The foam generating device and foam generating method of the present invention can effectively reduce the failure rate of the equipment, simplify the structure of the equipment, reduce the manufacturing cost, save the cumbersome steps of mixing and diluting water and liquid in advance, and make the use more convenient.

Description

technical field [0001] The invention relates to the technical field of foam machines, in particular to a foam generating device and a foam generating method. Background technique [0002] Foam generating device, also known as foam generator, is a device that uses foaming agent aqueous solution to make foam. There are two necessary factors for the formation of foam, one is foaming agent solution, and the other is air, both of which are indispensable. , there is no blowing agent solution, the liquid film surrounding the gas will not form, and there will be no bubbles, and there will be no gas, and the foaming agent solution alone will not form bubbles. [0003] At present, the foam generating devices on the market are roughly divided into two categories: the first type is to pump liquid through a liquid pump, and then combine water and air pump to generate foam. The disadvantages of this type of device are complex structure and high manufacturing cost. , and after the liquid ...

[0003] At present, the foam generating devices on the market are roughly divided into two categories: the first type is to pump liquid through a liquid pump, and then combine water and air pump to generate foam. The disadvantages of this type of device are complex structure and high manufacturing cost. , and after the liquid suction pump pumps the foam liquid for a long time, due to the viscosity of the foam liquid itself, it is easy to cause the diaphragm inside the liquid suction pump to be stuck, resulting in the failure of the liquid suction pump to continue to work normally, resulting in a high failure rate of the equipment; The first method is to dilute the foam liquid and water in a certain proportion, and directly use the liquid-air mixing pump to generate foam. The disadvantage of this method is that the water and foam liquid need to be mixed and diluted in advance, so under the premise of the same container, it will As a result, the number of times of use is too low, and the mixture needs to be frequently added for deployment. The operation process is cumbersome and extremely inconvenient to use.
