As shown in fig. 1b, the outer surface of the portion of the wick 932 in the chamber through-hole 9341 according to this embodiment is provided with one or more grooves a that extend out of both ends of the chamber through-hole 9341, or one or more grooves a may axially penetrate the outer surface of the wick 932, thereby forming one or more air guide channels 836 that communicate the outside of the atomizing chamber 934 with the outer peripheral wall of the wick 932 between the inner peripheral wall of the chamber through-hole 9341 and the outer peripheral wall of the wick 932. Because recess A extends the both ends of atomizer chamber through-hole 9341, recess A extends the outside part of atomizer chamber 934 and can regard as the outside air guide mouth of atomizer chamber 934, and recess A extends the inside part of atomizer chamber 934, can regard as the inside air guide mouth of atomizer chamber 934. The inner peripheral wall of the atomizer chamber through hole 9341 and the outer peripheral wall of the liquid guide core 932 are tightly fitted, and there is no other gap capable of air guiding between the inner peripheral wall of the atomizer chamber through hole 9341 and the outer peripheral wall of the liquid guide core 932 except for the air guide channel 836 formed by the groove a.

One or more air guide channels 836 communicating the outside of the atomizing chamber 934 and the atomizing chamber 934 are thereby formed between the inner peripheral wall of the atomizing chamber through hole 9341 and the outer peripheral wall of the liquid guide core 932. Because recess B extends to the both ends of atomizer chamber through-hole 9341, recess B extends to the outside port of atomizer chamber 934 and can regard as the outside air guide mouth of atomizer chamber 934, and recess B extends to the inside port of atomizer chamber 934, can regard as the inside air guide mouth of atomizer chamber 934.

According to the present embodiment, it is also possible to have a gap between the inner peripheral wall of the atomizing chamber through hole 9341 and the outer peripheral wall of the liquid-guiding core 932, the gap serving as an air-guiding passage. For example, the wick 932 may be configured with different cross-sectional sizes, such as a circular cross-section for the chamber opening 9341 and a circular cross-section for the wick 932, but the former has a larger diameter than the latter, and when the wick 932 is nearly tightly fitted in the chamber opening 9431, a gap is formed between the inner peripheral wall of the chamber opening 9341 and the outer peripheral wall of the wick 932, thereby forming an air-guiding channel 836 that communicates the outside of the atomizing chamber 934 and the atomizing chamber 934. The cross-sections of the atomizing chamber through hole 9341 and the liquid guide core 932 can also be designed into different geometric shapes, for example, the cross-section of the atomizing chamber through hole 9341 is oval or rectangular, and the cross-section of the liquid guide core 932 is circular. When the wick 932 is nearly tightly fitted in the chamber throughbore 9341, a gap is formed between the inner peripheral wall of the chamber throughbore 9341 and the outer peripheral wall of the wick 932 due to the difference in geometry, thereby forming one or more air guide channels 836 that communicate between the exterior of the atomizing chamber 934 and the atomizing chamber 934.
According to this embodiment, one or more separately formed air ducts communicating the outside of the atomizing chamber 934 and the atomizing chamber 934 may also be interposed between the inner peripheral wall of the closely fitted atomizing chamber through hole 9341 and the outer peripheral wall of the liquid guide 932 as air duct 836.

In applications where the amount of atomization is small or the viscosity of the liquid is low, the maximum inscribed circle diameter of the cross-section of the air guide channel 836 is preferably set small. Conversely, the maximum inscribed circle diameter of the cross-section of the airway channel 836 is preferably set large.
The liquid conducting core 932 has a density of 0.15 g/cm3To 0.45 g/cm3E.g. 0.15 g/cm30.175 g/cm30.2 g/cm30.225 g/cm30.25 g/cm30.275 g/cm30.3 g/cm30.35 g/cm30.4 g/cm30.45 g/cm3Preferably 0.2 to 0.35 g/cm3. When the density is less than 0.15 g/cm3In this case, the strength of the liquid guide core 932 is insufficient. When the density is more than 0.45 g/cm3In time, the liquid guiding speed is slow, which affects the atomization effect.

The wick 932 may be formed from bicomponent fibers 2 of sheath-core construction via thermal bonding. The sheath 21 and core 22 of the bicomponent fiber 2 may be of a concentric configuration as shown in fig. 1d or of an eccentric configuration as shown in fig. 1 f.
The core layer 22 of the bicomponent fiber 2 should have a melting point higher than that of the sheath layer 21 by more than 20 ℃, so that the core layer 22 can maintain certain rigidity during thermal bonding between fibers, and the liquid guide core 932 with uniform gaps can be conveniently manufactured. In order to meet the requirement of heating atomization, the melting point of the skin layer 21 of the bicomponent fiber 2 is preferably more than 210 ℃, and the skin layer 21 can be PBT, PTT, PET or co-PET, etc. The wick 932 may be formed by bonding synthetic fibers having a melting point of more than 210 ℃ with a binder, or may be formed by bonding vegetable fibers with a binder, or may be formed by sintering glass fibers. The fibers making up the liquid-conductive core 932 may be staple or filament, but are preferably filament. Further, the wick 932 may also be porous ceramic.

The heating element 931 may be a thick film heating element, and the thick film heating element partially surrounds the elliptical liquid guide core 932. The heating element 931 may be a flat thick film heating element which is in contact with or close to the surface of the flat liquid guide core 932.
The atomizing core 930 may further include an intermediate layer 9321 disposed between the liquid guide core 932 and the heat-generating body 931. In order to improve the high temperature resistance of the atomizing core 930, an intermediate layer 9321 may be added between the liquid guiding core 932 and the heat generating element 931, the intermediate layer 9321 may be made of fibers, woven fabrics or non-woven fabrics made of plant fibers, for example, the intermediate layer 9321 may be wound on the liquid guiding core 932 and then the heat generating element 931 may be wound, or the intermediate layer 9321 may be added between the thick film heat generating element 931 and the liquid guiding core 932.
As shown in fig. 1a, an aerosol bomb 800 according to the first embodiment comprises an atomizing element according to the first embodiment. The aerosol cartridge 800 according to the first embodiment further includes a liquid storage member 100 communicating with the atomizing chamber 934 through the atomizing chamber through hole 9341 and an aerosol passage 1303 communicating the atomizing chamber 934 with the outside. The atomizing chamber 934 includes a connection port provided at the top of the atomizing chamber 934 and connected to the aerosol channel 1303, and one end of the aerosol channel 1303 is connected to the connection port.
The liquid storage element 100 is a component for storing liquid in the aerosol bomb 800, and liquid to be atomized, such as electronic cigarette liquid, cannabidiol solution, drug solution, etc., is injected into the liquid storage element 100. The reservoir component 100 may be a cavity made of plastic or metal. The centerline of the aerosol passage 1303 preferably coincides with the centerline of the reservoir member 100, i.e., the aerosol passage 1303 is disposed centrally within the interior of the reservoir member 100.

The reservoir housing bottom seal 112 is used to seal the bottom of the reservoir 100 and the bottom of the aerosolizing chamber 934.
After the aerosol bomb 800 is assembled, the liquid is injected, and the liquid permeates the liquid guiding core 932 to reach equilibrium, and a certain negative pressure is formed in the liquid storage element 100. Due to capillary forces, the gas-liquid exchange system is balanced and the gas-conducting channel 836 is liquid-sealed. In use, the atomizing core 930 is heated while passing an air flow through the seal portion air inlet 1121 and the atomizing chamber 934. The liquid on the atomizing core 930 is atomized and escapes from the aerosol channel 1303, and the liquid guide core 932 absorbs the liquid from the liquid storage element 100 and replenishes the liquid to the middle of the atomizing core 930. As atomization proceeds, the negative pressure in the reservoir 100 increases, and air in the atomizing chamber 934 enters the reservoir 100 through the air-conducting channel 836 until the air-liquid exchange system is re-equilibrated. The wick 932 and the gas channel 836 thus form a stable gas-liquid exchange system in the atomizing element, thereby achieving a smooth atomization process.
