Benefits of technology

[0008]This invention intends to help people to achieve farting freedom by efficiently filtering flatulence odor using forced air circulation. The portable air filtering system of this invention, built into a seat or a bed, as a pad on a seat or a bed, or as a wearable, consists of an air pervious element such as mesh or cloth for buttocks to rest on, an odor filtering element such as active carbon, and an air sucking element such as fans. The suction by the fans draws the air arou

Problems solved by technology

A few of the articles provide means to force the flow of flatulence gas but they are either too clumsy to be practical or too awkward and too inconvenient to be useful.
There is no forced air circulation in the above devices; therefore there is no guarantee that flatus gas would go through the protective devices to be filtered.

second embodiment

[0019]FIG. 2 shows the invention as a bed pad, with the arrows indicating directions of forced air movement. This bed pad consists of the same elements as the seat pad shown in FIG. 1. Therefore the discussion for FIG. 1 in the above paragraph also applies to FIG. 2.

third embodiment

[0020]FIG. 3 shows the invention as an integral part of a seat, with the arrows indicating directions of forced air movement. The air pervious layer 10 is the seating surface of the seat. An optional air pervious cushion layer 22 can be added below the air pervious layer 10 for comfort or sound attenuation, or both. An optional structural support layer 24, as mesh or perforated material, can be added below the optional cushion layer 22 to support seating weight. For seats without the optional cushion layer 22, the optional structural support layer 24 is no longer needed as the air pervious layer 10 can be made strong enough to serve as structural support for seating weight by using strong mesh or perforated material such as wood, plastic, metal, etc. The air impervious layer 14 is attached to the optional structural support layer 24 or directly to the air pervious layer 10. The fan 12 is attached to the air impervious layer 14 and blows out air through an opening in 14. The odor fil...

fourth embodiment

[0021]FIG. 4 shows the invention as an integral part of a seat, with the arrows indicating directions of forced air movement. The air pervious layer 10 does not cover the whole seating surface but only a small area under the anus location of a seated person. The fan 12 is about the same size as the small area of layer 10 and can draw air through this small area efficiently without the help of the impervious layer 14. Other than the small area and the lack of the impervious layer 14, this embodiment is similar to that shown in FIG. 3.

Abstract

This invention is a portable air filtering system with forced air circulation. It is built into a seat or a bed, as a pad on seats or beds, or as a wearable pad against buttocks. It consists of an air pervious element such as mesh or cloth for buttocks to rest on or against, an odor filtering element such as active carbon, and an air sucking element such as a fan. The suction by the fan draws air around buttocks through both the air pervious element and the odor filtering element. To increase efficiency of suction and to prevent flatulence gas from escaping, an air impervious element is used so that only the air around buttocks is drawn into the odor filtering element. This portable, nonintrusive, and convenient odor filtering system reliably removes flatulence odor and can give people the freedom of farting without causing offensive malodor for others and themselves. Additionally, the rotation of the fan can be reversed to blow air to, instead of sucking air from, the buttock area for cooling purpose, with a valve allowing air to bypass the odor filtering element for efficiency.

Description

TECHNICAL FIELD[0001]This invention relates to a portable air filtering system with forced air circulation for seats and beds and as wearables for efficiently and reliably removing flatus odor.BACKGROUND ART[0002]Many articles have been invented to address flatulence odor. Most of the articles provide no means to force flatulence gas to flow downward into their intended elements, as flatulence gas normally spreads, predominantly in the upward direction. A few of the articles provide means to force the flow of flatulence gas but they are either too clumsy to be practical or too awkward and too inconvenient to be useful.[0003]Representative articles to address flatulence odor are described below. They can be grouped into four groups: wearables, pads, containers, and articles with forced air circulation.[0004]Many protective devices against flatulence odor were wearables, such as: anal napkin, U.S. Pat. No. 2,742,042 issued to Flanders on Apr. 17, 1956; anal filter, U.S. Pat. No. 4,182...
