[0002] When an aerosol generating device heats the aerosol product using air, the heating element heats the airflow passing through the airflow channel, and the hot airflow then heats the aerosol product to generate aerosol. However, during the suction process, the heated aerosol product produces residue, which accumulates in the residue receiving cavity below the heating element, thus blocking the airflow channel and increasing suction resistance, resulting in a poor suction experience. Summary of the Invention

[0003] The purpose of this invention is to provide an aerosol generating device and system to solve the problem of increased suction resistance and a worse suction experience during the user's inhalation process.

[0021] An aerosol generating device is provided, the aerosol generating device comprising a bracket, a support tube, and a heating element;

[0022] The aerosol-generated product is at least partially contained in the first receiving cavity of the support tube;

[0023] The airflow passes sequentially through the air inlet channel, the first channel, and the airflow channel of the heating element before entering the aerosol to generate the product;

[0024] When the airflow channel is blocked, the airflow passes through the air inlet channel, the first air inlet hole, and the second channel in sequence before entering the aerosol to generate the product;

[0041] One embodiment of this application provides an aerosol generating device 10, such as... Figure 1 As shown, it includes a bracket 1 and a support tube 2.

[0042] Among them, bracket 1 has an air intake channel 11.

[0043] The bracket 1 is sleeved on the support tube 2, and a first channel 21 is defined between the inner wall of the bracket 1 and the outer wall of the support tube 2. The first channel 21 is connected to the air inlet channel 11. A first air inlet hole 22 is provided between the bracket 1 and the support tube 2. A second channel 23 is defined between the inner wall of the support tube 2 and the outer peripheral wall of the aerosol generating product 20. The second channel 23 is connected to the air inlet channel 11 through the first air inlet hole 22.

[0044] The support tube 2 includes a spacer 24 protruding from the inner wall of the support tube 2 toward the interior of the support tube 2. The spacer 24 divides the support tube into a first receiving cavity 241 and a second receiving cavity 242. The first receiving cavity 241 is used to receive at least a portion of the aerosol-generating article 20.

[0045] The heating element 3 is disposed in the second receiving cavity 242. The heating element 3 includes an airflow channel 31. The first channel 21 is connected to the airflow channel 31. When the airflow passes through the airflow channel 31, it can be heated by the heating element 3. The heated airflow will heat the aerosol generating product 20 to generate aerosol.

[0046] The aerosol generating device 10 of this application has a first air inlet 22 between the bracket 1 and the support tube 2, which defines a first channel 21 between the inner wall of the bracket 1 and the outer wall of the support tube 2, and defines a second channel 23 between the inner wall of the support tube 2 and the outer peripheral wall of the aerosol generating product 20. When the residue generated by the aerosol generating product 20 blocks the airflow channel 31 of the heating element 3, that is, when the first channel 21 is blocked, the airflow can flow through the second channel 23 through the aerosol generating product 20 to reach the user. The aerosol generating device 10 can still maintain a suitable suction resistance, thereby extending the service life of the aerosol generating device 10.

[0047] In one embodiment of this application, the aerosol generating article 20 has an aerosol forming matrix. The aerosol forming matrix may include nicotine. A nicotine-containing aerosol forming matrix may include a nicotine salt matrix. The aerosol forming matrix may include plant-based materials. Preferably, the aerosol forming matrix includes tobacco-containing materials. The aerosol forming matrix may include homogenized tobacco material, which can be formed by agglomerating particulate tobacco. Alternatively or additionally, the aerosol forming matrix may include tobacco-free materials. The aerosol forming matrix may include homogenized plant-based materials.

[0048] Aerosol forming matrices can include one or more of the following forms: powder, granules, pellets, fragments, filaments, strips, or sheets. Aerosol forming matrices can also contain one or more of the following materials: tobacco leaves, tobacco vein fragments, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco pulp, cast tobacco, and expanded tobacco.

[0049] The aerosol forming matrix may include tobacco extract. Tobacco extract can be obtained by extracting extracts from tobacco leaves and flowers using solvents, then extracting the extracts with ethanol, followed by drying, dehydration, desalting, and cooking of the raw materials, adding an extract with a special aroma, and performing ultrasonic-assisted extraction to finally obtain a tobacco extract with a specific flavor. In one embodiment of this application, tobacco extract is mainly used for tobacco flavoring, which can enhance the aroma, reduce off-flavors, and improve cigarette quality. Its aroma is realistic and natural, making it an excellent raw material for cigarette flavoring. In addition, tobacco extract can also be used in daily-use fragrances to provide unique aromas and flavors. In one embodiment of this application, the main components of the tobacco extract include furfuryl alcohol, benzyl alcohol, phytol, solanone, β-turfascin, β-ionone, hexahydrofarnesone, diene, megastigmatrienone, dihydroactinolone, isopentenyl solanone, indole, etc.

[0050] The aerosol forming matrix may contain at least one aerosol forming agent. An aerosol forming agent is used to describe any suitable known compound or mixture of compounds that promotes aerosol formation in use and is substantially resistant to thermal degradation at the operating temperature of the aerosol-generating article. Suitable aerosol forming agents are known in the art and include, but are not limited to: polyols such as propylene glycol, triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecenoate.

[0051] The aerosol forming matrix may include any suitable amount of aerosol forming agent. For example, the content of the aerosol forming agent, on a dry weight basis, may be equal to or greater than 5% of the aerosol forming matrix, and preferably greater than 30% by weight on a dry weight basis. On a dry weight basis, the aerosol forming agent content may be less than about 95%. Preferably, the content of the aerosol forming agent is as high as about 55%.

[0052] The aerosol forming matrix may also contain tobacco or non-tobacco volatile flavoring compounds that are released upon heating of the aerosol forming matrix. The aerosol forming matrix may also contain one or more encapsulations, which may include, for example, additional tobacco or non-tobacco volatile flavoring compounds, and such encapsulations may melt during heating of the aerosol forming matrix.

[0053] Aerosol-forming matrices can be provided on or embedded in a thermally stable carrier. The term "thermally stable" as used herein refers to a material that is substantially non-degradable at temperatures typically heated to which the aerosol-forming matrix is ​​located (e.g., from about 150°C to about 300°C). The carrier can take the form of powder, granules, pellets, fragments, filaments, strips, or sheets. The aerosol-forming matrix can be deposited on the surface of the carrier in the form of, for example, flakes, foams, glues, or pastes. The aerosol-forming matrix can be deposited on the entire surface of the carrier, or alternatively, it can be patterned to provide non-uniform flavor delivery during use.
