DESCRIPTION

This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended electronic cigarette and/or assembly procedures for an electronic will become apparent for use with implementations of electronic cigarettes from this disclosure. Accordingly, for example, although particular electronic cigarettes are disclosed, such electronic cigarettes and implementing components may comprise any shape, size, style, type, model, version, measurement, concentration, material, quantity, and/or the like as is known in the art for such electronic cigarettes and implementing components, consistent with the intended operation of an electronic cigarette.

Contemplated herein are various embodiments of electronic cigarettes. Unless otherwise specified, the electronic cigarettes contemplated as part of this disclosure may comprise various elements and features of electronic cigarettes known in the art, such as but not limited to batteries, vaporizers, heating elements, processors, and the like. Embodiments of electronic cigarettes described herein offer numerous advantages and solve various problems common to conventional electronic cigarettes. For example, a heat sink proximate to or in combination with the mouthpiece is configured to cool down the temperature of the vapor inhaled by the user, thus providing a safer and more satisfactory vaping experience. By way of another, non-limiting example, utilizing one or more thermistors proximate the oven or heating assembly and operably coupled to a processor allow a processor to determine when a vaporizer is in use and adjust the temperature of the oven or heating assembly to accommodate the increase of ambient air within the system.

FIGS. 27-38 depict various views of a non-limiting embodiment of an electronic cigarette 50. One or more embodiments of an electronic cigarette 50 comprise a mouthpiece 60 adapted to detachably couple to the electronic cigarette. A mouthpiece 60 may comprise a heat sink 65 and a mouthpiece opening 61. More particularly, a mouthpiece 60 may comprise an external mouthpiece opening that, when coupled to the housing 54 of the electronic cigarette 50, is in fluid communication with a vapor passage 55 within the housing 54. In one or more embodiments, the at least a portion of the heat sink 65 is extends outward from an external cover of the mouthpiece 60. Accordingly, a mouthpiece 60 may be configured to partially nest within a recess 58 on the housing 54. For example, in the non-limiting embodiment shown in FIG. 27, the housing 54 comprises a housing recess 58 on a top or first end of the housing 54. In other embodiments, the housing recess 58 may be positioned elsewhere with the vapor passage 55 extending to the housing recess 58. The heat sink 65 may comprise a depth such that the heat sink 65 interfaces with a wall 57 of the housing recess 58 and an edge of the external cover interfaces with a top edge 59 of the housing 54. According to some aspects, the wall 57 of the housing recess 58 comprises a silicone covered steel wall 57 and the mouthpiece comprises one or more magnets 68 embedded in the heat sink 65 (shown in FIGS. 31 and 32) and adapted to magnetically couple the mouthpiece 60 to the housing 54. In some embodiments, the mouthpiece 60 is separate from the heat sink 65. That is, the heat sink 65 may be removed from or coupled to the electronic cigarette independent of the mouthpiece 60.

One or more embodiments of a mouthpiece 60 comprise a vapor channel 70 recessed in the heat sink 65. The vapor channel 70 is adapted to allow fluid communication from the vapor passage 55, through the vapor channel 70, to the external mouthpiece opening 61. In such an embodiment, interfacing between the heat sink 65 and the wall 57 of the housing recess 58 allows fluid communication between the vapor passage 55 and the external mouthpiece opening 61 only through the vapor channel 70 recessed within the heat sink 65. In a non-limiting embodiment, a vapor channel 70 comprises an entry point 69 aligned with the vapor passage 55 when the mouthpiece 60 is coupled to the housing 54. The vapor channel 70 may extend from the entry point 69 towards as end 62 of the mouthpiece distal or opposite the external mouthpiece piece opening 61 before reversing course and extending to the external mouthpiece 61. More particularly, the vapor channel includes two first arms 71 branching from the entry point 69 and meeting proximate the end 62 of the mouthpiece 60 distal the external mouthpiece opening 61, and two second arms 72 branching from the end 62 of the mouthpiece distal the external mouthpiece opening 61 and meeting proximate the mouthpiece opening 61 to allow fluid communication between the vapor passage 55 and the external mouthpiece opening 61.

One or more embodiments of an electronic cigarette 50 further comprise a vapor passage 55 positioned within the housing 54 and adapted to allow fluid communication between the oven, heating assembly 75, or vaporizer and the external mouthpiece opening 61. FIG. 28 shows a cross sectional view taken along line W-W of a non-limiting embodiment of an electronic cigarette 50 comprises a vapor passage 55 extending from the heating assembly 75 to the wall 57 of the housing recess 58. The oven, heating assembly 75, or vaporizer may comprise any oven, heating assembly, or vaporizer known in the art. Vapor from the oven, heating assembly 75, or vaporizer is caused to be drawn up through the vapor passage 55 when a user draws air from the mouthpiece opening 61.

One or more embodiments of an electronic cigarette comprise a temperature sensor, such as but not limited to a thermistor 88 (shown in FIG. 39). The temperature sensor may be positioned within the housing 54 proximate the heating assembly 75. In some embodiments, the temperature sensor is configured to detect an ambient air temperature when the heating assembly is activated and a temperature of air drawn into the heating assembly when a user inhales or otherwise sucks through the opening 61 of the mouthpiece 60. According to some aspects, a temperature sensor is positioned between a stainless-steel oven or other oven of the heating assembly 75 and the plastic body or other housing 54 of the electronic cigarette 50. The temperature sensor may comprise a first end exposed, which detects the ambient air when the oven is turned on as well as the temperature of any air that goes into the oven when the user inhales from the electronic cigarette. This temperature information is then communicated to a processor 190 (see FIGS. 12-13, 16-18 and 28) within the housing 54, which increases the temperature of the heating assembly 75 to quickly heat up the oven to accommodate for the lost heat by the introduction of external air. Knowing the temperature of the ambient air when the electronic cigarette 50 first turns on will set a baseline for how much the heaterill have to increase the temperature once the user inhales. For example, the colder the ambient air the hotter the heating assembly has to get.

One or more embodiments of an electronic cigarette 50 comprise a bottom cap removably coupled to the housing 54. The bottom cap 80 may be detachably coupled to the housing proximate the oven and/or heating assembly such that the bottom cap acts as an oven lid. While the cap is referenced as a bottom cap herein, it is contemplated that the bottom cap 80 may be positioned anywhere on the housing 54 of the electronic cigarette. FIGS. 33-37 show various views of a non-limiting embodiment of a bottom cap 80. In some embodiments, the bottom cap comprises a body 81, a biased button 82 extending through the body 81, one or more button channels 84 or recesses recessed on or around the button 82, and a plurality of ball bearings 83 coupled to the button 82 such that when the button 82 is pressed the plurality of ball bearings 83 retract to the bearing channel 84 to allow a portion of the button 82 to fit within the button receiver 87, and when the button 82 is released the plurality of ball bearings 83 move outside the bearing channel or recess 84 and inhibit the portion of the button 82 from exiting the button receiver 87. The housing may comprise an internal button receiver 87 positioned to receive the one or more ball bearings to detachably couple the bottom cap 80 to the housing.

Activation of the vaporizer may be initiated through operation of a sliding switch on a side of the housing 54. The sliding switch is biased to a first, rest position and is associated with the processor within the housing 54 that controls operation of the temperature and various modes of the vaporizer. Each time the sliding switch is moved from its rest position to a second, activation position, the processor 190 (see FIGS. 12-13, 16-18 and 28) records the movement as a change in state for the vaporizer. For example, if the rest position is the “up” position for the sliding switch, each time the switch is moved down, the processor 190 changes state. A light bar on a side wall of the vaporizer housing 54 may be used to indicate both the mode and relative temperature of the oven. By non-limiting example, a first downward movement and release of the sliding switch may turn the vaporizer on and cause the light bar to flash a first, lower light of the light bar to indicate a first mode and first temperature setting for the oven. The light bar may then start to increase the quantity of the light bar that is lighted up from none of the light bar being lit to a greater amount of the light bar being lit as the temperature rises, until the light bar is lit to the first, lower light portion of the light bar is lit. A second downward movement and release of the sliding switch may cause the light bar to flash a second, medium light of the light bar to indicate the second mode and second temperature setting for the oven, and the light bar may continue in its slow increase in the light bar lighted length increasing with temperature increase until the higher temperature is reached. Subsequent downward movements and release of the sliding switch may further cause additional flashes, changes to the temperature settings for the processor and oven, and further increase in the light bar lighted length as the temperature increases until the maximum temperature setting has been reached and the light bar is fully lit. After the maximum temperature setting has been reached by downward movements and releases of the sliding switch, an additional downward movement and release of the sliding switch may cause the processor to turn the vaporizer off and allow the user to start the process of turning the vaporizer on and selecting a desired mode again.

A slidable switch positioned on the housing slidable between a first switch position and at least a second switch position, wherein the slidable switch is operably coupled to the dual mouthpiece such that sliding the slidable switch to the first switch position moves the dual mouthpiece to the first mouthpiece position and sliding the slidable switch to the second switch position moves the dual mouthpiece to the at least second mouthpiece position. The dual mouthpiece may be adjustable between the first mouthpiece position, the second mouthpiece position, and at least a third mouthpiece position wherein neither the first mouthpiece nor the second mouthpiece extend from the first end of the housing, and wherein the slidable switch may be slidable between the first switch position, the second switch position, and at least a third switch position that retracts both the first and the second mouthpiece from extending from the first end of the housing. A magnetic cover removably coupled to the second end of the housing and positioned such that removal of the magnetic cover allows direct access to the oven of the heating assembly. A power button and one or more light emitting diodes (LEDs), wherein the heating assembly is operably coupled to the power button and adjustable between a plurality of temperature settings.

In a non-limiting embodiment with specific reference to FIGS. 40-50, an electronic cigarette 90. Aspects of each of the previous electronic cigarettes disclosed herein may be implemented in the embodiment illustrated in FIGS. 40-50 unless expressly stated otherwise. Specifically, with respect to FIGS. 40-45G, particular aspects of the oven lid 92 and its relation to the oven 94 and the cigarette housing surrounding the opening to the oven 94. The oven lid 92 is pivotally attached to the cigarette housing 91. Sides 96 of the opening to the oven 94 are positioned at an angle, flaring outward in relation to the sides 98 of the oven so that the sides 96 of the opening are not parallel to the oven sides. The angled sides 96 and the front edge 102 of the oven opening form an oven lid seat 100. The oven lid 92 is pivotable from an open position (FIG. 41) to a closed position (FIGS. 40 and 42).

Magnets 106 in one or both sides 104 of the oven lid 92 and corresponding magnets 108 hold the oven lid 92 closed when the oven lid 92 is moved to its closed position. Because the sides 104 of the oven lid 92 and the sides 96 of the oven lid seat 100 are mated at an angle in relation to the walls 98 of the oven 94, when the oven lid 92 is moved up out of its seat 100, the respective magnets 106, 108 begin to repel each other and push the oven lid 92 toward its open position and maintain the oven lid 92 in an open position until a user forcibly presses against the open oven lid 92 in a direction to close the oven lid 92 back toward the oven seat 100 and the closed position. When the force pressing the oven lid 92 closed overcomes the magnetic repulsion caused by the magnets 106, 108 and the oven lid 92 gets close enough to the oven lid seat 100, the magnets 106, 108 again begin to attract each other pulling the oven lid 92 closed against the oven lid seat 100. Particular embodiments may position the particular oven opening sides 96 at various angles with respect to a top surface 110 of the cigarette housing 91. Operable angles include 40 to 80 degrees, although angles of between 60 to 75 degrees provide a strong attraction and repulsion. Rare earth magnets work well, although any permanent magnet may be used.

The cigarette housing 91 includes, adjacent to the oven opening, first 112 and second 114 pivot receivers for the first 116 and second 118 pivots of the oven lid 92. A first pivot receiver 112 is enclosed (FIG. 40) and a second pivot receiver 114 includes an opening slot at the top surface 110 of the cigarette housing to allow the second pivot 118 of the oven lid 92 to slide into the pivot receiver 114 through the top surface 110. The first pivot 116 of the embodiment shown in FIGS. 45A-45G is round and the second pivot 118 is rounded with two flattened sides to fit into the opening slot on the top surface 110 of the cigarette housing in only one orientation. To assemble the oven lid 92 on the cigarette housing 91, the first pivot 116 is inserted into the first pivot receiver 112. The oven lid 92 is pivoted so that the sides of the second pivot 118 are aligned with the opening slot at the top surface 110 of the cigarette housing 91 (see orientation in FIG. 44). The second pivot 118 is then slid through the opening slot until the second pivot 118 is seated in the second pivot receiver 114 (FIG. 43). Then the oven lid 92 is moved by magnetic force either toward or away the oven lid seat 100. Because the orientation of the second pivot 118 needed to cause the oven lid 92 to mount to the cigarette housing 91 is at an angle that is not a rest position for the oven lid 92 but instead is within the natural magnetic force of the magnets 106, 108, the oven lid 92 can only be moved by intentionally forcing the lid to the position to re-align the sides of the second pivot 118 with the sides of the opening slot to remove the oven lid 92. Otherwise, the oven lid 92 is automatically pushed past that specific angular point, either toward the open or the closed position, by the magnetic force of the magnets 106, 108. When the oven lid 92 is in the closed position, the oven shield 120 is facing the oven 94. The particular angle at which the oven lid 92 second pivot 118 is aligned with the sides of the opening slot is not critical to the operation provided it occurs within the magnetic force of the magnets 106, 108. However, an oven lid 92 angle of between 30-60 degrees relative to the top surface 110 of the housing 91, and in particular embodiments 40-50 degrees is considered most desirable.

One or more embodiments of an electronic cigarette 90 further comprise a slidable switch 130 coupled to the housing 92 and slidable between a first switch position (FIGS. 47 and 49) and at least a second switch position (FIGS. 48 and 50), and is biased away from the second position back to the first position such that the switch 130 automatically reverts to the first switch position after being moved to the second switch position. Sliding the slidable switch to the second switch position may turn the electronic cigarette on or off or toggle a temperature setting of the heating assembly. More particularly, an electronic cigarette 90 may comprise a first magnet 131 positioned on the housing 91, and a second magnet 132 positioned on the slidable switch 130 to interface with the first magnet as the switch 130 slides. A sensor 134, such as a Hall-Effect sensor, magnetic sensor, optical sensor or mechanical sensor, senses movement of the slidable switch 130 into the second position and triggers a change in the processor state for the electronic cigarette 90. In a particular embodiment, a Hall-Effect sensor 134 is placed on the housing 91 and an additional magnet 133 is placed on the sliding switch 130 to trigger the Hall-Effect sensor 134. The state change may, for example, turn the electronic cigarette on or off or toggle the temperature setting of the heating assembly. Although the magnets 131, 132 in the embodiment illustrated in FIGS. 46-50 are shown attracting the switch 131 to the first position, they could equivalently be configured to repel each other away from the second position to move the sliding switch 131 into the first position. Use of magnetic force to move the switch to the first position either way is equally desirable.

A temperature sensor 136 may be positioned to extend into the oven 94 of the electronic cigarette 90 (FIGS. 47-48). In particular embodiments where a substance pod (not shown) is used, the substance pod, containing the substance to be vaporized in the oven 94, may be configured to be puncturable, either through a scored region on the substance pod or because the substance pod shell is puncturable by the temperature sensor 136, so that when the substance pod is placed in the oven and the lid is closed on the oven, the temperature sensor 136 is positioned at least partially within the substance pod shell and the substance within the shell that is being vaporized in the oven.
