Description
[Technical field]
[0001] Related Applications This specification relates generally to surface cleaners, and more particularly to handheld surface cleaning devices and cleaning systems implementing the same.
[0002]
[0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 561,851, filed September 22, 2017, U.S. Provisional Patent Application No. 62 / 585,320, filed November 13, 2017, U.S. Provisional Patent Application No. 62 / 616,908, filed January 12, 2018, and U.S. Provisional Patent Application No. 62 / 619,309, filed January 19, 2018, each of which is incorporated by reference in its entirety into this specification. [Background technology]
[0003]
[0003] Vacuum cleaners and other surface devices may have multiple components that each receive power from one or more power sources (e.g., one or more batteries or electric mains). For example, a vacuum cleaner may include a suction motor that generates a vacuum in a cleaning head. The generated vacuum collects dust from the surface being cleaned and deposits the dust in a dust collector. The vacuum cleaner may also include a motor that rotates a brush roll in the cleaning head. The rotation of the brush roll agitates dust attached to the surface being cleaned so that the generated vacuum can remove the dust from the surface. In addition to the electrical components for cleaning, the vacuum cleaner may include one or more light sources for illuminating the area being cleaned.
[0004]
[0004] Vacuum cleaners generally occupy a relatively large amount of space in a closet or other storage location. For example, an upright vacuum cleaner tends to be kept in an upright position during use when stored away for future use. To this end, storage of the vacuum cleaner requires space to accommodate the overall height and width of the vacuum cleaner. This relegates vacuum cleaners to storage locations in out-of-sight locations, such as closets, garages, or other hidden areas. Such locations may be some distance away from rooms or other locations that require regular cleaning, and therefore may be cleaned less because transporting the vacuum cleaner to and from the storage location is impractical or otherwise inconvenient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0007]
[0060] In general, the present disclosure is directed to handheld surface cleaning devices that include a relatively compact form factor that allows a user to store it in a nearby location (e.g., in a drawer, in an associated charging dock, on a tabletop) for easy access to perform relatively small cleaning tasks that would otherwise require removing a full-sized vacuum cleaner from storage. Consistent with aspects of the present disclosure, a handheld surface cleaning device includes a body (or body portion) with a motor, a power source, and a dust cup disposed therein. The body portion functions as a hand grip, for example, allowing the handheld surface cleaning device to be operated with one hand. Thus, the body portion may be referred to as a hand grip, a handle portion, or simply a handle.
[0008]
[0061] In one embodiment, a handheld surface cleaner consistent with the present disclosure includes a body defining a handle portion and a dirty air passageway. The body may define a cavity for holding a motor for generating suction to draw dirt and debris into the dirty air passageway, a power source for powering the motor, and a dust cup for receiving and storing dirt. Each of the components within the body may be coaxially disposed. Each of the power source, motor, and dust cup may include a shape generally corresponding to the body of the handheld surface cleaner (e.g., substantially cylindrical, rectangular, etc.). Thus, the body may include a relatively continuous width about its length, which allows a user to comfortably grip the hand within the body during a cleaning operation. The handheld surface cleaning device also includes a cleaning head (or nozzle) that includes a longitudinal axis parallel to the body, which in a general sense enables the handheld surface cleaning device to be operated similarly to a wand of a conventional full-sized vacuum cleaner for cleaning without an additional bulky trailing hose and to target a variety of surfaces.
[0009]
[0062] As generally referred to herein, dust and dirt means dirt, dust, water, or any other particle that can be drawn by suction into a handheld surface cleaning device.
[0010]
[0063] 1-4 illustrate a handheld surface cleaning device 100 according to an embodiment of the present disclosure. As shown, the handheld surface cleaning device 100 includes a body 102 extending along a longitudinal axis 116 from a first end 140 to a second end 142. The body 102 of the handheld surface cleaning device 100 includes a handle portion 104 adjacent the first end 140, followed by a motor portion (or section) 106, a filter portion 108, a dust cup 110, and a nozzle 114 disposed adjacent the second end 142. The body 102 can include a substantially flat and continuous surface 180 extending from the first end 140 to the second end 142, forming a "wand"-like device. In one embodiment, the handle portion 104, the motor portion 106, the filter portion 108, and the nozzle 114 can be formed as a single monolithic piece. In other cases, portions such as the nozzle 114 and / or the filter portion 108 may be removable.
[0011]
[0064] As shown, the handle portion 104 of the handheld surface cleaning device 100 is contoured to fit comfortably within a user's hand during operation. The tapered region 146 may advantageously allow a user's hand and fingers to more comfortably grip and manipulate the handheld surface cleaning device 100. The body 102 of the handheld surface cleaning device 100 further includes an on / off button 118 and a dust cup release button 112. The on / off button 118 and dust cup release 112 may be actuated, for example, by the thumb of the user's hand when the handle portion 104 is held. Dust Cup Release 112 may be displaced and slidably engaged, for example, by a user's thumb to unlock the dust cup 110, described in more detail below. The dust cup release 112 may be spring biased to return to a rearward position in the absence of a user-supplied force.
[0012]
[0065] The motor section 106 of the body 102 may include circuitry (not shown) for selectively supplying power to a motor 126 (see FIG. 4) disposed therein. The motor 126 may be a DC motor or other suitable motor for generating suction. In some embodiments, the handheld surface cleaning device 100 may include a vortex arrangement, and the illustrated embodiments are not intended to limit the disclosure. The motor 126 generates suction that draws air into the dirty air inlet 120. The amount of power supplied to the motor 126 may be varied to proportionally adjust the amount of suction force. Alternatively, the on / off button 118 may simply supply a constant amount of power to the motor 126.
[0013]
[0066] Subsequently, the dust cup 110 may be configured to receive dirt and dust received via the dirty air inlet 120. As shown, the dust cup 110 is rotatably coupled to the body 102, and more specifically to a portion of the dirty air inlet 120 via a hinge 149, which is formed by a pin that passes substantially through the body 102, substantially transverse to the longitudinal axis 116. The nozzle 114 may provide the hinge 149. In some cases, the nozzle 114 may be removable. Thus, the dust cup 110 may rotate along a first axis of rotation, for example, when released via the dust cup release 112. For example, as shown in FIG. 3, the dust cup 110 may rotate in a direction generally indicated as D and stop at an angle of approximately 90 degrees relative to the longitudinal axis 116 of the body 102. This position of the dust cup 110 may be properly referred to as an open, release, or discard orientation. In the open orientation, the opening 148 may be used to allow, for example, dust and debris to exit the dust cup 110 and enter a trash can. Thus, the dust cup 110 may transition between, for example, a locked / closed orientation as shown in FIG. 1 and an open / discard orientation as shown in FIG. 3. When in the closed orientation, the dust cup 110 is in fluid communication with the filter of the filter section 108 via the opening 148. Meanwhile, when in the open orientation, the dust cup 110 is decoupled from fluid communication with the filter of the filter section 108, allowing the opening 148 to release / eject dust and debris accumulated within the dust cup 110.
[0014]
[0067] As discussed further below, the dust cup 110 may include cleaning or agitation elements (e.g., brush bristles) that agitate the filter within the filter section 108. Agitation of the filter within the filter section 108 frees trapped / clogged dirt and debris and generally promotes increased air fluid communication to ensure that clogging or otherwise reducing suction is prevented.
[0015]
[0068] Figure 4 illustrates an exemplary cross-sectional view of the handheld surface cleaning device 100 taken along line 4-4 of Figure 1. As shown, the body 102, and particularly the handle portion 104, defines a cavity 150 that can accommodate one or more power sources, such as batteries. The cavity may include a battery holder 128 or battery cradle 128 for positioning and aligning the battery with associated electrical contacts (not shown) for electrically coupling the battery to the motor 126. As mentioned above, the handle portion 104 provides a tapered region 146, which provides a transition between the handle portion 104 and the motor section 106.
[0016]
[0069] Continuing, the cavity 150 defined by the body 102 continues through the motor section 106. The motor section includes a motor 126 disposed within the cavity 150. After the motor section, the cavity 150 continues through the filter section 108. The filter 124 may then be disposed within the cavity 150 of the filter section. As shown, , filter 124 is a cone-type filter, although other filter devices are within the scope of this disclosure. Thus, cavity 150 can extend from a first end 140 at the base of handle portion 104 to a second end via dirty air inlet 120.
[0017]
[0070] Adjacent the filter section 108, a dust cup 110 couples to the filter 124. The dust cup 110 may thus be fluidly coupled to the filter section 108 by way of an opening 148. A screen 154 (see FIG. 6) may cover the opening 148 to prevent dirt and debris from entering into the motor section 106, which will be described in more detail below. As further shown, a dirty air inlet 120 is in fluid communication with the dust cup 110 for purposes of receiving and storing dirt and debris.
[0018]
[0071] A valve body 122 formed from a flexible or resilient material may be disposed between the dust cup 110 and the dirty air inlet 120. When the suction provided by the motor 126 is not being forced, the valve body 122 may remain in a valve seating position as shown in FIG. 4. The valve body 122 may be biased toward the dirty air inlet 120 based on spring tension, for example, based on a bend introduced into the material or other suitable arrangement. The seating position of the valve body 122 may form a seal, for example, an airtight seal that prevents 100% of the air flow, or a partial airtight seal that restricts at least 80% of the air flow, between the openings of the dust cup 110 that are aligned with the openings of the dirty air inlet 120, each generally indicated at 170. Thus, the seating position of the valve body 122 may prevent dust and debris from exiting the dust cup 110 through the openings aligned with 170 when the surface cleaning apparatus 100 is "off", for example, when there is no suction from the motor 126. The valve body 122 may be configured to be displaced / bend into the cavity 152 of the dust cup 110 when the suction force generated by the motor 126 draws air into the dirty air inlet and ultimately into the dust cup 110 .
[0019]
[0072] In one embodiment, when the dust cup 110 is in the release orientation, for example as shown in FIG. 3, the valve body 122 in the seated position continues to seal the cavity of the dust cup 110 based on, for example, a spring force biasing the valve body 122 away from the dust cup 110 and holding the cavity of the dust cup 110 against one or more defined surfaces, ensuring that dust and debris can only exit the dust cup 110 through the opening 145.
[0020]
[0073] With reference to FIG. 5, there is another exemplary embodiment of a dust cup suitable for use with the handheld surface cleaning device 100 of FIGS. 1-4. As shown, the dust cup includes an agitator member 155 in the form of a plurality of bristles. The bristles may be formed, for example, from plastic or other suitably rigid material. When in a closed position as shown in FIG. 6, the bristles 155 may be disposed adjacent to an upper surface 180 of the body 102 of the handheld surface cleaning device 100. As shown in the cross-sectional view of FIG. 6, the agitator member 155 contacts a screen 154 of the filter section 106 as the dust cup 110 rotates about an axis 160 to transition from a closed orientation to an open orientation. The screen 154 and the filter 124 may be collectively referred to herein as a filter arrangement. This contact, in a general sense, “scrapes” the screen 154 and may advantageously remove or displace debris adhering to the screen 154, minimizing or reducing loss of suction between the motor, filter, and dirty air inlet 120.
[0021]
[0074] The same scrubbing action can be achieved when transitioning the dust cup 110 from an open orientation to a closed orientation. To this end, each cleaning action of the dust cup 110 performed by a user can result in a two-stage cleaning action, whereby a first stage involves scrubbing the screen 154 along a first direction D1 when the dust cup 110 is released. A second stage involves scrubbing the screen 154 along a second direction D2 when the dust cup 110 transitions to a closed position. This includes scrubbing the screen 154 along direction D2 (see FIG. 7). In some cases, the user can release and close the dust cup 110 multiple times, resulting in a two-stage cleaning action to remove obstructions.
[0022]
[0075] 7, the filter section 106 may include a removable filter carriage 107 to allow the filter 124 to be replaced or otherwise cleaned. As shown, this embodiment includes the dust cup 110 being in a release orientation prior to removal of the removable filter carriage 107. Alternatively, or additionally, the entire filter carriage 107 and filter 124 may be replaced as a single, easy to use unit.
[0023]
[0076] 8 illustrates an embodiment of a vacuum cleaner 800 configured to removably couple to a handheld surface cleaning device 1. The handheld surface cleaning device 1 may be implemented as the handheld surface cleaning device 100 of FIG. 1, and this disclosure is not intended to be limited in this respect. As shown, the vacuum cleaner 800 includes a vacuum frame 802 (or simply frame 802), a collapsible joint 804, a handheld surface cleaner receptacle 806, a dust cup receptacle 808, a removable dust cup 810, and a cleaning head 812 with a dirty air inlet 814.
[0024]
[0077] The frame 802 defines a handheld surface cleaner receptacle 806 or handheld receptacle configured to securely hold the handheld surface cleaning device 1. When the handheld surface cleaning device 1 is placed / mounted within the handheld receptacle 806, the dirty air inlet 120 may be aligned and in fluid communication with a dirty air channel (not shown) that fluidly couples the dirty air inlet 814 with the dust cup 810. Thus, suction generated by the motor of the handheld surface cleaning device 1 may be used to draw air into the dirty air inlet 814. From there, the dirt and debris may then be stored within the dust cup 810 (or first dust cup) and / or the dust cup 110 (or second dust cup) of the handheld surface cleaning device 1.
[0025]
[0078] In some cases, the presence of dust cup 810 effectively increases the overall storage for dust and dirt (e.g., by more than double) compared to using dust cup 110 alone, although in some embodiments dust cup 110 may be utilized exclusively. As also shown, frame 802 includes an optional foldable joint 804 that allows an upper handle portion of frame 802 to be bent parallel to a lower portion having a hand-held receptacle 806 for storage purposes (see also FIGS. 34A-34C).
[0026]
[0079] 9 shows an embodiment of a dust cup 810 having a door 850 that may be hinged to the body 840 of the dust cup 810. In this example, a button can be pressed to release the door 850, allowing it to swing / swivel open and allow contained dirt and debris to exit the body 840 of the dust cup 810.
[0027]
[0080] 10 illustrates an exemplary embodiment of a docking system 4400 including a dock 4401, a handheld surface cleaning device 4402, and a robotic vacuum cleaner 4403. In one embodiment, the handheld surface cleaning device 4402 is implemented as, for example, the handheld surface cleaning device 100 of FIG. 1 or the handheld surface cleaning device 1 of FIG. 21. As shown, the dock 4401 includes a robotic vacuum cleaner coupling section defined at least in part by a base 4404, which is configured to removably couple to the robotic vacuum cleaner 4403. The base 4404 may further include electrical contacts / terminals for electrically coupling with the robotic vacuum cleaner 4403 for recharging purposes.
[0028]
[0081] The dock 4401 further includes a handheld surface cleaning device coupling section 4405, which may simply be referred to as a wand coupling section. The wand coupling section 4405 may include a wand receptacle 4406 and a wand release 4410 (or a wand release pedal 4410). As shown in the exemplary embodiment of FIG. 11, the wand receptacle 4406 (or receptacle) may be a recess / opening defined by a sidewall of the wand coupling section 4405. The wand receptacle 4406 may extend substantially perpendicular to a longitudinal axis 4408 of the dock 4401. The wand receptacle 4406 may be configured to at least partially receive the handheld surface cleaning device 4402. As shown, the wand receptacle 4406 includes a depth that allows a top surface 4409 of the hand-held surface cleaning device 4402 to be mounted flush with the surface 4401 that defines the wand receptacle 4406. Thus, the hand-held surface cleaning device 4402 may be relatively concealed when mounted in the wand receptacle 4406, and may have a contour that generally corresponds to the shape of the wand coupling section 4405.
[0029]
[0082] Inserting the hand-held surface cleaning device 4402 into the wand receptacle 4406 may include inserting the hand-held surface cleaning device 4402 at a first angle, for example, about 80 degrees. The nozzle of the hand-held surface cleaning device 4402 is used to bias and engage a spring loaded mechanism (not shown). Once inserted, the hand-held surface cleaning device 4402 may be locked in place via a detent (not shown) or other suitable locking mechanism.
[0030]
[0083] To remove the hand-held surface cleaning device 4402, a user-provided force (e.g., by the user's foot or hand) applied to the wand release 4410 releases the locking mechanism and allows the spring-loaded mechanism to transition the hand-held surface cleaning device 4402 from the stored position to the extended / release position. As shown, this transition may involve the hand-held surface cleaning device 4402 rotating about a first axis of rotation 4412 that extends substantially parallel to the longitudinal axis 4408. In the release position, the user can simply grasp the hand-held surface cleaning device 4402 and apply a force vertically away from the wand receptacle 4406 to separate it for use.
[0031]
[0084] FIG. 11 illustrates another exemplary embodiment of a docking system 4400a consistent with the present disclosure. The embodiment of FIG. 11 may also be accurately referred to as an upright configuration, where the handheld surface cleaning device 4402 extends vertically from the dock 4401a. More specifically, the dock 4401a includes a base 4404a and a wand coupling section 4405a. The base 4404a includes release buttons 4501 and 4502. The release buttons 4501 and 4502 may enable separation of the robotic vacuum cleaner 4403 and the handheld surface cleaning device 4402, respectively, based on a user-supplied force (e.g., from the user's foot). As shown, the release buttons 4501 and 4502 may at least partially define an incline that the robotic vacuum cleaner may move to be coupled to the dock 4401a.
[0032]
[0085] The wand coupling section 4405a may include a wand receptacle 4406a configured to at least partially receive the handheld surface cleaning device 4402. In particular, the wand receptacle 4406a may include an elongated cavity having a longitudinal axis that may extend substantially perpendicular to the longitudinal axis of the handheld surface cleaning device 4402. Thus, a handle section / region of the handheld surface cleaning device 4402 may extend at least partially from the wand receptacle 4406a when in the stored position.
[0033]
[0086] The wand coupling section 4405a may include a taper adjacent the robotic vacuum coupling section to provide a recess for at least partially receiving the robotic vacuum. The taper may thus form at least a portion of the robotic vacuum coupling section. When the robotic vacuum cleaner 4403 is coupled to the base 4404a, at least a portion 4503 of the wand coupling section 4405a may extend above the robotic vacuum cleaner 4403. This may advantageously reduce the overall footprint of the docking system 4400a when the robotic vacuum cleaner is in a stored position (i.e., coupled to the base 4404a).
[0034]
[0087] The user may then grasp the handle section / region of the handheld surface cleaning device 4402 and apply a force generally along direction D2 to separate it from the wand receptacle 4406a. In some cases, the user must first engage the release button 4502 to unlock the handheld surface cleaning device 4402 from the wand receptacle 4406a. In addition, the wand receptacle 4406a may include a spring-loaded mechanism that moves the handheld surface cleaning device 4402 upward along direction D2 in response to the user applying a force to release the release button 4502 while remaining at least partially within the wand receptacle 4406a. The direction D2 may extend substantially perpendicular to the longitudinal axis 4408a of the dock 4401a. This may advantageously reduce how far the user must reach to grasp the handheld surface cleaning device 4402.
[0035]
[0088] 12 illustrates another exemplary embodiment of a docking system 4400b in an upright configuration consistent with the present disclosure. As shown, this embodiment is substantially similar to that of docking system 4400a, and for the sake of brevity, its description will not be repeated. However, the docking system of 4400a includes a wand receptacle 4406b that does not have a locking mechanism, and may instead utilize a friction fit or simply gravity. Thus, the handheld surface cleaning device 4402 may be inserted / removed from the dock 4401b without actuating a release, e.g., release button 4502 (FIG. 11).
[0036]
[0089] 13a-d illustrate another exemplary embodiment of a docking system 4400c consistent with aspects of the present disclosure. As shown, the docking system 4400c includes a dock 4401c, a handheld surface cleaning device 4402, and a robotic vacuum 4403. The dock 4401c includes a base 4404b that defines a robotic vacuum coupling section. The wand coupling section 4401c includes a fixed portion 4703 rotatably coupled to a wand receptacle 4407b by a hinge 4702. The wand receptacle 4407b may thus rotate about a second axis of rotation 4412a between a stored position (FIGS. 13 / c / d) and a released position (FIG. 47a), each of which is discussed in more detail below.
[0037]
[0090] 13-13d, the wand receptacle 4407b may at least partially surround the hand-held surface cleaning device 4402. In a general sense, the wand receptacle 4407b may form a cradle that holds the hand-held surface cleaning device 4402 in a fixed position based on a friction fit connection, gravity, or both.
[0038]
[0091] As shown in Fig. 13a, when the wand receptacle 4407b is in the released position, the wand receptacle 4407b extends at approximately 45 ± 20 degrees relative to the longitudinal axis 4408b of the base, thereby allowing a user to easily reach and grasp the handheld surface cleaning device 4402. On the other hand, when the wand receptacle 4407b is in the stored position as shown in Fig. 13c, the wand receptacle 4407b extends substantially parallel to the longitudinal axis 4408b of the base.
[0039]
[0092] In one embodiment, the wand receptacle 4407b may transition between the stored and released positions via a hinge 4702 or other suitable coupling device that allows rotation about the second axis of rotation 4412a. The dock 4401c may include a mechanical mechanism (e.g., gears, belt drive, or other suitable mechanism) that causes rotation of the wand receptacle 4407b between the stored and released positions. The fixed portion 4703 may include a proximity sensor 4711, such as an infrared (IR) sensor. The proximity sensor 4711 induces a vertical IR field that, if violated by a user's hand (or other part), causes the wand receptacle 4407b to automatically rotate to the released position to facilitate removal of the handheld surface cleaning device 4402. The released position may also reveal or otherwise provide access to controls on the top surface of the robotic vacuum cleaner 4403 (see FIGS. 14a-c).
[0040]
[0093] Figures 14a-14c show the embodiment of Figures 13a-13d in additional detail. As shown, the dock 4401c may include an elongated leg 4802 that extends from the fixed section 4799 to a distance D1 that is at least 1.5 times the height H2 of the fixed section 4799. The elongated leg 4802 may thus advantageously support the wand receptacle 4407b (and handheld surface cleaning device 4402) in the absence of the robotic vacuum cleaner 4403.
[0041]
[0094] FIG. 15 illustrates another embodiment of a docking system 4400d consistent with aspects of the present disclosure. The docking system 4400d is similar to that of the docking system 4400a (FIG. 11), the disclosure of which will not be repeated for brevity. As shown, the wand coupling section 4405b includes an IR sensor (or other suitable proximity sensor), a wand receptacle 4407c having a tooth / detent (not shown), and an elevator / extension mechanism. The IR sensor may emit an IR beam adjacent to the dock 4401d. If the IR beam is violated (e.g., by a user's hand), a signal may be sent to the elevator / extension mechanism to cause it to extend upward along a vertical direction D3. The tooth / detent may engage a guide / track disposed along the length of the handheld surface cleaning device 4402, allowing it to move vertically along a relatively straight path. In one embodiment, this may cause the handheld surface cleaning device 4402 to elevate 6 inches to 8 inches, although other configurations are within the scope of the present disclosure. The IR sensor may further include a visual indicator (eg, an LED) to draw the user's attention to the location of the sensor.
[0042]
[0095] 15, the wand coupling section 4405b may be tapered (as shown in side profile) to offset the wand receptacle 4407c from the adjacent wall by a distance D4. This may advantageously allow a user to more easily reach around the handheld surface cleaning device 4402, even when the dock 4401d is positioned flush against a wall.
[0043]
[0096] 16a-16c collectively illustrate another embodiment of a docking system 4400e consistent with aspects of the present disclosure. As shown, the dock 4401e includes a wand receptacle 4407d adjacent a first end 5001 of the dock 4401e. As shown, the wand receptacle 4407d is integrally formed with the dock 4401e as a single monolithic piece. However, the wand receptacle 4407d and the dock 4401e may be formed as separate pieces depending on the desired configuration. The wand receptacle 4407d may include a curvilinear profile / shape to increase aesthetic appeal and to form a shape that generally corresponds to the shape of the handheld surface cleaning device 4402.
[0044]
[0097] As shown, the orientation of the wand receptacle 4407d is fixed. The handheld surface cleaning device 4402 disposed therein is held at an angle of approximately 45 degrees relative to the top surface 5002 that defines the dock 4401e. Other brush types are within the scope of this disclosure. The embodiment of Figures 16a-16c may be accurately referred to as a side-by-side configuration, whereby the wand receptacle 4407d is adjacent (e.g., disposed laterally) to the area where the robotic vacuum is coupled to the dock 4401e. Thus, when inserted into the wand receptacle 4407d, the handheld surface cleaning device 4402 includes a longitudinal centerline 4408d that is horizontally offset a distance D5 from the centerline 4408e of the robotic vacuum that is drawn against the dock 4401e, the distance D5 being at least equal to the radius R1 of the robotic vacuum.
[0045]
[0098] FIG. 17 illustrates another embodiment of a docking system 4400f consistent with aspects of the present disclosure. As illustrated, the embodiment of FIG. 51 is similar to that of the docking system 4400e of FIG. 50, and for this reason, the description will not be repeated for brevity. As shown, the dock 4401f includes a wand coupling section 4405c including a robot coupling section 4420c and a wand receptacle 4407e in a side configuration. The wand coupling section 4405c further includes an IR sensor 5102 (or other suitable proximity sensor). In response to a user violating the IR beam emitted by the IR sensor 5102, a signal can be sent to the wand receptacle 4407e. A lift and tilt mechanism (not shown) can then receive the signal and transition the handheld surface cleaning device 4402 from the stored position 5105 to the released position 5106. As shown, the transition to the release position 5106 causes the handheld vacuum cleaner 4402 to first move along a vertical path relative to the top surface of the robotic vacuum cleaner (e.g., away from the robotic vacuum cleaner). It then "tilts" the handheld vacuum cleaner 4402 towards the robotic vacuum cleaner, e.g., at an angle of about 70±15 degrees relative to the robotic vacuum cleaner. Meanwhile, the transition to the stowed position 5105 causes the reverse of the transition to the release position 5106, e.g., tilting back vertically and then moving downward towards the robotic vacuum cleaner.
[0046]
[0099] If no user is detected, for example when the user moves away from the dock 4401f, the lift and tilt mechanism may automatically transition to return the hand-held surface cleaning device to the stored position 5105. This advantageously allows the user to insert the hand-held surface cleaning device 4402 into the wand receptacle 4407e and simply move away, while the wand receptacle 4407e moves back to the stored position 5105.
[0047]
[0100] The following additional embodiments and examples are equally applicable to the present disclosure. For example, the handheld surface cleaning device 1 of Figure 21 may be utilized in the various embodiments disclosed above. This includes, for example, a base (see Figures 10-20b) that may be utilized to couple to both robotic and handheld cleaning devices.
[0048]
[0101] FIG. 21 shows a perspective view of a handheld surface cleaning device 1 according to an embodiment of the present disclosure. As shown, the handheld surface cleaning device 1 includes a body 2 coupled to a cleaning head 3. An optional flexible region 4, also referred to as a flexible conduit, couples the body 2 to the cleaning head 3 and allows the cleaning head 3 to rotate relative to the body 2 during a cleaning operation. A dirty air passageway 14 can extend from a dirty air inlet 11 provided by the cleaning head 3, through the cleaning head 3 and the body 2, to a dust cup 23 (see FIGS. 22A and 22B) disposed adjacent a distal end of the body relative to the cleaning head 3. Thus, the body 2 and the cleaning head 3 can be in fluid communication to receive dirt and dust via the dirty air passageway.
[0049]
[0102] The body 2 extends along a first longitudinal axis 9 from a first end 10-1 to a second end 10-2. 3. Body 2 may have a substantially cylindrical shape as shown, although other shapes (e.g., rectangular, square, irregular, etc.) and configurations are within the scope of this disclosure. Body 2 may be formed from plastic or other suitably rigid material. Body 2 may include multiple pieces or may be formed from a single piece. As shown, body 2 includes a removable piece for separating dust cup portion 6 from power supply and motor portion 8.
[0050]
[0103] The body 2 may be defined by a surface 5, also referred to as a handgrip surface 5. The body 2 may be contoured to comfortably fit a user's hand during use. Thus, the handgrip surface 5 may extend at least partially around the power supply and motor portion 8 and the dust cup portion 6.
[0051]
[0104] The body 2 may include a power source and motor portion 8 disposed proximate the first end 10-1 followed by the dust cup portion 6. As discussed in more detail below, the components within the power source and motor portion 8 (e.g., one or more motors and one or more power sources such as batteries) may be disposed coaxially with the dust cup portion 6 of the body 2. Because the power source and motor portion 8 is disposed forward (e.g., upstream) of the dust cup portion 6, the components of the power source and motor portion 8 collectively define a cavity extending therethrough that allows dirty air traveling along the dirty air passageway 14 to reach the dust cup portion 6 for storage purposes.
[0052]
[0105] The body 2 may include vents 7 located proximal to the second end 10-2 to allow filtered / clean air to exit the body 2. The vents 7 may be located proximal to the second end 10-2 to ensure that a user's hands do not inadvertently cover the vents 7 during operation. Other locations of the vents 7 are within the scope of this disclosure and the example illustrated in FIG. 21 should not be construed as limiting.
[0053]
[0106] 21, the cleaning head 3 may extend along a second longitudinal axis 15 from a first end 12-1 to a second end 12-2. The cleaning head 3 may be formed from the same material as the body 2 or may comprise a different material. In some cases, the cleaning head 3 is formed from a bendable material, e.g., a material that bends / does not bend based on a user-supplied force. In other cases, the cleaning head 3 is formed from a relatively rigid material that resists bending. In still other cases, the cleaning head 3 is formed from multiple materials. For example, the first end 12-1 adjacent the dirty air inlet 11 may be formed from a relatively rigid material and the second end 12-2 may be formed from a relatively rigid material.
[0054]
[0107] In some cases, the first longitudinal axis 9 of the body 2 may be substantially parallel to the second longitudinal axis 15, for example for storage purposes, docking purposes, or if a user desires the cleaning head 3 to extend straight out from the body 2. In other cases, as shown, the second longitudinal axis 15 of the cleaning head 3 may extend at an angle 17 relative to the first longitudinal axis 9, the angle 17 being between 1 degree and 180 degrees, preferably between 30 degrees and 90 degrees.
[0055]
[0108] As further shown, the dirty air inlet 11 is disposed at the first end 12-1. The dirty air inlet 11 may define an opening having a width W1 and a height H1. The ratio of W1 to H1 may measure, for example, about 2:1, 3:1, 4:1, 10:1, 15:1, including all ranges therebetween. The ratio of the overall length L1 to the width W1 may measure, for example, about 1:1, 1.25:1, 1.5:1, 2:1, including all ranges therebetween. Other ratios are within the scope of this disclosure, and the examples provided are not intended to be limiting. The width W1 of the dirty air inlet 11 may be greater than the width W2 of the cleaning head 3 proximate the second end 12-2. Thus, the cleaning head 3 may taper inwardly from the first end 12-1 to the second end 12-2. However, the cleaning head 3 is not necessarily tapered as illustrated. The width of the longitudinal axis 15 need not necessarily be spaced apart, but may include a substantially continuous width along the longitudinal axis 15.
[0056]
[0109] The handheld surface cleaner may further include a flexible region 4 (or flexible conduit) disposed between the main body 2 and the cleaning head 3. In particular, a first end of the flexible region 4 may be coupled to a second end 12-2 of the cleaning head 3. A second end of the first end of the flexible region 4 may be coupled to the first end 10-1 of the main body 2. The flexible region 4 may include a cavity that defines at least a portion of the dirty air passageway 14.
[0057]
[0110] The flexible region 4 may be formed from a plastic or other bendable material that can bend based on a user-supplied force. The flexible region 4 may be configured to return to a particular resting state in the absence of a user-supplied force. For example, the flexible region 4 may return to an unbent state in which the first and second longitudinal axes 9 and 15 of the body 2 and cleaning head 3 extend substantially parallel. In other cases, the flexible region 4 may be configured to remain in a bent position, e.g., via a clip or other mechanical retention feature, until a user supplies a force to transition the cleaning head to another position relative to the body 2.
[0058]
[0111] In either event, the flexible region 4 allows the cleaning head 3 to rotate relative to the body 2. In some cases, as discussed above, the flexible region 4 may allow for an angle 17 measuring between 0 degrees and 180 degrees. Preferably, the flexible region 4 allows for a maximum rotation of 90 degrees.
[0059]
[0112] In some cases, rotation of the cleaning head 3 relative to the body 2 switches the handheld surface cleaner on. For example, when a user wishes to clean a particular surface, the user may automatically turn on the handheld surface cleaner 1 by simply engaging the cleaning head 3 with the surface and applying a force that causes the flexible region 4 to bend. In response to the bending of the flexible region 4, the handheld surface cleaner 1 may provide power to the motor to introduce suction along the dirty air passageway 14. Similarly, the absence of force applied by the user will cause the handheld surface cleaner 1 to be switched off.
[0060]
[0113] Alternatively, or in addition to the auto-on feature described above, the main body 2 may include a button or other suitable control (not shown) that allows the handheld surface cleaner 1 to be manually turned on and off.
[0061]
[0114] It should be noted that the flexible region 4 is optional. For example, the body 2 may simply be directly coupled to the cleaning head 3. Alternatively, the flexible region 4 may also be replaced with a rigid portion (or rigid conduit) that does not bend based on user-supplied force.
[0062]
[0115] In any such case, the body 2 and / or cleaning head 3 may be removably coupled to the flexible region 4. Thus, a user may remove the body 2 and / or cleaning head 3 from the flexible region 4 to, for example, avoid clogging the dirty air passage 14 or to attach a different type of cleaning head 3, such as a cleaning head comprised of brush bristles.
[0063]
[0116] 22A, in accordance with an embodiment of the present disclosure, the body 2 is shown separated from the cleaning head 3 and the flexible region 4. The body 2 is shown in greatly simplified form, and other components may be disposed within the body 2. As shown, the body defines a cavity 19. The body 2 further includes a motor 20, a power source 22, and a dust cup 23 disposed within the cavity 19. Each of the motor 20, the power source 22, and the dust cup 23 may include a longitudinal axis that is substantially parallel to the longitudinal axis 9. Thus, the motor 20, the power source 22, and the dust cup 23 may be coaxially disposed within the cavity 19. As will be described below, this The coaxial arrangement allows the motor 20, power supply 22, and dirt cup 23 to align their respective cavities and collectively form a single dirty air passage, such as dirty air passage 14. The coaxial arrangement may form multiple dirty air passages depending on the desired configuration, and the present disclosure should not be construed as limited to a single passage.
[0064]
[0117] The motor 20 may include, for example, a brushless DC motor, although other types of motors are within the scope of this disclosure. The motor 20 may be electrically coupled to a power source 22 and / or an AC line via a charging circuit, as discussed further below. The motor 20 may include a cavity 52 (see FIG. 23C) to allow the dirty air passage 14 to extend therethrough. The motor 20 may include an impeller / fan 50 that directs airflow / suction toward the dust cup 23.
[0065]
[0118] 23C and 23B show motor 20 in further detail according to an embodiment of the present disclosure. As shown, motor 20 may be constructed within fan 50 disposed within cavity 52. Motor 20 further includes openings / vents 51 along sidewalls 53 to regulate air flow.
[0066]
[0119] Returning to FIG. 22A, the power source 22 may include a plurality of battery cells 29. In one embodiment, each battery cell is a lithium ion battery cell, although other types of battery cells are within the scope of the present disclosure. As shown in the power source 22A in FIG. 23A, each of the plurality of battery cells 29 may form an annular arrangement. The annular arrangement may include a cavity 32 extending therethrough. In the annular arrangement, each battery cell may have a respective longitudinal axis substantially parallel to the longitudinal axis 9 of the body 2 when the power source 22A is disposed therein. FIG. 23B illustrates another exemplary power source 22B configured as a ring-shaped capacitor. The ring-shaped capacitor may also include a cavity 33 extending therethrough. In such a case, the power source 22 may at least partially define the dirty air passage 14 based on the associated cavity. Thus, a cavity of the power source 22, such as cavity 32 or 33, may be aligned with the motor cavity 52 when the power source 22 and cavity 52 are disposed within the cavity 19 of the body 2.
[0067]
[0120] Returning to FIG. 22A, the power source 22 may be charged via an associated charging circuit (not shown). The charging circuit may include, for example, an induction coil for receiving an electrical charge for the purposes of charging the power source 22. Alternatively, or additionally, the charging circuit may include a terminal or other suitable interconnect (e.g., a USB-C port), for example, to couple to a base / docking station for charging purposes. The charging circuit may also allow power from the mains to be used directly by the handheld surface cleaning device 1 while charging the power source 22.
[0068]
[0121] Figure 22B illustrates a body 2' of substantially similar configuration to that of the body 2 of Figure 22. For this reason, the foregoing description is equally applicable to the body 2' and will not be repeated for the sake of brevity. However, the body 2' includes a power source 22 disposed prior to the motor 20. Thus, the body 2' includes a power source 22 disposed proximate the first end 10-1 of the body 2, followed by the motor 20, followed by the dust cup 23.
[0069]
[0122] The bodies 2 and 2' of Figures 22A and 22B, respectively, may include multiple power sources 22 and / or multiple motors 20 disposed and aligned within the cavity 19 to form the dirty air passageway 14. Thus, while the above examples illustrate a single motor and power source, the disclosure is not limited in this respect. Similarly, while each motor, power source, and dust cup has a substantially cylindrical shape, the disclosure is not limited in this respect. Other shapes and configurations are within the scope of the disclosure.
[0070]
[0123] 23C-23D, the dust cup 23 may be configured to receive and store dust and debris received from the dirty air passageway 14. The dust cup may define a cavity 40 for storing the dust and debris. The dust cup may further include an electrostatic charge accumulator 41 that serves to attract and capture the dust and debris. In some cases, the electrostatic charge accumulator 41 is formed from a material that naturally tends to hold a static charge. Alternatively, or additionally, the electrostatic charge accumulator 41 may be energized, for example, via the power source 22.
[0071]
[0124] 24A-24C show additional exemplary embodiments consistent with the present disclosure. As shown in FIG 24B, the handheld surface cleaning device can be docked to a base for recharging purposes.
[0072]
[0125] FIG 25 illustrates an exemplary handheld surface cleaning device consistent with the present disclosure. FIG 26A illustrates a cross-sectional view of the handheld surface cleaning device of FIG 25 according to an embodiment of the present disclosure. FIG 26B illustrates an exemplary cleaning head of the handheld surface cleaning device of FIG 25 according to one embodiment of the present disclosure. FIG 26C illustrates an exemplary handle of the handheld surface cleaning device of FIG 25 according to one embodiment of the present disclosure.
[0073]
[0126] 27 illustrates another exemplary handheld surface cleaning device consistent with the present disclosure. As shown in FIG. 27, the handle portion may rotate relative to the body to transition / articulate into one or more positions. The battery may be located within the handle portion as shown in cross section along AA, which allows the handle portion to have a relatively low profile form factor throughout its length.

[0076]
[0129] 30A-30C show additional exemplary embodiments of a surface cleaning device consistent with embodiments of the present disclosure. As shown, the dust cup can be extended to increase storage capacity.
[0077]
[0130] 31A-31D, an exemplary surface cleaning apparatus 1300 is shown in accordance with an embodiment of the present disclosure. As shown, the surface cleaning apparatus 1300 includes a body 1301 and a dust cup 1302 coupled to a first end 1319 of the body 1301. Aspects and embodiments described above with reference to Figures 1-20B and 21-30C equally apply to the surface cleaning apparatus 1300 and will not be repeated for the sake of brevity.
[0078]
[0131] As generally referred to herein, the terms "closed position" and "docked position" may be used interchangeably and refer to the position of the dust cup 1302 relative to the body 1301 whereby the dust cup 1302 is coupled to and in fluid communication with the body 1301, and more particularly, the motor 1322 disposed within a cavity of the body 1301 that generates a suction force that draws dirt and debris into the dust cup 1302. In some cases, the closed position may result in the dust cup 1302 having a longitudinal axis that extends substantially parallel to the longitudinal axis of the body 1301, as shown in FIG.
[0079]
[0132] Conversely, the terms "open position" or "empty position" are used interchangeably and refer to the position of the dust cup 1302 relative to the body 1301, whereby the dust cup 1302 is tilted substantially vertically relative to the body 1301 to allow for emptying of the dust cup. The dust cup 1302 may be rotatably / pivotally coupled to the body 1301 such that the dust cup 1302 may transition to the open position. This transition may be initiated, for example, by a button 1305 located on the body 1301, which is discussed in more detail below. Thus, when in the open position, the dust cup may be fluidly isolated from the motor 1322 while remaining pivotally and rotatably coupled to the housing.
[0080]
[0133] As discussed in more detail below, the dust cup 1302 may be spring loaded to deflect / bring it to the open position. The body 1301 may provide a stop, e.g., a side wall 1340 (FIG. 31B) or other surface feature, to engage the dust cup 1302 while rotating due to the release of spring tension. Engaging the stop may then cause the dust cup 1302 to abruptly stop its rotational motion, the impact of which may advantageously dislodge the dirt and debris stored within the dust cup 1302. Gravity may then be used to dislodge the dirt and debris from the dust cup opening located at the opposite end to the inlet opening that receives the dirty air. The spring bias may then hold the dust cup 1302 in the open position until the user desires for the dust cup 1302 to transition back to the closed position. Thus, a user can empty the dust cup 1302 by simply tilting the handheld surface cleaning device 1300 over the mouth of a dust bin and transitioning the dust cup 1302 to an open position, for example via actuation of the button 1305.
[0081]
[0134] Additionally, and according to an embodiment, the filter arrangement 1314 may be at least partially disposed within the body 1301. The filter arrangement 1314 may also be spring loaded and "deflected" forward (see FIGS. 31B and 31D) to extend at least partially from the body 1301 and stop at a predetermined distance D1. In this embodiment, the filter arrangement 1314 may move a distance D1 from the body 1301 before encountering a stop, such as a wrap, catch, or other protrusion on the interior or exterior of the body 1301, such as protrusion 1398 (see FIG. 31B) (after the dust cup 1302 has rotated away from the filter arrangement 1314). The spring bias may then hold the filter arrangement 1314 in the extended position until the dust cup 1302 displaces the filter arrangement 1314 when it returns to the closed position, such as based on a user-provided force.
[0082]
[0135] Thus, the surface cleaning device 1300 can be accurately described as having a multi-phase (or multi-step) opening sequence based on a single user-supplied motion. In response to a single user-supplied motion (e.g., pressing a button), the dust cup first snaps / springs / activates forward (longitudinally), then rotates to a vertical / upright position, and then the filter arrangement snaps / springs out simultaneously with or shortly after the dust cup transitions (e.g., based on the spring of the filter arrangement 1314 having a different spring constant / configuration than the spring associated with the dust cup 1302). Of note, the dust cup 1302 can be weighted to induce the upright position (see FIG. 31B). Alternatively or additionally, the dust cup 1302 can be brought to the upright position based on a track provided by the body 1301 that causes the rotation. It should be noted that the dust cup 1302 may be configured with an agitation device, e.g., bristles, similar to those of the dust cup 110 of FIG. 5, and the embodiments disclosed above are equally applicable to the handheld surface cleaning devices of FIGS. 31A-31D.
[0083]
[0136] Continuing with FIG. 31A to FIG. 31D, a motor 1322 is disposed in a main body 1301 and is used The dust cup 1302 generates suction that draws dirty air into the inlet 1309 (or nozzle) via the dirty air passage 1330 (see FIG. 31C) during operation. The dust cup 1302 and more specifically the dirty air passage 1330 may be in fluid communication with the motor 1322 when the dust cup 1302 is in a closed position as shown in FIG. 13A. A filter 1311 disposed between the body 1301 and the dust cup 1302 may prevent / reduce dust and debris from entering the body 1301 and eventually clogging the motor 1322. The dust and debris may then be stored in a dust storage area 1331 (FIG. 31C) within a cavity of the dust cup 1302 during operation of the surface cleaning apparatus 1300.
[0084]
[0137] In one embodiment, the dust cup 1302 may be disengaged from the suction of the motor 1322 when in an open position based on rotation of the dust cup 1302 relative to the body 1301. For example, as shown in FIG. 31B, an end of the dust cup 1302 may be disengaged from the body 1301 and rotated to angle the dust cup 1302 substantially transversely relative to the body 1301. As shown in FIG. 31D, the open position of the dust cup 1302 may result in the dust cup 1302 having a longitudinal axis 1316 that is substantially transverse to the longitudinal axis 1315 of the body. The angle at which the dust cup 1302 extends relative to the body 1301 may vary, for example, from 15 degrees to 180 degrees, preferably from 15 degrees to 90 degrees, depending on the desired configuration.
[0085]
[0138] In one embodiment, the body 1301 may be formed from plastic, metal, and / or any other suitable rigid material. The body 1301 may be formed from a single piece of material, or may be formed from multiple pieces.
[0086]
[0139] The body 1301 may be defined by a wall extending along a longitudinal axis 1315 from a first end 1319, referred to as a dust coupling end 1319, to a second end 1320. The wall may be defined by a surface 1306, which provides a handle portion, or handle, that may be comfortably grasped in a user's hand during operation of the surface cleaning device 1300.
[0087]
[0140] The body 1301 further includes a button 1305 for transitioning the dirt cup 1302 from a closed position, e.g., as shown in Fig. 31A, to an open position, e.g., as shown in Fig. 31B. The button 1305 is not necessarily limited to being a mechanical button that a user presses to transition the surface cleaning device 1300 from the closed position to the open position. For example, the button 1305 could also be any other suitable user input device, such as a slider button, a capacitive touch button, a rotatable ring that extends around a diameter of the body 1301, and the like.
[0088]
[0141] The body 1301 can define a cavity 1321 (FIG. 31C). The cavity can include a filter arrangement 1314, a motor 1322, and a power source 1323 disposed therein. The motor 1322 can include, for example, a brushless DC motor, although other types of motors are within the scope of the present disclosure. The motor 1322 can be electrically coupled to the power source 1323 and can generate suction to draw dirt and debris into the dust cup 1302.
[0089]
[0142] The dust cup 1302 may comprise plastic, metal, or any other suitable rigid material. The dust cup 1302 may be defined by one or more walls extending along a longitudinal axis 1316 from a first end 1309 (or nozzle) to a second end 1350 (suction coupling end or suction coupling section) (FIG. 31D). The dust cup 1302 further defines a cavity having a dirty air passageway 1330 extending at least partially therethrough, the dirty air passageway extending substantially parallel to the longitudinal axis 1316. The dust cup 1302 further defines a dust containment area within the cavity for receiving and storing dirt and debris. The dust cup 1302 includes a dust storage area 1331. The walls surrounding the dust storage area 1331 may be optically transparent, for example, allowing 80% or more of the incident visible wavelengths, allowing a user to visually inspect the current amount of dirt and debris stored in the dust storage area through the walls. The suction coupling end 1350 also provides an opening for releasing dirt and debris when the dust cup 1302 is oriented upright / vertically in the open position.
[0090]
[0143] The filter arrangement 1314 includes a cylindrical housing that generally corresponds to the shape of the body 1301. Other shapes and configurations of the filter arrangement 1314 are within the scope of this disclosure. The filter arrangement 1314 may include one or more filters, such as the pleated filter 1311 shown in FIG. 31C. The filter or filters may include, for example, a polyester material, PTFE, fiberglass, or any other suitable filter material. The filter or filters may include a cartridge body to facilitate removal and replacement of the filter.
[0091]
[0144] The filter arrangement 1314 may further include a spring 1324 for biasing the filter arrangement 1314 away from the body 1301 and towards the dust cup 1302. When the dust cup 1302 is in the closed position as shown in Figures 31A and 31C, the spring 1324 may be compressed against the dust cup 1302, displacing the filter arrangement 1314 towards the cavity 1321 of the body 1301. It should be noted that the spring 1324 may include fewer springs (e.g., a single spring) depending on the desired configuration.
[0092]
[0145] Subsequently, the arms 1308-1 and 1308-2 (or arm portions) may extend from the body 1301 along the longitudinal axis 1315. The arms 1308-1, 1308-2 may be integrally formed with the body 1301 as a single monolithic piece, or may be formed from multiple pieces. In one embodiment, the arms 1308-1 and 1308-2 may be formed from the same material as the body 1301, for example, plastic or other suitable rigid material. In some cases, the arms 1308-1 and 1308-2 may be formed from a different material than that of the body 1301. For example, the arms 1308-1 and 1308-2 may be at least partially formed from a metal or metal alloy to reinforce the arms.
[0093]
[0146] Arms 1308-1 and 1308-2 may each be pivotally coupled to dust cup 1302 to permit rotational movement along a direction / path generally indicated as D ( FIG. 31B ). Thus, dust cup 1302 may pivot / rotate relative to arms 1308-1 and 1308-2 about an axis of rotation 1325, which is substantially perpendicular to longitudinal axis 1315.
[0094]
[0147] The arms 1308-1 and 1308-2 may further define a cavity. The cavity defined by the arms 1308-1 and 1308-2 may include a spring 1307. Each of the springs 1307 may bias the dust cup 1302 away from the body 1301, for example, by providing a force to the dust cup carrier 1326 or other mechanism coupled to the dust cup 1302. The dust cup carrier 1326 may be formed integrally with the dust cup 1302, i.e., as a single monolithic piece, or may be formed from multiple components. The dust cup carrier 1326 is configured to move longitudinally along a track / guide provided by the arms 1308-1 and 1308-2. Thus, the dust cup carrier 1326 may be used to transition / displace the dust cup 1302 from a closed position to an open position.
[0095]
[0148] Detents 1399 (FIG. 31B) or other suitable locking mechanism may extend from the surfaces of arms 1308-1 and 1308-2 to securely hold the dust cup carrier 1326, and thus the dust cup 1302, in the closed position. 99 may be spring-loaded and configured to engage a corresponding surface feature of the dust cup 1302, such as a catch / recess 1327. Thus, when the dust cup 1302 is pressed into alignment with the filter arrangement 1314, based on, for example, a user-supplied force, the detent 1399 can engage with the catch 1327 of the dust cup 1302 to securely hold the dust cup 1302 in place relative to the body 1301.
[0096]
[0149] To release the dust cup 1302 to the open position, a user may press a button 1305. Pressing the button 1305 may include using a pinching motion with a thumb and index finger against a button located on opposite sides of the body 1301. In response, the button 1305 may mechanically actuate a detent 1399 to disengage it from a catch in the dust cup 1302. Alternatively, the button 1305 may provide an electrical signal that is used, for example, by a motor or other mechanical actuator to release the detent 1399.
[0097]
[0150] In any event, the button 1305 may thus enable a user to transition the dust cup 1302 to an open position to empty the dust cup and clean the filter of dust and debris. The dust cup 1302 may include a recessed surface 1339 (see FIG. 31B ) or recessed area 1339 that defines a sidewall 1341. The sidewall 1341 extends substantially perpendicular to the surface 1339. The sidewall 1341 may be configured to engage with a stop surface 1340 on the arms 1308-1 and 1308-2 to prevent rotational movement of the dust cup 1302 beyond a predetermined limit (e.g., 90 degrees). The impact of the dust cup 1302 encountering the stop surface 1340 may advantageously release dirt and debris within the dust cup 1302.
[0098]
[0151] 31D , the filter arrangement 1314 may include a protrusion / catch / surface 1344 for engaging a corresponding stop / protrusion 1398 on the body 1301. The dust cup 1302 may include a recessed area / guide 1340 for engaging the protrusion 1398. Thus, the protrusion 1398 may be used to align and guide the dust cup 1302 with the body 1301 as the dust cup 1302 transitions back to the closed position.
[0099]
[0152] In one embodiment, the surface cleaning apparatus 1300 can be held in one hand and transitioned from the closed position to the open position by that hand.
[0100]
[0153] Figures 32A-32D collectively illustrate the handheld surface cleaning device 1300 transitioning from a closed position to an open position. In particular, Figure 32A illustrates the handheld surface cleaning device 1300 in a closed position, whereby the dust cup 1302 is in fluid communication with a motor disposed within the body 1301, according to an embodiment of the present disclosure.
[0101]
[0154] FIG 32B illustrates the handheld surface cleaning device 1300 after one or both of the buttons 1305 on either side of the body 1301 have been pressed by a user, according to one embodiment of the present disclosure. In response to the push button 1305 being pressed, the detent 1399 (FIG. 31B) may disengage from the dust cup 1302. Similarly, and as shown in FIG 32C, the dust cup 1302 and filter arrangement 1314 may move longitudinally away from the body 1301. In some cases, there may be a momentary pause between the rotational movement of the dust cup 1302 and the movement of the filter arrangement 1314, depending on the desired configuration.
[0102]
[0155] As shown in FIG. 32D, the dust cup 1302 may rotate / pivot relative to the body 1301 and may stop in a position that holds the dust cup 1302 in an orientation that is substantially transverse to the body 1301. The dust cup 1302 may pivot based on tracks / guides provided by the arms 1308-1 and 1308-2. Alternatively, As well as, or in addition, weight may be added to the dust cup 1302 to tend it naturally towards a vertical / upright orientation.
[0103]
[0156] The dust cup 1302 may be held in this position based at least in part on a spring 1307 disposed on the first and second arms 1308-1 and 1308-2 (see FIG. 31B). Similarly, the filter arrangement 1314 may be held in the extended position based on a spring bias from a spring 1324. Thus, the user may then shake the handheld surface cleaning device 1300 to empty the dust and debris from the dust cup 1302. To place the dust cup 1302 in a closed position for further use, the user may rotate the dust cup 1302 into alignment with the body 1301 and then slide the dust cup 1302 towards the body 1301 to move the filter arrangement 1314 and "lock" it into the closed position based on a detent 1399 that engages a sidewall feature of the dust cup 1302, e.g., recess 1327.
[0104]
[0157] FIG. 33 illustrates an additional exemplary embodiment of a surface cleaning apparatus consistent with embodiments of the present disclosure.
[0105]
[0158] 34A-34C illustrate additional exemplary embodiments of a surface cleaning apparatus consistent with embodiments of the present disclosure. It should be noted that the exemplary aspects illustrated in FIG. 34A-34C are equally applicable to the embodiment illustrated in FIG.
[0106]
[0159] 35-35B illustrate additional exemplary embodiments of a surface cleaning apparatus consistent with embodiments of the present disclosure.
[0107]
[0160] 36A-36B illustrate additional exemplary embodiments of a surface cleaning apparatus consistent with embodiments of the present disclosure.
[0108]
[0161] 37-45 show additional exemplary embodiments of a handheld surface cleaning device 1900 having a body 1901 including a handle 1907, an expandable crevice tool 1902, a cyclone assembly 1904, and a motor 1912 electrically coupled to at least one battery 1905. The battery 1905 may be stored within the handle 1907. As shown, the cyclone assembly 1904 includes an inlet 1906 fluidly coupled with the crevice tool 1902, a vortex finder 1908, a collection area 1910, and a filter 1914. During operation, air is drawn from the crevice tool inlet 1916 into the cyclone assembly 1904. The air may include, for example, dust collected during a cleaning operation. Dust carried in the air may be collected within the cyclone assembly 1904 (e.g., in the collection area 1910).
[0109]
[0162] When a sufficient amount of dust is collected within the cyclone assembly 1904, an operator may empty the dust by opening a door 1918. When the door 1918 is opened, the dust may exit the cyclone assembly 1904 (e.g., by gravity). An operator may open the door 1918 by actuating a button (or trigger) 1920. In some instances, actuation of the button 1920 may result in movement of a push rod 1922. As the push rod 1922 moves between the first and second positions, the push rod 1922 may engage a latch 1924 that holds the door 1918 in a closed position. As shown, as the latch 1924 moves out of engagement with the door 1918, the door 1918 rotates about an axis 1926.
[0110]
[0163] Once released, the operator can re-close the door 1918 by returning the door 1918 to engagement with the latch 1924. Additionally or alternatively, the user can actuate the button 1920 (or actuate or trigger a different button) to a second position to close the door 1918. In some instances, the latch 1924 can include a biasing member (e.g., a spring) that biases the latch 1924 toward an engaged position (e.g., a position where the latch 1924 can engage the door 1918).
[0111]
[0164] The gap tool 1902 may be extendable from a first position to a second position. For example, an operator may manually grasp the gap tool 1902 and transition the gap tool 1902 between the first and second positions by pulling (or pushing) the gap tool 1902. Additionally or alternatively, the gap tool 1902 may transition between the first and second positions in response to actuation of a button (or trigger).
[0112]
[0165] Also, as shown, at least a portion of the cyclone assembly 1904 may be removably coupled to the body 1901 of the handheld surface cleaning device 1900. For example, removal of the cyclone assembly 1904 may allow a user to clean and / or replace the filter 1914. By way of further example, in some examples the vortex finder 1908 may be removable. As shown, a tip at feature 1917 may be provided for coupling the cyclone assembly 1904 to the body 1901.
[0113]
[0166] In some instances, the handheld surface cleaning device 1900 may be used in a robotic vacuum system. For example, the handheld surface cleaning device 1900 may be used to remove dust from a robotic vacuum.
[0114]
[0167] According to one aspect, a handheld surface cleaning device is disclosed that includes a body extending from a first end to a second end, a handle portion defined by the body adjacent the first end, a nozzle having a dirty air inlet defined by the body adjacent the second end, a motor for generating suction and drawing air into the dirty air inlet, and a dust cup for receiving and storing dust and debris, the dust cup rotatably coupled to the body of the handheld surface cleaning device and configured to transition between a closed orientation that fluidly couples the dust cup to the dirty air inlet and the motor and a release orientation that decouples the dust cup from the dirty air inlet and the motor to allow dirt and debris stored in the dust cup to exit an opening in the dust cup.
[0115]
[0168] According to another aspect, a docking system is disclosed. 1. A docking system comprising: a dock including a robotic vacuum coupling section; a handheld surface cleaning device including a body extending from a first end to a second end, a handle portion defined by the body adjacent the first end, a nozzle having a dirty air inlet defined by the body adjacent the second end, a motor for generating suction and drawing air into the dirty air inlet, and a dust cup for receiving and storing dirt and debris, the dust cup rotatably coupled to the body of the handheld surface cleaning device and configured to transition between a closed orientation that fluidly couples the dust cup to the dirty air inlet and the motor and a release orientation that decouples the dust cup from the dirty air inlet and the motor to allow dirt and debris stored in the dust cup to exit an opening in the dust cup; and a receptacle defined by the dock that receives and couples the first end of the handheld surface cleaning device and extends a second end defining the handle portion away from the dock.
