DETAILED DESCRIPTION OF THE INVENTION

While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred, albeit not limiting, embodiment with the understanding that the present disclosure is to be considered an exemplification of the present invention, and is not intended to limit the invention to the specific embodiments illustrated.


Referring to FIG. 1, an illustrative example of an electric shaver configured to dispense one or more fluids, referred to generally as a fluid dispensing electric shaver 10, is shown. The fluid dispensing electric shaver 10 comprises two main components, a fluid dispensing unit 12 and a shaving unit 14. The fluid dispensing unit 12 is configured to receive and hold one or more liquids, and contains a first pair of opposing side walls 15 and 16, and a second pair of opposing side walls 18 and 20. Walls 15, 16, 18 and 20 surround a bottom wall 22, thereby partially enclosing an interior region 24. A top wall 26 fully encloses the interior region 24. Preferably, the top wall 26 is removably secured to or attachable to the walls 15, 16, 18, and 20 so that one or more fluids can be placed within or taken from the interior region 24. The shaving unit 14 is configured to cut body hair and dispense one or more fluids, and comprises a main body 28 housing, one or more electrical components that drive functionality, i.e. cutting hair, a razor blade head 30, having one or more razor blades 32 to cut body hair, and a power on/off button 34, allowing a user the capability to power on or power off the shaving unit 14.


The fluid dispensing electric shaver 10, in accordance with the present invention, is designed to provide a close shaving unit that can be used to clean a user's face. The advantage of the device is that it provides both body hair cutting while providing the mechanism to dispense cleaning solutions in order to prevent oil and dirt build up, minimize ingrown hair, razor burn, or the development of acne and pimples, as a result of shaving. As such, the fluid dispensing electric shaver 10 is configured to both cut body hair and dispense fluids.



FIG. 2 provides a schematic diagram illustrating the various functional components of the shaving unit 14. As shown illustrated, the fluid dispensing unit 12 is composed with two separate fluid holding sections, a first water tank 36 configured to receive and hold water, and a separate second tank configured to hold a liquid solution that can be used to clean or hydrate a user's face. As such, the separate second tank 38 may hold soap solution, antibacterial solution, or hydrating skin liquid. Hydrating skin liquid is designed to increase the water content of the skin, and may contain one or more ingredients, extracts, antioxidants and moisture-binding ingredients to leave skin soft and hydrated. Hydrating skin liquid generally works by utilizing the powers of various hygroscopic ingredients, like humectants. A hygroscopic substance has the ability to attract water from its surroundings through absorption or adsorption, such as glycerin, honey and hyaluronic acid. As humectants, these substances absorb water from the air and bind it to the skin, facilitating hydration.


To provide the liquids, either the water stored in the first water tank 36 or the soap/antibacterial/hydrating liquid stored in the second tank 38, with thermal regulation, the user may add previously cooled or heated water to the fluid dispensing unit 12. The first tank 36 or the second tank 38 may be designed to be removable so that a user can take the tank to a water source, such as a sink and fill them up. The fluid dispensing unit 12 contains a control unit, such as a microprocessor 44. The microprocessor 44 may be a single integrated circuit (IC) or a few integrated circuits. A tactile device, such as a knob or dial 46, allows a user to control and manipulate the various functions associated with the fluid dispensing electric shaver 10. FIG. 3 illustrates an example of the knob or dial 46 integrated into the side wall 16. The user can easily change settings by rotation of the knob or dial 46.


The liquid(s) stored within the fluid dispensing unit 12 are transferred to the shaving unit 14 through cord 54, see FIGS. 1 and 2. The cord 54 may be retractable, or may contain extendable coils 56. The cord 54 is designed to have a first end 58 that connects to the fluid dispensing unit 12 and a second end 60 that connects to the shaving unit 14. The first end 58 may be connected to the first water tank 36 by a water tank connection portion 62. The water tank connection portion 62 draws water stored within the first water tank 36 out towards the shaving unit 14. The first end 58 may also be separately connected to the second tank 38 by connection to a second tank connection portion 64. The second tank connection portion 64 draws fluid, i.e. soap, stored within the second water tank 38 out toward the shaving unit 14. The fluid drawn from the first tank 36 and the fluid drawn from the second tank 38 mix together at a common junction point 66 and travel to the shaving unit 14 as a mixed fluid (water in combination with soap/antibacterial/hydrating liquid).


The mixed fluid is transferred into the main body 28 of the shaving unit 14 via a fluid transfer tube 68. The shaving unit fluid transfer tube 68 runs along the length of the main body 28 and branches off, forming one or more independent tubes 70, terminating at the razor head 30 or independent tubes 72 at, near or within the blades 32. The independent tubes 70 or 72 terminate in an opening 74A (within razor head) or 74B (within razor blade) sized and shaped to disperse the mixed fluid, see also FIG. 4. The main body 28 of the shaving unit 14 may contain a button layout 75 configured to change settings of the razor blade 32 to control speed or cutting length. The main body 28 of the shaving unit 14 may also contain green display lights 76 or red display lights 78 to indicate power on (green) or power off (red). Finally, fluid control button 77 may be operatively coupled to a fluid flowing control member, such as a valve 79, to control fluid flow. The fluid control button 77 may be configured to allow fluid to flow once a user presses the fluid control button 77, opening valve 79. Alternatively, the valve 79 may be placed in a continually open position to allow fluid to flow once the shaving unit 14 is operating, i.e. turned on. In this case, pressing the fluid control button 77 closes the valve 79, thereby preventing fluid flow.


The fluids, either the water or soap, exiting the first water tank 36 or the second tank 38, may be controlled by a pump 80. The control unit 44 may be programmable to control the amount, form dispersed (spray or mist), and/or the pressure of any fluid transferred from the fluid dispensing unit 12 to the shaving unit 14. The fluid dispensing unit 12 may be plugged into a source of power using an electrical plug 82.


Referring to FIGS. 5-10, an alternative embodiment of the fluid dispensing electric shaver illustrated with removable components, referred to generally as fluid dispensing electric shaver 100, is shown. While not described in particular, any function, feature, element, or component described for the fluid dispensing electric shaver 10 may be applicable to the fluid dispensing electric shaver 100.

The fluid dispensing unit 112 is configured to receive and hold one or more liquids and contains a first pair of opposing side walls 115 and 116, and a second pair of opposing side walls 118 and 120. Walls 115, 116, 118, and 120 surround a bottom wall 122, thereby partially enclosing an interior region 124. A top wall 126 fully encloses the interior region 124. The top wall 126, walls 115, 116, 118, and 120, or bottom wall 122 may be removable in order to access the interior region 124.


The shaving unit 114 is configured to cut body hair and dispense one or more fluids. The shaving unit comprises a fluid dispensing and cutting assembly unit 128 housing one or more components that drive functionality, i.e. cutting hair or dispensing fluids.


The fluid dispensing electric shaver 100, in accordance with the present invention, is designed to provide a close shaving unit that can be used to clean a user's face. The advantage of the device is that it provides both body hair cutting while providing a mechanism for dispensing cleaning solutions in order to prevent oil and dirt build up, razor burn, or the development of acne and pimples, and minimizes ingrown hair as a result of shaving. As such, the fluid dispensing electric shaver 100 is configured to both cut body hair and dispense fluids.


The fluid dispensing unit 112 preferably contains two separate fluid holding compartments, a first tank 136, referred to herein as the water tank 136 and a separate, second tank 138, referred to herein as the cleaning solution tank 138. The water tank 136 is configured to receive and hold a first liquid, such as water. The cleaning solution tank 138 is configured to hold a liquid solution that can be used to clean or hydrate a user's face. While the fluid dispensing electric shaver 100 is shown with two removable compartments, 3 or more compartments may be used, including one compartment that can be used to store or to mix the water and cleaning solution into a third solution.


The separate, second tank 138 preferably holds a soap solution, an antibacterial solution, or a hydrating skin liquid. Hydrating skin liquid is designed to increase the water content of the skin and may contain one or more ingredients, extracts, antioxidants and moisture-binding ingredients to leave skin soft and hydrated. Hydrating skin liquid generally works by utilizing the powers of various hygroscopic ingredients, like humectants. A hygroscopic substance has the ability to attract water from its surroundings through absorption or adsorption, such as glycerin, honey and hyaluronic acid. As humectants, these substances absorb water from the air and bind it to the skin, facilitating hydration. The water tank 136 and the separate, second tank 138, also referred to as a cleaning solution tank 138, are preferably removably attachable from the fluid dispensing unit 112, and are sized and shaped to fit within a compartment receiving area 137A and 136B, which are shown as cut out portions of the side wall 118, that are sized and shaped to maintain the water tank 136 and the cleaning solution tank 138 secured in placed when inserted therein.


The fluid dispensing unit 112 contains an electronics box 144 which may contain a microprocessor. The microprocessor (not shown) may be a single integrated circuit (IC) or a few integrated circuits and designed to control one or more components. A tactile device, such as a knob or dial 146, and rheostat (not shown) allows a user to control and manipulate the various functions associated with the fluid dispensing electric shaver 100, such as control of the speed of a high-pressure micro electric motor pump. As illustrated, the knob or dial 146 is integrated into the top wall 126, but could be located or positioned anywhere within the fluid dispensing electric shaver 100. The user can easily change settings by rotating and/or pressing of the knob or dial 146 to adjust for various levels of dispensing fluid pressure or speed. Alternatively, the fluid dispensing unit 112 may use a digital speed to control the sped of the high-pressure micro electric motor pump.


The liquid(s) stored within the fluid dispensing unit 112 are transferred to the shaving unit 114 through the hose 154, see FIGS. 8 and 10.
