Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1, 2, 3, 4 and 10, the present application provides an aerosol-generating device 10 comprising a heating means 100 and a power supply means 200. The heating apparatus 100 is provided with a heating chamber 102 and an air inlet 101 and an air outlet 103 in communication with the heating chamber 102, the heating chamber 102 being operable to heat the aerosol-generating substrate 20. The power supply device 200 is detachably connected to an end of the heating device 100 near the air inlet 101, and the power supply device 200 can be used for supplying electric power to the heating device 100. The aerosol-generating substrate 20 may refer to a material that provides a volatile component by heating, among other things. For example, the aerosol-generating substrate 20 may refer to any tobacco-containing material. More specifically, the aerosol-generating substrate 20 may refer to one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes, and the like.

In the aerosol-generating device 10, when the power supply device 200 is insufficient, the user can directly separate the power supply device 200 from the heating device 100, and then connect another power supply device 200 with sufficient power to the heating device 100, thereby ensuring the continuous operation of the heating device 100. In the process, the user does not need to wait and is convenient to operate, and better user experience is achieved. Furthermore, the user may separate the heating means 100 and the power supply means 200 before use of the aerosol-generating device 10 and load the aerosol-generating substrate 20 into the heating chamber 102 directly from the air inlet 101 of the heating means 100. Reconnecting the power supply means 200 to the heating means 100 after the aerosol-generating substrate 20 has entered the heating chamber 102 ensures that the aerosol-generating substrate 20 has entered the heating chamber 102 sufficiently to facilitate improved aerosol generation and efficiency of use of the aerosol-generating substrate 20.

Referring to fig. 4, 5, 6 and 7, an end of the heating device 100 near the air inlet 101 may be referred to as an air inlet end, and the air inlet end is provided with a first connecting component 310. The power supply device 200 is provided with a second connecting component 320, and the power supply device 200 is detachably connected with the first connecting component 310 through the second connecting component 320 so as to be electrically connected with the air inlet of the heating device 100. The connection manner of the first connection assembly 310 and the second connection assembly 320 may include, but is not limited to, one or more of a magnetic attraction connection manner, a snap connection manner, a knob connection manner, a screw connection manner, and other detachable connection manners.

Specifically, in the embodiment shown in fig. 4, 5, 6 and 7, the first connecting assembly 310 includes a base 311 and a first magnetic member 312, the first magnetic member 312 is connected to the base 311, the base 311 is disposed at the air inlet end of the heating apparatus 100, and a through hole communicating with the heating cavity 102, that is, the air inlet 101 of the heating apparatus 100, is opened on the base 311. The second connecting assembly 320 includes an upper cover 321 and a second magnetic member 322, the second magnetic member 322 is connected to the upper cover 321, and the upper cover 321 is disposed on the power supply device 200. The magnetic attraction fit makes the connection and disconnection of the heating device 100 and the power supply device 200 more convenient.

Further, as shown in fig. 5 and 6, in some embodiments, the upper cover 321 is formed with a limit groove 3211, the base 311 is formed with a first limit boss 3111, and the upper cover 321 is in limit fit with the first limit boss 3111 through the limit groove 3211 to be fixed with the base 311. Such a configuration is provided to facilitate improvement in reliability when the power supply device 200 and the heating device 100 are connected.

Further, as shown in fig. 5 and 6, in some embodiments, the second magnetic member 322 is located outside the position-limiting groove 3211 and extends in a ring shape along the circumferential direction of the upper cover 321, and the first magnetic member 312 is in a ring shape along the circumferential direction of the base 311 and corresponds to the second magnetic member 322. Due to the structure, the first magnetic part 312 on the heating device 100 and the second magnetic part 322 on the power supply device 200 can have more angles and larger areas when being matched magnetically, that is, the magnetic attraction force between the heating device 100 and the power supply device 200 is more uniformly distributed and the connection is more reliable. The first magnetic member 312 and the second magnetic member 322 may be magnets. It should be noted that, when the first magnetic element 312 and the second magnetic element 322 are attracted and mated, one end of the first magnetic element 312 close to the second magnetic element 322 and one end of the second magnetic element 322 close to the first magnetic element 312 are opposite magnetic poles, or the first magnetic element 312 and the second magnetic element 322 are integrally like magnets.

Further, as shown in fig. 5, 6 and 7, in some embodiments, the base 311 is further provided with a first electrode 313 and a first electrode hole 3112, the first electrode hole 3112 is disposed on the top surface of the first limiting boss 3111, and the first electrode 313 penetrates through the base 311 through the first electrode hole 3112. The upper cover 321 is further provided with a second electrode 323 and a second electrode hole 3212, the second electrode hole 3212 is opened at the bottom of the limiting groove 3211, and the second electrode 323 penetrates through the base 311 through the second electrode hole 3212. When the power supply device 200 is connected to the air inlet of the heating device 100, the heating device 100 is electrically connected to the power supply device 200 by the first electrode 313 on the base 311 contacting the second electrode 323 of the top cover 321.

Further, in the embodiment shown in fig. 4 and 6, the outer contour shape of the cross section of the first limit projection 3111 of the base 311 on the heating device 100 is an arc shape, and the arc shape thereof is a preferred arc. Accordingly, the limit groove 3211 of the upper cover 321 on the power supply device 200 is matched with the first limit boss 3111 in shape and size. The arrangement of the structure can ensure that the first electrode 313 and the second electrode 323 just face and contact each other when the first limit boss 3111 on the heating device 100 is connected and matched with the limit groove 3211 on the power supply device 200, thereby ensuring that the heating device 100 and the power supply device 200 can be electrically connected.

In other embodiments, the outer contour of the cross section of the first stopper protrusion 3111 may also be in the shape of a sector, a semicircle, or the like. In other words, the outer contour shape of the cross section of the first limiting protrusion 3111 can be various, and it is intended that the first limiting protrusion 3111 can play a positioning role when being connected and matched with the limiting groove 3211, so as to ensure that the first electrode 313 and the second electrode 323 can be electrically connected.

Referring to fig. 3, 6, 7, 8, 9 and 10, in some embodiments, the power supply device 200 is provided with a vent 201, and when the power supply device 200 is fixed to the air inlet end of the heating device 100, the vent 201 is communicated with the air inlet 101. As shown in fig. 10, such a configuration is advantageous for external air to smoothly enter the heating cavity 102 of the heating apparatus 100 through the vent holes 201 of the power supply apparatus 200, and at the same time, part of heat generated during the operation of the power supply apparatus 200 is taken away by the air in the vent holes 201, which is advantageous for reducing the temperature of the power supply apparatus 200, and also for allowing condensate generated when the aerosol-generating substrate 20 in the heating cavity 102 is baked to flow down along the hole walls of the vent holes 201, thereby preventing other structures of the power supply apparatus 200 from being corroded.

Specifically, in the embodiment as shown in fig. 7, the power supply device 200 includes a power supply body 210 and a heat conductive pipe 220. The power supply main body 210 is formed with a through air hole 201, the heat pipe 220 is inserted into the power supply main body 210 through the air hole 201, the heat conductivity coefficient of the heat pipe 220 is greater than that of the power supply main body 210, and the heat pipe 220 is used for communicating with the heating cavity 102 of the heating device 100. The heat pipe 220 may be a metal pipe having high thermal conductivity, such as a copper pipe or an alloy pipe. Such an arrangement can ensure that heat generated by the entire power supply device 200 is intensively conducted to the heat conductive pipe 220, so that the heat is taken away by the gas passing through the heat conductive pipe 220 to lower the temperature of the power supply body 210.

Further, with reference to fig. 7, in an embodiment, the power supply main body 210 includes a housing 211 and a battery 212 disposed in the housing 211. The heat conducting pipe 220 penetrates through the middle of the housing 211 along the axial direction of the housing 211, and the heat conducting pipe 220 and the outer wall of the housing 211 enclose a battery compartment for accommodating the battery 212.

In other embodiments, the battery compartment for accommodating the battery 212 in the housing 211 may be formed only by the structure of the housing 211 itself.

Referring to figures 8 and 9, in some embodiments, at least one cross-section of the vent 201 of the power supply means 200 has a diameter less than the diameter of the cross-section of the aerosol-generating substrate 20, and the walls of the vent 201 are adapted to abut the aerosol-generating substrate 20 to urge the aerosol-generating substrate 20 into the heating chamber 102 of the heating device 100. When the user detaches the power supply means 200 from the heating apparatus 100 and installs the aerosol-generating substrate 20 into the heating chamber 102 of the heating apparatus 100 via the air inlet 101, the power supply means 200 may be connected to the air inlet of the heating apparatus 100 again, and in this process, the wall of the vent 201 of the power supply means 200 may abut against the portion of the aerosol-generating substrate 20 exposed outside the heating chamber 102 to push the aerosol-generating substrate 20 into the heating chamber 102, thereby ensuring that the aerosol-generating substrate 20 may enter the heating chamber 102 of the heating apparatus 100 sufficiently and preventing the aerosol-generating substrate 20 from escaping from the heating chamber 102 during use.

For example, in the embodiment shown in fig. 8, the vent 201 of the power supply 200 is a tapered hole, the vent 201 has a first end 2011 and a second end 2012, the first end 2011 of the vent 201 is proximate to the side of the power supply 200 for connection to the heating device 100, and the aperture of the first end 2011 is greater than or equal to the diameter of the cross-section of the aerosol-generating substrate 20 and the aperture of the second end 2012 of the vent 201 is less than the diameter of the cross-section of the aerosol-generating substrate 20. In other words, the vent hole 201 is shaped such that one end is larger and the other end is smaller, and the larger diameter end of the vent hole 201 is located close to the second connection assembly 320 on the power supply device 200. Taking the example where the aerosol-generating substrate 20 is a cigarette having a smoking section and a filtering section, when the length of the cigarette is greater than the length of the heating cavity 102 of the heating device 100, after the user loads the smoking end of the aerosol-generating substrate 20 into the heating cavity 102 along the air inlet end of the heating device 100, at least part of the filtering end of the aerosol-generating substrate 20 is still located outside the heating cavity 102, at this time, the user can directly connect the power supply device 200 to the air inlet end of the heating device 100, and during the connection process, the wall of the tapered vent hole 201 can abut against the filtering end of the aerosol-generating substrate 20 to further push the aerosol-generating substrate 20 into the heating cavity 102. In other words, the electrical connection of the power supply means 200 and the heating means 100, and the loading of the aerosol-generating substrate 20 into position within the heating chamber 102, may be completed simultaneously by only one operation, which is more convenient and faster to operate and is beneficial to enhancing the user experience.

As another example, in the embodiment shown in fig. 9, the vent hole 201 of the power supply device 200 has two stages distributed in a stepped manner. Taking the case that the vent 201 has two sections distributed in a stepped manner as an example, the vent 201 includes a first hole section 2011 and a second hole section 2012 sequentially arranged along the axial direction of the power supply device 200, and the first hole section 2011 is disposed near one end of the power supply device 200 for connecting with the heating device 100. The first bore section 2011 and the second bore section 2012 are both cylindrical bores, and the bore diameter of the first bore section 2011 is larger than the bore diameter of the second bore section 2012, the bore diameter of the first bore section 2011 is larger than or equal to the cross-sectional diameter of the filter section of the aerosol-generating substrate 20, and the bore diameter of the second bore section 2012 is smaller than the filter section of the aerosol-generating substrate 20. When the user has loaded the aerosol-generating substrate 20 into the heating chamber 102 of the heating apparatus 100 and then connected the first bore section 2011 of the power supply 200 to the air inlet end of the heating apparatus 100, the filter section of the aerosol-generating substrate 20 exposed outside the heating chamber 102 may extend into the first bore section 2011 of the power supply 200. As the pore size of the second pore section 2012 is smaller than the cross-sectional diameter of the filtering end of the aerosol-generating substrate 20, the pore walls where the first pore section 2011 transitions to the second pore section 2012 can abut against the filtering end of the aerosol-generating substrate 20 to push the aerosol-generating substrate 20 into the heating chamber 102.

It is noted that the length H of the first bore section 2011, i.e. the distance between the bore wall of the filter section for holding the aerosol-generating substrate 20 and the upper surface of the power supply 200, is arranged to be sufficient to hold the filter section of the aerosol-generating substrate 20 such that the smoking section of the aerosol-generating substrate 20 fully enters the heating cavity 102 of the heating apparatus 100. In some more specific embodiments thereof, the length H of the first bore section 2011 may be 3mm to 26 mm.

In other embodiments, the number of the stages of the ventilation holes 201 of the power supply device 200 distributed in a stepped manner may be three or more, which aims to ensure that when the power supply device 200 is connected to the air inlet end of the heating device 100, at least a part of the aerosol-generating substrate 20 may extend into the ventilation holes 201 and further enter the heating cavity 102 of the heating device 100 under the support of the walls of the ventilation holes 201.

Referring to fig. 1, 2, 10 and 11, in some embodiments, an end of the heating device 100 near the air outlet 103 is an air outlet end, the air outlet end is provided with a third connecting assembly 330, and the power supply device 200 is detachably connected to the third connecting assembly 330 through the second connecting assembly 320 to be fixed to the air inlet end of the heating device 100. When the user stops using the aerosol-generating device 10, the power supply device 200 may be separated from the heating device 100, and the power supply device 200 may be connected to the third connecting assembly 330 through the second connecting assembly 320 to be fixed to the air inlet end of the heating device 100. In other words, when the power supply device 200 does not need to supply power to the heating device 100, the power supply device 200 may be fixed to the air outlet end of the heating device 100, so as to ensure the integrity of the aerosol-generating apparatus 10, avoid the power supply device 200 from being lost, and facilitate a user to find the power supply device 200 to start the heating device 100 in time when the user returns to use the aerosol-generating apparatus 10.

Specifically, in the embodiment shown in fig. 2 and 11, the third connecting assembly 330 includes a top seat 331 disposed at the air outlet end of the heating apparatus 100 and a suction nozzle 332, and the suction nozzle 332 is disposed through the top seat 331 and communicates with the heating cavity 102. The top seat 331 is provided with a second limit boss 3311 for limiting and matching with the limit groove 3211 of the upper cover 321 of the power supply device 200. The power supply device 200 is provided with a vent hole 201, when the power supply device 200 is connected with the air outlet end of the heating device 100, the suction nozzle 332 is at least partially accommodated in the vent hole 201, that is, the power supply device 200 can be sleeved on the suction nozzle 332 of the heating device 100 through the vent hole 201, and by the structure, the suction nozzle 332 can be used for limiting the power supply device 200 to a certain extent so as to improve the connection reliability, and the suction nozzle 332 can be protected by the power supply device 200.

Referring to fig. 13, the present application further relates to a method of using an aerosol-generating device 10, which is based on the aerosol-generating device 10 according to any of the above embodiments, the method comprising the steps of:

step S100, separating the power supply device 200 from the heating device 100;

a step S200 of loading aerosol generating substrate 20 from said air inlet 101 into the heating chamber 102 of said heating apparatus 100;

a step S300 of connecting the heating device 100 to the power supply device 200, supplying power to the heating device 100 by using the power supply device 200, and baking the aerosol-generating substrate 20 by using the heating device 100;

step S400, after the aerosol-generating substrate 20 is baked, separating the heating device 100 from the power supply device 200.

In particular, a user may separate the air inlet end of the heating means 100 from the power supply means 200 prior to use of the aerosol-generating device 10, thereby exposing the air inlet 101 of the heating means 100 for addition of the aerosol-generating substrate 20. Connecting the power supply means 200 to the heating means 100 after the aerosol-generating substrate 20 has been loaded into the heating chamber 102 directly from the air inlet 101 of the heating means 100 ensures that the aerosol-generating substrate 20 has entered the heating chamber 102 sufficiently to facilitate improved aerosol generation efficiency and aerosol-generating substrate 20 utilisation efficiency. After the aerosol-generating substrate 20 has been baked, the user may then detach the inlet end of the heating device 100 from the power supply device 200 in order to clean debris generated by the aerosol-generating substrate 20. For example, after the air inlet 101 of the heating device 100 is exposed, the user can dump the residue in the heating cavity 102 out of the air inlet 101, so that the operation is convenient and fast, and the cleaning effect is good. When the power supply device 200 has insufficient power, the user can also directly separate the power supply device 200 from the heating device 100 and then connect another power supply device 200 with sufficient power to the heating device 100, thereby ensuring the continuous operation of the heating device 100. In the process, the user does not need to wait and is convenient to operate, and better user experience is achieved.

In addition, when the user stops using the aerosol-generating device 10, i.e. when the power supply device 200 is not needed to supply power to the heating device 100, the user can disconnect the power supply device 200 from the air inlet end of the heating device 100 to cut off the power supply, and then fix the power supply device 200 to the air outlet end of the heating device 100. This may ensure the integrity of the aerosol-generating device 10, avoid loss of the power supply means 200, and facilitate a user to find the power supply means 200 in time to activate the heating means 100 when he or she returns to use the aerosol-generating device 10.

Referring to fig. 14, the present application further relates to a method of heating an aerosol-generating device 10, which is based on the aerosol-generating device 10 according to any of the above embodiments, the method comprising the steps of:

step S10, loading aerosol generating substrate 20 from said air inlet 101 into the heating chamber 102 of said heating apparatus 100;

a step S20 of connecting the heating device 100 to the power supply device 200, supplying power to the heating device 100 by the power supply device 200, and controlling the heating device 100 to operate at a first power to preheat the aerosol-generating substrate 20;

step S30, upon receiving a trigger signal, controlling the heating device 100 to operate at a second power to toast the aerosol-generating substrate 20, the second power being higher than the first power.

In the above-described method of heating an aerosol-generating device 10, a user may add the aerosol-generating substrate 20 to the heating chamber 102 of the heating apparatus 100 and then connect the power supply means 200 to the heating apparatus 100, and when the power supply means 200 supplies power to the heating apparatus 100, the heating apparatus 100 may be operated at a first power to preheat the aerosol-generating substrate 20 in its heating chamber 102, and the heating apparatus 100 may be operated at a second power to bake the aerosol-generating substrate 20. Such an arrangement has the advantage that when a user is to use the aerosol-generating device 10, with the aerosol-generating substrate 20 pre-heated, the heating means 100 operating at the second power may rapidly heat up to the temperature required to bake the aerosol-generating substrate 20, facilitating rapid aerosol production without the need for a long period of time for the user, and improving the user experience.

Referring to fig. 12, in some embodiments, the aerosol-generating device 10 includes a control unit (not shown), and a heating element 110 is disposed within the heating apparatus 100, and the heating element 110 encloses the heating cavity 102. The heating assembly 110 comprises at least one heating unit 111 and the control unit may control the at least one heating unit 111 to operate at a first power to preheat the aerosol-generating substrate 20 in the heating chamber 102 when the power supply 200 is connected to the heating apparatus 100.

Specifically, in the embodiment shown in fig. 12, the heating assembly 110 includes four heating units 111 and three insulating bushes 112, and each heating unit 111 includes a heat transfer pipe 1111 and a heat generating element 1112 arranged around the heat transfer pipe 1111. The four heat transfer pipes 1111 are provided at intervals in the axial direction of the heating apparatus 100 inside the heating apparatus 100, and adjacent two heat transfer pipes 1111 are connected to each other by an insulating jacket 112. When the power supply device 200 is connected to the heating device 100, the power supply device 200 supplies power to the heating element 1112 to cause the heating element 1112 to generate heat and conduct the heat to the aerosol generating substrate 20 via the heat transfer tube 1111.

In some embodiments, when the power supply device 200 is connected to the heating device 100, the control unit may control the heating unit 111 near the outlet end of the heating device 100 to operate at a first power to preheat the aerosol-generating substrate 20. Upon receiving the trigger signal, the control unit may control the heating unit 111 near the outlet end of the heating device 100 to operate at the second power to toast the aerosol-generating substrate 20. Taking the example where the aerosol-generating substrate 20 introduced into the heating chamber 102 is a cigarette having a smoking section and a filter section, it is believed that the operation of the heating unit 111 controlling the end of the heating device 100 adjacent the air outlet 103 is to commence with the smoking of the aerosol-generating substrate 20 from the side of the smoking section adjacent the air outlet 103.

In some embodiments, when the at least one heating unit 111 is operated at the first power to preheat to a preset temperature, the at least one heating unit 111 is controlled to stop operating.

In some embodiments, the trigger signal is one or more of an action, a sound, a touch, and a terminal operation.
