Liquid dispenser with a discharge head

A liquid dispenser comprising:

• a base unit with a liquid reservoir for receiving liquid;
• a discharge head comprising a housing connected to the base unit;
• and
• a pump device configured to be actuated by a relative translatory movement of the discharge head relative to the base unit and that conveys liquid out of the liquid reservoir into the discharge head or the liquid reservoir is configured as a pressure accumulator and the liquid dispenser has a valve device configured to be actuated by a relative translatory movement of the discharge head relative to the base unit and conveys liquid out of the liquid reservoir into the discharge head;
• the discharge head having a liquid outlet through which liquid is discharged from the liquid reservoir out of the discharge head;
• the discharge head having a liquid inlet through which liquid is conducted out of the liquid reservoir to the liquid outlet;
• the discharge head being configured for selectively discharging liquid either as an atomized spray jet and as a non-atomized liquid stream or individual droplets;
• the discharge head including an outlet channel having an inner surface wall and an internal part inside the outlet channel, the internal part having an outer surface facing the inner surface wall of the outlet channel;
• the internal part including a spray duct ending at a spray opening on a front face of the internal part;
• the internal part and the outlet channel being relatively displaceable so that in a first relative position, a bypass duct is produced between the inner surface wall of the outlet channel and the outer surface of the internal part, and in the first relative position, a first relative position bypass flow resistance of the bypass duct is lower than a first relative position spray duct flow resistance of the spray duct, and the bypass duct and the internal part have a second relative position wherein a second relative position bypass flow resistance of the bypass duct is higher than a second relative position spray duct flow resistance of the spray duct;
• and
• wherein the liquid flowing through the bypass duct bypasses the spray duct and the spray opening;
• and
• wherein the spray opening moves linearly relative to an outlet opening of the outlet channel.
