Description

Technical Field

[0001] This application relates to the field of aerosol generation device technology, specifically to an aerosol generation device and a heating core assembly. Background Technology

[0002] Aerosol generating devices are used to generate aerosols for users to inhale. One current aerosol generating device includes a heating core with a liquid storage chamber where the aerosol generating liquid is stored. The heating element of the heating core heats the aerosol generating liquid to generate aerosols. To enrich the flavor of the aerosols, current aerosol generating liquids are usually made by mixing two or more flavors. While this produces a wider variety of flavors, in some applications, different flavors of aerosol generating liquids require different heating temperatures. Heating different flavors of aerosol generating liquids at the same temperature can easily lead to carbonization and deposition of the heating core, shortening its lifespan. Utility Model Content

[0012] Furthermore, in some embodiments, the substrate further includes a protective shell, in which the first shell and the second shell are inserted, and the protective shell, the first shell, and the second shell form the mixing cavity.

[0013] Furthermore, in some embodiments, the heat-conducting component of the first heating core is a porous ceramic body or a liquid-conducting cotton, and / or the heat-conducting component of the second heating core is a porous ceramic body or a liquid-conducting cotton.

[0034] The embodiments described in the detailed implementation can be combined in any suitable manner without contradiction.

In order to avoid unnecessary repetition, the various possible combinations of the embodiments will not be described separately.

[0035] It should be noted that the conductive, interconnected and connected forms described in this application are not limited to empty channels that allow the aerosol generating liquid to pass through, but also include channels filled with porous materials that allow the aerosol generating liquid to pass through.

[0036] To address the problem that using the same heating element for different flavored aerosol generating liquids can shorten the lifespan of the heating element, this application provides a heating element assembly with two or more heating elements. This assembly has independent liquid storage chambers capable of storing different aerosol generating liquids separately. By heating the aerosol generating liquids in different storage chambers using different heating elements, the temperature of the heating element can be matched to that of the aerosol generating liquid, thus improving the problem of easy damage to the heating element. The heating element assembly and aerosol generating device of this application will be described in detail below with reference to the accompanying drawings.

[0037] In some embodiments, please refer to Figures 1 to 3 The aerosol generating device includes a power supply module (not shown in the figure) and a heating core assembly 100, wherein the power supply module supplies power to the heating core assembly 100. The heating core assembly 100 includes a base 1, a first heating core 2 and a second heating core 3, both of which are mounted on the base 1.

[0038] The substrate 1 has a first liquid storage chamber 11 and a second liquid storage chamber 12, both of which are used to store aerosol generating liquid. In addition, the first liquid storage chamber 11 and the second liquid storage chamber 12 are independent of each other, that is, the first liquid storage chamber 11 and the second liquid storage chamber 12 are separated and not connected to each other, so as to prevent the aerosol generating liquid in the two from mixing.

[0039] Both the first heating element 2 and the second heating element 3 include a liquid guiding component and a heating component. The heating component is used to heat the aerosol generating liquid to generate aerosols. For ease of description, the heating component of the first heating element 2 is a first heating element 21, and the liquid guiding component of the first heating element 2 is a first liquid guiding component 22. The first liquid guiding component 22 communicates with the first liquid storage chamber 11 and is used to guide the aerosol generating liquid in the first liquid storage chamber 11 to the first heating element 21. The first heating element 21 is used to heat the aerosol generating liquid guided by the first liquid guiding component 22 to generate aerosols. The heating element of the second heating element 3 is a second heating element 31, and the liquid guiding component of the second heating element 3 is a second liquid guiding component 32. The second liquid guiding component 32 communicates with the second liquid storage chamber 12 and is used to guide the aerosol generating liquid in the second liquid storage chamber 12 to the second heating element 31. The second heating element 31 is used to heat the aerosol generating liquid guided by the second liquid guiding component 32 to generate aerosols.

[0040] The substrate 1 also has a mixing chamber 13, which has an aerosol outlet 131. The mixing chamber 13 is located between the first heating core 2 and the second heating core 3. The aerosol generated by the first heating core 2 and the aerosol generated by the second heating core 3 are mixed in the mixing chamber 13 and then drawn out through the aerosol outlet 131.

[0041] Since the first storage chamber 11 and the second storage chamber 12 can store aerosol generating liquids of different flavors as needed, the aerosol generating liquid in the first storage chamber 11 can be heated by the first heating element 21 to generate aerosol, and the aerosol generating liquid in the second storage chamber 12 can be heated by the second heating element 31 to generate aerosol. After the aerosol generated by the first heating element 21 and the aerosol generated by the second heating element 31 are mixed in the mixing chamber 13, they can be drawn out through the aerosol outlet 131. The heating core assembly 100 of this application can use a suitable heating core to heat the aerosol generating liquid according to its characteristics, so that the heating temperature of the heating core is more matched with that of the aerosol generating liquid, and the heating core is less prone to problems such as carbon buildup, thus improving the technical problem of short heating core life in current aerosol generating devices.

[0042] Furthermore, the gap between the first heating core 2 and the second heating core 3 forms a mixing chamber 13. This makes it difficult for the aerosol generated by the heating of the first heating core 2 to enter the second heating core 3, and vice versa, further improving the carbonization deposition problem of the first heating core 2 and the second heating core 3.

[0043] Regarding the type of heating core, existing types can be used. For example, in some embodiments, the heating core is a ceramic heating core, and the liquid guiding element of this heating core is a porous ceramic body. Besides ceramic heating cores, in some embodiments, the heating core can also be a liquid-guiding cotton heating core, meaning the liquid guiding element of the heating core can also be liquid-guiding cotton. Regarding the shape of the heating core, in some embodiments, the heating core is a cylindrical heating core, with the liquid guiding element in a cylindrical shape, and the cylindrical heating core forming an aerosol channel that communicates with the mixing chamber 13. In some embodiments, the heating core can also be a flat heating core, with the liquid guiding element in a flat shape.

[0044] In one embodiment, the rated power of the first heating element 21 is less than the rated power of the second heating element 31. This results in different heating temperatures for the first heating element 21 and the second heating element 31, allowing for the selection of a suitable aerosol generating liquid as needed. In some embodiments, the first heating element 21 and the second heating element 31 can be connected in parallel or in series. In some embodiments, the power supply module includes a power supply battery that supplies power to the first heating element 21 and the second heating element 31.

[0045] It should be noted that the first heating core 2 and the second heating core 3 can be of the same type or different types. Understandably, in some embodiments, the ceramic heating core and the liquid-conducting cotton heating core are applicable to different temperatures. For example, please refer to... Figures 3 to 5 The first heating core 2 is a ceramic heating core with a heating temperature of 160°C to 200°C. The first liquid storage chamber 11 stores a matching aerosol generating liquid, such as an aerosol generating liquid containing macromolecular substances (e.g., sweeteners). The second heating core is a liquid-conducting cotton heating core with a heating temperature of 220°C to 260°C. The second liquid storage chamber 12 stores a matching aerosol generating liquid, such as an aerosol generating liquid containing small molecule substances (e.g., low-molecular-weight flavorings).

[0046] Specifically, in some embodiments, please refer to Figures 3 to 6 The first heating element 2 is a flat heating element, and the second heating element 3 is a cylindrical heating element. The structure of the heating element is a mature existing technology. To avoid going into too much detail, the following is a brief description of the structure of the flat heating element used in the first heating element 2 and the cylindrical heating element used in the second heating element 3.

[0047] Please refer to Figures 3 to 5 The first heating core 2 is generally flat, and one side of the first heating element 21 is attached to the first liquid guiding element 22. The first liquid guiding element 22 can be made of liquid guiding cotton or porous ceramic. The first heating element 21 can be any feasible form such as a heating mesh or a heating plate.

[0048] Please refer to Figure 3 and Figure 6 The second liquid guiding element 32 is made of a porous material, such as porous absorbent cotton or porous ceramic. The second liquid guiding element 32 surrounds the outer periphery of the second heating element 31, and the second liquid storage cavity 12 is located around the second liquid guiding element 32. In some embodiments, to control the speed at which the aerosol generating liquid enters the second liquid guiding element 32, the second heating core 3 typically also includes a heating core shell (not shown in the figure). Both the second liquid guiding element 32 and the second heating element 31 are located within the heating core shell, which has a liquid passage hole for the aerosol generating liquid to pass through. The second liquid guiding element 32 communicates with the second liquid storage cavity 12 through the liquid passage hole. The aerosol generating liquid enters the second liquid guiding element 32 through the liquid passage hole, and then comes into contact with the second heating element 31 and is heated to generate an aerosol. Regarding the second heating element 31, the second heating element 31 can take any feasible form, such as a heating wire mesh, multiple parallel heating wires, etc.

[0049] Regarding the arrangement of the first heating element 2 and the second heating element 3, please refer to some embodiments. Figure 3 In the state where the aerosol generating device is being aspirated, the first heating core 2 and the second heating core 3 are arranged vertically. Of course, in some other embodiments, the first heating core 2 and the second heating core 3 can also be arranged horizontally when the aerosol generating device is being aspirated. In some other embodiments, in addition to the first and second heating cores, the number of heating cores in the heating core assembly can be three or more.

[0050] Regarding the configuration of the mixing chamber 13, please refer to some embodiments. Figure 3 The substrate 1 includes a first housing 14 and a second housing 15. A first liquid storage chamber 11 is located in the first housing 14, and a second liquid storage chamber 12 is located in the second housing 15. A first heating core 2 is installed in the first housing 14, and a second heating core 3 is installed in the second housing 15. The first housing 14 and the second housing 15 are fixedly assembled, and a mixing chamber 13 is located between the first housing 14 and the second housing 15. Because the first housing 14 and the second housing 15 are fixedly assembled, it is more convenient to form the substrate 1 compared to a one-piece molding method. Of course, in some other embodiments, the first housing 14 and the second housing 15 can also be one-piece molded.

[0051] To improve the reliability of fixing the first housing 14 and the second housing 15, in some embodiments, please refer to... Figures 1 to 3 The substrate 1 also includes a protective shell 16, in which a first shell 14 and a second shell 15 are inserted. The protective shell 16 has a communicating hole 161 that communicates with the aerosol outlet 131. The protective shell 16, the first shell 14, and the second shell 15 form a mixing chamber 13. That is, the protective shell 16 covers the first shell 14 and the second shell 15 and seals the mixing chamber 13, so that the aerosol in the mixing chamber 13 can only be discharged through the aerosol outlet 131.

[0052] Furthermore, in some embodiments, the first housing 14 and the second housing 15 are detachably fixed. This allows for disassembly and maintenance. Specifically, the first housing 14 and the second housing 15 can be fixed using feasible detachable methods such as magnetic attraction, snap-fit, or fastener fixation.

[0053] In some embodiments, please refer to Figure 3 and Figure 4 To facilitate the installation of the first housing 14 and the second housing 15, the first housing 14 and the second housing 15 are inserted into each other along the arrangement direction of the first heating core 2 and the second heating core 3. The first housing 14 has a protruding portion 141, and the second housing 15 has a slot 151. After the protruding portion 141 is positioned and inserted into the slot 151, the first housing 14 and the second housing 15 are magnetically secured. In some embodiments, the mixing chamber 13 is located in the slot 151.

[0054] In some other embodiments, the mixing chamber 13 may also be formed by the first housing 14 and the second housing 15, in which case the protective housing 16 is not required. In some other embodiments, the first housing 14 and the second housing 15 may not be directly fixedly connected, and the first housing 14 and the second housing 15 may be independently fixed to the protective housing 16.

[0055] In some embodiments, please refer to Figure 3 The number of aerosol outlets 131 is one. In some other embodiments, the number of aerosol outlets 131 may be two or more, and the two or more aerosol outlets 131 form a turbulence generating structure for generating turbulence in the aerosols. The turbulence generating structure enables the aerosols to generate turbulence, thereby making the aerosols generated from different types of aerosol generating liquids mix more uniformly. Of course, in some other embodiments, a turbulence generator may be installed at the aerosol outlet 131 instead of the turbulence generating structure formed by two or more aerosol outlets 131. Specifically, the turbulence generator may be an orifice plate type turbulence generator.

[0056] In one embodiment of the heating core assembly, the structure of the heating core assembly is the same as that of the heating core assembly 100 described in any of the above embodiments, and will not be repeated here.

[0057] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
