Description

Technical Field

[0001] The present invention relates to an independent air guiding element, an aerosol cartridge applying the independent air guiding element, and particularly to an independent air guiding element and an aerosol cartridge used in application fields such as electronic cigarettes and atomization of pharmaceutical solutions. Background Art

[0002] Atomization technology is widely used in fields such as electronic cigarettes and pharmaceutical atomization. A common technology in electronic cigarettes is to heat a liquid guiding element of an atomization core directly connected to e-liquid to atomize the liquid.

[0003] In a conventional aerosol cartridge, the atomization liquid is stored in a liquid storage element made of a porous material. The liquid in the porous material is transmitted to the liquid guiding element of the atomization core through a liquid guiding through hole on the outer shell of the atomization core for atomization. Since the atomization liquid is held by the capillary force of the porous material, the aerosol cartridge is not prone to liquid leakage. However, as the liquid in the porous material is released, the liquid releasing ability of the porous material continuously decays, resulting in a decline in atomization amount and taste, and affecting the consumption experience.

[0004] In another existing aerosol cartridge, an independent air guiding element is adopted, and the liquid is stored in a liquid storage element formed by an aerosol cartridge housing. This technology can control the uniform release of the liquid during atomization and effectively prevent liquid leakage of the aerosol cartridge under normal circumstances. However, in some special cases, for example, when the aerosol cartridge is sucked to a high temperature and immediately placed upside down or sideways, and exactly the independent air guiding element is separated from the liquid in the liquid storage element and part of the liquid guiding element of the atomization core still contacts the liquid, the negative pressure generated during the cooling process of the aerosol cartridge will suck the liquid in the through hole of the independent air guiding element empty. After the through hole of the independent air guiding element loses liquid sealing, the negative pressure in the liquid storage element disappears, resulting in liquid leakage from the liquid guiding element of the atomization core due to the action of gravity. Summary of the Invention

[0005] To solve the problems existing in the prior art, the present invention provides an independent air guiding element, which includes an air guiding assembly and a buffer tube. The air guiding assembly includes a sleeve, a core body inserted into the sleeve, and at least one first through hole axially penetrating the air guiding assembly. The buffer tube includes at least one second through hole axially penetrating the buffer tube. The buffer tube communicates with the sleeve, and the second through hole communicates with the core body.

[0006] Furthermore, the maximum inscribed circle diameter of the minimum cross-section of the second through hole is 0.2 mm to 2.5 mm.

[0007] Furthermore, the height of the buffer tube is greater than or equal to 1.5 times the maximum inscribed circle diameter of the minimum cross-section of the second through hole.

[0008] Furthermore, a first side hole is provided on the peripheral wall of the buffer tube.

[0009] Furthermore, a partition plate is axially arranged on the inner peripheral wall of the buffer tube.

[0010] Furthermore, the first side hole is a slit extending from the bottom to the top of the buffer tube.

[0011] Furthermore, the first through hole is arranged in the core body, or the first through hole is arranged between the core body and the sleeve.

[0012] Furthermore, the core body is a porous capillary material.

[0013] Furthermore, second side holes are arranged on the peripheral wall of the sleeve, and the second side holes communicate with the core body.

[0014] Furthermore, the second side holes are slits formed by extending downward from the top of the sleeve.

[0015] Furthermore, the central axis of the first through hole is parallel to the central axis of the core body but does not coincide with it.

[0016] Furthermore, the outlet of the first through hole on the upper end face of the air guiding assembly is at least partially located outside the projection of the buffer tube on the upper end face of the air guiding assembly.

[0017] Furthermore, the first through hole is a groove provided on the side wall of the core body, and the lower end face of the sleeve is flush with the lower end face of the first through hole.

[0018] The present invention also provides an aerosol bomb, and the aerosol bomb includes the independent air guiding element of any one of the above.

[0019] Furthermore, the aerosol bomb further includes an atomization core, a liquid storage element for supplying liquid to the atomization core, and a buffer body. One end of the independent air guiding element having the second through hole communicates with the liquid storage element, the other end of the independent air guiding element communicates with the buffer body, and the independent air guiding element communicates with the external atmosphere through the buffer body.

[0020] Furthermore, one end of the independent air guiding element communicating with the buffer body locally compresses the buffer body.

[0021] Furthermore, the aerosol bomb further includes an aerosol bomb housing, a second housing base provided at the bottommost part of the aerosol bomb housing, a first housing base provided inside the aerosol bomb housing and spaced from the second housing base, and a buffer chamber provided between the first housing base and the second housing base. The buffer body is located in the buffer chamber.

[0022] Further, the atomization core includes an atomization core housing, an outer housing liquid guiding through hole provided on the atomization core housing, and an atomization core liquid guiding element for blocking the outer housing liquid guiding through hole. The height from the top of the independent air guiding element to the bottom of the liquid storage element is not less than the height from the top of the outer housing liquid guiding through hole to the bottom of the liquid storage element.

[0023] After the independent air guiding element according to the present invention is wetted with liquid, when the aerosol cartridge is placed upside down or sideways and the independent air guiding element is separated from the liquid, since the core body can contact the liquid in the buffer tube, a liquid seal is maintained in the first through hole.

These embodiments are provided to disclose the present invention in detail and completely, and to fully convey the scope of the present invention to those skilled in the art.

[0048] First Embodiment

[0049] Figure 1 FIG. is a schematic cross-sectional structure diagram of an independent air guiding element according to the first embodiment of the present invention; Figure 2 According to Figure 1 FIG. is a schematic cross-sectional structure diagram of the independent air guiding element at A-A; Figure 3 According to Figure 1 FIG. is a schematic cross-sectional structure diagram of the independent air guiding element at B-B.

[0050] As Figures 1 to 3 shown, the independent air guiding element 600 according to the first embodiment of the present invention includes an air guiding assembly and a buffer tube 6502. The air guiding assembly includes a sleeve 6501, a core 640 inserted into the sleeve 6501, and at least one first through hole 6301 axially penetrating the air guiding assembly. The buffer tube 6502 includes at least one second through hole 6302 axially penetrating the buffer tube 6502. The sleeve 6501 communicates with the buffer tube 6502, and the second through hole 6302 communicates with the core 640.

[0051] The independent air guiding element 600 according to the present invention is applicable to the aerosol bomb 800 described later. When the independent air guiding element 600 is wetted with liquid, the liquid will be stored in the second through hole 6302 in the buffer tube 6502. When the aerosol bomb 800 is placed upside down or sideways and the independent air guiding element 600 is separated from the liquid, the liquid stored in the second through hole 6302 can supplement the liquid into the core 640, so that the core 640 can always be in contact with the liquid. Thus, the liquid sealing function can be maintained in the first through hole 6301.

[0052] In the present invention, the maximum inscribed circle diameter of the minimum cross-section is defined as the diameter of the largest circle among the circles that are tangent to the corresponding sides or curves of the minimum cross-section of the through-hole. When the cross-section of the through-hole is circular, the maximum inscribed circle is the circular shape itself. When the cross-section of the through-hole is a non-circular or irregular geometric planar figure, the maximum inscribed circle is the largest circle among the circles that are tangent to the corresponding sides or curves of the through-hole. When there is a partition in the through-hole, the partition should also be regarded as part of the side or curve.

[0053] In this embodiment, 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. As Figure 2 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, such as 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, 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 relatively large capillary force, making the effect of storing liquid in the second through-hole 6302 better.

[0054] In this embodiment, preferably, the height of the buffer tube 6502 is greater than or equal to 1.5 times the maximum inscribed circle diameter of the minimum cross-section of the second through-hole 6302. With such a setting, when the aerosol cartridge 800 is placed upside down or on its side, the liquid stored in the second through-hole 6302 can enable the first through-hole 6301 to perform a better liquid sealing function.

[0055] In this embodiment, preferably, a first side hole 6503 is provided on the peripheral wall of the buffer tube 6502. When the independent air guiding element 600 of the present invention is installed in the aerosol cartridge 800, the bottom of the first side hole 6503 is flush with the bottom of the liquid storage element 100 of the aerosol cartridge 800. Thus, before the liquid in the liquid storage element 100 is exhausted, the liquid in the liquid storage element 100 can always enter the independent air guiding element 600 through the first side hole 6503, so as to generate a liquid seal in the first through-hole 6301. At the same time, when the liquid storage element 100 needs air, the outside air can supplement air to the liquid storage element 100 through the first through-hole 6301.

[0056] In this embodiment, partition plates 6504 can be axially provided on the inner peripheral wall of the buffer tube 6502, for example, 1, 2, 3, 4, or 5 partition plates 6504. As Figure 2As shown, the partition plate 6504 is preferably arranged to extend from the inner peripheral wall of the buffer tube 6502 towards the center of the second through hole 6302. The arrangement of the partition plate 6504 can further reduce the maximum inscribed circle diameter of the minimum cross-section of the second through hole 6302, thereby increasing the capillary force that the second through hole 6302 can generate. Even when air passes axially through the second through hole 6302, it cannot completely drain the liquid in the second through hole 6302, further improving the reliability of the independent air guiding element and better preventing the liquid from leaking from the second through hole 6302.

[0057] As Figure 2 shown, the first side hole 6503 is a slit extending from the bottom to the top of the buffer tube 6502. Such an arrangement can facilitate the formation of the first side hole 6503 and reduce the manufacturing cost.

[0058] As Figure 1 shown, the buffer tube 6502 and the sleeve 6501 can be formed separately and then assembled together, or can be integrally formed.

[0059] In this embodiment, the first through hole 6301 is arranged inside the core body 640, or the first through hole 6301 is arranged between the core body 640 and the sleeve 6501. As Figure 3 shown, preferably, the first through hole 6301 is arranged inside the core body 640, that is, the first through hole 6301 axially penetrating the air guiding assembly refers to the first through hole 6301 axially penetrating the core body 640. In the present invention, the core body 640 can be made of plastic or metal, but is preferably a porous capillary material, such as porous plastic, porous metal, porous bonded fiber, etc.

[0060] In the present invention, the maximum inscribed circle diameter of the minimum cross-section of the first through hole 6301 is preferably set to be from 0.2 mm to 2.0 mm, such as 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. Thus, the first through hole 6301 can also be formed as a capillary tube, can also generate capillary force and play a role in liquid sealing, so that a relatively high negative pressure can be generated in the liquid storage element 100 of the aerosol cartridge 800, and effectively prevent the liquid in the liquid storage element 100 from leaking.

[0061] Second Embodiment

[0062] Figure 4 is a schematic cross-sectional structure diagram of an independent air guiding element according to the second embodiment of the present invention; Figure 5 is according to Figure 4 the schematic cross-sectional structure diagram of the independent air guiding element at B - B. In this embodiment, Figure 4 the schematic cross-sectional structure diagram at A - A of Figure 2The same. This embodiment is similar in structure to the first embodiment, and the parts that are the same as those in the first embodiment will not be described again in the description of this embodiment.

[0063] The difference between this embodiment and the first embodiment is that, as Figure 5 shown, the first through-hole 6301 is provided between the core body 640 and the sleeve 6501. That is to say, the outer peripheral wall of the first through-hole 6301 includes a part of the core body 640. In the present invention, the outer peripheral wall of the first through-hole 6301 is either entirely composed of the core body 640 or at least part of the outer peripheral wall of the first through-hole 6301 is composed of the core body 640.

[0064] In this embodiment, part of the outer peripheral wall of the first through-hole 6301 is composed of the core body 640. Specifically, a plurality of support plates 6505 can be axially provided on the inner peripheral wall of the sleeve 6501. The support plates 6505 extend from the inner peripheral wall of the sleeve 6501 towards the center of the core body 640, for supporting the core body 640 and forming a plurality of separated first through-holes 6301 between the core body 640 and the sleeve 6501. In this embodiment, the first through-hole 6301 axially penetrating the air guiding assembly refers to that the first through-hole 6301 is provided between the sleeve 6501 and the core body 640.

[0065] The maximum inscribed circle diameter of the minimum cross-section of the first through-hole 6301 is preferably set to be 0.2 mm to 2.0 mm. Thus, the first through-hole 6301 can also be formed into a capillary tube, and can also generate capillary force and play a liquid sealing role, so that a relatively high negative pressure can be generated in the liquid storage element 100 of the aerosol cartridge 800, and the liquid in the liquid storage element 100 can be effectively prevented from leaking.

[0066] Third Embodiment

[0067] Figure 6 FIG. is a schematic cross-sectional structure diagram of an independent air guiding element according to the third embodiment of the present invention. Figure 7 For Figure 6 the cross-sectional structure diagram of the independent air guiding element at A-A. In this embodiment, Figure 6 the cross-sectional structure diagram of the independent air guiding element at B-B of Figure 3 is the same as

[0068] As Figure 6As shown, in this embodiment, preferably, the first side hole 6503 is provided on the peripheral wall of the buffer tube 6502. The first side hole 6503 is one or more openings on the peripheral wall of the buffer tube 6502, and the bottom of the first side hole 6503 is preferably located at the junction of the buffer tube 6502 and the sleeve 6501. With this structure, the liquid in the liquid storage element 100 can come into contact with the core 640 immediately after passing through the first side hole 6503, which is beneficial for the independent air guiding element 600 to play its role faster.

[0069] In this embodiment, a plurality of partition plates 6504 are axially arranged on the inner peripheral wall of the buffer tube 6502, and preferably 4 partition plates 6504 are provided.

[0070] Fourth Embodiment

[0071] Figure 8 It is a schematic cross-sectional structure diagram of an independent air guiding element according to the fourth embodiment of the present invention. In this embodiment, Figure 8 The cross-sectional structure diagram at A-A of Figure 2 or Figure 7 is the same, Figure 8 The cross-sectional structure diagram at B-B of Figure 3 is the same. This embodiment is similar to the first embodiment, and the same parts as the first embodiment will not be described in detail in the description of this embodiment.

[0072] In this embodiment, a second side hole 6506 is provided on the peripheral wall of the sleeve 6501, and the second side hole 6506 communicates with the core 640.

[0073] As Figure 8 shown, in this embodiment, a second side hole 6506 is provided on the peripheral wall of the sleeve 6501. The second side hole 6506 is one or more openings on the peripheral wall of the sleeve 6501, and the top of the second side hole 6506 is preferably located at the junction of the buffer tube 6502 and the sleeve 6501. This structure can enable the liquid in the liquid storage element 100 to come into contact with the core 640 more quickly, which is beneficial for the independent air guiding element 600 to play its role faster.

[0074] The second side hole 6506 is a slit formed by extending downward from the top of the sleeve 6501. Such a setting can make the second side hole 6506 easy to form and have a low manufacturing cost.

[0075] In this embodiment, when [[ID= The cross-sectional structure diagram at A-A of ​When they are the same, preferably, a first side hole 6503 is provided on the peripheral wall of the buffer tube 6502, and at the same time, a second side hole 6506 is provided on the peripheral wall of the sleeve 6501. The first side hole 6503 is preferably a slit extending towards the top of the buffer tube 6502. Of course, the first side hole 6503 on the buffer tube 6502 can also be provided as one or more openings on the peripheral wall of the buffer tube 6502. With this structure, the core body 640 can contact the liquid in the liquid storage element 100 through the first side hole 6503, and can also contact the liquid in the liquid storage element 100 through the second side hole 6506. Thus, the liquid sealing requirements of different aerosol cartridges 800 for the independent air guiding element 600 can be met, and the liquid leakage prevention effect can be improved.

[0076] In this embodiment, another implementation manner may be that the central axis of the first through hole 6301 is parallel to the central axis of the core body 640, but they do not coincide. This setting can also meet the liquid sealing requirements of the independent air guiding element 600, and at the same time enables the aerosol cartridge 800 to have a diversified design.

[0077] The fifth embodiment

[0078] ​ is a schematic cross-sectional structure diagram of an independent air guiding element according to the fifth embodiment of the present invention; ​ is according to ​ the first cross-sectional structure diagram of the independent air guiding element at A - A; ​ is according to ​ the second cross-sectional structure diagram of the independent air guiding element at A - A; ​ is according to ​ the third cross-sectional structure diagram of the independent air guiding element at A - A; ​ is according to ​ the cross-sectional structure diagram of the independent air guiding element at B - B. This embodiment is similar to the first embodiment, and the same parts as the first embodiment will not be described again in the description of this embodiment.

[0079] As ​ shown, the independent air guiding element 600 includes an air guiding assembly and a buffer tube 6502. The air guiding assembly includes a sleeve 6501, a core body 640 inserted into the sleeve 6501, and at least one first through hole 6301 axially penetrating the air guiding assembly. The buffer tube 6502 includes at least one second through hole 6302 axially penetrating the buffer tube 6502. The sleeve 6501 and the buffer tube 6502 are communicated, and the second through hole 6302 is communicated with the core body 640.

[0080] The central axis of the first through hole 6301 is parallel to the central axis of the core body 640, but they do not coincide.

[0081] The outlet of the first through hole 6301 on the upper end face of the air guiding component is at least partially located outside the projection of the buffer tube 6502 on the upper end face of the air guiding component.

[0082] That is to say, in this embodiment, the outlet of the first through hole 6301 on the upper end face of the air guiding component can be completely located outside the projection of the buffer tube 6502 on the upper end face of the air guiding component, or can be only partially located outside the projection of the buffer tube 6502 on the upper end face of the air guiding component, so as to meet the design requirements of different aerosol cartridges 800.

[0083] In this embodiment, it is preferred that the first through hole 6301 and the second through hole 6302 are not directly connected, but the second through hole 6302 is always in communication with the core body 640.

[0084] When the independent air guiding element 600 of the present invention is installed in the aerosol cartridge 800, the upper end face of the sleeve 6501 is flush with the bottom of the liquid storage element 100 of the aerosol cartridge 800.

[0085] In this embodiment, the first side hole 6503 and the second side hole 6506 can be not provided, thus, the structure of the independent air guiding element 600 can be simplified. However, according to the design requirements of liquid sealing, the first side hole 6503 can be added, or the second side hole 6506 can be added. The first side hole 6503 and the second side hole 6506 can also be added simultaneously.

[0086] In this embodiment, 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, such as 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, 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 is formed into a capillary tube, which can generate a relatively large capillary force, so that the liquid in the buffer tube 6502 is not easy to flow out.

[0087] As ​ shown, one or more partition plates 6504 can also be arranged axially on the inner peripheral wall of the buffer tube 6502.

[0088] As ​ shown, a plurality of partition plates 6504 can be arranged axially on the inner peripheral wall of the buffer tube 6502. At the same time, the first side hole 6503 can be arranged on the peripheral wall of the buffer tube 6502. The partition plates 6504 are preferably arranged in one or three.

[0089] As​ As shown, when the size of the independent air guiding element 600 is small, the buffer tube 6502 may not be provided with a partition plate 6504, but a first side hole 6503 is provided. The first side hole 6503 is a slit extending towards the top of the buffer tube 6502.

[0090] As ​ shown, in this embodiment, the first through hole 6301 axially penetrating the air guiding assembly is preferably such that the first through hole 6301 axially penetrates the core body 640.

[0091] Sixth Embodiment

[0092] ​ FIG. is a schematic cross-sectional structure diagram of an independent air guiding element according to the sixth embodiment of the present invention; ​ According to ​ the schematic cross-sectional structure diagram of the independent air guiding element at B-B. In this embodiment, ​ the schematic cross-sectional structure diagram at A-A of ​ or ​ is the same. This embodiment is similar in structure to the fifth embodiment, and the same parts as the fifth embodiment will not be described in detail in the description of this embodiment.

[0093] In this embodiment, the outlet of the first through hole 6301 on the upper end surface of the sleeve 6501 is located outside the projection of the buffer tube 6502 on the upper end surface of the sleeve 6501, and a first side hole 6503 is provided on the peripheral wall of the buffer tube 6502. The first side hole 6503 is one or more openings on the peripheral wall of the buffer tube 6502, and the bottom of the first side hole 6503 is preferably located at the junction of the buffer tube 6502 and the sleeve 6501.

[0094] A plurality of partition plates 6504 may be axially provided on the inner peripheral wall of the buffer tube 6502. When the size of the independent air guiding element 600 is small, the buffer tube 6502 may not be provided with a partition plate 6504.

[0095] As ​ shown, in this embodiment, the first through hole 6301 may be a groove provided on the side wall of the core body 640, that is, the peripheral wall of the first through hole 6301 is composed of the inner peripheral wall of the sleeve 6501 and a part of the core body 640.

[0096] In this embodiment, the lower end surface of the sleeve 6501 is flush with the lower end surface of the first through hole 6301. After the aerosol bomb 800 is assembled, this structure can enable the buffer body 843 to more effectively seal the lower outlet of the first through hole 6301, effectively preventing the situation where external air directly enters the first through hole 6301 without passing through the buffer body 843.

[0097] Seventh Embodiment

[0098] The aerosol bomb according to the present invention includes the independent air guiding element 600 of any one of the above. ​ For use ​ Schematic cross-sectional structure diagram of the aerosol bomb with the shown independent air guiding element. As ​ shown, in this embodiment, it is preferably to use the independent air guiding element 600 as ​ shown.

[0099] In this embodiment, the aerosol bomb 800 further includes an atomization core 930, a liquid storage element 100 for supplying liquid to the atomization core 930, and a buffer body 843. One end of the independent air guiding element 600 having the second through hole 6302 communicates with the liquid storage element 100, the other end of the independent air guiding element 600 communicates with the buffer body 843, and the independent air guiding element 600 communicates with the external atmosphere through the buffer body 843.

[0100] In the present invention, the independent air guiding element 600 communicates with the external atmosphere through the buffer body 843. When the liquid in the liquid storage element 100 is atomized and consumed, the external atmosphere supplies air to the liquid storage element 100 through the independent air guiding element 600. When the external temperature or pressure changes, for example, during air transportation or when the temperature rises, the liquid leaked 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 return to the liquid storage element 100 through the independent air guiding element 600.

[0101] In the present invention, one end of the independent air guiding element 600 communicating with the buffer body 843 locally compresses the buffer body 843. Thereby, the density near the contact part between the buffer body 843 and the independent air guiding element 600 can be increased, which is beneficial to forming a liquid seal at the air inlet port where the independent air guiding element 600 communicates with the buffer body 843, improving the reliability of the liquid seal in the first through hole 6301, and thus increasing the reliability of the independent air guiding element 600 to control air guiding. It is also beneficial to the enrichment of the liquid temporarily stored in the buffer body 843 near the part where the buffer body 843 contacts the independent air guiding element 600, so that the liquid in the buffer body 843 can be effectively recovered to the liquid storage element 100. The buffer body 843 is preferably bonded fiber, non-woven fabric or sponge.

[0102] The aerosol bomb 800 further includes an aerosol bomb housing 810, a second housing base 824 provided at the bottommost part of the aerosol bomb housing 810, a first housing base 823 provided inside the aerosol bomb housing 810 and spaced from the second housing base 824, and a buffer chamber 828 provided between the first housing base 823 and the second housing base 824. The buffer body 843 is located in the buffer chamber 828.

[0103] Specifically, in the present invention, as​ As shown, preferably, the aerosol bomb housing 810 forms a cavity with an opening at the bottom. The top of the aerosol bomb 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 bomb housing 810 and together with the aerosol bomb housing 810 forms a liquid storage element 100. An installation interval for installing the atomization 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 is simultaneously used as an aerosol passage 1303. The upper part of the atomization core 930 is tightly fitted and sealed with the connection port 1302 at the lower part of the aerosol passage 1303, and the lower part of the atomization core 930 is tightly fitted and sealed with the atomization core assembly port 826 in the middle of the first housing base 823. The buffer tube 6502 and the sleeve 6501 of the independent air guiding element 600 can be integrally formed with the first housing base 823. The second housing base 824 is arranged at an interval from the first housing base 823, used to seal the bottom opening of the aerosol bomb housing 810, and 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. The buffer body 843 can prevent the liquid from flowing freely in the buffer chamber 828, thereby preventing the liquid from leaking to the outside of the aerosol bomb. One end of the independent air guiding element 600 communicates with the liquid storage element 100, and the other end communicates with the buffer body 843. One end of the independent air guiding element 600 that communicates with the buffer body 843 locally compresses the buffer body 843, increasing the density near the contact part between the buffer body 843 and the independent air guiding element 600.

[0104] In this embodiment, the aerosol bomb 800 includes a separation tube 829. The separation tube 829 communicates with the base through hole 1122 of the aerosol bomb 800 and extends towards the atomization core 930. The separation tube 829 can, together with the second housing base 824, form a groove at the bottom of the second housing base 824, which can effectively prevent the atomized liquid in the buffer chamber 828 from leaking out of the aerosol bomb 800 through the base through hole 1122.

[0105] In the present invention, the independent air guiding element 600 is arranged on the first housing base 823. One end of the independent air guiding element 600 communicates with the liquid storage element 100, and the other end communicates with the buffer body 843 arranged in the buffer chamber 828. The liquid storage element 100 communicates with the buffer body 843 through the independent air guiding element 600 and communicates with the external atmosphere through the air guiding hole 827 of the separation tube 829, the separation tube 829 and the base through hole 1122. The external atmosphere enters the liquid storage element 100 through the base through hole 1122, the separation tube 829, the air guiding hole 827, the buffer body 843 and the independent air guiding element 600, thereby realizing the connection between the liquid storage element 100 and the external atmosphere through the independent air guiding element 600.

[0106] In another embodiment (not shown), one end of the isolation tube 829 is connected to the second housing base 824, and the other end of the isolation tube 829 abuts against the lower end of the atomization core 930. Thus, the isolation tube 829 can further effectively prevent the atomization liquid in the buffer chamber 828 from leaking out of the aerosol cartridge 800 through the base through-hole 1122.

[0107] ​ is ​ an enlarged schematic view of the dashed box C in. As ​ shown, the atomization core 930 includes an atomization core housing 9324, an outer housing liquid guiding through-hole 9325 provided on the atomization core housing 9324, and an atomization core liquid guiding element 932 blocking the outer housing liquid guiding through-hole 9325. The height of the top of the independent air guiding element 600 from the bottom of the liquid storage element 100 is not lower than the height of the top of the outer housing liquid guiding through-hole 9325 from the bottom of the liquid storage element 100.

[0108] When the aerosol cartridge 800 is operating, the atomization core liquid guiding element 932 contacts the liquid in the liquid storage element 100 through the outer housing liquid guiding through-hole 9325. When the aerosol cartridge 800 is inverted, this structure can keep the second through-hole 6302 in contact with the liquid all the time before the atomization core liquid guiding element 932 separates from the liquid surface, and can conduct the liquid to the core body 640 through capillary force, so that when the aerosol cartridge 800 is inverted, the liquid seal in the first through-hole 6301 can also be maintained.

[0109] In the aerosol cartridge 800 of the present invention, preferably, the bottom of the first side hole 6503 is flush with the bottom of the liquid storage element 100. Thus, before the liquid is exhausted, the liquid in the aerosol cartridge 800 can always enter the independent air guiding element 600 through the first side hole 6503.

[0110] In the present invention, the independent air guiding element 600 is independent of the atomization core liquid guiding element 932, that is, the atomization core liquid guiding element 932 does not participate in forming the peripheral wall of the first through-hole 6301. Different from the air guiding channel formed by the participation of the atomization core liquid guiding element in the prior art, the atomization core liquid guiding element 932 in the present invention does not participate in forming the air guiding channel of the independent air guiding element 600, and the independent air guiding element 600 does not participate in supplying liquid to the atomization core 930 either.

[0111] In the aerosol cartridge 800, the independent air guiding element 600 can be provided as one or more.

[0112] After the aerosol cartridge 800 is assembled, after the independent air guiding element 600 absorbs enough liquid, the first through-hole 6301 is sealed by liquid. After the buffer body 843 absorbs part of the liquid from the independent air guiding element 600, the air inlet port communicating the independent air guiding element 600 and the buffer body 843 is further sealed by liquid, increasing the reliability of the independent air guiding element 600 in controlling air guiding.

[0113] In the present invention, the liquid storage element 100 is a component for storing the atomized liquid. Different liquids can be stored therein according to the application purpose, such as e-cigarette oil, CBD solution, drug solution, etc.

[0114] For the aerosol cartridge 800 according to the present invention, even if the aerosol cartridge 800 is sucked to a high temperature and immediately placed upside down or sideways, and exactly when the independent air guiding element 600 is separated from the liquid in the liquid storage element 100, and part of the liquid guiding element 932 of the atomization core still contacts the liquid, during the cooling process of the aerosol cartridge 800, the negative pressure generated will suck the liquid in the first through hole 6301 empty. However, since the second through hole 6302 is communicated with the core body 640, the liquid stored in the second through hole 6302 can be conducted to the core body 640, thereby restoring the liquid seal in the first through hole 6301 and avoiding the disappearance of the negative pressure in the aerosol cartridge 800 and causing the liquid to leak from the atomization core 930.

[0115] In addition, after the outside air passes through the first through hole 6301, it can enter the liquid storage element 100 from the first side hole 6503 of the independent air guiding element 600, avoiding the situation that when the air axially passes through the second through hole 6302, the liquid in the second through hole 6302 is emptied and the independent air guiding element 600 fails. A partition plate 6504 is axially arranged in the second through hole 6302, which can improve the capillary force of the second through hole 6302. Moreover, even when the air axially passes through the second through hole 6302, it cannot empty all the liquid in the second through hole 6302, further improving the reliability of the independent air guiding element 600.

[0116] The present invention reduces the risk of liquid leakage of the aerosol cartridge 800 in extreme cases. The aerosol cartridge atomizes stably and can make the liquid be utilized efficiently, thereby effectively avoiding the waste of the atomized liquid.

[0120] In the aerosol bomb 800 of the present invention, preferably, the bottom of the second side hole 6506 is flush with the bottom of the liquid storage element 100. Thus, before the liquid is exhausted, the liquid in the aerosol bomb 800 can always enter the independent air guiding element 600 through the second side hole 6506.

The outlet of the first through hole 6301 on the upper end surface of the air guiding assembly is at least partially outside the projection of the buffer tube 6502 on the upper end surface of the air guiding assembly.

[0124] That is to say, in this embodiment, the outlet of the first through hole 6301 on the upper end surface of the air guiding assembly can be completely outside the projection of the buffer tube 6502 on the upper end surface of the air guiding assembly, or only partially outside the projection of the buffer tube 6502 on the upper end surface of the air guiding assembly, to meet the design requirements of different aerosol bombs 800.

[0125] In this embodiment, preferably, the first through hole 6301 and the second through hole 6302 are not directly connected, but the second through hole 6302 always remains connected to the core body 640.

[0126] In this embodiment, preferably, the upper end surface of the sleeve 6501 is flush with the bottom of the liquid storage element 100 of the aerosol bomb 800. Thus, before the liquid in the liquid storage element 100 is exhausted, the liquid in the liquid storage element 100 can always enter the independent air guiding element 600 through the outlet of the first through hole 6301 on the upper end surface of the sleeve 6501.
