A fire sprinkler has an inlet pipe and a water nozzle body. The water nozzle body has a water nozzle cover and a water mouth component. A stop valve core, the upper end of which is a stop valve, is mounted inside the water nozzle body. A supporting rack is mounted at a water nozzle lower end. A glass heat sensitive element is vertically mounted in the supporting rack. A stop valve core which is supported via the glass heat sensitive element drops to bias the stop valve from the water inlet, which is situated at the lower end of the induction pipe. A force rotates the water nozzle body on the ball bearing. The centrifugal force from nozzle body rotation provides a parabolic water spray shape for achieving larger area fire extinguishing effect.
