Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing equipment technology, specifically to an ultra-fine water mist fire extinguishing device. Background Technology

[0002] Backpack-mounted high-pressure fine water mist fire extinguishers are a type of efficient and convenient firefighting equipment, mainly used to extinguish various types of fires. Their working principle involves atomizing water into fine particles under high pressure, forming a large-area mist-like water curtain that rapidly absorbs heat and cools the flames, ultimately extinguishing the fire through oxygen deprivation. The backpack design enhances the mobility and flexibility of firefighters, making it suitable for use in complex terrain and long-distance travel situations, such as forest firefighting.

[0003] The existing backpack-type high-pressure fine water mist fire extinguisher mainly consists of a detachable water bag, a pump body, a frame, and a water gun. However, due to the short connecting pipe between the pump body and the detachable water bag, the backpack-type high-pressure fine water mist fire extinguisher can only draw water from inside the water bag. When there is a water source nearby, it cannot draw water to extinguish the fire, which reduces the practicality of this fire extinguisher.

[0004] Therefore, this utility model provides an ultra-fine water mist fire extinguishing device. Utility Model Content
