Detailed Description of the Invention:
One embodiment (200) of the anion generator of the present invention is illustrated in the
accompanying drawings # 1 # 2 and # 3. It generates a high static voltage by means of a single electrical circuit to convert air molecules into anions and pushes them out into surrounding air.
The anion generator (200) is housed in a ABS-plastic housing of 2 mm wall thickness for indoor use only. It is comprised of a housing, horizontally split into an upper housing (10) and a lower housing (30). Cross section of the housings is square.
The upper housing (10) houses the electrode (20), which is constructed of a cluster of 14 titanium metal wires (25), as illustrated in the accompanying drawing # 5.
The inventive feature of the present invention resides in employing fourteen strands (25) of pure titanium metal, each of which has an uniform cross section of 36 SWG, assembling them at one ends (21) into a cluster and dispersing the other ends (22) of the wires (25) into a horizontal plane such that the fourteen wires uniformly cover the circular perimeter across 360 degrees.
The second inventive feature of the present invention hereafter resides in the marginal curving of the fourteen titanium metal wires (25) into anti-clockwise direction for the cluster (20) to resemble in shape a flattened umbrella.
The electrode (20) is firmly soldered to a printed circuit board (24), which is held in vertical position on its one longitudinal side, as illustrated in the accompanying drawing # 5. The fourteen wires of the electrode (20) must clear the longitudinal side of the printed
circuit board (24).
The lower housing (30) is hollow and trapezium-shaped. It is covered at top end with a horizontal plastic plate (34) that holds at its centre point (31-A) twin, U-shaped holders (32, 32-A). The printed circuit board (24) firmly is seated in the twin, U-shaped holders (32, 32-A), as illustrated in the accompanying drawings # 2 and # 5. The upper housing (10) is contiguous with the hollow, lower housing (30). The gradient of the four sides of the housings (10, 30) is 2 degrees.
The upper housing (10) functions to riot only shield the electrode (20) from accidental physical contact by user but also to house air vents (15), that cover the maximum available surface area of the upper housing (10), as illustrated in the accompanying drawing # 4.
The third inventive feature of the present invention resides in the upper housing (10) in terms of the provision of plurality of elongated, ribbed air vents (15), covering the maximum available surface area of the upper housing (10), for intake of fresh air through the horizontal top plate (11) and for discharge of anions generated through the four sides of the upper housing (10).
The ribbed upper housing (10), encasing the electrode (20), induces mini-cyclonic conditions that push out the anions - as soon as they are generated by the electrode (20) - through the four ribbed sides (12,12-A, 13, 13-A). The ribbed construction ensures highest strength to the upper housing (10), which is constructed of ABS plastic.
Width of the air vent (15) in the upper housing (10) is set to exceed thickness of the intervening rib in ratio of 4:1 and the radii of curvature of the four corners (11 -A, 11 -B, 11-C, 11-D) of the top plate (11) with a view to minimize resistance to air flow and the anions generated.
The lower housing (30) has a stepped perimeter (33) that firmly holds and seats the upper housing (10) in assembled position with the lower housing (30), as illustrated in the accompanying drawings # 1 and # 3. The lower housing (30) is taller than the upper housing (10) by a ratio of more than 2:1 and interiorly houses a square-shaped casing (40), which stores the electrical circuit, as illustrated in the accompanying drawing # 7.
The square-shaped casing (40), resting on side wings (40-A, 40-B), is fitted in a vertical position within the hollow, lower housing (30), with its one square-shaped vertical side (43) being parallel to the vertical plane of one side (31-A) of the horizontal top plate (34) of the lower housing (30). High voltage cable terminals (41, 41-A), leaving from top edge (42) of the vertical side (43) are led through two holes (35, 36), provided in the proximity of the twin U-shaped holders (32, 32-A) and are soldered to the printed circuit board (31).
The sole electrical circuit sealed in the casing (40) for generating high, static voltage is connected to electrical mains by means of a terminal (45-A) of the electrical circuit and three-pin plug (45). A pair of wires (46) from the electrical circuit are connected to an LED (47), seated in a hole (47-A) near bottom end of one vertical side of the lower housing (30).
The hollow, lower housing (30) is enclosed at the bottom by means of a metallic base plate (50), as illustrated in the accompanying drawing # 8. The base plate (50) is constructed of a tin-plated, 1.5 mm thick CRC plate. It has a threaded insert (53) for connecting earth terminal of the mains 3-pin plug (45). It has four embossed legs (51) for additional stability to the anion generator (200). It has four holes (52) for firmly fixing with the hollow, lower housing (30).
