Description

Technical Field

[0001] The utility model belongs to the technical field of spraying equipment, in particular to a piston type atomizing nozzle. Background Art

[0002] Atomizing nozzle is a kind of farmland irrigation equipment that sprays pressurized water into the air through the nozzle and scatters it in the field and crops in the form of mist. It is suitable for flower fields, lawns, green spaces, factories, greenhouses, and agricultural water-saving irrigation. Standard air atomizing nozzle optional components include: automatically operated cylinder, cleaning needle, siphon or gravity feeding configuration, internal or external mixing device, etc.

[0003] The Chinese patent discloses an atomizing nozzle (CN208288274U), which includes an end cap and a nozzle body. The end cap is provided with a nozzle for spraying liquid droplets and gas. The end cap is installed at the end of the nozzle body and an air chamber is formed between the end cap and the nozzle body. The nozzle body is provided with a gas groove for inputting gas into the air chamber and a liquid outlet pipeline corresponding to the nozzle position. The gas flow direction in the air chamber obliquely cuts the liquid droplets sprayed from the liquid outlet pipeline to the nozzle. The atomizing nozzle of the utility model does not need to have a very high working pressure, can provide stable particle size droplets, and has a low system cost. Most of the current atomizing nozzles do not have a self-cleaning function and are easily blocked by impurities in water in daily use, thereby reducing the atomization effect and water output of the atomizing nozzle. If it is not cleaned frequently, it is easy to cause damage to the atomizing nozzle. For this purpose, a piston-type atomizing nozzle is provided. Utility Model Content

[0019] 2. In the utility model, a pressing assembly is provided to press the pressing rod into the fixed cover, thereby driving the piston plate to move in the piston cylinder. At the same time, the telescopic spring is in a stretched state. As the piston plate moves, the water in the piston cylinder is squeezed. At this time, the water is sprayed out from the atomizing head through the water outlet pipe. The structure is simple and not easy to be damaged. The atomized water output can be changed by controlling the length of the pressing rod, thereby improving the control convenience of the atomizing nozzle. BRIEF DESCRIPTION OF THE DRAWINGS

The pressing assembly 3 includes a piston cylinder 31, and the side wall of the piston cylinder 31 is fixedly connected to the inner side wall of the fixed cover 2. A piston plate 34 is slidably installed on the inner wall of the piston cylinder 31, and a telescopic spring 35 and a pressing rod 36 are fixedly installed on the side wall of the piston plate 34.

[0032] The specific implementation method is as follows: the atomizing nozzle is connected to the spray pot through the threaded cover 1, and the water inlet pipe 7 is inserted into the water in the spray pot. The pressing rod 36 is pressed into the fixed cover 2, and the piston plate 34 is driven to move in the piston cylinder 31. At the same time, the telescopic spring 35 is in a stretched state. As the piston plate 34 moves, the water in the piston cylinder 31 is squeezed. At this time, the water is sprayed out from the atomizing head 37 through the water outlet pipe 32, and the squeezing of the pressing rod 36 is released. Under the action of the telescopic spring 35, the piston plate 34 is driven to return to its original position.

[0033] Working principle: The atomizing nozzle is connected to the spray pot through the threaded cover 1. At this time, the water inlet pipe 7 is inserted into the water in the spray pot, and the pressing rod 36 is pressed into the fixed cover 2. At this time, the piston plate 34 is driven to move in the piston cylinder 31. At the same time, the telescopic spring 35 is in a stretched state. As the piston plate 34 moves, the water in the piston cylinder 31 is squeezed. At this time, the water is sprayed out from the atomizing nozzle 37 through the water outlet pipe 32. The squeezing of the pressing rod 36 is released. Under the action of the telescopic spring 35, the piston plate 34 is driven to return to its original position. At this time, under the connection of the connecting pipe 33, the water in the temporary storage cylinder 6 is sucked into the piston cylinder 31, and the water in the spray pot is sucked out by the water inlet pipe 7. The water is sucked into the temporary storage tube 6. When the pressing rod 36 moves into the piston tube 31, the transmission gear 53 drives the rotating rod 52 to rotate forward under the action of the fixed rack 8. The ratchet 59 and the ratchet ring 54 are not engaged, so the reciprocating screw 510 does not rotate. When the pressing rod 36 moves to the outside of the fixed cover 2, the fixed rack 8 flips the rotating rod 52 through the transmission gear 53. Under the action of the ratchet 59 and the ratchet ring 54, the reciprocating screw 510 rotates. Under the action of the outer surface thread, the threaded sleeve 511 moves up and down one back and forth, and under the action of the support rod 512, the cleaning plate 513 is driven to clean the atomizing head 37.
