Description

Technical Field

[0001] This invention belongs to the field of heating appliances, and specifically relates to an aerosol generating device and an aerosol generating system. Background Technology

[0002] Traditional cigarettes release nicotine and flavor components from tobacco through combustion to satisfy consumer demand. Heated cigarettes, on the other hand, heat tobacco to its atomization temperature using an external heat source, producing smoke at a lower temperature than the tobacco's combustion temperature. This significantly reduces the amount of harmful substances produced during cigarette combustion and minimizes the harm of secondhand smoke to non-smokers.

[0003] Because heated cigarettes are heated at a lower temperature than they burn, the aroma components of tobacco are difficult to fully release compared to traditional cigarettes, resulting in insufficient smoke. Therefore, these cigarettes are less likely to be accepted by traditional smokers.

[0004] Patent application CN202010464317.6 discloses a sealed heated tobacco device. After a cigarette is inserted into the device, the cigarette holder is sealed. The oxygen content in the tobacco section and the holder decreases during heating. Therefore, even if the heating temperature is increased, the cigarette will not burn, thus increasing the release of aroma components from the tobacco. International patent application PCT / CN2020 / 118760 discloses a sealed cigarette that, by sealing the tobacco section, isolates it from oxygen, similarly increasing the heating temperature and thus enhancing the release of aroma components.

[0005] However, if users want to change their smoking method, they can only carry both regular heated tobacco devices (with an unsealed cigarette holder) and sealed heated tobacco devices, as well as both regular heated cigarettes (with an open smoke-generating section) and sealed cigarettes. This causes extreme inconvenience for users and increases the cost of purchasing tobacco devices and cigarettes.

[0006] To address the above problems, this invention is proposed. Summary of the Invention

[0007] The first aspect of the present invention provides an aerosol generating device, the aerosol generating device comprising: an aerosol generating product receiving tube, a base, and a movable sealing component;

[0008] The interior of the aerosol-generating product receiving tube is an aerosol-generating product receiving cavity;

[0009] The base is disposed below the aerosol-generating product receiving tube and is used to accommodate the movable sealing component and allow the movable sealing component to be in a first position and a second position different from the first position;

[0010] The base sidewall is provided with a vent hole that communicates with the outside. When the movable sealing component is in the first position, the movable sealing component blocks the channel between the vent hole and the aerosol generating product receiving cavity. When the movable sealing component is in the second position, the movable sealing component does not block the channel between the vent hole and the aerosol generating product receiving cavity, and the vent hole and the aerosol generating product receiving cavity are in communication.

[0011] Preferably, a first airflow channel is provided inside the base, and a second airflow channel is provided inside the movable sealing assembly;

[0012] When the movable sealing component is in the second position, the movable sealing component does not block the channel between the first vent and the aerosol generating product receiving cavity, and the vent and the aerosol generating product receiving cavity are connected through the first airflow channel and / or the second airflow channel.

[0013] Preferably, the base is provided with an axial guide groove, and the movable sealing assembly can move axially between a first position and a second position along the axial guide groove.

[0014] Preferably, the first position is located above or below the second position in the axial direction.

[0015] Preferably, the aerosol generating product receiving tube is provided with a clamping seal for clamping the aerosol generating product and sealing the gap between the aerosol generating product and the side wall of the cigarette receiving cavity, so that outside air cannot enter the distal lip of the aerosol generating product from the gap between the aerosol generating product and the side wall of the cigarette receiving cavity, but can only enter the distal lip of the aerosol generating product from the vent hole on the side wall of the base.

[0016] When the aerosol-generating product has vent holes on its sidewall, the clamping seal is used to selectively seal the vent holes on the sidewall of the aerosol-generating product.

[0017] Of course, if the clamping seal on the aerosol generating product receiving tube does not seal the vent hole on the side wall of the aerosol generating product, outside air can enter the perforated section of the aerosol generating product through the vent hole on the side wall of the aerosol generating product.

[0018] "Optional sealing" means that the clamping seal can seal or not seal the vent holes on the side wall of the aerosol generating article by adjusting the insertion depth of the aerosol generating article within the aerosol generating article receiving tube.

[0019] In a first embodiment, the movable sealing component includes: a puncturing element extending axially toward the aerosol generating article receiving cavity;

[0020] When the movable sealing assembly is in the first position, the tip of the puncture member extends into the aerosol-generating article receiving cavity; when the movable sealing assembly is in the second position, the tip of the puncture member does not extend into the aerosol-generating article receiving cavity.

[0021] In the second embodiment, the movable sealing component includes: a puncturing element extending axially toward the aerosol generating product receiving cavity;

[0022] When the movable sealing assembly is in the first position, the tip of the puncture member does not extend into the aerosol-generating product receiving cavity; when the movable sealing assembly is in the second position, the tip of the puncture member extends into the aerosol-generating product receiving cavity.

[0023] Of course, the length of the puncture component can also be adjusted as needed.

[0024] A second aspect of the present invention provides an aerosol generation system, comprising the aerosol generation device described in the first aspect and an aerosol generation article inserted into the aerosol generation article receiving cavity, wherein the aerosol generation article has a through hole or no through hole on its side wall, and the distal lip of the aerosol generation article is sealed by a puncturable membrane or not sealed by a puncturable membrane.

[0025] The movable blocking component is as described in the first embodiment;

[0026] The aerosol generation system operates in the following modes:

[0027] Operating mode 1: When the movable sealing component is in the first position, the tip of the piercing element pierces the distal lip of the aerosol generating product and directly performs suction.

[0028] Operating mode 2: When the movable sealing component is in the first position, the tip of the puncturing element pierces the distal lip of the aerosol generating product. Then, when the movable sealing component is in the second position, the tip of the puncturing element withdraws from the aerosol generating product cavity and suction is performed.

[0029] The two working methods described above, when adapted to different aerosol-generating products and aerosol-generating product insertion depths, have different suction methods, as detailed below:

[0030] Suction Method 1: When operating in mode 1, the aerosol generating product has a through hole on its side wall, and the distal lip of the aerosol generating product is sealed by a puncturable membrane. The puncturable membrane at the distal lip of the aerosol generating product is punctured by the tip of the puncturing member. However, the movable sealing component, even in the first position, can still block the channel between the cigarette receiving cavity and the ventilation hole. Therefore, the distal lip of the aerosol generating product is still sealed. At this time, by controlling the insertion depth of the aerosol generating product, the through hole may or may not be blocked by the clamping sealing member to perform the oxygen-deficient suction process.

[0031] When the through hole is blocked by the clamping seal, it cannot extract the flue gas, so the flue gas does not flow out easily; when the through hole is not blocked by the clamping seal, it can extract the flue gas, so the flue gas flows out more easily from the smoke-generating section.

[0032] Method 2: When operating in mode 1, the aerosol generating product has a through hole on its side wall, and the distal lip of the aerosol generating product is not sealed by the puncturable membrane. The movable sealing component, even in the first position, can still block the channel between the cigarette receiving cavity and the ventilation hole. Therefore, the distal lip of the aerosol generating product is still sealed. At this time, by controlling the insertion depth of the aerosol generating product, the through hole may or may not be sealed by the clamping seal to perform the oxygen-deficient suction process.

[0033] When the through hole is blocked by the clamping seal, it cannot extract the flue gas, so the flue gas does not flow out easily; when the through hole is not blocked by the clamping seal, it can extract the flue gas, so the flue gas flows out more easily from the smoke-generating section.

[0034] Method 3: When operating in mode 1, the aerosol generating product has no through holes on its side wall, and the distal lip of the aerosol generating product is sealed by a puncturable membrane. In this case, the puncturable membrane at the distal lip of the aerosol generating product is punctured by the tip of the puncturing member. However, the movable sealing component, even in the first position, can still block the channel between the cigarette receiving cavity and the ventilation hole. Therefore, the distal lip of the aerosol generating product remains sealed. At this time, an oxygen-deficient suction process is performed (because there are no ventilation holes on the aerosol generating product, it cannot extract smoke, so the smoke does not easily flow out).

[0035] Method 4: When operating in mode 1, the aerosol generating product has no through holes on its side wall and the distal lip of the aerosol generating product cannot puncture the membrane seal. The movable sealing component is in the first position and can block the channel between the cigarette receiving cavity and the ventilation hole. Therefore, the distal lip of the aerosol generating product is sealed. At this time, the oxygen-deficient suction process is carried out (because there are no ventilation holes on the aerosol generating product, it cannot play the role of extracting smoke, so the smoke does not easily flow out).

[0036] Method 5: Operating in mode 2, the aerosol generating product has a through hole on its side wall, and the distal lip of the aerosol generating product is sealed by a puncturable membrane. Then, the puncturable membrane at the distal lip of the aerosol generating product is punctured by the tip of the puncturing element, and the movable sealing component continues to be in the second position. The tip of the puncturing element withdraws from the aerosol generating product's receiving cavity, and then suction is performed. At this time, by controlling the insertion depth of the aerosol generating product, the through hole is either not blocked by the clamping seal or blocked by the clamping seal, which is a normal aerobic suction process.

[0037] The amount of smoke is greater when the through hole is not blocked by the clamping seal;

[0038] Suction Method Six: Operating in Mode Two, the aerosol generating product has a through hole on its side wall, and the distal lip of the aerosol generating product is not sealed by the puncturable membrane, so that the movable sealing component is in the second position. The tip of the puncture member is withdrawn from the aerosol generating product's receiving cavity, and then suction is performed. At this time, by controlling the insertion depth of the aerosol generating product, the through hole is either not blocked by the clamping seal or blocked by the clamping seal, which is a normal aerobic suction process.

[0039] The amount of smoke is greater when the through hole is not blocked by the clamping seal;

[0040] Method 7: When operating in mode 2, the aerosol generating product has no through holes on its side wall and the distal lip of the aerosol generating product is sealed by a puncturable membrane. Then, the puncturable membrane at the distal lip of the aerosol generating product is punctured by the tip of the puncturing element to allow air to enter. Then, the movable sealing component is placed in the second position, and the tip of the puncturing element is withdrawn from the aerosol generating product cavity. Then, suction is performed to carry out the normal aerobic suction process.

[0041] Method 8: Working in mode 2, the aerosol generating product has no through holes on its side wall and the distal lip of the aerosol generating product cannot puncture the membrane seal. Then, the movable sealing component is placed in the second position, the tip of the puncturing element is withdrawn from the aerosol generating product cavity, and then suction is performed to carry out the normal aerobic suction process.

[0042] When the smoke-generating section of the aerosol-generating product is filled with particulate smoke-generating material, the distal lip needs to be sealed with a puncturable membrane to prevent the particulate smoke-generating material from falling out.

[0043] A third aspect of the present invention provides an aerosol generation system, comprising the aerosol generation device described in another embodiment of the first aspect and an aerosol generation article inserted into the aerosol generation article receiving cavity, wherein the aerosol generation article has a through hole or no through hole on its side wall, and the distal lip of the aerosol generation article is sealed by a puncturable membrane or not sealed by a puncturable membrane.

[0044] The movable blocking component is as described in the second embodiment;

[0045] The aerosol generation system operates in the following modes:

[0046] Operating mode 1: When the movable sealing component is in the first position, the tip of the puncturing element does not penetrate the distal lip of the aerosol generating product, and suction is performed directly;

[0047] Operating mode 2: The movable sealing component is moved from the first position to the second position, and the tip of the puncturing component is inserted into the aerosol generating product receiving cavity, and then suction is performed.

[0048] The two working methods described above, when adapted to different aerosol-generating products and aerosol-generating product insertion depths, have different suction methods, as detailed below:

[0049] Suction Method 1: When operating in mode 1, the aerosol generating product has a through hole on its side wall and the distal lip of the aerosol generating product is sealed by a puncturable membrane. Then the movable sealing component is in the first position. At this time, by controlling the insertion depth of the aerosol generating product, the through hole may or may not be sealed by the clamping seal to carry out the oxygen-deficient suction process.

[0050] When the through hole is blocked by the clamping seal, it cannot extract the flue gas, so the flue gas does not flow out easily; when the through hole is not blocked by the clamping seal, it can extract the flue gas, so the flue gas flows out more easily from the smoke-generating section.

[0051] Method 2: Working in mode 1, the aerosol generating product has a through hole on its side wall, and the distal lip of the aerosol generating product is not sealed by the puncturable membrane. The movable sealing component is in the first position and can block the channel between the cigarette receiving cavity and the ventilation hole. Therefore, the distal lip of the aerosol generating product is still sealed. At this time, by controlling the insertion depth of the aerosol generating product, the through hole is either blocked by the clamping seal or not, so as to carry out the oxygen-deficient suction process.

[0052] When the through hole is blocked by the clamping seal, it cannot extract the flue gas, so the flue gas does not flow out easily; when the through hole is not blocked by the clamping seal, it can extract the flue gas, so the flue gas flows out more easily from the smoke-generating section.

[0053] Method 3: When operating in mode 1, the aerosol generating product has no through holes on its side wall, and the distal lip of the aerosol generating product is sealed by a puncturable membrane. The movable sealing component is in the first position and can block the channel between the cigarette holder cavity and the ventilation hole. Therefore, the distal lip of the aerosol generating product is still sealed. At this time, the oxygen-deficient suction process is carried out (because there are no ventilation holes on the aerosol generating product, it cannot play the role of extracting smoke, so the smoke does not easily flow out).

[0054] Method 4: When operating in mode 1, the aerosol generating product has no through holes on its side wall and the distal lip of the aerosol generating product cannot puncture the membrane seal. The movable sealing component is in the first position and can block the channel between the cigarette receiving cavity and the ventilation hole. Therefore, the distal lip of the aerosol generating product is sealed. At this time, the oxygen-deficient suction process is carried out (because there are no ventilation holes on the aerosol generating product, it cannot play the role of extracting smoke, so the smoke does not easily flow out).

[0055] Method 5: Working in mode 2, the aerosol generating product has a through hole on its side wall and the distal lip of the aerosol generating product is sealed by a puncturable membrane. Then, the puncturable membrane at the distal lip of the aerosol generating product is punctured by the tip of the puncturing element. At this time, by controlling the insertion depth of the aerosol generating product, the through hole is either not blocked by the clamping seal or blocked by the clamping seal, which is a normal oxygen suction process.

[0056] The amount of smoke is greater when the through hole is not blocked by the clamping seal;

[0057] Suction Method Six: Working in Mode Two, the aerosol generating product has a through hole on its side wall, and the distal lip of the aerosol generating product is not sealed by a puncturable membrane. In this case, by controlling the insertion depth of the aerosol generating product, the through hole is either not blocked by the clamping seal or blocked by the clamping seal, which is a normal oxygen suction process.

[0058] The amount of smoke is greater when the through hole is not blocked by the clamping seal;

[0059] Suction Method 7: When operating in mode 2, the aerosol generating product has no through holes on its side wall and the distal lip of the aerosol generating product is sealed by a puncturable membrane. When the movable sealing component is in the second position, the puncturable membrane at the distal lip of the aerosol generating product is punctured by the tip of the puncturing component to allow air to pass through and suction is performed. This is a normal aerobic suction process.

[0060] Method 8: When operating in mode 2, there are no through holes on the side wall of the aerosol generating product, and the distal lip of the aerosol generating product cannot puncture the membrane seal. When the movable sealing component is in the second position, suction is performed, and the normal aerobic suction process is carried out.

[0061] The above technical solutions can be freely combined, provided they do not contradict each other.

[0062] Compared with the prior art, the present invention has the following beneficial effects:

[0063] 1. The aerosol device of the present invention includes a movable sealing component, which can be moved to seal or not seal the bottom of the aerosol generating product receiving cavity. When the movable sealing component seals the bottom of the aerosol generating product receiving cavity, the smoke-generating section of the aerosol generating product is sealed, allowing for oxygen-deficient heating of the smoke-generating section, thus increasing the heating temperature of the smoke-generating section without concern for combustion. The smoke-generating material in the smoke-generating section can be heated more fully to release aerosols. When the movable sealing component does not seal the bottom of the aerosol generating product receiving cavity, the smoke-generating section of the aerosol generating product is sealed. Airflow passes through the aerosol generating product for normal suction. Therefore, users can freely adjust the position of the movable sealing component according to the type of aerosol generating product to meet different suction needs.

[0064] 2. In a preferred embodiment, a puncture element may also be provided on the movable sealing assembly. When the distal lip of the aerosol generating article is sealed by the puncturable membrane, the puncture element can also be used to puncture the puncturable membrane to allow airflow to pass through the aerosol generating article for normal suction.

[0065] 3. This invention achieves airway conversion simply by setting up a socketed base and a movable sealing component. It is simple, easy to assemble, and practical.

[0066] 4. During the oxygen-deficient extraction process, if the perforated section of the aerosol generating product has ventilation holes, outside air can flow into the aerosol generating product through these holes. Compared to the smoke-generating section, the perforated section has a higher airflow velocity and lower pressure, which can accelerate the outward flow of flue gas from the smoke-generating section to some extent, thus playing a role in extracting flue gas. In addition, the inflow of outside air into the aerosol generating product through the ventilation holes can cool the flue gas and increase the amount of smoke. Attached Figure Description

[0081] like Figure 1-3 An aerosol generating device is disclosed, comprising: an aerosol product receiving tube 2, a base 7, and a movable sealing assembly. Other components of the aerosol generating device, such as a battery and a control system, are not shown. Figure 1-3 Only the upper part of the aerosol generating device and the aerosol generated product 5 are shown.

[0082] The aerosol-generating product receiving tube 2 is a hollow cylinder, and its interior is an aerosol-generating product receiving cavity.

[0083] A clamping seal 1 is provided on the inner wall of the aerosol-generating product receiving tube 2 to clamp and seal the aerosol-generating product. In this embodiment, the clamping seal 1 is a soft sealing and bonding component such as latex, and is annular in shape. The clamping seal 1 can be provided on the inner wall of the aerosol-generating product receiving tube 2 by means of adhesion or snap-fit. Of course, in alternative embodiments, it can also be a section with a reduced inner diameter or an inner flange provided on the inner wall of the aerosol-generating product receiving tube 2 to achieve clamping or sealing of a specified section of the aerosol-generating product 5. In particular, when a through hole 521 is provided on the side wall of the perforated section 52 of the aerosol-generating product 5, by adjusting the insertion depth of the aerosol-generating product 5 into the aerosol-generating product receiving tube 2, the clamping seal 1 can be controlled to clamp at the through hole 521 to seal the through hole 521; or the clamping seal 1 can be controlled not to clamp at the through hole 521, and the through hole 521 is not sealed. The inner wall of the aerosol generating product receiving tube 2 can be provided with protrusions to adjust the insertion depth of the aerosol generating product 5.

[0084] The base 7 is disposed below the aerosol-generating product receiving tube 2, and the two are integrally connected. The base 7 is basically a hollow cylinder with an outer diameter slightly larger than that of the aerosol-generating product receiving tube 2, used to accommodate the movable sealing component and allow the movable sealing component to move in a predetermined manner. The movable sealing component can be in a first position and a second position different from the first position. Two symmetrical vent holes 71 are opened on the side wall of the base 7 near the aerosol-generating product receiving tube 2 to communicate the cavity inside the base 7 with the outside air. At the same time, the cavity inside the base 7 is also directly connected to the aerosol-generating product receiving cavity when there is no movable sealing component to seal it.

[0085] The movable sealing assembly includes an active member 4 and a driven member 3 that are interlocked with each other. The active member 4 has an L-shaped pushing part 41, which is located on the outermost radial side and extends radially relative to the base 7 and extends downward against the outer wall of the base 7 to serve as a point of force to push the entire movable sealing assembly to move axially.

[0086] An axially extending axial guide groove 72 is formed on the side wall of the base 7. The portion of the active member 4 adjacent to the pushing part 41 is located within the axial guide groove 72, allowing the entire movable sealing assembly to move axially along the axial guide groove 72. The active member 4 and the driven member 3 are inserted into each other in a basically cylindrical shape. The axial length of the active member 4 is less than the axial length of the cavity within the base 7, and the radial length of the active member 4 is approximately equal to the radial length of the cavity within the base 7. Therefore, there is a portion of the cavity within the base 7 that is not filled with the active member 4, which serves as a first airflow channel. The active member 4 has a cavity for receiving the driven member 3, into which the driven member 3 is inserted. The driven member 3 has an axially upward extending piercing needle 31 that protrudes axially relative to the active member 4 by a certain length, and is used to pierce the aerosol generating product 5 within the cavity for receiving the aerosol generating product.

[0087] The piercing needle 31 is made of sharp materials such as metal, ceramic, and heat-resistant plastic. The shape of the tip of the piercing needle 31 can be selected from needle-type, blade-type, or oblique-stabbing type. The oblique-stabbing type has the effect of piercing and lateral compression, so that after piercing and compression, the formed channel is larger, which facilitates the passage of air.

[0088] The first position is located above the second position in the axial direction. When the movable sealing component is in the first position, the upper end face of the active member 4 is in close contact with the aerosol generating product receiving cavity, the side wall of the active member 4 blocks the vent hole 71, and the upper end face of the active member 4 blocks the channel between the vent hole 71 and the aerosol generating product receiving cavity; when the movable sealing component is in the second position, the lower end face of the active member 4 is in close contact with the lower end face of the cavity of the base 7, the side wall of the active member 4 does not block the vent hole 71, and the first airflow channel is formed between the upper end face of the active member 4 and the upper end face of the cavity of the base 7, and the vent hole 71 is connected to the aerosol generating product receiving cavity through the first airflow channel.

[0089] In alternative embodiments, such as Figures 4-6 In the aerosol generating device shown, the driven member 3 has a second airflow channel communicating with the cavity in the base 7. The puncture needle 31 may be hollow. The driving member 4 has a radially extending pushing part 41. The pushing part 41 passes through the axial guide groove 72 and extends radially relative to the base 7 by a certain distance to serve as a point of force, which can push the entire movable sealing assembly to move axially.

[0090] The first position is located axially below the second position. When the movable sealing assembly is in the first position, the lower end face of the active member 4 is in close contact with the lower end face of the cavity of the base 7. The active member 4 seals the axial guide groove 72 and communicates with the cavity inside the base 7. When the movable sealing assembly is in the second position, the upper end face of the active member 4 is in close contact with the upper end face of the cavity of the base 7, and a first airflow channel is formed between the lower end face of the active member 4 and the lower end face of the cavity of the base 7. The axial guide groove 72 serves as a vent. The axial guide groove 72 communicates with the aerosol generating product receiving cavity through the first airflow channel and the second airflow channel.

[0091] In alternative embodiments, such as Figures 4-6 In the aerosol generation system shown, the vent 71 can also be opened on the side wall of the base 7 away from the aerosol generation product receiving tube 2.

[0092] The aerosol generating article 5 comprises, from the distal lip end to the lip end only, a smoke-generating section 53, a perforated section 52, and a filter section 51, which are sequentially joined together. The perforated section 52 has a through hole 521 on its sidewall. The distal lip end of the aerosol generating article 5 is sealed with a puncturable membrane. Alternatively, in an alternative embodiment, the through hole 521 may not be provided on the sidewall of the perforated section 52. In another alternative embodiment, the distal lip end of the aerosol generating article 5 may not be sealed with a puncturable membrane.

[0093] like Figure 1-3 The aerosol generation system shown works as follows:

[0094] When the distal lip of the aerosol generating article 5 is sealed by a puncturable membrane, and a through hole 521 is provided on the side wall of the aerosol generating article 5, so that the movable sealing component is in the first position, the tip of the puncturing needle 31 punctures the puncturable membrane at the distal lip of the aerosol generating article 5. Then, when the movable sealing component is in the second position, the tip of the puncturing needle 31 retracts, and the first airflow channel communicates with the aerosol generating article's receiving cavity to introduce air into the aerosol generating article for an oxygen extraction process. Figure 2 The direction of the middle arrow indicates the airflow direction during suction; at this time, by controlling the insertion depth of the aerosol generating product 5, the through hole 521 is sealed by the clamping seal 1.

[0095] like Figures 4-5 The aerosol generation system shown works as follows:

[0096] When the distal lip of the aerosol generating article 5 is sealed by a puncturable membrane, and a through hole 521 is provided on the side wall of the aerosol generating article 5, so that the movable sealing component is in the second position, the tip of the puncturing needle 31 punctures the puncturable membrane at the distal lip of the aerosol generating article 5, and the first airflow channel communicates with the aerosol generating article's receiving cavity to introduce air into the aerosol generating article for an oxygen extraction process. Figure 5 The direction of the middle arrow indicates the airflow direction during suction; at this time, by controlling the insertion depth of the aerosol generating product 5, the through hole 521 is sealed by the clamping seal 1.

[0097] Of course, it can also be done in Figure 4 In the direct heating and suction state, the aerosol generating product 5 is generated. At this time, the movable sealing component is in the first position to prevent the tip of the piercing needle 31 from piercing the puncturable membrane at the distal lip of the aerosol generating product 5. At this time, no air is introduced into the aerosol generating product 5, and the oxygen-deficient suction process is carried out. At this time, by controlling the insertion depth of the aerosol generating product 5, the through hole 521 is not blocked by the clamping seal 1, and the outside air enters through the through hole 521.

[0098] Of course, when the distal lip of the aerosol generating product is sealed by a puncturable membrane and no through holes are provided on the side wall of the aerosol generating product, the working mode of the aerosol generating system can be as follows: when the movable sealing component is in the second position, the tip of the puncturing member punctures the puncturable membrane at the distal lip of the aerosol generating product, and the vent is connected to the cavity of the aerosol generating product to introduce air into the aerosol generating product for an oxygen suction process;

[0099] Of course, when the distal lip of the aerosol generating article is not sealed by a puncturable membrane and no through hole is provided on the side wall of the aerosol generating article, the aerosol generating system can operate as follows: the movable sealing component is in the second position, and the vent is connected to the cavity of the aerosol generating article to introduce air into the aerosol generating article for an oxygen suction process.

[0100] Of course, various aerosol generating products and the working methods of aerosol generating systems can be combined to form other suction methods, such as those described in the Summary of the Invention.

[0101] The aerosol generating apparatus of the present invention can employ heating methods such as resistance-type or electromagnetic induction-type center heating, or resistance-type or electromagnetic induction-type circumferential heating. Alternatively, an electromagnetic acceptor can be placed on the aerosol generating article for electromagnetic induction heating. Furthermore, any suitable existing method, such as infrared or microwave, can be used to heat the aerosol generating article.

[0102] The specific heating element can be set in a conventional design, such as being located at the center of the base or on the outer periphery of the aerosol generating product receiving cavity, as long as it does not affect the function of the aforementioned aerosol generating device.
