Description

Technical Field

[0001] The present invention relates to the field of atomization technology, in particular to an atomization device. Background Art

[0002] Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium. Since aerosol can be absorbed by the human body through the respiratory system, it provides users with a new alternative absorption method. For example, atomization devices that generate aerosols from aerosol-generating matrices such as medical drugs can be used in different fields such as medicine to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] Currently, atomizers require heating the entire cartridge, which houses the aerosol-generating matrix. This requires the cartridge to absorb a significant amount of energy, reducing energy utilization and limiting the time required for aerosol generation. Furthermore, the conductive heating method results in extremely uneven temperature distribution within the cartridge, further impacting the flavor and consistency of the puff. Summary of the Invention

[0004] Based on this, it is necessary to provide an atomizing device to address the problems of low energy utilization and uneven temperature distribution of atomizing bullets, which can achieve the technical effects of increasing energy utilization and improving temperature distribution uniformity.

[0005] According to one aspect of the present application, there is provided an atomizing device, comprising:

[0006] A main housing having a receiving cavity;

[0007] An aerosol generating matrix cartridge is detachably received in the accommodating chamber. The aerosol generating matrix cartridge comprises a main box body and an aerosol generating matrix received in the main box body. The aerosol generating matrix is ​​in the form of a strip or sheet. The aerosol generating matrix is ​​configured to move relative to the main box body along a preset path.

[0008] The heating component is arranged in the accommodating cavity and is located on the moving path of the aerosol generating substrate.

[0009] In one embodiment, the aerosol generating substrate is detachably housed in the main box.

[0010] In one embodiment, the aerosol-generating matrix box includes a conveying mechanism, and the atomizing device includes a driving assembly that is transmission-connected to the conveying mechanism. The conveying mechanism releases the aerosol-generating matrix under the drive of the driving assembly, so that different areas of the aerosol-generating matrix pass through the heating assembly in sequence.

[0011] In one embodiment, the main box body is provided with a heating groove, the heating groove is located on the movement path of the aerosol, and the heating component is partially located in the heating groove.

[0012] In one embodiment, the atomization device further includes a feeding detection component, which is used to obtain the release length of the aerosol generating substrate, and the driving component drives the conveying mechanism to release the aerosol generating substrate according to the release length.

[0013] In one embodiment, the feed detection assembly includes a detection shaft and a detection unit. The detection shaft is attached to one side of the aerosol generating matrix and rotates driven by the aerosol generating matrix. The feed detection unit is used to detect the rotation angle of the shaft to obtain the release length of the aerosol generating matrix.

[0014] In one embodiment, the heating assembly includes a heating element, which is configured as a resistance heater, an electromagnetic induction heater, or a plasma heater, and the heating element is attached to the aerosol generating substrate to conduct heat to the aerosol generating substrate; or

[0015] The heating component is configured as a microwave heating device or an infrared radiation heating device, and the heating component is adjacent to the aerosol-generating substrate to conduct microwaves or infrared radiation to the aerosol-generating substrate.

[0016] In one embodiment, the heating component includes an electromagnetic heating coil, and electromagnetic heating units are evenly distributed in the aerosol generating matrix. The aerosol generating matrix can sense the magnetic field generated by the electromagnetic heating coil and generate current.

[0017] In one embodiment, the atomization device further comprises a residual amount detection unit, and the residual amount detection unit is used to detect the residual amount of the unreleased portion of the aerosol generating matrix.

[0018] In one embodiment, the main housing is provided with an installation detection unit, and the installation detection unit is used to detect whether the aerosol generating matrix box is present in the accommodating cavity.

[0019] In one embodiment, the aerosol generating matrix cartridge is provided with a sensing element, and the installation detection unit is capable of detecting the sensing element to determine whether the aerosol generating matrix cartridge is present in the accommodating cavity.

[0020] In the above-mentioned atomization device, the heating component can directly heat the sheet-shaped or strip-shaped aerosol generating substrate passing through it, thereby having a higher energy utilization rate. Moreover, since the thickness of the sheet-shaped and strip-shaped aerosol generating substrate is very small, the temperature rises evenly and quickly during the heating process. The overflow path of the aerosol generated by the heated and atomized aerosol generating substrate is short, and no preheating is required. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] See Figures 1 to 4 One embodiment of the present invention provides an atomizing device 100, which includes a main housing 110, a nozzle 120, an aerosol-generating matrix cartridge 130, a power supply assembly 150, a drive assembly 180, a heating assembly 170, and a control unit. The nozzle 120 is mounted on one end of the main housing 110 and extends out of the main housing 110. The power supply assembly 150, the heating assembly 170, the drive assembly 180, and the control unit are all mounted within the main housing 110. The aerosol-generating matrix cartridge 130 is detachably mounted within the main housing 110. The aerosol-generating matrix cartridge 130 contains an aerosol-generating matrix 132 and a conveying mechanism (133, 134, 135).

[0039] Under the control of the control unit, the drive assembly 180 drives the conveying mechanism (133, 134, and 135) within the aerosol-generating substrate cartridge 130 to release the aerosol-generating substrate 132, causing the aerosol-generating substrate 132 to move along a predetermined path. The heating assembly 170 is located along the path of the aerosol-generating substrate 132. The released aerosol-generating substrate 132 is heated by electrical energy from the power supply assembly 150, atomizing the aerosol-generating substrate 132 to form an aerosol. The aerosol then flows out through the mouthpiece 120 for inhalation by the user.

[0040] The main housing 110 is a hollow cubical housing structure, comprising a housing bottom wall 112, housing side walls 114 extending in the same direction from the edge of the housing bottom wall 112, and a housing top wall 116 located on the side of the housing side wall 114 away from the housing bottom wall 112. The housing bottom wall 112, the housing side walls 114, and the housing top wall 116 together enclose a receiving cavity 118 for receiving structures such as the aerosol generating matrix box 130. In the following embodiments, the length direction of the main housing 110 is the first direction (i.e., Figure 2 The width direction of the main housing 110 is the second direction (ie Figure 2 The thickness direction of the main housing 110 is the third direction (ie Figure 2 It will be appreciated that the shape of the main housing 110 is not limited thereto. In other embodiments, the main housing 110 may be in a columnar, tower-like, or other different shapes to meet different requirements.

[0041] The aerosol-generating substrate cartridge 130 is removably housed within the housing chamber 118 and includes a main cartridge body 131, an aerosol-generating substrate 132, and a conveying mechanism (133, 134, 135). The strip-shaped or sheet-shaped aerosol-generating substrate 132 is stored in the main cartridge body 131 in a coiled, folded, or stacked manner. Driven by the drive assembly 180, the conveying mechanism (133, 134, 135) controls the release of the aerosol-generating substrate 132, allowing the heating element 174 to sequentially heat different regions of the aerosol-generating substrate 132.

[0042] like Figures 2 to 5 As shown, the main box body 131 has a hollow, cubical shell structure. The length of the main box body 131 extends along a first direction, the width of the main box body 131 extends along a second direction, and the thickness of the main box body 131 extends along a third direction. It is understood that the shape of the main box body 131 is not limited to this, and the shape of the main box body 131 can be adapted to the shape of the main shell 110 to meet different requirements.

[0043] The main box body 131 is provided with a mutually independent storage chamber 1312 and recovery chamber 1314. The storage chamber 1312 is used to store unreleased aerosol-generating substrate 132, while the recovery chamber 1314 is used to store atomized aerosol-generating substrate 132. Thus, the aerosol-generating substrate 132 in the storage chamber 1312 is gradually transferred to the recovery chamber 1314 via the transfer mechanism (133, 134, and 135). The heating element 174 can heat the aerosol-generating substrate 132 during the transfer process.

[0044] Specifically, in one embodiment, the storage chamber 1312 and the recovery chamber 1314 are spaced apart along the length of the main box body 131 to reduce the width and thickness of the main box body 131. It is understood that the positional relationship between the storage chamber 1312 and the recovery chamber 1314 is not limited. In other embodiments, the storage chamber 1312 and the recovery chamber 1314 may be spaced apart along the width of the main box body 131. In other embodiments, the storage chamber 1312 and the recovery chamber 1314 may be interconnected to simplify the box structure. As a preferred embodiment, to prevent the aerosol-generating matrix 132 in the storage chamber 1312 from becoming damp and deteriorating, a desiccant or other drying material or component may be placed in the storage chamber 1312 to absorb moisture from the air and ensure a dry environment within the storage chamber 1312.

[0045] To facilitate heating of the aerosol-generating substrate 132 by the heating element 174, a heating groove 1316 is provided at one end of the main body 131. The storage chamber 1312 and the recovery chamber 1314 are located on opposite sides of the heating groove 1316 in the second direction. The storage chamber 1312 and the recovery chamber 1314 are connected to the external environment of the main body 131 through the heating groove 1316. The heating groove 1316 is located in the movement path of the aerosol-generating substrate 132. Thus, the aerosol-generating substrate 132 released from the storage chamber 1312 passes through the heating groove 1316 and enters the recovery chamber 1314. One end of the heating element 174 extends into the heating groove 1316 along the third direction to heat the aerosol-generating substrate 132 within the heating groove 1316. It can be understood that the openings connecting the storage chamber 1312 and the recovery chamber 1314 with the heating tank 1316 are as small as possible, and a shielding structure such as a curtain can be set to prevent the aerosol in the heating tank 1316 from entering the storage chamber 1312 and the recovery chamber 1314.

[0046] Furthermore, an atomizing seal 160 is disposed within the main housing 110. This seal 160 is attached to one end of the main cartridge 131 where the heating groove 1316 is located, so as to cover the heating groove 1316. This defines an atomizing chamber connecting the heating groove 1316 with the mouthpiece 120. Furthermore, the atomizing seal 160 defines an air inlet that connects the atomizing chamber to the outside environment. This allows airflow from the outside to flow into the atomizing chamber through the air inlet, and the aerosol generated by the atomization of the aerosol-generating substrate 132 can flow into the mouthpiece 120 along with the airflow.

[0047] like Figure 5 and Figure 8 As shown, the aerosol-generating substrate 132 is in the form of a strip or sheet. Specifically, the strip-shaped aerosol-generating substrate 132 can be wound layer by layer along a circumferential direction to form a substrate roll for storage in the main box body 131, or it can be folded back and forth along a straight line to form a substrate stack for storage in the main box body 131. The sheet-shaped aerosol-generating substrate 132 can be stacked layer by layer along a straight line to form a substrate stack for storage in the main box body 131. It will be appreciated that the storage method of the aerosol-generating substrate 132 is not limited, and different winding and folding methods can be used to form different shapes as needed.

[0048] The aerosol-generating matrix 132 preferably has a thickness of 0.1 mm to 0.8 mm and a width of 3 mm to 10 mm. The heating element 174 can sequentially heat various portions of the aerosol-generating matrix 132. Compared to the cylindrical aerosol-generating matrices of the prior art, the sheet- and ribbon-shaped aerosol-generating matrices 132 are much thinner. Therefore, during heating, the temperature rises evenly and rapidly. The aerosol generated by the heated atomization of the aerosol-generating matrix 132 has a short escape path, eliminating the need for preheating. It is understood that the specific thickness and width of the aerosol-generating matrix 132 are not limited and can be adjusted to meet different requirements.

[0049] The aerosol-generating matrix 132 is formed by mixing and slurrying one or more of tobacco leaves, expanded tobacco stems, tobacco particles, tea leaves, and mint leaves with a smoke-generating agent such as propylene glycol, glycerin, or other polyols, as well as flavorings and fragrances. This mixture is then atomized upon heating to produce an aerosol for inhalation. It is understood that the material forming the aerosol-generating matrix 132 is not limited to this and can be customized to meet different requirements.

[0050] In some embodiments, electromagnetic heating units are evenly distributed within the aerosol-generating matrix 132. The electromagnetic heating units can sense the magnetic field generated by the heating element 174 and generate current, thereby causing the charges thereon to move at high speed and irregularly, thereby generating heat energy through collision and friction, thereby heating the aerosol-generating matrix 132. Specifically, the electromagnetic heating units are formed from ferromagnetic materials, such as one or more of iron, cobalt, nickel, and alloys thereof, rare earth elements, and alloys thereof, and can be in the form of one or more of granules, powder, fibers, or flakes.

[0051] In some embodiments, the aerosol-generating substrate 132 includes at least one atomizing layer 1322 and at least one supporting layer 1323. The atomizing layers 1322 and the supporting layers 1323 are alternately stacked along the thickness direction. The supporting layers 1323 are used to support the atomizing layer 1322 and improve the tensile and shear resistance of the aerosol-generating substrate 132. The atomizing layer 1322 between two supporting layers 1323 is defined as one atomizing layer 1322.

[0052] See also Figure 9 Specifically, in one embodiment, the aerosol-generating substrate 132 includes an atomizing layer 1322 and a support layer 1323, with the support layer 1323 located on the upper surface or the lower surface of 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. It will be appreciated that the number of atomizing layers 1322 and support layers 1323 is not limited and can be provided as needed.

[0053] The support layer 1323 can be formed from a metal material, such as one or more of gold, silver, copper, iron, tin, zinc, nickel, aluminum, tungsten, molybdenum, tantalum, niobium, titanium, nickel-based, cobalt-based, steel, stainless steel, and alloy foils thereof, or a heat-resistant non-metallic film tape, such as one or more of fiberglass, 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 can be equal to, or smaller than, the width of the atomized layer 1322. Thus, the support layer 1323 has superior mechanical properties compared to the atomized layer 1322, thereby improving the tensile and shear resistance of the aerosol-generating substrate 132. Furthermore, the support layer 1323 can transfer heat to preheat portions not in contact with the heater element, further improving heating uniformity.

[0054] Furthermore, the support layer 1323 is provided with interconnecting holes 1323a extending through the thickness thereof. Multiple interconnecting holes 1323a are arranged in an array across at least a portion of the support layer 1323. The interconnecting holes 1323a are used to allow aerosol to flow from the current atomizing layer 1322 to an adjacent atomizing layer 1322 or to the outside. To ensure a sufficiently high aerosol overflow rate, the porosity of the support layer 1323 (i.e., the ratio of the total area of ​​the interconnecting holes 1323a per unit area to the unit area) is 30% or greater. Specifically, when the aerosol generating matrix 132 includes an atomizing layer 1322 and a 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 atomization of the atomizing layer 1322 flows out through the interconnecting holes 1323a provided in the support layer 1323. When the aerosol generating matrix 132 includes two atomizing layers 1322 and a support layer 1323 , and the support layer 1323 is located between the two atomizing layers 1322 , the aerosol generated by atomization of one atomizing layer 1322 can flow to the other atomizing layer 1323 through the connecting holes 1323 a provided on the support layer 1323 .

[0055] See also Figure 6 In the first embodiment of the present application, the aerosol-generating substrate cartridge 130 includes a conveying mechanism 133 for releasing the aerosol-generating substrate 132. The conveying mechanism 133 includes a release center wheel 1232 and a conveying assembly 1334. The release center wheel 1232 is rotatably mounted within the storage chamber 1312. The central axis of the release center wheel 1232 extends along a third direction, and one end of the strip of aerosol-generating substrate 132 is wound around the release center wheel 1232. The conveying assembly 1334 is located between the storage chamber 1312 and the recovery chamber 1314, and on the side of the heating tank 1316 proximal to the recovery chamber 1314. The conveying assembly 1334 is configured to apply a pulling force to one end of the aerosol-generating substrate 132, causing different regions of the aerosol-generating substrate 132 to sequentially enter the heating tank 1316. The conveying assembly 1334 also drives the release center wheel 1232 to rotate, thereby synchronously releasing the aerosol-generating substrate 132.

[0056] Specifically, the conveying assembly 1334 includes two spaced-apart conveying wheels 1334a rotatably mounted to the main housing 131, with the central axes of the two conveying wheels 1334a extending along the third direction. A clamping gap is defined between the two conveying wheels 1334a, through which the aerosol-generating substrate 132 passes. The drive assembly 180 is in driving connection with one of the conveying wheels 1334a to rotate. As a result, the aerosol-generating substrate 132 within the clamping gap is continuously moved forward by the rotation of the conveying wheel 1334a, passing through the heating tank 1316 and entering the recovery chamber 1314.

[0057] See also Figure 5In the second embodiment of the present application, the aerosol generating cartridge includes a conveying mechanism 134 for releasing the aerosol-generating substrate 132. The conveying mechanism 134 includes a release center wheel 1341 and a conveying assembly. The conveying assembly includes a recovery center wheel 1343. The release center wheel 1341 is rotatably mounted in the storage chamber 1312, with the central axis of the release center wheel 1341 extending along a third direction. The recovery center wheel 1343 is rotatably mounted in the recovery chamber 1314, with the central axis of the recovery center wheel 1343 extending along the third direction. The leading and trailing ends of the aerosol-generating substrate 132 are respectively wound around the release center wheel 1341 and the recovery center wheel 1343. The drive assembly 180 is in driving connection with the recovery center wheel 1343. Driven by the drive assembly 180, the recovery center wheel 1343 rotates to recover the aerosol-generating substrate 132. The aerosol-generating substrate 132, driven by the recovery center wheel 1343, drives the release center wheel 1341 to rotate synchronously, thereby synchronously releasing the aerosol-generating substrate 132. In some embodiments, the transport assembly further includes a plurality of intermediate pulleys, each of which is located at a different position within the main box body 131 to restrict the movement path of the aerosol-generating substrate 132.

[0058] See also Figure 7 and Figure 8 In the third embodiment of the present application, the aerosol-generating substrate 132 is in the form of a sheet or a strip folded back and forth in one direction. The aerosol-generating substrate cartridge 130 includes a conveying mechanism 135 for releasing the aerosol-generating substrate 132. The conveying mechanism 135 includes a feed roller 1352 and a delivery roller assembly 1354. The feed roller 1352 and the delivery roller assembly 1354 are spaced apart on opposite sides of the heating tank 1316 in the second direction. The feed roller 1352 is located above the storage chamber 1312, and the central axis of the feed roller 1352 extends along the third direction. The delivery roller assembly 1354 includes two delivery rollers 1354a spaced apart in the first direction. The central axes of the delivery rollers 1354a extend along the third direction, forming a delivery gap between the two delivery rollers 1354a. The drive assembly 180 is transmission-connected to the feed roller 1352 and one of the delivery rollers 1354a, thereby driving the feed roller 1352 and the delivery roller 1354a to rotate, respectively.

[0059] In this way, the feed wheel 1352, driven by the driving component 180, applies a forward force to the aerosol generating matrix 132. One end of the aerosol generating matrix 132 is released under the push of the feed wheel 1352 and enters the heating groove 1316, and then enters the conveying gap formed by the conveying wheel component 1354 and moves to the recovery chamber 1314 under the rotation of the conveying wheel 1354a.

[0060] Furthermore, in the third embodiment, the aerosol generating matrix box 130 also includes a lifting mechanism 136, which is used to push the aerosol generating matrix 132 close to the feed rubbing wheel 1352, so that each piece or each section of the aerosol generating matrix 132 contacts the feed rubbing wheel 1352 in turn, and then enters the heating tank 1316 under the push of the feed rubbing wheel 1352.

[0061] Specifically, the lifting mechanism 136 is located within the storage chamber 1312 and includes a lifting base 1361 and a lifting drive 1363. The aerosol generating substrate 132 is used to support the aerosol generating substrate 132. The lifting drive 1363 can drive the lifting base 1361 to move in a first direction, thereby ensuring that the aerosol generating substrate 132 is always in contact with the feed roller 1352. In a preferred embodiment, the lifting drive 1363 is an elastic member extending in the first direction. The lifting drive 1363 can apply a pulling force to the lifting base 1361 toward the feed roller 1352. It is understood that the specific structure of the lifting drive 1363 is not limited. In other embodiments, the lifting drive 1363 can be a drive structure such as a screw.

[0062] In some embodiments, the aerosol-generating matrix cartridge 130 further includes a pulverizing mechanism (not shown), which is disposed within the recovery chamber 1314 and is configured to apply force to the aerosol-generating matrix 132 that has entered the recovery chamber 1314, thereby pulverizing the released aerosol-generating matrix 132. It will be appreciated that the specific configuration of the pulverizing mechanism is not limited, as long as it can pulverize the aerosol-generating matrix 132. In other embodiments, a compression mechanism may be further disposed within the recovery chamber 1314 to compress the recovered aerosol-generating matrix 132, thereby reducing space occupancy and the volume of the recovery chamber 1314, ultimately facilitating miniaturization of the atomization device 100.

[0063] Please refer again Figures 2 to 5 In some embodiments, a mounting post 1141 is protruding from a side of the main housing 110 away from the accommodating chamber 118, communicating with the atomizing chamber. One end of a cylindrical mouthpiece 120 is inserted into the mounting post 1141, while the other end of the mouthpiece 120 extends in a third direction away from the housing top wall 116. This allows aerosol generated by the aerosol generating substrate 132 in the aerosol generating substrate cartridge 130 to flow out through the mouthpiece 120.

[0064] The power supply assembly 150 is located on one side of the accommodating chamber 118 in the second direction, and the heating assembly 170 is located on one side of the power supply assembly 150 in the first direction. The heating assembly 170 includes a heating mounting housing 172 and a heating element 174. The heating mounting housing 172 is coupled to the main box body 131. One end of the heating element 174 is confined within the main box body 131 and electrically connected to the power supply assembly 150. The other end of the heating element 174 extends along the third direction into the heating groove 1316 to heat the aerosol generating substrate 132.

[0065] Specifically, in some embodiments, the heating element 174 is configured as a resistive heater, an electromagnetic induction heater, or a plasma heater. The heating element 174 is attached to the aerosol-generating substrate to conduct heat to the aerosol-generating substrate. Specifically, in some embodiments, the heating element 174 heats the aerosol-generating substrate 132 using conductive heating. The heating element 174 is a flat heating plate, an arc-shaped heating plate, or a heating block that generates heat when powered. The heating element 174 extends into the heating slot 1316 and directly contacts the aerosol-generating substrate 132, thereby heating the aerosol-generating substrate 132 through conductive heating.

[0066] In other embodiments, an electromagnetic heating unit is disposed within the aerosol-generating substrate 132. The heating element 174 is an electromagnetic heating coil. The heating element 174 extends into the heating tank 1316 and is spaced apart from the aerosol-generating substrate 132. When energized, the heating element 174 generates an alternating magnetic field to stimulate the aerosol-generating substrate 132 to generate an alternating current, thereby generating heat and atomization. Preferably, the distance between the heating element 174 and the aerosol-generating substrate 132 is 0.5 mm to 2.0 mm.

[0067] In some other embodiments, the heating assembly 170 is configured as a microwave heating device or an infrared radiation heating device, and the heating assembly 170 is adjacent to the aerosol-generating substrate to transmit microwaves or infrared radiation to the aerosol-generating substrate.

[0068] The driving component 180 is located on one side of the power supply component 150 in the second direction of the accommodating chamber 118. The driving component 180 includes a driving motor, which is transmission-connected to the conveying mechanism (133\134\135) to drive the conveying mechanism (133\134\135) to release and recover the aerosol-generating matrix 132.

[0069] In some embodiments, the atomizing device 100 further includes a feed detection assembly 190 communicatively connected to the control unit. The feed detection assembly 190 is used to obtain the release length of the aerosol-generating substrate 132, thereby controlling the working state of the drive assembly 180, thereby causing the conveying mechanism (133\134\135) to periodically release the aerosol-generating substrate 132. That is, the control unit controls the conveying mechanism (133\134\135) to release the aerosol-generating substrate 132 in a timely and quantitative manner, thereby timely updating the aerosol-generating substrate 132 in the heating tank 1316, while ensuring maximum energy utilization and avoiding overheating of the aerosol-generating substrate 132. Preferably, the release length of each cycle is not less than the length of the heating tank 1316, thereby avoiding repeated heating of the heated portion.

[0070] Specifically, the main body 131 of the aerosol-generating substrate cartridge 130, which is provided with a heating tank 1316, has a detection tank 1318 at one end thereof, connecting the storage chamber 1312 and the heating tank 1316. The aerosol-generating substrate 132 released from the storage chamber 1312 is inspected by the detection tank 1318 and then heated in the heating tank 1316. The feed detection assembly 190 includes a detection shaft 192, a pressure wheel 194, and a detection unit. The detection shaft 192 extends into the detection tank 1318 along a third direction to contact a side surface of the aerosol-generating substrate 132. The detection shaft 192 is driven by the moving aerosol-generating substrate 132 to rotate. The pressure wheel 194 is located on one side of the detection shaft 192 in the first direction and is used to apply pressure to the aerosol-generating substrate 132 to ensure that the aerosol-generating substrate 132 is tightly attached to the detection shaft 192. The feed detection unit is connected to the detection shaft 192 and is located outside the main box body 131. The feed detection unit is used to detect the rotation angle of the shaft 192 to obtain the release length of the aerosol generating matrix 132, and then feedback the control signal to the drive component 180 to control the working state of the drive component 180.

[0071] Furthermore, the detection component also includes a pressure wheel bracket 196, one end of the pressure wheel bracket 196 is connected to the pressure wheel 194, and the other end of the pressure wheel bracket 196 is connected to the outside of the main shell 110. The user can push the pressure wheel bracket 196 in a first direction to adjust the gap between the pressure wheel 194 and the detection shaft 192, thereby facilitating the replacement of the aerosol generating box or the aerosol generating matrix 132.

[0072] It will be appreciated that the detection method of the feed detection assembly 190 is not limited to this. In other embodiments, the feed detection assembly 190 may also control the operating state of the drive assembly 180 by detecting the number of rotations of the drive motor of the drive assembly 180. In other embodiments, detection marks are provided at intervals along the length of the aerosol-generating substrate 132. The detection marks are formed by mechanical structural features, optical features, or magnetic features. The feed detection assembly 190 may detect the number of detection marks to obtain the release length of the aerosol-generating substrate 132. Specifically, in one embodiment, when the aerosol-generating substrate 132 is provided with a support layer 1323, metering holes may be provided on opposite sides of the support layer 1323 in the width direction and spaced along the length thereof. The release length of the aerosol-generating substrate 132 can be obtained by detecting the number of metering holes passing through the feed detection assembly 190.

[0073] In some embodiments, the atomizing device 100 further includes a remaining amount detection unit in communication with the control unit. The remaining amount detection unit is configured to detect the remaining amount of the unreleased portion of the aerosol-generating substrate 132, thereby prompting the user to promptly check and replace the aerosol-generating substrate cartridge 130 or the aerosol-generating substrate 132. Specifically, the remaining amount detection unit can detect changes in the blocking current of the motor of the drive assembly 180 or changes in the temperature curve of the heater 174 to obtain the remaining amount of the aerosol-generating substrate 132 in the storage chamber 1312 and provide feedback to the control unit, thereby generating output including but not limited to display, vibration, and sound to prompt the user to check and replace the aerosol-generating substrate cartridge 130.

[0074] In some embodiments, the atomizing device 100 is further provided with a sensor in communication with the control unit. The sensor is used to obtain the number of puffs and the usage time to inform the user of the usage status of the atomizing device 100.

[0075] In some embodiments, the main housing 110 is provided with an installation detection unit, and the aerosol-generating matrix cartridge 130 is provided with a sensing element that matches the installation detection unit. The installation detection unit can detect the sensing element to determine whether the aerosol-generating matrix cartridge 130 is present in the accommodating cavity 118. Specifically, the installation detection unit includes, but is not limited to, a Hall effect sensor and a photoelectric sensor, and the sensing element includes, but is not limited to, a magnetic element that matches the Hall effect sensor or a light shield that matches the photoelectric sensor. The Hall effect sensor can determine whether the aerosol-generating matrix cartridge 130 is present in the accommodating cavity 118 by detecting the presence of the magnetic element, and the photoelectric sensor can determine whether the aerosol-generating matrix cartridge 130 is present in the accommodating cavity 118 by detecting the presence of the light shield.

[0076] In the above-mentioned atomizing device 100, different areas of the strip-shaped or sheet-shaped aerosol generating substrate 132 are heated in sequence by the heating element 174. Since the thickness of the aerosol generating substrate 132 heated each time is very thin, the heating speed is fast, the aerosol overflow time is short, and different areas of the aerosol generating substrate 132 can be heated evenly, thereby having a higher energy utilization rate and a higher taste consistency.

[0077] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
