[0043] An embodiment of the present application provides an aerosol generating device 100 for an aerosol generating article to generate an aerosol, such as Figure 1 As shown, the aerosol generating device 100 includes a housing 10 having a first end 11 and a second end 12 oppositely arranged along the length direction thereof. The first end 11 is provided with a mouthpiece 111 defining an air outlet hole 1111 for the aerosol to escape from the aerosol generating device 100, so that the user can smoke the aerosol by sucking at the mouthpiece 111.

[0044] In some embodiments, the mouthpiece 111 can also be integrally formed with the housing 10.

[0045] As shown in FIG. 1, the aerosol-generating device 100 further includes a movable assembly 20 disposed in the housing 10. The movable assembly 20 includes a receiving portion 21 having a side wall 211 and a bottom wall 212 that enclose a receiving cavity 213 for receiving the aerosol-generating article 200. The side wall 211 is provided with an opening 214 for the aerosol-generating article 200 to enter or exit the receiving cavity 213. Figures 2-6

[0046] The aerosol-generating device 100 further includes a heating chamber 30 for heating the aerosol-generating article 200 to generate an aerosol, and a heating element 40 extending longitudinally at least partially in the heating chamber 30. The movable assembly 20 is configured to move along the length direction of the aerosol-generating device 100 between a first position and a second position, i.e., the X direction of the coordinate axis. The bottom wall 212 is provided with a through hole 2121 for the heating element 40 to pass through. When the movable assembly 20 moves to the first position, the receiving portion 21 of the movable assembly 20 enters and remains in the heating chamber 30, and at this time, the opening 214 is also located in the heating chamber 30 and is blocked from being exposed. At the same time, the heating element 40 passes through the through hole 2121 and enters the receiving cavity 213 to be inserted into the aerosol-generating article 200 for heating. As shown in FIG. 2, the aerosol-generating article 200 is heated to volatilize and generate an aerosol, and the aerosol is released in the receiving cavity 213. When a user sucks at 212, the aerosol can enter the air outlet hole 1111 of the mouthpiece 111. Figure 1 Figure 2 When the movable assembly 20 moves from the first position to the second position, the receiving portion 21 is separated from the heating chamber 30, and the heating element 40 stops heating the aerosol-generating article 200. At this time, the opening 214 is exposed, as shown in FIG. 3. The user can directly take out the aerosol-generating article 200 from the receiving cavity 213, or place the aerosol-generating device 100 horizontally with the opening 214 facing downward, and the aerosol-generating article 200 can directly fall out of the receiving cavity 213, which is convenient for the user to replace the aerosol-generating article 200 and is simple to operate.

[0047] Figure 5 Figure 6

[0048] ​​​​​In some embodiments, the heating element 40 can be a ceramic heating element, which is a heating element made by sintering an electrothermal body and a ceramic together. The heating element 40 is directly electrically connected to the controller on the main plate 50, so that the controller can control the power supply of the battery 60 to the heating element 40. After the heating element 40 obtains the power, it can generate heat.

[0049] Alternatively, in some embodiments, the heating element 40 generates heat through electromagnetic induction. Specifically, an induction coil (not shown) can be wound around the periphery of the heating chamber 30. The controller controls the battery 60 to pass an alternating current into the induction coil. The induction coil generates a changing magnetic field under the action of the alternating current, which penetrates the heating element 40 and induces eddy currents in the heating element 40. The heating element 40 generates heat under the action of the eddy current effect and the magnetic hysteresis effect, thereby heating the aerosol generating article 200.

[0050] In order for the heating element 40 to induce eddy currents, the material of the heating element 40 can be any one of graphite, molybdenum, silicon carbide, stainless steel, niobium, aluminum, nickel, iron, copper, a nickel-containing compound, titanium, and a metal material composite. In some embodiments, in order to better induce eddy currents and improve heating efficiency, the material of the heating element 40 is preferably a ferromagnetic material or is composed of a ferromagnetic material, such as ferritic iron, ferromagnetic alloy (such as ferromagnetic steel or stainless steel), ferromagnetic particles, and ferrite.

[0051] Alternatively, in some embodiments, the heating element is provided on the outer wall of the heating chamber 30, such as a mesh-shaped electric resistance heating element, a heating film, or a heating material printed on the outer wall of the heating chamber 30 by thick film printing. When the movable assembly 20 moves to the first position, the inner wall of the heating chamber 30 contacts the accommodation portion 21. The heating element transmits heat to the accommodation portion 21 through the inner wall of the heating chamber 30, and then the accommodation portion 21 transmits the heat to the aerosol generating article 200 in the circumferential direction. This method is referred to as a circumferential heating method, and the heating method of inserting the heating element into the aerosol generating article 200 in the above embodiments is referred to as a central heating method.

[0052] In some embodiments, the housing 10 includes a first housing 110 and a second housing 120. When the movable assembly 20 moves to the first position, the first housing 110 and the second housing 120 abut each other to form a complete housing 10, as shown in FIG. 2A. When the movable assembly 20 moves to the second position, the first housing 110 and the second housing 120 are separated from each other to expose the opening 214, as shown in FIG. 2B. Figure 1 Figure 6

[0053] ​​Specifically, the first housing 110 and the movable assembly 20 are fixedly connected, and the first housing 100 is configured to be operable to move relative to the second housing 120 along the length direction of the aerosol generating device 100. When the user replaces the aerosol generating article 200, the user can operate the first housing 110 to move away from the second housing 120, so that the first housing 110 and the second housing 120 are separated from each other, and at the same time, the first housing 110 drives the movable assembly 20 to move to the second position, so that the opening 214 is exposed to replace the aerosol generating article 200. After replacement, the user can operate the first housing 110 to move towards the second housing 120, so that the first housing 110 and the second housing 120 are attached to each other, and at the same time, the first housing 110 drives the movable assembly 20 to move from the second position to the first position, so that the accommodation portion 21 of the movable assembly 20 enters the heating chamber 30, and the heating chamber 30 heats the aerosol generating article 200.

[0054] In some embodiments, as shown in Figure 7 , the outer surface of the first housing 110 is provided with a plurality of spaced recesses 1101, which form operation portions for user operation, so that the user generates sliding when operating the first housing 110 to move, that is, the plurality of spaced recesses 1101 can play a role of anti-skid. Alternatively, in some embodiments, the operation portion can also be a protrusion provided on the outer surface of the first housing 110. Alternatively, the operation portion can also be a sunken groove capable of allowing the user's fingers to extend into.

[0055] In some embodiments, a gap can also be provided on the housing 10, and the user can operate the movable assembly 20 to move between the first position and the second position. When the user operates the movable assembly 20 to move to the second position, the opening 214 of the accommodation portion 21 is aligned with the gap of the housing 10, and then the user can take out the aerosol generating article 200 from the accommodation cavity 213 to replace the aerosol generating article 200. After replacement, the user continues to operate the movable assembly 20 to move from the second position to the first position, so that the opening 214 is misaligned with the gap of the housing 10, and the opening 214 is avoided from being exposed.

[0056] In some embodiments, as shown in Figure 2 and Figure 8 , the accommodation cavity 213 includes a first portion 2131 and a second portion 2132 distributed longitudinally, the first portion is used to install the mouthpiece 111, and the second portion 2132 accommodates the aerosol generating article 200. The aerosol generated by the aerosol generating article 200 volatilized by heating is released in the second portion 2132, and then directly enters the mouthpiece 111 in the first portion 2131.

[0057] Further in some embodiments, as shown in Figure 2As shown, the outer surface of the suction nozzle 111 is formed with a groove, and a gap 1112 is formed between the inner wall of the accommodation chamber 213 and the groove. The gap 1112 is filled with a sealing member 70, which can be any one of a soft rubber member such as silicone, rubber, or latex, so that the sealing member 70 can be filled in the gap 112 by interference fit to seal the assembly gap between the movable assembly 20 and the suction nozzle 111, thereby preventing the aerosol in the accommodation chamber 213 from leaking through the assembly gap between the movable assembly 20 and the suction nozzle 111.

[0058] Alternatively, in some embodiments, a groove can also be provided on the inner wall of the accommodation chamber 213, and the gap 1112 is defined by the groove and the outer surface of the suction nozzle 111.

[0059] In some embodiments, as shown in Figure 9 and Figure 10 As shown, the movable assembly 20 is also provided with a first magnetic member 22 and a second magnetic member 23 which are spaced apart along the moving direction of the movable assembly 20. The aerosol generating device 100 further includes a third magnetic member 24 which is arranged outside the movable assembly 20 and is used to magnetically attract the first magnetic member 22 or the second magnetic member 23 during the movement of the movable assembly 20.

[0060] Specifically, as shown in Figure 9 When the movable assembly 20 moves to the first position, the third magnetic member 24 and the first magnetic member 22 are arranged opposite to each other and magnetically attract each other, thereby keeping the movable assembly 20 at the first position. When the movable assembly 20 moves from the first position to the second position, the first magnetic member 22 and the third magnetic member 24 gradually move away from each other, while the second magnetic member 23 and the third magnetic member 24 gradually move closer to each other, thereby increasing the magnetic attraction force between the second magnetic member 23 and the third magnetic member 24. Under the action of the magnetic attraction force, the movable assembly 20 can be automatically moved to the second position and kept at the second position, as shown in Figure 10 .

[0061] Similarly, when the movable assembly 20 moves from the second position to the first position, the second magnetic member 23 and the third magnetic member 24 gradually move away from each other, while the first magnetic member 22 and the third magnetic member 24 gradually move closer to each other, thereby increasing the magnetic attraction force between the first magnetic member 22 and the third magnetic member 24. Under the action of the magnetic attraction force, the movable assembly 20 can be automatically moved to the first position and kept at the first position. The first magnetic member 22, the second magnetic member 23, and the third magnetic member 24 cooperatively provide a magnetic attraction assistance force during the movement of the movable assembly 20, so that the movable assembly 20 can be automatically moved to the first position or the second position and kept at the first position or the second position under the action of the magnetic attraction force, thereby improving the operation feeling and use experience of the user.

[0062] Further in some embodiments, as shown in Figure 11 , Figure 1 the magnetic poles of the first magnetic member 22, the second magnetic member 23 and the third magnetic member 24 are configured to be distributed along the thickness direction of the aerosol generating device 100, that is, along the Y direction of the coordinate axis, so that when the movable assembly 20 moves to the first position or the second position, the third magnetic member 24 and the first magnetic member 22 or the second magnetic member 23 can be relatively magnetically attracted, thereby stably holding the movable assembly 20 in the first position or the second position.

[0063] Further in some embodiments, as shown in Figure 2 , Figure 8 , Figure 9 and Figure 12 the aerosol generating device 100 further comprises a support member 80 for supporting the movable assembly 20, the support member 80 having a support surface 811 for supporting the movable assembly 20, and an extension wall 812 extending from the support surface 811 away from the movable assembly 20, the support surface 811 and the extension wall 812 enclosing a receiving chamber 813. The movable assembly 20 further comprises a longitudinal extension 25 for mounting the first magnetic member 22 and the second magnetic member 23, specifically, the longitudinal extension 25 forms a first mounting groove 251 and a second mounting groove 252 arranged at intervals along the longitudinal direction, and the first magnetic member 22 and the second magnetic member 23 are respectively mounted in the first mounting groove 251 and the second mounting groove 252. The support surface 811 is provided with a through hole 8111 communicating with the receiving chamber 813, and a recess 8112 adjacent to the through hole 8111, and the third magnetic member 24 is mounted in the recess 8112. Further, when the movable assembly 20 moves between the first position and the second position, the longitudinal extension 25 can pass through the through hole 8111 to enter or exit the receiving chamber 813, and when the movable assembly 20 moves to the first position or the second position, the third magnetic member 24 prevented in the recess 8112 can be arranged opposite to the first magnetic member 22 or the second magnetic member 23 and magnetically attracted to each other, so as to hold the movable assembly 20 in the first position or the second position.

[0064] An embodiment of the present application further provides an aerosol generating system, as shown in Figure 2 and Figure 6As shown, the aerosol generating system includes the aerosol generating device 100 in the above embodiments and the aerosol generating article 200 used in conjunction with the aerosol generating device 100, and the aerosol generating device 100 is used to accommodate and heat the aerosol generating article 200 to generate aerosol. When the aerosol generating article 200 needs to be replaced, the movable assembly 20 in the aerosol generating device 100 is moved to the second position to expose the opening 214, and the user can take out and replace the aerosol generating article 200 through the opening 214. After the replacement is completed, the movable assembly 20 is moved from the second position to the first position, and at least a part of the aerosol generating article 200 is located in the heating chamber 30 of the aerosol generating device 100, so that the aerosol generating device 100 can be started to heat the aerosol generating article 200.

[0065] In some embodiments, as Figure 6 As shown, the aerosol generating article 200 has a first end 210 and a second end 220 arranged opposite along the moving direction of the movable assembly 20, and a through hole 230 communicating the first end 210 and the second end 220. When the movable assembly 20 moves to the first position, at least a part of the longitudinally extending heating element 40 can be inserted into the through hole 230, thereby heating the aerosol generating article 200. When the movable assembly 20 moves to the second position, the heating element 40 is separated from the through hole 230, and the aerosol generating article 200 is exposed through the opening 214, and the user can take out and replace the aerosol generating article 200.

[0066] The aerosol-forming substrate in the aerosol generating article 200 can be tobacco shreds, tobacco powder or other tobacco extracts, derivatives, tea leaves, mint leaves, agarwood, etc. biological functional substances or other medical drugs or chemicals. Propylene glycol, glycerol, a certain amount of water, nicotine salt, essence and a small amount of adhesive and other materials can be added to the aerosol-forming substrate to form a paste or a gel, which is then molded by a mold or extruded and stretched into a strip, and then cut into blocks or short columns. After biological enzyme treatment and fermentation, the inside becomes a loose high-porosity structure, and then it is dried or air-dried for a certain period of time.

[0067] Further in some embodiments, when the movable assembly 20 moves to the first position, at least a part of the heating element 40 extends into the through hole 230 and maintains a gap with the hole wall of the through hole 230 (not shown in the figure), so as to avoid direct contact between the heating element 40 and the aerosol-forming substrate in the aerosol generating article 200, which may cause the aerosol-forming substrate to be overheated, thereby affecting the smoking taste of the aerosol.
