In the width direction of the atomizing assembly 2, the oil inlet 212 is spaced from the stepped structure 211 by a certain distance, so that the path of the atomized liquid entering the oil inlet 212 can be properly prolonged, a certain buffer path still exists after the atomized liquid passes through the stepped structure 211, and the atomized liquid flows to the atomizing cavity through the oil inlet 212, so that the atomized liquid can be further ensured to be fully absorbed and atomized by the heating assembly 23 in the atomizing cavity 22, and the user experience can be further improved.

Further, the partition structure 24 is provided with a oil-penetration groove 241 communicated with the adjacent oil-discharging channel, and the oil-penetration groove 241 is located above the oil inlet 212. Specifically, since the separation structure 24 is long and extends from the top side of the atomizing assembly 2 to the bottom side of the atomizing assembly 2, the oil-stringing groove 241 is arranged on the separation structure 24, which can achieve the purpose of communicating adjacent oil-down channels, and the environments of the adjacent oil-down channels are consistent, so as to keep the oil-down consistency of the adjacent oil-down channels 21, thereby keeping the oil-down balance of each oil-down channel, improving the service efficiency of the atomizer, and enabling each oil-down channel to work synchronously. And the oil-mixing groove 241 should be disposed above the oil inlet 212, if the oil-mixing groove 241 is disposed at the connection portion of the partition structure 24 and the oil inlet 212, the oil-mixing groove 241 may interfere the flow direction and flow velocity of the atomized liquid to the oil inlet 212, so that a liquid leakage phenomenon may occur. Further, the size of the oil-mixing groove 241 should be small enough to be far smaller than or equal to the size of one bubble, so that the bubbles generated by the atomizing assembly 2 cannot pass through the oil-mixing groove 241, and even if the bubbles enter the oil-mixing groove 241, the bubbles can only be blocked in the oil-mixing groove 241 and cannot go out, and when the bubbles are blocked in the oil-mixing groove 241, two adjacent oil-discharging channels are completely separated to discharge oil.

Further, the outer side of the atomizing assembly 2 further comprises a transition groove 25 arranged at the top of the lower oil groove 21, the step structure 211 is connected to the bottom of the transition groove 25, the transition grooves 25 are arranged at intervals and are all communicated with the oil storage bin 11, and the lower oil groove 21 is communicated with the oil storage bin 11 through the transition groove 25. Specifically, the tank bottom of the transition tank 25 is perpendicular to the central axis of the atomizer, the transition tank 25 corresponds to the lower oil tank 21 one by one, the lower oil tank 21 can be communicated with the oil storage bin 11 through the transition tank 25, so that in the process of discharging oil, atomized liquid firstly enters the transition tank 25 from the oil storage bin 11, then enters the lower oil tank 21 from the transition tank 25, enters the oil inlet hole 212, is absorbed by the heating component 23 in the atomizing cavity 22, is heated and atomized, and finally forms aerosol. Through separating into a plurality of transition grooves 25, correspond the transition groove 25 with lower oil groove 21 again to when the in-process of atomising liquid down flow, the flow of atomising liquid can be hindered, thereby the mobility of atomising liquid at transition groove 25 and lower oil groove 21 will be variation, can produce the effect that slows down the velocity of flow of atomising liquid, and then can prevent the weeping.

Further, the atomizing assembly 2 further comprises a first air outlet 26 communicated with the atomizing chamber 22, and the first air outlet 26 is used for isolating each transition groove 25; the oil cup 1 includes a second air outlet 12 in communication with a first air outlet 26. Specifically, the atomizer further includes a suction nozzle disposed at a side of the oil cup 1 away from the atomizing assembly 2, and the suction nozzle is provided with the second air outlet 12, so that the aerosol formed in the atomizing chamber 22 can sequentially pass through the first air outlet 26 and the second air outlet 12 for the user to suck.

Further, since the first air outlet 26 is provided in the shape of an annular groove, when liquid leakage or condensate flows to the first air outlet 26, the liquid leakage or condensate can be stored in the annular groove, so that the sealing structure of the oil cup 1 and the atomizing assembly 2 at the air outlet can be saved, materials can be reduced, and production cost can be reduced.

Further, the stepped structure 211 includes a first inclined stepped surface 2111 connected to one side of the transition groove 25, and the first inclined stepped surface 2111, the first air outlet 26 and the inner wall of the cup 1 form a first oil discharging space having a cross-sectional area that gradually expands from the top side toward the bottom side.

Specifically, on one hand, the ventilation channel 27 may be communicated with the lower oil groove 21, and the lower oil groove 21 is further communicated with the oil storage bin 11 through the transition groove 25; alternatively, the ventilation channel 27 may be in direct communication with the oil reservoir 11 without passing through the lower oil sump 21; on the other hand, the ventilation channel 27 is communicated with the atomization cavity 22, and the atomization cavity 22 is communicated with the outside atmosphere, so that the gas source of the ventilation channel 27 can come from the atomization cavity 22, and the air pressure of the oil storage bin 11 can be balanced through the ventilation channel 27, so that atomized liquid in the oil storage bin 11 can smoothly flow downwards; because the ventilation channel 27 is at least partially connected with the heating component 23, when liquid leakage exists in the ventilation channel 27, the liquid leakage can be directly absorbed by the heating component 23, so that on one hand, the liquid leakage can be effectively prevented, and on the other hand, the ventilation channel 27 can always keep a clean state without liquid leakage blocking, and further, the ventilation channel 27 can realize smooth ventilation, and the gas-liquid balance of the oil storage bin 11 can be better realized.

Further, the step structure 211 further includes a guide step surface 2112 connected to the bottom side of the first inclined step surface 2111, and a vertical step surface 2113 provided at the bottom side of the guide step surface 2112 and perpendicular to the central axis of the atomizer; the ventilation passage 27 includes a ventilation hole 271 formed in the vertical step surface 2113, and a ventilation structure extending from the ventilation hole 271 to the bottom of the atomizing assembly 2.

Specifically, the vertical step surface 2113 is perpendicular to the central axis of the atomizer, and the ventilation hole 271 is provided on the vertical step surface 2113, so that when the atomizer is ventilating, the gas flows from the ventilating structure to the ventilation hole 271 and then flows out of the ventilation hole 271, it can be directly raised. The guide stepped surface 2112 is located above the vertical stepped surface 2113, and therefore, the gas should flow to the guide stepped surface 2112 after exiting from the ventilation hole 271. In this embodiment, the guiding step surface 2112 may be perpendicular to the perpendicular step surface 2113, so that after the gas comes out from the ventilation hole 271, the guiding step surface 2112 may perform a gas guiding function, so that the gas may rise straight, during the rising process, the bubbles may overflow normally (because the ventilation hole 271 is disposed at the oil drainage channel, the ventilation gas may contact the atomized liquid), and finally the gas may smoothly flow into the oil storage bin 11 to balance the air pressure of the oil storage bin 11. In other embodiments, the guide step surface 2112 may be disposed at an obtuse angle relative to the vertical step surface 2113, as well as to ensure proper bubble overflow.

Further, the ventilation structure comprises a ventilation groove 272 which is arranged on one side of the atomizing assembly 2 close to the atomizing cavity 22 and is connected with the ventilation hole 271, the ventilation groove 272 and the oil inlet 212 are arranged at intervals, and the heating assembly 23 covers the ventilation groove 272 and the oil inlet 212. Specifically, the ventilation groove 272 is opened towards the atomization cavity 22, and the ventilation groove 272 extends from the bottom side of the atomization component 2 towards the ventilation hole 271, so that the gas of the ventilation groove 272 comes from the atomization cavity 22 on one hand, and the gas of the atomization cavity 22 can flow to the ventilation groove 272 through the oil cotton (the oil cotton is a porous material) of the heating component 23; on the other hand, the outside atmosphere may flow directly through the bottom of the ventilation groove 272 to the ventilation groove 272. The oil inlet 212 and the ventilation groove 272 are arranged at intervals, so that the oil inlet process and the ventilation process can be independently carried out and are not mutually interfered, and the normal oil inlet and normal ventilation of the atomizer are ensured.

Specifically, the second oil draining space is the bottom part of the oil draining channel, and since the second inclined step surface 2114 extends obliquely downwards from the side of the vertical step surface 2113, the second inclined step surface 2114, the partition structure 24 and the inner wall of the oil cup 1 form the second oil draining space, and the oil inlet 212 is located in the second oil draining space; the air vent 271 is disposed on the vertical step surface 2113, so that the oil inlet 212 and the air vent 271 are disposed at intervals, the air vent 271 is disposed above the oil inlet 212, and the heating element 23 covers the oil inlet 212 and the air vent 272, that is, the oil guide cotton of the heating element 23 covers the oil inlet 212 and the air vent 272, when the oil guide cotton is pressed to cover the oil inlet 212 and the air vent 272, the oil guide cotton is pressed to cover the space between the oil inlet 212 and the air vent 272 (the two are disposed at intervals, and have a distance space therebetween), so that atomized liquid flowing through the oil inlet 212 and gas ventilated in the air vent 272 will not interfere with each other, the atomized liquid will not flow to the air vent 272, (the atomized liquid is directly absorbed by the oil guide cotton, and is directly heated and atomized by the heating element of the heating element 23), and the gas will not flow to the oil inlet 212, thereby preventing the problem of air blocking at the oil inlet 212, and ensuring smooth oil inlet (without air blocking the oil inlet 212). In addition, the oil inlet 212 is disposed between the second inclined step surface 2114 and the partition structure 24, and the second inclined step surface 2114 faces the partition structure 24, the cross-sectional area of the second oil down space is gradually reduced from top to bottom, and the second oil down space is the bottom portion of the oil down channel, so that the atomized liquid in the oil storage bin 11 is not directly flushed into the oil inlet 212 due to the structure of the top portion of the oil down channel to fully limit the flow rate of the atomized liquid, and thus the atomized liquid is directly led into the oil guiding body, but the situation that the heating assembly 23 burns dry is prevented, so that the second oil down space with the cross-sectional area gradually reduced from top to bottom can be disposed at the bottom portion of the oil down groove 21, the gradually reduced amplitude can be controlled according to the actual situation, so that the oil inlet speed of the atomized liquid can be properly adjusted, and the air exchanging action of the atomized liquid to the top portion of the oil down groove 21 can be avoided to a certain extent.

Further, the atomizing assembly 2 comprises a support, the oil cup 1 is sleeved outside the support, two lower oil grooves 21 are formed in the outer side of the support at intervals, two lower oil passages are formed between the support and the oil cup 1 at intervals, and an atomizing cavity 22 is formed in the support.

The oil cup 1 is sleeved on the outer side of the atomization assembly 2, and the oil cup 1 is provided with the oil storage bin 11, so that atomized liquid possibly leaks between the inner wall of the oil cup 1 and the outer side of the bracket, and if the leaked liquid continuously flows downwards to the battery assembly, the battery assembly is damaged; therefore, a plurality of oil storage bins are arranged on the outer side of the support, and leakage can flow to the oil storage bins, so that leakage can be effectively prevented from flowing to the battery assembly. Further, the outer side of the support is also provided with a yielding groove, the atomizer further comprises a sealing ring, the inner side of the sealing ring is abutted to the yielding groove, and the outer side of the sealing ring is abutted to the inner wall of the oil cup 1.
