Description

Technical Field

[0001] This application belongs to the field of vacuum cleaner technology, and particularly relates to a dust collection system, a dust collection station host, and cleaning equipment. Background Technology

[0002] Currently, stick vacuum cleaners typically use hard plastic or non-woven bags as dust containers, which require frequent cleaning, are cumbersome to operate, and are costly.

[0003] Chinese patent CN102309287B discloses a vacuum cleaner with an inlet on both the outer casing of the head assembly and the inner body for connecting to a vacuum cleaner hose. When the vacuum cleaner hose is connected to the inlet on the inner body, a paper bag is used for collecting waste; when the hose is connected to the inlet on the outer casing of the head assembly, a plastic bag is used. Clearly, to accommodate users choosing different types of waste collection accessories (garbage bags) based on their needs, this vacuum cleaner requires two inlets to accommodate different accessories. This results in a complex structure and increased cost. Summary of the Invention

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide a dust collection system, dust collection station host and cleaning equipment that can be interchangeably selected according to different user needs, so as to simplify the structure of the dust collection system, dust collection station host and cleaning equipment, and make the garbage collection operation simple and eliminate the need for frequent cleaning.

[0005] The technical solution adopted in this application embodiment is a dust collection system for use on the dust collection station host of cleaning equipment, the dust collection system comprising:

[0006] A support frame is fixed inside the housing of the dust collection station main unit. The top of the support frame has a through hole for communicating with the dust cup inside the vacuum cleaner main unit of the cleaning equipment. The support frame has an opening on its periphery. A slot is provided on the inner peripheral wall of the support frame near its top, and the slot forms a groove at the opening. A non-woven bag has a bag support at its opening. The bag support can be detachably inserted into the slot to fix the non-woven bag to the support frame, and the bag opening is connected to the through hole. A PE bag assembly includes a housing, a PE bag, and a separator arranged sequentially from the outside to the inside. The separator seals and fixes the opening of the PE bag to the opening of the housing. The separator has an inlet and an outlet. When the PE bag assembly is placed in the support frame through the opening, the inlet of the separator is sealed and connected to the through hole, and the outlet of the separator is connected to a first air outlet channel inside the housing, so that the waste in the dust cup enters the PE bag through the separator, and at the same time, the air entering through the inlet of the separator enters the first air outlet channel through the outlet of the separator.

[0007] In an optional embodiment, the PE bag assembly further includes a guide tube. The guide tube has open ends and is fitted over the separator. The periphery of the upper open end of the guide tube is sealed to the opening of the housing. An inner annular cavity is formed between the guide tube and the separator, and an outer annular cavity is formed between the guide tube and the PE bag. When the suction motor of the cleaning device starts, the waste in the dust cup enters the PE bag through the separator. Air flows out from the lower end of the separator and enters the inner and outer annular cavities respectively, and then enters the first air outlet channel communicating with the outside through the top periphery of the separator. The air flowing out from the lower end of the separator also pushes the bottom of the PE bag to unfold before entering the outer annular cavity, causing it to adhere to the inner wall of the housing. By setting the guide tube, the air entering the PE bag can be diverted, not only unfolding the bottom of the PE bag to collect waste, but also allowing air to smoothly exit the PE bag.

[0008] In an optional embodiment, the periphery of the upper opening of the guide tube extends outward to form a flange, the flange rests on the upper surface of the box opening, and the flange is provided with an air passage hole; The separator includes a tube and a disc. The disc is fitted onto the upper end of the tube, and the bottom of the disc is covered with vent holes that communicate with the air passage holes, so that the outer annular cavity is connected to the first air outlet channel. The bottom periphery of the disc tightly presses the flange against the upper end face of the box opening. This separator, with its special structural design, can not only guide air and waste into the PE bag but also exhaust air to the first air outlet channel.

[0009] In an optional embodiment, the lower end of the guide tube is located below the lower end of the separator's tube body, and the lower end of the guide tube and the lower end of the housing have a predetermined distance; and / or The guide tube is a frustum-shaped structure that gradually tapers from its upper end to its lower end; the bottom end of the separator tube gradually expands downward and outward to form a cone shape.

[0010] In an optional embodiment, the PE bag assembly further includes a fixing frame; The outer periphery of the disc extends upward to form a cavity, and a filter assembly is provided inside the cavity. The fixing bracket is installed above the filter assembly and presses the filter assembly tightly against the cavity wall. By fixing the filter assembly inside the cavity of the disc, the air flowing out from the inner and outer annular cavities is filtered by the filter assembly and then enters the first air outlet channel for discharge, reducing environmental pollution.

[0011] In an optional embodiment, the fixing frame includes an annular frame, a short tube, and multiple connecting rods. The annular frame is adapted to the shape of the inner peripheral wall of the cavity. The short tube is located in the middle of the annular frame, and the multiple connecting rods are used to connect the annular frame and the short tube. The short tube is sleeved on the upper end of the tube body, and a sealing silicone sleeve is provided at the upper end of the short tube. When the PE bag assembly is placed in the support frame, the top side of the sealing silicone sleeve is tightly fitted to the bottom periphery of the through hole. The fixing frame has a reasonable structure, which can achieve a sealed connection with the through hole without obstructing the passage of air.

[0012] A dust collection station host is used on a cleaning device, the cleaning device including a vacuum cleaner host, the vacuum cleaner host including a dust cup, the dust collection station host is provided with a dust collection system as described in any of the above embodiments, the dust collection system being used to collect the waste stored in the dust cup.

[0013] In an optional embodiment, a first air outlet channel is formed between the inner wall of the housing and the outer wall of the support frame; when the PE bag assembly is placed inside the support frame, a second air outlet channel is formed between the outer wall of the PE bag assembly and the inner wall of the support frame; when the dust collection system collects dust and the suction motor of the cleaning equipment is started, the suction motor draws air from the dust cup into the PE bag assembly, the second air outlet channel, and the first air outlet channel in sequence, and discharges it from the dust collection outlet of the dust collection station main unit. The second air outlet channel formed between the outer wall of the housing and the inner wall of the support frame connects the first air outlet channel and the air outlet of the PE bag assembly, allowing for smooth airflow and facilitating the normal operation of the dust collection process.

[0014] In an optional embodiment, the bottom of the housing is provided with an air outlet bracket grille and a support on the air outlet bracket grille; the air outlet bracket grille is used to connect the first air outlet channel and the second air outlet channel; When the PE bag assembly is placed inside the support frame, the bottom of the PE bag assembly's housing is supported on the support. This connects the first and second air outlet channels, facilitating airflow.

[0015] A cleaning device includes a vacuum cleaner main unit, and the cleaning device further includes a dust collection station main unit as described in any of the above embodiments. The vacuum cleaner main unit can be disposed on the dust collection station main unit so that the dust collection system of the dust collection station main unit can collect the garbage sucked in by the dust cup of the vacuum cleaner main unit.

[0016] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: When collecting dust, this application can use either non-woven bags or PE bag components.

[0041] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0042] This application provides a dust collection system for use on cleaning equipment. The cleaning equipment may include a vacuum cleaner main unit 4 and a dust collection station main unit 5. The dust collection system is specifically used on the dust collection station main unit 5 of the cleaning equipment.

[0043] like Figures 1 to 15 As shown, the dust collection system of this embodiment includes a support frame 1, a non-woven bag 2, and a PE bag assembly 3 (Polyethylene, abbreviated as PE). The support frame 1 is fixed inside the housing 51 of the dust collection station main unit 5. The top of the support frame 1 is provided with a through hole 11, which is used to communicate with the dust cup 41 inside the vacuum cleaner main unit 4 of the cleaning equipment. The periphery of the support frame 1 has an opening, and the housing 51 is provided with a movable door 56 corresponding to the opening for opening or closing the opening. The inner peripheral wall of the support frame 1 near its top is provided with a slot, which forms a groove at the opening. The nonwoven bag 2 has a bag support 22 at its opening. The bag support 22 can be detachably inserted into the slot to fix the nonwoven bag 2 to the support frame 1. When the nonwoven bag is fixed to the support frame 1, its opening is connected to the through hole 11, so that the garbage in the dust cup 41 enters the nonwoven bag 2 through the through hole 11 and the opening. Air passes through the nonwoven bag 2 and enters the first air outlet channel 52 inside the housing 51. The PE bag assembly 3 includes a box 31, a PE bag 32 (Polyethylene Bag, hereinafter referred to as PE bag 32), and a separator 33 arranged sequentially from the outside to the inside. The separator 33 seals and fixes the opening of the PE bag 32 to the opening of the box 31. The separator 33 has an inlet and an outlet. When the PE bag assembly 3 is placed in the support frame 1 through the opening, the inlet of the separator 33 is sealed and connected to the through hole 11, and the outlet of the separator 33 is connected to the first air outlet channel 52 in the housing 51, so that the garbage in the dust cup 41 enters the PE bag 32 through the separator 33, and at the same time, the air entering through the inlet of the separator 33 enters the first air outlet channel 52 through the outlet of the separator 33.

[0044] The dust collection system of this application embodiment uses a specially structured PE bag assembly 3, which can be used interchangeably with the non-woven bag 2 in the dust collection system. Since the PE bag 32 is a disposable item, it is set in the box 31 and can be replaced and discarded at any time without frequent cleaning. It is easy to operate and has no secondary pollution.

[0045] In some embodiments, such as Figure 5 As shown, the nonwoven bag 2 includes a bag body 21 and a bag support 22. The bag support 22 is generally plate-shaped. The bag body 21 has a bag opening, and the periphery of the bag opening is fixed to the outer periphery of the bag support 22, forming a shape as shown. Figure 5 The structure is shown. The bag support 22 has a hole 221 in the middle, which communicates with the inside of the bag body 21 through the bag opening. When the bag support 22 of the non-woven bag 2 is inserted into the slot of the support frame 1, the hole 221 on the bag support 22 aligns with the through hole 11 on the support frame 1. (See attached diagram) Figure 2 In this way, the through hole 11 is connected to the bag opening, and then to the bag body 21, so that the garbage in the dust cup 41 can enter the bag body 21 and be collected.

[0046] Furthermore, such as Figure 2 As shown, the top surface of the bag support 22 is provided with sealing cotton 23. The sealing cotton 23 is arranged around the outer periphery of the hole 221. When the bag support 22 is inserted into the slot of the support frame 1, the upper side of the sealing cotton 23 abuts against the lower side of the top wall of the support frame 1 and surrounds the outer periphery of the through hole 11 to seal the support frame 1 and the bag support 22, so as to prevent dust from leaking from the gap between the support frame 1 and the bag support 22 during the process of dust entering the bag body 21 from the dust cup 41.

[0047] The slot in the support frame 1 can be formed, for example, by directly creating an opening in the support frame 1, or by adding a component with a slot to the support frame 1. The embodiment of this application shows a slot bracket 13 embedded in the support frame 1, with the slot disposed on the slot bracket 13. For example... Figure 2 and Figure 6 As shown, the inner peripheral wall of the support frame 1 has a groove 12 near its top, and the groove 12 forms two slots at the opening of the support frame 1. Figure 7 and Figure 8 As shown, the outer contour of the slot bracket 13 is adapted to the shape of the inner peripheral wall of the support frame 1. In this embodiment, the support frame 1 is roughly rectangular in shape, with one side completely open to form an opening, and its bottom completely open to form an opening, so that the support frame 1 is surrounded by three sides and a top surface. The slot bracket 13 has a U-shaped structure. The inner sides of the two U-shaped arms opposite each other are provided with guide grooves 131, which respectively extend to the free ends of the two U-shaped arms to form slots. The slot bracket 13 is positioned with its U-shaped bottom facing the support frame 1, so that the two U-shaped arms are pushed into the two slots of the groove 12 on the support frame 1, thus installing the slot bracket 13 on the support frame 1, so that the support frame 1 has a slot near its top. See Figure 6 When it is necessary to use the non-woven bag 2 to collect garbage, the two opposite sides of the bag bracket 22 are respectively aligned with the slots of the two guide slots 131 on the slot bracket 13 and pushed inward, so that the bag bracket 22 can be installed on the slot bracket 13, and then the non-woven bag 2 can be fixed on the support frame 1.

[0048] In some embodiments, such as Figures 9 to 12As shown, the PE bag assembly 3, in addition to the housing 31, PE bag 32, and separator 33, further includes a guide tube 34. The guide tube 34 has open ends and is fitted over the separator 33. The periphery of the upper open end of the guide tube 34 is sealed to the opening of the housing 31. An inner annular cavity 35 is formed between the guide tube 34 and the separator 33, and an outer annular cavity 36 is formed between the guide tube 34 and the PE bag 32. When dust collection is required, the suction motor of the cleaning equipment starts, and the debris in the dust cup 41 enters the PE bag 32 through the separator 33. Air flows out from the lower end of the separator 33 and enters the inner annular cavity 35 and the outer annular cavity 36 respectively, and then enters the first air outlet channel 52, which communicates with the outside, from the top outer periphery of the separator 33. (See [reference]). Figure 13 Furthermore, the air flowing out from the lower end of the separator 33 is used to push the bottom of the PE bag 32 to unfold before entering the outer annular cavity 36, causing it to adhere to the inner wall of the housing 31. By providing the guide tube 34, the air flowing out from the lower end of the separator 33 can be divided into two streams. The first stream flows upward along the inner annular cavity 35 and finally enters the first air outlet channel 52 from the top outer periphery of the separator 33 for external discharge. The second stream forms a downward and outward airflow, pushing the bottom of the PE bag 32 to unfold and adhere to the inner wall of the housing 31 (see...). Figure 13 (Red arrow in the middle) to facilitate garbage collection. The second stream of air finally flows upward along the outer annular cavity 36 and enters the first air outlet channel 52 from the top outer periphery of the separator 33 for external discharge.

[0049] In this embodiment of the application, the PE bag assembly 3, when the PE bag 32 is airtight, utilizes the clever cooperation between the separator 33 and the guide tube 34 to change the airflow path, which can keep the soft PE bag 32 in an unfolded state and allow air to flow smoothly into the first air outlet channel 52, thus ensuring the smooth progress of garbage collection.

[0050] Furthermore, continue to combine Figure 11 The upper opening of the guide tube 34 extends outward to form a flange 341, which rests on the upper surface of the box opening. An air passage 3411 is provided on the flange 341.

[0051] like Figure 12As shown, the separator 33 includes a tube 331 and a disc 332. The disc 332 is fitted onto the upper end of the tube 331, meaning the upper end of the tube 331 passes through the disc 332 and is located above it. The upper end of the tube 331 communicates with the through hole 11 on the support frame 1, and the lower end of the tube 331 forms an outlet for waste and air. The bottom of the disc 332 is covered with vent holes 3321, which communicate with the air passage holes 3411, so that the outer annular cavity 36 communicates with the first air outlet channel 52. The inner annular cavity 35 communicates directly with the vent holes 3321. The periphery of the bottom surface of the disc 332 presses the flange 341 tightly against the upper surface of the box opening. Waste and air are introduced through the tube 331 of the separator 33, and the air vent 3321 on the disc 332 of the separator 33 is connected to the air passage 3411 on the flange 341 of the guide tube 34, so that the air entering the outer annular cavity 36 passes through the air passage 3411 and the air vent 3321 in sequence, and then enters the first air outlet channel 52.

[0052] like Figure 11 As shown, sealing cotton 37 is provided between the flange 341 of the guide tube 34 and the upper end face of the box opening of the box body 31, and between the periphery of the bottom surface of the disc body 332 and the upper surface of the flange 341 of the guide tube 34, to ensure sealing and prevent dust leakage.

[0053] In some embodiments, such as Figure 10 As shown, the lower end of the guide tube 34 is located below the lower end of the tube body 331 of the separator 33, and there is a preset distance between the lower end of the guide tube 34 and the lower end of the box body 31 (i.e., the bottom of the PE bag 32). This creates a "low-pressure buffer zone and settling space" at the bottom of the box body 31 (the bottom of the PE bag 32), guiding air upwards and forcing the waste to sink. A second stream of air escapes from this distance between the lower end of the guide tube 34 and the bottom of the box (bag bottom), enters the outer annular cavity 36, and then flows upwards along the inner wall of the box body 31 (the inner wall of the PE bag 32) and enters the first air outlet channel 52 through the air passage 3411 and the vent 3321. The waste carried by the air falls downwards into the bottom space of the PE bag 32 due to its own gravity. That is, the airflow "turns upwards" from the distance, without strongly scouring the waste that has already settled at the bottom of the bag, thus avoiding secondary entrainment.

[0054] Continue to combine Figure 10The guide tube 34 is a frustum-shaped structure that gradually tapers from its upper end to its lower end. This causes the air entering the guide tube 34 to slow down continuously as it flows upward, gradually reducing its ability to carry particles (such as dust). The dust separates from the rising airflow under its own weight and falls into the PE bag 32, thus achieving separation. The bottom end of the separator 33's tube 331 gradually expands downward and outward to form a cone shape. Designing the bottom end of the tube 331 as a cone shape can rapidly slow down the waste, creating a settling zone and preventing secondary re-entrainment.

[0055] In some embodiments, such as Figure 9 , Figure 10 , Figure 12 and Figure 13 As shown, the PE bag assembly 3 also includes a fixing frame 38. The outer periphery of the disc body 332 extends upward to form a cavity 3322, and a filter assembly 39 is disposed within the cavity 3322. The fixing frame 38 is positioned above the filter assembly 39 and presses the filter assembly 39 against the cavity wall of the cavity 3322. By fixing the filter assembly 39 within the cavity 3322 of the disc body 332 using the fixing frame 38, the air flowing out from the inner annular cavity 35 and the outer annular cavity 36 is filtered by the filter assembly 39 and then discharged through the first air outlet channel 52, reducing environmental pollution.

[0056] like Figure 11 and Figure 12 As shown, the filter assembly 39 may include a filter sponge and a filter HEPA filter, with the filter sponge located below the filter HEPA filter and the fixing bracket 38 pressing against the top of the filter HEPA filter.

[0057] Continuing with Figure 12, the fixing frame 38 includes an annular frame 381, a short tube 382, ​​and multiple connecting rods 383. The annular frame 381 is adapted to the shape of the inner peripheral wall of the cavity 3322. In this embodiment, the annular frame 381 is approximately rectangular. The short tube 382 is located in the middle of the annular frame 381, and the multiple connecting rods 383 are used to connect the annular frame 381 and the short tube 382; that is, the multiple connecting rods 383 are radially arranged between the outer peripheral wall of the short tube 382 and the outer peripheral wall of the annular frame 381. The short tube 382 is sleeved on the upper end of the tube body 331, and a sealing silicone sleeve 384 is provided at the upper end of the short tube 382. The PE bag assembly 3 is placed inside the support frame 1. When the suction motor is started, the top side of the sealing silicone sleeve 384 is tightly fitted to the bottom periphery of the through hole 11 under the action of suction. See Figure 1. Figure 4 This achieves a sealed connection between the PE bag assembly 3 and the through hole 11 on the support frame 1.

[0058] When it is necessary to use the PE bag assembly 3 to collect garbage, place the PE bag assembly 3 along... Figure 14 and Figure 15As indicated by the middle arrow, the PE bag assembly 3 is pushed into the support frame 1 through the opening. The bottom of the PE bag assembly 3 is supported on the support 55 (which will be described below). The upper end of the short tube 382 of the fixing bracket of the PE bag assembly 3 is aligned with the through hole 11, and the sealing silicone sleeve 384 is fitted against the bottom periphery of the through hole 11, forming a shape as shown by the arrow. Figure 4 The state shown.

[0059] This application embodiment also provides a dust collection station host 5, which is used on cleaning equipment, such as... Figures 16 to 18 As shown, the cleaning equipment includes a vacuum cleaner main unit 4 and a dust collection station main unit 5. The vacuum cleaner main unit 4 includes a dust cup 41. The dust collection station main unit 5 is equipped with a dust collection system as described in any of the above embodiments, which is used to collect the waste stored in the dust cup 41. In this embodiment, the dust collection station main unit 5 includes a dust collection system that can replace the non-woven bag 2 and the PE bag assembly 3, allowing the dust collection station main unit 5 to use the PE bag assembly 3 for dust collection. After dust collection, the PE bag 32 of the PE bag assembly 3 can be replaced and discarded at any time. Compared to the traditional dust collection method that can only use the non-woven bag 2 or hard plastic as the dust collection container, this avoids the problems of frequent cleaning and cumbersome operation, reducing cleaning time by more than 30% and cost by more than 5 times.

[0060] In some embodiments, such as Figure 18 As shown, a first air outlet channel 52 is formed between the inner wall of the housing 51 and the outer wall of the support frame 1. When the PE bag assembly 3 is placed inside the support frame 1, a second air outlet channel 53 is formed between the outer wall of the housing 31 of the PE bag assembly 3 and the inner wall of the support frame 1. When the dust collection system collects dust and the suction motor of the cleaning equipment starts, the debris in the dust cup 41 is collected at the bottom of the PE bag 32. After being filtered by the filter assembly 39 of the PE bag assembly 3, the air first enters the first air outlet channel 52, then enters the second air outlet channel 53, and is then discharged to the outside through the dust collection outlet 57 of the dust collection station main unit 5. The second air outlet channel 53 formed between the outer wall of the housing 31 and the inner wall of the support frame 1 connects the first air outlet channel 52 and the air outlet of the PE bag assembly 3 (the vent 3321 of the separator 33 actually forms the air outlet of the PE bag assembly 3), allowing the air to flow smoothly and facilitating the normal operation of the dust collection work.

[0061] like Figure 19 As shown, the bottom of the housing 51 is provided with an air outlet bracket grille 54 and a support 55 supported on the air outlet bracket grille 54. The air outlet bracket grille 54 is used to connect the first air outlet channel 52 and the second air outlet channel 53. In this way, the first air outlet channel 52 and the second air outlet channel 53 are connected, which facilitates the passage of air. Figure 19 The direction of the middle arrow indicates the direction of airflow.

[0062] When the PE bag assembly 3 is placed inside the support frame 1, the bottom of the housing 31 of the PE bag assembly 3 is supported on the support 55. The support 55 keeps the PE bag assembly 3 stably within the support frame 1.

[0063] like Figures 16 to 18 As shown, this application embodiment also provides a cleaning device, which includes a vacuum cleaner main unit 4 and a dust collection station main unit 5. The vacuum cleaner main unit 4 can be installed on the dust collection station main unit 5 so that the dust collection system of the dust collection station main unit 5 can collect the garbage sucked in by the dust cup 41 of the vacuum cleaner main unit 4.

[0064] like Figure 17 As shown, the vacuum cleaner main unit 4 can be removed from the dust collection station main unit 5 to clean surfaces such as the floor. Debris on the floor is sucked into the dust cup 41 of the vacuum cleaner main unit 4 via a roller brush. When the dust cup 41 contains a certain amount of debris and needs to be collected, such as... Figure 16 As shown, the vacuum cleaner main unit 4 is hung on the top of the dust collection station main unit 5. The protrusion on the dust collection station main unit 5 pushes the dust collection gate 42 on the vacuum cleaner main unit 4 to open and connect with the dust collection air outlet 57 of the dust collection station main unit 5. The lower cover 411 of the dust cup 41 connects with the dust collection tray 43. The lower port of the dust collection tray 43 connects with the through hole 11 (that is, the dust cup 41 is connected to the through hole 11 on the support frame 1 through the dust collection tray 43), so that the garbage in the dust cup 41 can enter the PE bag assembly 3 or the non-woven bag 2 under the action of dust collection power.

[0065] The dust collection power can be provided by the suction motor on the dust collection station main unit 5 or the suction motor in the vacuum cleaner main unit 4. When the suction motor is powered on, the first air outlet channel 52 and the second air outlet channel 53 (the second air outlet channel 53 is only available when using the PE bag assembly 3) generate a vacuum to form a negative pressure. The lower cover 411 of the dust cup 41 in the vacuum cleaner main unit 4 opens, and the garbage can enter the PE bag assembly 3 or the non-woven bag 2 through the dust collection tray 43. The garbage is collected at the bottom of the bag.

[0066] like Figure 18 As shown, when the suction motor is powered on, air enters from the air inlet on the roller brush of the vacuum cleaner main unit 4 (this is basically the same as the prior art), passes through the dust cup 41 and the dust collection tray 43 and enters the PE bag assembly 3. In the PE bag assembly 3, it is divided into two streams that flow upward along the inner annular cavity 35 and the outer annular cavity 36 respectively. After passing through the air outlet of the PE bag assembly 3, it enters the second air outlet channel 53, the air outlet bracket grille 54, the first air outlet channel 52 and the dust collection air outlet 57 in sequence, and finally is discharged from the exhaust port 44 of the vacuum cleaner main unit 4 through the dust collection gate 42, thus forming a complete closed dust collection path.

[0067] When the PE bag assembly 3 is removed and replaced with the non-woven bag 2, the second air outlet duct 53 is no longer available. Air enters the non-woven bag 2 through the dust cup 41 and the dust collection tray 43. Since the non-woven bag 2 is breathable, the air passes directly through the non-woven bag 2 and enters the air outlet bracket grille 54, the first air outlet duct 52, and the dust collection outlet 57 in sequence. Finally, it is discharged from the exhaust port 44 of the vacuum cleaner main unit 4 through the dust collection gate 42.

[0068] In this embodiment, the PE bag assembly 3 and the non-woven bag 2 are interchangeable. The PE bag 32 is fitted onto the inner wall of the housing 31 and can be replaced and discarded after dust collection. Compared with traditional dust collection methods, this saves cleaning time and reduces cleaning costs.

[0069] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
