DETAILED DESCRIPTION

FIG. 1 illustrates an attachment 100 for a vacuum device 10 (e.g., a vacuum cleaner, portable vacuum cleaner, etc.) according to an embodiment of the present disclosure. The attachment 100 includes a head housing 104 and a suction tube 108. The head housing 104 defines an interior volume therein, the interior volume forming a brush roll cavity 112, a motor cavity 116, and a battery cavity 120. The head housing 104 extends rearwardly in a widthwise direction from a front side 124 to a rear side 128, opposite the front side. In a lengthwise direction, perpendicular to the widthwise direction, the head housing 104 extends between a first sidewall 132 (as shown, a left sidewall) and a second sidewall 136 (as shown, a right sidewall), opposite the first sidewall 132. Vertically, the head housing 104 extends between a bottom side 140 and a top side 144, opposite the bottom side 140. The bottom side 140 is a ground engaging surface such that in operation, the bottom side 140 moves along a ground (or other generally horizontal) surface to be cleaned. The bottom side 140 may include a sole plate that provides a seal on the surface to be cleaned while the tool is held at different angles.

The brush roll cavity 112 is located adjacent the front side 124 of the head housing 104 and is nearer to the front side 124 than the motor cavity 116 and the battery cavity 120. In the embodiment shown, the brush roll cavity 112 extends nearly completely (e.g., at least 90%) the length of the head housing 104 between the first and second sidewalls 132, 136. Further, the brush roll cavity 112 extends vertically between the bottom side 140 and the top side 144. A brush roll 148 is positioned within the brush roll cavity 112 and is configured to rotate within the brush roll cavity 112. In some embodiments, a portion of the housing 104 defining the brush roll cavity is transparent and/or translucent such that the brush roll 148 is visible within the brush roll cavity 112 through the head housing 104.

The brush roll 148 includes a generally cylindrical body 152 having bristles 156, fins 158 and/or other debris collection devices extending radially outward from the body 152. In some embodiments, one or more fin 158 extend around the body 152 in a helical pattern between the two ends of the body 152. Other embodiments may have linearly extending fins or no fins. In some embodiments, other debris collection devices can include an anti-hair wrapping feature. In one embodiment, the fins 158 can provide an anti-hair wrapping feature. The brush roll 148 is mounted within the brush roll cavity 112 and is configured to rotate about a rotational axis a1. The rotational axis a1 extends generally perpendicular to the first and second sidewalls 132, 136 of the head housing 104. The brush roll cavity 112 includes an opening 168 (FIG. 5) in the first sidewall 132 of the head housing 104 through which the brush roll 148 is removable from the brush roll cavity 112 and insertable into the brush roll cavity 112. In some embodiments, a cap 170 is removed from the opening 168 to provide access to the interior of the brush roll cavity 112. The cap 170 is shown in FIG. 2 in both a locked position and an unlocked position (rotated relative to the locked position). Indicia 174 is provided on the head housing 104 adjacent the cap 170 that provides instructions for rotating the cap 170 between a locked position (indicated by a closed lock of the indicia 174) and an unlocked position (indicated by an open lock of the indicia 174). An arrow between the two lock symbols indicates the direction of locking and unlocking. In other embodiments, the cap 170 is integrally formed with the brush roll 148. In some embodiments, the cap 170 is a tool-free brush roll cap that is removable by a user (e.g., graspable and rotatable) without the assistance of a tool. In other embodiments, the brush roll cap 170 is removable with a tool (e.g., a wrench, a screwdriver, etc.) Removing and/or inserting the brush roll 148 through the opening 168 includes translating the brush roll 148 along the axis a1.

The brush roll 148 shown in the figures and described within the specification is only one of a plurality of different types and designs of brush rolls usable with the accessory. Different brush rolls may include bristles of different thicknesses, stiffnesses, and arrangements. Additionally, different material types may be employed, such as, for example, a microfiber type brush roll. Further, designs of other brush rolls may include different debris collection devices beyond fins and bristles.

The brush roll cavity 112 includes a brush roll cavity inlet 160 defined in the bottom side 140 of the head housing 104. The brush roll cavity inlet 160 extends substantially the same length as the brush roll 148 such that when the brush roll 148 is mounted within the brush roll cavity 112, at least some of the bristles 156 of the brush roll 148 protrude through the inlet 160 and into engagement with the ground surface. In some embodiments, the inlet 160 is rectangular. The brush roll cavity inlet 160 is a debris inlet through which debris is introduced into the attachment 100. As the brush roll 148 is rotated within the brush roll cavity 112 about the rotational axis a1, the brush roll loosens and/or grabs debris from the ground surface. When the attachment 100 is coupled to the vacuum device 10, the vacuum device 10 generates a suction airflow that draws debris into the attachment 100 through the inlet 160.

The brush roll cavity 112 additionally includes a brush roll outlet 164 through which the debris in the brush roll cavity 112 is moved out of the brush roll cavity 112. The brush roll outlet 164 is narrower than the brush roll inlet 160 and is centered between the first and second sidewalls 132, 136 of the head housing 104. Additionally, while the inlet 160 is located at the bottom side 140, the outlet 164 is located at or adjacent to the top side 144. The brush roll outlet 164 introduces debris from the brush roll cavity 112 into the inlet 172 of the suction tube 108.

The suction tube 108 is a generally linear tube extending upward and rearward from the top side 144 of the head housing 104. In some embodiments, the suction tube 108 is overmolded onto the head housing 104 at the brush roll outlet 164. The suction tube 108 is hollow, defining an interior passageway that extends from the suction inlet 172 at the outlet 164 of the brush roll cavity 112 to a suction outlet 176 at an opposite end. As shown in FIG. 4, the suction tube 108 extends at a convex angle θ1 relative to a ground surface supporting the bottom side 140 of the head housing 104. In some embodiments, the angle θ1 is approximately 35 degrees (e.g., 30-40 degrees, 20-50 degrees). As shown, the length (i.e., axial length) of the suction tube 108 between the suction inlet 172 and suction outlet 176 extends beyond the rear side 128 of the head housing 104. The suction outlet 176 at the distal end of the suction tube 108 is configured to engage the vacuum device 10 (e.g., a hose of the vacuum device 10) to provide a suction airflow path from the vacuum device 10 to the brush roll cavity 112 of the attachment 100. The suction outlet 176 includes an adapter 180 or engagement feature that engages the vacuum device 10 to secure the attachment 100 to the vacuum device 10. As shown, the adapter 180 includes a sloped surface to have differing diameters along its length such that the adapter 180 is configured to couple hoses, tubes, and extension wands of various diameters (e.g., 1¼″ diameter, 1⅞″ diameter, 2½″ diameter) that are either parts of vacuum device 10 or separate parts from the vacuum device 10. The adapter 180 may be overmolded onto the suction tube 108 or may be otherwise attached (e.g., via an adhesive). In some embodiments, the graduated surface of the adapter 180 attaches to the hoses, tubes, and extension wands only via a friction fit, and/or a compression fit from a compressive force applied to the hoses, tubes, and extension wands by an outer wall of the adapter 180 due to elastic deformation of a material of the adapter 180. In other embodiments, the engagement feature additionally includes a locking connector that requires a user input (e.g., to a lever or a button) to detach the attachment 100 from the hoses, tubes, and extension wands.

The motor cavity 116 is positioned rearward of the brush roll cavity 112 (i.e., nearer to the rear side 128 than the brush roll cavity 112). The motor cavity 116 is offset left-to-right, located nearer to the second sidewall 136 than the first sidewall 132. The motor cavity 116 is positioned entirely between the suction tube 108 and the second sidewall 136. A motor 184 is positioned within the motor cavity 116 of the head housing 104. The motor 184 includes an output shaft 188 that rotates (i.e., when energized) about a rotational axis a2. The motor 184 is generally cylindrical, substantially centered on the rotational axis a2 of the output shaft 188. The output shaft 188 is coupled to a transmission 192 (e.g., a plurality of gears and/or belts), which is coupled to the brush roll 148 such that rotation of the output shaft 188 of the motor 184 about axis a2 generates rotation of the brush roll 148 about axis a1. The rotational axis a2 of the motor 184 is generally parallel to the rotational axis a1 of the brush roll 148.

The battery cavity 120 is a substantially cylindrical cavity defining a central axis a3. The central axis a3 extends generally parallel to the rotational axes a1, a2 of the brush roll 148 and the motor output shaft 188. The battery cavity 120 is positioned rearward of the motor cavity 116 (i.e., nearer to the rear side 128 than the motor cavity 116). The battery cavity 120 extends between an opening 208 in the first sidewall 132 and an electrical connector 216. A removable battery 196 is insertable into the battery cavity 120 and is configured to engage the electrical connector 216 to provide power to the motor 184. In some embodiments, the removable battery 196 is a 4V rechargeable battery. The removable battery 196 includes a generally cylindrical body 200 sized to slide within the battery cavity 120 along the central axis a3. A cap 204 is coupled to the cylindrical body 200 and extends outside of the battery cavity 120 to provide a grip for a user to grasp the battery 196 when installed within the battery cavity 120. As shown in FIG. 5, a portion of the cylindrical body 200 likewise extends outside of the battery cavity 120 within the cap 204. The cap 204 engages the opening 208 through which the battery 196 through which the battery is inserted and removed from the battery cavity 120 to secure the battery 196 to the head housing 104. In some embodiments, the cap 204 may include an engagement portion 212 (e.g., a threaded engagement portion) that engages threads (or other engagement features) of the housing 104 to secure the removable battery 196 to the head housing 104. In other embodiments, the cap 204 may be separate from the removable battery 196 and removable from the opening 208 to provide access to the removable battery 196 located within the battery cavity 120.

A power input 220 is provided on the attachment 100 (e.g., on the top side 144 of the head housing). The power input 220 may be formed as a button, a switch, or another user input. The power input 220 is movable between an engaged position and a disengaged position. In the engaged position, the motor 184 is energized to rotate the brush roll 148 within the brush roll cavity 112. In the disengaged position, the motor 184 is deenergized such that the output shaft 188 does not rotate and the brush roll 148 is not rotated by the motor 184. In some embodiments, a mode selection input may additionally be provided on the attachment 100 to operate the attachment 100, and specifically the motor 184 and brush roll 148 in various modes such as, high speed, low speed, constant speed, variable speed, forward, reverse, etc.

With reference to FIG. 1, an indicator light 224, as shown an LED (light emitting diode) indicator light, is positioned adjacent the power input 220 and indicates various statuses of the attachment 100. More specifically, in the embodiment shown, the LED indicator light 224 is positioned on the top side 144 of the head housing 104 forward of the power input 220. In some embodiments, the indicator light 224 is controlled to be green when the attachment 100 is powered on and the state of charge of the battery 196 is higher than a threshold value (e.g., battery voltage is greater than or equal to 50%, greater than or equal to 25%, etc.). In some embodiments, the indicator light 224 is controlled to be red when the attachment 100 is powered on and the state of charge of the battery 196 is below the threshold value. Further still, in some embodiments, the indicator light 224 is controlled to be flashing red in the event of an anomaly.

A work light 228 is positioned on the front side 124 of the head housing 104 of the accessory 100 and is configured to illuminate the ground surface ahead of the accessory 100 that is to be cleaned. In the embodiment shown, the work light 228 is an LED work light having one or more (e.g., two) LEDs positioned behind a translucent (or transparent) screen. The work light 228 is positioned above the brush roll cavity 112 and is generally centered between the first and second sides 132, 136 of the head housing 104. The work light 228 may be turned on automatically when the accessory 100 is turned on (via the power input 220). Alternatively, the work light 228 may have a separate power switch or may turn on in low-light environments (e.g., in response to a signal from a light sensor).

A printed circuit board assembly (PCBA) 250 is provided within the head housing 104. As shown in FIG. 5, the PCBA 250 is oriented substantially vertically within the head housing 104 (i.e., such that the planar surface of the circuit board assembly 250 extends vertically) and is located between the battery cavity 120 and the brush roll cavity 112. In some embodiments, the PCBA 250 is generally aligned with the axis a2 of the output shaft 188 of the motor 184. The PCBA 250 is secured to the head housing 104 via, for example, fasteners and/or interaction with the head housing 104, such as sliding within a slot defined by one or more surfaces of the head housing 104. The PCBA 250 may further include other circuit boards positioned within the head housing 104, such as a first separate circuit board positioned adjacent to (e.g., underneath) the power input 220 and LED indicator light 224 and a second separate circuit board positioned adjacent (i.e., behind) the lens of the LED work light 228.

The PCBA 250 is a controller for the attachment 100. The PCBA 250 controls operation and monitoring of the battery 196 and the motor 184. The PCBA 250 controls operations of the motor 184 including activating the motor 184 (i.e., turning the motor 184 on such that the output shaft 188 rotates), deactivating the motor 184 (i.e., turning the motor 184 off such that the output shaft 188 does not rotate), and, if the motor 184 is a variable speed motor, controlling the speed of the motor 184 (i.e., the speed of the output shaft 188 of the motor 184), thereby controlling the rotational speed of the brush roll 148. Additionally, the PCBA 250 monitors operation of the accessory 100 to identify anomalies (e.g., as a stall from an item caught in the brush roll 148 resulting in a current spike) and modify operation of the battery 196 and/or motor 184 in response. The PCBA 250 further controls the output of the indicator light 224 to change whether the indicator light 224 is on or off, the color (e.g., red, green) of the indicator light 224, and/or the pattern (e.g., solid light, blinking light at a first speed or pattern, blinking light at a second speed or pattern, etc.) of the indicator light 224. Further still, in some embodiments, the PCBA 250 sets and/or changes the threshold value of the battery 196 that dictates the output of the indicator light 224 based on the current draw level of the motor 184 during operation. The PCBA 250 also controls operation of the LED work light 228 (e.g., turning the work light 228 on and off).

As shown in FIG. 6, the head housing 104 has a length L3 extending between the first and second sidewalls 132, 136. A width w3 of the head housing 104 is measured between the front and rear sides 124, 128 and is generally perpendicular to the length L3. The width w3 is measured in a direction of travel of the attachment 100 during normal use. The length L3 is substantially parallel to the axes a1, a2, a3. As shown, the width w3 of the head housing 104 is at least 80% (e.g., between 80%-100%) of the length L3 of the head housing 104, thereby providing a compact form factor of the head housing 104.

FIG. 3 illustrates a cross-section through the center of the suction tube 108, normal to the axes a1, a2, a3 (shown in FIGS. 5-6). The suction tube 108 extends linearly from the suction inlet 172 at the brush roll cavity 112 to the suction outlet 176 at the adapter 180. The suction tube 108 extends rearwardly from the inlet 172 to the outlet 176, but simultaneously extends upward such that, when viewed in a direction along the axes a1, a2, a3 as shown in FIG. 3, the suction tube 108 does not overlap the battery cavity 120. As such, the battery cavity 120 is not limited to fitting on one side of the suction tube 108, but extends behind and below the suction tube 108 to decrease the overall width of the head housing 104. FIGS. 5-6 illustrate that a portion of the battery cavity 120 (between the opening 208 and the electrical connector 216) extends in a lengthwise direction (along L3) beyond a centerline of the suction tube 108, which is achievable as the battery cavity 120 is located rearward of the suction tube 108.

In contrast, as shown in FIG. 4, the suction tube 108 overlaps a portion of the motor 184 when viewed in a direction along the rotational axis a2 of the motor 184. As such, the motor 184 is disposed entirely on one side of the suction tube 108 so as to not contact or extend into the suction tube 108. As shown in FIG. 5, the motor 184 has a length L1 that is less than the length L2 of the battery cavity 120 such that the motor can fit to one side of the suction tube 108 without significantly increasing the overall length L3 (FIG. 6) of the head housing 104.

The length L2 of the battery cavity 120 and the length L1 of the motor 184 do not overlap one another such that a gap is present between the lengthwise extents of the motor 184 and the battery cavity 120. The collective lengths L1 and L2 of the motor 184 and battery cavity 120 correspond to a majority (e.g., over 50%, over 75%) of the overall length L3 of the head housing 104. As the lengths L1 and L2 do not overlap with one another, the width w1 of the motor 184 and the width w2 of the battery cavity 120 are capable of overlapping, as shown in FIG. 5, without the motor cavity 116 and battery cavity 120 physically interfering with one another.

With continued reference to FIG. 5, the substantially parallel axes a1, a2, a3 are spaced apart from one another to fit within the head housing 104. The rotational axis a2 of the output shaft 188 of the motor 184 is spaced apart rearwardly from the rotational axis a1 of the brush roll 148 by a first distance d1. The central axis a3 of the battery cavity 120 is spaced apart rearwardly from the rotational axis a2 of the output shaft 188 of the motor 184 by a second distance d2. In this way, the central axis a3 of the battery cavity 120 is spaced apart rearwardly from the rotational axis a1 of the brush roll 148 by a distance greater than either distance d1, d2, equal to the combination of the distance d1 and distance d2. The length L3 of the head housing 104 is decreased compared to an arrangement in which one or more of the axes a1, a2, a3 are aligned (i.e., colinear). Additionally, the length L3 of the head housing 104 is decreased by positioning the battery cavity 120 rearward to not physically interfere with the suction tube 108.

In some embodiments, the distance d1 between the rotational axes a1 and a2 of the brush roll 148 and the motor output shaft 188 is greater than the distance d2 between the rotational axis a2 of the output shaft 188 of the motor 184 and the central axis a3 of the battery cavity 120 as the brush roll cavity 112 has a larger diameter than the width w1 of the motor cavity. In some embodiments, the distance d2 is at least 40% (e.g., 40%-70%, 40%-100%) of the distance d1.

In some embodiments, the attachment 100 is not itself a vacuum device as it omits a system for generating a suction airflow but is instead an attachment 100 for collecting debris when coupled to a vacuum device 10. In some embodiments, the attachment 100 is separable from the vacuum device 10.

Although the present subject matter has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the scope of one or more independent aspects of the subject matter as described.
