In other words, when the suction nozzle 190 is pressed, the first step surface 105 of the first step portion 103 can limit the moving distance of the suction nozzle 190 relative to the sump assembly 160 along the height direction of the atomizer 150, so as to avoid the influence on the reliability of the use of the atomizing core assembly 180 due to the excessive moving distance of the suction nozzle 190 relative to the sump assembly 160.

At least a portion of the suction nozzle 190 is exposed relative to the sump assembly 160, so that a user can lift and press the suction nozzle 190 when using the electronic cigarette 100, so that the suction nozzle 190 moves between the first position and the second position, and further, the atomizing core assembly 180 is driven to move relative to the sump assembly 160 along the height direction of the atomizer 150. Illustratively, the suction nozzle 190 is sleeved over the end of the main tube portion 42 remote from the flange portion 41 by a staking process to provide a rigid connection between the suction nozzle 190 and the center tube 40.

The two second magnets 170 are mounted to the two second mounting holes 202 of the sump base 20, respectively. Illustratively, two second magnets 170 may be attached to the sump base 20 by staking. The two second magnets 170 are magnetically attracted to the two first magnets 130, so as to improve the assembly stability between the atomizer 150 and the housing 110 and the bracket 120, and further improve the structural stability of the electronic cigarette 100. It should be noted that, in other embodiments, the first magnet 130 may have one or more than three, and the second magnet 170 may have one or more than three, where one first magnet 130 and one second magnet 170 magnetically attract each other.

It is to be understood that the polarities of the first magnet 130 and the second magnet 170 that are magnetically attracted to each other are opposite, for example, the polarities of the two first magnets 130 are N poles, the polarities of the two second magnets 170 are S poles, or the polarities of the two first magnets 130 are S poles, the polarities of the two second magnets 170 are N poles, or the polarities of one first magnet 130 are N poles, the polarities of the other first magnet 130 are S poles, the polarities of one second magnet 170 are N poles, the polarities of the other second magnet 170 are S poles, the polarities of the first magnet 130 with the N pole are magnetically attracted to the second magnet 170 with the S pole, and the polarities of the first magnet 130 with the S pole are magnetically attracted to the second magnet 170 with the N pole.

As shown in fig. 4, when the electronic cigarette 100 is in the unused state, the atomizer 150 is in the separated state, the suction nozzle 190 is in the first position, the two oil inlet holes 401 of the central tube 40 and the two oil outlet holes 163 of the oil sump seal 30 are offset from each other, the central tube 40 is disposed at intervals from the first electrode 141 and the electrode nails 50 are disposed at intervals from the second electrode 142 along the height direction of the electronic cigarette 100. Wherein the flange portion 41 of the center tube 40 abuts the second step surface 205 of the second step portion 203.

It can be appreciated that when the suction nozzle 190 is lifted, the second step surface 205 of the second step portion 203 can limit the moving distance of the central tube 40 relative to the sump assembly 160 along the height direction of the atomizer 150, that is, limit the moving distance of the atomizing core assembly 180 relative to the sump assembly 160, so as to avoid that the moving distance of the atomizing core assembly 180 relative to the sump assembly 160 is too large to affect the use reliability of the atomizing core assembly 180.

In other words, when the electronic cigarette 100 is in the unused state, the atomization core component 180 is completely separated from the oil storage cavity 162, so that the flow path of the tobacco tar in the oil storage cavity 162 is cut off, the tobacco tar in the oil storage cavity 162 is prevented from flowing out through the oil inlet 401, and the risk of oil leakage when the electronic cigarette 100 is in the unused state is reduced. Moreover, when the electronic cigarette 100 is in an unused state, the central tube 40 and the electrode nails 50 are arranged at intervals with the two electrodes 140, so that the connection between the atomizing core assembly 180 and the internal circuit of the electronic cigarette 100 is disconnected, and the phenomenon that the atomizing core assembly 180 burns dry and burns paste when the electronic cigarette is triggered by mistake is avoided, and the suction of children can be prevented to a certain extent.

As shown in fig. 5, when the electronic cigarette 100 is in a use state, the atomizer 150 is in a combined state, the suction nozzle 190 is in a second position, two oil inlet holes 401 of the central tube 40 are respectively communicated with two oil outlet holes 163 of the oil bin sealing member 30, tobacco tar in the oil storage cavity 162 can reach the heating member 70 through the two oil outlet holes 163 and the two oil inlet holes 401, the central tube 40 is in contact with the first electrode 141 to form effective connection, the electrode nail 50 is in contact with the second electrode 142 to form effective connection, and contact between the atomizing core component 180 and the two electrodes 140 is realized to be triggered. Wherein the flange portion 41 of the center tube 40 is spaced apart from the second step surface 205 of the second step portion 203 in the height direction of the atomizer 150.

It can be appreciated that, since the first electrode 141 and the second electrode 142 have elasticity, when the central tube 40 contacts the first electrode 141 and the electrode nail 50 contacts the second electrode 142, the first electrode 141 can buffer the acting force of the central tube 40, and the second electrode 142 can buffer the acting force of the electrode nail 50, so that the atomizing core assembly 180 is prevented from being damaged due to rigid contact with the first electrode 141 and the second electrode 142, and the reliability of use of the atomizing core assembly 180 is ensured.

The procedure of switching the electronic cigarette 100 between the unused state and the used state in this embodiment is as follows:

when the electronic cigarette 100 is switched from the unused state to the used state, the smoke and oil in the oil storage cavity 162 sequentially pass through the two oil outlet holes 163 and the two oil inlet holes 401 to reach the heating element 70 by pressing the suction nozzle 190, meanwhile, the central tube 40 is contacted with the first electrode 141, the electrode nail 50 is contacted with the second electrode 142, the atomization core assembly 180 is formed to be contacted with the two electrodes 140 to be triggered, and the suction is realized by suction or key triggering.

When the electronic cigarette 100 is switched from the use state to the non-use state, the two oil inlet holes 401 of the central tube 40 and the two oil inlet holes 401 of the oil bin sealing member 30 are mutually staggered through the lifting suction nozzle 190, the two oil inlet holes 401 of the central tube 40 are wrapped by the oil bin sealing member 30, and tobacco tar in the oil storage cavity 162 cannot flow into the heating member 70, so that the atomization core component 180 and the oil storage cavity 162 are completely separated. Since neither the center tube 40 nor the electrode pins 50 are in contact with the two electrodes 140, the atomizing core assembly 180 is disconnected from the internal circuit of the electronic cigarette 100, thereby protecting the atomizing core assembly 180 from dry combustion. Also, in this state, the suction cannot trigger the atomizer 150, and the child can be prevented from sucking to some extent.

In the electronic cigarette 100 shown in this embodiment, the atomizing core component 180 can be driven to move relative to the oil bin component 160 by lifting or pressing the suction nozzle 190 at any time in use, so as to separate the atomizing core component 180 from the oil storage cavity 162 and disconnect the triggering connection existing between the atomizing core component 180 and the internal circuit of the electronic cigarette 100, and the electronic cigarette is simple in operation and convenient to switch between an unused state and a use state. When the electronic cigarette 100 is in an unused state, the risk of oil leakage of the electronic cigarette 100 can be reduced, burning during false triggering can be prevented, and the use experience of a user is improved.
