Claim 7:
8. A mixing unit for creating a mixture of a diluent and an additive, as part of the apparatus for dispensing a mixture of a diluent and an additive for sanitation, cosmetic, or cleaning applications, the apparatus comprising:
a mixing unit for creating a mixture of the diluent and the additive,
a diluent supply supplying the diluent to the mixing unit,
an additive supply supplying the additive to the mixing unit, and
an outlet for dispensing the mixture,
wherein the apparatus adds the additive to the diluent in a pulsed manner, the mixing unit comprising:
a diluent inlet and an additive inlet and a mixture outlet;
a moving element with at least one cavity;
the moving element being arranged to be moved at least from a first position to a second position;
wherein, in the first position, the at least one cavity is in liquid communication with the additive inlet and not in liquid communication with the mixture outlet, and in the second position, the cavity is in liquid communication with the diluent inlet and the mixture outlet,
and wherein the moving element in combination with a body relative to which it moves forms a liquid-tight barrier between the additive inlet and the diluent inlet, and between the additive inlet and the mixture outlet.
