Summary of the invention
The technical problem to be solved in the present invention is just: the technical problem existed for prior art, the invention provides the foam maker that the foaming of a kind of simple and compact for structure, with low cost, gas-liquid mixed, foaming effect are good, can improve foam remineralization efficacy.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of foam maker, comprise liquid spray nozzle assembly and gas nozzle assembly, described liquid spray nozzle assembly comprises feed tube and is positioned at the fluid injector of feed tube afterbody, and described gas nozzle assembly comprises air inlet pipe and gas nozzle, and described feed tube is that coaxial is sheathed in air inlet pipe.
As a further improvement on the present invention:
Described air inlet pipe is sheathed in cylinder sleeve, described cylinder sleeve and gas nozzle are connected to form cavity, described cylinder sleeve is separated into two inner chambers by the piston ring be connected on air inlet pipe outer wall, described air inlet pipe and the inner space near gas nozzle side, be provided with Compress Spring between described piston ring and the inboard wall of cylinder liner away from gas nozzle one end.
Fluid injector on described feed tube is in the piston-like coordinated with gas nozzle.
Described air inlet pipe is all overlapped connected components with coaxial double-pipe with the entrance point of feed tube and is connected.
Compared with prior art, the invention has the advantages that:
1, foam maker of the present invention, liquid spray nozzle assembly and gas nozzle assembly are integrated in one piece, and employing cooperatively interacts, non-interference Nested design, thus the liquid containing all kind medicaments and gases at high pressure can be mixed together ejection, be filled with after gas-liquid mixed in medium, play best bubble effect, and then reach preferably foam remineralization efficacy.
2, foam maker of the present invention, air inlet pipe, feed tube and cylinder sleeve are designed to interlock form, automatic unlatching, closedown can be realized, the negative-pressure ward liquid that not only can be sprayed by gas, play best effect, all right self-closed liquid nozzle, prevents external agency from blowing back in spray gun, avoids spray gun block and be corroded.

Detailed description of the invention
Below with reference to Figure of description and specific embodiment, the present invention is described in further details.
As shown in Figure 1, Figure 2 and Figure 3, foam maker of the present invention, comprise liquid spray nozzle assembly and gas nozzle assembly, liquid spray nozzle assembly comprises feed tube 1 and is positioned at the fluid injector 2 of feed tube 1 afterbody, gas nozzle assembly comprises air inlet pipe 3 and gas nozzle 7, and feed tube 1 is sheathed in air inlet pipe 3 in coaxial.Emission direction along liquid, gas is front, and fluid injector 2 is positioned at the rear end of gas nozzle 7.Liquid spray nozzle assembly and gas nozzle assembly are integrated in one piece by the present invention, and employing cooperatively interacts, non-interference Nested design, thus the liquid containing all kind medicaments and gases at high pressure can be mixed together ejection, be filled with after gas-liquid mixed in medium, play best bubble effect, and then reach preferably foam remineralization efficacy.
In the present embodiment, air inlet pipe 3 is sheathed in cylinder sleeve 4, and cylinder sleeve 4 and gas nozzle 7 are connected to form cavity, form gun barrel 6 between cylinder sleeve 4 and gas nozzle 7.Cylinder sleeve 4 is separated into two inner chambers by the piston ring 9 be connected on air inlet pipe 3 outer wall, and air inlet pipe 3 and the inner space near gas nozzle 7 side, be provided with Compress Spring 5 between piston ring 9 and cylinder sleeve 4 inwall away from gas nozzle 7 one end.Fluid injector 2 on feed tube 1 is in the piston-like coordinated with gas nozzle 7, and fluid injector 2 can adopt flexible material to make, and is the seal form of nested shape with gas nozzle 7.Feed tube 1 can adopt hollow valve rod.
In the present embodiment, air inlet pipe 3 is all overlapped connected components 8 with coaxial double-pipe with the entrance point of feed tube 1 and is connected, and can complete connection easily and quickly.
Operation principle:
(1) spray gun duty, gas-liquid mixed is sprayed;
See Fig. 3, gas and liquid are by air inlet pipe 3 and the hollow valve rod of feed tube 1() coaxial double-pipe cover connected components 8 of being provided with of end sends into.Gas enters the inner chamber near gas nozzle 7 side, when cylinder sleeve 4 internal gas pressure reach pressure is set time, piston ring 9 will be moved to the left and compress Compress Spring 5, and then drive air inlet pipe 3 and feed tube 1 to be synchronously moved to the left, now the fluid injector 2 of feed tube 1 upper piston shape leaves gas nozzle 7, and the nozzle of spray gun is in open mode.Now, gas sprays through air inlet pipe 3, gun barrel 6 to gas nozzle 7, and liquid sprays through feed tube 1 to fluid injector 2.Due to fluid injector 2, in fact distance gas nozzle 7 is not far, and the high velocity air around it makes fluid injector 2 place produce negative pressure, the automatic sucking-off of liquid.Medium is sprayed into after gas-liquid mixed.Gas, medium, foaming agent can mix the fine firm bubble of generation well, greatly improve flotation effect.
(2) spray gun closed condition, gas-liquid injection stops;
After outside air feed stops, in spray gun, gas pressure is down to setting value, Compress Spring 5 can progressively discharge, promote piston ring 9, and then drive air inlet pipe 3 and feed tube 1 synchronously to move right, fluid injector 2 in software piston-like on feed tube 1 can withstand gas nozzle 7, simultaneously fluid injector 2 is squeezed power, and fluid injector 2 is closed.After spray gun quits work, external agency can not blow back in spray gun, avoids spray gun block and be corroded.
Below be only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, should be considered as protection scope of the present invention.
