Description

Fire-extinguishing spray header Technical Field The utility model relates to the technical field of spray heads, in particular to a fire extinguishing spray head. Background Fire-extinguishing spray heads (also called fire-extinguishing spray heads) are key components in automatic water-spraying fire-extinguishing systems, and are widely applied to places such as buildings, industries, storage and the like by automatically spraying water to extinguish fire through sensing fire (such as high temperature and flame). The spray head is classified according to the triggering principle, and comprises a thermosensitive spray head which is heated, expanded and broken through a thermosensitive element (such as liquid in a glass ball) to trigger water spraying, a mechanical spray head which is heated, deformed or melted through a mechanical structure (such as fusible alloy and a spring) to start water spraying, and an electronic spray head which is linked with an electromagnetic valve through smoke and a temperature sensor to start (needing a power supply or a signal wire). The existing thermosensitive fire-extinguishing spray head water flows out and then falls on the sprinkler to spray water, but the fire-extinguishing mode of spraying is characterized in that the water flow is too dispersed, the water flow impact force is small, the water resource waste is easy to be caused, and the spray type fire-extinguishing spray head is not suitable for the use of targeted fire-extinguishing points. It is therefore desirable to provide a fire suppression showerhead that addresses the above-described problems. Disclosure of utility model The utility model aims to provide a fire-extinguishing spray head to solve the problems in the background art. In order to solve the technical problems, the utility model is realized by the following technical scheme: The utility model relates to a fire-extinguishing spray head, comprising: The spray head comprises a base, a bracket and a water outlet pipe, wherein one end of the bracket is fixed on the side edge of the base, and the other end of the bracket is fixed on the side edge of the water outlet pipe; The flow gathering assembly comprises a through hole, steel wires and water gathering grooves, wherein the through hole is formed in the upper end of the water outlet pipe, the steel wires are inserted into the through hole, the two ends of the steel wires are bent, the number of the water gathering grooves is four, and the steel wires are formed in the lower end of the water outlet pipe and are distributed in an annular symmetrical mode.
