Problem Statement
- Existing technology in market for automatic flushing of urinals requires electricity for operation which make them unsuitable for use in large scale public toilets where power sources are limited.
- Low pressure heads for flushing creates unhygienic conditions.
- There exists a need for an automatic flusher that does not use electric power and flushes right amount of water in an affordable and simple manner.
Technology
- A hinged foot plate biased against one or more springs below it and adapted for angular displacement in response to the pressure on the foot plate on which the user stands
- flushing mechanism comprising of a cylinder having an inlet and outlet enclosing two pistons, an upper piston and a bottom piston through a connecting rod
- Upper piston biased against a spring positioned between the upper piston and the cylinder cap, and an one-way valve to allow air inside the cylinder
- The transmission means acts as a link between the actuator and that of the flushing mechanism
Key Features / Value Proposition
- The automatic flusher uses a damping mechanism, which can be fit in existing plumbing pipes as an add-on reducing installation costs compared to conventional automatic flushers that require additional fixtures such as flush tanks.
- Floorboard can be placed within the floor to improve aesthetic appeal of the product
- Base plate designed to cause substantial displacement for even small children.
- Amount of water flushed can be controlled thereby helping in conservation of water compared to conventional urinals which have constant flush volumes depending on size of flush tank or use excess water due to user-controlled valves.
- The flushing mechanism uses no electricity enabling its use in large scale public toilets in remote areas.
