The other end of the foam tube 12 is connected to a nozzle 14, and foam is discharged through the nozzle 14. Wherein the length of the foaming tube 12 is between 10cm and 500cm, the inner diameter of the tube is between 0.8mm and 20mm, and the pressure of the liquid-gas mixture in the foaming tube is between 8 PSI and 32 PSI. This arrangement provides sufficient mixing of the air and the solution in the foaming tube 12 for sufficient time, space and liquid-gas mixing conditions to allow for the ejection of a rich foam from the nozzle 14.

In one embodiment, the ratio of the air to the solution in the liquid-gas mixture is between 1:1 and 10. This foam watering can 1 can be used to general common washing occasion, like car wash, glass clean etc. between this gas-liquid mixture proportion, this liquid-gas mixture's mixing uniformity and mobility, foaming multiple are in the preferred state that uses required, can produce abundant, have the foam of certain fineness concurrently, and then ensure the cleanness or the cleaning performance of different demands.
