1. A percolating steeper, comprises a carafe, a cover body, a filter layer, an isolating layer and a control element;

  • the circumferential rim of the said isolating layer is disposed with a tight unit to contact the carafe;

    at least one free moving non-return unit and one passive non-return unit are disposed on the isolating layer;

    the said control element indirectly controls the downward or upward movement of the isolating layer and the filter layer by means of the passive non-return unit;

    both the free-moving non-return unit and the passive non-return unit comprise a cover body with holes;

    a valve body is situated at the valve door on the isolating layer;

    the valve door penetrates through the isolating layer by means of a valve hole;

    the tight unit of the isolating layer and the tight point of the carafe are higher that the lowest feed water surface in the lower aspect of the isolating layer used for conducting the liquid into the valve hole;

    through this elevation difference, the visual effect of air isolation is obviously generated when the substance and the infusion is separated.
