Further, described sprinkler body arranges at least one air inlet, air inlet with for L-type structure, air inlet and gasLiquid hybrid chamber connects.
Further, when described sprinkler body is provided with more than 2 air inlets, air inlet includes more than 2 pore branchesCollecting main stem with air-flow, it is vertical that described pore branch collects main stem with described air-flow, and pore branch is vertical with inlet opening,Air-flow collects main stem and connects with gas-liquid mixed chamber.
Further, described air inlet being additionally provided with the first air-flow accelerated passage, the first described air-flow accelerates logicalThe entrance in road connects with described pore branch, and the outlet of the first described air-flow accelerated passage is arranged at the top of sprinkler body, shouldFirst air-flow accelerated passage is obliquely installed so that the first air-flow accelerated passage outlet facing to gas-liquid mixed top of chamber go out liquidHole, described spiral cover is provided with the second air-flow accelerated passage, the second air-flow accelerated passage and the connection of the first air-flow accelerated passage,The entrance of the second air-flow accelerated passage connects the outlet of the first air-flow accelerated passage, and the outlet of the second air-flow accelerated passage faces toward gasThe liquid outlet at liquid hybrid chamber top, the central shaft of the first air-flow accelerated passage and the second air-flow accelerated passage is positioned at same straight lineOn.
Further, described water inlet pipe rotates with described sprinkler body with described sprinkler body rotary valve and described sprinkler bodyValve is threaded connection so that hollow tube connects with the inlet opening of water inlet pipe and sprinkler body.
Beneficial effects of the present invention: the Irrigation shower head of the present invention, simple in construction, by the setting of inlet opening structure so thatHydraulic pressure in shower nozzle constantly increases, and is increasing range by improving hydraulic pressure；
Additionally, increase air inlet, on the one hand improve range by increase air pressure, on the other hand by increase air-flow, current are beatenDissipate, improve atomizing effect；This effect is further enhanced by the setting of air-flow accelerated passage.

Detailed description of the invention
Below in conjunction with the accompanying drawings technical scheme is elaborated.
As it is shown in figure 1, be a kind of Irrigation shower head of the present invention, a kind of Irrigation shower head, including water inlet pipe 1, sprinkler body 2 and spiral cover3, spiral cover 3 is set in described sprinkler body 2 top, and can be at sprinkler body 2 rotary-top；It is provided with sprinkler body on water inlet pipe 1 to rotateValve 4；Sprinkler body 2 is rotated by sprinkler body rotary valve 4；
Being provided with inlet opening and air inlet in sprinkler body 2, sprinkler body 2 top is provided with gas-liquid mixed chamber 23, the top in gas-liquid mixed chamber 23Portion arranges liquid outlet 24；Inlet opening all connects with gas-liquid mixed chamber 23 with air inlet；
The circular hole 31 passed for gas-liquid hybrid chamber 23 it is provided with on spiral cover 3.
