An oil seal member shown in fig. 4 is installed in the partition passage 53, and the oil seal member is movable in the partition passage 53 in the axial direction of the partition passage 53, and is used for blocking or opening the communication between the first portion 521 and the second portion 522 and preventing the atomized oil in the oil storage chamber 13 from leaking out of the partition passage 53. The seal body 1 of the oil seal is in interference fit with the separation channel 53. The material of the sealing element main body 1 is hard glue material.

The first sealing part 1a and the second sealing part 1c are respectively located at two ends of the separation channel 53, and the first sealing part 1a is located between the first part 521 and the second part 522 so as to block the communication between the first part 521 and the second part 522, so that the atomizing oil in the oil storage cavity 13 can be prevented from entering the oil inlet hole 311 through the oil inlet channel 52, and the effect of isolating the atomizing oil from the atomizing core 30 is achieved, even if the atomizer is transported for a long distance, carried or placed for a long time, the atomizing oil can not enter the oil inlet hole 311, so that the atomizing oil can not be accumulated on the heating body 32, and the oil leakage phenomenon can not occur, therefore, a user can have better suction experience when the atomizer is used for the first time.

The first sealing portion 1a is located between the first portion 521 and the second portion 522, and the atomized oil flowing into the partition passage 53 from the oil storage chamber 13 can be stored through the plurality of oil storage spaces 5 on the outer periphery of the first end 2a of the first sealing portion 1a, so that the oil seal member also plays a role of preventing the atomized oil from leaking from the partition passage 53, and the partition passage 53 can be sealed. The oil storage concave position 6 arranged at the bottom of the oil storage space 5 can further prevent the atomized oil from leaking out of the separation channel 53.

The second sealing portion 1c is used to seal the far end of the partition passage 53, and can prevent water, dust, etc. from entering the partition passage 53 from the protective sleeve through hole 41 and the through hole 21.

When the user uses the heating element 32 for the first time, the oil seal member can be moved along the partition passage 53 to a position where the communication portion 1b is located between the first portion 521 and the second portion 522, as shown in fig. 12, so that the communication portion 1b can open the communication between the first portion 521 and the second portion 522, at this time, the atomized oil in the oil storage chamber 13 can enter the oil inlet hole 311 through the oil inlet passage 52 and enter the heating element 32, so as to be heated and atomized into gas by the heating element 32. The movement of the oil seal to the position where the communication portion 1b is located between the first portion 521 and the second portion 522 can be performed by an auxiliary tool such as a tubular object equipped with the atomizer or the like, specifically, one end of the tubular object is extended into the through hole 21 from the protective sleeve through hole 41, and the oil seal is pushed upward with force until the communication portion 1b of the oil seal is located between the first portion 521 and the second portion 522, and at this time, the user can use the oil seal. For the convenience of observation of a user, the oil cup 10 and the atomizing base 50 can be transparent, and when the first sealing part 1a of the oil seal is almost completely positioned in the oil storage cavity 13, the oil seal can be stopped being pushed, and the atomizer can be used at the moment. When the first seal portion 1a is located in the oil reservoir chamber 13, the atomized oil in the oil reservoir chamber 13 can also enter the second portion 522 from the partition passage 53.

In the present embodiment, the outer diameters of the first seal portion 1a and the second seal portion 1c are larger than the inner diameter of the partition passage 53 to play a role of blocking the communication between the first portion 521 and the second portion 522 and a role of sealing the partition passage 53.

The communication portion 1b has an outer diameter smaller than an inner diameter of the partition passage 53 to function to open between the first portion 521 and the second portion 522. The lengths of the first sealing portion 1a, the second sealing portion 1c and the communicating portion 1b are all larger than the inner diameter of the oil inlet passage 52, so that the first sealing portion 1a and the communicating portion 1b can function as a blocking or opening when located between the first portion 521 and the second portion 522, respectively.

In this embodiment, two oil inlet channels 52 communicated with the oil storage cavity 13 are respectively disposed on two sides of the upper end of the atomizing base 50, that is, two oil inlet channels 52 can increase the oil inlet amount, so that two sides of the upper end of the atomizing base 50 are respectively provided with the slot 51, the atomizing base 50 is provided with two separating channels 53, and the two separating channels 53 are respectively disposed on two sides of the atomizing base 50. The first end of the atomizing tube 31 has oil inlet holes 311 respectively communicating with the two oil inlet passages 52. The number of the oil seal members is also two. That is, the number of the oil inlet passages 52, the partition passages 53, the oil inlet holes 311, and the oil seal members is the same.

In other embodiments, the number of the oil inlet passage 52, the partition passage 53, the oil inlet hole 311 and the oil seal may also be, for example, three or more than four, and may be set according to actual conditions.

In an alternative of the oil seal, as shown in fig. 13, the oil seal is based on the oil seal shown in fig. 1, and a through hole 7 for communicating the first portion 521 and the second portion 522 is provided in the seal main body 1 shown in fig. 1. The through hole 7 is located below the first and second portions 521 and 522, so that the communication between the first and second portions 521 and 522 is blocked and the atomized oil in the oil storage chamber 13 is prevented from leaking out of the partition passage 53. When the user uses the oil seal for the first time, the oil seal sealing member can be moved to the position where the through hole 7 is located between the first part 521 and the second part 522, and at this time, the communication part 1b can open the communication between the first part 521 and the second part 522 through the through hole 7, so that the atomized oil in the oil storage chamber 13 can enter the oil inlet hole 311 through the oil inlet passage 52 and finally enter the heating body 32. In actual use, the oil seal may be pushed up by the tubular member until the through hole 7 of the communicating portion 1b is located between the first portion 521 and the second portion 522. The oil cup 10 and the atomizing base 50 can be transparent, so that the moving position can be conveniently observed.

The inner diameter of the through hole 21 of the electrode base 20 is smaller than the inner diameter of the partition passage 53 so as to limit the movement of the oil seal, that is, the communicating portion 1b of the oil seal can be located between the first portion 521 and the second portion 522 only by pushing the oil seal upward, and the oil seal cannot be pulled downward.
