The device sprays water by using the irrigation spray head when in use and realizes irrigation under the condition that the baffle blocks and disperses, but the device only has the function of irrigation (namely only can spray clean water to fulfill the purpose of irrigation) because the plant needs to be fertilized regularly for the vigorous growth of the plant, so other equipment (such as a fertilizer applicator) is required to be additionally used for fertilization, and the tool cost of agricultural production is increased;

in addition, in the prior art, chinese patent with publication number CN206341678U discloses an automatic garden watering device, which belongs to the technical field of garden appliances. The technical scheme of the utility model is that: including the watering ware fixing base, be provided with the fixed palm of ground connection in watering ware fixing base front side, the fixed palm upside of ground connection is provided with the fixed screw hole, watering ware fixing base downside is provided with the water supply connecting pipe, water supply connecting pipe downside is provided with the water pipe head, water supply connecting pipe left side is provided with the power supply connecting pipe, watering ware fixing base upside is provided with the watering regulation and control section of thick bamboo, watering regulation and control section of thick bamboo left side is provided with the watering settlement ware, watering settlement ware front side is provided with and sets for the closed window, it is provided with the closed window fixed axle to set for closed window left side, it is provided with the handle of opening to set for closed window right side, it is provided with digital display screen to set for closed window rear side. The utility model has the advantages of flexible design and comprehensive functions, can automatically irrigate plants according to setting when the plants are irrigated automatically, is convenient to regulate and control, saves time and labor, and greatly facilitates the irrigation work of workers (8230) \\8230

Above-mentioned device utilizes the shower nozzle to spray the water source to the distant place, thereby reach the purpose of watering, but the shower nozzle damages or ageing condition such as can make the hole position that is used for the water spray to appear breach or jam because of the corrosion in the in-process of using, this condition makes shower nozzle department can appear the condition of dripping and leaking at the during operation, and just start equipment and just close equipment time because water pressure is less makes the water source can't spout the position that needs (promptly drip around equipment), thereby above-mentioned two kinds of condition water all do not spray the waste that the crop position caused the water resource.
