Abstract: The present invention relates to a testing equipment and method for testing a susceptor arrangement in simulated heating conditions of a heated susceptor arrangement arranged in an aerosol-generating device during a user experience. The testing equipment comprises a holder module comprising a holder for receiving a susceptor arrangement to be tested, a control module comprising an inductive heating arrangement and a measurement device comprising a control circuit, wherein the inductive heating arrangement is configured to generate an alternating magnetic field for inductively heating a susceptor arrangement. The measurement device is configured to determine values associated to physical characteristics of the susceptor arrangement from measurements related to a load applied to the control circuit responsive to a susceptor arrangement in operational communication with the inductive heating arrangement, and the control circuit is configured to power the inductive heating arrangement for one test cycle or several subsequent test cycles of the susceptor arrangement and configured to determine if determined values associated to physical characteristics of the susceptor arrangement correspond to predetermined susceptor values.

Abstract: 本申请提供了一种气溶胶产生装置和气溶胶产生装置的控制方法，其中，气溶胶产生装置包括：壳体，壳体设有容纳腔，容纳腔能够被开启后关闭；微波发生装置，位于容纳腔内，微波发生装置设有微波控制电路；第一检测件，设于容纳腔，第一检测件与微波控制电路电连接，第一检测件检测到容纳腔被开启时，将微波控制电路断路。如果第一检测件检测到容纳腔被开启，第一检测件的检测信号发到控制器，控制器控制微波控制电路断路，即使此时检测到需要通过微波作用于气溶胶基质而产生气溶胶的信号，微波控制电路也无法控制执行电路通路，所以不会产生微波，避免微波发生泄漏对用户造成伤害。

Abstract: Many current aerosol-generating devices are complex, costly, bulky, and suffer from degraded airflow during use. To address at least some of these issues, there is provided an aerosol-generating device comprising a housing comprising a sidewall defining a through-hole which extends from a mouth end of the device to an opposite distal end of the device so as to form an airflow path through the device. The through-hole defines at the mouth end a receptacle for receiving an aerosol-generating article and at the distal end an air inlet for enabling ambient air to be drawn into the receptacle and thereby through the aerosol -generating article. The aerosol-generating device further comprises one or more electric or electronic components arranged laterally adjacent to the sidewall and at least partly surrounding the sidewall. In this way, a compact yet fully functional aerosol-generating device may be provided in which the control of airflow is greatly simplified.
