Abstract: The present application provides an atomizer structure and an atomizer having the same. The atomizer structure includes: a spray assembly including a first cavity; a bottle body configured for containing liquid and configured to be connectable to the spray assembly, the bottle body comprises a second cavity; a first connecting member communicating the first cavity and the second cavity and configured for guiding the liquid contained in the second cavity to enter the first cavity, when an air pressure in the first cavity is less than an air pressure in the second cavity; and a second connecting member selectively communicating the first cavity and the second cavity such that a quantity of remaining liquid in the first cavity can enter the second cavity, and configured for preventing liquid in the second cavity from flowing into the first cavity when the atomizer structure is tilted or inverted.

Abstract: A fluid diffuser for atomization of essential oils can have a flexible seal used to reduce internal pressure of an air chamber adjacent to the atomizer. It can also use a cover and a sensor to control the operation of the atomizer based on the position of the cover. An atomizer housing portion of the diffuser can be removable and replaceable relative to a lower portion of the housing.
