Description

Technical Field

[0001] The present application belongs to the field of electronic atomization technology, and specifically relates to an aerosol generating device. Background Art

[0002] A Heat Not Burning (HNB) device is an electronic device that heats an aerosol-generating substrate (processed plant leaf products) without causing combustion. This device heats the substrate to a temperature high enough to generate aerosol but not high enough to burn. This allows the substrate to produce the desired aerosol without burning.

[0003] Currently, HNB devices on the market primarily utilize resistive heating, using a central heating element or needle inserted from the center of the aerosol-generating matrix into the interior of the aerosol-generating matrix for heating. This type of device requires a long preheating wait time before use, cannot be freely withdrawn and stopped, and unevenly carbonizes the aerosol-generating matrix, resulting in insufficient baking of the aerosol-generating matrix and low utilization. Furthermore, the heating element of the HNB device easily accumulates dirt in the aerosol-generating matrix extractor and the heating element base, making it difficult to clean. This can cause the local aerosol-generating matrix in contact with the heating element to overheat, partially cracking, and releasing substances harmful to the human body. Therefore, microwave heating technology has gradually replaced resistive heating as the new heating method. Microwave heating technology is characterized by high efficiency, timelyness, selectivity, and no delay in heating, and it only heats substances with specific dielectric properties. The advantages of using microwave heating for atomization are: a. Microwave heating is radiation heating, not heat conduction, which allows for instant smoking and stopping; b. There is no heating plate, so there is no problem of plate breakage or cleaning of the heating plate; c. The aerosol generation matrix utilization rate is high, the taste consistency is high, and the taste is closer to that of cigarettes.

[0004] However, existing microwave-heated HNB devices cannot promptly stop the microwave components from operating after the user stops inhaling, resulting in a waste of electrical energy and aerosol matrix. Summary of the Invention

[0005] This application aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] To this end, the present application proposes an aerosol generating device.

[0007] In view of this, according to the present application, an aerosol generating device is proposed, comprising: a shell, the shell including a resonant cavity; a microwave component, arranged in the shell, the microwave component being used to feed microwaves into the resonant cavity; a mounting portion, arranged in the shell, at least a portion of the mounting portion being located in the resonant cavity, the mounting portion including an atomization cavity, the atomization cavity being used to accommodate an aerosol generating matrix; a pressure sensor, arranged in the shell, located outside the resonant cavity, the collection end of the pressure sensor being connected to the atomization cavity, and being used to collect the air pressure value in the atomization cavity.

[0008] The present application provides an aerosol generating device comprising a housing, a microwave assembly, a mounting portion, and a pressure sensor. A resonant cavity is disposed within the housing, a microwave output terminal of the microwave assembly is connected to the resonant cavity, and microwaves generated by the microwave assembly are fed into the resonant cavity. The mounting portion is disposed within the housing, and an atomizing cavity is disposed within the mounting portion. The atomizing cavity is used to accommodate an aerosol generating substrate. The microwave assembly feeds into the resonant cavity, where it is conducted through the resonant cavity to the mounting portion, thereby heating the aerosol generating substrate within the atomizing cavity.

[0009] The mounting portion isolates the resonant cavity and the atomization cavity from each other, thereby preventing liquid waste or solid waste generated after the aerosol generating matrix in the atomization cavity is atomized from entering the resonant cavity, thereby avoiding the occurrence of malfunction of the aerosol generating device due to waste entering the resonant cavity.

[0010] The aerosol generating device also includes a pressure sensor, whose collection end is connected to the atomizing chamber. The pressure sensor is capable of collecting air pressure within the atomizing chamber. The pressure sensor is disposed within the housing and positioned outside the resonant cavity, so that it is not affected by microwaves transmitted through the resonant cavity. The pressure sensor collects changes in air pressure within the atomizing chamber, and based on these changes, it is possible to detect whether the aerosol generating device is in a puffing state. The operation of the microwave assembly is controlled based on the puffing state of the aerosol generating device.

[0011] In some embodiments, when the aerosol-generating device is detected to be in the puffing state, the microwave assembly is controlled to operate, thereby performing microwave heating and atomization on the aerosol-generating substrate in the atomization chamber. When the aerosol-generating device is not in the puffing state, the microwave assembly is controlled to stop operating and does not continue to heat and atomize the aerosol-generating substrate in the atomization chamber.

[0012] In some other embodiments, the aerosol generating device is in the on state and receives a preheating control instruction, and controls the microwave component to operate at the first power until the cavity temperature value of the atomizing chamber enters the set temperature value range, so that the cavity temperature value is maintained within the set temperature value range, which can play a role in preheating the aerosol generating matrix in the atomizing chamber. Detect whether the aerosol generating device is in the suction state, and adjust the first power according to the suction state of the aerosol generating device. Specifically, if it is detected that the aerosol generating device is in the suction state, the microwave component is controlled to operate at the second power, thereby quickly increasing the temperature in the atomizing chamber, so that the aerosol generating matrix is ​​quickly heated and atomized to produce an aerosol, wherein the second power is greater than the first power. If it is detected that the aerosol generating device is not in the suction state, the microwave component is controlled to maintain the first power operation and continue to preheat the aerosol generating matrix.

[0013] The present application uses a pressure sensor to collect the air pressure value in the atomization chamber, thereby detecting whether the aerosol generating device is in the suction state, and controlling the operation of the microwave component according to the suction state. After the user stops suctioning, the microwave component can be promptly controlled to stop operating, thereby avoiding the waste of electrical energy and aerosol generating substrate. The aerosol generating substrate is preheated when the aerosol generating device is in the non-suction state, and the aerosol generating substrate can be quickly heated to the atomization temperature in the suction state, thereby reducing energy consumption while improving the atomization efficiency of the aerosol generating substrate and improving the atomization process of the aerosol generating substrate, thereby improving the user experience.

[0014] In addition, the aerosol generating device according to the above technical solution provided by this application may also have the following additional technical features:

[0015] In a possible design, the mounting portion includes: a base body, the atomization chamber is arranged on the base body; a conductive member, one end of the conductive member is connected to the base body, and the other end of the conductive member is connected to the collection end of the pressure sensor.

[0016] In this design, the mounting portion includes a base and a conductive member. The base is disposed within the housing, and the base and the atomization chamber enclose a resonant cavity. The conductive member is disposed through the housing, one end of the conductive member being connected to the base and communicating with the atomization chamber, while the other end of the conductive member extends to the outside of the housing and is connected to a pressure sensor. The conductive member connects the atomization chamber to the pressure sensor outside the housing, allowing the pressure sensor to directly collect the intracavity pressure value of the atomization chamber.

[0017] In one possible design, the conductive part includes: a first tube part, which is integrally formed on the base body; a second tube part, which is arranged in the shell, the first end of the second tube part passes through the shell and is connected to the first tube part, the second end of the second tube part is connected to the pressure sensor, and the collection end of the pressure sensor is located in the second tube part.

[0018] In this design, the conductive member comprises a first tube and a second tube. The first tube is connected to the base. The second tube is mounted on the side wall of the housing and extends through the housing to connect to the first tube. The second tube's end, located outside the housing, is connected to the pressure sensor. Connecting the conductive member to the first and second tubes simplifies the assembly process of the aerosol generating device and facilitates separate disassembly and cleaning of the mounting portion.

[0019] The first pipe is integrally formed with the base, further reducing the number of assembly steps. The second pipe is mounted on the housing via a fixing member, which can be a screw, rivet or other fastener.

[0020] The steps of assembling the conductive member and the mounting portion include: inserting the base body integrally formed with the first tube into the interior of the housing. Inserting the second tube into the side wall of the housing, the second tube is plugged into the first tube so that the first and second tubes are connected to the atomizing chamber in the base body, and the sealing performance of the connection between the first and second tubes is ensured. The second tube is fixed to the side wall of the housing by fasteners, thereby completing the assembly process of the conductive member and the mounting portion. By respectively arranging the first and second tubes inside and outside the housing, and then connecting the first and second tubes to each other, the assembly steps of the conductive member can be simplified while ensuring the sealing performance of the conductive member.

[0021] In a possible design, the mounting portion further includes: an opening, which is provided at one end of the base body, the opening being in communication with the atomization chamber, and the opening being used to allow the aerosol-generating matrix to enter the atomization chamber.

[0022] In this design, the mounting portion further includes an opening disposed at one end of the base body, the opening facing the exterior of the housing, and the opening communicating with the atomization chamber for inserting the aerosol-generating substrate into the atomization chamber through the opening.

[0023] It can be understood that the aerosol generating substrate is provided with a suction portion, which protrudes from the atomization cavity through the opening, and the user can inhale the aerosol generating substrate through the suction portion.

[0024] In one possible design, the aerosol generating device further includes: a first through hole, arranged in the shell, and the resonant cavity is connected to the outside of the cavity through the first through hole; the mounting portion further includes: a second through hole, arranged in the base body, and the atomization cavity is connected to the resonant cavity through the second through hole.

[0025] In this design, the aerosol generating device includes a first through hole and a second through hole. The first through hole is provided in the shell so that the resonant cavity is connected to the outside of the shell, and the second through hole is provided in the base so that the resonant cavity is connected to the atomization cavity. When the user inhales through the suction part of the aerosol generating matrix, the gas outside the shell flows through the first through hole, the resonant cavity, the second through hole, the atomization cavity, and the aerosol generating matrix in sequence. The heated precipitate of the aerosol generating matrix mixes with the gas to form an aerosol, and the formed aerosol is discharged from the suction part, thereby forming a gas flow channel. This ensures that during the suction process of the aerosol generating matrix, the air outside the shell can be continuously replenished into the atomization cavity, so that the aerosol generating matrix can be fully atomized. It can also avoid the aerosol generating matrix having too large a suction resistance due to too small an airflow, thereby improving the user experience.

[0026] In one possible design, the mounting portion further includes: at least two protrusions, arranged on the inner side wall of the atomization chamber, at least two protrusions protruding from the inner side wall of the atomization chamber, a gap being provided between two adjacent protrusions of at least two protrusions, and at least two protrusions being used to fix the aerosol generating matrix.

[0027] In this design, the mounting portion also includes at least two protrusions disposed on the inner sidewall of the atomization chamber. These at least two protrusions secure 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 sidewall of the aerosol-generating substrate to secure it and prevent it from slipping out of the atomization chamber.

[0028] Two adjacent protrusions of the at least two protrusions are spaced apart, and the gap between the two adjacent protrusions and the space between the aerosol generating substrate and the side wall of the atomizing chamber form an air flow channel.

[0029] When a user draws in air through the suction portion of the aerosol-generating matrix, gas outside the housing flows sequentially through the gap between two adjacent protrusions, the gap between the aerosol-generating matrix and the sidewall of the atomization chamber, and the aerosol-generating matrix. The heated precipitate from the aerosol-generating matrix mixes with the gas to form an aerosol, which is then discharged from the suction portion. This ensures that during the inhalation process of the aerosol-generating matrix, air outside the housing can continuously be replenished and enter the atomization chamber, allowing the aerosol-generating matrix to be fully atomized. This also prevents excessive inhalation resistance of the aerosol-generating matrix due to insufficient airflow, thereby improving the user experience.

[0030] In a possible design, at least two protrusions are located on the inner side wall of the atomization chamber close to the opening, and the at least two protrusions are evenly distributed along the circumference of the atomization chamber.

[0031] In this design, at least two protrusions are evenly spaced along the axial direction of the atomizing chamber. These evenly distributed protrusions effectively secure the aerosol-generating substrate, preventing it from falling out of the aerosol-generating chamber during inhalation. The inhalation of the aerosol-generating substrate generates some waste, and the at least two protrusions positioned near one end of the opening facilitate cleaning of any waste adhering to the protrusions, preventing it from clogging the gaps between the protrusions and improving the operational stability of the aerosol-generating device.

[0032] In a possible design, the mounting portion further includes: a groove, which is arranged on the inner side wall of the atomization chamber and extends along the center line direction of the atomization chamber.

[0033] In this design, the mounting portion further includes a groove formed on the inner sidewall of the atomization chamber. After the aerosol-generating substrate is inserted into the atomization chamber through the opening, the substrate contacts the inner sidewall of the atomization chamber. The friction between the inner sidewall of the atomization chamber and the substrate prevents the substrate from falling out of the atomization chamber.

[0034] When a user draws in air through the suction portion of the aerosol-generating matrix, gas outside the housing flows sequentially through the groove and the aerosol-generating matrix. The heated precipitates from the aerosol-generating matrix mix with the gas to form an aerosol, which is then discharged from the suction portion. This ensures that during the inhalation process, air outside the housing can continuously be replenished into the atomization chamber, allowing the aerosol-generating matrix to be fully atomized. This also prevents excessive inhalation resistance of the aerosol-generating matrix due to insufficient airflow, thereby improving the user experience.

[0035] In a possible design, the number of the grooves is at least two, and the at least two grooves are evenly distributed along the circumference of the atomization chamber.

[0036] In this design, multiple grooves are evenly distributed on the inner side wall of the atomization chamber, so that the external air can evenly contact the aerosol generating matrix, and the precipitate of the aerosol generating matrix can be fully mixed with the air to form an aerosol, thereby improving the atomization effect of the aerosol generating matrix.

[0037] It is understandable that a reasonable setting of the number and inner diameter of the grooves can help adjust the draw resistance of the aerosol generating device.

[0038] In one possible design, the mounting portion further includes: an isolator, disposed in the atomization chamber, the isolator dividing the atomization chamber into a first cavity and a second cavity, the first cavity being connected to the second cavity, and the first cavity being used to accommodate the aerosol generating matrix.

[0039] In this design, the mounting portion also includes an isolating member arranged in the atomizing chamber, which separates the atomizing chamber into a first cavity and a second cavity that are interconnected. The first cavity is used to accommodate the aerosol generating matrix, and the second cavity is connected to the air outside the atomizing chamber.

[0040] When a user draws in air through the suction portion of the aerosol-generating matrix, air outside the housing flows sequentially through the second cavity, the first cavity, and the aerosol-generating matrix. That is, the air passes through the second cavity and enters the first cavity, where it comes into contact with the aerosol-generating matrix. The heated precipitates from the aerosol-generating matrix mix with the gas to form an aerosol, which is then discharged from the suction portion. This ensures that during the inhalation process of the aerosol-generating matrix, air outside the housing can continuously be replenished and enter the atomization chamber, allowing the aerosol-generating matrix to be fully atomized. This also prevents excessive inhalation resistance of the aerosol-generating matrix due to insufficient airflow, thereby improving the user experience.

[0041] In a possible design, the first cavity and the second cavity are coaxially distributed in an annular shape, and the second cavity is located outside the first cavity.

[0042] In this design, the second cavity is annularly arranged outside the first cavity, so that the air flows through the second cavity and then enters the first cavity evenly from the outside, thereby achieving uniform contact between the external air and the aerosol generating matrix, so that the precipitate of the aerosol generating matrix can be fully mixed with the air to form an aerosol, thereby improving the atomization effect of the aerosol generating matrix.

[0043] In a possible design, the mounting portion further includes: a third through hole, which is provided in the isolation member, and the third through hole is located at an end of the isolation member connected to the bottom wall of the atomization chamber.

[0044] In this design, the mounting portion further includes a third through hole, which is provided in the isolating member and connects the first cavity with the second cavity.

[0045] In a possible design, the mounting portion further includes: a supporting portion, which is arranged on the bottom wall of the atomization chamber, and the supporting portion protrudes from the bottom wall of the atomization chamber.

[0046] In this design, the mounting portion also includes a support portion disposed on the bottom wall of the atomization chamber. The support portion is used to support the aerosol-generating substrate, creating a gap between the aerosol-generating substrate and the bottom wall of the atomization chamber. This allows air entering the atomization chamber to contact the bottom end of the aerosol-generating substrate, further enhancing the mixing effect between the air and the heated precipitates of the aerosol-generating substrate, allowing the precipitates of the aerosol-generating substrate to fully mix with the air to form an aerosol, thereby improving the atomization effect of the aerosol-generating substrate.

[0047] In a possible design, the shell includes: a main body; an end cover detachably connected to the main body, the mounting portion passes through the end cover, and the end cover and the main body enclose a resonant cavity.

[0048] In this design, the housing includes a main body and an end cap. The mounting portion is located on the end cap, which is detachably connected to the main body. This allows the user to remove the end cap to clean the mounting portion separately, preventing water ingress during cleaning of the entire aerosol generating device.

[0049] In one possible design, the aerosol generating device further includes: a resonant column disposed in the resonant cavity, wherein a first end of the resonant column is connected to a bottom wall of the cavity wall of the resonant cavity, and a second end of the resonant column is disposed opposite to the mounting portion.

[0050] In this design, a resonant column is used to resonate and conduct microwaves. The first end of the resonant column is connected to the bottom wall of the resonant cavity, and the second end of the resonant column is located opposite the mounting portion. Microwaves fed into the resonant cavity by the microwave assembly are transmitted along the resonant column's first end to the second end, thereby heating the aerosol-generating substrate within the atomization cavity of the mounting portion.

[0051] The atomizing cavity and the resonant cavity are isolated from each other by the mounting portion, which can prevent liquid waste or fixed waste generated after the aerosol generating matrix in the atomizing cavity is atomized from entering the resonant cavity, thereby avoiding the occurrence of microwave component failure caused by waste entering the resonant cavity.

[0052] In some embodiments, the inner wall of the resonant cavity and the resonant column are made of a conductive material, which may be a metal material, such as gold, copper, or silver.

[0053] In some embodiments, the inner wall of the resonant cavity and the outer wall of the resonant column are provided with a conductive coating, and the conductive coating is selected as a metal coating, such as a gold-plated layer, a copper-plated layer, or a silver-plated layer.

[0054] In these embodiments, metals with high stability and good conductivity are selected to set up the resonant cavity and the resonant column, which not only prevents microwave leakage, but also prevents the inner wall of the resonant cavity and the resonant column from rusting.

[0055] In some embodiments, the portion of the mounting portion located within the resonant cavity is made of a low dielectric loss material, such as PTFE (polytetrafluoroethylene), glass, or ceramic, to enable microwaves to be conducted into the atomizing cavity within the mounting portion, thereby heating the aerosol-generating substrate in the atomizing cavity and generating aerosol.

[0056] In some embodiments, the mounting portion is detachably connected to the housing.

[0057] In these embodiments, the atomization chamber for accommodating the aerosol-generating substrate is disposed in the mounting portion. The atomization chamber can be separately disassembled and cleaned by disassembling the mounting portion, thereby improving the user experience.

[0058] In a possible design, the resonant column and the mounting portion are spaced apart.

[0059] In this design, by providing a gap between the resonant column and the mounting portion, it is possible to avoid squeezing the resonant column during the assembly of the mounting portion into the housing, thereby reducing the production and assembly accuracy requirements for the resonant column and the mounting portion.

[0060] In a possible design, the aerosol generating device further includes: a fixing portion, which is arranged on the mounting portion and is located in the resonant cavity, the fixing portion includes a limiting cavity, and at least a portion of the resonant column is located in the limiting cavity.

[0061] In this design, the aerosol generating device also includes a fixing portion arranged on the mounting portion, a limiting cavity is arranged in the fixing portion, at least a portion of the resonant column is located in the limiting cavity, and the fixing portion fixes the resonant column through the limiting cavity, thereby playing a certain anti-vibration role on the resonant column and preventing the resonant column from falling off due to vibration.

[0062] In some embodiments, the fixing portion and the mounting portion are integrally formed.

[0063] In these embodiments, the fixing portion and the mounting portion are integrally formed together, thereby having a higher bonding strength, thereby improving the stabilizing effect of the fixing portion on the resonant column.

[0064] In a possible design, the axis of the atomization chamber is coaxial with the axis of the resonant column.

[0065] In this design, the atomization chamber and the resonance column are coaxially arranged, which can ensure that the microwaves transmitted to the atomization chamber through the resonance column can be transmitted to the middle position of the atomization chamber, thereby improving the uniformity of microwave heating of the aerosol generating matrix in the atomization chamber, avoiding uneven heating of the aerosol generating matrix caused by the concentration of microwaves in the atomization chamber, and further improving the atomization effect of the aerosol generating matrix.

[0066] In one possible design, the microwave component includes: a microwave introduction portion, which is arranged on the side wall of the shell and is connected to the resonant cavity; a microwave emission source, which is connected to the microwave introduction portion, and the microwaves output by the microwave emission source are fed into the resonant cavity through the microwave introduction portion, so that the microwaves are transmitted along the direction from the first end of the resonant column to the second end of the resonant column.

[0067] In this design, the microwave assembly includes a microwave emission source and a microwave inlet. The microwave emission source generates microwaves, while the microwave inlet, located on the side wall of the housing, transmits the microwaves generated by the microwave emission source into the resonant cavity. After being fed into the resonant cavity through the microwave inlet, the microwaves are transmitted along the first end of the resonant column to the second end of the resonant column, allowing the microwaves to directly act on the aerosol-generating substrate in the atomization chamber, thereby improving the atomization effect of the aerosol-generating substrate.

[0068] In one possible design, the microwave introduction part includes: a first introduction member, which is arranged on the side wall of the shell and is connected to the microwave emission source; a second introduction member, the first end of the second introduction member is connected to the first introduction member, the second introduction member is located in the resonant cavity, and the second end of the second introduction member faces the bottom wall of the resonant cavity.

[0069] In this design, the microwave introduction section includes a first introduction member and a second introduction member. The first introduction member is positioned through the side wall of the housing. The first end of the first introduction member is connected to a microwave emission source, allowing microwaves generated by the microwave emission source to enter the microwave introduction section through the first end of the first introduction member. The second end of the first introduction member is connected to the first end of the second introduction member, and the second end of the second introduction member faces the bottom wall of the resonant cavity. After passing through the first and second introduction members, the microwaves are conducted from the bottom wall of the resonant cavity to the atomization chamber, thereby heating and atomizing the aerosol-generating substrate in the atomization chamber.

[0070] The first inlet is coaxially arranged with the microwave output end of the microwave emission source. The second inlet comprises a horizontal inlet portion and a vertical inlet portion. The axis of the horizontal inlet portion is parallel to the bottom wall of the resonant cavity, while the axis of the vertical inlet portion is perpendicular to the bottom wall of the resonant cavity. The horizontal inlet portion is connected to the vertical inlet portion via a bend and is coaxially arranged with the first inlet portion. This arrangement of the microwave inlet ensures that all microwaves generated by the microwave emission source enter the resonant cavity and are conducted within the resonant cavity through the resonant column.

[0071] In a possible design, the aerosol generating device further includes: a recessed portion, which is arranged on the bottom wall of the resonant cavity, and the second end of the second introduction portion is located in the recessed portion.

[0072] In this design, the aerosol generating device also includes a recessed portion, which is arranged on the bottom wall of the resonant cavity, and the recessed portion is arranged opposite to the second end of the second introduction portion, and the second end of the second introduction portion extends into the recessed portion, so that the microwaves entering the resonant cavity can be conducted along the direction from the second end to the first end of the resonant column, thereby reducing energy loss during microwave conduction.

[0073] In a possible design, the microwave introduction part includes: a third introduction member, which is arranged on the side wall of the shell, wherein 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 column.

[0074] In this design, the microwave introduction part also includes a third introduction member, which is coaxially arranged with the microwave output end of the microwave emission source, with a first end of the third introduction member connected to the microwave emission source, and a second end of the third introduction member facing the resonant column. By coaxially arranging the third introduction member with the microwave output end of the microwave emission source and connecting the third introduction member to the resonant column, the microwave is directly conducted to the resonant column, so that all the microwaves output by the microwave emission source enter the resonant cavity.

However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0090] Refer to the following Figures 1 to 10 An aerosol-generating device according to some embodiments of the present application is described.

[0091] like Figure 1 and Figure 3 As shown, an embodiment of the present application provides an aerosol generating device 100 , including: a housing 110 , a microwave assembly 130 , a mounting portion 140 and a pressure sensor 150 .

[0092] The housing 110 includes a resonant cavity 120;

[0093] The microwave component 130 is disposed in the housing 110 and is used to feed microwaves into the resonant cavity 120 ;

[0096] This embodiment provides an aerosol-generating device 100 comprising a housing 110, a microwave assembly 130, a mounting portion 140, and a pressure sensor 150. A resonant cavity 120 is disposed within the housing 110.

The atomization cavity 143 is used to accommodate an aerosol-generating substrate. The microwave assembly 130 feeds into the resonant cavity 120, and the microwaves are transmitted through the resonant cavity 120 to the mounting portion 140, thereby heating the aerosol-generating substrate within the atomization cavity 143 with microwaves.

[0097] The mounting portion 140 isolates the resonant cavity 120 and the atomizing cavity 143 from each other, thereby preventing liquid waste or solid waste generated after the aerosol generating matrix in the atomizing cavity 143 is atomized from entering the resonant cavity 120 , thereby preventing the aerosol generating device 100 from malfunctioning due to the waste entering the resonant cavity 120 .

[0098] The aerosol generating device 100 also includes a pressure sensor 150. The collection end of the pressure sensor 150 is connected to the atomizing chamber 143. The pressure sensor 150 is capable of collecting the air pressure value within the atomizing chamber 143. The pressure sensor 150 is disposed in the housing 110 and is located outside the resonant cavity 120. The pressure sensor 150 is not affected by the microwaves transmitted through the resonant cavity 120. The pressure sensor 150 collects the changes in the air pressure value within the atomizing chamber 143. Based on the changes in the air pressure value within the atomizing chamber 143, it can be detected whether the aerosol generating device 100 is in the inhalation state. The operation of the microwave assembly 130 is controlled based on the inhalation state of the aerosol generating device 100.

[0099] In some embodiments, when the aerosol-generating device 100 is detected to be in the inhalation state, the microwave assembly 130 is controlled to operate, thereby performing microwave heating and atomization on the aerosol-generating substrate in the atomization chamber 143. When the aerosol-generating device 100 is not in the inhalation state, the microwave assembly 130 is controlled to stop operating and does not continue to heat and atomize the aerosol-generating substrate in the atomization chamber 143.

[0100] In some other embodiments, the aerosol generating device 100 is in the on state and receives a preheating control instruction, and controls the microwave component 130 to operate at a first power until the cavity temperature value of the atomizing cavity 143 enters the set temperature value range, so that the cavity temperature value is maintained within the set temperature value range, which can play a role in preheating the aerosol generating matrix in the atomizing cavity 143. Detect whether the aerosol generating device is in the suction state, and adjust the first power according to the suction state of the aerosol generating device. Specifically, if it is detected that the aerosol generating device 100 is in the suction state, the microwave component 130 is controlled to operate at a second power, thereby quickly increasing the temperature in the atomizing cavity 143, so that the aerosol generating matrix is ​​quickly heated and atomized to produce an aerosol, wherein the second power is greater than the first power. If it is detected that the aerosol generating device 100 is not in the suction state, the microwave component 130 is controlled to maintain the first power operation and continue to preheat the aerosol generating matrix.

[0101] The present application collects the air pressure value in the atomization chamber 143 through the pressure sensor 150, thereby detecting whether the aerosol generating device 100 is in the puffing state, and controlling the operation of the microwave component 130 according to the puffing state. After the user stops puffing, the microwave component 130 can be promptly controlled to stop operating, thereby avoiding the waste of electrical energy and the aerosol generating matrix, and achieving the preheating effect of the aerosol generating matrix when the aerosol generating device is in the non-puffing state. In the puffing state, the aerosol generating matrix can be quickly heated to the atomization temperature, reducing energy consumption while improving the atomization efficiency of the aerosol generating matrix, and also improving the atomization degree of the aerosol generating matrix, thereby improving the user experience.

[0102] In addition, the aerosol generating device 100 according to the above technical solution provided by this application may also have the following additional technical features:

[0103] like Figure 1 and Figure 3 As shown in any of the above embodiments, the mounting portion 140 includes a base 141 , a conducting member 142 and an atomizing chamber 143 .

[0104] The atomizing chamber 143 is disposed in the base body 141;

[0105] One end of the conductive member 142 is connected to the base 141 and communicates with the atomization chamber 143 , and the other end of the conductive member 142 is connected to the collecting end of the pressure sensor 150 .

[0106] In this embodiment, the mounting portion 140 includes a seat body 141 and a conductive member 142. The seat body 141 is arranged in the housing 110, and the seat body 141 and the atomizing chamber 143 enclose a resonant cavity 120. The conductive member 142 is provided in the housing 110, one end of the conductive member 142 is connected to the seat body 141, and the conductive member 142 is connected to the atomizing chamber 143, and the other end of the conductive member 142 extends to the outside of the housing 110 and is connected to the pressure sensor 150. The atomizing chamber 143 is connected to the pressure sensor 150 outside the housing 110 through the conductive member 142, so that the pressure sensor 150 can directly collect the cavity pressure value of the atomizing chamber 143.

[0107] like Figure 1 As shown, in any of the above embodiments, the conducting member 142 includes: a first pipe member 1422 and a second pipe member 1424 .

[0108] The first tube 1422 is integrally formed with the base body 141;

[0109] The second pipe 1424 is disposed in the housing 110 , and a first end of the second pipe 1424 passes through the housing 110 and is connected to the first pipe 1422 . A second end of the second pipe 1424 is connected to the pressure sensor 150 , and a collection end of the pressure sensor 150 is located in the second pipe 1424 .

[0110] In this embodiment, the conductive member 142 includes a first tube 1422 and a second tube 1424. The first tube 1422 is connected to the base 141. The second tube 1424 is disposed on the side wall of the housing 110 and extends through the housing 110 to connect to the first tube 1422. The end of the second tube 1424 located outside the housing 110 is connected to the pressure sensor 150. Arranging the conductive member 142 to connect the first tube 1422 and the second tube 1424 simplifies the assembly process of the aerosol-generating device 100 and facilitates the separate disassembly and cleaning of the mounting portion 140.

[0111] The first pipe 1422 is integrally formed with the base 141, further reducing the number of assembly steps. The second pipe 1424 is mounted on the housing 110 via a fixing member, which may be a screw, rivet or other fastener.

[0112] The steps of assembling the conductive member 142 and the mounting portion 140 include: inserting the base body 141 integrally formed with the first tube 1422 into the interior of the housing 110. The second tube 1424 is inserted into the side wall of the housing 110, and the second tube 1424 is plugged and connected to the first tube 1422, so that the first tube 1422 and the second tube 1424 are connected to the atomization chamber 143 in the base body 141, and the sealing performance of the connection between the first tube 1422 and the second tube 1424 is ensured. The second tube 1424 is fixed to the side wall of the housing 110 by fasteners, thereby completing the assembly process of the conductive member 142 and the mounting portion 140. By respectively arranging the first tube 1422 and the second tube 1424 inside and outside the housing 110, and then connecting the first tube 1422 and the second tube 1424 to each other, the assembly steps of the conductive member 142 can be simplified while ensuring the sealing performance of the conductive member 142.

[0113] 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 and communicates with the atomization chamber 143 . The opening is used to allow the aerosol-generating substrate to enter the atomization chamber 143 .

[0114] In this embodiment, the mounting portion 140 further includes an opening disposed at one end of the base body 141, the opening facing the exterior of the housing 110. The opening is communicated with the atomization chamber 143, for inserting the aerosol-generating substrate into the atomization chamber 143 through the opening.

[0115] It is understandable that the aerosol generating substrate is provided with a suction portion, which protrudes out of the atomization cavity 143 through the opening, and the user can inhale the aerosol generating substrate through the suction portion.

[0116] like Figure 3 As shown, in any of the above embodiments, the aerosol generating device 100 further includes a first through hole 160 .

[0117] The first through hole 160 is provided in the housing 110 , and the resonant cavity 120 is connected to the outside of the cavity through the first through hole 160 ;

[0118] The mounting portion 140 further includes a second through hole 144 disposed on the base body 141 . The atomization cavity 143 is connected to the resonance cavity 120 through the second through hole 144 .

[0119] 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 to connect the resonant cavity 120 with the exterior of the housing 110, and the second through hole 144 is provided in the base 141 to connect the resonant cavity 120 with the atomizing cavity 143. When the user inhales through the suction part of the aerosol generating matrix, the gas outside the shell 110 flows through the first through hole 160, the resonance cavity 120, the second through hole 144, the atomization cavity 143, and the aerosol generating matrix in sequence. The heated precipitate of the aerosol generating matrix mixes with the gas to form an aerosol, and the formed aerosol is discharged from the suction part, thereby forming a gas flow channel. During the suction process of the aerosol generating matrix, the air outside the shell 110 can be continuously replenished into the atomization cavity 143, so that the aerosol generating matrix can be fully atomized. It can also avoid the aerosol generating matrix's suction resistance being too large due to too small airflow, thereby improving the user experience.

[0120] like Figure 4 and Figure 5 As shown, in any of the above embodiments, the mounting portion 140 further includes at least two protrusions 145 .

[0121] At least two protrusions 145 are provided on the inner side wall of the atomization chamber 143 , the at least two protrusions 145 protrude from the inner side wall of the atomization chamber 143 , a gap is provided between two adjacent protrusions 145 of the at least two protrusions 145 , and the at least two protrusions 145 are used to fix the aerosol generating matrix.

[0122] In this embodiment, the mounting portion 140 further includes at least two protrusions 145 disposed on the inner sidewall of the atomization chamber 143. These at least two protrusions 145 secure the aerosol-generating substrate. The aerosol-generating substrate is inserted into the atomization chamber 143 through the opening, and the at least two protrusions 145 abut against the outer sidewall of the aerosol-generating substrate to secure the aerosol-generating substrate and prevent it from slipping out of the atomization chamber 143.

[0123] Two adjacent protrusions 145 of the at least two protrusions 145 are spaced apart from each other, and the gap between the two adjacent protrusions 145 and the space between the aerosol generating substrate and the side wall of the atomization chamber 143 form an air flow channel.

[0124] When a user draws in air through the suction portion of the aerosol-generating matrix, the gas outside the housing 110 flows sequentially through the gap between two adjacent protrusions 145, the gap between the aerosol-generating matrix and the sidewall of the atomizing chamber 143, and the aerosol-generating matrix. The heated precipitate of the aerosol-generating matrix mixes with the gas to form an aerosol, which is then discharged from the suction portion. This ensures that during the aerosol-generating matrix drawing process, air outside the housing 110 can continuously be replenished and enter the atomizing chamber 143, allowing the aerosol-generating matrix to be fully atomized. This also prevents excessive airflow from causing excessive inhalation resistance of the aerosol-generating matrix, thereby improving the user experience.

[0125] In any of the above embodiments, at least two protrusions 145 are located on the inner sidewall of the atomizing chamber 143 near the opening, and the at least two protrusions 145 are evenly distributed along the circumference of the atomizing chamber 143 .

[0126] In this embodiment, at least two protrusions 145 are evenly arranged along the axial direction of the atomizing chamber 143. The evenly distributed protrusions 145 can effectively fix the aerosol-generating substrate, preventing the aerosol-generating substrate from falling out of the atomizing chamber 143 during the puffing process. The aerosol-generating substrate is produced during the puffing process. The at least two protrusions 145 are arranged near one end of the opening to facilitate the user to clean the waste attached to the protrusions 145, preventing the waste from blocking the gaps between the protrusions 145, thereby improving the operational stability of the aerosol-generating device 100.

[0127] like Figure 6 and Figure 7 As shown, in any of the above embodiments, the mounting portion 140 further includes a groove 146 .

[0128] The groove 146 is disposed on the inner wall of the atomizing chamber 143 , and extends along the center line of the atomizing chamber 143 .

[0129] In this embodiment, the mounting portion 140 further includes a groove 146 provided on the inner sidewall of the atomization chamber 143. After the aerosol-generating substrate is inserted into the atomization chamber 143 through the opening, the aerosol-generating substrate contacts the inner sidewall of the atomization chamber 143. The friction between the inner sidewall of the atomization chamber 143 and the aerosol-generating substrate can prevent the aerosol-generating substrate from falling out of the atomization chamber 143.

[0130] When a user draws in air through the suction portion of the aerosol-generating matrix, gas outside the housing 110 flows sequentially through the groove 146 and the aerosol-generating matrix. The heated precipitate from the aerosol-generating matrix mixes with the gas to form an aerosol, which is then discharged from the suction portion. This ensures that during the inhalation of the aerosol-generating matrix, air outside the housing 110 can continuously be replenished and re-entered into the atomization chamber 143, allowing the aerosol-generating matrix to be fully atomized. This also prevents excessive airflow from causing excessive inhalation resistance of the aerosol-generating matrix, thereby improving the user experience.

[0131] In any of the above embodiments, the number of the grooves 146 is at least two, and the at least two grooves 146 are evenly distributed along the circumference of the atomization chamber 143 .

[0132] In this embodiment, multiple grooves 146 are evenly distributed on the inner side wall of the atomization chamber 143, so that the external air can evenly contact the aerosol generating matrix, and the precipitate of the aerosol generating matrix can be fully mixed with the air to form an aerosol, thereby improving the atomization effect of the aerosol generating matrix.

[0133] It is understandable that a reasonable setting of the number and inner diameter of the grooves 146 can adjust the draw resistance of the aerosol generating device 100 .

[0134] like Figure 8 and Figure 9 As shown, in any of the above embodiments, the mounting portion 140 further includes an isolation member 147 .

[0135] The isolation member 147 is disposed in the atomization chamber 143 , and the isolation member 147 divides the atomization chamber 143 into a first cavity 1432 and a second cavity 1434 . The first cavity 1432 is connected to the second cavity 1434 , and the first cavity 1432 is used to accommodate the aerosol generating substrate.

[0136] In this embodiment, the mounting portion 140 also includes an isolation member 147 disposed in the atomization chamber 143. The isolation member 147 separates the atomization chamber 143 into a first cavity 1432 and a second cavity 1434 that are interconnected. The first cavity 1432 is used to accommodate the aerosol generating matrix, and the second cavity 1434 is connected to the air outside the atomization chamber 143.

[0137] When a user draws in air through the suction portion of the aerosol-generating matrix, air outside the housing 110 flows sequentially through the second cavity 1434, the first cavity 1432, and the aerosol-generating matrix. That is, the air passes through the second cavity 1434 and enters the first cavity 1432, where it comes into contact with the aerosol-generating matrix. The heated precipitate from the aerosol-generating matrix mixes with the gas to form an aerosol, which is then discharged from the suction portion. This ensures that during the inhalation process of the aerosol-generating matrix, air outside the housing 110 can continuously be replenished and re-entered into the atomization cavity 143, allowing the aerosol-generating matrix to be fully atomized. This also prevents excessive inhalation resistance of the aerosol-generating matrix due to insufficient airflow, thereby improving the user experience.

[0138] In any of the above embodiments, the first cavity 1432 and the second cavity 1434 are coaxially distributed in an annular shape, and the second cavity 1434 is located outside the first cavity 1432 .

[0139] In this embodiment, the second cavity 1434 is annularly arranged outside the first cavity 1432, so that the air flows through the second cavity 1434 and then enters the first cavity 1432 evenly from the outside, thereby achieving that the external air can be evenly in contact with the aerosol generating matrix, so that the precipitate of the aerosol generating matrix can be fully mixed with the air to form an aerosol, thereby improving the atomization effect of the aerosol generating matrix.

[0140] In any of the above embodiments, the mounting portion 140 further includes a third through hole.

[0141] The third through hole is provided in the isolation member 147 , and is located at one end of the isolation member 147 connected to the bottom wall of the atomization chamber 143 .

[0142] In this embodiment, the mounting portion 140 further includes a third through hole. The third through hole is provided in the isolation member 147, and the first cavity 1432 is connected to the second cavity 1434 through the third through hole.

[0143] In any of the above embodiments, the mounting portion 140 further includes a supporting portion.

[0144] The supporting portion is disposed on the bottom wall of the atomizing chamber 143 , and the supporting portion protrudes from the bottom wall of the atomizing chamber 143 .

[0145] In this embodiment, the mounting portion 140 further includes a support portion disposed on the bottom wall of the atomization chamber 143. The support portion is used to support 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 contact the bottom end of the aerosol-generating substrate, further improving the mixing effect between the air and the heated precipitates of the aerosol-generating substrate, allowing the precipitates of the aerosol-generating substrate to fully mix with the air to form an aerosol, thereby improving the atomization effect of the aerosol-generating substrate.

[0146] In any of the above embodiments, the housing 110 includes a body 112 and an end cover 114 .

[0147] The end cover 114 is detachably connected to the body 112 . The mounting portion 140 is disposed through the end cover 114 . The end cover 114 and the body 112 enclose a resonant cavity 120 .

[0148] In this embodiment, the housing 110 includes a body 112 and an end cap 114. The mounting portion 140 is disposed on the end cap 114. The end cap 114 is detachably connected to the body 112, allowing the user to remove the end cap 114 to clean the mounting portion 140 separately, thereby avoiding water ingress during cleaning of the entire aerosol generating device 100.

[0149] In any of the above embodiments, the aerosol generating device 100 further includes a resonant column 170 .

[0150] The resonant column 170 is disposed in the resonant cavity 120 . The first end of the resonant column 170 is connected to the bottom wall of the resonant cavity 120 , and the second end of the resonant column 170 is disposed opposite to the mounting portion 140 .

[0151] In this embodiment, resonant column 170 is used to resonate and conduct microwaves. A first end of resonant column 170 is connected to the bottom wall of resonant cavity 120, and a second end of resonant column 170 is disposed opposite mounting portion 140. Microwaves fed into resonant cavity 120 by microwave assembly 130 are conducted along the first end to the second end of resonant column 170, thereby heating the aerosol-generating substrate within atomization cavity 143 of mounting portion 140 through microwaves.

[0152] The atomization cavity 143 and the resonance cavity 120 are isolated from each other by the mounting portion 140 , which can prevent liquid waste or fixed waste generated after the aerosol generating matrix in the atomization cavity 143 is atomized from entering the resonance cavity 120 , thereby preventing the microwave component 130 from malfunctioning due to the waste entering the resonance cavity 120 .

[0153] In some embodiments, the inner wall of the resonant cavity 120 and the resonant column 170 are made of a conductive material, which may be a metal material, such as gold, copper, or silver.

[0154] In some embodiments, the inner wall of the resonant cavity 120 and the outer wall of the resonant column 170 are provided with a conductive coating, and the conductive coating is selected to be a metal coating, such as a gold plating layer, a copper plating layer, or a silver plating layer.

[0155] In these embodiments, metals with high stability and good conductivity are selected to set the resonant cavity 120 and the resonant column 170, which not only prevents microwave leakage, but also prevents the inner wall of the resonant cavity 120 and the resonant column 170 from rusting.

[0156] In some embodiments, the portion of the mounting portion 140 located within the resonant cavity 120 is made of a low dielectric loss material, such as PTFE (polytetrafluoroethylene), glass, or ceramic, to allow microwaves to be transmitted to the atomization cavity 143 within the mounting portion 140 , thereby heating the aerosol-generating substrate in the atomization cavity 143 with microwaves to generate aerosol.

[0157] In some embodiments, the mounting portion 140 is detachably connected to the housing 110 .

[0158] In these embodiments, the atomization chamber 143 for accommodating the aerosol generating substrate is disposed in the mounting portion 140 . The atomization chamber 143 can be separately disassembled and cleaned by disassembling the mounting portion 140 , thereby improving the user experience.

[0159] like Figure 1 and Figure 2 As shown, in any of the above embodiments, the resonant column 170 and the mounting portion 140 are spaced apart.

[0160] In this embodiment, by setting a gap between the resonant column 170 and the mounting portion 140, it is possible to avoid squeezing the resonant column 170 during the assembly of the mounting portion 140 into the housing 110, thereby reducing the production and assembly accuracy requirements for the resonant column 170 and the mounting portion 140.

[0161] like Figure 1 As shown, in any of the above embodiments, the aerosol generating device 100 further includes: a fixing portion 180 disposed on the mounting portion 140 and located in the resonant cavity 120 , the fixing portion 180 includes a limiting cavity, and at least a portion of the resonant column 170 is located in the limiting cavity.

[0162] In this embodiment, the aerosol generating device 100 also includes a fixing portion 180 arranged on the mounting portion 140, and a limiting cavity is provided in the fixing portion 180. At least a portion of the resonance column 170 is located in the limiting cavity. The fixing portion 180 fixes the resonance column 170 through the limiting cavity, thereby playing a certain anti-vibration role on the resonance column 170 and preventing the resonance column 170 from falling off due to vibration.

[0163] In some embodiments, the fixing portion 180 and the mounting portion 140 are integrally formed.

[0164] In these embodiments, the fixing portion 180 and the mounting portion 140 are integrally formed and have a high bonding strength, thereby improving the stabilizing effect of the fixing portion 180 on the resonant column 170 .

[0165] like Figure 1 and Figure 2 As shown, in any of the above embodiments, the axis of the atomization chamber 143 is coaxial with the axis of the resonant column 170 .

[0166] In this embodiment, the atomization chamber 143 and the resonance column 170 are coaxially arranged to ensure that the microwaves transmitted to the atomization chamber 143 through the resonance column 170 can be transmitted to the middle position of the atomization chamber 143, thereby improving the uniformity of microwave heating of the aerosol generating matrix in the atomization chamber 143, avoiding uneven heating of the aerosol generating matrix caused by the concentration of microwaves in the atomization chamber 143, and further improving the atomization effect of the aerosol generating matrix.

[0167] like Figure 1 and Figure 2 As shown, in any of the above embodiments, the microwave assembly 130 includes a microwave introduction portion 132 .

[0168] The microwave introduction portion 132 is provided on the side wall of the shell 110 and is connected to the resonant cavity 120; the microwave emission source 134 is connected to the microwave introduction portion 132, and the microwaves output by the microwave emission source 134 are fed into the resonant cavity 120 through the microwave introduction portion 132, so that the microwaves are transmitted along the direction from the first end of the resonant column 170 to the second end of the resonant column 170.

[0169] In this embodiment, microwave assembly 130 includes a microwave emission source 134 and a microwave introduction portion 132. Microwave emission source 134 is used to generate microwaves, and microwave introduction portion 132, located on the sidewall of housing 110, is used to transmit the microwaves generated by microwave emission source 134 into resonant cavity 120. After being fed into resonant cavity 120 through microwave introduction portion 132, the microwaves are transmitted along the direction from the first end of resonant column 170 to the second end of resonant column 170, allowing the microwaves to directly act on the aerosol generating substrate in atomization cavity 143, thereby improving the atomization effect of the aerosol generating substrate.

[0170] like Figure 1 As shown, in any of the above embodiments, the microwave introduction portion 132 includes a first introduction member 1322 and a second introduction member 1324 .

[0171] The first introduction member 1322 is disposed on the side wall of the housing 110 , and the first introduction member 1322 is connected to the microwave emission source 134 ;

[0172] A first end of the second introducing member 1324 is connected to the first introducing member 1322 . The second introducing member 1324 is located in the resonant cavity 120 , and a second end of the second introducing member 1324 faces the bottom wall of the resonant cavity 120 .

[0173] In this embodiment, microwave introduction portion 132 includes a first introduction member 1322 and a second introduction member 1324. First introduction member 1322 is disposed through the side wall of housing 110. The first end of first introduction member 1322 is connected to microwave emission source 134, allowing microwaves generated by microwave emission source 134 to enter microwave introduction portion 132 through the first end of first introduction member 1322. The second end of first introduction member 1322 is connected to the first end of second introduction member 1324, and the second end of second introduction member 1324 faces the bottom wall of resonant cavity 120. After passing through first introduction member 1322 and second introduction member 1324, microwaves are conducted from the bottom wall of resonant cavity 120 to atomization cavity 143, thereby heating and atomizing the aerosol-generating substrate within atomization cavity 143.

[0174] The first inlet is coaxially arranged with the microwave output end of microwave emission source 134. The second inlet comprises a horizontal inlet portion and a vertical inlet portion. The axis of the horizontal inlet portion is parallel to the bottom wall of resonant cavity 120, while the axis of the vertical inlet portion is perpendicular to the bottom wall of resonant cavity 120. The horizontal inlet portion is connected to the vertical inlet portion via a bend and is coaxially arranged with the first inlet portion. This arrangement of microwave inlet portion 132 ensures that all microwaves generated by microwave emission source 134 enter resonant cavity 120 and are conducted within resonant cavity 120 via resonant column 170.

[0175] like Figure 2 As shown, in any of the above embodiments, the aerosol generating device 100 further includes a recessed portion 190 .

[0176] The recessed portion 190 is disposed on the bottom wall of the resonant cavity 120 , and the second end of the second introduction portion is located in the recessed portion 190 .

[0177] In this embodiment, the aerosol generating device also includes a recessed portion 190, which is arranged on the bottom wall of the resonant cavity 120, and the recessed portion 190 is arranged opposite to the second end of the second inlet portion, and the second end of the second inlet portion extends into the recessed portion 190, so that the microwaves entering the resonant cavity 120 can be conducted along the direction from the second end to the first end of the resonant column 170, thereby reducing energy loss during microwave conduction.

[0178] like Figure 10 As shown, in any of the above embodiments, the microwave introduction portion 132 includes a third introduction member 1326 .
