Description

Aerosol bullet, aerosol bullet with liquid injection port and aerosol dispersing device

Technical Field

The utility model relates to an aerosol bullet, an aerosol bullet with a liquid injection port and an aerosol dispersing device, in particular to an aerosol bullet with an independent air guide element, an aerosol bullet with a liquid injection port and an aerosol dispersing device which are used in the application fields of electronic cigarettes, medicine solution atomization and the like.

Background

Atomization technology is widely used in the fields of electronic cigarettes and the like. A common technique in electronic cigarettes is to heat an atomizing wick liquid guide element in direct communication with the tobacco tar to atomize the liquid.

For example, in a conventional aerosol-based design, where a heating element heats a glass or cotton fiber bundle passing through an atomizing chamber cavity, liquid is directed out of an aerosol passageway after atomizing in the atomizing chamber cavity, the aerosol-based design requires that the atomizing chamber cavity be "properly" mated with an atomizing wick liquid guide element, allowing liquid to conduct from the atomizing wick liquid guide element while allowing outside air to enter the liquid storage element from a void within the atomizing wick liquid guide element or a gap between the atomizing wick liquid guide element and the atomizing chamber cavity, thereby avoiding a continuous rise in negative pressure in the liquid storage element after liquid consumption. Because liquid guide elements such as glass fiber bundles, cotton fiber bundles, non-woven fabrics and the like are soft and lack of fixed shapes, gaps inside the liquid guide element of the atomization core and between the liquid guide element of the atomization core and the cavity of the atomization chamber are difficult to precisely control, and air in the small gap is difficult to enter the liquid storage element, so that the atomization core is lack of liquid and is burnt; when the gap is too large, liquid is accumulated on the atomization core, oil is exploded during atomization, and when the gap is too large, liquid can leak from the atomization core, be inhaled into a mouth of a consumer or leak from an aerosol bullet, and all influence the stability of atomization and consumption experience. In addition, in the prior art, atomized liquid cannot return to the liquid storage element after leaking from the gap, so that the atomized liquid is wasted.

In another conventional aerosol bomb design, the atomized liquid is stored in a liquid storage element made of bonded fibers, the liquid in the liquid storage element is transmitted to the atomized core liquid guide element through a liquid guide through hole in the atomized core shell, and a heating element heats the liquid on the atomized core liquid guide element, and the liquid escapes from the aerosol channel after being atomized in the atomizing chamber. In order to make the external air supplement enter the liquid storage element so as to make the atomization smoothly proceed, the liquid guide through hole of the atomization core shell is not completely blocked by the atomization core liquid guide element, or an independent through hole which is not blocked by the atomization core liquid guide element is arranged on the atomization core shell. Because the atomized liquid is pulled by the capillary force of the bonding fiber, the aerosol bullet is not easy to leak liquid, but along with the release of the liquid in the bonding fiber, the capability of the bonding fiber for releasing the liquid is continuously attenuated, so that the atomization amount and the taste are reduced, and the consumption experience is influenced.

First embodiment

FIG. 1 is a schematic view of an aerosol bomb according to a first embodiment of the present utility model; FIG. 2 is a first exploded view of the aerosol cartridge of FIG. 1; FIG. 3 is a second exploded view of the aerosol cartridge of FIG. 1; fig. 4 is a schematic cross-sectional view of the atomizing core shown in fig. 1.

As shown in fig. 1 to 4, an aerosol bomb 800 according to a first embodiment of the present utility model includes an atomizing core 930, a liquid storage member 100 for supplying liquid to the atomizing core 930, and a separate air guide member 600 for communicating the liquid storage member 100 with the external atmosphere; the atomizing core 930 includes a tubular atomizing core housing 9324, a tubular atomizing core liquid guiding element 932 closely adhered to an inner peripheral wall of the atomizing core housing 9324, an atomizing core liquid guiding element through-hole 932b axially penetrating the atomizing core liquid guiding element 932, and a heating element 931 adhered to the inner peripheral wall of the atomizing core liquid guiding element 932; the atomization core housing 9324 is provided with a housing liquid guide through hole 9325, and the atomization core liquid guide element 932 seals the housing liquid guide through hole 9325 and contacts with the atomized liquid in the liquid storage element 100 through the housing liquid guide through hole 9325; the minimum height OL1 of the close-fitting part of the atomizing core outer shell 9324 and the liquid guiding element 932 above the outer shell liquid guiding through hole 9325 is larger than 0.8mm, and the minimum height OL2 of the close-fitting part of the atomizing core outer shell 9324 and the liquid guiding element 932 below the outer shell liquid guiding through hole 9325 is larger than 0.8mm; the aerosol cartridge 800 further comprises an aerosol cartridge housing 810 and a second housing base 824 disposed at the bottommost portion of the aerosol cartridge housing 810, a first housing base 823 disposed inside the aerosol cartridge housing 810 and spaced from the second housing base 824, and a buffer chamber 828 disposed between the first housing base 823 and the second housing base 824, wherein the independent air guide element 600 communicates with the liquid storage element 100 and the buffer chamber 828.

The tight adherence of the nebulizing core liquid guiding element 932 in the inner peripheral wall of the nebulizing core housing 9324 is of special significance in the present utility model, meaning that after the reservoir element 100 is filled with the nebulized liquid, outside air cannot enter the reservoir element 100 through the nebulizing core 930 during normal use of the product.

When the aerosol cartridge 800 is used, the atomized liquid in the aerosol cartridge 800 is atomized and consumed, and the external air can only enter the liquid storage element 100 through the independent air guide element 600. Since the atomizing core 930 according to the present utility model cannot supplement the gas into the liquid storage member 100 under normal use, if the separate gas guide member 600 is removed, the atomizing core 930 according to the present utility model cannot atomize the liquid normally in the aerosol dispensing device 1 described later.

The minimum height OL1 of the closely-adhered portion of the atomizing core housing 9324 and the liquid-guiding element 932 above the housing liquid-guiding through-hole 9325 is greater than 0.8mm, preferably greater than 1.2mm, 1.5mm, or 1.8mm; the minimum height OL2 of the portion of the atomizing core housing 9324 under the housing liquid-conducting through-hole 9325 in close contact with the liquid-conducting element 932 is greater than 0.8mm, preferably greater than 1.2mm, 1.5mm, or 1.8mm.

When the atomized liquid is just injected into the aerosol, as long as the minimum height of the tightly adhered part of the atomizing core housing 9324 and the liquid guiding element 932 above and below the housing liquid guiding through hole 9325 is greater than 0.5mm, external air can be prevented from entering the liquid storage element 100 through the tightly adhered parts of the upper and lower edges of the atomizing core liquid guiding element 932 and the atomizing core housing 9324. However, as the liquid guiding cloth is soaked by the atomized liquid and then gradually swells and deforms, the swelling and deformation at the upper and lower ends of the liquid guiding cloth are often more serious, and the compactness of the two ends of the liquid guiding element 932 of the atomization core and the inner wall of the outer casing 9324 of the atomization core is damaged, which may cause the air leakage and the liquid leakage of the atomization core 930, and even the whole atomization function is invalid, so the minimum height of the tightly-adhered part of the outer casing 9324 of the outer casing and the liquid guiding element 932 above and below the liquid guiding through hole 9325 of the outer casing is greater than 0.8mm, and the external air can be effectively prevented from entering the liquid storage element 100 through the tightly-adhered parts of the upper and lower edges of the liquid guiding element 932 of the atomization core and the outer casing 9324 of the atomization core.

< liquid storage element >

In the aerosol cartridge 800 of the present utility model, the liquid storage element 100 is a member for storing an atomized liquid. Different liquids may be stored therein, such as e-cigarette tar, CBD solutions, pharmaceutical solutions, etc., depending on the purpose of the application.

As shown in fig. 1 to 3, the liquid storage element 100 has a liquid storage element through hole 130 penetrating the liquid storage element 100 axially. The liquid storage element through-hole 130 may serve as the aerosol passage 1303 of the aerosol cartridge 800. One end of the aerosol passage 1303 is an atomization module connection port 1302 communicated with an atomization core 930, and the other end is an aerosol outlet 1301. The aerosol passage 1303 may be integrally formed with the liquid storage element 100, and the liquid storage element through hole 130 may be used as the aerosol passage 1303, or may be made of plastic, metal, or the like, and then assembled into the aerosol cartridge 800.

In the present utility model, the aerosol cartridge 800 includes an aerosol cartridge housing 810 and a second housing base 824 provided at the bottommost portion of the aerosol cartridge housing 810, a first housing base 823 provided inside the aerosol cartridge housing 810 at a distance from the second housing base 824, and a buffer chamber 828 provided between the first housing base 823 and the second housing base 824, and the independent air guide member 600 communicates the liquid storage member 100 and the buffer chamber 828.

Specifically, in the present utility model, as shown in fig. 1 to 3, it is preferable that the aerosol cartridge housing 810 forms a cavity having an opening at the bottom, the top of the aerosol cartridge housing 810 extends toward the inside of the cavity to form the liquid storage element through-hole 130, and the first housing base 823 is inserted into the cavity from the bottom of the aerosol cartridge housing 810 to form the liquid storage element 100 together with the aerosol cartridge housing 810. An installation space for installing the atomizing core 930 is formed between the first housing base 823 and the wall portion of the liquid storage element through hole 130. The liquid storage element through hole 130 is used as an aerosol channel 1303 at the same time, the upper part of the atomization core 930 is tightly matched and sealed with the atomization module connection port 1302 at the lower part of the aerosol channel 1303, and the lower part of the atomization core 930 is tightly matched and sealed with the atomization core assembly port 826 at the middle part of the first housing base 823. The first housing base 823 is formed with an independent air guide member mounting hole 660 penetrating the first housing base 823 for mounting the independent air guide member 600. The second housing base 824 is spaced apart from the first housing base 823 for sealing the bottom opening of the aerosol cartridge housing 810 and forming a buffer chamber 828 between the first housing base 823 and the second housing base 824, and the separate air guide element 600 communicates with the liquid storage element 100 and the buffer chamber 828.

Preferably, an elastomer (such as silica gel) may be disposed between the upper portion of the atomizing core 930 and the atomizing module connection port 1302 at the lower portion of the aerosol passage 1303, and between the lower portion of the atomizing core 930 and the atomizing core assembly port 826, to increase the sealing effect between the atomizing core 930 and the atomizing module connection port 1302 and the atomizing core assembly port 826, thereby avoiding leakage of external air into the liquid storage element 100 through the mounting portion of the atomizing core 930, and further ensuring that external air can only enter the liquid storage element 100 through the independent air guide element 600.

As shown in FIG. 1, the individual gas guide elements 600 are mounted on the first housing base 823 and extend into the buffer chamber 828, preferably the individual gas guide elements 600 extend into the buffer chamber 828 to a depth exceeding 50% of the depth of the buffer chamber 828, more preferably the individual gas guide elements 600 extend into the buffer chamber 828 to a depth exceeding 80% of the depth of the buffer chamber 828, and most preferably the individual gas guide elements 600 extend into the buffer chamber 828 and are proximate to the second housing base 824.

As shown in fig. 1, in the present embodiment, the aerosol bomb 800 includes a separator tube 829 that communicates with the base through hole 1122 of the aerosol bomb 800 and extends toward the atomizing core 930. One end of the isolation tube 829 is connected with the second housing base 824, the other end of the isolation tube 829 is close to the atomization core 930, and an air guide hole 827 communicated with the buffer chamber 828 is formed in a position, close to the atomization core 930, of the top wall or the side wall of the isolation tube 829. Preferably, the spacer 829 is fabricated from silicone. Preferably, the isolation tube 829 is connected to the atomizing core 930 (not shown), that is, there is no space between the isolation tube 829 and the atomizing core 930, and an air vent 827 is provided at a portion of the sidewall of the isolation tube 829 near the atomizing core 930, which communicates with the buffer chamber 828. Preferably, the air-guide hole 827 is composed of a plurality of small holes through which the atomized liquid can be guided. When the atomized liquid leaks from the buffer chamber 828, the isolation tube 829 can effectively prevent the atomized liquid in the buffer chamber 828 from leaking out of the aerosol cartridge 800 from the base through hole 1122 or the aerosol passage 1303.

In this embodiment, the aerosol bomb 800 includes a buffer chamber 828 that communicates with the atmosphere and a separator tube 829 that communicates the base through-hole 1122 with the atomizing core 930. The independent air guide element 600 is disposed on the first housing base 823, and one end of the independent air guide element 600 is connected to the liquid storage element 100, and the other end is connected to the buffer chamber 828 between the first housing base 823 and the second housing base 824. The liquid storage element 100 communicates with the buffer chamber 828 between the first housing base 823 and the second housing base 824 through the independent air guide element 600, and communicates with the outside atmosphere through the air guide hole 827 of the isolation tube 829, and the base through hole 1122. External atmosphere enters the liquid storage element 100 through the air inlet 1121, the base through hole 1122, the air guide hole 827, the buffer chamber 828 between the first housing base 823 and the second housing base 824, and the independent air guide element 600, thereby achieving communication between the liquid storage element 100 and external atmosphere through the independent air guide element 600.

After the aerosol bomb 800 is assembled, the independent air guide element 600 absorbs enough liquid, the independent air guide element through hole 630 is sealed by liquid, the atomization core liquid guide element 932 absorbs the liquid in the liquid storage element 100, the negative pressure in the liquid storage element 100 is increased until reaching an equilibrium state, and the liquid content of the atomization core liquid guide element 932 reaches a certain degree.

< atomizing core >

As shown in fig. 4, in the present embodiment, the atomizing core 930 includes a tubular atomizing core housing 9324, a tubular atomizing core liquid guiding element 932 closely attached to an inner peripheral wall of the atomizing core housing 9324, an atomizing core liquid guiding element through-hole 932b axially penetrating the atomizing core liquid guiding element 932, and a heating element 931 attached to the inner peripheral wall of the atomizing core liquid guiding element 932.

The atomizing core housing 9324 is provided with a housing liquid-guiding through hole 9325, and the atomizing core liquid-guiding member 932 seals the housing liquid-guiding through hole 9325 and contacts the atomized liquid in the liquid-storing member 100 through the housing liquid-guiding through hole 9325.

The atomizing core liquid guiding element through hole 932b constitutes an atomizing chamber 934 at a portion having the heating element 931. The liquid-guiding through hole 9325 of the atomization core 930 may be hollowed out on the atomization core housing 9324.

To further reduce the risk of air leakage and liquid leakage of the atomizing core 930, it is preferred that OL1 is greater than 1.2mm, 1.5mm or 1.8mm, and that OL2 is greater than 1.2mm, 1.5mm or 1.8mm. When the OL1 and the OL2 are larger than 1.2mm, in addition to effectively preventing external air from entering the liquid storage element 100 through the parts where the upper and lower edges of the atomizing core liquid guiding element 932 are closely adhered to the atomizing core outer housing 9324 in normal use, leakage and leakage of the atomizing core 930 can be effectively prevented even if adverse environments such as high, low temperature, low pressure, vibration and the like are encountered during storage and transportation.

The atomizing core liquid transfer element 932 may include more than two layers (including two layers) of liquid transfer cloth.

The atomizing core liquid guiding element 932 is closely adhered to the inner peripheral wall of the atomizing core housing 9324. The close adherence of the nebulizing core liquid guiding element 932 to the inner peripheral wall of the nebulizing core housing 9324 can prevent external air from entering the liquid storage element 100 through the nebulizing core 930.

When the liquid guiding cloth is soft, more than two layers (including two layers) of liquid guiding cloth are adopted, and as the number of layers of liquid guiding cloth is increased, the strength of the atomizing core liquid guiding element 932 is increased, and the effect of tightly attaching to the inner peripheral wall of the atomizing core housing 9324 and effectively blocking the housing liquid guiding through hole 9325 is also increased.

Preferably, the atomizing core liquid transfer element 932 includes 4 to 7 layers of liquid transfer cloth. When the liquid guiding cloth is greater than or equal to 4 layers and less than or equal to 7 layers, the effect of tightly attaching to the inner peripheral wall of the atomizing core shell 9324 and effectively blocking the liquid guiding through hole 9325 of the shell can be further improved, and meanwhile, the speed of liquid penetrating from the liquid storage element 100 to the heating element 931 through the liquid guiding cloth can be ensured, so that the high-quality atomizing effect can be achieved.

The liquid guiding cloth is preferably made of fibers resistant to high temperature, such as spunlaced cloth, needled cloth, woven cloth and the like made of cotton fibers, viscose fibers, flax fibers or carbon fibers and the like, and is preferably coated with flax fibers and a heating element 931.

At least one layer of liquid guiding cloth comprises grains, the grains comprise micro-edges and/or micro-grooves, the micro-edges and/or the micro-grooves on the liquid guiding cloth are beneficial to forming micro-spaces for storing atomized liquid when the liquid guiding cloth layers are mutually overlapped, and the probability of liquid shortage of the atomized core liquid guiding element 932 during atomization is reduced. The grain direction of the liquid guiding cloth refers to the overall extending direction of the micro-ribs and/or micro-grooves on the liquid guiding cloth, for example, the grains on the liquid guiding cloth extend along the radial direction or the axial direction of the atomizing core 930, but each grain is not required to extend strictly along the radial direction or the axial direction of the atomizing core 930, and can also be branch grains with partial grains extending along other directions on the basis of the radial direction or the axial direction of the grains.

The lines on the liquid guiding cloth are usually generated in the production or post-processing process of the liquid guiding cloth, the height of the micro-ribs and the depth of the micro-grooves are usually not more than one hundred micrometers, for example, the water jet cloth usually generates overall lines along the equipment direction (machine direction, abbreviated as MD) in production, but the arrangement mode of some water needle holes can be designed on a water needle plate for producing the water jet cloth, so that the water jet cloth extends to branch lines in other directions along the overall lines of the equipment direction.

When the liquid guiding cloths are attached to each other or the liquid guiding cloths are attached to the inner wall of the atomizing core housing 9324, the overall extending direction of the grains on the liquid guiding cloths enables the formed micro grooves and micro ribs to become passages favorable for liquid flow.

In the present utility model, it is preferable that the direction of the grain of the liquid guiding cloth attached to the inner peripheral wall of the atomizing core housing 9324 is along the radial direction of the atomizing core 930. Thus, when the atomized liquid contacts the liquid guiding cloth closely attached to the inner wall of the atomizing core housing 9324 through the housing liquid guiding through hole 9325 of the atomizing core housing 9324, the liquid is facilitated to flow on the liquid guiding cloth in the radial direction of the atomizing core 930. In addition, when the liquid guiding element is tightly adhered to the inner peripheral wall of the atomizing core housing 9324 and is infiltrated by the atomized liquid, the micro ribs and/or micro grooves radially distributed along the atomizing core 930 play a role in blocking the external air from entering the liquid storage element 100 through the gap between the atomizing core housing 9324 and the liquid guiding cloth, so that the external air can be effectively blocked from entering the liquid storage element 100 through the atomizing core 930. Thus, during normal use of the aerosol bomb 800, external air can only enter the liquid storage element 100 through the independent air guide element 600, so that the negative pressure and atomization stability in the liquid storage element 100 are improved.

In this embodiment, it is preferable that the direction of the pattern of the liquid guiding cloth contacting with the heating element 931 is along the axial direction of the atomizing core 930. The direction of the pattern of the liquid guiding cloth contacting the heating element 931 is substantially consistent with the pattern of a portion of the heating element 931, which facilitates the flow and conduction of liquid between the liquid guiding cloth and the heating element 931.

In this embodiment, the atomizing core liquid guiding element 932 preferably includes at least two layers of liquid guiding cloth with non-uniform grain directions, and more preferably, the atomizing core liquid guiding element 932 includes at least one layer of liquid guiding cloth with grain directions along the axial direction of the atomizing core 930 and at least one layer of liquid guiding cloth with grain directions along the radial direction of the atomizing core 930. This configuration facilitates the simultaneous radial and axial flow of liquid in the atomizing core liquid guide element 932, increases the liquid feed rate of the atomizing core 930, and reduces the likelihood of liquid starvation of the atomizing core liquid guide element 932 during rapid atomization.

In the present utility model, the heating element 931 may be attached to or partially embedded in the inner wall of the atomizing core liquid guide element 932.

Since the atomizing core 930 according to the present utility model cannot supplement the gas into the liquid storage member 100 under normal operation, the atomizing core 930 according to the present utility model alone cannot smoothly atomize the liquid when used in the aerosol dispensing device 1 in the absence of the independent gas guide member 600. If the separate air guide element 600 is absent, the negative pressure in the liquid storage element 100 will continuously rise as atomization proceeds, resulting in insufficient liquid supply to the atomization core liquid guide element 932 and burning of the atomization core 930.

As shown in fig. 4, in the present utility model, the atomizing core 930 further includes an atomizing core base 935 and a wire 933 connected to the heating element 931, the wire 933 being fixed to the atomizing core base 935. Preferably, the atomizing core base 935 is disposed within the atomizing core housing 9324 and below the atomizing core liquid guide element 932.

An aerosol electrode 936 may be provided on the aerosol 800, and one end of the aerosol electrode 936 may be connected to the lead 933 by welding, riveting or crimping, and the other end of the aerosol electrode 936 may be connected to the main body electrode 954 of the aerosol dispensing device 1 by plugging, spring crimping or magnetic contact.

When the aerosol bullet electrode 936 is electrically connected with the outside by a spring plate crimping or plugging mode, preferably, the aerosol bullet electrode 936 is columnar, and the columnar aerosol bullet electrode 936 can be made by cutting a metal wire. Such aerosol electrode 936 does not need to be specially machined to form a large contact area, and the manufacturing cost of the aerosol electrode 936 can be significantly reduced. To facilitate electrical connection of the aerosol electrode 936 to an external socket, the end face of the cylindrical aerosol electrode 936 may be chamfered.

In the present utility model, the aerosol bomb 800 further comprises an atomizing core reinforcing core 9326 that axially passes through the atomizing core liquid conductor element through-hole 932b and is covered by the atomizing core liquid conductor element 932 and the heating element 931. After the aerosol bomb is filled with liquid, the atomizing core reinforcing core body can strengthen the strength of the atomizing core liquid guide element 932 and the compactness of the atomizing core liquid guide element attached to the inner wall of the atomizing shell. The atomizing core reinforcing core 9326 prevents the atomizing core liquid guiding element 932 and the heating element 931 from deforming or loosening during product storage and transportation, and keeps the performance of the aerosol bomb 800 stable.

As shown in fig. 1, in the present utility model, the independent air guide element 600 is independent of the atomizing core liquid guide element 932, i.e., the atomizing core liquid guide element 932 does not participate in the peripheral wall constituting the independent air guide element through hole 630. Unlike prior art air guide channels formed by the participation of the liquid guide channels, the atomizing core liquid guide element 932 of the present utility model does not participate in forming the air guide channel of the independent air guide element 600, nor does the independent air guide element 600 participate in providing liquid to the atomizing core 930.

In aerosol bomb 800, individual gas guide elements 600 may be provided in one or more.

As shown in fig. 5 to 8, in the present utility model, the independent air guide element 600 includes an independent air guide element core 640 and at least one independent air guide element through hole 630 axially penetrating the independent air guide element 600. In this embodiment, the individual air guide element through holes 630 serve as the only air guide channels for the aerosol bomb 800.

In this embodiment, the independent air guide element core 640 may be made of a non-porous material such as plastic or metal. The individual gas guide elements 600 may also be made of sintered plastic powder.

In this embodiment, the independent air guiding element core 640 may also be made of a porous material, preferably, the independent air guiding element core 640 is made of fiber bonding, and the sensitivity of the independent air guiding element 600 is improved due to the fast penetration of the liquid in the bonding fiber. More preferably, the individual air guide element cores 640 are formed by bonding fibers of a sheath-core structure, which are bonded without the use of a binder and heated to form a bond that reduces the risk of hazardous materials.

Preferably, the sheath of the sheath-core structural fiber is polyethylene, polypropylene, polybutylene succinate (PBS), a copolymer of polybutylene adipate and terephthalate (PBAT), a copolyester of polyethylene terephthalate (Co-PET), polytrimethylene terephthalate (PTT), polybutylene terephthalate (PBT), polyamide 6, or the like.

The minimum cross-section of the individual air guide element through holes 630 has a maximum inscribed circle diameter of 0.1mm to 1.5mm, such as 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.2mm, 1.5mm, etc. When the viscosity of the liquid to be atomized is small or the required atomization amount is small, a small independent air guide element through hole 630 may be provided; when the viscosity of the liquid to be atomized is high or the required amount of atomization is high, a large independent air guide member through hole 630 may be provided. The cross-section of the individual air guide element through holes 630 may be provided in various geometric shapes, such as circles, sectors, rings, polygons, etc.

When the independent air guide element 600 contacts the liquid, the liquid wets the independent air guide element 600 and hydraulically seals the independent air guide element through hole 630 under the action of capillary force. The strength of the liquid seal is determined by the viscosity and surface tension of the liquid, the materials of the individual air guide element core 640 and the individual air guide element jacket 650, the size of the individual air guide element through holes 630, and the like.

< Aerosol bullet >

In the present utility model, the aerosol bomb 800 comprises a detachable liquid storage module and an atomization module, the liquid storage module at least comprises a liquid storage element 100, the atomization module at least comprises an atomization core 930, and the liquid storage module and the atomization module are spliced to form the aerosol bomb 800.

Specifically, as shown in fig. 2, the liquid storage module may be a module formed by integrating the aerosol cartridge housing 810 and the first housing base 823, the atomization module may be a module formed by integrating the atomization core 930 and the second housing base 824, and structures capable of being mutually inserted are respectively arranged on the liquid storage module and the atomization module, so that the assembly of the aerosol cartridge 800 can be simply completed, and the replacement of the liquid storage element 100 is facilitated.

Fig. 9 is a schematic structural view of another aerosol cartridge according to the first embodiment of the present utility model. As shown in fig. 9, in the present embodiment, the aerosol bomb 800 further includes an aerosol passage 1303 and a condensate absorbing element 400 provided in the aerosol passage 1303. For absorbing condensate that may be generated in the aerosol, can enhance the experience of a user who prefers dry smoke.

As shown in fig. 9, when the independent air guide element core 640 is made of a non-porous material such as plastic or metal, it is preferable to provide a porous material pad 843 abutting the independent air guide element 600 at the lower end of the independent air guide element 600, the porous material pad 843 may be made of fiber bonding, and the density is less than 0.1g/cm ³ . When the atomized liquid leaks from the independent air guide member through holes 630 under abnormal conditions, the liquid is preferentially absorbed by the porous material pad 843, and when the environment returns to normal, part of the liquid in the porous material pad 843 can return to the liquid storage member 100 through the independent air guide member through holes 630. When the liquid in the liquid storage element 100 is consumed by atomization, external air may penetrate through the porous material pad 843 into the individual air guide element through holes 630 and replenish the liquid storage element 400.

Preferably, a porous material pad 843 is provided at the bottom of the buffer chamber 828. When liquid in the liquid storage element 100 leaks into the buffer chamber 828 under normal circumstances, the porous material pad 843 may absorb the leaked liquid and return the leaked liquid to the liquid storage element 100 through the separate air guide element 600.

Preferably, the separate air guide element 600 and the first housing base 823 are integrally formed.

Second embodiment

Fig. 10 is a schematic structural view of an aerosol bomb according to a second embodiment of the present utility model. The present embodiment is similar to the first embodiment in structure, and the same parts as those of the first embodiment are not described in detail in the description of the present embodiment.

This embodiment differs from the first embodiment in that according to the aerosol cartridge 800 of the second embodiment, an aerosol cartridge electrode 936 is provided, the aerosol cartridge electrode 936 is mounted at the bottom of the second housing base 824, one end of the aerosol cartridge electrode 936 is connected to the lead 933 of the atomizing core 930, and the other end of the aerosol cartridge electrode 936 is electrically connected to the main body electrode 954 in the aerosol dispensing device 1, preferably both are magnetically connected.

According to the aerosol bomb 800 of the present embodiment, the aerosol bomb 800 can be detachably mounted in the aerosol-emitting device 1, so that the replacement of the aerosol bomb 800 in the aerosol-emitting device 1 is facilitated.

In addition, in this embodiment, an aerosol cartridge with a liquid injection port is further provided, and the liquid injection port 841 may be provided on the liquid storage element 100 of any aerosol cartridge 800 of the present utility model, preferably, the liquid injection port 841 is provided on a side wall of the liquid storage element 100, so as to facilitate the injection of the atomized liquid during the assembly or use of the aerosol cartridge 800. The port 841 is sealed by the port sealing member 842.

When the aerosol cartridge 800 is provided with the liquid filling port 841, the individual air guide members 600 are preferably provided as one.

When the independent air guide elements are arranged as one, the liquid injection port 841 is arranged at a position near the independent air guide element on the liquid storage element 100. In the present utility model, the position near the independent air guide element has a special meaning, and refers to the arrangement position of the liquid injection port 841 on the liquid storage element 100, which enables the independent air guide element 600 to be in contact with liquid at the latest when liquid is injected. For example, when the liquid storage element 100 is a cuboid, the side surface near the independent air guiding element 600 can be regarded as a near independent air guiding element position, and when the liquid storage element 100 is a cylinder, the liquid storage element has a bus line with the shortest distance from the central axis of the independent air guiding element 600, so that the position of the center of the liquid injection port 841 on the bus line is regarded as a near independent air guiding element position.

When the aerosol container 800 is provided with the liquid injection port 841, according to the aerosol container 800 of the present utility model, since the atomizing core liquid guiding element 932 is tightly adhered to the inner peripheral wall of the atomizing core housing 9324, the minimum height OL1 of the tightly adhered portion of the atomizing core housing 9324 and the liquid guiding element 932 above the housing liquid guiding through hole 9325 is greater than 0.8mm, and the minimum height OL2 of the tightly adhered portion of the atomizing core housing 9324 and the liquid guiding element 932 below the housing liquid guiding through hole 9325 is greater than 0.8mm, it is possible to effectively prevent liquid from leaking from the atomizing core 930 during liquid injection.

When the liquid injection port 841 is disposed on the side wall of the liquid storage element 100 near the independent air guide element, the independent air guide element 600 will contact the liquid when the liquid injection is near the completion, so that the liquid can be effectively prevented from leaking from the independent air guide element 600 when the liquid is injected.

As shown in fig. 10, the aerosol bomb 800 according to the second embodiment of the present utility model includes an atomized core reinforcement core 9326. The atomizing core reinforcing core 9326 axially passes through the atomizing core liquid conductor through-hole 932b and is covered by the atomizing core liquid conductor 932 and the heating element 931.

After the aerosol is injected into the liquid, the liquid is absorbed by the atomization core liquid guiding element 932, and under the condition that the atomization core strengthening core 9326 is not provided, the liquid guiding element 932 of the atomization core can be swelled and deformed, and the swelling and deformation of the two ends of the liquid guiding element 932 of the atomization core are often more serious, so that the compactness of the two ends of the liquid guiding element 932 of the atomization core and the inner wall of the shell 9324 of the atomization core can be damaged, the air leakage and the liquid leakage of the atomization core can be caused, and even the whole atomization function can be disabled. When the aerosol comprises the atomizing core reinforcing core 9326, the aerosol is limited by the space between the atomizing core housing 9324 and the atomizing core reinforcing core 9326, after the aerosol is filled with liquid, the atomizing core liquid guiding element 932 absorbs the liquid, and the fiber liquid in the atomizing core liquid guiding element 932 swells and extrudes mutually, so that the strength of the atomizing core liquid guiding element 932 is improved, and the adhesion between the atomizing core liquid guiding element and the atomizing core housing 9324 is tighter, thereby further enhancing the effectiveness of the whole atomizing system. Thanks to the characteristic of the relaxation properties of the polymer chain, even if the atomizing core reinforcing core 9326 is pulled out after a period of time, the atomizing core liquid guiding element 932 will not deform significantly, thereby eliminating the risk of leakage or failure of the atomizing system that may exist in the aerosol.

In addition, during product storage and transportation, the atomizing core reinforcing core 9326 can effectively prevent the atomizing core liquid guiding element 932 and the heating element 931 from deforming or loosening, so that the performance of the aerosol bomb 800 can be kept stable.

In use, the atomizing core reinforcing core 9326 is pulled out.

Third embodiment

The present embodiment is similar to the first embodiment in structure, and the same parts as those of the first embodiment are not described in detail in the description of the present embodiment. The difference is that,

as shown in fig. 11 to 13, the aerosol 80 according to the third embodiment of the present utility model atomizes the core 930, the liquid storage element 100 that supplies the liquid to the atomizing core 930, and the independent air guide element 600 that communicates the liquid storage element 100 with the external atmosphere; the atomizing core 930 includes a tubular atomizing core housing 9324, a tubular atomizing core liquid guiding element 932 closely adhered to an inner peripheral wall of the atomizing core housing 9324, an atomizing core liquid guiding element through-hole 932b axially penetrating the atomizing core liquid guiding element 932, and a heating element 931 adhered to the inner peripheral wall of the atomizing core liquid guiding element 932; the atomization core housing 9324 is provided with a housing liquid guide through hole 9325, and the atomization core liquid guide element 932 seals the housing liquid guide through hole 9325 and contacts with the atomized liquid in the liquid storage element 100 through the housing liquid guide through hole 9325; the minimum height OL1 of the close-fitting part of the atomizing core outer shell 9324 and the liquid guiding element 932 above the outer shell liquid guiding through hole 9325 is larger than 0.8mm, and the minimum height OL2 of the close-fitting part of the atomizing core outer shell 9324 and the liquid guiding element 932 below the outer shell liquid guiding through hole 9325 is larger than 0.8mm; the aerosol cartridge 800 further comprises an aerosol cartridge housing 810 and a second housing base 824 disposed at the bottommost portion of the aerosol cartridge housing 810, a first housing base 823 disposed inside the aerosol cartridge housing 810 and spaced from the second housing base 824, and a buffer chamber 828 disposed between the first housing base 823 and the second housing base 824, wherein the independent air guide element 600 communicates with the liquid storage element 100 and the buffer chamber 828.

In this embodiment, the independent air guide element 600 includes an independent air guide element core 640, and the contact angle of the independent air guide element core 640 to the atomized liquid is greater than 90 °. The individual air guide element core 640 comprises a porous material such as bonded fibers, sponge, or film that is surface treated with an organic fluorine or silicone. Because the contact angle of the independent air guide element core 640 to the atomized liquid is greater than 90 °, when the aerosol bomb 800 works, external air can be supplemented from the independent air guide element 600 into the liquid storage element 100 through the buffer chamber 828, but the atomized liquid cannot be guided out to the buffer chamber 828 through the independent air guide element 600.

In this embodiment, the independent air guide element 600 may not be provided with the independent air guide element through hole 630 and the independent air guide element housing 650. The individual air guide elements 600 may be directly fitted into the individual air guide element mounting holes 660 provided on the first housing base 823.

The aerosol cartridge 800 according to the third embodiment of the present utility model further comprises a buffer liquid guiding element 670. In the present utility model, the buffer liquid guiding element 670 can only guide liquid but not air during normal use, and the buffer liquid guiding element 670 communicates the liquid storage element 100 and the buffer chamber 828.

In the aerosol bomb 800 according to the third embodiment of the present utility model, the separate air guide member 600 and the buffer liquid guide member 670 communicate with the liquid storage member 100 and the buffer chamber 828. Under abnormal conditions, the liquid in the liquid storage element 100 is led out from the buffer liquid guiding element 670 and temporarily stored in the buffer chamber 828, and the isolation tube 829 connected with the base through hole 1122 of the aerosol bomb 800 can effectively prevent the liquid in the buffer chamber 828 from leaking. After the environment returns to normal, the temporarily stored liquid in the buffer chamber 828 returns to the liquid storage element 100 via the buffer liquid guiding element 670, so that the waste of atomized liquid is avoided, and the risk of liquid leakage to the outside of the aerosol bomb 800 during the liquid storage and use is reduced.

As shown in fig. 14 and 15, the mist bomb 80 according to the fourth embodiment of the present utility model includes an atomizing core 930, a liquid storage member 100 that supplies liquid to the atomizing core 930, and a separate air guide member 600 that communicates the liquid storage member 100 with the external atmosphere; the atomizing core 930 includes a tubular atomizing core housing 9324, a tubular atomizing core liquid guiding element 932 closely adhered to an inner peripheral wall of the atomizing core housing 9324, an atomizing core liquid guiding element through-hole 932b axially penetrating the atomizing core liquid guiding element 932, and a heating element 931 adhered to the inner peripheral wall of the atomizing core liquid guiding element 932; the atomization core housing 9324 is provided with a housing liquid guide through hole 9325, and the atomization core liquid guide element 932 seals the housing liquid guide through hole 9325 and contacts with the atomized liquid in the liquid storage element 100 through the housing liquid guide through hole 9325; the minimum height OL1 of the close-fitting part of the atomizing core outer shell 9324 and the liquid guiding element 932 above the outer shell liquid guiding through hole 9325 is larger than 0.8mm, and the minimum height OL2 of the close-fitting part of the atomizing core outer shell 9324 and the liquid guiding element 932 below the outer shell liquid guiding through hole 9325 is larger than 0.8mm; the aerosol cartridge 800 further comprises an aerosol cartridge housing 810 and a second housing base 824 disposed at the bottommost portion of the aerosol cartridge housing 810, a first housing base 823 disposed inside the aerosol cartridge housing 810 and spaced from the second housing base 824, and a buffer chamber 828 disposed between the first housing base 823 and the second housing base 824, wherein the independent air guide element 600 communicates with the liquid storage element 100 and the buffer chamber 828.

In this embodiment, the independent air guide element 600 includes an independent air guide element core 640, and the contact angle of the independent air guide element core 640 to the atomized liquid is smaller than 90 °. The independent air guide element core 640 is a porous material having a contact angle with an atomized liquid of less than 90 ° and no independent air guide element through holes 630. When the atomized liquid in the aerosol bomb is consumed, the negative pressure in the liquid storage element is increased, the liquid in the independent air guide element 600 is partially sucked back into the liquid storage element, and after the independent air guide element loses part of the liquid, external air can enter the liquid storage element through the independent air guide element.

Preferably, the independent air guiding element 600 comprises a high capillary porous body 601 and a low capillary porous body 602, when the liquid in the independent air guiding element 600 is sucked back into the liquid storage element, the high capillary porous body 601 can absorb the liquid from the low capillary porous body 602 due to the difference of capillary forces of the high capillary porous body and the low capillary porous body, so that the low capillary porous body 602 loses more liquid to generate better air guiding capability, and external air can be supplemented into the liquid storage element 100 through the low capillary porous body 602.

Fifth embodiment

FIG. 16 is a schematic view showing the structure of a first aerosol-emitting device according to a fifth embodiment of the present utility model; FIG. 17 is a schematic view showing the structure of a second aerosol-emitting device according to a fifth embodiment of the present utility model; FIG. 18 is a schematic view showing the structure of a third aerosol-emitting device according to a fifth embodiment of the present utility model; FIG. 19 is a schematic view showing the structure of a fourth aerosol-emitting device according to a fifth embodiment of the present utility model; FIG. 20 is a schematic view showing the structure of a fifth aerosol-emitting device according to a fifth embodiment of the present utility model; FIG. 21 is a schematic view showing the structure of a sixth aerosol-emitting device according to a fifth embodiment of the present utility model; fig. 22 is a schematic structural view of a seventh aerosol-emitting device according to a fifth embodiment of the present utility model.

The aerosol-emitting device 1 according to the fifth embodiment of the present utility model includes any one of the aerosol bombs 800 described above.

The aerosol dispensing device 1 further includes a main body case 950 having an opening at one end for housing the aerosol cartridge 800, a main body battery 955 provided in the main body case 950, and a main body control circuit 956 provided in the main body case 950.

As shown in fig. 16, in the first aerosol-emitting device 1 according to the fifth embodiment of the present utility model, the lead 933 of the aerosol cartridge 800 extends into the main body case 950 and is soldered to the main body control circuit 956. The aerosol cartridge 800 is inserted into the main housing 950 and is sealed in close-fitting relation to the main housing 950.

As shown in fig. 17, a second aerosol-emitting device according to a fifth embodiment of the present utility model is similar in structure to the first aerosol-emitting device according to the fifth embodiment of the present utility model, except that the second aerosol-emitting device 1 according to the fifth embodiment of the present utility model further comprises an aerosol outlet sealing element 1306 and a host air inlet sealing element 957. An aerosol outlet sealing element 1306 is used to seal the aerosol outlet 1301 of the aerosol cartridge 800 and a host air inlet sealing element 957 is used to seal the air inlet of the aerosol dispensing device 1.

By providing aerosol outlet seal 1306 and host air inlet seal 957, leakage of aerosol dispensing device 1 during storage and transportation is prevented.

In use, the aerosol outlet seal 1306 and the host air inlet seal 957 of the aerosol dispensing device 1 are pulled apart and the liquid on the atomizing wick liquid guide 932 is heated to atomize and the aerosol generated in the atomizing chamber 934 escapes through the aerosol passage 1303. The atomizing wick liquid transfer element 932 absorbs liquid from the liquid storage element 100 and supplements around the heating element 931. As the liquid is drawn out, the negative pressure within the liquid storage element 100 increases and the liquid in the individual air guide element 600 gradually returns to the liquid storage element 100 until the liquid seal of the individual air guide element through hole 630 opens. External air enters the liquid storage element 100 through the independent air guide element through holes 630, so that the negative pressure in the liquid storage element 100 is reduced, the independent air guide element through holes 630 are sealed again by liquid, and the process is repeatedly performed, so that the atomization process can be continuously performed until the liquid in the liquid storage element 100 is used up.

Under abnormal conditions, such as a decrease in external pressure or an increase in temperature, the negative pressure within the reservoir member 100 decreases, and liquid is guided out of the separate air guide member 600 and temporarily stored in the buffer chamber 828, thereby avoiding leakage of liquid from the aerosol bomb 800.
