Preferably, the cross-sectional area of the exhaust hole 1113 is smaller than the cross-sectional area of the oil injection hole 1112, thereby reducing the probability of leakage during use.

[0040] The main oil storage component 11 further includes an elastic sealing plug 17 and a suction nozzle 18. The elastic sealing plug 17 is located in the suction nozzle 18. The elastic sealing plug 17 covers the hole opening of the oil injection hole 1112 away from the main oil storage cavity 1111 and the hole opening of the exhaust hole 1113 away from the main oil storage cavity 1111, thereby better sealing the oil storage tube 111. The suction nozzle 18 is connected to the oil storage tube 111 and communicates with the breather tube 112. A user smokes through the suction nozzle 18. The first one-way valve 12 is installed at the first oil discharge hole 1114 to guide the second tobacco tar of the auxiliary oil cup 2 into the main oil storage cavity 1111 and prevent the first tobacco tar from flowing toward the auxiliary oil cup 2.

[0041] The first one-way valve 12 comprises a first fixed ring 121 and a first elastic valve body 122, the first fixed ring 121 is installed at the first oil outlet hole 1114, the first fixed ring 121 is a metal ring, thus being fixed stably, the first elastic valve body 122 is installed in the first fixed ring 121, the first elastic valve body 122 is provided with a first valve, the first valve is used for preventing the first tobacco tar from flowing outwards, the first elastic valve body 122 can be a silica gel valve body or a rubber valve body and the like, through cooperation of the first fixed ring 121 and the first elastic valve body 122, thus not only being connected stably, but also better avoiding oil leakage.

[0042] The atomizing core 13 is located in the main oil storage cavity 1111 and is used for atomizing the first tobacco tar, the atomizing core 13 comprises a porous elastic foam oil blocking pipe 131, a fixed pipe 132, a porous oil guiding sheet 133 and an electric heating element 134, the porous elastic foam oil blocking pipe 131 is located in the air pipe 112 and is sleeved outside the fixed pipe 132, the porous elastic foam oil blocking pipe 131 can be a polyurethane foam pipe and the like, a material thereof is not limited, as long as being made of a porous material with elasticity, and the porous elastic foam oil blocking pipe 131 can better seal the oil outlet hole 1121, the outer wall of the porous elastic foam oil blocking pipe 131 covers the oil outlet hole 1121, so as to block the first tobacco tar at the oil outlet hole 1121 from flowing into the fixed pipe 132 excessively, the bottom end of the fixed pipe 132 is connected with the sealing seat 13, and the side wall of the fixed pipe 132 is provided with an oil outlet hole 1321.

[0044] Since the porous elastic foam oil blocking pipe 131 is sleeved outside the fixed pipe 132, the outer wall of the porous elastic foam oil blocking pipe 131 covers the oil outlet hole 1121, so as to block the first tobacco tar at the oil outlet hole 1121 from flowing into the fixed pipe 132 excessively, and the porous oil guiding sheet 133 is spaced apart from the porous elastic foam oil blocking pipe 131, thus the porous elastic foam oil blocking pipe 131 itself can play a certain buffering role on the flow of the first tobacco tar, so as to reduce the flowability of the tobacco tar and slow down the speed of the first tobacco tar flowing into the porous oil guiding sheet 133.

[0045] Secondly, the porous elastic foam oil blocking tube 131 itself is provided with a plurality of microporous structures. When the tobacco tar passes through the microporous structures, an oil film is formed at the microporous structures. The surface tension of the oil film can further reduce the flowability of the tobacco tar, so that the speed of the first tobacco tar flowing into the porous oil guide sheet 133 is further slowed down, thereby effectively reducing the problem of "oil flying" of the atomizing core 13 caused by the tobacco tar flowing in too fast during the user's smoking.

[0046] The end face of the auxiliary oil cup 2 is provided with a third butt joint groove 201 extending in the transverse direction of the electronic cigarette, and the third butt joint groove 201 is provided with a first buckling convex 202.

[0053] In use, when the first e-liquid is exhausted, the electronic cigarette is inverted and the control rod 223 is pressed, so that the oil blocking piece 221 moves towards the direction away from the fixed cover 213, and the second oil outlet hole 2041 is opened, so that the electronic cigarette enters the second state. In the second state, the second e-liquid in the auxiliary oil storage cavity 203 flows into the oil guide cavity 204 through the third oil outlet hole 2042, and flows into the main oil storage cavity 1111 through the second one-way valve 23 in the second oil outlet hole 2041 and the first one-way valve 12 in the first oil outlet hole 1114, thereby realizing the replenishment of e-liquid. It can be understood that in the second state, the height of the position where the third oil outlet hole 2042 is located is lower than the height of the position where the second oil outlet hole 2041 is located.

[0054] By setting the limiting step 2043, the movement distance of the oil blocking piece 221 is limited, so that the control rod 223 is prevented from sinking into the oil guide cavity 204. After the replenishment of e-liquid is completed, the electronic cigarette is upright, and the user releases the control rod 223, so that the electronic cigarette is converted from the second state to the first state. In the process of converting the electronic cigarette from the second state to the first state, the oil blocking piece 221 moves towards the fixed cover 213 due to the elastic force of the spring 222, and returns to the original position. That is, in the second state, after the user stops applying force, the oil blocking piece 221 automatically returns to the original position to cover the hole of the second oil outlet hole 2041 due to the elastic force. Therefore, this structure has high reliability and avoids misalignment.
