Description

Technical Field

[0001] This invention relates to a vacuum cleaner assembly with a debris retainer for use in vacuum cleaners. Background Technology

[0002] Vacuum cleaners come in a variety of configurations that can be particularly beneficial for different environments. A vacuum cleaner typically includes: a main body with a debris retainer; and a suction wand coupled to the main body and configured to connect to one or more attachments with various nozzle options. During operation, all debris from the nozzles enters and is stored in the debris retainer. As the debris retainer becomes increasingly full, the demand on the suction motor increases. Furthermore, some types of debris may be coarse or space-consuming, requiring frequent emptying of the debris retainer. Summary of the Invention

[0003] According to one aspect of the invention, a suction rod assembly for a vacuum cleaner includes a suction rod having a first end and a second end configured to be connected to the vacuum cleaner. A coarse debris retainer extends between a first debris retainer end connected to the second end of the suction rod and a second debris retainer end configured to be connected to an accessory. The coarse debris retainer defines a chamber having a debris chamber inlet opening and a fine debris chamber outlet opening. A debris separator is located in the chamber between the debris chamber inlet opening and the fine debris chamber outlet opening. A suction channel is formed between the debris chamber inlet opening and the first end of the suction rod.

[0004] According to another aspect of this disclosure, a vacuum cleaner includes a body comprising a suction motor, a handle, and a clean air outlet. A surface treatment base includes a nozzle, and an airflow path extends from the nozzle to the clean air outlet, wherein the suction motor is positioned within the airflow path. A vacuum stick assembly includes a vacuum stick having a first end and a second end configured to be connected to the vacuum cleaner. A coarse debris retainer extends between a first debris retainer end connected to the second end of the vacuum stick and a second debris retainer end opposite to the first debris retainer end and configured to be connected to an accessory. The coarse debris retainer defines a chamber having a debris chamber inlet opening defined by the second debris retainer end and a fine debris chamber outlet opening defined by the first debris retainer end. A debris separator is located within the chamber between the debris chamber inlet opening and the fine debris chamber outlet opening. The debris separator is defined by: a coarse debris holding section located between the debris chamber inlet and the debris separator; and a fine debris directing conveying section located between the fine debris chamber outlet and the debris separator. A suction channel is formed between the debris chamber inlet and the first end of the suction rod.

[0005] According to another aspect of the invention, a suction rod assembly for a vacuum cleaner includes a suction rod having a first end and a second end configured to be connected to the vacuum cleaner. A coarse debris retainer extends between a first debris retainer end connected to the second end of the suction rod and a second debris retainer end movable between an open position and a closed position and defining a cavity. The coarse debris retainer defines a chamber having a debris chamber inlet opening and a fine debris chamber outlet opening. A debris separator is located in the chamber between the debris chamber inlet opening and the fine debris chamber outlet opening. The debris separator includes a cylindrical body defining a fine debris guiding transport section. The cylindrical body extends from the fine debris chamber outlet opening into the chamber to a recess that engages with the cavity. A suction channel is formed between the debris chamber inlet opening and the first end of the suction rod.

[0012] refer to Figures 1 to 6 As shown, reference numeral 10A generally designates a suction stick assembly with a first configuration for a vacuum cleaner 12. The suction stick assembly 10A includes a suction stick 14 having a first end 16 and a second end 18 configured to connect to the vacuum cleaner 12. A coarse debris retainer 20A extends between a first debris retainer end 22 connected (e.g., selectively or permanently) to the second end 18 of the suction stick 14 and a second debris retainer end 24 configured to connect to an accessory 26. The coarse debris retainer 20A defines a chamber 28 having a debris chamber inlet opening 30 and a fine debris chamber outlet opening 32. A debris separator 34A is located within the chamber 28 between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32. A suction channel 36 is formed between the debris chamber inlet opening 30 and the first end 16 of the suction stick 14.

[0013] Continue to refer to Figures 1 to 6 The chamber 28 includes: a coarse debris holding section 38 located between the debris chamber inlet opening 30 and the debris separator 34A; and a fine debris directing conveying section 40 located between the fine debris chamber outlet opening 32 and the debris separator 34A. In use, the vacuum cleaner 12 can be an integral unit and supplied to the consumer together with the vacuum stick assembly 10A; or the vacuum stick assembly 10A can be a separate component that can be used with the vacuum cleaner 12 and supplied to the consumer together with or separately from the vacuum cleaner 12. The vacuum cleaner 12 in... Figure 1It is described as a stick vacuum cleaner. However, it should be understood that other types of vacuum cleaners (such as upright vacuum cleaners, corded vacuum cleaners, canister vacuum cleaners, etc.) can be integrated with the stick assembly 10A according to the same principle described below, or can be connected and used with the stick assembly in other ways.

[0014] Now for specific reference Figure 1 The vacuum cleaner assembly 12 may include a body 42 extending between an upper surface 44 and a lower surface 46. The body 42 may include: a debris retainer 48, a battery 50 and / or a power receiving cable or a module for inserting the power receiving cable; and a drive assembly 52 including a suction motor 54 that draws air through a clean air outlet in the body 42. An airflow path extends between the clean air outlet and a nozzle 56, and the suction motor 54 is positioned within the airflow path. A second end 18 of the vacuum stick assembly 10A may be connected to the body 42 (e.g., the lower surface 46). A second debris retainer end 24 is configured to connect to an attachment 26 having a nozzle 56. The attachment 26 is depicted as a suction base (e.g., having one or more rollers) defining the nozzle 56. However, the attachment 26 may include other types of vacuum cleaner attachments with nozzles of different shapes. The second debris retainer end 24 can be configured to be permanently connected to the accessory 26 (e.g., integrated with the vacuum stick assembly 10A) or selectively connected to the accessory (e.g., via one or more tabs, buttons, claws, or other mechanical connectors). Furthermore, in some embodiments, it should be understood that the debris chamber inlet opening 30 may coexist with the nozzle 56 (e.g., defined by the same structure) or be otherwise defined by the second debris retainer end 24.

[0015] Now for reference Figure 2During operation, debris 58 travels along the airflow path. More specifically, debris 58 enters the airflow path from the surface, passes through the suction nozzle 56 and the debris chamber inlet 30, and enters the chamber 28, where it is separated into finer debris 58A and coarser debris 58B by the debris separator 34A. More specifically, the finer debris 58A travels through the debris separator 34A and enters the fine debris conduit section 40, while the coarser debris 58B is contained in the coarse debris holding section 38 and prevented from entering the fine debris conduit section 40 by the debris separator 34A. On the other hand, the finer debris 58A continues to travel through the fine debris chamber outlet 32, the suction rod 14, and enters the fine debris holder 48. In this way, the fine debris retainer 48 primarily receives only finer debris 58A, and the usage time of the vacuum cleaner 12 can be extended between the need to empty the finer debris 58A from the fine debris retainer 48. Furthermore, separating the finer debris 58A from the coarser debris 58B facilitates the classification of debris 58 by size; for example, in the case where an unintended object is accidentally vacuumed through the nozzle 56, it is easier to remove the object based on its size.

[0016] In some embodiments, the vacuum stick assembly 10A may include one or more conductive members 60 (e.g., wires) extending, for example, between a first end 16 of the vacuum stick 14 and a second debris retainer end 24. Thus, in some embodiments, the first end 16 of the vacuum stick 14 may include one or more conductive contacts that interface with contacts on the body 42 of the vacuum cleaner 12, and the second debris retainer end 24 may also include one or more conductive contacts that interface with contacts on the attachment 26. In this way, when the attachment 26 requires power from the battery 50, a power receiving line, and / or a power receiving module, current, commands (e.g., via a user interface), etc., can be transmitted through the vacuum stick assembly 10A. In some embodiments, the vacuum stick assembly 10A may include a plunger 62 comprising a body portion 64 and a plunger portion 66. The plunger portion 66 may define an orifice 68 aligned with the debris chamber inlet opening 30. The body portion 64 may be slidable in a track or otherwise removable from the chamber 28. In some embodiments, the chamber inlet 30 may include a door 67 that opens and closes based on suction force. For example, door 67 may include a flexible membrane that deforms and rises into the chamber 28 when exposed to suction force. Although Figure 2 The vacuum cleaner assembly 10A is schematically depicted, but it should be understood that, unless otherwise explicitly stated, similar operating principles, functions, components, sizes, and combinations as those of vacuum cleaners and accessories can be applied to other constructions. For the sake of brevity, descriptions of these constructions can refer back to the reference. Figure 2 .

[0017] Now for reference Figure 3 and Figure 4 The coarse debris retainer 20A with a first configuration includes a sidewall 70A (e.g., a cylindrical sidewall 70A) extending between a first debris retainer end 22 and a second debris retainer end 24. The debris separator 34A with the first configuration also includes a cylindrical body 72A defining a fine debris guiding transport section 40 (e.g., inside the cylindrical body 72A). The cylindrical body 72A may be at least partially (e.g., a few, most, or substantially all) formed of a filter 74, such as a mesh filter. More specifically, a fine debris chamber outlet opening 32 may be defined by the first debris retainer end 22 and the cylindrical body 72A. The debris separator 34A may include a rigid frame 76A extending from the fine debris chamber outlet opening 32 to the second debris retainer end 24. The rigid frame 76A may include a plurality of openings 78, and the filter 74 may be located in the openings 78. The opening 78 can occupy a large portion of the surface area of ​​the debris separator 34A (e.g., it can circumferentially surround the cylindrical body 72A). Generally, the surface area and type of the filter 74 between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32 can affect the suction loss between the suction motor 54 and the nozzle 56. Therefore, in the first configuration, the large surface area of ​​the filter 74 can have a minimal impact on the suction force. In some embodiments, the cylindrical body 72A is centrally located within the chamber 28 (e.g., along a common axis defining the center of the cylindrical body 72A and the cylindrical sidewall 70A).

[0018] Filter 74 may include a mesh with openings sized to prevent coarser debris 58B from passing through while allowing finer debris 58A to pass through. For example, filter 74 may include diamond, square, circular, or other shaped openings. For example, the openings may be about 2 mm or smaller, such as between about 0.1 mm and about 2 mm, between about 0.5 mm and about 1.5 mm, or about 1 mm. Other filters used in other configurations, as described below, may have similar sizes and dimensions to the filter described with reference to the first configuration.

[0019] like Figure 4 and Figure 5As depicted, the second debris retainer end 24 defines a cavity 80 that receives a rigid frame 76A. More specifically, the rigid frame 76A can extend from the first debris retainer end 22 to an end 82 that defines a recess 84 that mates precisely with the cavity 80. The connection between the rigid frame 76A and the cavity 80 can resist forces that could cause buckling between the vacuum cleaner stick 14 and the coarse debris retainer 20A. In some embodiments, one or more conductive members 60 (e.g., wires) can extend through or otherwise onto the rigid frame 76A, and conductive contacts for attachment 26 can be located on the end 82 (e.g., the recess 84). Thus, some attachments may not be energized unless the recess 84 is in the cavity 80. A debris chamber inlet opening 30 is defined by the second debris retainer end 24 and can be radially located between the cylindrical sidewall 70A of the debris retainer 20A and the cylindrical body 72A of the debris separator 34A. The second debris retainer end 24 may include an accessory connector 85 extending from the outside of the second debris retainer end 24. Thus, the accessory connector 85 can be used as a suction nozzle 56 for various purposes. The accessory connector 85 may include one or more tabs, buttons, claws, or other mechanical connectors for attachment to an accessory.

[0020] Now for reference Figure 5 and Figure 6 The second debris retainer end 24 may be movable relative to the sidewall 70A of the coarse debris retainer 20A between a closed position and an open position. In the closed position, the chamber 28 is closed between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32. In the open position, the chamber 28 is opened to remove the debris 58 contained within the chamber 28. For example, the second debris retainer end 24 may pivot relative to the sidewall 70A via a pivot linkage mechanism 86. The second debris retainer end 24 may also include a releasable hook 88 for securing the second debris retainer end 24 to the sidewall 70A.

[0021] The cylindrical body 72A of the debris separator 34A may include a locked position and an unlocked position. In the unlocked position, the cylindrical body 72A can be at least partially removed from the chamber 28 to remove coarser debris 58B. More specifically, a first debris retainer end 22 may define a fine debris chamber outlet opening 32, and the debris separator 34A may be slidable within the fine debris chamber outlet opening 32. The first debris retainer end 22 may include an outer lip 90 surrounding the outer surface of the sidewall 70A and a cup-shaped portion 92 extending into a region inside the sidewall 70A. The first debris retainer end 22 may define a guide sidewall 94 extending around the fine debris chamber outlet opening 32. The guide sidewall 94 may extend from the cup-shaped portion 92 toward the suction rod 14 and is substantially flush with the end of the sidewall 70A. In some embodiments, the guide sidewall 94 may be cylindrical to receive the cylindrical body 72A. In some embodiments, another area of ​​the guide sidewall 94 or the coarse debris retainer 20A near the fine debris chamber outlet opening 32 includes an agitator, such as a plurality of bristles 95. Figure 4 Multiple bristles 95 surround the fine debris chamber output opening 32 to remove debris 58 from it when the debris separator 34A is at least partially removed. Figure 6 As best depicted, the debris separator 34A is coupled to the vacuum cleaner stick 14 and is rotatable relative to the first debris retainer end 22 to obtain an unlocked position. More specifically, the guide sidewall 94 may include a protrusion 96, and the rigid frame 76A may include a track 98 that engages with the protrusion 96 into a locked position when the rigid frame 76A and the guide sidewall 94 rotate relative to each other. In the depicted implementation, the second end 18 of the vacuum cleaner stick 14 is connected to the debris separator 34A. Therefore, in the unlocked position, the vacuum cleaner stick 14 and the debris separator 34A can be pulled out relative to the sidewall 70A.

[0022] Now for reference Figures 7 to 9The image depicts a vacuum cleaner assembly 10B with a second configuration. Unless otherwise explicitly stated, the vacuum cleaner assembly 10B with the second configuration may include all the same operating principles, functions, elements, sizes, and combinations as vacuum cleaners and accessories with other configurations (including the previously described first configuration). Based on the similarity between the first and second configurations, similar elements will be designated with the same reference numerals. Similar to the first configuration, the second configuration may include a vacuum cleaner 14 having a first end 16 and a second end 18 configured to connect to a vacuum cleaner 12. A coarse debris retainer 20B may extend between a first debris retainer end 22 connected (e.g., selectively or permanently) to the second end 18 of the vacuum cleaner 14 and a second debris retainer end 24 configured to connect to one of the accessories 26 previously described. The coarse debris retainer 20B defines a chamber 28 having a debris chamber inlet opening 30 and a fine debris chamber outlet opening 32. The debris separator 34B is located in chamber 28 between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32. A suction channel 36 is formed between the debris chamber inlet opening 30 and the first end 16 of the suction rod 14.

[0023] The coarse debris retainer 20B with a second configuration includes sidewalls 70B (e.g., symmetrical sidewalls) extending between the first debris retainer end 22 and the second debris retainer end 24. The debris separator 34B with a second configuration includes a body 72B defining the boundary between the coarse debris holding section 38 and the fine debris guiding conveying section 40. The body 72B may be at least partially (e.g., a few, most, or substantially all) formed of a filter 74, such as a mesh filter as previously described. More specifically, the fine debris chamber outlet opening 32 may be defined by the first debris retainer end 22, the body 72B, and the sidewalls 70B. The debris separator 34B may include a rigid frame 76B extending from the second debris retainer end 24 toward the first debris retainer end 22. The rigid frame 76B may include a coarse debris venting side 100 defining a debris venting window 102 and a filter side 104 defining a plurality of openings 78, with a filter 74 located within the openings 78. The openings 78 may occupy a large portion of the surface area of ​​the filter side 104 of the debris separator 34B. Generally, the surface area of ​​the filter 74 between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32 can be smaller than in the first configuration. However, this results in a reduction in overall size and an improved form factor for the coarse debris retainer 20B.

[0024] Now for specific reference Figure 8 and Figure 9Similar to the first configuration, the body 72B of the debris separator 34B includes an unlocked position in which the body 72B can be at least partially removed from the chamber 28 to remove debris 58. More specifically, the debris separator 34B is coupled to a second debris retainer end 24, and the second debris retainer end 24 has a cap-like shape that can be removed together with the debris separator 34B from the coarse debris retainer 20B to remove debris 58. In some embodiments, the debris separator 34B includes a cup-shaped end 106 adjacent to the first debris retainer end 22 to pull coarser debris 58B from the coarse debris retainer 20B. The second debris retainer end 24 may include one or more tabs, buttons, claws, tracks, and protrusions or other mechanical connectors that couple the second debris retainer end 24 to the sidewall 70B in a locked position and can be released in an unlocked position. The second debris retainer end 24 may also include an accessory connector 85 extending from the outside of the second debris retainer end 24. Thus, the accessory connector 85 can be used as a suction nozzle 56 for various purposes. The accessory connector 85 may include one or more tabs, buttons, claws, or other mechanical connectors for attachment to an accessory.

[0025] Similar to the first embodiment, the second debris retainer end 24 may form a cavity 80 that accommodates a rigid frame 76B (e.g., cup-shaped end 106) to resist forces that could cause buckling between the vacuum cleaner stick 14 and the coarse debris retainer 20A. In some embodiments, one or more conductive members 60 (e.g., wires) may extend through or otherwise onto the rigid frame 76B, and conductive contacts for attachment 26 may be located on the cup-shaped end 106. Thus, some attachments may not be energized unless the cup-shaped end 106 is in the cavity 80.

[0026] Now for reference Figures 10 to 12The image depicts a vacuum cleaner stick assembly 10C with a third configuration. Unless otherwise explicitly stated, the vacuum cleaner stick assembly 10C with the third configuration may include all the same operating principles, functions, elements, sizes, and combinations as vacuum cleaners and accessories with other configurations (including the previously described first and second configurations). Based on the similarity between the first, second, and second configurations, similar elements are designated with the same reference numerals. More specifically, the vacuum cleaner stick assembly 10C includes a vacuum cleaner stick 14 having a first end 16 and a second end 18 configured to connect to a vacuum cleaner 12. A coarse debris retainer 20C extends between a first debris retainer end 22 connected (e.g., selectively or permanently) to the second end 18 of the vacuum cleaner stick 14 and a second debris retainer end 24 opposite to the first debris retainer end 22 and configured to connect to one of the accessories 26 previously described. The coarse debris retainer 20C defines a chamber 28 having a debris chamber inlet opening 30 and a fine debris chamber outlet opening 32. The debris separator 34C is configured to perform cyclonic filtration within chamber 28 between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32. A suction channel 36 is formed between the debris chamber inlet opening 30 and the first end 16 of the suction rod 14.

[0027] The coarse debris retainer 20C with a third configuration includes a sidewall 70C (e.g., a cylindrical sidewall) extending between the first debris retainer end 22 and the second debris retainer end 24. The debris separator 34C with a third configuration includes a body 72C (e.g., a cup-shaped body) defining the boundary between the coarse debris holding section 38 and the fine debris guiding delivery section 40. More specifically, the body 72C may extend beyond the debris chamber inlet opening 30 and define the fine debris guiding delivery section 40. The debris chamber inlet opening 30 and the fine debris chamber outlet opening 32 may be positioned close to the first debris retainer end 22, and a flexible suction tube 108 extends from the debris chamber inlet opening 30 to an accessory connector 85 outside the chamber 28, which may extend from the second debris retainer end 24. In some embodiments, the flexible suction tube 108 may be selectively released from the accessory connector 85. Thus, the accessory connector 85 or the flexible suction tube 108 can be used as a suction nozzle 56 for various benefits. In some embodiments, one or more conductive members 60 (e.g., wires) may extend through or otherwise onto the flexible suction tube 108, and conductive contacts for the accessory 26 may be located on the accessory connector 85. Thus, some accessories may not be energized unless the flexible suction tube 108 is in the accessory connector 85.

[0028] The body 72C may be at least partially (e.g., a few, most, or substantially all) formed by a filter 74, such as a mesh filter as previously described. More specifically, the fine debris chamber outlet opening 32 may be defined by a first debris retainer end 22 and a sidewall 70C. The debris separator 34C may include a rigid frame 76C extending from the first debris retainer end 22. The rigid frame 76C may define a plurality of openings 78, and the filter 74 may be located in the openings 78. The openings 78 may occupy a large portion of the surface area of ​​the debris separator 34C. Generally, the surface area of ​​the filter 74 between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32 may be smaller than in the first configuration, but larger than in the second configuration. However, this achieves a balance between suction loss and improved form factor.

[0029] Now for reference Figure 11 and Figure 12 The debris chamber inlet 30 may include an inlet guide tube 110, which is connected to the flexible suction tube 108 opposite to the accessory connector 85. The inlet guide tube 110 may terminate at the debris chamber inlet 30. The cyclone wall 112 may be defined by the inner surface 114 of the side wall 70C, the inner surface 116 of the inlet guide tube 110, or a combination of the inner surface 114 of the side wall 70C and the inner surface 116 of the inlet guide tube 110. More specifically, as Figure 12 As best shown, the inner surface 116 of the input guide tube 110 may be oriented toward and merge with the inner surface 114 of the sidewall 70C. Since the sidewall 70C is cylindrical, the inner surface 114 is generally circular in cross-section. The inner surface 116 of the input guide tube 110 may be angled to intersect and merge with the circumferential direction of the inner surface 114 of the sidewall 70C. Thus, debris 58 entering the input guide tube 110 is guided in the circumferential direction of the inner surface 114 of the sidewall 70C and then exits the debris chamber input opening 30. Therefore, the cyclone filter causes coarser debris 58B to travel circumferentially within the chamber 28 and then settle toward the second debris retainer end 24, while finer debris 58A enters through the filter 74 and proceeds parallel to the fine debris chamber output opening 32. In some embodiments, the rigid frame 76C includes a solid base 115 opposite to the rigid frame 76C and aligned with the fine debris chamber output opening 32. Thus, the suction force is typically directed (e.g., directly aligned with the debris chamber inlet 30) toward the side of the debris separator 34C.

[0030] In some embodiments, one or both of the first debris retainer end 22 and the second debris retainer end 24 may be movable relative to the sidewall 70C of the coarse debris retainer 20C between a closed position and an open position. In the closed position, the chamber 28 is closed between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32. In the open position, the chamber 28 is opened to remove the debris 58 contained within the chamber 28. For example, the first debris retainer end 22 and / or the second debris retainer end 24 may be pivotable relative to the sidewall 70C via a pivot linkage mechanism 86 (e.g., the second debris retainer end 24), or may be removable via one or more tabs, buttons, latches, or other mechanical connectors (e.g., the first debris retainer end 22). For example, the first debris retainer end 22 may also include a releasable hook 88 for securing the first debris retainer end 22 to the sidewall 70C.

[0031] Now for reference Figures 13 to 17 The image depicts a vacuum cleaner stick assembly 10D with a fourth configuration. Unless otherwise explicitly stated, the vacuum cleaner stick assembly 10D with the fourth configuration may include all the same operating principles, functions, elements, sizes, and combinations as vacuum cleaners and accessories with other configurations (including the previously described first configuration). Based on the similarity between the configurations, similar elements will be designated with the same reference numerals. Similar to other configurations, the fourth configuration may include a vacuum cleaner stick 14 having a first end 16 and a second end 18 configured to connect to a vacuum cleaner 12. A coarse debris retainer 20D may extend between a first debris retainer end 22 connected (e.g., selectively or permanently) to the second end 18 of the vacuum cleaner stick 14 and a second debris retainer end 24 configured to connect to one of the accessories 26 previously described. The coarse debris retainer 20D defines a chamber 28 having a debris chamber inlet opening 30 and a fine debris chamber outlet opening 32. The debris separator 34D is located in chamber 28 between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32. A suction channel 36 is formed between the debris chamber inlet opening 30 and the first end 16 of the suction rod 14.

[0032] like Figure 14The coarse debris retainer 20D, best depicted in the image, with a fourth configuration, includes a sidewall 70D (e.g., a cylindrical sidewall 70D) similar to the first configuration, extending between the first debris retainer end 22 and the second debris retainer end 24. The debris separator 34D with the fourth configuration also includes a cylindrical body 72D defining a fine debris guiding transport section 40 (e.g., inside the cylindrical body 72D). The cylindrical body 72D may be at least partially (e.g., a few, most, or substantially all) formed of a filter 74, such as the previously described mesh filter. More specifically, a fine debris chamber outlet opening 32 may be defined by the first debris retainer end 22 and the cylindrical body 72D. The debris separator 34D may include a rigid frame 76D extending from the fine debris chamber outlet opening 32 to the second debris retainer end 24. The rigid frame 76D may include a plurality of openings 78, and the filter 74 may be located in the openings 78. The opening 78 can occupy a large portion of the surface area of ​​the debris separator 34D (e.g., it can circumferentially surround the cylindrical body 72D). Generally, the surface area and type of the filter 74 between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32 can affect the suction loss between the suction motor 54 and the nozzle 56. Therefore, in the fourth configuration, the large surface area of ​​the filter 74 can have a minimal impact on the suction force. In some embodiments, the cylindrical body 72D is centrally located within the chamber 28 (e.g., along a common axis defining the centers of the cylindrical body 72D and the cylindrical sidewall 70D).

[0033] The second debris retainer end 24 defines a cavity 80 that receives a rigid frame 76D. More specifically, the rigid frame 76D can extend from the first debris retainer end 22 to an end 82 that defines a recess 84 that mates with the cavity 80. The connection between the rigid frame 76D and the cavity 80 can resist forces that could cause buckling between the vacuum cleaner stick 14 and the coarse debris retainer 20D. In some embodiments, one or more conductive members 60 (e.g., wires) can extend through or otherwise onto the rigid frame 76D, and conductive contacts for attachment 26 can be located on the end 82 (e.g., the recess 84). Thus, some attachments may not be energized unless the recess 84 is in the cavity 80. A fine debris chamber output opening 32 can be positioned close to the first debris retainer end 22, and the debris chamber output opening 30 can be defined at least partially by a sidewall 70D between the first debris retainer end 22 and the second debris retainer end 24. The debris chamber inlet opening 30 may include a rubber door 67 that prevents backflow and flexes away from the debris chamber inlet opening 30 when pressurized. In some embodiments, the inlet opening 30 is defined by a region of the sidewall 70D near the second debris retainer end 24. A suction tube 109 extends from the debris chamber inlet opening 30 to an accessory connector 85 outside the chamber 28, which may extend from the second debris retainer end 24. The suction tube 109 may be located within a support bracket 111 that extends at least partially along the sidewall 70D (e.g., along most of the sidewall 70D). The support bracket 111 is formed of a rigid material and is integral with or otherwise attached to the sidewall 70D. The support bracket 111 is resistant to forces that could cause buckling.

[0034] Now for reference Figure 14 and Figure 15 The second debris holder end 24 may be movable relative to the sidewall 70D of the coarse debris holder 20D between a closed position and an open position. In the closed position, the chamber 28 is closed between the debris chamber inlet opening 30 and the fine debris chamber outlet opening 32. In the open position, the chamber 28 is opened to remove the debris 58 contained within the chamber 28. For example, the second debris holder end 24 may pivot relative to the sidewall 70D via a pivot linkage 86.

[0035] The cylindrical body 72D of the debris separator 34A may include a locked position and an unlocked position. In the unlocked position, the cylindrical body 72D can be at least partially removed from the chamber 28 to remove coarser debris 58B. More specifically, a first debris retainer end 22 may define a fine debris chamber outlet opening 32, and the debris separator 34A may be slidable within the fine debris chamber outlet opening 32. The rigid frame 76D may include a collar 91 surrounding the outer surface of the sidewall 70D. The first debris retainer end 22 may define a guide sidewall 94 extending around the fine debris chamber outlet opening 32. The guide sidewall 94 may extend from the sidewall 70D toward the suction stick 14. In some embodiments, the guide sidewall 94 may be cylindrical to receive the cylindrical body 72D. In some embodiments, the guide sidewall 94 or another area of ​​the coarse debris retainer 20D adjacent to the fine debris chamber outlet opening 32 includes an agitator, such as a plurality of bristles 95 ( Figure 14 Multiple bristles 95 surround the fine debris chamber output opening 32 to remove debris 58 from it when the debris separator 34A is at least partially or completely removed. Figure 15 As best depicted, the debris separator 34A can be coupled to the vacuum cleaner stick 14 and can be released relative to the first debris retainer end 22 to obtain an unlocked position. More specifically, the sidewall 70D may include at least one button 97 (e.g., a linearly movable, pivotally movable, or slidable member biased outward toward the neck collar 91), and the rigid frame 76D (e.g., the neck collar 91) may include a button opening 99 that engages with the button 97 in a locked position, in which the user moves the button 97 to align with the button opening 99. In the depicted implementation, a second end 18 of the vacuum cleaner stick 14 is connected to the debris separator 34A. Therefore, in the unlocked position, the vacuum cleaner stick 14 and the debris separator 34A can be pulled out relative to the sidewall 70D. The sidewall 70D may include a stepped surface 101 that interfaces with the bottom edge of the neck collar 91.

[0036] Now for specific reference Figure 16 and Figure 17The cavity 80 is depicted as a through-hole extending through the second debris retainer end 24. Engagement between the cavity 80 and the end 82 (e.g., recess 84) prevents the second debris retainer end 24 from pivoting relative to the sidewall 70D via a pivot linkage 86. More specifically, the second debris retainer end 24 may include a washer 118 defining the cavity 80 and a support ring 120 clamping the washer 118 between the second debris retainer end 24 and a support ring 120. In some implementations, the washer 118 is formed of a flexible or elastic material, and the support ring 120 is formed of a rigid material. The washer 118 may be located in a recess 122 defined by the second debris retainer end 24. Alternatively, the recess 84 may include a wedge-shaped top surface 124 and a circular groove 126 located below the wedge-shaped top surface 124. The recess 84 may be formed of a flexible or elastic material. In operation, the wedge-shaped top surface 124 has a larger outer circular perimeter than the washer 118 (e.g., cavity 80), such that when the wedge-shaped top surface 124 is pressed into the cavity 80, the washer 118 elastically flexes to accommodate the wedge-shaped top surface 124. Once the wedge-shaped top surface 124 has passed through the washer 118, the washer 118 contracts to its original shape and is squeezed into the circular groove 126 in the recess 84 in an airtight or substantially airtight fit.

[0037] Now for reference Figures 1 to 17 One or more conductive members 60 (e.g., wires) extending through the different vacuum stick assemblies 10A to 10D may be communicated with the suction motor 54, for example, via control circuitry. In some embodiments, the control circuitry may permit or prevent certain functionality of the vacuum stick assemblies 10A to 10D based on the state of the suction motor 54. For example, in some embodiments, if the suction motor 54 is energized, the control circuitry may prevent the removal of the vacuum stick assemblies 10A to 10D from the vacuum cleaner assembly 12 or accessory 26 via, for example, one or more electromechanical or electromagnetic locks. Similarly, in some embodiments, if the suction motor 54 is energized, the control circuitry may prevent the removal and / or otherwise opening of the first debris retainer end 22 and / or the second debris retainer end 24.
