Description

Lifting type spray header assembly for irrigation gardens or farms Technical Field The present utility model relates to a spray apparatus for irrigating gardens or farms, and more particularly, to a lifting type spray head assembly which lifts a spray head by water pressure to open a circumferential spray jet. Background A shower head assembly for gardens or farms is a key component in an irrigation system, mainly for uniformly spraying water onto plants or crops, and comprises: the spray head main body is provided with one or more water spray holes, and water is sprayed out through the holes to form a spray effect. The filter screen is generally positioned at the water inlet of the nozzle body and is used for filtering impurities in water. The rotating mechanism is arranged on some spray header components, and can enable the spray heads to rotate around a certain axis, so that the water spraying range is enlarged, and more uniform irrigation is realized. The rotating mechanism is usually composed of a motor, a gear or a worm gear, etc., and the spray head is driven to rotate by power. When the irrigation system is started, water is delivered under pressure through the pipes to the showerhead assembly. First, water is filtered through a filter screen and then enters the spray head body. In the spray head body, the pressure energy of the water is converted into kinetic energy, high-speed spraying from the water spraying hole. If the spray head is provided with a rotating mechanism, a motor or other power device can drive the spray head to rotate, so that water is sprayed to surrounding areas at a certain angle and range. The electromagnetic start-stop type garden water gun of CN105900799A is provided with a crank sprinkler with adjustable spraying angle, a gear set gear, an electromagnetic flowmeter, a water throwing device, a 360-degree spray head, a water distributor and the like.
