Description

Technical Field

[0002] This application relates to the technical field of atomization, and more specifically, to an atomization device.

Background Art

[0003] An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium. Since an aerosol is absorbed by the human body through the respiratory system, it provides users with a new alternative absorption method. For example, by applying an atomization device for an aerosol that generates an aerosol generation substrate such as a medical drug to different fields such as medical treatment, and transporting an inhalable aerosol to users, it can replace the normal product form and absorption method.

[0004] Currently, the atomization device heats the entire atomization cartridge provided with an aerosol generation substrate. Since the atomization cartridge needs to absorb a large amount of energy, it not only reduces the energy utilization rate but also restricts the time for aerosol generation. Furthermore, the conduction heating method makes the temperature distribution inside the atomization cartridge extremely uneven, further affecting the suction texture and consistency.

[0026] Referring to Figures 1 to 4, one embodiment of the present invention provides an atomizer 100, which includes a main housing 110, a suction port 120, an aerosol generating substrate box 130, a power supply module 150, a drive module 180, a heating module 170, and a control unit. The suction port 120 is attached to one end of the main housing 110 and extends from the main housing 110, the power supply module 150, the heating module 170, the drive module 180, and the control unit are all mounted inside the main housing 110, the aerosol generating substrate box 130 is removably mounted inside the main housing 110 and houses an aerosol generating substrate 132 and a transmission mechanism (133 / 134 / 135) inside the aerosol generating substrate box 130.

[0027] Under the control of the control unit, the drive module 180 drives the transmission mechanism (133 / 134 / 135) in the aerosol generating substrate box 130 to release the aerosol generating substrate 132, causing the aerosol generating substrate 132 to move along a predetermined path, and the heating module 170 is positioned along the path of the aerosol generating substrate 132. The electrical energy from the power supply module 150 heats the released aerosol generating substrate 132, causing it to atomize and form an aerosol, which flows out through the inhalation port 120 and is inhaled by the user.

[0028] The main housing 110 has a hollow cubic housing structure and includes a housing bottom wall 112, a housing side wall 114 formed extending in the same direction from the edge of the housing bottom wall 112, and a housing top wall 116 provided on the side of the housing side wall 114 away from the housing bottom wall 112. The housing bottom wall 112, housing side wall 114, and housing top wall 116 together enclose a housing cavity 118 for housing components such as an aerosol-generating substrate box 130. In the following embodiment, the length direction of the main housing 110 is the first direction (i.e., the X direction in Figure 2), the width direction of the main housing 110 is the second direction (i.e., the Y direction in Figure 2), and the thickness direction of the main housing 110 is the third direction (i.e., the Z direction in Figure 2). As can be understood, the shape of the main housing 110 is not limited thereto, and in some other embodiments, the main housing 110 may have different shapes such as columnar or tower-like to meet different requirements.

[0029] The aerosol-generating substrate box 130 is removably housed in a storage cavity 118 and includes a main housing 131, an aerosol-generating substrate 132, and a transmission mechanism (133 / 134 / 135). The strip-shaped or sheet-shaped aerosol-generating substrate 132 is stored in the main housing 131 in a form such as being wrapped, folded, or stacked, and the transmission mechanism (133 / 134 / 135) is controlled by a drive module 180 to release the aerosol-generating substrate 132, causing the heating element 174 to sequentially heat different regions of the aerosol-generating substrate 132.

[0030] As shown in Figures 2 to 5, the main housing 131 has a hollow cubic housing structure, with the length of the main housing 131 extending along a first direction, the width of the main housing 131 extending along a second direction, and the thickness of the main housing 131 extending along a third direction. To be understood, the shape of the main housing 131 is not limited to this, and the shape of the main housing 131 can be adapted to the shape of the main housing 110 to meet different requirements.

[0031] The main enclosure 131 is provided with a storage cavity 1312 and a recovery cavity 1314 that are independent of each other. The storage cavity 1312 stores the aerosol-generating substrate 132 that has not been released, and the recovery cavity 1314 stores the atomized aerosol-generating substrate 132. In this way, the aerosol-generating substrate 132 in the storage cavity 1312 is gradually transferred to the recovery cavity 1314 by the transfer mechanism (133 / 134 / 135), and the heating member 174 can heat the aerosol-generating substrate 132 during the transfer process.

[0032] Specifically, in one embodiment, the storage cavity 1312 and the recovery cavity 1314 are spaced apart in the longitudinal direction of the main housing 131, thereby reducing the dimensions of the main housing 131 in the width and thickness directions. As can be understood, the positional relationship between the storage cavity 1312 and the recovery cavity 1314 is not limited, and in some other embodiments, the storage cavity 1312 and the recovery cavity 1314 may be spaced apart in the width direction of the main housing 131, and in some other embodiments, the storage cavity 1312 and the recovery cavity 1314 may communicate with each other to simplify the housing structure. In a preferred embodiment, to prevent the aerosol-generating substrate 132 in the storage cavity 1312 from being altered by moisture, a material or element with drying properties, such as a desiccant, can be placed in the storage cavity 1312 to absorb moisture from the air and ensure that the internal environment of the storage cavity 1312 is dry.

[0033] For the convenience of heating the aerosol-generating substrate 132 by the heating element 174, a heating groove 1316 is provided at one end of the main housing 131. The storage cavity 1312 and the recovery cavity 1314 are located on opposite sides of the heating groove 1316 in the second direction. The storage cavity 1312 and the recovery cavity 1314 are both connected to the external environment of the main housing 131 by the heating groove 1316, and the heating groove 1316 is located in the movement path of the aerosol-generating substrate 132. In this way, the aerosol-generating substrate 132 released from the storage cavity 1312 enters the recovery cavity 1314 through the heating groove 1316, and one end of the heating element 174 enters the heating groove 1316 along the third direction, heating the aerosol-generating substrate 132 located within the heating groove 1316. To make it easier to understand, both the storage cavity 1312 and the recovery cavity 1314 may have openings that communicate with each other and the heating groove 1316 made as small as possible, and a shielding structure such as a curtain may be provided to prevent aerosols in the heating groove 1316 from entering the storage cavity 1312 and the recovery cavity 1314.

[0034] Furthermore, an atomizing sealing member 160 is provided within the main housing 110. The atomizing sealing member 160 is positioned and connected to one end of the main housing 131 where the heating groove 1316 is located, and is positioned outside the heating groove 1316, thereby defining and forming an atomizing cavity that connects the heating groove 1316 and the intake port 120. An intake hole is provided in the atomizing sealing member 160 that connects the atomizing cavity to the external environment. In this way, external airflow flows into the atomizing cavity through the intake hole, and the aerosol generated by the atomization of the aerosol-generating substrate 132 can flow into the intake port 120 along with the airflow.

[0035] As shown in Figures 5 and 8, the aerosol-generating substrate 132 is in the form of a strip or a sheet. Specifically, the strip-shaped aerosol-generating substrate 132 may be wound one layer at a time along the circumferential direction to form a substrate winding and stored in the main housing 131, or it may be folded back and forth along the linear direction to form a substrate bundle and stored in the main housing 131. The sheet-shaped aerosol-generating substrate 132 may be stacked one layer at a time along the linear direction to form a substrate bundle and stored in the main housing 131. To make it clear, the storage form of the aerosol-generating substrate 132 is not limited, and different shapes may be formed by different winding and folding forms as needed.

[0036] Preferably, the aerosol-generating substrate 132 has a thickness of 0.1 mm to 0.8 mm and a width of 3 mm to 10 mm, and the heating element 174 can sequentially heat each part of the aerosol-generating substrate 132. Compared to columnar aerosol-generating substrates in the prior art, the thickness of the sheet-shaped and strip-shaped aerosol-generating substrate 132 is extremely small. Therefore, during the heating process, the temperature rise is uniform and the heating rate is fast. The overflow path of the aerosol generated when the aerosol-generating substrate 132 is heated and atomized is short, eliminating the need for preheating. To make it clear, the specific dimensions of the thickness and width of the aerosol-generating substrate 132 are not limited and may be set as needed to meet different requirements.

[0037] The aerosol-generating substrate 132 is prepared as a slurry by mixing one or more of the following: tobacco leaves, expanded tobacco stems, tobacco particles, tea leaves, and mint leaves; one or more of the following: a smoke-generating agent, propylene glycol, glycerin, or other polyols; and materials such as an essence fragrance. Therefore, when heated, it can be atomized to produce an aerosol that can be inhaled by a person. To understand this, the materials forming the aerosol-generating substrate 132 are not limited to these and may be set as needed to satisfy different requirements.

[0038] In some embodiments, electromagnetic heating units are further uniformly distributed within the aerosol-generating substrate 132, and these electromagnetic heating units can generate an electric current induced by the magnetic field generated by the heating element 174. As a result, the charges on them move rapidly and irregularly, colliding and rubbing together to generate thermal energy and heat the aerosol-generating substrate 132. Specifically, the electromagnetic heating units are formed from one or more ferromagnetic materials, such as iron, cobalt, nickel and its alloys, and rare earth elements and their alloys, and the form of the electromagnetic heating units may be one or more of particulate, powdery, fibrous, or cotton-like.

[0039] In some embodiments, the aerosol-generating substrate 132 includes at least one atomizing layer 1322 and at least one support layer 1323, where the atomizing layer 1322 and the support layer 1323 are alternately stacked in the thickness direction, and the support layer 1323 provides support to the atomizing layer 1322, improving the tensile and shear resistance of the aerosol-generating substrate 132. In addition, the atomizing layer 1322 between two support layers 1323 is defined as one atomizing layer 1322.

[0040] Referring to Figure 9, specifically, in one embodiment, the aerosol-generating substrate 132 includes one atomizing layer 1322 and one support layer 1323, with the support layer 1323 located above or below the atomizing layer 1322. Specifically, in another embodiment, the aerosol-generating substrate 132 includes two atomizing layers 1322 and one support layer 1323, with the support layer 1323 located between the two atomizing layers 1322. As can be understood, the number of atomizing layers 1322 and support layers 1323 is not limited and can be set as needed.

[0041] Furthermore, the support layer 1323 may be formed from one or more metallic materials, such as gold, silver, copper, iron, tin, zinc, nickel, aluminum, tungsten, molybdenum, tantalum, niobium, titanium, nickel groups, cobalt groups, steel and stainless steel metals and their alloy foils, or from one or more heat-resistant non-metallic film strips, such as glass fiber, Teflon, and polyimide. The thickness of the support layer 1323 is preferably 0.01 mm to 0.15 mm, and the width of the support layer 1323 may be equal to the width of the atomizing layer 1322, or it may be smaller or larger than the width of the atomizing layer 1322. In this way, the support layer 1323 has superior mechanical performance compared to the atomizing layer 1322, thereby improving the tensile and shear resistance of the aerosol-generating substrate 132, and furthermore, the support layer 1323 can transfer heat. This allows for preheating of areas not in contact with the heating sheet, further improving the uniformity of heating.

[0042] Furthermore, the support layer 1323 has connecting holes 1323a that penetrate it along the thickness direction, and multiple connecting holes 1323a are arranged in an array in at least a portion of the area of ​​the support layer 1323, and the connecting holes 1323a allow the aerosol to flow from the atomizing layer 1322 where it is currently located to an adjacent atomizing layer 1322 or to the outside. In order to ensure that the aerosol has a sufficiently high overflow rate, the porosity of the support layer 1323 (i.e., the ratio of the total area of ​​connecting holes 1323a per unit area to the unit area) is 30% or more. Specifically, when the aerosol generating substrate 132 includes one atomizing layer 1322 and one support layer 1323, the support layer 1323 is located on the upper or lower surface of the atomizing layer 1322, and the aerosol generated by the atomization of the atomizing layer 1322 flows out through the connecting holes 1323a opened in the support layer 1323. If the aerosol-generating substrate 132 includes two atomizing layers 1322 and one support layer 1323, and the support layer 1323 is located between the two atomizing layers 1322, then the aerosol generated by the atomization of one of the atomizing layers 1322 can flow through the communication holes 1323a opened in the support layer 1323 to the other atomizing layer 1323.

[0043] Referring to Figure 6, in the first embodiment of the present invention, the aerosol-generating substrate box 130 includes a transmission mechanism 133 for releasing the aerosol-generating substrate 132, the transmission mechanism 133 includes a release center roller 1332 and a transmission module 1334. The release center roller 1332 is rotatably mounted in the storage cavity 1312, the central axis of the release center roller 1332 extends along a third direction, and one end of the strip-shaped aerosol-generating substrate 132 is wrapped around the release center roller 1332. The transmission module 1334 is located between the storage cavity 1312 and the recovery cavity 1314, and is on the side of the heating groove 1316 that is close to the recovery cavity 1314. The transmission module 1334 applies a tensile force to one end of the aerosol-generating substrate 132, causing different regions of the aerosol-generating substrate 132 to sequentially enter the heating groove 1316, and also drives the discharge center roller 1332 to rotate and discharge the aerosol-generating substrate 132 synchronously.

[0044] Specifically, the transmission module 1334 includes two spaced transmission rollers 1334a, which are rotatably mounted on the main housing 131, and the central axes of the two transmission rollers 1334a extend along a third direction. A clamping gap is defined and formed between the two transmission rollers 1334a for the aerosol-generating substrate 132 to pass through, and the drive module 180 is electrically connected to one of the transmission rollers 1334a to drive and rotate it. As a result, the aerosol-generating substrate 132 located within the clamping gap continues to move forward due to the rotational action of the transmission rollers 1334a and enters the recovery cavity 1314 via the heating groove 1316.

[0045] Referring to Figure 5, in a second embodiment of the present invention, the aerosol generation box includes a transmission mechanism 134 for releasing an aerosol-generating substrate 132, the transmission mechanism 134 includes a release center roller 1341 and a transmission module, the transmission module includes a recovery center roller 1343. The release center roller 1341 is rotatably mounted in a storage cavity 1312, and the central axis of the release center roller 1341 extends along a third direction, and the recovery center roller 1343 is rotatably mounted in a recovery cavity 1314, and the central axis of the recovery center roller 1343 extends along a third direction. The front and rear ends of the aerosol-generating substrate 132 are wound around the release center roller 1341 and the recovery center roller 1343, respectively. The drive module 180 is dynamically connected to the recovery center roller 1343, which rotates under the drive of the drive module 180 to recover the aerosol-generating substrate 132. The aerosol-generating substrate 132, moving under the drive of the recovery center roller 1343, rotates synchronously with the release center roller 1341, thereby releasing the aerosol-generating substrate 132 synchronously. Furthermore, in some embodiments, the transmission module further includes a plurality of intermediate pulleys, each intermediate pulley located at a different position within the main housing 131, thereby restricting the movement path of the aerosol-generating substrate 132.

[0046] Referring to Figures 7 and 8, in a third embodiment of the present application, the aerosol-generating substrate 132 is in the form of a sheet or a strip folded reciprocally along one direction, and the aerosol-generating substrate box 130 includes a transmission mechanism 135 for releasing the aerosol-generating substrate 132, the transmission mechanism 135 includes a feed pickup roller 1352 and a transport roller module 1354. The feed pickup roller 1352 and the transport roller module 1354 are spaced apart and located on opposite sides of the heating groove 1316 in a second direction, and the feed pickup roller 1352 is located above the storage cavity 1312, with the central axis of the feed pickup roller 1352 extending along a third direction. The transport roller module 1354 includes two transport rollers 1354a spaced apart in a first direction, with the central axes of the transport rollers 1354a extending along a third direction, and a transport gap is formed between the two transport rollers 1354a. The drive module 180 is dynamically connected to the feed pickup roller 1352 and one of its transport rollers 1354a, thereby driving and rotating the feed pickup roller 1352 and the transport roller 1354a, respectively.

[0047] In this manner, the feed pickup roller 1352, driven by the drive module 180, applies a forward force to the aerosol-generating substrate 132. One end of the aerosol-generating substrate 132 is released by the push of the feed pickup roller 1352 and enters the heating groove 1316. It then enters the transport gap formed by the transport roller module 1354 and moves to the recovery cavity 1314 due to the rotational action of the transport roller 1354a.

[0048] Furthermore, in the third embodiment, the aerosol generating substrate box 130 further includes a lifting mechanism 136, which pushes the aerosol generating substrate 132 closer to the feeding pickup roller 1352, thereby sequentially bringing each sheet or stage of aerosol generating substrate 132 into contact with the feeding pickup roller 1352, and further causes it to enter the heating groove 1316 by being pushed by the feeding pickup roller 1352.

[0049] Specifically, the lifting mechanism 136 is located within the storage cavity 1312 and includes a lifting base 1361 and a lifting drive member 1363. The aerosol-generating substrate 132 is for which the aerosol-generating substrate 132 is placed, and the lifting drive member 1363 moves the lifting base 1361 in a first direction, thereby ensuring that the aerosol-generating substrate 132 is always in contact with the feed pickup roller 1352. In a preferred embodiment, the lifting drive member 1363 is an elastic member extending along the first direction, and the lifting drive member 1363 can apply a tensile force toward the feed pickup roller 1352 relative to the lifting base 1361. As can be understood, the specific structure of the lifting drive member 1363 is not limited, and in some other embodiments, the lifting drive member 1363 may be a drive structure such as a screw.

[0050] In some embodiments, the aerosol-generating substrate box 130 further includes a grinding mechanism (not shown) located within the recovery cavity 1314, which applies force to the aerosol-generating substrate 132 in the recovery cavity 1314 to grind the released aerosol-generating substrate 132. As can be understood, the specific structure of the grinding mechanism is not limited, as long as it can perform grinding of the aerosol-generating substrate 132. In some other embodiments, a further pressing structure may be provided within the recovery cavity 1314 to reduce the volume of the recovery cavity 1314 by pressing the recovered aerosol-generating substrate 132, thereby reducing its spatial occupancy and ultimately contributing to a smaller volume for the atomizer 100.

[0051] Referring again to Figures 2 to 5, in some embodiments, a mounting column 1141 is provided on the surface of the main housing 110 away from the storage cavity 118, communicating with the atomizing cavity. One end of a columnar suction port 120 is inserted into the mounting column 1141, and the other end of the suction port 120 extends in a direction away from the top wall 116 of the housing along the third direction. In this way, the aerosol generated by the aerosol-generating substrate 132 in the aerosol-generating substrate box 130 can flow out through the suction port 120.

[0052] The power supply module 150 is located on the side of the mounting cavity in the second direction, and the heating module 170 is located on the side of the power supply module 150 in the first direction. The heating module 170 includes a heating mounting case 172 and a heating element 174. The heating mounting case 172 is positioned and connected to the main housing 131, one end of the heating element 174 is positioned within the main housing 131 and electrically connected to the power supply module 150, and the other end of the heating element 174 enters into the heating groove 1316 along the third direction to heat the aerosol generating substrate 132.

[0053] Specifically, in some embodiments, the heating element 174 is arranged as a resistance heater, an electromagnetic induction heater, or a plasma heater, and the heating element 174 is in close contact with the aerosol-generating substrate and conducts heat to the aerosol-generating substrate. Specifically, in some embodiments, the heating element 174 heats the aerosol-generating substrate 132 using a conduction heating method, and the heating element 174 is a flat heating sheet, an arc-shaped heating sheet, or a heating block that can generate heat after being energized, and the heating element 174 enters the heating groove 1316 and comes into direct contact with the aerosol-generating substrate 132, thereby heating the aerosol-generating substrate 132 by conduction heating.

[0054] In some other embodiments, an electromagnetic heating unit is placed within the aerosol-generating substrate 132, and the heating element 174 is an electromagnetic heating coil, which is positioned in a heating groove 1316 and spaced apart from the aerosol-generating substrate 132, and the heating element 174 can generate an alternating magnetic field after being energized. This excites the aerosol-generating substrate 132, generating an alternating current, which generates heat and atomizes it. Preferably, the distance between the heating element 174 and the aerosol-generating substrate 132 is 0.5 mm to 2.0 mm.

[0055] In some other embodiments, the heating module 170 is arranged as a microwave heating device or an infrared radiation heating device, and the heating module 170 approaches the aerosol-generating substrate and conducts microwave or infrared radiation to the aerosol-generating substrate.

[0056] The drive module 180 is located on the second side of the mounting cavity of the power supply module 150, and the drive module 180 includes a drive motor, which is electrically connected to the transmission mechanism (133 / 134 / 135) to drive the transmission mechanism (133 / 134 / 135) to release and recover the aerosol generating substrate 132.

[0057] In some embodiments, the atomizer 100 further includes a feed detection module 190 communicably connected to a control unit, which controls the operating state of the drive module 180 by obtaining the release length of the aerosol-generating substrate 132, and further causes the transmission mechanism (133 / 134 / 135) to periodically release the aerosol-generating substrate 132. That is, the control unit controls the transmission mechanism (133 / 134 / 135) to release the aerosol-generating substrate 132 at predetermined timings and in predetermined amounts, thereby ensuring that the aerosol-generating substrate 132 in the heating groove 1316 is updated in a timely manner, maximizing energy utilization, and avoiding overheating of the aerosol-generating substrate 132. Preferably, the release length of each period is greater than or equal to the length of the heating groove 1316, thereby avoiding repeated heating of already heated portions.

[0058] Specifically, a detection groove 1318 is provided at one end of the main housing 131 of the aerosol-generating substrate box 130, where a heating groove 1316 is located, connecting the storage cavity 1312 and the heating groove 1316. The aerosol-generating substrate 132 released from the storage cavity 1312 is detected by the detection groove 1318 and then enters the heating groove 1316 for heating. The feeding detection module 190 includes a detection rotating shaft 192, a pinch roller 194, and a detection unit 198. The detection rotating shaft 192 enters the detection groove 1318 along a third direction and is in close contact with one side surface of the aerosol-generating substrate 132, and the detection rotating shaft 192 can rotate along with the moving aerosol-generating substrate 132. The pinch roller 194 is located on one side of the detection rotation shaft 192 in the first direction, and the pinch roller 194 applies pressure to the aerosol-generating substrate 132 to ensure that the aerosol-generating substrate 132 is in close contact with the detection rotation shaft 192. The feeding detection unit 198 is connected to the detection rotation shaft 192 and is located outside the main housing 131, and the feeding detection unit 198 detects the rotation angle of the rotation shaft 192 to obtain the release length of the aerosol-generating substrate 132, and further feeds back a control signal to the drive module 180 to control the operating state of the drive module 180.

[0059] Furthermore, the detection module further includes a pinch roller holder 196, one end of which is positioned and connected to a pinch roller 194, and the other end of which is positioned and connected to the outside of the main housing 110, allowing the user to conveniently replace the aerosol generation box or aerosol generation substrate 132 by pushing the pinch roller holder 196 along a first direction to adjust the gap between the pinch roller 194 and the detection rotation shaft 192.

[0060] To ensure understanding, the detection method of the feeding detection module 190 is not limited to this, and in some other embodiments, the feeding detection module 190 can also control the operating state of the drive module 180 by detecting the rotational speed of the drive motor of the drive module 180. In some other embodiments, detection marks are provided at intervals along the length of the aerosol-generating substrate 132, and the detection marks are formed by mechanical structural features, optical features or magnetic features, and the feeding detection module 190 can obtain the release length of the aerosol-generating substrate 132 by detecting the number of detection marks. Specifically, in one embodiment, if a support layer 1323 is provided on the aerosol-generating substrate 132, the release length of the aerosol-generating substrate 132 may be obtained by detecting the number of metering holes passing through the feeding detection module 190, by providing metering holes at intervals along the length of the support layer 1323 on opposing sides in the width direction.

[0061] In some embodiments, the atomizer 100 further includes a remaining amount detection unit 198 communicably connected to a control unit, which detects the remaining amount of the unreleased portion of the aerosol-generating substrate 132 to prompt the user to inspect or replace the aerosol-generating substrate box 130 or the aerosol-generating substrate 132 in a timely manner. Specifically, the remaining amount detection unit 198 can obtain the remaining amount of the aerosol-generating substrate 132 in the storage cavity 1312 by detecting changes in the motor clogging current of the drive module 180 or changes in the temperature curve of the heating element 174, and feed this back to the control unit, thereby prompting the user to inspect or replace the aerosol-generating substrate box 130 by outputting, but not limited to, displays, vibrations, and sounds.

[0062] In some embodiments, the atomizing device 100 is further equipped with a sensor that is communicably connected to a control unit. The sensor is used to provide the user with information on the usage status of the atomizing device 100 by acquiring the number of inhalations and the usage time.

[0063] In some embodiments, a mounting detection unit 198 is provided in the main housing 110, and a sensing element 137 corresponding to the mounting detection unit 198 is provided in the aerosol generation substrate box 130. The mounting detection unit 198 can detect the sensing element 137 to determine whether or not the aerosol generation substrate box 130 is present in the mounting cavity. Specifically, the mounting detection unit 198 includes, but is not limited to, a Hall sensor and a photoelectric sensor, and the sensing element 137 includes, but is not limited to, a magnetic element corresponding to the Hall sensor or a light-shielding plate corresponding to the photoelectric sensor. The Hall sensor can determine whether or not the aerosol generation substrate box 130 is present in the mounting cavity by detecting whether or not a magnetic element is present. The photoelectric sensor can determine whether or not the aerosol generation substrate box 130 is present in the mounting cavity by detecting whether or not a light-shielding plate is present.

[0064] In the atomizing device 100 described above, different regions of the strip-shaped or sheet-shaped aerosol-generating substrate 132 are sequentially heated by the heating element 174. Since the thickness of the aerosol-generating substrate 132 decreases with each heating, the heating rate is fast, the aerosol overflow time is short, and different regions of the aerosol-generating substrate 132 can be heated uniformly. As a result, it has a high energy utilization rate and high consistency in texture.

[0065] The technical features of the embodiments described above can be combined in any way, and for the sake of brevity, not all possible combinations of the technical features in the embodiments described above have been explained. However, these combinations of technical features should be considered to be within the scope described herein, as long as they do not contradict each other.

[0066] The embodiments described above merely illustrate some embodiments of the present application, and although their descriptions are relatively specific and detailed, they should not be understood as limiting the scope of the claims. Those skilled in the art can make various modifications and improvements without departing from the concept of the present application, and all of these fall within the scope of protection. Therefore, the scope of protection of the present application is as defined in the attached claims. [Explanation of Symbols]
