In cold season, the glass smoke exhaust window can cause the loss of a large amount of indoor heat, increasing energy consumption. At the same time, in hot season, the glass can absorb a large amount of heat, increasing the load of air conditioner. SUMMARY
[0003] In order to overcome at least one defect of the prior art, the utility model provides a smoke exhaust window and building, which can solve the problems of poor corrosion resistance of traditional metal frame and poor heat preservation performance of glass window.
[0004] The utility model discloses a technical scheme that is adopted to solve the problem is:

[0006] An outer window frame has a first mounting groove;
[0007] An inner window frame is fixedly or rotatably installed in the first mounting groove, and the inner window frame has a second mounting groove;
[0008] A window surface is assembled in the second mounting groove, and the window surface is made of rock wool sandwiched aluminum plate or honeycomb aluminum plate;
[0009] When the inner window frame is rotatably installed in the first mounting groove, the inner window frame is further connected with a push-pull device for reciprocating rotation of the inner window frame.
[0010] By using the above scheme, the rock wool sandwiched aluminum plate or honeycomb aluminum plate is used as the window surface material, which has excellent heat preservation and insulation performance, can effectively prevent the loss of indoor heat, especially in cold season, helps to reduce energy consumption and improve the energy-saving effect of the building. Compared with traditional glass, the rock wool sandwiched aluminum plate and the honeycomb aluminum plate have higher impact resistance, can effectively resist the impact of wind pressure, hail and other extreme weather conditions, and improve the durability and safety of the smoke exhaust window. In addition, the rock wool sandwiched aluminum plate or the honeycomb aluminum plate as the window surface material is not easy to rust, reducing the maintenance cost.
[0011] Further, the outer window frame is made of aluminum profile, and a cavity is arranged in the length direction of the outer window frame, and a heat insulation strip is arranged in the cavity.
[0012] By using the above scheme, the heat insulation strip arranged in the cavity can effectively divide the outer window frame into two parts, forming a broken bridge structure. This broken bridge design can significantly reduce the conduction of heat through the window frame, thereby improving the heat insulation performance of the entire smoke exhaust window. In summer, it can reduce the entry of outdoor heat into the room, reducing the air conditioning load; in winter, it can reduce the loss of indoor heat, improving the heat preservation effect. The outer window frame made of aluminum profile has excellent corrosion resistance and will not rust and corrode like traditional metal window frames in humid environments. This not only maintains the appearance of the smoke exhaust window, but also prolongs its service life and greatly reduces maintenance costs. Users do not need to regularly perform maintenance work such as rust removal and painting, saving time and cost.
[0013] Further, the heat insulation strip is provided in multiple, and the multiple heat insulation strips are evenly arranged in the cavity.
[0014] By using the above scheme, the multiple heat insulation strips are evenly distributed in the cavity, forming multiple layers of heat insulation barriers, effectively blocking the conduction of heat through the window frame. This multi-layer heat insulation design can significantly improve the heat insulation performance of the entire smoke exhaust window, reducing the energy loss caused by the temperature difference between indoor and outdoor. In summer, it can effectively block the entry of outdoor heat into the room, reducing the air conditioning load; in winter, it can reduce the loss of indoor heat, improving the heat preservation effect. The multiple heat insulation strips not only have heat insulation effect, but also can enhance the structural stability of the window frame. The evenly distributed heat insulation strips can form multiple support points in the cavity, disperse external force, improve the overall rigidity and anti-deformation ability of the window frame, and ensure the reliability and safety under various weather conditions.
[0015] Further, the push-pull device comprises a power box, a first connecting rod and a second connecting rod, the power box has an output shaft, the opposite ends of the first connecting rod are fixed end and sliding end, the fixed end is fixedly connected with the output shaft, so that the fixed end rotates with the rotation of the output shaft;
[0016] The second connecting rod is provided with a sliding groove, and the sliding end is slidably arranged in the sliding groove and can rotate in the sliding groove;
[0017] The second connecting rod is fixedly connected with the inner window frame.
[0018] By using the above scheme, the second connecting rod is provided with a sliding groove, and the sliding end is slidably arranged in the sliding groove and can rotate in the sliding groove. This design ensures that the sliding end not only rotates in the sliding groove, but also slides in the sliding groove during the rotation of the first connecting rod. This combined motion can realize the precise push-pull of the inner window frame, ensuring the smoothness and stability of the window during opening and closing.
[0019] Further, the power box comprises a shell, a motor, a reducer, a battery and a controller, the battery is in transmission connection with the reducer, the output shaft is the output shaft of the reducer, the controller is electrically connected with the motor and the battery respectively, the battery, the reducer, the battery and the controller are located inside the shell, and the output shaft is fixedly connected with the fixed end by penetrating the shell.
[0020] By adopting the above scheme, all key components (motor, reducer, battery and controller) are integrated in the shell, reducing the influence of the external environment on these components and improving the stability and reliability of the system. This integrated design makes the power box compact in structure, easy to install and maintain. The controller can realize precise control of the motor, making the opening and closing of the smoke exhaust window more convenient and safe. Especially in high and large space buildings, manual opening of the smoke exhaust window has safety hazards, especially in high and large space buildings such as exhibition halls and theaters. Remote control of electric control can ensure that the smoke exhaust window is quickly and safely opened in emergency situations, ensuring the safe evacuation of personnel and fire fighting.
[0021] Further, the controller is further electrically connected with an abnormality sensor, and the abnormality sensor is used for monitoring the abnormality near the power box.
[0022] By adopting the above scheme, the abnormality sensor can monitor the environmental conditions such as smoke and temperature near the power box in real time. Once an abnormal situation (such as fire or overheating) is detected, the controller can take immediate action, such as automatically opening the smoke exhaust window, to ensure a quick response in emergency situations and ensure the safe evacuation of personnel and fire fighting. Even if the total controller of the exhibition hall, theater and other places is damaged and cannot remotely control the push-pull device, the push-pull device can still automatically open the smoke exhaust window based on the signal of the abnormality sensor, thereby improving the reliability of the smoke exhaust window.
[0023] Further, the abnormality sensor comprises one or a combination of a smoke sensor and a temperature sensor.
[0024] By adopting the above scheme, the smoke sensor can monitor the smoke concentration around the power box in real time, and once the smoke is detected, a signal is sent to the controller, and the controller can quickly start the opening program of the smoke exhaust window. Even if the remote control system is damaged or fails, the smoke sensor can still detect signs of fire and trigger the automatic opening of the smoke exhaust window, ensuring that the smoke is quickly exhausted in the early stage of the fire to gain valuable time for personnel evacuation.
[0025] The temperature sensor can monitor the temperature change around the power cartridge in real time, and once the temperature exceeds the preset threshold, a signal is sent to the controller, which can take corresponding measures such as stopping the motor operation, starting the cooling system, etc., to prevent overheating of the equipment and cause accidents. When the remote control system fails, the temperature sensor can also automatically detect the overheating condition and trigger the automatic opening of the smoke exhaust window to prevent the spread of fire.
[0026] The combination of the smoke sensor and the temperature sensor can provide more comprehensive environmental monitoring data, and the controller can automatically adjust the start and stop of the motor according to these data. Even if the remote control fails, the controller can still automatically adjust according to the sensor data to ensure normal operation.
[0027] Further, the shell is provided with a battery slot, the battery is assembled in the battery slot, and a pressure relief channel is arranged at the battery slot and extends to the outside of the shell.
[0028] By adopting the above scheme, during use, especially in extreme conditions such as high temperature or fire, the battery may generate a large amount of gas due to overheating, short circuit, etc., causing the pressure in the battery slot to rise sharply. The design of the pressure relief channel can release these gases in time to prevent the pressure in the battery slot from being too high, thereby avoiding battery explosion. This is particularly important in emergency situations such as fires, which can prevent secondary damage to the surrounding environment and personnel caused by battery explosion, and improve the overall safety of the system.
[0029] Further, the second connecting rod is connected to the upper part of the inner window frame, or the second connecting rod is connected to the lower part of the inner window frame.

[0032] By adopting the above scheme, the smoke exhaust window is arranged on the building facade, which reduces the direct contact area with falling hail compared with roof smoke exhaust window. In extreme weather conditions such as hail, the impact force on the facade smoke exhaust window is smaller, reducing the risk of damage to the smoke exhaust window by hail, ensuring the structural integrity and normal function of the smoke exhaust window. The design of the facade smoke exhaust window can effectively prevent rainwater penetration and reduce damage to the building interior caused by rainwater. Even in extreme weather conditions such as heavy rain, the facade smoke exhaust window can maintain good waterproof performance to ensure the dryness and safety of the building interior.

The power box 41 has an output shaft 4131. The opposite ends of the first connecting rod 42 are a fixed end 421 and a sliding end 422. The fixed end 421 is fixedly connected with the output shaft 4131, so that the fixed end 421 rotates with the rotation of the output shaft 4131. The second connecting rod 43 is provided with a sliding groove 431, and the sliding end 422 is slidably arranged in the sliding groove 431 and can rotate in the sliding groove 431. The second connecting rod 43 is fixedly connected with the inner window frame 2.
[0054] Specifically, the second connecting rod 43 is provided with a sliding groove 431, and the sliding end 422 is slidably arranged in the sliding groove 431 and can rotate in the sliding groove 431. This design ensures that the sliding end 422 not only rotates in the sliding groove 431 but also slides in the sliding groove 431 during the rotation of the first connecting rod 42.

When the remote control system fails, the temperature sensor can still detect the overheating condition autonomously and trigger the automatic opening of the smoke exhaust window to prevent the spread of fire.
[0063] The combination of the smoke sensor and the temperature sensor can provide more comprehensive environmental monitoring data, and the controller 415 can automatically adjust the start and stop of the motor 412 according to these data. Even if the remote control fails, the controller 415 can still adjust autonomously according to the sensor data to ensure normal operation.

[0065] Specifically, during use, especially in extreme conditions such as high temperature or fire, the battery 414 may generate a large amount of gas due to overheating, short circuit, etc., causing the pressure in the battery slot 4111 to rise sharply. The design of the pressure relief channel 4112 can release these gases in time, preventing the pressure in the battery slot 4111 from being too high, thereby avoiding the explosion of the battery 414.
