Referring to FIGs. 3 and 4, the upper cover 21 includes an outer casing 212 and an inner casing 211 received in the outer casing 212. The space between the outer wall of the inner casing 211 and the inner wall of the outer casing 212 forms a receiving groove 214. The outer wall of the inner casing 211 is protrudingly formed with a limiting block 2111 along the radial direction of the inner casing 211. The bottom wall of the inner casing 211 is recessed upward to form an annular groove 2112.

The abutting ring 242 has a diameter smaller than the movable member main body 241. Three recesses 2421 are provided on the outer peripheral surface of the abutting ring 242. The width dimension of the recess 2421 is greater than or equal to the diameter dimension of the locking member 22, so that the locking member 22 can be at least partially received in the recess 2421. The recess 2421 is smoothly transitionally connected with the outer peripheral wall of the retaining ring 242. The inner wall of the abutting ring 242 is recessed inwardly along the radial direction of the abutting ring 242 to form an arc-shaped limiting groove 2422. The limiting groove 2422 passes through the lower end surface of the abutting ring 242. The lower end surface of the movable member main body 241 is protrudingly provided with a limiting ring 244, and the limiting ring 244 abuts against the abutting surface 2123, thereby restricting the locking member 22 from moving in the axial direction of the upper cover 21.

The cooperation of the abutting block 2124 and the clamping groove 514 prevents the upper cover 21 from rotating with the movable member 24.
By rotating the movable member 24, the movable member 24 drives the latching member 23 to rotate relative to the upper cover 21 and the battery sleeve 51, the limiting block 2111 slides in the limiting groove 2422; when the limiting block 2111 abuts against one end of the limiting groove 2422, the recess 2421 of the abutting ring 242 is misaligned with the containing groove 2121 (or the locking member 22), the outer peripheral wall of the abutting ring 242 abuts against the locking member 22, so that one end of the locking member 22 away from the abutting ring 242 is protruded from the upper cover assembly 20 through the through hole 2122 and then is locked in the locking groove 512. Since the locking member 22 is locked in the locking groove 512, the upper cover assembly 20 and the battery assembly 50 are tightly connected, thereby preventing children from easily opening the upper cover assembly 20 to contact the e-liquid.
When the remaining amount of the e-liquid in the liquid storage chamber 161 is insufficient requiring for liquid injection, the movable member 24 is rotated in a reverse direction until the limiting block 2111 resists the other end of the limiting groove 2422, the movable member 24 stops to be rotated, the recess 2421 is aligned with the locking member 22, so that the locking member 22 is partially received in the recess 2421 and is separated from the locking groove 512, so that the locking relationship between the locking member 22 and the locking groove 512 is released. At this time, by pulling the upper cover assembly 20 away from the battery assembly 50, the upper cover assembly 20 is separated from the liquid storage assembly 10, and then the liquid sealing member 15 is pulled out or the liquid sealing member 15 is pierced through using a liquid injection needle to inject liquid into the liquid storage chamber 16. At this time, the liquid storage assembly 10 can be poured out from the open end 511 separately; alternatively, the atomizing assembly 40 and the liquid storage assembly 10 can be poured out from the open end 511.
It is understood that, the atomizing assembly 40 and the battery assembly 50 are in contact by abutting against each other. Or, the liquid storage assembly 10 and the atomizing assembly 40 are in contact by abutting against each other.
The electronic cigarette further includes a fixing member, the fixing member is sleeved at the outside of the upper cover 21, the locking groove 512 is formed by recessing from the inner wall of the fixing member, the clamping groove 514 is provided on the fixing member, the upper cover assembly 20 is rotatably arranged on the fixing member by the locking member 22 being locked in the locking groove 512 of the fixing member. In this embodiment, the fixing member is the battery sleeve 51. It is understood that, in other embodiments not shown, the fixing member may also be the liquid storage tube 11, the liquid storage tube 11 extends upward to form a connecting pipe, the connecting pipe is sleeved at the outside of the upper cover 21, and the locking groove 512 is provided in the inner wall of the connecting pipe. A tight connection between the upper cover assembly 20 and the liquid storage assembly 10 is realized by the locking member 22 being locked in the locking groove 512 of the connecting pipe, thereby preventing children from easily opening the upper cover assembly 20 to contact the e-liquid.
In some embodiments, the atomizer 100 provided by the present application has a locking member 22 movably provided in the upper cover 21, the movable member 24 is provided with a recess 2421 corresponding to the locking member 22. When rotating the movable member 24 relative to the upper cover 21, the movable member 24 can abut against the locking member 22, so that the locking member 22 protrudes out from the upper cover assembly 20 and is locked in the locking groove 512, thereby preventing children from easily opening the atomizer 100 to contact the e-liquid and improving the safety of the atomizer 100. The structure is simple and the operation is convenient. Or, the movable member 24 is rotated relative to the upper cover 21, so that the locking member 22 is received in the recess 2421, the locking relationship between the locking member 22 and the locking groove 512 is released, and the upper cover assembly 20 is opened for liquid injection operation.
