Abstract

A power optimization electronic cigarette device is configured to be reusable for a limited number of refills through use of an easily accessible liquid refilling structure, before ultimately becoming disposable. The electronic cigarette device takes advantage of multiple heating wires that can be selectively operated to vaporize the liquid solution. The selective use of one heating wire, from two or more heating wires serves to extend the life span thereof. A sensor detects the air flow generated from inhaling through the electronic cigarette and triggers the heating wires to generate heat while the electronic cigarette is in use. In another power optimization function, the electronic cigarette device comprises a circuit board that detects available power in a battery, and an illumination member that variably illuminates to indicate remaining battery power. The electronic cigarette also provides a USB charging port for recharging the battery.

FIELD OF THE INVENTION

The present disclosure generally relates to electronic cigarettes, and more particularly relates to a power optimization electronic cigarette device. More so, the present disclosure relates to an electronic cigarette device that is reusable for a limited number of refills through use of a liquid solution refilling structure, before ultimately becoming disposable. Still more particularly, the electronic cigarette device optimizes battery power consumption through use of multiple heating wires that can be selectively operated to vaporize the liquid solution.

BACKGROUND OF THE INVENTION

The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present disclosure, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.
Generally, an electronic cigarette (“e-cigarette”) is a smoking apparatus that mimics a traditional tobacco cigarette smoking, by producing smoke replacement that may be similar in its physical sensation, general appearance, and sometimes flavor (i.e., with tobacco fragrance, menthol taste, added nicotine etc.). A battery portion of the electronic cigarette includes a controller and battery for powering the device and a cartomizer portion generates vapor and/or an aerosol mist (individually or collectively, “airborne substance”) that is a replacement for cigarette smoke, In particular, the cartomizer may use heat (e.g. a heating element), ultrasonic energy, or other means to vaporize, evaporate, and/or atomize a liquid solution or e-liquid (for example including propylene glycol, or glycerin, for example including taste and fragrance ingredients) into an airborne substance that mixes with air inhaled through the e-cigarette into a user's mouth.
Oftentimes, a component in the cartomizer portion that generates the airborne substance is referred to as an aerosol mist generator. The electronic cigarette may be powered by a power source, such as a battery which provides current for the heating. The power source may be difficult to regulate and result in a shorter lifespan for the electronic cigarette by requiring re-charging. The e-liquid may be kept in a small container, and during the puff some of it is heated while being dose to and around a heating coil. The heated e-liquid loses its high viscosity, and then is prone to atomization and some evaporation and/or vaporization, generating the “smoke” to be inhaled by the user. It is known in the art that some electronic cigarettes are of the disposable variety. Disposable electronic cigarettes are not used once the e-liquid is exhausted.
The problem with these electronic cigarettes is that they are not refillable, and thus not reusable, even a small number of times. Some other electronic cigarettes are designed to be reusable and last for a long time. However, they are much more expensive than disposable e-cigarettes. Furthermore, the prior art electronic cigarettes do not have switchable heating elements and a light-emitting diode (“LED”) illumination that indicates power capacity of the battery. Even though the above cited electronic cigarettes meet some of the needs of the market, a power optimization electronic cigarette device that is reusable for a limited number of smokes through use of a liquid solution refilling structure, before ultimately becoming disposable; optimizes battery power consumption through use of multiple heating wires that can be selectively operated to vaporize the liquid solution; and includes a sensor that detects air flow from inhaling the cigarette before triggering operation of the heating wires, a circuit board assembly that detects available battery power through use of a sensor and alerts to an illumination member that variably illuminates to indicate the remaining power for the battery, and a USB charging port is still desired.
Accordingly, there is a need for a new type of e-cigarettes that are refillable with e-liquid and become disposable after a small number of refills. The new type of e-cigarettes is less costly to consumers and also reduces electronic waste compared to single-use disposable e-cigarettes. Furthermore, there is a need for a new type of e-cigarettes that are reusable and disposable and include switchable heating elements. In addition, there is a need for a new type of e-cigarettes that are reusable and disposable and include switchable heating elements and an LED indicator.

Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Specific dimensions and other physical characteristics relating to the embodiments disclosed herein are therefore not to be considered as limiting, unless the claims expressly state otherwise.
A power optimization electronic cigarette device 100 is referenced in FIGS. 1-22B. The device 100 includes heating wires 300 a-b, shown in FIGS. 3 and 10D, which can be selectively operated to vaporize and/or atomize the liquid solution 212 into an inhalable mist. The connectivity of an electrical system 150 which is adapted to be housed within a housing 102 of the assembled device 100, is best seen in FIG. 101 , in which the electrical system is shown without the housing 102. In particular, a positive terminal of a battery 222 is electrically connected to a sensor and light circuit board 1504 of a sensor and light board assembly 306 through a system supply wire 220. The sensor and light circuit board 1504, in turn, is electrically connected to the battery 222 through the system supply wire 220, and to a switch circuit board 224 of a switch board assembly 305 through a plurality of transmission wires 230, which are collectively indicated at 230 in each of FIGS. 2A, 10D-F, 15, and 16 and further identified in FIG. 10F as a switch board supply wire 232 and heating current supply wires 234 a and 234 b.
The electronic cigarette device 100 further includes an air pressure sensor/switch 1503, comprising an air pressure sensor and an electrical switch, the air pressure sensor being operatively connected to the switch so as to cause the switch to close or remain closed when the air pressure sensor detects pressure below a threshold air pressure, and to open or remain open when the air pressure sensor detects pressure at or above the threshold air pressure. The air pressure sensor/switch 1503 is operatively connected to the sensor and light circuit board 1504 to alternately connect and disconnect the system supply wire 220 to and from the switch board supply wire 232. Thus, only when the air pressure sensor/switch 1503 detects a pressure drop associated with a user drawing air through device 100, the air pressure sensor/switch 1503 will dose, thus completing a circuit and allowing current to be transmitted from the sensor and light circuit board 1504 to the switch circuit board 224 through the switch board supply wire 232. The switch board supply wire 232, depicted schematically in FIG, 10F, comprises at least one of a plurality of transmission wires 230 connected between the sensor and light circuit board 1504 and the switch circuit board 224, shown in FIGS. 2A, 10D, and 10E. The switch circuit board 224 is adapted and configured to feed the received current back to the sensor and light circuit board 1504 through a heating current supply wire 234 a or 234 b, comprising two of the transmission wires 230, specifically identified in the schematic circuit diagram of FIG. 10F, which respectively correspond to a selected one of the heating wires 300 a-b. The sensor and light circuit board 1504 is adapted and configured to further direct the received current through a respective one of two heating lead wires 225 a and 225 b, which is connected to (or in an alternative embodiment not shown, constitutes a portion of) a respective one of heating wires 300 a-b, as shown in FIG. 10D, to direct current therethrough and thereby generate heat. Allowing a user to switch to the other heating wire after one is worn out is believed to increase the useful lifespan of the device 100, while also reducing power consumption.
The device 100 also includes a mouthpiece 108, shown in FIG. 5A. As seen in FIG. 2A, the mouthpiece 108 detachably attaches to a container 210 via a mouthpiece connector 110, which may, for example, be a threaded connector. The mouthpiece 108 is the portion of the device that a user can insert into her/his mouth during the inhalation of the atomized liquid solution 212. The mouthpiece 108 defines a mouthpiece air passageway 502 running therethrough from a proximal mouthpiece opening 503 to a distal mouthpiece opening 504, which serves to enable passage of air through the housing 102 as air is drawn in by the smoker. In one alternative embodiment, the amount and speed of air flow permitted into the atomizer is adjustable through a size adjustable mouthpiece air passageway.
Additionally, the device 100 provides a visual indicator of the level of the power capacity of the battery 222, or other power source used therein. At least one illumination member 1502 illuminates with variable colors, intensities, and patterns to indicate the remaining battery power. Additional functionalities provided by the device 100 may include an integrated USB port 1400 for charging the battery 222, as shown mounted to the proximal side of the switch circuit board 224 in FIGS. 3 and 14 .
The device 100 is reusable for a limited number of refills of the liquid solution 212, before ultimately becoming disposable. This is possible due to the location and accessibility of a liquid solution container 210. The liquid solution container 210 is defined at least in part by at least a portion of a proximal housing member 101 of the housing 102 and at least a portion of an inlet tube 208. The proximal housing member 101 may be permanently connected to a distal housing member 103, which houses the battery 222 and the switch and sensor and light board assemblies 305, 306. The liquid solution container 210 has a cylindrical outer sidewall 217 and an annular distal end wall 219 formed by portions of the proximal housing member 101 the annular distal end wall 219 being connected to and extending radially inwardly from the cylindrical outer sidewall 217 and circumscribing a hole 221. Preferably, the proximal housing member 101 is transparent, at least over the portions of the proximal housing member 101 that comprise the outer sidewall 217 and distal end wall 219 of the liquid solution container 210, so that a level of liquid solution, as well as the color of light from a battery power capacity level indicator light (illumination member 1502, described further below), are discernible through portions of the proximal housing member 101 to a person of normal, unaided vision. For example, at least portions, or the entirety of the proximal housing member 101 may be formed of borosilicate glass. In this manner, a user can readily see when the liquid solution 212 is low and ready to be replenished, thereby creating a more consistent and optimal atomization, promoting a mist that offers a full flavor. In one embodiment, the liquid solution 212 may include an e-liquid having a mixture of propylene glycol, glycerin, nicotine, and flavorings.
The hole 221 in the proximal housing member 101 is adapted to receive the inlet tube 208. In the assembled device 100, a proximal portion 602 a of the inlet tube 208 is inserted through the hole 221 so that a distal portion 602 b of the inlet tube 208 abuts a distal side of the distal end wall 219. A portion of the inlet tube 208 thus comprises a cylindrical inner sidewall 223 of the container 210 that is generally coaxial with and spaced radially inwardly of the outer sidewall 217 of the container 210. An annular fluid chamber 213 is thus defined by container 210, the fluid chamber 213 extending radially from the outer sidewall 217 to the inner sidewall 223 and longitudinally from distal end wall 219 to an annular container opening 226, shown in FIG. 2A, that extends radially from a proximal end of at least one of the outer sidewall 217 and the inner sidewall 223 to the other wall. When the mouthpiece 108 is attached to the container 210, the mouthpiece connector 110 covers the container opening 226, such that the fluid chamber 213 can be exposed by detaching the mouthpiece connector 110 from the container 210 and removing the mouthpiece 108 and mouthpiece connector 110 from the container 210. Thereafter, the liquid solution 212, such as an e-liquid, can be introduced into the fluid chamber 213 of the liquid solution container 210.
As shown in FIG. 1 , the device 100 comprises an elongated housing 102, having a generally uniformly circular cylindrical outer surface, which serves as the protective cover that contains the components. In alternative embodiments, an elongated rectangular, triangular, or irregular outer surface may also be used. The outer surface of the housing 102 also serves as a gripping surface, such that the device 100 can be held, manipulated, and smoked. Turning now to FIG. 4A, the housing 102 includes a distal housing member 103 providing a substantially rigid sidewall 104 that defines a cavity 400, The sidewall 104 extends between a proximal end 106 c and an opposing distal end at the distal end 106 b of the housing 102. FIGS. 4B-4C are side views and sectional views, respectively of the distal housing member 103. The distal housing member 103 is operatively coupled to the proximal housing member 101 via, for example, a permanent interference fit connection. Thus, as illustrated in FIGS. 2A and 2B, a distal skirt 105 of the proximal housing member 101 is inserted into a proximal end of the distal housing member 103 to form a permanent interference fit when the device 100 is assembled. Alternatively, the distal housing member 103 may be detachably connected to the proximal housing member 101, such as by a threaded or otherwise detachable connection.
In one non-limiting embodiment, the housing 102 is defined by a tubular shape. The tubular shape of the housing 102 is dimensioned approximately like a standard cigarette—between 70-120 mm long. The housing 102 may also be constructed from stainless steel, including SUS304 steel. However, in other embodiments, other metal or polymer material may also be used. The cavity 400 is sized and dimensioned to enable passage of air flow from the distal end 106 b to the proximal end 106 a.
In one implementation, the mouthpiece 108 includes a pair of concave sidewalls joined at a wide end 500 a to form an opening 504, and joined at a narrow end 500 b to form the mouthpiece air passageway 502. Air flow and mist from the atomized liquid solution freely pass through the opening 504 and the mouthpiece air passageway 502. Specifically, the structure of the mouthpiece 108 is configured to enable the lips to purse while sucking/inhaling through the mouthpiece air passageway 502. This configuration is sized to fit comfortably into the mouth of the smoker, and allow for sucking and inhaling motions by the lips, i.e. smoking articulations by the mouth.
Turning to FIG. 21A, the device 100 can also provide an outlet seal 216 disposed between the wide end 500 a of the mouthpiece 108 and the proximal, outlet end of the inlet tube 208. The outlet seal 216 is configured to enable more efficient air flow, and prevent seepage of the liquid solution 212 from the mouthpiece 108 (See FIG. 21A). As FIGS. 21B-21C show, the outlet seal 216 has a wide base 2100, and a narrow tube 2102 that fits into the proximal end of the inlet tube 208 and defines an outlet seal air passageway 2103 in fluid communication with the mouthpiece air passageway 502 and with a heating wire support pipe air passageway 203, described further below.
However, variously shaped and constructed sealing components may also be used between any combination of the discussed components to prevent leakage of liquid solution 212, and to create a tighter cavity for the air flow. Furthermore, in order to assist the user in a comfortable smoking experience, the mouthpiece 108 may be fabricated from a plastic resin material configured to help inhibit high temperatures. In one non-limiting embodiment, the plastic resin material comprises a cyclohexylene dimethylene terephthalate glycol.
As mentioned above, the annular fill opening 226 of the fluid chamber 213 is exposed after the mouthpiece connector 110 is detached from the inlet tube 208. Liquid solution 212 can then be introduced into the fluid chamber 213 through the annular fill opening 226. As illustrated in FIGS. 2A and 2B, the proximal portion 602 a of the inlet tube 208 extends along the length of the liquid solution container 210 and comprises its inner sidewall 223, the fluid chamber 213 thus being formed between the inlet tube 208 and portions of the proximal housing member 101 that comprise the outer sidewall 217 and distal end wall 219 of the container 210. A sectioned view of the inlet tube 208 is shown in FIG. 6B, with the narrow proximal portion 602 a and the wide distal portion 602 b together defining a continuous inlet tube volume 600 that extends longitudinally through both portions. As illustrated in FIG. 2A, the distal portion 602 b comprises a flange that abuts a distal side of the distal end wall 219 of the container 210 when the device 100 is assembled. The inlet tube 208 further incorporates a set of inlet holes 214. The inlet holes 214 allow the liquid solution 212 to flow into the inlet tube volume 600. In one implementation, the inlet tube 208 is made of copper. In other embodiments, other materials may be used for fabrication of the inlet tube 208.
As shown in FIG. 7 , the device 100 utilizes a wicking member 204 for regulating the flow of the liquid solution 212. The wicking member 204 is disposed inside the inlet tube 208 and absorbs the liquid solution 212 that has flown into the inlet tube 208 through the inlet holes 214. The wicking member 204 is configured to absorb some amount of the liquid solution 212, prior to atomization thereof. The wicking member 204 is in the form of a sleeve having a longitudinal through hole 702.
For enhanced connectivity of the structure, as shown in FIG. 8A , a proximal connector 110 is provided to detachably connect the mouthpiece 108 and the inlet tube 208. The proximal connector 110 has a threaded inner surface 800 and an outer gripping surface 802, as shown in FIG. 8A. The outer gripping surface 802 may optionally be ribbed (not shown), to facilitate gripping and turning the proximal connector 110 to attach and detach it from the inlet tube 208. In one non-limiting embodiment, the proximal connector 110 comprises a copper material and an electroplated surface. However, in alternative embodiments, other materials and connecting features are possible.
As illustrated in HG. 9, the device 100 provides a battery 222 that is operatively disposed in the cavity of the housing 102. The battery 222 is configured to generate electrical power for heating the heating wires 300 a-b, and powering components, such as the sensor and various circuit boards, described below. The battery 222 is replaceable and, in some embodiments, rechargeable. In one non-limiting embodiment, the battery 222 is operable for about 850 milliamp hours (mAh). In other embodiments, the battery 222 is a coin battery 222. However, any internal or external power source may also be used.
Referring to FIG. 3 , the device 100 includes heating wire subassemblies 206 a-b for atomizing the liquid solution 212. As described here, the heating wire subassemblies 206 a-b are supported by an insulative heating wire support pipe 202, the heating wire support pipe defining a heating wire support pipe air passageway 203 extending longitudinally therethrough, in fluid communication with the outlet seal air passageway 2103, described previously, and with an inlet seal air outlet passageway 201, described further below. Each heating wire subassembly 206 a-b includes a respective heating wire 300 a-b wound around a respective support pin 207 a-b to form a respective heating coil 301 a-b, as illustrated in FIG. 10A for heating wire subassembly 206 a. The two support pins 207 a-b are supported in respective guide holes 209 a-b formed in an heating wire support pipe 202, the guide holes 209 a-b being oriented so that the heating coils 301 a-b are disposed perpendicular to each other when the support pins 207 a-b are supported therein, each heating coil 301 a-b being disposed at least substantially within the heating wire support pipe air passageway 203 (see FIG. 11A), to allow heat from the heating coil 301 a-b to render airborne, such as by vaporization or atomization, an inhalable substance to produce an inhalable stream of air and the airborne substance within the heating wire support pipe air passageway 203 The heating wire support pipe 202 further includes wire guide channels 215 a-b formed on its peripheral surface, The heating wire subassemblies 206 a-b are configured to have their respective heating wires 300 a-b alternately energized, so that the heating coils 301 a-b alternately heat the liquid solution 212 for atomization. Each heating wire subassembly 206 a-b is operatively connected to the battery 222, receiving electrical power, or current, which is selectively directed through the heating wires 300 a-b, thereby generating heat in the respective heating coils 301 a-b, due to the electrical resistance of the material of the heating wires 300 a-b.
In one embodiment, shown in HG. 10E, each heating wire subassembly 206 a operatively connects to a respective one of two cathode posts 211 a-b of the sensor and light circuit board 1504, through a permanent connection of the respective heating lead wires 225 a-b to respective cathode posts 211 a-b, and a permanent connection of the respective heating wires 300 a-b to the respective heating lead wires 225 a-b. When a respective cathode post 211 a-b is energized with current, the current is directed through the respective heating wire 300 a-b to a common ground wire 236, shown in FIGS. 10D-E and depicted schematically in FIG. 10F. The heating wires 300 a-b have electrical resistance, so that heat is generated when electric current flows through the respective heating coils 301 a-b. This heat in turn generates vapor and/or mist from the e-liquid.
Each heating wire support pin 207 a-b is, at least partially, wrapped with a wicking material 218, such as cotton, as shown in FIGS. 10D-E. The wicking material 218 is used to wick the liquid solution 212 from the wicking member 204, through the respective guide holes 209 a-b, and into the heating wire support pipe air passageway 203, to be heated by the respective heating coil 301 a-b and thus rendered airborne (such as by being vaporized or atomized) to be carried in an inhalation air flow along an air flow path P shown in FIG. 2B. In one embodiment, the two heating wires 300 a-b are supported on the insulative wire support heating wire support pipe 202, with the heating wires 300 a-b being seated in a respective one of wire guide channels 215 a-b. The wire guide channels 215 a-b may have such orientations as may be convenient for guiding wires 300 a-b away from respective guide holes 209 a-b. In one implementation, the heating wire support pipe 202 is made of white fiberglass, whose conductive thermal resistance serves to insulate the surrounding air, liquid solution, and device components from the heat of the energized heating coil 301 a or 301 b.
The heat from the heating wires 300 a-b is sufficient to atomize the liquid solution 212 into a mist. In one non-limiting embodiment, the heating wires 300 a-b comprise a nickel-chromium alloy material, It is the electrical power from the battery 222 that actuates the heating wires 300 a-b to generate heat, In one embodiment, only one heating wire 300 a, 300 b is selected to be electronically connected with the battery 222 and be heated until it is worn out and can no longer generate sufficient heat for atomizing the e-liquid. Then, the other heating wire 300 a, 300 b is electrically connected to the battery 222. Dual heating elements, embodied as heating wires 300 a-b, extend the life span of the device 100, and thus avoid the immediate disposal of the device 100 when one heating element reaches the end of its life.
The heating wire support pipe 202 is further illustrated in FIGS. 11A-B. The heating wire support pipe 202 is utilized for carrying and orienting the first and second heating wires 300 a, 300 b. The insulative wire support heating wire support pipe 202 is disposed longitudinally inside the channel 702 of the wicking member 204 and makes contact with the surface of the channel 702. The insulative wire support heating wire support pipe 202 is made of white fiberglass material. The fiberglass material is known in the art to withstand and insulate against the high temperatures resulting from the heat generated by the heating coils 301 a-b.
To prevent leakage of the liquid solution 212 between the components, the device 100 provides various silica gel seals, For example, illustrated in FIG. 12 is an O-ring seal 302, at least one of which is disposed between the inlet tube 208 and the container 210, as shown in FIG. 2A. The O-ring seal 302 is configured to help prevent leakage of the liquid solution 212.
Yet another seal structure is an inlet seal 200, shown in FIG. 13 . As illustrated in FIG. 2 , inlet seal 200 that is disposed adjacently to the first O-ring seal 302. The inlet seal 200 is configured to help prevent leakage of the liquid solution 212 from the wicking member 204. The inlet seal 200 may define at least one air flow passageway. In one embodiment, as shown in FIG. 13C, the inlet seal 200 defines at least one inlet seal air inlet passageway 1300 that is configured to permit passage of air flow from the cavity 400 into the inlet seal 200, along a portion of an inhalation air flow path P, illustrated in FIG. 2B, which extends from the distal end 106 b of the housing 102 to the proximal end 106 a of the housing 102. The size of the inlet seal air inlet passageways 1300 helps regulate the amount of air flow through the device 100. FIG. 13D is a longitudinal cross-sectional view of an exemplary inlet seal 200 having a generally cone-shaped distal head 1302 and a proximal stem 1304, the distal head 1302 having a narrow distal end 1303 and a wide proximal end 1305, and the proximal stern 1304 being generally coaxial with and extending proximally from the proximal end 1305 of the distal head 1302. The at least one seal passageway 1300 extends generally radially inwardly from an outer periphery of the cone-shaped distal head 1305 to meet an inlet seal air outlet passageway 201, significantly larger in diameter than the inlet seal air inlet passageway 1300. The inlet seal air outlet passageway 201, in turn, is in fluid communication with the heating wire support pipe air passageway 203. to permit air to flow from the interior of the distal housing member 103 through seal passageway 1300 to the inlet seal air outlet passageway 201, and from the inlet seal air outlet passageway 201 to the heating wire support pipe air passageway 203 when a user inhales through the mouthpiece 108. In addition, the inlet seal 200 comprises wire channels 1301 (four are included, as seen in FIG. allowing for two alternate orientations of the inlet seal 200) to permit the respective heating lead wires 225 a-b to extend therethrough from the sensor and light circuit board 1504 to connect to the respective heating wires 300 a-b. In one embodiment, the O-ring seal 302 and the inlet seal 200 comprise a silica gel material that is configured to withstand high temperatures. However, other materials may also be used in other embodiments.
Turning now to FIG. 22A, the device 100 further includes a sensor and light board seal 304. The sensor and light board seal 304 has a disc-like shape, with flexible ribs 2200 at the periphery to create a seal with the inner surface of the distal housing sidewall 104, an inner circumferential groove 2202 shaped to retain the sensor and light circuit board 1504, and a plurality of longitudinal sensor and light board seal air passageways 2204, spaced radially outwardly and about the circumference of the inner circumferential groove 2202, to permit an inhalation air flow to pass around the sensor and light circuit board 1504, through the sensor and light board seal 304, for example along the air flow path P, shown in FIG. 2B, which passes through one of the air passageways 2204. Variously shaped and constructed sealing components may also be used between any combination of the discussed components to prevent leakage of liquid solution 212, and to create a tighter cavity for the air flow.
The device 100 also includes a USB port 1400, which is mounted to the proximal side of the switch circuit board 224 and adapted to be connected with a USB cable. The USB port 1400 is at least partially exposed to the exterior of the housing 102, such as through an opening 107 in the distal housing member 103, as depicted in FIG. 3 , such that docking a cable thereto is facilitated.
Referring to FIG. 15 , the device 100 also provides the unique feature of an integrated sensor and light board assembly 306. The sensor and light board assembly 306 is a printed circuit board assembly (“PCBA”) that is disposed in the cavity of the housing 102. The sensor and light board assembly 306 includes a sensor and light circuit board 1504 (a printed circuit board or “PCB”), a battery power capacity level indicator illumination member 1502 (such as an LED), and an air pressure sensor/switch 1503. The sensor and light circuit board 1504 is electronically coupled to the battery 222. The pressure sensor/switch 1503 is adapted to respond to a pressure change caused by airflow that enters the housing 102 through a distal cover 111. The sensor and light circuit board 1504 being configured to sense or otherwise detect (such as by tracking battery output over time to calculate used power capacity) a level of remaining power capacity of the battery 222. Based on the remaining power capacity level of the battery (i.e., the remaining electrical energy that the battery has the capacity to provide, as may be expressed as a percentage of its fully charged capacity, which may also be referred to herein as “charge level”), the illumination member 1502 is turned on in different colors, to direct differently colored light toward the distal end wall 219 of the container 210, In one implementation, when the charge level of the battery 222 is over, for example, 50%, the illumination member 1502 illuminates in green color. When the charge level of the battery 222 is between, for example, 25% and 50%, the color is yellow or amber. When the charge level of the battery 222 is below, for example, 25%, the illumination member 1502 illuminates in red. Alternatively, the sensor and light circuit board 1504 incorporates multiple illumination members 1502 (e.g., separate LEDs), each of which is configured to illuminate in a single color, the circuit board 1504 comprising logic to direct current to a selected LED according to the detected charge level of the battery 222. The color of the light is visible to the user since at least the portion of the proximal housing member 101 that comprises the outer sidewall 217 and the distal end wall 219 of the container 210 is transparent. Thus, light from the illumination member 1502 may further produce an appealing visual effect by shining through and illuminating liquid solution 212 present in the fluid chamber 213. A perspective view of the sensor and light board assembly 306 is illustrated in FIG. 16 .
To switch between the heating wires 300 a-b for heating the liquid solution 212, the device 100 includes the switch board assembly 305, which comprises a switch 1700 mounted on a switch circuit board 224, as shown in the exploded view of device 100 of FIG. 3 . Switch 1700 is also depicted separately in FIG. 17 . In an embodiment, the switch circuit board 224 is a PCB. As previously explained, the switch circuit board 224 is configured to direct current to a selected one of the heating wires 300 a-b.
The previously introduced distal cover 111 attaches to the distal end 106 b of the housing 102 (See FIGS. 1-3, 17-18C). The distal cover 111 is operative to allow a user to control the selective engagement of the heating wires 300 a-b with the power supply. The distal cover 111 comprises a stationary cover member 112 and a rotatable cover member 114 that rotatably attaches to a distal side of the stationary cover member 112. The rotatable cover member 114 further comprises a textured panel 1904, which forms a distal end of the assembled device 100 and may look and feel similar to the terminus of a standard tobacco cigarette (FIG. 19D). The textured panel 1904 thus provides a realistic look and feel to the distal end of the electronic cigarette device 100. In one embodiment, the rotatable cover member 114 comprises a plastic resin material configured to resist high temperatures.
The stationary cover member 112 has a generally hollow cylindrical shape and includes a proximal section 1800, a distal section 1802, and a midsection 1807 formed between the proximal section 1800 and the distal section 1802. An outer surface of the proximal section 1800 is adapted and configured to fixedly insert into the distal end 106 b of the housing 102, and an inner surface of the proximal section 1800 is adapted and configured to surround the periphery of the switch circuit board 224 so as to prevent the switch circuit board 224 from rotating axially when mounted in the interior of the proximal section 1800.
while the rotatable cover member 114 is adapted and configured to connect rotate in a first direction and a second direction relative to the stationary cover member 112. In addition, the rotatable cover member 114 is operatively connected to a rotatable switch member 1702 of the switch 1700 by a protrusion 116 that engages a slot 1704 of the rotatable switch member 1702. Thus, manual rotation of the rotatable cover member 114 rotates the switch 1700 (or a rotatable component thereof) relative to the switch circuit board, so as to actuate the switch 1700 to trigger the switch circuit board 224.
The rotatable cover member 114 and the stationary cover member 112 include certain complementary features to facilitate their connection and limited relative rotation. In particular, the rotatable cover includes a cylindrical inner wall 1902 that extends proximally from a proximal side of the textured panel 1904, and the stationary cover member 112 includes a generally annular distal section 1802 into which the inner wall 1902 inserts axially to axially align the stationary and rotatable cover members 112, 114. In addition, the rotatable cover member 114 includes a stop 1903 that engages a circumferential stop channel 1803 formed in a distal section 1802 of the stationary cover member 112, so as to permit the stop 1903 to move circumferentially along the stop channel 1803, from a first switch actuator position abutting a first end 1804 to a second switch actuator position abutting a second end 1805 of the stop channel, as the rotatable cover member 114 rotates. The abutment of the stop 1903 against the first and second stop channel ends 1804, 1805 prevents the stop 1903 from moving beyond the circumferential span of the stop channel, thus preventing the rotatable cover member 114 from rotating beyond the extremes of an angular range of rotation,
In particular, when the rotatable cover member 114 rotates in the first direction until the stop 1903 abuts one of the stop channel ends 1804, 1805, the rotatable switch member 1702 reaches a first switch position that triggers the switch circuit board 224 to return current to the sensor and light circuit board 1504 through a heating current supply wire 234 a corresponding to the heating wire 300 a, thereby causing electric current to flow through heating wire 300 a to generate heat in heating coil 301 a. When the rotatable cover member 114 and rotatable switch member 1702 rotate in the second direction until the stop 1903 abuts the other of the stop channel ends 1804, 1805, the rotatable switch member 1702 reaches a second switch position that analogously triggers the switch circuit board 224 to return current to the sensor and light circuit board 1504 through a heating current supply wire 234 b that corresponds to the heating wire 300 b, so as to be directed to the heating wire 300 b, so that heat is generated in heating coil 301 b. Abutment of the stop 1903 against the first or second stop channel end 1804, 1805 provides a tactile indication to the user that the switch 1700 is in the corresponding first or second switch position, as the user can feel that the rotatable cover member 114 cannot rotate any farther. It will be understood that it is possible to achieve the same or equivalent switching functionality by way of other switch and circuit designs, and such other switch and circuit designs are within the spirit and scope of the present disclosure.
In addition, at least one air inlet notch 1806 is formed in a proximal section 1800 of the stationary cover member 112. The air inlet notch 1806 is sized and dimensioned to enable entry of air into the distal end 106 b of the housing 102, whereby air drawn through the air opening of the mouthpiece 108 and the air inlet notch 1806 of the stationary cover member 112 generates the air flow. In one alternative embodiment, the amount and speed of air flow permitted into the atomizer is adjustable through the air inlet notch 1806, which can be size adjusted.
In the assembled device 100, a metallic ring 308 (shown separately in FIG. 20 ) is disposed adjacent to a distal side of the switch circuit board 224 and retained within and in axial alignment with the distal section 1802 of the stationary cover member 112, a distal end of the metallic ring 308 abutting a proximal face of a radially inwardly extending lip 1808 at a distal end of the distal section 1802. In one non-limiting embodiment, the metallic ring 308 comprises a copper material and an electroplated surface.
In operation, the housing 102 is oriented with the proximal end 106 a upwards, and the distal end 106 b downward, aligned with the housing 102 in a vertical position, such as shown in FIG. 1 . The proximal connector 110 is rotatably removed, such that the mouthpiece 108 detaches from the housing 102. A liquid solution 212, such as a flavored e-liquid, is poured into the fluid chamber 213 to a desired level. Thereafter, the mouthpiece is securely fastened to the inlet tube 208 in preparation for atomizing the liquid solution 212 into an inhalable mist, and/or vaporizing or evaporating the liquid solution into an inhalable vapor.
The housing 102 is held between the fingers, such as between the index and middle fingers, with the proximal end 106 a of the housing 102 oriented towards the user's mouth. The user wraps the lips around the mouthpiece 108 and commences to draw in air. The unique resin plastic configuration of the mouthpiece 108, along with the heating element support pipe 202 which insulates the heating wire subassemblies 206 a-b, help prevent the lips from burning. The air is drawn through the air inlet notch 1806 in the stationary cover member 112 of the distal cover 111 into a distal region of the distal housing cavity 400, through the sensor and light board seal air passageways 2204 and into a proximal region of the cavity 400, through the inlet seal air inlet passageways 1300 and inlet seal outlet passageway 201 and into the wire support pipe air passageway 203, and finally through the outlet seal air passageway 2103 and into the mouthpiece air passageway 502. Collectively, the distal housing cavity 400 and the air passageways 2204, 1300, 201, 203, 2103, and 502 thus define a device air passageway 109, indicated in FIG. 2B, that extends throughout the interior of the device 100 from the air inlet notch 1806 to the proximal mouthpiece opening 503.
This creates air flow from the distal end 106 b to the proximal end 106 a—and thereby an air pressure drop—in the interior volume of the housing 102. When a pressure sensor/switch 1503 detects the air pressure drop, consequently actuating the battery 222 to generate electrical power upon detection of the air flow. The activated battery 222, which is connected to each heating wire subassembly 206 a-b, results in at least one of the heating wires 300 a-b heating up sufficiently to atomize and/or vaporize or evaporate the liquid solution 212 into an inhalable mist and/or vapor.
The power optimization electronic cigarette device 100 is configured to be reusable for a limited number of refills through use of an easily accessible liquid refilling structure, before ultimately becoming disposable. The electronic cigarette device 100 optimizes battery power consumption through use of multiple heating wires that can be selectively operated to vaporize the liquid solution. The pressure sensor/switch 1503 is adapted and configured to detect a pressure drop, resulting from air flow generated from a user inhaling through the electronic cigarette device 100, and to trigger the heating wires 300 a-b to generate heat, only when detecting a pressure drop that indicates that the electronic cigarette device 100 is in use. The selective use of one heating wire, selected from two or more heating wires, serves to extend the life span thereof. In another power optimization function, the electronic cigarette device comprises a sensor and light board assembly 306 that detects available battery power capacity, and an illumination member 1502 that variably illuminates to indicate the remaining power capacity of the battery.
