Inside the atomizing assembly 1, the electrode 17 is electrically connected to the atomizing core 16 through a lead 17. The electrodes 18 are at least two, i.e., a positive electrode for supplying a positive voltage to the atomizing core 16 and a negative electrode for supplying a negative voltage to the atomizing core 16.

And the bottom wall 121 is located at the periphery of the elastic sealing plug 15 and lifts the elastic sealing plug 15 upward.

In a further embodiment, the thickness of the bottom cover 12 is not greater than the thickness of the first housing 11. When at least part of the surrounding wall 122 is located inside the first housing 11, the thinner thickness of the bottom cover 12 can reduce the occupation of the surrounding wall 122 to the space inside the first housing 11; a thinner thickness of the bottom cover 12 may help to reduce the overall weight of the atomization assembly 1 when at least a portion of the surrounding wall 122 is located at the periphery of the first housing 11. In one embodiment, the bottom cover 12 is made entirely of metal, so that the bottom cover 12 has greater strength, allowing it to be thinner.

The first through hole 124 and the second through hole 125 are independent of each other, spaced from each other, and not communicated with each other, so as to help enlarge the area of the magnetic attraction portion 1211, and increase the area of the magnetic attraction portion 1211, which helps to increase the magnetic attraction force between the atomization assembly 1 and the power supply assembly 2, so that the connection between the atomization assembly 1 and the power supply assembly 2 is more stable, and at the same time, helps to ensure the reliability of the electrical connection between the electrode 18 and the electrical connection member 23. To further increase the area of the magnetic attraction 1211, the aperture of the first through hole 124 may be smaller than that of the air flow channel 153.

In the embodiment shown in fig. 4, the tube wall of the nebulizing tube 14 is provided with at least one notch 141, through which notch 141 the nebulizing wick 16 is in contact with the aerosol substrate in the reservoir.

The heating element 162 is positioned on the porous core 161, for example, the heating element 162 may be a heating coil or a heating net, etc. wound or sleeved on the porous core 161. A portion of the porous wick 161 passes through the notch 141 into the reservoir to contact the aerosol substrate, and the lead wire 17 is electrically connected to the heat-generating body 162 to supply power to the heat-generating body 162 for joule heating, as shown in fig. 5, at least a portion of the heat-generating body 162 being located inside the nebulizing tube 14 such that nebulization of the aerosol substrate occurs in the nebulizing tube 14, whereupon aerosol is formed in the nebulizing tube 14 and then passes through the nebulizing tube 14 into the mouthpiece 13 as drawn by the user.

The aerosol in the atomizing tube 14 and/or the suction nozzle 14 forms condensate when it cools during the flowing process in the atomizing assembly 1, and the condensate adheres to the inner wall of the atomizing tube 14 and/or the suction nozzle 13, and the condensate flows downwards along the atomizing tube 14 and the air flow channel 153 under the action of gravity as the condensate increases, and in order to prevent the condensate from leaking, a liquid suction element 19 is arranged, and the condensate is sucked by the liquid suction element 19. In fig. 4 and 5, the liquid absorbing member 19 is disposed in the air flow passage 153, but not limited thereto.

Referring to fig. 4 and 5, the liquid absorbing member 19 may be a liquid absorbing cotton having air passing holes 191 defined therein to allow gas to pass therethrough, and the liquid absorbing member 19 may be in close contact with the walls of the gas flow passage 153 to absorb condensate flowing down the walls of the gas flow passage 153, thereby preventing the condensate from entering the first through holes 124 and flowing out. When the mouthpiece 13 is sucked, the air enters the atomizing assembly 1 through the first through hole 124, passes through the air hole 191 and the air flow passage 153, enters the atomizing pipe 14, forms an aerosol together with the aerosol substrate atomized by the atomizing core 16, and finally enters the mouthpiece 13 to be sucked.

To ensure stability, the two notches 141 may be symmetrically arranged, and the porous core 161 has a bar shape or a rod shape, and two opposite ends of the porous core enter the storage bin through the two notches 141 respectively.

Referring to fig. 5, the atomizing core 16 is located higher than the bottom of the storage bin, in order to fully utilize the aerosol substrate in the storage bin, so that the aerosol substrate at the bottom of the storage bin can also be adsorbed by the porous core 161 and then transferred to be atomized by the heating element 162, the storage bin can be filled with the liquid storage medium 3, the aerosol substrate is stored through the liquid storage medium 3, and the part of the porous core 161 extending into the storage bin abuts against the liquid storage medium 3 to adsorb the aerosol substrate from the liquid storage medium 3, so that the aerosol substrate at the bottom of the storage bin can also be transferred to the porous core 161.

In the embodiment shown in fig. 6, the atomizing pipe 14 is opened with an air flow port 142, and the air flow port 142 communicates with the inside of the atomizing pipe 14 and the storage bin. On one hand, when the gas, the liquid storage medium 3 and/or the aerosol substrate in the storage bin expand under the condition that the heating element 162 generates heat, the air pressure in the storage bin is increased, and part of air in the storage bin can be discharged into the atomizing pipe 14 through the air flow port 142, so that the air pressure inside and outside the storage bin is balanced; alternatively, on the other hand, as the aerosol substrate is consumed, the air pressure in the reservoir decreases, affecting the rate at which the porous wick 161 absorbs the aerosol substrate, and the gas in the nebulizing tube 14 can enter the reservoir through the gas flow port 143, balancing the air pressure inside and outside the reservoir.

Referring to fig. 6, the air flow opening 142 may include a slit, and of course, the air flow opening 142 may also include a round hole or a square hole.
