Description

TECHNICAL FIELD

[0001] The present application relates to an aerosol, in particular to an aerosol used in electronic cigarettes and medicine atomization devices. BACKGROUND

[0002] The technology of atomizing liquid by heating is widely used in the field of electronic cigarettes and the like. The common technology in electronic atomization is to heat the atomization core gas-liquid exchange element in direct communication with the tobacco tar, such as a glass fiber bundle or a cotton fiber bundle passing through the atomization chamber cavity, so as to atomize the liquid. It is necessary to properly match the atomization chamber cavity and the atomization core gas-liquid exchange element, so that the liquid is conducted from the atomization core gas-liquid exchange element while the external air enters the liquid storage element from the gap between the atomization core gas-liquid exchange element and the atomization chamber cavity. Since the glass fiber bundle and the cotton fiber bundle are soft and lack a fixed shape, it is difficult to precisely control the gap between the atomization core gas-liquid exchange element and the atomization chamber cavity. When the gap is too large, there is too much liquid on the atomization core, which will burst during atomization, and in severe cases, the liquid will leak. When the gap is too small, the air is difficult to enter the liquid storage element, which in turn causes the atomization core to lack liquid and the core to be clogged, which affects the stability of atomization and the consumer experience.

[0040] First Embodiment

[0041] Figure 1a This is a longitudinal cross-sectional schematic diagram of the aerosol cannon according to the first embodiment of the present invention; Figure 1b for Figure 1a A schematic diagram of the cross-section of the gas-liquid exchange element.

[0042] like Figure 1a As shown, the aerosol bullet 800 according to the first embodiment of the present invention includes a liquid storage element 100, an atomizing core 930, and a gas-liquid exchange element 290 connecting the liquid storage element 100 and the atomizing core 930. The atomizing core 930 is located below the gas-liquid exchange element 290. The gas-liquid exchange element 100 conducts liquid in the liquid storage element 100 to the atomizing core 930, and replenishes gas to the liquid storage element 100 through the gas-liquid exchange element 290.

[0043] The aerosol 800 further comprises an aerosol housing 810, an aerosol passage 1303 extending axially from the top of the aerosol housing 810 to the inside of the aerosol housing 810, and a housing base 112 provided at the bottom of the aerosol housing 810.

[0044] The liquid storage element 100 can be formed separately or can be formed by a space surrounded by the wall of the aerosol passage 1303 and the aerosol housing 810. The liquid storage element 100 can have a liquid storage element passage hole 130 extending axially through the liquid storage element 100, and the liquid storage element passage hole 130 can be used as the aerosol passage 1303 at the same time.

[0045] The opening of the liquid storage element 100 near the housing base 112 is blocked by the gas-liquid exchange element 290. When the aerosol passage 1303 is used as the liquid storage element passage hole 130 at the same time, one end of the aerosol passage 1303 passes through the gas-liquid exchange element 290 and tightly fits with the inner hole of the gas-liquid exchange element 290 to prevent liquid leakage. When the liquid storage element 100 is formed separately, the inner hole of the gas-liquid exchange element 290 tightly fits with the wall of the liquid storage element passage hole 130 to prevent liquid leakage.

[0046] When the aerosol housing 810 is used as the housing of the liquid storage element 100 at the same time, the outer peripheral wall of the gas-liquid exchange element 290 tightly fits with the inner peripheral wall of the aerosol housing 810. When the liquid storage element 100 is formed separately, the outer peripheral wall of the gas-liquid exchange element 290 tightly fits with the inner peripheral wall of the housing of the liquid storage element 100. One side of the gas-liquid exchange element 290 is in contact with the liquid in the liquid storage element 100, and the other side of the gas-liquid exchange element 290 is in direct or indirect contact with the atomizing core 930, thereby conducting the liquid in the liquid storage element 100 to the atomizing core 930.

[0047] A plastic perforated baffle (not shown) similar to the gas-liquid exchange element 290 but slightly smaller in size than the gas-liquid exchange element 290 can be installed in the opening of the liquid storage element 100 near the housing base 112 before the gas-liquid exchange element 290 is installed, and the plastic perforated baffle functions to position and support the gas-liquid exchange element 290.

[0048] In the present embodiment, the atomizing chamber 934 is a cavity in which the liquid is atomized, and the atomizing chamber 934 is formed by a space surrounded by the aerosol housing 810, the gas-liquid exchange element 290, and the housing base 112. The atomizing core 930 is provided in the atomizing chamber 934, and the housing base 112 has a housing base passage hole 1122 extending through the housing base 112, one end of the housing base passage hole 1122 being an air inlet 1121 communicating with the outside, and the outside air entering the atomizing chamber 934 through the air inlet 1121. The liquid is atomized by the atomizing core 930 in the atomizing chamber 934 and escapes from the aerosol 800 through the aerosol passage 1303 and the aerosol outlet 1301.

[0049] In the present embodiment, since the atomizing core 930 is located below the gas-liquid exchange element 290, the atomizing core 930 can be assembled on the shell base 112 first, and then inserted into the aerosol shell 810 together with the shell base 112 to complete the assembly, forming a detachable and reusable atomizing core 930. That is, the aerosol 800 according to the present embodiment can be integrated into two parts, the first part being the part including the shell base 112 and the atomizing core 930, and the second part being the part other than the first part. After the liquid in the liquid storage element 100 is consumed, the second part can be replaced to be used again. Since the first part is a structure that can be disassembled and assembled by simple insertion, the atomizing core 930 can be used multiple times, which can greatly save the use cost of consumers.

[0050] <Gas-liquid exchange element>

[0051] As shown in Figure 1b , the gas-liquid exchange element 290 is made of fibers to form a three-dimensional network structure. Preferably, a hot bonding method is used. The cross section of the gas-liquid exchange element 290 can be various geometric shapes, such as circular, oval, rectangular, etc. The density of the gas-liquid exchange element 290 of the present application is 0.035-0.3 g / cm 3 , for example, 0.035 / cm 3 , 0.050 / cm 3 , 0.065 / cm 3 , 0.080 / cm 3 , 0.100 / cm 3 , 0.125 / cm 3 , 0.150 / cm 3 , 0.175 / cm 3 , 0.200 / cm 3 , 0.225 / cm 3 , 0.250 / cm 3 , 0.275 / cm 3 , 0.300 / cm 3 , preferably 0.05-0.2 g / cm 3 . When the density is less than 0.035 g / cm 3 , the gas-liquid exchange element 290 is difficult to make and has insufficient strength, and is easy to deform or wrinkle during assembly, affecting the stability of atomization or causing liquid leakage. When the density is greater than 0.3 g / cm 3 , the gas-liquid exchange element 290 has insufficient ability to supplement gas to the liquid storage element 100, and the negative pressure in the liquid storage element 100 is too high to make the liquid difficult to be discharged.

[0052] In the present application, the capillary pressure of the gas-liquid exchange element 290 is 2mm-35mm, for example, 2mm, 3mm, 5mm, 7mm, 9mm, 11mm, 13mm, 15mm, 17mm, 20mm, 25mm, 30mm, 35mm. When the capillary pressure of the gas-liquid exchange element 290 is less than 2mm, the liquid in the liquid storage element 100 is prone to leakage. When the capillary pressure of the gas-liquid exchange element 290 is greater than 35mm, it is difficult for the gas to pass through the gas-liquid exchange element 290 into the liquid storage element 100, resulting in excessive negative pressure in the liquid storage element 100, making it difficult for the liquid in the liquid storage element 100 to be conducted to the atomizing core 930 through the gas-liquid exchange element 290, resulting in insufficient liquid content on the atomizing core 930 and affecting the atomization quality. Preferably, the capillary pressure of the gas-liquid exchange element 290 is 2.5mm to 25mm, more preferably 3mm-10mm. The gas-liquid exchange element 290 with appropriate capillary pressure can be selected according to different atomization requirements.

[0053] <fibers and bicomponent fibers>

[0054] The gas-liquid exchange element 290 is preferably made of bicomponent fibers 2 of a core-sheath structure. The bicomponent fibers 2 of the core-sheath structure can be concentric or eccentric. The bicomponent fibers 2 can be filaments or short fibers. The bicomponent fibers 2 can be selected according to the performance requirements of the gas-liquid exchange element 290 to make the gas-liquid exchange element 290. The melting point of the core layer of the bicomponent fibers 2 is higher than that of the sheath layer by more than 20℃, which can make the core layer maintain a certain rigidity when heat bonding between fibers, facilitating the making of the gas-liquid exchange element 290 with uniform voids.

[0055] Figure 1c is Figure 1b an enlarged cross-sectional view of the bicomponent fiber in Figure 1c As shown in Figure 1d is Figure 1b another enlarged cross-sectional view of the bicomponent fiber in Figure 1d As shown in

[0056] The sheath layer 21 of the bicomponent fiber 2 can be polyolefin, copolyester of polyethylene terephthalate (Co-PET for short), polytrimethylene terephthalate (PTT for short), polybutylene terephthalate (PBT for short), polylactic acid, polyamide-6, etc. Polyolefin is a general term for a class of thermoplastic resins obtained by polymerization or copolymerization of α-olefins such as ethylene, propylene, 1-butene, 1-pentene, 1-hexene, etc. alone.

[0057] The diameter of the bicomponent fiber 2 used to make the gas-liquid exchange element 290 is between 1.5 denier and 30 denier, preferably between 2 denier and 15 denier. The bicomponent fiber 2 with a core-sheath structure and a diameter between 2 denier and 15 denier is easy to make the gas-liquid exchange element 290. When the viscosity of the liquid to be atomized is low, it is appropriate to use a fiber with a smaller diameter to make the gas-liquid exchange element 290, such as a fiber with a diameter of 1.5 denier, 2 denier, or 3 denier. When the viscosity of the liquid to be atomized is high, it is appropriate to use a fiber with a larger diameter to make the gas-liquid exchange element 290, such as a fiber with a diameter of 6 denier, 10 denier, 15 denier, or 30 denier.

[0058] In this embodiment, the gas-liquid exchange element 290 is formed by thermally bonding bicomponent short fibers into a three-dimensional network structure. The sheath layer 21 is made of polyethylene, and the core layer 22 is made of polypropylene or PET. The density of the gas-liquid exchange element 290 is between 0.035 g / cm3 and 0.3 g / cm3 3 , preferably between 0.05 g / cm3 and 0.2 g / cm3 3 This gas-liquid exchange element 290 has good strength and good elasticity, and has a fast liquid conduction speed and the ability to supplement gas to the liquid storage element 100. This gas-liquid exchange element 290 can be used for atomizing electronic cigarette liquid and CBD liquid, etc.

[0059] In this embodiment, the sheath layer 21 of the bicomponent fiber 2 can be replaced with polypropylene, Co-PET, polyamide-6, PBT, or PTT, etc. The gas-liquid exchange element 290 made of these materials has higher temperature resistance.

[0060] <LIQUID STORAGE ELEMENT>

[0061] The liquid storage element 100 is a component for storing liquid in the gas cartridge 800. The liquid storage element 100 is filled with the liquid to be atomized. The liquid storage element 100 can be a hollow cavity made of plastic or metal, and can be filled with porous material for storing liquid. When in use, the liquid in the liquid storage element 100 is conducted to the atomizing core 930 through the gas-liquid exchange element 290 and is atomized when needed.

[0062] The gas cartridge 800 can be provided with a liquid injection hole (not shown) communicating with the inside of the liquid storage element 100, and a sealing plug (not shown) can be provided on the liquid injection hole. That is, the gas cartridge 800 can be provided with a liquid injection hole on the gas cartridge shell 810 at the position of the liquid storage element 100. When it is necessary to supplement liquid to the liquid storage element 100, the sealing plug is opened, the liquid is injected, and the sealing plug is reinserted into the liquid injection hole. The open type liquid injection structure of the gas cartridge 800 can further reduce the use cost of the gas cartridge 800.

[0063] <ATOMIZING CORE>

[0064] The atomizing core 930 is a component for atomizing liquid in the aerosol 800. Common atomizing cores 930 that can be used in the present application include a glass fiber bundle atomizing core 930 with a coiled heating wire, a cotton string atomizing core 930 with a coiled heating wire, a porous ceramic atomizing core 930 with a pre-embedded heating wire, a compressed cotton atomizing core 930 with a pre-embedded heating wire, a non-woven fabric-coated spiral heating wire atomizing core 930, and the like. The gas-liquid exchange element 290 in the present application can be in direct contact with the atomizing core 930 and conduct liquid from the liquid storage element 100 to the atomizing core 930. A relay liquid-conducting element 939 can also be added between the atomizing core 930 and the gas-liquid exchange element 290. In the present application, the relay liquid-conducting element 939 refers to a liquid-conducting element in the aerosol 800 that can transport liquid in the liquid storage element 100 to the atomizing core. Specifically, liquid in the liquid storage element 100 is conducted to the relay liquid-conducting element 939 through the gas-liquid exchange element 290, and the relay liquid-conducting element 939 then conducts the liquid to the atomizing core 930. In the present embodiment, the gas-liquid exchange element 290 is in direct contact with the atomizing core 930, and a non-woven fabric-coated spiral heating wire atomizing core 930 is preferably used.

[0065] In use, when the airflow enters through the air inlet 1121 of the housing base 112 and passes through the atomizing core 930, the atomizing core 930 is heated, the liquid on the atomizing core 930 is atomized, and the aerosol generated by atomization escapes through the aerosol passage 1303 and the aerosol outlet 1301. The liquid content on the atomizing core 930 decreases during atomization, and the gas-liquid exchange element 290 conducts liquid from the liquid storage element 100 to the atomizing core 930. As liquid in the liquid storage element 100 is conducted out for atomization, the negative pressure in the liquid storage element 100 increases. When the pressure difference between the liquid storage element 100 and the outside reaches a certain range, outside air enters the liquid storage element 100 through the gas-liquid exchange element 290.

[0066] The atomizing core 930 also includes a lead wire 933 connected to the lead wire pin 936 or a power source (not shown).

[0067] Second Embodiment

[0068] Figure 2a Longitudinal sectional view of the aerosol of the second embodiment disclosed in the present application; Figure 2b is a cross-sectional view of the gas-liquid exchange element in the Figure 2a is another cross-sectional view of the gas-liquid exchange element in the Figure 2c is another cross-sectional view of the gas-liquid exchange element in the Figure 2a The present embodiment is similar in structure 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] As Figure 2aAs shown, according to the second embodiment of the aerosol bomb, it comprises a liquid storage element 100, an atomizing core 930, and a gas-liquid exchange element 290 connecting the liquid storage element 100 and the atomizing core 930, the atomizing core 930 is located below the gas-liquid exchange element 290, the gas-liquid exchange element 100 conducts the liquid in the liquid storage element 100 to the atomizing core 930, and the gas is replenished to the liquid storage element 100 through the gas-liquid exchange element 290.

[0070] In this embodiment, the atomizing core 930 is made of porous ceramic with pre-embedded heating wire or compressed cotton with pre-embedded heating wire. In addition, the aerosol bomb also comprises a relay liquid guiding element 939, which can be a non-woven fabric covering the atomizing core 930. The relay liquid guiding element 939 can also be a tubular object made of bicomponent fiber 2, and the atomizing core 930 is inserted into the tubular relay liquid guiding element 939 and tightly contacts the inner wall of the relay liquid guiding element 939.

[0071] The liquid storage element 100 is formed by the space surrounded by the aerosol bomb shell 810, the wall part of the gas mist passage 1303, and the gas-liquid exchange element 290. The liquid storage element 100 can have a liquid storage element 100 through hole 130 axially penetrating the liquid storage element 100, which can also be used as the gas mist passage 1303, one end of the gas mist passage 1303 penetrates the gas-liquid exchange element 290 and tightly fits the inner hole of the gas-liquid exchange element 290 to prevent liquid leakage.

[0072] In this embodiment, the gas-liquid exchange element 290 is formed into a three-dimensional structure of a three-dimensional network by heat bonding of bicomponent fiber 2 with a core-sheath structure, the sheath layer 21 of the bicomponent fiber 2 is polyethylene, and the core layer 22 is polypropylene. The cross section of the gas-liquid exchange element 290 is circular, and the gas-liquid exchange element through hole 2903 axially penetrating the gas-liquid exchange element is arranged at the center. The gas-liquid exchange element 290 includes a high capillary part 2901 close to the center and a low capillary part 2902 away from the center but adjacent to the high capillary part 2901. The density of the low capillary part 2902 is 0.035-0.15 g / cm 3 , and the density of the high capillary part 2901 is 0.15-0.3 g / cm 3 . The densities of the high capillary part 2901 and the low capillary part 2902 can also be similar, both within the range of 0.035-0.3 g / cm 3 , but the high capillary part 2901 is made of fibers with smaller fineness, and the low capillary part 2902 is made of fibers with larger fineness. The capillary pressure of the low capillary part 2902 is 2 mm-35 mm, preferably 2.5 mm to 25 mm, and more preferably 3 mm to 10 mm. The low capillary part 2902 with appropriate capillary pressure can be selected according to different atomization requirements.

[0073] In this embodiment, if the high capillary portion 2901 and the low capillary portion 2902 are all wetted by the liquid, both the high capillary portion 2901 and the low capillary portion 2902 can conduct the liquid, but only the low capillary portion 2902 can conduct the gas.

[0074] The high capillary portion 2901 and the low capillary portion 2902 can be integrally formed or assembled together after being separately formed.

[0075] Preferably, the low capillary portion 2902 has a buffer space, which means that there is a part of the low capillary portion 2902 that is not wetted by the liquid during normal use. In this case, the thickness of the gas-liquid exchange element 290 is preferably greater than or equal to 1 mm, and most preferably greater than or equal to 2 mm, for example, 3 mm, 4 mm, and 5 mm. Those skilled in the art can determine the thickness of the gas-liquid exchange element 290 according to the space limitation of the aerosol cartridge 800, but in order to ensure the existence of the buffer space, the gas-liquid exchange element 290 must be at least 1 mm thick. In the case of normal use, if the high capillary portion 2901 is wetted by the liquid, but the low capillary portion 2902 is only partially wetted by the liquid, the buffer space will not be wetted, then the high capillary portion 2901 can conduct the liquid, and the low capillary portion 2902 can conduct the gas. In this case, the part of the low capillary portion 2902 that is not wetted by the liquid has a buffer space, which reduces the risk of liquid leakage from the aerosol cartridge. In the case of transportation or extreme environment, which causes the gas pressure to change sharply, the buffer space can temporarily store the excess liquid conducted in the liquid storage element 100, thereby effectively avoiding the risk of liquid leakage from the aerosol cartridge 800.

[0076] The outer peripheral wall of the gas-liquid exchange element 290 tightly fits the inner peripheral wall of the aerosol cartridge shell, one side of the gas-liquid exchange element 290 contacts the liquid in the liquid storage element 100, and the other side of the gas-liquid exchange element 290 contacts the relay liquid guide element 939. In use, the liquid in the liquid storage element 100 is conducted to the relay liquid guide element 939 through the gas-liquid exchange element 290, and the relay liquid guide element 939 conducts the liquid to the atomizing core 930. As the liquid in the liquid storage element 100 is conducted out for atomization, the negative pressure in the liquid storage element 100 increases. When the pressure difference between the liquid storage element 100 and the outside reaches a certain range, the outside air enters the liquid storage element 100 through the gas-liquid exchange element 290, so that the pressure in the liquid storage element 100 remains stable during atomization. The working principle of this embodiment is similar to that of the first embodiment.

[0077] In this embodiment, the aerosol cartridge 800 further comprises a condensed liquid absorption element 400, which is installed in the gas-liquid passage 1303 and can absorb the condensed liquid generated by the gas-liquid passage 1303, thereby improving the consumer experience.

[0078] In this embodiment, the aerosol cartridge 800 further comprises a silica gel gas-liquid passage cap 1304. As shown in FIG. 13B, the silica gel gas-liquid passage cap 1304 is installed on the gas-liquid passage 1303, and the silica gel gas-liquid passage cap 1304 is in contact with the condensed liquid absorption element 400. Figure 2aAs shown, the longitudinal section of the silica gel aerosol pipe cap 1304 is a reversed T-shaped tubular structure with a through hole axially penetrating the silica gel aerosol pipe cap 1304. The silica gel aerosol pipe cap 1304 is inserted into the aerosol passage 1303 from the aerosol inlet end of the aerosol passage 1303, the outer peripheral wall of the inserted part of the silica gel aerosol pipe cap 1304 abuts against the inner peripheral wall of the aerosol passage 1303, and the non-inserted end of the silica gel aerosol pipe cap 1304 abuts against the end of the aerosol passage 1303. The outer diameter of the non-inserted end of the silica gel aerosol pipe cap 1304 is greater than the outer diameter of the aerosol passage 1303, so that the non-inserted end of the silica gel aerosol pipe cap 1304 can support and position the gas-liquid exchange element 290. The silica gel is high-temperature resistant and can be stably used at the normal atomization temperature, so that the use of the silica gel aerosol pipe cap 1304 can reduce the requirement for the temperature resistance of the wall of the aerosol passage 1303, and can expand the selection range of the material for manufacturing the aerosol shell 810 and the wall of the aerosol passage 1303.

[0079] The silica gel aerosol pipe cap 1304 can also prevent the condensate absorbing element 400 from falling off from the aerosol passage 1303. In addition, a filtering part can be arranged at the aerosol inlet of the silica gel aerosol pipe cap 1304, which can be a filtering screen or a filtering baffle or a baffle plate (not shown) with holes, or a flow baffle arranged at the aerosol inlet, which can prevent large-particle atomized droplets from directly rushing upward into the aerosol passage 1303. When the flow baffle is used, the atomized aerosol needs to bypass the flow baffle to enter the aerosol passage 1303, which can effectively prevent large-particle atomized droplets from directly rushing upward into the aerosol passage 1303.

[0080] As shown in FIG. 13, the gas-liquid exchange element 290 can be arranged in the aerosol passage 1303. Figure 2a As shown in FIG. 13, the gas-liquid exchange element 290 can be arranged in the aerosol passage 1303.

[0081] As shown in FIG. 13, the gas-liquid exchange element 290 can be arranged in the aerosol passage 1303. Figure 2b As shown in FIG. 13, the gas-liquid exchange element 290 can be arranged in the aerosol passage 1303.

[0082] As shown in FIG. 13, the gas-liquid exchange element 290 can be arranged in the aerosol passage 1303. Figure 2c As shown in FIG. 13, the gas-liquid exchange element 290 can be arranged in the aerosol passage 1303.

The appropriate density and capillary pressure of the gas-liquid exchange element 290 can be selected according to different atomization requirements. The working principle of this embodiment is the same as that of the first embodiment.

[0095] In the fourth embodiment, the gas-liquid exchange element 290 has a low capillary part 2902 and a high capillary part 2901. The density of the low capillary part 2902 is 0.035-0.15 g / cm 3 , and the density of the high capillary part 2901 is 0.15-0.3 g / cm 3 . The capillary pressure of the low capillary part 2902 is 2-35 mm.

[0096] In the fourth embodiment, the aerosol 800 is provided with a liquid storage element 100, an atomizing core 930, and a gas-liquid exchange element 290 connecting the liquid storage element 100 and the atomizing core 930. The atomizing core 930 is located below the gas-liquid exchange element 290. The gas-liquid exchange element 100 conducts the liquid in the liquid storage element 100 to the atomizing core 930, and replenishes the gas to the liquid storage element 100 through the gas-liquid exchange element 290. Figure 4aIn the fourth embodiment of the aerosol cartridge shown, the liquid storage element 100 is a cavity made of plastic, into which liquid is injected.

The two ends of the glass fiber or cotton fiber bundle are bent and supported by the housing base 112, and contact the high capillary 2901 on the other side of the gas-liquid exchange element 290 through the atomizing chamber through hole 9341, or simultaneously contact the high capillary 2901 and low capillary 2902 on the other side of the gas-liquid exchange element 290.

[0097] A condensate absorption element 400 can be installed in the aerosol channel 1303 to absorb the condensate in the aerosol and improve the taste of the aerosol.

[0098] In such Figure 4b In another aerosol cartridge of the fourth embodiment shown, the radial dimension of the end of the liquid storage element through-hole 130 near the atomizing core 930 is larger than the rest of the liquid storage element through-hole 130, and a groove is formed in the housing base 112 at the portion corresponding to the liquid storage element through-hole 130. The end of the liquid storage element through-hole 130 with the larger radial dimension and the groove in the housing base 112 constitute the atomizing chamber 934. This structure is particularly suitable for aerosol cartridges 800 with a flat structure.

[0099] In this embodiment, the atomizing core 930 is a bundle of glass fiber or cotton fiber wound with an electric heating wire. The glass fiber or cotton fiber bundle extends out of the atomizing chamber 934 and is clamped between the housing base 112 and the gas-liquid exchange element 290.

The shape of the gas-liquid exchange element 290 can be selected to suit the shape design of different aerosol canisters 800.

[0101] During operation, the liquid on the atomizing core 930 is atomized. The gas-liquid exchange element 290 obtains liquid from the liquid storage element 100 and conducts it to the atomizing core 930. The negative pressure in the liquid storage element 100 increases, and gas is replenished to the liquid storage element 100 through the low capillary 2902. This process is repeated to ensure smooth atomization.
