[0002] Firefighting equipment has a vital impact on the combat capability of firefighters, and firefighting rescue helmets are the most important of firefighting equipment. Rescue helmets are protective equipment worn on the head to protect the safety of the head during emergency rescue. The original firefighting helmets used the steel helmets of the army and were made of phenolic fiberglass. Later, an internal protective mask and a combined waterproof cape were added to improve the fireproof and heat-insulating performance. Later, the cap lining was improved, the safety distance of the cap top was increased, and the impact absorption performance was improved.

[0003] For example, the public document with application number 202121689082.7 discloses a fire helmet with a heat dissipation and exhaust structure. The utility model can dissipate heat from the inside through the inner helmet and filter screen, which ensures internal air circulation while increasing the overall resistance of the fire helmet body. The double-layer protection of the inner helmet and the fire helmet body ensures the personal safety of firefighters and significantly improves the practicality. However, when the fire helmet with heat dissipation effect is worn by soldiers entering the fire scene or rescue scene, in different scenarios, especially in major explosions or earthquakes, gravel may fall or splash for the second time and directly hit the helmet body, which may cause the helmet to be concave and deformed, thereby oppressing the soldier's head and affecting the wearing and use. If the impact of the gravel is strong and directly contacts the helmet body, it may also cause the helmet to rupture, affecting the normal protective effect of the helmet and making the helmet unable to be used normally.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a fire helmet with heat dissipation effect is proposed. Utility Model Content

[0021] like Figure 1-Figure 3 As shown, a fire helmet with heat dissipation effect includes a helmet body 1, convex ribs 2 are fixedly arranged on both sides of the upper end of the outer surface of the helmet body 1, a reinforcing ring 3 is fixedly arranged circumferentially around the upper part of the outer surface of the helmet body 1, a reinforcing plate 4 is fixedly arranged on the outer surface of the helmet body 1 below the reinforcing ring 3, a supporting rib 5 is fixedly arranged on the middle part of the surface of the opposite side of the reinforcing plate 4 and the reinforcing ring 3, a sponge pad 6 is fixedly arranged on the inner surface of the helmet body 1, an air intake mechanism 7 is arranged in the groove body of the support rib 5 on the surface of the helmet body 1, and exhaust mesh holes 8 are opened on both ends of the lower end edge of the outer surface of the helmet body 1, and the exhaust mesh holes 8 penetrate the sponge pad 6.

[0022] By adopting the above technical solution, the reinforcing ring 3, the reinforcing plate 4 and the supporting ribs 5 form a side covering body, which covers and strengthens the surroundings of the helmet body 1 to prevent the broken helmet body 1 from being directly contacted by gravel and causing breakage;

[0023] The convex rib 2 can preferentially contact the falling stones from above, so as to prevent the stones from directly hitting the helmet body 1 and causing damage;

[0024] The air intake mechanism 7 can dissipate heat inside the helmet body 1 and discharge carbon dioxide and hot air through the exhaust mesh 8.

[0025] Furthermore, the shape of the convex rib 2 is set to be a triangle, the reinforcement ring 3 is an annular rib, and the shape of the reinforcement plate 4 is set to be a semi-annular plate.

[0026] By adopting the above technical solution, the triangular apex of the convex rib 2 can also cause the force of the falling stone to deflect to a certain extent so that it bounces away, thereby reducing the force on the helmet body 1.

[0027] Furthermore, the air inlet mechanism 7 includes a mounting tube 701 fixedly arranged on the inner walls of the left and right sides of the surface of the helmet body 1 , and a filter plate 702 is fixedly arranged on the front end of the inner surface of the mounting tube 701 .

[0028] By adopting the above technical solution, the filter plate 702 can block impurities in the external air and prevent the impurities from entering the helmet body 1 along with the air.

[0029] Furthermore, the air intake mechanism 7 also includes a micro suction pump 703 fixedly installed on the rear side of the inner surface of the mounting tube 701, and the rear end of the micro suction pump 703 is connected to an air pipe 704 through a pipeline, and the air pipe 704 is semi-circularly arranged in the inner wall of the helmet body 1.

[0030] By adopting the above technical solution, the external air sucked by the micro suction pump 703 can be discharged into the trachea 704.

[0031] Furthermore, the air inlet mechanism 7 also includes an exhaust port 705 fixedly provided on the inner side surface of the air pipe 704. The exhaust port 705 penetrates the sponge pad 6 and is connected with the interior of the helmet body 1. The exhaust port 705 is a soft rubber tube.

[0032] By adopting the above technical solution, the exhaust port 705 can send the air in the air pipe 704 into the interior of the helmet body 1, thereby cooling and dissipating the heat.

[0033] Furthermore, a steel ring 9 is rotatably provided on the surface of the reinforcing ring 3 , and a tempered glass cover 10 is fixedly provided on the bottom end of the steel ring 9 .

[0034] By adopting the above technical solution, the tempered glass cover 10 can cover the soldier's face for protection by rotating the steel ring 9.

[0035] Furthermore, a heat-insulating cape 11 is fixedly installed on the four edges of the lower outer surface of the helmet body 1 through buckles, and a searchlight 12 is fixedly arranged at the middle of the top of the helmet body 1.

[0036] By adopting the above technical solution, the heat-insulating shawl 11 can protect the soldier's neck and avoid burns.

[0037] Working principle: When using the fire helmet with heat dissipation effect, first, when the soldier wears the fire helmet, the soldier's head first contacts the sponge pad 6, the heat-insulating shawl 11 covers the soldier's neck, and then the tempered glass cover 10 is turned downward to achieve overall protection of the soldier's head position. When entering the fire scene, the micro suction pump 703 is started, and the outside air is sucked in through the micro suction pump 703. After the impurities are filtered through the filter plate 702, the air is discharged into the trachea 704. Under the continuous input air pressure, the air will be evenly blown into the interior of the helmet body 1 through the exhaust port 705 to cool and dissipate the heat inside the helmet body 1. The hot air inside the helmet body 1 will be discharged through the exhaust mesh 8 under high pressure. At the same time, the carbon dioxide gas exhaled by the soldier in the helmet body 1 is also It will be discharged from the exhaust mesh 8 on both sides of the bottom along with the input air. In the fire scene or other rescue scenes, gravel or other splashing objects fall and hit the helmet body 1. Through the triangular protrusions of the convex rib 2, they will preferentially contact the gravel, and the triangular apex can also make the force of the falling gravel offset to a certain extent so that it will bounce off, thereby reducing the force on the helmet body 1. The reinforcing ring 3, the reinforcing plate 4 and the supporting rib 5 form a side covering body, which covers and strengthens the protection of the helmet body 1 all around to prevent the gravel from directly contacting the helmet body 1 and causing breakage. At the same time, the impact caused by the collision of gravel or other splashing objects will be buffered by the sponge pad 6, which can greatly reduce the damage to the soldier's head caused by the collision impact. This is the working principle of the fire helmet with heat dissipation effect.
