[0023] Please refer to Figures 1-6This application provides an electronic cigarette, which includes an oil cup assembly 1, an atomizing assembly 2, and a battery assembly 3. The oil cup assembly 1 is detachably connected to the atomizing assembly 2 to provide e-liquid to the atomizing assembly 2. The oil cup assembly 1 includes an oil storage sleeve 11, a sealing seat 12, a support seat 13, and a limiting ring 14. One end of the oil storage sleeve 11 is provided with a smoke outlet 111, from which the smoke generated by the atomizing e-liquid of the atomizing assembly 2 is discharged. The oil storage sleeve 11 is provided with a main oil storage chamber 112, and a ventilation pipe 113 is provided in the main oil storage chamber 112. The ventilation pipe 113 communicates with the smoke outlet 111 to transport the smoke generated by the atomizing e-liquid of the atomizing assembly 2 to the smoke outlet 111.

[0024] The sealing seat 12 is movably inserted into one end of the main oil storage chamber 112, so that the e-liquid in the main oil storage chamber 112 can be squeezed into the atomizing assembly 2 under the action of external force. The sealing seat 12 is provided with a positioning groove 121 and an air guide hole 122, and the support seat 13 is partially inserted into the positioning groove 121. The air guide hole 122 is positioned corresponding to the air pipe section 113, and one end of the air pipe section 113 is inserted into the air guide hole 122 and they are interconnected. The limiting ring 14 is movably sleeved on the support seat 13 and connected to the oil storage sleeve 11. The support seat 13 and the limiting ring 14 form a mating groove 131, which is located at the end face of the oil cup assembly 1.

[0025] The groove wall of the docking slot 131 is provided with an oil outlet 132 for discharging e-liquid from the main oil storage chamber 112. A sealing piece 1321 is provided inside the oil outlet 132 to prevent e-liquid from flowing out of the main oil storage chamber 112. Before the oil cup assembly 1 is connected to the atomizing assembly 2, the sealing piece 1321 closes the oil outlet 132. After the oil cup assembly 1 is connected to the atomizing assembly 2, the sealing piece 1321 is punctured, allowing the oil outlet 132 to open.

[0026] Specifically, the support base 13 includes a first guide portion 134, a connecting portion 135, and a support plate portion 136. The first guide portion 134 is located on the outer wall surface of the support base 13, that is, the guide portion 134 is located on the outer surface of the connecting portion 135. The connecting portion 135 is annular and is connected to the support plate portion 136 and sleeved on the sealing seat 12. The end of the connecting portion 135 is inserted into the positioning groove 121. Therefore, the two are reliably and firmly connected together, the sealing seat 12 is not prone to tilting, and thus can better seal the e-liquid.

[0027] A limiting step 1351 is provided on the outer peripheral surface of the connecting part 135, and a limiting protrusion 141 and a second guide part 142 are provided on the inner wall surface of the limiting ring 14. The first guide part 134 and the second guide part 142 cooperate so that when the support seat 13 is subjected to the force of the atomizing component 2, the support seat 13 and the sealing seat 12 can move axially along the main oil storage chamber 112. In this embodiment, the first guide part 134 is a guide protrusion, and the second guide part 142 is a guide groove. The support plate part 136 is located at the end face of the sealing seat 12, and the support plate part 136 serves as part of the groove wall of the docking groove 131. The oil outlet hole 132 penetrates the sealing seat 12 and the support plate part 136, and extends longitudinally along the oil cup assembly 1.

[0028] The electronic cigarette of this application includes a first state and a second state. In the first state, the oil cup assembly 1 is separated from the atomizing assembly 2, and the limiting protrusion 141 abuts against the limiting step 1351 to prevent the support base 13 and the sealing seat 12 from moving outward from the oil reservoir sleeve 11. In the second state, the oil cup assembly 1 and the atomizing assembly 2 are connected together, the limiting protrusion 141 and the limiting step 1351 are spaced apart, and at least a portion of the area between the limiting ring 14 and the support base 13 forms a gap, thus facilitating the movement of the sealing seat 12 by the support base 13. It is understood that during the transition from the first state to the second state of the electronic cigarette, the sealing seat 12, together with the support base 13, moves from the first position to the second position.

[0029] The atomizing component 2 has an air guide ring 201, a docking ring 202, a leakage collection groove 203, an oil guide tube 204, and an exhaust tube 205 on its end face facing the oil cup component 1. In the second state, the air guide ring 201 is inserted into the air guide hole 122 to guide the vapor formed by the atomized e-liquid of the atomizing component 2 into the air vent tube 113. The outer peripheral surface of the air guide ring 201 is provided with a support step 2011. In the second state, the support step 2011 abuts against the support plate 136 to ensure that the support seat is evenly stressed and to better prevent oil leakage due to the misalignment of the sealing seat 12. The docking ring 202 is arranged around the air guide ring 201 and is inserted into the docking groove 131. The end face of the docking ring 202 faces the support plate 136 and is spaced apart from the support plate 136. The oil guide pipe 204 communicates with the main oil storage chamber 112 through the oil outlet hole 132 and through the sealing piece 1321.

[0030] The centerline of the atomizing component 2 passes through the airflow ring 201. When the e-cigarette is placed vertically with the outlet 111 facing upwards, the upper surface of the airflow ring 201 is higher than the upper surface of the docking ring 202, making assembly of the oil cup assembly 1 and the atomizing component 2 easier. The leakage collection groove 203 is located outside the docking ring 202, and the distance between the leakage collection groove 203 and the airflow ring 201 is greater than the distance between the docking ring 202 and the airflow ring 201. Therefore, the leakage collection groove 203 can collect e-liquid outside the docking ring 202. The wicking tube 204 and the exhaust tube 205 both extend through the sealing seat 12 into the main oil reservoir 112, and the e-liquid in the main oil reservoir 112 flows into the atomizing component 2 through the wicking tube 204. The distance between the smoke outlet 111 and the exhaust pipe 205 is less than the distance between the smoke outlet 111 and the oil guide pipe 204, thus improving exhaust performance.

[0031] One end of the atomizing component 2 is inserted into the battery assembly 3, while the other end is located outside the battery assembly 3. It includes an atomizing cup 21, a first porous oil-absorbing component 22, a second porous oil-absorbing component 23, an atomizing base 24, an atomizing coil 25, and a fixing base 26. The airflow ring 201, the docking ring 202, the leakage collection groove 203, the oil-guiding tube 204, and the exhaust pipe 205 are all located at the end face of the atomizing cup 21. The atomizing cup 21 contains a secondary oil storage chamber 211 and a leakage collection chamber 212. The secondary oil storage chamber 211 is located within the leakage collection chamber 212 and contains an absorbent cotton column 27. The absorbent cotton column 27 locks in the e-liquid, better preventing leakage. An air inlet 2111 and an oil outlet 2112 are provided on the wall of the auxiliary oil storage chamber 211. The air inlet 2111 is connected to the auxiliary oil storage chamber 211 and the exhaust pipe 205, so that gas can be discharged and oil can be easily introduced into the oil guide pipe 204.

[0032] The drain port 2112 is connected to the secondary oil storage chamber 211 and the oil guide tube 204. When the electronic cigarette is placed vertically and the smoke outlet 111 faces upward, the height of the air inlet 2111 is higher than the height of the drain port 2112, thus facilitating gas exhaust. In one embodiment, the air inlet 2111 and the drain port 2112 are located on opposite sides of the secondary oil storage chamber 211. The first porous oil-absorbing element 22 is located in the leakage collection chamber 212 to absorb leaked e-liquid. The second porous oil-absorbing element 23 is located in the space formed by the atomizing base 24 and the fixing base 26 to absorb condensed e-liquid. The first porous oil-absorbing element 22 and the second porous oil-absorbing element 23 can be porous materials such as cotton or ceramic.

[0033] The atomizer seat 24 is inserted into the opening of the leakage collection chamber 212 and covers the opening of the secondary oil storage chamber 211. The atomizer coil 25 is located in the secondary oil storage chamber 211 and inserted into the atomizer seat 24, used to atomize the e-liquid in the secondary oil storage chamber 211. The atomizer coil 25 contacts the absorbent cotton column 27 to absorb e-liquid from the absorbent cotton column 27. The fixing seat 26 covers the opening of the leakage collection chamber 212 and is sleeved on one end of the atomizer seat 24 to connect with the atomizer seat 24. The fixing seat 26 includes a cover plate portion 261, a first fixing portion 262, and a second fixing portion 263. The cover plate portion 261 covers the opening of the leakage collection chamber 212. The first fixing portion 262 is located on the side of the cover plate portion 261 facing the leakage collection chamber 212 and is connected to the cover plate portion 261 and the cavity wall of the leakage collection chamber 212. The second fixing part 263 is located on the side of the cover plate part 261 facing the leakage receiving cavity 212, and is connected to the cover plate part 261 and the atomizing seat 24. Preferably, both the first fixing part 262 and the second fixing part 263 are annular, which can increase the sealing performance of the atomizing seat 24.

[0034] Battery assembly 3 is connected to atomizing assembly 2 and includes a battery sleeve 31, a mounting bracket 32, a control board 33, an airflow sensor 34, and a battery 35. One end of atomizing assembly 2 is inserted into the battery sleeve 31. The mounting bracket 32 ​​is located inside the battery holder 35 and abuts against the mounting base 26 of atomizing assembly 2. The control board 33 is fixed to the mounting bracket 32 ​​and electrically connected to the atomizing coil 25 to control the operation of the atomizing coil 25. The airflow sensor 34 is fixed to the control board 33 and is used to sense the user's smoking action. The battery 35 is located inside the battery sleeve 31 and electrically connected to the control board 33 to provide power.

[0035] In summary, because the atomizing component 2 has a docking ring 202, a leakage collection groove 203, and an oil guide tube 204 on its end face facing the oil cup component 1, and the leakage collection groove 203 is located outside the docking ring 202, in the first state the oil cup component 1 and the atomizing component 2 are separated, and in the second state the docking ring 202 is inserted into the docking groove 131, and the oil guide tube 204 communicates with the main oil storage chamber 112 through the oil outlet 132 and through the sealing plate. Therefore, leaked e-liquid easily flows into the leakage collection groove 203. Compared with the prior art, this utility model better prevents e-liquid from leaking out from the connection between the oil cup component 1 and the atomizing component 2.
