Advantageous effect
Compared with prior art, it is the advantages of multipurpose of the invention sprinkling conduit：
1st, since the gap width of the second spray orifice is more than the aperture of the first spray orifice, the liquid between inner tube and shell
Handling capacity is better than the handling capacity of liquid in inner tube.When needing the diluter liquid of spray concentration, with syringe by liquid
Inner tube is pressed into from the first liquid injection port, liquid is sprayed from the first spray orifice on nozzle；When needing to spray emulsion shape liquid, with injection
Device is by liquid from the cavity between the second liquid injection port press-in inner tube and shell, and liquid is sprayed from the second spray orifice, due to the second spray orifice
Annularly, liquid when coming out in spurting, out after pool the emulsion of drops again, pass through when squeezing out emulsion shape liquid
Property it is more preferable, and the diluter liquid of concentration can be used for and be used in the higher liquid of viscosityes such as emulsion shape, the scope of application
Extensively, without developing two kinds of different spray lines of specification, development cost is reduced；
2nd, the quantity of the first spray orifice is evenly distributed with for multiple and around nozzle side walls, diffusion type in a ring during medicine liquid spray, sprinkling
It is more evenly distributed；It causes to stop when spraying the first spray orifice in order to avoid outer casing inner wall, nozzle can be mobile with inner tube and from shell
One end is stretched out.When needing the diluter liquid of spray concentration, nozzle is made to be stretched out from shell one end, when needing to spray emulsion shape liquid
When, make nozzle locking shell one end and form cyclic annular second spray orifice, it is easy to operate；
3rd, metal tube is used to reduce the total length of inner tube, even if inner tube is plastic flexible pipe, metal tube can also ensure as far as possible
Inner tube will not excessive deformation in moving process；
4th, position-limit mechanism can prevent inner tube and the range for moving out setting of shell, avoid the leakproofness of the two junction
It can be destroyed, ensure the normal use of sprinkling conduit；
5th, inner tube and shell are transparent configuration, and personnel is facilitated to see fluid flow inside situation, are conducive to spray line
Working condition it is normal whether judged；
6th, by the way that the direction of the second spray orifice and the angular range of the extending direction of inner tube is allowed to be 5-20 °, so as to increase the
The maximum area in two spray orifice exits reduces resistance when emulsion shape liquid sprays；
7th, it is nested together by plastic inner pipe and outer tube, has better supporting role in double-skin duct hardness, be not required to
It to be supported by the external force of wire guide.
By following description and with reference to attached drawing, the present invention will become more fully apparent, these attached drawings are used to explain the present invention
Embodiment.
