Description

Technical Field

[0001] This application relates to the field of electronic cigarette technology, and in particular to an electronic cigarette. Background Technology

[0002] E-cigarettes are electronic products that mimic traditional cigarettes, producing similar smoke, taste, and sensation. However, they do not contain the tar and other harmful substances found in traditional cigarettes. E-cigarettes work by heating e-liquid to produce vapor, which users inhale to obtain nicotine and other components. Current e-cigarettes rely on e-liquid evaporation to produce nicotine and other components. After the e-liquid is consumed, it needs to be refilled. Currently, the refill port is typically sealed with a removable silicone plug. This open-ended refilling structure poses a risk of unauthorized injection of other unknown liquids, creating a safety hazard. Utility Model Content

[0010] In one embodiment, one end of the oil storage sleeve is provided with a smoke outlet, and a venting pipe is provided inside the oil storage sleeve. The venting pipe is connected to the smoke outlet and the atomizing component, and the sealing seat is sleeved on the venting pipe. The cross-sectional area of ​​the first connecting part is larger than the cross-sectional area of ​​the second connecting part, and the second connecting part is coaxially arranged with the venting pipe.

[0011] In one embodiment, the sealing seat is movably connected to the oil storage sleeve so that it can move axially along the first oil storage cavity when an external force is applied. The sealing seat is provided with an oil outlet hole communicating with the first oil storage cavity and the atomizing component so that when the sealing seat moves in the direction away from the atomizing component, the e-liquid in the first oil storage cavity can flow towards the atomizing component more rapidly.

[0012] In one embodiment, the oil cup assembly further includes a guide member, which is movably sleeved on the support and connected to the oil storage sleeve.

[0013] In one embodiment, the atomizing assembly includes a first housing, an atomizing sleeve, an atomizing base, and an atomizing core. The first housing is connected to the oil storage sleeve. The atomizing sleeve is at least partially inserted into the first housing, and a second oil storage chamber is provided inside the atomizing sleeve. An oil guide tube is provided at one end of the atomizing sleeve facing the oil cup assembly.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: Since the first end of the sealing plug is inserted into the refill hole, and the second end of the sealing plug abuts against the support seat, the sealing plug is located within the space formed by the sealing seat and the support seat. Therefore, after refilling and inserting the sealing plug into the refill hole, the sealing plug cannot be removed, thus preventing repeated refilling of e-liquid and eliminating the risk of arbitrarily injecting other unknown liquids. Furthermore, during production, before adding e-liquid, the sealing seat is first inserted into one end of the first oil storage chamber, then the support seat is inserted into the first positioning groove, and finally the e-liquid is added. This facilitates production and avoids the inconvenience caused by adding e-liquid too early. Attached Figure Description

[0026] Please refer to Figures 1-9 This application provides an embodiment of an electronic cigarette, which includes an oil cup assembly 1, an atomizing assembly 2, and a battery assembly 3. The oil cup assembly 1 includes an oil storage sleeve 11, a sealing seat 12, a support seat 13, a sealing plug 14, a guide 15, and a first magnet 16. One end of the oil storage sleeve 11 is provided with a smoke outlet 111, from which smoke is discharged when the user smokes. The oil storage sleeve 11 is provided with a first oil storage chamber 112 and a ventilation pipe 113. The first oil storage chamber 112 is used to store e-liquid. The ventilation pipe 113 is connected to the smoke outlet 111 and the atomizing assembly 2, and is used to discharge the smoke formed by the atomization of e-liquid by the atomizing assembly 2 to the smoke outlet 111.

[0027] A sealing seat 12 is inserted into one end of the first oil storage chamber 112 and sleeved on the vent pipe 113 to seal the opening of the first oil storage chamber 112. The sealing seat 12 is movably connected to the oil storage sleeve 11 so that it can move axially along the first oil storage chamber 112 when an external force is applied, that is, move towards or away from the smoke outlet 111.

[0028] The sealing seat 12 is provided with an oil filling hole 121, an oil outlet hole 122, a first positioning groove 123, and a second positioning groove 124. The oil filling hole 121 communicates with the first oil storage chamber 112, and e-liquid is added to the first oil storage chamber 112 through the oil filling hole 121 during production. The oil outlet hole 122 communicates with the first oil storage chamber 112 and the atomizing assembly 2, and the e-liquid in the first oil storage chamber 112 flows into the atomizing assembly 2 through the oil outlet hole 122. Both the first positioning groove 123 and the second positioning groove 124 are annular, but the annular structure can be a non-annular structure. The first positioning groove 123 is arranged around the second positioning groove 124, and the second positioning groove 124 is coaxially arranged with the first positioning groove 123.

[0029] The support base 13 includes a first connecting portion 131, a second connecting portion 132, and a support plate portion 133. Both the first connecting portion 131 and the second connecting portion 132 are annular and located on the same side of the support plate portion 133. The first connecting portion 131 is connected to the support plate portion 133 and inserted into the first positioning groove 123. The second connecting portion 132 is coaxially arranged with the first connecting portion 131 and the vent pipe portion 113, thus ensuring a tighter connection between the sealing seat 12 and the vent pipe portion 113, improving sealing performance and effectively preventing e-liquid leakage. The second connecting portion 132 is connected to the support plate portion 133 and inserted into the second positioning groove 124. The cross-sectional area of ​​the first connecting portion 131 is larger than the cross-sectional area of ​​the second connecting portion 132.

[0030] The oil filling hole 121 is located between the first connecting part 131 and the second connecting part 132. The support plate part 133 is located at the end face of the sealing plug 14. Since the second positioning groove 124 and the first positioning groove 123 are coaxially arranged, and the second connecting part 132 and the first connecting part 131 are respectively inserted into the second positioning groove 124 and the first positioning groove 123, when an external force pushes the support seat 13 to move towards the smoke outlet 111, the support seat 13 pushes the sealing plug 14 to move together towards the smoke outlet 111. The force on the sealing seat 12 is more balanced and it is not easy to deviate, thus reducing the probability of oil leakage between the sealing seat 12 and the oil storage sleeve 11.

[0031] Since the sealing seat 12 is movably connected to the oil storage sleeve 11, it can move along the axial direction of the first oil storage chamber 112 when an external force is applied. Therefore, when the sealing seat 12 moves in the direction away from the atomizing component 2, the e-liquid in the first oil storage chamber 112 can accelerate its flow toward the atomizing component 2 to quickly replenish the e-liquid.

[0032] Furthermore, the support plate portion 133 is provided with a clearance hole 1331, which corresponds to the position of the filler hole 121, and the cross-sectional area of ​​the clearance hole 1331 is larger than that of the filler hole 121. The first end of the sealing plug 14 is inserted into the filler hole 121, and the second end of the sealing plug 14 abuts against the support plate portion 133 of the support base 13. The sealing plug 14 is located within the space formed by the sealing base 12 and the support base 13. Therefore, even if the user pries the sealing plug 14 with their finger, the sealing plug 14 will not fall off, thus greatly reducing the probability of being injected with unknown liquids and greatly improving safety.

[0033] Specifically, the sealing plug 14 includes a sealing section 141 and a limiting section 142. The sealing section 141 and the limiting section 142 are connected and inserted into the oil filling hole 121. The cross-sectional area of ​​the limiting section 142 is larger than that of the sealing section 141, and the limiting section 142 extends into the clearance hole 1331. Since the cross-sectional area of ​​the limiting section 142 is larger than that of the sealing section 141, when the sealing plug 14 is inserted into the oil filling hole 121, the user can press the end face of the limiting section 142 to apply pressure to the sealing plug 14, thus facilitating the insertion of the sealing plug 14 into the oil filling hole 121. A limiting protrusion 1421 is provided on the outer peripheral surface of the limiting section 142, and the limiting protrusion 1421 abuts against the support plate portion 133. The sealing plug 14 is an elastomer made of silicone or rubber, and a cut 1422 is provided on the end face of the limiting section 142, which extends axially along the sealing plug 14. Therefore, when assembling the sealing plug 14, it is convenient to insert the limiting section 142 into the clearance hole 1331.

[0034] The guide member 15 is movably sleeved on the support base 13 and connected to the oil storage sleeve 11. Therefore, when the support base 13 is subjected to a force in the direction of the smoke outlet 111, the support base 13, together with the sealing seat 12, moves in the direction of the smoke outlet 111. Through the guiding effect of the guide member 15, the deflection of the sealing seat 12 can be better avoided, further reducing the probability of e-liquid leakage. Two first magnets 16 are fixed to the side wall of the oil storage sleeve 11, spaced apart from each other.

[0035] The atomizing component 2 is connected to the oil cup assembly 1 and is used to atomize the e-liquid in the oil cup assembly 1. It includes a first housing 21, an atomizing sleeve 22, an atomizing base 23, an atomizing core 24, and a porous suction column 25. One end of the first housing 21 is fitted onto the oil storage sleeve 11 and connected to the oil storage sleeve 11. The side wall of the first housing 21 is provided with a docking groove 211, and the groove wall of the docking groove 211 is provided with a first docking hole 212, which communicates with the atomizing core 24. The atomizing sleeve 22 is inserted into the first housing 21 and covers the end face of the sealing plug 14 facing the atomizing component 2. A second oil storage chamber 221 is provided inside the atomizing sleeve 22.

[0036] The atomizing sleeve 22 has an oil guide tube 222 at one end facing the oil cup assembly 1. The oil guide tube 222 is inserted into the oil outlet 122 and communicates with the first oil storage chamber 112 and the second oil storage chamber 221. The e-liquid in the first oil storage chamber 112 flows into the second oil storage chamber 221 through the oil guide tube 222. The atomizing base 23 covers one end of the second oil storage chamber 221 to seal the opening of the second oil storage chamber 221. The atomizing coil 24 is located in the second oil storage chamber 221 and fixed on the atomizing base 23, and is used to atomize the e-liquid in the second oil storage chamber 221. The atomizing coil 24 is prior art and will not be described in detail here. The porous suction column 25 is located in the second oil storage chamber 221 and sleeved on the atomizing coil 24. It can be made of porous ceramic or fiber and other porous materials. The atomizing assembly 2 and the battery assembly 3 are arranged side by side along the transverse direction of the electronic cigarette.

[0037] The battery assembly 3 is connected to the atomizing assembly 2 to provide electrical power. It includes a second housing 30, a mounting bracket 31, a control circuit board 32, an elastic sealing block 33, a battery 34, an airflow sensor 35, electrodes 36, and a second magnet 37. The side wall of the second housing 30 is provided with a mating protrusion 311 that inserts into the mating groove 211, thus making the connection between the battery assembly 3 and the atomizing assembly 2 more reliable. The second housing 30 includes a receiving shell 301 and a side cover 302 located on the side of the receiving shell 301. The mounting bracket 31 is located inside the second housing 30, and the control circuit board 32 is located inside the second housing 30 and electrically connected to the battery 34.

[0038] The elastic sealing block 33 elastically abuts against the control circuit board 32 and also elastically abuts against the wall of the docking groove 211 through the side cover 302. The elastic sealing block 33 is provided with a second docking hole 331 communicating with the first docking hole 212. The battery 34 is mounted on the mounting bracket 31. The airflow sensor 35 is located inside the second housing 30. The airflow sensor 35 is fixed on the control circuit board 32 and corresponds to the position of the elastic sealing block 33. The airflow sensor 35 communicates with the atomizing core 24 through the second docking hole 331 and the first docking hole 212. The electrode 36 is fixed at the side cover 302 and electrically connected to the control circuit board 32 and the atomizing core 24. The second magnet 37 is fixed at the side cover 302 and magnetically connected to the first magnet 16, thereby improving the reliability of the connection between the battery assembly 3, the atomizing assembly 2, and the oil cup assembly 1.

[0039] In summary, since the first end of the sealing plug 14 is inserted into the oil filling hole 121 and the second end of the sealing plug 14 abuts against the support seat 13, the sealing plug 14 is located within the space formed by the sealing seat 12 and the support seat 13. Therefore, after oil filling is completed and the sealing plug 14 is inserted into the oil filling hole 121, the sealing plug 14 cannot be removed, thus preventing repeated addition of e-liquid and eliminating the risk of arbitrarily injecting other unknown liquids. Furthermore, during the production process, before adding e-liquid, the sealing seat 12 is first inserted into one end of the first oil storage chamber 112, then the support seat 13 is inserted into the first positioning groove 123, and finally the e-liquid is added. This facilitates production and avoids the problem of production inconvenience caused by adding e-liquid too early.
