Description
Technical Field
The utility model relates to the technical field of fire extinguisher equipment, in particular to a nozzle used on a fire extinguisher.
Background
When a liquid fire extinguishing agent is used to extinguish a fire source, a continuous direct current water column is easy to become an electric conductor between a human body and the fire source, leakage current is generated on the human body through the direct current water column, and the higher the voltage of the electrified fire source is, the higher the safety risk is. However, in actual fire extinguishing, the power supply may not be cut off due to production requirements or other reasons, or when a high residual voltage is left after the power supply is cut off, the fire must be extinguished with electricity.
Therefore, the structure of atomizing water is added at the position of the nozzle of the fire extinguisher, so that the nozzle can spray atomized water, and the problem of having an electric fire source is avoided. However, the structure of the existing nozzle is complex, and extra parts are needed, which reduces the assembly efficiency of the nozzle and greatly increases the overall cost of the nozzle.
Based on the above problems, there is a need for improvement of the prior art.

Detailed Description
The utility model is described in further detail below with reference to the following figures and embodiments: referring to fig. 1 to 3, a water mist fire extinguisher nozzle comprising:
the nozzle holder 1 comprises through holes penetrating through the whole nozzle holder, the through holes comprise a first through hole 11 positioned at the front end of the nozzle holder, a second through hole 12 connected with the first through hole 11 and a third through hole 13 connected with the second through hole 12, wherein the first through hole 11 comprises a water outlet 11a positioned at the front end and a taper hole part 11b connected with the water outlet, the positions of the second through hole 12 are the same in caliber, and the caliber of the third through hole 13 is larger than that of the second through hole 12;
the rotor 2 is in a cylindrical shape as a whole, guide grooves 20 distributed in a rotating direction are uniformly arranged on the circumference of the rotor 2, the rotor 2 is arranged in a space formed by the first through hole 11 and the second through hole 12, and the rotor 2 can move in the space but cannot turn over;
the plugging cylinder 3 is abutted against a step 100 formed at the joint of the first through hole 11 and the second through hole 12, the diameter of the front port of the plugging cylinder 3 is smaller than the outer diameter of the rotor 2, so that the rotor 2 is blocked by the plugging cylinder, and a channel 30 for fluid to pass through is arranged on the plugging cylinder 3.
Among the above-mentioned technical scheme, nozzle overall structure is simple, and the equipment is convenient succinct. Specifically, during assembly, the rotor can be directly installed along one side of the second through hole, and then inserted into the second through hole through the blocking cylinder 3 until one end of the rotor is on the step 100 formed by the first through hole and the second through hole, so that the rotor is just in the space formed by the first through hole 11 and the second through hole 12, and a gap is left between the rotor and the side wall of the space, and the size of the gap ensures that the rotor cannot be turned over arbitrarily. When the fire extinguisher is used, under the driving of pressure during spraying, the fire extinguishing agent passes through the rotor, so that the rotor can be rapidly driven to rotate, and the water mist fire extinguishing agent is sprayed out, so that the fire extinguisher achieves the best effect. When the fire extinguisher is used, the water mist is generated, the fire extinguishing performance of the fire extinguisher is improved, the A (solid material fire), the B (combustible liquid fire) and the F (kitchen fire) can be effectively extinguished, and the water mist is thin enough to be non-conductive, so that the E-class electrified material fire can be extinguished.
Specifically, three sets of guiding grooves 20 are provided. The height of the rotor 2 is greater than the diameter of the rotor 2 to ensure that the rotor does not turn over in the space of the nozzle. Preferably, the passage 30 is tapered along a diameter from the rear end to the front end to ensure that the fire extinguishing agent passing through the passage 30 can ensure a large flow velocity through the guiding grooves formed on the rotor to give a larger tangential force to the rotor to form a circular motion.
The foregoing shows and describes the general principles, principal features, and advantages of the utility model. It will be appreciated by persons skilled in the art that the present invention is not limited by the embodiments described above. The foregoing embodiments and description of the utility model have been provided for the purposes of illustrating the principles of the utility model and is subject to various changes and modifications without departing from the spirit and scope of the utility model. Such variations and modifications are intended to be within the scope of the claimed invention.
