Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of fire extinguishers, and particularly relates to a trolley type fire extinguisher for lithium batteries. BACKGROUND

[0002] Lithium batteries are a kind of batteries with lithium metal or lithium alloy as a negative electrode material and using a non-aqueous electrolyte solution, and a fire extinguisher needs to be used to extinguish the lithium battery when it is on fire. Most of the fire extinguishers used for lithium batteries are water-based fire extinguishers. After the water-based fire extinguisher is sprayed, it is in the form of water mist, also known as a water mist type fire extinguisher.

[0003] The existing Chinese patent with the publication number CN109771867B discloses a hand-held fine water mist fire extinguishing device for lithium batteries, and relates to the field of fire extinguishing devices. The hand-held fine water mist fire extinguishing device for lithium batteries comprises a tank body and a handle. The handle is movably connected to the top of the tank body. The side surface of the tank body is fixedly connected with a square tube. The inner wall of the square tube is movably connected with the surface of a square rod. The top of the square rod is fixedly connected with a connecting rod. The top of the connecting rod is fixedly connected with the bottom of a movable rod. The movable rod is located below the handle. The inner wall of the square tube is provided with a square groove. The surface of the square rod is fixedly sleeved with a square ring.

[0004] Although the above-mentioned fire extinguisher improves the convenience of hand-holding, the hand-held fire extinguisher has a small capacity of fire extinguishing agent, and the capacity of fire extinguishing agent may be insufficient when dealing with the fire of lithium batteries. Therefore, improvement is needed. CONTENT OF THE UTILITY MODEL
