Referring now to FIG. 1, there is shown a perspective view of the scrubber brush, the docking station, and the interchangeable brush heads of the present invention. The present invention comprises a battery operated scrubber brush 10 having an extendable waterproof handle 15 and a plurality of interchangeable brush heads 20, and a battery charging docking station 25. The handle 15 is extendable via an elongated member, as shown in FIG. 3, slidably disposed in an interior volume thereof. The handle 15 is constructed of water resistant material, such as plastic, and is configured to prevent water from breaching its interior volume and thereby damaging its electronic components. The handle 15 includes a proximal end 30 and a distal end 35, wherein the distal end 35 includes a recessed opening 40 and a drive shaft 45 configured to removably receive the interchangeable brush heads 20. The handle 15 includes an ergonomic shape having a round cross-section for comfortable gripping. Further, the distal end 35 of the handle 15 is curved and increases in cross-sectional area towards the recessed opening 40. In these ways, users may grasp the proximal end 30 of the handle 15 and angle the distal end 35 towards various body parts for cleaning with an interchangeable brush head 20 mounted thereon without having to strain their wrist.
The drive shaft 45 is coupled to an electric motor 48 disposed in the scrubber brush that rotates the drive shaft 45 and drives an interchangeable brush head 20 mounted thereon. The proximal end 30 includes a port 50 for receiving an electrical connector (not shown) disposed in the docking station 25 and one or more activation switches 55 for activating the electric motor 48 and driving the drive shaft 45.
The recessed opening 40 includes a base 42 wherein the drive shaft 45 is centrally disposed thereon. The recessed opening 40 is sized to receive either of the plurality of interchangeable brush heads 20 flush therein. Each of the plurality of interchangeable brush heads 20 includes a planar member 60 configured rest flush within the recessed opening 40. In the depicted embodiment, the planar member 60 is circular in shape. However, in alternative embodiments, the planar member 60 may comprise any variety of shapes configured to rest flush within the recessed opening 40. The planar member 60 includes a lower side 65 having a channel 70 thereon sized to receive the drive shaft 45 therein and an upper side 75 having an arrangement of body cleaning materials. For example, in the depicted embodiment, the scrubber brush 10 includes an interchangeable brush head 20 having a sponge 85, an interchangeable brush head 20 having a first arrangement of a plurality of bristles 90, an interchangeable brush head 20 having a second arrangement of a plurality of bristles 95, and an interchangeable brush head 20 having a third arrangement of a plurality of bristles 100. In this way, a user can detachably mount a brush head 20 having a different arrangement of body cleaning materials to the scrubber brush 10 as desired.
The drive shaft 45 protrudes upwardly and perpendicularly relative to the base of the recessed opening 40. The drive shaft 45 is operably coupled to the electric motor 48 of the scrubber brush 10. The electric motor 48 is disposed in the handle 15 and is operably coupled to a power supply 105 of the scrubber brush 10. Once the scrubber brush 10 is activated, the electric motor 48 rotates the drive shaft 45, which in turn rotates the interchangeable brush head mounted 20 thereon. The one or more activation switches 55 are disposed on the proximal end 30 of the handle 15 and adjust the speed at which the electric motor 48 rotates the drive shaft 45. In this way, a user may adjust the speed at which the electric motor 48 rotates the interchangeable heads rotate as desired. In the depicted embodiment, the scrubber brush 10 comprises a pair of activation switches, wherein one activation switch is for activating the scrubber brush 10 and one activation switch is for adjusting the speed of the drive shaft 45. However, in alternative embodiments, the scrubber brush 10 may comprise one activation switch for activating the scrubber brush 10 and controlling the speed of the drive shaft 45 or more than two activation switches for powering the device on and off, adjusting the speed of the drive shaft 45, extending the handle 15.
The power supply 105 of the scrubber device 10 is disposed in the proximal end 30 of the handle 15 and includes both a rechargeable battery and a disposable battery. The rechargeable battery is operably coupled to the port 50 which is disposed on the tip of the proximal end 30. The rechargeable battery is fixedly mounted into the handle 15 while the disposable battery is accessible via a removable portion 110 which includes a threaded engagement. In this way, a user may recharge the rechargeable battery using the docking station 25 or travel without the docking station 25 and power the scrubber device 10 simply by utilizing disposable batteries and replacing them as needed.
Referring now to FIG. 2 there is shown an exploded view of the brush head being mounted onto the drive shaft and the handle being mounted onto the docking station. The docking station 25 is configured to charge the rechargeable battery of the power supply 105. The docking station 25 comprises an upstanding housing 115 having an open upper end 120 providing access to an interior volume thereof. The interior volume of the housing 115 includes a base 125 comprising an electrical connector 130 and a power plug 135 operably coupled to the electrical connector 130. The power plug 135 is configured to connect to an electrical socket of a structure to supply power to the docking station 25. The port 50 of the scrubber brush 10 is configured to plug into the electrical connector 130 to receive power therefrom. When the port 50 is connected to the electrical connector 130 a light source 140 disposed on an exterior of the housing 115 illuminates, thereby indicating that the scrubber brush 10 is charging.
Referring now to FIG. 3, there is shown a perspective view of the handle of the scrubber brush in an extended position. The proximal end 30 and the distal end 35 of the handle 15 include threaded engagements 140 for threadably engaging and disengaging the handle 15 into a closed and extended position to provide access to the elongated member 145. The elongated member 145 is slidably disposed in an interior volume of the proximal end 30 of the handle 15. The elongated member 145 includes a distal end 150 attached to the distal end 35 of the handle 15, such that when the ends 30, 35 are threadably disengaged the elongated member 145 extends with the distal end 35 of the handle 15. In the depicted embodiment, the elongated member 145 is a straight tubular member having a smaller cross sectional area than the handle 15.
When extending the length of the scrubber brush 10 a user threadably disengages the ends 30, 35 and pulls the ends 30, 35 away from each other. The elongated member 145 then slides longitudinally, outwardly from the proximal end 30 of the handle 15, thereby moving the handle 15 into an open position and extending the length of the scrubber brush 10. When shortening the length of the scrubber brush 10 a user slides the elongated member 145 longitudinally, inwardly back towards and into the interior volume of the proximal end 30, thereby moving the handle 15 into a closed position and shortening the length of the scrubber brush 10. When the elongated member 145 is slid back into the proximal end 30, a user then threadably engages the ends 30, 35 via their threaded engagements 140 to fasten the scrubber brush 10 in its closed position.
In another embodiment, the elongated member 145 is slidably disposed in an interior volume of the distal end 35 of the handle 15 and includes a proximal end attached to the proximal end 30 of the handle 15, such that when the ends 30, 35 are threadably disengaged, the elongated member 145 extends with the proximal end 30 of the handle 15. Thus, when moving the handle 15 into an open position and extending the length of the scrubber brush 10, the elongated member 145 slides longitudinally, outwardly from the distal end 30 of the handle 15.
In an alternative embodiment, the scrubber brush 10 includes a handle extension switch 155 operably coupled to a spring-biased actuator 160 that when depressed, ejects the elongated member 145 from the interior volume of the proximal end 30 of the handle 15, thereby sliding the elongated member 145 longitudinally, outwardly from the proximal end 30 and extending the scrubber brush 10 into the open position. The spring-biased actuator 160 is disposed in the proximal end 30 and biased towards the distal end 35 of the handle. When shortening the length of the scrubber brush 10, the elongated member 145 is slid back into the interior volume of the proximal end 30, which compresses the spring biased actuator 160 in position for ejection.
It is therefore submitted that the instant invention has been shown and described in various embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
