[0001] This utility model relates to the technical field of mixed fire extinguishing devices, specifically a portable fire extinguishing device that integrates foam proportioning and high-pressure delivery. Background Technology

[0002] Foam extinguishing is a commonly used handheld method in firefighting operations. Foam effectively isolates the extinguishing agent from the air, greatly improving extinguishing efficiency. Existing foam mixing devices mostly consist of a water tank, foam container, and mixing pump. The mixing pump mixes water and foam before spraying. Current fire extinguishing devices are generally divided into fixed and mobile types. However, mobile devices have several inconveniences. Since the nozzles of mobile devices are mostly fixed to the device, they can only extinguish fires within a designated area as the device moves. In areas where the device cannot move, they cannot operate effectively, resulting in practical limitations. Therefore, those skilled in the art have proposed a portable fire extinguishing device integrating foam proportioning and high-pressure delivery to address the problems mentioned above.
