A common technique in electronic atomized cigarettes is to heat an atomizing core liquid-conducting element, such as a glass fiber bundle or a cotton fiber bundle, that is in direct communication with the tobacco tar, to atomize the liquid. The atomization chamber cavity and the atomization core liquid guide element need to be matched properly, so that external air enters the liquid storage element from a gap between the atomization core liquid guide element and the atomization chamber cavity while liquid is conducted from the atomization core liquid guide element. Because fine glass is restrainted and cotton fiber bundle is soft and lack fixed shape for the clearance between atomizing core drain component and the atomizer chamber cavity is difficult with precision control, and the liquid on the atomizing core is too much when the clearance is too big, can explode oil during the atomizing, can the weeping when serious, and the air is difficult to get into stock solution component when the clearance undersize, and then leads to the atomizing core to lack the liquid and paste the core, and these all influence atomizing stability and consumption experience.

When liquid is led out from the liquid storage element, negative pressure in the liquid storage element is increased, the liquid in the gas-liquid channel is absorbed by the fluid core body, the liquid seal of part or all of the gas-liquid channel disappears, air in the atomizing chamber enters the liquid storage element through the gas-liquid channel, and when the vacuum degree in the liquid storage element is reduced to a balance state, the gas-liquid channel is sealed again. In the technology, because the liquid flow path in the fiber-bonded fluid core is relatively tortuous, the liquid flow speed is relatively low, and particularly when the temperature is relatively low, the viscosity of the electronic cigarette liquid mainly containing propylene glycol and glycerin is relatively high, the atomized core is easy to cause insufficient liquid supply to influence the taste and even paste the core.

Fig. 1a is a schematic structural view of an aerosol bomb having an atomizing core according to a first embodiment of the present invention; fig. 1 b-1 e are various schematic cross-sectional views of a relay liquid-guiding member in a capillary passage according to the first embodiment.
As shown in fig. 1a to 1e, the atomizing core 930 according to the first embodiment of the present invention includes a capillary passage relay liquid guiding element 939 for conducting liquid, an atomizing core liquid guiding element 932 for receiving liquid disposed on the outer periphery of the capillary passage relay liquid guiding element 939, and a heat generating element 931 for heating the atomizing core liquid guiding element 932 to atomize the liquid, the atomizing core liquid guiding element 932 is a non-woven fabric, and the capillary passage relay liquid guiding element 939 includes a relay liquid guiding element core 9391 and at least two capillary passages 9392 axially penetrating the relay liquid guiding element core 9391.
The capillary passage 9392 transports the liquid to the atomizing core liquid-guiding member 932 by its capillary force, and the capillary passage relay liquid-guiding member 939 has both a liquid-guiding function and an air-guiding function.
In this embodiment, as shown in fig. 1a, a surface of the capillary passage intermediate liquid guiding element 939 is covered with a non-woven fabric as an atomizing core liquid guiding element 932, and a spiral heating wire is covered on the non-woven fabric as a heating body 931.
In the present invention, the capillary channel 9392 has an inner peripheral wall capable of being infiltrated by liquid, and those skilled in the art can process the inner peripheral wall of the capillary channel 9392 or coat or add hydrophilic material on the inner peripheral wall of the capillary channel 9392 through the selection of the material, so that the inner peripheral wall of the capillary channel 9392 can be infiltrated by liquid.
In the present invention, liquid can flow in the capillary channel 9392 under the surface tension of the liquid and the capillary force of the atomizing wick wicking element 932. The capillary channels 9392 in the capillary channel relay liquid guiding element 939 are arranged in a linear or nearly linear manner along the axial direction, that is, the capillary channels 9392 in the capillary channel relay liquid guiding element 939 are parallel or substantially parallel to the axial direction of the capillary channel relay liquid guiding element 939, so that the liquid can flow in the capillary channels 9392 along the axial direction, and the structure is beneficial to reducing the liquid guiding resistance and reducing the risk of the atomizing core 930 being short of liquid.
As shown in fig. 1b to 1e, the capillary passage relay liquid guiding member 939 is preferably a radially open capillary passage 9392. The capillary passage relay liquid guiding element 939 may also comprise both a radially closed capillary passage 9392 and a radially open capillary passage 9392, in which case the portion of the capillary passage relay liquid guiding element 939 in contact with the atomizing wick liquid guiding element 932 is the radially open capillary passage 9392.

The capillary passage 9392 with a larger inscribed circle diameter has weaker liquid sealing capability and is suitable for application with higher viscosity or larger liquid output. In the equilibrium state the capillary channel 9392 is liquid-sealed due to capillary forces.
As shown in fig. 1e, capillary passage relay liquid guiding member 939 employs radially open capillary passage 9392, and in any cross section of capillary passage 9392, the maximum inscribed circle diameter at the top of capillary passage 9392 is smaller than the maximum inscribed circle diameter of capillary passage 9392. Specifically, a plurality of radially open grooves are formed on the outer peripheral portion of the relay liquid guiding member core 9391 of the capillary passage relay liquid guiding member 939, and the end portions of the partition walls of the adjacent grooves are formed with end portions gradually increasing in thickness and then gradually decreasing in thickness, or with end portions gradually increasing in thickness, so that in any cross section of the capillary passage 9392, the maximum inscribed circle diameter at the radial end portions of the capillary passage 9392 gradually decreases and then gradually increases, or the maximum inscribed circle diameter at the radial end portions of the capillary passage 9392 gradually decreases. This configuration may utilize the surface tension of the capillary passage 9392 to conduct liquid in the capillary passage 9392 toward the atomizing wick liquid-conducting element 932.
