Household mixed foam type fire fighting sprayer

Abstract

The invention belongs to the field of household fire fighting, and relates to a household mixed foam type fire fighting sprayer. The household mixed foam type fire fighting sprayer comprises a shell, an air exhaust cavity is formed in the shell, an air exhaust device is arranged in the air exhaust cavity, and the air exhaust device is used for rapidly exhausting hot air from bottom to top so as to drive the device to operate; and a meshing transmission cavity is formed in the shell, and a meshing transmission device is arranged in the meshing transmission cavity. According to the household mixed foam type fire fighting sprayer, when a fire occurs in environments such as a home, the spraying force can be adjusted according to the size of the fire behavior, the device can spray water for fire fighting and extinguishment, the use of a mixed foam extinguishing agent can be judged according to the fire behavior, and the foaming agent is stirred and extruded out from the device when the fire behavior is large and is mixed with internal spraying water pressure to generate a large amount of foam, so that the household mixed foam type fire fighting sprayer is suitable for various fire behaviors such as oil, electricity and inflammables; and under the conditions, the household mixed foam type fire fighting sprayer can also expand a spraying part to enlarge a spraying area, the spraying range is widened, the spraying amount is increased, and fire extinguishing is accelerated.

Description

technical field [0001] The invention belongs to the field of household fire protection, in particular to a household mixed foam type fire sprinkler. Background technique [0002] The fire sprinkler head is used in the fire sprinkler system.

Problems solved by technology

In order to extinguish the fire in time, the fire protection system needs to make many changes. First, when the smoke alarm is triggered, can the fire sprinkler be opened in time to extinguish the fire? And the normal fire sprinkler can't control the spraying intensity, distinguish between the small fire and the raging fire to extinguish it in a targeted manner. If the fire is small, if the spraying force is large, it will easily cause damage to equipment and instruments in other unfired areas, resulting in redundant and unnecessary fires. loss
