The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Anticipate as shown in the figure, a kind of emulsion vacuum pump, it includes the head cap 1 of band nozzle, bottle 4, great circle 3 major parts such as grade, great circle 3 is connected bottle 4 bodies by helicitic texture or snap ring draw-in groove structure, and head cap 1 can telescopically be installed in the middle of the great circle 3, nozzle component on these and the traditional atomizing cone is similar, here no longer carefully state, the crucial part of its invention is the plastic cement pump 2 that useful rubber in addition or silica gel material are made, see Fig. 6-7, plastic cement pump 2 is sleeve-shaped substantially, and the top is the elastic surface 21 of ring-type, and the centre has annular groove 22, groove 22 width are little by little to diminish from top to down, the bottom on the step surface of plastic cement pump 2 the insides, molds clasp 24 and annular spacing groove 25 for the bulge loop 23 on band inclined-plane respectively, like this, plastic cement pump 2 is nested with on the hydrojet post 31 at great circle center, has formed liquid cavity 7 between plastic cement pump 2 and the head cap 1, form first one-way valve structures between plastic cement pump 2 and 31 outlets of hydrojet post.First one-way valve structures is that the elastic surface 21 of plastic cement pump 2 end faces posts on hydrojet post 31 tops, hydrojet post 31 top peripheries mold three hydrojet column outlets 32, be circularly and evenly distributed, near near the hydrojet cornice outlet circular groove 33 and bulge loop 34 are arranged, the clasp 24 of plastic cement pump 2 inboards is buckled on the circular groove 33, bulge loop 34 embeds annular spacing groove 25, make and form first one-way valve structures between plastic cement pump 2 and the hydrojet column outlet 32, pressure in bottle is big, and the pressure of 7 li of liquid cavity is little, make the liquid in the hydrojet post 31 pass through outlet 32, back down the elastic surface 21 of plastic cement pump end face, be punched into 7 li of liquid cavity, and liquid can't backflow in the bottle in the liquid cavity.Other has head cap 1, sees Fig. 4-5, and head cap 1 presents the lid shape of being with nozzle, and still, it has outer ring periphery 11 and lining circular periphery 12, and, open pore 13 is arranged on the circular periphery of lining.And, strip shape open pore 13 has two, present circumference and be symmetrical arranged distribution, in circular periphery 12 be inserted in the annular groove 22 in the plastic cement pump, make to form second one-way valve structures in annular groove elasticity wall 26 on the plastic cement pump circumferential location and the head cap between the open pore 13 on the circular periphery, circular periphery 12 outsides are communicated with nozzle in the head cap.Second one-way valve structures is that circular periphery 12 embeds in the annular groove 22 on the plastic cement pump circumferential location in the head cap, and mold up and down the strip shape open pore 13 that extends in the head cap on the circular periphery 12, cooperates and contact seal with the elasticity wall 26 in the annular groove outside, make in annular groove elasticity wall 26 on the plastic cement pump circumferential location and the head cap formation second one-way valve structures between the open pore 13 on the circular periphery.Contact seal is carried out in underrun plastic cement pump bottom between head cap outer ring periphery 11 and the lining circular periphery 12, and it is realized by plastic cement pump bottom and their interference fit.The outer ring periphery 11 inboard faces of head cap are distributed with three projectioies 14 equably, support the bottom surface of plastic cement pump 2.Piston body 5 is installed in the bottle 4, sees Figure 12-13, piston body 5 adopts arc valve 51, is convenient to the bottle inwall and carries out slipper seal, and the centre of piston body 5 is connected with a plurality of step cutting patterns 52, can improve the intensity of piston body greatly.See Fig. 8-11, bottle 4 is divided into bottle body 41 and bottle bottom 42, and bottle body 41 lower circumference are distributed with snap ring 43, and bottle bottom 42 circle distribution have draw-in groove 44, and bottle body 41 and bottle bottom 42 are coupled together by draw-in groove and snap ring fit structure.And bottle body 41 bottoms are symmetrically distributed with one section latch 45, with bottle bottom 42 inboard circumference well-distributed latch groove 46 engagement fit, prevent the rotation between them and deviate from, and have improved the bonded assembly steadiness.Just open on bottle bottom 42 with the aperture 8 that the external world is ventilative.Great circle 3 structures are seen Figure 14-15, and it gets up by the snap ring clamping on draw-in groove and the bottle 4, in order to improve sealing property, are lined with pad between great circle 3 and bottle 4 oral areas.In the middle of the great circle 3 is exactly hydrojet post 31, molds snapping portion 35 on great circle 3 circumference, carries out spacing the cooperation with the bulge loop 15 of head cap 1 bottom, prevents that head cap 1 from use ejecting disengaging.Make three arc shrinkage pools 36 on great circle 3 outer circumference surfaces, cooperate, cover cap 6 can be connected on the great circle 3, play a protective role with projection on the transparent cover cap 6 inboard faces.
Its principle of work is such, when using emulsion vacuum pump, as long as push head cap 1 with hand, make head cap 2 overcome the elasticity tension of plastic cement pump 2, move downward, liquid cavity 7 between head cap 1 and the plastic cement pump 2 is diminished, the pressure of liquid cavity 7 just increases, simultaneously, plastic cement pump 2 is subjected to downward pressure, and certain elastic deformation takes place, and the elasticity wall 26 of its annular groove outside is moved down in right amount and is out of shape, the open pore 13 of the strip in making on the head cap on the circular periphery trend that comes out, simultaneously, in conjunction with the attenuation of elasticity wall 26, make the liquid in the liquid cavity 7 wash elasticity wall 26 open, make second check valve be in open mode, ejection liquid is by the nozzle ejection of head cap 1; And during openhanded opening; head cap 1 resets under the resilient force of plastic cement pump 2; upward movement; liquid cavity 7 between head cap 1 and the plastic cement pump 2 is increased; pressure decay in the liquid cavity 7; contrary principles; second check valve of this moment is to be in closed condition; and the bottle cavity 7 in the hydrojet post, owing to the barometric pressure of the following segment space of piston body with the external world is communicated with, by atmospheric pressure; make piston body 5 upward movements; protection is consistent with extraneous pressure, in case the pressure of the liquid cavity 7 above the plastic cement pump 2 is less than the pressure of hydrojet post 31 outlets; make following pressure greater than top pressure; make the liquid of hydrojet column outlet 32 be easy to back down plastic cement pump elastic surface 21, make first check valve be in open mode, the liquid supplementary sum in the bottle 4 is drawn in the top liquid cavity 7; for ejection is once got ready; like this, circulation just makes emulsion vacuum pump constantly spray liquid successively.
