Abstract
Description
Technical Field
[0001] This application relates to the field of aerosol products technology, specifically to an aerosol generating rod and atomizing device. Background Technology
[0002] Currently, in common aerosol generators used in HNB (heated non-combustible) atomizing devices, one end is typically used for suction, while the other end is inserted into the heating chamber of the HNB atomizing device. The atomizing matrix is stored near the insertion end so that it can be heated by the heater to generate an aerosol. Due to structural limitations, these aerosol generators have a limited atomizing matrix capacity, making them difficult to reuse multiple times. Afterward, a new aerosol generator needs to be replaced, resulting in some waste and relatively high user costs. Utility Model Content

[0036] An aerosol generating rod is an atomizing matrix carrier that can be used with an atomizing device. It generates aerosol by heating the internal atomizing matrix for inhalation. Typically, to fit the insertion port and heating chamber of the atomizing device, the aerosol generating rod is a cylindrical rod-shaped structure. The aerosol generating rod provided in this application overcomes the shortcomings of existing aerosol products, such as limited atomizing matrix storage space, small capacity, and single-use capability. It features at least two matrix segments spaced apart within the generating rod body, each storing atomizing matrix. When used with a HNB (Heated Tobacco Bulb) atomizing device, either end of the generating rod can be inserted into the atomizing device for heating in a first direction. After the atomizing matrix in one matrix segment is used up, the other end of the generating rod can be inserted into the atomizing matrix, causing the atomizing matrix in the corresponding segment at the other end to generate aerosol, thus enabling multiple uses of a single aerosol generating rod.
[0037] The following describes some embodiments of the aerosol generating rod and atomizing device provided in this application with reference to the accompanying drawings.
[0038] An embodiment of the first aspect of this application provides an aerosol generating rod 100, such as Figure 1 , Figure 2 , Figure 3 As shown, the aerosol generating rod 100 includes a generating rod body 1, which extends along a first direction, i.e., the length direction of the generating rod body 1 is the first direction. Both ends of the generating rod body 1 have a suction nozzle section 12, which the user can place in their mouth for suction. The generating rod body 1 contains at least two matrix sections 11, which are spaced apart and interconnected along the first direction, and each matrix section 11 stores an atomizing matrix. When used with an atomizing device, when either end of the generating rod body 1 is inserted into the atomizing device, a matrix section 11 corresponding to the inserted end can extend into the heating chamber of the atomizing device. The heating component of the atomizing device heats the atomizing matrix within the matrix section 11, causing it to atomize and generate an aerosol. When a user inhales through the nozzle section 12 at the other end, the generated aerosol can pass through the other matrix sections 11 and the nozzle section 12 located outside the atomizing device with the airflow and enter the mouth. During this process, the unheated matrix sections 11 and the external nozzle section 12 can cool the airflow and prevent scalding. When the atomizing matrix in one matrix section 11 is exhausted, the aerosol generating rod 100 can be removed from the atomizing device, and the other end of the aerosol generating rod 100 can be inserted into the atomizing device to heat the corresponding matrix section 11 at the other end.
[0039] As is understandable, common aerosol products are designed with an insertion end on one side and a suction end on the other. The aerosol product has only one area inside for storing the atomizing matrix, usually located near the insertion end, while the other end has a nozzle for the user to inhale. Due to structural limitations, aerosol products with this structure are typically disposable, meaning they can only support a single use. Once the stored atomizing matrix is depleted, a new aerosol product needs to be replaced.
[0040] In this embodiment, the aerosol generating rod 100 has been improved and optimized in structure, so that at least two matrix segments are arranged at intervals in the middle of the aerosol generating rod 100, and each matrix segment stores the atomizing matrix. In the HNB atomization device, the aerosol generating rod 100 only heats the atomizing matrix in one matrix segment each time it is used, so that one aerosol generating rod 100 can be used multiple times, which can effectively reduce waste, improve utilization rate, and improve user experience.
[0041] It should be noted that in practical applications, the aerosol generating rod 100 can be matched with existing atomizing equipment. The heating component of the atomizing equipment can adopt a circumferential heating method or a central heating method, both of which can be effectively adapted to the aerosol generating rod 100 in this embodiment.
[0042] In further embodiments of this application, such as Figure 3 As shown, the generating rod body 1 is also provided with a hollow section 13. A hollow section 13 is provided between any two adjacent matrix sections 11 so that the adjacent matrix sections 11 can be connected through the hollow section 13, so that aerosols and gases can pass through normally and provide space for aerosols to mix with air, making the mixing more uniform. In addition, the hollow section 13 can separate the adjacent matrix sections 11, preventing heat conduction between adjacent matrix sections 11, making the heating object more precise.
[0043] The length of the hollow section 13 in the first direction can be set according to the specific dimensions of the generating rod body 1 and the matrix section 11, as well as the atomized matrix storage capacity of the matrix section 11, so as to simultaneously meet the requirements of separating the matrix section 11 and mixing the aerosol airflow.
[0044] Furthermore, in a specific implementation, such as Figures 1 to 3In the example, the generating rod body 1 is provided with two matrix segments 11, that is, in the first direction, each end of the hollow segment 13 is connected to a matrix segment 11, and each matrix segment 11 corresponds to one of the suction nozzle segments 12; wherein, at least one matrix segment 11 is provided with a vent hole 111, the vent hole 111 penetrates the matrix segment 11 in the first direction, such that one end of the vent hole 111 extends to the corresponding suction nozzle segment 12, and the other end extends to the hollow segment 13, thereby forming an airflow channel for the aerosol mixed gas to pass through.
[0045] Furthermore, in a specific example, such as Figure 3 As shown, both matrix sections 11 are provided with vent holes 111. When one end of the generating rod body 1 is inserted into the heating chamber of the atomizing device, for example... Figure 3 When the bottom end of the aerosol generating rod 1 extends into the heating chamber, a matrix segment 11 near the bottom end is heated. The generated aerosol moves upward under the influence of airflow. The vent 111 of the matrix segment 11 near the top acts as an airflow channel, allowing the aerosol-gas mixture to pass through, thus preventing the aerosol from being absorbed by the unheated atomizing matrix and affecting the inhalation experience. In this embodiment, when either end of the aerosol generating rod 100 is inserted into the atomizing device for heating, the vent 111 of the unheated matrix segment 11 can serve as an airflow channel. Therefore, one end of the generating rod 1 can be randomly inserted into the atomizing device during use.
[0046] Furthermore, in another specific example, such as Figure 4 In the example, of the two substrate segments 11, one has a vent 111, while the other does not. In use, the substrate segment 11 without the vent 111 can be inserted first into the heating chamber of the atomizing device for heating, for example... Figure 4 The bottom end of the generator rod 100 is inserted into the heating chamber first. At this time, the vent 111 in the other matrix segment 11 can serve as an airflow channel for the aerosol mixture to pass through. When the atomizing matrix in the matrix segment 11 without vent 111 is exhausted, an airflow channel is formed in the matrix segment 11. Then, the other end of the generator rod body 1 is inserted into the heating chamber. The atomizing matrix in the matrix segment 11 with vent 111 is heated to generate aerosol. At this time, the matrix segment 11 without vent 111 has formed an airflow channel, which can allow the aerosol mixture to pass through, and will not cause the aerosol to be absorbed by the atomizing matrix. In practical applications, corresponding markings can be made on the outer surface of the generator rod body 1 to distinguish between the matrix segment 11 with vent 111 and the matrix segment 11 without vent 111, so that users can accurately know the insertion order of the aerosol generator rod 100 before use.
[0047] Furthermore, in a specific example, such as Figure 3 , Figure 4As shown, inside the generating rod body 1, the diameter of the vent 111 is smaller than the inner diameter of the hollow section 13, and the inner diameter of the hollow section 13 is smaller than the inner diameter of any matrix section 11. When the atomized matrix of the matrix section 11 is heated to generate aerosol, the inner diameter of the aerosol narrows as it enters the hollow section 13, causing the aerosol to move laterally. This promotes the mixing of the aerosol with air, resulting in a more uniform aerosol mixture and a better taste. As the aerosol mixture flows through the vent 111 of another matrix section 11 to the corresponding nozzle section 12, the diameter of the vent 111 is further reduced, which can increase the flow rate of the aerosol mixture to meet the air output requirements of the nozzle section 12. This allows the aerosol mixture to be discharged from the nozzle section 12 in sufficient quantity with the suction action. In addition, the temperature of the aerosol mixture can be reduced accordingly as it passes through the vent 111 and the nozzle section 12, thereby achieving the effect of cooling and preventing scalding.
[0048] Furthermore, in a specific example, such as Figure 3 As shown, in the matrix section 11 with vent 111, there is one vent 111, and the vent 111 is coaxially arranged with the matrix section 11, that is, the vent 111 is located at the central axis of the corresponding matrix section 11. This ensures that during the process of the aerosol mixture in the hollow section 13 entering the vent 111, the distances of the aerosol mixture in different directions on the inner circumference of the hollow section 13 to the inlet of the vent 111 are basically equal, which can keep the flow of aerosol mixture in different directions unobstructed and prevent blockage in local areas due to excessive flow distance.
[0049] In another specific example, such as Figure 5 As shown, in the matrix section 11 with ventilation holes 111, the number of ventilation holes 111 is at least two. In this case, at least two ventilation holes 111 can be arranged at intervals along the circumference of the matrix section 11 so that the arrangement of the ventilation holes 111 is relatively dispersed, so that the aerosol mixed gas of the hollow section 13 can flow into the ventilation holes 111. Preferably, at least two ventilation holes 111 can be arranged evenly along the circumference of the matrix section 11. In addition, the number of ventilation holes 111 can also be set according to the usage requirements. The specific number is not limited to the two shown in the figure. Three, four or other numbers can also be set.
[0050] In further embodiments of this application, such as Figure 3As shown, the aerosol generating rod 100 adopts a symmetrical design. Within the rod body 1, two nozzle segments 12 and two matrix segments 11 are symmetrically arranged relative to the center of the rod body 1 in the first direction. That is, the distances from the center to the two matrix segments 11 are equal, ensuring that when either end is inserted into the atomizing device, the corresponding matrix segment 11 can align with the heating chamber, allowing the heating component to completely cover the atomized matrix within the matrix segment 11, thus improving heating efficiency. The two matrix segments 11 have identical structures, and each matrix segment 11 is provided with a vent hole 111. During manufacturing, the atomized matrix storage capacity and processing procedures for both matrix segments 11 are identical, eliminating the need for sequential differentiation and simplifying the processing operation, thereby improving production efficiency. Furthermore, during use, the inhalation experience is essentially the same when either end of the aerosol generating rod 100 is inserted into the atomizing device for heating.
[0051] In further embodiments of this application, such as Figure 4 As shown, the aerosol generating rod 100 adopts a symmetrical design. Specifically, within the generating rod body 1, two nozzle segments 12 and two matrix segments 11 are symmetrically arranged relative to the center position of the generating rod body 1 in the first direction. That is, the distances from the center position to the two matrix segments 11 are equal, ensuring that when either end is inserted into the atomizing device, the corresponding matrix segment 11 can align and engage with the heating chamber, allowing the heating component to completely cover the atomizing matrix within the matrix segment 11, thereby improving heating efficiency. Of the two matrix segments 11, one has a vent hole 111, while the other does not. In use, the substrate segment 11 without vents 111 can be inserted into the heating chamber of the atomizing device first for heating. At this time, the vents 111 in the other substrate segment 11 can serve as an airflow channel for the aerosol mixture to pass through. When the atomizing substrate in the substrate segment 11 without vents 111 is exhausted, an airflow channel is formed in the substrate segment 11. When the other end of the generating rod body 1 is inserted into the heating chamber, the atomizing substrate in the substrate segment 11 with vents 111 is heated to generate aerosol. At this time, the airflow channel formed by the substrate segment 11 without vents 111 can be used for the aerosol mixture to pass through. During the manufacturing process, the corresponding amount of atomizing substrate can be filled according to the different structural forms of the two substrate segments 11. Corresponding markings can be made on the outer surface of the generating rod body 1 to distinguish between the substrate segment 11 with vents 111 and the substrate segment 11 without vents 111, so that users can accurately know the insertion order of the aerosol generating rod 100 before use.
[0052] In further embodiments of this application, such as Figure 6In the example shown, both matrix segments 11 of the generating rod body 1 are provided with vents 111. Specifically, in the radial direction of the generating rod body 1, the atomizing matrix in one matrix segment 11 is distributed near the central axis, while the atomizing matrix in the other matrix segment 11 is distributed away from the central axis. The two matrix segments 11 correspond to atomization devices with different heating methods. For example... Figure 6 In the example, the substrate segment 11 near the bottom is the first substrate segment 113, which has a first vent 1131 coaxially arranged within it. The first substrate segment 113 has a thicker wall, and correspondingly, the vent 1131 has a relatively smaller diameter, causing the atomized substrate stored in the first substrate segment 113 to be radially closer to the central axis. The substrate segment 11 near the top is the second substrate segment 114, which has a second vent 1141 coaxially arranged within it. The second substrate segment 114 has a thinner wall, and correspondingly, the vent 1141 has a relatively larger diameter, causing the atomized substrate stored in the second substrate segment 114 to be radially farther away from the central axis and closer to the radially outer edge of the second substrate segment 114.
[0053] In use, the first matrix section 113 is compatible with an atomizing device employing a central heating method, for example... Figure 7 In the example, the heating component in the atomizing device has a central heating column 222. When the first matrix section 113 of the aerosol generating rod 100 extends into the heating chamber, the central heating column 222 penetrates into the first vent 1131 and contacts the atomizing matrix in the circumferential direction. The atomizing matrix is heated by the heat generated by the central heating column 222. Since the atomizing matrix in the first matrix section 113 is concentrated near the central axis, it is closer to the central heating column 222 in the radial direction, which allows the atomizing matrix to be fully heated and the atomization effect to be better. The second matrix section 114 is adapted to atomizing devices that use a circumferential heating method, such as... Figure 8 In the example, the heating component of the atomizing device has a heating tube 221. When the second matrix section 114 of the aerosol generating rod 100 extends into the heating chamber, the second matrix section 114 is located inside the heating tube 221. The heating tube 221 heats the atomizing matrix inside the second matrix section 114 in the circumferential direction. Since the atomizing matrix inside the second matrix section 114 is distributed near the radial outer side, it is closer to the heating tube 221, which can make the atomizing matrix fully heated and effectively enhance the atomization effect.
[0054] It is understandable that, due to the different settings and positions of the heating elements in circumferential heating and central heating, the coverage of the high-temperature zone is different. In existing aerosol generating rods, when the matrix segment is used in a central heating column, the atomized matrix near the outer edge is far from the central heating column, resulting in insufficient heating and low atomization efficiency. Correspondingly, when the same matrix segment is used in a circumferentially heated heating tube, the atomized matrix near the central axis is far from the heating tube, making it easy for some atomized matrix to be insufficiently heated and resulting in poor atomization effect.
[0055] In this embodiment, the aerosol generating rod 100 employs two matrix segments 11 with different structures to correspond to atomizing devices with different heating methods. Of course, it is also applicable to atomizing devices with two heating functions at the same time (i.e., atomizing devices with both heating tubes and central heating columns). Depending on the different atomizing matrix distributions of the matrix segments 11, a suitable heating method can be activated to ensure that the atomizing matrix is fully heated and atomized, thereby improving the utilization rate of the atomizing matrix.
[0056] In further embodiments of this application, such as Figure 9 As shown, in the generator body 1, the nozzle section 12 is filled with a flexible breathable structure 121. The flexible breathable structure 121 allows the aerosol mixture to pass through and can cool the aerosol mixture to a certain extent without affecting the taste. The flexible breathable structure 121 can deform. When used in an atomizing device that uses a central heating method, the central heating column of the atomizing device can pass through the flexible breathable structure 121 and extend into the corresponding matrix section 11 to heat the atomizing matrix. The flexible breathable structure 121 can still only wrap around the circumferential outer side of the central heating column, without affecting the normal passage of the aerosol mixture through the flexible breathable structure 121.
[0057] In further embodiments of this application, such as Figures 1 to 3 As shown, in the generating rod body 1, a plurality of microporous structures 122 are provided within the nozzle section 12. These microporous structures 122 extend along a first direction to allow the aerosol mixture to pass through. The pore size of the microporous structures 122 can be adjusted according to the particle size of the aerosol. The plurality of microporous structures 122 can be constructed using methods such as... Figure 2 The arrangement of the multiple ring arrays shown can, of course, be used in other ways, such as a matrix arrangement. Furthermore, the nozzle structure can be made of a pierceable flexible structure, so that when applied to an atomizing device using a central heating method, the central heating column of the atomizing device can pierce the nozzle structure and extend into the corresponding matrix segment 11 to centrally heat the atomizing matrix.
[0058] In further embodiments of this application, such as Figure 9In the example, within the generating rod body 1, a corresponding breathable baffle structure 112 can be provided within the matrix section 11. This breathable baffle structure 112, together with the sidewall of the matrix section 11, forms a cavity for storing the atomized matrix, thus confining the atomized matrix within it and preventing leakage. When the atomized matrix is heated and atomized, the generated aerosol can flow normally through the breathable baffle structure 112. In one specific example, the breathable baffle structure 112 can form a vent hole 111, preventing the atomized matrix from passing through the breathable baffle structure 112 and entering the vent hole 111, thereby avoiding blockage. Alternatively, other structures can be used to form the vent hole 111, creating a circumferentially impermeable structure; the specific configuration can be determined according to actual usage requirements.
[0059] An embodiment of the second aspect of this application provides an atomizing device 200 for heating and atomizing the aerosol generating rod 100 in any of the embodiments of the first aspect described above. For example... Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown, the atomizing device 200 includes a main housing 210, a heating component 220, and a power supply component 230. The main housing 210 serves as a mounting carrier, with an insertion port 211 at one end in a first direction. The main housing 210 also contains a heating chamber 212, which communicates with the insertion port 211. The heating component 220 is located within the heating chamber 212. The power supply component 230 is located inside the main housing 210 and electrically connected to the heating component 220 to supply power, causing the heating component 220 to heat up when energized. Either end of the aerosol generating rod 100 can pass through the insertion port 211 and be inserted into the heating chamber 212, allowing a corresponding matrix segment 11 to be contained within the heating chamber 212. The heating component 220 heats the atomizing matrix in the matrix segment 11, causing it to atomize and generate an aerosol. With the user's inhalation action, the aerosol mixes with air to form an aerosol mixture, which flows through the other matrix segments 11 towards the suction end. When the atomizing matrix of the matrix segment 11 at one end of the aerosol generating rod 100 is exhausted, the aerosol generating rod 100 can be taken out and rotated 180° so that the other end of the aerosol generating rod 100 can be inserted into the heating chamber 212 of the atomizing device 200 to heat the atomizing matrix in another matrix segment 11, thereby extending the service life of a single aerosol generating rod 100.
[0060] It should be noted that in the atomizing device 200 of this application, the heating component 220 can adopt a circumferential heating method (e.g., Figure 12 (as in the example), a central heating method can also be used (such as...) Figure 13The examples in the text can all be adapted to the aerosol generating rod 100 in any of the embodiments of the first aspect described above.
[0061] The following describes a specific example of the aerosol generating rod 100 and atomizing device 200 of this application with reference to the accompanying drawings.
[0062] like Figures 1 to 3 as well as Figures 9 to 13 As shown, the atomizing device 200 is specifically a heat-not-burning device; the size of the aerosol generating rod 100 is adapted to the atomizing device 200, and the two can be used together. The aerosol generating rod 100 includes a cylindrical generating rod body 1, which extends along a first direction. The generating rod body 1 is internally provided with two nozzle sections 12, two matrix sections 11, and a hollow section 13, and the generating rod body 1 is symmetrically arranged in the first direction. The two nozzle sections 12 are located at both ends of the generating rod body 1; the hollow section 13 is located in the middle of the generating rod body 1 and is divided into two symmetrical parts by the axis of symmetry of the generating rod body 1. The two ends of the hollow section 13 are connected to the two matrix sections 11, and the end of each matrix section 11 away from the hollow section 13 is connected to a corresponding nozzle section 12. The two nozzle sections 12 and the two matrix sections 11 are all symmetrically arranged with respect to the axis of symmetry of the generating rod body 1.
[0063] like Figure 9 In the example, the nozzle section 12 has a flexible, breathable structure 121; the generating rod body 1 has at least two matrix sections 11 inside, which are spaced apart and interconnected along a first direction, and each matrix section 11 stores atomized matrix. Each of the two matrix sections 11 has a vent 111, which penetrates the corresponding matrix section 11 along the first direction and is coaxial with the matrix section 11. Inside the generating rod body 1, the diameter of the vent 111 is smaller than the inner diameter of the hollow section 13, and the inner diameter of the hollow section 13 is smaller than the inner diameter of any matrix section 11. The distances from the two matrix sections 11 to the axis of symmetry of the generating rod body 1 are equal, and each matrix section 11 stores atomized matrix.
[0064] Correspondingly, such as Figures 10 to 13As shown, the atomizing device 200 includes a main housing 210, a heating assembly 220, and a power supply assembly 230. The main housing 210 has an insertion port 211 at its top in a first direction, the size and shape of which are adapted to the aerosol generating rod 100. The main housing 210 has an internal support structure 213 that divides the internal space into different chambers. A heating chamber 212 is formed in the chamber above the support structure 213 by a supporting structure. The heating chamber 212 communicates with the insertion port 211, and a corresponding air passage structure is formed within the heating chamber 212. The heating assembly 220 is disposed in the heating chamber 212 to heat the matrix segment 11 of the aerosol generating rod 100 inserted into the heating chamber 212. The power supply component 230 is located inside the main housing 210. The power supply component 230 includes a battery 231 and an electronic control board 232. The battery 231 is located in the cavity below the support structure 213. The electronic control board 232 is located on the side of the battery 231 and extends along the first direction to one side of the heating cavity 212. The electronic control board 232 has a control circuit and is electrically connected to the battery 231 and the heating component 220 to control the battery 231 to supply power to the heating component 220, so that the heating component 220 heats up when powered on.
[0065] Specifically, the heating element 220 can employ either circumferential heating or central heating. For example... Figure 12 In the example, the heating assembly 220 includes a heating tube 221, which is arranged along a first direction and corresponds to the insertion port 211. The outer wall of the heating tube 221 has a heating resistor, which is connected to the electrode of the battery 231 through a lead. When any end of the aerosol generating rod 100 passes through the insertion port 211 and extends into the heating chamber 212, a corresponding matrix segment 11 also extends into the inner side of the heating tube 221. When the user performs a suction action through the suction nozzle segment 12 at the other end of the aerosol generating rod 100, the electronic control board 232 controls the battery 231 to supply power to the heating resistor of the heating tube 221 to heat the matrix segment 11 extending into the heating tube 221, causing the atomizing matrix inside to be heated and atomized to generate aerosol. At the same time, external air enters the interior of the aerosol generating rod 100 through the air passage structure. The generated aerosol mixes with the air to form an aerosol mixed gas, which flows to the suction nozzle segment 12 at the other end of the aerosol generating rod 100 under negative pressure and then flows into the user's mouth. The aerosol mixed gas can produce a cooling effect when passing through the other matrix segment 11 and the other suction nozzle segment 12 to prevent scalding. When the atomizing matrix of one matrix segment 11 is exhausted, the aerosol generating rod 100 can be taken out and rotated 180° to insert the other end into the heating chamber 212 to heat another matrix segment 11, thus achieving secondary use.
[0066] like Figure 13In the example, the heating assembly 220 includes a central heating column 222, which is disposed at the center of the heating cavity 212 along a first direction, and the top of the central heating column 222 has a spike structure. When any end of the aerosol generating rod 100 passes through the insertion port 211 and extends into the heating chamber 212, the central heating column 222 can penetrate into the interior of the aerosol generating rod 100 and extend into the corresponding matrix section 11. When the user performs a suction action through the suction nozzle section 12 at the other end of the aerosol generating rod 100, the electronic control board 232 controls the battery 231 to supply power to the heating resistor of the heating tube 221 to heat the matrix section 11 extending into the heating chamber 212, so that the atomizing matrix inside is heated and atomized to generate aerosol. At the same time, external air enters the interior of the aerosol generating rod 100 through the air passage structure. The generated aerosol mixes with the air to form an aerosol mixed gas, which flows to the suction nozzle section 12 at the other end of the aerosol generating rod 100 under negative pressure and then flows into the user's mouth. The aerosol mixed gas can produce a cooling effect when passing through the other matrix section 11 and the other suction nozzle section 12 to prevent scalding. When the atomizing matrix of one matrix segment 11 is exhausted, the aerosol generating rod 100 can be taken out and rotated 180° to insert the other end into the heating chamber 212 to heat another matrix segment 11, thus achieving secondary use and effectively reducing waste.
[0067] When the heating component 220 of the atomizing device 200 is equipped with both a heating element 221 and a central heating column 222, after each end of the aerosol generating rod 100 extends into the heating chamber 212, different areas of the matrix segment 11 extending into the heating chamber 212 can be heated respectively through the heating element 221 and the central heating column 222. For example, the heating element 221 can be activated first to heat the atomized matrix near the radial outer part of the matrix segment 11. When the atomized matrix in this area is exhausted, the heating element can be switched to the central heating column 222 to heat the atomized matrix in the area near the radial center of the matrix segment 11, thus enabling each end of the aerosol generating rod 100 to be used twice. When the atomized matrix of a matrix segment 11 is completely exhausted, the other end of the aerosol generating rod 100 is inserted into the heating chamber 212, and the above heating operation is repeated, so that each aerosol generating rod 100 can be used four times, thereby further improving the utilization rate and reducing waste.
[0068] One option is to install an airflow sensor inside the main housing 210 corresponding to the heating chamber 212. The airflow sensor is electrically connected to the electronic control board 232 so that when the user performs a suction action, the airflow sensor generates a sensing signal, and the electronic control board 232 controls the battery 231 to supply power to the heating component 220 according to the sensing signal. Alternatively, a corresponding button can be installed on the main housing 210, and the button is electrically connected to the electronic control board 232. The battery 231 supplies power to the heating component 220 by manually operating the button.
[0069] Furthermore, when the atomizing device 200 in this embodiment is used in conjunction with the aerosol generating rod 100 in any of the above embodiments, it can achieve all the beneficial effects of the aerosol generating rod 100, which will not be elaborated here.
[0070] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
