Described first air cavity is communicated with extraneous source of the gas by the air inlet be located on described housing.
The front end of described second air cavity is in communication with the outside by the air nozzle be located on described housing, and its rear end is communicated with the first air cavity by the groove be located on described tapered sleeve outer wall.
Described groove is the skewed slot tilted to same direction.
Described air nozzle is established around described water spout.
The intensity of described front spring is greater than the intensity of described rear spring.
The beneficial effects of the utility model are: the utility model by a fine needle under pressure differential effect automatically from inside by its water spout shutoff or unlatching, thus completely avoid extraneous dust and enter and cause water spout Abnormal Blocking, to keep water channel unimpeded.Separately, the utility model inside can form High Rotation Speed air-flow, clashes into into fine particle by the water sprayed by water spout, contributes to increasing water smoke to the active area of ambient dust, improves anti-dust effect.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
With reference to Fig. 1-7:
A kind of automatically cleaning sprinkler head, comprises housing 1 and bonnet 2.
Housing 1 inner chamber is provided with water pipe 3 and a tapered sleeve 4, and the front portion of water pipe 3 is plugged in the mantle cavity of tapered sleeve 4, and seals by the mantle cavity peristoma of a sealing ring 5 pairs of tapered sleeves 4;
The tube chamber front end of water pipe 3 is communicated with the mantle cavity of tapered sleeve 4 by the multiple apopore 3a be located on its tube wall, and the rear end of water pipe 3, through bonnet 2, is connected with external water source;
The conehead place of tapered sleeve 4 is provided with a water spout 4a, and water spout 4a is plugged in the through hole 1a set by housing 1 front end, and water spout 4a is by fine needle 3b shutoff or the unlatching by seesawing being located at water pipe 3 front end;
The outer ring of water pipe 3 is fixedly connected with a piston 6, and piston 6 is communicated with extraneous source of the gas by the air inlet 1b be located on housing 1 with first air cavity 7, first air cavity 7 that is partitioned into of tapered sleeve 4;
The second air cavity 8 is formed between tapered sleeve 4 and housing 1 inwall, the front end of the second air cavity 8 is in communication with the outside by an air nozzle 1c, air nozzle 1c is located on housing 1 around encirclement water spout 4a, and the rear end of the second air cavity 8 is then communicated with the first air cavity 7 by the skewed slot 4b tilted to the same side be located on tapered sleeve 4 outer wall;
The water pipe 3 of the forward and backward side of piston 6 is socketed with respectively front spring 9 and rear spring 10, front spring 9 is located between tapered sleeve 4 and piston 6, and rear spring 9 is located between piston 6 and bonnet 2, and the intensity of front spring 9 is greater than the intensity of rear spring 10.
Operation principle of the present utility model is: as shown in Figure 7, and when shower nozzle enters duty, extraneous water enters in the mantle cavity of tapered sleeve 4 by the tube chamber of water pipe 3 and osculum 3a, and air is continued to enter in the first air cavity 7 by air inlet 1b by external air source.Because now the water spout 4a of tapered sleeve 5 blocks by fine needle 3b completely, water temporarily cannot be discharged; Along with the air pressure in the first air cavity 7 continues to rise, when in it, pressure is greater than the tension force of rear spring 10 with the thrust sum of front spring 9 pairs of pistons 6, piston 6 retreats, piston 6 drives water pipe 3 to retreat, the fine needle 3b of water pipe 3 front end also retreats thereupon, until fine needle 3b is separated completely with water spout 4a, water spout 4a opens, and the water put aside in tapered sleeve 4 mantle cavity outwardly sprays from water spout 4a.Meanwhile, air in first air cavity 7 enters in the second air cavity 8 by the skewed slot 4b on tapered sleeve 4 outer wall, High Rotation Speed air-flow is formed in the second air cavity 8, High Rotation Speed air-flow is sprayed by the air nozzle 1c established around water spout 4a, the mutual high-speed impact of the aqueous phase sprayed with water spout 4a, water is diffused into surrounding after being broken into tiny particle.
As shown in Figure 6, when shower nozzle end-of-job, extraneous water and air all stops injecting.Air pressure in first air cavity 7 declines, when in it, pressure is less than the tension force of rear spring 10 with the thrust sum of front spring 9 pairs of pistons 6, piston 6 moves ahead, and water pipe 3 and fine needle 3b also and then advance, until water spout 4a blocks from inside by fine needle 3b, external dust cannot enter water spout 4a and shower nozzle is inner.
