In the following embodiments, many specific details are described in order to provide a thorough understanding of the application. However, it will be apparent to those skilled in the art that the specific features described in the embodiments can be replaced by alternative features or elements, or can be omitted in some cases.

The "connection" and "coupling" in this application include direct and indirect connections (couplings) unless otherwise specified.

[0030] Please refer to Figures 1 to 8 The application provides an aerosol generating substrate A atomization device (hereinafter referred to as "atomization device") which can heat the aerosol generating substrate A to form an aerosol for the user to use.

[0031] It is noted that the term aerosol as used herein refers to a dispersion of solid particles or liquid particles in a gas. As used herein, "aerosol" can be used to refer generally to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form to an inhalable form that includes suspended solid or liquid drug particles.

[0032] As used herein, the term "aerosol generating substrate A" refers to any suitable compound or mixture of compounds that facilitates aerosol (e.g. stable aerosol that is substantially resistant to thermal degradation at the operating temperature of the system) formation in use. Suitable aerosol generating substrates A are well known in the art and include, but are not limited to: polyhydric alcohols such as triethylene glycol, 1,3-butanediol and glycerol; esters of polyhydric alcohols such as glycerol mono-, di- or triacetate; and aliphatic esters of mono-, di- or poly-carboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate. The aerosol generating substrate A can include nicotine. The aerosol generating substrate A can include water. The aerosol generating substrate A can include glycerol (also known as glycerine) which has a higher boiling point than nicotine. The aerosol generating substrate A can include propylene glycol. The aerosol generating substrate A can include plant-based material. The aerosol generating substrate A can include homogenized plant-based material. The homogenized plant-based material can contain volatile compounds. These compounds can be released from the aerosol generating substrate A upon heating.

[0033] The atomization device comprises a shell assembly 100, a power supply assembly 200 and a heating device 300. The shell assembly 100 can be understood as a collection constituting the overall outline of the atomization device. The shell assembly 100 provides protection for the structure inside the atomization device, and also facilitates the carrying and transportation of the atomization device. The power supply assembly 200 and the heating device 300 are electrically connected, which can supply power to the heating device 300 and also control the working temperature or power of the heating device 300.

[0034] Since the shell assembly 100 and the power supply assembly 200 are prior art and not the focus of the protection scheme of the present application, they will not be described in detail here. The heating device 300 will be described in detail below.

[0035] Please refer to Figure 2 and Figure 3The heating device 300 includes a support assembly 310, a heating assembly 320, and a reflector 330. The support assembly 310 has an air inlet that allows it to communicate with the external environment, enabling outside air to enter the heating device 300 through the air inlet when the user inhales. The heating assembly 320 is disposed inside the support assembly 310 and includes a heat-conducting element 321 and a heating element 322. The heat-conducting element 321 is a hollow structure with openings at both ends. The heating element 322 is disposed at the opening of the heat-conducting element 321 away from the air inlet and together with the heat-conducting element 321 forms a heating cavity 323 for containing the aerosol generation matrix A. The heating cavity 323 has a connection between the air inlet and the air... The airflow channel 324 inside the aerosol generating matrix A, the heating element 322 for heating after being energized, the heat-conducting element 321 for absorbing at least part of the heat from the heating element 322 and transferring at least part of the absorbed heat to the heating cavity 323, the heating cavity 323 for containing the aerosol generating matrix A, after the heat from the heating element 322 is transferred to the heating cavity 323, the aerosol generating matrix A can be heated by contact heat conduction and by hot airflow, the reflector 330 is disposed inside the support assembly 310 and outside the heat-conducting element 321, the reflector 330 is used to reflect the heat radiated outward by the heat-conducting element 321 and / or the heating element 322.

[0036] It should be noted that in this application, "inward" refers to the direction toward the center of the heating cavity 323, and "outward" refers to the direction away from the center of the heating cavity 323.

[0037] It is understandable that, since the heat-conducting component 321 and the heating component 322 have thermal radiation, they can radiate some heat outward. The direction of heat transfer is opposite to the direction of heat transfer to the heating chamber 323, and it cannot be fully utilized by the heating chamber 323, that is, it cannot be absorbed and used by the aerosol generating matrix A, thus causing heat loss and increasing the power consumption of the power supply component 200.

[0038] To address the aforementioned issues, this application incorporates a reflector 330 on the outer side of the heat-conducting component 321. Due to the reflector 330, the heat transferred to it is reflected back in the opposite direction, meaning the outward heat radiation from the heat-conducting component 321 is reflected back to the heat-conducting component 321, and then ultimately transferred to the aerosol-generating matrix A via the heat-conducting component 321. Similarly, the outward heat radiation from the heating element 322 is reflected back to the heating element 322, and then ultimately transferred to the aerosol-generating matrix A via the heat-conducting component 321. This reduces heat loss due to heat radiation, improves heat utilization, and consequently reduces the power consumption of the power supply component 200, thereby lowering the operating cost of the atomizing device.

[0039] Due to the arrangement of the airflow channel 324, the outside air can be heated to form a hot airflow when it passes through the heating chamber 323. The hot airflow enters the interior of the aerosol generation matrix A, realizing airflow heating. The aerosol generation matrix A is also contained in the heating chamber 323 and is heated by heat conduction with the heat-conducting component 321. The use of heat conduction and airflow heating can improve the heating efficiency and effectively ensure that the aerosol generation matrix A is fully and uniformly heated.

[0040] Since the heating element 322 is located at one end of the heat-conducting element 321 as a heat source, according to the structural characteristics of the atomizing device in use (with aerosol generating matrix A installed), the heat source is located at the end of the aerosol generating matrix A, which can increase the heat at the end of the aerosol generating matrix A, accelerate the aerosol generation speed, and reduce the temperature near the air outlet 311 to avoid scalding the user.

[0041] In some embodiments, the heat-conducting element 321 is made of a material with high thermal conductivity and capable of transmitting infrared radiation, such as aluminum nitride, silicon carbide, or aluminum oxide. Preferably, the heat-conducting element 321 has a thermal conductivity >15W / (K*m) and an emissivity >0.5. The heat-conducting element 321 can fully absorb the heat from the heating element 322 and the radiant heat reflected by the reflector 330, thereby improving the heat utilization rate of the atomizing device.

[0042] In some embodiments, the reflector 330 is made of a material with high thermal conductivity and low emissivity, such as aluminum alloy or silver. Preferably, the reflector 330 has a thermal conductivity >15W / (K*m) and an emissivity <0.3. The low emissivity can increase the internal temperature of the reflector 330, allowing more heat to be transferred to the aerosol generating matrix A, thereby improving the heat utilization rate of the atomizing device.

[0043] In some embodiments, the heating element 322 is made of a high thermal conductivity material, such as aluminum alloy, aluminum nitride, silicon carbide, alumina, or stainless steel. Preferably, the thermal conductivity of the heating element 322 is >15W / (K*m), which can transfer more heat to the heat-conducting element 321 or the heating chamber 323, thereby allowing more heat to be transferred to the aerosol generating matrix A, thus improving the heat utilization rate of the atomizing device.

[0044] In some embodiments, the heat-conducting element 321 and the reflector 330 are arranged in a non-contact manner, resulting in a certain structural gap between them. This ensures that the heat absorbed by the heat-conducting element 321 can only be transferred to the reflector 330 in the form of thermal radiation, while the reflector 330 can also reflect heat back to the heat-conducting element 321. Based on this, heat loss due to thermal radiation can be effectively reduced, allowing the heat generated by the heating element 322 to be maximized for the aerosol generation matrix A, thus improving heat utilization efficiency.

[0045] In some embodiments, the surface of the reflector 330 facing the heat conduction element 321 (which can also be understood as the inner surface of the reflector 330) is a smooth surface structure. The mirror reflection of the smooth surface structure can effectively improve the heat reflection performance of the reflector 330, thereby reflecting more of the heat radiated by the heat conduction element 321 and / or the heat generation element 322 back, so as to reduce the heat loss at the reflector 330.

[0046] Of course, in other embodiments, the reflector 330 may also include a reflective film or reflective layer disposed toward the heat-conducting element 321. Both the reflective film and the reflective layer may be made of a material with high reflectivity. For example, the reflective layer may be formed by coating the inner surface with a material with high reflectivity.

[0047] Please see Figure 4 In some embodiments, the heating element 322 includes a heat transfer portion 3221 and a heating portion 3222. The heating portion 3222 and the support protrusion 3213 are disposed opposite to each other on two sides of the heat transfer portion 3221. At least a portion of the structure of the heat transfer portion 3221 is connected to the heat conductor 321, thereby increasing the contact area and improving the heat transfer efficiency to enhance the heat utilization rate.

[0048] In some embodiments, the heating element 3222 is a heating area, heating film, or heating circuit 3223 disposed on the heat transfer element 3221, such as Figure 4 As shown, the heating element 3222 is a heating line 3223 provided on the heat transfer element 3221. In order to reduce the heat at the end of the aerosol generation matrix A, the heating element 3222 is provided on the side of the heat transfer element 3221 away from the heating chamber 323.

[0049] In some embodiments, the heating area, heating film, or heating circuit 3223 is made of resistive material and can be fixed to the heat transfer part 3221 by coating, embedding, or bonding.

[0050] In some embodiments, the heat-conducting element 321 and the heat-generating element 322 are constructed as an integral structure, which can simplify the assembly process, improve assembly efficiency, and effectively ensure the contact between the heat-conducting element 321 and the heat-generating element 322 and improve the heat conduction efficiency.

[0051] In some embodiments, the reflector 330 extends along the axial direction of the heat conductor 321, and one end away from the air outlet 311 abuts against a portion of the structure of the heating element 322. The reflector 330 can reflect the heat radiated outward by the heat conductor 321 in the opposite direction, so that the heat acts on the air or aerosol in the heating chamber 323 after passing through the heat conductor 321 to generate matrix A.

[0052] In other embodiments, please refer to Figure 5The reflector 330 includes a first reflector 331 and a second reflector 332. The first reflector 331 is coaxially disposed with the heat-conducting element 321 and surrounds the outside of the heat-conducting element 321. The second reflector 332 is connected to the first reflector 331 and is disposed outside the heat-generating element 322. The first reflector 331 reflects the heat radiated outward from the heat-conducting element 321, and the second reflector 332 reflects the heat radiated outward from the heat-generating element 322. The arrangement of the first reflector 331 and the second reflector 332 can improve the heat reflection efficiency, thereby reducing heat loss.

[0053] Please see Figure 6 In some embodiments, the airflow channel 324 includes a first ventilation section 3241 and a second ventilation section 3242, which are connected. The first ventilation section 3241 is formed on the inner wall of the heat-conducting element 321, and the second ventilation section 3242 is formed between the heating element 322 and the aerosol generating matrix A. When the outside air flows through the first ventilation section 3241, it is heated to form a hot airflow, which then enters the inner wall of the aerosol generating matrix A through the second ventilation section 3242 for airflow heating. The setting of the second air inlet section can form a buffer space for the hot airflow, thereby effectively ensuring the continuous generation of aerosol.

[0054] Please see Figure 7In some embodiments, the inner wall of the heat-conducting element 321 is provided with a plurality of recesses 3211, which are evenly and spaced around the center of the heat-conducting element 321 to form a first ventilation section 3241. A protrusion 3212 is formed between adjacent recesses 3211. The protrusion 3212 can abut against the outer wall surface of the aerosol generating matrix A to achieve clamping and fixing of the aerosol generating matrix A. Since the protrusion 3212 is also evenly arranged, it is also convenient to center (or coaxial with the heating chamber 323) the aerosol generating matrix A, so that the airflow around the aerosol generating matrix A is uniform, so as to achieve uniform heating of the aerosol generating matrix A. The inner wall of the heat-conducting element 321 or the heating element 322 is provided with a supporting protrusion 3213, which is used to abut against the end of the aerosol generating matrix A to form a second ventilation section 3242 between the heating element 322 and the aerosol generating matrix A. The formation of the second ventilation section 3242 also allows the end of the aerosol generating matrix A to be moved away from the heat source (i.e., the heat-generating element 322), thereby preventing the end of the aerosol generating matrix A from generating impurities due to excessive temperature, which would affect the taste of the aerosol. The number of support protrusions 3213 may include one or more. When there is one or more support protrusions 3213, the support protrusions 3213 are also spaced apart, so that a gap is formed between two adjacent support protrusions 3213 to allow airflow to pass through. This gap connects the first ventilation section 3241 and the second ventilation section 3242. In order to make the airflow uniform, the support protrusions 3213 are also uniformly arranged around the center of the mounting cavity 323.

[0055] Please see Figure 3 and Figure 8 The support assembly 310 includes a support cylinder 312, a base 313, and a cover 314. The base 313 and the cover 314 are respectively disposed at both ends of the support cylinder 312. The air inlet is formed on the side of the cover 314 away from the support cylinder 312. The support cylinder 312 has a first snap-fit ​​protrusion 3121 inside, which extends toward the center of the support cylinder 312. The heat-conducting element 321 has a second snap-fit ​​protrusion 3214 on its outer wall, which extends away from the center of the support cylinder 312. The second snap-fit ​​protrusion 3214 is clamped between the first snap-fit ​​protrusion 3121 and the cover 314 to fix the heating assembly 320. The reflector 330 is also clamped and fixed between the first snap-fit ​​protrusion 3121 and the side wall of the heat-conducting element 321. The heating assembly 320 and the base 313 are spaced apart. The connection between the heating component 320 and the support component 310 is achieved through the first snap-fit ​​protrusion 3121, the second snap-fit ​​protrusion 3214, and the cover 314. This reduces the contact area between the heating component 320 and the support component 310, thereby reducing heat loss due to contact. Similarly, the spacing between the heating component 320 and the base 313 also avoids heat loss due to contact, thus improving the heat utilization rate of the atomizing device.

[0056] In some embodiments, in order to further reduce heat loss, the support component 310 is made of a material with low thermal conductivity and high temperature resistance, such as polyetheretherketone (PEEK). This can reduce heat loss at the support component 310 and prevent the support component 310 from failing due to high temperature, thus affecting the service life of the atomizing device.

[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.
