[0037] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of the present disclosure can be combined with each other, and the detailed description in the specific implementation methods should be understood as an explanation of the purpose of the present disclosure and should not be regarded as an improper limitation on the present disclosure.

[0038] In the description of the embodiments of the present disclosure, it should be noted that the terms "upper," "lower," "top," and "bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in FIG2 . These orientation terms are intended solely to facilitate the description of the embodiments of the present disclosure and to simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the embodiments of the present disclosure. The present disclosure will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] One aspect of the present disclosure provides an aerosol generating system, comprising an aerosol generating article 200 and an aerosol generating device according to any of the above embodiments. The heating element 32 of the aerosol generating device has a heating space, and the aerosol generating article 200 is at least partially disposed in the heating space.

[0040] The aerosol-generating article 200 is disposed in the heating space, and the heating element is used to heat the aerosol-generating article 200 to generate aerosol.

[0041] It should be noted that, in the embodiment of the present disclosure, referring to FIG. 3 , the aerosol generating article 200 is in a solid form.

[0042] The type of aerosol generating article 200 is not limited. For example, an aerosol generating article 200 without paper or aluminum foil wrapping may be used.

[0043] The structure of the aerosol-generating article 200 is not limited. For example, in some embodiments, the aerosol-generating article 200 may include a functional segment and an aerosol-generating substrate, with the functional segment disposed at one end of the aerosol-generating substrate along its length. It should be noted that the aerosol-generating article 200 relies on the aerosol-generating substrate to generate aerosol, and the functional segment does not generate aerosol.

[0044] The functional section may include a cooling section for cooling the aerosol to reduce its temperature and alleviate the "burning mouth" phenomenon when the user inhales the aerosol. The functional section may also include a support section, which has a certain structural strength and serves to limit the axial position of the aerosol-generating matrix. The functional section may also include a filtering section for filtering the aerosol.

[0045] In other embodiments, the aerosol-generating article 200 does not include a functional segment.

[0046] The aerosol-generating article 200 may further include an outer wrapping layer that wraps around the functional segment and the outer periphery of the aerosol-generating substrate. Alternatively, the aerosol-generating article 200 may be devoid of an outer wrapping layer. Specifically, in the embodiments of the present disclosure, an aerosol-generating article 200 without an outer wrapping layer is used as an example.

[0047] The material of the aerosol-generating substrate is not limited. For example, aerosol-generating articles 200 include, but are not limited to, pharmaceuticals, nicotine-containing materials, or nicotine-free materials. In one example, the aerosol-generating substrate is provided with macroscopic internal airflow channels. The aerosol-generating substrate can be manufactured by extrusion, die-casting, or other methods, and the internal airflow channels can be directly formed by extrusion, die-casting, or other methods. Of course, the aerosol-generating substrate can also have microscopic vents, which are not limited here.

[0048] The shape of the aerosol-generating article 200 is not limited. For example, the cross-section of the aerosol-generating article 200 on a plane perpendicular to its axial direction can be one of circular, polygonal, elliptical, and racetrack-shaped.

[0049] Among them, the runway shape refers to a shape similar to an athletic track, which is composed of two semicircles and two parallel straight sides alternately connected.

[0050] Illustratively, the heating assembly 30 further has an opening communicating with the heating space, and the aerosol-generating article 200 can enter the heating space through the opening.

[0051] The shape and size of the heating space are not limited. For example, the size of the heating space is designed to be slightly larger than the size of the aerosol-generating article 200. This allows a gap to be formed between the aerosol-generating article 200 and the sidewall of the heating space. Airflow reaching the opening can pass through this gap to the side of the heating space facing away from the opening, and then flow through the interior of the aerosol-generating article 200, thereby carrying away the aerosol generated by the atomization of the aerosol-generating article 200 for inhalation by the user.

[0052] One aspect of an embodiment of the present disclosure provides an aerosol generating device, as shown in FIG. 1 to FIG. 2 , which includes a power supply assembly and an aerosol generating device 100 provided by any embodiment of the present disclosure.

[0053] The power supply device is primarily used to power the aerosol generating device 100 and control operations such as turning the entire aerosol generating device on and off. The aerosol generating device 100 is primarily used to house an aerosol generating product 200 and, when powered on, heat and atomize the aerosol generating product 200. The aerosol generating product 200 includes, but is not limited to, materials used for medical treatment, health preservation, wellness, and beauty purposes.

[0054] In some embodiments, the aerosol generating device 100 and the power supply device can be mechanically and electrically connected together along the axial direction (i.e., the height direction). Furthermore, the aerosol generating device 100 and the power supply device can be connected together in a detachable manner such as a magnetic connection, a threaded connection, or a snap connection. The aerosol generating device 100 and the power supply device can both be replaced or upgraded separately, reducing replacement costs and saving users money. Of course, in other embodiments, the aerosol generating device 100 and the power supply device can also be connected together in a non-detachable manner.

[0055] In addition, the aerosol generating device 100 and / or the power supply device are not limited to being cylindrical, and may also be in other shapes such as an elliptical column or a square column.

[0056] It should be noted that the specific type of the aerosol generating device provided in the embodiments of the present disclosure is not limited. For example, the aerosol generating device can be a medical atomization device, an air humidifier, or an atomization device such as an electronic cigarette.

[0057] Another aspect of the present disclosure provides an aerosol-generating device 100, as shown in Figures 1 to 5 , comprising a mounting bracket 20 and a heating assembly 30. The mounting bracket 20 defines a mounting space. The heating assembly 30 includes a connector and a heating element 32 secured to the connector. The connector is connected to the mounting bracket 20. The heating element 32 is located within the mounting space and is configured to heat the atomized aerosol-generating article 200 to generate an aerosol.

[0058] Exemplarily, the aerosol generating device 100 further includes a housing 10 having a receiving space 10 a .

[0059] The housing 10 and the mounting bracket 20 can be understood as the main body 311 of the aerosol generating device, and the housing 10 and the mounting bracket 20 constitute the general framework of the aerosol generating device.

[0060] At least a portion of the housing 10 may serve as the exterior appearance of the aerosol generating device, and the accommodating space 10 a may facilitate the installation of the bracket 20 and the heating assembly 30 .

[0061] The type of the heating element is not limited. For example, the heating element is a heating tube, and the internal space of the heating tube is the heating space.

[0062] The material of the heating tube is not limited. For example, it can be stainless steel or quartz. The heating tube is used to heat the aerosol-generating article 200 and generate aerosol. In other words, the aerosol-generating article 200 of the present embodiment is heated circumferentially.

[0063] The heating technology of the heating tube is not limited, and can be, for example, electromagnetic induction heating or resistance film heating.

[0064] In the aerosol generating device provided in the embodiment of the present disclosure, the heating assembly 30 includes a connector and a heating element 32 fixed to the connector. The mounting bracket 20 has an installation space, and the heating element 32 is located within the installation space. The heating assembly 30 is fixed by directly connecting the connector to the mounting bracket 20. In the related art, the heating assembly 30 is fixed by providing connectors to clamp at both ends of the heating element 32, and by providing a fixing bracket around the outer periphery of the heating element 32 to fix the connectors at both ends of the heating element 32. However, the aerosol generating device 100 in the embodiment of the present disclosure can choose not to provide a fixing bracket to fix the connector, but instead directly connect the connector to the mounting bracket 20 to fix the heating assembly 30. This is conducive to miniaturization of the aerosol generating device 100, saving parts, reducing costs, improving assembly efficiency, and enhancing user experience. In addition, since no additional fixing bracket is provided to fix the heating component 30, it is helpful to reduce the heat generated by the heating component 30 and transferred to the fixing bracket, so that the heat can be kept in the heating component 30 as much as possible, reducing energy consumption during heating and improving heating performance.

[0065] It should be noted that the specific structure of the connecting member is not limited here, as long as it can be connected to the mounting bracket 20 and fix the heating element 32 in the installation space.

[0066] In some embodiments, referring to Figures 2 to 5 , the connector includes at least two connecting brackets 31. The two connecting brackets 31 are disposed at both ends of the heating element 32 in the height direction and are respectively connected to the mounting bracket 20. The connecting bracket 31 includes a main body 311 and a first mounting portion 312. The main body 311 is used to fix the heating element 32. One end of the first mounting portion 312 is connected to the main body 311, and the other end extends away from the main body 311. The first mounting portion 312 is provided with a connecting structure 312a, which is connected to the mounting bracket 20.

[0067] That is, by providing two connecting brackets 31, each disposed at either end of the heating element 32 in the height direction, the heating element 32 is secured, and the two connecting brackets 31 are each connected to the mounting bracket 20 to secure the heating assembly 30. This connection structure 312a is simple and reliable, and does not require additional components for securing the connecting brackets 31. This facilitates miniaturization of the aerosol generating device 100, saves components, reduces costs, and enhances the user experience.

[0068] The specific structure of the connecting bracket 31 is not limited here. For example, please refer to Figures 3 to 5. The connecting bracket 31 includes a main body 311 and a first mounting portion 312. The main body 311 is used to fix the heating element 32, and the first mounting portion 312 is used to connect to the mounting bracket 20.

[0069] 3 to 5 , in a cross section perpendicular to the extension direction of the first mounting portion 312 , the cross-sectional area of ​​at least a portion of the region between the connecting structure 312 a and the main body 311 is smaller than the cross-sectional area of ​​the edge of the connecting structure 312 a .

[0070] It can be understood that the main body 311 is used to fix the heating element 32. The heat generated by the heating element 32 will be transferred to the main body 311, and the heat on the main body 311 will be transferred to the mounting bracket 20 through the connecting structure 312a of the first mounting part 312. Therefore, by minimizing the channel area for the heat from the heating element to be transferred to the mounting bracket 20, it is beneficial to reduce the heat generated by the heating component 30 and transferred to the mounting bracket 20, so that the heat can be kept in the heating component 30 as much as possible, thereby reducing energy consumption during heating and improving heating performance.

[0071] By making the cross-sectional area of ​​at least a portion of the area between the connection structure 312a and the main body 311 smaller than the cross-sectional area of ​​the edge of the connection structure 312a, the channel area for heat transfer from the heating element to the mounting bracket 20 is reduced.

[0072] It should be noted that there are many specific ways in which the cross-sectional area of ​​at least a portion of the area between the connecting structure 312a and the main body 311 is smaller than the cross-sectional area of ​​the edge of the connecting structure 312a. For example, in some embodiments, please refer to Figure 4, a through hole 312b and / or a groove 312c is provided between the connecting structure 312a and the main body 311.

[0073] The provision of a through hole 312b and / or a groove 312c between the connection structure 312a and the main body 311 means that the connection structure 312a and the main body 311 may be provided with a through hole 312b, a groove 312c, or both a through hole 312b and a groove 312c.

[0074] It should be noted that when the connection structure 312a is a fastening hole, that is, the first mounting portion 312 and the mounting bracket 20 are fastened together, the edge of the connection structure 312a does not pass through the fastening hole.

[0075] That is to say, by setting a through hole 312b and / or a groove 312c between the connecting structure 312a and the main body 311, the cross-sectional area of ​​at least part of the area between the connecting structure 312a and the main body 311 can be smaller than the cross-sectional area of ​​the edge of the connecting structure 312a, thereby reducing the channel area for heat transfer from the heating element to the mounting bracket 20.

[0076] In other embodiments, referring to FIG. 3 , the through hole 312b and / or the groove 312c may not be provided, and the cross-sectional area of ​​the first mounting portion 312 near one end of the main body 311 may be reduced so that the cross-sectional area of ​​at least a portion of the area between the connecting structure 312a and the main body 311 is smaller than the cross-sectional area of ​​the edge of the connecting structure 312a.

[0077] In some embodiments, referring to FIG3 , the aerosol generating device 100 further includes a housing 10 having a receiving space 10a. The connecting bracket 31 further includes a second mounting portion 313 disposed on a side of the main body 311 facing away from the first mounting portion 312 and connected to the housing 10.

[0078] The specific connection method between the second mounting portion 313 and the housing 10 is not limited here. For example, the second mounting portion 313 and the housing 10 can be connected by magnetic connection, snap connection, fastening connection or plug connection.

[0079] The fastening connection includes but is not limited to screw connection, bolt connection or rivet connection, etc.

[0080] Thus, by providing the second mounting portion 313 on the side of the main body 311 away from the first mounting portion 312 , the second mounting portion 313 is connected to the housing 10 , thereby improving the reliability of the connection between the connector and the housing 10 and / or the mounting bracket 20 .

[0081] In some embodiments, referring to Figures 2 and 3 , the heating assembly 30 further includes a sealing member 33. The main body 311 defines a receiving cavity 311a, into which at least a portion of the heating element 32 is inserted. The sealing member 33 seals at least between the cavity wall of the receiving cavity 311a and the outer wall of the heating element 32.

[0082] It should be noted that the accommodating cavity 311 a inside the main body 311 may be an accommodating channel running through the main body 311 , or may be an accommodating groove with an opening at one end.

[0083] The seal 33 is at least partially sandwiched between the wall of the accommodating chamber 311a and the outer wall of the heating element 32. In other words, the seal 33 is used to seal at least the installation gap between the wall of the accommodating chamber 311a and the outer wall of the heating element 32. This improves the seal between the main body 311 and the heating element 32, preventing aerosol or condensed aerosol from flowing into the installation gap to a certain extent, thereby enhancing the user experience. Furthermore, the provision of the seal 33 helps to improve the reliability of the connection structure 312a between the connector and the heating element 32.

[0084] The sealing member 33 is at least sealingly clamped between the cavity wall of the accommodating cavity 311a and the outer wall of the heating member 32. For example, in addition to being sealingly clamped between the cavity wall of the accommodating cavity 311a and the outer wall of the heating member 32, the sealing member 33 can also be sealingly clamped between the end of the main body 311 and the thermal insulation member of the aerosol generating device 100, thereby further improving the sealing between the main body 311 and the thermal insulation member.

[0085] Specifically, the sealing member 33 includes a sealing body and a flange formed on the peripheral side wall of the sealing body. The sealing body is sleeved on the heating member 32, and the sealing clamp is arranged between the cavity wall of the accommodating cavity 311a and the outer wall of the heating member 32. The flange sealing clamp is arranged between the end of the main body 311 and the thermal insulation member of the aerosol generating device 100.

[0086] Exemplarily, one of the sealing member 33 and the cavity wall of the accommodating cavity 311 a is provided with a buckle, and the other one is provided with a slot. The sealing member 33 and the main body 311 are connected by the buckle and the slot.

[0087] The specific material of the sealing member 33 is not limited here. Since the sealing member 33 is at least sealingly sandwiched between the cavity wall of the accommodating cavity 311 a and the outer wall of the heating member 32 , the sealing member 33 needs to have a certain high temperature resistance.

[0088] In some embodiments, referring to Figures 3 to 5, the connecting bracket 31 arranged on the top of the heating element 32 is the first connecting unit 31a, and the connecting bracket 31 arranged on the bottom of the heating element 32 is the second connecting unit 31b. The first connecting unit 31a has an accommodating channel that penetrates the first connecting unit 31a along the height direction, and the second connecting unit 31b has an accommodating groove. One end of the heating element 32 is inserted into the accommodating channel, and the other end of the heating element 32 is inserted into the accommodating groove.

[0089] For the convenience of description, the connection bracket 31 disposed on the top of the heating member 32 is named as a first connection unit 31 a , and the connection bracket 31 disposed on the bottom of the heating member 32 is named as a second connection unit 31 b .

[0090] The first connecting unit 31a has a receiving channel extending vertically through the first connecting unit 31a. The second connecting unit 31b has a receiving slot. One end of the heating element 32 is inserted into the receiving channel, while the other end of the heating element 32 is inserted into the receiving slot. In this manner, the heating element 32 is secured, and the aerosol-generating article 200 can be inserted into the heating space through the receiving channel.

[0091] Illustratively, a sealing member 33 may be provided between the side wall of the accommodating channel and the outer side wall of the heating member 32 , and a sealing member 33 may also be provided between the groove wall of the accommodating groove and the outer side wall of the heating member 32 .

[0092] The installation and positioning method of the heating element 32 in the accommodating channel and the accommodating groove is not limited.

[0093] In some embodiments, referring to Figures 3 to 5 , a first positioning surface 311b is formed on the sidewall of the receiving channel. A second positioning surface 311c is formed on the bottom or sidewall of the receiving groove. Two connecting brackets 31 are respectively connected to the mounting bracket 20, and the opposite ends of the heating element 32 are clamped between the first positioning surface 311b and the second positioning surface 311c.

[0094] The second positioning surface 311c is formed on the bottom or side wall of the accommodating groove, which means that the second positioning surface 311c can be formed on the bottom of the accommodating groove, or on the side wall of the accommodating groove, or the second positioning surface 311c can be formed on both the bottom and the side wall of the accommodating groove.

[0095] In this embodiment, the opposite ends of the heating element 32 are inserted into the first connecting unit 31a and the second connecting unit 31b, respectively, and then the first connecting unit 31a and the second connecting unit 31b are respectively connected to the mounting bracket 20, thereby clamping the opposite ends of the heating element 32 between the first positioning surface 311b and the second positioning surface 311c. When assembly is required, the first connecting unit 31a and the second connecting unit 31b are respectively connected to the mounting bracket 20, making both disassembly and assembly relatively convenient.

[0096] In some embodiments, referring to Figures 2 to 5 , the first mounting portion 312 of the first connecting unit 31a extends along a first direction. The first mounting portion 312 of the second connecting unit 31b is disposed at the bottom of the main body 311 of the second connecting unit 31b and extends along a height direction, wherein the first direction intersects the height direction.

[0097] The first direction intersects the height direction, that is, the first direction is not parallel to the height direction. For example, in some embodiments, the first direction is perpendicular to the height direction. Of course, in other embodiments, the first direction is oblique to the height direction.

[0098] By arranging the first mounting portions 312 of the first connecting unit 31a and the second connecting unit 31b in different directions, a stable triangular connecting structure 312a is formed, thereby ensuring the stable assembly of the entire heating element unit.

[0099] For example, referring to Figures 3 to 5, the first mounting portions 312 of the first connecting unit 31a and the second connecting unit 31b are both fastened to the mounting bracket 20. Specifically, the first mounting portion 312 is provided with a first fastening hole, and the top and bottom of the mounting bracket 20 are both formed with second fastening holes 20a. The first connecting unit 31a is fastened to the second fastening hole 20a at the top of the mounting bracket 20 through the first fastening hole, and the second connecting unit 31b is fastened to the second fastening hole 20a at the bottom of the mounting bracket 20 through the first fastening hole.

[0100] For example, referring to Figures 2 and 3, the first mounting portion 312 of the second connecting unit 31b is further provided with a limiting protrusion 312d, and the top of the mounting bracket 20 is provided with an insertion port 20b. The limiting protrusion 312d abuts against the top wall of the mounting bracket 20 to limit the second connecting unit 31b in the height direction of the aerosol generating device 100. The connecting structure 312a of the second connecting unit 31b extends into the interior of the mounting bracket 20 through the insertion port 20b and is connected to the mounting bracket 20.

[0101] It should be noted that the top wall of the mounting bracket 20 refers to the outer wall of the mounting bracket 20 facing the top of the aerosol generating device 100 .

[0102] The first mounting portion 312 of the second connecting unit 31 b is further provided with a limiting protrusion 312 d , which cooperates with the mounting bracket 20 to limit the second connecting unit 31 b in the height direction.

[0103] The limiting protrusion 312d is provided on the first mounting portion 312 of the second connecting unit 31b to position and limit the second connecting unit 31b, thereby improving the installation efficiency and connection reliability between the second connecting unit 31b and the mounting bracket 20.

[0104] Exemplarily, the connecting member is securely connected to the mounting bracket.

[0105] The limiting protrusion 312d abuts against the top wall of the mounting bracket 20 to limit the second connecting unit 31b in the height direction of the aerosol generating device 100. At this time, the connecting structure 312a of the second connecting unit 31b extends into the interior of the mounting bracket 20 through the plug interface 20b and is firmly connected to the mounting bracket 20, further improving the connection reliability between the second connecting unit 31b and the mounting bracket 20.

[0106] Exemplarily, the first mounting portion 312 of the second connecting unit 31b is provided with third positioning surfaces on both sides along the first direction, and the third positioning surfaces cooperate with the side walls of the plug port 20b to limit the second connecting unit 31b in the first direction.

[0107] By providing third positioning surfaces on both sides of the first mounting portion 312 of the second connecting unit 31b along the first direction, which are used to cooperate with the side walls of the plug interface 20b, the second connecting unit 31b is limited in the first direction through surface-to-surface cooperation, thereby realizing the positioning and connection of the second connecting unit 31b, improving the installation accuracy of the second connecting unit 31b, and further improving the reliability of the aerosol generating device 100.

[0108] 2 and 3 , the aerosol generating device 100 further includes a heat insulating unit 40 . The heat insulating unit 40 wraps around at least a portion of the outer periphery of the heating assembly 30 .

[0109] The heat insulation unit 40 wraps around at least a portion of the outer periphery of the heating assembly 30 , which means that the heat insulation unit 40 may wrap around a portion of the outer periphery of the heating assembly 30 or may wrap around the outer periphery of the entire heating assembly 30 .

[0110] That is to say, by providing the insulation unit 40 so that the insulation unit 40 is wrapped around at least part of the periphery of the heating component 30, it is beneficial to keep the heat in the heating component 30 as much as possible, and can reduce the heat transfer from the heating component 30 to the components around the heating component 30, reduce energy consumption during heating, avoid the impact of heat on the surrounding components, and improve the heating performance.

[0111] In some embodiments, referring to FIG. 2 and FIG. 3 , a thermal insulation gap 100 a is present between the inner wall of the housing 10 and the outer wall of the thermal insulation unit 40 .

[0112] It should be noted that there may be an insulation gap 100a between part of the inner wall of the shell 10 and the outer wall of the insulation unit 40, and another part of the inner wall may be in contact with the outer wall of the insulation unit 40, or there may be an insulation gap 100a between the entire inner wall of the shell 10 and the outer wall of the insulation unit 40.

[0113] There is an insulation gap 100a between the inner wall of the shell 10 and the outer wall of the insulation unit 40, that is, there is an insulation gap 100a between the side wall of the accommodating space 10a and the outer wall of the insulation unit 40, so that there is an air layer in the gap between the inner wall of the shell 10 and the outer wall of the insulation unit 40, further improving the insulation effect.

[0114] In some embodiments, referring to Figures 2 and 3 , the thermal insulation unit 40 includes a first thermal insulation member 41 and a second thermal insulation member 42. The first thermal insulation member 41 wraps around the periphery of the heating member 32 and is located between the two connecting brackets 31. The second thermal insulation member 42 wraps around the periphery of the first thermal insulation member 41 and at least a portion of the connecting member.

[0115] By configuring the heat insulating unit 40 to include the first heat insulating member 41 and the second heat insulating member 42, the heat insulating effect can be further improved by double heat insulation.

[0116] The first thermal insulation member 41 is wrapped around the outer periphery of the heating member 32 and is located between the two connecting brackets 31. The flange sealing clamp of the sealing member 33 is arranged between the ends of the two connecting brackets 31 and the two ends of the first thermal insulation member 41 along the height direction, which can improve both the sealing performance and the thermal insulation performance.

[0117] The second thermal insulation member 42 is wrapped around the first thermal insulation member 41 and at least part of the outer periphery of the connecting member, that is, it can simultaneously isolate the heat on the heating member 32 and the connecting member, further improving the thermal insulation performance.

[0118] It should be noted that the specific type of the thermal insulation unit 40 is not limited herein. For example, in some embodiments, the thermal insulation unit 40 is aerogel, such as an organic fiber composite aerogel. Aerogel has a relatively low thermal conductivity and is not damaged by high temperatures while also having a good thermal insulation effect.

[0119] In other embodiments, the insulation unit 40 can also be ceramic fiber. Ceramic fiber insulation cotton has high temperature resistance and relatively low thermal conductivity. Ceramic fiber insulation cotton can be directly wrapped on the surface of the heating component 30 and will not be damaged by the high temperature on the surface of the heating component 30.

[0120] In some other embodiments, the thermal insulation unit 40 may also be a combination of ceramic fiber and aerogel.

[0121] In some other embodiments, the thermal insulation unit 40 is a vacuum tube.

[0122] The material of the vacuum tube is, for example, metal, ceramic or plastic.

[0123] In one specific embodiment, the sealing member 33 is first assembled into the first connecting unit 31a and the second connecting unit 31b. The ends of the heating element 32 are then inserted into the first and second connecting units 31a, 31b, respectively. The first thermal insulation member 41 is then wrapped around the outside of the heating element 32. The second thermal insulation member 42 is then wrapped around the first connecting unit 31a and part of the outer periphery of the connecting member. The assembled heating assembly 30 is then placed within the installation space defined by the mounting bracket 20 and the housing 10. The first and second connecting units 31a, 31b are then securely connected to the mounting bracket 20. This completes the assembly of the heating assembly 30.
