DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
THIS INVENTION relates to improvements in or in relation to negative air ion generators for production of small biologically active (ingestible) ions.
BACKGROUND ART
The thrust of experimental data to date shows that small negatively charged air ions are biologically active providing improved health through ingestion of negative air ions over time.
Ion depletion in modern urban life by air borne pollutants has been documented as producing adverse effects on body serotonin levels and production of higher than normal histamine levels in some people producing adverse physiological and psychological effects.
The presence of negative air ions capable of being inhaled and ingested has been shown to assist the body to return to its own natural balance producing positive effects on health.
At present, negative ion generators suffer from a number of disadvantages.
At present, negative air ion generators are not capable of producing small highly mobile biologically active negative ions consistently over an extended time period and the lack flexibility in terms of the variability of production rate and quantities of ions produced.
In addition, due to the high voltages employed to produce ions, ion generators are prone to corrosion and wear so that ion generation can cease without a user being aware.
OUTLINE OF THE INVENTION
It is an object of the present invention to alleviate at least to some degree the above-mentioned deficiencies of the prior art.
In devising the present improvements to negative ion generators, the applicant has produced a number of independent inventions which can be used separately but have synergism and are more preferably used together in combination.
Nevertheless, the applicant recognizes the possibility that inferior products may be made utilizing one or more of the applicant's inventions.
The applicant has therefore set out in this present specification, each invention in independent form and also in combination and reserves the applicant's rights to divide each invention or to claim the inventions in novel combination.
In the present invention, there is provided a negative air ion generator comprising an emitter, typically a needle point, a driver circuit for generating ions at the emitter, the drive circuit producing an ion generation signal, the ion generation signal comprising a carrier wave which is frequency modulated at a selected one of a number of selectable frequencies. The selectable modulation frequencies are typically about 40 Hz, about 25 Hz, about 10 Hz or about 7.83 Hz. The carrier frequency is from 15 kHz to 20 kHz with about 17.25 kHz being typical.
In one form, there is provided a negative air ion generator having at least one needle assembly having a needle point and a driver circuit providing voltage to the needle point to produce air ions, the needle assembly having a socket surrounded by a socket housing carrying a terminal extending from the housing terminal being soldered in the driver circuit, the needle point being removably held in the socket, the socket, socket housing and terminal being plated over its entire surface with a corrosion resistant metal such as gold or its functional equivalent.
The needle point is preferably made from a corrosion resistant alloy. Typically, a ruthenium alloy is employed.
In a second form, there is provided a negative air ion generator having at least one needle assembly including a replaceable needle point and a driver circuit 28, 28' providing voltage to the needle assembly to generate ions at the needle point, a time circuit 172 and a needle replacement indicator, 170 the time circuit being operable to actuate the needle replacement indicator after a predetermined period of time indicative of expiration of needle life. Typically, expiration of needle life is not usually complete cessation of ion production but is an average time period beyond which ion production slows and is a recommended time for replacement.
The timing circuit 172 preferably includes a solid state memory device periodic
