[0029] First embodiment

[0030] In the aerosol bomb of the present invention, as Figure 1 shown, the aerosol bomb of this embodiment includes a liquid storage element 100, an atomization core 930, and a gas-liquid exchange element 290 that connects the liquid storage element 100 and the atomization core 930. The atomization core 930 includes an atomization core liquid guiding element 932 and a mesh heating element 931. The gas-liquid exchange element 290 includes a gas-liquid exchange element sleeve 2905, a gas-liquid exchange element core 2901 inserted into the gas-liquid exchange element sleeve 2905, and a gas-liquid exchange element through hole 2903 that axially penetrates the gas-liquid exchange element 290. The mesh heating element 931 is a grid-shaped heating element formed by punching holes in a sheet-shaped resistive material.

[0031] According to the atomization device (not shown) of the present embodiment, it includes the aerosol cartridge 800 in any one of the embodiments of the present invention. The atomization device can be a general atomization device in the art and can be docked and assembled with the aerosol cartridge 800 of the present invention through conventional techniques in the art. In the present invention, when the atomization device installed with the aerosol cartridge 800 works, the liquid is supplemented from the liquid storage element 100 to the atomization core liquid guiding element 932 through the gas-liquid exchange element 290 and is transported to the mesh heating element 931 through the atomization core liquid guiding element 932. Since the mesh heating element 931 is not formed by weaving or winding a resistance wire, but is a grid-shaped heating element formed by punching holes in a whole sheet of sheet resistance material, no contact resistance will be generated at the intersection of the resistance wires, making the resistance value of the atomization core more stable and the atomization control of the liquid more accurate.

[0032] In the present embodiment, the bottom of the aerosol cartridge 800 may further include a support element 500. The support element 500 can be used to support the atomization core 930 and can also be used to seal the lower opening of the lower part of the aerosol cartridge 800. The support element 500 may include an air inlet 1121 formed by a through hole penetrating the support element 500. The air inlet 1121 is preferably located directly below the mesh heating element 931.

[0033] Preferably, an aerosol channel 1303 is formed directly above the mesh heating element 931. During operation, the air flow entering from the air inlet 1121 blows the mesh heating element 931 of the atomization core 930, and the generated aerosol escapes from the aerosol outlet through the aerosol channel 1303.

[0034] In the present embodiment, one end of the through hole 2903 of the gas-liquid exchange element is blocked by the atomization core 930. Preferably, one end of the through hole 2903 of the gas-liquid exchange element is blocked by the atomization core liquid guiding element 932.

[0035] Since the end of the gas-liquid exchange element 290 in contact with the atomizer core 930 is blocked by the atomizer core 930, the outside air passes through the atomizer core 930 and enters the liquid storage element 100 through the gas-liquid exchange element 290, thereby maintaining the pressure in the liquid storage element 100 stable and making the atomization process stable. When the external environment changes, such as the ambient temperature rises, the pressure in the liquid storage element 100 increases, and the liquid in the liquid storage element 100 is guided out of the gas-liquid exchange element 290 and transferred to the periphery of the atomizer core 930 by the atomizer core liquid guide element 932 for temporary storage, so as to prevent the liquid from leaking from the aerosol bomb 800 to the outside. When the ambient temperature drops, the pressure in the liquid storage element 100 drops, and since the end of the gas-liquid exchange element 290 in contact with the atomizer core 930 is blocked by the atomizer core 930, the liquid temporarily stored around the atomizer core 930 returns to the liquid storage element 100 through the atomizer core liquid guide element 932 and the gas-liquid exchange element 290. When the ambient temperature rises and falls repeatedly, the above process is repeated, thereby greatly reducing the risk of liquid leakage of the aerosol bomb 800 and releasing the liquid in the liquid storage element 100 as much as possible.

[0036] In the aerosol bomb 800 of the present invention, Figure 2 As shown, the gas-liquid exchange element through hole 2903 is arranged in the gas-liquid exchange element core 2901. Figure 3 As shown, the gas-liquid exchange element through hole 2903 is arranged between the gas-liquid exchange element core 2901 and the gas-liquid exchange element sleeve 2905.

[0037] The maximum inscribed circle diameter of the minimum cross-section of the gas-liquid exchange element through hole 2903 is 0.2 mm to 2.0 mm, such as 0.2 mm, 0.3 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm, and 2.0 mm.

[0038] Preferably, the gas-liquid exchange element core 2901 is a porous material, such as porous plastic, porous ceramic, porous metal, preferably a fiber-bonded porous material. Liquid conducts quickly in a fiber-bonded porous material, which is beneficial to improving the sensitivity of gas-liquid exchange.

[0039] like Figure 4 and Figure 5 As shown, the mesh heating element 931 includes a plurality of transverse resistance wires 9311 extending along a first direction and a plurality of connecting resistance wires 9312 extending along a second direction. The first direction is perpendicular to the second direction. The plurality of transverse resistance wires 9311 are spaced apart along the second direction. The connecting resistance wire 9312 is used to connect two adjacent transverse resistance wires 9311.

[0040] Preferably, the transverse resistance wire 9311 is in the shape of a broken line or a curve. Figure 4As shown, the mesh heating element 931 includes two zigzag-shaped lateral resistance wires 9311, and multiple connecting resistance wires 9312 that connect the zigzag-shaped lateral resistance wires 9311.

[0041] As Figure 5 shown, the mesh heating element 931 includes six zigzag-shaped lateral resistance wires 9311, and multiple connecting resistance wires 9312 that connect the zigzag-shaped lateral resistance wires 9311.

[0042] As Figure 6 shown, the mesh heating element 931 shown includes straight lateral resistance wires 9311 and straight connecting resistance wires 9312.

[0043] When manufacturing the mesh heating element 931, methods such as die cutting, etching, or laser drilling can be used. The mesh heating element 931 is an alloy containing two or more components of metals such as iron, chromium, nickel, titanium, and aluminum. Wires 933 can be welded to the mesh to facilitate the electrical connection between the atomization core 930 and the outside.

[0044] In the aerosol bomb 800 of the present invention, the mesh heating element 931 is bent and wrapped around the outer periphery of the atomization core liquid guiding element 932. Figure 4 Or Figure 6 The mesh heating element 931 shown is curled from left to right and wrapped around the outer periphery of the atomization core liquid guiding element 932, and the atomization core 930 as shown in Figure 7 can be formed. To increase the atomization efficiency, it is preferred that the mesh heating element 931 wraps around the outer periphery of the atomization core liquid guiding element 932 by no less than 180°, more preferably, the mesh heating element 931 wraps around the outer periphery of the atomization core liquid guiding element 932 by no less than 270°, and most preferably, the mesh heating element 931 wraps around the outer periphery of the atomization core liquid guiding element 932 by no less than 330°.

[0045] The mesh as Figure 5 shown is curled from top to bottom and wrapped around the outer periphery of the atomization core liquid guiding element 932, and the atomization core 930 as shown in Figure 8 can be formed.

[0046] In this embodiment, one end of the gas-liquid exchange element 290 is blocked by the atomization core 930, which is beneficial to form a negative pressure in the liquid storage element 100 and significantly reduces the liquid content in the liquid guiding element 932 of the atomization core. Since the mesh heating element 931 is coated on the outer periphery of the liquid guiding element 932 of the atomization core, the liquid in the liquid storage element 100 is transmitted to both ends of the liquid guiding element 932 of the atomization core through the gas-liquid exchange element 290, and then conducted to the contact part between the liquid guiding element 932 of the atomization core and the mesh heating element 931 and heated and evaporated. Therefore, in this invention, the liquid atomized under the same heating power and heating time is greatly reduced, so the aerosol particles are finer and the aerosol is drier, greatly reducing the sweetness caused by large particles of glycerol, which is very suitable for the electronic nicotine delivery system with tobacco flavor.

[0047] In the present invention, the liquid guiding element 932 of the atomization core may include one or more porous liquid guiding materials, such as sheet-like porous ceramics, or fiber bundles, non-woven fabrics, etc. made of materials such as ceramic fibers, cellulose fibers, glass fibers, and carbon fibers.

[0048] Second Embodiment

[0049] Figure 9 FIG. is a schematic structural diagram of an aerosol cartridge according to the second embodiment of the present invention; Figure 10 FIG. is a schematic structural diagram of another aerosol cartridge according to the second embodiment of the present invention. This embodiment is similar to the first embodiment, and the same parts as the first embodiment will not be described again.

[0050] As Figure 9 and Figure 10 shown, the aerosol cartridge 800 of this embodiment includes a liquid storage element 100, an atomization core 930, an aerosol channel 1303, and a gas-liquid exchange element 290 connecting the liquid storage element 100 and the atomization core 930. The atomization core 930 includes a liquid guiding element 932 of the atomization core and a mesh heating element 931. The gas-liquid exchange element 290 includes a gas-liquid exchange element sleeve 2905, a gas-liquid exchange element core 2901 inserted into the gas-liquid exchange element sleeve 2905, and a gas-liquid exchange element through hole 2903 axially penetrating the gas-liquid exchange element 290. One end of the gas-liquid exchange element through hole 2903 in contact with the atomization core 930 is blocked by the atomization core 930 or blocked by the liquid guiding element 932 of the atomization core.

[0051] In this embodiment, the mesh heating element 931 is attached to one side or both sides of the liquid guiding element 932 of the atomization core.

[0052] In the aerosol cartridge 800 of this embodiment, the heating element is attached to one or both sides of the atomizing core liquid guiding element 932. The atomizing core liquid guiding element 932 includes one or more porous liquid guiding materials, such as sheet-like porous ceramics, or fiber bundles, non-woven fabrics, etc. made of materials such as ceramic fibers, cellulose fibers, glass fiber, and carbon fiber. For example, a mesh heating element 931 is attached to one surface of the porous ceramic, and a non-woven fabric is attached to the other surface of the porous ceramic; or the mesh heating element 931 is attached to one side or both sides of the non-woven fabric.

[0053] As Figure 9 shown, the support element 500 may include an air inlet 1121 formed by a through hole penetrating the support element 500. The air inlet 1121 is preferably located directly below the mesh heating element 931. During operation, the air flow entering from the air inlet 1121 blows the lower surface of the mesh heating element 931 of the atomizing core 930, and the generated aerosol escapes from the aerosol outlet through the aerosol channel 1303.

[0054] As Figure 10 shown, the support element 500 may include an air inlet 1121 formed by a through hole penetrating the support element 500. The air inlet 1121 is preferably located on one side of the mesh heating element 931, and the aerosol channel 1303 is located on the other side of the mesh heating element 931. The aerosol channel 1303 is preferably parallel to the central axis of the liquid storage element 100 and also parallel to the central axis of the air inlet 1121. Preferably, the central axes of the aerosol channel 1303 and the air inlet 1121 are respectively located on both sides of the central axis of the liquid storage element 100. During operation, the air flow entering from the air inlet 1121 can blow the upper surface of the mesh heating element 931 of the atomizing core 930, and the generated aerosol escapes from the aerosol outlet through the aerosol channel 1303.

[0055] Since the liquid conduction mechanism is similar to that of the first embodiment, this embodiment can also generate delicate aerosol particles.

[0056] This embodiment uses a sheet-like mesh heating element 931 in combination with a sheet-like atomizing core liquid guiding element 932, such as a die-cut non-woven fabric sheet, which is more convenient to assemble and has a lower cost.

[0057] The working principles of the aerosol cartridge 800 and the atomizing device according to the second embodiment are the same as those of the first embodiment.

[0058] In summary, the aerosol bomb 800 of the present invention has a simple structure and good leak prevention performance. Compared with the prior art, the aerosol bomb of the present invention can generate an aerosol with finer particles and greatly eliminates the sweetness caused by large particle glycerol. Compared with the heating element formed by weaving resistance wires, the resistance value of the mesh heating element is more stable, which is beneficial to more precise control of the atomization system. The atomization device using the aerosol bomb 800 of the present invention is convenient to use and has stable atomization. The aerosol bomb 800 and the atomization device of the present invention are applicable to applications such as tobacco-flavored electronic nicotine delivery systems and atomization of drug solutions.
