Smoking Instrument Personal Air Filter

Abstract

As an accessory and in combination to a smoking instrument such as a traditional cigarette, a personal air filter filtering exhale and intermittent smoke emissions, is disclosed. The device is broadly a housing providing a semi-enclosure having a mouthpiece coupled thereto, the mouthpiece including dual check valve technology for an inhale and a reverse exhale function. Separate or multi-directional filters are provided for the exhale function, and also for filtering intermittent emissions occurring between user intakes. The configuration and filter technology herein, seeks to improve air quality in enclosed spaces, additionally further by minimizing or eliminating second hand smoke.

Description

PRIORITY CLAIM[0001]This patent application claims benefit of the priority date of U.S. Prov. Pat. App. Ser. No. 63 / 061,330 filed Aug. 5, 2020 entitled “Smoking Instrument Personal Filter.” Accordingly, the entire contents this U.S. provisional patent submission is hereby expressly incorporated by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention pertains generally to smoking instruments comprising a thin paper cylinder, such as a tobacco cigarette or machine rolled medical cannabis or CBD cigarettes. More specifically, the present invention relates to an exhale and / or ambient filter for such instruments.Description of the Prior Art[0003]Smoking tobacco or other plant material has notoriously been practiced in numerous cultures for many centuries.

AI Technical Summary

Benefits of technology

The present invention is a smoking instrument filter assembly that can filter in two directions separate sources of smoke. The filter system has different pairs of filters that make up the two filter streams. The invention also includes a mouthpiece with check valve technology. The filter stream channeling is unique and increases velocity, breaks up laminar flow with veins and direction changes, and provides increased travel time and distance in a compact device. The technical effect of this invention is to provide a more efficient and effective smoking experience with improved air quality and reduced health risks.

Problems solved by technology

One challenge to designing a filter solution is that it should completely eliminate smoke emitting from the device as any small smoke emission will be noticeable to people sensitive thereto, especially in an airline flight environment or similar enclosed space or building lacking adequate ventilation.
