Description

Self-adaptive watering spray head Technical Field The invention belongs to the technical field of watering spray heads, and particularly relates to a self-adaptive watering spray head. Background In the fields of agricultural irrigation, landscaping, courtyard irrigation and the like, the single-hole watering spray head is widely applied due to the simple structure and low cost. In the prior art, such spray heads typically control the spray distance of the water flow by adjusting the water pressure of the incoming water. However, this single adjustment mode has the significant drawbacks of requiring increased water pressure to achieve a longer range when irrigation is desired in a far area, but where the water flow is concentrated and the coverage area is small, and of requiring reduced water pressure to cause natural scattering of the water flow when irrigation is desired in a near area, where the concentrated water flow results in uneven distribution of water to the landing site, which in turn results in insufficient range and ineffective coverage of the near area. Therefore, users have to frequently and manually adjust the water pressure or replace the spray heads according to the irrigation distance in actual use, the operation is complex, the efficiency is low, and the intelligent and automatic optimal irrigation effect is difficult to realize. The market is urgent to need a shower nozzle structure that can adjust rivers form according to actual operating mode automatically to give consideration to long shot and near watering demand.

The self-adaptive watering spray head can control water flow not to scatter to achieve a longer spraying distance when the self-adaptive watering spray head is used for watering at a distant place, and can diffuse water flow to spray a larger area when the self-adaptive watering spray head is used for watering at a near place. The problem that a user needs to manually adjust the spraying mode when the irrigation distance is changed in the related art is solved, and the degree of automation and the convenience in use of irrigation are improved. The pressure sensing diaphragm is communicated with the inner cavity of the nozzle, the pressure sensing driving mechanism further comprises an elastic reset piece, a pressing fixing part and a pressing fixing part, the elastic reset piece is acted on the water retaining mechanism to provide acting force for driving the water retaining mechanism to move towards the second position, the pressing fixing part is arranged at the end part of the elastic reset piece and used for compressing and fixing the elastic reset piece, and the pressure sensing diaphragm responds to driving force generated by water pressure change of the inner cavity of the nozzle and is used for overcoming the acting force of the elastic reset piece to drive the water retaining mechanism to move towards the first position.
