Abstract

dispositivo gerador de aerossol com detecção de tragada. a presente invenção refere-se a um dispositivo gerador de aerossol para gerar um aerossol a partir de um substrato formador de aerossol. o dispositivo gerador de aerossol pode compreender um compartimento de dispositivo que define uma câmara para receber o substrato formador de aerossol; um canal de fluxo de ar que se estende a partir de uma entrada de ar no compartimento de dispositivo e através ou em comunicação fluida com a câmara; e um conjunto de sensor de tragada que compreende um elemento de transferência de calor e um sensor de temperatura em contato com o elemento de transferência de calor. uma primeira porção do canal de fluxo de ar é pelo menos parcialmente definida por uma parede do canal de fluxo de ar e uma segunda porção do canal de fluxo de ar é pelo menos parcialmente definida pelo elemento de transferência de calor, a segunda porção do canal de fluxo de ar sendo adjacente à primeira porção e fora da câmara. pelo menos uma dentre a condutividade térmica ou difusividade térmica do elemento de transferência de calor é maior do que a respectiva condutividade térmica ou difusividade térmica da parede do canal de fluxo de ar.aerosol generating device with puff detection. The present invention relates to an aerosol generating device for generating an aerosol from an aerosol-forming substrate. the aerosol-generating device may comprise a device housing defining a chamber for receiving the aerosol-forming substrate; an airflow channel extending from an air inlet in the device housing and through or in fluid communication with the chamber; and a puff sensor assembly comprising a heat transfer element and a temperature sensor in contact with the heat transfer element. a first portion of the airflow channel is at least partially defined by a wall of the airflow channel and a second portion of the airflow channel is at least partially defined by the heat transfer element, the second portion of the airflow channel is of air flow being adjacent to the first portion and outside the chamber. at least one of the thermal conductivity or thermal diffusivity of the heat transfer element is greater than the respective thermal conductivity or thermal diffusivity of the air flow channel wall.
