Description

Aerosol cartridge and atomization device TECHNICAL FIELD

[0001] The present application relates to an aerosol cartridge and an atomization device, in particular to an aerosol cartridge and an atomization device with a separate air guide element for applications such as electronic cigarettes and atomization of medicinal solutions. BACKGROUND

[0002] Atomization technology is widely used in the field of electronic cigarettes and the like. A common technology in electronic cigarettes is to heat the liquid guide element of the atomization core in direct communication with the tobacco tar to atomize the liquid.

[0003] In a conventional aerosol cartridge, the atomization liquid is stored in a liquid storage element made of porous material, and the liquid in the porous material is transmitted to the liquid guide element of the atomization core through the liquid guide through hole on the atomization core shell 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, but as the liquid in the porous material is released, the ability of the porous material to release liquid continues to decline, resulting in a decline in atomization and taste, affecting the consumer experience.

[0004] In another aerosol cartridge, the atomization liquid is stored in a liquid storage element formed by the aerosol cartridge shell, and the liquid is difficult to be recovered when it leaks, which can easily cause waste of liquid or leakage of liquid in the aerosol cartridge to the outside.

[0005] SUMMARY

[0006] To solve the problems existing in the prior art, the present application provides an aerosol cartridge, which comprises an atomization core, a liquid storage element for supplying liquid to the atomization core, a separate air guide element communicating with the liquid storage element and the external atmosphere, and a buffer body; one end of the separate air guide element communicates with the liquid storage element, the other end communicates with the buffer body, and the separate air guide element communicates with the external atmosphere through the buffer body; the separate air guide element comprises a separate air guide element core and at least one separate air guide element through hole axially penetrating the separate air guide element, and the separate air guide element core is made of porous capillary material.

[0007] Further, the end of the separate air guide element communicating with the buffer body partially compresses the buffer body.

[0008] Further, the buffer body is a bonded fiber, a non-woven fabric or a sponge.

[0009] Further, the density of the buffer body is 0.02-0.15 g / cm 3 .

[0010] Further, the volume of the buffer body is greater than 5% of the volume of the liquid storage element.

[0011] Further, the aerosol also comprises an aerosol shell, a second shell base arranged at the bottom of the aerosol shell, a first shell base arranged in the interior of the aerosol shell and spaced apart from the second shell base, and a buffer chamber arranged between the first shell base and the second shell base, and the buffer body is arranged in the buffer chamber.

[0012] Further, the independent air guide element through hole is arranged in the independent air guide element core, or the independent air guide element further comprises an independent air guide element sleeve arranged around the independent air guide element core, and an independent air guide element through hole axially penetrating the independent air guide element is formed between the independent air guide element core and the independent air guide element sleeve.

[0013] Further, the porous capillary material is porous bonded fiber or porous sintered plastic.

[0014] Further, the maximum diameter of the inscribed circle of the minimum cross section of the independent air guide element through hole is 0.2mm to 2.0mm.

[0015] Further, the aerosol comprises an isolation tube communicating with the through hole of the base of the aerosol and extending to the atomization core, and the central axis of the isolation tube is offset from the central axis of the atomization core.

[0016] The present application also provides an atomization device comprising the aerosol according to any one of the above.

[0017] According to the aerosol and the atomization device of the present application, the independent air guide element is in communication with the external atmosphere through the buffer body. When the external temperature or pressure changes, for example, during air travel or when the temperature rises, the liquid leaked from the liquid storage element can be absorbed and temporarily stored by the buffer body, and when the external temperature or pressure returns, or the liquid in the liquid storage element is consumed by atomization, most of the liquid temporarily stored in the buffer body can return to the liquid storage element through the independent air guide element. Thus, not only the risk of liquid leakage of the aerosol is reduced, but also the liquid is efficiently utilized, avoiding waste.

[0018] The aerosol and the atomization device of the present application are suitable for atomization of various liquids, such as atomization of electronic cigarette liquid, atomization of pharmaceutical solutions, etc. In order to make the above content of the present application more obvious and easy to understand, the preferred embodiments are described in detail below with reference to the accompanying drawings.

[0035] First Embodiment

[0036] Fig. 1 is a schematic diagram of the structure of an aerosol bomb according to the first embodiment of the present application; Fig. 2 is a schematic diagram of the first structure of the aerosol bomb shown in Fig. 1; Fig. 3 is a schematic diagram of the cross-sectional structure of an atomizing core shown in Fig. 1; Fig. 4 is a schematic diagram of the first cross section of a separate air guide element according to the first embodiment of the present application; Fig. 5 is a schematic diagram of the second cross section of a separate air guide element according to the first embodiment of the present application; Fig. 6 is a schematic diagram of the third cross section of a separate air guide element according to the first embodiment of the present application; and Fig. 7 is a schematic diagram of the fourth cross section of a separate air guide element according to the first embodiment of the present application.

[0037] As shown in Figs. 1 to 7, the aerosol bomb 800 according to the first embodiment of the present application includes an atomizing core 930, a liquid storage element 100 for supplying liquid to the atomizing core 930, a separate air guide element 600 for communicating the liquid storage element 100 with the outside atmosphere, and a buffer 843. One end of the separate air guide element 600 communicates with the liquid storage element 100, the other end of the separate air guide element 600 communicates with the buffer 843, and the separate air guide element 600 communicates with the outside atmosphere through the buffer 843; the separate air guide element 600 includes a separate air guide element core 640 made of porous capillary material and at least one separate air guide element through hole 630 axially penetrating the separate air guide element 600.

[0038] In the present application, the separate air guide element 600 communicates with the outside atmosphere through the buffer 843. When the liquid in the liquid storage element 100 is atomized and consumed, the outside atmosphere replenishes air to the liquid storage element 100 through the separate air guide element 600. When the outside temperature or pressure changes, for example, during air travel or when the air temperature rises, the liquid leaked from the liquid storage element 100 can be absorbed and temporarily stored by the buffer 843, and when the outside temperature or pressure returns or the liquid in the liquid storage element 100 is atomized and consumed, most of the liquid temporarily stored in the buffer 843 can return to the liquid storage element 100 through the separate air guide element 600.

[0039] In the present application, the independent air guiding element 600 locally compresses the buffer body 843 at one end of the buffer body 843. In this way, the density of the buffer body 843 near the contact position of the independent air guiding element 600 can be increased, which is beneficial to the formation of a liquid seal at the air guiding port of the independent air guiding element 600 and the buffer body 843, improves the reliability of the liquid seal in the through hole 630 of the independent air guiding element, and thus increases the reliability of the independent air guiding element 600 in controlling air guiding. In addition, the liquid temporarily stored in the buffer body 843 can be enriched near the contact position of the buffer body 843 and 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.

[0040] The buffer body 843 is preferably adhesive fiber, non-woven fabric or sponge. The density of the buffer body 843 is preferably 0.02-0.15 g / cm3. 3 , 0.02 g / cm3 3 , 0.035 g / cm3 3 , 0.05 g / cm3 3 , 0.07 g / cm3 3 , 0.1 g / cm3 3 , 0.12 g / cm3 3 , 0.15 g / cm3 3 The buffer body 843 with a density less than 0.02 g / cm3 3 is difficult to manufacture. When the density of the buffer body 843 is greater than 0.15 g / cm3 3 , most of the liquid stored therein is difficult to return to the liquid storage element 100 and is wasted. Preferably, the density of the buffer body 843 is 0.035-0.07 g / cm3 3 .

[0041] The volume of the buffer body 843 is greater than 5% of the volume of the liquid storage element 100. Preferably, the volume of the buffer body 843 is 10-50% of the volume of the liquid storage element 100. More preferably, the volume of the buffer body 843 is 15-30% of the volume of the liquid storage element 100. When the volume of the buffer body 843 is less than 5% of the volume of the liquid storage element 100, the liquid storage capacity is too small, which is easy to cause the liquid to leak out of the aerosol container 800. When the volume of the buffer body 843 is greater than 50%, the buffer body 843 not only occupies too much internal space of the aerosol container 800, but also can cause too much liquid temporarily stored in the buffer body 843 to be unable to return to the liquid storage element 100, thereby causing waste of the liquid to be atomized.

[0042] The aerosol bomb 800 further comprises an aerosol bomb shell 810, a second shell base 824 arranged at the bottom of the aerosol bomb shell 810, a first shell base 823 arranged inside the aerosol bomb shell 810 and spaced apart from the second shell base 824, a buffer chamber 828 arranged between the first shell base 823 and the second shell base 824, and a buffer body 843 arranged in the buffer chamber 828.

[0043] Specifically, in the present application, as shown in FIG. 1 and FIG. 2, preferably, the aerosol bomb shell 810 forms a cavity with an opening at the bottom, the top of the aerosol bomb shell 810 extends into the cavity to form a liquid storage element through hole 130, and the first shell base 823 is plugged into the cavity from the bottom of the aerosol bomb shell 810 to form a liquid storage element 100 together with the aerosol bomb shell 810. A mounting interval 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 simultaneously serves as an aerosol passage 1303, the upper part of the atomizing core 930 tightly fits and seals the connecting port 1302 at the lower part of the aerosol passage 1303, and the lower part of the atomizing core 930 tightly fits and seals the atomizing core assembly port 826 at the middle part of the first shell base 823. The first shell base 823 is formed with an independent air guide element mounting hole 660 penetrating through the first shell base 823 for mounting the independent air guide element 600. The second shell base 824 is arranged in spaced apart relationship with the first shell base 823 for sealing the opening at the bottom of the aerosol bomb shell 810 and forming a buffer chamber 828 between the first shell base 823 and the second shell base 824, in which a buffer body 843 is arranged. The buffer body 843 can prevent the liquid from flowing freely in the buffer chamber 828, thereby preventing the liquid from leaking outside the aerosol bomb. One end of the independent air guide element 600 is communicated with the liquid storage element 100, and the other end is communicated with the buffer body 843. The end of the independent air guide element 600 communicated with the buffer body 843 partially compresses the buffer body 843, so that the density of the buffer body 843 near the contact part of the independent air guide element 600 is increased.

[0044] Preferably, an elastic body (such as silicone) can be arranged between the upper part of the atomizing core 930 and the connecting port 1302 at the lower part of the aerosol passage 1303, and between the lower part of the atomizing core 930 and the atomizing core assembly port 826 of the first shell base, to increase the sealing effect of the connection between the atomizing core 930 and the aerosol passage and the first shell base. In this way, external air can be prevented from leaking into the liquid storage element 100 through the mounting part of the atomizing core 930, and it is ensured that external air can only enter the liquid storage element 100 through the independent air guide element 600.

[0045] In the present embodiment, the aerosol bomb 800 comprises an isolation tube 829, which is communicated with the bottom hole 1122 of the base of the aerosol bomb 800 and extends to the atomizing core 930. One end of the isolation tube 829 is connected with the second shell base 824, and the other end of the isolation tube 829 is close to the atomizing core 930. The isolation tube 829 can effectively prevent the atomizing liquid in the buffer chamber 828 from leaking out of the aerosol bomb 800 through the bottom hole 1122.

[0046] In the present application, the independent air guide element 600 is arranged on the first shell base 823. One end of the independent air guide element 600 is communicated with the liquid storage element 100, and the other end of the independent air guide element 600 is communicated with the buffer body 843 arranged in the buffer chamber 828. The liquid storage element 100 is communicated with the buffer body 843 through the independent air guide element 600, and is communicated with the external atmosphere through the air guide hole 827 of the isolation tube 829, the isolation tube 829 and the bottom hole 1122. The external atmosphere enters the liquid storage element 100 through the bottom hole 1122, the isolation tube 829, the air guide hole 827, the buffer body 843 and the independent air guide element 600, thereby realizing the communication between the liquid storage element 100 and the external atmosphere through the independent air guide element 600.

[0047] As shown in FIG. 3, the atomizing core 930 comprises a tubular atomizing core shell 9324, a tubular atomizing core liquid guide element 932 closely attached to the inner circumferential wall of the atomizing core shell 9324, an atomizing core liquid guide element through hole 932b axially penetrating through the atomizing core liquid guide element 932, and a heating element 931 attached to the inner circumferential wall of the atomizing core liquid guide element 932.

[0048] The atomizing core shell 9324 is provided with a shell liquid guide through hole 9325, and the atomizing core liquid guide element 932 blocks the shell liquid guide through hole 9325 and contacts the liquid in the liquid storage element 100 through the shell liquid guide through hole 9325.

[0049] The atomizing core liquid guide element through hole 932b constitutes an atomizing chamber 934 at the position with the heating element 931. The shell liquid guide through hole 9325 of the atomizing core 930 can be formed by hollowing out the atomizing core shell 9324.

[0050] In the present application, the atomizing core 930 further comprises a lead wire 933 connected with the heating element 931, and the lead wire 933 is connected with the main machine in the atomizing device 1. The lead wire 933 can also be fixed on the atomizing core base 935. Preferably, the atomizing core base 935 is arranged in the atomizing core shell 9324 and below the atomizing core liquid guide element 932.

[0051] The aerosol bomb electrode 936 can be arranged on the aerosol bomb 800, one end of the aerosol bomb electrode 936 is connected with the lead wire 933 by welding, riveting or crimping, and the other end of the aerosol bomb electrode 936 is connected with the main machine electrode 954 in the atomizing device 1 by plugging, sheet riveting or magnetic attraction contact.

[0052] In the present application, the independent air guide element 600 is independent of the atomizing core liquid guide element 932, i.e. the atomizing core liquid guide element 932 does not participate in forming the peripheral wall of the independent air guide element through hole 630. Different from the air guide passage formed by the atomizing core liquid guide element in the prior art, the atomizing core liquid guide element 932 in the present application does not participate in forming the air guide passage of the independent air guide element 600, and the independent air guide element 600 also does not participate in providing liquid to the atomizing core 930.

[0053] In the aerosol 800, the independent air guide element 600 can be provided as one or more.

[0054] In the present application, the independent air guide element through hole 630 serves as the only air guide passage for guiding air from the outside to the liquid storage element 100.

[0055] The independent air guide element 600 can further include an independent air guide element sleeve 650 arranged on the outer periphery of the independent air guide element core 640, for mounting the independent air guide element core 640.

[0056] As shown in FIG. 4, the independent air guide element through hole 630 can be arranged in the independent air guide element core 640.

[0057] Alternatively, the independent air guide element 600 includes an independent air guide element core 640 and an independent air guide element sleeve 650 arranged on the outer periphery of the independent air guide element core 640, and an independent air guide element through hole 630 axially penetrating the independent air guide element 600 is formed between the independent air guide element core 630 and the independent air guide element sleeve 650. As shown in FIG. 5, a plurality of notches are formed on the outer peripheral wall of the independent air guide element core 640, thereby forming the independent air guide element through hole 630 between the independent air guide element core 640 and the independent air guide element sleeve 650; or as shown in FIG. 6, the independent air guide element core 640 is embedded in the independent air guide element sleeve 650 with reinforcing ribs, thereby forming the independent air guide element through hole 630 between the independent air guide element core 640 and the independent air guide element sleeve 650; or as shown in FIG. 7, there is a gap between the independent air guide element core 640 and the independent air guide element sleeve 650, thereby forming the independent air guide element through hole 630 between the independent air guide element core 640 and the independent air guide element sleeve 650.

[0058] The independent air guiding element core 640 is preferably a porous capillary material, such as porous bonded fiber, porous sintered plastic, etc. The independent air guiding element core 640 made of a porous capillary material can store and release liquid, and can absorb and release liquid from the radial direction to the independent air guiding element hole 630, making the independent air guiding element 600 more stable and agile as an air switch to supplement air to the liquid storage element 100. More preferably, the independent air guiding element core 640 is made of a fiber bonded in a core-sheath structure. This fiber does not require the use of adhesive and can be bonded by heating, reducing the risk of harmful substances, and the liquid permeates the bonded fiber quickly, which is beneficial to improving the sensitivity of the independent air guiding element 600.

[0059] Preferably, the sheath layer of the core-sheath structure fiber is polyethylene, polypropylene, polybutylene succinate (PBS), copolymer of polybutylene adipate and polybutylene terephthalate (PBAT), copolyester of polyethylene terephthalate (Co-PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), or polyamide 6, etc.

[0060] The maximum inscribed circle diameter of the minimum cross section of the independent air guiding element hole 630 is 0.2mm to 2.0mm, such as 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.2mm, 1.5mm, 2.0mm, etc. When the viscosity of the atomized liquid is small or the required atomization amount is small, a smaller independent air guiding element hole 630 can be provided; when the viscosity of the atomized liquid is large or the required atomization amount is large, a larger independent air guiding element hole 630 can be provided. The cross section of the independent air guiding element hole 630 can be provided in various geometric shapes, such as circular, sector, circular ring, polygon, etc.

[0061] When the independent air guiding element 600 contacts the liquid, the liquid wets the independent air guiding element 600 and liquid seals the independent air guiding element hole 630 under the action of capillary force. The strength of the liquid seal depends on the viscosity and surface tension of the liquid, the material of the independent air guiding element core 640 and the independent air guiding element sleeve 650, and the size of the independent air guiding element hole 630, etc.

[0062] In the present application, the independent air guiding element 600 is connected to one end of the buffer 843 and partially compresses the buffer 843, so that the density of the buffer 843 near the contact part with the independent air guiding element 600 increases. After the airsoft gun 800 is assembled, the independent air guiding element hole 630 is liquid sealed after the independent air guiding element 600 absorbs enough liquid, and the buffer 843 further liquid seals the air inlet port connected to the independent air guiding element 600 after absorbing part of the liquid from the independent air guiding element 600, increasing the reliability of the independent air guiding element 600 in controlling air guiding.

[0063] In the present application, the liquid storage element 100 is a component for storing liquid to be atomized. Different liquids can be stored therein according to the purpose of application, such as electronic cigarette oil, CBD solution, drug solution, etc.

[0064] The liquid storage element 100 has a liquid storage element through hole 130 axially penetrating the liquid storage element 100. The liquid storage element through hole 130 can be used as an aerosol passage 1303 of the aerosol bullet 800. One end of the aerosol passage 1303 is an atomization module connecting port 1302 communicating with the atomization core 930, and the other end is an aerosol outlet 1301. The aerosol passage 1303 can be integrally formed with the liquid storage element 100, and the liquid storage element through hole 130 can be used as the aerosol passage 1303, or it can be separately made of plastic, metal, etc. and assembled into the aerosol bullet 800.

[0065] Figure 8 is a schematic diagram of the structure of an atomization device using the aerosol bullet shown in Figure 1. As shown in Figure 8, the atomization device 1 has any of the above-mentioned aerosol bullets 800.

[0066] In this embodiment, the atomization device 1 can be disposable or multi-use structure. The atomization device 1 further comprises a main machine shell 950 having an opening for assembling the aerosol bullet 800, a main machine battery 955 arranged in the main machine shell 950, and a main machine control circuit 956 arranged in the main machine shell 950. The lead wire 933 of the aerosol bullet 800 extends into the main machine shell 950 and is welded to the main machine control circuit 956. The aerosol bullet 800 is inserted into the main machine shell 950 and tightly sealed with the main machine shell 950.

The present embodiment is similar to the first embodiment, and the same parts as the first embodiment will not be described again in the description of the present embodiment.

[0069] In this embodiment, the aerosol bullet 800 further comprises a lower sealing assembly 87 for sealing the gap between the first shell base 823 and the second shell base 824. The lower sealing assembly 87 covers the bottom wall and the side wall of the second shell base 824 and is formed with a sealing column 871 sealing the aerosol electrode 936. The part of the lower sealing assembly 87 corresponding to the base through hole 1122 protrudes upward to form an isolation tube 829. The top of the isolation tube 829 is preferably formed as an arched top, and at least one air guide hole 827 is formed on the arched top.

[0070] The buffer body 843 is arranged at the bottom of the lower sealing assembly 87. The buffer body 843 comprises a top surface, a bottom surface and a side wall, and has a buffer body through hole 8431 accommodating the isolation tube 829 through the top surface and the bottom surface, and a relief groove 8432 formed on the side wall of the buffer body 843 to avoid the sealing column 871.

[0071] In the embodiment, one end of the independent air guide element 600 is communicated with the liquid storage element 100, and the other end is communicated with the buffer body 843. The independent air guide element 600 is communicated with the external atmosphere through the buffer body 843. The liquid leaked from the liquid storage element 100 due to changes in the external environment can be temporarily stored in the buffer body 843, and is recovered to the liquid storage element 100 by the independent air guide element 600 when the external environment recovers or the liquid is atomized and consumed, thereby improving the utilization rate of the liquid and reducing the risk of liquid leakage of the aerosol.

[0072] In the embodiment, the aerosol 800 further comprises a liquid injection port 841, a liquid injection port sealing element 842 and a sealing element fixing port 844. The liquid injection port 841 is used to supplement the liquid atomized in the liquid storage element 100, the liquid injection port sealing element 842 is used to block the liquid injection port 841, and the sealing element fixing port 844 is used to fix the liquid injection port sealing element 842.

[0073] In the embodiment, an atomization device is also provided. As shown in FIG. 11, the atomization device 1 has any one of the aerosols 800 described above. The aerosol electrode 936 is arranged on the aerosol 800, and one end of the aerosol electrode 936 is connected to the lead wire 933 by plugging, and the other end of the aerosol electrode 936 is connected to the host electrode 954 in the atomization device 1 by contact. In this way, the aerosol 800 can be easily separated from the atomization device 1. When the liquid in the aerosol 800 is used up, the aerosol 800 can be replaced or refilled with liquid and reused to save costs.

[0075] FIG. 12 is a structural schematic diagram of a mist emitting device according to the third embodiment of the present application. The embodiment is similar to the structure of the first embodiment, and the same parts as the first embodiment will not be described again in the description of the embodiment.

[0076] In the present embodiment, the aerosol 800 comprises an isolation tube 829 which communicates with the bottom hole 1122 of the aerosol 800 and extends to the atomizing core 930, and the central axis of the isolation tube 829 deviates from the central axis of the atomizing core. When so configured, when the atomizing core 930 leaks liquid in an extreme case, the liquid leaked from the atomizing core 930 can be prevented from directly dripping into the isolation tube 829. Moreover, since the isolation tube 829 can be arranged at one side of the buffer chamber 828, instead of being arranged at the center of the buffer chamber 828, the buffer body 843 is formed as a whole, and the isolation tube 829 does not need to be provided with a hole, so that the manufacturing of the buffer body 843 can be simplified. Preferably, there is a spacing between the projection of the atomizing core 930 on the upper surface of the second shell base 824 and the projection of the isolation tube 829 on the upper surface of the second shell base 824, so that the liquid leaked from the atomizing core 930 can be further prevented from directly dripping into the isolation tube.

[0077] Preferably, the aerosol 800 further comprises a lower sealing assembly 87 for sealing the gap between the first shell base 823 and the second shell base 824. The portion of the lower sealing assembly 87 corresponding to the bottom hole 1122 is upwardly protruding, forming the isolation tube 829. The top of the isolation tube 829 is preferably formed as an arched top, and at least one air guiding hole 827 is formed on the arched top.

[0078] In the present embodiment, the aerosol 800 comprises an isolation tube 829 which communicates with the bottom hole 1122 of the aerosol 800 and extends to the atomizing core 930, and the central axis of the isolation tube 829 deviates from the central axis of the atomizing core. When so configured, when the atomizing core 930 leaks liquid in an extreme case, the liquid leaked from the atomizing core 930 can be prevented from directly dripping into the isolation tube 829. Moreover, since the isolation tube 829 can be arranged at one side of the buffer chamber 828, instead of being arranged at the center of the buffer chamber 828, the buffer body 843 is formed as a whole, and the isolation tube 829 does not need to be provided with a hole, so that the manufacturing of the buffer body 843 can be simplified. Preferably, there is a spacing between the projection of the atomizing core 930 on the upper surface of the second shell base 824 and the projection of the isolation tube 829 on the upper surface of the second shell base 824, so that the liquid leaked from the atomizing core 930 can be further prevented from directly dripping into the isolation tube.

[0079] In the present embodiment, the aerosol 800 comprises an isolation tube 829 which communicates with the bottom hole 1122 of the aerosol 800 and extends to the atomizing core 930, and the central axis of the isolation tube 829 deviates from the central axis of the atomizing core. When so configured, when the atomizing core 930 leaks liquid in an extreme case, the liquid leaked from the atomizing core 930 can be prevented from directly dripping into the isolation tube 829. Moreover, since the isolation tube 829 can be arranged at one side of the buffer chamber 828, instead of being arranged at the center of the buffer chamber 828, the buffer body 843 is formed as a whole, and the isolation tube 829 does not need to be provided with a hole, so that the manufacturing of the buffer body 843 can be simplified. Preferably, there is a spacing between the projection of the atomizing core 930 on the upper surface of the second shell base 824 and the projection of the isolation tube 829 on the upper surface of the second shell base 824, so that the liquid leaked from the atomizing core 930 can be further prevented from directly dripping into the isolation tube.

[0080] In abnormal conditions, such as the air pressure in the cabin decreases or the temperature difference between indoor and outdoor during air travel, the air in the liquid storage element 100 expands, and the liquid is discharged from the liquid storage element 100 through the independent air guide element 600 and absorbed by the buffer body 843, thereby preventing the liquid discharged from the liquid storage element 100 from leaking from the aerosol bomb 800 due to the free flow of the liquid in the buffer chamber; when the external conditions return to normal, or the liquid in the liquid storage element 100 is consumed when the aerosol bomb 800 is used, the liquid in the buffer body 843 returns to the liquid storage element 100 through the independent air guide element 600.

[0081] The independent air guide element 600 partially compresses the buffer body 843 at one end connected to the buffer body 843, increases the density of the buffer body 843 near the contact part of the independent air guide element 600, and is beneficial to the enrichment of the temporarily stored liquid in the buffer body 843 near the contact part of the buffer body 843 and the independent air guide element 600, so that the liquid in the buffer body 843 is effectively recovered to the liquid storage element 100. At the same time, due to the increase of the density near the contact part of the buffer body 843 and the independent air guide element 600, the liquid seal is formed at the air inlet port of the independent air guide element 600 and the buffer body 843, the reliability of the liquid seal in the through hole 630 of the independent air guide element is improved, the reliability of the independent air guide element 600 in controlling air guide is increased, and the atomization process is more stable.

[0082] The present application not only reduces the risk of liquid leakage of the aerosol bomb 800, but also makes the atomization more stable and ensures efficient use of the liquid, avoiding waste.

[0083] The above embodiments of the present application are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed by the present application should be covered by the claims of the present application.
