Description

Aerosol generating device and system Technical Field The present application relates to the field of heating non-combustion technology, and more particularly to an aerosol-generating device and system. Background Aerosol-generating devices are a type of appliance that utilize a heated non-combustion technique to heat an aerosol-generating substrate to generate an aerosol for inhalation by a user. The aerosol-generating device is typically formed with a receiving cavity for receiving an aerosol-generating substrate, and an airflow channel communicating the receiving cavity with the atmosphere. In the related art, an aerosol-generating substrate is heated in a receiving cavity to generate an aerosol, and air enters the receiving cavity along a first airflow path and mixes with the aerosol, and then flows out of the receiving cavity along a second airflow path into the respiratory system of a user. However, the ambient temperature is much lower than the temperature in the receiving chamber during heating, and cold air is very likely to cause condensate accumulation when entering the second air flow passage. Disclosure of utility model Embodiments of the present application provide an aerosol-generating device and system and at least for addressing the problem of condensate build-up at the intersection of air flows.
