A method for changing the injection elevation angle of a water-saving irrigation spray head comprises the following steps:
the rotation of the friction wheel 16 drives the jet elevation converter 51 to rotate integrally along the axis O under the action of rolling friction, so that the first flat jet ejection port 6.1, the second flat jet ejection port 6.2, the third flat jet ejection port 6.3, the fourth flat jet ejection port 6.4, the fifth flat jet ejection port 6.5, the sixth flat jet ejection port 6.6, the seventh flat jet ejection port 6.7 and the eighth flat jet ejection port 6.8 are periodically communicated with the jet window 10 one by one.
The working principle and the detailed working process of the scheme are as follows:
the constant pressure water supply pipe 95 continuously supplies constant water pressure to the water inlet cavity 20 in the water inlet seat 19, so that the water pressure in the water transition cavity 15 and the annular water inlet channel 8 is always consistent with the water pressure in the constant pressure water supply pipe 95; because the rotation of the jet elevation converter 51 along the axis O can enable the eight flat jet ejection outlets 6 to be sequentially communicated with the jet window 10, and the flat jet ejection outlets 6 which are not communicated with the jet window 10 are all communicated with the annular water inlet channel 8, under any condition, at least seven flat jet ejection outlets 6 in the eight flat jet ejection outlets 6 are communicated with the annular water inlet channel 8, and because one ends of all the jet channels 1 close to the axis O are all communicated with the annular water distribution cavity 3, the annular water inlet channel 8 is communicated with the annular water distribution cavity 3 through at least seven jet channels 1, so that the water pressure in the annular water distribution cavity 3 is always kept consistent with the water pressure in the annular water inlet channel 8 and the water transition cavity 15; so that the water pressure of the constant pressure water supply pipe 95 can be always transmitted to the annular water distribution chamber 3;
the first flat jet flow ejection opening 6.1 is communicated with the middle part of the jet flow window 10 in an initial state, at the moment, an included angle formed by a first jet flow extension line 7.1 of the first jet flow channel 1.1 and a horizontal plane is 45 degrees, under the water pressure in the annular water distribution cavity 3, water in the annular water distribution cavity 3 is ejected from the first flat jet flow ejection opening 6.1 through the first jet flow channel 1.1 obliquely and upwards from the jet flow window 10 at an initial ejection angle of 45 degrees in elevation angle, and finally falls onto a distant vegetation area, under the condition of the same initial jet flow, the falling distance of the spray when the ejection elevation angle is 45 degrees is the farthest, and the falling distance of the spray is gradually reduced by gradually increasing the ejection elevation angle on the basis of 45 degrees in elevation angle;
at this time, the motor 29 is controlled to rotate the friction wheel 16, and the rotation of the friction wheel 16 drives the whole jet elevation converter 51 to rotate along the axis O under the action of rolling friction, so that the first flat jet ejection port 6.1, the second flat jet ejection port 6.2, the third flat jet ejection port 6.3, the fourth flat jet ejection port 6.4, the fifth flat jet ejection port 6.5, the sixth flat jet ejection port 6.6, the seventh flat jet ejection port 6.7 and the eighth flat jet ejection port 6.8 are periodically connected to the jet window 10 one by one;

meanwhile, the water flowing upwards in the water channel 18 can continuously drive the spiral hydraulic blades 24 or the axial flow hydraulic impeller, so that the rotary cylinder 25 rotates, and the spray head 100 can synchronously rotate along with the rotary cylinder 25; thereby changing the orientation of the jet flow window 10 in real time and further improving the effective jet distance of the spray head.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
