Technical Field

[0001] This utility model relates to the field of electronic atomization technology, specifically to a heating element, a heating component, and an aerosol generating device. Background Technology

[0002] Heated tobacco products (HNB) are one of the two main categories of electronic cigarettes. HNB devices have a heating chamber into which a cigarette can be inserted. When in use, the cigarette is inserted into the heating chamber, and the heating tube inside the heating chamber heats the circumference of the cigarette to bake it and form an aerosol.

[0003] In existing technologies, in order to achieve different heating modes and meet the diverse needs of users, the heating element is divided into multiple heating zones. However, the heating chamber of the heated non-combustible tobacco device is a cylindrical cavity, and the contact between the tobacco stick and the inner wall of the heating chamber is not tight enough, resulting in a slower smoke output speed when heating in different zones, which affects the user's smoking experience. Utility Model Content

[0004] This invention provides a heating element, a heating component, and an aerosol generating device to solve the problem of slow smoke emission during heating.

[0005] In one embodiment, a heating element is provided, comprising:

[0009] In one embodiment, the heating element is an elliptical tube, the minimum inner diameter of the heating element is smaller than the outer diameter of the atomizing matrix, and the maximum inner diameter of the heating element is larger than the outer diameter of the atomizing matrix.

[0010] In one embodiment, the heating element is divided into a first heating zone and a second heating zone along the surface where the maximum inner diameter of the heating element is located.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0036] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0037] The component numbers used in this document, such as "first" and "second," are merely for distinguishing the described objects and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" in this application include both direct and indirect connections (linkages). The up-down direction in this document refers to the direction in the user's operating state.

[0038] In one embodiment, a heating element is provided, which is an important component of an aerosol generating device. The aerosol generating device is a heated non-combustible tobacco device. The heating element is used to insert an atomizing matrix (cigarette) and heat and bake the atomizing matrix circumferentially to form an aerosol.

[0039] The heating element's heating tube is an irregularly shaped tube. Compared to a conventional circular tube, the inner diameter of a portion of the irregularly shaped tube is smaller, and also smaller than the outer diameter of the atomizing substrate. When the atomizing substrate is inserted into the heating tube, the atomizing substrate is deformed by the smaller inner diameter portion of the heating tube, causing the outer wall of this portion of the atomizing substrate to adhere tightly to the inner wall of the heating tube. This increases the contact area between the atomizing substrate and the heating tube, effectively improving the heating efficiency of the heating tube on the atomizing substrate.

[0040] The heating element is also equipped with zoned heating, and can be divided into at least two heating zones. Each heating zone can be heated independently, or multiple heating zones can be heated simultaneously. Each heating zone is equipped with at least one independent heating element, which serves as the heat source. The heating element is located in or near the area with the smallest inner diameter of the heating element, so that after the atomizing matrix is ​​inserted into the heating element, the deformation of the atomizing matrix fits the heating element radially aligned with the heating element. There is a small gap between the atomizing matrix and the heating element, allowing the heating element to transfer heat to the atomizing matrix more quickly, achieving rapid smoke emission from the atomizing matrix.

[0041] Please refer to Figure 1 and Figure 2 In this embodiment, the heating element 10 mainly includes a heating tube 1 and a heating component 2. The heating tube 1 is made of a material with good thermal conductivity, such as thermally conductive metals or ceramics. The heating component 2 is a heat source and includes, but is not limited to, printed metal sheets or metal wires. The heating component 2 has positive and negative terminals and can be connected to a circuit board via wires to form a heating circuit. The heating component 2 is used to convert electrical energy into heat energy. The heating component 2 and the heating tube 1 are integrated into a single structure, which can achieve heating of the atomized matrix.

[0042] Heating tube 1 is an irregularly shaped tube, preferably an elliptical tube. The cavity inside heating tube 1 forms an elliptical cylindrical cavity. The inner diameter of heating tube 1 includes a minimum inner diameter and a maximum inner diameter. At the minimum inner diameter, the two inner walls of heating tube 1 are closer together, while at the maximum inner diameter, the two inner walls are farther apart. Specifically, the minimum inner diameter of heating tube 1 is smaller than the outer diameter of the atomizing substrate, and the maximum inner diameter of heating tube 1 is larger than the outer diameter of the atomizing substrate. This ensures that after the atomizing substrate is inserted into heating tube 1, it is compressed in the direction of the minimum inner diameter and extended in the direction of the maximum outer diameter. The outer wall of the compressed area of ​​the atomizing substrate fits tightly against heating tube 1, avoiding the poor contact problem that occurs when the atomizing substrate is inserted into a circular heating tube.

[0043] Furthermore, in this embodiment, the radial cross-sectional area of ​​the elliptical cylindrical cavity of the heating tube 1 is equal to or slightly smaller than the radial cross-sectional area of ​​the atomizing matrix. This allows the outer wall of the atomizing matrix to be in contact with the inner wall of the heating tube 1 after it is inserted into the heating tube 1 and deformed into an elliptical cylindrical structure. This maximizes the contact area between the atomizing matrix and the heating tube 1, which is beneficial for improving heating efficiency and achieving faster smoke output.

[0044] In other embodiments, the heating element 1 can also be a non-circular tube with other shapes and structures, such as Figure 3 As shown, for example, heating tube 1 is a racetrack-shaped tube. The inner diameter of heating tube 1 includes a minimum inner diameter and a maximum inner diameter. At the minimum inner diameter, the two inner walls of heating tube 1 are closer together, while at the maximum inner diameter, the two inner walls are farther apart. Specifically, the minimum inner diameter of heating tube 1 is smaller than the outer diameter of the atomizing substrate, and the maximum inner diameter of heating tube 1 is larger than the outer diameter of the atomizing substrate. This allows the atomizing substrate to compress in the direction of the minimum inner diameter and extend in the direction of the maximum outer diameter after being inserted into heating tube 1. This also ensures that the outer wall of the compressed area of ​​the atomizing substrate fits tightly against heating tube 1, avoiding the contact problems that occur when the atomizing substrate is inserted into a circular heating tube.

[0045] For example, the heating tube 1 can also be an approximately elliptical tube or an approximately racetrack-shaped tube, which can also make the outer wall of the area where the atomizing matrix is ​​compressed fit tightly with the heating tube 1, thereby improving the heating efficiency of the atomizing matrix.

[0046] In this embodiment, the heating tube 1 has a zoned heating structure, and the heating tube 1 is divided into at least two heating zones, each of which is provided with at least one heating element 2; the heating tube 1 may also be provided with four or other numbers of heating zones, and each heating zone may also be provided with multiple heating elements 2. This embodiment is described using two heating zones and one heating element 2 in each heating zone as an example.

[0047] The heating element 1 includes a first heating zone 11 and a second heating zone 12. The first heating zone 11 and the second heating zone 12 are divided along the surface where the maximum inner diameter of the heating element 1 is located, that is, along an axial surface of the heating element 1. The position where the maximum inner diameter of the heating element 1 is located is on this axial surface. A first heating element 21 is provided in the first heating zone 11, and a second heating element 22 is provided in the second heating zone 12. The first heating element 21 and the second heating element 22 can be fixed to the outer wall of the heating element 1 by means of printing, welding, etc., or the first heating element 21 and the second heating element 22 can also be fixed to the inner wall of the heating element 1 by means of printing, welding, etc., or the first heating element 21 and the second heating element 22 can also be partially or completely embedded in the heating element 1.

[0048] The first heating element 21 and the second heating element 22 can be configured as curved lines with a flat structure, which are distributed in a serpentine curve on the first heating area 11 and the second heating area 12 respectively, so as to maximize the coverage of the area of ​​the first heating area 11 and the second heating area 12, which is beneficial to improving heating efficiency.

[0049] When the atomizing substrate is inserted into the heating tube 1, the atomizing substrate deforms at the position where the heating tube 1 has the smallest inner diameter and comes into close contact with the heating tube 1. The position of this close contact corresponds to the first heating zone 11 and the second heating zone 12. That is, the first heating element 21 and the second heating element 22 are located in the region where the heating tube 1 has the smallest inner diameter. The first heating element 21 and the second heating element 22 are closer to the atomizing substrate, so that the heat generated by the first heating element 21 and the second heating element 22 can be transferred to the atomizing substrate more quickly, so as to achieve rapid heating and smoke production.

[0050] In other embodiments, the first heating element 21 and / or the second heating element 22 may also be positioned close to the area of ​​the heating tube 1 with the smallest inner diameter, which can bring the first heating element 21 and the second heating element 22 closer to the atomizing matrix and also accelerate the smoke output speed.

[0051] In this embodiment, since the heating tube 1 is an irregularly shaped tube, preferably an elliptical tube, the minimum inner diameter of the heating tube 1 is smaller than the outer diameter of the atomizing matrix, and the heating element 2 is located in or near the area of ​​the heating tube 1 with the minimum inner diameter; when the atomizing matrix is ​​inserted into the heating tube 1, the heating tube 1 will compress and deform the atomizing matrix, the circumferential outer wall of the atomizing matrix will contact the inner wall of the heating tube 1, and the heating element 2 will be closer to the atomizing matrix. This arrangement can greatly improve the heating efficiency of the atomizing matrix, increase the smoke output speed of the atomizing matrix, and ultimately improve the smoking experience.

[0052] Please refer to Figure 4In one embodiment, the heating element 1 is further provided with a heat insulation structure 13. At least one of the two connection points of the first heating area 11 and the second heating area 12 of the heating element 1 is provided with a heat insulation structure 13. Preferably, both connection points of the first heating area 11 and the second heating area 12 are provided with a heat insulation structure 13 to block the heat transfer between the two connection points of the first heating area 11 and the second heating area 12, so that when one heating area is heated, the heat is not transferred to the other area.

[0053] A heat insulation structure 13 is provided at one of the two connection points of the first heating zone 11 and the second heating zone 12, which can also play a certain role in heat insulation.

[0054] The heat insulation structure 13 can be slots distributed along the axial direction of the heating tube 1. The slots include, but are not limited to, grooves, through holes penetrating the heating tube 1, etc. The grooves can be located on the outer wall of the heating tube 1 or on the inner wall of the heating tube 1. The slots can be distributed in a straight line, and the length of the slots can be greater than half or even two-thirds of the axial length of the heating tube 1. The longer the slots are, the better they can separate the first heating zone 11 and the second heating zone 12, resulting in a better heat insulation effect.

[0055] The heat insulation structure 13 can also have other structures or shapes. For example, the heat insulation structure 13 can also include multiple holes distributed along a straight line, or the heat insulation structure 13 can be slots extending along curves, waves, or zigzag lines. The heat insulation structure 13 can also be a heat insulation material disposed between the first heating zone 11 and the second heating zone 12. In this structure, the first heating zone 11 and the second heating zone 12 are arc-shaped structures, and the heat insulation structure 13 is a strip structure. The strip structure is directly embedded between the first heating zone 11 and the second heating zone 12 and is integrally formed.

[0056] Please refer to Figure 5 In one embodiment, the slots may be filled with a heat-insulating medium 14, which is a low thermal conductivity material and may include, but is not limited to, asbestos, ceramic fiber, etc. Filling the slots of the heat-insulating structure 13 with the heat-insulating medium 14 can further improve the heat insulation effect of the heat-insulating structure 13.

[0057] In one embodiment, a heating component is provided, which can form a relatively complete heating cavity for inserting an atomizing matrix. This heating component is used to install within an aerosol generating device, serving as the main working area within the device.

[0058] Please refer to Figure 6The heating component 100 in this embodiment includes the heating element 10 in any of the above embodiments. The heating component 100 also includes an upper cover 20 and a lower cover 30, which are respectively installed on the upper and lower ends of the heating element 10. The upper cover 20, the heating element 10, and the lower cover 30 are connected in sequence to form a complete heating cavity. The upper cover 20 and the lower cover 30 also serve to fix the heating element 10 within the aerosol generating device.

[0059] The upper cover 20 and the lower cover 30 are made of low thermal conductivity and high temperature resistant materials, including but not limited to PEEK and PI. The upper cover 20 and the lower cover 30 can block the heat generated by the heating element 10 from escaping, providing a certain degree of heat preservation. At the same time, they can prevent the heat from the heating element 10 from escaping to the housing, battery, circuit board, and other components of the aerosol generating device. Preventing heat from escaping to the housing does not affect the user's grip, and preventing heat from escaping to the battery, circuit board, and other components ensures the normal operation of other components inside the aerosol generating device.

[0060] The upper cover 20 has an insertion port 201 and an upper locking part 202, which can be a slot or similar structure. One end (upper end) of the heating tube 1 is connected to the upper locking part 202. The heating tube 1 is inserted into the upper locking part 202 of the upper cover 20 from bottom to top, and the upper cover 20 limits the upward movement of the heating tube 1. The insertion port 201 of the upper cover 20 is axially aligned and connected with the cavity inside the heating tube 1, and the atomizing matrix can be inserted into the heating tube 1 through the insertion port 201 for heating.

[0061] The lower cover 30 is an inverted cap-like structure. The lower cover 30 has a lower locking part 301, which can also be a slot or other structure. The other end (lower end) of the heating tube 1 is connected to the lower locking part 301. The heating tube 1 is inserted from top to bottom into the lower locking part 301 of the upper cover 20. The lower cover 30 limits the downward movement freedom of the heating tube 1. Simultaneously, the lower cover 30 seals the opening at the lower end of the heating tube 1. The lower cover 30 not only limits the heating tube 1 but also limits the insertion of the atomizing substrate. After the atomizing substrate is inserted into the heating tube 1, further insertion will bring it into contact with the lower cover 30, which limits the maximum insertion depth of the atomizing substrate. The lower cover 30 also serves a positioning function, positioning the tobacco segment of the atomizing substrate that needs to be heated into the heating tube 1, preventing misalignment issues such as the tobacco segment not being inserted correctly or being inserted too far.

[0062] In this embodiment, the heating element 1 is a shaped tube, preferably an elliptical tube, with a minimum inner diameter smaller than the outer diameter of the atomizing matrix. The heating element 2 is located in or near the area of ​​the heating element 1 with the minimum inner diameter. When the atomizing matrix is ​​inserted into the heating element 1, the heating element 1 will compress and deform the atomizing matrix. The circumferential outer wall of the atomizing matrix will contact the inner wall of the heating element 1, and the heating element 2 will be closer to the atomizing matrix. This arrangement can greatly improve the heating efficiency of the atomizing matrix, increase the smoke output speed of the atomizing matrix, and ultimately improve the smoking experience.

[0063] Please refer to Figure 7 In one embodiment, the heating element 100 further includes an outer sleeve 40, which is connected between the upper cover 20 and the lower cover 30. The outer sleeve 40 is located circumferentially outside the heating tube 1, and a heat insulation cavity is formed between the outer sleeve 40 and the heating tube 1. The heat insulation cavity can be filled with a heat insulation medium such as air. Air has the characteristic of slow thermal conductivity, which can reduce the heat loss from the heating tube 1. The heat insulation cavity can also be filled with other heat insulation media with low thermal conductivity, such as heat insulation cotton.

[0064] The outer sleeve 40 can be made of the same or similar low thermal conductivity, high temperature resistant material as the upper cover 20 and the lower cover 30, including but not limited to PEEK, PI, etc. The outer sleeve 40 can also be an integral structure with one or both of the upper cover 20 and the lower cover 30. An integrated structure reduces the number of parts, facilitates installation, and also reduces connection gaps, resulting in better insulation.

[0065] Please refer to Figure 8 In one embodiment, a heat insulation pipe 50 is also installed in the heating cavity between the outer sleeve 40 and the heating tube 1. The heat insulation pipe 50 can be a heat-absorbing structure such as metal. The heat insulation pipe 50 can absorb the heat in the air in the heating cavity and form a heat insulation layer to keep the heating tube 1 warm.

[0066] In one embodiment, an aerosol generating device is provided, which includes the heating component 100 of any of the above embodiments.

[0067] Please refer to Figure 9 The aerosol generating device also includes a housing 200, a battery 300, and a circuit board 400, with the heating element 100, battery 300, and circuit board 400 installed inside the housing 200.

[0068] The housing 200 is provided with an inlet, the heating element 100 is located near the inlet of the housing 200, and the inlet of the housing 200 is axially aligned with and connected to the heating tube 1 of the heating element 100, so that the atomizing matrix can be inserted into the heating tube 1 through the inlet of the housing 200.

[0069] The circuit board 400 is electrically connected to the battery 300 and the heating element 2, respectively. The battery 300 provides power for the operation of the circuit board 400 and the heating element 2. The circuit board 400 is used to control the heating power and heating time of the heating element 2. The circuit board 400 is also used to control multiple heating elements 2 to heat synchronously or asynchronously.

[0070] The outer casing 200 may also be equipped with a bottom cover, a charging port, and other structures to facilitate the disassembly, assembly, and charging of the aerosol generating device.

[0071] In this embodiment of the aerosol generating device, the heating tube 1 is an irregularly shaped tube, preferably an elliptical tube. The minimum inner diameter of the heating tube 1 is smaller than the outer diameter of the atomizing matrix, and the heating element 2 is located in or near the area of ​​the heating tube 1 with the minimum inner diameter. When the atomizing matrix is ​​inserted into the heating tube 1, the heating tube 1 will compress and deform the atomizing matrix. The circumferential outer wall of the atomizing matrix will contact the inner wall of the heating tube 1, and the heating element 2 will be closer to the atomizing matrix. This arrangement can greatly improve the heating efficiency of the atomizing matrix, increase the smoke output speed of the atomizing matrix, and ultimately improve the smoking experience.

[0072] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
