The present disclosure is related to cleaning devices. More particularly, the present disclosure is related to cleaning devices that spray cleaning fluids to assist the cleaning of hard surfaces.
Cleaning devices that allow for the cleaning of hard surfaces such as, but not limited to, window, walls, counters, floors, mirrors, tiles, tables, and others are known. Some prior art cleaning devices are also known to include cleaning fluid spraying systems—that allow the user to spray cleaning fluid onto the surface to be cleaned.
However, it has been determined by the present disclosure that such prior art cleaning devices are less than optimal.
Accordingly, there is a need for improved hard surface cleaning devices that improve upon, overcome, alleviate, and/or mitigate the deleterious effects and inefficiencies of prior art devices

The dispensing section 30 includes the housing 36. As will be discussed in more detail herein, the housing 36 contains a cleaning fluid storage and dispensing assembly. In an embodiment, the cleaning fluid storage and dispensing assembly is operably coupled to the actuator 26 and any other actuators on the device 20 for causing the cleaning fluid storage and dispensing assembly to dispense cleaning fluid during operation. The dispensing section 30 is connected to a cleaning head 38 by a connector 40. The connector 40 may be any suitable hinged attachment that allows the head 38 to rotate about a single or two orthogonal axis during operation. A cleaning element 42 couples to the head 38. The element 42 may connect with the head 38 via straps 44, or by other suitable means, such as a hook and loop fastener for example. The cleaning element 42 may be a cleaning pad made from a suitable material, such as but not limited to microfiber, cotton, wool, non-woven fibers, or any combination thereof. The cleaning element 42 may further include other elements, such as but not limited to brush bristles, a squeegee, a scraper, or any other cleaning element or combinations thereof. In an embodiment, an adapter plate 41 (
The dispensing section 30 is further fluidly coupled to the head 38 by a conduit or dispensing tube 46 that exits an outlet 48 below removable cover 50 in the housing 36. As will be discussed in more detail herein, the tube 46 couples with a pump and provides a fluid pathway for transferring cleaning fluid to the head 38. The tube 46 connects with a spray nozzle 54 via an inlet 52. In the illustrated embodiment, the head 38 and the cleaning element 42 each include a central opening 56, 58 respectively. The nozzle 54 is recessed with respect to the bottom surface of the head 38, which offsets the nozzle from the cleaning surface to facility distribution of the cleaning fluid and prevent the nozzles from being damaged during use.
Without wishing to be bound by any particular theory, it is believed that device 10—by capturing the spray of the cleaning fluid between head 38 and the surface being cleaned—prevents airborne cleaning fluid from being present in the air near the user's mouth and nose, particularly as the device is held at or above head level while cleaning windows, mirrors, and the like. In the example where device 20 is used in window cleaning, the cleaning fluid often includes chemicals with a viscosity low enough to be formed into a mist—namely atomized or formed into an aerosol—by the spraying through nozzles 54. When prior art window cleaning devices are used to clean items at or above the user's mouth and nose, the atomized cleaning fluid can disadvantageously pass through the breathing space—an outcome that device 20 reduces by constraining the spray of the cleaning fluid between head 38 and the surface being cleaned.
As discussed herein, the device 20 is configured to pump cleaning fluid from container 60 to one or more spray nozzles 54 (one shown) directly onto the surface being cleaned. Here, central opening 56 that is in alignment or registration with an opening 58 in the cleaning member 42, 42A (and the adapter plate 41 in some embodiments) so that spray nozzles 54 spray the cleaning fluid through the openings onto the surface being cleaned. Without wishing to be bound by any particular theory, head 38 defines a chamber around nozzles 54 and positions the nozzles 54 a predefined distance from the surface being cleaned. In an embodiment, device 20 is configured to capture any spray of the cleaning fluid within head 38 and is particularly configured to ensure coverage of the surface being cleaned by allowing the spray from the nozzles 54 to have sufficient space, volume, or time to form larger droplets until all the chemical is on the surface being clean.
It has been determined by the present disclosure that, in some embodiments, there is a relationship between the height of nozzle 54 from the surface being cleaned (measured to the surface of the pad) and the volume of the chamber, examples of which are illustrated in Table 1.

The opposite end 76 of the container 64 includes a output cap 78 having an opening 80 (
The container 64 includes a valve assembly 92 as shown in
Coupled to the valve housing 96 is a directional flow valve 104. The flow valve 104 includes a conduit 106 that is sized to be received in the end of the valve housing 96. The conduit 106 fluidly couples the valve housing 96 to a directional chamber 108 (
Fluidly coupled to the ball valve chamber 112 is an input tube member 124. The input tube member 124 includes an input chamber 126 that is selectively fluidly coupled to the ball valve chamber 112 via a passageway 128. In an embodiment, the passageway 128 is fluidly coupled to a pair of inlets 130 (
Coupled to the input tube member 124 is a second take-up tube 132 via a second tube adapter 133. Coupled to an opposite end of the second take-up tube 132 is a second filter 134. It should be appreciated that when the valve assembly 92 is in the second position as shown in
It should be appreciated that when the storage container 64 is in the orientation similar to
In one embodiment, shown in
When the valve assembly 92 is disposed within the interior 136 (
In other embodiments container 64 can be permanently connected via a tube (tether) such that no pivot arm 82 is provided. In this embodiment, the tube 70 connects directly to the output cap 78 and is sized long enough so that the end user can remove the container from the housing to fill the bottle.
In operation, the user first fills the container 64 with the desired cleaning fluid. It should be appreciated that the container 64 may be filled with the cleaning fluid and coupled to the pivot arm 82, or external to the device 20. Once the cap 74 is placed on, the user installs the container 64 (if filled externally) by sliding the pivot arm 82 into the opening 80 in output cap 78. The seal 90 engages the inner surface of the opening 80 to both seal and secure the output cap 78 to the pivot arm 82. It should be appreciated that the coupling of the container 64 to the pivot arm 82 may be performed with the pivot arm 82 rotated relative to a longitudinal axis of the housing 36 or with the pivot arm 82 in the operating position. Once the container 64 is installed, the pivot arm 82 can be rotated to the operating position (
When the user positions the device 20 with the cleaning element 46 vertically below pole 22, such as when cleaning a floor or the bottom of a pane of glass from a standing position for example, the valve assembly 92 is oriented with the second filter 134 being vertically lower than the first filter 122. It should be appreciated that when in this position, the spherical member 114 is positioned with the inlets 130 in an “open” configuration to allow a fluid path from the second filter 134 to the disk valve 102. It should further be appreciated that any cleaning fluid in the container 64 will flow towards the end 76 under the influence of gravity. Thus, unless the storage container 64 is substantially filled with cleaning fluid, the first filter 122 will not be in fluid communication with the cleaning fluid, while the second filter 134 will be in fluid communication with the cleaning fluid. As such, when the pump 66 is operated, the cleaning fluid will flow from the interior 136 through the second filter 134, along the second fluid pathway through the disk valve 102 and into the pump, where it is subsequently flowed to the nozzles 54 via the dispensing tube 46.
Conversely, when the device 20 is reoriented such that the end 76 is vertically higher than the cap 74, the second filter 134 may no longer be in fluid communication with the cleaning fluid since the cleaning fluid will flow to the end of the storage container 64 adjacent the cap 74. It should be appreciated that this orientation may occur when the user is cleaning a higher section of a wall or window, or the ceiling for example. When in this position, the first filter 122 will be in fluid communication with the cleaning solution. Further, when the end 76 is vertically higher than the cap 74, the spherical member 114 will move against the inlet 110 to seal the directional chamber 108 from the ball valve chamber 112. As a result, when the pump 66 is activated, instead of pulling air from the end 76 of the storage container 64, the cleaning fluid will flow into the first filter 122 and along the first fluid pathway to the disk valve 102 and into the pump, where it is subsequently flowed to the nozzles 54 via the dispensing tube 46.
It should be appreciated that the valve assembly 92 provides advantages in allowing the device 20 to be operated in a variety or orientations while still allowing the flow of cleaning fluid from the storage container and the user can use chemical of their choosing.
