The bottom end of the cover 220 is provided with at least one notch 222 for guiding the liquid 2 to the annular gap 221. More specifically, the contact surface of the bottom of the conventional cover with the liquid is a smooth linear shape. When the liquid gradually decreases, the smooth linear shape is not conducive to attracting the remaining liquid, and the remaining liquid cannot be transferred to the annular gap. Causes the problem of capillary failure. However, when the bottom end of the cover 220 is provided with the notch 222, the originally smooth linear contact surface will be broken, and the liquid will easily gather at the notch due to the adhesion force, and then the liquid cohesion will generate Agglomeration, thereby solving the problem that the residual liquid is not easy to be transferred.

The liquid outlet 224 is located at the center of the circle, but the invention is not limited to this. The extending direction of the liquid outlet 224 and the extending direction of the jet hole 212 are perpendicular to each other. More specifically, when the liquid 2 flows from the liquid outlet 224 When it overflows, it will be hit by the high-pressure gas jetted vertically upward from the jet hole 212 below, so that the liquid 2 will be hit by the high-pressure gas to form atomized particles.

The liquid 2 is impacted by high-pressure gas, which will affect the size of the atomized particles and reduce the atomization rate. Therefore, preferably, the top of the protrusion 2204 has a rib 2205 extending from the top of the protrusion 2204 to The top of the cover 220 is used to guide and remove the water remaining on the top of the protrusion 2204. When the accumulated water accumulates on the top of the protrusion 2204, it can slide down to the top of the cover 220 along the rib 2205, so as to eliminate the water accumulation on the top of the protrusion 2204 and reduce the probability of the water supply balance being damaged. In another embodiment, the top of the protrusion 2204 has a groove 2206 that extends from the top of the protrusion 2204 to the top of the cover 220 for guiding and removing the accumulated water remaining on the top of the protrusion 2204.
