An atomizing channel is formed in the atomizing core support. The atomizing core support is inserted into the second liquid guiding component. The atomizing core is disposed in the atomizing channel.

[0011] In some examples, the atomizing core structure includes a liquid guiding layer, a portion of which is wrapped around the heating element to form the fourth liquid guiding element, and another portion of which is wrapped around the atomizing core support to form the third liquid guiding element.

[0012] In some examples, the liquid guiding layer is wrapped around the atomizing core support at least once.

[0013] In some examples, a slit is provided on the sidewall of the second liquid guide, the slit extending axially along the second liquid guide and penetrating the inner and outer sides of the second liquid guide; the third liquid guide is located between the two ends of the slit in the axial direction of the second liquid guide.

[0014] In some examples, the atomizing core structure further includes a support tube inserted into the second liquid guiding component, one end of which is connected to the atomizing core support, and the support tube is interference-fitted with the second liquid guiding component.

[0015] In some examples, the distance from the atomizing core to the inlet end of the atomizing channel is not less than 20% of the length of the first through hole.

[0018] Secondly, embodiments of this application also provide an atomizer, the atomizer including a liquid storage component and any of the atomizing components described in the first aspect; the atomizing component is disposed in the liquid storage component.

[0019] In some examples, the liquid storage assembly includes a liquid storage housing, a first seal, and a second seal. The liquid storage housing has two opposite ends, and the atomizing assembly is located in the liquid storage housing.

Since the density of the second liquid guiding component is greater than that of the first liquid guiding component, the capillary force generated by the second liquid guiding component is stronger, and the aerosol generating matrix in the first liquid guiding component can be siphoned by the second liquid guiding component, which can promote the flow of the aerosol generating matrix in the first liquid guiding component to the atomizing core structure and reduce the residue of the aerosol generating matrix in the atomizer.

[0031] Figure 1 is a schematic diagram of an atomizing component according to an embodiment of this application. As shown in Figure 1, the atomizing component 22 includes a first liquid guiding element 221, a second liquid guiding element 222, and an atomizing core structure 223. The first liquid guiding element 221 and the second liquid guiding element 222 are used to adsorb / wet the aerosol generation matrix. The second liquid guiding element 222 is tubular, and the atomizing core structure 223 is inserted into the second liquid guiding element 222. The first liquid guiding element 221 has a first through hole 221a, and the second liquid guiding element 222 is inserted into the first through hole 221a. The density of the second liquid guiding element 222 is greater than the density of the first liquid guiding element 221.

[0032] By placing the atomizing core structure 223 in the second liquid guiding element 222 and inserting the second liquid guiding element 222 into the first through hole 221a of the first liquid guiding element 221, when using the atomizing assembly 22, the aerosol generating matrix can be absorbed by the first liquid guiding element 221 and then seep into the second liquid guiding element 222, which then supplies the atomizing core structure 223. Since the density of the second liquid guiding element 222 is greater than that of the first liquid guiding element 221, the capillary force generated by the second liquid guiding element 222 is stronger. The aerosol generating matrix in the first liquid guiding element 221 can be siphoned by the second liquid guiding element 222, which can promote the flow of the aerosol generating matrix in the first liquid guiding element 221 to the atomizing core structure 223, reducing the residual aerosol generating matrix in the atomizer 2.

[0033] For example, the materials of the first liquid guiding component 221 and the second liquid guiding component 222 may respectively include one or more of organic cotton, synthetic fibers, polymer PE / PC, ceramics, flax, and non-woven fabric.

[0034] The first liquid guiding component 221 and the second liquid guiding component 222 can be porous structures, which are beneficial for adsorbing and storing aerosols to form a matrix.

[0035] The porosity of the second liquid guiding element 222 can be less than that of the first liquid guiding element 221, so that the density of the second liquid guiding element 222 is greater and it can generate stronger capillary force, causing the aerosol generation matrix in the second liquid guiding element 222 to flow to the first liquid guiding element 221.

[0036] The density of the second liquid guiding component 222 is greater than that of the first liquid guiding component 221, which also makes the hardness of the second liquid guiding component 222 higher than that of the first liquid guiding component 221. This makes it easier to assemble the second liquid guiding component 222 into the first through hole 221a when assembling the atomizing component 22.

[0037] In some examples, the density ratio of the second liquid guiding element 222 to the density of the first liquid guiding element 221 is not less than 1.1. That is, the density of the second liquid guiding element 222 is 10% or more greater than the density of the first liquid guiding element 221.

[0038] By making the second liquid guiding element 222 and the first liquid guiding element 221 have a sufficiently large density difference, the second liquid guiding element 222 can generate a sufficiently large capillary force to cause the aerosol generating matrix in the first liquid guiding element 221 to flow to the second liquid guiding element 222.

[0039] For example, the density of the first liquid guiding element 221 can be 0.06 g / cm³. 3 0.07 g / cm 3 0.08 g / cm 3 0.09g / cm 3 0.1 g / cm 3 The density of the second liquid guiding component 222 can be 0.07 g / cm³. 3 0.08 g / cm 3 0.08 g / cm 3 0.1g / cm 3 0.11 g / cm 3 0.12 g / cm 3 0.13 g / cm 3 .

[0040] The first liquid guiding element 221 may be columnar, and the first through hole 221a extends through both ends of the first liquid guiding element 221 along the axial direction of the first liquid guiding element 221.

[0041] As an example, the first liquid guiding element 221 can be a cylindrical structure. The second liquid guiding element 222 can be a circular tube, that is, the cross-section of the second liquid guiding element 222 can be circular. The first through hole 221a can be arranged coaxially with the first liquid guiding element 221. This facilitates the uniform flow of the aerosol generating matrix from all directions of the first through hole 221a to the second liquid guiding element 222.

[0042] The thickness of the second liquid guiding member 222 can be less than the thickness of the first liquid guiding member 221. In this embodiment, the thickness of the second liquid guiding member 222 refers to the distance between the inner and outer sidewalls of the second liquid guiding member 222 along the radial direction of the second liquid guiding member 222; the thickness of the first liquid guiding member 221 refers to the distance between the inner and outer sidewalls of the first liquid guiding member 221 along the radial direction of the first liquid guiding member 221.

[0043] In some examples, at least one end of the second liquid guide 222 and the first liquid guide 221 are flush.

[0044] As an example, as shown in Figure 1, both ends of the first liquid guide 221 and the second liquid guide 222 are flush.

[0045] Due to gravity, the aerosol-generating matrix within the first liquid guiding component 221 tends to accumulate at one end, leading to oversaturation in certain areas and potential leakage from the wall of the first through-hole 221a. By aligning the end of the second liquid guiding component 222 with the end of the first liquid guiding component 221, the entire wall of the first through-hole 221a is in contact with the second liquid guiding component 222. This allows the aerosol-generating matrix leaking from the wall of the first through-hole 221a to be absorbed by the second liquid guiding component 222, thus reducing the risk of leakage from the first liquid guiding component 221.

[0046] In some examples, the second liquid guide 222 may be interference-fitted with the first liquid guide 221.

[0047] Using an interference fit can reduce the gap between the first liquid guiding element 221 and the second liquid guiding element 222, thereby reducing the risk of leakage of the aerosol generating matrix from the gap between the two liquid guiding elements 221 and 222. The interference fit also ensures good contact between the second liquid guiding element 222 and the wall of the first through hole 221a, allowing the aerosol generating matrix in the first liquid guiding element 221 to flow more effectively to the second liquid guiding element 222 under the capillary force provided by the second liquid guiding element 222, preventing the aerosol generating matrix from becoming interrupted and affecting the normal operation of the atomizing core structure 223.

[0048] The second liquid guide 222 and the atomizing core structure 223 can also be interference-fitted, which can reduce the risk of aerosol generation matrix leaking from the gap between the second liquid guide 222 and the atomizing core structure 223, and can also make the atomizing core structure 223 more stable to install.

[0049] Figure 2 is a schematic diagram of an atomizing core structure according to an embodiment of this application. As shown in Figure 2, the atomizing core structure 223 may include an atomizing core support 3, an atomizing core 4, and a third liquid guiding member 5. An atomizing channel 3a is formed in the atomizing core support 3, and the atomizing core support 3 is inserted into the second liquid guiding member 222. The atomizing core 4 is disposed in the atomizing channel 3a. The third liquid guiding member 5 is disposed outside the atomizing core support 3 and is connected to the atomizing core 4.

[0050] Figure 3 is a schematic diagram of the internal structure of an atomizing component provided in an embodiment of this application. As shown in Figure 3, the atomizing core support 3 is inserted into the second liquid guide 222, which supports the second liquid guide 222 and prevents it from collapsing inward. By placing the third liquid guide 5 outside the atomizing core support 3 and connecting the third liquid guide 5 to the atomizing core 4, the aerosol generating matrix can flow to the atomizing core 4 under the action of the third liquid guide 5. Especially when the remaining aerosol generating matrix in the atomizer 2 is small, the third liquid guide 5 can promote the flow of the remaining aerosol generating matrix in the first liquid guide 221 and the second liquid guide 222 to the atomizing core 4, thereby further reducing the residue of the aerosol generating matrix.

[0051] The atomizing channel 3a has an inlet end and an outlet end, and the distance from the atomizing core 4 to the inlet end of the atomizing channel 3a is not less than 20% of the length of the first through hole 221a.

[0052] Under the influence of gravity, the aerosol generating matrix within the first liquid guiding component 221 tends to accumulate towards the end of the first liquid guiding component 221 near the inlet of the atomization channel 3a, leading to oversaturation of the aerosol generating matrix and high pressure in a localized area. By increasing the distance from the atomizing core 4 to the inlet of the atomization channel 3a, oversaturation of the aerosol generating matrix near the atomizing core 4 can be avoided, reducing the risk of leakage of the aerosol generating matrix from the atomizing core 4.

[0053] For example, the distance from the atomizing core 4 to the inlet end of the atomizing channel 3a can be 25%, 30%, 35%, 40%, 45%, 50%, 55%, or 60% of the length of the first through hole 221a.

[0054] As shown in Figure 3, the atomizing core 4 may include a fourth liquid guiding element 42 and a heating element 41. The fourth liquid guiding element 42 is provided with a second through hole 42a, and the heating element 41 is located in the second through hole 42a. The fourth liquid guiding element 42 is connected to the third liquid guiding element 5.

[0055] The heating element 41 is used to heat the aerosol generating matrix in the fourth liquid guiding element 42, causing the aerosol generating matrix to vaporize. The material and structure of the heating element 41 are not limited, as long as it can perform the heating function. For example, the heating element 41 may include at least one of the following: heating mesh, heating film, heating wire, and heating plate.

[0056] The heating element 41 may include one or more heating meshes. For example, as shown in Figure 2, the heating element 41 includes two heating meshes.

[0057] For example, the material of the heating element 41 can be any one of nickel, nickel alloy, titanium, titanium alloy, and stainless steel.

[0058] Nickel, nickel alloys, titanium, titanium alloys, and stainless steel are stable, not easily oxidized, corrosion-resistant, and can withstand high temperatures for a long time, resulting in a long service life.

[0059] For example, the nickel alloy may include nickel 50 and nickel-chromium-aluminum alloy.

[0060] The aerosol generating matrix in the third liquid guiding component 5 can flow to the fourth liquid guiding component 42 connected to the third liquid guiding component 5. The heating element 41 is disposed in the second through hole 42a, and the aerosol generating matrix in the fourth liquid guiding component 42 can adhere to the heating element 41 and be heated and atomized by the heating element 41 to form an aerosol.

[0061] The atomizing core structure 223 may also include a lead wire 7, one end of which can be connected to the heating element 41, and the other end of which can extend outside the atomizing channel 3a. For example, the lead wire 7 can extend from the inlet end of the atomizing channel 3a. The lead wire 7 is used for electrical connection with the power supply component 1.

[0062] Multiple leads 7 can be provided, for example, two or three. Each heating element is connected to two leads 7, thereby allowing different heating elements to be controlled to operate.

[0063] The surface of the lead 7 may be provided with an insulating coating to prevent different leads 7 from directly contacting each other and forming a short circuit.

[0064] In some examples, lead 7 may be made of one of the following: nickel, silver, nickel alloy, silver alloy, nickel-plated copper composite, or copper-plated nickel composite.

[0065] The lead wire 7, made of the above materials, has good electrical conductivity, suitable for current transmission requirements. It also possesses a certain degree of corrosion resistance, resisting oxidation and chemical corrosion to a certain extent, maintaining the stable performance of the lead wire 7. It has good mechanical properties, able to withstand a certain degree of tension and bending, suitable for applications requiring high mechanical strength. Furthermore, it exhibits stable electrical properties within a certain temperature range, ensuring that the electrical characteristics of the lead wire 7 are unaffected by the external environment, which is beneficial for precise temperature control of the heating element 41.

[0066] As an example, the heating element 41 can be made of a material with TCR (Temperature Coefficient of Resistance) properties. For example, the heating element 41 can be made of a PTC (Positive Temperature Coefficient) material.

[0067] During the operation of the heating element, the temperature of the heating element 41 can be determined based on its resistance and the temperature coefficient of resistance, thus allowing for accurate temperature control. The specific process for controlling the temperature of the heating element 41 can be found in relevant technical specifications.

[0068] In some possible implementations, the atomizer core structure 223 may also include a temperature sensing element, which may be disposed on the atomizer core support 3 and in contact with or spaced from the heating element 41. The temperature sensing element is used to detect the temperature of the heating element 41. The temperature sensing element may be, for example, a thermocouple.

[0069] Multiple temperature measuring elements can be set, and each temperature measuring element can be set one-to-one with the heating grid of the heating element 41. One temperature measuring element is set near each heating grid to facilitate accurate measurement of the temperature of each heating grid.

[0070] The atomizing core structure 223 may also include a support ring 8, which can be snapped into the atomizing core bracket 3. The support ring 8 can be located at the inlet end of the atomization channel 3a, and the lead wire 7 can be clamped between the outer wall of the support ring 8 and the inner wall of the atomizing core bracket 3, thereby fixing the lead wire 7 through the support ring 8.

[0071] For example, a limiting groove 8a may be provided on the outer wall of the support ring 8, and the lead wire 7 may be located in the limiting groove 8a.

[0072] In some examples, the atomizing core structure 223 may also include a support tube 6, one end of which is connected to the atomizing core support 3. The support tube 6 is inserted into the second liquid guide 222, and the support tube 6 and the second liquid guide 222 are interference-fitted. The support tube 6 may be connected to the outlet end of the atomizing channel 3a.

[0073] The support tube 6 and the atomizer core bracket 3 together support the second liquid guide 222, preventing the second liquid guide 222 from collapsing inward. The support tube 6 reduces the length of the atomizer core bracket 3, and the shorter atomizer core bracket 3 makes it easier to assemble the atomizer core 4 into the atomizer core bracket 3.

[0074] When assembling the atomizing core structure 223, the atomizing core 4 can be inserted into one end of the atomizing core bracket 3, and then the support tube 6 can be connected to the same end of the atomizing core bracket 3. For example, the support tube 6 can be sleeved with the atomizing core bracket 3; for instance, the end of the atomizing core bracket 3 that accommodates the atomizing core 4 can be sleeved outside the support tube 6.

[0075] In some examples, the materials of the atomizer core holder 3 and the support tube 6 can be the same, for example, both can be made of glass fiber, which is not easily deformed, can withstand certain high temperatures, and is lightweight and durable.

[0076] As shown in Figure 2, the position on the atomizing core support 3 covered by the third liquid guiding component 5 may have a first opening 3b, and the outer surface of the atomizing core 4 is positioned opposite to the first opening 3b.

[0077] By setting up structures such as holes and gaps, for example, the first opening 3b, and using the third liquid guiding element 5 to cover the first opening 3b, the aerosol generation matrix in the third liquid guiding element 5 can flow to the atomizing core 4 not only from the connection between the third liquid guiding element 5 and the atomizing core 4, but also from the first opening 3b. This helps to increase the liquid supply to the atomizing core 4, better adapt to the atomizing core 4 with higher power, and improve the mist production of the atomizer 2.

[0078] For example, multiple first openings 3b can be provided, and the multiple first openings 3b can be distributed at intervals along the length direction and / or circumferential direction of the atomizing core support 3 to further increase the liquid supply to the atomizing core 4.

[0079] The atomizing core support 3 may also be provided with a second opening 3c, which can extend to the end face of the atomizing core support 3 near the support tube 6 to facilitate the installation of the atomizing core 4 and the third liquid guide 5. The connection between the third liquid guide 5 and the fourth liquid guide 42 can be located in the second opening 3c.

[0080] Figure 4 is a schematic diagram of an atomizing core structure provided in an embodiment of this application. As shown in Figure 4, as an example, the atomizing core structure 223 may include a liquid guiding layer 40. A part of the liquid guiding layer 40 is wrapped around the heating element 41 to form a fourth liquid guiding element 42, and another part of the liquid guiding layer 40 is wrapped around the atomizing core support 3 to form a third liquid guiding element 5.

[0081] By wrapping the liquid guiding layer 40 around the heating element 41 and the atomizing core support 3 respectively, a connected fourth liquid guiding element 42 and third liquid guiding element 5 are formed, so that the aerosol generation matrix can flow along the liquid guiding layer 40 into the interior of the atomizing core support 3.

[0082] The third liquid guide 5 is formed by winding, which can firmly fix the third liquid guide 5 on the atomizing core bracket 3, and can also provide a certain restriction on the heating element 41, so that the heating element 41 is installed stably in the atomizing channel 3a.

[0083] The liquid guiding layer 40 can be wrapped around the atomizing core support 3 for less than one turn, or it can be wrapped around one turn or more.

[0084] As an example, the liquid guiding layer 40 can be wrapped around the atomizing core support 3 at least once, so that the formed third liquid guiding element 5 is a 360° ring around the atomizing core support 3. The aerosol generating matrix flowing from all directions in the second liquid guiding element 222 to the third liquid guiding element 5 can be absorbed by the third liquid guiding element 5, which can increase the liquid supply to the atomizing core 4 and stabilize the supply of aerosol generating matrix, avoiding the interruption of the supply of aerosol generating matrix that would cause the heating element 41 to burn dry.

[0085] For example, the liquid guiding layer 40 is wound around the atomizing core support 3 in a range greater than 360° and less than 720°, that is, the liquid guiding layer 40 is wound around the atomizing core support 3 for more than one turn but less than two turns. Wrapping for more than one turn allows the liquid guiding layer 40 to be better wrapped tightly on the outer wall of the atomizing core support 3, while wrapping for less than two turns can prevent the thickness of the formed third liquid guiding element 5 in the radial direction of the atomizing core support 3 from being too large, which would cause a gap to form between the atomizing core support 3 and the second liquid guiding element 222, affecting the flow of the aerosol generation matrix into the atomizing core support 3.

[0086] When manufacturing the atomizing component 22, a portion of the liquid guiding layer 40 can be first wrapped around the heating element 41 to form a fourth liquid guiding element 42, thus obtaining the atomizing core 4; then the atomizing core 4 can be installed into the atomizing core support 3, allowing another portion of the liquid guiding layer 40 to extend out of the atomizing core support 3 through the second opening 3c; then the liquid guiding layer 40 can be wrapped around the atomizing core support 3 to form a third liquid guiding element 5, thus obtaining the atomizing core structure 223; finally, the atomizing core structure 223 can be installed into the second liquid guiding element 222.

[0087] Since the third liquid guiding element 5 is located on the outer wall of the atomizing core support 3, it is inconvenient to install the atomizing core structure 223 into the second liquid guiding element 222. To facilitate the assembly of the atomizing assembly 22, as shown in Figure 3, a slit 222a can be provided on the side wall of the second liquid guiding element 222. The slit 222a extends along the axial direction of the second liquid guiding element 222 and penetrates both the inner and outer sides of the second liquid guiding element 222. In the axial direction of the second liquid guiding element 222, the third liquid guiding element 5 is located between the two ends of the slit 222a, that is, the length range occupied by the third liquid guiding element 5 in the axial direction of the second liquid guiding element 222 is within the length range occupied by the slit 222a in the axial direction of the second liquid guiding element 222.

[0088] For example, Figure 5 is a second schematic diagram of an atomizing component provided in an embodiment of this application. At least the first liquid guide 221 is omitted in Figure 5. A coordinate system is established in Figure 5, with its X-axis overlapping the axis of the second liquid guide 222. The origin of the coordinate system is located at one end of the second liquid guide 222, and the direction from the origin to the other end of the second liquid guide 222 is the positive direction of the X-axis. The length range occupied by the slit 222a along the axial direction of the second liquid guide 222 can be represented as the interval [0, c]. The length range occupied by the third liquid guide 5 along the axial direction of the second liquid guide 222 can be represented as the interval [a, b], where 0 < a < b ≤ c, and a, b, and c are all positive numbers. [a, b] is contained within [0, c], meaning that the length range occupied by the third liquid guide 5 along the axial direction of the second liquid guide 222 is within the length range occupied by the slit 222a along the axial direction of the second liquid guide 222.

[0089] During the assembly of the atomizing component 22, the atomizing core 4 is inserted into the atomizing core support 3, and a portion of the liquid guiding layer 40 extends out of the atomizing core support 3 through the second opening 3c; then the atomizing core support 3 is inserted into the second liquid guiding member 222, so that the liquid guiding layer 40 is inserted into the slit 222a relative to the portion of the atomizing core support 3 extending from the second opening 3c; by rotating the atomizing core support 3 and the second liquid guiding member 222 relative to each other, during the rotation, the liquid guiding layer 40 gradually flows from the slit 222a into the second liquid guiding member 222, and wraps around the atomizing core support 3 to form the third liquid guiding member 5.

[0090] The slit 222a allows the atomizing core support 3 to be inserted into the second liquid guide 222 between the formation of the third liquid guide 5, which facilitates the assembly of the atomizing assembly 22.

[0091] In this example, axially, one end of the slit 222a is located at the end of the second liquid guide 222 near the inlet end of the atomizing channel 3a. In other possible implementations, one end of the slit 222a may also be located at the end of the second liquid guide 222 away from the inlet end of the atomizing channel 3a, as long as the liquid guide layer 40 can pass through the slit 222a.

[0092] Figure 6 is a schematic diagram of an aerosol generating device provided in an embodiment of this application. The aerosol generating device refers to a device that can heat an aerosol generating matrix to a certain temperature, causing the corresponding components in the aerosol generating matrix to atomize and form an inhalable aerosol. Inhalation refers to the state of being inhaled into the user's oral cavity, nasal cavity, or lungs through the user's mouth or nose. The aerosol generating matrix refers to a product capable of forming an aerosol under heating. Aerosols may contain volatile compounds. The aerosol generating matrix can be liquid or semi-liquid.

[0093] As shown in Figure 6, the aerosol generating device includes a power supply component 1 and an atomizer 2. The power supply component 1 is used to supply power to the atomizer core 3.

[0094] Figure 7 is a schematic diagram of an atomizer provided in an embodiment of this application. As shown in Figure 7, the atomizer 2 may include a liquid storage component 21 and any of the aforementioned atomizing components 22. The atomizing component 22 is disposed in the liquid storage component 21.

[0095] By applying the aforementioned atomizing component 22 to the atomizer 2, since the density of the second liquid guiding element 222 in the atomizing component 22 is greater than the density of the first liquid guiding element 221, the capillary force generated by the second liquid guiding element 222 is stronger. The aerosol generating matrix in the first liquid guiding element 221 can be siphoned by the second liquid guiding element 222, which can promote the flow of the aerosol generating matrix in the first liquid guiding element 221 to the atomizing core structure 223 and reduce the residue of the aerosol generating matrix in the atomizer 2.

[0096] As an example, the liquid storage assembly 21 may include a liquid storage housing 211, a first seal 212, and a second seal 213. The liquid storage housing 211 has two opposing ends, and the atomizing assembly 22 is located within the liquid storage housing 211. The first seal 212 is connected to one end of the liquid storage housing 211, and the second seal 213 is connected to the other end of the liquid storage housing 211.

[0097] Both the first seal 212 and the second seal 213 have through holes communicating with the atomizing core structure 223. The through hole on the first seal 212 is used for air intake, and the through hole on the second seal 213 is used for aerosol discharge. The atomizing core structure 223 can be connected to the through hole on the first seal 212. For example, the end of the atomizing core holder 3 away from the support tube 6 can extend out of the second liquid guide 222 and be inserted into the through hole of the first seal 212, and the support ring 8 can also be located in the through hole of the first seal 212. The atomizing core holder 3 and the through hole of the first seal 212 can be interference-fitted to improve sealing and reduce the risk of leakage.

[0098] The first seal 212 and the second seal 213 cooperate with the liquid storage tank housing 211 to form a sealed liquid storage tank to accommodate the atomizing assembly 22, preventing the leakage of the aerosol matrix adsorbed by the first liquid guide 221 and the second liquid guide 222.

[0099] For example, the first seal 212 and the second seal 213 may be silicone or rubber components.

[0100] The inner wall of the liquid storage tank shell 211 can contact the outer wall of the first liquid guiding component 221, so that almost all the aerosol generating matrix in the liquid storage tank is in an absorbed state and stored in the first liquid guiding component 221, which helps to avoid leakage of the aerosol generating matrix.

[0101] Referring to Figure 6, the aerosol generating device may further include a housing 91 and a base 93. The housing 91 is fitted over the atomizer 2 and the power supply assembly 1. The power supply assembly 1 may be connected to the first sealing member 212, and the base 93 is connected to the end of the power supply assembly 1 away from the first sealing member 212. The housing 91 covers the atomizer 2 and the power supply assembly 1, and the end of the housing 91 away from the base 93 may be provided with a mouthpiece 92, which communicates with a through hole on the second sealing member 213. The housing 91 may also be connected to the base 93. The housing 91 and the base 93 may be detachably connected to facilitate the replacement of the power supply assembly 1 or the atomizer 2.

[0102] There may be a gap between the outer wall of the liquid storage tank shell 211 and the inner wall of the outer shell 91. The outer shell 91 may be provided with an air inlet 91a, which communicates with the through hole on the first seal 212 through the gap. When the user performs suction, air from the outside environment can enter the outer shell 91 through the air inlet 91a; then flow through the gap between the outer wall of the liquid storage tank shell 211 and the inner wall of the outer shell 91 to the through hole of the first seal 212, and then enter the atomization channel 3a through the through hole of the first seal 212; the gas discharged from the atomization channel 3a reaches the nozzle 92 through the through hole of the second seal 213, and finally the aerosol is discharged from the nozzle 92.

[0103] For example, the air inlet 91a can be located at the end of the housing 91 near the nozzle 92, that is, the air inlet 91a is located away from the first seal 212 and close to the second seal 213. In this way, even if the aerosol generating matrix or condensate leaks from the through hole of the first seal 212 during the use of the aerosol generating device, it is difficult to reach the air inlet 91a, thereby reducing the risk of liquid leakage to the outside of the aerosol generating device and improving the user experience.

[0104] As shown in Figure 6, the power supply component 1 may include a power source 11. Exemplarily, the power source 11 may be a DC power source, such as a battery. Specifically, it may include a lithium-ion battery, a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery. The lithium-based battery may include a lithium cobalt battery, a lithium iron phosphate battery, a lithium titanate battery, or a lithium polymer battery.

[0105] The power supply component 1 may also include a circuit structure, which may include a circuit board electrically connected to the power supply 11. The circuit board is used to control the operation of the aerosol generating device. The lead 7 of the atomizer 2 may be electrically connected to the circuit board.

[0106] In some examples, a button 12 may be provided on the circuit board for controlling the aerosol generating device. For example, button 12 is used to control the atomizer 2 to be powered on or off.

[0107] A keycap 911 can be installed on the outer casing 91, and the keycap 911 is connected to the button 12.

[0108] The power supply assembly 1 may further include a connector 13, with a circuit board located between the connector 13 and the power supply 11. The connector 13 may be connected to the base 93. An electrode 131 may be provided on the connector 13 for electrical connection to the lead 7 of the atomizer 2. The connector 13 may be connected to the housing 91. Exemplarily, the connector 13 may be connected to the housing 91 via a snap-fit ​​connection.

[0109] The circuit structure may also include one or more controllers for controlling the operation of the heating element 41. The controllers may be mounted on a circuit board.

[0110] For example, the controller may include at least one of the following: MCU (Micro Controller Unit), CPU (Central Processing Unit), FPGA (Field Programmable Gate Array), and analog circuit.

[0111] Taking a controller including an MCU and a heating element 41 made of a material with TCR characteristics as an example, during the operation of the heating non-combustible device, the MCU's ADC (Analog to Digital Converter) function can be used for real-time sampling. The sampled data may include, for example, the voltage across the heating element 41. The real-time resistance value of the heating element 41 is then calculated based on the sampled data, and the temperature of the heating element 41 can be determined by combining this with its temperature coefficient of resistance. This is only one example; the specific process of determining the temperature of the heating element 41 based on its resistance and temperature coefficient of resistance during operation can be found in relevant technologies.

[0112] The controller can be used to control the heating element 41 to heat at a desired temperature. For example, the controller can proportionally... integral Differential (Proportional) Integral Derivative (PID) control is used to regulate the temperature and ensure that the temperature of the heating element 41 is stable at the required temperature.

[0113] The controller can also be used to control the heating method of the heating element 41, for example, by changing the way multiple leads 7 are connected to the power supply component 1, so that different heating grids can be heated, thereby changing the temperature distribution in the atomization channel 3a and producing different heating effects.

[0114] The controller's control of the heating element 41 can be based on a pre-set computer program. The circuit structure may also include a computer-readable storage medium for storing the computer program. This computer-readable storage medium may include: computer memory, read-only memory (ROM), etc. Only memory (ROM), random access memory (RAM), electrical carrier signals, telecommunication signals, and software distribution media.

[0115] Connectors, such as charging connectors and Universal Serial Bus (USB) connectors, can also be attached to the circuit board. These connectors may be partially exposed outside the housing 91 to facilitate connection to other devices. In some examples, the charging connector and the USB connector may be the same connector.

[0116] By setting up a Universal Serial Bus connector, it can be used not only to charge the power supply 11, but also to update computer programs stored on readable storage media.

[0117] In some examples, the circuit structure may also include a wireless communication module, which may include at least one of the following: Bluetooth module, Bluetooth Low Energy (BLE) module, Zigbee module, Low Power WIFI module, Near Field Communication (NFC) module, and infrared module.

[0118] By incorporating a wireless communication module, computer programs stored on readable storage media can be easily updated wirelessly, and interaction with other devices can be achieved. For example, interaction with mobile phones, tablets, laptops, dashcams, in-vehicle computers, and another heated non-combustible device.

[0119] In some examples, the circuit structure may also include a display panel that is electrically connected to the circuit board. At least a portion of the housing 91 may be a light-transmitting area, and the display panel may be positioned facing the light-transmitting area so that the user can observe the content displayed on the display panel.

[0120] For example, the display panel can be located in the gap between the housing 91 and the liquid reservoir housing 211. The light-transmitting area can be a transparent portion of the housing 91 or an opening on the surface of the housing 91 exposing the display panel. The display panel can be a liquid crystal display (LCD) panel or an organic light-emitting diode (OLED) display panel. The display panel can be a display panel with only display function, or a touch display panel with touch function in addition to display function, to facilitate user operation.
