The appearance of this phrase at various positions in the description does not necessarily refer to the same embodiment, nor is it an exclusive, independent or alternative embodiment that is mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described in this utility model can be combined with other embodiments.

[0019] In order to enable those skilled in the technical field to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] As Figure 1 and Figure 2 shown, an atomizer cartridge with a liquid leakage prevention structure of this utility model includes an atomizer main body 1. An oil storage chamber 101 and an oil leakage chamber 102 are arranged in the atomizer main body 1. An atomization core assembly is arranged in the oil storage chamber 101. A circulating oil hole 103 is arranged between the oil leakage chamber 102 and the oil leakage chamber 102. An oil-attracting tube 5 is arranged in the oil leakage chamber 102. A pressure relief hole 121 cooperating with the oil leakage chamber 102 is arranged on the atomizer main body 1. The oil-attracting tube 5 has oil-attracting property, the inner wall of the oil-attracting tube 5 is inclined, and the oil-attracting tube 5 can cooperate with the circulating oil hole 103 to lock the e-liquid on the inner wall during the pressure relief process.

[0021] The oil-attracting tube 5 is made of an oil-attracting material (or has oil-attracting property after surface treatment), that is, the oil contact angle is less than 90°.

[0022] The atomizer cartridge with a liquid leakage prevention structure further includes a first oil sealing member 7 and a second oil sealing member 8. An inner oil wicking tube 6 is arranged inside the oil wicking tube 5. The outer wall of the inner oil wicking tube 6 is inclined. An oil tube installation position matching with the inner oil wicking tube 6 is arranged inside the atomizer main body 1. The first oil sealing member 7 is arranged inside the inner oil wicking tube 6, and the second oil sealing member 8 is arranged outside the oil wicking tube 5.

[0023] The inner oil wicking tube 6 has oil wicking property, and the inner oil wicking tube 6 can cooperate with the circulating oil hole 103 to lock the e-liquid on the outer wall during the pressure relief process.

[0024] Through the arrangement of the first oil sealing member 7, it can prevent the e-liquid in the oil storage chamber 101 from leaking from the inside of the inner oil wicking tube 6 into the oil leakage chamber 102.

[0025] Through the arrangement of the second oil sealing member 8, it can prevent the e-liquid in the oil storage chamber 101 from leaking from the outside of the oil wicking tube 5 into the oil leakage chamber 102.

[0026] When in a negative pressure state, the e-liquid in the oil storage chamber 101 flows through the circulating oil hole 103 to the oil leakage chamber 102, contacting the inner wall of the oil wicking tube 5 and the outer wall of the inner oil wicking tube 6. Since the oil wicking tube 5 and the inner oil wicking tube 6 have oil wicking property, the flowing e-liquid will hang on the inner wall of the oil wicking tube 5 and the outer wall of the inner oil wicking tube 6 to form an oil film layer and will not flow into the pressure relief hole 121. When the pressure returns to normal, air exchange is carried out through the pressure relief hole 121, and the e-liquid on the inner wall of the oil wicking tube 5 and the outer wall of the inner oil wicking tube 6 returns to the oil storage chamber 101 again through the circulating oil hole 103.

[0027] The angles between the inner wall of the oil wicking tube 5 and the outer wall of the inner oil wicking tube 6 and the vertical direction are both in the range of 30° - 90°.

[0028] The materials of the first oil sealing member 7 and the second oil sealing member 8 are both silica gel. Through the setting of silica gel, the cost can be controlled while achieving a good sealing effect.

[0029] The material of the oil wicking tube 5 is steel, and the overall support is stronger due to the steel material.

[0030] The heights of the oil wicking tube 5 and the inner oil wicking tube 6 are different. In this embodiment, the height of the inner oil wicking tube 6 is higher than that of the oil wicking tube 5. By setting the upper ends at different heights, the e-liquid circulation is made more smooth.

[0031] The atomizer main body 1 includes an atomizer main housing 11 and an atomizer bottom housing 12 arranged at the lower end of the atomizer main housing 11. The oil storage chamber 101 is arranged above the oil leakage chamber 102. The pressure relief hole 121 is arranged on the atomizer bottom housing 12, and the atomizer main housing 11 and the atomizer bottom housing 12 are connected by snap fit.

[0032] The number of the circulating oil holes 103 is two groups, and the number of the pressure relief holes 121 is also two groups. The two groups of circulating oil holes 103 are symmetrically arranged relative to the atomizing core assembly, which can further relieve pressure and prevent oil leakage.

[0033] A mouthpiece is arranged on the atomizer body 1. The atomizing core assembly includes an upper silica gel 2 of the atomizing core, an atomizing core body 3 and a lower silica gel 4 of the atomizing core. The lower end of the upper silica gel 2 of the atomizing core is arranged at the upper end of the atomizing core body 3, and the upper end of the upper silica gel 2 of the atomizing core is arranged at the lower end of the mouthpiece. A main air hole 122 matching with the atomizing core assembly is arranged on the atomizer bottom shell 12. The main air hole 122 extends inward to be provided with a main air seat. The upper end of the lower silica gel 4 of the atomizing core is connected with the atomizing core body 3. The lower end of the lower silica gel 4 of the atomizing core passes through the inner oil-absorbing tube 6 and is connected with the main air seat. The first oil-sealing member 7 is sleeved on the outer wall of the main air seat. The lower silica gel 4 of the atomizing core is arranged above the first oil-sealing member 7. The lower silica gel 4 of the atomizing core can cooperate with the first oil-sealing member 7 to position and seal the inner side of the inner oil-absorbing tube 6.

[0034] As can be seen from the above, the beneficial effects of the present utility model are as follows: By adopting its mechanism, the problems of oil leakage or low utilization rate of e-liquid in the existing atomizing cigarette cartridge can be effectively solved. Through the use of the product structure, the e-liquid circulates between the oil storage chamber 101 and the oil leakage chamber 102 through the circulating oil holes 103, and the leaked e-liquid is locked by the oil-absorbing tube 5. The air is exchanged between the circulating oil holes 103 and the pressure relief holes 121, reducing the probability of oil leakage, ensuring the utilization rate of e-liquid, effectively improving the user experience, and being beneficial to enhancing the competitiveness of the enterprise.
