• an nebulization module, installed at the opening and interconnected to the liquid storage space;
• a power supply, electrically coupled to the nebulization module, for supplying electric power to drive the nebulization module to operate;
• and
• a power extraction module, installed in the casing and penetrated through the cap, and an end of the power extraction module extending to the bottom inside the container;
• when use, the power extraction module sucks the liquid to be nebulized inside the container into the liquid storage space, and then operates the nebulization module to release, nebulize and spray the liquid to be nebulized in the liquid storage space.
