[0025] The present invention will be further described below in conjunction with the drawings and specific implementation manners.

[0026] As Figures 1 to 6As shown in the figure, a reusable heating core component switch-sealed oil storage cartridge electronic cigarette includes a cartridge component 1 and a heating core component 2. The cartridge component 1 includes a cartridge oil storage 111, a hollow tube 12, and a sealing body 13. The hollow tube 12 is docked with the cartridge oil storage 111. The hollow tube 12 is provided with a hollow tube oil guiding hole 121. The sealing body 13 is movably connected inside the hollow tube 12. When the cartridge component 1 is not assembled, the sealing body 13 blocks the hollow tube oil guiding hole 121. The heating core component 2 includes a heating core 21. The heating core 21 is provided with a heating core oil guiding hole 212. When the cartridge component 1 and the heating core component 2 are assembled, the heating core 21 is docked with the sealing body 13, and the heating core 21 pushes open the sealing body 13 so that the cartridge oil storage 111, the hollow tube oil guiding hole 121, the hollow tube 12, and the heating core oil guiding hole 212 are communicated. The heating core 21 and the sealing body 13 are detachably connected.

[0027] The cartridge component 1 is for single use and is discarded after use, while the heating core component 2 is an independent detachable and recyclable component, which can save costs and realize the reuse of parts.

[0028] The cartridge oil storage 111, the hollow tube 12, the sealing body 13, and the heating core 21 are coaxially installed to achieve the penetration of the flue.

[0029] The heating core 21 is provided with an inverted buckle structure 211. The sealing body jack 131 is provided with a clamping groove 132 that cooperates with the inverted buckle structure 211. The inverted buckle structure 211 is provided with a guiding slope 2111, which can easily slide into the clamping groove 132 of the sealing body 13. The heating core 21 can drive the sealing body 13 to move upward to the inside of the hollow tube 12, and the sealing body 13 avoids the hollow tube oil guiding hole 121, so that the hollow tube oil guiding hole 121 is communicated with the heating core oil guiding hole 212.

[0030] When the heating core component 2 is pulled out from the cartridge component 1, after the inverted buckle structure 211 drives the sealing body 13 to reset to block the hollow tube oil guiding hole 121, the heating core 21 is pulled out. When the heating core component 2 is pulled out of the cartridge component 1, under the action of the inverted buckle structure 211, the sealing body 13 moves from the inside of the hollow tube 12 to the outside of the hollow tube 12. At this time, the hollow tube oil guiding hole 121 is blocked by the sealing body 13 again. When a greater force is applied, the heating core 21 can be pulled out from the sealing body 13.

[0031] When the heating core assembly 2 moves downward (i.e. when it is pulled out), the heating core 21 drives the sealing body 13 to move downward to the first position, thereby sealing the hollow tube oil guide hole 121 and sealing the cartridge oil bin 111. At this time, the heating core 21 continues to move downward. Because the sealing body 13 is soft rubber, when it is pulled out with greater force, the inverted structure 211 of the heating core 21 can be disengaged from the card slot 132 of the sealing body 13, thereby realizing the separation of the heating core assembly 2 and the cartridge assembly 1, and, during separation, the cartridge oil bin 111 can be sealed, providing a basis for the reuse of the heating core assembly 2.

[0032] The undercut size of the undercut structure 211 of the heating core 21 should be at least 0.4 mm, and the inner diameter of the sealing body insertion hole 131 of the sealing body 13 should be greater than 3.5 mm.

[0033] An upper sealing ring 133 and a lower sealing ring 134 are provided on the outer side of the sealing body 13. The upper sealing ring 133 and the lower sealing ring 134 are respectively sealed with the hollow tube 12. When the sealing body 13 is located outside the hollow tube 12, the hollow tube oil guide hole 121 is located between the upper sealing ring 133 and the lower sealing ring 134, which can avoid oil leakage.

[0034] The hollow tube 12 is provided with a first stop portion 122 for limiting the inward movement depth of the sealing body 13 . When the sealing body 13 is pushed in and reaches the first stop portion 122 , it stops moving.

[0035] A plurality of upper sealing rings 133 , for example, two, may be provided to enhance the sealing effect.

[0036] A plurality of lower sealing rings 134 , for example, two, may be provided to enhance the sealing effect.

[0037] The upper sealing ring 133 and the lower sealing ring 134 are preferably O-rings, which seal the oil guide hole 121 of the hollow tube through interference fit with the hollow tube 12 .

[0038] The cigarette cartridge assembly also includes an oil cup body 11, an oil cup base sealing body 14 and an oil cup base 15. The hollow tube 12 is installed on the oil cup body 11. The oil cup base 15 is connected to the oil cup body 11. The oil cup base sealing body 14 is clamped between the oil cup base 15 and the oil cup body 11. The hollow tube 12 is installed between the oil cup body 11 and the oil cup base sealing body 14. The inner wall of the oil cup body 11, the outer wall of the hollow tube 12 and the oil cup base sealing body 14 form a cigarette cartridge oil bin 111.

[0039] The oil cup base seal 14 is provided with a second stop portion 141 for limiting the outward movement depth of the seal 13 . When the seal 13 is pulled out along with the heating core 12 , the seal 13 stops moving after reaching the second stop portion 141 .

[0040] The oil cup base seal 14 is preferably made of silicone for the oil cup base.

[0041] The heating core assembly 2 includes a housing 23, a bracket 22, an oil-absorbing cotton 24, and an electrode 25. The housing 23 has an inner cavity. The bracket 22 and the oil-absorbing cotton 24 are respectively installed inside the inner cavity of the housing 23. A heating cavity is formed between the bracket 22 and the housing 23. The electrode 25 and the oil-absorbing cotton 24 are respectively located between the heating cavities. The heating core 21 is installed on the bracket 22.

[0042] The seal 13 is made of a soft material, preferably silicone, or materials such as TPU and TPE. Silicone is preferably used, also known as movable seal silicone.

[0043] The seal 13 and the hollow tube 12 are in interference fit, which can achieve the sealing of the hollow tube oil guiding hole 121 of the hollow tube 12.

[0044] The heating core 21, the seal 13, and the oil cup 11 are coaxially installed. Moreover, channels are provided on the central axes of the heating core 21, the seal 13, and the oil cup 11, which can be connected to form a flue. This flue is communicated with the heating cavity.

[0045] A reusable heating core component switch-sealed oil storage cartridge e-cigarette provided by the present utility model realizes the sealing and opening of the cartridge oil storage 111 by designing a seal 13 inside the hollow tube 12. When in the sealed state, the heating core component 2 is not inserted into the cartridge component 1, and the cartridge component 1 is in the sealed state. Without the heating core component 2, the user cannot use it. When in the open state, the heating core component 2 is inserted into the cartridge component 1, synchronously pushing the seal 13 to open the sealing effect on the hollow tube oil guiding hole 121. The oil is introduced into the interior of the heating cavity through the hollow tube oil guiding hole 121 and the heating core oil guiding hole 212, and the user can smoke normally.

[0046] A reusable heating core component switch-sealed oil storage cartridge e-cigarette provided by the present utility model can open the cartridge oil storage 111 when the heating core 21 is inserted, so that the cartridge can work properly during use. When pulled out, the original sealed state of the cartridge oil storage 111 can be restored.

[0047] A reusable heating core component switch-sealed oil storage cartridge e-cigarette provided by the present utility model separates the heating core 21, the bracket 22, the housing 23, the oil-absorbing cotton 24, and the electrode 25 to form a detachable and recyclable heating core component 2. After a consumer uses up a cartridge, the heating core component 2 can be separately disassembled and then inserted into another full-oil cartridge.

[0048] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
