Document Type and Number:
WIPO Patent Application WO/2023/145779
Kind Code:
A1
Abstract:
A case (30) of this nebulizer (10) has a discharge port (71) which is in communication with the outside. A nozzle (80) comprises: a gas hole (GH) through which a pressure-fed gas can be supplied; and a liquid supply path (RL) in which an opening at one end is a liquid hole (LH) which is located in proximity to the gas hole (GH) and through which liquid can be supplied to an interior space (S), and an opening at the other end is an intake hole (IH) through which the liquid to be supplied to the liquid hole (LH) is sucked in. An opening center (CP), which is the geometric center of the opening plane of the discharge port (71) as seen in a plan view, is out of alignment with respect to a virtual first reference axis (AX1) that is parallel to the direction in which the gas hole (GH) is oriented and that passes through the gas hole (GH). When the direction from the gas hole (GH) toward the opening center (CP) as seen in the direction along the first reference axis (AX1) is defined as a specified direction, the entire range of the intake hole (IH) is situated on the specified direction side with respect to the gas hole (GH).
