[0046] The flowcharts shown in the accompanying drawings are only examples and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0047] It should be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0048] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0049] See also Figures 1 to 4 The present application provides an aerosol generating device 100, comprising a mounting seat 1, a heating assembly 22, a circuit board 3 and a battery 4. The mounting seat 1 has a first cavity 1a and a second cavity 1b arranged in sequence along a first direction, and also has a third cavity 1c and a fourth cavity 1d arranged in sequence along the first direction, the third cavity 1c and the first cavity 1a are arranged in parallel along the second direction, the fourth cavity 1d and the second cavity 1b are arranged in parallel along the second direction, and the first direction is perpendicular to the second direction. The heating assembly 2 is arranged in the first cavity 1a, and the heating assembly 2 is provided with a heating cavity 2a, the heating cavity 2a is connected with the second cavity 1b, the heating cavity 2a is used to accommodate an aerosol generating substrate 200, and the heating assembly 2 can heat the aerosol generating substrate 200 to form an aerosol. The circuit board 3 is arranged in the third cavity 1c, and the circuit board 3 is electrically connected to the heating assembly 2. The battery 4 is arranged in the fourth cavity 1d, and the battery 4 is electrically connected to the circuit board 3. Among them, the second cavity 1b is used to accommodate the filter assembly 300, and the projections of the second cavity 1b and the heating cavity 2a on a plane perpendicular to the first direction at least partially overlap.

[0050] In the above-mentioned aerosol generating device 100, the heating component 2 is electrically connected to the battery 4 through the circuit board 3. The battery 4 can supply power to the heating component 2. The heating component 2 can heat the aerosol generating matrix 200 in the heating chamber 2a to form an aerosol. The heating component 2 is arranged in the first chamber 1a, and the second chamber 1b is used to accommodate the filter component 300. The heating chamber 2a of the heating component 2 is connected to the second chamber 1b, so that the aerosol formed by the heating component 2 heating the aerosol generating matrix 200 can be transmitted to the filter component 300 in the second chamber 1b, and inhaled by the human body after being filtered by the filter component 300.

[0051] Exemplarily, the aerosol-generating substrate 200 includes, but is not limited to, one or more of cigarettes, tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes.

[0052] By making the projections of the second cavity 1b and the heating cavity 2a on the plane perpendicular to the first direction at least partially overlap, it is convenient for one end of the second cavity 1b to extend toward the heating cavity 2a and communicate with the heating cavity 2a, so that cleaning tools such as brushes or cloth can be extended into the heating cavity 2a along the first direction to clean the heating cavity 2a, and can be extended from the heating cavity 2a or the second cavity 1b to the position where the heating cavity 2a and the second cavity 1b are connected to clean, thereby improving the cleaning convenience of the aerosol generating device 100 and avoiding excessive accumulation of carbonized matter incidental to the aerosol formation process at the position where the heating cavity 2a and the second cavity 1b are connected, thereby affecting the transmission of the aerosol. In addition, the projections of the second cavity 1b and the heating cavity 2a on a plane perpendicular to the first direction at least partially overlap, the third cavity 1c is arranged in parallel with the first cavity 1a in a second direction perpendicular to the first direction, the circuit board 3 is arranged in the third cavity 1c, and the fourth cavity 1d is arranged in parallel with the second cavity 1b in the second direction, and the battery 4 is arranged in the fourth cavity 1d, which is beneficial for making the filter assembly 300, the heating assembly 2, the circuit board 3 and the battery 4 more evenly distributed on the mounting base 1 to avoid accumulation in the same direction, thereby helping to make the structure of the aerosol generating device 100 more compact, reduce the volume of the aerosol generating device 100, and make it more convenient to carry.

[0053] For example, the first direction may be Figure 4 As shown in the Z0-Z1 direction in FIG. , the second direction can be as follows Figure 4 The first direction may be the length direction of the aerosol generating device 100 , and the second direction may be the width direction of the aerosol generating device 100 .

[0054] Specifically, the projections of the second cavity 1b and the heating cavity 2a on a plane perpendicular to the first direction at least partially overlap, and the portion of the second cavity 1b that overlaps with the projection of the heating cavity 2a extends toward the heating cavity 2a, so that the second cavity 1b is connected to the heating cavity 2a. For example, Figure 4As shown, the projection of the portion of the second cavity 1b close to the X0 side on the plane perpendicular to the Z0-Z1 direction overlaps with the projection of the heating cavity 2a on the plane, so that the portion of the second cavity 1b close to the X0 side extends toward the heating cavity 2a along the Z0-Z1 direction to form a conducting channel 1e, so that the second cavity 1b is connected to the heating cavity 2a through the conducting channel 1e, which makes it more convenient for the cleaning tool to extend from the heating cavity 2a or the second cavity 1b into the conducting channel 1e and to more thoroughly clean the wall of the conducting channel 1e.

[0055] like Figure 4 As shown, in some embodiments, the heating chamber 2a extends along the first direction, and the side of the second chamber 1b close to the heating chamber 2a extends along the first direction and communicates with the heating chamber 2a. Figure 4 As shown, the heating chamber 2a extends along the Z0-Z1 direction, and the side of the second chamber 1b close to the heating chamber 2a extends toward the heating chamber 2a along the Z0-Z1 direction to form a conducting channel 1e, and the second chamber 1b is connected with the heating chamber 2a through the conducting channel 1e. In this way, the heating chamber 2a and the conducting channel 1e both extend along the Z0-Z1 direction, which makes it more convenient for a cleaning tool to extend into the conducting channel 1e along the heating chamber 2a to clean the wall surface of the conducting channel 1e, or the cleaning tool can extend into the heating chamber 2a along the conducting channel 1e to clean the wall surface of the heating chamber 2a.

[0056] like Figure 4 As shown, in some embodiments, the second cavity 1b extends along the first direction, and a side of the second cavity 1b close to the heating cavity 2a extends along the first direction and communicates with the heating cavity 2a. Figure 4 As shown, the second cavity 1b extends along the Z0-Z1 direction, and one side of the second cavity 1b close to the heating cavity 2a extends toward the heating cavity 2a along the Z0-Z1 direction to form a conducting channel 1e, and the second cavity 1b is connected with the heating cavity 2a through the conducting channel 1e. In this way, the second cavity 1b and the conducting channel 1e both extend along the Z0-Z1 direction, which makes it more convenient for a cleaning tool to extend into the conducting channel 1e along the second cavity 1b to clean the wall of the conducting channel 1e, or the cleaning tool can extend into the second cavity 1b along the conducting channel 1e to clean the wall of the second cavity 1b.

[0057] Of course, in other embodiments, the side of the second cavity 1b close to the heating cavity 2a may also extend in other directions and communicate with the heating cavity 2a, which is not specifically limited here.

[0058] In some embodiments, the filter assembly 300 is detachably disposed in the second cavity 1b. In this way, the filter assembly 300 can be removed from the second cavity 1b, making it easier for a cleaning tool to enter the second cavity 1b and clean the wall of the second cavity 1b, and also easier for a cleaning tool to enter the position where the second cavity 1b is connected to the heating cavity 2a and clean the position, which is beneficial to improving the cleaning efficiency.

[0059] For example, the filter assembly 300 may be snap-fitted to the mounting seat 1, and / or the filter assembly 300 may be magnetically connected to the mounting seat 1. Figure 5 As shown, the outer periphery of the filter assembly 300 is provided with a first slot and one of the first blocks 301, the wall surface of the second cavity 1b is provided with the first slot and the other of the first blocks 301, and the first block 301 is engaged in the first slot to achieve the engagement between the filter assembly 300 and the mounting seat 1, so that the filter assembly 300 can be detachably arranged in the second cavity 1b.

[0060] Furthermore, if Figure 3 As shown, one end of the filter assembly 300 extends into the heating assembly 2. It can be understood that the projections of the second cavity 1b and the heating cavity 2a on the plane perpendicular to the first direction at least partially overlap, which not only facilitates the communication between the second cavity 1b and the heating cavity 2a, but also facilitates the extension of one end of the filter assembly 300 from the second cavity 1b to the heating cavity 2a, so that the filter assembly 300 at least partially extends into the heating assembly 2, and the aerosol formed by the heating assembly 2 heating the aerosol generating substrate 200 is directly transmitted from the heating cavity 2a to the filter assembly 300, reducing the probability of the carbonized material formed during the heating process adhering to the wall surface at the communication position between the second cavity 1b and the heating cavity 2a, making subsequent cleaning more convenient. At the same time, during the process of the heating assembly 2 heating the aerosol generating substrate 200, the carbonized material adheres to the heating assembly 2 and the one end of the filter assembly 300 extending into the heating cavity 2a, and the carbonized material attached to the filter assembly 300 is taken out with the filter assembly 300 when the filter assembly 300 is replaced, reducing the difficulty of cleaning.

[0061] For example, Figure 3 As shown, the side of the second cavity 1b close to the heating cavity 2a is connected with the heating cavity 2a through the conducting channel 1e, and the filter assembly 300 is partially arranged in the second cavity 1b. The side of the filter assembly 300 close to the heating assembly 2 extends into the heating assembly 2 from the second cavity 1b through the conducting channel 1e, and the part of the filter assembly 300 extending into the heating assembly 2 is provided with an opening connected to the interior of the filter assembly 300. The heating assembly 2 heats the aerosol generating matrix 200 in the heating cavity 2a to form an aerosol, and the aerosol can directly enter the interior of the filter assembly 300 from the opening of the filter assembly 300, thereby reducing the probability of carbonized matter adhering to the wall surface at the connection position between the second cavity 1b and the heating cavity 2a.

[0062] Of course, in other embodiments, when the filter assembly 300 is disposed in the second cavity 1b, the filter assembly 300 may also be spaced apart from the heating assembly 2 along the first direction, which may be adjusted according to actual conditions and is not limited here.

[0063] In some embodiments, the third cavity 1 c communicates with the first cavity 1 a and the fourth cavity 1 d , so that the circuit board 3 is electrically connected to the power supply device and the heating assembly 2 .

[0064] Exemplarily, the circuit board 3 can be electrically connected to the battery 4 and the heating assembly 2 through a flexible electrical connector. The flexible electrical connector includes but is not limited to a flexible circuit board 3 or a flexible electrical conductor.

[0065] In some embodiments, such as Figure 4 As shown, the first cavity 1a and the second cavity 1b are arranged in sequence along the Z0-Z1 direction, the third cavity 1c is located on the X0 side of the first cavity 1a, and the fourth cavity is located on the X0 side of the second cavity 1d, so as to achieve partial overlap of the projections of the second cavity 1b and the heating cavity 2a on a plane perpendicular to the first direction.

[0066] like Figure 4 As shown, further, the projections of the third cavity 1c and the fourth cavity 1d on a plane perpendicular to the first direction at least partially overlap, so as to facilitate the communication between the fourth cavity 1d and the third cavity 1c, and facilitate the electrical connection between the circuit board 3 and the battery 4.

[0067] In some embodiments, the mounting base 1 includes a housing 11 and a bracket 12. The bracket 12 is provided with a second cavity 1b, and the bracket 12 is disposed in the housing 11, and a first cavity 1a, a third cavity 1c, and a fourth cavity 1d are formed between the bracket 12 and the housing 11. The mounting base 1 is formed by assembling the bracket 12 and the housing 11, and after the circuit board 3, the battery 4, and the heating component 2 are mounted on the bracket 12, the circuit board 3, the battery 4, and the heating component 2 are mounted in the housing 11 together with the bracket 12, thereby improving the convenience of assembly. At the same time, the housing 11 and the bracket 12 jointly constitute the first cavity 1a, the third cavity 1c, and the fourth cavity 1d, so that the housing 11 and the bracket 12 play a role in protecting the heating component 2, the circuit board 3, and the battery 4.

[0068] Furthermore, the bracket 12 includes a main body 121 and a mounting portion 122. The main body 121 is provided with a first support 123 and a second support 124 on opposite sides along the first direction. The main body 121, the first support 123, the second support 124 and the shell 11 are enclosed to form a first cavity 1a. The main body 121 and the shell 11 are enclosed to form a third cavity 1c. The mounting portion 122 is provided on a side of the first support 123 away from the second support 124. The mounting portion 122 is provided with a second cavity 1b. The mounting portion 122 and the shell 11 are enclosed to form a fourth cavity 1d. In this way, it is convenient to install the heating component 2, the circuit board 3 and the battery 4 on the bracket 12.

[0069] Specifically, the first cavity 1a and the third cavity 1c are formed on opposite sides of the main body 121 along the second direction, the heating component 2 is located in the first cavity 1a and can be connected to the first support 123 and the second support 124 to achieve fixed installation of the heating component 2, the circuit board 3 is located in the third cavity 1c and can be connected to the main body 121 to achieve fixed installation of the circuit board 3, and the battery 4 can be connected to the mounting portion 122 to achieve fixed installation of the battery 4. The heating component 2, the circuit board 3 and the battery 4 are respectively connected to different parts of the bracket 12 to disperse the load on the bracket 12, avoid stress concentration, and improve the stability of the overall structure.

[0070] For example, the bracket 12 can be connected to the housing 11 by one or more of the following methods: snap connection, adhesive connection, thread connection, etc. Figure 4 As shown, a second card slot and one of the second card blocks 1221 are provided on the outer periphery of the mounting portion 122, and the other of the second card slot and the second card block 1221 is provided on the inner wall surface of the shell 11. When the bracket 12 is installed in the shell 11, the second card block 1221 is engaged with the second card slot to achieve the engagement between the bracket 12 and the shell 11.

[0071] For example, Figure 5 As shown, the first support 123 and the second support 124 have a hollow portion connected to the heating chamber 2a, and the outer shell 11 has a first through hole 11b corresponding to the hollow portion of the second support 124. The aerosol generating substrate 200 at least partially passes through the first through hole 11b of the outer shell 11 and the hollow portion of the second support 124 and is located in the heating chamber 2a of the heating component 2. The heating component 2 can heat the aerosol generating substrate 200 in the heating chamber 2a to form an aerosol, and the aerosol can be transmitted to the filter component 300 through the hollow portion of the first support 123.

[0072] Exemplarily, the outer periphery of the mounting portion 122 forms a receiving groove 122a, and the battery 4 can be disposed in the receiving groove 122a to achieve positioning and installation of the battery 4. Specifically, the battery 4 can be fixed to the wall of the receiving groove 122a by gluing, and / or the battery 4 can be fixed in the receiving groove 122a by snapping.

[0073] For example, the circuit board 3 may be fixed to the main body 121 by gluing, and / or the battery 4 may be fastened to the main body 121 by fasteners, and / or the circuit board 3 may be fixed to the main body 121 by snapping. Figure 3 As shown, a third slot 121 a is formed on the main body 121 , and the circuit board 3 can be snapped into the third slot 121 a to achieve positioning of the circuit board 3 on the main body 121 .

[0074] In some embodiments, the main body 121 is provided with an avoidance hole 121 b, which is used to accommodate predetermined components on the circuit board 3, thereby improving space utilization, further realizing a compact structure of the aerosol generating device 100, and reducing the volume of the aerosol generating device 100.

[0075] Exemplarily, the predetermined element includes but is not limited to a sensor, a capacitor, and the like.

[0076] Exemplarily, the avoidance hole 121b can connect the third cavity 1c and the first cavity 1a. For example, a temperature sensor is provided on the circuit board 3, and the temperature sensor is located in the avoidance hole 121b. The avoidance hole 121b is connected with the first cavity 1a, so that the temperature sensor can detect the temperature in the first cavity 1a and transmit the detection result to the circuit board 3. The control chip on the circuit board 3 can perform corresponding operations according to the detection result.

[0077] In some embodiments, such as Figure 5 As shown, a switch 31 is provided on the side of the circuit board 3 facing away from the main body 121, and the shell 11 is provided with a second through hole 11c connected to the third cavity 1c. The switch 31 can pass through the second through hole 11c and be at least partially located outside the shell 11, so that the user can trigger the switch 31 to control the aerosol generating device 100 to perform corresponding operations.

[0078] Exemplarily, the switch 31 includes but is not limited to a knob switch 31 , a button switch 31 , and the like.

[0079] like Figures 3 to 5 As shown, in some embodiments, the mounting base 1 is further provided with a fifth cavity 1f, and the fifth cavity 1f is located on the side of the first cavity 1a away from the second cavity 1b. The aerosol generating device 100 also includes a bottom cover 5, which is disposed in the fifth cavity 1f, and the bottom cover 5 is provided with a mounting hole 5a, and the mounting hole 5a is penetrated with an electrical contact 51 for contacting and conducting with an external charger, and the electrical contact 51 is electrically connected to the circuit board 3, and the bottom cover 5 is provided with an insertion hole 5b, and the insertion hole 5b is connected to the heating cavity 2a. It can be understood that the electrical contact 51 is disposed on the bottom cover 5 of the fifth cavity 1f, which is convenient for the user to hold the housing 11 to prevent accidental touch, and the bottom cover 5 protects the electrical contact 51 and the flexible electrical connector electrically connected to the electrical contact 51, and is also provided with an insertion hole 5b, so that the aerosol generating matrix 200 can extend from the insertion hole 5b into the heating cavity 2a.

[0080] For example, Figure 4 As shown, the second support 124 and the housing 11 enclose a fifth cavity 1f. Alternatively, a side of the second support 124 away from the first support 123 is provided with the fifth cavity 1f.

[0081] For example, the bottom cover 5 can be connected to the housing 11 by one or more of the following methods: snap connection, adhesive connection, thread connection, etc. Figure 5As shown, the outer periphery of the bottom cover 5 is provided with a fourth card slot 11a and one of the fourth card blocks 52, the inner wall surface of the outer shell 11 is provided with the fourth card slot 11a and the other of the fourth card block 52, and the fourth card block 52 is snapped into the fourth card slot 11a to realize the snap connection between the bottom cover 5 and the outer shell 11.

[0082] Specifically, there may be one or more mounting holes 5a, and there may be one or more electrical contacts 51. Exemplarily, when there are multiple mounting holes 5a, the multiple mounting holes 5a may be arranged around the periphery of the insertion hole 5b, so that the electrical contacts 51 and the flexible electrical connector avoid the insertion hole 5b, so that the aerosol generating substrate 200 extends from the insertion hole 5b into the heating chamber 2a.

[0083] Of course, in other embodiments, the electrical contact 51 may also be disposed on the housing 11 , and the specific configuration may be adjusted according to actual conditions, which is not limited here.

[0084] In some embodiments, a magnetic attraction member is further provided on the bottom cover 5, and the magnetic attraction member is used to be magnetically connected to an external charger so that the electrical contacts 51 on the bottom cover 5 are stably in contact and conductive with the charging terminals of the external charger.

[0085] like Figures 3 to 5 As shown, in some embodiments, the heating component 2 includes a heating element 21, a first channel element 22 and a second channel element 23. The heating element 21 is electrically connected to the circuit board 3, and the heating element 21 is provided with a heating chamber 2a. Among them, the first channel element 22 and the second channel element 23 are located on opposite sides of the first chamber 1a along the first direction and are connected to the mounting seat 1, and the heating element 21 is arranged between the first channel element 22 and the second channel element 23. It can be understood that the heating element 21 is connected to the mounting seat 1 through the first channel element 22 and the second channel element 23, which can simplify the structure of the heating element 21 and is conducive to the manufacture and assembly of the heating component 2. In addition, the first channel element 22 and the second channel element 23 can also be used to control the heat transfer of the heating element 21, thereby reducing the probability of damage to the mounting seat 1.

[0086] Specifically, the first channel member 22 has a first channel 221, and the second channel member 23 has a second channel 231. The first channel 221 and the second channel 231 are respectively connected to the heating chamber 2a. The aerosol generating substrate 200 can extend into the heating chamber 2a of the heating element 21 through the second channel 231. The heating element 21 can heat the aerosol generating substrate 200, and the aerosol formed by heating can be transmitted to the filter assembly 300 through the first channel 221.

[0087] In some embodiments, such as Figure 3 , Figure 6 and Figure 7As shown, one end of the heating element 21 can extend into the first channel 221 and be engaged with the first channel element 22, and the other end can extend into the second channel 231 and be engaged with the second channel element 23, so that the heating element 21 is stably arranged between the first channel element 22 and the second channel element 23. Specifically, the first channel 221 of the first channel member 22 includes a first section 2211 and a second section 2212 sequentially arranged along the first direction, a first step surface is formed between the first section 2211 and the second section 2212, a radial dimension of the second section 2212 matches the outer diameter dimension of the heating element 21, and one end of the heating element 21 can be snapped into the second section 2212 and abut against the first step surface. The second channel 231 of the second channel member 23 includes a third section 2311 and a fourth section 2312 sequentially arranged along the first direction, a second step surface is formed between the third section 2311 and the fourth section 2312, the radial dimension of the third section 2311 matches the outer diameter dimension of the heating element 21, and the other end of the heating element 21 can be snapped into the third section 2311 and abut against the second step surface.

[0088] Exemplarily, the heating element 21 includes a hollow heat-conducting pipe body and a heating resistor circuit on the hollow heat-conducting pipe body. The hollow heat-conducting pipe body forms a heating cavity 2a. The heating resistor circuit is formed on the wall of the hollow heat-conducting pipe body through a thick film printing process. When powered on, the heating resistor circuit generates heat and transfers the heat to the hollow heat-conducting pipe body. The hollow heat-conducting pipe body then transfers the heat to the heating cavity 2a to heat the aerosol generating matrix 200 to generate aerosol.

[0089] In some embodiments, the first channel member 22 is connected to the first support 123, and the second channel member 23 is connected to the second support 124. The first channel 221 of the first channel member 22 can be communicated with the hollow part of the first support 123, and the second channel 231 of the second channel member 23 is communicated with the hollow part of the second support 124. The aerosol generating substrate 200 passes through the hollow part of the second support 124 and the second channel 231 of the second channel member 23 and is then disposed in the heating chamber 2a, so that the heating member 21 can heat the aerosol generating substrate 200, and the aerosol formed by heating can be transmitted to the filter assembly 300 through the first channel 221 of the first channel member 22 and the hollow part of the first support 123.

[0090] Exemplarily, the first channel member 22 is detachably connected to the first support 123, and the second channel member 23 is detachably connected to the second support 124. For example, the first channel member 22 is snap-fitted to the first support 123, such as Figure 7 As shown, and / or, the first channel member 22 is fastened to the first support 123 by fasteners such as screws or bolts. The second channel member 23 is clamped with the second support 124, and / or, the second channel member 23 is fastened to the second support 124 by fasteners such as screws or bolts.

[0091] like Figure 7 As shown, in some embodiments, a third sealing member 27 is provided between the first channel member 22 and the first support 123 to prevent aerosol from leaking from between the first channel member 22 and the first support 123 .

[0092] In some embodiments, one end of the filter assembly 300 may extend into the first channel 221 of the first channel member 22. Exemplarily, one end of the filter assembly 300 may extend into the first section 2211 of the first channel member 22, and the aerosol may enter the filter assembly 300 through the first section 2211 of the first channel member 22, thereby reducing the probability of carbonized matter adhering to the wall surface at the position where the second chamber 1b communicates with the heating chamber 2a. Specifically, as Figure 7 As shown, the radial dimension of the first section 2211 on the side close to the second cavity 1 b is greater than the radial dimension of the side close to the heating cavity 2 a , so as to guide the filter assembly 300 to extend into the first section 2211 .

[0093] like Figure 6 As shown, in some embodiments, the radial dimension of the second channel 231 of the second channel member 23 on the side away from the first channel member 22 is greater than the radial dimension of the side close to the first channel member 22, so that the aerosol generating substrate 200 extends from the side of the second channel 231 of the second channel member 23 away from the heating chamber 2a, and extends into the heating chamber 2a under the guidance of the second channel 231 of the second channel member 23.

[0094] like Figure 4 and Figure 5 As shown, in some embodiments, the heating assembly 2 further includes a heat insulating member 24, which is located at the periphery of the heating member 21, and the opposite ends of the heat insulating member 24 are respectively connected to the first channel member 22 and the second channel member 23. It can be understood that the heat insulating member 24 is located at the periphery of the heating member 21, which can effectively prevent the heat of the heating member 21 from dissipating, improve the heating efficiency, and prevent the heat from being transferred to the mounting seat 1, so that the user can hold the mounting seat 1 to prevent scalding.

[0095] Exemplarily, the heat insulating member 24 may be a tubular structure, which is sleeved on the outer periphery of the heating member 21. For example, the heat insulating member 24 includes a vacuum tube, which is sleeved on the outer periphery of the heating member 21 to prevent the heat of the heating member 21 from dissipating.

[0096] like Figure 4 and Figure 5As shown, further, the heat insulating member 24 and the first channel member 22 are sealed and connected by a first sealing member 25, and / or, the heat insulating member 24 and the channel member are sealed and connected by a second sealing member 26. The heat insulating member 24 and the first channel member 22 are sealed and connected by the first sealing member 25, and the heat insulating member 24 and the second channel member 23 are sealed and connected by the second sealing member 26, so that the heat generated by the heating member 21 is blocked in the air gap formed between the heating member 21 and the heat insulating member 24, so as to further prevent the heat from dissipating and improve the heating efficiency.

[0097] Exemplarily, the first sealing member 25 and the second sealing member 26 may be made of materials such as silicone and rubber.

[0098] Exemplarily, both the first sealing member 25 and the second sealing member 26 may include sealing rings.

[0099] like Figure 5 and Figure 8 As shown, in some embodiments, the second channel member 23 is provided with a first threading hole 232, the second sealing member 26 is provided with one or more second threading holes 261, the second threading hole 261 is communicated with the first threading hole 232, one end of the flexible electrical connector can be electrically connected to the heating member 21, and the other end can extend to the third cavity 1c and be connected to the circuit board 3 after passing through the second threading hole 261 and the first threading hole 232, thereby realizing the electrical connection between the heating member 21 and the circuit board 3 while preventing heat dissipation.

[0100] In some embodiments, the heat insulating member 24 is spaced apart from the main body 121 of the bracket 12 to prevent heat from being transferred to the main body 121 and the circuit board 3 on the main body 121 .

[0101] In some embodiments, the heat insulating member 24 is spaced apart from the outer shell 11 to prevent heat from being transferred to the outer shell 11 , thereby further preventing scalding.

[0102] In some embodiments, the aerosol generating device 100 also includes a detection component, which is electrically connected to the circuit board 3. The detection component is used to detect whether the heating chamber 2a is provided with an aerosol generating matrix 200, to prevent the heating component 2 from being heated due to erroneous operation when there is no aerosol generating matrix 200 in the heating chamber 2a, thereby protecting the heating component 2 and reducing the power loss of the battery 4.

[0103] Further, the detection assembly includes a light detector 61 and a light emitter 62. The second channel member 23 is located on a side of the heating member 21 away from the filter assembly 300, and the light detector 61 and the light emitter 62 are respectively located on opposite sides of the second channel member 23 in a direction perpendicular to the first direction. The second channel member 23 is provided with a light-transmitting portion 233 corresponding to the light detector 61 and the light emitter 62. It can be understood that the aerosol generating matrix 200 needs to extend into the heating chamber 2a of the heating element 21 through the second channel member 23, and the aerosol generating matrix 200 is usually partially exposed to the aerosol generating device 100. For example, the filter section of the cigarette will be exposed outside the aerosol generating matrix 200, so that the user can grab the exposed part and replace the aerosol generating matrix 200. At this time, the aerosol generating matrix 200 will be inserted into the second channel 231 of the second channel member 23, and the light detector 61 and the light emitter 62 are arranged on opposite sides of the second channel 231. It can detect whether there is an aerosol generating matrix 200 in the second channel 231 of the second channel member 23 to block the light, thereby judging whether there is an aerosol generating matrix 200 in the heating chamber 2a.

[0104] Exemplarily, the second channel member 23 is provided with a first light-transmitting hole 2331, and the light-transmitting portion 233 includes the first light-transmitting hole 2331. When the aerosol-generating matrix 200 is not inserted into the second channel member 23, the light emitted by the light emitter 62 can pass through the light-transmitting hole to be transmitted to the light detector 61. Alternatively, the second channel member 23 is provided with a first light-transmitting hole 2331, and a light-transmitting lens 2332 is provided in the first light-transmitting hole 2331. The light-transmitting portion 233 includes the light-transmitting hole and the light-transmitting lens 2332. When the aerosol-generating matrix 200 is not inserted into the second channel member 23, the light emitted by the light emitter 62 can pass through the light-transmitting lens 2332 to be transmitted to the light detector 61. The light-transmitting lens 2332 plays a role in protecting the light detector 61 and the light emitter 62. At the same time, the light-transmitting lens 2332 prevents foreign matter from entering the first light-transmitting hole 2331 and affecting the detection result.

[0105] Specifically, the light detector 61 and the light emitter 62 are located on opposite sides of the second channel member 23 in a direction perpendicular to the first direction. When the aerosol generating substrate 200 is not present in the heating chamber 2a and the second channel 231 of the second channel member 23, the light emitted by the light emitter 62 can be transmitted to the light detector 61. Exemplarily, the light detector 61 and the light emitter 62 are respectively arranged on opposite sides of the second channel member 23 along the second direction, one of the light detector 61 and the light emitter 62 is arranged on the circuit board 3, and the other is electrically connected to the circuit board 3 through the flexible circuit board 3, so as to simplify the electrical connection structure between the detection component and the circuit board 3. Figure 6As shown, the circuit board 3 can extend along the Z0-Z1 direction, and a light detector 61 is provided at a position of the circuit board 3 corresponding to the second channel member 23 along the X0-X1 direction. The main body 121 is provided with an avoidance hole 121b, and the light detector 61 can be located in the avoidance hole 121b. The second support 124 is provided with a second light-transmitting hole 1241, and the outer periphery of the second support 124 forms an annular groove connected to the third cavity 1c. One end of the flexible electrical connector can be connected to the circuit board 3, and the other end is passed through the annular groove to the side of the second channel member away from the light detector 61 and is electrically connected to the light emitter 62, so that the light emitter 62 and the light detector 61 are electrically connected to the circuit board 3.

[0106] Of course, in other embodiments, the detection component may also include a pressure detector or a capacitance detector. For example, when the aerosol generating substrate 200 passes through the second channel member 23, it is pressed against the pressure detector to trigger the pressure detector, thereby realizing detection according to the pressure detection result. The detection may be performed according to actual conditions and is not limited here.
