DETAILED DESCRIPTION OF THE INVENTION

In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the vaporizer filter of the present invention. It will be apparent, however, to one skilled in the art that the vaporizer filter may be practiced without some of these specific details. Throughout this description, the embodiments and examples shown should be considered as exemplars, rather than as limitations on the vaporizer filter. That is, the following description provides examples, and the accompanying drawings show various examples for the purposes of illustration. However, these examples should not be construed in a limiting sense as they are merely intended to provide examples of the vaporizer filter rather than to provide an exhaustive list of all possible implementations of the vaporizer filter.


Specific embodiments of the invention will now be further described by the following, non-limiting examples which will serve to illustrate various features. The examples are intended merely to facilitate an understanding of ways in which the invention may be practiced and to further enable those of skill in the art to practice the invention. Accordingly, the examples should not be construed as limiting the scope of the invention. In addition, reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.


Referring now to FIG. 1, shown is a removable filter 100 configured for use in conjunction with an vaporizer such as an electronic cigarette, vaporizer, or vaporizer component such as a pod, cartridge, or the like. The filter 100 is designed to be placed over the end of the vaporizer where the air flow outlet is located. In some embodiments, the filter 100 is configured to be placed over the mouthpiece or mouthpiece-area of such an vaporizer.


The filter 100 includes a housing 101 that has a sidewall 102 and a top 103. A filter element 105 is disposed inside the filter 100 adjacent to the top 103. In some embodiments, a partition 106 is provided on the opposite side of the filter element 105 in order to keep the filter element 105 in place. Thus, in some embodiments the filter element is disposed between top 103 and partition 106


In some embodiments, each of the top 103 and partition 106 includes an aperture 104 to permit air and vapor to pass from the vaporizer and out through the filter 100 into the user's mouth. The aperture 104 can also function as a drainage or blow-out hole for the user to expel from the filter 100 moisture that may build up inside the filter element 105 over time. In other embodiments, the top 103 and/or partition 106 are each generally air-permeable to facilitate airflow. In some embodiments, the interior of the filter 100 includes a lip or race 107 that facilitates a snap fit with an vaporizer as further described herein.


The housing 101 in some embodiments comprises a flexible material such as silicone or the like which permits the housing 101 to confirm to variances in the geometry of the mouthpiece over which it is placed. In other embodiments, the housing 101 is a rigid plastic or resin material that instead of being placed over the mouthpiece of a vaporizer, instead form the mouthpiece itself, which the filter element 105 embedded therein. Such an integrated design could be implemented as a removable mouthpiece element or as a fixed mouthpiece element such as may be the case in a disposable “pod” type vaporizer system. Yet still, in some embodiments, the filter element 105 may be removable and replaceable with respect to the housing 101 so that the housing 101 can be re-used repeatedly simply by replacing the filter element 105.


With reference to FIG. 2, in some embodiments, the filter element 105 of the filter 100 includes an inner element 201 and an outer element 202 concentrically disposed to one another. One or both of the inner and outer elements 201 and 202 may be constructed of microfibers or other materials made of any polyester, polyamides, bamboo, coconut charcoal, wood or cellulose fibers or polymeric material that is capable of absorbing water or vapor, and/or that which is capable of being impregnated with a flavor or chemical compound. In some embodiments, one or both of the inner and outer elements 201 and 202 comprise quartz wool or other micronized forms of quartz which are capable of absorbing heavy metals and other toxins that are present in certain types of vapor emitted from common vaporizers.


In some embodiments, one or both of the inner and outer elements 201 and 202 may comprise filtration and pass through structures having a high surface area for contact with vapor passing there through, enabling the vapor to become enriched with nicotine, cannabinoids, flavors, and other blends, either alone or in combination.


In some embodiments, the outer element 202 may comprise a plurality of axially elongated fibrous filtering material members disposed concentrically to reduce the amount of water vapor carried into the lungs when inhaling vapors from the vaporizer on which the filter 100 is disposed, whether such vapor contains nicotine, cannabinoids, flavor, or medications. In other embodiments, the inner element 201 comprises a section capable of dispensing volatile ingredients including nicotine, cannabinoids, tobacco flavor, medications, and other flavoring. Reservoirs formed therein may be circular or noncircular in cross section. Absorbent material may be used to retain more volatiles within the inner element 201 to better wick the volatile vapors when vapor or air is drawn through the vaporizer. Drawing vapor or air through the inner element 201 transfers vapors to the user. Loading of any material into the inner or outer elements 201 or 202 may be accomplished via sprayer, direct injection or a gaseous atmosphere conductive to preserving nicotine. The fluid mechanic principles of adhesion, cohesion capillary action and surface tension which can cause a thin film may be used. The basic properties, components and applications may be exchanged between the inner and outer elements 201 and 202.


Referring to FIGS. 3A-3D shown are various embodiments of the filter shaped and sized to accommodate the geometry of various types of vaporizers and the mouthpieces thereof. FIG. 3A shows a generally cylindrical shaped filter 100. FIG. 3B shows a generally rectangular shaped filter 100. FIG. 3C shows a generally square shaped filter 100. FIG. 3D shows a generally conical or truncated-conical shaped filter 100.


Referring to FIGS. 4A and 4B shown is an exemplary embodiment of the filter 100 in use in conjunction with an exemplary vaporizer 400. The filter 100 may attached to the vaporizer 400 by interference fit or by snap fit. In some embodiments, the lip 107 engages with the top edge of the vaporizer to facilitate a secure, but removable fitment.


Referring to FIG. 5, another feature of the filter 100 is illustrated. A removable wrapper 500 may disposed around the outside surface of the filter 100, where a user would place their lips when drawing on the vaporizer 400. In some embodiments, a series of sanitary peel-away wrappers 500 are concentrically disposed around the filter 100 and can be removed as desired to provide for a clean surface each time the vaporizer is used. In some embodiments the wrappers 500 are at least partially adhesive and are frangibly separated from one another by perforations, a kiss-cut, or separation line.


Referring to FIG. 6A, shown is an embodiment of the vaporizer filter configured as a removable and replaceable mouthpiece assembly for a vaporizer. Here, filter 600 comprises an outer housing 601 that includes a filter section 602 and a insert tang section 603 extending therefrom. The insert tang section 603 is hollow and is configured to be inserted and seated inside an opening of a vaporizer cartridge or similar vaporizer device. The filter section 602 includes an internal plug 604 oriented at the center of the filter housing 601. A filter element 605 is disposed annularly around the outside of the internal plug 605 and is encased by the sidewall 601′ of the housing 601. Accordingly, the filter elements 605 is disposed between the sidewall 601′ and the internal plug 605. A top 606 seals a portion of the filter section 602 and includes an aperture 607 to permit the passage of air flow out of the filter 600 and into the user's mouth. As shown in FIG. 6B, the filter 600 is seated in the vaporizer cartridge 608 and is in flow communication with the air flow exit thereof. In use, airflow is directed out of the vaporizer cartridge and into and through the insert tang 603. As air flow reaches the bottom of the filter section 602, the internal plug 604 blocks and re-directs airflow outward to the filter element 605 surrounding the plug 604. Accordingly, in some embodiments air flow passes only through the outer annulus, i.e. the filter element 605, and is filtered thereby. Filtered air exits through the aperture 607 of the top 606. The filter element 600 may comprise all of the elements disclosed above with respect to filter element 105.
