A water vapor relief device for domestic coffee makers includes one tube connected to a vapor generator of the coffee maker and terminating at a free end thereof with an outlet hole and another tube which surrounds the first tube and forms therewith a chamber. The first tube at the end thereof carries an expanded head for a nozzle. A conduit formed between the nozzle and the head is inclined to produce the Venturi effect so that in the liquid such as milk in which the device is submerged the bubbling is produced which generates a foam.

A water vapour relief device for domestic coffee makers, comprising a first tube connected to a vapour generator of the coffee maker, said tube having a free end terminating in a small outlet hole through which said vapour emerges to the outside, a second tube coaxial with and surrounding said first tube to define therebetween a chamber provided with a hole for admission thereinto of surrounding air, and an auxiliary conduit located close to the outlet hole of the first tube and inclined such that the water vapour, due to an outlet pressure thereof, generates, through the Venturi effect, a suction on said auxiliary conduit, such that the device as a whole supplies a mixture of water vapour and air which creates, in a liquid wherein the device is submerged, such as milk, the bubbling which generates a foam.
