Definitions
- aspects of the present invention relate to portable electronic vaporizing devices for use with vaporizable products.
- vaporizers are common place and are generally utilized for the purpose of aroma and/or inhalation therapy.
- vaporizers heat a substance, herbs for example, such as tobacco, cannabis , lavender, chamomile, and many other types of plant material.
- the vaporizer may work by heating the substance through the use of direct heat or the use of hot air.
- the second is thermal radiation in which light is used to heat the substance.
- the third is convection where hot air is passed over the substance.
- vapors extracted from substances such as vegetable materials are mainly aroma therapeutic (inactive fragrance) and do not usually contain the active ingredients of the substance. Without the active ingredients being present, there is no physiological reaction.
- active ingredients will be increasingly included in the vapor given off during heating. Usually, aromatic vapors have already been released and are not always present at the higher heat levels. With some substances, such as cannabis , active ingredients appear at different levels of heat.
- vaporizers use a cooling down process that allows water moisture to be included in the vapor produced. These vaporizers enable the user to inhale a cool moist vapor that is relatively less harsh and irritating. Vaporizers are often preferred over traditional methods of heating or smoking substances due to the reduction of harsh side effects. Some of these side effects include inhalation of tar, carbon monoxide, and other carcinogens either directly or from second hand smoke. With many states imposing smoking bans in public areas, vaporizers have become popular substitutes.
- aspects of the invention are directed to a portable electronic vaporizing device comprising:
- FIG. 1 shows embodiments of a portable electronic vaporizing device comprising a base, atomizer and mouthpiece;
- FIG. 2 is an exploded view of the device of FIG. 1 ;

- the one or more second container outlets 306 are located radially externally to the first container inlet 305 , and/or are positioned in an arrangement circumferentially surrounding the first container inlet 305 .
- the second container outlets 306 may also be located towards a top end of the atomizer and/or container.
- the apertures and/or outlets 309 for exhausting gas from the atomizer are located below the first container inlet and/or second container outlet, towards a lower end of the atomizer.
- a container comprising a bowl 7 is positioned on top of the heating element 8 , and may be made of a highly thermally conductive material, which can include ceramic, quartz, or metals, allowing efficient heat transfer.
- the heating element 8 and the bowl 7 are secured and insulated by the bottom insulating element 9 and top insulating element 311 respectively, these two elements firmly locating the heating element 8 and bowl 7 within the atomizer. These two elements are made with low thermally conductive, yet high heat withstanding, material so that minimal heat is lost from the heating element and bowl.
- the top insulating element comprises an outer annular ring comprising sleeve 6 , made of an insulating material, like silicone or plastic.
- the sleeve 6 fastens to the housing 10 and makes an airtight seal while the inner annular ring 5 insulates and positions the bowl 7 .
- the sleeve 6 may also protect the user from heat and serves as a grip for screwing and unscrewing the atomizer.
- the bowl 7 may become dirty. Because the top insulating element comprising in inner annular ring 5 and sleeve ( 6 ) are removable, the bowl can be taken out and easily cleaned.
- the sleeve and top insulating element are assembled on the atomizer housing the bowl is held in place and a sealed airpath is formed. Air may enter the top of the bowl through a carb cap 17 .
- the carb cap 17 may be capable of directing high velocity air to the bottom of the bowl, where the material is vaporized. Air then exits the top of the bowl as vapor through the second outlets which are apertures in the inner annular ring ( 5 ) above the bowl. These slots/apertures could also be cut into the top of the bowl.
- FIG. 6B shows a cross sectional view of the assembled atomizer with the carb cap and illustrates the airflow through the atomizer, entering through the carb cap and exiting out of the bottom of the atomizer.
- material that leaks out of the bowl 7 can seep down into the bottom of the atomizer near the connection point. Accordingly, it may be important for this area to be sealed so that the leaking material does not inhibit the passing of the current from power source to heating element.
- This seal is provided by the electrode insulator 11 which holds the electrode 12 .
- the electrode insulator secures and holds separately the electrode from the housing.
- One lead wire of heating element 8 can be held between the insulator and the housing 10 , the other lead wire can be held between the insulator and the electrode, therefore a current path in and out of the heating element can be created.
- the electrode insulator can press the wires into these grooves and make a water and airtight seal against the housing and electrode which may prevents leaking.
- material may also leak out of the bottom of the atomizer through the air cuts in the housing 10 . Accordingly, it may be important that this material does not reach the connection point on the atomizer or the power source.
- a rib 14 running around the bottom of the atomizer housing 10 can create a seal. This seal can create a separation between the air holes and connection point and may prevent any material from reaching the electrical connection points on the atomizer or base.
- the bowl 7 , heating element 8 and inner annular ring 5 may interact with sticky material during use, there is a chance for them to become stuck together.
- the heating element could be twisted and could lead to subsequent breaking of its lead wires.
- features may be included in the atomizer housing 10 and inner annular ring 5 .
- slots in the atomizer housing 10 may line up with embossed features 16 in the inner annular ring 5 , so that the two lock together and cannot be twisted independently. This protects the heating element from damage when tightening or loosening the atomizer from the base.
- the bowl itself can include a rib 15 around its bottom face, which is the face that interacts with the heating element.
- This rib may have three functions, it can positions the bowl, cover the heating element, and/or minimize heat loss, and it can shroud the heating element from debris.
- the debris could be water or liquid material that leaks down into the heating elements environment. Since the heating element may operate at a high temperature, a substance of room temperature contacting the heating element can result in significant thermal shock which could damage or permanently break the heating element.
- the rib on the bottom of the bowl blocks debris by creating a protective wall around the heating element.
- the mouthpiece 4 is removably attachable to the base 2 .

Abstract
The present invention relates to a portable electronic vaporizing device for use in the inhalation of vaporizable substances.
Description
- This application is a continuation of U.S. patent application Ser. No. 16/662,631, filed Oct. 24, 2019, which is a continuation of U.S. patent application Ser. No. 16/373,170, filed on Apr. 2, 2019, which claims the benefit of priority from U.S. Provisional Patent Application 62/792,202 filed on Jan. 14, 2019 and claims the benefit of International Application PCT/US19/13501 filed on Jan. 14, 2019, the disclosures of all of which are hereby incorporated herein by reference in their entireties.
- Aspects of the present invention relate to portable electronic vaporizing devices for use with vaporizable products.
- Electronic vaporizers are common place and are generally utilized for the purpose of aroma and/or inhalation therapy. In this regard, vaporizers heat a substance, herbs for example, such as tobacco, cannabis, lavender, chamomile, and many other types of plant material. The vaporizer may work by heating the substance through the use of direct heat or the use of hot air. There are three common ways of heating the substance. The first is thermal conduction where the substance is set directly on a heating element such as a ceramic or metal plate. The second is thermal radiation in which light is used to heat the substance. The third is convection where hot air is passed over the substance.
- At lower levels of heat, vapors extracted from substances such as vegetable materials are mainly aroma therapeutic (inactive fragrance) and do not usually contain the active ingredients of the substance. Without the active ingredients being present, there is no physiological reaction. At higher levels of heat, active ingredients will be increasingly included in the vapor given off during heating. Usually, aromatic vapors have already been released and are not always present at the higher heat levels. With some substances, such as cannabis, active ingredients appear at different levels of heat.
- After the substance is heated a mist or vapor containing some aspect of the substance is released and either enjoyed as an aromatic or inhaled to obtain a physiological reaction. The warm air containing the substance product can be harsh on the throat and bronchial tubes. Accordingly, some vaporizers use a cooling down process that allows water moisture to be included in the vapor produced. These vaporizers enable the user to inhale a cool moist vapor that is relatively less harsh and irritating. Vaporizers are often preferred over traditional methods of heating or smoking substances due to the reduction of harsh side effects. Some of these side effects include inhalation of tar, carbon monoxide, and other carcinogens either directly or from second hand smoke. With many states imposing smoking bans in public areas, vaporizers have become popular substitutes.
- Accordingly, there is a need for improved vaporizers that provide an enhanced vaporizing experience, including vaporizers with improved quality of the vapor produced for inhalation and improved ease of use.
- Aspects of the invention are directed to a portable electronic vaporizing device comprising:
-
- a base having comprising a gas flow path conduit therein, the gas flow path conduit comprising a conduit inlet and a conduit outlet;
- a mouthpiece that is removably attachable to the base, the mouthpiece comprising:
- a mouthpiece housing comprising one or more mouthpiece walls at least partly defining a mouthpiece internal flow path through the mouthpiece housing;
- an inhalation outlet formed in a region of the one or more mouthpiece walls; and
- at least one mouthpiece inlet capable of being placed in communication with the conduit outlet of the base upon attachment of the mouthpiece to the base, to receive a flow of gas into the mouthpiece from the base; and
- an atomizer that is removably attachable to the base, the atomizer comprising:
- an atomizer inlet configured to receive a flow of gas into the atomizer;
- an atomizer housing comprising one or more atomizer housing walls that at least partially define an atomizer internal flow path therein,
- a container within the atomizer housing that is capable of holding a vaporizable product,
- a heating element capable of heating the vaporizable product held in the container,
- a first container inlet capable of introducing gas into the container to entrain vaporizable product;
- one or more second container outlets capable of flowing the gas having the vaporizable product entrained therein into atomizer internal flow path;
- one or more atomizer outlets capable of receiving the flows of gas from the atomizer internal flow path, and providing the flow of gas to the conduit inlet of the base,
- wherein the flow of gas having the vaporizable product entrained therein flows from the atomizer internal flow path and through the gas flow conduit inlet of the base to the mouthpiece inlet, and along the mouthpiece internal flow path to the inhalation outlet.

Examples of such substances can include herbs, such as tobacco, cannabis, lavender, chamomile, and other types of plant material. In one embodiment, a vaporizable substance can comprise a cannabinoid, such as for example one or more of cannabadiol (a generally non-psychoactive therapeutic substance) and tetrahydrocannabinol (THC) (a psychoactive therapeutic substance). The vaporizable substance may in some embodiments be in the form of an oil and/or wax product comprising the vaporizable substance, e.g., as extracted from plant material containing the substance, and may optionally be provided in combination with carriers or other additives.
- Referring to
FIG. 1 , an embodiment of a portable electronic vaporizing device 1 is shown according to aspects of the disclosure herein. The portable electronic device 1 comprises abase 2, andatomizer 3 and amouthpiece 4. Theatomizer 3 is configured to receive a vaporizable product therein and to heat the vaporizable product to form a vapor therefrom. Themouthpiece 4 comprises an outlet where a user can inhale the vapor produced by the atomizer, optionally with water or other substances entrained therein. Thebase 2 provides a gas flow connection between theatomizer 3 andmouthpiece 4, to deliver the vaporized product from theatomizer 3 to themouthpiece 4 for delivery to the use via inhalation thereof. Thebase 2 can also comprise a housing for one or more components for powering and/or controlling the device 1. For example, the base may contain compartments therein for storing a power source, such as a battery, for powering elements of the device 1 such as a heating element used in theatomizer 3. In a case where the device is powered by a rechargeable battery, such as a lithium ion battery, thebase 2 may also comprise a charging port connectable to a battery charger (not shown). The base may also have compartment doors to allow access to a battery or other components held within the housing. Thebase 2 may also house further control circuitry for controlling the device, such as to provide predetermined heating cycles or heating programs, and may also allow for user interaction with the device via control buttons and/or control interface, a display and/or lights to signal to the user, and/or other control and operation features. - Referring to
FIG. 2 , an embodiment of the device 1 is shown in exploded view, with themouthpiece 4 andatomizer 3 removed from thebase 2. In one embodiment, themouthpiece 4 is removably attachable to thebase 2, for example so as to allow a user to readily remove the mouthpiece for cleaning and/or replacement, as is described in further detail herein. In yet another embodiment, the atomizer may be removably attachable to the base, for example so as to allow a user to replace theatomizer 3 when no longer serviceable, for cleaning of the atomizer, and/or to more readily allow access to a container (e.g. bowl) where a vaporizable product may be loaded into theatomizer 3. In one embodiment, both theatomizer 3 and themouthpiece 4 may be removably attachable to thebase 2. In yet another version, theatomizer 3 may be independently removable from thebase 2. That is, theatomizer 3 may be configured to be removably attached to the base such that it can be removed therefrom, without requiring that themouthpiece 2 be removed beforehand. Referring toFIG. 2 it can be seen that theatomizer 3 itself is external to themouthpiece 4, and its connection to thebase 2 is also at a position that is outside themouthpiece 4, such that theatomizer 3 can be removed from thebase 2 while the mouthpiece is kept attached to the base. Similarly, according to the embodiment as shown, themouthpiece 4 can be removed from thebase 2 independently of theatomizer 3, as themouthpiece 4 and its connection to the base are external to the atomizer, and so themouthpiece 4 can be removed from thebase 2 without requiring removal of theatomizer 3. Furthermore, in the embodiment as shown inFIG. 2 , theatomizer 3 can be loaded with vaporizable product without requiring removal of themouthpiece 4, and without requiring passing of the vaporizable product through a portion of the mouthpiece, as the atomizer can be accessed separately from the mouthpiece. - Referring to
FIG. 3 , an embodiment of a gas flow path through the portable electronic device 1 is shown. In one embodiment, a flow of ambient air is received in theatomizer 3, where the ambient air is entrained with vaporizable product that is vaporized in the atomizer via a heating element. The gas comprising the ambient air and vaporizable product flows from theatomizer 3 to a portion of thebase 2 having a gas flow conduit therein, and which provide a sealed gas flow connection between theatomizer 3 andmouthpiece 4. The gas received into themouthpiece 4, where it is directed to an inhalation outlet of the mouthpiece, where the gas comprising the vaporizable product can be inhaled by the user. In one embodiment, water is provided a region of themouthpiece 4 such that water is entrained with the gas passing through the mouthpiece, thereby providing a more pleasant inhalation experience to the user. An embodiment of an overall flow path of gas through the device 1 is depicted via dashed lines inFIG. 3 . - Referring to
FIGS. 4A-4D , embodiments of thebase 2, and mechanism of attachment of thebase 2 to one or more of theatomizer 3 andmouthpiece 4 are described in more detail. As shown inFIGS. 4A-4D , thebase 2 comprises a gasflow path conduit 200 therein, the gasflow path conduit 200 comprising aconduit inlet 201 a and aconduit outlet 201 b, an embodiment of which may also be viewed with respect toFIG. 5 . Theconduit inlet 201 a receives gas exhausted from theatomizer 3, and provides a flow of gas to themouthpiece 4. In one embodiment, one or more airtight seals are formed between thebase 2 and/or theatomizer 3 andmouthpiece 4, so as to create an airtight gas flow path between from the atomizer, through the gasflow path conduit 200 in thebase 2, and to themouthpiece 4. In the embodiment as shown, thegas flow conduit 200 in the base separates an atomizer internal gas flow path from a mouthpiece internal flow path. - According to one embodiment, the
atomizer 3 and/ormouthpiece 4 are removably attachable to thebase 2 via afastening feature 202 that allows for repeated removal and re-insertion of theatomizer 3 and/ormouthpiece 4 into the base.

FIGS. 4A-4D , thebase 2 comprises first and second recessedregions base 2 that are configured to receive at least a portion of theatomizer 3 and mouthpiece therein. For example, the base can comprise a first recessedregion 203 a configured to receive at least a portion of theatomizer 3 therein, and a second recessedregion 203 b configured to receive at least a portion of themouthpiece 4 therein. In one embodiment, thefastening feature 202 is provided as part of the base, and can comprise one or moreairtight sealing members member 204 a provided in the first recessed region to retain the atomizer therein, and/or a second airtight sealingmember 204 b provided in the second recessed region to retain themouthpiece 4 therein.

For example, themouthpiece 4 may comprise asnap region 401 that is configured to be received by the second recessed region of the base, and that comprising afastening feature 202 thereon to retain the step region in the base, as is described in more detail hereinbelow. In one embodiment, the fastening feature that removably retains one or more of the atomizer and/or mouthpiece in their respective recessed region is also capable of providing an airtight seal between the base and atomizer and/or mouthpiece. In another embodiment, the fastening feature comprises a structural element that is separate from and/or provided in addition to an airtight sealing member. For example, in one embodiment, the base and atomizer and/or mouthpiece may be fastened together by a fastening feature that does not provide an airtight seal, but an airtight sealing member may be provided about the gas flow interfaces of the base, such as about one or more of thebase conduit inlet 201 a andconduit outlet 201 b, to provide an airtight connection for gas flowing from the atomizer through the base conduit and into themouthpiece 4.

For example, the at least oneheating element 8 may be disposed below abottom surface 310 of thecontainer 7 that is adapted to receive the vaporizable product therein. In one embodiment, the heating element comprises a ceramic heating plate, such as an alumina plate. Theheating element 8 may be capable of resistively heating thecontainer 7 via thermal contact therewith, as in direct contact with thebottom surface 310. In one embodiment, theheating element 8 is attached to conductive elements such as wires leading to the power source (e.g. battery) to provide an applied voltage for the resistive heating. In one embodiment, thecontainer 7 adapted to receive and hold the vaporizable product comprises a thermally conductive ceramic material, such as alumina, such that placing the container is in thermal contact with the heating element causes heating of the container. - According to yet another embodiment, the
atomizer 3 comprises a bottom insulatingelement 9 comprising a spacer disposed between theheating element 8 andatomizer housing 10 that thermally insulates theheating element 8 from theatomizer housing 8. The bottominsulating element 9 may also act to secure the heating element in position at abottom end 312 of the container, such as in contact with the bottom surface of thecontainer 7. In one embodiment, the bottom insulating element comprises a ceramic having a lower thermal conductivity than the container and/or heating element, so as to thermally isolate the container and/or heating element from the atomizer housing. For example, in one embodiment the bottom insulating element can comprise a thermal conductivity of less than 4 W/mk, less than 3.5 W/mk and/or less than 3 W/mk, whereas the container and/or heating element may comprise a thermal conductivity of at least 10 W/mk, at least 15 w/mk and/or at least 20 W/mk. - According to another embodiment, the
atomizer 3 comprise a topinsulating element 311 that thermally insulates atop end 313 of thecontainer 7 from theatomizer housing 10. In one embodiment, the top insulatingelement 311 is configured to receive acarb cap 17 thereon. For example in one embodiment, the device 1 is configured to operate with acarb cap 17 positioned upstream of theatomizer 3, the carb cap comprising a stopper having aconduit 314 formed therein to provide a flow of ambient air into theatomizer 3. In one embodiment, thecontainer 7 is thermally insulated from theatomizer housing 10 by both the bottom insulatingelement 9 that positions the container within the housing at a bottom end of the container, and the top insulatingelement 311 that positions a top end of the container in the housing. In one embodiment, referring toFIG. 6C , the top insulatingelement 311 comprises inner and outer annularinsulating rings atomizer inlet 301, and is in communication with thefirst inlet 305 of thecontainer 7. In the embodiment as shown inFIG. 6A , theatomizer inlet 301 is directly above thefirst inlet 305, and/or theatomizer inlet 301 and first container inlet may comprise the same inlet. That is, in one embodiment, the atomizer inlet may be aligned with and lead to a container inlet positioned below the innerannular ring 5 of the top insulatingelement 311. - In one embodiment, the
atomizer 3 comprises an outerannular ring 6 that forms an annular jacket that is flush with the outer surface of the innerannular ring 5, and extends in an axial direction beyond the inner annular ring such that a portion of the interior surface of the outer annular ring is in contact with an outer surface of theatomizer housing 10. In one embodiment, the outerannular ring 6 may secure the innerannular ring 5 to theatomizer housing 10 via frictional forces and/or via a snap mechanism or other fastening mechanism between a portion of the interior surface of the outer annular ring and the outer surface of the atomizer housing. In one embodiment, the outer annular ring comprises an annular jacket that forms an airtight seal with the atomizer housing. - In one embodiment, one or more of the inner and outer
annular rings container 7 from theatomizer housing 10, by having a lower thermal conductivity. For example, one or more of the inner and outer annular insulating rings can comprise a thermal conductivity of less than 4 W/mk, less than 3.5 W/mk and/or less than 3 W/mk, whereas the container may comprise a thermal conductivity of at least 10 W/mk, at least 15 w/mk and/or at least 20 W/mk. IN one embodiment, abottom surface 315 of the inner annularinsulating ring 5 is in contact with anupper surface 316 of thecontainer 7. - In one embodiment, one or more of the
container 7 and/or thermally insulatingelement 311, such as the innerannular ring 5, comprise one ormore apertures 318 therein that correspond to the one or more containersecond outlets 306. For example, in one embodiment the innerannular ring 5 comprises one ormore indentations 320 formed in thebottom surface 315 thereof, such as about a circumference thereof, which form one ormore apertures 318 between thebottom surface 315 of the innerannular ring 5 and thetop surface 316 of thecontainer 7. In yet another embodiment, the innerannular ring 5 comprises one or more apertures formed in the body thereof, such as about a circumference thereof, to provide the one or more container outlets. In yet another embodiment, the container itself comprises one ormore apertures 318 formed in one or more walls thereof, wherein the one or more apertures comprise the one or moresecond container outlets 306. According to certain embodiments,first container inlet 305 introduces a gas flow received through the inner insulatingannular ring 5 into thecontainer 7, and the one or moresecond container outlets 306 flow gas out of the container through the one ormore apertures 318. Thesecond container outlets 306 may thus be a separate aperture and/or opening than thefirst container inlet 305, such that air comes through the inlet and passes through a separate outlet when exiting thecontainer 7. - Furthermore, in one embodiment, the top insulating
element 311 is removable from theatomizer housing 10 to allow access to thecontainer 7. For example, the insulatingelement 311 may be removable by simply lifting or twisting the top insulating element form theatomizer housing 10. According to yet another embodiment, theatomizer housing 10 comprises alower portion 322 that is threaded, and that may be complementary to a threaded socket in the first recessedregion 203 a of thebase 2, so the atomizer can be screwed into the threaded socket of the base. In yet another embodiment a lower portion of the atomizer housing may connects to the base via a magnet, span mechanism or other fastening feature. - According to one embodiment, atomizer housing at least partially directs gas from the one or more second
container gas outlets 306 along the internal atomizer gas flow path 308 (shown as a dashed line inFIG. 6B ), in a passage 324 formed between walls of thecontainer 7 and theatomizer housing 10. Theatomizer housing 10 can comprises one or more apertures/outlets 309 formed therein to flow gas from the internal atomizergas flow path 308 to theairtight passage 207 that is external to the atomizer housing in the first recessedregion 203 a of thebase 2. In one embodiment, the atomizer housing apertures/outlets 309 are located at a lower end of the atomizer housing, and theatomizer housing 10 redirects flow of the gas from the one or more secondcontainer gas outlets 306 in a downward direction along a passage 324 formed between the housing walls and container walls, to the atomizer housing apertures/outlets 309. As shown inFIG. 6B , in one embodiment a flow of gas through theatomizer 8 comprises a flow through the first container inlet into a top of the container, flow out of the container through second container outlets that are separate from the inlet, and that are towards a top 313 of the container, flow downward between the atomizer housing and container wall towards a bottom of the atomizer and through apertures of the atomizer towards the bottom of the atomizer housing. - In one embodiment, the one or more
second container outlets 306 are located radially externally to thefirst container inlet 305, and/or are positioned in an arrangement circumferentially surrounding thefirst container inlet 305. Thesecond container outlets 306 may also be located towards a top end of the atomizer and/or container. In a further embodiment, the apertures and/oroutlets 309 for exhausting gas from the atomizer are located below the first container inlet and/or second container outlet, towards a lower end of the atomizer. - Further embodiments of the atomizer are described herein. For example, in one embodiment, inside the
atomizer housing 10, a container comprising abowl 7 is positioned on top of theheating element 8, and may be made of a highly thermally conductive material, which can include ceramic, quartz, or metals, allowing efficient heat transfer. Theheating element 8 and thebowl 7 are secured and insulated by the bottom insulatingelement 9 and top insulatingelement 311 respectively, these two elements firmly locating theheating element 8 andbowl 7 within the atomizer. These two elements are made with low thermally conductive, yet high heat withstanding, material so that minimal heat is lost from the heating element and bowl. The top insulating element comprises an outer annularring comprising sleeve 6, made of an insulating material, like silicone or plastic. Thesleeve 6 fastens to thehousing 10 and makes an airtight seal while the innerannular ring 5 insulates and positions thebowl 7. Thesleeve 6 may also protect the user from heat and serves as a grip for screwing and unscrewing the atomizer. - After extended use the
bowl 7 may become dirty. Because the top insulating element comprising in innerannular ring 5 and sleeve (6) are removable, the bowl can be taken out and easily cleaned. When the sleeve and top insulating element are assembled on the atomizer housing the bowl is held in place and a sealed airpath is formed. Air may enter the top of the bowl through acarb cap 17. Thecarb cap 17 may be capable of directing high velocity air to the bottom of the bowl, where the material is vaporized. Air then exits the top of the bowl as vapor through the second outlets which are apertures in the inner annular ring (5) above the bowl. These slots/apertures could also be cut into the top of the bowl. The vapor travels through the slots in the inner annular ring and down a gap formed between the bowl and the atomizer housing. The vapor can leaves the bottom of the atomizer and travels through an airpath into the mouthpiece.FIG. 6B shows a cross sectional view of the assembled atomizer with the carb cap and illustrates the airflow through the atomizer, entering through the carb cap and exiting out of the bottom of the atomizer. - In certain embodiments, material that leaks out of the
bowl 7 can seep down into the bottom of the atomizer near the connection point. Accordingly, it may be important for this area to be sealed so that the leaking material does not inhibit the passing of the current from power source to heating element. This seal is provided by theelectrode insulator 11 which holds theelectrode 12. The electrode insulator secures and holds separately the electrode from the housing. One lead wire ofheating element 8 can be held between the insulator and thehousing 10, the other lead wire can be held between the insulator and the electrode, therefore a current path in and out of the heating element can be created. There can be also grooves cut into the atomizer housing to position these lead wires. The electrode insulator can press the wires into these grooves and make a water and airtight seal against the housing and electrode which may prevents leaking. In certain embodiments, material may also leak out of the bottom of the atomizer through the air cuts in thehousing 10. Accordingly, it may be important that this material does not reach the connection point on the atomizer or the power source. When the atomizer is connected to the base, arib 14 running around the bottom of theatomizer housing 10 can create a seal. This seal can create a separation between the air holes and connection point and may prevent any material from reaching the electrical connection points on the atomizer or base. - Furthermore, because the
bowl 7,heating element 8 and innerannular ring 5 may interact with sticky material during use, there is a chance for them to become stuck together. In certain embodiments, if the bowl is twisted during use, for example while the user is tightening or untightening the atomizer by gripping the sleeve, the heating element could be twisted and could lead to subsequent breaking of its lead wires. Accordingly, features may be included in theatomizer housing 10 and innerannular ring 5. For example, slots in theatomizer housing 10 may line up with embossedfeatures 16 in the innerannular ring 5, so that the two lock together and cannot be twisted independently. This protects the heating element from damage when tightening or loosening the atomizer from the base. - In one embodiment, the bowl itself can include a
rib 15 around its bottom face, which is the face that interacts with the heating element. This rib may have three functions, it can positions the bowl, cover the heating element, and/or minimize heat loss, and it can shroud the heating element from debris. The debris could be water or liquid material that leaks down into the heating elements environment. Since the heating element may operate at a high temperature, a substance of room temperature contacting the heating element can result in significant thermal shock which could damage or permanently break the heating element. The rib on the bottom of the bowl blocks debris by creating a protective wall around the heating element. - Referring to
