Description

Technical Field

[0001] This application relates to the field of aerosol generation equipment technology, specifically to a shell assembly, a heating assembly, and an aerosol generation device. Background Technology

[0002] Heat-not-burning (HNB) aerosol generating equipment heats aerosol products, keeping them below their ignition point and releasing aerosols. In existing technology, the insertion port for aerosol products in such equipment is typically circular. However, a circular insertion port presents several challenges: if the diameter is too large, the aerosol product may loosen within the port; conversely, if the diameter is too small, insertion may be difficult. Therefore, circular insertion ports require precise dimensional control. Utility Model Content

[0003] This application provides a housing assembly, a heating assembly, and an aerosol generating device, aiming to solve the technical problem that the aerosol generating device has high requirements for the size of the insertion port.

[0004] Some embodiments of this application provide a housing assembly, including:

[0005] The outer casing body is provided with an insertion channel for inserting an aerosol product, the cross-sectional shape of the insertion channel being adapted to the cross-sectional shape of the aerosol product, and the cross-section being perpendicular to the axial direction of the insertion channel; and,

[0006] A guide, at least one of which is connected to the sidewall of the insertion channel, and the guide gradually protrudes from the sidewall of the insertion channel radially to change the cross-sectional shape of the insertion channel at the guide position, wherein the aerosol product is fixed in the insertion channel by the guide.

[0007] In some embodiments, the housing assembly includes two of the guides;

[0008] The insertion channel has a circular cross-sectional shape, and the two guides are respectively disposed on two opposite side walls of the insertion channel. The aerosol product is held between the two guides within the insertion channel.

[0009] In some embodiments, the insertion channel has a first curvature along the circumference, and the guide has a second curvature along the circumference of the insertion channel, the first curvature being greater than the second curvature, and the two guides changing the cross-sectional shape of the insertion channel from circular to elliptical.

[0010] In some embodiments, the guide has an arcuate surface along the direction of insertion and withdrawal of the aerosol article.

[0011] In some embodiments, an airflow groove is also provided on the side wall of the insertion channel;

[0012] The airflow groove is arranged along the axial direction of the insertion channel, and the airflow groove is offset from the guide along the circumferential direction of the insertion channel. When the aerosol product is inserted into the insertion channel, an airflow gap is formed between the side wall of the insertion channel and the aerosol product in the airflow groove.

[0013] Some embodiments of this application also provide a heating component, including:

[0014] The housing assembly described in any of the above embodiments further includes a receiving cavity that communicates with the insertion channel;

[0015] A receiving member is installed within the receiving cavity, the receiving member having an inner cavity communicating with the insertion channel, and the aerosol product is inserted into the inner cavity; and,

[0016] A heating element is embedded in the accommodating member and surrounds the outer periphery of the inner cavity. The heating element is used to generate heat around the outer periphery of the aerosol product when energized, so as to atomize the aerosol product.

[0017] In some embodiments, the cross-sectional shape of the receiving member is adapted to the cross-sectional shape of the guide position;

[0018] The cross-sectional area of ​​the accommodating member is larger than that of the aerosol product. An airflow channel is formed between the inner sidewall of the accommodating member and the outer sidewall of the aerosol product. The airflow channel extends from the top of the accommodating member to the bottom of the aerosol product.

[0019] In some embodiments, the heating element includes a body portion and an outlet portion;

[0020] The body portion is embedded in the accommodating member and surrounds the outer periphery of the inner cavity. One end of the lead-out portion is connected to the body portion and embedded in the accommodating member. The other end of the lead-out portion extends to the outside of the accommodating member to conduct current. The body portion is used to generate heat around the outer periphery of the aerosol product when energized.

[0021] In some embodiments, the body portion includes at least one coil segment, and the lead-out portion includes at least two lead-out electrodes;

[0022] The axial direction of the coil segment is arranged along the axial direction of the receiving member, and the coil segment is spirally wrapped around the receiving member. The two lead electrodes are respectively connected to the beginning and end of the coil segment, and adjacent coil segments share one lead electrode.

[0023] Some embodiments of this application also provide an aerosol generating device, including:

[0024] The heating component described in any of the above embodiments;

[0025] A power supply component, electrically connected to the heating element, is used to supply power to the heating element; and,

[0026] The housing, the heating component and the power supply component are both installed inside the housing.

[0027] According to the housing assembly in the above embodiments, by providing a guide on the side wall of the insertion channel of the housing body, the cross-sectional shape of the insertion channel can be changed along the axial direction. Since the cross-sectional shape of the insertion channel matches the cross-sectional shape of the aerosol product, there is no obstruction when the aerosol product enters the insertion channel. As the aerosol product continues to move along the insertion channel, the guide protruding from the side wall of the insertion channel can gradually guide the cross-section of the aerosol product to narrow. Simultaneously, the aerosol product is fixed within the insertion channel by the guide to prevent it from loosening within the insertion channel. Therefore, even if the diameter of the insertion channel is larger than the diameter of the aerosol product, the aerosol product can still be fixed within the insertion channel due to the guide, thereby reducing the requirements for the insertion port size of the aerosol generation equipment.

Detailed Implementation

[0042] The present application will be further described in detail below with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated 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.

[0043] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0044] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0045] This application provides an aerosol generating device, such as... Figure 1 and Figure 2 As shown, the aerosol generating device may include a heating component 1, a power supply component 2, and a housing 3. The power supply component 2 is electrically connected to the heating component 1 to supply power to the heating component 1. Both the heating component 1 and the power supply component 2 are installed inside the housing 3. The power supply component 2 may include a circuit board 21 and a battery cell 22. The heating component 1 is electrically connected to the circuit board 21, and the circuit board 21 is electrically connected to the battery cell 22, allowing the battery cell 22 to supply power to the heating component 1 through the circuit board 21. Furthermore, the power supply component 2 may also include electronic components such as a controller, a charging interface, and a temperature sensor, all of which are electrically connected to the circuit board 21. For example, the controller can be used to control the heating power of the heating component 1, the charging interface can be used to connect an external power source to charge the battery cell 22, and the temperature sensor can be used to sense temperature changes when the user uses the aerosol generating device. Depending on the appearance design of the aerosol generating device, the housing 3 may be configured as a structure where the top cover and the body are detachably connected, or as a structure where the upper and lower housings are detachably connected. The shape of the housing 3 may be box-shaped, strip-shaped, or columnar. The housing 3 can be divided into multiple installation spaces by brackets, spacers, and other components for installing components such as the heating assembly 1 and the power supply assembly 2. A push-button switch electrically connected to the power supply assembly 2 can also be installed on the housing 3 to control the start / stop operation of the heating assembly 1. This application does not impose any special restrictions on the specific structure of the power supply assembly 2 and the housing 3.

[0046] It is understood that the aerosol generating device can be configured as a non-detachable integrated structure, i.e., the heating component 1 and the power supply component 2 are fixedly connected. Alternatively, the aerosol generating device can also be configured as a detachable split structure, i.e., the heating component 1 and the power supply component 2 are detachably connected, thereby allowing the heating component 1 to be disassembled for cleaning, or the power supply component 2 to be replaced to increase battery life. This application does not impose any special restrictions on the specific structural form of the aerosol generating device.

[0047] To reduce the requirements for the insertion port size of aerosol generation equipment, this application also provides a heating component 1, such as... Figures 3 to 8 As shown, the heating assembly 1 may include a receiving member 11, a heating element 12, and a housing assembly 13. The housing assembly 13 may include a housing body 131 and a guide 132. The housing body 131 is provided with an insertion channel 133 for inserting the aerosol product 4. The cross-sectional shape of the insertion channel 133 is adapted to the cross-sectional shape of the aerosol product 4, and the cross-section is perpendicular to the axial direction (aa axis) of the insertion channel 133. At least one guide 132 is connected to the sidewall of the insertion channel 133, and the guide 132 gradually protrudes from the sidewall of the insertion channel 133 radially, so that the cross-sectional shape of the insertion channel 133 changes at the position of the guide 132. The aerosol product 4 is fixed within the insertion channel 133 by the guide 132.

[0048] This application allows the cross-sectional shape of the insertion channel 133 to change along the axial direction (aa axis) by providing a guide 132 on the side wall of the insertion channel 133 of the housing body 131. Since the cross-sectional shape of the insertion channel 133 matches the cross-sectional shape of the aerosol product 4, there is no obstruction when the aerosol product 4 enters the insertion channel 133. As the aerosol product 4 continues to move along the insertion channel 133, the guide 132 protruding from the side wall of the insertion channel 133 gradually guides the cross-section of the aerosol product 4 to narrow. Simultaneously, the aerosol product 4 is fixed within the insertion channel 133 by the guide 132, preventing it from becoming loose within the insertion channel 133. Therefore, even if the diameter of the insertion channel 133 is larger than the diameter of the aerosol product 4, the guide 132 ensures that the aerosol product 4 remains fixed within the insertion channel 133, thereby reducing the requirements for the insertion port size of the aerosol generation equipment.

[0049] The power supply component 2 can be electrically connected to the heating element 12 so that the power supply component 2 can supply power to the heating element 12. Specifically, the heating element 12 is electrically connected to the circuit board 21 so that the battery cell 22 can supply power to the heating element 12 through the circuit board 21.

[0050] In some embodiments, such as Figures 5 to 7 As shown, the housing assembly 13 may include two guides 132; the cross-sectional shape of the insertion channel 133 is circular, and the two guides 132 are respectively disposed on two opposite side walls of the insertion channel 133, and the aerosol product 4 is held between the two guides 132 in the insertion channel 133.

[0051] Since the cross-sectional shape of the aerosol product 4 is usually circular, setting the cross-sectional shape of the insertion channel 133 to be circular facilitates the smooth insertion of the aerosol product 4. The cross-sectional area of ​​the insertion channel 133 can be slightly larger than the cross-sectional area of ​​the aerosol product 4 to reduce interference between the aerosol product 4 and the sidewalls of the insertion channel 133 when it enters the channel. However, the cross-sectional shape of the insertion channel 133 in this application is not limited to a circle; for example, the cross-sectional shape of the insertion channel 133 can also be a cross-sectional shape formed by polygonal sidewalls such as dodecagons or hexagons.

[0052] When the aerosol article 4 enters the insertion channel 133, the guides 132 located on the two opposite sidewalls of the insertion channel 133 can clamp the aerosol article 4, thereby preventing the aerosol article 4 from becoming loose within the insertion channel 133. In other embodiments, the housing assembly 13 may also include one guide 132, thereby forming a D-shaped cross-section of the insertion channel 133 at the location of the guide 132. Alternatively, the housing assembly 13 may also include three or four guides 132, thereby forming triangular or rectangular cross-sections of the insertion channel 133 at the locations of the guides 132, respectively. This application does not impose any special limitations on the number of guides 132 in the housing assembly 13 or the cross-sectional shape of the insertion channel 133 at the locations of the guides 132.

[0053] In some embodiments, such as Figure 5 and Figure 8 As shown, the circumferential curvature of the insertion channel 133 is a first curvature, and the guide 132 has a second curvature along the circumferential direction of the insertion channel 133. The first curvature is greater than the second curvature, and the two guides 132 change the cross-sectional shape of the insertion channel 133 from a circle to an ellipse.

[0054] When the first curvature of the insertion channel 133 along the circumference is greater than the second curvature of the guide 132 along the circumference of the insertion channel 133, since both guides 132 protrude from the sidewall of the insertion channel 133, the cross-sectional shape of the insertion channel 133 at the position of the guides 132 can change from a circle to an ellipse. After the aerosol product 4 is inserted, the two guides 132 can clamp the aerosol product 4 in the direction of the minor axis of the elliptical cross-section, thereby changing the cross-sectional shape of the aerosol product 4 from a circle to an ellipse under the action of the clamping force. At this time, the elliptical cross-section aerosol product 4 is not easy to rotate within the insertion channel 133, thus ensuring the stability of the aerosol product 4 during atomization.

[0055] In other embodiments, the two guides 132 may also be planar in shape along the circumference of the insertion channel 133. When the aerosol product 4 is inserted, the two guides 132 can guide the cross-sectional shape of the aerosol product 4 from a circle to an oblong shape under the clamping force, thus ensuring the stability of the aerosol product 4 during atomization. This application does not impose any special limitations on the specific shape of the guides 132.

[0056] In some embodiments, such as Figure 6 As shown, the guide 132 has an arc-shaped surface along the direction of insertion and withdrawal of the aerosol product 4 (aa axis direction).

[0057] When the aerosol product 4 is inserted or removed, the arc-shaped surface of the guide 132 can guide the aerosol product 4 to be inserted smoothly, thereby reducing the resistance during insertion. Furthermore, when the aerosol product 4 is held between the two guides 132, there is surface contact between the guides 132 and the aerosol product 4, preventing the guides 132 from causing scratches, cuts, or other damage to the surface of the aerosol product 4, thus avoiding breakage when the aerosol product 4 is removed. The guides 132 can have arc-shaped surfaces on both sides of the aerosol product 4 during insertion and removal to ensure smooth insertion and removal. In other embodiments, the guides 132 can also be configured with inclined surfaces along the insertion and removal directions of the aerosol product 4, which can also guide deformation of the cross-section of the aerosol product 4. This application does not impose any special limitations on the surface shape of the guides 132.

[0058] In some embodiments, such as Figures 4 to 8 As shown, an airflow groove 134 is also provided on the side wall of the insertion channel 133; the airflow groove 134 is arranged along the axial direction (aa axis) of the insertion channel 133, and the airflow groove 134 is offset from the guide member 132 along the circumference of the insertion channel 133. When the aerosol product 4 is inserted into the insertion channel 133, an airflow gap 135 is formed between the side wall of the insertion channel 133 and the aerosol product 4 in the airflow groove 134. Figure 11 (As shown).

[0059] For example, when the two guides 132 form an elliptical cross-section within the insertion channel 133, the two guides 132 are respectively positioned along the minor axis of the ellipse, while an airflow groove 134 can be respectively positioned along the major axis of the ellipse. The airflow groove 134 is recessed into the sidewall of the insertion channel 133. When the aerosol product 4 is inserted, the airflow groove 134 between the sidewall of the insertion channel 133 and the aerosol product 4 can form an airflow gap 135, allowing external air to flow into the heating assembly 1 from the airflow gap 135 for heating and atomization. Depending on the number of guides 132 provided within the insertion channel 133, three, four, or more airflow grooves 134 can also be provided on the sidewall of the insertion channel 133. This application does not impose any special limitation on the number of airflow grooves 134 provided on the sidewall of the insertion channel 133.

[0060] The above embodiments provide a detailed description of the specific structure of the housing assembly 13. For example... Figure 4 As shown, the heating assembly 1 also includes a receiving element 11 and a heating element 12. The following embodiments will provide a detailed description of the specific structures of the receiving element 11 and the heating element 12. For example... Figures 6 to 11 As shown, the outer shell assembly 13 is also provided with a receiving cavity 136, which is connected to the insertion channel 133; the receiving member 11 is installed in the receiving cavity 136, and the receiving member 11 is provided with an inner cavity 111 that is connected to the insertion channel 133, and the aerosol product 4 is inserted into the inner cavity 111; the heating element 12 is embedded in the receiving member 11 and surrounds the outer periphery of the inner cavity 111, and the heating element 12 is used to generate heat around the outer periphery of the aerosol product 4 when energized, so as to atomize the aerosol product 4.

[0061] For example, the housing 11 can be configured as an integrated cylindrical structure with an open top and a closed bottom, thus forming a sealed heating space. During the atomization process of the aerosol product 4, liquid or solid impurities generated by atomization can remain in the inner cavity 111 of the housing 11, preventing impurities from leaking out and contaminating other components of the aerosol generating equipment. Furthermore, when cleaning the heating assembly 1 is required, only the inner cavity 111 of the housing 11 needs to be cleaned, without needing to clean other components of the aerosol generating equipment, thereby simplifying the maintenance of the aerosol generating equipment.

[0062] The receiving component 11 can be installed in the receiving cavity 136 by means of insertion or abutment. The aerosol product 4 is inserted into the inner cavity 111 after passing through the insertion channel 133. Since the heating element 12 surrounds the outer periphery of the inner cavity 111, the heating element 12 can generate heat around the aerosol product 4, thereby uniformly and quickly atomizing the aerosol product 4 around its periphery, thus improving the atomization efficiency of the aerosol product 4. Embedding the heating element 12 in the receiving component 11 allows the receiving component 11 to wrap around the heating element 12, thereby protecting the heating element 12 from problems such as wire breakage, corrosion, and oxidation, extending the durability of the heating element 12, and improving the heating stability of the heating assembly 1. At the same time, the receiving component 11 can also fix the heating element 12 to prevent the heating element 12 from colliding with the receiving component 11 due to shaking.

[0063] In addition, such as Figure 4 and Figure 10 As shown, the heating assembly 1 may further include a vibration damper 14 and a base 15. The receiving component 11 can be inserted into the base 15, and the vibration damper 14 is connected between the receiving component 11 and the base 15. The receiving component 11 can be made of high-temperature resistant insulating materials such as silicon dioxide, zirconium oxide, or glass, and its porosity is less than 20% to prevent impurities from flowing out of the receiving component 11 after atomization of the aerosol product 4. The heating element 12 can be made of high-temperature resistant conductive materials such as nickel 50 alloy, nickel-chromium-aluminum alloy, or titanium; alternatively, the heating element 12 can be made of a material with a high temperature coefficient of resistance (TCR). The vibration damper 14 can be made of elastic materials such as silicone or rubber. The vibration damper 14 not only provides vibration damping protection for the receiving component 11 but also provides heat insulation. This application does not impose any special restrictions on the specific materials of the receiving component 11, the heating element 12, and the vibration damper 14.

[0064] In some embodiments, such as Figures 9 to 11 As shown, the cross-sectional shape of the accommodating member 11 is adapted to the cross-sectional shape of the guide member 132; the cross-sectional area of ​​the accommodating member 11 is larger than the cross-sectional area of ​​the aerosol product 4, and an airflow channel 112 is formed between the inner sidewall of the accommodating member 11 and the outer sidewall of the aerosol product 4, and the airflow channel 112 extends from the top of the accommodating member 11 to the bottom of the aerosol product 4.

[0065] For example, the cross-sectional shape of the accommodating member 11 can be set to an ellipse that matches the cross-sectional shape of the guide member 132. In other embodiments, the cross-sectional shape of the accommodating member 11 can also be set to a rectangle, a waist shape, or a triangle, etc. This application does not impose any special limitation on the specific cross-sectional shape of the accommodating member 11. When the aerosol product 4 is inserted into the inner cavity 111, the short axis direction of the inner cavity 111 can be used to clamp the aerosol product 4, while the long axis direction of the inner cavity 111 can form an airflow channel 112 between the inner cavity 111 and the aerosol product 4. The airflow channel 112 communicates with the airflow gap 135, allowing external air to flow into the inner cavity 111 and be heated to atomize the aerosol product 4. The bottom inner wall of the accommodating member 11 can be provided with a support portion 113. The aerosol product 4 is inserted into the inner cavity 111 and abuts against the support portion 113, so that external air can flow into the bottom of the aerosol product 4. In other embodiments, the aerosol article 4 can also be held in the inner cavity 111 along its short axis, allowing external air to flow into the bottom of the aerosol article 4. This application does not impose any special restrictions on whether a support portion 113 is provided inside the accommodating member 11.

[0066] During atomization, such as Figure 11 As shown, external air flows into the airflow channel 112 through the airflow gap 135. At this time, the external air is heated by the heating element 12, and simultaneously, the external air also lowers the temperature in the inner cavity 111. The temperature change in the inner cavity 111 can be used to detect the user's action of using the aerosol product 4. The heated external air continues to flow along the airflow channel 112 into the bottom of the inner cavity 111, and finally into the interior of the aerosol product 4 for further heating. Heating and atomizing the aerosol product 4 through hot airflow results in more uniform heating of the aerosol product 4.

[0067] In some embodiments, such as Figure 12 As shown, the heating element 12 may include a body portion 121 and an outlet portion 122. The body portion 121 is embedded in the accommodating member 11 and surrounds the outer periphery of the inner cavity 111. One end of the outlet portion 122 is connected to the body portion 121 and embedded in the accommodating member 11, and the other end of the outlet portion 122 extends to the outside of the accommodating member 11 to conduct current. The body portion 121 is used to generate heat around the outer periphery of the aerosol product 4 when energized.

[0068] The body portion 121 can be configured to have the same shape as the sidewall of the receiving member 11, and the body portion 121 can be embedded into the sidewall of the receiving member 11 through an insert injection molding process. Furthermore, the position of the body portion 121 within the sidewall of the receiving member 11 can be closer to the inner sidewall of the receiving member 11, allowing the heat radiated by the body portion 121 to be quickly transferred to the inner cavity 111, thereby reducing heat transfer loss and improving the atomization efficiency of the aerosol product 4. The welding point between the lead-out portion 122 and the body portion 121 is embedded within the sidewall of the receiving member 11, which can improve the corrosion resistance of the lead-out portion 122, thereby extending the service life of the heating assembly 1. The lead-out portion 122 is used for electrical connection with the circuit board 21, allowing the circuit board 21 to supply power to the body portion 121. When energized, the body portion 121 generates heat and heats the aerosol product 4. The lead-out portion 122 can be led out radially or axially along the receiving member 11. This application does not impose any special restrictions on the lead-out direction of the lead-out section 122.

[0069] In some embodiments, such as Figure 12 As shown, the main body 121 may include at least one coil segment 123, and the lead-out portion 122 may include at least two lead-out electrodes 124; the axial direction (aa axis) of the coil segment 123 is arranged along the axial direction (aa axis) of the receiving member 11, and the coil segment 123 is spirally wrapped around the receiving member 11; the two lead-out electrodes 124 are respectively connected to the beginning and end ends of the coil segment 123, and adjacent coil segments 123 share one lead-out electrode 124.

[0070] The body portion 121 is configured as a spiral coil structure, which makes the heat radiated from the body portion 121 to the inner cavity 111 more uniform, thereby enabling the aerosol product 4 to be heated more evenly and avoiding the problem of scorching caused by excessively high local temperatures. The body portion 121 may include multiple coil segments 123 to cover the heating requirements within the length range of the aerosol product 4, and different coil segments 123 can heat different parts of the aerosol product 4 with different powers, thereby improving atomization efficiency. For example, the body portion 121 may include an integrally wound spiral coil, and the lead-out portion 122 may include three lead-out electrodes 124. Two of the lead-out electrodes 124 are respectively connected to the beginning and end of the spiral coil, and the remaining lead-out electrode 124 is connected to the middle position of the spiral coil, so that the three lead-out electrodes 124 divide the spiral coil into two coil segments 123, and the two coil segments 123 share the lead-out electrode 124 in the middle position. The three lead-out electrodes 124 are electrically connected to the circuit board 21, which can reduce the number of lead-out electrodes 124 connected to the circuit board 21, thereby reducing the assembly difficulty of the heating component 1.

[0071] In other embodiments, the body portion 121 may further include a greater number of coil segments 123, and correspondingly, the lead-out portion 122 may further include a greater number of lead-out electrodes 124. The multiple coil segments 123 may also be configured as a split structure, with each coil segment 123 having a separate lead-out electrode 124 at both ends. This application does not impose any special limitations on the number of coil segments 123 and lead-out electrodes 124 of the heating element 12. The shape of the body portion 121 disposed on the receiving member 11 is not limited to a spiral coil; for example, the body portion 121 may also be configured as a serpentine coil structure, with the serpentine coil embedded within the receiving member 11 and surrounding the outer periphery of the inner cavity 111. Alternatively, the body portion 121 may also be configured as a mesh coil structure. This application does not impose any special limitations on the specific shape of the body portion 121.

[0072] The coil in coil segment 123 can be configured as a flat strip structure, which not only increases the heating area of ​​the coil but also the welding area, making it easier to weld the lead electrode 124 onto the coil. Furthermore, to heat different parts of the aerosol product 4 with different power, the coils in different coil segments 123 can have different helical pitches. For example, the coil segment 123 near the top of the receiving member 11 can have a denser coil, while the coil segment 123 near the bottom of the receiving member 11 can have a sparser coil, thereby improving the atomization efficiency of the aerosol product 4. This application does not impose any special limitations on the specific shape and density of the coils in coil segment 123.

[0073] 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 to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
