First embodiment

FIG. 1a is a schematic longitudinal cross-section 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; FIG. 1c is an enlarged cross-sectional schematic view of the bicomponent fiber of FIG. 1 b; FIG. 1d is another enlarged cross-sectional schematic view of the bicomponent fiber of FIG. 1 b.

As shown in fig. 1a, according to the aerosol cartridge 800 of the first embodiment of the present invention, the aerosol cartridge 800 does not have an atomizing core, and the aerosol cartridge 800 includes a liquid storage element 100, an air-liquid exchange element 290 blocking the bottom opening of the liquid storage element 100, and an aerosol channel 1303 axially penetrating the liquid storage element 100.

In the present invention, the atomizing core is a component that heats and atomizes the liquid in the liquid storage element 100.

The aerosol bomb 800 is a three-dimensional structure designed by those skilled in the art, such as a cylinder, a square column, an elliptical cylinder, etc. The aerosol cartridge 800 includes an aerosol cartridge housing 810, a reservoir element 100 contained within the aerosol cartridge housing 810, and an aerosol channel 1303 extending axially through the reservoir element 100. The bottom of the liquid storage element 100 is provided with an opening, and the gas-liquid exchange element 290 seals the bottom opening of the liquid storage element 100.

In this embodiment, aerosol channel 1303 is formed by a tubular structure extending from the top of aerosol cartridge housing 810 into aerosol cartridge housing 810, and the length of aerosol channel 1303 is less than the length of aerosol cartridge housing 810. The opening between the end of aerosol passage 1303 remote from the top of aerosol cartridge housing 810 and aerosol cartridge housing 810 is the opening at the bottom of reservoir component 100. The gas-liquid exchange element 290 seals off the bottom opening of the liquid storage element 100. Thus, the reservoir 100 is formed by the space enclosed by the aerosol shell 810, the tube wall of the aerosol channel 1303 and the gas-liquid exchange element 290. A space surrounded by the gas mist bullet case 810 and the gas liquid exchanging element 290 forms a bottom storage chamber 820 below the gas liquid exchanging element 290.

The reservoir 100 may also be separately formed and assembled into the aerosol housing 810, in which case the reservoir 100 may have a reservoir through-hole 130 extending axially through the reservoir 100, and the reservoir through-hole 130 may also serve as the aerosol channel 1303.

The gas-liquid exchange element 290 has a gas-liquid exchange element through hole 2903 axially penetrating the gas-liquid exchange element 290, and the gas mist passage 1303 passes through the gas-liquid exchange element through hole 2903 to be tightly fitted with the gas-liquid exchange element 290 to prevent liquid leakage. A hollow plastic baffle (not shown) may be installed at the bottom opening of the liquid storage element 100, the shape of the plastic baffle is similar to the gas-liquid exchange element 290 but the size of the plastic baffle is slightly smaller than that of the gas-liquid exchange element 290, and the plastic baffle plays a role in positioning and supporting the gas-liquid exchange element 290 without affecting the liquid and gas guiding functions of the gas-liquid exchange element 290.

The outer peripheral wall of the gas liquid exchange member 290 is tightly fitted to the inner peripheral wall of the aerosol shell 810, and the gas liquid exchange member 290 side is in contact with the liquid in the liquid storage member 100. In use of the aerosol 800, the aerosol 800 is mounted on a host (not shown) having an atomizing core inserted into the bottom receiving chamber 820 of the aerosol 800, and the other side of the gas-liquid exchange element 290 contacts the atomizing core, thereby conducting the liquid in the liquid storage element 100 to the atomizing core.

< gas-liquid exchange element >

As shown in fig. 1b, the gas-liquid exchange element 290 is made of a three-dimensional network of fibers bonded together, 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 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 capability of introducing gas into the liquid storage element 100, and the negative pressure in the liquid storage element 100 becomes too high to make it difficult to discharge liquid.

In the present invention, the gas-liquid exchange element 290 has a capillary pressure of 1mm to 35mm, for example, 1mm, 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 1mm, 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, the gas is difficult to permeate the gas-liquid exchange element 290 to be supplemented to the liquid storage element 100, so that the negative pressure in the liquid storage element 100 is too high, the liquid in the liquid storage element 100 is difficult to be conducted to the atomizing core through the gas-liquid exchange element 290, and the content of the liquid on the atomizing core is insufficient, so that the atomizing quality is affected. Preferably, the gas-liquid exchange element 290 has a capillary pressure of 2mm to 25mm, more preferably 3mm to 10mm. The capillary pressure of the gas-liquid exchange element 290 may be selected to suit different atomization requirements. In order to provide sufficient strength to the gas-liquid exchange element, the thickness of the gas-liquid exchange element is greater than or equal to 1mm, such as 1mm, 2mm, 3mm, 5mm, 7mm, 10mm, etc. Because the inner space of the aerosol bomb is limited, the thickness of the gas-liquid exchange element is limited by the inner space of the aerosol bomb.

< fibers and bicomponent fibers >

The gas-liquid exchange element 290 is made of bonded fibers, and the gas-liquid exchange element 290 can be made of single component fibers such as polyamide 6, polyamide 66, polyamide 610, PET, PBT, PTT, etc. bonded by thermal bonding, adhesive or plasticizer, or the gas-liquid exchange element 290 can be made of bicomponent fibers 2 having a sheath-core structure. The bicomponent fibers 2 of the sheath-core structure may be of a concentric structure or an eccentric structure. 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 more than 20 ℃, so that the core layer can keep certain rigidity when thermal bonding is carried out between fibers, and 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 cross-sectional schematic 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. The bicomponent fibers 2 are filaments or staple fibers. The gas-liquid exchange element 290 may be made of 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 (Co-PET for short), polytrimethylene terephthalate (PTT for short), polybutylene terephthalate (PBT for short), polylactic acid, or polyamide-6. 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. When the viscosity of the atomized liquid is low, it is preferable to use fibers having a small fineness for the gas-liquid exchange element 290, such as fibers having a fineness of 1.5 denier, 2 denier or 3 denier. For higher viscosity liquids to be atomized, larger denier fibers, such as 6, 10, 15, 30 denier fibers, are preferred for the gas-liquid exchange element 290.

In this embodiment, the gas-liquid exchange element 290 is preferably formed of two components with short fibers thermally bonded to form a three-dimensional network. The skin layer 21 is polyethylene, the core layer 22 is polypropylene or PET, and the density of the gas-liquid exchange element 290 is 0.035-0.3 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. This gas-liquid exchangeThe switch 290 may be used for atomization of e-cigarette smoke fluid and CBD fluid, etc.

In this embodiment, the sheath 21 of the bicomponent fiber 2 can be replaced by polypropylene, co-PET, polyamide-6, PBT or PTT, etc., and the gas-liquid exchange element 290 made of the bicomponent fiber 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 a porous material for storing liquid may be filled in the cavity. When in use, the liquid in the liquid storage element 100 is conducted to the atomizing core through the gas-liquid exchange element 290 and is 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 where the cartridge 800 is located in the liquid storage element 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.

When the atomizer is used, the host with the atomizing core is inserted into the bottom accommodating chamber 820, the atomizing core is contacted with the gas-liquid exchange element 290, liquid on the atomizing core is atomized, the content of the liquid on the atomizing core is reduced, and the gas-liquid exchange element 290 conducts the liquid from the liquid storage element 100 to the atomizing core. 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 and the outside reaches a certain range, the outside air passes through the gas-liquid exchange element 290 and enters the liquid storage element 100.

Second embodiment

Fig. 2 is a schematic longitudinal sectional view of a second embodiment of the disclosed aerosol bomb. The structure of this embodiment is similar to that of the first embodiment, and the same parts as those of the first embodiment are not described again in the description of this embodiment.

As shown in fig. 2, according to the aerosol bomb 800 of the first embodiment of the present invention, the aerosol bomb 800 does not have an atomizing core, and the aerosol bomb 800 includes a liquid storage element 100, an air-liquid exchange element 290 blocking the bottom opening of the liquid storage element 100, and an aerosol channel 1303 axially penetrating the liquid storage element 100.

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 condensate generated by the aerosol can be absorbed, and the consumption experience can be improved.

The aerosol bomb of this embodiment also includes a silica gel aerosol cap 1304. As shown in fig. 2, the longitudinal section of the silicone aerosol pipe cap 1304 has an inverted T-shaped tubular structure with a through hole axially penetrating through the silicone aerosol pipe cap 1304. The silicone aerosol cap 1304 is inserted into the aerosol channel 1303 from the aerosol inlet end of the aerosol channel 1303, the outer peripheral wall of the insertion portion thereof abuts against the inner peripheral wall of the aerosol channel 1303, and the non-insertion end thereof abuts against the end of the aerosol channel 1303. The non-inserted end of the silicone aerosol cap 1304 has an outer diameter that is greater than the outer diameter of the aerosol channel 1303, thereby supporting and positioning the gas-liquid exchange element 290 with the non-inserted end of the silicone aerosol cap 1304. Silica gel is high temperature resistant, can use under normal atomizing temperature stably, therefore the use of silica gel aerial fog pipe cap 1304 can reduce the temperature resistance requirement to aerial fog passageway 1303 wall, can enlarge the material selection range of making aerial fog bullet shell and aerial fog passageway 1303 pipe wall.

The silicone aerosol cap 1304 may also prevent the condensate absorbing element 400 from falling out of the aerosol channel 1303. In addition, a filtering component can be assembled at the aerosol inlet of the silica gel aerosol pipe cap 1304, and the filtering component can be a filtering net or a filtering baffle plate with holes or a baffle plate (not shown), or a baffle plate arranged at the aerosol inlet, and is used for preventing large atomized liquid drops from directly rushing up to enter the aerosol channel 1303. When the flow baffle plate is adopted, atomized aerosol needs to bypass the flow baffle plate and then enters the aerosol channel 1303, and large-particle atomized liquid drops can be effectively prevented from directly rushing up to enter the aerosol channel 1303.

Third embodiment

Fig. 3 is a schematic longitudinal sectional view of a third embodiment of the disclosed aerosol bomb. 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. 3, according to the aerosol bomb 800 of the third embodiment of the present invention, the aerosol bomb 800 does not have an atomizing core, and the aerosol bomb 800 includes a liquid storage element 100, an air-liquid exchange element 290 blocking the bottom opening of the liquid storage element 100, and an aerosol channel 1303 axially penetrating the liquid storage element 100.

In this embodiment, a top seal 821 and a bottom seal 822 may be provided on the aerosol cartridge 800. Top seal 821 is used to seal the top of aerosol cartridge housing 810 and bottom seal 822 is used to seal the bottom of aerosol cartridge housing 810. Such as a top seal 821 or a bottom seal 822 made of silicone, as shown in fig. 1 c. Alternatively, the top seal 821 may be made of silicone rubber on the top and the bottom of the bullet 800 may be sealed with a paper-plastic composite film or a paper-aluminum-plastic composite film. Top seal 821 and bottom seal 822 may, on the one hand, prevent contamination of aerosol bomb 800 during storage and transportation, and on the other hand, reduce or prevent leakage of aerosol bomb 800 during storage and transportation.

Fourth embodiment

FIG. 4a is a schematic longitudinal cross-sectional view of a fourth disclosed embodiment of an aerosol can; FIG. 4b is a schematic cross-sectional view of the gas-liquid exchange element of FIG. 4 a; FIG. 4c is another schematic cross-sectional view of the gas-liquid exchange element of FIG. 4 a. The structure of this embodiment is similar to that of the first embodiment, and the same parts as those of the first embodiment are not described again in the description of this embodiment.

As shown in fig. 4a, in an aerosol bomb 800 according to a fourth embodiment of the present invention, the aerosol bomb 800 does not have an atomizing core, and the aerosol bomb 800 includes a liquid storage element 100, an air-liquid exchange element 290 for closing off the bottom opening of the liquid storage element 100, and an aerosol channel 1303 axially penetrating the liquid storage element 100.

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 is provided at the center. The gas-liquid exchange element 290 includes a high capillary portion 29 near the center01 and a low capillary 2902 remote from the center but adjacent to the high capillary. 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/cm ³ . The density of the high-wool part and the low-wool part can be similar and are respectively 0.035-0.3 g/cm ³ However, the high capillary 2901 is made of a small fiber and the low capillary 2902 is made of a large fiber. The capillary pressure of the low capillary 2902 is 1mm to 35mm, preferably the capillary pressure of the low capillary 2902 is 2mm to 25mm, more preferably 3mm to 10mm. The capillary pressure of low capillary 2902 may be selected as appropriate for different aerosolization requirements.

In the present embodiment, when both the high capillary portion 2901 and the low capillary portion 2902 are wetted with liquid, both the high capillary portion 2901 and the low capillary portion 2902 can conduct liquid, but only the low capillary portion 2902 can conduct 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 2mm or more, for example, 2mm, 3mm, 4 mm, 5mm, 7mm, 10mm, etc., 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 cannot be less than 2mm 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, in which 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 member 290 is tightly fitted to the inner peripheral wall of the aerosol shell 810, and one side of the gas-liquid exchange member 290 is in contact with the liquid in the liquid storage member 100. In use, the aerosol 800 is mounted to a host with an atomizing core inserted into the bottom receiving chamber 820 of the aerosol 800, and the other side of the gas-liquid exchange element 290 contacts the atomizing core, thereby conducting the liquid in the liquid storage element 100 to the atomizing core.

As shown in fig. 4b, the cross section of the gas-liquid exchange element 290 in this embodiment may be circular, the gas-liquid exchange element 290 has a gas-liquid exchange element through hole 2903 axially penetrating the gas-liquid exchange element 290, and the low capillary 2902 covers the high capillary 2901.

The cross section of the gas-liquid exchange element 290 in this embodiment may also be the structure shown in fig. 4c, that is, the cross section of the high capillary 2901 is rectangular, and the cross section of the low capillary 2902 is two hemispheres or two arched structures, so as to meet the requirement of diversified design of the aerosol bomb 800.

Fifth embodiment

Fig. 5 is a schematic longitudinal sectional view of a fifth embodiment of the disclosed aerosol bomb. The structure of this embodiment is similar to that of the first embodiment, and the same parts as those of the first embodiment are not described again in the description of this embodiment.

As shown in fig. 5, according to the aerosol cartridge 800 of the fifth embodiment of the present invention, the aerosol cartridge 800 does not have an atomizing core, and the aerosol cartridge 800 includes a liquid storage element 100, an air-liquid exchange element 290 blocking the bottom opening of the liquid storage element 100, and an aerosol channel 1303 axially penetrating the liquid storage element 100.

This embodiment is suitable for a large capacity aerosol bomb 800. Because the aerosol shell 810 has a large size, an aerosol shell partition 811 with a hollow central portion can be fitted in the bottom opening of the liquid storage element 100, the outer peripheral wall of the aerosol shell partition 811 is tightly fitted with the inner peripheral wall of the aerosol shell 810, and the gas-liquid exchange element 290 is mounted in the hollow central portion of the aerosol shell partition 811.

Seventh embodiment

Fig. 7 is a schematic longitudinal sectional view of an aerosol bomb according to a seventh embodiment of the present disclosure. The structure of this embodiment is similar to that of the first embodiment, and the same parts as those of the first embodiment are not described again in the description of this embodiment.

As shown in fig. 7, according to the aerosol bomb 800 of the seventh embodiment of the present invention, the aerosol bomb 800 does not have an atomizing core, and the aerosol bomb 800 includes a liquid storage element 100, an air-liquid exchange element 290 for closing off the bottom opening of the liquid storage element 100, and an aerosol channel 1303 axially penetrating the liquid storage element 100.

The lower portion of the gas-liquid exchange element 290 extends out of the bottom opening of the reservoir element 100. Since the lower portion of the gas-liquid exchange element 290 extends out of the bottom opening of the liquid storage element 100, the height of the gas-liquid exchange element 290 can be increased, and thus the capacity of the buffer space of the low capillary 2902 can be further increased, whereby the leakage prevention function of the aerosol bomb 800 can be further enhanced.

The lower portion of the gas-liquid exchange element 290 preferably exceeds the lower end of the aerosol passage 1303 by more than a quarter of the height of the gas-liquid exchange element 290, and more preferably by more than a half of the height of the gas-liquid exchange element 290. In this case, the outer peripheral wall of the gas-liquid exchange member 290 is fitted closely to the inner peripheral wall of the aerosol shell case 810, and the gas-liquid exchange member 290 side is in contact with the liquid in the liquid storage member 100. When in use, the aerosol bomb 800 is mounted to a host with an atomizing core, and after the atomizing core is inserted into the bottom accommodating chamber 820 of the aerosol bomb 800, the atomizing core can be contacted with the inner peripheral wall of the gas-liquid exchange element 290, so that the liquid in the liquid storage element 100 is conducted to the atomizing core. In this way, the structure of the aerosol bomb 800 can be more compact and the assembly can be more convenient.

In conclusion, the aerosol bomb does not comprise the atomizing core, the aerosol bomb is replaced after liquid is used up, and the atomizing core can be reused, so that the cost is greatly reduced, and the resource waste is reduced. When the atomizing device is used, the aerosol bomb and the atomizing core are installed on the host machine, the gas-liquid exchange element can stably conduct liquid to the atomizing core, and gas is introduced into the liquid storage element when necessary, so that stable pressure is maintained in the liquid storage element, and stable atomization is ensured.
