[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides an electronic cigarette, which includes a cartridge 1, an auxiliary oil cup 2, and a power supply component 3. The cartridge 1 includes a main oil storage component 11 and an atomizing core 12. The main oil storage component 11 includes a second receiving shell 111, a third sealing cap 112, and a ventilation tube 113. The second receiving shell 111 is provided with a connecting ring portion 1111 and a main oil storage chamber 1112. The connecting ring portion 1111 is located at the first end of the second receiving shell 111, and the first end of the second receiving shell 111 is positioned opposite to the second end of the second receiving shell 111.

[0023] The main oil storage chamber 1112 is used to store the first e-liquid. An absorbent cotton column 114 is housed within the main oil storage chamber 1112 to absorb the first e-liquid, thus locking it in and preventing excessive delivery. The main oil storage chamber 1112 is connected to the second end face of the second receiving shell 111, and a third sealing cap 112 is placed over the opening of the main oil storage chamber 1112. Preferably, the third sealing cap 112 can be made of an elastic material such as silicone or rubber, thus better sealing the e-liquid. The first end of the air vent 113 is connected to the third sealing cap 112, and the second end of the air vent 113 is inserted into the cartridge 1.

[0024] The atomizing core 12 is located within the main oil reservoir 1112 and installed at the air vent 113. It includes a porous absorber 121 and a heating element 122. The porous absorber 121 is installed at the air vent 113 and extends beyond it to absorb e-liquid within the main oil reservoir 1112. The absorbent cotton column 114 is in close contact with the porous absorber 121, thus effectively transferring e-liquid. The heating element 122 is in contact with the porous absorber 121 and atomizes the e-liquid within it. The vapor formed by the atomized e-liquid is discharged from the air vent 113. It is understood that the porous absorber 121 can be made of porous materials such as fiber or ceramic, and the heating element 122 can be a heating wire or a heating plate.

[0025] The secondary oil cup 2 includes a secondary oil storage component 21 and an oil control switch 22. The secondary oil storage component 21 includes a first receiving shell 211, a first sealing cap 212, a second sealing cap 213, and an elastic sealing seat 214. When upright, the first receiving shell 211 is located above the second receiving shell 111. The first receiving shell 211 is provided with a mouthpiece 2111, a secondary oil storage chamber 2112, and a clearance hole 2113. The air pipe 113 extends into the mouthpiece 2111, allowing the user to inhale vapor through the mouthpiece 2111. The secondary oil storage chamber 2112 is connected to the first end face of the first receiving shell 211 and is used to store a second e-liquid. The secondary oil storage chamber 2112 is located above the main oil storage chamber 1112, so when the oil control switch 22 is turned on, the e-liquid can be replenished by gravity flowing downwards.

[0026] It is understood that the second e-liquid can be the same as or different from the first e-liquid, and its composition is not specifically limited here. A first sealing cap 212 is affixed to the opening of the secondary e-liquid reservoir 2112. The first sealing cap 212 is provided with an e-liquid guiding cavity 2121, which communicates with both the main e-liquid reservoir 1112 and the secondary e-liquid reservoir 2112. The e-liquid guiding cavity 2121 is used to guide the e-liquid in the secondary e-liquid reservoir 2112 to the main e-liquid reservoir 1112. A connecting ring 1111 is inserted into and connected to the e-liquid guiding cavity 2121, thus improving the reliability of the connection. A second sealing cap 213 covers the opening of the clearance hole 2113. An elastic sealing seat 214 is located inside the secondary e-liquid reservoir 2112 and is used to seal the gap between the first sealing cap 212 and the first receiving shell 211. The second sealing cap 213 and the elastic sealing seat 214 can be made of materials such as silicone or rubber, thus providing good sealing performance.

[0027] The oil control switch 22 is partially inserted into the oil guiding cavity 2121 and extends to the outside of the auxiliary oil cup 2 via the clearance hole 2113. When the oil control switch 22 is turned on in the upright position, the second e-liquid in the auxiliary oil storage cavity 2112 flows into the main oil storage cavity 1112 due to gravity through the oil guiding cavity 2121. Specifically, the oil control switch 22 includes a limiting ring 221, an oil blocking element 222, a first sealing ring 223, a third sealing ring 224, a control rod 225, and an elastic element 226. The limiting ring 221 is mostly inserted into the oil guiding cavity 2121 and connected to the oil guiding cavity 2121. The outer peripheral surface of the limiting ring 221 is provided with a first limiting step 2211, which abuts against one end of the oil guiding cavity 2121 to prevent the limiting ring 221 from moving towards the main oil storage cavity 1112. Therefore, when the control lever 225 is pressed down, the limiting ring 221 is prevented from falling off, thus improving the reliability of the structure. The inner wall surface of the limiting ring 221 is provided with a second limiting step 2212.

[0028] The oil-blocking component 222 is located on the side of the limiting ring 221 facing the main oil reservoir 1112, to prevent the second e-liquid in the secondary oil reservoir 2112 from flowing into the main oil reservoir 1112 when the oil control switch 22 is closed. The oil-blocking component 222 has a first fixing groove 2221 on its end face facing the limiting ring 221, and a first sealing ring 223 is fixed in the first fixing groove 2221. When the oil control switch 22 is closed, the first sealing ring 223 elastically abuts against the end face of the oil-blocking component 222, thus better preventing the e-liquid in the secondary oil reservoir 2112 from flowing into the main oil reservoir 1112.

[0029] The third sealing ring 224 is fitted onto the outer circumferential surface of the limiting ring 221 and elastically abuts against the connecting ring portion 1111, thus preventing e-liquid leakage between the cartridge 1 and the auxiliary oil cup 2. The first end of the control rod 225 passes through the limiting ring 221 and is connected to the oil-blocking component 222. The second end of the control rod 225 extends to the outside of the auxiliary oil cup 2 via the clearance hole 2113. An oil-guiding gap 227 communicating with the auxiliary oil storage chamber 2112 is formed between the control rod 225 and the limiting ring 221. When the oil control switch 22 is closed, the oil-blocking component 222 covers the end face of the limiting ring 221 and one end of the oil-guiding gap 227.

[0030] The control lever 225 includes a connecting seat 2251, a lever body 2252, and a second sealing ring 2253. The connecting seat 2251 passes through the limiting ring 221 and is connected to the oil baffle 222. A third limiting step 22511 is provided on the outer peripheral surface of the connecting seat 2251. The first end of the lever body 2252 is connected to the connecting seat 2251, and the second end of the lever body 2252 extends to the outside of the auxiliary oil cup 2 via the clearance hole 2113. A third fixing groove 22521 is provided on the outer peripheral surface of the lever body 2252, and the second sealing ring 2253 is fixed in the third fixing groove 22521 and abuts against the wall of the clearance hole 2113.

[0031] The second sealing cap 213 is movably sleeved on the rod body 2252, thus effectively preventing e-liquid leakage.

[0032] The first end of the elastic element 226 abuts against the limiting ring 221, and the second end of the elastic element 226 abuts against the control rod 225 to drive the control rod 225 to move in the direction away from the main oil storage chamber 1112. The elastic element 226 can be a spring, a sheet, etc. In this embodiment, the elastic element 226 is a spring, the first end of the elastic element 226 abuts against the second limiting step 2212, and the second end of the elastic element 226 abuts against the third limiting step 22511. When the e-liquid in the main oil storage chamber 1112 is depleted, the user presses the rod 2252 of the oil control switch 22, causing the rod 2252 to move downwards. The oil-blocking member 222 disengages from the limiting ring 221, thus opening the oil control switch 22. The e-liquid in the secondary oil storage chamber 2112 flows into the main oil storage chamber 1112 due to gravity through the oil guide chamber 2121 and the oil guide gap 227. When the user stops pressing the oil control switch 22, the oil control switch 22 resets due to the elastic force of the elastic element 226. This method of refilling e-liquid is not only convenient for users, but also avoids the problem of e-liquid easily flowing out of the mouthpiece 2111 when the mouthpiece is inverted.

[0033] The power supply assembly 3 includes a connecting frame 31, a third receiving shell 32, a battery 33, and a control board 34. The first end of the connecting frame 31 is inserted into the main oil storage chamber 1112 and connected to the third sealing cover 112. The second end of the connecting frame 31 is connected to the third receiving shell 32. The battery 33 and the control board 34 are both located within the third receiving shell 32. The control board 34 is electrically connected to the battery 33 and the heating element 122 of the atomizing core 12. The control board 34 is equipped with a control circuit. When the user smokes, the control circuit controls the battery 33 to supply power to the heating element 122 of the atomizing core 12 to atomize the e-liquid.

[0034] In summary, this invention cleverly combines the e-liquid cartridge 1 and the auxiliary e-liquid cup 2. The cartridge 1 includes a main e-liquid storage component 11, which has a main e-liquid storage chamber 1112. The auxiliary e-liquid cup 2 includes an auxiliary e-liquid storage component 21 and an e-liquid control switch 22. The auxiliary e-liquid storage component 21 has a clearance hole 2113 and an auxiliary e-liquid storage chamber 2112 located above the main e-liquid storage chamber 1112. An e-liquid guiding chamber 2121 is provided between the main e-liquid storage chamber 1112 and the auxiliary e-liquid storage chamber 2112. The e-liquid control switch 22 is at least partially inserted into the e-liquid guiding chamber 2121 and extends to the outside of the auxiliary e-liquid cup 2 through the clearance hole 2113. When the e-liquid in the main e-liquid storage chamber 1112 is depleted, the user presses the e-liquid control switch 22 to open it. The e-liquid in the auxiliary e-liquid storage chamber 2112 flows into the main e-liquid storage chamber 1112 due to gravity through the e-liquid guiding chamber 2121. Therefore, it is not only environmentally friendly but also convenient for users. Furthermore, since the e-liquid automatically flows into the main oil storage chamber 1112 under gravity when the device is upright, the problem of e-liquid leakage when the device is upside down is better avoided, thus better preventing e-liquid leakage and users from inhaling e-liquid.
