When the water pressure is low, it is easy to drip on the water pipe and easily burst the water pipe, which is inconvenient for workers to operate and reduce the service life.

[0003] Patent document CN205146479U discloses a spring atomizing nozzle, which discloses "a spring atomizing nozzle, relating to a nozzle. At present, since the outlet cross-section of the nozzle is constant, the water spraying speed will decrease accordingly when the flow rate decreases. The utility model includes a spray rod, an upper spray seat, a lower spray seat, and a spring located between the upper spray seat and the lower spray seat, and the spray rod is fixed to the upper spray seat; the lower part of the spray rod is a conical nozzle with a larger bottom and a smaller top, and the lower spray seat is provided with an atomizing chamber opening downward and an atomizing hole connected to the atomizing chamber, and the opening of the atomizing chamber is conical and matches the nozzle."

The front side of the baffle is fixedly connected to the pull rod. The front end of the pull rod is fixedly connected to the intercepting plate. When water is output, water passes through the inside of the movable port, and the water pushes the intercepting plate to move. The intercepting plate drives the pull rod to move forward, and the pull rod drives the baffle to move. The baffle squeezes the second return spring, causing the second return spring to contract. When water flows back, the second return spring stretches to make the intercepting plate press against the front wall of the support ring to prevent backflow.

[0015] 2. The utility model is equipped with an external thread, and an external thread is set on the outer side of the movable rod.
