Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishers and discloses a nozzle of a fire extinguisher. Background Art

[0002] Fire extinguishers are important equipment for fire fighting. There are many types of fire extinguishers, including foam-type fire extinguishers and water-based fire extinguishers. The fire extinguishing agent in water-based fire extinguishers is mainly a mixture of clean water and other fire extinguishing materials. Water-based fire extinguishers mainly rely on water vaporization to absorb heat to cool the fire site to achieve the effect of fire extinguishing. When the fire extinguishing material sprayed from the nozzle of the water-based fire extinguisher is in the form of spray mist, it can effectively enhance the heat exchange effect between water and fire, achieve better cooling and suffocation effects, and improve the fire extinguishing effect;

[0003] The nozzle of the existing fire extinguisher nozzle is usually in the shape of a small tube, and the fire extinguishing material is usually in the shape of a water column when sprayed out. The spray range of the fire extinguisher nozzle is small, and the atomization degree of the generated water mist is not sufficient, so it is difficult to achieve a good fire extinguishing effect. Utility Model Content

[0004] The purpose of the utility model is to provide a fire extinguisher nozzle in view of the above-mentioned problems and shortcomings, so that the sprayed fire extinguishing material can be more fully atomized and dispersed, the spraying range of the fire extinguishing material can be expanded, and the fire extinguishing effect can be effectively improved.

[0005] The fire extinguisher nozzle comprises a main body, wherein a thread groove is formed on the left side of the main body;

[0006] A connector is provided on the left side of the thread groove, the right end of the connector is screwed into the thread groove, and a mounting assembly is provided between the connector and the main body;

[0007] A receiving groove is provided at the bottom of the thread groove, a connecting tube is connected to the inside of the receiving groove, a spray tube is connected to the right end of the main body, a plurality of spiral grooves 2 are provided on the inner wall of the spray tube, a through hole communicating with the spray tube is provided on the right side of the receiving groove, a rotating block is provided inside the through hole, and a plurality of spiral grooves 1 are provided on the outer wall of the rotating block.

[0008] Furthermore, a rubber pad is attached to the bottom of the thread groove, the rubber pad is attached to the right side of the connector, the right end of the through hole is funnel-shaped, and the inner wall of the spray barrel is funnel-shaped.

[0009] Furthermore, the installation assembly includes magnet one, magnet two and an insertion rod, and slots are provided on the upper and lower sides of the outer wall of the connector.

[0010] Furthermore, the magnets are provided with two pieces and are respectively embedded and installed in the bottoms of the two slots, the insertion rods are provided with two pieces and are respectively inserted into the upper and lower ends of the main body, and a ring is provided at the outer end of the insertion rod.

[0011] Furthermore, the second magnet is provided with two pieces and is respectively connected to the inner ends of the two insertion rods, and the second magnet and the first magnet are attracted to each other.

[0012] The beneficial effects of the utility model are as follows:

[0013] When the fire extinguisher nozzle is in use, after the main body is screwed onto the outside of the connector, the main body and the connector are limited by the insertion rod, which effectively ensures the stability of the main body during installation and prevents the main body from falling off during subsequent use of the fire extinguisher, affecting the fire extinguishing work;

[0014] The fire extinguishing material can enter the main body through the connecting head. At this time, the fire extinguishing material can enter the through hole through the connecting tube. The inner diameter of the connecting tube decreases from left to right. The flow rate and pressure of the fire extinguishing material will accelerate after passing through the connecting tube. The pressure will increase after the fire extinguishing material enters the through hole. The pressure material can flow through the spiral groove 1 on the outer wall of the rotating block, thereby driving the rotating block to roll inside the through hole, so that the fire extinguishing material can be initially atomized. The fire extinguishing material can enter the nozzle through the through hole. The atomized fire extinguishing material continues to be refined along the spiral groove 2 on the inner wall of the nozzle for spraying, so that the fire extinguishing material finally sprayed from the nozzle is more fully atomized and dispersed, expanding the spraying range of the fire extinguishing material and effectively improving the fire extinguishing effect.

[0020] The bottom of the thread groove 4 is provided with a receiving groove 6, the inside of the receiving groove 6 is connected with a connecting tube 7, the right end of the main body 1 is connected with a spray tube 3, the inner wall of the spray tube 3 is provided with a plurality of spiral grooves 11, the right side of the receiving groove 6 is provided with a through hole 8 communicating with the spray tube 3, the inside of the through hole 8 is provided with a rotating block 9, and the outer wall of the rotating block 9 is provided with a plurality of spiral grooves 10;

[0021] The bottom of the thread groove 4 is fitted with a rubber pad 5, and the rubber pad 5 is fitted with the right side of the connector 2. The installation assembly includes a magnet 13, a magnet 2 14 and a plug rod 15. The outer wall of the connector 2 is provided with slots 12 on the upper and lower sides. The magnet 1 13 is provided with two pieces and is respectively embedded and installed in the bottom of the two slots 12. The plug rod 15 is provided with two pieces and is respectively inserted into the upper and lower ends of the main body 1. The outer end of the plug rod 15 is provided with a ring. The magnet 2 14 is provided with two pieces and is respectively connected to the inner ends of the two plug rods 15. The magnet 2 14 and the magnet 1 13 are adsorbed on each other;

[0022] When using a fire extinguisher nozzle, Figure 1 As shown, grasp the main body 1 and screw it on the outside of the right end of the connector 2. When the right end of the connector 2 is screwed to the bottom of the threaded groove 4, it can fit with the rubber pad 5 at the bottom of the threaded groove 4, thereby improving the sealing of the connection between the main body 1 and the connector 2. At the same time, the plug rod 15 on the main body 1 corresponds to the slot 12 on the connector 2. The plug rod 15 is inserted into the slot 12. The magnet 2 14 at the inner end of the plug rod 15 can be attracted to the magnet 1 13. At this time, the plug rod 15 can limit the main body 1 and the connector 2. A pipe connected to the fire extinguisher is set at the other end of the connector 2, so that the main body 1 is connected to the connector 2, effectively ensuring the stability of the main body 1 during installation, and preventing the main body 1 from falling off when the subsequent fire extinguisher is used, affecting the progress of fire extinguishing work;
