Unlike the prior devices in the field, the present invention allows the user to selectively dispense either cool or warm vapor. The liquid reservoir is designed to accept skin care additives in addition to simple water for generating the vapor. The device has at least three operational modes: vapor only, massage head brush oscillation/massage motion only, and both vapor and oscillation/massage. Power for the device is available from a variety of sources, including internal batteries and/or external power supply.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to facial skin care devices and, more specifically, to a Personal Care Vaporizing Device.
2. Description of Related Art
Facial massage devices are plentiful. The most pertinent examples of conventional devices and systems in this field are: Mehl, Sr., et al, U.S. Pat. No. 6,090,085, Walker, U.S. Pat. No. 5,098,414, and Burian, U.S. Pat. No. 4,616,122.
Mehl is a “Skin Moisturizing and Buffing Device.” The Mehl system combines a handheld facial buffer that has an internal steam generator for creating a stream of steam for emission through the “movable skin contacting assembly” (i.e. the facial buffer head). While the Mehl device does provide a handheld steam buffer, it fails to allow the user the option of either cool vapor or heated steam emitted through the buffer head. Furthermore, the amount of vapor available for use is severely limited due to the entire package being of handheld size. A device providing a large volume liquid reservoir that can emit either heated steam or cool vapor would provide a wider set of benefits to the user.
Walker is a “Steam Device for Cosmetic Skin Treatment.” The Walker device does provide a large water reservoir for use in steam emission, but it fails to provide the option of cool vapor.
Finally, the Burian “Electrically Heated Facial Sauna Vapor Generating Apparatus,” like Walker discloses a large-reservoir, steam generating facial massage device. Just as with Walker, Burian fails to suggest the generation of cool vapor (in addition to hot steam) for facial application through the massage head. The ability to deliver hot or cool vapor through the massage head allows the user to continue the facial massage while heating and cooling the massage head and skin. If only the only option is to deliver steam, then the user must either stop the massage or stop the vapor delivery in the event that the face becomes uncomfortably hot.
SUMMARY OF THE INVENTION
In light of the aforementioned problems associated with the prior devices and systems, it is an object of the present invention to provide a Personal Care Vaporizing Device. The device should have a central base unit having a large removable liquid reservoir and a handheld skin massage/exfoliating device. The handheld assembly should emit vapor directly to the skin surface. Unlike the prior devices in the field, the present invention should allow the user to selectively dispense either cool or warm vapor. The liquid reservoir should also be designed to accept skin care additives in addition to simple water for generating the vapor. The device should have at least three operational modes: vapor only, massage head brush oscillation/massage motion only, and both vapor and oscillation/massage. Power for the device should be available from a variety of sources, including internal batteries and/or external power supply.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide a Personal Care Vaporizing Device.
The present invention can best be understood by initial consideration of FIG. 1. FIG. 1 is a perspective view of a preferred embodiment of the massaging vaporizer device 10 of the present invention. The device 10 is an advancement over the prior art in that it not only provides a substantial liquid reservoir for vapor generation, but also gives the user the option of either hot steam or cool vapor application through the massage head.
The device 10 has a base element 12 which provides a support base for the other elements that make up the device 10. An upper housing 14 is attached atop the base element 12. A reservoir tank 16 is removably attached to the upper housing 14.
As can be seen, the shape of the base element 12, upper housing 14 and reservoir tank 16 are not only ergonomically shaped, but also aesthetically pleasing. There is a holster 22 formed in the upper housing 14 that provides for a convenient storage location for the massage head assembly 18. It is noted that the massage head assembly 18 may be powered by internal batteries; in one version the holster 22 may also include a battery charger so that batteries in the massage head assembly 18 are recharged (if necessary) when the head assembly 18 is placed in the holster 22.
A mist hose 20 interconnects the upper housing 14 and the massage head assembly. The mist hose 20 can be removable from the upper housing, or alternatively, may retract into the upper housing.
There are control switches and buttons dispersed on the base element 12 and massage head assembly 18. There are electrical signal conductors interconnecting the massage head assembly and the upper housing 14 and/or base element 12. These wires or other conductors will be coupled with the mist hose 20, and could be located either on the exterior or the interior of the mist hose 20. The switches and buttons on the base element 12 and elsewhere will be described more fully below in connection with successive drawing figures, beginning with FIG. 2.
FIG. 2 is a partially exploded perspective view of the device 10 of FIG. 1. Here, the reservoir tank 16 has been removed from the upper housing 14. The tank 16 is designed to be removable so that the user can leave the device 10 plugged in at its operating location when adding fluid to the reservoir tank 16. When the tank 16 is installed in the tank holster 31 provided for in the upper housing 14, it is held therein by interface with the latch catch 30. At that point, fluid will be dispensed from the tank 16 through the outlet tube 32, and into the device's vapor-generating system.
The massage head assembly 18 comprises a head housing 24. A detachable brush element 26 is shown here; this element 26 can be exchanged with other types of elements, such as a massage head element. Other head elements may be provided. Each head element has at least one mist orifice 28 formed at its center to allow for vapor/mist to be emitted through the head element (e.g. 26). As discussed above, the vapor/mist is delivered to the head assembly 18 via the mist hose 20 (after the mist/vapor is generated in other components of the system 10. There is mechanism internal to the massage head assembly 18 that drives the brush element 26 in an oscillating motion “M” as shown by the arrow. In addition to the oscillating motion “M,” the assembly 18 may also provide vibrational motion. The motion is provided to assist in the exfoliation, hydration and/or massage of the skin at a very high rate of oscillation and vibration. Now turning to FIG. 3, we can continue to examine the advancements of the present invention.
FIG. 3 is a perspective view of select internal elements of the device of FIGS. 1 and 2. The base element 12 has several operational mechanisms attached to its top surface. The reservoir tank 16 dispenses its liquid into the lower reservoir 35. The cool vapor is generated within the lower reservoir 35 and delivered to the massage head assembly (see FIG. 2) via the mist hose (see FIG. 1). The mist hose inserts into the hose socket 33; a mist aperture is located within the hose socket 33 (the vapor exits through the mist aperture).
The system has a blower motor 34 associated with it to drive the vaporized liquid out through the mist hose and massage head. The speed of the blower motor 34 is controlled by the speed control knob 36, so that the vapor volume can be adjusted to the desired level. The vapor-producing mechanism is discussed below in connection with FIG. 5; first we will review the operation of the reservoir tank and its associated operational mechanisms.
FIG. 4 is a perspective view of the tank assembly 38 of the device of FIGS. 1-3. As shown here, the reservoir tank 16 is transparent so that the fluid level can be easily monitored during use. The outlet tube 32 extends downwardly from the bottom face of the reservoir tank 16. A feed valve 41 is located at the inner opening of the outlet tube 32 to control the release of fluid out through the outlet tube 32. The feed valve 41 is spring loaded to remain closed until the tank assembly 38 is placed into the base assembly (see FIG. 5). When the assembly 38 is locked into the base assembly (see FIG. 5), the feed valve 41 will be forced upwardly (against the force of the biasing spring 43) so that the feed valve 41 will open. Additionally, a fill cap 40 is provided; to fill the tank 16, the user need simply turn the tank 16 upside down, remove the fill cap 40, and fill through the fill opening 45.
An important feature of the device of the present invention is the ability to combine water with other ingredients within the reservoir tank 16. For example, extracts and essential oils can be added to the water in the reservoir tank 16; the liquid mixture can then be vaporized and delivered to the skin through the massage head assembly to improve the rate of absorption of the additive skin care ingredients.
The reservoir tank 16 is preferably defined by a latch element 42 extending from the upper portion of one of the sidewalls of the tank 16. The latch element 42 is designed to cooperate with the latch catch 30 (see FIG. 2) to secure the tank assembly 38 in its seat position in the upper housing 14 (see FIG. 2). To release the latch element 42, one need only press the free end of the catch element 42 towards the attachment point of the latch element 42 (on the tank 16). If we now turn to FIG. 5, we can continue to examine the novel features of the present device and system.
FIG. 5 is a perspective view of the base assembly 44 of the device of FIGS. 1-5. The main structural element of the base assembly 44 is the base element 12. The base element 12 defines a reservoir recess 46 on its upper face. Review of the previous drawing figures should make it apparent that the reservoir tank 16 outlet tube 32 will feed into the reservoir recess 46 when the tank 16 is placed in its location nestled in the upper housing 14 as depicted in FIG. 1. As such, the reservoir recess 46 will be gravity-filled with liquid so long as there is liquid remaining in the reservoir tank 16 (see FIG. 4).
The reservoir recess 46 is formed at its perimeter by the reservoir curb 48. A gasket 50 is dispersed around the upper edge of the curb 48 in order to create a leak-preventive seal between the upper housing 14 (see FIG. 1) and the base element 12.
A sonic transmitter 52 is located in the bottom of the reservoir recess 46, so that it is in fluid communication with any liquid located within the reservoir recess 46. The sonic transmitter 52 provides much of the unique functional features of the present invention, namely, that the liquid can be dispensed through the massage head as either cool vapor or heated steam. The sonic transmitter 52 is sized such that it can create sufficient mechanical vibration of the liquid in the reservoir recess 46 to vaporize the liquid. As the liquid is vaporized by the sonic transmitter 52, it is forced through the mist hose 20 (see FIG. 1) by forced air created by the blower motor 34 (see FIG. 3), and its associated blower fan. We will finally turn to FIG. 6 to complete our study of the device/system.
FIG. 6 is a cutaway side view of the massage head assembly 18 of the device of FIGS. 1-5. The massage head assembly 18 comprises a head housing 24 having an ergonomic shape for comfort during use. The face 60 of the housing 24 has a drive shaft 64 for driving the detachable element as depicted above in FIG. 2. The mist orifice 28 formed in the face 60 is supplied with vapor mist via the mist conduit 56 which interconnects the mist hose 20 with the mist orifice 28.
The mist conduit 56 is a section of heat tolerant tubing. One section of the conduit 56 passes through the heater module 58. The heater module 58 is configured to convert the cool vapor passing through the conduit 56 into steam before the vapor stream reaches the mist orifice 28. The heater module 58 can be selectively turned on or off using the switch buttons 66 located on the back of the housing 24. There could also be an adjustable thermostat that allows the user to adjust the amount of heat generated by the heater module 58 (and therefore the temperature of the vapor). As discussed above, the ability to provide cool vapor or heated steam through the face 60 of the massage head assembly 18 is unique to the present invention and is a sought-after feature previously unavailable in the prior devices and systems.
At least three function modes can be selected for device operation—vapor only (hot or cool), oscillation/vibration of drive motor 62 (no vapor), and both vapor and oscillation/vibration.
Although not depicted here, it is noted that power to the device 10 could be provided via internal batteries or from an external power source (i.e. from a wall socket).
Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiment can be configured without departing from the scope and spirit of the invention. Therefore, it is to be understood that, within the scope of the appended claims, the invention may be practiced other than as specifically described herein.
