First embodiment
FIG. 1a is a schematic cross-sectional view of a gas-liquid exchange element according to a first embodiment of the present invention.
As shown in fig. 1a, the gas-liquid exchange element 290 according to the present invention includes a gas-liquid exchange element body 2900, a gas-liquid exchange element sleeve 2905 at least partially covering the gas-liquid exchange element body 2900, and a gas-liquid exchange element capillary hole 2904 disposed between an outer peripheral wall of the gas-liquid exchange element body 2900 and an inner peripheral wall of the gas-liquid exchange element sleeve 2905 and axially penetrating the gas-liquid exchange element 290, a lower end surface of the gas-liquid exchange element sleeve 2905 is close to a lower end surface of the gas-liquid exchange element body 2900 or flush with the lower end surface of the gas-liquid exchange element body 2900, and the gas-liquid exchange element body 2900 is made of fibers by bonding.
In the present invention, the lower end surface of the gas-liquid exchange element 290 refers to an end surface of the gas-liquid exchange element 290 that contacts the atomizing core liquid guide element 932. The lower end surface of the gas-liquid exchange element sleeve 2905 close to the lower end surface of the gas-liquid exchange element body 2900 means: the distance difference between the lower end surface of the gas-liquid exchange element sleeve 2905 and the lower end surface of the gas-liquid exchange element body 2900 in the axial direction of the gas-liquid exchange element body 2900 is not more than one fifth of the height of the gas-liquid exchange element body 2900.
In this embodiment, the lower end surface of the gas-liquid exchange element sleeve 2905 is preferably flush with the lower end surface of the gas-liquid exchange element body 2900.
The gas-liquid exchange element 290 is preferably a cylindrical body, such as a cylinder, an elliptical cylinder, a square cylinder, etc., having gas-liquid exchange element capillary holes 2904 extending axially therethrough. Preferably, the gas-liquid exchange element capillary openings 2904 are disposed parallel to the central axis of the column. The wick 2904 preferably forms a wick groove or protrusion on the outer perimeter wall of the wick body 2900 or on the inner perimeter wall of the wick sleeve 2905, which when assembled form the wick 2904. The cross-section of the capillary groove formed in the outer peripheral wall of the gas-liquid exchange element body 2900 may also be of various geometric shapes, such as a semicircular shape, a rectangular shape, a semi-elliptical shape, and the like.
In this embodiment, the gas-liquid exchange element 290 includes a gas-liquid exchange element body 2900 having a circular cross section, a gas-liquid exchange element sleeve 2905 covering the gas-liquid exchange element body 2900, and a gas-liquid exchange element capillary hole 2904 provided between an outer peripheral wall of the gas-liquid exchange element body 2900 and an inner peripheral wall of the gas-liquid exchange element sleeve 2905 and axially penetrating through the gas-liquid exchange element 290, the gas-liquid exchange element capillary hole 2904 is constituted by a space defined by a capillary groove formed on the outer peripheral wall of the gas-liquid exchange element body 2900 and the inner peripheral wall of the gas-liquid exchange element sleeve 2905, and the cross section of the capillary groove formed on the outer peripheral wall of the gas-liquid exchange element body 2900 is semicircular.
The space of the gas-liquid exchange element capillary bore 2904 is defined by the gas-liquid exchange element body 2900 and the gas-liquid exchange element sleeve 2905, and the maximum inscribed circle diameter of the minimum cross section of the gas-liquid exchange element capillary bore 2904 defined by the gas-liquid exchange element body 2900 and the gas-liquid exchange element sleeve 2905 is 0.05mm to 2.0mm, such as 0.05, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, and the like, preferably 0.2mm to 1.2 mm. The smaller cross-section of the element capillary 2904 is suitable for applications with less viscous liquid to be atomized, or with less atomization; the larger cross-section of the element capillary 2904 is suitable for applications where the viscosity of the liquid to be atomized is higher, or where the amount of atomization is greater. When the maximum inscribed circle diameter of the minimum cross section of the gas-liquid exchange element capillary 2904 is less than 0.05mm, the processing is difficult and the cost performance is too poor. When the maximum inscribed circle diameter of the minimum cross section of the gas-liquid exchange element capillary openings 2904 is greater than 2.0mm, the capillary openings are too large to ensure good gas-liquid exchange, and too large gas-liquid exchange element capillary openings 2904 can cause the gas-liquid exchange element 290 to be too large for use in small-sized aerosol projectiles.
The gas-liquid exchange element body 2900 is made of bonded fibers and has good liquid-conducting performance. The fibers may be filaments or staple fibers. The fibers making up the element 2900 may be monocomponent fibers or bicomponent fibers or a mixture of both. The element 2900 may be made of monocomponent fibers bonded with a binder or plasticizer, or may be made of bicomponent fibers in a sheath-core or side-by-side configuration. The gas/liquid exchange element body 2900 is preferably made of bicomponent fibers 2 with a sheath-core structure by thermal bonding, which is advantageous for obtaining a pure product and reducing the cost because no binder or plasticizer is required for thermal bonding. The fiber from which the element body 2900 is made has a denier of 1 to 30, preferably 2 to 10.
FIG. 1b is an enlarged schematic cross-sectional view of a bicomponent fiber according to the first embodiment of the utility model. As shown in fig. 1b, the skin layer 21 and the core layer 22 are of a concentric structure. FIG. 1c is an enlarged cross-sectional view of another bicomponent fiber according to the first embodiment of the utility model. As shown in fig. 1c, 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 body 2900 may be formed from suitable bicomponent fibers depending on the performance requirements of the gas liquid exchange element 290.
The melting point of the core layer 22 of the bicomponent fiber 2 with the sheath-core structure is higher than that of the sheath layer 21 by more than 20 ℃, so that the core layer 22 can keep better rigidity during thermal bonding, and the gas-liquid exchange element body 2900 is favorably molded. The sheath layer 21 of the bicomponent fiber 2 having a sheath-core structure may be a common polymer, such as polyethylene, polypropylene, polylactic acid, polybutylene succinate (PBS), low-melting copolyester (co-PET), polyethylene terephthalate (PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), a copolymer of butylene adipate and butylene terephthalate (PBAT), polyamide, or the like.
FIG. 1d is a schematic diagram of a first embodiment of an aerosol container having a gas-liquid exchange element in accordance with the present invention;
fig. 1e is another schematic structural diagram of the aerosol bomb with a gas-liquid exchange element according to the first embodiment of the utility model. As shown in fig. 1d and 1e, according to the first embodiment of the aerosol bomb 800 with the gas-liquid exchange element 290, the aerosol bomb 800 includes the gas-liquid exchange element 290.
The aerosol bomb 800 further comprises a liquid storage element 100 and an atomizing core 930, and the atomizing core 930 comprises an atomizing core liquid guiding element 932 and a heating element 931.
At least one gas-liquid exchange element 290 is connected with the liquid storage element 100 and the atomizing core liquid guiding element 932, and the liquid in the liquid storage element 100 is transmitted to the atomizing core liquid guiding element 932 through the gas-liquid exchange element 290.
The wick capillary 2904 of the at least one wick 290 communicates with the reservoir 100 and the wick wicking 932, and the end opening of the wick capillary 2904 communicating with the wick wicking 932 is blocked by the wick wicking 932 such that external air cannot directly enter the wick capillary 2904.
In the aerosol bomb 800 of the present invention, the liquid storage element 100 is a member for storing the liquid to be atomized. Different liquids may be stored therein depending on the purpose of the application, such as tobacco tar for e-cigarettes, etc. The cross-section of the reservoir member 100 can be a variety of shapes, such as circular, oval, rectangular, etc., or a combination of various geometric shapes. A liquid filling port may be provided in the liquid storage element 100, and the liquid filling port may be closed after the liquid is filled.
The aerosol cartridge 800 further comprises an aerosol cartridge housing 810, the reservoir element 100 being disposed in the aerosol cartridge housing 810. The reservoir component 100 can have a reservoir component through-hole 130 that extends axially through the reservoir component 100. The reservoir element through bore 130 can serve as an aerosol passage 1303 for the aerosol projectile 800.
The aerosol bomb 800 of the present invention further comprises an atomizing chamber 934, and the atomizing chamber 934 is a cavity in which the liquid is vaporized or atomized. In this embodiment, the aerosolization chamber 934 is disposed in the area between the bottom of the reservoir 100, the aerosol shell housing 810, and the housing base 112. The atomizing chamber 934 is provided with the atomizing core 930 therein, and an air inlet hole may be provided as required, for example, a base portion through hole 1122 is provided on the housing base 112 as an air inlet 1121. The liquid is atomized by the atomizing core 930 in the atomizing chamber 934 and exits the aerosol bomb 800 through the aerosol passage 1303 via the aerosol outlet 1301.
The atomizing core 930 of the present invention generally refers to a component that vaporizes or atomizes a liquid as required for use. The atomizing core 930 comprises an atomizing core liquid guiding element 932 and a heating element 931, and the atomizing core liquid guiding element 932 can be a capillary material such as cotton fiber or glass fiber.
The atomizing core 930 also includes a wire 933 and wire leads 936. The heating element 931 is connected to a power source (not shown) via a lead 933 and a lead pin 936.
The bottom of the atomizing chamber 934 may be provided with a support member 935, and the support member 935 may be made of a material such as silica gel to enhance the contact communication between the gas-liquid exchange element 290 and the atomizing core liquid guide element 932. And the atomization core liquid guide element 932 is beneficial to plugging the end opening of the capillary hole 2904 of the gas-liquid exchange element communicated with the atomization core liquid guide element, so that external air cannot directly enter the capillary hole 2904 of the gas-liquid exchange element.
In this embodiment, the bottom of the liquid storage component 100 is provided with a bottom partition 103 separated from the atomizing chamber 934, and the bottom partition 103 is provided with one or more partition through holes 9341 which are used for communicating the atomizing chamber 934 with the liquid storage component 100 and penetrate through the bottom partition 103. When the liquid atomization device is installed, liquid can be injected into the liquid storage element 100 from the partition through hole 9341, then the gas-liquid exchange element 290 is installed in the partition through hole 9341, and then the atomization core 930, the support part 935, the housing base 112 and the like are installed. The gas-liquid exchange element 290 may be located mostly in the nebulizing chamber 934, as shown in FIG. 1 d; the gas-liquid exchange element 290 may also be located mostly within the reservoir element 100, as shown in FIG. 1 e. As shown in fig. 1d, in the present embodiment, two gas-liquid exchange elements 290 may be used, which are respectively connected to two ends of the atomizing core liquid guiding element 932; as shown in fig. 1e, a gas-liquid exchange element 290 and a common liquid guiding element 200 made of bonded fibers can be used to connect with two ends of the atomizing core liquid guiding element 932, respectively, and the common liquid guiding element 200 does not include the gas-liquid exchange element capillary 2904, so that the manufacturing is convenient and the cost is low.
In a modified embodiment, the inner peripheral wall of the partition through hole 9341 may also serve as the gas-liquid exchange element sleeve 2905, and in this case, the gas-liquid exchange element body 2900 is simply inserted into the partition through hole 9341 so that the lower end surface of the partition through hole 9341 is close to the lower end surface of the gas-liquid exchange element body 2900, and there is no need to separately provide a separately molded gas-liquid exchange element sleeve.
After the aerosol bomb 800 is assembled, due to the capillary action of the gas-liquid exchange element body 2900 and the atomizing core liquid guiding element 932, the liquid in the liquid storage element 100 is conducted to the atomizing core liquid guiding element 932 through the gas-liquid exchange element 290, and as the liquid in the liquid storage element 100 is guided out, a negative pressure difference is formed between the inside of the liquid storage element 100 and the outside. When the negative pressure difference between the inside of the liquid storage element 100 and the outside is high enough, the outside air can enter the liquid storage element 100 through the capillary pore 2904 of the gas-liquid exchange element 290, but the external air cannot directly enter the capillary pore 2904 of the gas-liquid exchange element 290 because the atomizing wick liquid guide element 932 seals the end opening of the capillary pore 2904 of the gas-liquid exchange element 290 communicated with the atomizing wick liquid guide element 932, and the outside air must pass through the atomizing wick liquid guide element 932 to enter the capillary pore 2904 of the gas-liquid exchange element 290 and finally enter the liquid storage element 100. The capillary force of the wicking element 932 decreases as the liquid content therein increases until a negative pressure differential with the reservoir element 100 reaches equilibrium with the ambient. The wick element 932 is unsaturated at equilibrium, thus providing further liquid absorption capability and reducing the risk of oil blow-up due to excessive liquid content in the wick element 932 during atomization.
When the liquid in the atomizing core liquid guiding element 932 is consumed by atomization, the capillary force of the atomizing core liquid guiding element 932 is increased, and the atomizing core liquid guiding element 932 performs gas-liquid exchange with the liquid storage element 100 through the gas-liquid exchange element 290 until the equilibrium state is reached again.
When the ambient temperature rises or the ambient air pressure decreases, the air in the liquid storage element 100 expands, the liquid in the liquid storage element 100 is led out, and the unsaturated atomization core liquid guide element 932 can absorb the liquid from the liquid storage element 100 through the gas-liquid exchange element 290, so that the risk of liquid leakage of the aerosol bomb 800 due to the rise of the ambient temperature or the reduction of the ambient pressure is reduced. If the ambient temperature or the external air pressure returns to the original state, the atomizing core liquid guiding element 932 seals the end opening of the capillary 2904 of the gas-liquid exchange element 290 communicated with the atomizing core liquid guiding element 932, so that the external air cannot directly enter the capillary 2904 of the gas-liquid exchange element, and partial liquid in the atomizing core liquid guiding element 932 enters the liquid storage element 100 through the gas-liquid exchange element 290 in preference to the external air. This is beneficial to the liquid to flow back and forth between the liquid storage element 100 and the atomizing core liquid guiding element 932 when the ambient temperature or pressure changes, thereby reducing the risk of liquid leakage of the aerosol bomb 800 during daily use. To reduce the risk of liquid leakage during long-term storage and transportation of the aerosol bomb, the aerosol outlet 1301 and the air inlet 1121 of the aerosol bomb may be sealed, for example, by installing a silicone plug.

The gas-liquid exchange element body 2900 is made of bonded fibers and has good liquid-conducting performance. The fibers may be filaments or staple fibers.

In this embodiment, the gas-liquid exchange element sleeve 2905 covers only a portion of the gas-liquid exchange element body 2900 from the bottom partition 103 to the lower end surface of the gas-liquid exchange element body 2900.
After the installation is finished, due to the capillary action of the gas-liquid exchange element 290, the relay liquid guiding element 939 and the atomizing core liquid guiding element 932, the liquid in the liquid storage element 100 is conducted to the atomizing core liquid guiding element 932 through the gas-liquid exchange element 290 and the relay liquid guiding element 939, and a negative pressure difference is formed between the inside of the liquid storage element 100 and the outside along with the conduction of the liquid in the liquid storage element 100. When the negative pressure difference between the inside of the liquid storage element 100 and the outside is high enough, the outside air can enter the liquid storage element 100 through the capillary pore 2904 of the gas-liquid exchange element 290, but because the relay liquid guiding element 939 blocks the end opening of the capillary pore 2904 of the gas-liquid exchange element 290 communicated with the relay liquid guiding element 939, the outside air must pass through the relay liquid guiding element 939 to enter the capillary pore 2904 of the gas-liquid exchange element 290 and finally enter the liquid storage element 100. The capillary force of the wicking element 932 decreases as the liquid content therein increases until a negative pressure differential with the reservoir element 100 reaches equilibrium with the ambient. The wick element 932 is unsaturated at equilibrium, thus providing further liquid absorption capability and reducing the risk of oil blow-up due to excessive liquid content in the wick element 932 during atomization.
When the liquid in the atomizing core liquid guiding element 932 is consumed by atomization, the capillary force of the atomizing core liquid guiding element 932 is increased, and the atomizing core liquid guiding element 932 exchanges gas and liquid with the liquid storage element 100 through the relay liquid guiding element 939 and the gas and liquid exchange element 290 until the equilibrium state is reached again.
When the ambient temperature rises or the ambient air pressure decreases, the air in the liquid storage element 100 expands, the liquid in the liquid storage element 100 is led out, and the unsaturated atomizing core liquid guiding element 932 can absorb the liquid from the liquid storage element 100 through the relay liquid guiding element 939 and the air-liquid exchange element 290, so that the risk of liquid leakage of the aerosol bomb 800 due to the rise of the ambient temperature or the reduction of the ambient pressure is reduced. If the ambient temperature or the external air pressure returns to the original state, because the relay liquid guiding element 939 blocks the end opening of the capillary pore 2904 of the gas-liquid exchange element 290 communicated with the relay liquid guiding element 939, part of the liquid in the relay liquid guiding element 939 and the atomizing core liquid guiding element 932 enters the liquid storage element 100 through the gas-liquid exchange element 290 in preference to the external air. This is beneficial to the liquid to and from between the liquid storage element 100 and the relay liquid guiding element 939 and the atomizing core liquid guiding element 932 when the ambient temperature or pressure changes, thereby reducing the risk of liquid leakage of the aerosol bomb 800 during the daily use.
FIG. 2c is another schematic cross-sectional view of a gas-liquid exchange element according to a second embodiment of the present invention. As shown in fig. 2c, the element capillary openings 2904 are defined by a plurality of axial channels separated by a ring between the element body 2900 and the element sleeve 2905. The gas-liquid exchange element capillary 2904 formed in this manner is more convenient to machine and assemble.
In summary, the gas-liquid exchange element 290 of the present invention has a simple structure and is suitable for use in a small-sized aerosol bomb 800 or an atomizing device. The aerosol bomb 800 using the gas-liquid exchange element 290 is suitable for applications such as electronic cigarettes, and may be used for quantitative atomization of inhalation-type liquid medicine in the medical field. The aerosol bomb 800 using the gas-liquid exchange element 290 has a compact structure and good leakage prevention, and can uniformly control the liquid release. If an airflow sensor is arranged in the external control device, the atomization of the liquid can be controlled according to the airflow, and the use is more convenient.
