Description

A kind of water paint spraying shower nozzle

Technical field

The utility model relates to a kind of shower nozzle, particularly a kind of water paint spraying shower nozzle.

Background technology

At present; shower nozzle of the prior art; the injection flow of some is inhomogeneous; some needs bigger but not the becoming greatly of spraying swath face; the design of some shower nozzle is undesirable; the spray nozzle clogging phenomenon appears through regular meeting; the patent No. is as has been publicly: a kind of mister head of ZL98220607.0; this shower nozzle also has a V-shaped groove; but this V-shaped groove has only a slight nozzle location just to have; not the opening V-shaped groove, therefore can not form a big spraying swath face, in addition owing to there is not current-limiting apparatus; realize straight spray; the unsettled flowing velocity of some of fluid directly has influence on the effect and the breadth of shower nozzle ejection like this, might make the big a little while a little while little phenomenon of the fluid that gushes out, and these defectives have all had influence on user's service efficiency.

The utility model content

Little for solving water paint spraying shower nozzle injection breadth of the prior art, the easy blocking problem of shower nozzle provides a kind of injection breadth big, and shower nozzle is not allowed susceptible to plugging water paint spraying shower nozzle.

For addressing the above problem, water paint spraying shower nozzle of the present utility model comprises a nozzle and a sprayer body, its special card is: a V-notch elongated slot is arranged at the nozzle place, one oval outlet is arranged at V-notch elongated slot middle part, with V-notch elongated slot intersection be the hemisphere cavum of a spheroid, the spheroid hemisphere cavum communicates with the nozzle endoporus, and a spoiler also is set in sprayer body.

Water paint of the present utility model spraying shower nozzle also comprises and has a following technical characterictic:

A through hole is arranged on the spoiler;

Through-hole diameter on the spoiler is identical with the nozzle diameter of bore.

Owing to increased the V-notch elongated slot, make the injection breadth reach a fan-shaped spray at whole jet face, increased jet face.

Water paint spraying shower nozzle of the present utility model is provided with the hemisphere cavum of spheroid at the nozzle place, be not direct ejection when making fluid flow to the nozzle place, but flows to the V-notch ejection under the extruding of spheroid hemisphere cavum, has so just prevented that fluid from sticking on the nozzle.

Water paint spraying shower nozzle of the present utility model is provided with spoiler in sprinkler body, spoiler has a through hole identical with the nozzle diameter of bore, like this when fluid flows to through hole, through hole plays the effect of a buffering, make fluid more stable when shower nozzle is penetrated, guarantee the uniformity of fluid, also avoided some impurity and so on to block nozzle at the shower nozzle place, replacing and cleaning spoiler are simple more than nozzle clearing, have so just guaranteed the normal use of shower nozzle.

The specific embodiment

As shown in Figure 1, water paint spraying shower nozzle of the present utility model comprises a sprayer body 3, a nozzle 2 and a spoiler 8.

To shown in Figure 4, sprayer body 3 has on one internal cavity 4 and internal cavity 5 once as Fig. 2, and last internal cavity 4 is littler than following internal cavity 5.Nozzle 2 is arranged on the upper end of sprayer body 3, upper end at nozzle 2 has a V-notch elongated slot 0, V-notch elongated slot 0 passes across the upper surface of sprayer body 3, the otch angle of V-notch elongated slot 0 is about 40 °, at V-notch elongated slot 0 middle position one oval outlet 11 is arranged, its shape as shown in Figure 4; What intersect with V-notch elongated slot 0 is the hemisphere cavum 1 of spheroid, with spheroid hemisphere cavum 1 tangent be nozzle endoporus 12, nozzle endoporus 12 led directly to sprayer body 3 ends.When fluid when nozzle endoporus 12 flows to, because two outstanding spheroid hemisphere cavums 1 that are higher than oval outlet 11 are arranged, so fluid is introduced into spheroid hemisphere cavum 1, interior circle by spheroid hemisphere cavum 1 pushes out then, flow into oval outlet 11 then,, fluid can directly not sprayed from shower nozzle from ellipse outlet 11 ejections, but come out from 1 extruding of spheroid hemisphere cavum, form the fan-shaped spray of imitative V-notch elongated slot direction.

As shown in Figure 1, spoiler 8 has an inner chamber 6 and a lower inner cavity 10 on one, one through hole 7 is arranged between last inner chamber 6 and lower inner cavity 10, the diameter of through hole 7 is identical with the diameter of nozzle endoporus 12, one outstanding edge 9 of spoiler 8 is pressed on the sprayer body 3, and the center of the center of through hole 7 and nozzle endoporus 12 is on same the center line like this.When shower nozzle is worked, fluid at first passes through through hole 7, flow on the nozzle 2 from through hole 7 again, like this, when a particle is arranged in the fluid than the big impurity of through hole 7 diameters, at first be blocked in through hole 7 places, thereby prevented that granule foreign from blocking nozzle 2, because change and cleaning spoiler 8 simpler and many easily than nozzle clearing 2, only need spoiler 8 pulled down and get final product; Through hole 7 has been arranged on the other hand, make fluid contact with through hole 7 earlier,, thereby make fluid be subjected to certain buffering at through hole 7 places because through hole 7 diameters are identical with the diameter of nozzle endoporus 12, fluid is more stable when flowing to nozzle 2, the uniformity when having guaranteed the fluid ejection.

Water paint spraying shower nozzle embodiment 1 of the present utility model: as shown in Figure 5, according to experiment test, when the otch angle of V-notch elongated slot 0 is 40 °～50 °, when the spheroid hemisphere cavum is SR0.5, when transportation work pressure is lower than 1.8bar, the spray that from spray orifice, sprays reduce with pressure and spreading of spray reduce until becoming a line ejection.

Water paint spraying shower nozzle embodiment 2 of the present utility model: as shown in Figure 6 and Figure 7, according to experiment test, when the otch angle of V-notch elongated slot 0 is 40 °～50 °, when the spheroid hemisphere cavum is SR0.5, during less than 3.5bar, the spray that sprays from spray orifice is a sector spray to transportation work pressure, remains on the 25cm height and sprays greater than 1.8bar, there is the spraying swath area operation effectiveness of spraying swath face 20～25cm in the front, and A is to being seen as a sheet type spray from the side.

Water paint spraying shower nozzle embodiment 3 of the present utility model: as Fig. 8 and shown in Figure 9, according to experiment test, when the otch angle of V-notch elongated slot 0 is 40 °～50 °, when the spheroid hemisphere cavum is SR0.5, transportation work pressure is greater than 3.5bar during less than 5bar, the fan-shaped spray of ejection is formed with stronger impulsion power, has the mist of secondary-atomizing to exist under the proximity condition.

, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiment of the present utility model describing the present invention property and nonrestrictive description.
