Conventional e-cigarette devices tend to rely on inducing high temperatures of a metal component configured to heat a liquid in the e-cigarette, thus vaporizing the liquid that can be breathed in. Problems with conventional e-cigarettes may include the possibility of burning metal and subsequent breathing in of the metal along with the burnt liquid. In addition, some may not prefer the burnt smell caused by the heated liquid. In addition, a conventional e-cigarette may be designed to create a substantial amount of smoke, simulated by the burnt liquid, that can be akin to second-hand smoke. It is desirable to develop devices that minimize or eliminate at least some of these problems.

Some embodiments are illustrated by way of example and not limitation in the figures of the accompanying drawings.
The following detailed description should be read with reference to the drawings, in which identical reference numbers refer to like elements throughout the different figures. The drawings, which are not necessarily to scale, depict selective embodiments and are not intended to limit the scope of the invention. The detailed description illustrates by way of example, not by way of limitation, the principles of the invention. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what is presently believed to be the best mode of carrying out the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly indicates otherwise.
Conventional e-cigarette devices tend to rely on inducing high temperatures of a metal component configured to heat a liquid in the e-cigarette, thus vaporizing the liquid that can be breathed in. The liquid typically contains nicotine and flavorings blended into a solution of 50% propylene glycol (PG) and 50% vegetable glycerin (VG), which is vaporized through an atomizer (resister) at about 200 degrees Celsius. Problems with conventional e-cigarettes may include the possibility of burning metal and subsequent breathing in of the metal along with the burnt liquid. In addition, some may not prefer the burnt smell caused by the heated liquid. In addition, a conventional e-cigarette may be designed to create a substantial amount of smoke, simulated by the burnt liquid, that can be akin to second-hand smoke.
In contrast, aspects of the present disclosure include an e-cigarette device that atomizes the liquid through ultrasonic vibrations, which produces micro water bubbles in the liquid. When the bubbles come into contact with random air molecules of high temperature, water droplets of about 2-5 microns vaporize into the air, thereby generating micro-droplets that can be absorbed through breathing, similar to breathing in a mist or vapor. For example, the ultrasonic e-cigarette of the present disclosures may produce a cool mist that contains more than 80% of H2O mixed with nicotine and other ingredients including but not limited to PG, VG, flavorings, and natural oils. In some embodiments, the nicotine mixture is less than 2% or more than 20% by volume. No heating elements are involved, thereby leading to no burnt elements and reducing second-hand smoke effects. As used herein, descriptions of “water” may refer to a liquid combination of H2O and other ingredients conventionally used in e-cigarette devices utilizing liquid mixtures.
The ultrasonic device according to the present disclosures will contact the liquid on one surface and spray it out the other surface, bursting outwards a mist that is close to room temperature. As a result, there will be no burnt flavor of any kind for the user (as opposed to current products). This allows for aspects of the present disclosures to produce less smoke, making it possible to be used anywhere without disturbing other people.
In some embodiments, the e-cigarette device will channel the mist from 1 to 6 of these ultrasonic disks (may vary by product line and by manual or automatic setting adjustments) from one or more air channels, which are like semicircular straws enclosing the spraying side of the disks. On the opposite side of the disks, a thin water channel will be attached to them. In some embodiments, the e-cigarette device will have the water channel between or mounted on one side of the disks. The combination of the water channel (3), disks (5), and airway (6) & (8) is called the emission chamber. In some embodiments, this emission chamber is removable for ease of cleaning.
Surrounding the emission chamber or closely attached to it is a liquid container (9) & (10). The liquid container includes a movable liquid seal (7) that stays on the surface of the liquid. The seal tells the user the current liquid level remaining. The movable seal (7), together with the thin water channel (3) will ensure the liquid is continuously supplied to the disks (5) because atmospheric pressure will push down on the liquid seal (7). In some embodiments, a transparent liquid container (9) & (10) and a semi-transparent emission chamber are present so that the user can see the liquid level as well as the ultrasonic vaporization process.
In some embodiments, the airways (6) & (9) are connected to the upper portion of the battery tube (13) where the circuitry (11) is located. This will allow for automatic variable output of the spray disk because the circuitry will have a mechanical component that links to the flow of air.
In summary, the e-cigarette device of the present disclosures is a more powerful version of current portable medical nebulizers, in the shape and size of current e-cigarettes and with a particular structure for effective vaporization. It is a healthier alternative to cigarettes and current e-cigarettes products.

Water Seal, Liquid Container and Water Channel (7), (9), (10), (3)

The system works by the physics of suction: as the ultrasonic spray disk 5 sprays the mist into the air channel between 6 and 8, it also uses up the water in the water channel flowing through the middle of 3. Provided that firstly there is no air or water leak between the seals 4, inner disk housing 3, and the spray disks 5, and secondly there is no air or water leak between the middle tip of the cap 2 covering the water channel in the middle of 3, conservation of mass requires the water to flow continuously from the water channel. This requires the liquid container combination of 9 & 10 to not be air sealed so that the atmospheric pressure will push the water seal 7 downward (hence the water) as the water is used up by the disks. This system works at all angles and orientation because the atmospheric pressure is strong enough to overcome the weight of the water in the container.

In some embodiments, there is ˜1 mm of space between 3 & 6 to allow placement of two seals sandwiching the spray disk 5 as well as electrical wiring or connection. Notice that the top of the disk housing combination 3 & 6 is sealed off while the bottom contains two openings to allow electrical connection with the circuitry 11 (see

In this alternative example, various components may be similar to those described in
Also, instead of using the stopper 902, one may employ a plastic bag or other flexible cartridge that has opening attachment which sits between the interface of the sprayer housing 604 and liquid container 606. The flexible cartridge may be configured to reduce in volume as the liquid in the cartridge is used up. This way, disposable cartridges may be utilized.
