Description

Technical Field

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

[0002] Aerosol generating devices are small electronic devices that generate aerosols by heating an atomizing medium using a non-combustible method. Currently, atomizing media are available in two main forms: solid and liquid. Due to their different heating and atomization characteristics, liquid atomizing media typically require dedicated atomizing components, resulting in a larger overall size and incompatibility with heat-not-burning appliances. This makes it difficult for heat-not-burning appliances to be compatible with both solid and liquid atomizing media. Therefore, developing an atomizing component that can accommodate liquid atomizing media and is compatible with heat-not-burning appliances has become a key technical problem to be solved. Utility Model Content

[0003] This application provides an atomizing component and an aerosol generating device, and is at least used to provide an atomizing component adapted to a heated non-combustible appliance.

[0004] The atomizing assembly of this application embodiment is detachably inserted into the housing of an aerosol generating device. It includes an atomizing tube, a heating element, a conductive terminal, and a filter nozzle. The atomizing tube forms a receiving space containing a liquid atomizing medium. The heating element is housed within the atomizing tube. The conductive terminal is electrically connected to the heating element and is located at the first end of the atomizing tube's axial direction. The conductive terminal is used to make contact with the contacts of the aerosol generating device when the atomizing assembly is inserted into the housing. The filter nozzle is located at the second end of the atomizing tube's axial direction. The atomizing assembly is cylindrical in shape, with an outer diameter ranging from 5 mm to 8 mm and a length ranging from 40 mm to 80 mm.

[0005] In the atomizing component of this application, an atomizing tube is sleeved outside the heating body, forming a accommodating space to hold the liquid atomizing medium. The atomizing component is cylindrical in shape, with its outer diameter and length set within a reasonable range, which facilitates miniaturization. Furthermore, the shape and size of the atomizing component are similar to those of the solid atomizing medium, making it compatible with aerosol generating devices of the same specifications. In addition, the heating element is housed inside the atomizing tube and electrically connected to a conductive terminal, so that the starting and stopping of the heating element is controlled by whether the conductive terminal is energized. Thus, the conductive terminal can activate the heating element to heat the atomizing component after it is installed in the aerosol generating device, and the user can then inhale through the filter nozzle. This improves the ease of use of the atomizing component, enhances its compatibility with aerosol generating devices, and increases the feasibility of using the atomizing component with solid atomizing media.

[0006] In some embodiments, the atomizing component includes a vent tube that is fitted inside the atomizing tube, and the outer wall of the vent tube and the inner wall of the atomizing tube together define an accommodating space.

[0007] In this way, the vent tube and the inner wall of the atomizing tube together define the accommodating space, thereby isolating the storage space of the liquid atomizing medium and the flow path of the airflow carrying the aerosol. This is beneficial to improving the purity of the liquid atomizing medium and the aerosol formed after atomization, and also effectively utilizes the internal space of the atomizing tube, which is conducive to a compact structure.

[0008] In some embodiments, the heating element is disposed inside the vent pipe, and the vent pipe wall is provided with an oil guide hole, which is used to guide the liquid atomizing medium to flow from the self-contained space to the heating element.

[0009] In this way, by placing the heating element in the vent pipe, and providing oil guide holes on the pipe wall, the liquid atomizing medium can flow from the accommodating space to the heating element through the oil guide holes and be heated in the vent pipe. This isolates the heating and storage space of the liquid atomizing medium, improving the purity of the liquid atomizing medium. Furthermore, the diameter of the oil guide holes can also limit the flow rate of the liquid atomizing medium into the vent pipe to match the heating area of ​​the heating element, thus facilitating sufficient heating.

[0010] In some embodiments, the atomizing component includes an oil guide that is wrapped around the heating body and covers the oil guide hole, and the oil guide is used to adsorb liquid atomizing medium.

[0011] In this way, by wrapping the oil guide component around the heating body and covering the oil guide hole, the oil guide component can adsorb the liquid atomizing medium from the containment space into the atomizing tube, and fix a small amount of liquid atomizing medium around the heating body for heating.

[0012] In some embodiments, the filter tip has a first vent hole communicating with the vent tube, the atomizing assembly includes a mounting member disposed at the second end of the atomizing tube in the axial direction and used to seal the accommodating space, the mounting member has a second vent hole opposite to and communicating with the vent tube, the filter tip is stacked on the mounting member and the first vent hole communicates with the second vent hole.

[0013] Thus, a first vent hole is formed by the filter tip and connected to the vent tube, the mounting piece seals the receiving space at the second end, and the mounting piece forms a second vent hole that is opposite to and connected to the vent tube. The filter tip is stacked on the mounting piece and the first vent hole is connected to the second vent hole, thereby allowing the user to draw in the aerosol that escapes along the vent tube through the filter tip and reducing the risk of leakage of liquid atomized medium.

[0014] In some embodiments, the mounting member has an oil filling hole communicating with the accommodating space, and the atomizing assembly includes a seal detachably connected to the mounting member for sealing the oil filling hole.

[0015] In this way, by sealing the oil injection hole with a seal that is detachably connected to the mounting component, liquid atomizing medium can be injected into the accommodating space through the oil injection hole during the assembly of the atomizing component, and the oil injection hole is sealed after the liquid injection is completed. This improves the feasibility and convenience of manufacturing while maintaining the airtightness of the accommodating space.

[0016] In some embodiments, the atomizing assembly includes a base disposed at a first end, with conductive terminals embedded in the base and at least partially exposed outside the base.

[0017] Thus, by embedding conductive terminals on the base and exposing at least part of them outside the base, the conductive terminals are stably connected to the atomizing tube, and the conductive terminals can be connected to the contacts on the aerosol generating device through the exposed part, thereby enabling the heating element to establish a connection with the aerosol generating device when the atomizing component is installed in the aerosol generating device.

[0018] In some embodiments, the atomizing component includes a vent tube that communicates with the external environment and is fitted inside the atomizing tube. The outer wall of the vent tube and the inner wall of the atomizing tube together define an accommodating space, and the base has a third vent hole that communicates with the vent tube.

[0019] Thus, a third vent is formed by the base and connected to the vent tube. The outer wall of the vent tube and the inner wall of the atomizing tube together define the accommodating space, allowing air from the outside environment to enter the atomizing component from the first end of the atomizing tube and mix with the aerosol. Then, the airflow carrying the aerosol can flow upward until it is inhaled by the user through the filter.

[0020] In some embodiments, the atomizing component includes an oil reservoir, in which a liquid atomizing medium is stored, and the oil reservoir is housed within an accommodating space.

[0021] In this way, the risk of leakage is reduced by adsorbing the liquid atomizing medium through the oil storage component and storing the oil storage component in the containment space.

[0022] The aerosol generating apparatus of this application includes a housing and contacts, wherein:

[0023] The housing has a receiving cavity for accommodating the atomizing component of any of the above embodiments;

[0024] Contacts are provided on the housing and are used to connect with the conductive terminals of the atomizing component when the atomizing component is installed in the receiving cavity, so that the heating element of the atomizing component can start heating.

[0025] The aerosol generating device of this application is used in conjunction with an atomizing component to generate aerosols. A heating element is housed within an atomizing tube and electrically connected to conductive terminals. These conductive terminals can be connected to contacts after the atomizing component is inserted into the aerosol generating device, allowing the aerosol generating device to control the heating and atomization process of the atomizing component. After the atomizing component is inserted into the receiving cavity and the heating element begins heating, the user can inhale through the filter nozzle, improving the ease of use of the atomizing component.

[0044] The atomizing medium is a plant flower, stem, or leaf product that has been treated and heated to produce aerosols. The atomizing medium can be in a fully solid, semi-solid, or liquid state.

[0045] When heated, the atomizing medium atomizes to form an aerosol. The aerosol can be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. Users can inhale the aerosol into their mouth, nasal cavity, or lungs through their mouth or nose. Aerosols inhaled into the user's respiratory system can be used for various purposes, including food, medicine, health care, and recreation.

[0046] Please see Figure 1 and Figure 7 The atomizing component 100 of this application embodiment is used to carry the liquid atomizing medium 300 and is detachably inserted into the housing 210 of the aerosol generating device 200, thereby causing the liquid atomizing medium 300 to be atomized in the aerosol generating device 200 to generate aerosol.

[0047] Please see Figures 2-4 The atomizing assembly 100 of this application includes an atomizing tube 10, a heating element 20, a conductive terminal 30, and a filter nozzle 40. The atomizing tube 10 forms a receiving space 101, which contains a liquid atomizing medium 300. The heating element 20 is housed within the atomizing tube 10. The conductive terminal 30 is electrically connected to the heating element 20 and is located at the first end 11 in the axial direction of the atomizing tube 10. The conductive terminal 30 is used to make contact with the contact 220 of the aerosol generating device 200 when the atomizing assembly 100 is inserted into the housing 210. The filter nozzle 40 is disposed at the second end 12 in the axial direction of the atomizing tube 10. The atomizing assembly 100 is cylindrical in shape, with an outer diameter ranging from 5 mm to 8 mm (including the end point) and a length ranging from 40 mm to 80 mm (including the end point).

[0048] In the atomizing component 100 of this embodiment, an atomizing tube 10 is sleeved outside the heating element 20 and forms a receiving space 101 to accommodate the liquid atomizing medium 300. The atomizing component 100 is cylindrical in shape, and its outer diameter and length are set within a reasonable range, which facilitates the detachable insertion of the atomizing component 100 into the housing of the aerosol generating device 200. This is beneficial for the miniaturization of the atomizing component 100, and the shape and size of the atomizing component 100 are relatively close to those of the solid atomizing medium, so it can be adapted to aerosol generating devices 200 of the same specifications. The inner wall of the atomizing tube 10 forms a receiving space 101 for accommodating the liquid atomizing medium 300. The size of the receiving space 101 is reasonably determined according to the outer diameter and length of the atomizing tube 10 to ensure that enough liquid atomizing medium 300 can be stored to meet the user's needs.

[0049] Furthermore, the heating element 20 is housed within the atomizing tube 10 and electrically connected to the conductive terminal 30, so that the start-up and stop of the heating element 20 are controlled by whether the conductive terminal 30 is energized. Thus, the conductive terminal 30 can start the heating element 20 for heating after the atomizing assembly 100 is installed in the aerosol generating device 200, and the user can then inhale through the filter 40. This improves the ease of use of the atomizing assembly 100, enhances the universality of matching the aerosol generating device 200, and increases the feasibility of using the atomizing assembly 100 with solid atomizing media.

[0050] Specifically, for ease of explanation, this application defines the axial direction of the atomizing tube 10 as the vertical direction, and the direction along the axial direction of the atomizing tube 10 from the first end 11 to the second end 12 as the upward direction. Both the first end 11 and the second end 12 of the atomizing tube 10 can be open to allow other components such as the heating element 20 and the liquid atomizing medium 300 to be inserted into the atomizing tube 10. The cross-sectional outer contour shape of the atomizing tube 10 can be circular, elliptical, triangular, quadrilateral, polygonal, or other shapes; this application does not impose any limitations on this. The dimensions of the atomizing tube 10 along the axial direction can be equal or unequal.

[0051] The heating element 20 can be a component or assembly that generates heat using one or more heating principles such as resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, or mechanical vibration. For example, the heating element 20 heats based on the principle of resistance heating, converting electrical energy into resistance heat when connected to electricity, thereby heating the liquid atomizing medium 300. The heating element 20 can be a heating wire, heating mesh, solenoid, or other structures. For example, the heating element 20 is a ceramic heating element, which features uniform heating and high thermal efficiency, enabling rapid conversion of the liquid atomizing medium 300 into an aerosol.

[0052] The installation position of the heating element 20 needs to take into account the contact effect with the liquid atomizing medium 300 and the heat transfer efficiency. Generally, the heating element 20 is placed close to the oil guiding structure so that the liquid atomizing medium 300 can quickly reach the surface of the heating element 20 for atomization.

[0053] The conductive terminal 30 can be electrically connected to the heating element 20 via a conductive component such as a lead 21, or it can be directly connected to the heating element 20. When the atomizing assembly 100 is installed on the aerosol generating device 200, the conductive terminal 30 establishes an electrical connection with the aerosol generating device 200, allowing the heating element 20 to also connect to the power supply circuit 230 and control components 240 of the aerosol generating device 200. This enables the user to operate the aerosol generating device 200 to control the heating and atomization process when the atomizing assembly 100 is installed, and facilitates the replacement of different atomizing assemblies 100 for vaping, improving both operation and the vaping experience. The conductive terminal 30 is typically made of metallic materials such as copper or nickel, possessing good conductivity and corrosion resistance. The electrical connection between the conductive terminal 30 and the heating element 20 can be achieved through welding, plug-in connection, or threaded connection. Welding ensures a strong and conductive connection; plug-in connection facilitates installation and disassembly; threaded connection combines the advantages of both, ensuring a good electrical connection through the tightening effect of the threads.

[0054] During inhalation, the user can insert the filter tip 40 directly into the nasal cavity or mouth for inhalation. The filter tip 40 is located at the second end 12 of the atomizing tube 10 along its axial direction, and its function is to filter the atomized aerosol, improving the quality of the aerosol inhaled by the user. The filter tip 40 is typically made of porous materials, such as activated carbon fiber or polylactic acid (PLA). Activated carbon fiber adsorbs odors and harmful substances, effectively removing impurities from the aerosol; polylactic acid is a biodegradable material with good permeability and filtration performance. The structural design of the filter tip 40 can be optimized as needed, for example, by setting a multi-layer filtration structure with different pore sizes to effectively filter particles of different sizes. Simultaneously, the shape and size of the filter tip 40 must match the atomizing tube 10 to ensure good sealing and user experience. The cross-sectional shape and size of the filter tip 40 correspond to and match the cross-sectional shape and size of the atomizing tube 10. For example, the atomizing tube 10 is a round tube, which facilitates the detachable plug-in connection between the atomizing component 100 and the housing 210 of the aerosol generating device 200. Correspondingly, the filter nozzle 40 has an overall short cylindrical structure.

[0055] Optionally, the filter tip 40 is located on top of the atomizing assembly 100. The filter tip 40 may be made of a porous material and can filter aerosols.

[0056] Optionally, the atomizing assembly 100 further includes a housing 90, which may be a tubular structure enclosing the atomizing tube 10 and the filter nozzle 40. The outer tube provides a certain degree of restraint and support. In this embodiment, the projection of the filter nozzle 40 along the axial direction onto the cross-section of the atomizing tube 10 coincides with the cross-section of the atomizing tube 10, and the outer peripheral surfaces of both the filter nozzle 40 and the atomizing tube 10 are in close contact with the inner wall surface of the outer tube. The housing 90 may be made of paper material.

[0057] Optionally, the outer diameter of the atomizing component 100 ranges from 5 mm to 8 mm (including the endpoints). For example, the outer diameter of the atomizing component 100 is 5 mm, 5.4 mm, 6 mm, 6.5 mm, 6.8 mm, 7.2 mm, 7.6 mm, or 8 mm.

[0058] Optionally, the length of the atomizing component 100 can range from 40mm to 80mm (including the end points). For example, the length range of the atomizing component 100 is 40mm, 45mm, 48mm, 50mm, 52mm, 54mm, 58mm, 60mm, 63mm, 65mm, 72mm, and 80mm.

[0059] Optionally, the atomizing component 100 is generally in the shape of a relatively slender cylinder. The ratio of the diameter to the length of the atomizing component 100 can be 3 / 25, 1 / 8, 2 / 15, 3 / 20, 1 / 10, etc.

[0060] Optionally, the atomizing tube 10 has a cylindrical structure, and the length of the atomizing tube 10 can range from 30mm to 70mm (including the end point). The filter tip 40 has a short cylindrical structure with a diameter matching that of the atomizing tube 10, and the length of the filter tip 40 can be less than or equal to 10mm.

[0061] Please see Figure 3 and Figure 6 In some embodiments, the atomizing assembly 100 includes a vent pipe 50, which is sleeved inside the atomizing tube 10. The outer wall of the vent pipe 50 and the inner wall of the atomizing tube 10 together define an accommodating space 101.

[0062] Thus, the vent pipe 50 and the inner wall of the atomizing tube 10 together define the accommodating space 101, thereby isolating the storage space of the liquid atomizing medium 300 and the flow path of the airflow carrying the aerosol. This is beneficial to improving the purity of the liquid atomizing medium 300 and the aerosol formed after atomization, and also effectively utilizes the internal space of the atomizing tube 10, which is conducive to a compact structure.

[0063] Specifically, both ends of the vent pipe 50 are open in the axial direction, and the openings at both ends of the vent pipe 50 can communicate with the external environment of the atomizing assembly 100. The vent pipe 50 can be coaxially arranged with the atomizing tube 10, and the cross-sectional profile of the vent pipe 50 matches the cross-sectional profile and size of the atomizing tube 10 accordingly, so that an accommodating space 101 is formed between the outer wall surface of the vent pipe 50 and the inner wall surface of the atomizing tube 10. For example, both the vent pipe 50 and the atomizing tube 10 are circular tubes, and the outer diameter of the vent pipe 50 is smaller than the inner diameter of the atomizing tube 10.

[0064] Please see Figure 3 , Figure 4 and Figure 6 In some embodiments, the heating element 20 is disposed inside the vent pipe 50, and the vent pipe 50 has an oil guide hole 51 on its wall. The oil guide hole 51 is used to guide the liquid atomizing medium 300 from the self-contained space 101 to the heating element 20.

[0065] Thus, by placing the heating element 20 in the vent pipe 50, and providing an oil guide hole 51 on the pipe wall of the vent pipe 50, the liquid atomizing medium 300 can flow from the accommodating space 101 to the heating element 20 through the oil guide hole 51 and be heated in the vent pipe 50. This isolates the heating and storage space of the liquid atomizing medium 300, improves the purity of the liquid atomizing medium 300, and the diameter of the oil guide hole 51 can also limit the flow rate of the liquid atomizing medium 300 into the vent pipe 50 to match the heating area of ​​the heating element 20, thereby facilitating sufficient heating.

[0066] Specifically, the vent pipe 50 includes a first pipe section 53 and a second pipe section 54. The radial dimension of the first pipe section 53 is larger than that of the second pipe section 54. The heating element 20 is disposed in the first pipe section 53. The outer wall surface of the first pipe section 53 can be spaced apart from or attached to the pipe wall of the vent pipe 50. The outer wall surface of the second pipe section 54 is spaced apart from the inner wall surface of the vent pipe 50 to accommodate the liquid atomizing medium 300.

[0067] Optionally, the heating element 20 is a tubular structure formed by a heating mesh surrounding it and is fitted inside the first pipe section 53. The heating element 20 can be coaxially arranged with the vent pipe 50 to improve the circumferential uniformity of the heating temperature field.

[0068] Optionally, an oil guide hole 51 is formed on the wall of the first pipe section 53 and is disposed radially opposite to the heating element 20 along the vent pipe 50. In this embodiment, the first pipe section 53 is spaced from the pipe wall of the vent pipe 50 so that the liquid atomizing medium 300 can flow into the oil guide hole 51.

[0069] The diameter of the oil guide hole 51 can be significantly smaller than the radial and / or axial dimensions of the accommodating space 101, so that the ratio of the flow rate of the liquid atomizing medium 300 passing through the oil guide hole 51 per unit time to the total storage capacity of the atomizing component 100 is small, thereby heating in small amounts and multiple times, avoiding excessive flow of liquid atomizing matrix to the heating element 20.

[0070] Optionally, there may be multiple oil guide holes 51, and multiple oil guide components 22 may be evenly distributed along the circumference of the vent pipe 50 so that the liquid atomizing medium 300 can penetrate into the heating element 20 more evenly along the circumference.

[0071] Please see Figure 3 , Figure 4 and Figure 6 In some embodiments, the atomizing component 100 includes an oil guide 22, which is wrapped around the heating element 20 and covers the oil guide hole 51. The oil guide 22 is used to adsorb liquid atomizing medium 300.

[0072] Thus, by wrapping the oil guide 22 around the heating element 20 and covering the oil guide hole 51, the oil guide 22 can adsorb the liquid atomizing medium 300 from the accommodating space 101 into the atomizing tube 10, and fix a small amount of liquid atomizing medium 300 around the heating element 20 for heating.

[0073] Specifically, the oil guiding component 22 can be made of high-temperature resistant fibers or porous materials that have a strong adsorption capacity for the liquid atomizing medium 300. For example, the oil storage component 80 can be made of organic cotton, degreased cotton, flax fiber, ceramic fiber or other synthetic fibers.

[0074] Optionally, the oil guide 22 is a flexible body, and the heating element 20 can be generally tubular and nested with the rigid support tube 23. The support tube 23 can be nested outside the heating element 20, and the oil guide 22 is wrapped around the support tube 23. The support tube 23 can be made of porous materials such as ceramics so that the liquid atomizing medium 300 adsorbed by the oil guide 22 can contact the heating element 20 through the support tube 23.

[0075] Optionally, the heating element 20, the support tube 23, and the oil guide 22 are sequentially arranged from the inside to the outside, one end of the lead wire 21 extends into the support tube 23 and is connected to the heating element 20, and the other end of the lead wire 21 is connected to the conductive terminal 30.

[0076] Please see Figure 3 , Figure 5 and Figure 6 In some embodiments, the filter tip 40 is formed with a first vent 41 communicating with the vent tube 50.

[0077] Thus, a first vent 41 is formed through the filter 40 and communicates with the vent tube 50, allowing the user to draw in the aerosol escaping along the vent tube 50 through the filter 40.

[0078] Specifically, the atomizing tube 10, the air vent 50, and the filter nozzle 40 can be coaxially arranged. The filter nozzle 40 covers the second end 12 of the atomizing tube 10. The first air vent 41 can pass through the filter nozzle 40 axially and be opposite to the atomizing tube 10 axially. The first air vent 41 can be directly connected to the air vent 50, or indirectly connected to the air vent 50 through holes, tubes, channels, etc. formed by other components.

[0079] The heating element 20 is disposed near the first end 11 in the ventilation tube 50. The heating element 20 draws liquid atomizing medium 300 from the accommodating space 101 outside the ventilation tube 50 through the oil guide 22 and the oil guide hole 51, and heats the liquid atomizing medium 300 inside the ventilation tube 50. The liquid atomizing medium 300 generates an aerosol when heated at the end of the ventilation tube 50 corresponding to the first end 11. The aerosol can flow upward along the ventilation tube 50 under the drive of the suction airflow, pass through the first ventilation hole 41 (filter 40) and enter the user's respiratory system.

[0080] Please see Figure 3 , Figure 5 and Figure 6 In some embodiments, the atomizing assembly 100 includes a mounting member 60, which is disposed at the second end 12 of the atomizing tube 10 in the axial direction and is used to block the accommodating space 101. The mounting member 60 has a second vent 62 that is opposite to and communicates with the vent tube 50. The filter tip 40 is stacked on the mounting member 60 and the first vent 41 communicates with the second vent 62.

[0081] Thus, by sealing the accommodating space 101 at the second end 12 with the mounting member 60, and by forming a second vent 62 that is opposite to and communicates with the vent pipe 50, the filter nozzle 40 is stacked on the mounting member 60 and the first vent 41 communicates with the second vent 62, thereby reducing the risk of leakage of the liquid atomizing medium 300.

[0082] Specifically, the mounting component 60 may be a block whose radial dimensions and profile shape match those of the atomizing tube 10. The mounting component 60 is fixedly connected to the atomizing tube 10 at its second end 12, and the outer peripheral surface of the mounting component 60 is sealed to the inner wall surface of the atomizing tube 10. The mounting component 60 may be connected to the atomizing tube 10 by at least one of the following methods: threaded connection, plug-in connection, snap-fit ​​connection, welding, riveting, sintering, clamp connection, flange connection, etc.

[0083] For example, the atomizing tube 10 is a round tube, the mounting member 60 is generally in the shape of a short cylinder, and the second vent hole 62 passes through the mounting member 60 axially. The outer peripheral surface of the mounting member 60 may be provided with a first sealing part 61, which may protrude radially outward. The mounting member 60 can achieve a sealed connection by the first sealing part 61 and the tube wall of the atomizing tube 10 through an interference fit.

[0084] Optionally, the atomizing tube 10 includes an end cap 13 located at the second end 12, which can be integrally connected to the tube wall of the atomizing tube 10. The end cap 13 forms a first through hole that is directly opposite to and communicates with the second vent 62. The mounting member 60 can be disposed inside the atomizing tube 10, and the upper end surface of the mounting member 60 can be tightly fitted with the side surface of the end cap 13 facing the receiving space 101.

[0085] The end of the vent pipe 50 corresponding to the second end 12 can partially extend into the second vent hole 62. The wall of the second vent hole 62 may be provided with a second sealing part 63, which is located in the section of the second vent hole 62 where it is inserted into the vent hole. The second sealing part 63 may protrude radially inward, and the mounting member 60 can achieve a sealed connection by interference fit between the second sealing part 63 and the outer wall surface of the vent pipe 50.

[0086] The filter tip 40 can be stacked on top of the mounting member 60 and fixedly connected to the mounting member 60. The first vent 41 and the second vent 62 can be axially aligned and connected. In some embodiments, the second end 12 of the atomizing tube 10 can be provided with an end cap 13, the mounting member 60 is located inside the atomizing tube 10 and abuts against the end cap 13 from inside the atomizing tube 10, and the filter tip 40 can be disposed outside the atomizing tube 10 and abut against the side surface of the end cap 13 opposite to the mounting member 60. The end cap 13 is provided with a first through hole to connect the first vent 41 and the second vent 62.

[0087] Optionally, the vent pipe 50 is coaxially arranged with the atomizing tube 10, and the vent pipe 50 is located at the axial center of the atomizing tube 10. Since the first vent hole 41 and the second vent hole 62 can both be axially aligned with and connected to the vent pipe 50, and the outer peripheral surface of the mounting member 60 is sealed to the inner wall surface of the atomizing tube 10, the second vent hole 62 is also located at the axial center of the mounting member 60. The filter nozzle 40 can be coaxial with the atomizing tube 10, and the filter nozzle 40 and the atomizing tube 10 have the same radial dimension; the first vent hole 41 is also located at the axial center of the filter nozzle 40.

[0088] Optionally, the diameter of the first vent 41 may be slightly smaller than that of the second vent 62, so that the escaped aerosol is more concentrated.

[0089] Optionally, the second vent 62 can form a first segment 621 and a second segment 622 with different diameters. The diameter of the first segment 621 is smaller than the diameter of the second segment 622. The wall of the second vent 62 has a discontinuity surface 623 at the connection between the first segment 621 and the second segment 622. The diameter of the first segment 621 can be slightly smaller than the inner diameter of the end of the vent tube 50 corresponding to the second end 12, and the diameter of the second segment 622 can be slightly smaller than or equal to the outer diameter of the end of the vent tube 50 corresponding to the second end 12. When the end of the vent tube 50 corresponding to the second end 12 is inserted into the second vent 62, it can be interference-fitted with the second segment 622. The vent tube 50 extends into the end face of the second segment 622 and abuts against the discontinuity surface 623 between the first segment 621 and the second segment 622, thereby playing a limiting role.

[0090] Please see Figure 3 , Figure 5 and Figure 6 In some embodiments, the mounting member 60 has an oil filling hole 64 communicating with the accommodating space 101, and the atomizing assembly 100 includes a seal 65 detachably connected to the mounting member 60, the seal 65 being used to block the oil filling hole 64.

[0091] Thus, by sealing the oil injection hole 64 with the sealing element 65 which is detachably connected to the mounting element 60, liquid atomizing medium 300 can be injected into the accommodating space 101 through the oil injection hole 64 during the assembly of the atomizing component 100, and the oil injection hole 64 is sealed after the liquid injection is completed. This improves the feasibility and convenience of manufacturing while maintaining the airtightness of the accommodating space 101.

[0092] Specifically, the seal 65 may extend into the oil filling hole 64 to block it. The shape and size of the outer contour of the cross-section of the seal 65 correspond to and match the shape and size of the oil filling hole 64, so that the outer surface of the seal 65 is in a sealing connection with the hole wall of the oil filling hole 64. For example, the oil filling hole 64 is a narrow circular hole, and the seal 65 is a circular needle-like structure. The diameter of the seal 65 may be equal to or slightly larger than the diameter of the oil filling hole 64.

[0093] Optionally, the second vent 62 is located at the geometric center of the mounting member 60 and extends radially through the mounting member 60.

[0094] Optionally, the second end 12 of the atomizing tube 10 may be provided with an end cap 13, which is integrally connected to the tube wall of the atomizing tube 10. The mounting member 60 is located inside the atomizing tube 10 and abuts against the end cap 13 from inside the atomizing tube 10. The filter nozzle 40 is disposed outside the atomizing tube 10 and abuts against the side surface of the end cap 13 away from the mounting member 60. The end cap 13 is provided with a first through hole and a second through hole. The first through hole is axially opposite to and connected to the first vent hole 41 and the second vent hole 62. The second through hole is axially opposite to and connected to the oil filling hole 64. The filter nozzle 40 can cover the second through hole.

[0095] Please see Figure 3 , Figure 4 and Figure 6 In some embodiments, the atomizing assembly 100 includes a base 70 disposed at a first end 11, and conductive terminals 30 are embedded in the base 70 and at least partially exposed outside the base 70.

[0096] Thus, by embedding the conductive terminal 30 on the base 70 and exposing it at least partially outside the base 70, the conductive terminal 30 is stably connected to the atomizing tube 10, and the conductive terminal 30 can be connected to the contact 220 on the aerosol generating device 200 through the exposed part, thereby enabling the heating element 20 to establish a connection with the aerosol generating device 200 when the atomizing component 100 is installed in the aerosol generating device 200.

[0097] Specifically, the base 70 can be inserted into the opening of the first end 11 and sealed to the inner wall of the atomizing tube 10. The base 70 can be fixedly connected to the atomizing tube 10 by at least one of the following methods: threaded connection, plug-in connection, snap-fit ​​connection, clamp connection, flange connection, welding, riveting, sintering, etc. The lower end face of the base 70 protrudes outside the atomizing tube 10, and a mounting hole 71 can be formed on the lower end face of the base 70 for mounting the conductive terminal 30. The conductive terminal 30 can be partially accommodated in the mounting hole 71 and partially protrude beyond the lower end face of the base 70 and protrude outside the mounting hole 71.

[0098] The heating element 20 can be connected to one end of the lead wire 21, which can be passed through the base 70 and the other end of the lead wire 21 extends into the mounting hole 71 and is connected to the conductive terminal 30.

[0099] Optionally, the number of conductive terminals 30 can be two, with each of the two conductive terminals 30 connected to a lead 21, and each of the two conductive terminals 30 can be connected to the two poles of the power supply circuit 230. Correspondingly, the number of mounting holes 71 can also be two, and the two mounting holes 71 can be arranged radially opposite each other to make the spacing between the two conductive terminals 30 larger.

[0100] Optionally, the base 70 may also be provided with a magnet 76, which is used to generate magnetic attraction when the atomizing component 100 is connected to the aerosol generating device 200, thereby strengthening the connection between the atomizing component 100 and the aerosol generating device 200. The magnet 76 may also be embedded in the lower end face of the base 70.

[0101] Optionally, the base 70 and the mounting piece 60 can respectively block the receiving space 101 at the first end 11 and the second end 12.

[0102] Please see Figure 3 and Figure 6 In some embodiments, the atomizing assembly 100 includes a vent pipe 50, which communicates with the external environment and is fitted inside the atomizing tube 10. The outer wall of the vent pipe 50 and the inner wall of the atomizing tube 10 together define an accommodating space 101. The base 70 has a third vent hole 73 that communicates with the vent pipe 50.

[0103] Thus, a third vent 73 is formed by the base 70 and communicates with the vent tube 50. The outer wall of the vent tube 50 and the inner wall of the atomizing tube 10 together define the accommodating space 101, so that the air from the external environment can enter the atomizing component 100 from the first end 11 of the atomizing tube 10 and mix with the aerosol. Then the airflow carrying the aerosol can flow upward until it is inhaled by the user through the filter 40.

[0104] Specifically, the base 70 can be inserted into the opening of the first end 11 and support the vent tube 50. The base 70 is sealed to the vent tube 50 and the atomizing tube 10 respectively, so that the suction airflow can only enter the vent tube 50 from the third vent hole 73, thus ensuring the airtightness of the accommodating space 101.

[0105] The base 70 may include a sealing portion 74 and a mounting portion 75 connected axially. The sealing portion 74 extends between the walls of the atomizing tube 10 and the venting tube 50, and forms protrusions facing the walls of the atomizing tube 10 and the venting tube 50, respectively, to provide an interference fit with the venting tube 50 and the atomizing tube 10 on their inner and outer radial sides, respectively. The mounting portion 75 abuts against the end face of the venting tube 50 corresponding to the first end 11, and a third vent hole 73 is formed within the area directly opposite the mounting portion 75 and the venting tube 50. The side of the mounting portion 75 away from the sealing portion 74 may be partially exposed outside the atomizing tube 10, and a conductive terminal 30 is provided on the side of the mounting portion 75 away from the sealing portion 74.

[0106] The conductive terminal 30 and the magnetic body 76 can be positioned radially between the edge of the third vent hole 73 and the outer peripheral surface of the base 70. The conductive terminal 30 and the magnetic body 76 can be arranged sequentially at intervals along the circumference of the base 70.

[0107] Please see Figure 3 and Figure 6 In some embodiments, the atomizing component 100 includes an oil reservoir 80, in which the liquid atomizing medium 300 is stored, and the oil reservoir 80 is housed in a receiving space 101.

[0108] In this way, the oil storage component 80 adsorbs the liquid atomizing medium 300 and is housed in the accommodating space 101, thereby reducing the risk of leakage.

[0109] Specifically, the oil reservoir 80 can be a thick-walled, soft tubular structure. The oil reservoir 80 can be made of heat-resistant fibers or porous materials. For example, the oil reservoir 80 can be made of organic cotton, degreased cotton, flax fiber, ceramic fiber, or other synthetic fibers.

[0110] In some embodiments, the vent pipe 50 is sleeved inside the atomizing tube 10, with the wall of the vent pipe 50 and the wall of the atomizing tube 10 radially spaced and opposite to each other. The base 70 and the mounting member 60 are respectively sealed to the first end 11 and the second end 12, as well as the ends of the vent pipe 50 corresponding to the first end 11 and the second end 12. The lower end face of the mounting member 60 and the upper end face of the base 70 are axially opposite to each other. The outer wall surface of the vent pipe 50, the inner wall surface of the atomizing tube 10, the lower end face of the mounting member 60, and the upper end face of the base 70 together form an accommodating space 101. The oil storage member 80 may be filled in the accommodating space 101, and the oil storage member 80 may be in contact with or at least in contact with the outer wall surface of the vent pipe 50, the inner wall surface of the atomizing tube 10, the lower end face of the mounting member 60, and the upper end face of the base 70.

[0111] Please see Figure 7 The aerosol generating device 200 is a structure that can generate aerosols by acting on the atomizing medium through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound or mechanical vibration.

[0112] The aerosol generating device 200 of this application includes a housing 210 and contacts 220, wherein:

[0113] The housing 210 has a receiving cavity 211 for accommodating the atomizing component 100 of any of the above embodiments;

[0114] Contact 220 is disposed on housing 210. Contact 220 is used to connect to conductive terminal 30 of atomizing assembly 100 when atomizing assembly 100 is installed in receiving cavity 211, so that heating element 20 of atomizing assembly 100 can start heating.

[0115] The aerosol generating device 200 of this embodiment is used in conjunction with the atomizing assembly 100 to generate aerosols. A heating element 20 is housed within the atomizing tube 10 and electrically connected to a conductive terminal 30. The conductive terminal 30 connects to a contact 220 after the atomizing assembly 100 is inserted into the aerosol generating device 200, allowing the aerosol generating device 200 to control the heating and atomization process of the atomizing assembly 100. After the atomizing assembly 100 is inserted into the receiving cavity 211 and the heating element 20 begins heating, the user can inhale through the filter nozzle 40, improving the ease of use of the atomizing assembly 100.

[0116] Specifically, the aerosol generating device 200 also includes a power supply circuit 230, a control component 240, etc. The power supply circuit 230 and the control component 240 are both connected to the contact 220, and can be electrically connected to the heating element 20 after the contact 220 is connected to the conductive terminal 30, so that the user can control the heating state of the heating element 20 by operating the aerosol generating device 200.

[0117] Contact 220 is located on the bottom surface of receiving cavity 211. When atomizing assembly 100 extends into receiving cavity 211, contact 220 and conductive terminal 30 are opposite each other along the axial direction of atomizing assembly 100. The number of contacts 220 is the same as the number of conductive terminals 30, and each contact 220 abuts against and conducts with a corresponding conductive terminal 30.

[0118] Optionally, combined Figure 1 The outer casing 90 may be provided with a marking part 91, which can be formed on the outer casing 90 by means of pasting, printing, writing, adsorption, engraving, etc. The marking part 91 may be in the shape of a ring, and the atomizing component 100 below the marking part 91 is a recessed part 92, which can be completely submerged in the receiving cavity 211, while the part above the marking part 91 is exposed outside the receiving cavity 211.

[0119] In some embodiments, the aerosol generating device 200 may also be compatible with a heated solid atomizing medium (not shown). The solid atomizing medium can be directly inserted into the receiving cavity 211, and the portion of the solid atomizing medium inserted into the receiving cavity 211 has the same size and outer contour shape as the submerged portion 92 of the atomizing component 100. The solid atomizing medium can be prepared into a cylindrical structure using processes such as rolling, slurry preparation, die casting, and extrusion.

[0120] In some implementations, combined Figure 6The atomizing assembly 100 includes a connector detachably connected to the aerosol generating device 200. Exemplarily, the connector is detachably connected to the housing 210 by magnetic force. The connector can be a magnetic body 76 or a component made of iron or an iron-containing alloy. When the connector is a magnetic body 76, the housing 210 has a magnetic component with the opposite magnetic properties to the magnetic body 76, or the bottom surface of the receiving cavity 211 is made of iron or an iron-containing alloy. When the atomizing assembly 100 extends into the receiving cavity 211, and the base 70 gradually approaches the bottom surface of the receiving cavity 211, the magnetic attraction force on the magnetic body 76 gradually increases until the magnetic body 76 and the magnetic component on the housing 210 attract each other. The detachable connection between the connector and the housing 210 increases the connection strength between the atomizing assembly 100 and the housing 210, and also facilitates assembly and disassembly.

[0121] Optionally, combined Figure 3 and Figure 6 In one specific embodiment, the assembly process of the atomizing component 100 includes the following steps:

[0122] (1) The heating element 20 is fixedly connected to one end of the lead wire 21, and the heating element 20, the support tube 23 and the oil guide 22 are sequentially arranged from the inside to the outside;

[0123] (2) Insert the module formed in step (1) into the first section 53 of the vent pipe 50, with the lead wire 21 at least partially exposed outside the vent pipe 50.

[0124] (3) Embed the conductive terminal 30 and the magnetic body 76 into the base 70, pass the other end of the lead wire 21 through the base 70 and connect it to the conductive terminal 30, and put the base 70 containing the conductive terminal 30 and the magnetic body 76 onto the end of the vent pipe 50 corresponding to the first end 11.

[0125] (4) Fill the mounting part 60 into the second end 12 of the atomizing tube 10, and put the module formed in step (3) and the oil storage part 80 that has not absorbed the liquid atomizing medium 300 into the atomizing tube 10 from the first end 11. The oil storage part 80 covers the outside of the vent pipe 50 and is stored in the accommodating space 101.

[0126] (5) Inject liquid atomizing medium 300 into the oil injection hole 64 so that the oil storage component 80 is filled with liquid atomizing medium 300;

[0127] (6) Place the filter tip 40 at the second end 12 of the atomizing tube 10 and put the outer shell 90 over the atomizing tube 10 and the filter tip 40.
