In some embodiments, the fixing tube 123 is disposed in the cover 11, and in particular, the fixing tube 123 is disposed in the sleeve 121 with one end mounted between the sleeve 121 and the end cap 122. The fixing tube 123 accommodates and fixes the aerosol-forming substrate 200.

As shown in fig. 9, in some embodiments, the securing tube 123 is partially disposed within the sleeve 121 and attached at one end to the top wall of the sleeve 121 that mates with the end cap 122. In some embodiments, the stationary tube 123 includes a cylindrical tubular body 123a and an outer flange 123b disposed on the tubular body 123a and having a radial dimension greater than the radial dimension of the tubular body 123 a. The tubular body 123a has a hollow inside and is used for accommodating the aerosol-forming substrate 200. The outer flange 123b may pass through the top wall of the sleeve 121 and is mounted on the top wall of the sleeve 121, so as to connect the fixing tube 123 with the sleeve 121. An opening 1231 is provided at one end of the fixed tube 123, and a receiving cavity 1230 for receiving the aerosol-forming substrate 200 is formed inside. The receiving cavity 1230 may be generally cylindrical and may have a radial dimension slightly greater than the radial dimension of the aerosol-forming substrate 200. The opening 1231 is formed inside the outer flange 123b, communicates with the accommodating chamber 1230, and is provided in correspondence with the insertion/extraction opening 113 for inserting or extracting the aerosol-forming substrate 200 into/from the accommodating chamber 1230. In some embodiments, an end of the fixing tube 123 opposite to the opening 1231 is provided with a supporting wall 1232, and the supporting wall 1232 is used to support the aerosol-forming substrate 200. In some embodiments, the support wall 1232 is provided with a through hole 1233, and the through hole 1233 is used for the heating body 30 to penetrate into the accommodating cavity 1230. In some embodiments, the opening 1231 is provided with a plurality of notches 1234, and the plurality of notches 1234 may be formed in the outer flange 123b along the circumference of the outer flange 123b. The notch 1234 may be used for mounting the fastener 124.

As shown in fig. 10, in some embodiments, the containment assembly 12 further includes a securing member 124, the securing member 124 being configured to secure the aerosol-forming substrate 200. In some embodiments, the securing member 124 may be a resilient securing member, such as a silicone member or a rubber member. Of course, it will be appreciated that in other embodiments, the securing member 124 is not limited to being a resilient securing member, and in other embodiments, the securing member 124 may be omitted. The fixing member 124 is disposed at an opening 1231 of the fixing tube 123, and is used for fixedly connecting the aerosol-forming substrate 200 with the fixing tube 123, so that the aerosol-forming substrate 200 can be driven by an external force to simultaneously drive the whole extractor 10 to slide on the body 21. In some embodiments, the mount 124 includes an annular body 1241 and a resilient protrusion 1242. The ring 1241 is sleeved on the periphery of the notch 1234 at the opening 1231 of the fixing tube 123, and the elastic protrusion 1242 penetrates through the notch 1234 to be arranged in the accommodating cavity 1230 in a protruding manner for tightly abutting against the aerosol-forming substrate 200. The elastic protrusions 1242 may be plural, and the plural elastic protrusions 1242 may be disposed at intervals along the circumference of the opening 1231 and are disposed in one-to-one correspondence with the notches 1234. Of course, it is understood that in other embodiments, the resilient protrusions 1242 are not limited to a plurality, and in other embodiments, the resilient protrusions 1242 may be one.

As further shown in fig. 2,3 and 8, in some embodiments, the dust cap assembly 13 includes a dust cap 131 and an elastic mechanism 132, and the dust cap 131 is slidably disposed on the cover 11. Specifically, the dust cap 131 is slidably mounted on the end wall 112 of the cap 11, and guided by the guide groove 114, and can be slidably engaged with the insertion/extraction opening 113, and can be tightly abutted against the aerosol-forming substrate 200 inserted into the accommodating cavity 1230, so as to fix the aerosol-forming substrate 200 to the extractor 10. In some embodiments, the elastic mechanism 132 is disposed in the cover 11, specifically, between the end cap 122 and the end wall 112, and is connected to the dust cap 131, so as to apply an elastic force to the dust cap 131, so that the dust cap 131 can be driven to slide and cover the insertion opening 113 when the aerosol-forming substrate 200 is extracted from the extractor 10, and the dust cap 131 can be elastically abutted with the aerosol-forming substrate 200 when the aerosol-forming substrate 200 is inserted into the extractor 10, so as to fix the aerosol-forming substrate 200, and facilitate the aerosol-forming substrate 200 to slide on the body 21 under the external force while driving the whole extractor 10.

In some embodiments, the elastic mechanism 132 includes a slider 1321, an elastic member 1322, and a connecting member 1323. The slider 1321 is slidably disposed between the end wall 112 and the end cap 122 and is coupled to the dust cap 131 by a connector 1323. One end of the elastic member 1322 is connected to the slider 1321, and the other end abuts against a side wall of the end cover 122. In some embodiments, the elastic member 1322 may be a spring.

In some embodiments, the dust cap 131 abuts against the aerosol-forming substrate 200 under the urging force of the resilient mechanism 132, and/or the resilient protrusions 1242 of the mount 124 are interference fit with the aerosol-forming substrate 200 and abut against the aerosol-forming substrate 200, such that the aerosol-forming substrate 200 may slide with the extractor 10 as a unit on the body 21. In some embodiments, the dust cap 131 may also have a child lock function, i.e., when inserting the aerosol-forming substrate 200, one hand is required to pull the dust cap 131 and the other hand is required to insert and remove the aerosol-forming substrate 200, which is relatively difficult for a child to prevent the child from operating the device by mistake.

Further, in some embodiments, the body 21 includes a housing 211, and a frame 212. The housing 211 has a cylindrical structure, and one end is provided with a mounting opening 2111 for mounting the frame 212. An accommodating space 2110 for accommodating the battery 22 and the control circuit board is formed inside the housing 211. The frame 212 is inserted into the mounting hole 2111 and can be in interference fit with the housing 211. The housing 212 is used for housing the extractor 10 and can cover the mounting opening 2111, so that the receiving space 2110 forms a closed space, and can be used for mounting the heating body 30 and supporting the heating body 30.

In some embodiments, the housing 212 includes a guide 2121 and a support 2122. The support portion 2122 is disposed at one end of the guide portion 2121 and integrally formed with the guide portion 2121, and is configured to be inserted into the housing 211 through the mounting opening 2111, and has a cross-sectional shape and size compatible with the cross-sectional shape and size of the housing 211. The support 2122 may be in an interference fit with the housing 211 for supporting the sleeve 12 when the extractor 10 is in the first position, thereby limiting the sleeve 12. The guide portion 2121 is provided on the support portion 2122 and may protrude from the mounting opening 2111 of the housing 211. The cross-sectional dimension of the guide 2121 may be smaller than the cross-sectional dimension of the support 2122. In some embodiments, the guide 2121 is formed with a first cavity 2123 on an inner side and a second cavity 2124 on an outer side. The first and second cavities 2123, 2124 may be disposed side-by-side. The first cavity 2123 may be in communication with the receiving space 2110 to form a closed cavity for mounting a control circuit board. The second cavity 2124 is a cavity having an opening for receiving the fixing tube 123 and mounting the heating body 30.

In some embodiments, the heating body 30 is centrally disposed on the bottom wall of the second cavity 2124 and partially disposed in the second cavity 2124, and the heating body 30 can be coaxially disposed with the second cavity 2124. The heating body 30 may be in a longitudinal sheet shape, and includes a sheet-shaped body 31, a tip portion 32 disposed at one end of the sheet-shaped body 31, and a limiting portion 33 disposed at the other end of the sheet-shaped body 31. The pointed tip 32 facilitates the placement of the heating body 30 from the perforations 1233 of the support wall 1232 through and into the bottom of the aerosol-forming substrate 20 located in the receiving cavity 1230. The limit part 33 can be used for limiting and installing the whole heating body 30 and connecting and fixing the heating body 30 and the frame 212. The cross-sectional dimension of the limiting portion 33 is larger than the cross-sectional dimension of the sheet-like body 31, and specifically, the width of the limiting portion 33 may be larger than the width of the sheet-like body 31. Of course, it will be appreciated that in other embodiments, the heating body 30 is not limited to being sheet-like, and in other embodiments, the heating body 30 may be columnar.

In some embodiments, the body 21 and the extractor 10 are provided with a stop structure 40 that prevents the extractor 10 from being separated from the body 21 in the second position, so that the extractor 10 is always connected to the body 21 when the aerosol-forming substrate 200 is inserted and removed. In some embodiments, the spacing structure 40 includes a first spacing tab 41 and a second spacing tab 42. In some embodiments, the first limit protrusion 41 is disposed on an inner sidewall of the sleeve 121. The first limiting protrusion 41 is located at the middle lower portion of the sleeve 121, that is, near the sleeve opening 1211. The number of the first limiting protrusions 41 is two, and the two first limiting protrusions 41 are disposed on two opposite sides of the sleeve 121. Of course, it will be appreciated that in other embodiments, the first limit projection 41 is not limited to two, and may be one or more than two. The second limiting protrusion 42 is disposed on an outer sidewall of the frame 212 and can be matched with the first limiting protrusion 41. Specifically, in some embodiments, the second limiting protruding portions 42 are disposed on the outer side wall of the guide portion 2121 and may be disposed in one-to-one correspondence with the first limiting protruding portions 41. The second limiting protrusion 42 may be located at a middle upper portion of the guide portion 2121, that is, near an end surface of the guide portion 2121 away from the end of the support portion 2122. When the extractor 10 is moved to the second position by the predetermined distance toward the end far from the support 2122 by the aerosol-forming substrate 200, the second limiting protrusion 42 applies a force to the first limiting protrusion 41 in the opposite direction, which is greater than the clamping force applied to the aerosol-forming substrate 200 by the dust cap 131 and/or the fixing member 124, so that when the user continues to pull out the aerosol-forming substrate 200, the aerosol-forming substrate 200 is pulled out against the clamping force applied to the aerosol-forming substrate 200 by the dust cap 131 and/or the fixing member 124, and the extractor 10 stops moving under the blocking of the second limiting protrusion 42, so that the extractor cannot be separated from the body 21. In some embodiments, the set distance may be 2-10mm.

In some embodiments, the aerosol generating device further comprises a reset mechanism 50. The reset mechanism 50 is disposed on the extractor 10 and the body 21, and is used for driving the extractor 10 to slide after the aerosol-forming substrate 200 is pulled out of the extractor 10, so that the extractor 10 returns to the first position from the second position, and reset is achieved. In some embodiments, the reset mechanism 50 may include a magnetic assembly including a first magnetic member 51 and a second magnetic member 52, where the first magnetic member 51 is disposed in the extractor 10, and the second magnetic member 52 is disposed in the body 211 and corresponds to the first magnetic member 51. Specifically, in some embodiments, the first magnetic member 51 may be mounted between the sleeve 121 and the end cover 122, and in particular, may be received in a receiving groove 1213 disposed opposite the sleeve 121 and the end cover 122. The second magnetic member 52 is disposed inside the top wall of the frame 212, and is capable of being matched with the first magnetic member 51. When the extractor 10 is moved to the second position and the aerosol-forming substrate 200 is pulled out of the extractor 10, the first magnetic member 51 magnetically attracts the second magnetic member 52, thereby returning the extractor 10 from the second position to the first position.

As further shown in fig. 1-5, when the aerosol-generating device 100 is in use, the extractor 10 can be positioned in the first position, and the cover 11 of the extractor 10 is in contact with the end surface of the mounting opening 2111 of the housing 211. The aerosol-forming substrate 200 may be inserted from the insertion/extraction port 113 of the extractor 10 by manual insertion so that the medium section of the aerosol-forming substrate 200 is placed in the receiving cavity 1230, and at the same time, the heating body 30 may be inserted into the aerosol-forming substrate 200 from the bottom end portion or the whole of the aerosol-forming substrate 200 and heat the aerosol-forming substrate 200 in the energized state.

When the aerosol-forming substrate 200 needs to be pulled out, the aerosol-forming substrate 200 can be directly pulled out, so that the whole extractor 10 is driven to move towards one end of the support portion 2122 far away from the rack 212, when the extractor 10 is located at the second position, the second limiting protrusion 42 is abutted against the first limiting protrusion 41, at this time, part of the heating body 30 is withdrawn from the aerosol-forming substrate 200 and the accommodating cavity 1230, part of the heating body 30 is remained in the aerosol-forming substrate 200, and then the aerosol-forming substrate 200 is continuously pulled out, the aerosol-forming substrate 200 can be separated from the heating body 30 and pulled out from the extractor 10, and the extractor 10 does not move towards the direction far away from the support portion 2122 any more, but moves towards the direction near the support portion 2122 under the action of the first magnetic member 51 and the second magnetic member 52, namely returns to the first position from the second position.

The aerosol generating system can directly extract the aerosol forming substrate 200 without pushing the cover 11, thus solving the problem that the residue falls when a part of users forget to push the cover 21 after sucking and directly pull out the aerosol forming substrate 200, and the aerosol generating system is simpler to operate, simpler in structure and lower in manufacturing cost compared with pushing the cover 11 to take out the aerosol forming substrate 200.

It is to be understood that the above examples only represent preferred embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the invention; it should be noted that, for a person skilled in the art, the above technical features can be freely combined, and several variations and modifications can be made without departing from the scope of the invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
