the debris on the first separating cone 200.

[0090] 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 that is connected to the dust collection chamber 101. When the cleaning device is working, the suction component generates a suction force to draw debris from the surface to be cleaned into the dust collection chamber 101 of the dust cup body 100.

[0091] Reference Figures 10 to 13 As shown, a first separating cone 200 is provided inside the dust collection chamber 101. The first separating cone 200 has at least one ventilation hole. The first separating cone 200 can filter the airflow. The airflow enters the suction assembly through the ventilation hole, while the debris is blocked by the first separating cone 200 inside the dust collection chamber 101. The first separating cone 200 can be a conical structure.

[0092] To prevent debris from clogging the ventilation holes on the first separation cone 200, thus hindering airflow. (Refer to...) Figure 2 , Figure 3 and Figure 10 As shown, a guide assembly 300 is rotatably mounted on the first separation cone 200, and a scraper assembly 400 is sleeved on the outer side of the first separation cone 200. The guide assembly 300 can rotate under the influence of airflow, thereby driving the scraper assembly 400 to move. The scraper assembly 400 rotates relative to the outer periphery of the first separation cone 200 to clean the debris attached to the first separation cone 200, thereby preventing debris from blocking the ventilation holes and allowing airflow to pass through the first separation cone 200 more smoothly.

[0093] Furthermore, the air guide assembly 300 is driven to rotate by airflow, eliminating the need for additional electric drive components, which simplifies the structure and reduces costs.

[0094] The dust cup structure provided in this application embodiment integrates both the air guide assembly 300 and the scraper assembly 400 onto the first separation cone 200, resulting in a simple, compact, and low-cost overall structure. The air guide assembly 300 rotates under the influence of airflow, thereby driving the scraper assembly 400. This rotational effect is good and eliminates the need for a motor, reducing costs. The scraper assembly 400 rotates relative to the outer periphery of the first separation cone 200 to clean debris adhering to it, preventing debris from clogging the ventilation holes and allowing for smoother airflow through the first separation cone 200.

[0095] Reference Figure 2 , Figure 10 and Figure 12 As shown, in some embodiments, the dust cup structure provided in this application further includes a mounting bracket 102, which is disposed in the dust collection chamber 101, and the first separation cone 200 is disposed on the mounting bracket 102.

[0096] In this way, the mounting bracket 102 can play a supporting role, and the first separation cone 200 is positioned and installed by the mounting bracket 102 to prevent the first separation cone 200 from shifting due to vibration or suction during use.

[0097] The first separation cone 200 can be detachably connected to the mounting bracket 102 via bolts, clips, or other structures, so that the user can disassemble the first separation cone 200 to replace or maintain the first separation cone 200, the air guide assembly 300, or the scraper assembly 400.

[0098] Reference Figure 10 and Figure 12 As shown, in some embodiments, the mounting bracket 102 divides the dust collection chamber 101 into a first separation chamber 1011 and a second separation chamber 1012 that are connected to each other. The scraping assembly 400 and part of the first separation cone 200 are disposed in the first separation chamber 1011. The air guide assembly 300 is rotatably disposed on the first separation cone 200 and located in the second separation chamber 1012. The first separation cone 200 is used to filter the airflow entering the second separation chamber 1012.

[0099] The dust cup body 100 is provided with an air inlet 103 and an air outlet 104. The air inlet 103 is connected to the first separation chamber 1011, and the air outlet 104 is connected to the second separation chamber 1012.

[0100] Among them, reference Figures 11 to 13 As shown, the arrows indicate the direction of airflow. When the suction component of the cleaning equipment is working, the airflow enters the first separation chamber 1011 through the air inlet 103, enters the second separation chamber 1012 through the first separation cone 200, and then enters the suction component through the air outlet 104.

[0101] In this way, when the airflow enters the second separation chamber 1012 from the first separation chamber 1011, the first separation chamber 1011 can collect the debris blocked by the first separation cone 200.

[0102] Furthermore, refer to Figures 11 to 13 As shown, the scraping assembly 400 is located inside the first separation chamber 1011, so that debris attached to the first separation cone 200 can fall directly into the first separation chamber 1011 after being cleaned by the scraping assembly 400. The air guide assembly 300 is located inside the second separation chamber 1012, which can prevent hair, strips and other debris from getting tangled on the air guide assembly 300 and causing the movement of the air guide assembly 300 to be obstructed.

[0103] Reference Figure 10As shown, the mounting bracket 102 can be an arc-shaped structure to guide the airflow. Thus, the airflow carrying impurities enters the first separation chamber 1011 tangentially from the inlet 103, and then undergoes circular motion under the guidance of the mounting bracket 102. Under the influence of gravity and centrifugal force, the impurities are deposited downwards to the bottom of the first separation chamber 1011, while the clean airflow enters the second separation chamber 1012 via the first separation cone 200.

[0104] Among them, reference Figure 2 , Figure 3 and Figure 10 As shown, the air guide assembly 300 is rotatably mounted on the first separation cone 200, and the scraper assembly 400 is sleeved on the outside of the first separation cone 200. The air guide assembly 300 is connected to the scraper assembly 400, thus integrating the first separation cone 200, the air guide assembly 300 and the scraper assembly 400 into one unit, making the overall structure more compact and reducing the space occupied in the dust collection chamber 101.

[0105] Reference Figure 2 , Figure 10 and Figure 11 As shown, in some embodiments, the dust cup structure provided in this application further includes a second separation cone 500, which is disposed in the second separation chamber 1012 and is used to filter the airflow entering the air outlet 104.

[0106] In this way, by setting the second separation cone 500 in the second separation chamber 1012, a two-stage separation system is formed with the first separation cone 200. The first separation cone 200 initially blocks larger debris in the first separation chamber 1011, and the second separation cone 500 further blocks smaller debris in the second separation chamber 1012, thereby effectively improving the filtration effect on the airflow.

[0107] Reference Figure 10 , Figure 11 and Figure 14 As shown, the second separation cone 500 includes a housing portion 510 and an air outlet duct portion 520. The housing portion 510 has an inner cavity and gradually tapers from a first end to a second end to form a cone shape. The second end of the housing portion 510 is open and communicates with the second separation cavity 1012. The air outlet duct portion 520 is inserted into the first end of the housing portion 510 and connects the air outlet 104 with the inner cavity of the housing portion 510. An air inlet channel 530 is also provided on one side of the housing portion 510, and the air inlet channel 530 is correspondingly arranged with the air outlet duct portion 520.

[0108] In this way, the airflow carrying small impurities enters the inner cavity of the housing 510 tangentially through the air inlet channel 530, and undergoes circular motion under the guidance of the conical structure of the housing 510. Under the influence of gravity and centrifugal force, the impurities are deposited downwards along the housing 510 to the bottom of the second separation chamber 1012, while the clean airflow enters the air outlet 104 through the air outlet duct 520.

[0109] Among them, reference Figure 10 and Figure 11 As shown, the air inlet channel 530 and the side wall of the air outlet duct 520 are respectively arranged. When the airflow with small impurities enters the inner cavity of the housing 510 through the air inlet channel 530, it can be blocked by the side wall of the air outlet duct 520 to prevent impurities from directly entering the air outlet 104 through the air outlet duct 520.

[0110] Reference Figure 1 , Figure 2 and Figure 10 As shown, in some embodiments, the dust cup structure provided in this application further includes a filter element 600, which is disposed at the air outlet 104.

[0111] In this way, the filter element 600 intercepts the dust entering the air outlet 104, preventing the dust from entering the suction component of the cleaning equipment through the air outlet 104 and causing damage to the suction component.

[0112] For example, filter element 600 can be HEPA filter, screen filter, etc.

[0113] Reference Figure 2 As shown, in some embodiments, a seal 700 is provided between the first separating cone 200 and the mounting bracket 102.

[0114] In this way, the gap between the first separation cone 200 and the mounting bracket 102 is filled by the seal 700 to prevent debris from entering the second separation chamber 1012 through the gap between the two from passing through the first separation chamber 1011.

[0115] For example, the seal 700 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.

[0116] Reference Figure 3 , Figure 10 and Figure 12 As shown, in some embodiments, the scraping assembly 400 includes a support frame 410 and at least one scraping strip 420.

[0117] The support frame 410 is sleeved on the outside of the first separation cone 200 and is connected to the air guide assembly 300. The scraper 420 is disposed on the support frame 410 and abuts against the outer periphery of the first separation cone 200. The scraper 420 is used to clean debris on the first separation cone 200.

[0118] Thus, the support frame 410 is fitted onto the outside of the first separation cone 200 to support the scraper strip 420. Under the action of the air guide assembly 300, the support frame 410 can rotate relative to the first separation cone 200, thereby allowing the scraper strip 420 to clean debris from the first separation cone 200.

[0119] The scraper strip 420 covers a partial area of ​​the outer side of the first separation cone 200 to ensure that the first separation cone 200 has sufficient air intake area. It is understood that there is at least one scraper strip 420, and the number of scraper strips 420 can be one. The number of scraper strips 420 can also be multiple, with multiple scraper strips 420 spaced apart on the support frame 410. This embodiment does not impose further limitations in this regard.

[0120] For example, the shape of the support frame 410 can match the shape of the first separating cone 200, and there are no specific restrictions on this.

[0121] Reference Figure 3 , Figure 4 and Figure 10 As shown, in some embodiments, the support frame 410 includes a support ring portion 411 and a first connecting portion 412. The support ring portion 411 is sleeved on the outside of the first separating cone 200, and the first connecting portion 412 passes through the first separating cone 200 and is connected to the air guide assembly 300. A scraper strip 420 is disposed between the support ring portion 411 and the first connecting portion 412.

[0122] In this way, by placing the scraper 420 between the support ring 411 and the first connecting part 412, it is ensured that the scraper 420 always abuts against the outside of the first separating cone 200 during rotation, thereby improving cleaning efficiency and preventing the scraper 420 from disengaging from the outside of the first separating cone 200 due to centrifugal force.

[0123] Reference Figure 3 , Figure 4 and Figure 10 As shown, the first connecting part 412 passes through the first separating cone 200, so as to be detachably connected to the air guide assembly 300 located in the second separating chamber 1012. The first connecting part 412 and the air guide assembly 300 can be detachably connected by bolts, clips or other structures, so as to facilitate replacement and maintenance.

[0124] Reference Figure 5As shown, in some embodiments, a scraping film 421 is provided on the side of the scraping strip 420 facing the first separation cone 200.

[0125] In this way, the scraping sheet 421 elastically abuts against the outer side of the first separating cone 200, and its flexibility allows it to closely adhere to the outer surface of the first separating cone 200, thereby improving cleaning efficiency.

[0126] For example, the scraping film 421 can be made of elastic materials such as silicone film or rubber film, and this application embodiment does not impose too many restrictions on it.

[0127] Reference Figure 3 , Figure 10 and Figure 12 As shown, in some embodiments, the air guide assembly 300 is disposed inside the first separation cone 200.

[0128] In this way, the scraper assembly 400 and the air guide assembly 300 are respectively disposed on the inner and outer sides of the first separation cone 200. The air guide assembly 300, the scraper assembly 400 and the first separation cone 200 are integrated together, making the overall structure more compact and reducing the space occupied in the dust collection chamber 101.

[0129] Specifically, the first connecting part 412 of the scraping assembly 400 passes through the first separating cone 200 and extends to the inner side of the first separating cone 200 to connect with the air guide assembly 300.

[0130] Reference Figure 6 , Figure 7 and Figure 10 As shown, in some embodiments, the air guide assembly 300 includes a connector 310 and an impeller 330. The connector 310 is rotatably disposed within the first separation cone 200 and is connected to the scraper assembly 400. The impeller 330 is connected to the connector 310, and one end of the impeller 330 away from the connector 310 is rotatably connected to the dust cup body 100; the impeller 330 is configured to rotate under the influence of the airflow within the dust collection chamber 101 and, through the connector 310, drive the scraper assembly 400 to rotate.

[0131] In this way, the impeller 330 rotates relative to the first separation cone 200 under the drive of the airflow, and drives the scraper assembly 400 to rotate through the connector 310, thereby cleaning the debris on the outside of the first separation cone 200.

[0132] Reference Figure 2 , Figure 3 and Figure 12 As shown, in some embodiments, the air guide assembly 300 further includes a flow guide 320 that connects the impeller assembly 330 and the connector 310. The flow guide 320 is configured to guide airflow onto the impeller assembly 330.

[0133] In this way, the airflow is concentrated by the guide member 320 and guided to flow toward the impeller member 330, so as to increase the force of the airflow on the impeller member 330, thereby increasing the speed and output power of the impeller member 330.

[0134] Among them, reference Figure 2 , Figure 3 and Figure 7 As shown, the flow guide 320 includes a body portion 321 with openings at both ends, and the impeller 330 has multiple blades. The blades are arranged corresponding to one of the openings of the body portion 321, so that the airflow is guided to the blades of the impeller 330 through the body portion 321 to increase the force of the airflow on the impeller 330.

[0135] Furthermore, the flow guide 320 also includes a plurality of flow guide fin portions 322, which are disposed within the body portion 321 and spaced circumferentially around the main axis of the body portion 321. The blades of the impeller 330 are correspondingly disposed with respect to the flow guide fin portions 322 of the flow guide 320. (Refer to...) Figure 3 As shown, the rotational tilt direction of the guide fin portion 322 is opposite to the rotational tilt direction of the blade, so as to ensure that the airflow between the guide fin portions 322 can blow directly onto the concave surface of the blade, thereby increasing the force of the airflow on the impeller component 330.

[0136] For example, in some embodiments, the guide fin portion 322 is right-handed tilted, and the blades are left-handed tilted. In other embodiments, the guide fin portion 322 is left-handed tilted, and the blades are right-handed tilted.

[0137] Specifically, refer to Figure 5 , Figure 6 , Figure 7 and Figure 10 As shown, the first connecting portion 412 of the scraping assembly 400 has openings at both ends, and a first connecting platform 4121 is provided on the inner side of the first connecting portion 412, with a through hole on the first connecting platform 4121. The connecting member 310 of the air guide assembly 300 has a connecting hole 311 at the end away from the air guide member 320, so that the fastener can pass through the through hole and connect to the connecting hole 311, thereby realizing a detachable connection between the first connecting portion 412 and the connecting member 310.

[0138] For example, the fastener can be a bolt, and the connecting hole 311 can be a threaded hole. The fastener can also be a snap-fit, and the connecting hole 311 can also be a slot.

[0139] Furthermore, refer to Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, at least one first limiting part 4122 is provided on the inner side of the first connecting part 412, and at least one second limiting part 312 is provided on the connector 310. The first limiting part 4122 and the second limiting part 312 are inserted into each other to play a role in positioning and preventing rotation.

[0140] For example, refer to Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the first limiting part 4122 can be a plug-in block, and the second limiting part 312 can be a matching plug-in slot. Of course, in another embodiment, the first limiting part 4122 can also be a plug-in slot, and the second limiting part 312 can also be a matching plug-in block.

[0141] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the main body 321 of the flow guide 320 is provided with a mounting groove 3211 for corresponding insertion of the impeller 330.

[0142] Reference Figure 10 and Figure 12 As shown, in some embodiments, a first bearing member 210 is provided on the first separation cone 200, and a connecting member 310 is connected to the inner ring of the first bearing member 210.

[0143] In this way, by setting the first bearing component 210, the rotational resistance of the connecting component 310 is reduced.

[0144] Reference Figure 10 and Figure 12 As shown, in some embodiments, a second bearing component 105 is provided on the dust cup body 100, and the impeller component 330 is connected to the inner ring of the second bearing component 105.

[0145] In this way, by setting the second bearing component 105, the rotational resistance of the impeller component 330 is reduced.

[0146] Among them, reference Figure 6 , Figure 7 and Figure 10 As shown, the connector 310 is provided with a positioning protrusion 313, which connects to the inner ring of the first bearing component 210. During assembly, the connector 310 is inserted into the inner ring of the first bearing component 210 until the positioning protrusion 313 abuts against the inner ring of the first bearing component 210. This allows the connector 310 to be installed in the appropriate position, ensuring that the first connecting part 412 of the scraper assembly 400 and the impeller component 330 are connected in place.

[0147] Reference Figure 8 , Figure 9 and Figure 12As shown, in some embodiments, the first separating cone 200 is provided with a mounting part 220, and the mounting part 220 is provided with a mounting through hole 221, through which the scraping assembly 400 and the air guiding assembly 300 are connected.

[0148] In this way, the scraper assembly 400 and the air guide assembly 300 can be connected through the mounting through hole 221 to make the overall structure more compact.

[0149] Specifically, refer to Figure 8 , Figure 9 and Figure 12 As shown, a second connecting platform 222 is provided in the mounting through hole 221. The second connecting platform 222 is provided with a through hole. The first bearing component 210 is provided on the second connecting platform 222. The connector 310 passes through the through hole and is connected to the first connecting part 412.

[0150] Reference Figure 2 , Figure 3 and Figure 8 As shown, in some embodiments, the first separating cone 200 includes a main body 201 and a second connecting part 202. An air guide assembly 300 is rotatably disposed inside the main body 201, a scraper assembly 400 is sleeved on the outside of the main body 201, and a mounting part 220 is disposed on the main body 201. The second connecting part 202 is disposed on the main body 201 and is detachably connected to the mounting bracket 102.

[0151] In this way, the airflow entering the second separation chamber 1012 can be filtered by the main body 201, and impurities can be blocked in the first separation chamber 1011. The second connecting part 202 is used to fix the main body 201 to the mounting bracket 102.

[0152] Among them, reference Figure 2 , Figure 8 and Figure 12 As shown, at least one first positioning part 203 is provided on the second connecting part 202, and at least one second positioning part 1021 is provided on the mounting bracket 102. The first positioning part 203 is connected to the second positioning part 1021 so as to realize the detachable connection between the second connecting part 202 and the mounting bracket 102.

[0153] For example, refer to Figure 2 , Figure 8 and Figure 12As shown, the first positioning part 203 may be provided with a through hole, and the second positioning part 1021 may be provided with a threaded hole. The second positioning part 1021 is inserted into the through hole of the first positioning part 203, so that the first positioning part 203 and the second positioning part 1021 can be connected by bolts. In some other embodiments, either the first positioning part 203 or the second positioning part 1021 can be a snap-fit, and the other can be a matching slot, connected by a snap-fit ​​method. The embodiments of this application do not impose too many limitations on this.

[0154] Reference Figure 1 , Figure 2 , Figure 10 and Figure 12 As shown, the dust cup body 100 includes a cup body portion 110 and a cover portion 120, with the cover portion 120 covering the cup body portion 110 to form a dust collection chamber 101. An air outlet 104 and a mounting bracket 102 are disposed on the cup body portion 110, and an air inlet 103 and a second separation cone 500 are disposed on the cover portion 120.
