  The present invention relates to an exhaust heat fire prevention device, and more particularly, to an exhaust heat fire prevention device that can block heat, flame, and smoke and meets the provisions of fire prevention equipment.

  A common conventional fire prevention device is the “Fire Screen Device” of the Chinese Patent Publication No. 373655, which mainly includes a fire screen, a fire screen drive unit, a control unit, and a detection unit. The fire screen drive unit has two types: manual rope and electric motor. The motor is operated by driving the motor directly when the switch braking or detection unit in the control box detects the fire occurrence. . The feature is that the fire screen is installed in a roll-up manner, and a weight is provided at the lower end of the fire screen. When the fire screen is opened, the fire screen smoothly hangs as close as possible to the ground, improving the barrier effect. It is. Also, the fire screen is provided with one or more longitudinal tears, and the tears reach the lower end to form an emergency exit.

  The above-mentioned conventional "fire screen device" keeps the emergency exit at the same time as separating the misfire area so that people in the misfire area can escape, but the high-temperature radiant heat generated in the event of a fire is outside the misfire area. In addition to causing inflammables in nearby areas, hurting human bodies, and adding smoke, this smoke is the main cause of death. There is a provision (Article 79 of Architectural Design and Construction) that must have a thermal barrier property, and if such a conventional "fire screen device" is simply a fire prevention equipment, it conforms to the relevant fire prevention equipment regulations In addition, heat, flame and smoke cannot be blocked. For this reason, a general conventional “fire screen device” cannot meet the needs of the user in actual use.

  The present invention is an improvement of the Chinese Patent Application No. 93220985, in which the inventor uses a storage mechanism, two shut-off screens, at least one sensor unit and at least one control unit to create a two-layer fire screen. Configure the device. When the sensor unit senses hot air or smoke in the environment, or when the user manually operates the control unit, the first and second drive units in the storage mechanism are activated to suspend the two shut-off screens, The air layer formed between two shielding screens can be used to shield heat and flame. However, the inventor still thought that this was not perfect, and research has led to the development of an exhaust heat fire-fighting device with further superior functions.

  For this reason, the main purpose of the present invention is to use a mist spraying unit in the event of a fire, increase the surface area of the entire liquid by the atomized liquid, enhance the heat transfer rate characteristics, and quickly transfer heat energy to the outside.
