[0002] The existing cartridges generally flavor the smoke by adding burst beads. The burst beads are generally coated with a hollow cotton core, and the burst beads can be broken by extruding the hollow cotton core to make the flavoring substances overflow. However, the material of the hollow cotton core is relatively soft, and the burst beads are prone to move in the hollow cotton core, which makes it difficult for the user to accurately pinch the burst beads at the first time when smoking, and when trying to pinch the burst beads for multiple times, the paper tube outside the cartridge will be deformed, affecting the user experience. In addition, the hollow cotton core also adsorbs a lot of smoke, which causes the smoke concentration to be low after the smoke generated by the smoke generating substrate is adsorbed, reducing the user's smoking experience.

[0034] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0035] In the description of the present application, unless explicitly defined and limited, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connection", "fixation" and the like should be understood in a broad sense, for example, "connection" can be fixed connection, or detachable connection, or integrally connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] In the description of the present application, it should be understood that the "upper", "lower" and other orientation words described in the embodiments of the present application are described with the angle shown in the drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "below", it can be directly connected to another element "on" or "below", or indirectly connected to another element "on" or "below" through an intermediate element.

[0037] As shown in FIGS. Figure 1 and Figure 2 The present application provides an aerosol generating article, which can be used in a smoking machine of a heat-not-burn cigarette. When the aerosol generating article is matched with a heating unit of the smoking machine, the heating unit can roast the aerosol generating article to release smoke from smoking components in the aerosol generating article, so as to be inhaled by a user. It can be understood that in order to improve the taste of smoke, a flavoring bead 212 is generally filled in the aerosol generating article. After the flavoring bead 212 is broken, the flavoring bead 212 can release flavor, which can improve the taste of smoke inhaled by the user after mixing with the smoke, thereby improving the user experience.

[0038] However, since the existing aerosol generating article generally adopts an empty cotton core to wrap the flavor adjusting beads 212, the flavor adjusting beads 212 are prone to move in the empty cotton core, which makes it difficult for the user to accurately squeeze the flavor adjusting beads 212 at the first time, and after multiple attempts to squeeze, the surface of the smoking body 2 is wrinkled, even broken or broken, which reduces the user experience.

[0039] Therefore, the aerosol generating article provided in the embodiments of the present application includes a filter 1 and a smoking body 2. The smoking body 2 is connected to the filter 1, and the end of the smoking body 2 away from the filter 1 can cooperate with the heating unit of the cigarette machine for baking. The smoking body 2 includes a flavoring part 21, and the flavoring part 21 includes a mesh tube 211 that clamps and fixes the flavor adjusting beads 212 through elastic deformation in the radial direction.

[0040] The side wall of the mesh tube 211 is a mesh structure, that is, a plurality of mesh holes 2111 are formed, so that the mesh tube 211 has a certain elastic stretching or shrinking function in the radial direction. When loading the flavor adjusting beads 212, the flavor adjusting beads 212 can be loaded from one end of the mesh tube 211 into the inside of the mesh tube 211. The mesh tube 211 can reliably clamp and fix the flavor adjusting beads 212 at the set position through its own elastic shrinking ability, so as to avoid the flavor adjusting beads 212 from moving in the mesh tube 211, thereby enabling the user to accurately squeeze the flavor adjusting beads 212, and improving the user experience.

[0041] It should be noted that the existing empty cotton core is a straight pipe-shaped hollow structure. Since the cotton material has the characteristics of softness and multiple fibers, it is difficult to load the flavor adjusting beads 212 from one end of the empty cotton core, and it is necessary to cut a notch in the side wall of the empty cotton core to partially expand the empty cotton core, so as to load the flavor adjusting beads 212 from the notch into the empty cotton core. However, this loading method of the flavor adjusting beads 212 is difficult to realize large-scale production, and the cutting process and the loading process require a large amount of manpower and material resources.

[0042] The aerosol generating article provided in the embodiments of the present application has a mesh tube 211 made of a non-cotton material. When the flavor adjusting beads 212 are loaded from one end of the mesh tube 211, the mesh tube 211 will not deform, such as collapse or wrinkle. Therefore, when loading the flavor adjusting beads 212, the mesh tube 211 does not need to be cut, thereby simplifying the process, facilitating the operation, and saving the investment cost of the aerosol generating article preparation process. In addition, since the mesh tube 211 does not use cotton material, the adsorption capacity of the mesh tube 211 for smoke is reduced, so that the user can inhale smoke with appropriate concentration, and the user's smoking experience is improved.

[0043] It should be noted that the flavor regulating beads 212 can be burst beads or hot melt beads or fragrance tallow columns. The burst beads can be broken by applying appropriate external force to release the flavor in the burst beads. The hot melt beads and the fragrance tallow columns include a layer of hot melt film layer, and the film layer is wrapped with flavor. When smoking, the film layer melts as the temperature rises, and the flavor can volatilize to form aroma.

[0044] Specifically, the material of the net tube 211 can be one of paper material, thermoplastic plastic or resin. The net tube 211 made of the paper material, thermoplastic plastic or resin material has certain toughness and elastic deformation ability, so that when the flavor regulating beads 212 are filled into the net tube 211, the net tube 211 will not be deformed such as collapse or wrinkle, ensuring the stability of the overall shape of the net tube 211. At the same time, the net tube 211 made of the paper material, thermoplastic plastic or resin material has weak ability to adsorb smoke, so that the smoke released by the aerosol generating article can be avoided to be adsorbed by the net tube 211 in large amount, ensuring that enough concentration of smoke can be inhaled by the user, and improving the smoking experience of the user.

[0045] In the embodiment, the material of the net tube 211 is preferably paper material. Specifically, the net tube 211 is woven by paper threads through a weaving process. The woven net tube 211 has certain elastic deformation ability, so that the net tube 211 can be slightly stretched or contracted in the radial direction. The elastic stretching of the net tube 211 in the radial direction can facilitate the loading of the flavor regulating beads 212, and the elastic contraction of the net tube 211 in the radial direction can facilitate the clamping and fixing of the flavor regulating beads 212.

[0046] The number of weaving needles of the net tube 211 can be 2, 3, 4, 5 or 6. In the embodiment, the number of weaving needles of the net tube 211 is preferably 6, so that the net tube 211 has high structural stability, and the net tube 211 will not collapse downward when placed vertically.

[0047] It can be understood that a plurality of mesh holes 2111 can be formed on the side wall of the net tube 211 during the weaving process, so as to facilitate the elastic stretching or contraction of the net tube 211 in the radial direction. The inner diameter of the net tube 211 is smaller than the outer diameter of the flavor regulating beads 212. During the process of filling the flavor regulating beads 212 into the net tube 211, the flavor regulating beads 212 can support the net tube 211, so that the net tube 211 is slightly elastically expanded in the radial direction. After the flavor regulating beads 212 are filled to the preset position, the net tube 211 can provide elastic force to clamp and position the flavor regulating beads 212 by the action of its elastic deformation, preventing the flavor regulating beads 212 from moving in the net tube 211.

[0048] As a specific implementation, the aerosol generating article further comprises a sleeve 3 and a support tube 4, the sleeve 3 is sleeved on the outside of the smoking body 2, and the support tube 4 is sleeved on the outside of the mesh tube 211, and the outer diameter of the mesh tube 211 is smaller than the inner diameter of the support tube 4.

[0049] The sleeve 3 can be a paper tube made of paper material, which is used to cover the circumferential surface of the smoking body 2 to prevent the particulate matter in the smoking body 2 from falling off. In addition, the support tube 4 and the mesh tube 211 are both arranged in the sleeve 3, and by making the outer diameter of the mesh tube 211 smaller than the inner diameter of the support tube 4, a deformation space can be provided for the radial stretching of the mesh tube 211, that is, when the mesh tube 211 is lifted by the flavoring beads 212, the diameter of the position on the mesh tube 211 where the flavoring beads 212 are loaded becomes larger, and the position on the mesh tube 211 where the diameter becomes larger can still be accommodated in the support tube 4, and the overall shape of the mesh tube is ensured to be stable by the constraint of the support tube 4, thereby ensuring that the aerosol generating article has a good appearance.

[0050] The outer diameter of the mesh tube 211 is 15% to 20% smaller than the inner diameter of the support tube 4. The flavoring beads 212 can make the diameter of the mesh tube 211 increase by 15% to 20% relative to the support tube 4, so that after the diameter of the mesh tube 211 changes due to the supporting action of the flavoring beads 212, the mesh tube 211 can still be accommodated in the support tube 4 without causing extrusion of the support tube 4.

[0051] As a specific implementation, the smoking body 2 further comprises an aerosol generating substrate 22 and a temperature regulating portion 23, both of which can be covered in the sleeve 3, the temperature regulating portion 23 is arranged between the flavoring portion 21 and the aerosol generating substrate 22, and the flavoring portion is arranged between the filter 1 and the temperature regulating portion 23. That is, the aerosol generating article provided by the embodiment of the present application comprises the flavoring portion 21, the temperature regulating portion 23 and the aerosol generating substrate 22 in sequence from the end close to the filter 1.

[0052] The aerosol generating substrate 22 can cooperate with the heating unit of the cigarette machine, and the heating unit can bake the aerosol generating substrate 22 to make the aerosol generating substrate 22 release smoke. The flavoring beads 212 of the flavoring portion 21 can release flavoring substances after being kneaded and broken, and the smoke and the flavoring substances can mix to form smoke with improved taste. However, since the heating temperature of the heating unit is generally above 280℃, the temperature of the smoke will be relatively high, and there is a risk of scalding if the user directly inhales the smoke. Therefore, in the embodiment, the smoke with improved taste can be cooled by the temperature regulating portion 23, the temperature regulating portion 23 can reduce the temperature of the high-temperature smoke to a temperature suitable for the user to inhale, and then the cooled smoke can be inhaled into the user's mouth.

[0053] Specifically, in the present embodiment, the temperature regulating portion 23 comprises konjac polysaccharide aerogel. The konjac polysaccharide aerogel can be filled into the sleeve 3 and located in the region between the flavoring portion 21 and the filter 1. The konjac polysaccharide can be gasified and endothermic after being heated, thereby achieving the effect of cooling. In addition, the konjac polysaccharide aerogel filled between the flavoring portion 21 and the filter 1 can also confine the smoking substrate in a set space, so as to ensure that the aerosol generating substrate 22 can be sufficiently roasted by the heating unit to release smoke, while isolating the particulate matter in the aerosol generating substrate 22 from diffusing to the filter 1.

[0054] As a specific implementation, the smoking body 2 further comprises a sealing portion 24 arranged at the end of the smoking body 2 away from the filter 1. The sealing portion 24 can prevent the contents of the aerosol generating substrate 22 from falling off, especially when the heating element of the smoking machine is inserted, which can press the original structure of the aerosol generating substrate 22. The sealing portion 24 can prevent the contents from falling into the smoking machine during the smoking process. At the same time, the sealing portion 24 can also play a role in preventing moisture during the transportation and storage of the aerosol generating article.

[0055] The contents can be tea particles, tea filaments, tea stems, etc. In the present embodiment, the aerosol generating substrate 22 comprises a tea particle layer and a tea stem layer. The tea particle layer is arranged at the side away from the filter 1, and the tea stem layer is arranged at the side close to the filter 1. The tea particle layer mainly plays a role in heating and releasing tea polyphenols, which are inhaled into the body during the smoking process, thereby achieving the effect of refreshing and relaxing. The tea stem layer mainly plays a role in adsorbing tar. In addition, the tea particle layer also contains smoking agents and flavoring ingredients to optimize the smoking experience.

[0056] The present application also provides an application of the aerosol generating article in a heat-not-burn cartridge and / or a cigarette. In the present embodiment, the aerosol generating article is preferably applied to a heat-not-burn cartridge. It can be understood that the heat-not-burn cartridge needs to be heated by a heat-not-burn smoking machine during use. The smoking machine is provided with a heating element (such as a heating sheet, etc.). The heating element can be a heating sheet or a heating rod. The heating sheet or the heating rod can be inserted into the aerosol generating substrate 22 of the aerosol generating article to roast the aerosol generating substrate 22, so that the aerosol generating substrate 22 releases smoke for the user to smoke. Of course, the structure of the present aerosol generating article can also be applied to traditional combustion cigarettes.

[0057] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various modifications and changes to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
