Description

Technical Field

[0001] This application relates to the field of electronic atomization device technology, specifically to a design method for an atomizing crucible and an aerosol generation device. Background Technology

[0002] An electronic atomizing device is an electronic device that atomizes a substance into an inhalable aerosol. The atomized substance can be wholly or partially atomized into an inhalable aerosol by the electronic device. Atomized substances mainly include liquid tobacco, tobacco leaves, and paste-like atomized substances.

[0003] Currently, there are relatively few types of vaping devices that use paste as the atomizing agent. Most of them borrow from electronic cigarettes and heated tobacco products (HNB) in their heating and atomization structure design. However, due to the different heating targets, these devices are not entirely suitable for paste-shaped atomizers. Because the physicochemical properties of paste-shaped atomizers differ from those of tobacco and e-liquid, existing vaping devices often cannot effectively adapt to the characteristics of paste-shaped atomizers, leading to a series of usage problems. For example, the vapor production rate is usually slow, which affects the user experience; the heating consistency is poor, which may result in inconsistent taste and intensity with each puff; in addition, there are more residues during the heating process, which not only affects the cleaning and maintenance of the device but may also change the original flavor of the paste-shaped atomizer; localized dry burning also frequently occurs, easily producing unwanted burnt flavors and affecting the overall smoking experience. Summary of the Invention

[0022] Using the first bottom dimension of the crucible as the decision variable, and aiming to maximize the value of the objective function, the objective function is solved to obtain the value of the first bottom dimension.

[0023] Optionally, the entire crucible body is generally a thin-walled frustum or a thin-walled prism with the opening facing upwards.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Application Overview

[0044] In related technologies, the crucible in electronic atomizing devices is generally a thin-shell cylindrical structure with a single-sided opening. Because the cylindrical crucible has uniform dimensions from top to bottom, the paste-like atomized material may not be able to quickly form a high-temperature zone during the initial heating phase, thus affecting the smoke generation efficiency. Furthermore, during subsequent heating, the upper part may evaporate too quickly while the lower part is underheated. This uneven heating results in low overall heating efficiency and a large amount of residual paste-like atomized material after use.

[0045] To address the aforementioned issues, this embodiment of the application sets the lower part of the crucible body as a thin-walled platform structure (e.g., a frustum of a cylinder or a truncated pyramid) with an upward-opening shape and a "large opening and small base." However, the shape of the thin-walled platform directly impacts the overall performance of the electronic atomizing device and the user's vaping experience. Specifically, the shape of the paste-like atomized material within the crucible body is determined by the shape of the lower part of the thin-walled platform; and the shape of the atomized material directly affects its temperature distribution throughout the heating process. This temperature distribution simultaneously influences both the initial smoke generation time and the amount of smoke generated during subsequent heating. These two parameters have a significant impact on the user experience of the electronic atomizing device, but they are a set of parameters that are difficult to balance simultaneously.

[0046] This application provides a design method for a crucible containing atomized material in an electronic atomizing device. An objective function is constructed based on a weighted sum of a first parameter positively correlated with the initial smoke generation time of the atomized material and a second parameter positively correlated with the smoke generation amount. This determines the contour data of the crucible so that the top of the paste-like atomized material can quickly form a high-temperature zone in the initial heating stage for rapid smoke generation; and maintain a large smoke generation amount during subsequent heating processes, thereby improving the overall performance of the device and enhancing the user's vaping experience.

[0047] After introducing the basic principles of this application, various non-limiting embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0051] Exemplary methods

[0052] Figure 5 This is a flowchart illustrating the design method of an atomizing crucible provided in one embodiment of this application. Figure 5 The method described is performed by a computing device (e.g., a server), but this application embodiment is not limited thereto.

[0053] In this embodiment, the lower part of the crucible is a thin-walled platform with an upward opening, used to contain a paste-like atomized material; the top dimension of the thin-walled platform is larger than the bottom dimension of the thin-walled platform; the atomized material is used to generate an aerosol after absorbing the heat generated by the heating component fitted on the lower part of the crucible.

[0054] like Figure 5 As shown, the method includes the following:

[0055] Step S510: Construct an objective function based on the weighted sum of the first and second parameters of the crucible body; the first parameter is positively correlated with the initial smoke generation rate of the atomized material; the second parameter is positively correlated with the smoke generation amount of the atomized material.

[0056] In this embodiment of the application, the lower part of the crucible is used to hold the paste-like atomized material. Before use, the atomized material generally needs to be added to the lower part of the crucible and compacted.

[0057] In this embodiment, the lower part of the crucible is approximately a thin-walled platform with an open top surface; the thin-walled platform can be considered as the middle part of a three-dimensional shape cut by two parallel planes. The top dimension of the thin-walled platform is larger than the bottom dimension, meaning that the radius, diameter, side length, perimeter, area, etc., of the top of the thin-walled platform are larger than the corresponding dimensions of the bottom. Simply put, the thin-walled platform has an overall structure of "large opening and small bottom".

[0058] In the embodiments of this application, the thin-walled frustum may include a frustum of a cylinder, a frustum of a prism, an elliptical frustum, etc., that is, the bottom surface (also known as the lower bottom surface) and the top surface (also known as the upper bottom surface) of the thin-walled frustum may be circular, polygonal, elliptical, etc.; of course, the bottom surface (or top surface) of the thin-walled frustum may also be other shapes.

[0059] In this embodiment, the top dimension of the thin-walled platform is greater than the bottom dimension, which can mean that the radius, diameter, side length, perimeter, area, and other dimensions of the top of the thin-walled platform are greater than the corresponding dimensions of the bottom. Simply put, the thin-walled platform has an overall structure that is "large at the top and small at the bottom".

[0060] It should be noted that the bottom surface of the thin-walled platform can generally be set as a plane; in some cases, the bottom surface of the thin-walled platform can also be set as a curved surface, such as a sphere. The edges of the thin-walled platform (e.g., bottom edge, top edge, side edge) can be provided with chamfers or rounded corners.

[0061] In this embodiment, the upper part of the crucible is generally configured as a cavity, which serves as a space for the smoke generated by the atomized material to mix with the incoming air. The upper part of the crucible can be flexibly configured according to actual conditions. For example, the entire crucible can be configured as a platform, and the upper part of the crucible can be configured as a hollow cylindrical shape, etc.; as long as the upper part of the crucible has a cavity, it is acceptable.

[0062] In this embodiment, the first parameter is used to characterize the initial smoke generation rate of the atomized material. The larger the first parameter, the faster the initial smoke generation rate of the atomized material and the shorter the initial smoke generation time, meaning that the atomized material is locally heated to the smoke generation temperature more quickly.

[0063] The inventors discovered through experiments that the edge of the atomized material heats up faster during the initial heating stage. This is because the edge of the atomized material, due to its larger radial dimension, has a greater thermal resistance. Simultaneously, this area can receive a more sufficient heat source from the unused heating element above it. Therefore, the atomized material is consumed and aerosol is generated first at the edge of the atomized material's top. Specifically, the first parameter can be used to represent the radial thermal resistance of the atomized material's top.

[0064] In this embodiment, the second parameter is used to represent the amount of smoke produced by the atomized material. In practical applications, the amount of smoke produced by the atomized material is greatly affected by the contact area between the atomized material and the crucible body; specifically, the second parameter can be used to represent the contact area between a predetermined amount of atomized material and the crucible body after it has been filled and flattened.

[0065] In this embodiment, the objective function is constructed based on the weighted sum of the first and second parameters of the crucible. Furthermore, the value of the objective function is numerically equal to the weighted sum of the first and second parameters of the crucible.

[0066] In this embodiment, the weight values ​​of the first parameter and the second parameter can be determined according to the application requirements of the electronic atomizing device. If the electronic atomizing device tends to pursue a faster initial vapor production rate, the weight value corresponding to the first parameter needs to be increased; if the electronic atomizing device tends to pursue a consistently rich flavor, the weight value corresponding to the second parameter needs to be increased.

[0067] Step S520: With the goal of maximizing the value of the objective function, solve the objective function to obtain the contour data of the crucible body.

[0068] In this embodiment of the application, solving the objective function may refer to using the contour data of the crucible as a decision variable, constructing a model based on the decision variable and the objective function, optimizing the model with the goal of maximizing the value of the objective function, and obtaining the contour data of the crucible based on the optimal solution of the model.

[0069] In this embodiment of the application, the contour data that maximizes the objective function is the optimal solution of the objective function; at this time, both the first parameter and the second parameter can obtain large values, and the crucible body manufactured accordingly can take into account both the initial smoke generation rate and the amount of smoke generated by the atomized material.

[0070] In this embodiment, the contour data of the crucible body can be the dimensions of the crucible body. In some cases, some dimensions of the crucible body can be predetermined based on the external dimensions of the electronic atomizing device, and then the objective function can be solved to obtain the remaining dimensions of the crucible body.

[0071] In this embodiment, an objective function is constructed based on the weighted sum of a first parameter positively correlated with the initial smoke generation time of the atomized material and a second parameter positively correlated with the smoke generation amount. The contour data of the crucible body is then determined based on the optimal solution of the objective function so that the top of the paste-like atomized material can quickly form a high-temperature zone in the initial heating stage to generate smoke quickly; and maintain a large smoke generation amount in the subsequent heating process, thereby improving the overall performance of the smoking device and enhancing the user's smoking experience.

[0072] based on Figure 5 In addition to the method described in the embodiments of this specification, some specific implementation schemes of the method are also provided, which will be described below.

[0073] Optionally, the heating element is a uniform heating element disposed in close contact with the outer surface of the crucible body;

[0074] The first parameter is the first top dimension of the atomized material after a predetermined amount of atomized material has been filled and flattened in the crucible;

[0075] The second parameter is the contact area between the atomized material and the outer side of the crucible after the predetermined amount of atomized material is filled and flattened inside the crucible.

[0076] In this embodiment, the heating element can be used to uniformly heat the lower part of the crucible body, so that the surface of the paste-like atomized material is heated. The heating element can be a uniformly arranged mesh of resistance wires.

[0077] In this embodiment, the first top dimension can refer to the size of the top of the atomized material after a predetermined amount of atomized material has been filled and flattened in the crucible. Specifically, the first bottom dimension is the radius, diameter, or circumference of the bottom surface of the atomized material after it has been filled and flattened in the crucible. As the first bottom dimension increases, the top surface of the atomized material will have a greater thermal resistance in the radial direction, which increases the heat absorption power of the area near the inner wall of the crucible on the top surface of the atomized material, and the time it takes for the top edge of the atomized material to reach the smoke temperature is also shorter, that is, the initial smoke generation rate is faster.

[0078] In this embodiment, the outer contact area is the contact area between the atomized material and the side of the crucible after a predetermined amount of atomized material has been packed and flattened inside the crucible. The inventors' experiments have shown that increasing the outer contact area is beneficial for enhancing heat exchange and achieving a sustained increase in overall temperature. Therefore, the second parameter is set as the outer contact area.

[0079] Please see Figure 4 When the lower part of the crucible is a thin-walled frustum, the objective function can be Q = w1·r2 + w2·S, where r2 is the first top dimension, that is, the radius of the top surface of the atomized material after it is filled and flattened in the crucible; S is the outer contact area, and w1 and w2 are the weight values ​​corresponding to the first top dimension r2 and the outer contact area S, respectively, which can be determined according to the application requirements of the electronic atomization device.

[0080] After the atomized material is filled and flattened in the crucible, it has a similar relationship with the crucible; after determining the shape of the crucible, some of the constraint conditions of the crucible can be determined according to the shape of the crucible.

[0081] For example, when the lower part of the crucible is a thin-walled frustum, the following relationships exist between the atomized material and the various dimensions of the crucible:

[0082]

[0083] In the formula, h is the filling height of the predetermined amount of atomized material in the crucible; H is the inner depth of the crucible; r1 is the radius of the bottom of the atomized material after it has been filled and flattened in the crucible; r2 is the first top dimension, that is, the radius of the top surface of the atomized material after it has been filled and flattened in the crucible; S is the outer contact area; and V is the volume of the predetermined amount of atomized material.

[0084] In this embodiment, if the electronic atomizing device needs a faster initial vapor production rate, a larger first top dimension r2 is required as the primary objective, resulting in a larger w1 and a smaller w2. This gives the top surface of the atomized material a greater thermal resistance in the radial direction and a sufficient distance from the top of the heating element, allowing the area near the inner wall of the crucible to have a large heat absorption capacity. This enables the local maximum temperature to be formed and the vapor production temperature to be reached in a short time, thus achieving a shorter initial vapor production time. If the electronic atomizing device needs to maintain a strong flavor throughout the inhalation process, a larger outer contact area S is required as the primary objective, resulting in a smaller w1 and a larger w2. This gives the atomized material a larger overall heat absorption area and a larger filling height, meaning a smaller overall radial dimension and correspondingly lower thermal resistance. This increases the heat transfer flow rate of the atomized material, resulting in a sustained high temperature rise rate and a large vapor production during heating.

[0085] Figure 6a The diagram shown is a schematic representation of the temperature distribution of the paste-like atomized material provided in the embodiments of this application during the initial heating stage; as shown... Figure 6a As shown, during the initial heating phase, the top of the paste-like atomized material has a larger radial dimension and therefore a greater thermal resistance. Simultaneously, this area can receive more heat from the unused heating elements above, resulting in the formation of the highest temperature region I at the edge of the atomized material's top. Below the top of the atomized material, the area close to the side of the crucible is also heated first, forming a higher temperature region II. The larger the size of the paste's top, the smaller the highest temperature region I becomes, but the greater the temperature difference between the highest temperature region I and the higher temperature region II.

[0086] Figure 6b The diagram shown is a schematic representation of the temperature distribution of the paste-like atomized material provided in the embodiment of this application during the intermediate heating stage; as shown... Figure 6b As shown, during the intermediate heating stage, the edge of the atomized material's top has already been consumed. At this point, through further heat conduction and diffusion, the higher-temperature region b of the atomized material becomes the bottom, while the highest-temperature region I extends to the top and sides. The central region of the paste remains a lower-temperature region. Because the bottom has a smaller radial dimension and lower thermal resistance, it is easier to form a more uniform temperature distribution without creating localized high-temperature zones. The larger the size of the first top of the atomized material, the smaller the highest-temperature region I becomes, and the closer it is to the top of the paste. Similarly, the higher-temperature region II also becomes smaller and moves closer to the bottom. Furthermore, the greater the temperature difference between the highest-temperature region I and the higher-temperature region II, the larger the corresponding unlabeled lower-temperature region in the center becomes.

[0087] Figure 6c The diagram shown is a schematic representation of the temperature distribution of the paste-like atomized material provided in the embodiment of this application during the post-heating stage; as shown... Figure 6cAs shown, in the post-heating stage, the highest temperature region I of the atomized material will be concentrated at the bottom. Meanwhile, the higher temperature region II is distributed throughout the atomized material except for the highest temperature region I. At this point, the atomized material as a whole has been sufficiently heated, with the bottom of the atomized material receiving more heat due to its lower thermal resistance, resulting in a greater temperature rise rate and thus becoming the highest temperature region I in the post-heating stage. The larger the size of the top of the paste, the smaller the highest temperature region I becomes, and the closer it is to the bottom of the atomized material, with a lower temperature. When the size of the first top of the atomized material reaches a certain size, the temperature of the highest temperature region I approaches that of the higher temperature region II, meaning the entire surface of the atomized material achieves a relatively uniform temperature distribution. When the size of the top of the paste continues to increase to a certain size, the higher temperature region II becomes the highest temperature region, at which point the temperature rise rate is smaller in the later stages of heating.

[0088] Of course, the objective function can be transformed into Q = w3·r2 + S or Q = r2 + w4·S, where w3 and w4 are weight values, which can be determined based on the ratio of w1 and w2.

[0089] In this embodiment, an objective function is constructed based on the weighted sum of the first top dimension and the outer contact area of ​​the atomized material; the contour data of the crucible body is obtained based on the optimal solution of the objective function. This balances the mutually exclusive effects of initial smoke generation time and smoke generation amount, helping to improve the overall user experience of the electronic atomization device.

[0090] Optionally, the method further includes:

[0091] Obtain the constraint conditions for the crucible body; the constraint conditions include at least: the ratio of the first top dimension to the first bottom dimension is not greater than a preset ratio, and the first bottom dimension is the bottom dimension inside the thin-walled platform; or, the taper of the atomized material is not greater than a preset taper.

[0092] The step of solving the objective function with the goal of maximizing its value includes:

[0093] Using the aforementioned constraints as constraints, and aiming to maximize the value of the objective function, the objective function is solved.

[0094] In this embodiment, the first bottom dimension refers to the radius, diameter, and circumference of the inner bottom of the thin-walled platform. Simultaneously, the first bottom dimension is also the dimension of the bottom of the atomized material after it has been filled and flattened within the crucible. Correspondingly, the first top dimension can refer to the radius, diameter, and circumference of the top surface of the atomized material after a predetermined amount of atomized material has been filled and flattened within the crucible. The first top dimension and the first bottom dimension need to be set correspondingly; both can be either radius, diameter, or circumference.

[0095] In this embodiment, the preset ratio and preset taper can both be used to limit the size changes at the top and bottom ends of the atomized material, and can be set according to actual conditions.

[0096] Please see Figure 4 V is the volume of the predetermined amount of atomized material. h is the filling height of the predetermined amount of atomized material in the crucible; r1 is the radius of the bottom of the atomized material after it has been filled and flattened in the crucible; r2 is the first top dimension; R1 is the inner bottom radius of the crucible, i.e., the first bottom dimension, R1 = r1; R2 is the inner top radius of the crucible, i.e., the second top dimension. The dimensions of the crucible satisfy the constraint condition: r2 / r1 ≤ c1; where c1 is the preset ratio, and its value ranges from 1.4 to 1.5.

[0097] In this embodiment of the application, by setting the ratio of the first top dimension to the first bottom dimension to be no greater than a preset ratio, or by setting the taper of the atom to be no greater than a preset taper, the cross-sectional diameter of the atom can be prevented from changing significantly with height, which helps to improve the uniformity of the overall heating of the atom.

[0098] Optionally, the constraints may further include at least one of the following:

[0099] The predetermined amount of atomized material is filled to a height less than a preset height within the crucible; the preset height is determined based on the height to which the heating element surrounds the crucible.

[0100] The first bottom dimension is not greater than the second top dimension of a preset ratio; the second top dimension is the top dimension of the inner side of the crucible body.

[0101] In this embodiment of the application, the filling height is the height of the atomized material in the crucible after the predetermined amount of atomized material has been filled and flattened in the crucible.

[0102] In this embodiment of the application, the preset height is determined based on the wrapping height of the heating component around the crucible; specifically, the preset height is generally not greater than the wrapping height.

[0103] Please see Figure 4 , Figure 4 In this context, h0 represents the enclosing height of the heating element around the crucible, which is also the depth of the heating element; h represents the filling height of a predetermined amount of atomized material within the crucible. The dimensions of the crucible satisfy the constraint: h ≤ h0.

[0104] In this embodiment of the application, by constraining the filling height to be less than the preset height, the problem of poor heating consistency of the atomized material can be avoided by preventing the top of the atomized material from exceeding the heating area of ​​the heating component.

[0105] In this embodiment, the second top dimension refers to the diameter, radius, side length, and circumference of the inner top of the crucible body; correspondingly, the first bottom dimension refers to the radius, diameter, side length, and circumference of the inner bottom of the thin-walled platform body. The second top dimension and the first bottom dimension need to be set correspondingly; both can be either radius, diameter, side length, or circumference.

[0106] Please see Figure 4 , Figure 4 The crucible body described herein is roughly a thin-walled frustum with its opening facing upwards. R1 is the inner bottom radius of the crucible body, i.e., the first bottom dimension, R1 = r1; R2 is the inner top radius of the crucible body, i.e., the second top dimension. The dimensions of the crucible body satisfy the constraint condition: r1 = R1 ≤ c2·R2, where c2 is a preset ratio, which can be set according to actual conditions, for example, 50%.

[0107] In this embodiment of the application, by constraining the first bottom dimension to a second top dimension that is no larger than a preset ratio, it helps to improve the feasibility and rationality of structural assembly and reduce the assembly difficulty of related components.

[0108] Optionally, the heating component includes a metal sleeve disposed close to the lower part of the crucible body and a mesh resistance wire evenly arranged on the outer surface of the metal sleeve; the constraint conditions further include:

[0109] The first bottom dimension is not less than the minimum dimension threshold determined based on the minimum bottom dimension of the heating element.

[0110] In practical applications, due to limitations in the manufacturing process of the mesh resistance wire and the metal sleeve, the bottom dimension of the heating component may have a minimum value. This minimum bottom dimension can be the radius, diameter, side length, perimeter, or area of ​​the metal sleeve or the mesh resistance wire.

[0111] In this embodiment, the minimum size threshold is determined based on the minimum bottom size of the heating element; further, the minimum size threshold can be obtained based on the minimum bottom size of the heating element and the side wall thickness of the crucible; specifically, R1≥(r0-δ), where r0 is the minimum radius of the mesh resistance wire and δ is the side wall thickness of the crucible.

[0112] In this embodiment of the application, by constraining the first bottom dimension to be no less than a minimum dimension threshold determined based on the minimum bottom dimension of the heating component, the feasibility and rationality of the structural assembly are improved.

[0113] Optionally, the inner depth of the crucible and the second top dimension are predetermined based on the external dimensions of the electronic atomizing device; the second top dimension is the top dimension of the inner side of the crucible.

[0114] The step of maximizing the value of the objective function and solving the objective function to obtain the contour data of the crucible body includes:

[0115] Using the first bottom dimension of the crucible as the decision variable, and aiming to maximize the value of the objective function, the objective function is solved to obtain the value of the first bottom dimension.

[0116] In this embodiment, the inner depth of the crucible and the second top dimension are predetermined based on the external dimensions of the electronic atomizing device. For example, assuming the crucible is generally an upward-opening thin-walled frustum, and the length and width of the electronic atomizing device are Lt and Wt respectively, and the side wall thickness of the crucible is δ, then the second top dimension... In the formula, c3 is a structural design parameter, ranging from 0.55 to 0.65, used to limit the maximum diameter of the top surface of the frustum-shaped crucible to ensure the feasibility of assembling the crucible with the shell and the overall support. Generally, the second top dimension can be directly taken as the maximum value, i.e. The inner depth of the crucible body H ≤ c2×(Ht―H2)―δ d In the formula, c4 is another structural design parameter, ranging from 0.75 to 0.85, used to limit the maximum depth of the frustum-shaped crucible to ensure the overall balance of the crucible and other components in the height direction. When the crucible has other shapes, the process is similar to that of a thin-walled frustum, and will not be elaborated further here.

[0117] In this embodiment, the first bottom dimension is the inner bottom dimension of the crucible body, and it is also the bottom dimension of the atomized material. When the lower part of the crucible body is a thin-walled frustum, the first bottom dimension is the radius, diameter, circumference, etc., of the inner bottom of the thin-walled frustum. When the lower part of the crucible body is a thin-walled truncated pyramid, the first bottom dimension is the side length, circumference, inscribed circle diameter, or circumscribed circle diameter, etc., of the inner bottom of the thin-walled frustum.

[0118] In this embodiment of the application, the process of solving the objective function may refer to: using the first bottom dimension of the crucible as a decision variable, constructing a model based on the decision variable and the objective function; optimizing the model with the goal of maximizing the value of the objective function, and obtaining the first bottom dimension based on the optimal solution of the model.

[0119] In this embodiment, the inner depth of the crucible and the second top dimension are determined in advance based on the external dimensions of the electronic atomizing device. The first bottom dimension of the crucible is used as a decision variable, which reduces the number of decision variables involved in the objective function and helps to simplify the solution process of the objective function.

[0120] Optionally, the entire crucible body is generally a thin-walled frustum or a thin-walled prism with the opening facing upwards.

[0121] In this embodiment, not only is the lower part of the crucible body configured as a thin-walled frustum, but the entire crucible body can also be configured as a thin-walled frustum. The frustum-shaped crucible body slopes outward from bottom to top on its sides, facilitating installation and fixation during use, and improving the stability of the crucible body within the shell. The top of the crucible body is relatively large, facilitating the addition of a paste-like atomized material; the lower part of the crucible body is smaller, facilitating the filling and compaction of the paste-like atomized material within the crucible body.

[0122] Furthermore, the entire crucible body is a thin-walled frustum. For example, a square frustum, a hexagonal frustum, an octagonal frustum, a regular dodecagonal frustum, etc.

[0123] Optionally, the lower part of the crucible body is a thin-walled frustum or a thin-walled truncated cone, and the upper part of the crucible body is a hollow cylindrical structure connected to the frustum or truncated cone.

[0124] In the embodiments of this application, the hollow cylindrical structure may be a thin-shell cylindrical structure or a square cylindrical structure connected to the thin-walled frustum or thin-walled truncated cone. In some cases, the hollow cylindrical structure may also be set as another hollow frustum or frustum.

[0125] Optionally, the lower part of the crucible body is a hollow thin-walled platform with openings at the top and bottom, and the crucible body also includes a smooth curved surface structure connected to the hollow thin-walled platform.

[0126] In this embodiment of the application, the lower part of the crucible body is a hollow thin-walled platform with openings at the top and bottom, and the hollow thin-walled platform is a cylindrical structure with a cross-section that gradually decreases from top to bottom.

[0127] In this embodiment of the application, when the lower part of the crucible is a thin-walled frustum, the smooth curved surface structure can be a partially spherical structure, a partially ellipsoidal structure, a partially elliptic parabolic structure, a partially double-leaf hyperboloid structure, or other revolution curved surface structures that are coaxial with the thin-walled frustum.

[0128] The smooth curved surface structure can be smoothly connected to the hollow thin-walled platform.

[0129] The crucible body also includes a smooth curved surface structure connected to the hollow thin-walled platform.

[0130] Figure 7The diagram shown is a structural schematic of a crucible provided in an embodiment of this application. Figure 7 As shown, the entire crucible is roughly an upward-opening thin-walled frustum, and the smooth curved surface structure is a spherical structure tangent to the thin-walled frustum.

[0131] In this embodiment of the application, by setting the bottom of the crucible body to a smooth curved surface structure, it is beneficial to improve the uniformity of heating of the atomized material and effectively reduce the amount of paste residue after the equipment is used.

[0132] Exemplary device

[0133] The apparatus embodiments of this application can be used to execute the method embodiments of this application. For details not disclosed in the apparatus embodiments of this application, please refer to the apparatus embodiments of this application.

[0134] In addition to the above-described apparatus, embodiments of this application may also be an aerosol generating device, comprising:

[0135] shell;

[0136] A suction nozzle is located on the top of the housing;

[0137] And an aerosol generating device disposed inside the outer casing.

[0138] like Figure 1 and 2 As shown, the electronic atomizing device may include a housing 1, a mouthpiece 2, a top cover 3, a bottom cover 4, an outer decorative cover 5, an atomizing module 6, a main support 7, a battery 8, a circuit board 9, a charging port 10, and an atomizing module positioning component 11.

[0139] The electronic atomizing device has an upper and lower structure layout. From top to bottom, it consists of a mouthpiece 2, a top cover 3, an outer shell 1, a bottom cover 4, and an outer decorative cover 5. The top cover 3 and the bottom cover 4 are assembled inside the outer shell 1 and cooperate with the snap-fit ​​structure on the inner side of the outer shell 1.

[0140] The outer casing 1 may be equipped with a switch button 1-1 and an adjustment button 1-2; the top of the left and right sides of the outer casing 1 has assembly holes for the atomizing module positioning component 11. The nozzle 2 is equipped with an air inlet 2-1 for air intake and an air outlet 2-2 for inhaling aerosol.

[0141] Inside the entire smoking device, there is a main support frame 7, which is positioned and connected to the top cover 3 by a snap-fit ​​structure at the top, and is attached to the bottom cover 4 by screws through threaded posts corresponding to threaded holes. On the main support frame 7, from top to bottom, the atomizing module 6 and the electronic module are arranged sequentially. The electronic module includes a battery 8, a circuit board 9, and a charging port 10 located at the bottom of the circuit board 9. The charging port 10 extends to the bottom side of the entire device through the through hole in the middle of the bottom cover 4 and the outer decorative cover 5.

[0142] The atomizing module 6 consists of an airway silicone component 6-1, a shell 6-2, a support component 6-3, an aerogel insulation layer 6-4, and an aerosol generating device disposed inside the shell 6-2. Figure 2 (Not shown in the image). The main body consists of a shell 6-2, which houses the heating element assembly. A silicone air duct component 6-1 is fitted onto the top cylindrical thin-walled structure. The bottom cylindrical thin-walled structure has four openings corresponding to the contact points with the support component 6-3. An aerogel insulation layer 6-4 is arranged around the periphery of the shell 6-2 in the middle. A spring is located inside the atomizing module positioning component 11, positioned in a groove at the top of the shell 6-2. The spring's support ensures the atomizing module 6 is securely positioned within the device, preventing tilting or shifting, thus facilitating normal device operation.

[0143] like Figure 3 As shown, the aerosol generating device includes a crucible body 6-5 and a heating element 6-6; the aerosol generating device is the core component of the atomization module 6 and is located inside the casing.

[0144] The crucible body 6-5 is designed as a capless frustum-shaped cavity shell structure. The bottom of the inner crucible body is used to fill and support the paste-like atomized material, while the internal area above the paste-like atomized material constitutes the atomization zone, used for mixing the airflow with the paste-like atomized material to generate smoke. The heating element 6-6 is sleeved on the outer side of the crucible body 6-5. The electronic module supplies power to the heating element 6-6, making it a heat source that heats the crucible body 6-5. As a result, the paste-like atomized material inside the crucible body absorbs heat to the smoke-generating temperature, generating smoke for the user to inhale.

[0145] The nozzle 2 has an extension tube in its central interior, through which the air inlet 2-1 is directly connected. This extension tube passes through the central through-hole of the silicone airway component 6-1 and extends into the crucible body 6-5. The silicone airway component 6-1 and the extension tube form symmetrical outflow airways on the left and right sides, corresponding to the area between the inner side of the outer wall of the nozzle 2 and the outer side of the central tube. The overall airway structure and airflow are described as follows: When the user inhales, external airflow flows in through the air inlet 2-1, reaches the bottom area of ​​the crucible body 6-5 along the extension tube, mixes with the smoke generated after the paste-like atomized material is heated at the bottom of the crucible body 6-5 in the atomization zone, and reaches the inner side of the outer wall of the nozzle 2 along the silicone airway, finally flowing out from the air outlet 2-2.

[0146] Both the housing 6-2 and the bottom support 6-3 can be made of PEEK material, which has good mechanical properties, as well as good thermal insulation and temperature resistance, which is beneficial to the stable operation of the atomizing module 6 as a whole. Furthermore, the aerogel layer 6-4 fitted on the outer edge of the housing 6-2 can further reduce external heat exchange and heat diffusion, avoid adverse effects of the high-temperature heating element on external components, and at the same time improve the effective heat utilization rate of the heating element.
