Description

Technical Field

[0001] This application relates to the field of aerosol atomization technology, specifically to a heating element assembly and atomizing device. Background Technology

[0002] Heat-not-burning (HNB) electronic atomization devices are used to heat aerosol products to generate aerosols. In existing technology, HNB electronic atomization devices heat aerosol products using a high-temperature hot airflow. When an aerosol product is inserted into the HNB electronic atomization device, the heating element heats the airflow flowing into the aerosol product to heat and atomize it. Because the heating efficiency of a single hot airflow on an aerosol product is relatively low, the heating time is long, thus affecting the user experience. Utility Model Content

[0003] This application provides a heating element assembly and an atomizing device, aiming to solve the technical problem of low heating and atomization efficiency of existing HNB electronic atomizing equipment for aerosol products.

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

The heated heat conductor is used to heat the side of the aerosol product. At least one of the heating element and the heated heat conductor is disposed on the path of the air intake channel to heat the airflow in the air intake channel.

[0007] In some embodiments, the heating component includes a first heating element and a first fixing element;

[0008] The air intake channel is located on the outer side wall of the heat conductor. The heat conductor has an opening opposite to the opening. The first heating element is annularly sleeved inside the heat conductor and located at the opening. The first fixing member is installed inside the heat conductor to fix the first heating element.

[0009] In some embodiments, the heating element assembly further includes a housing assembly;

[0010] The housing assembly has a mounting cavity and an air inlet communicating with the air inlet channel. The heat conductor is installed in the mounting cavity and connected to the housing assembly. The air inlet channel is formed between the housing assembly and the outer sidewall of the heat conductor, and the air inlet channel extends to the opening so that the external airflow passes through the air inlet and flows into the opening through the air inlet channel.

[0011] In some embodiments, the first fastener is cylindrical in shape and is made of a thermally conductive material;

[0012] The first heating element is pressed against the heat conductor by the first fixing member. The first fixing member is provided with multiple airflow channels along the axial direction. The multiple airflow channels are connected between the bottom of the aerosol product and the air inlet channel. The first heating element transfers heat to the first fixing member to heat the airflow in the multiple airflow channels.

[0013] In some embodiments, the heating component further includes a heat insulation element;

[0014] The heat insulation component is annularly sleeved between the outer wall of the first heating element and the inner wall of the heat conductor, and the thermal conductivity of the heat insulation component is less than that of the first fixing component.

[0015] In some embodiments, the heating component includes a second heating element and a second fixing element;

[0016] The air intake channel is located on the inner side wall of the heat conductor. The heat conductor has a bottom cover that is opposite to the opening. The second heating element is disposed on the bottom cover. The second fixing member is connected to the heat conductor and fixes the second heating element on the bottom cover.

[0017] In some embodiments, raised ribs are provided on the inner sidewall of the heat conductor;

[0018] The raised ribs protrude from the inner surface of the sidewall of the heat conductor and extend axially along the opening. A plurality of the raised ribs are arranged circumferentially along the sidewall of the heat conductor. At least a portion of the raised ribs are used to contact the side of the aerosol product. The air inlet channel is formed between the inner surface of the sidewall of the heat conductor and the side of the aerosol product.

[0019] In some embodiments, the second heating element is in the shape of a sheet, and the sheet-shaped second heating element is disposed on the side of the bottom cover away from the receiving cavity. The second fixing member is disposed on the side of the second heating element away from the bottom cover to support the second heating element on the bottom cover.

[0020] In some embodiments, the heat conductor includes a first heat-conducting section and a second heat-conducting section;

[0021] The opening is located at one end of the first heat-conducting section, the other end of the first heat-conducting section is connected to the second heat-conducting section, and the heating component is connected to the other end of the second heat-conducting section;

[0022] The first heat-conducting section has a non-circular cross-sectional shape, and the cross-section is perpendicular to the axis of the opening.

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

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

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

[0026] The housing contains the heating element assembly and the power supply assembly.

[0027] According to the heating element assembly in the above embodiments, by connecting the heat conductor to the heating element, heat can be transferred to the heat conductor when the heating element is energized and heated. When the aerosol product is inserted into the receiving cavity, the sidewall of the heat conductor contacts the side of the aerosol product, allowing the heat conductor to transfer heat to the outer periphery of the aerosol product through the sidewall, thereby heating the outer periphery of the aerosol product. Simultaneously, since the heating element and the heated heat conductor are also positioned along the path of the air inlet channel, they can also heat the airflow within the air inlet channel. The heated airflow flows towards the bottom of the aerosol product, thus heating and atomizing the interior of the aerosol product in the form of a hot airflow. Unlike the atomization method using a heating column for centralized heating in the prior art, the heat generated by the hot airflow in this application is more evenly distributed, thereby reducing the problem of scorching of the aerosol product.

[0028] Therefore, this application achieves simultaneous heating of the side and interior of an aerosol product using only one heat source, which not only improves the atomization efficiency of the aerosol product but also reduces the number of heat sources required. Furthermore, the air inlet channel is located on the side wall of the heat conductor, which not only preheats the airflow within the channel, thus improving the thermal efficiency of the heating element assembly, but also shortens the path of the air inlet channel from the opening of the heat conductor to the bottom of the aerosol product, thereby reducing heat loss during heating.

[0041] 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.

[0042] 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).

[0043] This application provides an atomizing device 1, such as... Figure 1 and Figure 2 As shown, this device is used to heat and atomize a columnar aerosol product 2. The atomizing device 1 may include a heating element assembly 10, a power supply assembly 15, and a housing 16. The heating element assembly 10 and the power supply assembly 15 may be installed inside the housing 16. The power supply assembly 15 is electrically connected to the heating element assembly 10 to supply power to the heating element assembly 10, so that the heating element assembly 10 heats the aerosol product 2 and atomizes it to generate an aerosol.

[0044] The outer casing 16 can be box-shaped or cylindrical, and the heating element assembly 10 and the power supply assembly 15 can be installed in the same outer casing 16 or in different outer casings 16. The different outer casings 16 can be detachably connected by snap-fit, screw-fit, or magnetic attraction. Furthermore, the power supply assembly 15 can include a battery cell and a circuit board. The circuit board is electrically connected to both the battery cell and the heating element assembly 10, allowing the battery cell to supply power to the heating element assembly 10 via the circuit board. Electronic devices such as a controller and a microphone can be mounted on the circuit board. The controller can control the heating power of the heating element assembly 10, and the microphone can sense airflow. Depending on the different electronic functions of the atomizing device 1, this application does not impose special restrictions on the specific structure of the power supply assembly 15 and the outer casing 16.

[0045] To improve the atomization efficiency of the atomizing device 1 for the aerosol product 2, this application also provides a heating element assembly 10, such as... Figures 2 to 9 As shown, the heating element assembly 10 may include a heat conductor 11 and a heating element 12. The heat conductor 11 has a receiving cavity 110 with an opening 111 at one end, which can be used to insert the aerosol product 2. At least a portion of the sidewall of the heat conductor 11 is used to contact the side of the aerosol product 2, and the heat conductor 11 has an air inlet channel 13, which can be used to guide external airflow to the bottom of the aerosol product 2. The heating element 12 is connected to the heat conductor 11 and is used to generate heat when energized and transfer the heat to the heat conductor 11. The heated heat conductor 11 can be used to heat the side of the aerosol product 2, and at least one of the heating element 12 and the heated heat conductor 11 is disposed in the path of the air inlet channel 13 to heat the airflow in the air inlet channel 13.

[0046] This application connects the heat conductor 11 to the heating element 12, so that when the heating element 12 is energized and heats up, heat can be transferred to the heat conductor 11. When the aerosol product 2 is inserted into the receiving cavity 110, since the side wall of the heat conductor 11 is in contact with the side of the aerosol product 2, the heat conductor 11 can transfer heat to the outer peripheral side of the aerosol product 2 through the side wall, thereby heating the outer peripheral side of the aerosol product 2. At the same time, since the heating element 12 and the heated heat conductor 11 are also arranged in the path of the air inlet channel 13, the heating element 12 and the heated heat conductor 11 can also heat the airflow in the air inlet channel 13. The heated airflow flows to the bottom of the aerosol product 2, thereby heating and atomizing the interior of the aerosol product 2 in the form of hot airflow. Unlike the atomization method of centralized heating using a heating column in the prior art, the heat in this application is more evenly distributed when heated by hot airflow, thereby reducing the problem of scorching of the aerosol product 2.

[0047] Therefore, this application can achieve simultaneous heating of the side and interior of the aerosol product 2 using only one heat source. This not only improves the atomization efficiency of the aerosol product 2 but also reduces the number of heat sources required, thereby lowering product costs. Simultaneously, the air inlet channel 13 is located on the side wall of the heat conductor 11. This not only allows the airflow within the air inlet channel 13 to be preheated by the side wall of the heat conductor 11, improving the thermal efficiency of the heating element assembly 10, but also shortens the path of the air inlet channel 13 from the opening 111 of the heat conductor 11 to the bottom of the aerosol product 2, thus reducing heat loss during heating of the heating element assembly 10.

[0048] The heat conductor 11 can be made of metals with high thermal conductivity, such as copper and aluminum, or non-metals with high thermal conductivity, such as aluminum nitride. This application does not impose any special restrictions on the specific material selection for the heat conductor 11.

[0049] In some embodiments, such as Figures 2 to 5 As shown, the heating assembly 12 may include a first heating element 121 and a first fixing member 122; the air intake channel 13 may be disposed on the outer side wall of the heat conductor 11, the heat conductor 11 may have an opening 112 disposed opposite to the opening 111, the first heating element 121 may be annularly sleeved in the heat conductor 11 and located at the opening 112, and the first fixing member 122 is installed in the heat conductor 11 to fix the first heating element 121.

[0050] In this way, the heat conductor 11 forms a tubular structure with an opening 111 at one end and an open end 112 at the other end, allowing external airflow to flow from the outer sidewall of the heat conductor 11 into the open end 112, and then through the open end 112 to the bottom of the aerosol product 2. During this process, the outer sidewall of the heat conductor 11 can preheat the external airflow, and the inner sidewall of the heat conductor 11 can heat the side surface of the aerosol product 2. The preheated external airflow can also be heated by the first heating element 121 when passing through the open end 112, causing the hot airflow to flow from the bottom of the aerosol product 2 into its interior, thereby heating and atomizing the aerosol product 2. Thus, this application maximizes the use of the heat from the heat conductor 11 and the first heating element 121 to heat and atomize the aerosol product 2 with a shorter airflow path, improving the atomization efficiency of the aerosol product 2 and the heat utilization rate of the heating element assembly 10.

[0051] The air intake channel 13 on the outer sidewall of the heat conductor 11 can be arranged along the axial direction of the heat conductor 11 or spirally wound around the outer sidewall of the heat conductor 11, thereby extending the contact time between the external airflow and the sidewall of the heat conductor 11, allowing the airflow in the air intake channel 13 to be fully preheated. The first heating element 121 can be configured as a ring-shaped heating mesh, heating wire, or heating plate, etc., so that the first heating element 121 can be attached to the inner sidewall of the heat conductor 11. The material of the first heating element 121 can be a metal such as nickel or titanium. This application does not impose any special restrictions on the shape of the air intake channel 13 on the outer sidewall of the heat conductor 11 or the specific structure and material of the first heating element 121.

[0052] In some embodiments, such as Figure 3 and Figure 4 As shown, the heating element assembly 10 may further include a housing assembly 14; the housing assembly 14 has a mounting cavity and an air inlet 1420 communicating with the air inlet channel 13, the heat conductor 11 is installed in the mounting cavity and connected to the housing assembly 14, the air inlet channel 13 is formed between the housing assembly 14 and the outer side wall of the heat conductor 11, and the air inlet channel 13 extends to the opening 112 so that external airflow passes through the air inlet 1420 and flows into the opening 112 through the air inlet channel 13.

[0053] For example, the housing assembly 14 may include components such as a housing support 141, a housing cover 142, an air duct component 143, a clamping component 144, and a base 145. The base 145 is connected to the bottom of the tubular housing support 141 and together with the housing support 141, forms a mounting cavity. The heat conductor 11 is installed in the mounting cavity, and the top of the heat conductor 11 is supported on the inner side of the housing support 141. An air intake channel 13 is formed between the housing support 141 and the heat conductor 11. The housing cover 142 is connected to the top of the housing support 141 and presses the heat conductor 11 against the housing support 141. An air intake port 1420 may be provided on the side wall of the housing cover 142 and communicate with the air intake channel 13. The air duct component 143 may be installed inside the housing cover 142 to guide external airflow into the air intake port 1420. The clamping member 144 is disposed on the top of the air passage member 143, and the clamping member 144 can press the air passage member 143 into the cover 142 by assembling with the housing 16 to ensure the airtightness of the air passage member 143.

[0054] When external airflow flows into the air duct 143, it can enter the air intake channel 13 through the air inlet 1420 and eventually flow to the opening 112. Along the airflow path, the sidewall of the heat conductor 11 can preheat the airflow at the air intake channel 13, and the first heating element 121 can heat the airflow at the opening 112, thereby forming a hot airflow that heats and atomizes the aerosol product 2. The housing support 141 and the base 145 can be made of insulating material to reduce heat loss inside the heating element assembly 10, thereby improving heat utilization.

[0055] In other embodiments, the housing assembly 14 can also be configured as a structure in which the housing support 141 and the base 145 are integrally formed. The heat conductor 11 can also be installed and supported on the base 145. By opening holes at the bottom of the heat conductor 11, airflow can also be directed to the bottom of the aerosol product 2. This application does not impose any special restrictions on the specific structure of the housing assembly 14.

[0056] In some embodiments, such as Figure 3 and Figure 4 As shown, the first fixing member 122 can be cylindrical in shape, and the material of the first fixing member 122 can be a heat-conducting material; the first heating element 121 is pressed against the heat conductor 11 through the first fixing member 122, and the first fixing member 122 can be provided with multiple airflow channels 1220 along the axial direction. The multiple airflow channels 1220 are connected between the bottom of the aerosol product 2 and the air inlet channel 13. The first heating element 121 can transfer heat to the first fixing member 122 to heat the airflow in the multiple airflow channels 1220.

[0057] By setting the first fixing member 122 as a columnar structure with multiple airflow channels 1220 and setting the material of the first fixing member 122 as a heat-conducting material, the first fixing member 122 can not only fix the first heating element 121, but also fully heat the airflow flowing into the opening 112 by utilizing the multiple airflow channels 1220, so as to avoid the problem that the airflow temperature is uneven and affects the atomization effect of the aerosol product 2.

[0058] The multiple airflow channels 1220 can be arranged in a ring array or a rectangular array on the first fixing member 122. The heat-conducting material of the first fixing member 122 can be the same as that of the heat conductor 11, so that the airflow in the airflow channels 1220 can be fully heated. In other embodiments, the first fixing member 122 can also be configured as a baffle, a ring, or other structural forms. This application does not impose any special restrictions on the arrangement of the airflow channels 1220 or the specific structure and material of the first fixing member 122.

[0059] In some embodiments, such as Figure 3 and Figure 4 As shown, the heating component 12 may also include a heat insulation component 123; the heat insulation component 123 is annularly sleeved between the outer wall of the first heating component 121 and the inner wall of the heat conductor 11, and the thermal conductivity of the heat insulation component 123 is less than the thermal conductivity of the first fixing component 122.

[0060] Since the sides of the aerosol product 2 are typically wrapped with paper and glue to contain the aerosol material, excessively high temperatures in the heat conductor 11 can easily lead to the generation of impurity gases, thus affecting the user experience. By providing a heat insulation component 123 with a low thermal conductivity between the first heating element 121 and the heat conductor 11, the temperature of the sidewall of the heat conductor 11 can be effectively reduced, thereby decreasing the generation of impurity gases. The heat insulation component 123 can be made of materials such as zirconium oxide or alumina ceramic. This application does not impose any special restrictions on the specific material of the heat insulation component 123.

[0061] It should be noted that the function of the heat insulation component 123 is not to completely block the heat transferred from the first heating element 121 to the heat conductor 11, but rather to reduce the amount of heat transferred from the first heating element 121 to the heat conductor 11. If the heat conductor 11 is made of a heat-conducting material with a low thermal conductivity, it may not be necessary to separately install the heat insulation component 123, allowing the first heating element 121 to be directly attached to the inner surface of the sidewall of the heat conductor 11. This application does not impose any special restrictions on whether or not a heat insulation component 123 is installed inside the heating element assembly 10.

[0062] In some embodiments, such as Figure 5 As shown, the heat conductor 11 may include a first heat-conducting section 115 and a second heat-conducting section 116; an opening 111 is disposed at one end of the first heat-conducting section 115, and the other end of the first heat-conducting section 115 is connected to the second heat-conducting section 116; the heating element 12 is connected to the other end of the second heat-conducting section 116. The first heat-conducting section 115 has a non-circular cross-sectional shape, and its cross-section is perpendicular to the axis of the opening 111.

[0063] Because the first heat-conducting section 115 is non-circular in shape, after the aerosol product 2 is inserted into the receiving cavity 110, at least a portion of the sidewalls of the first heat-conducting section 115 can exert a squeezing effect on the aerosol product 2, thereby improving the efficiency of heat transfer from the sidewalls of the heat conductor 11 to the side of the aerosol product 2. For example, the cross-sectional shape of the first heat-conducting section 115 can be elliptical, and the sidewalls on both sides of the minor axis of the ellipse can squeeze the side of the aerosol product 2, thereby rapidly transferring heat to the aerosol product 2. In other embodiments, the cross-sectional shape of the first heat-conducting section 115 can also be waist-shaped or rectangular, etc. This application does not impose any special restrictions on the specific shape of the first heat-conducting section 115.

[0064] The cross-sectional shape of the second heat-conducting section 116 can be circular to facilitate the assembly of the first heating element 121, the first fixing element 122, and the heat insulation element 123. If the first heating element 121, the first fixing element 122, and the heat insulation element 123 are all configured as non-circular structures adapted to the shape of the first heat-conducting section 115, then the cross-sectional shape of the entire heat conductor 11 can be non-circular. This application does not impose any special restrictions on the specific shape of the heat conductor 11.

[0065] The above embodiment provides a detailed description of the heating element assembly 10 with the air intake channel 13 located on the outer side wall of the heat conductor 11. Alternatively, the air intake channel 13 of the heating element assembly 10 can also be located on the inner side wall of the heat conductor 11. In some embodiments, such as... Figures 6 to 9 As shown, the heating component 12 may include a second heating element 124 and a second fixing element 125; the air intake channel 13 may be disposed on the inner side wall of the heat conductor 11, the heat conductor 11 may have a bottom cover 113 disposed opposite to the opening 111, the second heating element 124 may be disposed on the bottom cover 113, and the second fixing element 125 is connected to the heat conductor 11 and fixes the second heating element 124 on the bottom cover 113.

[0066] In this way, the heat conductor 11 forms a cylindrical structure with an opening 111 at one end and a bottom cover 113 at the other end. External airflow can flow directly from the opening 111 along the inner sidewall of the heat conductor 11 to the bottom of the aerosol product 2. During this process, the inner sidewall of the heat conductor 11 can simultaneously preheat the external airflow and heat the side of the aerosol product 2. The preheated external airflow can also be heated by the second heating element 124 when it passes through the bottom cover 113, so that the hot airflow flows from the bottom of the aerosol product 2 into the interior of the aerosol product 2 to heat and atomize the aerosol product 2. Similarly, this application maximizes the use of the heat of the heat conductor 11 and the second heating element 124 to atomize the aerosol product 2 with a shorter air inlet path, thereby improving the atomization efficiency of the aerosol product 2 and the heat utilization rate of the heating element assembly 10.

[0067] In some embodiments, such as Figure 7 and Figure 8 As shown, a raised rib 114 is provided on the inner side of the sidewall of the heat conductor 11; the raised rib 114 protrudes from the inner surface of the sidewall of the heat conductor 11 and extends along the axial direction of the opening 111. A plurality of raised ribs 114 are arranged at intervals along the circumferential direction of the sidewall of the heat conductor 11. At least a portion of the raised ribs 114 are used to contact the side of the aerosol product 2. An air inlet channel 13 is formed between the inner surface of the sidewall of the heat conductor 11 and the side of the aerosol product 2.

[0068] When the aerosol product 2 is inserted into the receiving cavity 110 of the heat conductor 11, the protruding rib 114 protrudes from the inner surface of the side wall of the heat conductor 11, creating a gap between the aerosol product 2 and the inner surface of the side wall of the heat conductor 11. This gap forms an air inlet channel 13, allowing external airflow to flow directly to the bottom of the aerosol product 2. During atomization, the protruding rib 114 contacts the side of the aerosol product 2, allowing it to heat the side of the aerosol product 2. Simultaneously, the side wall of the heat conductor 11 can preheat the airflow in the air inlet channel 13. The preheated airflow is heated by the second heating element 124 as it flows through the bottom cover 113, and then flows into the aerosol product 2 for heating and atomization.

[0069] The raised rib 114 can extend along the axial direction of the opening 111 or be spirally wound around the inner side wall of the heat conductor 11, thereby extending the contact time between the external airflow and the side wall of the heat conductor 11, so that the airflow in the air intake channel 13 can be fully preheated. This application does not impose any special restrictions on the specific shape of the raised rib 114.

[0070] In some embodiments, such as Figure 7 and Figure 8 As shown, the second heating element 124 can be in the shape of a sheet. The sheet-shaped second heating element 124 is disposed on the side of the bottom cover 113 away from the receiving cavity 110. The second fixing member 125 is disposed on the side of the second heating element 124 away from the bottom cover 113 to support the second heating element 124 on the bottom cover 113.

[0071] By positioning the second heating element 124 on the side of the bottom cover 113 away from the receiving cavity 110, the problem of scorching at the bottom of the sol-gel product 2 due to excessively high temperature caused by the second heating element 124 can be avoided. In other embodiments, if the thermal conductivity of the heat conductor 11 is high, the heating temperature of the second heating element 124 can be reduced, thereby positioning the second heating element 124 on the side of the bottom cover 113 located within the receiving cavity 110. This application does not impose any special restrictions on the specific location of the second heating element 124.

[0072] The second heating element 124 can be configured as a sheet-like heating mesh, heating wire, or heating plate, and its material can be the same as that of the first heating element 121. The second fixing element 125 can be configured as a cover plate, bracket, or other structure, allowing the second heating element 124 to be attached to the bottom of the bottom cover 113. If the second heating element 124 is located on the side of the bottom cover 113 within the receiving cavity 110, the second fixing element 125 may not be necessary. This application does not impose any special restrictions on the specific structure of the second heating element 124 and the second fixing element 125.

[0073] In addition, such as Figure 7 and Figure 8 As shown, the heating element assembly 10 can also be installed inside the housing assembly 14. The housing assembly 14 may include components such as a housing support 141, a housing cover 142, an air duct 143, a clamping member 144, and a base 145. The base 145 is connected to the bottom of the tubular housing support 141 and together with the housing support 141, forms a mounting cavity. The heat conductor 11 is installed inside the mounting cavity, and the top of the heat conductor 11 is supported on the inner side of the housing support 141. The housing cover 142 is connected to the top of the housing support 141 and presses the heat conductor 11 against the housing support 141. Since the air inlet channel 13 is located inside the side wall of the heat conductor 11, the housing cover 142 does not need to be provided with an air inlet 1420. The air passage component 143 can be installed inside the housing cover 142. The clamping member 144 is located on the top of the air passage component 143. The clamping member 144 can press the air passage component 143 into the housing cover 142 by assembling with the housing 16 to ensure the air tightness of the air passage component 143.

[0074] In some embodiments, such as Figure 9 As shown, the heat conductor 11 may also include a first heat-conducting section 115 and a second heat-conducting section 116; an opening 111 is disposed at one end of the first heat-conducting section 115, and the other end of the first heat-conducting section 115 is connected to the second heat-conducting section 116, with the heating element 12 connected to the other end of the second heat-conducting section 116. The first heat-conducting section 115 has a non-circular cross-sectional shape, and its cross-section is perpendicular to the axis of the opening 111.

[0075] Similar to the above embodiments, by setting the shape of the first heat-conducting section 115 to be non-circular, after the aerosol product 2 is inserted into the receiving cavity 110, at least a portion of the sidewall of the first heat-conducting section 115 can exert a squeezing effect on the aerosol product 2, thereby improving the efficiency of heat transfer from the sidewall of the heat conductor 11 to the side of the aerosol product 2. The cross-sectional shape of the first heat-conducting section 115 can be set to an elliptical, waist-shaped, or rectangular shape, etc. This application does not impose any special limitations on the specific shape of the heat conductor 11.

[0076] 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.
