Description

[Technical Field]

[0001] This application is in the field of electronic atomization, and more particularly, relates to aerosol generating devices. [Background technology]

[0002] A heat not burning (HNB) device is an electronic device that heats an aerosol-generating substrate (treated plant leaf product) without burning it. By heating the aerosol-generating substrate to a high temperature that can generate aerosols but does not result in combustion, the aerosol-generating substrate can generate the desired aerosol without burning.

[0003] Currently, commercially available HNB devices mainly use a resistance heating method, i.e., a central heating tip or Center heating needle Heating is achieved by inserting a substance, such as a substance, into the aerosol-generating substrate from its center. Such devices require preheating before use, resulting in long standby times and the inability to freely start and stop inhalation. Furthermore, the aerosol-generating substrate carbonizes unevenly, resulting in insufficient baking, resulting in low utilization. Furthermore, the heating tip of an HNB device easily stains the aerosol-generating substrate removal device and the heating tip base, making cleaning difficult. Furthermore, the temperature of the aerosol-generating substrate in contact with the heating element can become too high, causing partial decomposition and the release of substances harmful to the human body. Therefore, microwave heating technology is gradually replacing resistance heating. Microwave heating technology is efficient, rapid, selective, and has no heating delay, and it can only heat materials with specific dielectric properties. The practical advantages of using microwave atomization include the following:

[0004] a. Microwave heating is radiation heating, not heat transfer, so it can be inhaled and stopped immediately.

[0005] b. Since there is no heating tip, there is no problem of tip breakage or cleaning of the heating tip.

[0006] c. The utilization rate of the aerosol-generating substrate is high, and the draw is more consistent with that of a cigarette.

[0007] However, conventional microwave-heated HNB devices cannot immediately control the microwave module to stop working after the user stops inhaling, so they require electrical energy and Aerosol-generating substrate This will result in waste. Summary of the Invention [Problem to be solved by the invention]

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

[0009] Therefore, the present application provides an aerosol generating device.

[0010] In view of the above, the present application provides an aerosol generating device including: a housing including a resonant cavity; a microwave module provided in the housing and configured to supply microwaves into the resonant cavity; a mounting portion provided in the housing and at least a portion of which is located within the resonant cavity, the mounting portion including an atomization chamber, the atomization chamber being used to accommodate an aerosol-generating substrate; and a pressure sensor provided in the housing and located outside the resonant cavity, the pressure sensor having a collection end communicating with the atomization chamber and being used to collect air pressure values ​​within the atomization chamber.

[0011] The aerosol generating device provided by the present application includes a housing, a microwave module, a mounting part, and a pressure sensor. A resonant cavity is provided within the housing. The microwave output end of the microwave module is connected to the resonant cavity, and microwaves generated by the microwave module are supplied into the resonant cavity. The mounting part is provided within the housing. An atomization chamber is provided inside the mounting part. The atomization chamber is used to accommodate an aerosol-generating substrate. The microwave module supplies microwaves into the resonant cavity and transmits them to the mounting part via the resonant cavity, thereby microwave-heating the aerosol-generating substrate in the atomization chamber.

[0012] The mounting portion separates the resonant cavity from the atomization chamber, thereby preventing liquid or solid debris generated after atomization of the aerosol-generating substrate in the atomization chamber from entering the resonant cavity, thereby preventing the aerosol generator from malfunctioning due to debris entering the resonant cavity.

[0013] The aerosol generating device further includes a pressure sensor. The collection end of the pressure sensor is in communication with the atomization chamber. The pressure sensor can collect the air pressure value within the atomization chamber. By providing the pressure sensor in the housing and positioning the pressure sensor outside the resonant cavity, the pressure sensor is not affected by microwaves transmitted within the resonant cavity. By collecting changes in the air pressure value within the atomization chamber using the pressure sensor, it is possible to detect whether the aerosol generating device is in an inhalation state based on the changes in the air pressure value within the atomization chamber. Then, the operation of the microwave module is controlled based on the inhalation state of the aerosol generating device.

[0014] In some embodiments, when it is detected that the aerosol-generating device is in an inhalation state, the microwave module is operated to atomize the aerosol-generating substrate in the atomization chamber by microwave heating, and when the aerosol-generating device is not in an inhalation state, the microwave module is stopped to prevent the aerosol-generating substrate in the atomization chamber from being continuously atomized by heating.

[0015] In some other embodiments, when the aerosol generating device receives a preheating control command in an activated state, the aerosol generating device controls the microwave module to operate at a first power until the indoor temperature value of the atomization chamber falls within a set temperature range, thereby maintaining the indoor temperature value within the set temperature range and thereby achieving a preheating effect on the aerosol-generating substrate in the atomization chamber. aerosol generator Detect whether the device is in an inhalation state or not, aerosol generator The first power is adjusted based on the inhalation state of the aerosol generator. Specifically, when it is detected that the aerosol generator is in an inhalation state, the microwave module is operated at a second power, thereby controlling the temperature in the atomization chamber to rapidly increase. As a result, the aerosol-generating substrate is rapidly heated and atomized, generating an aerosol. Note that the second power is greater than the first power. On the other hand, when it is detected that the aerosol generator is not in an inhalation state, the microwave module is controlled to continue operating at the first power, thereby continuing to preheat the aerosol-generating substrate.

[0016] In the present application, the pressure sensor collects the air pressure value in the atomization chamber to detect whether the aerosol generator is in an inhalation state, and controls the operation of the microwave module based on the inhalation state. This allows the microwave module to be immediately controlled to stop operation after the user stops inhaling, thereby avoiding waste of electrical energy and aerosol-generating substrates. aerosol generator Since the aerosol-generating substrate is preheated when not inhaled, it can be rapidly heated to the atomization temperature when inhaled, thereby reducing energy consumption and improving the atomization efficiency of the aerosol-generating substrate, and further improving the degree of atomization of the aerosol-generating substrate, thereby improving the user experience.

[0017] In addition, the aerosol generating device in the above technical solution provided by the present application may further have the following additional technical features:

[0018] In a possible design, the mounting part comprises a base body in which the atomization chamber is provided, and a guide member having one end connected to the base body and the other end connected to the collecting end of the pressure sensor.

[0019] In this design, the mounting portion includes a base body and a guide member. The base body is disposed within the housing. The base body and the atomization chamber surround and form a resonant cavity. The guide member is inserted into the housing. One end of the guide member is connected to the base body and communicates with the atomization chamber. The other end of the guide member extends to the outside of the housing and is connected to the pressure sensor. The guide member connects the atomization chamber to the pressure sensor outside the housing, allowing the pressure sensor to directly collect the pressure value inside the atomization chamber.

[0020] In a possible design, the guide member includes a first tube integrally molded to the base body and a second tube provided in the housing, the first end of which passes through the housing and is connected to the first tube, and the second end of which is connected to the pressure sensor, the collection end of the pressure sensor being located within the second tube.

[0021] In this design, the guide member includes a first tube and a second tube. The first tube is in communication with the base body. The second tube is provided on the side wall of the housing. The second tube penetrates the housing and connects to the first tube. One end of the second tube located outside the housing is connected to the pressure sensor. By providing the guide member so that the first tube and the second tube are connected, the assembly process of the aerosol generator can be simplified. It is also convenient for disassembling and cleaning the mounting part separately.

[0022] The first tube is integrally molded with the base body, further reducing the number of assembly steps, and the second tube is attached to the housing by a fastening member, which can be a screw, rivet, or other fastening member.

[0023] The assembly steps for the guide member and the mounting part include: inserting the base body, which is integrally formed with the first pipe, into the housing; then inserting the second pipe into the side wall of the housing and connecting the second pipe to the first pipe; thereby connecting the first and second pipes to the atomization chamber in the base body and ensuring a sealing performance for the connection between the first and second pipes; and finally, fastening the second pipe to the side wall of the housing with a fastening member to complete the assembly process for the guide member and the mounting part. By providing the first pipe and the second pipe on the inside and outside of the housing, respectively, and connecting the first pipe and the second pipe to each other, it is possible to simplify the assembly steps for the guide member while ensuring the sealing performance of the guide member.

[0024] In one possible design, the mounting portion further includes an opening at one end of the base body, the opening communicating with the atomization chamber, and used to allow the aerosol-generating substrate to enter the atomization chamber.

[0025] In this design, the mounting portion further includes an opening at one end of the base body, the opening facing the exterior of the housing, and communicating with the atomization chamber for loading the aerosol-generating substrate into the atomization chamber through the opening.

[0026] As can be seen, the aerosol-generating substrate is provided with an inhalation portion that protrudes from the atomization chamber through an opening, allowing a user to inhale the aerosol-generating substrate.

[0027] In one possible design, the aerosol generating device further includes a first through-hole provided in the housing, and the resonant cavity communicates with the outside of the chamber through the first through-hole. The mounting part further includes a second through-hole provided in the base body, and the atomization chamber communicates with the resonant cavity through the second through-hole.

[0028] In this design, the aerosol generator includes a first through-hole and a second through-hole. The first through-hole is provided in the housing and connects the resonant cavity to the outside of the housing. The second through-hole is provided in the base and connects the resonant cavity to the atomization chamber. When a user inhales through the inhalation port of the aerosol-generating substrate, gas outside the housing passes through the first through-hole, the resonant cavity, the second through-hole, the atomization chamber, and the aerosol-generating substrate in that order. When the aerosol-generating substrate is heated, precipitates mix with the gas to form an aerosol, which is then discharged through the inhalation port. This creates a gas flow path, allowing air from outside the housing to continuously replenish the atomization chamber during inhalation of the aerosol-generating substrate, ensuring sufficient atomization of the aerosol-generating substrate. This also prevents excessively high resistance to airflow from the aerosol-generating substrate, improving the user experience.

[0029] In a possible design, the mounting portion further includes at least two protrusions provided on the inner wall of the atomization chamber. The at least two protrusions protrude from the inner wall of the atomization chamber. A gap is provided between two adjacent protrusions of the at least two protrusions. The at least two protrusions are used to secure the aerosol-generating substrate.

[0030] In this design, the mounting portion further includes at least two protrusions provided on the inner wall of the atomization chamber. The at least two protrusions are capable of securing the aerosol-generating substrate. When the aerosol-generating substrate is inserted into the atomization chamber through the opening, the at least two protrusions abut against the outer wall of the aerosol-generating substrate, thereby securing the aerosol-generating substrate. This prevents the aerosol-generating substrate from slipping out of the atomization chamber.

[0031] Adjacent two of the at least two protrusions are spaced apart, and an airflow path is formed by the gap between the adjacent two protrusions and the air gap between the aerosol-generating substrate and the side wall of the atomization chamber.

[0032] When a user inhales through the inhalation port of the aerosol-generating substrate, gas outside the housing passes through the gap between the two adjacent protrusions, the gap between the aerosol-generating substrate and the sidewall of the atomization chamber, and then through the aerosol-generating substrate. When the aerosol-generating substrate is heated, precipitates mix with the gas to form an aerosol, which is then expelled from the inhalation port. This allows air outside the housing to be constantly replenished into the atomization chamber during the inhalation process, ensuring sufficient atomization of the aerosol-generating substrate. This also prevents excessive resistance to inhalation of the aerosol-generating substrate due to insufficient airflow, improving the user experience.

[0033] In a possible design, at least two protrusions are located on the inner wall of the atomization chamber adjacent to the opening, and the at least two protrusions are uniformly distributed around the circumference of the atomization chamber.

[0034] In this design, at least two protrusions are uniformly distributed along the axial direction of the atomization chamber. The uniformly distributed protrusions can effectively secure the aerosol-generating substrate, preventing it from falling out of the atomization chamber during inhalation. Furthermore, while the aerosol-generating substrate generates some dust during inhalation, the at least two protrusions are located at one end adjacent to the opening, allowing the user to easily clean the dust. This prevents dust from clogging the gaps between the protrusions, improving the operational stability of the aerosol generator.

[0035] In a possible design, the mounting portion further includes a groove, which is provided on the inner wall of the atomization chamber and extends along the centerline of the atomization chamber.

[0036] In this design, the mounting part further includes a groove formed in the inner wall of the atomization chamber. After the aerosol-generating substrate is inserted into the atomization chamber through the opening, the aerosol-generating substrate comes into contact with the inner wall of the atomization chamber, and the friction between the inner wall of the atomization chamber and the aerosol-generating substrate prevents the aerosol-generating substrate from falling out of the atomization chamber.

[0037] When a user inhales through the inhalation port of the aerosol-generating substrate, gas outside the housing passes through the groove and then the aerosol-generating substrate. When the aerosol-generating substrate is heated, precipitates mix with the gas to form an aerosol, which is then expelled from the inhalation port. This allows air outside the housing to be constantly replenished into the atomization chamber during the inhalation process, ensuring sufficient atomization of the aerosol-generating substrate. This also prevents excessive resistance to inhalation of the aerosol-generating substrate due to insufficient airflow, improving the user experience.

[0038] In a possible design, the number of grooves is at least two, and the at least two grooves are uniformly distributed along the circumferential direction of the atomization chamber.

[0039] In this design, the grooves are uniformly distributed on the inner peripheral sidewall of the atomization chamber, allowing the external air to uniformly contact the aerosol-generating substrate, so that the precipitates on the aerosol-generating substrate can be thoroughly mixed with the air to form an aerosol, thereby improving the atomization efficiency of the aerosol-generating substrate.

[0040] As can be seen, the suction resistance of the aerosol generating device can be adjusted by rationally setting the number and inner diameter of the grooves.

[0041] In one possible design, the attachment further includes a spacer disposed in the atomization chamber, the spacer dividing the atomization chamber into a first chamber and a second chamber, the first chamber being in communication with the second chamber, the first chamber being used to contain the aerosol-generating substrate.

[0042] In this design, the attachment further includes a spacer disposed within the atomization chamber, dividing the atomization chamber into a first chamber and a second chamber that communicate with each other, the first chamber being used to contain the aerosol-generating substrate, and the second chamber communicating with the air outside the atomization chamber.

[0043] When a user inhales through the inhalation port of the aerosol-generating substrate, air from outside the housing passes through the second chamber, the first chamber, and the aerosol-generating substrate in that order. That is, the air passes through the second chamber, enters the first chamber, and comes into contact with the aerosol-generating substrate. When the aerosol-generating substrate is heated, precipitates mix with the gas to form an aerosol, which is then discharged through the inhalation port. This allows air from outside the housing to be constantly replenished into the atomization chamber during the inhalation process of the aerosol-generating substrate, ensuring sufficient atomization of the aerosol-generating substrate. This also prevents excessive resistance to inhalation of the aerosol-generating substrate due to insufficient airflow, improving the user experience.

[0044] In a possible design, the first and second chambers are distributed in a coaxial annular fashion, with the second chamber located outside the first chamber.

[0045] In this design, the second chamber is annularly disposed outside the first chamber, so that the air passes through the second chamber and then uniformly enters the first chamber from the outside. This allows the external air to uniformly contact the aerosol-generating substrate, allowing the deposits on the aerosol-generating substrate to mix well with the air and form an aerosol. This improves the atomization efficiency of the aerosol-generating substrate.

[0046] In a possible design, the mounting portion further includes a third through-hole provided in the spacer, the third through-hole being located at one end of the spacer that is connected to the bottom wall of the atomization chamber.

[0047] In this design, the mounting portion further includes a third through-hole, which is provided in the spacer and connects the first chamber with the second chamber.

[0048] In a possible design, the mounting portion further includes a support portion provided on the bottom wall of the atomization chamber, the support portion protruding from the bottom wall of the atomization chamber.

[0049] In this design, the mounting portion further includes a support portion provided on the bottom wall of the atomization chamber. The support portion supports the aerosol-generating substrate, thereby creating a gap between the aerosol-generating substrate and the bottom wall of the atomization chamber. This allows air entering the atomization chamber from the outside to come into contact with the bottom end of the aerosol-generating substrate, further improving the mixing effect between the air and the precipitate formed when the aerosol-generating substrate is heated. This allows the precipitate on the aerosol-generating substrate to be sufficiently mixed with the air to form an aerosol, thereby improving the atomization effect of the aerosol-generating substrate.

[0050] In one possible design, the housing includes a body and an end cover removably connected to the body, with the mounting portion inserted into the end cover, and the end cover and body enclosing a resonant cavity.

[0051] In this design, the housing includes a main body and an end cover. The attachment portion is provided on the end cover, and the end cover is removably connected to the main body. This allows users to easily remove the end cover and disassemble and clean the attachment portion separately, thereby avoiding damage caused by water intrusion when cleaning the entire aerosol generating device.

[0052] In a possible design, the aerosol generating device further comprises a resonant rod disposed within the resonant cavity, the first end of the resonant rod being connected to the bottom wall of the resonant cavity and the second end of the resonant rod being connected to the mounting portion. To respond It will be established.

[0053] In this design, a resonant rod is used to resonate microwaves. The first end of the resonant rod is connected to the bottom wall of the resonant cavity, and the second end of the resonant rod is connected to the mounting part. To respond The microwave module supplies microwaves into the resonant cavity and the microwaves are transmitted from the first end to the second end of the resonant rod, thereby microwave-heating the aerosol-generating substrate in the atomization chamber of the mounting portion.

[0054] Since the atomization chamber and the resonant cavity are isolated by the mounting portion, liquid or solid debris generated after atomization of the aerosol-generating substrate in the atomization chamber can be prevented from entering the resonant cavity, thereby preventing the microwave module from being damaged by debris entering the resonant cavity.

[0055] In some embodiments, the inner walls of the resonant cavity and the resonant rods are made of a conductive material, which can be selected from metallic materials such as gold, copper, and silver.

[0056] In some embodiments, the inner wall of the resonant cavity and the outer wall of the resonant rod are provided with a conductive coating layer, which may be selected from metal coating layers such as gold-plated layers, copper-plated layers, silver-plated layers, etc.

[0057] In these embodiments, the resonant cavity and the resonant rod are made of a metal with high stability and excellent conductivity, which not only prevents microwaves from leaking out but also prevents the inner wall of the resonant cavity and the resonant rod from rusting.

[0058] In some embodiments, the portion of the mounting portion located within the resonant cavity is made of a low dielectric loss material, such as a PTFE (polytetrafluoroethylene) material, a glass material, or a ceramic material, which allows microwaves to be transmitted to the atomization chamber within the mounting portion, thereby heating the aerosol-generating substrate within the atomization chamber and generating an aerosol.

[0059] In some embodiments, the mount is removably connected to the housing.

[0060] In these embodiments, the nebulization chamber for containing the aerosol-generating substrate is located within the mounting portion, thereby improving the user experience by allowing the nebulization chamber to be disassembled and cleaned independently by removing the mounting portion.

[0061] In a possible design, the resonating rod is spaced apart from the mounting portion.

[0062] This design provides a gap between the resonating rod and the mounting part, which prevents the resonating rod from being pressed during the process of assembling the mounting part to the housing, thereby reducing the requirements for production and assembly precision of the resonating rod and mounting part.

[0063] In a possible design, the aerosol generating device further comprises a fixing part provided on the mounting part and positioned within the resonant cavity, the fixing part comprising a position limiting chamber, and at least a portion of the resonant rod being positioned within the position limiting chamber.

[0064] In this design, the aerosol generator further includes a fixing part provided on the mounting part. A position restriction chamber is provided within the fixing part, and at least a portion of the resonator rod is positioned within the position restriction chamber. The fixing part fixes the resonator rod within the position restriction chamber, thereby providing a certain degree of vibration isolation for the resonator rod. This prevents the resonator rod from falling out due to vibration.

[0065] In some embodiments, the fixed portion and the mounting portion are integrally molded.

[0066] In these embodiments, the fixed portion and the mounting portion, which are integrally formed, have high bonding strength, and therefore the stabilization effect of the fixed portion on the resonating rod is improved.

[0067] In a possible design, the axis of the atomization chamber and the axis of the resonating rod are coaxial.

[0068] In this design, the atomization chamber and the resonator rod are arranged coaxially, ensuring that the microwaves transmitted to the atomization chamber via the resonator rod are transmitted to the center of the atomization chamber, thereby improving the uniformity of heating of the aerosol-generating substrate in the atomization chamber and avoiding uneven heating of the aerosol-generating substrate caused by microwave concentration in the atomization chamber, thereby further improving the atomization effect of the aerosol-generating substrate.

[0069] In a possible design, the microwave module includes a microwave introduction section provided on a side wall of the housing and communicating with the resonant cavity, and a microwave source connected to the microwave introduction section, wherein microwaves output from the microwave introduction section are supplied to the resonant cavity via the microwave introduction section, and the microwaves are transmitted in a direction from the first end of the resonant rod to the second end of the resonant rod.

[0070] In this design, the microwave module includes a microwave emission source and a microwave introduction section. The microwave emission source is used to generate microwaves. The microwave introduction section, located on the side wall of the housing, is used to transport the microwaves generated by the microwave emission source into the resonant cavity. The microwaves are supplied to the resonant cavity via the microwave introduction section. The microwaves can then be transmitted in a direction from the first end of the resonant rod to the second end of the resonant rod. This allows the microwaves to directly act on the aerosol-generating substrate in the atomization chamber, thereby improving the atomization effect of the aerosol-generating substrate.

[0071] In a possible design, the microwave introduction section includes a first introduction member provided on a side wall of the housing and connected to the microwave emission source, and a second introduction member having a first end connected to the first introduction member, the second introduction member being located within the resonant cavity, and a second end facing the bottom wall of the resonant cavity.

[0072] In this design, the microwave introduction section includes a first introduction member and a second introduction member. The first introduction member is inserted into a side wall of the housing. A first end of the first introduction member is connected to a microwave emission source. Thus, microwaves generated by the microwave emission source enter the microwave introduction section from the first end of the first introduction member. A second end of the first introduction member is connected to a first end of the second introduction member. The second end of the second introduction member faces the bottom wall of the resonant cavity. After being transmitted via the first and second introduction members, the microwaves are transmitted from the bottom wall of the resonant cavity to the atomization chamber, where they atomize the aerosol-generating substrate in the atomization chamber by microwave heating.

[0073] The first introduction section is arranged coaxially with the microwave output end of the microwave emission source. The second introduction member has a horizontal introduction section and a vertical introduction section. The axis of the horizontal introduction section is parallel to the bottom wall of the resonant cavity, and the axis of the vertical introduction section is perpendicular to the bottom wall of the resonant cavity. The horizontal introduction section is connected to the vertical introduction section via a bent section. The horizontal introduction section is also arranged coaxially with the first introduction section. By providing the microwave introduction sections as described above, all of the microwaves generated by the microwave emission source can enter the resonant cavity and be transmitted within the resonant cavity by the resonant rod.

[0074] In a possible design, the aerosol generating device further comprises a recess in the bottom wall of the resonant cavity, the second end of the second introduction member being located within the recess.

[0075] In this design, aerosol generator The cavity further includes a recess, the recess being provided in the bottom wall of the resonant cavity, and the recess is connected to the second end of the second lead-in member. In response The second end of the second introduction member extends into the recessed portion, and the microwaves entering the resonant cavity can be transmitted from the second end to the first end of the resonant rod, thereby reducing energy loss during the microwave transmission process.

[0076] In one possible design, the microwave introduction section includes a third introduction member provided on a side wall of the housing, a first end of the third introduction member connected to the microwave source, and a second end of the third introduction member facing the resonant rod.

[0077] In this design, the microwave introduction section further includes a third introduction member. The third introduction member is arranged coaxially with the microwave output end of the microwave emission source. A first end of the third introduction member is connected to the microwave emission source, and a second end of the third introduction member faces the resonant rod. By arranging the third introduction member coaxially with the microwave output end of the microwave emission source and connecting the third introduction member to the resonant rod, microwaves are directly transmitted to the resonant rod. This allows all microwaves output from the microwave emission source to enter the resonant cavity.

[0080] In order to make the above-mentioned objects, features and advantages of the present application more clearly understood, 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.

[0081] In the following description, numerous specific details are set forth 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.

[0082] Hereinafter, with reference to FIGS. 1 to 10, a description will be given of a method for manufacturing a semiconductor device according to some embodiments of the present invention. aerosol generator This article describes:

[0083] As shown in FIGS. 1 and 3, one embodiment of the present application provides an aerosol generating device 100 including a housing 110, a microwave module 130, a mounting portion 140, and a pressure sensor 150.

[0084] The housing 110 contains a resonant cavity 120 .

[0085] The microwave module 130 is mounted on the housing 110. The microwave module 130 is used to supply microwaves into the resonant cavity 120.

[0086] Mounting portion 140 is provided on housing 110. At least a portion of mounting portion 140 is located within resonant cavity 120. Mounting portion 140 includes an atomization chamber 143. Atomization chamber 143 is used to accommodate an aerosol-generating substrate.

[0087] The pressure sensor 150 is mounted on the housing 110 and is located outside the resonant cavity 120. The collection end of the pressure sensor 150 communicates with the atomization chamber 143 and is used to collect the air pressure value within the atomization chamber 143.

[0088] The aerosol generating device 100 provided in this embodiment includes a housing 110, a microwave module 130, a mounting part 140, and a pressure sensor 150. A resonant cavity 120 is provided within the housing 110. A microwave output end of the microwave module 130 is connected to the resonant cavity 120, and microwaves generated by the microwave module 130 are supplied into the resonant cavity 120. The mounting part 140 is provided within the housing 110. An atomization chamber 143 is provided within the mounting part 140. The atomization chamber 143 is used to accommodate an aerosol-generating substrate. The microwave module 130 supplies microwaves into the resonant cavity 120, and the microwaves are transmitted to the mounting part 140 via the resonant cavity 120, thereby microwave-heating the aerosol-generating substrate in the atomization chamber 143.

[0089] The mounting portion 140 separates the resonant cavity 120 from the atomization chamber 143, thereby preventing liquid or solid debris generated after atomization of the aerosol-generating substrate in the atomization chamber 143 from entering the resonant cavity 120. This prevents the aerosol generating device 100 from breaking down due to debris entering the resonant cavity 120.

[0090] The aerosol generating device 100 further includes a pressure sensor 150. A collection end of the pressure sensor 150 is in communication with the atomization chamber 143. The pressure sensor 150 can collect the air pressure value within the atomization chamber 143. By providing the pressure sensor 150 in the housing 110 and positioning the pressure sensor 150 outside the resonant cavity 120, the pressure sensor 150 is not affected by microwaves transmitted within the resonant cavity 120. By collecting changes in the air pressure value within the atomization chamber 143 with the pressure sensor 150, it is possible to detect whether the aerosol generating device 100 is in an inhalation state based on the changes in the air pressure value within the atomization chamber 143. Then, the operation of the microwave module 130 is controlled based on the inhalation state of the aerosol generating device 100.

[0091] In some embodiments, when it is detected that the aerosol-generating device 100 is in an inhalation state, the microwave module 130 is operated to atomize the aerosol-generating substrate in the atomization chamber 143 by microwave heating. When the aerosol-generating device 100 is not in an inhalation state, the operation of the microwave module 130 is stopped to prevent the aerosol-generating substrate in the atomization chamber 143 from continuing to be atomized by heating.

[0092] In some other embodiments, when the aerosol generating device 100 receives a preheating control command in an activated state, it controls the microwave module 130 to operate at the first power until the room temperature value of the atomization chamber 143 falls within the range of the set temperature value. This maintains the room temperature value within the range of the set temperature value, thereby enabling the preheating effect on the aerosol-generating substrate in the atomization chamber 143 to be exerted. aerosol generator 100 detects whether or not the device is inhaling. aerosol generatorThe first power is adjusted based on the inhalation state of the aerosol-generating device 100. Specifically, when it is detected that the aerosol-generating device 100 is in the inhalation state, the microwave module 130 is operated at the second power, thereby controlling the temperature in the atomization chamber 143 to rapidly increase. As a result, the aerosol-generating substrate is rapidly heated and atomized, generating an aerosol. Note that the second power is greater than the first power. On the other hand, when it is detected that the aerosol-generating device 100 is not in the inhalation state, the microwave module 130 is controlled to continue operating at the first power, so as to continue preheating the aerosol-generating substrate.

[0093] In the present application, the pressure sensor 150 collects the air pressure value in the atomization chamber 143 to detect whether the aerosol generating device 100 is in an inhalation state, and controls the operation of the microwave module 130 based on the inhalation state. As a result, once the user stops inhaling, the microwave module 130 can be immediately controlled to stop operation, thereby avoiding waste of electrical energy and aerosol generating substrates. aerosol generator The aerosol-generating substrate 100 is preheated when not inhaled, allowing the substrate to be rapidly heated to the atomization temperature when inhaled, thereby reducing energy consumption and improving the atomization efficiency of the aerosol-generating substrate, and further improving the degree of atomization of the aerosol-generating substrate, thereby improving the user experience.

[0094] In addition, the aerosol generating device 100 in the above technical solution provided by the present application may further have the following additional technical features:

[0095] As shown in FIGS. 1 and 3, in any of the above embodiments, the mounting portion 140 includes a base body 141, a guide member 142, and an atomization chamber 143.

[0096] The atomization chamber 143 is provided in the base body 141 .

[0097] One end of the guide member 142 is connected to the base body 141 and communicates with the atomization chamber 143. The other end of the guide member 142 is connected to the collecting end of the pressure sensor 150.

[0098] In this embodiment, the mounting part 140 includes a base body 141 and a guide member 142. The base body 141 is disposed within the housing 110. The base body 141 and the atomization chamber 143 surround and define the resonant cavity 120. The guide member 142 is inserted into the housing 110. One end of the guide member 142 is connected to the base body 141 and communicates with the atomization chamber 143. The other end of the guide member 142 extends to the outside of the housing 110 and is connected to the pressure sensor 150. The guide member 142 communicates between the atomization chamber 143 and the pressure sensor 150 outside the housing 110, allowing the pressure sensor 150 to directly collect the pressure value within the atomization chamber 143.

[0099] As shown in FIG. 1, in either embodiment, guide member 142 includes a first tube 1422 and a second tube 1424 .

[0100] The first pipe member 1422 is integrally formed with the base body 141 .

[0101] A second tube 1424 is provided in the housing 110. A first end of the second tube 1424 passes through the housing 110 and connects to the first tube 1422. A second end of the second tube 1424 connects to the pressure sensor 150. The collection end of the pressure sensor 150 is located within the second tube 1424.

[0102] In this embodiment, the guide member 142 includes a first pipe 1422 and a second pipe 1424. The first pipe 1422 is in communication with the base body 141. The second pipe 1424 is provided on the side wall of the housing 110. The second pipe 1424 passes through the housing 110 and is connected to the first pipe 1422. One end of the second pipe 1424 located outside the housing 110 is connected to the pressure sensor 150. By providing the guide member 142 so that the first pipe 1422 and the second pipe 1424 are connected, the assembly process of the aerosol generation device 100 can be simplified. It is also convenient to disassemble and clean the mounting part 140 separately.

[0103] The first pipe member 1422 is provided so as to be integrally molded with the base body 141, further reducing the number of assembly steps. The second pipe member 1424 is attached to the housing 110 by a fixing member. The fixing member may be a fastening member such as a screw or a rivet.

[0104] The assembly steps of the guide member 142 and the mounting part 140 include the following: inserting the base body 141, on which the first pipe 1422 is integrally formed, into the housing 110; then, inserting the second pipe 1424 into the side wall of the housing 110, and connecting the second pipe 1424 to the first pipe 1422. This allows the first pipe 1422 and the second pipe 1424 to communicate with the atomization chamber 143 in the base body 141, and ensures a sealed connection between the first pipe 1422 and the second pipe 1424. Finally, fastening the second pipe 1424 to the side wall of the housing 110 with a fastener completes the assembly process of the guide member 142 and the mounting part 140. By providing a first pipe 1422 and a second pipe 1424 on the inside and outside of the housing 110, respectively, and connecting the first pipe 1422 and the second pipe 1424 to each other, it is possible to simplify the assembly steps of the guide member 142 while ensuring the sealing performance of the guide member 142.

[0105] In any of the above embodiments, the mounting portion 140 further includes an opening. The opening is provided at one end of the base body 141. The opening communicates with the atomization chamber 143. The opening is used to allow the aerosol-generating substrate to enter the atomization chamber 143.

[0106] In this embodiment, the mounting portion 140 further includes an opening provided at one end of the base body 141. The opening faces the outside of the housing 110. The opening communicates with the atomization chamber 143 and is used to load the aerosol-generating substrate into the atomization chamber 143 through the opening.

[0107] As can be seen, the aerosol-generating substrate is provided with an inhalation portion that protrudes from the atomization chamber 143 through an opening, allowing a user to inhale the aerosol-generating substrate through the inhalation portion.

[0108] As shown in FIG. 3, in any of the above embodiments, the aerosol generating device 100 further includes a first through-hole 160 .

[0109] The first through-hole 160 is provided in the housing 110, and the resonant cavity 120 communicates with the outside of the room through the first through-hole 160.

[0110] The mounting portion 140 further includes a second through-hole 144 provided in the base body 141. The atomization chamber 143 communicates with the resonant cavity 120 through the second through-hole 144.

[0111] In this embodiment, the aerosol generating device 100 includes a first through hole 160 and a second through hole 144. The first through hole 160 is provided in the housing 110 and connects the resonant cavity 120 to the outside of the housing 110. The second through hole 144 is provided in the base body 141 and connects the resonant cavity 120 to the atomization chamber 143. When a user inhales through the inhalation portion of the aerosol-generating substrate, gas outside the housing 110 passes through the first through hole 160, the resonant cavity 120, the second through hole 144, the atomization chamber 143, and the aerosol-generating substrate in that order. When the aerosol-generating substrate is heated, precipitates mix with the gas to form an aerosol, which is then discharged from the inhalation portion. This gas flow path allows air outside the housing 110 to be constantly replenished into the atomization chamber 143 during the inhalation process of the aerosol-generating substrate, ensuring sufficient atomization of the aerosol-generating substrate. It also prevents the aerosol-generating substrate from having an excessively large resistance to drawing due to an excessively small airflow, thereby improving the user experience.

[0112] As shown in FIGS. 4 and 5, in either of the above embodiments, the mounting portion 140 further includes at least two protrusions 145 .

[0113] At least two protrusions 145 are provided on the inner wall of the atomization chamber 143. Furthermore, the at least two protrusions 145 protrude from the inner wall of the atomization chamber 143. A gap is provided between two adjacent protrusions 145 of the at least two protrusions 145. The at least two protrusions 145 are used to fix the aerosol-generating substrate.

[0114] In this embodiment, the mounting portion 140 further includes at least two protrusions 145 provided on the inner wall of the atomization chamber 143. The at least two protrusions 145 can secure the aerosol-generating substrate. When the aerosol-generating substrate is inserted into the atomization chamber 143 through the opening, the at least two protrusions 145 abut against the outer wall of the aerosol-generating substrate, thereby securing the aerosol-generating substrate. This prevents the aerosol-generating substrate from slipping out of the atomization chamber 143.

[0115] Adjacent two of the at least two protrusions 145 are spaced apart from one another. An airflow path is formed by the gap between the adjacent two protrusions 145 and the gap between the aerosol-generating substrate and the side wall of the atomization chamber 143.

[0116] When a user inhales the aerosol-generating substrate through the inhalation portion, gas outside the housing 110 passes through the gap between two adjacent protrusions 145, the gap between the aerosol-generating substrate and the side wall of the atomization chamber 143, and then through the aerosol-generating substrate. When the aerosol-generating substrate is heated, precipitates mix with the gas to form an aerosol, which is then discharged through the inhalation portion. This allows air outside the housing 110 to be constantly replenished into the atomization chamber 143 during the inhalation process of the aerosol-generating substrate, ensuring sufficient atomization of the aerosol-generating substrate. This also prevents excessively high resistance to inhalation of the aerosol-generating substrate due to an excessively small airflow, improving the user experience.

[0117] In any of the above embodiments, the at least two protrusions 145 are located on the inner wall of the atomization chamber 143 adjacent to the opening. The at least two protrusions 145 are also uniformly distributed around the circumference of the atomization chamber 143.

[0118] In this embodiment, at least two protrusions 145 are provided on the atomization chamber 143. ZhouThe protrusions 145 are uniformly arranged along the direction of the nozzle opening. The uniformly distributed protrusions 145 can effectively fix the aerosol-generating substrate, preventing the aerosol-generating substrate from falling out of the atomization chamber 143 during inhalation. Furthermore, although the aerosol-generating substrate generates some dust during inhalation, at least two protrusions 145 are provided at one end close to the opening, allowing the user to easily clean the dust adhering to the protrusions 145. This prevents dust from clogging the gaps between the protrusions 145, improving the operational stability of the aerosol generating device 100.

[0119] As shown in FIGS. 6 and 7, in any of the above embodiments, the mounting portion 140 further includes a recess 146 .

[0120] The groove 146 is provided on the inner wall of the atomization chamber 143. The groove 146 extends along the center line of the atomization chamber 143.

[0121] In this embodiment, the mounting part 140 further includes a groove 146 formed in the inner wall of the atomization chamber 143. After the aerosol-generating substrate is inserted into the atomization chamber 143 through the opening, the aerosol-generating substrate comes into contact with the inner wall of the atomization chamber 143, and the friction between the inner wall of the atomization chamber 143 and the aerosol-generating substrate prevents the aerosol-generating substrate from falling out of the atomization chamber 143.

[0122] When a user inhales through the inhalation port of the aerosol-generating substrate, gas outside the housing 110 passes through the groove 146 and the aerosol-generating substrate in that order. When the aerosol-generating substrate is heated, precipitates mix with the gas to form an aerosol, which is then expelled from the inhalation port. This allows air outside the housing 110 to be constantly replenished into the atomization chamber 143 during the inhalation process of the aerosol-generating substrate, ensuring sufficient atomization of the aerosol-generating substrate. This also prevents excessive resistance to inhalation of the aerosol-generating substrate due to an excessively small airflow, improving the user experience.

[0123] In any of the above embodiments, the number of the grooves 146 is at least two. In addition, the at least two grooves 146 are uniformly distributed along the circumferential direction of the atomization chamber 143.

[0124] In this embodiment, the plurality of grooves 146 are uniformly distributed on the inner circumferential sidewall of the atomization chamber 143, allowing the external air to uniformly contact the aerosol-generating substrate. This allows the precipitate of the aerosol-generating substrate to be sufficiently mixed with the air to form an aerosol, thereby improving the atomization efficiency of the aerosol-generating substrate.

[0125] As can be seen, the resistance to drawing of the aerosol generating device 100 can be adjusted by rationally setting the number and inner diameter of the grooves 146.

[0126] As shown in FIGS. 8 and 9, in either of the above embodiments, the mounting portion 140 further includes a spacer 147.

[0127] A spacer 147 is provided in the atomization chamber 143. The spacer 147 divides the atomization chamber 143 into a first chamber 1432 and a second chamber 1434. The first chamber 1432 communicates with the second chamber 1434. The first chamber 1432 is used to accommodate an aerosol-generating substrate.

[0128] In this embodiment, the mounting portion 140 further includes a spacer 147 provided within the atomization chamber 143. The spacer 147 divides the atomization chamber 143 into a first chamber 1432 and a second chamber 1434 that communicate with each other. The first chamber 1432 is used to contain the aerosol-generating substrate, and the second chamber 1434 communicates with the air outside the atomization chamber 143.

[0129] When a user inhales through the inhalation portion of the aerosol-generating substrate, air outside the housing 110 passes through the second chamber 1434, the first chamber 1432, and the aerosol-generating substrate in that order. That is, the air passes through the second chamber 1434, enters the first chamber 1432, and comes into contact with the aerosol-generating substrate. When the aerosol-generating substrate is heated, precipitates mix with the gas to form an aerosol, which is then discharged through the inhalation portion. This allows air outside the housing 110 to be constantly replenished into the atomization chamber 143 during the inhalation process of the aerosol-generating substrate, ensuring sufficient atomization of the aerosol-generating substrate. Furthermore, this configuration also prevents excessively high resistance to inhalation of the aerosol-generating substrate due to an excessively small airflow, improving the user experience.

[0130] In either embodiment, the first chamber 1432 and the second chamber 1434 are coaxially distributed in an annular shape, and the second chamber 1434 is located outside the first chamber 1432.

[0131] In this embodiment, the second chamber 1434 is provided in a ring shape outside the first chamber 1432, so that the air passes through the second chamber 1434 and then uniformly enters the first chamber 1432 from the outside. This allows the external air to come into uniform contact with the aerosol-generating substrate, allowing the deposits of the aerosol-generating substrate to mix sufficiently with the air and form an aerosol. This improves the atomization effect of the aerosol-generating substrate.

[0132] In any of the above embodiments, the mounting portion 140 further includes a third through hole.

[0133] The third through-hole is provided in the spacer 147. The third through-hole is located at one end of the spacer 147 that is connected to the bottom wall of the atomization chamber 143.

[0134] In this embodiment, the mounting portion 140 further includes a third through-hole, which is provided in the spacer 147 and allows the first chamber 1432 and the second chamber 1434 to communicate with each other.

[0135] In any of the above embodiments, the mounting portion 140 further includes a support portion.

[0136] The support portion is provided on the bottom wall of the atomization chamber 143. The support portion protrudes from the bottom wall of the atomization chamber 143.

[0137] In this embodiment, the mounting part 140 further includes a support part provided on the bottom wall of the atomization chamber 143. The support part supports the aerosol-generating substrate, thereby creating a gap between the aerosol-generating substrate and the bottom wall of the atomization chamber 143. This allows air entering the atomization chamber 143 from the outside to come into contact with the bottom end of the aerosol-generating substrate, further improving the mixing effect between the air and the precipitate formed when the aerosol-generating substrate is heated. This allows the precipitate on the aerosol-generating substrate to be sufficiently mixed with the air to form an aerosol, thereby improving the atomization effect of the aerosol-generating substrate.

[0138] In either embodiment, the housing 110 includes a body 112 and an end cover 114 .

[0139] The end cover 114 is removably connected to the body 112. The mounting portion 140 is inserted into the end cover 114. The end cover 114 and the body 112 surround the resonant cavity 120.

[0140] In this embodiment, the housing 110 includes a main body 112 and an end cover 114. The mounting portion 140 is provided on the end cover 114, and the end cover 114 is removably connected to the main body 112. This makes it convenient for a user to remove the end cover 114 and disassemble and clean the mounting portion 140 separately, thereby avoiding damage caused by water getting in when cleaning the entire aerosol generation device 100.

[0141] In any of the above embodiments, the aerosol generating device 100 further comprises a resonating rod 170 .

[0142] The resonant rod 170 is provided in the resonant cavity 120. A first end of the resonant rod 170 is connected to the bottom wall of the resonant cavity 120, and a second end of the resonant rod 170 is connected to the mounting portion 140. handle It will be established as follows.

[0143] In this embodiment, the resonant rod 170 is used for resonant transmission of microwaves. A first end of the resonant rod 170 is connected to the bottom wall of the resonant cavity 120, and a second end of the resonant rod 170 is connected to the mounting portion 140. handle The microwaves supplied by the microwave module 130 into the resonant cavity 120 are transmitted from the first end to the second end of the resonant rod 170, thereby microwave-heating the aerosol-generating substrate in the atomization chamber 143 of the mounting part 140.

[0144] Since the atomization chamber 143 and the resonant cavity 120 are isolated by the mounting portion 140, it is possible to prevent liquid or solid debris generated after atomization of the aerosol-generating substrate in the atomization chamber 143 from entering the resonant cavity 120. This prevents the microwave module 130 from failing due to debris entering the resonant cavity 120.

[0145] In some embodiments, the inner walls of the resonant cavity 120 and the resonant rod 170 are made of a conductive material. Conductive materials are For example, metal materials such as gold, copper, and silver but It is selectable.

[0146] In some embodiments, the inner wall of the resonant cavity 120 and the outer wall of the resonant rod 170 are provided with a conductive coating layer, such as a metal coating layer, such as a gold-plated layer, a copper-plated layer, or a silver-plated layer. is selectable.

[0147] In these embodiments, a metal with high stability and excellent conductivity is selected to form the resonant cavity 120 and the resonant rod 170. This not only prevents microwaves from leaking out, but also prevents the inner wall of the resonant cavity 120 and the resonant rod 170 from rusting.

[0148] In some embodiments, the portion of the mounting portion 140 located inside the resonant cavity 120 is made of a material with low dielectric loss, such as a PTFE (polytetrafluoroethylene) material, a glass material, or a ceramic material, which allows microwaves to be transmitted to the atomization chamber 143 inside the mounting portion 140, thereby heating the aerosol-generating substrate in the atomization chamber 143 and generating an aerosol.

[0149] In some embodiments, the mounting portion 140 is removably connected to the housing 110 .

[0150] In these embodiments, atomization chamber 143 for containing the aerosol-generating substrate is provided within mounting portion 140. Thus, by removing mounting portion 140, atomization chamber 143 can be disassembled and cleaned independently, improving the user experience.

[0151] As shown in FIGS. 1 and 2, in either of the above embodiments, the resonating rod 170 is spaced apart from the mounting portion 140 .

[0152] In this embodiment, by providing a gap between the resonating rod 170 and the mounting portion 140, it is possible to prevent the resonating rod 170 from being pressed during the process of assembling the mounting portion 140 to the housing 110. This reduces the requirements for precision in production and assembly of the resonating rod 170 and the mounting portion 140.

[0153] 1, in any of the above embodiments, the aerosol generating device 100 further includes a fixing part 180 provided on the mounting part 140 and positioned within the resonant cavity 120. The fixing part 180 includes a position restricting chamber, and at least a portion of the resonant rod 170 is positioned within the position restricting chamber.

[0154] In this embodiment, the aerosol generating device 100 further includes a fixing part 180 provided on the mounting part 140. A position restriction chamber is provided within the fixing part 180, and at least a portion of the resonating rod 170 is positioned within the position restriction chamber. The fixing part 180 fixes the resonating rod 170 via the position restriction chamber, thereby providing a certain degree of vibration damping effect for the resonating rod 170. This prevents the resonating rod 170 from falling off due to vibration.

[0155] In some embodiments, the fixed portion 180 and the mounting portion 140 are integrally molded.

[0156] In these embodiments, the fixed portion 180 and the mounting portion 140 are integrally formed and have a high bonding strength, so that the stabilization effect of the fixed portion 180 on the resonating rod 170 is improved.

[0157] As shown in FIGS. 1 and 2, in any of the above embodiments, the axis of the atomization chamber 143 and the axis of the resonating rod 170 are coaxial.

[0158] In this embodiment, the atomization chamber 143 and the resonator rod 170 are arranged coaxially, which ensures that the microwaves transmitted to the atomization chamber 143 via the resonator rod 170 are transmitted to the center of the atomization chamber 143. This improves the uniformity when the microwaves heat the aerosol-generating substrate in the atomization chamber 143, and prevents uneven heating of the aerosol-generating substrate caused by the concentration of microwaves in the atomization chamber 143, thereby further improving the atomization effect of the aerosol-generating substrate.

[0159] As shown in FIGS. 1 and 2, in either of the above embodiments, microwave module 130 includes microwave introduction section 132.

[0160] The microwave introduction part 132 is provided on a side wall of the housing 110. The microwave introduction part 132 is in communication with the resonant cavity 120. In addition, a microwave emission source 134 is connected to the microwave introduction part 132. Microwaves output from the microwave emission source 134 are supplied to the resonant cavity 120 via the microwave introduction part 132. As a result, the microwaves are transmitted in a direction from the first end of the resonant rod 170 to the second end of the resonant rod 170.

[0161] In this embodiment, the microwave module 130 includes a microwave emission source 134 and a microwave introduction section 132. The microwave emission source 134 is used to generate microwaves. The microwave introduction section 132, which is provided on the side wall of the housing 110, is used to transport the microwaves generated by the microwave emission source 134 into the resonant cavity 120. The microwaves are supplied to the resonant cavity 120 via the microwave introduction section 132. The microwaves can then be transmitted in a direction from the first end of the resonant rod 170 to the second end of the resonant rod 170. This allows the microwaves to directly act on the aerosol-generating substrate in the atomization chamber 143, thereby improving the atomization effect of the aerosol-generating substrate.

[0162] As shown in FIG. 1, in any of the above embodiments, the microwave introduction section 132 includes a first introduction member 1322 and a second introduction member 1324.

[0163] The first introduction member 1322 is provided on the side wall of the housing 110. The first introduction member 1322 is connected to a microwave emission source .

[0164] A first end of the second introduction member 1324 is connected to the first introduction member 1322. The second introduction member 1324 is located within the resonant cavity 120. A second end of the second introduction member 1324 faces the bottom wall of the resonant cavity 120.

[0165] In this embodiment, the microwave introduction section 132 includes a first introduction member 1322 and a second introduction member 1324. The first introduction member 1322 is inserted into the side wall of the housing 110. A first end of the first introduction member 1322 is connected to the microwave emission source 134. Thus, microwaves generated by the microwave emission source 134 enter the microwave introduction section 132 from the first end of the first introduction member 1322. A second end of the first introduction member 1322 is connected to a first end of the second introduction member 1324. A second end of the second introduction member 1324 faces the bottom wall of the resonant cavity 120. The microwaves are transmitted via the first introduction member 1322 and the second introduction member 1324, and then transmitted from the bottom wall of the resonant cavity 120 to the atomization chamber 143, where they atomize the aerosol-generating substrate in the atomization chamber 143 by microwave heating.

[0166] The first introduction portion is provided coaxially with the microwave output end of the microwave emission source 134. The second introduction member has a horizontal introduction portion and a vertical introduction portion. The axis of the horizontal introduction portion is parallel to the bottom wall of the resonant cavity 120, and the axis of the vertical introduction portion is perpendicular to the bottom wall of the resonant cavity 120. The horizontal introduction portion is connected to the vertical introduction portion via a bent portion. The horizontal introduction portion is also provided coaxially with the first introduction portion. By providing the microwave introduction portion 132 as described above, all of the microwaves generated by the microwave emission source 134 can enter the resonant cavity 120 and be transmitted within the resonant cavity 120 by the resonant rod 170.

[0167] As shown in FIG. 2, in any of the above embodiments, the aerosol generating device 100 further includes a recess 190 .

[0168] A recess 190 is provided in the bottom wall of the resonant cavity 120 , and the second end of the second lead-in member is located within the recess 190 .

The recess 190 is connected to the second end of the second lead-in member. In responseThe second end of the second introduction member extends into the recess 190. This allows the microwaves that have entered the resonant cavity 120 to be transmitted in a direction from the second end to the first end of the resonant rod 170, thereby reducing energy loss during the microwave transmission process.

[0170] As shown in FIG. 10, in any of the above embodiments, the microwave introduction section 132 includes a third introduction member 1326 .
