Splash and odor reduction in dry toilet

Abstract

This application describes a splash-proof odor reducing waterless toilet, a funnel-shaped soft passageway, the passageway material being a high polymer, and a rim. Below said sim, Passageway is connected to rim. The user's excreta fall onto passageway, and the dirt and dirty liquid will not splash, reducing the size of the path for odors, mosquitoes and flies to come out.

1 . A splash-proof odor reducing waterless toilet, comprising:
 a funnel-shaped soft passageway, hereafter referred to as passageway, the material of said passageway being high polymer;   a rim;   said passageway is connected to said rim, below said rim, the excreta of the user falls onto said passageway, and the dirt and dirty water will not splash, the said funnel-shaped passageway also reduces the size of the path for odors, mosquitoes and flies to come out.   
     
     
         2 . Based on the splash-proof odor reducing waterless toilet as said in  claim 1 , said passageway may be a upright funnel-shaped passageway or a partial funnel-shaped passageway, or it may be an array of a front funnel-shaped passageway and a rear funnel-shaped passageway in the shape of a feces urine separating toilet. 
     
     
         3 . Based on the splash-proof odor reducing waterless toilet as said in  claim 1 , the position of connection between said passageway and said rim may be the rim inner wall, or the rim outer wall, or it may clamp the rim inner wall and outer wall; the connection method may be adhesive bonding, or thermal fusion, or clamping, or crimping, or adhesive bonding with additional crimping, or thermal fusion with additional crimping, or clamping with additional crimping, or clamping with additional adhesive bonding. 
     
     
         4 . Based on the splash-proof odor reducing waterless toilet as said in  claim 1 , said high polymer material may be soft plastic, or soft rubber, or thermoplastic elastomer, or it may be a composite material of the aforementioned three materials, said composite material may have a sandwich layer or surface layer made of reinforcing fibers.
