Abstract: A filtration device that includes: a passage member defining a passage including an inlet and an outlet; and a filter disposed in the passage between the inlet and the outlet. The inlet has an inlet passage sectional area. The passage includes a first passage having a first passage sectional area that increases from the inlet toward the filter on an upstream side of the filter, and a second passage having a second passage sectional area that is uniform from the first passage toward the filter. The second passage sectional area is greater than the first passage sectional area, and a second passage length of the second passage is greater than a first passage length of the first passage.

Abstract: A nebulizer includes a case and a nozzle. The case has an inner wall which defines an internal space. The nozzle atomizes a liquid stored in the internal space. The case includes a discharge outlet for guiding the atomized liquid to the outside of the case. The nozzle has a gas hole and a liquid hole. The gas hole ejects a gas. The liquid hole is located adjacent to the gas hole and ejects the liquid. In the internal space, the case does not have any path formed of a straight line which extends from the gas hole to the discharge outlet by passing only through the internal space.

Abstract: An atomizing apparatus having a top surface and a bottom surface includes a first tubular body, a second tubular body, pumps, and an atomizing portion. The pumps are disposed in the first tubular body and have an intake hole and a discharge hole. The atomizing portion is configured to atomize a liquid supplied to the housing by a gas discharged through the discharge hole of one of the pumps. The first tubular body has a first cavity and a first communication hole that is in communication with the second tubular body. The second tubular body has a second cavity and a through-hole. The through-hole is in communication with the first communication hole. The atomizing portion is disposed at the through-hole. The first cavity is disposed at a position closer than the through-hole to the top surface.
