In some example embodiments, where the inlet 132 is directly open to the exterior of the steam generator assembly 110, the inlet 152 and passage 154 may not be included in the electronic vaping device 100. Accordingly, inlet 132 provides fluid communication directly or indirectly between at least a portion of the interior 135 of the evaporator assembly 130 and the exterior of the steam generator assembly 110.

Accordingly, outlet 142 provides fluid communication between at least a portion of the interior 135 of the vaporizer assembly 130 and the exterior of the steam generator assembled 110.

Referring again to the evaporator assembly 130, the passageway assembly 133 is a structure that extends between the inlet 132 and the outlet 142 of the evaporator assembly 130 in the internal space 135, which is at least partially defined by the outer housing 131 of the evaporator assembly 130. How As shown, one or more internal surfaces 133I of channel assembly 133 define a hollow space, referred to herein as channel 193, that extends continuously through channel assembly 133 between inlet 132 and outlet 142. Accordingly, channel assembly 133 establishes fluid communication environment through a channel 193 formed by one or more internal surfaces 133I, between the inlet 132 and the outlet 142 through the evaporator assembly 130.

When the electronic vaping device 100 operates according to some exemplary embodiments, air may be drawn into the vaporizer assembly 130 through at least the inlet port 132 and the air may be further drawn through the vaporizer assembly 130 through the passage assembly 133 and further drawn out of the vaporizer assembly 130 and from the vapor generator assembly 110, and hence from the electronic vaping device 100 via the outlet 142, the channel 140, and the outlet 144. In some example embodiments and as shown in at least FIGS. 1B, the passage assembly 133 may be a cylindrical structure with one or more internal surfaces 133I that define a passage 193 between the inlet 132 and the outlet 142 for establishing fluid communication between the inlet 132 and the outlet 142 through the evaporator assembly 130 .

Referring again to the evaporator assembly 130, the dispenser interface assembly 150 is at least partially open to the fluid opening 134 and is therefore configured to be in fluid communication with the reservoir 112 through the fluid opening 134. Distribution mating element assembly 150 further extends at least partially into channel assembly 133. Distributing mating element assembly 150 may be in fluid communication with channel 193 due to the fact that distributing mating element assembly 150 is coupled to heating element 136. Accordingly, the distributor interface assembly 150 may be in fluid communication with both the reservoir 112 and the channel 193, and therefore may be configured to draw the finished composition for evaporation from the reservoir 112 into the channel 193.

In some exemplary embodiments, the heating element 136 may be located at least partially within the passage 193. The heating element 136 may be in fluid communication with the passage 193, and the passage assembly 133 may be configured to direct air received by the inlet 132 to flow through passage 193 in fluid communication with heating element 136. As shown at least in FIG. 1B, the heating element 136 is in fluid communication with the distribution interface element assembly 150 such that the heating element 136 is configured to heat at least a portion of the finished vaporization composition drawn into the channel 193 by the distribution interface element assembly 150. generating generated vapor in channel 193 such that the generated vapor can be drawn from the vaporizer assembly 130 and from the vapor generator assembly 110 and hence from the vaping device 100 through the outlet 142, the channel 140 and the outlet 144. For example , the heating element 136 may be directly coupled to a portion of the distribution interface element assembly 150 that extends at least partially into the channel 193, or may be at a sufficiently close distance from such a portion of the distribution interface element assembly 150 to be configured to generate sufficient heat to heat the finished vaporizing composition drawn into the interface portion of the distribution element assembly 150 to generate generated vapor.

Referring again to the interface distribution element assembly 150, the interface interface element assembly 150 comprises a first interface element 150-1 and a second interface element 150-2 that are coupled together and therefore configured to allow the finished composition to be vaporized between them.

As shown in FIG. 1B, the first interface distribution element 150-1 may extend at least partially through the channel assembly 133 and may be coupled to a heating element 136 in the channel assembly 133 such that the first interface interface element 150-1 is in fluid communication with channel 193 and heating element 136. Additionally, as shown in FIG. 1B, the first distribution interface element 150-1 may extend at least partially from the channel assembly 133 while still being in the interior space 135 of the evaporator assembly 130 such that the first distribution interface element 150-1 is in direct communication by fluid with the outer part of the channel assembly 133 in the internal space 135 of the evaporator assembly 130.

As shown in FIG. 1B, a second distribution interface element 150-2 may be located outside the duct assembly 133 in an interior space 135 of the evaporator assembly 130. A second distribution interface element 150-2 may be located in an interior space 175 that is defined by at least the outer housing 131 and one or more outer surfaces 133U of the channel assembly 133. Accordingly, it will be understood that the interior space 175 may be a limited portion of the interior space 135 that does not include the portion of the interior space 135 occupied by the channel assembly 133 and the channel 193 thus formed. As shown, at least a portion of the second distribution interface member 150-2 is open to the exterior of the evaporator assembly 130, for example, by directly adjacent to and surrounding the end of the fluid opening 134, as shown in FIG. 1B. The second distribution interface 150-2 may be configured to be in direct fluid communication with the reservoir 112 via a fluid opening 134 into which the second distribution interface 150-2 is directly exposed.

As further shown in FIG. 1B, the second distribution interface element 150-2 may be coupled to the first distribution interface element 150-1 outside the duct assembly 133 in the interior space 175, while the first distribution interface element 150-1 may be coupled to the heating element 136 such that the second distribution interface element 150-2 may be isolated from direct fluid communication with the channel 193, the heating element 136, or a combination thereof with the first distribution interface element 150-1. The finished vaporization composition drawn into the second mate distribution element 150-2 from the reservoir 112 through the fluid opening 134 may be further drawn from the second mate distribution element 150-2 into the first mate distribution element 150-1 and may be further drawn into the channel 193 and in fluid communication with the heating element 136 by the first interface distribution element 150-1, while the second interface interface element 150-2 remains isolated from direct fluid transmission at a sufficiently close distance from the heating element 136 to allow the heating element 136 to heat the finished composition for evaporation, held in the second distribution element 150-2 interface, to generate the generated steam.

Additionally and as shown in FIG. 1B, the first interface distribution element 150-1 can be isolated from direct fluid communication with the reservoir 112 by the second interface distribution element 150-2 such that the first interface distribution element 150-1 can be isolated from directly drawing the finished composition to evaporate from reservoir 112 independently of the second distribution element 150-2 interface.

In some exemplary embodiments, the second interface distribution element 150-2 is configured to restrict the flow of the finished composition for evaporation from the reservoir 112 into the first interface interface element 150-1, compared to embodiments in which the first interface interface element 150-1 is directly open into both the channel and the reservoir 112, and therefore can draw the finished composition for evaporation directly from the reservoir 112 into fluid communication with the heating element 136. Accordingly, the second distribution element interface 150-2 can be configured to limit the amount of the ready composition for evaporation contained in the interface interface element assembly 150 so that it does not exceed a certain amount, or may limit the flow rate of the finished composition for evaporation from the reservoir 112 into the channel assembly 133, or may be both.

For example, the first interface interface element 150-1 may comprise capillary material that is configured to be exposed to heat generated by the heating element 136 and may be configured to maintain a relatively high flow rate of the finished composition for vaporization through the internal structure of the first interface element 150-1. 1 interface, while the second distribution element 150-2 interface can be configured to maintain a relatively low flow rate of the finished composition for evaporation through the internal structure of the second distribution element 150-2 interface. The first distribution interface element 150-1 may include capillary material that is configured to be in direct contact with the heating element 136. The second distribution interface element 150-2 may have reduced resistance to heat that would be generated by the heating element 136 compared to durability of the first distribution element 150-1 interface. In some exemplary embodiments, the second distribution interface element 150-2 may have equal or greater resistance to heat that would be generated by the heating element 136 than the resistance of the first distribution interface element 150-1.

In some exemplary embodiments, the first mate distribution element 150-1 may be configured to maintain a first maximum flow rate of the finished vaporization composition through the internal structure of the first mate distribution element 150-1, and the second mate distribution element 150-2 may be configured to maintaining a second maximum flow rate of the finished composition for evaporation through the internal structure of the second distribution element 150-2 interface, where the value of the second maximum flow rate is equal to or less than one-half (ie, 50 percent) of the first maximum flow rate. The second distribution interface element 150-2 may be configured to transfer the finished composition to evaporate over at least twice the time period over which the first distribution interface element 150-1 is configured to transfer the finished composition for evaporation. In other words, the second distribution interface element 150-2 may have a “transfer speed” equal to or less than half the transfer speed of the first distribution interface element 150-1.

In some exemplary embodiments, the second distribution mating element 150-2 is configured to hold in the internal structure of the second distributing mating element 150-2 an amount of the finished vaporizing composition sufficient to support at least one complete steam generation session when the amount of the finished vaporizing composition is held. evaporation is further drawn from the second interface distribution element 150-2 into the first interface distribution element 150-1 and is further heated by the heating element 136 to produce steam. In some exemplary embodiments, the second distribution mating element 150-2 is configured to hold in the internal structure of the second distributing mating element 150-2 an amount of ready-to-evaporate composition sufficient to support up to three complete steam generation sessions, when the amount of ready-to-vaporize composition to be held is additional is drawn from the second mate distribution element 150-2 into the first mate distribution element 150-1 and is further heated by the heating element 136 to produce steam.

In some exemplary embodiments, the steam generator assembly 110 may be configured to generate at least one additional dose of steam even after all of the vaporizing formulation in tank 112 has been completely consumed because the amount of vaporizing formulation is sufficient to maintaining the generation of at least one additional dose of steam is still retained in the second distribution element 150-2 interface once the finished composition has been completely consumed to evaporate from the reservoir 112. In some exemplary embodiments in which the outer housing 113 is sufficiently transparent to allow externally monitoring the amount of the ready-to-evaporate composition held in the tank 112, the configuration of the second distribution mating element 15-2 to hold the ready-to-evaporate composition even after the finished vaporizing composition held in the tank 112 is consumed may allow the second dispensing mating element 150-2 serve as a buffer against complete depletion of the finished vaporizing composition from the steam generator assembly 110 prior to the replenishment of the finished vaporizing composition in the tank 112, thereby allowing the consumption of the finished vaporizing composition from the reservoir 112 through the outer housing 113 and replenishing the reservoir 112 with additional ready composition for evaporation, wherein the distribution element 150-2 interface can support the generation of at least one additional dose of steam in the event that the reservoir 112 is not first completely emptied, and after the tank 112 is emptied, at least one dose of steam is generated. Therefore, it will be understood that the second mate distribution element 150-2 may serve as a buffer against complete depletion of the finished composition for evaporation in the first mate distribution element 150-1, thereby protecting against overheating of the mate distribution element assembly 150 due to heating of the emptied first distribution element 150-1 interface with the heating element 136 and, therefore, improving the performance of the electronic vaping device 100 that includes the interface interface element assembly 150.

Due to the fact that the second distribution element 150-2 interface restricts the flow of the finished composition for evaporation from the reservoir 112 into the channel 193, the distribution element assembly 150, which contains both the first and second distribution elements 150-1, 150-2 interface , may be configured to control the flow of the finished vaporization composition from the reservoir 112 into the passage 193 and, therefore, ensure that a certain amount of the prepared vaporization composition is heated by the heating element 136 in the channel 193 to generate the generated vapor, thereby improving the performance characteristics of the electronic vaping device 100 and improving the experience of the electronic vaping device 100 and the effectiveness of said electronic vaping device in terms of using the pre-formulated vaping composition to generate the generated vapor. Such distribution interface element assembly 150 may also inhibit or prevent leakage of unvaporized finished vaporization composition from the first interface distribution element 150-1 into the channel assembly 133 and, therefore, potentially into the exterior of the steam generator assembly 110 and the exterior vaping device 100 through inlet ports 132, 152, or outlet ports 142, 144, or inlet ports 132, 152 and outlet ports 142, 144, thereby improving the performance of the vaping device and the efficiency in terms of use of the finished vaping device evaporation to generate generated steam. Such dispensing interface element assembly 150 may also prevent or prevent the storage of an excessive amount of vaporizer formulation in the interior space 135 of vaporizer assembly 130, thereby preventing loss of vaporizer assembly 100 from the electronic vaping device 100 in exemplary embodiments in which the vaporizer assembly 130 may be releasably coupled to the vapor generator assembly 110 by connecting connector assemblies 138, 148 and, therefore, may be disconnected and replaced with a replacement vaporizer assembly 130. Accordingly, the loss of the finished vaporizing composition from the electronic vaping device 100 The result of such replacement of the evaporator assembly 130 may be prevented by a distribution interface element assembly 150 configured to limit the amount of the finished vaporization composition held in the evaporator assembly 130 so that it is less than a certain amount, thereby improving performance and efficiency. electronic device 100 for vaping. Accordingly, the interface interface element assembly 150 may be configured to supply a limited amount of the finished vaporization composition from the reservoir 112 to the heating element 136.
