（Two）Sprinkler height adjustment process；

S2：First power drive mechanism 200 can also be driven rotary force, the second power transmission machine to the second power drive mechanism 500 The power output end of structure 500 is connect with height adjustment device 600, and the rotary force of axle 120 passes through the first power drive mechanism 200 While being transferred to liquid sprayer 400, which is also transmitted to the second power drive mechanism 500 and by the second power Transmission mechanism 500 is transferred to height adjustment device 600, and the height adjustment device 600 includes rotating mechanism 610, triggering machine Structure 620, pushing mechanism 630, main running rail 640, sliding component 650, the pushing mechanism 630 include pushing member, switching structure Part, the nozzle 460 are installed on sliding component 650, and the sliding component 650 is contacted with pushing member and sliding component 650 match with main running rail 640, and power is transferred to rotating mechanism 610 and makes rotation by second power drive mechanism 500 Mechanism 610 rotates, and the closure switch 420 are set to the side of trigger mechanism 620, and closure switch 420, which are in, to be pressed and connect When logical state, closure switch 420 can make trigger mechanism 620 be triggered to 620 transmitting forces of trigger mechanism, and make rotating machine Structure 610 is in contact condition with pushing mechanism 630, and rotating mechanism 610, which rotates, makes the pushing member in pushing mechanism 630 push cunning Dynamic component 650 is moved upwards along the guide direction of main running rail 640, and during this, the height of nozzle 460 gradually increases, and works as nozzle When 460 height reaches maximum value, the switching member makes pushing member counter motion, and the rotation of rotating mechanism 610 at this time makes Pushing member pushes sliding component 650 to be moved downward along the guide direction of main running rail 640, during this, the height of nozzle 460 by It is decrescence small；

（Three）Sprinkler height fixation procedure；

S3：The pushing mechanism 630 further includes locking unit, when the height of nozzle 460 is in best spraying altitude, is closed Switch 420 is in fully switched on state, and closure switch 420 can eliminate the active force transmitted to trigger mechanism 620 and cancel to touching The triggering of mechanism 620 is sent out, and rotating mechanism 610 is made to be in disengaged position, while the locking unit pair with pushing mechanism 630 Pushing member carries out locking limitation, and then the height of nozzle 460 is made to immobilize, and nozzle 460 is in best spraying altitude.

The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention； Various modifications to these embodiments will be apparent to those skilled in the art, defined in the present invention General Principle can not depart from the present invention spirit or scope in the case of, realize in other embodiments.Therefore, originally Invention will not be defined to the embodiments shown herein, and be to fit to and the principles and novel features disclosed herein Consistent widest range.

Claims
