Abstract: A nebulizer with a negative pressure structure includes a nebulization body, a carrying cavity, a nebulizing element and a negative pressure generating element. The carrying cavity is provided for carrying a nebulized liquid and has a through hole. The nebulizing element is installed at the through hole and includes a piezoelectric driving unit and a nebulizing plate disposed on a side of the piezoelectric driving unit. The negative pressure generating element is formed on the carrying cavity and provided for changing the volume of the carrying cavity or removing air from the carrying cavity to reduce the air pressure in the carrying cavity, so as to nebulize a liquid of low surface tension or high viscosity effectively.

Abstract: In an atomizer with a liquid supplement container, the atomizer includes a casing and an atomization device covered by the casing, and the container is filled with a supplementary liquid and has a seal disposed at an opening of the container for easy storage and carry. The casing further includes at least one installing slot, and a seal destruction structure installed in the installing slot, and the installing slot is coupled with the atomization device. When the container is installed in the installing slot, the seal destruction structure destruct the seal to allow the supplementary liquid to flow into the installing slot for the atomization by the atomization device, so as to improve the convenience of use, prevent the supplementary liquid from contaminating the casing or causing failure of the atomization device.

Abstract: A nebulization structure includes a driving element, a structure plate and a nebulization plate. The structure plate is installed on a side of the driving element, and the structure plate is substantially in a circular disc shape and has a plurality of through holes, and at least one rib is formed between adjacent through holes to define a water guide passage. The nebulization plate is clamped between the driving element and the structure plate and made of a polymer material to overcome the problems of having easy metal fatigue and embrittlement of the nebulization plate made of metal, and being corroded by corrosive liquids.
