In some embodiments, the axial length of the sleeve portion 321 may be greater than or equal to the distance between the end of the upper base 212 of the atomizing base 21 and the bottom of the liquid supply hole 2111, so that the liquid supply hole 2111 is blocked when the liquid inlet pipe 32 moves to the first position, and the liquid supply hole 2111 and the liquid storage cavity 13 are blocked, so that the atomizing core 22 is blocked from the liquid storage cavity 13.

In some embodiments, the inlet tube 32 includes an insert portion 322, the insert portion 322 being movably inserted into the sealing connection 31, and in particular, the insert portion 322 being movably inserted into the channel 313. The wall of the liquid inlet pipe 32 is provided with a liquid inlet 3221, specifically, the liquid inlet 3221 may be located on a side wall of the embedded portion 322, that is, a section of the liquid inlet pipe 32 provided with the liquid inlet 3221 is movably inserted into the channel 313. In some embodiments, the insertion portion 322 may be a hollow structure having a plug opening 3223 disposed near one end of the air outlet 14, so as to facilitate insertion of the priming device 2 into the insertion opening 3223 disposed near the air outlet 14. The lateral dimension of the insert 322 may be smaller than the lateral dimension of the channel 313 and may thus facilitate axial movement along the channel 313. Specifically, in some embodiments, the insert 322 has a maximum radial dimension, the channel 313 may be circular in cross-section, and the maximum radial dimension of the insert 322 may be less than the radial dimension of the channel 313. The liquid inlet 3221 may form part of the liquid inlet channel 40, and when the liquid inlet pipe 32 moves to the first position, that is, the liquid inlet 3221 moves at least partially to the outside of the channel 313, the liquid inlet 3221 communicates with the liquid storage cavity 13; when one end of the liquid inlet pipe 32 is at the second position, that is, the liquid inlet 3221 is located entirely inside the channel 313, the liquid inlet 3221 is isolated from the liquid storage cavity 13 by the side wall of the sealing connection member 31. In some embodiments, at least one side of the embedded portion 322 is provided with a tangential plane 3222, specifically, the tangential plane 3222 is disposed on two opposite sides of the embedded portion 322, and by providing the tangential plane 3222, a gap is left between at least a part of an outer wall of the embedded portion 322 and a channel wall of the channel 313, so as to form an air exhaust channel 50 that is in communication with the liquid storage cavity 13, so that air exhaust of the liquid storage cavity 13 can be realized during liquid injection.

In some embodiments, the liquid inlet tube 32 further includes a limiting portion 323, where the limiting portion 323 is disposed at one end of the sleeve portion 321 and is located between the sleeve portion 321 and the embedded portion 322.

In some embodiments, the limiting portion 323 is a hollow structure with two ends penetrating, and an annular blocking platform 325 is disposed on the inner side of the limiting portion 325, and the blocking platform 325 can be used to cooperate with the liquid injection device 2 for limiting.

In some embodiments, the liquid inlet structure 30 further includes an elastic member 33, the elastic member 33 is disposed in the liquid inlet tube 32, and in particular, in some embodiments, the elastic member 33 is disposed in the socket 321. The elastic member 33 can be sleeved on the upper base 212, and has one end abutting against the supporting surface 2122 and the other end abutting against the blocking wall 3212 of the sleeving part 321. The provision of the elastic member 33 facilitates the reciprocal movement of the liquid inlet tube 32 in the axial direction of the atomizing assembly 20 toward and away from the air outlet 14. That is, when the priming device 2 is assembled with the liquid inlet tube 32 and the priming device 2 applies pressure to the baffle 325 of the liquid inlet tube 32, the liquid inlet tube 32 can move away from the air outlet 14 along the axial direction of the atomizing assembly 20 under the action of the elastic member 33, so that the liquid inlet hole 3221 is at least partially carried out of the channel 313 or a communication channel is formed between the liquid inlet hole 3221 and the channel wall of the channel 313, thereby realizing the communication between the liquid inlet channel 40 and the liquid storage cavity 13; meanwhile, the sleeving part 321 can move to one side of the liquid supply hole 2111 far away from the air outlet 14, so that the whole liquid supply hole 2111 is completely shielded, and the atomization assembly 20 and the liquid storage cavity 13 are separated. After the priming device 2 withdraws from the liquid inlet tube 32, under the action of the elastic member 33, the liquid inlet tube 32 can move along the axial direction of the atomizing assembly 20 towards the direction close to the air outlet 14, so that the liquid inlet hole 3221 is completely brought into the channel 313 to realize the separation of the liquid inlet channel 40 and the liquid storage cavity 13, and meanwhile, the sleeving part 31 can move to one side of the liquid supply hole 2111 close to the air outlet 14, so that the liquid supply hole 2111 is communicated with the liquid storage cavity 13, and the liquid storage cavity 13 is communicated with the atomizing assembly 20. In some embodiments, the elastic member 33 includes, but is not limited to, a spring, an elastic silicone sleeve, a spring plate, and the like.

In some embodiments, the liquid inlet structure 30 further includes a first sealing member 34, where the first sealing member 34 is sleeved on the liquid inlet pipe 32, and is located on a side of the liquid inlet 3221 away from the air outlet 14. Specifically, in some embodiments, the first sealing member 34 may be sleeved at the limiting groove 324, and when the liquid inlet pipe 32 moves to the first position, the first sealing member may be brought out of the channel 313 along with the movement of the liquid inlet pipe 32, so that the liquid inlet hole 3221 is communicated with the liquid storage cavity 13. When the inlet pipe 32 is moved to the second position, the first sealing member 34 may be at least partially brought into the channel 313, sealing the gap between the inlet pipe 32 and the channel wall of the channel 313, thereby blocking the inlet opening 3221 from the liquid storage chamber 13 and preventing external air from entering the liquid storage chamber 13. In some embodiments, the first and second positions may be defined by the first seal 34, see fig. 2 and 5. In some embodiments, the first seal 34 may be a seal ring and may be removably assembled with the inlet tube 32.

In some embodiments, the atomizer 1 further comprises a liquid inlet channel 40, which liquid inlet channel 40 may be formed entirely in the liquid inlet aperture 3221, in other embodiments, the liquid inlet channel 40 may also be formed by the liquid inlet aperture 3221 and the gap communication between the insert portion 322 and the channel wall of the channel 313. When the liquid inlet channel 40 is communicated with the liquid storage cavity 13, the liquid matrix can be conveyed to the liquid storage cavity 13 through the liquid inlet channel 40, and the liquid inlet channel 40 can be isolated from the liquid storage cavity 13 through the first sealing member 34. In other embodiments, the separation of the liquid inlet channel 40 from the liquid storage cavity 13 can also be achieved by enlarging the size of the end of the embedded portion 322 away from the plug-in port 3223, so as to achieve interference fit with the channel wall of the channel 313.

In some embodiments, the atomizer 1 further includes an exhaust passage 50, where the exhaust passage 50 and the liquid inlet passage 40 may be separately disposed, and in particular, the exhaust passage 50 is formed on an outer wall of the liquid inlet tube 32, and the liquid inlet passage 40 may be disposed on a different side of the liquid inlet tube 32, so as to prevent the liquid matrix from being discharged from the exhaust passage 50 during liquid injection.
