DETAILED DESCRIPTION OF THE INVENTION
(17) FIG. 1 is a front elevational view of a personal health device 100, which has a housing 10 and an air outlet portion 30. The housing 10 includes an upper front panel 11, a lower front panel 12, a side panel 14, a lower panel 16, a top panel 18, and a pair of extending connector portions 50 (only one of which is visible in FIG. 1). A filter 32 is disposed in the air outlet portion 30, for filtering air.
(18) In FIG. 1, the air outlet portion has an angled lower panel 34. The air filter 32 fits through a slot (unnumbered) in the side wall 14. The opposite side wall is similar to side wall 14, and therefore the air filter is supported in two opposed slots in the opposed side walls.
(19) A compartment 40 is disposed on the rear of the device 100, which serves as a compartment for pills, tablets, capsules, and the like, which are typically used for medications. Also, support members 42 and 44 are visible, which are parts of a structure (shown in FIG. 7) used for receiving a personal medications log 88 (also shown in FIG. 7).
(20) A CO detector disk 20 is provided which changes color when exposed to CO gas. The CO detector disk 20 is supported by the lower front panel 12, a wall 24 connected to the panel 12, and a transparent cover portion 22. The CO detector disk 20 is removable from an opening at the top which is not bounded by the wall 24. Any known type of CO detector material can be used for the CO detector disk 20. In a preferred embodiment, the CO detector disk 20 is yellow in a normal condition, and changes color to black when CO is detected.
(21) FIG. 2A is a side elevational schematic view of the device 100 of FIG. 1 providing an air supply 300 to the face of a user. The air supply 300 is seen as providing an air curtain in front of the mouth and nose of the user, tending to keep unfiltered air away and providing filtered breathing air to the user. In FIG. 2A, the device 100 is supported on a chain (unnumbered), though it is also contemplated that a strap, string, or other supporting member can be used to provide a convenient way for the user to carry the device 100 is a position suitable for use.
(22) FIG. 2B is a front elevational schematic view of the device of FIG. 1 as worn by a user, as described above with reference to FIG. 2A, for providing an air supply to the face of a user.
(23) FIG. 3 is an elevational view of the device of FIG. 1 showing a rear side of the device. The compartment 40 has been described in the above, and further includes a latch portion 48 and a sidewall 46. The personal medications log 88 (also shown in FIG. 7) is shown for insertion into a support portion formed by the portions 42 and 44 which are connected by a bottom portion (unnumbered).
(24) FIG. 4 is an assembly view of the device 100 of FIG. 1. In this view, like numbered elements as in FIG. 1 are as described above. Additionally, FIG. 1 shows a fan 60, a power source 400, and air passages 62, 62. The fan 60 can be a pad fan, for example. The air passages 62, 62 are merely schematic, and in practice, a greater number of such air passages would usually be provided, which may be smaller or larger than those shown, and which may be located in places other than or in addition to those shown. All such variations would be within the ambit of skill of any one having skill in the fan and fan housing arts, and all such variations are contemplated as being within the scope of the present invention.
(25) Other elements and features are shown in FIG. 4. The filter 32 is shown separately, and a solar panel 410 (which is optional) is disposed on top of the housing. The solar panel may be used to power the fan, or to act as a booster to extend battery life in use, or as a way of recharging the battery 400 when the device 100 is not in use. It is noted that an ON-OFF switch is not shown, and such ON-OFF switches are very well known. The ON-OFF switch is therefore omitted for the sake of clarity. It would be conventional to provide and use such an ON-OFF switch at any convenient location, and all such variations are considered to be within the scope of the present invention. The device 100 can also be turned OFF by manually removing the battery 400.
(26) A UV light source 420 is schematically depicted in this view, being connected by a pair of wires (unnumbered) to a power supply. A battery 400 is shown, having two connecting wires 401 and 402 schematically shown being connected with the based of the fan 60, for supplying power to the fan 60. The fan 60 itself is contemplated as being a conventional bladed fan.
(27) The UV light source 420 is provided to purify and sterilize air, by emitting UV light on air that is being urged by the fan 60 toward the filter 32. The UV light source 420 is optionally included, and when so included it is contemplated that interior surfaces of the housing have a UV-reflecting coating or are composed of UV-reflecting material, to enhance and improve the effectiveness of the UV light. While a single UV light source 420 is shown and positioned in FIG. 4, it will be understood that this is for illustrative purposes, and in practical use one or more such UV light sources can be provided, and their locations selected for improved effectiveness. It will be understood that all such variations would be within the ambit of skill of any one having skill in the art of UV light sources for use in purifying air.
(28) In the following, it will be understood that different types of fans and housings can be used, and different types of materials, power sources, and filter types can be used. All such variations would be within the ambit of skill of anyone having skill in the fan and fan housing arts, and all such variations are contemplated as being within the scope of the present invention.
(29) Additionally, materials, paints, and colorings can be varied. Power sources can also be varied, including disposable batteries, rechargeable batteries, high capacity cell phone batteries, solar-power films and/or panels, solar-rechargeable batteries, and so on. The position and number of the air holes can be varied, the number and placement of UV light sources can be varied, and the location of the CO detector can be varied. All such variations are contemplated as being within the scope of the present invention.
(30) FIG. 5 is a side elevational view of the device 100 of FIG. 1 as viewed from the right. The air flow path is schematically illustrated in this view.
(31) FIG. 6 is a front elevational view of the device 100 of FIG. 1.
(32) FIG. 7 a rear elevational view of the device 100 of FIG. 1.
(33) FIG. 8 is another embodiment of the device 100, having a top air flow opening 103 and a top edge 102. In this embodiment, it is contemplated that the interior would be similar to that show in FIG. 4, but the fan 60 would be a sideways fan like a laptop computer fan, to push air out of the top of the device 100.
(34) FIG. 9 is a rear elevational view of the device 100 of FIG. 8.
(35) FIG. 10 is an assembly view of the device 100 of FIGS. 8 and 9.
(36) FIG. 11 is side elevational view of the device 100 of FIG. 8 as viewed from the right.
(37) FIG. 12 is a front elevational view of the device 100 of FIGS. 8-11.
(38) FIG. 13 is a rear elevational view of the device 100 of FIGS. 8-11.
(39) FIG. 14 is a schematic side view of a tiltable air outlet portion usable in the embodiment of FIGS. 1-7. The tiltable portion uses a pivot 70 to allow pivoting of the air outlet 30 between position A outside the housing 10 and position B inside the housing 10. A side wall 14 of the housing 10 is visible in this view. In this embodiment, the air outlet portion would include a pair of side walls 31 (only one of which is visible in FIG. 14). In this embodiment, the fan 60 would be carried by the tiltable portion and movable therewith, and is omitted from FIG. 14 for the sake of clarity. The pivot 70 can be a bearing or pin, and another such pivot 70 would be disposed on an opposite side from that shown. Tiltable outlets are known for directing air flow, and any such tiltable mechanism can be used which is within the ambit of skill of any one in the air flow control art.
(40) FIG. 15 is a schematic side sectional view of a further embodiment of the present invention, having a UV light guide 80 adjacent to the lower panel 34. The UV light guide 80 is for providing UV light to the filtered air exiting from the air outlet portion 30. The UV light is directed such that it is generally parallel to the filter 32, so that the UV light is directed across the filter 32. Thus, the UV light does not shine outwardly of the device, and the UV light passing across the filter 32 is captured by the opposing portion of the housing 10 that exists opposite to the wall 34. The UV light therefore does not pose a hazard to the user, and the UV light source is safely located within the housing 10 where it is not subject to external impacts or breakage.
(41) The UV light can be supplied, for example, by UV light from the UV bulb 420 shown in FIG. 4, or a separate UV source can be supplied. The light guide 80 can be a hollow mirrored channel, for example, or can be a solid thin material capable of carrying UV light. Alternatively, the light guide 80 can be composed of optical fiber materials bundled so as to form a sheet-like body, and the materials thereof are selected from those suitable for transmitting UV light. It is contemplated that the light guide 80 substantially spans the entire width of the panel 34 that coextends with the filter 34, so as to provide coverage of most or all of the air exiting from the filter 32. Additionally, the UV light can be focused prior to entering the light guide 80, to increase the intensity.
(42) The invention being thus described, it will be evident that the same may be varied in many ways by a routineer in the applicable arts. Such variations are not to be regarded as a departure from the spirit and scope of the invention and all such modifications are intended to be included within the scope of the claims.
