Atomization module and aerosol generating device

Abstract

The present application provides an atomization module and an aerosol generation device. The atomization module includes a first housing having a first gas passage extending therethrough; a second housing having a cavity structure with an open end, the second housing covering at least a portion of the exterior of the first housing through the opening and connected to the first housing, forming a second gas passage between the first housing and the second housing, the second gas passage communicating with the first gas passage; and an aerosol generation module installed within the second housing and capable of generating aerosol. Because the first gas passage and the second gas passage communicate with each other, air flow within the atomization module during inhalation is ensured. Furthermore, because the second housing has an open end and the aerosol generation module is installed within the second housing, uniform heat exposure to the aerosol generation module is ensured. Furthermore, this prevents dirt from adhering to components within the aerosol generation device in which the atomization module is installed after inhalation, making cleaning the aerosol generation device easier.

Description

[Technical field]

[0001] The present application relates to the technical field of electronic atomization, and in particular to an atomization module and an aerosol generating device. [Background technology]

[0002] The Heat Not Burning (HNB) device is an electronic device that heats an aerosol-generating substrate (treated plant leaf products) without burning it. The heating device heats the aerosol-generating substrate to a high temperature that can generate aerosols but does not reach a point of combustion, allowing the aerosol-generating substrate to generate the aerosol desired by the user, on the premise of non-combustion.

[0003] Currently, non-combustion and heating devices on the market mainly adopt the resistance heating method. That is, the aerosol generating substrate is heated by inserting a central heating tip or a heating needle into the substrate from the center. Such devices require preheating before use, so the waiting time is long and inhalation and stopping cannot be performed freely. In addition, the aerosol generating substrate is unevenly carbonized and the baking of the aerosol generating substrate is insufficient, so the utilization rate is low. In addition, the heating tip of the HNB device is prone to causing dirt on the aerosol generating substrate removal device and the heating tip base, making cleaning difficult. In addition, the temperature of the aerosol generating substrate in the part in contact with the heating element rises too much, causing partial decomposition, which releases substances harmful to the human body. Therefore, instead of the resistance heating method, microwave heating technology is gradually becoming a new heating method. Microwave heating technology has the characteristics of being efficient, rapid, selective and without delay in heating, and has a heating effect only on materials with specific dielectric properties. The application advantages of adopting atomization by microwave heating include the following:

[0004] a. Microwave heating is radiation heating, not thermal conduction, so it is possible to achieve immediate inhalation and immediate stopping.

[0005] b. Since it does not have a heat generating tip, there is no problem with chip breakage or cleaning of the heat generating tip.

[0006] c. The utilization rate of the aerosol-generating substrate is high, and the consistency of the draw is high, resulting in a draw that is more similar to that of a cigarette.

[0007] However, in general, in the case of atomization by microwave heating, a conductor column through which microwaves are introduced is inserted into the aerosol-generating substrate, so that after inhalation, the aerosol-generating substrate is prone to have soot generated by combustion due to high-temperature heating that adheres to the conductor rod installed in the aerosol generating device, and cleaning is difficult. Summary of the Invention [Problem to be solved by the invention]

[0008] The present application aims to solve at least one of the technical problems existing in the prior art. [Means for solving the problem]

[0009] Thus, in a first aspect, the present application provides an atomization module.

[0010] In a second aspect, the present application provides an aerosol generating device.

[0011] In a first aspect, the present application provides an atomization module, the atomization module including: a first housing having a first gas path extending therethrough; a second housing configured to form a cavity structure with one open end, covered by at least a part of the outside of the first housing through the opening and connected to the first housing, forming a second gas path between the first housing and the second gas path, the second gas path communicating with the first gas path; and an aerosol generating module installed in the second housing and capable of generating an aerosol.

[0012] Therefore, the present application provides an atomization module including a first housing, a second housing, and an aerosol generating module. A first gas path is provided through the inside of the first housing. The second housing has a cavity structure with one end open. The second housing is provided to cover at least a part of the outside of the first housing through the opening and is connected to the first housing. A second gas path is formed between the first housing and the second housing. The second gas path is also connected to the first gas path. In this way, an intake gas path is formed that is connected to the inside of the atomization module, ensuring the flow of air inside the atomization module during inhalation.

[0013] Furthermore, the second housing has a cavity structure with one end open, and the aerosol generating module is installed in the second housing. By covering the first housing with the second housing, the aerosol generating module is placed in a tightly sealed environment. This further ensures that the aerosol generating module receives heat uniformly, improving the utilization rate of the aerosol generating module. In addition, the atomizing module provided in the present application does not need to be equipped with components such as a conductor rod, a heating tip, or a heating needle. This avoids the problem that these components are inserted into the atomizing module, causing soot adhesion between the aerosol generating module and the atomizing module, making cleaning difficult. Furthermore, since the bottom of the atomizing module is installed in a sealed state, the aerosol generating device in which the atomizing module is installed will not be contaminated after the atomizing module is installed in the aerosol generating device.

[0014] Specifically, the first housing and the aerosol generation module are in close contact with each other, which ensures the stability of the internal structure of the atomization module and ensures that air flows through the first gas path during inhalation, preventing air from escaping from the inside of the atomization module.

[0015] Specifically, the first and second housings are connected by an engagement groove to prevent the second housing from falling off.

[0016] Specifically, the first housing is one of a paperboard tube having a supporting function, a polylactic acid material tube, a polytetrafluoroethylene tube, a synthetic resin tube, a protein material tube, a vegetable rubber-based material tube, and a cellulose derivative material tube.

[0017] Specifically, the first and second housings are made of a low dielectric loss material that has a certain strength and can fix the shape, and can be made of one of a paperboard tube, a polylactic acid material, a polytetrafluoroethylene, a synthetic resin, a chemical fiber product, a nonwoven fabric, a ceramic plate, a PEEK material, and glass.

[0018] Specifically, the length of the atomization module is 30 to 70 mm, and preferably 40 to 50 mm.

[0019] In this way, the atomization module provided in the present application has a connected inhalation gas path formed therein, so that the flow of air inside the atomization module during inhalation is guaranteed. In addition, the second housing has a cavity structure with one end open so that the inside of the atomization module is a tightly sealed environment. This ensures that the aerosol generating module receives heat uniformly, so that the utilization rate of the aerosol generating module is improved. In addition, the atomization module provided in the present application does not need to be equipped with components such as a conductive rod, a heating tip, or a heating needle. This avoids the problem that these components are inserted into the atomization module and stick to the aerosol generating module, making cleaning difficult. In addition, the bottom of the atomization module is installed in a sealed state, so that the aerosol generating device in which the atomization module is installed will not be contaminated after the atomization module is installed in the aerosol generating device.

[0020] The atomization module based on the above technical solution in this application may further have the following additional technical features:

[0021] In the above technical solution, the first housing includes a first body section and a second body section connected to an end of the first body section. The second housing is covered on the outside of the second body section. A first pitch is provided between the second housing and the second body section, and a second pitch is provided between the second housing and the end of the second body section. The first pitch is used to form a second gas path, and the second pitch is used to form an air inlet of the second gas path.

[0022] In this technical solution, the first housing includes a first body section and a second body section. The second body section is connected to an end of the first body section, and the second housing is disposed outside the second body section. A first pitch is provided between the second housing and the second body section. A second pitch is provided between the second housing and the end of the second body section. The height of the second housing is lower than the end of the second body section.

[0023] In addition, in this technical solution, the first pitch between the second housing and the second main body section is used to form a second gas path, and the second pitch between the second housing and the end of the second main body section is used to form an air inlet of the second gas path. During the suction process, air outside the nebulization module enters the second gas path through the air inlet and then enters the inside of the nebulization module, so that the air flow inside the nebulization module is ensured.

[0024] Specifically, the outer diameter of the first body section and the outer diameter of the second housing are equal or approximately equal. The outer diameter of the first body section is 6 to 20 mm, and preferably 8 to 10 mm.

[0025] Specifically, the outer diameter of the second main body section is slightly smaller than the inner diameter of the second housing. The outer diameter of the second main body section is 4 to 18 mm, preferably 7 to 8.5 mm. The inner diameter of the second housing is 7.5 to 19 mm, preferably 7.5 to 9 mm.

[0026] In any of the above technical solutions, a storage space is formed between the second body section and the second housing, and the aerosol-generating module is located in the storage space. The atomization module further includes a plurality of protrusions that are spaced apart from each other on the bottom wall of the second housing and located in the storage space. The protrusions support the aerosol-generating module so as to communicate the second gas path with the first gas path.

[0027] In this technical solution, an accommodation space is formed between the second body section and the second housing. The atomization module further includes a plurality of protrusions. The aerosol generating module and the plurality of protrusions are both installed in the accommodation space. The plurality of protrusions are installed at intervals on the bottom wall of the second housing. In this way, the plurality of protrusions can provide support for the aerosol generating module. Since the plurality of protrusions are installed at intervals on the bottom wall of the second housing, a path connecting the second gas path and the first gas path can be formed between the second housing and the aerosol generating module. As a result, a connected suction path is formed inside the atomization module, which ensures the flow of air inside the atomization module during inhalation and reduces resistance during inhalation.

[0028] In any of the above technical solutions, the aerosol-generating module includes an aerosol-generating substrate configured to have a structure having a first through hole, and a heating member installed in the first through hole, capable of absorbing microwaves and heating the aerosol-generating substrate.

[0029] In this technical solution, the aerosol-generating module includes an aerosol-generating substrate and a heating element. The aerosol-generating substrate has a structure with a first through-hole, and the heating element is disposed in the first through-hole. In use, the heating element absorbs microwaves and uses the microwaves to heat the aerosol-generating substrate, thereby causing the aerosol to be generated in the aerosol-generating substrate.

[0030] Furthermore, in this technical solution, the heating element is installed in the first through-hole of the aerosol-generating substrate, so that when the aerosol-generating substrate is heated by microwaves, even the aerosol-generating substrate located at the periphery can be located in a strong microwave field, so that the aerosol-generating substrate at the periphery can be sufficiently heated and the heat received by the entire aerosol-generating substrate can be ensured to be uniform, thereby enhancing the atomization effect of the aerosol in the aerosol-generating substrate and improving the utilization rate of the aerosol-generating substrate.

[0031] Specifically, the main raw material for preparing the aerosol-generating substrate is tobacco leaves or herbs, and the forms of the aerosol-generating substrate include granules, sheets, powdery pieces, threads, pastes, crepes, porous aerogels, and capsules.

[0032] Specifically, the diameter of the aerosol-generating substrate is 4 to 17 mm, preferably 5 to 8 mm, and the height of the aerosol-generating substrate is 6 to 25 mm, preferably 8 to 12 mm.

[0033] Specifically, the heating element is a microwave absorbing material with relatively excellent high temperature resistance, and has the characteristics of good impedance matching, wide bandwidth, thin matching thickness, light mass, and strong absorption capacity, thereby enhancing the aerosol atomization effect in the aerosol-generating substrate.

[0034] In particular, the manufacturing material of the heating element may be one of the following: ferrite, ceramic-based material, silicon carbide, barium titanate, magnetic metal powder.

[0035] In any of the above technical solutions, the aerosol-generating substrate One end closer to the opening and the open end of the second housing have a preset distance therebetween.

[0036] In this technical solution, there is a preset distance between the end of the aerosol-generating substrate and the open end of the second housing, so that the length of the second body section is guaranteed. During inhalation, air enters the second gas path from the air inlet at the open end of the second housing, travels a preset distance, passes through the aerosol-generating substrate, and flows into the first gas path together with the aerosol. Also, leakage of the aerosol from the air inlet can be prevented.

[0037] In any of the above technical solutions, the first housing further comprises a second body section One end away from the first body section a positioning member disposed on the second body section and having a cross-sectional area smaller than a cross-sectional area of ​​the second body section, the aerosol-generating substrate being disposed over the positioning member through the first through-hole, and a free end of the positioning member being in contact with the heating member.

[0038] In this technical solution, the first housing further includes a positioning member. The positioning member is a second body section One end away from the first body section The positioning member has a cross-sectional area smaller than that of the second main body section. The aerosol-generating substrate is covered by the positioning member through the first through-hole, and the free end of the positioning member abuts against the heating member. In this manner, a step structure is formed between the first main body section, the second main body section and the positioning member, and the aerosol-generating substrate is covered by the positioning member, thereby achieving orderly and tightly connected connections between the second main body section, the positioning member and the aerosol-generating substrate.

[0039] In any of the above technical solutions, the first gas path passes through the first body section, the second body section, the positioning member and the heating member.

[0040] In this technical solution, the first gas path passes through the first body section, the second body section, the positioning member and the heating member. During inhalation, air enters the second gas path from the air inlet, passes through the path between the protrusions, and then directly enters the first gas path, ensuring smooth air flow.

[0041] In any of the above technical solutions, the heating member is provided with a plurality of second through-holes, and the plurality of second through-holes communicate with the first gas path.

[0042] In this technical solution, the heating element is provided with a plurality of second through-holes, which are connected to the first gas passage, so that during inhalation, the aerosol generated by the aerosol-generating substrate can directly enter the first gas passage through the second through-holes, thereby enhancing the atomization effect of the aerosol in the aerosol-generating substrate.

[0043] In any of the above technical solutions, the atomization module further includes an identification device disposed in the heating member, for feeding back an identification signal sensed by the RF transmitting device.

[0044] In this technical solution, the atomization module further includes an identification device, which is installed inside the heating member, and can feed back the identification signal sensed by the RF transmitter. This enhances the consistency of the atomization module and the microwave module when identifying each other, and provides an anti-counterfeiting function, making it difficult to crack and recycle. This is beneficial to the protection of market order and the legitimate rights and interests of consumers.

[0045] Specifically, the identification device feeds back an identification signal to the RF transmitting device in the microwave module. When the RF transmitting device receives the identification signal, it performs verification and matching. If the identification signal is successfully verified, the microwave module activates the heating function for the atomization module, but if the identification signal is unsuccessful, the microwave module does not activate the heating function for the atomization module. This enhances the consistency when the atomization module and the microwave module identify each other, thereby achieving the purpose of automatically identifying counterfeit atomization modules.

[0046] Specifically, the exterior of the identification device is covered with a high-temperature resistant insulating material to provide protection for the identification device, and the insulating material is one of insulating cotton, polyurethane foam, and polyamide.

[0047] In a second aspect, the present application provides an aerosol generating device, which includes an atomization module according to any one of the above technical solutions, and a microwave module for introducing microwaves into the atomization module.

[0048] The present application provides an aerosol generating device including an atomization module in any of the above technical solutions, and thus has all the beneficial effects of the above atomization module, which will not be discussed here one by one.

[0049] In addition, the aerosol generating device further includes a microwave module, which is used to introduce microwaves into the atomization module to heat the aerosol-generating substrate and generate an aerosol.

[0050] Specifically, the atomization module is disposable and removably installed in the aerosol generating device, so that it can be discarded after inhalation, does not require cleaning, and is easy to replace, ensuring simplicity in use.

[0051] Specifically, the frequency band of microwave heating is 300 MHz to 300 GHz, and preferably 915 MHz and 2450 MHz.

[0052] The aerosol generating device based on the above technical solution in this application may further have the following additional technical features:

[0053] The aerosol generating device further includes an RF transmitting device capable of receiving an identification signal fed back from the identification device and used to verify the atomization module, and a power storage device electrically connected to the microwave module and the RF transmitting device and used to supply electricity to the microwave module and the RF transmitting device.

[0054] In this technical solution, the aerosol generating device further includes an RF transmitter and a power storage device. The power storage device is electrically connected to the microwave module and the RF transmitter, and is used to supply electricity to the microwave module and the RF transmitter. The RF transmitter can receive an identification signal fed back from the identification device, thereby verifying the atomization module.

[0055] Specifically, the RF transmitter receives the identification signal fed back from the identification device and performs verification and matching. If the identification signal is successfully verified, the microwave module supplies microwaves to the atomization module to heat the aerosol-generating substrate, but if the identification signal is unsuccessful, the microwave module does not supply microwaves to the atomization module. In this way, the consistency between the atomization module and the microwave module when identifying each other is strengthened, so that the purpose of automatically identifying counterfeit atomization modules is realized. This is beneficial to the protection of market order and the legitimate rights and interests of consumers.

[0056] Additional aspects and advantages of the present application will be set forth in part in the description that follows, and in part will be apparent from, and may be learned by, the practice of the present application.

[0059] In order to make the above objects, features and advantages of the present application more clearly understandable, the present application will be described in more detail below in combination with drawings and specific embodiments. It should be noted that, if not inconsistent, the embodiments and features of the present application may be combined with each other.

[0060] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be implemented in other ways different from those described herein, and therefore the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0061] Hereinafter, atomization modules and aerosol generating devices provided according to some embodiments of the present application will be described with reference to FIGS. 1 to 6. FIG.

[0062] As shown in FIGS. 1 and 2, a first embodiment of the present application provides an atomization module including a first housing 102, a second housing 106 and an aerosol generation module 108.

[0063] In this embodiment, as shown in FIG. 2, a first gas path 104 is provided through the inside of the first housing 102. The second housing 106 has a cavity structure with one open end. The second housing 106 is provided to cover at least a part of the outside of the first housing 102 through the opening, and is connected to the first housing 102. A second gas path 126 is formed between the first housing 102 and the second housing 106. The second gas path 126 is connected to the first gas path 104. This forms an intake gas path that is connected to the inside of the atomization module, ensuring air flow inside the atomization module during inhalation.

[0064] In this embodiment, as shown in Figs. 2 and 4, the second housing 106 has a cavity structure with one end open, and the aerosol generating module 108 is installed in the second housing 106. By covering the first housing 102 with the second housing 106, the aerosol generating module 108 is placed in a relatively sealed environment. This ensures that the aerosol generating module 108 receives heat uniformly, thereby improving the utilization rate of the aerosol generating module 108. In addition, the atomizing module provided in this application does not need to be equipped with components such as a conductive rod, a heating tip, or a heating needle. This avoids the problem that these components are inserted into the atomizing module and stick to the aerosol generating module 108, making cleaning difficult. In addition, the bottom of the atomizing module is installed in a sealed state, so that the aerosol generating device in which the atomizing module is installed will not be contaminated after the atomizing module is installed in the aerosol generating device. This extends the service life of the aerosol generating device.

[0065] In a specific embodiment, the first housing 102 and the aerosol generation module 108 are in close contact with each other, which ensures the stability of the internal structure of the atomization module and ensures that air flows in the first gas path 104 during inhalation, preventing air from escaping from inside the atomization module.

[0066] In a specific embodiment, the first and second housings are connected by an engagement groove to prevent the second housing from slipping off.

[0067] In a specific embodiment, the first housing is one of a supporting paperboard tube, a polylactic acid material tube, a polytetrafluoroethylene tube, a synthetic resin tube, a protein material tube, a vegetable rubber-based material tube, or a cellulose derivative material tube.

[0068] In a specific embodiment, the first housing 102 and the second housing 106 are made of a low dielectric loss material that has a certain strength and can fix a shape. Specifically, the first housing 102 and the second housing 106 can be made of one of a paperboard tube, a polylactic acid material, a polytetrafluoroethylene, a synthetic resin, a chemical fiber-based product, a nonwoven fabric, a ceramic plate, a PEEK material, and glass.

[0069] In a specific embodiment, the length of the atomization module is 30 to 70 mm, preferably 40 to 50 mm. Specifically, the length of the atomization module may be 40 mm, 45 mm, 50 mm, etc., but is not specifically limited here.

[0070] In this way, the atomization module provided in the present application has a connected inhalation gas path formed therein, so that the air flow inside the atomization module during inhalation is guaranteed. In addition, the second housing 106 has a cavity structure with one end open so that the inside of the atomization module is in a relatively sealed environment. This ensures that the aerosol-generating module 108 receives heat uniformly, so that the utilization rate of the aerosol-generating module 108 is improved. In addition, the atomization module provided in the present application does not need to be equipped with components such as a conductive rod, a heating tip, or a heating needle. This avoids the problem that these components are inserted into the atomization module and stick to the aerosol-generating module 108, making cleaning difficult. In addition, the bottom of the atomization module is installed in a sealed state, so that the aerosol-generating device in which the atomization module is installed will not be contaminated after the atomization module is installed in the aerosol-generating device. This extends the service life of the aerosol-generating device.

[0071] The second embodiment of the present application provides an atomization module. Based on the first embodiment, further, as shown in Figures 1 and 2, the first housing 102 includes a first body section 110 and a second body section 112.

[0072] 2 and 3, in this embodiment, the second body section 112 is connected to the end of the first body section 110, and the second housing 106 is covered on the outside of the second body section 112. A first pitch is provided between the second housing 106 and the second body section 112. A second pitch is provided between the second housing 106 and the end of the second body section 112. The height of the second housing 106 is lower than the end of the second body section 112.

[0073] 1 and 2, in this embodiment, the first pitch between the second housing 106 and the second body section 112 is used to form the second gas path 126, and the second pitch between the second housing 106 and the end of the second body section 112 is used to form the air inlet 124 of the second gas path 126. During the suction process, air outside the nebulization module enters the second gas path 126 through the air inlet 124 and then enters the inside of the nebulization module, so that the air flow inside the nebulization module is guaranteed.

[0074] In a specific embodiment, the outer diameter of the first body section 110 and the outer diameter of the second housing 106 are equal or approximately equal. The outer diameter of the first body section 110 is 6 to 20 mm, and preferably 8 to 10 mm. Specifically, the outer diameter of the first body section 110 may be 8 mm, 9 mm, 10 mm, etc., but is not specifically limited here.

[0075] In a specific embodiment, the outer diameter of the second main body section 112 is slightly smaller than the inner diameter of the second housing 106. The outer diameter of the second main body section 112 is 4 to 18 mm, and preferably 7 to 8.5 mm. The inner diameter of the second housing 106 is 7.5 to 19 mm, and preferably 7.5 to 9 mm. Specifically, the outer diameter of the second main body section 112 may be 7 mm, 7.5 mm, 8 mm, 8.5 mm, etc., and the inner diameter of the second housing 106 may be 7.5 mm, 8 mm, 8.5 mm, 9 mm, etc., but is not specifically limited here.

[0076] In addition, the atomization module provided in this embodiment has all the beneficial effects of the atomization module of the first embodiment. The inside of the atomization module is provided with a communicating passage, so that the air flows smoothly. In addition, the inside of the atomization module is in a relatively sealed environment, so that the uniformity of the heat received by the aerosol-generating module 108 is guaranteed, so that the utilization rate of the aerosol-generating module 108 is improved. In addition, the atomization module does not need to be provided with components such as a conductive rod, a heating tip or a heating needle. Therefore, the problem that these components are inserted into the atomization module and stick to the aerosol-generating module 108, which makes cleaning difficult, is avoided. In addition, the contamination of the aerosol generating device in which the atomization module is installed is prevented, so that the service life of the aerosol generating device is extended, which will not be described in detail here.

[0077] The third embodiment of the present application provides an atomization module. Based on the second embodiment, a receiving space is formed between the second body section 112 and the second housing 106, as shown in FIG. 2. In addition, the atomization module further includes a plurality of protrusions 128.

[0078] In this embodiment, as shown in FIG. 2, the aerosol generating module 108 and the multiple protrusions 128 are both installed in the accommodation space. The multiple protrusions 128 are installed on the bottom wall of the second housing 106 at intervals. This allows the multiple protrusions 128 to support the aerosol generating module 108. Since the multiple protrusions 128 are installed on the bottom wall of the second housing 106 at intervals, a path connecting the second gas path 126 and the first gas path 104 can be formed between the second housing 106 and the aerosol generating module 108. As a result, a connected suction path is formed inside the atomization module, ensuring the flow of air inside the atomization module during inhalation, and reducing resistance during inhalation.

[0079] In addition, the atomization module provided in this embodiment has all the beneficial effects of the atomization module of the second embodiment, which will not be discussed here one by one.

[0080] The fourth embodiment of the present application provides an atomization module. Based on the first to third embodiments, the aerosol-generating module 108 further includes an aerosol-generating substrate 114 and a heating element 118, as shown in FIG.

[0081] 2 and 5, in this embodiment, the aerosol-generating substrate 114 is structured with a first through-hole 116, and the heating member 118 is disposed within the first through-hole 116. In use, the heating member 118 absorbs microwaves and uses the microwaves to heat the aerosol-generating substrate 114, thereby generating an aerosol in the aerosol-generating substrate.

[0082] 2, the heating element 118 is disposed in the first through-hole 116 of the aerosol-generating substrate 114. In this way, when the aerosol-generating substrate 114 is heated using microwaves, even the aerosol-generating substrate 114 located at the periphery can be located in a strong microwave field. This ensures that the aerosol-generating substrate 114 at the periphery receives sufficient heat, thereby ensuring that the entire aerosol-generating substrate 114 receives uniform heat, thereby enhancing the atomization effect of the aerosol in the aerosol-generating substrate 114 and improving the utilization rate of the aerosol-generating substrate 114.

[0083] In a specific embodiment, the main raw material for preparing the aerosol-generating substrate 114 is tobacco leaves or herbs, and the form of the aerosol-generating substrate 114 includes granules, sheets, powdery pieces, threads, pastes, crepes, porous aerogels, and capsules.

[0084] In a specific embodiment, the aerosol-generating substrate 114 Outside diameterThe diameter of the aerosol-generating substrate 114 is 4 to 17 mm, preferably 5 to 8 mm. The height of the aerosol-generating substrate 114 is 6 to 25 mm, preferably 8 to 12 mm. Specifically, the diameter of the aerosol-generating substrate 114 may be 5 mm, 6 mm, 7 mm, 8 mm, etc., and the height of the aerosol-generating substrate 114 may be 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, etc., but these will not be specifically discussed here.

[0085] In a specific embodiment, the heating element 118 is a microwave absorbing material with relatively excellent high temperature resistance, and has the characteristics of good impedance matching, wide bandwidth, thin matching thickness, light mass, and strong absorption capacity, thereby enhancing the aerosol atomization effect in the aerosol-generating substrate 114.

During inhalation, air enters the second gas path 126 from the air inlet 124 at the open end of the second housing 106, and after traveling a preset distance, passes through the aerosol-generating substrate 114 and flows into the first gas path 104 together with the aerosol. Also, leakage of the aerosol from the air inlet 124 can be prevented.

[0090] In addition, the atomization module provided in this embodiment has all the beneficial effects of the atomization module of the fourth embodiment, which will not be discussed here one by one.

[0092] 2 and 3, in this embodiment, the positioning member 120 is disposed at the end of the second body section 112. The cross-sectional area of ​​the positioning member 120 is smaller than that of the second body section 112. The aerosol-generating substrate 114 is covered by the positioning member 120 through the first through-hole 116. The free end of the positioning member 120 abuts against the heating member 118. In this manner, a step structure is formed between the first body section 110, the second body section 112 and the positioning member 120, and the aerosol-generating substrate 114 is covered by the positioning member 120, thereby realizing orderly and tightly connection between the second body section 112, the positioning member 120 and the aerosol-generating substrate 114.

[0093] 2 and 3, in this embodiment, the first gas path 104 penetrates the first body section 110, the second body section 112, the positioning member 120, and the heating member 118. During inhalation, air enters the second gas path 126 from the air inlet 124, passes through the path between the multiple protrusions 128, and then directly enters the first gas path 104, ensuring smooth air flow.

[0094] In addition, the atomization module provided in this embodiment has all the beneficial effects of the atomization module of the fourth embodiment, which will not be discussed here one by one.

[0095] The seventh embodiment of the present application provides an atomization module. Based on the fourth embodiment, the heating member 118 further includes a plurality of second through-holes 122, as shown in FIG. 6. The plurality of second through-holes 122 communicate with the first gas passage 104.

[0096] 6, the heating member 118 is provided with a plurality of second through-holes 122. Moreover, the second through-holes 122 communicate with the first gas path 104. In this way, during inhalation, the aerosol generated by the aerosol-generating substrate 114 can directly enter the first gas path 104 through the second through-holes 122, thereby enhancing the atomization effect of the aerosol in the aerosol-generating substrate 114.

[0097] In addition, the atomization module provided in this embodiment has all the beneficial effects of the atomization module of the fourth embodiment, which will not be discussed here one by one.

[0098] The eighth embodiment of the present application provides an atomization module, which is based on the fourth embodiment, further comprising an identification device (not shown).

[0099] In this embodiment, the identification device is installed inside the heating element 118. And the identification device can feed back the identification signal sensed by the RF transmitter. In this way, the consistency of the atomization module and the microwave module when identifying each other can be strengthened, and the anti-counterfeiting function is provided, so that cracking and recycling are difficult. This is favorable to protecting the market order and the legitimate rights and interests of consumers.

[0100] In a specific embodiment, the identification device transmits an identification signal to an RF transmitter in the microwave module. When the RF transmitter receives the identification signal, it performs verification and matching. If the identification signal is verified successfully, the microwave module activates a heating function for the atomization module, but if the identification signal is not verified successfully, the microwave module does not activate a heating function for the atomization module. This enhances the consistency when the atomization module and the microwave module identify each other, thereby achieving the purpose of automatically identifying counterfeit atomization modules. In a specific embodiment, the outside of the identification device is covered with a high-temperature resistant insulating material to provide protection for the identification device. The insulating material is one of insulating cotton, polyurethane foam, and polyamide.

[0101] In addition, the atomization module provided in this embodiment has all the beneficial effects of the atomization module of the fourth embodiment, which will not be discussed here one by one.

[0104] In addition, in this embodiment, the aerosol generating device further includes a microwave module, an RF transmitter, and a power storage device. The microwave module is used to introduce microwaves into the atomization module to heat the aerosol generating substrate 114 and generate aerosol. The power storage device is electrically connected to the microwave module and the RF transmitter, and is used to supply electricity to the microwave module and the RF transmitter. The RF transmitter can receive an identification signal fed back from the identification device, and verify and match the atomization module to achieve anti-counterfeiting effect.

[0105] In a specific embodiment, the RF transmitting device receives the identification signal fed back from the identification device and performs verification and matching. If the identification signal is verified successfully, the microwave module supplies microwaves to the atomization module to heat the aerosol-generating substrate 114, but if the identification signal is not verified successfully, the microwave module does not supply microwaves to the atomization module. In this way, the consistency between the atomization module and the microwave module when identifying each other is enhanced, so that the purpose of automatically identifying counterfeit atomization modules is realized. This is beneficial to the protection of market order and the legitimate rights and interests of consumers.

[0106] In a specific embodiment, the frequency band of microwave heating is 300 MHz to 300 GHz, preferably 915 MHz and 2450 MHz.

[0107] In a specific embodiment, the nebulization module is disposable and removably installed in the aerosol generating device, so that it can be discarded after use, does not require cleaning, and is easy to replace, ensuring simplicity of use.

[0108] Therefore, the aerosol generating device provided in the present application can realize uniform heating of the aerosol-generating substrate 114. In addition, the counterfeit atomization module can be automatically identified, which is advantageous for protecting the market order and the legitimate rights and interests of consumers.
