Description

Aerosol bomb, aerosol bomb with liquid injection port and aerosol dispersing device Technical Field

The present invention relates to an aerosol bomb, an aerosol bomb with a liquid injection port and an aerosol dispersing device, and in particular to an aerosol bomb with an independent air guide element, an aerosol bomb with a liquid injection port and an aerosol dispersing device used in application fields such as electronic cigarettes and drug solution atomization.

Background technique

Atomization technology is widely used in electronic cigarettes and other fields. A common technology in electronic cigarettes is to heat the atomization core liquid guide element directly connected to the e-liquid to atomize the liquid.

For example, in a conventional aerosol bomb design, the heating element in the aerosol bomb heats the glass fiber bundle or cotton fiber bundle that passes through the atomization chamber cavity, and the liquid is atomized in the atomization chamber cavity and then discharged from the aerosol channel. This aerosol bomb needs to make the atomization chamber cavity and the atomization core liquid guide element "appropriately" cooperate, so that the liquid is conducted from the atomization core liquid guide element while allowing external air to enter the liquid storage element from the gap inside the atomization core liquid guide element or the gap between the atomization core liquid guide element and the atomization chamber cavity, thereby avoiding the negative pressure in the liquid storage element from continuing to increase after the liquid is consumed. Because the liquid guide elements such as glass fiber bundles, cotton fiber bundles and non-woven fabrics are soft and lack a fixed shape, it is difficult to precisely control the gap inside the atomization core liquid guide element and between the atomization core liquid guide element and the atomization chamber cavity. If the gap is too small, it is difficult for air to enter the liquid storage element, which leads to the atomization core lacking liquid and sticking the core; when the gap is too large, liquid accumulates on the atomization core, and oil explodes during atomization. In severe cases, liquid will leak from the atomization core and be inhaled into the consumer's mouth or leak from the aerosol bomb, all of which affect the stability of atomization and consumer experience. In addition, in the prior art, the atomized liquid cannot return to the liquid storage element after leaking out of the gap, thus wasting the atomized liquid.

In another conventional aerosol bomb design, the atomized liquid is stored in a liquid storage element made of bonding fibers. The liquid in the liquid storage element is transmitted to the atomizer core liquid guide element through the liquid guide holes on the atomizer core shell. The heating element heats the liquid on the atomizer core liquid guide element. The liquid escapes from the aerosol channel after being atomized in the atomization chamber. In order to allow external air to replenish and enter the liquid storage element so that atomization can proceed smoothly, the liquid guide holes of the atomizer core shell are not completely blocked by the atomizer core liquid guide element, or an independent through hole that is not blocked by the atomizer core liquid guide element is provided on the atomizer core shell. Since the atomized liquid is pulled by the capillary force of the bonding fiber, the aerosol bomb is not easy to leak, but as the liquid in the bonding fiber is released, the ability of the bonding fiber to release liquid continues to decay, resulting in a decline in the atomization amount and taste, affecting the consumer experience.

First embodiment

Fig. 1 is a schematic diagram of the structure of an aerosol bomb according to the first embodiment of the present invention; Fig. 2 is a schematic diagram of the first structural decomposition of the aerosol bomb shown in Fig. 1; Fig. 3 is a schematic diagram of the second structural decomposition of the aerosol bomb shown in Fig. 1; and Fig. 4 is a schematic diagram of the cross-sectional structure of the atomizing core shown in Fig. 1.

As shown in FIGS. 1 to 4 , an aerosol bomb 800 according to a first embodiment of the present invention comprises an atomizing core 930, a liquid storage element 100 for supplying liquid to the atomizing core 930, and an independent air guide element 600 for connecting the liquid storage element 100 with the external atmosphere; the atomizing core 930 comprises a tubular atomizing core shell 9324, a tubular atomizing core liquid guide element 932 tightly attached to the inner circumferential wall of the atomizing core shell 9324, an atomizing core liquid guide element through hole 932b axially penetrating the atomizing core liquid guide element 932, and a heating element 931 attached to the inner circumferential wall of the atomizing core liquid guide element 932; a shell liquid guide through hole 9325 is provided on the atomizing core shell 9324, the atomizing core liquid guide element 932 blocks the shell liquid guide through hole 9325, and is connected to the liquid storage element 100 through the shell liquid guide through hole 9325. 00; the minimum height OL1 of the atomizer core shell 9324 above the shell liquid conducting hole 9325 and the liquid conducting element 932 tightly covering the minimum height OL2 of the atomizer core shell 9324 below the shell liquid conducting hole 9325 and the liquid conducting element 932 tightly covering the minimum height OL2 is greater than 0.8mm; the aerosol bomb 800 also includes an aerosol bomb shell 810 and a second shell base 824 arranged at the bottom of the aerosol bomb shell 810, a first shell base 823 arranged inside the aerosol bomb shell 810 and spaced from the second shell base 824, and a buffer chamber 828 arranged between the first shell base 823 and the second shell base 824, and the independent gas guide element 600 communicates with the liquid storage element 100 and the buffer chamber 828.

The close contact of the atomizer core liquid guide element 932 with the inner wall of the atomizer core shell 9324 has a special meaning in the present invention, which means that after the liquid storage element 100 is filled with atomized liquid, external air cannot enter the liquid storage element 100 through the atomizer 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 component 100 through the independent air guide element 600. Since the atomizer core 930 according to the present invention cannot replenish gas into the liquid storage component 100 under normal use, if the independent air guide element 600 is removed, the atomizer core 930 according to the present invention cannot normally atomize liquid in the aerosol dispensing device 1 described later.

The minimum height OL1 of the tightly-fitting portion between the atomizer core housing 9324 and the liquid-conducting element 932 above the liquid-conducting through hole 9325 of the housing is greater than 0.8 mm, preferably greater than 1.2 mm, 1.5 mm or 1.8 mm; the minimum height OL2 of the tightly-fitting portion between the atomizer core housing 9324 and the liquid-conducting element 932 below the liquid-conducting through hole 9325 of the housing is greater than 0.8 mm, preferably greater than 1.2 mm, 1.5 mm or 1.8 mm.

When the atomized liquid is just injected into the aerosol cartridge, as long as the minimum height of the tightly-attached portions of the atomizer core housing 9324 and the liquid guide element 932 above and below the housing liquid guide hole 9325 is greater than 0.5 mm, external air can be prevented from entering the liquid storage element 100 through the tightly-attached portions of the upper and lower edges of the atomizer core liquid guide element 932 and the atomizer core housing 9324. However, as time goes by, the liquid-guiding cloth will gradually swell and deform after being soaked by the atomized liquid, and the swelling and deformation of the upper and lower ends of the liquid-guiding cloth are often more serious, which will destroy the tightness of the two ends of the atomizer core liquid-guiding element 932 and the inner wall of the atomizer core shell 9324, which may cause air and liquid leakage of the atomizer core 930, and even make the entire atomization function invalid. Therefore, the minimum height of the tightly attached part of the atomizer core shell 9324 and the liquid-guiding element 932 above and below the shell liquid-guiding through hole 9325 is greater than 0.8 mm to effectively prevent external air from entering the liquid storage element 100 through the upper and lower edges of the atomizer core liquid-guiding element 932 and the tightly attached part of the atomizer core shell 9324.

<Liquid storage element>

In the aerosol bomb 800 of the present invention, the liquid storage element 100 is a component for storing the atomized liquid. Different liquids can be stored therein according to the purpose of application, such as electronic cigarette oil, CBD solution, drug solution, etc.

As shown in FIGS. 1 to 3 , the liquid storage element 100 has a liquid storage element through hole 130 that axially penetrates the liquid storage element 100. The liquid storage element through hole 130 can be used as an aerosol passage 1303 of the aerosol bomb 800. One end of the aerosol passage 1303 is an atomization module connection port 1302 that is connected to the atomization core 930, and the other end is an aerosol outlet 1301. The aerosol passage 1303 can be integrally formed with the liquid storage element 100, with the liquid storage element through hole 130 serving as the aerosol passage 1303, or it can be separately made of plastic, metal, etc. and assembled into the aerosol bomb 800.

In the present invention, the aerosol bomb 800 includes an aerosol bomb shell 810 and a second shell base 824 arranged at the bottom of the aerosol bomb shell 810, a first shell base 823 arranged inside the aerosol bomb shell 810 and spaced apart from the second shell base 824, and a buffer chamber 828 arranged between the first shell base 823 and the second shell base 824, and the independent air guide element 600 connects the liquid storage element 100 and the buffer chamber 828.

Specifically, in the present invention, as shown in Figures 1 to 3, preferably, the aerosol bomb housing 810 forms a cavity with an opening at the bottom, the top of the aerosol bomb housing 810 extends into the cavity to form a liquid storage element through hole 130, and the first housing base 823 is inserted into the cavity from the bottom of the aerosol bomb housing 810, and forms a liquid storage element 100 together with the aerosol bomb housing 810. An installation interval for installing the atomizer 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 also used as an aerosol channel 1303, and the upper part of the atomizer core 930 is tightly matched and sealed with the atomizer module connection port 1302 at the bottom of the aerosol channel 1303, and the lower part of the atomizer core 930 is tightly matched and sealed with the atomizer core assembly port 826 in the middle of the first housing base 823. The first housing base 823 is formed with an independent air guide element installation hole 660 that runs through the first housing base 823 for installing an independent air guide element 600. The second shell base 824 is spaced apart from the first shell base 823 to seal the bottom opening of the aerosol bomb shell 810 , and a buffer chamber 828 is formed between the first shell base 823 and the second shell base 824 . The independent air guide element 600 connects the liquid storage element 100 and the buffer chamber 828 .

Preferably, an elastomer (such as silicone) can be arranged between the upper part of the atomizer core 930 and the atomizer module connecting port 1302 at the lower part of the aerosol channel 1303, and between the lower part of the atomizer core 930 and the atomizer core assembly port 826, to increase the sealing effect between the atomizer core 930 and the atomizer module connecting port 1302 and the atomizer core assembly port 826, thereby preventing external air from leaking into the liquid storage element 100 through the installation part of the atomizer 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 Figure 1, the independent air guide element 600 is installed on the first shell base 823 and extends into the buffer chamber 828. Preferably, the depth of the independent air guide element 600 extending into the buffer chamber 828 exceeds 50% of the depth of the buffer chamber 828. More preferably, the depth of the independent air guide element 600 extending into the buffer chamber 828 exceeds 80% of the depth of the buffer chamber 828. Most preferably, the independent air guide element 600 extends into the buffer chamber 828 and approaches the second shell base 824.

As shown in FIG. 1 , in the present embodiment, the aerosol bomb 800 includes an isolation tube 829 that is connected to the base through hole 1122 of the aerosol bomb 800 and extends to the atomization core 930. One end of the isolation tube 829 is connected to the second shell base 824, and the other end of the isolation tube 829 is close to the atomization core 930. The top wall or side wall of the isolation tube 829 is close to the atomization core 930. The position is provided with an air guide hole 827 that connects the buffer chamber 828. Preferably, the isolation tube 829 is made of silicone. Preferably, the isolation tube 829 is connected to the atomization core 930 (not shown), that is, there is no spaced connection state between the isolation tube 829 and the atomization core 930, and the side wall of the isolation tube 829 is close to the atomization core 930. The position is provided with an air guide hole 827 that connects the buffer chamber 828. Preferably, the air guide hole 827 is composed of a plurality of small holes that can guide air but the atomized liquid is difficult to pass through. When atomized liquid leaks out of 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 bomb 800 through the base through hole 1122 or the aerosol channel 1303 .

In this embodiment, the aerosol bomb 800 includes a buffer chamber 828 connected to the atmosphere and an isolation tube 829 connected to the base through hole 1122 and the atomizing core 930. The independent air guide element 600 is arranged on the first shell base 823, 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 shell base 823 and the second shell base 824. The liquid storage element 100 is connected to the buffer chamber 828 between the first shell base 823 and the second shell base 824 through the independent air guide element 600, and is connected to the external atmosphere through the air guide hole 827 of the isolation tube 829, the isolation tube 829 and the base through hole 1122. The 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 shell base 823 and the second shell base 824, and the independent air guide element 600, thereby realizing the connection of the liquid storage element 100 and the 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 and the through hole 630 of the independent air guide element is sealed with liquid. The atomizing core liquid guide element 932 absorbs the liquid in the liquid storage element 100. The negative pressure in the liquid storage element 100 increases until it reaches a balanced state, and the liquid content of the atomizing core liquid guide element 932 reaches a certain level.

<Atomizer Core>

As shown in FIG. 4 , in this embodiment, the atomizer core 930 includes a tubular atomizer core housing 9324, a tubular atomizer core liquid guide element 932 tightly attached to the inner circumferential wall of the atomizer core housing 9324, an atomizer core liquid guide element through hole 932 b axially penetrating the atomizer core liquid guide element 932, and a heating element 931 attached to the inner circumferential wall of the atomizer core liquid guide element 932.

The atomizer core housing 9324 is provided with a housing liquid conducting through hole 9325 . The atomizer core liquid conducting through hole 9325 blocks the housing liquid conducting through hole 9325 and contacts the atomized liquid in the liquid storage element 100 through the housing liquid conducting through hole 9325 .

The atomizing core liquid guiding element through hole 932b forms an atomizing chamber 934 at the location where the heating element 931 is provided. The shell liquid guiding through hole 9325 of the atomizing core 930 can be hollowed out on the atomizing core shell 9324.

To further reduce the risk of air and liquid leakage of the atomizer core 930, OL1 is preferably greater than 1.2mm, 1.5mm or 1.8mm, and OL2 is preferably greater than 1.2mm, 1.5mm or 1.8mm. When OL1 and OL2 are greater than 1.2mm, in addition to effectively preventing external air from entering the liquid storage component 100 through the upper and lower edges of the atomizer core liquid guide element 932 and the atomizer core shell 9324 that are closely attached during normal use, it can also effectively prevent air and liquid leakage of the atomizer core 930 during storage and transportation, even if it encounters adverse environments such as high and low temperatures, low pressure, vibration, etc.

The atomizer core liquid guiding element 932 may include two or more layers (including two layers) of liquid guiding cloth.

The atomizer core liquid guide element 932 is closely attached to the inner peripheral wall of the atomizer core housing 9324. The atomizer core liquid guide element 932 is closely attached to the inner peripheral wall of the atomizer core housing 9324, which can prevent external air from entering the liquid storage element 100 through the atomizer core 930.

When the liquid-conducting cloth used is relatively soft, two or more layers (including two layers) of liquid-conducting cloth are used. As the number of layers of the liquid-conducting cloth increases, the strength of the atomizer core liquid-conducting element 932 will increase, and the effect of closely adhering to the inner circumferential wall of the atomizer core shell 9324 and effectively blocking the shell liquid-conducting through hole 9325 will also increase.

Preferably, the atomizer core liquid guide element 932 includes 4 to 7 layers of liquid guide cloth. When the liquid guide cloth is greater than or equal to 4 layers and less than or equal to 7 layers, it can ensure that the inner circumferential wall of the atomizer core shell 9324 is closely adhered to and the liquid guide through hole 9325 of the shell is effectively blocked, and at the same time, the speed at which the liquid penetrates from the liquid storage element 100 through the liquid guide cloth to the heating element 931 can be ensured, so as to achieve a high-quality atomization effect.

The liquid-conducting cloth is preferably made of fibers that can withstand relatively high temperatures, such as spunlace cloth, needle-punched cloth, woven cloth, etc. made of cotton fiber, viscose fiber, linen fiber or carbon fiber. Preferably, linen fiber is used to cover the heating element 931.

At least one layer of liquid-conducting cloth includes textures, and the textures include micro-ridges and/or micro-grooves. The micro-ridges and/or micro-grooves on the liquid-conducting cloth are conducive to forming a micro space for storing atomized liquid when multiple layers of liquid-conducting cloth overlap each other, thereby reducing the probability of the liquid-conducting element 932 of the atomizing core lacking liquid during atomization. The texture direction of the liquid-conducting cloth refers to the overall extension direction of the micro-ridges and/or micro-grooves on the liquid-conducting cloth on the liquid-conducting cloth. For example, the texture on the liquid-conducting cloth extends radially or axially along the atomizing core 930, but it is not required that each texture extends strictly radially or axially along the atomizing core 930. It can also be a branch texture that extends partially in other directions on the basis of the texture extending radially or axially.

The texture on the liquid-guiding fabric is usually produced during the production or post-processing of the liquid-guiding fabric. The height of the micro-ridges and the depth of the micro-grooves usually do not exceed one hundred microns. For example, spunlace fabric usually produces overall texture along the machine direction (MD) during production. However, some arrangements of water needle holes can be designed on the water needle plate used to produce spunlace fabric, so that the overall texture of the spunlace fabric along the machine direction can extend into some branch textures in other directions.

When the liquid-guiding cloths are attached to each other, or when the liquid-guiding cloths are attached to the inner wall of the atomizer core shell 9324, the overall extension direction of the lines on the liquid-guiding cloths makes the formed micro-grooves and micro-ridges become channels that are conducive to the flow of liquid.

In the present invention, it is preferred that the texture direction of the liquid-guiding cloth attached to the inner circumferential wall of the atomizer core housing 9324 is along the radial direction of the atomizer core 930. Thus, when the atomized liquid contacts the liquid-guiding cloth closely attached to the inner wall of the atomizer core housing 9324 through the housing liquid-guiding through hole 9325 of the atomizer core housing 9324, it is beneficial for the liquid to flow radially along the atomizer core 930 on the liquid-guiding cloth. Moreover, when the liquid-guiding element is closely attached to the inner circumferential wall of the atomizer core housing 9324 and is infiltrated by the atomized liquid, the micro-ridges and/or micro-grooves distributed radially along the atomizer core 930 play a role in blocking external gas from entering the liquid storage element 100 through the gap between the atomizer core housing 9324 and the liquid-guiding cloth, and thus, it can effectively block external air from entering the liquid storage element 100 through the atomizer core 930. Therefore, during the normal use of the aerosol bomb 800, external air can only enter the liquid storage element 100 through the independent air guide element 600, thereby improving the negative pressure in the liquid storage element 100 and the atomization stability.

In this embodiment, preferably, the direction of the lines of the liquid-guiding cloth in contact with the heating element 931 is along the axial direction of the atomizer core 930. The direction of the lines of the liquid-guiding cloth in contact with the heating element 931 is substantially consistent with the partial lines of the heating element 931, which is beneficial to the flow and conduction of the liquid between the layer of liquid-guiding cloth and the heating element 931.

In this embodiment, the atomizer core liquid guiding element 932 preferably includes at least two layers of liquid guiding cloth with inconsistent grain directions, and more preferably, the atomizer core liquid guiding element 932 includes at least one layer of liquid guiding cloth with grain directions along the axial direction of the atomizer core 930 and at least one layer of liquid guiding cloth with grain directions along the radial direction of the atomizer core 930. This configuration is conducive to the liquid flowing in the atomizer core liquid guiding element 932 along the radial and axial directions of the atomizer core 930 at the same time, increasing the liquid supply speed of the atomizer core 930 and reducing the possibility of the atomizer core liquid guiding element 932 lacking liquid during rapid atomization.

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

Since the atomizer core 930 according to the present invention cannot replenish gas into the liquid storage element 100 under normal working conditions, the atomizer core 930 according to the present invention cannot smoothly atomize liquid when used alone in the aerosol dispensing device 1 in the absence of the independent gas guide element 600. If the independent gas guide element 600 is missing, as the atomization proceeds, the negative pressure inside the liquid storage element 100 will continue to increase, resulting in insufficient liquid supply to the atomizer core liquid guide element 932 and burning the atomizer core 930.

As shown in FIG4 , in the present invention, the atomizer core 930 further includes an atomizer core base 935 and a wire 933 connected to the heating element 931, and the wire 933 is fixed on the atomizer core base 935. Preferably, the atomizer core base 935 is disposed in the atomizer core housing 9324 and below the atomizer core liquid guide element 932.

An aerosol bomb electrode 936 can be set on the aerosol bomb 800, and one end of the aerosol bomb electrode 936 is connected to the wire 933 by welding, riveting or crimping, and the other end of the aerosol bomb electrode 936 is connected to the host electrode 954 in the aerosol dispensing device 1 by plugging, spring clip crimping or magnetic contact.

When the aerosol bomb electrode 936 is electrically connected to the outside by means of spring sheet crimping or plugging, it is preferred that the aerosol bomb electrode 936 is columnar, and the columnar aerosol bomb electrode 936 can be made by cutting metal wire. Such an aerosol bomb electrode 936 does not need to be specially processed to form a large contact area, which can significantly reduce the production cost of the aerosol bomb electrode 936. In order to make it easy for the aerosol bomb electrode 936 to be inserted into the external plug hole for electrical connection, the end face of the columnar aerosol bomb electrode 936 can be chamfered.

In the present invention, the aerosol bomb 800 also includes an atomizing core reinforcing core 9326, which axially passes through the atomizing core liquid guide element through hole 932b and is covered by the atomizing core liquid guide element 932 and the heating element 931. After the aerosol bomb is injected with liquid, the atomizing core reinforcing core can enhance the strength of the atomizing core liquid guide element 932 and its tightness against the inner wall of the atomizing shell. During the storage and transportation of the product, the atomizing core reinforcing core 9326 can prevent the atomizing core liquid guide element 932 and the heating element 931 from being deformed or loosened, so that the performance of the aerosol bomb 800 remains stable.

<Independent air guide element>

Figure 5 is a first cross-sectional schematic diagram of an independent air guiding element according to the first embodiment of the present invention; Figure 6 is a second cross-sectional schematic diagram of an independent air guiding element according to the first embodiment of the present invention; Figure 7 is a third cross-sectional schematic diagram of an independent air guiding element according to the first embodiment of the present invention; Figure 8 is a fourth cross-sectional schematic diagram of an independent air guiding element according to the first embodiment of the present invention.

As shown in FIG. 1 , in the present invention, the independent air guide element 600 is independent of the atomizer core liquid guide element 932, that is, the atomizer core liquid guide element 932 does not participate in forming the peripheral wall of the independent air guide element through hole 630. Different from the air guide channel formed by the liquid guide channel in the prior art, the atomizer core liquid guide element 932 in the present invention does not participate in forming the air guide channel of the independent air guide element 600, and the independent air guide element 600 does not participate in providing liquid to the atomizer core 930.

In the aerosol bomb 800 , one or more independent air guide elements 600 may be provided.

As shown in Figures 5 to 8, in the present invention, 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 independent air guide element through hole 630 is used as the only air guide channel of the aerosol bomb 800.

The independent air guide element 600 may further include an independent air guide element cover 650 disposed on the outer periphery of the independent air guide element core 640 for mounting the independent air guide element core 640 .

As shown in Figure 5, the independent air guiding element through hole 630 can be set in the independent air guiding element core 640; or as shown in Figure 6, a plurality of notches are formed on the outer peripheral wall of the independent air guiding element core 640, thereby forming an independent air guiding element through hole 630 between the independent air guiding element core 640 and the independent air guiding element jacket 650; or as shown in Figure 7, the independent air guiding element core 640 is embedded in an independent air guiding element jacket 650 having reinforcing ribs, thereby forming an independent air guiding element through hole 630 between the independent air guiding element core 640 and the independent air guiding element jacket 650; or as shown in Figure 8, there is a gap between the independent air guiding element core 640 and the independent air guiding element jacket 650, thereby forming an independent air guiding element through hole 630 between the independent air guiding element core 640 and the independent air guiding element jacket 650.

In this embodiment, the independent air guide element core 640 can be made of non-porous materials such as plastic or metal. The independent air guide element 600 can also be made of sintered plastic powder.

In this embodiment, the independent air-conducting element core 640 may also be a porous material. Preferably, the independent air-conducting element core 640 is made of fibers bonded together. Since liquid penetrates quickly into the bonded fibers, it is beneficial to improve the sensitivity of the independent air-conducting element 600. More preferably, the independent air-conducting element core 640 is made of fibers bonded together in a skin-core structure. Such fibers do not require adhesives and can be bonded and formed by heating, thereby reducing the risk of harmful substances.

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

The maximum inscribed circle diameter of the minimum cross section of the independent air guide element through hole 630 is 0.1 mm to 1.5 mm, such as 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.2 mm, 1.5 mm, etc. When the viscosity of the atomized liquid is small or the required atomization amount is small, a smaller independent air guide element through hole 630 can be set; when the viscosity of the atomized liquid is large or the required atomization amount is large, a larger independent air guide element through hole 630 can be set. The cross section of the independent air guide element through hole 630 can be set to various geometric shapes, such as circular, sector-shaped, annular, polygonal, etc.

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

<Aerosol bomb>

In the present invention, the aerosol bomb 800 includes a detachable liquid storage module and an atomization module. The liquid storage module at least includes a liquid storage element 100, and the atomization module at least includes an atomization core 930. The liquid storage module and the atomization module can be plugged together to form the aerosol bomb 800.

Specifically, as shown in Figure 2, the liquid storage module can be a module integrated with the aerosol bomb shell 810 and the first shell base 823, and the atomization module can be a module integrated with the atomization core 930 and the second shell base 824. Structures that can be plugged into each other are respectively provided on the liquid storage module and the atomization module, thereby simply completing the assembly of the aerosol bomb 800 and facilitating the replacement of the liquid storage element 100.

Fig. 9 is a schematic diagram of the structure of another aerosol bomb according to the first embodiment of the present invention. As shown in Fig. 9, in this embodiment, the aerosol bomb 800 further includes an aerosol channel 1303 and a condensate absorption element 400 disposed in the aerosol channel 1303. The condensate absorption element 400 is used to absorb the condensate that may be generated in the aerosol, which can enhance the experience of users who prefer dry smoke.

As shown in FIG9 , when the independent air guide element core 640 is made of non-porous materials such as plastic or metal, preferably, a porous material pad 843 is provided at the lower end of the independent air guide element 600 to abut against the independent air guide element 600. The porous material pad 843 can be made of fiber bonding and has a density of less than 0.1 g/cm ³ . When the atomized liquid leaks from the through hole 630 of the independent air guide element under abnormal conditions, the liquid is preferentially absorbed by the porous material pad 843. When the environment returns to normal, part of the liquid in the porous material pad 843 can return to the liquid storage element 100 through the through hole 630 of the independent air guide element. When the liquid in the liquid storage element 100 is consumed by atomization, the external air can penetrate the porous material pad 843 to enter the through hole 630 of the independent air guide element and replenish the liquid storage element 400.

Preferably, the porous material pad 843 is disposed at the bottom of the buffer chamber 828. When the liquid in the liquid storage element 100 leaks into the buffer chamber 828 under normal conditions, the porous material pad 843 can absorb the leaked liquid and can return the leaked liquid to the liquid storage element 100 through the independent gas guide element 600.

Preferably, the independent air guide element 600 and the first shell base 823 are integrally formed.

Second embodiment

Fig. 10 is a schematic diagram of the structure of an aerosol bomb according to a second embodiment of the present invention. This embodiment is similar in structure to the first embodiment, and the same parts as the first embodiment will not be repeated in the description of this embodiment.

The difference between this embodiment and the first embodiment lies in that, according to the aerosol bomb 800 of the second embodiment, an aerosol bomb electrode 936 is provided, and the aerosol bomb electrode 936 is installed at the bottom of the second shell base 824, one end of the aerosol bomb electrode 936 is connected to the wire 933 of the atomization core 930, and the other end of the aerosol bomb electrode 936 is electrically connected to the host electrode 954 in the aerosol dispensing device 1, and preferably the two are connected by magnetic attraction.

The aerosol bomb 800 according to the present embodiment can be detachably installed in the aerosol dispensing device 1 , so that the aerosol bomb 800 in the aerosol dispensing device 1 can be easily replaced.

In addition, in this embodiment, an aerosol bomb with a liquid injection port is also provided. The liquid injection port 841 can be provided on the liquid storage element 100 of any aerosol bomb 800 of the present invention. Preferably, the liquid injection port 841 is provided on the side wall of the liquid storage element 100 to facilitate the injection of atomized liquid during the assembly or use of the aerosol bomb 800. The liquid injection port 841 is sealed by a liquid injection port sealing element 842.

When the aerosol bomb 800 is provided with a liquid injection port 841 , the number of independent gas guide elements 600 is preferably one.

When there is one independent gas-guiding element, the injection port 841 is set at a position close to the independent gas-guiding element on the liquid storage element 100. In the present invention, the position close to the independent gas-guiding element has a special meaning, which refers to the position of the injection port 841 on the liquid storage element 100 that makes the independent gas-guiding element 600 contact the liquid the latest during liquid injection. For example, when the liquid storage element 100 is a rectangular parallelepiped, the side surface close to the independent gas-guiding element 600 can be regarded as the position close to the independent gas-guiding element. When the liquid storage element 100 is a cylinder, the position where the center of the injection port 841 is located on the busbar with the shortest distance from the central axis of the independent gas-guiding element 600 is regarded as the position close to the independent gas-guiding element.

When the aerosol bomb 800 is provided with a liquid injection port 841, according to the aerosol bomb 800 of the present invention, since the atomizer core liquid guide element 932 is tightly attached to the inner circumferential wall of the atomizer core shell 9324, and the minimum height OL1 of the tightly attached portion of the atomizer core shell 9324 and the liquid guide element 932 above the shell liquid guide through hole 9325 is greater than 0.8 mm, and the minimum height OL2 of the tightly attached portion of the atomizer core shell 9324 and the liquid guide element 932 below the shell liquid guide through hole 9325 is greater than 0.8 mm, liquid can be effectively prevented from leaking from the atomizer core 930 during liquid injection.

When the liquid injection port 841 is set near the position of the independent gas guide element on the side wall of the liquid storage element 100, the independent gas guide element 600 will not contact the liquid until the liquid injection is nearly completed. Therefore, it can effectively prevent the liquid from leaking from the independent gas guide element 600 during the liquid injection.

As shown in FIG10 , the aerosol bomb 800 according to the second embodiment of the present invention includes an atomizing core reinforcing core 9326 . The atomizing core reinforcing core 9326 axially passes through the atomizing core liquid guiding element through hole 932 b and is covered by the atomizing core liquid guiding element 932 and the heating element 931 .

After the aerosol bomb is injected with liquid, the atomizer core liquid guide element 932 absorbs the liquid. In the absence of the atomizer core reinforcing core 9326, the atomizer core liquid guide element 932 will swell and deform, and the swelling and deformation of the two ends of the atomizer core liquid guide element 932 are often more serious, which may destroy the tightness of the two ends of the atomizer core liquid guide element 932 and the inner wall of the atomizer core shell 9324, causing the atomizer core to leak air and liquid, and even make the entire atomization function invalid. When the aerosol bomb includes the atomizer core reinforcing core 9326, subject to the space limitation between the atomizer core shell 9324 and the atomizer core reinforcing core 9326, after the aerosol bomb is injected with liquid, the atomizer core liquid guide element 932 absorbs the liquid, and the fibers in the atomizer core liquid guide element 932 absorb the liquid and swell and squeeze each other, so that the strength of the atomizer core liquid guide element 932 is improved, and the adhesion between it and the atomizer core shell 9324 is tighter, further enhancing the effectiveness of the entire atomization system. Thanks to the relaxation property of the polymer chain, after a period of time, even if the atomizer core reinforcing core 9326 is pulled out, the atomizer core liquid guide element 932 will not be significantly deformed, thereby eliminating the risk of leakage of the aerosol cartridge or failure of the atomization system.

In addition, during the storage and transportation of the product, the atomizer core reinforcement core 9326 can effectively prevent the atomizer core liquid guide element 932 and the heating element 931 from being deformed or loosened, so that the performance of the aerosol bomb 800 remains stable.

When in use, just unplug the atomizing core reinforcing core 9326.

FIG11 is a schematic diagram of the structure of the aerosol bomb according to the third embodiment of the present invention; FIG12 is a schematic diagram of the cross-sectional structure of the atomizer core according to the third embodiment of the present invention; FIG13 is a schematic diagram of the cross-sectional structure of the independent air guide element according to the third embodiment of the present invention. This embodiment is similar in structure to the first embodiment, and the same parts as the first embodiment will not be repeated in the description of this embodiment. The difference is that,

As shown in FIGS. 11 to 13 , the atomizer core 930 of the aerosol bomb 80 according to the third embodiment of the present invention, the liquid storage element 100 for supplying liquid to the atomizer core 930, and the independent air guide element 600 for connecting the liquid storage element 100 and the external atmosphere; the atomizer core 930 includes a tubular atomizer core shell 9324, a tubular atomizer core liquid guide element 932 tightly attached to the inner circumferential wall of the atomizer core shell 9324, an atomizer core liquid guide element through hole 932b axially penetrating the atomizer core liquid guide element 932, and a heating element 931 attached to the inner circumferential wall of the atomizer core liquid guide element 932; a shell liquid guide through hole 9325 is provided on the atomizer core shell 9324, and the atomizer core liquid guide element 932 blocks the shell liquid guide through hole 9325 and contacts with the atomized liquid in the liquid storage element 100 through the shell liquid guide through hole 9325; the shell liquid guide through hole 9325 is above the atomizer core shell The minimum height OL1 of the part where the atomizer core shell 9324 and the liquid guiding element 932 are tightly attached is greater than 0.8 mm, and the minimum height OL2 of the part where the atomizer core shell 9324 and the liquid guiding element 932 are tightly attached below the shell liquid guiding through hole 9325 is greater than 0.8 mm; the aerosol bomb 800 also includes an aerosol bomb shell 810 and a second shell base 824 arranged at the bottom of the aerosol bomb shell 810, a first shell base 823 arranged inside the aerosol bomb shell 810 and spaced from the second shell base 824, and a buffer chamber 828 arranged between the first shell base 823 and the second shell base 824, and the independent gas guiding 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 independent air guide element core 640 includes a porous material treated with organic fluorine or organic silicon, such as bonding fiber, sponge, or film. Since the contact angle of the independent air guide element core 640 to the atomized liquid is greater than 90°, when the aerosol bomb 800 is working, external air can be replenished from the independent air guide element 600 through the buffer chamber 828 to enter the liquid storage element 100, but the atomized liquid cannot be guided 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 cover 650. The independent air guide element 600 may be directly assembled in the independent air guide element installation hole 660 provided on the first housing base 823.

The aerosol bomb 800 according to the third embodiment of the present invention further comprises a buffer liquid guiding element 670. In the present invention, the buffer liquid guiding element 670 can only guide liquid but not gas during normal use, and the buffer liquid guiding element 670 connects the liquid storage element 100 and the buffer chamber 828.

In the aerosol bomb 800 according to the third embodiment of the present invention, the independent air guide element 600 and the buffer liquid guide element 670 are connected to the liquid storage element 100 and the buffer chamber 828. Under abnormal conditions, the liquid in the liquid storage element 100 is led out from the buffer liquid guide element 670 and temporarily stored in the buffer chamber 828, and the isolation tube 829 connected to 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 liquid temporarily stored in the buffer chamber 828 returns to the liquid storage element 100 through the buffer liquid guide element 670, avoiding the waste of atomized liquid, while reducing the risk of liquid leakage to the outside of the aerosol bomb 800 during storage and use.

In this embodiment, as shown in FIG. 11 , the first housing base 823 further includes two electrode insertion holes 8231 disposed adjacent to the atomizer core base 935 , and the wires 933 fixed by the atomizer core base 935 extend into the electrode insertion holes 8231 .

As shown in FIG. 11 , one end of the two aerosol bomb electrodes 936 passes through the second housing base 824 and is inserted into the electrode plug hole 8231 to be electrically connected to the wire 933 .

Fourth embodiment

Fig. 14 is a schematic diagram of the structure of the aerosol bomb according to the fourth embodiment of the present invention; Fig. 15 is a schematic cross-sectional diagram of the independent air guide element according to the fourth embodiment of the present invention. This embodiment is similar in structure to the first embodiment, and the same parts as the first embodiment are not repeated in the description of this embodiment.

As shown in FIGS. 14 and 15 , the mist bomb 80 according to the fourth embodiment of the present invention comprises an atomizing core 930, a liquid storage element 100 for supplying liquid to the atomizing core 930, and an independent air guide element 600 for connecting the liquid storage element 100 and the external atmosphere; the atomizing core 930 comprises a tubular atomizing core shell 9324, a tubular atomizing core liquid guide element 932 tightly attached to the inner circumferential wall of the atomizing core shell 9324, an atomizing core liquid guide element through hole 932b axially penetrating the atomizing core liquid guide element 932, and a heating element 931 attached to the inner circumferential wall of the atomizing core liquid guide element 932; a shell liquid guide through hole 9325 is provided on the atomizing core shell 9324, the atomizing core liquid guide element 932 blocks the shell liquid guide through hole 9325, and is connected to the liquid storage element 100 through the shell liquid guide through hole 9325. 0; the minimum height OL1 of the atomizer core shell 9324 above the shell liquid guide hole 9325 and the liquid guide element 932 tightly covered part is greater than 0.8mm, and the minimum height OL2 of the atomizer core shell 9324 below the shell liquid guide hole 9325 and the liquid guide element 932 tightly covered part is greater than 0.8mm; the aerosol bomb 800 also includes an aerosol bomb shell 810 and a second shell base 824 arranged at the bottom of the aerosol bomb shell 810, a first shell base 823 arranged inside the aerosol bomb shell 810 and spaced from the second shell base 824, and a buffer chamber 828 arranged between the first shell base 823 and the second shell base 824, and the independent gas 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 less than 90°. The independent air guide element core 640 is a porous material having a contact angle with the atomized liquid of less than 90° and not having an independent air guide element through hole 630. When the atomized liquid in the aerosol bomb is consumed, the negative pressure in the liquid storage element increases, and the liquid in the independent air guide element 600 is partially sucked back into the liquid storage element. 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 gas-conducting element 600 includes a high capillary porosity body 601 and a low capillary porosity body 602. When the liquid in the independent gas-conducting element 600 is sucked back into the liquid storage element, due to the difference in capillary forces between the two, the high capillary porosity body 601 can absorb liquid from the low capillary porosity body 602, thereby causing the low capillary porosity body 602 to lose more liquid and produce better gas-conducting ability, and external air can be replenished into the liquid storage element 100 through the low capillary porosity body 602.

Fifth embodiment

Figure 16 is a schematic diagram of the structure of the first aerosol dispersing device according to the fifth embodiment of the present invention; Figure 17 is a schematic diagram of the structure of the second aerosol dispersing device according to the fifth embodiment of the present invention; Figure 18 is a schematic diagram of the structure of the third aerosol dispersing device according to the fifth embodiment of the present invention; Figure 19 is a schematic diagram of the structure of the fourth aerosol dispersing device according to the fifth embodiment of the present invention; Figure 20 is a schematic diagram of the structure of the fifth aerosol dispersing device according to the fifth embodiment of the present invention; Figure 21 is a schematic diagram of the structure of the sixth aerosol dispersing device according to the fifth embodiment of the present invention; Figure 22 is a schematic diagram of the structure of the seventh aerosol dispersing device according to the fifth embodiment of the present invention.

The aerosol dispensing device 1 according to the fifth embodiment of the present invention includes any one of the above-mentioned aerosol bombs 800 .

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

As shown in FIG16 , in the first aerosol dispensing device 1 according to the fifth embodiment of the present invention, the wire 933 of the aerosol bomb 800 extends into the host housing 950 and is welded to the host control circuit 956. The aerosol bomb 800 is inserted into the host housing 950 and is tightly sealed with the host housing 950.

As shown in FIG17 , the second aerosol dispensing device according to the fifth embodiment of the present invention is similar in structure to the first aerosol dispensing device according to the fifth embodiment of the present invention, except that the second aerosol dispensing device 1 according to the fifth embodiment of the present invention further includes an aerosol outlet sealing element 1306 and a main engine air inlet sealing element 957. The aerosol outlet sealing element 1306 is used to seal the aerosol outlet 1301 of the aerosol bomb 800, and the main engine air inlet sealing element 957 is used to seal the air inlet of the aerosol dispensing device 1.

By providing the aerosol outlet sealing element 1306 and the main unit air inlet sealing element 957 , it is possible to prevent the aerosol dispensing device 1 from leaking during storage and transportation.

When in use, the aerosol outlet sealing element 1306 and the main engine air inlet sealing element 957 of the aerosol dispensing device 1 are unplugged, and the liquid on the atomizing core liquid guiding element 932 is heated and atomized, and the aerosol generated in the atomizing chamber 934 escapes through the aerosol channel 1303. The atomizing core liquid guiding element 932 absorbs liquid from the liquid storage element 100 and replenishes it around the heating element 931. As the liquid is led out, the negative pressure in the liquid storage element 100 increases, and the liquid in the independent air guiding element 600 gradually returns to the liquid storage element 100 until the liquid seal of the independent air guiding element through hole 630 is opened. External air enters the liquid storage element 100 through the independent air guiding element through hole 630, causing the negative pressure in the liquid storage element 100 to drop, and the independent air guiding element through hole 630 is sealed again. This process is repeated so that the atomization process can be continuously carried out until the liquid in the liquid storage element 100 is used up.

Under abnormal conditions, such as when the external pressure drops or the temperature rises, the negative pressure in the liquid storage element 100 decreases, and the liquid is discharged from the independent air guide element 600 and temporarily stored in the buffer chamber 828, thereby preventing the liquid from leaking from the aerosol bomb 800. When the external pressure or temperature returns to normal, the liquid temporarily stored in the buffer chamber 828 returns to the liquid storage element 100 through the independent air guide element 600.

As shown in FIG17 , the second aerosol dispensing device 1 according to the fifth embodiment of the present invention may further include an atomizer core reinforcing core 9326. The atomizer core reinforcing core 9326 axially passes through the atomizer core liquid guide element through hole 932b and is covered by the atomizer core liquid guide element 932 and the heating element 931.
