Further, referring primarily to fig. 6 and secondarily to fig. 3, the first sealing member 500 includes a first base portion 510 and a first annular protrusion 520. The first base 510 is substantially disc-shaped and has a first through hole 511. The first base 510 is embedded in the first circular groove 103 of the base 100.

The first inner groove 512 is annular and is disposed opposite to the first annular protrusion 520. The strength of the first base 510 at the first inner groove 512 is lower, and thus the first sealing element 500 is more easily deformed after the first annular protrusion 520 is subjected to external pressure. Good deformation means that slight contact also produces a good sealing effect. Similarly, the second base part is provided with a second inner groove at the side facing away from the second annular protrusion. The second inner groove is annular and is opposite to the second annular bulge.

Referring to fig. 7, the atomizing plate 300 includes a piezoelectric ceramic plate 310 and a metal plate 320, and the piezoelectric ceramic plate 310 and the metal plate 320 may be bonded or the metal plate 320 may be baked to connect with the piezoelectric ceramic plate 310, which is not limited herein. The piezoelectric ceramic plate 310 has a positive terminal 311 on a side away from the metal plate 320, and the metal plate 320 has a negative terminal 321.
