When atomization assembly 12 is not installed, opening 1151 and discharge port 1113 are offset to enclose discharge port 1113, and when atomization assembly 12 is installed, opening 1151 and discharge port 1113 are aligned to communicate reservoir chamber a with atomization assembly 12. In other embodiments, the blocking plate 115 may also be an arc-shaped curved plate-like structure that is rotatably disposed, and blocks or unblocks the liquid outlet 1113 when rotating.

In this embodiment, the blocking plate 115 is provided with a thread for screwing the atomizing assembly 12, and the atomizing assembly 12 is screwed with the blocking plate 115.

As shown in fig. 4 and 5, the stopper 115 includes a sleeve 1152 fitted to the inner wall surface of the inner tube 111, and a collar-shaped stopper 1153 provided at the lower end of the sleeve 1152, and an opening 1151 corresponding to the liquid outlet 1113 is provided in the sleeve 1152. The stopping portion 1153 is coaxial with the sleeve 1152, the outer diameter of the stopping portion is larger than that of the sleeve 1152, and the upper end of the stopping portion 1153 abuts against the bending portion 1111 to axially position the baffle 115.

A flange 1162 which abuts against the lower end of the stopping portion 1153 is formed on the inner ring of the third sleeve 1161, the third sleeve 1161 is usually riveted with the sleeve portion 1112, it is ensured that the installation position is fixed, and the flange 1162 can abut against the lower end of the blocking piece 115, so that the blocking piece 115 is prevented from moving axially or falling out.

Preferably, the stopper 1153 has an inner wall surface formed with a screw thread for mounting the atomizing assembly 12. In other embodiments, the threads on the baffle 115 for mounting the atomizing assembly 12 may also be formed on the inner wall surface of the socket 1152. The flange 1162 abuts against the outer edge of the end face corresponding to the stopper 1153, and the edge of the end face corresponding to the stopper 1153 and the flange 1162 is provided with an inclined surface 1154 which is guided to the inner wall surface of the stopper 1153.

In some embodiments, angled surface 1154 is provided with knurling or circumferentially spaced grooves that increase friction with blade 115 after atomization assembly 12 is tightened against blade 115.

A first friction force is provided between the blocking piece 115 and the inner tube 111 of the liquid storage assembly 11, so that when the atomization assembly 12 is installed, the atomization assembly is screwed and fixed with the blocking piece 115, and then the blocking piece 115 is driven to rotate together to open the liquid outlet 1113 by overcoming the first friction force.

When the atomizing assembly 12 is screwed onto the baffle 115, the sealing ring 122 is in close contact with the inclined surface 1154, and the friction between the sealing ring 122 and the inclined surface 1154 is significantly increased when the sealing ring is engaged with the groove. By adjusting the friction between the blocking piece 115 and other components at the installation position, when the atomization assembly 12 is installed, the blocking piece 115 is driven to rotate after the screw-threaded portion 1211 is matched with the screw thread on the blocking piece 115 in place, so as to open the liquid outlet 1113; when the atomizing assembly 12 is removed, the blocking plate 115 is driven to rotate to close the liquid outlet 1113 by the friction force between the sealing ring 122 and the groove on the blocking plate 115, and then the atomizing base 121 is rotated relative to the blocking plate 115 to separate the threads, so that the atomizing assembly 12 is axially removed. In other embodiments, the blocking piece 115 can also be engaged with the atomizing base 121.

As shown in fig. 5, in order to limit the liquid outlet 1113 to be opened or closed just before or after the rotation of the blocking plate 115, and prevent the liquid outlet 1113 from being opened or closed again due to an excessively large or excessively small rotation angle, the atomizing device 10 is provided with a limiting mechanism for limiting the rotation interval of the blocking plate 115.

Preferably, the stop mechanism includes an arcuate slot 1114 disposed on the inner tube 111 and a boss 1155 disposed on the flap 115 that snaps into the arcuate slot 1114.

At this time, after the baffle 115 rotates by 45 degrees, the opening 1151 and the liquid outlet 1113 can just open the liquid outlet 1113 relatively, and after the baffle 115 rotates by 45 degrees reversely, the opening 1151 and the liquid outlet 1113 can just close the liquid outlet 1113 by dislocation. In other embodiments, when four liquid outlets 1113 and four openings 1151 are circumferentially arranged, the rotation angle of the boss 1155 in the arc-shaped groove 1114 may be smaller than 45 degrees, and the circumferential radian of the liquid outlets 1113 and the openings 1151 may be correspondingly adjusted. Or when the liquid outlets 1113 and the openings 1151 are arranged in other numbers and manners along the circumferential direction, the rotation angle of the boss 1155 in the arc-shaped groove 1114 is correspondingly adjusted.
