Description

RELATED DOCUMENTS
• No related documents or priorities are claimed.
BACKGROUND
• This invention relates to a device for personal hygiene and for comfort. More particularly, it relates to the use of thermo-electric technology in a compact, portable, pocket-sized device for personal cooling or warming to give relief from hot flashes/overheat or chills for anyone, anywhere.
THE PROBLEM
• Portable personal cooling devices (for example a battery-operated hand-held fans, ice bags or chemical cooling or heating packs) are of limited effectiveness and therefore, not very practical when one considers how cumbersome and inconvenient they are. The purpose of this invention is to provide a personal cooling/warming system that uses solid-state electronics and is, therefore compact, fast, efficient and resilient, requiring no compressors, CFC gases or coolant coils.
• When people exert themselves in play or work, their body temperatures rapidly rise. Additionally, some physiological conditions, for example, female menopause, can cause frequent, uncomfortable sensations of chilling or overheat (“hot flashes”) accompanied by profuse perspiration. Dealing with these can be difficult and inconvenient, particularly in public places or while on the job.
• With respect to “hot-flashes,” it is common knowledge that they are often concentrated at nodes in the vicinity of points where arteries pass near the surface of the skin. (These are most often identified as being the points where pulse can be measured.) If these nodes are cooled, then relief is quickly experienced and the rapid circulation of cooled blood carries on to the brain. With this quick rush of soothing relief also often comes a disproportionately calming effect leaving the user more relaxed and confident.
• However, consistent and convenient access to such relief has been difficult. Ice cubes or chemical packs have been used to cool nodal points, but they are, as mentioned, hard to transport or preserve and can be messy or bulky to use. In example, one would be hard pressed to use bulky cooling packs or melting ice cubes while participating in sports, riding a train, giving a public presentation, or even merely walking on the street.
• This invention provides the relief desired while overcoming all the above disadvantages of prior art.
SUMMARY
• This invention comprises a thermo-electric module that, in turn, comprises a solid-state thermo-electric chip. The invention also comprises a heat-sink, a “cold-sink” and a direct current power source as well as a switch and associated hardware.
• The preferred embodiment uses two “D” size dry cells as a direct current power source incased in a housing attached to a head containing the thermo-electric module. The housing also serves as a convenient handle.
PRIOR ART
• The primary forms of prior art are battery operated cooling fans, cooling pads and hot pads.
• U.S. Pat. No. 6,125,636, issued to Taylor and Fai Lau, teaches a thermo-voltaic device mounted on a headband such that it can be affixed in the center of the forehead. The device is powered and controlled by a self-contained battery source with reversible polarity, allowing it to heat or cool the brow as the user desires. This invention is designed to be used to cool only one point on the body (the forehead) and must be used in an overt, rather than discrete, manner. Although it might be appropriate for use during sporting activities, it would not be acceptable in most social situations.
• U.S. Pat. No. 5,956,963, issued to Lerner teaches a chemical cooling unit to be worn on the wrist. This system is not controllable and is designed for use upon only one point on the body (the wrist). The chemical cooling agent may be used only once, after which it must be discarded and replaced. It cannot produce warming energy. As with the previously described (Taylor) device, it must be used in an overt, rather than discrete manner, and would not be appropriate in more formal social situations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
• The compact, convenient and solid state personal cooling/warming system of this invention as shown in the drawings wherein like numerals represent like parts throughout the several views, generally disclosed the invention in FIGS. 1 through 5.
• The overall system 100 of this invention comprises a thermo-electric module 90 that, in turn, comprises a solid-state thermo-electric chip 70. The system also includes a heat sink 40 and a “cold sink” 60, a direct current power source 15 as well as a switch 30 and standard but essential hardware means of connecting, interfacing and integrating the several parts 80 (not illustrated).
• The preferred embodiment uses two “D” sized cells 20 for the direct current power source 15 in a rounded housing 10 that may, optionally, be foldable via a hinge 55 over the thermo-electric module 90. The housing 10 also serves as a convenient handle.
• FIG. 3 shows the interface between the thermo-electric module's solid state chip and the “cold sink” in greater detail. In the preferred embodiment, the inventor also used Melcor model CP0.8-71-06L ™ as the thermo-electric chip 70. The approximate cooling area of the device is forty-thousand square millimeters or sixty square inches.
• The solid state electronic cooling thermo-electric chip is 21^st Century technology. Without bulky compressors, CFC gases and coils, the chip cools. It can cool up to sub-zero temperatures and beyond. They can be designed to various BTU capacities. Their life is at least 200,000 hours, guaranteed.
• A 30 to 50 BTU thermo-electric chip is attached to an anodized aluminum/copper heat-sink by the help of thermal epoxy. A copper or aluminum button (“cold-sink”) having a 1 to 2 inch diameter is in contact with the cold side of the chip. The chip is energized by dry cells (conventional or rechargeable) 20 housed in the handle 10. The entire apparatus is enclosed in a “hair brush” like mold. The switch 30 extends about ⅛ of an inch on one side and the heat sink is exposed to ambient air on the other side. A slide switch activates the UBKool™ personal cooling system of this invention.
• The use and operation of this device is simple and intuitive. The operator merely unfolds the device, switches it on and touches it to the desired area of the body or gently rubs it over the area for effective conduction of heat away from the skin.
• The super cold button (“cold-sink”) may be gently pressed against any spot on the human body to effectively and efficiently cool that particular area. Yet, the UBKool is so small that it can be carried in a purse or pocket or worn on the belt like a cell phone.
• The following description is intended to be non-limiting. The broad simplicity of this design makes it difficult to “design around.” Nonetheless, many changes may be made to this design without deviating from the spirit of the invention. Examples of such variations contemplated include the following:
• • 1. The shape and size of material of the various components may be modified.
  • 2. A different thermo-electric module may be used.
  • 3. The color, aesthetics and materials may be enhanced or varied.
  • 4. Additional complimentary functions and features may be added.
  • 5. A more economical version of the device may be adapted with an informational or advertising message for promotional gifts.
  • 6. A different type of handle may be provided.
• Other changes such as aesthetic alterations and substitution of newer materials as they become available, that perform substantially the same function in substantially the same manner with substantially the same result may be made without deviating from the spirit of the invention.
