Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, and more specifically, it relates to a portable high-pressure fine water mist fire extinguisher. Background Technology

[0002] In existing high-pressure fine water mist fire extinguishing technology, although the overall structural design is relatively reasonable, there are still many problems with the horizontal and rotational adjustment of the atomizing components in actual application. In particular, the installation and disassembly of the atomizing components are not convenient to operate. These problems not only affect the efficiency of fire extinguishing equipment, but also increase the difficulty of maintenance and repair.

[0003] Currently, in the design of most high-pressure fine water mist fire extinguishers, the atomizing components need to be adjusted for tilting and rotation angles via manual or electric devices. Since these operations usually require a large amount of manpower or mechanical assistance, and the adjustment mechanisms are mostly complex gear systems or hydraulic drive systems, the adjustment is not smooth enough.

[0004] In existing technologies, the installation and disassembly of atomizing components still present many challenges. In the design of most high-pressure fine water mist fire extinguishers, the atomizing components need to be fixed by multiple connecting parts, which is both time-consuming and labor-intensive. Especially in emergencies, operators may need to quickly install or replace the atomizing components, but due to the cumbersome installation process, time is often wasted, reducing emergency response efficiency. When the atomizing components malfunction, operators need to disassemble them to troubleshoot the problem. Due to the complexity of the installation and disassembly process, delays in the repair process will directly affect the availability of the equipment. Especially during a fire, the downtime of the fire extinguishing equipment will reduce the fire extinguishing efficiency. Utility Model Content
