[0028] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0030] Please refer to Figures 1 to 5 , a fire smoke exhaust device provided by an embodiment of the present utility model includes: a smoke exhaust fan 1, an adjustment structure 3 and an auxiliary structure 4. An air inlet pipe 2 is installed on one side of the smoke exhaust fan 1 by means of the auxiliary structure 4. An adjustment structure 3 is provided on the side of the smoke exhaust fan 1 away from the air inlet pipe 2, and an auxiliary structure 4 is provided on the side of the smoke exhaust fan 1 close to the air inlet pipe 2.

[0031] In an embodiment of the present utility model, please refer to Figures 1 to 4 , the adjustment structure 3 includes a circular rail 301 and a corrugated pipe 302. The circular rail 301 and the corrugated pipe 302 are fixedly connected to the smoke exhaust fan 1. A sliding frame 303 is slidably connected to the arc surface of the circular rail 301. A positioning rod 304 is threadedly inserted into one side of the sliding frame 303. One end of the positioning rod 304 close to the circular rail 301 is rotatably connected to a clamping plate 305. Both sides of the clamping plate 305 are slidably connected to the circular rail 301 and the smoke exhaust fan 1. A mounting frame 308 is fixedly connected to the side of the sliding frame 303 away from the smoke exhaust fan 1. A mounting rod 309 is threadedly inserted into one side of the mounting frame 308. An installation ring 311 is fixedly connected to the arc surface of the corrugated pipe 302. The installation ring 311 is slidably connected to the inner wall of the mounting frame 308. A plurality of installation holes 312 are formed on the surface of the installation ring 311. The inner wall of one of the installation holes 312 is slidably connected to the mounting rod 309. According to the actual situation of the installation position of the smoke exhaust fan 1, the angle orientation of the corrugated pipe 302 is adjusted, thereby changing the direction of smoke exhaust. The orientation angle of the corrugated pipe 302 can be adjusted in multiple directions. The fixing operation is simple and convenient, and the practicability is high. An anti-slip pad 306 is fixedly connected to the side of the clamping plate 305 away from the positioning rod 304. The anti-slip pad 306 is a rubber pad. The friction between the clamping plate 305 and the circular rail 301 is increased through the anti-slip pad 306, so that the limiting effect of the clamping plate 305 is better. A limiting rod 307 is fixedly connected to the side of the clamping plate 305 close to the positioning rod 304. The arc surface of the limiting rod 307 is slidably connected to the sliding frame 303. The clamping plate 305 is further limited through the limiting rod 307, so that the clamping plate 305 moves more stably. A plurality of anti-slip protrusions 310 are fixedly connected to the end of the mounting rod 309 away from the mounting frame 308. The plurality of anti-slip protrusions 310 are evenly distributed on the mounting rod 309. The friction of the operating end of the mounting rod 309 is increased through the anti-slip protrusions 310, which is convenient for the user to rotate the mounting rod 309;

[0032] In an embodiment of the present utility model, please refer to Figure 5 , the auxiliary structure 4 includes an auxiliary rod 41. The auxiliary rod 41 is rotatably connected to the exhaust fan 1. An auxiliary frame 42 is threadedly connected to the arc surface of the auxiliary rod 41. Two round rods 43 are fixedly connected to one side of the exhaust fan 1 close to the auxiliary rod 41. The arc surfaces of the two round rods 43 are slidably connected to the auxiliary frame 42. An auxiliary ring 44 is fixedly connected to one end of the smoke inlet pipe 2 close to the exhaust fan 1. The auxiliary frame 42 is used to tightly press the auxiliary ring 44 against the exhaust fan 1, so that the smoke inlet pipe 2 is fixed to the exhaust fan 1. The installation operation is simple and convenient, improving the installation efficiency. A support strip 45 is fixedly connected to one side of the exhaust fan 1 close to the auxiliary frame 42. The thickness of the support strip 45 is less than the thickness of the auxiliary ring 44. The support strip 45 is used to support the auxiliary ring 44, facilitating the user to apply force and position the auxiliary ring 44. A sealing gasket 46 is fixedly connected to one side of the auxiliary ring 44 away from the smoke inlet pipe 2. The cross section of the sealing gasket 46 is circular. The airtightness between the auxiliary ring 44 and the exhaust fan 1 is increased through the sealing gasket 46;

[0033] The working principle of a fire exhaust device provided by the present utility model is as follows: By setting the adjustment structure 3, first pull the mounting ring 311 and the corrugated pipe 302 according to requirements, so that the corrugated pipe 302 extends a certain distance to ensure that the corrugated pipe 302 is still slightly away from the mounting frame 308 after subsequent rotation. Then rotate the mounting ring 311 and the corrugated pipe 302 to a specified angle and the bending angle of the corrugated pipe 302 is 90°, and hold it. Then move the sliding frame 303 along the circular track 301. The sliding frame 303 drives the mounting frame 308 to move until the mounting frame 308 is aligned with the mounting ring 311. Then, on the premise of maintaining the angle orientation and bending angle of the corrugated pipe 302, contract the corrugated pipe 302 so that the mounting ring 311 slides into the inner wall of the mounting frame 308. Rotate the mounting rod 309. The mounting rod 309 slides into the corresponding mounting hole 312 along the mounting frame 308 by means of the thread, so that the mounting ring 311 is fixed to the mounting frame 308. Then rotate the positioning rod 304. The positioning rod 304 moves along the sliding frame 303 towards the direction close to the circular track 301 by means of the thread. The positioning rod 304 drives the clamping plate 305 to tightly press against the circular track 301, so that the positions of the sliding frame 303 and the mounting frame 308 are fixed. Among them, the friction between the clamping plate 305 and the circular track 301 is increased through the anti-slip pad 306, so that the limiting effect of the clamping plate 305 is better. The clamping plate 305 is further limited by the limiting rod 307, so that the clamping plate 305 moves more stably. The friction of the operating end of the mounting rod 309 is increased through the anti-slip protrusion 310, facilitating the user to rotate the mounting rod 309.

[0034] By setting the auxiliary structure 4, first rotate the auxiliary rod 41. The auxiliary rod 41 drives the auxiliary frame 42 to move away from the smoke exhaust fan 1 by means of the thread. During this process, the auxiliary frame 42 always slides along the round rod 43. After the auxiliary frame 42 moves a certain distance away from the smoke exhaust fan 1, operate the auxiliary ring 44 and the smoke inlet pipe 2, and move them downward along the side of the smoke exhaust fan 1 close to the auxiliary frame 42 to ensure that the smoke inlet pipe 2 slides into the auxiliary frame 42, and the auxiliary ring 44 is located between the auxiliary frame 42 and the smoke exhaust fan 1. Then rotate the auxiliary rod 41 in the reverse direction. The auxiliary rod 41 drives the auxiliary frame 42 to move towards the smoke exhaust fan 1 by means of the thread until the auxiliary frame 42 tightly presses the auxiliary ring 44 against the smoke exhaust fan 1, thereby fixing the smoke inlet pipe 2 on the smoke exhaust fan 1. Among them, the support bar 45 is used to support the auxiliary ring 44, which is convenient for the user to exert force and position the auxiliary ring 44. The airtightness between the auxiliary ring 44 and the smoke exhaust fan 1 is increased by the gasket 46.

[0035] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated here.

[0036] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
