DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS It is to be understood that the invention is not limited in its application to the details of construction or the arrangement of components set forth in the following description or illustrated in the drawings. The invention is susceptible to other embodiments and can be practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.

[0018] Turning now to the figures for purposes of illustration, in FIG. 1, generally illustrated at 10 is a portable and rechargeable personal ionic air purifier 10 of the present invention. Purifier 10 includes a wearable housing subassembly, generally designated 12, of materials, weight, construction, and dimensions adapted to be comfortably worn and / or carried by oneself without any significant encumbrance. An ion emitter subassembly, generally designated 14, is removably mounted to wearable housing subassembly 12 in a manner to be described. Ion emitter subassembly 14 includes carbon brushes 16. A user suspends purifier 10 around their neck using a conductive cord or lanyard 18, which is mounted to wearable housing subassembly 12 in a manner to be described, and turns purifier 10 "on" using a switch, not shown. A cloud of ions, also not shown, is thereby generated from the carbon brush 16 or other ion emitter, also not shown, which is directed towards the facial area, ionizing the personal air space and removing particulates therefrom. These ions attract oppositely charged particles in the air, which are then attracted together towards the nearest ground source. The conductive cord 18 ensures that the ground source is the user's body and not the breathable air stream, thus effectively cleaning the breathable air stream of airborne contaminants and / or generating negative ions.

[0019] The purifier 10 cleans the air of viruses, pollen, smoke, mold, dust mites, and other particulate contaminants, typically cleaning an area of ​​about 3 feet around the head when the purifier is worn around the neck using a lanyard 18. The purifier can also be placed on a nightstand, for example, so that the air around the pillow area is cleansed of contaminants, or located near a table, seat, or any other location where activation and / or purification with negative ions may be desired or required. Arm bands, wrist bands, and the like can be used to mount the device 10 on the body in place of a lanyard in the manner described.

[0020] It is known from U.S. Pat. No. 6,919,053 that a grounded surface in close proximity to a high voltage ion source increases the production of ions. Ideally, an electrical connection is made between the grounded terminal of the high voltage source and the surface. In the case of a personal air purifier, this connection can be achieved through a conductive fabric lanyard that contacts the user's skin. The fabric is ideally constructed of ordinary fabric with interwoven conductive elements. The conductive elements create an electrical connection between the user and one side of the high voltage output circuit output, providing an activation signal at the ionizing potential. The conductivity of the fabric can be achieved using a number of methods, some of which will desirably provide a more comfortable user experience than others. As will appear more fully below, the purifier 10 of the present invention may also employ an ordinary metal necklace, such as one of gold or silver, in a manner as otherwise described.

[0021] The conductive grounding neck strap allows the device to use the body of the person wearing the purifier as a ground source. This has the effect of providing a large ground plane and a significant increase in ion output from the purifier. The strap is generally of cotton construction with layers of interwoven conductive material. It hangs around the neck and / or contacts exposed skin while being directly connected to a floating ground within the device and also to the individual user.

[0022] The ground cord may be constructed from any type of conductive material. A ground plate that contacts the user's body as described may be used in tabletop mount or bed frame, arm or wrist band, or other mount embodiments. Other grounding means may also be employed.

[0023] Referring now to FIG. 2, generally designated at 30, is an exploded cross-sectional view of a portable, rechargeable, personal ionic air purifier according to the present invention taken along line 2-2 of FIG. 1. The wearable housing subassembly 12 includes a battery 32 and a printed circuit board 34 mounted therein. The battery 32 powers an electrical circuit carried by the circuit board 34. The circuit defines an electrical ground and provides an output signal at an ionizing potential. Any suitable electrical circuit for converting battery power to an ionizing potential may be employed to controllably activate the ion emitter 16 to safely emit ions at the ionizing potential, such as the safe and highly efficient electrical circuit shown and described in U.S. Patent No. 9,737,895, which is incorporated herein by reference. A non-rechargeable battery source may also be used for operation of the present purifier.

[0024] The mountable housing subassembly 12 includes a front surface, generally designated 36, having a peripheral wall 38 (shown in best detail in FIG. 1 ) defining a recess, generally designated 40, and a high voltage magnet 42 mounted to the housing 12 flush with the recessed surface 40. A high voltage wire connector 44 connects a signal at an ionizing potential generated by the high voltage circuitry 34 to the high voltage magnet 42. A magnet 46 is mounted to the housing 12 flush with the recessed surface 40 in spaced apart relationship from the magnet 42. A ground plate 48 is mounted to a back surface, generally designated 50, of the mountable housing subassembly 12.

[0025] The ground plate 48 is a conductive material and is electrically connected to a ground potential. The ground plate 48 preferably protrudes so that the ground is easily accessible when the housing 12 is received in an arm or wrist band or other accessory and held in contact with the body. Transferring the ground to another accessory such as a tabletop or bed mount is also an effective method.

[0026] 1 and 2, the ion emitter subassembly 14 includes a generally planar cover member 52 sized to fit within the recess 40 of the mountable housing subassembly 12. An elongated carbon brush wire 54 is mounted to the cover member 52 such that the brushes 16 are exposed at their distal ends at the top of the cover member 52. The proximal end of the elongated carbon brush wire 54 is mechanically and electrically connected by solder or welding 58 to a conductive contact plate 56 of magnetic material which is itself adhesively or otherwise fastened to the inner surface of the cover member 52.

[0027] When the subassembly 14 is inserted into the recess 40 provided therefor in the mountable housing subassembly 12, the conductive magnetic members 42, 46 come into contact with the conductive magnetic member 56. As will be readily understood by those skilled in the art, on the one hand, the ion emitter subassembly 14 is thereby removably attached to the mountable housing subassembly 12 by the action of magnetic attraction existing therebetween, and on the other hand, the ion emitter 16 is activated to an ionizing potential by the completion of an electrical circuit defined between the brush 16, the crimp 58, the conductive magnetic plate 56, and the conductive magnet 42, which are connected via the high voltage wire connector 44 to an ionizing potential at a high voltage output of an ion activation circuit carried by the printed circuit board 34.

[0028] Whenever the carbon brushes 16 become worn out, the ion emitter subassemblies 14 can be replaced by replacement subassemblies by simple convenience of removing one ion emitter subassembly 14 and replacing it with another by magnetic action of engagement and disengagement. The carbon brushes 16 are protected within the recesses 40 from damage due to handling and / or storage.

[0029] While a recess that receives the ion emitter subassembly is presently preferred, other means may be employed to provide the intended alignment of the carbon brush. For example, a magnet mount may provide alignment, or to take another exemplary embodiment, a rounded plate on a rounded body, not shown, may be employed to orient the carbon brush emitter in any desired direction.

[0030] In the presently preferred embodiment, the ion emitter and attachable housing subassemblies 12, 14 each include a magnetic conductive member to provide both removable attachment and completion of the electrical circuit between the carbon brush emitter and the ionization circuit. In alternative embodiments in accordance with the invention, an electrical plug and receptacle or other connection arrangement, not shown, may be provided separately from the magnetic members to complete the electrical circuit. In alternative embodiments in accordance with the invention, different numbers and arrangements of magnetically conductive and / or magnetic members may be provided in any arrangement suitable for removably attaching the ion emitter and attachable housing subassemblies by magnetic action.

[0031] Referring now to FIG. 3, generally designated 70, is a pictorial view of the rear of a portable, rechargeable, personal ionic air purifier in accordance with the present invention. An elongated conductive member 72 is attached to the rear 50 of the wearable housing subassembly 12 and is electrically connected to electrical ground. In the presently preferred embodiment, the elongated conductive member 72 is shaped to provide a resilient, conductive jaw that is external to the housing 12 at ground potential, although this may be configured differently without departing from the concept of the present invention. The lanyard 18 is captured by the conductive member 72, which is also electrically grounded because the conductive member is electrically grounded, which establishes the user's body, not shown, at the same potential as ground potential when the lanyard 18 is worn around the neck. The lanyard 18 is removed as easily as it is inserted into the resilient jaw.

[0032] The lanyard 18 can be a simple loop of conductive material, since special plug ends and mating plugs are not required. The lanyard 18 can also be, for example, the user's own silver and / or gold neckwear. The resilient jaws provided by the conductive member 72 of the present preferred embodiment are capable of receiving clothing between it and the facing surface 50 of the wearable housing 12, which allows for the portable and wearable housing 12 to be mounted on clothing, such as a T-shirt or sleeve or other clothing, not shown. When clothing of any variety is removably received by the resilient jaws provided by the conductive member 72, the ground plate 48 contacts the facing portion of the surface of the user's body, which establishes the user's body, not shown, at the same potential as ground potential. Clothing is removed as easily as it is inserted into the resilient jaws provided by the conductive member 72. The conductive member can be variously configured to removably grip the lanyard and / or clothing without departing from the concept of the present invention.

[0033] The grounding plate 48 in alternative embodiments may be employed to transfer the ground to a desktop mount or bed stand, or may further be used in conjunction with a wrist band, or arm band, or other device for attaching the wearable housing to an intended body part, all not shown.

[0034] 4A, generally designated 90 is a front pictorial view of a portable, rechargeable, personal ionic air purifier 10 with an exemplary decorative surround, generally designated 92, of silicone or other soft or other material in accordance with the present invention. The decorative surround 92 can be made colorful and molded to resemble a bear, as shown, or any desired shape, or to define a logo, or to bear a pattern or graphic, or to have textual features. A colorful, aesthetically molded silicone or other surround makes the device more appealing to various populations, such as children, and the surround can also serve as a marketing tool.

[0035] Decorative enclosure 90 has an open front side and a back side, generally designated 94 and 96 (shown in best detail in FIG. 4B ). Open front side 94 allows access to removable emitter brush subassembly 14. Open back side 96 does not interfere with external grounding provided by clip 72, lanyard 18, or ground plate 48.

[0036] As will be readily understood, the combination of lettering and graphics on the front of the cover member 52 of the ion emitter subassembly 14 and the shape and color and information content of the decorative surround 92 may be integrated, cooperable, or independent without departing from the concept of the present invention.

[0037] Many modifications of the disclosed embodiments will be apparent to those of ordinary skill in the art without departing from the inventive concept thereof.
