Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic cigarettes, in particular to an atomization assembly, a manufacturing method of the atomization assembly, and an aerosol generating device. BACKGROUND

[0002] Cigarette smoke contains harmful substances such as tar, and long-term inhalation of these harmful substances can cause great harm to the human body. In order to overcome the harmful substances generated by cigarette combustion, low-hazard cigarette substitutes such as e-cigarette oil and heat-not-burn e-cigarettes have appeared. As the core component of an electronic cigarette, an atomization core plays a crucial role in the aerosol and other indicators formed by the electronic cigarette.

[0003] However, the atomization core used in traditional electronic cigarettes either has good rigidity but slightly poor aerosol taste, or has good aerosol taste but low rigidity, that is, traditional electronic cigarettes cannot simultaneously have good aerosol taste and high reliability. SUMMARY

[0004] Therefore, it is necessary to provide an atomization assembly, a manufacturing method of the atomization assembly, and an aerosol generating device to solve the above problems.

[0005] An atomization assembly comprises:

[0006] a base body, the base body being provided with a filling hole;

[0007] an atomization part, the atomization part being filled in the filling hole, the base body and the atomization part being made of porous materials, and the porosity of the base body being less than the porosity of the atomization part.

[0008] The traditional cotton atomization part is soft and easy to deform, which is not conducive to automatic assembly, and the cotton atomization part is also prone to oil leakage and other problems. The traditional ceramic atomization core has high strength but the aerosol produced by the traditional ceramic atomization core does not perform as well as the cotton atomization part. The atomization assembly of the present application is provided with a filling hole on the base body, and the atomization part is arranged in the filling hole. The atomization part has high porosity, which can improve the oil guiding efficiency of the atomization medium such as e-liquid, so that the generated aerosol has good taste. The base body has low porosity, which can reduce the risk of oil leakage. In addition, the base body with low porosity has better structural strength, which can better support the structure of the whole atomization assembly and facilitate the automatic assembly of the atomization assembly with other components. In other words, the atomization assembly of the present application can ensure the taste of the aerosol while considering the overall structural strength.

[0009] In one of the embodiments, the filling hole is used for filling the atomization slurry to be solidified to form the atomization part.

[0010] In one of the embodiments, the base body is provided with an atomization cavity penetrating through in the first direction, and the filling holes are arranged on the side circumferential surface of the base body. The atomization medium can be conducted to the atomization cavity through the base body and the atomization part, and is atomized in the atomization cavity to form the aerosol for being puffed.

[0011] In one of the embodiments, the base body is a honeycomb ceramic base body. The honeycomb ceramic is a new type of ceramic with a structure similar to a honeycomb shape and a plurality of holes. The plurality of holes can be considered as the filling holes for filling the atomization slurry, that is, the honeycomb ceramic base body can be used as a filling carrier of the atomization slurry. The shape of the honeycomb ceramic base body can be a regular shape such as a columnar shape, or can be an irregular shape. In other words, as long as the honeycomb ceramic base body can be used as a filling carrier of the atomization slurry, the specific state of the base body is not limited. Taking the atomization slurry as cotton slurry as an example, the atomization slurry in the filling holes of the honeycomb ceramic base body can be solidified to form a cotton atomization part. The honeycomb ceramic base body has higher strength, the cotton atomization part has soft texture and good oil guiding effect, and the conducting effect of the atomization medium and the taste of the aerosol can be ensured.

[0012] In one of the embodiments, the number of the filling holes is set to be multiple, and the multiple filling holes are uniformly distributed on the side circumferential surface of the base body. The increase of the number of the filling holes is equivalent to the increase of the structure ratio of the atomization part, and the uniform distribution of the filling holes means the uniform distribution of the atomization part, which is beneficial to the timely conduction and atomization of the atomization medium.

[0013] In one of the embodiments, the filling hole includes a first blind hole and a second blind hole, the first blind hole is exposed to the outer side circumferential surface of the base body, and the second blind hole is exposed to the inner side circumferential surface of the base body. In this embodiment, the atomization part of the first blind hole can conduct the atomization medium to the inside of the base body, and the atomization medium is conducted to the atomization part of the second blind hole from the inside of the base body. Since there is still a certain base body structure between the first blind hole and the second blind hole, the overall structural strength can be improved.

[0014] In one of the embodiments, the filling hole penetrates through the base body in a direction perpendicular to the first direction. The atomization part in the filling hole can conduct the atomization medium from the outer side circumferential surface of the base body to the inner side circumferential surface, that is, directly to the atomization cavity, and the conduction effect of the atomization medium is better, which can ensure the conduction effect of the atomization medium and the taste of the aerosol.

[0015] In one of the embodiments, the base body is a ceramic base body, and the atomization part is a cotton atomization part.

[0016] In one of the embodiments, the atomization assembly further includes a heating element, and the heating element is at least partially located in the atomization cavity. The heating element can generate heat to improve the atomization speed of the atomization medium, so as to generate the aerosol as soon as possible.

[0017] In one of the embodiments, the heating element comprises an electrically conductive part and a heating part connected with the electrically conductive part, the heating part is at least partially arranged in the atomization cavity, and the heating part can comprise at least one of a heating sheet, a heating net, a heating wire, and a resistance paste film. The electrically conductive part can be connected with a power supply to heat the heating part to heat the atomization medium.

[0018] The present application also relates to an aerosol generating device comprising a main body and the atomization assembly according to any one of the above embodiments, the atomization assembly is arranged in the main body, and the main body is provided with a storage cavity for storing the atomization medium, and the storage cavity is used to deliver the atomization medium to the atomization assembly.

[0019] The aerosol generating device can be provided with the atomization assembly according to any one of the above embodiments, and therefore, the aerosol generating device also has at least the following beneficial effects: the base body of the atomization assembly is provided with a filling hole, the filling hole is provided with an atomization part, the atomization part has a high porosity, the oil guiding efficiency of the atomization medium such as tobacco tar can be improved, and the generated aerosol has a good taste. The base body has a low porosity, which can reduce the risk of oil leakage, and the base body with a low porosity has a better structural strength, which can better support the structure of the whole atomization assembly and facilitate the subsequent automatic assembly of the atomization assembly with other components. In other words, the atomization assembly of the present application can ensure the taste of the aerosol while considering the overall structural strength.

[0020] The present application also relates to a manufacturing method of an atomization assembly, which is used to manufacture the atomization assembly according to any one of the above embodiments, and the manufacturing method of the atomization assembly comprises the following steps:

[0021] obtaining a base body provided with a filling hole;

[0022] obtaining a mixed and uniform atomization paste;

[0023] filling the atomization paste into the filling hole;

[0024] curing the atomization paste filled into the filling hole to obtain the atomization assembly.

[0025] The manufacturing method of the atomization assembly provides a space for filling the atomization slurry in the filling hole. After the atomization slurry is injected into the filling hole, the atomization slurry is solidified to be fixedly connected with the base body, that is, the atomization part after the atomization slurry is solidified is fixedly connected with the base body. The atomization part of the atomization assembly formed by the manufacturing method has high porosity, which can improve the oil guiding efficiency of the atomization medium such as tobacco tar, so that the aerosol generated has good taste. The base body has low porosity, which can reduce the risk of oil leakage. In addition, the base body with low porosity has better structural strength, which can better support the structure of the whole atomization assembly, and is conducive to the subsequent automatic assembly of the atomization assembly and other components.

[0026] In one of the embodiments, the step of filling the atomization slurry into the filling hole includes filling the atomization slurry into the filling hole in a vacuum environment. For example, when the atomization slurry is cotton slurry, the cotton slurry can flow into the filling hole of the base body when the base body is immersed in the cotton slurry. However, some gas may still remain in the filling hole when the cotton slurry instantaneously flows into the filling hole. Therefore, the vacuum device is used to perform vacuum treatment on the cotton slurry and the base body in the cotton slurry, so that the gas in the filling hole is discharged, the cotton slurry fills the filling hole, the remaining gas in the filling hole is eliminated, and the atomization part after the cotton slurry is solidified is free of defects such as bubbles.

[0027] In one of the embodiments, the atomization assembly further includes a heating element, and the heating element is a heating sheet or a heating net. The step of obtaining the base body with the filling hole further includes obtaining the base body with the heating element embedded by inlay molding and with the filling hole. For example, when the atomization slurry is cotton slurry, the heating element is fixed on the base body before the atomization part. When the base body is covered by the cotton slurry and the cotton slurry is solidified, part of the cotton slurry may cover the heating element. At this time, the solidified cotton slurry on the heating element can be cleaned, so that the heating part and the conductive part for conducting electricity of the heating element are exposed, and the heating element can work normally.

[0028] In one of the embodiments, the atomization assembly further includes a heating element, and the heating element is a thick-film printed resistance film. After the step of solidifying the atomization slurry filled into the filling hole to obtain the atomization assembly, the step further includes printing resistance slurry on the atomization assembly and solidifying the resistance slurry to form the resistance film. After the base body and the atomization part are manufactured, the resistance heating area formed by printing the resistance slurry is not covered by the atomization slurry.

[0029] In one of the embodiments, the step of solidifying the atomization slurry to form the atomization part includes baking the base body and the atomization slurry filled in the filling hole to solidify the atomization slurry. For example, when the atomization slurry is cotton slurry, baking can accelerate the loss of water in the cotton slurry to solidify. BRIEF DESCRIPTION OF DRAWINGS

[0040] In order to make the above objectives, features and advantages of the present application more apparent, the specific embodiments of the present application will be described in detail below with the accompanying drawings. In the following description, a lot of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0041] Please refer to Figure 1 , Figure 2 ,Figure 3 and Figure 4 In some embodiments, the present application provides an atomization assembly 10, which comprises a base body 100 and an atomization part 200. The base body 100 is provided with a filling hole 110, and the atomization part 200 is filled in the filling hole 110, and the filling hole 110 is used for filling the atomization slurry to solidify the atomization part 200. The base body 100 and the atomization part 200 are both made of porous materials, and the porosity of the base body 100 is less than that of the atomization part 200. Wherein, the base body 100 and the atomization part 200 made of porous materials exhibit a "porous" morphology at the micro level, and the atomization medium such as tobacco tar can be transmitted inside by capillary action.

[0042] The base body 100 can be made of ceramic or glass, and more specifically, the material of the porous ceramic base body 100 can be selected from zirconium oxide, silicon oxide, aluminum oxide, etc. The atomization part 200 can be made of cotton, and the atomization part 200 can be formed by drying and solidifying the cotton slurry in the filling hole 110 of the base body 100. For example, the base body 100 can be a honeycomb ceramic base body, and the atomization part 200 can be a cotton atomization part. The honeycomb ceramic base body 100 has higher strength, and the cotton atomization part has soft texture and good oil guiding effect, which can ensure the conduction effect of the atomization medium and the taste of the aerosol. Honeycomb ceramic is a new type of ceramic with many pores in a honeycomb-like structure. The many pores on the honeycomb ceramic can be considered as filling holes for filling the atomization slurry, that is, the honeycomb ceramic base body can be used as a filling carrier for the atomization slurry. Wherein, the shape of the honeycomb ceramic base body can be a relatively regular shape such as a column, or can be an irregular shape. In other words, as long as the honeycomb ceramic base body can be used as a filling carrier for the atomization slurry, the specific state of the base body is not limited here. Figure 2 In the embodiment shown in FIG. 1A, the filling hole 110 of the base body 100 has not yet been provided with the atomization part 200; in the embodiment shown in FIG. 1B, the filling hole 110 of the base body 100 has already been provided with the atomization part 200; in the embodiment shown in FIG. 1C, the structure of the base body 100 is hidden, and the general shape of the atomization part 200 in the filling hole 110 of the base body 100 is shown, and the purpose of the figure is only to facilitate understanding, and does not constitute a specific limitation on the present application. Figure 3 Figure 4 It should be noted that the traditional cotton atomization part has soft texture and is easy to deform, which is not conducive to automatic assembly, and the cotton atomization part is also prone to oil leakage and other problems. The traditional ceramic atomization core has high strength, but the taste of the aerosol produced by the ceramic atomization core is not as good as that of the cotton atomization part.

[0043] It should be noted that the traditional cotton atomization part has soft texture and is easy to deform, which is not conducive to automatic assembly, and the cotton atomization part is also prone to oil leakage and other problems. The traditional ceramic atomization core has high strength, but the taste of the aerosol produced by the ceramic atomization core is not as good as that of the cotton atomization part.

[0044] ​The filling hole 110 is arranged on the base body 100, and the atomization part 200 is arranged in the filling hole 110. The atomization part 200 has a high porosity, which can improve the oil guiding efficiency of the atomization medium such as tobacco tar, so that the generated aerosol has a good taste. The base body 100 has a low porosity, which can reduce the risk of oil leakage. In addition, the base body 100 with a low porosity has a better structural strength, which can better support the structure of the atomization assembly 10 and facilitate the subsequent automatic assembly of the atomization assembly 10 with other components. In other words, the atomization assembly 10 can ensure the taste of the aerosol while considering the overall structural strength.

[0045] Please refer to Figure 1 In some embodiments, the base body is provided with an atomization cavity penetrating in the first direction. Specifically, the base body 100 can be in a columnar shape, the first direction can be the axial direction of the base body 100, the atomization cavity 120 is arranged in the axial direction of the base body 100, and the filling hole 110 is arranged on the side surface of the base body 100. The atomization medium can be conducted to the atomization cavity 120 through the base body 100 and the atomization part 200, and atomized in the atomization cavity 120 to form an aerosol for smoking.

[0046] Specifically, as shown in Figure 1 and Figure 2 In some embodiments, the number of filling holes 110 is multiple, and the multiple filling holes 110 are uniformly distributed on the side surface of the base body 100. Increasing the number of filling holes 110 is equivalent to increasing the structure ratio of the atomization part 200, and the uniform distribution of the filling holes 110 means the uniform distribution of the atomization part 200, which is beneficial to the timely conduction and atomization of the atomization medium.

[0047] More specifically, as shown in Figure 2 In some embodiments, the filling hole 110 includes a first blind hole 111 and a second blind hole 112. The first blind hole 111 is exposed to the outer side surface of the base body 100, and the second blind hole 112 is exposed to the inner side surface of the base body 100. In this embodiment, the atomization part 200 of the first blind hole 111 can conduct the atomization medium to the inside of the base body 100, and the atomization medium is conducted to the atomization part 200 of the second blind hole 112 from the inside of the base body 100. Since there is still a certain structure of the base body 100 between the first blind hole 111 and the second blind hole 112, the overall structural strength can be improved.

[0048] In other embodiments, the filling hole 110 can penetrate the substrate 100 in a direction perpendicular to the first direction of the substrate 100, i.e., the filling hole 110 can penetrate the substrate 100 in a radial direction of the substrate 100, when the substrate 100 is substantially cylindrical. The atomization portion 200 in the filling hole 110 can conduct the atomization medium from the outer circumferential surface of the substrate 100 to the inner circumferential surface, i.e., directly into the atomization cavity 120, and the atomization medium can be better conducted, which can ensure the conduction effect of the atomization medium and the taste of the aerosol.

[0049] Please refer to Figure 5 and Figure 6 In some embodiments, the atomization assembly 10 further comprises a heating element, which is at least partially located in the atomization cavity 120. The heating element can generate heat to increase the atomization speed of the atomization medium, so as to generate the aerosol as soon as possible.

[0050] Specifically, as shown in Figure 5 and Figure 6 In some embodiments, the heating element comprises a conductive portion 320 and a heating portion 310 connected to the conductive portion 320, and the heating portion 310 is at least partially located in the atomization cavity 120. For example, the heating portion can comprise at least one of a heating sheet, a heating net, a heating wire, and a resistance paste film. The conductive portion 320 can be connected to a power supply to heat the heating portion 310 to heat the atomization medium.

[0051] In addition, the present application also relates to an aerosol generating device, which comprises a main body (not shown) and the atomization assembly 10 according to any one of the above embodiments, and the atomization assembly 10 is arranged in the main body. The main body is provided with a storage cavity for storing the atomization medium, and the storage cavity is used to deliver the atomization medium to the atomization assembly 10. The aerosol generating device can further comprise a power supply device for supplying power to the heating element 300.

[0052] The aerosol generating device described above can be provided with the atomization assembly 10 described in the above embodiments, and therefore, the aerosol generating device also has at least the following beneficial effects: the substrate 100 of the atomization assembly 10 is provided with the filling hole 110, and the atomization portion 200 is arranged in the filling hole 110. The atomization portion 200 has a high porosity, which can improve the oil conduction efficiency of the atomization medium such as tobacco tar, and the generated aerosol has a good taste. In addition, the substrate 100 has a low porosity, which can reduce the risk of oil leakage. Furthermore, the substrate 100 with a low porosity has a better structural strength, which can better support the structure of the atomization assembly 10, and facilitate the subsequent automatic assembly of the atomization assembly 10 with other components. In other words, the atomization assembly 10 of the present application can ensure the taste of the aerosol while considering the overall structural strength.

[0053] Further, as Figure 7 The present application also relates to a manufacturing method of the atomization assembly 10, for manufacturing the atomization assembly 10 of any of the above embodiments, the manufacturing method of the atomization assembly 10 comprising the following steps:

[0054] S100, obtaining a base body with filling holes;

[0055] S200, obtaining a mixed uniform atomization slurry;

[0056] S300, filling the atomization slurry into the filling holes;

[0057] S400, solidifying the atomization slurry filled into the filling holes to obtain the atomization assembly.

[0058] The manufacturing method of the atomization assembly 10, as Figure 1 and Figure 2 The filling holes 110 on the base body 100 provide space for the filling of the atomization slurry. As Figure 3 indicated, after the atomization slurry is injected into the filling holes 110, the solidification of the atomization slurry can make it fixedly connected with the base body 100, that is, the atomization part 200 after the solidification of the atomization slurry is fixedly connected with the base body 100. The atomization part 200 of the atomization assembly 10 formed by this manufacturing method has a higher porosity, which can improve the oil guiding efficiency of the atomization medium such as tobacco tar, and the aerosol generated has a better taste. The base body 100 has a lower porosity, which can reduce the risk of oil leakage, and the base body 100 with a lower porosity has a better structural strength, which can better support the structure of the whole atomization assembly 10, and is beneficial to the subsequent automatic assembly of the atomization assembly 10 with other components.

[0059] Specifically, in some embodiments, the S300 step of filling the atomization slurry into the filling holes comprises filling the atomization slurry into the filling holes in a vacuum environment, which is further explained as follows:

[0060] S310, providing a container containing the atomization slurry;

[0061] S320, placing the base body 100 into the container containing the atomization slurry so that the atomization slurry enters the filling holes 110. Taking the atomization slurry as cotton slurry for example, the container contains cotton slurry, and the base body 100 is immersed in the cotton slurry, so that the cotton slurry can flow into the filling holes 110, and then the solidification of the cotton slurry can form the atomization part 200.

[0062] S330, placing the container containing the base body 100 and the atomization slurry into a vacuum device;

[0063] S340, a vacuum process is performed using the vacuum device to expel the gas from the filling hole 110, allowing the atomized slurry to enter the filling hole 110. The vacuum device can be a vacuum pump. Taking cotton pulp as an example, when the substrate 100 is immersed in the cotton pulp, the pulp can flow into the filling hole 110 of the substrate 100. However, the filling hole 110 originally contains gas, and some gas may remain in the filling hole 110 after the cotton pulp rushes in. Therefore, the vacuum device is used to perform a vacuum process on the cotton pulp and the entire substrate 100 within it, expelling the gas from the filling hole 110 and eliminating any residual gas, thus preventing defects such as air bubbles in the atomized section 200 after the cotton pulp has solidified. When the gas in the filling hole 110 is expelled, the additional space in the filling hole 110 can draw in the cotton pulp; that is, the hydraulic pressure of the cotton pulp itself will further press the cotton pulp into the filling hole 110, thereby filling the filling hole 110 completely.

[0064] Specifically, in some embodiments, step S400 of curing the atomizing slurry within the filling holes to obtain the atomizing assembly includes: baking the substrate 100 and the atomizing slurry filling the filling holes 110 to cure the atomizing slurry and form the atomizing portion 200. Taking cotton pulp as an example, baking can accelerate the curing process by reducing moisture loss from the cotton pulp.

[0065] In some embodiments, the atomizing assembly further includes a heating element, which is a thick-film printed resistive film. After the step of curing the atomizing paste within the filling holes to obtain the atomizing assembly, the assembly further includes: printing resistive paste onto the atomizing assembly and curing the resistive paste to form the resistive film. The formed resistive film ensures that the resistive heating area is not covered by the atomizing paste.

[0066] In some embodiments, the heating element is directly assembled with the cured atomizing assembly, such that the heating part of the heating element is at least partially located within the atomizing cavity of the atomizing assembly, which will not be described in detail here.

[0067] In some embodiments, step S100 of obtaining a substrate with filled holes further includes obtaining a substrate with filled holes in which the heating element is embedded by an insert molding process, as explained below:

[0068] S101, such as Figure 5 to Figure 6 As shown, a heating element 300 is provided on the substrate 100, and the heating element is embedded in the substrate.

[0069] S102, cleaning the solidified atomized slurry on the heating element 300. Taking the example that the atomized slurry is cotton slurry, since the heating element 300 is fixed on the base body 100 before the atomizing part 200, when the base body 100 is covered by the cotton slurry and the cotton slurry solidifies, part of the cotton slurry may cover the heating element 300. At this time, the solidified cotton slurry on the heating element 300 needs to be cleaned, so that the heating part 310 and the conductive part 320 for conducting electricity of the heating element 300 are exposed, and the heating element 300 can work normally.

Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other orders. Moreover, Figure 5 At least part of the steps in the flowcharts can include multiple steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least part of other steps or steps or stages in other steps.
