Abstract
A foam dispensing device creates and dispenses foam from a source of liquid. The device employs a mixing chamber upstream of a unit of porous material and an outlet. When activated, a single motor powers a liquid pump and an air pump. The liquid pump transports liquid from a source to the mixing chamber. The air pump propels air through the mixing chamber wherein the air becomes pressurized. The liquid and air mix within in the mixing chamber. The liquid-air mixture is propelled through the porous material by the flow of air, creating a foam that is dispensed from the outlet.

14. A liquid foam dispenser comprising:
-
a mixing chamber positioned upstream of an outlet and in fluid communication therewith; a unit of porous material positioned between the outlet and the mixing chamber; a liquid channel delivering liquid to the mixing chamber; an air channel delivering air to the mixing chamber; a liquid source positioned upstream of the liquid channel; a first pump adapted to propel liquid from the liquid source through the liquid channel to the mixing chamber; a second pump adapted to propel air through the air channel through the mixing chamber and out the outlet; and a motor in drive communication with the first and second pumps, wherein upon activation of the motor, the first pump and second pump simultaneously propel liquid and air to the mixing chamber, the mixing chamber being adapted to initiate pressurization of the flowing air therein resulting in counter-mixing of the pressurized air with the liquid, and the flowing air propels the liquid-air mixture through the unit of porous material to form a foam that is discharged from the outlet. - View Dependent Claims (15, 16)

17. A liquid foam dispenser, comprising:
-
a liquid storage unit having a receiving unit with an inlet and a removable liquid reservoir releasably engagable with the receiving unit, the reservoir having an outlet aligned substantially with the receiving unit inlet when the reservoir and receiving unit are engaged; a mixing chamber positioned between an outlet and the liquid storage unit and in fluid communication therewith; a unit of porous material positioned between the outlet and the mixing chamber; a liquid channel delivering liquid from the liquid reservoir to the mixing chamber; an air channel delivering air to the mixing chamber; a first pump adapted to transport liquid from the reservoir through the liquid channel to the mixing chamber; a second pump adapted to propel air through the air channel, mixing chamber and outlet;
whereinupon activation of the motor, the first pump and second pump simultaneously propel liquid and air to the mixing chamber, the mixing chamber being adapted to initiate pressurization of the flowing air therein resulting in counter-mixing of the pressurized air with the liquid, and the flowing air propels the liquid-air mixture through the unit of porous material to form a foam that is discharged from the outlet. - View Dependent Claims (18, 19)
