Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and more specifically, to an aerosol generating device. Background Technology

[0002] Currently, most aerosol generating devices in related technologies heat the aerosol generating matrix using heating wires and ceramics to atomize the matrix and produce the desired aerosol. However, this method of atomizing the aerosol generating matrix using heating wires and ceramics can lead to issues such as burnt smells or safety concerns. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, the present invention provides an aerosol generating device.

[0005] In view of this, the present invention proposes an aerosol generating device, comprising: a housing, the housing including a liquid storage chamber for containing an aerosol generating matrix; a liquid guiding component disposed within the housing, the liquid guiding component including a liquid guiding section and an atomizing section communicating with each other, the atomizing section forming an atomizing cavity inside, the liquid guiding section communicating with the liquid storage chamber, the liquid guiding section being used to transfer the aerosol generating matrix to the atomizing section; and a microwave assembly including a microwave introducing section, at least a portion of the microwave introducing section being disposed within the atomizing cavity, the microwave introducing section being used to feed microwaves into the atomizing cavity.

[0006] The aerosol generating device provided by this invention includes a housing, a liquid guiding component, and a microwave assembly. The housing includes a liquid storage chamber containing an aerosol generating matrix. The liquid guiding component is disposed within the housing and includes a liquid guiding section and an atomizing section communicating with each other. The microwave assembly includes a microwave introducing section. The liquid guiding section can transfer the aerosol generating matrix from the liquid storage chamber to the atomizing section. At least a portion of the microwave introducing section extends into the atomizing chamber to feed microwaves into the microwave chamber. Under the action of microwaves, the aerosol generating matrix absorbs microwave energy, and high-frequency friction occurs between the polar molecules within it, generating heat. This heats the aerosol generating matrix, achieving atomization of the aerosol generating matrix for suction. In the technical solution proposed in this application, the heating of the aerosol generating matrix is ​​achieved by microwaves, which can ensure that the temperature of each part of the aerosol generating matrix remains consistent, avoid carbonization of the aerosol generating matrix due to high temperature, and thus avoid the burnt taste that occurs when heating the aerosol generating matrix with heating wires or ceramics in related technologies, thereby improving the smoking experience.

[0007] The microwave inlet extends into the atomization chamber, directly feeding microwaves into it. On one hand, the microwaves atomize the aerosol-generating matrix, preventing a burnt taste from affecting the vaping experience. On the other hand, extending the microwave inlet into the atomization chamber increases its size, providing more space for the atomized aerosol-generating matrix and thus increasing the atomization volume. Furthermore, the microwaves fed in by the inlet act directly on the atomization chamber, ensuring effective microwave atomization.

[0008] It is understandable that when microwaves act on the aerosol generating matrix, the aerosol generating matrix absorbs microwave energy, causing high-frequency friction between the polar molecules inside it to generate heat, thereby heating the aerosol generating matrix and causing it to atomize.

[0009] The aerosol generating apparatus provided by the present invention may further have the following additional technical features:

[0010] In one possible design, the atomizing section further includes: an atomizing surface that encloses an atomizing cavity, and a liquid guiding section for conveying an aerosol-generating matrix to the atomizing surface.

[0011] In this design, the atomizing section also includes an atomizing surface that surrounds the atomizing cavity. The liquid guiding section then guides the aerosol generating matrix in the liquid storage cavity toward the atomizing section, so that the aerosol generating matrix is ​​distributed on the atomizing surface. In this way, under the action of the microwave fed by the microwave inlet section, the aerosol generating matrix on the atomizing surface is atomized for suction.

[0012] In practical applications, the atomizing chamber is a hollow cylinder.

[0013] In one possible design, the liquid guiding part further includes a liquid guiding surface that blocks the outlet of the liquid storage cavity.

[0014] In this design, the liquid guiding section includes a liquid guiding surface that blocks the outlet of the liquid storage chamber. This ensures that the liquid guiding surface is in complete contact with the aerosol generating matrix in the liquid storage chamber. Under the action of the liquid guiding section, the aerosol generating matrix in the liquid storage chamber can flow into the atomization chamber, thereby allowing the aerosol generating matrix on the atomization surface to be heated by microwaves and atomized for suction. On the other hand, it also prevents the aerosol generating matrix in the liquid storage chamber from flowing to other components and affecting the use of the aerosol generating device.

[0015] Understandably, the liquid storage chamber includes an outlet through which the aerosol-generating matrix can be transferred to the liquid guiding component.

[0016] Furthermore, a connector is provided at the outlet of the liquid storage chamber, and a liquid outlet is provided on the connector. The liquid guiding surface blocks the liquid outlet, so that the liquid guiding surface can directly contact the aerosol at the liquid outlet to form a matrix. Then, under the action of the liquid guiding part, the aerosol matrix flows to the atomizing part.

[0017] In one possible design, the liquid guiding component is made of a porous material, and the liquid guiding part and the atomizing part are integrally formed.

[0018] In this design, the liquid guiding component is made of porous material, which has good adsorption properties, thus enabling the aerosol generating matrix to be transported to the atomizing section. The liquid guiding component and the atomizing section are integrally formed, which improves the connection strength between the liquid guiding component and the atomizing section, and also ensures that the liquid guiding component can transport the aerosol generating matrix in the liquid storage chamber to the atomizing section.

[0019] In one possible design, the fluid guiding element is further made of porous ceramic, cotton, or fiber.

[0020] In this design, the liquid guiding component is made of porous ceramic, cotton, or fiber. Porous ceramic, cotton, and fiber all have good adsorption properties. The liquid guiding component is in direct contact with the aerosol matrix in the liquid storage chamber. It can transfer the liquid in the liquid storage chamber to the atomizing part through capillary force, so that the aerosol matrix on the atomizing part absorbs microwave energy and atomizes for suction.

[0021] In one possible design, the liquid guiding section and the atomizing section are separate components. The atomizing section is made of porous material or a substrate with a microporous array of through holes. The liquid guiding section has a liquid guiding channel to transfer the aerosol generating matrix from the liquid storage chamber to the atomizing section.

[0022] In this design, the liquid guiding section and the atomizing section are independent components, which facilitates the manufacturing and replacement of the liquid guiding section and the atomizing section. The liquid guiding section has a liquid guiding channel, which transfers the aerosol generating matrix in the liquid storage chamber to the atomizing section, where it is atomized under the action of microwaves introduced by the microwave inlet section for suction.

[0023] The atomizing section is made of porous material or a substrate with a microporous array. Porous materials have good adsorption properties, ensuring that the atomizing section can adsorb a large amount of aerosol generation matrix, thereby increasing the atomization volume of the aerosol generating device. A substrate with a microporous array also has good adsorption properties; therefore, setting the atomizing section to a substrate with a microporous array also allows for the adsorption of a large amount of aerosol generation matrix, thus improving the atomization effect.

[0024] In one possible design, the microwave assembly further includes: a conductor connected to the housing, a microwave inlet disposed within the conductor and enclosing a microwave cavity with the conductor, and at least a portion of the atomizing part located within the microwave cavity.

[0025] In this design, the microwave assembly also includes a conductor connected to the housing. A microwave inlet is disposed within the conductor, thus connecting the microwave assembly to the housing. The microwave inlet, located within the conductor, encloses a microwave cavity, allowing microwaves to be fed into the cavity during operation. This confines the microwaves within the cavity, preventing leakage and thus reducing microwave loss, thereby improving the energy utilization rate of the microwave assembly. Simultaneously, at least a portion of the atomization cavity is located within the microwave cavity, enabling the aerosol generation matrix to effectively absorb the microwaves within the cavity, generating heat and atomizing the matrix. This ensures the atomization effect of the aerosol generation matrix within the microwave cavity.

[0026] It is understandable that the conductor and the microwave assembly form a microwave cavity, where the conductor acts as a shield for microwaves, thereby preventing microwave leakage and improving the safety performance of the aerosol generation matrix.

[0027] Furthermore, the conductor is in the form of a hollow cylinder.

[0028] In one possible design, the conductor further includes: a first sleeve connected to the housing, the first sleeve having an air inlet communicating with the atomizing chamber; and a second sleeve located inside the first sleeve, the microwave inlet located inside the second sleeve, and forming a microwave cavity with a portion of the inner wall of the second sleeve.

[0029] In this design, the conductor includes a first sleeve and a second sleeve. The first sleeve is connected to the housing, connecting the microwave component to the housing. The first sleeve has an air inlet, through which air enters the atomization chamber, carrying the atomized aerosol matrix out of the housing for suction. The second sleeve is disposed inside the first sleeve, forming a microwave cavity with the microwave inlet, thus shielding the microwaves, preventing leakage, and improving the safety of the aerosol matrix. At least a portion of the atomization chamber is located within the microwave cavity, ensuring effective atomization of the aerosol matrix within the chamber, thereby improving the suction experience.

[0030] In one possible design, the microwave inlet is further arranged coaxially with the second sleeve.

[0031] In this design, the microwave inlet and the second sleeve are coaxially arranged, which avoids uneven heating of the aerosol generation matrix caused by the concentration of microwaves in the microwave cavity. This ensures that the microwave energy is uniform at all positions in the microwave cavity, thereby ensuring that the aerosol generation matrix at all points on the atomization surface can absorb microwave energy and atomize, further improving the atomization effect of the aerosol generation matrix.

[0032] Understandably, the microwave inlet is cylindrical, and the second sleeve is also a hollow cylinder.

[0033] Furthermore, the atomizing cavity, the microwave inlet, and the second sleeve are all coaxially arranged.

[0034] In one possible design, the second sleeve further includes: a first cavity, the inner wall of which and the microwave inlet portion enclose a microwave cavity; and a second cavity, which is connected to the first cavity, the second cavity being located on the side of the first cavity away from the liquid guide, the second cavity being provided with an insulating element, and the microwave inlet portion passing through the insulating element.

[0035] In this design, the second sleeve includes a first cavity and a second cavity. The inner wall of the first cavity and the microwave inlet portion enclose a microwave cavity, thereby enabling microwave energy to be present in the microwave cavity. An insulating component is provided in the second cavity to achieve an insulated connection between the microwave inlet portion and the second sleeve, thereby reducing microwave loss.

[0036] It is understandable that the first cavity and the second cavity are distributed along the axial direction of the second sleeve. The second cavity is located on the side of the first cavity away from the liquid guiding element.

[0037] In one possible design, the first and second sleeves are further made of metal.

[0038] In this design, the first and second sleeves are made of metal, which enables both power supply and microwave shielding to prevent microwave leakage.

[0039] Furthermore, both the first and second sleeves are made of metal, which prevents microwave leakage from both sleeves, thereby improving the safety of the aerosol generating device.

[0040] In practical applications, the housing is made of metal or has a metal layer on its inner wall, which enables the housing to shield microwaves and further prevent microwave leakage.

[0041] In one possible design, the microwave assembly further includes: a microwave emitting source connected to the input terminal of the microwave inlet; and a power supply unit for supplying power to the microwave emitting source.

[0042] In this design, the microwave assembly also includes a microwave transmitter and a power supply. The microwave transmitter is connected to the input terminal of the microwave inlet. The microwave transmitter generates microwaves, which are then conducted into the atomization cavity through the microwave inlet, thereby atomizing the aerosol matrix within the atomization cavity. The power supply is connected to the microwave transmitter to provide power, enabling the microwave transmitter to generate microwaves when powered on.

[0043] Furthermore, the power supply component is connected to the second sleeve; specifically, the power supply component is detachably connected to the second sleeve.

[0044] In one possible design, the housing further includes a mounting cavity, within which at least a portion of the microwave assembly and a liquid guide are disposed.

[0045] In this design, the housing also includes a mounting cavity, which and a liquid storage cavity are distributed along the length of the housing. The mounting cavity provides installation space for the microwave components and the liquid guiding components, preventing them from being exposed to the outside and improving the aesthetics of the aerosol generating device.

[0046] Furthermore, the first sleeve is connected to the mounting cavity, and along the centerline of the first sleeve, one end of the first sleeve is located inside the mounting cavity, and the other end is located outside the mounting cavity, which facilitates the disassembly of the microwave component and the housing, so as to facilitate the maintenance of the aerosol generating device and the replacement of parts.

[0047] In one possible design, the housing further includes an air outlet channel that communicates with the atomizing chamber, and a liquid storage chamber surrounding the air outlet channel.

[0048] In this design, the shell also includes an exhaust channel, which is connected to the atomization chamber. In this way, when the aerosol generating matrix flows to the atomization surface in the atomization chamber under the action of the liquid guide, the aerosol generating matrix is ​​atomized under the action of microwaves. The atomized aerosol flows out through the exhaust channel connected to the atomization chamber for suction.

[0049] The liquid storage chamber is located around the gas outlet channel, which is located in the middle of the shell. Furthermore, the center line of the atomizing chamber coincides with the center line of the shell. In this way, the atomized aerosol in the atomizing chamber can flow directly to the gas outlet channel, thereby shortening the aerosol flow path and improving the mist output and mist output effect of the aerosol generating device.

[0050] In one possible design, the housing further includes a suction nozzle, which is located at both ends of the liquid storage cavity along with the microwave assembly, and the suction nozzle is connected to the air outlet channel.

[0051] In this design, the housing also includes a suction nozzle. The suction nozzle and the microwave component are respectively disposed at both ends of the liquid storage chamber. Furthermore, the suction nozzle is connected to the gas outlet channel. Thus, during suction, the gas enters the housing through the air inlet on the microwave component at one end of the housing and enters the atomization chamber, carrying away the atomized aerosol generation matrix in the atomization chamber. The gas then flows through the gas outlet channel to the suction nozzle for suction. The aerosol generation device provided in this application shortens the gas flow path and increases the amount of mist produced.

Detailed Implementation

[0062] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0063] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0064] The following reference Figures 1 to 6 The aerosol generating apparatus 100 according to some embodiments of the present invention is described.

[0065] like Figure 1 and Figure 2 As shown, according to a first embodiment of the present invention, the present invention provides an aerosol generating device 100, comprising: a housing 102, a liquid guiding component 104, and a microwave component 106.

[0066] Specifically, the housing 102 includes a liquid storage chamber 1020, which contains an aerosol generating matrix. A liquid guiding member 104 is disposed within the housing 102, and includes a liquid guiding section 1040 and an atomizing section 1042 that communicate with each other. An atomizing cavity 1044 is formed inside the atomizing section 1042. The liquid guiding section 1040 communicates with the liquid storage chamber 1020 and is used to transfer the aerosol generating matrix to the atomizing section 1042. The microwave assembly 106 includes a microwave introducing section 1060, at least a portion of which is disposed within the atomizing cavity 1044. The microwave introducing section 1060 is used to feed microwaves into the atomizing cavity 1044 to atomize the aerosol generating matrix.

[0067] The aerosol generating device 100 provided by this invention includes a liquid guiding section 1040 that guides the aerosol generating matrix from the liquid storage chamber 1020 into the atomization chamber 1044. At least a portion of the microwave guiding section 1060 extends into the atomization chamber 1044 to feed microwaves into the microwave chamber 1065. Under the action of microwaves, the aerosol generating matrix absorbs microwave energy, and high-frequency friction occurs between the polar molecules within it, generating heat and thus heating the aerosol generating matrix, achieving atomization for inhalation. In the technical solution proposed in this application, heating the aerosol generating matrix using microwaves ensures that the temperature of each part of the aerosol generating matrix remains consistent, preventing carbonization due to high temperatures. This avoids the burnt taste that can occur with heating the aerosol generating matrix using heating wires or ceramics in related technologies, thus improving the inhalation experience.

[0068] The microwave inlet 1060 extends into the atomization chamber 1044, directly feeding microwaves into it. On one hand, the microwaves atomize the aerosol generation matrix, preventing a burnt taste from affecting the vaping experience. On the other hand, extending the microwave inlet 1060 into the atomization chamber 1044 increases its size, providing more space for the atomized aerosol generation matrix and thus improving the atomization rate. Furthermore, the microwaves fed into the microwave inlet 1060 act directly on the atomization chamber 1044, ensuring effective microwave atomization.

[0069] It is understandable that when microwaves act on the aerosol generating matrix, the aerosol generating matrix absorbs microwave energy, causing high-frequency friction between the polar molecules inside it to generate heat, thereby heating the aerosol generating matrix and causing it to atomize.

[0070] Furthermore, such as Figure 3 As shown, the microwave assembly 106 further includes a conductor 1062, a microwave transmitter, and a power supply. Specifically, the conductor 1062 is connected to the housing 102, a microwave inlet 1060 is disposed within the conductor 1062, and together with the conductor 1062, forms a microwave cavity 1065. At least a portion of the atomizing part 1042 extends into the microwave cavity 1065. The microwave transmitter is connected to the input terminal of the microwave inlet 1060; the power supply is used to supply power to the microwave transmitter.

[0071] In this design, the microwave component 106 also includes a conductor 1062, which is connected to the housing 102. A microwave inlet 1060 is disposed within the conductor 1062, thereby connecting the microwave component 106 to the housing 102. The microwave inlet 1060, located within the conductor 1062, together with the conductor 1062, encloses a microwave cavity 1065. When the microwave inlet 1060 is operating, microwaves can be fed into the microwave cavity 1065, confining the microwaves within the cavity and preventing leakage to the outside of the housing 102, thus preventing microwave loss and improving the energy utilization rate of the microwave component 106. Simultaneously, at least a portion of the atomizing cavity 1044 is disposed within the microwave cavity 1065, enabling the aerosol generating matrix to effectively absorb the microwaves within the microwave cavity 1065, thereby generating heat and atomizing, thus ensuring the atomization effect of the aerosol generating matrix within the microwave cavity 1065. A microwave transmitter is connected to the input terminal of a microwave inlet 1060. The microwave transmitter generates microwaves, which are then conducted through the microwave inlet 1060 into the atomization cavity 1044, thereby atomizing the aerosol matrix within the atomization cavity 1044. A power supply unit is connected to the microwave transmitter to provide power, enabling the microwave transmitter to generate microwaves when powered on.

[0072] In specific applications, the power supply includes a battery, and more specifically, a rechargeable battery.

[0073] It is understood that the conductor 1062 and the microwave assembly 106 form a microwave cavity 1065, wherein the conductor 1062 has the function of shielding microwaves, thereby preventing microwave leakage and improving the safety performance of the aerosol generation matrix.

[0074] Furthermore, the conductor 1062 is in the shape of a hollow cylinder.

[0075] like Figure 1 and Figure 2 As shown, the housing 102 further includes an air outlet channel 1024, which is connected to the atomizing chamber 1044, and a liquid storage chamber 1020 is arranged around the air outlet channel 1024.

[0076] In this design, the housing 102 also includes an exhaust channel 1024, which is connected to the atomization chamber 1044. Thus, when the aerosol generating matrix flows to the atomization surface 1046 in the atomization chamber 1044 under the action of the liquid guiding part 1040, the aerosol generating matrix is ​​atomized under the action of microwaves. The atomized aerosol flows out through the exhaust channel 1024 connected to the atomization chamber 1044 for suction.

[0077] The liquid storage chamber 1020 is arranged around the gas outlet channel 1024, that is, the gas outlet channel 1024 is located in the middle of the housing 102. Furthermore, the center line of the atomizing chamber 1044 coincides with the center line of the housing 102. In this way, the atomized aerosol in the atomizing chamber 1044 can flow directly to the gas outlet channel 1024, thereby shortening the aerosol flow path and improving the mist output and mist output effect of the aerosol generating device 100.

[0078] Furthermore, the housing 102 also includes a mounting cavity. Specifically, at least a portion of the microwave assembly 106 and the liquid guide 104 are disposed within the mounting cavity.

[0079] In this design, the housing 102 also includes a mounting cavity, and the mounting cavity and the liquid storage cavity 1020 are distributed along the length of the housing 102. The mounting cavity provides mounting space for the microwave component 106 and the liquid guide 104, avoiding the microwave component 106 and the liquid guide 104 from being exposed to the outside, thus improving the aesthetics of the aerosol generating device 100.

[0080] like Figure 1 and Figure 2 As shown, the housing 102 further includes a suction nozzle 1022, which and the microwave assembly 106 are located at both ends of the liquid storage cavity 1020. The suction nozzle 1022 is connected to the air outlet channel 1024.

[0081] In this design, the housing 102 also includes a suction nozzle 1022. The suction nozzle 1022 and the microwave component 106 are respectively disposed at both ends of the liquid storage chamber 1020. The suction nozzle 1022 is connected to the gas outlet channel 1024. Thus, during suction, gas enters the housing 102 through the air inlet 1067 on the microwave component 106 at one end of the housing 102 and enters the atomization chamber 1044, carrying away the atomized aerosol generating matrix in the atomization chamber 1044. Then, it flows from the gas outlet channel 1024 to the suction nozzle 1022 for suction. The aerosol generating device 100 provided in this application shortens the gas flow path and increases the amount of mist produced.

[0082] Specifically, the nozzle 1022 includes a metal nozzle 1022. The nozzle 1022 is made of a material capable of shielding microwaves, thereby preventing microwave leakage from the nozzle 1022.

[0083] In specific applications, such as Figure 1 As shown, the oil supply path is as follows: the aerosol generating matrix in the liquid storage chamber 1020 is in direct contact with the liquid guiding component 104, and the liquid guiding component 104 transmits the aerosol generating matrix in the liquid storage chamber 1020 to the atomizing surface 1046 through capillary force.

[0084] like Figure 2 As shown, the airway structure path is as follows: air enters through the air inlet 1067 at the bottom of the housing 102, the liquid on the surface of the atomizing surface 1046 absorbs microwave energy and atomizes, and the atomized aerosol matrix is ​​directly carried out from the air outlet 1024 in the center and then flows out of the suction nozzle 1022 for suction.

[0085] like Figure 5 and Figure 6 As shown, according to the second embodiment of the present invention, based on the first embodiment described above, the atomizing part 1042 further includes an atomizing surface 1046.

[0086] Specifically, the atomizing surface 1046 encloses the atomizing cavity 1044, and the liquid guiding part 1040 is used to deliver the aerosol generation matrix to the atomizing surface 1046.

[0087] In this design, the atomizing section 1042 also includes an atomizing surface 1046, which encloses an atomizing cavity 1044. The liquid guiding section 1040 guides the aerosol generating matrix in the liquid storage cavity 1020 toward the atomizing surface 1046, so that the aerosol generating matrix is ​​distributed on the atomizing surface 1046. Thus, under the action of the microwave fed by the microwave introductory section 1060, the aerosol generating matrix on the atomizing surface 1046 is atomized for suction.

[0088] In practical applications, the atomizing chamber 1044 is a hollow cylinder.

[0089] like Figure 5 and Figure 6 As shown, according to the third embodiment of the present invention, based on the above-described embodiment two, the liquid guiding part 1040 further includes a liquid guiding surface 1048.

[0090] Among them, the liquid guiding surface 1048 can block the outlet of the liquid storage cavity 1020.

[0091] In this design, the liquid guiding section 1040 includes a liquid guiding surface 1048, which blocks the outlet of the liquid storage chamber 1020. This ensures that, on the one hand, the liquid guiding surface 1048 is in complete contact with the aerosol generating matrix in the liquid storage chamber 1020. Under the action of the liquid guiding section 1040, the aerosol generating matrix in the liquid storage chamber 1020 can flow into the atomizing chamber 1044, thereby allowing the aerosol generating matrix on the atomizing surface 1046 to be heated under the action of microwaves and atomized for suction. On the other hand, it also prevents the aerosol generating matrix in the liquid storage chamber 1020 from flowing to other components and affecting the use of the aerosol generating device 100.

[0092] Furthermore, a connector is provided at the outlet of the liquid storage chamber 1020, and a liquid outlet is provided on the connector. The liquid guiding surface 1048 blocks the liquid outlet, so that the liquid guiding surface 1048 can directly contact the aerosol at the liquid outlet to form a matrix. Then, under the action of the liquid guiding part 1040, the aerosol matrix flows to the atomizing chamber 1044.

[0093] According to a fourth embodiment of the present invention, based on the first embodiment described above, the liquid guiding member 104 is made of a porous material, and the liquid guiding part 1040 and the atomizing part 1042 are integrally formed.

[0094] In this design, the liquid guiding component 104 is made of porous material. Porous materials have good adsorption properties, which enables the aerosol generating matrix to be transported to the atomizing part 1042. The liquid guiding part 1040 and the atomizing part 1042 are integrally formed, which improves the connection strength between the liquid guiding part 1040 and the atomizing part 1042, and also ensures that the liquid guiding part 1040 can transport the aerosol generating matrix in the liquid storage chamber 1020 to the atomizing part 1042.

[0095] Furthermore, the liquid guiding component 104 is made of porous ceramic, cotton, or fiber.

[0096] In this design, the liquid guiding component 104 is made of porous ceramic, cotton, or fiber. Porous ceramic, cotton, and fiber all have good adsorption properties. The liquid guiding component 104 is in direct contact with the aerosol matrix in the liquid storage chamber 1020. It can transfer the liquid in the liquid storage chamber 1020 to the atomizing part 1042 through capillary force. Then, the aerosol matrix on the atomizing part 1042 absorbs microwave energy and atomizes for suction.

[0097] According to the fifth embodiment of the present invention, based on the first embodiment described above, the liquid guiding part 1040 and the atomizing part 1042 are independent components. The atomizing part 1042 is a porous material or a substrate with a microporous array through-holes. The liquid guiding part 1040 is provided with a liquid guiding channel to transfer the aerosol generating matrix of the liquid storage chamber 1020 to the atomizing part 1042.

[0098] In this design, the liquid guiding section 1040 and the atomizing section 1042 are independent components, which facilitates the manufacturing and replacement of the liquid guiding section 1040 and the atomizing section 1042. The liquid guiding section 1040 is provided with a liquid guiding channel, which transfers the aerosol generating matrix in the liquid storage chamber 1020 to the atomizing section 1042, where it is atomized under the action of microwaves introduced by the microwave introducing section 1060 for suction.

[0099] The atomizing section 1042 is made of a porous material or a substrate with a microporous array. Porous materials have good adsorption properties, ensuring that the atomizing section 1042 can adsorb a large amount of aerosol generating matrix, thereby increasing the atomization amount of the aerosol generating device 100. A substrate with a microporous array also has good adsorption properties; therefore, setting the atomizing section 1042 to a substrate with a microporous array also allows for the adsorption of a large amount of aerosol generating matrix, thus improving the atomization effect.

[0100] like Figure 3 and Figure 4 As shown, according to the sixth embodiment of the present invention, based on any of the above embodiments, the conductor 1062 further includes: a first sleeve 1064 and a second sleeve 1066.

[0101] Specifically, the first sleeve 1064 is connected to the housing 102, and the first sleeve 1064 is provided with an air inlet 1067, which is connected to the atomizing chamber 1044; the second sleeve 1066 is disposed inside the first sleeve 1064, and the microwave inlet 1060 is disposed inside the second sleeve 1066, forming a microwave cavity 1065 with part of the inner wall surface of the second sleeve 1066.

[0102] In this design, the conductor 1062 includes a first sleeve 1064 and a second sleeve 1066. The first sleeve 1064 is connected to the housing 102, connecting the microwave component 106 to the housing 102. The first sleeve 1064 has an air inlet 1067, through which air enters the atomization chamber 1044, carrying the atomized aerosol generating matrix out of the housing 102 for suction. The second sleeve 1066 is disposed within the first sleeve 1064. The second sleeve 1066 and the microwave inlet 1060 together enclose a microwave cavity 1065, shielding the microwaves, preventing microwave leakage, and improving the safety performance of the aerosol generating matrix. At least a portion of the atomization chamber 1044 is disposed within the microwave cavity 1065, ensuring effective atomization of the aerosol generating matrix within the atomization chamber 1044, thereby improving the suction experience.

[0103] like Figure 4 As shown, according to the seventh embodiment of the present invention, based on the above-described sixth embodiment, the microwave introductory part 1060 and the second sleeve 1066 are further arranged coaxially.

[0104] In this design, the microwave inlet 1060 and the second sleeve 1066 are coaxially arranged, which avoids uneven heating of the aerosol generating matrix caused by the concentration of microwaves in the microwave cavity 1065. This ensures that the microwave energy is uniform at all positions in the microwave cavity 1065, thereby ensuring that the aerosol generating matrix at all points on the atomizing surface 1046 can absorb microwave energy and atomize, further improving the atomization effect of the aerosol generating matrix.

[0105] It is understandable that the microwave inlet 1060 is cylindrical, and the second sleeve 1066 is also a hollow cylinder.

[0106] Furthermore, the atomizing cavity 1044, the microwave inlet 1060, and the second sleeve 1066 are all coaxially arranged.

[0107] Furthermore, the second sleeve 1066 includes a first cavity 1068 and a second cavity 1069.

[0108] Specifically, the inner wall of the first cavity 1068 and the microwave inlet 1060 form a microwave cavity 1065; the first cavity 1068 is connected to the second cavity 1069, the second cavity 1069 is located on the side of the first cavity 1068 away from the liquid guide 104, the second cavity 1069 is provided with an insulating member 1063, and the microwave inlet 1060 passes through the insulating member 1063.

[0109] In this design, the second sleeve 1066 includes a first cavity 1068 and a second cavity 1069. The inner wall of the first cavity 1068 and the microwave inlet 1060 enclose a microwave cavity 1065, thereby enabling microwave energy to be present in the microwave cavity 1065. An insulating member 1063 is provided in the second cavity 1069 to achieve an insulating connection between the microwave inlet 1060 and the second sleeve 1066, thereby reducing microwave loss.

[0110] It is understood that the first cavity 1068 and the second cavity 1069 are distributed along the axial direction of the second sleeve 1066. The second cavity 1069 is located on the side of the first cavity 1068 away from the liquid guiding member 104.

[0111] In specific applications, the insulating component 1063 is made of a material that can withstand high temperatures of 400°C. Specifically, the insulating component 1063 is a hollow column, and the microwave inlet 1060 is inserted into the hollow of the insulating component 1063, so that the inner sidewall of the insulating component 1063 covers the outer sidewall of the microwave inlet 1060, thereby improving the connection reliability between the insulating component 1063 and the microwave inlet 1060.

[0112] Furthermore, when the diameter of the microwave inlet 1060 is 1.5 mm, the outer diameter of the insulating member 1063 is greater than 5.2 mm. This arrangement can result in a lower microwave loss rate.

[0113] Furthermore, the first sleeve 1064 and the second sleeve 1066 are metal parts.

[0114] In this design, the first sleeve 1064 and the second sleeve 1066 are metal parts, which can both provide power and shield microwaves to prevent microwave leakage.

[0115] Furthermore, both the first sleeve 1064 and the second sleeve 1066 are metal parts, which enables both the first sleeve 1064 and the second sleeve 1066 to avoid microwave leakage, thereby improving the safety of the aerosol generating device 100.

[0116] In specific applications, the housing 102 is made of metal, or the inner wall of the housing 102 is provided with a metal layer, thereby enabling the housing 102 to shield microwaves and further prevent microwave leakage.

[0117] Furthermore, the power supply component is connected to the second sleeve 1066, specifically, the power supply component is detachably connected to the second sleeve 1066.

[0118] Furthermore, the first sleeve 1064 is connected to the mounting cavity, and along the center line direction of the first sleeve 1064, one end of the first sleeve 1064 is disposed inside the mounting cavity, and the other end is located outside the mounting cavity, thereby facilitating the disassembly of the microwave assembly 106 and the housing 102, so as to facilitate the maintenance of the aerosol generating device 100 and the replacement of parts.
