Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an oil storage atomizing component for controlling the amount of oil entering the device and an electronic cigarette. Background Technology

[0002] Electronic cigarettes are tobacco substitutes that use electrically heated e-liquid to create vapor aerosol smoke particles for users to inhale. Their core components include, but are not limited to, a casing, an e-liquid reservoir, an atomizer core, a battery, and a control board. The atomizer core is axially mounted within the e-liquid reservoir, with the upper end connecting the mouthpiece and the hollow channel of the atomizer core. The lower end of the reservoir is sealed by an oil-sealing element, sealing the lower inner wall of the reservoir and the outer wall of the atomizer core. This is an open-oil type e-cigarette e-liquid atomizer assembly, where the atomizer core is always immersed in e-liquid. E-liquid is guided into the wicking cotton inside the atomizer core through an inlet hole on the side wall of the atomizer core assembly. The wicking cotton contains an electric heating wire. In this open-oil type e-cigarette e-liquid atomizer assembly, under a large pressure difference between the internal and external e-liquid, e-liquid is prone to overflow from the hollow channel of the atomizer core. The outer wall of the atomizer core assembly directly contacts the e-liquid, easily leading to oxidation, discoloration, and off-flavor of the e-liquid.

[0003] Existing e-cigarette atomizing components using integrated polymer e-liquid storage cotton for adsorption and locking in e-liquid have an integrated storage cotton inside the e-liquid cup. This cotton has a hollow section running through its top and bottom, within which the atomizer coil is located. E-liquid is injected into the cotton for adsorption. During use, the inhalation nozzle creates negative pressure within the atomizer coil, drawing the e-liquid from the cotton to the heating wire, thus atomizing it. The integrated cotton has a certain degree of e-liquid locking, making it less prone to leakage compared to open-oil e-cigarettes, but it's not completely leak-proof, especially if the cotton holds a large amount of e-liquid. Similarly, in these integrated cotton atomizing components, the e-liquid is immersed in the cotton for an extended period. The e-liquid contains PG, VG, and various flavorings and additives, and these organic substances undergo slow chemical reactions, including alcoholization and oxidation. If e-liquid is soaked in the e-liquid reservoir for an extended period, especially if the reservoir fibers are loosely arranged and have good oil-wicking and oil-retention properties, the e-liquid is more likely to come into contact with air, undergoing an oxidation reaction and causing it to deteriorate. Further research and development are needed to overcome these technical challenges in the design of the e-cigarette e-liquid atomization components described above. Utility Model Content

Through the design of the air passing groove 301 and the blocking portion 214, the position of the floating piece 5 floating up is limited, and the air passing groove 301 and the air hole 212 make the hollow chamber 21 not in a vacuum state during use of the electronic cigarette. Air is connected into the hollow chamber 21 from the air hole 212, so that the floating piece 5 can descend with the tobacco liquid surface under the action of gravity.

[0039] As a preferred, the second shell 2 and the hollow chamber 21 are integrally injection molded by using a food-grade plastic material.

[0040] As a preferred, the second shell 2 and the hollow chamber 21 are in a cylindrical shape, the floating piece 5 is also in a cylindrical shape, and the upper and lower end edges of the floating piece 5 are in a chamfered arc edge.
