They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0033] Please see Figures 1 to 5 This utility model proposes a heating assembly, including: at least two heating elements 1, a ceramic body 2 and a control unit (not shown in the figure), wherein the heating ends of the two heating elements 1 are in contact with the ceramic body 2, and the control unit controls the heating elements 1 to switch between parallel and series states.

[0034] It should be noted that the control unit includes electronic components such as MCU and MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor). The two heating elements 1, together with the MCU, MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) and other electronic components, constitute the working circuit. The control unit controls the switching of the MOSFET to realize the series and parallel switching of the two heating elements 1.

[0035] In practical applications, according to Joule's law, heating power is directly proportional to the square of the current. Therefore, when a user desires a rich aerosol inhalation experience, the MCU controls the MOSFET to connect the positive and negative terminals of the two heating elements 1 sequentially, forming a series circuit. In this case, the resistance of the entire circuit is the sum of the resistances of the two heating elements 1, and the heating efficiency of the heating assembly is at its maximum. When a user desires a smooth aerosol inhalation experience, the MCU controls the MOSFET to connect the positive and negative terminals of the two heating elements 1 in parallel. In this case, the total resistance of the entire circuit is less than the resistance of any single heating element 1, and the heating efficiency of the heating assembly is at its minimum.

[0036] The heating component proposed in this embodiment adjusts the heating power of the heating component by switching the two heating elements 1 in parallel or in series. This allows users to adjust the heating power of the heating component according to different usage scenarios or personal preferences, thereby adjusting the concentration and temperature of the aerosol, improving the aerosol generation efficiency, inhalation taste, and user experience.

[0037] Please see Figure 2 and Figure 3 The ceramic body 2 is provided with an atomizing cavity 21 that runs through its opposite ends, and the heating element 1 is located in the atomizing cavity 21.

[0038] Specifically, when the heating element 1 is powered on, the heat it generates acts on the ceramic body 2 through heat conduction, and then convects and exchanges heat with the gas in the atomizing chamber 21 and the tiny particles generated after the atomizing matrix is ​​atomized to form an aerosol. At the same time, the gas itself is also heated in the process of convective heat exchange, which improves the inhalation taste of the aerosol.

[0039] Please see Figure 3 and Figure 4 The inner wall of the atomizing chamber 21 is provided with an atomizing surface 22, and the heating element 1 is attached to the atomizing surface 22.

[0040] Specifically, the heat generated by the heating element 1 after being powered on is first transferred to the atomizing surface 22 through thermal conduction, reducing the surface tension of the atomizing matrix flowing over it, promoting the rapid evaporation of the atomizing matrix and the formation of tiny particles, thus improving atomization efficiency. At the same time, within the atomization chamber 21, the high-temperature atomizing surface 22 undergoes convective heat exchange with the low-temperature gas. While absorbing heat, the gas carries away the atomized particles to form aerosols, thereby improving the quality of aerosol formation.

[0041] Please see Figure 4 The heating element 1 includes a heating body 11 and electrodes 12 connected to both ends of the heating body 11. The heating body 11 is attached to the atomizing surface 22.

[0042] Specifically, the heating element 11 is attached to the atomizing surface 22, so that the heat it generates can directly act on the atomizing surface 22, improving atomization efficiency. At the same time, the uniformly heated atomizing surface 22 allows the atomizing matrix to be uniformly heated and evaporated, forming fine and uniform atomized particles, thus improving atomization quality.

[0043] Please see Figure 6 In one embodiment, the heating element 1 includes two identical heating bodies 11 and electrodes 12 respectively connected to the two ends of the two heating bodies 11. The two heating bodies 11 are connected by a connecting part 115, which is made of a high thermal conductivity material, thereby increasing the heating area of ​​the heating element 1 and improving the generation efficiency and quality of aerosols.

[0044] In this embodiment, the heating element 11 is planar.

[0045] Specifically, the heating element 11 is planar, which makes the heat of the atomizing surface 22 evenly distributed, avoids local overheating of the atomizing surface 22 or insufficient heating of the atomizing matrix, and improves the atomization quality of the atomizing matrix.

[0046] Please see Figure 4 The heating element 11 has a plurality of mesh holes 111, the shape of which is trapezoidal, circular, elliptical or a combination of at least two of them.

[0047] Specifically, after the heating element 11 is energized, it generates heat that acts on the atomizing surface 22. Because the heating element 11 has mesh openings 111, the airflow and the tiny particles generated after atomization of the atomizing matrix flow within the mesh openings 111, forming convective heat transfer, accelerating the heat transfer rate and improving the aerosol generation efficiency. In one embodiment, multiple mesh openings 111 are arranged regularly on the heating element 11 to avoid localized overheating and improve the quality of aerosol generation. Preferably, in this embodiment, the mesh openings 111 are hexagonal in shape.

[0048] Please see Figure 4 and Figure 6 The heating element 11 includes multiple first heating segments 112 and multiple second heating segments 113, which are connected in series in an alternating manner, and the first heating segments 112 and the second heating segments 113 are bent and connected.

[0049] Specifically, the first heating segment 112 or the second heating segment 113 is located at both ends of the heating element 11. The two ends of the remaining first heating segments 112 are respectively connected to one end of two adjacent second heating segments 113, and the two ends of the remaining second heating segments 113 are respectively connected to one end of two adjacent first heating segments 112, thus forming an interleaved series connection. The first heating segments 112 and the second heating segments 113 are bent and connected, making the heating element 11 bend into a wave shape, which makes the heating length of the heating element 11 longer. At the same time, the heating fields generated by the first heating segments 112 and the second heating segments 113 are superimposed, so that the superimposed area of ​​the heating field has a higher atomization temperature, thereby improving the atomization efficiency of the heating component.

[0050] Please refer to it again. Figure 4 and Figure 6 The heating element 11 also includes a plurality of heat dissipation sections 114, the ends of which are connected to the connection between the first heating section 112 and the second heating section 113.

[0051] Specifically, when the heating element 11 is working, a large amount of heat is generated at the connection between the first heating segment 112 and the second heating segment. Connecting the end 114 of the heat dissipation part 114 to the connection between the first heating segment 112 and the second heating segment 113 can absorb the heat generated at the connection between the first heating segment 112 and the second heating segment 113 and transfer it to the atomizing surface 22, thereby improving the atomization efficiency of the heating component.

[0052] Please see Figure 3 and Figure 4 Air guide surfaces 23 are provided on both sides of the spray nozzle of the atomizing chamber 21 to ensure that the airflow speed on both sides of the spray nozzle is consistent, reduce the condensation of aerosol at the spray nozzle, and improve the user's inhalation experience.

[0053] This invention also proposes an atomizing core, including the heating component described above.

[0054] Specifically, the heating element is applied to the atomizer core, so the beneficial effects of the atomizer core are the same as those of the heating element.

[0055] This invention also proposes an aerosol generating device, including a power supply component and an atomizing core as described above, wherein the power supply component is electrically connected to the atomizing core.

[0056] Specifically, the atomizing core is used in the aerosol generating device, so the beneficial effects of the aerosol generating device are the same as those of the atomizing core.

[0057] Compared with the prior art, the heating component proposed in this utility model can adjust the heating power of the heating component by switching the two heating elements 1 in parallel or in series. This allows users to adjust the heating power of the heating component according to different usage scenarios or personal preferences, thereby adjusting the concentration and temperature of the aerosol, improving the aerosol generation efficiency, the inhalation taste, and the user's experience.

[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
