The aerosol generating device 10 includes a generating assembly 100 and a host 700. The host 700 provides electrical power to the generating assembly 100 for the generating assembly 100 to generate a gaseous substrate for ingestion by a user. The generation assembly 100 includes an atomizer 200. The atomization core in the atomizer 200, by the power supplied by the host 700, causes the gaseous phase within the generation assembly 100 to vaporize to form a gaseous matrix.

In the prior art, as the population of users put different demands on the aerosol generating device and the technology of the aerosol generating device gradually develops and perfects, the aerosol generating device 10 can be further provided with a wind power component which is used for adjusting the temperature, the concentration and the flow resistance of the gaseous substrate so as to be used by different users. However, the wind assembly is typically located inside the aerosol generating device 10, typically in the cartridge between the battery and the atomizer 200, and replacement and maintenance of the wind assembly is inconvenient.

Therefore, the invention provides the aerosol generating device, the wind power assembly is externally arranged on the cylinder body of the aerosol generating device, and the maintenance and the replacement of the aerosol generating device are convenient. Specifically, the method comprises the following steps:

the invention provides an aerosol generating device, which comprises a generating assembly 100 and a host 700. As shown in fig. 1, the aerosol generating device further comprises:

a first housing 300 having a first cavity 300a for housing the generating assembly 100 and the atomizer 200;

a second case 400, the second case 400 being connected to a sidewall of the first case 300; and is configured with a second cavity 400 a; the second cavity 400a is communicated with the first cavity 300 a;

a wind power assembly 500, said wind power assembly 500 being received in said second cavity 400 a. Wherein the output channel 100a of the generating assembly 100 is communicated with the first cavity 300 a; wind power assembly 500 is electrically connected to a main machine 700 and generator assembly 100 is electrically connected to main machine 700.

In the technical scheme of the invention, the host 700 provides electric energy to the wind power assembly 500 to drive the wind power assembly 500 to work, and gas flows are generated inside the first cavity and the second cavity; the host 700 provides electrical power to the generating assembly 100 to produce a gaseous substrate; the airflow generated by the wind power assembly 500 sequentially passes through the second cavity 400a and the first cavity 300a and enters the output channel 100a to adjust the concentration, concentration and flow resistance of the gaseous substrate for different users. The wind power assembly 500 is disposed in the second cavity 400a in the second housing 400, and the second housing 400 is coupled to the outer wall of the first housing 300 containing the generating assembly 100 and the atomizer 200, that is: the wind power assembly 500 is not in the same cavity as the generating assembly 100 and the atomizer 200, but is independently arranged in one cavity, so that the wind power assembly 500 can be a relatively independent structure of the aerosol generating device, and is convenient for repair, maintenance and replacement.

In addition, compared with the prior art, the aerosol generating device of the invention can at least have the following technical advantages: the wind module 500 does not accumulate aerosol matrix. In the prior art, residual gaseous substrates which are not sucked by a user can be solidified into aerosol substrates, and the aerosol substrates flow to the wind power assembly along a preset air channel under the action of the self gravity of the aerosol substrates, so that the aerosol substrates are accumulated at the wind power assembly, and the function of the wind power assembly is easy to gradually lose efficacy; in the present invention, after the user does not eat the gaseous substrate, the gaseous substrate is solidified into the aerosol substrate but is not in the same cavity as the generating assembly 100 because the wind power assembly 500 is externally disposed in the second cavity, the aerosol substrate does not flow and accumulate to the wind power assembly 500, and the function of the wind power assembly 500 is not affected by the accumulation of the aerosol substrate.

As a further solution to the above embodiment, the generating assembly 100 is provided with a first flow port (not shown in the sectional view, not labeled because the position of the first flow port is not on the same section as the second flow port 200b and the third flow port 300 b), and the output channel 100a is communicated with the first cavity 300a through the first flow port.

For example, the first flow-through opening may be a through-hole provided on a corresponding section of the electrode of the generating assembly 100, which is the location where the aerosol substrate is heated.

The output conduit of the generating assembly, the reservoir, etc. is housed within a third chamber, and the atomiser 200, when heated, changes the aerosol matrix in the reservoir to a gaseous matrix which is output through an output channel 100a in the output conduit to the mouth of the user for ingestion. When the output pipeline, the oil storage body and other structures of the generating assembly are accommodated in the third cavity, the outer wall of the output pipeline 100b and the atomizer 200 form a first annular passage 200a, and the first annular passage 200a is a part of the space of the third cavity.
