Detailed description of the invention
Applicant will describe in detail the specific embodiment of the present invention below by reference to the accompanying drawings; but applicant is not the restriction to technical scheme to the description of embodiment, any changing in the form rather than substance according to the present invention's design all should be considered as protection scope of the present invention.
Refer to Fig. 1, the present invention relates to a kind of multifunctional spray tank, comprise inside be formed liquid storage cylinder 11 tank body 1, be located at the buffer cover 2 in liquid storage cylinder 11 and be positioned at above buffer cover 2 and the cover 3 be arranged on tank body 1.Described tank body 1 is provided with high pressure nozzle 12 in the bottom of liquid storage cylinder 11, the high pressure nozzle 12 narrow contracting and form a high velocity air spout 121 in end gradually towards upper one end in a state of use, high pressure nozzle 12 in a state of use towards under one end extend to outside liquid storage cylinder 11, for being communicated with external air source.Described buffer cover 2 comprise top have opening, bottom hollow out atomizing cup 21 and be arranged on immediately below atomizing cup 21 with the cone cover 22 of described high pressure nozzle 12 adaptation.Described atomizing cup 21 is formed with striker 211, on the medial wall of opening part, is formed with a limited post 212 along short transverse in die cavity.Described atomizing cup 21 outwards turns down on the upper edge of opening part and is formed with dividing plate 213, and described dividing plate 213 to be positioned at immediately below vestibule 32 of giving vent to anger and to fit with the chamber wall of described tank body 1.Described cone cover 22 is set in outside high pressure nozzle 12, and the space between the outer wall of high pressure nozzle 12 and the inwall of cone cover 22 is configured to air-flow rotating channel 5.The cone point upward of cone cover 22 extends to the cavity bottom of atomizing cup 21, and makes cone point be positioned at immediately below striker 211, and cone cover 22 offers liquid injection port 221 at cone tip part.Described cover 3 forms medicine liquid channel 31 in the central authorities of short transverse, cover 3 is configured with give vent to anger vestibule 32 and the dosing vestibule 33 be communicated with medicine liquid channel 31 be communicated with inner die cavity at top, base plate 331 bottom described dosing vestibule 33 tilts towards medicine liquid channel 31, is conducive to liquid medicine flow.The medicine liquid channel 31 of cover 3 forms one for forming with limited post 212 stopper slot 311 that inserting installs on the bottom wall body of short transverse, and make medicine liquid channel 31 be connected with the die cavity of atomizing cup 21 thus and communicate, the die cavity of atomizing cup 21 communicates with liquid storage cylinder 11.Described cover 3 is formed at the bottom margin of short transverse and agrees with groove 34 towards tank body 1 opening, described tank body 1 is arranged at intervals with and agrees with convex tooth 13 on the lateral wall of tank mouth, described agree with convex tooth 13 and agree with groove 34 clamping with described and realize being fixedly connected with of tank body 1 and cover 3, the vestibule 32 of giving vent to anger be positioned on cover 3 is communicated with the liquid storage cylinder 11 of tank body 1 via the inner die cavity of cover 3.Described multifunctional spray tank also comprises aerosol amount governor motion 4, and described aerosol amount governor motion 4 comprises adjustable cap 41, control valve 42 and lasso 43.Described adjustable cap 41 is embedded in dosing vestibule 33, adjusting rod through hole 411 is offered in the middle of the bottom of adjustable cap 41 short transverse, louver(-vre) 412 is offered between the outside surrounding of described adjusting rod through hole 411 and the wall body of adjustable cap 41, the quantity of louver(-vre) 412 is more than one, in the present embodiment, the quantity of described louver(-vre) 412 is four, arranges in uniform intervals.The upper edge of adjustable cap 41 short transverse outwards turns down and is formed with bead 413, and described bead 413 forms with the outer edge at dosing vestibule 33 top and is sealed and matched, and bead 413 is extended with a lug 4131 at outer edge.Described control valve 42 is positioned at the below of adjustable cap 41, control valve 42 has adjusting rod 421 towards the axially middle extended of adjustable cap 41 side in a state of use, described adjusting rod 421 forms a defining flange 4211 in the middle and lower part of short transverse, the upper end of adjusting rod 421 through after adjusting rod through hole 411 on lean out outside adjustable cap 41, make described control valve 42 and described adjustable cap 41 structure for being fixedly connected with by defining flange 4211 and coordinating of adjusting rod through hole 411.The sidewall that described lasso 43 is arranged on adjustable cap 41 forms the figure of eight with adjustable cap 41, gives vent to anger on the outer wall of vestibule 32 described in this lasso 43 is set in.When needs dosing, lug 4131 is utilized to be extracted from dosing vestibule 33 together with control valve 42 by adjustable cap 41, and swivel ferrule 43, make adjustable cap 41 and control valve 42 be positioned at the side of dosing vestibule 33, reset again after dosing completes.
Refer to Fig. 2 and Fig. 3, and composition graphs 1, describe operation principle of the present invention: in use, need first to be extracted from dosing vestibule 33 by aerosol amount governor motion 4, medicinal liquid is from dosing vestibule 33 through medicine liquid channel 31, enter liquid storage cylinder 11 through the die cavity of atomizing cup 21 again for aerosol can; High pressure nozzle 12 connects an external air source, for providing pressure-air; The accent of vestibule 32 of giving vent to anger need connect a nozzle or face shield, and patient carries out air-breathing via nozzle or face shield.Open source of the gas, external high pressure air enters atomizing cup 21 die cavity through the high velocity air spout 121 of high pressure nozzle 12 and the liquid injection port 221 of cone cover 22 and impacts striker 211, according to venturi principle, produces negative pressure in local.Air-flow after shock enters bottom the medicinal liquid of liquid storage cylinder 11 through air-flow rotating channel 5, produces pressure reduction with the air-flow outside medicinal liquid, under the effect of this pressure reduction, form aerosol, derives from the accent of vestibule 32 of giving vent to anger.When patient presses the adjusting rod 421 of aerosol amount governor motion 4, adjustable cap 41 is separated with control valve 42, produces gap between the two, extraneous air enters in aerosol can, because negative pressure is pooled to striker 211 place, accelerates medical liquid atomizing, the aerosol amount of aerosol can increases, and patient respiratory is more smooth and easy.Press down amplitude by what change adjusting rod 421, adjustable natural air sucks flow in aerosol can to obtain different atomization speeds, thus can tackle the different dispensing situation of all ages time patient.Inhale in medicine process patient, time have overturn aerosol can situation occur, in the present embodiment, because dividing plate 213 has been installed in the position of vestibule 32 of giving vent to anger in liquid storage cylinder 11 correspondence, thus can effectively prevent the medicinal liquid do not used from overflowing from vestibule 32 of giving vent to anger, avoid medicament to waste.
