[0029] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.

[0030] like Figures 1 to 4 As shown, an aerosol-generating device according to one embodiment of the present invention includes a housing 50 and, disposed within the housing 50, a battery 51, a housing 1, a reflector 2, and a heating element 3. The housing 50 can be directly held by a user. Specifically, the housing 50 defines a first cavity, within which the battery 51, the housing 1, the reflector 2, and the heating element 3 are disposed.

[0031] The reflector 2 is disposed inside the housing 1 and may or may not be connected to the housing 1. That is, the housing 1 defines a second cavity, and the reflector 2 is disposed within the second cavity. The reflector 2 and the housing 1 may be detachably connected or integrally connected so as not to be detachable. The housing 1 and the reflector 2 may be roughly cylindrical, and the cross-sectional area of ​​the reflector 2 may be smaller than the cross-sectional area of ​​the housing 1, so that the reflector 2 can be accommodated inside the housing 1. The housing 1 and the reflector 2 may be connected together in a direction perpendicular to the cross-section (axial direction). In some other embodiments, the housing 1 may not be provided, and the reflector 2 may be directly disposed inside the outer shell 50.

[0032] The heating element 3 is arranged inside the reflector 2. That is, the reflector 2 defines a heating cavity 40, and the heating element 3 is arranged in the heating cavity 40. Specifically, the heating element 3 includes a heating base 31 and an infrared radiation layer 32 arranged on the heating base 31. The heating base 31 is a tubular structure that is infrared-transparent, and the space enclosed by the heating base 31 forms the heating cavity 40. The heating cavity 40 is used to accommodate and heat the aerosol generating matrix. Specifically, the heating element 3 is roughly in the shape of a cylinder with openings at both ends. The aerosol generating matrix can be inserted into the heating cavity 40, and the heating element 3 is thereby surrounded by the periphery of the aerosol generating matrix to perform circumferential heating on the aerosol generating matrix.

[0033] Specifically, if Figure 3 As shown, in some embodiments, the infrared radiation layer 32 is provided on the outer circumference or inner circumference of the heating substrate 31. The heating substrate 31 can be a ceramic substrate or a quartz substrate. The surface of the heating substrate 31 is provided with an infrared radiation layer 32, and the outside of the infrared radiation layer 32 is provided with a heating film 30. When the heating film 30 is energized, it generates heat and conducts the heat to the infrared radiation layer 32 on the surface. When the infrared radiation layer 32 is heated, it generates infrared rays, thereby heating the aerosol generating matrix inserted into the heating body 3. The heating principle is as follows: when the heating film 30 of the heating substrate 31 is energized, the heating film 30 generates heat under the action of the current, and the heat is conducted to the infrared radiation layer 32. The infrared radiation layer 32 generates infrared radiation. The infrared radiation passes through the heating substrate 31 and is absorbed by the aerosol generating matrix, thereby heating the aerosol generating matrix. In addition, the heating film 30 will also conduct heat to the heating substrate 31, and then transfer the heat to the aerosol generating matrix through the heating substrate 31. Please refer to Figure 1 The battery 51 is located on one side of the housing 1 and is connected to the conductive film of the heating element 3 to supply power to the heating element 3. In some embodiments, the infrared radiation layer 32 can also be directly powered to generate heat and radiate infrared light.

[0034] When the heating element 3 is powered on and generates heat, some of the heat is conducted to the reflective cover 2 surrounding the heating element 3. That is, the reflective cover 2 absorbs some of the heat generated by the heating element 3, causing the temperature of the reflective cover 2 to rise. This heat, on the one hand, wastes energy and reduces energy efficiency; on the other hand, this heat is conducted to the outer shell 50, causing the outer shell 50 to overheat, affecting the user experience.

[0035] The housing 50 has a first air inlet (not shown), and the reflector 2 has an air flow channel 24. The first air inlet is connected to the air inlet end of the air flow channel 24, and the air outlet end of the air flow channel 24 is connected to the heating chamber 40. Thus, the first air inlet, air flow channel 24, and heating chamber 40 are sequentially connected, allowing outside air to enter the air flow channel 24 from the first air inlet and ultimately reach the heating chamber 40.

[0036] Furthermore, if Figures 2 to 4 As shown, in some embodiments, the housing 1 has a fourth air hole 10. The first air inlet and the air inlet end of the air flow channel 24 are connected through the fourth air hole 10. That is, the fourth air hole 10 is connected to the first air inlet and the air inlet end of the air flow channel 24, respectively, so that the first air inlet, the fourth air hole 10, the air flow channel 24, and the heating chamber 40 are connected in sequence. Outside air can enter the fourth air hole 10 from the first air inlet, then enter the air flow channel 24 from the fourth air hole 10, and finally reach the heating chamber 40.

[0037] In the heating chamber 40, the aerosol generated by the heating element 3 heating the aerosol-generating matrix is ​​mixed with the air entering the heating chamber 40 and then flows out through the upper opening of the shell 50. Since the reflector 2 itself absorbs part of the heat generated by the heating element 3, the temperature of the cold air outside increases when passing through the air flow channel 24. That is, the cold air entering the shell 50 from the first air inlet is preheated through the air flow channel 24 before entering the heating chamber 40 and contacting the aerosol-generating matrix, thereby avoiding direct contact between the cold air and the heating element 3, improving the energy utilization rate of the heating element 3, reducing energy consumption, and improving battery life. On the other hand, since the reflector 2 is located between the heating element 3 and the inner wall surface of the shell 1, part of the heat is isolated in the heating chamber 40, which can reduce the heat transferred from the heating element 3 to the shell 1. In addition, the air flow channel 24 can also continuously take away part of the heat, thereby reducing the heat transferred from the heating element 3 to the shell 50, thereby preventing the user from getting burned when holding the aerosol generating device.

[0038] Two adjacent ones of the first air inlet, the fourth air hole 10, the air flow channel 24, and the heating chamber 40 may be directly connected or indirectly connected. Indirect connection means that other channels may be provided between two adjacent ones of the first air inlet, the fourth air hole 10, the air flow channel 24, and the heating chamber 40.

[0039] Please also read Figures 5 to 8 In some embodiments, the reflector 2 includes a first side wall 21 and a second side wall 22. The first side wall 21 and the second side wall 22 are roughly cylindrical structures with open ends. However, in other embodiments, the first side wall 21 and the second side wall 22 may also be square cylindrical or other shapes. That is, the cross-sectional profiles of the first side wall 21 and the second side wall 22 may be circular, square, polygonal, etc. The cross-sectional dimension of the first side wall 21 is smaller than the cross-sectional dimension of the second side wall 22. The first side wall 21 and the second side wall 22 are respectively connected to the shell 1. The first side wall 21 and the second side wall 22 are spaced apart, and the space between the first side wall 21 and the second side wall 22 forms an air flow channel 24. The heating element 3 can be arranged inside the first side wall 21. That is, the cylindrical first side wall 21 encloses a third cavity, and the heating element 3 can be arranged in the third cavity. Therefore, the cross-sectional dimension of the heating element 3 can be smaller than the cross-sectional dimension of the first side wall 21. Figures 5 to 8 The dashed arrows in the figure indicate the airflow direction.

[0040] Furthermore, in some embodiments, the reflective cover 2 is provided with a reflective layer on at least the surface facing the heating chamber 40. Specifically, the reflective layer can be provided on the inner surface of the first side wall 21. This reflective layer can reflect the infrared light radiated by the heating element 3 back into the heating chamber 40. In other embodiments, the reflective layer can be provided on both the outer surface of the first side wall 21 and the inner surface of the second side wall 22.

[0041] Furthermore, in some embodiments, the reflector 2 further includes at least one first end wall 23, each first end wall 23 being connected between the first side wall 21 and the second side wall 22, and having at least one first air hole 20 formed thereon, each first air hole 20 being in communication with an air flow channel 24. For example Figure 5 and Figure 6 In the illustrated embodiment, the reflector 2 includes two first end walls 23, one of which is located at the air inlet end (the upper end in the figure) of the air flow channel 24, and the other first end wall 23 is located at the air outlet end (the upper end in the figure) of the air flow channel 24. Both first end walls 23 are provided with a plurality of first air holes 20 arranged at intervals. Since the first side wall 21 and the second side wall 22 are connected together by the first end wall 23, the reflector 2 is an integrated structure. Figure 7 and Figure 8 As shown, in other embodiments, the first end wall 23 may not be provided between the first side wall 21 and the second side wall 22, so that the reflector 2 is a split structure. Alternatively, in other embodiments, the number of first end wall 23 may be one, that is, a first end wall 23 is provided at the air inlet end or the air outlet end of the air flow channel 24 to connect the first side wall 21 and the second side wall 22.

[0042] The number of the first air hole 20 is at least one, and can also be more than one (multiple). Figure 5 In the illustrated embodiment, a plurality of first air holes 20 are evenly arranged on the first end wall 23 along the circumference of the reflector 2, and each first air hole 20 has an equal area. In other embodiments, the number, size, and arrangement of the first air holes 20 may be adjusted accordingly based on requirements such as the air intake volume and air intake rate, and the present invention does not impose any restrictions thereto.

[0043] Regarding how the air outlet end of the air flow channel 24 is connected to the heating chamber 40, two different embodiments are provided below as examples for explanation. However, in some other embodiments not shown in the figures, the specific communication path between the air outlet end of the air flow channel 24 and the heating chamber 40 may also be in other forms, and the present invention does not impose any restrictions on this.

[0044] Please also read Figure 9 In the first embodiment of the communication method between the air outlet of the air flow channel 24 and the heating chamber 40, the shell 1 further has a second air hole 152 and a third air hole 153. The second air hole 152 can connect the air outlet of the air flow channel 24 with the outside of the shell 1. That is, the air outlet of the air flow channel 24 and the external air of the shell 1 are connected through the second air hole 152. The third air hole 153 is not connected to the air outlet of the air flow channel 24, and the third air hole 153 can connect the outside of the shell 1 with the heating chamber 40. That is, the air outlet of the air flow channel 24 and the third air hole 153 are connected through the second air hole 152, and the second air hole 152 and the heating chamber 40 are connected through the third air hole 153, so that the air outlet of the air flow channel 24, the second air hole 152, the third air hole 153 and the heating chamber 40 are connected in sequence. Figure 9 The dotted arrows in the figure indicate the airflow path. Thus, the air enters the heating chamber 40 through the air outlet end of the airflow channel 24, the second air hole 152 and the third air hole 153 in sequence. Specifically, the airflow path is the first air hole 20, the airflow channel 24, the second air hole 152, the third air hole 153, and the heating chamber 40. Furthermore, in this embodiment, in order to prevent the air preheated through the airflow channel 24 from dissipating heat outside the shell 1 when passing through the outside of the shell 1, a pipe (not shown) can be provided between the second air hole 152 and the third air hole 153 to connect and seal the two, so that a closed heat-insulating channel is established between the second air hole 152 and the third air hole 153. Thus, the air flowing out from the air outlet end of the airflow channel 24 passes through the second air hole 152, the heat-insulating channel and the third air hole 153 in sequence and then enters the heating chamber 40.

[0045] Please also read Figure 3 、 Figure 4 and Figure 9In some embodiments, the housing 1 includes a second end wall 12, a third end wall 13, and a third side wall 11. The third side wall 11 is connected between the second end wall 12 and the third end wall 13. The fourth air hole 10 is provided on the second end wall 12, and the second air hole 152 and the third air hole 153 are provided on the third end wall 13. Thus, air can flow from the fourth air hole 10 to the second air hole 152 from top to bottom, and then from the third air hole 153 to enter the heating chamber 40 from bottom to top. However, in other embodiments, the fourth air hole 10 can also be provided on the third side wall 11, as long as the fourth air hole 10 is directly or indirectly connected to the air inlet end of the air flow channel 24.

[0046] The second end wall 12, the third end wall 13, and the third side wall 11 may be connected in a detachable manner or in a non-detachable manner. When the second end wall 12, the third end wall 13, and the third side wall 11 are connected in a detachable manner, it is convenient to disassemble the reflector 2 and the heating element 3 inside the housing 1.

[0047] See also Figure 9 and Figure 10 In some embodiments, at least two first bosses 161 are provided on the third end wall 13. Each first boss 161 extends in a direction approaching the second end wall 12. The first sidewall 21 of the reflector 2 is sleeved around the outside of each first boss 161. An air intake gap 160 is formed between two adjacent first bosses 161. The air intake gaps 160 connect the third air holes 153 and the heating chamber 40, respectively. In other words, the third air holes 153 and the heating chamber 40 are connected through the air intake gaps 160. Thus, air entering the housing 1 through the third air holes 153 enters the heating chamber 40 via the air intake gaps 160. The first bosses 161 also facilitate the installation and fixation of the reflector 2.

[0048] Please also read Figure 8 and Figure 11 Regarding the second embodiment of the communication between the outlet end of the air flow channel 24 and the heating chamber 40, a fifth air hole 210 is provided on the first side wall 21 of the reflector 2. The fifth air hole 210 is connected to the outlet end of the air flow channel 24 and the heating chamber 40 respectively. Thus, the air in the air flow channel 24 enters the heating chamber 40 through the fifth air hole 210. Specifically, Figure 8 As shown, the fifth air hole 210 can be a notch extending upward from the lower edge of the first side wall 21. Alternatively, the fifth air hole 210 can also be set at other positions on the first side wall 21 or adopt other shapes.

[0049] like Figure 10As shown, in some embodiments, a second boss 162 is convexly provided on the inner side of the second end wall 12. The second boss 162 extends from the inner wall of the second end wall 12 in a direction close to the third end wall 13. The upper end of the reflector 2 is connected to the second boss 162. Specifically, the upper ends of the first side wall 21 and the second side wall 22 are both connected to the second boss 162. An air intake groove 163 is formed on the second boss 162, and the air intake groove 163 is connected to the air intake end of the fourth air hole 10 and the air flow channel 24 respectively. Thus, the fourth air hole 10 is connected to the air intake end of the air flow channel 24 through the air intake groove 163, and the air entering the fourth air hole 10 flows through the air intake groove 163 and the air flow channel 24 in sequence and then enters the heating chamber 40. The heating element 3 is fixed between the first boss 161 and the second boss 162. In some other embodiments, other communication methods can also be used between the air inlet end of the air flow channel 24 and the fourth air hole 10. For example, the reflector 2 can also be directly connected to the second end wall 12, and the air inlet end of its air flow channel 24 is directly connected to the fourth air hole 10.

[0050] like Figure 3 and Figure 10 As shown, in some embodiments, the housing 1 further includes a second air inlet 14, which is disposed on the third end wall 13. The second air inlet 14 communicates with the heating chamber 40. Specifically, a protrusion 130 extends outward from the bottom of the third end wall 13. This protrusion 130 is hollow, with one end communicating with the exterior of the third end wall and the other end communicating with the heating chamber 40. The second air inlet 14 is disposed at the air inlet end of the protrusion 130. External air can enter the heating chamber 40 simultaneously through the fourth air hole 10 and the second air inlet 14. The air passing through the fourth air hole 10 is preheated air, which reduces heat loss from the heating element 3 and reduces energy consumption. However, the airflow path between the fourth air hole 10 and the heating chamber 40 is relatively long. Air passing through the second air inlet 14 can enter the heating chamber 40 directly, resulting in a shorter airflow path. The simultaneous provision of the fourth air hole 10 and the second air inlet 14 can help ensure sufficient air intake while reducing energy consumption.

[0051] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
