The air intake port 321 is further configured to route incoming air to the inner wall of the tank cover 32 and the inner wall of the tank body 31 to induce compactness, improving the ascent. diffused fog consisting of droplets of aromatic fluid. Referring again to FIGS. 1 and 3, the ramp-shaped flat weir 75, the connection hole 72 and the connecting tube 322 are disposed in communication with each other, the diffused mist consisting of fluid droplets The aromatic can be expelled from the tank body 31 of the fluid reservoir 30 through the flow of pressurized incoming air into the outside free air via the ramp-shaped flat weir 75, creating a visual effect. Referring again to FIG. 2, the rotating connection structure between the lower support shell 10 and the cover shell 70 facilitates general maintenance and cleaning activities. This rotating connection structure comprises a plurality of fixed stops 16 protruding from an inner side of the upper flange 101 of the lower support shell 10, a lower connecting flange 18 extending downward from the lower side. the cover shell 70 aligned with its inner wall, and a plurality of L-shaped retention grooves 771 located on the lower connecting flange 77.

The operation of the rotating connection structure between the lower support shell 10 and the cover shell 70 is explained hereinafter. As illustrated in Figures 6-1, 6-2 and 6-3, to attach the cover shell 70 to the lower support shell 10, direct the short sides 7710 of the L 771 on the respective fixed abutments 16, 15 and then inserting the lower connecting flange 77 of the cover shell 70 into the upper flange of the lower support shell 10, and then rotating the cover shell 70 with respect to the lower support shell 10 in a clockwise direction to urge the respective L-shaped holding grooves 771 to engage with the respective fixed stops 16. The cover shell 70 is then locked with the lower support shell 10 and can not be separated from the lower support shell 10 vertically. As illustrated in FIGS. 6-4, to separate the lower support shell 10 and the cover shell 70, rotate the lower support shell 10 with respect to the cover shell 70 in an anti-clockwise direction at maximum to separate the connection, thereby directly separating the cover shell 70 from the lower support shell 10. In conclusion, the nebulizing aromatic diffuser of the present invention is characterized in that the arrangement of the side block at the periphery the fluid reservoir and the formation of the pressurized space between the cover shell and the fluid reservoir improve the fog diffusion effects and optimize the storage capacity of the fluid; the design of the ramp-shaped flat weir of the cover shell enhances the decorative and visual effects of aroma diffusion; the rotating connection structure between the lower support shell and the cover shell facilitates general maintenance and cleaning activities.
