Description

Technical Field

[0001] This invention relates to an atomizing core, aerosol cartridge, and atomizing module, and particularly to an atomizing core, aerosol cartridge, and atomizing module for generating aerosols by electric heating in applications such as atomization of nicotine solutions, fragrances, and pharmaceutical solutions. Background Technology

[0002] Atomization technology is widely used in fields such as electronic nicotine delivery systems. Its principle is that when electricity is applied, the atomizing core heats up, atomizing the liquid on its liquid-conducting element. In aerosol cartridges, the atomizing core with axial through-holes is typically positioned parallel to the airflow, meaning the airflow passes through the axial through-holes. This arrangement allows the airflow to mix thoroughly with the vapor generated on the inner surface of the axial through-holes, resulting in a better taste.

[0003] In applications requiring high atomization, atomizing cores with axial through-holes typically include components such as a resistive mesh, an inner layer of liquid-guiding cotton, an inner metal tube (also called an inner metal support), an outer layer of liquid-guiding non-woven fabric, and an atomizing core shell. The inner layer of liquid-guiding cotton is usually composed of multiple layers of non-woven fabric and is fixed within the inner metal tube. The outer layer of liquid-guiding non-woven fabric is wrapped around the outer circumference of the inner metal tube and fixed between the inner metal tube and the atomizing core shell. Liquid-guiding through-holes are provided on the peripheral walls of the inner metal tube and the atomizing core shell to allow liquid in the aerosol cartridge to permeate through these holes into the outer and inner liquid-guiding non-woven fabrics. Because the inner metal tube separates the inner and outer liquid-guiding cotton, the outer layer cannot fully contact the inner layer, reducing the efficiency of liquid transfer from the outer to the inner layer. The presence of the inner metal tube also significantly reduces the channel area for liquid flow between the inner and outer liquid-guiding materials. These problems usually lead to insufficient liquid supply to the inner liquid-guiding cotton during atomization, resulting in excessively high temperature and damage to the inner liquid-guiding cotton during heating. In severe cases, it can cause carbonization of the surface of the inner liquid-guiding cotton in contact with the resistor mesh, resulting in a decrease in flavor and a significant reduction in the life of the atomizer core. Summary of the Invention

The outer liquid guiding tube comprises a tubular porous material integrally formed by fiber bonding; the resistive mesh sheet is rolled into a cylindrical shape, but the two ends of the resistive mesh sheet are arranged opposite each other with a gap; the inner liquid guiding cotton layer is composed of multiple layers of non-woven fabric rolled into a cylindrical shape.

[0005] Furthermore, the outer liquid guiding tube is made of two-component fiber bonded together.

[0006] Furthermore, the porosity of the outer liquid guiding tube wall is 20% to 95%.

[0007] Furthermore, the porosity of the outer liquid guiding tube wall is 70% to 95%.

[0008] Furthermore, the two ends of the resistor mesh in the circumferential direction are located on both sides of the seam of the inner liquid-conducting cotton that is rolled into a cylinder.

[0009] Furthermore, the atomizing core also includes an atomizing core center rod, which passes through the axial through hole of the atomizing core and is wrapped by the resistive mesh and the inner liquid-guiding cotton.

[0010] Furthermore, the atomizing core also includes an atomizing core housing, and the outer peripheral walls of both ends of the outer liquid guide tube are attached to the inner peripheral wall of the atomizing core housing.

[0011] The present invention also provides an aerosol bullet, wherein the aerosol bullet includes at least the atomizing core described in any one of the above claims.

[0012] Furthermore, the aerosol bullet also includes a liquid storage element for supplying liquid to the atomizing core, a buffer body disposed below the liquid storage element, and a liquid recovery element. One end of the liquid recovery element is connected to the liquid storage element, and the other end is connected to the buffer body. The end of the liquid recovery element connected to the buffer body partially compresses the buffer body. The liquid recovery element includes a sleeve and a core inserted into the sleeve. No axial through-hole is provided between the sleeve and the core, or within the core. Alternatively, at least one first through-hole axially penetrating the core is provided between the sleeve and the core, or within the core. The first through-hole is blocked by the buffer body, and the liquid recovery element communicates with the external atmosphere through the buffer body.

[0013] Furthermore, the liquid recovery element also includes a buffer tube, the buffer tube including at least one second through hole axially penetrating the buffer tube, the buffer tube communicating with the sleeve, the second through hole communicating with the core, and one end of the liquid recovery element having the second through hole communicating with the liquid storage element.

[0014] Furthermore, the aerosol bullet includes one or more liquid recovery elements.

[0015] Furthermore, the aerosol bullet includes an aerosol bullet shell, the aerosol bullet shell forming a cavity with an opening at the bottom, the top of the aerosol bullet shell extending into the cavity to form a liquid storage element through hole, the liquid storage element through hole also serving as an aerosol channel, and the inner peripheral wall of the outer liquid guide tube of the atomizing core covering the outer peripheral wall of the connection port at the lower part of the aerosol channel.

[0016] Furthermore, the aerosol bullet also includes an inner tube of the airway that is attached to the inner peripheral wall of the aerosol channel.

[0017] Furthermore, the lower end of the airway inner tube abuts against the inner liquid-guiding cotton of the atomizing core.

[0018] Furthermore, the aerosol bullet also includes a second housing base disposed at the bottom of the aerosol bullet housing, a first housing base disposed inside the aerosol bullet housing and spaced apart from the second housing base, a buffer chamber disposed between the first housing base and the second housing base, and a liquid storage element disposed between the aerosol bullet housing and the first housing base. The middle part of the first housing base protrudes toward the aerosol channel to form an atomizing core assembly port, and the inner peripheral wall of the outer liquid guide tube of the atomizing core covers the outer peripheral wall of the atomizing core assembly port.

[0019] Furthermore, the aerosol bullet also includes a porous liquid reservoir located at the bottom of the liquid reservoir element and covering the outer periphery of the atomizing core.

[0020] The present invention also provides an atomizing module, wherein the atomizing module includes at least the atomizing core described in any one of the above claims.

[0021] Furthermore, the atomizing module also includes a second housing base disposed at the bottom of the atomizing module, and a first housing base disposed above the second housing base and spaced apart from the second housing base. The middle of the first housing base protrudes upward to form an atomizing core assembly port, and the inner peripheral wall of the outer liquid guide tube of the atomizing core is attached to the outer peripheral wall of the atomizing core assembly port.

[0022] Furthermore, the atomizing module also includes a wire mounting hole disposed at the bottom of the first housing base, an electrode mounted on the second housing base, a wire of the atomizing core passing through the atomizing core assembly port and inserted into the wire mounting hole, and the upper part of the electrode being inserted into the wire mounting hole and connected to the wire.

[0023] According to the atomizing core of the present invention, the inner liquid-guiding cotton is directly fixed inside the outer liquid-guiding tube integrally formed by fiber bonding, eliminating the inner steel tube. This allows for full contact between the inner and outer liquid-guiding materials and significantly increases the direct contact area between them. Therefore, it greatly improves the efficiency of liquid transfer from the outer liquid-guiding material to the inner liquid-guiding material in the atomizing core, ensuring sufficient liquid supply to the inner liquid-guiding cotton. This, in turn, helps to improve the aerosol taste and significantly extend the life of the atomizing core.

[0024] The atomizing core, aerosol cartridge, and atomizing module of the present invention are suitable for atomizing various liquids, such as nicotine solutions, fragrances, and pharmaceutical solutions.

[0043] First Embodiment

[0044] Figure 1 This is a schematic diagram of the longitudinal section of an atomizing core according to a first embodiment of the present invention; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the atomizer core at point AA.

[0045] like Figure 1 and Figure 2 As shown, an atomizing core 930 according to a first embodiment of the present invention includes an integrally formed outer liquid guiding tube 9321, an inner liquid guiding cotton 9322 that is attached to the inner peripheral wall of the outer liquid guiding tube 9321 and rolled into a cylindrical shape, a resistive mesh 931 that is attached to the inner peripheral wall of the inner liquid guiding cotton 9322, and an atomizing core through hole 9328 that axially penetrates the atomizing core 930. The outer liquid guiding tube 9321 includes a tubular porous material integrally formed by fiber bonding; the resistive mesh 931 is rolled into a cylindrical shape, but the two ends of the resistive mesh 931 are arranged opposite to each other in the circumferential direction and there is a gap; the inner liquid guiding cotton 9322 is made of multiple layers of non-woven fabric rolled into a cylindrical shape.

[0046] In other words, in this invention, the two ends of the resistor mesh 931 in the circumferential direction do not contact each other.

[0047] In this invention, the outer liquid guiding tube 9321 comprises a tubular porous material integrally formed by fiber bonding. The fineness of the fibers is preferably in the range of 1.5 denier to 100 denier, such as 1.5 denier, 2 denier, 3 denier, 5 denier, 10 denier, 20 denier, 50 denier, and 100 denier. The outer liquid guiding tube 9321 is preferably formed by bonding two-component fibers, more preferably by heat bonding two-component fibers with a core-sheath structure, thereby avoiding the use of adhesives during manufacturing. The core-sheath structure includes a core layer and a skin layer covering the outer wall surface of the core layer. This tubular porous material integrally formed by fiber bonding provides good strength for the outer liquid guiding tube 9321, facilitating the assembly and fixation of the inner liquid guiding cotton 9322 and the resistive mesh 931 during the manufacturing process of the atomizing core 930.

[0048] During the assembly of the atomizing core 930, the outer liquid guiding tube 9321 will not unravel or break easily. The porosity of the wall of the outer liquid guiding tube 9321 is preferably 70% to 95%, such as 70%, 75%, 80%, 85%, 88%, 90%, or 95%. An outer liquid guiding tube 9321 with a wall porosity of 70% to 95% exhibits good strength, along with good liquid guiding speed and high liquid content. More preferably, the porosity of the wall of the outer liquid guiding tube 9321 is 75% to 90%.

[0049] like Figure 1 and Figure 2 As shown, the inner layer of liquid-conducting cotton 9322 is rolled into a cylindrical shape, and an inner layer liquid-conducting cotton seam 9323 is formed between the two ends of the inner layer of liquid-conducting cotton 9322 in the circumferential direction. The inner layer of liquid-conducting cotton 9322 is fixed by the outer layer of liquid-conducting tube 9321, thereby preventing it from unraveling. The resistor mesh 931 is also rolled into a cylindrical shape, and the two ends of the resistor mesh 931 in the circumferential direction are located on both sides of the inner layer of liquid-conducting cotton seam 9323 formed by the inner layer of liquid-conducting cotton 9322, thereby preventing the two ends of the resistor mesh 931 from contacting and causing a short circuit.

[0050] like Figure 1 and Figure 2 As shown, when the inner liquid-conducting cotton 9322 and the resistive mesh 931, rolled into a cylindrical shape, are inserted into the outer liquid-conducting tube 9321, the outer peripheral wall of the inner liquid-conducting cotton 9322 adheres to the inner peripheral wall of the outer liquid-conducting tube 9321, and the resistive mesh 931 adheres to the inner peripheral wall of the inner liquid-conducting cotton 9322. The inner liquid-conducting cotton 9322 and the resistive mesh 931, rolled into a cylindrical shape, are fixed by the outer liquid-conducting tube 9321, thereby maintaining the stability of their shape and function.

[0051] The atomizing core 930 of the present invention may further include an atomizing core center rod (not shown), which passes through the atomizing core through-hole 9328 of the atomizing core 930 and is wrapped by a resistive mesh 931 and an inner liquid-guiding cotton 9322. The atomizing core center rod helps to roll the inner liquid-guiding cotton 9322 and the resistive mesh 931 into a cylindrical shape and shape them, so that the atomizing core 930 as a whole has better strength and is not easily damaged when assembling the aerosol cartridge. The atomizing core center rod is usually removed after the aerosol cartridge is assembled.

[0052] like Figure 1 and 2 As shown, the height of the resistive mesh 931 of the present invention is less than the height of the inner liquid-guiding cotton 9322, so as to avoid the resistive mesh 931 from contacting the outer liquid-guiding tube 9321, and also to avoid the resistive mesh 931 from protruding from both ends of the atomizing core 930 and being damaged.

[0053] The inner liquid-guiding cotton 9322 is composed of multiple layers of non-woven fabric, typically 2 to 9 layers, preferably 3 to 7 layers. The non-woven fabric can be horizontal, vertical, twill, or perforated. The non-woven fabric material closest to the resistive mesh 931 is usually cellulose fiber or carbon fiber, preferably cotton fiber or hemp fiber. These materials are not only readily available, but also contribute to producing a good taste during atomization.

[0054] The atomizing core 930 of the present invention also includes a wire 933, and the two ends of the resistor mesh 931 are connected to the wire 933 by welding or other means.

[0055] In the aerosol cartridge using the atomizing core 930 of this invention, the liquid in the aerosol cartridge permeates through the outer liquid guiding tube 9321 and is then transferred to the inner liquid guiding cotton 9322, where it is heated and atomized by the resistive mesh 931 during operation. Because of the sufficient contact between the outer liquid guiding tube 9321 and the inner liquid guiding cotton 9322, the liquid guiding efficiency is significantly improved, which helps to enhance the aerosol's flavor and extend the lifespan of the atomizing core 930.

[0056] Second Embodiment

[0057] Figure 3 This is a schematic diagram showing the longitudinal section of an atomizing core according to a second embodiment of the present invention. This embodiment is similar to the first embodiment, and the similarities with the first embodiment will not be repeated.

[0058] like Figure 3As shown, the atomizing core 930 of the present invention may further include an atomizing core housing 9324, with the outer peripheral walls of both ends of the outer liquid guiding tube 9321 attached to the inner peripheral wall of the atomizing core housing 9324. This prevents leakage between the outer liquid guiding tube 9321 and the atomizing core housing 9324 during use of the aerosol cartridge. A liquid guiding hole 9325 may be provided on the atomizing core housing 9324. The liquid guiding hole 9325 may be configured as a hole, groove, or annular shape, allowing liquid in the aerosol cartridge to permeate through the liquid guiding hole 9325 into the outer liquid guiding tube 9321 and the inner liquid guiding cotton 9322. The rigid atomizing core housing 9324 protects the internal structure of the atomizing core 930 and facilitates the installation of the aerosol cartridge.

[0059] Third Embodiment

[0060] Figure 4 This is a schematic diagram of the structure of an aerosol bullet according to a third embodiment of the present invention; Figure 5 This is a schematic diagram of the structure of a liquid recovery element according to a third embodiment of the present invention; Figure 6 According to Figure 5 The diagram shows a cross-sectional view of the liquid recovery element at BB.

[0061] like Figures 4 to 6 As shown, the aerosol bullet 800 according to the third embodiment of the present invention includes any of the aforementioned atomizing core 930.

[0062] According to the third embodiment of the present invention, the aerosol bullet 800 further includes a liquid storage element 100 for supplying liquid to the atomizing core 930, a buffer body 843 disposed below the liquid storage element 100, and a liquid recovery element 600. One end of the liquid recovery element 600 is connected to the liquid storage element 100, and the other end is connected to the buffer body 843. The end of the liquid recovery element 600 connected to the buffer body 843 partially compresses the buffer body 843. The liquid recovery element 600 includes a sleeve 6501 and a core 640 inserted into the sleeve 6501. There is no axial through hole between the sleeve 6501 and the core 640 or inside the core 640.

[0063] In this embodiment, the core 640 is preferably a porous capillary material, such as porous plastic, porous metal, porous bonding fiber, etc., and more preferably a porous capillary material made of two-component fibers bonded together with a core-sheath structure.

[0064] In this embodiment, the aerosol bullet 800 further includes an aerosol bullet shell 810 and a second shell base 824 disposed at the bottom of the aerosol bullet shell 810, a first shell base 823 disposed inside the aerosol bullet shell 810 and spaced apart from the second shell base 824, and a buffer chamber 828 disposed between the first shell base 823 and the second shell base 824, with a buffer body 843 located in the buffer chamber 828.

[0065] Specifically, in this embodiment, as Figure 4 As shown, preferably, the aerosol cartridge shell 810 forms a cavity with an opening at the bottom. The top of the aerosol cartridge shell 810 extends into the cavity to form a liquid storage element through hole 130. The first shell base 823 is inserted into the cavity from the bottom of the aerosol cartridge shell 810, forming a liquid storage element 100 together with the aerosol cartridge shell 810. An installation gap for mounting the atomizing core 930 is formed between the first shell base 823 and the wall of the liquid storage element through hole 130. The liquid storage element through hole 130 also serves as an aerosol channel 1303. The upper part of the atomizing core 930 is connected and sealed to the connection port 1302 at the lower part of the aerosol channel 1303, and the lower part of the atomizing core 930 is connected and sealed to the atomizing core assembly port 826 in the middle of the first shell base 823. The sleeve 6501 of the liquid recovery element 600 can be integrally formed with the first shell base 823. The second housing base 824 is spaced apart from the first housing base 823 to seal the bottom opening of the aerosol shell 810 and to form a buffer chamber 828 between the first housing base 823 and the second housing base 824. The buffer body 843 is located in the buffer chamber 828 and can prevent liquid from flowing freely in the buffer chamber 828, thereby preventing liquid from leaking to the outside of the aerosol shell.

[0066] In this embodiment, the aerosol bullet 800 also includes an isolation tube 829, which connects to the base through hole 1122 of the aerosol bullet 800 and extends toward the atomizing core 930, which can effectively prevent the liquid in the buffer chamber 828 from leaking from the base through hole 1122 to the outside of the aerosol bullet 800.

[0067] In this embodiment, the liquid recovery element 600 is disposed on the first housing base 823. One end of the liquid recovery element 600 is connected to the liquid storage element 100, and the other end is connected to the buffer body 843 disposed in the buffer chamber 828.

[0068] In the aerosol canister 800, the liquid recovery element 600 can be configured as one or more.

[0069] When the aerosol bullet 800 is in operation, the liquid in the liquid storage element 100 contacts and permeates the outer liquid guide tube 9321, and then further permeates the inner liquid guide cotton 9322, and is atomized when the atomizing core 930 is heated. In this embodiment, external air can enter the liquid storage element 100 through the outer liquid guide tube 9321, thereby maintaining the pressure stability in the liquid storage element.

[0070] In this embodiment, when the external temperature or pressure changes, such as during air transport or when the air temperature rises, the liquid leaking from the liquid storage element 100 can be absorbed and temporarily stored by the buffer body 843. When the external temperature or pressure returns to normal, or when the liquid in the liquid storage element 100 is atomized and consumed, most of the liquid temporarily stored in the buffer body 843 can be returned to the liquid storage element 100 through the liquid recovery element 600.

[0071] Because the liquid recovery element 600 partially compresses the buffer body 843 at one end connected to the buffer body 843, the density near the contact area between the buffer body 843 and the liquid recovery element 600 increases. This facilitates the accumulation of liquid temporarily stored in the buffer body 843 near the contact area, allowing the liquid in the buffer body 843 to be effectively recovered to the liquid storage element 100. The buffer body 843 is preferably made of bonded fibers, non-woven fabric, or sponge.

[0072] Fourth embodiment

[0073] Figure 7 This is a schematic diagram of the structure of an aerosol bullet according to a fourth embodiment of the present invention; Figure 8 This is a schematic diagram of the structure of a liquid recovery element according to a fourth embodiment of the present invention; Figure 9 According to Figure 8 The diagram shows a cross-sectional view of the liquid recovery element at point CC. Figure 10 This is a schematic diagram of another liquid recovery element according to a fourth embodiment of the present invention. This embodiment is similar to the third embodiment, and the similarities with the third embodiment will not be repeated.

[0074] like Figures 7 to 10 As shown, the aerosol bullet 800 according to the fourth embodiment of the present invention includes any of the aforementioned atomizing core 930.

[0075] According to the fourth embodiment of the present invention, the aerosol bullet 800 further includes a liquid storage element 100 for supplying liquid to the atomizing core 930, a buffer body 843 disposed below the liquid storage element 100, and a liquid recovery element 600. One end of the liquid recovery element 600 is connected to the liquid storage element 100, and the other end is connected to the buffer body 843. The end of the liquid recovery element 600 connected to the buffer body 843 partially compresses the buffer body 843. The liquid recovery element 600 includes a sleeve 6501 and a core 640 inserted into the sleeve 6501. At least one first through hole 6301 axially penetrating the core 640 is included between the sleeve 6501 and the core 640 and within the core 640. The first through hole 6301 is blocked by the buffer body 843. The liquid recovery element 600 communicates with the external atmosphere through the buffer body 843.

[0076] In this embodiment, the first through hole 6301 is disposed within the core 640, or the first through hole 6301 is disposed between the core 640 and the sleeve 6501. Preferably, the first through hole 6301 is disposed within the core 640, that is, the first through hole 6301 axially penetrating the air guide assembly refers to the first through hole 6301 axially penetrating the core 640.

[0077] In this embodiment, the core 640 can be plastic or metal, but is preferably a porous capillary material, such as porous plastic, porous metal, porous bonding fiber, etc., and more preferably a porous capillary material made of two-component fibers with a core-sheath structure bonded together.

[0078] like Figure 8 As shown, the central axis of the first through hole 6301 coincides with the central axis of the core 640; as Figure 10 As shown, the central axis of the first through hole 6301 is parallel to the central axis of the core 640, but they do not coincide.

[0079] In this embodiment, the maximum inscribed circle diameter of the minimum cross-section of the first through hole 6301 is preferably set to 0.2mm to 2.0mm, such as 0.2mm, 0.3mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, and 2.0mm. Thus, the first through hole 6301 can also be formed as a capillary, which can generate capillary force and play a liquid sealing role. This allows a high negative pressure to be generated inside the liquid storage element 100 of the aerosol bullet 800, which can effectively prevent liquid leakage in the liquid storage element 100.

[0080] In this embodiment, the liquid recovery element 600 is connected to the external atmosphere via the buffer body 843. When the liquid in the storage element 100 is consumed by atomization, the external atmosphere can replenish air to the storage element 100 through the liquid recovery element 600, or through the outer liquid guide tube 9321 of the atomizing core 930, thereby maintaining the pressure stability in the storage element 100. When the external temperature or pressure changes, such as during air transport or when the temperature rises, the liquid leaking from the storage element 100 can be absorbed by the buffer body 843 and temporarily stored. When the external temperature or pressure returns to normal, or when the liquid in the storage element 100 is consumed by atomization, most of the liquid temporarily stored in the buffer body 843 can be returned to the storage element 100 through the liquid recovery element 600.

[0081] In this embodiment, the liquid recovery element 600 partially compresses the buffer body 843 at one end of the connection between the buffer body 843 and the liquid recovery element 600. This increases the density near the contact area between the buffer body 843 and the liquid recovery element 600, which facilitates the formation of a liquid seal at the air inlet port connecting the liquid recovery element 600 and the buffer body 843, improving the reliability of the liquid seal in the first through hole 6301 and thus increasing the reliability of the air control by the liquid recovery element 600. It also facilitates the accumulation of liquid temporarily stored in the buffer body 843 near the contact area between the buffer body 843 and the liquid recovery element 600, allowing the liquid in the buffer body 843 to be effectively recovered to the liquid storage element 100. The buffer body 843 is preferably made of bonded fibers, non-woven fabric, or sponge.

[0082] like Figures 7 to 10 As shown, the liquid recovery element 600 further includes a buffer tube 6502, which includes at least one second through hole 6302 axially penetrating the buffer tube 6502. The buffer tube 6502 is connected to the sleeve 6501, and the second through hole 6302 is connected to the core 640. One end of the liquid recovery element 600 having the second through hole 6302 is connected to the liquid storage element 100.

[0083] In this embodiment, the maximum inscribed circle diameter of the minimum cross-section of the second through hole 6302 is 0.2 mm to 2.5 mm. For example... Figures 7 to 10 As shown, the maximum inscribed circle diameter of the minimum cross-section of the second through-hole 6302 is from 0.2 mm to 2.5 mm, for example, 0.2 mm, 0.3 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, 2.0 mm, and 2.5 mm. When the maximum inscribed circle diameter of the minimum cross-section of the second through-hole 6302 is from 0.2 mm to 2.5 mm, the second through-hole 6302 can generate a larger capillary force, making the liquid storage effect of the second through-hole 6302 better.

[0084] like Figure 8 and Figure 9 As shown, an axial partition plate 6504 can be provided in the second through hole 6302 to divide the second through hole 6302 into multiple parts, which can reduce the maximum inscribed circle diameter of the minimum cross-section of the second through hole 6302 and improve the liquid storage effect. Preferably, more than one axial partition plate 6504 is provided in the second through hole 6302. For example, an axial partition plate 6504 is provided at the lower part of the second through hole 6302, and a second axial partition plate 6504 is provided at the upper part of the second through hole 6302, and the two axial partition plates 6504 are arranged in a cross shape.

[0085] To ensure better communication between the liquid in the storage element 100 and the core 640 or the buffer tube 6502, such as Figures 7 to 10 As shown, a first side hole 6503 can be provided on the peripheral wall of the buffer tube 6502; or as shown... Figure 10 As shown, the outlet of the first through hole 6301 on the upper end face of the sleeve 6501 and the core 640 is at least partially located outside the projection of the buffer tube 6502 on the upper end face of the sleeve 6501 and the core 640. Furthermore, a second side hole (not shown) can be provided on the peripheral wall of the upper part of the sleeve 6501, and the second side hole can communicate with the core 640.

[0086] In this embodiment, the liquid storage element 100 is connected to the buffer body 843 through the liquid recovery element 600, and is connected to the external atmosphere through the vent 827 of the isolation tube 829, the isolation tube 829, and the base through hole 1122. The external atmosphere enters the liquid storage element 100 through the base through hole 1122, the isolation tube 829, the vent 827, the buffer body 843, and the liquid recovery element 600, thereby realizing the connection between the liquid storage element 100 and the external atmosphere through the liquid recovery element 600.

[0087] In another embodiment (not shown), one end of the isolation tube 829 is connected to the base 824 of the second atomizing core housing 9324, and the other end of the isolation tube 829 abuts against the lower end of the atomizing core 930. Thus, the isolation tube 829 can further effectively prevent the liquid in the buffer chamber 828 from leaking out of the aerosol bullet 800 through the base through hole 1122.

[0088] In the aerosol bullet 800 of this embodiment, preferably, the bottom of the first side hole 6503 is flush with the bottom of the liquid storage element 100, so that the liquid in the aerosol bullet 800 can always enter the liquid recovery element 600 through the first side hole 6503 before the liquid is exhausted.

[0089] In the aerosol canister 800, one or more liquid recovery elements 600 can be provided, and the liquid recovery elements 600 in the third and fourth embodiments can be used in combination. Especially in large-capacity aerosol canisters, providing multiple liquid recovery elements 600 can improve the liquid recovery efficiency in the buffer body 843, making the leak-proof performance more reliable.

[0090] The atomizing core 930 according to the present invention has a long lifespan and can be used in a large-capacity aerosol cartridge 800. If the aerosol generated by the atomizing core 930 passes through a long aerosol channel 1303, the taste will be affected due to a significant temperature drop. In this case, an aerosol channel 1303 with a partition can be provided in the aerosol cartridge 800 to reduce heat loss when the aerosol passes through the aerosol channel, thereby reducing the impact on the taste. Preferably, the atomizing core housing 9324 extends into the aerosol channel 1303, thereby forming a partition between the atomizing core housing 9324 and the peripheral wall of the aerosol channel 1303.

[0091] In this embodiment, when the aerosol bullet 800 is in operation, the liquid in the liquid storage element 100 contacts and permeates the outer liquid guide tube 9321, and then further permeates the inner liquid guide cotton 9322. It is then atomized when the atomizing core 930 is heated. Outside air can be replenished into the liquid storage element 100 through the liquid recovery element 600 or the outer liquid guide tube 9321 of the atomizing core. After the liquid recovery element 600 absorbs sufficient liquid, the first through hole 6301 is liquid-sealed. The buffer body 843 absorbs some liquid from the liquid recovery element 600 and further liquid-seales the air inlet port connecting the liquid recovery element 600 and the buffer body 843, increasing the reliability of the air guidance controlled by the liquid recovery element 600.

[0092] In this invention, the liquid storage element 100 is a component for storing the atomized liquid. Different liquids can be stored therein depending on the application, such as nicotine solution, CBD solution, fragrance, pharmaceutical solution, etc.

[0093] According to the aerosol bullet 800 of this embodiment, when the buffer tube 6502 is provided, even if the aerosol bullet 800 is placed upside down or on its side, and the liquid recovery element 600 is just separated from the liquid in the liquid storage element 100, and the liquid guiding element 932 of part of the atomizing core 930 is still in contact with the liquid, since the second through hole 6302 is connected to the core body 640, the liquid stored in the second through hole 6302 can be conducted to the core body 640, thereby maintaining the liquid seal in the first through hole 6301 and preventing the liquid from leaking from the atomizing core 930 due to the disappearance of the negative pressure in the aerosol bullet 800.

[0094] Fifth Embodiment

[0095] Figure 11 This is a schematic diagram of an aerosol cannon according to a fifth embodiment of the present invention. This embodiment is similar to the third embodiment, and the similarities with the third embodiment will not be repeated. Figure 11 As shown, the aerosol bullet 800 according to the fifth embodiment of the present invention includes any of the aforementioned atomizing core 930.

[0096] In this embodiment, the aerosol bullet 800 includes an aerosol bullet shell 810, which forms a cavity with an opening at the bottom. The top of the aerosol bullet shell 810 extends into the cavity to form a liquid storage element through hole 130, which also serves as an aerosol channel 1303. The inner peripheral wall of the outer liquid guide tube 9321 of the atomizing core 930 is attached to the outer peripheral wall of the connection port 1302 at the bottom of the aerosol channel 1303.

[0097] In this embodiment, the aerosol bullet 800 may further include an inner airway tube 1307 that is attached to the inner peripheral wall of the aerosol channel 1303.

[0098] In this embodiment, the aerosol bullet 800 further includes a second housing base 824 disposed at the bottom of the aerosol bullet housing 810, a first housing base 823 disposed inside the aerosol bullet housing 810 and spaced apart from the second housing base 824, a buffer chamber 828 disposed between the first housing base 823 and the second housing base 824, and a liquid storage element 100 disposed between the aerosol bullet housing 810 and the first housing base 823. The middle part of the first housing base 823 protrudes into the aerosol channel 1303 to form an atomizing core assembly port 826, and the inner peripheral wall of the outer liquid guide tube 9321 of the atomizing core 930 covers the outer peripheral wall of the atomizing core assembly port 826.

[0099] Specifically, in this embodiment, as Figure 11 As shown, preferably, the aerosol cartridge housing 810 forms a cavity with an opening at the bottom. The top of the aerosol cartridge housing 810 extends into the cavity to form a liquid storage element through hole 130. The first housing base 823 is inserted into the cavity from the bottom of the aerosol cartridge housing 810, forming a liquid storage element 100 together with the aerosol cartridge housing 810. An installation gap for mounting the atomizing core 930 is formed between the first housing base 823 and the wall of the liquid storage element through hole 130. The liquid storage element through hole 130 also serves as an aerosol channel 1303. The upper part of the atomizing core 930 is connected to the connection port 1302 at the lower part of the aerosol channel 1303. Preferably, the inner peripheral wall of the upper part of the outer liquid guide tube 9321 is attached to the outer peripheral wall of the connection port 1302. The lower part of the atomizing core 930 is connected to the atomizing core assembly port 826 in the middle of the first housing base 823. Preferably, the inner peripheral wall of the lower part of the outer liquid guide tube 9321 is attached to the outer peripheral wall of the atomizing core assembly port 826.

[0100] This connection method allows for a more stable liquid content in the outer liquid guide tube 9321, thereby improving the stability of the aerosol. The second housing base 824 is spaced apart from the first housing base 823 to seal the bottom opening of the aerosol shell 810 and to form a buffer chamber 828 between the first housing base 823 and the second housing base 824.

[0101] A liquid-absorbing material (not shown) can be placed in the buffer chamber 828 to prevent small amounts of liquid from leaking to the outside of the aerosol canister. The aerosol canister 800 of this embodiment is suitable for aerosol canisters with smaller capacity, and is especially suitable for applications with smaller aerosol particles.

[0102] When the aerosol bullet 800 is working, the liquid in the liquid storage element 100 comes into contact with and permeates the outer liquid guide tube 9321, and then further permeates the inner liquid guide cotton 9322, and is atomized when the atomizing core 930 is heated.

[0103] In this embodiment, external air can enter the liquid storage element 100 through the outer liquid guide tube 9321 or the connection between the outer liquid guide tube 9321 and the aerosol channel or the connection between the outer liquid guide tube 9321 and the atomizing core assembly port 826, thereby maintaining the pressure stability in the liquid storage element.

[0104] In this embodiment, an axial notch, groove, or rib (not shown) can be provided on the outer peripheral wall of the connection port 1302 at the lower part of the atomizing channel 1303 or the atomizing core assembly port 826 in the middle of the first housing base 823 to form a capillary channel between the connection port 1302 at the lower part of the atomizing channel 1303 or the atomizing core assembly port 826 in the middle of the first housing base 823, so as to increase the air supply from the outside to the liquid storage element 100.

[0105] like Figure 11 As shown, the aerosol projectile may further include an inner airway tube 1307 attached to the inner peripheral wall of the aerosol channel. The inner airway tube 1307 is preferably made of a porous material, such as a porous silicone tube or a porous fiber tube. The porous material of the inner airway tube 1307 reduces heat exchange between the aerosol in the aerosol channel 1303 and the liquid or gas in the liquid storage element 100, reduces cooling of the aerosol by the inner peripheral wall of the aerosol channel 1303, and effectively reduces condensation. Simultaneously, it also reduces heating of the air in the liquid storage element 100 during atomization and the resulting atomization instability.

[0106] More preferably, the airway inner tube 1307 is a porous fiber tube made of two-component fiber bonded together, which also has the function of absorbing condensate in the aerosol channel 1303.

[0107] Preferably, the lower end of the airway inner tube 1307 is abutted against the inner liquid-guiding cotton 9322 of the atomizing core 930, so that the liquid absorbed in the airway inner tube 1307 is returned to the inner liquid-guiding cotton 9322, thereby improving the utilization rate of the liquid. Since the airway inner tube 1307 has both the functions of absorbing and releasing liquid, the leakage prevention function of the aerosol bullet 800 can be increased.

[0108] In this invention, the outer liquid guiding tube 9321 comprises a tubular porous material integrally formed by fiber bonding, wherein the fibers can be filaments or staple fibers. The fiber fineness range is preferably from 1.5 denier to 100 denier, such as 1.5 denier, 2 denier, 3 denier, 5 denier, 10 denier, 20 denier, 50 denier, and 100 denier. The outer liquid guiding tube 9321 is preferably formed by bonding two-component fibers, more preferably by heat bonding two-component fibers with a core-sheath structure, thereby avoiding the use of adhesives during manufacturing. The core-sheath structure includes a core layer and a sheath covering the outer wall of the core layer; common sheath materials include polyethylene, polypropylene, copolyester, and nylon 6. This tubular porous material integrally formed by fiber bonding has good strength, facilitating the assembly and fixation of the inner liquid guiding cotton 9322 and the resistive mesh 931, which cannot form a stable shape on their own, during the manufacturing process of the atomizing core 930.

[0109] During the assembly of the atomizing core 930, the outer liquid guiding tube 9321 will not scatter or break easily. The porosity of the outer liquid guiding tube 9321 wall is 20% to 95%, such as 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, and 95%. The outer liquid guiding tube 9321 with a wall porosity of 20% to 95% has good strength and good liquid guiding speed. An outer liquid guiding tube with a wall porosity of 20% to 70% has a lower liquid content, which is beneficial for the atomizing core to produce smaller aerosol particles; an outer liquid guiding tube with a wall porosity of 70% to 95% has a higher liquid content, which is beneficial for the atomizing core to produce larger aerosol particles.

[0110] Figure 12 This is a schematic diagram of the structure of an atomizing module according to a fifth embodiment of the present invention. Figure 12 As shown, the atomizing module according to the fifth embodiment of the present invention includes any of the aforementioned atomizing cores 930.

[0111] The atomizing module also includes a second housing base 824 located at the bottom of the atomizing module, and a first housing base 823 located above the second housing base 824 and spaced apart from the second housing base 824. The middle of the first housing base 823 protrudes upward to form an atomizing core assembly port 826. The inner peripheral wall of the outer liquid guide tube 9321 of the atomizing core 930 is attached to the outer peripheral wall of the atomizing core assembly port 826.

[0112] The atomizing module also includes a wire mounting hole 8234 located at the bottom of the first housing base 823, an electrode 936 mounted on the second housing base 824, a wire 933 of the atomizing core 930 passing through the atomizing core assembly port 826 and inserted into the wire mounting hole 8234, and the upper part of the electrode 936 inserted into the wire mounting hole 8234 and connected to the wire 933.

[0113] Sixth Embodiment

[0114] Figure 13 This is a schematic diagram of an aerosol bullet according to a sixth embodiment of the present invention. This embodiment is similar to the fifth embodiment, and the similarities with the fifth embodiment will not be repeated.

[0115] like Figure 13 As shown, the difference between this embodiment and the fifth embodiment is that the aerosol bullet 800 also includes a porous liquid storage 105 located at the bottom of the liquid storage element 100 and covering the outer periphery of the atomizing core 930.

[0116] When the aerosol canister 800 is inverted or placed horizontally and the liquid in the aerosol canister 800 is low, the liquid in the porous liquid storage 105 can ensure that there is enough liquid in the outer liquid guide tube 9321, thereby preventing the liquid storage element 100 from losing pressure or the liquid in the aerosol canister 800 from leaking.

[0117] The porous liquid reservoir 105 can be made of fibers, preferably bonded from two-component fibers. Preferably, the porosity of the porous liquid reservoir 105 is not less than the porosity of the outer liquid guide tube 9321, so that the liquid in the porous liquid reservoir 105 can be fully utilized in the later stages of use of the aerosol cartridge 800. Preferably, the height of the porous liquid reservoir 105 does not exceed the height of the atomizing core 930.

[0118] In summary, according to the atomizing core 930 of the present invention, the inner liquid-guiding cotton 9322 is directly fixed inside the outer liquid-guiding tube 9321 integrally formed by fiber bonding, eliminating the inner steel tube. This allows for full contact between the inner and outer liquid-guiding materials and significantly increases the direct contact area between them. Therefore, the efficiency of liquid transfer from the outer liquid-guiding material to the inner liquid-guiding material in the atomizing core 930 can be greatly improved, ensuring sufficient liquid supply to the inner liquid-guiding cotton 9322. Even in applications with high atomization volume, insufficient liquid supply to the inner liquid-guiding cotton 9322 will not occur, which is beneficial for improving the aerosol taste and significantly extending the life of the atomizing core 930.

[0119] The outer liquid-guiding tube 9321, integrally formed from a tubular porous material bonded with fibers, possesses excellent strength, facilitating the assembly and fixation of the inner liquid-guiding cotton 9322 and the resistive mesh 931 during the manufacturing process of the atomizing core 930. The outer liquid-guiding tube will not scatter or break during the assembly of the atomizing core 930. Compared to existing technologies, the atomizing core 930 of this invention improves the aerosol flavor, significantly extends the lifespan of the atomizing core 930, substantially reduces costs, and is suitable for automated assembly.

[0120] When the external environment changes during storage, transportation and use, the aerosol bullet 800 according to the present invention can effectively prevent liquid leakage regardless of its placement, including when the liquid recovery element 600 in the aerosol bullet 800 leaves the liquid surface but the atomizing core 930 is still in contact with the liquid surface.

[0121] Furthermore, the above embodiments of the present invention are merely illustrative of the principles and effects of the invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
