Description

Technical Field

[0001] The present application relates to the field of aerosol technology, and in particular to an atomization device and an aerosol generating equipment. Background Art

[0002] An atomizer is a device that generates an aerosol by heating an aerosol matrix without burning it. In existing liquid storage atomizers, the liquid storage chamber mostly adopts a fixed sealing structure, which can easily cause leakage and poor liquid supply due to the imbalance of internal and external pressures in the liquid storage chamber. For example, when the external air pressure or temperature changes, the internal pressure of the liquid storage chamber may be higher than the external air pressure, causing the aerosol matrix in the liquid storage chamber to leak to the outside of the atomizer under the action of the air pressure difference. For another example, during the use of the atomizer, as the aerosol matrix is ​​continuously consumed, a large negative pressure will be generated in the liquid storage chamber, causing problems such as poor liquid supply. Obviously, the occurrence of problems such as leakage and poor liquid supply will have a serious impact on the performance and user experience of the atomizer. Utility Model Content

[0031] See also Figures 1 to 6 An embodiment of the present application provides an atomization device that can provide a usable aerosol by heating an aerosol matrix stored inside the device; the atomization device includes a shell assembly 100, a pressure regulating assembly 200, a heating assembly 300, and other functional components that exist as needed, which are described in detail below.

[0032] See also Figures 1 to 3The shell assembly 100 can be understood as a collection of related components that constitute the overall outer contour structure of the atomizer. The user can hold, move, store, operate and use the atomizer with the help of the shell assembly 100; the shell assembly 100 is formed with a relatively independent liquid storage space and an air flow channel 100b; wherein the liquid storage space is mainly used to provide a corresponding structural space for the pressure regulating assembly 200 and the aerosol matrix, and a pressure relief hole 100a is provided through the shell wall of the shell assembly 100, and the liquid storage space can be connected with the outside world (i.e., the outside of the shell assembly 100 or the atomizer) through the pressure relief hole 100a; the air flow channel 100b is formed inside the shell assembly 100 and is arranged through the shell assembly 100, and is mainly used to provide a path for guiding the air flow to and from the shell assembly 100 or the atomizer, for example, the air flow outside the atomizer can enter through the air inlet of the air flow channel 100b, and the aerosol generated inside the atomizer can be discharged from the air outlet of the air flow channel 100b following the air flow.

[0033] It should be noted that, for the convenience of description, in some of the following embodiments, the liquid storage space is defined as the internal space of the shell assembly 100 .

[0034] In one embodiment, see Figures 1 to 3 The shell assembly 100 includes a shell member 110 and an end seat member 120; wherein the shell member 110 has a first end and a second end opposite to each other, the second end of the shell member 110 is an open structure, and the end seat member 120 is inserted or sealed and fixed to the second end of the shell member 110, so that the shell member 110, the end seat member 120 and the side wall of the air flow channel 100b are used to enclose the internal space of the shell assembly 100, and the pressure relief hole 100a is set through the shell wall of the shell member 110; at the same time, an air guide pipe 111 extending from the first end of the shell member 110 to the second end is provided inside the shell member 110, and the air guide pipe 111 is connected with the end seat member 120 to enclose the air flow channel 100b.

[0035] In some embodiments, the air guide tube 111 may be protruded from the first end of the outer shell 100 and may be used as a nozzle of the atomizing device. For example, a user may inhale the generated aerosol through the air guide tube 111 .

[0036] See also Figures 1 to 3The pressure regulating assembly 200 is fixedly arranged inside the shell assembly 100, and the pressure regulating assembly 200 divides the internal space of the shell assembly 100 into a pressure relief chamber 100c and a liquid storage chamber 100d that are not connected to each other, that is, the pressure relief chamber 100c and the liquid storage chamber 100d are located on opposite sides of the pressure regulating assembly 200, and the gas in the pressure relief chamber 100c cannot directly enter the liquid storage chamber 100d through the pressure regulating assembly 200; wherein, the pressure relief hole 100a is located at a position of the shell assembly 100 corresponding to the pressure relief chamber 100c, so that the pressure relief chamber 100c can maintain communication with the outside through the pressure relief hole 100a; the liquid storage chamber 100d is mainly used to store aerosol matrix, and the liquid storage chamber 100d is connected to the air flow channel 100b to provide structural support for the aerosol matrix in the liquid storage chamber 100d to enter the heating assembly 300 in the form of penetration or the like.

[0037] The pressure regulating component 200 is configured so that at least a part of the structure or part can be elastically deformed due to the change of the air pressure inside and outside the liquid storage chamber 100d, so as to adaptively balance the air pressure inside and outside the liquid storage chamber 100d; specifically, when the air pressure in the liquid storage chamber 100d is greater than the external air pressure, the pressure regulating component 200 can be bulged and deformed toward the side of the pressure relief chamber 100c (for example, a local part of the pressure regulating component 200) to prevent the aerosol matrix from flowing out too much from the liquid storage chamber 100d to the heating component 300 and causing liquid leakage; when the air pressure in the liquid storage chamber 100d is less than the external air pressure, the pressure regulating component 200 can be bulged and deformed toward the side of the liquid storage chamber 100d to prevent the aerosol matrix from flowing out of the liquid storage chamber 100d to the heating component 300 from being unsmooth; when the air pressure in the liquid storage chamber 100d is equal to the external air pressure, the pressure regulating component 200 can undergo a restoring elastic deformation.

[0038] In some embodiments, the pressure regulating assembly 200 may be arranged transversely inside the housing assembly 100 to separate the internal space of the housing assembly 100 into a pressure relief chamber 100c and a liquid storage chamber 100d that are longitudinally arranged side by side.

[0039] In some embodiments, the pressure regulating assembly 200 may also be longitudinally arranged inside the housing assembly 100 to separate the internal space of the housing assembly 100 into a pressure relief chamber 100c and a liquid storage chamber 100d that are laterally arranged side by side.

[0040] In some embodiments, the pressure regulating assembly 200 can also be arranged inside the shell assembly 100 around the axis of the air flow channel 100b to divide the internal space of the shell assembly 100 into a liquid storage chamber 100d and a pressure relief chamber 100c that are concentrically arranged inside and outside.

[0041] In one embodiment, see Figure 1 and Figure 2 The pressure regulating assembly 200 includes a sealing diaphragm 210, which is transversely fixed to the inside of the outer shell 110 and arranged opposite to the end seat 120, so that the side of the sealing diaphragm 210 facing the end seat 120 and the outer shell 110 and the end seat 120 encloses a liquid storage chamber 100d, and the side of the sealing diaphragm 210 away from the end seat 120 and the outer shell 110 encloses a pressure relief chamber 110c; correspondingly, the air guide 111 is set through the sealing diaphragm 210, and the pressure relief hole 110a can be set through the shell wall of the outer shell 110 near its first end (for example, the top side wall of the outer shell 110 in the longitudinal direction). When the internal and external air pressures of the liquid storage chamber 100d change, relying on the structural characteristics of the sealing diaphragm 210 that can undergo elastic deformation, the internal and external air pressures of the liquid storage chamber 100d can be adaptively balanced by adjusting the volume of the liquid storage chamber 100d.

[0042] In some embodiments, the sealing membrane 210 can also be longitudinally fixed inside the outer shell 110 and arranged opposite to the air duct 111 at intervals; for example, the sealing membrane 210 can be fixed between the inner wall of the first end of the outer shell 110 and the inner wall of the end seat 120, and arranged side by side with the air duct 111 at intervals; thereby, a pressure relief chamber 100c and a liquid storage chamber 100d that are arranged side by side in a transverse manner can be formed inside the shell assembly 100. For another example, the sealing membrane 210 can be fixed around the air duct 110 between the inner wall of the first end of the outer shell 110 and the inner wall of the end seat 120, thereby forming a liquid storage chamber 100d and a pressure relief chamber 100c that are concentrically distributed inside and outside the shell assembly 100; relying on the structural characteristics of the sealing membrane 210 that can undergo elastic deformation, the internal and external air pressures of the liquid storage chamber 100d can also be automatically balanced in real time.

[0043] See also Figures 1 to 3 The heating component 300 is disposed inside the shell component 100 and is located at a position corresponding to the air flow channel 100b; the heating component 300 is mainly used to heat the aerosol matrix entering the heating component 300 from the liquid storage chamber 100d to generate a usable aerosol in the air flow channel 100b.

[0044] In some embodiments, see Figure 1 and Figure 3The heating assembly 300 can be constructed by combining the atomizing tube 310, the heating element 320, etc.; wherein the atomizing tube 310 is connected and arranged between the air guide tube 111 and the end seat 120 to form the air flow channel 100b; the heating element 320 is arranged inside the atomizing tube 310. The heating element 320 can be a combination structure of a nautilus heating wire and a porous material body such as a liquid guide cotton, porous ceramics, or a combination structure of a mesh heating element and a porous material body such as a liquid guide cotton, porous ceramics, etc.; the porous material body can be used to attract the aerosol matrix in the liquid storage chamber 100d, so that the heating element 320 can heat the atomized aerosol matrix and generate aerosol in the air flow channel 100b.

[0045] In some embodiments, the heating assembly 300 and its combined structure with the housing assembly 100 may also refer to the prior art and will not be described in detail herein.

[0046] Thus, on the one hand, the pressure regulating assembly 200 (specifically, the sealing diaphragm 210) is used to divide the internal space of the housing assembly 100 into a liquid storage chamber 100d and a pressure relief chamber 100c located on opposite sides of the pressure regulating assembly 200, and the pressure relief chamber 100c is connected to the outside world by means of the pressure relief hole 100a. When the air pressure on the opposite sides of the pressure regulating assembly 200 changes or an air pressure difference occurs, the elastic deformation of the pressure regulating assembly 200 can be relied on to automatically adjust the volume of the liquid storage chamber 100d in real time, thereby adaptively balancing the storage pressure. The internal and external air pressure of the liquid chamber 100d can not only avoid the leakage of aerosol matrix and poor liquid supply caused by the imbalance of the internal and external pressure of the liquid storage chamber 100d (for example, the change of the external environment temperature), for example, it can avoid the problem that the aerosol matrix excessively flows into the air flow channel 100b due to the excessive air pressure in the liquid storage chamber 100d, and then leaks to the outside of the atomization device; for example, it can avoid the problem that the aerosol matrix cannot smoothly penetrate into the heating component 300 due to the excessively low air pressure in the liquid storage chamber 100d, thereby causing the problem of burnt smell.

[0047] On the other hand, by disposing the pressure regulating assembly 200 (specifically the sealing diaphragm 210 ) inside the housing assembly 100 , the pressure regulating assembly 200 can be hidden, thereby forming effective protection for the pressure regulating assembly 200 .

[0048] It should be noted that Figure 2 The bold dashed line with an arrow in the middle represents the approximate flow direction of the aerosol matrix in the liquid storage chamber 100d. Figure 2 The solid line with an arrow in the middle represents the general direction or path of the airflow flowing into and out of the atomizing device through the airflow channel 100b.

[0049] In one embodiment, see Figures 1 to 6The pressure regulating assembly 200 further includes a sealing bracket 220, which is mainly used to stably fix the sealing diaphragm 210 inside the housing assembly 100 to ensure that the sealing diaphragm 210 can play a stable sealing and isolating role between the liquid storage chamber 100d and the pressure relief chamber 100c. Figure 1 , Figure 2 and Figure 6 The sealing bracket 220 has a through-hole structure 220a, that is, the through-hole structure 220a penetrates from the side of the sealing bracket 220 facing the pressure relief chamber 100c to the side of the sealing bracket 220 facing the liquid storage chamber 100d;

[0050] Accordingly, see Figure 1 , Figure 2 and Figure 5 The sealing diaphragm 210 includes a sealing cover portion 211 and a surrounding wall portion 212; wherein the sealing cover portion 211 is stacked on one side of the sealing bracket 220 and covers the through-hole structure 220a, for example, the sealing cover portion 211 is stacked on the side of the sealing bracket 220 facing the pressure relief chamber 100c or the side facing the liquid storage chamber 100d; the surrounding wall portion 212 is connected to the contour edge of the sealing cover portion 211 and is enclosed around the geometric center line of the sealing cover portion 211, so that the surrounding wall portion 212 can cover the side of the sealing bracket 220.

[0051] Therefore, when the pressure regulating assembly 200 is fixed inside the shell assembly 100, the sealing bracket 220 can be used to squeeze or press the surrounding wall portion 212 between the side of the sealing bracket 220 and the inner wall of the shell assembly 100, so that with the help of the sealing bracket 220, not only can the sealing diaphragm 210 be stably fixed inside the shell assembly 100 to form a liquid storage chamber 100d and a pressure relief chamber 100c that are sealed and isolated from each other, but the sealing bracket 220 can also form a structural support for the sealing diaphragm 210 to ensure that the sealing diaphragm 210 can adapt to the changes in the air pressure inside and outside the liquid storage chamber 100d and undergo stable elastic deformation.

[0052] In some embodiments, the sealing bracket 220 can be omitted, and the sealing diaphragm 210 can be firmly assembled and fixed inside the housing assembly 100 by directly designing the material thickness of different parts of the sealing diaphragm 210; for example, the material thickness and hardness of the surrounding wall portion 212 are set to be greater than the material thickness and hardness of the sealing cover portion 211, so as to ensure that the surrounding wall portion 212 has a strong mechanical structural strength and is not prone to structural deformation as a whole; and the sealing cover portion 211 is equivalent to the part of the sealing diaphragm 210 that can undergo elastic deformation. Therefore, the surrounding wall portion 212 is connected to the housing assembly 100 in a sealed contact, and the internal space of the housing assembly 100 is divided into a liquid storage chamber 100d and a pressure relief chamber 100c by means of the sealing cover portion 211, so as to achieve the effect of automatically balancing the air pressure inside and outside the liquid storage chamber 100d.

[0053] In some embodiments, the sealing membrane 210 may also omit the surrounding wall portion 212, and the cover portion 211 may be fixed to the sealing bracket 220 by means of gluing, welding, etc., and the cover portion 211 may seal the cover through-hole structure 220a; in this way, the sealing membrane 210 and the sealing bracket 220 may be constructed into an integrated structure, and the internal and external air pressures of the liquid storage chamber 100d may be adaptively balanced by taking advantage of the elastic deformation of the cover portion 211. Of course, in order to ensure the sealing isolation effect between the liquid storage chamber 100d and the pressure relief chamber 100c, a sealing structural member such as a sealing ring may be provided at the contact portion between the sealing bracket 220 and the housing assembly 100.

[0054] In one embodiment, see Figure 4 The sealing membrane 210 and the sealing bracket 220 are each an integrally formed ring structure, and the two cooperate with each other to form a pressure regulating assembly 200 that is laterally fixed inside the housing assembly 100. For details, please refer to Figure 6 The sealing bracket 220 includes an inner sleeve 221, an outer sleeve 222 and an annular plate 223; wherein the inner sleeve 221 and the outer sleeve 222 are arranged concentrically and spaced apart from each other, and the annular plate 223 is located between the same ends of the inner sleeve 221 and the outer sleeve 222 in the axial direction, thereby forming an annular air groove structure in the sealing bracket 220, and the through hole structure 220a is arranged through the annular plate 223 and communicates with the annular air groove. In some embodiments, the through hole structure 220a may include a plurality of through holes, and the plurality of through holes are spaced apart around the geometric center line of the sealing bracket 220.

[0055] For sealing diaphragm 210, see Figure 5 The covering portion 211 is an annular structure, and the surrounding wall portion 212 includes an inner surrounding wall portion 212a connected to the inner ring edge of the covering portion 211 and an outer surrounding wall portion 212b connected to the outer ring edge of the covering portion 211. It can also be understood that the inner surrounding wall portion 212a and the outer surrounding wall portion 212b are arranged concentrically and spaced apart relative to the covering portion 211.

[0056] See also Figure 1 and Figure 2 When the pressure regulating assembly 200 is fixed inside the shell assembly 100, the cover portion 211 and the ring plate portion 223 are arranged opposite to each other with a spacing, that is, the cover portion 211 is arranged facing the notch of the ring plate portion 223 to cover the annular air groove structure; the inner surrounding wall portion 212a is clamped and fixed between the inner sleeve portion 221 and the air guide pipe 111, and the outer wall portion 212b is clamped and fixed between the inner sleeve portion 222 and the inner wall of the outer shell 110.

[0057] In some embodiments, the sealing portion 211 can be located on the side of the pressure regulating assembly 200 facing the pressure relief chamber 100c, while the annular plate portion 223 is located on the side of the pressure regulating assembly 200 facing the liquid storage chamber 100d; in this way, not only can the erosion of the aerosol matrix on the sealing diaphragm 210 be minimized, but also conditions can be created for the sealing portion 211 to stably undergo elastic deformation.

[0058] Firstly, by designing the structural form of the sealing diaphragm 210 and the sealing bracket 220, the sealing diaphragm 210 (specifically the inner wall portion 212a and the outer wall portion 212b) can be squeezed and fixed to the outer wall of the air duct 111 and the inner wall of the outer shell 110 with the help of the sealing bracket 220 (specifically the inner sleeve portion 221 and the outer sleeve portion 222), thereby achieving a firm fixation of the sealing diaphragm 210 and ensuring the sealing performance of the sealing diaphragm 210 between the liquid storage chamber 100d and the pressure relief chamber 100c.

[0059] Secondly, by arranging the cover part 211 and the ring plate part 223 at intervals, sufficient structural space can be provided for the cover part 211 to undergo elastic deformation, so that the cover part 211 cannot adapt to the change in air pressure due to structural interference of the ring plate part 223 or the sealing bracket 220 and undergo elastic deformation of an adaptive range.

[0060] Thirdly, by setting the through hole structure 220a at the ring plate portion 223 and arranging them at intervals around the geometric center line of the sealing bracket 220, it is beneficial to enhance the balance of the air pressure acting on the cover portion 211 or the sealing diaphragm 210, creating favorable conditions for improving the stable elastic deformation of the sealing diaphragm 210.

[0061] In some embodiments, according to the difference in the installation position of the pressure regulating assembly 200 inside the shell assembly 100 (or the difference in the spatial arrangement of the pressure relief chamber 100c and the liquid storage chamber 100d), the sealing bracket 220 and the sealing diaphragm 210 can adopt a corresponding structural form; for example, the sealing bracket 220 and the sealing diaphragm 210 both adopt an annular sleeve structure, the sealing diaphragm 210 is sleeved on the periphery of the sealing bracket 220, and a folded edge structure can be provided at both axial ends of the sealing diaphragm 210, and the folded edge structure of the sealing diaphragm 210 is squeezed and fixed to the inner wall of the outer shell member 110 and the inner wall of the end seat member 120 by means of the axial end face of the sealing bracket 220, and the air guide tube 111 is coaxially arranged to penetrate the sealing bracket 220, thereby configuring the liquid storage chamber 100d and the pressure relief chamber 100c that are concentrically isolated and distributed inside and outside.

[0062] In one embodiment, see Figure 2 , Figure 4 and Figure 6 The sealing bracket 220 also includes a limiting flange 224, which is arranged to protrude from the outer circumferential surface of the outer sleeve portion 222 along the radial direction of the ring plate portion 223; correspondingly, the inner wall of the outer shell 100 is provided with a limiting step 112 with the step surface facing the end seat 120; when the pressure regulating component 200 is assembled in the outer shell 110, the limiting step 112 can be used to abut the limiting flange 224, thereby limiting the pressure regulating component 200 to a preset position in the outer shell 110.

[0063] In this way, through the structural relationship between the limiting step 112 and the limiting flange 224 abutting against each other, the stability of the structural assembly of the pressure regulating assembly 200 inside the shell assembly 100 can be further improved, thereby preventing the pressure regulating assembly 200 from affecting the sealing between the liquid storage chamber 100d and the pressure relief chamber 100c due to position displacement as a whole.

[0064] In one embodiment, see Figure 4 and Figure 5 Combined with Figure 1 and Figure 2 The sealing diaphragm 210 also includes a rib structure 213, which is enclosed around the geometric center line of the cover portion 211 and is arranged on a side of the surrounding wall portion 212 facing the shell assembly 100; for example, the rib structure 213 is arranged on the inner circumferential surface of the inner surrounding wall portion 212a and the outer circumferential surface of the outer wall portion 212b.

[0065] When the pressure regulating assembly 200 is fixed inside the shell assembly 100, the inner sleeve 221 can be used to squeeze the rib structure 213 onto the outer peripheral surface of the air duct 111 to eliminate the structural gap between the air duct 111 and the sealing diaphragm 210; the outer sleeve 222 can be used to squeeze the rib structure 213 onto the inner wall of the outer shell 111 to eliminate the structural gap between the sealing diaphragm 210 and the inner wall of the outer shell 111, thereby achieving a stable fixation of the sealing diaphragm 210 and improving the sealing between the liquid storage chamber 100d and the pressure relief chamber 100c.

[0066] Of course, the rib structure 213 can be disposed alone or simultaneously on the side of the surrounding wall portion 212 facing the sealing bracket 220 (eg, the outer sleeve portion 222 and the inner sleeve portion 221 ), which can also ensure that the sealing membrane 210 is firmly fixed and achieves stable sealing of the sealing membrane 210 .

[0067] See also Figure 7 Combined with Figures 1 to 6 The embodiment of the present application further provides an atomizing device, which is mainly different from the atomizing device of the aforementioned embodiment in that the pressure relief chamber 100c is omitted, that is, the pressure regulating assembly 200 is arranged at the pressure relief hole 100a.

[0068] Specifically, the pressure regulating assembly 200 is fixed to the housing assembly 100 in the form of a sealed cover or a sealed pressure relief hole 100a, thereby separating the liquid storage chamber 100d from the outside of the housing assembly 100. When the internal and external air pressures of the liquid storage chamber 100 (or the air pressures on opposite sides of the pressure regulating assembly 200) change, the internal and external air pressures of the liquid storage chamber 100 can be adaptively balanced by relying on the structural characteristics of the pressure regulating assembly 200 that can undergo elastic deformation, thereby avoiding problems such as liquid leakage and poor liquid supply.

[0069] In one embodiment, see Figure 7 The pressure regulating assembly 200 may include a sealing diaphragm 210, which may adopt a plug-type structure having a sealing portion 211 and a surrounding wall portion 212; wherein the surrounding wall portion 212 surrounds the geometric center line of the sealing portion 211 and is connected to the contour edge of the sealing portion 211, and at the same time, the material thickness and structural strength of the surrounding wall portion 212 may be set to be greater than or much greater than the material thickness and structural strength of the sealing portion 211; the surrounding wall portion 212 is inserted into the pressure relief hole 100a in the form of an interference fit, so that the sealing portion 211 can cover the pressure relief hole 100a; in this way, when the air pressure inside and outside the liquid storage chamber 100d or the air pressure on opposite sides of the sealing portion 211 changes, the sealing portion 211 can be caused to undergo elastic deformation, thereby achieving the effect of balancing the air pressure inside and outside the liquid storage chamber 100d.

[0070] In one embodiment, please combine Figures 1 to 7The pressure regulating assembly 200 can also refer to the pressure regulating assembly 200 in the atomizing device of the aforementioned embodiment, and is constructed by combining a sealing bracket 220 and a sealing diaphragm 210; wherein the sealing bracket 220 is inserted into the pressure relief hole 100a to seal and fix the sealing diaphragm 210 at the pressure relief hole 100a, thereby realizing the sealing and covering of the pressure relief hole 100a. Specifically, the sealing bracket 220 has a through-hole structure 220a arranged through, and the covering portion 211 is superimposed on the sealing bracket 220 and the covering through-hole structure 220a is arranged; the surrounding wall portion 212 is clamped or squeezed and fixed between the side of the sealing bracket 220 and the hole wall of the pressure relief hole 100a.

[0071] Please combine Figures 1 to 7 The embodiment of the present application also provides an aerosol generating device, including a host device and the atomizing device of the aforementioned embodiment; wherein the host device can be understood as a collection of functional devices such as a controller and a battery cell, and the host device is electrically connected to the heating component 300 to control the heating component 300; for example, with the help of the host device, the heating component 300 can be controlled to start or stop heating the aerosol matrix, and for another example, with the help of the host device, the heating mode, heating power, etc. of the heating component 300 can be adjusted.

[0072] The host device and the atomization device can be relatively independent functional structures, and the two can be combined in a detachable manner such as snap-on, adsorption connection, plug-in connection, etc. to form a complete aerosol generating device; the host device can also be fixedly arranged inside the atomization device to be combined with the atomization device to form a non-detachable aerosol generating device.

[0073] Based on the pressure regulating component 200 provided in the atomizing device, the internal and external air pressures of the liquid storage chamber 100d can be adaptively adjusted to avoid leakage, poor liquid supply and other problems in the aerosol generating device during transportation and application, thereby effectively improving the user experience of the aerosol generating device.

[0074] It should be noted that the aerosol matrix described in this application can be a liquid medium such as physiological saline, liquid medicine, liquid extract, and tobacco oil; for example, the components of a typical aerosol matrix are propylene glycol, glycerol, nicotine, and flavor substances. It is understandable that the aerosol matrix does not constitute a limitation on the atomization device or aerosol generating device of this embodiment. The aerosol matrix can be determined according to the application scenario of the atomization device or aerosol generating device. For example, an electronic cigarette can be a specific application embodiment of the aerosol generating device.

[0075] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
