The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of an aerosol-generating device provided herein. The aerosol-generating device 100 may be used to heat an atomised aerosol-generating substrate 10. It can be used in different fields, such as medical nebulization, cosmetic nebulization and the field of leisure consumption, etc. In particular, the aerosol-generating device 100 is an electronic device for generating a aerosol by heating without burning the aerosol-generating substrate (the treated plant leaf product). The aerosol-generating device 100 is heated by the elevated temperature to a temperature at which the aerosol-generating substrate 10 can produce an aerosol but is not sufficiently combustible to enable the aerosol-generating substrate 10 to produce the aerosol desired by the user without combustion.
Therein, the aerosol-generating device 100 comprises a housing 101 and a heating assembly 20 and a power supply assembly 30 arranged within the housing 101. A heating assembly 20 for heating the aerosol-generating substrate 10 to form an aerosol, a power supply assembly 30 comprising a battery 31, an airflow sensor (not shown), a control circuit board (not shown), etc.; the power supply assembly 30 is arranged to supply power to the heating assembly 20 and to control the operation of the heating assembly 20 to heat the aerosol-generating substrate 10 to form an aerosol. Wherein the airflow sensor is configured to detect a change in airflow in the aerosol-generating device 100, and the control circuit board activates the battery 31 to supply power to the heating assembly 20 according to the change in airflow detected by the airflow sensor. In an alternative embodiment, the airflow sensor may be absent, and the control circuit board activates the battery 31 to power the heating assembly 20 according to the control signal.
The inventor of the application finds that in the existing heating assembly adopting the periphery heating, the heating element is isolated from the magnetic field generator through air or an isolating material, however, in the process of heating the aerosol generating substrate by the heating assembly, the heat of the heating element can be conducted to the magnetic field generator through the air or the isolating material, so that the temperature of the magnetic field generator is too high, and the work of the magnetic field generator is influenced. In addition, the heat dissipation of the heating element is large, which affects the heating efficiency, increases the power consumption of the aerosol generating device, and also causes the temperature of the housing of the aerosol generating device to be too high, which affects the user experience.
To this end, the present application provides a heating assembly 20, see fig. 2-5, fig. 2 being a schematic structural view of an embodiment of the heating assembly in the aerosol-generating device of fig. 1; FIG. 3 isbase:Sub>A cross-sectional view of the heating assembly shown in FIG. 2 taken along line A-A; figure 4 is a schematic structural view of another embodiment of a heating assembly in the aerosol-generating device of figure 1; fig. 5 isbase:Sub>A cross-sectional view of the heating assembly shown in fig. 4 taken along linebase:Sub>A-base:Sub>A.
Specifically, the heating assembly 20 includes an inner tube 21, an outer tube 22, a heating element 23, and a magnetic field generator 24. The magnetic field generator 24 is operable to generate an electromagnetic field in an energized condition, and the heating element 23 is located within the electromagnetic field and generates an induced current under the influence of the electromagnetic field, thereby generating induced heat to heat the aerosol-generating substrate 10. The outer tube 22 is sleeved outside the inner tube 21 and defines a heat insulation cavity 201 with the inner tube 21, and the air pressure in the heat insulation cavity 201 is smaller than the external atmospheric pressure; the heating element 23 is positioned in the insulated chamber 201 and is disposed on the outer surface of the inner tube 21; a magnetic field generator 24 is disposed outside the outer tube 22. Specifically, by setting the air pressure in the heat insulation cavity 201 to be smaller than the external atmospheric pressure, the heating element 23 is located in the heat insulation cavity 201 and is arranged on the outer surface of the inner tube 21, so that heat generated by the heating element 23 can be transferred through the inner tube 21 and is not easily transferred to the outer tube 22, heat loss is reduced, power consumption is reduced, and atomization efficiency is improved; and magnetic field generator 24 sets up in the outside of outer tube 22, can avoid the heat transfer that heating element 23 produced to magnetic field generator 24 to lead to magnetic field generator 24 high temperature, influence work.
It is understood that the material of the heating element 23 is a material capable of generating an induced current under the action of an electromagnetic field, for example, the heating element 23 is made of a ferromagnetic material, such as iron, nickel, cobalt, stainless steel, iron chromium cobalt, aluminum nickel cobalt, neodymium iron boron, etc.; or a composite material mixed with ferromagnetic materials, such as nichrome, copper-iron alloy, nichrome, iron-chromium-aluminum alloy, and the like. Wherein, the heating element 23 can be directly fixed on the outer surface of the inner tube 21; the heating element 23 may also be a metal film formed on the outer surface of the inner tube 21 by screen printing, coating or deposition (physical vapor deposition, chemical vapor deposition).
In this embodiment, the material of the inner tube 21 and the outer tube 22 is a magnetic insulating material, such as insulating ceramic or glass. Specifically, when the magnetic field generator 24 is in the energized state, no induced current is generated in the inner tube 21 and the outer tube 22, and thus no induction heating is generated. Thereby preventing heat generated on the outer tube 22 from being transferred to the magnetic field generator 24 and the housing 101. The aerosol-generating substrate 10 is heated only by the heat transferred from the inner tube 21 by the heating element 23. In the present embodiment, the inner tube 21 and the outer tube 22 have good thermal stability and rigidity, for example, the bending strength of the inner tube 21 and the outer tube 22 made of insulating ceramics can be more than 600MPa, the thermal stability can exceed 450 degrees, the fire resistance can be higher than 1450 degrees, and the thermal conductivity of the inner tube 21 can be 4-18W/(m.k).
In another embodiment, the material of the outer tube 22 is a magnetic insulating material, and the material of the inner tube 21 is a material capable of generating an induced current under the action of an electromagnetic field. In particular, when the magnetic field generator 24 is energised, no induced current is generated in the outer tube 22 and therefore no induction heating occurs, and the induction heating generated by the heating element 23 and the induction heating generated in the inner tube 21 together heat the aerosol-generating substrate 10 and thereby improve the heating and atomising efficiency.
In one embodiment, magnetic field generator 24 is an electronic device or an electromagnetic coil capable of generating an electromagnetic field. When the magnetic field generator 24 is a solenoid, the solenoid is disposed around the outside of the outer tube 22. The electromagnetic coil is capable of generating an electromagnetic field under energized conditions, thereby causing inductive heating of a heating element 23 located within the electromagnetic field.
In one embodiment, referring to fig. 2, the electromagnetic coil includes a first electromagnetic coil 241 and a second electromagnetic coil 242 arranged at intervals, the first electromagnetic coil 241 is arranged at the first end of the outer tube 22, and the second electromagnetic coil 242 is arranged at the second end of the outer tube 22. The first electromagnetic coil 241 and the second electromagnetic coil 242 can be operated independently or simultaneously, for example, the power supply assembly 30 can selectively and independently control the first electromagnetic coil 241 and the second electromagnetic coil 242 to operate according to the user's requirement, so that part of the heating element 23 can be heated by induction, and part of the heating element is not heated by induction because the heating element is not in the electromagnetic field, thereby effectively controlling the atomization amount. In this embodiment, the heating element 23 is of a sectional design, the heating element 23 includes a first sub-heating section 231 and a second sub-heating section 232 which are arranged at intervals, and the first sub-heating section 231 and the first electromagnetic coil 241 are arranged correspondingly to ensure that the first sub-heating section 231 is always located in the electromagnetic field generated by the first electromagnetic coil 241 to generate an induced current; the second sub-heating section 232 and the second electromagnetic coil 242 are correspondingly disposed to ensure that the second sub-heating element 232 is always located in the electromagnetic field generated by the second electromagnetic coil 242 to generate an induced current, thereby ensuring an atomization effect. Of course, in the present embodiment, the heating element 23 may not be designed in a sectional manner, as long as the heating element 23 is ensured to be located in the electromagnetic field generated by the first electromagnetic coil 241 and the second electromagnetic coil 242, which is not limited herein.
In an embodiment, since the aerosol-generating substrate 10 contains a plurality of component substances, the boiling point temperatures of different component substances are different, the power supply module 30 may also output different powers to the first electromagnetic coil 241 and the second electromagnetic coil 242, so that the first electromagnetic coil 241 and the second electromagnetic coil 242 generate different electromagnetic field strengths, and further the heat generated by the induction heating of the heating element 23 located in different electromagnetic field strengths is different, thereby satisfying the differential heating of different component substances in the aerosol-generating substrate 10, and improving the atomization effect.
Of course, the number of the electromagnetic coils may also be 1 (see fig. 4), or the number of the electromagnetic coils may also be more than two. When the number of the electromagnetic coils is greater than or equal to two, the plurality of electromagnetic coils are arranged at intervals, and the number can be specifically selected according to the actual situation, and is not limited herein. Wherein, regardless of the number of the one or more electromagnetic coils, the projection of the one or more electromagnetic coils onto the outer surface of the inner tube 21 overlaps the heating element 23 to ensure that the heating element 23 is always within the electromagnetic field generated by the electromagnetic coils to ensure a heated atomising effect on the aerosol-generating substrate 10.
In one embodiment, the number of the electromagnetic coils is multiple and the heating elements 23 include multiple sub-heating sections arranged at intervals, the number of the multiple sub-heating sections is the same as the number of the multiple electromagnetic coils, and the multiple sub-heating sections are arranged in one-to-one correspondence with the multiple electromagnetic coils. Specifically, the projection of each electromagnetic coil on the outer surface of the inner tube 21 overlaps with its corresponding sub-heating section, so that each sub-heating section is located within the electromagnetic field generated by its corresponding electromagnetic coil.
In one embodiment, referring to fig. 2-3, the heating element 23 is spaced from the outer tube 22. Specifically, the both ends of outer tube 22 form throat portion 221, outer tube 22 passes through throat portion 221 and is connected with inner tube 21, the both ends and the throat portion 221 interval of heating element 23 set up, and heating element 23 and the equal interval setting of other parts of outer tube 22, thereby when making heating element 23 produce induction heating, heat on the heating element 23 can not with outer tube 22 direct contact and with heat transfer to outer tube 22, avoid with heat transfer to solenoid and casing 101, lead to the solenoid high temperature, reduce solenoid's work efficiency, and avoid casing 101 high temperature, influence user experience.
In one embodiment, the inner tube 21 extends at least partially out of the outer tube 22. Referring to figures 1-3, the inner tube 21 is of a hollow cylindrical shape for receiving the aerosol-generating substrate 10, and when the aerosol-generating substrate 10 is received in the inner tube 21, the side walls of the aerosol-generating substrate 10 conform to the inner surface of the inner tube 21, and the aerosol-generating substrate 10 extends at least partially out of the inner tube 21, which may increase the contact area with the aerosol-generating substrate 10, thereby increasing the heat atomisation effect on the aerosol-generating substrate 10.
In another embodiment, to simplify the process, both ends of the inner tube 21 are flush with both ends of the outer tube 22, see fig. 5.
In an embodiment, referring to fig. 6-8, fig. 6 is a schematic structural view of a further embodiment of a heating assembly in the aerosol-generating device of fig. 1; FIG. 7 isbase:Sub>A cross-sectional view of the heating assembly shown in FIG. 6 taken along line A-A; fig. 8 is a cross-sectional view of the heating assembly shown in fig. 6 taken along line B-B. The outer surface of the outer tube 22 also has a plurality of circumferentially disposed supports 222, and the electromagnetic coil is wound around the outer tube 22 and disposed on the supports 222. Specifically, the plurality of supporting pieces 222 are arranged on the outer surface of the outer tube 22 along the circumferential direction of the outer tube 22, each supporting piece 222 extends along the height direction of the outer tube 22, and the electromagnetic coil is wound around the outer tube 22 and arranged on the supporting pieces 222, so that the electromagnetic coil and the outer tube 22 are arranged at intervals, heat generated on the heating element 23 is further prevented from being transferred to the electromagnetic coil, and normal operation of the electromagnetic coil is ensured.
In one embodiment, one side of each support 222 may be connected to the outer surface of the outer tube 22. In another embodiment, referring to fig. 7, both ends of each support 222 are connected to the outer surface of the outer tube 22, and the remaining portions are spaced apart from the outer tube 22.
In the above embodiments, the insulating chamber 201 in the heating assembly 20 may be a vacuum insulating chamber 201. It can be understood that, the conduction of vacuum to heat is substantially zero, by disposing the heating element 23 in the vacuum heat insulation cavity 201 and on the outer surface of the inner tube 21, the heating element 23 is disposed at an interval with the outer tube 22, so that the heat generated on the heating element 23 can only be transferred through the inner tube 21, but cannot be transferred to the outer tube 22, thereby reducing the heat loss of the heating element 23, reducing the power consumption of the aerosol generating device 100, improving the heating and atomizing efficiency, and simultaneously avoiding the heat generated by the heating element 23 being transferred to the magnetic field generator 24 and the housing 101 outside the outer tube 22, resulting in the temperature of the magnetic field generator 24 and the housing 101 being too high, and affecting the work of the magnetic field generator 24 and the user experience.
In one embodiment, the aerosol-generating device 100 further comprises a magnetic shielding layer (not shown) disposed between the magnetic field generator 24 and the housing for distorting or shielding the electromagnetic field generated by the magnetic field generator 24 to reduce radiation of the electromagnetic field out of the aerosol-generating device 100, which may adversely affect a user.
The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
