[0044] Cleaning surfaces, such as hard floors or carpets, can be challenging when various types of debris and spills are present, such as wet, dry, or mixed media. Cleaning devices are generally suitable for cleaning dry or wet debris, but not both. Therefore, users often need to use multiple cleaning devices to clean their floors. For example, a user might use a broom and / or vacuum cleaner to remove dry debris and then use a mop to clean wet spills and / or remove stains. In some cases, even with the same type of debris, users may need to use multiple cleaning devices. For example, a vacuum cleaner may successfully pick up large particles but may not be able to capture smaller dust particles. Using multiple cleaning devices can be time-consuming. For example, a user may not only need to use multiple cleaning devices, but may also need to use the same cleaning device multiple times to thoroughly clean the floor. For example, a user may need to sweep the floor before mopping and / or vacuum the floor and then sweep and / or vacuum the floor again after mopping, for example, to pick up debris that was not removed from the surface before mopping or to pick up dirt or debris that formed during mopping.

[0045] Using multiple cleaning devices can be cumbersome and / or require lengthy setup times or post-use maintenance. For example, in some situations, users may prefer a broom over a vacuum cleaner because it's more convenient than setting up a vacuum. With a broom, the user sweeps up and handles dirt particles. A vacuum cleaner may require the user to remove bags from the vacuum or repeatedly empty the waste cup. Some cleaning devices have attempted to handle both wet and dry media, but some of these devices may have longer setup times than using a broom followed by a mop. Additionally, the post-use maintenance costs for these devices, especially those involving cleaning liquids, can be higher. For example, some combination tools can become unsanitary or develop odors if not properly cleaned after each use.

[0046] The inventors have recognized the advantages of having a cleaning head that collects moist and / or dry debris and can be removably attached to a cleaning device. A waste collection chamber can be attached to the removable cleaning head to collect waste sucked into the vacuum cleaner. The cleaning head can be configured such that the waste collection chamber is processed together with the cleaning head, rather than being an open waste collection chamber for processing the collected waste.

[0047] For the purposes of this document, the contaminant drawn into the contaminant collection chamber may include dry and / or moist media. For example, in some embodiments, liquid applied to a surface may be absorbed by a cleaning pad and also drawn into the contaminant collection chamber by vacuum. In some embodiments, a moist media may be used to absorb at least a portion of the material forming the contaminant collection chamber. In some embodiments, the contaminant collection chamber may be formed of a material that allows fluid to be absorbed into the material but does not allow fluid to be transported through the material. In such embodiments, fluid may not pass through the contaminant collection chamber. For example, the material used to form the contaminant collection chamber may be absorbent on the inside of the contaminant collection chamber but impermeable.

[0048] In some embodiments, the waste collection chamber may be permanently attached to the cleaning head. In some embodiments, without requiring disassembly of components, the waste collection chamber may be arranged to provide air filtration over a considerable surface area of ​​the waste collection chamber wall.

[0049] Advantages can also be gained if users do not have to handle a wet or dirty cleaning head after operating the cleaning device. For example, the cleaning device can be arranged to release the cleaning head after use, so that the user does not have to grasp the cleaning head to discard it. By using a permanently attached waste collection chamber and a release device that does not require user contact with the cleaning head, the cleaning head can be handled with limited or no user contact.

[0050] In some embodiments, the cleaning head includes a support structure to which the waste collection chamber is attached. In such embodiments, the user can simply attach the cleaning head to the cleaning device, operate the cleaning device to move waste from the surface into the waste collection chamber, remove the cleaning head, and place the cleaning head into the waste container. This process can be repeated each time the user cleans the surface.

[0051] In some embodiments, the cleaning device may include a cleaning blade and / or a liquid spray assembly to aid in cleaning. In such embodiments, because the cleaning head may be the only part of the cleaning device used to contact the surface and contain wet and / or dry debris, the rest of the cleaning device can remain clean throughout and after the entire operation of the cleaning device.

[0052] As will be understood, the underside of the cleaning head can directly contact the surface to be cleaned. In other embodiments, the underside can indirectly contact the surface to be cleaned. For example, the underside of the cleaning head may have one or more wheels to facilitate movement of the cleaning head on the surface. As another example of the underside of the cleaning head indirectly contacting the surface, the cleaning head may include a cleaning pad that contacts the surface to clean it during operation of the cleaning device. In some embodiments, the cleaning head includes a support arranged to hold the cleaning pad on the cleaning head. In such embodiments, the cleaning pad may be permanently or removably attached to the cleaning head.

[0053] In some embodiments, the cleaning head includes a suction port to move debris from the surface into a dirt collection chamber. In some embodiments, the suction port includes a nozzle, which extends across the front of the cleaning head in some embodiments. In some embodiments, the nozzle may be permanently attached to the cleaning head. For example, the nozzle may be integrally formed with a support structure of the cleaning head. In other embodiments, the nozzle may also be removably attached to the cleaning head. In some embodiments, the nozzle is fluidly connected to a vacuum source of the cleaning head.

[0054] In some embodiments, the waste collection chamber is located on the upper side of the cleaning head. In some embodiments, the waste collection chamber protrudes from the upper side of the cleaning head.

[0055] In some embodiments, the cleaning device includes a body having a handle, a vacuum device, a source, and a connector for connecting a cleaning head to the cleaning body. In some embodiments, the connector includes a first engagement element, and the cleaning head includes a second engagement element arranged to engage with the first engagement element to connect the cleaning head to the body of the cleaning device. In such embodiments, once the first engagement element and the second engagement element are engaged with each other, the cleaning head is held to the connector.

[0056] In some embodiments, at least a portion of the waste collection chamber may be covered by the cleaning device when the cleaning head is attached to it. For example, in some embodiments, the waste collection chamber may be used to cover the connector for connecting the cleaning head to the cleaning device. In some embodiments, the waste collection chamber may be at least partially formed by an air filter. In such embodiments, the air filter portion is covered by the connector when the cleaning head is attached to the cleaning device, and suction is applied to the air filter.

[0057] In some embodiments, the body includes a nozzle and a liquid reservoir for supplying liquid to the nozzle. As will be understood, the liquid reservoir may be removably or permanently attached to the cleaning device.

[0058] In some embodiments, the cleaning head is arranged to be disposable. For example, the cleaning head may include a support made of thermoformed plastic or cardboard pulp. In some embodiments, the cleaning head is stackable. In some embodiments, the waste collection chamber is configured to be foldable. For example, the waste collection container may include a bag.

[0059] Figure 1 A cleaning device 100 according to an embodiment of the present disclosure is shown. As illustrated in the figure, the cleaning device 100 may include a body 102 having a handle 104, a connector 106, and a cleaning head 108, the cleaning head 108 being removably attached to the body, for example, via the connector. In some embodiments, the handle may have an adjustable length to allow a user to adjust the height of the cleaning device. For example, the handle may be telescopic to increase or decrease its length.

[0060] like Figures 2 to 4 As shown, the cleaning head 108 may include a dirt collection chamber 112 to collect debris removed from the surface. As will be understood, the dirt collection chamber may be a dirt cup, dirt bin, or any other suitable container for collecting dirt such as dust or damp and / or dry media. In some embodiments, the cleaning head may have a support structure 110. In such embodiments, the dirt collection chamber 112 may be permanently attached to the support structure. For example, the dirt collection chamber 112 may be glued, heat-sealed, or otherwise permanently attached to the support structure. In some embodiments, such as Figure 4 As shown, the support structure is a generally flat support frame, but the support structure may also have other suitable arrangements. In the illustrated embodiment, the support structure is arranged to contact the surface to be cleaned. In some embodiments, the support frame may directly contact the surface to be cleaned, but in other embodiments, the support frame may indirectly contact the surface to be cleaned (e.g., via one or more wheels, cleaning pads, or padded cleaning pads).

[0061] In some embodiments, the waste collection chamber 112 projects upward from the support structure 110. For purposes herein, the term "projecting upward" means that the waste collection chamber projects away from the support structure in a direction away from the surface being cleaned. In some embodiments, the support frame includes one or more recesses 115 to increase the rigidity of the support frame.

[0062] As will be understood, the support structure and the waste collection chamber do not need to have the same shape or size. For example, in some embodiments, the support structure may be larger than the waste collection chamber. In some embodiments, the support structure may be generally rectangular (top view), while the waste collection chamber may be generally elliptical, racetrack-shaped, or other curved (top view).

[0063] In some implementations, such as Figures 2 to 6 As shown, the cleaning head may include a cleaning plate 114. The cleaning plate may be attached to the lower surface of the cleaning head. The lower surface of the support structure may be positioned opposite to the surface to which the waste collection chamber is attached. In some embodiments, the cleaning plate may be larger than the support structure, but in other embodiments, the cleaning plate may be the same size as the support structure or smaller than the support structure. The support structure and the cleaning plate may be of the same shape or they may have different shapes.

[0064] In some embodiments, the cleaning pad can be permanently attached to the cleaning head, such as permanently attached to a support structure. For example, the cleaning pad can be glued, heat-sealed, or otherwise securely attached to the support structure. In some embodiments, such as Figure 12 As shown, the cleaning plate 314 can form a support structure for the cleaning head 308. In such an embodiment, the waste collection chamber 312 can be directly attached to the upper surface of the cleaning plate 314.

[0065] In some embodiments, the cleaning disc can be removably attached to the cleaning head. For example, the support structure may have one or more hook and loop fasteners that engage with hook and loop fasteners on the cleaning disc. In another embodiment, such as Figures 9 to 10 As shown, the cleaning pad 214 may include a recess into which the support structure 210 is slidably inserted. As will be understood, in such an embodiment, the cleaning pad can be attached to the cleaning head before it is attached to the cleaning device, such as to the support structure and / or the waste collection bin. The cleaning pad can also be attached to the cleaning head after it is attached to the cleaning device.

[0066] In some implementations, such as Figures 3 to 4As shown, the cleaning head may include an airflow duct 116 arranged to transfer debris into a waste collection chamber 112. As will be understood, the airflow duct may include a pipe, passageway, channel, or simply an opening leading to the waste collection chamber. In some embodiments, such an opening in the waste collection chamber is always open. In other embodiments, such an opening may be selectively opened and closed. For example, as will be described, the cleaning head may include a valve that is selectively open to allow debris into the waste collection chamber and selectively closed to prevent debris from escaping from the waste collection chamber.

[0067] In some embodiments, the cleaning head includes a suction port arranged, for example, via an airflow duct, to transfer debris from the surface into a dirt collection chamber. In some embodiments, the suction port includes a nozzle 118. In some embodiments, such as Figure 2 As shown, for example, the nozzle may extend laterally along the front portion of the cleaning head. The nozzle can have any suitable shape and size. In some embodiments, the nozzle may extend along the entire width of the cleaning head.

[0068] In some embodiments, the suction nozzle 118 may be attached to the support structure 112. For example, the suction nozzle may be glued, heat-sealed, or otherwise permanently attached to the support structure. In some embodiments, such as Figure 2 as well as Figures 9 to 10 In the embodiment shown, the suction nozzle can be attached by being integrally formed with the support structure. For example... Figure 12 As shown, in some embodiments, nozzle 318 may be attached to cleaning disc 314. The nozzle may also be removably attached to a support structure or to another suitable portion of the cleaning head.

[0069] In some implementation methods, such as Figures 3 to 4 In the embodiments shown, the cleaning pad can be arranged such that the support structure is raised away from the surface to be cleaned, so that the nozzle does not contact the surface. In some embodiments, the nozzle can be positioned between 5 mm and 8 mm from the surface. In some embodiments, the nozzle can be positioned at a distance of 5.5 mm ± 0.5 mm from the surface. Figures 5 to 6 As shown, the cleaning pad can be positioned behind the nozzle so that debris can be collected in the nozzle before the cleaning pad reaches the debris.

[0070] In some implementations, such as Figure 13 As shown, the cleaning head may include a sealing surface 340 configured to form a seal between the cleaning head and the surface being cleaned. In some embodiments, the sealing surface 340 may include recycled cardboard pulp material attached to the cleaning head (e.g., a support structure). The seal may also be formed from a rubber scraper.

[0071] In some implementations, the nozzle can be sized to allow both large and small particles to be drawn into the waste collection chamber while still maintaining a high air velocity for easy pickup. Large particles can be collected through the central portion of the nozzle, which has a large central opening, while small particles can be collected along the entire length of the nozzle.

[0072] In some embodiments, the waste collection chamber can be arranged to retain waste within it once it has been moved into the chamber. In some embodiments, the waste collection chamber includes a lip and an internal valve that, once waste has been moved into the chamber, retains dust, drying media, and / or moist media within the waste collection chamber, thereby preventing dust and drying media from being discharged via the suction port, for example, when the vacuum is closed. In some embodiments, such as... Figure 4 and Figure 6 As shown, the waste collection chamber may include a valve 119 located at or near the airflow duct that can be selectively opened and closed. In some embodiments, the valve may include one or more discs 120a, 120b, which are capable of being in the open position O when a vacuum is applied (see Figure 1). Figure 17 ) and the closed position C when the cleaning device is turned off (see Figure 17 It pivots between ).

[0073] As will be understood, in some embodiments, the valve may be integrally formed with at least a portion of the cleaning head. For example, the valve may be integrally formed with a support structure. The valve may also be formed separately and attached to the cleaning head. For example, the valve may be fixedly attached to the waste collection chamber.

[0074] like Figure 14 As shown, in some embodiments, connector 106 is pivotally connected to the body 102 of the cleaning device to allow cleaning head 108 to pivot relative to the body (see arrow P). As will be understood, the connector may pivot about one or more axes of rotation as it moves relative to the body of the cleaning device.

[0075] In some embodiments, when the cleaning head is connected to the connector, at least a portion of the dirt collection chamber 112 of the cleaning head is covered by the connector. In some embodiments, the entire dirt collection chamber is covered by the connector. The connector may also cover a portion of the support structure. In some embodiments, the connector does not cover the nozzle, but in other embodiments, the connector may be arranged to cover at least a portion or the entire nozzle.

[0076] In some embodiments, at least a portion of the waste collection chamber may be formed of a filter material. As will be understood, this filter material can filter debris and moisture, causing debris and moisture to remain in the waste collection chamber as air flows toward the suction source. Figure 15 and Figure 16 As shown, for example, dirty air, debris, and / or moisture can remain in the dirt collection chamber 112 as clean air flows toward the suction source (see arrow A). In such an example, the airflow passes through a portion 113 of the dirt collection chamber formed by filter material. In some embodiments, such as Figure 2 As shown, the waste collection chamber may include a top 113a and one or more side portions 113b. In some embodiments, at least one of the side portions 113b is made of filter material. In some embodiments, the entire waste collection chamber is made of filter material.

[0077] In some embodiments, the cleaning device may have an additional filter to remove particles that escape through the filter in the dirt collection chamber. In some embodiments, the filter may be located on connector 106.

[0078] As will be understood, although the cleaning head has been shown and described as having a suction nozzle for moving debris from a surface into a dirt collection container, in some embodiments, the suction nozzle or at least a portion thereof may be located on the connector. For example, as Figures 7 to 8 As shown, the cleaning head may have only a portion 417a of the nozzle, and the connector may have the other portion 417b of the nozzle (see Figure 1). Figures 18 to 19 In some embodiments, connector 406 may cover at least a portion 417a of the suction nozzle located on the cleaning head. In some embodiments, the cleaning head and connector remove debris from the floor to a waste collection chamber. In yet another embodiment, the cleaning head may not include a nozzle. In such an embodiment, the connector may include a suction nozzle.

[0079] According to another aspect of this disclosure, the cleaning head can be removably attached to the cleaning device. In some embodiments, the connector includes an engagement element that engages with a corresponding engagement element to hold the cleaning head to the cleaning device during operation. As will be understood, the handle may include an actuator 161 to selectively engage the engagement element on the cleaning device or disengage the engagement element on the cleaning device.

[0080] In some implementations, such as Figure 14 As shown, the engagement element includes jaws 150a, 150b capable of selectively pivoting between an engagement position (e.g., facing each other) and a release position (e.g., away from each other). In some embodiments, each jaw is capable of moving independently between the release position and the engagement position. In other embodiments, the first jaw and the second jaw move simultaneously between the engagement position and the release position. As will be understood, the jaws may be biased toward the engagement position such that when the user releases the actuator, the jaws engage with a corresponding recess 152 on the engagement element 151 of the cleaning head 108 (see [link to documentation]). Figure 2 ).

[0081] In some embodiments, the jaws are movable between a closed position and an engaged position via an engagement element on the cleaning head. For example, the engagement element 151 may have a tapered contact surface 153 that contacts the jaws and moves the jaws away from each other until the jaws move into the corresponding recess 152, at which point the jaws can move toward each other into the engaged position.

[0082] In other implementations, such as Figures 20 to 22 As shown, the cleaning head may be an opening 154 into which a pair of claws 156 can be inserted. Therefore, the user can then twist the actuator 158 attached to the claws to lock the cleaning head to the connector. In such an embodiment, the claws may be spring-biased.

[0083] In some embodiments, the cleaning head is made of a rigid material, allowing it to maintain its shape and the nozzle to retain its shape when held to the connector. For example, the cleaning head may be made of cardboard or thermoformed plastic material. In some embodiments, the support structure includes grooves to increase the rigidity of the support structure.

[0084] In some embodiments, the cleaning apparatus includes a vacuum source arranged to apply a vacuum to move dirt from the floor to be cleaned into a dirt collection chamber. For example... Figure 4 , Figure 11 as well as Figures 15 to 16 As shown, the vacuum source provides suction, drawing air and any loose debris through the nozzle and airflow duct into the waste collection chamber. In this configuration, the nozzle is fluidly connected to the airflow duct and the waste collection chamber. In some embodiments, the vacuum source can be controlled via an actuator 149 located on the handle (see [link to manual description]). Figure 1 ).

[0085] In some embodiments, the vacuum source may be located inside the body of the cleaning device. For example, the vacuum source may be located near or within the liquid reservoir 159. In some embodiments, the vacuum device may remain attached to the handle when the liquid reservoir is removed. In some embodiments, the vacuum source may be removed together with the liquid reservoir. The vacuum source may also be located near the connector and the removable cleaning head. In some embodiments, the vacuum device may include a motor. The vacuum source may include a secondary filter.

[0086] In some embodiments, a vacuum source applies a vacuum to the entire exposed portion of the waste collection chamber, such as the walls of the waste collection chamber formed of air filter material. This arrangement can provide sufficient airflow without creating excessive pressure drop across the air filter. In some embodiments, the waste collection chamber protrudes upward from the cleaning head to allow the connector to apply a vacuum to the waste collection chamber material. In such embodiments, this arrangement allows the bag to be filled towards its periphery and then towards its center.

[0087] In some implementations, such as Figure 28 As shown, the lower portion of the connector includes one or more posts 160 for separating the waste collection chamber from the vacuum source. In some embodiments, the connector may have 30 to 40 posts, but any suitable number of posts can be used. This separation allows a vacuum to be applied to the entire exterior and surrounding area of ​​the exposed portion of the waste collection chamber.

[0088] In some embodiments, the cleaning device may include a nozzle 155 arranged to apply liquid to the surface to be cleaned. In some embodiments, the nozzle may be located on the body of the cleaning device. The nozzle may also be located on a connector. It will be understood that the nozzle may be located at any suitable position for applying liquid to the surface to be cleaned.

[0089] In some embodiments, the device may include a liquid reservoir 159 arranged to supply liquid to the nozzle. In some embodiments, the reservoir may be permanently attached to the cleaning device, for example, permanently attached to the body. The reservoir may also be removably attached to the cleaning device. In some embodiments, a user may add cleaning fluid and / or water to the liquid reservoir, for example, through a filling port on the reservoir. In some embodiments, the liquid reservoir may be sized to include a volume of liquid for several cleaning events. In this embodiment, the user only needs to attach the cleaning head before operating the cleaning device. In some embodiments, the liquid reservoir may be pre-filled, allowing the user to purchase one or more liquid reservoirs and attach one or more liquid reservoirs to the cleaning device when the liquid reservoirs are empty.

[0090] In some implementations, the handle includes an actuator 157 to allow a user to activate the nozzle to apply liquid to the surface to be cleaned.

[0091] In some embodiments, the cleaning device may be battery-powered. In this embodiment, the battery may be rechargeable. In this embodiment, the user can charge the battery between uses. In some embodiments, the battery is configured to maintain power for one, two, three, or more cleaning events. In some embodiments, the battery is replaceable. In some embodiments, the cleaning device may be powered by a cord plugged into a power outlet.

[0092] According to another embodiment, such as Figures 23 to 26 As shown, a method for using a cleaning device is disclosed. Figure 23 As shown, the user can select the first cleaning head from a box of disposable cleaning heads. Next, the user attaches the first cleaning head to the cleaning device. Figure 24 In this embodiment, attaching the first cleaning head includes a connector for attaching the cleaning head to the cleaning device. In some embodiments, the cleaning head includes a dirt collection container permanently attached to the cleaning head. The cleaning head may also include a cleaning pad and a suction nozzle attached to the cleaning head. The method includes operating the cleaning device to move dirt through the suction nozzle and into the dirt collection chamber. In some embodiments, a user may apply liquid to the surface to be cleaned (see...). Figure 25 The method also includes removing the cleaning head from the connector and placing the cleaning head in the waste container. Figure 26 ).

[0093] In embodiments where the cleaning pad is attached to the cleaning head, wet and dry debris can be cleaned separately or simultaneously. For example, in some embodiments, a vacuum source can be turned on, allowing debris to move from the surface into the dirt collection container. Dry debris already on the floor can be picked up by the cleaning pad simultaneously with the vacuum source being turned on. In some embodiments, the surface may also include wet spills, which can be absorbed by the cleaning pad simultaneously with the vacuum source being turned on. As will be understood, in some embodiments, the cleaning device may function solely as a vacuum cleaner. In some embodiments, when the vacuum source is turned on, the user can operate the nozzle (e.g., by pressing an actuator) to apply liquid to the surface to be cleaned. In this embodiment, the cleaning device can operate simultaneously as a vacuum cleaner and a mop. In some embodiments, the user can spray liquid onto the surface in the path of the cleaning head, allowing wet debris to be absorbed into the cleaning pad as the vacuum cleaner moves debris from the surface into the dirt collection chamber. In some embodiments, the liquid can be sprayed onto the floor in a fan-shaped pattern, but the liquid can be sprayed onto the floor in other suitable patterns.

[0094] It will be understood that the cleaning device can also operate solely as a mop. In this case, the user can simply (e.g., by pressing the actuator) operate the nozzle to apply liquid to the surface to be cleaned. In this embodiment, the user can move the cleaning device back and forth to clean the floor. In embodiments where the cleaning pad is removably attached to the cleaning head, the user can remove and discard the cleaning pad. In embodiments where the cleaning pad is permanently attached to the cleaning head, the user can discard the cleaning head after using the cleaning device as a mop.

[0095] In some embodiments, processing the cleaning head includes discarding the cleaning head, in which dirt and debris are contained in a dirt collection container and / or absorbed in the cleaning pad. In some embodiments, processing the cleaning head includes activating a release mechanism. For example, the release mechanism may move a first and second jaw member away from each other to release the fastener from between the jaws and allow the cleaning head to disengage from the connector. As will be understood, in this embodiment, since the user only activates the release mechanism, the user may not be able to handle a wet or dirty cleaning head. As will be further understood, since the cleaning head is the only part of the cleaning head contact surface, and all wet and / or dry debris is contained within the cleaning head, the rest of the cleaning device (e.g., the connector and body) can be cleaned throughout and after the operation of the cleaning device.

[0096] For the purposes of this article, containing debris in the waste collection chamber means that the user cannot open the waste collection chamber to dispose of the debris collected therein. Instead, as described above, the cleaning head with the trapped debris is discarded into the trash container. It will be understood that the user may tear or cut open the waste collection chamber to allow the debris to be emptied into the trash container; however, such an action may damage the waste collection chamber and may prevent the user from continuing to use the cleaning head. In a similar manner, the user may also break or pry open the dust collector. As in the previous example, this action may also damage the cleaning head, making it potentially unusable with the cleaning device.

[0097] In some implementations, such as Figure 27 As shown, the cleaning heads can be stacked on top of each other. In some embodiments, the cleaning heads can be nested as a stack. In this embodiment, the nozzle of the first cleaning head can be nested within the nozzle of the second cleaning head. In some embodiments, the waste collection chamber is foldable to allow the first cleaning head to be stacked on top of the second cleaning head. In this embodiment, the first waste collection chamber of the first cleaning head can be folded under the support structure of the second cleaning head. The first collection chamber can also be folded under the cleaning plate attached to the second cleaning plate.
