Description

TECHNICAL FIELD

The disclosure is directed to a radio-frequency heating medium that may be used as part of an electronic vaporization device, such as an e-cigarette or personal vaporizer, to vaporize certain materials.

BACKGROUND

An electronic vaporization device may simulate the feeling of smoking by heating a substance to generate an aerosol, commonly called a “vapor”, that a user inhales. Vaporization provides an alternative to combustion for the delivery and consumption of various substances including, but not limited to liquids, i.e., “E-liquids,” waxes, gels and combinations thereof (singularly, “a vaporizable substance,” collectively, “vaporizable substances”). Non-limiting examples of components of vaporizable substances include: glycerin, propylene glycol, flavorings, nicotine, medicaments and combinations thereof. Vaporization may be accomplished using electronic vaporization devices, including, but not limited to, electronic cigarettes, electronic cigars, electronic pipes and electronic vaporizers (singularly “EVD,” collectively, “EVDs”).

While EVDs may reduce consumer exposure to toxins as compared to traditional smoking, there may be a cause for concern relating to consumer exposure to trace metal(s) through vapor inhalation. EVDs typically use resistive heating to vaporize the liquids in an atomizer by passing a high current through a conductor, such as a metallic coil (i.e., nickel, aluminum, silver, chromium, iron, Kanthal, Nichrome, platinum, etc.) to produce heat, thereby generating the vapor for inhalation. Such heat and harsh environments in the atomizer may cause the metallic coil to oxidize, degrade, volatilize, and/or corrode, contaminating the vapor with trace metal(s). Resistive heating may also be inefficient, as vaporization is limited to the region where the metallic coil is in contact with the wicking material, resulting in high energy consumption. Such a high energy consumption may require a long warm-up time for the atomizer to reach operating temperature and may also require the battery of the EVD to be charged and/or replaced often.

Thus, in some instances, it may be desirable to minimize the process of oxidation, degradation, volatilization, and/or corrosion of the metallic coil of the atomizer and/or to improve efficiency of an EVD. While a variety of heating mediums have been made and used, it is believed that no one prior to the inventor has made or used an invention as described herein.

SUMMARY

The unique solution that addresses the aforementioned problems is an atomizer assembly comprising a radio-frequency heating medium. The atomizer assembly may be actuated by a control unit comprising a radio-frequency signal generator circuit and a power amplifier configured to amplify the radio-frequency signal produced by the radio-frequency signal generator circuit. The amplified radio-frequency signal may be transmitted to an atomizer to thereby heat a vaporizable substance. The atomizer assembly may further comprise a temperature sensor positioned within or near the atomizer to measure the temperature of the atomizer such that temperature control logic of the control unit may adjust the amplified radio-frequency signal based on the measured temperature of the temperature sensor to maintain a desired temperature within the atomizer. Such a radio-frequency heating medium may improve the safety of the EVD by reducing the process of oxidation, degradation, volatilization, and/or corrosion of the atomizer to thereby limit consumer exposure to trace metals. The radio-frequency medium may also reduce the energy consumption of the EVD to shorten the amount of time for the EVD to reach operating temperature and/or to lengthen the life of the battery.

It will be appreciated that any one or more of the teachings, expressions, versions, examples, etc. described herein may be combined with any one or more of the other teachings, expressions, versions, examples, etc. that are described herein. The following-described teachings, expressions, versions, examples, etc. should therefore not be viewed in isolation relative to each other. Various suitable ways in which the teachings herein may be combined will be readily apparent to those of ordinary skill in the art in view of the teachings herein. Such modifications and variations are intended to be included within the scope of the claims.

FIG. 1 shows a typical EVD 500 comprising a battery compartment 510 containing a battery 512 that is removably attached to a chamber 200 by connector 514. The chamber 200 is in turn removably attached to a mouthpiece 530. The chamber may be filled with a vaporizable substance through its open top, i.e., be a “top-filled chamber,” or it may be filled with a vaporizable substance through its open bottom, i.e., a “bottom-filled chamber.” As is known in the art, some EVDs comprise a battery compartment that is permanently affixed to a chamber of an EVD.

FIG. 2 shows the chamber 200 of FIG. 1 comprising an atomizer assembly 230. The atomizer assembly 230 comprises a metallic coil 235 that can be wrapped within an absorbent wick material such that the metallic coil 235 is positioned within the absorbent wick material. In some other versions, the absorbent wick material can be inserted through the metallic coil 235 such that the metallic coil 235 is positioned about the absorbent wick material. Exemplary wick material of use may be selected from cotton, nylon, porous ceramic and combinations thereof. Extending from the atomizer assembly 230 is a vapor chimney 231, which is surrounded in part by a silicone or rubber ring 232. When the chamber 200 is assembled, the atomizer assembly 230 and vapor chimney 231 fit into the chamber 200. The chamber 200 is capped at its open top by a hollow metal ring 234 that is threaded on the inside and which serves as the attachment point of the mouthpiece 530 to the chamber 200.

Accordingly, the metallic coil 235 of the atomizer assembly 230 becomes hot when supplied with electricity from the battery compartment 510 due to its resistance to the flow of electric current. The wicking material in turn acts to transport the vaporizable substance, i.e., the E-liquid, gel or melted wax, to the metallic coil 235 to heat it and release vapor. The resulting vapor may then pass through the vapor chimney 231 to be delivered to the consumer via the mouthpiece 530.

Because heat and harsh environments in the atomizer assembly 230 may cause the metallic coil 235 to oxidize, degrade, volatilize, and/or corrode, the resulting vapor may be contaminated with one or more trace metals. Further, the resistive heating medium of the atomizer assembly 230 may further have a high energy consumption because a high current is needed to reach a high temperature in the atomizer. It may thereby be desirable to provide an atomizer assembly for use with an EVD comprising a coil-free design to prevent metal contamination and/or improve the efficiency of the EVD. Accordingly, an atomizer assembly is provided comprising a radio-frequency heating medium to heat the vaporizable substance of an EVD using radio-frequency energy instead of via a typical resistive heating method with a metal coil. The radio-frequency heating medium may thereby be used in an EVD to minimize the contamination of vapor with trace metal because the radio-frequency heating medium prevents metal from being in direct contact with the vaporizable substance and/or the wicking material. The radio-frequency heating medium may also improve the efficiency of an EVD because the radio-frequency heating medium may use less energy than is typically used in a resistive heating method with a metal coil to uniformly heat the entire wicking material. This may thereby shorten the amount of time for the EVD to reach operating temperature and/or to lengthen the life of the battery.

Referring to FIG. 3, an atomizer assembly 30 is shown for use with the EVD 500 instead of the resistive heating atomizer assembly 230. The atomizer assembly 30 comprises an electromagnetic or radio-frequency (RF) heating medium is shown comprising an electromagnetic or radio-frequency (RF) heating medium that may be used to vaporize a substance in an EVD. The atomizer assembly 30 comprises a power supply 6 coupled to a control unit 7, a waveguide 1, and a resonating cavity atomizer 3 containing a wicking material 4. In some other versions, the resonating cavity atomizer 3 is in direct contact with a vaporizable substance, instead of via a wicking material, as shown in FIG. 3A. The power supply 6 may provide a power of about 350 Watts, or other suitable amount, to provide power to operate the control unit 7. The power supply 6 may be the same power supply that is used to supply power to the EVD, such as the battery 512, or the power supply 6 may be a separate external power supply. Other suitable configurations for powering the atomizer assembly 30 will be apparent to one with ordinary skill in the art in view of the teachings herein.

The control unit 7 comprises an RF signal generator circuit 12, a power amplifier 11, and a temperature control logic 13. The RF signal generator circuit 12 may produce a high frequency RF signal or wave having an operating frequency region from about 3 kilohertz (kHz) to about 300 gigahertz (GHz), such as from about 915 megahertz (MHz) to about 2.4 gigahertz (GHz). The RF signal generator circuit 12 may then be coupled with the power amplifier 11 that can amplify the RF signal produced by the RF signal generator circuit 12. Such a power amplifier 11 may provide several benefits such as portability of the atomizer assembly 30 based on size and weight, a high-power gain, precise temperature control, and/or uniform heat distribution. The amplified RF signal is then transmitted to the resonating cavity atomizer 3 through a waveguide 1. The waveguide 1 may comprise a liquid-tight seal that is translucent to the electromagnetic energy in the operating frequency region.

The resonating cavity atomizer 3 shown in FIG. 3 comprises a Faraday-cage type design having a conductive metal configured to hold electromagnetic radiation inside the resonating cavity atomizer 3, while simultaneously allowing the flow of air and the vaporizable substance through the resonating atomizer cavity 3. This may confine the electromagnetic energy radiation inside the resonating cavity atomizer 3 to limit its exposure to a user. Such a resonating cavity atomizer 3 may create a standing wave, establishing an indefinite oscillation, to generate an operating temperature substantially instantaneously. Such temperatures may be from about 150° C. to about 600° C., from about 180° C. to about 300° C. or from about 150° C. to about 180° C. Further, the atomizer assembly may routinely reach a temperature of about 180° C. or about 200° C. Accordingly, limiting the standing wave to a small region, such as about 20 cm³ or other suitable volume, may substantially instantaneously heat the resonating cavity atomizer 3 to such high temperatures without requiring high power. The wicking material 4 inside resonating cavity atomizer 3 absorbs the vaporizable substance in the EVD through its capillarity. The absorbed substance may then be vaporized by heating the wicking material 4 to the boiling point of the substance through the radiation of RF energy produced by the RF heating medium of the atomizer assembly 30. The process of inhalation by the user through the mouthpiece 530 may create a continuous flow through the wicking material 4 while vaporizing the substance when heated.

The vaporizable substance may be prevented from entering the waveguide 1 and reaching the electronics in the control unit 7 by a liquid-tight material 5 positioned in an end of the waveguide 1 near the resonating cavity atomizer 3. The liquid-tight material 5 may be translucent to the RF signal at its operating frequency. The liquid-tight material 5 may comprise materials such as high-temperature resistive glass having a thickness less than a quarter wavelength of the operating frequency. Exemplary high-temperature resistive glass may be selected from silica, soda-lime silica, sodium borosilicate, lead-oxide glass, aluminosilicate, germanium oxide, and combinations thereof. Still other suitable materials will be apparent to one with ordinary skill in the art in view of the teachings herein. For instance, any material may be used that does not absorb a frequency that may increase vibrations of the RF signal during heating.

A temperature sensor 2 may be provided in or near the resonating cavity atomizer 3 that is configured to measure the temperature of the resonating cavity atomizer 3. The temperature sensor may be coupled with the control unit 7 such that the temperature control logic 13 of the control unit 7 may adjust or control the temperature of the resonating cavity atomizer 3 based on the temperature measured by the temperature sensor 2. For instance, the temperature control logic 13 may adjust the amplitude of the RF signal transmitted by the power amplifier 11 by increasing the amplitude of the RF signal to increase the temperature of the resonating cavity atomizer 3 and/or by decreasing the amplitude of the RF signal to decrease the temperature of the resonating cavity atomizer 3. Accordingly, the temperature control logic 13 may provide precise control of the amplitude of the RF signal to achieve the desired temperatures inside the resonating cavity atomizer 3. In some instances, the temperature control logic 13 can supply a maximum input signal to the power amplifier 11 to rapidly increase the temperature within the resonating cavity atomizer 3 until the desired temperature is reached. The temperature control logic 13 may then reduce the input signal to the power amplifier 11 to save energy consumption without compromising temperature.

Accordingly, the RF signal generator circuit 12 produces an RF signal with a wavelength in the desired operating frequency. The power amplifier 11 then amplifies this RF signal and the amplified RF signal is transmitted to the resonating cavity atomizer 3 via the waveguide 1. The Faraday-cage design of the resonating cavity atomizer 3 and/or the liquid-tight material 5 prevents the transmitted RF signal from returning to the control unit 7. The resonating cavity atomizer 3 creates a standing wave of RF energy to heat the wicking material 4 and/or vaporizable substance positioned within the resonating cavity atomizer 3. The vaporizable substance absorbed by the wicking material 4 is thereby vaporized and inhaled by a user through the mouthpiece of the EVD. The temperature of the resonating cavity atomizer 3 can be controlled to a desired temperature by operating the temperature control logic 13 to adjust the amplification of the RF signal transmitted by the control unit 7 through the power amplifier 11 based on the measured temperature of the resonating cavity atomizer 3 by the temperature sensor 2. This provides a coil-free design to heat the vaporizable substance while preventing metal contamination and improving efficiency. Still other suitable configurations for operating the atomizer assembly 30 will be apparent to one with ordinary skill in the art in view of the teachings herein.

In some versions, the Faraday-cage design of the resonating cavity atomizer 3 can be modified by having a few holes in its metal frame of dimensions significantly less than the size of the wavelength of the operating frequency. In some other versions, the resonating cavity atomizer 3 can be substituted with an atomizer 130 shown in FIG. 4 comprising a wicking material 132 positioned between a plurality of electrodes 138. In some versions, the atomizer 130 does not include a wicking material, as shown in FIG. 4A, such that the atomizer 130 may be in direct contact with the vaporizable substance. Each of the electrodes 138 comprises a plate positioned substantially parallel relative to the other electrodes 138. An opening 134 is provided underneath each wicking material 132 between the electrodes 138. The electrodes 138 are then coupled with a coaxial RF connector 136, such as a subminiature version A (SMA) connector. Accordingly, the RF connector 136 may be coupled with the control unit 7 such that the amplified RF signal produced by the control unit 7 is transmitted to each of the electrodes 138 via the RF connector 136. The electrodes 138 thereby transmit the RF energy through the wicking material 132 to heat the wicking material 132 and vaporize the substance in the EVD. The vapor is thereby substantially free of trace metals, such as nickel, aluminum, silver, chromium, iron, Kanthal, Nichrome, platinum, and combinations thereof. The RF heating medium may further be more energy efficient to shorten the amount of time for the EVD to reach operating temperature and/or to lengthen the life of the battery. Of course, other suitable configurations for the atomizer assembly 30 will be apparent to one with ordinary skill in the art in view of the teachings herein.
