Description

Automatic rotatory sprinkler Technical Field The invention relates to a sprinkler for landscaping irrigation, in particular to an automatic rotating sprinkler. Background At present, an automatic rotating sprayer is needed for landscaping irrigation, and the automatic rotating sprayer mainly comprises a spray pipe, a water inlet channel arranged in the spray pipe, a mounting sleeve movably sleeved at the bottom of the spray pipe and the like, and is fixedly arranged in a water inlet disc through the mounting sleeve, so that when the water inlet disc supplies water into the water inlet channel and sprays irrigation from the top of the body, the body is driven to rotate relative to the mounting sleeve under the influence of water inlet pressure, and 360-degree spraying irrigation can be formed. However, in some occasions, the spraying irrigation does not need 360 degrees, but only needs to swing left and right to spray in a certain angle, at this time, corresponding mechanisms are required to be designed for swing limiting, the structural design of the existing mechanisms is simpler, and the spraying angle is limited by adopting an exposed movable plectrum to block a spraying opening, so that the structure is exposed, the structure is easy to damage in actual use, the use reliability is poor, the appearance is very unsightly due to the too simple structure, and in addition, along with the continuous expansion of the landscaping irrigation market, many consumers are also urgent to push out more automatic rotary sprayers with different structures and embodiments so as to meet the market purchase needs. Disclosure of Invention The technical problem to be solved by the invention is to overcome the defects of the prior art and provide an automatic rotating sprinkler which is attractive in appearance, compact in structure and reliable in use. The technical problems of the invention are realized by the following technical scheme: The automatic rotary sprinkler comprises a sprinkler tube, a water inlet channel arranged in the sprinkler tube and a mounting sleeve movably sleeved at the bottom of the sprinkler tube, wherein an air inlet cavity and an elastic blocking mechanism arranged in the air inlet cavity are arranged outside the sprinkler tube, the elastic blocking mechanism is provided with a switching deflector, left air supplementing holes and right air supplementing holes communicated with the water inlet channel are respectively arranged on two sides of the top of the sprinkler tube, the left air supplementing holes and the right air supplementing holes are respectively communicated with the air inlet cavity through left air supplementing channels and right air supplementing channels, the elastic blocking mechanism is driven by the switching deflector to alternately block the left air supplementing channels and the right air supplementing channels, the water inlet in the water inlet channel is sprayed out by the top of the sprinkler tube to cause left and right pressure imbalance, and further the sprinkler tube is driven to spray water in a left swinging mode and a right swinging mode relative to the mounting sleeve, and the switching deflector is driven simultaneously to alternately block the left air supplementing channels and the right air supplementing channels, and further form continuous automatic left and right swinging water spraying of the sprinkler tube. The elastic blocking mechanism comprises a reversing rod and a switching deflector rod, wherein a blocking ball head is arranged at the top end of the reversing rod, the bottom end of the reversing rod is hinged with the top end of the switching deflector rod, the bottom end of the switching deflector rod downwards extends out of the air inlet cavity, an elastic connection tension spring is arranged between the reversing rod and the switching deflector rod, the spray pipe is oppositely arranged to the left and right swinging water spray of the sleeve to drive the bottom end of the switching deflector rod to form left and right swinging at the same time, and the blocking ball head at the top end of the reversing rod is pulled by the tension spring to swing left and right to alternately block the left and right air supplementing channels. The spray pipe consists of a body, a nozzle arranged at the top of the body in a sealing way and a mandrel arranged at the bottom of the body in a sealing way, wherein water inlet channels which are mutually communicated are arranged in the nozzle, the body and the mandrel. The installation sleeve is movably sleeved outside the mandrel, and the mandrel rotates back and forth relative to the installation sleeve to drive the nozzle to spray water in a left-right swinging way. The body is provided with a housing, and an air inlet cavity is formed between the housing and the body. The two sides of the housing are respectively provided with a left air inlet hole and a right air inlet hole which are communicated with the a
