Abstract:
A dispensing device, including a housing, a first connection to connect to a water source, a second connection to connect to a gas source, a formula reservoir, a mixing zone, a deposition zone, a circulation zone configured to circulate the water and the gas from the deposition area to the mixing zone, a valve connected to the deposition zone, configured to release the gas and water into the formula reservoir, a first temperature sensor to sense a first temperature when water and the gas enter the mixing zone, a second temperature sensor to sense a second temperature when water and gas enter the deposition zone, and, when a predetermined temperature is reached, direct the valve to open, and an opening coupled to the formula reservoir configured to deposit a mixture of one or more formulas, gas, and water.
