Description

Technical Field

[0001] This application relates to the field of aerosol technology, and in particular to an aerosol generating article. Background Technology

[0002] Heated non-combustible aerosol generators typically use an electric heating device to heat the solid smoke-generating medium within them at temperatures below 350°C, producing an aerosol for users to inhale. The aerosols produced by heated non-combustible aerosol generators contain relatively few harmful substances, thus reducing the harm to human health. Therefore, heated non-combustible aerosol generators can serve as a novel alternative to combustible cigarettes. However, traditional aerosol generators often suffer from drawbacks such as lower cleanliness and difficulty in stable aerosol release. Utility Model Content

[0003] One of the technical problems addressed by this application is how to improve the cleanliness of aerosol-generated products and the stability of aerosol release.

[0004] An aerosol-generating article, comprising:

[0005] Medium unit;

[0006] An air intake unit is disposed at one end of the medium unit. The air intake unit forms an air intake cavity. The air intake unit is provided with an air intake groove. The air intake groove extends from the side of the air intake unit away from the medium unit toward the medium unit by a predetermined length. The end of the air intake cavity away from the medium unit is arranged around the air intake groove. The air intake unit is also provided with an air intake hole that connects the air intake groove and the air intake cavity.

[0007] An air outlet unit is disposed at the other end of the medium unit away from the air inlet unit, and the air outlet unit forms an air outlet chamber that communicates with the air inlet chamber.

[0008] In one embodiment, the medium unit includes a medium body, which is an integrally formed solid. An air passage is formed inside the medium body, and the air passage connects the air inlet chamber and the air outlet chamber.

[0009] In one embodiment, the medium unit further includes an air inlet, an air outlet, and a sleeve. The sleeve is fitted over the medium body. The air inlet is connected to one end of the sleeve and abuts against the end of the medium body near the air inlet cavity. The air inlet has an air inlet channel that connects the air passage and the air inlet cavity. The air outlet is connected to the other end of the sleeve and abuts against the end of the medium body near the air outlet cavity. The air outlet has an air outlet channel that connects the air passage and the air outlet cavity.

[0010] In one embodiment, the air intake unit includes an air intake outer sleeve, an air intake inner sleeve, a first air intake support member, and a second air intake support member that surround the air intake cavity. The air intake outer sleeve is disposed on the medium unit and surrounds the air intake inner sleeve. The first air intake support member is connected between the ends of the air intake outer sleeve and the air intake inner sleeve that are away from the medium unit. The second air intake support member is connected to the end of the air intake inner sleeve that is close to the medium unit. The air intake inner sleeve and the second air intake support member form the air intake groove.

[0011] In one embodiment, at least one of the inner intake sleeve and the second intake support is provided with the intake hole.

[0012] In one embodiment,

[0013] From one end of the intake jacket closer to the medium unit to the other end farther from the medium unit, the cross-sectional dimension of the intake jacket decreases, and / or;

[0014] The cross-sectional dimension of the intake inner sleeve increases from the end closest to the medium unit to the end furthest from the medium unit.

[0015] In one embodiment, the air outlet unit includes an air outlet outer sleeve disposed on the medium unit and surrounding the air outlet cavity, wherein the end of the air outlet cavity away from the medium unit forms an open opening.

[0016] In one embodiment, the air outlet unit includes an outer air outlet sleeve, an inner air outlet sleeve, a first air outlet support member, and a second air outlet support member that surround the air outlet cavity. The outer air outlet sleeve is disposed on the medium unit and surrounds the inner air outlet sleeve. The first air outlet support member is connected between the outer air outlet sleeve and the inner air outlet sleeve at the ends away from the medium unit. The second air outlet support member is connected to the end of the inner air outlet sleeve near the medium unit. The inner air outlet sleeve and the second air outlet support member form an air outlet groove that communicates with the air outlet cavity.

[0017] In one embodiment,

[0018] At least one of the venting inner sleeve and the second venting support is provided with a venting hole, the venting hole connecting the venting cavity and the venting groove, and / or;

[0019] From one end of the vent sleeve closer to the medium unit to the other end farther from the medium unit, the cross-sectional dimension of the vent sleeve decreases, and / or;

[0020] The cross-sectional dimension of the venting inner sleeve increases from the end closest to the medium unit to the end furthest from the medium unit.

[0021] In one embodiment, a wrapping element is also included, which is simultaneously fitted onto the medium unit, the air inlet unit, and the air outlet unit.

[0022] One technical advantage of one embodiment of this application is that, given the inlet groove formed by the recess on the side of the inlet unit away from the medium unit, it can effectively prevent the liquid generated during the heating process of the medium unit from seeping outwards, and can also block solid impurities such as carbon ash from falling off, thereby improving the cleanliness of the aerosol-generated product. On the other hand, the inlet chamber can act as a buffer zone for air intake, reducing the frictional resistance of gas flow and thus improving gas flowability. This allows gas to quickly enter the inlet chamber through the inlet groove and the inlet, so that the gas carrying the aerosol can be quickly discharged from the outlet chamber for absorption by the user, thereby improving the stability of aerosol release.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] See Figure 1 , Figure 2 and Figure 3 An embodiment of this application provides an aerosol generating article 10 comprising a medium unit 100, an air inlet unit 200, and an air outlet unit 300. The air inlet unit 200 is disposed at one end of the medium unit 100, and the air outlet unit 300 is disposed at the other end of the medium unit 100 away from the air inlet unit 200, i.e., the medium unit 100 is located between the air inlet unit 200 and the air outlet unit 300. The air inlet unit 200 forms an air inlet cavity 240, and an air inlet groove 251 is recessed on the side of the air inlet unit 200 away from the medium unit 100. The air inlet groove 251 extends a certain length from the side of the air inlet unit 200 away from the medium unit 100 toward the medium unit 100. The end of the air inlet cavity 240 away from the medium unit 100 is disposed around the air inlet groove 251. An air inlet hole 252 is also provided on the air inlet unit 200, and the air inlet hole 252 connects the air inlet groove 251 and the air inlet cavity 240. The exhaust unit 300 forms an exhaust chamber 340, which is interconnected with the intake chamber 240. When the medium unit 100 is heated, it generates aerosol. External gas can enter the intake chamber 240 from the intake groove 251 through the intake hole 252. Then, the gas carries the aerosol from the intake chamber 240 through the inside of the medium unit 100 to the exhaust chamber 340. Finally, the aerosol is discharged from the exhaust chamber 340 to be absorbed by the user.

[0036] Given the design of the air inlet groove 251, it effectively prevents liquid generated during the heating process of the medium unit 100 from seeping outwards, and also blocks solid impurities such as carbon ash from falling off, thereby improving the cleanliness of the aerosol-generated product 10. On the other hand, the air inlet chamber 240 acts as a buffer zone for air intake, reducing the resistance along the gas flow path and improving gas flowability. This allows gas to quickly enter the air inlet chamber 240 through the air inlet groove 251 and air inlet hole 252, so that the gas carrying the aerosol can be quickly discharged from the air outlet chamber 340 for absorption by the user, thus improving the stability of aerosol release. Furthermore, the aerosol can be mixed and buffered within the air outlet chamber, and the air outlet chamber can lower the temperature of the aerosol, preventing excessively high aerosol temperatures from affecting the user experience.

[0037] See Figure 1 In some embodiments, the medium unit 100 includes a medium body 110, which is a monolithically formed solid. An air passage 111 is formed within the medium body 110, extending axially through the entire medium body 110. Therefore, the air passage 111 has openings on both end faces along the axial direction of the medium body 110, allowing the two ends of the air passage 111 to connect to the inlet chamber 240 and the outlet chamber 340, respectively. This allows gas in the inlet chamber 240 to enter the air passage 111 and carry aerosol into the outlet chamber 340. Therefore, by providing the air passage 111, the aerosol discharge rate can be further increased, thereby improving the stability of aerosol release. Multiple air passages 111 can be provided, spaced apart from each other.

[0038] See Figure 2 and Figure 4In some embodiments, the medium unit 100 further includes an air inlet 120, an air outlet 130, and a sleeve 140. The sleeve 140 may be generally cylindrical and sleeved outside the medium body 110. The air inlet 120 may be generally flat. The air inlet 120 is connected to the end of the sleeve 140 near the air inlet cavity 240, and the air inlet 120 abuts against the end of the medium body 110 near the air inlet cavity 240, such that the air inlet 120 is stacked on the end face of the medium body 110 near the air inlet cavity 240. The air outlet 130 may be generally flat. The air outlet 130 is connected to the end of the sleeve 140 near the air outlet cavity 340, and the air outlet 130 abuts against the end of the medium body 110 near the air outlet cavity 340, such that the air outlet 130 is stacked on the end face of the medium body 110 near the air outlet cavity 340. Both the air inlet 120 and the air outlet 130 can be perpendicularly connected to the sleeve 140, so that the sleeve 140 limits the medium 110 radially, and the medium 110 abuts against the air inlet 120 and the air outlet 130 axially, thus limiting the medium 110 axially. The air inlet unit 200 can be disposed on the air inlet 120, and the air outlet unit 300 can be disposed on the air outlet 130. By setting up the air inlet 120, air outlet 130, and sleeve 140, the outer diameter of the sleeve 140 remains constant as the medium 110 is gradually consumed, and the distance between the air inlet 120 and the air outlet 130 remains constant. This ensures that the axial and radial dimensions of the entire medium unit 100 remain constant, thereby improving the stability and reliability of the connection of the entire aerosol generating product 10. It also facilitates the unloading and smooth removal of the aerosol generating product 10 from other mechanisms after the medium 110 is completely consumed, preventing parts from falling off during the removal process and ensuring that the aerosol generating product 10 can be smoothly removed as a whole.

[0039] See Figure 2 and Figure 4 The sleeve 140 can be a single piece, or it can consist of two separate sections, one vertically connected to the air inlet 120 and the other vertically connected to the air outlet 130, thus facilitating the assembly of the entire medium unit 100. The air inlet 120 has an air inlet channel 121, which connects the air inlet chamber 240 and the air passage 111, allowing gas in the air inlet chamber 240 to enter the air passage 111 via the air inlet channel 121. The air outlet 130 has an air outlet channel 131, which connects the air outlet chamber 340 and the air passage 111, allowing gas in the air passage 111 to enter the air outlet chamber 340 for discharge.

[0040] See Figure 2 , Figure 3 and Figure 5 In some embodiments, the air intake unit 200 includes an air intake outer sleeve 210, an air intake inner sleeve 220, a first air intake support 231, and a second air intake support 232. The air intake outer sleeve 210, the air intake inner sleeve 220, the first air intake support 231, and the second air intake support 232 together form an air intake cavity 240. The air intake outer sleeve 210 is disposed on the medium unit 100 and surrounds the air intake inner sleeve 220. It can be understood that the air intake inner sleeve 220 is housed within the space enclosed by the air intake outer sleeve 210. The first air intake support 231 and the second air intake support 232 are spaced apart along the axial direction of the medium unit 100, such that the first air intake support 231 is farther away from the medium unit 100 than the second air intake support 232. The first intake support 231 is generally annular and connects the intake outer sleeve 210 and the intake inner sleeve 220 at the end furthest from the medium unit 100, such that the inner edge of the first intake support 231 is connected to the intake inner sleeve 220, and the outer edge of the first intake support 231 is connected to the intake outer sleeve 210. The second intake support 232 can be generally circular and is connected to the end of the intake inner sleeve 220 near the medium unit 100. The intake inner sleeve 220 and the second intake support 232 form an intake groove 251.

[0041] See Figure 2 , Figure 3 and Figure 5 In some embodiments, at least one of the inner intake sleeve 220 and the second intake support 232 is provided with an intake hole 252. For example, only the second intake support 232 is provided with an intake hole 252, and the center line of the intake hole 252 can coincide with the central axis of the medium unit 100. Alternatively, only the inner intake sleeve 220 is provided with an intake hole 252, and the number of intake holes 252 on the inner intake sleeve 220 is multiple, with the multiple intake holes 252 spaced apart circumferentially on the inner intake sleeve 220. Yet another example is that both the inner intake sleeve 220 and the second intake support 232 are provided with intake holes 252. When multiple intake holes 252 are provided on the inner intake sleeve 220, the intake path and intake coverage area can be reasonably increased, thereby improving the uniformity and smoothness of the airflow entering the intake chamber 240, and ultimately improving the stability of aerosol release.

[0042] See Figure 3In some embodiments, the cross-sectional dimension of the intake jacket 210 can gradually decrease from the end near the medium unit 100 to the end away from the medium unit 100. This makes the intake jacket 210 constricted, and as the medium 110 is consumed, the intake jacket 210 can act as a stop for the medium 110, thereby preventing changes in the overall size of the medium 110 and further enhancing the smoothness of airflow while maintaining uniform airflow. Therefore, the intake jacket 210 is generally conical, with a relatively larger cross-sectional dimension at the end near the medium unit 100 and a relatively larger cross-sectional dimension at the end away from the medium unit 100. The generatrix of the intake jacket 210 can be a straight line, which forms an acute angle with the central axis of the medium unit 100; the generatrix of the intake jacket 210 can also be a curve, such as a parabola. In other embodiments, the cross-sectional dimensions of the air intake jacket 210 can remain constant from the end of the air intake jacket 210 near the medium unit 100 to the end away from the medium unit 100. In this case, the air intake jacket 210 is cylindrical.

[0043] See Figure 3 In some embodiments, the cross-sectional dimension of the intake inner sleeve 220 can gradually increase from the end of the intake inner sleeve 220 near the medium unit 100 to the end away from the medium unit 100. The generatrix of the intake inner sleeve 220 can be a straight line, which is set at an acute angle to the central axis of the medium unit 100. This can reasonably improve the structural strength of the entire intake unit 200.

[0044] See Figure 1 In some embodiments, the air outlet unit 300 may only include an air outlet outer sleeve 310, which is disposed on the medium unit 100 and forms an air outlet cavity 340. The end of the air outlet cavity 340 away from the medium unit 100 forms an open opening. The air outlet outer sleeve 310 may be approximately cylindrical or approximately conical, that is, the cross-sectional area of ​​the air outlet outer sleeve 310 may gradually decrease from the end of the air outlet outer sleeve 310 near the medium unit 100 to the end away from the medium unit 100. This allows the air inlet outer sleeve 210 to act as a stop for the medium body 110, thereby preventing changes in the overall size of the medium body 110 and further enhancing the smoothness of the airflow while maintaining uniform airflow.

[0045] See Figure 2 and Figure 3In some embodiments, in addition to the outer outlet sleeve 310, the outlet unit 300 also includes an inner outlet sleeve 320, a first outlet support 331, and a second outlet support 332. The outer outlet sleeve 310, the inner outlet sleeve 320, the first outlet support 331, and the second outlet support 332 together form an outlet cavity 340. In this case, the outlet unit 300 and the inlet unit 200 can be structurally similar. The outer outlet sleeve 310 is disposed on the medium unit 100, and the outer outlet sleeve 310 surrounds the inner outlet sleeve 320. It can be understood that the inner outlet sleeve 320 is housed within the space enclosed by the outer outlet sleeve 310. The first outlet support 331 and the second outlet support 332 are spaced apart along the axial direction of the medium unit 100, such that the first outlet support 331 is farther away from the medium unit 100 than the second outlet support 332. The first venting support 331 is approximately annular and connects the outer venting sleeve 310 and the inner venting sleeve 320 at the end furthest from the medium unit 100, such that the inner edge of the first venting support 331 connects to the inner venting sleeve 320, and the outer edge of the first venting support 331 connects to the outer venting sleeve 310. The second venting support 332 can be approximately circular and connects to the end of the inner venting sleeve 320 closest to the medium unit 100. The inner venting sleeve 320 and the second venting support 332 form a venting groove 351. By providing the venting groove 351, the cleanliness of the aerosol-generated product 10 and the stability of aerosol release can also be improved.

[0046] See Figure 2 and Figure 3 In some embodiments, at least one of the inner outlet sleeve 320 and the second outlet support 332 is provided with an outlet hole 352. For example, only the second outlet support 332 is provided with an outlet hole 352, and the center line of the outlet hole 352 may coincide with the central axis of the medium unit 100. Alternatively, only the inner outlet sleeve 320 is provided with an outlet hole 352, and the number of outlet holes 352 on the inner outlet sleeve 320 is multiple, with the multiple outlet holes 352 spaced apart circumferentially on the inner outlet sleeve 320. Yet another example is that both the inner outlet sleeve 320 and the second outlet support 332 are provided with outlet holes 352. When multiple outlet holes 352 are provided on the inner outlet sleeve 320, the uniformity and smoothness of the airflow in the outlet chamber 340 can be improved, ultimately enhancing the stability of aerosol release.

[0047] See Figure 3In some embodiments, the cross-sectional dimension of the exhaust jacket 310 can gradually decrease from the end near the medium unit 100 to the end away from the medium unit 100. This makes the exhaust jacket 310 constricted, and as the medium 110 is consumed, the exhaust jacket 310 can act as a stop for the medium 110, thereby preventing changes in the overall size of the medium 110 and further enhancing the smoothness of the airflow while maintaining uniform airflow. Therefore, the exhaust jacket 310 is generally conical, with a relatively larger cross-sectional dimension at the end near the medium unit 100 and a relatively larger cross-sectional dimension at the end away from the medium unit 100. The generatrix of the exhaust jacket 310 can be a straight line, forming an acute angle with the central axis of the medium unit 100; the generatrix can also be a curve, such as a parabola. See reference. Figure 2 In other embodiments, the cross-sectional dimensions of the exhaust sleeve 310 can remain constant from the end of the exhaust sleeve 310 near the medium unit 100 to the end of the exhaust sleeve 310 away from the medium unit 100. In this case, the exhaust sleeve 310 is cylindrical.

[0048] See Figure 3 In some embodiments, the cross-sectional dimension of the inner sleeve 320 can gradually increase from the end of the inner sleeve 320 closest to the medium unit 100 to the end furthest from the medium unit 100. The generatrix of the inner sleeve 320 can be a straight line, which forms an acute angle with the central axis of the medium unit 100. This can reasonably improve the structural strength of the entire air outlet unit 300.

[0049] See Figure 1 In some embodiments, the aerosol generating article 10 further includes a wrapping element 400, which is simultaneously fitted onto the medium unit 100, the air inlet unit 200, and the air outlet unit 300. Therefore, through the wrapping and binding effect of the wrapping element 400, the medium unit 100, the air inlet unit 200, and the air outlet unit 300 can be connected to form a single unit. The wrapping element 400 can be made of aluminum foil or other materials with certain thermal conductivity. In other embodiments, the air inlet unit 200 and the air outlet unit 300 can be connected at opposite ends of the medium unit 100 by snap-fit ​​or adhesive bonding.

[0050] This application also provides an aerosol generating apparatus for heating the aforementioned aerosol generating article 10. The aerosol generating apparatus includes a housing, a heating chamber, and a nozzle. The heating chamber is provided with a heating element, and the nozzle is provided with an outlet channel that communicates with the heating chamber. In use, the aerosol generating article 10 is placed in the heating chamber. The heating element generates heat to heat the medium unit 100 of the aerosol generating article 10, thereby causing the medium unit 100 to atomize and form an aerosol that can be inhaled by the user, flowing out from the outlet channel of the nozzle.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
