Abstract
An exemplary foam dispenser system includes a housing, a container, a motor, an air pump, a foam pump, a first mixing chamber, a second mixing chamber, a foam cartridge, and an outlet for dispensing foam. The container holds a foamable liquid. The foam pump has a liquid pump portion that pumps liquid, and an air pump portion that pumps air. The first mixing chamber is located downstream of the liquid pump portion and the air pump portion, and the liquid and the air mix in the first mixing chamber to create a first foam mixture. The second mixing chamber is located downstream of the first mixing chamber and the air pump, and the first mixture and air from the air pump mix in the second mixing chamber to create a second foam mixture. The second foam mixture travels through the foam cartridge and exits the outlet as rich foam.
