Description

According to the prior art, the heaters used in the current devices for heating aerosol-generating devices in a non-combustion manner mainly comprise two types of resistive heaters and inductive heaters.

A system comprising an aerosol-generating device with an internal heater sheet is disclosed in a resistive heater such as CN106455714B (reference 1), in which the heater sheet is cyclically heated for use, and some compounds are attached and deposited, which require periodic cleaning, which would not only cause unpleasant by-products, but also affect its normal operation, even cause it to be damaged or broken. Furthermore, improper and careless insertion of the aerosol-generating article in the aerosol-generating device may also damage or destroy the heater chip.

An inductive heater such as CN106255429a (reference 2) discloses an aerosol-generating article having an internal susceptor in which an elongate susceptor is disposed generally longitudinally inside the aerosol-generating article, the susceptor being disposable and disposed of as the aerosol-generating article is consumed. However, the aerosol-generating article is heated sufficiently to effect aerosol formation only in the portion of the substrate very close to the elongate susceptor, while the distal substrate is difficult to atomize and utilize, resulting in substantial wastage of the substrate. In order to heat the substrate in the distal region of the elongate susceptor, the substrate adjacent the susceptor has to be overheated, which can result in burning of the substrate or the production of substantial amounts of by-products. Furthermore, the pre-heating time of the aerosol-generating article may be long, for example up to 30 seconds.

Therefore, there is a need for an aerosol generator with high aerosol generation rate, high substrate utilization and less byproducts. In view of this, the present utility model proposes an aerosol generator and a system.
