Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application is based on and derives the benefit of the filing date of U.S. Provisional Application No. 62/835,416 filed on Apr. 17, 2019 entitled “VAPORIZER POD SYSTEMS AND METHODS,” the contents of which are incorporated herein by reference in their entireties. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to vaporizers and in particular to dual airflow vaporizer pods. 
     BACKGROUND OF THE INVENTION 
     Vaporizers are typically used to aerosolize liquids or volatile substances contained in solid or semisolid substances. Vaporizers designed for plant-based materials, extracts, and/or oils have recently grown in popularity. During operation, these devices typically require a user to draw air into a chamber of the device where the plant material, extract, and/or oil is heated. This air is then drawn into the user&#39;s mouth along with the aerosolized liquids or volatile substances generated by heating the plant material, extract, and/or oil. In such systems, air flow may be hindered or prevented by partial or complete solidification of the plant material, extract, and/or oil. Additionally, air drawn into the user&#39;s mouth may be hot, negatively affect the flavor of the inhaled vapor or burning the user&#39;s mouth. Accordingly, new and improved vaporizers are needed.

     DETAILED DESCRIPTION OF THE INVENTION 
     The following description is of various embodiments only, and is not intended to limit the scope, applicability or configuration of the present disclosure in any way. Rather, the following description is intended to provide a convenient illustration for implementing various embodiments including the best mode. As will become apparent, various changes may be made in the function and arrangement of the elements described in these embodiments without departing from the scope of the present disclosure or appended claims. 
     The detailed description of exemplary embodiments herein makes reference to the accompanying drawings and pictures, which show various embodiments by way of illustration. While these various embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, it should be understood that other embodiments may be realized and that logical and/or functional changes may be made without departing from the spirit and scope of the disclosure. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation. Any reference to singular includes plural embodiments, and any reference to more than one component may include a singular embodiment. 
     Vaporizer systems and devices are provided. In the detailed description herein, references to “an exemplary embodiment.” “various embodiments,” “one embodiment,” “an embodiment,” “an example embodiment,” etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described. After reading the description, it will be apparent to one skilled in the relevant art(s) how to implement the disclosure in alternative embodiments. 
     For the sake of brevity, conventional vaporizers and vaporizer components may not be described in detail herein. Furthermore, the connecting lines shown in various figures contained herein are intended to represent exemplary functional relationships and/or physical or communicative couplings between various elements. It should be noted that many alternative or additional functional relationships or physical or communicative connections may be present in a practical vaporizer system. 
     In various embodiments, a vaporizer pod is disclosed herein. The vaporizer pod may be configured to heat tobacco or other plant materials, extracts, or oils at a temperature such that certain volatile substances contained in the tobacco or other plant material, extract, and/or oil are vaporized without combustion. In various embodiments, the vaporizer pod may be compatible for use in a portable vaporizer, vaporizer pen, desktop vaporizer, or any other suitable type of vaporizer. 
     The vaporizer pod disclosed herein may be configured to direct two, separated air flows simultaneously into a user&#39;s mouth during operation of a vaporizer coupled to the vaporizer pod. A first air flow may communicate ambient air from outside the vaporizer pod, to, near, and/or through a heating element, and subsequently to, near, and/or into a user&#39;s mouth. The heating element ray be in contact with a plant material, extract, and/or oil disposed within the vaporizer pod. Application of heat by the heating element may cause evaporation, sublimation, volatilization, or other atomization of all or a portion of the plant material, extract, and/or oil such that it is carried by the heated first air flow to, near, and/or into a user&#39;s mouth. A second air flow may communicate ambient air from outside the vaporizer pod, through the vaporizer pod, and to, near, and/or into the user&#39;s mouth. 
     In various embodiments, the second air flow may commingle with the first air flow near or inside the user&#39;s mouth. However, the second air flow may commingle with the first air flow inside the vaporizer pod, for example, after the first air flow has been heated by the heating element. In various embodiments, the temperature of the second air flow is lower than the temperature of the heated first air flow, and commingling of the air flow lowers the temperature of a vapor inside and/or entering the user&#39;s mouth. In various embodiments, vapor comprising a lower temperature has an improved taste relative to vapor comprising a higher temperature. In various embodiments, lower temperature of the vapor prevents burning of, and/or discomfort to, the user&#39;s lips, tongue, gums, teeth, cheeks, and/or mouth. 
     In various embodiments, simultaneous communication of two, separated air flows to the user&#39;s mouth allows the user to take a larger volume of vapor in a single drag. Larger drag volume may improve the taste of the vapor relative to smaller drag volume. Larger drag volume may allow the vapor to contact more portions of the user&#39;s lips, tongue, cheeks, and/or mouth than smaller drag volume. Larger drag volume may allow the user inhale vapor more deeply than smaller drag volume. For example, larger drag volume may allow the user, at his or her option, to take a direct lung inhale (for example, inhaling vapor directly into the lungs) and/or to take a mouth to lung inhale (for example, sucking vapor into the mouth and subsequently opening the mouth as the vapor and ambient air are inhaled). In various embodiments, optional election of mouth to lung inhalation or direct lung inhalation may be beneficial for users habituated to cigarettes or cigars, for new vaporizer users, and/or for individuals with impaired lung capacity or hyperinflation of the lungs. 
     Certain plant materials, extracts, and/or oils suitable for use in vaporizer pods may be thick, viscous, solid and/or semisolid at ambient temperature. After such plant materials, extracts, and/or oils are disposed in a vaporizer pod, they may collect at or near a heating element and, because they are thick, viscous, solid, and/or semisolid, may restrict or prevent communication of air through the vaporizer pod and/or into the user&#39;s mouth. The vaporizer pod disclosed herein may continue to communicate air through the vaporizer pod and/or into the user&#39;s mouth via the second air flow, even when plant materials, extracts, and/or oils disposed within the vaporizer pod become thick, viscous, solid, and/or semisolid. 
     In various embodiments, the vaporizer pod and/or the vaporizer to which it is coupled comprises a pressure sensor. Communication of the second air flow through the vaporizer pod (for example, when a user takes a drag from the vaporizer pod) may be detected by the pressure sensor. The pressure sensor may send a signal to a processor and/or a controller that causes a heating element of the vaporizer pod to heat up. An increase in temperature of the heating element may cause the plant materials, extracts, and/or oils—which may be obstructing communication of the first air flow to heat and become more liquid and/or less viscous. In this way, heating of plant materials, extracts, and/or oils disposed within the vaporizer pod may be activated through ordinary operation of the vaporizer pod, namely, when a user takes a drag from the vaporizer pod. 
     In various embodiments and with reference to  FIGS.  1 - 10   , a vaporizer pod  100  comprises a housing  110 . Housing  110  may be configured to receive plant materials, extracts, and/or oils into a reservoir  111  defined by housing  110 . In various embodiments, housing  110  comprises a generally prismatic shape. However, in various embodiments, the housing may comprise a cuboidal shape, spherical shape, conical shape, pyramidal shape, or any other shape suitable for defining a reservoir. In various embodiments, housing  110  comprises a shape complementary to the shape of a vaporizer, such that vaporizer pod  100  may be disposed at least partially in, or otherwise coupled to, the vaporizer. 
     Housing  110  may comprise component parts. For example, in various embodiments, housing  110  comprises a mouthpiece  112 , an upper portion  119 , and/or one or more base portions ( 114 ,  115 ). However, in various embodiments, the housing is integral. 
     Mouthpiece  112  may be coupled to, and/or comprise a portion of, housing  110 . In various embodiments, mouthpiece  112  comprises a contact portion that is configured to be in contact with a user&#39;s mouth. A central channel outlet  144  may be disposed on, and defined by, mouthpiece  112 . An atomizer channel outlet  137  may be disposed on, and defined by, mouthpiece  112 . Central channel outlet  144  and atomizer channel outlet  137  may be disposed in close proximity to one another on mouthpiece  112 , such that central channel outlet  144  and atomizer channel outlet  137  are configured to be placed in a user&#39;s mouth simultaneously. In various embodiments, for example, when the second air flow and the first air flow are commingled inside the vaporizer pod the central channel outlet and the atomizer channel outlet may comprise the same aperture defined in the mouthpiece. In various embodiments, central channel outlet  144  and atomizer channel outlet  137  are disposed in a top surface of mouthpiece  112 . However, central channel outlet  144  and atomizer channel outlet  137  may be disposed on any suitable surface or portion of housing  110 . 
     In various embodiments, vaporizer pod  100  is configured to communicate a central air flow  141  (e.g., a second air flow) from a central channel inlet  142 , through a central channel  140 , to and through central channel outlet  144 , and out of vaporizer pod  100 . Central channel inlet  142  may be disposed on, and defined by, housing  110 . In various embodiments, central channel inlet  142  is disposed on, and defined by, a second base portion  115  of housing  110 . Central channel inlet  142  may be disposed in a bottom surface of housing  110 . However, central channel inlet  142  may be disposed on any suitable portion of housing  110 . 
     Housing  110  and/or a base portion ( 114 ,  115 ) thereof may define a portion of central channel  140 . Central channel  140  may comprise a channel, tube, hollow cylinder, hose, or other conduit configured to communicate ambient air through vaporizer pod  100 , as generally illustrated in the accompanying figures as central air flow  141 , and out of vaporizer pod  100  via central channel outlet  144 . In various embodiments, ambient air communicated via central air flow  141  does not contact any portion of vaporizer pod  100  other than housing  110  and/or central channel  140  defined thereby. Stated differently, the composition and other characteristics (for example, temperature, humidity, etc.) of ambient air entering central channel inlet  142  may be generally unchanged as it travels rough central channel  140  and exits central channel outlet  144 . In various embodiments, however, ambient air may be commingled with heated air and/or vapor from an atomizer air flow (hereinafter described) just before entering a user&#39;s mouth. 
     In various embodiments, vaporizer pod  100  is configured to communicate an atomizer air flow  131  (e.g., a first air flow) from an atomizer channel inlet  136 , through an atomizer channel  130 , to and through atomizer channel outlet  137 , and out of vaporizer pod  100 . Atomizer channel inlet  136  may be disposed on, and defined by, housing  110 . In various embodiments, atomizer channel inlet  136  is disposed on, and defined by, an upper portion  119  of housing  110 . Atomizer channel inlet  136  may be disposed in a side surface of upper portion  119 . However, atomizer channel inlet  136  may be disposed on any suitable portion of housing  110 , upper portion  119 , and/or mouthpiece  112 . 
     Housing  110  and/or a base portion ( 114 ,  115 ) may define some or all of atomizer channel  130 . Atomizer channel  130  may comprise a channel, tube, hollow cylinder, hose, or other conduit configured to communicate ambient air through vaporizer pod  100 , as generally illustrated in the accompanying figures as atomizer air flow  131 , and out of vaporizer pod  100  via atomizer channel outlet  137 . 
     In various embodiments, at least a portion of atomizer channel  130  is defined by a column  132 . Column  132  may be at least partially disposed in reservoir  111  and may be configured to at leak partially segregate reservoir  111  from atomizer channel  130 . In various embodiments, column  132  is configured to facilitate contact between ambient air communicated via atomizer air flow  131  and plant materials, extracts, and/or oils disposed generally within vaporizer pod  100 . Column  132  may further be configured to receive a heat conductor  135  and facilitate contact between heat conductor  135  and plant materials, extracts, or oils disposed generally within vaporizer pod  100 . Column  132  may generally comprise a hollow cylindrical shape. However, column  132  may comprise any shape suitable for use in vaporizer pod  100 . 
     Heat conductor  135  may be disposed at least partially within column  132 . In various embodiments, heat conductor comprises a generally cylindrical, tubular, or helical shape, such that fluid (for example, air, vapor, liquids, and the like) may generally pass through heat conductor  135  from a first end to a second end. Heat conductor  135  may be disposed vertically relative to column  132  and/or vaporizer pod  100 . Stated differently, heat conductor  135  may comprise a central axis generally parallel to, and/or shared with, a central axis of column  132 . In various embodiments, heat conductor comprises a material that is sufficiently porous such that fluid (for example, air, vapor, liquids, and the like) may generally pass through heat conductor  135  from a first end to a second end. However, heat conductor  135  may comprise any shape or material suitable for use in vaporizer pod  100 . 
     In various embodiments, ambient air drawn through atomizer channel inlet  136  enters a portion of housing  110  that is segregated from reservoir  111 . In various embodiments, as ambient air is communicated along atomizer air flow  131 , it is brought into contact with and enters a bottom end of column  132  and/or heat conductor  135 . As the ambient air is communicated through and/or brought into contact with heat conductor  135 , it may be commingled with all or a portion of the plant material, extract, and/or oil that has evaporated, sublimated, volatilized, and/or otherwise atomized. A vapor that results from such commingling is then communicated through a top end of heat conductor  135  and/or column  132 , and is further communicated through atomizer channel outlet  137 . 
     In various embodiments, column  132  comprises a first fluid port  133 . First fluid port  133  may comprise an aperture, opening, slot, hole, or the like disposed on and defined by a sidewall of column  132 . First fluid port  133  may be configured to interface with one or more portions of housing  110  (for example, base portions  114 ,  115 ) so as to direct the communication of ambient air into a bottom end of heat conductor  135 . 
     In various embodiments, column  132  comprises one or more second fluid ports  134 . Second fluid port  134  may comprise an aperture, opening, slot, hole, or the like disposed on and defined by a sidewall of column  132 . In various embodiments, second fluid port  134  is disposed above first fluid port  133 . In various embodiments, second fluid port  134  is disposed above first base portion  114 . Second fluid port  134  may be configured to allow communication of plant materials, extracts, and/or oils from reservoir  111 , into column  132 , and into contact with heat conductor  135 . 
     Heat conductor  135  may be configured to receive an electrical current from a power source, such as a battery, electric socket, electric generator, or the like.

However, heat conductor  135  may comprise any mineral, metal, alloy, ceramic, composite, or other material suitable for use in vaporizer pod  100 . In various embodiments, heat conductor  135  may be selected based on physical properties of vaporizer pod  100 . For example, heat conductor  135  may comprise a material having a maximum temperature threshold (based on the voltage applied to it by a power source) below a melting temperature of one or more portions of vaporizer pod  100 . 
     In various embodiments, heat conductor  135  is disposed vertically within column  132  and/or vaporizer pod  100 . Stated differently, heat conductor  135  may be disposed with a first end below a second end, and may be configured to communicate a fluid in an upward direction relative to vaporizer pod  100 . In various embodiments, vertical disposition and/or orientation may allow heat conductor  135  to be larger and/or longer than would be possible with a horizontal disposition and/or orientation. A larger and/or longer heat conductor may improve and/or increase evaporation, sublimation, volatilization, and/or atomization of plant material, extract, and/or oil. A larger and/or longer heat conductor may improve the flavor of vapor produced by the vaporizer. A larger and/or longer heat conductor may allow the vaporizer to operate at a lower relative temperature.

     In various embodiments, vaporizer pod  100  further comprises a fill aperture  125  configured to allow a user to fill reservoir  111  with plant materials, extracts, and/or oils. Fill aperture  125  may be disposed on, and defined by, housing  110 . In various embodiments, fill aperture  125  is disposed on, and defined by, a side wall of upper portion  119 . Fill aperture  125  may comprise a circular, ovoid, square, or any other suitable shape. In various embodiments, fill aperture  125  comprises a shape complimentary to a plug portion  124  of fill plug  120  that is configured to be force fit into fill aperture  125 . 
     Fill plug  120  may further comprise an anchor  122  configured to secure a portion of fill plug  120  to housing  110 , while allowing plug portion  124  to be optionally remove from, and replaced within till aperture  125 . In various embodiments, fill plug  120  is configured to seal or otherwise prevent fluid from exiting reservoir  111  through fill aperture  125 .
