END DEVICE FOR ELECTRONIC VAPING DEVICE, AND ELECTRONIC VAPING DEVICE CONTAINING SPECIFIED END DEVICE Russian patent published in 2022 - IPC A24F7/00 A24F47/00 

FIELD: tobacco industry.

SUBSTANCE: invention relates to electronic vaping or e-vaping devices. An end device for an electronic vaping device (EVD) contains the first channel structure having a surface at least partially forming the first channel having an inlet end and an opposite outlet end, wherein the first channel structure is made with the possibility of receiving source vapor from an external source through the inlet end of the first channel and directing received source vapor through the first channel to the outlet end of the first channel, and the second channel structure having a surface at least partially forming the second channel having an inlet end and an opposite outlet end, wherein the second channel structure is made with the possibility of receiving an air flow from the environment through the inlet end of the second channel and directing the air flow through the second channel to the outlet end of the second channel. At the same time, the second channel structure contains additive material located on the surface of the second channel structure, containing an additive and made with the possibility of releasing the specified additive into the air flow directed through the second channel. In this case, at least an intermediate structure of the first channel structure and the second channel structure physically isolates additive material from the first channel, so that additive material is made with the possibility of releasing the additive into the air flow directed through the second channel, regardless of source vapor directed through the first channel. The end device also contains: a node for introducing an additional additive, communicating via fluid with the first channel and made with the possibility of releasing the additional additive to source vapor directed through the first channel, so that the air flow directed through the outlet end of the second channel contains the additive, and source vapor directed through the outlet end of the first channel contains the additional additive.

EFFECT: reduction or minimization of the probability of interactions or chemical reactions between an additive and source vapor and/or an additive and an additional additive, thereby improving at least one of the quality and stability of mixed vapor containing the additive, source vapor and the additional additive.
