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: A case of a nebulizer includes a discharge outlet that communicates with the outside of the nebulizer. A nozzle has a gas hole and a liquid supply path. The gas hole can supply an output gas. The liquid supply path uses a liquid hole as an opening at one end and a suction inlet as an opening at the other end. The liquid hole is located adjacent to the gas hole and can supply a liquid to an internal space. The suction inlet sucks a liquid to be supplied to the liquid hole. An opening center, which is the centroid of the discharge outlet when an opening surface of the discharge outlet is seen in a plan view, is displaced from a virtual first reference axis. The first reference axis is parallel with the pointing direction of the gas hole and passes through the gas hole.

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.

Abstract: A CPAP machine includes a housing, an air pipe, a blower, and a sensor S. The housing includes a first opening and a second opening. The air pipe is disposed in the housing, and has an inlet port continuous with the first opening, and an outlet port. The sensor S measures a temperature or a humidity of a gas that flows through an internal space of the air pipe. The air pipe includes a box that protrudes outward from a wall of the air pipe and a wall disposed in the box. The wall is disposed in the box to define a space continuous with the internal space of the air pipe, a space, and a space that connects the space and the space to each other. The sensor S is disposed at a wall of the box.

Abstract: An atomizer includes a gas supply member provided with a gas supply port configured to supply a gas and a liquid supply member provided with a liquid supply port configured to supply a liquid. The gas supply member has a gas supply surface as a surface to form the gas supply port, the liquid supply port is opened toward an axis orthogonal to the gas supply surface at the gas supply port, and the liquid supply member has a first inclined surface between the liquid supply port and the gas supply port. The first inclined surface is inclined to leave from an axis orthogonal to the gas supply port as the first inclined surface extends away from the gas supply surface in a first section including a gas flow path and a liquid flow path.
