Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a kitchen fume duct with a fire-fighting function. Background Art
[0002] The fire of the kitchen fume duct body is a very dangerous fire hazard, and its harm should not be underestimated. A large amount of grease and dirt has accumulated inside the long-term use of the fume duct body. These substances are very easy to burn at high temperatures. Once a fire occurs, the fire will spread rapidly and produce a large amount of toxic smoke. These fumes not only cause serious harm to human health, but also reduce visibility, making it difficult for people to escape in a fire. In addition, the fire of the fume duct body may also cause other fire accidents, such as igniting surrounding combustibles, and even causing a fire in the entire building. Therefore, the fire of the kitchen fume duct body is extremely harmful and must be given enough attention. In order to protect people's lives and property, the fume duct body must be cleaned regularly, and the fume duct body fire extinguishing device must be installed at the same time to strengthen the implementation of fire prevention measures.
[0003] Existing oil flue body fire extinguishing devices mainly rely on dry powder fire extinguishers. When the oil flue body catches fire, it is necessary to open the dry powder fire extinguisher, which sprays dry powder fire extinguishing agent into the oil flue body through a pipeline to suppress the spread of flames, thereby preventing the fire from further increasing.
[0004] However, in actual applications, the oil fume duct body catches fire very quickly, and since the oil fume duct body is connected to the outside air, the outside air will quickly enter the oil fume duct body, further aggravating the spread of the fire. Therefore, the actual fire extinguishing effect is often not ideal, and it is difficult to effectively curb the spread of the fire. Summary of the invention
[0005] Aiming at the problem that air entering into an oil fume duct body may aggravate the fire, the utility model provides a kitchen oil fume duct with a fire extinguishing function which can block air from entering into the oil fume duct body and avoid aggravation of the fire.
[0006] In order to solve the above problems, the technical solution adopted by the utility model is a kitchen oil fume duct with fire extinguishing function, including an oil fume duct body, a connecting pipe is arranged outside the oil fume duct body, one end of the connecting pipe is connected to the inside of the oil fume duct body, and the other end of the connecting pipe is connected to a fire extinguisher; a sealing member is arranged at one end of the oil fume duct body connected to the outside, the upper end of the sealing member is fixedly connected to the top of the oil fume duct body, a pulley block is arranged on the fire extinguisher, one end of the pulley block is connected to the fire extinguisher, and the other end of the pulley block is fixedly connected to the lower end of the sealing member, and the pulley block can tighten the sealing member to seal the oil fume duct body. When the oil fume duct body is found to be on fire, the fire extinguisher is opened, and the fire extinguishing agent is sprayed into the oil fume duct body through the connecting pipe, and the fire is extinguished directly at the fire point. At the same time, the pulley block is pulled to move the sealing member, and the oil fume duct body is sealed to prevent the outside air from entering, thereby curbing the spread of the fire and improving the fire extinguishing efficiency.
[0007] Preferably, one end of the connecting pipe is connected to the end of the oil fume duct body away from the outside world. Grease in the oil fume duct body is mostly gathered at the end away from the outside world. Since the grease is thickly accumulated here, it is easy to cause a fire. The connecting pipe is directly connected to this end, so that the fire extinguishing agent can be quickly and accurately sprayed to the fire point, thereby effectively extinguishing the fire.
[0008] Preferably, a one-way valve is installed on the connecting pipe. The function of the one-way valve is to ensure that the fire extinguishing agent can only flow from the fire extinguisher to the fire point, effectively preventing the fire extinguishing agent from flowing back, thereby ensuring the safety of the fire extinguishing process.
[0009] Preferably, the upper part of the end of the oil fume duct body connected to the outside is longer than the lower part. Such a structure is conducive to the smooth discharge of oil fume, and can effectively prevent rainwater from flowing back, ensuring that the inside of the oil fume duct body remains dry.
[0010] Preferably, the height of the connection between the connecting pipe and the fire extinguisher is higher than the height of the connection between the connecting pipe and the oil flue body. Placing the fire extinguisher at a higher position is conducive to the smooth spraying of the fire extinguishing agent and improves the fire extinguishing efficiency.
[0011] Preferably, a temperature sensor is installed inside the oil flue body. The temperature sensor is installed inside the oil flue body to monitor its internal temperature in real time. Once the temperature is detected to be too high and exceeds the safe range, an alarm will be immediately issued so that the fire can be discovered and handled in time.
[0012] It can be seen from the above technical solutions that the advantages of the utility model are: when the oil flue body is found to be on fire, the fire extinguisher and the one-way valve are opened, so that the fire extinguishing agent is quickly sprayed into the oil flue body through the connecting pipe, and the fire is accurately aimed at the fire source for extinguishing. At the same time, the operator pulls the pulley block to cause the seal to move, tightly seal the oil flue body, effectively isolate the outside air, thereby suppressing the further spread of the fire and significantly improving the fire extinguishing efficiency. In summary, this device achieves efficient and safe treatment of the oil flue body fire through the dual means of direct fire extinguishing and air isolation, and the fire extinguishing effect is better.
