In some alternative implementations, the aerosol-generating article is prepared to have the shape of a conventional cigarette or cigar.

In a preferred embodiment, the heater 22 comprises a magnetically susceptible material such as grade 430 stainless steel (SS 430), or grade 420 stainless steel (SS 420), or an iron-nickel alloy material (e.g., permalloy) that generates heat in a varying magnetic field, such that the heater generates heat in the varying magnetic field, and thereby self-heats due to eddy currents and hysteresis in the varying magnetic field, and conducts and/or radiates heat to the aerosol-generating article to heat the aerosol-generating article. Correspondingly, the aerosol generating device also comprises a magnetic field generator, such as an induction coil, which is used for generating a changing magnetic field under alternating current, and the circuit board is connected with the electric core and the induction coil and can convert the direct current output by the electric core into the alternating current, preferably, the frequency of the alternating current is between 80KHz and 400KHz; more specifically, the frequency may be in the range of approximately 200KHz to 300 KHz.

In a preferred embodiment, the heater 22 has an infrared coating thereon that is capable of being excited by direct current supplied by the cell 241 to radiate infrared light to heat at least part of the aerosol-generating article 1. The infrared coating is preferably composed of oxides of at least one metal element of Mg, al, ti, zr, mn, fe, co, ni, cu, cr, etc., which radiate far infrared rays having heating effect above when power is supplied; the preparation method can be that the metal oxide is obtained by spraying the metal oxide on the surface of the substrate by means of plasma spraying and then solidifying. The aerosol-generating article 1 may generate heat when the infrared coating emits infrared light towards the aerosol-generating article 1, and the aerosol may be generated when the heating temperature reaches a predetermined temperature.

In a preferred embodiment, the heater 22 is made of, or comprises, a resistive conductive material such as an iron-chromium-aluminum alloy, a nickel-chromium alloy, a nickel-iron alloy, platinum, tungsten, silver, a conductive ceramic, or a conductive material containing at least one of the foregoing, such that when electrically conductive, heat is generated by resistance to heat the aerosol-generating article 1 to volatilize at least one component of the aerosol-generating article 1 to form an aerosol.

Referring to fig. 3 and 4, the heater 22 is generally in the shape of a pin or needle or token, which in turn is advantageous for insertion into the aerosol-generating article 1. Meanwhile, the heater 22 may have a length of about 12 to 19 mm and a diameter of 2.0 to 2.6 mm. The cross section of the device can be circular, straight-line, oval or polygonal, etc. In other embodiments, the heater 22 may be generally cylindrical or other structure that can be disposed at the periphery of the aerosol-generating article 1 to conduct, radiate heat from the periphery of the aerosol-generating article 1 to the aerosol-generating article 1, with at least part of the suit 23 being located between the heater 22 and the aerosol-generating article 1, so that stiction of the heater 22 to the aerosol-generating article 1 can be avoided, enabling extraction of the aerosol-generating article 1 directly through grasping the second exposed section 12 of the aerosol-generating article 1.

Referring to figure 2, the aerosol-generating article 1 may be a conventional aerosol-generating article comprising a first section 11 and a second section 12, the first section 11 being capable of being inserted into the receiving cavity of the aerosol-generating device during use, the second section 12 remaining external to the aerosol-generating device. The first section 11 has at least one component selected from tobacco, flavor, aroma, herbal medicine, etc. for generating aerosol by the heater 22. The second segment 12 has a mouthpiece 121 for holding a mouthpiece by which the mouthpiece 121 is drawn to draw aerosol generated by the aerosol-generating article 1 into the mouthpiece. In some embodiments, the first section 11 comprises an aerosol-forming substrate section 111 and a first cooling section 112, the aerosol-forming substrate section 111 being insertable into and in contact with the heater 22 and being capable of generating an aerosol under the influence of the heater 22, the first cooling section 112 being free of substances capable of generating volatiles under the influence of the heater 22, the distance between the lowermost end of the first cooling section 112 and the lowermost end of the aerosol-forming substrate section 111 being greater than the depth of insertion of the heater 22 into the first section 11 such that the first cooling section 112 is outside the contact range of the heater 22; the first cooling section 112 has the function of cooling the aerosol, and prevents the temperature of the aerosol entering the mouth from being too high to scald the mouth. In some embodiments, the second section 12 comprises a suction nozzle 121 and a second cooling section 122, the suction nozzle 121 is disposed at the uppermost part, and the second cooling section 122 mainly has a cooling function to prevent the aerosol entering the mouth from being too hot to scald the mouth; of course, a third section may be provided between the first section 11 and the second section 12, and the first section 11 and the second section 12 are connected by the third section, so that when the second section 12 is applied with the extracting force, the first section 11 can move along the extracting direction in response to the extracting force under the traction of the third section, and the third section may have a cooling function, and when the suction nozzle 121 or the third section is long enough, or the cooling effect of the first cooling section 112 and/or the third section is good enough, the second cooling section 122 may not be needed.

In the embodiment shown in figures 2-4, the aerosol-generating device comprises a body 2, the body 2 comprising a housing 21, the interior of the housing 21 having a cavity forming a receiving cavity containing at least part of the aerosol-generating article 1. The main body 2 further includes a protector 23, and the protector 23 protects the aerosol-generating article 1 so that the aerosol-generating article 1 does not break or break when the aerosol-generating article 1 is detached by relative movement with the heater 22, thereby ensuring that the aerosol-generating device can be completely pulled out of the aerosol-generating article 1. At the same time, under the protection of the protector 23, the user can extract the aerosol-generating article 1 by directly grasping the second segment 12 exposed outside the aerosol-generating device, so that the aerosol-generating article 1 is detached from the aerosol-generating device.

Referring to fig. 2-4, the housing 21 is made of a material that is resistant to high temperature and has a heat insulation function, such as PEEK, and is disposed around the receiving cavity to prevent the high temperature in the receiving cavity from radiating from the side and burning the hand, and the housing 21 helps to maintain the high temperature in the receiving cavity, thereby reducing energy consumption. In some embodiments, to increase the insulating effect of the housing 21, the housing 21 has a cavity in its wall, which may be either vacuum or filled with air, and which is disposed around the receiving cavity to increase the insulating and heat preserving effect.

Referring to fig. 2-4, the brace 23 is capable of following the first segment 11 through a stroke in response to the extraction force applied to the second segment 12, the stroke beginning at the first position and ending at the second position, and the stroke path may be linear, spiral, or bent, curved, etc.

In particular, the protector 23 may provide a movable connection between the first segment 11 and the shell 21 delimiting the receiving cavity, namely: the suit 23 is movably connected with the housing 21 such that the suit 23 can be moved between a first position and a second position on the body 2, the aerosol-generating article 1 is connected with the suit 23, and the connecting force between the aerosol-generating article 1 and the suit 23 is greater than the connecting force between the suit 23 and the housing 21, such that when an extraction force is applied on the aerosol-generating article 1, the suit 23 can follow the movement of the aerosol-generating article 1 from the first position to the second position, while the aerosol-generating article 1 moves with its stroke at least from the first position to the second position during this movement of the suit 23 from the first position to the second position. The first position may be an operating position in which at least part of the heater 22 is located inside the aerosol-generating article 1, the heater 22 heating the aerosol-generating article 1 such that the aerosol-generating article 1 produces an aerosol with the aerosol-generating article 1 being located in the first position, the first position may be a starting point of travel of the suit 23 and/or the aerosol-generating article 1 on the body 2 during extraction of the aerosol-generating article 1; the second position is the end of travel of the suit 23 over the body 2 from the first position during extraction of the aerosol-generating article 1, between which first and second positions (including over the first and second positions) the aerosol-generating article 1 remains connected to the suit 23 at all times. During movement of the suit 23 from the first position to the second position, the first section 11 received in the receiving cavity is also moved from the first position to at least the second position, so that the heater 22 gradually exits the first section 11, and thus the adhesion between the heater 22 and the first section 11 is loosened, facilitating the extraction of the first section 11 from the heater 22, while at the same time the suit 23 protects the first section 11 by defining the side walls of the first section 11 and/or by jacking against the bottom of the first section 11, etc., preventing it from breaking or breaking away slag during the exit from the receiving cavity and/or the suit, facilitating the complete extraction of the aerosol-generating article 1 from the aerosol-generating device. The stroke of the suit 23 during extraction of the aerosol-generating article 1 is a stroke from the first position to the second position, the stroke of the aerosol-generating article 1 including a stroke from the first position to the second position and also including a stroke to release the connection with the suit.

In a preferred embodiment, the heater 22 is at least partially located within the first section 11 when the shield 23 is in both the first position and the second position, and in particular, the heater 22 is at least partially located within the aerosol-forming substrate section 111 in the first section 11 when the shield 23 is in both the first position and the second position, i.e., the first section 11 remains attached to the heater 22 in both the first position and the second position, and the first section 11 is not completely detached from the heater 22. The reasons for such design include: 1. between the first position and the second position, the protector 23 can effectively prevent the first stage 11 from being broken or broken during the process of debonding from the heater 22 by protecting the first stage 11, and can ensure that the aerosol-generating article 1 remains intact during the process of debonding from the heater 22; 2. the first section 11 is enough to release the adhesion formed between the first section 11 and the heater 22 due to high temperature during the process of moving from the first position to the second position, after the adhesion is released, the first section 11 will not break or break during the process of separating from the heater 22, so that the integrity of the first section 11 can be continuously maintained, so that the first section 11 is allowed not to separate from the heater 22 in the second position; 3. by making the axial linear distance between the first and second positions less than the depth of the first section 11 when the heater 22 is inserted in the first position, the linear distance between the first and second positions is limited, avoiding an increase in the volume of the receiving chamber due to the provision of the protector 23, which is advantageous for miniaturization of the aerosol generating device.

In a preferred embodiment, the brace 23 protects the side wall of the first section 11 by providing a sleeve 231 to protect the first section 11 from breaking or chipping the first section 11. In the embodiment shown in fig. 2 and 3, the suit 23 includes a through hole 233 for the heater 22 to pass through into the interior of the first section 11, and a sleeve 231 surrounding the through hole 233 and extending axially, the interior of the sleeve 231 being adapted to receive the first section 11. The sleeve 231 is tubular, and its axial lower end can be completely opened, thereby forming the through hole 233; the sleeve 231 supports and protects the side wall of the first section 11 during the process of detackifying the first section 11 from the heater 22, preventing the side wall of the first section 11 from breaking or cracking, and at the same time, the sleeve 231 is connected to the side wall of the first section 11, and when the extraction force is applied to the second section 12, the extraction force is transmitted through the second section 12 and acts on the sleeve 231 through the side wall of the first section 11, so that the sleeve 231 can move from the first position to the second position.

The axial length of the sleeve 231 is at least greater than the length of the aerosol-forming substrate segment 111 in the first segment 11, the aerosol-forming substrate segment 111 in the first segment 11 may be fully contained within the sleeve 231, and since the heater 22 primarily bakes the aerosol-forming substrate segment 111, the baked aerosol-forming substrate segment 111 is more fragile than the first cooling segment 112, and for better protection of the aerosol-forming substrate segment 111, it is preferred that at least part of the first cooling segment 112 is located within the sleeve 231 and is in tight fitting connection with the sleeve 231, such that upon upward extraction of the aerosol-generating article 1 by grasping the second segment 12, the side walls of the first cooling segment 112 are subjected to the primary forces of interconnection between the first segment 11 and the sleeve 231 and moving the protector 23 from the first position to the second position, thereby protecting the side walls of the aerosol-forming substrate segment 111 against fracture or breakage.

Referring to fig. 2 and 3, the sleeve 231 is provided with a close-fitting portion 234 extending along the radial direction of the sleeve 231 toward the center of the sleeve 231, the close-fitting portion 234 is used for being tightly fitted with the first section 11, and can form a force capable of gripping the side wall of the first section 11 with the first section 11, and in particular, at least partially tightly fitted with the first cooling section 112 in the first section 11, so that when the second section 12 is applied with an upward extraction force, the protector 23 can grip the first section 11 by friction force, so as to be capable of following the first section 11 to move along the extraction direction, i.e., to move toward the second position. Under the action of the interference fit 234, the brace 23 can remain relatively stationary and in synchronous motion with the first segment 11 for a certain stroke, i.e., at least in the first position, the brace 23 has the same travel speed as the first segment 11; it is of course not excluded that the first section 11 can also be moved in the direction of the second position along the side wall of the sleeve 23 while both the protector 23 and the first section 11 are moved in the direction of the second position by the extraction force on the second section 12, i.e. the travelling speed of the first section 11 is greater than the travelling speed of the protector 23 by the extraction force. When the travelling speed of the first segment 11 in the extracting direction is greater than the travelling speed of the sleeve 231, there is a relative movement between the first segment 11 and the sleeve 231 which is separated from each other. For example, when the supporter 23 is in the second position, the traveling speed in the extracting direction becomes 0, and the traveling speed of the first stage 11 in the extracting direction is greater than 0, so that the first stage 11 can make a motion of being separated from the sleeve 231. In an alternative embodiment, the velocity of travel of the brace 23 in the direction of extraction at the second position drops to 0, and can be maintained at 0 until the brace 23 automatically moves in the direction of extraction toward the first position after the first segment 11 is completely disengaged from the brace 23, i.e., automatically resets after being completely disengaged from the first segment. In another alternative embodiment, the guard 23 can be moved back towards the first position immediately after the travel speed in the direction of extraction in the second position has dropped to 0, under the influence of a repulsive force or other force.

In some embodiments, the tight fitting portion 234 may have a larger coefficient of friction, so that when the tight fitting portion 234 contacts the sidewall of the first segment 11, a larger static friction force may be formed between the tight fitting portion 234 and the sidewall of the first segment 11, and thus the tight fitting portion 234 may not be a protrusion extending toward the center of the sleeve 231.

In a preferred embodiment, the tight fitting portion 234 is made of a flexible material such as silicone rubber, etc. when the first segment 11 is inserted into the sleeve 231, the tight fitting portion 234 is in interference fit with the first segment 11, so as to achieve a tight fitting connection and generate a tight fitting force such as friction force or elastic force, etc. The tight fitting action of the fitting portion 234 on the first section 11 is greater than the action between the sleeve 231 and the housing 21 and the weight of the suit 23, so that the suit 23 can be pulled from the first position to the second position, while the tight fitting action is less than the maximum bearing force in the axial direction of the aerosol-generating article 1, so that the aerosol-generating article 1 is not pulled apart when the aerosol-generating article 1 is extracted.

Referring to fig. 7, the tight fitting portion 234 includes a barb structure 2341 extending along a radial direction and downward inclination of the sleeve 231, the barb structure 2341 is located on a lower end surface of the tight fitting portion 234, an upper end surface of the tight fitting portion 234 may extend downward, i.e. following a direction of inserting the first segment 11 into the sleeve 231, so as to facilitate inserting the first segment 11 into the sleeve 231, and an inner portion of the barb structure 2341 sleeve 231 is inclined downward or located inside the sleeve 231 and extends radially, and faces a direction opposite to a direction of withdrawing the first segment 11 from the first sleeve 231, so as to help prevent the first segment 11 from withdrawing the sleeve 231 and increase a force between the sleeve 231 and the first segment 11.

Referring to fig. 7, the sleeve 231 includes a first sleeve 2312 and a second sleeve 2313, the second sleeve 2313 is made of a flexible material such as silicone or the like and has a larger friction coefficient than the first sleeve 2312, the second sleeve 2313 can be integrally formed with the fitting 234 or directly connected to the first section 11 instead of the fitting 234 and generates a force for obstructing the first section 11 from exiting the sleeve 231, and the first sleeve 2312 is made of a hard material such as PEEK or the like and partially extends to the area of the second sleeve 2313 to connect and support the second sleeve 2313. The second sleeve 2313 extends axially and may be connected to a side wall of the first cooling section 112 and/or a portion of the side wall of the aerosol-forming substrate section 111, e.g. there may be a portion of the interference fit 234 connected to the side wall of the first cooling section 112 and the remainder of the interference fit 234 connected to the side wall of the aerosol-forming substrate section 111.

In a preferred embodiment, the brace 23 protects and supports the bottom of the first section 11 by providing a mounting 232, and the mounting 232 supports the first section 11 upwardly to prevent breaking or dropping debris during debonding of the first section 11 from the heater 22. In the embodiment shown in fig. 2 and 3, the shoe 232 extends radially from the bottom of the sleeve 231, and a through hole 233 for the heater 22 to pass through extends through the shoe 232 and may be located in the center of the shoe 232.

The aperture of the through hole 233 may be slightly larger than the outer diameter of the heater 1 so that when the supporter 23 is moved to the second position, i.e., the heater 22 is retracted from the through hole 233 relative to the supporter 23, the edge of the through hole 233 can scrape off the residue of the aerosol-generating article 1 adhering to the surface of the heater 22 to clean the heater 22.

In order that the aerosol will be prevented from entering the receiving chamber by air convection into the region of the suit other than the interior thereof and thereby contaminating that region, in the embodiment shown in figure 3 the main body further comprises an insertion opening 25 through which the first segment 11 is inserted into the receiving chamber after having passed through the insertion opening 25. The edge of the insertion opening 25 has at least one recess 251, and the recess 251 is used for air to pass through, so that the air can enter the receiving cavity through the recess 251. Referring to fig. 3, the recess 251 has a plurality of recesses which are uniformly or symmetrically distributed on the edge of the insertion opening 25, so that the air can enter the receiving cavity from a plurality of directions or positions.

Referring to fig. 3, the sleeve 231 is provided with a first air passage communicating with the insertion opening 25, the base 232 is provided with a second air passage communicating with the first air passage, the recess 251, the first air passage and the second air passage on the insertion opening 25 provide air passages for air to enter the aerosol-generating article 1, and the air can enter the aerosol-generating article 1 from the side wall of the aerosol-generating article 1 and/or enter the aerosol-generating article 1 from the bottom of the aerosol-generating article 1.

In a further embodiment, referring to fig. 3, the bottom support 232 has a circumferential rib 235 circumferentially disposed around the periphery of the through hole 233, the rib 235 extends axially to support the bottom of the aerosol-generating article 1, and the secondary air channel is defined by the bottom support 232 and the rib 235. Referring to fig. 3, the inner wall of the sleeve 231 has a groove 2311 extending along the axial direction, the upper end of the groove 2311 is communicated with the recess 251 on the insertion opening 25, the lower end is connected with the bottom support 232 so as to be communicated with the second air passage, and the first air passage is defined by the groove 2311; the grooves 2311 may have a plurality of strips, and may be symmetrically or uniformly distributed on the inner sidewall of the sleeve 231. Specifically, referring to fig. 7, the first sleeve 2312 is provided with a plurality of meshes for the tight fitting portion 234 to pass through and extend into the first sleeve 2312, the second sleeve 2313 is provided at a partial periphery of the first sleeve 2312, and the groove 2311 is provided on an inner side wall of the first sleeve 2312.

When drawn through the mouthpiece 121, air enters the receiving cavity through the depression 251 on the insertion opening 25 and passes through the first air passage into the second air passage, then from the bottom of the aerosol-generating article 1 through the second air passage into the first end of the aerosol-generating article 1 and finally through the mouthpiece 121 on the second segment 12 into the mouth, although when the aerosol-generating article 1 has air holes in its side walls or when the side walls of the aerosol-generating article 1 are air permeable, air in the first air passage may pass through the side walls of the aerosol-generating article 1 into the interior of the aerosol-generating article 1.

In the embodiment shown in fig. 2 and 3, the sleeve 231 has a complete sidewall, so it is necessary to form a groove 2311 on the sidewall of the sleeve 231 to constitute at least part of the first air passage. In other embodiments, the sidewall of the sleeve 231 is a hollow sidewall, which may have a hollow hole, or the sidewall of the sleeve 231 includes one or more claw-like or sheet-like or column-like structures extending upward from the bottom support 232, which are disposed on the periphery of the first section 11 and connected to at least a portion of the sidewall of the first section 11. Air may enter the interior of the sleeve 231 and then the first section 11 through the hollowed-out holes, or through the gaps between the claw-like or sheet-like or cylindrical structures.

The brace 23 can be moved from the first position to the second position by sliding relative to the housing 21. Referring to fig. 4 and 5, the housing 21 is slidably connected to the sleeve 231.

In a preferred embodiment, as shown in fig. 4 and 5, the shape of the inner wall of the housing 21 is adapted to the shape and size of the outer wall of the brace 23, the outer wall of the brace 23 fits the inner wall of the housing 21, and the brace 23 slides along the inner wall of the housing 21 when the brace 23 is moved to the second position or the first position, hi one embodiment, as shown in fig. 4, the outer wall of the brace 23 is in smooth contact with the inner wall of the housing 21 to reduce the sliding friction between the outer wall of the brace 23 and the inner wall of the housing 21, and to ensure that the friction between the outer wall of the brace 23 and the inner wall of the housing 21 is less than the tightening force between the aerosol-generating article 1 and the tightening portion 234, such that when the aerosol-generating article 1 is extracted by grasping the second segment 12, the brace 23 can follow the aerosol-generating article 1 and can move together to the second position. To further reduce the resistance to movement when the outer wall of the brace 23 and the inner wall of the housing 21 move relative to each other, a ball may be provided between the outer wall of the brace 23 and the inner wall of the housing 21 so that the outer wall of the brace 23 and the inner wall of the housing 21 are in rolling contact. In another embodiment, to further reduce the resistance to movement when the outer wall of the brace 23 and the inner wall of the housing 21 move relative to each other, the contact area between the outer wall of the brace 23 and the inner wall of the housing 21 can be reduced, such as providing a rib on the outer wall of the brace 23 that smoothly connects to the inner wall of the housing 21 via the rib, or providing a rib on the inner wall of the housing 21 that smoothly connects to the outer wall of the brace 23 via the rib, thereby reducing friction.

In another preferred embodiment, as shown in fig. 5, the housing 21 has a first sliding portion 211, the sleeve 231 has a second sliding portion slidably connected to the first sliding portion 211, one of the first sliding portion 211 and the second sliding portion is a guide rail for guiding the sliding direction, and the other is a slider or a slide groove for sliding along the guide rail, and the sliding direction is defined by the guide rail, so that the protector can be prevented from deviating from the orbital motion. The guide track may be linear or helical, and in order to simplify the trajectory of the guard 23 in the receiving cavity, it is preferred that the guide track extends parallel to the axial direction of the receiving cavity, such that the guide track is linear and prevents the guard 23 from rotating in the receiving cavity, thereby reducing the torque between the guard 23 and the sidewall of the aerosol-generating article 1 and protecting the aerosol-generating article 1 from breaking or breaking. Of course, in other embodiments, other mechanisms are provided on the main body 2 or the brace 23 to prevent rotation of the brace 23 when moving from the first position to the second position. It is certainly not excluded that in some embodiments there is no contact between the brace 23 and the housing 21, e.g., the brace 23 may be at least partially suspended within a receiving cavity in the housing 21.

In some embodiments, the brace 23 can extend at least partially out of the receiving cavity when in the first position or the second position, or in a position between the first position and the second position, to facilitate cleaning and maintenance thereof.

However, in order to prevent the user from accidentally touching the protector 23 and prevent the protector 23 from burning the user, the protector 23 may be hidden inside the aerosol generation device and not exposed. In the embodiment shown in fig. 3, the shield 23 does not extend beyond the receiving cavity in both the first position and the second position, and does not extend beyond the receiving cavity in other positions between the first position and the second position, so that the shield 23 cannot be touched by a user without dismantling the machine, thereby protecting the user and increasing the safety factor of the aerosol-generating device.

The guard 23 may be retained in the receiving cavity by providing a stop to prevent the guard 23 from being exposed beyond the receiving cavity outside the aerosol-generating device. In the embodiment shown in fig. 3, a first stop 26 is provided on the main body 2 and a second stop 236 is provided on the guard, the first stop 26 being used to prevent the second stop 236 from continuing to travel in the extraction direction, thereby stopping the guard 23 at the second position.

In an alternative embodiment, when the suit 23 is in the second position, the first stop 26 and the second stop 236 are in contact with each other, the first stop 26 is located downstream of the travel of the second stop 236 in the extraction direction, and the first stop 26 prevents the suit 23 with the second stop 236 from continuing to travel by contacting the stops. The suit 23 may stay in the second position after reaching the second position to wait for a new aerosol-generating article 1 to be inserted into the suit 23 and, following insertion of a new aerosol-generating article 1, move towards the first position under the urging of the new aerosol-generating article 1, and finally stay in the first position whereupon the heater 22 may then heat the aerosol-generating article 1. The first stop portion 26 and the second stop portion 236 are both magnetic members, or are each a magnetic material and a magnetic member, where the magnetic member includes a permanent magnet, an electromagnet, or the like that can generate a magnetic field, and where the magnetic material includes a material that can be attracted by the magnetic member, such that when the first stop portion 26 and the second stop portion 236 are close to each other, they have an attractive force therebetween, and when the distance between the first stop portion 26 and the second stop portion 236 is less than a threshold value, the attractive force is greater than the weight of the brace 23 itself, so that the brace 23 can be held in the second position after the aerosol generating article 1 is pulled out of the brace 23. When the suit 23 with the aerosol-generating article 1 inserted is in the first position, the attractive force between the first stop 26 and the second stop 236 is less than the weight of the suit 23 or less than the sum of the weights of the suit 23 and the aerosol-generating article 1, so that the suit 23 and the aerosol-generating article 1 can remain in the first position. By applying the extraction force to the second segment 12 again by the suction force, the supporter 23 and the aerosol-generating article 1 can be moved from the first position to the second position more easily and easily, so that a smaller extraction force can be used, the difficulty of extraction can be reduced, the force acting between the supporter 23 and the sidewall of the aerosol-generating article 1 can be reduced when the aerosol-generating article 1 is moved from the first position to the second position, and the aerosol-generating article 1 can be further prevented from being broken or crushed when the aerosol-generating article is moved from the first position to the second position. In a further embodiment, when the aerosol-generating article 1 is gradually reduced in weight by aerosol production in the first position, when the weight of the aerosol-generating article 1 is reduced to a threshold value (e.g. when the aerosol produced no longer meets the per puff requirement, or the aerosol cannot be produced any more), the suction force between the first stop 26 and the second stop 236 is greater than the sum of the weight of the brace 23 and the aerosol-generating article 1 in that state, so that the brace 23 can cause the aerosol-generating article 1 to automatically move from the first position to the second position, giving the user a better experience.

On the premise that the supporter 23 can be held in the second position after the aerosol-generating article 1 is pulled out of the supporter 23, the main body 2 may include a sense switch, and when the sense switch 3 senses that the supporter 23 returns to the first position, the sense switch is triggered to conduct the electrical connection between the circuit board 242 and the heater 22 to generate heat in the heater 22, and the method of conducting the heater includes: 1. after the inductive switch 3 is triggered, a signal is sent to a circuit switch between the heater 22 and the power supply assembly 24, and the circuit switch is directly controlled to be closed, so that the electric connection between the heater 22 and the power supply assembly 24 is conducted; or 2, after the induction switch 3 is triggered, sending a signal to a processor in the aerosol generating device, and outputting a new signal by the processor to control a circuit switch between the heater 22 and the power supply assembly 24 to be closed so as to conduct the electric connection between the heater 22 and the power supply assembly 24; or when the inductive switch 3 is triggered, the aerosol generating device is automatically started, so that the aerosol generating device is in a standby state (even if the heater 22 is in a pre-starting state), when the aerosol generating device is in the standby state, the aerosol generating device can be controlled through keys and the touch screen 27 arranged on the aerosol generating device, for example, the heater 22 is controlled to generate heat, or when the aerosol generating device is in the standby state, the aerosol generating device can be controlled through a remote controller to execute corresponding commands, for example, the heater 22 is controlled to generate heat, and the condition that the protective tool 23 is in the first position and is set as the trigger inductive switch 3 can be avoided, so that children and the like are not suitable for groups to start the aerosol generating device by mistake.

The inductive switch 3, which may be a piezoelectric switch, is arranged at the bottom of the receiving cavity and is pressed or pressed by the brace 23 when the brace 23 is in the first position, thereby being triggered; the inductive switch 3 may comprise a magnetically inductive switch (e.g. a hall switch or a magnetic flux sensor, etc.) which is triggered by a magnetic field strength exceeding a certain threshold: in an alternative, the inductive switch 3 is disposed on the main body 2, and is disposed corresponding to the first position, the protective equipment 23 is disposed with a first magnetic member 41 (such as a magnet) for generating a magnetic field, when the protective equipment 23 is closer to the first position, the magnetic field intensity generated by the first magnetic member 41 received by the inductive switch 3 is stronger, when the intensity reaches the induction threshold of the inductive switch 3, the magnetic inductive switch 3 is triggered, and in the process of extracting the aerosol-generating article 1, the protective equipment 23 moves from the first position to the second position and gradually gets away from the inductive switch 3, so that the magnetic field intensity sensed by the inductive switch 3 is gradually weakened, and when the intensity is smaller than the induction threshold of the inductive switch 3, the magnetic inductive switch 3 is turned off; in another alternative, the inductive switch 3 is disposed on the supporter 23, because the inductive switch 3 is smaller and lighter, so as not to greatly increase the weight of the supporter 23, the first magnetic member 41 (e.g., a magnet) is disposed on the main body 2 corresponding to the first position, when the supporter 23 is closer to the first position, the intensity of the magnetic field generated by the first magnetic member 41 received by the inductive switch 3 is stronger, when the intensity reaches the inductive threshold of the inductive switch 3, the inductive switch 3 is triggered, otherwise, the inductive switch 3 is turned off; in an alternative arrangement, the inductive switch 3 is provided on the body 2, arranged to correspond to the first position, and a trigger is provided within the aerosol-generating article, the trigger being sensed by the inductive switch 3 when the first section 11 is in the first position, such that the inductive switch 3 is triggered. It is of course not excluded that other inductive switches 3 can be determined whether the brace 23 has reached the first position and can be triggered when the brace 23 has reached the first position.

In another alternative embodiment, the brace 23 is in the second position with the first stop 26 and the second stop 236 in no contact or direct contact with each other, such as: the first and second stops 26, 126 are both magnetic and, when brought into proximity with each other, the first and second stops 26, 126 have a repulsive force between them which is greater than the interaction force between the suit 23 and the aerosol-generating article 1, which results in the second stop 236 being unable or difficult to contact the first stop 26 while ensuring that the aerosol-generating article 1 can be pulled away from the suit 23, and the suit 23 can automatically reset, i.e. automatically return from the second position to the first position, after the aerosol-generating article 1 has completely detached from the suit 23 under the action of this repulsive force and the own weight of the suit 23.

In a more preferred embodiment, referring to fig. 6, the main body 2 includes a first magnetic member 41 and a second magnetic member 42, the first magnetic member 41 (e.g., a magnet) and the second magnetic member 42 (e.g., a magnet) can provide a magnetic field, and the first magnetic member 41 and the second magnetic member 42 have a magnetic force when they are close to each other, the inductive switch 3 is disposed on the main body 2 corresponding to the first position, the first magnetic member 41 is disposed on the supporter 23; a second magnetic part 42 is arranged on the main body 2 corresponding to the second position; when the supporter 23 is located at the first position, the magnetic field intensity applied by the first magnetic member 41 to the magnetic induction switch 31 triggers the induction switch 3, and when the supporter 23 is located at the second position, the magnetic attraction force between the first magnetic member 41 on the supporter 23 and the second magnetic member 42 on the main body 2 holds the supporter 23 at the second position (therefore, in some embodiments, the second magnetic member 42 may be replaced by a magnetic induction material that can be attracted by the first magnetic member 41), and of course, the second magnetic member 42 may be disposed on the first stopper portion 26 or in the vicinity of the first stopper portion 26.

In another alternative embodiment, there is a resilient member, such as a spring, between the first stopper 26 and the second stopper 236, or at least one of the first stopper 26 and the second stopper 236 is a resilient member, when the protector 23 is located at the second position, the first stopper 26 and the second stopper 236 are resiliently connected, and the resilient member has a buffering and anti-collision function, so as to avoid that the second stopper 236 hits the first stopper 26 when the extraction force is too large, which leads to sudden stop of movement, and then leads to the aerosol-generating article 1 breaking or breaking.

In the embodiment shown in fig. 3, the main body 2 comprises an insertion opening 25 for the first section 11 to enter the receiving cavity, the first stop portion 26 is arranged axially above the receiving cavity and extends radially, the insertion opening 25 extends through the first stop portion 26, i.e. the insertion opening 25 is located on the first stop portion 26, and the minimum distance from the center to the edge of the insertion opening 25 is smaller than the minimum distance between the center of the receiving cavity and the housing 21, so that the first stop portion 26 is arranged at least partially in a suspended manner above the receiving cavity to stop the second stop portion 236.

In the event that the surface of the heater 22 is not cleaned in time after prolonged use, there may be a greater adhesion between the aerosol-generating article 1 and the heater 22 after heating, such that extraction is difficult when extracting an aerosol-generating article 1 partially inserted into an aerosol-generating device through the second section 12 of the aerosol-generating article 1, and if extraction is forced, problems may occur in which the aerosol-generating article 1 breaks. To solve this problem, in an embodiment, referring to fig. 6, the main body 2 further includes a toggle element 28, the toggle element 28 includes a touch element 281 and an actuator 282, and the actuator 282 is disposed corresponding to the protector 23 to push the protector 23 in the direction of the second position when the touch element 281 is triggered, so as to loosen the connection between the heater 22 and the aerosol-generating article 1. The touch portion 281 may be a control mechanism for generating a control signal, such as a key on the aerosol generating device, an operation command on the touch screen 27, etc., and the actuator portion 282 belongs to an electric mechanism and is electrically connected to the circuit board 242, so that when the circuit board 242 obtains a corresponding control signal, the actuator portion 282 is activated, and the actuator portion 282 responds according to the control signal to push against the protector 23; the touch portion 281 and the actuator portion 282 may belong to a mechanical linkage mechanism, and are connected to each other through a link, a lever, a gear, or the like, so that when the touch portion 281 is triggered, motion and/or force is transmitted through the link, the lever, the gear, or the like, so that the actuator portion 282 pushes up against the supporter 23. Specifically, the aerosol generating device further includes a movable element 5 movably connected to the main body 2, the movable element 5 may include a sliding cover disposed on the periphery of the main body 2 so as to be capable of sliding along the axial direction of the main body 2, or sliding along the lateral direction or the circumferential direction of the main body 2, and the touch portion 281 is disposed on the movement track of the movable element 5, and when the movable element 5 slides along the movement track to the third position, the movable element 5 may push or press or block light to trigger the touch portion 281.

In order to prevent the user from accidentally touching a button or a touch screen 27 or the like provided on the aerosol-generating device when the movable element 5 is moved relative to the main body 2, in the embodiment shown in fig. 6, the touch screen 27 and/or the button may be provided on the movement track of the movable element 5, and when the movable element 5 slides along the movement track to the fourth position, at least part of the movable element 5 blocks the switch and/or the touch screen 27. Preferably, after the moving element 5 reaches the fourth position, it will reach the third position when it continues to travel along its motion trajectory in its travel direction, so that the trigger 281 is triggered. It is not excluded that in other embodiments, after the trigger 281 is triggered, the heater 11 moves backward under the action of the motor, thereby loosening the adhesion between the first segment 11 and the heater.

Of course, in other embodiments, the toggle member 28 may be omitted, but in order to prevent the user from accidentally triggering or activating the gas mist generating device when the user does not temporarily need to use the button or touch panel 27 provided on the gas mist generating device, a movable element may be provided on the main body 2, and the movable element 5 may be slid to the fourth position on the main body 2 to block a mechanism such as the button or touch panel 27 that can trigger or activate the gas mist generating device.

In a more specific embodiment, the movable member 5 includes a cylindrical structure at least partially disposed on the periphery of the housing 21, slidably connected to the periphery of the housing 21, and capable of sliding up and down relative to the housing 21 along the axial direction, the third position and/or the fourth position is disposed on the axial direction of the main body 2, when the cylindrical structure is at the third position or the fourth position, the outer side wall of the housing 21 is at least partially exposed, and in the normal state, the outer side wall of the housing 21 is hidden due to being shielded by the cylindrical structure. Optionally, the path of movement of the tubular structure to trigger the touch portion 281 or the path to occlude the key or touch screen 27 is in the opposite direction to the path of movement of the brace 23 from the first position to the second position, preferably, the tubular structure remains occluding the key or touch screen 27 when the tubular structure is in the third position.

An embodiment of the present application also provides a method of extracting an aerosol-generating article from an aerosol-generating device, the method comprising:

(1) Inserting the aerosol-generating article 1 with the first section 11 of the aerosol-generating article 1 in close fitting connection with the suit 23, preferably with the sleeve 231 of the suit 23 being disposed around the aerosol-forming substrate section 111 in the first section 11 to protect and support the side walls of the aerosol-forming substrate section 111, the close fitting 234 on the sleeve 231 being in close fitting connection with the first cooling section 112 on the first section 11 that is not baked at high temperatures by the heater 22, the interaction force between the sleeve 231 and the first section 11 being borne primarily by the first cooling section 112, the heater 22 needing to be inserted into the interior of the first section 11 in order to heat the aerosol-forming substrate section 111;

(2) Grasping the second section 12 of the aerosol-generating article 1 exposed outside the aerosol-generating device, the manner of grasping the second section 12 being simple and capable of being grasped directly by a finger; then applying an extraction force to the second section 12 that extracts the aerosol-generating article 1 from the aerosol-generating device, moving the suit 23 and the first section 11 in the extraction direction from the first position to the second position, the suit 23 and the aerosol-generating article 1 being able to maintain the same speed, synchronized movement during the movement from the first position to the second position;

(3) When the supporter 23 moves to the stroke end and stops continuing to travel in the extraction direction, the extraction force is continuously applied to the second segment 12 to separate the first segment 11 from the supporter 23 until the supporter 23 is pulled out of the first segment 11, thereby completing extraction of the aerosol-generating article 1 from the aerosol-generating device.

In the aerosol-generating device and the method of extraction described above, the protector provides a kinematic connection between the first section and the housing forming the receiving cavity such that, during extraction, the aerosol-generating article can move relative to the housing via the protector, such that, when the adhesion between the aerosol-generating article and the heater is loosened, the protector can support and protect the aerosol-generating article against breaking or crushing in the receiving cavity, facilitating complete withdrawal of the aerosol-generating article from the aerosol-generating device; moreover, the aerosol-generating article can be extracted by directly grabbing the second section of the aerosol-generating article exposed outside the aerosol-generating device, so that the daily use habit and thinking inertia of a user are better met, and the user experience can be improved.

In the conventional aerosol-generating device, an extractor is provided, and when the aerosol-generating article needs to be pulled out from the aerosol-generating device, the extractor needs to be activated (including an electrically activated extractor or a manually and directly gripped extractor) to move the extractor relative to the receiving cavity, and then the aerosol-generating article needs to be gripped to separate the aerosol-generating article from the extractor.
