Described filter screen is fixed on the Flow-rate adjustment seat.

When current advanced above-mentioned rotary nozzle, net filtration after filtration earlier regulated through the Flow-rate adjustment seat then that to enter the water flowing plug behind the flow inner and from its top ejection, and current enter in the radial tank of rotary body after the ejection of water flowing plug.This moment, current were split into the slowly rotation under the double action of the promotion of current and damping structure of strip and rotary body.

The annular aperture of above-mentioned water flowing plug can be 90 degree, 180 degree, 270 degree, four kinds of different distributions of 360 degree, so rotary nozzle also can spray the current of 90 degree, 180 degree, 270 degree, four kinds of different distributions angles of 360 degree.

Compared with prior art, advantage of the present utility model is:

1, rotary body Rotating with Uniform and spraying evenly under the effect of current and damping mechanism.

2, the different water flowing plugs of assembling can be realized 90 degree, 180 degree, 270 degree, four kinds of different spray fields of 360 degree.

Thereby 3,, can realize the adjusting of spray radius and flow by rotating the water yield in the regulating shaft adjusting Connection Block.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, shown in Figure 3, rotary nozzle 1 comprises swivel head 10, water-through base 20 and filter screen 30 3 parts.

The structure of swivel head 10 sees Fig. 4 for details, it comprises rotary body 11, when ring 12, damping axle 14, damping oil 15, regulating shaft 17, rotary body 11 is circular, its back side has the groove 1101 of radial slightly radian, see Fig. 5, damping axle 14 is assembled together by damping oil 15 and regulating shaft 17, and damping axle 14 is fixed on the center of rotary body 11 by baffle ring 12, and the sealing ring 13 and the sealing ring 16 that prevent that damping oil 15 from revealing are installed in damping axle 14 top and bottom.

Damping oil 15 is between damping axle 14 and rotary body 11, and Rotating with Uniform body 11 rotary speed excursions under different hydraulic pressure can be played in the gap of its formation.

When the current that gushed out by water-through base 20 are flowed through rotary body 11 backside trench 1101 fast, because the effect of current, rotary body 11 will rotate around regulating shaft 17, and current are also because the effect of groove 1101 is broken down into strip from 11 one-tenth radial dishing out of rotary body.

Damping axle 14 is installed in the upper end of regulating shaft 17, plays the effect of supporting rotator 11.

There is in-line translot 1401 on above-mentioned damping axle 14 its tops, see Fig. 6, peak at the instrument that is similar to screwdriver and can drive regulating shaft 17 rotations that are fixed on damping axle 14 lower ends on the translot 1401.Rotation by means of regulating shaft 17 drives the water spray radius adjusting within the specific limits that 23 rotations of Flow-rate adjustment seat can realize regulating rotary nozzle 1 flow and shower nozzle again.

Water-through base 20 comprises Connection Block 21, water flowing plug 22, Flow-rate adjustment seat 23.

Connection Block 21 supporting rotators 11, port has oblique angle 2101 above it, collides with rotary body 11 preventing, sees Fig. 7 for details, and it wears the through hole that holds water flowing plug 22 down.

Water flowing plug 22 is set in the centre of Connection Block 21, and the cylindrical hole 2103 of Connection Block 21 and cylindrical hole 2104 cooperate with the face of cylinder 2202 of water flowing plug 22 and the face of cylinder 2203 respectively.Form the slit of annular between the circular hole that has the oblique angle 2102 of Connection Block 21 and the face of cylinder 2204 of water flowing plug 22, from then on the current that have hydraulic pressure are ejected on the rotary body with cylindrical in the slit.

Water flowing plug 22 has different kinds, and shown in Figure 10 is 360 degree water flowing plugs 22, has the looping pit 2205 of 4 90 degree on it, and looping pit 2205 is divided into four not interconnective parts with the water flowing plug.

The bottom of water flowing plug has the scalloped recess 2101 of two symmetries, see Fig. 8, scalloped recess 2101 cooperates the formation aperture area to regulate with the annular opening 2301 of Flow-rate adjustment seat 23 window can drive the function that 23 rotations of Flow-rate adjustment seat are regulated with realization Flow-rate adjustment and radius when regulating when damping axle 14 drives regulating shafts 17 rotations.

The water flowing plug also has 270 degree water flowing plugs, has the boss 2206 of 90 degree and the looping pit of 3 90 degree above it, sees Figure 11.The boss 2207 of 180 degree and the looping pit of 2 90 degree are worn in 180 degree water flowings beyond the Great Wall, see Figure 12.90 degree water flowing plugs have the boss of 270 degree and the looping pit of 1 90 degree, see Figure 13.

The structure of Flow-rate adjustment seat 23 is seen Figure 14 and Figure 15.The annular opening 2301 that two symmetrical distributions are arranged above the Flow-rate adjustment seat cooperates the formation flow control device in order to the scalloped recess 2101 with the water flowing plug, and regulating shaft 17 and spacing is inserted at its center.

Filter screen 30 is connected on the Flow-rate adjustment seat 23, plays the effect that impurity prevents to stop up rotary nozzle in the filtered water.
