V. EMBODIMENTS

(5) As shown in FIGS. 1-3, three threaded connecting pipes 2 in length of 100 mm are connected to each other by threads, and a precision digital pressure gauge 1 is connected therebetween to observe the water pressure, and the required water flow pressure can be achieved by adjusting and controlling the valve 3. The low-pressure fine atomizing nozzle 6 is disposed at the outlet of the threaded connecting pipe 2 to jet water flow. A small motor fan 7 is disposed vertically opposite to the low-pressure fine atomizing nozzle 6. The small motor fan 7 consists of a small motor and a fan, wherein, the fan is made of plastic material and has a four-blade propeller, the diameter thereof may be selected according to the required atomization effect, such as 30 mm, 40 mm, 45 mm, or 56 mm. The small motor adopts a Model 130 motor, the motor specification is 15.5*20.3 mm, the motor height is 25 mm, the diameter of output shaft is 2.0 mm, the output shaft length is 8 mm, the rated voltage is 6V, the rotation speed is about 10,000 rpm, and the weight is about 20 g. To further achieve the secondary fragmentation of the jet flow at the nozzle, the small motor fan 7 rotates as the motor is powered by a storage battery pack 9 (a battery case containing four AA dry battery cells, with a cover and a switch), so as to diverge the jet flow; in addition, the low-pressure fine atomizing nozzle 6 can move in the U-shaped slot 14. Both the small motor fan 7 and the storage battery pack 9 are fixed to the bottom slotted bracket, the bottom slotted bracket is connected with the top slotted bracket via a screw rod 5 (a cast iron pole in length of 15-20 mm, with threads along its full length), and the vertical distance between the two slotted brackets can be adjusted by turning an adjustable screw nut 8. The height of the top slotted bracket can be adjusted by screwing and unscrewing of a bolt in a M8 threaded hole 10 in the wall of a pipe fitting hole 11. By moving the screw rod 5 in an open hole 15 of the bottom slotted bracket to the left or right in a U-shaped slot 13, the top slotted bracket and the bottom slotted bracket can move left or right in parallel to each other and the axial distance between the small motor fan 7 and the low-pressure fine atomizing nozzle 6 can be controlled, to achieve a good atomization effect.

(6) The working process is as follows: for example, to sprinkle over a square land in side length of 2 m, a low-pressure atomizing sprinkler is mounted via the threaded connecting pipe to a corresponding frame, and a water pipeline is connected; a threaded connecting pipe in different length may be selected according to the height, so as to adjust the height difference between the nozzle and the plant. An appropriate atomization pressure is realized by adjusting the valve with the aid of the precision digital pressure gauge, and the jet flow is diverged by means of the rotation action of the small motor fan, so as to achieve a good atomization effect. The axial distance between the small motor fan and the low-pressure fine atomizing nozzle can be adjusted by turning the adjustable screw nut on the screw rod, and the lateral distance between the fan and the nozzle can be adjusted by moving the screw rod in the U-shaped slot of the top slotted bracket.
