Title: Nano bubble generating nozzle and oral cleaning device including the same

Abstract: Disclosed is a nano bubble generating nozzle including: a passage passing through an interior thereof to provide a flow path through which liquid flows; a nano bubble generating part corresponding to a part of the passage, and formed such that a cross-section of the nano bubble generating part becomes small and then large again along a flow path of liquid so that the nano bubble generating part has a pressure lower than an external pressure of the nozzle body; and a gas inlet formed in the nozzle body, and connected to the nano bubble generating part so that gas is introduced into the nano bubble generating part due to a difference between an external pressure of the nozzle body and a pressure in the nano bubble generating part.
