Description

Technical Field

[0001] This application relates to the field of heated non-combustible aerosol generation technology, and in particular to an aerosol generation product and an aerosol generation system. Background Technology

[0002] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0003] Examples of such products include heating devices that release compounds by heating rather than burning materials. For example, the material may be tobacco or other non-tobacco products, which may or may not contain nicotine. Known tobacco or other non-tobacco products are produced by doping or mixing aerosol-forming agents such as glycerin, flavorings, and binders into tobacco or non-tobacco materials, which generate an aerosol for the user to inhale when heated. Known tobacco or other non-tobacco products are made by preparing tobacco materials or other non-tobacco plant tissues into filaments or sheets, loading aerosol-forming agents, flavorings, and binders onto particles or sheets of tobacco materials or other non-tobacco plant tissues, and then pressing and winding them into a cylindrical shape using a cigarette-making machine. The materials within these prepared tobacco or other non-tobacco products are consumed by the heating device and then discarded or replaced entirely. Utility Model Content

[0064] The cover element 210 is connected to the main body portion 220 via a pin 230; and the cover element 210 is movable relative to the main body portion 220, specifically as follows: Figure 1 The cover element 210, indicated by the middle arrow P1, can rotate about the pin 230 relative to the main body 220, thereby selectively opening or closing the receiving cavity 240.

[0065] exist Figure 1 and Figure 2 As shown, when the cover element 210 is in the open state, the opening of the receiving cavity 240 at the first end 221 is open or exposed, facilitating user operation to receive or remove the aerosol generating article 100 from the receiving cavity 240. When the aerosol generating article 100 is received in the receiving cavity 240, at least a portion of the aerosol generating article 100 is exposed outside the opening of the receiving cavity 240, allowing the user to remove the aerosol generating article 100 from the receiving cavity 240 by pinching or holding the exposed portion of the aerosol generating article 100 with their fingers. Figure 1 and Figure 2 As shown, a clearance groove 214 is defined inside the cover element 210; when the aerosol generating article 100 is received in the receiving cavity 240, the exposed part of the aerosol generating article 100 extends into the clearance groove 214 when the cover element 210 is in the closed state, and can cover the exposed part of the aerosol generating article 100 located outside the receiving cavity 240.

Specifically, when the cover element 210 is moved to the closed state, the receiving cavity 240 and the clearance groove 214 engage to jointly define the receiving cavity; and when the cover element 210 is moved to the closed state, the receiving cavity is closed. When the cover element 210 is moved to the open state, the receiving cavity 240 and the clearance groove 214 separate, thereby opening the receiving cavity.

[0067] In an embodiment, the receiving cavity 240 is arranged to extend longitudinally; when the cover element 210 opens the receiving cavity 240, the aerosol generating article 100 can be received from outside the main body portion 220 into the receiving cavity 240 or removed from the receiving cavity 240.

[0068] In an embodiment, when the aerosol generating article 100 is received in the receiving cavity 240, the cover element 210, in the closed state, abuts against the downstream end 120 of the aerosol generating article 100, thereby stably clamping or holding the aerosol generating article 100 within the main body portion 220 and / or the heating device 200. Specifically, according to Figure 1 and Figure 2 As shown, in one embodiment, the cover element 210 further includes an abutment protrusion 215, at least partially located within the clearance groove 214; the abutment protrusion 215 abuts against the downstream end 120 of the aerosol generating article 100 when the aerosol generating article 100 is received in the receiving cavity 240 and the cover element 210 is in the closed state. In one aspect, the abutment protrusion 215 provides longitudinal retention for the aerosol generating article 100; in another aspect, the abutment protrusion 215 forms or defines a second air gap between the downstream end 120 of the aerosol generating article 100 and the cover element 210; the second air gap is between the downstream end 120 of the aerosol generating article 100 and the inner surface of the cover element 210.

[0069] In this embodiment, the aerosol generating article 100 is designed to be assembled and prepared by the user; the aerosol generating article 100 is only used to generate aerosols and does not have a typical filter or the like for the user to inhale; and when the aerosol generating article 100 is received in the heating device 200, the aerosol generating article 100 is completely contained within the heating device 200; and the aerosol generating article 100 has no exposed or protruding parts, such as a filter or the like, outside the heating device 200.

An outlet 216 is arranged or defined on the nozzle 211 for dispensing aerosol to the user. When the aerosol generating article 100 is received within the receiving cavity 240, and the cover element 210 is in the closed state, the outlet 216 is in airflow communication with the aerosol generating article 100 in the receiving cavity 240 for the user to inhale the aerosol.

[0071] exist Figure 1 and Figure 2 In the illustrated embodiment, the cover element 210 further defines:

[0072] A filter element holding chamber 213 is provided for receiving and holding the filter element 300. In an embodiment, the filter element 300, which is separate from or independent of the aerosol generating article 100, is received in the filter element holding chamber 213 by user operation for filtration before the aerosol is delivered to the outlet 216.

[0073] In some embodiments, the filter element holding cavity 213 is connected to the air outlet 216; or, the air outlet 216 is defined by the filter element holding cavity 213. In use, the user can receive the filter element 300 in the filter element holding cavity 213 and remove it from the filter element holding cavity 213 through the air outlet 216.

[0076] Cooling chamber 212 is located between clearance groove 214 and filter element holding chamber 213; and in use, cooling chamber 212 at least partially defines a portion of the airflow channel for aerosol output to outlet 216; during suction, aerosol from aerosol generation article 100 output from receiving chamber 240 passes through cooling chamber 212 and filter element 300 and is then suctioned by the user from outlet 216, such as... Figure 2 As indicated by arrow R3. In use, the cooling chamber 212 is used to cool the aerosol delivered to the opposing filter element 300. In embodiments, the volatile substances of the aerosol can be cooled within the cooling chamber 212 to create a temperature suitable for user inhalation.

For example, in Figure 1 and Figure 2 In the closed state, the cooling chamber 212 extends longitudinally along the heating device 200; the longitudinally extending cooling chamber 212 ensures that the airflow through the cover element 210 is longitudinally oriented without significant radial deviation. The cover element 210 can cool the temperature of the aerosol stream being drawn through by means of heat transfer. The components of the aerosol will interact with the space within the cooling chamber 212 and lose thermal energy. The cover element 210 may include ceramic, metal, or organic polymer plastic, etc. In some embodiments, the temperature of the aerosol stream may decrease by more than 10 degrees Celsius as it is drawn through the cooling chamber 212. In some embodiments, the temperature of the aerosol stream may decrease by more than 25 degrees Celsius or more than 30 degrees Celsius as it is drawn through the cooling chamber 212.
