[0027] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0028] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning.

[0029] It should be noted that the term "aerosol" as used in this article refers to a dispersion of solid or liquid particles in a gas. The term "aerosol" as used in this article can generally refer to substances that have been vaporized, atomized, sprayed, or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0030] As used herein, the term "aerosol-generating matrix" refers to any suitable compound or mixture of compounds that facilitates the formation of aerosols (e.g., stable aerosols that are substantially resistant to thermal degradation at the system's operating temperature) during use. Suitable aerosol-generating matrices are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono, di, or triacetic acid esters of glycerol; and aliphatic esters of mono, di, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. Aerosol-generating matrices may include nicotine. Aerosol-generating matrices may include water.

These compounds may be released from the aerosol-generating matrix upon heating.

[0031] This application provides an aerosol generating device (hereinafter referred to as "generating device") that can heat the aerosol generating matrix to form aerosols for user use, and also provide lighting function to facilitate emergency lighting for users. Through the integrated design of lighting and aerosol generation, the number of devices that users need to carry when going out can be reduced, and it has the advantages of being simple, convenient and practical.

[0032] Please see Figures 1 to 6 The generating device includes a housing assembly 100, a heating assembly 200, a power supply assembly 300, and an illumination element 400. The housing assembly 100 provides mounting space for other components (such as the heating assembly 200, the power supply assembly 300, and / or the illumination element 400). The heating assembly 200 generates heat to heat the aerosol generating matrix, causing the aerosol generating matrix to form an aerosol. The power supply assembly 300 supplies power to the electronic components within the generating device (such as the heating assembly 200 and the illumination element 400) and controls the operation of the electronic components (such as turning them on or off). The illumination element 400 solves the problem of the generating device having a single function, broadens the application range of the generating device, and is suitable for scenarios such as outdoor exploration, nighttime outings, or daily emergencies.

[0033] Please see Figure 2The housing assembly 100 has a mounting cavity 110, within which the heating assembly 200 and the power supply assembly 300 are both installed. The housing assembly 100 integrates the heating assembly 200 and the power supply assembly 300 into a single structure, facilitating their carrying and transportation. Simultaneously, it provides protection for the heating assembly 200 and the power supply assembly 300, extending their service life. The power supply assembly 300 includes a battery 310 and a control circuit board 320 electrically connected to each other. The control circuit board 320 is electrically connected to both the heating assembly 200 and the lighting element 400, supplying power to both and controlling their on / off states. The lighting element 400 is disposed within the mounting channel 120, capable of emitting light and projecting it outside the housing assembly 100 to illuminate a target location.

[0034] Please see Figure 3 The control circuit board 320 has a first side 321 and a second side 322 arranged opposite to each other along the first direction Y. The control circuit board 320 divides the mounting cavity 110 inside the housing assembly 100 into a first mounting cavity 111 and a second mounting cavity 112 arranged side by side along the first direction Y. The heating component 200 is disposed in the first mounting cavity 111 and on the first side 321 of the control circuit board 320, and the lighting element 400 is disposed in the second mounting cavity 112 and on the second side 322 of the control circuit board 320. This allows for reasonable planning of the space inside the housing assembly 100 and reduces the wiring layout inside the housing assembly 100. The lighting element 400 can be an incandescent lamp, a fluorescent lamp, or an LED light source, etc.

[0035] Since both the heating component 200 and the lighting element 400 are electrically connected to the control circuit board 320, by placing the heating component 200 and the lighting element 400 in the first mounting cavity 111 and the second mounting cavity 112 formed by the first side 321 and the second side 322 of the control circuit board 320 respectively, the space on both sides of the control circuit board 320 can be reasonably utilized, and its size design can be reduced, thereby helping to reduce the size of the generating device.

[0036] Please continue reading. Figure 2 In some embodiments, the battery 310 and the heating component 200 are arranged side by side in the first mounting cavity 111 along the second direction X, and the second direction X and the first direction Y are perpendicular to each other. The control circuit board 320 is a thin plate structure and is arranged along the second direction X, such that its opposite first side 321 and second side 322 are arranged along the first direction Y. The battery 310 and the heating component 200 are both slender structures and can be arranged at different positions along the second direction on the first side 321 of the control circuit board 320, so as to make reasonable use of the space on the control circuit board 320 and the housing assembly 100 and avoid space waste.

[0037] Of course, in other embodiments, the battery 310, heating component 200, and control circuit board 320 may also be arranged generally along the first direction Y. In this embodiment, to avoid interference between the battery 310, heating component 200, and control circuit board 320, the heating component 200 may be disposed between the battery 310 and the control circuit board 320.

[0038] In some embodiments, the first direction Y is the axial direction of the housing assembly 100. The axial direction of the housing assembly 100 is defined as longitudinal, and the direction perpendicular to it is defined as transverse. In use, the generating device is generally arranged longitudinally, with the heating assembly 200, control circuit board 320, and lighting element 400 arranged sequentially along the longitudinal direction, and the battery 310 and heating assembly 200 arranged transversely. This reduces the transverse dimension and facilitates user gripping. Simultaneously, since the heating assembly 200 and control circuit board 320, and the control circuit board 320 and battery 310 are generally electrically connected via power lines, the longitudinal arrangement of the control circuit board 320 and heating assembly 200, and the battery 310 and control circuit board 320, reduces the number of bent power lines, thereby reducing power line losses, lowering the assembly complexity of the generating device, and reducing its production costs.

[0039] In some embodiments, the length of the housing assembly 100 along the first direction Y is greater than its length along the second direction X, and the housing assembly 100 has a flat structure, that is, the entire generating device has a flat structure, which makes it convenient for the user to grip and hold.

[0040] In some embodiments, the second mounting cavity 112 is provided with a mounting channel 120 communicating with it. The mounting channel 120 extends through the housing assembly 100 along the first direction Y. The lighting element 400 extends from one side of the control circuit board 320 into the interior of the mounting channel 120, facilitating the installation of the lighting element 400. During assembly, the control circuit board 320, the heating assembly 200, and the lighting element 400 can be assembled and then installed together in the mounting cavity 110. Of course, in other embodiments, the mounting channel 120 may extend through the housing assembly 100 along the second direction X.

[0041] Please continue reading. Figure 4 In some embodiments, the mounting channel 120 includes a first mounting section 121 and a second mounting section 122, which are arranged sequentially along the direction away from the control circuit board 320. The size of the second mounting section 122 gradually increases along the direction away from the control circuit board 320 to form a conical structure, thereby reflecting and focusing the light emitted by the lighting element 400, making the light distribution more uniform, reducing lighting dead zones, and improving the overall lighting effect. In this embodiment, the inner surface of the second mounting section 122 is a flat, smooth structure, which can better reflect and focus the light.

[0042] Please see Figure 4 In some embodiments, the housing assembly 100 includes a housing body, a first cover 150 and a second cover 160. The first cover 150 and the second cover 160 are sequentially disposed at the same end of the housing body along the first direction Y from the inside to the outside, and together with the housing body to form a mounting cavity 110. The second cover 160 is provided with a through hole 161 along the first direction Y. The first cover 150 is provided with a mounting portion 151. One end of the mounting portion 151 is connected to the second side 322 of the control circuit board 320, and the other end extends into the through hole 161. The mounting channel 120 passes through the mounting portion 151 along the first direction Y. In this embodiment, the housing body is a hollow structure with one open end. The first cover 150 and the second cover 160 are provided to close the opening, forming a relatively sealed mounting cavity 110. The housing body and the first cover 150 and the second cover 160 are set as detachable structures, which facilitates the assembly of the lighting element 400, the power supply component 300 and the heating element. The through hole 161 can not only facilitate the fixing of the mounting part 151, but also realize the connection between the mounting channel 120 and the outside world, so that light can be emitted to the outside of the housing component 100.

[0043] In some embodiments, the housing body may also include a first housing 130 and a second housing 140, which are arranged sequentially from the inside to the outside. At least a portion of the second cover 160 is inserted into the second housing 140, and a mounting gap 170 is formed between the second cover 160 and the side wall of the second housing 140. The first housing 130 is inserted into the mounting gap 170 to achieve a fixed connection between the first housing 130, the second housing 140, the first cover 150, and the second cover 160. Multiple assembly structures are formed within the first housing 130 for fixing the battery 310 and the heating assembly 200, etc.

[0044] In some embodiments, the heating assembly 200 and the control circuit board 320 may be connected by plug-in, snap-fit, threaded connection, adhesive or soldering.

[0045] In a preferred embodiment, the heating assembly 200 and the control circuit board 320 are snap-fitted together. Please continue reading. Figure 3In this embodiment, the heating component 200 is provided with a hook structure 210, and the control circuit board 320 is provided with a hook interface 323. The hook structure 210 passes through the control circuit board 320 along the first direction Y. The hook structure 210 passes through the hook interface 323 from one side (e.g., the first side 321) of the control circuit board 320 and engages with the other side (e.g., the second side 322) of the control circuit board 320. The hook structure 210 has a certain elasticity, so that it deforms and inserts into the hook interface 323 under the action of external force, and restores its deformation and abuts against the second side 322 after the external force is removed, so as to realize the connection between the control circuit board 320 and the heating component 200. The design of this structure also facilitates the disassembly of the two and helps with inspection and maintenance.

[0046] In some embodiments, in order to improve the stability of the connection, at least two hook structures 210 and hook interfaces 323 are provided, and the hook structures 210 and hook interfaces 323 are provided in a one-to-one correspondence.

[0047] Please see Figure 2 , Figure 5 and Figure 6 In some embodiments, the aerosol generating device further includes a suction assembly 500. The housing assembly 100 is provided with a mounting port 180 communicating with the first mounting cavity 111. The suction assembly 500 is disposed in the first mounting cavity 111 through the mounting port 180 and is connected to the heating assembly 200. The suction assembly 500 includes an outlet 510 and a heating cavity 520 communicating with each other. The heating cavity 520 is used to contain the aerosol generating matrix. At least a portion of the heating assembly 200 is inserted into the heating cavity 520. The generated aerosol can be discharged from the outlet 510 to the outside of the generating device.

[0048] Please continue reading. Figure 6 In some embodiments, the suction assembly 500 includes an outer sleeve 530 and an inner sleeve 540 coaxially arranged. The inner sleeve 540 is disposed inside the outer sleeve 530 and defines a heating chamber 520. An air outlet 510 is formed on the outer sleeve 530. The inner sleeve 540 and the outer sleeve 530 are spaced apart to form an airflow channel 550. The airflow channel 550 is connected to both the air outlet 510 and the heating chamber 520, so that outside air can flow along the airflow channel 550 through the heating assembly 200 and be heated into hot airflow. This achieves dual heating of the aerosol generation matrix airflow and contact heating (including peripheral heating and center heating), thereby improving heating efficiency and increasing the aerosol generation speed and uniformity. The airflow is shown by the arrow in the figure.

[0049] Please continue reading. Figure 3In some embodiments, the heating assembly 200 includes a bracket 220 and a heating element 230. The bracket 220 is disposed between the control circuit board 320 and the suction assembly 500 to support the heating element 230. A hook structure 210 is disposed on the bracket 220. At least a portion of the heating element 230 is inserted into the heating chamber 520 and into the aerosol generating matrix contained in the heating chamber 520, for heating under energized conditions or in an electromagnetic field, so as to heat the aerosol generating matrix by means of central heating.

[0050] In some embodiments, the heating element 230 has a needle-like or rod-like structure, which facilitates insertion into the interior of the aerosol generating matrix. It is made of a heating resistor or conductive ceramic and generates heat when energized, thus heating the aerosol generating matrix via central heating. Alternatively, conductive lines or a conductive film can be provided on the outside or inside of the heating element 230 to provide heat using the principle of resistance heating.

[0051] In other embodiments, the inner sleeve 540 may also serve as a result of increased heat generation, thereby heating the aerosol-generating matrix using circumferential heating. For example, the inner sleeve 540 may also be made of a heating resistor or conductive ceramic.

[0052] Please continue reading. Figure 2 and Figure 5 In some embodiments, the housing assembly 100 is further provided with an operation button 600, which is electrically connected to the control circuit board 320. The operation button is used to control the lighting element 400 to turn on or off through a first operation, and / or to control the heating assembly 200 to turn on or off through a second operation.

[0053] In some embodiments, the suction component 500 and the operation button 600 are disposed on the same side of the housing component 100, both extending along the first direction Y, and can be installed along the first direction Y, which facilitates user operation. The operation button 600 passes through the second housing 140 and the first housing 130 in sequence, is engaged on the inner wall of the first housing 130, and is at least partially exposed in the second housing 140.

[0054] In some embodiments, the first operation can be a preset number of times. Initially, the lighting element 400 is in a closed state. After being pressed a preset number of times (e.g., 5 times), the lighting element 400 is turned on to improve the lighting function for the user. The second operation can be a preset time. Initially, the heating component 200 is in a closed state. After being pressed for a preset time (e.g., 2-3 seconds), the heating component 200 is turned on.

[0055] 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.
