The first end of the conductive member is fixedly connected to the heating element, and the second end of the conductive member is fixed and sealedly connected to the sealing cover, so that the heating element is fixed relative to the sealing component, and the sealing component isolates the heating component from the external environment, thereby improving the thermal insulation capacity of the aerosol generating device and effectively reducing the heat transfer of the heating component to the outside.

[0009] In some embodiments, the sealing cylinder, the sealing cover and the receiving component form a vacuum space, and the heating element is disposed in the vacuum space.

[0010] In this way, the sealing cylinder, the sealing cover and the accommodating part form a closed vacuum zone, and the heating element is arranged in the vacuum zone, so that the vacuum zone has a good heat insulation effect on the heating element, further reduces the heat transfer of the heating component to the outside, and improves the heat utilization rate.

[0011] In some embodiments, the heating component is generally cylindrical in shape, the accommodating component includes a cylindrical body with an opening, and the heating element is sleeved outside the accommodating component.

[0012] In this way, the accommodating part includes a cylindrical body, the heating element is sleeved outside the accommodating part, and the heating component as a whole is roughly cylindrical, so that the overall structure of the heating component is relatively compact, the shape is simple and easy to manufacture, and it is conducive to the insertion and uniform heating of the atomized medium.

[0013] In some embodiments, the heating element is in a spiral shape and is conductive, and is used to generate heat energy when electricity is supplied.

[0014] In this way, the heating element is conductive and has a spiral shape. On the one hand, when the heating element is energized, a circumferential temperature field can be formed to heat the atomized medium, and the heating uniformity is better. On the other hand, electromagnetic induction is used to enable the heating element to generate a magnetic field.

[0022] In this way, a second heat reflecting layer is provided on the surface of the vacuum area enclosed by the sealing component, so that the second heat reflecting layer can reflect the heat generated by the heating element toward the container, thereby further reducing heat loss and improving the heat utilization rate and heating efficiency of the heating component in heating the atomizing medium.

[0023] In some embodiments, the portion of the receiving component facing the heating element is transparent.

[0024] In this way, the portion of the accommodating component facing the heating element is transparent, which helps the heat generated by the heating element to pass through the accommodating component and radiate to the atomized medium in the accommodating component, thereby improving thermal efficiency.

[0041] The aerosol generating device 100 is a structure that can generate aerosols by acting on an atomizing medium through resistance heating, electromagnetic heating, etc. The atomizing medium is a substance that has been processed and heated to produce an aerosol.

The aerosol may be visible or invisible and may include steam (for example, fine particulate matter in a gaseous state, which is usually liquid or solid at room temperature) and liquid droplets of gas and condensed steam. The aerosol may contain volatile compounds. The user can inhale the aerosol into the oral cavity, nasal cavity or lungs through the mouth or nose. The aerosol inhaled into the user's respiratory system can be used for various purposes such as food, medicine, health care, and entertainment.

[0042] The atomized medium may be in a solid or semi-solid state, or in a liquid state. For example, a solid atomized medium may be a plant flower, stem, or leaf product prepared by roller pressing, slurrying, die casting, extrusion, or other processes. For another example, a liquid atomized medium may include a liquid composition based on plant extracts and / or various flavoring agents.

[0044] In the aerosol generating device 100 of the embodiment of the present application, the sealing component 20 is covered outside the accommodating part 11 and is sealed and fixedly connected to the accommodating part 11. The first end 41 of the conductive member 40 is fixedly connected to the heating element 12, and the second end 42 of the conductive member 40 is fixed and sealedly connected to the sealing component 20, so that the heating element 12 is fixed relative to the sealing component 20, and the sealing component 20 isolates the heating component 10 from the external environment, thereby improving the thermal insulation capacity of the aerosol generating device 100 and effectively reducing the heat transfer of the heating component 10 to the outside.

[0045] Specifically, the container 11 can be a hollow tube, column, cylinder or other block structure, and the hollow space inside the container 11 is the receiving space 110. The atomized medium can be loaded into the receiving space 110 when the customer needs it, or it can be pre-installed in the receiving space 110.

[0046] Optionally, the container 11 is a cylindrical structure, and an opening 114 is formed at one end of the container 11. The wall of the container 11 separates the accommodating space 110 from the external environment of the container 11. The atomized medium can be a solid medium and is columnar, and the atomized medium is inserted into the container 11 from the opening 114 of the container 11. The cross-sectional shape of the container 11 can be circular, elliptical, triangular, square, diamond, polygonal, runway-shaped, olive-shaped, star-shaped or other irregular shapes, and this application does not limit this. Exemplarily, the cross-sectional shape of the container 11 is circular, and the container 11 is a hollow cylinder. Optionally, an opening 114 is formed at one of the two ends along the axial direction of the container 11, and the other end has a closed bottom wall.

[0048] Optionally, the heating element 12 is disposed around the outer periphery of the container 11 to improve heating efficiency and enhance circumferential uniformity of the temperature field. The heating element 12 can be made of wire, plate, sheet, film, etc. and can be made into a strip, sheet, or three-dimensional tubular structure.

[0049] The conductive member 40 includes a first end 41 and a second end 42. The first end 41 is fixed to the heating element 12 and can connect electricity to the heating element 12. The second end 42 is provided in the sealing assembly 20. The second end 42 can pass through one of the sealing cylinder 21 and the sealing cover 23, or pass through between the sealing cylinder 21 and the sealing cover 23. The second end 42 is fixed and sealed to the sealing assembly 20, which means that the connection between the second end 42 and the sealing cylinder 21 and / or the sealing cover 23 is tightly connected without a gap, and can even be partially blended together at the connection. The heating element 12 is connected to the external circuit through the conductive member 40, and the auxiliary heating element 12 is fixed in a fixed position outside the container 11, so as to achieve stable heating.

[0050] The present application does not limit the conductive member 40 to structures such as a wire, sheet, plate, or film. Optionally, the conductive member 40 is a lead wire, with the first end 41 being one end of the lead wire along its length. The first end 41 can be clamped or wound around the heating element 12. The second end 42 can be located between the two ends of the lead wire along its length and close to the other end of the lead wire that is distinct from the first end 41 along its length.

[0051] Optionally, in Figure 4 In the illustrated embodiment, the second end 42 passes between the sealing cylinder 21 and the sealing cover 23 and is sintered with the sealing cover 23 to form an integral structure.

[0052] In other embodiments, the second end 42 may also be inserted through the sealing cylinder 21 or the sealing cap 23. In this embodiment, a through-hole may be formed in the sealing assembly 20 to allow the conductive member 40 to pass through, and the sealing assembly 20 cooperates with the conductive member 40 at the through-hole to seal the through-hole. The conductive member 40 is fixedly connected to the sealing assembly 20 at the through-hole and can be connected to form an integral structure.

[0053] Optionally, there are two conductive members 40, each of which is fixedly connected to the two axial ends of the heating element 12 and connected to the two output ends of the external circuit. Furthermore, one of the two second ends of the two conductive members 40 can pass through the sealing cylinder 21, the sealing cover 23, or between the sealing cylinder 21 and the sealing cover 23, and the other can also pass through the sealing cylinder 21, the sealing cover 23, or between the sealing cylinder 21 and the sealing cover 23. Exemplarily, both second ends 42 pass through the sealing cover 23, and the heating element 12 and the sealing cover 23 are relatively fixed by the conductive members 40.

[0054] See also Figure 2 、 Figure 3 and Figure 5 In some embodiments, the sealing cylinder 21, the sealing cover 23 and the container 11 form a vacuum space 30, and the heating element 12 is disposed in the vacuum space 30.

[0055] In this way, a sealed vacuum space 30 is formed by the sealing tube 21, the sealing cover 23 and the accommodating part 11, and the heating element 12 is arranged in the vacuum space 30, so that the vacuum space 30 has a good heat insulation effect on the heating element 12, further reducing the heat transfer to the outside of the heating component 10 and improving the heat utilization rate.

[0056] Specifically, the outer wall of the accommodating member 11, the inner wall of the sealing tube 21, and the inner surface of the sealing cover 230 define a vacuum zone 30. This zone is evacuated to a vacuum state, isolating the high-temperature heating element 12 from the exterior of the sealing assembly 20 and reducing heat loss. The first end 41 and the portion of the conductive member 40 between the first end 41 and the second end 42 are located within the vacuum zone 30.

[0057] See also Figure 2-Figure 5 In some embodiments, the heating component 10 is generally cylindrical in shape, the receiving component 11 includes a cylindrical body 112 having an opening 114 , and the heating element 12 is sleeved outside the receiving component 11 .

[0058] In this way, the accommodating part 11 includes a cylindrical body 112, and the heating element 12 is sleeved outside the accommodating part 11. The heating component 10 is generally cylindrical, so that the overall structure of the heating component 10 is relatively compact, the shape is simple and easy to manufacture, and it is conducive to the insertion and uniform heating of the atomized medium.

[0059] Specifically, the heating element 12 is generally cylindrical in shape. The cross-sectional shape of the heating element 12 may be, but is not limited to, circular, elliptical, triangular, square, rhombus, polygonal, racetrack-shaped, olive-shaped, star-shaped, or other irregular shapes. The cross-sectional shape of the heating element 12 may be the same as or different from that of the accommodating member 11.

[0060] Exemplarily, the heating element 12 is a cylindrical structure formed by winding a wire around the accommodating part 11 . The cross-sectional shapes of the accommodating part 11 and the heating element 12 are both circular, and this shape design is conducive to uniform heating.

[0061] An opening 114 is formed at at least one of the axial ends of the cylinder 112. For example, a first opening 1141 and a second opening 1142 are formed at the axial ends of the cylinder 112, respectively. The cylinder 112 can be cylindrical, and the first opening 1141 and the second opening 1142 are both circular. The cylinder 112 mates with the two ends of the sealing assembly 20 at the first opening 1141 and the second opening 1142, respectively, to seal and securely connect. The heating element 12 is disposed around the outer circumference of the cylinder 112, and the heating element 12 can extend from the end where the first opening 1141 is located to the end where the second opening 1142 is located to increase the heating area.

[0062] Optionally, the two axial ends of the cylinder 112 are respectively sealed and fixedly connected to the two axial ends of the sealing assembly 20 , the vacuum zone 30 is formed between the outer wall of the cylinder 112 and the sealing assembly 20 , and the heating element 12 is attached to the outer wall of the cylinder 112 .

[0063] See also Figure 4 and Figure 5 In some embodiments, the heating element 12 is in a spiral shape and is conductive. The heating element 12 is used to generate heat energy when electricity is supplied.

[0064] In this way, because the heating element 12 is conductive and has a spiral shape, on the one hand, when the heating element 12 is energized, a circumferential temperature field can be formed to heat the atomized medium, and the heating uniformity is better. On the other hand, electromagnetic induction is used to enable the heating element 12 to generate a magnetic field. The heating element 12 can replace the induction coil and the sensing element, thereby simplifying the structure of the heating component 10.

[0065] Specifically, the heating element 12 is a wire. The heating element 12 extends spirally along the axial direction of the accommodating member 11 outside the accommodating member 11, and the heating element 12 as a whole can be solenoid-shaped. The two axial ends of the heating element 12 are respectively connected to two conductive members 40, and the positive and negative poles of the circuit are connected through the conductive members 40 at both ends. The conductive members 40 can clamp or wrap around the ends of the heating element 12 to securely connect to the heating element 12.

[0066] Optionally, the heating element 12 is made of metal, for example, the heating element 12 can be a metal wire, a metal conductor, a metal coating, etc. For another example, the heating element 12 can be a flat wire, a round wire, or other wires with irregular cross sections.

The sealing cover 23 is disposed on the first opening 211 and / or the second opening 212 .

[0068] In this way, the first opening 211 and the second opening 212 are formed at the two axial ends of the sealing cylinder 21 respectively, and the sealing cover 23 is covered on the first opening 211 and / or the second opening 212, so that the heating component 10 can be installed into the sealing cylinder 21 from the first opening 211 or the second opening 212, which is convenient for assembling the heating component 10 and the sealing component 20; the sealing cylinder 21 surrounds the cylinder body 112 to ensure that the sealing component 20 plays a role in isolating the circumferential heat transfer of the heating component 10.

[0069] Specifically, the sealing cylinder 21 surrounds the cylindrical body 112. The inner surface of the sealing cylinder 21, the outer surface of the cylindrical body 112, and the upper surface (or lower surface) of the sealing cover 23 define a vacuum zone 30. The wall of the sealing cylinder 21 is spaced a certain distance from the wall of the cylindrical body 112 to form a vacuum zone 30 of sufficient thickness. The accommodating member 11 can be inserted into the sealing cylinder 21 through the first opening 211 and / or the second opening 212. The axial ends of the cylindrical body 112 correspond to the first opening 211 and the second opening 212, respectively.

[0070] For ease of explanation, the direction from the first opening 211 to the second opening 212 along the axial direction of the sealing cylinder 21 is defined as the bottom-to-top direction. For example, the sealing cover 23 covering the first opening 211 is used as an example. The sealing cover 23 is sealed and fixedly connected to both the sealing cylinder 21 and the cylinder body 112. The upper side of the sealing cover 23 encloses a partial vacuum zone 30.

[0071] Optionally, the sealing cover 23 is formed with a mounting hole 231, and the lower end of the cylinder 112 is mounted in the mounting hole 231. The mounting hole 231 can be flush with the first opening 211. The outer periphery of the sealing cover 23 is sealed and fixedly connected to the lower end of the sealing cylinder 21. The sealing cover 23 is sealed and fixedly connected to the lower end of the cylinder 112 at the edge of the mounting hole 231.

[0072] Furthermore, the cylindrical body 112 has a first opening 1141 and a second opening 1142 formed at both axial ends, respectively. The end of the cylindrical body 112 with the first opening 1141 can be flush with the end of the sealing cylinder 21 with the first opening 211. The first opening 1141, the mounting hole 231, and the first opening 211 can be coplanar. The second opening 1142 is located above the first opening 1141, and the end of the cylindrical body 112 with the second opening 1142 can be connected to the end of the sealing cylinder 21 with the second opening 212.

[0073] Optionally, the two axial ends of the heating element 12 are electrically connected to the two conductive members 40, and the second ends 42 of the two conductive members 40 can both pass through the vacuum space 30 through the first opening 211. Optionally, the second ends 42 of the two conductive members 40 can both pass through the vacuum space 30 through the second opening 212, or can pass through the vacuum space 30 through the first opening 211 and the second opening 212 respectively.

[0074] See also Figure 2-Figure 5 In some embodiments, the container 11 is provided with a flange 116, the flange 116 is opposite to the sealing cover 23 along the axial direction of the container 11, the flange 116 is sealed and fixedly connected to the sealing cylinder 21, and the flange 116, the cylinder 112, the sealing cover 23 and the sealing cylinder 21 together form a vacuum zone 30.

[0075] In this way, the flange 116 and the sealing cover 23 are opposite to each other along the axial direction of the container 11, and the flange 116 and the sealing cylinder 21 are sealed and fixedly connected, so that the flange 116 is covered at one end of the vacuum zone 30 and ensures the sealing of the end of the vacuum zone 30.

[0076] Specifically, the container 11 includes a flange 116 and a cylindrical body 112. The flange 116 can be disposed at an axial end of the container 11. The flange 116 can be connected to an end of the cylindrical body 112 having the second opening 1142, extend radially outward from the cylindrical body 112, abut against the sealing cylinder 21, and be sealed and fixedly connected to the end of the sealing cylinder 21 having the second opening 212.

[0077] In this embodiment, the vacuum zone 30 surrounds the cylinder 112 , and the vacuum layer can be used to isolate the heat of the heating element 12 at each position in the circumference of the cylinder 112 , thereby reducing heat transfer to the outside.

[0078] Optionally, in one example, the assembly process of the aerosol generating device 100 is as follows: (1) the second end 42 of the conductive member 40 passes through the sealing cover 23 and is nested and sintered with the sealing cover 23 to form an integral structure; the second end 42 can pass through the sealing cover 23 from top to bottom, and the first end 41 is located above the sealing cover 23; (2) the second end 42 of the conductive member 40 forms a barb and clamps the heating element 12, so that the sealing cover 23, the conductive member 40 and the heating element 12 are fixedly connected, and the heating element 12 is a solenoid; (3) The heating element 12 is sleeved on the container 11, and the sealing cover 23 is sintered together with the lower end of the cylinder 112, so that the container 11, the sealing cover 23, the conductive member 40 and the heating element 12 are all fixedly connected; (4) the integral assembly assembled in step (4) is sleeved into the sealing cylinder 21, and the axial ends of the sealing cylinder 21 are sintered together with the flange 116 and the outer periphery of the sealing cover 23 respectively, and the area surrounded by the flange 116, the cylinder 112, the sealing cover 23 and the sealing cylinder 21 is vacuumed to form a vacuum area 30.

[0079] See also Figure 2 and Figure 4 In some embodiments, a first heat reflective layer 1160 is provided on the surface of the vacuum space 30 enclosed by the flange 116 .

[0080] In this way, the heat radiation emitted by the heating element 12 and directed toward the flange 116 is reflected into the receiving component 11 by the first heat reflection layer 1160 , thereby reducing heat loss at the flange 116 and further improving the heat insulation capacity of the vacuum area.

[0081] Specifically, the first heat reflective layer 1160 can be made of a metal, alloy, or metal-based composite material and is formed on the surface of the vacuum area enclosed by the sealing component 20 through a deposition, coating, plating, or other process. For example, the surface of the sealing component 20 facing the receiving component 11 is plated with gold, and the gold plating forms the first heat reflective layer 1160.

[0082] In some embodiments, the portion of the receiving component 11 facing the heating element 12 is transparent.

[0083] In this way, the portion of the accommodating component 11 facing the heating element 12 is transparent, which helps the heat generated by the heating element 12 to pass through the accommodating component 11 and radiate to the atomized medium in the accommodating component 11, thereby improving thermal efficiency.

[0084] Optionally, the accommodating component 11 is entirely transparent. For example, the accommodating component 11 may be made of transparent glass, and the heat generated by the heating element 12 can easily penetrate the accommodating component 11 .

[0085] Optionally, the axial ends of the container 11 may be opaque, while the middle portion of the container 11 may be transparent. The heating element 12 is disposed around the middle portion of the container 11 and heats the atomized medium through the transparent portion. Furthermore, the transparent and opaque portions of the container 11 may be integrally formed or may be separate components sintered together to form a single, integrated container 11.

[0086] See also Figure 2 and Figure 4 In some embodiments, a second heat reflective layer 25 is provided on the surface of the vacuum area enclosed by the sealing component 20 .

[0087] In this way, a second heat reflecting layer 25 is provided on the surface of the vacuum area enclosed by the sealing component 20, so that the second heat reflecting layer 25 can reflect the heat generated by the heating element 12 toward the accommodating component 11, thereby further reducing heat loss and improving the heat utilization rate and heating efficiency of the heating component 10 in heating the atomized medium.

[0088] Specifically, the second heat reflective layer 25 can be made of a metal, alloy, or metal-based composite material and is formed on the surface of the sealing assembly 20 enclosed by the vacuum region through processes such as deposition, coating, and plating. For example, the surface of the sealing assembly 20 facing the accommodating member 11 is plated with silver, and the silver coating forms the second heat reflective layer 25. The first heat reflective layer 1160 and the second heat reflective layer 25 can be made of the same or different materials. For ease of production, the first heat reflective layer 1169 and the second heat reflective layer 25 can be made of the same material, for example, both the first heat reflective layer 1169 and the second heat reflective layer 25 are plated with gold.

[0089] In some embodiments, the sealing assembly 20 and the receiving component 11 are both quartz tubes, and the sealing assembly 20 and the receiving component 11 are sintered into an integral structure.

[0090] In this way, the sealing assembly 20 and the receiving component 11 are sintered into an integral structure, thereby ensuring the sealing of the vacuum area, while reducing the number of parts and improving the manufacturing and assembly efficiency.

[0091] Specifically, the sealing assembly 20 is sleeved outside the accommodating part 11. The sealing assembly 20 and the accommodating part 11 can be coaxial quartz tubes to improve the uniformity of the temperature field around the heating component 10. The sealing assembly 20 can be an integrally formed quartz tube, or a quartz tube body composed of two or more sub-components. For example, the sealing assembly 20 is composed of two quartz sub-components separated on the left and right, and the accommodating part 11 is placed between the two sub-components. The accommodating part 11 and the two sub-components are connected to form a whole through a sintering process. The accommodating part 11 can be a partially or completely transparent quartz tube or glass tube.

[0092] The cross-sectional shapes of the sealing component 20 and the accommodating member 11 may be the same or different; the cross-sectional shape of the sealing component 20 may be, but is not limited to, circular, elliptical, triangular, square, polygonal, runway-shaped, olive-shaped, star-shaped, and the like; the cross-sectional shape of the sealing component 20 may also be a combination of the above shapes or other irregular shapes.

[0093] Illustratively, the sealing cylinder 21 is a cylinder, the sealing cover 23 is an annular structure, the center line of the sealing cylinder 21 can pass through the circle of the sealing cover 23, and the sealing cylinder 21 and the sealing cover 23 can be coaxial with the accommodating component 11.

[0094] In the aerosol generating device 100 of the embodiment of the present application, the outer side of the accommodating part 11 and the sealing component 20 form a vacuum space 30, and the heating element 12 is arranged in the vacuum space 303, thereby reducing the heat transfer from the heating component 10 to the outside, improving the heat utilization rate, and having high sealing reliability. At the same time, the accommodating part 11 and the sealing component 20 are connected as one body, and the conductive part 40, the heating element 12 and the sealing component 20 can also be connected as one body, which greatly reduces the number of parts, simplifies the shape, and improves the manufacturing and assembly efficiency.
