It will be recognized that some or all of the Figures are schematic representations for purposes of illustration and do not necessarily depict the actual relative sizes or locations of the elements shown. The Figures are provided for the purpose of illustrating one or more embodiments of the invention with the explicit understanding that they will not be used to limit the scope or the meaning of the claims.
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.

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
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.

It is appreciated and understood that the term vaporizer as used herein is exemplary of an inhalation devices that can be used to combust or vaporize liquids, concentrates, waxes, solid materials, herbs, tobacco, and the like.
It is to be noticed that the term “comprising,” used in the claims, should not be interpreted as being limitative to the means listed thereafter. Thus, the scope of the expression “a device comprising means A and B” should not be limited to devices consisting only of components A and B. It means that with respect to the present invention, the only relevant components of the device are A and B. Put differently, the terms “including”, “comprising” and variations thereof mean “including but not limited to”, unless expressly specified otherwise.
Similarly, it is to be noticed that the term “coupled”, also used in the claims, should not be interpreted as being limitative to direct connections only. Thus, the scope of the expression “a device A coupled to a device B” should not be limited to devices or systems wherein an output of device A is directly connected to an input of device B. It means that there exists a path between an output of A and an input of B which may be a path including other devices or means.
The enumerated listing of items does not imply that any or all of the items are mutually exclusive, unless expressly specified otherwise. The terms “a”, “an” and “the” mean “one or more”, unless expressly specified otherwise.
Elements of the invention that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. In addition, elements of the invention that are in communication with each other may communicate directly or indirectly through one or more other elements or other intermediaries.
One skilled in the art will appreciate that the present invention can be practiced by other than the above-described embodiments, which are presented in this description for purposes of illustration and not of limitation. The specification and drawings are not intended to limit the exclusionary scope of this patent document. It is noted that various equivalents for the particular embodiments discussed in this description may practice the invention as well. That is, while the present invention has been described in conjunction with specific embodiments, it is evident that any alternatives, modifications, permutations and variations will become apparent to those of ordinary skill in the art in light of the foregoing description. Accordingly, it is intended that the present invention embrace all such alternatives, modifications and variations as fall within the scope of the appended claims. The fact that a product, process or method exhibits differences from one or more of the above-described exemplary embodiments does not mean that the product or process is outside the scope (literal scope and/or other legally-recognized scope) of the following claims.
