[0002] With the acceleration of urbanization and the rapid development of the construction industry, high-rise buildings have sprung up like mushrooms after a rain. The resulting safety issues cannot be ignored, among which fire safety is particularly important. Fire training is an effective way to improve the fire prevention and emergency escape capabilities of firefighters and ordinary citizens. However, existing fire training methods mostly rely on traditional teaching models and equipment, which often make it difficult to provide a comprehensive and realistic fire and smoke simulation environment, resulting in a large gap between the training effect and the actual combat environment.
[0003] Traditional training devices can usually only simulate simple fire or smoke conditions, lacking the two key factors of flame spread and smoke diffusion. This single simulation method is difficult to fully display the dynamic characteristics of complex fires. For trainees, this lacks the understanding of the complexity of actual fires and the cultivation of coping capabilities.
[0004] In addition, in existing training methods, the specific actions of trainees during the evacuation process are often difficult to record and quantify, making it difficult to evaluate the effectiveness of evacuation training based on the trainees' behavior. Utility Model Content

Natural non-toxic pigments are placed in the pigment box 11. The natural non-toxic pigments are evenly mixed in the smoke along with the smoke machine 7.
[0030] More specifically, the fan 1 injects gas into the main pipe 3, and then the gas diverter 4 diverts the gas and supplies it to the fixed frame 4 and the smoke machine 7, so as to simulate the fire and smoke conditions, and the colorant 10 and the pigment are used to mark the trainees, so as to facilitate the quantification of the trainees' performance;
[0031] Preferably, the gas diverter 4 is provided with a branch interface 9, the branch interface 9 is fixedly connected with a branch pipe 8, and the gas diverter 4 is fixedly connected with a branch system through the branch pipe 8.
[0032] More specifically, the branch flow system extends the control range of a single fan 1 through the branch flow pipe 8, thereby increasing the area of the simulated fire.
[0033] Preferably, the branch flow system includes a fixing frame 5 and red gauze 6 and a colorant 10 for simulating fire, a smoke machine 7 and a pigment box 11 for simulating smoke, and the gas diverter 4.
[0034] More specifically, the branch system is supplied with airflow through the gas diverter 4 to simulate the spread of fire, which is more realistic.
[0035] Preferably, the colorant 10 is a non-toxic developer, and the clothes worn by the trainees come into contact with the developer to develop color.
[0036] Preferably, the color of the colorant 10 is different from the color of the non-toxic plant pigment in the pigment box 11 .
[0037] More specifically, the different colors of the colorant 10 and the pigment facilitate the distinction between smoke and fire injuries received by the trainees, and further facilitate the quantification of the trainees' performance.

[0044] Working principle:
[0045] Airflow generation: When the training starts, fan 1 starts and generates airflow, which is then transmitted to the main pipe 3 through the air outlet 2.
[0046] Fire simulation: The airflow reaches the gas diverter 4 and is distributed to the fixing frame 5. The airflow overflows from the opening at the top of the fixing frame, blowing the red gauze 6, causing the gauze to dance, and cooperate with the colorant 10 on the surface to simulate the fire source.
[0047] Smoke simulation: At the same time, the gas diverter 4 delivers part of the airflow to the smoke machine 7. The non-toxic pigment in the pigment box 11 generates pigmented smoke to simulate the smoke in the fire.
[0048] Spread and expansion: The branch flow system receives airflow through the branch flow interface 9 and the branch flow pipe 8, thereby simulating the spread of fire in a larger area.
[0049] Color marking: During the emergency evacuation process, trainees may come into contact with gauze 6 or be surrounded by smoke 7. The colorant 10 and the pigment in the smoke will be marked on their clothes. Different colors are used to distinguish between fire injuries and smoke injuries, which is convenient for subsequent quantitative analysis of the results.
[0050] Flexible control: Fan 1 is a variable frequency fan, which can adjust the airflow speed according to the needs of training to achieve changes in the speed of simulated fire spread.
[0051] Reduce interference: To ensure that the evacuation training of trainees is not disturbed, the main pipe 3 and the branch pipe 8 are made of soft materials to reduce the risk of tripping.
[0052] The utility model not only provides a highly simulated fire environment, but also can realize accurate recording and analysis of the behavior of trainees, thus providing a new and effective tool for the field of fire safety education and training.
[0053] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
