It can quickly exhaust the smoke in the building when a fire occurs, help people evacuate safely, and also provide clear sight and sufficient oxygen for fire rescue, which is conducive to fire fighting. This kind of fan is characterized by good high temperature resistance and high efficiency, but when the equipment absorbs smoke, it is often affected by high temperature smoke, causing the temperature of the fan to continue to rise, thus causing equipment damage. Therefore, a fire smoke exhaust fan with a water mist cooling structure is needed.

[0004] However, the existing fire smoke exhaust fans still have certain defects in actual use: when discharging high-temperature smoke, the high-temperature smoke tends to transfer the temperature to the exhaust duct of the fan, causing the temperature of the fan to continue to rise. When the temperature of the fan continues to rise and cannot be cooled down, it often causes the motor to be damaged and unable to work. For this reason, we propose a fire smoke exhaust fan with a water mist cooling structure. Utility Model Content

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1-Figure 4As shown, a fire smoke exhaust fan 7 with a water mist cooling structure includes a body 1 and a spray structure 2. The spray structure 2 is installed on the side of the body 1 by bolts. When it is necessary to adsorb and discharge the smoke and dust that appear, when the circulation pipe adsorbs the smoke, the spray structure 2 sprays water mist, so that in the process of adsorbing the smoke, the smoke mixed with water mist is adsorbed out by the circulation pipe, and the water droplets inside the water mist adsorb the temperature of the smoke and the dust particles in the smoke, so that when the smoke is discharged through the exhaust channel 10 of the circulation pipe, the water mist can make the smoke pass through the circulation pipe, reducing the damage to the exhaust pipe inside the circulation pipe caused by the smoke, and the circulation pipe is connected below the spray structure 2, and the spray structure 2 and the circulation pipe are connected by a mounting block 17 to form a clamping structure, and the spray structure 2 includes a water pump 11, a water inlet pipe 12 and a connecting bracket 14, and the side of the water pump 11 away from the body 1 is connected to the water inlet pipe 12 by bolts, and the side of the water pump 11 away from the water inlet pipe 12 is installed with a connecting bracket 14.

[0023] A filter screen 4 is installed on the side of the body 1 away from the circulation pipe by bolts, wherein the filter screen 4 is used to prevent large impurities from entering the circulation pipe in a normal environment, and a spray nozzle 5 is arranged above the filter screen 4, and the spray nozzle 5 is installed in the installation groove 501 arranged on the body 1, and a connecting structure is formed between the body 1 and the spray nozzle 5 through the installation groove 501, a base 18 is arranged below the water pump 11 and the connecting bracket 14, and side panels 19 are installed on both sides of the base 18 by bolts, and a smoke sensor 20 is installed at the center of the two groups of spray nozzles 5, wherein the model of the smoke sensor 20 is: STM32F103C8T6, wherein when the spray structure 2 needs to spray water mist, the water pipe is directed to the water pump 11 The inside is filled with water, so that the water pump 11 fills water into the connecting bracket 14. At this time, the water source fills the docking pipe 13 with water through the connecting bracket 14. At this time, the docking ring is inserted into the installation groove 501 through the sealing ring 1301. At this time, the water source is poured into the spray nozzle 5 through the docking ring, so that the water source sprays water mist through the spray nozzle 5. When the spray nozzle 5 on the body 1 sprays water mist, the sprayed water mist is above the circulation pipe. When smoke appears, when the smoke floats upward, it will directly contact the water mist, so that the fan 7 inside the circulation pipe drives the fan 9 to rotate, and then the mixed water mist and smoke at the outlet of the circulation pipe are simultaneously adsorbed along the exhaust channel 10.

[0024] Three groups of docking tubes 13 are engaged on both sides of the connecting bracket 14, and sealing rings 1301 are installed on the sides of the three groups of docking tubes 13 away from the connecting bracket 14, and the spacing between the three groups of docking tubes 13 is the same, wherein the docking tubes 13 are fixed inside the mounting groove 501 set in the body 1 through the sealing rings 1301, and the spray nozzle 5 is connected to the docking tubes 13. At this time, the connection node between the two is inside the mounting groove 501. Therefore, when the spray nozzle 5 sprays water mist outward, the spray nozzle 5 limits the impact on the spray nozzle 5 through the mounting groove 501.

[0025] An exhaust passage 10 is arranged at the center of the inner wall of the circulation duct, and connecting plates 6 are installed at both ends of the inner wall of the exhaust passage 10, and a guide cover 16 is installed at the center of the two sets of connecting plates 6 by bolts.

[0026] A docking shaft 15 is connected to the side of the fan 7 away from the connecting plate 6, and a connecting ring 8 is connected to the side of the docking shaft 15 away from the fan 7, and a fan 9 is installed on the side of the connecting ring 8 away from the fan 7 through bolts, wherein the exhaust air is connected to the air guide cover through the connecting ring 8, wherein the fan 7 is placed inside the air guide cover, and the fan 7 is connected through the docking shaft 15 and the connecting ring 8 of the fan 9.

[0027] In summary, the utility model installs the body 1 on the wall through the body 1 and the spray structure 2. When fire and smoke appear in the room, the smoke sensor 20 detects the generated smoke. When smoke is detected, the water pipe is poured into the water pump 11, and the water pump 11 pours the water source into the connecting bracket 14. At this time, the water source is poured into the docking pipe 13 through the connecting bracket 14, and the docking pipe 13 is installed in the mounting groove 501 of the body 1 through the sealing ring 1301. The spray nozzle 5 is installed at the docking pipe 13. At this time, the water source is poured into the spray nozzle 5 through the docking pipe 13, and the spray nozzle 5 sprays the water source to form water mist. At the same time, the impact force exerted on the spray nozzle 5 is dispersed by the mounting groove 501 of the body 1, and the spray nozzles 5 are arranged in groups of three, respectively on both sides of the smoke sensor 20. When the spray nozzles 5 spray out, the The sprayed water mist is above the circulation channel, and the water mist sprayed by the spray nozzle 5 is fan-shaped, thereby covering the smoke near the body 1, so that the smoke and the water mist are covered, so that the fan 7 inside the circulation channel drives the fan 9 to rotate, and when the driven fan 9 rotates, wind is formed in the exhaust channel 10. At this time, the smoke at the air inlet of the exhaust channel 10 is adsorbed into the exhaust channel 10, and when the exhaust channel 10 is adsorbed, the smoke at the air inlet of the exhaust channel 10 is mixed with the water mist and adsorbed into the exhaust channel 10. The water mist can not only complete the attachment of the smoke, but also reduce the temperature of the smoke. Therefore, when the smoke mixed with the water mist is continuously discharged through the exhaust channel 10, the particles inside the smoke are prevented from causing friction to the exhaust duct, and at the same time, the high temperature of the smoke is reduced to affect the operation of the motor.
