Problems solved by technology
[0002] In the field of fire protection, fire nozzles are used in fire sprinkler systems. When a fire breaks out, water is sprayed from the fire nozzles to perform fire extinguishing operations, but for the existing fire nozzles, the problem that it exists is that the Water often contains impurities such as rust blocks and particles. When these impurities accumulate in the fire nozzle, it will cause the fire nozzle to block, so that it cannot work normally when a fire occurs. In order to prevent blockage, some fire nozzles use filters, but Due to structural design constraints, the filter is prone to deformation and damage under the impact of high-pressure water flow, and at the same time, the filtered impurities cannot be easily cleaned, which seriously affects the performance of the fire nozzle

Abstract
The invention relates to a novel fireproof nozzle. The novel fireproof nozzle comprises a main water spraying pipe. A plurality of water spraying ports are formed in the outer side wall of the part, close to the right end of the main water spraying pipe, of the main water spraying pipe. Branch water spraying pipes and sprayers are arranged at the water spraying ports. A water inlet cavity is formed in the outer portion of the part, located on the left sides of the branch water spraying pipes, of the main water spraying pipe. A water inlet is formed in the left end of the water inlet cavity. A plurality of water passing holes are distributed in the outer circumferential side wall of the part, located in the water inlet cavity, of the main water spraying pipe, and the outer circumferential side wall is covered with a filtering net. Meanwhile, the outer portion of the part, located on the left side of the filtering net, of the main water spraying pipe is fixedly connected with annular protection plates. A top cleaning port and a bottom cleaning port are formed in the top and the bottom of the water inlet cavity respectively. The top cleaning port and the bottom cleaning port are provided with a top cover and a bottom cover respectively. By means of the structure, water flow can be effectively filtered, meanwhile, it is guaranteed that the filtering structure is not prone to damage, and filtered-out impurities can be easier to remove.
