The manner of pressing the operation end 2212 includes, but is not limited to, directly pressing by hand or pressing by a liquid injection tool, as long as the walls of the communication groove 2213 and the cavity of the cavity 223 are elastically deformed inward. Wherein, the liquid injection tool includes but is not limited to tweezers and the like.

Wherein, the quantity that sets up of shutoff piece 22 is two, and two shutoff pieces 22 intervals set up on base main part 21, if any one of them shutoff piece 22 damages, lead to this shutoff piece 22 can't be taken out, and another shutoff piece 22 has played reserve purpose, guarantees that atomizer 100 still can normally annotate the liquid, has improved atomizer 100's life.

To sum up, in the atomizer 100 according to the second embodiment of the present invention, the communication groove 2213 is formed on the operation end 2212 and communicates with the cavity 223, the communication groove 2213 extends the elastically deformed space to the operation end 2212, when the operation end 2212 is pressed and the walls of the communication groove 2213 and the cavity of the cavity 223 are elastically deformed inward, the interference fit between the outer surface of the blocking member 22 and the wall of the through hole 211 disappears, the locking protrusion 2211 is elastically deformed by the pressing of the second protrusion 2132, the locking between the locking protrusion 2211 and the wall of the through hole 211 is released, the blocking member 22 is moved away from the liquid storage cavity 11, so that the blocking member 22 can be taken out, the atomizer 100 according to the second embodiment of the present invention has the advantage that the blocking member 22 can be conveniently detached and the aerosol can be repeatedly filled into the liquid storage cavity 11 to form the matrix, or the user can replace the damaged blocking member 22, ensuring proper use of the atomizer 100.

The above embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
