[0028] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0029] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various implementations, and the operational steps involved in each embodiment may be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

[0030] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0031] The heating device in this application is used to heat and atomize the aerosol generating stick to produce an aerosol for the user to inhale. The heating device can be installed in a matching atomizing device for use. The aerosol generating stick has an air inlet at one end and a suction end at the other. The aerosol generating stick contains an atomizing matrix and an atomizing channel for the circulation of gas and aerosol. When the user draws air through the suction end, the gas at the air inlet is drawn into the aerosol generating stick and flows along the atomizing channel to the suction end.

[0032] The heating device includes a heating base and a heating assembly. The heating base has a heating cavity with an open end, which is used to provide a heating space for the aerosol generating rod. The aerosol generating rod can be inserted into the heating cavity through an insertion port. The inner side wall of the heating base is provided with one or more first grooves extending in a first direction (i.e., toward the insertion port). The first grooves are connected to the insertion port. When the aerosol generating rod is inserted into the heating cavity, an airflow channel can still be formed between the first grooves and the outer side wall of the aerosol generating rod. Even if the outer side wall of the aerosol generating rod abuts against the inner side wall of the heating cavity, the airflow channel will not be blocked. The heating component is arranged on the outer wall of the heating base, and is used to heat the heating base so as to transfer heat to the heating cavity by radiating infrared rays; when the aerosol generating rod is inserted into the heating cavity for heating, the heating component directly transfers heat to the aerosol generating rod by radiating infrared rays on the one hand, and on the other hand, generates a hot air flow in the air flow channel formed by the first groove. As the user draws inspiration from the aerosol generating rod, the hot air flow extends in the first direction to flow toward the air inlet end of the aerosol generating rod and is sucked into the interior of the aerosol generating rod, and then uses the heat brought by the hot air flow to heat the interior of the aerosol generating rod.

[0033] When the aerosol generating rod is heated by the heating device in the present application, infrared ray heating and hot air flow heating can be achieved simultaneously, which can effectively increase the amount of heat received inside the aerosol generating rod, making the heating inside and outside the aerosol generating rod more uniform, which is beneficial to improving the atomization efficiency.

[0034] Some embodiments of the heating device, atomizing equipment and electronic atomizer provided by the present application are provided below in conjunction with the accompanying drawings.

[0035] In the embodiment of the first aspect of the present application, a heating device 100 is provided. Figure 1 、 Figure 2 and Figure 3As shown, the heating device 100 includes a heating base 11 and a heating component 12 provided on the outer wall of the heating base 11. The heating base 11 has a heating cavity 111 therein, and the heating cavity 111 is penetrated at one end along the first direction, and an insertion port 112 is formed at the penetration point for the aerosol generating rod 31 to be inserted into the heating cavity 111, and the other end of the heating base 11 is closed. When the heating component 12 is working, it can heat the heating base 11 to radiate infrared rays into the heating cavity 111, so that the atomizing matrix in the aerosol generating rod 31 is heated and atomized to generate an aerosol. Among them, a first groove 113 is provided on the inner wall of the heating cavity 111, and the first groove 113 extends along the first direction and is connected to the insertion port 112. When the aerosol generating rod 31 is inserted into the heating cavity 111, as shown in FIG. Figure 4 In the example, the first groove 113 will not be blocked by the aerosol generating rod 31, and an air flow channel extending along the first direction will be formed. When the heating component 12 is working, the infrared rays radiated can directly heat the aerosol generating rod 31 on the one hand, and on the other hand, can heat the air flowing through the first groove 113 to form a hot air flow. When the user performs a suction action on the aerosol generating rod 31, the air inlet end 311 of the aerosol generating rod 31 generates a negative pressure, so that the hot air flow in the air flow channel formed by the first groove 113 flows along the first direction toward the air inlet end 311 of the aerosol generating rod 31, and then is sucked into the interior of the aerosol generating rod 31 from the air inlet end 311, and the heat of the hot air flow is used to heat the interior of the aerosol generating rod 31. Through the above-mentioned setting, direct heating by infrared rays and heating by hot air flow can be formed simultaneously, the heating is more uniform, and the atomization efficiency is higher.

[0036] It should be noted that the shape and size of the first groove 113 can be set according to specific usage needs, as long as it can form an airflow channel when the aerosol generating rod 31 is inserted into the heating chamber 111. In actual use, the size of the heating chamber 111 is adapted to the aerosol generating rod 31 so that the aerosol generating rod 31 can enter the heating chamber 111; the outer wall of the aerosol generating rod 31 can contact the inner wall of the heating chamber 111, but the airflow channel formed by the first groove 113 will not be blocked. Of course, the aerosol generating rod 31 can also not contact the inner wall of the heating chamber 111. In this case, an airflow channel can be formed all around the aerosol generating rod 31.

[0037] In a further embodiment of the present application, Figure 3 and Figure 4As shown, in the first direction, the heating chamber 111 includes an insertion section 1111 and an air guide section 1112. The insertion section 1111 is located between the air guide section 1112 and the insertion opening 112, that is, the insertion opening 112 is located at the end of the insertion section 1111 away from the air guide section 1112; the insertion section 1111 is used to accommodate the aerosol generating rod 31, and the air guide section 1112 is used to guide the air flow. The air guide section 1112 is connected to the first groove 113, so that when the aerosol generating rod 31 is inserted into the insertion section 1111 of the heating chamber 111, the air guide section 1112 is opposite to the air inlet end 311 of the aerosol generating rod 31, and the hot air flow in the air flow channel formed by the first groove 113 can flow to the air guide section 1112, and then be guided to the air inlet end 311 of the aerosol generating rod 31, so as to be inhaled into the aerosol generating rod 31.

[0038] It is understood that since the airflow channel is connected to the outside world at the insertion port 112 of the heating chamber 111, if the position within the heating chamber 111 opposite the air inlet end 311 of the aerosol generating stick 31 is blocked, resulting in poor airflow, some of the hot airflow may flow in the opposite direction and out of the insertion port 112, causing heat loss and affecting the heating uniformity and efficiency of the aerosol generating stick 31. The air guide section 1112 in this embodiment can provide sufficient space for the flow of hot air, especially at the position opposite the air inlet end 311 of the aerosol generating stick 31, effectively preventing the hot airflow from being blocked and ensuring that the hot airflow can be drawn into the interior of the aerosol generating stick 31 through the air inlet end 311.

[0039] In a further embodiment of the present application, Figures 2 to 4 As shown, a first protruding structure 114 is provided in the air guiding section 1112 of the heating chamber 111, and the first protruding structure 114 extends along the first direction to the connection between the air guiding section 1112 and the insertion section 1111 to serve as a stopper. When the aerosol generating rod 31 is inserted into the heating chamber 111, the first protruding structure 114 can abut against the aerosol generating rod 31. The first protruding structure 114 plays a limiting role on the aerosol generating rod 31, and restricts the aerosol generating rod 31 in the insertion section 1111 in the first direction to prevent the aerosol generating rod 31 from entering the air guiding section 1112, so as to ensure that the air guiding section 1112 is unobstructed and prevent the air guiding section 1112 from being blocked to affect the entry of hot air flow.

[0040] It should be noted that, in practical applications, the number of the first protruding structures 114 can be one or more, and the specific position of the first protruding structures 114 is not limited to Figure 3 The position shown in the figure can be set according to the specific needs.

[0041] Furthermore, if Figures 2 to 4In the example, a plurality of first grooves 113 are circumferentially spaced apart on the inner wall of the heating chamber 111, and each first groove 113 extends along the first direction, so that when the aerosol generating rod 31 is inserted into the heating chamber 111, a plurality of air flow channels extending along the first direction can be formed on the circumference of the aerosol generating rod 31. Correspondingly, a plurality of first protruding structures 114 are provided in the air guide section 1112, each of which is located between two circumferentially adjacent first grooves 113, and each of which is connected to the inner sidewall and bottom wall of the air guide section 1112. The first protruding structures 114 extend as a whole toward the central axis of the air guide section 1112 in the first direction, so that the gap space between any two adjacent first protruding structures 114 is connected to a corresponding first groove 113. The hot air flow in each air flow channel can flow into the air guide section 1112 along the first direction during the inhalation process, and pass through the gap space between the corresponding two first protruding structures 114 to flow toward the air inlet end 311 of the aerosol generating rod 31. Specifically, the plurality of first grooves 113 are arranged at equal intervals in the circumferential direction of the heating chamber 111, and correspondingly, the plurality of first protruding structures 114 are also arranged at equal intervals in the circumferential direction of the heating chamber 111. Through the above-mentioned setting, the position of the first protrusion structure 114 can be adapted to the first groove 113 to avoid the hot air flow in the first groove 113 being blocked by the first protrusion structure 114 when entering the air guide section 1112, so that the air flow movement can be smoother; wherein, since the first protrusion structure 114 is connected to the inner side wall and the bottom wall of the air guide section 1112, when the hot air flow flows through the gap space between the first protrusion structure 114, the first protrusion structure 114 can play a guiding role, so that the movement direction of each air flow is clear and will not flow to adjacent positions, which can effectively avoid the vibration phenomenon caused by air flow turbulence, which is beneficial to improve the stability of the aerosol generating rod 31 during the suction process and improve the user experience.

[0042] In a further embodiment of the present application, Figures 3 to 5 As shown, the heating device 100 also includes a support member 13, which has an installation cavity 131 for installing the heating base 11. At least one end of the installation cavity 131 in the first direction is a through structure to allow the heating base 11 to enter the installation cavity 131; the inner side wall of the installation cavity 131 is connected to a support structure 132 for supporting the heating base 11. Correspondingly, the outer side wall of the heating base 11 at one end where the insertion port 112 is provided has a second protruding structure 115, and the second protruding structure 115 protrudes toward the outside of the heating cavity 111. The heating base 11 is arranged in the installation cavity 131 of the support member 13 along the first direction, and the second protruding structure 115 correspondingly abuts against the support structure 132 in the installation cavity 131 to support the heating base 11 through the support structure 132.

[0043] It should be noted that the second protrusion structure 115 can be a continuous structure extending circumferentially, or a circumferentially discontinuous structure, i.e., comprising multiple sub-protrusion structures spaced apart circumferentially. Accordingly, the support structure 132 can also be a continuous structure extending circumferentially, or a circumferentially discontinuous structure, i.e., comprising multiple sub-support structures spaced apart circumferentially. In actual applications, the support structure 132 can be configured according to specific needs, so that the support structure 132 and the second protrusion structure 115 abut and cooperate with each other.

[0044] Furthermore, if Figure 3 、 Figure 5 and Figure 6 As shown, the heating device 100 also includes a pressure-covering structure 14 and a contact member 15. Both ends of the pressure-covering structure 14 in the first direction are through structures, and the pressure-covering structure 14 is arranged opposite to the end face of one end of the heating base 11 where the insertion port 112 is arranged, and abuts against the heating base 11, so that the pressure-covering structure 14 is connected with the heating cavity 111 of the heating base 11, so that the aerosol generating rod 31 can pass through the pressure-covering structure 14 and be inserted into the heating cavity 111 of the heating base 11 when in use. The contact member 15 is made of a flexible material and can produce a certain elastic deformation; the contact member 15 is arranged in the pressure-covering structure 14, and the two ends of the contact member 15 in the first direction are through to form a nested form with the pressure-covering structure 14; a plurality of third protrusion structures 151 are arranged on the inner side wall of the contact member 15, and the plurality of third protrusion structures 151 are arranged at intervals along the circumferential direction. When the aerosol generating rod 31 is inserted into the heating cavity 111, as shown Figure 7 In the example shown, the aerosol generating stick 31 passes through both the gland structure 14 and the contact member 15. The multiple third protrusions 151 on the inner side of the contact member 15 abut against the outer sidewall of the aerosol generating stick 31, limiting and securing the aerosol generating stick 31. This prevents the aerosol generating stick 31 from shaking and, through contact friction, prevents axial movement of the aerosol generating stick 31. This improves the assembly stability of the aerosol generating stick 31 and avoids affecting the normal heating operation of the aerosol generating stick 31. The gaps between adjacent third protrusions 151 in the circumferential direction allow airflow to pass through, thereby forming an airflow channel within the gland structure 14 that connects the first groove 113 with the outside atmosphere.

[0045] In a further embodiment of the present application, Figure 1As shown, the heating assembly 12 includes a heating element 121 and an electrical connector 122. The heating element 121 is connected to the outer wall of the heating base 11 and extends along the circumference of the heating base 11; the connector is also provided on the outer wall of the heating base 11 and connected to the heating element 121, and the electrical connector 122 is used to connect the power supply device 22 so that the power supply device 22 supplies power to the heating element 121, causing the heating element 121 to generate heat, thereby heating the corresponding area on the heating base 11. The heating base 11 is made of a material that is transparent to infrared rays. The infrared rays generated when the heating element 121 generates heat can penetrate the heating base 11 and radiate into the heating cavity 111, so as to heat the aerosol generating rod 31 and the airflow in the heating cavity 111. There can be one or more heating elements 121, and the number of electrical connectors 122 is set according to the heating element 121.

[0046] Furthermore, the material of the heating base 11 includes but is not limited to glass and ceramics. The heating base 11 made of the above materials is suitable for infrared rays to pass through and has high thermal conductivity. It can be heated by contact with the aerosol generating rod 31, and the infrared rays can also pass through the heating base 11 to directly heat the aerosol generating rod 31.

[0047] Furthermore, if Figure 1 In the example, the heating element 121 specifically includes a first heating element 1211 and a second heating element 1212, and the electrical connector 122 specifically includes a first soldering pad 1221, a second soldering pad 1222, and a third soldering pad 1223. The first heating element 1211 and the second heating element 1212 are spaced apart along a first direction on the outer side wall of the heating base 11, and in the first direction, the first heating element 1211 is close to the insertion port 112 of the heating base 11, and the second heating element 1212 is away from the insertion port 112 of the heating base 11. The first soldering pad 1221, the second soldering pad 1222, and the third soldering pad 1223 are all arranged between the first heating element 1211 and the second heating element 1212; one end of the first heating element 1211 in the circumferential direction is connected to the first soldering pad 1221, and the other end is connected to the second soldering pad 1222; one end of the second heating element 1212 in the circumferential direction is connected to the first soldering pad 1221, and the other end is connected to the third soldering pad 1223; the first soldering pad 1221, the second soldering pad 1222, and the third soldering pad 1223 are respectively electrically connected to the power supply device 22 or the corresponding circuit, so that the first heating element 1211 and the second heating element 1212 can be connected in parallel. Specifically, the above-mentioned soldering pads and the heating elements can be connected by a conductive body such as conductive silver paste or a wire.

[0048] like Figure 1In the example, when the first solder pad 1221 and the second solder pad 1222 are simultaneously turned on, the first heating element 1211 is energized, and the first heating element 1211 generates heat independently. When the first solder pad 1221 and the third solder pad 1223 are simultaneously turned on, the second heating element 1212 is energized, and the second heating element 1212 generates heat independently. When the first solder pad 1221, the second solder pad 1222, and the third solder pad 1223 are simultaneously turned on, the first heating element 1211 and the second heating element 1212 are simultaneously energized and generate heat. The power supply device 22 or the corresponding circuit can independently control the heating temperature of the first heating element 1211 and the second heating element 1212, so as to adjust and control them according to the needs of use.

[0049] For example, in the initial stage of heating the aerosol generating rod 31, the first heating element 1211 can be controlled to be the primary heating element, i.e., the heating temperature of the first heating element 1211 is higher than the temperature of the second heating element 1212, so that the area of ​​the aerosol generating rod 31 for accommodating the atomized substrate near the suction end 312 is heated first; after the preset heating time, the second heating element 1212 can be adjusted to be the primary heating element, i.e., the temperature of the first heating element 1211 is lowered while the temperature of the second heating element 1212 is increased. At this time, the area of ​​the aerosol generating rod 31 for accommodating the atomized substrate near the air inlet end 311 is heated to prevent the area of ​​the aerosol generating rod 31 near the suction end 312 from being too high and causing a burn on the mouth. The preset time and specific heating temperature can be set according to actual usage requirements and will not be described in detail here.

[0051] Among them, because the heating base 11 of the heating device 100 is provided with a heating chamber 111 having a first groove 113, when the aerosol generating rod 31 is inserted into the heating chamber 111, not only can the infrared rays radiated from the heating component 12 to the heating chamber 111 directly heat the aerosol generating rod 31, but the air in the air flow channel formed by the first groove 113 can also form a hot air flow, and then during the inhalation process, the hot air flow is caused to flow to the air inlet end 311 of the aerosol generating rod 31 and is sucked into the interior of the aerosol generating rod 31 to heat the interior of the aerosol generating rod 31.

[0057] In addition, the electronic atomizer 300 in this embodiment also has all the beneficial effects of the heating device 100 or the atomizing device 200 in any of the above embodiments, which will not be described in detail here.

A plurality of first grooves 113 are provided on the inner side wall of the heating chamber 111. The plurality of first grooves 113 are evenly spaced in the circumferential direction of the heating chamber 111. Each first groove 113 extends along the first direction and is connected to the insertion port 112. Each first groove 113 has an arc-shaped cross-section. Figures 2 to 4 As shown, in the first direction, the heating chamber 111 includes an insertion section 1111 and an air-guiding section 1112. The insertion section 1111 is located between the air-guiding section 1112 and the insertion opening 112. The air-guiding section 1112 is located at the end of the heating chamber 111 away from the insertion opening 112. Each first groove 113 extends from the insertion opening 112 into the air-guiding section 1112 along the first direction. The insertion section 1111 is used to accommodate the aerosol generating rod 31, and the air-guiding section 1112 is used to guide the airflow.

[0062] A plurality of first protrusion structures 114 are provided in the air guide section 1112 of the heating chamber 111. The first protrusion structures 114 extend along the first direction to the connection between the air guide section 1112 and the insertion section 1111 to serve as a stopper and can abut against the air inlet end 311 of the aerosol generating rod 31. Each first protrusion structure 114 is located between two circumferentially adjacent first grooves 113, and each first protrusion structure 114 is connected to the inner side wall and the bottom wall of the air guide section 1112, and the first protrusion structure 114 as a whole extends toward the central axis of the air guide section 1112 in the first direction, so that the gap space between any two adjacent first protrusion structures 114 corresponds to a corresponding first groove 113 structure.

[0063] like Figures 3 to 5 As shown, the support member 13 has an installation cavity 131 for installing the heating base 11. Both ends of the installation cavity 131 in the first direction are through structures, and the inner wall of the installation cavity 131 is connected to a support structure 132 for supporting the heating base 11. The outer wall of the heating base 11 at one end where the insertion port 112 is provided has a second protruding structure 115, and the second protruding structure 115 protrudes toward the outside of the heating cavity 111. The heating base 11 is arranged in the installation cavity 131 of the support member 13 along the first direction, and the second protruding structure 115 correspondingly abuts against the support structure 132 in the installation cavity 131. As shown Figure 3 、 Figure 5 and Figure 6 As shown, the gland structure 14 and the contact member 15 are nested, and both ends of the gland structure 14 in the first direction are through structures. The gland structure 14 and the end face of one end of the heating base 11 where the insertion port 112 is set are opposite to each other, and abut against the end face of the heating base 11; the contact member 15 is located inside the gland structure 14, and the contact member 15 is made of a flexible material and can produce a certain elastic deformation; the two ends of the contact member 15 in the first direction are through, and a plurality of third protrusion structures 151 are set on the inner side wall of the contact member 15, and the plurality of third protrusion structures 151 are arranged at equal intervals along the circumferential direction. Figure 7 In the example, when the aerosol generating rod 31 passes through the pressure cover structure 14 and the contact member 15 and is inserted into the heating chamber 111, the multiple third protrusion structures 151 on the inner side of the contact member 15 abut against the outer side wall of the aerosol generating rod 31 to limit and fix the aerosol generating rod 31. At the same time, a gap is formed in the area between two adjacent third protrusion structures 151 for air flow to pass through, so that the insertion port 112 of the heating chamber 111 is connected to the generating rod assembly port 210 of the shell 21.

[0064] like Figure 1As shown, the heating assembly 12 includes a heating element 121 and an electrical connector 122, both of which are connected to the outer wall of the heating base 11. The heating element 121 specifically includes a first heating element 1211 and a second heating element 1212, and the electrical connector 122 specifically includes a first soldering pad 1221, a second soldering pad 1222, and a third soldering pad 1223. The first soldering pad 1221, the second soldering pad 1222, and the third soldering pad 1223 are all connected with conductive silver paste for electrical connection. The first heating element 1211 and the second heating element 1212 are spaced apart along the first direction on the outer wall of the heating base 11, and in the first direction, the first heating element 1211 is close to the insertion port 112 of the heating base 11, and the second heating element 1212 is away from the insertion port 112 of the heating base 11. The first soldering pad 1221, the second soldering pad 1222, and the third soldering pad 1223 are all arranged between the first heating element 1211 and the second heating element 1212; one end of the first heating element 1211 in the circumferential direction is connected to the first soldering pad 1221, and the other end is connected to the second soldering pad 1222; one end of the second heating element 1212 in the circumferential direction is connected to the first soldering pad 1221, and the other end is connected to the third soldering pad 1223; the first soldering pad 1221, the second soldering pad 1222, and the third soldering pad 1223 are respectively electrically connected to the power supply device 22, so that the first heating element 1211 and the second heating element 1212 can be connected in parallel. When the power supply device 22 supplies power to the first heating element 1211 and / or the second heating element 1212, the corresponding area on the heating substrate 11 can be heated.

[0065] like Figure 4 and Figure 7 As shown, one end of the aerosol generating rod 31 in the first direction is the air inlet end 311, and the other end is the suction end 312. The inside of the aerosol generating rod 31 has an atomization matrix and an atomization channel for gas and aerosol circulation; when the user performs a suction action through the suction end 312, the gas at the air inlet end 311 can be inhaled into the aerosol generating rod 31 and flow along the atomization channel to the suction end 312.

[0066] like Figures 2 to 4 as well as Figure 7As shown, when the aerosol generating rod 31 is inserted into the heating chamber 111 of the heating device 100 through the generating rod assembly port 210, in the radial direction, the outer wall of the aerosol generating rod 31 contacts the inner wall of the heating chamber 111, and at the same time, the aerosol generating rod 31 abuts against the third protruding structure 151 of the contact member 15; in the first direction, the first protruding structure 114 abuts against the air inlet end 311 of the aerosol generating rod 31, restricting the aerosol generating rod 31 in the insertion section 1111; an independent airflow channel is formed between each first groove 113 and the outer wall of the aerosol generating rod 31, one end of the airflow channel is connected to the insertion port 112 and the generating rod assembly port 210, and the other end of the airflow channel is connected to the air guide section 1112 to ensure that the air guide section 1112 is unobstructed. The air guide section 1112 is opposite the air inlet end 311 of the aerosol generating stick 31. When the heating assembly 12 is heated, it radiates infrared rays into the heating chamber. This not only directly heats the aerosol generating stick 31 with infrared radiation, but also generates a hot air flow in the airflow channel. During the user's puffing process, the hot air in the airflow channel flows into the air guide section 1112 and is directed to the air inlet end 311 of the aerosol generating stick 31. It is then drawn into the interior of the aerosol generating stick 31, thereby heating the interior of the aerosol generating stick 31. The aerosolized substrate inside the aerosol generating stick 31 is heated and atomized, generating an aerosol, which is then transported by the airflow to the inhalation end 312 for inhalation by the user.

[0067] During the heating process, corresponding heating control can be performed according to the needs of use. In the initial stage of heating the aerosol generating rod 31, the heating temperature of the first heating element 1211 and the temperature of the second heating element 1212 can be controlled. With the first heating element 1211 as the main heating element, the area of ​​the aerosol generating rod 31 for accommodating the atomized matrix near the suction end 312 is first heated; after a preset time, the temperature of the first heating element 1211 is lowered, and the temperature of the second heating element 1212 is increased at the same time, and the second heating element 1212 is adjusted to be the main heating element. At this time, the area of ​​the aerosol generating rod 31 for accommodating the atomized matrix near the air inlet end 311 is mainly heated to prevent the temperature of the area near the suction end 312 on the aerosol generating rod 31 from being too high, causing a burn to the mouth.

[0068] When the aerosol generating rod 31 is heated by the heating device 100 in the present application, infrared ray heating and hot air flow heating can be achieved simultaneously, which can effectively increase the amount of heat received inside the aerosol generating rod 31, making the heating inside and outside the aerosol generating rod 31 more uniform, which is beneficial to improving the atomization efficiency. At the same time, the use of a differentiated heating control strategy in stages can effectively prevent the mouth from being burned, which is beneficial to improving the user experience.

Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
