PERFORMANCE SAFETY DEVICE UNIT FOR A PURIFICATIO APPARATUS

The present invention relates to a fluid purification system, more particularly to indicate the end of performance of the said purification system with a magnetic lock mechanism to prevent water flow after service life of the purification cartridge. The said purification system comprises a water inlet unit, a cartridge unit further comprising a sediment filter, activated carbon and disinfection media or contaminant removal media and a water outlet. The said system is either connected to source water or placed in gravity filtration system with a top container for source water and bottom container for purified water. The cartridge housing of the cartridge unit comprises a stopper, a stopper holder, magnets, a disintegrating chemical composition and a meshed metal base. The Stopper unit is a plunger and further comprises the said magnet attached to the edges of the stopper. The said stopper holder of the cartridge housing functions to hold the stopper with the magnet within the cartridge housing. The said disintegrating chemical composition of the cartridge housing is a water soluble tablet, a water-erodible tablet, or a combination thereof. The disintegration of the chemical composition is proportional to the life of the purification media or cartridge. The complete dissolving of the cartridge moves the stopper via magnetic forces of attracting towards the metal base and blocks the outlet of the water to the storage tank. The purification system of the present invention, though not specifically described for operation in any particular applications, is used in domestic, industrial or the like to ensure purification of water is not performed beyond the life of the cartridge.
