Bubble generator

The utility model relates to a kind of gas, two kinds of materials of liquid mix, and generates the bubble generator of bubble.

Almost everyone plays over-blowing recreation lathery, get a short tube, in filling the container of liquid soap, dip in liquid, make the mouth of pipe form liquid film, blow with mouth from the other end of pipe, the mashed soap bubble of seven variegation just occurs, this arm and container are exactly the simplest bubble generator, but this ancient and simple device does not have other practical value except that being used as toy.

In fact, for a long time, the mankind make unremitting effort to the technological improvement of bubble generator, progressively are applied aborning.The third phase in 1971 " metallurgical security " is translated the bubble generator that is loaded with pass " waterpower injection type foaming machine ", its objective is and utilize this device to produce foam continuously in a large number, suppress mine dust, its structure is a control valve, water jet fan with the foam that power grid is made net takes place connects, and then the expanding foam solution case is communicated with water jet fan with pipeline, its foam theory is, air-flow through the control valve adjusting, in the aqueous vapor injector, produce negative pressure, draw the liquid and the atomizing of expanding foam solution case, because the effect of air-flow, vaporific liquid is splashed on the foam generation grid, form liquid film in the grid gap, air-flow blows liquid film and swashs into foam, and foam is used for suppressing mine dust.This device has solved additional expanding foam solution problem effectively, makes it industrial practicality arranged.But this device is under the air-flow effect foam to take place; vaporific being difficult at grid gap formation liquid film; usually can wear net and mistake; therefore; form in order to help liquid film; it is big that the expanding foam solution consumption is wanted, and the grid gap is little, and this not only can too much consume expanding foam solution; and the bubble diameter that generates also is restricted; in fact, what this device produced is the foams that the numerous air-bubble adhesion forms, rather than the bubble individuality that disperses; and the foaming part is placed apart with the expanding foam solution case; it is all not too convenient to operate and carry, and therefore, the use of this device is restricted widely.

The purpose of this utility model provides a kind of to the public can recur bubble, and foam device is whole with the container of dress liquid, carries with easy to operate, can use multiple liquid charging stock, and a kind of bubble generator that is widely used on producing.

The utility model is realized by following technological approaches.Utilize in the liquid container, under the effect of externally air inlet, the outer surface pressure of liquid level upward pressure and container is different, be that the liquid level upward pressure is greater than the outer surface pressure (normal atmosphere (An)) of container, liquid is just outwards run out of liquid from the airtight container gap, liquid is under the air-flow effect, form the principle of minute bubbles in the exit, through meticulous calculation Design, the container of dress liquid is made with scientific and reasonable the connecting of the tracheae that has vapour lock (assembling) and also can together, vapour lock is meant the mechanism or the element that can hinder gas flow, generally all has the narrow geometric properties of section, and is for example cone-shaped.
