Abstract:
1. A DC-AC frequency converter-type nose cleaner, comprising: a container storing a cleaning solution; an electromagnetic pump which comprises an electromagnetic device, a pump housing, two stretchable and elastic bladders provided at outer surfaces of said pump housing respectively, two swing arms, and two magnetic members, wherein said electromagnetic device has two side magnetic poles and a middle magnetic pole, wherein first ends of said swing arms are disposed on two outer sides of said pump housing respectively, wherein said magnetic members are provided at second ends of said swing arms with a distance from said electromagnetic device, wherein said pump housing is divided into a first chamber and a second chamber, wherein said first chamber has an inlet connector communicated with said container through a negative pressure channel, wherein said second chamber has an outlet connector, wherein said swing arms swing reciprocatingly for drawing said cleaning solution into said first and second chambers from said inlet connecter and discharging said cleaning solution from said outlet connecter; a nose-washing tool having a fluid inlet end communicated with said outlet connector through a positive pressure channel, and a fluid outlet end, wherein said nose-washing tool comprises a spray nozzle provided at said fluid outlet end, wherein when said electromagnetic pump is activated, said negative pressure channel draws said cleaning solution in said container and supplies said cleaning solution to said nose-washing tool for discharging said cleaning solution from said spray nozzle; a frequency converter circuit which comprises an oscillator circuit for transforming DC into a single-phase oscillating signal, a bistable circuit and a push-pull circuit, wherein said bistable circuit splits said single-phase oscillating signal into a N-phase stimulus signal and a S-phase stimulus signal, wherein both said N-phase stimulus signal and said S-phase stimulus signal respectively activate magnetism of said two side magnetic poles of said electromagnetic device and magnetism of middle magnetic pole of said electromagnetic device to alternatively switch between a N-phase and a S-phase, wherein said two side magnetic poles and said middle magnetic pole are selectively attracted or repulsed by said two magnetic members respectively to force said swing arms to swing reciprocatingly, wherein said push-pull circuit amplifies and transports said N-phase stimulus signal and said S-phase stimulus signal to said electromagnetic pump to force said swing arms of said electromagnetic pump to swing effectively, wherein said frequency converter circuit is arranged for using said DC to activate said swing arms of said electromagnetic pump to swing reciprocatingly, wherein oscillating frequency of said oscillator circuit is adjusted to change a swing speed, a swing frequency and a swing amplitude of said swing arms of said electromagnetic pump, so as to further change a discharge pressure and a discharge flow of said electromagnetic pump for said nose cleaner.
