Technical Field

[0003] The present application relates to the field of atomization technology, and in particular to an aerosol generating device. Background Art

[0004] An aerosol is a colloidal dispersion system composed of small solid or liquid particles dispersed and suspended in a gaseous medium. Because aerosols can be absorbed through the respiratory system, they offer users a novel alternative absorption method. An aerosol-generating device is a device that converts a stored atomizable medium into an aerosol through heating or ultrasound. Atomizable media include liquids, gels, pastes, or solid aerosol-generating matrices. Atomizing these media delivers an inhalable aerosol to the user, replacing conventional product forms and absorption methods.

[0005] Microwave heating is a heating technology that uses microwave radiation to atomize a medium, causing the atomized medium to generate heat and temperature through its own dielectric loss to produce aerosol. It has the characteristics of immediacy, integrity, and selectivity. Since microwave heating utilizes the heated substance to absorb microwaves itself and generates heat through internal molecular loss, no separate heating element is required.

[0006] However, in some cases, in an aerosol generating device that utilizes microwave heating, the higher-temperature aerosol generated by the atomization of the aerosol generating matrix contacts the lower-temperature aerosol generating device, and condensation will occur to form condensation deposited in the resonant cavity. A large amount of condensation deposition will cause energy loss, resulting in insufficient heating of the aerosol generating matrix, thereby affecting the amount of aerosol generated and the taste, and reducing the user experience.

[0048] 1 , an aerosol generating device 100 is provided in one embodiment of the present application. An aerosol generating substrate 200 can be inserted into one end of the aerosol generating device 100 . The aerosol generating device 100 can generate microwaves to atomize the aerosol generating substrate 200 to generate an aerosol for a user to take.

[0049] In some embodiments, the aerosol-generating substrate 200 includes a substrate body and a coating layer coated on the outside of the substrate body. The substrate body can be a solid in the form of crushed, granulated, powdered, granular, strip or sheet. The coating layer is formed by a coating material. The coating layer is coated on the outside of the substrate body to keep the aerosol-generating substrate 200 in a certain shape.

[0050] As shown in FIG. 1 to FIG. 4 , the aerosol generating device 100 includes an outer conductor 110 , an inner conductor 120 , an upper cover 140 , a microwave feeding unit 150 , and a pusher 160 .

[0051] The outer conductor 110 has a hollow cylindrical structure and includes an outer conductor bottom wall 112, an outer conductor side wall 114, and an outer conductor top wall 116. The outer conductor side wall 114 extends in the same direction from the edge of the outer conductor bottom wall 112 and circumferentially surrounds the outer conductor bottom wall 112. The outer conductor top wall 116 is located on the side of the outer conductor side wall 114 away from the outer conductor bottom wall 112. Together, the outer conductor bottom wall 112, the outer conductor side wall 114, and the outer conductor top wall 116 form a cavity. The outer conductor bottom wall 112 forms the bottom end of the outer conductor 110, while the outer conductor top wall 116 defines a communication port 116a, forming the open end of the outer conductor 110. The bottom end and the open end are disposed opposite each other in the axial direction of the outer conductor 110, and the communication port 116a communicates with the cavity.

[0052] Furthermore, a first mounting hole 112a is defined at the center of the outer conductor bottom wall 112. The first mounting hole 112a extends through the outer conductor bottom wall 112 along its thickness, allowing the pusher 160 to pass through and also securing the inner conductor 120. A second mounting hole 112b is defined at an edge of the outer conductor bottom wall 112. The second mounting hole 112b extends through the outer conductor bottom wall 112 along its thickness, allowing for mounting the microwave feeding unit 150.

[0053] The inner conductor 120 has a hollow cylindrical structure. A receiving cavity 120a is formed in the inner conductor 120. The outer diameter of the inner conductor 120 is smaller than the inner diameter of the outer conductor 110. The inner conductor 120 is housed in the outer conductor 110 and is coaxially arranged with the outer conductor 110. One end of the inner conductor 120 is matched with and electrically connected to the bottom end of the outer conductor 110. The other end of the inner conductor 120 extends toward the open end of the outer conductor 110 and is spaced apart from the open end. The end face of the inner conductor 120 facing the open end of the outer conductor 110 is annular.

[0054] Specifically, the inner conductor 120 includes an inner conductor body 121 and an inner conductor mounting portion 123 connected to one axial end of the inner conductor body 121. The outer diameter of the inner conductor mounting portion 123 is smaller than that of the inner conductor body 121. The inner conductor mounting portion 123 is inserted into a first mounting hole 112a in the outer conductor bottom wall 112 and is threadedly connected to the outer conductor 110. One end of the inner conductor body 121 connected to the inner conductor mounting portion 123 abuts against the outer conductor bottom wall 112, while the other end extends toward the open end of the outer conductor 110. Thus, a resonant cavity 130 is defined between the outer conductor 110 and the inner conductor 120, and the resonant cavity 130 circumferentially surrounds the inner conductor body 121.

[0055] The upper cover 140 has a hollow, rotating structure. One end of the upper cover 140 is coupled to the open end of the outer conductor 110 and is coaxially arranged with the outer conductor 110. A plug-in channel 141 is formed within the upper cover 140 and communicates with the communication port 116a. The inner diameter of the plug-in channel 141 is the same as that of the communication port 116a. One end of the aerosol-generating substrate 200 can pass through the plug-in channel 141 and the communication port 116a and extend into the inner conductor 120. The plug-in channel 141, the communication port 116a, and the inner conductor 120 can be coaxially arranged.

[0056] In some embodiments, the upper cover 140 is integrally formed with the outer conductor top wall 116 of the outer conductor 110 . The outer conductor top wall 116 is threadedly connected to the outer conductor side wall 114 or pressed against the top surface of the outer conductor side wall 114 .

[0057] The microwave feed unit 150 can be a coaxial connector. One end of the microwave feed unit 150 extends through the second mounting hole 112b in the outer conductor bottom wall 112 and into the resonant cavity 130. The other end of the microwave feed unit 150 extends beyond the outer conductor bottom wall 112 to connect to an external microwave source. The energy generated by the microwave source is fed into the resonant cavity 130 through the microwave feed unit 150, and then atomizes the aerosol-generating substrate 200 between the open end of the outer conductor 110 and the inner conductor 120.

[0058] One end of the pushing member 160 extends into the inner conductor 120 along the axial direction of the inner conductor 120 and can move in the axial direction within the inner conductor 120, thereby pushing the aerosol generating substrate 200 to move along the axial direction of the inner conductor 120. Different parts of the aerosol generating substrate 200 sequentially enter the area between the inner conductor 120 and the open end of the outer conductor 110 to be atomized by microwaves.

[0059] As described in the background, microwaves fed into the resonant cavity 130 heat the aerosol-generating substrate 200 through its own dielectric loss. Therefore, the temperature of the outer conductor top wall 116 and the upper cover 140 is lower than that of the aerosol. As the aerosol passes through the outer conductor top wall 116 and the upper cover 140, the high-temperature aerosol cools and condenses, gathering on the end surface of the outer conductor top wall 116 facing the inner conductor 120. This affects the resonant frequency and the dielectric constant within the resonant cavity 130, thereby affecting the heating of the aerosol-generating substrate 200.

[0060] Please continue to refer to Figures 1 to 4. Based on the above technical problems, an atomization area for atomizing the aerosol generating matrix 200 is formed between the top surface of the inner conductor 120 and the open end of the outer conductor 110. The aerosol generating device 100 also includes a condensation sealing tube 170. The condensation sealing tube 170 closes the atomization area and forms an atomization channel 170a inside the condensation sealing tube 170. The condensation sealing tube 170 connects the inner conductor 120 and the connecting port 116a. Microwaves can pass through the tube wall of the condensation sealing tube 170 and enter the atomization channel 170a.

[0061] Since the connecting port 116a at the open end of the outer conductor 110 and the inner conductor 120 are connected through the condensation sealing tube 170, the flow path of the aerosol can be restricted, and the condensation and deposition of the aerosol in the gap between the inner conductor 120 and the outer conductor 110 can be reduced, thereby effectively alleviating the energy loss and insufficient heating caused by the generation of condensation, thereby improving the amount of aerosol generated and the taste.

[0062] Specifically, at least a portion of the tube wall of the condensation sealing tube 170 forming the atomization channel 170a includes or is formed of a wave-transparent material. Therefore, the microwaves fed into the resonant cavity 130 can pass through the tube wall of the condensation sealing tube 170 and enter the atomization channel 170a to heat the aerosol-generating substrate 200. It will be understood that the material forming the condensation sealing tube 170 is not limited, but the condensation sealing tube 170 located in the atomization area is formed of a wave-transparent material. In some embodiments, the condensation sealing tube 170 is entirely formed of a wave-transparent material such as fiberglass, ceramic, or polyimide.

[0063] As shown in Figure 4, in one embodiment of the present application, the condensation sealing tube 170 is a hollow circular tubular structure formed by a wave-transparent material. The outer diameter of the condensation sealing tube 170 matches the inner diameter of the inner conductor 120. One end of the condensation sealing tube 170 is inserted into the inner conductor body 121 and abuts against one end of the inner conductor body 121 connected to the inner conductor mounting portion 123. The other end of the condensation sealing tube 170 extends out of the inner conductor body 121 away from the inner conductor mounting portion 123 and abuts against the open end of the outer conductor 110 facing the end face of the inner conductor 120. The interior of the end of the condensation sealing tube 170 extending out of the inner conductor 120 is constructed to form an atomization channel 170a, and the inner diameter of the atomization channel 170a is roughly the same as the inner diameter of the connecting port 116a.

[0064] As shown in Figure 5, in another embodiment of the present application, the condensation sealing tube 170 is a circular structure formed by a wave-transparent material. The height of the condensation sealing tube 170 matches the gap value between the open ends of the inner conductor 120 and the outer conductor 110. The condensation sealing tube 170 is supported between the open ends of the inner conductor 120 and the outer conductor 110, and the interior of the condensation sealing tube 170 is constructed to form an atomization channel 170a.

[0065] Furthermore, as shown in FIG5 , the aerosol generating device 100 also includes a first annular sealing ring 181 and a second annular sealing ring 183 . The first sealing ring 181 is positioned between the condensation sealing tube 170 and the inner conductor 120 , while the second sealing ring 183 is positioned between the condensation sealing tube 170 and the open end of the outer conductor 110 . The first sealing ring 181 and the second sealing ring 183 are formed from elastically deformable materials such as rubber, thereby sealing the gaps between the condensation sealing tube 170 and the open ends of the inner conductor 120 and the outer conductor 110 , further preventing the aerosol from diffusing outward. As a preferred embodiment, the condensation sealing tube 170 has two annular retaining grooves at opposite ends in the axial direction, and the first sealing ring 181 and the second sealing ring 183 can be respectively embedded in the two retaining grooves.

[0066] In the above embodiment, since the length of the condensation sealing tube 170 is relatively short, the energy loss can be effectively reduced and the atomization efficiency can be improved.

[0067] As shown in Figure 6, in another embodiment of the present application, the condensation sealing tube 170 is a hollow cylindrical structure formed of a wave-transparent material. The outer diameter of the condensation sealing tube 170 matches the inner diameter of the inner conductor 120. One end of the condensation sealing tube 170 is inserted into the inner conductor body 121 and abuts against one end of the inner conductor body 121 connected to the inner conductor mounting portion 123. The other end of the condensation sealing tube 170 passes through the connecting port 116a and extends into the plug-in channel 141 of the upper cover 140. The interior of the part of the condensation sealing tube 170 located between the inner conductor 120 and the upper cover 140 is constructed to form an atomization channel 170a.

[0068] It can be understood that the length of the condensation sealing tube 170 extending into the plug-in channel 141 of the upper cover 140 is not limited. In one embodiment, the condensation sealing tube 170 may only extend into one end of the plug-in channel 141 facing the inner conductor 120. In another embodiment, one end of the condensation sealing tube 170 extends to the end of the plug-in channel 141 away from the inner conductor 120.

[0069] Please refer to Figures 6 and 7. In some embodiments, the aerosol generating device 100 further includes a non-conductive connecting portion 192, which is used to connect the inner conductor 120 and the upper cover 140. A wave-transparent portion 194 is constructed between the inner conductor 120 and the upper cover 140. The microwaves in the resonant cavity 130 can pass through the wave-transparent portion 194 and enter the accommodating cavity 120a.

[0070] In this way, when the remaining aerosol-generating substrate 200 needs to be removed after use, the inner conductor 120 and the upper cover 140 can be simultaneously withdrawn from the outer conductor 110, and the aerosol-generating substrate 200 can then be separated, thereby preventing residue of the aerosol-generating substrate 200 from remaining in the resonant cavity 130. Furthermore, since a wave-transmitting portion 194 is provided between the inner conductor 120 and the upper cover 140 to allow microwaves to pass through, the atomization of the aerosol-generating substrate 200 is not affected.

[0071] Specifically, in the following embodiments, the upper cover 140 and the outer conductor 110 are both metal components. The upper cover 140 and the outer conductor top wall 116 are integrally formed. The connecting portion 192 connects the inner conductor 120 and the outer conductor top wall 116. Therefore, the connecting portion 192 is indirectly connected to the upper cover 140 via the outer conductor top wall 116. In other embodiments, the inner conductor 120 and the upper cover 140 are directly connected via the connecting portion 192.

[0072] Continuing with Figures 7 and 8 , in some embodiments, the space between the inner conductor 120 and the outer conductor top wall 116 where the connection portion 192 is not provided forms at least one communication slot 196. The communication slots 196 are arranged circumferentially around the accommodating cavity 120a. The communication slots 196 form the wave-transmitting portion 194, allowing microwaves in the resonant cavity 130 to enter the accommodating cavity 120a through the communication slots 196. It will be appreciated that the shape, number, and placement of the connection portion 192 are not limited, and accordingly, the shape, number, and placement of the communication slots 196 are not limited.

[0073] More specifically, in one embodiment, two connecting portions 192 are provided between the inner conductor 120 and the outer conductor top wall 116 and are spaced apart along the circumference of the accommodating cavity 120a. Two communicating grooves 196 of the same shape are formed between the two connecting portions 192. The two communicating grooves 196 are spaced apart along the circumference of the accommodating cavity 120a, and each communicating groove 196 extends along the circumference of the accommodating cavity 120a and is in the shape of an arc.

[0074] 7 and 9 , in another embodiment, the aerosol generating device 100 further includes a wave-transparent member 198 , which is embedded in the connecting groove 196 and formed of a wave-transparent material. Microwaves in the resonant cavity 130 can pass through the wave-transparent member 198 and enter the accommodating cavity 120 a.

[0075] It is understood that the shape, number, and location of the communication slots 196 are not limited, and the shape and number of the wave-transparent members 198 match the shape and number of the communication slots 196. Specifically, in one embodiment, two identically shaped communication slots 196 are provided between the inner conductor 120 and the upper cover 140. Both communication slots 196 are located near the open end of the outer conductor 110. The two communication slots 196 are spaced apart along the circumference of the inner conductor 120, and each communication slot 196 extends along the circumference of the accommodating cavity 120a and has an arc shape. Two wave-transparent members 198 are respectively embedded in one of the communication slots 196, and each wave-transparent member 198 has an arc shape.

[0076] The wave-transparent member 198 is set to allow microwaves to enter the accommodating cavity 120a while limiting the flow path of the aerosol, effectively preventing the condensation and deposition of the aerosol at the connecting groove 196 to form condensation, thereby alleviating the energy loss and insufficient heating caused by the generation of condensation, and thereby improving the amount of aerosol generated and the taste.

[0077] As shown in Figures 10, 11 and 12, in some embodiments, the connecting portion 192 includes a first clip 1921 and a second clip 1923, one of the inner conductor 120 and the outer conductor top wall 116 is provided with at least one first clip 1921, and the other of the inner conductor 120 and the outer conductor top wall 116 is provided with at least one second clip 1923, and each second clip 1923 is clamped on a first clip 1921 to form a complete connecting portion 192.

[0078] Specifically, in one embodiment, two second clips 1923 are protruding from one end of the inner conductor body 121 facing the outer conductor top wall 116. The two second clips 1923 are spaced apart circumferentially around the inner conductor body 121, and two first clips 1921 are formed between the two second clips 1923. Two first clips 1921 are also provided on the side of the outer conductor top wall 116 facing the inner conductor 120. The two first clips 1921 are spaced apart circumferentially around the outer conductor top wall 116 so as to mate with the second clips 1923. It will be appreciated that the number of second clips 1923 and first clips 1921 is not limited to this and can be provided as needed to meet the mating requirements between the inner conductor 120 and the outer conductor top wall 116.

[0079] The aerosol generating device 100, by disposing a condensation sealing tube 170 within the outer conductor 110 to form an atomization channel 170a connecting the open ends of the inner conductor 120 and the outer conductor 110, effectively prevents aerosol from condensing between the open ends of the inner conductor 120 and the outer conductor 110 to form condensation. This reduces energy consumption within the aerosol generating device 100, ensures more efficient heating of the aerosol generating substrate 200, increases aerosol production, and enhances the puffing experience. Furthermore, because the upper cover 140 and the inner conductor 120 can be removed from the outer conductor 110 as a single unit, residue of the aerosol generating substrate 200 is prevented from remaining in the resonant cavity 130, and the aerosol generating device 100 can be easily cleaned.
