Atomizing components, heating elements, and aerosol generating devices
[0001] Cross-reference to related applications
[0002] This application claims priority to Chinese Patent Application No. 202411632826.X, filed on November 14, 2024, entitled “Atomizing Component, Heating Element and Aerosol Generating Device”, the entire contents of which are incorporated herein by reference. Technical Field
[0003] This application relates to the technical field of aerosol generating devices, and particularly to an atomizing component and an aerosol generating device, as well as a heating element used in an aerosol generating device. Background Technology
[0004] With continuous technological advancements, the design and manufacturing techniques of aerosol generation devices have become increasingly sophisticated. Among numerous technological innovations, the thickness of heating elements has been gradually reduced to achieve higher thermal efficiency and ease of use. However, this thinner heating element has also brought about some problems during application. Specifically, the liquid guiding element expands after absorbing the liquid matrix. This inward expansion compresses the space of the inner airway, thus affecting the user's inhalation experience. On the other hand, the expansion of the liquid guiding element can also compress the heating element inward. This compression can cause deformation of the heating element, affecting its normal operating performance. For example, it can alter the fit between the heating element and the liquid guiding element, reducing the overall performance of the aerosol generation device and the user experience.
[0005] Application content
[0006] To solve the above technical problems, this application provides an atomizing component, a heating element, and an aerosol generating device.

[0013] As one embodiment of the atomizing component, the extension length of the first support is substantially equal to the distance between the first pin and the second pin, and there is a longitudinal gap between the first support and the second pin.
[0014] As one embodiment of the atomizing component, the first support includes a wider portion connected to the first pin and a narrower portion adjacent to the second pin.
[0015] As one embodiment of the atomizing component, in the unfolded state, the distance between the first support and the second pin is basically equal to the distance between the second support and the first pin.
[0016] As one embodiment of the atomizing component, the height of the liquid guiding element along the longitudinal direction of the tube is greater than the height of the heating element, and the liquid guiding element completely covers the heating element.
[0017] As one embodiment of the atomizing component, the support is connected to the middle of the heating element and its two ends extend toward the first pin and the second pin respectively.

[0020] As one embodiment of the atomizing component, several reinforcement holes are formed on the support portion.
[0021] As one embodiment of the atomizing component, the support portion has multiple first spikes distributed on both sides in the width direction.
[0022] As one embodiment of the atomizing component, the width of the first support portion or the second support portion is 0.2mm-6mm.
[0023] As one embodiment of the atomizing component, a second spike is provided at the free end of the support portion; and / or a second spike is provided on both sides opposite to the first pin and the second pin.

[0048] This application provides an aerosol atomizing device 100, as shown in FIG1. The aerosol generating device 100 can be used to atomize an aerosol generating matrix to generate aerosols. The aerosol atomizing device 100 includes an atomizing component 10 and a battery component 20. This application provides an embodiment of the atomizing component 10, as shown in FIG2 and FIG3. The atomizing component 10 includes a tube 1, a liquid guiding element 3 disposed in the tube 1, and a heating element 2 disposed in the liquid guiding element 3. A support portion 22 is provided on the heating element 2. The support portion 22 can provide support force to prevent the liquid guiding element 3 from deforming, so that the liquid guiding element 3 will not expand inward and compress the internal air passage space after absorbing the liquid matrix. At the same time, it can also reduce the pressure on the heating element 2 itself, ensuring the heating performance of the atomizing component 10.
[0049] Specifically, the heating element 2 includes a first pin 23, a second pin 24, and a heating portion 21 connected between the first pin 23 and the second pin 24. The heating element 2 also includes a support portion 22, which is spaced apart from the heating portion 21 along the longitudinal direction of the tube 1, and is located inside the liquid guiding element 3 to provide local radial support for the liquid guiding element 3. As an example, the heating portion 21 is made of metal sheets such as nickel, iron, stainless steel, iron-chromium-aluminum alloy, or nickel-iron alloy, etched into a structure such as a heating mesh or heating element, with a thickness of less than 0.06 mm.
[0050] The liquid guiding element 3 includes fibrous materials or microporous materials with capillary effect. For example, as an optional example, the heating element 2 is made of a heating mesh wound into a hollow cylinder, the interior of which forms part of the airflow channel 4 to allow air to pass through and carry aerosols. The liquid guiding element 3 is made of fiber cotton, which is wrapped around the periphery of the heating element 2 to provide a liquid matrix to the heating element 2 from all sides.
[0051] The atomizing assembly 10 provided in this embodiment has a heating element 2 with a proximal end 26 and a distal end 27. The support portion 22 includes a first support portion 221 spaced apart from the proximal end 26 along the longitudinal direction of the tube 1, and a second support portion 222 spaced apart from the distal end 27 along the longitudinal direction of the tube 1, which is used to radially support the liquid guiding element 3 on the upper and lower sides of the longitudinal direction of the heating element 2 to prevent it from expanding inward after absorbing the liquid matrix.
[0052] In one embodiment of this application, a circular oil guide hole 11 is provided on the side of the tube 1. The outer side of the liquid guiding element 3 is in close contact with the circular oil guide hole 11. E-liquid enters the liquid guiding element 3 along the circular oil guide hole 11 and is stored in the liquid guiding element 3. When the atomizing core is working, the heating element 2 heats and atomizes the e-liquid on the inner wall of the liquid guiding element 3 for the user to inhale.
[0053] In one embodiment of this application, the heating element 2 includes a laterally extending mesh heating section 21 connected to the first pin 23 and the second pin 24. The heating section 21 also includes a plurality of heat dissipation sections 25 connected to the main body of the heating section 21 and extending longitudinally to both ends of the main body of the heating section 21. After being powered on, the heat generated by the heating section 21 can be transferred to the heat dissipation sections 25, thereby increasing the heating area of the heating element 2 on the liquid guiding element 3. The heat dissipation sections 25 are also used to improve the support strength of the heating section 21, making the fit between the heating section 21 and the liquid guiding element 3 tighter and improving the stability of the heating element 2.
[0054] In one embodiment of this application, the tube 1 is made of metal to ensure the mechanical strength of the tube 1.
[0055] In one embodiment of this application, along the longitudinal direction of the tube 1, the height of the liquid guiding element 3 is greater than the height of the heating part 21, and the liquid guiding element 3 completely covers the heating part 21.
[0056] In one embodiment of this application, the edges of the first pin 23, the second pin 24 and the support portion 22 are all provided with a plurality of second spikes 28. The second spikes 28 have an auxiliary anchoring function. When the second spikes 28 contact the liquid guiding element 3, they can easily penetrate into the liquid guiding element 3 and play an anchoring role, effectively preventing the heating element 2 from shifting or loosening during use.
[0057] In a preferred embodiment of this application, referring to Figure 4, the support portion 22m is simultaneously provided with a reinforcing hole 223 and a first spike 224, which improves assembly flexibility while enhancing overall support. The state of the atomizing component 10 before and after absorbing the liquid matrix provided in this embodiment can be seen in Figures 18a and 18b. Figures 16a and 16b are before-and-after comparisons of the pore size of the liquid guiding element 3 of a conventional atomizing component after one day of liquid matrix absorption. Figures 18a and 18b are before-and-after comparisons of the pore size of the liquid guiding element 3 of the atomizing component 10 of this embodiment after one day of liquid matrix absorption. It can be seen that after one day of liquid matrix absorption, the liquid guiding element 3 of a conventional atomizing component expands significantly, causing the pore size to shrink. However, the pore size change of the liquid guiding element 3 of the atomizing component 10 of this embodiment after one day of liquid matrix absorption is relatively slight.
[0058] In one embodiment of this application, as shown in FIG4, the width d1 of the support portion 22 is 0.2mm-6mm, and the distance d2 between the first support portion 221 or the second support portion 222 and the first pin 34 or the second pin 24 is 0.2mm-3mm.
[0059] In one embodiment of this application, as shown in FIG5, the first support portion 221a is connected to the first pin 23a and extends toward the second pin 24a; the second support portion 222a is connected to the second pin 24a and extends toward the first pin 23a, or the second support portion 222a is connected to the first pin 23a and extends toward the second pin 24a. The first support portion 221a and the second support portion 222a together provide radial support for the liquid guiding element 3.
[0060] In one embodiment of this application, as shown in FIG6, the first support portion 221b extends in two directions from the first pin 23b, and the second support portion 222b extends in two directions from the second pin 24b, so as to enhance the stability of the overall structure of the heating element 2.
[0061] In one embodiment of this application, as shown in FIG7, the support portion 22c is connected to the middle of the heating portion 21c and its two ends extend toward the first pin 23c and the second pin 24c respectively, thereby improving the uniformity of the force on the heating element 3.
[0062] In one embodiment of this application, referring to FIG8, the extension length of the first support portion 221d is greater than the extension length of the second support portion 222d. Furthermore, the extension length of the first support portion 221d is substantially equal to the distance between the first pin 23d and the second pin 24d, allowing the first support portion 221d to form a closed-loop structure after bending, thus improving mechanical strength and stability. Additionally, the first support portion 221d and the second pin 24d have a longitudinal gap, preventing the first support portion 221d from contacting the second pin 24d and causing a short circuit after lateral bending. This embodiment provides a comparison of the atomizing component 10 before and after absorbing the liquid matrix, as shown in Figures 17a and 17b. Figures 16a and 16b show a comparison of the pore size of the liquid guiding element 3 of a conventional atomizing component after one day of absorbing the liquid matrix. Figures 17a and 17b show a comparison of the pore size of the liquid guiding element 3 of the atomizing component 10 of this embodiment after one day of absorbing the oil. It can be seen that after one day of absorbing the liquid matrix, the liquid guiding element 3 of a conventional atomizing component expands significantly, causing the pore size to shrink. However, the pore size change of the liquid guiding element 3 of the atomizing component of this embodiment after one day of absorbing the liquid matrix is relatively slight.
[0063] Furthermore, referring to FIG9, the first support portion 221e includes a wider portion 2211 connected to the first pin 23e and a narrower portion 2212 adjacent to the second pin 24e. Reducing the width of the portion of the first support portion 221e adjacent to the second pin 24e can further prevent the first support portion 221e from contacting the second pin 24e and causing a short circuit.
[0064] In one embodiment of this application, referring to FIG10, the first support member 221f is divided into a first part extending from the first pin 23f toward the second pin 24f and a second part extending from the second pin 24f toward the first pin 23f. Similarly, the second support member 222f is divided into a third part extending from the first pin 23f toward the second pin 24f and a fourth part extending from the second pin 24f toward the first pin 23f. This support structure extending from the four corners of the first pin 23f and the second pin 24f can increase the overall mechanical stability and force uniformity of the heating element 2 and improve the reliability of the contact between the heating element 2 and the liquid guiding element 3.
[0065] In some other embodiments, as shown in FIG11, the width of the first support portion 221g and / or the second support portion 222g gradually decreases along the extension direction. The diagonal structure can enhance the stability of the first support portion 221g and the second support portion 222g in supporting the liquid guiding element 3 through oblique support.
[0066] In some embodiments of this application, as shown in FIG12, a plurality of reinforcing holes 223 are formed on the support portion 22h, which can reduce the bending strength of the support portion 22h, making the support portion 22h easier to be rolled up and fit with the liquid guiding element 3, avoiding local warping, improving assembly flexibility, and reducing assembly difficulty.
[0067] In one embodiment of this application, as shown in FIG13, the support portion 22k has a plurality of first spikes 224 distributed on both sides in the width direction. When the support portion 22k is curled on the inner surface of the liquid guiding element 3, the first spikes 224 are used to anchor inside the liquid guiding element 3, so as to prevent misalignment between the support portion 22k and the liquid guiding element 3 when the liquid guiding element 3 expands, thereby enhancing the overall support force of the heating element 2 on the liquid guiding element 3.
[0068] In a preferred embodiment of this application, referring to FIG14, a first support portion 221p is connected to a first pin 23p and extends toward a second pin 24p, and a second support portion 222p is connected to a first pin 23p and extends toward a second pin 24p. This structure facilitates manufacturing and assembly. The extension length of the first support portion 221p is greater than the extension length of the second support portion 222p. Furthermore, the extension length of the first support portion 221p is approximately equal to the distance between the first pin 23p and the second pin 24p, allowing the first support portion 221p to form a closed-loop structure after bending, thus improving mechanical strength and stability. Furthermore, there is a longitudinal gap between the first support portion 221p and the second pin 24p, preventing the first support portion 221p from contacting the second pin 24p and causing a short circuit after lateral bending. The support portion 22p is simultaneously provided with a reinforcing hole 223 and a first spike 224, improving assembly flexibility while enhancing overall support strength.
[0069] In a preferred embodiment of this application, referring to FIG15, a first support portion 221q is connected to a first pin 23q and extends toward a second pin 24q, and a second support portion 222q is connected to a first pin 23q and extends toward a second pin 24q. This structure facilitates manufacturing and assembly. The first support portion 221q and the second support portion 222q together provide radial support for the liquid guiding element 3. A reinforcing hole 223 and a first spike 224 are simultaneously provided on the support portion 22q, improving assembly flexibility while enhancing overall support strength.
[0070] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
