Dualcheck valve manifold 40 initially has aninlet check valve 41 separating circularinner cavity 82 frommouthpiece plenum 32. Accordingly, in the inhale function, air is permitted up through theinner cavity 82 of thedevice 10 but not back down through the center in the exhale function. Instead, exhale is diverted to a rear of the device viaoutlet check valve 42, and then subsequently through a plurality offilter nozzles 51 for introduction to thefilter medium FIG. 2F .Filter nozzles 51, especially, provide an aerodynamic manipulation reducing vapor and harmful particulate. - Still further regarding
FIG. 2F , a cross-sectional view is provided depicting thefilter 20 as seen alongline 2F-2F inFIG. 2B . As shown,multi-port manifold 50 aligns a series offilter nozzles 51 in a line. The user exhale exits thenozzles 51 and enters theHEPA filter medium 75. Additional pollutants are removed as exhale exits the HEPA medium and enters the extrudedcarbon filter element 70 having a plurality ofchannels - As stated herein, gaseous and/or particulate pollutants are filtered especially through the novel extruded
carbon layer 70. Heretofore, comparable filters used granulated carbon that greatly impeded air passage therethrough. The extrudedcarbon 70 is able to be molded and shaped to the fine details as required that may includetiny channels carbon 70 is baked to set and cure the material. -
FIG. 3A illustrates an isometric view of an extrudedgraphite filter 70 of the present invention.FIG. 3B provides a slightlydifferent alternative 73. It should be appreciated that the uniquecurved geometry 71 allows enhanced air flow in the exhale function (while remaining compact in size) as compared to any comparable prior art devices that contain granular carbon, or graphite powder as a filtering device. - Also regarding
FIG. 3A ,channels 72 have been enlarged to revealsquare geometry 72 in a top plan aspect. Accordingly, a matrix plurality ofchannels 72 fills out a top surface of thecarbon filter element 70. In a preferred embodiment, the squares measure ½ mm across.FIG. 3B introduces a slightly different geometry with circular 73 channels. - Many alterations and modifications may be made by those having ordinary skill in the art without departing from the spirit and scope of the invention. Therefore, it must be understood that the illustrated embodiments have been set forth only for the purposes of example and that it should not be taken as limiting the invention as defined by the following claims. For example, notwithstanding the fact that the elements of a claim are set forth below in a certain combination, it must be expressly understood that the invention includes other combinations of fewer, more or different elements, which are disclosed above even when not initially claimed in such combinations.
- While the particular Electronic Filter Assembly herein shown and disclosed in detail is fully capable of obtaining the objects and providing the advantages herein before stated, it is to be understood that it is merely illustrative of the presently preferred embodiments of the invention and that no limitations are intended to the details of construction or design herein shown other than as described in the appended claims.
- Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalently within the scope of the claims. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements.
