Abstract:
1. An inhaler comprising an apparatus body and a compressor for sending compressed air and for generating aerosol inside said apparatus body and supplying the aerosol to outside of said apparatus body to allow a user to inhale the aerosol, said apparatus body including an aerosol generation portion including a reservoir portion storing liquid and an atomization portion atomizing liquid stored in said reservoir portion into spray particles and applying the atomized spray particles to outside air introduced into said apparatus body, and an aerosol lead-out portion; wherein said aerosol lead-out portion comprises: a lower tubular portion connected to said aerosol generation portion, extending in a first direction and defining a first flow passage portion; an upper tubular portion with an aerosol lead-out opening leading aerosol generated in said aerosol generation portion to outside and extending in a second direction different from said first direction and defining a second flow passage portion; and a corner flow passage portion, located between the lower tubular portion and the upper tubular portion, said lower tubular portion, said upper tubular portion and said corner flow passage portion together forming a lead-out flow passage consisting of said first flow passage portion, said second flow passage portion and said corner flow passage portion for leading aerosol generated in said aerosol generation portion to outside through said aerosol lead-out opening without passing through any valve; a pair of exhalation discharge openings having no valves in side walls of said upper tubular portion proximal to said corner flow passage portion and mutually facing and unblocked from each other, and first and second narrowing walls that reduce the cross section of the second flow passage portion, each of the first and second narrowing walls extending obliquely from opposing inner side surfaces of the upper tubular portion proximate the exhalation discharge openings, wherein the first and second walls each have a first end positioned on opposite ones of the opposing inner side surfaces and a second free end, wherein the second free ends of the first and second walls mutually face and are spaced from each other to form an aerosol outflow opening in the second flow passage of reduced cross section than the second flow passage portion, wherein the first and second walls are shaped to direct exhaled air to the exhalation discharge openings.
