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.

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: A nebulizer includes a housing and a mouthpiece. The housing surrounds a pump for spraying a liquid reagent out of the nebulizer. An opening is formed in the housing. The inside and the outside of the housing communicate with each other through the opening. Arrow indicates an air flow from the opening to an inlet of the pump. The air flow indicated by arrow passes by the outer surface of the pump

Abstract: An atomizer includes a first piezoelectric pump, a first flow path, a reservoir part, and a second flow path. The first piezoelectric pump ejects gas through an outlet. The first flow path has a first end and a second end. The first end of the first flow path is connected to the outlet of the first piezoelectric pump. A connection point is provided between the first and second ends of the first flow path. Liquid is to be stored in the reservoir part. The second flow path has a first end and a second end. The first end of the second flow path is connected to the liquid reservoir part. The second end of the second flow path is connected to the connection point.
