Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Embodiment 1

[0028] A sliding-door anti-smoke escape range hood, as Figures 1 - 6 shown, includes a range hood main body 1 equipped with a sliding door assembly. The outer side wall of the range hood main body 1 is welded with a mounting plate 4. A locking assembly is provided on the outer side wall of the mounting plate 4. A connecting pipe 29 is connected to the outer side wall of the range hood main body 1. The bottom outer wall of the range hood main body 1 is slidably connected with a connecting plate 14 through a linear slide rail. A telescopic assembly is provided at the end of the connecting plate 14. The telescopic assembly is connected to the connecting pipe 29. A grip 12 is welded on the outer side wall of the connecting plate 14. The locking assembly includes a rotating rod 17, a torsion spring 18, and an inclined groove 21. The rotating rod 17 is rotatably connected to the inner wall of the mounting plate 4. The outer side walls of both ends of the rotating rod 17 are respectively welded with a turntable 16 and a matching plate 19. The torsion spring 18 is clamped between the matching plate 19 and the outer side wall of the mounting plate 4. An annular groove 23 is opened on the outer side wall of the turntable 16. The inclined groove 21 is opened on the outer side wall of the mounting plate 4. A guide rod 24 is slidably connected to the inner wall of the inclined groove 21. An inclined plug rod 20 is welded on the outer side wall of the guide rod 24. A matching rod 22 is welded on the outer side wall of the inclined plug rod 20. The matching rod 22 is matched with the annular groove 23. The other end of the inclined plug rod 20 is movably inserted into the inner wall of the connecting rod 15;

[0029] When the sliding door assembly is used to open the oil filter, the sliding door assembly contacts the matching plate 19, and the matching plate 19 drives the rotating rod 17 to rotate, thereby causing the turntable 16 to rotate, and the oblique insertion rod 20 moves toward the outside of the connecting rod 15 under the cooperation of the matching rod 22 and the annular groove 23, canceling the lock of the connecting rod 15, and then the connecting rod 15 can be slid horizontally to absorb the residual oil smoke on the side and input it into the range hood body 1 through the connecting pipe 29.

[0030] The sliding door assembly includes a fixed plate 2, a PVC door curtain 3, a mounting box 5, and a movable plate 9. The mounting box 5 is fixed to the outer side wall of the range hood body 1 by bolts. The inner wall of the mounting box 5 is rotatably connected with a winding roller 6. The outer side wall of the winding roller 6 is sleeved with a coil spring 7. The two ends of the coil spring 7 respectively abut between the mounting box 5 and the winding roller 6. One end of the PVC door curtain 3 is connected to the winding roller 6. The movable plate 9 is slidably connected to the outer side wall of the range hood body 1. The fixed plate 2 is fixed to the outer side wall of the range hood body 1 by bolts. The other end of the PVC door curtain 3 is connected to the movable plate 9. The inner wall of the movable plate 9 is slidably connected with a plug plate 8. A spring 11 is welded between the plug plate 8 and the inner wall of the movable plate 9. The other end of the plug plate 8 is movably plugged into the inner wall of the fixed plate 2. The outer side wall of the movable plate 9 is welded with a moving rod 10.

[0031] When the range hood body 1 needs to be opened, the plug plate 8 is pulled to make the plug plate 8 disengage from the fixed plate 2, and then the movable plate 9 is slid horizontally, and the winding roller 6 reels the PVC door curtain 3 driven by the winding spring 7. This structure is a soft door structure, so it is a sliding door type. At the same time, the moving rod 10 rotates against the matching plate 19, thereby realizing the unlocking of the connecting rod 15, and then the sliding connecting rod 15 can be used normally to inhale the residual oil smoke on the side through the telescopic component.

[0032] Working principle: when the range hood main body 1 needs to be opened, the plug plate 8 is pulled to make the plug plate 8 disengage from the fixed plate 2, and then the movable plate 9 is slid horizontally, and the winding roller 6 reels the PVC door curtain 3 driven by the winding spring 7. This structure is a soft door structure, so it is a sliding door type. At the same time, the moving rod 10 resists the rotation of the matching plate 19, and the matching plate 19 drives the rotating rod 17 to rotate, thereby rotating the turntable 16, and the obliquely inserted rod 20 moves to the outside of the connecting rod 15 under the cooperation of the matching rod 22 and the annular groove 23, canceling the lock of the connecting rod 15, and then the connecting rod 15 can be slid horizontally to inhale the residual oil smoke on the side, and input it into the range hood main body 1 through the connecting pipe 29. Example 2

[0033] A sliding door type smoke evacuation prevention range hood, such as Figures 1 - 3As shown, the telescopic assembly includes multiple groups of plastic rings 13 and folding tubes 28, multiple groups of the top inner walls of the plastic rings 13 are bonded with iron tubes 25, multiple groups of the bottom outer walls of the plastic rings 13 are bonded with magnets 26, the iron tubes 25 cooperate with the magnets 26, multiple groups of the folding tubes 28 are bonded with connecting rings 27, multiple groups of the folding tubes 28 have their two ends connected to the inner walls of the two ends of the plastic rings 13, and the folding tubes 28 are connected to the connecting tubes 29;

[0034] Working principle: Before sliding the connecting plate 14, the plastic rings 13 at different positions can be pulled to separate the iron tube 25 from the adsorption of the magnet 26, and then the plastic ring 13 is pulled. The plastic ring 13 and the connecting ring 27 cooperate to achieve the elongation of the folding tube 28, which can achieve the absorption of oil smoke at different positions while protecting the safety of the folding tube 28.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
