A DC-AC frequency converter type nose cleaner includes an electromagnetic pump, a container storing a cleaning solution, a nose-washing tool and a frequency converter circuit driving the electromagnetic pump. The frequency converter circuit at least includes an oscillator circuit, a bistable circuit and a push-pull circuit. The swing speed, the swing frequency and the swing amplitude of the swing arms vary with the change of the oscillation frequency of the oscillator circuit. The DC-AC frequency converter type nose cleaner can change the pressure and the flow generated by the electromagnetic pump so as to satisfy the requirement of the discharge pressure and flow of the nose cleaner so as to overcome the defect of the discharge pressure of the conventional nose cleaner that is too big to hurt the user.
