Description

Technical Field

[0001] This application relates to the field of environmental cleaning electrical appliances, and in particular to a dust cup structure and cleaning device. Background Technology

[0002] In related technologies, household cleaning equipment such as vacuum cleaners may include a main unit and a dust collection assembly. The main unit has a suction component, which generates negative pressure to collect dust and other impurities from the floor into the dust collection assembly. The dust collection assembly includes a dust cup, a cyclone separator, and filter cotton. The cyclone separator is located inside the dust cup, forming a separation chamber between the dust cup and the cyclone separator. The dust cup has an air inlet and an air outlet, allowing airflow to enter from the air inlet and rotate in the separation chamber for initial centrifugal separation. The filter cotton is located between the outlet and the air outlet of the cyclone separator, allowing the initially separated airflow to pass through the cyclone separator and undergo secondary filtration by the filter cotton before being discharged from the air outlet. The centrifugally separated dust and other particles are deposited at the bottom of the dust cup.

[0003] However, the filtration effect of the filter cotton in the relevant technology is poor. Utility Model Content

[0004] Based on this, this application provides a dust cup structure and a cleaning device to address the shortcomings of related technologies.

[0005] In a first aspect, this application provides a dust cup structure, including a first cup body, a cyclone tube, an air guide assembly, and a first filter assembly. The cyclone tube is connected to the first cup body and is located inside the first cup body. A separation chamber is defined between the first cup body and the cyclone tube. The cyclone tube has an air outlet chamber and a first air outlet. The first air outlet is located at one end of the cyclone tube. The separation chamber, the air outlet chamber, and the first air outlet are connected in sequence.

[0006] An air guide assembly is disposed at the first air outlet. The air guide assembly includes a guide member, which includes a first guide section and a second guide section. The first guide section is conical, and the end of the first guide section near the air outlet cavity is smaller than the end of the first guide section away from the air outlet cavity. The second guide section is connected to the end of the first guide section away from the air outlet cavity, and the second guide section is folded outward toward the outside of the first guide section. A first filter assembly is disposed at the end of the guide member away from the air outlet cavity.

[0007] The dust cup structure provided in this application forms a separation chamber by setting a first cup body and a cyclone to perform initial centrifugal separation of the fluid. An air outlet and a first air outlet allow the fluid separated by the initial centrifugal separation to flow out. A conical first guide section and an outwardly folded second guide section form a guide surface on the side of the guide section facing the air outlet, guiding the fluid to flow in various radial directions along the cyclone. This results in a lower flow velocity and more dispersed flow direction of the fluid flowing to the first filter assembly. The first filter assembly performs secondary filtration and separation of the fluid. After being guided by the guide section, the fluid velocity decreases, thereby reducing the working pressure of the first filter assembly. The dispersed flow of the fluid in various directions allows the fluid to pass through various areas of the first filter assembly, thus improving the filtration efficiency of the first filter assembly. This improves the filtration effect of the first filter assembly.

[0008] In one possible implementation, there is a gap t between the end of the second guide portion away from the air outlet cavity and the side of the first filter assembly facing the guide portion;

[0009] The spacing t satisfies: t≥5mm.

[0010] This allows the fluid to be evenly distributed on the first filter element and increases the contact time between the fluid and the first filter element, thereby improving the filtration and separation effect of the first filter element.

[0011] In one possible implementation, the projection of the air guide on the reference plane covers the projection of the first air outlet on the reference plane;

[0012] The reference plane is parallel to the radial direction of the cyclone.

[0013] Thus, the fluid discharged from the first air outlet can flow radially along the cyclone after being guided by the guide component, and then enter the space between the first filter component and the guide component. The guide component has a good deflection effect, which can effectively disperse the flow direction of the fluid and uniformly distribute the flow speed of the fluid.

[0014] In one possible implementation, the air guide assembly further includes several support ribs, which are spaced apart circumferentially along the air guide. The support ribs are connected between the outer peripheral wall of the air guide and the inner peripheral wall of the first air outlet, and an air guide channel is defined between the air guide and the support ribs.

[0015] In this way, the support ribs can connect the flow guide to the cyclone, and after several support ribs are set at intervals along the circumference of the flow guide, they can work together with the flow guide to divide the first air outlet into multiple air guide channels, thereby allowing the fluid to flow out after being dispersed through the air guide channels, thus effectively reducing the flow velocity of the fluid and dispersing the flow direction of the fluid.

[0016] In one possible implementation, the dust cup structure further includes a second cup body, with the first cup body connected to the second cup body. A dust storage chamber is defined between the second cup body and the first cup body. The second cup body has an air inlet, an installation chamber, and a second air outlet. The air inlet is connected to the separation chamber. The first cup body has a dust ejection port, which is connected to the separation chamber and the dust storage chamber.

[0017] There is a partition between the mounting cavity and the dust storage cavity. The dust storage cavity and the mounting cavity are located at both ends of the second cup body. The second air outlet is located at the end of the mounting cavity away from the dust storage cavity. The end of the mounting cavity away from the dust storage cavity is connected to the first air outlet. The first filter assembly is disposed in the mounting cavity.

[0018] Thus, the fluid enters the separation chamber through the air inlet and rotates around the cyclone under the action of suction, thereby performing the initial centrifugal separation of large solid particles in the fluid. The separated large solid particles enter the dust storage chamber through the ash throwing port and are then deposited in the dust storage chamber. After that, the fluid that has been initially centrifugally separated can enter the air outlet chamber and, after being decelerated and dispersed by the flow guiding component, enter the installation chamber from the first air outlet. After being filtered and separated by the first filter component, it is discharged from the dust cup structure from the second air outlet.

[0019] In one possible implementation, the dust cup structure further includes a second filter assembly disposed on the side of the first filter assembly away from the cyclone.

[0020] In this way, the cyclone can perform initial centrifugal separation of the fluid, the first filter component can perform a second separation and filtration of the fluid, and the second filter component can perform a third separation and filtration of the fluid. After that, the fluid is discharged from the second air outlet and enters the main unit. In this way, multiple filtration and separation can improve the dust and gas separation effect of the dust cup structure, thereby preventing dust from entering the main unit or preventing dust from flowing back into the environment.

[0021] In one possible implementation, the cyclone includes a filter screen, which is at least disposed on the peripheral wall of the cyclone to connect the separation chamber and the air outlet chamber.

[0022] Thus, after the fluid undergoes initial centrifugal separation in the separation chamber, the fluid that has undergone initial centrifugal separation can pass through the filter screen to enter the air outlet chamber, and then enter the installation chamber from the first air outlet for secondary filtration and separation. Meanwhile, the large solid particles that are separated are intercepted by the filter screen in the separation chamber.

[0023] In one possible implementation, the filter screen includes a first filter screen and a second filter screen, the first filter screen being disposed on the peripheral wall of the cyclone, and the second filter screen being disposed on the bottom wall of the cyclone away from the first air outlet.

[0024] Thus, when the cyclone separator is equipped with a first filter screen on its circumferential wall, the fluid rotates around the cyclone separator, and large solid particles are separated from the fluid by the combined action of centrifugal force and gravity. The first filter screen can intercept large solid particles in the separation chamber and allow the gas in the separation chamber to enter the outlet chamber. When the bottom wall of the cyclone separator is equipped with a second filter screen, the separated large solid particles enter the dust storage chamber from the ash throwing port under the action of centrifugal force. Then, the large solid particles can move towards the bottom of the dust storage chamber under the action of the gas, thereby causing the large solid particles to be deposited at the bottom of the dust storage chamber, thus improving the dust collection effect of the dust storage chamber.

[0025] In one possible implementation, the dust cup structure also includes a baffle, the bottom wall of the cyclone is connected to the bottom wall of the first cup body, and the baffle is connected to the end of the first cup body away from the first air outlet.

[0026] The dust storage chamber includes a first dust storage chamber and a second dust storage chamber that are interconnected. The first dust storage chamber is located to the side of the separation chamber, and the second dust storage chamber is located at the bottom of the separation chamber away from the first air outlet. A baffle is installed between the first dust storage chamber and the second dust storage chamber.

[0027] Thus, when large solid particles are deposited at the bottom of the second dust storage chamber, the baffle installed between the first and second dust storage chambers can prevent the large solid particles deposited in the second dust storage chamber from moving to the first dust storage chamber, thereby preventing the large solid particles from flowing back to the separation chamber through the ash throwing port, thereby improving the dust collection effect of the dust storage chamber.

[0028] In one possible implementation, the distance between the end of the baffle away from the first cup body and the wall of the second dust storage chamber away from the first air outlet is less than or equal to 25 mm.

[0029] In this way, the baffle can effectively prevent large solid particles that have already been deposited in the second dust storage chamber from moving to the first dust storage chamber, thereby improving the dust collection effect of the second dust storage chamber.

[0030] In one possible implementation, the diameter d of the cyclone tube and the diameter D of the first cup body satisfy: d / D≤1 / 2; and / or, the distance between the inner peripheral wall of the first cup body and the outer peripheral wall of the cyclone tube is greater than or equal to 20 mm.

[0031] This increases the radial distance between the cyclone separator and the first cup, allowing the fluid to rotate and separate away from the cyclone separator due to inertia after entering the separation chamber. This prevents solids in the fluid from clogging the filter screen and also increases the rotation radius of the fluid, thereby increasing the centrifugal force and improving the centrifugal separation effect of the separation chamber.

[0032] Secondly, this application provides a cleaning device, including a main unit and the dust cup structure provided in the first aspect, wherein the dust cup structure is connected to the main unit.

Detailed Implementation

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] In related technologies, household cleaning equipment such as vacuum cleaners may include a main unit and a dust collection assembly. The main unit has a suction component, which generates negative pressure to collect dust and other impurities from the floor into the dust collection assembly. The dust collection assembly includes a dust cup, a cyclone separator, and filter cotton. The cyclone separator is located inside the dust cup, forming a separation chamber between the dust cup and the cyclone separator. The dust cup has an air inlet and an air outlet, allowing airflow to enter from the air inlet and rotate in the separation chamber for initial centrifugal separation. The filter cotton is located between the outlet and the air outlet of the cyclone separator, allowing the initially separated airflow to pass through the cyclone separator and undergo secondary filtration by the filter cotton before being discharged from the air outlet. The centrifugally separated dust and other particles are deposited at the bottom of the dust cup.

[0051] However, the filtration effect of the filter cotton in the related technology is poor. This is because the airflow direction discharged from the cyclone separator is along the axial direction of the cyclone separator, and the airflow velocity is relatively fast, which causes the airflow to directly impact the filter cotton, thereby reducing the filtration effect of the filter cotton. In addition, the airflow direction discharged from the cyclone separator is along the axial direction of the cyclone separator, which causes the airflow to concentrate in the area corresponding to the filter cotton and the cyclone separator, while less airflow passes through other areas of the filter cotton, thus reducing the filtration efficiency of the filter cotton.

[0052] In view of this, the present application provides a dust cup structure, which provides a flow guide at the first air outlet of the cyclone to guide the fluid to flow radially along the cyclone, thereby reducing the flow rate of the fluid when passing through the first filter assembly and making the fluid pass through each area of ​​the first filter assembly evenly, thereby improving the filtration effect of the first filter assembly.

[0053] 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.

[0054] Reference Figure 1As shown in the illustration, this application provides a cleaning device, which includes a main unit and a dust cup structure connected to the main unit. The main unit provides suction power to the cleaning device, thereby removing dust and other particulate matter from the surface to be cleaned, while the dust cup structure separates and collects dust.

[0055] The cleaning equipment can be household cleaning equipment such as vacuum cleaners and floor scrubbers, but this application does not limit it to this embodiment.

[0056] Reference Figures 1 to 6 As shown, based on the above embodiments, this application embodiment also provides a dust cup structure, which includes a first cup body 100, a cyclone 200, an air guide assembly 400, and a first filter assembly 500. The cyclone 200 is connected to the first cup body 100 and is located inside the first cup body 100. A separation chamber 300 is defined between the first cup body 100 and the cyclone 200. The cyclone 200 has an air outlet chamber 210 and a first air outlet 220. The first air outlet 220 is located at one end of the cyclone 200. The separation chamber 300, the air outlet chamber 210, and the first air outlet 220 are connected in sequence.

[0057] An air guide assembly 400 is disposed at the first air outlet 220. The air guide assembly 400 includes a guide member 410, which includes a first guide portion 411 and a second guide portion 412. The first guide portion 411 is conical, and the end of the first guide portion 411 near the air outlet cavity 210 is smaller than the end of the first guide portion 411 away from the air outlet cavity 210. The second guide portion 412 is connected to the end of the first guide portion 411 away from the air outlet cavity 210, and the second guide portion 412 is folded outward toward the first guide portion 411. A first filter assembly 500 is disposed at the end of the guide member 410 away from the air outlet cavity 210.

[0058] In this embodiment, the first cup body 100 and the cyclone 200 work together to perform initial centrifugal separation of the fluid, while the first filter assembly 500 performs secondary filtration and separation of the fluid. This synergistic effect improves the dust-gas separation efficiency of the dust cup structure. The air guide assembly 400 reduces the fluid velocity and disperses the fluid flow direction, thereby improving the filtration efficiency of the first filter assembly 500.

[0059] A separation chamber 300 is formed between the inner wall of the first cup body 100 and the outer wall of the cyclone 200, so that the mixed fluid entering the dust cup structure undergoes initial centrifugal separation in the separation chamber 300, thereby separating large solid particles from the mixed fluid. The inner wall of the cyclone 200 forms an air outlet chamber 210, and one end of the cyclone 200 is open to form a first air outlet 220. In this way, the gas undergoing initial centrifugal separation in the separation chamber 300 can enter the air outlet chamber 210 and flow out from the first air outlet 220.

[0060] It should be understood that during the flow of fluid from the air outlet 210 to the first air outlet 220, its flow direction is mainly along the axial direction of the cyclone 200. Since the first air outlet 220 is provided with a guide 410, which includes a conical first guide portion 411 and an outwardly folded second guide portion 412, the guide 410 can form a guide surface 413 on the side facing the air outlet 210. The guide surface 413 can guide the flow direction of the fluid from the axial direction of the cyclone 200 to the radial directions of the cyclone 200. During this process, the guide surface 413 can disperse a large airflow into multiple small airflows before they flow out, thereby reducing the fluid velocity and the working pressure of the first filter assembly 500, thus improving the filtration and separation effect of the first filter assembly 500.

[0061] At the same time, the flow direction of the fluid changes from the axial direction of the cyclone 200 to the radial direction of the cyclone 200, and is dispersed into multiple small airflows before flowing out. This allows the fluid to be evenly distributed in various areas of the side of the first filter assembly 500 when it flows to the side of the first filter assembly 500 facing the guide member 410, rather than being concentrated in the area directly opposite the first filter assembly 500 and the first air outlet 220. This allows the fluid to pass through various areas of the first filter assembly 500, thereby improving the filtration and separation efficiency of the first filter assembly 500.

[0062] The dust cup structure provided in this embodiment includes a first cup body 100, a cyclone 200, a separation chamber 300, an air guide assembly 400, and a first filter assembly 500. The cyclone 200 includes an air outlet chamber 210 and a first air outlet 220. The air guide assembly 400 includes a guide member 410, which includes a first guide portion 411 and a second guide portion 412. The first cup body 100 and the cyclone 200 are used to jointly form the separation chamber 300, which is used for initial centrifugal separation of the fluid. The air outlet chamber 210 and the first air outlet 220 are used to allow the initially centrifuged fluid to flow out. The conical first guide portion 411 and the outwardly folded second guide portion 412 form a guide surface 413 on the side of the guide member 410 facing the air outlet chamber 210, so that the guide surface 413 guides the fluid along the radial directions of the cyclone 200. The fluid flows in a dispersed manner, resulting in a lower flow velocity and more dispersed flow direction for the fluid flowing to the first filter assembly 500. By using the first filter assembly 500 for secondary filtration and separation, and with the fluid velocity reduced after being guided by the guide member 410, the operating pressure of the first filter assembly 500 is reduced. The dispersed flow of the fluid in various directions allows it to pass through all areas of the first filter assembly 500, thereby improving its filtration and separation efficiency. This enhances the filtration and separation effect of the first filter assembly 500.

[0063] Reference Figure 2 As shown, in one possible implementation, the end of the second guide section 412 facing away from the air outlet cavity 210 has a distance t between it and the side of the first filter assembly 500 facing the guide member 410. The distance t satisfies: t ≥ 5 mm.

[0064] It should be understood that if the guide element 410 is too close to the first filter element 500, the fluid may concentrate in certain areas of the first filter element 500, resulting in an uneven filtration effect. An appropriate spacing t can help the fluid to be evenly distributed on the first filter element 500. Moreover, an appropriate spacing t can ensure that the fluid has sufficient contact time when passing through the first filter element 500, thereby improving the filtration efficiency of the first filter element 500.

[0065] Therefore, with the above-mentioned configuration, the spacing t can be greater than or equal to 5 mm, thereby making the fluid evenly distributed on the first filter component 500 and increasing the contact time between the fluid and the first filter component 500, thereby improving the filtration and separation effect of the first filter component 500.

[0066] In some embodiments, the projection of the guide member 410 onto the reference plane overlaps the projection of the first air outlet 220 onto the reference plane. The reference plane is parallel to the radial direction of the cyclone 200.

[0067] In this way, the fluid discharged from the first air outlet 220 can flow radially along the cyclone 200 after being guided by the guide member 410, and then enter the space between the first filter assembly 500 and the guide member 410. The guide member 410 has a good deflection effect, which can effectively disperse the flow direction of the fluid and uniformly distribute the flow speed of the fluid.

[0068] Reference Figures 4 to 6 As shown, in one possible implementation, the air guide assembly 400 further includes a plurality of support ribs 420, which are spaced apart along the circumference of the air guide 410. The support ribs 420 are connected between the outer peripheral wall of the air guide 410 and the inner peripheral wall of the first air outlet 220, and an air guide channel 430 is defined between the air guide 410 and the support ribs 420.

[0069] With this configuration, the support ribs 420 can connect the guide 410 to the cyclone 200. After several support ribs 420 are spaced apart along the circumference of the guide 410, they can work together with the guide 410 to divide the first air outlet 220 into multiple air guide channels 430, thereby dispersing the fluid through the air guide channels 430 and flowing out, thus effectively reducing the fluid velocity and dispersing the flow direction of the fluid.

[0070] Reference Figures 1 to 3 , Figures 5 to 8 As shown, in one possible implementation, the dust cup structure further includes a second cup body 600, with the first cup body 100 connected within the second cup body 600. A dust storage chamber 700 is defined between the second cup body 600 and the first cup body 100. The second cup body 600 has an air inlet 610, an installation cavity 620, and a second air outlet 630. The air inlet 610 communicates with the separation chamber 300. The first cup body 100 has a dust ejection port 110, which communicates with the separation chamber 300 and the dust storage chamber 700.

[0071] A partition 640 is provided between the mounting cavity 620 and the dust storage cavity 700. The dust storage cavity 700 and the mounting cavity 620 are located at both ends of the second cup body 600. The second air outlet 630 is located at the end of the mounting cavity 620 away from the dust storage cavity 700. The end of the mounting cavity 620 away from the dust storage cavity 700 is connected to the first air outlet 220. The first filter assembly 500 is disposed in the mounting cavity 620.

[0072] It is understandable that the second cup 600 and the first cup 100 can be nested inside each other, and the second cup 600 can be coaxially arranged with the first cup 100, thereby forming a dust storage chamber 700 between the second cup 600 and the first cup 100. The dust storage chamber 700 can be an annular cavity, surrounding the outer periphery of the separation chamber 300. Alternatively, the first cup 100 can be disposed inside the second cup 600, and the first cup 100 and part of the second cup 600 can also be arranged side by side, with the first cup 100 and the second cup 600 sharing part of the cup wall, thereby making the dust storage chamber 700 and the separation chamber 300 arranged side by side along the radial direction of the cyclone 200.

[0073] For example Figure 2 and Figure 7 The dust cup structure shown has a shared sidewall between the first cup body 100 and the second cup body 600. The cyclone 200 and the first cup body 100 are nested together. The shared bottom wall between the cyclone 200 and the first cup body 100 is also present. A dust storage chamber 700 is formed between the inner wall of the second cup body 600 and the outer wall of the first cup body 100. The dust storage chamber 700 can be used to store separated solid particles such as dust. A separation chamber 300 is formed between the outer wall of the cyclone 200 and the inner wall of the first cup body 100, so that the mixed fluid can enter the separation chamber 300. Centrifugal separation is performed. The separation chamber 300 and part of the dust storage chamber 700 are arranged side by side in the radial direction of the cyclone 200. The inner wall of the cyclone 200 forms an air outlet 210. One end of the cyclone 200 is open to form a first air outlet 220 to connect the air outlet 210 and the mounting chamber 620. The common side wall of the first cup body 100 and the second cup body 600 has an air inlet 610 to connect the separation chamber 300 and the main unit. The side wall of the first cup body 100 has a dust throwing port 110 to connect the separation chamber 300 and the dust storage chamber 700.

[0074] In this way, the fluid enters the separation chamber 300 through the air inlet 610 and rotates around the cyclone 200 under the action of suction, thereby performing the initial centrifugal separation of large solid particles in the fluid. The separated large solid particles enter the dust storage chamber 700 through the dust discharge port 110 and are deposited in the dust storage chamber 700. After that, the fluid that has been initially centrifuged can enter the air outlet chamber 210 and, after being decelerated and dispersed by the flow guiding component, enter the installation chamber 620 from the first air outlet 220. After being filtered and separated by the first filter component 500, it is discharged from the dust cup structure from the second air outlet 630.

[0075] Reference Figure 1 , Figure 2 and Figure 7 As shown, in one possible implementation, the dust cup structure further includes a second filter assembly 800, which is disposed on the side of the first filter assembly 500 away from the cyclone 200.

[0076] In this way, the cyclone 200 can perform initial centrifugal separation of the fluid, the first filter component 500 can perform secondary separation and filtration of the fluid, and the second filter component 800 can perform tertiary separation and filtration of the fluid. After that, the fluid is discharged from the second air outlet 630 and enters the main unit. In this way, multiple filtration and separation can improve the dust and gas separation effect of the dust cup structure, thereby preventing dust from entering the main unit or preventing dust from flowing back into the environment.

[0077] The second filter component 800 can also be installed in the mounting cavity 620.

[0078] Reference Figure 2 As shown, in some embodiments, the cyclone 200 includes a filter 230, which is at least disposed on the peripheral wall of the cyclone 200 to connect the separation chamber 300 and the air outlet chamber 210.

[0079] With this configuration, after the fluid undergoes initial centrifugal separation in the separation chamber 300, the fluid after initial centrifugal separation can pass through the filter screen 230 to enter the air outlet chamber 210, and then enter the installation chamber 620 from the first air outlet 220 for secondary filtration and separation. Meanwhile, the large solid particles separated out are intercepted by the filter screen 230 in the separation chamber 300.

[0080] Reference Figure 7 As shown, in one possible implementation, the filter 230 includes a first filter 231 and a second filter 232. The first filter 231 is disposed on the peripheral wall of the cyclone 200, and the second filter 232 is disposed on the bottom wall of the cyclone 200 opposite to the first air outlet 220.

[0081] Thus, when the cyclone 200 is equipped with a first filter screen 231 on its peripheral wall, the fluid rotates around the cyclone 200 in a circumferential direction. Large solid particles are then separated from the fluid by the combined action of centrifugal force and gravity. The first filter screen 231 can intercept large solid particles in the separation chamber 300 and allow the gas in the separation chamber 300 to enter the outlet chamber 210. When the bottom wall of the cyclone 200 is equipped with a second filter screen 232, the separated large solid particles enter the dust storage chamber 700 from the ash throwing port 110 under the action of centrifugal force. Afterward, the large solid particles can move towards the bottom of the dust storage chamber 700 under the action of the gas, thereby causing the large solid particles to be deposited at the bottom of the dust storage chamber 700, thus improving the dust collection effect of the dust storage chamber 700.

[0082] Reference Figure 2 As shown, in one possible implementation, the dust cup structure further includes a baffle 900. The bottom wall of the cyclone 200 is connected to the bottom wall of the first cup body 100, and the baffle 900 is connected to the end of the first cup body 100 away from the first air outlet 220. The dust storage chamber 700 includes a first dust storage chamber 710 and a second dust storage chamber 720 that are interconnected. The first dust storage chamber 710 is located to the side of the separation chamber 300, and the second dust storage chamber 720 is located at the bottom of the separation chamber 300 away from the first air outlet 220. The baffle 900 is disposed between the first dust storage chamber 710 and the second dust storage chamber 720.

[0083] In this way, when large solid particles are deposited at the bottom of the second dust storage chamber 720, the baffle 900 installed between the first dust storage chamber 710 and the second dust storage chamber 720 can prevent the large solid particles deposited in the second dust storage chamber 720 from moving to the first dust storage chamber 710, thereby preventing the large solid particles from flowing back to the separation chamber 300 through the ash discharge port 110, thus improving the dust collection effect of the dust storage chamber 700.

[0084] It is understandable that when the distance between the end of the baffle 900 away from the first cup body 100 and the bottom wall of the second cup body 600 away from the first air outlet 220 is large, the baffle 900 is effective in blocking large solid particles. Therefore, in one possible implementation, the distance between the end of the baffle 900 away from the first cup body 100 and the cavity wall of the second dust storage chamber 720 away from the first air outlet 220 is less than or equal to 25 mm.

[0085] This configuration allows the baffle 900 to effectively prevent large solid particles that have already been deposited in the second dust storage chamber 720 from moving to the first dust storage chamber 710, thereby improving the dust collection efficiency of the second dust storage chamber 720.

[0086] Reference Figure 8As shown, in some embodiments, the diameter d of the cyclone 200 and the diameter D of the first cup 100 satisfy: d / D≤1 / 2; and / or, the distance between the inner peripheral wall of the first cup 100 and the outer peripheral wall of the cyclone 200 is greater than or equal to 20 mm.

[0087] In other words, it can be that the diameter d of the cyclone 200 and the diameter D of the first cup 100 satisfy d / D≤1 / 2; it can also be that the distance between the inner peripheral wall of the first cup 100 and the outer peripheral wall of the cyclone 200 is greater than or equal to 20 mm; or it can be that the diameter d of the cyclone 200 and the diameter D of the first cup 100 satisfy d / D≤1 / 2, and the distance between the inner peripheral wall of the first cup 100 and the outer peripheral wall of the cyclone 200 is greater than or equal to 20 mm.

[0088] In this way, the radial distance between the cyclone 200 and the first cup 100 can be increased, which allows the fluid to rotate and separate away from the cyclone 200 under the action of inertia after entering the separation chamber 300. This avoids solids in the fluid clogging the filter screen 230. In addition, it can increase the rotation radius of the fluid, thereby increasing the centrifugal force of the fluid and improving the centrifugal separation effect of the separation chamber 300.
