Referring to FIGS. 1-9, reference numeral 10 generally designates a vacuum cleaner assembly that generally extends along an axis A. The vacuum cleaner assembly 10 generally includes a handle 12, a body 14, and a dust collection portion 16 extending from the body 14 opposite the handle 12. The body 14 may be generally cylindrical extending about the axis A between a top side and a bottom side. The body 14 includes a battery portion 18 extending from a bottom surface therefrom. The handle 12 extends from the top surface of the body 14 at a downward angle (e.g., a downward angle transverse to the axis A) towards a plane that the bottom side of the body 14 resides. In some embodiments, the handle 12 is coextensive with the body 14. In some embodiments, the handle 12 merges into the body 14 at a rounded (e.g., concave) fillet 15. The handle 12 includes a substantially smaller cross-sectional perimeter than a cross-sectional perimeter of the body 14.

With reference now to FIGS. 1-4, the body 14 defines at least one vent 20 that extends into an internal cavity of the body 14. In some embodiments, the at least one vent 20 includes a plurality of vents 20 that are slot shaped and extend generally horizontally and parallel to the axis A. In other embodiments, the plurality of vents 20 are slot shaped and extend generally about the axis (e.g., vertically between the top surface of the body 14 and the bottom surface). The plurality of vents 20 may be in groupings of equal numbers of vents 20 (e.g., two or more) discretely placed at different locations of the body 14 (FIG. 2). In some embodiments, the at least one vent 20 is located closer to the bottom surface of the body 14 than the top surface. In other embodiments, the at least one vent 20 is substantially equal between the top and bottom surface of the body 14 and/or includes groupings extending upwardly or downwardly from an area of the body 14 that is central between the upper and lower surface of the body 14. The dust collection portion 16 may include a base 22 that extends from the body 14 and narrows to a nozzle 24. In some embodiments, the base 22 includes a body connection end 26 opposite the nozzle 24 and the body 14 includes a base connection end 28 opposite the handle 12. The body connection end 26 and the base 14 may be cross-sectionally equal in size and shape (e.g., cylindrically shaped with an equal radius) such that the base 22 (i.e., excluding the nozzle 24) includes a top surface coextensive with the top surface of the body 14 and a bottom surface coextensive with the top bottom surface of the body 14. The base 22 may extend a distance along the axis A and be substantially cross-sectionally equal to the body connection end 26. A nozzle fillet 30 merges the base 22 into the nozzle 24. The nozzle fillet 30 may include a semi-spherical portion 32 extending (e.g., in a convex shape) from the base 22 that merges into a rounded portion 33 (e.g., in a concave shape) extending to the nozzle 24.

The body 14 may include at least one annular band 34. In some embodiments, the annular band 34 is located adjacent to the base connection end 28. The at least one annular band 34 may include an annular shape (e.g., with one or more pieces forming the annular shape). In some embodiments, the annular band 34 defines an outer annular surface substantially cross-sectionally equal to the body 14. As such, the annular band 34 may be located in an annular groove 36 (FIG. 8) defined in the body 14. It should be appreciated that the annular band 34 could also be other shapes, such as a circumferential array of discretely placed members without departing from the scope of the subject disclosure. When assembled, the annular band 34 visually defines a border between the body 14 and the dust collection portion 16.

With reference now to FIGS. 2-6, the battery portion 18 connects to the body 14 at a battery connection port 38. The battery portion 18 may include at least one first battery connection member 40 (e.g., a pair of diametrically opposed battery supporting clips or protrusions). The battery connection port 38 may include at least one second battery connection member 42 (e.g., a pair of diametrically opposed battery supporting clips or protrusions) that attaches to the at least one first battery connection member 40. The battery portion 18 may therefore be configured to be selectively attached and removed from the body 14 to facilitate charging and/or replacement. The selective removal and attachment may be configured via snap-fit engagement between the at least one first battery connection member 40 and the at least one second battery connection member 42 (e.g., via snapping a pair of diametrically opposed and inwardly biased battery supporting clips over protrusions). In some embodiments, the first battery connection member 40 may include a hook with a release button that articulates the hooks into a non-engagement position in order to release the battery portion 18. The battery connection port 38 may be inset into a depression 44 of the body 14 (FIG. 4). As such, when the battery portion 18 is connected to the battery connection port 38 at least part of a weight of the battery portion 18 is located closer to the axis A than the bottom surface of the body 14.

The battery portion 18 and battery connection port 38 include terminals 46 (FIG. 8) for providing power to the electrical components of the vacuum cleaner assembly 10. The battery portion 18 may include one or more battery modules (not shown) configured, in some embodiments, for 20V operation or 12V operation. The one or more battery modules may be non-removable from the battery portion 18. The battery modules may include Lithium Ion, Nickel-Metal Hydride, Nickel-Cadmium, and/or other materials that permit recharging. It should be appreciated that alternative or additional power sources may be used, for example, the vacuum cleaner assembly 10 may receive AC from a cord and a wall outlet (not shown). The battery portion 18 is removably coupled with the connection port 38 of the body 14 such that a battery portion 18 of, potentially, a number of available compatible battery portions 18 can be selected and attached with the vacuum cleaner assembly 10 for powering the operation thereof by way of the electrical connection facilitated by connection of terminals 47 (FIG. 8) of the battery modules with the terminals 46 of the vacuum cleaner assembly 10 that are exposed within the battery connection port 38. In this manner, the battery portion 18 can be removed from the vacuum cleaner assembly 10 for use with one or more other compatible appliances (such as a hand mixer, a hand blender, a countertop blender) or to be replaced with a charged battery portion 18, such as when the in-use battery portion 18 has become depleted. In this manner, a depleted battery portion 18 can be charged using a compatible charger having mechanical components similar to the battery connection port 38 and terminals described in connection with the present vacuum cleaner assembly 10. An example of such a charger is described in the co-pending, commonly-assigned U.S. Provisional Patent Application Ser. No. 63/315,355, the entire contents of which are incorporated by reference herein. Another example of such a charger is described in the co-pending, commonly-assigned U.S. patent application Ser. No. 18/115,069 filed Feb. 28, 2023, and claiming benefit of U.S. Patent Provisional Application Serial Nos. 63/407,933 and 63/315,355, the entire contents of each are incorporated by reference herein.

With reference now to FIG. 5, at least one illumination element 50 may be located on the battery portion 18, the handle 12, and/or the body 14.

In some embodiments, the at least one illumination element 50 includes a plurality of between 2 and 5, between 2 and 4, between 3 and 5, 2, 3, or 4 illumination elements 50. The notification may include the number of the illumination elements 50 that are illuminated, a color (e.g., out of several) of the illumination, a pattern of flashing, and/or an intensity of the illumination.

With reference now to FIGS. 3, 4, 6 and 7, the nozzle 24 extends substantially centrally about the axis A. The nozzle 24 includes a nozzle face 52 with a top edge 54 and a bottom edge 56 extending between a pair of side edges 58 (FIGS. 6 and 7). From the front (FIG. 6) the nozzle face 52 defines width “W” and a height “H.” In some embodiments, the width W is greater than the height H, for example, by an order of magnitude of about 2. The top edge 54 and the bottom edge 56 may both be substantially linear and the side edges 58 may each be rounded (e.g., equally and oppositely). As best illustrated in FIGS. 4 and 7, the nozzle face 52 may be angled. More particularly, the top edge 54 may extend further away from the body 14 than the bottom edge 56 whereat the side edges 58 extend at an angle with respect to the axis A. The angle defined by the handle 12 has a magnitude between the axis A and the angle defined by the side edges 58 of the nozzle 24. The nozzle 24 may include an attachment connection member 60 (e.g., a protrusion in FIG. 7) for connecting various vacuum attachments such as brushes, flexible tubes, other nozzles of different shapes, and/or the like (FIGS. 11-14).

With reference now to FIGS. 1, 3, 5, 8 and 9, the vacuum cleaner assembly 10 includes a user interface 62. The user interface 62 may be located substantially on the handle 12 and may extend at least partially on the body 14. The user interface 62 includes at least one button region 64, 66 that may include include a power button region 64 and a boost button region 66. The power button region 64 and the boost button region 66 may be spaced from one another or otherwise configured as the same button. It should be appreciated that the term “button” may include other forms of switches, toggles, mechanical, and/or electrical (e.g., touch activated) sensors. The user interface 62 may be located in a small depression or reside substantially flush with the handle 12 and body 14. In some embodiments, the power button region 64 and the boost button region 66 may be a single button with functionality dictated by which region of the singular button is pressed (or different distinct interactions with a single region). In some embodiments, the vacuum cleaner assembly 10 turns on and off in a lower-speed mode when the power button region 64 is pressed and depressing the boost region 66 activates a higher-speed mode while held.

With continued reference to FIGS. 1, 3, 5, 8 and 9, the control unit 74 may be configured to apply different vacuum strengths based on at least one functional sequence of activating the button region 64, 66. The at least one functional sequence may include a first functional sequence that includes pressing and releasing the button region 64, 66 causing the control unit 74 to facilitate a normal speed of the impeller 77 causing a normal suction strength. During the normal speed of the impeller 77, a user may press and hold the button region 64, 66 causing the control unit 74 to facilitate a high speed of the impeller 77 causing a high suction strength greater than the normal suction strength. During the high speed of the impeller 77, a user may release the button region 64, 66 causing the control unit 74 to facilitate the normal speed of the impeller 77. In some embodiments, the at least one functional sequence may include a second functional sequence in addition to the first functional sequence that includes, while the impeller 77 is at a zero speed, pressing and holding the button region 64, 66 causing the control unit 74 to facilitate the high speed of the impeller 77 causing the high suction strength. During the high speed of the impeller 77, a user may then release the button region 64, 66 causing the control unit 74 to facilitate a normal speed of the impeller 77 with a normal suction strength that is less than the high suction strength.

With reference now to FIG. 8, the vacuum cleaner assembly 10 is shown in a disassembled condition to illustrate internal components. In some embodiments, the handle 12 and body 14 are formed of a two-piece housing construction including a top housing portion 68 and a bottom housing portion 70 that are connected by a series of connection clips 72. The base connection end 28 may include a cross-sectionally different perimeter (e.g., smaller or larger) than the body connection end 26 such that the base connection end 28 can be securely fit (e.g., press-fit, snap-fit, and/or the like) into (e.g., when the perimeter is smaller) or outside (e.g., when the perimeter is larger) of the body connection end 26. A control unit 74 is located in the body 14 and may include a PCB that locates a processor and a memory. The processor may include any suitable processor or number of processors. The memory may comprise a single disk or a plurality of disks (e.g., hard drives), and includes a storage management module that manages one or more partitions within the memory. In some embodiments, the memory may include flash memory, semiconductor (solid state) memory or the like. The memory may include Random Access Memory (RAM), a Read-Only Memory (ROM), or a combination thereof. The memory may include instructions that, when executed by the processor, cause the processor to, at least, perform the functions associated with the components of the vacuum cleaner assembly 10 (e.g., the user interface 62, the illumination elements 50 and notifications associated therewith, and/or the like). It should be appreciated that the control unit 74 may include other configurations without departing from the subject disclosure, such as a logic control circuit with or without the processor and/or memory.

With continued reference to FIG. 8, a motor 76 and an impeller 77 (FIG. 9) driven by the motor 76 may be located in the body 14 and balanced substantially along the axis A. The at least one vent 20 functions as an outlet from air drawn from the impeller 77. The impeller 77 may be located in an impeller housing 78 that defines a suction aperture 80 extending about the axis A. In some embodiments, the motor 76 and impeller 77 are part of a singular unit. The motor 76 and impeller 77 are located within the body 14 via a motor housing 81 that includes a series of fins 82 that extend radially outwardly and contact and inner wall of the body 14. The body 14 includes a connection ring 84 (FIG. 10) that is located between the impeller 77 and the dust collection portion 16. A gasket 85 (e.g., of annular shape) may be located between the impeller housing 78 and the connection ring 84. The connection ring 84 includes a first filter or grill shaped array 86 for preventing debris from entering the suction aperture 80. A second filter 88 is located at least partially within the dust collection portion 16 (FIG. 9). The second filter 88 includes a filter frame 90 defining a cup shape and at least one mesh cover 92 (e.g., a pair of mesh covers). The second filter 88 further includes an annular frame 94 and a filter cup 96 (e.g., a HEPA filter) extending from the annular frame 94 to a top plate 98. The filter cup 96 may be located within the at least one mesh cover 92 and the filter frame 90.

Referring now to FIGS. 8 and 9, the nozzle 24 includes an internal portion 100 that extends into the base 22. The nozzle 24 includes an internal surface 102 defining a passage that expands radially outwardly at the internal portion 100 to a dust collection cavity 103 defined by an interior surface of the dust collection portion 16. A door 104 is located on an end of the internal portion 100 opposite the nozzle face 52 and provides a semi-seal for the internal surface 102 such that debris cannot exit the dust collection cavity 103. When the impeller 77 is actuated, the door 104 pivots away from the internal portion 100 as a result of negative pressure to permit debris to enter into the dust collection portion 16 where it is retained by the second filter 88. The door 104 includes a door connection 106 that is retained within a pocket 108 defined by the internal surface 102. In some embodiments, the door 104 is formed of elastic material such that it is deformed upon pivoting. It should be appreciated that the door 104 and door connection 106 may alternatively have a mechanical hinge type configuration with relative moving parts. The handle 12 includes an internal and hollow post 109 (e.g., extending from the top housing portion 68 and the bottom housing portion 70) that a fastener can be used to further secure the top housing portion 68 and the bottom housing portion 70. The battery portion 18 may include a battery control unit (not shown) which may be used alternatively or in conjunction to perform the functionality of the control unit 74 and may provide further functionalities (e.g., surge protection, charging control, and the like). The batter control unit may share all the same features and functionalities as the control unit 74.

With reference now to FIG. 10, an interior surface of the body connection end 26 defines at least one first track 110 (e.g., one, two, three, or more) extending along the axis A and a first lock passage 112 extends perpendicular from the track 110. An exterior surface of the nozzle connection portion 28 defines at least one second track 114 (e.g., one, two, three, or more) extending along the axis A and a second lock passage 116 extends perpendicular to the second track 114. The connection ring 84 includes internal protrusions 118 and external protrusions 120. In operation, the internal protrusions 118 enter the second track 114 and become interlocked within the second lock passage 116 upon relative rotation. The connection ring 84 may be fastened to the body 14 with additional fasteners for a substantially permanent connection without intermediary tools. Likewise, the external protrusions 120 enter the first track 110 and become interlocked within the first lock passage 112 upon relative rotation. In this manner, the body connection end 26 and the nozzle connection portion 28 can be removably coupled thereto. In other words, the connection ring 84 may form or otherwise define the base connection end 28. As such, as the dust collection portion 16 becomes filled with debris, it can be easily removed from the base connection end 28 and emptied. It should be appreciated that, in some embodiments, the base connection end 28 may include the connection ring 84 and in other embodiments the body connection end 26 may include the connection ring 84.

With reference now to FIG. 11, the vacuum cleaner assembly 10 may include various vacuum attachments including a scraper attachment 122. The scraper attachment 122 may extend between a nozzle connection mouth 124 and a scraper bucket 126. The scraper attachment 122 may include an aperture 128 for insertion of the attachment connection member 60 (FIG. 7). The aperture 128 may be located adjacent to the nozzle connection mouth 124. The scraper bucket 126 includes a top edge 130 and a bottom edge 132 extending between a pair of side edges 134. The top edge 130 and the bottom edge 132 may both be substantially linear and the side edges 134 may each be angled between the top edge 130 and the bottom edge 132. The bottom edge 132 defines a lip 136 that extends to an apex 138 that is narrow or blade-like. In this manner, the lip 136 (e.g., apex 138) can effectively scrape a cleaning surface during operation disrupting and collecting debris for an efficient cleaning operation.

With reference now to FIG. 12, the scraper attachment 122 may include a connection feature 139 (e.g., aperture, clip, and/or the like) for connection to another vacuum attachment, such as a crevice attachment 140. The crevice attachment 140 may likewise include a connection feature 141 (e.g., a corresponding aperture, clip, and/or the like) for removably coupling with the connection feature 139 of the scraper attachment 122. In this manner, two vacuum attachments can be simultaneously coupled to the nozzle 24 for easy switching. For example, one attachment may provide suction and scrapping (e.g., the scraper attachment 122) while the other attachment provides brushes. Likewise, one attachment may provide suction and crevice cleaning (e.g., the crevice attachment 140) while the other attachment provides scrapping and collecting (e.g., scraper attachment 122) or vise-versa. The crevice attachment 140 may include a nozzle connection mouth 142 and an aperture 144 for insertion of the attachment connection member 60 (FIG. 7). Both the scraper attachment 122 and the crevice attachment 140 may include recessed grip portions 146. In some embodiments, the grip portions 146 are mechanically interlinked with the connection features 139, 141 to articulate an engagement member and facilitate removal.

With reference now to FIGS. 13 and 14, the vacuum assembly 10 may include a storage base 148. The storage base 148 may include an outer perimeter 150 and a floor 152. A ridge 154 may extend around the outer perimeter 150. A plurality of posts may extend from the floor 152 in an upward direction. The plurality of posts may include a nozzle connection post 156 and an at least one attachment connection post 158. In the illustrated embodiment, the storage base 148 includes a pair of attachment connection posts 158 and one nozzle connection post 156 located centrally therebetween. The attachment connection posts 158 may have the same general profile as the nozzle face 52 from FIG. 6 (e.g., substantially the same width W and a height H with or without being angled). The attachment connection posts 158 may also define protrusions 160 similar in size and dimension to the connection member 60 illustrated in FIG. 7. In this manner, the vacuum attachments (e.g., scraper attachment 122 and the scraper attachment 140) may connect to the attachment connection posts 158 in a same or similar fashion as the vacuum attachments connect to the nozzle 24. The nozzle connection post 156 may be similar in size and dimension to the nozzle connection mouths 124, 142. The nozzle connection post 156 may define an aperture 162 (e.g., a depression or pocket) similar in size and dimension to the apertures 128, 144. In this manner, the nozzle 24 may connect to the nozzle connection post 156 in the same manner that the nozzle 24 connects to the nozzle connection mouths 124, 142 of the various vacuum attachments. In some embodiments, the nozzle connection post 156 and the attachment connection posts 158 are oblong in shape that are longer in a first direction than a second direction. In some embodiments, the nozzle connection post 156 is located at an angle (e.g., 90°) from the attachment connection posts 158 such that the long directions between posts 156 and 158 are different (e.g., 90°). The nozzle connection post 156 is configured to at least support the dust collection portion 16. In this manner, the dust collection portion 16 may be substantially balanced about the axis A, such that a center of mass of the dust collection portion 16 extends centrally or substantially centrally along the axis A. In some embodiments, the nozzle connection post 156 is further configured to also support the body 14 when attached to the dust collection portion 16. In this manner, the body 14 may be substantially balanced about the axis A, such that a center of mass of the body 14 extends centrally or substantially centrally along the axis A. As such, the body 14 and dust collection portion may extend and be balanced vertically on the storage base 148.
