First embodiment

FIG. 1a is a schematic longitudinal cross-sectional view of a first disclosed embodiment of an aerosol bomb; FIG. 1b is a schematic cross-sectional view of the gas-liquid exchange element of FIG. 1 a.

As shown in fig. 1a, the aerosol bomb 800 according to the first embodiment of the present invention comprises a liquid storage element 100, an atomizing core 930, and a gas-liquid exchange element 290 communicating the liquid storage element 100 and the atomizing core 930, wherein 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 supplemented to the liquid storage element 100 through the gas-liquid exchange element 290.

Aerosol projectile 800 further includes an aerosol projectile housing 810, an aerosol channel 1303 extending axially from the top of aerosol projectile housing 810 into aerosol projectile housing 810, and a housing base 112 disposed at the bottom of aerosol projectile housing 810.

The reservoir 100 may be formed separately or may be formed by the space enclosed by the aerosol shell 810 and the walls of the aerosol passage 1303. The reservoir member 100 may have a reservoir member through bore 130 extending axially through the reservoir member 100, and the reservoir member through bore 130 may simultaneously serve as the aerosol passage 1303.

The opening of the liquid storage component 100 close to the housing base 112 is blocked by the gas-liquid exchange component 290. When the aerosol channel 1303 is used as the through hole 130 of the liquid storage element, one end of the aerosol channel 1303 passes through the gas-liquid exchange element 290 and is tightly fitted with the inner hole of the gas-liquid exchange element 290 to prevent liquid leakage. When the reservoir 100 is formed separately, the inner bore of the gas-liquid exchange element 290 mates with the wall of the reservoir through bore 130 to prevent liquid leakage.

When the aerosol housing 810 is also used as the housing for the reservoir 100, the outer peripheral wall of the gas-liquid exchange element 290 mates with the inner peripheral wall of the aerosol housing 810. When the liquid storage member 100 is molded separately, the outer peripheral wall of the gas-liquid exchange member 290 is fitted closely to the inner peripheral wall of the casing of the liquid storage member 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 wick 930, thereby conducting the liquid in the liquid storage element 100 to the atomizing wick 930.

Before the gas-liquid exchange element 290 is installed, a hollow plastic baffle (not shown) may be installed in the opening of the liquid storage element 100 near the housing base 112, the plastic baffle has a shape similar to the gas-liquid exchange element 290 but a size slightly smaller than the gas-liquid exchange element 290, and the plastic baffle plays a role in positioning and supporting the gas-liquid exchange element 290.

In this embodiment, the aerosolization chamber 934 is a cavity in which the liquid is aerosolized, and the aerosolization chamber 934 is formed by the space enclosed by the aerosol cartridge housing 810, gas-liquid exchange element 290, and housing base 112. Set up atomizing core 930 in the atomizer 934, be provided with the casing base through-hole 1122 that runs through casing base 112 on the casing base 112, the one end of casing base through-hole 1122 and external intercommunication is as air inlet 1121, and outside air passes through air inlet 1121 and gets into atomizer 934. The liquid is atomized by atomizing core 930 in atomizing chamber 934 and exits aerosol can 800 through aerosol channel 1303 and aerosol outlet 1301.

In this embodiment, since the atomizing core 930 is located below the gas-liquid exchange element 290, the atomizing core 930 can be assembled on the housing base 112 and then inserted into the aerosol shell 810 together with the housing base 112 to complete the assembly, so as to form the detachable and reusable atomizing core 930. That is, the aerosol bomb 800 according to the present embodiment may be integrated into two parts, the first part being a part including the housing base 112 and the atomizing core 930, and the second part being a 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 reused, and the atomizing core 930 can be used for many times due to the fact that the first part is of a structure which can be detached and installed through simple insertion, and the using cost of consumers can be greatly saved.

< gas-liquid exchange element >

As shown in fig. 1b, the gas-liquid exchange element 290 is made of fibers bonded to form a three-dimensional network. Preferably by thermal bonding. The cross-section of the gas-liquid exchange element 290 may be of various geometric shapes, such as circular, oval, rectangular, etc. The gas-liquid exchange element 290 of the present invention has a density of 0.035 to 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 to 0.2 g/cm ³ . When the density is less than 0.035 g/cm ³ In time, the gas-liquid exchange element 290 is difficult to manufacture and has insufficient strength, and is easily deformed or wrinkled during assembly, affecting atomization stability or causing leakage. When the density is more than 0.3 g/cm ³ In the meantime, the gas-liquid exchange element 290 has insufficient ability to supply gas to the liquid storage element 100, and the negative pressure in the liquid storage element 100 is too high to cause the liquid to be difficult to be discharged.

In the present invention, the gas-liquid exchange element 290 has a capillary pressure of 2mm to 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 liable to leak. When the capillary pressure of the gas-liquid exchange element 290 is greater than 35mm, gas is difficult to permeate the gas-liquid exchange element 290 to enter the liquid storage element 100, so that the negative pressure in the liquid storage element 100 is too high, liquid in the liquid storage element 100 is difficult to be conducted to the atomizing core 930 through the gas-liquid exchange element 290, and the content of liquid on the atomizing core 930 is insufficient, thereby affecting the atomizing quality. The capillary pressure of the gas-liquid exchange element 290 is preferably 2.5mm to 25mm, more preferably 3mm to 10mm. The gas-liquid exchange element 290 may be selected to have an appropriate capillary pressure for different atomization requirements.

< fibers and bicomponent fibers >

The gas-liquid exchange element 290 is preferably made of bicomponent fibers 2 of sheath-core structure bonded together. The bicomponent fibers 2 of the sheath-core structure may be of a concentric or eccentric configuration. The bicomponent fibers 2 may be filaments or staple fibers. The gas-liquid exchange element 290 may be made by selecting suitable bicomponent fibers 2 according to the performance requirements of the gas-liquid exchange element 290. The core layer of the bicomponent fiber 2 has a melting point higher than that of the sheath layer by 20 ℃ or more, and the core layer can maintain a certain rigidity when the fibers are thermally bonded, so that the gas-liquid exchange element 290 with uniform gaps can be conveniently manufactured.

FIG. 1c is an enlarged cross-sectional schematic view of the bicomponent fiber of FIG. 1 b. As shown in fig. 1c, the skin layer 21 and the core layer 22 are of a concentric structure. FIG. 1d is another enlarged schematic cross-sectional view of the bicomponent fiber of FIG. 1 b. As shown in fig. 1d, the skin layer 21 and the core layer 22 are of an eccentric structure. Bicomponent fibers 2 are either filaments or staple fibers. The gas-liquid exchange element 290 may be formed by selecting suitable bicomponent fibers depending on the performance requirements of the gas-liquid exchange element 290.

The sheath 21 of the bicomponent fiber 2 may be polyolefin, copolyester of polyethylene terephthalate (abbreviated as Co-PET), polytrimethylene terephthalate (abbreviated as PTT), polybutylene terephthalate (abbreviated as PBT), polylactic acid, polyamide-6, or the like. Polyolefins are polymers of olefins, and are generally a generic name for thermoplastic resins obtained by polymerizing or copolymerizing an α -olefin such as ethylene, propylene, 1-butene, 1-pentene, 1-hexene, or the like, alone.

The bicomponent fiber 2 used to make the gas-liquid exchange element 290 of the present invention has a fineness of 1.5 to 30 denier, preferably 2 to 15 denier. Bicomponent fibers 2 having a sheath-core structure of between 2 and 15 denier are readily fabricated into the gas-liquid exchange element 290. For lower viscosities of the liquid being atomized, it is preferred to use smaller denier fibers, such as 1.5 denier, 2 denier, or 3 denier fibers, for the gas-liquid exchange element 290. For higher viscosity of the atomized liquid, it is preferable to use fibers having larger fineness for the gas-liquid exchange element 290, such as 6 denier, 10 denier, 15 denier, or 30 denier fibers.

In this embodiment, the gas-liquid exchange element 290 is preferably formed of two components with short dimension by thermal bonding to form a three-dimensional structure of a three-dimensional network, the skin layer 21 is polyethylene, and the core layer 22 is polypropylene or PET. The density of the gas-liquid exchange element 290 is between 0.035 and 0.3 g/cm ³ Preferably 0.05 to 0.2 g/cm ³ The gas-liquid exchange element 290 has good strength and good flexibility, and has a fast liquid transfer rate and the ability to replenish the liquid storage element 100 with gas. Such a gas-liquid exchange element 290 may be used for atomization of e-cigarette smoke liquid and CBD liquid medicine, and the like.

In this embodiment, the sheath 21 of the bicomponent fiber 2 can be replaced by polypropylene, co-PET, polyamide-6, PBT or PTT, and the gas-liquid exchange element 290 made of the same has higher temperature resistance.

< liquid storage element >

The liquid storage element 100 is a component for storing liquid in the aerosol bomb 800, and the liquid to be atomized is injected into the liquid storage element 100. The reservoir member 100 may be a cavity made of plastic or metal, and the cavity may be filled with a porous material for storing liquid. In use, liquid in the liquid storage element 100 is conducted to the atomizing core 930 through the gas-liquid exchange element 290 and atomized when needed.

The aerosol shell 810 may be provided with a liquid injection hole (not shown) communicating with the inside of the liquid storage element 100, and the liquid injection hole may be provided with a sealing plug (not shown). That is, a liquid injection hole may be provided in the cartridge case 810 of the cartridge 800 located at the reservoir 100. When liquid needs to be supplemented into the liquid storage element 100, the sealing plug is opened, liquid is injected, and the sealing plug is plugged into the liquid injection hole again. The aerosol bomb 800 adopts an open type liquid injection structure, so that the use cost of the aerosol bomb 800 can be further reduced.

< atomizing core >

The atomizing core 930 is the component of the aerosol bomb 800 that atomizes the liquid. The common atomizing core 930 that can be used in the present invention includes a glass fiber bundle atomizing core 930 wound with a heating wire, a cotton rope atomizing core 930 wound with a heating wire, a porous ceramic atomizing core 930 embedded with a heating wire, a compressed cotton atomizing core 930 embedded with a heating wire, or a spiral heating wire atomizing core 930 coated with a non-woven fabric, etc. The gas-liquid exchange element 290 of the present invention may be in direct contact with the atomizing core 930 and conduct liquid from the reservoir element 100 to the atomizing core 930. A relay liquid guide 939 may also be added between the atomizing core 930 and the gas-liquid exchange element 290. In the present invention, the relay liquid guiding element 939 is a liquid guiding element capable of conveying the liquid in the liquid storage element 100 to the atomizing core in the aerosol 800. Specifically, the liquid in the liquid storage element 100 is conducted to the relay liquid guiding element 939 through the gas-liquid exchanging element 290, and the relay liquid guiding element 939 conducts the liquid to the atomizing core 930 again. In the present embodiment, the gas-liquid exchange element 290 is in direct contact with the atomizing core 930, and a spiral heating wire atomizing core 930 coated with a cotton nonwoven fabric is preferably used.

In use, when 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, liquid on the atomizing core 930 is atomized, and aerosol generated by atomization escapes through the aerosol channel 1303 and the aerosol outlet 1301. When the liquid content on the atomizing core 930 is reduced during atomization, the gas-liquid exchange element 290 conducts the liquid from the liquid storage element 100 to the atomizing core 930. As the liquid in the reservoir 100 is directed out of the nebulizer, the negative pressure in the reservoir 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.

The atomizing core 930 also includes a wire 933, the wire 933 being connected to a wire lead 936 or a power supply (not shown).

Second embodiment

FIG. 2a is a schematic longitudinal cross-sectional view of a second embodiment of the disclosed aerosol bomb; FIG. 2b is a schematic cross-sectional view of the gas-liquid exchange element of FIG. 2 a; FIG. 2c is another schematic cross-sectional view of the gas-liquid exchange element of FIG. 2 a. The structure of this embodiment is similar to that of the first embodiment, and the same parts as the first embodiment are not described again in the description of this embodiment.

As shown in fig. 2a, the aerosol cartridge according to the second embodiment of the present invention includes a liquid storage element 100, an atomizing core 930, and a gas-liquid exchange element 290 communicating 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 supplemented to the liquid storage element 100 through the gas-liquid exchange element 290.

In this embodiment, an atomizing core 930 such as porous ceramic with embedded heating wire or compressed cotton with embedded heating wire is used. In addition, the aerosol bomb further comprises a relay liquid guide element 939, and the relay liquid guide element 939 may be a non-woven fabric covering the atomizing core 930. The intermediate liquid guiding member 939 may also be a tube made of bi-component fibers 2 bonded together, and the atomizing core 930 is inserted into the tube-shaped intermediate liquid guiding member 939 and is in close contact with the inner wall of the intermediate liquid guiding member 939.

The liquid storage element 100 is formed by a space surrounded by the aerosol shell 810, the wall of the aerosol passage 1303, and the gas-liquid exchange element 290. The reservoir member 100 may have a through bore 130 of the reservoir member 100 extending axially through the reservoir member 100. The through bore 130 of the reservoir member 100 may also serve as an aerosol passage 1303. One end of the aerosol passage 1303 passes through the gas-liquid exchange member 290 and mates with the inner bore of the gas-liquid exchange member 290 to prevent fluid leakage.

In this embodiment, the gas-liquid exchange element 290 is formed by thermally bonding the bicomponent fiber 2 having a sheath-core structure to form a three-dimensional network, the sheath 21 of the bicomponent fiber 2 is polyethylene, and the core 22 is polypropylene. The cross-section of the gas-liquid exchange element 290 is circular, and a gas-liquid exchange element through hole 2903 axially penetrating the gas-liquid exchange element is provided at the center. Gas-liquid exchange element 290 includes a high capillary 2901 near the center and a low capillary 2902 remote from the center but contiguous with high capillary 2901. The density of the low capillary 2902 is 0.035-0.15 g/cm ³ The high capillarity portion 2901 has a density of 0.15-0.3 g/cmRice and its production process ³ . The density of the high capillaries 2901 and low capillaries 2902 may also be similar, each in the range of 0.035-0.3 g/cm ³ In this range, however, the high capillary 2901 is made of a fiber having a small fineness, and the low capillary 2902 is made of a fiber having a large fineness. The capillary pressure of low-capillary 2902 is 2mm-35mm, preferably low-capillary 2902 has a capillary pressure of 2.5mm to 25mm, more preferably 3mm to 10mm. A low capillary 2902 of appropriate capillary pressure may be selected for different atomization requirements.

In this embodiment, when all of the high capillary 2901 and the low capillary 2902 are wetted with the liquid, both the high capillary 2901 and the low capillary 2902 can conduct the liquid, but only the low capillary 2902 can conduct the gas.

The high capillary 2901 and the low capillary 2902 may be integrally formed, or may be assembled after being separately formed.

Preferably, low-capillary portion 2902 includes a buffer space, where a portion of low-capillary portion 2902 is not wetted by liquid during normal use. In this case, the thickness of the gas-liquid exchange element 290 is preferably 1mm or more, most preferably 2mm or more, for example, 3mm, 4 mm and 5mm, and those skilled in the art can determine the thickness of the gas-liquid exchange element 290 according to the limitation of the space of the aerosol bomb 800, but the gas-liquid exchange element 290 should not be less than 1mm at the lowest in order to ensure the existence of the buffer space. In normal use, if high capillary 2901 is wetted with liquid, but low capillary 2902 is only partially wetted with liquid, and the buffer space is not wetted, high capillary 2901 can conduct liquid and low capillary 2902 can conduct gas, and in this case, the portion of low capillary 2902 that is not wetted with liquid has a buffer space, reducing the risk of liquid leaking from the aerosol bomb. In transportation or extreme environments, when the air pressure changes suddenly, the buffer space can temporarily store excessive liquid in the liquid storage element 100, so that the risk of liquid leakage from the aerial bomb 800 can be effectively avoided.

The outer peripheral wall of the gas-liquid exchange element 290 is tightly matched with the inner peripheral wall of the aerial fog shell, one side of the gas-liquid exchange element 290 is contacted with the liquid in the liquid storage element 100, and the other side of the gas-liquid exchange element 290 is contacted with the relay liquid guide element 939. When in use, the liquid in the liquid storage component 100 is conducted to the relay liquid guiding component 939 through the gas-liquid exchange component 290, and the relay liquid guiding component 939 conducts the liquid to the atomizing core 930. As the liquid in the liquid storage element 100 is guided out for atomization, the negative pressure in the liquid storage element 100 increases, and 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 is kept stable in the atomization process. The working principle of this embodiment is similar to that of the first embodiment.

In this embodiment, the aerosol bomb 800 further comprises a condensate absorbing element 400, and the condensate absorbing element 400 is installed in the aerosol channel 1303, so that the condensate generated by the aerosol can be absorbed, and the consumption experience is improved.

In this embodiment, the aerosol bomb 800 further includes a silica gel aerosol cap 1304. As shown in fig. 2a, the longitudinal section of the silicone aerosol pipe cap 1304 is an inverted T-shaped tubular structure having a through hole axially penetrating through the silicone aerosol pipe cap 1304.
