Background Technology

[0002] The widely used method in the field of electronic atomization is to adsorb liquid into oil reservoir cotton, and then conduct the liquid in the oil reservoir cotton to the liquid guiding element of the atomizing core and atomize it.

[0003] This technology suffers from poor flavor due to a lack of precise control over e-liquid delivery; furthermore, the atomization volume decreases as the release process continues, and the liquid absorbed in the reservoir cotton cannot be completely released. Additionally, when using a mesh-shaped heating element, which is formed by weaving or winding resistance wires, contact resistance is generated at the intersections of the resistance wires, resulting in unstable resistance of the atomizer core. Utility Model Content

The gas-liquid exchange element includes a gas-liquid exchange element sleeve, a gas-liquid exchange element core inserted into the gas-liquid exchange element sleeve, and a gas-liquid exchange element through hole axially penetrating the gas-liquid exchange element. The mesh heating element is a mesh-shaped heating element formed by drilling holes in a sheet-like resistive material.

[0005] Furthermore, one end of the through hole of the gas-liquid exchange element is blocked by the atomizing core.

[0006] Furthermore, the maximum inscribed circle diameter of the minimum cross-section of the through hole of the gas-liquid exchange element is 0.2 mm to 2.0 mm.

[0007] Furthermore, the core of the gas-liquid exchange element is made of a porous material.

[0008] Furthermore, the mesh heating element includes multiple transverse resistance wires extending along a first direction and multiple connecting resistance wires extending along a second direction. The first direction is perpendicular to the second direction. The multiple transverse resistance wires are spaced apart along the second direction. The connecting resistance wires are used to connect two adjacent transverse resistance wires.

[0009] Furthermore, the transverse resistance wire is either zigzag or curved.

[0010] Furthermore, the mesh heating element is bent and wrapped around the outer periphery of the atomizing core liquid guiding element.

[0011] Furthermore, the atomizing core liquid guiding element includes one or more porous liquid guiding materials.

[0012] Furthermore, the mesh heating element is attached to one or both sides of the atomizing core liquid guiding element.

[0013] The present invention also provides an atomizing device, the atomizing device comprising the aerosol bullet described in any of the preceding claims.

[0014] The aerosol cartridge and atomizing device of this invention are suitable for atomizing various liquids, such as e-cigarette liquids, drug solutions, and liquids in electric mosquito coils or electric aromatherapy products. The aerosol cartridge and atomizing device of this invention feature a stable resistance in the atomizing core, enabling uniform control of liquid atomization, good leak-proof performance, strong burst force, and the ability to release as much liquid as possible from the storage element.

[0029] First Embodiment

[0030] In the aerosol canister of this invention, such as Figure 1 As shown, the aerosol bullet of this embodiment includes a liquid storage element 100, an atomizing core 930, and a gas-liquid exchange element 290 connecting the liquid storage element 100 and the atomizing core 930. The atomizing core 930 includes an atomizing 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 axially penetrating the gas-liquid exchange element 290. The mesh heating element 931 is a mesh-shaped heating element formed by drilling holes in a sheet-like resistive material.

[0031] The atomizing device according to this embodiment (not shown) includes an aerosol cartridge 800 in any embodiment of this embodiment. The atomizing device can be a general atomizing device in the art, and can be connected and assembled with the aerosol cartridge 800 of this utility model using conventional techniques in the art. In this utility model, when the atomizing device equipped with the aerosol cartridge 800 is working, liquid is replenished from the liquid storage element 100 through the gas-liquid exchange element 290 to the atomizing core liquid guiding element 932, and then transported through the atomizing core liquid guiding element 932 to the mesh heating element 931. Because the mesh heating element 931 is not formed by weaving or winding resistance wires, but by forming a mesh heating element by punching holes in a whole sheet of sheet resistance material, no contact resistance is generated at the intersection of resistance wires, making the resistance value of the atomizing core more stable and the atomization control of the liquid more accurate.

[0032] In this embodiment, the bottom of the aerosol cartridge 800 may further include a support element 500, which can be used to support the atomizing core 930 and to seal the lower opening 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, and the air inlet 1121 is preferably located directly below the mesh heating element 931.

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

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

[0035] Because the end of the gas-liquid exchange element 290 that contacts the atomizing core 930 is blocked by the atomizing core 930, outside air passes through the atomizing core 930 and then enters the liquid storage element 100 via the gas-liquid exchange element 290, thereby maintaining stable pressure within the liquid storage element 100 and ensuring stable atomization. When the external environment changes, such as when the ambient temperature rises, the pressure within the liquid storage element 100 increases, and the liquid in the liquid storage element 100 is drawn out from the gas-liquid exchange element 290 and transferred by the atomizing core liquid guiding element 932 to the area around the atomizing core 930 for temporary storage, preventing liquid leakage from the aerosol cartridge 800 to the outside. When the ambient temperature drops, the pressure within the liquid storage element 100 decreases. Because the end of the gas-liquid exchange element 290 that contacts the atomizing core 930 is blocked by the atomizing core 930, the liquid temporarily stored around the atomizing core 930 returns to the liquid storage element 100 via the atomizing core liquid guiding element 932 and the gas-liquid exchange element 290. The above process is repeated as the ambient temperature rises and falls, which greatly reduces the risk of leakage of the aerosol canister 800 and releases the liquid in the liquid storage element 100 as much as possible.

[0036] In the aerosol cannon 800 of this utility model, such as Figure 2 As shown, the through-hole 2903 of the gas-liquid exchange element is disposed within the core 2901 of the gas-liquid exchange element. Figure 3 As shown, the through hole 2903 of the gas-liquid exchange element is disposed 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 0.2mm to 2.0mm, such as 0.2mm, 0.3mm, 0.4mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, and 2.0mm.

[0038] Preferably, the gas-liquid exchange element core 2901 is made of a porous material, such as porous plastic, porous ceramic, or porous metal, and more preferably a fiber-bonded porous material. Liquid conduction is rapid in fiber-bonded porous materials, which is beneficial for improving the sensitivity of gas-liquid exchange.

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

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

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

[0042] like Figure 6 As shown, the mesh heating element 931 includes a straight transverse resistance wire 9311 and a straight connecting resistance wire 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 metals such as iron, chromium, nickel, titanium, and aluminum. Wires 933 can be soldered onto the mesh to facilitate electrical connection between the atomizing core 930 and external components.

[0044] In the aerosol bullet 800 of this utility model, the mesh heating element 931 is bent and wrapped around the outer periphery of the atomizing core liquid guiding element 932. Figure 4 or Figure 6 The mesh heating element 931 shown is rolled up from left to right and covers the outer periphery of the atomizing core liquid guiding element 932, thus forming a... Figure 7 The atomizing core 930 is shown. To increase atomization efficiency, it is preferable that the mesh heating element 931 covers the outer periphery of the atomizing core liquid guiding element 932 by at least 180°, more preferably, the mesh heating element 931 covers the outer periphery of the atomizing core liquid guiding element 932 by at least 270°, and most preferably, the mesh heating element 931 covers the outer periphery of the atomizing core liquid guiding element 932 by at least 330°.

[0045] Will as Figure 5 The mesh shown is rolled up from top to bottom and wrapped around the outer periphery of the atomizing core liquid guiding element 932 to form a shape like... Figure 8 The atomizer core shown is 930.

[0046] In this embodiment, one end of the gas-liquid exchange element 290 is blocked by the atomizing core 930, which helps to create a negative pressure in the liquid storage element 100, significantly reducing the liquid content in the atomizing core liquid guiding element 932. Since the mesh heating element 931 covers the outer periphery of the atomizing core liquid guiding element 932, the liquid in the liquid storage element 100 is transferred through the gas-liquid exchange element 290 to both ends of the atomizing core liquid guiding element 932, and then conducted to the contact area between the atomizing core liquid guiding element 932 and the mesh heating element 931 and heated and evaporated. Therefore, the liquid atomized by this utility model patent technology is greatly reduced under the same heating power and heating time, resulting in finer aerosol particles and drier aerosol, greatly reducing the sweetness caused by large glycerin particles, making it very suitable for electronic nicotine delivery systems with tobacco flavor.

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

[0048] Second Embodiment

[0049] Figure 9 This is a schematic diagram of the structure of an aerosol cannon according to the second embodiment of the present invention; Figure 10 This is a schematic diagram of another aerosol cannon according to a second embodiment of the present invention. This embodiment is similar to the first embodiment, and the similarities with the first embodiment will not be repeated.

[0050] like Figure 9 and Figure 10 As shown, the aerosol bullet 800 of this embodiment includes a liquid storage element 100, an atomizing core 930, and an aerosol channel 1303, as well as a gas-liquid exchange element 290 connecting the liquid storage element 100 and the atomizing core 930. The atomizing core 930 includes an atomizing 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 axially penetrating the gas-liquid exchange element 290. The end of the gas-liquid exchange element through hole 2903 that contacts the atomizing core 930 is blocked by the atomizing core 930 or by the atomizing core liquid guiding element 932.

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

[0052] In the aerosol bullet 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 or non-woven fabrics made of materials such as ceramic fibers, cellulose fibers, glass fibers, and carbon fibers. 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 a mesh heating element 931 is attached to one or both sides of the non-woven fabric.

[0053] like Figure 9 As 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 airflow entering from the air inlet 1121 blows the lower surface of the mesh heating element 931 of the atomizing core 930, and the generated mist escapes from the mist outlet through the mist channel 1303.

[0054] like Figure 10 As 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 atomization channel 1303 is located on the other side of the mesh heating element 931. The atomization 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 axis of the atomization channel 1303 and the central axis of the air inlet 1121 are located on opposite sides of the central axis of the liquid storage element 100. During operation, the airflow entering through the air inlet 1121 can sweep the upper surface of the mesh heating element 931 of the atomizing core 930, and the generated atomization escapes from the atomization outlet through the atomization channel 1303.

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

[0056] This implementation uses a sheet-like mesh heating element 931 combined with a sheet-like atomizing core liquid guiding element 932, such as a die-cut non-woven fabric sheet, which makes assembly more convenient and reduces costs.

[0057] The working principle of the aerosol bullet 800 and the atomizing device according to the second embodiment is the same as that of the first embodiment.

[0058] In summary, the aerosol cartridge 800 of this invention has a simple structure and good leak-proof performance. Compared with existing technologies, the aerosol cartridge of this invention can produce finer aerosol particles and greatly eliminates the sweetness caused by large glycerin particles. Compared with heating elements formed by resistance wire braiding, the resistance of the mesh heating element is more stable, which is conducive to more precise control of the atomization system. The atomization device using the aerosol cartridge 800 of this invention is convenient to use and provides stable atomization. The aerosol cartridge 800 and atomization device of this invention are suitable for applications such as electronic nicotine delivery systems for tobacco flavors and drug solution atomization.
