The specific embodiment
Referring to car light washer nozzle shown in Figure 3, it is made up of following three parts: nozzle body 1, centrifugal guide card 2, centrifugal top guide 3.
Referring to Fig. 3, Fig. 1, in the direction that flows to along cleaning fluid, the downstream of described nozzle body 1 comprises eddy flow groove 12, and the bottom of eddy flow groove 12 offers spout 13.
Referring to Fig. 3, Fig. 4, in the direction that flows to along cleaning fluid, described centrifugal guide card 2 is positioned at the upstream of eddy flow groove 12, and the inner body wall 11 of the guide card outer wall 23 of centrifugal guide card 2 and nozzle body 1 is sealed and matched; Offer the centrifugal jet orifice 22 that runs through centrifugal guide card 2 on the centrifugal guide card 2, also offer the eccentric groove 21 of strip on the surface that deviates from eddy flow groove 12 of centrifugal guide card 2, one end of described eccentric groove 21 is communicated with centrifugal jet orifice 22, and the axial line space of the bearing of trend of eccentric groove 21 and centrifugal jet orifice 22 from.Wherein centrifugal jet orifice 22 is a circular hole, and the bearing of trend of eccentric groove 21 is the tangential direction of the hole wall of centrifugal jet orifice 22; And the other end of eccentric groove 21 also is communicated with guide card outer wall 23.Described eccentric groove 21 is along the hole wall of centrifugal jet orifice 22 equally distributed four.
Referring to Fig. 3, Fig. 2, Fig. 4, described centrifugal top guide 3 comprises top guide top and the straight injection stream pipe 33 that is connected with described top guide top, and in the direction that flows to along cleaning fluid, described top guide top is positioned at the upstream of centrifugal guide card 2; The top guide outer wall 34 and the inner body wall 11 at described top guide top are sealed and matched, and the sealing of the opposite face of described top guide top and centrifugal guide card 2 is fitted, and the top guide top also offers the pod apertures 31 that is communicated with eccentric groove 21, and the number of pod apertures 31 is identical with eccentric groove 21; Straight injection stream pipe 33 passes centrifugal jet orifice 22, has the gap between straight injection stream pipe 33 and the centrifugal jet orifice 22, also has the gap between straight injection stream pipe 33 and the spout 13; Described centrifugal top guide 3 also comprises the straight injection discharge orifice 32 that runs through described top guide top and straight injection stream pipe 33.Specifically, straight injection stream pipe 33 is cylindric and axial line overlaps with the axial line of centrifugal jet orifice 22, and the external diameter of straight injection stream pipe 33 is less than the internal diameter of centrifugal jet orifice 22.Above-mentioned various being sealed and matched can compress sealing for what interference fit formed.
Referring to Fig. 4, the operation principle of said nozzle is: (A) cleaning fluid accumulates in the upstream of nozzle body 1; (B) referring to the dotted arrow among Fig. 4, part cleaning fluid flows into eccentric groove 21 (invisible among this figure) after the gap between straight injection stream pipe 33 and the centrifugal jet orifice 22 flows into eddy flow groove 12 by pod apertures 31, since the axial line of the bearing of trend of eccentric groove 21 and centrifugal jet orifice 22 from, cleaning fluid by centrifugal, and then approaches spout 13 in the mode of at a high speed rotation in eddy flow groove 12 in eccentric groove 21; (B ') referring to the solid arrow among Fig. 4, another part cleaning fluid flows into a straight end that sprays discharge orifice 32, and flow out from the other end of straight injection discharge orifice 32, and enter in the spout 13; (C) the cleaning fluid jet of above-mentioned two kinds of different flow regimes crosses, merges at spout 13, and a part is atomized ejection by the mode of centrifugal fragmentation, thereby reaches the effect of the auxiliary cleaning of big angle of flare, granule atomized drop; And a part directly is directed into outside the spout 13 in addition, thereby makes this part cleaning fluid penetrate the effect that reaches the emphasis cleaning at a high speed in the mode of little angle of flare, bulky grain atomized drop.Above-mentioned two kinds of cleaning ways organically combine, the cleaning performance of rotarytype injector and direct injection nozzle is merged, supply mutually, learn from other's strong points to offset one's weaknesses, reached and effectively to have cleaned the high-effect light-emitting zone on car light surface, can clean the effect on the auxiliary light emission surface of high-effect light-emitting zone periphery again.Adopt above-mentioned technology, can improve cleaning efficiency, the saving cleaning fluid of washer, the cleaning fluid capacity that makes vehicle to carry reduces, and meets very much low-carbon (LC), environmental protection concept that country advocates.
Though the utility model with preferred embodiment openly as above; but it is not to be used for limiting claim; any those skilled in the art are not in breaking away from spirit and scope of the present utility model; can make possible change and modification, therefore protection domain of the present utility model should be as the criterion with the scope that the utility model claim is defined.
