Abstract
Description
Technical Field
[0001] This application relates to the field of aerosol technology, and particularly to an aerosol generating device.
Background Art
[0002] Traditional tobacco generating substrates (such as cigarettes, cigars, etc.) burn tobacco during use 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 typically 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 produce an aerosol for the user to inhale.
[0003] The above aerosol generating devices usually also have a dust cover, which can be slid by the user between a first position and a second position. When the aerosol generating device is idle, the user can slide the dust cover to the first position to cover 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 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.

[0036] An embodiment of this application provides an aerosol generating device 100, as Figure 1 and Figure 2 shown. The aerosol generating device 100 includes a housing 10. The housing 10 includes a top cover 11, a middle shell 12, and a bottom cover 13. The top cover 11, the middle shell 12, and the bottom cover 13 enclose to form the housing 10. A longitudinally extending tubular body 20 is disposed inside the housing 10. The tubular body 20 defines a longitudinally extending first chamber 21 for receiving an aerosol generating article 200 used in conjunction with the aerosol generating device 100.
[0037] The outer wall of the tubular body 20 is attached with a heating element 30. The aerosol generating device 100 further includes a battery cell 40 and a main board (not shown in the figure). The controller of the aerosol generating device 100 is disposed on the main board. Both the heating element 30 and the battery cell 40 are electrically connected to the main board. Furthermore, the controller can control the battery cell 40 to supply electric energy to the heating element 30. After the heating element 30 is powered on, it generates heat and transfers the heat to the aerosol generating article 200 in the first chamber 21. At least a part of the active substance of the aerosol generating article 200 is volatilized by heat to generate aerosol, and the user can inhale the aerosol by sucking on the aerosol generating article 200.
[0038] The tubular body 20 is made of a highly thermally conductive material to efficiently conduct the heat generated by the heating element 30 to the aerosol generating article 200. The highly thermally conductive material can be a metal or a ceramic material, and the ceramic material can be any one of oxides, nitrides, carbides, borides, etc.
[0039] The heating element 30 can be a resistive heating wire wound around the outer wall of the tubular body 20, or a thick film heating material printed on the outer wall of the tubular body 20.
[0040] And, in some embodiments, as Figure 4 shown, the heating element 30 extends into the first chamber 21, and the end of the heating element 30 extending in the first chamber 21 is configured as a pin shape or a sheet shape, so that when the aerosol generating article 200 is received in the first chamber 21, the heating element 30 can be inserted into the aerosol generating article 200 for heating. 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. The heating element 30 is directly electrically connected to the main board, and then the controller can control the battery cell 40 to supply electrical energy to the heating element 30. After the heating element 30 obtains electrical energy, it can generate heat.
[0041] Or, in some embodiments, when the heating element 30 is inserted into the aerosol generating article 200 for heating, 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 outside of the tubular body 20, and 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 induces eddy currents in the heating element 30. 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 powder, granules, fragments, strips, or flakes of vanilla leaves, tobacco leaves, homogenized tobacco, and expanded tobacco; alternatively, the solid matrix can contain additional tobacco or non-tobacco volatile flavor compounds to be released when the matrix is heated.
[0044] As Figure 5 shown, the aerosol-generating device 100 further includes a rotating member 50 and a shielding member 60. The shielding member 60 is disposed within the housing 10. The rotating shaft 51 of the rotating member 50 is rotatably connected within the housing 10, and a part of the rotating member 50 is exposed outside the housing 10 to form an operation portion for the user to operate. Thus, the user can drive the rotating member 50 to rotate relative to the housing 10 by operating this operation portion.
[0045] The shielding member 60 is disposed within the housing 10. The shielding member 60 is used to shield or expose the first chamber 21. The rotating member 50 and the shielding member 60 are linked. When the rotating member 50 rotates, the rotating member 50 drives the shielding member 60 to move to shield or expose the first chamber 21.
[0046] Specifically, when the aerosol-generating device 100 is in an idle state, the user operates the rotating member 50 to rotate in a first direction, so that the rotating member 50 drives the shielding member 60 to move towards the first chamber 21 to shield the first chamber 21, as Figure 3 shown. When the user needs to use the aerosol-generating device 100, the user can operate the rotating member 50 to rotate in a second direction opposite to the first direction, so that the rotating member 50 drives the shielding member 60 to move away from the first chamber 21 to expose the first chamber 21. The user can then insert the aerosol-generating article 200 into the first chamber 21, as Figure 7 shown.
[0047] By means of this embodiment, the user can drive the shielding member 60 disposed within the housing 10 to move by operating the rotating member 50 to rotate, thereby exposing or shielding the first chamber 21, and thus providing a brand-new dust-proof design, making the aerosol-generating device 100 more innovative and novel.
[0048] In some embodiments, the rotating member 50 can also be electric and is rotated by electric drive.
[0049] In some embodiments, as Figure 6As shown, the shielding member 60 is provided with a slot 61, and the rotating member 50 is provided with a pushing portion 521 inserted into the slot 61. Thus, when the rotating member 50 rotates, the pushing portion 521 rotates synchronously. During the rotation process, the pushing portion 521 abuts against the inner wall of the slot 61, and further pushes the shielding member 60 to move linearly to expose or shield the first chamber 21.
[0050] In some embodiments, to simplify the structural design, when the rotating member 50 rotates, it drives the shielding member 60 to move linearly.
[0051] Specifically, in one embodiment, as Figure 3 and Figure 5 shown, the aerosol generating device 100 further includes a longitudinally extending bracket 70. An installation groove 72 is provided on the bracket 70, and the battery cell 40 is installed in the installation groove 72, so that the bracket 70 holds the battery cell 40. The bracket 70 provides support for the top cover 11, and a radially extending second chamber 71 is defined between the bracket 70 and the top cover 11. The shielding member 60 is received in the second chamber 71. The second chamber 71 communicates with the first chamber 21. A part of the rotating member 50 is located in the second chamber 71 to be connected to the shielding member 60. Thus, when the rotating member 50 rotates, the rotating member 50 drives the shielding member 60 to perform a reciprocating linear motion along the extension direction of the second chamber 71 to shield or expose the first chamber 21.
[0052] Further, in some embodiments, as Figure 3 shown, a part of the rotating member 50 is received in the second chamber 71 for connection with the shielding member 60, and the other part protrudes from the top cover 11 to form an operation portion, so that it is convenient for the user to operate the rotating member 50 to rotate.
[0053] Moreover, in some embodiments, as Figure 3 shown, the shielding member 60 is provided with a first groove (not shown in the figure). A first magnetic member 80 is installed in the first groove. The bracket 70 is provided with a second groove, and a second magnetic member 90 is installed in the second groove. The first magnetic member 80 and the second magnetic member 90 are magnetically attracted to each other, so that the first magnetic member 80 and the second magnetic member 90 provide magnetic attraction assistance during the movement of the shielding member 60.
[0054] In some embodiments, as Figure 8 shown, the aerosol generating device 100 further includes a key switch 110. The operation portion of the rotating member 50 exposed to the housing 10 can also be used to receive an external pressing force, so that the rotating member 50 moves towards the key switch 110 under the action of the external pressing force to trigger the key switch 110. By means of this embodiment, the user can not only open or close the first chamber 21 by operating the rotating member 50, but also trigger the key switch to generate a trigger signal, so that the aerosol generating device 100 realizes a predetermined function, making the function of the rotating member 50 diversified.
[0055] In some embodiments, the button switch 110 may be a start switch. When the user needs to use the aerosol generating device 100, the user may first operate the rotating member 50 to rotate so as to expose the first chamber 21. Then, the user inserts the aerosol generating article 200 into the first chamber 21. After inserting the aerosol generating article 200, the user then presses the rotating member 50 so that the rotating member 50 triggers the button switch 110. The button switch 110 is electrically connected to the controller. After the button switch 110 is triggered, a trigger signal is generated. The controller can obtain this trigger signal and control the battery cell 40 to supply electrical energy to the heating element 30 according to this trigger signal, so that the heating element 30 starts to heat up.
[0056] Alternatively, in some embodiments, the aerosol generating device 100 has an automatic start heating function. When the aerosol generating device 100 detects that the aerosol generating article 200 is inserted into the first chamber 21, the controller controls the heating element 30 to start heating. At this time, the button switch 110 can control to implement other functions. For example, when the user finishes sucking, the aerosol generating device 100 can be controlled to turn off and cut off the power supply.
[0057] In some embodiments, as Figure 8 shown, a trigger member 120 is supported on the button switch 110. A shaft hole (not shown in the figure) is provided on the trigger member 120, and the rotating shaft 51 is inserted into this shaft hole. When the rotating member 50 is pressed, the rotating member 50 moves downward, and further causes the rotating member 50 to drive the rotating shaft 51 to move downward synchronously. The rotating shaft 51 can then apply an extrusion force to the trigger member 110, and the trigger member 110 squeezes the button switch 110 under the action of the extrusion force, so that the button switch is triggered to generate a trigger signal.
[0058] In some embodiments, the button switch 110 can also be provided under the rotating member 50, and then the rotating member 50 squeezes the button switch 110 so that the button switch 110 is triggered.
[0059] Further, in some embodiments, as Figure 8 and Figure 9 shown, an inlet 111 for inserting the aerosol generating article into the first chamber 21 and a through hole 112 through which a part of the rotating member 50 is exposed for the user to operate are provided on the top cover 11. The hole wall 1121 of the through hole 112 has a certain extension length. Then, when the rotating member 50 is pressed and moves downward, the hole wall 1121 has a limiting effect on the rotating member 50, preventing the rotating member 50 from deviating when moving downward, and further affecting the triggering of the button switch 110.
[0060] Also, in some embodiments, a notch 11211 is provided at the bottom of the hole wall 1121. The rotating shaft 51 passes through the notch 11211. By providing the notch 11211, it is possible to prevent the hole wall 1121 from blocking the rotating member 50 when the rotating member 50 moves downward under the pressing force, thereby affecting the triggering of the key switch 110.
[0061] 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 cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present application.
