Electric water-series fire extinguishing gun

Abstract

The invention discloses an electric water-series fire extinguishing gun. The electric water-series fire extinguishing gun comprises a handheld gun shaped housing, and a built-in type liquid storing device which is arranged in the handheld gun shaped housing, wherein the built-in liquid storing device comprises a flexible deformable liquid bag and a damming preventing dredging device; the damming preventing dredging device comprises a dredging pipe which passes through the flexible deformable liquid bag, and damming preventing rods which are arranged at the upper part and the lower part of the dredging pipe; water holes positioned in the inner side of the flexible deformable liquid bag are closely distributed in the dredging pipe; a movable power supply, an electric water pump and a controller are arranged in the handheld gun shaped housing; the movable power supply is connected to the controller, and the controller is linearly connected to the electric water pump. According to the aforementioned above, the electric water-series fire extinguishing gun has the advantages that the special flexible deformable liquid bag is adopted, so that the utilization rate of a liquid extinguisher can be increased, and the effective jetting distance is greater than 8 meters; a single-finger trigger is simple and convenient to operate; the fire extinguishing work is efficient, and the maintenance is convenient.

Description

technical field [0001] The invention relates to the field of fire extinguishers, in particular to an electric water system fire extinguisher. Background technique [0002] Conventional portable fire extinguishers generally have the following problems: [0003] 1. The effective spray distance is short (3~5 meters). When a fire occurs, it is difficult for people to approach the fire source due to heat radiation and harmful smoke, and it is impossible to extinguish the fire within the effective distance; [0004] 2. When the portable fire extinguisher is used, the powder (dry powder fire extinguisher) is flying, and the utilization rate of the fire extinguishing agent is low and causes certain pollution; [0005] 3. The stored pressure fire extinguisher has certain safety hazards, and the pressure maintenance period is short, and the maintenance cost is high; [0006] 4. The portable fire extinguisher cannot be filled with fire extinguishing agent for repeated use on site, an...
