<p>The liquid dispenser comprises a body (1) connected to a bottle (2) and to a zone of calibrated volume (8) through conduits (3, 4 et 6), by means of a slide valve (10) which moves in a duct (5), allowing or preventing such communication. The zone (8) is also connected to an outlet mouthpiece (9) through chamber (9a), and through the slide valve (10) so that communication with the bottle (2) can take place only when the outlet mouthpiece (9) is closed. In the same way, opening of said mouthpiece (9) can take place only after the closing of conduits (4 and 6). Conduits (11, 12, 13 and 15) are provided at the highest portion of the zone (8) to provide for air movement necessary for complete filling and emptying. The slide valve (10) is actuated be means of an offset finger (17) driven by a geared motor (19) controlled by the control block (24) comprising a microprocessor and programmable memories and connnected to an external power source, and detection assemblies (25, 20 and 21).</p> |
