[0050] In one preferred embodiment of the present application, the liquid supply assembly 400 is also included in the present application, the liquid supply assembly 400 includes a water tank 410, a water pump 420 and a winding member 430, the water pump 420 is communicated with the water tank 410 through a liquid inlet pipe 421, a liquid outlet of the water pump 420 is connected with a liquid supply pipe 440, the liquid supply pipe 440 is wound on the winding member 430, the winding member 430 is used for winding and unwinding the liquid supply pipe 440, and the liquid supply pipe 440 is detachably connected with the atomizing nozzle 225 through a water inlet pipe 450; the water pump 420 is electrically connected with the control assembly 300.

[0051] Specifically, the water tank 410 is arranged at a place where water is easy to add, such as near a ditch, near a greenhouse exit, etc. The water pump 420 is connected with the water tank 410 through the liquid inlet pipe 421. A filter screen is arranged at the water outlet of the water tank 410 to avoid sundries falling into the water tank 410 from entering the liquid inlet pipe 421. The liquid outlet of the water pump 420 is connected with the liquid supply pipe 440. The material of the liquid supply pipe 440 needs to be comprehensively considered in terms of corrosion resistance, flexibility, durability, cost and food safety, such as food-grade linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE), UV-resistant LLDPE pipe material, food-grade silicone tube, etc. A plurality of connecting ports are arranged on the liquid supply pipe 440.

After the liquid supply pipe 440 is stretched, at least one circle of the liquid supply pipe 440 is left on the winding member 430, and at most one layer of the liquid supply pipe 440 is left on the winding member 430. The winding member 430 adopts, but is not limited to, a hand winding wheel 431 and a motor winding wheel 431.

[0052] Further, in the initial state, the liquid supply pipe 440 is completely wound on the winding member 430.

Then the operator connects the atomizing nozzles 225 to the connecting ports of the liquid supply pipe 440 in sequence through the water inlet pipes 450. Conversely, when disassembling, the water inlet pipe 450 on the connecting port is removed first, then the end of the liquid supply pipe 440 away from the winding member 430 is removed, and then the winding member 430 is opened to wind the liquid supply pipe 440 on the winding wheel 431, so as to be used next time. By arranging the winding member 430, the problem of high labor intensity and low recovery efficiency of manually recovering the liquid supply pipe 440 is solved. At the same time, when manually recovering, the liquid in the liquid supply pipe 440 is not discharged, which causes difficulty in manual recovery and easily causes coiling and knotting.

[0053] In one scheme of the present application, the water inlet pipe 450 comprises a water inlet part 451, a water outlet part 453 and a corrugated stretch part 452, the water inlet part 451 is connected to the liquid supply pipe 440, and the water inlet part 451 is detachably connected to the fixed end 222 of the electrically controlled telescopic rod 220 near the corrugated stretch part 452, the water outlet part 453 is connected to the atomizing nozzle 225, and the water outlet part 453 is detachably connected to the telescopic end 223 of the electrically controlled telescopic rod 220 near the corrugated stretch part; the corrugated stretch part 452 can be telescoped under the driving of the electrically controlled telescopic rod 220.

[0054] Specifically, the water inlet pipe 450 adopts a hose, and the length is adjusted according to the distance from the liquid supply pipe 440 to the atomizing nozzle 225, the length of the water inlet part 451 of the water inlet pipe 450 is the longest, the length of the corrugated stretch part 452 is not less than the limit elongation length of the electrically controlled telescopic rod 220, the water outlet part 453 adopts a hard pipe, and the length is the length from the atomizing nozzle 225 to the fixed end 222 of the electrically controlled telescopic rod 220; and the two ends of the water outlet part 453 are detachably connected to the atomizing nozzle 225 and the telescopic end 223 of the electrically controlled telescopic rod 220 respectively by using a third bearing to match a belt, silk binding and other methods, for example, the inner shaft of the third bearing is connected to the telescopic end 223 of the electrically controlled telescopic rod 220, and the outer shaft of the third bearing is detachably connected to the water outlet part 453 by using silk binding, belt binding and other methods; similarly, the water inlet part 451 and the fixed end 222 of the electrically controlled telescopic rod 220 are detachably connected by using the same method (the connection is connected by using a fourth bearing). By arranging the corrugated stretch part 452, the problem that the water inlet pipe 450 swings back and forth and is prone to falling off and leaking at the connection when the electrically controlled telescopic rod 220 telescopes is solved.

[0055] Based on the above scheme, the fixed end 222 of the electrically controlled telescopic rod 220 is provided with a sleeve 228, the water outlet part 453 penetrates through the sleeve 228 and is connected to the atomizing nozzle 225, the corrugated stretch part 452 is arranged in the sleeve 228, and the length of the sleeve 228 is not less than the limit stretch length of the corrugated stretch part 452.
