Wherein the end of the fixed outer ring 61 is disposed at the bottom outside of the water tank 1 and the groove bottom of the first seal groove 7 is disposed at the upper end of the atomizing cover 2, or the end of the fixed outer ring 61 is disposed at the upper end of the atomizing cover 2 and the groove bottom of the first seal groove 7 is disposed at the bottom outside of the water tank 1.

Taking the retainer ring 61 as an example. The end of the fixed outer ring 61 is provided at the upper end of the atomizing cover 2 means that: one end of the fixed outer ring 61 can be connected with the upper end of the atomizing cover 2 in a sealing way by any existing technical means, so that the fixed outer ring 61 and the atomizing cover 2 are integrated, for example, the fixed outer ring 61 and the atomizing cover 2 are integrated into a whole, and the fixed outer ring 61 extends upwards from the upper end of the atomizing cover 2; the end of the fixing collar 61 is disposed outside the bottom of the water tank 1 means: one end of the fixing collar 61 may be fixedly connected to the bottom outside of the water tank 1 by any conventional means, for example, one end of the fixing collar 61 is welded to the bottom outside of the water tank 1 by hot melt welding, or the fixing collar 61 and the water tank 1 are integrally formed, and the fixing collar 61 is formed by extending the bottom of the water tank 1 downward. Similarly, the arrangement of the bottom of the first sealing groove 7 at the bottom outer side of the water tank 1 or the upper end of the atomizing cover 2 means that the bottom of the first sealing groove 7 is fixedly connected with the bottom outer side of the water tank 1 or the upper end of the atomizing cover 2 by any prior art means, and the first sealing groove 7 and the water tank 1 form a whole (at this time, the notch of the first sealing groove 7 faces downwards) or the first sealing groove 7 is located at the upper end of the atomizing cover 2 and forms a whole at the atomizing cover 2 (at this time, the notch of the first sealing groove 7 faces upwards).

As shown in fig. 6, the upper end surface of the body of the sealing ring 5 is provided with a stress surface 51, a deformation groove 52 for providing elastic deformation of the sealing ring 5 is arranged on the body below the stress surface 51, and the inner side surface and the outer side surface of the body of the sealing ring 5 are respectively provided with a first sealing side lug 53 protruding outwards.
