Abstract
A foam spray can comprises a motor pump, a foaming tube and a nozzle. The motor pump can be used to suck air and solution and pump out the liquid-gas mixture. One end of the foaming tube is connected to the motor pump for transmitting the liquid-gas mixture pumped by the motor pump and fully mixing the air with the solution to produce foam. The nozzle is connected to the other end of the foaming tube to spray foam. The length of the foaming tube is between 10 to 500 cm, the tube inner diameter is between 0.8 to 20 mm, and the pressure of the liquid-gas mixture in the tube is between 8 to 32 PSI, thereby to provide sufficient time, space and conditions for the mixing of the air and the solution in the foaming tube to fully mix the air and the solution, and then to spray abundant foam from the nozzle.
