Flatus filtering system with forced air circulation for seats and beds and as wearables

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.

1 . A seat, a pad to be used on seating surfaces, or a wearable pad against buttocks, comprising 1) air pervious elements for buttocks to rest on or against; 2) odor filtering elements; and 3) air sucking elements such as fans for drawing air around buttocks through both said pervious elements and said odor filtering elements. 
     
     
         2 . The device of  claim 1 , wherein air impervious elements are attached to said pervious elements with openings in said impervious elements for said sucking elements to discharge or blow out air. 
     
     
         3 . The device of  claim 2 , wherein said sucking elements are powered by batteries. 
     
     
         4 . The device of  claim 2 , wherein said odor filtering elements are installed at the air intake sides of said sucking elements.
