Description

Technical Field

[0001] This application relates to the field of atomization technology, and more specifically, to an atomizer and an aerosol generating device. Background Technology

[0002] An aerosol generator is a small device that uses heat-not-burning (HNB) technology to act on an aerosol-generating matrix and produce aerosols. Currently, when the aerosol-generating product is inserted into the atomizer of the aerosol generator, the airflow design corresponding to the periphery of the aerosol-generating product is unreasonable. The airflow usually rushes directly into the inner cavity at the bottom of the atomizer and then rises into the aerosol-generating product. This results in a high temperature at the center of the heating element and a low temperature at the periphery, i.e., an uneven temperature field of the heating element. This leads to insufficient carbonization of the aerosol-generating product, resulting in a small amount of aerosol in the first puff. Utility Model Content

Within the projection plane of the unfolded side of the base, the multiple near-air inlets are arranged in a staggered array. In this array, rows intersect at an angle relative to columns. In a projection plane perpendicular to the length of the atomizer, the projections of the centers of the multiple air inlets and the projection of the center of the inner hole are connected by a line, and the included angle between adjacent lines is the same.

[0012] In some embodiments, the air inlet includes multiple sets, each set of air inlets being located at different heights on the side of the base. Compared to the end face of the second end, the set of air inlets closer to the end face of the second end has a larger diameter, and the set of air inlets farther away from the end face of the second end has a smaller diameter.

[0043] An aerosol generating device is a small device that uses heat-not-burning (HNB) technology to act on an aerosol generating matrix and produce aerosols. Currently, when an aerosol generating article is inserted into the atomizer of an aerosol generating device, the airflow design corresponding to the periphery of the article is unreasonable. The airflow typically rushes directly into the inner hole at the bottom of the atomizer and then upwards into the aerosol generating article, resulting in a high temperature at the center of the heating element and a low temperature around the periphery. This uneven temperature field leads to insufficient carbonization of the aerosol generating article, resulting in a small aerosol volume in the first puff. This makes it difficult to meet the atomizer's requirement for a large aerosol volume in the first puff. To solve this problem, this application provides an atomizer 100 (… Figures 1 to 3 (as shown) and an aerosol generating device 1000 having an atomizer 10 .... Figure 12 (As shown).

[0044] The aerosol generating device 1000 is a structure capable of generating aerosols by acting on an aerosol generating matrix through resistance heating, electromagnetic heating, microwave heating, laser irradiation, infrared light irradiation, ultrasound, or mechanical vibration. For example, the aerosol generating device generates aerosols by heating the aerosol generating product with infrared light irradiation. The aerosol generating product 3000 is used to be baked and heated to generate aerosols. The aerosol generating product 3000 includes an atomizing medium, which is an element that can generate aerosols after being heated. The atomizing medium can be atomized into fine particles by heating or ultrasonic vibration and mixed with air to form an aerosol. The atomizing medium can be in solid or liquid form. When the atomizing medium is all-solid, it can be prepared using processes such as rolling or thickening. It should be noted that in some embodiments, the atomizing medium can be a cylindrical structure similar to a cigarette, or a sheet-like, strip-like, or block-like structure. The aerosol can be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is typically liquid or solid at room temperature) as well as liquid droplets of gas and condensed vapor. Aerosol generating article 3000 insertion. Figure 1 In the case of the aerosol generating apparatus 1000 shown, the aerosol generating apparatus 1000 is capable of generating aerosols. The term "aerosol" as used herein encompasses the aerosol generated when the atomizing medium in the heated aerosol generating article 3000 is heated. In this application, the aerosol generating article 3000 includes a plug section 3001, a medium section 3003, a cooling section 3005, and a filter section 3005 connected in sequence. The plug section 3001 of the aerosol generating article 3000 is used to seal the medium storage area of ​​the aerosol generating article 3000. The plug section 3001 prevents dust, impurities, etc., from entering the medium section 3003, protecting the cleanliness and function of the internal components. The medium section 3003 of the aerosol generating article 3000 is the area where liquids or solids are converted into aerosols. The medium section 3003 converts liquids or solids into tiny particles to form aerosols through heating, ultrasonic vibration, or other physical methods. The cooling section 3005 of the aerosol generating product 3000 is used to reduce the temperature of the generated aerosol. The cooling section 3005 typically has a specific airflow channel (e.g., a corrugated structure) to regulate the aerosol's flow rate and distribution. By cooling, the cooling section 3005 reduces the risk of aerosol combustion or overheating, improving user safety. The filtration section 3005 of the aerosol generating product 3000 is responsible for filtering impurities from the aerosol. It absorbs or blocks condensate formed after the aerosol cools, preventing it from entering the user's mouth. Simultaneously, the filtration section 3005 adjusts the aerosol's flowability and mouthfeel, making it smoother and more pleasant, thereby reducing irritation and enhancing the user experience.

[0045] Please see Figures 1 to 3 The atomizer 100 of this application includes a heating element 30 and a loading element 40. The loading element 40 has a receiving cavity 401, in which the heating element 30 is housed, and together with the loading element 40, forms a loading cavity 403, which is used to load the aerosol generating article 3000. The loading element 40 includes a support 41 and a seat 43. The seat 43 includes a first end 431 and a second end 432, which are opposite each other. The first end 431 is an open end and is connected to the support 41. The second end 432 is a closed end. The seat 43 has an inner hole 433, and an air inlet 4341 is provided on the side 434 of the seat 43 near the second end 432. The inner hole 433 communicates with both the air inlet 4341 and the loading cavity 403. The air inlet 4341 is configured to allow external airflow to flow through and enter the inner hole 433, and to cause the airflow entering the inner hole 433 to exert a resultant force on the inner hole 433 to form a swirling flow.

[0046] Please see Figure 3 The heating element 30 is a component capable of generating heat energy and transferring it to the surrounding environment. In some embodiments, the heating element 30 may include a heating body 31, a heating layer 33, and a conductive element 35. The heating body 31 may be porous ceramic. In some embodiments, porous ceramic is typically prepared by mixing ceramic slurry with a pore-forming agent and then sintering it. The sintered ceramic body has a large number of micropores (not shown in the figure). Specifically, the heating body 31 is a hollow structure open at both ends, with a receiving cavity 37 extending through the opposite ends. The heating layer 33 is disposed on the heating body 31 and includes, but is not limited to, at least one of heating circuits, heating sheets, heating films, heating wires, and heating meshes. In the embodiments of this application, the heating layer 33 is a heating film disposed on the outer peripheral wall of the heating body 31. The conductive element 35 may be a conductive structure made of conductive materials such as metal or alloy. The conductive element 35 is disposed on the heating body 31 and electrically connected to the heating layer 33 and external circuitry for transmitting external electrical energy to the heating layer 33. When the conductive element 35 transfers electrical energy to the heating layer 33, the heating layer 33 can generate heat and atomize the aerosol-generating article 3000 through porous ceramic. Specifically, the conductive element 35 in this application can be connected to the battery assembly 200 ( Figure 13 (As shown) Electrical connection, thereby enabling the conductive element 35 to transfer electrical energy from the battery assembly 200 to the heating layer 33 to heat the heating layer 33.

[0047] Please see Figure 2The loading assembly 40 is an assembly for loading other components in the atomizer 100. In this application, the loading assembly 40 is used to load the heating assembly 30. Specifically, the loading assembly 40 has a receiving cavity 401, which is a spatial structure for loading the heating assembly 30. The heating assembly 30 and the loading assembly 40 together form a loading cavity 403, which is a spatial structure for loading the aerosol generation article 3000. The loading cavity 403 includes at least a portion of the receiving cavity 401 and a receiving cavity 37.

[0048] The loading assembly 40 includes a bracket 41 and a base 43. The bracket 41 is a component used to support other elements. The bracket 41 supports the heating element 30 and the aerosol generating product 3000. The shape and size of the bracket 41 are not limited, as long as it can accommodate the other elements and ensure stable installation within the housing 10 of the aerosol generating device 1000. The material of the bracket 41 can be metal or plastic, etc., where the metal bracket 41 has higher strength and wear resistance, while the plastic bracket 41 has better insulation performance and lower cost. Along the length L of the aerosol generating device 1000 (that is, along the length L of the atomizer 100), the bracket 41 includes two opposite ends, one end of which has an opening communicating with the outside. The base 43 is a component connected to the other end of the bracket 41, and the base 43 and the bracket 41 are connected to form a receiving cavity 401. The shape (outer contour shape) and size of the base 43 are also not limited, and the material of the base 43 can be metal or plastic, etc. The metal can be, but is not limited to, stainless steel, aluminum, copper, etc. The metal base 43 is corrosion-resistant and high-temperature resistant, making it suitable for applications requiring high strength and corrosion resistance; the plastic base 43, on the other hand, has better insulation properties and lower cost.

[0049] Along the length L of the atomizer 100, the base 43 includes a first end 431 and a second end 432, which are opposite each other. The first end 431 is an open end and is connected to the bracket 41. The second end 432 is a closed end. The base 43 has an inner hole 433, which is a spatial structure set inside the base 43. The shape of the cross-section of the inner hole 433 can be arbitrarily set, such as a circle, square, triangle, or other regular or irregular shape. In this document, the cross-section of all components is a plane intercepted by a plane perpendicular to the length L of the atomizer 100. In this application, only a circular cross-section of the inner hole 433 is used as an example for illustration. The depth of the inner hole 433 along the length L of the atomizer 100 is not limited, as long as it provides space for the inhaled fresh air to generate a swirling flow. An air inlet 4341 is provided on the side 434 of the base 43 near the second end 432. The air inlet 4341 penetrates the side 434 of the base 43 and serves as a channel for outside air to enter the inner hole 433. The shape of the air inlet 4341 can be arbitrarily set, and this application does not limit it. In the embodiments of this application, in the plane perpendicular to the length direction L of the atomizer 100, the projection of the cross-section of the air inlet 4341 is approximately a parallelogram, and the shape of the longitudinal section of the air inlet 4341 is approximately circular or elliptical. The longitudinal section of the air inlet 4341 is a cross-section obtained by a surface parallel to the peripheral side surface of the inner hole 433. In the extension direction of the central axis P1 of the air inlet 4341, the depth of the air inlet 4341 is not limited, as long as sufficient air can enter the inner hole 433 to fully carbonize the aerosol-generated product 3000.

[0050] Currently, air inlets are typically designed as multiple holes, each a straight hole (the extension direction of the central axis of the air inlet passes through the center of the inner hole). The fluid forces generated by the airflow entering the inner hole from the multiple straight holes cancel each other out, making the resultant fluid force negligible (less than a very small preset value). In this embodiment, the air inlet 4341 is configured such that the airflow entering the inner hole 433 exerts a resultant force on the inner hole 433 to form a swirling flow, meaning that the fluid forces generated by the airflow entering the inner hole 433 from the air inlet 4341 do not cancel each other out, and the resultant fluid force cannot be ignored (greater than the preset value).

[0051] Please combine Figure 11In the atomizer 100 of this application, the base 43 of the loading assembly 40 is provided with an inner hole 433 communicating with the loading cavity 403, and an air inlet 4341 communicating with the inner hole 433 is provided on the side 434 of the second end 432 of the base 43. The air inlet 4341 is configured to allow external airflow to flow through and enter the inner hole 433, and to cause the airflow entering the inner hole 433 to exert a resultant force on the inner hole 433 to form a swirling flow. That is, external fresh air enters along the air inlet 4341 on the outer periphery of the base 43. When the inner hole is 433, the airflow forms a fluid resultant force and can form a swirling flow at the bottom of the inner hole 433. The swirling flow rises continuously and enters the outer periphery of the aerosol generating product 3000. When the heating element 30 is heating, it is beneficial to make the temperature field of the heating element 30 uniform. The heat enters the outer periphery of the aerosol generating product 3000 preferentially through heat conduction or radiation heating. The aerosol generating product 3000 can be fully carbonized, thereby increasing the amount of aerosol in the first puff of the aerosol generating product 3000 drawn by the user.

[0052] Please see Figures 4 to 9 In some embodiments, in a first plane along the length direction L of the vertical atomizer 100, the projection of the inner hole 433 is circular, and the extension direction of the central axis P1 of the projection of the air inlet 4341 does not pass through the center of the projection of the inner hole 433.

[0053] As described above, air intakes are typically straight holes, meaning that in the first plane, the central axis of the projection of the air intake intersects the projection of the inner hole at a point, and the tangent line on the projection of the inner hole passing through this point is perpendicular to the central axis of the projection of the air intake. In this embodiment, the extension direction of the central axis P1 of the projection of the air intake 4341 not passing through the center of the projection of the inner hole 433 means that the tangent line on the projection of the inner hole 433 passing through this point is neither perpendicular to nor coincident with the central axis P1 of the projection of the air intake 4341, but intersects to form a certain angle.

[0054] Compared to a straight air inlet, the air inlet 4341 in this embodiment is an inclined hole. The inclined air inlet 4341 is an air intake channel. The extension direction of the air intake channel is not consistent with the radial P2 direction of the inner hole 433 passing through the above-mentioned intersection point. When fresh air enters the inner hole 433 through the air intake channel, it can flow along the outer periphery of the seat 43 and form a swirling flow at the bottom of the inner hole 433.

[0055] The formation of the swirling flow is one of the key design features. When external air enters the inner hole 433 through the inclined air inlet 4341, the air swirls at the bottom of the inner hole 433 due to the angle of the air inlet (air inlet 4341). This swirling flow not only evenly distributes the airflow but also drives the airflow around the outer periphery of the aerosol generating product 3000 during its ascent. When the heating element 30 is operating, the presence of the swirling flow helps to distribute heat more evenly around the outer periphery of the aerosol generating product 3000, avoiding localized overheating or uneven heating. The heat generated by the heating element 30 is preferentially transferred to the outer periphery of the aerosol generating product 3000 through heat conduction or radiation. This uniform heating method not only improves the aerosol generation efficiency but also significantly increases the amount of aerosol inhaled in the first breath, thereby enhancing the user experience. Furthermore, the continuous upward movement of the swirling flow also drives the airflow inside the aerosol generating product 3000, further promoting the uniform distribution and release of aerosols.

[0056] Please see Figure 10 In some other embodiments, in a second plane passing through the central axis P1 of the air inlet 4341 and perpendicular to the first plane, the extension direction of the central axis of the projection of the air inlet 4341 is not consistent with the radial direction P2 of the inner hole 433.

[0057] As mentioned above, air intakes are typically straight holes, meaning that the central axis of the projection of the air intake 4341 coincides with the radial direction of the inner hole in the second plane. In this embodiment, the discrepancy between the central axis of the projection of the air intake 4341 and the radial direction P2 of the inner hole 433 in the second plane means that the central axis of the projection of the air intake 4341 does not coincide with or parallel to the radial direction P2 of the inner hole 433, but rather intersects and forms a certain angle.

[0058] Compared to a straight air inlet, the projection of the air inlet 4341 in the second plane of this embodiment is also inclined. The inclined air inlet 4341 serves as an air intake channel. When fresh air enters the inner hole 433 through the air intake channel, it can also flow along the outer periphery of the base 43 and form a swirling flow at the bottom of the inner hole 433. This swirling flow not only evenly distributes the airflow but also drives the airflow within the outer periphery of the aerosol generating product 3000 during its upward movement. When the heating element 30 is working, the presence of the swirling flow helps to distribute heat more evenly around the outer periphery of the aerosol generating product 3000, avoiding localized overheating or uneven heating. The heat generated by the heating element 30 is preferentially transferred to the outer periphery of the aerosol generating product 3000 through heat conduction or radiation heating. This uniform heating method not only improves the aerosol generation efficiency but also significantly increases the amount of aerosol inhaled in the first breath, thereby enhancing the user experience. Similarly, the continuous upward movement of the vortex can also drive the airflow inside the aerosol generating product 3000, further promoting the uniform distribution and release of aerosols.

[0059] Please see Figures 4 to 9 In some embodiments, in a first plane along the length direction L of the vertical atomizer 100, one side of the projection of the air inlet 4341 is tangent to the projection of the inner hole 433, and the other side of the projection of the air inlet 4341 intersects the projection of the inner hole 433.

[0060] In the first plane, the projection of the air inlet 4341 has two sides, namely the first side S1 and the second side S2. The first side S1 is tangent to the projection of the inner hole 433, and the second side S2 intersects the projection of the inner hole 433.

[0061] One side S1 of the projection of the air inlet 4341 is tangent to the projection of the inner hole 433. This means that one side edge of the air inlet 4341 and the edge of the inner hole 433 are in contact on the projection plane, forming a smooth transition geometric relationship. This tangent design allows the airflow to flow more smoothly along the edge of the inner hole 433 when entering the inner hole 433, reducing airflow turbulence and energy loss.

[0062] Please also see Figures 4 to 9 The other side S2 of the projection of the air inlet 4341 intersects with the projection of the inner hole 433, meaning that the other edge of the air inlet 4341 intersects with the edge of the inner hole 433 on the projection plane. This intersecting design allows the airflow to undergo a certain angle change when entering the inner hole 433, thereby forming a vortex inside the inner hole 433. The formation of the vortex not only evenly distributes the airflow but also drives the airflow around the outer periphery of the aerosol generating product 3000 during the upward process, thus achieving a more uniform heat distribution when the heating element 30 is working.

[0063] This geometric design, combining tangency and intersection, ensures smooth airflow as it enters the inner hole 433, while also promoting swirling flow through angular variations. This design reduces localized overheating or uneven heating caused by uneven airflow, minimizing waste of the aerosol-generated product 3000. Of course, the first side S1 and the second side S2 can also intersect the projection of the inner hole 433; this is not a limitation.

[0064] Please see Figures 4 to 9 In some embodiments, the atomizer 100 has at least one air inlet 4341; when there are multiple air inlets 4341 (two or more), the multiple air inlets 4341 are evenly distributed around the center of the inner hole 433.

[0065] The number of air inlets 4341 is not limited; it can be 1, 2, 3, 4, 5, 6, 7, 8, or more. The only requirement is to ensure that the airflow can form a swirling flow when entering the inner hole 433, thereby achieving uniform heating of the outer periphery of the aerosol-generated product 3000 and efficient release of the aerosol.

[0066] Please see Figure 4 There can be four air inlets 4341, which are evenly distributed around the center of the inner hole 433. The even distribution of the air inlets 4341 ensures that the gas can flow into the inner hole 433 evenly and efficiently, promotes the formation of swirl, and thus improves the overall airflow efficiency and performance.

[0067] When there is only one air inlet 4341, the airflow entering the inner hole 433 tends to accumulate at the connection between the air inlet 4341 and the inner hole 433, resulting in less airflow distribution in other parts of the inner hole 433 and uneven airflow distribution within the inner hole 433. This embodiment designs multiple air inlets 4341, which on the one hand increases the airflow rate entering the inner hole 433; on the other hand, it allows external gas to enter the inner hole 433 from multiple connection points between the multiple air inlets 4341 and the inner hole 433, avoiding the problem of uneven airflow distribution within the inner hole 433 and forming a swirling flow. When the heating element 30 is working, the uniform distribution of the swirling flow ensures that heat is transferred more evenly to the entire surface of the aerosol generating product 3000, avoiding localized overheating or uneven heating.

[0068] In addition, when there is only one air inlet 4341, when the airflow enters the inner hole 433 through the air inlet 4341, it will cause the seat body 43 to be subjected to excessive force and cause shaking. In this embodiment, the number of air inlets 4341 is designed to be multiple, so that the airflow can enter the inner hole 433 from multiple directions, which can reduce the probability of shaking caused by excessive force on one part of the seat body 43.

[0069] Please see Figures 4 to 9 In some embodiments, the air inlet 4341 includes at least one group, each group including multiple air inlets 4341, and in each group of air inlets 4341, the central axis P1 of the multiple air inlets 4341 is located in the same plane in the length direction L of the atomizer 100.

[0070] The number of air inlets 4341 in each group can be 2, 3, 4, 5, 6, 7, 8, or more. Compared to the method of setting air inlets 4341 without grouping, the design in which the central axis P1 of multiple air inlets 4341 in each group is located in the same plane along the length L of the atomizer 100 makes it easier for the inhaled air to form a vortex at the bottom, and the speed at which the vortex is formed is faster. When the volume of inhaled airflow is equal, the fewer the number of air inlets 4341, the larger the diameter of the air inlets 4341 will be. An excessively large diameter may prevent the incoming air from forming a vortex, which will lead to uneven heating of the aerosol generating product 3000, resulting in insufficient heating of the aerosol generating product 3000 and failure to generate a large amount of aerosol.

[0071] The design of this embodiment enables each group of air inlets 4341 to form a ring-shaped air intake structure in space, ensuring that the airflow can enter the inner hole 433 evenly from multiple directions in the same plane, while ensuring that the airflow can form multi-directional swirling components in the same plane. These swirling components converge at the bottom of the inner hole 433 and form a stable swirling flow, thereby achieving a more uniform heat distribution and aerosol release during the aerosol generation process.

[0072] Please see Figure 5 In some embodiments, the air inlets 4341 include multiple sets, each set of air inlets 4341 being located at different heights on the side portion 434 of the base 43. Within the projection plane of the unfolded side portion 434 of the base 43, the multiple air inlets 4341 are arranged in a staggered array. In the array, rows and columns intersect perpendicularly.

[0073] The height is measured along the length L of the atomizer 100, relative to the distance from the end face of the second end 432. Since the central axes P1 of multiple air inlets 4341 in each group are all located in the same plane perpendicular to the length L of the atomizer 100, the different heights of each group of air inlets 4341 on the side 434 of the base 43 refer to the different distances between the same plane containing all the central axes P1 in each group of air inlets 4341 and the end face of the second end 432. In this application, the base 43 is a cylinder, and the projected surface of the unfolded side 434 of the base 43 is rectangular. The multiple air inlets 4341 are arranged in a staggered array, and in the array, the rows and columns intersect perpendicularly; that is, the array is a rectangular array.

[0074] Multiple sets of air inlets 4341 can be arranged in layers along the length L of the atomizer 100, with each set of air inlets 4341 located in a cross-sectional plane at a different height. This layered design can further enhance the uniformity of airflow distribution and the stability of the swirl. This application uses three sets of air inlets 4341 as an example for illustration. The three sets of air inlets 4341 are the first set of air inlets, the second set of air inlets, and the third set of air inlets. The first set of air inlets is located at the end face of the second end 432 closest to the base 43, and is used to form the initial swirl; the second set of air inlets can be located near the middle of the base 43, and is used to supplement the airflow and maintain the intensity of the swirl; the third set of air inlets can be located at the end face of the first end 431 closest to the base 43, and is used to optimize the aerosol release effect.

[0075] In the atomizer 100 of this application embodiment, each group of air inlets 4341 is located at different heights on the side 434 of the base 43. In the projection plane of the side 434 of the base 43 after it is unfolded, multiple air inlets 4341 are arranged in a rectangular array. This arrangement makes the air inlets 4341 on the base 43 look more regular. While ensuring the appearance of the base 43, it can also allow more air to be drawn in from the outside, providing enough air for the full carbonization of the subsequent aerosol product 3000.

[0076] Please see Figure 6 and Figure 7 In some embodiments, the air inlets 4341 include multiple sets, each set of air inlets 4341 being located at different heights on the side portion 434 of the base 43. Within the projection plane of the unfolded side portion 434 of the base 43, the multiple air inlets 4341 are arranged in a staggered array. In the array, rows intersect at an angle relative to columns. In the projection plane perpendicular to the length direction L of the atomizer 100, the projections of the centers of the multiple air inlets 4341 and the projections of the centers of the inner holes 433 are connected by lines, and the included angle α1 between adjacent connecting lines is the same.

[0077] The explanation of height is the same as before. In the projection plane of the unfolded side portion 434 of the base 43, the multiple near-intake holes 4341 are arranged in a crisscrossing array, also as before, and will not be repeated here. The multiple intake holes 4341 are arranged in a crisscrossing array, with rows intersecting columns at an angle. That is, although the multiple intake holes 4341 in this embodiment are not arranged in a matrix, they are arranged in a parallelogram array. This arrangement makes the intake holes 4341 on the base 43 look more regular, ensuring the aesthetic appearance of the base 43 while also allowing for a greater volume of air intake. In the projection plane along the length L of the vertical atomizer 100, the projections of the centers of the multiple intake holes 4341 and the center of the inner hole 433 are connected by lines, and the included angles between adjacent lines are the same. That is, in the parallelogram array, adjacent intake holes 4341 in the same column are equidistantly distributed. For example, in the projection plane along the I-angle, O1, O2 and O3 are the centers of the three sets of air inlets 4341, O is the center of the air inlet 433, the angle between the line OO1 and the line OO2 is α1, and the angle between the line OO2 and the line OO3 is also α1.

[0078] In this embodiment, the multiple sets of air inlets 4341 are not only arranged in layers along the length L of the atomizer 100, but also in layers along the circumference of the base 43. This layered design not only ensures the uniformity of airflow in the vertical direction of the inner hole 433, but also ensures the uniformity of airflow in the circumference of the inner hole 433, which can further enhance the uniformity of airflow distribution and the stability of swirl. This application uses three sets of air inlets 4341 as an example for explanation. The three sets of air inlets 4341 are the first set of air inlets, the second set of air inlets, and the third set of air inlets. Looking at the length L of the atomizer 100, the first, second, and third sets of air inlets are located at the bottom, middle, and top, respectively. Specifically, the first set of air inlets is positioned closest to the end face 432 of the base 43 to form the initial swirl; the second set of air inlets can be positioned near the middle of the base 43 to supplement the airflow and maintain the intensity of the swirl; and the third set of air inlets can be positioned closest to the end face 43 to optimize the aerosol release effect. Looking at the circumference of the base 43, the first, second, and third sets of air inlets are located at the right, middle, and left, respectively.

[0079] Please see Figure 8 and Figure 9 In some embodiments, the air inlet 4341 includes multiple sets, each set of air inlets 4341 is located at different heights on the side 434 of the seat 43. Compared with the end face of the second end 432, the set of air inlets 4341 closer to the end face of the second end 432 has a larger aperture, and the set of air inlets 4341 farther away from the end face of the second end 432 has a smaller aperture.

[0080] The diameter of each set of air inlets 4341 is related to its height. Compared to the end face of the second end 432, the set of air inlets 4341 closer to the end face of the second end 432 has a larger diameter; while the set of air inlets 4341 farther away from the end face of the second end 432 has a smaller diameter. This aperture design ensures that the airflow can be rationally distributed according to the heating requirements of the aerosol-generated product 3000 after entering the inner hole 433.

[0081] Specifically, the large-diameter air inlet 4341 near the end face of the second end 432 provides a larger airflow rate, which is used to form a strong vortex at the bottom of the inner hole 433. This strong vortex can drive the airflow at the bottom of the aerosol-generating product 3000, ensuring that its bottom can be fully heated and carbonized. At the same time, the design of the large-diameter air inlet 4341 can also increase the initial kinetic energy of the airflow, enabling the vortex to form quickly and rise steadily. Meanwhile, the small-diameter air inlet 4341 away from the end face of the second end 432 provides a smaller airflow rate, which is used to supplement the airflow in the middle and upper part of the inner hole 433 and maintain the intensity of the vortex. This small-diameter design can avoid excessive diffusion of the airflow, ensuring that the airflow can concentrate on the middle and upper surface of the aerosol-generating product 3000 during the rising process, thereby achieving uniform heating.

[0082] The design of the air inlet 4341 with a gradient aperture distribution enables the atomizer 100 to achieve optimized airflow distribution at different heights, ensuring that the entire surface of the aerosol-generated product 3000 can be uniformly heated.

[0083] Please see Figure 8 and Figure 9 Furthermore, in some embodiments, the diameter of the inner hole 433 is greater than or equal to 5.0 mm and less than or equal to 6.0 mm.

[0084] Specifically, the diameter of the inner hole 433 can be 5.0mm, 5.1mm, 5.2mm, 5.3mm, 5.4mm, 5.5mm, 5.6mm, 5.7mm, 5.8mm, 5.9mm, or 6.0mm. When the diameter of the inner hole 433 is less than 5mm, the small inner hole 433 cannot provide sufficient swirling space, and the airflow will cancel each other out, failing to form a swirling flow. When the diameter of the inner hole 433 is greater than 6mm, the force of the airflow entering through the air inlet 4341 may dissipate due to the excessively large diameter, failing to form a swirling flow. The heat from the heating element 30 cannot be evenly carried by the air to contact the aerosol generating product 3000, resulting in an uneven heating field of the heating element 30. The aerosol generating product 3000 cannot be heated evenly, leading to insufficient carbonization of the aerosol generating product 3000 and a small amount of aerosol generated during carbonization.

[0085] Therefore, the aperture of the inner hole 433 of the atomizer 100 is greater than or equal to 5 mm and less than or equal to 6 mm, which can make the airflow entering the inner hole 433 form a swirling flow, thereby making the heating field of the heating component 30 uniform, and the aerosol generating product 3000 is uniformly heated and fully carbonized, thus the aerosol generating product 3000 generates a larger volume of aerosol gas during carbonization.

[0086] Please see Figure 8 and Figure 9 Furthermore, in some embodiments, the diameter of the air inlet 4341 is greater than or equal to 0.3 mm and less than or equal to 0.9 mm.

[0087] Specifically, the diameter of the air inlet 4341 can be 0.30mm, 0.32mm, 0.40mm, 0.43mm, 0.50mm, 0.55mm, 0.60mm, 0.67mm, 0.80mm, 0.82mm, or 0.90mm. When the diameter of the air inlet 4341 is less than 0.3mm, the user needs a greater suction force when using the atomizer 100, and it cannot be guaranteed that enough air enters the atomizer 100 to quickly and evenly transfer the heat from the heating element 30 to contact the aerosol generating product 3000. When the diameter of the air inlet 4341 is greater than 0.9mm, the air entering through the air inlet 4341 may not form a vortex due to the excessively large diameter, which will result in insufficient carbonization of the aerosol generating product 3000 and a small amount of aerosol generated by the carbonization of the aerosol generating product 3000.

[0088] Therefore, the diameter of the air inlet 4341 is greater than or equal to 0.3 mm and less than or equal to 0.9 mm. On the one hand, this ensures that the atomizer 100 has a suitable suction resistance, so that the user will not have a poor experience due to excessive suction. On the other hand, the airflow entering the inner hole 433 from the air inlet 4341 can form a swirling flow, making the heating field of the heating component 30 uniform. The aerosol generating product 3000 is heated evenly and carbonized fully, resulting in a larger volume of aerosol generated by the carbonization of the aerosol generating product 3000.

[0089] Please see Figure 4 Furthermore, the end of the air intake 4341 facing away from the inner hole 433 is provided with a chamfer α2.

[0090] Compared to an air intake without chamfer α2, the chamfer α2 design smooths the edge of the air intake 4341 opening, reducing turbulence and resistance when airflow enters. Airflow can enter the air intake 4341 more smoothly through the chamfer α2, avoiding energy loss due to sharp edges. Simultaneously, the chamfer α2 guides airflow into the air intake 4341 in a more uniform manner, preventing airflow concentration on one side or in a localized area, thus ensuring a more stable vortex flow after entering the inner hole 433.

[0091] Furthermore, the chamfer α2 design allows for adjustment of the airflow entry angle, making it more aligned with the tilt direction of the air inlet 4341, thereby creating a stronger and more stable vortex at the bottom of the inner hole 433. This enhanced vortex contributes to the uniform heating and thorough carbonization of the aerosol-generating product 3000, resulting in the generation of more aerosols.

[0092] Please see Figures 4 to 6 In some embodiments, the diameter of the inner hole 433 is greater than or equal to 3 mm and less than or equal to 4 mm.

[0093] Specifically, the diameter of the inner hole 433 can be 3.0mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, or 4.0mm. When the diameter of the inner hole 433 is less than 3.0mm, the small inner hole 433 cannot provide sufficient swirling space, and the airflow will cancel each other out and fail to form a swirling flow. When the diameter of the inner hole 433 is greater than 4.0mm, the force of the airflow entering through the air inlet 4341 may dissipate due to the excessively large diameter, and a swirling flow may not be formed. The heat from the heating element 30 cannot be evenly carried by the air to contact the aerosol generating product 3000. This will cause the heating field of the heating element 30 to be uneven, and the aerosol generating product 3000 will not be heated evenly, resulting in insufficient carbonization of the aerosol generating product 3000 and a small amount of aerosol generated by the carbonization of the aerosol generating product 3000.

[0094] Therefore, the aperture value of the inner hole 433 of the atomizer 100 is greater than or equal to 3.0 mm and less than or equal to 4.0 mm, which can make the airflow entering the inner hole 433 form a swirling flow, thereby making the heating field of the heating component 30 uniform, and the aerosol generating product 3000 is uniformly heated and fully carbonized, thereby making the aerosol generating product 3000 carbonized and generating a larger volume of aerosol gas.

[0095] Please see Figure 6 Furthermore, in some embodiments, the diameter of the air inlet 4341 is greater than or equal to 0.3 mm and less than or equal to 0.9 mm.

[0096] Specifically, the diameter of the air inlet 4341 can be 0.30mm, 0.32mm, 0.40mm, 0.43mm, 0.50mm, 0.55mm, 0.60mm, 0.67mm, 0.80mm, 0.82mm, or 0.90mm. When the diameter of the air inlet 4341 is less than 0.3mm, the user needs a greater suction force when using the atomizer 100, and it cannot be guaranteed that enough air enters the atomizer 100 to quickly and evenly transfer the heat from the heating element 30 to contact the aerosol generating product 3000. When the diameter of the air inlet 4341 is greater than 0.9mm, the air entering through the air inlet 4341 may not form a vortex due to the excessively large diameter, which will result in insufficient carbonization of the aerosol generating product 3000 and a small amount of aerosol generated by the carbonization of the aerosol generating product 3000.

[0097] Therefore, the diameter of the air inlet 4341 is greater than or equal to 0.3 mm and less than or equal to 0.9 mm. On the one hand, this ensures that the atomizer 100 has a suitable suction resistance, so that the user will not have a poor experience due to excessive suction. On the other hand, the airflow entering the inner hole 433 from the air inlet 4341 can form a swirling flow, making the heating field of the heating component 30 uniform. The aerosol generating product 3000 is heated evenly and carbonized fully, resulting in a larger volume of aerosol generated by the carbonization of the aerosol generating product 3000.

[0098] Please see Figure 6 Furthermore, the end of the air inlet 4341 facing away from the inner hole 433 is provided with a chamfer α2. Compared to an air inlet without a chamfer α2, the chamfer α2 design can smooth the edge of the opening of the air inlet 4341, reducing turbulence and resistance when the airflow enters. The airflow can enter the air inlet 4341 more smoothly when passing through the chamfer α2, avoiding energy loss caused by sharp edges; at the same time, the chamfer α2 can guide the airflow into the air inlet 4341 in a more uniform manner, avoiding the airflow from concentrating on one side or in a local area, thereby ensuring that the airflow can form a more stable vortex after entering the inner hole 433.

[0099] Furthermore, the chamfer α2 design allows for adjustment of the airflow entry angle, making it more aligned with the tilt direction of the air inlet 4341, thereby creating a stronger and more stable vortex at the bottom of the inner hole 433. This enhanced vortex contributes to the uniform heating and thorough carbonization of the aerosol-generating product 3000, resulting in the generation of more aerosols.

[0100] Please see Figure 5 , Figure 8 , Figure 9Furthermore, in some embodiments, the spacing between adjacent air inlets 4341 along the length L of the atomizer 100 is greater than or equal to 0.60 mm and less than or equal to 1.20 mm.

[0101] Specifically, the spacing between adjacent air inlets 4341 can be 0.60mm, 0.61mm, 0.65mm, 0.68mm, 0.70mm, 0.80mm, 0.90mm, 0.98mm, 1.00mm, 1.10mm, or 1.20mm. When the spacing between adjacent air inlets 4341 is less than 0.60mm, it will cause mutual interference between the incoming airflows, reducing the swirling effect. At the same time, when the spacing between adjacent air inlets 4341 is less than 0.60mm, it may weaken the mechanical strength of the base 43, thereby increasing the risk of damage to the base 43. When the spacing between adjacent air inlets 4341 is greater than 1.20mm, it will cause uneven distribution of the incoming airflow, reducing the atomization efficiency. When the spacing between adjacent air inlets 4341 is greater than 1.20mm, it may increase the volume of the base 43, making it inconvenient for users to carry.

[0102] Therefore, the spacing between adjacent air inlets 4341 is greater than or equal to 0.60 mm and less than or equal to 1.20 mm. On the one hand, this ensures that the atomizer 100 is not affected by the mutual interference between the incoming airflows and has a suitable atomization effect; on the other hand, it helps to improve the portability of the atomizer 100.

[0103] The connection between the bracket 41 and the base 43 can be either detachable or non-detachable. Detachable connections include threaded connections, snap-fit ​​connections, or a combination of both. Non-detachable connections include welding, adhesive bonding, integral molding, or any combination of the three.

[0104] Please see Figure 2 and Figure 3 In some embodiments, the bracket 41 is provided with a first connecting portion 411. The seat 43 includes a first section 435 and a second section 436, with an inner hole 433 and an air inlet 4341 disposed in the first section 435. The second section 436 is connected to the first section 435 and is provided with a receiving hole 4361. The loading cavity 403 includes the receiving hole 4361, which is used to load a portion of the aerosol generating product 3000 (a plug section 3001 and a portion of the plug section 3001 and the medium section 3003). The diameter of the receiving hole 4361 is larger than the diameter of the inner hole 433. The side portion 434 of the second section 436 is provided with a second connecting portion 4363. The first connecting portion 411 and the second connecting portion 4363 cooperate to connect the first end 431 of the seat 43 to the bracket 41.

[0105] The first connecting part 411 is a component on the bracket 41 for connecting to the base 43, and the second connecting part 4363 is a component on the base 43 for connecting to the bracket 41. In some examples, the first connecting part 411 is a locking block, and the second connecting part 4363 is a locking hole. In other examples, the first connecting part 411 is a locking hole, and the second connecting part 4363 is a locking block. Figure 2 (As shown). When the locking block is engaged in the locking hole, the first end 431 of the base 43 can be connected to the bracket 41; when the locking block is disengaged from the locking hole, the first end 431 of the base 43 can be separated from the bracket 41, thus achieving a detachable connection between the bracket 41 and the base 43 through a locking connection. This connection method not only simplifies the assembly and disassembly process, but also ensures a firm connection between the base 43 and the bracket 41, thereby enhancing the stability of the entire atomizer 100.

[0106] The base 43 comprises two sections, each with a specific function. The first section 435 of the base 43 is provided with an inner hole 433 and an air inlet 4341 to ensure that a large amount of fresh external air can enter smoothly. After the air enters the inner hole 433 through the air inlet 4341, a swirling flow is formed at the bottom of the inner hole 433. The formation of this swirling flow is a key step in the aerosol generation process, which enables the air to fully contact the heating element 30, thereby uniformly heating the aerosol-generated product 3000 and ensuring the efficiency and quality of aerosol generation.

[0107] The second section 436 of the base 43 is provided with a receiving hole 4361 for accommodating and fixing other key components, such as the heating element 30 and the aerosol generating product 3000. The side 434 of the second section 436 of the base 43 is provided with a second connecting part 4363, which cooperates with the first connecting part 411 of the base 43 to form a stable connection structure.

[0108] Please see Figure 2 and Figure 3 In some embodiments, the receiving hole 4361 is a stepped hole; the atomizer 100 also includes a sealing member 50 and a heat insulation member 70. The sealing member 50 is disposed on the stepped surface of the stepped hole, and in the radial direction P2 of the receiving hole 4361, the sealing member 50 is located between the second segment 436 and the heating element 31 of the heating assembly 30. The heat insulation member 70 is housed in the receiving cavity 401, and in the longitudinal direction L of the atomizer 100, the heat insulation member 70 is located between the support 41 and the heating assembly 30.

[0109] The atomizer 100's receiving hole 4361 is designed with a stepped hole structure, which has several advantages. First, the stepped hole shape can better adapt to the size and shape of the aerosol generating product 3000, making it more stable when inserted and preventing loosening or displacement from affecting the aerosol generation effect. Second, the stepped hole design facilitates full contact between the aerosol generating product 3000 and the heating element 30. Through the stepped hole's hierarchical structure, the aerosol generating product 3000 can fit more tightly against the heating element 30, ensuring uniform heat transfer, thereby improving the aerosol generation efficiency and quality.

[0110] A seal 50 is provided between the second section 436 of the base 43 and the heating element 31 of the heating assembly 30. The seal 50 is a component used to prevent fluid or gas leakage, effectively preventing external impurities such as dust and moisture from entering the atomizer 100. The seal 50 can be made of rubber, engineering plastics, etc. Rubber seals 50 have good elasticity and resilience, suitable for applications with high-frequency vibration and impact loads, while engineering plastic seals 50 have good high-temperature and high-pressure resistance. The seal 50 not only prevents leakage of gas or liquid generated during aerosol generation but also effectively isolates external air interference, ensuring the purity of the aerosol generation environment. The seal 50 is typically made of high-temperature resistant, corrosion-resistant, and elastic materials, requiring good sealing and durability. Since the heating assembly 30 generates high temperatures during operation, the seal 50 needs to maintain shape stability under high-temperature conditions while ensuring tight contact with the heating assembly 30.

[0111] The heat insulation component 70 is a device used to reduce heat transfer and is widely used in various scenarios requiring heat insulation. The heat insulation component 70 is typically made of materials such as ceramic fiber or metal heat insulation plates, effectively resisting high temperatures and reducing heat conduction, preventing damage to other components of the atomizer 100 due to excessive heat. In this application, the heat insulation component 70 in the atomizer 100 is positioned between the bracket 41 and the heating element 30. Its main function is to block the high temperature generated by the heating element 30 from being transferred to the outside (housing 10), thereby preventing the user from being burned by contact with the housing 10 during operation. The material of the heat insulation component 70 needs to possess excellent heat insulation performance and high temperature resistance, while also having a certain degree of mechanical strength and durability.

[0112] Please see Figure 12 and Figure 13 This application also provides an aerosol generating device 1000. The aerosol generating device 1000 includes a battery assembly 200 and an atomizer 100 according to any of the above embodiments. The battery assembly 200 is electrically connected to the atomizer 100.

[0113] Specifically, the battery assembly 200 is electrically connected to the atomizer 100 to provide power to electronic components such as the heating element 30 in the atomizer 100, so as to ensure that the atomizer 100 can work normally.

[0114] In the aerosol generating apparatus 1000 of this application, the base 43 of the loading assembly 40 is provided with an inner hole 433 communicating with the loading cavity 403, and an air inlet 4341 communicating with the inner hole 433 is provided on the side 434 of the second end 432 of the base 43. The air inlet 4341 is configured to allow external airflow to flow through and enter the inner hole 433, and to cause the airflow entering the inner hole 433 to exert a resultant force on the inner hole 433 to form a swirling flow, that is, the external fresh air flows along the outer periphery of the base 43. When the air inlet 4341 enters the inner hole 433, the airflow forms a fluid resultant force and can form a swirling flow at the bottom of the inner hole 433. The swirling flow rises continuously and enters the outer periphery of the aerosol generating product 3000. When the heating element 30 is heating, it is beneficial to the uniformity of the temperature field of the heating element 30. The heat enters the outer periphery of the aerosol generating product 3000 preferentially through heat conduction or radiation heating, and the aerosol generating product 3000 can be fully carbonized, thereby increasing the amount of aerosol in the first inlet.
