When the electronic cigarette is affected by the external environment, or the internal negative pressure formed during use, the air pressure inside and outside the tube of the atomizer core is inconsistent, and the smoke oil will penetrate from the oil guide through hole of the atomizer core shell, resulting in oil leakage. To this end, the technical scheme aims to optimize and improve the atomizer core structure of the electronic cigarette. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, rather than all embodiments.

An inner tube body 11 is arranged at the inner lower end of the tubular shell 1, and an annular groove 110 is formed between the outer wall of the inner tube body 11 and the inner wall of the tubular shell 1. At least two through holes 112 are evenly arranged on the side wall of the tubular shell 1 corresponding to the bottom of the annular groove 110 for exhausting and draining oil. The lower end of the inner tube body 11 extends downward to form a plug-in end, and the oil guide element 2 is placed above the inner tube body 11 in the tubular shell 1.

The steam smoke generated by the atomized smoke oil passes through the connecting tube 4 with a smaller diameter and enters the atomizing air outlet pipe 5 with a larger diameter, so that the smoke output has a stronger ejection impact and a better smoke-raising effect.

[0023] Preferably, 2 to 4 connecting ribs 111 are evenly arranged between the outer wall of the inner tube body 11 and the inner wall of the tubular shell 1, and the upper end of the connecting rib 111 is flush with the upper end of the inner tube body 11. The setting of the connecting rib 111 is beneficial to the one-piece molding of the mold on the one hand, and on the other hand, the upper end of the connecting rib 111 is also beneficial to pad the oil guide element 2. The oil guide element 2 is preferably made of oil-absorbing cotton made of non-woven fabric. When the oil-absorbing cotton has too much oil, it flows into the annular groove 110 through the connecting rib 111 and the outer wall of the inner tube body 11 and the inner wall of the tubular shell 1, and flows to the bottom of the annular groove 110 due to gravity. The annular groove 110 forms a liquid collection area and is separated from the atomization channel, which does not affect the normal use of the atomization core. The heating element 3 is used to atomize the e-liquid, and the oil in the annular groove 110 is reabsorbed by the oil storage cotton wrapped outside the atomization core structure through the through hole 112 at the bottom of the annular groove 110, thereby preventing the oil of the electronic cigarette from leaking from the atomization core to the suction nozzle or the atomization channel.

[0024] Preferably, a notch 12 is provided on the side wall of the tubular housing 1 from the upper end downward, the lower end of the notch 12 is higher than the upper end of the inner tube 11, the oil guide element 2 is made of non-woven fabric, the heating element 3 includes a heating wire mesh 31 and positive and negative electrode needles 32 in a cylindrical shape, the oil guide element 2 wraps the outer wall of the heating wire mesh 31, and the oil guide element 2 passes through the notch 12. Preferably, oil guide cotton made of non-woven fabric is used as the oil guide element 2, the cylindrical heating wire mesh 31 is wrapped by closing the block of oil guide cotton from the middle to both sides, and then the two ends of the oil guide cotton pass through the notch 12.

[0025] Preferably, the outer wall of the connecting tube 4 is provided with a convex edge 41 which is inserted into the notch 12 and abuts against the upper port of the tubular housing 1. The outer wall of the connecting tube 4 which is inserted into the upper end of the tubular housing 1 is provided with a hemispherical convex point 42, and the inner wall of the upper port of the tubular housing 1 is provided with a hemispherical concave point 14, and the hemispherical convex point 42 and the hemispherical concave point 14 are snap-fitted with each other.

[0026] Preferably, the side wall of the tubular housing 1 opposite to the notch 12 is provided with an exhaust port 13, and the tubular housing 1 and the inner tube body 11 are formed in one piece using PCTG material, or brass electroplated with chrome, or brass plated with nickel, or 304 stainless steel. The exhaust port 13 is a square port that occupies a larger area, and the square port must ensure that the upper end of the oil guide element 2 is higher than the height of the square port, and the lower end of the square port is higher than the lower end of the oil guide element 2, so as to ensure that one side of the oil guide element 2 as a whole will not pass through the square port, and a larger diameter exhaust port 13 is realized through the square port, so as to achieve a better exhaust effect.

[0027] Example 2

[0028] Reference Figure 5 , Figure 6This is a schematic diagram of an embodiment of an oil cup body made in combination with the atomizer core structure disclosed in this solution, and a disposable electronic cigarette provided with the oil cup body. Figure 5 The oil cup body includes a straight tube that is hollow and has openings at the upper and lower ends, an oil storage integrated cotton arranged in the straight tube, and upper and lower silicone rubber arranged at the upper and lower ends of the straight tube.
