[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0033] Please see Figures 1-5 As shown, this embodiment is a fire safety ventilation device, including:
[0034] The processing component includes a base 1 and a fan 8, with the fan 8 fixedly connected to the upper end face of the base 1.
[0035] The adjusting component includes a fixed rod 20, a first support frame 21, a through hole 22, a rotating rod, a disc 25, a limiting ring 26, a rotating plate 23, a connecting rod, a sleeve 14, and a knob 27.
[0036] A fixing rod 20 is fixedly connected to the upper end face of the base 1. A first support frame 21 is fixedly connected to the surface of the fixing rod 20. A through hole 22 is opened in the first support frame 21. A rotating rod is rotatably installed in the through hole 22. A disc 25 is fixedly connected to one end of the rotating rod. A limit ring 26 is fixedly connected to the surface of the disc 25. Two rotating plates 23 are rotatably connected to the surface of the fixing rod 20. A connecting rod is fixedly connected between the two rotating plates 23. A sleeve 14 is connected to the outer side of the two rotating plates 23.
[0037] When the disc 25 rotates, the eccentric setting of the limiting ring 26 allows the limiting ring 26 to slide on the surface of the connecting rod, thereby causing the connecting plate to flip on the surface of the fixed rod 20, thus realizing the adjustment of the front and rear angle of the smoking hood 28.
[0038] The limiting ring 26 is fixedly installed at the eccentric position of the disc 25, and the inner wall of the limiting ring 26 is sleeved on the surface of the connecting rod.
[0039] The connecting rod can be driven when the position of the limiting ring 26 changes;
[0040] The surface of the rotating rod rotates within the through hole 22, and a knob 27 is fixedly connected to the end of the rotating rod away from the disk 25.
[0041] Working principle: When it is necessary to adjust the front and back position of the smoke hood 28, the rotating rod is controlled to rotate in the first support frame 21 by the knob 27. At the same time, the transmission disc 25 is driven to make the limiting ring 26 on the surface of the disc 25 slide down along the surface of the connecting rod. Through the lever principle, the connecting plate is driven to flip back and forth, thereby completing the adjustment of the front and back position of the smoke hood 28.
[0042] Please see Figures 1-5 As shown, this embodiment is based on the above embodiment 1, and the adjustment component further includes an adjustment rod 13, an adjustment frame 16, a limiting plate 19, an adjustment groove 15, a push plate 17, and a groove 18;
[0043] An adjusting rod 13 slides vertically inside the sleeve 14. An adjusting frame 16 is fixedly connected to the surface of the adjusting rod 13. A limiting plate 19 is rotatably connected inside the adjusting frame 16. Multiple adjusting grooves 15 are opened on the inner wall of the sleeve 14. A push plate 17 is fixedly connected to the front of the adjusting frame 16. One side of the limiting plate 19 abuts into one of the adjusting grooves 15.
[0044] The upper surface of the adjustment frame 16 has a groove 18, and the surface of the limiting plate 19 is fitted into the groove 18;
[0045] The working principle is as follows: when the height of the smoking hood 28 needs to be adjusted, the adjustment frame 16 is controlled to slide vertically in the sleeve 14 by the push plate 17. During this process, the stretching hose 11 can move and stretch and contract in coordination with the adjustment rod 13. After the position is adjusted, the limit plate 19 is controlled to flip down and abut into one of the corresponding limit grooves 30 to complete the adjustment of the limit rod. This is convenient and quick while ensuring the stability of the adjustment rod 13.
[0046] Please see Figures 1-5 As shown, this embodiment is based on the above embodiment 1, with a ventilation component. The ventilation component includes a treatment tank 2, a filter plate 4, an impeller 3, a first treatment pipe 10, a stretching hose 11, a hose 34, a sealing plate 31, a threaded rod 33, a second support frame 29, a limiting groove 30, a limiting block 32, a fume hood 28, a second treatment pipe 7, an exhaust pipe 5, and a filter screen 6.
[0047] A treatment tank 2 is fixedly connected to the upper surface of the base 1. A filter plate 4 is fixedly connected to the inner wall of the treatment tank 2. An impeller 3 is rotatably connected inside the treatment tank 2. A first treatment pipe 10 is fixedly connected to the upper surface of the fan 8. A stretching hose 11 and a hose 34 are fixedly connected to one end of the first treatment pipe 10. A sealing plate 31 is fixedly connected to the upper surface of the hose 34. A threaded rod 33 is rotatably connected to the center of the upper surface of the sealing plate 31. A second support frame 29 is threadedly connected to the surface of the threaded rod 33. The lower end face of 9 is fixedly connected to the top of the adjusting rod 13. A limiting groove 30 is opened in the inner wall of the second support frame 29. A limiting block 32 slides vertically on both sides of the limiting groove 30. The two limiting blocks 32 are fixedly connected to one side of the sealing plate 31 at opposite ends. A smoke hood 28 is fixedly connected to one end of the first processing pipe 10. A second pipe is fixedly connected inside the fan 8. The end of the second processing pipe 7 away from the fan 8 is fixedly connected inside the processing tank 2. The outlet of the second processing pipe 7 is in a relative position to the impeller 3.
[0048] An exhaust pipe 5 is fixedly connected to the inner wall of the upper end face of the treatment tank 2, and a filter screen 6 is fixedly connected inside the exhaust pipe 5.
[0049] Working principle: When the gas in the exhaust hood 28 is transferred to the first treatment pipe 10, the flow process is accelerated by the driving fan 8. Simultaneously, the gas is transferred to the treatment tank 2 through the second treatment pipe 7, where it is treated by the filter plate 4. After completion, it is discharged outwards through the exhaust pipe 5. (Reference) Figure 2 It can be seen that the outlet of the second treatment pipe 7 is in a relative position to the impeller 3. When the second treatment pipe 7 discharges smoke towards the impeller 3, with the assistance of the fan 8, it can drive the impeller 3 to rotate, disperse the smoke and prevent it from clumping, so that the smoke filtration is more uniform and comprehensive. When the smoke does not need to be treated, the threaded rod 33 is rotated counterclockwise and rotated downward, so that the limiting block 32 slides downward in the limiting groove 30. The sealing plate 31 then squeezes the hose 34, so that the inner wall of the hose 34 is squeezed and the smoke is blocked from entering the treatment tank 2 again through the fume hood 28.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
