It is expected that cannabis oil users will use less times per day but have a longer exhale as compared to tobacco users. Additionally further, the smart personal exhale filter herein could be applicable to traditional smoker applications and e-cigarette user, alike. The system 10 herein further includes an interactive component that allows users to check, retrieve data as well as receive data from third parties.
  • Regarding FIG. 2A together with FIG. 5 cross-sectional view, the invention is a smart personal air filter 20, 30 for filtering exhale comprising: a first inner tubular housing 31 for receiving and containing a plurality of filter components, such as a filter cartridge 24, 34 containing carbon or HEPA (high efficiency particulate air) filter, for example; a mouth piece 23 configured to a proximal end of the first tubular housing, the mouthpiece for introducing the exhale. Additionally the air filter 20, 30 comprises a an air instrument 15, or two, for sensing air flow (or air pressure) within the first tubular housing 31; and an electronic transmitter 12 (or transceiver) for sending data to a wireless network provided by the air instrument 15, the data to be for the purpose of monitoring filter performance (e.g. the data to be received by a receiver in a cellular telephone 99); and a power supply 13 for powering said personal air filter.
  • Also regarding FIG. 5, arrows show the movement of air through the device downward. At a proximal end of the inner housing 21, 31 is top end wall 27, 37 providing support at an interface between the mouthpiece 23, 33 and the inner housing 21, 31. Check valve 12 allows air flow in a downward only direction during a user exhale. It should be appreciated that inlet sensor 15 (if employed FIG. 2A) can be configured immediately before the check valve 25 or after. Similarly, check valve 25 can be incorporated to top end wall 27 or sit down in the hole provided by top end wall 27. Exit vent 29, 39 is provided opposite to top end wall 27, 37.
  • 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 Smart Personal Air Filter 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.
