Directional fluid inlet
A fluid inlet portion for a waterless urinal cartridge is presented. The fluid inlet portion comprises to fluid director comprising a non-linear surface proximate a throat portion of the cartridge formed to impart a horizontal velocity component to fluid flowing through the throat portion of the cartridge to reduce vertical turbulence within the fluid. The fluid director can be formed so that it is in fluid communication with at least part of a fluid layer within the cartridge. The non-linear surface imparts a horizontal velocity component, thereby reducing disruption of the fluid layer by fluid flowing through the throat portion of the cartridge. The fluid director may be positioned within the cartridge to impart a substantially horizontal swirling motion to fluid within the cartridge. A fluid deflector proximate the fluid director can receive fluid from the fluid deflector and for re-directing the fluid from the fluid director.
1. A waterless urinal cartridge, the waterless urinal cartridge comprising:
an inlet for receiving urine;
an inlet compartment;
a throat portion residing between the inlet and an inlet compartment;
a cartridge side wall surrounding the inlet compartment;
a curved fluid director extending from a top of the inlet compartment and into an area of the inlet compartment directly below the throat portion,
wherein the curved fluid director is formed for receiving the urine from the throat portion and gradually directing the urine with a horizontal velocity component toward a portion of the cartridge side wall,
wherein the curved fluid director extends in a direction substantially parallel with a top and a bottom of a barrier fluid layer residing therein.
2. The waterless urinal cartridge as set forth in claim 1 , wherein the curved fluid director is formed such that it is in fluid communication with at least a portion of the barrier fluid layer residing therein.
3. The waterless urinal cartridge as set forth in claim 2 , where the curved fluid director is configured to direct urine flowing through the throat portion beneath the barrier fluid layer in a substantially uniform direction.
4. The waterless urinal cartridge as set forth in claim 1 , where the curved fluid director comprises a surface-type selected from a group consisting of convex and concave.
5. The waterless urinal cartridge as set forth in claim 1 , wherein the curved fluid director is formed to gradually change a direction of the urine received from the throat portion.
