Technical Field

[0001] This application relates to the field of tobacco product technology, and more specifically, to an aerosol generating product and an aerosol generating apparatus. Background Technology

[0002] An aerosol generating device is a device that uses control circuits and heating elements to heat an aerosol-generating product, thereby atomizing the aerosol medium within it. A common aerosol-generating product is a cigarette. When heating a cigarette, the temperature needs to be controlled within the range of 240 to 350°C to release the nicotine aerosol in the cigarette and achieve a smoking experience close to that of a traditional cigarette. However, the applicant found in experiments that when using most aerosol generating devices to heat cigarettes, the aerosol-generated product is difficult to remove after heating.

[0003] In summary, improving the ease of unloading products generated from heated aerosols is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide an aerosol generating product and an aerosol generating device, wherein the aerosol generating product is highly convenient to load and unload.

[0005] To achieve the above objectives, this application provides the following technical solution: An aerosol generating device includes: a housing, a mouthpiece assembly, and a heating assembly; The housing has a receiving channel, and the mouthpiece assembly can be inserted into or removed from the receiving channel; The heating assembly includes a heating element, which is disposed inside the outer shell and located at the inner end of the accommodating channel. The heating element is used to insert into the aerosol-generated product. The mouthpiece assembly includes a mouthpiece unit, a drive assembly, and several fixing members.

The connecting ends of the fixing members are rotatably connected to the loading end of the mouthpiece unit. The several fixing members are arranged circumferentially along the mouthpiece unit. The fixing members can rotate to a blocking position or a clearance position. When the fixing member is in the blocking position, its free end faces the loading port to block the aerosol-generating product. When the fixing member is in the clearance position, its free end is away from the loading port to avoid the aerosol-generating product.

[0007] Preferably, the mouthpiece unit includes a mouthpiece body, the release drive has a connecting ring, the connecting ring is slidably sleeved on the outer periphery of the mouthpiece body, and the inner periphery of the connecting ring has a positioning opening; The outer side of the mouthpiece body has a pair of positioning protrusions along its circumference. Two of the pair of positioning protrusions are arranged along the length of the mouthpiece body. Of the pair of positioning protrusions, positioning protrusion A is close to the suction end of the mouthpiece body, and positioning protrusion B is close to the loading end of the mouthpiece body. When the release drive is in the first position, positioning protrusion B is engaged in the positioning opening. When the release drive is in the second position, positioning protrusion A is engaged in the positioning opening.

[0008] Preferably, the peripheral wall of the loading end of the mouthpiece body has a plurality of mounting holes, and the plurality of mounting holes are arranged along the circumference of the mouthpiece unit; The mouthpiece unit also includes a positioning ring, which is sleeved inside the loading end of the mouthpiece body. The positioning ring has several rotating shaft segments along its circumference, and several fixing members are movably disposed in the corresponding mounting openings and rotatably connected to the corresponding rotating shaft segments.

[0009] Preferably, the outer periphery of the mouthpiece body has a movable annular groove and a plurality of movable linear grooves. The movable annular groove extends circumferentially along the mouthpiece body, and the plurality of movable linear grooves are arranged circumferentially along the mouthpiece body. The connecting ring is slidably fitted in the movable annular groove, and the plurality of driving feet are slidably inserted into the corresponding movable linear grooves.

[0010] Preferably, the mouthpiece unit further includes an elastic sleeve, which can be telescopically fitted inside the mouthpiece body along the length direction of the mouthpiece body.

[0011] Preferably, the outer periphery of the mouthpiece body also has a locking opening; It also includes a locking component, which is disposed inside the housing and located on the side of the receiving channel; the locking component includes a power component and a locking member, the output end of the power component is connected to the locking member, and is used to drive the locking member to move to a locked position or an unlocked position; when the locking member is in the locked position, the locking member is inserted into the locking port; when the locking member is in the unlocked position, the locking member is disengaged from the locking port.

[0012] Preferably, the cross-sectional shape of the loading port is monolithic, the heating element is sheet-like, and the heating element extends along the long axis of the cross-section of the loading port.

[0013] Preferably, the device further includes a battery assembly disposed inside the housing and electrically connected to the heating assembly and the power assembly, for providing the electrical energy required for the operation of the heating assembly and the power assembly.

[0014] An aerosol generating product, used in any of the aerosol generating apparatuses described above; The aerosol-generated product has a columnar structure, and the cross-sectional shape of the aerosol-generated product is monolithic. The aerosol-generated product has a heating hole at its center for inserting a heating component.

[0015] In this application, the outer shell is a hollow shell with an insertion port at one end. The insertion port communicates with the inner cavity of the outer shell to form a vertical receiving channel for inserting the mouthpiece assembly. The mouthpiece unit is a tubular structure with a variable diameter channel at its center. The internal section of the loading end of the mouthpiece unit is the loading port for inserting the aerosol generating product. In addition to the loading port, the remaining cavity in the variable diameter channel of the mouthpiece unit is the atomization channel. In other words, the mouthpiece unit also has an atomization channel extending along its own length. The atomization channel is connected to the loading port. During the heating process, the aerosol generated by the aerosol generating product will be discharged upward through the atomization channel. Correspondingly, a fixing member is mounted on the mouthpiece unit. The connecting end of the fixing member is rotatably set at the loading end of the mouthpiece unit, and the rotation center line of the fixing member is perpendicular to the length direction of the mouthpiece unit. In other words, the fixing member is rotatably set on the mouthpiece unit about the width direction of the mouthpiece unit. The free end of the fixing member is deflected to the outside of the mouthpiece unit to a clearance position, that is, the loading port is opened, so that the aerosol generating product can be smoothly inserted into the loading port. Conversely, the free end of the fixing member is deflected to the inside of the mouthpiece unit to a blocking position, that is, the loading port is closed, so that it can abut against the outer end of the aerosol generating product, thereby blocking and positioning the aerosol generating product loaded on the mouthpiece unit. Furthermore, at least two fixing members are arranged sequentially along the circumference of the mouthpiece unit. The several fixing members cooperate with each other to block and position the aerosol generating product loaded on the mouthpiece unit, preventing it from falling off accidentally, or to make way for the loading or unloading of the aerosol generating product, that is, to facilitate the removal and replacement of the aerosol generating product. In conjunction with this, a drive assembly is also mounted on the mouthpiece unit. The drive assembly is movably mounted on the mouthpiece unit by means of sliding and / or rotation, and is connected to the fixing member. It can push or pull the fixing member to drive the fixing member to rotate to the blocking position or the avoidance position.

[0016] In addition, a heating component is installed inside the outer casing. The heating component is located at the end of the receiving channel, and the heating element in the heating component is inserted into the receiving channel. After the mouthpiece unit is inserted into the receiving channel, the heating element is simultaneously inserted into the loading port. When an aerosol generating product is placed in the loading port, the heating element is simultaneously inserted into the aerosol generating product. The width and length of the heating element match the width and depth of the loading port, and the width and length of the matching aerosol generating product also match the width and depth of the loading port. This allows the heating element to be inserted into the interior of the aerosol generating product and effectively ensures the contact area between the heating element and the aerosol generating product.

[0017] The mouthpiece assembly is used in combination with the aerosol generating product. In specific use, first remove the mouthpiece assembly, place the aerosol generating product into the loading port to complete the loading of the aerosol generating product, and then insert the mouthpiece assembly into the receiving channel so that the heating element extends into the interior of the aerosol generating product. Then, start the heating component to heat the aerosol generating product.

[0018] The beneficial effects are as follows: During the central heating of the aerosol-generating product using a heating element, even if the size of the aerosol-generating product shrinks significantly due to the evaporation of components such as moisture and / or glycerin, and the decomposition of constituent substances, the heat is directly and rapidly conducted within the aerosol-generating product, ensuring heating uniformity and efficiency. Furthermore, because the mouthpiece assembly is equipped with a drive component and a fixing component, it has the function of fixing the aerosol-generating product. Even if the aerosol-generating product adheres to the heating element, when the mouthpiece assembly is removed, the aerosol-generating product it carries is easily detached from the heating element due to the fixing component. In other words, the aerosol-generating product is pulled out together with the mouthpiece assembly, avoiding the risk of it falling into the receiving channel due to volume shrinkage. It can also be easily detached from the mouthpiece unit, meaning that the aerosol-generating product is highly convenient to unload from the aerosol-generating device. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] The core of this application is to provide an aerosol generating product and an aerosol generating device, wherein the aerosol generating product 7 is highly convenient to load and unload.

[0024] This application provides an aerosol generating device, including a housing 1, a mouthpiece assembly 2, and a heating assembly 3; wherein, the housing 1 has a receiving channel 11, and the mouthpiece assembly 2 can be inserted into or removed from the receiving channel 11; the heating assembly 3 includes a heating element 301, which is disposed inside the housing 1 and located at the inner end of the receiving channel 11, and is used to insert an aerosol generating product 7; the mouthpiece assembly 2 includes a mouthpiece unit 21, a driving assembly 22, and several fixing members 23; the loading end of the mouthpiece unit 21 has a loading port 2101 for inserting the aerosol generating product 7. Product 7; The connecting end of the fixing member 23 is rotatably connected to the loading end of the mouthpiece unit 21. Several fixing members 23 are arranged circumferentially along the mouthpiece unit 21. The fixing members 23 can rotate to the blocking position or the avoidance position. When the fixing member 23 is in the blocking position, its free end is facing the loading port 2101 so as to block the aerosol generating product 7. When the fixing member 23 is in the avoidance position, its free end is away from the loading port 2101 so as to avoid the aerosol generating product 7. The driving component 22 is movably disposed on the mouthpiece unit 21 and is used to push several fixing members 23 to rotate synchronously towards or away from each other.

[0025] Please refer to Figures 1 to 3 The outer shell 1 is a hollow shell with an insertion port at its top. The insertion port connects to the inner cavity of the outer shell 1 to form a vertical receiving channel 11 for inserting the mouthpiece assembly 2. In the attached figure, the lower end of the mouthpiece unit 21 is the loading end, and the upper end is the suction end. Please refer to Figures 1 to 3 , Figure 11 , Figure 16 Furthermore, the mouthpiece unit 21 is a tubular structure with a variable diameter channel at its center. The internal section at the lower end of the mouthpiece unit 21 is a loading port 2101 for inserting the aerosol generating product 7. In addition to the loading port 2101, the remaining cavity section in the variable diameter channel of the mouthpiece unit 21 is an atomization channel 2102. In other words, the mouthpiece unit 21 also has an atomization channel 2102 extending along its own length direction. The atomization channel 2102 is connected to the loading port 2101. During the heating process, the aerosol generated by the aerosol generating product 7 will be discharged upward through the atomization channel 2102. Please refer to Figures 6 to 16 Correspondingly, a fixing member 23 is mounted on the mouthpiece unit 21, with its upper connecting end rotatably disposed at the lower end of the mouthpiece unit 21; optionally, the rotation center line of the fixing member 23 is perpendicular to the length direction of the mouthpiece unit 21, in other words, the fixing member 23 is rotatably disposed on the mouthpiece unit 21 about the width direction of the mouthpiece unit 21; the lower free end of the fixing member 23 is deflected towards the outside of the mouthpiece unit 21. Figure 7 and Figure 9The indicated clearance position, i.e., opening the loading port 2101, allows the aerosol-generated product 7 to be smoothly inserted into the loading port 2101; conversely, the lower free end of the fixing member 23 is deflected towards the inside of the mouthpiece unit 21. Figure 12 and Figure 14 The blocking position shown, i.e., closing the loading port 2101, can abut against the lower end of the aerosol generating product 7, thereby blocking and positioning the aerosol generating product 7 loaded on the mouthpiece unit 21; and, at least two fixing members 23 are arranged sequentially along the circumference of the mouthpiece unit 21, so that several fixing members 23 cooperate with each other to block and position the aerosol generating product 7 loaded on the mouthpiece unit 21, preventing it from falling off accidentally, or to make way for easy loading or unloading of the aerosol generating product 7, that is, to facilitate the removal and replacement of the aerosol generating product 7. Please refer to Figures 6 to 16 Correspondingly, a drive assembly 22 is also mounted on the mouthpiece unit 21. The drive assembly 22 is movably mounted on the mouthpiece unit 21 by means of sliding and / or rotation, and the drive assembly 22 is connected to the fixing member 23. It can push or pull the fixing member 23 to drive the fixing member 23 to rotate to the blocking position or the avoidance position. Of course, the drive assembly 22 is not limited to the above embodiment that can both pull and push the fixing member 23. It is preferred to adopt an embodiment that includes a release drive member 221 and a plurality of reset drive members 222.

[0026] In addition, a heating component 3 is installed inside the outer casing 1. The heating component 3 is located at the lower end (end, or bottom) of the receiving channel 11, and the heating element 301 in the heating component 3 is inserted into the receiving channel 11. The heating element 301 can be a cylindrical structure or a sheet structure, etc. After the mouthpiece unit 21 is inserted into the receiving channel 11, the heating element 301 will be inserted into the loading port 2101 at the same time. When the aerosol generating product 7 is placed in the loading port 2101, the heating element 301 will be inserted into the aerosol generating product 7 at the same time. The width and length of the heating element 301 match the width and depth of the loading port 2101. The width and length of the aerosol generating product 7 also match the width and depth of the loading port 2101, so that the heating element 301 can be inserted into the interior of the aerosol generating product 7 and effectively ensure the contact area between the heating element 301 and the aerosol generating product 7.

[0027] The mouthpiece assembly 2 is used in combination with the aerosol generating product 7. In specific use, first remove the mouthpiece assembly 2, place the aerosol generating product 7 into the loading port 2101 to complete the loading of the aerosol generating product 7, and then insert the mouthpiece assembly 2 into the receiving channel 11 so that the heating element 301 extends into the interior of the aerosol generating product 7, and start the heating component 3 to heat the aerosol generating product 7.

[0028] The beneficial effects are as follows: during the process of centrally heating the aerosol generating product 7 using the heating element 301, even if the size of the aerosol generating product 7 shrinks significantly due to the evaporation of components such as moisture and / or glycerin and the decomposition of constituent substances, the heat will be directly and rapidly conducted in the aerosol generating product 7 during the heating process, ensuring the heating uniformity and heating efficiency of the aerosol generating product 7; and since the mouthpiece assembly 2 is equipped with the driving component 22 and the fixing component 23, it has the function of fixing the aerosol generating product 7. Therefore, even if the aerosol generating product 7 adheres to the heating element 301, when the mouthpiece assembly 2 is removed, the aerosol generating product 7 loaded on it can be easily detached from the heating element 301 due to the fixing component 23. That is, the aerosol generating product 7 will be pulled out together with the mouthpiece assembly 2, avoiding the risk of the aerosol generating product 7 falling into the receiving channel 11 due to the volume shrinkage of the aerosol generating product 7, and can be easily detached from the mouthpiece unit 21. In other words, the aerosol generating product 7 is highly convenient to unload from the aerosol generating device.

[0029] Based on the above embodiments, the drive assembly 22 includes a release drive member 221 and a plurality of reset drive members 222; the release drive member 221 is sleeved on the outer periphery of the mouthpiece unit 21 and can slide along the length direction of the mouthpiece unit 21; the release drive member 221 has a plurality of drive feet 2211 on the side near the loading end of the mouthpiece unit 21; the outer side of the fixing member 23 has a groove 231, and the plurality of drive feet 2211 can be slidably inserted into or withdrawn from the groove 231 of the corresponding fixing member 23; when the release drive member 221 is in the first position, the drive feet 2211 are located at the end of the groove 231, so that the fixing member 23 is in the blocking position; when the release drive member 221 is in the second position, the drive feet 2211 are disengaged from the fixing member 23; the plurality of reset drive members 222 are used to drive the corresponding fixing member 23 to rotate to the avoidance position.

[0030] Please refer to Figures 6 to 16 , Figure 18 , Figure 20 The release drive 221 can achieve linear movement vertically on the mouthpiece unit 21. The lower end of the release drive 221 has several drive feet 2211, which can be plates or cylinders, etc. The several drive feet 2211 are arranged sequentially along the circumference of the mouthpiece unit 21. Correspondingly, the fixing member 23 is rotatably disposed on the outside of the mouthpiece unit 21. Specifically, the upper inner side of the fixing member 23 has a connecting part with a C-shaped groove, and the rotating shaft provided in the mouthpiece unit 21 passes through the C-shaped groove. The upper outer side of the fixing member 23 has a linear sliding groove 231 extending vertically, and the several fixing members 23 are also arranged sequentially along the circumference of the mouthpiece unit 21. The several drive feet 2211 and the several fixing members 23 correspond one-to-one along the length direction of the mouthpiece unit 21.

[0031] During the downward movement of the release drive 221, several drive feet 2211 will first insert into the top opening of the corresponding slide groove 231, and then continue to move downward along the slide groove 231 to push the fixing member 23 to rotate, so that the free end of the fixing member 23 deflects towards the inside of the mouthpiece unit 21. The drive feet 2211 slide along the slide groove 231 until they abut against the bottom end wall of the slide groove 231, that is, they move to the first position mentioned above. Figures 12 to 16 As shown, this causes the fixing member 23 to rotate to Figure 12 and Figure 14 The indicated blocking position closes the loading port 2101; conversely, during the upward movement of the release drive 221, several drive feet 2211 will first move upward along the corresponding slide groove 231, and then exit from the top opening of the slide groove 231, i.e., move to the aforementioned second position, as shown. Figures 7 to 11 As shown, release fastener 23.

[0032] Correspondingly, a reset drive 222 is provided at the lower end of the mouthpiece unit 21 to apply a preload force to the fixing member 23, causing it to deflect outwards from the mouthpiece unit 21. After the fixing member 23 is released, under the drive of the reset drive 222, the free end of the fixing member 23 will deflect outwards from the mouthpiece unit 21. Figure 7 and Figure 9 The indicated clearance position is used to open the loading port 2101. The release drive 221 and reset drive 222 then cooperate to facilitate the replacement of the aerosol-generated product 7.

[0033] It should be noted that the type of reset drive component 222 is not limited, as long as it can achieve the intended function of resetting the drive fixing component 23 to the avoidance position. Any type is acceptable. Figure 6 The torsion spring shown is sleeved on the pivot section 2121 of the positioning ring 212, and the two ends of the torsion spring abut against the fixing member 23 and the mouthpiece body 211, or a metal sheet with elastic potential energy, etc.

[0034] Based on the above embodiments, the mouthpiece unit 21 includes a mouthpiece body 211, and a release drive member 221 has a connecting ring 2212. The connecting ring 2212 is slidably sleeved on the outer periphery of the mouthpiece body 211, and the inner periphery of the connecting ring 2212 has a positioning opening 22121. The outer side of the mouthpiece body 211 has a pair of positioning protrusions along its own circumference. Two of the pair of positioning protrusions are arranged along the length direction of the mouthpiece body 211. Among the pair of positioning protrusions, positioning protrusion A2112 is close to the suction end of the mouthpiece body 211, and positioning protrusion B2113 is close to the loading end of the mouthpiece body 211. When the release drive member 221 is in the first position, positioning protrusion B2113 is engaged in the positioning opening 22121. When the release drive member 221 is in the second position, positioning protrusion A2112 is engaged in the positioning opening 22121.

[0035] Please refer to Figures 6 to 17 The outer periphery of the mouthpiece body 211 is machined with a pair of positioning protrusions that cooperate with the release drive component 221. The positioning protrusions can adopt a dome structure or a strip protrusion with a triangular cross section, etc.; a pair of positioning protrusions consists of two positioning protrusions, namely positioning protrusion A2112 and positioning protrusion B2113. Positioning protrusion A2112 and positioning protrusion B2113 are located at different height positions of the mouthpiece unit 21, and positioning protrusion A2112 is located above positioning protrusion B2113.

[0036] In conjunction with this, please refer to Figure 6 and Figure 18 The release drive member 221 has a connecting ring 2212, which can be slidably sleeved on the outside of the tube segment of the mouthpiece unit 21 with the above-mentioned paired positioning protrusions. The connecting ring 2212 can connect several drive feet 2211 into one unit to achieve linkage. Furthermore, the inner circumference of the connecting ring 2212 is machined to form a positioning port 22121. During the sliding process of the release drive member 221 along the mouthpiece body 211, it can selectively engage with the positioning protrusion A2112 or the positioning protrusion B2113.

[0037] When the aerosol generating product 7 needs to be loaded, before the aerosol generating product 7 is inserted, the positioning port 22121 of the release drive 221 engages with the upper positioning protrusion A2112 to achieve fixation. At this time, the release drive 221 has no limit to the position of the fixing member 23. At the same time, driven by the reset drive 222, the release drive 221 will move towards the outside of the mouthpiece unit 21 to the avoidance position, that is, open the loading port 2101, and then the aerosol generating product 7 can be placed into the loading port 2101. After the aerosol generating product 7 is inserted into the loading port 2101, the release drive 221 slides down, so that the positioning port 22121 of the release drive 221 engages with the lower positioning protrusion B2113. At this time, the drive foot 2211 of the release drive 221 cooperates with the sliding groove 231 of the fixing member 23 to prevent it from flipping outward under the action of the reset drive 222. The bottom end of the fixing member 23 cooperates with the bottom end of the aerosol generating product 7.

[0038] When it is necessary to unload the aerosol-generating product 7, that is, after heating is completed, the mouthpiece assembly 2 is pulled out. In order to remove the aerosol-generating product 7, the release drive 221 is pushed upward until the positioning port 22121 is engaged with the positioning protrusion A2112 above. At this time, the drive foot 2211 of the release drive 221 is disengaged from the sliding groove 231 of the fixing member 23. Under the action of the reset drive 222, the fixing member 23 is reset outward, thereby canceling the fixation on the bottom of the aerosol-generating product 7, and then the aerosol-generating product 7 can be smoothly removed from the mouthpiece assembly 2.

[0040] Based on the above embodiments, the peripheral wall of the loading end of the mouthpiece body 211 has a plurality of mounting ports 2111, which are arranged along the circumference of the mouthpiece unit 21; the mouthpiece unit 21 also includes a positioning ring 212, which is sleeved inside the loading end of the mouthpiece body 211. The positioning ring 212 has a plurality of rotating shaft segments 2121 along its own circumference, and a plurality of fixing members 23 are movably disposed in the corresponding mounting ports 2111 and rotatably connected to the corresponding rotating shaft segments 2121.

During the vertical sliding process, the plurality of driving feet 2211 can engage with or disengage from the sliding grooves 231 of a plurality of fixing members 23 rotatably disposed in the corresponding mounting openings 2111.

[0042] In conjunction with this, please refer to Figure 6 , Figure 19 To accommodate several rotatable fixing parts 23, the mouthpiece unit 21 is equipped with a positioning ring 212. The fixing parts 23 cooperate with the positioning ring 212 to achieve rotation. The positioning ring 212 is a closed-loop structure formed by alternating connecting shaft sections 2121 and connecting sections. The positioning ring 212 is sleeved on the inner side of the pipe section of the mouthpiece body 211 with the installation port 2111. Furthermore, several shaft sections 2121 are directly opposite the corresponding installation ports 2111. Thus, the fixing parts 23 are movably disposed in the installation ports 2111, while the connecting parts on the inner side of the fixing parts 23 are movably sleeved on the outer side of the corresponding shaft sections 2121. Preferably, when the fixing parts 23 are in the blocking position, the connecting end of the fixing parts 23 is embedded in the installation port 2111, that is, the outer side of the connecting end of the fixing parts 23 does not protrude to the outer side of the mouthpiece body 211. Figure 12 and Figure 14 As shown.

[0043] Based on the above embodiment, the outer periphery of the mouthpiece body 211 has a movable annular groove 2114 and a plurality of movable wire grooves 2115. The movable annular groove 2114 extends circumferentially along the mouthpiece body 211, and the plurality of movable wire grooves 2115 are arranged circumferentially along the mouthpiece body 211.

[0044] Please refer to Figures 6 to 17 A movable annular groove 2114 extending circumferentially is provided on the outer side of the mouthpiece body 211. The dimension of the movable annular groove 2114 along the length of the mouthpiece body 211 is larger than the length of the connecting ring 2212 of the release drive member 221, so the connecting ring 2212 fitted in the movable annular groove 2114 can move along the length of the mouthpiece body 211. Correspondingly, a movable groove 2115 is also provided on the outer side of the mouthpiece body 211. The number of movable grooves 2115 is equal to the number of drive feet 2211, and the number of drive feet 2211 and the number of movable grooves 2115 extend along the length of the mouthpiece body 211. The circumferential directions of the body 211 are one-to-one, and the upper end of the movable groove 2115 is connected to the movable ring groove 2114. Several driving feet 2211 of the release drive member 221 are slidably inserted into the corresponding movable groove 2115. The number of movable grooves 2115 is equal to the number of fixing members 23. Several fixing members and several movable grooves 2115 are one-to-one along the circumferential direction of the mouthpiece body 211. The lower end of the movable groove 2115 is connected to the mounting port 2111. The lower end of the driving foot 2211 of the release drive member 221 can be slidably inserted into the sliding groove 231 of the corresponding fixing member 23.

[0045] Preferably, the connecting ring 2212 of the release drive 221 is embedded in the movable ring groove 2114, that is, the outer side of the connecting ring 2212 of the release drive 221 does not protrude to the outside of the mouthpiece body 211; and the drive foot 2211 of the release drive 221 is embedded in the movable groove 2115, that is, the outer side of the drive foot 2211 of the release drive 221 does not protrude to the outside of the mouthpiece body 211; Figure 12 and Figure 14 As shown, this facilitates the smooth insertion of the mouthpiece assembly 2 into the receiving channel 11 after the aerosol-generated product 7 is loaded.

[0046] Based on the above embodiments, the mouthpiece unit 21 further includes an elastic sleeve 213, which can be stretched and flexibly fitted inside the mouthpiece body 211 along the length direction of the mouthpiece body 211.

[0047] Please refer to Figure 2 , Figure 3 , Figure 6 , Figure 11 , Figure 16The elastic sleeve 213 is a contoured structure of the mouthpiece body 211. The internal cavity of the elastic sleeve 213 is a variable-diameter cavity. The elastic sleeve 213 has a connecting section, a transition connecting section, and a positioning section connected sequentially along its length. The connecting section is inserted between the inner tube and the outer tube at the suction end of the mouthpiece body 211. The transition connecting section and the positioning section are sleeved at the middle position of the length inserted into the mouthpiece body 211. The positioning ring 212 is inserted inside the loading end of the mouthpiece body 211. Furthermore, the internal cavity section of the positioning section... The width of the transition connecting section is greater than the width of the internal cavity of the transition connecting section. The step surface between the transition connecting section and the positioning section and the inner circumferential surface of the positioning section are fitted together with the inner circumferential surface of the positioning ring 212 to form a loading port 2101. After the aerosol generating product 7 is inserted into the loading port 2101, the upper end of the aerosol generating product 7 abuts against the step surface between the transition connecting section and the positioning section of the elastic sleeve 213. The elastic sleeve 213 can work together with the fixing member 23 to fix the aerosol generating product 7 during the heating process.

[0048] At this point, please refer to Figure 2 , Figure 3 The internal channels of the suction end inner tube of the mouthpiece body 211 and the internal channels of the transition connecting section are interconnected to form the aforementioned atomization channel 2102.

[0050] During and after the heating process of aerosol-generated product 7, the surface temperature of aerosol-generated product 7 and the mouthpiece assembly 2 remains high because the heat has not been completely dissipated. To prevent potential burns from direct removal by the user, the aerosol generating device is also equipped with a locking component 4. Please refer to [reference needed]. Figure 4 , Figure 5 , Figure 6 , Figure 17 The locking member reciprocates via an electrically driven power component. The power component drives the locking member to move closer to or further away from the receiving channel 11, inserting or withdrawing it from the locking port 2116. The reciprocating motion of the locking member can be... Figure 4 The linear movement shown is perpendicular to the insertion direction of the mouthpiece assembly 2, or... Figure 5 As shown, the free end of the locking member can engage with the circular, rectangular or other arbitrary-shaped locking opening 2116 on the outside of the mouthpiece body 211 to lock the mouthpiece assembly 2.

[0051] Optionally, the locking component 4 is used to lock the mouthpiece component 2 based on time utilization, such as locking the mouthpiece component 2 during the heating process and for a period of time after heating is completed; alternatively, the locking component 4 is used to lock the mouthpiece component 2 based on the temperature inside the loading port 2101, for example, it also includes a temperature sensor, and the temperature sensor extends into the loading port 2101 to monitor the temperature inside the loading port 2101, and locks the mouthpiece component 2 when the temperature value does not exceed the preset temperature upper limit; of course, the above-mentioned locking logic based on time and temperature can be used alone or in combination.

[0052] It should be noted that there are no restrictions on the type of power component, as long as it can meet the driving requirements of the locking mechanism. For example, the power component can be a combination of a lead screw and a motor, an AC drive based on an electromagnet, or a combination of a worm gear and a motor.

[0053] Furthermore, the housing 1 is also provided with a movable locking switch for controlling the action of the locking component 4 to lock and unlock the mouthpiece component 2.

The heat transmitted by the heating element 301 can be distributed quickly and evenly, and the contact area between the heating element 301 and the aerosol generating product 7 can be effectively increased, which can reduce the preheating time and quickly produce mist. At the same time, it can also ensure that the aerosol generating product 7 is thoroughly heated and produce more smoke.

Further, the heat-conducting sheet 31 has a positioning groove 311 with a semi-circular or rectangular cross-sectional shape, etc. (See reference). Figure 23 , Figure 24 Two pins are embedded in the corresponding positioning grooves 311. After the heat-conducting sheet 31 is assembled with the resistance heating element 32, the pins are limited and fixed by the positioning grooves 311, so that the pins serve as reinforcements for the strength of the heat-conducting sheet 31, thereby further enhancing the torsional strength of the heating element 301.

[0062] It should be noted that the type of resistor 321 is not limited, as long as it can generate heat after being powered on, for example...
