Description

Technical Field

[0001] This application relates to the field of heating atomization and aerosol generation technology for heating without combustion, specifically to an aerosol generation device, and also to a heating without combustion atomization appliance including the above-mentioned aerosol generation device. Background Technology

[0002] Heated tobacco products (HNB) are a new type of tobacco product that simulates the smoking experience of traditional cigarettes by heating rather than burning them.

[0003] In the field of heated tobacco products, infrared radiation heating, compared to contact heat conduction heating, eliminates the need for a heat transfer medium during the heating process, resulting in a healthier, less polluting smoking experience and more uniform heating. However, the heating structure of the heating atomization (i.e., aerosol generation) device in most infrared radiation HNB (Heated Tobacco Unit) devices on the market is generally in direct contact with the cigarette, resulting in contact heat conduction heating. This does not achieve complete heat radiation heating, affecting heating uniformity and consequently impacting the smoking experience. Utility Model Content

[0004] In view of this, the purpose of this application is to provide an aerosol generating device to improve heating uniformity.

[0005] The purpose of this application is also to provide a heated non-combustible atomizing device including the above-mentioned aerosol generating device, so as to improve heating uniformity.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An aerosol generating apparatus, comprising:

[0008] The support member is provided with a placement cavity for placing the aerosol generation substrate. The support member includes a supporting bottom surface and a supporting side surface that is connected to the supporting bottom surface. The supporting side surface is light-transmitting, and the outer bottom surface of the support member opposite to the supporting bottom surface is a first light-reflecting surface.

[0009] An infrared heating element is used to provide infrared radiation energy to heat and atomize the aerosol-generating substrate;

[0010] A radiation flux control hood is provided to cover the infrared heating element.

[0012] The support member has a second gap with the side of the radiation flux control hood, and the inner wall of the radiation flux control hood is a second light reflecting surface;

[0013] The first light-reflecting surface and the second light-reflecting surface work together to ensure that the infrared radiation energy of the infrared heating element is evenly applied to the side of the support member.

[0014] Preferably, in the above-mentioned aerosol generating device, the infrared heating element and the support are arranged coaxially, and the infrared radiation energy of the infrared heating element is uniformly distributed along its circumference.

[0015] Preferably, in the above-mentioned aerosol generating device, the radiation flux control hood includes:

[0017] The second radiation flux control body includes a second radiation flux control ring disposed around the outer periphery of the infrared heating element, and the second radiation flux control ring is sealed and connected to the first radiation flux control ring.

[0018] The second light-reflecting surface includes the inner wall of the first radiation flux control ring and the inner wall of the second radiation flux control ring.

[0019] Preferably, in the above-described aerosol generating apparatus, the portion of the second radiation flux control ring closest to the first radiation flux control ring gradually narrows from one end close to the first radiation flux control ring to the other end.

[0020] Preferably, in the above-mentioned aerosol generating device, the side of the second radiation flux control ring is arranged in an inwardly convex target curve.

[0021] Preferably, in the above-mentioned aerosol generating device, the target curve is a target function curve, and the target function curve and the power function curve are symmetrical with respect to the target straight line L;

[0022] Wherein, the origin of the coordinate system is a point where the axis of the infrared heating element is aligned with the end of the second radiant flux control ring furthest from the first radiant flux control ring; the radial direction of the infrared heating element is the x-axis; and the axial direction of the infrared heating element is the y-axis. The power function curve satisfies the following conditions:

[0023] y = ax b +c, the first point (r1, 0) and the second point (r2, h) are located at the two ends of the power function curve, and b is the target power;

[0024] The target straight line L satisfies the following condition:

[0025]

[0026] Where r1 is the inner diameter of the end of the second radiation flux control ring furthest from the first radiation flux control ring, r2 is the inner diameter of the end of the second radiation flux control ring closest to the first radiation flux control ring, and h is the axial dimension of the second radiation flux control ring.

[0027] Preferably, in the above-described aerosol generating apparatus, the first radiation flux control body further includes a radiation flux control plate, the radiation flux control plate being connected between the end of the first radiation flux control ring away from the second radiation flux control ring and the support member and parallel to the support bottom surface of the support member; the second light reflecting surface further includes the inner wall of the radiation flux control plate; and / or

[0028] The end of the second radiation flux control ring closest to the first radiation flux control ring is flush with or substantially flush with the supporting bottom surface of the placement cavity; and / or

[0029] At least the outer side of the second radiation flux control ring is wrapped with a heat insulation layer.

[0030] Preferably, in the above-mentioned aerosol generating device, the infrared heating element includes:

[0031] A heating assembly includes a spiral heating wire extending along its axial direction and electrode pins electrically connected to the heating wire, and a radiation flux control shroud covers the heating assembly;

[0032] The lamp holder is sealed to the radiation flux control cover to form an infrared radiation cavity. The heating component is disposed in the lamp slot of the lamp holder and the electrode pins extend out of the lamp holder.

[0033] Preferably, in the above-mentioned aerosol generating device, the support member is cylindrical, and a light-reflecting film is provided on the outer bottom surface of the support member to form the first light-reflecting surface.

[0034] Preferably, in the above-mentioned aerosol generating device, the outer side of the radiation flux control cover is covered with an elastic sleeve that can fix the support member, the elastic sleeve has a fixing hole for the support member to pass through, and the end of the support member away from the support bottom surface is provided with an outer edge that overlaps the outer side of the elastic sleeve.

[0035] As can be seen from the above technical solution, the aerosol generating device provided in this application includes a support member with a placement cavity for placing the aerosol generating substrate. The support member includes a supporting bottom surface and a supporting side surface that is connected to the supporting bottom surface. The supporting side surface is light-transmitting, and the outer bottom surface of the support member opposite to the supporting bottom surface is a first light-reflecting surface. An infrared heating element is used to provide infrared radiation energy to heat and atomize the aerosol generating substrate. A radiation flux control cover is used to cover the infrared heating element. The support member is placed inside the radiation flux control cover, and the first light-reflecting surface is opposite to the infrared heating element and has a first gap. The support member and the side surface of the radiation flux control cover have a second gap, and the inner wall of the radiation flux control cover is a second light-reflecting surface. The first light-reflecting surface and the second light-reflecting surface cooperate to make the infrared radiation energy of the infrared heating element act uniformly on the side surface of the support member.

[0036] When the aerosol generating apparatus provided in this application is used, the aerosol generating substrate is placed in the placement cavity of the support member; and infrared light waves are generated by the infrared heating element. Combined with the second light reflecting surface of the radiation flux control cover and the first light reflecting surface of the support member, the infrared radiation energy of the infrared heating element is uniformly applied to the side of the support member through the second gap between the side of the support member and the side of the radiation flux control cover, so that the aerosol generating substrate is heated and atomized.

[0037] Because the infrared heating element and the first light reflecting surface of the support have a first gap, the infrared heating element and the support do not contact each other. Therefore, during the process of heating and atomizing the aerosol generating substrate, there is no contact heat conduction between the infrared heating element and the aerosol generating substrate in the support, which can achieve complete thermal radiation heating, thereby improving the heating uniformity and thus enhancing the suction experience.

[0038] This application also provides a heat-not-burning atomizing device, including an aerosol generating device for heating and atomizing and an electronic component for supplying power to the aerosol generating device. The electronic component is electrically connected to the aerosol generating device. The aerosol generating device can be any of the aforementioned aerosol generating devices. Since the aforementioned aerosol generating devices have the above-mentioned effects, the heat-not-burning atomizing device with the aforementioned aerosol generating device has the same effects, so it will not be described in detail here.

[0039] Preferably, the above-mentioned heated non-combustible atomizing appliance further includes:

[0040] The first conductive element is disposed at the position corresponding to the insertion port of the support element;

[0041] A second conductive element is movably disposed radially between the inlet and the first conductive element along the support member, and the second conductive element is capable of making electrical contact with the first conductive element;

[0042] An elastic element is provided that can cause the second conductive element to separate from the first conductive element, and the elastic element is connected to the second conductive element.

[0044] One of the first conductive element and the second conductive element is electrically connected to the positive electrode of the electronic component, and the other is electrically connected to the negative electrode of the electronic component. Attached Figure Description

Detailed Implementation

[0055] This application provides an aerosol generating device and a heated non-combustible atomizing appliance, which improves heating uniformity.

[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] like Figure 1-4 As shown, the aerosol generating device provided in this embodiment includes a support member 3 with a placement cavity for placing the aerosol generating substrate 1. The support member 3 includes a supporting bottom surface and a supporting side surface that is connected around the supporting bottom surface. The supporting side surface is light-transmitting, and the outer bottom surface of the support member 3 opposite to the supporting bottom surface is a first light-reflecting surface 31. An infrared heating element is used to provide infrared radiation energy to heat and atomize the aerosol generating substrate 1. A radiation flux control cover is used to cover the infrared heating element. The support member 3 is placed inside the radiation flux control cover, and the first light-reflecting surface 31 is opposite to the infrared heating element and has a first gap. The support member 3 and the side surface of the radiation flux control cover have a second gap, and the inner wall of the radiation flux control cover is a second light-reflecting surface. The first light-reflecting surface 31 and the second light-reflecting surface cooperate to make the infrared radiation energy of the infrared heating element act uniformly on the side surface of the support member 3.

[0058] When the aerosol generating apparatus provided in this application embodiment is used, the aerosol generating substrate 1 is placed into the placement cavity of the support member 3; and infrared light waves are generated by the infrared heating element. Combined with the second light reflecting surface of the radiation flux control cover and the first light reflecting surface 31 of the support member 3, the infrared radiation energy of the infrared heating element is uniformly applied to the side of the support member 3 through the second gap between the side of the support member 3 and the side of the radiation flux control cover, so that the aerosol generating substrate 1 is heated and atomized.

[0059] Since the infrared heating element and the first light reflecting surface 31 of the support 3 have a first gap, the infrared heating element and the support 3 do not contact each other. Therefore, during the process of heating and atomizing the aerosol generating substrate 1, there will be no contact heat conduction between the infrared heating element and the aerosol generating substrate 1 in the support 3, which can achieve complete thermal radiation heating, thereby improving the heating uniformity and thus enhancing the suction experience.

[0060] Specifically, the aerosol generating substrate 1 can be a cigarette or other structure that requires heating and atomization, such as aromatherapy products. This application does not limit the aerosol generating substrate 1.

[0061] Preferably, in the aerosol generating apparatus provided in the above embodiments, the infrared heating element and the support member 3 are arranged coaxially, and the infrared radiation energy of the infrared heating element is uniformly distributed along its circumference. In this embodiment, the axis of the infrared heating element is collinear with the axis of the support member 3, and the infrared radiation intensity of the infrared heating element is uniformly distributed in all radial directions throughout the circumference, that is, the infrared radiation energy of the infrared heating element is isotropic about its axial direction. In this way, the infrared heating element can provide more uniform infrared radiation energy to the second gap between the side of the support member 3 and the side of the radiation flux control cover, further improving the heating uniformity.

[0062] In one specific embodiment of this application, the radiation flux control cover includes a first radiation flux control body 7, which includes a first radiation flux control ring arranged around the outer periphery of the support member 3, the first radiation flux control ring being cylindrical along the axial direction of the support member 3; a second radiation flux control body 6, which includes a second radiation flux control ring arranged around the outer periphery of the infrared heating element, the second radiation flux control ring being sealed and connected to the first radiation flux control ring; wherein, the second light reflecting surface includes the inner wall of the first radiation flux control ring and the inner wall of the second radiation flux control ring.

[0063] In this embodiment, the radiation flux control hood is arranged along the axial direction of the support member 3 (i.e., Figure 1The diagram shows a first radiation flux control body 7 and a second radiation flux control body 6 arranged vertically. The first radiation flux control body 7 has a first radiation flux control ring surrounding the outer periphery of the support member 3, forming a second gap between the first radiation flux control ring and the support member 3 to receive infrared radiation energy. The second radiation flux control body 6 has a second radiation flux control ring surrounding the outer periphery of the infrared heating element, forming a second gap between the second radiation flux control ring and the infrared heating element to receive infrared radiation energy. The inner walls of the first and second radiation flux control rings act as second light reflectors to reflect the infrared radiation generated by the infrared heating element. Simultaneously, the first radiation flux control ring is cylindrical along the axial direction of the support member 3. This ensures a uniform circumferential gap between the inner wall of the first radiation flux control ring and the side of the support member 3, resulting in better uniformity of infrared radiation intensity along the circumferential direction. Consequently, the infrared radiation energy received by the side of the support member 3 is more uniform, improving heating uniformity.

[0064] It is understood that the radiation flux control cover can also adopt other structural forms, such as only including the first radiation flux control body 7, so that the infrared rays of the infrared heating element are directly irradiated into the second gap between the inner wall of the first radiation flux control ring and the side of the support member 3, so as to achieve the same technical effect of making the infrared radiation energy received by the side of the support member 3 uniform. This application will not elaborate on them here.

[0065] To further optimize the above technical solution, the second radiation flux control ring, at least the portion closest to the first radiation flux control ring, gradually narrows from one end closest to the first radiation flux control ring to the other. In this embodiment, the second radiation flux control ring may only gradually expand from the side closest to the first radiation flux control ring to the other, or it may gradually expand entirely from the end furthest from the first radiation flux control ring to the other. Figure 1 As shown, the light-reflecting surface formed on the inner wall of the second radiation flux control ring gradually expands from bottom to top near the bottom end, which enables the infrared radiation flux of the infrared heating element to be evenly distributed and propagated to the second gap between the support 3 and the first radiation flux control ring, preventing the radiation flux from accumulating in the middle of the top of the infrared heating element, resulting in better uniformity of infrared radiation energy.

[0066] In this embodiment, the side of the second radiation flux control ring can also be configured with an inwardly convex target curve. For example... Figure 1 As shown, the light-reflecting surface formed on the inner wall of the second radiation flux control ring has a target curve shape from bottom to top and convex inwards, which can promote the uniform and dispersed upward propagation of infrared radiation flux and prevent the radiation flux from accumulating in the middle position of the top of the infrared heating element. At the same time, the reflective surface has a large area and no reflection dead angle, thereby achieving more uniform infrared radiation between the support 3 and the first radiation flux control ring and improving heating uniformity.

[0067] Preferably, the most convex point of the target curve closest to the axis of the infrared heating element is located near the bottom of the second radiation flux control ring. The second gap between the most convex point and the infrared heating element is minimized, which can reduce the downward propagation of infrared radiation, increase the radiation flux, and thus improve the heating efficiency.

[0068] In a further technical solution, the target curve is a target function curve, and the target function curve and the power function curve are symmetrical with respect to the target straight line L. Specifically, the origin of the coordinate system is a point where the axis of the infrared heating element is aligned with the end of the second radiation flux control loop furthest from the first radiation flux control loop. The radial direction of the infrared heating element is the x-axis, and the axial direction of the infrared heating element is the y-axis. The power function curve satisfies the following condition: y = ax b +c, the first point (r1, 0) and the second point (r2, h) are located at the two ends of the power function curve, and b is the target power; the target line L satisfies the following conditions: Where r1 is the inner diameter of the end of the second radiation flux control ring furthest from the first radiation flux control ring, r2 is the inner diameter of the end of the second radiation flux control ring closest to the first radiation flux control ring, and h is the axial dimension of the second radiation flux control ring.

[0069] In this embodiment, the side curve of the second radiation flux control loop can be plotted about the straight line L-axis using power functions of different powers (e.g., ...). Figure 2 After symmetry along the middle symmetry line shown, rotating it one full turn yields the second radiative flux control ring circumferential surface with varying degrees (e.g., the one shown). Figure 2 The two symmetrical curves on either side of the central symmetry line (one a power function curve, the other a side curve of the second radiative flux control loop) can be used to calculate the distribution of radiative flux through geometric optics simulation. From this, the surface shape that best achieves uniform dispersion of radiative flux at the top of the second radiative flux control loop can be determined. Specifically:

[0070] The second radiant flux control ring is coaxially fitted with the infrared heating element. Based on the dimensions of the infrared heating element, the bottom inner diameter of the second radiant flux control ring can be designed as r1; simultaneously, the inner diameter at the top of the second radiant flux control ring, i.e., at a height h from the bottom, can be designed as r2. Let the power function expression be y = ax. b Given two points (r1, 0) and (r2, h), we can find different power function expressions for different powers of b.

[0071] And given two points (r1, 0) and (r2, h), the expression for line L can be obtained.

[0072] Among them, set By making the power function axially symmetric about the line L, a new spline curve can be obtained. This curve is the side curve of the second radiation flux control loop. Each point on the curve (x... * y * The transformation satisfies:

[0073]

[0074] By rotating the curve to its full circle, the circumferential side surface structure of the second radiation flux control ring can be obtained. Geometric optical simulation calculations are performed on the second radiation flux control rings with different structures to obtain the surface structure with the best uniform diffusion effect.

[0075] In this embodiment, the side of the second radiation flux control ring is convex with an inward-curving objective function curve, resulting in a smoother transition of the light-reflecting surface from top to bottom. This further ensures that the infrared radiation flux propagates upwards in a uniform and dispersed manner, preventing the radiation flux from accumulating at the center of the top of the infrared heating element. Consequently, the infrared radiation between the support member 3 and the first radiation flux control ring is more uniform. Of course, the side of the second radiation flux control ring can also have other curved surface shapes, which will not be listed here.

[0076] To further optimize the above technical solution, the first radiation flux control body 7 also includes a radiation flux control board 71, such as... Figure 1 As shown, the radiation flux control plate 71 is connected between the end of the first radiation flux control ring away from the second radiation flux control ring and the support member 3, and is parallel to the support bottom surface of the support member 3; the second light reflecting surface also includes the inner wall of the radiation flux control plate 71. In this embodiment, the first radiation flux control body 7 is composed of the first radiation flux control ring and the radiation flux control plate 71. By using the circumferential sidewall of the first radiation flux control ring and the inner side surface of the radiation flux control plate 71 as light reflecting surfaces, the dispersion effect of infrared radiation energy is better, and the heating uniformity of the side of the support member 3 is improved.

[0077] Furthermore, the end of the second radiation flux control ring closest to the first radiation flux control ring is flush with or substantially flush with the support bottom surface of the placement cavity. "Substantially flush" means nearly flush, that is, the vertical position difference between the two is very small.

[0078] In this embodiment, the maximum allowable outer diameter of the first radiation flux control ring is used as a constraint, and the overall height of the radiation flux control hood remains unchanged. A structure with different outer diameters of the first radiation flux control ring is set up. At this time, the top position of the second radiation flux control ring will be adjusted accordingly, and geometric optics simulation is performed accordingly. Thus, the final structural optimization result of the radiation flux control hood can be obtained.

[0079] The optimization results show that the top of the second radiation flux control ring is flush with or nearly flush with the supporting bottom surface of the placement cavity. This results in optimal uniformity of radiation flux distributed on the aerosol generating substrate 1, such as the side of the cigarette, and also a relatively consistent distribution of radiation energy in height. Figure 3 As shown, the radiation energy is least in the non-tobacco distribution area at the top, indicating a high energy efficiency.

[0080] To reduce heat dissipation, at least the outer side of the second radiation flux control ring is wrapped with a heat insulation layer 4. This application may wrap the heat insulation layer 4 only on the outer side of the second radiation flux control ring, or it may also wrap the outer side of the first radiation flux control ring with a heat insulation layer 4 to prevent outward heat loss and ensure heating efficiency.

[0081] To simplify the structure, in a specific embodiment, the infrared heating element includes a heating assembly 5, which includes a spiral heating wire 51 extending along its axial direction and an electrode pin 52 electrically connected to the heating wire 51. A radiation flux control cover is placed over the heating assembly 5. A lamp holder 13 is sealed and connected to the radiation flux control cover to form an infrared radiation cavity. The heating assembly 5 is disposed in the lamp slot of the lamp holder 13 and the electrode pin 52 extends out of the lamp holder 13.

[0082] like Figure 1 As shown, the heating assembly 5 is preferably a halogen lamp, mainly composed of a bulb, heating wire 51, connecting wire, molybdenum sheet (not shown in the figure), and electrode pins 52. The heating wire 51 has a vertical spiral shape, which allows it to emit infrared radiation waves uniformly in the radial direction, so that the side of the cigarette receives a uniformly distributed heat radiation flux. The heating wire 51 is a tungsten wire or other wire that can emit infrared light.

[0083] The heating component 5 is placed in the lamp slot of the lamp holder 13, and its electrode pins 52 pass through the opening of the lamp holder 13 to maintain a stable electrical connection with the PCB board below. The second radiant flux control ring is arranged on the outside of the heating component 5 to surround it, and the first radiant flux control body 7 is arranged on top to completely cover the heating component 5.

[0084] The aerosol generating device in this embodiment is based on infrared heating of the heating component 5. The heating element is mainly generated by infrared light waves by the heating component 5. Combined with the relevant radiation flux control cover, the infrared wave radiation can be effectively applied to the side surface of the aerosol generating substrate 1 to achieve heating and atomization of the aerosol generating substrate 1.

[0085] Of course, the heating body of the infrared heating element can also be in other shapes that can provide uniform infrared radiation, such as multiple heating columns arranged in a circumferentially.

[0086] In a further technical solution, the support member 3 is cylindrical, and a light-reflecting film is provided on the outer bottom surface of the support member 3 to form a first light-reflecting surface 31. The light-reflecting film can be an aluminum film or a silver film, which can achieve better light reflection, thereby optimizing the uniformity of infrared radiation energy.

[0087] The support 3 is preferably a glass cup. Glass cups have good light transmittance and temperature resistance, meeting the requirements for smoke heating, and also have high structural mechanical properties, enabling them to effectively support the aerosol generating substrate 1. The top of the first radiation flux control body 7 has an opening through which the glass cup extends. Specifically, both the glass cup and the lamp holder 13 are provided with vent holes 32 to facilitate the flow of atomizing gas. In use, the aerosol generating substrate 1 is placed inside the glass cup, allowing it to fully absorb infrared radiation energy emitted from the heating component 5 and heat up to atomization.

[0088] To improve the fixing reliability of the support member 3, an elastic sleeve 2 is provided on the outer side of the radiation flux control cover to fix the support member 3. The elastic sleeve 2 has a fixing hole for the support member 3 to pass through, and the end of the support member 3 away from the bottom surface has an outer edge that overlaps the outer side of the elastic sleeve 2. Specifically, the elastic sleeve 2 is a silicone sleeve, which is arranged above the top of the first radiation flux control body 7. The glass cup is inserted through the opening of the silicone sleeve to achieve the positioning function of the glass cup. The elastic deformation of the silicone material can effectively fix the glass cup.

[0089] In addition, the second light-reflecting surface of the radiation flux control hood in this application embodiment can be formed by an aluminum-plated film or other light-reflecting film on the inner wall, or it can be formed entirely by aluminum material or other light-reflecting material.

[0090] In general, in one specific embodiment, the aerosol generating device comprises a silicone sleeve, a radiation flux control cover, a glass cup, a heat insulation layer 4, a heating component 5, and a lamp holder 13.

[0091] like Figures 5-7 As shown in the figure, this application embodiment also provides a heated non-combustible atomizing device, including an aerosol generating device for heating and atomizing and an electronic component for supplying power to the aerosol generating device. The electronic component is electrically connected to the aerosol generating device. The aerosol generating device is the aerosol generating device provided in any of the above embodiments, which improves the heating uniformity. The advantage is brought about by the aerosol generating device. For details, please refer to the relevant parts in the above embodiments, which will not be repeated here.

[0092] When the heated non-combustible atomizing device of this application is used, the aerosol generating device is powered by electronic components, and the aerosol generating substrate 1 is heated and atomized by the aerosol generating device.

[0093] Specifically, the aerosol generating substrate 1 can be a cigarette or other structures that require heating and atomization, such as aromatherapy products. When the aerosol generating substrate 1 is a cigarette, the heated non-combustible atomizing device forms a heated non-combustible smoking device in which the cigarette does not come into contact with the heating element during the heating process, achieving complete thermal radiation heating.

[0094] Preferably, the above-mentioned heat-not-burn atomizing device further includes a first conductive element 8, disposed at a position corresponding to the inlet of the support 3; a second conductive element 9, movably disposed radially between the inlet and the first conductive element 8 along the support 3, the second conductive element 9 being able to make electrical contact with the first conductive element 8; and an elastic element, capable of driving the second conductive element 9 to separate from the first conductive element 8, the elastic element being connected to the second conductive element 9; wherein, when the aerosol generating substrate 1 is placed in the placement cavity of the support 3, the aerosol generating substrate 1 is able to drive the second conductive element 9 to move towards the first conductive element 8 and make the first conductive element 8 and the second conductive element 9 make electrical contact; one of the first conductive element 8 and the second conductive element 9 is electrically connected to the positive electrode of the electronic component, and the other is electrically connected to the negative electrode of the electronic component.

[0095] like Figure 5 and Figure 7 As shown, the aerosol generating device is installed inside the top of the outer shell 11 of the heated non-combustible atomizing device, supported by a bracket 10 inside the outer shell 11. The first conductive element 8, the second conductive element 9, and the elastic element form a circuit breaker protection assembly, which is positioned between the top of the aerosol generating device and the top cover 12 of the outer shell 11 and is limited and fixed by the bracket 10, thus realizing the circuit breaker protection function of the entire device. Specifically, the first conductive element 8 and the second conductive element 9 are both columnar, i.e., rod-shaped; the elastic element is a spring, which is sleeved on the second conductive element 9; the first conductive element 8 and the second conductive element 9 are respectively connected to the positive and negative terminals of the electronic component output.

[0096] When no cigarette is inserted into the heated tobacco atomizer, the second conductive element 9 extends above the inlet of the support member 3 under the action of the spring, preventing it from contacting the first conductive element 8 and thus creating an open circuit in the system. When a cigarette is inserted into the heated tobacco atomizer, the cigarette structure compresses the spring through the second conductive element 9, causing the second conductive element 9 to move out of the inlet and contact the first conductive element 8, thus establishing an electrical connection in the system. This ensures that the device cannot be started when no cigarette is inserted, preventing infrared radiation leakage and improving safety.
