Technical Field

[0001] This application relates to the technical field of aerosols, and in particular to an extractor and an aerosol generating device having the extractor.

Background Art

[0002] In the use of traditional tobacco generating substrates (such as cigarettes, cigars, etc.), tobacco is burned to produce tobacco smoke. There are already products in the prior art that release compounds without burning by heating to replace these traditional tobacco generating substrates. Examples of such products are aerosol generating devices, which generally include a heating element and a receiving chamber for receiving an aerosol generating article used in conjunction with the aerosol generating device. When the aerosol generating article is received in the receiving chamber, the heating element heats the aerosol generating article to generate an aerosol for the user to inhale.

[0003] The above aerosol generating devices generally also have a dust-proof cover that can be slid left and right between a first position and a second position by the user. When the aerosol generating device is idle, the user can slide the dust-proof cover to the first position to block the receiving chamber and prevent dust in the air from falling into the receiving chamber. When the aerosol generating device needs to be used, the dust-proof cover can be slid to the second position to expose the receiving chamber, and the user can then insert the aerosol generating article into the receiving chamber.

[0037] An embodiment of the present application provides an aerosol generating device 100, as Figures 1-3 shown, the aerosol generating device 100 includes a main body 10 and an extractor 20. The main body 10 is provided with a receiving chamber 11, and the extractor 20 is removably received in the receiving chamber 11.

[0038] The extractor 20 includes a housing 21 which defines a chamber 211 formed therein. An opening 212 communicating with the chamber 211 is provided at the bottom of the housing 21. The chamber 211 is used to accommodate the aerosol-generating article 200 which is used in conjunction with the aerosol-generating device 100. The main body 10 further includes an elongated heating element 30. At least a part of the heating element 30 extends through the opening 212 into the chamber 211, and the end of the heating element 30 extending in the chamber 211 is configured in a pin shape or a sheet shape. Thus, when the aerosol-generating article 200 is accommodated in the chamber 211, the heating element 30 can be inserted into the aerosol-generating article 200 for heating, and part of the active substances in the aerosol-generating article 200 can be volatilized by heating to generate an aerosol.

[0039] The aerosol-generating device 100 further includes a main board 50 and a battery cell 40. A controller of the aerosol-generating device 100 is provided on the main board 50. Both the heating element 30 and the battery cell 40 are electrically connected to the controller. Further, the controller can control the battery cell 40 to supply electrical energy to the heating element 30, so that the heating element 30 heats the aerosol-generating article 200.

[0040] In some embodiments, the heating element 30 can be a ceramic heating element. The ceramic heating element is a heating element made by sintering an electrothermal body and ceramics together at a high temperature and fixing them together. After the heating element 30 is powered on, it can be heated.

[0041] Alternatively, in some embodiments, the heating element 30 can also heat the aerosol-generating article 200 by electromagnetic induction. Specifically, an induction coil (not shown in the figure) can be wound around the heating element 30. The controller controls the battery cell 40 to pass an alternating current into the induction coil. The induction coil generates a changing magnetic field under the action of the alternating current. The changing magnetic field penetrates the heating element 30, and then the heating element 30 induces eddy currents. The heating element 30 generates heat under the action of the eddy current effect and the hysteresis effect, and then can heat the aerosol-generating article 200.

[0042] To enable the heating element 30 to induce eddy currents, a suitable material for the heating element 30 can be any one of graphite, molybdenum, silicon carbide, stainless steel, niobium, aluminum, nickel, iron, copper, nickel-containing compounds, titanium, and metal material composites. In some embodiments, to better induce eddy currents to improve the heating efficiency, the material of the heating element 30 is preferably a ferromagnetic material or composed of a ferromagnetic material. Ferromagnetic materials such as ferrite iron, ferromagnetic alloys (such as ferromagnetic steel or stainless steel), ferromagnetic particles, and ferrites.

[0043] The aerosol-generating article 200 preferably uses a tobacco-containing material that releases volatile compounds from the article when heated; alternatively, it can also be a non-tobacco material that is suitable for electrically heated smoking after heating. The aerosol-generating article 200 preferably uses a solid matrix, which can include one or more of powders, granules, fragments, strips, bands or flakes of vanilla leaves, tobacco leaves, homogenized tobacco, expanded tobacco, etc.; alternatively, the solid matrix can contain additional tobacco or non-tobacco volatile flavor compounds to be released when the matrix is heated.

[0044] The aerosol-generating device 100 further includes an air passage 60 that communicates the chamber 211 with the outside air. When the user sucks on the aerosol-generating article 200, the outside air enters the chamber 211 through the air passage 60, and further enters the aerosol-generating article 200, and then carries the aerosol in the aerosol-generating article 200 and escapes along the air flow passage inside the aerosol-generating article 200 for the user to inhale.

[0045] After the heating element 30 finishes heating, the user operates the extractor 20 to remove the extractor 20 from the receiving bin 11 in the main body 10. The extractor 20 carries the aerosol-generating article 200 and separates from the main body 10 together, so that the aerosol-generating article 200 is separated from the heating element 30. By using the extractor 200 to extract the aerosol-generating article 200, it can slow down the adhesion of the solid matrix in the aerosol-generating article 200 to the heating element 30 due to high temperature. The adhesion of the heated solid matrix to the heating element 30 will, on the one hand, cause frequent cleaning of the heating element 30, and on the other hand, also reduce the heating efficiency of the heating element 30.

[0046] As Figure 2 shown, the housing 21 of the extractor 20 is also defined with a receiving bin 213 formed therein. The receiving bin 213 communicates with the chamber 211. The extractor 20 further includes a rotating member 22. The rotating member 22 extends in the longitudinal direction and is received in the receiving bin 213. Opposite side walls of the receiving bin 213 are provided with shaft holes 2131. The rotating shaft 228 of the rotating member 22 is rotatably connected to the shaft holes 2131, so that the rotating member 22 can rotate between a first position and a second position in the longitudinal plane, thereby reducing the structural space occupied when the rotating member 22 rotates. The rotating member 22 can be directly manually operated by the user to rotate.

[0047] The rotating member 22 is provided with a first through hole 221 for the aerosol-generating article 200 to pass through. When the user operates the rotating member 22 to rotate from the first position to the second position, the first through hole 221 is offset from the chamber 211. At this time, the chamber 211 is blocked by the rotating member 22, and the aerosol-generating article 200 cannot be inserted into the chamber 211 through the first through hole 221. As Figure 4As shown, when the user does not need to use the aerosol generating device, the rotating member 22 can be rotated to the second position to prevent dust in the air from falling into the aerosol generating device 100.

[0048] When the user needs to use the aerosol generating device 100, the user can operate the rotating member 22 to rotate from the second position to the first position. At this time, the first through hole 221 of the rotating member 22 is linearly communicated with the chamber 211, and the aerosol generating article 200 can pass through the first through hole 221 and be inserted into the chamber 211, as Figure 1 shown.

[0049] In some embodiments, the extractor 20 further includes an elastic member for holding the rotating member 22 in the first position or the second position.

[0050] As a specific embodiment, as Figure 5 and Figure 6 shown, the elastic member is a torsion spring 23. A protrusion 214 is provided on the surface of the housing 21 of the extractor 20. The protrusion 214 includes a blocking portion 2141 and a connecting shaft 2142 connecting the blocking portion 2141 and the surface of the housing 21. The first end 231 of the torsion spring 23 is sleeved on the connecting shaft 2142, so that the first end 231 can rotate around the connecting shaft 2142. The blocking portion 2141 is used to block the first end 231 to prevent the first end 231 from disengaging from the connecting shaft 2142 during rotation.

[0051] The rotating member 22 is provided with a threaded hole 222. A screw 223 is disposed in the threaded hole 222. The screw 223 includes a head 2231 and a rod portion 2232. A part of the rod portion 2232 is screwed into the threaded hole, and the other part extends out of the threaded hole 222. The second end 232 of the torsion spring 23 is sleeved on the rod portion 2232 between the head 2231 of the screw 223 and the threaded hole 222, so that the second end 232 of the torsion spring 23 can rotate around the rod portion 2232. The head 2231 of the screw 223 can block the second end 232 of the torsion spring 23 to prevent the second end 232 of the torsion spring 23 from disengaging during rotation.

[0052] As another specific embodiment, as Figure 7As shown, the first end 231 of the torsion spring 23 is rotatably connected to the protrusion 214. A second through-hole is provided on the rotating member 22, and the second through-hole penetrates through the first surface and the second surface of the rotating member 22 that are oppositely arranged in the thickness direction. The rotating member 22 further includes a fixed shaft 225 passing through the second through-hole. The fixed shaft 225 has a first end 2251 and a second end 2252 along its length direction, and the first end 2251 and the second end 2252 respectively extend out of the second through-hole 224. A blocking portion 22511 is provided at the end of the first end 2251. The second end 232 of the torsion spring 23 is sleeved on the fixed shaft 225 so as to be rotatable around the fixed shaft 225, and the second end 232 of the torsion spring 23 is located between the blocking portion 22511 and the second through-hole, so that the blocking portion 22511 can block the second end 232 of the torsion spring 23 to prevent the second end 232 of the torsion spring 23 from disengaging from the fixed shaft 225 during the rotation process.

[0053] Further, in some embodiments, as Figure 7 shown, the rotating member 22 further includes an axial clip 226, and the axial clip 226 is snap-fitted to the second end 2252 of the fixed shaft 225, thereby holding the fixed shaft 225 in the second through-hole. Specifically, the second end 2252 may be provided with a groove (not shown in the figure), and the axial clip 226 is snap-fitted in the groove.

[0054] In some embodiments, as Figure 6 shown, a notch 2132 is formed in the wall of the receiving chamber 213, and the second end 232 of the torsion spring 23 passes through the notch 2132 and is rotatably connected to the rotating member 22.

[0055] It should be noted that the present application does not limit the setting of the elastic member, and the elastic member may also adopt other structural forms, as long as the elastic member can hold the rotating member 22 in the first position or the second position.

[0056] In some embodiments, as Figure 6 、 Figure 8 and Figure 9 shown, a convex rib 2133 is provided on the inner wall of the receiving chamber 213, and a groove 227 is formed on the surface of the rotating member 22. The groove 227 has a first inner wall 2271 and a second inner wall 2272, and the convex rib 2133 is located between the first inner wall 2271 and the second inner wall 2272. Thus, when the rotating member 22 rotates to the first position, the convex rib 2133 can abut against the first inner wall 2271 to limit the rotating member 22, so that the first through-hole 221 and the chamber 211 are communicated. When the rotating member 22 rotates to the second position, the convex rib 2133 can abut against the second inner wall 2272 to limit the rotating member 22 in the second position.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; under the idea of the present application, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above. For the sake of brevity, they are not provided in detail; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
