Description

Technical Field

[0001] The utility model belongs to the technical field of electronic cigarette double-chamber heating HNB devices, and particularly relates to an aerosol generating device. Background Art

[0002] At present, the HNB devices on the market are mainly divided into two types: central heating and circumferential heating. Each has its own matching cigarettes. Most cigarettes cannot match both central heating and circumferential heating devices at the same time. For example, the temperature resistance of some central heating cigarettes is poor. When heated by circumferential heating devices, the cigarette paper is prone to produce a burnt smell, affecting the customer's experience and health. There are also some circumferentially heated granular cigarettes with finer particles. When using central heating, the heating needle or heating sheet pierces the seal at the bottom of the cigarette, and the particles are easy to fall out. When users travel, it is inconvenient to carry two devices at the same time. If they only carry one of them, the form of smoking cigarettes will be limited, which brings inconvenience to users. Utility Model Content

Users can carry one device to meet the smoking requirements of these two types of HNB cigarettes. After atomization using the central heating component of the device, the circumferential heating component of the device can also be used for secondary atomization, thereby improving the utilization rate of cigarettes, saving users' usage costs and reducing the harm of discarded cigarettes to the environment.

[0023] ⑸ The cover of the aerosol generating device is designed with two stop surfaces on the left and right to prevent the user from mistakenly operating the cigarette bin cover to slide beyond the left and right limit positions, causing the bottom slide rail of the cigarette bin cover to disengage from the upper cover slide groove, and the sliding element to fall out of the upper cover assembly.

[0024] (6) The aerosol generating device has a compact structure and is easy to use. It enhances the social attributes of HNB devices, accelerates the process of replacing traditional cigarettes with harm-reducing HNB cigarettes, and improves the utilization rate of some cigarettes.
